This cross-sectional descriptive study investigated the influence of romantic relationships' characteristics, self-esteem and sexual autonomy on limerence in dating relationships among female college students who had or were currently engaged in a dating relationship. The data was collected through self-reported structured questionnaires from 167 female Korean college students using convenient sampling methods from November 25, 2012 to December 20, 2012. The data was analyzed using t-tests, one-way analyses of variance, Scheffe's test, Pearson's correlation coefficients, and multiple linear regression analysis with the IBM SPSS 23.0 program. The results showed that a significant difference was found in limerence according to the frequency of experiencing romantic breakup (F=4.16, p=.003), and limerence in dating relationships was negatively correlated with self-esteem (r=-.31, p<.001) and sexual autonomy (r=-.21, p=.006). Self-esteem and the frequency of romantic breakups explained 20% of limerence in dating relationships among the participants (F=8.03, p<.001). Therefore, as a strategy to solve the problems related to limerence during the period of dating, cognitive and educational interventions are needed to strengthen the self-esteem and sexual autonomy of college students who have had a high number of separations. In addition, early screening of college students with risk factors for limerence and providing problem-solving based counseling will help improve their psychological health.

With the emergence of new infectious diseases and changes in the educational environment, the health problems of school-age students are increasing. Accordingly, the role of school health teachers is expanding and becoming more important. The study was to examine the effect of calling on school organizational commitment of school health nurses. Samples were a total of 143 school health nurses working in elementary, middle, and high schools, Gyeonggi-do, South Korea who understood the purpose of this study and voluntarily participated in the study. Measures were Calling and Vocation Questionnaire-Korea (CVQ-K) and organization commitmen questionnaire. Data were analyzed using SPSS/WIN 23.0 program. The analyses showed that the prediction model for school organizational commitment of school health nurses was significant (F=16.142, p<.001). The value of the adjusted R² was 0.307, which corresponds to the explanatory power of 30.7%. The factor that was found to have the most influence on school organizational commitment of school health nurses was purpose/meaning (β=.28, p=.011), followed by number of classes (β=-.20, p=.006). In order to improve the school organizational commitment of school health nurses, the purpose/meaning and the number of classes should be considered.

This study was conducted to identify pain intensity and factors affecting pain intensity in patients with advanced cancer. Data were collected between June 1 and September 30, 2016 using a questionnaire. The sample size was 221 patients with advanced cancer who were admitted to the oncology department or who visited the outpatient of the general hospital. Data were evaluated by descriptive and Pearson's correlation analyses, one way ANOVA, t-tests and stepwise multiple regression analysis. The mean scores of pain intensity of cancer patients were 4.23 (${\pm}1.68$) based on the average daily pain intensity. Factors influencing pain intensity were illness perception (${\beta}=.27$, p<.001), pain opioid analgesics beliefs (${\beta}=.24$, p<.001), education (middle school, ${\beta}=.24$, p=.001), economic status (${\geq_-}400$, ${\beta}=.20$, p=.001), gender (female, ${\beta}=.14$, p=.017), pain management education (${\beta}=-.14$ p=.020) and diagnosis (Pancreatic Ca, ${\beta}=.14$, p=.020). It explained 28%. Overall, the results of this study revealed that illness perception and pain opioid analgesics beliefs were important factors influencing pain intensity, but that the most important influencing factor was illness perception. Accordingly, it is necessary to develop pain management strategies that include not only pain management knowledge and pain opioid analgesics beliefs, but also illness perception.

Purpose: This study was conducted to examine prerequisite-program performance of the hospital foodservice operation and develop measures for improvement of prerequisite-program performance. Methods: Data were collected through surveys administered to 168 hospital dieticians in the Seoul, Incheon, Gyeonggi-do, Daegu, and North Gyeongsang areas. Out of total questionnaires, 65 questionnaires were usable and the response rate was 38.7%. Statistical analyses were performed using the SPSS program (ver 20.0) for ${\chi}^2-test$ and one-way ANOVA. Results: According to the result of the prerequisite-program evaluation, the percentage of 'appropriate', 'needs to be improved', and 'inappropriate' was 44.6%, 47.7%, and 7.7%, respectively. The score for the 'inappropriate' group was significantly lower than that of the 'appropriate' group or 'needs to be improved' group on the food safety management (p < 0.001), preparation facility management (p < 0.001), water management (p < 0.001), and storage transportation management (p < 0.05) parts. Holding rate of foodservice facility and equipments in the 'appropriate' group were significantly higher than in the others on convection oven (p < 0.01), air conditioner (p < 0.01), three-compartment sink (p < 0.01), hot-holding equipment (p < 0.01), cold-holding equipment (p < 0.05), exclusive thawing refrigerator (p < 0.05), and sterilizer for sanitary shoes (p < 0.05) items. Conclusion: To improve the quality of hospital foodservice, foodservice managers and HACCP specialists should develop and implement a prerequisite-program and a HACCP plan considering the characteristics of the hospital foodservice operation.

Though it has been known that self-efficacy is a predictor to the successful L2 learning, the majority of studies on self-efficacy cases were targeted at secondary school students. This paper aims to explore the effects of the intermediate college students' essay writing experiences on their English self-efficiency. For this purpose, pre and post course surveys were conducted on a hundred or so freshmen who took intermediate college English classes which focused on improving English reading and writing skills. Interviews with teachers were also conducted in order to find out whether the differences of their teaching styles had any meaningful impact on their students' self-efficacy. Paired t-test was run on the responses of the post-questionnaire to identify any differences in the self-efficacies of the students before and after taking the classes, and the one-way ANOVA was conducted to find out whether the different instruction types had any significant impact on the differences. The results of the both analyses confirmed the differences of self-efficacies by the two predictors at a statistically significant level. Based on the findings of this paper, various types of writing assignments and efficient procedures of teachers' feedback need to be developed further in order to design and run an effective college English course which can contribute to enhancing self-efficacy of students.

This study was designed to identify the knowledge, perception, self-efficacy, and performance on radiation protection among perioperative workers in terms of radiation protection. The factors affecting the performance of radiation protection were identified, and provide basic data for the development of an effective radiation protection education program. The sample was comprised of 166 perioperative workers who agreed to participate in this descriptive study. Data analysis was performed using the t-test, analysis of variance, Pearson's correlation, and multiple regression analyses on the SPSS 23.0 Program. The average time of radiation exposure was 3-4hoursThe radiation protection education experience was 11.4%. The average score of radiation protection knowledge was $8.61{\pm}2.51$; the perception was $4.59{\pm}0.64$; and the performance was $2.99{\pm}0.90$ There was a significant difference in the degree of radiation defense knowledge and performance among the general characteristics (p <001). Knowledge of radiation protection was correlated with the perception. The performance of radiation protection was correlated with the knowledge. The knowledge and perception of radiation protection behaviors should be increased to improve radiation protection performance. Therefore, it is important to promote the performance of radiation protection behaviors by improving the perioperative workers' knowledge of radiation protection through reinforcing radiation-related education.

PURPOSE. Heat of composite polymerization (HP) indicates setting efficacy and temperature increase of composite in clinical procedures. The purpose of this in vitro experimental study was to evaluate the effects of 5 temperatures on HP of two new composites. MATERIALS AND METHODS. From each material (Core Max II [CM] and King Dental [KD]), 5 groups of 5 specimens each were prepared and their total HPs (J/gr) were measured and recorded, at one of the constant temperatures $0^{\circ}C$, $15^{\circ}C$, $23^{\circ}C$, $37^{\circ}C$ and $60^{\circ}C$ ($2{\times}5{\times}5$ specimens) using a differential scanning calorimetry (DSC) analyzer. The data were analyzed using a two-way ANOVA, a Tukey's test, an independent-samples ttest, and a linear regression analysis (${\alpha}=0.05$). RESULTS. No polymerization reactions occurred at $0^{\circ}C$; then this temperature was excluded from statistical analyses. The mean HP of the remaining 20 KD specimens was $20.5{\pm}14.9$ J/gr, while it was $40.7{\pm}12.9$ J/gr for CM. The independent-samples t-test showed that there were significant differences between the HP of the two materials at the temperatures $15^{\circ}C$ (P=.0001), $23^{\circ}C$ (P=.0163), $37^{\circ}C$ (P=.0039), and $60^{\circ}C$ (P=.0106). Linear regression analysis showed statistically significant correlations between environment temperatures and HP of CM ($R^2=0.777$). CONCLUSION. Using CM is advantageous over conventional composite because of its better polymerization capacity. However due to its high HP, further studies should assess its temperature increase in vivo. Preheating KD is recommended. Refrigerating composites can negatively affect their polymerization potential.

This study was carried out to investigate the levels of awareness of fermented vegetable beverages according to consumers' gender. The data were obtained through questionnaires completed randomly by 441 respondents and analyzed using the SPSS, t-tests, ANOVA, X-square tests, multiple regression, and logistic regression analyses. Among 441 respondents, 32.9% of male and 30.2% of female ever consumed fermented vegetable beverages. This beverage were consumed as an alternative for water in males (6.3%) and in females (7.9%) which was the most common reason for consumption. As for the most common reason for non-consumption, males (5.9%) and females (6.6%) responded that they did not consume fermented vegetable beverages because people around them have never consumed fermented vegetable beverages. The awareness that fermented vegetable beverages help reduce hunger was higher in females (3.2%) than and in males (2.9%). These results revealed that the awareness of fermented vegetable beverages as hunger alleviators was more prevalent in females than in males which can be used as preliminary data for research on the development of fermented vegetable beverages.

Most patients having leukemia suffer severely from emotional turmoil due to the generalized perception that cancer will be fatal. The conventional chemotherapy results in side effects such as severe bone marrow depression which interfere with self-care management, vital for improvement in their condition. Bandura's theory of the self-efficacy suggests that self- efficacy can be enforced by performance attainments, vicarious experiences, verbal per-suasion and the release of emotional arousal. Self-efficacy can be enforced by a program of vicarious experiences and verbal persuasion, while the emotional arousal can be relieved through a hope promotion program, If once self-efficacy increases, the patient's self-care behaviors and the quality of life will also increase. The purpose of this study was to empirically test the effects of a program, to promote self-efficacy and hope, on self-care behaviors and quality of life in patients having leukemia. In this study, three types of approaches to enhance self-efficacy and hope were used : 1) a 20-minute long slide /tape for vacarious experiences : 2) a 10-minute long telephone call coaching for verbal persuasion ; and 3) two booklets for information about the symptoms of leukemia and treatment modalities and hope promotion. Thirty one patients were recruited in the experimental group and 29 in the control group with a nonequivalent pretest-posttest design. The subjects were patients with leukemia undergoing chemotherapy. Sherer and Maddux's self-efficacy scale, Nowotny's hope scale, and Padilla's quality of life scale were employed with some modifications. A self-care behavior scale was developed by the researchers. Statistical analyses including paired t-test, Chi-square, ANCOVA and ANOVA, were used. The results are as follows : The levels of self-efficacy, self-care behavior and quality of life were higher in the experimental group than in the control group after four weeks of intervention(F=28.71, P=.0001 ; F=63.35, P=.0001 F=16.57, P=.0001). After ten weeks of intervention, all of the dependent variables(self-efficacy, self-care behavior, hope & quality of life) in the experimental group were higher than in the control group (F=74.12, P=.0001 ; F=108.34, P=.0001 ; F=13,11, P=.001 : F=43.52, P=.0001). In conclusion, self-care behavior and quality of life increased mainly through an increase in self-efficacy, while increases in hope took more time and effort.

The purpose of this study was to evaluate the micro-tensile bond strength (${\mu}TBS$) of four luting resin to regional dentin of human primary teeth. Dentin from non-carious primary molars were prepared from different regions (s, superficial dentin; d, deep dentin; c, cervical dentin), and divided into groups based on anatomical locations and types of luting resins (Scotchbond Multi-purpose : SB ; One-Step : OS ; AdheSE Bond : ASE ; G-Bond : GB) : SB-s, SB-d, SB-c; OS-s, OS-d, OS-c; ASE-s, ASE-d, ASE-c ; GB-s, GB-d, GB-c. Luting resins were used according to the manufacturers' instructions, to bond $Light-Core^{TM}$ Core Build-Up Composite) to the exposed dentin specimens in the light-curing mode. After storage for 1 day, ${\mu}TBS$ was tested at a cross-head speed of 1 mm/min. Data were analyzed with T-test and two-way ANOVA. The bonding interface and fractography analyses were performed with SEM. The results were as follows : 1. ${\mu}TBS$ to superficial dentin was significantly higher than to deep dentin for SB(p<0.05). But there were no significant differences in regional ${\mu}TBS$ among OS, ASE, GB(p>0.05). 2. There were no significant differences in ${\mu}TBS$ to superficial dentin among each groups. But, in deep dentin, ${\mu}TBS$ of SB-d was significantly lower than those of OS-d, ASE-d, and GB-d(p<0.05). ${\mu}TBS$ of OS-d was significantly higher than those of GB-d(p<0.05), but there were no significant differences in ${\mu}TBS$ of ASEd. There were no significant differences among ${\mu}TBS$ of ASE-d, OS-d, and GB-d.
