This work aimed to analyze current status of by-products generation and industrial symbiosis network in Gyeongsangbuk-do, South Korea. Manufacturing sector of the province mainly consists of electronics, machinery, steel, metal-working industries. Gumi and Pohang have the 1st and 2nd largest worker population in the manufacturing sector. 21,950.7 ton/d of waste is generated from the industries in 2011, of which 82.2% is recycled. The industrial waste, which is not recycled, is mainly composed of sludge cake from domestic wastewater treatment plants, waste plastic, incinerator ash, and slag. Pohang is the largest generating city of both total and the non-recycled industrial waste in the province, and most of the waste is from Pohang steel industrial park. Symbiosis map in Pohang steel industrial park shows that most of the current material symbiosis in the industrial park is for waste refractories and slag.

표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

박종한,이종훈,최순옥 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.2

60세 이상 노인들에서 CIDI가 치매와 비치매를 얼마나 잘 예측할 수 있는가를 알아보기 위해서 시행되었다. 방법: 어느 대학병원 정신과 환자들 중에서 DSM-IV상 치매 환자 86명과 60세 이상의 비치매 환자 129명이었다. 여러 변수들 중에서 교정 연령(실제 연령 -59), 교육 구간(무학,초등 교육, 중등교육, 고등교육), 그리고 CIDI 총점을 독립 변수로 하고, 치매 유무를 종속 변수로 하여 로지스틱 회귀 분석을 실시하였다. 결과: -2 log likelihood는 상수만 포함된 경우에는 289.395이었고, 교정 연령, 교육 구간, CIDI 성적 등의 독립 변수가 포함되면 102.773이었다(χ²=186.622, df=3, p=0.000), 적합도 통계는 156.798(χ²=6.5843,df=8, p=0.5821)이었다. 전박적 분류 일치율은 90.2%이었다. 세 독립 변수들의 통계값을 이용하여 로지스틱 회귀 방적식 y=7.5752 + 0.0940 * X₁+0.9820 * X₂-0.1811 * X₃(y=ln[π/(1-π)], X₁ :교정 연령, X₂: 교육 구간 X₃: CIDI 총점, π : 치매일 확률, 0.50 이상이면 치매, 미만이면 비치매)을 만들 수 있었다. 진단 예측에 영향을 끼치는 변수들 즉, 교정 연령, 교육 구간, 그리고 CIDI 총점의 □(95% C.I)는 각각 1.0985(1.0107 - 1.1940), 2.6699(1.4134 - 5.0436), 0.8344(0.7898- 0.8815)이었다. 결론: 회기분석 결과 CDIA는 치매 진단의 예측에 매우 유용한 인지기능 평가 도구임이 확인되었다. Objective: This study aimed at investigating the diagnostic predictability of Cognitive Impairment Diagnosing Instrument(CIDI) in diagnosing dementia of elderly people aged 60 years or more. Method: The subjects were 129 patients with other mental diseases than dementia whose ages were more than 60 years and 86 patients with dementia. Psychiatric diagnoses were made by according to the DSM-IV criteria. Converted age(chronological age minus 59) was employed for the statistical reason. The length of education was classified into 4 intervals : 1 for less than one year schooling, 2 for grade schooling, 3 for junior or senior high schooling and 4 for college or more schooling and each number espresses ordinal scale. The converted age, length of education expressed by one of 4 interval scores, and total CIDI score were independent variables while the diagnosis(dementia vs nondementia) was dependent variable in the logistic regression analysis. Results: -2 log likelihood was 102.773 when the lenght of education, converted age and total CIDI score were included while it was 289.395 when only the constant was included(χ²= 186.622, df=3, p=0.000). The goodness-of-fit statistic was 156.798(χ²=6.5843, df=8, p=0.5821), and the overall conocordance of diagnostic classification was 90.2%. The logistic regression equation for the diagnosis of dementia was generated as follows : y=7.5752 + 0.0940 * X₁+0.9820*X₂-0.1811*X₃(y=1n[π/(1-π)], X₁ : converted age, X₂: education intervals, X₃:total CIDI score, π : possibility of dementia, ≥0.50 indicating dementia and < 0.50 ndicating nondementia). The ebs(95% C.I.) for the converted age, education interval and total CIDI score were 1.0985(1.0107 - 1.1940), 2.6699(1.4134 - 5.0436), 0.8344(0.7898 - 0.8815), respectively. Conclusions: The CIDI could be considered as a useful diagnostic tool for dementia using the logistic regression analysis.

This paper presents a new method for quaternion based articulated rigid body animation by reusing an existing motion data. We provide displacement, first and second order differential kinematics of quaternion based articulated rigid bodies. Quaternion allows us to interpolate properly three degree-of-freedom joint orientation rather than chunks of one degree-of-freedom joint angle. Based on the quaternion kinematics of two different bodies, we assign a kinematic constraint equations for a cost function which aims to mimic original motion as close as possible. The approach taken in this paper is different from previous researches in the sense we do not deal with any matrix inversion, which makes non-natural motion animation.

협상연구의 발전과 과제 : A Critical Review on its Developments and Challenges

박헌준,이종건 한국협상학회 2001 협상연구 Vol.7 No.1

본 연구는 지난 30여 년에 걸쳐 협상에 대한 연구가 어떻게 진행되어 왔는 지와 협상연구와 관련하여 나타나고 있는 최근의 주요 이슈들을 살펴본다. 지난 30년 동안 협상에 대한 연구는 정보화 및 세계화와 병행하여 괄목할 만한 성장을 보여왔다. 협상연구는 1960년대와 1970년대에 사회심리학 영역 내에서 활발한 분야였으며, 1980년대와 1990년대에는 의사결정자로서의 협상자에 대한 연구가 폭발적으로 이루어졌다. 1990년대 말에는 협상의 행위적 의사결정의 패러다임에 대한 명백한 비판과 더불어 다시 협상과정에 대한 사회학적 관점에 대한 요구가 크게 증가하였다. 또한, 인터넷 및 디지털 기술의 발달에 따른 정보화와 협상의 문제 그리고 세계화에 따른 문화간 협상의 문제 등이 깊이 있게 다뤄지고 있다. 우리나라는 1997년 말 이후 심각한 경제위기로 인한 국제통화기금의 관리체제에 직면하게 되면서외국 금융기관과의 외채협상을 필두로 대기업의 매각협상 등 국내외의 많은 협상과제를 안게 되었고, 앞으로 해결해야할 협상현안이 산적해 있다. 따라서, 급변하는 국내외 환경 속에서 경제발전을 지속시키고 나아가 국가경쟁력을 강화시키기 위해서는 정보화와 세계화에 걸맞는 협상능력의 제고가 절실하게 요구된다. This paper traces a short history of the study of negotiation for the past 30 years and reviews recent major issues with negotiations. The past 30 years have seen dramatic shifts in the study of negotiation in parallel with the development of Information Technology(IT) and globalization. The study of negotiation was an active field within the domain of social psychology in the 1960s and 1970s. The 1980s and 1990s have witnessed an explosion of research on the negotiator as decision maker. But the late 1990s brought many calls to reintroduce the social aspects of the negotiation process-with an explicit criticism of the behavioral decision paradigm of negotiation as overly restrictive. We explore emerging issues such as negotiation via technology and cross-cultural negotiation that resulted from the development of Internet and digital technology. Since Koreans have accepted the conditions of the bail-out from the IMF(International Monetary Fund), they have faced a lot of issues, such as foreign loans, big companies' M&A, and so on, to be solved through negotiation. To continue our economic growth and strengthen our international competitiveness, negotiators must know how to negotiate via technology but also understand the cross-cultural issues in negotiation.

The purpose of this study was to measure the changes of regional cerebral blood flow(rCBF) and blood pressure(BP) in rats, following the intravenous injection of Nelumbo nucifera water extract. The measurement was continually monitored by laser-doppler flowmeter and pressure transducer in anesthetized adult Sprague-Dawley rats for about 2 to 2 and half hours through the data acquisition system composed of MacLab and Macintosh computer, The results of this experiment were as follows. Nelumbo nucifera significantly increased the changes of rCBF in rats. The rCBF of Nelumbo nucifera was not changed by pretreated propranolol, atropine, L-NNA and indomethacin. But the rCBF of Nelumbo nucifera was decreased by pretreated methylene blue. Nelumbo nucifera decreased the BP significantly, The BP of Nelumbo nucifera was not changed by pretreated propranolol, atropine, L-NNA and indomethacin. But the BP of Nelumbo nucifera was decreased by pretreated methylene blue. These results indicated that Nelumbo nucifera might increase the rCBF and decrease the BP which related to guanylyl cyclase activity.

Acute myocarditis complicating coronary vasospasm after smallpox vaccination is very rare complication that can be generally developed within less than 30 days after vaccination. Clinically and biochemically, this disorder is often mimic and highly suggestive of acute myocardial infarction. We report 21 years old man that had a history of a smallpox vaccination 3 weeks ago and prodromal symptoms(fever, malaise etc) a few days ago. hIe visited to our hospital because of abrupt onset of severe substernal chest pain, dyspnea and diaphoresis. At admission, electrocardiography was ST elevation in lead Ⅰ, aVL, V4, V5, and V6. The CK-MB level was 68 U/L, LDH level was 760 U/L, Troponin-Ⅰ was 24.64 ng/㎖, and Troponin-T was positive. 2D-echocardiograpy was normal left ventricular function, Clinically we presumed this disorder as acute myocardial infarction and we promptly performed the coronary angiography and revealed focal spasm in distal left coronary artery territory without critical stenosis in both coronary arteries. We diagnosed this disorder as coronary vasospam complicating acute myocarditis that is different with acute myocardial infarction, and we prescribed nitroglycerin and nifedipine. After discharge, he is now well without any symptoms and has been following up monthly at our outward department for 6 months.
