This study was conducted to identify the characteristics of pain, self-esteem, perceived health status, and self-efficacy and its influencing factors in patients with chronic arthritis. The data were obtained from 104 patients with chronic arthritis registered in one university hospital in Seoul, from May to August, 2000. For analysing the data, SAS program was used for t-test, ANOVA, Scheffe test, Pearson correlation, and stepwise multiple regression. The results were as follows: 1. The variables which showed significant difference with pain were sex, number of painful joints. 2. The variables which showed significant difference with perceived health status were age, diagnosis. number of painful joints. 3. The variables which showed significant difference with self-efficacy were duration of disease, number of painful joints. quality of sleeping. 4. Moderate negative correlation were observed between pain and perceived health status, self-efficacy, and low positive correlation was observed between self-esteem and perceived health status. Also self-esteem revealed moderate positive correlation with self-efficacy, and moderate positive correlation was observed perceived health status and self-efficacy. 5. The predictors to explain self-efficacy were number of painful joints, self-esteem, duration of disease, duration of exercise and pain. These predictors explained $36.05\%$ of variance of self-efficacy. In conclusion, the nursing intervention to improve self-efficacy for chronic arthritis patients focused not only physiological symptoms such as pain. but also psychosocial factors such as self-esteem.

This study was conducted to investigate the factors affecting the social anxiety in nursing students. A total of 227 nursing students participated in the study. Data were analyzed by frequencies, t-test, ANOVA, Pearson correlation coefficient, and multiple stepwise regression with SPSS WIN 18.0. The mean scores for problem solving ability and social anxiety were at the intermediate level. Problem solving ability negatively correlated with social anxiety. The significant predictors of social anxiety included cognitive reaction within the seven problem solving ability subscales and perceived interpersonal relationship. The regression model explained 22.6% of social anxiety. As a result, to decrease social anxiety in nursing students, nursing educators should develop educational intervention programs to change cognitive distortions presented in unfamiliar social situations and improve interpersonal relationships ability.

While online shopping has been increased expeditiously, a significant portion of purchasing intention has not been converted into actual purchasing behavior without delay in online space. This study investigates the factors causing a delay in online purchasing decision even after purchasing intention has been formed. It identifies the uncertainty variables (information, psychological, and preference uncertainties) related to consumer needs and the situational variables (time pressure and past purchase experience) surrounding the purchasing transaction. Furthermore, the need for cognitive closure is proposed to moderate the relationships between uncertainty/situational variables and the purchasing behavior. The results show that the uncertainties and situational factors significantly influence purchasing delay. Also, the need for cognitive closure indeed works as a moderator between the uncertainty variables and the purchasing behavior. Practical and academic implications of these findings are also discussed.

We observed 117 orthognathic surgery cases with dentofacial deformity for 8 years from Jan. 1986 to Dec. 1993. The ratio of male female was 1 : 1.4 and the mean age was 23.0 years ranged from 16 to 35 years. The most dominant group was related to mandibular prognathism (75.0%). Surgery method were divided into 88 cases of mandible surgery, 6 cases of maxilla surgery and 23 cases of two jaw surgery. Sagittal split osteotomy were performed on 84 cases (71.8%). Rigid fixation was increased after 1989 and total percent of rigid fixation was 66%. We used autotransfusion method from 1992 to all orthognathic surgery patient. Lower lip numbness caused by Inferior alveolar nerve injury is the most common problem after operation, and it was 63 cases (53.8%) of total operation cases. In our clinic, we performed 5 cases of re-operation because of segment malalignment, condylar sag, and fixation instability.

Purpose: This study was designed to assess the types of nursing organizational culture, and degree of self-leadership and burnout as perceived by perioperative nurses, and to identify correlations between these variables. Methods: Participants were 155 nurses from 3 tertiary hospitals in Seoul and data were analyzed using descriptive statistics, ANOVA, Scheffe, and Pearson correlation coefficient. Results: In the types of nursing organizational culture, the mean score for hierarchy-oriented culture was 3.57, and for self-leadership, 3.61 and for burnout, 2.87. In the relationship between the types of nursing organizational culture, self-leadership and burnout, relation-oriented culture (r=.24, p<.01), innovation-oriented culture (r=.23, p<.01) and task-oriented culture (r=.22, p<.01) had a slight positive correlation with self-leadership in that order. The innovation-oriented culture (r=-.29, p<.01) and relation-oriented culture (r=-.42, p<.01) among the types of nursing organizational culture showed a negative correlation with burnout while the hierarchy-oriented culture (r=.28, p<.01) showed a positive correlation with burnout. Self-leadership showed a negative correlation with burnout (r=-.42, p<.01). Conclusion: The results show that nurses in operating rooms have a high awareness of hierarchy-oriented culture that affects burnout in a negative way while having a low awareness of relation-oriented culture that has a positive influence on burnout.

When a human being grew older, followed by visually and perceptually impaired, and dementia, it jeopardizes safety and life unless supportive design is secured for a living environment. This supportive space is based on universal design concept which offers safe-oriented, and simple use by incorporating gender and physical/mental limitation. The study of purppose was to examine the appropriateness of barrier-free standard for seniors' living in apartment through IPA. Chi-square analysis found that satisfaction with BF space is lowered as aging is continued and for female group. Regression analysis indicated that sink was the prime predictor in satisfaction, and stair/elevator was the most important variable. IPA concluded that sink, bath, shower/locker and alert/egress were prime BF indexes to be improved among 14 elements, implying careful design in sanitation area for seniors.

Currently, in order to meet the reinforced emissions regulations for harmful exhaust gas including carbon dioxide ($CO_2$) as a greenhouse gas, technologies for reducing $CO_2$ emission and fuel consumption are being developed. Gasoline direct injection (GDI) systems have the advantage of improved fuel economy and higher power output than port fuel injection gasoline engine systems. The aim of this study is to examine the performance and emission characteristics of a lean burn GDI engine equipped with spray-guided-type combustion system. Stable lean combustion was achieved with a late fuel injection strategy under a constant operating condition. Further improvement in specific fuel consumption is possible with the introduction of multiple fuel injection strategies, which also increases hydrocarbon (HC) and nitrogen oxide ($NO_x$) emissions and decreases carbon monoxide (CO) emission.

The present study tried to provide useful data for the acoustic design of sound amplification system with measuring and analyzing subjective preference and intelligibility by varying the number of speakers and their directivity. The results suggest that the room absorption plays a key role in subjective responses of listeners and the large sound absorption of ceiling contributes to the increase of intelligibility. Also, larger number of speakers with narrow directivity improves perceived intelligibility when speakers were installed at the lower height. However, the highest degree of intelligibility and preference were obtained when speakers were installed close enough to the sound absorptive ceiling. The highest intelligibility and preference were observed when 8 to 10 speakers with the directivity of 60 degree were used.
