Purpose: The purpose of this study is to understand the depression of patients for Fibromyalgia Syndrome(FMS) and to identify the factors influencing depression. Method: The instruments used here are Beck Depression Inventory in depression, the Korean Rheumatology Health Association' instruments in Self-Efficacy. Also, Pain and Fatigue was measured by Visual Graphic Rating Scale. The subject of study is 76 outpatients diagnosing FMS from rheumatism specialists at C hospital in D city. The data has been collected from Sep. 1st to Sep. 30th in 2001. For the analysis of collected data, frequency analysis, independent t-test, analysis of variance, Pearson's correlation and multiple regression analysis were used for statistical analysis with SAS statistical program. Result: General characteristics showing statistically significant difference in depression were age, education, occupation, gender, exercise and sleep in the patients with FMS. Depression for the patients with FMS has negative correlation coefficients with Self-efficacy and ADL, and positive correlation coefficients with Pain and Fatigue. The suitable regression form resulting from the multiple regression analysis to investigate the influencing factors of depression for the partients with FMS was expressed by y =50.067 - 0.278x$_1$ + 1.320x$_2$ (x$_1$: Self-Efficacy x$_2$: Fatigue) and $R^2$ =0.427. Conclusion: The factors influencing on depression of patients for FMS was Self-Efficacy, ADL, Pain, and Fatigue. Further study needs to be done identify methods of overcoming and presentation of depression in FMS.

This paper presents an internet-based self-learning educational system which can be enhancing efficiency in the learning process of Java language. The proposed self-learning educational system is called Java Web Player(JWP), which is a Java application program and is executable through Java Web Start technologies. In this paper, three important sequential learning processes : concept learning process, programming practice process and assessment process are integrated in the proposed JWP using Java Web Start technologies. This JWP enables the learners to achieve efficient and interesting self-learning since the learning process is designed to enhance the multimedia capabilities on the basis of educational technologies. Also, online voice presentation and its related texts together with moving images are synchronized for efficient language learning process. Furthermore, a simple/useful compiler is included in the JWP for providing language practice environment such as coding, editing, executing and debugging Java source files. Finally repeated practice can make the learners to understand easily the key concepts of Java language. Simple multiple choices are given suddenly to the learners while they are studying through the JWP and the test results are displayed on the message box.

Background: A major problem with cervical cancer screening in countries which have no organized national screening program for cervical cancer is sub-optimal participation. Implementation of self-sampling method may increase the coverage. Objective: We determined the agreement of cytological diagnoses made on samples collected by women themselves (self-sampling) versus samples collected by physicians (Physician sampling). Materials and Methods: We invited women volunteers to undergo two procedures; cervical self-sampling using the Evalyn brush and physician sampling using a Cervex brush. The women were shown a video presentation on how to take their own cervical samples before the procedure. The samples taken by physicians were taken as per routine testing (Gold Standard). All samples were subjected to Thin Prep monolayer smears. The diagnoses made were according to the Bethesda classification. The results from these two sampling methods were analysed and compared. Results: A total of 367 women were recruited into the study, ranging from 22 to 65 years age. There was a significant good agreement of the cytological diagnoses made on the samples from the two sampling methods with the Kappa value of 0.568 (p=0.040). Using the cytological smears taken by physicians as the gold standard, the sensitivity of self-sampling was 71.9% (95% CI:70.9-72.8), the specificity was 86.6% (95% CI:85.7-87.5), the positive predictive value was 74.2% (95% CI:73.3-75.1) and the negative predictive value was 85.1% (95% CI: 84.2-86.0). Self-sampling smears (22.9%) allowed detection of micro-organisms better than physicians samples (18.5%). Conclusions: This study shows that samples taken by women themselves (self-sampling) and physicians have good diagnostic agreement. Self-sampling could be the method of choice in countries in which the coverage of women attending clinics for screening for cervical cancer is poor.

Purpose : The purpose of this study was to determine the influence of the elastic-band exercise program for elderly who over 65 years old in terms of depression and physical self efficacy. We aim to suggest interventions with an elastic-band exercise program for elderly. Methods : The study subjects selected were females or males 65 years old or more who could walk without assistance and could talk about daily living without mental or physical disorders. A total of eight subjects understood the purpose of this study and agreed to participate. Before and after the exercise program, the subjects were monitored for changes in their physical self-efficacy and depression. To measure the physical self-efficacy, we used a perceived physical ability scale and physical self-presentation confidence scale (Cronbach α =0.942). To measure depression, we used the geriatric depression scale short form (Korea version, Cronbach α =0.969). The data obtained from each measure were analyzed using the Wilcoxon signed rank test to determine changes from before and after the exercise program. The program consisted of three parts (warm-up, main exercise and cool-down) and included the upper extremities, the lower extremities and trunk exercises with an elastic band (yellow and red). The program lasted for 15 weeks, once a week, with each session lasting for 60 minutes. Results : After 15 weeks of the elastic-band exercise program, there was a significant decrease on the depression scale (p<0.05) and significant improvements on the physical self-efficacy scale (p<0.05). Conclusion : Based upon our results, we demonstrated that the exercise program using the elastic band was effective in improving the depression and physical self-efficacy of the elderly.

Purpose: This study was done to analyze and clarify the concept of empathy in nursing. Methods: Using the concept analysis framework of Walker & Avant 68 articles about empathy were selected for this study. Results: Defining attributes of empathy included recognizing others' perspective and thought, understanding others' emotion, and communicating with them. The antecedents of empathy included contact with patients, respect and trust for patients, a certain level of cognitive ability, and communication skills. Consequences of empathy were increasing patient self-understanding, self-awareness as a therapeutic subject and improving quality of nursing. The concept was clarified through presentation of model, borderline, related, and contrary cases. Conclusion: The results of this study are meaningful in that the concept and attributes of empathy are explored in the area of nursing. Also, based on results of this study, development of standardized tools to measure patient-perceived empathy and measure the three attributes of empathy is recommended as well as the development of educational programs to enhance empathy.

In this paper, we study the distributed coordination of a set of synchronous, anonymous, memoryless mobile robots that can freely move on a two-dimensional plane but are unable to communicate directly. Based on this model, we analyze the application problem that consists in having a group of robots form a barricade line to protect from car traffic a crowd of demonstrators parading on the street. For the sake of robustness, we privilege fully decentralized solutions to the problem. In particular, we give a self-stabilizing distributed algorithm to address the problem, in this presentation

Pneumoparotid is a rare diagnosis to consider when faced with unexplained parotid swelling. It is caused by an excessive increase of intraoral pressure and reflux of air through the Stensen duct and its glandular branches. It is more likely to occur in persons who have regularly raised intraoral pressure, for example glass and balloon blowers and wind instrument players. It can also be self-induced by habitual tic. Herein, we report a rare case of pneumoparotid with initial presentation of painless swelling in left parotid region. It was caused by habitual cheek inflating and improved with conservative management.
