Current information storage devices read/write data on the rotating disk. The axial vibration of a rotating disk should be suppressed for the successful operation of the device. Information storage devices widely used in these days adopt relatively thick disk which is stiff enough to suppress axial vibration under allowable limit. However, the thickness of the disk is going to be thinner and thinner as the small form factor of the devices is getting preferred by the consumer. In this study, a stabilizer system, which is composed with 8 air bearings, is proposed for suppressing the axial vibration of a $95{\mu}m$ thick PC disk in a non-contacting manner. The performance of the stabilizer system is simulated by numerical computation and then confirmed its results through a series of experiment. A thin and flexible disk has various vibration modes when it rotates in high speed. The stabilizer system generates positive as well as negative pressure due to the rotation of flexible disk so that the force due to the pressure distribution pushes and pulls rotating disk in a non-contacting manner. The balance between positive and negative pressure forces can be obtained by adjusting the area and the slope of the air bearing surface. The axial vibration of the flexible disk of 120mm diameter is suppressed successfully from over $1000{\mu}m$ to $30{\mu}m$ peak-to-peak value at the rotational speed of 5,000rpm.

The purposes of this study were to investigate demographic profiles between the consumer group under high time pressure(HTP) and the group under low time pressure(LTP) during the shopping, to examine the level of association between the fashion information sources and time pressure variable, to determine the difference in clothing benefits sought between HTP and LTP, and to determine the difference in purchase criteria. We distributed questionnaires to 600 women aged in 20-65. The reliable 562 questionnaires were used for a statistical analysis. Data analyses were conducted with SPSS program on t-test, cluster analysis, factor analysis, and Chi square test. We obtained the following results: There was a significant association between demographic variables such as age, occupation, education, residence area, & family cycle and time pressure variable. Fashion information sources were classified into 4 factors. HTP searched information on fashion products using more various sources than LTP did. There was also a significant difference between HTP and LTP in clothing benefit sought. Four clothing benefit factors such as trendy/social position, economic value, protection/comfort, and makeup of body shape were sought more by HTP than by LTP. In addition, HTP considered significantly more purchase criteria such as color/pattern, comfort, quality, suitability, material, sewing finishing, coordination, price, brand, easy care, and country of origin than LTP.

주택시장의 패러다임이 수요자 중심의 시장으로 변화하고 있으며 이는 수요의 축소와 공급자인 건설사간의 경쟁이 심화하고 있음을 의미한다. 따라서 환경변화에 대응하기 위한 효과적인 건설사의 공동주택 공급전략이 요구되며 이는 마케팅, 상품개발, 품질관리 등의 측면에서 매우 중요한 의의가 있다. 본 연구에서는 이러한 환경변화에 대응하기 위한 건설사의 전략수립에 기초가 되는 요인을 도출하기 위하여 CS 전문가를 대상으로 공동주택을 13개 부위로 구분하여 각 부위별 마감품질의 중요도에 대한 설문을 실시하였다. AHP 기법을 활용한 분석결과 각 부위별 중요도는 주방, 세대현관, 지하주차장 등의 순으로 나타났다. 위와 같은 분석결과는 입주자를 대상으로 실시할 후속연구의 결과와 연계할 경우 건설사의 공동주택 공급전략 수립에 효과적으로 사용될 기초자료가 될 것으로 기대된다.

This study investigates the different characteristics (mainly of community life) in representative intentional communities, between the ecovillage and cohousing, since the different purpose of the establishment of the community might result different characteristics. The study method is data analysis: the analysis material is Community Directory, A Comprehensive Guide to Intentional Communities and Cooperative Living (Rutledge, 2005). Of 750 listed communities, 397 (211 ecovillages and 186 cohousings) communities were analyzed. The findings of the study reveal that there are clear differences of community life between ecovillages and cohousings even though two communities are regarded as similar intentional communities. The similarities between the two communities are as follows: 1) Those mostly distributed in the USA, and established before 2000. 2) Dominant size of intentional communities is less than 20 residents and 20 houses. 3) They make decisions in consensus. 4) They eat together very frequently; at least once a week or more. 5) Shared work is required. The differences between the two communities are as follows: 1) They have different aims of establishment. For instance, ecovillage focus more on eco-living, while cohousing focuses more on the cohousing idea. 2) There are more female residents in cohousings than in ecovillages. 3) There are more cohousings in urban areas with a smaller area of land, contrary to that there are more ecovillages in rural areas with larger areas of land. 4) There are less identified leaders or leadership core groups in cohousing than in ecovillages. 5) Income sharing is more common in ecovillages than in cohousings. According to there findings, it is evident that a different purpose of establishment result in different characteristics of community life even though those belong to the similar category of the intentional community. Thus, it is recommended to adapt the correct characteristics that fit the aim of the community in the establishment an intentional community Topics and discussions about establishing intentional Topics and discussions abut establishing intentional communities could contribute to gather the intentional communities could contribute to gather the interests communities could contribute to gather the interests of residents as well as those of relevant civil-workers and administrators in Korea.

The purpose of this study was to observe street fashion, to determine preferred design of jean and to analyze preferred jean styling based on types of jean pants design, toward 20s to 30s women. We observed outfits of jean styles on the street using photography method and conducted a survey to 400 females to get information of consumers. Four hundred questionnaires were analyzed using SPSS. As a result of street research, the majority of people were wearing jean pants with T-shirts, sandal/high heel shoes and totes. The results of market research showed that preferred jean styles were significantly associated with age and marital status. Preferred color of jean pants was also significantly associated with age variable. Current popular jean style was a skinny style. We evaluated results of styling with different jean pants, creating five different images. There was a significant relationship between age/marital status and styling image in different jean styles. In a bootcut style, age variable was significantly associated with different styling images. Generally, most of people responded cute/casual image styling was the best for the bootcut style. In skinny pants, there was a significant association between a residence area and a styling image. Modern/chic image styling with skinny pants was the most favored one. In cropped jean pants, marital status was significantly associated with styling image created. We realized that we can create different images through a styling.
