Human factors have been considered the primary reason of marine accidents. Especially, the collision between vessels is mostly mused by human behavior. However, there have not been many researches to clarify the reason of marine accidents mused by human factors quantitatively. In order to understand human factors and to enhance safe navigation systematically, using a full mission ship-handling simulator, we've investigated the characteristics of avoiding behavior taken by mariners. Further in order to apply the characteristics more widely and effectively, it's necessary to formulate the standard behavior for ship-handling in the condition of collision avoidance. Is this study, therefore, we intended to propose the concept to model the mariner's standard behavior on the handling of collision avoidance as the first step. As a result, we confirmed the contents of information processing in ship-handling that mariner's generally taking to avoid collision.

This study was a descriptive research to investigate the health promotion behavior and health status based on Korean adult's constitution. The subjects for the study were 96 adults who were the residents either in Seoul or Taegu city. The instruments used for this study included a survey of general characteristics, health promotion behavior and health status. The data were analyzed using t-test, ANOVA, Pearson correlation coefficient and Scheffe method as post hoc test. The results of this study were summarized as follows : 1) There was no significant difference on the health promotion behavior and health status by constitutions. But, in the relationship between five factors of the health promotion behavior and constitution, there was significant difference on health responsibility by constitutions(F=3.31. P=.041). According to the scheffe test, Taeumin group performed better behavior for the health promotion than soyangin group. 2) Health promotion behavior was significantly related to health status (r=-.24, P=.025), suggesting that the person with high health promotion behavior get higher health status scores. 3) In the relationship between general characteristics variables and health promotion behavior, there were significant differences in education(F=3.12, P=.031), economic status(F=4.09, P=.021), religion (F=3.12, P=.031). The level of health promotion behavior of high educated persons and high economic status persons was high. The persons who believe in Catholicism performed better behavior for the health promotion than the persons who don't get religion. Based on these results, to determining and fully understanding client's constitution are the foundations of Eum-Yang and personal character. Therefore, we have to consider the constitution when we provide nursing care. When we consider the differences of health promotion behavior according to constitution, we can provide the client with the kind of nursing care and health education to satisfy their demands.

The 583 employees as subject for empirical analysis were selected by cluster sampling method in Banwol & Sihwa Industrial complex in Ansan area. This study shows the followings; 1. In the group where the task is unstructured and the subordinate's ability is high, the achievement-oriented and participative leader behavior have positive impact on the subordinate's expectancy. 2. In the group where the task is unstructured and the subordinate's ability is low, the directive leader behavior has positive impact on the subordinate's expectancy. 3. In the group where the task is structured and the subordinate's ability is high, the supportive leader behavior has positive impact on the subordinate's expectancy. 4. In the group where the task is structured and the subordinate's ability is low, only supportive leader behavior has positive impact on the subordinate's expectancy, and the directive leader behavior has no significant impact. 5. The subordinate's need for growth has a strong moderating effect in the relationship between leader behavior and job satisfaction. Finally this study indicates the implication for future theoretical and empirical development.

This study is to understand the determinants affecting women's fertility behavior (additional fertility plan) using the Korean Longitudinal Survey of Women & Families of 2007. Patterns of married women's life courses are divided into five groups depending on family role and economic activity: family-centered (no work experience) type, latent M type, M type, work-family reconciliation type, and first job entry type. This study performs a binomial logistic regression analysis and the key findings from the study are summarized as follows. First, five distinctive patterns show the different composition: family-centered type (4.5%), latent M type (69.6%), M type (10.4%), work-family reconciliation type (7.4%), and first job entry type (8.1%). Second, socio-economic characteristics, husband characteristics, and value characteristics are statistically significant to additional fertility behavior ; however, institutional character is not significant. Finally, significant factors affecting additional fertility plans vary in different patterns of life courses. Based on these results, this study suggests some policy implications and future research directions.

This paper describes the macroscopic behavior and atomization characteristics of the high-pressure gasoline swirl injector in direct-injection gasoline engine. The global spray behavior of fuel injector was visualized by shadowgraph technique. The atomization characteristics of gasoline spray such as mean diameter and mean velocity of droplets were measured by the phase Doppler particle analyzer system. The macroscopic visualization and experiment of particle measurement on the fuel spray were investigated at 7 and 10 MPa of injection pressure under different spray cone angle. The results of this work show that the geometry of injector was more dominant over the macroscopic characteristics of spray than the fuel injection pressure and injection duration. As for the atomization characteristics, the increase of injection pressure resulted in the decrease of fuel droplet diameter and the atomization characteristics differed as to the spray cone angle. The most droplets had under $25{\mu}m$ diameter and for the large droplets(upper $40{\mu}m$) as the spray grew the atomization presses were very slow. Comparison results between the measured droplet distribution and the droplet distribution functions revealed that the measured droplet distribution is very closed to the Normal distribution function and Nukiyama-Tanasawa's function.

The purposes of this study was to analyze the effects of household characteristics and financial variables on financial management behavior and financial solidity. The major results could be summarized as follows. First, Debt management behavior and risk management behavior reveled a higher score than any other financial management behaviors. The main determinants of financial management behavior were financial communication and financial attitudes. The more positive financial attitudes and the more financial communication were, the better the financial management behavior followed. The set of households characteristics variables accounted for 2% of the variance in the financial management behaviors. But the addition of financial related variables resulted in an R2 change of 33%. Second, the financial solidity by median was 4.10. It means that usuable net asset is four times higher than the total amount of risk. Household head\`s age, financial attitudes and financial management behavior were the variables affecting the financial solidity.

Factor analysis of data collected from 336 elementary school children provided difficuitness and susceptibility as the temperament factors, and affect and control as the nurturing factors. Results showed that non-susceptible children with low controlling mother perceived their cognitive competence positively while highly susceptible children showed no differences in their self-competence by mothers' controlling behavior. Perceived cognitive competence of susceptible boys and of susceptible 3rd graders were low when their mothers asserted low control. Thus, mothers' controlling behavior supported perceived cognitive competence in highly susceptible boys and 3rd graders. That is, the effect of mother's behavior on child's self-competence was moderated by child's characteristics. These results partially supported the Conditional Model.

This paper describes the characteristics of injection rate and macroscopic behavior of fuel spray injected from common-rail type diesel injectors with different nozzle geometries. The injection rates according to the nozzle geometries were measured at different energizing duration of the injector solenoid and injection pressure by using the Bosch's injection rate meter based on the pressure variation in the tube. The spray behaviors injected from the different nozzles were visualized using the spray visualization system composed of an Ar-ion laser, an ICCD camera, and a synchronization system at various injection and ambient pressures. It is revealed that VCO nozzle has higher spray tip velocity at the early stage of injection duration and wider spray cone angle than the mini-sac nozzles. Also the spray cone angle is increased with the increase of nozzle diameter.

This study was conducted to understand the Ramyun's selection attributes of Korean adults and examine differences in demographic characteristics and meal intake behavior among three groups of samples divided based on the Ramyun's selection attributes. Self-administered questionnaires were completed by 702 adults, and data were subjected to frequency analysis, chi-square analysis, factor analysis, reliability tests, cluster analysis, and discriminant analysis using SPSS. The results of the study were as follows. The Ramyun's selection attributes for Korean adults investigated were food quality (four variables), price (three variables), and company reliability (four variables). Cluster analysis resulted in the subjects being divided into three groups according to their Ramyun's selection attributes, a high-selection group, mid-selection group, and low-selection group. Three groups of samples classified by Ramyun's selection attributes differed based on demographic characteristics (gender and education level) and meal intake behavior (meal numbers, reason for meal, meal time, and meal size).
