I studied a group management model of virtual class for distance education system on the information superhighway. There are many objects and actions that need to be managed and controlled in virtual classes of a distance education model. Educators should be able to manage students' learning group and immediately be aware of who is attending and who is quitting the learning group in a virtual class. Also, students and educators in virtual classes can communicate and discuss various topics. I proposed a group management model for distance education on a network, and studied management algorithm and MIB (Management Information Base), which are required to manage virtual classes in distance education systems.

In this paper proposed automated attack reaction tool based on IPv6. Currently, much researches are performing focused on application program and standardization for IPv6. But, It is not enough for future IPv6 security. The proposed method detect attacks on IPv6 and conventional IPv4, therefore it is possible to protect personal information using automated reaction method. Usually, IDS just perform detection, therefore damages may be repeated. However, this paper considered the problems described above, and suggested solution for this problems. The proposed algorithm suggested in this paper is simulated on IPv6 network based on Linux. As a simulation result, it is proved that proposed algorithm can detect attacks efficiently.

This paper examines a disadvantage of low-frequency magnetic shielding measurement based on MIL-STD-188-125-1. A rectangular loop antenna is proposed as an improvement over conventional circular loop antennas for measuring magnetic shielding. Simulation and experiment are used to demonstrate that the proposed rectangular loop outperforms the circular loop for a more reliable shielding measurement at low frequency range.

This paper examines Myanmar's garment industry comparative's competitiveness by selecting Korea and Japan-Myanmar's main target exporting countries for their garment industry-and China and Thailand, the neighboring countries it has continued to have business relationships with since the economic sanctions in selecting the target countries, this study presents a competitive outlook at the Myanmar garment industry's potential for the future by analyzing trade intensity per main garment product. Therefore, Korea should recognize the advantages of Myanmar, compared to other countries with similar competitiveness in the textile industry, and should develop Myanmar textile industry into a future-oriented garment industry through measures such as labor force training, scaling up both industrial relations and safety facilities, and establishing sound labor-management relations.

Korean clients show a tendency to hide the real causes of problem. Therefore the 'grasping the real cause of a problem' is regarded as the first characteristic in Reality Dynamic Counseling. Many counselors stress over how express empathy with a client rather than understanding a problem. However the attitude change wouldn't be attained without grasping the real cause of a problem. The researcher tries to demonstrate how this characteristic is at play in counseling process. The researcher illustrates this process by 'narrative method' as one of qualitative research methods. The client who had received counseling for stress disorder and insomnia took a turn for the better as soon as getting at the truth of his problem.

This qualitative study is designated to explore the reality of social welfare related to the co-occurence of domestic violence and child maltreatment in Korea. "Alone and Together" is elicited as the main theme from the analysis of social workers' experiences with the co-occurence problem in the two fields of domestic violence and child maltreatment. Despite the fact that the social workers are aware of the co-occurence problem embedded in their field cases, they don't assess and intervene with the problem on set purpose. Each field has dealt with the problem according to the field priority for either women or children separately. However, the social workers in the both fields desire alternatives effective for their cooperation and linkage to each other when confronted with the intersection of interdependent needs and problem-solving for the woman and the child. The development of multi-level research, assessment tools, and compulsory education courses for practitioners related to the co-occurence problem is suggested.

Korea is recognized as the most advanced nation in regards to capabilities or environments of informatization throughout the world. Nevertheless, Korea brings on itself such stigmas as a nation vulnerable to information security. Now the globe ushered in an era requiring political balances. Yet, issues of legislative supports or system adjustments for information security policies are always pushed back on the priority list. There is a need to face problems at the center of changes departing from such frames. In order to establish a proper system for information security policies, the most urgent issues are reviews of concepts and reorganizations of systems, and then to legislate information security polities by being harmonious with public opinions. This paper is to remind what measures are needed to improve the system of priority policies depending on public backgrounds and why such measures are needed. Furthermore, the paper suggests a new legislation, 'Information Security Policy Act' as one of the specific measures.

Gold stock could include the U.K. in the European economy by the alternative plan of the problems that it was occurred while nationalizing industry and a company for economic recovery and national profit after the World War Ⅱ and it was wide and came to open in the country of European most. However, the negation was sentenced to it for the reason of the gold stock which the U.K. adopted in European many countries infringing "freedom of the capital movement" at a European court of law. However, I consider gold stock positively to protect it from hostile M&A of the company of the national strategy from the Middle East and an Asian national rich fund recently in France and Germany. If our country looks straight at reality, Urstatut or the agreement of the majority stockholder have a very strict matter assuming the protection of the existing shareholder and must be able to gain the favor if you look by the flow of such world economy.

According to increase of preference to the large display device, demand of a three-tube projection TV increase in the display market. But luminance per unit area of a 3-tube projection TV is less bright than that of original one -tube TV The color gamut of phosphor used in the projection TV is different to standard gamut of phosphor in NTSC. In this paper, we analyze the relationship between coordinates of RGB phosphor and RGB beam currents according to the color temperature in projection HDTV. We also proposed the range of reference white which maximize the luminance that viewer feel based on both Helmholtz-Kohlrausch effect which is visual property and degradation of image according to the change of beam profile by current-ratio.

This study surveys the fabric surface properties such as mean value of the friction coefficient(MIU), mean deviation of the friction coefficient(MMD) and mean deviation of surface roughness(SMD) due to warp and weft tension differences using KES-FB system. For this purpose, fabric is designed as 5 harness Satin weave using 75d/36f warp and 100d/192f weft polyester filaments, and is woven by OmegaR rapier loom by Textec Co.Ltd and Picanol-GTXR rapier loom by Picanol Co.Ltd respectively. These grey fabrics are processed on the same dyeing and finishing processes. The fabric surface properties according to the weaving looms are analysed with warp and weft weaving tensions. And also surveyed the difference of fabric surface properties according to the fabric positions such as center and each edge of fabrics for the sensitive garment.
