The purpose of this study was to identify how nurse's image was perceived by nursing college students. The subjects included were 315 students experienced clinical practice during $20{\sim}22$ weeks and 134 students not with a total of 449 nursing students in Gwangju and Chonnam. The data were collected from November 21 to December 5, 2001 by the structured questionnaires. The research tool was measured by 30 items divided into four dimensions; traditional, professional, social and personal image of nurse. Cronbach $\alpha$ for the tool of nurse's image was 0.8960. The data were analysed by SPSS 8.0 for Windows program using frequency, percentage, mean, standard deviation, t-test, ANOVA and scheffe. The results of this study were as follows; 1. In the nurse's image related to general characteristics, there were significant differences for school graduation, applicative motivation, interpersonal relationship and image forming factor. 2. In the Image forming factors, nursing college students perceived the nurse's image by visiting hospital or admission(37.9%), watching TV(25.8) and others; nurses' appearance during clinical experience(16.3). 3. The mean score for nurse's image of clinical experience group (2.76$\pm$0.28) was lower than that of non-clinical experience group(2.89$\pm$0.31) in significance (t=4.319, p=0.000). 4. In the nurse's image according to clinical experience, there were significant differences for traditional, professional, social, personal image between two groups and the lower mean scores were found in the clinical experience group in all dimensions. The ranks of dimensions were professional image(3.08), traditional image(2.76), social image(2.65), the personal image(2.59) in clinical experience group, whereas professional image(3.21), traditional image(2.93), social image(2.75), personal image(2.71) for non-clinical experience group.5. The high score items of nurse's image were 'worthwhile work(3.48)', 'always working hard(3.30)', 'profession(3.17)', 'strong responsibility toward work(3.08)', 'have a high technical skill(3.05)' in clinical experience group and 'worthwhile work(3.69)', 'always working hard(3.28)', 'clean and decent(3.22)', 'profession(3.21)', 'have a bountiful professional knowledge(3.18)' in non-clinical experience group. 6. The highest mean score for nurse's image related to the image forming factors was 86.8 by novels or literature and the second highest was 84.3 by visiting hospital or admission. And others(mean=82.1)was the most negative nurse's image by clinical experience. In conclusion, nurse's image perceived by nursing college students will be the mirror of themselves. And clinical experience will be the important opportunity to form the professional image with white uniformed nurses in future. Therefore it is important for clinical nurses to play professional roles rightly so that nursing students could form positive nurse's image.

20세기 디자이너들이 평범한 오브제나 제품을 창조적인 새로운 비전으로 변형해 온 방법들은 외형적으로는 무한해 보이지만, 디자이너들은 어떤 기본적인 공식을 따르는 것으로 보인다. 그러한 공식중에서 두드러진 방법이 변형이라고 할 수 있다. 본 논문에서는 변형이 갖는 의미를 살펴보고, 여러 가지 디자인 사례들에 대한 분석과 디자이너들이 사용해 왔던 변형방법들을 살펴본 후, 다음과 같은 결론을 얻을 수 있었다. 받침대, 손잡이, 병의 주둥이와 같은 기능을 갖는 요소들의 의미가 바뀌거나 크기가 과장되기도 한다. 또한, 디자이너들은 우리가 일반적으로 금속, 유리, 또는 그 외의 재료들에서 기대하는 것을 강조한다. 즉, 단단한 재료를 부드럽게 보이게 하고, 부드러운 재료를 단단하게 보이게 하거나, 특정 재료에 적합한 기술을 다른 재료에 전가시키기도 한다. 결론적으로, 디자인에 있어서의 변형(transformation)은 디자이너들의 창조적 작업을 위한 주요한 방법임을 확인할 수 있었다.

This investigation was designed to determine the effectiveness of the posterior occlusal schemes on masticatory activity during mastication in complete denture. Twelve edentulous subjects were selected for this study. All subjects had no past history and no functional abnormality on masticatory system and TMjoint. And, they had residual ridge of favorable morphology, firm mucosa and Class I skeletal jaw relationship, Twelve experimental denture with interchangeable occlusions(0-degree teeth, 30-degree teeth, Levin teeth and S-A teeth) were constructed for this study. The masticatory performance was analyzed by means of standard sieve(10, 16, 20, 30sieve), and the electrical activity from selected muscles(Temporalis and Masseter muscle) was recorded simultaneously with electromyography (Bio-Pak system) as the subject masticated test foods (rice, peanut and gum) with four different occlusal schemes. Mandibular movement was, also, measured with Sirognathography(Bio-Pak system). These recordings were performed in immediately, after 1 week and after 2 weeks of insertion of complete denture. The results were as fellows; 1. The average masticatory performance of 0-degree artificial teeth was higher than any other artificial teeth. 2. Masticatory performance in denture wearer was affected preferentially by food and artificial occlusal schemes. 3. During chewing, there was a statistical difference of EMG activity between masseter and temporal muscle(p<0.01). Especially, EMG activity of working masticatory muscle was highly affected by food rather than by artificial occlusal schemes. 4. In denture wearer, the velocity of opening was not affected by food, whereas, the velocity of closing was faster in soft food chewing than in hard food chewing, and the amount of vertical displacement was grater in chewing of soft and large bolus than in chewing of hard and small bolus. However, the amount of lateral displacement showed conversely(p<0.05). 5. It was considered that masticatory performance in denture wearer is not affected by the condition of residual ridge. the history of denture wear, the preference, the adaptation to artificial teeth and the total mesiodistal length of artificial posterior teeth.

Clinical and epedemiologic studies of coronary heart disease(CHD)have from time to time over the last three decades found associations between prevalence of CHD and behavioral attributes and cigarette smoking. The main purpose of this study is reduced to major risk factor of coronary heart disease through prohibition of smoking and control of behavior pattern. The subjects consisted of 120 smokers and 90 non-smokers who were married men older than 30 years working in officers. The officers were surveyed by means of questionnaire September 26 through October 6, 1989. The Instruments used for this study was a self-administered measurement tool composed of 59 items was made through modifications of Jenkuns Activity Survery(JAS). The Data were analysed by SAS(Statistical Analsis System) program personal computer. The statistical technique used for this study were Frequency, x$^2$-test, t-test, ANOVA, Pearson Correlation Coefficient. The 15 items were chosen with items above 0.3 of the factor loading in the factor analysis. In the first factor analysis 19 factors were extracted and accounted for 86% of the total variance. However when the number of factors were limited to 3 in order to derive Jenkins classification, three factors were derived. There names are Job-Involvement, Speed & Impatience, Hard-Driving. Each of them includes 21 items, 21 and 9, respectively. The results of this study were as follow : 1. The score of the smoker group and non-smoker group in Job-Involvement(t＝5.7147, p＜0.0001), Speed & Impatience(t＝4.6756, p＜.0001), Hard-Driving(t＝8.0822, p＜.0001) and total type A behavior pattern showed statistically significant differences(t＝8.1224, p＜.0001). 2. The score of type A behavior pattern by number of cigarettes smoked daily were not statistically significant differences. 3. The score of type A behavior pattern by duration of smoking were not significant differences. It was concluded that the relationship between smokers and non - smokers of type A behavior pattern was statistically significant difference but number of cigarettes smoked daily and duration of smoking were not significant differences. Therefore this study is needed to adequate nursing intervention of type A behavior pattern in order to elevated to educational effect for prohibition of cigarette smoking.

저자는 열성형재료와 진공성형기를 이용하여 소아치과 임상에서 사용되는 수 종의 장치를 제작하였다. 전공성형기의 구입에 따른 경제적인 부담은 있으나, 기존의 제작법에 비해 제작이 간편하여 시간이 단축될 뿐 아니라 plate 의 두께가 균일하므로 finishing이 거의 필요하지 않으며 더욱 심미적인 장치를 제작할 수 있다. 또한 조직과 접촉하는 부위는 soft한 열성형재료를 사용하여 치아 이동에 유리할 뿐 아니라, 기존의 resin에 비해 불쾌한 맛이 적다는 장점이 있다. Monomer가 없어 조직에 자극이 적고 mutagenous potential이 없으므로 생체 적합성이 뛰어나 조직의 적응이 용이하다. 복잡하거나 특수한 기능 및 견고성이 필요한 악기능교정 장치 등에서는 그 사용이 제한된다는 한계점이 있으나, 소아치과 임상에서 사용되는 대부분의 장치를 쉽고 간편하게 제작할 수 있어 앞으로 임상에서 널리 이용될 수 있을 것으로 생각된다.

현재 한국은 세계 190여개 국가와 수교하였고, 113개 국가에 해외공관을 개설하였으며, 한국군은 국제 평화 유지를 위해 다국적군 평화활동 국방협력활동 UN평화유지활동 등을 통하여 그 위상을 국제사회에 널리 알리고 있다. 그러나 이러한 이면에는 정치 종교 이념 등의 목적을 실현하기 위한 테러조직 무장단체 등과 개인 경제적 원인에 의한 강력범죄가 발생하여, 해외에서 활동하는 우리 국민에게 막대한 피해를 주고 있다. 이에 본 연구에서는한국을 대상으로 발생한 국제테러리즘의 피해사례에 대한 경향분석을 실시하였다. 그 시사점과 결론을 살펴보면 다음과 같다. 우선, 해외에서 우리 국민의 안전을 위협하는 공격주체는 무장단체, 극단주의자 등으로 나타났다. 그러나 이를 신속하고 정확하게 분석 및 대응할 수 있는 전문 인력이 부족한 것이 현실이므로, 지속적인 전문가 양성과 매뉴얼 개발이 시급하다고 할 수 있다. 다음으로, 해외에서 발생하는 피해대상이 과거와 비교하여 경성목표(hard targets)에서 연성목표(soft targets)로 변하고 있다. 이는 국가기관에 의한 국민의 기본권 제한에 문제가 발생할 수 있으므로, 시민 스스로가 여행금지 등의 지역을 가지 않는 성숙된 시민의식이 필요하다고 본다.

Tribological behaviors of the hard film on soft substrate system were explored using the hard thin film of diamond-like carbon (DLC) coated the soft polymer of polydimethysiloxane (PDMS). A DLC film with the Young's modulus of 100 GPa was coated on PDMS substrate with Young's modulus of 10 MPa using plasma enhanced chemical vapor deposition (PECVD) technique. The deposition time was varied from 10 sec to 10 min, resulting in nanoscale roughness of wrinkle patterns with the thickness of 20 nm to 510 nm, respectively, at a bias voltage of $400\;V_b$, working pressure 10 mTorr. Nanoscale wrinkle patterns with 20-100 nm in width and 10-30 nm height were formed on DLC coating due to the residual stress in compression and difference in Young's modulus. Nanoscale roughness effect on tribological behaviors was observed by performing a tribo-experiment using the ball-on-disk type tribometer with a steel ball of 6 mm in diameter at the sliding speed of 220 rpm, normal load of 1N and 25% humidity at ambient temperature of $25^{\circ}C$. Friction force were measured with respect to thickness change of coated DLC thin film on PDMS. It was found that with increases the thickness of DLC coating on PDMS, the coefficient of friction decreased by comparison to that of the uncoated PDMS. The wear tracks before and after tribo-test were analyzed using SEM and AFM.

Purpose : The purpose of this study was to identify the degree of work ethics of an occupational therapist and examine the correlation between work ethics and organizational commitment. In this study, we aimed to investigate the effects of occupational therapists' work ethics on organizational commitment. Through this study, we aim to determine the importance of work ethics and find a way to improve organizational commitment in occupational therapists. Methods : We conducted nationwide surveys on occupational therapists working in hospitals and other institutions from April 24, 2023 to May 30, 2023. We evaluated general characteristics, work ethics, and organizational commitment. General characteristics were analyzed using a frequency analysis. Work ethics and organizational commitment were examined using descriptive statistics. The correlation among work ethics and organizational commitment was analyzed using the Pearson correlation coefficient. Additionally, a multiple regression analysis was conducted to identify factors that affected organizational commitment. Results : The results of this study were as follows. First, the average score of work ethics was 3.32 ± .32. Second, a significant positive correlation was observed between work ethics and organizational commitment (p<.01). And as a result of the correlation between work ethics sub-factors and organizational commitment, wasted time (r=.261, p<.01), centrality of work (r=.366, p<.01), morality/ethics (r=.470, p<.01), leisure (r=.189, p<.05), delay of gratification (r=.410, p<.01), hard work (r=.437, p<.01), self-reliance (r=.233, p<.01) showed a statistically significant correlation. Third, the sub-factors of work ethics that influenced organizational commitment, including morality/ethics (𝛽=.302, p<.01), hard work (𝛽=.271, p<.01), and delay of gratification (𝛽=.205, p<.01) were identified. Conclusion : In conclusion, the results of this study underscore the importance of work ethics in influencing organizational commitment. Through this study, we recognized the importance of work ethics, which may serve as basic data to promote work ethics and improvement of organizational commitment.
