This paper analyzes the spatial representations constructed by reality, filming, and narrative in the works of Hong Kong film director Wong Kar-wai, and how these spaces influence Hong Kong's urban culture, perception, and interpersonal relationships. To analyze Wong Kar-wai's films, Charles Sanders Peirce's semiotics concepts and Paul Virilio's spatial concepts were applied. Through this, we examined how the meaning embedded in the spatial representations of Wong Kar-wai's films could become a crucial factor in their success. Wong Kar-wai focused on the values of human relationships formed by society in his subject expression, directly representing the human inner world and prompting audiences to think about it. In this paper, we categorized the spaces depicted in Wong Kar-wai's films as public, private, and connective spaces, and analyzed them as a means to show the living environment and emotions of Hong Kong's youth. Through this, we determined that the spatial representations in Wong Kar-wai's films effectively demonstrate the cultural interpretation function of Hong Kong's citizen consciousness at the junction of Eastern and Western cultures and social connections. In conclusion, Wong Kar-wai's works provide a rich understanding of contemporary people's lives, emotions, and urban spaces, offering valuable insights into Hong Kong's film industry and cultural values.

As S. Korea is becoming an "aged society", workers in the country would be exposed to higher risk of workplace injuries due to their reducing work abilities as they are getting old. To identify the relationship between the work ability and the incident rate of workplace injuries, the work ability index (WAI) scores were surveyed from 409 workers occupied in different manufacturing industries reside on north GyoengBuk area. The workplace injury statistics in the year of 2010 for the corresponding industries were analyzed and summarized with the WAI scores by age groups, years of service, and sizes of business. The results showed the WAI scores of the workers occupied in the higher risk of workplace injury was lower than that of the workers of the lower risk. It means the lower the WAI score, the higher the chance of being injured during the task. It is concluded that appropriate correlation exists between the WAI scores of workers and the incident rate of workplace injury. It is recommended to administrate individual work abilities of aged workers in order to keep low rate of workplace injuries in upcoming aged and highly aged society.

The population over 65 years of age in Korea will be 10.3% of the entire population in 2008 indicating that Korea is already in an aging society. In addition, it is expected that Korea will be in an aged society in 2018 (population over 65 years of age : 14.3%) and that it will be in a post-aged society in 2026 (20.8%). Consequently, aged workers may also increase. It is well-known that the possibility to work longer and to live better is highly related to the work ability of individual. The objective of this study was to evaluate the work ability of each age group using the Work Ability Index(WAI) in the shipbuilding industry, and to assess the effects of social psychological stress, drinking characteristics, smoking characteristics, etc. on the WAI score. The results showed no significant difference on the effects of aging, drinking, and smoking characteristics. Interestingly, a statistical analysis on the effects of social psychological stress revealed a significant difference by stress levels. The difference of the average WAI score between the healthy group and the high risk group was about 10 points. Based on this result, it can be concluded that the stress level is an influential factor on WAI.

Background: This study was to identify the effects of blood flow restriction on gluteus muscles thickness, density, and white area index for children with cerebral palsy. Design: Randomized controlled trial. Methods: Twenty children with cerebral palsy were assigned randomly to an experimental (n=10) or control (n=10) group. The experimental group performed a bicycle exercise after blood flow restriction. The control group performed a bicycle exercise. The study used an ultrasonic instrument to measure gluteus muscles thickness, density, and WAI. Wilcoxon signed ranks test was used for determination of differences before and after treatment, and a Mannn-whitney U test was used for determination of differences between treatment groups. Results: As a result of comparison within groups, the experimental and control group showed significant difference for gluteus muscles thickness, density, and WAI after the experiment (p<0.05). In comparison between two groups, the experimental group showed more significant difference in gluteus muscles thickness, density, and WAI than the control group (p<0.05). Conclusion: Based on these results, a bicycle exercise after blood flow restriction effectively improved the gluteus muscles thickness, density, and WAI of children with cerebral palsy.

Background: Work Ability Index (WAI) is a well-known and valid self-report tool that has been widely used in various studies to identify and avoid early retirement and work-related disability. Nevertheless, very few studies have been carried out to evaluate work ability in Iran. We aimed to investigate the WAI and the effect of work-related stress on it among Iranian workers. Methods: A cross-sectional, descriptive and analytic study was carried out among 449 workers from five working sectors in three big cities of Iran. Work ability and work-related stress were measured using the Persian version of WAI and the Persian version of Health and Safety Executive Stress Indicator Tool. Results: More than a third of the workers surveyed (34.70%) did not have an appropriate level of work ability (WAI < 37). There was a significant correlation between subscales of work-related stress and the mean score of WAI. Furthermore, the variables of body mass index, sleep quality, exercise activity, job tenure, and three subscales of work-related stress including demands, supervisor support, and role were significant predictors of WAI. Conclusion: According to the results of this study, the interventional programs must be focused on improving supervisors support, eliminating ambiguity and conflicts in the role of workers in their job and organization, reducing job demands, improving sleep quality, and increasing exercise activity.

This study aims to comparison of ultrasonography on both sides of the upper arm of hemiplegic patient. The biceps brachii and deltoid muscle of ten subjects(4 men, 6 women) with stroke were scanned with ultrasonography at the muscle belly at rest at elbow angles of 90 deg. The echogenicity(densit, white area index; WAI) and muscle thickness of ultrasonography was examined using real-time B-mode ultrasonography with 7.5 MHz linear-array prob. In the biceps brachii muscle, MHz there were significant differences of thickness, density, and WAI between affected side and non-affected side. In the deltoid muscle, there were significant differences of thickness, density, and WAI between affected side and non-affected side. Both of the muscles, thickness of the affected side was thin than non-affected side and echogenicity(density, WAI) of the affected side was higher than non-affected side. This study showed that change of skeletal muscle architecture properties occurred in the upper arm of the affected side muscle of hemiplegic patient.

According to the Korea National Statistical Office data in 2008, the population over ages of 65 years would possess to 10.7% whole population of Korea in 2009 denoting Korea is already in the aging society. It is well-known that the possibility to work longer and to live better is highly related to the work ability of individuals. The objective of this study is to evaluate the work ability of each aged group using the Work Ability Index(WAI) in the shipbuilding industry, machinery industry and Korea housing corporation, and to assess the effect of the type of business, age and job on the WAI score. The results showed that no significant difference was identified on the effect of aging although work ability of some group(over 55 years) was a little higher than that of others. Also, type of business and job had a significant effect on WAI score. These results suggested that the work ability is not necessarily related to aging in Korean society. One possible explanation for this might be different cultural characteristics of Korean society.

쌀가루 제조 후 입자크기 비율에 따른 품질 특성을 검토하였다. 혼합 쌀가루의 색도를 보면 100-200메쉬 사이의 쌀가루 색도에 있어 자기는 유의성을 보이지 않았고 혼합쌀가루가 습식의 함량이 많을수록 쌀가루의 밝기가 증가됨을 나타내었다. 건식과 습식의 비율에 있어 밝기는 유의성을 나타내었지만 a값과 b값의 경우 혼합비율에 유의성을 나타내지 않았다. 혼합쌀가루 역시 입자크기가 작을수록, 건식쌀가루의 혼합 비율이 높을 수록 수분흡수지수(WAI) 및 수분용해지수(WSI)의 값은 높은 경향을 나타내었다. 80메쉬의 혼합쌀가루는 건식쌀가루의 혼합 비율에 상관없이 거의 같은 WAI의 값을 나타내었고, 100-140메쉬의 혼합쌀가루의 WAI 값이 가장 높은 값을 나타내었다. WAI와 WSI의 값은 각각 쌀가루의 수분함량과는 유의적인 연관성은 없는 것으로 나타났으며 각 쌀가루의 입자의 크기와 건식, 습식쌀가루의 종류와 혼합 비율에 따라 변화가 있는 것으로 나타났다. 입자의 크기에 따른 호화엔탈피의 변화는 200메쉬 이하의 입자 크기에서는 큰 영향을 주지 못했으나 200메쉬 이상에서는 호화엔탈피 값에 차이가 있었다. 혼합쌀가루의 경우 입자가 클수록 전분손상도가 낮게 나왔으며 건식쌀가루의 함량이 높을수록 전분손상도가 높게 나타났다.
