지금까지 향의 이미지에 따른 감성 평가에 관한 연구, 특히 성별에 따른 차이에 관한 연구는 거의 없었다. 본 연구는 향의 이미지에 따른 성별 감성 차이를 분석하기 위하여 네 가지 향 (Jasmin abs, Rose oil bulgalian, Lavender oil france, Lemon oil misitano)을 제시하고 그에 따른 주관적 평가를 분석하였다. 후각 실험 및 주관적 평가는 20-26세의 남자10명, 여자10명으로 구성된 피험자를 대상으로 이루어졌고, 주관적 평가는 향의 세부적인 이미지를 나타내는 후각 감성 형용사를 이용하여, 양극의 7점 척도 25문항, 단극의 5점 척도 40문항, 그리고 각 향의 전반적인 선호도를 묻는 양극의 7점 척도 2문항으로 구성하였다. 본 연구 결과에 의하면 남성과 여성 모두 Lemon향을 가장 쾌한 감성의 향으로, Rose향을 가장 자극적인 향으로 생각하는 것과 같은 심리척도의 보편적인 정서인 쾌/불쾌, 자극/진정의 감성에 있어서 성별에 따른 차이를 별로 보이지 않았다. 그러나, 여성에 비해 남성이 Rose향을 정열적이고 화려한 향으로 느낀다거나, Jasmin 향에 대하여 남성은 여성적인 향으로 생각하는 반면, 여성은 Jasmin 향을 남성적인 향으로 평가하는 등 각 향에 대한 세부적인 이미지에는 여성과 남성이 뚜렷한 차이를 보이고 있었다.

The magnetic compass as a principal navigational instrument has been long used to fix ship's position and to determine ship's course. Particularly, in the small fishing vessels the studies on performance and rational usages for magnetic compass are requried to improve the safety and productivity of the small fishing vessels even though gyro compass is developed nowadays. For this purpose, the author examined the present condition of the magnetic compasses which are intalled on 219 small fishing vessels, and carried out a series of performance survey for each compass of them and also found the measured values of deviation by installation position of compass, respectively. The results obtained are summarized as follows: 1. The small fishing vessels less than 4 tons among the 219 small fishing vessels from 1 to 10 tons investigated were 50% of them. Only 1% of them were equipped with the deviation correctors, and 14 fishing vessels used the magnetic compasses which are more than 20 years old. 2. According to the compass installation position, the measured values of the deviation of the compass installed on the top bridge and the compass bed in bridge were ascertained to be the smallest, and those values of the compass installed on the bridge deck above engine room were larger and irregular. 3. The concomitant angle of the magnetic compasses installed on the experimented 4 fishing vessels were measured to be 6$^{\circ}$ to 16$^{\circ}$ and not accorded with the Korean standard values.

Objective : This study was designed to find the characteristics of MMPI that could influence the outcome of cognitive behavioral therapy(CBT) for panic disorder. Methods : 34 patients who met DSM-IV criteria for panic disorder with or without agoraphobia had completed 11 weekly sessions of cognitive behavioral therapy. All the patients were assessed with MMPI before the initiation of treatment. Five self-report measures including Beck Depression Inventory(BDI), Spielberger State-Trait Anxiety Inventory(STAI), Agoraphobic Cognition Questionnarie(ACQ), Body Sensation Questionnaire(BSQ), and Daily Anxiety Selfrating (0 - 8 scales) were also assessed as a pre- and post-treatment assessment. After the completion of treatment, patients were classified by the High End-State(HES) functioning group and the Low End-State(LES) functioning group for the data analysis. Results : 1) The LES group showed significantly higher scores in Hypochondriasis Scale(HS), Depression Scale(D), Hysterical Scale(Hy), Obsessive Scale(Pt), Schizophrenia Scale(Sc) and Validity Scale(F) of MMPI than the HES group. However, these differences gave impressions that the LES group had more severe symptoms rather than that they could be the factors influencing the outcome of CBT. 2) Though, the severity of symptoms of the LES group in the 5 measures of pre-assessment was basically higher than that of the HES group. The fact that both group showed the similar improvement between pre- and post-assessment supported the above interpretation. Conclusion : In regarding the above results, MMPI was not a proper tool that could provide the factors influencing the outcome of CBT. In the future study, the authors need to use a different tool that can find the personality characteristics more directly.

The aim of this study was to assess effects of aromatherapy on anxiety and depression of caregivers for patients in rehabilitation therapy and to provide basic data for the aromatherapy. Beck Anxiety Inventory(BAI) and Beck Depression Inventory(BDI) for the preliminary assessment of anxiety and depressive mood were administered to caregivers for patients in rehabilitation therapy in Chungbuk National University Hospital. Forty two out of seventy subjects who got scores above 10 in BDI were selected. Forty two Participants were divided into orange group, lavender group and control group. They had got the aromatherapy by using the lamp diffusion method for 4 weeks. Only forty participants completed a trial. Effects of the aromatherapy were measured using BAI, Hamilton Anxiety Rating Scale(HAM-A), BDI, Hamilton Depression Rating Scale(HAM-D), Self Esteem Scale(SES) and Index of Wellbeing(IOWB) before and after the aromatherapy. Orange group showed significant difference in the change of BDI scores compared with control group. Lavender group showed significant difference in the mean change of BAI, BDI and IOWB scores compared with control group. These results suggested that aromatherapy with orange oil was effective for depression and the aromatherapy with lavender oil was effective for anxiety as well as depression.

Objectives：This study was done as a part of investigating individual and socioenvironmental factors affecting test anxiety in adolescent. The focusing of this study was detecting specific family enviromental factors affecting worry and emotionality of test anxiety. Methods：The subjects of this study were 880 middle and high school students in Seoul, Korea. To evaluate test anxiety level, Spielberger's Test Anxiety Inventory was applied and to evaluate familial factor, Moos and Moos' Family Environmental Scale was done. Results：The results were as follows. 1) Total and worry part of test anxiety scores were negatively correlated with cohesion and independence scores. Total, worry, and emotional part of test anxiety scores were positively correlated with achievement orientation and control scores. 2) High test anxiety group showed higher achievement orientation and control scores, and lower cohesion scores than low test anxiety group. 3) The higher socioeducational level of parents were, the higher three subscale (cohesion, independence, and achievement orientation) scores were, except control score. Conclusion：In therapeutic approach of adolescent's test anxiety, the importance of education and treatment of their parents should be emphasized. Parents should set their children's appropriate achievement goal, encourage their children's independency instead of control. Cohesion of familial members are also needed.

This study aims to identify constructs of cultural competency specifically relevant to the Korean society and to test its reliability and validity among human service workers. For the purpose of the study, authors conducted focus group interviews and conferences with human service workers to draw the concept of cultural competency. Further, this study conducted to two separate pilot tests with 20 social workers with practice experiences in order to clarify descriptions and relevance of scale items. Based on the literature review on the concept of cultural competency and analysis of focus group interviews, 40 items were initially constructed and then were reduced to a 32-item scale after two separate pilot studies. Meantime, suggestions made by an advisory group were also reflected in the scale development process. Finally, one hundred ninety four workers in social service agencies were recruited to evaluate the relevance of the scale items in a 5 point Likert scale. Through exploratory and confirmatory factor analysis, 4 main factors were identified: 1) competency to use culturally relevant skills, 2) cultural awareness and sensitivity, 3) cultural knowledge, and 4) efforts to overcome cultural differences. These factors were consistent with sub-concepts of cultural competency in other studies. Confirmatory factor analysis also showed that the model fitness was at the high level and convergent analysis with the similar scale also showed high correlations. Internal consistency also remained at a high level. Based on the results, implication for social work practice and education were discussed.

The purpose of this study was to develop and validate Korean version of Deaf Acculturation Scales(DAS). Pilot items were made a faithful translation of the Acculturation Scales of Maxwell-McCaw and Zea (2011) and were modified for Korean Deaf people. The Scale involves two dimensions, in order to measure the acculturation of Deaf people; Deaf acculturation and hearing acculturation. Using factor analysis, we developed a Korean version of DAS consisted of twenty-five items for Deaf acculturation dimension and twenty-five items for hearing acculturation dimension. These analysis supported the four factors of Deaf acculturation dimension and the five factors of hearing acculturation dimension. Reliability, assessed by Cronbach's ${\alpha}$, was .93 for Deaf acculturation and .93 for hearing acculturation, respectively, which confirm the Koran version of DAS. Construct validity was demonstrated through correlation with Deaf acculturation-related variables: age, age of Deafness, Degree of hearing loss, American Sign Language ability, and lip-reading ability. Criterion validity was supported by correlation with Collective Self-Esteem Scale. Limitation and implication of this study and direction for future research were discussed.
