Purpose: This article aimed to identify nurses' experience of practice in nursing homes. Method: Using phenomenological approach for qualitative research, the participants were 8 nurses who were working at nursing homse in C city. The data was analyzed by using phenomenological methodology by Colaizzi. Results: Five theme clusters were derived from the data. They were: burden (independent decision making in clinical situations, tension of as a multifunctional member); lowered self-esteem (exhaustion, relative self-evaluation is low, comparing with others); conflict (negative image of elderly, communication break with elderly family, monitoring of nursing home staff); worth (slight improvement of elderly health state, trust and recognition, intimacy); and self-reflection (need for knowledge extension, effort towards enhancing virtue, perception of importance in their health management). Conclusion: The results showed that nursing home nurses experienced negative aspects of various nursing practice, suggesting the ways to solve their negative experience.

Cellular manufacturing requires formation of machine cells that can produce families of parts with similar processing requirement. The purpose of cell formation is to create separable machine clusters and part families simultaneously. However, the cell formation process often includes the identification of exceptional elements. This paper presents cell formation method under consideration of alternative routings in FMS which consists of machines capable of multi-processing and parts which require more than one operation. We suggest theorems to calculate the maximum number of machine cell and part family which have no exceptional elements. We also develop a cell formation algorithm which is based on the suggested theorem. A numerical example is provided to illustrate the proposed theorem and algorithm.

To probe the genomic properties of microbes thriving in desert lakes, we sequenced the full genome of a betaproteobacterial strain (SL110) belonging to the understudied genus Caenimonas of the family Comamonadaceae. This strain was isolated from a freshwater lake in the western Gobi Desert, Northern China. Its genome contains genes encoding carbon monoxide dehydrogenase, nitrate reductase, nitrite reductase, nitric oxide reductase, and sulfur oxidation enzymes, highlighting the potentially important contribution of this group of bacteria to the cycling of inorganic elements in nature. Unexpectedly, a coenzyme $F_{420}$ biosynthesis gene cluster was identified. A further search for $F_{420}$ biosynthesis gene homologs in genomic databases suggests the possible widespread presence of $F_{420}$ biosynthesis gene clusters in proteobacterial genomes.

Gymnopilus spectabilis, a hallucinogenic mushroom belonging to the family Cortinariaceae, is found growing in dense clusters on stumps and logs of hardwoods and conifers. It contains the hallucinogenic alkaloid psilocybin and its strongly bitter taste makes it undesirable as an edible. In an effort to identify chemical constituents of Korean native wild mushrooms, 4,6-decadiyne-1,3,8-triol (1), ergosta-4,6,8(14), 22-tetraen-3-one (2), bisnoryangonin (3), and hispidin (4) were isolated from the methanolic extract of the fruiting bodies of G. spectabilis. Their structures were assigned on the basis of various spectroscopic studies. Compounds 3 and 4 displayed significant scavenging activity against the ABTS radical cation, DPPH radical, and superoxide radical anion, while 1 and 2 exhibited no antioxidant activity.

This research reviews the characteristics of consumption oriented culture of post modern society and describes the food consumption culture based on the evaluative criteria pattern in eating in Ulsan Metropolitan City. The subjects consisted in 217 full-time housewives and 129 cooks. The evaluative criteria of eating scale with 4 components - the eating atmosphere factor, the preference factor, the quality factor and the table factor- is described and interpreted in the context of consumption oriented culture. 4 clusters were decided through cluster analysis; preference and quality pursuing type, high involvement type, consumerism culture pursuing type and low involvement type. Among socio-economic variables, the evaluative criteria pattern of eating was significantly associated with occupation. The results of factor analysis and cluster analysis proved that the full-time house wives and cooks in Ulsan Metropolitan city showed the propensity to consumption oriented culture in food consumption culture.

The polyene antibiotics including nystatin, pimaricin, amphotericin and candicidin are a family of most promising antifungal polyketide compounds, typically produced by rare actinomycetes species. The biosynthetic gene clusters for these polyenes have been previously investigated, revealing the presence of highly homologous biosynthetic genes among polyene-producers such as polyketide synthase (PKS) and cytochrome P450 hydroxylase (CYP) genes. Based on amino acid sequence alignment among actinomycetes CYP genes, the highly-conserved regions specific for only polyene CYP genes were identified and chosen for degenerate PCR primers, followed by the PCR-screening with various actinomycetes genomic DNAs. Among tested several polyene non-producing actinomycetes strains, Pseudonorcardia autotrophica strain was selected based on the presence of PCR product with polyene-specific CYP gene primers, and then confirmed to contain a cryptic novel polyene hydroxylase gene in the chromosome. These results suggest that the polyene-specific hydroxylase gene PCR should be an efficient way of screening and isolating potentially-valuable cryptic polyene antibiotic biosynthetic genes from various microorganisms including rare actinomycetes.

Wolfiporia cocos is a wood-decay brown rot fungus belonging to the family Polyporaceae. While the fungus grows, the sclerotium body of the strain, dubbed Bokryeong in Korean, is formed around the roots of conifer trees. The dried sclerotium has been widely used as a key component of many medicinal recipes in East Asia. Wolfiporia cocos strain KMCC03342 is the reference strain registered and maintained by the Korea Seed and Variety Service for commercial uses. Here, we present the first draft genome sequence of W. cocos KMCC03342 using a hybrid assembly technique combining both short- and long-read sequences. The genome has a total length of 55.5 Mb comprised of 343 contigs with N50 of 332 kb and 95.8% BUSCO completeness. The GC ratio was 52.2%. We predicted 14,296 protein-coding gene models based on ab initio gene prediction and evidence-based annotation procedure using RNAseq data. The annotated genome was predicted to have 19 terpene biosynthesis gene clusters, which was the same number as the previously sequenced W. cocos strain MD-104 genome but higher than Chinese W. cocos strains. The genome sequence and the predicted gene clusters allow us to study biosynthetic pathways for the active ingredients of W. cocos.

Purpose: The purpose of the study was to understand and explain the essences and structures of the experience of Korean women who have had a spinal cord injury. Methods: The data were collected in 2010 through individual in-depth interviews using open-ended questions. A total of 9 women with spinal cord injuries participated in the study. Each interview lasted about 2 hours. Verbatim transcripts were analyzed using phenomenological analysis. Results: Five theme clusters emerged from the analysis using Colaizzi's method: frozen mind with rigid body; shame due to restrictions of physical function and dependency; struggle to go back to the previous normal body; disabilities that are noticeable in everyday family life; rebirth by discarding the obsessions of the past. These theme clusters illustrate that although most participants faced very strange and unbearable situations in most aspects of life after the injury, they were empowered finally by finding their hope and by giving new meanings to the current existence. Conclusion: This study provides deep understanding of women with spinal cord injuries who are relatively alienated from society. Based on the results of the study, health professionals could develop effective nursing interventions to improve quality of life of these women.

The purpose of current study was to find differences of selected attributes and visitors of responses according to their lifestyle as perceived by Pocheon Yidong-BBQ-Galbi Festival participants. Survey method was employed and total 370 data was used for statistical analysis. The results of factor analysis showed that three factors were extracted from lifestyle(Activity, Example, Commonness), and four factors were found from festival selection attribute(Food, Service, Program, Cleanliness). In addition, three clusters(Outgoing personality, Gentle character, Normal character) were extracted from the result of cluster analysis. The result of chi-square shows that selection attributes are significantly different by clusters of festival. Therefore the festival host need to focus on various kinds of BBQ along with diverse foods and activities to make attractive cultual experience festival for visitors who visited with family. Additionally, all selection attributes except clearness have significantly influence on responsive relationship. Thus, the organizer should make an effort to provide high quality of various selection attributes. Current study will be contribute to develop various and fascinating local festival expecially related to food.
