Combinatorial testing has been an active research area in recent years. One challenge in this area is dealing with the combinatorial explosion problem, which typically requires a very expensive computational process to find a good test set that covers all the combinations for a given interaction strength (t). Parallelization can be an effective approach to manage this computational cost, that is, by taking advantage of the recent advancement of multicore architectures. In line with such alluring prospects, this paper presents a new deterministic strategy, called multicore modified input parameter order (MC-MIPOG) based on an earlier strategy, input parameter order generalized (IPOG). Unlike its predecessor strategy, MC-MIPOG adopts a novel approach by removing control and data dependency to permit the harnessing of multicore systems. Experiments are undertaken to demonstrate speedup gain and to compare the proposed strategy with other strategies, including IPOG. The overall results demonstrate that MC-MIPOG outperforms most existing strategies (IPOG, IPOF, IPOF2, IPOG-D, ITCH, TConfig, Jenny, and TVG) in terms of test size within acceptable execution time. Unlike most strategies, MC-MIPOG is also capable of supporting high interaction strengths of t > 6.

The aim of this paper is to analyze China's naval strengthening and threat reflected in submarines, aircraft, destroyers and missile capabilities and US Navy's counter-forces. China is strengthening its naval forces in accordance with its three-step naval force build-up plan, and the introduction of Russian destroyers and submarines is a foothold for China's naval enforcement. The Chinese Navy also converted the concept of the First-Second Island Chain Defense, which it had already maintained, to the concept of maritime layer defense. Currently, the Chinese Navy maintains the concept of a Three-Maritime Layer Defense which includes the South China Sea, where artificial islands are being built by China, in the First Layer Defense and the East China Sea in the Third Layer Defense. Along with the advancement of Chinese Navy's submarines, surface vessels and aircraft's operational capabilities, ballistic and cruise missile capabilities become a major threat to the US Navy. If a crisis occurs in the East China Sea or in the Taiwan Waters, the US Navy will face more difficulties in employing the Carrier Strike Group to manage the crisis. Meanwhile, if a crisis occurs on the Korean Peninsula, it will be a burden to dispatch Carrier Strike GroupS to the East and West Seas of the Korean Peninsula. For the stable future, the US Navy should develop a strategy to respond more effectively to the Chinese Navy, which is challenging new maritime supremacy in East Asia.

IT는 한국의 경제성장에 큰 기여를 해왔으며 사회전반의 패러다임 혁신을 통해 생산성, 효율성, 편의성, 소통성을 증진시키고 삶의 양식에 전면적 변화를 가져왔다. 국민경제와 사회문화에서 지대한 의미를 지나는 IT는 다른 기술 또는 산업과의 융합이라는 새로운 변화와 혁신의 중심에 위치하고 있다. IT융합은 IT의 자체 고도화를 바탕으로 다른 분야의 기술개발과 산업발전을 견인하거나 새로운 산업을 창출하는 것으로 우리나라를 비롯하며 주요국에서는 자원과 역량을 선택적으로 집중하고 있다. 이 논문에서는 IT 융합과 관련된 주요국의 산업 전략 및 기술개발 동향을 파악하고 전문가 설문조사결과를 바탕으로 한국의 IT 융합역량의 수준을 평가하고 결론적으로 IT융합신산업육성 및 선도방안에 관한 전략적 제언을 하고자 한다.

Early, aggressive nutrition is an important contributing factor of long-term neurodevelopmental outcomes. To ensure optimal growth in premature infants, adequate protein intake and optimal protein/energy ratio should be emphasized rather than the overall energy intake. Minimal enteral nutrition should be initiated as soon as possible in the first days of life, and feeding advancement should be individualized according to the clinical course of the infant. During hospitalization, enteral nutrition with preterm formula and fortified human milk represent the best feeding practices for facilitating growth. After discharge, the enteral nutrition strategy should be individualized according to the infant's weight at discharge. Infants with suboptimal weight for their postconceptional age at discharge should receive supplementation with human milk fortifiers or nutrient-enriched feeding, and the enteral nutrition strategy should be reviewed and modified continuously to achieve the target growth parameters.

The purpose of this paper is to increase the competitiveness of firms by establishment of green marketing strategy and its application to a new alternative energy development, ultimately contributing to the advancement of national economy. This study adopted an integrated approach to develop a strategic theory of 'Sun Tzu on the Art of War' that is one of the oldest military treaties and still applicable to today's management development. It applies to the empirical result from a new alternative energy development. For more qualitative improvement of this paper, it needs further detailed studies in both theory and practice in green marketing theory that is applicable to the new alternative energy development.

Since the profess of the reformation and opening Policy in 1978, China has been outstandingly developed its economy and increased the real scale of its economy 4 times as big as before, and is expected to rise as a superpower holding in check U.S.A even in economy as well as politics, military affairs and diplomacy in the 21st century. In this position, China has constantly tried to join WTO since 1986, as an effort to gain a status in the international society. It hsa been making various economic reformations to provoke a crustal movement in its own economy such as tariffs lowering measurement for the almost whole items, remove of restriction of import items, lowering the refunding rate of over deposit tax and annihilation of the special treatments for the foreign investment. In short, recently Chinese government is cutting down the special treatments for the foreign capital enterprises and changing the policy to the direction of gradually reinforcing the control, so it requires that our enterprises trying to advance and invest in China have to consider these carefully. Investment in China of our enterprises become serious since 1990 is focused on such labor intensive industries as textiles, sewing and shoes which lost the competitive power due to the wage increase. Particularly, Pusan economy having played the role of locomotive for Korean economy in the past developing period has been weakened in the competitiveness and not yet activated in 1990s. In terms of this, the enterprises engaged in such typical industries of Pusan as shoes, textiles and sewing have borne much fruit from the investment in China with abundant and cheap labors. However, from a few years the enterprises in Pusan invested in China due to the cheap labors and rich resources and invested in China have suffered much troubles and failures more and more resulted from the advancement without sufficient previous knowledge and information related to the investment including investment environment. Therefore, at the time of advancement in China, Korean enterprises should make their decision related to the investment, after taking these investment environment into account previously to a full extent and making an investment strategy.

본 연구는 제1, 2차 도서관발전종합계획상의 '도서관 행정체계 일원화' 과제의 추진성과 분석과 정책 평가를 통해 해당 정책과제의 중요도, 타당성 등을 고찰하고, 일원화 추진방안의 쟁점사항에 대한 검토를 통해 도서관 행정체계 일원화에 대한 추진전략을 모색하고자 시도되었다. 제1차 도서관발전종합계획에서의 성과 분석에서는 구체적이고 실질적인 실적이 전무한 거의 선언적인 정책과제로 밝혀졌고, 도서관전문가 집단을 대상으로 수행한 제2차 도서관발전종합계획상의 정책 평가에서는 실현가능성이나 구체성이 떨어지는 정책과제로 평가되었다. 선행연구 조사, 전문가 정책 평가, 현장 실무자에 대한 심층 면접조사 결과 지자체로 일원화하는 일원화 주체에 대한 정책방향은 타당한 것으로 나타났다. 하지만 일원화 방식, 조직구성, 인력 이관 및 직급 조정, 재산 이관 등에서 상당한 쟁점이 있음이 분석되어, 도서관 행정체계 일원화를 위해서는 거시환경 차원의 구호성 정책이 아니라 과업환경 차원의 실현가능한 실질적이고도 구체적인 실천 전략이 필요함이 판단되어졌다.
