본 연구는 간호학생이 첫 임상실습을 경험한 후 달라진 전문직관, 직무만족, 역할갈등의 변화를 파악하며 간호학생의 임상 실습교육 향상을 위한 기초자료를 제공하자고 시도되었다. 첫 임상실습 후 간호학생의 전무직관(t=-2.184, p=.031), 직무만족(t=-2.068, p>.001)은 상승하였다. 그러나 부정적 요소인 역할갈등(t=-3.729, p>.001) 역시 상승하였다. 즉, 간호학생은 첫 임상실습을 통해 예비간호전문인으로서 바른 전문직관을 세우고 자신의 업무에 대해 만족감을 느꼈다. 그러나 간호학생은 첫 임상실습을 통해 임상에서의 현실적인 간호사 역할을 경험한 후, 오히려 심각하게 자신의 미래 직업에 대한 고민을 하는 것을 알 수 있었다. 특히 역할갈등의 하부영역 중 개인 내 갈등(t=-3.729, p>.001), 역할모호성(t=-5.720, p>.001)에서 심각한 갈등을 느끼므로, 간호학생을 위한 업무기준과 직준표준안 마련에 대해 간호교육계 및 임상실무 현장 전반에 걸쳐 논의가 필요할 것으로 사료된다.

PURPOSE. In case of large horizontal discrepancy of alveolar ridge due to severe resorption, cantilevered crown is usually an unavoidable treatment modality. The purpose of this study was to evaluate the clinical criteria for the placement of the aforementioned implant crown. MATERIALS AND METHODS. The mandible model with 2 mm thick cortical bone and cancellous bone was fabricated from CT cross-section image. An external connection type implant was installed and cantilevered crowns with increasing offset of 3, 4, 5, 6, and 7 mm were connected. Vertical load and $30^{\circ}$ oblique load of 300 N was applied and stress around bone and implant component was analyzed. A total of 14 cases were modeled and finite element analysis was performed using COSMOS Works (Solid works Inc, USA). RESULTS. As for the location of the vertical load, the maximum stress generated on the lingual side of the implant became larger according to the increase of offset distance. When the oblique load was applied at $30^{\circ}$, the maximum stress was generated on the buccal side and its magnitude gradually decreased as the distance of the offset load increased to 5 mm. After that point, the magnitude of implant component's stress increased gradually. CONCLUSION. The results of this study suggest that for the patient with atrophied alveolar ridge following the loss of molar teeth, von-Mises stress on implant components was the lowest under the $30^{\circ}$ oblique load at the 5 mm offset point. Further studies for the various crown height and numbers of occusal points are needed to generalize the conclusion of present study.

BACKGROUND/OBJECTIVES: The purpose of this study was to investigate the overall effects of a tailored Dietary Approaches to Stop Hypertension (DASH) nutritional intervention program which included omega-3 fatty acids supplementation, on dietary self-efficacy, dietary knowledge, and dietary behaviors in Korean elderly women with abdominal obesity. Furthermore, we investigated the effects of the program on metabolic syndrome parameters including the antioxidant capacities in these subjects. SUBJECTS/METHODS: A randomized, controlled trial was conducted for 8 weeks. The experimental group (n = 21) received a weekly tailored nutritional program for 8 weeks and the control group (n = 18) received only one educational session. The clinical survey was conducted before and after the intervention period. RESULTS: After the intervention, dietary self-efficacy (P = 0.023), frequency of fruit intake (P = 0.019), and dietary fiber intake (P = 0.044) were higher in the experimental group than in the control group. The oxidative stress (P < 0.001) was lower in the experimental group than in the control group. Moreover, low density lipoprotein (LDL) cholesterol (P = 0.023) had significantly decreased in the experimental group but not in the control group after the intervention. CONCLUSIONS: The intervention program including omega-3 fatty acid supplementation had a positive effect on dietary self-efficacy, dietary behaviors, and oxidative stress among aged women with abdominal obesity.

The purpose of this quasi-experimental study was to explore the differences in the effect of aromatherapy according to the type of Sasang constitution. The subjects were fifty-three nursing students experiencing clinical practice from March 10th. 2000 to April 22nd, 2000. For experiment, researcher used inhalation of 2% grape seed oil mixed with Rosemary oil for 2 minutes and massage with same oil for 20 minutes on the back of subjects in the speed of 20 strokes per minutes. The instruments used for this study were Questionnaire of Sasang Constitution Class II program for personal computer developed by Kim Sun Ho et al., (1996), and Mood Questionnaire developed by Ryman. Biersner, & Larocco (1974). The concentration of IgA within saliva was analyzed by immunoturbidimeter assay. The data were analyzed using SPSS and hypotheses were examined with paired t-test and ANCOVA. The results were as follows : 1) The mean score of mood was increased significantly after aromatherapy. 2) The mean concentration of salivary IgA was increased significantly after aroma therapy. 3) There was no significant difference in the mean score of mood after aromatherapy according to the type of Sasang constitution, 4) There was no significant difference in the mean concentration of salivary IgA after aromatherapy according to the type of Sasang constitution. In conclusion, the results suggest that aromatherapy with Rosemary oil have effect on the improvement of mood and IgA within saliva in the nursing students under stress caused by clinical practice regardless of the type of Sasang constitution.

Students must be familiar with clinical skills before starting clinical practice to ensure patients' safety and enable efficient learning. However, performance is mainly tested in the third or fourth years of medical school, and studies using the validity framework have not been reported in Korea. We analyzed the validity of a performance test conducted among second-year students classified into content, response process, internal structure, relationships with other variables, and consequences according to Messick's framework. As results of the analysis, content validity was secured by developing cases according to a pre-determined blueprint. The quality of the response process was controlled by training and calibrating raters. The internal structure showed that (1) reliability by generalizability theory was acceptable (coefficients of 0.724 and 0.786, respectively, for day 1 and day 2), and (2) the relevant domains had proper correlations, while the clinical performance examination (CPX) and objective structured clinical examination (OSCE) showed weaker relationships. OSCE/CPX scores were correlated with other variables, especially grade point average and oral structured exam scores. The consequences of this assessment were (1) making students learn clinical skills and study themselves, while causing too much stress for students due to lack of motivation; (2) reminding educators of the need to apply practical teaching methods and to give feedback on the test results; and (3) providing an opportunity for faculty to consider developing support programs. It is necessary to develop the blueprint more precisely according to students' level and to verify the validity of the response process with statistical methods.

중등도 온열요법이 종양세포에 대한 세포독성, 종양혈관에 미치는 영향 및 면역학적 영향 등 다양한 항종양 활성을 가지고 있음에도 불구하고, 중등도 온열요법은 그 자체만으로는 항암효과가 뚜렷하지 않아, 방사선치료나 항암제 치료와 병용하여 암치료에 사용되고 있으면서, 심각한 부작용이 없이 어느 정도의 긍정적인 효과를 보이고 있다. 모든 연구에서 긍정적인 결과를 보이지 못한 것은 열충격 반응 그 자체가 온열요법의 항암효과를 방해하기 때문이다. 그러므로 온열요법의 효과를 증가시키기 위해서는 온열요법의 항암효과에 대한 부정적인 영향을 제거해야 한다. 암세포뿐만 아니라 혈관, 면역 세포 및 결체조직 등을 포함하고 있는 종양조직의 열 스트레스에 대한 반응은 매우 복잡하지만, 임상적으로 사용되고 있는 약물 중 열 스트레스 반응을 조절할 수 있는 약물들이 암환자의 온열요법 치료 효과를 개선시킬 수 있는 지에 대한 연구가 필요하다. 이 종설에서는 현재 임상에서 사용하고 있는 온열요법 장치로서 최신의 기술이며, 중등도 온도가 정상 조직에 대한 부작용 없이 기존 치료법의 효과를 증가시킬 수 있기 때문에, 비침습적 체외용 고주파 중등도 온열요법을 중심으로 다룬다.

Dental plaque resides passively at a site and makes an active contribution to the maintenance of health. The bacterial composition of plaque remains relatively stable despite regular exposure to minor environmental stress. This stability, homeostasis is due to a dynamic balance of microbial interactions. However, the homeostasis can break down, leading to shifts in the balance of the microflora. This change can be a sign of initial dental caries. It is proposed that disease can be prevented or treated not only by targeting the putative pathogens but also by interfering with the processes that drive the breakdown in homeostasis. It is essential to understand the plaque as a mixed species biofilm. In this essay I reviewed an extension of the caries ecological hypothesis to explain the relation between dynamic changes in the phenotypic/genotypic properties of plaque bacteria and the demineralization and remineralization balance of the dental caries process. We will have the strategies to impact significantly on clinical practice as understanding dental biofilm.
