This study investigates empirically the export competitiveness of Korea and Japan in America by calculating 4 indexes such as market share index(MSI), export similarity index(ESI), market comparative adventage index(MCAI) and market share expansion ratio(MSER)-export similarity deepening ratio(ESDR). The empirical finding of this analysis shows that Korea is competitive in the labor-intensive products and Japan in the technology-intensive products. This result also meets the general understandings that Japan is superior to Korea in the export competitiveness such as value added of goods, etc. Therefore, in order to strengthen the export competitiveness of Korea in the US market, it's desirable for our firms and government to improve the quality of product ranges by developing technologies focused on the higher value-added products.

This paper empirically analyzes the influence of export insurance on export promotion using panel data for the Korean case during the sample period from 2003 to 2006. We use the Korean export's share in trading partners' imports as a weight for the weighted least square (WLS) estimation to measure the effect of export insurance on the export promotion. Our main finding is that export insurance subsidy seems to enhance the export performance when the Korean export takes greater share in other countries' markets. On the other hand, under weaker monopoly power of the Korean export, export risk and trading partners' GDP growth rate has more influence on the export promotion rather than export insurance subsidy. Our finding implies that policy makers and practitioners should discern the Korean exports' monopoly power differential across trading countries for better performing export insuarnce policy.

Purpose - This study undertakes to examine the automotive trade structure between Korea and Russia to accelerate economic cooperation and pinpoint trade discrepancies to increase trade volume through improved policies, eventually finding ways for trade expansion. Research design, data, and methodology - To analyze trade decision factors for both countries, the Index of trade specialization invented by trade specialization theory, is used. Although specific factors should materialize in the trade decision analysis, realistically, concrete explanations are difficult as many unsolved factors are involved as well as their complexities Results - First, to assess comparative market competitiveness, the Index describes A value/B value, representing the Korean versus the Russia market share and the Korean market share versus the world. Second, the index shows that Korea is taking comparative advantage of its export specialization. Third, the RCA indices show considerable improvement compared to 2000. Conclusions - This research used a quantitative approach to examine trade specialization and examined a comparative advantage index of market share to see how inter-trade relations have changed over the past 10 years.

Customer satisfaction level is usually measured in terms of price, qualify, customization, after-sale-service, product variety etc. Each firm sets up a distinctive production/marketing strategy to gain competitive advantage by Prioritizing the customer satisfaction measures. The market differentiation strategy directly results in supply chain performance such as lead time, inventory, customer fill rate and market share. Product proliferation desirable in customization sense often conflicts the economies of scale effect in production side. This paper focuses the relationship between product variety and market share. Specifically, we investigate how introduction of new product affects the current market share, i.e., formation of customer preference and provide some insight into the optimal range of product variety.

In knowledge-based economy, a nation's knowledge resources are critical factors for its competitiveness with other nations. This study analyze the quantitative and qualitative share of ISI publication of Korea as the level of knowledge resource by using the SCI database. This paper uses RCI(Relative Citation Impact) index for the qualitative analysis. The result shows that Korea's qualitative share of ISI publication measured by citation is relatively small than the quantitative share meaured by number of papers. In research field, natural sciences and medical sciences are relatively weak than engineering and agriculture.

The purpose of this study was to find out adolescents' and their mothers' responses to the minimum standard of age suggested by previous research not to share bedroom among parents and child, children of the opposite sex, or children of the same sex. The data from 310 pairs of junior school students and their mothers were analyzed. The results showed that the percentages of agreements to the suggested ages were not the same. Adolescents were in general more likely flexible to the minimum age than were their mothers. The age standard of the opposite sex children over 10 years old must not share a bedroom was the most agreeable both to child and mother. Both mother and adolescents' children were more likely flexible to the rule that parents should not should not share a bedroom with a child over age 5. However, they were serious about sharing a bedroom between same sex children regardless age. Further research should reveal precisely the age standard represent the high agreement among the family members.

WRR 스케줄링 알고리즘은 계산의 단순성과 저 비용 구현의 장점을 가지고 있어 고속 패킷 스위칭 네트워크에서 널리 쓰이고 있지만 버스티한 트래픽에 대해서는 입력 트래픽을 일정 비율로 스케줄링하기 때문에 효율성이 낮다는 문제점이 있다. 또한, WRR 알고리즘은 ABR 서비스 클래스의 공평성 기준의 하나인 Maximum of MCR or Max-Min share 공평성을 만족시키지 못한다. 따라서 ABR 서비스를 위한 공평성 기준을 만족시키는 스케줄링 알고리즘이 필요하다. 따라서, 본 논문에서는 ABR 서비스를 위한 5가지 공평성 기준들 중 Maximum of MCR or Max-Min share를 만족시키는 스케줄링 알고리즘을 제안한다. 제안된 알고리즘이 공평성 기준을 만족시키고, 네트워크 자원을 각 ABR VC들에게 공평하게 할당해 주는지를 컴퓨터 시뮬레이션을 통하여 WRR 알고리즘과 비교, 분석한다.

n명의 사용자들 중 k명 이상이 모이면 시스템의 비밀정보가 재구성 되는 시스템을 threshold cryptosystem 이라고 한다. 1979년 Adi Shamir에 의해 threshold 개념이 제안된 이래로, 그 현실적인 효용성때문에 많은 연구들이 이루어져 왔다. Threshold cryptosystem을 구성하기 위해서는 n명의 사용자들이 각자의 share를 가지고 있어서 그 중 k명 이상이 자신의 share를 밝히면 시스템의 비밀정보가 재구성된다. 그러나, 시스템의 비밀정보가 재구성 된 후에는 각 사용자들의 share를 재분배해야 한다. 이러한 특성은 반복적으로 전자서명과 같은 비밀연산을 수행해야 하는 응용에서는 비현실적이 된다. 이러한 경우에 적용시키기 위한 암호시스템이 threshold signature이다. (t, n)-threshold signature 시스템에서는 n명의 사용자들 중 k명 이상이 자신의 share를 이용한 부분서명을 수행하면 전체 시스템 서명이 생성된다. 그러나, 시스템의 비밀정보는 재구성 되지 않으므로 아무도 알 수 없고, 따라서 재분배 할 필요가 없다. 본 논문에서는 이러한 threshold signature 시스템에 대한 연구결과들을 살펴본다.

With the recent advancement of technology, there has been an increase in professional development activities, including teachers using blogs to share practical knowledge and reflect on teaching and learning. This study was conducted to identify the contents of practical knowledge shared through the K-12 teachers' blogs. To achieve the research objective, 70,571 blog posts were collected from 329 blogs of K-12 teachers in Korean and analyzed using text mining techniques. The results of the study are as follows. First, practical knowledge sharing activities using teacher blogs have increased. Teachers posted a lot of blogs during the semester. Second, primary school teachers share various curriculum activities, reflections on project classes, class management, opinions related to education, and personal. Third, secondary school teachers share summaries and reviews of curriculum, materials related to college entrance exams, various instructional materials, opinions related to education, and personal experiences on their blogs. This study suggested that blogs are widely used as a venue for sharing practical knowledge of teachers, and that blogs can be a useful way to develop professionalism.

This study investigates the specific and conclusive reasons why a company issues bonus shares, as well as the rationale and the best timing for bonus share issuance. The study examines Carlsberg's annual reports from 1988 to 2004 to evaluate the factors that influence bonus share payments and timing. Examine supporting evidence from other businesses as well. An analysis of Carlsberg Brewery Malaysia Berhad's bonus shares granted from its inception to 2004 found that the announcement of bonus shares would increase the company's share price. As a result, the findings suggest that bonus shares are issued to correct market asymmetry. This research supports the idea that issuing bonus shares would increase the stock price, resulting in increased liquidity. Hence, companies issue bonus shares to boost their liquidity and to convey private positive information to their shareholders. This research adds to the literature by focusing on the timing and key features of bonus share issuing. It implies that dividend policy should be customized to market imperfections. As a result, dividend policies would differ significantly between organizations based on the weights each of the imperfections has on the firm and shareholders.
