The growth of function in vehicle needs complex display and control system, the In-Vehicle Information System(IVIS). Although current IVISs are widely implemented in commercial vehicles, a new form of IVIS has been recently studied in order to reduce drivers' workloads. The purpose of this study is to suggest an appropriate menu structure of a new type IVIS, to be implemented on the instrument cluster panel, using Taguchi's parameter design. In the research, firstly, functions were selected that are appropriate to control through the instrument cluster among existing functions of current IVISs by quantitative evaluation of ergonomic principles. Then, menu structure alternatives were extracted by investigating priorities to those functions selected. Finally, menu structure alternatives were evaluated through an experiment and suggest the most appropriate one by applying Taguchi's parameter design. Taguchi method was used not only for planning an experiment but also evaluating alternatives. SN ratios were a key value to evaluate the alternatives and to find the most proper one. Through the research, the most appropriate menu structure for the instrument cluster IVIS was finally suggested among the alternatives and it is expected that the results of this research could provide a guideline to the instrument cluster IVIS.

The level of security of most sensor nodes that comprise the sensor networks is low, but because of the low computing power and small storage capacity, it is even very difficult to apply a security algorithm efficiently to the sensor nodes. Therefore, preventing the join of an illegal node to a sensor network is impossible, and the transmitting information is easily exposed and overheard when the transmitting algorithm of the sensor node is hewn. In this paper, we propose a group key management scheme for the sensor network using polar coordinates, so that the sensor nodes can deliver information securely inside a cluster and any illegal node is prevented from joining to the cluster where a sensor network is composed of many clusters. In the proposed scheme, all of the sensor nodes in a cluster set up the authentication keys based on the pivot value provided by the CH. The intensive simulations show that the proposed scheme outperforms the pair-wise scheme in terms of the secure key management and the prevention of the illegal nodes joining to the network.

The purpose of this study were to investigate the purchase influence of teenagers in the family by examining the evaluation of market value according to their clothing purchase style. The questionaire survey was carried out 572 high school, and middle school students in Seoul region in Feb., 2000. SPSS package program was used to analyze the gathered data. The results of the research were as follows: 1. Four types of family communication patterns were identified through cluster analyses: laissez-faires, protectives, pluralistics, consensuals. 2. Market values were classified into seven dimensions by factor analyses: user value-psychological value, performance value; payer value-payment convenience value, price value; buyer value-personalization value, service value, purchase convenience value. 3. Independent purchase was evaluated higher than joint purchase for the price value and psychological value, while joint purchase marked higher than independent purchase for the performance value, payment convenience value, service value and purchase convenience value. And there were some differences in the results of evaluation among the family communication patterns.

Genomic DNA isolated from two geographical populations of pond-smelt (Hypomesus nipponensis) was amplified for RAPD (randomly amplified polymorphic DNA) analysis. The populations were obtained from Chungju (CJ), in the inland area, and Dangjin (DJ), in the vicinity of the West Sea in Korea. Seven arbitrarily selected primers, OPB-06, OPB-10, OPB-13, OPB-17, OPC-09, OPC-17 and OPC-20, were used to generate the shared loci, polymorphic, and specific loci. Three hundred and eighty-three loci observed per primer were identified in the CJ population, and 287 were identified in the DJ population. Among them, 91 polymorphic loci or 23.8% were polymorphic in the CJ population, and 47 (16.4%) in the DJ population. The number of shared loci observed was 198 in the CJ population and 176 in the DJ population. Forty-four and 75 specific loci were detected in the CJ and DJ populations, respectively. Especially, 99 numbers of shared loci by the two populations, with an average of 14.1 per primer, were observed in the two pond-smelt populations. The average bandsharing value between the two geographical pond-smelt populations was $0.700{\pm}0.008$, ranging from 0.600 to 0.846. Compared separately, the bandsharing value of individuals within the CJ population was higher than that of the DJ population. The dendrogram obtained using the data from the seven primers indicated three genetic clusters: cluster 1, CJ 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, and 11; cluster 2, DJ 01, 02, 03, 04, 05, 06, 07, 08, and 09; and cluster 3, DJ 10 and 11. The genetic distance between the two geographical populations ranged from 0.040 to 0.545. Thus, RAPD-PCR analysis revealed a significant genetic distance between the two pond-smelt populations.

The purposes of this study were to reveal the relation of consumer value variables and to identify the difference of clothing information exploration behaviors on consumer value variables. The data were collected from 267 college women residing in Gwangju using a Questionnaire to general value, clothing value, consumption value and clothing information exploration behaviors. It were analyzed with factor analysis, cluster analysis, T-test, ANOVA and multiple regression analysis using statistical program SPSS 10.0. The results of this research were as follows: 1. Only one factor of general value had a significant influence on 'practical' of clothing value. All of general value and clothing value had a significant influence on the whole consumption value. 2. Clothing information search behaviors was divided into three factors: 'variety pursuit' 'active information collection' and 'uniqueness pursuit'. General value group had a significant difference in 'variety pursuit' and 'active information collection' behavior. Clothing value and consumption value group had a significant difference in all factors of clothing information search behaviors. By implication, this study could be explain each contributions of consumer values and suggest useful variable of consumer values in future clothing behaviors research.

The purpose of this study was to explore housing value clusters of young renters in South Korea and their relationships to household and housing characteristics reflected in the 2012 Korea Housing Survey (KHS). The 2012 KHS microdata was used as secondary data. Among the households included in the microdata, 1,196,144 young renter households (between 20 and 34 years of age) in private rental units were analyzed. The main findings are as follows. Ten rating scale items measured housing values. Eight of them were grouped into three value factors: Investment, Affordability and Cost Increase. Using these three value factors and perception of homeownership, households were classified into four clusters: Prospective Home Investor, Settled Renter, Homeowner Wannabe, and Support Needed. The current tenure types, income and expectation for next tenure types of four housing value clusters of young renters reflected Korea's tenure ladder which has home ownership at top followed by Jeon-se rental, monthly rental with deposit and monthly rental without deposit. The households in Prospective Home Investor and Homeowner Wannabe clusters would consider home purchase in the near future. Finally, households in Support Needed Cluster would be the main target to consider in development and implementation of housing welfare policies and programs to resolve housing problems of young renters, including beginning-stage professionals.
