  • The artificial lung is a device used to replace the function of the lungs. The major function of the lung is to remove carbon dioxide from the venous blood and replace it with oxygen, or arterialize the blood. And the function of the artificial lung is to provide an adequate amount of oxygenated blood to all the tissues of body during the open heart surgery. Extracorporeal life support(ECLS or ECMO) is standard treatment for severe respiratory failure but poses many contributions to future lung transplantation. Artificial Lung or membrane oxygenators available today, based on microporous polypropylene fibers, are associated with two major problems. They require systemic anticoagulation of the patient and they allow serum leakage across the membrane from the blood side to the gas side during long-term use. We obtained newly fabricated polypropylene(PP)/polydimethylsiloxane(PDMS) membranes which combined PP membrane, a microporous support layer with PDMS, and we had investiaged a technique for minimizing serum lekage of polypropylene(PP) membrane. The gas permeability of each PP/PDMS membrane was almost constant before and after the whole blood test by Lee-White method, while that of PP membrane was significantly reduced. Therefore the PP/PDMS membrane could be prevented serum leakage of PP membrane. In addition, the gas permeability of $CO_2$ in PP/PDMS membrane was 11.5 times higher as compared with that of $O_2$.

  • This study investigates the disposal of clothing and the purchasing behavior and usage of environmentally friendly clothing. After compiling data from 500 consumers who reside in Seoul, it was analyzed by ANOVA, t-test, Chi-square, and multiple regression analysis. The behavioral score for buying environmentally friendly clothing was lower than the average value of the three. The lowest value was for the purchase of used clothing, but the purchase of environmentally friendly clothing was also shown to have a low value. For the usage and disposal of clothing, unused clothing, which was mostly just left in dresser drawers, was the most preferable method. Also, exchange or resale via anInternet mall was shown to be lower than the other methods. The analysis between clothing purchase and usage as well as the disposal of clothing with socio-demographics, consumption tendencies, opinions of friends and groups, commercials and advertisements, and environmental perceptions points out differences among groups. There are statistically significant differences in the purchasing intentions of slow fashion according to socio-demographics. Female consumers between $20{\sim}25$ years of age were more likely to purchase slow fashion clothing. Consumers with a high consumption tendency who were highly influenced by commercials, friends, and groups were more likely to purchase slow fashion clothing. The influence of the average clothing expenditure on an environmentally friendly purchasing behavior and the influence of the age group on repairing and usagewas the most effective. All in all, contribution to an environmentally friendly perception was the most effective variable.

  • Railway rail fastening system is the critical device which gives big influences to not only the vehicle driving stability and the orbit's structural stability against the impulsive load, but also the noise vibration and the ride comfort. As a part of the low-carbon green growth, the importance of the railroad industry is getting highlights on its excellent energy-efficiency and eco-friendliness. However, so far the Korea's domestic rail fastening system technology is not so good and the technical reliance to abroad is very heavy. In this study, we conducted comparative analysis on the rail fastening system with new and used one of the same type. And those systems are imported by Seoul Metro and are being used by it. With this basis, we developed the components and the materials and then, established the durability assessment methods appropriate to the Korean domestic circumstances. And through the reliability qualification test on the 7 parts of the rail fastening system, we've improved the reliability and guaranteed the 15 years of service lifetime. ($B_{10}Life15$) Establishment and standardization of Reliability Standard on the parts of the rail fastening system such as anti-vibration pads, guide-plate, screw spike made it possible to perform the internationally fair assessment. And it is thought that we can satisfy the manufactures' and consumers' needs of cost-cutting and qualification security by shortening of assessment period on rail fastening system.

  • Objective: This study developed a new shower carrier prototype to reduce caregivers' muscle burden and to increase use convenience by reflecting the needs of domestic long-term care institutions. Background: In the long-term care institutions, one of the ADL(Activities of Daily Life) factors is bathing/showering. Recently, bath/shower-assisting equipment is actively being introduced in care institutions to reduce the caregivers' care cost, but most of the domestic equipment was designed to imitate foreign products and rarely reflected the needs of care institutions. Method: Based on Korean elderly people's body information, the bed size(length: 1,900mm, width: 650mm) was set-up, and a variable headrest with a newly designed headform was developed to provide the comfort for the elderly and convenience for caregivers. To reduce caregivers' muscle burden on transferring and showering activities, a 3-step column lifting module equipped with dual actuators(lowest/highest levels from the ground: 600/1,100mm, Stroke: 500mm) was developed, and the wheelbase parameter(length: 1,250mm, width: 580mm) was defined securing the turn-over safety of the shower carrier. The drivability tests were performed for the prototype and foreign product, and the male and female subject's muscle activities were measured through the tests. Results: The structural stability of the shower carrier prototype was secured by finite element analysis, and the muscle activities of the subjects through the drivability tests largely decreased in the prototype, compared to the foreign product. Conclusion: In this study, a new shower carrier prototype was developed to possibly reduce caregivers' muscle burden and to increase use convenience based on the needs of long-term care institutions. It was expected that the drivability performance of the prototype could be relatively superior to that of the foreign product. Application: The results obtained from the study can be applied for the optimal development of a shower carrier including other equipment to effectively care for the elderly.

  • Purpose: The purpose of this study was to identify effects of pelvic floor muscle exercise on sexual function and to present basic information on promoting sexual function for employed middle-aged women. Method: Data were collected from July to September, 2005 from a sample of 25 conveniently selected middle-aged working women from B city. For personal reasons, 10 dropped out, leaving 15 women who were treated with the exercise for 6 weeks. Outcome measures on sexual function were assessed by a self-report questionnaire based on the Female Sexual Function Index(Rosen et al, 2000 and translated by Kim, 2004). Cronbach ${\alpha}'s $ for the two studies were .82 and .96 respectively and for this study, .81. Descriptive statistics and Wilcoxon signed rank test were used to analyze the data. Results: The mean score for sexual function was 21.42(range 2-36). There were significant improvements in total sexual function, and 4 sub-scales of sexual function, sexual arousal, vaginal lubrication, orgasm, and coital pain. No significant improvements in sexual desire or sexual satisfaction were found. Conclusion: The small sample means findings must be interpreted with caution, but do suggest that pelvic floor muscle exercise could be an effective exercise for improvement of sexual function.

  • Mankind is enjoying a great convenience of their life by the rapid growth of secondary industry since the Industrial Revolution and it is possible due to the invention of huge power such as engine. The automobile which plays the important role of industrial development and human movement is powered by the Engine Module, and especially Diesel engine is widely used because of mechanical durability and energy efficiency. The main work mechanism of the Diesel engine is composed of inhalation of the organic material (coal, oil, etc.), combustion, explosion and exhaust Cycle process then the carbon compound emissions during the last exhaust process are essential which is known as the major causes of air pollution issues in recent years. In particular, COx, called carbon oxide compound which is composed of a very small size of the particles from several ten to hundred nano meter and they exist as a suspension in the atmosphere. These Diesel particles can be accumulated at the respiratory organs and cause many serious diseases. In order to compensate for the weak point of such a Diesel Engine, the DPF(Diesel Particulate Filter) post-cleaning equipment has been used and it mainly consists of ceramic materials(SiC, Cordierite etc) because of the necessity for the engine system durability on the exposure of high temperature, high pressure and chemical harsh environmental. Ceramic Material filter, but it remains a lot of problems yet, such as limitations of collecting very small particles below micro size, high cost due to difficulties of manufacturing process and low fuel consumption efficiency due to back pressure increase by the small pore structure. This study is to test the possibility of new structure by direct infiltration of SiC Whisker on Carbon felt as the next generation filter and this new filter is expected to improve the above various problems of the Ceramic DPF currently in use and reduction of the cost simultaneously. In this experiment, non-catalytic VS CVD (Vapor-Solid Chemical Vaporized Deposition) system was adopted to keep high mechanical properties of SiC and MTS (Methyl-Trichloro-Silane) gas used as source and H2 gas used as dilute gas. From this, the suitable whisker growth for high performance filter was observed depending on each deposition conditions change (input gas ratio, temperature, mass flow rate etc.).
