Purpose: This study was aimed to identify the level of emotional labor, job stress and professional quality of life and to identify the factors affecting on professional quality of life among nurses in long-term care hospitals. Methods: 136 nurses working at eight different long-term care hospitals were recruited from May 1 to June 30, 2016. Data were analyzed by descriptive statistics, t-test, ANOVA, Pearson correlation, and stepwise multiple regression using SPSS/WIN 22.0. Results: Professional quality of life is consisted of three subcategories as compassion satisfaction, secondary traumatic stress and burn-out. As for the factors affecting on compassion satisfaction, age, satisfaction on working ward and shift pattern of duties were significant factors. The three variables' explanation power on compassion satisfaction was 25.0%. As for factors affecting on secondary traumatic stress, emotional labor was a significant factor. The emotional labor's explanation power on secondary traumatic stress was 13.0%. Factors affecting on burn-out, emotional labor, age, and health condition were significant factors. The three variables' explanation power on burnout is 31.0%. Conclusion: On the basis of results, program development are required to relieve emotional labor and job stress for nurses at long-term care hospitals and to improve their professional quality of life.

The purpose of this study was to investigate the daily stress and stress coping behavior of elementary school children. The subjects for this study were 372 children fourth, fifth and sixth graders from an elementary school in Pusan. We adopted Won - Joo Chung's research instrument (1997) for measuring stress and coping behavior in this study. Statistical techniques such as frequency, percentage, mean, standard deviation, order, and Pearson correlation were used to examine the research questions of this study. The results of this study were as follows: 1. The most common instance of stress to be experienced by all children was the stress from school life, followed by social pressures, individual pressures and family environment. 2. A positive revaluation was the most commonly used stress-coping behavior, followed by behavioral mood conversion, spiritual support, problem-facing behavior, an information search for problem-solving, physical separation for emotional relaxation, avoidance, emotional aggressiveness and emotional expression. 3. Stress-coping behavior had a positive and significant correlation with the stress score(r = .4391, p= .000). In conclusion, the stress from school life was the most common experienced by all children. While independent effort in problem-solving was unsufficient, stress coping behavior had positive results. Therefore, this study verified the necessity of minimizing the stress children experience from school life and of helping them attain desirable stress-coping behaviors.

Although doxorubicin (Dox)-induced oxidative stress is known to be associated with cytotoxicity, the precise mechanism remains unclear. Genotoxic stress not only generates free radicals, but also affects actin cytoskeleton stability. We showed that Dox-induced RhoA signaling stimulated actin cytoskeleton alterations, resulting in central stress fiber disruption at early time points and cell periphery cortical actin formation at a later stage, in HeLa cells. Interestingly, activation of a cofilin phosphatase, chronophin (CIN), was initially evoked by Dox-induced RhoA signaling, resulting in a rapid phosphorylated cofilin turnover leading to actin cytoskeleton remodeling. In addition, a novel interaction between CIN and $14-3-3{\zeta}$ was detected in the absence of Dox treatment. We demonstrated that CIN activity is quite contrary to $14-3-3{\zeta}$ binding, and the interaction leads to enhanced phosphorylated cofilin levels. Therefore, initial CIN activation regulation could be critical in Dox-induced actin cytoskeleton remodeling through RhoA/cofilin signaling.

The safety-evaluation of ancient wood structures has been executed with only visual inspection. The application of NDE(nondestructive evaluation) is required because the visual inspection has many restrictions. Among many NDE techniques, the stress wave technique was used in this research. This study focused on evaluating the extent of decay in members of ancient structures, using stress wave nondestructive technique. For application of stress wave technique to ancient structures, the threshold time which divides members into categories according to degree of decay should be determined in advance. Stress wave timer (Metriguard Model 239A) was used in this study, specimens used in this research were the members obtained from six ancient structures. All specimens were identified as Hard Pine(Pinus densiflora S. et Z. or Pinus thunbergii P.) by microscope. Each member was tested with stress wave passing radially through the pith. In this study, the stress wave time of $12{\mu}s$/cm could distinguish between sound and decayed specimens with accuracy of 77.5 percent. Also, decayed specimens could be separated into moderate and severe categories by stress wave time of $20{\mu}s$/cm. Among the three decay location groups (exterior, mixed, interior), the exterior group could be classified into sound, moderate and severe decay with the greatest accuracy. Stress wave transit time was not sensitive to small decay pockets located in interior of the member.

Nitric oxide (NO) is a versatile signaling molecule, which is not only involved in plant growth and development but also regulates biological processes in response to biotic and abiotic stresses. Exogenous application of NO regulates the endogenous level of nitric oxide in response to stress conditions and therefore, NO donors are frequently used for stress alleviation. However, NO has very short half-life along with high reactivity. Therefore, conventional NO donors are often disadvantageous due to the relative instability of NO. On the contrary, development of NO releasing nanoparticles is a potential technique for enhancing the availability of NO in plants. Therefore, our aim was to synthesize such potential NO releasing nanoparticles which may be useful for application in agriculture. We have prepared Chitosan encapsulated S-nitrosoglutathione nanoparticles (GSNONP) and tried it with different concentrations for basic research in Arabidopsis thaliana. Our results suggest that lower concentration of this nanoparticle is highly effective for better growth of plants whereas higher concentration produces toxicity that leads to plant death. We observed better growth of Arabidopsis thaliana at 1µM concentration of the GSNONP compared to free GSNO.

Purpose: The purpose of this study is to examine the mediating effect of acculturative stress on the impact of satisfaction with life and career identity on depression among the Vietnamese students enrolled in a language course in Korea. Methods: A questionnaire survey was conducted to get answers of 225 Vietnamese students enrolled in the language course in a college in Busan. Data were collected from November to December 2018. The Data were analyzed with descriptive statistics, Pearson's correlation coefficients and path analysis using SPSS/WIN 20.0 and Amos 18.0 program. Results: Acculturative stress was affected by satisfaction with life (β=-.43, p<.001) and career identity (β=-.45, p<.001). Furthermore, depression was affected by acculturative stress (β=.49, p<.001) and career identity (β=-.25, p<.001), but depression was not affected by the satisfaction with life (β=-.15, p=.029). The mediating effect of acculturative stress between two exogenous variables(satisfaction with life and career identity) and depression was proved. Conclusion: The result of this study suggests that it is necessary to develop an intervention program to reduce the acculturative stress and depression of Vietnamese students enrolled in the language course.
