  • 암반 내 형성된 과도한 초기응력장은 굴착 공동 주변에 점진적이고 국부적인 취성파괴를 유발시킴으로서 시공의 안정성과 경제성을 확보하는데 장애 요인으로 작용할 수 있다. 이 논문에서는 응력 수준 증가에 따른 공동 주변의 취성파괴 거동 특성을 파악하기 위해 축소된 원형 터널 공시체를 이용한 이축압축시험과 입자 결합 모델을 이용하여 개별요소법의 일종인 $PFC^{2D}$ 해석에 의한 연구를 수행하였다. 실내 이축압축시험을 통해 취성파괴의 발생 영역과 형태 면에서 실제 암반 공동 주변에서 발생된 파괴 특성과 유사한 파괴 거동을 모사할 수 있었다. 응력 강도비 증가에 따라 진행된 균열 발전단계를 미소파괴음 특성 변수들에 대한 상세 분석을 통해 평가하였다. $PFC^{2D}$ 해석을 통해 공동 주변에서의 미세 균열 발생과 전파 과정을 성공적으로 가시화하였으며 이를 통해 이축 압축시험 결과의 신뢰성과 시험방법의 적정성을 확인할 수 있었다.

  • Purpose: Anatomic configuration of the ankle joint is useful information during various ankle procedures. This study was prospectively designed to investigate the sagittal inclination pattern of the ankle joint. Materials and Methods: Lateral standing ankle radiographs from one-hundred people (age: $17{\sim}68$, M:F=45:55) and magnetic resonance (MR) sagittal ankle images from twenty-four people (age: $16{\sim}65$, M:F=14:10) were studied. Post-traumatic, arthritic, or grossly deformed ankles at any reason were excluded. The posterior inclination angle (PIA) of the distal tibia was measured and compared between the lateral and the medial segment. Results: On plain radiographic data, the average PIA of the distal tibia was $6.14^{\circ}{\pm}3.56^{\circ}$ (range $0^{\circ}$ to $14^{\circ}$) in the lateral segment and $13.16^{\circ}{\pm}3.05^{\circ}$ (range $6^{\circ}$ to $22^{\circ}$) in the medial segment. On MR imaging data, the average PIA of the distal tibia was $5.08^{\circ}{\pm}4.26^{\circ}$ (range $1^{\circ}$ to $10^{\circ})$ in the lateral segment and $10.16^{\circ}{\pm}4.87^{\circ}$(range $5^{\circ}$ to $17^{\circ}$) in the medial segment. The PIA between two segments was significantly different. Conclusion: The sagittal configuration of the medial area ankle joint and the lateral area ankle joint has difference in the degree of posterior inclination and shape of curvature.

  • The purpose of this study is to find the differences among the clothing brands through examination of present situation about uniform design in domestic coffee houses and provide the basic materials in developing uniform designs to reflect the brand identity. For research contents and method, the overall circumstances were examined about the domestic coffee houses and their uniforms at large via literature review. Then, characteristics on their 10 uniform designs were reviewed according to item, color, pattern and accessary. The following are results. First, cardigan, cap, and necktie according to the individual brand are added with basis of shirt and apron in composition of coffeehouse's uniform. Second, in cardigan, those colors including black, navy and brown are used, reminding of the coffee. Brand logo or symbol is also presented on it, which addresses the brand image. Third, the kind of shirt consists mainly with long or short shirt blouse and long sleeve or short sleeve pique shirt. Job title or gender differentiates the shape and color. Fourth, one-piece type is commonly applied for the apron. At the same time, a short skirt is put on as well. An image expression is often found by the unique brand color also, but mostly, some dark tones like brown or black are largely used. Fifth, in cap, various kinds are worn including the cap as in the case of baseball, fedora, beret, and hunting cap. In color, black or brown color same to that of apron is common, which fails to show differentiation. Thus, consideration of color remix with application of brand symbol is thought to be an alternative to this.

  • Background and purpose: Cardiovascular disease will undoubtedly rise along with the aging of the 'baby-boom' generation. The purpose of this study is to find the new index of the cardiovascular aging. Methods: The effects of aging on the heart and the arterial system are surveyed in the point of structure and function. Results: Arterial stiffening is due to the fatiguing effects of periodic stress on the arterial wall and is the main reason for increasing pulse wave velocity. The systolic hypertension is caused by the early return of wave reflection. The increased after-load by the arterial change leads to the development of left ventricular hypertrophy. The reduction in left ventricular compliance cause the impairments of the diastolic function. In contrast to the lower limb, aging effect in the upper limb are almost due to the ascending aortic pressure wave and the reflected wave from the lower limb. Conclusion: We have the following points. (1) The change of physiological pulse pattern by age can be explained by the early returning of reflected wave. (2) The atrial pulse in old age are generated by the left ventricular hypertrophy.

  • The purpose of this study is to research on the actual condition of production and selling in silver apparel market. For the questionnaire, 19 women's wear brands which were in higher ranking of sales in boutiques and madame-zone of department stores were selected. Pattern makers of each brand were questioned about 40 items for this research. The results of the questionnaire were as follows: 1) According to the result of the survey on the made-to-wear production of 19 ready-to-wear manufacturers, there was the gap was in ages between the target and the real consumer. Consumers of these brands were older and aged more broadly than their target ages. 2) Most of the consumers of silver-zone has thick waists, common heights, fat shapes. Custom-made clothes are ordered in many cases because of the big abdomen(50.0%) and H-shape(58.3%) of a somatotype. The body size variation of user population is needed for a good fit. 3) All brands(100%) of this research are using KS standards in the label of clothing, but they don't use these data in their production by reason of unawareness and distrust about these data. These inconsistency between the label and the real size of products may cause a confusion when consumers buy ready-to-wear. 4) Silver apparel manufacturers have need of anthropometry information and dummy(78.6%) suitable for their target consumers to increase their satisfaction about their apparel fit.

  • Air interlacing serves to protect the yarn against damage, strengthens inter-filament compactness or cohesion, and ensures fabric consistency. The air interlacing nozzle is used to introduce intermittent nips to a filament yarn so as to improve its performance in textile processing. This study investigates the effect of interlacing nozzle geometry on the interlacing process. The geometries of interlacing nozzles with multiple air inlets located across the width of a yarn channels are investigated. The basic interlacing nozzle is the yarn channel, with a perpendicular single air inlet in the middle. The yarn channel shapes are cross sections with semicircular or rectangular shapes. This paper presents three doubled sub air inlets with main air inlet and one of them is slightly inclined doubled sub air inlets with main air inlet. The compressed air coming out from the inlet hits the opposing wall of the yarn channel, divides into two branches, flows trough the top side of yarn channel, joins with the compressed air coming out from the sub air inlet and then creates two free jets at both ends of the yarn channel. The compressed air moves in the shape of two opposing directional vortices. The CFD-FASTRAN was used to perform steady simulations of impinging jet flow inside of the interlace nozzles. The vortical structure and the flow pattern such as pressure contour, particle traces, velocity vector plots inside of interlace nozzle geometry are discussed in this paper.

  • This study is to classify somatotypes of the upper class boys in elementary school. The study is conducted through anthoropometric measurements and photometric measurements. The subjects are 320 boys in the age group of 10 to 11 years old. The following conclusions are drawn from this study. 1. The height items are increased along with age increase. The increases in the factors, which specify vertical sizes such as height and length, are a little larger than those of breadth, depth, and girth, which specify ; horizontal sizes. 2. The factor analysis on anthropometric measurements and photometric measurements reveals five somatic composition factors and those factors comprised 79.60% of total variance. 3. The torso shapes of the upper class boys in elementary school are classified into three categories. The first type is taller and heavier than the average elementary school upper class boys and has the highest rising shoulders. The shape of the back is about average and the chest is developed above average. The curvature of the lower back is gentle and lower abdomen protrudes the most of the three types. The second type is tall and slightly heavier than average and shoulders are raised a little. The shoulder blades protrude about average and the curvature of lower back is the most developed of all. The cheat is developed about average and the abdomen is a little protruding. The third type is the most common with the smallest height of the three and skinny with dropped shoulders. The chest is somewhat flat and the shoulder blades protrude about average.
