This study investigate the effects of environmental and organizational characteristics on e-business competence and the influence of e-business competence on export performance in the small and medium sized firms. The development of the research model is based on the literature of e-business and the empirical studies of information technology competence. The data from the survey was analyzed using Partial Least Squares(PLS). The results from the empirical model suggest that e-business competence is affected by environmental uncertainty and market diversity as well as top management support and learning orientation. And, export performance is enhanced by e-business competence.

This study is about online purchases of foods that have been reluctant to deal with distribution processes and reliability issues. We find out that attributes of the online food market affects behavior intention and whether it differs according to consumption tendency. A survey was conducted on consumers who had ever purchased food online for hypothesis testing. Reliability and feasibility were reviewed for the collected data and the hypothesis was verified through structural equation model analysis. While product diversity, product information and customer service factors of the online food market significantly affect behavior intention, price is not. We identified differences in the impact of behavior intention on consumption tendencies. For the Gaseongbi group, only the product information factors have significant effect on behavior, and for the Gasimbi group, the price and customer service factors have a significant effect on behavior intention. The findings provide theoretical and practical implications for marketers to study various marketing method based on consumer tendencies.

A spotted scat, Scatophagus argus, has a high nutritional value and is among Asia's most widely consumed fish species. Thua Thien Hue's consumption market considers this species to be of high economic value and requires protection and conservation of the population. However, the studies on the identification and genetic diversity of S. argus distributed in Vietnam are still lacking. Therefore, mitochondrial cytochrome c oxidase subunit I (COI) gene was utilized to distinguish different populations and investigate the genetic diversity of two populations of S. argus from Tam Giang lagoon, Thua Thien Hue province (n = 31) and Ca Mau province (n = 14). The sequencing results indicated 13 distinct haplotypes among 45 sequences. Five single nucleotide polymorphisms were observed to distinguish Hue spotted scat population. The S. argus population in Ca Mau province was higher haplotype diversity (Hd) and nucleotide diversity (π) than those of Thua Thien Hue province, which demonstrates that there are minor differences between haplotypes. There were genetic distances ranging from 0%-4% within the populations and 6.67% between the two populations. In addition to the sequencing, the comparison of morphology, biology, culture, and the growth rate was sufficient to distinguish the spotted scat S. argus in Thua Thien Hue from Ca Mau.

Background: The live bird market (LBM) plays an important role in the dynamic evolution of the avian influenza H5N1 virus. Objectives: The main objective of this study was to monitor the genetic diversity of the H5N1 viruses in LBMs in Indonesia. Methods: Therefore, the disease surveillance was conducted in the area of Banten, West Java, Central Java, East Java, and Jakarta Province, Indonesia from 2014 to 2019. Subsequently, the genetic characterization of the H5N1 viruses was performed by sequencing all 8 segments of the viral genome. Results: As a result, the H5N1 viruses were detected in most of LBMs in both bird' cloacal and environmental samples, in which about 35% of all samples were positive for influenza A and, subsequently, about 52% of these samples were positive for H5 subtyping. Based on the genetic analyses of 14 viruses isolated from LBMs, genetic diversities of the H5N1 viruses were identified including clades 2.1.3 and 2.3.2 as typical predominant groups as well as reassortant viruses between these 2 clades. Conclusions: As a consequence, zoonotic transmission to humans in the market could be occurred from the exposure of infected birds and/or contaminated environments. Moreover, new virus variants could emerge from the LBM environment. Therefore, improving pandemic preparedness raised great concerns related to the zoonotic aspect of new influenza variants because of its high adaptivity and efficiency for human infection.

이 논문에서는 새로운 뉴스에 대해 선물시장이 현물시장보다 더 민감하게 반응하는지와 더 큰 가격변동폭을 보이는지를 검증한다. 뉴스에 대한 민감도는, 선물가격의 일간변동을 이론가격 변동에 관해 회귀시킨 식의 회귀계수에 의해 측정한다. 그리고 가격변동폭은 선물가격과 이론가격의 평균범위차이($\overline{RD}$), 평균고가차이($\overline{HD}$) 및 평균저가차이($\overline{LD}$)라는 세 가지 척도를 사용하여 측정한다. 이 논문에서 사용한 자료는 코스피200 지수선물시장의 개설 초기인 1996년 7월부터 최근의 2005년 12월말까지 최근월물과 차근원물의 선물가격과 이론가격이다. 민감도의 차이를 나타내는 $\hat{\beta}$는 1과 크게 유의한 차이를 보이지 않으므로 뉴스에 대한 두 시장의 민감도는 대체로 큰 차이가 있는 것으로 보이지 않는다. 그러나 최근기간(2002년 11월${\sim}$2005년 12월)에는 최근월물 및 차근월물 모두 1보다 큰 값을 보이고 있어 선물시장이 더 민감하게 반응하고 있다. 또 최근기간에 최근월물의 가격이 좋은 뉴스에 대해 현물시장보다 더 민감하게 반응하였다. 전체기간 및 하위기간의 ($\overline{RD}$)는 대체로 0과 유의한 차이를 갖지 않는다. 그러나 최근월물의 평균고가차이($\overline{HD}$)는 전체기간과 하위기간 모두에서 뚜렷하게 유의한 양의 값을 보이고 있다. 이것은 최근월물 선물가격의 좋은 뉴스에 대한 가격변동폭이 현물가격보다 더 크다는 것을 의미한다.

본 연구는 시청자가 접하는 기본적인 방송서비스로서 케이블 상품의 다양성을 연구하였다. 다양성은 방송정책의 가장 기본적인 목표로 중요한 함의를 가지고 있다. 하지만 아직까지 케이블과 같은 유료매체의 시청다양성에 대한 연구는 제한적으로 이루어져왔다. 이에 케이블 SO가 제공하는 상품별로 시청자가 제공받는 채널의 수와 공급분야의 다양성을 비교 검증하였다. 분석결과 케이블 상품의 가격별이 상승할수록, 제공되는 채널의 수와 채널이 공급하는 분야의 다양성이 증가하였다. 이는 SO의 시장 전략에 따른 당연한 결과이지만, 상품별로 다양한 채널이 제공되어야 하는 정책적 관점에서는 가격에 따라 시청자의 선택의 다양성이 상당히 제약 받을 수 있다는 것을 의미한다. 즉 시청자가 다양한 분야의 채널을 시청할 권리가 제한되고 있었다. 이러한 현상을 개선하기 위해 유료 방송서비스의 상품별 채널 다양성 지수를 관리할 필요성을 제기하였다.

This study examines the relationship between board gender diversity and financial performance. The annual data of Palestinian nonfinancial listed enterprises from 2015 to 2019 was analyzed using a longitudinal panel analysis for the study's purposes. When conditional mean regression methodologies were used in the study, the results indicate that there is an insignificant relation between board gender diversity and firm financial performance. However, when analyzing women directors' effect on a firm's financial performance, endogeneity is always a concern, therefore, we test for endogeneity by employing the Darbin-Wu Housman test and then by using 2SLS. Nevertheless, when looking at the dispersion of a firm's performance using quantile regression, the results show that having women on the board improves financial performance slightly, especially for high-financial-performing firms. The findings indicate that there is a legal significant gap hindering the protection of gender diversity in boardrooms, and limiting the existence and representation of women in leadership positions, specifically, board of directors. The results of this study contribute to corporate governance and business culture literature by shedding the light on the importance of board gender diversity, to improve the firm financial performance, and hence, protect the interests of all shareholders' categories.

This paper presents two social and academic studies on the boundary between cultural production and consumption. The first line of the study on cultural omnivore analyzes the choice of heterogeneous audiences in the face of various cultural offerings. The second line is a study of market categories, which analyzes the responses of peer audiences to objects with different levels of category code compliance. As such, this paper developed a heterogeneous audience model to evaluate objects of different types. This allows us to consider two dimensions of cultural preference: diversity and orientation of selection. To this end, this paper proposes a new analytical frame work to map consumption behavior on these two dimensions. The results suggest that one type of target that values diversity and transformation is particularly resistant to those that span boundaries. We test this argument in the analysis of two large data sets on film and restaurant reviews. Overall, our findings can extend beyond cultural consumption. Outline variability of contextual individuals or individuals in the same situation can cross cultural boundaries even if they are not intentionally pursuing such hybridism.
