Our gorvernment announced an educational reformation bill to establish the institutional foundation of educational system on May 31, in 1995. To secure the open education which is to foster students' creativity, individualization and personalization, it was requested that the past teacher-centered system should be changed to learner-centered system. To gurantee such a change, however, there are many conditions that has to be satisfied first. I think that the most important thing for the new system is a close interaction between teachers and students. To accomplish a successful interaction, the teachers' understanding and attitude toward their students must change at first. The purpose of this study is to examine what kind of understanding and attitude the teachers need, and what kind of roles teachers must take charge of. At the same time, I suggest that we need to establish a Teacher Center to give teachers a seperate place to learn new theories, and to exchange among themselves the informations they got from the actual field experience.

Fifth-generation (5G) wireless communication supports low latency of up to 1 ms or less, 20 Gbps of data rate, and more than 1 million connections. With these technical advantages, machines and equipment can be precisely adjusted, allowing 5G to be applied to industrial applications. To expand the industrial application of 5G wireless communications, major countries have introduced dedicated 5G, allowing specific companies to build and use 5G directly. Germany, UK, and Japan allocate 100 MHz, 416 MHz, and 1,200 MHz, respectively, of bandwidth dedicated to 5G. Companies with local licenses from the government are expected to accelerate the application of 5G at a low cost and low-frequency range. Therefore, Korea should introduce private 5G to foster 5G-related industrial ecosystems and successfully implement the fourth industrial revolution.

Social media holds the potential to facilitate vertical political communication by giving citizens the opportunity to interact directly with their representatives. However, skeptics claim that even when politicians use "interactive media," they avoid direct engagement with constituents, using technology to present a façade of interactivity instead of a genuine dialogue. This study explores how elected officials in three regions of the world are using Twitter to interact with the public. Using the Twitter activity of 15 officials over a period of six months, we show that in addition to the structural features of Twitter that are designed to promote interaction, officials rely on language to foster or to avoid engagement. We also provide evidence that the existence of interactive features does not guarantee interactivity.

North Korea sharing a border with China has developed economic relations with China for a long time. During the cold war(from 1950s to late 1980s), political, military and economic ties between the two countries have become stronger because they had maintained the same political and economic system. However their economic relations have significantly changed after China has adopted market economies since the late 1970s. In particular, trade volume has been shrinked significantly since the late 1990s when China began to ask hard currency payments in their commercial transactions. This paper aims to investigate the conditions and prospects of trade and logistics relations between North Korea and China including the problems existed and then make some suggestions to foster their trade relations. In conclusion in order to develop its trade relations with China, it is suggested that North Korea should make significant changes in its economic and logistics system including infrastructure, institutional schemes, social and trade practices ect. because most problems in bilateral trade have been incurred from North Korea.

The purpose of this study is to suggest a social environment to active communities in apartment housing, on the basis of the residents' different social environments of two apartment complexes having their own respective community spaces. A questionnaire was responded by 434 housewives residing in the two apartment complexes which have their own respective space usage and programs in the community spaces larger than is legally specified. The questionnaire comprised items such as neighborhood consciousness, social intercourse, needs of community program diversity. The frequency analysis, the t-test, ANOVA, chi-square analysis were used for the comparison of characteristics of the two apartment complexes. The results of the social environment are as follows. The neighborhood consciousness, social intercourse of residents, and their attitude for participation in the common activities differed according to the residents' socio-demographic characteristics (age, education, number of family, average household income), complex distinctions (presence of clubs, community spaces, and community programs), and the attitude of constructors to foster it. Residents' participation rate and their participation intention showed positive correlation.

The ballistic capability of an alumina-rich oxide armor ceramic against a shaped jet was characterized as a function of penetration depth in a layered target structure. The penetration resistance of the ceramic, based upon the determination of penetration velocity, was not equally realized throughout the depth of penetration. It was abnormally low at an early stage of penetration, followed by a sudden increase to reach ~16GPa thereafter. There was no apparent change in such a profile with respect to the lateral size of the specimen. Based upon 2-D flash x-ray radiography and 3-D Hull code simulation, the feasibility of forming a pressure-induced predamnaged zone in front of the jet tip was speculated to foster an increased penetration velocity in the initial stage penetration, resulting in the diminished penetration resistance. The disappearance of such a predamaged zone with penetration was interpreted to restore the resistance of the ceramic in the later penetration stage.

This paper explores the causal relationship between acceptance attitudes and expected effects of smart work. With the rapid development of smart technologies, lots of organizations try to innovate in the conventional working styles for maximizing organizational effectiveness and efficiency. Although many organizations wish to foster smart working environment, they don't have confidence in detailed action plans and effects from it. Therefore, this study that explores the causal relationship between acceptance attitudes and effects may have crucial meaning to organizations pursuing smart work. In this research empirically conducted by questionnaire survey, the acceptance attitudes as predictors and the expected effects of smart work as influenced variables were used. This research analyzed 118 collected data and multiple regression analysis. As a result of analysis, teleworking shows the positive relations to all of dependent variables. And others have a positive or negative influence on effects of smart work. Results of this study may give implications to organizations that want to implement smart work environment.

Cyberloafing is as counterproductive behavior because it is the act of using internet for personal purposes which can affect employees' productivity, especially when done excessively (more than 4 hours a week). The objective of this study was to analyze whether gender and education level had significant effect on cyberloafing among generations in the workplace. From 267 respondents, gender was not found to have impact on cyberloafing because female and male respondents had the same frequency of low level cyberloafing. However, female had higher excessive cyberloafing than male. Gen Y had significant impact on the relationship between education and cyberloafing but Gen Y with diploma degree was revealed to have excessive cyberloafing. Furthermore, Gen X had started combining professional and personal lives throughout their daily lives. Hence, organizations should foster a culture of hard work by giving challenging job with clear target and worthy incentive but still implementing internet usage policy.
