본 연구는 예비교사들이 가르침의 의미를 찾아가는 과정에서 중요하게 고민하고 숙고한 것들이 무엇인지, 그리하여 그들이 구성한 가르침의 의미는 무엇인지를 드러내는 데에 목적을 두고 있다. 그리고 더 나아가 그들이 숙고하는 과정을 살펴봄으로써 예비 보육교사교육에서 예비교사들이 가르침의 의미를 구성해 갈 수 있도록 지원하기 위해 고려해야 할 요소들은 무엇인지를 찾는데 그 목적을 두고 있다. 이를 위해 M대학교 2012년 1학기 '영유아교수방법' 수업과 2학기 '보육실습' 수업을 수강한 4학년 학생 29명을 연구대상으로 선정하였다. 연구를 위한 자료 수집은 참여관찰, 인터뷰, 학생의 저널과 교수의 피드백, 소그룹 토의 등을 포함한 문서자료 수집을 통해 이루어졌다. 연구결과 예비교사들은 힘과 만만함, 집중시키는 것과 집중해 있는 것, 주기만 하기와 놓아만 두기, 그리고 차별과 평등의 극과 극 사이에서 혼돈을 겪으며 가르침의 의미를 구성해갔다. 이에 예비교사들은 가르침이란 맥락 안에서 극과 극 사이에 놓인 최적의 지점을 선택하며 끊임없이 재구성하는 과정으로, 그리고 영유아의 배움의 권리를 존중하면서 자신의 내면의 성장을 위해 노력해가는 것으로 이해하고 있었다. 더불어 예비 보육교사교육에서 가르침의 본질을 찾아갈 수 있도록 지원하기 위해서는 혼돈을 두려워하지 않는 분위기에서 다양한 관점으로 가르침을 살피며, 자유롭게 고민하는 자기만의 시간과 서로 공유하는 시간을 함께 제공해야 함이 드러났다.

The slimness favored trend made students shape up body image by weight control using restrained eating. Many students especially female ones tend to be in eating disorder status. The aim of this study was to find the relation between weight, eating habits and dietary self efficacy in the selected middle school girl students group with high risk eating disorder (7.9%) and the one with low risk eating disorder (24.1%). This study was conducted by EAT-26 questionnaire method and all the data was analyzed by SAS (Statistical Analysis System) program. The results were as follows; The physical condition of eating disorder students (159.5cm height, 50.7kg weight and 97.4% PIBW) was higher and bigger than that of normal students(158.2 cm, 47.2 kg, and 92.6% PIBW). Weight control experience in the high risk group (69.4%) was significantly more frequent than normal group (p<0.001). The gap between actual body weight and desired weight was higher in high risk eating disorder group than in normal group (p<0.001). Dietary self-efficacy score of middle school female students in the high risk eating disorder group was high when they were in temper, in confusion, and after argument. However, when they were in cooking (p<0.01), with friends (p<0.05), in assembling dishes (p<0.01), and with family (p<0.05) the dietary self-efficacy score of high risk group was lower than that of normal group. In the high risk eating disorder group, eating speed was often faster (p<0.05) and overeating rate (p<0.01) was higher than in normal group. In general, EAT-26 score was correlated positively with gap weight, but negatively correlated with dietary self efficacy score(p<0.01). Gap weight and dietary self efficacy were significantly different in normal group. however, there was no relation in high risk eating disorder group. Under the circumstance of high risk eating disorder, as weight and dietary self efficacy did not affect the relation with eating disorder score, when it is determined as eating disorder some other factors besides weight and diet self efficacy seem to affect the eating disorder score. In conclusion, the factors related with eating disorder were gap weight and some items of dietary self efficacy. Thus, correct understanding of healthy weight and dietary self efficacy enhancement require the development of nutrition education contents and the practice of nutrition education.

This study was to provide understanding for the juvenile problem of drug brought about by industrialization, and the importance people that we should take a role in helping to resolve the problem. The purpose of this study lies in approaching the effective methods to prevent Korean adolescents from being involved in drug by examining the factors of their experience. The method of this study is designed to grasp the adolescents' drug experience, its meaning, its structure and the nursing intervention ways. By applying a phenomenological approach which is based on a qualitative research method, the researchers hoped to reveal key data in each group. It has been carried on from October 1998 until September 1999 with sample of 5 adolescent inmates in K mental hospital located in Seoul. The data were collected by sereous personal deep interviews and observations. Collected data were analyzed according to the phenomenological method suggested by Giorgi. The results of this study are as follows: First, pleasure seeking: curiosity, joy, and fun; Second, affiliation: formation of clique with the same age; Third, escape from reality: loneliness, emptiness, heroic mind, self- confidence, self-absorption, and comfort; Forth, feeble- mindedness: anxiety, fear, and temptation; Fifth, psychological unadaptation: wandering, forfeiture, and incompetence; Sixth, physical counteraction: headache, vomiting, loss of memory, loss of appetite and loss of sensibility; Seventh, psychological confusion: illusion, auditory hallucination and dream; Eighth, recovery of self-consciousness: repentance, desire and awareness This study results in the following suggestions of the nursing intervention 1. To cultivate a wholesome game culture for the adolescents. 2. To make up the group activities so that the adolescents can establish their sense of identity through a variety of group counseling program. 3. To foster the capability to cope with the change in the process of social accommodation. 4. To enforce the social life skill for the adolescents. 5. To practice the systematic education about drug use. 6. To develop the social education programs. 7. To help the adolescents build up their sense of identity by applying the adolescent cure programs. Above all, it is necessary that school and community as well as home should establish the educational environment paying special concern and consideration to the adolescents.

Objectives : The term ByunJeung is usually used to represent the characteristic of Korean Medicine. However the meaning of ByunJeung has not been consistent. After the 1980s when Traditional Chinese Medicine was introduced into Korea, the meaning of ByunJeung in Korea became diverse. In this paper, we aimed to research how the meaning of ByunJeung has been varied. Methods : We used four major journal database in Korea to search articles related to ByunJeung. Using the terms such as "변증" and "辨證", which mean ByungJeung in Korean and Chinese, we collected 500 articles in total. Among them, we chose only 61 articles selectively which mainly focused on the meaning of ByunJeung. We categorized those according to the specific meaning of ByunJeung which each article used, and qualitatively analyzed those articles. Results : Articles related to ByunJeung were categorized into three different groups. The first group was for the articles which dealt with changing meanings of ByunJeung. The second group was for the articles which focused on the modernized meaning of ByunJeung. The third group was for the articles which was on the traditional meaning of ByunJeung. Conclusions : The term ByunJeung holds a key concept in the current field of Korean medicine. Nevertheless, since the meaning of ByunJeung has been diverse, it often caused confusion among the people who used the term ByunJeung. Therefore we need to clarify the exact meaning when we intend to use the term. Also there should be a further discussion on the meaning of ByunJeung in the field of Korean medicine to facilitate better understanding on the characteristic of Korean medicine.

Background: Delirium after cardiac surgery is associated with serious long-term negative outcomes and high costs. The aim of this study is to evaluate neurobehavioral, hemodynamic, and sedative characteristics of dexmedetomidine, compared with the current postoperative sedative protocol (remifentanil) in patients undergoing open heart surgery with cardiopulmonary bypass (CPB). Methods: One hundred and forty two eligible patients who underwent cardiac surgery on CPB between April 2012 and March 2013 were randomly divided into two groups. Patients received either dexmedetomidine (range, 0.2 to $0.8\;{\mu}g/kg/hr$; n=67) or remifentanil (range, 1,000 to $2,500\;{\mu}g/hr$, n=75). The primary end point was the prevalence of delirium estimated daily via the confusion assessment method for intensive care. Results: When the delirium incidence was compared with the dexmedetomidine group (6 of 67 patients, 8.96%) and the remifentanil group (17 of 75 patients, 22.67%) it was found to be significantly less in the dexmedetomidine group (p<0.05). There were no statistically significant differences between two groups in the extubation time, ICU stay, total hospital stay, and other postoperative complications including hemodynamic side effects. Conclusion: This preliminary study suggests that dexmedetomidine as a postoperative sedative agent is associated with significantly lower rates of delirium after cardiac surgery.

According to technology acceptance model(TAN) which is one of the most important research models for explaining IT users' behavior, on intention of using IT is determined by usefulness and ease of use of it. However, TAM wouldn't explain the performance of using IT while it has been considered as a very good model for prediction of the intention. Many people would not be confirmed in the performance of using IT until they can control it at their will, although they think it useful and easy to use. In other words, in addition to usefulness and ease of use as in TAM, controllability is also should be a factor to determine acceptance of IT. Especially, there is a very close relationship between controllability and ease of use, both of which explain the other sides of control over the performance of using IT, so called perceived behavioral control(PBC) in social psychology. The objective of this study is to identify the relationship between ease of use and controllability, and analyse the effects of both two beliefs over performance and intention in using IT. For this purpose, we review the issues related with PBC in information systems studies as well as social psychology, Based on a review of PBC, we suggest a research model which includes the relationship between control and performance in using IT, and prove its validity empirically. Since it was introduced as qa variable for explaining volitional control for actions in theory of planned behavior(TPB), there have been confusion about concept of PBC in spite of its important role in predicting so many kinds of actions. Some studies define PBC as self-efficacy that means actor's perception of difficulty or ease of actions, while others as controllability. However, this confusion dose not imply conceptual contradiction but a double-faced feature of PBC since the performance of actions is related with both self-efficacy and controllability. In other words, these two concepts are discriminated and correlated with each other. Therefore, PBC should be considered as a composite concept consisting of self-efficacy and controllability, Use of IT has been also one of important areas for predictions by PBC. Most of them have been studied by analysis of comparison in prediction power between TAM and TPB or modification of TAM by inclusion of PBC as another belief as like usefulness and ease of use. Interestingly, unlike the other applications in social psychology, it is hard to find such confusion in the concept of PBC in the studies for use of IT. In most of studies, controllability is adapted as PBC since the concept of self-efficacy is included in ease of use explicitly. Based on these discussions, we can suggest perceived use control(PUC) which is defined as perception of control over the performance of using IT and composed of controllability and ease of use as sub-concepts. We suggest a research model explaining acceptance of IT which includes the relationships of PUC with attitude and performance of using IT. For empirical test of our research model, two user groups are selected for surveying questionnaires. In the first group, there are freshmen who take a basic course for Microsoft Excel, and the second group consists of senior students who take a course for analysis of management information by Excel. Most of measurements are adapted ones that have been validated in the other studies, while performance is real score of mid-term in each class. In result, four hypotheses related with PUC are supported statistically with very low significance level. Main contribution of this study is suggestion of PUC through theoretical review of PBC. Specifically, a hierarchical model of PUC are derived from very rigorous studies in the relationship between self-efficacy and controllability with a view of PBC in social psychology. The relationship between PUC and performance is another main contribution.

Purpose: Screening of delirium using delirium assessment tools could promote delirium detection, however, there is lack of report about regular delirium assessment in Korea. This study was intended to describe the prevalence and related risk factors of delirium in intensive care unit (ICU). Methods: The Confusion Assessment Method for the ICU (CAM-ICU) data which were evaluated by nurses in ICUs was obtained through retrospective chart review. Data were analyzed using descriptive statistics, Chi-square test, t-test, Mann-Whitney U test, and stepwise logistic regression. Results: Delirium was evaluated in 125 patients. The incidence rate of delirium was 27.2% with a high prevalence of hypoactive delirium compared to hyperactive delirium (61.8 vs. 38.2%). Those with delirium were older, had hypertension, stayed longer in hospital, receiving ventilator support, had more number of catheters, had low serum protein and albumin level. Delirium incidence also varied according to diagnosis. Age, diagnosis of gastrointestinal disease, and application of ventilator were the significant risk factors for the incidence of delirium. Conclusion: Routine delirium screening is important for early detection of delirium. Identification of high-risk group and running delirium prevention programs could improve early recognition of delirium in ICU.

Purpose: The purpose of this study was to explore and identify patterns from the phenomenon of the role adaptation process in elementary school health teachers and finally, suggest a model to describe the process. Methods: Grounded theory methodology and focus group interviews were used. Data were collected from 24 participants of four focus groups. The questions used were about their experience of role adaptation including situational contexts and interactional coping strategies. Transcribed data and field notes were analyzed with continuous comparative analysis. Results: The core category was 'establishing their own positions', an interactional coping strategy. The phenomenon identified by participants was confusion and wandering in their role performance. Influencing contexts were unclear beliefs for their role as health teachers and non-supportive job environments. The result of the adaptation process was consolidation of their positions. Pride as health teachers and social recognition and supports intervened to produce that result. The process had three stages; entry, growth, and maturity. Conclusion: The role adaptation process of elementary school health teachers can be explained as establishing, strengthening and consolidating their own positions. Results of this study can be used as fundamental information for developing programs to support the role adaptation of health teachers.

Parotid canalicular adenoma is a benign neoplasm that is predominantly composed of branching and interconnecting cords of single or double rows of columnar epithelium in a very loose stroma. There has been considerable confusion in the literature concerning the terminology of canalicular adenoma. However, thesedays it has been newly-recognized as a discrete entity of the monomorphic adenoma group. Canalicular adenoma has a remarkable predilection for occurrence in the minor salivary glands such as the upper lip, in contrast with basal cell adenoma that occurs predominantly in major salivary glands such as the parotid gland. We have experienced a case of canalicular adenoma of the parotid gland in a 65-year-old woman. The patient had a palpable mass on the preauricular area for the last 15 years and recently noticed a mild pain and discomfort on the mass. Neck ultrasonography showed a low echogenic mass of 1.0cm in diameter in the right parotid gland and a neck CT scan showed a well-enhanced rectangular-shaped mass. A superficial parotidectomy was performed for the lesion and the final pathologic diagnosis turned out to be 'multifocal canalicular adenoma'.
