This study suggest a way to improve duty process of KTX(Korea Train Express) high-speed train driver. A new operating system which based on safety was introduced to operate high-speed train which travel above 300km/h on the high-speed railroad but below 200km/h on the general railroad. There were some studies on the operation of high-speed train which travel on the high-speed railroad and on the general railroad with safety. However they overlooked the elements of human errors. The duty-load of KTX train driver's 14 basic operation processes was measured using NASA-TLX and found four processes with high duty-load. In this paper, critical tasks of the high duty-load processes are determined using a questionnaire. Some suggestions which include the improvement of facilities, operating system and operating skill are proposed to lighten duty-load of the critical tasks. The validity of the proposed new task processes is demonstrated by making question to KTX train driver. To use this results cost-benefit analysis, hazards analysis etc. should be performed additionally.

This exploratory study investigated the software programs utilized by clinical dietitians and their perceptions on the use of information technology. The study focused on the use of specialized software for dietetics, general software for any office use and the Internet. A self-administered survey was used to collect data from clinical dietitians identified in the Kentucky Dietetic Association Directory 2003-2004. The survey was conducted in March through April, 2004. A total of 22 responses were collected, which yielded a response rate of $68\%$. Findings suggest that computer use has become a routine for optimal clinical practice ; major specialized software programs are used for nutrition assessment, nutrition analysis and menu development. Use of specialized software appears to be unassociated with dietitians' age and years of experience ; however, the associations are indicated between use of specialized software and education level as well as their specialty ; word processing and spreadsheet are the major general software used. Internet is used mainly for information search and communication. Respondents perceived that overall work efficiency and productivity significantly increased with computer use. The complexity of software is the major barrier encountered so training is the most needed support by the department. Strategic promotion on the use of specialized software should be targeted to the management team of the hospitals/facilities.

The limited number of roads and the increasing number of vehicles demand the automatic regulation of overspeed vehicles, illegal vehicles, and overloaded vehicles and the automatic charge calculation depending on the type of the vehicle. To meet such requirements, it is important to remove the shadow of the vehicle as processing and recognizing an image captured by a camera. The shadow of the vehicle is likely to cause misclassification of the vehicle type due to diverse errors and mistakes occurring when detecting geometrical properties of the vehicle. In case that shadows of two different vehicles are overlapped, not only the type of the vehicles may be misclassified but also it is difficult to accurately identify the type of the vehicles. In this paper, we propose a robust algorithm to remove the shadow of a vehicle by calculating the luminance, the chrominance, the gradient density of the cast shadow from information acquired using the image subtraction of the background, and to recognize the substantial vehicle figure. Even when it is hard to detect and split a target vehicle from its shadow as shadows of vehicles are attached to each other, our robust algorithm can detect the vehicle figure only. We implemented our system with a general camera and conducted experiments on various vehicles on general roads to find out our vehicle shade removal algorithm is efficient when detecting and recognizing vehicles.

The objective of this paper is to clarify the relationship between ICT application and labor productivity in Vietnamese manufacturing firms and connect it with the context of economic restructuring in Vietnam. The study uses data of 3,428 manufacturing firms from the General Statistics Office of Vietnam and regression models. In addition to the general model, the study also runs the models for sub-samples of firms of different production technology levels. Research results show two main points. First, information technology can enhance the labor productivity of Vietnamese manufacturing firms. This is true for both ICT hardware applications, ICT services, ICT software solutions, and employees' ICT skills in firms. Second, manufacturing firms with higher levels of production technology use ICT more effectively and achieve a higher impact on labor productivity. The results confirm that the Vietnamese government can stimulate ICT application and digital transformation in firms, thereby increasing labor productivity and promoting economic restructuring in the direction of shifting from agriculture to industry and from low-tech industries to high-tech ones. The results also provide implications for business managers and policymakers in other developing countries who are adopting the digital economy as a development strategy.

Purpose: This study aims to find the impact of international trade cooperation and distribution on foreign direct investment (FDI). The study also tests the impact of lag variables of trade cooperation and distribution on FDI in the future. Research design, data, and methodology: Autoregressive Distributed Lag model is applied to analyze the impact of chosen variables such as total trade (TRADE), trade openness (OPEN), the exchange rate (EXR), inflation (INF), and gross domestic growth (GDP) on FDI. Quarterly data is collected from Vietnam General Statistic Office, Vietnam General Department of Customs, International Monetary Fund, and The World Bank from 2006 to 2020. Stata 14 software is used to analyze the regression and test variables. Results: The findings indicate that TRADE, OPEN, INF, GDP, and their lags affect both positively and negatively on FDI in different periods. While OPEN still expresses an unclear impact on FDI. Moreover, this study proves that the FDI of a nation is influenced by international cooperation. Conclusions: This study indicates the importance of international trade cooperation and distribution in not only attracting foreign investment sources but also developing the economy. Findings are necessary bases for governments or authorities in signing international trade agreements in the future.

Immediately after liberation, Shin Kwang-ryul served as the director of the Shinbukcheong People's General Hospital, and defected to South Korea alone in December 1945 with hostility to the Soviet military government. Later, he joined the political operation team (政治工作隊) and was dispatched to the Sinbuk Office as a member of Hamgyeong-do's committee. However, after this was revealed, his wife was taken to the security and tortured to death. Later, when he learned about this, he left a Wolnam Yuseo (越南遺書) and decided to commit suicide. He left politics and started a new family while running a pharmacy. In 1950, he fled Dangjin, Chungnam, during the Korean War and opened an East Asian medical clinic. In 1955, he passed the Korean Medical Examination and opened Cheongpa Oriental Medicine Clinic in Asan, Chungcheongnam-do. In 1969, he ran an East Asian medical clinic in Dohwa-dong, Mapo, Seoul, and moved to Hongeun-dong in 1972 to open Hamnam Oriental Clinic. At this time he wrote a Cheongpa Pharmacy Summary (靑坡驗方要訣). In his later years, he treated poor patients for free, and he continued to work even though he was unwell due to a broken spine. He died in 1980 leaving behind a "proud mind".

Objectives : To investigate the related factors on musculoskeletal symptoms among Korean female workers. Methods : A total of 1,875 female workers (1,002 office workers and 873 blue-collar workers) was analyzed. They were randomly selected among female workers by cluster sampling and interviewed by well trained interviewer, who filled out a structured questionnaire on the musculoskeletal symptoms. Other factors such as general and occupational characteristics including workplace location, employment condition, work duration, and working condition were also investigated. Results : Current smokers and drinkers were significantly more common in blue-collar workers than in office workers. Those working full time were significantly more common in blue-collar workers than in office workers. Those working over 8 hours per day were also popular in office workers than in blue-collar workers. Subjective musculoskeletal symptoms were significantly higher in the type of work including excessive repetitive work, work using awkward stretching hand upwards, work using repetitive wrist movements, static work using awkward hand posture, and heavy manual lifting and handling works. The mean score of the symptoms were significantly higher in blue-collar than in office workers. The significantly different working factors between two groups were work duration, employment condition and daily work hours. Conclusion : We suggest that the type of work including awkward and repetitive works as well as job type may be one of the most important factors related to musculoskeletal symptoms of female workers in the workplace. Preventive strategy will be needed to prevent the negative impact on health status of working women in the workplace.
