본 논문은 직교 주파수 분할 다중 반송파(OFDM, orthogonal frequency division multiplexing) 시스템의 다이버시티 효과를 향상시키는 순환 지연 다이버시티(CDD, cyclic delay diversity) 기법에서 최적의 순환 지연 값을 결정하는 방법을 제안한다. 순환 지연 다이버시티 기법에서는 순환 지연 값이 증가함에 따라 다이버시티 효과에 의한 SINR (signal to interference and noise ratio) 이득이 커지는 동시에 채널 추정 오류의 증가에 의한 SINR 손실도 커지는 상반 관계(trade-off)가 존재한다. 다이버시티 효과와 채널 추정 오류의 상반 관계가 존재할 때 제안된 방법을 통해 구한 최적의 순환 지연값을 순환 지연 다이버시티 기법에 적용하면, 목표로 하는 프레임 오류율(FER, frame error rate)을 만족시키기 위한 SINR을 최소화한다.

Disproportionating Enzyme 1 (DPE1) is an a-1,4-D-glucanotransferase that cleavages the a-1,4-glucosidic bonds and transfers glucosyl groups. In rice endosperm, it participates in starch synthesis by transferring maltooligosyl groups from amylose and amylopectin to amylopectin. Here, we investigated the haplotype variations and evolutionary indices (e.g., genetic diversity and population structure) for the DPE1 gene in 374 rice accessions representing seven subgroups (wild, indica, temperate japonica, tropical japonica, aus, aromatic, and admixture). Variant calling analysis of DPE1 coding regions leads to the identification of six functional haplotypes representing/occupying 8 nonsynonymous SNPs. Nucleotide diversity analysis revealed the highest pi-value in wild group (0.0556) compared to other cultivated groups, of which temperate japonica showed the most reduction of genetic diversity value (0.003). A significant positive Tajima's D value (1.6330) of admixture highlights sudden population contraction under balancing selection, while temperate japonica with the lowest Tajima's D value (-1.3523) showed a selection signature of DPE1 domestication which might be the cause of excess of rare alleles. Moreover, these two subpopulations exhibits a greater differentiation (F_ST=0.0148), indicating a higher genetic diversity. Our findings on functional DPE1 haplotypes will be useful in future breeding programs, and the evolutionary indices can also be applicable in functional studies of the DPE1 gene.

Objectives: The purpose of this study was to investigate the acceptance of family diversity among college students and related variables. Method: Data were collected by a structured questionnaire with 280 students who attended in three universities located in J province. SPSS Statistics Program version 24.0 was used to analyze the collected data. To answer the research questions, descriptive statistics, t-test, F-test, Pearson's correlation analyses, and regression analyses were performed. Results: The major results of the survey were summarized as below. First, the acceptance of family diversity among college students was slightly higher than the middle level(M=12.11). Most students accepted nuclear family as a typical family. More than half of the students accepted single parent families, adaptive families, step families, unmarried mother families, childless couples, homosexual families, elderly women living alone, and families composed of siblings as a family. Second, there was a significant difference by religiosity. Students without religion were higher than their counterparts with religion in a level of family diversity acceptance. Among the individual factors, third, a level of traditional family value had a significant negative effect on a level of family diversity acceptance. And perspective taking had a positive effect on a level of family diversity acceptance. Fourth, among the family factors, parent-child open communication did not affect a level of family diversity acceptance. However, parents' gender egalitarian beliefs had a significant positive effect on a level of family diversity acceptance. Lastly, regarding the relative effects of the personal and family factors, the traditional family value had the largest effect on a level of family diversity acceptance among college students. Conclusions: Base on these results, the implications and limitations of the study were discussed.

In this study, we suggest a new perspective on the linkage between alliance portfolio diversity and innovation performance based on a contingency approach. Using a longitudinal data set on alliance portfolios and patents of 182 firms in the U.S. manufacturing industries, we examined that alliance portfolio diversity has a U-shaped relationship with firm-level innovation. Internal value creation capabilities in terms of routine and ability are found to moderate the relationship between alliance portfolio diversity and innovation performance: Organizational search routine strengthens the relationship of alliance portfolio diversity and innovation performance while technological capabilities weaken and flip the relationship.

Based upon the vegetation data of woody plants by plot sampling method in the natural deciduous forest of Mt. Jeombong, the study was carried out to examine importance value, rank abundance curve, and species abundance curve, and comparatively evaluate seven different species diversity indices for Shannon-Wiener index, Simpson index, McIntosh index, Log series, Margalef index, Berger-Parker index, and species richness, according to topographic positions. The minimal area which meant only few more species were increased was 3.48 ha in total. The dominant species of valley were Carpinus cordata, Acer pseudo-sieboldianum, Quercus mongolica, Acer mono, and Abies holophylla, and the dominant species of mid-slope were Quercus mongolica, Acer pseudo-sieboldianum, Carpinus cordata, Tilia amurensis, and Fraxinus rhynchophylla. Moreover, the dominant species of ridge were Quercus mongolica, Acer pseudo-sieboldianum, Tilia amurensis, Fraxinus rhynchophylla, and Acer mono. According to rank abundance curve and species abundance curve, species evenness was also low. All of Log series, species richness, Margalef, and Shannon-Wiener index discriminated that valley had the highest diversity, and ridge had the lowest diversity; but, Simpson index, McIntosh index, and Berger-Parker index represented that mid-slope had the highest diversity, and ridge had the lowest diversity. Uniquely, in Berger-Parker index, mid-slope was the higher value than total.

Purpose - This study starts with the question of whether the capital market is likely to give positive valuations to companies that pursue diversity in their management and corporate governance structure. In this study, minority gender identity is considered as a diversity issue in management that has a socially negative perception. Design/methodology/approach - This study analyzed the relationship between corporate value in the capital market and the policies of companies that advocated minority gender identities, based on listed U.S. company data. Findings - This study finds that companies that support minority gender identities had a lower Tobin's q value than companies that did not. However, in the case of authenticity in terms of corporate governance diversity, the study finds that companies that advocate minority gender identities rather receive high firm valuation. In particular, companies with a high percentage of female directors show high corporate value even when implementing policies that support minority gender identities. Research implications or Originality - This study explores the capital market's response to diversity using past data in the U.S., but provides more practical implications for how companies should respond to a situation where an advocacy policy, based on more social recognition, for LGBT groups is established in Korea.

This study aimed at investigating the lexical diversity in the "Frog Story" narratives of Korean-Chinese bilingual children. Six bilingual speakers of Korean children- four boys and two girls- were audio recorded as they produced narratives based on pictures from the Mercer Mayer book "Frog, where are you?" The order of narration was counterbalanced. The vocabularies from narratives were analyzed by type, token, TTR (type-token Ratio) and D value using the CLAN (Computerized Language Analysis) program. The findings showed that the pattern of lexical diversity in Korean is similar with the Chinese, but the TTR and D value of Chinese still remain low in comparison with those of Korean. In addition, Korean language seems to have significant influence on Chinese in the language usage pattern and vice versa.
