최근 강도, 성폭력과 같은 중범죄들의 수위가 높아짐에 따라 범죄 예측 및 예방에 대한 중요성이 강조되고 있다. 정확한 범죄예측을 위해서는 과거 범죄기록 데이터를 기반으로 정확도 높은 범죄분류모델을 만드는 작업이 필요하며, 신속한 범죄 대응을 위한 시스템 인터페이스가 요구된다. 그러나 기존의 범죄 요소 분석 연구는 데이터 전처리에 대한 난해함으로 인해 정확도 측면에서 한계를 보이며, 범죄 모니터링 시스템은 방대한 양의 범죄 사건기록 분석 결과를 단순 제공함으로써 사용자에게 효과적인 모니터링 기능을 제공하지 못하고 있다. 따라서 본 연구는 실시간 범죄 예측을 위한 랜덤 포레스트 알고리즘 기반의 범죄 유형 분류모델 및 시스템 인터페이스 디자인 요소를 제안한다. 실험을 통해 본 연구는 제안하는 모델이 단순히 범죄기록 데이터만으로 범죄유형을 분류하는 모델 보다 우수함을 입증하였고, 기존의 범죄 모니터링 시스템 분석을 통해 실시간 범죄 모니터링을 위한 시스템 인터페이스를 설계 및 구현하였다.

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.

General concern over 'Quality of Life(QOL)' has caused many researches, which compare nations' or cities' QOL by the normative criteria proposed by themselves. The fact that these are characterized by subjectiveness makes this study have a purpose of trying to enhance the intersubjectiveness by means of quantitive analysis to find the factors on the QOL. This study uses statistical methods such as multiple regression and factor analysis based on the secondary data from the "2011 Seoul Survey". The survey includes many items, for example happiness index and satisfaction for work, amenity, etc.. And the analysis tells three findings as follows; Firstly, five subcategories of happiness have relative importance in the order of (1)financial condition, (2)health, (3)social activities, (4)community relationship and (5)family life. These generally constitute the first factor extracted by factor analysis and named 'abundance-family-intimacy factor.' Secondly, the 'abundance-family-intimacy factor' and the 'information-danger factor' among five factors(the others are 'learning-giving factor', 'local patriotism-hope for rise factor' and 'amenity-comfort factor') have statistically significant effect to QOL. Thirdly, the first factor has positive effect, but the second has negative to QOL. Note is needed to the fact that the items on SNS and internet belong to second factor and to the result that these make QOL deteriorate. These results should be considered as having limited meaning of statistical aspect. But accumulation of following studies by quantitive approach is anticipate to make more practical and general meaning.

Cycling that transform human energy into mechanical energy is one of the man-machine systems out of sports fields. Benchmarking means " improving ourselves by learning from others ", therefore benchmarking toward dominant cyclist is necessary on field. the goals of this study were to provide important factors on multi-disciplines (kinematics, physiology, power, psychology) for a tailored-training program that is suitable to individual characteristics. Two cyclist participated in this study and gave consent to the experimental procedure. one was dominant cyclist (years:21 yrs, height:177 cm, mass:70 kg), and the other was non-dominant cyclist(years:21, height:176, mass:70). Kinematic data were recorded using six infrared cameras (240Hz) and QTM (software). Physiological data (VO2max, AT) were acquired according to graded exercising test with cycle ergometer and power with Wingate test used by Bar-Or et. al ( 1977) and to evaluate muscle function with Cybex. Psychological data were collected with competitive state anxiety inventory (CSAI-2) that were devised by Martens et. al (1990) and with athletes' self-management questionnaire (ASMQ) of Huh (2003). It appears that the dominant's CV(coefficient of variability) was higher than non-dominant's CV in Sports Biomechanics domain, that the dominant's values for all factors ware higher than non-dominant's values in physical, and physiological domain, and their values between cognitive anxiety and somatic anxiety were contrary to each other in psychology. Further research on multi-disciplines may lead to the development of tailored-optimal training programs applicable with key factors to enhance athletic performance by means of research including athlete, coach and parents.

본 논문은 사람의 언어를 발성하는 개의 사례를 수동성, 능동성으로 구분하여 음원특징과 발성 원인 등을 연구하였다. 사람의 말을 발성하는 기존 사례들을 분석한 결과, 일부 개는 주인 음성의 음향특성을 이해하고 그것을 자신의 발성기관을 통해 일시적인 소리모방이 가능하다. 이것은 언어적 소통의 기능이 없는 수동적 발성 사례이다. 반면 최근 보고된 /엄마/, /누나야/ 발성을 하는 개는 기존 사례들과 확연히 구별되는 특징을 보인다. 해당 개는 상황에 따라 해당 단어를 능동적으로 반복 발성하며, 주인과 기초적 소통과 교감 기능을 수행한다. 개가 사람의 말을 능동적으로 발성할 수 있는 이유는 두뇌가 우수하고 주인과의 친밀도가 매우 높은 점, 해당 발음에 따른 사람들의 적극적인 반응 등이 원인으로 판단된다. 해당 결과는 동물의 발성 가능 소리와, 언어 학습 가능성 연구에 활용될 수 있다.

Objectives: We reviewed digital epidemiological studies to characterize how researchers are using digital data by topic domain, study purpose, data source, and analytic method. Methods: We reviewed research articles published within the last decade that used digital data to answer epidemiological research questions. Data were abstracted from these articles using a data collection tool that we developed. Finally, we summarized the characteristics of the digital epidemiological studies. Results: We identified six main topic domains: infectious diseases (58.7%), non-communicable diseases (29.4%), mental health and substance use (8.3%), general population behavior (4.6%), environmental, dietary, and lifestyle (4.6%), and vital status (0.9%). We identified four categories for the study purpose: description (22.9%), exploration (34.9%), explanation (27.5%), and prediction and control (14.7%). We identified eight categories for the data sources: web search query (52.3%), social media posts (31.2%), web portal posts (11.9%), webpage access logs (7.3%), images (7.3%), mobile phone network data (1.8%), global positioning system data (1.8%), and others (2.8%). Of these, 50.5% used correlation analyses, 41.3% regression analyses, 25.6% machine learning, and 19.3% descriptive analyses. Conclusions: Digital data collected for non-epidemiological purposes are being used to study health phenomena in a variety of topic domains. Digital epidemiology requires access to large datasets and advanced analytics. Ensuring open access is clearly at odds with the desire to have as little personal data as possible in these large datasets to protect privacy. Establishment of data cooperatives with restricted access may be a solution to this dilemma.

This study aims to explore the casual relation between construction company employees' Self-Leadership and two variables: Organization Citizenship Behaviour and Organizational Trust through Psychology Empowerment. To explain in details, this study examines how the independent variable, Self Leadership, with its behavior-focused, natural reward and constructive thought pattern strategies, affects the dependent variable, Organization Citizenship Behavior and Organizational Trust through the intervening variable, Psychology Empowerment. A survey was conducted on current employees of construction companies in metropolitan areas to empirically examine the research model. The result of study hypothesis on Self-Leadership is as follows; first, Self-Leadership showed a positive effect on Psychology Empowerment, Organization Citizenship Behaviour and Organizational Trust. Second, Psychology Empowerment showed a positive effect on Organization Citizenship Behaviour. Third, Psychology Empowerment showed a positive effect on Organizational Trust. The capacity of individuals is critical when it comes to competitiveness of construction companies. When employees willingly participate in building trust within the company, the work place will become more and more constructive; based on trust, efficiency will increase because people from different processes can work together and performance will also improve even when project managers are absent because others could help their role instead, thus driving more efficient human resource management to the company. To conclude, a company's vision can be spread wide and far when their employees engage themselves in Learning Organization with Self Leadership. They will also be satisfied with their work through improving interpersonal relationship at work.
