  • Cold-rolled carbon steel sheets are commonly used in railroad car or commercial vehicles such as the automobile. These are mainly fabricated by spot welding which is a kind of electric resistance welding. But fatigue strength of spot welding joint is lower than that of base metal due to high stress concentration at nugget edge of the spot welded part. And fatigue strength of them is especially influenced by not only geometrical and mechanical factors but also welding conditions of the spot welded joint. So for fatigue design of gas welded joints such as TS-type joints, it is necessary to obtain design information on stress distribution at the weldment as well as fatigue strength of spot welded joints. And also, the influence of the geometrical parameters of spot welded joints on stress distribution and fatigue strength must be evaluated. And analysis approach for fatigue test using design of experiment are evaluated optimum factor in TS-type welded joint and geometrical parameters of materials. Using these results, that factors applied to fundamental information for automation of fatigue design.

  • The choice of strain, substrate, and environmental conditions are fundamental factors that determine the ability of a fungus to develop and produce mushrooms with high quality. The objective of this study was to compare the strains of Lentinula edodes and Ganoderma lucidum originated from South Korea and Brazil in relation to their vegetative development in different culture media, to obtain isolates with high quality. The strains of the two mushroom species from Brazil and South Korea grew slowly, possibly because of abiotic factors or storage technique used. However, it may be concluded that temperature, humidity, light, pH, and nutrients from the substrate, if not regulated appropriately may affect the vegetative species.

  • These days Women have repented their past when they were inactive in attaining their own rights and they've payed attentions in gaining their fundamental rights, especially health rights. The spread of contraception use is important to fulfill women's health right. There are a lot of meanings in the contraception use. It makes women can control their reproductive activities such as pregnancy, delivery, and raising children etc. It gives each woman has autonomy of her life. The review reveals high contraceptive rate and high experienced artificial abortion rate in Korea. It means Korean married couples use contraception inefficiently. From 1970's to 1980's, most of the researches in contraceptions were descriptive and survey studies. Since 1990's, the studies have researched in the feministic perspectives. In order to understand experiences of contraceptive behaviors, qualitative researches through indepth interview did. But the number of researches were limited. The relating factors to contraceptive behavior are knowledge, communication between couples, efficiency of contraceptives, self efficacy, attitudes toward contraception, national policy, mass media, public opinion, age, parity, abortion history, ever-used contraceptive method and educational level. Theses factors affect contraception directly and indirectly. Therefore. researches about contraceptives in the future must focus on development of contraceptive behavior assessment tools and further study should be comprehensive and multidementional.

  • There are millions of deaths from cancer worldwide every year. Among them, 4~10% are considered to be attributable to occupational factors and 0.6 million workers die annually from work-related cancers. Occupational cancers are relatively preventable compared with the cancers associated with other factors. In the developed countries, especially in Europe, there have been hundreds of occupational cancers reported annually in the respective nation-states. However, there were only 35 cases reported in Korea in the 1990s which were accepted as being work-related cancers. This difference might be related to a low level of recognition, detection, and acceptance of occupational cancer and carcinogens in Korea. To prevent the risk of exposure to carcinogens a comprehensive list of carcinogens must be prepared. This should be followed by timely dissemination of information which will enable fundamental controls to be implemented, such as the imposition of ban, substitution, and engineering controls. This will require setting up procedures to record the past use and exposure data and carrying out robust statistical analyses of that data on occupational cancers and carcinogens.

  • To evaluate the total quality activities is the most fundamental and critical process as one of the PDCA cycle. The quality award criteria such as Malcolm Baldrige National Quality Award and Deming Award can be a, pp.ied to the guideline for evaluating quality activities. We can identify several important factors for TQM by referring quality award criteria, but they don't suggest how efficiently implement TQM. In this paper, two methodologies are a, pp.ied to evaluate the TQM activities comparatively. One of them is the traditional scoring system (TSS) by analytic hierarchy process (AHP). TSS is the system which evaluates the performance of TQM by the weighted sum of critical success factors. Several quality award system are typical examples of TSS. The other is the efficiency measuring system (EMS) by data envelop analysis (DEA). DEA outperformed other alternative methods to measure the efficiency and it can be a, pp.ied to evaluate the TQM activities. The evaluation system by DEA can be named as EMS. The objective of this paper is to suggest a model called TAE (Total quality management Activities Evaluation), for evaluating TQM activities. In this model TQM organizations are classified into four types by considering TSS and EMS. Those types are high weighted sum and high efficiency type, high weighted sum and low efficiency type, low weighted sum and high efficiency type, and low weighted sum and low efficiency type. Therefore TQM organizations must not only make efforts to get the higher scores in terms of TSS, but also take necessary steps to enhance their efficiencies.

  • It is essential to control noise and vibration in various industrial fields. In the automobile industry, various plastics have been developed and replaced metallic materials in order to reduce mass and vibration effectively. In this study, we measured and analyzed the Young's moduli and the loss factors of Acrylonitrile butadiene styrene(ABS) and Polypropylene(PP). In order to solve the fundamental error to determine the two quantities, a loudspeaker was used instead of conventional electromagnetic devices to generate bending motion to the specimens and a laser vibrometer was also used in detection of vibration signal of the specimen. The measured Young's moduli and loss factors of the ABS specimen were nearly constant as the temperature($-10{\sim}60^{\circ}C$) was increased. The loss factor of PP specimen showed peak value at $20^{\circ}C$ and it means that there is glass transition for the PP specimen. Young's modulus of PP specimen was linearly decreased as the temperature was increased.

  • A separate and distinct interaction with both the actual e-vendor and with its IT web site interface is at the heart of online shopping. Previous research has established, accordingly, that online purchase intention is the product of customer assessments of IT itself, specifically its perceived usefulness and ease-of-use(TAM). Since perceived usefulness and perceived ease of use are such a fundamental driver of usage intentions, it is important to understand the determinants of this construct and how their influence changes over the voluntariness towards the usage intention. The reason for voluntariness as a moderating variable is that it had the serious effect to the motivating in the making willingness of the internet shopping-mall usage. A better understanding of the determinants of perceived usefulness and perceived ease of use to the usage intention would enable us to design web site interventions that would increase user acceptance and usage of internet shopping-mall. Therefore, the goal of the present research is to extend TAM to include additional key determinants of TAM and to understand how the effects of these determinants change with the voluntariness of the usage intention of the internet shopping-mall.
