매체와 양식, 기술과 표현 사이의 고정관념에서 벗어나는 창작의 본질을 추구하는 창의적 실험을 위한 노력은 미술과 사진을 기반으로 20세기 초반 이후 끊임없이 이어져 왔다. 새로운 표현을 위한 예술적 시도로서 포토몽타주는 탄생했다. 본질적으로 다른 이미지들의 결합으로 새로운 의미를 만들어내는 작업으로서 포토몽타주는 의도적으로 선택한 다양한 이미지를 조합하고 합성하는 방식으로 메시지를 강조하여 시각적으로 구성된다. 이미지와 텍스트의 변증법적 시각예술로서 기존의 예술적 개념을 벗어나 새로운 형식을 추구하며 발전해온 포토몽타주는 그 개념이 현대의 다원예술과 유사하다. 포토몽타주의 가치는 사진의 표현영역을 사실의 묘사와 재현에 국한하지 않고 상상력을 자유롭게 표현할 수 있는 데포르마시옹으로서 새로운 가능성을 모색하고 일상의 경험을 창의적으로 표현하는 작업을 위한 기법의 구현에 있다.

Competitiveness of small and medium companies often rely on the competency of their employees. Many employees however try to move to better environments if possible, which results in high uncertainty in maintaining solid human resources. The purpose of this paper is to investigate the influencing factors of turnover intention and organizational loyalty of the early experienced, especially three to five years experienced, employees in the small and medium enterprises. A survey had been conducted using both LMX (Leader Member eXchange) and TMX (Team Member eXchange) as an effort to test the impact of strategic human resource management factors on turnover intension and organizational loyalty. It has been observed that the level of LMX is critical on the turnover intension, while the levels of LMX and TMX are positively related to the organizational loyalty. Especially significant mediation effect affects on the organizational loyalty for TMX via LMX in the serial structure. The human resource management factors become effective under the circumstances where leader and team members exchange activities are activated. These findings can be used in reducing turnover intention and increasing organizational loyalty of early experienced employees by enhancing the leadership training of middle level managers of the small and medium enterprises organizations. Besides, a set of active communication channels should be provided for the young employees so that they can share their work experiences and difficulties within the organization. The key results of this study may help the practitioners set up a management plan to maintain a low turnover rate for their organizations.

Objective: The aim of this study is to evaluate the effectiveness and efficiency of causal links between various error causes in human error analysis. Background: As finding root causes of human error in safety-critical systems is often a cognitively demanding and time-consuming task, it is particularly necessary to develop a method for improving both the quality and efficiency of the task. Although a few methods such as CREAM have suggested causal linking between error causes as a means to enhance the quality and efficiency of human error analysis, no published research to date has evaluated the performance of the causal links. Method: The performance of the CREAM links between error causes were evaluated with 80 railway accident investigation reports from the UK. From each report, errorneous actions of operators were derived, and for each error, candidate causes were found by following the predefined links. Two measures, coverage and selectivity, were used to evaluate the effectiveness and efficiency of the links, respectively. Results: On average, 96% of error causes actually included in the accident reports were found by following the causal links, and among the total of 121 possible error causes, the number of error causes to be examined further was reduced to one-tenth on average. As an additional result of this work, frequent error causes and frequently used links are provided. Conclusion: This result implies that the predefined causal links between error causes can significantly reduce the time and effort required to find the multiple levels of error causes and their causal relations without losing the quality of the results. Application: The CREAM links can be applied to human error analysis in any industry with minor modifications.

Purpose: This study was to examine the ego-identity of nursing students and their adjustment to home and university in an effort to identify the correlation of their ego-identity to their adjustability and lay the foundation for providing better personality education to them. Method: The subjects in this study were 400 nursing students at H and S universities in south Chungcheong province. The instruments used in this study were Park A-cheong(2003)'s Korean-version Ego-Identity Inventory and Jeong Jonggweon(1998)'s Home and School Adjustment Inventory. For data analysis, SPSS/PC+ Package was used, and statistical data on frequency and percentage were obtained. Besides, t-test, one-way ANOVA and Pearson correlation coefficient were employed. Result: The findings of the study were as follows: The nursing students investigated got a 3.46 and 3.53 in ego-identity and family life adjustment respectively out of possible five points, which were both above the average. Their score in school adjustment was 2.89, which wasn't high. As for connections between general characteristics and ego-identity, their academic school year, their type of residence, presence or absence of parents and their birth order made no statistically significant differences to their ego-identity. But as to motivation of choosing nursing, the students who chose their major at their own option were the best in that regard. Their adjustment to family life made no significant differences, and regarding school adjustment, ego-identity was better among those who lived in a lodging house or dormitory(F=4.01, p<.05) and who chose their major at their own option(F=4.88, p<.01). In addition, those with better ego-identity were better adjusted to home and school. Conclusion: As the above-mentioned findings suggested that nursing educators should teach students by mapping out specific plans to enhance the ego-identity of students and facilitate their school adjustment, and full-fledged nurses should be produced by teaching students to build the right work ethics and become qualified as a professional.

It is a recent trend to emphasize community services for the rehabilitation of the mentally ill. However, it is also necessary to provide social work services for those living in the institutions, who is the most underprivileged in our society. To deal with interpersonal skill deficits which is one of the main characteristics of the mentally ill, social skills programs are being utilized, usually in the communities, but not in the institutions. Therefore, the objective of this study is to develop and evaluate institution-relevant program for the improvement of assertiveness, which is the basic ability among the interpersonal skills, and self-esteem, which is the emotional basis of assertiveness. Because there has been little literature on such a program, a preliminary program had been implemented in order to include the peculiarities of the life in the institutions on the main program. The evaluation of the program effect was done by pretest-post test control group design, and its results are as follows. Firstly, in regard to program effectiveness, the pre and post test showed that self-esteem improved in a statistically meaningful way, but that assertiveness did not so. However, the staff verified the improvement of the group members' assertiveness to some degree in their actual lives. Secondly, in regard to the group process, the group interaction improved in a statistically meaningful way between 2nd and 5th session, and the improvement maintained till the program termination. Also the group members evaluated the program as helpful in their everyday lives. Therefore it can be said that the result of this program is encouraging. In light of this, several suggestions were made: utilizing more dynamic techniques in the program; developing the advanced level of the program; making an effort to change environmental structures as well as individuals; applying this kind of program to another living facilities such as those for the homeless or handicapped.

Technological and organisational changes in transport system have introduced new dimension into port system development and inter-port competition. The quality of service now required by the customer is costly and not easily provided by small shipping companies and small ports. It has been suggested that in the future container shipping may be concentrated by space-sharing arrangements or actual mergers into the hands of a few mega-operators with the investment potential to provide total logistics networks. In order to compete effectively, high load factors will be essential and port concentration inevitable. A fa-voured few ports will become the load centres and other ports will assume a secondary feeder role. In this study, three questions are raised and attempts are made to answer them : (a) what is the new role of ports today ; (b) why should ports be engaged in this new role ; and (c) how can ports play this new role. In short, a modern port should be a service centre and a logistic platform for international trade and transport-a third generation port. Ports, in particular, have to make every effort to be competitive in the cost and quality of services and to make the port a transport and distribution service centre. For most ports, this is not an option but a must ; an essential requirement for survival in this win or lose situation. The best way to win is to maintain a close contact with port users, listen to them, discuss with them, help them and satisfy them. That is port marketing. Starting from the findings of port marketing, it is es-sential to work out appropriate development plans and marketing targets and to improve port competitive-ness. As an alternative method, a port competitiveness model is suggested, which may help port managers to make appropriate improvements.

본 논문에서는 태스크에 따른 저전력 알고리즘을 제안하였다. 태스크는 시스템의 작업 수행에 필요한 프로세서의 내부와 외부의 자원을 의미한다. 태스크에 따라 저전력 회로를 구현하기 위해서는 각각의 태스크에 대한 생존시간과 호출횟수를 분석한다. 회로 전체의 소모 전력을 감소하기위해서는 소모 전력이 가장 높은 태스크의 소모 전력을 우선 줄여 저전력 회로를 구현할 수 있다. 따라서 소모 전력이 최대인 태스크를 우선 선별하여야 한다. 소모 전력이 최대인 태스크는 태스크의 생존시간과 호출횟수를 고려하여 순위를 선정한다. 태스크의 생존시간이 길면서 호출횟수가 많은 태스크의 경우 가장 큰 소모 전력을 발생시키는 태스크이므로 소모 전력을 감소시킬 최우선 순위가 된다. 소모 전력이 최대인 태스크로부터 생존 시간과 호출횟수를 이용하여 저전력 회로로 구현하기 위한 주파수를 결정하여 회로 전체의 소모 전력을 감소시킨다. 또한, 생존 시작 시간에서 생존 마지막 시간까지 계속해서 최소의 소모 전력으로 태스크를 유지시켜 전체 소모 전력을 감소시킨다. 실험 결과 [7] 알고리즘에 비해 5.43%의 전력 소모가 감소된 결과를 나타내었다.

This study was carried out to evaluate high-school students' nutrient intakes according to the status of body mass index, and to analyze the Physical health status. The volunteers were 560 high school students in 8 provinces, but 511 students were analyzed. It was used questionnaire method as an instrument tool. The questions were composed with socio-demographic characteristics, physical health condition by CMI. and the evaluation of food consumption by 24 hours recall method. Anthrophometric measurement of height and weight was used the data of health chart of each school-class. The family situation of the subjects was mostly nuclear family(73%), agricultural work(53%), and normal living situation(75%). The students of the BMI range of 18-23 were 71%. but those of the overweight(over 23) were 15%. The individual characteristics were different in BMI. Female and third grade students were more of BMI scores. The overall nutrient intakes of students were low compared with Korean RDA of adolescent. especially iron. calcium. vitamin A, and riboflavin. The mean adequacy ratio(MAR) of nutrient intakes was 0.45$\pm$0.23 only. The energy nutrients, ash, and vitamin A intakes were significantly different according to the different BMI groups. But the other mineral and vitamin intakes were not different according to BMI. By the correlation of individual characters with BMI, height was negatively and weight and school grade were positively correlated, but sleeping time and study accomplishment were not correlated. By the correlation of nutrient intakes with BMI, there were negative correlation with the intakes of energy, carbohydrates, potassium, and thiamin. According to this results, We concluded that Korean high-school students living in rural were lower intake of nutrients(iron, vitamin A, and riboflavin) and unbalanced nutrient intakes(MAR of 0.45$\pm$0.23). The state of lower intakes of energy nutrients and vitamin A intakes in higher BMI group mean the students spend their effort to reduce BMI for avoiding obesity. But they need to balanced diet. and good nutrient intakes. These situations would be necessary for students to ameliorate quality of living in rural.
