Digital accessibility of the middle-aged and elderly has been increasing at a faster pace than other groups such as the handicapped and adolescents. However, studies related to the digital accessibility of middle and older adults are scarce. In order to examine variables affecting accessibility to digital information of the middle-aged and elderly people, this study researches the impacts of sociodemographic, physical and mental health and social activity variables on the accessibility of digital information. We analyzed data of 1,661 people between the ages of 55 and 84 from the 2018 Status Survey on Digital Divide conducted by the National Information Society Agency. The hierarchical multiple regression analysis shows the higher education, economic, and life satisfaction levels are, the higher digital accessibility levels of both male and female are. The result of the analysis also shows that the aged male has a higher accessibility level when he does not live alone; meanwhile, the aged female has higher digital capability as her age is lower, which describes that there are differences between gender. We expect the result of this study to be used as an important reference to understand factors related to digital accessibility level and active intervention for improving digital accessibility of the middle-aged and elderly male and female.

Although there are many research studies on the effectiveness of heat and cold therapy for patients with arthritis at home or health care center, little attention has been paid to determining which therapy associates with season is effective for patients with chronic arthritis. The purpose of this study was to explore the effectiveness of heat and cold therapy associated with season for patients with arthritis. An experimental design using replications with intervention was employed. A total of 27 female arthritic patients were selected. Data were collected in summer and winter. Hot bag and ice bag were applied on each patient's knee for each 20 minutes alternatively. Joint pain, discomfort and range of motion were measured. Data were analyzed using paired t-test, and two-way ANOVA. The results of this study were ; 1. Joint pain Heat therapy was effective for pain relief, as compared with cold therapy. Heat therapy was more effective for pain relief in winter than in summer. Cold therapy was effective for pain relief, but there was no statistically significant difference of pain relief between summer and winter. 2. Discomfort Discomfort was decreased using heat therapy, whereas it was increased using cold therapy. Although discomfort was decreased using heat therapy in both summer and winter, there was no statistically significant difference of discomfort between summer and winter. Using cold therapy, discomfort was decreased in summer, but increased in winter. and season had effect on discomfort. 3. Range of motion Although there was no statistically significant difference between the range of motion for both heat and cold therapy, range of motion was Increased using both heat and cold therapy. In winter, range of motion was increased rather than in summer by using heat therapy. Using cold therapy, The range of motion was decreased in both summer and winter. There was no stastistically significant difference of range of motion between heat therapy and cold therapy. Furthermore, there was no statistically significant difference of range of motion between summer and winter. In conclusion, both heat and cold therapy were effective for pain relief, discomfort, and range of motion, especially heat therapy. Heat therapy was effective for pain relief, discomfort, and range of motion in winter, as compared with summer. Cold therapy, however, was effective for only pain relief in winter, The findings suggest the use of heat therapy for patients with arthritis especially in winter.

Ursolic acid (UA) supplementation was previously shown to improve skeletal muscle function in resistance-trained men. This study aimed to determine, using the same experimental paradigm, whether UA also has beneficial effects on exercise-induced skeletal muscle damage markers including the levels of cortisol, B-type natriuretic peptide (BNP), myoglobin, creatine kinase (CK), creatine kinase-myocardial band (CK-MB), and lactate dehydrogenase (LDH) in resistance-trained men. Sixteen healthy participants were randomly assigned to resistance training (RT) or RT+UA groups (n=8 per group). Participants were trained according to the RT program (60~80% of 1 repetition, 6 times/week), and the UA group was additionally given UA supplementation (450 mg/day) for 8 weeks. Blood samples were obtained before and after intervention, and cortisol, BNP, myoglobin, CK, CK-MB, and LDH levels were analyzed. Subjects who underwent RT alone showed no significant change in body composition and markers of skeletal muscle damage, whereas RT+UA group showed slightly decreased body weight and body fat percentage and slightly increased lean body mass, but without statistical significance. In addition, UA supplementation significantly decreased the BNP, CK, CK-MB, and LDH levels (p<0.05). In conclusion, UA supplementation alleviates increased skeletal muscle damage markers after RT. This finding provides evidence for a potential new therapy for resistance-trained men.

The purpose of this study was to perform a content analysis on 62 domestic and international journals from 1998 to 2017, in order to review research trends in music and people with visual impairments. The framework of the content analysis was based on the year of publication, field of journal, research method, type of research, research subject, participants' age, and factors of impairment. The results showed that both domestic and international journals have rapidly increased in the last 10 years, and have expanded into the fields of education and therapy. In the research method, survey research was conducted much more frequently in domestic journals, while both qualitative and experimental research were employed on a roughly even basis in international journals. With respect to the type and subject of research, music perception and recent trends on the subject of musical interest and aptitude took up the majority of domestic journals, while international journals focused on music intervention, music perception and cognition with musical influences and experiences. The participants in both domestic and international journals were children, adolescents and adults, while the elderly were not observed. In the factors of impairment, research on people with total blindness or low vision were conducted frequently, but those with adventitious vision loss or multiple impairments were rarely performed. This study could be meaningful to suggest the direction of further studies, through the investigation of research trends in music and people with visual impairments.

As a part of host factors of dental caries, saliva has been well known for its important role in relation to dental caries. The studies on its physical and chemical characteristics on development and progress of dental caries has been conducted. Recently, various comparisons between saliva of caries-susceptable individuals and caries-free individuals has been done and the efforts to understand the mechanisms of salivary intervention of development and progress of dental caries is actively in progress. In this study, 15 children with rampant dental caries and 15 caries free children without any systemic diseases from the ages of 2 to 5 were chosen for the experiment and the whole saliva and parotid saliva from each individuals were collected and protein compositions were compared using polyacrylamide gel electrophoresis (PAGE). As results of this study, in parotid saliva, there was no difference in protein compositions between the rampant dental caries and the caries free children. While electrophoresis was done with the whole saliva, protein with 120 KDa was found in children with rampant dental caries. However, this protein was not found or unclear, if any for the caries free group. (Exceptionally, clear protein band was present for one person.) Protein compositions of whole saliva of rampant dental caries group was compared before and after the caries control and thick and clear protein bands of about 120 KDa were found in both cases. Protein compostions of caries free children and adults were identical. Quantitative analysis of protein was done for the rampant dental caries group and the control group and no significant difference was found. Taken all together, protein with molecular weight of 120 KDa, found in rampant dental caries group, was still present when the treatment for the dental caries was done so it can be assumed that this protein has no interrelation with the presence of active carious lesions during saliva collecting. It can also be presumed that this specific salivary protein with the molecular weight of 120 KDa found in rampant dental caries group has effect on development and progress of dental caries. Identification on this protein with the molecular-weight of 120 KDa and the role of this protein against dental caries remain to be solved.

By comparing and analyzing the September 11 terror attack news reports on the daily papers in the U.S., Korea, and China, this research found that national ideology and international relationship concerned have affected news report frames about international dispute matters. Both quantitative and qualitative researches identify differences in news framing. For example, after the September 11 terror attack, the most pages of the USs The New York Times and Korean Chosunilbo were covered with related articles(382 and 192 reports, respectively), whereas Chinese Inminilbo cur down to only 32 reports about the issue. Also in content, both The New York Times and Chosunilbo viewed the September 11 terror attack as evil acts which threatened world peace and justified military action against Afghanistan as inevitable revenge and justice for such evil acts, in the point of the USs official view. However, Inminilbo gave out news only based on facts in a neutral viewpoint. Moreover, regarding American military intervention, the Chinese newspapers held very different news frame from the other two by describing considerable sacrifice and pain of innocent people of Afghanistan seriously. For the story composition, daily newspapers in all three countries took the same way to report focusing on specific events with episodes.

While many social work studies has focused on the development of practice intervention and demonstration of the efficacy, little attention has been given to the way how the results can be disseminated and utilized in practice area. But attempts to bridge the research-practice gap empathize importance of dissemination and utilization including knowledge utilization, innovation diffusion, information dissemination, program replication, and technology transfer etc. In this recognition, this study that focused on the process after development of program tried to search and analyze the real disseminating process and utilization state with applying Growing-up Skills Program(GUSP) developed and disseminated by this researcher. For the purpose, theories and models for program diffusion were reviewed, and dissemination & utilization of GUSP was analyzed on the 'Herie & Martin's model' with retrospective perspectives. Through this tracer study, these were confirmed or founded as problems of GUSP in disseminating process : lack of specific strategy for the dissemination ; unplanned coping due to little preparation ; and unclear and insufficient understanding of the target system in the beginning stage of dissemination. And followings are suggested for the improvement of social work program dissemination & utilization in the field: to conduct diffusion process on the basis of a proper model; to consider integrative relationship between D&D and dissemination & utilization ; to endeavor for collecting feed back from the field ; and to reinforce social work education and study related to innovation diffusion. These results showed importance of dissemination & utilization in social work and utility of GUSP despite of several limitations. More concerns of dissemination & utilization are needed for the integration of research and practice in Korean social work.

Fistula between coronary artery and pulmonary artery is a type of coronary artery anomalies. It can cause atypical chest pain and fatigue, angina pectoris, endocarditis, finally myocardial steal can result in heart failure and myocardial infarction. But only 0.1-0.2% of coronary angiographic studies reveal the communications between coronary artery and other spaces. (heart chamber, pulmonary artery etc.) It is frequently congenital, but acquired types are increasing because chest and heart manipulations such as opertion of tetralogy of Fallot, endomyocardial biopsy, radiation therapy, or penetrating blunt trauma are increasing. There are reports about repair of fistula using thrombogenic tips, coil embolization and surgical intervention. We report a connection between coronary artery and pulmonary artery in 79 years old female. She was 30 pack-years smoker and suffered from dyspnea several years with chronic obstructive pulmonary disease. She presented with atypical chest pain and palpitation after admission. Electrocardiography showed ST-T wave abnormality. Emergency coronary angiography and chest CT scan revealed coronary-pulmonary artery fistula. Transcatheter embolization was performed and she was relieved from discomforts.

Objectives : This study was aimed at investigating the relationship between internet game addiction and emotional and behavioral characteristics of students both in the 5th and 6th grade of elementary school and in middle school. Methods : Two elementary schools and two middle schools were chosen to participate. The students completed selfreport questionnaires designed by the authors, called the Internet Game Addiction Scale, Korean youth self-report (K-YSR). Results : Compared to previous studies, the rates of those in the obvious game addiction group were much lower in this study. We defined the upper 10% of internet game addiction scores as a high risk user group and the lower 10% as a control group. There were significant differences between the groups with respect to the the ages at which internet gaming began, the frequency of game play per week, and the average length of each game playing session. Significant associations were also found between the level of internet game addiction and the withdrawn and delinquency subscales of the K-YSR. However, the association between game addiction and the withdrawn subscale was found only in middle school students. Conclusion : The findings from this study suggested that withdrawn and delinquent behaviors could be predictors of internet game addiction. Results also suggested the importance of early childhood intervention for preventing the development of more severe psychopathology in early adolescence.
