The latest development of the Korean drama production industry has been accompanied by the steep rise in the number of players and the contraction of the advertizing market, which have combined to intensify the competition severely. Then, China happened. Entertainment agencies' logical strategic choice to maximize production revenue potential was to secure A-list actors who can sell, pushing up their prices, that process has continued to even compromise the health of the production industry as well as the agencies' financial integrity. The drama production industry, including entertainment agencies, should shift the strategic focus from simple production revenue generation to profit maximization through diversifying revenue sources like securing IP rights.

This paper analyzes herd behavior observed in the loan market from 2001 to 2014 using a panel data on commercial banks including state-owned banks, domestic private banks, foreign banks, and Islamic banks. The paper finds evidence that herd behaviors of domestic private and foreign banks have been pronounced and long-lasting around the 2008 global financial crisis when state-owned banks did not show such a behavior. This result shows that since private banks tend to be keen on maximizing profits and avoid financial risks exposed by lending during a financial crisis, their lending decisions are not independent but dependent on whether other banks increase loans or not. On the other hand, Islamic banks do not show herd behavior during the financial crisis. This finding is consistent with earlier studies that Islamic banks have different characteristics, such as profit and operation mechanisms, from other private banks. Another interesting finding is that when it comes to rural loans, all the banks' herd behavior is short-lived and the herding indexes are quite volatile. This finding is attributable to distinct features of rural loans. Usually maturities of rural loans are shorter than city loans and related to the cycle of farming. Agricultural production is heavily dependent on unpredicted factors, such as floods and droughts, not previous year's production. Lastly, the paper finds a herding across bank type that state-owned, foreign, and Islamic banks follow domestic private banks'lending decisions.

섬유산업은 fiber로부터 시작하여 yarn, fabric을 거쳐서 최종 섬유제품인 clothing을 생산 하는 복잡하고 긴 stream을 가지고 있으며, 최종상품으로 갈수록 부가가치가 높아지는 특징을 가지고 있다. 특히 최근에는 다양한 구조, 디자인과 함께 감성과 개성을 중요시하는 의생활 패턴의 변화에 기인하여, 의복의 형태가 다양화되고 기능에 따르는 구조의 변화와 소재의 다변화를 통해, 어패럴 산업의 개념과 기술적 변화가 크게 요구되고 있다.(중략)

정보통신산업은 대규모 설비투자, 자연독점성, 망의 부성이 지배적으로 나타나고, 공급 및 수요의 잠김효과와 쏠림현상이 크며 기술의 혁신정도가 매우 크다는 규제의 대상이 되어 오고 있다. 그러나 최근 정보통신업은 다각적인 측면에서 급변하고 있다. 이러한 급격한 재반 변화는 규제자체에 대한 재고의 여지가 있고, 경쟁상황평가에 대한 근본적 인식의 전환이 요구되는 것이다. 본 고는 규제의 시발점이라고 할 수 있는 시장의 정의, 관련시장의 경쟁상황 평가와 시장지배적사업자 선정에 이어 규제옵션 및 규제수준을 설정하는 합리적 방향에 대해서 서술하고 있다.

본 논문은 3레벨 정류기와 직렬 입력, 병렬 출력 LLC 컨버터가 연결된 전원 장치의 DC-Link 전압 불평형 제어에 관해 분석한다. 일반적으로 380Vac 입력을 가지는 3레벨 부스트 기반 정류기는 출력 전압을 700Vdc 이상으로 제어한다. 또한, 3레벨 컨버터는 두 개의 직렬 출력 커패시터를 가지며, 불균형 해소를 위한 제어 또는 물리적 불평형 해소 소자가 요구된다. 스위칭 신호를 공유하는 두 개의 LLC 컨버터가 연결된 시스템에 DC-Link 불평형 전압 제어가 적용되면 전력의 쏠림 현상이 발생한다. 본 논문은 제시된 시스템에서 전력의 쏠림 현상에 대해 그 원인을 분석하고 실험으로 검증한다.

전기통신사업법상 이동전화사업자의 단말기보조금 지급금지 그 자체는 경쟁원리에 부합하지 않는다. 단말기 보조금의 금지를 정당화하는 유일한 근거는 그것이 갖는 비대칭적 성격이나, 그로 인하여 유효경쟁이 촉진될지는 확실치 않다. 이동전화시장에서 사업자 전환에는 요금이나 통화품질보다 이용자의 전환비용이 매우 큰 영향을 미치며, 따라서 전환비용을 낮추는 것에 초점을 맞출 필요가 있다. 그렇다면 번호이동성을 통하여 충분히 제거되지 않는 고착효과 및 전환비용을 가능한 해소하기 위해서는 지금과 같이 엄격하고도 일률적인 단말기보조금 금지는 재고할 필요가 있다. 여기서 유의할 것은 경쟁적인 보조금 지급이 후발사업자의 존속을 위태롭게 할 수 있다는 점에서 통신시장에서 어느 정도 유효경쟁체제가 자리잡은 이후에야 보조금 지급을 완전히 허용할 수 있다는 점이다. 다만, 비대칭규제의 취지는 어디까지나 이미 쏠림현상으로 고착화된 독점적 시장구조를 유효경쟁체제로 전화하는 데에 있다는 점에서 볼 때, 어느 시점에서 단말기 보조금을 허용할 것인지는 현재 또는 향후의 시장 상황에 대한 면밀한 분석을 요한다.

This paper aims to develop methodology and indicators to review effective competition in Korean mobile telecommunication market. After examining strengths and weaknesses of other countries' experiences, we proposed several indicators for the assessment of competition. Developed from criteria such as transparency, regulation cost, policy objectives, proposed indicators comprise market structure, behaviour of sellers and consumers, and consumer benefits. These indicators are applied to the Korean mobile market. During the period 2001-2004, 'the competition assessment index' increased steadily, meaning the state of competition was aggravated during this period.

Recently, a new distributed grid scheme, called DS-GRID(distributed S-GRID), has been proposed to manage the location information of moving objects in a spatial network[1]. However, because DS-GRID uses uniform grid cells, it cannot handle skewed data which frequently occur in the real application. To solve this problem, we propose a dynamic distributed grid scheme which splits a grid cell dynamically based on the density of moving objects. In addition, we propose a k-nearest neighbor processing algorithm for the proposed scheme. Finally, it is shown from the performance analysis that our scheme achieves better retrieval and update performance than the DS-GRID when the moving objects are skewed.

The urban-rural consolidated city has emerged in order to promote the balanced development of urban region and rural region. Targeted 11 urban-rural consolidated cities in Gyeonggi Province, this paper investigated the changes of economic space in accordance with the location of industrial activities. The number of establishments has increased in all cities. From the analysis of the changes in the economic space divided into urban regions and rural regions, concentration phenomenon of economic activities in urban regions was strengthened in 9 cities with the exception of Icheon-si and Anseong-si. Concentration of economic activities in urban region was noticeable in Namyangju-si, Pocheon-si, and Yongin-si. 5 types were derived from the classification on the basis of locational changes of economic activities in urban region and rural region. They are 1) urban-rural gap deepen type, 2) urban region growth slowdown type, 3) rural region growth type, 4) urban-rural balanced growth type, and 5) urban region-led growth type. While urban-rural gap of the cities close to highly urbanized city or metropolis has intensified, the growth of urban region was weakened in the cities located away from the metropolis.
