This study aims to propose educational information services for social science teachers by analyzing their information seeking behaviors. The author carried out in-depth interviews with thirteen social science teachers in Daejeon and analyzed them using an information seeking behavior model of Leckie, Pettigrew and Sylvain. The study results showed that information needs of social science teachers arise from extrinsic and intrinsic motivations according to their work roles and tasks. Also, the characteristics of information needs such as repeatability, predictability, urgency, and complexity appear to influence information seeking behaviors. The participants used various information sources including web, book, and interpersonal sources. Moreover, the study observed some factors that may influence perception toward information sources such as trustworthiness, information quality, packaging, prior success experience. Finally, the perception change and use frequency of information sources were also identified. Based on these findings, the author proposed information services for social science teachers including integrated information provision services, information literacy programs, networking services and readers advisory services.

This study was conducted to provide basic information on the sexual mature and reproductive biology of Trichiurus lepturus. During the oogenesis, size of oocyte and nucleus showed the increase tendency but size ratio of nucleolus to nucleus was decreased. In the result of H-E stain, the stainability of the cytoplasm was changed from basophilic to eosinophilic. The egg diameter of initial vitellogenic oocyte was about 63.2 (±12.7) ㎛. In the cytoplasmic cortex, eosinophilic yolk nucleus was observed. The size of mature oocyte was 216.6 (±24.7) ㎛ and GVBD (germinal vesicle breakdown) was observed. The size of ripe oocyte was 317.9 (±80.9) ㎛ and the thickness of zona radiata was 4.2 (±1.7) ㎛. The oocyte developmental type is considered to belong to the group synchronous type. The accumulation of yolk in the oocyte, like most teleost, is thought to be of two types: exogenous and endogenous accumulation.

The present study examines the role of subjectively perceived factors of the attitude toward web shopping in forming an intention to use a web shopping intention. An integrative research model is presented and tested empirically. It includes the following three aspects of belief in Davis' TAM: perceived usefulness, perceived ease of use, perceived enjoyment. Specially, internet self-efficacy, or the belief in one's capabilities to organize and execute courses of Internet actions required to produce given attainments, is a potentially important factor in efforts to gain more favorable attitude toward web shopping close the digital divide that separates experienced Internet users from novices. Prior research on Internet self-efficacy has been limited to examining specific task performance and narrow behavioral domains rather than overall attainments in relation to general Internet use, and has not yielded evidence of reliability and construct validity. Survey data were collected to develop a reliable operational measure of Internet self-efficacy and to examine its construct validity. Also, much previous research has established that perceived ease of use is an important factor influencing user acceptance and usage behavior of information technologies. However, very little research has been conducted to understand how that perception forms and changes over time. The present study examines that higher internet self-efficacy is more getting favorable web shopping attitude, and web shopping intention as more as usefulness, enjoyment through the internet.

Korea's economic development started from early 1960s over war devastation. Korean government drove promoting export with its all efforts. In 2011, Korea joined the "USD 1 trillion trade club" as the 9th nation in the world. It is true that the growth of Korean exports has greatly contributed to the development of Korean economy, and that workers in the export promoting organizations also contributed to such a tremendous performance. Still, there are a number of SMEs waiting for more support from the export promoting organizations. This paper tried to identify the determinants of organizational performances of export promoting organization workers with particular focus on their public service motivation and self-esteem. Our findings are as follows; Workers' public service motivation and self-esteem are strongly related to their organizational commitment, job satisfaction, organizational performances. In addition, the workers show a different level of intrinsic and extrinsic satisfaction when it comes to public service and customer satisfaction. This reflects the employees of export promoting organizations have more focused on the value and accomplishment of their performances in workplace. Women and younger workers within the organizations tend to have weaker organizational commitment. In conclusion, we recommend that it is important to increase the women's organizational commitment and develop more inspirational personnel programs to younger workers within the organizations in order to support Korea's promising SMEs in a more practical manner.

The purpose of this study was to identify work-family balance values(work-family centrality, marriage value, child-care value, work value etc) in Korea, Japan and U. K.. Moreover, This article investigated the attitudinal generational gap in each countries. Participants were 311 Korean, 324 Japanese and 322 English married working women, who were in the thirties fifties. The major findings of this study were as follows. Compared to Japan and U. K., Korean married working women were more work-centered and likely to seek for extrinsic work value as well as intrinsic work value. While they were highly thought that a woman should work despite of her marriage, it was also strongly concerned if their work negatively affected family life, they should be better to quit their job. These results showed that conservative-liberal values were coexisted in Korean participants. Secondly, U. K. participants were more centered on the family-oriented value and thought that women were not necessary to work in work-family conflict, in comparison to Korean and Japanese. As a result of cluster analysis, they were a lot distributed in 'woman's family care oriented group' which was weigh on woman's role as a family care giver as well as 'family value oriented group'. Thirdly, Japan participants not only were less family-centered but also less work-centered. In the similar vein, they were less motivated and oriented to all of intrinsic and extrinsic work values compared with participants in Koran and U. K. On the other hand, Japanese participants, in sharp contrast to Korean, had a liberal viewpoint in work-family related values, such as woman's work, career break caused by work-family conflict, and family values. We were trying to interpret these results in consideration of socio-economic-politic as well as psychological aspects.

The major goals of this study are to find the factors that enhance self-directed math learning in college math classes and to provide the students with the opportunities to check and develop their self-directed math learning attitude. For these research goals, we prepared the questionnaires that asked about their learning motivations, basic learning ability, self-discipline strategies, and self-directed learning strategies. Another purpose of the questionnaires was to give them the chances to check and improve their attitude toward those learning strategies, motivation and ability. From the research results, we find that the important factors for self-directed learning are internal & external motivations, concentration ability, and the goal-setting and plan-making abilities. In addition, concentration ability, good habit, stress-control, recognition of math value, and self-directing ability are found to be necessary for the desirable learning environment. On the other hand, we find that the ability to perform note-taking, class preparation and review, time-control, and test-control is required for the selection and practice of self-fitting learning strategies. Finally, we provided our own self-directed math learning model. Our model, containing the necessary factors for self-directed math learning, is the revised and modified one of Knowles(1975)'s 5 stage self-directed learning model that comprises diagnosis of learning desire, setting learning goals, grasping human&material resources, selection and practice of proper learning strategies, and evaluation of learning results.
