This study has developed a preventive launcher from smartphone addiction for the digital generation and the contents recommendation based on machine learning which used multiple and collective intelligence. This could provide convenient digital nurturing experience for the parents who fear their children's over use of digital devices and also suggest individually adaptive digital learning methods that enhance the learning efficiency and pleasurable and safe learning environment for the children. Suggested application is a kind of gamification launcher that protects children from harmful contents and from smartphone addiction with time limit settings. For parents who find difficulty choosing from various kinds of contents and applications for education, this suggested system could provide a learning analytic report based on big data after collecting and analyzing the data of their children's learning and activities and recommend contents necessary for their kids using recommended algorithm by collective intelligence.

This research is to consider the training effect of effective paralytic transfer method and reduce the risk of paralytic transfer. It was questioned and interviewed the guardians of 50 patients agreed this research among the guardians of patient who hospitalized in rehabilitation ward. The contents of questions was safety grade with 1~10 point which the guardians of paralytic was feeling in case transfer the patient of paralytic. The sense of safety before and after the traning of transfer method was improved about 25% more from 5.81 point to 7.26 point on the safety. The 98% of subjector supported the needs of training for transfer method of paralytic. And also 74% of subjector replied that the safety was improved after taking the training. On the base of this research, it is needed to review this kind of traning to get reliability and propriety throuth repeatitive research.

This study examines whether personal traits and globalization capability would affect the entrepreneurial intention. Survey using questionnaires was conducted toward 257 male and female adults aged 21 above across the nation. The analysis of the data shows that the desire for self-fulfillment, risk-taking propensity and sense of self-efficiency as personal traits have positive influence on entrepreneurial intention. And the globalization capability as mediating variable has meaningful influence on entrepreneurial intention, that is, globalization capability under the control of respective personal trait makes positive influence on entrepreneurial intention. Current study would support the potential entrepreneur and the educator to create effective entrepreneurial education program.

The purpose of this study was to investigate the association between masticatory ability and oral health-related quality of life using the Oral Health Impact Profile (OHIP-14) of the elderly. Total 195 elderly subjects were assessed for subjective masticatory ability, objective masticatory ability and OHIP-14 concerned with quality of life. When masticatory ability is low, the odds ratio(OR) of the quality of life is worse was increased. After adjusted age, residence, education, denture, odds ratio of subjective masticatory ability was 2.42(p<0.05) increased and odds ratio of objective masticatory ability was 7.58(p<0.001) increased. This study showed significant association between masticatory ability and the total OHIP-14 score of the quality of life of the elderly. Masticatory ability can affect quality of life oral health-related in elderly. While following up on various studies were carried out as a long-term, I hope it will be of help in improving the quality of life of the elderly with maintaining a healthy oral health.

The purpose of this study was identify the factor affecting alcohol use disorder in Korean women. This study used the data from the 6^th Korea National Health and Nutrition Examinations Survey and analyzed the demographic characteristics, health related factors and alcohol use disorder. Data were analyzed using the IBM SPSS 25.0 program. As a result, the prevalence of alcohol use disorder in Korean women was 14.7%. There were significant differences depending on age, marital status, educations level, occupation, smoking, stress, melancholy. By logistic regression, the risk factors of alcohol use disorder were age, marital status, occupation, smoking, melancholy. According to the results of this study, further research on the alcohol use disorder of single-working women should be conducted in considering of various variable.

This study was carried out to evaluate the efficacy of Virtual Reality(VR) program on recovery of functional in Stroke through systematic literature review and meta-analysis. The following databases were used to search the literature: RISS, KISS, KMbase. Keywords included 'stroke', 'CVA' 'virtual reality', 'rehabilitation', 'virtual reality program' and the evaluated articles were published from 2009 to November 2018. The statistical was used R program, the effect size of upper limb, balance and ADL were calculated by random-effects model. As a result, 9 RCT studies were meta-analyzed and were evaluated for the risk of bias by the RoB of Cochrane Collaboration; the overall risk of bias was low. The effect sizes of VR program was balance(g=.77), ADL(g=.80) as indicated by a "large effect size". Therefore, VR program is large effective in reducing balance and ADL in strokes. It is necessary to develop and apply a virtual reality-based program using more efficient program development.

Due to the development of advanced technology, a lot of digital radiographic equipment has been developed, which is very helpful for accurate diagnosis and treatment, and it is very important to train personnel who have acquired professional knowledge in order to use it safely and effectively. Students are exposed to the risk of radiation exposure in radiography training using diagnostic X-ray equipment, and some educational institutions do not use X-ray equipment due to management difficulties in accordance with the Nuclear Safety Act. As a solution to this, this study developed a medical radiation simulator for education that does not generate radiation by using a vision sensor and self-developed software. Through this, educational institutions can reduce the burden of administrative implementation according to the law, and students can obtain a high level of educational effects in a healthy practice environment without radiation exposure.

According to the National Statistical Office, the number of fires was the 42,135 items in 2014, it has increased reviews 1203 compare with 2013. In addition, the sum of the property damage 2,560 billion, injured number 1,599 people, it was announced in deaths number 263 people. Although Korea government have announced many fire manuals for fire prevention, the reason that many of the wounded and the dead occurred is because people have recognized fire riskiness in just only head simply from manual. In this paper, the simulation system for prevention of fire based virtual reality is proposed to solve this problems. The people who trained by proposed system can recognize and realize fire riskiness more than fire writing manuals.

현재 타블렛PC, 전자칠판, 디지털 키오스크 단말, 은행 ATM기기 등에서 키보드 및 버튼이 아닌 터치패널을 이용해 사용자가 더욱 직관적인 입력을 할 수 있도록 지원하고 있다. 나아가 이러한 터치패널은 하나의 접점만 인식하는 것이 아닌 현재 기술로 여러 개의 접점을 인식하는 멀티터치 방식을 채택하고 있다. 본 논문에서는 이러한 멀티터치 환경에서의 다중 입력을 통한 사용자 인증 방식에 대한 아이디어를 소개하고자 한다. 멀티터치 환경에서의 비밀 번호 입력으로 이전의 싱글터치 기반에서 1글자씩 입력되던 비밀번호가 멀티터치 기반에서는 2개 이상의 글자로 입력될 수 있다. 멀티터치 기반의 패스워드 입력은 단순히 [ 1, 2, 3, 4 ] 로 입력되던 패스워드를 [ (1,3), 2, (3,4), (1,2,3) ] 와 같은 방식으로 설정함으로써 사용자 패스워드의 암호화 강도를 높이고 패스워드 노출 위험을 줄이려 하였다. 본 연구는 나아가 멀티터치 기반에서 사용자 패스워드를 넘어 개인 인증을 위한 보안 기술 연구의 초석으로 활용 될 것이다.

The purpose of this study was to understand the dental hygienist's perception of dental materials and to understand the safety status of harmful chemicals. The study was conducted from January to February 2015 for 250 dental hygienists working in Gwangju Metropolitan City. as a result, the degree of recognition of MSDS for dental materials was higher with age (P <0.05) and higher in dental hygienist (P <0.001) working at dental hospital. (P <0.001), and the factors affecting the perception of first aid treatment were positively correlated with experience of hazard education (P <0.001). Therefore, by understanding the MSDS awareness of dental materials by dental hygienists and the safety situation in the handling of hazardous chemical substances, we provide basic data for establishing proper recognition of safety in the handling of harmful chemical substances and developing educational programs to prevent accidents.
