This study focused on cases that led sustainable urban development through the construction and utilization of organic greenery systems linking green spaces of urban peripheries with metropolitan areas. To that end, Berlin - Brandenburg's regional parks in Germany and Milan's Raggi Verdi, a radial green axis project, in Italy were selected for analysis as case studies. As frameworks for this analysis, this study has established existing infrastructure accessibility and linkage, recycling and cooperative management. The results of the case study analysis are as follows: First, the specialized spatial strategy based on the individuality of the green space outside the city rather than a uniform landscape was used as the foundation of the sustainable development plan. Second, physical linkage from the center of the city to the periphery contributed to the sustainable development of the overall metropolis by improving the economic value of the surrounding area as well as ecological and environmental values. Third, the central management system was established to reduce the administrative inconvenience caused by multiple administrative districts in the green space of urban periphery. The implications of applying the above results to Seoul, Korea are as follows. First, it is necessary to establish a differentiation strategy by re-establishing the identity of a green landscape in the urban periphery, because the green spaces of Seoul's periphery are dispersed and mostly have a repetitious mountain landscape. Also, it is necessary to actively link peripheral mountains and urban green areas to create ecological value and economic value, and ultimately to help the sustainable development of the city. Finally, building an integrated management system is required to solve fragmented green space management departments in most of the urban periphery's green spaces. In conclusion, this study shows the significant possibility that the sustainable development of a metropolis can be derived from the utilization, linkage, and management of the green space in the urban peripheries, which is extraordinary compared to normal centralized urban development.

Under the market economy of capitalism, several limitations reveal the inequity and redistribution problem of wealth, inefficiency of over-manufacturing and over-consumption, pollution of the natural environment, and the constraint of human liberty and dignity. The new challenge of symbiotic relationships that encourage individual corporations coincides with the need to practice social responsibility and share values to overcome these limitations. Social economy and the social enterprises that simultaneously pursue the making of corporate private profits and the realization of social values have been suggested and disseminated as alternative social value creators. Furthermore, the concept of a sharing economy, which refers to the sharing of things rather than owning them, is growing traction as a new paradigm of capitalism. However, these efforts of social enterprises have fallen short against the conflicts between private profit and social values. This study deals with the case of a start-up social corporation, "Purun Bike Sharing Inc.," which is based on a regional sharing economy business model about bike rental services that use Information and Communication Technology (ICT). This corporation pursues harmonic management to achieve a balance between private profit and social value. Its corporate mission is to achieve sharing, coexistence, and contribution for public welfare. This mission is a possible idea for use in the local community network as a core key for sustainable social enterprises. The model can also be an alternative approach to overcome the structural friction in the social corporation. This study considers the case of Purun Bike Sharing as a sustainable way to practice a sharing economy business model based on a regional cooperation network, which can be combined with social value, and to apply ICT to a sharing economy system. It also examines the definition and current state of social enterprises and the sharing economy, and the cases of the sharing economy business model for the review of prior research.

This study reviews three eco-friendly energy towns with hybrid thermal energy supply systems and borehole thermal energy storage (BTES) in Canada and Denmark. The district heating and cooling systems were designed by using multi-source energy for the higher efficiency and reliability as well as environment. ADEU (Alexandra District Energy Utility) located at the developing area in the city of Richmond, Canada was designed to supply district energy with the installation of 726 borehole heat exchangers (BHEs) and a backup boiler using natural gas. DLSC (Drake Landing Solar Community) located in the town of Okotoks, Canada is a district system to store solar thermal energy underground during the summer season by seasonal BTES with 144 BHEs. Brædstrup Solpark district heating system located in Denmark has been conducted energy supply from multiple energy sources of solar thermal, heat pump, boiler plants and seasonal BTES with 48 BHEs. These systems are designed based on social and economic benefits as well as nature-friendly living space according to the city based energy perspective. Each system has the energy center which distribute the stored thermal energy to each house for heating during the winter season. The BHE depth and ground thermal storage volume are designed by the heating and cooling load as well as the condition of ground water flow and thermophysical properties of the ground. These systems have been proved the reliance and economic benefits by providing consistent energy supply with competitive energy price for many years. In addition, the several expansions of the service area in ADEU and Brædstrup Solpark have been processed based on energy supply master plan. In order to implement this kind of project in our country, the regulation and policy support of government or related federal organization are required. As well as the government have to make a energy management agency associated with long-term supply energy plan.

This study was conducted in order to understand nutrition teachers (dietitians)' perceptions of barriers to implementation of HACCP system in school foodservices in Gyeongnam, Korea. Questionnaires were distributed to 350 nutrition teachers (dietitians) from November to December of 2009, and 214 were collected and analyzed. The results of this study were as follows. First, nutrition teachers (dietitians) recognized the following as barriers in implementing the HACCP system: 'the status of facilities and utilities'> 'monitoring'> 'work satisfaction'> 'foodservice employees'> 'cooperation of HACCP team'> 'cooperation of persons concerned besides foodservice employees'> 'understanding the HACCP system'. Second, total working experience was found to be the factor most affecting 'cooperation of HACCP team (p<0.01)', 'cooperation of persons concerned besides foodservice employees (p<0.01)', 'foodservice employees (p<0.05)', and 'work satisfaction (p<0.05)'. Further, 'the status of facilities and utilities' was significantly affected by 'construction/reconstruction of kitchen (p<0.01)', 'division of kitchen area (p<0.01)', 'existence of preliminary preparation room (p<0.01)', and 'existence of dishwashing room (p<0.01)'. Third, dietitians perceived the following concerning hindrance factors of the HACCP system according to CCP stage: 'CCP 1'> 'CCP 3'> 'CCP 2, 'CCP 6'> 'CCP 4'> 'CCP 8'> 'CCP 7'> 'CCP 5'. In conclusion, this study showed that nutrition teachers (dietitians) in the Gyeongnam area recognized 'the status of facilities and utilities' from HACCP areas and 'CCP 1 (menu planning)' from CCP stages as the greatest barriers to implementing the HACCP system in school foodservices. To implement the HACCP system successfully in school foodservices, facilities and utilities should be properly equipped, and menu planning training for nutrition teachers (dietitian) should be conducted.

In this paper, a plan to expand the scale of the domestic MRO industry was proposed by finding the technical common points between the aviation MRO and naval vessel MRO industries. The aviation MRO industry is led by Europe, North America, and Singapore. Europe and North America have very large aviation industries. The reason for the development of the MRO industry in Singapore is that the aviation MRO and ship MRO industries gathered to expand the industrial scale. The MRO field is an industry that spans all fields from research & development, production, manufacturing, operation, disposal, and crew training. The MRO industry is divided into military and civilian use. However, most of them are only differences in the needs of users, and there are no significant technical differences. The weapon system used by the military is steadily developing. It is impossible for the military to maintain all equipment at a time when troops are reduced. For that reason, it is necessary to share roles in each field. There is a need for an MRO industry in which civil and military operations cooperate to maintain all weapon systems at optimal performance. And the MRO industry development should be based on the civil market. The scale of the MRO industry should be expanded by gathering equipment commonly used in aircraft and naval vessels. This can increase military availability and reduce maintenance budgets.

Computing systems in the modern era are expanding rapidly to include mobile-based businesses that make us of the various convergence distributed business process. This has lead to growing interest in the field of mobile embedded software development methodology, which has in turn lead to the proliferation of the embedded mobility. The use of CBD (Component Based Development) provides reusability, maintainability and portability, all of which are very important and focus issues to the business process. It also comes with the inherent productivity, quality and reliability of CBD. To make efficient use of CBD, though, clarified interface definitions for component integration are necessary. These definitions should be made up of collaborative hierarchical and horizontal architecture layers. Successful definitions should apply an effective framework made up of the architecture and process. In this paper, we describe an interface specification for small grained mobile embedded components(MEC) for the mobile embedded domain to meet maximum user requirements. We build and deploy the reconfigurable design patterns and components (in business domain categories) to make a component hierarchy and business logics for mobile embedded software. Proposed components specification plays a major role in development of the software for handling inconsistency in existing specification. It also includes plenty of specification information, using semantics and modeling based mechanisms to support business processes. We propose a development model of mobile embedded software using CBD for very complex and dynamic mobile business. We can apply it in a plug and play manner to develop the software. We verify that our framework supports very good productivity, quality and maintainability to meet the user's requirements in mobile business.

The labor contract Law has been prepared as an important solution for social stability. After long disputes around the orientations of the law, On June 29, 2007, the new Chinese labor contract law is passed. This law reflects the changing labor relations because of economic reforms like restructuring of the state-owned enterprises and so on. This law contains more market-oriented clauses that are supplemented by corporatist scheme supported by trade unions than the first draft. This law emphasize labor's rights and interests to remove prior labor contract problem. So Chines government see this law as standard law to restructure social relationship and also require firms to corporate social responsibility. Therefore, implementation of the new Chinese labor contract law bring about increasing labor cost, infringement of autonomy for human resource management, rigidity of industrial relations. Under these situation, Korean shipping and port logistics companies need to introduce management system of minimized employment, prepare human resource management in response to long-term employment, maintain favor relationship with trade union, and set up counteiplan about risk of a labor dispute.

개념적으로 존재하던 클라우드 컴퓨팅의 사용이 본격적으로 심화되면서 기업들의 클라우드 컴퓨팅에 대한 개념과 생각에도 많은 변화가 생기게 되었다. 클라우드 컴퓨팅 구축이 더욱 가속화되는 가운데, 그로 인한 비용절감이나 투자수익 창출 효과에 대한 검증이 활발해질 것으로 예측됐다. 시대를 뒤바꾸는 혁신적인 기술도 잇달아 등장할 것이란 기대도 높다. 2013년은 클라우드 컴퓨팅의 발전에 또 한번의 변곡점이 될 것으로 전망된다. 본 고에서는 2013년 클라우드 컴퓨팅에 관한 예측 몇 가지를 살펴보고자 한다. 첫째, 중소기업에서의 클라우드 컴퓨팅 사용 및 정착이 가속화될 것으로 보인다. 대기업의 경우에는 기존에 구축되어 있는 IT 시스템에 대한 거버넌스 체계를 완성해 나가고 있는 상황 속에서 중앙집중형과 사용자 편의성이 강화된 클라우드 컴퓨팅을 도입하기 위해서는 아직 추구 해야 할 과제가 많다. 하지만 중소기업은 예산을 문제로 대기업과 같은 수준의 IT 인프라를 갖추지 못하고 있기 때문에 클라우드 컴퓨팅 도입으로 비용대비 고효율의 IT 인프라를 갖출 수 있다. 둘째, CSP, CSB와 통합허브가 성장할 것이다. 플랫폼 전쟁이 시장 점유율 '횡령' 싸움임을 CSP들이 깨닫게 됨에 따라 이러한 가격 경쟁들은 더 잦아질 것으로 전망된다. 그리고 2013년 클라우드 벤더들은 클라우드 가격 책정이 비용-수익 관리(costyield management)의 연장선에 있음도 알게 될 것이다. 핵심은 효율적 설계와 저비용 운영, 그리고 무엇보다 높은 사용률에 있다. 또한 기업들이 점점 많은 애플리케이션을 소프트웨어 형태로 구매하고 있기 때문에 애플리케이션 자체를 통합하는 문제, 애플리케이션에 대한 보안과 감사 프로세스개발 등의 문제가 제기되고 있다. 시스템 통합 서비스와 통합 허브는 이런 문제를 해결하기 위해 노력하게 될 것이다 셋째, 2013년은 하이브리드 클라우드 컴퓨팅이 급부상할 것으로 전망된다. 앞으로는 클라우드 컴퓨팅 시장에서 공급업체끼리 경쟁하는 것은 의미가 없으며 기업들은 절대 한 가지 클라우드 기술이나 공급자에 안주하지 않을 것이다. 이것은 곧 2013년에는 하이브리드 및 이종 클라우드 컴퓨팅이 각광 받을 것을 의미한다. 이러한 하이브리드 클라우드 컴퓨팅을 도입하기 위해서는 클라우드 컴퓨팅의 단점과 문제 해결을 위해 하나의 목적을 가지고 다양한 산업체들이 모여 경쟁업체이면서도 협력관계를 이루는 것이 중요하다. 넷째, 멀티 디바이스를 이용한 클라우드 사용이 폭발적으로 증가될 것으로 보인다. 1인당 여러 대의 단말 보유, 이동성 향상 요구, 4G 확산 등 모바일 시장을 중심으로 한 환경 변화로 인해 이전보다 한층 진화된 클라우드 기반의 서비스가 다양하게 등장할 것으로 예상된다. 또한 4G 시대가 본격적으로 개막되면서 데이터 및 앱을 저장하는 것뿐만 아니라 앱을 실행하는 프로세싱까지도 모두 인터넷 상의 서버에서 이루어지는 방식인 클라우드 스트리밍(Cloud Streaming)이라는 신기술이 상용화될 것으로 기대된다. 다섯째, 2013년에는 'XaaS(Everything as a Service)' 개념이 보다 확장될 것이다. 클라우드 컴퓨팅의 사용이 확산됨에 따라 하드웨어의 도입, 소프트웨어 및 데이터베이스 개발과 구축, IT 서비스 등 IT 인프라 스트럭처의 토대에 많은 변화가 생겼다. 인프라스트럭처는 더 이상 고정불변의 자산으로서가 아니라 유연성과 확장성을 강조하는 서비스로서의 특징으로 점점 부각되고 있다. 따라서 모든 IT 인프라스트럭처가 Ondemand화 서비스로 제공되는 비즈니스 모델들이 부상하고 있으며 플랫폼, 하드웨어 데이터베이스 등 모든 IT 요소를 서비스 형태로 제공하는 XaaS가 2013년 새로운 개념으로 떠오를 것으로 기대된다. 여섯번째로 스토리지를 둘러싼 가격 경쟁이 더욱 심화될 것으로 보인다. 업체들의 가격 인하는 앞으로도 계속될 것이며 사용자들에게도 큰 혜택으로 돌아갈 것이지만 사람들은 가격만으로 서비스를 선택하지 않을 것이기 때문에 가격보다는 차별화된 기능 및 서비스 전략이 필요할 것이다.
