This study developed a structural model to examine the relationships among consumer traits, self-brand connections, and purchase intentions for local fashion brands under "Guochao" consumption in China. An online survey with a self-administered questionnaire was undertaken through Chinese SNS tools to collect the data. A total of 276 usable responses were obtained from Chinese consumers who are residents in China. More females(n=174, +63%) than males (n=102, 37%) participated, and they were aged from 18 to 45 years old. The measurement model was confirmed to be reliable and valid. In the estimated structural model, the consumer traits of ethnocentrism and cultural affinity positively affected the self-brand connection, leading to purchase intentions for the local fashion brands. Specifically, the ethnocentrism factor indirectly affected the purchase intentions by mediating the self-brand connection, while the cultural affinity factor had significant direct effects on purchase intentions. Thus, a partial mediating effect of self-brand connection was found in the relationship between the consumer traits(ethnocentrism and cultural affinity) and purchase intentions of local fashion brands in the cultural "Guochao" consumption context. This study provides insights into extending the cultural theory of ethnocentrism relevant to self-brand connections and discusses the managerial implications for developing strategic global branding in the Chinese fashion markets.

The fractal study in river basin has been performed for the sinuosity of an individual stream and bifurcation of the stream network. The previous studies has suggested many methods or equations for the fractal dimension estimation in a river network. This study used those many equations for the estimation of fractal dimensions on the streams such as Bokha, Gonjiam, and Pocheon streams. The estimated dimensions are in the range of 1 to 1.359 for the individual stream and 1.634 to 2 for the stream network. The most of equations were suggested based on the assumption of self-similarity of a river basin for the individual stream and stream network. However, the real river basin could be characterized by self-affinity rather than self-similarity. Even though we estimate the dimensions by using many equations, we could not recommend which one is better equation for the estimation of fractal dimension. This might be from the self-similarity assumption of equations. Therefore, the assumption and research work of self-affinity will be needed for the appropriate estimation of fractal dimension in river basin.

Production of high affinity antibodies for antigens is a critical component for the immune system to fight off infectious pathogens. However, it could be detrimental to our body when the antigens that B cells recognize are of self-origin. Follicular helper T, or Tfh, cells are required for the generation of germinal center reactions, where high affinity antibody-producing B cells and memory B cells predominantly develop. As such, Tfh cells are considered as targets to prevent B cells from producing high affinity antibodies against self-antigens, when high affinity autoantibodies are responsible for immunopathologies in autoimmune disorders. This review article provides an overview of current understanding of Tfh cells and discusses it in the context of animal models of autoimmune diseases and allograft rejections for generation of novel therapeutic interventions.

본 연구에서는 집수평면의 신장도에 대한 검토와 함께 자연유역의 자기유사성 및 자기상사성을 고려하여 Hack의 법칙에 대한 체계적인 접근을 수행하여 보았다. DEM으로부터 추출된 대상유역의 집수평면들은 Hack의 법칙에 대한 두 가설이 상호작용을 할 경우 나타날 수 있는 유역 형상들에 대한 모집단처럼 나타났다. 유역면적에 따른 집수평면 신장도의 변화를 도시해 본 결과 유로연장을 기반으로 한 고전적인 지형인자들보다는 관성적률을 기반으로 한 신장도가 보다 직관적인 결과를 줄 수 있을 것으로 판단되었다. Hack의 법칙에 대한 지수 h는 Gray (1951)의 연구결과와 유사하게 산정됨을 확인할 수 있었다. 하지만 대상유역들에 대한 Hurst의 지수 H는 0.96으로 나타나 본 연구에서 고려한 집수평면들은 규모에 따라 등방성 성장률을 가지고 있는 것으로 사료되었다. 이로부터 본 연구의 대상유역들의 형상은 집수평면의 자기유사성보다는 유로연장의 자기상사성에 더 영향을 받는 것으로 추론할 수 있었다.

The demand of rural tourism industry has increased among the urbanites in South Korea, in due to the increase of leisure activity and the emergence of ageing society. Rural amenity resources are gaining various interests, in the value creation and promotion of tourism. In this study, the propensities of city dwellers were separated by life-style classification, and each affinity to the rural amenity resources was examined in accordance with the separation. A questionnaire survey of urbanites in the southern area of Gyeonggi-do, the most populous province in South Korea, was conducted to analyze the preference of city dwellers about rural amenity resource and life-style of themselves. For statistical verification, $IBM^{(R)}$ $SPSS^{(R)}$ Statistics 20 software was used for frequency, reliability, factor and multiple regression analysis of this research. The results of the statistical analyses found a noticeable characteristic in life-style classification. The affinities of urbanites can be classified into four congregations of life-style factors in this statistical model. Each congregation of the factors was named as 'Self-development-oriented', 'Leisure-oriented', 'Achievement-oriented', and 'Culture-oriented' life-style, to represent the characteristics for convenience' sake. Among these styles, only 'Self-development-oriented' and 'Achievement-oriented' showed the positive correlation with rural amenity resources in the multiple regression analysis. In addition, the rural amenity resources were also analyzed in accordance with the life-styles classification of urbanites. City dwellers showed the highest interest to the 'natural resource management facility resource' in natural resources, the 'traditional heritage resource' in cultural resources, and the 'community resource' in social resources. Meanwhile, they showed less interest to 'agricultural and scenery resources' in natural resources, 'specialty production resource' in cultural resources, and 'cooperative farming' in social resources. These characteristics can be constructed as meaning that the urbanites who concern self-development and achievement of their lives have high interest in rural amenity resources, and the main interest of them is not 'return-to-the-farm'(歸農) but 'return-to-the-home'(歸村).

This study aims to investigate the effect of personality traits (Big5) of local government officials on job exhaustion. First, we examine the correlation between personal characteristics of individual employees and self-efficacy and the correlation between factors of civil servants' personality characteristics and job stress. Also, it was confirmed whether self-efficacy had a significant effect on job exhaustion and whether job stress had a significant effect on job exhaustion. In order to empirically study this research model, we held a survey based on the employees of Gangnam-gu, Seoul. The main results of this study are as follows : First, it was confirmed that sincerity among personality characteristics affects positive self-efficacy and neuroticism affects negative self-efficacy. However, it was confirmed that extroversion, affinity, and openness were not correlated with self-efficacy. Second, neuroticism has a positive influence on job stress and openness has a negative effect on job stress. However, there was no correlation between extroversion, affinity, sincerity and job stress. Third, the relationship between self-efficacy and job exhaustion turned out to give a negative effect. Finally, job stress was positively influenced by job exhaustion. Therefore, it is necessary to apply the study on personality characteristics (Big5), job stress, and job exhaustion, which have been studied based on service industries, to local government officials. The purpose of this study is to suggest job training for enhancing personality traits that can help reduce the job burden of local government officials.

The methyl-directed mismatch repair (MMR) mechanism has been extensively studied in vitro and in vivo, but one of the difficulties in determining the biological relationships between the MMR-related proteins is the tendency of MutL to self-aggregate. The properties of a stable MutL homologue were investigated using a thermostable MutL (TmL) from Thermotoga maritima MSB8 and whose size exclusion chromatographic and crosslinking analyses were compatible with a dimeric form of TmL. TmL underwent conformational changes in the presence of nucleotides and single-stranded DNA (ssDNA) with ATP binding not requiring ssDNA binding activity of TmL, while ADPnP-stimulated TmL showed a high ssDNA binding affinity. Finally, TmL interacted with the T. maritima MutS (TmS), increasing the affinity of TmS to mismatched DNA base pairs and suggesting that the role of TmL in the formation of a mismatched DNA-TmS complex may be a pivotal observation for the study of the initial MMR system.
