Proximate and fatty acid compositions in muscle tissue were studied in 14 species of coastal and offshore fishes in Korea. Lipid content ranged from 0.57 to 10.5% and was higher in migratory and reef dwelling fishes than in demersal fishes. Protein content ranged from 14.4 to 20.3% and moisture content ranged from 72.4 to 81.8% in all fish samples. There was a negative correlation between lipid and moisture content in all fish samples (r= -0.90, P<0.001). The prominent fatty acids were 16:0, 22:6n-3 (docosahexaenoic acid, DHA), 18:1n-9, 20:5n-3 (eicosapentaenoic acid, EPA), 16:1n-7, 18:0 and 18:1n-7. Most demersal fishes contained considerably higher amounts of 20:4n-6 and/or 22:5n-3 compared with migratory and reef dwelling fishes. The proportion of total polyunsaturated fatty acid (PUFA), including DHA and EPA, was higher in demersal fishes (38.6-54.0%) than in migratory and reef dwelling fishes (23.5-35.2%).

Accessibility to education spaces including college lecture rooms is directly related to right to education of persons with disabilities. This study aimed to investigate barrier-free design application in large lecture rooms in colleges focusing on accessibility of persons with mobility impairments. Total 83 lecture rooms accommodating 80 or more persons in two universities in Chungcheong Province were selected as study targets. Field survey using a barrier-free design checklist was conducted between March 19, 2015, to April 3, 2015. Major findings were as follows.(1) Application rate of items in lecture room entrance section were higher than that of items in in-room passage and assigned seat sections. (2) To compare characteristics between items that showed high application rates and low application rates, application rates of items related to building structure such as level difference and width of entrance and passage were found relatively satisfactory while items that could be easily improved with low cost and efforts such as height of entrance handle, closing time of a door check, wall safety bar, anti-sliding treatment on ramp, assigned seat for persons with disabilities were not applied well. (3) Among items with low application rates, ramp needs to be adopted from planning stage as it is not easy to be added after construction completion to secure proper gradient for wheelchair users (1/12 or less). (4) When planning seats for wheelchair users, adaptable seats in diverse locations are desirable so that the users could have location choices.

본 논문은 실증분석을 통해 제천시 한방산업 지원의 실효성을 검증하고 표적집단면접(focus group interview, FGI)에 의해 한방산업의 문제점들 파악한 후 이에 대한 개선방안을 제시한다. 실효성 검증결과, 제천시 한방기업 지원정책은 매출액과 수출액을 향상시키는 데 효과성이 높은 것으로 타나났다. 그러나 제천시 한방기업 지원정책은 종업원 수 증가에는 효과성이 있었지만 높은 것으로 나타나지는 않았다. 한편, 본 연구에서 표적집단면접을 통해 파악한 제천 한방산업의 문제점은 다음과 같다. 첫째, 제천시에서 한방산업을 영위하는 기업들의 재무적 영세성과 경영자의 역량부족으로 인해 한방산업 기업들은 대부분 중소기업이나 개인사업자 수준에서 정체되어 있었다. 둘째, 온라인 판매에 관한 마케팅 활동과 온라인 유통 시스템 구축에 대한 활동이 부족한 것으로 나타났다. 셋째, 제천시의 한방기업들은 한방산업을 근본적으로 발전시킬 수 있는 연구개발 역량이 부족한 것으로 파악되었다. 넷째, 제천시의 한방기업 경영자들이 원하는 지원정책과 한방기업을 지원하는 기관의 담당자들이 생각하는 지원정책 간에 괴리가 있었다. 본 연구에서 제천시 한방산업의 문제점들을 해결하기 위해 제시한 개선방안은 다음과 같다. 첫째, 제천시에서 한방산업을 영위하는 기업들의 성장 가능성을 높이기 위해서는 한방기업 경영자들에 대한 역량강화 교육이 필요하고, 동시에 한방기업 지원 기관 담당자들에 대해서도 인식개선을 위한 교육이 필요하다고 판단된다. 둘째, 한방산업 발전을 위한 온라인 마케팅 활동과 온라인 유통망 확대를 위한 지원을 강화해야 한다. 셋째, 제천시의 한방기업들이 장기적으로 성장하고 세계로 뻗어나갈 수 있도록 한방산업에 대한 연구개발 부분에 지속적인 투자가 필요하다. 넷째, 한방산업을 활성화하기 위한 정책들을 결정할 때 실효성을 높이기 위해서 정책지원을 받는 자의니즈(needs)를 수용하여 한방기업 운영에 실질적인 도움이 될 수 있도록 경영자들의 의견을 수렴하여 조정할 필요가 있다. 즉, 제천시의 한방기업 경영자들과 한방기업을 지원하는 기관의 담당자들 간의 커뮤니케이션을 원활하게 해 줄 수 있는 커뮤니티를 활성화해야 한다. This study examines the effectiveness of supporting the oriental medicine industry in Jecheon through empirical analysis, investigates the problems of the oriental medicine industry by the focus group interview(FGI), and presents improvement measures for this. As a result of the effectiveness verification, it was found that Jecheon’s oriental medicine company support policy was highly effective in improving sales and exports. However, Jecheon’s oriental medicine company support policy was effective in increasing the number of employees, but it was not found to be high. On the other hand, the problems of the Jecheon oriental medicine industry identified through the target group interview in this study are as follows. First, most of the oriental medicine industry companies were stagnant at the level of small and medium-sized enterprises or private businesses due to the financial smallness of companies operating the oriental medicine industry in Jecheon and the lack of management capabilities. Second, it was found that there was a lack of marketing activities related to online sales and activities for establishing an online distribution system. Third, it was found that oriental medicine companies in Jecheon lacked R&D capabilities to fundamentally develop the oriental medicine industry. Fourth, there was a gap between the support policies desired by oriental medicine company managers in Jecheon and the support policies thought by those in charge of the institution supporting the oriental medicine company. The improvement measures proposed in this study to solve the problems of the oriental medicine industry in Jecheon are as follows. First, in order to increase the growth potential of companies operating the oriental medicine industry in Jecheon, it is necessary to strengthen the capacity of oriental medicine company managers, and at the same time, education to improve awareness of those in charge of oriental medicine support organizations is also necessary. Second, it is necessary to strengthen online marketing activities for the development of the oriental medicine industry and support for expanding the online distribution network. Third, continuous investment is needed in the R&D sector of the oriental medicine industry so that oriental medicine companies in Jecheon can grow in the long term and expand to the world. Fourth, in order to increase the effectiveness of policies to revitalize the oriental medicine industry, it is necessary to collect and adjust the opinions of managers to accept the needs of those who receive policy support and to be of practical help in the operation of oriental medicine companies. In other words, it is necessary to revitalize a community that can facilitate communication between managers of oriental medicine companies in Jecheon and those in charge of institutions supporting oriental medicine companies.

The proximate and fatty acid compositions of the edible portion of three species of cultured freshwater fish (common eel Anguilla japonica, rainbow trout Onchorhynchus mykiss, and Israeli carp Cyprinus carpio) were compared between imports from China and domestically produced specimens. The lipid contents of cultured common eel and rainbow trout were rich in imported f ishes (20.4 and 12.2%, respectively) compared with those in domestic ones (16.0 and 8.01%, respectively), while those of Israeli carp were rich only in the domestically produced specimens (8.06 and 3.07%, respectively). There was a negative correlation between the lipid and moisture contents in all f ish samples (r =-0.86). The protein contents ranged from 16.6 to 21.3% in domestic f ishes and 15.3 to 19.1% in imported ones. The most prominent fatty acids in the f ishes were: saturated fatty acids, 16:0, 18:0 and 14:0; monounsaturated fatty acids, 18:1n-9, 16:1n-7 and 18:1n-7; and polyunsaturated fatty acids (PUFA), 18:2n-6, 22:6n-3 (docosahexaenoic acid, DHA), and 20:5n-3 (eicosapentaenoic acid, EPA). The percentage of n-3 PUFA (e.g., DHA, 22:5n-3, EPA, and 18:3n-3) was higher in domestic common eel and Israeli carp than in imported ones, but similar in domestic and imported rainbow trout, and higher in domestic wild rainbow trout than in cultured ones. On the other hand, all of the cultured freshwater f ishes contained a relatively large amount of 18:2n-6, which is a characteristic fatty acid in cultured f ish lipids.

An antimicrobial material was purified from the acidified whole body extract of the jellyfish Nemopilema nomurai by using C18 reversed phase and cation-exchange high performance liquid chromatography (HPLC). Whole body extract and the purified compound (JAP-1) showed potent antimicrobial activities against a wide range of microorganisms including Escherichia coli D31, Bacillus subtilis, Streptococcus iniae and Candida albicans, without significant hemolytic activity. Treatment of JAP-1 with trypsin completely abolished all antibacterial activity against Bacillus subtilis, suggesting that JAP-1 is likely to be a proteinaceous antibiotic. The molecular weight of JAP-1 was determined to be 680.10 Da by MALDI-TOF mass spectroscopy.
