The natural ecology of our coastal zone has been well preserved because of the designation of Han-Ryea national sea park. However, recently, it is being threatened by the frequent request of district regulation of national park and relaxation of green belt, etc. And also, with the reclamation of the foreshore by the development of industrial complex and tourism resource cultivation on a large scale, development pressure for natural coast is increasing. For that reason, preservation of the ecology, organized management and investigation is needed for the islands which scenery is beautiful and rare animals and plants inhabit. And also, it is worried that major habitats of migrants are diminishing because of the district regulation of national park, relaxation of green belt zone and construction of coastal streets. Therefore. on the basis of the through environmental impact assessment, only the business which are aimed at the preservation and restoration of the natural coast should be admitted and the act of eroding must be restricted.

The resident attitude for preservation and development of amenity in Eulsuk island and its downstream area at estuary of Nakdong river in Korea were investigated by the questionnaires and the field surveys. Based on the results, the characteristics of this study area are the natural ecological preservation area, natural environmental preservation area and curtural assets for migratory birds. And there are a estuary bank, a Dadae beach and a Molundae park. Special amenities are (1) the light (sunrise, sunset etc), (2) the water(river, sea etc.), (3) the air(fresh wind, beautiful sound etc.), (4) the land space(beautiful view, recreation field, reed area, pine forest etc.) and (5) the stream(dancing of migratory birds, water flow, folk dance, history remains etc.). But at present, the environmental qualities as health, aesthetics safety, amenity and culture are deteriorated by development. So the number of migratory birds are decreasing. The residents desired that in future this area be use for the recreation space, the park and the natural leaning fields etc, as well as the restoration of destroyed resources.

The rapid development of biotechnology has increased the importance of microorganisms or their genetic information. Thus, the Nagoya Protocol on access to genetic resources and the fair and equitable sharing of benefits arising from their utilization was established, and countries are working to secure industrially and academically useful bioresources to deal with the agreement. In the case of Korea, because 67% of bioresources are imported from abroad, we are required to secure domestic bioresources as well. The number of isolated foodborne illness-causing microorganisms is predicted to invrease based on the incresing number of outbreaks of foodborne illness each year. Consequently, appropriate long-term preservation methods are necessary to secure the isolated microorganisms for the purpose of research and resourcification. Therefore, the long-term preservation methods for bacteria, fungi, viruses, and protozoa were investigated in this study, from domestic and international bioresource banks, and the functions of the cryoprotectants were reviewed and discussed. This review should be informative in the preservation of microorganisms and contribute to the development of biotechnology.

Fish is an extremely perishable food product which requires proper handling soon after harvest. The present study was aimed at assessing post-harvest fish losses and preservation practices in Siavonga district, Southern Zambia. Structured and semi-structured questionnaires were used to collect data on post-harvest fish losses and preservation practices from aquaculture producers, artisanal, and commercial fishers. All the fishers who landed on the lakeshore were interviewed, while aquaculture producers were randomly selected based on the information provided by the local department of fisheries. The results of the study revealed that all the fishers experienced post-harvest fish losses at varying degrees with those losing up to 10% of the total catch being in the majority. In contrast, aquaculture producers did not report any post-harvest fish losses. Most aquaculture producers commonly used chilling as preservation practice contrary to artisanal and commercial fishers who commonly used smoking and sun sun-drying respectively. Furthermore, fish product safety and quality control were poorly practiced in the district. Lack of cold storage facilities and fluctuating weather conditions were the major challenges impacting fish post-harvest activities. Therefore, to curb the loss of revenue due to post-harvest fish losses, we propose the introduction of new technology, self-development skills for fishing communities, and enhanced access to refrigeration facilities.

Due to an increasing amount of high rise apartment complexes and rapid city development, traditional houses and traditional housing districts have disappeared rapidly. Recognizing importance of traditional housing value, City of Seoul initiated public supports for traditional house preservation and revitalization of traditional housing district, especially Bukchon area. The purpose of this study is to examine the effects of public support for Bukchon area by investigating land value changes. Land value changes were compared among the three periods, 1) before the municipal support initiated ($1997{\sim}1999$), 2) initial period of governmental policy and support ($2000{\sim}2003$), 3) development period in which policy has activated and governmental preservation and revitalization efforts have exercised ($2004{\sim}2007$). For the comparison of land value changes, houses in other districts in City of Seoul have been selected. As a result, land value has been changed along with land value changes in other areas in Seoul. Land values of Bukchon area appeared in the middle range in Seoul area. However, the increasing rate of land value of traditional houses and traditional housing district are much higher than that of other areas. Except for economical support and legislation for preservation and revitalization of traditional housing district, there is few factors explaining the sudden increase of land values. The result indicated the positive impacts of municipal committment and policies on development and preservation projects and suggested that governmental policy and support should be practiced continuously for gradual development for the traditional housing district.

Stable cell preservation is an essential factor in the regenerative medicine for cell therapies and transplantation of biologic materials. In this study, we studied to provide more stable hypothermic preservation by protection of cell damage during the preservation at $4^{\circ}C$. The result of searching for key components that have excellent efficacy in hypothermic preservation of cells, we have identified the fact that the hypothermic preservation adding protein hydrolysates such as yeast hydrolysate is far superior to others. All protein hydrolysates that are derived from animal, plant and microbe sources have superior efficacy, especially the peptides which have molecular weights under 10 kDa have the best efficacy among the components of protein hydrolysate. The protein hydrolysates prevented the decrease of ATP level in the cells caused by hypothermic environment and they inhibited the generation of ROS. Adding antioxidants and control agents of osmotic pressure were showed to have more superior efficacy in hypothermic preservation. Finally, KUL261 solution (DMEM/F12 1 : 1 medium, yeastolate 1%, $\alpha$-tocopherol $100{\mu}M$, dextran 2.5%), the preservation solution developed in this study, showed the best efficacy in both cell viability and cell growth more than other conventional preservation solutions. In conclusion, the improved hypothermic preservation solution that contains the protein hydrolysates as a key component provide the best preservation efficacy. It provides better efficacy than other preservation solutions and will contribute to both the development of regenerative medicine and global commercialization in this therapeutic field.

The development of the Preservation Metadata: Implementation Strategies (PREMIS) aims to preserve practices beyond the limits of the Open Archival Information System (OAIS) conceptual framework; however, the examples and guidelines on connecting each metadata element to the actual data are unclear, making the design of preservation metadata in real digital archives difficult. Hence, this study investigates actual PREMIS 3.0-based preservation metadata management cases, preserves digital resources in various digital archive environments, and derives implications for the implementation and design of preservation metadata. Based on the analysis, the study proposes preservation metadata elements that can be considered when designing preservation metadata for digital archives according to PREMIS 3.0 application profile guidelines.

The "Historic city Preservative law" was legislated for the preservation of cultural properties and enacting regulations of managing the environment around them in 2004. This law was revised to "Historic city Preservative and Development law" in 2012, and specified the criteria for permissible behaviors in the preservative district. Therefore, this paper focused on the ancient capital Gyeongju and developed a comprehensive system for evaluating the value of the ancient historic district based on Analytic Hierarchy Process (AHP). Through the evaluation of the ancient historic districts, which are the pilot project districts in the "Gyeongju Ancient Capital Preservation Plan", some preferential projects were objectively proposed. As a result, according to the evaluation among 10 ancient historic districts in Gyeongju, Daereungwon got a score of 78.34, which is the highest among 7 special preservation districts. On the other side, the Gyo-dong area got a score of 76.14, the highest among 3 historic and cultural environmental districts. Finally, for the preservation and development of Gyeongju, some efficient preservation and development plans were objectively proposed for the pilot project districts in the "Gyeongju Ancient Capital Preservation Plan".

This study aims to determine (1) the inhibiting factors and solutions in the development of eco-tourism, and (2) how green entrepreneurship can be used for eco-tourism development. The increasing issue of global warming is pushing awareness of environmental preservation. This condition changes the people's paradigm in traveling from the concept of mass-tourism to the concept of eco-tourism. The development of eco-tourism has consequences for entrepreneurial activities which is known as green entrepreneurship. This study is applied research conducted in East Lombok, one of the regions in Indonesia. The sampling technique used is purposive sampling covering a total of 34 informants. Data collection methods are carried out through interviews, observation, and documentation studies. Based on the data analysis, the findings of this study show that (a) inhibiting factors of eco-tourism development are limitation of eco-tourism knowledge, lack of awareness in environmental preservation, and absence of supporting government policy; and (b) solution for eco-tourism development discovered in this research is divided into five factors i.e., condition, demand, related industry and support, strategy, government. Besides, for applying the green entrepreneurship model i.e., developing the spirit of green entrepreneurship, training in making products and services that are environmentally friendly is needed.
