Purpose: The purpose of this study was to investigate the relationship between health locus of control(HLOC) and eating behavior in obese middle school girls. Method: The sample consisted of 170 obese middle school girls in Seoul. Result: 1. The average scores of HLOC were HLOC-Internal ; 4.11, HLOC-External ; 2.45, HLOC-Chance ; 2.09. 2. The average scores of eating behavior factors were Disinhibition ; 2.69, Dietary Restraint ; 2.67, Hunger ; 2.55. 3. The HLOC-Internal and eating behavior(dietary restraint and hunger) were correlated positively. The HLOC-Chance and disinhibition was correlated positively. But HLOC-Chance and dietary restraint was correlated negatively. The HLOC-External and eating behavior(dietary restraint, disinhibition and hunger) were correlated positively. 4. There was not a significant difference in HLOC depending on the demographic characteristics(grade, degree of obesity, father & mother's body shape, existence of obese sibling). There were significant differences in HLOC-Internal and HLOC-External according to thinking about oneself who is obese or not. 5. There was not a significant difference in eating behavior depending on the demographic characteristics(grade, degree of obesity, father & mother's body shape, existence of obese sibling, perception of oneself as a obese). Conclusion: This study has shown a correlation between HLOC and eating behavior. As a result of these findings, clinical and school nurses should be involved in management and counselling of obese girls concerning individual health locus of control and eating behavior.

This paper considers a firm that operates make-to-stock and make-to-order facilities in successive stages. The make-to-stock facility produces components which are consumed by the external market demand as well as the internal make-to-order operation. The make-to-order facility processes customer orders with the option of acceptance or rejection. In this paper, we address the problem of coordinating how to allocate the capacity of the make-to-stock facility to internal and external demands and how to control incoming customer orders at the make-to-order facility so as to maximize the firm's profit subject to the system costs. To deal with this issue, we formulate the problem as a Markov decision process and characterize the structure of the optimal inventory allocation and customer order control. In a numerical experiment, we compare the performance of the optimal policy to the heuristic with static inventory allocation and admission control under different operating conditions of the system.

온실의 차광설계에 필요한 기초자료를 제시하기 위하여 온실모형과 실험온실을 이용하여 외부차광재의 적정 설치간격 분석, 차광재별 광투과율 분석, 차광율에 따른 온실내부온도의 변화 분석, 차광의 온실내부의 지온변화에 미치는 영향 분석 및 외부차광과 내부차광의 차광효과 비교를 실시하였다. 외부경사차광시 온실 지붕과 차광재의 설치간격은 10~30 cm에서 차광효율이 가장 좋은 것으로 나타났으나 환기창의 개폐를 위한 공간이 필요하지 않는 온실에서는 10cm 정도이면 충분한 간격이 될 것으로 판단된다. 경사차광의 온도차가 수평차광보다 높게 나타나 무환기 상태에서는 경사차광의 차광성능이 수평차광보다 더우수함을 알 수 있었다. 차광재 제작사에서 제시한 투과율과 실제 온실에서 계측한 투과율이 상당한 차이가 있으므로 차광재를 온실의 온도환경제어 목적으로 이용하고자 할 경우에는 차광재의 투과율을 미리 측정하여 검증할 필요가 있었다. 자연환기와 무환기 조건 모두에서 85% 차광온실이 55%차광온실 보다 최대 약 4$^{\circ}C$, 평균 약 2$^{\circ}C$ 정도의 승온억제효과가 더 있었다. 차광온실 내무의 지온변화는 차광율과 차광방법에 따른 차이는 매우 작았으나 무차광온실과는 큰 차이가 있었기 때문에 온실내부의 지온변화는 차광율과 차광방법 보다는 차광의 유무에 큰 영향을 받는다는 사실을 알 수 있었다. 50%인 차광재가 55% 차고아재보다 광투과율이 높음에도 불구하고 차광율 50%인 외부차광온실이 차광율 55%인 내부차광온실보다 승온억제효과가 더 우수한 것으로 분석되었다. 이러한 결과는 외부차광시 차광재가 흡수한 열이 온실내부로 전달되지 않을 뿐만 아니라 천장을 통한 환기효율이 내부차광보다 양호하기 때문인 것으로 판단되었다.

This study was made to suggest the nursing strategies for promoting the behaviors about bone mass health behaviors in order to prevent middle aged women's osteoporosis. This study was a descriptive-correlational design that also concerned to the types which improve bone mass promoting behaviors by inspecting patterns of health locus of control method out of recognizable variables of health improving models influencing on these bone mass promoting behaviors. For these purpose, data were collected by self reported questionnaire in middle school, from 158 women living in Seoul. The measuring tools used in this study about bone mass promoting behaviors and multidimensional health locus of control, were developed by author on the basis of literature review and analyzed by SPSS-PC window, into pearson's correlation, ANOVA, multiple regression, cluster analysis. Data was analyzed as follows. 1. 6 Multidimensional health locus of control scale clusters were existed. : a)cluster I (pure internal), b)cluster II(pure chance), c) cluster III(Believer in control), d), cluster IV(Type VI), e)cluster V(yea sayer), f) cluster VI(nay sayer). There were no findings of the powerful others external cluster and double external cluster. 2. The higher the value of internal health locus of control was, the better the bone mass promoting behaviors were(r=.2891, $p=.00^{**}$). The higher the value of chance external health locus of control was, the worse the bone mass promoting behaviors were(r=-.1367, $p=.00^{**}$). 3. On the basis of these relationships, 6 clusters were significantly different in the bone mass promoting behaviors(F=2.27, $p=.05^*$). The value of bone mass promoting behaviors was ranked the order of type VI>believer in control>pure internal>yea sayer>nay sayer>pure chance external highly. 4. Bone mass promoting behaviors were not significantly different as to age. Suggestion. Based on the results from the study, I would like to make some suggestions as follows. 1) To delay the loss of bone mass in middle aged women, the study on the cluster of the multidimensional health locus of control should be conducted repeatedly. 2) The tool of multidimensional health locus of control should be developed through a qualitative method adjusted on Korean' health culture.

This paper deals with modeling and analysis fer the landing motion of a human-body model. First, the dynamic model of a floating human body is derived. The external impulse exerted on the ground as well as the internal impulse experienced at the joints of the human body model is analyzed. Second, a motion planning algorithm exploiting the kinematic redundancy is suggested to ensure stability in terms of ZMP stability condition during a series of landing phases. Four phases of landing motion are investigated. In simulation, the external and internal impulses experienced at the human joints and the ZMP history resulting from the motion planning are analyzed for two different configurations. h desired landing posture is suggested by comparison of the simulation results.

Locals of Control is considered one of the main imporment factors on responsible environmental behaviors(REB). It is defined as an individual's perception of his or ha ability to bring about change through his a her behavior. This psychological construct is divided in two, external and internal. Internal locus of control(ILOC) is imporment as predictor for responsible environmental behaviors. This study was conducted to investigate the Locus of Control and relations with REB in Undergraduate Students. The data were collected mainly through questionnaires and a total of 157 responded questionnaires was analyzed for the study. The statistical methods used in this study were frequency, percentile and correlation. The major findings of this study were (1) Most of undergraduate students had internal locus of control(75.2%). (2) According to region, rural students showed high levels in ILOC and REB.

The purpose of the present study was to examine the relationship between children's locus of control and their parents. In addition, this study investigated socio-demographic variables of locus of control in children and their patents. The subjects of this study were 269 elementary school children in the 5th and 6th grade and their parents. To assess children's locus of control, the inter -external locus of control scale developed by H.K. Lee(1980) was used. The locus of control scale designed by J. W. Jo(1989) was administered to parents. The data of the study were analysed with t-test, one was ANOVA and Scheffe's test. Also, Pearson's correlation coefficient was computed. The results of this study were as follows. 1)There were significant differences in children's locus of control according to the children's sex, parent's educational background and family income. Boys were more internal than girls. Children with parent who had higher educational backgrounds were more internal than others. Also, children in higher family income were more internal those in lower educational background and family income. Also parents with religion were more internal than those without religion. 3)children's locus of control was significantly correlated with their parents . Paternal locus of control was significantly correlated with their daughter's and maternal locus of control with their sons'.
