Smart classrooms have been set up nationwide to utilize smart devices for teaching and learning in the knowledge- based society, As this trend might quickly spread, we have investigated the utilization levels, and issues around the facilities from the experienced teachers. In order to study the impact of easy access to smart devices, the teacher sampling groups were divided into two: one teacher group responsible for smart classrooms and the other group teaching in ordinary classrooms. Survey questions dealt with teacher needs analyses, their expectation of their students' attitude changes, their satisfaction and utilization levels of smart devices currently built in classrooms. The results showed us that teachers have vague expectation about the smart devices and want more highly applicable devices for instruction, improvement of their compatibility with other multimedia devices or applications as well as to improve the resolution of electronic boards. and basic functions of information search and videos that they use everyday.

Objectives: The purpose of the study was to develop dietary change program items that could be used to improve dietary life of the elderly and investigate their validity. Methods: The survey was were analyzed by SPSS program (Ver. 21) and descriptive statistics was performed; a t-test, ${\chi}^2$ test, One-way ANOVA and Friedman test were used to determine the priority. Results: Programs for feeding senior citizens that need to be newly established are largely divided into two fields, namely, application of welfare facilities and application of home care, classified into large, medium and sub-classes. The large class was divided into nutrition management, sanitary control, and other health management. The medium class of nutrition management was divided into nutrition education, nutrition intervention, and menu management and supply. The sub-class was composed of division into application of welfare facilities for the elderly and application of home care for the same age group. Responses showed high rate saying that all the categorized items were necessary and valid. With respect to expectation effect on a community program for old people feeding, 'yes' was 65 people (55.6%) showing very high expectation toward the question whether a community program for old people feeding are newly set up. Conclusions: It is believed that nutrition for the aged will be improved and it will be a help not only to a small facilities without obligation of employing a dietician but also to the aged at home if a community program for old people feeding are newly established.

In the past few years, data leakage of information assets has become prominent issue. According to the NIS in South Korea, they found 375 cases of data leakage from 2003 to 2013, especially 49 of cases have been uncovered in 2013 alone. These criminals are increasing as time passes. Thus, it constitutes a reason for establishment, operation and certification of ISMS, even for private enterprises. The purpose of this study is to examine the factors influencing the certification intention of ISMS using EFA (Exploratory Factor Analysis) and regression analysis. We identified expectation factors for certification of ISMS from 13 elements using EFA (Strengthening practical ability & economic effect factor and Improvement of security level & handling incident factor). Next, we examined that the certification intention of ISMS using regression analysis. As a result of regression analysis, Strengthening practical ability & economic effect factor is not significant for the certification intention of ISMS (p<.05). Also, Improvement of security level & handling incident factor have a significant and positive effect on the certification intention of ISMS (p<.05).

In recent years, although far behind, the "e-Trade (B to G)" is propelled vigorously in Japan. But the diffusion of the "e-Trade" among companies (B to B) represented by bolero.net does not meet expectation. This paper carried out the questionnaire survey to the enterprises, which adopt bolero.net and examined why the diffusion is stagnated to the measures for its future spread. As a result, the top 3 adoption factors are: (1) Transaction climate, (2) Top management support, and (3) Operational improvement. In other words, it depends that top management has the will, which adopts e-trade positively among the reliable business partners and the operational performances can improve efficiently by carrying e-trade. We would like to clarify what will be crucial to spur the diffusion in the future. Based on the findings from the result, the concrete key points to promote the spread are to be indicated as follows: (1) Improve the scores of "Cost" and "Competitive pressure" (2) Improve the institutional factor.
