This study was conducted to establish the appropriate facilities criteria of the Korean welfare devices center. We e-mail surveyed 194 welfare devices centers and analysed 13 blueprints of them. We established the following proper principles of facilities. First, consist type and area of room should depend on the type of welfare devices centers. Second, The flow of human and welfare devices should be simple. Third, the area calculated on the base of intent of center owner and the size of beds, wheelchairs, etc. Fourth, exhibit room facing with roadside may obtain advertising effect. Fifth, the storage and disinfecting room should use different entrance, and avoid the intersection of flow to prevent cross-contamination. Sixth, the access road to the exhibition and consulting room should be able to approach by the wheelchair. seventh, office room should be invisible to keep customer's privacy. Direct Cleaning-disinfecting type center on the premise that the maximum 165m², middle 150m², intermediate 140m², display at least Consultation, Cleaning-disinfecting room, storage (clean, contaminated), the office, equipped with a parking space. Entrust Cleaning-disinfecting type center on the premise that a maximum 134m², middle 119m², intermediate 109m² exhibited minimal activity room, consultation room, office, equipped with a parking space, collecting welfare when importing equipment warehouse (clean, pollution) have been proposed to equip up to.

The National Chuncheon Museum has carried out a conservation process in order to prevent corrosion of the seated iron Śākyamuni Buddha statue from Goreyo Dysnasty for its exhibition. Before the conservation process, the surface of the artifact showed exfoliation and the artifact was damaged from rear to legs so exhibition was impossible. Therefore a process to get rid of pollution and to reinforce and protect the artifact was carried out. Before the reinforcing process, a basic test was carried out using micro crystalline wax type with reference to foreign and domestic experiment results. As a result, as wax(in xylene) 5wt% of Dongnam petrochemical Ltd. showed no efflorescence and little change in surface color and was convenient to use, it was chosen as a reinforcing agent and used to suppress corrosion. For the restoration of damaged parts, an internal support was made and used with an epoxy resin, allowing removable restoration, thus increasing effectiveness for exhibition.

The purpose of this study was to present specific standards for landscape planning and construction applicable to landscaping areas in various historical sites. The results are as follows: First, the types of historical sites are classified according to their preservation status and processing techniques, and the classification according to their status is divided into those that have been buried underground, such as those that have been exposed to the ground, such as buildings and structures, and those that have a reputation or a record of the sites. The classification according to the wartime processing technique was classified by such techniques as closures that isolate the site, penetration that can be seen on the site, and overlays where a separate protection facility is installed on the site. Second, the principles of landscape planning for display of historical sites are divided into the items that make up the historical site, surface treatment of the sites, tree planting, and installation of facilities. If the site is not a circular space, the area separating the space by different materials between the components is required. In the event that preservation of the historical site is required, it is deemed desirable to use the soil, and to do so, the use of grasses and shrubs is effectively considered to be effective. The introduction of plants and plants should be considered according to the nature of the space. Depending on the area and nature of the monument, the facility is required to take a cautious approach by reviewing its influence on the landscape and the additional excavation of the monument. Third, the readjustment method derived as a result of looking at the landscaping principle in the historical site space was classified as conservation of status, installation of protection facilities, burial, restoration, relocation, and reproduction. Preservation of the status quo is essential for limited landscape planning and should not affect the prototype of existing relics. The protection facility shall be installed where necessary to protect the relics, and when the soil is formed, the surface treatment shall be required to remove trees that could damage the site and prevent soil and soil oil from being lost after the site. The restoration shall establish a landscaping plan according to the circular preservation based on the clues to the circle. The transfer requires a landscaping plan to create an environment similar to the outer space of an existing site and should be able to highlight the value or location of the original site. The reenactment should have a landscaping plan to revive the landscape and atmosphere of the past for the now-defunct remains. Fourth, landscaping can simultaneously satisfy the preservation of excavation sites and the increase in exhibition effects. In order to protect the traces of the past and vitalize the site of the ruins today, specific measures are required, the creation of a park for historical sites that preserve the functions and value of the relics, and the formation of a shape of linked contents can be suggested as alternatives.

Drone was first used for military purposes but as the range of use has recently expanded. It is being widely used in various industrial fields such as agriculture, service, logistics, and leisure. Lithium polymer batteries are lightweight and highly efficient, so they are mainly used as power supplies for drones. Accordingly, the need for lightweight and high energy density lithium polymer batteries has increased in order to supply stable power to drone. However, lithium polymer batteries can lead to ignition and explosion due to overcharging, short circuit, etc., so they must be used with a protective circuit installed. The protection circuit consists of a protection IC that monitors the voltage of the lithium polymer battery and a dual N-channel MOSFET that acts as a switch in case of overcharge and overdischarge. Therefore, this paper was implemented in one package form using a battery protection IC and a MOSFET semiconductor die chip serving as a switch. When implemented as a one chip package IC, at least 67% of savings compared to existing parts can be achieved.

The South Korean Defense Ministry is planning and pushing forward to conduct a cloud computing pilot project in 2012. Taking into consideration the high-level security necessary in the military as well as wartime duties, if not designed properly, this project may anticipate severe damage to national security and interest. In particular, despite the fact that vulnerability due to inter-Korean confrontation and regular security-related incidents have been triggered, unconditionally conducting a cloud computing pilot project without reviewing not only violates security regulations but also causes various security-related side effects in and outside South Korea. Therefore, this thesis found conditions for conduct of this project by suggesting duties that can apply cloud computing as well as security technology, administration, post-accident matters and conditions for legally solving cloud computing in the military.

차세대원전을 위한 새로운 운전여유도 평가체제를 정립하였다. 본 연구에서 개발된 운전여유도 평가체제는 노심감시 및 보호체제는 그대로 유지하되 부하추종운전시 운전여유도를 만족하는 운전허용범위를 P-ASI Diagram으로 나타내는 것이다. 새로운 운전여유도 평가 방법을 사용하여 Mode K 기법에 의한 차세대원전의 일일 부하추종운전에 대한 운전여유도 평가를 수행하였으며, 운전여유도를 만족하는 범위를 P-ASI Diagram으로 나타내었다. 본 연구에서 도출한 운전여유도와 ASI의 관계를 쉽게 파악할 수 있는 P-ASI Diagram이 COLSS와 병행된다면 운전유연성 증진 뿐만아니라 운전원의 입장에서도 더욱 용이한 부하추종운전을 수행할 수 있을 것으로 판단된다.

제주계통은 계통규모에 비해 전원용량이 큰 HVDC 제주연계선로와 단위기 용량이 큰 발전기들이 운전되고 있다. HVDC 2회선 동시 탈락이나, HVDC 미운전시 단위기 용량이 큰 발전기가 전력계통에서 탈락하면 제주계통 주파수는 급격히 저하되고 적절한 보호대책을 수립하지 않으면 전 계통 붕괴가 일어날 수도 있다. 본 논문은 저주파수 계전기에 의한 부하차단방식 적용시 고려하여야 할 조건과 제주계통 저주파수계전기에 의한 부하차단방식에 관해 기술하였다.
