In this paper, to integrate distributed IT resources and manage human resource efficiently as purpose of cost reduction, infrastructure of wind turbine monitoring system have been designed and developed on the basis of SaaS cloud. This infrastructure hierarchize data according to related task and services. Softwares to monitor conditions via the infrastructure are also developed. Softwares are made up of DB design, field measurement, data transmission and monitoring programs. The infrastructure is able to monitor conditions from SCADA data and additional sensors. Total time delay from field measurement to monitoring is defined by modeling of step-wise time delay in condition monitoring algorithms. Since vibration data are acquired by measurements of high resolution, the delay is unavoidable and it is essential information for application of O&M program. Monitoring target is gearbox in wind turbine of MW-class and it is operating for 10 years, which means that accurate monitoring is essential for its efficient O&M in the future. The infrastructure is in operation to deal with the gearbox conditions with high resolution of 50 TB data capacity, annually.

This study was a descriptive investigation of the effects of nursing students' major satisfaction and professor-student interaction on their adjustment to university life. For this investigation, data were collected from July 22 to August 15, 2017. The collection was made through a questionnaire survey of nursing students in their 1st or 2nd year at one of eight colleges or universities located in B Metropolitan City, U Metropolitan City and G City. Participants were informed of the purpose of the study and agreed to participate in it. Of all the questionnaire sheets collected after the survey, those filled in by 205 participants were finally used for analysis here, with those by others excluded because they were considered to have been inappropriately filled out. The findings of this study can be summarized as follows. Nursing students surveyed in the study were significantly different from one another with respect to adjustment to university life depending on grade, health status, interpersonal relationships, desired career, academic achievement and family life level. Moreover, nursing students who had higher satisfaction with their major and more interactions with their professors were likely to adjust better to university life. In addition, regression analysis revealed that the nursing students' satisfaction with their major had the biggest effect on their adjustment to university life. Taken together, the results suggest that nursing students in their 1st or 2nd year of school should continue to be provided with curricular or extracurricular programs designed to improve their major satisfaction and that they should be given opportunities for communication with or counseling from their advisors or other nursing professors from the onset of university life.

This study was conducted to investigate the effects of workplace bullying and social support on turnover intention of nurses. The data included 133 nurses who worked in general hospitals in Chungchungbukdo. Data were collected from 1 November, 2016 to 25 December using self-report, structured questionnaires. Collected data were analyzed by ANOVA, t-test, Pearson correlation coefficient and multiple regression using SPSS 20.0. The results showed that the effects of workplace bullying and social support on turnover intention averaged 1.46 (out of 4), 3.55 (out of 5) and 3.30 (out of 5). Additionally, there was a significant positive correlation between workplace bullying and turnover intention (r=0.218, p=0.012) and negative correlations between social support and turnover intention (r=-0.363, p<0.001). Multiple regression analysis revealed that the predictors of turnover intension were education (${\beta}=-0.268$, p<0.009), total clinical experience (${\beta}=0.706$, p<0.001), and workplace bullying (${\beta}=0.183$, p<0.036). Based on these results, it is necessary to recognize the importance of workplace bullying and develop and adapt programs to reduce workplace bullying in order to decrease turnover intention among nurses.

This study identifies interest and reasons for small- and medium-sized technological firms to increase their uses of Technopark for product innovation and development. To determine whether interest exists, a research model was built, based upon the innovative process that small and medium sized enterprises'experience when developing capabilities. The model was characterized by its entrepreneurial orientation, organizational culture and support of the Technopark. Small and medium-sized technological firms operating in Technopark were surveyed in the Fall of 2019. Responses were collected and analyzed using structural equation modeling. Among the findings: supporting greater uses of Technopark can impact a firm's performance positively by mediating new product development capabilities. Firms with relatively limited resources and capabilities are most likely to benefit from using regional innovation hubs such as Technopark to improve their innovative capabilities and performance. Government and Technopark need to develop and implement demand-based support programs, especially ones to focus on improving the innovation capabilities of technology-based small and medium-sized enterprises.

This study is conducted to evaluate the supply effectiveness of the Long-term Secured Public Rental Housing (LSPRH) program implemented by the City of Seoul since March, 2012. To estimate the residential intention of potential applicants for the housing program, two logistic regression models of residential intention are estimated based on the residential characteristics of real residents. The purpose of this model estimation is to find out factors influencing the supply of LSPRH and thus to suggest the ideas for improving the effectiveness of the rental housing program operation. The analysis result shows that financial condition, income level, and public support are the major determinants for selecting LSPRH. It is also revealed that those who are currently living in rental housing or living in a house more expensive than those in nearby areas have higher residential intention for the LSPRH program. The result also presents that some problems associated with the traditional rental housing programs - such as visually recognizable low-quality exterior building design or the concentration of rental housing on limited spots - could be solved by this new type of public housing program. Lastly, one interesting finding different from previous research is that people with the intention to move into either traditional rental housing or LSPRH do not necessarily prefer a more spacious house than their current rental house.

Objectives: Weight control practices are common in combat sport athletes. This study was performed to examine nutrient intakes of male college combat sport athletes (taekwondo, boxing, judo) by weight control (WC) status. Methods: Subjects were male combat sport athletes (n=90) from colleges in Gyeonggi Province. Survey was conducted during 2016. Questionnaire included general characteristics, weight control, and dietary intakes during the period of training, weight control, weigh-in ~ before competition and between competitions. Subjects were grouped into high- and normal WC groups. T-test, ${\chi}^2-test$, Fisher's exact test and ANCOVA were used to analyze the data. Results: During training, energy intake was 75.4% of EER and C:P:F ratio was 57.5:13.9:28.7. Iron and zinc intakes were different by WC groups (p<0.05). During weight control, energy intake was 44.7% of EER in normal WC and 30.5% in high WC group (p<0.05). C:P:F ratio was 69:11.1:19.5, and ratio from protein and fat was lower in the high WC group (p<0.05). Most nutrient intakes during weight control were less than 50% of 2015 KDRIs (RNI or AI), and intakes including thiamin (p<0.01), vitamin A, riboflavin, niacin, folate, calcium, potassium and zinc (p<0.05) were significantly lower in the high WC. Energy intake after weighing before the competition was 1,315 kcal, and energy (kcal/kg BW, p<0.05) and carbohydrate intakes (g/kg BW, p<0.01) were significantly higher in the high WC group. Energy intake between competitions was 691.1 kcal, with no difference by the WC group. Conclusions: Nutrients intakes of combat sport athletes were inadequate. Dietary intakes during weight control were much below than the KDRIs, especially in the high WC group. It is needed to develop nutrition education programs for combat sport athletes to avoid severe energy restrictions and to apply specific dietary guides to each period of training and weight control.
