본 논문에서는 키넥트 센서 기반의 치매 예방을 위한 카드 뒤집기 게임을 설계하고 구현한다. 이 게임은 사용자의 기억력 향상과 두뇌 활동 촉진에 따른 치매 예방을 목표로 한다. 키넥트 센서를 활용하여 사용자의 손 움직임을 감지하고, 이를 통해 게임 내에서 마우스 포인터의 움직임과 클릭 동작을 구현한다. 게임을 진행하면서 사용자는 뇌 활동뿐만 아니라 미세한 손의 움직임을 통한 운동을 유도하여 노인층의 두뇌와 신체 활성화를 기대한다. 이 게임은 사용자에게 즐거운 게임 경험과 신체 활동을 통한 두뇌 활성화를 제공하여, 치매를 예방할 수 있도록 한다.

Today the traditional national intelligence activities which are mainly based on classified informations are confronted with several problems. These are excessive collection cost, morality of intelligence activity, objectivity of intelligence, intelligence dead zone and timeliness of intelligence etc. On the other hand, circumstances of national intelligence activity are rapidly changed. Those are rapid growth of internet, transformation of classified information into open one and rapid growth of intelligence capabilities of private sector. To cope these problems and circumstances, we reevaluated OSINT(Open Source INTelligence) which is collected from all kinds of open source informations on the internet. First, we classified OSINT into four categories corresponding to the traditional classified collection methods i.e., IMINT, SIGINT, HUMINT and MASINT. And we evaluate the value of OSINT in comparison with classified collection methods. Finally a system for national intelligence activity based on all kinds of open source intelligence on the internet is proposed, described and compared with the system of traditional national intelligence activity.

In the era of neoliberalism with high rate of youth unemployment, young college students are forced to believe that the only way to enter the job market is by accepting and participating temporary off-campus apprenticeship, which often disguised as an internship for the creative culture and knowledge. This article discusses that the mode of off-campus apprenticeship, which is supposed to voluntary and participatory, bears in fact a strong resemblance with digital labor. Based on a series of in-depth interviews with college students, this study argues that the apprentice-typed labor denotes a process by which immaterial labor or free labor coincides with self-directed job training. Throughout the digital labor processes young college students are in a constant oscillation between precarity and hope, negotiating their autonomy and social conditions in the neoliberal work environment. The digital labor accumulates students' knowledge and information as a form of commodity, which in turn supports communicative capitalism.

Multilevel and Multivariate Structural Equation Mpdel is applied to handle the hierarchical nature of the data and explain complex relationship among socioeconomic factors of individuals and household, activity participation, and travel behavior using Puset Sound Transportation Panel data. From analysis, variations of individual activity participation and travel behavior can be divided into two categories : Within-household variation and Between-households variation. Empirical results show that the interdependency index(p) of variables for household members within a household is between 0.13 and 0.33 indicating high interdependency. These results suggest that Multilevel and Multivariate SEM approach is an appropriate modeling methodology and gives additional information for activity participation and travel behavior. Also most of personal and household characteristics influence on activity participation and travel behavior within a household as well as between households.

The purpose of this study is to examine the effects of educational activities based on oriental mythology on young children's creativity and personality. A total of 14 sessions were applied to 36 children (18 experimental group and 18 control group). For this study, myths in Shan-hai jing, The Classic of Mountains and Seas), which is the origin of oriental mythology, were used as basic data of class activities and developed to experimental groups. The collected data were analyzed using SPSS 21.0 statistical program and covariance analysis (ANCOVA) was conducted with covariance score of the group after the activity. The results of this study were as follows: First, integrated educational activities using oriental mythology had a positive effect on all children's creativity and all sub-factors. Second, integrated educational activities using Oriental mythology have a positive effect on children's personality. The expansion and transformation of educational texts to oriental mythology is not only helpful for young children's creativity and personality development, but also enables them to experience cultural balance through their new understanding of the Orient.

Recently, many human activity recognition(HAR) researches using smartphone sensor data have been studied. HAR can be utilized in various fields, such as life pattern analysis, exercise measurement, and dangerous situation detection. However researches have been focused on recognition of basic human behaviors or efficient battery use. In this paper, exercising activities performed indoors and outdoors were defined and recognized. Data collection and pre-processing is performed to recognize the defined activities by SVM, random forest and gradient boosting model. In addition, the recognition result is determined based on voting class approach for accuracy and stable performance. As a result, the proposed activities were recognized with high accuracy and in particular, similar types of indoor and outdoor exercising activities were correctly classified.

As society has more interest in reading activities, it has become possible to secure social value of libraries through the promotion of reading. In this regard, the study aimed to analyze social tasks that the libraries face and suggest concrete methods through bibliographical examination. Currently, various regions of the nation have an increasing interest in libraries, particularly, children's libraries. The public libraries can expand their social roles by meeting these social requests. As a variety of activities by the public libraries to promote reading have helped people recognize the importance of libraries, more aggressive reading promotion activities are considered to help expand the roles of the public libraries and secure social base. Accordingly, the libraries need to take the initiative in implementing various measures by establishing a committee to adjust various reading promotion activities in the government and the public and private sectors, coming up with legal base, pursuing development of voluntary reading promotion programs, establishing an information network for reading and books, publishing book reviews, leading campaign for reading and reading promotion activities, supporting reading at home and expanding award system with regard to the promotion of reading.

The purpose of this study was to verify that students' interest in team activities for problem solving, the effect of interest on it, and students' changes in perceptions and their behavioral characteristics in the process of problem solving. The study reviewed documents prepared by students, such as work sheets, descriptive questionnaires, works and their photos, student activity photos and observation journals of teachers. The results of this research are as below. First, a problem solving team activity for making a model car was considered an interesting assignment by more than 90% of male/female students. The fact that female students could be more focused on this assignment than male students was discovered. Interest in the assignment not only had an influence on the points from the start (the blueprint) to the end (model cars completed based upon the designs) of problem solving, but also provided the traction power behind the assignment. Second, the problem solving team activity allowed the students to change their existing recognition (thoughts) while positively taking a lead or indirectly utilizing various learning experiences (including experiences of failure). Third, $2^{nd}$ graders in middle school had a tendency to solve problems in dependently rather than to receive help from others when they encountered problematic situations.
