Trousseau's syndrome refers to an association of thrombosis with visceral malignancy. The thrombophlebitis is usually recurrent and migratory. An episode of thrombosis may precede clinical recognition of malignancy by weeks or months and in many cases, the underlying malignancy was occult. Patients with a recurrent deep venous thrombophlebitis without a known predisposing factors for hypercoagulable state deserves a consideration for underlying malignancy. We report a patients with lung cancer who initially demonstrates the clinical features of the Trousseau's syndrome.

In this paper, we have presented a high performance MULVEC (MULithreaded architecture for the VEctor Computations), as a building block of massively parallel processing systems. MULVEC comes from the synthesis of the dataflow computation model and the existing superscalar RISC microprocessor. MULVEC is composed of two processors: Vector memory control and Synchronization Processor (VSP) and Data Processor (DP). VSP manages and synchronizes datum, and DP computes datum. MULVEC have made to reduce, using the packing method and a non-blocking mode, the number of messages, the length of a queue, the number of synchronizations and context switchings, and so on. The execution time and processor utilization are evaluated for the benchmark programs on SPARC V9 (superscalar 64-bit RISC microprocessor). The result of evaluation shows that the execution time of MULVEC is less than that of uniprocessor when the number of nodes of equal to or more than three. Applications such as signal processing, image processing, and scientific computations require a lot of vector computations and they can be calculated efficiently using MULVEC.

The purpose of this study was to examine the effect of organized walking (n=9) and badminton exercise (n=9) on bone density, maximal oxygen consumption, and leg extensor intake during 6-month period of experiment with middle-aged women(48-56 years). Subjects (n=18), regularly participating to a social sport oenter, were practiced an assigned exercise 3 times a week and measurements were taken every 3-month. after the program being initiated Bone density was measured by DEXA method, VO?? by a rpogressive work load exercise, and leg extensor by isokinetic equipment. The following results were obtained from data analyses : 1. For walking group, the 6-month exercise with a regular time interval resulted in an increase in the bone density of back lumber (L1-L4). On the other hand, for badminton group, an increase was shown in the bone density of head of thigh. 2. For both groups, les extensor was significantly increased over the 6-month experimental period. 3. Subjects in walking exercise group showed an significantly increased VO?? over the experimental period while badminton group did not. These conclusions suggest that an exercise prescriptor should design an exercise program such a way that it includes both a resistance training and aerobic exercise in order to increase bone density, which has a prevention effect against aging and bone fracture, as well as to enhance strength of leg muscle and VO??.

To determine which factors influence the successful results in the patients who underwent lumbar arthrodesis with TFC(threaded fusion cage) at L34 to L5S1 intervertebral space. 20 subjects were analysed in retrospective method. Between January 1997 and April 1998, interbody fusion with TFC was undergone on 20 patients, and among them, 19 patients(95% ) were confirmed to have bone fusion at 12 months after operation. All patients were classified into group A(satisfactory results) and group B(unsatisfactory results) according to comprehensive low back questionnaires from their answer. They were checked with reference to intervertebral disc height and scoliotic, and lordotic angle with Cobb's method in the anterioposterior and lateral lumbar spine films before/after operation, and TFC diameter and length were categorized. In group A, 11 cases(55%) of "excellent" results and 5 cases(25%) of "good" results were included. In group B, 2 cases(10%) of "fair" results and 2 cases (10%) of "poor" results were included. In the lateral projection of group A and B. the mean preoperative disc height were 9.88±2.69mm and 10.45±2.39mm. Twelve months after operation, the mean disc height of group A was significantly increased to 14.11±2.14mm, but that in group B was not significantly increased only to 11.50±2.52mm. Preoperatively, the measured scoliotic and lordotic angles between L1 and S1 by Cobb's method were similar in both groups, being 4.18±3.58 and 26.75±6.64 degree in the group A, 3.50±2.65 and 33.25± 13.10 degreee in the group B. Twelve months after operation, the angles for group A were significantly improved to 0 and 48.13±11.83 degree, but in group B, not changed into 4.50±4.79 and 33.75±10.31 degree. The mean diameter and length of TFC in group A were, in each, 15.62± 1.09mm and 24.44±2.39mm but, 12.50±1.00mm and 21.00±0.00mm in those of group B. For successful results after TFC interbody fusion in the lower lumbar spine, recovery of narrow disc space, scoliosis, lordosis accompanied by solid arthrodesis were necessary. The authors propose that relatively larger-sized TFC should be profitable for those cases.

退溪 李滉의 莊屋 變遷에 관한 硏究

윤일이,조성기 부산대학교 생산기술연구소 2000 生産技術硏究所論文集 Vol.59 No.-

조선시대 선비들은 주택을 유교적 이념을 실현하는 하나의 도장으로 인식하여, 유교적 덕목을 표현 하려고 하였다. 그 중에서 사랑채는 가장을 비롯한 남자가족이 거주하며 손님을 맞이하는 곳으로 보다 유교적인 특성을 강하게 드러낸다. 이러한 사랑채의 공간은 지역, 계층, 가문, 세계관 등에 따라 차이를 가지며 지어졌고, 사랑채의 성격은 별당, 서당, 정자 등으로 주택의 내부에서 뿐만 아니라 외부로도 확대 되어 왔다. 그래서 본 연구는 조선시대 사림문화에 지대한 영향을 미친 퇴계 이황의 장옥 변천을 중심으로 한 성격형성을 살펴보아, 주택에서 분리된 공간-서당-의 특징과 사랑채와의 영향관계를 살펴본다. 16세기 사대부들의 유연하고 다양한 정신세계는 학문의 해석뿐만 아니라 건물을 짓는데서도 나타난다. 퇴계 이황의 도산서당은 한국화된 유학의 개념이 녹아든 것으로, 이후 영남지역을 중심으로 한 상류주택과 서원이 나아가는 지표가 되었다 Scholars of Chosun dynasty had made an effort to represent Confucian virtues in the dwelling in their yard, regarding them as training halls for bringing Confucian idea into realization. Among the buildings, Sarang-Chae was where the male family members including household dwells and welcome visitors. A study in the house was the building of the most distinct Confucian characteristic of all buildings. The space of Sarang-Chae was built in variations depending on factors like regions, c1asses, family tradition and a worldview. And the characteristic of Sarang-Chae in the house was extended to not only inner house complex including an annex, soedang and a pavilion(Jungja) but also to externals. Thus, this study examines characteristic formation mainly seen through the architectural variations based on the Yi Hwang's dwellings followed by look into influential relationship between Sarang-Chae and soedang a separated space from the house. Flexible and diverse mind world of the scholars in the 16th century is not only seen in the academic interpretation but also in architectures. Yi Hwang's Tosansoedang as an extract of Koreanized Confucian concept became a standard architecture of upper-class houses and sowon(educational pnvate institutes) followed in Youngnam province.

This research has an intention of studying the relation among Teachers' Sports Participation, Communication Satisfaction and School Organizational Effectiveness. The conclusion obtained from this research through these methods and processes of inquiry is : The first, Communication Satisfaction is partially changed by the form of Teachers' Sports Participation. Sports participations inside school and in-and-outside school raise the degree of organizational unity higher than sports participation outside school. Sports participation in-and-outside school raises the personal feedback higher than sports participation inside school and outside school. Sports participation in-and-outside school raises the quality of communication higher than sports participation inside school and outside school. The second, School Organizational Effectiveness is partially changed by the form of Teachers' Sports Participation. Sports participation in-and-outside school raises the degree of immersion in the organization higher than sports participation inside school and outside school. Sports participation in-and-outside school raises the organization adaptability higher than sports participation inside school. The third, Teacher's Communication Satisfaction partially influences on School Organizational Effectiveness. The higher the quality of communication and horizontal·unofficial communication, the higher the degree of immersion in the organization, organization adaptability, satisfaction on duties and entire School Organizational Effectiveness.

윤정수,박상운 濟州大學校 基礎科學硏究所 1998 基礎科學硏究 Vol.11 No.2

본 연구는 제주도 백록담 담수호에서 해안변 용천수에 이루는 고도별로 대표적인 55개 용천수에 대한 지역적 수질특성과 그 진화과정을 연구하였다. 조사지역 55개 용천수의 수질분석 결과 관음사물은 수소이온농도에서 유수암천, 장수물, 덕지샘물, 신촌큰물, 영천사, 운량천, 하원통물, 동해물, 색달생수, 안덕계곡, 화손곤물, 돗물, 화강물, 정금물은 주변 육상오염원들에 의하여 삼양제3수원, 신촌큰물, 명법사, 서느렁물, 토산물, 정금물, 곽지물, 애월하물, 고내물, 녹고물은 해수침입에 의해 오염이 진행중인 용천수들로 분류되었다. 용천수내의 전기전도도, pH, 질산성질소, 중탄산이온은 강수량이 많았을때 그 농도가 증가하였으며, 나트륨, 염소이온, 황산이온은 강수량이 많았을때 그 농도가 감소하였고, 칼륨과 마그네슘, 칼슘은 영향이 미미하였다. piper의 삼각다이어그램을 통한 조사지역 용천수의 수질특성을 보면 고산지역은 Sodium or Potassium type의 군을 형성하였으며, 저지대지역은 No dominant type과 Sulfate or Nitrate type의 군을, 해안지역은 Sodium or Potassium type과 Chloride type및 No dominant type의 복잡한 용천수군을 형성하고 있었다. 즉 제주도 용천수는 해발고도가 높은 고산 및 중산간지역에서는 bicarbonate type이 우세한 수질조성에서 저지대 및 해안지역으로 유동되면서 non-bicarbonate type형태의 수질로 변질되어가고 있었다. This study purposes to clucidate the characteristics of local water quality and the cvolutional process of the spring water have been studied with the samples from 55 selected springs, from the coast region to the Baegogdam, a caldera lake of Halla mountain in Cheju Island. Results of hydrochemical analyses in the 55 spring water show that Gwaneumsa is polluted with high hydrogen concentration, and spring waters from Yusuamchun, Jangsumul, Andukkyekok, Dotmul, Konmul, Harkangmul and Junkeummul are polluted by the pollution sources from the surface surrounding ground. Spring waters of Samyng3suwon, Meungbusa, Semurungmul, Tosanmul, Jungkeummul, Kwakgimul, Aewolharmul, Konemul and Nokgomul are also polluted from the sea water intrusion. The electrical conductivity, pH and the concentration of nitrate nitrogen and bicarbonate increase when the precipitation increases, but the concentration of sodium, the concentration of sodium, chloride and sulphate decrease when the precipitation. Quality characteristics of spring water show complicated group of spring water through piper's trilinear diagram. The high mountain region consists of groups of sodium or potassium type and bicarbonate type; the middle mountain region consists of groups of sodium or potassium type and no dominant type; the low mountain consists of groups of no dominant type and sulfate or nitrate type; the coast region consists of groups of sodium or potassium type and chloride type or no dominant type. These characteristics indicate that the spring waters are changed from bicarbonate type in the high and middle mountain regions into non-bicarbonate type in the coastal region, as the precipitated waters flow downslope.
