Campylobacter jejuni is an important food-borne pathogen causing gastroenteritis in human. We isolated 208 strains of Campylobacter jejuni from 430 diarrhea patients and food employees with 17 food-poisoning outbreaks between 2014 and 2016 in Gyeonggi area. The strains were tested for genetic relationship and the genotype distribution using PFGE and multiplex-PCR typing. Among the 47 Penner-serotypes known for C. jejuni, it was identified as a genotype consisting of 35 genotypes by multiplex-PCR typing and represented 7 genotypes (HS2, HS4A, HS8, HS15, HS29, HS41, and HS53) in the selected strain. From the PFGE analysis of 11 food-poisoning outbreaks, 5 group of PFGE profile were obtained, and genetic similarity in these clusters ranged from 61.8 to 66.6%. This study examines the genetic diversity of C. jejuni that have been separated in the Gyeonggi area through various genetic analysis methods and identifies the correlation between strains in patients who have been infected with the disease in the future.

Hawaiian textile art has inspired artists and fashion designers worldwide and accounts for the high value of vintage Hawaiian apparel as collectibles. Other than tropical designs, a large portion of the textile art showcased the ethnic diversity of Hawai'i. In the 1800s, Hawai'i attracted immigrants from all over Asia, and the majority of Hawaii's residents today claim Asian ethnicity. This ethnic mix was made visible in textiles, a trend championed by Alfred Shaheen, an apparel manufacturer who loved Asian designs. He was committed to the celebration of cultural diversity at a time when Hawai'i was rapidly westernizing. The team of Asian textile artists he led created textile designs based on motifs and imagery from Asia. Shaheen's passionate vision led to the unique textiles produced in the 'golden age' of Hawaiian textiles, from 1940 through the 1960s. Alfred Shaheen has been called "Hawaii's Master Printer" and has been credited for turning Hawaiian textiles into art. The author's interviews with Mr. Shaheen were conducted over a decade, and form the basis for this paper in which Shaheen's own words are used to discuss his use of textile art in the transformation of the Hawaiian textiles and garment industry.

The gastrointestinal (GI) tract, including the rumen and the other intestinal segments of cattle, harbors a diverse, complex, and dynamic microbiome that drives feed digestion and fermentation in cattle, determining feed efficiency and output of pollutants. This microbiome also plays an important role in affecting host health. Research has been conducted for more than a century to understand the microbiome and its relationship to feed efficiency and host health. The traditional cultivation-based research elucidated some of the major metabolism, but studies using molecular biology techniques conducted from late 1980's to the late early 2000's greatly expanded our view of the diversity of the rumen and intestinal microbiome of cattle. Recently, metagenomics has been the primary technology to characterize the GI microbiome and its relationship with host nutrition and health. This review addresses the main methods/techniques in current use, the knowledge gained, and some of the challenges that remain. Most of the primers used in quantitative real-time polymerase chain reaction quantification and diversity analysis using metagenomics of ruminal bacteria, archaea, fungi, and protozoa were also compiled.

Purpose: The purpose of this study is to examine under what conditions suggestion programs conducted by organizations actually increase individual perception of their work effectiveness. Specifically, this study looks into the effects of cooperation perception and relational demography of employee on work effectiveness of suggestion programs. It does this by focusing on the interaction effect of organizational commitment. Research design, data and methodology: Data was collected from 1,872 participants who took part in the suggestion program of HCCP 6th DATA. This data was subjected to multiple regression analysis. Results: a) higher employee cooperation perception enhances work effectiveness of suggestion program, but relational difference of knowledge diversity between team members has no effect on work efficiency; b) Positive effect of cooperation perception, and difference in education level on work effectiveness become greater as commitment increases. However, organizational commitment decreases the positive effect of difference in organizational tenure on work effectiveness by suggestion program. Conclusion: The results point to the importance of broadening the current conceptual models of employee work effectiveness of suggestion program to include relational demography, as well as the utility of conducting additional cross-level research on suggestion programs.

The genus Scrophularia L. (Scrophulariaceae) comprises 200-270 species worldwide and is a taxonomically challenging lineage, displaying morphological diversity and hybridization. S. kakudensis is morphologically similar to the closely related taxa S. kakudensis var. microphylla, S. pilosa, and S. cephalantha. Therefore, the purpose of this study was to sequence the chloroplast (cp) genome of S. kakudensis using next-generation sequencing and compare it to those of related taxa. The complete cp genome sequence of Scrophularia kakudensis was found to be 152,355 bp long, consisting of a pair of inverted repeats of 25,485 bp that separate a large single-copy (LSC) of 83,479 bp from small single-copy regions of 17,909 bp. The cp genome contained 78 protein-coding genes, 30 tRNAs, and four rRNAs. A phylogenetic analysis based on 78 protein-coding genes from six Scrophularia species showed S. kakudensis and S. cephalantha formed with 100% bootstrap values. We compared the complete cp genomes of S. kakudensis and S. cephalantha and identified seven sequence divergence regions: matK/rps16, rps16/trnQ, trnS/trnG, rpoB/trnC, trnS/trnG, rpl32/trnL, and ndhD/psaC. These regions may be useful for determining the phylogenetic relationships among S. kakudensis-related species.

This study compared the stand structure of Abies koreana forests between Mt. Jirisan and Mt. Hallasan by analyzing DBH distribution, stem vitality, crown structure, importance value, species diversity, and DCA. The data were acquired through the national long-term ecological research project conducted by the Ministry of Environment. In the comparison of DBH class distribution, the stem density of A. koreana with DBH < 20 cm was higher in Mt. Hallasan than that in Mt. Jirisan; however, the stem density of A. koreana with DBH > 20 cm was higher in Mt. Jirisan than that in Mt. Hallasan. For A. koreana stem vitality, the ratio of alive standing was higher in Mt. Jirisan (72.0%) than in Mt. Hallasan (60.7%), whereas the ratio of alive leaning was higher in Mt. Hallasan (10.2%) than in Mt. Jirisan (1.1%). A. koreana stand in Mt. Jirisan was a mature stand with four evenly developed and distinct layers, whereas the tree layer in Mt. Hallasan was less than 10 m and the stand had three layers without a subtree layer. Mt. Hallasan's importance value of A. koreana was 39.4% higher than Mt. Jirisan's importance value of 26.6%. The species diversity of the A. koreana community of Mt. Jirisan was 2.52 times higher than that of Mt. Hallasan, which was 1.58. DCA results revealed that the average distance between Mt. Jirisan and Mt. Hallasan was relatively distinguished, and the degree of scattering of species composition of Mt. Jirisan was relatively dense compared with that of Mt. Hallasan.

The ancient fishing methods include stone fish weir, beach seine and baulk net, but the fish catches of the stone fish weir is the most abundant. The stone fish weirs not only constitute important landscape, but also are representative of the fishery culture in Penghu, because they are fishing ground built by ancient people to take advantage of natural environment and resources. The objectives of this study is to understand the relevance of stone fish weirs in Penghu and to preserve biological diversity, as well as the value of stone fish weirs in Penghu fishery culture, and further make suggestions on the stone fish weirs. According to the present study, the marine species around the stone fish weirs tend to be diversifying, and in the future the region's economy can be revitalized by sightseeing, which may promote the ecotourism, and also volunteer tourism. In the future, stone fish weirs must be promoted as a sightseeing destination. Also, by taking into consideration the experience of the Jibei stone weir protection team, the local communities of Penghu can have their own protection team to revitalize the stone fish weirs for sustainable operation and management.

The unique characteristics of the construction industry - such as the fragmentation of its processes, varied scope of works and diversity of its participants - are contributory factors to poor project performance. Several issues are unresolved due to the lack of a comprehensive technique to measure project outcomes including: inefficient decision making, insufficient communication, uncertain site conditions, a continuously changing environment, inharmonious working relationships, mismatched objectives within the project team and a blame culture. One approach to overcoming these problems appears to be to measure performance by gauging contractor satisfaction (Co-S) levels, but this has not been widely investigated as yet. Additionally, the key Co-S dimensions at the project level are still not fully identified. This paper concerns a study of satisfaction dimensions, primarily by a postal questionnaire survey of construction contractors registered by the Malaysian Construction Industry Development Board (CIDB). Eight satisfaction dimensions are identified that are significantly and substantially relate to these contractors - comprising: project cost performance, schedule performance, product performance, design satisfaction, site safety, project profitability, business performance and relationships between participants. -Each of these dimensions is accorded different priority levels of satisfaction by different contractors. The output of this study will be useful in raising the awareness and understanding of project teams regarding contractors' needs, mutual objectives and open communication to help to deliver a successful project.
