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.

이정숙,정민철,김우식,이근철,김홍중,박찬선,이헌주,주윤정,이근종,안종석,박완,박용하,민태익 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.2

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.

This study investigated the service quality level of service industry in Kyoungju. Ten different service categories were selected for this study: hotel, restaurant, bank, taxi, local bus, express bus, airlines, hospital, private education institute, and community bureau. To test service quality, five dimensions of service were used: reliability, responsiveness, assurance, empathy and tangibles. In general, people in Kyoungju perceived the service quality of Kyongju as poor. In particular, among 10 different service industry, they evaluated the services of taxi and local bus industry as worst. Tangibles, reliability, assurance, responsiveness and empathy were listed in order of declining relative satisfaction to customers. The main reason of the poor service in Kyoungju is the management's lack of understanding the importance of service.

본 연구의 목적은 동국대학교의 교수들이 수행하고 있는 교수학습 방식을 파악하고 각 방법들의 효과성을 교수들이 어떻게 인식하고 있는지를 알아 보고자 하였으며 창의적 교수학습방법개발에 대한 교수들의 요구를 파악하여 교수학습개발센터의 프로그램개발을 위한 기초자료로 삼고자 하였다. 수업방식에 있어서 전공, 교양을 막론하고 대부분이 강의식 수업방식이 높았으며(80.9%, 86%), 발표식, 토론식이 (14%, 18.6%) 실험실습 등이 그 다음으로 나타났다. 교수들은 전공과목보다는 교양수업에서 학생들의 요구에 맞는 수업 수업방식을 고려하고 있는 반면 수업방식의 효과에 대해 53%만이 효과적이라고 보고하고 있다. 교수들도 효과적인 강의방법 등 교수법에 대해 체계적으로 학습할 필요성을 느끼고 있었다. 강의 기술(교수방법)과 토론 중심 수업 방법에 대한 워크샵에 대한 요구가 가장 높게 나타났고 발표수업과 프로젝트수업 방법 등 강의식 수업 이외의 다른 수업방식에 대한 워크샵 요구도가 높았다. 그 외에 학교의 지원에 대해서는 첨단 수업 기자재 활용을 위한 보조자(조교)에 대한 요구도가 가장 높고 강의 운영을 위한 보조금, 개인별 상담 지원 순으로 요구도가 높게 나타났다. The purpose of this study was to comprehend the methods of teaching and learning carried out by the teachers of Dongguk University, and to find out how the professors found those methods effective. This research was also used to serve as a basis for the development of a more creative teaching-learning system to enhance better programs for the Professor Teaching-Learning Development Center. In teaching methods, regardless of classes for majors or for cultural enrichment, most of the courses were in the form of lectures (80.9%, 86%) followed by research and discussion (14%, 18.6%), with experiment and practical training coming in third. Although professors tend to choose a more student-oriented class method in distribution courses more than in major courses, it was reported that only 53% of the faculty claimed this class method to be effective. The faculty felt the need for professors to have more constructive learning in incorporating more effective teaching methods. The demand for professor workshops on teaching skills (teaching methods) and discussion oriented classes proved to be high, as well as the need for workshops on teaching methods other than lectures, such as research courses and project oriented class methods. Regarding other demands for university support, the demand for an assistant (assistant teacher) to help with the new technology equipment was the highest, followed by subsidies for course management and support in individual counseling.

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.

돼지 아데노바이러스(PAV-3). 6618주의 EIB region이 包含되어 있는 map unit 4.0에서 9.7까지의 유전자에 대한 1,984 bp의 염기서열을 決定하였으며, 이 結果를 알려진 여러 아데노바이러스 유전자와 비교하여 다음과 같은 결과를 얻었다. 1. PAV-3의 EIB유전자는 10개의 ORF로 구성되어 있으며, 그 중 아데노바이러스의 단백질과 유사성이 있는 것은 ORF1, ORF2 및 ORF3이었다. ORF1은 Ad41의 19kd 와 BAV-2에서의 EIB ORF2에서의 아미노산의 一致率은 각각 32%와 31%이었다. 2. ORF2는 Ad2 55kd protein과 tupaia adenovirus 44kd protein가 각각 34%로 아미노산 一致率이 가장 높았으며, Ad41의 52kd protein. BAV-3의 EIB ORF3에서도 33%의 一致率을 보였다. 3. ORF1은 61-666 uncleotide (606 bp), ORF 2에서는 429-1,850 uncleotide (1,422 bp)의 부위로 각각 202, 474 a.a로 構成되었으며, 예상되는 분자량은 20 kd와 52 kd이었다. 4. ORF3는 hexon-associated pIX유전자로 추정되며 내부에 1개의 polyadenylation signal(ATAAA)이 1938-1942 uncleotide에 위치하였으며, 이 부위는 TATA box (1937-1942 uncleotide)와 중복되어 존재하였다. Porcine adenovirus type 3 (PAV-3) does not cause severe infection in pigs. Adenovirus has been suggestive of live vaccine vector carrying foreign gene. One of insertion regions is delayed early (EIB) region. However, EIB region of PAV-3 has not been molecularly characterized to date. Nucleotide sequence of EIB of PAV-3 was determined. The EIB region was composed of 1,984 bp and located between 4.0 and 9.7 map units. Three potential open reading frames(ORFs) with low level of homology to other adenoviruses and a polyadenylation signal were identified in the rightward direction of genome. The nucleotide and the predicted amino acid sequences of EIB were compared to those of human and animal adenoviruses. One of the three potential ORFs. ORF1 encoded a polypeptide homologous to bovine adenovirus type 2(BAV-2) ORF2 and human adenovirus type 41(Ad41) 19 kd protein. ORF2 encoded a polypeptide homologous to human adenovirus type 2(Ad2) 55 kd protein, bovine adenovirus type 3(BAV-3) ORF3 and porcine adenovirus type 4(PAV-4) ORF2. The predicted protein of ORF1 had homology to those of Ad41 and BAV-2 with 32 and 31% respectively, whereas the deduced protein of ORF2 had homology to those of Ad2. BAV-3 and PAV-4 with 34, 33 and 29%, respectively.

최적화 기법을 이용한 동작 재활용

朴智憲,金宗煥 弘益大學校 科學技術硏究所 2001 科學技術硏究論文集 Vol.12 No.-

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.

In this study gene encoding structural proteins of a CPV isolate was cloned and saquenced to elucidate the molecular genetical properties of the canine parvoviruses isolated from the field. Six recombinant plasmids of pEP3, p1471, p2070, pEP069, pEP338 and p14711p were constructed from the map positions 22 to 98 of RF DNA to clone the VP1 and VP2 genes of CPV-V20. Sequentialy the gene comprising 3780 nucleotides were sequenced by dideoxy chain termination method. When nucleotide sequence of gene encoding the structural proteins of CPV-V20 was compared with those of other strains, CPV-N, CPV-d and CPV-780929 published previously. DNA homologies to CPV-V20 were 99.87% with CPV-NM, 99.73% with CPV-d, 96.85% with CPV-780929 AND 98.4% with FPLV-Carl, respectively. The DNA sequence data of CPV-V20 showed seven point mutations and also deletion of 135 nucleotides from the nucleotide position 4745 to 4879 located in the 3-noncoding region of CPV-N.
