Most previous studies on programming learning effect is limited to measuring the enhancement degree of creativity and problem solving ability. This study is to find out indexes related to programming ability, other than creativity and problem solving ability by the specialty-aptitude test(SAT) in the elementary school. For this, 4th grade elementary students took LOGO programming class and the achievement test. As a result, among 4 regions of SAT, all five indexes of intellectual ability is highly related to programming ability, indicating that students with high intelligence rather than creativity have higher programming ability and that for our experiment settings the reverse of the previous result stating that programming education positively affects the development of problem solving ability and creativity does not hold.

In recent years, Korean consumption trends have undergone rapid changes. Also, subscription economy has emerged and is growing as a new shopping method. The purpose of this study was to verify the relationship between consumer attitude and intention to continue to use of the consumption value of subscription service based on subscription economy. To this end, we analyzed the structural equation modeling for 300 consumers who used HMR products through subscription services. The analysis results are as follows. First, consumption value (functional, emotional, social and monetary) of HMR products perceived by subscribers had a significantly positive effect on consumer attitude except for monetary value. Second, consumer attitude was found to have a positive effect on consumers' intention to continue to use. This study contributes to the development of academic theories related to the subscription service in the early stages and provides managerial implications for HMR-related companies that want to utilize subscription service.

Method: A total of 13 elders with mild dementia in the data care center were participated. Manual and guideline of data care program was developed. Data care program was composed of movement/exercise, foot massage, music therapy, horticultural therapy, and art therapy. Data care program was performed by trained intervener for 32 weeks. Instruments were physical functioning such as hand grip strength., vital capacity, chiar stand test, sit and reach test, one leg standing, Berg' Balance scale, 6m Walk Velocity, stair climb, ADL, GDS-K, MMSE-K, Integrative Social Functioning Scale, cortisol, Ig A and Ig G. These were measured at the baseline, 16-week, and 32-week post-intervention by the trained nurses. Data were analyzed as Wilcoxon signed rank test. Results: For Hand grip, balance, and vital capacity, there was a significant difference between baseline and 16-week post-intervention(p<.05). For one leg standing, 6m velocity, there was a significant difference between 16-week post-intervention and 32-week post-intervention(p<.05). For Stair climb, there was a significant difference between baseline and 32-week post-intervention(p<.05). For depression and social functioning, there was no significant difference among baseline, 16-week, and 32-week post-intervention. For cognitive functioning, there was a significant difference between baseline and 32-week post intervention(p<.05). There was a significant difference of cortisol, and Ig G between baseline and 32-week post-intervention(p<.05). Conclusion: It would appear that physical fitness, functional performance, ADL, depression, social and cognitive functioning, and physiological indicator of community dwelling elders with dementia can be improved through day care program using multiple stimuli.

Brick is not only aesthetically beautiful and emotional material, but also eco-friendly and good building commodity for human health. Nonetheless, the use of brick has declined, due to the difficulty of building high-rise buildings and the limitation of the free form implementation. However, modern society is increasingly interested in environmentally friendly finishing materials for solving environmental problems. From this point of view, the brick architecture is being reexamined as a material to improve the living environment and to provide comfort without destroying nature. In addition, the development of digital technology enables the implementation of various types of masonry method and curved forms. Parametric design is one of the ways to realize the curved forms and various architectural expressions for brick architecture. In this background, the purpose of this study is to develop algorithms that can easily generate curved brick walls through parametric design, enable various pattern designs, and respond to real-time feedback. The details of the study are as follows. First of all, we examine organic architecture, the trend of brick architecture, and the concept of parametric design. Secondly, In order to generate curved surface with complex curvature, major planning factors affecting form generation are examined. Finally, we develop a parametric design method that consists of generating a curved surface for brick arrangement, implementing a parametric algorithm, and generating a curved form using bricks. Consequentially, we propose an algorithm that can maximize the use of ready-made bricks without using cut bricks to design curved walls and present efficient and economical design alternatives.

Recently, exhibition space has incorporated a format in which visual contents providers and viewers can directly or indirectly experience the space with a sense of immersion. By offering more extended spatiality within a limited space, such exhibition design is now transcending physical limitations and expanding to visual reality; as such, exhibition design demands the implementation of not only visual elements but information services generated between people, contents, and objects. To this end, this study examines the changes and the development direction of exhibition techniques that use Internet of Things (IoT), which is a representation of environmental change in exhibition design of our times; it also explores the various forms of change based on the perception of the visual contents (visual exhibits) users during the act of accumulating and using information through the smartphone communication of viewers who experience the space through IoT. Finally, the study conducts a case study on the relationship between a regular exhibition and an exhibition design that makes use of IoT, in order to propose an exhibition design with which to verify whether the viewers are immersed in and experience a sense of realism from visual contents by identifying the viewers' visual and emotional changes.

In this paper, we propose a method of recognizing emotions using PPG sensor which measures blood flow according to emotion. From the existing PPG signal, we use a method of determining positive emotions and negative emotions in the frequency domain through PSD (Power Spectrum Density). Based on James R. Russell's two-dimensional prototype model, we classify emotions as joy, sadness, irritability, and calmness and examine their association with the magnitude of energy in the frequency domain. It is significant that this study used the same PPG sensor used in wearable devices to measure the top four kinds of emotions in the frequency domain through image experiments. Through the questionnaire, the accuracy, the immersion level according to the individual, the emotional change, and the biofeedback for the image were collected. The proposed method is expected to be various development such as commercial application service using PPG and mobile application prediction service by merging with context information of existing smart phone.
