오늘날 사람들의 평균 생활소득 증가에 따라 삶의 질 향상에 대한 관심이 늘어나고 있다. 그중에서도 반려식물에 대한 관심과 그에 따른 반려식물을 키우는 데 도움을 주는 것과 관련된 많은 프로젝트가 진행되고 있다. 본 논문에서는 아두이노 기반의 휴대용 발아기를 개발하면 이동이 쉬워 언제 어디서나 식물의 상태를 확인 가능하여 편리하게 관리 할 수 있고 스트레스 해소와 힐링(Healing)을 위해 연구하게 되었다. 이를 위하여 임베디드 시스템에 온도, 습도의 센서를 부착한 센서를 통해 데이터를 수집, 관리하고, 스마트 기기에서 현재 온도와 습도, 식물 Data까지 관측 및 제어할 수 있도록 하여 기존의 일반적인 농업에서 진보된 스마트 도시농업을 이루고자 한다.

In order to resolve coverage hole problems caused by indoor-BS (IBS) faults, we propose a new frame structure and practical algorithm based on optimization technique. Our main contributions can be described as follows: 1) a frame structure with healing channels for solving abnormal IBS faults; and 2) an efficient heuristic resource allocation algorithm with fixed IBS selection to reduce the complexity for the optimization problem. Through intensive simulations, we evaluate the performance excellency of our proposed algorithm with respect to average cell capacity and user fairness compared with conventional algorithms.

To investigate the microcrack healing behavior of $Si_3N_4-20wt\%SiC-8wt\%Y_2O_3$ composite ceramics(SNCY8), we observe the crack length evolution a! the time of 20, 40, 60 minutes with in-situ optical microscopy by varying healing temperature of $800\~1200^{\circ}C$. Crack healing obviously occurred as heating temperature and time increased. We proposed a simple model of effective diffusion based on the crack length evolution with healing condition, and determined the effective diffusion coefficient as Our result implies that we may predict the healing ability quantitatively with temperature and time in structural ceramics through the effective diffusion coefficient model.

To provide network reliability in indoor wireless communication systems, we should resolve the problem of unexpected network failure rapidly. In this paper, we propose an adaptive resource management (ARM) scheme to support seamless connectivity to users. In consideration of system throughput and user fairness simultaneously, the ARM scheme adaptively determines the set of healing channels, and performs scheduling and power allocation iteratively based on a constrained non-convex optimization technique. Through intensive simulations, we demonstrate the superior performance results of the proposed ARM scheme in terms of the average cell capacity and user fairness.

Purpose The purpose of this study was to investigate the effects of contact handorientation response(CHOR) during sit-to-stand(STS) in people with stroke. Methods The subjects of the study were Thirty hemiplegia participated (Rt. hemiplegia/Lt. hemiplegia: 15/15, mean age: $65.82{\pm}8.53$) in this study. The analysis of muscles activation (rectus femoris, biceps femoris, tibialis anterior, gastrocnemius) distribution was conducted by the EMG, and the analysis of foot pressure distribution was conducted by the resistive pressure sensor. Hemiplegic stroke patients were instructed to perform STS three times with the non-affected side hand and affected side hand on the table. Results There was a significant positive correlation between rectus femoris, tibialis anterior muscle activation and affected side hand contact during STS(p<0.05). The STS correlated with the foot pressure in the affected side hand contact(p<0.05). Conclusion AS a result, CHOR during STS is related to muscle activation and the characteristics of foot pressure. This information was observed in the affected side hand contact on the table, suggestion that rehabilitation programs should be implemented.

This paper shows the need to study the commercialized color book game screen composition and manipulation interface type in order to enhance the utilization of the serious game mobile coloring book game, which is utilized from the learning of color sense in modern people and children to the hobby life of adults or old people. For the healing of modern people, we are going to look at the design configuration of game screen interfaces in simple and fun mobile coloring book games, and propose a new way to improve interface design that improves uncomfortable design by organizing and analyzing basic interface UI design types.

Despite people's expectation, COVID-19 has turned out to be a burden people have to carry for a while. The age of "Untact" has come. While many outdoor activites have been restricted, it is crucial to find other ways to maintain physical/mental health ideally indoors. As a mediative gesture, people are now taking notice of 'Console games', through which they can party, travel, and exercise in virtual reality even harder than in real life. In thesis, we will examine Nintendo Switch Consoles in relation to direction Korean game industry has to take to maintain people's physical/mental health.

With the recent revitalization of virtual reality and game industries, digital therapeutics for medical purposes are emerging. Digital therapeutics refer to sports-based therapeutics such as virtual reality contents and games that are effective in preventing, managing, and treating diseases, not drugs. Through this study, we plan and develop contents for healing and brain enhancement using virtual reality technology as a therapeutic digital therapy. Through this, it can help to improve the brain of children who are dependent on electronic devices in the digital age and rarely use their brains.

This paper suggests facility planning ideas for recreational fishing complexes suitable for family anglers. Existing recreational fishing parks are only equipped with facilities for angling. There are many needs for recreational fishing complexes in coastal fishing villages that include not only angling facilities but also various marine leisure and sports facilities. In this paper we suggest concepts for recreational fishing complexes and define four types of complexes in terms of facilities planning. These four types of complexes are: 1) suburban leisure sports, 2) suburban healing and relaxation, 3) penturban experience and activities, and 4) penturban culture and recreation. Then we propose facility composition in detail for each type. Also we suggest site selection criteria for the village complex, facility infrastructure planning ideas, and leisure facilities (elementary and specialized) for recreational fishing complexes.

Contemporary era has witnessed a diversity of emotion and emotions being expressed through consumption. This paper examines the relationship between social paradigms and emotional design by means of literature study. In sections 2 and 3, I examine the prevalent social paradigms and the concept/development of emotional design. In section 4, I show the correspondence between social paradigms and specific types of emotional design. More specifically it is shown that "pluralism and decentrality" has led to fun design, individual design and participative design; "emotional revolution" has given rise to multi-sensory design, design with positive feelings, design with negative feelings and aesthetic design; "non-materialistic values" have their correspondence in design as performance and story-telling in design; and "organic worldview" finds its expression in ecological design with a wellness emphasis, and in interactive emotional design.
