This study attempted to derive the sub-factors for the perception of cosmetology education affecting satisfaction of students with the cosmetology education and analyze their effects on career choice through a questionnaire survey against a total of a total of 120 people who had taken the cyber university cosmology lecture previously. For cosmetology education perception factors, four predictive variables (educational environment, operating system, curriculum and lecture management) and one variable regarding educational satisfaction were derived and used as analysis tools. The purpose of education by academic major was the acquisition of license and theory & practice education in hairdressing and skin care, respectively. Students showed more interest in hairdressing lectures as they had little work experience and in skin care lectures when they had extensive work experience (p<0.01). Correlation was found between the four education perception-related sub-regions and satisfaction with education (p<0.01). In particular, curriculum and lecture management had a positive effect on satisfaction with education with statistical significance. As the perception of lectures increased, students were more satisfied with cosmetology education (p<0.001). In addition, academia-industry cooperation, career analysis, cosmetology lectures and school had influence on career choice. This study found several issues such as difficult curriculum and poor communication, and it appears that it is necessary to develop a better communication plan and new educational lectures by career and stage.

In this study, we developed a learning progression for the structure of the solar system using multi-tier supply form items and validated its appropriateness. To this end, by applying Wilson's (2005) construct modeling approach, we set up 'solar system components,' 'size and distance pattern of solar system planets,' and 'solar system modeling' as the progress variables of the learning progression and constructed multi-tier supply form items for each of these variables. The items were applied to 150 fifth graders before and after the classes that dealt with the 'solar system and star' unit. To describe the results of the assessment, the students' responses to each item were categorized into five levels. By analyzing the Wright map that was created by applying the partial credit Rasch model, we validated the appropriateness of the learning progression based on the students' responses. In addition, the validity of the hypothetical pathway that was established in the learning progression was verified by tracking changes in the developmental level of students before and after the classes. The results of the research are as follows. The bottom-up research method that used multi-tier supply form items was able to elaborately set the empirical learning progression for the conceptualization of the structure of the solar system that is taught in elementary school. In addition, the validity of the learning progression was high, and the development of students was found to change with the learning progression.

In order to examine the effects of circadian rhythm in subjective alertness on the occurrence of traffic accidents, the authors investigated the occurrence rate of traffic accidents adjusted to traffic volume in Seoul and the relative rate of fatal accidents versus total traffic accidents in Korea at different times of day in 1991. We analyzed these data in relation with the circadian rhythm in subjective alertness. The results were as follows. Both the occurrence rate of traffic accidents adjusted to traffic volume and the relative rate of fatal accidents versus total traffic accidents were the highest at 3-4 a.m., known as the time period of the lowest subjective alertness. They were negatively correlated with subjective alertness (p<0.05, p<0.001). In conclusion, it is suggested that the circadian rhythm of subjective alertness should have a significant effect on the occurrence of traffic accidents despite many confounding factors such as driving environments.

This study conducted both a content analysis and Q-methods analysis in order to find media coverage and recognition type of users about ubiquitous environment in digital online age. The perception type of this study were divided into four types in all through Q-methodology. Above all, this study investigated three research problems. First, how is the type of the perception divided into the subjectivity by recognition-characteristic on ubiquitous environment in Korea? Second, what is a trait of character in these same or different types? Third, how did news media cover ubiquitous phenomena overall? Fourth, is there any difference between media coverage and audiences' perception about ubiquitous phenomena? The results show that audiences seem to generally follow the frames that mass media provide. In addition, however, the audiences tend to recognize ubiquitous environment based upon their own schema as following four types: 1. Positive Universality Leading Type, 2. Uncertain Prudence Preference Type, 3. Future Cultural Enjoyment Type, 4. Negative Effect View Type. This study suggests that every efforts such as technology and policies that can improve the quality of ubiquitous environment in Korea should be accompanied.

Students experience a variety of achievement-related emotions during the process of learning the science curriculum. The purpose of this study is to develop an achievement emotions questionnaire for Korean middle school science curriculum to measure the achievement emotions that middle school students experience during study of this curriculum, and verified its validity. The Achievement Emotions Questionnaire-Korean Middle School Science is based on the English version of the Achievement Emotions Questionnaire, developed with reference to Korean middle school science curriculum and the characteristics of science study, from the perspective of the control-value theory of achievement. It has 232 questions, configured to measure nine achievement emotions across three types of academic settings. The questionnaire results can be treated with a high degree of confidence according to the result of our validation, which also verified that the achievement emotions of these students are configured with four internal criteria (learning strategy, achievement motivation and course grade), as suggested by the control-value theory; this in turn verifies that the nine achievement emotions are sufficiently distinctive across study situations. Last, it was verified that the questionnaire has sufficient external validity based on a comprehensive examination of the relation between science achievement emotions and the four criterion variables for each student. This suggests that through the development and implementation of this quantitative questionnaire, basic ground was provided to understand the achievement emotions experienced by middle school students learning the science curriculum.

Despite the importance of the program development activities and the necessity of the systematical investigation on the features of the program development activities in the social service agencies, it has been observed that recent social work studies have ignored an important study area of program development, including the activities of collecting data in the process of program development in social service agencies. Therefore, this study was undertaken to investigate salient features of the activities of collecting data for program development in the social welfare centers in Korea. A questionnaire was constructed with three parts, including a dependent variable and 6 independent variables, and 201 questionnaires were collected from 353 agencies during two months. As the result of the descriptive analyses, the five noticeable features were found, (1) the activities of collecting data for program development in the agencies are very active; (2) staff in his/her twenties are in charge of program development; (3) diverse data are collected in the process of program development (4) hard data are more collected than soft data in the process of program development; (5) the respondents are more despondent on knowledge learned from individual studies than knowledge learned from academic institutes. Multiple regressions were applied to analyze the relationship between independent variables and three kind of dependent variables - total feature of data collecting, collecting hard data, collecting soft data. The result showed that the total feature of data collecting was critically influenced by social workers' autonomy, openness, and knowledge learned from academic institutes, and workload. The activities of collecting hard data was influenced by the above variables, except social workers' workload, The activities of collecting soft data were influenced by the social workers' autonomy, openness, and knowledge learned from academic institutes, and workload. Major findings were discussed and several suggestions were made for future research and improvement of the program development in social welfare centers.
