The purpose of this study is to develop a meditation application to promote home practice in a meditation-based intervention program and test its effects. In most cases, meditation-based intervention programs put an emphasis on home practice, which means it is an important matter to increase motivation for home practice and encourage people to do home practice more. The investigator administered an eight-week Korean Mindfulness-based Stress Reduction (K-MBSR) program to college students participating in a liberal arts course at A University. While the experiment group (N = 22) received a meditation application, the comparison group (N = 19) received no meditation application. The amount of home practice was measured based on the practice logs kept by the participants. The difference in psychological effects between the groups was checked by measuring mindfulness, subfactors (noticing and return to body) of body awareness, life satisfaction, acceptance action, and sleep quality before and after the experiment. The findings show that the experiment group recorded significantly greater amounts of home practice than the comparison group. As for the effects of meditation, the experiment group recorded higher points in mindfulness, body awareness, life satisfaction, acceptance action, and sleep quality than the comparison group. These findings demonstrate that a meditation application can be useful as a means of assistance to promote the effects of a meditation-based intervention program. The study also discussed proposals for a follow-up study.

The purpose of this study was to examine the effect of myofascical release (MR) on the degree of pain and nerve conduction velocity (NCV) in middle-aged women. Participants were 28 middle-aged women and MR carried out three times (1, 3, 5 day) at intervals of two times. We did survey about changes of pain before the MR and how they changed after the MR. Also measured pressure pain threshold (PPT) and visual analogue scale (VAS) by using the algometer at trapezius muscle. In median nerve, we did motor nerve conduction velocity (MNCV) test and sensory nerve conduction velocity (SNCV) test for measuring incubation period, amplitude and nerve conduction. The most painful time was 18~21 and the most painful part was shoulder. The pain scale, PPT and VAS after the MR had significantly decreased than before the MR. The latency was significantly decreased and the amplitude was significantly increased in the MNCV and the latency was significantly decreased in the SNCV after the MR. Also it was effective in ameliorating pain scale and latency of NCV. Consequently, the MR can be effective in prevent pain scale caused by fatigue in middle-aged women as replacement therapy.

The Plastic material had been developed in the middle of the 19th century as an alternative material. Along with the development of the electrical engineering industry, it cropped up into center stage as an effective material and has increasingly expanded its use. As such, the plastic material has bound deep-seated ties with the design activities of industrial products, coming into the main material for a variety of industrial designs. Despite its dose affinity to design function in terms of its materialistic property, we have rarely seen examples of intensive study on the realtionship between plastics and designs. This study aims to find the importance that the substance affects industrial products in designs along with the development of plastic materials. With the objective in mind, we made a review of the streamline stylishness that had flourished in the twenties and thirties of the 19th century. Through this study, we understand that the plastic material has a close realtionshop with design activities in three different aspects. First, its amorphous state of nature makes it possible to change into any shape one desires in plastic surgery, which feature in turn influences the moulding of any design forms. Second, the plastic material is best suited to mass-manufacture, which induces to reduce the cost of production. Hence, the expansion of design industry. Third, the plastic material allows the multiple variety of colors, sensitivity, gloss and patterns and infinitely large possibility ranging from natural senses to human senses with the result that numberless diversity of designs cdould come into being.

Realtime visibility measurement using camera is a new method which can collect some realtime visibility data similar to those of the human eyes, and can replace the existing methods using the expensive optical equipment. There have been a few attempts to measure visibility by extracting depth and three-dimensional structure under bad weather conditions. However, if there are many movements of objects in the image, these approaches seem to be inappropriate. In addition, the realtime visibility measurement will require a relatively simple and fast processing. Typically the contrast degrades exponentially in the bad weather. Therefore, in this paper we propose an easy and quick method that extract contrast from images using a moving area filter and measure visibility by mathematically modelling of the relationship between image contrast and visibility. The moving area filter is used for removing the area of the sky and moving objects that affect visibility measurement on images. The method proposed here can make possible not only realtime visibility measurement from images taken by CCD cameras, but also steady visibility measurement by using the moving area filter in case of much traffic on the road.

Childhood depression was not officially accepted as a separate diagnosis until 20-25years ago. Although DSM-III R criteria gave us a starting point and are gaining acceptances as a useful tool for diagnosing childhood depression recently, many professionals feel that additional modifications are needed to better reflect the developmental aspects of children. And because children are relatively poor in expressing their moods or feelings due to weak reality sence and/or cognitive and linguistic limitations, the author too carefully suggest that developmental perspectives of children should be considered in diagnosing childhood depression. Little is known about the extent to which childhood depression precedes adult depression and persists into adult life and about the impact of it on the personality formation. Some evidences that childhood depressive symtoms can be quite enduring make it important to make an early diagnosis and treatment.

In 2019, COVID-19 changed many people's lives. Among them, metaverse supports non-face-to-face services through various methods, replacing daily tasks. This phenomenon was created and formed like a culture due to the prolonged COVID-19. In this paper, the fun elements used in the existing game were organized to find out the fun factors of the metaverse, and the items and contents were reclassified according to the metaverse with five experts. Classification was classified using reproducibility, sensory fun [graphic, auditory, text, manipulation, empathy, play, perspective], challenging fun [absorbedness, challenging, discovery, thrill, reward, problem-solving], imaginative fun [new story, love, freedom, agency, expectation, change], social fun[rules, competition, social behavior, status, cooperation, participation, exchange, belonging, currency transaction], interactive fun[decision making, communication sharing, hardware, empathy, nurturing, autonomy], realistic fun[sense of unity in reality, easy of learning, adaptation, intellectual problems solving, pattern recognition, sense of reality, community], and creative fun[application, creation, customizing, virtual world].

Lines are the oldest visual elements in human history and are closely related to human life and drawings and symbols drawn with lines on cave paintings and rocks have existed as alternative images for human survival. In arts the line reveals the core of the object within a short period of time and in art therapy it becomes a medium that can diagnose the client's psychological state and intervene therapeutically. However although line drawing has therapeutic importance in the process as well as diagnosis studies on its effectiveness and therapeutic characteristic have not been actively conducted. Therefore in this study the characteristics related to line art in art therapy are first derived through 'Triangular Verification of Theory', 'Qualitative Content Analysis', and 'Finding Common Parts' in domestic and foreign literature. As a result I will examine the Movement which is a key therapeutic element of line drawing in connection with the brain structure. Through this I will examine the therapeutic mechanisms that affect the body, brain and mind of the movement of line drawing and examine and suggest how it can be used in art therapy.

Windows are essential and important architectural elements for the organization of architectural spaces, and they give character to the space and have a great impact on the reaction of users. Virtual windows are installed to activate architectural spaces such as underground spaces where windows cannot be installed, and to provide a sense of psychological security to users in hospital clinics, etc. In this study, we reviewed the literature and collected and analyzed the precedents of virtual windows to discuss the factors necessary to improve the realism of virtual windows. The factors that affect the realism of virtual windows are further grouped into five categories: 1. Use of reproduced images or videos for views, 2. Representation of temporality, 3. Responsiveness to changes in the observer's perspective, 4. Realistic reproduction of sunlight, and 5. Provision of non-visual sensory elements. Virtual windows are not just a replacement for traditional windows, but a way to realize a virtual environment using digital media, and it is necessary to expand the discussion to the realization of the virtual environment and the relationship with architectural elements.

Objectives : The conventional removable appliance, composed of wires and acrylic resin, had unaesthetic results and poor retention. The flexible denture, as an alternative, presents improved aesthetics with the thin and strong resin retentive area. In addition, it also enhances patients' sensory function as a result of decreased volume of denture base. The flexibility of the flexible denture reduces the possibility of fracture and distributes the masticatory forces transmitted to the abutments and residual bone tissue. This report describes a 10-year-old girl and a 6-year-old boy with oligodontia treated with the flexible dentures as an alternative to conventional removable appliances. Methods : Impression was taken using alginate material and sent to a laboratory with the bite for fabrication of the flexible denture. Prior to try-in, the flexible denture was immersed in water at $90^{\circ}C$ for one minute and cooled. Impinging area of the denture was checked by $Fit-Checker^{(R)}$ and removed and the denture was delivered to the patient. Results : Both patients were satisfied with the flexible dentures, which presented improved retention and aesthetics. Conclusion : For patients with oligodontia, flexible dentures can be considered as a treatment of choice, which may replace the conventional denture.
