We are undertaking an extra-solar planet search around G-type giant stars by means of Doppler technique using an iodine absorption cell installed to the high dispersion echelle spectrograph for the 188 cm reflector at Okayama Astrophysical Observatory (Okayama Planet Search Program, OPSP). Having detected the first planet candidate (Sato et al. 2003)the search has been proved very promising. Taking advantage of this success, we are trying to develop OPSP to an international collaborative work. We here report the current status of our efforts for establishing such collaborations, namely, those with Chinese and Korean astronomers. We also propose to establish an East-Asian network to search for extra-solar planets around G-type giant stars with the transit detecting technique as well as the Doppler technique, asking other persons/groups to join us to enjoy the planet search.

The introduction of coffee business means adapting new culture more than coffee business itself as you see if from the trend of brand coffee stores in Korea now days. This 'new coffee culture' is popular among the adults from university students to business people and it has settled as a trend not only for drinking coffee but also for a place where they can take a rest and enjoy the culture. For that reason the elements which organize space to space takes great deal of weight in Marketing. Customers are looking for spaces such as business room, studying room, parkinglot, smoking area and also want comfortable seats and good atmosphere. It shows how important marketing is in Space design. Following study is to study about the key space design elements which is getting luxurious and individual in brand coffee stores. The aim of this essay is to broden variety and creativity of the space design in the market from now on.

The $L_1$ regularized estimator in quantile problems conduct parameter estimation and model selection simultaneously and have been shown to enjoy nice performance. However, $L_1$ regularized estimator has a drawback: when there are several highly correlated variables, it tends to pick only a few of them. To make up for it, the proposed method adopts doubly regularized framework with the mixture of $L_1$ and $L_2$ norms. As a result, the proposed method can select significant variables and encourage the highly correlated variables to be selected together. One of the most appealing features of the new algorithm is to construct the entire solution path of doubly regularized quantile estimator. From simulations and real data analysis, we investigate its performance.

Localized communication networks for office automation, security monitoring, environmental management of buildings, computer communications, and other applications enjoy every increasing demand. This paper proposes a direct sequence spread spectrum communication system for use in power line data transmission. Advantages of power distribution circuits include reasonably universal coverage and easy access vis a standard wall plug. Disadvantages include limited communication bandwidth, relatively high noise levels, and varying levels of impedance, noise, and attenuation. Spread spectrum signalling provides immunity to narrow-band signal impairments and multiplexing capability. Our prototype power line communication module supports completely physical and data link layers based on the international standard ISO 10368 for reliable high-speed power line communication system. Moreover it provides useful functions to compose a plant monitoring and control system. All the circuits of the communication module are included in one compact circuit. Thus a functional communication system for the power line plant monitoring and control is implemented.

The purpose of this study were (1) to segment the female college students according to apparel shopping orientation and (2) to create a profile for each group with regard to impotance of store attributes, use of information sources, and self-image. The questionnaire were administered to the female college students living in Seoul and data were analyzed by frequency, percentage, factor analysis, cluster analysis, one-way ANOVA(analysis of variance), and MANOVA(multivariate analysis of variance). By cluster analysis of apparel shopping orientation factors, four groups are identified : (1) highly involved apparel shopper (44.34%), (2) brand-loyal shopper (24.43%), (3) planned / practical shopper, and (4) apathetic shopper (18.10%) Four groups were then compared through MANOVA on importance of store attributes, use of information, and self-image. Significant differences were found among four groups on three variables. In general. highly involved shopper tend not to be price conscious, enjoy shopping and use the information sources most actively and apathetic shoppers tend to be indifferent to apparel shopping and do not actively use the information sources.

The purpose of this research is to identify stereotypes toward the single women(30-49 age) held by university students. Stereotypes toward the single women were examined at two levels: to assess students' beliefs about the traits of single women and to categorize the traits into stereotypes. The main results of this study were as follows: 1) Students reported 99 traits associated with the single women. 2) Hierarchical cluster analysis of the trait groupings revealed two high-level clusters: a cluster of 45 positive traits and a cluster of 54 negative traits. Within the positive and negative clusters, 10 middle-level categories, 4 positive categories(enjoy living affluently, independence-oriented, progressive, openhearted), and 6 negative categories(lack of vitality, pitiful, self-centered, picky, childish, self-defensive) were identified. This results suggested that young adults believed negative stereotypes are more typical than positive ones.

Food is very important for human being. It is not easy for us to enjoy good life because the situation of food is not good in Korea. The self-sufficient food rate is very low and most of food which we take was produced by industrial agriculture. Food of this kind has some problems with respect to the health of consumer, agriculture, environment and community. In order to secure the true food which is safe and environmentally sound, producers, consumers and community have to work together. Producers must engage in environmental agriculture. They must produce the true food and need to know regional consumers. Consumers must pay attention to the regional agriculture and must participate the production of true food. Local government must open farmers' markets for direct marketing between farmers and consumers. NGOs should educate and organize the producers and consumers.

In this research, first of all, the special feat-ures of Haute Couture design world (1990∼1996) prevailed in Paris and Rome are investigated, and additionally the understanding of collection concept and design structure analysis are performed to show the various method-ology of creative design. Expression method and design method are the main criteria in analyzing, and the main results of this research are summarized as follows : 1. Most of designers in Paris and Rome ex-press the traditional costume style. Paris designers are focusing on the expression of design morphology through the abstraction and re-appearance without being confined to theme expression ; Rome designers are expressing their main ideas utilizing the fashion image as their theme in lieu of expressing the design morphology. 2. Most of the designers in Paris and Rome are using simple lines for their design. Paris designers prefer the plastic design based upon formal and symmetrical balance of informal and asymmetrical balance to the partial trans-formation design ; Rome designers are enjoy-ing rather the partial transformation using the detail and trimming than the plastic design.

The two-way balanced one-level rotation design, $r_1^m-r_2^{m-1}$, and the three-way balanced multi-level rotation design, $r_1^m(\iota)-r_1^{m-1}$, were discussed (Park et al., 2001, 2003). Although these rotation designs enjoy balancing properties, they have a restriction of $r_2=c{\cdot}r_1$ (c should be a integer value) which interferes with applying these designs freely to various situations. To overcome this difficulty, we extend the $r_1^m(\iota)-r_1^{m-1}$ design to new one under the most general rotation system. The new multi-level rotation design also satisfies tree-way balancing which is done on interview time, rotation group and recall time. We present the rule and rotation algorithm which guarantee the three-way balancing. In particular, we specify the necessary condition for the extended three-way balanced multi-level rotation sampling design.
