Objectives : This study was conducted to review the diffusion process and factors affecting the adoption of the Health Center Information System (HIS). Methods : Data were collected from POSDATA (private company), MOHW, other Ministries and local governments. To specify the date of adoption, supplementary information was collected from 40 health centers. The following three kinds of factors were analyzed. Internal factors included type, size, and innovativeness of health centers. Community factors were composed of population sire, economic status, and level of education. Organizational environmental factors consisted of information score of the municipalities, financial support of the from central government, and the neighborhoodness of innovator health centers. Results : All health centers in the metropolitan cities of Seoul, Gwangju and Jeju adopted the HIS. The laggards were those in the metropolitan cities of Busan (18.8%), Incheon (20.0%) and Daejun (20.0%), and cities with population more than 300,000 (54.8%) and counties with health center hospitals (47.1%). Financially supported rural health centers adopted the HIS more rapidly than those not supported. The factors identified as being statistically significant (p<0.05), from a univariate analysis by Kaplan-Meier method, were: (1) internal factors of the type, size and innovativeness of health centers; (2) community factors of population size and economic status; (3) organizational environmental factors of the central government financial support and the neighborhoodness of innovator health centers. A multivariate analysis, using a Cox proportional hazard method, proved the innovativeness of health centers, central government financial support and the neighborhoodness of innovator health centers, were statistically significant (p<0.05). Conclusions : The innovativeness of health centers, financial support from central government and the neighborhoodness of innovator health centers, rather than community factors related to regional socioeconomic status, affected ffe adoption of the HIS in health centers. Further in-depth studies, modifying the MOHW's strategy to propagate the HIS to the laggard health confers, are recommended.

Background: Conservation of blood during cardiac surgery is important because of the shortage of donor blood, risks associated with transfusion, and the costs of allogeneic blood products. This retrospective study explored the feasibility of off-pump coronary artery bypass (OPCAB) without transfusion. Methods: One hundred and two consecutive patients underwent OPCAB from January 2007 to June 2012 at Hallym University Sacred Heart Hospital. Excluding 10 chronic renal failures patients, 102 patients were enrolled. Their characteristics, clinical data, and laboratory data were analyzed. We investigated the success rate of OPCAB without transfusion according to preoperative hemoglobin (Hb), and the cutoff point of the Hb level and the risk factors for transfusion. We implemented multidisciplinary blood-saving protocols. Results: The overall operative mortality and the success rate of OPCAB without transfusion were 2.9% (3/102) and 73.5% (75/102). The success rates in patients with Hb<11, 11 70 years, diagnosis of acute myocardial infarction, preoperative Hb and creatinine levels, and operation time. The events precipitating the need for transfusion were low Hb level in 9 patients and hypotension or excessive bleeding in 18 patients. Conclusion: The preoperative Hb level of >11 facilitates OPCAB without transfusion. These results suggest that transfusion-free OPCAB can be performed by modifying the risk factors and correctable causes of transfusion and improving various blood salvage methods.

Space evolves from the concept of deterministic static location to a dynamic, connected area through the interference of the user. While this does incorporate physical changes of the space, it also reflects the changes of the program or characteristics of the space through the actions and changes of the user. Therefore, in this study we plan to review the characteristic of time appearing within space, thereby discussing the impact of changing of condition in time-space to the decision making of the user. Further, we plan to analyze the specific causes, and subsequently introduce a new perspective over space. In order to achieve this, we need to first understand the reason why the attribute of time needs to be discussed in space, and perform a fundamental analysis of factors for the changes of the users' actions following changes in space-time condition. This means that space is not limited to merely satisfying its innate objective as an area, but may have a basis for modifying its role to help the decision making of the users caused by changes in space-time conditions. Accordingly, we analyze the factors for change of environment that can appear in space following the flow of time caused by correlation in space-time, as well as psychological factors and variables for decision making by the users. Based on this, we analyze cases to study the influence of condition changes in time-space on the action decision judgment of the users. Through this, we propose that the actions of the users can be determined following changes in time-space conditions, and discuss the need for changes in our perspective of space.

This descriptive correlational study was conducted to identify the variables related to health promoting lifestyle of girls in High school students. 156 high school students and 88 vocational high school students who lives in Taegu city were selected by a convenience sampling method. The data were collected by self-reported questionnaires from August 24 to September 4. 1998. Pender and others' Health Promoting Lifestyle Profile. Shere et al's. Self-Efficacy scale. Wallston et al.' s Internal Health Locus of Control scale. Wares' Health self rating scale and Cohen & Hoberman's Social support scale were used. The data were analyzed by using descriptive statistics, Pearson correlation coefficient. t-test. MANOVA. ANOVA. Tukey verification and Stepwise multiple regression with SAS progrom. The results of this study were as follows : 1. The average score of health promoting lifestyle performance was 2.34(SD=.36)points by the 4 point scale. 2. The combination of self-efficacy. internal health locus of control. mather's educational level and type of school explained $41.31\%$ of the variance of health promoting lifestyle. 3. Health promoting lifestyle showed significant positive correlations with self efficacy(r=.5173. p=.001), perceived health status(r=.254, p=.001) and internal health locus of control(r=.321. p=.001). On the basis of the above findings, self-efficacy in cognitive factors. and social support in modifying factors were identified as the variables which explained the most part of the Pender's health-promotion model. Nursing strategies enhancing self-efficacy which has the most significant effect on health promoting lifestyle should be developed. Further research is required to find out the factors influencing health pormoting lifestyle of high school students.

Follicular atresia is a universal and characteristic phenomenon of both non-mammalian and mammalian vertebrates. Generally it is estimated that greater than 99% of follicles become atretic in higher domestic animals and human. The number of selected follicles developing to the preovulatory stage are thus fewer. Follicles can become atretic at any stage of development. The previous studies emphasized on descriptive and retrospect aspects of a limited population of the fully grown preovulatory follicle. The main efforts in ovarian physilogical researches are focused on follicular development culminating in ovulation but recent advances have resulted in a better understanding of atresia. Nowadays, recent studies are concentrated on the induction of atresia in a selected population of follicles and of the associated cellular, endocrine, biochemical and molecular changes. The factors initiating atresia and follicle selections are worthy of investigations. Another intriguing question is whether one can predict when a follicle will become atretic, i.e., what biochemical markers indicate that a follicle is destined for atresia. It is generally agreed that atretic process may vary even in antral follicles at different stages of their differentiations and among species. The dicisive factors are follicular responsiveness and the hormonal milieu. Some generalizations can be made on the basis of experimental induction of atresia. Alteration of the pattern of follicular steroid production is associated with the initiation stage of atretic process. Atresia appears to be a process unfolding gradually and affecting progressively in increasing number of functions and components of the follicle. The oocyte may be the latest to be afflicted in the atretic process. The high steroidogenic activity of atretic follicles lends support to the notion that atresia is not necessarily a degenerative process and that atretic follicles may play an essential role in ovarian physiology. The simultaneous occurence of growth and atretic processes may render the search for regulatory mechanisms involved in atresia difficult extremely. The questions such as how follicles are selected to undergo ovulation rather than atresia or what the mechanism of atresia is remain unanswered. However, the factors regulating or modifying ovarian hormonal milieu for the initiation of follicular growth and maturation or of atresia are being elucidated.

The Health Promotion Model by Pender(l987) was used as the conceptual framework for analyzing the health promotion behaviors. The purposes of this study were to describe health promoting life style behaviors in 245 women between the ages of 35 and 59 living in Seoul and other cities and to find their predictive factors. Data were collected from 1st to 23th. June. 1998. The tool used for this study was structured questionnaire with consisted of 8 items on general characteristics. 5 items on health related characteristics. 43 items on health promoting life style. 28 items on menopausal symptoms. 5 items on family support. and 28 items on self-efficacy. The collected data were analyzed using the SAS. yielding descriptive statistics. ANOVA. Pearson's Correlation. stepwise multiple regression. The findings of this study are as follows. 1) The mean score of health promotion behavior(3.25) is not high. The mean scores of this self actualization (3.73). interpersonal support (3.68). and nutrition (3.57). regulation of stress (3.22) in domains are higher than health responsibility (2.90). exercise (2.63). 2) The results of the comparison between the health promotion behaviors and general variables showed a statistically significant difference in education (P=.0061), domestic economy status(P=.0001). perception of health status(P=.0001) but. age. state of menstruation. perception of weight is not significant difference. 3) The correlation between health promoting life style and self-efficacy(P=.0001). family support(P=.0001) is significant. But. there is no correlation between health promoting life style and age. number of family. perception of weight. 4) In the cognitive-perceptual factors. self-efficacy (P=.0001) is very significant predictor (accounted for $39.7\%$) and in the modifying factors. family support(P=.0001) is very significant (accounted for $9.0\%$). It is same to other research results.

The purpose of this study was to investigate sodium consumption and related psychosocial factors among hypertensive patients and normal adults through questionnaire development. The Theory of Planned Behavior provided the basis for the study. The mean blood pressure of subjects was 117. 1 mmHg/78.55mgHg in normal adults(N-218), 159.65mmHg/102.05mmHg(systolic/diastolic) in hypertensive group(N=219) and the sodium consumption was 5219.4${\pm}$1821.3mg in normal adults and 4631.4${\pm}$1749.1mg in hypertensive group. The results of Multiple logistic regression analysis showed that the odds of being hypetensive group were increasd as subjects felt that dalty food (OR=1.5) (OR=0.8). The odds of beign hypertensive group increased as subject received more support. With respect to perceived control, the odds of being hypertensive group were increased as subjects felt more confident in contolling salty intake when spouse likes to take salty food(OR=1.4). In contrast, subjects felt less confident in contolling sodium consumption when they took medicine(OR=0.8). Study findings revealed that all three factors, attitudes, subjective norms, and perceived control contributed to the model for explaining intentions, with subjective norms being most important. This findings provided the empirical evidence for the TPB in explaining salt intake. This study suggest that educational interventions for hypertension patients focus on changing sodium consumption through changing attitude toward high sodium consumption, subjective norms, perceived control over reducing sodium consumption of specific situations, specially subjective norms and perceived control. In addition, interventions may include strategies to change attitudes toward sodium consumption by helping hypertensive patients realize negative beliefs and modifying positive beliefs and to elicit and maintain subjective norm from doctors, family and neighbors, and to increase control beliefs for reducing sodium consumption.(Korean J Nutrition 33(8) : 833-839, 2000)

새롭게 제안된 다이아그리드 구조 시스템은 경사진 기둥을 통해 구조물의 중력하중과 횡력을 모두 저항하는 시스템이다. 하지만 현재 내진설계 기준은 새로운 구조시스템에 대한 적절한 반응수정계수가 없다. 이에 새로운 시스템의 반응수정계수를 포함한 내진설계시 고려되는 내진성능계수들을 산정하기 위해 ATC-63(안)이 새롭게 제안되었다. ATC-63(안)에서는 구조 시스템의 여러 변수에 의해 다른 값을 가지게 되는 반응수정계수를 보완하기 위해 붕괴여유비를 함께 고려하여 건물의 내진성능을 판단한다. 본 논문에서는 4층에서 36층의 서로 다른 높이의 대각가 새 구조물을 설계하여 ATC-63(안)의 방법론에 따라 비선형정적해석과 동적해석을 통해 대각가새 구조의 내진성능계수를 평가하였다.
