The purpose of this study was to search the obese related dietary factors of young adolescent girls for developing nutrition education program. In the cross-sectional study of 371 young adolescent girls, 25$\%$ were moderately obese, 13.2$\%$ obese, and a total of 39.1 were over moderately obese. The characteristics of obese girls were as follows. First, obese girls consumed more energy than is needed for physical activity. Their average daily energy intakes were not significantly higher and the daily energy expenditures were significantly lower than those of normal girls. Second, obese girls showed higher intakes of protein and fat, and ate more animal foods than normal girls. Fourth, obese girls skipped meals more often, especially breakfast. They ate less rice. For both normal and obese girls, their common dietary problems were low intake of calcium and iron, and high intake of snack foods. The result of this study shows that nutrition education programs for obese adolescent girls should be designed for eating habits, food balance and moderation. future research is to develop the effective nutrition education program for the obese adolescent girls.

Influenza A virus is a single-stranded RNA virus with a genome of negative polarity. Owing to the antigenic diversity and cross concrete shift, an immense number of novel strains have developed astronomically over the years. The present work deals with the codon utilization partialness among five different influenza A viruses isolated from human hosts. All the subtypes showed the homogeneous pattern of nucleotide utilization with a little variation in their utilization frequencies. A lower bias in codon utilization was observed in all the subtypes as reflected by higher magnitudes of an efficacious number of codons. Dinucleotide analysis showed very low CpG utilization and a high predilection of A/T-ending codons. The H5N1 subtype showed noticeable deviation from the rest. Codon pair context analysis showed remarkable depletion of NNC-GNN and NNT-ANN contexts. The findings alluded towards GC-compositional partialness playing a vital role, which is reflected in the consequential positive correlation between the GC contents at different codon positions. Untangling the codon utilization profile would significantly contribute to identifying novel drug targets that will pacify the search for antivirals against this virus.

It is very a time-consuming and error-prone process to obtain the optimal injection condition, which can produce good injection molding products in some operational variation of facilities, from a seed injection condition. This study proposes a new approach to search the optimal injection molding condition using a neural network and a genetic algorithm. To estimate the defect type of unknown injection conditions, this study forces the neural network into learning iteratively from the injection molding conditions collected. Major two parameters of the injection molding condition - injection pressure and velocity are encoded in a binary value to apply to the genetic algorithm. The optimal injection condition is obtained through the selection, cross-over, and mutation process of the genetic algorithm. Finally, this study compares the optimal injection condition searched using the proposed approach. with the other ones obtained by heuristic algorithms and design of experiment technique. The comparison result shows the usability of the approach proposed.

This study is to seek alternatives for regional governance related to transnational labor migration issues in Southeast Asia. This study examined the present situation and trends of labor migration in the region, reviewed involved transnational issues, and identified the current issues of governance to seek alternatives for regional governance. The increase in cross-border labor migration is no doubt a sign of growth and dynamism of the region and greater integration of their economies. But it also poses complex policy and management issues as well as transnational issues over such as unequal economic profits, illegal migration, human rights, and social security issues. In this reality, regional governance is a very important theme and the efforts to manage their migration inherently involve fundamental conflict and tension between related countries and regions. However, politics and governance of transnational migrant workers in Southeast Asia are still pursued at the national level. To resolve these issues, it is urgently required to secure not only collaboration between the parties concerned but also governance at the regional level. Findings of this study are: First, although labor migration has been a relatively long-time transnational issue, the history of addressing the issue at the regional governance is very short and still inceptive. Second, given its size, labor migration in Southeast Asia requires effective regional governance but no breakthrough was possible due to the conflict of interests between origin and destination countries and the conflict of logic between the labor market and the state. Third, the issue of labor migration is an important element for the formation of economic and socio-cultural communities the ASEAN countries have pursued. Fourth, it is urgently needed to seek alternatives for good and effective regional governance as a key to resolving these issues over migrant workers in Southeast Asia.

미디어산업의 규제는 미디어 개별 콘텐츠에 대한 내용규제와 특정 분야의 진입 퇴출에 관한 소유규제로 나눌 수 있다. 본고에서 살펴보고자 하는 소유규제는 여론독과점의 방지와 다양성의 확보를 위한 핵심적인 법적 정책적 수단이다. 세계 각국은 자국의 특수한 미디어 환경을 기반으로 한 규제모델을 가지고 있으며, 한국 또한 환경변화에 조응할 수 있는 정책으로 미디어산업의 활성화와 수용자의 권익을 보호할 수 있는 최대공약수를 도출해야 할 정책적 과제를 안고 있다. 특히 공익성이 여타 어느 산업분야보다 중시되는 현실에서 미디어산업의 규제정책은 공익성에 대한 확고한 정책적 의지가 필요한데, 이를 실현시킬 소유규제 정책의 핵심적 요소가 이종매체 소유에 관한 것이다. 방통융합의 본격화로 미디어 산업의 지형이 변화하는 가운데 주요한 이슈가 되고 있는 이종매체 소유규제는 사업자별 이해관계와 미디어산업에 대한 관점에 따라서 사업자 및 시민단체, 정책당국의 갈등요인이 내재되어 있다. 이러한 상황에서 이종매체 소유규제의 근거논리인 '공익' 개념의 재정립 문제, 소유의 집중과 다양성의 문제에 대한 재개념화 필요성을 모색했다. 신문방송 겸영으로 대표되는 국내 미디어산업의 이종매체 교차소유 문제를 변화하는 산업지형에 비춰 재검토 함에 있어 국내 신문기업이 처한 현실적 조건을 위주로 살펴보았다. 또한, 미디어 융합시대에 촉발된 정책적 딜레마 상황을 이종매체 소유규제를 중심으로 논의한 후 효율적 갈등관리의 필요성을 제기하였다. 끝으로 미디어정책 기관의 독립성과 신뢰회복, 규제모델의 합리화, 이종매체 소유규제 이슈에 대한 각론적 접근, 매체균형발전을 위한 지원정책의 내실화라는 정책적 제언을 제시했다. 거대 미디어그룹의 여론과 산업에 대한 독과점 방지 정책이나 이종매체 소유규제는 해외 각국에서도 정책적 과제로 남아있음도 살펴보았다. 이종매체의 겸영 이슈를 포함한 미디어산업에서의 딜레마 상황과 이에 대한 이해관계의 조정은 매체환경의 급속한 변화에 부응한 '공익성과 산업성의 조화'라는 바탕 위에서 조속히 마련되어야 할 정책적 과제라 하겠다. 한국에서도 매체환경 변화에 부응하는 소유규제의 완화는 고려할 수 있으나, 신문과 방송 겸영을 포함한 이종매체 겸영은 신중한 접근이 필요하다. 이종매체 교차소유 완화는 여론독과점의 우려를 불식시킬 정도의 풍부한 저널리즘적 토양이 전제가 되어야 함을 역설적으로 확인할 수 있다.
