Kimura's diseas is a distinct clinico-pathologic entity characterized by proliferation of vascular endothelial cells and lymphoid hyperplasia with florid germinal centers associated with lymphocytic, histiocytic and eosinopholic infiltration. Two cases of Kimura's disease are presented. The first was 53 year-old female patient who had a slow growing mass on right parotid area. The second case was a 25 year-old female patient with two irregular growing masses on both submandibular region. Both cases had markedly increased peripheral eosinophilia with 34% in first case and 31% in second case. The first was treated by superficial parotidectomy and the second by direct surgical excision of masses. The specimens were confirmed ad Kimura's disease on histopathologic examination and the two cases are presented with the review of literature.

The fracture toughness of elasto-plastic materials was directly affected by the size, shape of plastic zone which are great important parameter in large scale fracture mechanics. This paper is to observe the influences of the interference of notches on plastic deformation at notch tip of double notch. Specimens were tested by four point bending, and then the shape of the plastic deformation could be visualized with the technique of recrystallization. Beside, numerical method for the analysis of the plastic zone with a F.E.M. (Finite Element Method) were used. The obtained results are summarized as follows: 1) The behavior of plastic zone on double notch was different from single notch. 2) When the plastic zone was saturated at a limitation on the middle between the notches, the behavior of the plastic deformation of double notched specimen was similar to that of the single notch. 3) Maximum equivalent plastic strain was shown at the tips of both single and double notch. 4) The evaluated model of plastic zone by F.E.M. corresponded to the results of the experiment.

본 연구는 수중운동 프로그램이 뇌성마비아들의 체력에 미치는 영향을 살펴보고자 뇌성마비학생 5명에게 12주 동안 수중운동 프로그램윤 적용하여 뇌성마비학생들의 근력,근 지구력,유연성,민첩성,평형성 등의 변인들을 측정 분석한 결과 근력인 악력,근 지구력인 윗몸 일으키기,민첩성인 왕복달리기,유연성인 체전굴,평형성인 한발로 서기에 긍정적인 변화가 있었다. 이상과 같은 연구 결과를 동하여 볼 때 수중운동은 체력 요인에 긍정적인 영향을 미쳐 체력 향상 및 건강증진에 많은 도움이 될 것으로 사료된다. The purpose of this study were to evaluate the effect of aquatic exercise on body composition, pulmonary function and physical fitness. The subjects for this study were five spasticity cerebral palsy(18 - 20 years). The aquatic exercise program consisted of 11 item, and performed for 30-40mins in a bout, 3 times a week at the intensity of HRmax(40-65%) for 12 weeks. And the change of body weight, %fat, fat mass, vital capacity, hand grip, sit-ups, trunk flexion, closed eyes foot balance and shuttle-run have been measured in baseline, post 4, 8 and 12 weeks respectively. The following results were obtained from this study. Hand grip(2-4kg), sit-ups(5-8 bouts), trunk flexion (1 -4cm) and closed eyes foot balance(O.25-2.43sec) were increased after individually aquatic exercise for 12 weeks respectively. And, shuttle-run(O.37 - 0.9secl was decreased after aquatic exercise. These results suggest that aqustic exercise for 12 weeks affects on body composition, pulmonary function and physical fitness to the spasticity cerebral palsy. On the other hand, long term regular aquatic exercise programs are applicable to the spasticity cerebral palsy with abnormal movement in safety through the re-composition of exercise intensity and mode.

In the information age, computer has taken roots as indispensable education material. Thanks to the development of the Web and Internet, a lot of web- coursewares for computer have developed and used in the learning areas. As most web-coursewares, however, neglect the mode and the form needed as education materials, they don't attract the learner's attention. In spite of the computer's wide effect, it is ironic that only very few students use computers as a tutor. so, this study is to develop web-based courseware for English learning and improve the motivational attributes, with a systematic approach called the ARCS model of Keller.

임기병,오중열,정재동 慶北大學校農業科學技術硏究所 1996 慶北大農學誌 Vol.14 No.-

고추 '녹광' 품종의 플러그 육묘시 주야간 온도차 처리에 따른 생육조사 결과 초장은 주간온도와 DIF에 의해 영향을 받으며 절간장도 초장과 비슷한 경향이었다. 엽전개속도는 주로 일 평균 온도에 의해 좌우되었다. 엽장, 엽폭은 일 평균 온도가 증가함에 따라 증가 하는 것으로 나타났으며 생체중은 주야간 온도가 15℃처리구에서 가장 낮았고 일평균 온도가 증가함에 따라 증가하는 경향이었다. 생체중과는 반대로 엽록소함량은 일평균 온도가 15℃처리구에서 가장 높게 나타났으며 전체적으로는 야간온도가 증가할수록 엽록소함량이 저하되었다. 줄기직경은 DT/NT=15/15처리구에서 가장 낮았고 다른 처리구는 비슷한 경향이었다. T/R율은 DT/NT=30/15℃(+15DIF)처리구에서 가장 높게 나타나 지상부가 지하부에 비해 과번무됨을 알수 있었다. 따라서 녹광 고추의 플러그 육묘시 충실한 묘를 생산하기 위해서는 주간온도가 22.5℃, 야간온도는 15-22.5℃범위의 0DIF또는 약한 +DIF조건에서 육묘하는 것이 강건한 묘생산에 유리할 것으로 판단된다. Capsicum annuum 'Nokkwang' plug seedlings were treated with 9 different day and night temperatures to investigate on growth and differentiation in controlled environment conditions. The plant height was the most affected by day temperature and DIF and stem length was the similler results as plant height. However, Leaf unfolding rate and leaf length and width increased as average daily temperature increased. and especially fresh weight was worst at ADT was 15℃ and increased as ADT increased. In contrast with fresh weight, chlorophyll content calculated highest when ADT was 15℃, and decreased as NT increased respectively. The stem lengths were not significantly different among treatments with exception of DT/NT=15/15℃ which significantly decreased. The ultimate +DIF condition, DT/NT=30/15℃, caused high T/R ratio due to abundant top growth. It is concluded that DT is 22.5℃, caused high T/R ratio due to abundant top growth. It is concluded that DT is 22.5℃, and NT is ranged from 15℃ to 22.5℃ to be produced short, healthy plug seedlings in Capsicumannuum 'Nokkwang'.

When we consider the developmental level of children, minds-on/hands-on experiences have very important value for effective science learning. As a basis for the development of outdoor-inquiry materials, we surveyed the status of outdoor activities in the elementary school science, then analyzed the data. Data were obtained from fifty-one teachers of nineteen elementary schools. Most of them (about 80%) recognized the necessity of outdoor instruction. However, they were using the outdoor activities 1.7 times at average per school year in practice. Most of these activities were practiced within school or nearby areas including parks. The major reasons for these poor use of outdoor activities presented by respondents were the cognitive characteristics of children and the excessive amount of science content to be covered. Also, these outdoor activeities were focused only to the observations in natural environment and cognitive aspects. Several factors, such as the lack of time, appropriate outdoor sites and instructional materials, and the insufficient experiences on the outdoor activities of teacher oneself, were acknowledged. These results have implications for the development of instructional materials for both of children and teachers. In this study, we suggested the effective instructional methods at outdoor environment in relation to the characteristics of children, topics, and sites.

진행성 골화성 섬유 이형성증은 2 백만명 중에 1명 발생하는 매우 드문 유전질환이다. 저자들은 2차례의 외상후 심해진 진행성 섬유 이형성증환자에서 최근 다시 발생된 외상후 생긴 병변부위에 biphosphonate와 steroid 투여로 최근수상부위의 근육 골화와 경화를 현저한 호전을 보였으나, 기존의 골화가 이미 진행된 병변에서는 잘 반응하지 않음을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Fibrodysplasia ossificans progressiva(FOP) is an extremely rare hereditary disorder characterised by progressive heterotopic ossification of the soft tissue. The resulting progressive immobilization of the limbs, jaw and chest wall generally leads to severe disability. We present an 20-rear-old man with advanced FOP. He had two operative interventions by prior traffic accident and recent biopsy. It resulted abnormal ossification. Treatment for this disorder is avoidance of exacerbating factors and medical strategies is biphosphonate and steroid. We observed the course of ossification and muscle atrophy during biphosphonate and steroid therapy in advanced FOP.

高溫에서 疲損勞傷이 Stainless Steel의 破壞靭性에 미치는 影響에 關한 硏究

鄭世喜,林載奎,李宗基 전북대학교 1982 論文集 Vol.24 No.-

The latest industrial machinery is usually used under the severe conditions such as high temperature, high pressure and high load because it needs the best efficiency. The austenitic stainless steels(SUS 316) are well suited for high temperature and high pressure service because of their creep resistance and high ductility. In this paper, in order to investigate the variation of fracture toughness of the specimens given repeat stress at 450℃, decreasing temperture of ductility, instrumented charpy impact test was carried out from-150℃ to 100℃. The results are summerized as follows ; 1. The fatigue life at 450℃ is reduced by 70 percent than that at room temperature. 2. When the specimens are damaged by the fatigue at 35kg/㎟ and at cyclic numbers with the same ratio on N_f, the difference between 450℃ and room temperature in hardness increasing ratio is 7%, and 5% at 30kg/㎟ 3. The maximum distance of work hardened zone by the fatigue damage at room temperature is larger than at 450℃. It means that the plastic deformation occurs easily because the yielding stress is lower at room temperature than at 450℃. 4. The fracture energy(E_f) decreases with the increase of nominal stress and rate of damage.

林載奎,鄭世喜 全北大學校 1982 論文集 Vol.24 No.-

In order to study the change of fracture toughness owing to post weld heat treatment of welded specimens under the elastic bending deformation, after post weld heat treating of four different conditions, that holding time is 0, 1/4hr, 1hr and 10hr, on the welding joint of the high strength steel with bead on plate, tested the low temperature fracture toughness, observed the microstructure and measurred the microhardness. We obtained the results as follows. 1. Fracture toughness depends upon the heat treatment conditions. 2. Fracture toughness of the specimen under the pre-strain remarkablly increased until the holding time of the heat treatment is one hour, but it was almost saturated over the one hour. 3. Tempering the welding HAZ with the maximum (H_v=250), it became soft to H_v=170, but tempering under the elastic straining (ε=0.024), increased the hardness to the H_v=210. 4. Tempering at the condition of the elastic strain on the HAZ structure, fracture toughness greatly depends upon the hot working deformation.
