As multicultural family gradually increased, our society is changing towards multicultural society. This study tried to identify the factors related with social distance of adolescent of multicultural family. The participants were 568 middle school students living in S city, D and H county in Chungnam province. Data for the study were analyzed by frequency, mean comparison, correlation and regression analysis. The study results were summarized as follows. First, there were significant differences in social distance according to gender, school record, and place of residence. Second, there were significant differences in social distance according to degree of intimacy between general adolescents. Third, as a result of correlation analysis, the lower self-esteem was, the lower value orientation was, the lower cultural diversity was; the higher social distance is. Accordingly, social distance for adolescents had negative correlations with self-esteem, value orientation, and cultural diversity. Fourth, variables affecting social distance were gender, school record, family composition, place of residence, friend from multicultural family, intention to be a friend, experience of overseas travel, self-esteem, value orientation, cultural diversity. Among them, intention to be a friend was a main predictor.

The purposes of this study were to examine the conceptual structure of shopping value, evaluative criteria of golf wear and store choice behavior, and to investigate the effect of shopping value and evaluative criteria of golf wear on store choice behavior. Data were obtained from 415 men and women aged 20-60 who had purchased golf wears living in Busan. The results of the study were as follows: Shopping value were composed of Hedonic shopping value and Utilitarian shopping value, and evaluative criteria of golf wear were consisted of Size/design.quality, Fitness/appropriateness of use, and Fashionability/brand. Stores choice behavior were composed of Atmosphere/salesperson, Diversity of product/service, Display/assortment, and convenience of location. Hedonic consumers tended to consider the price and display/assortment when they chose golf wear stores, and they were more likely to consider display/assortment mediated by fashionability/brand. But utilitarian consumers perceived less important diversity of product/service when they chose golf wear stores. Consumers who chose golf wear depending on fittness/design and quality patronaged stores offering diverse product/service.

Social commerce is not only a new form of shopping malls that did not exist in the past, but also a new form of media as it gets combined with social networking services. The purpose of this study is to analyze the influence of clothing involvement on the relationship between shopping values, attitudes, and purchase intentions of consumers in the group-buying type of social commerce. A specialized Internet survey company carried out the survey targeting consumers in their 20s and 30s with experience of purchasing fashion products using group-buying type of social commerce. A total of 200 questionnaires were used for the final analysis. Descriptive statistics, factor analysis, t-test, and regression analysis were conducted by using SPSS 12.0 and AMOS 19.0. The results are as follows. First, diversity/informativeness, impulse/accumulation, price, convenience, reliability, interaction, and adventure were identified as shopping value dimensions. Second, especially in cases of diversity/informativeness, price, and interaction, there were significant differences between the high involvement group and the low involvement group. Third, five of the categories, which were diversity/informativeness, price, convenience, reliability, and interaction, had significant influence on attitude and purchase intention. When the attitude variable was included with shopping value as independent variables in the regression model to predict purchase intention, the attitude variable presented a full mediating effect or a partial mediating effect between shopping value and purchase intention. Also, the relationship among shopping value, attitude, and purchase intention was different to some degree according to the level of consumer clothing involvement.

Background: To effectively understand and evaluate plant diversity in a specific area and make meaningful comparisons between regions, standardized methods that measure diversity irrespective of survey plot size are crucial. This study proposes a model equation for comparing plant species diversity using the modified Whittaker plots. Plant species diversity was measured in two Gotjawal areas on Jeju Island, where the coexistence of northern and southern limit species significantly impacts diversity. By analyzing the relationship between plant species diversity and environmental factors, the study clarified the characteristics of plant and habitat diversity in the Gotjawal ecosystem. Results: The species richness of vascular plants, herbaceous plants, and woody plants increased with area and was higher in Jeoji Gotjawal than in Seonheul Gotjawal. Similarly, the species turnover rate (slope value) was higher in Jeoji Gotjawal (4.37) than in Seonheul Gotjawal (3.85). This indicates that the species richness in Jeoji Gotjawal increases more with the expansion of the survey area (1-1,000 m²), reflecting a faster species turnover rate. Additionally, in Gotjawal areas, species richness increased with greater leaf litter depth, elevation, slope, and rock ratio. These results indicate that differences in plant species diversity were attributed to soil environmental factors. Conclusions: The plant species diversity of Gotjawal, surveyed using standardized methods, was lower than that of forested areas in the central region of South Korea where the same method was applied. Most previous studies on species diversity likely compared diversity without considering a consistent survey area. Therefore, when comparing plant species diversity domestically and globally, it emphasizes the need for the use of standardized survey methods.

In this paper, selection criterions on selection diversity are researched. The diversity is applied to the multiple antenna system based on wireless access in vehicular environment (WAVE) standard for rapid varying channel. Least squares (LS) based decision feedback equalizer (DFE) are used for channel equalization. Received signal is regenerated by means of the decision feedback path. In the selection diversity, the regenerated signal as well as the received signal is selected according to selection criterion. The decision feedback algorithm can follow the fast speed of WAVE fading channel. To control the tracking speed of the time-varying channel, simple low pass filter is used. Finally, the estimated channel value recovers the distorted payloads. Signal power before automatic gain control (AGC) in analog stage can be used as a selection criterion. In the digital stage, signal power after AGC, noise power after AGC, signal to noise ratio after AGC and cross-correlation method can be used as selection criterions. According to the simulation results, the performance of the selection diversity is improved in comparison with that of the combining diversity for the WAVE fading channel.

Agastache rugosa, a member of the mint family (Labiatae), is a perennial herb widely distributed in East Asian countries. It is used in traditional medicine for the treatment of cholera, vomiting, and miasma. This study assessed the genetic diversity and population structures on 65 accessions of Korean mint A. rugosa germplasm based on inter simple sequence repeat (ISSR) markers. The selected nine ISSR primers produced reproducible polymorphic banding patterns. In total, 126 bands were scored; 119 (94.4%) were polymorphic. The number of bands generated per primer varied from 7 to 18. A minimum of seven bands was generated by primer 874, while a maximum of 18 bands was generated by the primer 844. Six primers (815, 826, 835, 844, 868, and 874) generated 100% polymorphic bands. This was supported by other parameters such as total gene diversity ($H_T$) values, which ranged from 0.112 to 0.330 with a mean of 0.218. The effective number of alleles ($N_E$) ranged from 1.174 to 1.486 with a mean value of 1.351. Nei's genetic diversity (H) mean value was 0.218, and Shannon's information index (I) mean value was 0.343. The high values for total gene diversity, effective number of alleles, Nei's genetic diversity, and Shannon's information index indicated substantial variations within the population. Cluster analysis showed characteristic grouping, which is not in accordance with their geographical affiliation. The implications of the results of this study in developing a strategy for the conservation and breeding of A. rugosa and other medicinal plant germplasm are discussed.

Plasmodium vivax variant interspersed repeats (vir) refer to the key protein used for escaping the host immune system. Knowledge in the genetic variation of vir genes can be used for the development of vaccines or diagnostic methods. Therefore, we evaluated the genetic diversity of the vir genes of P. vivax populations of several Asian countries, including Pakistan, which is a malaria-endemic country experiencing a significant rise in malaria cases in recent years. We analyzed the genetic diversity and population structure of 4 vir genes (vir 4, vir 12, vir 21, and vir 27) in the Pakistan P. vivax population and compared these features to those of the corresponding vir genes in other Asian countries. In Pakistan, vir 4 (S=198, H=9, Hd=0.889, Tajima's D value=1.12321) was the most genetically heterogenous, while the features of vir 21 (S=8, H=7, Hd=0.664, Tajima's D value =-0.63763) and vir 27 (S =25, H =11, Hd =0.682, Tajima's D value=-2.10836) were relatively conserved. Additionally, vir 4 was the most genetically diverse among Asian P. vivax populations, although within population diversity was low. Meanwhile, vir 21 and vir 27 among all Asian populations were closely related genetically. Our findings on the genetic diversity of vir genes and its relationships between populations in diverse geographical locations contribute toward a better understanding of the genetic characteristics of vir. The high level of genetic diversity of vir 4 suggests that this gene can be a useful genetic marker for understanding the P. vivax population structure. Longitudinal genetic diversity studies of vir genes in P. vivax isolates obtained from more diverse geographical areas are needed to better understand the function of vir genes and their use for the development of malaria control measures, such as vaccines.

Purpose - The principle aim of this study is to further investigate the relationship between market diversity and export performance. We examine the benefits and costs of geographic market diversity regarding the number of countries exported to by firms on their export performance. Based on the financial risk reduction model and the entry costs model, we propose a way to incorporate the costs and benefits aspects of market diversity. Design/methodology - To empirically investigate our research question, the curvilinear relationship between market diversity and export performance, we built a secondary panel data set between 2015 and 2019, containing 17,863 observations of Korean exporting companies. A generalized least squares panel estimator with fixed effects was employed to test the hypothesis, and the statistical package, Stata 14, was used. Findings - Our main findings are as follows: As market diversity increases, export performance increases because exporters can diversify and reduce financial risks in export markets. However, the relationship between the two does not grow. As it peaks, the entry costs increase due to the high market diversity, thereby outweighing the benefits, leading, eventually to decrease in the export performance. Consequently, there is an inverted U-shaped relationship between market diversity and export performance. Originality/value - In the export and trade literature, the impact of market diversity on export performance has not been addressed yet, despite the importance of this subject. Many scholars have assumed a positive linear relationship between the two, considering only the decrease in market risks as the number of overseas markets increases, without examining the increase in the entry and management costs. Therefore, our study contributes by providing a new perspective for analyzing the characteristics and outcomes of market diversity.
