Background: We have doubt about the truth that Type 2 DM is associated with chronic hepatitis C infection. The aim of our study was to prove a close relationship between chronic HCV infection and type 2 DM in korean patients. Methods: We reviewed the out-patient's medical records of 466 patients with type 2 DM who visit the Sung-ae hospital from March 2000 to August 2001. Diabetic patients were analyzed for the following variables: age, sex, waist circumference, weight, waist/hip ratio, using of self monitoring of blood glucose, method of therapy, duration of disease, experience of previous transfusion, major surgical procedure, accompanied disease, liver function tests (LFT), HbA1 c. We ruled out patients with liver cirrhosis. Results: Hepatitis C virus infection was observed more frequently in patient with Type 2 DM. Of 466 Type 2 DM patients, 13 patients were infected with Hepatitis C virus (2.79%). Compared with mean prevalence of Korean population (1.3~1.6%), it's value is very high. the other hand, 21 patients were infected with Hepatitis B virus (4.5%). Such results are similar to mean prevalence of the general public (4~5%). Conclusions: Prevalence of hepatitis C was closely associated in korean patients with type 2 DM. And an increased prevalence is independent of cirrhosis.

Results and Discussion The findings of this study were as below: 1. The General Characteristics of the Subjects : Most of the housewives investigated were in their 30s and 40s, with 41.7% and 50.8% respectively. 2. Bedroom : When it comes to bedroom style, 47.8% put beds in their rooms with the Korean under-floor heating system, and 45.4% didn`t place beds in their rooms with the same heating system. 3. The Purchase of Bedding : 49.0%, approximately half the homemakers, bought their current bed- clothes at bedding shops, and just 3.2% made them on their own at home. 4. The Use of Bedclothes : In summer, yam (flax, ramie fabric) and a single-layer bed sheet (41.9%) were in use most, followed by a single-layer quilt (34.5%). 5. Bedding Management The most common frequency of bedding disinfection by sunning was once a month (29.4%), followed by once per two weeks (23.9%) and once a week (19.0%) in the order named. nThe purpose of this study is to grasp the actual condition toward the clothing of senior males` and perception of male`s formal wear companies for silver market through a survey targeting senior males and clothing companies. The survey was conducted targeting 196 senior males and chief-patterners of 7 companies` 10 brands. The questionnaire distributed to senior males was consisted of 22 items regarding the perception and satisfaction on clothes. And 12 items concerning the perception of senior male clothing brands and the size system was developed for clothing companies. The results of the study are as follows. The study revealed that most senior males perceived that brand clothing for them was necessary. More than half of the respondents were not satisfied with ready-made clothes. And many senior males prefer ready-made clothing when they purchase their clothes. For these reasons, senior males apparel market might be promising. Currently, the perception of male`s formal wear companies on the need of brand was high. However, considering that brand launching might be difficult to be realized soon I presume that size spectrum based on body size of senior males is necessary which reflect their physical characteristics and activities.

There are various ways to operate traffic light system by varying the operational speed of the system. One of the solutions is to vary the length of the clock cycle of the system. It is difficult to vary the length of the signal in systems by varying the period of the clock cycle and nor it is a generalized technology in the current traffic systems. The traffic signal systems of the past used is simply a repetitive traffic signal system which traffic period is consistent, not considering the conditions of traffics. The system that will be introduced in this thesis could substantially improve efficiency of traffic flows by varying the length of traffic signal period with sensors which detect the presence of vehicles on both directions and allows the signal continuously on the direction where there are more waiting vehicles, and even skips the signal where there is no vehicle waiting. In this thesis, it introduces the methodology of detecting the spots that is detected by the sensors of the system and outputs green light in due order in accordance with the priority given to the system. In the meanwhile, the ratio of yellow light and green light is designed to be 1 to 8 in the way that maximizes the efficiency of traffic flows.

成秀光 대구효성가톨릭대학교 1993 연구논문집 Vol.47 No.1

Sleeping is important for human being in that it has a great effect on their daily activities. considering that an average adult sleeps seven to eight hours a day, a third of our life is spent in bed. Just a sresearch on the enviorment and clotyin gin the daytime life is important, so are the studies on the sleeping environment and bedding. The presesnt study intends to make consumers aware of the important of the bedding science and help the manufacturers develop efficient, up-to-date beds. For these two purposes, consumers' recognitions and opinions on the features of the bedding they sleep in were surveyed, and also experiments were conducted to find out the thermal features of bedding required for pleasant sleeping. In the study, a questionsire consisting of various items on the fearures of bedding was designed and distributed randomly to consumers in Korea to survey the patterns in which they but, use and maintain their beddings. Their answers on each item were analyzed to find out the differences in the patterns and opinions that appears according to the age. And a comparative study of the findings was performed with the Japanses ones. The results of the sutyd are as follows. The important points tto be considered for purchasing bedding are air permeability, humidity absorption and thermal insulation. It means that the consumer regard the function of the product as important, but thermalinsulation, air permeability and heaviness cause dissatisfaction from the use of bedding. Most of subjest enjoy their sleeping life by using traditional cotton quit, but many of them hope to purchasen silk, wool and down/feather quilt, and the main sleeping life of the cosumer is of Korean style, while that of younger generation changes gradually into weatern one, showing their individuality and varety. The use of heater and air conditioner in the bedroom means the relative lowering the rate of attaching the importance to the function of bedding. And also, this study shows a similar trend towards the importance and dissatisfaction of bedding, and the perception of the bedding of younger generation between both in Korea and in Japan.

In this paper, the fabrics for Korean folk clothes(KFC) undergoes repeated laundering under given condition. After this cyclic laundering was applied, the mechanical properties of the specimen were measured using KES-F system in order to evaluated the end-use performance of fabrics for KFC. And also, the crease recovery of fabrics for KFC were measured by shirley crease recovery tester. 78 different kinds of commercial silk fabrics and polyester fabrics for KFC were used for this study. The experimental results were analysed statistically to relate the mechanical properties and the crease recovery of fabrics for KFC. Furthermore, these changes in dimensional stability, mechanical properties and handle of fabrics for KFC were discussed in comparison with those values for silk fabrics and polyester fabrics. The results obtained are as follows. 1. Regardless of materials, remarkable increase are observed in shrinkage of the fabrics for KFC about repeated laundering, but dull increase are observed in shrinkage after 10 cycles of the repeated laundering. On the other hand, slack extend are observed in dimensions after 20 cycles of the repeated laundering. The shrinkage of fabrics for KFC after 10 cycles of the lundering showed that the silk fabrics are 1.74±0.33% (warp direction) and 1.35±0.23% (weft direction) and the polyester fabrics are 1.45±0.22% (warp direction) and 1.25±0.23% (weft direction). 2. Except for tensile property, these changes in mechanical properties of fabrics for KFC by laundering have ±16 range of bending, shearing, compression, surface, thickness & weight as compared with before laundering. Particularly, the LT and RT about 1∼3 cycles of the repeated laundering showed remarkable decrease. And SMD, WC, T & W of fabrics for KFC by the laundering were more increased than one for original fabrics. But B, 2HB, G, 2HG, 2HG5 were decreased more than one for original fabrics. 3. "Stiffness", "Anti-drape", "Crispness" and "Scroop" hand values decrease and"Fullness & softness", "Flexibility & softness" hand values increase with repeated laundering. 4. Remarkable decrease are observed in crease recoveries about 1∼5 cycles of the repeated lundering, but slack decrease are observed in crease recoveries after 5 cycles of repeated laundering. The crease recovery of fabrics for KFC have negative(-) correlation with LT, RT, G, RC and MMD, This fact implies that the smaller these values, the larger the crease recovery. The crease recovery of fabrics for KFC has a high degree of correlation with the mechanical properties such as shearing, compression, surface property. And also, the crease recovery are expected by measuring the mechanical properties such as G, 2HG, 2HG5, RC, WC, LC, MIU, MMD and SMD, according to the obtained regression equation.
