  • The main objective of this study was to develop a basic information base on Chinese consumers related to clothing purchases. Previous studies on Chinese consumers were extensively reviewed and in-depth interviews were conducted with 12 middle-level managers at Korean apparel companies which market their merchandises in China. Combined results from the reviews on previous studies and interviews indicated that traditional values, communism and industrialization are the major forces which shape contemporary Chinese consumers. Industrialization, in particular, accompanied by influx of western culture and economic development, has resulted in wide-spread phenomenon of conspicuous consumption. Thus, brand and brand images appeared to be the most important considerations for purchasing imported apparels. In addition, diversity of Chinese consumers and geographical differences were emphasized, which indicated need for market segmentation. Other characteristics including body measurements also provided implications for fashion marketing in China.

  • Plasma process has great possibilities to remove SOx, NOx simultaneously with high treatment efficiency and is expected to be suitable for small or middle plants. It was accomplished to evaluate SO2, NOx control possibility and achieve basic data to control pollutants by use of Surface Discharge Induced Plasma Chemical Process (SPCP) in this study. O3 generation characteristics by discharge of a plate was proportional to O2 concentration and power consumption and inversely proportional to temperature and humidity, In case of dry air, NOx was highly generated by N2 and O2 in air during the plasma discharge process but it was decreased considerably as H2O was added. SO2 removal efficiency was very high, and removal rate was 170,350 mEA at 30,50 watt respectively in flue gas which is usually contain HIO. NOx removal efficiency was about 57% at 40 watt power consumption with 7.5% humidity. It is estimated that H2O has an important role in reaction mechanism with pollutants according to plasma discharge.

  • A study on swirl chamber for diesel engine is to realize lower fuel consumption and exhaust emission than the current marketing engines. Author formerly reported the performance characteristics of small IDI diesel engine with swirl chamber by changing the jet passage area and its angle, and the depth and shape of the piston top cavity. Following after the first report, in this paper, the characteristics of fuel consumption, soot emission, and exhaust gas temperature were examined and analyzed after dimension of jet passage area expanded to $70.1mm^2$ The results were that the optimum values of the jet passage area depending on the depth of the piston top cavity were different at each engine speeds and loads, and in accordance with application of engine running conditions they were able to be selected as optimum dimensions of each design parameters.

  • Aluminum films were chemically vapor deposited for the metallization of the integrated circuits and the spiking characteristics of the direct CVD Al/Si contacts were investigated. When the aluminum was formed by CVD uniform consumption of the substrate silicon was observed, which is quite different from the phenomena observed in sprttered Al. Silicon consumption occured during the deposition of CVD Al and the erosion depth of the silicon was several hundred $\AA$ when the continuous films were formed on the substrate while much less erosion of the silicon occured when the Al were formed in islands. When the submicron contacts were selectively plugged, contact resistances were very low and the erosion depth of the silicon was trivial.

  • This paper presents the performance and emissions characteristics of a small spark-ignited gasoline engine. The engine used in this paper is a single cylinder, diaphragm carburetor, two-stroke, air-cooled 26cc SI engine for brush cutter. For the performance of the engine, RPM, torque, and fuel consumption were measured and HC, CO, and NOx measured for the emissions according to the change of the dynamometer load at wide open throttle (WOT) position. The results showed that the excess air ratio decreased and torque increased with increasing loads, the torque and brake specific fuel consumption were the optimum driving condition at the 7000 rpm, HC and CO emissions increased with increasing loads and with an decrease in excess air ratio over 7000 rpm.

  • Recently, some major environmental problems are the increase of fossil fuel price and $CO_2$ emission. To solve these problems, it is imperative to develop eco-friendly techniques and to reduce energy consumption in apartment complexes. Therefore, an effective system for insulation needs to be developed to reduce energy consumption. This study compares thermal characteristics between general insulation and super insulation Vacuum Panel, which is thinner and has more insulation efficiency.

  • Low temperature vacuum drying technique shows very excellent energy efficiency and prominent drying performances compared with the conventional hot air drying technique. This study was focused on the thermal characteristics of the low temperature vacuum drying technique. From the results of this study, it was confirmed that the time consumption for drying with the new drying technique could be shortened to about 1/3 of the time consumption with the conventional hot air drying technique under the same drying conditions for wet products. Also, the maximum drying rate with the new drying technique reached to about $0.35kg/m^2h$ at about 400% of moisture content.

  • The spray models incorporated into the GTT code were tested for free spray, spray in swirling flows and the sprays impinging on a flat wall. And the validity of the models has been confirmed by comparing the calculated results with the experimental data. Using this code, the spray behavior in the diesel combustion chamber have been numerically analyzed for variation of nozzle diameter. Also, the effects of nozzle diameter in diesel combustion was investigated experimentally by measuring the performance in a D.I engine. This study provides the information for the spray characteristics and emissions with variation of nozzle diameter. As a result, it has shown that decreasing nozzle diameter resulted in improving smoke and specific fuel consumption in a middle speed range.

  • The strategy that using data collection from Netflix uses for its services is different from traditional human interaction and the communication, and it is represented by the systematic algorithm that rooted from intelligent information system based on the human interaction and communication. These characteristics allowed the study to reflect the influence of 'Asset specificity' which affects the continuous consumption of the media services of Netflix users through economic psychological analysis based on transactional cost economics. The result from the survey on actual Netflix users, three types of specificity (Space specificity, time specificity, relational specificity) reduced perceived searching cost whereas perceived instrumentality has increased, eventually reinforces the commitment to the service. This implies that the service characteristics of Netflix, trying to communicate with the individuals based on intelligent information system are distinct from the existing platform services and it gives the significance of work very effective for user's continuous consumption of the media services.
