This paper analyzes how IT adoption affects differently on the shippers' make-buy decision, depending on the changes through agency and coordination problems. Empirical findings are consistent with the theoretical predictions on the changes of shippers' decision, summarized as follows. First, while the adoption of agency-cost reducing IT leads to the increase in the proportion of private fleets, the adoption of coordination-cost reducing IT leads to the increase in proportion of for-hire carriage. Second, the extent of private fleets changes depends on the primary product type that trucks load, with products of important service task experiencing more increase. Third, the extent of for-hire carriage changes depends on the truck's trip distance, with long-trip trucks experiencing more increase. With the results, we present different policy implications from the conventionally advocated ones.

This study was done in order to analyze the factors which influenced the performance level of community health practitioners' task. Interview survey was done during the period from August to October, 1986. Interviewee were 166 CHPs among total of 217 CHPs in Kyonggi province area. Multiple stepwise regression and canonical correlation analysis were used to identify major factors influenced to perform community health practitioners' task. The results of this study were summarized as follows: 1. General characteristics of CHPs 1) Personal characteristics The average age of CHPs was 37.8 years and their marital status was $77.6\%$ of married, educational back-ground was $65.3\%$ of junior college graduation. Their job career was $38.6\%$ of between 1-3 years, $33.3\%$ of between 3-5 years, $22.2\%$ of less than 1 years. Most of CHPs$(62.8\%)$ were fully satisfied with their job, $33.3\%$ were moderately, and $3.8\%$ were not satisfied. 2) Working environmental condition Only $31.7%$ of CHPs were satisfied with their working condition of primary health post, $26.6\%$ were not satisfied. Half of CHPs$(52.5\%)$ replied having good cooperation with health center, $10.1\%$ replied bad. Cooperation with health subcenter was good in $32.9\%$, and bad in $21.9%$. Cooperation with private health institutions was good in $34.2\%$, bad in $21.6%$. 2. Performance level of community health practitioners' task Among a total of 52 contents of their functions medical history taking. physical examination, referral of diagnostic laboratory work-up($(86.4\%)$, health assessment of pregnant women$(82.1\%)$, development of health information system$(79.4\%)$, supervision of health workers $(78.4\%)$, follow-up of family planning acceptors$(77.3\%)$, and follow-up of family planning acceptors' side effects$(77.3\%)$ were actively performed. Diagnosis of pregnancy$(62.1\%)$, sampling of drinking water for quality test$(52.5\%)$, making list of equipment' & supplies $(51.5\%)$, evaluation of primary health post activities $(37.6\%)$, organization of village health workers$(32.4\%)$ and management of village health workers $(30.1\%)$ were poorly performed. 3. Stepwise multiple regression analysis of job function The factors which influenced the performance level of community health practitioners' function were age, marital status, educational level, job career, job satisfaction, satisfaction of working environment of primary health post, cooperation of health center, cooperation of health center, cooperation of private health instiutions in orders. These 9 variables were able to explain job function from $25.7\%$ of program planning to $6.7\%$ of management of common disease. 4. Canonical correlation analysis between the performance of function and general characteristics of CHPs. Cooperation of private health institutions was found to be the factor influencing task performance of community organization, management of primary health post, technical supervision of health personnels. Job satisfaction of CHPs was also found to be the factor influencing task performance of family planning, management of common disease and maintenance of health information system.

Purpose : This study was performed to examine the effect of stimulation task-oriented training on the balance ability of the hemiplegic patients caused by stroke. Methods : We made a random sampling of 25 hemiplegic patients caused by stroke. 10 patients(experimental group)were treated by simulation Task-oriented training and Conventional training used by balance pad. The other 10 patients(control group) were only treated by Conventional training used by balance pad. During the training, 3 patients from the experimental group and 2 patients from the control group were excluded by private affairs. The control group has done Conventional training 6 times a week for 6 weeks. And experimental group has done Simulation task-oriented training two times, conventional training four times a week for 6 weeks. Balance ability was assessed by Fuctional Reaching Test (FRT) : unilateral and bilateral reaching. Results : In comparison of FRT before and after training, two groups all was significantly improved(p<.05). But bilateral reaching variation was significantly improved in experimental group. Conclusion : we can use simulation Task-oriented training valuably to increase balance ability of hemiplegic patients.

처리과란 문서의 수발 및 사무처리를 주관하는 부서를 말하며 업무와 기록물생산의 시작점이다. 처리과에서는 기록물을 생산하는 것뿐만아니라 편철·정리·보존기간 책정·이관 등 기록물관리 업무의 대부분을 수행하고 있다. 이러한 처리과 기록물관리의 중요성에도 불구하고 처리과의 기록물관리 문제는 업무담당자들의 의지부족 등 개인적인 문제로 치부되곤 했다. 이 연구는 처리과 기록물관리의 중요성과 업무담당자가 생각하는 기록물관리를 설문조사를 통해 조사한 후, 기관 기록물관리 업무에서 개선해야 할 사항들을 도출하였다.

The impact of supervisory communication apprehension (SCA) on subordinates' job performance was investigated in this study. We also examined the impact of task-related uncertainty in mediating the relationship between SCA and subordinate work performance, as well as the role of information-seeking behavior in moderating the relationship between task-related uncertainty and subordinate job performance. A sample of subordinates and their supervisors from public and private sector enterprises in Pakistan were used in the study. The concept of communication apprehension is not limited to a single organization or industry, and the conditions suggest that apprehensive supervisors are likely to exist in different organizations and industries in Pakistan, including banks, telecommunications, and development sector organizations. Company directors and leaders of human resources departments were contacted to reach out to possible respondents. SmartPLS software was used to evaluate the data using a structural equation modeling technique which is commonly used in explanatory studies (Atta et al., 2021). We found evidence to support ideas predicting the association between SCA and subordinate job performance, as well as the mediating role of task-related ambiguity in the relationship. Furthermore, the findings show that information-seeking activity has a moderating effect on the link between task-related ambiguity and subordinate job performance. This is one of the first studies to look at major mediating and moderating mechanisms in the link between SCA and subordinate job performance.

버스 분할 기법은 통신이 많은 모듈들을 가까이 배치하고 필요한 버스 단편만 사용함으로 버스 에너지 소비를 줄인다. 그러나 MPSoC와 같은 다중 프로세서 플랫폼에서는 캐시 일관성을 유지하기 위하여 모든 프로세서에서 버스 트랜잭션을 알아야 하므로, 기존의 버스 분할 기법을 적용할 수 없다. 본 논문에서는 공유 메모리 기반의 MPSoC 플랫폼에서 버스 에너지를 절감시키기 위한 버스 분할 기법을 제안한다. 제안된 버스 분할 기법은 비 공유 메모리와 공유 메모리의 버스를 분할함으로써, 캐시 일관성을 유지하며 비 공유 메모리를 참조할 때 소비하는 버스 에너지를 최소화시킨다. 또한, 태스크별 버스 트랜잭션 횟수를 기반하여 태스크를 할당함으로써, 공유 메모리를 참조할 때 소비하는 버스 에너지를 절감시키는 캐시 일관성을 고려한 태스크 할당 기법을 제안한다. 시뮬레이션을 통한 실험에서 제안된 버스 분할 기법은 비 공유 메모리 참조시의 버스 에너지를 최대 83%까지 절감시키며, 태스크 할당 알고리즘은 공유 메모리 참조시의 버스 에너지를 최대 36%까지 절감시키는 효과가 있음을 보여준다. 그럼으로 다중 프로세서 시스템에서도 버스 분할 기법을 적용하여 버스 에너지 절감 효과를 볼 수 있으며, 캐시 일관성을 고려한 태스크 할당 기법을 통해 추가적으로 버스 에너지를 절감할 수 있음을 보여준다.

A private company's 1,000 MW coal-fired power plant will be the first coal-fired power plant that was included in the 5th 'Basic Plan on Electricity Demand and Supply' (2010). Now it is facing the task to abide by the RPS(Renewable Portfolio Standard) policy after commercial operation. If they fail to supply the necessary REC (Renewable Energy Certificate) mandated by the RPS policy, they are subject to be fined by the government and forced to modify the cost function to reflect the burden. Eventually the company's coal-fired power plant will be forced to reduce generation to maximize profit because the amount of electricity generated by the power plant and the REC obligation is positively correlated. This paper analyzed the change of cost function of private coal-fired power plant according to the introduction of RPS policy from the viewpoint of private company, and finally proposed the optimal generation to maximize the profit of private coal-fired power plant under the current RPS policy.
