Despite the development of information and communication technology, which has a great impact on society and culture, there is no platform that provides a systematic classification and state-of-the-art information retrieval system on the traditional culture. Therefore, this paper developed a traditional culture retrieval system capable of convergence services with systematic classification and retrieval based on automatically generate and visualize the 3D timeline. This system provides the function of collecting traditional culture contents, classifying and storing collected traditional culture contents, and automatically generating 3D digital timeline based on stored traditional culture contents. In addition, a system satisfaction questionnaire was developed to evaluate the usability of the system, and 19 students participated in verifying the system. As a result of the experiment, the satisfaction of the system showed that all items were 'satisfied' on average.

The purpose of this study is to collect biosignal data in a non-invasive and non-restrictive manner using a BCG (Ballistocardiogram) sensor, and utilize artificial intelligence machine learning algorithms in ICT and high-performance computing environments. And it is to present and study a method for developing and validating a data-based blood glucose prediction model. In the blood glucose level prediction model, the input nodes in the MLP architecture are data of heart rate, respiration rate, stroke volume, heart rate variability, SDNN, RMSSD, PNN50, age, and gender, and the hidden layer 7 were used. As a result of the experiment, the average MSE, MAE, and RMSE values of the learning data tested 5 times were 0.5226, 0.6328, and 0.7692, respectively, and the average values of the validation data were 0.5408, 0.6776, and 0.7968, respectively, and the coefficient of determination (R²) was 0.9997. If research to standardize a model for predicting blood sugar levels based on data and to verify data set collection and prediction accuracy continues, it is expected that it can be used for non-invasive blood sugar level management.

In order to expand the market of the domestic space information industry, which is currently saturated, overseas expansion is essential, but the prospects are limited. Therefore, an effective strategy of overseas expansion is needed. Given the current state of such spatial information industry, V-World is expected to play a very important role. In the world market for space information, in order to ensure the export competitiveness of the domestic space information industry, in the present study, research and development was carried out on the V-World-based packaged goods model as one possible method. First of all, to analyze the current situation and characteristics of the spatial information industry, to grasp V-World as a commodity and derive the relationship between foreign demand and V-World, the sales destinations and methods were defined. To formulate the basic strategy of the fusion-composite package export utilizing V-World on the basis of the basic concept of the product, the necessary components were designed. In response to this fusion-composite package product mix, the overseas promotion of spatial information-related companies it to be expected.

The purpose of this paper is to find out what values users pursue from a smart device based education service. For this purpose, a survey was conducted using a questionnaire that was developed based on the results of literature review and user interviews. Thirteen user expectation values were developed from the results of the survey: individually customized learning, anytime anywhere learning, learning for career, learning through interaction, learning from diverse resources, learning through cooperation, learning through interchange, self-directed learning, learning within actual context, learning with feedback, learning in spare time, learning with motivation & compensation, and step-by-step learning. In addition, the results of the survey also showed that the user expectation values of women, high school students and people who responded that they knew the smart device based education service very well were higher than those of other users.

Recently, most of computing technology is based on web. Therefore, the users register web services or needed resources, and they can find and use the registered item. These services can be used alone or can be used in combination. When the item is used in combination, the ordering and association of service is important, and an ontology that defined association of services is required. In this paper, we define association of services based on ontology, and propose a method that can be used by services integration. The proposed method provides an efficient retrieval service by compositing the ontology with the service area and data association area.

This study is to research the comprehensive recognition of male elderly about the sex life in old age. We collected data through face to face interview after obtaining the consents of 13 male elderly over 65 years old who reside in Kimhae Gyeongnam and Busan. The result of study showed that the sexual recognition of male elderly participants include the core concept of , , < the sex with restriction> and . In other words, the male elderly recognized the sexual life of old age as a natural and instinctive thing, the restrictions still exist including the negative recognition of family and surrounding people and diseases but it is found that the improvement of social recognition about sexual desire, the sex education and aggressive support for the various solutions are required. As the sexual awareness of the elderly is the comprehensive and broad study, the amalgamative and integrated study should be continued in the various fields. Through this, we tried to suggest the basic documents to the effective and differentiated individual sex consultation based on the empirical characteristics and desire of male elderly, and customized sex education and the development of local society program.

The purpose of this study is to investigate the effects of action learning on the satisfaction of majors by cultivating task-solving ability through self-reflection in the form of team learning for a certain period of time in the form of team learning by using action learning for students taking convergence curriculum in universities. The subjects of the study were 40 students from the Department of Sports Rehabilitation, a convergence of the Department of Sports and Health Management and the Department of Physical Therapy located in Jeollanam-do. This was conducted to confirm the difference in the effect of satisfaction. Comparison of changes in groups of experimental groups with action learning teaching methods showed significant differences in self-directed learning skills, problem-solving skills, and major satisfaction(p<.001)(p<.05). A significant difference in self-directed learning ability, problem-solving ability, and major satisfaction was also shown in the comparison of changes in control groups that applied traditional teaching methods(p<.05). Comparison of changes between groups showed significant differences in self-directed learning skills, problem-solving skills and major satisfaction(p<.05). Applying the action learning teaching method to the level of students in the convergence course will improve self-directed learning skills, problem-solving skills, and major satisfaction, and further research will be needed to expand the target and add variables to combine qualitative research.

Land information and building information have highest utilization and importance in real estate and city administration area. However, providing integrated information service was difficult because conflation and integrative utilization was not easy. In this study, necessity of integrated information system, direction of integration, method of conflation and design of integrated system for land and building information are presented. In addition, the prototype system is developed and possibility of application of integrated information is proposed. For this purpose, current situation of management of land and building information was analyzed. Based on the analysis, matching and conflation processes among spatial and attribute data were applied to land and building information. Using integrated land building information DB, integrated information system and functions were designed and the prototype system was constructed. At last, information service examples in real estate and city administration area were suggested through system operation by LX.
