The purpose of this study were to investigate the relationships of situation variables, product variables. consumer variables and impulse buying behavior in apparel store. We collected data from 462 consumers of adult women living in Pusan and analysed by factor analysis, cluster analysis, analysis of variance, t-test and discriminant analysis. The results were as follows: First, The purchase situation influenced on the impulse buying behavior consisted of the Pre-purchase condition and the Point-of-purchase state. The in-store situation consisted of the Salesman/store atmosphere, the Low price and the Possibility of out of stock. And the consumption values of apparel are divided into four factors ; Emotional/aesthetical value, Epistemic value, Functional value and Social value. The clothing shopping orientation as consumer variable extracted six factors ; Recreational orientation, Economical orientation, Brand/store loyalty orientation, Careful orientation, Apathetic orientation and Positive orientation. Consumers were classified by the cloting shopping orientation into the Convenience shopper, the Recreational shopper, the Economical shopper and the Careful shopper. Second, In comparison with the unimpulse-buyin groups, the impulse-buying group is more effected by in-store situation than purchase situation, and were more effected by Emotional/aesthetical value, Social value and Epistemic value of the consumption value. In consumer types, the more was the Recreational shopper and the Convenience shopper, the more showed impulse buying behavior. And the important factor distinguished between the impulse buying group and the unimpulse buying group was the Salesman/store atmosphere of the in-store situation.

Questionnaires were distributed to 300 women who lived in the Seoul area and between 40 to 65 years of age. A sample of 248 women responded. To analyze the data, Factor Analysis, Cluster Analysis, Analysis of Variance (ANOVA) and a Duncan test were used. As a result, the respondents were clustered into 4 different groups according to lifestyles. The groups included practical oriented group, economic oriented and practical group, active oriented and appearance group, and economic group. Their buying behavior was as follows. First, the active oriented and appearance group shopped at department stores and specialty stores; however, the economic oriented and practical group shopped at discount stores more often than other groups. The practical group shopped more frequently using TV home shopping networks, discount stores, and outlet stores, the economic group shopped at off-price stores, discount stores, and online more than the other groups. Second, the active oriented and appearance group bought classic suits and semi-classic suits, imported brand and/or designer brand apparel more often than other groups. Third, the active oriented and appearance group perceived another person's appearance, advertisement, and shop display as a more important information source than other groups. Forth, the active oriented and appearance group considered design & style, harmony with self-image, brand name, color, and coordination with other clothing as more important selection factors for clothing than other groups. The economic groups considered coordination with other clothing; however, the economic oriented and practical group cited ease of care as more important factors.

The purpose of this study is to investigate the determinants of intent to leave among workers at long-term care institutions in South Korea. The model represents a revision of the Price(2001) model which extends previous research by providing a comprehensive review of the economic, psychological, sociological literature. This study also examined the moderating effects of values toward independent variables on the job satisfaction and organizational commitment. The sample used in this study consisted of 400 workers from 9 long-term care hospitals and facilities nationwide. Data were collected with self-administered questionnaires and analysed using multiple regression analysis and path analysis. The main results of the study were as follows. The variance of job satisfaction and organizational commitment explained by the independent variables used in the study are 74.5% and 76.3% respectively. The results of this study revealed that the following variables have significant negative effects on intent to leave among workers; organizational commitment, job satisfaction, positive affectivity, supervisor support, job significance, job security, job growth. And the following variables have significant positive effects on intent to leave among workers; job opportunity, negative affectivity. This result is same when the moderating role of values were considered in the analysis.

We analysised the effect of harmonics on electric machines of substation power system barred on quantitatively measured harmonics and proposed the methods for prevention of harmonics through checking on transformer, rectifier and cable's capacities against harmonics with reference to KEPCO's electricity service standard. In order to analysis harmoninics of silicon rectifier that is power source in DC substation, computer simulations for a substation with TR of high voltage distribution switchboard are performed. Simulation results show that the total harmonic distortion factor becomes smaller for TR primary and receiving points in order rather than silicon rectifier which is harmonic generation source so that the harmonics generated frets each rectifier are outflowed to power supply and high voltage distribution switchboard The result of higher distortion factors of voltage and current for rectifier with 100% load than those with 50 % and 30% indicates that the waveform of voltage and current for the real substation power system at the office-going and the closing hours with heavy loads might be more distorted. As proposed methods for harmonic reduction, the conventional 6 pulse-type for substation is required to be replaced by 12 pulse-type for reduction of 5th and 7th harmonics. The active filter rather than the passive filter is more effective due to severe variance of rectifier loads, but the high cost is price to be paid. In view of installation area and costs, the use of 12 pulse-type transformer is desirable and then the parallel transformer and the rectifier within the substation must be replaced at the same time. Other substations with parallel feeder can use 6 pulse-type transformer.

Four carcass traits, namely carcass weight (CW), eye muscle area (EMA), back fat thickness (BF), and marbling score (MS), are the main price decision parameters used for purchasing Hanwoo beef. The development of DNA markers for these carcass traits for use in a beef management system could result in substantial profit for beef producers in Korea. The objective of this study was to validate the association of highly significant single nucleotide polymorphisms (SNPs) identified in a previous genome-wide association study (GWAS) with the four carcass traits in a commercial Hanwoo population. We genotyped 83 SNPs distributed across all 29 autosomes in 867 steers from a Korean Hanwoo feedlot. Six SNPs, namely ARS-BFGL-NGS-22774 (Chr4, Pos:4889229), ARS-BFGL-NGS-100046 (Chr6, Pos:61917424), ARS-BFGL-NGS-39006 (Chr27, Pos:38059196), ARS-BFGL-NGS-18790 (Chr10, Pos:26489109), ARS-BFGL-NGS-43879 (Chr9, Pos:39964297), and BTB-00775794 (Chr20, Pos:20476265), were found to be associated with CW, EMA, BF, and MS. The ARS-BFGL-NGS-22774, BTB-00775794, and ARS-BFGL-NGS-39006 markers accounted for 1.80%, 1.72%, and 1.35% (p<0.01), respectively, of the phenotypic variance in the commercial Hanwoo population. Many genes located in close proximity to the significant SNPs identified in this study were previously reported to have roles in carcass traits. The results of this study could be useful for marker-assisted selection programs.
