우리나라의 기업들도 조만간에 EDPS의 도입문제에 당면하지 않을 수 없다. EDPS의 도입을 위해서는 전문적인 지식과 경험을 갖고 충분한 사전연구와 긴 준비기간을 요하는 만큼 문제에 직면해서 도입을 서두른다면 이미 늦어버린다. 이 글은 그러한 의미에서 EDPS의 도입 그 자체보다는 도입을 위한 준비단계에서의 기본방향과 원칙을 제시하기 위해서 이 분야에 관심있는 경영자들을 위해 EDPS의 윤곽(outline)과 컴퓨터 시스팀의 기능과 초기단계에서의 교육과 훈련의 중요성을 강조하는데 끝이었다. 따라서 EDPS 도입의 실제와 구체적인 접근방법(approach) 그리고 이에 수반하는 데이터의 정비, 시스팀 분석과 설계, 프로그램 개발 등 기술적이고 전문적인 부분에 대해서는 실무자가 당면하는 문제이므로 주제와 수준을 달리하여 다음 기회에 계속하기로 하고 이 글에서는 생략하였다.

This study aims to examine how the organizational satisfaction affects the desired period of service in the current workplace among young employees. Among detailed organizational satisfaction variables with nine sub-categories, a level of satisfaction with (1) tasks and (2) compensation and recognition policies have a positive effect on the desired period of service in the current workplace. In addition, there is gender difference in the determinants of the desired period of service in the current workplace. For male employees, (1) leadership, (2) tasks and (3) compensation and recognition policies positively affect the desired period of service in the current workplace. For female employees, (1) environment and (2) career and HR training have a positive impact on the desired period of service in the current workplace. Using these results this research suggests implications that how company prevents the outflow of human resource by increasing the desired period of service of young employees.

Twenty male soccer players volunteered as the experimental subjects. The subjects were randomly assigned to the "Winter training with Cornus officinalis extract intake group"(WCI; n=10) and "Winter training group"(WT; n=10). The variables of blood fatigue substance, muscle damage and liver function where measured in all the subjects before the start of the Cornus officinalis intake after at the end of the 4 weeks winter training. Winter training program was proceeded with 6 days a week for 4 weeks. Exercise intensity was measured using the HRR(70~95%). Changes in the heart rate were also measured with the Polar. WCI group were ingested 80 mL of Cornus officinalis extract after every breakfast and dinner for 4 weeks. The test data were analyzed by paired t-test, and independent t-test(%diff), and the alpha level of p<.05 was set for all tests of significance. Lactate in WCI group had significantly decreased, and the changes between the groups were significantly lower in the WCI group than in the WT group. Ammonia in WCI group had significantly increased. CK in WCI group had significantly decreased. LDH in both group had significantly decreased. AST in WCI group had significantly decreased, and the changes between the groups were significantly lower in the WCI group than in the WT group. ALT in WCI group had significantly decreased. In conclusion, the results of this study show that Cornus officinalis extract seem to have a positive influence on blood fatigue substance, muscle damage and liver function. Therefore Cornus officinalis extract is considered to be able to contribute an ergogenic aids.

실업률은 실업의 빈도와 실업기간의 복합체로 결정된다. 따라서 동일한 실업률하에서도 다수의 실업자가 단기실업을 경험할 수 있는 반면, 소수의 실업자가 장기의 실업을 경험할 수도 있다. 실업의 경제비용이란 측면에서 볼 때, 전자의 실업은 부문별 수요변화에 따라 신속한 인력 재배치가 진행됨을 의미하는 반면, 후자의 실업은 구조적인 인력 수급 불균형을 반영하고 있어 높은 경제비용을 수반할 가능성이 높다. 본 논문은 우리나라의 경우 실업률의 지속적인 하락에도 불구하고 1990년대에 들어 실업기간이 장기화되고 있음을 보이고 있다. 이러한 실업 장기화 현상은 노동공급 측면에서 비교적 경제활동이 낮았던 저학력 및 청년, 그리고 여성 근로자층의 구직활동이 적극화된 점과, 노동수요 측면에서는 수요의 고학력화에 따른 장년층 및 저학력 실업자의 구직난을 반영하고 있는 것으로 평가된다. 이러한 결과는 현 경제위기에서 많은 장기실업자가 발생할 가능성이 높음을 시사하고 있어 실직자 지원의 효율적 확대와 직업훈련 효율성 제고의 필요성이 높다고 사료된다.

Objective : This study was to verify the effects of occupation-based training with errorless learning and spaced retrieval on task learning and satisfaction of elderly with mild vascular dementia. Methods : The subjects of this study were 3 geriatric individuals with mild vascular dementia, ABA' + follow-up design was used. Intervention period was provided occupation-based training with errorless learning and spaced retrieval. The dependent variable was converted to ability of task performance every session and satisfaction before and after intervention. Result analysis was suggested through visual analysis and bar graph. Results : After the occupation-based training with errorless learning and spaced retrieval, Ability of task performance and satisfaction improved for all subjects. Conclusions : From this study, occupation-based training with errorless learning and spaced retrieval training was found to be an effective mediation for improving independence of task and satisfaction for people with mild dementia. This study could provide evidence for clinical application for occupation-based training.

Objective : The purpose of this study was to investigate the effects of task-oriented training with functional electrical stimulation on hand function in incomplete cervical cord injury. Method : The subjects of the study were 3 adults diagnosed as incomplete cervical cord injury. The design of this study was ABA single-subject research design to compare dominant hand function of before and after intervention and detect individual effects. The experiment consisted of 30sessions, in which baseline process A1 and A2 were implemented 5 sessions each for 10sessions. Intervention B was implemented 20 sessions. The dependent variable was converted to the change of hand function every session, and Canadian Occupational Performance Measure (COPM), Jebsen-Taylor Hand Function Test(JTHFT), Wolf Motor Function Test(WMFT) were selected for outcome measurements. Result analysis was suggested through visual analysis using a graph and comparison of pre, post and follow-up intervention measurements. Results : As a result, the quality and quantity of dominant hand function increased during intervention B compared to the baseline A1 for all subjects. Baseline A2 was also maintained without training. Additionally, JTHFT, WMFT and COPM scores demonstrated improvement and maintain. The follow up JTHFT and WMFT showed increased required time on all subjects and decrease or maintain task performance and satisfaction in COPM. Conclusion : The task-oriented training with function electrical stimulation in this study has been positive effects on hand function and task performance and satisfaction.

North Korea's demand for infrastructure construction and maintenance is growing rapidly. On the other hand, the number of skilled workers is insufficient. Therefore, through a survey of North Korean defectors, this study analyzed the status of construction technology and the difficulties of construction workers. In addition, an attempt was made to derive an appropriate education and training program process and operation plan. As a result of the survey, the reason for the low technical level of construction workers was the lack of skills, lack of motivation to work, and the lack of training and management systems. The appropriate education and training period was 56% of the total response within one year and 36% within six months. Based on the results of this survey, the period of education and training for the rapid training of construction technical personnel in North Korea was adopted as one year. Moreover, compared to the NCS standard in South Korea, appropriate training hours were suggested, excluding training courses, such as planning and design, construction management that require specialized knowledge. Finally, the curriculum corresponding to the education and training courses and the standards for facility names and required areas for facility operation were suggested.

Purpose: This study evaluates the effectiveness of intermittent exotropia vision training through follow up of average 3 years using proprioceptive test (Maindot test). Methods: 35 people (18 men, 17 women) with mean age of 13.48 (${\pm}2.45$) with corrected visual acuity of 0.9 or higher and normal binocular vision and control were observed for changes between before, after, and 3 years following the vision training during the period from 2005 to 2009. Results: After training, the correlation between the changed amount of deviation and PRC(diplopia) value and symptoms was not significant (p>0.05). However, it showed a statistically significant (p<0.001) correlation that change of the binocular proprioceptive sense abilities is decreased subjective symptoms. Conclusions: Binocular proprioceptive sense may be used in variety of purposes and applications such as predictive evaluation of binocular symptoms, binocular function performance evaluation after vision training and prism treatment.
