  • The purpose of this study was to investigate the levels of knowledge and behavior towards food hygiene among child consumers, examine the factors influencing them, and analyze the causal relationship between them. The data were collected from 521 elementary school students in Youngnam area by a self-administered questionnaire. Frequencies, Pearson's correlation analysis, multiple regression analyses, and path analysis were conducted by SPSS Windows. The results from this study were as follows. First, the level of knowledge towards food hygiene was not particularly high, and the level of behavior was somewhat more than the average. Second, the factors influencing the level of knowledge towards food hygiene were school record (upper and middle), and concerns about food hygiene. In addition, concerns about food hygiene, the frequency of food hygiene education in the family, and the level of knowledge towards food hygiene had an effect on the level of behavior towards food hygiene. Third, in the analysis of the causal relationship between the knowledge and behavior towards food hygiene, school record indirectly influenced the behavior towards food hygiene, and the frequency of food hygiene education in the family directly affected the behavior towards food hygiene. On the other hand, concerns about food hygiene had direct and indirect influence on the behavior towards food hygiene. In addition, the knowledge towards food hygiene showed a direct effect on the behavior towards food hygiene. These results imply that knowledge towards food hygiene is a very important factor to improve the children's behavior towards food hygiene and that parents' concerns and guidance for children are needed.

  • The purpose of this article is to examine the effects of item parceling on the consistency of significance testing of the causal parameters with regard to the relationship between the relevant constructs, as well as the effects of the item parceling on the goodness-of-fit indices of LISREL's general models. Most of the researchers' major purpose of using structural equation modeling (SEM) is to test their research hypotheses associated with the causal parameters. Therefore, we investigated three general models of LISREL, rather than the frequently used confirmatory factor analytic (CFA) models by many other researchers. The results of the study showed that there was a high level of consistency in the calculated test statics of causal parameters between the item-parceled solutions and the item-level solutions, and that the item-parceled solutions had better goodness-of-fit indices, such as GFI, AGFI, CFI, and NFI, than the solutions at the item level. However, in terms of RMSEA, there was no such tendency.

  • The purpose of this study was to investigate the effect of police officers' participatory decision-making, supervisory quality and attitude, organizational justice on job satisfaction focused on mediating effect of work-life conflict. As a result of analysis of 185 police officers, the results were as follows. The causal relationships between participatory decision-making, organizational justice and work-life conflict, the ones between supervisory qualities and attitude, organizational justice, work-life conflict and job satisfaction, all of them reached the significance levels, not the causal relationship between supervisory qualityand attitude work-life conflict. Thus, the results for the interaction have shown, participatory decision-making and organizational justice and work-life conflict have negative influences on work-life conflict respectively, and supervisory qualities and attitude conflict, organizational justice conflict, work-life conflict have effect on job satisfaction with positive and negative effect. The Sobel-test showed that the Sobel-test statistic of the mediating effect of work-life conflict on causal relationships between organizational justice and job satisfaction is significant, but not in the mediating effect of work-life conflict on causal relationships between supervisory qualities and attitude and job satisfaction. According to the analytical results, work-life conflict is an important factor that can improve police officers' job satisfaction in the public organizational context with an open-oriented- system and culture for employees' participation in the process of decision making and equality and fairness for organizational management. It is also noted that work-life harmony for employees may be incompatible with the supervisor's perception of the work-oriented or prioritized-way in hierarchical organizations like police agencies.

  • The collisions at sea among marine casualties are not reduced as the tonnage and speed of ship's increase as well as the traffic quantity increase at sea, in spite of the improvement of nautical equipment, enforcement of crew's education and training as well as improvement of quality standard according to the implementation of ISM code. The measures to prevent the collisions at sea are simple, and are composed of six stage.: The first stage is that the officer on duty detect the target from his eye or radar information. The second stage is determining the type and kind of target-ship. The third stage is target tracking; calculation of target speed, course, CPA and TCPA from radar information or visual check. The fourth stage is determination of vessel in danger after calculation of third stage. The fifth stage is the judgement of situation if own ship is stand-on or give way vessel according to the 1972 COLREG. The last stage is to carry out proper action according to 1972 COLREG, under the circumstances. But by the case, the situations are so different under the different external conditions; for example, natural/navigational conditions, crew's human factors, ship's particular, rule or regulation, management system on board, the condition of watch keeping. Therefore the reasons and casualties are so complicated. This study aims to investigate the collision casualty at sea which needs to clarity all these causal factors of afore-mentioned, and to analyze the causes of problems so as to utilize them to establish the measures of preventing marine accidents. This study, described the concepts of causal factors into three groups; environmental factor, and company/on board management system and navigator's act. Also described how to investigate and analyzes the casual factors. Even though it was described in this paper how to detect the causal factors and reasons of collisions, and how to analyze the inter-relation of each causal factors, it is necessary to do further study how to analyze between the liability of concerned parties and the casual factors involved.

  • Objective : To evaluate factor XII deficiency in patients with recurrent spontaneous abortion and its relation to aPTT. Material and Method: Factor XII was analyzed by clotting method. Results: Of 70 patients with recurrent spontaneous abortion, there were 35 cases of factor XII deficiency. Among them, there were only 3 cases of prolonged aPTT. Conclusions: It is still unclear whether factor XII deficiency is related to recurrent spontaneous abortion. Molecular approaches should be used to understand further the causal relationship. But based on this result, in the workup of patients with recurrent spontaneous abortion, factor XII should be included. aPTT is not likely to represent the abnormality of factor XII.

  • There are an increasing emphasis on affective domain, for example interest or belief, in science education. But decreasing interest on learning science and tendency to avoid science-related job are serious problems of secondary science education, especially in case of vocational high school students. However there are few researches for vocational high school students. In this study, preference for science is assumed to be a multidimensional property that reveals ones' behavioral volition and valuation as well as emotional response upon learning science. To investigate vocational high school students' preference for science and its causal factors, a Likert style questionnaire was developed through factor analysis. Students' preference for science was analyzed by 3 categories, and its causal factors are investigated by path analysis using structural equation model.

  • The purpose of this study is to verify the factors that affect the fear of crime by applying the risk interpretation model. Especially, whereas previous studies have not proven micro individual factor that the risk interpretation model had presented, This study includes micro individual elements such as neighborhood factor, perceived risk of crime, fears of crime as main variables. This study utilized secondary data of the National Crime Victimization Survey 2012, conducted by the Korean Institute of Criminology. In this study, multiple regression analysis of two stages and Sobel Test were conducted for verifying the individual influence of each independent variables and identifying the causal relationship between the variables set out in the risk analysis model. As the result, it appeared that the higher level of perceived risk of crime, neighborhood factor, crime experience, education, income cause the higher degree of the fear of crime. On the other hand, the lower degree of age was found to induce the higher level of the fear of crime. In addition, female showed the higher degree of the fear of crime than man. The causal relationship between the variables set out in the risk interpretation model was presented significantly in all variables, except for education.

  • This study describes the relation of physician's income and price of medical service and social welfare through microeconomic view, reviews the literature of influencing factor on physician's income, and it describes general distribution of physician's income, and analyzes influencing factor of physician's income. A total of 844 persons responded to the mail survey, through stratified sampling by 23 branches of medical society in Korean RBRVS study. The design of the study is cross sectional study, and the unit of analysis is a physician. To examine the change of average income per month, multiple regression was used to test the change according to physician's characteristics, demographic characteristics, scale of clinic, average intensity of ordinary work, and specialty. The major findings of this study are as follows; 1. As for self-employed physicians, the difference of average income per month among specialties was mcreased \4,850,000, but the difference was \6,020,000 under the control of control variables. 2. The number of average out-patients per month and number of nurses and nursing aides significantly positively associated, and average income per month was significantly higher for physicians who had sick-beds than physicians who had no sick-beds. In conclusion, the number of out-patient and number of nurses and nursing aides is the major influencing factor, and the difference of average income per month among specialties existed in self-employed physicians. So this study suggests basic hypothesis that the price of medical service and supply of physician by specialties are not pertinent. Being a cross-sectional study, this study can not suggest causal explanations. In the future, further study is needed for causal explanations.

  • The current study attempts to expand our understanding of the determinants of energy-saving technology (EST) use by focusing on the individual aspects of environmental behaviors. This study integrates the hedonic, normative, and gain goals to explain the causal relationship between users and EST use. By adopting Goal-Framing Theory, this study proposed three individual goal frames in the environmental context: hedonic (perceived pleasurability), normative (social norms), and gain goals (legislative pressure and economic factor). Partial Least Square (PLS) was used to analyze the data from 104 respondents. Eight of the ten hypotheses were strongly supported. We found that social norms, perceived pleasurability, economic factor, and legislative pressure had positive and significant effects on attitude to EST use. Interestingly, we found that media influence did not have a severe effect on perceived pleasurability, and that the economic factor enforces mainly positive attitude to EST. Important theoretical and practical implications of these findings are discussed.
