  • Purpose: This study was conducted in order to explore self-perceived objectives, effects, determinant factors of satisfaction and demands on home-based rehabilitation service (HBRS) based on a community-based rehabilitation (CBR) model in community-dwelling disabilities. Methods: This research was conducted through in-depth interview. HBRS was conducted by four physical therapists for one hour a day, once a week, for eight weeks. After an eight-week intervention period, in-depth interviews were conducted using a semi-structured questionnaire for five recipients of HBRS and six care givers. Results: For the physical effect, some participants experienced positive effects, whereas others did not due to the short-term intervention period. For the social and emotional effects, 'occurrence of motivation for exercise', 'change of surroundings' and 'sorriness for the therapist' emerged as keywords. For the determinant factors of satisfaction, 'movement-inducing therapy', 'therapy from the specialist', 'development of friendship & social network', and 'learning the way of self-rehabilitation' emerged as keywords. For further demands on HBRS, participants stated that 'sufficient time for therapy', 'user opinion-reflected therapy', 'additional instructions for therapeutic exercise & activities of daily living', and 'active promotion for HBRS' were necessary. Conclusion: Participants were satisfied with the physical, social, emotional, and educational aspects of HBRS. In particular, the participants regarded educational aspects as the significant factor throughout self-perceived objectives, determinant factors of satisfaction and the demands. This result suggests that when providing HBRS to community-dwelling persons with disabilities, therapists should recognize the necessity and significance not only of the physical, but also the educational aspect of HBRS.

  • The purpose of this study is to test the applicability of neuro-fuzzy system for monthly dam inflow forecasts by using weather forecasting information. The neuro-fuzzy algorithm adopted in this study is the ANFIS(Adaptive neuro-fuzzy Inference System) in which neural network theory is combined with fuzzy theory. The ANFIS model can experience the difficulties in selection of a control rule by a space partition because the number of control value increases rapidly as the number of fuzzy variable increases. In an effort to overcome this drawback, this study used the subtractive clustering which is one of fuzzy clustering methods. Also, this study proposed a method for converting qualitative weather forecasting information to quantitative one. ANFIS for monthly dam inflow forecasts was tested in cases of with or without weather forecasting information. It can be seen that the model performances obtained from the use of past observed data and future weather forecasting information are much better than those from past observed data only.

  • Owing to increasing demand of rare metals present in ICT products, it is necessary to promote the rare metal recycling industry from an environmental viewpoint and to prevent climate change. Despite the fact that information for toxic substances is partly indicated, a legal basis and an international standard indicating usage of rare metals is insufficient. In order to address this issue, a newly created study group of environment and climate change at the ITU (International Telecommunication Union) is doing research to develop methodologies for recycling rare metals from ICT products in an eco-friendly way. Under this group, the Republic of Korea has established two international standards related to rare metals present in ICT products. The first is 'Release of rare metal information for ICT products (ITU-T L.1100)' and the other is 'Quantitative and qualitative analysis methods for rare metals (ITU-T L.1101)'. A new proposal for recommending the provision of rare metal information through a label by manufacturers and consumer/recycling businesses has been approved recently and is supposed to be published later in 2016. Moreover, these recommendations are also being extended to IEC, ISO and other standardization organizations and a strategy to reinforce the ability for domestic standardization is being established in accordance with industrial requirements. This will promote efficient recycling of rare metals from ICT products and will help improve the domestic supply of rare metals.

  • Problem-based learning has been considered as one of the effective educational methods in engineering education. However, in so far as professors who require practical insights in PBL and experiences of developing actual problems by subject, in particular, thorough understanding from experiences of PBL process as well as problem-development has not been sufficiently provided. The purpose of this paper is to present strategies focusing on problem design for PBL on engineering education. In order to do this, a literature review and a qualitative case study were performed. Especially, the study intended to identify differences and gap between professors' problems-development process and its output and those of authentic PBL. Professors were found that their PBL problems had lack of authenticity, consideration on experiences of students, and realistic thinking process. Professors in PBL had difficulty to link theory into real situation. In consequence, in designing a problem, we consider the followings; first, the problem should be designed based on real design process and its output. Second, the problem should be designed and implemented in all academic years for developing student's systematic and skillful thinking process. In conclusion, more supports are needed for engineering professors to extend their experiences of designing and developing actual problems that present real experience.

  • Purpose: The purpose of this study was to classify patients with chronic back pain according to the degree of their back pain, and to compare the pain dysfunction index with the qualitative changes in abdominal muscles. Therefore, we aimed to provide a basis for the treatment intervention method for patients with back pain. Methods: Twenty patients with chronic back pain were purposive sample to a group of 10 patients with a back pain index of 60 % or more and a group with less than 60 % of back pain, and the subjects who voluntarily participated in the study After receiving the letter, I conducted the research the dysfunction of back pain was measured by the Korean version of the Oswestry Disability Index (KODI), and the ultrasonic wave (Ultrasound MyLabOne, ESAOTE, Italy) And the white area index, and the abdominal muscle movement was used as the exercise instrument POWER breathe K5 (Hab direct, UK), which strengthens the respiratory muscles through threshold-muscle traction. Result: In this study, patients with chronic back pain were subjected to breathing exercises, which led to the decrease in back pain dysfunction. The ultrasonographic analysis of abdominal muscles revealed that both the white area index and muscle image density in the skeletal muscle and in the outer muscle of the abdomen gradually decreased over time. Conclusion: It is thought that introducing back pain patients to abdominal muscle reinforcement training is effective in improving the functions of the patients' muscles, thus increasing their quality of life.

  • The purpose of this paper is to analyse the essence of proportional reasoning and to analyse the contents of the textbooks according to the mathematics curriculum revised in 2007, and to seek the direction for developing the proportional reasoning in the elementary school mathematics focused the task variables. As a result of analysis, it is found out that proportional reasoning is one form of qualitative and quantitative reasoning which is related to ratio, rate, proportion and involves a sense of covariation, multiple comparison. Mathematics textbooks according to the mathematics curriculum revised in 2007 are mainly examined by the characteristics of the proportional reasoning. It is found out that some tasks related the proportional reasoning were decreased and deleted and were numerically and algorithmically approached. It should be recognized that mechanical methods, such as the cross-product algorithm, for solving proportions do not develop proportional reasoning and should be required to provide tasks in a wide range of context including visual models.

  • Recently, the Design-Build (DB) delivery method in public sector makes some argument by reason of the initial cost which is more higher than those of Design-Bid-Build (DBB). According to the results of pervious researches related to the performance evaluation of delivery method, DB can lead the reduction of project cycle time and also is superior to the traditional DBB in terms of construction quality. The performance on each delivery method could be generally evaluated by a project cost and a project cycle time as one of quantitative analyses, and also by construction quality as one of qualitative analyses. In most researches, the evaluation of performance level based on delivery methods has been evaluated by the degree of their satisfaction through the interview with owners. Therefore, this paper analyzed the design documents of construction projects delivered by traditional DBB and DB in bridge construction projects in order to measure design quality, constructability, maintainability, and etc. As an above-mentioned analyses, finally, this research shown that how much the difference of performance level is by each delivery method.

  • Purpose: The purpose of this study was to review systematically the effects of home based pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) patients using qualitative synthesis. Methods: Studies designed randomized controlled trials were identified to extract data and to assess the quality of studies in 8 domestic and 3 foreign search engines, and hand search reference reviews. Results: A total of 9 studies met the inclusion criteria. Overall, the methodological quality of the studies ranged from average to poor. Home based pulmonary rehabilitation consisted of exercise, education, and psychosocial interventions. Several exercises such as aerobic, strength, respiratory muscle training, and flexibility were used in home based pulmonary rehabilitation for COPD patients. Upper muscle exercise and walking were the most frequently used exercises. The most common topics for education were 'knowledge of the illness' and 'drug management'. Walking distance test (WDT) and quality of life (QoL) were the most frequently measured as the dependent variables to evaluate rehabilitation outcomes, followed by pulmonary function test (PFT) and dyspnea. WDT was the most effective outcome, followed by dyspnea, QoL and PFT. Conclusion: This study informed about the details of scientific and effective home based rehabilitation programs in COPD patients for future researchers and clinicians. These findings can help expand the recognition and accessibility of home based rehabilitation in COPD patients.

  • Information sharing is one of the key factors enhancing government efficiency and public convenience. However, critics argue that Korean government is now facing various kinds of barriers such as insufficient collaboration among agencies, inappropriate statutes, and technical problems. Thus, this study aims to develop policy alternatives that help resolve the existing problems suggested above. In order to achieve research objectives, this study employs both quantitative and qualitative methods as ways to investigate different dimensions of information sharing in government. Both survey and interview include six dimensions such as organization, technology, culture, management, policy and law. The results show that Korean government needs to implement following alternatives; developing its own database that helps support government decision making, changing organizational culture, continuous extension in terms of the number of object information and affiliated agency, and developing a statute dealing with government information sharing.
