The Government today announced the establishment of a LawTech Fund to help law firms and barristers' chambers procure and upgrade information technology (IT) systems and arrange lawtech training courses for their staff.

In a statement, the Department of Justice said the LawTech Fund, established under the Anti-epidemic Fund, will be open for applications from April 28 and cater to small and medium-size law firms as well as barristers’ chambers.

Applications will be accepted for two months and those eligible can receive a reimbursement of up to $50,000.

The Law Society of Hong Kong and the Hong Kong Bar Association will establish a joint committee to assess the applications and arrange funding disbursement.

More than 60% of law firms and 50% of barristers' chambers in Hong Kong are expected to benefit from the funding.

As for funding eligibility, law firms or chambers must have five or fewer practising lawyers as at April 8 and at the time of granting the subsidy.

The subsidies must be used for procuring and upgrading IT systems, including but not confined to video-conferencing facilities. The lawtech training that is to receive the subsidy must be recognised and approved by the joint committee.

The application form and guidance notes are available at the homepages of the Law Society and the Bar Association.

The Secretary for Justice has given an outline of the fund and discussed lawtech in her blog.

More than 40,000 new niches at two columbaria in Tuen Mun and Fanling will open for applications from May 11, the Food & Environmental Hygiene Department announced today.

Tsang Tsui Columbarium in Tuen Mun will provide 22,680 standard niches and 220 large niches, while Wo Hop Shek Columbarium in Fanling will provide 21,720 standard niches and 330 large niches for application.

The department said applicants should only file one application form to apply for either a large or standard niche for the same deceased person.

It said applicants have to fill in the particulars of at least three deceased people when applying for a large niche.

Since the type and number of niches available in the two columbaria are different, the chance of successful allocation varies, the department added.

The application deadline is June 10.

The Buildings Department approved 13 building plans in February - four on Hong Kong Island, one in Kowloon and eight in the New Territories.

Of the approved plans, nine were for apartment and apartment-commercial developments, one was for commercial development, one was for factory and industrial developments, and two were for community services developments.

Consent was given for works to start on two building projects, which will provide 77,942 sq m of gross floor area for non-domestic use.

The department also issued 14 occupation permits - four on Hong Kong Island, one in Kowloon and nine in the New Territories.

Buildings certified for occupation have 149,306 sq m of gross floor area for domestic use involving 2,912 units, and 67,594 sq m for non-domestic use.

The declared cost of new buildings completed in the month was $3.7 billion.

The Chief Executive has reappointed Frederick Ma as Chairman of the Education University of Hong Kong (EdUHK) Council from April 25 to December 31, the Government announced today.

Secretary for Education Kevin Yeung thanked Mr Ma for accepting the reappointment, saying that under his leadership, EdUHK continues to focus on educational research, development and innovation and promoting and supporting the development of teacher education in Hong Kong by nurturing outstanding and committed educators and professionals.

Mr Ma cannot accept a three-year term up until 2023 due to personal reasons. In the meantime, the Government will identify a suitable candidate for the chairmanship of the EdUHK Council.

The Housing Authority’s Commercial Properties Committee today approved the extension of rent concessions to over 8,300 non-domestic tenants or licensees for six months from April 1 to September 30.

The authority had earlier granted a 50% rent concession to its eligible retail and factory tenants for six months from April 1.

Under the extension, their rent concession will be increased to 75% over the same period with retrospective effect from April 1. The rent concession does not include rates and air-conditioning charges.

The authority said such further measures are to support the Government's new series of measures announced in early April to relieve the financial burden of individuals and businesses.

A total of 2,450 retail and 3,300 factory tenants will benefit from the approved increase in the rent concession.

The 75% rent concession will also be extended to cover tenants and licensees of bus kiosks and most advertising signboards, as well as car park users for the monthly parking of commercial vehicles.

About 40 tenancies for bus kiosks, 80 advertising signboards and about 2,500 car park users stand to benefit from the concession.

Tenants of premises in the authority's properties which are required to be closed under relevant regulations or the Government's directions, may also apply to the authority for a 100% rent concession for the period during which they are required to be closed.

The authority added that the approved measures will be implemented as soon as possible. For rent and licence fees already paid for the months of April and May, arrangements will be made for offsetting in the payment for subsequent months.

The committee has approved three rounds of rent concessions since last September. Together with this round, the total rent and licence fees foregone by the authority is estimated to reach more than $1 billion.

The Government will launch the Subsidy Scheme for Beauty Parlours, Massage Establishments & Party Rooms under the second round of the Anti-epidemic Fund on May 11.

A sum of $1.1 billion has been earmarked for the scheme, which is expected to benefit 12,400 beauty parlours and massage establishments as well as 500 party rooms.

The subsidy is expected to be disbursed from late this month.

Under the scheme, each eligible beauty parlour or massage establishment will receive a one-off tiered subsidy of $30,000, $60,000 or $100,000, depending on its number of workers.

Each eligible party room will receive a one-off subsidy of $40,000.

Applications will only be accepted online. The application deadline is May 17.

The scheme also covers premises which are operated by social enterprises.

For premises with business registration, social enterprise operators should file their applications through the online application system.

Those without business registration should directly approach the Hong Kong Council of Social Service at 2864 2993 or by email to obtain its certification and submit their applications.

Call 1836 188 or send an email for enquiries.

Hong Kong Exchanges & Clearing Limited (HKEx) today announced that Charles Li will not seek reappointment as Chief Executive at the end of his current contract in October 2021.

The Government said it respected Mr Li's decision and expressed deep appreciation for his exemplary contribution to the development of the financial market during his tenure as HKEx Chief Executive in the past decade.

Since taking the helm in January 2010, he has led HKEx and Hong Kong’s capital market in achieving important breakthroughs one after another.

The vibrancy and growth that Mr Li has brought to Hong Kong in the capital market helps reinforce the status of Hong Kong as a leading international financial centre.

Financial Secretary Paul Chan said: "Thanks to his vision and leadership, Mr Li has laid a solid and strong foundation for our stock market, rendering Hong Kong the largest IPO market in the world for seven times in the past 11 years.

"He has been instrumental in the successful launch of mutual market access programmes between Hong Kong and the Mainland, notably the Shanghai-Hong Kong Stock Connect in 2014, which was expanded to include Shenzhen-Hong Kong Stock Connect in 2016 and Bond Connect in 2017.

"He also played a pivotal role in the launch of new listing regime in Hong Kong, the enhanced internationalisation of HKEx and its international visibility. These are all important achievements of HKEx in the past few years under Mr Li’s able leadership."

Mr Chan added that the Government is confident the HKEx board will continue to ensure the success of HKEx in the years to come.

More than 8,200 applications for the Anti-epidemic Support Scheme for Property Management Sector (ASPM) have been received, with over 3,850 approved, the Government announced today.

The approved applications involve subsidies of more than $140 million and will benefit around 22,000 building blocks and about 35,750 frontline property management workers.

Launched under the Anti-epidemic Fund, the ASPM provides subsidies to owners' organisations or property management companies of eligible buildings to provide hardship allowance to frontline property management workers.

It also provides the Anti-epidemic Cleansing Subsidy to owners' organisations or property management companies.

The scheme’s first phase covers private residential and composite buildings, while its second phase covers industrial and commercial buildings.

The ASPM is still open for applications and continues to disburse subsidies.

Prevention of aberrant cutaneous wound repair and appropriate regeneration of an intact and functional integument require the coordinated timing of fibroblast and keratinocyte migration. Here, we identified a mechanism whereby opposing cell-specific motogenic functions of a multifunctional intracellular and extracellular protein, the receptor for hyaluronan-mediated motility (RHAMM), coordinates fibroblast and keratinocyte migration speed and ensures appropriate timing of excisional wound closure. We found that, unlike in WT mice, in Rhamm-null mice, keratinocyte migration initiates prematurely in the excisional wounds, resulting in wounds that have re-surfaced before the formation of normal granulation tissue, leading to a defective epidermal architecture. We also noted aberrant keratinocyte and fibroblast migration in the Rhamm-null mice, indicating that RHAMM suppresses keratinocyte motility but increases fibroblast motility. This cell context–dependent effect resulted from cell-specific regulation of extracellular signal-regulated kinase 1/2 (ERK1/2) activation and expression of a RHAMM target gene encoding matrix metalloprotease 9 (MMP-9). In fibroblasts, RHAMM promoted ERK1/2 activation and MMP-9 expression, whereas in keratinocytes, RHAMM suppressed these activities. In keratinocytes, loss of RHAMM function or expression promoted epidermal growth factor receptor–regulated MMP-9 expression via ERK1/2, which resulted in cleavage of the ectodomain of the RHAMM partner protein CD44 and thereby increased keratinocyte motility. These results identify RHAMM as a key factor that integrates the timing of wound repair by controlling cell migration.

Although a robust inflammatory response is needed to combat infection, this response must ultimately be terminated to prevent chronic inflammation. One mechanism that terminates inflammatory signaling is the production of alternative mRNA splice forms in the Toll-like receptor (TLR) signaling pathway. Whereas most genes in the TLR pathway encode positive mediators of inflammatory signaling, several, including that encoding the MyD88 signaling adaptor, also produce alternative spliced mRNA isoforms that encode dominant-negative inhibitors of the response. Production of these negatively acting alternatively spliced isoforms is induced by stimulation with the TLR4 agonist lipopolysaccharide (LPS); thus, this alternative pre-mRNA splicing represents a negative feedback loop that terminates TLR signaling and prevents chronic inflammation. In the current study, we investigated the mechanisms regulating the LPS-induced alternative pre-mRNA splicing of the MyD88 transcript in murine macrophages. We found that 1) the induction of the alternatively spliced MyD88 form is due to alternative pre-mRNA splicing and not caused by another RNA regulatory mechanism, 2) MyD88 splicing is regulated by both the MyD88- and TRIF-dependent arms of the TLR signaling pathway, 3) MyD88 splicing is regulated by the NF-κB transcription factor, and 4) NF-κB likely regulates MyD88 alternative pre-mRNA splicing per se rather than regulating splicing indirectly by altering MyD88 transcription. We conclude that alternative splicing of MyD88 may provide a sensitive mechanism that ensures robust termination of inflammation for tissue repair and restoration of normal tissue homeostasis once an infection is controlled.

Bacterial products such as lipopolysaccharides (or endotoxin) cause systemic inflammation, resulting in a substantial global health burden. The onset, progression, and resolution of the inflammatory response to endotoxin are usually tightly controlled to avoid chronic inflammation. Members of the NF-κB family of transcription factors are key drivers of inflammation that activate sets of genes in response to inflammatory signals. Such responses are typically short-lived and can be suppressed by proteins that act post-translationally, such as the SOCS (suppressor of cytokine signaling) family. Less is known about direct transcriptional regulation of these responses, however. Here, using a combination of in vitro approaches and in vivo animal models, we show that endotoxin treatment induced expression of the well-characterized transcriptional repressor Krüppel-like factor 3 (KLF3), which, in turn, directly repressed the expression of the NF-κB family member RELA/p65. We also observed that KLF3-deficient mice were hypersensitive to endotoxin and exhibited elevated levels of circulating Ly6C+ monocytes and macrophage-derived inflammatory cytokines. These findings reveal that KLF3 is a fundamental suppressor that operates as a feedback inhibitor of RELA/p65 and may be important in facilitating the resolution of inflammation.

Antibodies are widely used as cancer therapeutics, but their current use is limited by the low number of antigens restricted to cancer cells. A receptor tyrosine kinase, receptor tyrosine kinase-like orphan receptor 2 (ROR2), is normally expressed only during embryogenesis and is tightly down-regulated in postnatal healthy tissues. However, it is up-regulated in a diverse set of hematologic and solid malignancies, thus ROR2 represents a candidate antigen for antibody-based cancer therapy. Here we describe the affinity maturation and humanization of a rabbit mAb that binds human and mouse ROR2 but not human ROR1 or other human cell-surface antigens. Co-crystallization of the parental rabbit mAb in complex with the human ROR2 kringle domain (hROR2-Kr) guided affinity maturation by heavy-chain complementarity-determining region 3 (HCDR3)-focused mutagenesis and selection. The affinity-matured rabbit mAb was then humanized by complementarity-determining region (CDR) grafting and framework fine tuning and again co-crystallized with hROR2-Kr. We show that the affinity-matured and humanized mAb retains strong affinity and specificity to ROR2 and, following conversion to a T cell–engaging bispecific antibody, has potent cytotoxicity toward ROR2-expressing cells. We anticipate that this humanized affinity-matured mAb will find application for antibody-based cancer therapy of ROR2-expressing neoplasms.

(University of Cambridge) Parents should not feel pressured to make their young children undertake structured learning or achieve specific tasks, particularly during lockdown. A new study of children under the age of two has found that parents who take a more flexible approach to their child's learning can - for children who were easy babies - minimise behavioural problems during toddlerhood.

The Government today announced that applications are open for several support schemes following the funding approval of the second round of the Anti-epidemic Fund and other relief measures by the Legislative Council Finance Committee.

The Club-house Subsidy Scheme, which provides a one-off subsidy of $100,000 to eligible club-houses, is now open for application. The deadline for application is May 18.

Upon submission of the completed application form and supporting documents, the disbursement of subsidies could generally be made in around two weeks.

The Travel Agents & Practitioners Support Scheme and the Hotel Sector Support Scheme are also open for applications, with the deadlines on June 15 and May 18 respectively.

The Subsidy Scheme for the Refuse Transfer Station Account Holders for Transporting Municipal Solid Waste, which offers a one-off subsidy of $8,000 to each of the eligible private municipal solid waste collectors operating in the first quarter, was also endorsed.

To ease the application procedures, the Environmental Protection Department will post cheques to recipients of this special subsidy in about a week after the funding endorsement.

Meanwhile, the total guarantee commitment of the Special 100% Loan Guarantee under the SME Financing Guarantee Scheme has been increased to $50 billion.

The maximum loan amount per enterprise has been increased to $4 million and the principal moratorium arrangement has been extended to the first 12 months.

The Special 100% Loan Guarantee will start receiving applications from April 20 and the application period has been extended to one year.

In March, Hong Kong International Airport (HKIA) became the first in the world to be certified as an International Air Transport Association (IATA) Center of Excellence for Perishable Logistics (CEIV Fresh) Partner Airport.

Two of the airport’s cargo terminal operators, Hong Kong Air Cargo Terminals Limited (HACTL) and Cathay Pacific Services Limited (CPSL) have achieved IATA CEIV Fresh Certification, while Cathay Pacific recently became the world’s first airline to be certified.

IATA created the Centre of Excellence for Independent Validators (CEIV) to help organisations involved in the air cargo supply chain achieve handling excellence.

The certification underscores the speed, consistency and efficiency of all HKIA stakeholders when it comes to the treatment and transportation of perishable products.

It also helps to ensure food safety, and reduce food wastage and loss along the supply chain.

Quality benchmark

Hong Kong Air Cargo Terminals Limited Chief Executive Wilson Kwong said the main value of the accreditation is that it provides a universally recognised standard.

“It gives assurance to the various stakeholders that we have, and we are adhering to the highest possible standards.”

Both accredited cargo terminal operators HACTL and CPSL have set up perishable cargo handling areas with truck docks next to the apron.

As soon as the perishable goods are unloaded from the aircraft, they are immediately transported to the handling area.

The clearance and sampling checks have been streamlined to minimise the time taken to unload the goods. There are cold rooms set at tailored temperatures for various kinds of perishable cargo.

Their staff training and handling process have also been assessed and certified for their compliance with the global industry standards.

Cathay Pacific Services Limited Chief Executive Officer Jenny Lam noted that one of the challenges in meeting the certification standard is training its 2,000 employees in handling and storing perishable goods.

“They first have to identify what types of perishables they are, such as are they flowers, are they fruits, are they meat, so that they know how to segregate the storage.

“Secondly, they gain knowledge about certain fruits that cannot be put close to each other such as bananas and apples.”

Growth opportunities

In 2018, the airport handled about 380,000 tonnes of perishable cargo - a rise of 12% on 2017, with perishables accounting for about 8% of total air cargo volume.

Airport Authority Commercial Executive Director Cissy Chan explained that temperature-controlled air freight is one of the fastest growing segments in the air cargo market.

She believes with the new certification, the airport is well-placed to capture the increasing growth opportunities in the market for fresh and perishable goods.

“With the opening of the Hong Kong-Zhuhai-Macao Bridge, the transport time between the airport and the Greater Bay Area, notably the western part of the Pearl River Delta, will be further cut down.

“So this will put us in an even better position to become the transhipment hub for these perishables for the entire bay area.”

Extra backing

To support the growing demand for perishables, the Airport Authority has provided additional cool dollies, so there are now more than 30 for use by the whole airport community. It is also building apron shelters to protect the perishables from ambient weather elements.

Cathay Pacific Cargo Service Delivery General Manager Frosti Lau said they would work closely with the authority and its cargo terminal to see what new investments are required to handle the increasing demand.

Residents may have seen a distinctive white car, fitted with advanced imaging and sensory gadgetry, on its journey to create the next generation of Hong Kong maps.

As it travels up and down the city’s streets, it records the three-dimensional shapes of buildings ranging from the iconic Convention & Exhibition Centre to the Customs Headquarters Building, and even primary school campuses.

The vehicle, dubbed the Mobile Mapping System, is one of the latest technologies used by the Lands Department to survey the city.

Five pieces of equipment work in concert to collect detailed information for the 3D City Map - a core component of the digital infrastructure underpinning Hong Kong’s smart city development.

A high-resolution camera on top of the vehicle captures 360-degree images and a 3D laser scanner collects spatial measurements. An inertial navigation system and a global navigation satellite system receiver provide precise positioning.

Lands Department Assistant Land Surveyor Charlie Hung said one of the biggest advantages of this system is its ability to quickly and efficiently acquire data, which can be used to enrich 3D models and enhance existing maps.

“We can enhance the attributed information of our basic map. For example, the lamppost number, the building name or the street number.”

Drones are also used to map the city, she added. However, air surveying may not be suitable for collecting data from ground level. This is where the Mobile Mapping System vehicle comes into play.

Better data

The 3D City Map is part of the 3D Digital Map Development, which aims to contribute to an innovative, sustainable and smart Hong Kong.

Compared with traditional maps, the 3D City Map can provide more accurate and abundantly better spatial data.

The map will cover the entire city by 2023, serving as a handy tool for analysis and planning, according to Lands Department Land Surveyor Ben Fan.

He said: “Based on the 3D digital map, we can develop various kinds of applications such as land administration, environmental assessment, town planning and also transport and engineering studies.”

The latest transport infrastructures such as the Hong Kong-Zhuhai-Macao Bridge, the Central-Wan Chai Bypass and the Heung Yuen Wai Highway have also been scanned.

In the next stage of the 3D Digital Map Development, the department will create the 3D Indoor Map. As a start, data from 150 buildings in Kowloon East will be collected first before extending to other buildings in the city.

The last stage 3D models of objects such as trees and lampposts for city modelling will be produced.
