At the Brain MRI examination, RF Pulse are irradiated on the human head in order to acquire MR images. At this time, a considerable part of the irradiated RF Pulse energy is absorbed in our body and the temperature of the human head will rise depending on the degree of exposure, so it will affect the human head. Even if the same RF Pulse energy is given, if the metal is inserted in the human head, the conductivity of the human head is greatly increased by the metal, so the SAR value increases and the temperature also rises. Therefore, we started this research with the question as to whether there is difference between the change in SAR value and temperature displayed on the head of the human according to use or not of the dental implant. Experiments were using the XFDTD program on a 128 MHz RF Pulse frequency by a 3.0 tesla MRI. We can see that both are increasing that the average value of SAR and temperature that absorbed by the human head model used the dental implant. In addition, the average maximum SAR value and the maximum temperature rise in the brain part are shown below the international safety standard value but the influence can not be ignored because of the result may change according to the increase in the number of dental implant. And as future tasks. we need to the simulation of temperature rise and SAR due to an increase in the number of implants and volumes of teeth, dental implant material.

Purpose: For modern people, stress is a major cause of all physical and mental illnesses. Natural healing is useful for a healthy life by reducing stress because it not only heals diseases, but also heals the body, mind, and diseases holistically. This study explores the stress change process experiences and essence of participants in the Holistic Therapy program through the grounded theory method. Method: Of the 62 participants in the Holistic Therapy program, data were collected two to three times for 12 people with large stress changes, about 90 minutes each, and through individual interviews. Data analysis was performed by open coding, axial coding, selective coding, process analysis, core categories, and type analysis according to Strauss & Corbin's grounded theory method. Results: As a result of data analysis according to the grounded theory method, 106 concepts, 47 subcategories, and 21 categories were finally derived. The derived stress change process appeared in four stages: fear, conflict, effort, and adaptation to change. Based on the results of selective coding, the core category was derived as the process of 'self-change and life change through stress overcoming'. The adaptation types that appeared in the stress change process were thought avoidance type, emotional suppression type, and behavioral impulse type. In the Holistic Therapy program, the stress of 12 participants with a large trend of stress change changed by experiencing happiness and pleasure through love and respect. As participants participated in the program, they escaped from negative emotions, and as their lives changed, they became motivated to live, and they lived a changed life through hope and vision. Conclusion: Conclusion: It was confirmed that it was useful as a healing therapy through the experience of stress change process through participation in the Holistic Therapy program. This study is meaningful in that the Holistic Therapy program explores the stress change process, stage, and stress application type as grounded theory.

Archival symposium was a time when men thought thoroughly about what archives were, and to carefully record such thoughts. In the time of archival symposium, I observed the people archiving. To bring out a thought for a man was a physical action that moves his own desire, language, emotion and senses simultaneously. In philosophy thought is not merely a logical and cognitive act. Thought is a physical act that includes logical thinking, feeling, emotion, will, and on. When there is a emotional change in the body, an idea about that change forms. Emotional change acts as a force that increases, decreases, accelerate and hinder the body's abilities. However, there were no suggestions for philosophical concepts from the start. Love is not taught by someone. At some point without oneself knowing we start love and really experience with our bodies what love is, and in this repeat love and undergo all these emotions. Would not the overall story of life be as such. It is different from building a car in a factory. When the archival symposium starts, we asked you to think about what archives are, and to record with such thoughts as reference. Archival symposium is still a proper noun. With the wish for it to become a general term, I report on the process and meaning of archival experiment that is the archival symposium.

This study aims to evaluate the feasibility of the disinfection of clinical ultrasound probes using the vapor fumigation method, which can quickly achieve high-level disinfection. Upon the inspection of the microbial contamination level of clinically used ultrasound probes, nine different types of bacteria were detected. The disinfection efficacy of 7.5% and 35% hydrogen peroxide (H₂O₂) was comparatively tested for the detected microbes. The 35% H₂O₂ demonstrated superior efficacy per disinfection duration. No significant change was observed in the rubber component of the ultrasound probes as a result of the 35% H₂O₂ disinfection treatment. The probes were contaminated with the microbes detected in the microbial contamination level inspection and subsequently disinfected using the novel medical disinfector that utilizes the vapor fumigation method. As a result, the disinfection using the novel device achieved 100% eradication of the microbes from the probes.This study demonstrates that the novel vapor fumigation method-based disinfector provides a faster and more powerful means of disinfection than the conventional disinfection methods. Therefore, the novel disinfector has the potential to be used as a convenient ultrasound probe disinfector in clinical settings.

Interactive games allow users to obtain embodied experience using the bodies as controllers. The same is true in interactive media arts where users engage in active participation. In contrast to video games, physical body feedback is desired and such practice can be found in robotic arts. I suggest that interactive media arts and interactive games should share common foundations. In this context, I introduce and explain an interactive robotic art work implemented. This work is a musical instrument that employs a robot which travels sitting on two strings in response to audience positions. In results, the robot modulates the vibrations of the strings by causing the effective lengths of the strings changed. The robot uses an economic multi-cell proximity sensor in order to track the audience. In the interaction, phenomenological tension could take place in the performative narrative space. In this paper, I discuss this interactive robotic work in the context of interactive games with a few examples.

The purpose of this study was to examine the child-rearing difficulties of mothers with twins in an effort to discuss how to lend assistance to these mothers, as the birth of twins has been on the rise. The participants in this study were six mothers who resided in the city of P and raised infant twins. They were interviewed twice in depth from December, 2012, to July, 2013. The findings of the study were as follows: First, as for the difficulties of their children perceived by the mothers, their children had to share everything, no matter if it was good or bad, and they were confronted with environmental constraints. In addition, they were fragile from the moment they were born. Second, concerning the self-perceived child-rearing difficulties of the mothers, they had no time to take care of themselves at all and felt lonely all the time. And they were under pressure due to financial burden. In order to help these mothers and their children to tide over their difficulties, there should be a change in the way people in general look at twins, and the establishment of emotional and financial support systems is required. The findings of the study are expected to provide some information on how to offer full-fledged support for mothers with twins.

Approximately 0.7 millions dining business exist all over the country and the industry gains 33 trillions sales every year. Although the characteristics, preference factors, and consuming trends of the consumers in this area are diverse and unpredictable than those in other segments, it is actual that the industry has not been divided as a specified market suited to the real state of affairs in the nation. Therefore, in order for appropriate marketing strategies, it will be necessary to focus on extending product classification, diversifying brands, health marketing, and marketing by ages, by generations, and by life patterns. In addition, economically superior position can be established by subdividing strategies meeting various needs and expectations of consumers.

From November 1996 to April 1997, the rockfish, Sebastiscus marmoratus (Cuvier et Valenciennes) was reared in laboratory, and observed eggs development and morphology of larvae. The eggs of this species are demersal and adhesive, and their diameter were varied within 0.76 to 0.82 mm. The color of yolk is light yellow in early developmental stage, and then turned to orange before hatching out. The yolk contained numerous tiny oil globules. Hatching began about 33 hours and 30 minutes after insemination at $10.0{\sim}14.5^{\circ}C$ of waters. The newly hatched larvae were elongated in shape and 1.62~1.68 mm in total length (TL) with 7~8+16=23~24 myomeres. The larvae absorbed yolk material and oil globule completely in 14 days after hatching and became postlarvae. The spawning season of adult rockfish may be supposed to be from February to March in the southern sea of Korea.
