Nowadays, the demand of civil application of an UAV has been being increased all over the world. And many projects are going on to develop a new regulatory system for an UAV to access a national airspace. Especially, to fly UAV over the non-restricted airspace as a standard airworthiness standard, many authority funded research institutes and associations are studying regulatory environment. For the UAV to access civil airspace, the certification system of the aviation regulation have to allow this. FAA of US, CASA of Australia and European authorities are now issuing an experimental airworthiness certificate to a civil UAV. This is the first step of issuing a standard airworthiness certificate. And many people believe that civil UAV can fly over a NAS if some technical issues are resolved. In this study, I would like to present an international trends of a civil UAV regulation system, reliability trend of unmanned aerial system and would like to bring up a our regulatory environment and suggest an UAV regulatory policy.

The system of civil security service is analyzed and reviewed in order to induce it to maritime security domain. A system of civil maritime guarder who provides security service and cooperates with coast guard at sea is proposed. It is expected not only that some expecters on the field of maritime security service are built up but that the Qualities of security services are improved in considering characteristics of sea control and coast guard.

This study was performed to develop an automatic sacking device for the combine harvester which was constituted input/output signal system, controller, delivery device, shooting device, pneumatic system for shooting operation, vibration device fer sacking operation and a new developed sacking bag. A new developed automatic sacking device and new sacking bag were operated well in general. And they were possible to develop a new combine to reduce of fatigue, to improve the safety and the performance. In developed device, The optimum delivery velocity of conveyer for sacking was 5.16 mm/sec. In sacking device, sacking discharge was shown 94％ with non-vibration condition and sacking discharge was shown 99％ with vibration condition, respectively.

본 논문에서는 상용 이온성 액체를 대체하기 위해 손쉽게 구입할 수 있는 원료물질을 사용하여 이온성 액체를 실험실 규모로 제조한 후 고압 연소전 조건에서 이산화탄소의 용해도 및 재생력을 측정하기 위해 기-액 흡수평형장치를 이용하여 연구하였다. [eeim]ethyl sulfite를 제조하여 흡수실험을 실시한 결과 흡수평형압력이 25bar의 조건에서 0.72 mol $CO_2$ /mol IL의 흡수력을 보였으며, 재생성능은 탈착 전후의 흡수력 차이가 약 9%로 우수한 편이었다. 희석제를 첨가하였을 경우 흡수력은 약 38% 감소하였으나, 합성단계가 간단하며 원료물질이 저렴한 장점을 가지고 있다.

The goal of this study is to improve the competitiveness of professional librarians in society. To this end, we analyzed domestic and international LIS curriculum, determined demand from field librarians through a survey, carried out job analysis by library types, and developed an operating model for LIS curriculum by synthesizing all of these results. Finally, we suggested a course of study for civil service librarians based on this model. As a result, the six required courses for civil service librarians are: Introduction to Library and Information Science, Information Organization, Information Services (Reference and Information Services), Library Management, Information Retrieval, and Field Work. The four core courses for the civil service concentration are: Collection Development, Information Sources by Subjects, Public Library Management, and Digital Libraries. Suggested electives best suited to this career path include Using Web Resources, Information Literacy, Information Services in Culturally Diverse Communities, Library Marketing, Libraries and Cultural Programs, Reading Guidance, Library History, Small Library Management, Studies in Library Buildings, Library Cooperation, Managing Digital Collections, and Information and Communication in a Digital Age.

This paper investigates the optimum fiber reinforcement for prestressed concrete containment vessels (PCCVs) under internal pressure. To achieve this aim, steel fiber, which is the most widely used fiber type in current engineering applications, is adopted to constitute steel fiber-reinforced concrete (SFRC) to substitute the conventional concrete in the PCCV. The effects of characteristic parameters, 𝜆_sf, of the steel fiber affecting significantly the mechanical behavior of the concrete are first taken into account. Partial or complete concrete regions of the PCCV are also considered to be replaced by SFRC to balance the economy and safety. By adopting the ABAQUS software, the ultimate bearing capacity and performance for the fiber-reinforced PCCV are scientifically studied and quantified, and the recommendations for the optimum way of fiber reinforcement are presented.

Bring this analysis down to people-centered development perspective and looking through democratization in the Philippines, Thailand and Indonesia, we find similarities and differences among them related with the intensity of conflicts between development and human rights in the process of democratization in line with global transformation. Civil society in the Philippines criticized the developmental path in the Philippines which failed to implement land reform and eradication of poverty under the transition from 'patrimonial oligarchy' to democracy. In Thailand the coalition of military and the royalists had consolidated its power since Sarit military regime, which later paved the way 'hybrid oligarchy' era. Most Thai civil society organizations has regarded their developmental experience rather as 'maldevelopment' which disregarded economic and social rights. It has been especially believed by Thai localists that the stimulation of local markets and the building of autonomic community society will form the alternative economy without going against the conservative banner of nation, religion and king. Thaksin as a populist successfully took advantage of Thai localist ethos in favour of taking the seat of power. He projected himself as a modernizer focused on economic growth and cleaner politics. However Thaksin's procedural legitimacy was overthrown by counterattacking from military-royalist alliance, pretexting that Thaksin caused internal conflicts and lacked morality. Soeharto's New Order regime which can be called 'administrative oligarchy' had an antipathy towards notions of economic and social rights as well as civil and political rights. In spite of the fact that the fall of Soeharto opened the political space for democratic civil society organizations which had long struggled with development aggression and human rights abuses, there have been continuously a strong political and military reaction against human rights activists, NGOs and ethnic minorities such as Aceh and Papua. Nevertheless, Indonesian democracy is more promising than Philippine's and Thai democracy in terms of comparatively less pre-modern legacies.

본 연구는 민원을 청원과 불만표현의 두 가지 성격을 지닌 행위로 이해하고, 공공도서관에서 민원의 성격을 파악하고 그 요인을 도출하는 것을 목적으로 한다. 이를 위해 이용자와의 도서관 민원에 대한 심층면담과 선행연구를 바탕으로 설문지를 개발하여, 3개 공공도서관의 이용자를 대상으로 설문조사를 실시하고, 수거된 설문지 154부를 바탕으로 요인분석, 정준상관분석 및 회귀분석을 이용하여 통계분석을 실시하였다. 분석결과, 도서관 민원은 건의/청원과 불평행위로 구분하여 이해할 수 있었으며, 이러한 각각의 종속요인에 영향을 미치는 독립요인으로 사서전문성, 서비스편의성, 사서와의 교류 등 6개 요인을 도출하였다. 또한 각각의 종속요인에 대한 개별 독립요인의 영향을 분석함으로써 건의/청원 및 불평행위의 성격은 물론, 민원에 대한 기능적 접근뿐 아니라 구조관계적 접근의 중요성을 파악하였다. 이러한 분석 및 토의를 토대로 종속변수로서의 민원뿐 아니라 도서관 성과에 영향을 미치는 독립변수로서의 민원 및 도서관의 대처에 대한 연구의 필요성을 제시하였다.
