Leader-Member Exchange (LMX) model of leadership has suggested that members within the same work team are differentiated in terms of their level of the quality of leader member relationships. However, the differentiation in leader member relationships has not been examined for its possible team-level effects. In this study, the possible impact of this role differentiation on team members' affective reactions was explored. As hypothesized, teams whose members experienced higher level of LMX tended to have higher overall job satisfaction, organizational commitment, and team efficacy. Contrary to expectation, however, the team-level mean on LMX was not related with team-level variability on LMX. Based on these findings, several theoretical and practical Implications are discussed.

적외선 영상은 야간에 표적의 탐지가 가능하여 보완과 감시분야에 활용도가 높다. 그러나 가시광선 영상에 비하여 해상도가 낮고 잡음의 영향이 크다는 단점이 있다. 본 논문에서는 적외선 영상의 표적을 분할하는 방법을 연구한다. 표적을 포함하는 다수의 관심영역(Region of Interest)을 다단계 분할 방법을 이용하여 추출하고 관심영역을 입력영상으로 다단계 분할방법을 다시 적용하여 표적을 분할한다. 다단계 분할 방법의 각 단계는 가우시안 혼합모델의 파라미터를 초기화 하고 추정하는 k-means 클러스터링(Clustering)과 EM(Expectation-Maximization) 알고리즘과 추정된 사후확률을 이용하여 각 화소의 클러스터를 결정하는 단계로 구성된다. 본 논문에서 추출된 관심영역을 선택하고 통합하는 방법을 제안한다. 관심영역의 통합은 근접한 모든 관심영역의 윈도우를 포함하도록 이루어진다. 실험에서는 야간의 보행자로부터 획득한 적외선 영상에 제안된 방법을 적용하고 다른 분할 방법과 비교하여 제안한 방법이 우수함을 보인다.

This study is a descriptive analytic research measuring nursing service quality, using SERVQUAL model, to make fundamental data and strategies for nursing service improvement. Data were collected by self-reported questionnaire from 202 patients and 142 nurses, from June 7 to 14, 1999. The reliability of instrument were adequate(Cronbach ${\alpha}=.94$). SAS program was utilized for statistical analysis of collected data. The results were as follows; 1. There was a gab between patient's expectation and perception on nursing service(Gap B). Gap D was indicated an affecting factor to decide nursing service quality. Gap C was indicated an indirect affecting factor of nursing service quality. Because it was not statistically significant in total item analysis, but in individual item analysis, 7 items were appeared statistically significant. Gap A was not a gap occurrence factor of nursing service quality. 2. Focuses of nursing service quality improvement strategies were; (1) to direct qualitative improvement of nursing service in order to correspondence patient's nursing service expectation. (2) to make nurse's service activity modified because nurse's practice were not reached patient's expectation level. (3) to need internal, external factor analysis affecting nurse's service activity. 3. Nursing service quality was decided by rather environmental inappropriateness provided nursing service than itself. Therefore, to make nursing service quality improvement, it is required to improve nursing service environment. For this, followings are required; (1) to strengthen nurse's education on lower part of nursing service satisfaction and QI activities. (2) to balance demand and supply of nursing personnel. 3) to fix computerized system for reducing other duties weight except nursing care through analysis of nursing activity. (4) to construct rational cooperating system among related departments. 4. The important parts for nursing service quality improvement were indicated as follows: (1) Gap B: 'prompt reaction', 'examination symptom before patient's complaint', 'hearted nursing service reducing patient's dissatisfaction', 'explanation goals of nursing activities', 'having special Knowledge enough', 'maintenance position comfortably', 'management of patient's physical hygiene'. (2) Gap C: 'maintenance physical safety', 'explanation about hospital rules and facilities'. (3) Gap D: 'tender, safe injection and wound care'. Because above items are mostly improved through nurse's attitude change and quality improvement, it is required to establish nursing standardization and to strengthen nurse's clinical education. As the based on above results, followings are suggested; 1. SERVQUAL model is very useful to make strategies for nursing service quality improvement because it indicates multiple factors affecting hap occurrence. 2. At individual items analysis of Gap C, statistically significant 7 items appeared higher nurse's perception level than patient's perception level on nursing service were trouble perception level on nursing service quality improvement. So. it need further research to analysis about these difference occurring factors. 3. At analysis of Gap D, it is indicated that in nursing service performance process, multiple factors lowing nursing service quality were intruded. So it needs further research to analysis what these factors are and how each factors affect on nursing performance process. 4. nursing service quality measurement is changeable according to sample select time or sampled subject's characteristics. So to develope strategy for nursing service quality improvement is based on the results of periodical analysis.

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.

The purpose of this study was to examine how immigrant Korean American parents' aspirations for children's educational attainment are related to their childrearing behavior, their beliefs about the nature of children's intelligence, their level of acculturation, and their beliefs about achievement. One hundred and twenty five immigrant Korean mothers in the United States participated in the study. The present study found that parental expectation for a daughter's educational attainment was significantly related to the mother's educational level. The results of regression analysis also indicated that for daughters, the significant predictors for parents' aspirations for children's educational attainment were the mothers' educational level and parental beliefs about achievement; for sons, significant predictors were the mothers' educational level and parental nurturance.

This paper presents an integral model for product safety and product liability resulting from a defective product. The essence of the paper is the process of supply of manufacturing products which satisfy the product liability and the product safety in terms of consumers expectation levels. The main criteria of the product safety is the hazard level which involves in the severity and frequency. The proposed model shows the process to supply the manufactured products under the conditions that they are suitable in comparison of hazard level and safety level established by each company. If the product do not meet the safety level, this paper proposes that four different types of PL and PS countermeasures for the risk types are forward, respectively.

Schools are expected to ultimately moderate the difference of inequality issues among social groups and reduce the achievement gaps. This study investigates this expectation, in particular, how students' mathematics achievements are influenced by their parents' education at the individual level and by collective responsibility for teaching at the school level as well as the interaction of the two. Using a two-level hierarchical linear model, this study indicates that a school collective responsibility has a larger positive effect on students' mathematics achievement when their parents' education level is high. This means that school's collective responsibility accelerates inequity in students' mathematics achievement. Knowing that collective responsibility has less of an effect on students whose parents' education is not high, researchers, schools, and school districts should continue to search for school effects that have more of a positive impact on the relationship between mathematics achievement for students whose parents' education is not high in order to have more equitable results for all students.

Critical to project success is effective stakeholder management. This paper presents a challenge for the project manager who uses traditional approaches to manage mid-level stakeholders in an organization. Dual roles of a mid-level stakeholder (as a stakeholder of a project and as an agent of the corporate) may cause problems that would result in difficulties for project managers in identifying the stakeholder's attributes and overcoming hierarchical authority expectation. However, the dual roles of the stakeholder result in its weakness in the project-stakeholder relationship. Can a project leverage its strategic role for effective upward influence by linking project objectives to corporate strategic objectives? To address this research question, case study method was used to gain a deeper understanding of mid-level stakeholder's salience. This research proposes an upward influence strategy to embed a project-stakeholder relationship in a hierarchical stakeholder network.
