The spotted seal (Phoca largha) in the Yellow Sea has declined due to poaching and habitat destruction. To aid conservation efforts, Argos satellite tracking were used to monitor the movements of a free ranging spotted seal around Baengnyeongdo Island. The satellite-transmitting tag successfully attached to the seal provided 1,556 location data collected during 107 days. The seal mostly moved between two haul-out sites, Yeonbong Rock and Mulbeom Rock. From October 6th to December 12th, the seal stayed within a 7 km radius of Yeonbong Rock. However, as the signal was lost, it was not possible to identify when the seal started to migrate from Baengnyeongdo Island to winter breeding area. This study provide understanding into the habitat preferences and movement patterns of spotted seals around Baengnyeongdo Island, contributing to the conservation and management of this species. Further research with more individuals and different age groups is essential to understand their habitat preference and develop effective conservation measures for the spotted seal population in the Yellow Sea.

Conservation measures for excavated and surveyed buried cultural heritages are decided by the administrator of the Cultural Heritage Administration according to their scientific and historic values. However, management, preservation, and use after relocation and restoration remain unsystematic. An issue regarding preservation plan and use has arisen due to the damage of preserved heritages and protective facilities. Thus, this study aims to suggest a plan for preservation and use by investigating the present conditions of the preserved heritages in the Chungbuk area. Results showed that there are 43 preserved heritages in Chungbuk, most of which remain unmanaged systematically irrespective of the managing body. Remainder and protective facilities have been damaged due to wrong preservation treatments and selection of materials, and a problem also rises in terms of utilization, such as exhibition, education, and experience of preserved heritages. To improve such problems, a medium and long-term plan shall be established for the improvement of legal and institutional instruments, securing of budget, increase in professional manpower, development of standardization and inspection manuals, continuous monitoring, preventive preservation, research on relocation methods and materials, listing, and the creation of specialized museum and complex theme park. If a preservation plan suited to the investigated heritages can be developed, heritages can be preserved and managed more systematically and scientifically, and be used for various purposes like education, exhibition, public relations, etc.

The purpose of this study is a suggestion that it is a way for conservation and management the Namgye Seowon's heritage value based on its landscape visibility and land use; Namgye Seowon is a world heritage registration object. To do this, We had done a field investigation and a literature examination. The investigations are as following; first, setting protection zone through a comprehensive approach beyond uniform cultural properties protection zone is to note current intellectual situations as well as the place related to the locational characteristics and figures of Namgye Seowon. It's to set fore seeable section of landscape by analyzing visibility focusing through on Pungyeongnu, and it consider with protection zone and the present condition of land use. Especially, external view of landscape in Namgye Seowon is visualized with Baekam-san in the distance view of it and Cheonhwang-bong in Daebong-san and nearby large soundproof walls and the towers acts as an impediment factor to the view of landscape. In addition, to recover the original view of landscape of the Namgye Seowon, reckless plans focusing the authenticity of the world heritage should be limited and in case of the vegetation landscape, restoration and maintenance will be made through historical research literature. Through this study, researches on Namgye Seowon and several seowons will be done actively and its aims are to become the framework of landscape conservation and management measures to meet world heritage criteria.

By delivering effective, in-situ conservation of biodiversity, OECMs can contribute to sustaining existing biodiversity values and improving biodiversity conservation outcomes. In this study, for the reporting of OECMs required by Kunming-Montreal Global Biodiversity Framework, the site-level assessment of the Korea National Arboretum and Buffer Zones were conducted using the assessment tool of IUCN. The site-level assessment was carried out in three steps(step 1: screening, step 2 : consent for full assessment, step 3 : the full assessment). It was found that the criteria were satisfied except for the consent for full assessment, sustainability of governance and management arrangements, and the equity of governance and management. Although the governing authority, rights-holders or any other stakeholders could be identified, the step of acknowledging and agreeing to the full OECM assessment was not possible because the governance was not established. As a result of the assessment of equitable governance and management in the aspect of recognition, procedure, and distribution based on criterion(the equity of governance and management), it is judged that more specific measures are needed in the aspect of recognition. And in the aspect of procedure, there is no legal basis for participation in governance and collection of opinions, so it is judged that there is a limit to listening and reflecting the opinions of stakeholders. In the aspect of distribution, it is necessary to further confirm whether it provides direct benefits to rights-holders such as landowners in the region. And it is necessary to prepare specific criteria to assess the important biodiversity values. Therefore, in order to promote OECM reporting in the future, it is necessary to conduct detailed research on various types of governance establishment and operation plans that can establish the basis for recognizing and agreeing to OECM assessment, specific criteria and reasonable measures to judge equity, and important biodiversity value.

Because the hospital building operates 24 hours a day, 365 days a year for treatment and restoration of patients, it has a different pattern of energy use than that of ordinary buildings. Hospitals contribute to energy consumption and have a negative environmental impact. This study aims to find how meaningful energy performance, reflecting good energy management and ECMs, can be operated for hospital buildings, a category encompassing complex buildings with different systems and large differences between them. In this study, we proposed the energy diagnosis & evaluation method and energy management process to verify energy saving through operation data based on system & facility characteristics, operation pattern and energy consumption characteristics of hospital building. Energy consumption structures were surveyed throughout 4 reference hospital in Seoul, Korea. Findings confirm that different hospital departments have hugely different energy-demand profiles. Energy efficiency and energy saving potentials are presented. The energy performance analysis can be applied to a wide range of problems in energy-system operation.

For studying this project, we selected a 2-storied detached house as a sample which was constructed in July 1976, the last year of the 3rd 5-years economic and social development plan and also the middle year between the years of the 1st oil crisis and the 2nd oil crisis, located In Gayang-dong, Daejeon City. The contents and scope of this project was to produce retrofit measures by theoretically analyzing the building energy use between both of pre-retrofit and post-retrofit conditions of this sample house, and to compare and analyze the predicated data with experimented data under post - retrofit condition. It is suggested in this report that we have to develop rational and practical retrofit measures for energy conservations in existing residences.

Tumuli located in Chodang-dong in Kangreung City are sitesexcavated by the Museum of Kangreung University in 1993.Ofthese sites, a gilt bronze crown and gilt bronze sword with ring pommel with a tri-leaf ornament were excavated from the B-16tumulus. Underneath the gilt bronze crown was the gilt bronzes word with ring pommel with tri-leaf ornament, and these artifacts were treated with Polyurethane foams on the spot followed by special measures for conservation. This manuscript describes measures for conservation andanalysis with regard to the gilt bronze crown, gilt bronze sword with ring pommel with tri-leaf ornament and gilt bronze beltornaments. Bronze on the gilt bronze crown was completely corroded, therefore it was consolidated together with soil in the back of the artifact with Paraloid B72 after cleaning. Polyurethanefoams bottom was finished by applying the mixture of Epoxy resinAW106 and HV935K with soil. On the sword with ring pommel, the wooden part of the hilt was coated with Paraloid B72 (in Xylene) and the blade was consolidated with Paraloid NAD-10 30% after desalting with Sodium sesquicarbonate method. The gilt bronzebelt ornaments were treated with 3% Benzotriazole, coated with Paraloid B72 and then joined by using Cyanlacrylate. Specimens for the gilt bronze crown and gilt bronze belt ornaments were produced and gilding layers were examined under a metallographic microscope. The gilt bronze crown and the gilt bronze belt ornament maintained relatively good gilding quality with uniform gilding layers. Analysis of wood for the sheath of the sword with ring pommel revealed it to be Juglans mandshurica. Further more, analysis of constituents for a blue colored grassbead from dissolution of Polyurethane foams found it to be from the $Na_2O$-CaO-$AI_2O_3$-$SiO_2$ family.

Although the importance of good conservation of historical sites including ancient royal tombs is well aware, still not much attention has been paid for facilities to realize it. There are numerous ancient royal tombs spread in Korean peninsula which are opened and some of them are selectively on display for public access. However, the conservation measures of these sites have not been seriously investigated. Even the level of understanding of the underground environment of tombs is not satisfactory. In the present study, we focus on the dehumidification loads to maintain appropriate conservation conditions in terms of temperature and humidity. Two experimental tombs different in size were built in KNU (Kongju National University) campus with the dimensions ($L{\times}W{\times}H$) of $1.0m{\times}2.8m{\times}1.0m\;and\;1.3m{\times}3.0m{\time}1.2m$, respectively, HVAC systems are installed to maintain a suitable condition for conservation, i.e., $22{\pm}2^{\circ}C$ in temperature and $55{\pm}5%$ in relative humidity. The condensed water are measured to estimate the dehumidification loads while the temperature and the humidity inside the tombs were maintained within the specified range.

The purpose of this study is to evaluate the differences of recognition of the actual conditions, performances, problems and issues of the Direct Payment Program for Rural Landscape Conservation(DPPRLC) between interest groups who are residents, officials and experts. In the results of this study, there were differences in awareness of DPPRLC depending on interest groups and whether the program participation. It is determined to be caused the limitations of the program that the target district farmers recognised the program as a source of income and seldom act to manage the rural landscape except cultivating "landscape crops". Therefore, the efforts will be demanded to clarify and share the goals, contents of the project. The following measures are proposed in this study for the direction of improvement of DPPRLC: First, the various efforts are needed to overcome the differences on the interest group's recognition for goals, contents, performance of the Direct Payment Program for rural landscape conservation. Second, it is needed to conduct the program based on the rural landscape plan and participant's capabilities. Third, the various programs to attract voluntary participation from residents should be implemented. Forth, it demands the entrusted implementation to professional organizations to support resident's voluntary activities of surveying rural landscape resources, planning rural landscape conservation, execution of village landscape conservation, etc. Fifth, the various programs to strengthen participant's capabilities should be implemented.

All excavated "buried cultural properties" are supervised by the Cultural Heritage Administration that decides whether to conserve them or not, depending on the necessity for conservation. Currently, there is no legal regulation concerning the administration of relics (including artifacts) and remains (including archaeological sites) that are relocated and restored based on such conservation decisions. Thus, administration of these cultural properties is inadequate. Under these circumstances, this paper recommends the current state of conservation and conservation methods for buried cultural properties excavated at Chungcheongnam-do thus far. Conservation of buried cultural properties excavated at Chungcheongnam-do primarily employ the "relocating and restoration" method; 23 relics and 46 remains employed relocation after dismantling and soil layer transcription method. Moreover, 27 remains were relocated after dismantling and 14 remains employed the transcription method. In terms of area, Buyeo-gun and Gongju-si had 12 relics accounting for about 50%, while according to the period, Baekjae period had 16 relics, accounting for about 70%. In terms of conservation facility, open-air facility had 33 relics, accounting for about 72%. Results of investigating the state of relics' management indicated that public institutions like a museum with a recognizable management system had their own work force and consequently ensured excellent conservation, whereas if there were no apparent responsible bodies, remains were subjected to considerable damage due to mismanagement. Therefore, this problem can be resolved by identifying a recognizable management body as well as ensuring periodical management and supervision. The excavated buried cultural properties are utilized not only for academic purposes, but also for PR or as exhibition material. Hence, this study confirms that meticulous management of buried cultural properties is currently required.
