정신분열병 고위험군에서의 뇌영상 연구

최정석,권준수 大韓神經精神醫學會 2008 신경정신의학 Vol.47 No.5

The pafhophysiology of schizophrenia may be influenced by interaction of genetic, neurodevelopmental, environmental and/or psychological factors, which make it difficult to elucidate the etiology of the disorders through clinical phenomenology. Therefore it needs to find out endophenotypes specific to schizophrenia before onset of clinical expressions. Recently, many researchers have been concerned about subjects at high risk for schizophrenia genetically or clinically using neuroimaging techniques. In this review, we summarized neuroimaging findings performed on subjects at high risk for schizophrenia. In genetic high risk subjects, fronto-temporal abnormalities were observed, while clinical high risk subjects showed frontal abnormalities, suggestive of susceptibility markers to schizophrenia.

Effect of Oyster Shell Calcium Powder on the Quality of Restructured Pork Ham

최정석,이현진,Sang-Keun Jin,이현주,최양일 한국축산식품학회 2014 한국축산식품학회지 Vol.34 No.3

This study was conducted to evaluate the effects of oyster shell calcium powder (OSCP) as a substitute for phosphates incuring agent, on the quality of restructured pork ham. Restructured pork ham was processed under six treatment conditions:T1 (no additives), T2 (0.3% sodium tripolyphosphate), T3 (1.5% NaCl+0.5% whey protein), T4 (1.5% NaCl+0.5% wheyprotein+0.15% OSCP), T5 (1.5% NaCl+0.5% whey protein+0.3% OSCP), and T6 (1.5% NaCl+0.5% whey protein+0.5%OSCP). Addition of OSCP significantly increased the ash content and pH of restructured pork ham (p<0.05), but did not affectthe cooking loss and water holding capacity values of restructured pork ham. Addition of OSCP had no effect on Hunter aand b surface color values of restructured pork ham, but did decrease the Hunter L surface color value (p<0.05). The addi-tion of 0.5% OSCP showed significantly higher chewiness and springiness values of restructured pork ham, compared withthe addition of phosphates (p<0.05). In conclusion, the addition of OSCP combined with low NaCl and 0.5% whey proteincan be considered a viable substitute for phosphates in the curing agent, when processing restructured pork ham.

Critical reviews of Korea's EIP Projects and Suggestions for Amendments to Laws

최정석,고문현 한국비교공법학회 2012 公法學硏究 Vol.13 No.2

Industrial complexes have been regarded as important tools of industrial policy in Korea. In the process of industrial development, some industrial complexes have been blamed as major causes of environment-related problems. In response to social and environmental problems, researchers and policy makers have tried to introduce a new type of industrial complexes, which requires environmental performance and economic efficiency at the same time. As a result, ‘Eco-industrial Park(EIP)’ projects have already started up by the central government of Korea. The primary object of EIP approaches based on industrial ecology is to integrate firms' production systems and environmental management by forming networks of mutually beneficial symbiosis that mimic natural ecosystem. The government has already developed 5 EIPs and is now planning on developing more EIPs across the nation. Recently ever-first EIP Hub and Spoke strategies have been introduced in Korea, ending up in a 8 Hub EIPs. Throughout the EIP developments since the policy started, I came to know that there have been some issues and problems in the pre-existing national EIP development projects in terms of law and policy. Throughout years of experiences and researches, several important problems in recycling of resources have been exposed. Among those problems are ① Securing waste information and improving of waste database, ② Spatial restrictions of EIP Projects, ③ Lack of motivation to participate in symbiotic networks, ④ Policy banning recycling industries from locating in Industrial complexes, ⑤ Difficulties in linking to the regionally based recycling network. To solve those problems we can use several strategies. But when it comes to laws and policies in particular, revisions of these acts, ① Waste Control Act, ② Act on the Promotion of Saving and Recycling of Resources, ③ Act on the Promotion of Industrial Clusters and Plant Establishments, ④ Act on the Promotion of Change into Environmentally Friendly Industrial Structure, are crucial for the further development of the current EIP projects. Besides changes in these laws, basically a special law(for example, Act on Assistance for Industrial Symbiosis) dealing exclusively with industrial complexes can be another option in the long run. Also a regional-based recycling system needs to be introduced into Korea's EIP projects at the moment. These trials can be much of help with shrinking EIP projects and waste exchange activities leading to Korean version of EIPs and cyclical society.

Effects of Duroc Breeding Lines on Carcass Composition and Meat Quality

최정석,진상근,최양일,이재준 한국축산식품학회 2015 한국축산식품학회지 Vol.35 No.1

This study was performed to investigate the carcass composition and pork quality of Duroc breeding lines in Korea. A total of 200 Duroc pigs were used, and those were originated from four different great-grandparent (GGP) breeding stock farms (L1: N farm, L2: W farm, L3: S farm, L4: R farm). The carcasses of pigs from these farms were collected, and meat quality traits were evaluated. L1 and L2 had smaller carcass weights and thin backfat, whereas L3 and L4 had heavy carcass weights and thick backfat. L3 and L4 had higher contents of fat and protein than L1 and L2. For the meat quality characteristics, L1, L2, and L4 had higher pH values than L3. In addition, L4 had higher water holding capacity than the other lines. L4 had the highest sensory evaluation scores with regard to both juiciness and flavor. Consequently, the study results indicate that pork quality information from domestic Duroc breeding stock lines could be used to effectively improve pork quality in Korea.

해양레저선박의 지불의사금액 가치평가 연구

최정석,김화영,최경훈 한국항만경제학회 2023 韓國港灣經濟學會誌 Vol.39 No.1

This study was conducted to evaluating the willingness to pay for marine leisure ships through acontingent valuation method that can estimate the value of non-market economy. The questionnaireadopted a double-bound dichotomous choice Model and the variables for evaluating the amount ofwillingness to pay consisted of demographic variables and respondent behavior variables, and relatedinformation verified through previous studies. As a result of collecting and analyzing a totalof 309 questionnaires, the amount of willingness to pay for marine leisure ships was estimated tobe 25,510 won. In addition, significant variables affecting the amount of willingness to pay werethe experience of visiting the island, satisfaction with the introduction of new maritime transportation,and intention to revisit the island. Through this study, it can be used as a basis forevaluating the economic value of new maritime transportation by estimating the willingness to payfor marine leisure ships using the contingent valuation method. 본 연구는 비시장재의 경제적 가치를 추정할 수 있는 조건부가치측정법을 통해 해양레저선박의 지불의사금액을 추정하기 위해 수행되었다. 설문지는 이중양분형선택 방식을 채택했으며, 지불의사금액 평가를 위한 변수로는 선행연구를 통해 검증된 인구통계학적 변수, 응답자 행태 변수, 관련 정보에 관한 변수로 구성하였다. 총 309부의 설문지를 회수하여 분석한 결과 해양레저선박에 대한 지불의사금액은25,510원으로 추정되었다. 또한 지불의사금액에 영향을 미치는 유의한 변수는 섬 방문경험, 신규 해상교통수단 도입시 만족도, 섬 재방문 의사인 것으로 나타났다. 본 연구를 통해 조건부가치측정법을 활용하여 해양레저선박의 지불의사금액을 추정함으로써 보다 객관적인 신규 해상교통수단의 경제적 가치평가의 근거로 활용될 수 있을 것이다.

21세기 한국의 중국경제 연구 분석 - 주요 학술지 게재 논문을 중심으로 -

최정석,최준환 중국학연구회 2010 中國學硏究 Vol.- No.53

韩国对中国经济进行的研究有着悠久的历史。这悠久的历史是研究中国的功能变迁的主要原因,而且在历史阶段研究中国人员的功能以不同的形态发展到现在。过去文、史、哲为中心的‘中国学研究’在现在的人文科学、社会科学与自然科学等许多学科上活跃地进行研究。特别是在21世纪以后起,随着韩、中两国经济交流的活跃,韩国的中国经济学研究也变得越来越重要。1992年8月韩中建交当时只达63.7亿美元的两国贸易额在2009年达到1,409.4亿美元,足有22.1倍规模的成长。中国在2003年超越美国成为了韩国最大的出口对象国家,在2004年跃升为韩国最大的贸易国,从2007年起超过日本几乎成了最大的进口对象国家,对韩国来说是所占比重越来越大的情况。在如此的背景下,本稿将观察韩国的中国经济研究趋向。第一,观察韩国的中国研究之历史,第二,挑选五个与中国有关的学术论文集,并在从中调查出中国经济研究的所占比重以及经济学细项篇数。第三,思考一下往后韩国的中国经济研究的发展方案为中心前进的方向。
