Background: The aim of this study was to determine the effectiveness of self-efficacy promoting pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD). Methods: thirty six patients, with clinically stable COPD were randomly assigned: 18 to a rehabilitation group and another 18 as a control group, The subjects participated in a the self-efficacy promoting pulmonary rehabilitation program for 8 weeks. This program consisted of education, breathing retraining, exercise training, relaxation and counseling. The control group received education only. The outcome variables were self-efficacy, dyspnea, exercise endurance, pulmonary function, and quality of life. Dyspnea was measured using the modified Borg scale. Exercise endurance was measured by the six minute walking distance. The quality of life was measured by the quality of life index for pulmonary disease patients. Results: In the rehabilitation group after performing the self-efficacy promoting pulmonary rehabilitation program, the self-efficacy score, exercise endurance, and quality of life score were higher than the control group (p=0.007, p=0.038, and p=0.039, respectively). and the exertional dyspnea score was significantly lower than controls(p=0.045). However, the dyspnea score and FEV1 were similar after performing the self-efficacy promoting pulmonary rehabilitation program. Conclusion: The self-efficacy promoting pulmonary rehabilitation program is effective to in improve self-efficacy, exertional dyspnea, exercise endurance and quality of life in patients with COPD.

This study examined how students' satisfaction with their major department influences their organizational commitment and intention to pursue a career in tourism-related fields among college students majoring in hospitality and tourism. The results indicated that their overall satisfaction with their department affected positively their organizational commitment but not the behavioral intention to pursue career in the tourism-related fields. Organizational commitment, on the other hands, exerted a positively significant influence behavioral intention to pursue tourism-related career. The results of this study underscored the needs for the educators to manage students' psychological attachment to the department they belong to and their major field of study. Continuous relationship-building efforts should be made for the students to pursue tourism-related career after graduation. Such efforts include efficient communication between faculty and students, extended supports from the school and alumni to the students, and last but not the least, sufficient supports from colleges.

Saseol-sijo, a form of sijo with longer verses, still affords pleasure to modern readers, even when it is read without the original performance context. In this study, I focused on Saseol-sijo that induces laughter through exaggeration and caricature while singing about eagerly waiting for a lover who has left. These texts describe concurrently the emotions that are contradictory to each other, such as nostalgia and laughter. In addition, this feature reflects human's inner emotions that are not unified but rather change dynamically. Craving creates a sense of nostalgia, and also produces a comical element in nostalgia, so that nostalgia and laughter can be co-exist without conflict. In this study, 'semiotic square' was applied as the framework for interpreting the Saseol-sijo, which demonstrates the coexistence of inconsistent meanings. As a result, a Saseol-sijo which sings about waiting for a lover can be interpreted through contraires such as prohibition and authorization, craving and concerns, exposure and concealment and concentration and dispersion. The nostalgic laughter in Saseol-sijo is generally based on the conflict between the craving self and the restrictive world. A character consumed by craving may seem ridiculous and pathetic in the view of others. However, people in general would find sympathetic humor and identify with characters who portray their weaknesses or repeat their mistakes. After all, this is the laughter of compassion and reflection which Saseol-sijo evoke.

The purpose of this study was to compare factors causing stress in pediatric and general dentists when treating pediatric patients and to evaluate their overall occupational stress level. A total of 191 dentists participated in the online survey, consisting of 66 pediatric dentists and 125 general dentists. The questionnaire was conducted using Google Form. Both groups were stressed due to poor cooperation of patient and caregiver, uncertain prognosis of treatment, and low cost of pediatric dental treatment. The pediatric dentists felt relatively high stress due to poor cooperation from caregivers and an uncertain prognosis of treatment (p < 0.05). Overall occupational stress was high in both groups in the order of patient, time, job environment, and income-related stress, and the degrees of pediatric dentists were lower than general dentists. Among the 3 sub-factors of occupational burnout, more than 98% of both groups showed burnout in "depersonalization", and more than 69% of both groups showed burnout in "emotional exhaustion". Both groups showed a low burnout rate in "reduced sense of accomplishment" and pediatric dentists showed a higher sense of accomplishment than general dentists (p < 0.05). This study showed that both groups were under high occupational stress due to various factors, and efforts were required to relieve stress.

Filmic spaces are not only a core expressive factors that can embody both internal and external meanings of films, but also play an important role for initiating dramatic context in terms of narratives. They establish visible environment in which provocative incidents occur and characters' behaviors are induced, include characters' psychology or emotional meanings of narratives and provoke tensions through symbolic meanings and the implicit function of surface background. This paper, therefore, analyzes the film, , by focusing on the dramatic function of narrative space. This film provides insights and thoughts through deep philosophical reflection, by escaping from the convention of such a genre, through deep philosophical reflection, by escaping from the convention of such a genre, though it belongs seemingly to the crime thriller genre using Mexico's drug cartel as it main material. In the film, narrative spaces are responsible for emotions invoking dramatic tensions beyond provocative incidents and the elaborately planned and controlled mise-en-scene absorbed audiences' attention by organizing ultimate suspense. In conclusion, flow and dramatic lingering imagery of this film might be achieved by power of scenes rather than plot factors. This study thus explained the correlation between narrative spaces and dramatic immersion, by analyzing spaces appearing in and visualized construction. It is hoped that this will further extends the pattern of researches on dramatic immersion, which have been primarily focused on plots and characters.

In this study, 46 patients from a local hemodialysis center were enrolled to assess the effects of a self-motivated virtual reality (VR) exercise program on the heart rate variability and quality of life control in hemodialysis patients. The VR group (n = 23) completed a VR exercise program, where the subjects performed the exercise 40 min per session, 3 sessions per week, for 8weeks. After the exercise program, the heart rate variability and quality of life were measured. The VR group showed significant improvement in the heart rate variability and quality of life. The self-motivated VR exercise program provided both the role of supervisor as well as feedback, which is important for hemodialysis patients.Therefore, a self-motivated VR exercise program may be a useful tool for improving the psychosocial function in chronic disease patients undergoing hemodialysis.

The long-term use of indwelling urinary catheters can allow bacterial adhesion to their surfaces, followed by the catheter-associated urinary tract infection. In an attempt to minimize the bacterial adhesion, various amphiphilic polyurethanes (APUs) were synthesized as potential coating materials for urinary catheters. By varying composition of the soft segments such as PEO, PTMO, and PDMS, four different polyurethanes were synthesized. All the APU-coated urinary catheters had the smooth surfaces and showed higher hydrophilicity, compared to the commercial silicone catheters. In particular, the use of APUs with the higher PEG content significantly augmented hydrophilicity and remarkably reduced the total amount of bacteria adhering to the surface. Overall, the APUs prepared in this study provided the promising potential as coating materials for urinary catheters.

Purpose: In this paper, the changes in eyeglasses frames were investigated when the frames were exposed to artificial sweat. Methods: The changes in surface, hardness, and tensile strength of eyeglasses frames made of nickel silver, Monel, and titanium were tested after the exposure to the artificial sweat of pH 6.5, 6.0, and 5.0, during 1, 3, and 6 week(s), for each. Results: Corrosion pattern of eyeglasses frames made of nickel silver, Monel, and titanium was induced by artificial sweat, and the patterns were different from another frame materials. In proportion to the pH of artificial sweat and exposure time to artificial sweat, hardness of all frames made of three different material decreased, however, tensile strength of the three frames was not changed. Conclusions: The necessity of routine management for eyeglasses frames can be suggested since the changes in surface corrosion and hardness of eyeglasses frames induced by sweat were shown.

The College entrance examination stress syndrome is a kind of anxiety disorder. The underlying cause of this disorder is not a test anxiety itself. One's hidden inner and familial conflicts are more likely attributed to this disorder. Patient's the most common complaints are various psychosomatic symptoms but in severe cases underlying psychopathology may be activated and progress to major psychosis. In a broad sense adolescent's delinguent behavior, drug abuse, school drop-out and sucide are closely related to this syndrome. In clinical management of these patients, considering the special situation of impending examination, the therapist must access to central conflict theme in a short time without severe resistance. The authors classified this syndrome into 5 clinical subtypes ; 'the anxious group', 'the exhaustion group', 'the despair group', 'the emptyness group' and 'the boredome group'. Typical case of each subtype and it's management methods were presented briefly.
