1950년대 홍콩 영화를 통해 본 5·4 전통의 계승과 변화의 홍콩문화 읽기

Leung, Ping-Kwan,고혜림(번역자) 부산대학교 인문학연구소 2008 코기토 Vol.- No.63

Since 1960’s, the film market of Hong Kong imported funds and human resources from Asia and aimed at Asian film market. Hong Kong originally succeeded the tradition of 1949’s cultural revolution and made it possible to reform and create the whole new changes. This situation was to contribute to effective interactions in the boundary of Asia. But at first there were much more movies to concentrate on conventional ideal, one of which was ‘People exist for me, and I exist for them.’ Hong Kong society focused on its tradition and education as well. If it is the point that we emphasize Hong Kong film, it becomes much more important to mention ‘dramatization.’ And this is the key point to research the changes and the way of change to dramatize the novels into film, then, at the same time, we can understand and figure out the far more complex and tangled history of cultural identity. How this could be possible to make Hong Kong to change other cultures into his own culture and helped to interchange each other their own cultural differences, and how it tried to analyze the differences and sameness? Through this research of Hong Kong film, we will understand Hong Kong culture and its film history. The film market has kept challenging and trying to make big plant and production centers to develop its film. It is no more than simply the action movies and entertainment of public but is a genre of art. Hopefully, the film of Hong Kong will be emerged in Asian film market as well as in the global market.

Research on Traditional Chinese Medicine harmonising two approaches

Leung Ping Chung,Lau Tai Wai,Woo Kam Sang 경희대학교 융합한의과학연구소 2008 Oriental Pharmacy and Experimental Medicine Vol.8 No.1

While full recognition of the practical value of Traditional Chinese Medicine is being endorsed, the current stand on the research methodology of this field should be worked out. Since modern medicine has already developed a logical system of research methodology basing on the principles of deduction, any research on any system of medicine need to take reference to what is most popularly used and commonly recommended. The best way to approach research on Chinese Medicine, therefore, would be one that would take full reference to the methodology being used in modern medicine, while at the same time respecting the traditional approach. This would enable traditional medicine to be elevated to the level of general modern recognition. Nevertheless, innate problems in traditional medicine are making its research difficult. The problems lie in difficulties to achieve uniform herb supply, principles of randomization and placebo arrangements, uncertain chemical structures and toxicology etc. A practical approach centered on carefully planned evidence-based clinical trials, with parallel studies on biological activities and herb authentication is being recommended.

Can herbal extracts be used as skin penetrating agent

Leung Ping Chung,Zhao Xin,Law Wai Tak,Lau Tai Wai David 경희대학교 융합한의과학연구소 2007 Oriental Pharmacy and Experimental Medicine Vol.7 No.3

Swollen and painful extremities have been treated with herbal baths in attempts to alleviate the symptoms. A popular herbal bath used in China, contains a component called ‘bone-penetrating herb’ which is believed to facilitate the penetration of herbal substances across the skin to the swollen site, so that pain and swelling will be improved. A search from the Chinese pharmacopedia revealed that 22 different herbs have been traditionally used as ‘bone-penetrating herb’. Five of these herbs were available in market and were chosen for experimental studies. Standard diffusion experiments were done to identify the most effective herb among the five, in the penetration facilitation. Glechoma longituba at a concentration of 20% was found to give the best results in the facilitation of Bromophenol blue diffusion across artificial and biological membranes. When compared with one commonly used diffusion facilitator, viz. azone, azone was found to be more effective than glechoma longituba. The encouraging observations support future studies on the basic science behind the use of herbal components as topical agents to treat pain and swelling.

Enhancing Teachers' Incorporation of Information and Communication Technologies (ICT) into Classroom Teaching : A Professional Development Strategy

Kin Ping Leung,James J. Watters,Ian Ginns APEC국제교육협력원 2006 Asia-Pacific Cybereducation Journal Vol.2 No.1

Throughout the Asia-Pacific region, despite government efforts to promote the use of information and communication technologies (ICT) in schools, the acceptance and use of these technologies by classroom teachers has been slow to take off. This study focused on ascertaining the effectiveness of a school-based, on-site, and ongoing professional development program conducted in a primary school in Hong Kong. There were training sessions conducted by fellow teachers, and participatory action research groups to share resources and experience in incorporating ICT in teaching. Teachers’ incorporation of computers in teaching was significantly increased in the first year of intervention but showed fluctuation in the second year. A number of explanations for these changes were offered by teachers in their interviews. The lower self-ratings in year two may be due to changes in self-perception rather than changes in actual ability or practices.

Supratentorial Intraparenchymal Haemorrhages during Spine Surgery

Leung, Gilberto Ka Kit,Chan, Johnny Ping Hon The Korean Neurosurgical Society 2014 Journal of Korean neurosurgical society Vol.55 No.2

Intracranial haemorrhages are rare but potentially life-threatening complications of spine surgery. Most reported cases involved subdural or cerebellar haemorrhages; supratentorial parenchymal bleeding is very uncommon. We report a 28-year-old woman who underwent resection of a thoracic Ewing's sarcoma, and developed fatal haemorrhages around her cerebral metastases during surgery. The clinical presentations, possible pathogenesis and potential preventive measures are discussed. Patients with disseminated metastases within the neural axis are at risks of intracranial complications during spine surgery. The presence of intracranial mass lesions should be considered as a relative contraindication to intradural spine surgery.

Ginseng extracts modulate mitochondrial bioenergetics of live cardiomyoblasts: a functional comparison of different extraction solvents

Yun Huang,Kenneth Kin Leung Kwan,Ka Wing Leung,Ping Yao,HuaiyouWang,Tina Tingxia Dong,Karl Wah Keung Tsim 고려인삼학회 2019 Journal of Ginseng Research Vol.43 No.4

Background: The root of Panax ginseng, a member of Araliaceae family, has been used as herbal medicineand functional food in Asia for thousands of years. According to Traditional Chinese medicine, ginseng isthe most widely used “Qi-invigorating” herbs, which provides tonic and preventive effects by resistingoxidative stress, influencing energy metabolism, and improving mitochondrial function. Very few reportshave systematically measured cell mitochondrial bioenergetics after ginseng treatment. Methods: Here, H9C2 cell line, a rat cardiomyoblast, was treated with ginseng extracts having extractedusing solvents of different polarity, i.e., water, 50% ethanol, and 90% ethanol, and subsequently, theoxygen consumption rate in healthy and tert-butyl hydroperoxideetreated live cultures was determinedby Seahorse extracellular flux analyzer. Results: The 90% ethanol extracts of ginseng possessed the strongest antioxidative and tonic activities tomitochondrial respiration and therefore provided the best protective effects to H9C2 cardiomyocytes. Byincreasing the spare respiratory capacity of stressed H9C2 cells up to three-folds of that of healthy cells,the 90% ethanol extracts of ginseng greatly improved the tolerance of myocardial cells to oxidativedamage. Conclusion: These results demonstrated that the low polarity extracts of ginseng could be the bestextract, as compared with others, in regulating the oxygen consumption rate of cultured cardiomyocytesduring mitochondrial respiration.

Placebo Acupuncture in an Acupuncture Clinical Trial. How Good is the Blinding Effect?

Eliza Lai-Yi Wong,Ping-Chung Leung,Lang Zhang 사단법인약침학회 2015 Journal of Acupuncture & Meridian Studies Vol.8 No.1

The purpose of this study was to critically look at the validity of the “placebo procedures” used in acupuncture studies. Twenty healthy volunteers were recruited and blinded either to genuine acupuncture or to “placebo procedures”, and they were checked to ascertain whether they could differentiate genuine punctures from placebo punctures. Each volunteer received paired procedures on three separate occasions. Each paired procedure included one genuine puncture and a placebo procedure. Three placebo procedures, that is, sham points, superficial puncture, and puncturing through a special device, were used. Two standard acupuncture points were used: Hegu (LI-4) in the hand and Zusanli (ST-36) in the leg. Among the 18 participants who completed all three tests, 16 correctly recognized genuine punctures. Sham sites in the hand and the leg were detected by 15 and nine of the participants, respectively. Superficial punctures in the hand and the leg were recognized by 10 and nine of the participants, respectively. A special device, a foam cylinder that hid the distal needle, worked best because 15 and 16 of the participants were deceived when the device was used at an acupoint in the hand and the leg, respectively. No significant differences were noted between those who had had past experience with acupuncture and those who had not. Sham sites and superficial punctures appeared not to have a placebo function because 50–83% of the participants were able to immediately recognize their false nature. Using a hidden device worked much better.
