입원을 경험하는 임상연구 환자가 증가하고, 이에 따라 이들을 돌보는 간호사들의 업무가 증가하고 있으나, 모호한 역할 경계로 혼란이 발생하고 있다. 본 연구는 임상연구업무 중 병동간호사의 참여가 가능한 직접실무 제공업무, 교육 및 상담업무, 옹호 및 조정업무에 대한 역할기대와 병동에서의 협력인식 및 협력 장애요인을 파악하기 위한 조사연구이다. 대상자는 병동 간호사 66명, 임상연구간호사 65명이었다. 자료수집은 SAS 9.3통계 프로그램을 이용하여 기술 통계, two-sample t-test, 𝑥² test 로 분석하였다. 연구결과, 임상연구 간호업무의 직접실무 제공영역, 교육 및 상담영역, 옹호 및 조정영역을 포함한 역할기대 점수는 병동간호사는 4.56±0.41점, 임상연구간호사는 3.83±0.60점으로 서로에 대한 역할기대 점수가 높게 나타났다. 통계적으로 병동간호사의 역할기대가 유의하게 (p<.001) 임상연구간호사보다 더 높게 나타났다. 두 군 간의 협력 인식은 5개 항목에서 유의한 차이가 나타났다. 협력장애요인으로는 업무과중과 임상연구에 대한 인식부재가 높은 순위로 나타났다. 높은 역할기대는 역할 갈등의 요소가 된다. 그러므로, 새로운 임상연구 간호업무에서의 병동간호사와 임상연구간호사의 역할 정립을 위하여 절차 마련과 효과적인 실무 관행의 정착, 공식적 시스템 운영이 필요할 것으로 사료된다. 두 군 간의 협력을 증진하기 위해서는 서로를 동반자로 생각하고 상대에 대한 전문성을 인정할 수 있는 상호 신뢰하고 협력하는 문화가 형성되어야 할 것으로 사료된다.

When measuring cerebrovascular with 3D rotational angiography, the accuracy was verified by comparing the actual size and measurement size, respectively. It is intended to help select therapeutic materials and instruments during cerebrovascular intervention by comparing the average error rates for measured values in the 3DRA and CTA methods by examining with protocols such as brain CTA, which are always performed in emergency situations. The mean error rate between the groups of measurers was ±3.655% for radiation technologist and ±3.331% for university students, and the mean error rate of the student group was within tolerance (±10%), and the independent sample T-test result t =0.879, p=0.394 (p>0.05) showed no statistically difference between the two. In addition, the average error rate measured by both groups by 3DRA was measured below ±5% within the tolerance error rate (±10%), and most of CTA was measured within the tolerance range (±10%), but showed an average error rate of up to 5.65%, and the independent sample T-test result was statistically more accurate than 3DRA. Both the 3DRA method and the brain CTA method for measuring cerebrovascular size could be accurately measured within tolerance, but it would be better to measure cerebrovascular blood vessels using a more accurate 3DRA method during cerebrovascular intervention.

The purpose of this study was to investigate the relationships between body-calthexis and clothing image preferences in male college students. The sample included 28 male college students and an instrument was developed based on the previous studies. The statistical analyses used for this study were factor analysis cluster analysis and t-test. The result of factor analysis showed that body-cathexis consisted of four areas of body parts: face/head upper body middle body and lower/total body. Clothing image preferences consisted of 'strong vs weak' 'soft vs hard' 'young vs mature' 'mannis vs feminine' and 'distinguished vs undistinguished' images. Cluster analysis revealed that male college students are segmented into two groups. and the two groups differed in regard to clothing image preferences such as 'strong vs weak' 'young vs mature' and 'mannish vs feminine' images. In addition the two consumer segments were different concerning body-cathexis for middle body and all body areas combined. The consumers who preferred feminine weak and mature clothing images were more satisfied with their middle area of the bodies and all body areas combined.

Purpose: We investigated the effects of music on pain, blood pressure, and pulse in patients with chronic back pain. We tried to find some change of satisfaction of treatment and a sense. Method: We recruited total 30 patients with chronic back pain, who had pain from lumbago for more than six months. Subjects received electrotherapy and electrotherapy with music one at a time during me test, and subjects received one in the morning and the other one in the afternoon. We compared the test results between the electrotherapy and electrotherapy with music. Visual Analogue Scale was used to check the effect on pain. Blood pressure and pulse were checked, too. The gathered informatio was analyzed by t-test, independent sample t-test, and chi-square test. Results: There was statistically not significant difference between electrotherapy and electrotherapy with the music in VAS(Visual Analogue Scale)(p>0.05). There were statistically some significant differences between two groups in systolic pressure, diastolic pressure, and the pulse(p<0.05). Subject group showed statistically higher scores of satisfaction(p<0.05). There was significant difference between two groups(p<0.05) in the tingling and vibration sense. Conclusion: we found that the lumbago patients who are treated by electrotherapy with the music did not have additional difference in relief of pain, but electrotherapy with music can get better effects on their blood pressure, the pulse, satisfaction, and tingling-vibration sense. This means that the patients receive their treatment comfortably with rest. Therefore, We consider that it is desirable to play music to lumbago patients to offer the better treatment service to the patients.

Purpose: This study was done to investigate factors influencing successful aging in middle-aged women. Methods: A convenience sample of 103 middle-aged women was selected from the community. Data were collected using a structured questionnaire and analyzed using descriptive statistics, two-sample t-test, one-way ANOVA, Kruskal Wallis test, Pearson correlations, Spearman correlations and multiple regression analysis with the SPSS/WIN 22.0 program. Results: Results of regression analysis showed that significant factors influencing successful aging were post-traumatic growth and social support. This regression model explained 48% of the variance in successful aging. Conclusion: Findings show that the concept 'post-traumatic growth' is an important factor influencing successful aging in middle-aged women. In addition, social support from friends/co-workers had greater influence on successful aging than social support from family. Thus, we need to consider the positive impact of post-traumatic growth and increase the chances of social participation in a successful aging program for middle-aged women.

PURPOSE. Considering the importance of metal-ceramic bond, the present study aimed to compare the bond strength of ceramics to cobalt-chrome (Co-Cr) alloys made by casting and selective laser melting (SLM). MATERIALS AND METHODS. In this in-vitro experimental study, two sample groups were prepared, with one group comprising of 10 Co-Cr metal frameworks fabricated by SLM method and the other of 10 Co-Cr metal frameworks fabricated by lost wax cast method with the dimensions of $0.5{\times}3{\times}25\;mm$ (following ISO standard 9693). Porcelain with the thickness of 1.1 mm was applied on a $3{\times}8-mm$ central rectangular area of each sample. Afterwards, bond strengths of the samples were assessed with a Universal Testing Machine. Statistical analysis was performed with Kolmogorov-Smirnov test and T-test. RESULTS. Bond strength in the conventionally cast group equaled $74.94{\times}16.06\;MPa$, while in SLM group, it equaled $69.02{\times}5.77\;MPa$. The difference was not statistically significant ($P{\leq}.05$). CONCLUSION. The results indicated that the bond strengths between ceramic and Co-Cr alloys made by casting and SLM methods were not statistically different.

Objective: To determine the changes in dental anxiety, state anxiety, and trait anxiety levels of patients and their parents after 3 months of active orthodontic treatment. Methods: We evaluated 120 patients and one parent of each patient. State Anxiety (STAI-S), Trait Anxiety (STAI-T), and Corah's Dental Anxiety Scale (DAS) were administered before orthodontic treatment (T1) and after 3 months of treatment (T2). Differences in scores between T1 and T2 were compared using paired-sample t-tests and the relationship between the scores of the DAS and the STAI were analyzed using a bivariate two-tailed Pearson correlation test. Results: Dental anxiety and state anxiety levels decreased among the patients after adjustment to orthodontic treatment (p < 0.001). However, 3 months of treatment was not sufficient to decrease the anxiety levels of parents (p > 0.05). Patient trait anxiety affected patient state anxiety and dental anxiety (p < 0.01). Additionally, a significant correlation was found between patient dental anxiety and parent dental anxiety (p < 0.05). Conclusions: Dental anxiety and state anxiety levels decrease after patients become familiar with their orthodontist and they became accustomed to orthodontic treatment. However, 3 months is not a sufficient length of time to decrease parental anxiety levels.

Bioequivalence of two clarithromycin tablets, the $Klaricid^{TM}$ (Ciba-Geigy Korea Ltd., Seoul, Korea) and the LG clarithromycin (LG Chemical Co., Ltd., Seoul, Korea), was evaluated according to the Korean Guidelines for Bioequivalence Test (KGBT 1998). Sixteen normal male volunteers $(20{\sim}26\;years\;old)$ were randomly divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After one tablet containing 250 mg of clarithromycin was orally administered, blood sample was taken at predetennined time intervals, and the concentrations of clarithromycin in serum were detennined using HPLC method with electrochemical detector. The pharmacokinetic parameters $(AUC_t,\;C_{max}\;and\; T_{max})$ were calculated and ANOVA was utilized for the statistical analysis of parameters. The results showed that the differences in $AUC_t$, $C_{max}$, and $T_{max}$ between two tablets based on $Klaricid^{TM}$ tablet were 4.06%,2.67% and -9.70%, respectively. The powers $(1-{\beta})$ for $AUC_t$, $C_{max}$ and $T_{max}$ were 83.53%, 92.34% and 96.64%, respectively. Detectable differences $({\Delta})$ and 90 % confidence intervals $(a=0.05) $were all less than ${\pm}20%$. All the parameters above met the criteria of KGBT 1998, indicating that LG clarithromycin tablet is bioequivalent to $Klaricid^{TM}$ tablet.
