Purpose: This study examines the attitude of South Korean adults toward food aid to North Korea and factors associated with it. Methods: An online survey involving 1,000 adults aged 19-69 years was conducted between September-October 2019. Throughout South Korea, the subjects were proportionally distributed with respect to gender, age, and region, to represent South Korean adults. Results: A total of 44.6% of the respondents agreed (Agreement group), 36.7% disagreed (Disagreement group), and 18.7% neither agreed nor disagreed to food aid to North Korea. Compared to the Disagreement group, the Agreement group had a higher concern of food aid to North Korea and a more positive perception on the effect of it. The Agreement group selected "direct assistance from the government" whereas the Disagreement group chose "support through international organizations" as the most appropriate channel for food aid to North Korea. Logistic regression analysis revealed that South Korean adults showing a more positive perception on the effect of food aid to North Korea were more likely to agree to the aid (odds ratio [OR], 19.32). Moreover, compared to the conservatives, the progressives were more likely to agree to food aid to North Korea (OR, 5.94). South Korean adults in their 40-50s were more likely to agree to food aid to North Korea than those in their 20-30s (OR, 2.81). South Korean adults with a higher concern of food aid to North Korea (OR, 3.93) and a greater positive perception on Korean unification (OR, 1.88) were more likely to agree to food aid to North Korea. Conclusion: The most important factor associated with the attitude of South Korean adults toward food aid to North Korea was their perception on the subsequent effect. As strategies to draw social consensus on food aid to North Korea, we recommend systematizing the monitoring process on the effect of providing food aid to North Korea and informing the public of the outcomes.

최근 대체수자원 개발, 도시 비점오염과 물순환 체계의 효율적 관리를 위한 분산식 빗물관리기술에 대한관심이 급증하고 있다. 이수 목적의 빗물이용시설, 치수목적의 우수유출 저감시설, 택지개발사업의 재해저감시설 등 다양한 목적으로 시설들이 도입되고 있다. 그러나 치수용 시설에 있어 설계강우에 따른 홍수량 산정방법을 제외하고는 이수 및 물순환 건전화를 위한 계획, 설계기술은 현재까지도 부족한 실정이다. 특히 이수목적의 경우 집수면의 토지이용 특성, 용도별 사용수량 및 경제성에 대한 검토 없이 집수면적이나 대지면적의 일정비율 이상을 설계하고 있는 실정이다. 본 연구에서는 국내에서의 빗물관리시설 계획 설계를 지원하기 위해 공동주택 빗물관리 의사결정지원 모형(RainCity v1.5 Beta)을 개발하였다. 강우자료는 5분 간격의 설계강우, 시우량 및 일 강우자료를 DB나 사용자 파일로부터 호출하도록 하였으며, 토지이용 특성에 따라 유출계수를 고려한 수문학적 집수면적을 산정하여 적용하였다. 현재 버전은 이수 및 치수용 저류조, 침투통, 침투트렌치, 침투블럭 등 장치형 침투시설과 투수성포장 등 지표면 침투시설을 대상으로 하였으며, 각 시설조합의 설치에 따른 유입/유출량, 침투량 및 사용수량 등 물순환 과정을 모의할 수 있다. 특히 선택된 시설조합은 규모 시나리오에 따라 목표 기능에 맞는 시설규모들을 선정하고, 비용-편익분석을 통해 경제적인 시설규모를 결정할 수 있다. 향후 지속적으로 GUI를 개선하여 사용자 편의도를 높이고, 식생형 침투도랑, 생태연못, 중수이용시설과의 연계 등 기능을 확대할 계획이므로 국내에서의 빗물관리시설의 계획 설계 시 활용도가 높을 것으로 기대된다.

전기기술은 기술의 특성상 민간에 대한 유인이 적은 공유성 기술이나 대학 또는 기업이 감당하기 어려운 대형복합기술의 비중이 높으며, 최근 들어 전력산업의 구조개편 등에 따라 국가적 기술개발수요가 확대됨과 동시에 전기기술의 이용분야 확대와 타 기술과의 융합화 및 대형화로 신기술수요가 늘어나고 있다. 현재 우리 나라의 전기기술 R&D체제에서는 공공기술에 대한 사각지대가 발생하고 있음에도 불구하고 국가차원의 R&D 공급이 미약하여, 거대한 시험설비와 첨단고가장비를 필요로 하는 시스템기술로 일부 기기나 시스템운용을 제외하고는 개별기업이나 전력회사에 대한 기술개발 유인이 크지 않으며, 따라서 전기기술분야의 R&D 실태 파악과 역할에 대한 검토를 통해 R&D 주체별 기관특성에 맞는 국가 R&D체계의 정립이 필요한 실정이다. 따라서, 앞으로는 전기기술분야의 국가 R&D 목표 및 기본전략에 따라 국가 R&D 자원의 규모, R&D 주체간의 역할분담 등 전반적인 R&D 체계의 구축이 선행되어야 하며, 이를 통해 기관별 Mission 및 고유기능을 토대로 전문성 제고와 특성화를 유도할 수 있는 연구여건의 조성이 시급하다 하겠다. 특히, 장기대형연구, 원천기술연구, 기초기반연구, 연구기반구축, 인력양성 등 필수적 국가기능에 대해서는 기관별 특성에 따라 안정적인 역할수행이 가능하도록 역할분담 및 정책적 지원을 하되, 그 밖의 영역이나, 민간 및 전력회사의 독자적인 R&D에 대해서는 경쟁 및 협력을 통한 연구효율성 향상을 유도하는 방향으로 나가는 것이 바람직할 것이다. 국가적 전력기술 R&D의 효과적인 수행과 실효성 확보를 위해서는 재원확보가 선행되어야 하며, 이를 위한 방안으로는 기존의 전력사업자에게는 기술개발충당금 또는 전기요금 중 일정비율을 국가적 R&D 재원으로 설정할 수 있을 것이며. 신규 사업자에게도 규제비용의 차원에서 일정 부담금을 부과하는 방법이 가능할 것이다. 이러한 재원을 가지고 사업성격 및 R&D 유형에 따라 역할분담에 따른 지원, 정책적 사업, 경쟁적 사업공모 등을 통해 지원분야 및 규모, 대상기관 등에 대한 선별적인 지원이 이루어져야할 것이다.

In this paper, 18 railway stations in Gyunggi-do are selected as metropolitan transfer centers out of 203 stations based on three elements. They are the number of passengers, the level of connection transport, and the level of relevant plans. For 18 stations the level of service (LOS) is analyzed for connection transport system. As a result, half of them are found to be below LOS "D". In order to maximize the use of those railway stations, a method is proposed to upgrade the level of service to "C" above. Finally, the improvement plans are suggested for two acts. In the Special Act on Metropolitan Traffic Management of the Metropolitan Region, the central government financial support ratio is suggested from 30% to 50%, from "necessary costs" to "total costs." In the Act on National Integrated Transport System Efficiency, 50% for connection road and 70% for connection raiway are suggested.

With technology scaling, soft error rate has greatly increased in embedded systems. Due to high performance and low power consumption, VLIW (Very Long Instruction Word) architectures have been widely used in embedded systems and thus many researches have been studied to improve the reliability of a system by duplicating instructions in VLIW architectures. However, existing studies have ignored the feature, called VLES (Variable Length Execution Set), which is adopted in most modern VLIW architectures to reduce code size. In this paper, we propose how to support instruction duplication in VLIW architecture with VLES. Our experimental results demonstrate that a VLIW architecture with VLES shows 64% code size decrement on average at the cost of about 4% additional cell area as compared to the case of a VLIW architecture without VLES when instruction duplication is applied to both architectures. Also, it is shown that the case with VLES does not cause extra execution time compared to the case without VLES.

The purpose of this study was to examine the screening and its validation of children with language developmental delay in child care and education centers, the response of parents with children with language developmental delay and the assistance needs of child care and education teachers for those children. Teacher interview with semi-structural method, transcription and content analysis method were used. The subjects in this study were 13 teachers and 30 infants and toddlers with language developmental delay in 10 child care and education centers in Seoul. The findings of the study were as follows: First, the child care and education teachers screened children with language developmental delay in their classes based on their verbal characteristics and maladjusted behavior. Their screenings were turned out correct. Second, as for the response of parents, the parents who had children with language developmental delay were indifferent, were aware of the fact in advance or asked the teachers for counseling on their children's language developmental delay. Third, the teachers couldn't provide the appropriate supports for the children in needs. Fourth, regarding the assistance needs of the child care and education teachers, they called for assistance from specialists and professional institutions, and wanted to receive education on language development. Besides, they asked for relevant supporting materials and screening criteria, and considered it necessary to reduce the ratio of teacher to children.

The aims of this study is to analyze the effectiveness of firms financial status quo and the scale of financial support on SMEs overall performance. We have gathered the financial guarantee data from 1998 to 2013, provided by Korea Credit Guarantee Fund (KODIT), to analyze the effectiveness of Financial policy. To classify both financial status quo and scale of financial support, we utilized the following variables; Interest Coverage Ratio (ICR) and newly guaranteed amount ratio. To take the measurement of the overall performance, we employed profitability, growth ratio and activity index. To minimize the effect of repeated financial support (redundancy benefits), firms were selected based on the following criteria: firms that receive no financial support prior to implementing such policy over the last 3 years and no new financial support over the last 2 years. Results suggest that firms with higher ICR and large newly guaranteed amount influence on financial performance in terms of profitability index. Firms with lower ICR and large scale financial support showed a better performance compare to firms with small-scale financial support. Firms with large-scale financial support, irrespective of ICR inclined to have better performance to those of small-scale financial support in terms of growth index. For activity index, however, firms with large scale support led to higher performance in the short term. In turn, our analysis presents objective perspective with respect to the effectiveness of financial policy through credit guarantee on overall performance of SMEs. This study, therefore, implies that well-balanced SMEs supporting policy may lead to better directions.

The Hierarchical Mobile IPv6 (HMIPv6) has been proposed to accommodate frequent mobility of the Mobile Node. HMIPv6 can effectively reduce the signaling overhead and latency. However, it has a problem that the registration of a mobile node concentrates on the furthest MAP(Mobility Anchor Point) when the mobile node enters into a new domain. This paper proposes a new load distribution mechanism by using the concept of Nash Bargaining Solution. The main advantage of the proposed scheme can prevent load concentration from being registered to the specified MAP based on the weight value according to the available resource-ratio of a MAP. With a simulation study, the proposed scheme can improve network performance under widely diverse traffic load intensities.

최근 신재생에너지의 보급 정책으로 인해 태양광 또는 풍력과 같은 신재생에너지가 전체 전력 계통에서 차지하는 비율이 증가되고 있는 실정이다. 그러나 신재생에너지는 변동 적이기 때문에 계통의 안정성을 저해하는 원인이 될 수 있다. 이에 따라 각 나라에서는 계통 안정성을 위한 기능들을 요구하고 있으며, 그 요구는 점차 강화되고 있다. 이와 같이 신재생에너지 비율의 증가로 인해 계통 안정성에 대한 문제가 강조되고 있지만, 태양광 분산 발전 시스템의 경우에는 일사량에 의존하여 운전하기 때문에 일사량이 낮거나 야간에는 계통 안정성을 위한 기능을 수행하지 못하는 단점이 있다. 본 논문에서는 일사량이 낮거나 야간에도 계통 안정화를 위해 무효전력 지원이 가능한 확장된 무효전력 운전(EF-RPO: Extended feed-in Reactive Power Operation)방법의 제어 전략을 제안하며, 제안한 방식은 1MVA 계통 연계형 인버터의 제작과 실험을 통해 검증하였다.
