  • The numerical taxonomy of heterotrophic bacterial community in Lake Soyang was analysed. 95, 115, 88 and 75 strains which were isolated at each season from spring in 1987 to winter in 1988 were clustered by single matching coefficient. The diversity indices (H') were in the range of 0.511-1.684, and the community was most diverse in spring. THe seasonal variation of generic composition was significant. Of the domonant genera, Acinetobacter, Pseudomonas, and Flavobacterium were representative.

  • The species diversity of Orchidaceae is believed to be extremely high in Myanmar. Like in other plant groups, little basic inventory work has been done thus far. During floristic surveys conducted in Popa Mountain Park (Mandalay Region), Natma Taung National Park (Chin State), and in the Ywangan area (southwestern Shan State), we encountered two interesting orchid species which were determined to be new generic records in the flora of Myanmar. Thuniopsis cleistogama was previously considered endemic to Yunnan Province (China) and was only known from the type locality. However, here the species is newly reported from two localities in central and western Myanmar. Disperis neilgherrensis is known from several widely scattered localities in tropical and subtropical Asia. This tiny orchid species was discovered in the Ywangan area in the southwestern area of the Shan State of Myanmar. These two species will be valuable additions to the updated checklist of the orchids of Myanmar.

  • The research empirically analyzes the impact of technological regime of game engine upon game development performance. The results indicate that, first, technological regime of game engine determines game's genre distribution. Secondly, user friendly game engine regime(modular, generic and integrated API engine) induces higher genre diversity and lower genre concentration ratios. Thirdly, user friendly game engine regime(modular, generic and integrated API engine) is becoming more applied recently. Fourthly, innovation types and price types of game engine do not influence upon game engine trades. Those results point out that game engine's technological regime influences directly game development application and user friendly regime is increasingly more standardized.

  • Tripterygium wilfordii Hook.f. (Celastraceae), collected from Phia Oac-Phia Den National Park of Vietnam, is reported here as a new generic and species record for the flora of Vietnam. The genus Tripterygium differs from other genera of Celastraceae by its samara fruits, which become three-winged at maturity, and a scandent shrub. Taxonomic notes, descriptions, line drawing and photographs are provided, together with short notes on the distribution, ecology and phenology of Tripterygium wilfordii Hook.f. (Celastraceae).

  • Ergasilus zacconis (Yamaguti, 1936), the copepod parasite originally named as Pseudergasilus zaconnis, is redescribed based on the specimens newly collected from the freshwater fish Zacco platypus (Temminck and Schlegel) from Japan. Some errors appearing in the original description are emended. An explanation for the generic position of this species is given.

  • Different actinomycete strains were isolated from natural lime caves of Ondal Chemongok Hwanseon and Yongyeon which are located at Kangwon or chungcheongbook province in Korea and were identified to the genus level. Soil sam-ples were collected at 6 sites inside and 2 sites outside of each natural lime cave, As the result the strains belonging to genus Streptomyces and rare actinomycetes were isolated at the average of 2.1 and 3.4 strains per g soil on inside cave whereas which were isolated at the 6.0 and 1.8 strains per g soil on outside cave. How-ever the generic distribution of Streptomyces and rare actinomycetes isolated from outside cave was quite dif-ferent from that of inside cave. It was shown that rare actinomycetes at natural lime caves is generally highly abundant than Streptomyces.

  • The application of modern ecological, ultrastructural and molecular methods, aided by the cultivation of numerous cyanobacterial morphotypes, has substantially changed our knowledge of these organisms. It has led to major advances in cyanobacterial taxonomy and criteria for their phylogenetic classification. Molecular data provide basic criteria for cyanobacterial taxonomy; however, a correct phylogenetic system cannot be constructed without combining genetic data with knowledge from the previous 150 years research of cyanobacterial diversity. Thus, studies of morphological variation in nature, and modern morphological, ultrastructural, ecophysiological and biochemical characters need to be combined in a “polyphasic” approach. Taxonomic concepts for generic and infrageneric ranks are re-evaluated in light of combined phenotypic and molecular criteria. Despite their usefulness in experimental studies, the limitations of using strains from culture collections for systematic and nomenclatural purposes is highlighted. The need for a continual revision of strain identification and proper nomenclatural practice associated with either the bacteriological or botanical codes is emphasized. Recent advances in taxonomy are highlighted in the context of prospects for understanding cyanobacterial diversity from natural habitats, and the evolutionary and adaptational processes that cyanobacteria undergo.

  • As the millennials continue to mature and enter the workforce, it is important that employers understand what this generation expects from all aspects of their employment and leadership preferences in order to prepare them to be the next millennials leaders. The purpose of this research is to determine the generic attributes of the new millennial leaders in Malaysia. The survey is distributed among executives in the selected government-linked, multinational, and public-sector companies in Malaysia, with 237 (72%) of whom being millennials. Partial least square (PLS-SEM) via software SmartPLS 3.0 was applied to evaluate the measurement model and the structural model. Results from this study indicate that the attributes of the millennials leader are innovative (0.213), inspiration (0.128), and visionary (0.122). Thus, organization can focus on those attributes in preparing the millennials for being the next generation of leaders. This study offers important implications to researchers as well as practitioners, and highlights the leadership attributes that could help in enhancing millennials leadership. This study produces a new millennials leadership attributes model for millennials leaders in Malaysian companies; with millennials becoming the fastest-growing age groups in the organizations, this study will promote effective and efficient skills for the millennials.

  • Purpose - This study aims to understand the brand marketing of agricultural products and redefine their status in South Korea by analyzing impacts on consumer buying behaviors. Research design, data, and methodology - Products, with independent variables, were divided into agricultural brand products and generic products. Dependent variables were limited to expanding sales of a specialty brand through consumer awareness, consumer buying behavior, and confidence in agricultural products' quality. Control variables were based on characteristics of products such as freshness, safety, quality, and their category. Moderating effects were examined on consumer characteristics, including income levels and age. Results - Consumers increasingly purchased agricultural brand products rather than generic agricultural products because of the general reliability of quality assurance. Conclusions - Large agricultural specialty stores have enhanced the perceptions of quality assurance, freshness, safety, and diversity. Through a critical analysis of the domestic consumer income levels and age, gender, and demographic factors, such as agricultural consumer buying behavior not affecting consumers' health and life, this study proposes positive changes in quality perception.
