Purpose : The purpose of this study was to identify the extent to which nurses' death perceptions, death anxiety, and stress associated with terminal care affects their attitudes toward terminal care. Method : A total of 214 nurses were asked questions about characteristics, death perceptions, death anxiety, stress associated with end-of-life care, and terminal care attitudes, using structured questionnaires. The data were analyzed using descriptive analysis, t-test, ANOVA, Scheffé's test, Pearson's correlation coefficients, and stepwise multiple regression. Results : Factors influencing terminal care attitudes in participants were positive meaning associated with death, respect for life, final education, end-of-life nursing education experiences, stress associated with end-of-life care, death anxiety, and position. These factors explained 38.7% of variance in participants' terminal care attitudes (F=20.18, p<.001). Conclusion : In order for nurses to have a positive attitude toward terminal care, it is necessary to raise positive awareness about death and respect for life, and it is necessary to develop various educational programs and strengthen their capacity through continuous education.

Purpose: This study aims to investigate the factors affecting fatigue of care helpers in long-term care facilities. Methods: The subjects consisted of 131 care helpers at six long-term care facilities in Chungcheongnam-do. A survey was conducted between July and September 2019 to collect data, which were analyzed using t-test, ANOVA, Pearson's correlation coefficients, and multiple regression analysis.Results: An increase in fatigue of care helpers owing to taking care of over 10 patients a day, increase in emotional labor and sleep disturbance, and a decrease in economic status was observed. Their fatigue decreased when there was an increase in their subjective health status and job satisfaction. Work-related stress (β=.37, p<.001), emotional labor (β=.21, p=.014), and sleep disturbance (β=.18, p=.026) significantly predicted fatigue. These factors explained 37% of the total variance in fatigue (F=10.48, p<.001).Conclusion: In addition to improving the work environment, interventions that alleviate emotional labor and improve sleep quality, are needed to lower the fatigue of care helpers.

Induction of non-diapause eggs and manifestation of quantitative characters were studied in different seasons by low temperature incubation of eggs of a low yielding diapause with coloured cocoons silkworm breed, RDI of Bombyx mori. Hundred percent of nandiapause eggs were induced when the egg incubation was carried out at 15$^{\circ}C$ followed by incubation initially at $25^{\circ}C$ and then at $15^{\circ}C$. The diapause-nondia-pause relation was found to be reversible. Analysis of variance study demonstrated significant variation in all the quantitative characters whereas significant variation due to different incubation treatments was observed for larval span, fifth instar larval span, cocoon yield/10,000 larvae by weight, cocoon weight, cocoon shell weight, and cocoon shell ratio. study on hybrid vigour skewed significant heterosis over mid parent value for four economic characters viz., cocoon weight, cocoon shell weight, cocoon shell ratio and filament length in a Fl hybrid between RD1 with diapause eggs and Japanese type bivoltine $NB_{4} D_{2}$.

The purpose of this study was to examine the acute effects of nerve mobilization, static stretching, and hold-relax on the flexibility of hamstring muscles and their surface electromyographic (EMG) responses to passive stretches in poststroke hemiparesis. This study was a randomized cross-over trial. Fourteen subjects received three treatment sessions in random order with each consisting of ten repetitions. The treatment sessions included nerve mobilization, static stretching, and hold-relax. The treatment sessions were held at least 24 hours apart to minimize any carryover effect. The outcome was measured by the distance between the greater trochanter and lateral malleolus and hamstring EMG activity during passive knee extension stretching. Repeated-measures analysis of variance showed significant changes in hamstring flexibility and EMG activity in main effect of time pre, post and followup (p<.05). However, no significant differences occurred among the three stretching techniques. No technique was consistently found to be superior. The three stretching techniques in this study make it difficult to determine the most effective technique. Therefore, clinicians use nerve mobilization of effective stretching techniques with other stretching techniques.

Purpose: This study was conducted to examine the relationships of depression symptom, self-esteem, and stress with health-related quality of life(HRQOL) in patients with hypertension registered to a community health center. Methods: This study was a correlational survey using a convenience sampling. A total of 110 patients diagnosed with hypertension were recruited from a health center in Gyeonggi-do. The questionnaires used were the Cardiovascular Disease Specific-HRQOL questionnaire, Center for Epidemiologic Studies Depression, Rosenberg Self-Esteem Scale, and Perceived Stress Scale. The acquired data were analyzed using IBM SPSS version 22.0. Multiple linear regression analysis was performed. Results: Moderate depression symptom(${\beta}=-.368$, p<.001), severe depression symptom (${\beta}=-.450$, p<.001), stress(${\beta}=-.339$, p=.001), and gender(${\beta}=-.148$, p=.049) were significant predictors for the HRQOL. Multiple linear regression showed that 51.8% ($R^2=.518$) of the variance in the HRQOL was explained. Conclusion: Based on these results, development of an intervention or education program, to decrease depression symptoms and stress is recommended. This may improve the HRQOL in patients with hypertension registered to a community health center.

Genetic and pharmacological studies in mice have demonstrated a complementary role for the melanocortin 4 receptor (MC4R) in the control of food intake, energy balance and body weight. This study was designed to investigate the associations of a MC4R gene polymorphism on chicken growth and body composition traits in broiler lines divergently selected for abdominal fat. A SNP (G54C) was found in CDS region of chicken MC4R gene. The analysis of the least squares and variance revealed a significant association between the G54C SNP and BW, CW and SL at 7 wk of age, and there were significant differences in different genotypes (p<0.05). The results from protein secondary structure prediction and tertiary structure prediction showed that it appeared a helix in $13^{th}$ amino acid and two strands at $14^{th}$ and $15^{th}$ amino acid in mutant protein, respectively. It maybe induce the change of the activity or function of MC4R gene in poultry.

Purpose: This study was aimed to identify the influencing factors on the quality of life among breast cancer survivors. Methods: The subjects were 159 female patients who visited out-patient department (OPD) after the mass removal surgery for breast cancer and had completed adjuvant treatments such as chemotherapy, radiation therapy at a university hospital and a general hospital. Data collection was conducted using the Ferrell QOL scale, the Mishel uncertainty scale, the Fitts & Osgoods body image scale revised by Jeon & Kim. the Rosenberg self-esteem scale, and the Kang family support scale. Results: The level of QOL in the participants was in the middle. There were a significant correlation between QOL, uncertainty, self-esteem, and family support. There were significant differences in QOL with the perceived health condition and the best support person. In a regression analysis, the most powerful predictor of QOL was body image (21.7%). Altogether uncertainty and perceived health condition explained 28.6% of the variance of QOL of the participants. Conclusion: Body image, uncertainty, and perceived health condition were important predictors of QOL. These results demonstrated the need for developing interventions to improve QOL of breast cancer survivors.

Purpose: This study was conducted to investigate the effects of blood flow restriction and different support surfaces for bridge exercises on the thickness of the transverse abdominis and multifidus, which are trunk-stabilizing muscles. Methods: The study's subjects were 45 adults who were divided into three groups that performed bridge exercises over a six-week period on their respective support surfaces after blood flow restriction. Changes in the thickness of the subjects' transverse abdominis and multifidus muscles were measured using ultrasonography before the experiment, then three and six weeks after the experiment. The changes in each variable over time were analyzed using a repeated-measures analysis of variance (ANOVA). Results: The transverse abdominis showed significant differences in muscle thickness with regard to time and the interaction between time and each group (p<0.05), but no significant differences with regard to changes among groups (p>0.05). The multifidus showed significant differences in muscle thickness with regard to time, the interaction between time and each group, and changes between groups (p<0.05). Conclusion: Blood flow restriction and different support surfaces for bridge exercises led to significant differences in the thickness of the transverse abdominis and multifidus. This study's results may be used as the basis for future studies and for rehabilitation in clinical practice.

Tribological properties of high temperature fade were investigated by changing relative amounts of ingredients in the brake friction material. Based on a simple experimental formulation containing 10 ingredients, friction materials were tested using a pad-on-disk type friction tester. Twenty-five friction material specimens with different relative amounts of the ingredients were manufactured according to the constrained mixture design .The difference ($\Delta$${\mu}$=${\mu}$$\sub$max/. -${\mu}$$\sub$min/. ) of friction coefficients was measured to represent the high temperature fade. Results from elevated temperature tests showed that five ingredients including cashew, graphite, Sb$_2$S$_3$, ZrSiO$_4$, and Cu fibers played important roles on $\Delta$${\mu}$. In order to find relative importance on fade phenomena among these ingredients, ANOVA(analysis of variance) was performed in this investigation. Thirty-two friction material specimens by changing ${\pm}$50vol.％ of these five ingredients were tested to examine the relative importance. Results showed that cashew, graphite '||'&'||' Sb$_2$S$_3$, and cashew '||'&'||' graphite aggravated the fade behavior and Cu fibers improved on fade resistance.
