Objective : The aim of this study was to find associations between specific symptoms and suicidal behavior by using global severity on depression scales. Methods : Data were obtained from 1,183 patients of CRESCEND study. Factor analysis of the 17-item Hamilton Rating Scale for Depression (HAM-D) and the Beck Depression Inventory-II (BDI-II) was used to compare symptom clusters between the past suicide attempters and the non-suicide attempters, among the patients with depressive disorders. Results : Factor analyses of HAM-D and BDI-II extracted three factors. Suicide attempters had significantly higher scores on core factor of HAM-D, including depressed mood, feeling of guilt, suicide, work, and activities. The higher scores on all factors of BDI-II or scores correlated with a total of 7 suicide attempts and with known risk factors for suicidal behavior. Conclusion : These findings suggest that the suicide attempters complained of more cognitive, affective, somatic symptoms on BDI-II, but the core factor on HAM-D was the only differentiated factor between the two groups. Clinician-rated scales as well as self-reported questionnaires were valid in measuring suicidal attempts, and the clinical profile may help in guiding the studies of biological correlates and the treatments to reduce suicide risk.

The purpose of this study was to investigate the characters' expression with clothes and the problem of creative interpretation of a historical play as a historicity and the movie costumes. This was done by comparing the role models and the situational clothes according to characters of Lee Haemyung(actor, Park Haeil) and Cho Nansil(actress, Kim Hyesoo) who were the representatives of modern generation of 1930s. The methods of this study were comparing the characters on the basis of the original novel and using the literatures, proceeding papers, internet data related to the Korean modern history and history of traditional costumes. Analysis of the costumes were divided into the scene analysis and comparing with role models. The scene analysis was done with "Modern Boy" DVD choosing the important scenes and evaluating the costumes and the expression. The comparison with role models was done with poet Baek Seok and dancer Choi Seunghee who were introduced to the official role models by film producer. Lee and Baek wore the formal suit but they have differences in silhouette and hair style. Lee had a modern sense in slim silhouette and emphasize the whimsical character with more waved style. Cho and Choi had something in common, hair style, linear silhouette, accessaries like gloves and hats, but Cho's design was more fashionable and similar as Chanel style images. Though the costumes in "Modern Boy" were made by historical researches, they were reinterpreted by the characters and images with modern feeling to raise the cinematic meanings and effects.

The objectives of this study were to: (a) examine the overall operating conditions of both government-dominant and non-governmental food bank programs, (b) understand the operational management attributes on the target based on IPA (importance performance analysis) (c) analyze the present status of donating management, and (d) suggest a direction based on the analysis of advantages and disadvantages of food banks in each part. The random samples of 120 food bank operators were selected by a proportionate stratified random sampling method. A total of 60 government-dominant food banks and 25 non-governmental food banks were analyzed. The main results of this study were as follows: According to the Importance-Performance Analysis of operational management, assistance for operating funds and deployment of experience staff were placed at Focus Here. There was a great shortage of experienced staff with food bank-specific knowledge. The average number of the government-dominant and non-governmental food bank program employees was 0.29 and 0.30 respectively, while the ratios of employees with other jobs were 0.96 and 0.83 respectively. Shortages of refrigeration facilities were an area that needs to be addressed. While 51.6% of donated food required cold storage, only 45% of government-dominant and 60% of non-governmental food bank programs had refrigeration facilities. Most of food bank operators (96.3%) were required to visit the donators` locations to pick up the donated foods. And the foods were distributed to the people in need, especially to the livelihood protectee. (Korean J Community Nutrition 11(5) : 629 ~ 641, 2006)
