This study is to measure the thermal resistance of 7 types of Parka of different materials with thermal manikin and to compare their effects on physiological responses & subjective wear sensations. Following are the results obtained from the experiments 1) From the thermal manikin experiment, i) As an outer layer, although not significant, water proof fabric was warmer than water proof-vapor permeable fabric. ii) In case of insulating material, down was better for thermal resistance than polyester wadding of the same thickness. Moreover, as the down was thicker, it had more efficiency in thermal resistance. However, the marginal efficiency of thickness was found to be decreasing. 2) From the male-subject experiments, i) Chest temperature, mean skin temperature & microclimate temperature showed the same results on thermal resistance as those of the thermal manikin experiment. ii) Only during rest periods, there was a significant difference among 5 insulating materials in the sense of microclimate humidity. The almost same conclusion was obtained from the above experiments. Even the outer layer did not significantly affect thermal resistance & subjective wear sensation, insulating materials had a significant influence upon them. But in case of 3.5 cm down, it gave less comfortable than that of the thinner. Therefore the optional one for the best comfort & thermal resistance among 7 combinatins is the outer layer of water proff-vapor permeable & insulating material of 2.1 cm down.

Purpose: The purpose of this study was to identify factors associated with the intention of the prostate cancer screening (PCS). To achieve this purpose, a structural equation model was established based on the health belief model and the theory of planned behavior. Methods: The subjects of this study were 260 male participants who were between 40 and 74 years old and had not taken the PCS. Data were collected using a structured self-report questionnaire (i.e., perceived benefits, perceived barriers, attitude, subjective norms, perceived behavior control, and intention of the PCS). Descriptive statistics, reliability analysis, correlation analysis, confirmatory factor analysis, and fitness test were used to test hypotheses. Results: The intention of the PCS was directly affected by the perceived behavior control and indirectly influenced by the perceived benefits. The structural equation model also showed that the perceived behavior control explained 78% of the intention. Conclusion: To raise the intention to take the PCS, it is necessary to increase the confidence of a subject that may control its difficulties and inform the perceived benefits of the PCS to a subject.

The aims of this research study is to clear the differences of the learning effects and the cognition of Home Economics by sex in the middle school and to collect the future-oriented educational dates, after implementing the 6th education curriculum. The results of the study are as follows ； 1. Most of students had the cognition that Home Economics is a subject matter of a needful knowledge and skill for the family life, half students a cultural subject matter for the modern life. The former was supported by female students, the latter by male students. 2. Most of students were interested in actual training fields of cooking and hand-sewing, had a strong interest about a field of physical and social-psychological growth. The differences by sex interest about significant in these fields. 3. Most of students had positive responses in the learning effects of Home Economics. The most useful field was cooking and the worst was the structure and method of sewing machine. 4. The shortage and the dissatisfaction in the learning of Home Economics were lacking of the actual training hours, the old-fashioned teaching methods and the shortage of teaching materials etc.

The purpose of this study was to examine elementary teachers' perception on birds and problems on teaching it. For this study, the science textbooks from 3rd grade to 6th grade according to the 7th national curriculum were analyzed. Results revealed that, firstly, there were 34 bird species recorded and these were described 55 times in the surveyed textbooks. Secondly, the survey showed that $20\%$ of the teachers were interested in birds despite the fact that $98\%$ of them had no special knowledge about birds nor had studied them in college. Additionally, it was revealed that $41\%$ of the teachers felt lacking in specialist knowledge about birds and this lead to difficulties in teaching on this subject. Thirdly, academic backgrounds had an affect teachers' perceptions on teaching this area. The teachers' levels of interest in birds and the teachers' ratio of teaching on this topic tended to increase as their academic careers developed, and the proportion of male teachers in this category were higher than female teachers. To overcome difficulty in teaching on this area, it is suggested that a reconstitution of subject materials, as well as a revision of the teachers' guidebooks be undertaken.

Background: The purpose of this study was to identify the effects of morphological Change of cervical spine to apply to neck retraction and extension regarding the straight deformity of cervical spine. Methods: A 40-year male subject with straight deformity of cervical spine participated in this study. The study subject underwent a cervical lateral radiography on the static position, neck retraction and neck extension on standing. Measurement method were using computer-based digital radiogram on a picture achieving computer system forthe centroid method, Cobb's angle and Jackson's angle. Results: Neck retraction was increased kyphosis on the C2-4 with lordosis on the C5-7. Neck extension was increased lordosis on the C2-7. Conclusions: These findings suggest that neck retraction was increased kyphosis and neck extension was increased lordosis based on the straight deformity of cervical spine. Therefore, we should be consider that neck extension exercise when increased lordosis for the patients of straight deformity of cervical spine.

This research employs the grounded theory approach among various qualitative methodologies in order to reach a deep understanding of both the experiential process that children undergo in block play and the essential meaning of it. The objects of this study are 22 children(female 7, male 15) in a 5-year-old class of K kindergarten at Guro district, Seoul. The result of this research shows that first, children take pleasure in block play because of the delight and sense of accomplishment in building, the joy in demolishing, and the happiness of embracing the world through dramatic play with building structures. Second, the characteristics of children's block play are popular subject of the play, decision of the subject, impromptu transformation and elaboration of building structures, and flow of the play according to friend/non-friend relationship. Third, the implicit rules shared by children have more significant influences upon the block play than the agreed rules at the beginning of semester.

This study compared the Character Studio of 3ds Max and OpenGL to find an adequate modeling method of character animation to be used in motion analysis in the area of motor mechanics. The subject was one male golfer. We obtained the positional coordinates of marks needed by photographing the subject's golf swing motions. Because the method based on the Character Studio used meticulously designed character meshes, it enabled high.level animation but it took a long time in applying physique and demanded the repeated adjustment of each motion data. With the method based on OpenGL, a character completed once could be usable to almost every testee and desired program control was available, but because each character had to be created by making a computer program, it was hard to make characters delicately. Because the method using the Character Studio is actively studied not only in motor mechanics but also in many research areas, it is expected to be more usable in the near future. On the contrary, the method based on OpenGL is easily applicable and allows the convenient use of other mechanical data.

This paper deals with the whole-body vibration and ride quality evaluation in the vertical direction. The responses of the floor, hip, back, and head in four subjects were measured for various seats when the floor was excited by random vibration with r.m.s of 1.2m/s2 in the vertical direction. In the transmissibility between the hip and floor, the fundamental mode is observed at 4.4 Hz. In the transmissibility between the head and floor, the fundamental mode at 4.4Hz and the second mode at 7.6Hz are observed. It is shown that the head motion is 41% larger than the hip motion and the response of female subject is larger than that of male subject. The response without backrest also was compared with that with backrest. From these human responses ride quality of five seats were evaluated by the ride value such as transfer ration having frequency weighting function is the statistical sense. It is observed that the seat having high damping property can reduce the most acceleration exposed to hip in the statistical sense for all ride valves, while the seat having different seat spring doesn't show statistical difference.
