Streptomyces albidoflavus C247 was isolated from the soil of the Gyeongsan golf course in Korea. Physiological, biochemical and 16S rDNA gene sequence analysis strongly suggested that the isolate belonged to Streptomyces albidoflavus. Preliminary screening revealed that the isolate was active against fungi and bacteria. Self-directing optimization was employed to determine the best combination of parameters such as carbon and nitrogen source, pH and temperature. Nutritional and culture conditions for the production of antibiotics by this organism under shake-flask conditions were also optimized. Maltose (5%) and soytone (5%) were found to be the best carbon and nitrogen sources for the production of antibiotics by S. albidoflavus C247. Additionally, 62.89% mycelial growth inhibition was achieved when the organism was cultured at $30^{\circ}C$ and pH 6.5. Ethyl acetate (EtOAc) was the best extraction solvent for the isolation of the antibiotics, and 100 ${mu}$/ml of EtOAc extract was found to inhibit 60.27% of the mycelial growth of Rhizoctonia solani AG2-2(IV) when the poison plate diffusion method was conducted.

Purpose: The aim of this study was to identify awareness and competency for Multi-Drug Resistant Organisms (MDRO) infection control in nursing students with experience of clinical practice. Methods: This cross-sectional descriptive study was conducted from March 2019 to May 2019 by including 231 nursing students in four nursing schools located in Seoul, Gyeonggi-do and Chungcheongnam-do. The data were collected using self-report questionnaires. Results: The awareness and the competency for Carbapenem-Resistant Enterobacteriaceae (CRE) infection control were lower than that of Methicillin-Resistant Staphylococcus aureus (MRSA). The agreement between the awareness and the competency of MDRO infection control in participants was low with regard to isolation, contact precautions, and disinfection for MRSA. Also, it was low with respect to disinfection, isolation, contact precautions, and carrier identification for CRE. The awareness and the competency of MDRO infection control exhibited significant positive correlation. Conclusion: The infection control competency is required to prevent MDRO infection. In order to enhance the infection control competency, it is important to raise awareness about MDRO infection control by providing education based on the guidelines and the principles of infection control.

With an annual growth rate of about 30%, wind energy systems, such as wind turbines, represent one of the fastest growing renewable energy technologies. Continuous structural health monitoring of wind turbines can help improving structural reliability and facilitating optimal decisions with respect to maintenance and operation at minimum associated life-cycle costs. This paper presents an integrated monitoring system that is designed to support structural assessment and life-cycle management of wind turbines. The monitoring system systematically integrates a wide variety of hardware and software modules, including sensors and computer systems for automated data acquisition, data analysis and data archival, a multiagent-based system for self-diagnosis of sensor malfunctions, a model updating and damage detection framework for structural assessment, and a management module for monitoring the structural condition and the operational efficiency of the wind turbine. The monitoring system has been installed on a 500 kW wind turbine located in Germany. Since its initial deployment in 2009, the system automatically collects and processes structural, environmental, and operational wind turbine data. The results demonstrate the potential of the proposed approach not only to ensure continuous safety of the structures, but also to enable cost-efficient maintenance and operation of wind turbines.

Objectives: This study was designed to construct and test the structural equation model for the alcohol-related problem of alcohol use disorders. Methods: Data were collected by structured self-questionnaires from 229 male subjects who received > 8 (greater than 8) score on Alcohol Use Disorder Identification Test (AUDIT). The Data were analyzed by SPSS 21.0 and AMOS 21.0. Results: The model fit indices for the modified hypothetical model showed Q = 2.50, GFI = 0.90, and CFI = 0.94. As a result, Life position, parent's drinking problem, and alcohol expectancy had significantly direct effect on alcohol-related problem. Alcohol expectancy also had mediator effect between life position and alcohol-related problem. Conclusions: Consequently, the more positive life position, the less alcohol-related problem occurred. It is necessary to change their life position, which is individual factor, to prevent or reduce the alcohol related problem of alcohol use disorders.

Purpose: This research was done to identify relationships among job stress, fatigue, job satisfaction, and commitment to organization in emergency department nurses. Methods: Research participants were 513 nurses who worked in the emergency department of 17 tertiary centers and 28 secondary hospitals. Data collection for this descriptive correlational study was done from May to July 2010 using self report questionnaires, and analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient with the SAS 9.2 program. Results: There were statistically significant differences in organizational commitment according to age, religion, total clinical experience, emergency department experience, current position, frequency of night shift, average sleep hours, wage level, numbers of beds in unit, and reason for working. A positive correlation was found between job stress and fatigue, and between job satisfaction and commitment to organization for the emergency department nurses and a negative correlation between job stress and Job satisfaction, and fatigue and Job satisfaction. Conclusion: Results of this research indicate that job stress in emergency department nurses was the principal variable affecting job satisfaction and commitment to organization along with fatigue. Appropriate stress management strategies based on identification of job stress for these nurses should lead to development of improved management of nursing manpower and a reduction in stress.

This study intends to present the directions for effective up-cycling design using Marquage painting through analysis of trends and the formative characteristics of fashion products. Research was conducted through a literature review (published papers, books and web site contents). Cases were analyzed by examining the contents of web sites of global luxury brands, representative workshops, and social network sites (SNS). The results of the study are categorized as follows, First, Marquage paintings are continuously used by global luxury brands and have developed as an expression of self-ownership and the personalization of one's identity. Second, fashion brands use Marquage painting as a customized service for sales. On the other hand, Marquage paintings are used as a kind of up-cycling to present old goods as brand new ones. Third, the patterns used in Marquage painting were classified into five types: geometric patterns, logo patterns, character patterns, lettering patterns, and art patterns. Moreover, formalization by Marquage patterns is represented by identification, customization, and up-cycling. Finally, to up-cycle the expressive features of Marquage- sustainability, scarcity, storytelling, and originality based on factors of up-cycling need to be reflected.

A Bayesian dynamic linear model (BDLM) is presented for a data-driven analysis for response prediction and load effect separation of a revolving auditorium structure, where the main loads are self-weight and dead loads, temperature load, and audience load. Analyses are carried out based on the long-term monitoring data for static strains on several key members of the structure. Three improvements are introduced to the ordinary regression BDLM, which are a classificatory regression term to address the temporary audience load effect, improved inference for the variance of observation noise to be updated continuously, and component discount factors for effective load effect separation. The effects of those improvements are evaluated regarding the root mean square errors, standard deviations, and 95% confidence intervals of the predictions. Bayes factors are used for evaluating the probability distributions of the predictions, which are essential to structural condition assessments, such as outlier identification and reliability analysis. The performance of the present BDLM has been successfully verified based on the simulated data and the real data obtained from the structural health monitoring system installed on the revolving structure.

This article aims to describe the institutional structuring strategy of independent smallholders in accelerating sustainable economic development, by taking the example of the cow-coconut integration system (SISKA) problem in Sialang Palas Village, Riau. The method used identified stakeholders related to SISKA; the stakeholder's goals and interests, farmers' social and institutional bases, and self-help farmer socio-economic networks. First, identification of various factors through strengths, weaknesses, opportunities, and threats (SWOT) analysis techniques. Second, through the Modern Political Economy analysis technique. Third, imparting knowledge and skills to the farmers and village officials through a collective learning process in utilizing natural resource waste and social resources. The results showed that the farmer management strategy in the reform era started by clustering the interests of farmers. The dynamics of structuring group relations between the chairman and members with farmers outside the group are the basis for strengthening the local ideology of independence in the future. This institutional structuring strategy that focuses on access to farm power in the village decision-making process encourages a more integrated work of farmer organizations. The analysis above shows that the independent smallholder institutional engineering through regulation, organization, and resources are determined by the farmer household economic factors and the application of the value of local wisdom.

This essay examines the first-generation Korean American writer, No-Yong Park's falsehoods about his ethnic identity to suggest how and why he passed for Chinese, and to explore the political, anti-Japanese implications of these actions. The essay first identifies erroneous information circulating about his biographical background, presents some other materials that help us better understand the context in which he forged his Chinese identity, and then examines how he represented himself as Chinese in his published works. I would argue that Park's self-identification as Chinese was a resulting outcome of his naturalization caused by the Japanese colonial power in Korea and also one of his surviving strategies in the racist environment within American society. Looking at some of his works-including Making a New China (1929), An Oriental View of American Civilization (1934), Chinaman's Chance: Autobiography (1940)-and examining how he represented Korea and its people reveal how he tried to raise voice for them. By doing so, this essay illuminates Park's resistance to Japan's colonial discourse and power in Korea while revealing his lifetime passing as Chinese-far from his refusal to belong to the Korean community, or to acknowledge being Korean.
