The purpose of this study is to improve clothing construction by analyzing form variation of upper trunk & upper arms with the use of plaster cast. Experimental research was performed by plaster gypsum method. The subjects were males between age 21 and 25, classified Standard somatotype by their bust size and Rorher Index. Arm movements were consisted of 5 types(0$^{\circ}$, 45$^{\circ}$, 90$^{\circ}$, 135$^{\circ}$, 180$^{\circ}$) to each vertical motion in front. The statistical analyses used in this study were mean, standard deviation, repeated mesure design. The result obtained from this study were as follows; 1. As a result of investigating into the rate of the expantion and contraction of basic body-surfact-lines, the side seam length showed the maxium rate of expantion in 180$^{\circ}$ degrees, the shoulder length showed the maxium contraction in the same degrees. 2. The variation of the upper part of the body form by increasing the upper limb motions, shoulder point was moved to be the inside or upside. And the anterior armfit point, posterior armfit point and armfit point were moved to upside. The form of the armhole-line in Drafts of a body surface was differently changed by increasing the movements. 3. Increasing the upper limb motions, the height of sleeve cap decresed and width of the sleeve decreased but girths of the sleeve cap was not show consistant change.

The purpose of this study was developing the building materials for creation the comfortable IAQ. By reducing formaldehyde(HCHO) known as the main factors of Sick House Syndrome. This material must be revealed the physical and eco-friendly performance, so this study set up the basic standards for building materials. The source of physical performance evaluation is Korea Industrial Standards and the base of environmental ability is the Eco Label considering certificated system related to an apartment house. Because the developed material was satisfied with the established standards, it was tested in mock-up room for obtaining the real date from indoor air. The mock-up test was conducted according environmental standard method for indoor air Quality of the ministry of environment. The result of this study were as follows; the functional building materials had a effect to reduce the formaldehyde concentration for a initial period without wall paper, so additional development is needed for application with the wall paper and the available period.

Tensile strength is considered key properties for characterizing rock material in engineering project. It is determined by direct and indirect methods. Point load test is a useful testing method to estimate the tensile strengths of rocks. In this paper, the effects of rock shape on the point load index of gypsum are investigated by PFC2D simulation. For PFC simulating, initially calibration of PFC was performed with respect to the Brazilian experimental data to ensure the conformity of the simulated numerical models response. In second step, nineteen models with different shape were prepared and tested under point load test. According to the obtained results, as the size of the models increases, the point load strength index increases. It is also found that the shape of particles has no major effect on its tensile strength. Our findings show that the dominant failure pattern for numerical models is breaking the model into two pieces. Also a criterion was rendered numerically for determination of tensile strength of gypsum. The proposed criteria were cross checked with the results of experimental point load test.

This study performed lateral load testing on seventeen wood wall frames in two sections. Section one included eight tests studying structural foam sheathing of shear walls subjected to monotonic loads following the ASTM E564 test method. In this section, the wood frame was sheathed with four different types of structural foam sheathing on one side and gypsum wallboard (GWB) on the opposite side of the wall frame, with Simpson HDQ8 hold down anchors at the terminal studs. Section two included nine tests studying wall constructed with oriented strand board (OSB) only on one side of the wall frame subjected to gradually applied monotonic loads. Three of the OSB walls were tied to the baseplate with Simpson LSTA 9 tie on each stud. From the test results for Section one; the monotonic tests showed an 11 to 27 percent reduction in capacity from the published design values and for Section two; doubling baseplates, reducing anchor bolt spacing, using bearing plate washers and LSTA 9 ties effectively improved the OSB wall capacity. In comparison of sections one and two, it is expected the walls with structural foam sheathing without hold downs and GWB have a lower wall capacity as hold down and GWB improved the capacity.

This study was made to draft the tight fitting bodice pattern which horizontal and perpendicular stands are to be lightly set, with the consideration of characteristics of body shape in design of clothes. Measurement of body was conducted on 53 women in twenties, and observation was made on surface development pattern by adhesive tape addition method and gypsum method on three standard objects. In the study, bodice pattern was completed by using already made Somato- measurer, compared with existing bodice pattern, and the results are as follows. The result of the correlation analysis by body measurement shows that chest circumference has a relation to B$.$P-front neck point, side neck point, shoulder point, front interscye breadth point, and the item in spine scapulae point has relation to the item of back neck line, and front & back horizontal values. The degree of shoulder slant, width of armhole and of its depth, the amount of breast, back space, back length were shown to be directly measured from the body. In surface development pattern, tight-fit bodice pattern necessary to the breast volume and back space were shown to be investigated and these volume have to be given in setting up basic line for clothes design together with body measurement value. The result of sensory evaluation for appearance test on fitness shows higher value of research bodice including line of shoulder line, front and back interscye breadth, chest circumference, waist circumference, armhole circumference and of its depth, compared with the research bodice in most items. The result of this study is seen showing high effectiveness for the basic data to design the ready-made dress of high sensitivity of high value added tat.

Data of the body surface is a necessary unit for the measuring of metabolism energy and activity energy. And also, these data are referring to check the degree of retaining warmth of clothes, to find the effect of heat insulation according to body surface, to calculate an average temperature of skin, and to study the several fields of clothing. In measuring of body surface, it si actually impossible to measure a subject's body surface in each experiment. As the experimental method, both gypsum method, by which the shape of body an be copied as it is, and the weighting method from which planed body surface area can be measured with consistent thickness of polyprophylene film as used. In fact, every female subject feels uncomfortable to measure her body surface as a naked body. There, it is providing a simple, accurate regressive equation with weight & height as variable factors in this study. This equation is as=117.02W+77.31H-3344.94 with average error : 0.1%, absolute average error : 2.07%.

국내 초고층 프로젝트의 증가에 따라 필연적으로 고강도 콘크리트의 사용이 증가되고 있다. 콘크리트의 강도가 증가됨에 따라 화재시 단면결손을 유발하는 폭렬의 경향성이 커지고, 콘크리트부재 내부의 온도를 현저하게 증가시키며 심각한 구조적 손상을 유발할 수 있다는 문제점이 대두되었고, 정부에서도 2008년 7월부터 고강도 콘크리트의 내화성능 관리기준을 시행하고 있다. 이에 국내 각 건설사들은 50MPa 이상의 고강도 콘크리트에 대하여 폭렬방지 대책을 수립 중에 있다. 본 연구소에서는 신축공사 및 리모델링공사에도 적용이 가능한 고강도 콘크리트 폭렬방지 공법인 PFB (Posco E&C Fire Board) 공법을 개발하여 지속적인 공법 개선에 노력하고 있다. 본 연구는 고강도 콘크리트 폭렬방지 대책으로 개발한 PFB 공법을 기존의 습식공법에서 현장적용성 및 경제성이 우수한 건식화 공법개발을 위한 기초 연구로 PF보드의 기초물성 평가, 3시간 내화시험 및 현장 적용위한 실시 상세 설계를 실시하여 당사 초고층 현장에 적용하기 위한 기본 자료로 활용 하고자 하였다.
