Companies widely use survey to identify customer requirements, but the survey has some problems. First of all, the response is passive due to pre-designed questionnaire by companies which are the surveyor. Second, the surveyor needs to have good preliminary knowledge to improve the quality of the survey. On the other hand, text mining is an excellent way to compensate for the limitations of surveys. Recently, the importance of online review is steadily grown, and the enormous amount of text data has increased as Internet usage higher. Also, a technique to extract high-quality information from text data called Text Mining is improving. However, previous studies tend to focus on improving the accuracy of individual analytics techniques. This study proposes the methodology by combining several text mining techniques and has mainly three contributions. Firstly, able to extract information from text data without a preliminary design of the surveyor. Secondly, no need for prior knowledge to extract information. Lastly, this method provides quantitative sentiment score that can be used in decision-making.

Purpose: Adolescence is a developmental period characterized by the rapid growth of the musculoskeletal system, which is important for maintaining correct posture. Incorrect posture, lack of exercise, and reduced physical activity can cause spine deformities and affect lifelong health. This study was designed to evaluate the application and effect of a program for improving adolescents' musculoskeletal health. Methods: A quasi-experimental pilot study was conducted with 13 male and 20 female middle and high school students, with an average age of 15.39 years. Their general characteristics and physical measurements were obtained. The program consisted of group exercises (60 minutes, once per week), gait pattern monitoring, and online communication. A paired t-test and Wilcoxon signed-rank test were used to examine the program's effect. Results: Overall posture habits improved, and the total musculoskeletal index decreased; however, these results were not statistically significant. Conclusions: The devised program was effective in improving musculoskeletal imbalance. Therefore, effective programs and health devices should be developed to help adolescents maintain correct posture and encourage and support continuous participation in such programs.

Purpose: The purpose of this study was to find out the personal characteristics of physical therapists, dementia awareness and dementia attitude, and to find out what relationship is there between personal characteristics and dementia awareness and dementia attitude. Methods: Participants in this study surveyed physical therapists who are members of the Association of Korean Physical Therapists on their awareness of dementia, and conducted online surveys from January 28 to February 27, 2021. The survey questions used in the survey consisted of 29 questions in total, including 9 general characteristics of the participant, 10 questions on perception of dementia, and 10 attitudes toward dementia. All 104 participants were surveyed, and 100 surveys were analyzed, excluding 4 surveys with insufficient responses. Results: In this study, the correct answer rate for all items in the dementia awareness sub-item was 65%, and the dementia attitude-related sub-items were generally positive. However, there was no significant correlation between personal characteristics such as gender, age, educational background, treatment target, treatment experience and dementia awareness, and no correlation with dementia attitude was significant. Conclusion: Regardless of personal characteristics such as gender, age, treatment target, and treatment experience, a positive attitude and correct recognition of dementia can improve the quality of treatment with dementia patients and increase the reliability of patients and caregivers.

온라인 서비스에서 사용자 인증은 정확하고 안전한 서비스를 위해 꼭 필요하다. 이러한 사용자 인증을 위해 OTP(One Time Password)가 많이 활용된다. OTP는 일회성이라는 특성을 만족시키기 위해 분실 및 망실의 위험이 있는 OTP 발생기나 보안카드 등을 사용하여 OTP 생성을 위한 연계 정보를 발생시키거나 최종 OTP 값을 생성한다. 본 논문에서는 u-Health care 시스템에서 수집되는 건강정보를 이용하여 OTP 발생기와 보안카드를 사용하지 않는 OTP 생성방식을 제안한다. 제안하는 방식은 웨어러블 기기를 통해 수집한 건강강보를 OTP 생성에서 사용하는 연계정보로 활용하는 방식이다. 제안하는 방식으로 생성한 OTP는 같은 인증번호가 얼마나 자주 생성되는지를 확인하는 충돌내성 실험에서 기존의 OTP 생성방식과 비슷한 결과를 나타내어 다양한 온라인 서비스에서 사용될 수 있을 것으로 판단된다.
