Ten new species of genus Sarcotragus (Demospongiae: Dictyoceratida: Irciniidae) are described from Geomundo Island and Jejudo Island, Korea. All new species of the Sarcotragus are distinguished from the other reported species of Sarcotragus by the skeletal structure, especially fasciculate primary fibres. The characters of genus Sarcotragus have cylindrical primary fascicles filled with wads of filaments or flattened fascicles. All of the primary fibres are not cored with foreign debris. Secondary fibres have slightly fasciculate branch or plastic-like web. They are all not cored with foreign debris. All skeletal fibres are very irregular. The surface is covered with loose or tight filamentous membrane.

Nine new species of genus Ircinia (Demospongiae: Dictyoceratida: Irciniidae) from Jejudo Island, Korea are described. All of the new species are distinguished from the others reported species of Ircinia by the skeletal structure, especially massive fasciculate primary fibres. The characters of genus Ircinia have primary fibres cored with foreign debris and no cored secondary fibres. Primary fibres are not easy to distinguish from secondary fibres if they are not cored. Secondary web has perforated plate or meshed net. All new species have loosely arranged skeletal fibres network.

Two new species of the genus Luffariella (Dictyoceratida: Thorectidae), L. tubula n. sp. and L. koreana n. sp. were collected from Jeju-do, Korea. These species differ significantly from the previously reported five species in terms of shape and skeletal structure. L. tubula n. sp. has two categories in thickness of secondary fibres which were different from other species. L. koreana n. sp. is very similar to L. variabilis from Tahiti in skeletal structure, but differs in sponge shape with irregular branching and indistinct surface conules. Primary fibres of the two new species are separated from secondary and tertiary fibres.

Post-transcriptional nucleotide sequence modification of transcripts by RNA editing is an important molecular mechanism in the regulation of protein function and is associated with a variety of human disease phenotypes. Identification of RNA editing sites is the basic step for studying RNA editing. Databases and bioinformatics resources are used to annotate and evaluate as well as identify RNA editing sites. No method is free of limitations. Correctly establishing an analytic pipeline and strategic application of both experimental and bioinformatics methods constitute the first step in investigating RNA editing. This review summarizes modern bioinformatics approaches and related resources for RNA editing research.

South Korea and Mongolia are both the member countries of the World Trade Organization, but neither was the country with FTA. Nowadays, South Korea widely concludes the FTA with other countries, and the trade area has extended toward the neighboring continents and seas. Mongolia is a country with smallest economic entity but large in area and with abundant underground resources. And it's a main strategic zone of Eurasia. After the disintegration of the Soviet Union, Mongolia began to turn to market economy, and eagerly made effort to open and reform. With the expanse of trade and economy cooperation between South Korea and Mongolia, Mongolia started its sea road expanding. And the south Korea went to inland to get the necessary resources. Both of them feed its needs and obtain its profits.

전략적 비지니스 동맹의 형성은 많은 국가에 있어서 산업전반에 걸쳐 점차 유력한 전략적 목표가 되고 있다. 국내 전략적 동맹 모델을 국제 모델로 확장할 수 있는 가능성이 있다. 세계적인 전략적 비지니스 동맹은 세계적으로 불확실한 경쟁 상태의 환경하에서 안정확보와 위험요소를 줄일 수 있을 것이다. 국제적인 구매자와 판매자를 연결시킬 가능성이 있는 기술은 완전히 개발되어 있으나, 빠른 속도로 이용되지 못하고 있다. 국제 임산물 무역에 있어서 판매자와 구매자가 기술을 채택하는데 점점 복잡해짐에 따라 장래에 전략적 동맹은 계속해서 발전할 것이다.

Current research on Internet of Things (IoT) has primarily addressed the means to enhancing smart resource allocation, automatic network operation, and secure service provisioning. In particular, providing satisfactory security service in IoT systems is indispensable to its mission critical applications. However, limited resources prevent full security coverage at all times. Therefore, these limited resources must be deployed intelligently by considering differences in priorities of targets that require security coverage. In this study, we have developed a new application of Cognitive Radio (CR) technology for IoT systems and provide an appropriate security solution that will enable IoT to be more affordable and applicable than it is currently. To resolve the security-related resource allocation problem, game theory is a suitable and effective tool. Based on the Blotto game model, we propose a new strategic power allocation scheme to ensure secure CR communications. A simulation shows that our proposed scheme can effectively respond to current system conditions and perform more effectively than other existing schemes in dynamically changeable IoT environments.

With the increasing importance of ecosystem in a business environment, the value of open innovation is receiving great attention. Under open innovation, companies open their knowledge, capital, and other resources to cooperating companies; on the other hand, under closed innovation companies depend solely on their own resources. In this paper, we compare closed and open innovation using the simulation method, and confirm that in terms of total capital and production of the industry, open innovation provides greater opportunities to the entire ecosystem. Moreover, Schumpeterian competition, which is a dynamic of closed innovation, functions even under open innovation. Our findings highlight that not only small but also large companies can receive the benefit of an enlarged industry under open innovation.

본 연구는 로컬 거버넌스의 구성 파트너로서 특정 지역에 입지하고 있는 기업이 사회적 책임수행의 차원에서 지역사회와 어떤 관계에 있는지, 그리고 기업의 사회적 책임 수행이 그 지역사회의 지속가능성에 어떤 영향을 미치는지 논의했다. 사회공헌활동을 비롯하여 기업이 다양한 방식으로 사회적 책임을 수행하는 것은 지역사회가 기업의 이해관계자이기 때문이다. 따라서 기업의 사회적 책임 수행은 기업 이미지 개선, 장기적으로 교화된 자기이익 추구, 지역사회와 연대 강화를 위한 전략의 일환으로 해석할 수 있다. POSCO 광양제철소의 경우, 법적 윤리적 수준의 자기규제 책임 수행 차원의 지역 협력활동으로부터 보다 고차적인 사회공헌활동에 이르기까지 다양한 형태의 사회적 책임 수행을 추구함으로써 지속가능기업으로서의 기본적 특성들을 갖춰가고 있다.

Most developing countries are experiencing rapid urbanization and the associated growth of industry and services. Cities are currently absorbing two-thirds of the total population in the developing world. Korea has about 85 percent of urban dwellers. World population will shift from being predominantly rural to predominantly urban around the turn of the century. Although cities play a key role in development process and make more than a proportionate contribution to national economic growth, especially cities are also the main catalysts of economic growth in developing countries, they can also be unhealthy, inefficient, and inequitable places to live. Most developing countries are increasingly unable to provide basic environmental infrastructure and services, whether in the megacities or in secondary urban centers. Of particular concern is the strain on natural resources brought by the increasing number of people, cars, and factories. They are generating ever greater amounts of urban wastes and emissions. They also exceed the capacity of regulatory authorities to control them and of nature to assimilate them. The environmental consequences are translated into direct negative impacts on human health, the quality of life, the productivity of the city, and the surrounding ecosystems. Environmental degradation threatens the long tenn availability and quality of natural resources critical to economic growth. Cities, with their higher and growing per capita energy use for domestic, industrial, and transport purpose also contribute a disproportionate share of the emission leading to global warming and acid rain. An important priority is to develop strategic approaches for managing the urban environment. The design of appropriate and lasting strategic responses requires first an understanding of the underlying causes of urban environmental deterioration, it is necessary that longer tenn objectives should be set for urban area to avoid irreversible ecological damage and to ensure lasting economic development. As a means to the preventive policies against the adverse effect, environmental impact assessment (EIA) serve to identify a project's possible environmental consequences early enough to allow their being taken into consideration in the decision making process for urban planning. This paper describes some considerations of EIA for urban planning-scoping, assessment process, measurement and prediction of impacts, pollution controls and supervision, and system planning for environmental preservation.
