This study compared and analyzed current sleeve head products for men and women to develop sleeve head products for aesthetically-designed sleeves. Men and women's sleeve head products, suitable for sleeve caps, were designed and developed based on the results. The study results are as follows. First, men and women's sleeve heads for aesthetic jacket sleeves were designed with sleeve patterns in the background. Sleeve heads and upper sleeves were additionally designed to make 7-layers for men and 4-layers for women. Second, sleeve head patterns were designed so that men's would have a whole length of 48cm, an angle of $30^{\circ}$ and a width of 4.5-7.5cm; in addition, women's would be 40cm, $30^{\circ}$ and 4-5cm. Third, the same materials were used for men's and women's sleeve head products, and the background was made from 1-layer of soft non-woven fabric. As for the sleeve heads, 2-layers and 1-layer of non-fusible interlinings were used for men's and women's, respectively. In order to provide flexibility, the materials were designed in a bias direction. For upper sleeves, 1-layer of non-woven fabric and felt were used for men's, and 1-layer of felt for women's so that an empty space caused by easing contraction can be supplemented.

The treatment planning and dosimetry of small fields for stereotactic radiosurgery with 10 MV x-ray isocentrically mounted linear accelerator is presented. Special consideration in this study was given to the variation of absorbed dose with field size, the central axis percent depth doses and the combined moving beam dose distribution. The collimator scatter correction factors of small fields $(1\times1\~3\times3cm^2)$ were measured with ion chamber at a target chamber distance of 300cm where the projected fields were larger than the polystyrene buildup caps and it was calibrated with the tissue equivalent solid state detectors of small size (TLD, PLD, ESR and semiconductors). The central axis percent depth doses for $1\timesl\;and\;3\times3cm^2$ fields could be derived with the same acuracy by interpolating between measured values for larger fields and calculated zero area data, and it was also calibrated with semiconductor detectors. The agreement between experimental and calculated data was found to be under $2\%$ within the fields. The three dimensional dose planning of stereotactic focusing irradiation on small size tumor regions was performed with dose planning computer system (Therac 2300) and was verified with film dosimetry. The more the number of strips and the wider the angle of arc rotation, the larger were the dose delivered on tumor and the less the dose to surrounding the normal tissues. The circular cone, we designed, improves the alignment, minimizes the penumbra of the beam and formats ball shape of treatment area without stellate patterns. These dosimetric techniques can provide adequate physics background for stereotactic radiosurgery with small radiation fields and 10MV x-ray beam.

The numerical simulation of heavy precipitation event occurred in the central Korean Peninsula on July 26-28, 1996 was performed using the fine mesh model. ARPS (Advanced Regional Prediction System) developed by the CAPS (Center for Analysis and Prediction of Storms). Usually, the heavy rainfalls occurred at late July in the Korean Peninsula were difficult to predict, and showed very strong rainfall intensity. As results, they caused a great loss of life and property. As it usual, this case was unsuccessful to predict the location of rain band and the precipitation intensity with the coarse-mesh model. The same case was, however, simulated well with fine-mesh storm-scale model, ARPS. Moisture band at 850 hPa appeared along the Changma Front in the area of China through central Korea passed Yellow Sea. Also the low-level jet at 700 hPa existed in the Yellow Sea through central Korea and they together offered favorable condition to induce heavy rainfall in that area. The convective activities developed to a meso-scale convective system were observed at near the Yangtze River and moved to the central Korean Peninsula. Furthermore, the intrusion of warm and moist air, origninated from typhoon, into the Asia Continent might result in heavy rainfall formation through redistribution of moisture and heat. In the vertical circulation, the heavy rainfall was formed between the upper- and low-level jets, especially, the entrance region of the upper-level jet above the exit the region of the low-level jet. The low level convergence, the upper level divergence and the strong vertical wind were organized to the very north of the low level jet and concentrated on tens to hundreds km horizontal distance. These result represent the upper- and low-level jets are one of the most important reasons on the formation of heavy precipitation.

This study empirically examined Seo Yu-gu's views on constumes that are based on 'Boksikjigu[服飾之具]' of Seomyongji[贍用志] in Imwonkyungjeji[林園經濟志]. In 'Boksikjigu', Seo Yu-gu explained different situations and problems that were related to costumes and proposed solutions for the problems. This study examined the contents, and divide the items into caps, accessories, and clothes. The results of this study were as follows. First, Seo Yu-gu in he rited the tradition of erudition. Seo Yu-gu classified various costume items systematically, and explained in detail about the origin, history and materials of the costume items. Second, he emphasized frugality, effective use, and welfare. Seo Yu-gu argued that the sleeves should be shortened for convenience and tried to improve practicality in the functional aspect. Also, he wanted to enrich people's life by improving the convenience of goods used in daily life. Third, he tried to establish identity as a Confucian intellect. This idea was clearly shown in 'costumes'; therefore, they served as evidences that Seo Yu-gu used to correct wrong practices through precise historical investigation and review of Shim-ui[深衣], the symbol of the practice of Jujagarye[朱子家禮]. In his later years, he discovered the plain dress that was worn as a casual wear by ZhuXi[朱熹]and tried to wear it in dailylife.

This study focuses on the hats in the advertisements of the newspapers from the Greater Korean Empire to the Time of Independence. There were Yeomo(禮帽), Jungsanmoja(中山帽子), Jungjeolmoja(中折帽子), Women's hat, Undongmoja(運動帽子), and Hakdomoja(學徒帽子) from 1897 to the 1900s. The names of the hats were written with Chinese characters as there was no specific name for women's hats. There were a lot of hats in the 1910s; Jungjeolmoja, Jungsanmoja, Hukyeomoja(黑禮帽子), Panama, Doriuchi(鳥打;とり-うち), Maggomo(麥程帽), Ilkyomoja(一交字帽), cheongyeonmo(靑年帽), Jajacheongyeonmo(刺子靑年帽), Hakaaksangmo(學生帽), Undongmo, Laparyunmoja, Banghanmo(防寒帽), Mokchulmo(目出帽), Pungbangi(風防耳), Nambaui, and Pungdongi(風憧耳). Most of the hats were western hats for men. From the 1920s to 1930s, the hats were classified as to the shape and uses as compared to before that period. The hats were advertised in the newspapers such as Jungjeolmoja, Jungsanmoja, Panama, Doriuchimo, Maggomo, Ilkyomoja, cheongyeonmo, Jajacheongyeonmo, Hakaaksangmo, Undongmo, Banghanmo, Mokchulmo(目出帽), Adongmokchulmo(兒童目出帽), Pungdongi, and Pungchasamsangun(風遮三山巾). There is little information about hats from the late 1930s to the time of independence because of the censorship of the press. The hats during that period were almost the same as the before that time. There was a new name of a cap, Jeontumoja(戰鬪帽子) which was for a soldier. The hats in that period were one of the westernized items with shoes before the westernization of the Korean costume under Japanese imperialism. Furthermore, the western hats could be spread by the men who were in the center of the society. On the other hand, women's western hats were not common because women had rarely worn them before that period. They just wore traditional winter caps steadily.

Background: There is an established link between obesity related metabolic derangement and colorectal cancer development. Recently, we developed a metabolic-colorectal cancer risk score. In this follow-up study, we studied its association with colorectal neoplasm by measuring two major metabolic syndrome biomarkers, leptin and adiponectin. Objectives: To evaluate the serum levels of leptin and adiponectin in patients with colorectal polyps and colorectal cancer and to determine any correlation with metabolic risk score. Results: In total, 130 individuals were studied: 30 controls without colonic pathology, 18 with colonic adenoma (CAP), and 82 with colorectal adenocarcinoma (CRC, 17 cases of T1-2 and 65 cases of T3-4). The metabolic risk scores in CAP and T1-2 CRC were higher than those in the controls and T3-4 CRC cases. There were no statistically significant differences in leptin levels among CAPs, CRCs, and controls. Both leptin and adiponectin levels reflected differences in body mass index and metabolic risk scores. Cases in the CAP group and early T-stage CRC groups had lower adiponectin levels (14.03 and 13.01 mg/ml, respectively) than the no polyps group (19.5mg/ml, p = 0.03). The average serum adiponectin level in the invasive cancer group (18.5 ng/ml) was comparable with that of the control group. Conclusions: The level of serum adiponectin was positively correlated with the metabolic risk score. Decreased serum adiponectin was significantly associated with the development of colorectal adenoma and early stage colorectal carcinoma.

An air filter is a device to remove dust from the air supplied to the automotive engine. A requirement for the optimum air filter is to improve the capability to remove particles from the air it takes in, that is the efficiency and amount of dust collection. By removing dust from the air, the air filter prevents the engine cylinder from wear, reduces ventilation resistance, and thus improves engine output and guarantees intake performance. In order to guarantee such air filter performance, it is very important to properly seal the air filter. For passenger cars made in Korea, the air filters are fabricated with steel caps as their frames are large and their engine capacity is big. Recently however, European countries and Japan started using urethane for manufacturing the air filter, so that all foreign-made cars now have urethane filters. The urethanes used for air filters are applied in two ways: One is to use soft urethane for both top and bottom of the air filter and the other is to use soft urethane for the top and hard urethane for the bottom. Each of these method has unique problems. In this study, hard urethane is used for both top and bottom of the filter in order to improve those problems and increase the sealing efficiency. Especially for the top, NBR (rubber mold) is pre-settled in tough urethane and then the urethane is solidified through foaming, which makes it possible to develop a solid and double-sealed filter.
