We evaluated a commercial biopreparation of plant growth-promoting rhizobacteria (PGPR) strains Bacillus subtilis GB03 and B. amyloliquefaciens IN937a formulated with the carrier chitosan (Bio Yield) for its capacity to elicit growth promotion and induced systemic resistance against infection by Cucumber Mosaic Virus (CMV) and Pseudomonas syringae pv. tomato DC3000 in Arabidopsis thaliana. The biopreparation promoted plant growth of Arabidopsis hormonal mutants, which included auxin, gibberellic acid, ethylene, jasmonate, salicylic acid, and brassinosteroid insensitive lines as well as each wild-type. The biopreparation protected plants against CMV based on disease severity in wild-type plants. However, virus titre was not lower in control plants and those treated with biopreparation, suggesting that the biopreparation induced tolerance rather than resistance against CMV. Interestingly, the biopreparation induced resistance against CMV in NahG plants, as evidenced by both reduced disease severity and virus titer. The biopreparation also elicited induced resistance against P. syringae pv. tomato in the wild-type but not in NahG transgenic plants, which degrade endogenous salicylic acid, indicating the involvement of salicylic acid signaling. Our results indicate that some PGPR strains can elicit plant growth promotion by mechanisms that are different from known hormonal signaling pathways. In addition, the mechanism for elicitation of induced resistance by PGPR may be pathogen-dependent. Collectively, the two-Bacilli strain mixture can be utilized as a biological inoculant for both protection of plant against bacterial and viral pathogens and enhancement of plant growth.

Purpose: This study attempted to access the health promotion activities and employee's health promotion needs in workplaces. Methods: Subjects were 280 health care managers employed at small to large scale enterprises in national-wide areas of Korea. The instrument was a structured questionnaire included characteristics of workplace and respondents, health promotion activities, health promotion needs, and bottlenecks to operate programs. Data was analyzed using SAS 8.1 by applying $x^2-test$, t-test and ANOVA. Results: 1, 25.4% of the total workplaces employed health care managers. 2. Musculoskeletal management programs(49.6%) were the highest operating program. 3. The highest needs of health promotion programs were lifestyle management and disease prevention. 4. Health promotion activities were significantly different according to the type and size of workplaces. The programs were more frequently applied in manufacturing industries than non-manufacturing and in large-scale enterprises than small and middle-scale enterprises. 5. The needs of health promotion programs were high in non-manufacturing industries than manufacturing industries in all programs. 6. The major bottlenecks to operate programs were the difficulty in securing time, lack of budgets and lack of legal regulations. Conclusions: Health promotion activities were linked to their work environments including budgets, time, and law. Therefore, to operate effective health promotion programs in workplaces, various health promotion programs are required to be developed and systems for governmental support and management should be established.

Objective: This study was carried out to examine the factors affecting the fatigue and health promotion behavior of hairdressers and their respective levels. The data were collected from 195 hairdressers working in beauty shops in Daegu and Gyeongsangbuk-do Province using self-administered questionnaires over the period from July 1 to July 31. Methods: A multiple regression model was used to study the factors influencing fatigue and health promotion behavior among hairdressers. Results: This study showed a statistically significant difference in perceived fatigue levels and health promotion behavior according to age, family type, education level, work period, work position, and fatigue level in the past one week. In addition, multiple regression showed that statistically significant factors affecting perceived fatigue were education level, work period, and fatigue level in the past one week. Statistically significant factors affecting health promotion behavior were age and fatigue level in the past one week. The level of perceived fatigue among hairdressers tended to be higher than other workers, and their level of practice of health promotion behavior was generally lower. Conclusions: The improvement of the work environment, such as through the distribution of a proper workload considering workers' characteristics and strengthening of exercise programs to reduce the fatigue level and promote health practices among hairdressers is needed.

Objectives : To investigate the current status of hospital-based health promotion programs in Korea and to elucidate the factors which affect to the process of implementation. Methods : We conducted a mail survey of all 875 hospitals in Korea from March to May 2001. In reference to 12 specific kinds of health promotion programs, hospital CEOs were asked whether their hospital have such programs, whether they are fully staffed and whether the program is paid for by the patients. Contextual factors(location, hospital type, number of beds, length of operation, public/private status, economic level of the community, the level of competition) and organizational factors (the extent of market, compatibility with vision, formalization), strategic types of the CEOs (defender/analyser/prospector) were also surveyed. The relationships between each variable and the implementation of health promotion services, activation of services, and the target groups(patient/community resident) were analyzed by univariate analysis and the independent effects of these variables were examined with multiple logistic regression. Results : 100 of 125 hospitals responding (84.8%) had mere than one health promotion program. However, they showed fluctuations in the adoption rate of each programs, meaning that comprehensive health promotion services were not provided. Many programs were not fully staffed and few hospitals had paid programs. In factors affecting health promotion service implementation, private hospitals showed a higher rate in implementation than public hospitals. In contrast, when the competition among nearby hospitals was intense, the level of implementation of service lowered. In the strategic type of the CEOs, the prospectors were shown to have instituted more health promotion programs in their hospitals and the analysers had a greater tendency to have programs for community residents than the defenders. Conclusion . Considering the above results, contextual factors may contribute greatly to the introduction of health promotion services in Korean hospital, although the CEO's personal preference and organizational factors play a larger role in the activation of services. Additionally, the CEO's personal preference may be the major influencing factor in the introduction of programs for community residents.

Objectives: This study was performed to identify factors related to perceived health status among patients with type 2 diabetes. Methods: This is cross-sectional observational study. Respondents were 106 visitors in an outpatient diabetes clinic of a university hospital. Self-report questionnaire which included general information inquiry, diabetes-related, sociopsychological factors, functional health literacy and perceived health status was used for this study. The data was analyzed by using descriptive statistics, independent simple t-test, one-way ANOVA, and hierarchical multiple linear regression. All analysis were conducted using SAS 9.3. Results: Among the respondents, 43.4% engaged in poorly perceived health status. After adjusting for control variables, functional health literacy is significantly related to perceived health status(${\beta}$=0.095, p=0.016). Conclusion: Independent of diabetes-related, sociopsychological factors, higher functional health literacy is associated with better perceived health status of patients with type 2 diabetes. In order to improve perceived health status in the type 2 diabetes patients, it is necessary to develop strategy to enhance the functional health literacy.

In this study, a dwelling type of Korea and Japan was compared, and consumption rate of domestic timber and its usage was also investigated. In Korea, dwelling type of apartment which constructed by iron and steel-concrete is main shared, but a detached house which is shared at 60% of dwelling type of Japan is mainly constructed by timber. And the rate of the consumption of domestic wood in Japan is 73%. In Japan, there is an effort to substitute imported wood to domestic timber through the promotion of using of domestic timber. Whereas the needs on using of domestic timber gradually emerged. So, the legal about sustainable use of wood is approved by the National Assembly on May 2012. There is not active movement in the aspect of using of domestic timber yet. These causes to the geographical and environmental characteristics, but industry, policy, and the difference of recognize on domestic timber utilization is thought to do greater influence. Hence, it is recommended to make a portfolio of both balanced domestic timber usage and the change of awareness of people by referring to the example of Japan.

Objectives: The main purpose of this study was to examine factors associated with depression of middle school students in relation to self-esteem, type A behavior pattern, and locus of control. Methods: A survey was administered to a convenience sample of 309 middle school students. The data analysis procedure included frequency distribution, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression using depression as the dependent variable. Results: The prevalence of depression was 27.2%. Stepwise multiple regression revealed that the factors such as self-esteem(${\beta}$=0.422, p<0.001), type A behavior pattern(${\beta}$=0.166, p<0.001), and locus of control(${\beta}$=-0.165, p<0.001) turned out to be significant affecting factors. Forty nine percent of variance in depression was explained by these factors(40% of variance by self-esteem). Conclusions: The findings suggest that personal internalizing variables should be considered when developing mental health education program to prevent the occurrence of depression for middle school students.

This study was conducted to investigate the effects of heating, fiber type used in solid-phase microextraction (SPME, two phase vs three phase) and storage time on the volatile compounds of porcine M. longissimus dorsi (LD). Volatile compounds were measured using a gas chromatography and mass spectrometry (GC/MS) with a quadrupole mass analyzer. Among the volatile compounds identified, aldehydes (49.33%), alcohols (24.63%) and ketones (9.85%) were higher in pre-heated loins ($100^{\circ}C$/30 min), whereas, alcohols (34.33%), hydrocarbons (22.84%) and ketones (16.88%) were higher in non-heated loins. Heating of loins induced the formation of various volatile compounds such as aldehydes (hexanal) and alcohols. The total contents of hydrocarbons, alcohols, and carboxylic acids were higher in two phase fibers, whereas those of esters tended to be higher in three-phase fibers (p<0.05). Most volatile compounds increased (p<0.05) with increased storage time. Thus, the analysis of volatile compounds were affected by the fiber type, while heating and refrigerated storage of pork M. longissimus dorsi increased the volatile compounds derived from lipid oxidation and amino acid catabolism, respectively.

Objectives: This study was to examine the independent and mediating effect of socioeconomic position and social relationship on depression. Methods: The study analyzed the data from the 2014 Korea Welfare Panel Study(n=9,172) using descriptive statistics, Kendall's rank correlation analysis, multiple regression analysis and the Sobel test. Results: Much of the connection between parental socioeconomic position and respondent depression was explained by respondent educational attainment in men but was not in women. A large portion of the association between educational attainment and depression was explained by type of household and satisfaction with social relationship among men. The effect of educational attainment on depression was fully mediated by type of household among women. The effect of type of household on depression was partly mediated by satisfaction with social relationship in men and women. Lastly, educational attainment, type of household and satisfaction with social relationship had an independent association with depression among men, but educational attainment was not statistically significant among women. Conclusions: Our study illuminated the importance of the independent and mediating effect of parental and respondent socioeconomic position and social relationship in the production of depression for South Korean adults.
