Social network services are developed which is based on interaction and collaboration between users. This used to teaching-learning and integrate personal experience based on constructivism and social learning has developed into. In order to use which better to support the N-Screen communication model is needed. Communication model is to support the interaction between learner-instructor- the system. However, until now, There are a lot of web-based communications research. In this study, Social Learning Services environment to extended to N-Screen. For seamless service, Location information of individuals to use to learning activities. To support this, the communication manager is to design and implement. Communications manager for the N-Screen services draw students use cases and define the required functions. Based on this, Communication function is designed. In addition, Considering the characteristics of each device, personal location information to be reflected.

The purpose of this paper is to examine some effects of four menu types: icon menu, context menu, pulldown menu, and bar selection menu. In order to find whether there are some effects of menu types or learning stages (the first, intermediate and the last stage) on skill-based errors, each of the menus has been studied in relation to hyperemia instruction, menu search time, scholastic a chievements and learners' metacognitionon their errors. A further purpose of this paper is to suggest some strategies for enabling learner to select menus more efficiently in order to enhance the learner's own learning effectiveness in hypere mia instruction.The results of this study are as follows. The menu types had a significant effect on the low metacognition regulation group. The context menu types had a significant effect on achievements. In contrast, it was also noticed he the menu types did not have any significant effect on the high metacognition regulation group. The bar-selection menu type and the icon menu type had a relatively significant effect on skill-based errors in the first stage of learning.

Smart Jewelry is applied to the components of the Internet of Things. The process of obtaining the status information to the input of the sensor. And it controls the light color of the LED. Because to express the beauty of twinkling lights that can be felt in the jewelery and aesthetic functions were applied in order to feel the mystery. Smart Jewelry is capable of communication, interaction, wearable. Smart jewelery was equipped with a color, temperature, ambient light sensor. It was designed to allow interaction with a Bluetooth module. Applying an algorithm so that the light jewelry colors can vary depending on the circumstances of the smart jewelry wearer had been implemented by the mobile application. It can be realized in digital technology and the convergence of life. It presents the orientation development of the smart jewelery device on IoT environment.

본 논문에서는 실제 카메라 영상으로 획득하기 어려운 화재, 살인 등의 뉴스 사건을 시청자들에게 효과적으로 전달하기 위해서 다수의 가상캐릭터가 등장하는 애니메이션을 신속, 편리하게 제작할 수 있는 사건 재연 시스템의 개발 기법을 소개한다. 본 시스템은 미리 구축된 동작 및 모델 라이브러리를 이용하여 다수의 가상캐릭터 움직임을 제어함으로써 고가의 동작 포착 장비와 연기자가 없어도 신속한 가상캐릭터 애니메이션 제작이 가능하다. 사건 재연 시스템의 가상 캐릭터 동작 제어는 동작 지정, 동작 생성, 동작 편집의 세 단계로 구성된다. 동작 지정 단계에서는 사건 시나리오에 따라 모델 라이브러리부터 가상캐릭터와배경 모델을 선택하고, 동작 라이브러리부터 가상캐릭터의 동작을 선택한다. 동작 생성 단계에서는 지정된 특정 사건을 기술하는 동작에 이동 동작을 연결함으로써 가상캐릭터의 부드러운 동작을 생성한다. 동작편집 단계에서는 가상캐릭터 사이의 상호 작용 또는 가상캐릭터와 가상환경의 상호작용을 보다 정확하게 제어하기 위해서 특정한 시간에서의 가상캐릭터 위치와 자세 등을 조정한다. 본 시스템은 편리한 사용을 위해 대화형과 스크립트 기반의 인터페이스를 적용하였으며, 3차원 그래픽 소프트웨어인 Maya의 플러그인(Plug-in) 소프트웨어 형태로 개발하여 Maya의 고성능 그래픽 기능을 활용하였다.

The purpose of this study was to investigate the effects of 12-week aquarobics exercise on blood lipids, atherogenic index, and liver functions in elderly women. The subjects for the study were 25 healthy elderly women volunteers, aged 65 to 80 years, composed of the aquarobics exercise group (n=13) and control group (n=12). Twice a week for 60 minutes for 12 weeks. The exercise intensity was set to RPE 11-12 for 1 week to 4 weeks, RPE 13-14 for 5 week to 8 weeks and RPE 15-16 for 9 week to 12 weeks respectively. The test data were analyzed by two-way repeated measures ANOVA, paired t-test, and independent t-test. The alpha level of .05 was set for all tests of significance. The results of the study in the aquarobics exercise group were as follows; LDL-C (p<.05), AST (p<.05) had significantly decreased, with TC (p<.01), TG (p<.05), LDL-C (p<.05), LDL-C/HDL-C (p<.05), TG/HDL-C (p<.05), AST (p<.001) significantly lower than control group. Consequently, these findings suggest that regular aquarobics exercise will be effective for preventiy the metabolic syndrome and cardiovascular health in elderly women.

In this study, we tried to find the moderating effect as an interaction between brand concept variables and thinking style variables as well as the main effect of each. To this end, the inner wear bradns, CalvinKlein(symbolic concepts) and bodyguard(functional concept), as two parent brands and wallets as an extension product were selected. The results of this study were as follows: (i) Extension evaluation as well as fit judgement based on brand concepts was higher in symbolic brand than functional brand. (ii) The holistic thinkers were higher in fit judgement and expansion evaluation than the analytic ones. (iii) In case of symbolic brand, there was little differences in fit judgement and expansion evaluation between holistic thinkers and analytic thinkers. But In functional brand, there was some differences relatively. So, we found the interaction effect between variables in fit judgement and expansion evaluation. We can expect this research result to be helpful in working out diverse and practical marketing strategies using existing brand concepts in the global market environments.

The CNV (Copy Number Variation) which is one of the genetic structural variations in human genome is closely related with the function of gene. In particular, the genome-wide association studies for genetic diseased persons have been researched. However, there have been few studies which infer the genetic function of CNV with normal human. In this paper, we propose the analysis method to reveal the functional relationship between common CNV and genes without considering their genomic loci. To achieve that, we propose the data integration method for heterogeneity biological data and novel measurement which can calculate the correlation between common CNV and genes. To verify the significance of proposed method, we has experimented several verification tests with GO database. The result showed that the novel measurement had enough significance compared with random test and the proposed method could systematically produce the candidates of genetic function which have strong correlation with common CNV.

Rapid development of electronic technology has made it possible to perform various function. But this technology made it increase it's complexity. Therefore, It was important to identify usability problem in interface design. The quality of interface to promote the efficient interaction should be evaluated with regard to users' cognitive characteristics. So, in this paper, washing machine, that is one of the most useful electronic home application was studied menu structure on interface and it's operational states transition. At first, an cognitive menu structure is identified with users' conceptual similarity of the main function of washing machine. Then three washing machines was selected to compare with the cognitive menu structure. And, we were analyzed how operational state of the washing machine was transfered. As a result, we can be revealed that menu operational method based on the cognitive structure was consistent with the user's preferred operational method during the experimental tasks and the users and designers had a different knowledge of an it's function structure. These results will be useful to design the washing machine interface.
