This study investigated the relationship between personality characteristics of individual and adjustment in the mid-life. The subjects of the study consisted of 374 married persons(185 men and 189 women) who live in Seoul and are 40 to 50 years old and whose last child is in middle school. Bem's short form BSRI, Rotter(1966)'s Internal-External Scale and Hayes & Stinnett(1977)'s MYLSS were used as measurements tools. The major results of the study were summarized as follows ; 1) While sex-role identity of middle aged men appeared in the follwing order ; Androgynous, masculine, undifferentiated, feminine, sec-role identity of middle aged women appeared in the following order ; Undifferentiated, androgynous, feminine, masculine. Both men and women had the moderate scores on the locus of control. The middle aged expressed a moderate level of life satisfaction with middle aged men reporting significantly a higher life satisfaction than did women. 2) Socio-demographic variables such as age, education, occuption and income have turned out to be significant on the life satisfaction of middle aged men. As for the life satisfacton of middle aged women, age, education, husband's occuption and religon had significant influences However, employment status of women, family structure, marital duration, number of child, status of last child, status of first child had no significant influences on Mid-life satisfaction. 3) Mid-life satisfaction of men and women was influenced significantly by sex-role identity and internal-external locus of control. Those men described as masculine and those women androgynous in the sex-role identity had the highest life satisfaction. On the other hand those of undifferentiated in the sex-role identity had the lowest life satisfaction. High levels of internal control were associated with high levels of life satisfaction. 4) The variables affecting the life satisfaction of middle aged men and women were education, income, sex-role identity, internal control. These 4 variables explained 27% of the life satisfaction of middle aged men and 24% of the life satisfaction of middle aged women.

The direct-drive servo valve(DDV) is a kind of one-stage valve because the main spool valve is directly driven by the dc motor. Since the DDV structure is simple, it is less expensive, more reliable, and offers a reduced internal leakage and a reduced sensitivity to fluid contamination. The control system of the DDV is highly nonlinear due to a current limiter, a voltage limiter, and the flow-force effect on the spool motion. The shape of the step response of the DDV-control system varies considerably according to the magnitudes of the step input and the load pressure. The system-design requirements mean that the overshoots should be less than 20%, and the errors at 0.02s should be less than 2%, regardless of the reference-step input sizes of 1V and 5V and the load-pressure magnitudes of 0MPa and 20.7MPa. To satisfy the system-design requirements, the PID-controller parameters of $K_c$, $T_i$ and $T_d$, and the derivative-feedback gain of $K_{der}$ are designed using the root locus and manual tuning.

Purpose: This study sought to investigate health behavior (HB) and its affecting factors based on Anderson's behavioral model in Lao People's Democratic Republic (PDR). Also, it attempted to identify the mediation of the health locus of control (HLC) between HB and the affecting factors. Methods: Secondary data from 694 people without noncommunicable diseases (NCDs) from a survey conducted by the Ewha Womans and the Laos University were used. The measurements included predisposing, enabling, and needs factors, HLC, HB (current non-smoking, low-risk drinking, physical activity, fruit and vegetable consumption, medical checkup). The mediating effect was analyzed using Baron and Kenny's method and the Sobel test. Results: Predisposing (gender, educational level, ethnic), enabling (social support, item ownership in household) and the needs factors (body mass index) were affecting HB. Internal HLC had a positive influence on HB. The stronger the others and chance HLC, the lower the HB. Chance HLC mediated the relationship between the educational level and HB. Conclusion: There is a need to recognize the importance of chance HLC as a mediator between the educational level and HB. Through this result, high-quality nursing education for the prevention of NCDs should be developed considering the impact of chance HLC.

This study intended to examine closely the reasons which influence the health status and to health behavior of teenagers and plan the development of the school health education. The subject of this study was the boys, and girls' high school students in Chonguy city. The number of them was totally 632 and the period was from July 9 to 14, 1990. 1. The Health Status of Teenagers. I have examined closely the health status of teenagers. They answered they continued to go to school. ever though the majority of teenagers had troubles in their sleeping and felt sick As for one's health, most of teenagers were in a good condition and were sometimes worrying about their health condition. 2. The Degree of Interest and Responsibilities of Teenagers for Their Own Health. In the responsibility of teenagers for their own health the answer, 'my health depends on my taking care of it', had the highest grade, 4.67. And the answer, 'I am in a good health condition because I have taken of my health very well', had the lowest average, 4.1. In the degree of interest of teenagers for their own health, the problem of studying had the highest degree, 4.48 and the use of drugs, the smoking behavior, masturbation, the drinking behavior and the birth control were the lowest degree. 3. The Health Behavior of Teenagers. In this part, teenagers performed about 64 percent's health behavior on the point of 3.37. 4. The Comparison of the Health Behavior, the Health Responsibility and the Health Interest of the Subject According to the General Characteristics. The results were as follows: 1) There are significantly different in the health behavior according to sex (t=6.23, p<.001), smoking experience (t=5.33, p<.001), living place (t=5.09, p<.001), ranking of brothers (F=4.19, p<.01), economic situation(F=6.57, p<.001). 2) There is significantly different in the health responsibility according to sex(t=2.31, p<.05), experiencd by disease(t= 1.92, p<.05). 3) There are significantly different in the health interest according to the chronic disease experience of family (t=3.29, p<.001), smoking experience(t=2.71, p<.01). 5. The Correlation of the Health Behavior, the Health Responsibility, the Health Interest and the Health Locus of Control of the Subject. The health behavior showed the positive correlation with the health responsibility (r=.2906, p<.001), and the health responsibility showed the positive correlation with the health interest (r=.0938, p<.01). Also the health behavior showed the positive correlation with powerful others health locus of control (r=.2606, p<.001), and internal health locus of control (r=.2023, p<.001), the health responsibility showed the positive correlation with internal health locus of control (r=.4541, p<.001), and chance health locus of control(r=.1352, p<.001), and the health interest showed the positive correlation with internal health locus of ccntrol (r=.0920, p<.001), powerful others health iocus of control (r=.1907, p<.001 chance health locus of control (r=.1191, p<.01). On the basis of the above result, we can find the fact that the interest of teenagers for their own health is increasing. And so, it is necessary for the school health management to establish the new curriculum which strengthens the health education for the planning of one's desirable health management. Besides we need efforts to develop the standard scale through the analysis of all reasons which influences the tenagers' health status and health behavior.

The purpose of this study is to reduce the costs required to proactively prevent the turnover intention by the results of personality type of locus of control. which is the behavioral outcome of the members of the organization. Based on this problem consciousness, the present study focused on the personal characteristics of the members of the organization in the enterprise. Among the individual characteristics, the intentions, which are distinct from others, are called personality, Focusing on the locus of control among these types of characteristics of the organization members, the study about how these control positions affect their job involvement and their turnover intention. The results validated in this study are summarized as follows. Among the personality types of the organization's members, internals are found to have higher job involvement than externals. In addition, it was found that internals among the personality types of the members of the organization lower the meaning of turnover intention than external member. In order to overcome uncertain management environment and create and sustain a competitive advantage in the organization, management has a weight-oriented trend and Increasing job involvement in organizational members and lowering their turnover intention will lead to continued productivity, among other things, important management items that managers and managers should pursue. Given these aspects, it is deemed necessary to analyze the personality aspects of the members of the organization and to transform and manage a new management mindset that leads to the enhancement of the personality as an internal rather than an external one and the task immersion of the members of the organization based on it.

The goal of this study is to compare entrepreneurial orientation of both countries' students and to compare the effect of individualism on developing entrepreneurial orientation of both countries. In order to achieve this goal, this study will conduct two analysis. Firstly, the comparative study on entrepreneurial orientation of both students will be implemented by conducting F-test and t-test. Secondly, the regression analysis between an independent variable - individualism - and dependent variables - innovativeness, internal locus of control, and entrepreneurial orientation - will be conducted in order to compare the effect of individualism on developing entrepreneurial orientation. Prior to implementation of two analysis, this study has implemented the survey to Korean and Chinese university students to estimate entrepreneurial orientation and a cultural variable to influence entrepreneurial orientation. The question of survey is divided into two parts - individual entrepreneurial orientation including internal locus of control and innovativeness and a cultural variable, individualism. As other precedent comparative studies of Chines and Korean potential entrepreneurship concluded, Chinese students have shown higher entrepreneurial orientation than Korean students. However, on the contrary to prior studies on cultural factors and entrepreneurship, only Chinese students' entrepreneurial orientation is influenced by individualism. Any dependent variables of Korean students were not affected by individualism variable.

This Meta-Analysis of 18 studies was conducted to determine the magnitude of th relationship between health promotion behavior and each of explanatory variables. The studies were measured using Health Promoting Life Style(HPLP) developed by Walker and others based on Pender's definiton of health promoting behavior. The sample was collected by searching for The Journal of Korean Academy Nursing Society, The Journal of Korean Women's Health Nursing Academic Society,The Journal of Korean Academic Society of Adult Nursing, Journal of Korean Community Nursing, The Journal of Fundamentals of Nursing, The Journal of Korean Nursing Administration Academic Society, The Korean Journal of Child Health Nursing, The Journal of Korean Psychiatric Academic Society, the dissertations for mater degree or doctoral dissertations for the period from 1980 to 1998. The explanatory variables measured more than 2 times in studies were self-efficacy, perceived health status, self-esteem, internal, powerful-others and chance dimensions of health locus of control, perceived benefits, hardiness, wellbeing and clinical demensions of health concepts, and quality of life(life satisfaction). Effect sizes were calculated by unweighted mean r, weighted mean r by sample size and weighted mean r by quality index score after homogeneity test. The mean r effect size indicator range of each predictor variable were as follows; quality of life (0.50- 0.52), self-efficacy (0.46-0.47), hardiness (0.42-0.44), self-esteem(0.41-0.43), health locus of control- internal(0.32-0.34), health locus of control- powerful others (0.25-0.31), perceived health status(0.18-0.19) and clinical dimensions of health concepts (0.16-0.17).

Health promoting behaviors of an individual are affected by various variables. Recently, there has been a growing concern over important health problems of the middle aged women. Physiological changes in the middle aged women and their responsibility for family care can result in physical and psychological burden experienced by middle aged women. This study was designed to test Pender's model and thus purpose a model that explains health promoting behaviors among middle-aged women in Korea. The hypothetical model was developed based on the Pender's health promoting model and the findings from past studies on women's health. Data were collected by self-reported questionnaires from 863 women living in Seoul, between 20th, April and 15th, July 1995. Data were analyzed using descriptive statistics and correlation analysis. The Linear Structural Relationship(LISREL) modeling process was used to find the best fit model which assumes causal relationships among variables. The results are as follows : 1. The Overall fit of the hypothetical model to the data was good expect chi-square value（GFI＝.96, AGFI＝.91, RMR＝.04）. 2. Paths of the model were modified by considering both its theoretical implication and statistical significance of the parameter estimates. Compared to the hypothetical model, the revised model has become parsimonious and had a better fit to the data expect chi-square value（GFI＝.95, AFGI＝ .92. RMR＝.04）. 3. Some of modifying factors, especially age, occupation, educational levels and body mass index (BMI) are revealed significant effects on health promoting behaviors. 4. Some of cognitive-perceptual factors, especially internal health locus of control, self-efficacy and perceptive health status are revealed significant effects on health promoting behaviors. 5. All predictive variables of health promoting behaviors, especially age, occupation, educational levels, body mass index(BMI), internal health locus of control, self-efficacy ＆ perceptive health status are explained 20.0％ of the total variance in the model.

For the purpose of turning learners' locus of control into internal-controllable variables, counseling materials were developed, and attribution counseling was given. The counseling effects were practically confirmed by way of teaching and evaluation in the actual classes, and furthermore the efforts to provide learners with successful experiences in learning were repeatedly made. As a result, the conclusions are as follows: 1. The procedure of Individual counseling for learning attribution based on individual standard grades and data of the variable order of merit apparently shows learners that if learners are to try their best in learning, they will surely go far in terms of learning in the near future. 2. The procedure of Individual counseling for teaming attribution based on achievement distribution in individual behavior-oriented fields suggests to learners that how to learn is as important as how much effort they make. Surely enough, learners are required to make more effective and efficient efforts, considering their own learning abilities. 3. With the above 1, 2 procedures involved, learners have attributed locus of causality in achievement to their internal-controllable causes. 4. With preparatory assignments according to learner's abilities provided, even slower learners came to be assured that their constant efforts could give rise to success in learning achievement. 5. Above all, it was confirmed that the learners' struggling attitude might well have a significant correlation with achievement success. The learners who are willing to attribute locus of causality in achievement to their internal-controllable causes or strenuous efforts and intrinsic motivation tend to be convinced that they can address themselves to whatever faces them, so they can set up specific learning goals fit for their abilities. Accordingly, they will bit by bit acquire successful experiences (often called 'Aha' experiences) and in turn, feeling the senses of self-efficacy and self-esteem enough to push their efforts even further, they can grow to form a positive self-concept. With one successful experience after another fed back into learners, they are gradually motivated to bring the oncoming achievement expectation to a higher level. To conclude, it is necessary that instruction leading to internal-controllable attribution should be provided, inducing learners to recognize success and failure in learning achievement as a result of their strenuous efforts.
