NCW is a new operational concept for modern warfare to improve the ability to conduct combat by connecting command and control system via network. To realize NCW integrating information sharing system between multiple platforms, CDL is considered as a key component for high-speed transmission of ISR data. Accordingly, further studies to enhance the performance of CDL are being performed around the world, and our government has also developed self-reliant CDL, MPI-CDL. However, the maximum data rate and networking performance of current CDL still fall short of the objective to enable multiple systems to share the large ISR data. Therefore, in this paper, we analyze the development flow and international technical trends of CDL, and present an approach for enhancing data rate and networking capacity of the next generation CDL.

This paper investigates spatio-temporal changes in the international system of linkages among multinational corporate domestic decision-making centers and their overseas subsidiary centers for the period 1974-1991. During this period advances in information technologies and an ever increasing interdependent world economy have permitted the globalization of resource transfers, production techniques, service provision and financial transactions. Based on a network theory of internationalization, the study idenifies the dispersion of multinational control centers and the diversification of their linkage patterns. These tendencies are led by small and medium sized quaternary places as well as the rapid growth of service industries. Corporate headquarters cease to be tied together to big corporate and governmental centers but will disperse over time at global, national and regional level. Using information statistics, this paper confirms the dispersion patterns of capital flows and diversification of multinational control linkages. With an increasing trend toward a multicentric world system and the associated diecline of the global hegemony of a small number of largest cities, multinational control linkages should continue to disperse.

Objectives : This study was done to develop Korean form of Reynolds' SIQ-JR(Suicidal Ideational Questionnaire-Junior). Through this study we evaluated reliability and validity of Korean form SIQ-JR. Methods : Subjects were 1,160 middle and high school students and 114 adolescent psychiatric patients. SIQ-JR and 8 self-reporting scales highly related with suicidal ideation and suicide behaviors were applied to them. Results : In reliability aspect of Korean form of SIQ-JR, internal consistency, test-retest reliability and item-total correlation were statistically significant results. In factor analysis, concerning about other person was extracted as a indepenedent factor. This results reflect our cultural characteristics. There were statistical differences of SIQ-JR scores in groups by sex and age. Clinical group showed significantly(P<0.01) higher scores than general population. Among the 8 suicidal relating scales, depression(r=0.42), aggression(r=0.36), trait anxiety(r=0.35), and anger-in(r=0.31) were highly related with suicidal ideation but impulsivity and hopelessness were not significantly related with suicidal ideation. Conclusion : Korean form of SIQ-JR was useful instrument in reliability and validity. We hope that this instrument widely used in school mental health, community psychiatry and clinical setting for screening tool.

This study reveals online education of entrepreneurship based on PBL and flipped learning method has positive effect on personal entrepreneurship, will to be an entrepreneur, and problem-solving skills. First, the results show that entrepreneurship education based on PBL and flipped learning can improve entrepreneurship more than a previous learning method. Second, PBL and flipped learning based online education affects will to be an entrepreneur in positive way. Experimental group who experienced problem solving activity and flipped learning has more will to be entrepreneur than control group who takes previous learning method. Lastly, PBL and flipped learning method based entrepreneurship education also has positive effect on personal problem-solving techniques. This results show that online entrepreneurship education based on PBL and flipped learning has positive impacts on entrepreneurship, will to be an entrepreneur, and improving problem-solving skills significantly.

The results of this meta-analysis showed that, effect size of the nonpharmacologic interventions of total -0.33, occupational therapy - 0.26, multi-sensory stimulation intervention -0.65 was significant beneficial effects to elderly with dementia(p<.05). According to interventions as a major affected the symptoms associated with behavioral problems, mainly aggression, memory-related problem behavior in the home-based program. Also, reminiscence therapy and occupational therapy is generally apathy, multi-sensory stimulation and music therapy was confirmed that there was a major change in behavior anxiety or agitation.

The purpose of this study is to explore the journalist Song Kun-Ho's ideas of Korean Journalism. The journalist Song Kun-Ho was born in 1926 and passed away in 2001. He became a reporter in 1953 when he was a student at department of law of Seoul National University. He has worked for several media and resigned the executive editor at the Dong Ah Ilbo in 1975. At that time, while many reporters of the Dong Ah Ilbo struggled for the freedom of the press, he tried to protect reporters and independence of media. After his resignation of the executive editor, he wrote many columns and several books for Korean nationalism and the democracy of journalism. Instead of working for the authoritarian military regime, he chose a lonely and rough life as an intellectual journalist in action. Finally, he, as a president, established the Hankyoreh daily newspaper which was funded by tens of thousands citizens. He passed away in 2001. His ideas of Korean journalism are nationalism, democracy, and independency. These ideas are very important to restore democratic journalism which has been at risk during the Lee Myung-bak administration.
