Physical properties of waterborne soft feel coatings for instrument panel were investigated. Soft feel coatings give warm and velvet touch for cold and hard plastic materials. Waterborne soft feel coating is composed with two parts. Part A contains polyester polyurethane dispersion (PE-PUD), OH-functional water dispersible polyurethane resin (PC-PUD) and OH-functional water dispersible alkyd resin (OH-PA). Part B contains hydrophilic hexamethylene diisocyanate trimer (HHDI). Soft feeling of coated panel was related with the amounts of PC-PUD and OH-PA. The physical properties of coated panel could be controlled by the NCO/OH ratio from Part A and Part B. Soft feeling was enhanced with relevant to PE-PUD content but the content of PE-PUD was limited because of weakening of coated film strength. For excellent touch and good property, the optimum composition of soft feel coat was PC-PUD(30%) and PE-PUD(20%). The results from all reliability tests satisfied soft feeling, scratch, chemical resistance and fogging.

The purpose of this paper is to examine the current status of physical education so that its objectives and nature may be ascertained and an appropriate course of development might be found. According to Erich Fromme, the approach to life can be seen as either possession oriented or existence oriented. In the possession oriented mode even knowledge is seen as something which is possessed. Current physical education is based on the possession oriented approach. It is imperative then that physical education must reorient itself so that it might serve the existence oriented mode of being and facilitate the quest for the significance of this mode of being. As to the question of “Why is the recovery of this knowledge of existence inseperable from physical education?”. The reason lies in the fact that existence is experiential and physical education is the most fundamental of all forms of education when it comes to the experience of human existence. Physical activity is not an act of observation but requires direct participation. The thing which enhances this experience is the imagination. The imagination helps us take the experience of human movement to a higher level. The point which physical education must convey is that which the individucal personally discovers through direct experience. Therefore the essence of physical education can be summed up as “realization through movement.” In distinguishing the approach of physical education from other approaches, the following three points are salient; 1. Physical education emphasizes experiential physical activity. 2. The significance of expression is emphasized. 3. A physical way of thinking is emphasized. Be offerring the experience of physical activity to students, the beauty of human existence can be discovered and the significance of that kind of lifestyle might be realized. physical education then, in the midst of a diminishing sense of humanity seen in our mechanized civilization, will play a vital role in rediscovering this humanity and restoring its original from to mankind.

Tracheobronchopathia osteoplastica is a rare disorder of unknown cause characterized by the projection of numerous bony or cartilaginous submucosal nodules into the tracheobronchial lumen with sparing of the posterior membranous portion of tracheobronchial tree. In the past, most of the cases were diagnosed as secondary finding at autopsy. Nowaday, the key component of the evaluation is flexible fiberoptic laryngoscopy and bronchoscopy, which typically demonstrates irregular spicules of subrnucosal bone and cartilage projecting into the tracheobronchial lumen and causing various degrees of airway obstruction. A 45 years old man was visited Sunchon St. Carollo hospital due to discomfort on throat. We saw several nodules just below vocal cord via laryngoscope. The computed tomography revealed multiple small calcified nqdules on trachea and both main bronchi. Pathologic finding of bronchoscopic biopsy showed abnormal proliferation of bony and cartilagious nodules in the tracheal submucosa. These fingdings were consistent with tracheobronchopathia osteoplastica. We report here on a case of tracheobronchopathia osteoplastica with review of literature.

Silicon-to-silicon anodic bonding was accomplished using lithium doped interlayer. Lithium doped interlayers were deposited on silicon substrates by electron beam evaporation, which has a fast deposition rate compared with sputtering method. Silicon-to-silicon bonding occurs in the range of temperatures from 250℃ to 300℃ with the applied voltages from 70V_(DC) to 100V_(DC). The bonding strength obtained from tensile test was about 5MPa under the condition of 80V_(DC) in 300℃. The surface morphology of lithium doped interlayer was studied with the atomic force microscopy (AFM). Finally, secondary ion mass spectroscopy (SIMS) analysis was carried out in order to investigate the role of the lithium ions in bonding mechanism.

The objective of this study is to illuminate the value of performance as the source of knowledge in physical Education. In the pursuit of the above research objective the following things were considered; A) The current direction being pursued in physical education was examined. B) An attempt was made to clarify ‘physically derived knowledge’, under the premise that it should be centered as the unique domain of physical education. C) While re-interpreting the concept of physical education based of the premise of ‘physically derived knowledge’ the essential value of physical education was examined. D) The ideal course of development of physical education in relation to the mode of physically derived knowledge and the human originality and realization inherent in this were examined. Ultimately, through a re-eveluation of the current state of physical education we have attempted to illuminate the estrangement of physical education from it's core concern, that is, the value derived from movement by the human being. Futhermore, an attempt was made to identify that aspect of physical education which is unique only to physical education, that is, knowledge derived from human movement or from the physical demension of human existence.

[1.1.1]propellane has an inverted structure at the two bridged carbon atoms. Interbridgehead bonding character of [1.1.1]propellane was described by p-p(σ) bond. Interbridgehead bond distance is longer than normal C-C bond and it's charge distrbution is about four-fifths of a normal C-C bond So [1.1.1]propellane undergoes facile free radical addition reactions. 1,3-Diiodobicylo [1.1.1] pentane was synthesised by irradiating [1.1.1]propellane and 1_(2) in ether/hexane(1:5) The reaction of 1,3-Diiodoboicyclo[1,1,1]pentane with Sodium sulfide produced unexpected products (ring opening product, linear polimer). But we tried thes reaction under high dillution for inhibition of polymerization These products were separated by preparative G.C and TLC and characterized by H-NMR, GC-MS, ^(13)C-NMR

목적: 압박고 나사를 이용한 전자간 골절의 수술적 치료 후 발생할 수 있는 고정실패에 영향을 줄 수 있는 인자들을 분석하고자 한다. 대상 및 방법: 1996년 2월부터 2001년 2월까지 본원 정형외과에서 압박고 나사를 이용하여 수술한 전자간 골절 환자 중 6개월 이상 추시가 가능하였던 79명을 대상으로 하였다. 고정실패는 12례였으며, 고정실패에 관여할 것이라고 기대되는 다음 인자들에 대하여 분석하였다; modified Evans 분류, Singh 지수, 대퇴 골두내 나사의 위치, 골절의 정복양상, 이 인자들을 chi square test를 이용하여 통계적으로 분석하였다. 결과: 나이와 연령은 통계적인 차이를 보여주지 못했다 (p>0.05). 골절의 안정성을 기준으로 나눈 두 군데에서는 의미있는 빈도의 차이를 보여주었다 (p<0.05). 대퇴 골두내 나사못의 상방위 치한 경우와 골절의 수술적 정복 후 전후 사진상 5㎜ 이상 전위된 경우에도 의미있는 차이를 보여주었다 (p>0.05). 결론: 나이, 성별, Singh 지수는 고정실패에 영향을 주지 않았다. 고정실패에 영향을 주는 요소는 다음과 같다고 사료된다; 나사못의 골두내 상바위치, 불안정한 골절양상, 골절의 수술적 정복 후 방사선 전후 사진에서 보이는 5㎜ 이상의 피질골의 전위. Purpose: To evaluate the factors which might affect the loss of fixation after surgical treatment of intertrochanteric fracture with compression hip screw. Materials and Method: From February 1996 to February 2001, seventy nine cases of intertrochanteric fracture which we operated with compression hip screw was reviewed with minimal follow up for 6 months. There were twelve cases of loss of fixation. The cases were analyzed according to each factors which we thought to affect the loss fixation. The factors are fracture type by modified Evans classification, Singh index, placement of screw in femoral head, quality of reduction. Then we analyzed these factors with chi square test. Result: Difference between age group and sex were not thought to be statistically meaningful factors (p>0.05). There were difference of prevalence between two group divided by fracture stability (p<0.05). In cases of superior placement in femoral head, there were more loss of fixation. Displacement of cortex of proximal femur of radiologic AP view other than laterial view showed meaningful difference (p<0.05). Conclusion: Age, sex, Singh index did not affect the loss of fixation. But, next factors as follows affected the loss of fixation; Superior placement of hip screw, unstable fracture pattern, displacement of fracture site more than 5㎜ after reduction on radiologyc AP view.
