The purpose of this study was to develop a grading increment at armhole area by apparel CAD(Computer Aided Design) system. In developing a grading increment at armhole area, we analyzed ease values of armhole area in bodice and sleeve by manual drafting patterns of five sizes. We suggested grading increments applied Pythagorean theorem to development the grading increment of the armhole of sleeve. The results and discussions of this study were as follows: 1. In drafting each size, the ease values were not identical. It was difficult to draft perfectly the same armhole line shape between sizes. 2. According to our developed grading increments applied Pythagorean theorem, the ease values were identical between sizes and difference of the armhole length between sizes was also identical. 3. The grading formulas were made out for apparel CAD system. Once grading increment or formula is set in the computer, it can be easily altered to various clothing items at any time. The efficiency of grading work will be also improved and grading time will be reduced.

The purpose of this study is to develop the size and grading increments chart for the middle-aged obese women compared with normal women in middle age. Seven hundred and thirty three women's data from the 4th National Korean Size Survey for Standardization (1997) were analyzed. It was found that size increment of bust and hip girth of obese women was different from that of ordinary middle-aged women. The rate of coverage for a certain set of size specification and the grading increment value for the clothing of Korean obese women in middle aged group were also suggested. The relative percentage value of grading rule based on the change in bust girth increment of Korean obese women was quite different from that of American women. In conclusion, it was noted that the characteristics of the body size specification of obese women was quite different from those of the corresponding age group, so that the separated size specification and grading rule are needed to be used in the manufacturing process of obese women's clothing.

The purpose of this study was to research grading work according to the targets of women's wear manufacturers in Korea. For the questionnaire, 91 women's wear brands, which were in higher ranking of sales, were selected, and the age groups were separated into 3: 20's, 30's, and 40's & 50's, according to their customers. The graders of each brand were questioned about 20 items for this research. The results of the questionnaire were as follows: 1 The brands for older women manufactured more sizes and cared more about somatotypes fur grading than other brands did. 2. For upper garments on the basis of bust girth, the numbers of dimensional increments were different depending on the age groups: 9 for 20's, 7 for 30's, and 7 for 40's & 50's. 3. For lower garments on the basis of hip girth, the numbers of dimensional increments were different depending on the age groups: 9 for 20's, 6 for 30's, and 5 for 40's & 50's. 4. As a model size of grading, many brands used the smallest size, but the brands for 40's & 50's also used the second size. 5. The parts needed to be corrected after grading were sleeve ease, armhole, shoulder line, neckline, crotch curve, etc. The grading with CAD system had more correction after grading than hand grading.

This study was intended to analyze conventional grading increments and methods for middle-age men's pants, and to suggest new grading guidelines that will enable to improve satisfaction with size and silhouette as a result of combining the concept of grading, which help maintain the ratio and proportion by sizes as one of ready-made apparel's advantages, with body form oriented and aesthetic approaches. In the apparel industry, the current sizing specifications and methods adopted by relevant companies, as well as the characteristics of body forms of men aged 35 to 55 years were comparatively analyzed to find out problems and ultimately to suggest their solutions or improvements. It was considered that as the conventional grading practices used in the industry were customary on the basis of the past experiences, it was required to take the body forms of target consumers into account and also, to reconsider the conventional grading methods. Analyses of sizing and specifications by brands show that 4 to 19 sizes including 82 or 84 as standard size have been produced. Since men's apparel has a large number of sizes with the large range of sizes, grading is critically important. As silhouettes depend on the distribution of grading rule values at each point of increment pattern in the main regions during grading, it is necessary to consider both size grading and form variations. To maintain an appropriate silhouette with keeping the angle of center back line of a pattern, it is desirable to set the ratio of side line part to center part from the crease line to approximately 3:7. It is required to diversify the values of grading rules according to different sizes and pattern regions in consideration for the body forms of key consumers. In addition, if the natural lines of designs and patterns for the width increments of waist circumference and hip circumference, the increments of hip width in pant's front and back panels, the ratio of grading rule values of the right and left sides of crease line, knee circumference, thigh circumference and so on are taken into account, grading will be satisfactory in the all aspects of size, silhouette and ratio.

The purpose of this study was to research specific dimensional increments of grading and to support to establish a grading system according to the targets of women's wear manufacturers in Korea. For the questionnaire, 91 women's wear brands, which were in higher ranking of sales, were selected, and the age groups were separated into 3: 20's, 30's, and 40's & 50's, according to their customers. The graders of each brand were questioned about specific dimensional increments of grading fur this research. The results of the study were as follows: 1. Using the most common dimensional increments, 3.81cm(1 f inch) and 5.08cm(2 inch) for upper garments and lower garments, the modes of increments and reference increments for each garment section were suggested. 2. For upper garments, the brands for older women made larger increments of waist girth than for bust girth. This was to cover abdominal obesity. Also, the brands made larger increments of girth than for shoulder breadth. 3. For lower garments, the brands for older women made larger increments of waist girth than fur hip girth. It meant the drop value of hip girth minus waist girth was smaller. The breadths of front and back crotch were also wider.

한국 육우의 거의 90%를 차지하는 한우의 역사, 산업 특성 및 소고기 생산을 중심으로 한우의 현안과 미래를 논의했다. 한우산업에 많은 변화가 있었지만 여전히 한우는 한국 소비자에게 최고의 쇠고기 공급원으로서 프리미엄의 위치를 가지고 있다. 다른 농업 기반경제와 비교할 때, 한우 농민의 수는 최근 수십 년 동안 급격히 감소했으며 농장의 규모가 커지고 시스템이 보편화되었다. 수입 소고기와의 차별화, 사료비 증가, 송아지 가격의 증가, 토지 비용의 증가 등 한우산업이 직면 한 어려움을 해쳐나가기 위해서는 보다 젊고 똑똑한 농부들이 필요하다. 기존의 축적된 노하우와 새로운 기술을 잘 접목시켜 한우를 잘 기르는 사람들이 많이 생겨나야 하고 소득을 창출하여야 한다. 우리나라의 발전된 ICT기술과 농민들의 근면함이 잘 융합되어 고급데이터 들이 꾸준히 축적된다면 여러 가지 어려운 상황에서도 새로운 고급육 생산 프로그램을 개발할 수 있고 이를 활용한 원천기술 개발로 지속가능한 한우산업을 유지할 수 있을 것이다. 아울러 기존의 방식과 다르게 변화하고 있는 4차 산업혁명시대에 한국형 정밀축산을 개발하여 축산선진국으로 나아갈 수 있을 것이라 기대한다.

The study was conducted to determine the effect of Malaysian jungle Tualang Honey (TH) on development of breast cancer induced by the carcinogen 7,12-dimethylbenz(${\alpha}$)anthracene (DMBA) in rats. Forty nulliparous female Sprague-Dawley rats were given 80 mg/kg DMBA then randomly divided into four groups: Group 1 served as a Control while Groups 2, 3 and 4 received 0.2, 1.0 or 2.0 g/kg bodyweight/day of TH, respectively, for 150 days. Results showed that breast cancers in the TH-treated groups had slower size increment and smaller mean tumor size (${\leq}2cm^3$) compared to Controls (${\leq}8cm^3$). The number of cancers developing in TH-treated groups was also significantly fewer (P<0.05). Histological grading showed majority of TH-treated group cancers to be of grade 1 and 2 compared to grade 3 in controls. There was an increasing trend of apoptotic index (AI) seen in TH-treated groups with increasing dosage of Tualang Honey, however, the mean AI values of all TH-treated groups were not significantly different from the Control value (p>0.05). In conclusion, Tualang Honey exerted positive modulation effects on DMBA-induced breast cancers in rats in this preliminary study.

Planner configuration thin film solar cells (TFSCs) with SnS/CdS heterojunction performed a lower short-circuit current (J_SC). In this study, we have demonstrated a path to overcome deficiency in J_SC by the incorporation of Se in the SnS absorber. We carried out the incorporation of Se in VTD grown SnS absorber by rapid thermal annealing (RTA). The diffusion of Se is mostly governed by RTA temperature (T_RTA), also it is observed that film structure changes from cube-like to plate-like structure with T_RTA. The maximum J_SC of 23.1 mA cm^-2 was observed for 400℃ with an open-circuit voltage (V_OC) of 0.140 V for the same temperature. The highest performance of 2.21% with J_SC of 18.6 mA cm^-2, V_OC of 0.290 V, and fill factor (FF) of 40.9% is observed for a T_RTA of 300℃. In the end, we compare the device performance of Se- incorporated SnS absorber with pristine SnS absorber material, increment in J_SC is approximately 80% while a loss in V_OC of about 20% has been observed.
