The purpose of this study was to investigate what effect providing the hospice care team with hospice education programs had on the death orientation. The subjects of study were 28 volunteers. 14 nurses. 30 clergies who registered on hospice education programs from Aug. 6th. 1996 to May 20th. 1997. The data were analysed by descriptive analysis. ANOVA. Duncan test. paired t-test. The results of the study can be summarized as follows ; 1. The degrees of death orientation were 85.70 in volunteers group. 84.31 in nurses group. and 73.00 in clergies group. So. clergies group has more positive death orientation than others(F=6.33. p=. 000). The degree of death orientation showed significant differences between age groups(F=5.78. p =.002). and religiosity(t=3.92. p=.000). There were no significant differences between the degree of death orientation and the others general characteristics of subjects. 2. The mean of death orientation was 80.04 before hospice education programs. but was 75.56 after hospice education programs(t= 3.92. p= .000). In conclusion. the subjects who received the hospice education programs showed the positive change in the degree of the death orientation. Therefore. it has been judged that education programs has been prerequisite in positive death orientation for hospice care. Furthermore. all of the hospice care members those who complete the hospice education program. will be performed efficient hospice care intervention for dying patients and their families.

The objective of this study was to investigate the problem behavior and its convergent factors in out-of-school adolescents, with a focus on gender differences. This study was a secondary data analysis study using out-of-school adolescents research data at Busan women and family development institute. The study was conducted in a total of 499 out-of-school adolescents (337 males, 162 females). The type of the 8 problem behaviors (run away from home, drop out, prostitution, violence, internet game addiction, theft, drug addiction, and smoking) were identified. The collected data were analyzed with multiple logistic regression. Among the problem behaviors of the participants, internet game addiction and theft were more significantly high in male out-of-school adolescents than female out-of-school adolescents. In internet game addiction, male out-of-school adolescents were 1.90 times higher than female out-of-school adolescents (p=.008, 95% CI=1.18-3.06). In theft, male out-of-school adolescents were 1.92 times higher than female out-of-school adolescents (p=.006, 95% CI=1.21-3.03). When the social measures were provided for those adolescents, a distinguished approach is required depending on the problem behavior and gender.

This describes the level of knowledge and attitudes about HIV and their related factors among Cambodian adolescents. A cross-sectional design was used to examine the knowledge and attitude of 463 Cambodian high school students using HIV-KQ-18 (HIV-Knowledge Questionnaire-18) and HIV/AIDS Behavior Surveillance Survey Index (measuring attitude about HIV). The majority of the adolescents had a relatively low level of overall HIV knowledge (6.70 ± 3.66 (range: 0-16)) and held a very negative attitude (1.92 ± 0.87 points (range: 0-4)) toward the disease. Using multiple regression analysis, being male (β = 0.28, p < 0.001) and using YouTube as a social network service (β = 0.33, p = 0.035) were found to be independent factors associated with higher level of HIV knowledge. Study findings suggest the importance of informing policymakers and school nurses about the need to develop a and require a culturally sensitive specific health education program on HIV for Cambodian adolescents.

Purpose: This study was done to examine predictive validity of Critical Care Non-verbal Pain Scale (CNPS) and develop criteria for pain assessment using CNPS with critically ill patients who have communication problems. Methods: Data were collected from intensive care units at three major general hospitals in Seoul and Kyunggi province. During each observation, a nurse assessed pain severity using CNPS ratings (range 0-9) at four treatment stages: at rest, during central catheter dressing change (nonpainful procedure), position change and suctioning (routine painful procedures). Patients also assessed their pain using a self-report 4-point VRS-4. Results: There were significant differences between the four treatment stages except between "at rest" and "nonpainful procedure". Strong correlations were found between CNPS and VRS-4 for "at rest" (r=.552, p<.001), central catheter dressing change (r=.505, p<.001), position change (r=.709, p<.001), and suctioning (r=.662, p<.001). ROC curve analysis of CNPS based on 3 point on VRS-4 showed the cutoff point was 3 for CNPS, the starting point for pain management with 73% sensitivity, 92.2% specificity, 73% positive predictive value, and 92.8% negative predictive value. Conclusion: Results indicate that CNPS is a valid tool for measuring pain in critically ill patients with communication problems and 3 point should be the standardized pain treatment point.

To study vegetation structure and distance between trees of Pinus densiflora forest in Chayang-chon area, Soraksan National Park, thirty-nine plots(10m$\times$10m) were established. They were classified into two communities by TWINSPAN and DCA technique. In the Community I, P. densiflora(DBH 35~75cm, height 9~16m, age 60~80) dominated in canopy and were predicted to be changed by deciduous broad-leaved trees also. In the Community II, P. densiflora(DBH 9~26.5cm, height 9~16m, age 30~50m) dominated in canopy. It seemed that the community II would maintain P. densiflora community for a long time since P. densiflora dominated in both canopy and understory. Shonnon's diversity index was higher in the community II(1.4247) than in the community I(1.2978). The distantes between canopy trees were 4.92$\pm $2.14m in the community I and 2.41$\pm $0.97m in the community II. The regression between DBH in canpy and ecological distance was Y(Distance) = 0.06355$\times $(DBH)+1.51613.

Purpose: The aim of this study was to investigate the perceptions of nurses regarding their roles in social welfare facilities, including role expectation, role performance, and role conflict and its influencing factors. Methods: Data were collected by administering a structured questionnaire to 92 nurses working in 5 types of social welfare facilities. Descriptive statistics, paired t test, Pearson correlation coefficient, and multiple linear regression analyses were performed using the SPSS Win 18.0 program. Results: The mean score of role expectation ($4.44{\pm}0.41$) was significantly higher(t =17.50, p<.001) than that of role performance ($3.46{\pm}0.005$). The biggest mean difference between role expectation and role performance was found in "research activities" ($2.92{\pm}0.81$). The mean score of role conflict was $2.89{\pm}0.66$, with the highest mean score found in "conflict caused when one nurse takes up two or more roles" ($3.31{\pm}0.69$). The influencing factors on role conflict were the difference between role expectation and role performance(${\beta}=.45$, p<.001), and facility size (${\beta}=-.37$, p<.001), which accounts for 51.5% incidence of role conflict controlling nurses' age, career, position, and working periods in social welfare facilities (F=17.13, p<.001). Conclusion: The nurses working in the social welfare facilities perceived some restrictions on their role performance compared with their role expectation, this difference being a major factor influencing their role conflict. Therefore, future studies need to investigate interventions to minimize this effect.
