Objectives : The special class has been made, bringing rapid increase quantitatively. The authors carried out the child psychiatric interview and evaluation for 9 special-classed children in Asan city to find out clinical diagnosis and emotional/behavioral characteristics. Methods : The child psychiatrists evaluated special class children by DSM-IV and K-SADS-PL. Tools for the evaluation were Child Behavior Checklist- Korean version, Korean Personality Inventory for Children, Children's Depression Inventory, Abbreviated Conners Parent-Teacher Rating Scale-Revised, State-Trait Anxiety Inventory for Children, Vineland Social Maturity Scale, Wechsler Intelligence Scale for Children-III, and Childhood Autism Rating Scale. Results : Ultimately 53 children, consisting of 35 boys(67.9%) and 18 girls(32.1%), participated, and the average age was $10.5{\pm}1.3$ years old. Their measure of Vineland Social Maturity Scale was $78.7{\pm}20.0$, Childhood Autism Rating Scales was $25.4{\pm}9.0$, Child Depression Inventory was $22.2{\pm}5.2$, State-Trait Anxiety Inventory for Children was $35.2{\pm}8.2/36.5{\pm}6.2$, and Abbreviated Conners Parent-Teacher Rating Scale was $11.0{\pm}4.6$. In the clinical diagnosis evaluation, the prevalence rate of learning disorder was decreased compared to early research, ADHD had been newly appeared and depression disorder and anxiety disorder had been increased. Conclusion : This result suggests that a lot of children in a special class have complex emotional and behavioral problems in addition to educational problems.

Recently, public interest in virtual reality (VR) and augmented reality (AR) has increased. Therefore, computer graphics-related research has been actively conducted. This has included research on virtual space related to human posture implementation. However, such research has focused on general posture in humans. This paper presents a system with reference to the basic posture in sports climbing and the inverse kinematics method for generating the positions and behavior of virtual characteristics in a three-dimensional virtual space. The simulation based on the inverse kinematics method, produced with an inverse kinematics solver and initial pose animation from motion capture, provides realistic and natural movement. We designed a simulation system to generate correct posture and motions similar to those in sports climbing by applying the basic procedure of sports climbing. The simulation system provides help for producing content about sports climbing, such as learning programs for novice climbers and sports climbing games.

Objectives: We describe the development of a smoking and drinking prevention program for adolescents, using intervention mapping. Methods: The study sample consisted of 1,000 high school second-grade students from 6 high schools in Seoul. The PRECEDE model was applied for the needs assessment. We carried out a social diagnosis by assessing the factors such as the quality of life, happiness level, and satisfaction with school life; an epidemiological diagnosis on the perceived health status, stress levels, and priority of health issues; a behavioral diagnosis on the smoking and drinking rate and the intention to smoke and drink; and an educational diagnosis on knowledge, beliefs, attitudes, self-efficacy, outcome expectations, social norms and life skills. Results: The development process included a needs assessment, identifying factors that influence smoking and drinking among adolescents. Intention, knowledge, perceived norms, perceived benefit, perceived cost, perceived susceptibility, self-efficacy, and life skills were identified as determinants. Three performance objectives were formulated to describe what an individual needs to do in order to avoid smoking and drinking. Subsequently, we constructed an intervention matrix by crossing the performance objectives with the selected determinants. Each cell describes the learning objectives of the smoking and drinking prevention program. The program used methods from the transtheoretical model, such as consciousness raising, outcome expectations, self-reevaluation, self-liberation, counterconditioning, environmental reevaluation, and stimulus control. The program deals with the effects of smoking and drinking, self-improvement, decision making, understanding advertisements, communication skills, social relationships, and assertiveness. Conclusions: By using the process of intervention mapping, the program developer was able to ensure a systematical incorporation of empirical and new data and theories to guide the intervention design. Programs targeting other health-related behavior and other methods or strategies can also be developed using this intervention mapping process.

Images have been substantially searched and used due to not only the advanced internet and digital technologies but the characteristics of a younger generation. The purpose of this study aims to discuss the ways on expanding the access points to images by analyzing the needs of users in context of everyday life. In order to achieve the purpose of this study, 105 questions of image seeking in NAVER, which is one of social Q&A services in Korea, were analyzed. For the analysis, a two-dimensional framework with image uses and image attributes were utilized. The findings of this study demonstrate that considerable use purposes on data oriented pole, such as information processing, information dissemination and learning are identified. On the other hand, image attributes from the needs of image show that non-visual aspects including contextual attributes are recognized substantially in addition to the traditional semantic attributes.

The purpose of this study is to develop a prediction model of hypertension in middle-aged adults using Statistical analysis. Statistical analysis and prediction models were developed using the National Health and Nutrition Survey (2013-2016).Binary logistic regression analysis showed statistically significant risk factors for hypertension, and a predictive model was developed using logistic regression and the Naive Bayes algorithm using Wrapper approach technique. In the statistical analysis, WHtR(p<0.0001, OR = 2.0242) in men and AGE (p<0.0001, OR = 3.9185) in women were the most related factors to hypertension. In the performance evaluation of the prediction model, the logistic regression model showed the best predictive power in men (AUC = 0.782) and women (AUC = 0.858). Our findings provide important information for developing large-scale screening tools for hypertension and can be used as the basis for hypertension research.

As the advances of technology in mobile networking and the popularity of online social networks (OSNs), the mobile social networks (MSNs) provide opportunities for marketing strategy. Therefore, understanding the information diffusion in the emerging MSNs is a critical issue. The information diffusion address a problem of how to find the proper initial nodes who can effectively propagate as widely as possible in the minimum amount of time. We propose a new diffusion scheme, called Hotspot DBC, which is to find k influential nodes considering each node's mobility behavior in the hotspot zones. Our experiments were conducted in the Opportunistic Network Environment (ONE) using real GPS trace, to show that the proposed scheme results. In addition, we demonstrate that our proposed scheme outperforms other existing algorithms.

Inspired by the social behavior models of a bird flock or fish school, particle swarm optimization (PSO) is a popular metaheuristic optimization algorithm and has been widely used from solving a complex optimization problem to learning a artificial neural network. However, PSO is difficult to apply to many real-life optimization problems involving stochastic noise, since it is originated in a deterministic environment. To resolve this problem, this paper incorporates a resampling method called the uncertainty evaluation (UE) method into PSO. The UE method allows the particles to converge on the accurate optimal solution quickly in a noisy environment by selecting the particles' global best position correctly, one of the significant factors in the performance of PSO. The results of comparative experiments on several benchmark problems demonstrated the improved performance of the propose algorithm compared to the existing studies. In addition, the results of the case study emphasize the necessity of this work. The proposed algorithm is expected to be effectively applied to optimize complex systems through digital twins in the fourth industrial revolution.

The purpose of this study was to analyze the influence of self-leadership of Korean aircraft mechanics on organizational effectiveness and to investigate whether safety culture has mediating effect. The theory of leadership, which has emerged since the 1940s, has been an important and key research issue in the social sciences for the last decade and has evolved as a brand-new theory through the theory of characteristics, the theory of behavior, and the theory of situation. The new leadership theory has been extended to charismatic leadership, transformative leadership, empowerment leadership, super leadership, and self-leadership of organizational members as a new flow leadership. On the other hand, there was a precedent study on the relationship between leadership and safety culture, and this study started with interest in the relationship between self-leadership, safety culture and organizational effectiveness. As a result, safety culture has been proved to play an moderating variable in the relationship between self-leadership of Korean aircraft mechanics and organizational effectiveness. Especially, among the sub-factors of the self-leadership, self-goal setting, self-reward, and natural reward have been shown to affect organizational effectiveness in combination with the sub-factors of the safety culture, learning culture and flexible culture.
