The statistics of industrial accident reported by ministry of Employment and Labor denoted a significant increase of musculoskeletal disorders(MSDs) after 1993, and showed the higher incident rate by 71.3% over the overall worker's disorders. Also, it was expected that Korean society will become the post-aged society in 2026 with 20.8% of elderly who is over 65 years old. The reports suggest possible problems caused by the older worker known to have reduced working ability than the young counterparts. On this basis, the goal of this study was to investigate the relationship between MSDs symptoms and work ability in the shipbuilding industry. To achieve this goal, this study distributed a questionnaire for total 1,244 shipbuilding employers, and used 910 employers' reports which revealed validity for this study. The questionnaire included the MSDs symptoms report developed by the Korean Occupational Safety and Health Association(KOSHA) and the work ability index(WAI) developed by Finnish Institute of Occupational Health(FIOH). Results showed no relationship between MSDs symptoms and age, years of work and exercise. Also, the work ability was increased until 44 years old, but it was decreased after that time because of the reduced physical capacity. Meanwhile, the years of work and exercise have positive correlation with work ability. However, the results revealed significant relationships between WAI and age, years of work, task characteristics and exercise. All together, the MSDs symptoms have a close relationship with the work ability in that the work ability of workers with the MSDs symptoms was reduced. This study may suggest the needs of more efforts and attention on the MSDs prevention to increase the work ability.

This study examined the influence of patient safety culture and safety care activities of general hospital nurses. The participants were 178 nurses working in a hospital in D and G cities. Data were collected from June to July, 2015 through Questionnaires that included the Measure of Patient Safety Culture by Kim et al.(2007), and the Measure of Safety Care Activities by Lee(2009). The collected data were analyzed by descriptive analysis, t-test, One-way ANOVA, Pearson correlation coefficients, and stepwise Multiple regression. A statistically significant positive relationship was observed between the nurses perception of the patient safety culture and their safety care activities (r=.407, p<.001). The findings show the patient safety culture accounted for 43.3% of the variance in the safety care activities for hospital nurses followed by the importance of hospital work environment among nurses to improve the safety care activities. These findings highlight the need to develop effective programs to improve the perception of patient safety culture and safety nursing guideline.

We examine the relationship between firms' environmental (E), social (S), and governance (G) factors, with their financial performance in order to provide an empirical rationale for CSV (creating shared value) pursuing both of firms' profitability and CSR (corporate social responsibility). The financial performance is classified into four aspects such as profitability, stability, efficiency, and cash-flow, and each of these aspects is measured by two financial ratios respectively. To measure the firms' ESG performance, we employ the published performance grades by the Korea Corporate Governance Service for a three year span, from 2011 to 2013. Total of eight regression analyses are performed. The results show that firms' non-financial performance in general has statistically significant positive relationships with return on assets, return on net sales, and cash-flow from operating activities ratio, while it has negative relationships with net working capital ratio, asset turnover ratio, and cash-flow from investing activities ratio. It has no significant relationships with debt ratio and equity turnover ratio. The results imply that firms' non-financial performance may have a negative impact on some financial performance such as liquidity and efficiency in a short term, but it would eventually improve the firms' profitability and cash-generating ability, which provides an empirical evidence for the concept of CSV, and motivates the firms to participate in social contribution activities without sacrificing their profitability for their respective sustainablity management.

This study was conducted to examine the relationship between pre-service early childhood teacher's motivations of choosing a teaching profession, educational belief, and self-directed learning readiness. The sample included 308 early childhood education major students, and the data were collected using the Modified Orientation to Teach Survey (MOTS), Teaching-belief type scale, and self-directed learning readiness scale. A statistical analysis included correlation analysis and stepwise multiple regression analysis. The results were as follows: 1) analysis of the relationship between pre-service early childhood teacher's motivations of choosing a teaching profession, educational belief, and self-directed learning readiness conveys that intellectual stimulation and self-directed learning had the strongest relationships while nature of work had the weakest. For educational belief and self-directed learning readiness, maturationism and interactionism showed significantly positive correlations while behaviorism displayed a negative correlation. Behaviorism had a significantly negative correlation with openness for challenge, a sub-factor of self-directed learning. 2) Analysis of the effect of pre-service early childhood teacher's motivations of choosing a teaching profession and educational belief on self-directed learning readiness indicates that pre-service early childhood teacher's motivations of choosing a teaching profession had a stronger effect on self-directed learning. These results suggest the following: successful performance as an early childhood teacher not only requires receiving institutionalized education but also self-directed learning while working as an early childhood teacher.

From responses to individual written survey questionnaires answered by 608 students who are studying Dental Hygiene at colleges in Mokpo, Iksan, Gangneung. The following are the results regarding their satisfaction levels with their majors and their interest in working abroad: 1. Regarding the motivating factors to major in Dental Hygiene, most students(51.3%), particularly most freshmen(57.3%), have chosen this major because of more job opportunities than students with other majors. The most common source of information in choosing majors is the Internet(30.8%). 2. Most students do not want to change their majors even if they are provided with the chance to do so(65.5%). They are in general satisfied with their studies. The result shows that the Dental Hygiene majors are positive toward their major. 3. Most students will choose their jobs by their own choices(40.6%), and the most important factor in their choices is the opportunity of self-growth and development(33.1%). The survey results show that the Dental Hygiene students value their own decisions and self-realization. 4. Showed the difference that as a result of having seen a knowledge degree advance a school subject of major in Dental Hygiene by a school year and ash students, an admission motive, relevance of an information acquisition path, all noted. 5. And were able to see the difference that noted in an adviser, work selection bases in case of work selection whether or not there was a dissatisfaction reason about a major and a criminal record.

Outbreaks of staphylococcal food poisoning (SFP) causing serious human diseases and economic losses have been reported globally. Furthermore, the spread of Staphylococcus aureus with increased resistance to multiple antimicrobial agents has become a major concern in the food industries and medicine. Here, we isolated an endolysin LysSAP8, as one of the peptidoglycan hydrolases, derived from the bacteriophage SAP8 infecting S. aureus. This endolysin was tagged with a 6×His at the C-terminal of the target protein and purified using affinity chromatography. LysSAP8 demonstrated lytic activity against a broad spectrum of bacteria, which included a majority of the staphylococcal strains tested in this study as well as the methicillin-resistant S. aureus (MRSA); however, no such activity was observed against other gram-positive or gram-negative bacteria. Additionally, LysSAP8 could maintain bactericidal activity until 0.1 nM working concentration and after heat treatment at 37℃ for 30 min. The ability of LysSAP8 to lyse cells under varying conditions of temperature (4-43℃), pH (3-9), and NaCl concentrations (0-1,000 mM), and divalent metal ions (Ca²⁺, Co²⁺, Cu²⁺, Mg²⁺, Mn²⁺, Hg²⁺, and Zn²⁺) was examined. At the optimized condition, LysSAP8 could disrupt approximately 3.46 log CFU/ml of the planktonic cells in their exponential phase of growth within 30 min. In this study, we have suggested that LysSAP8 could be a potent alternative as a biocontrol agent that can be used to combat MRSA.
