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.

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.

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.

박종한,김희철,이양현,이종훈 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.3

연구목적 : 본 연구는 새로 개정된 CIDI의 신뢰도와 진단적 타당도를 평가하기 위해서 시행되었다. 방 법 : 대상은 어느 대학병원 정신과에서 진료받은 환자들 중에서 치매 환자 64명과 치매 이외의 다른 정신장애 환자들 중에서 60세 이상은 90명이었다. 그들에서 CIDI의 하위 검사 성적들간의 상관 관계, 내적일치도, 총점과 치매를 평가하는 다른 척도 성적들과의 상관 관계, 치매 진단의 민감도와 특이도를 이용한 진단 구분점의 선택, 그 구분점에서의 receiver operating characteristic 곡선을 이용한 area under curve측정 등이 시행되었다. 결 과 : CIDI하위 검사 성적들간의 Pearson 상관 계수는 0.596 내지 0.813이었고, 평균은 0.707이었고, 하위 검사 성적과 해당 하위 검사를 제외한 총점간의 상관 관계는 0.759 내지 0.890이었다. Cronbach α는 0.941이었고 어느 하위 검사를 삭제해도 별 영향을 받지 않았다. 치매 환자들에서 CIDI성적은 다른 척도를 성적과의 상관 관계가 0.5내외이었고, MMSEK총점과 CIDI 총점에서 MMSEK 총점을 뺀 점수와의 상관계수는 0.894이었다. CIDI의 area under curve는 0.933이었고 area under curve의 표준 오차는 0.021(95% CI, 0.891∼0.975)이었다. 치매를 진단을 위한 구분점은 65/66가 가장 적절할 것 같고, 이 구분점에서 민감도와 특이도는 각각 95.3%와 85.6%이었다. 그에 상응하는 MMSEK의 값들은 각각 0.930, 0.020(95% CI, 0.891∼0.969), 22/23, 89.1%와 85.6%이었다. CIDI와 MMSEK의 area under curve의 차이는 통계적으로 유의하지 않았다. CIDI의 총점은 물론 모든 하위 검사는 치매와 비치매 노인들에서 높은 수준의 감별 능력을 보여 주었다. 결 론 : CIDI는 각종 신뢰도와 각종 진단적 타당도가 만족할만한 수준이었다. 그리고 CIDI는 임상적 목적으로 인지기능을 평가할 때, MMSEK는 인지기능 장애의 유무에 대한 선별 검사 목적으로 사용되는 것이 바람직할 것이다. Objectives : This study was conducted in order to evaluate reliability and diagnostic validity of the CIDI. Methods : 64 patients with DSM-IV dementia and 90 elderly patients with other mental disorders entered this study. Inter-subtest Pearson's correlation, corrected subtest-total correlations and Cronbach's α were computed for reliability while correlation of the total scores on CIDI with the performances on other scales relating to dementia, sensitivity and specificity, area under curve using the receiver operating characteristic curve, and group comparison were used for the assessment of validity. Results : The CIDI's inter-subtest correlations ranged from 0.596 to 0.813 with a mean of 0.707. the corrected subtest-total correlations were between 0.759 and 0.890. Cronbach's α of the subtests was 0.941 and the Cronbach's αs were between 0.928 and 0.948 when any subtest was deleted. In the demented subjects, the correlation coefficients of the total CIDI score with the performances on S-SDQ, IADL, BADL, BDRS, and MMSEK were around 0.5 Area under the receiver operating curve of CIDI was 0.933 with the standard error of 0.021(95% CI, 0.891-0.975). At the CIDI cutoff point of 65/66, sensitivity and specificity were 95.3% and 85.6%, respectively. The corresponding values of MMSEK were 0.930, 0.020(95% CI, 0.891-0.969), 22/23, and 89.1% and 85.6%. The demented scored much poorer in all CIDI subtests than the nondemented mental patients, and the differences were highly significant. Conclusions : The CIDI was satisfactory regarding to reliabilities and diagnostic validities. The CIDI and MMSEK are thought to be reciprocal in assessment of cognitive function : CIDI is preferable for clinical assessment of cognitive dysfunction and MMSEK for as a screening test.

Tennis has been developed in this way. There were many progresses even in our country. However, it is difficult now to find the accurate understanding about the origin or history. Examining the currently prior researches on tennis, the mainstream is being formed by those that were discussed from the psychological, sociological, and physiological perspective. However, it is the real situation that the research materials with discussion about humanistic characteristic, or value and history are nearly nonexistent. In light of this real situation, there is a need of offering accurate data through a research on the origin and the developmental process in tennis. As a result of considering the origin and the developmental process in tennis, which is the objective of this study of having been devised by this necessity of research, the following conclusions were elicited. First, the origin of tennis is not definite. However, many scholars are having the origin as Jeu de Paume around the 12th~13th century. However, it is not what a ball game had not existed even in the former ancient times. Still, it is being accepted now as an established theory for a reason of having likely been begun from a game that the French army returned with taking it to the homeland during The Crusades and called it as Jeu de Paume. Real Tennis or Royal Tennis, which is the predecessor of lawn tennis, is recorded to have been begun from Henry Ⅶ, Ⅷ in England. It is said that Henry Ⅷ performed a game in the form of having been introduced and transformed by France at court. This was called real tennis, namely, royal tennis. Ultimately, tennis appeared as a game of the early royal family in Tudor age and was begun as a game of royal families and aristocrats. This aristocratic propensity in tennis can be considered to have led to modern society. Second, tennis was a sport of royal families and aristocrats up until the Industrial Revolution, but was developed due to a rise in the middle class and an increase in leisure time following the industrial revolution. People had leisure and social party with cricket, but thought it not to be proper for a lawn field of a garden at that time. Tennis was developed that can be performed on a lawn by the Major Wingfield in 1874. As this was popularized, a prelude of lawn tennis came to be notified. A game, which had been performed only indoors, came to be performed at the outdoor lawn court by him, thereby having come to take a main road of popularization. Third, the British cricket club was established in 1868. However, tennis came to be the center in the early days. However, owing to an extension in tennis court in 1876, the name was changed into ‘All-England Croquet and Lawn Tennis Club’ in 1877 that was the following year. As about 100 lawn tennis clubs established the British Tennis Association in 1888, it was acknowledged to be the first official organization and became an opportunity available for supplying tennis, which was formalized in many countries of the world now. With examining the origin of tennis and the evolutional process as the image of modern tennis, it comes to be dubious, too, about which the modern tennis has been developed henceforth with responding to which socio-cultural element until the present age. In addition, even a research on what was the important background that tennis in aristocratic propensity came to be spread even to general people is considered to be likely necessarily clarified through follow-up research. The outcome of this study is expected to be likely able to contribute to closely examining humanistically the relationship between history and cultural issue in the world tennis even if being a little. Furthermore, it is considered to be likely able to be utilized as basic data available for promoting humanistic understanding of modern physical education and is thought to likely contribute even to straightening error of tennis history in the academic circles of physical education history.

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.
