Objectives: To find out from an analysis of empirical data the levels of influence, which a labor union (LU) and Occupational Safety and Health Committee (OSHC) have in reducing the occupational injury and illness rate (OIIR) through their accident prevention activities in manufacturing industries with five or more employees. Methods: The empirical data used in this study are the Occupational Safety and Health Tendency survey data, Occupational Accident Compensation data and labor productivity and sales data for the years 2003 to 2007. By matching these three sources of data, a final data set (n = 280) was developed and analyzed using SPSS version 18 (SPSS Inc., Chicago, IL, USA). Results: It was found that a workplace with a LU has a lower OIIR than one without a LU. In manufacturing industries with five or more employees in 2007, the OIIR of the workplaces without a LU was 0.87%, while that of workplaces with a LU was much lower at 0.45%. In addition, workplaces with an established OSHC had a lower OIIR than those without an OSHC. Conclusion: It was found that the OIIR of workplaces with a LU is lower than those without a LU. Moreover, those with the OSHC usually had a lower OIIR than those without. The workplace OIIR may have an impact on management performance because the rate is negatively correlated with labor productivity and sales. In the long run, the OIIR of workplaces will be reduced when workers and employers join forces and recognize that the safety and health activities of the workplace are necessary, not only for securing the health rights of the workers, but also for raising labor productivity.

The banking system provides a number of important functions for the economy and is also the lifeblood and financier of the economy in each country. Large amounts of idle money have not been exploited by banks; however, banks still depend on loans, including loans from foreign banks, to meet the growing demand, as such, for banks, the cost of capital is high, the stability and business efficiency are low and banks have not promoted their internal resources to grow steadily. To achieve the goal, this research analyzes the factors affecting the choice of bank for the deposit decisions of customers in Vietnam. The study used a sample data of 250 individuals and SPSS software was used to analyze the data. The results showed that customer policy has a positive effect on customers' deposit decisions in a bank, and this is new evidence regarding behavioral theory in the case of Vietnam. Results further demonstrated that other factors such as employee image, brand, interest rate, relative influencing, and transaction time positively impact the choice of bank for the deposit decisions of customers. However, the bank's promotion strategies had no impact on the choice of bank for the deposit decisions of customers. Besides, employee image is the most influential factor in the deposit decisions, followed by the bank's brand and interest rate.

The reason that compulsory removals of a low-quality housing redevelopment such as involuntary or unintentional migration present a problem for urban communities is that whether involuntary movers adapt themselves to their new home has an influence on the urban communities that surround them. Moreover, involuntary emigrants have higher probability of choosing faulty residential areas than voluntary emigrants do. This gives rise to a problem of another residential migration for involuntary movers. In order to solve these problems, there is a need for a new housing policy that enables original residents to come back to their old community. However studies for resettlement had not conducted subjects about housing redevelopment characteristics which influences the involuntary movers directly. Instead personal microscopic characteristics such as statistics of resettlement, the moving distance, the reason of moving, improvement of living environment, had been main subjects of farmer studies. So the purpose of this study is to analyze an analysis of the relationship between resettlement and housing redevelopment characteristics. The data used in this study was obtained at 47 areas designated by Seoul (metropolis) since 1990 for redevelopment. Cluster Analysis Is used for dividing high rate of resettlement with low rate of resettlement and Regression Analysis is used for the analysis of the relationship between resettlement and housing redevelopment characteristics. The results of examining the effects of a redeveloped housing complex on returning residents at 47 areas designated by Seoul (metropolis) since 1990 fur redevelopment are as follows: First, A housing complex with a high returning rate (remove-in rate?) has no state/public land, unauthorized building owners who are in the low-income brackets, and few interested parties such as union members. This is the characteristic of a redeveloped housing complex with a short-period project span. On the contrary, a housing complex that has a low returning rate is crowded by state/public land, and numerous unauthorized building owners, and interested parties. Second, According to the linear regression analysis, among the factors that affect returning residents, 'physical properties(characteristics) of a region', 'population properties within a region', and 'properties of a project span' indicate a negative(-)influence whereas 'properties of a complex density' shows a positive(+) influence. In a nutshell, the more the physical properties, population properties, projectspan properties, the lower the returning rate and the more the complex density properties, the higher the returning rate. In detail, an area with many small land and new/large buildings, a high population, and a long project duration has a low returning rate of original residents while an area holding large capacity and buildings with many number of floors (multiple-storied building) has a high returning rate.

Failure of replantation is inevitable in finger replantation surgery, around 10% of failure rate are reported in many authors. Management of the failed finger replantation is one of big dilemma to microsurgeons. We report 5 cases of thumb reconstruction after failure of replantation. The reconstructive surgery composed with early debridement of soft tissue that are under gangrenous processing, extract the phalangeal bone without any soft tissues. Osteosynthesis of the extracted phalangeal bone with host phalangeal bone. The exposed bony portion covered with vascularized flaps such as revered radial forearm pedicled flap, free radial forearm flap and neurovascular island finger flap. This procedure underwent within a week after vascular insufficiency developed. All of the flaps are survived, bone union achieved within 3 months. The function and external appearance of the reconstructed thumb were encouraging; Pinch Power was average 1.2 Pounds. Early removal of necrotizing soft tissue followed by covering none vascular phalangeal bone which extracted from the dead phalanx with vascularized flap is one of the useful alterative solutions in failed replantation surgery in hand.

Arthrodesis of the ankle joint is inevitable in the cases of severe arthrosis or defective bony structures around ankle joint. There have been many kinds of arthrodesis methods were introduced. In cases with failed athrodesis with previous arthrodesis surgery and neuropathic joints have difficulty to achieve fusion of joint with conventional methods. Authors underwent four cases of ankle fusion with vascularized fibular graft from 1997 in the cases of three failed fusions and one diabetic neuropatic joint. Two of four performed free vascularized fibular transplantation from contralateral side leg with microvascular anastomosis, two of four performed with pedicled fibular transposition to the ankle joint in same side leg. Three of four cases achieved arthrodesis average 9.2 months after surgery, one case was failed due to vascular thrombosis of the anastomosed site in diabetic neuropathic condition. The result of this technique revealed 75%(three of four) success rate and longer bone union time required. However, in these cases had no recommendable options with conventional bone graft and additional ankle joint fusions procedure because of poor bone quality and defect of distal tibia and talus portions. Free vascualrized fibular transfer to the failed athrodesis of ankle joint is one of the effective alternative methods in failed ankle fusion cases, especially the quality of the bone around previous fusion site is poor.

After the 1970s, the importance of underground transmission systems increased and the construction rate of underground transmission lines also showed increasing trends each year, especially in metropolitan areas. Accordingly the social ripple effects are very large and wide when the fault occurs in underground power system, and the amount of time and money spent to restore the system also increases. So we must ensure stable operation and long-term reliability of the facilities. In Korea's case, long-term reliability tests for EHV power cables and accessories progressed poorly because equipment was not compatible for long-term reliability tests. Therefore we planned to construct a long-term reliability test field for EHV underground cables in order to ensure international quality reliability and optimal power cable operation techniques. The Gochang Underground Cable Test Field is under construction, funded by the Korean government, the govenment's union investment department, KEPCO, KERI and three private cable corporations. This project began in March, 2005 and will be completed by February, 2010. It is designed to promote joint research by incorporating several types of test equipment, construction of operating facilities, and being an internationally certified authority.

H.264/AVC는 부호화 효율을 크게 향상시킨 비디오 부호화에 대한 표준이다. ITU-T와 MPEG는 가변블록의 움직임, 다중참조화면, l/4 화소 움직임 추정/보상기법과 비트율-왜곡 최적화 기법 등 다양하고 복잡한 부호화 기법들을 적용했다. H.264 참조 모델은 비트율-왜곡 최적화 기법에 기반을 둔 복잡한 부호화 모드 결정 기법을 채택했는데, 이는 부호화기의 높은 복잡성을 요구한다. 본 논문에서는 매크로 블록 부호화 모드의 순서에 대한 비트율-왜곡의 비용 값의 분포에 기초한 효율적인 부호화 모드 결정 기법을 제안하였다. 실험결과는 제안한 방법이 부호화 시간에 있어 34%를 감소시켰으며, 비트율-왜곡의 계산 량을 82% 줄였음을 보여준다.
