Scenario-based learning (SBL) has been used in a variety of training situations across different disciplines. Despite its seemly widespread use in construction management discipline, very few attempts have been made to explore its effectiveness and the respective students' learning experience. Using a survey research design, this study aims to investigate students' perceptions on SBL approach in construction management courses. The specific objectives are: (i) to identify the characteristics of a favourable SBL environment, and (ii) to explore the students' learning experience and effectiveness of the SBL approach. The results show that the four characteristics of a favourable SBL environment are: effective team formulation, constant engagement with lecturer, working in a group, and incorporation of motivational incentive for participation. The students really appreciated the opportunities to apply concepts learnt in the lectures in their SBL group work. Also, they perceived that the SBL approach is effective in developing their reflective and critical thinking skills, analytic and problem-solving skills and their ability to work as a team. These findings should facilitate more critical approaches to similar form of teaching methods.

This study was designed to examine the extent of job-related stress and job satisfaction and factors affecting job satisfaction of educare center teachers. Special attention was given to the differences due to the various organizational types of educare centers. Two hundred and twenty two public and private educare center teachers of C city were drawn as samples of this study. Self-administered questionnaire method containing items (m job-related stress, Job satisfaction and socio-demographic background was employed and the data were analyzed with SPSSWlN using descriptive statistics, factor analysis and regression analysis. Findings suggested that the major job-related stresses were related to work experiences, working hours, and the number of on-the-job training opportunities. Work place characteristics such as the total number of children in the class, working hours and wage also affected the level of Job satisfaction. Additionally significant statistical differences were found on the job-related stress and the job satisfaction between teachers in public and private educare centers. In the question of the effect of job-related stress on the job satisfaction, job-related stress explained 12% of work-satisfaction, 33% of satisfaction related to the current working place. Accordingly it was possible to draw a conclusion that educare center teachers' job-related stresses. were not ascribed by personal characteristics but by work-related factors such a, poor administrative support low wage and the overwhelming task related stressors The main stressor of job satisfaction was poor administrative support. Differences on job-related stress and job satisfaction_between among teachers of public and private unit were distinctive throughout the study. These results, implicate that workshops are recommended to help diminish the job-related stress among educare center teachers. It is imperative that enhanced work benefits and improved working environment will in turn enhance the quality of services in educare centers.

In this study, the distribution characteristics of diffusers with various shapes that are installed in an open-type thermal storage system are numerically investigated. Four diffusers are designed to distribute a working fluid evenly through the holes on bifurcated pipes. Three-dimensional steady simulations of incompressible laminar flow are conducted using commercial software (ANSYS-FLUENT). The simulation results show that both the bidirectional header-type diffuser and the H-type diffuser distribute the working fluid evenly whereas both the unidirectional and the bidirectional diffusers distribute the working fluid unevenly. The results also show that the H-type diffuser requires a higher head of pump than the bidirectional header-type diffuser. Therefore, the bidirectional header-type diffuser is recommended for use because it enables even distribution of the working fluid and requires a low head of pump.

This study attempted to look into the effects of the job environment and job esteem on job satisfaction in the field of skin beauticians. To achieve this, a survey of their characteristics, job environment, job esteem and job satisfaction was carried out on 470 women in their 20s~50s working at skin care shops in the Seoul and Gyeonggi areas. First, it was found that the effects of the working environment on their vocational satisfaction, sense of belonging, level of contribution, wages and welfare, which are sub-factors of job satisfaction, are relatively high. This result shows that it is important to ensure proper resting facilities and resting areas. Second, it was shown that the higher the social evaluation, self-(implicit) assessment, future value, and self-fulfillment orientation, the higher the sub-factors of job satisfaction. This means that it is important to treat skin beauticians as professionals in order to improve their social recognition. The sub-factors of job environment-working conditions, organizational environment and job stability, and sub-factors of job environment-social evaluation, self(intrinsic) evaluation, future value and self-achievement orientation, had a major effect on the sub-factors of job satisfaction, respectively. Together with the general improvement in the sub-factors of job environment, the future value, as well as social evaluation, self(intrinsic) evaluation and self-achievement orientation, which together constituted the current value of job esteem, were the major factors affecting job satisfaction. Consequently, this study hopes to contribute to the development of the skin beauty industry by providing basic data on personnel management for skin care managers to improve skin beauticians' job satisfaction.

Nowadays, most big hospitals have a computer system to manage their administration. For maxi mum effectiveness in managing the computer system, an analysis of the variables affecting its implementation is necessary from the beginning. This study was done to analyze the variables influencing the operation of a hospital information system (HIS). The theoretical base for this study considered the combined effects of user expectations of computerization, and computer-anxiety. The relationship between variables in the theoretical base were analyzed and the individual characteristics influencing each variable were also analyzed. This study was done in two steps. First, 344 nurses were given an initial questionnaire developed to evaluate the reliability of the items. Based on the results, a second revised questionnaire was administered to 88 nurses who had been working in the areas where HIS was applied. The results of the first and second steps of the study are as follows 1. The initial study was done with nurses who were trained on the computer system briefly before HIS was implemented. The individual characteristics influencing computer anxiety and expectation regarding computer system usage in that initial study included, length of career, type of degree or certification, previous experiences with a computer, training on a computer, desire for computer training, and level of acceptance of a computerized work environment. But in the second study with nurses working in areas of the hospital where HIS was introduced, the work site was the only influencing characteristics. There-fore, in applying a computer system, overcoming work-environment barriers will be more import-ant than any individual characteristics. 2. The computer anxiety of the nurses in both groups, before and after the computer system ap-plication, was below the average level but the expectation of the effects of computerization was above average. The nurses using the computer program showed an above average level of satis-faction with the computer system itself, and with its effect on their efficiency. Therefore, the ability of nurses operating HIS will be positively. predictive. 3. For the variables included in the theoretical framework of the study, all of the correlational coefficients were statistically significant in the analysis of variation correlation. Therefore, the theoretical base of the study, "expectation in con junction with computer anxiety" can be considered an model which can be evaluated. Accord-ing to our analysis, the higher the level of nurses' motivation to use the computer system and the lower the anxiety about computer usage, the higher the possibility of computer system acceptance by nurses. The results of this study showed that in applying a computer system in the hospital, the main characteristic influencing acceptance was where the individual worked rather than personal characteristics such as length of career, type of degree or certification, and previous experiences with a computer. Therefore, it is suggested that the first step in uncovering and eliminating hindrance factors in ap-plication of a computer system should be an analysis of working conditions in relation to the functional content of the computer system. The suitability of the theoretical model based on the hypothesis ap-plied in this study should be further tested.
