A self-piercing rivet(SPR) is a mechanical component for joining dissimilar materials. It is used for joining dissimilar material sheets such as aluminum alloy and steel. The self-piercing rivet directly pierces into sheets without drilling sheets beforehand unlike conventional rivets. However, the self-piercing rivet occurs buckling when piercing high strength steel. Therefore, a helical SPR which can pierce high strength steel sheet was designed. In this study, forging process was designed for manufacturing the helical SPR and simulated by using commercial FEM code DEFORM-3D. In the simulation of forging process for manufacturing rivet, process sequence, formability, forging load were investigated. The suitable forging process could be designed by comparisons of simulated results. Experimental trials have been carried out for same conditions as simulated ones. The simulated results agreed with the experimental ones. So, the analytic approach in this thesis is useful to save cost and time in the forging industry

Two dogs (case 1: 4-years-old female Dachshund, case 2: 1-years-old male maltese) were reffered with petechia. Result of blood analysis and coagulation test reveled immune-mediated thrombocytopenia in all dogs. Treatment with MMF for them, case 1 present steroid-induced hepatopathy, case 2 present anemia, so treated with Human IgG and blood transfusion. 3(case 1) or 2(case 2) months after initial treatment, clinical features were improved, and continuous monitoring is needed.

This papaer presents the design of programming language, named HAN-BASIC(HANgul BASIC), which is especially devised for the personal computer users who can't even understand English. This language gives the ability of programming with Korean language, permitting English variable names. In order to respond in real time, HAN-BASIC reserved-words is parrsed using hashing and finite automata method.

Taxonomical studies of Korean mammals have been reported by Several foreign zoologists (MORI, KISHIDA, THOMAS, KURODA). However no study has been made on the ecological investigation of Korean mammals yet. Previously Writers reported on the Order Artiodetyla in dongGuk Journal vol.6.7. This paper reports the results obtained from the study which was made ecological aspects of korean mammals Since 1950 dealing with II species of Insectivola as follow.

1. This investigation on feeding habits and ecology of 15 Species birds, Himalayan Cuckoo(Cuculus saturatus horsfieldi), Korean Great-Tit(Parus major wladiwostokensis), Black-Raped Oriole (Oriolus chinensis diffusus), Manchuriar Jungle-Crow (Corvus levaillantii japonensis), Eastern Carrion-Crow (Corvus corone orientalis), Eastern Golden-Plover (Charadrius dominicus fulvus), Korean Buzzard (Buteo buteo burmanicus), Ussurian Tree-Sparrow (Passer montanus dybowskii), Feathered-Toed scops-Owl (Otus aiso semitorgues), Chinee scope-Owl (Otus scope jstictonoctonotus) Korean Wood-Owl (Strix aluco ma), Long-Eared-Owl (Asio otus otus), Short-eared owl (Asio flammeus lfammeus), Eastern grey hero (Ardea cinerea jouyi), Plumed egret (Egretta alba modesta), carried on from 1957 to 1967, Dec.. 2. With comparative investigation on their feeding habits and ecology, these birds was divided into three groups, Agricultural birds, 9 species, which concerned with agriculture and crops, Forestry birds, concerning with forest and Fishery birds, concerning with fishery. 3. Agricultural birds, 8 species almost consumed noxious insect, various rodents as foods which injourious to crops. Forestry birds 5 species consumed too almost noxious insects for food, and with this results, all these birds belong to beneficial birds. 4. These all birds have to be protected, and be studied to seek out more effective way to protect them.

The excavation works for deep foundation in urban areas have recently increased complaints of blasting vibration and settlement of ground level. Foundation must be excavated approximately up to 24∼28m depths from the surface. The roads and subway line pass through the excavation area. The Dae-chung station is also located at the nearest distance 5∼35m fron the working site. To protect subway station and adjacient some structures from blasting and settlement, the level of ground vibration, displacements and stress were monitored and analyzed. The results can be summarized as follows : 1. An empirical particle velocity equation was obtained by test blasts at Nassan Missi 860 Officetel construction site. V=K(D/√W)^-n, where the values for n and k are estimated to be 0.371 and 1.551 respectively. From this ground vibration equation, the max, charge weight per delay time against distance from blasting point is calculated. Detailed blasting method is also presented. 2. To measure the horizontal displacement in directions in directions perpendicular to the borehole axis, 6 inclinometers installed around working sites. The displacement at the beginning was comparatively high because the installation of struts was delayed, but after its installation the values showed a stable trend. Among them, the displacement by 3 inclinometers installed on a temporary parking area showed comparatively high values, for example, the displacement measrued at hole No. IC-1 recorded the max, 57.33mm for 7 months. So, all of these data was estimated below a safe standard value 103mm. 3. Seven strain gauge meter was installed to measure value of maximum stress was-465㎏f/㎠, -338.4㎏f/㎠, 302.3㎏f/㎠ respectively. In compare to the allowable stress level of steel, they are estimated to be safe.

Background: Recently social requirement for collaborated treatment of medical practice with oriental medicine has been increasing. This study is designed to provide the guidance of role of family medicine physician in oriental medicine hospital to help the establishment of interdepartmental cooperation between western and oriental medicines. Methods: Medical records of a total 973 patients administered in Chonju Oriental Medical Hospital of Wonkwang University from January Ito June 30 were reviewed. Data including sex, age distribution, periods of administration, past history, major clinical manifestations, diagnosis, laboratory tests, medications were collected and expressed as a percentage. The classification of Diseases was made according to ICPC. Results: Of 973 patients, sex ratio was 1:1.4 with female predominance and age distribution was highest in fifties and sixties (48%). Past history was dominated in cardiovascular disease (30.1%), postoperative sequele (16.4%) and diabetes (12.2%). Chief complains were ordered in frequency as arthralgia and myalgia (42%), hemiplegia (26%), dysphagia (17%), headache (13.8%), dizziness and vertigo (11.5%). Major diagnoses were cerebrosclerosis (39.7%), HNP (21.4%), cerebral hemorrage (11.2%) and arthritis (8.79%). Diseases of the administered patients were classified as cardiovascular (50.8%), musculoskeletal (31.8%), gastrointestinal (6.2%) and nervous systems. Conclusion: The main categories of the patients who were aided by family medicine physician in oriental medicine hospital were chronic debilitating diseases including cardiovascular disease and diabetes. To establish an effective collaboration of family medicine physicians in oriental medicine hospital, the doctors needed expert skills for treatment of supportive cares of chronic degenerative diseases and their complications.
