1) Background: The hospitals of modem society, like any other business entities, have to constantly strive to secure their survival from aggressive changes and competition outside. In this unstable environment, effective leadership is one of the most effective strategies for securing organization's growth as well as stability. This study investigated types of leadership (transformational or transactional) that is dominant in medical record departments and compared it's effects on organizational commitment and job satisfaction of their organizational members by types. 2) Method: A questionnaire was developed and mailed to all medical record administrators working at general hospitals throughout the country except department directors (N=450). Of these, 150 useable questionnaires were returned and analyzed by t-test, multiple regression analysis using SPSS. 3) Results: The organizational commitment and job satisfaction were a little bit higher than moderate level, and that of leadership perceived by medical record administrators was also in moderate level throughout types. Significant characteristics (positively) related to organizational commitment and job satisfaction by univariate analysis were marital status (married), position (middle management) and both type of leadership. However transformational leadership was the only significant factor in leadership styles after considering all the factors related to organizational commitment and job satisfaction together by multivariate analysis. 4) Conclusion: The average organizational commitment and job satisfaction of medical record administrators was just in moderate level. Efforts should be made to increase them by improving leadership capacity of medical record directors, primarily by using transformational leadership approach.

컨테이너의 양 ${\cdot}$ 하역 작업 시 크레인을 정 위치에 고정시키고, 돌풍으로 인해 크레인이 레일방향으로 미끄러지는 것을 방지하는 장치가 레일클램프이다. 쐐기형 레일클램프는 풍속이 증가하면 쐐기작용에 의해 압착력이 증가하므로 구조적으로 안정성과 내구성이 있게 설계해야한다. 따라서 본 연구에서는 순차적 표본방법을 기반으로 하는 크리깅 모델을 이용하여 조 형상최적설계를 수행하였다. 크리깅은 표본점의 반응치를 기초로 내삽법에 의해 임의의 점에서의 반응치를 예측하는 근사기법의 하나이다. 이것은 최적설계 분야에서 자주 사용되는 근사기법인 반응표면법에 비해 반응치의 보다 정확한 예측이 가능하며 특히 비선형성이 강한 함수의 예측에 적합하다고 알려져 있다. 순차적 크리깅 모델에 의하여 구해진 최적해를 상용프로그램을 이용하여 구한 최적해와 비교하고 제안된 방법의 유용성을 검토하였다.

PURPOSES : It is difficult to estimate tunnel stability because of lack of timely information during tunnel excavation. Tunnel deformability refers to the capacity of rock to strain under applied loads or unloads during tunnel excavation. This study was conducted to analyze a methods of pre-evaluation of stability during tunnel construction using the critical strain concept, which is applied to the results of tunnel settlement data and unconfined compression strength of intact rock or rock mass at the tunnel construction site. METHODS : Based on the critical strain concept, the pre-evaluation of stability of a tunnel was performed in the Daegu region, at a tunnel through andesite and granite rock. The critical strain concept is a method of predicting tunnel behavior from tunnel crown settlement data using the critical strain chart that is obtained from the relationship between strain and the unconfined compression strength of intact rock in a laboratory. RESULTS : In a pre-evaluation of stability of a tunnel, only actually measured crown settlement data is plotted on the lower position of the critical strain chart, to be compared with the total displacement of crown settlement, including precedent settlement and displacement data from before the settlement measurement. However, both cases show almost the same tunnel behavior. In an evaluation using rock mass instead of intact rock, the data for the rock mass strength is plotted on the lower portion of the critical strain chart, as a way to compare to the data for intact rock strength. CONCLUSIONS : From the results of the pre-evaluation of stability of the tunnel using the critical strain chart, we reaffirmed that it is possible to promptly evaluate the stability of a tunnel under construction. Moreover, this research shows that a safety evaluation using the actual instrumented crown settlement data with the unconfined compression strength of intact rock, rather than with the unconfined compression strength of a rock mass in the tunnel working face, is more conservative.

Background: Fatigue has a strong impact on workers' performance and safety, but expedient methods for assessing fatigue on the job are not yet available. Studies discuss posturography as an indicator of fatigue, but further evidence for its use in the workplace is needed. The purpose of the study is to examine whether posturography is a suitable indicator of fatigue in clerical workers. Methods: Thirty-six employees (${\emptyset}$ 34.8 years, standard deviation = 12.5) participated in postural tasks (eyes open, eyes closed, arm swinging, and dual task) in the morning and afternoon. Position of their center of pressure (COP) was registered using a Nintendo Wii Balance Board and commercial software. From registered COP time series, we calculated the following parameters: path length (mm), velocity (mm/s), anterior-posterior variance (mm), mediolateral variance (mm), and confidence area ($mm^2$). These parameters were reduced to two orthogonal factors in a factor analysis with varimax rotation. Results: Statistical analysis of the first factor (path length and velocity) showed a significant effect of time of day: COP moved along a shorter path at a lower velocity in the afternoon compared with that in the morning. There also was a significant effect of task, but no significant interaction. Conclusion: Data suggest that postural stability of clerical workers was comparable in the morning and afternoon, but COP movement was greater in the morning. Within the framework of dynamic systems theory, this could indicate that the postural system explored the state space in more detail, and thus was more ready to respond to unexpected perturbations in the morning.

Purpose: This study was a cross-sectional study done to determine the relevance and impact factors of nursing practice environment and self-esteem on critical thinking disposition in clinical nurses. Methods: A survey was conducted from March to May 2015 with self-report questionnaire. Participants were 281 registered nurses working in one tertiary hospital. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation, and multiple regression with SPSS/WIN 21.0. Results: Factors affecting the nurses' critical thinking disposition included age (F=7.23, p<.001), educational background (F=7.82, p<.001), position (F=14.95, p<.001), clinical career (F=7.66, p<.001). Further, critical thinking disposition had a positive correlation with nursing practice environment (r=.60, p<.001) and self-esteem (r=.41, p<.001). Self-esteem and nursing practice environment accounted for 43% of the variance in critical thinking disposition. Conclusion: The study findings show that critical thinking disposition is influenced by nursing foundations for quality of care and the collegial nurse-physician relations of nursing practice environment. Therefore, it's necessary to provide continuing education for clinical nurses to reconstruct the organizational culture of nurses and physician partnerships. In addition, increasing self-esteem through various motivational programs should increase critical thinking disposition.

Purpose: The study was undertaken to examine the degree of nurse's suffering experience and to identify the influencing factors on nurses' suffering experience in Korea. Method: Data were collected using a questionnaire for 271 nurses working at 5 general hospitals in Daegu and Kyung-book province from Sep. 1, to Sep. 30, 2003. The questionnaire consists of 54 items, general characteristics(10) and nurse's suffering experience(44). All surveys were sorted and studied by frequency analysis, mean score, standard deviation, range, independent t-test, one way ANOVA, Pearson's correlation coefficient and Multiple regression. Result: The findings of this survey indicate 1) The degree of suffering experienced by nurses caring for terminal cancer patients was 2.96; 2) Demographic variables affecting the degree of nurses' suffering experience were age(F=5.62, p=.000), marital status(F=20.53, p=.000), religion(F=5.44, p=.020), career of clinical experience(F=6.96, p=.000), and feelings of end-life care(F=3.11, p=.016); 3) There were slight correlation between the subitem of nurse's suffering experience and general characteristics of subjects. For 'expanding self consciousness', age, career duration, and position; for 'forming empathy with family', age and career duration ; for 'spiritual sublimation', age, and career duration were affected variables. 4) As a result of the multiple regression analysis for predictable variables affecting nurses' suffering, it was found that 'career of clinical experience' was most significant(F=23.100, p=.000). The explanatory power of this regression formula was 17.6%. Conclusion: This study can provide the basic data useful towards improvement of nursing services for terminal cancer patients and the health of the nurse.

This study attempts to analyze the factors affecting the intention of transferring to another hospitals among radiology technologists. 344 cases were reviewed in 5 university hospitals and 1 general hospital. Self-administered questionaire were given to study the socioeconomic characteristics, working conditions, job satisfaction level, and the reasons for transfer among the technologists. The major findings were as follows : 1. Job position and hospital characteristics had a statistically significant relationship with the intention of transferring to another hospital. 2. Those who were not satisfied with their salaries and promotional opportunity showed a higher tendency towards to transfer. 3. Those who were less satisfied with the opportunity for developing the personal ability and had the negative attitude on their job showed a higher tendency to transfer. 4. Those who did not sustain good relationship with their superiors and co-workers scored high on the tendency to transfer. 5. In the result of mutiple regression, recognition of radiation hazard, job satisfaction, satisfaction with salary levels, job attitude were significantly related to transfer. The above indicate that besides economic incentives, job satisfaction and organizational culture to promote their ability and form a good relationship with organization members were very important to decrease the intention of transfer. Since these results represent only 6 hospitals from a limited area, more hospitals nationwide, especially small and medium-sized institutions where there is a high turnover rate of employment, need to be examined in order to investigate the various factors that affect the intention of transferring.
