The question how man can perceive the direction of a sound is one of the traditional psychoacoustical problems. Rayleigh already began to investigate this subject in 1870s and kept on interesting himself intermittently throughout his research career. Rayleigh was only concerned with this subject among those of perception of sound and focused more interest on it than any other acoustical problems. At first he insisted on the perception of the direction of a sound by the difference of intensity of a sound in two ears. but was phased in accepting that by the difference of phase of a sound there. Thus he arrived at the modern view that the perception of the sound direction is caused by the difference of intensity in high frequencies and the difference of phase in low frequencies. Rayleigh presented his ability as an excellent experimenter by employing very cautious and ingenious experimental settings and acquired persuasive results by linking the consequences of his mathematical theorization with his experiments.
The purpose of this study is Big Five personality factors of personality type on career behavior, that is, entry to the unsafe first job in Korean university students.

Among 350 questionnaires, 342 copies were used for a final analysis. In order to analyze the survey data, statistical package program SPSS/WIN 18.0 was utilized and statistical techniques such as basic statistical analysis, factor analysis, Cronbach's alpha, correlation analysis, and multiple regression analysis were used. The results obtained in this study can be summarized as follows. The extraversion personality and agreeableness personality of college students has a significant effect on the entry to the unsafe first job in the positive direction. On the other hand, the neurotic personality and openness to experience has a significant effect on the entry to the unsafe first job in the negative direction.

The purpose of this research is to grasp the present state of marine lifelong education and to provide direction for maritime industry. In this research, we first saw our country present ocean industry and the ocean lifelong education concept and definition besides formal school education to secure ocean human capital. Second, we researched about the ocean lifelong education that has been progressing by the organization, and by this, we inferred what to improve from our country ocean lifelong education. As a result, the improvement point for present ocean lifelong education of our country was first, the reflect of variety of marine related information in our country lifelong education is low, second, the learners were mostly children and teenagers, third, most of the were event education. Forth, it is good that there are a lot of experimenting programs, but most of them were experiment of ocean leisure sports and visiting the facilities, and because these are one-time thing so it was hard to secure marine citizenship or help them set their career in marine. Fifth, all facilities had similar contents for the experimenting program, and sixth, education period was concentrated on May and November.
In this study, we analyzed career paths and college life plans of department of chemistry education students in teacher's college examined by their roadmaps. We let students make their roadmaps and analyzed them using the PASW 18 program. There were significant differences on gender in their career paths, learning English, traveling and volunteer activity. Female students for passing the MEET(Medical Education Eligibility Test) or DEET(Dental Education Eligibility Test) were more interested in learning English and traveling than male students. In addition, female students were more interested in volunteer activity. And the lower year students, the more interested in medical paths, learning English, traveling, getting good grades, exchange student program and scholarship. On the other hand the higher year students, the more interested in group study or E-learning. Then significant differences were in learning English, traveling and getting good grades by students's career paths. Students who wish to pass the MEET or DEET were more interested in learning English and getting good grades. Those two factors were essential in passing the MEET or DEET. Students who did not specified their career paths had more traveling plans than other students for setting their directions of careers. These results show that freshman and female students don't recognize the identity of teacher's college correctly. Because of reduction in the number of teacher recruitment according to decrease of students by birth rate drop, students in teacher's college are expected to continue like this trend that students look for other paths. Therefore, it is required career counseling and guidance for students who give priority practical path choices and college life plans over original characteristics of teacher's college. And it should be reconsidered the direction of chemistry education prepared the identity of teacher's college reflected in this actuality.

The portfolio can be used as a methodology supporting the learning of constructivism. Recently, the use of portfolios has been increased gradually in the education field, but a study on the current state analysis and design direction of portfolios leaves much to be desired. In this paper, we analyze statistical data on the portfolio application of teachers in domestic elementary, middle, and high school. We also propose a design direction of e-portfolio needed in the society of knowledge information based on this analysis. The results of research show that the following problems will be improved: understanding portfolio, analyzing the current state according to the types of portfolio application, designing a distinguished system according to the level of school, expanding education of teachers with high career, and developing a guide helper. The design of total system that combines the learning and evaluation is needed to improve a problem that spends lots of time to make portfolio, and operates temporally and formally achievement evaluation. In addition, the design of e-portfolio supporting efficiently interaction and self-directed teaming is required.
