Foot and mouth disease (FMD) is highly infectious disease of cloven-hoofed animals, particularly problematic in cattle, sheep, pigs and goats for economic reasons. Last FMD outbreak in February, 2017 caused tremendous social and economical impacts. The Korean FMD policy aims to vaccinate intact animals and euthanize and bury infected animals to prevent the disease spread. However, there was a problem that the buried livestock did not decompose after several years. Therefore, the study was purposed to investigate the effect of Corynebacterium glutamicum and Bacillus licheniformis on the degradation of buried cow carcasses and on the soil condition; such as temperature, decomposition course of carcasses, composition of amino acids in the soil around carcasses, and plant root elongation to measure soil conditions. As a result, the composition of amino acids in the soil treated with C. glutamicum and B. licheniformis was generally higher than those in the untreated soil. Plant roots in soil treated with C. glutamicum and B. licheniformis grew longer than in non-treated soil. The results suggested that the toxic effect on a grave land buried with FMD infected livestock is reduced when treated with C. glutamicum and B. licheniformis in regard of odor reduction, promoted decaying process, and soil fertilization.

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.

To ameliorate a long-standing, persistent housing shortage in Korea, large-scale massive housing production has been an imperative, and the extensive growth highly values development and consumption. The state's priority for the quantitative growth of housing stock has proved to be successful, but the state faces with economic and environmental crises in a global era. To achieve the qualitative growth, the previous administration pronounced a green growth policy from the inception, and a series of strategic measures under a holistic plan have been taken widely and vigorously. As part of the strategies, the green home project was undertaken, and simultaneously the movement of green living led by the governance has been activated. However, little attention to the grassroots effort was paid and the efficacy hasn't been adequately addressed. This study examines the factors affecting green living of residents in multifamily housing. Based on public guidelines to green living, 106 specific items were drawn out and largely categorized into 6 areas (water, waste, transportation, air quality, consumption, and energy), and the questionnaire was constructed using them. Of 750 survey forms mailed out, 161 responses were returned and the collected data were used for statistical analysis. The findings indicated that varying degrees of green living was well practiced, the state-led green home project was relatively well recognized, and the green growth policy was strongly supported. Also the respondents' attitude toward green living were more associated with demographic variables than housing characteristics, and familiarity with green home project was related to attitudes toward green living. Since the on-going approach to green living has focused on simple and economical ways, it has proved to be effective but progressive strategies to make living greener are necessarily developed.

The district of Ganghwa-gun in the western coast (Seohae) of the Korea is consisted of several islands, Ganghwa-do, Seokmo-do, Gyodong-do, Jumun-do, Boreum-do, Seogeom-do and Donggeom-do. Since several islands of them were connected to mainland of Korea by bridges, the islands attract a lot of tourists from Seoul, Incheon and Gyeonggi-do areas. Construction of new roads, pensions, resort areas and restaurants provided economical benefits to local residents while natural vegetation of these islands has deteriorated continuously. Before biodiversity of vascular plants in these regions is damaged seriously by human impacts, it is needed to conserve original vegetation of the islands for restoration and monitoring in the future. Therefore, the primary purpose of the study is to clarify the flora of Donggeom-do, belonging to Ganghwa-gun. From the 15 times of field trips to the island, we have collected a number of vascular plants, 512 taxa in total, including 110 families, 329 genera, 449 species, six subspecies, 52 varieties, four forms and one hybrid. Of 512 taxa investigated, we have identified 12 taxa to be endemic to Korea. Six taxa were endangered or rare species which were designated by the Ministry of Environment and Korea Forest Service, respectively. 25 taxa were recognized as floristic regional indicator species designated specially by the Ministry of Environment. Seven species have shown their northern or southern distributional limit ranges, and 29 taxa were recognized as halophytes. The naturalized plants were identified as 55 taxa, and their naturalization ratio was 10.7%.

The effluent limitations for individual industry based on the best available technology economically achievable (BAT) have been required to achieve effective regulation. BAT assessment criteria that are suitable for the circumstances of Korean industry were developed in the previous study. The criteria were applied to determine the BAT for leather tanning and finishing industry. For the evaluation BAT, a subcategorization for the industry considering wastewater characteristics, source equipments, raw material and so on should be suggested. Three subcategories: A) Unharing, Chrome Tan, Retan-Wet Finish, B) Chrome Tan, Retan-Wet Finish, and C) Furskins were proposed in this study. Wastewater discharged from the each category contains high concentration of COD, chrome, nitrogen and sulfide. In particular, the concentration of nitrogen from the subcategory A is significantly greater. Twenty sites were surveyed and wastewater qualities were analyzed. Therefore, six different technologies were applied to the subcategory A for the end-of-pipe treatment technology, and a technology was used in the subcategory B and C, respectively. The technology candidates were evaluated in terms of environmental impacts, economically achievability, treatment performance and economical reasonability. As the result, the technology options for each subcategories: A) primary chemical precipitation + modified Ludzack-Ettinger process (MLE) + secondary chemical precipitation, B) chemical precipitation + typical activated-sludge process + Fenton oxidation, C) chemical precipitation + typical activated-sludge process + batch Fenton oxidation or batch activated carbon treatment were selected as the BAT, respectively.

Backgrounds: With the globalization of drug development, multi-regional clinical trials (MRCTs) have emerged to facilitate rapid availability of medicines to patients worldwide. The present study aimed to has explored attitudes and perceptions towards adopting the Korean MRCT guideline. Methods: An online survey, consisting of 16 questions, classified into two subjects, was administered to stakeholders in Korea. Most quantitative components were measured using the Likert scales. A content analysis of the qualitative components was carried out to identify the keywords in open-ended responses. Results: A total of 94 survey responses were analyzed: 51 participants from pharmaceutical companies, 11 from clinical research organizations, and 21 from clinical trial centers. The content of the guideline was rated as appropriate for clarity, acceptability, and applicability (96.8, 96.8, and 93.6%, respectively). The local environmental impact of the systemic/political, academic/technical, and industrial/economical aspects of the guideline was rated as appropriate at 95.7, 97.9, and 91.5%, respectively. The suggested adoption period was 1~2 years (40, 42.6%). The concept and individuals' domestic circumstances were the key problems affecting the clarity, applicability, and local environmental impact of the guideline. Conclusion: The Korean MRCT guideline was well-developed. Their overall impact on the local environmental impact of MRCTs in Korea was expected to be beneficial, but methods are needed to minimize the negative impacts. The findings of this study can inform the priorities for the future adoption of the guideline in Korea.

One of the major problems in fish production is that parasite-induced episodes of disease can result in significant impacts to the health of stock, mortalities and, economical losses. Seabreams are economically important fish in both the capture fishery and aquaculture sectors in Oman and represent potential species for aquaculture. The current study set out to investigate infection of polyopisthocotylean monogeneans on the gills of wild goldlined seabream, Rhabdosargus sarba, caught from Musairah region in Oman. The prevalence, mean intensity and abundance of polyopisthocotyleans on 145 fish was found to be 52.41%, 5.65 and 3.04, respectively. Three species of microcotylid parasite were isolated, one being Atrispinum acarne while the remaining two species require further study to identify them. There was no significant difference in the infection rate between host sex, however, parasite burdens were higher on larger sized fish (p<0.05) and were found to favour the first gill arch (p< 0.05). The study found that the sample of Rhabdosargus sarba landed in the waters around Musairah are heavily infected, with a predominantly immature population of microcotylids. Further work is required to better understand the potential risk each species poses to the health of its host before a decision is made on the suitability of new candidate fish species for commercial aquaculture.
