This study was conducted to understand the role of soybean pathogenesis-related 10 (GmPR10) gene in salt tolerance and to develop salt-tolerant rice using GmPR10 cDNA. GmPR10 transgene was expressed constitutively in the shoot and root of the $T_1$ transgenic rice plants. Interestingly, however, the levels of the transgene expression were increased temporally up to over four- to five-fold in the shoot and root by 125 mM NaCl treatment, peaking at six hours after the treatment and decreasing thereafter. Electrolyte leakage of leaf cells under 125 mM NaCl treatment was lower in all the transgenic lines than in the control variety, Dongjin-byeo. Ability of seedlings to recover from 125 mM NaCl treatment for two weeks was higher in the transgenic plants than in the control plants. These results demonstrated that GmPR10 had function to increase cell integrity and promote growth under the saline stress imposed by NaCl. The transgenic line GmPR10-3 which showed highest ability to recover from the saline stress could be used as a potential source for salt tolerance in rice breeding programs.

Normal soybean seed contains three lipoxygenase isozymes called L-1, L-2, and L-3, respectively, which are responsible for the generation of undesirable grassy-beany flavors. Simple and effective methods for the detection of lipoxygenase isozymes were developed in soybean seeds. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) has been tried in separating these isozymes. It was done effectively on 7.5% separating gel and 4.5% stacking gel. However, no reliable method has been developed specifically for separating L-3, L-13 and L-23. Visual judging methods were based on the bleaching activities of lipoxygenase in contact with methylene blue and ${\beta}$-carotene. Sodium linoleate bleaching method was adopted to determine L-1 and L-2. Carotene bleaching and spectrophotometric methods were used to determine L-3. These systems were very rapid within one minute, furthermore only required a small piece of cotyledon (below 10 mg) and the other part could be used for generation advance after analysis. It was demonstrated that 200 seed samples could be analyzed per day by one laboratory assistant. The combination of visual judging methods and electrophoresis is suitable for breeding programs. It took 6.5 hours for analysis of 100 seed samples by one person.

Sleep quality among university students is important, especially for their physical and psychosocial wellbeing. This study was conducted to investigate the level of smartphone addiction and stress among university students, and to estimate the effects of those variables on sleep quality. Data were collected from August 1st to 14th, 2018 using an online self-report survey to measure demographics including daily activity and indulgence foods, smartphone addiction, perceived stress scale, and the Pittsburgh Sleep Quality Index (Korean version). Collected data were analyzed by independent t-tests, ANOVA, Pearson's correlation coefficients, and multiple regression. The results showed that smartphone addiction, stress, and sleep quality had positive correlation in each relation. Multiple regression analysis showed that the predictors of sleep quality were smartphone addiction (${\beta}=0.041$, p=.001) and stress level (${\beta}=0.177$, p=.001), and the regression equation explained 24.9% of sleep quality. Therefore, higher levels of smartphone addiction and stress were associated with lower sleep quality. Based on these results, it is necessary to reduce unnecessary use of smartphone usage, as well as to develop and apply programs for university students to improve their sleep quality.

The purpose of this study was to identify factors associated with character of nursing students using ecological theory. A descriptive cross-sectional study was conducted with 296 nursing students. Collected data from self report questionnaires were analyzed using descriptive statistics, t-test, ANOVA and multiple regression with SPSS WIN 21.0. The Results of this study were as follows. A total of 2 models were examined according to individual, microsystem in ecological system theory. In the first model including individual factors, positive emotion, communication ability were significant factors explain character of nursing students. In the second model adding micro system factors family strength and major satisfaction found to be significant factors. The prediction factors of nursing student' character were communication ability (${\beta}=.431$, p<.001), major satisfaction (${\beta}=.310$, p<.001) and family strength (${\beta}=.176$, p<.001). The explanation power was 55.6%. These results showed that factors affecting character of nursing students are communication ability, major satisfaction, and family strength. Therefore, we suggest to develop various character education programs considering these factors.

The purpose of this study was to analyze work complexity, critical thinking disposition, and the degree of intuition for nurse practitioners and determine the associations among the variables. 150 nurses at hospitals and general hospitals in D City participated in this study and data collection was performed from June 15 to July 8, 2017. The data were processed by using SPSS WIN 24.0 to estimate the mean, standard deviation and Pearson's correlation coefficient and perform one-way ANOVA. They scored $2.33{\pm}.45$ for work complexity, $3.58{\pm}.36$ for critical thinking disposition, and $2.69{\pm}.52$ for intuition. Work complexity differed significantly by age (F=4.55, p=.012), education (F=11.61, p=<.001), department (F=26.69, p=<.001), and clinical career (F=4.30, p=.006) among their general characteristics. Critical thinking disposition differed significantly by education (F=5.25, p=.006) and position (F=5.35, p=.006) and differed statistically insignificantly by intuition. Work complexity was positively correlated with critical thinking disposition (r=.323, p=<.001) and intuition (r=.201, p=.013) and no significant correlation was found between critical thinking disposition and intuition (r=.033, p=.685). On the basis of these results, it is necessary to develop education and programs that can allow nurses who regard nursing work as complex to improve their critical thinking disposition and intuition.

One of the key factors of a safe workplace is to communicate with the workers about safety. For this, natural gas workplace is developing and operating related programs or communication activities. But, if there are silence behavior of the workers on the safety issues in this process, no positive outcomes could be expected for the workplace. The purpose of this study is to examine how safety silence motives, silence behavior, and safety communication influence each other. A total of 233 questionnaires based on the workers of natural gas workplace (in Seoul and Gyeonggi) were analyzed. The confidence analysis is to check consistency of the questions, analysis of the correlations between factors, and regression analysis to verify the hypotheses. As a result, the safety silence motives affected safety communication more seriously than the silence behavior did. Safety communication influenced safety silence motives more significantly than the silence behavior. The safety silence motives can be one of the reasons for safety communication to fail, and it was confirmed that a good safety communication does not necessary mean that there is no safety silence motivation. Based on such results, it is expected that improving and developing the safety communication activities of the workplace, it would improve safety in workplace in general.

This study has empirically analyzed how far corporate governance and CSR(Corporate Social Responsibility) fit are related based on prior research indicating that corporate governance is one of the primary factors. Previous research suggested that there may be different types of CSR fit, but there have been only limited number of empirical studies. This study filled this gap by categorizing CSR fit into three types (functional fit, target fit, and size fit) and investigating whether different types have different effects. We used data from the Corporate Social Responsibility White Paper for the 2009-2012 period, as well as the Korea Corporate Governance Service (KCGS) index. As a result, we found that there is a negative (-) relationship between corporate governance and CSR fit(${\beta}=-.023$, p<.05). This can be interpreted that companies with weak corporate governance are attempting to increase the trust level of stakeholders and to reduce the uncertainty of CSR through high-CSR-fitted programs. The test results showed that functional fit and target fit both had negative (-) relationships with corporate governance (${\beta}=-.021$, p<.05; ${\beta}=-.016$, p<.1), while size fit did not have a significant correlation with corporate governance (${\beta}=-.005$, p=.511). The results of this study supported the previous studies' suggestions that CSR fit has different effects on each type, indicating a need for further reflection on the relationship between corporate governance and CSR fit. Also, the results of this study showed that corporations should take a strategic approach to operating CSR fit.

Meteorological factors and air pollutants are associated with respiratory diseases, and appropriate use of weather and air quality information is helpful in the management of patients with such diseases. This study was performed to investigate both the utilization of weather and air quality information by, and the needs of, patients with respiratory diseases. Questionnaires were administered to 112 patients with respiratory diseases, 60.7% of whom were female. The rates of bronchial asthma and chronic obstructive pulmonary disease among patients were 67.0% and 10.7%, respectively. The majority of subjects (90%) responded that prevention was important for respiratory disease management and indicated that they used weather and air quality information either every day or occasionally. However, respondents underestimated the importance of weather and air quality information for disease management and were unaware of some types of weather information. The subjects agreed that respiratory diseases were sensitive to weather and air quality. The most important weather-related factors were diurnal temperature range, minimum temperature, relative humidity, and wind, while those for air quality were particulate matter and Asian dust. Information was gleaned mainly from television programs in patients aged 60 years and older and from smartphone applications for those below 60 years of age. The subjects desired additional information on the management and prevention of respiratory diseases. This study identified problems regarding the utility of weather and air quality information currently available for patients with respiratory diseases, who indicated that they desired disease-related information, including information in the form of action plans, rather than simple health- and air quality-related information. This study highlights the necessity for notification services that can be used to easily obtain information, specifically regarding disease management.
