The method of operating a game could determine the psychological distance between the player and the game character, and thus, in the Virtual Reality, players' control methodologies are important to enhance their immersion. This study has the objective of examining the difference in games according to the method of operation based on the player's movements. This study researched the effect of the method of operating movement conforming to the movement of the character and the physical operation of the body on forming game experiences for the player. The result of performing an experiment increased reality for the game player through a controller in the shape of the actual control, to increase focus in the game. As so, game play through movements, including actual movements by the player displayed to enhance game satisfaction. In the part of media remediation field, Game can be defined as media which has their own unique hypermediacy. Especially, in the motion based game, players' movement mediates players and the game, therefore, players' movement could make players' experience augmented or immediate in accordance with the characteristics of movements. Even though sports and dances genres of motion-based games are common, RPG or adventure genres are rare. It can be explained that the characteristics of the action have been explained in the immediacy. In a game of fantasy, which is difficult to experience in real-life situations, the nature of the player's motion can increase the immersion of the game, which can contribute to utilization of players' motion and experience design in the various genres and suggestion of grounds theory. In addition, through this study, it is able to design motion-based games of various genres.

Objective : To compare the clinical outcomes and biomechanical effects of total disc replacement (TDR) and posterior cervical foraminotomy (PCF) and to propose relative inclusion criteria. Methods : Thirty-five patients who underwent surgery between 2006 and 2008 were included. All patients had single-level disease and only radiculopathy. The overall sagittal balance and angle and height of a functional segmental unit (FSU; upper and lower vertebral body of the operative lesion) were assessed by preoperative and follow-up radiographs. C2-7 range of motion (ROM), FSU, and the adjacent segment were also checked. Results : The clinical outcome of TDR (group A) was tended to be superior to that of PCF (group B) without statistical significance. In the group A, preoperative and postoperative upper adjacent segment level motion values were $8.6{\pm}2.3$ and $8.4{\pm}2.0$, and lower level motion values were $8.4{\pm}2.2$ and $8.3{\pm}1.9$. Preoperative and postoperative FSU heights were $37.0{\pm}2.1$ and $37.1{\pm}1.8$. In the group B, upper level adjacent segment motion values were $8.1{\pm}2.6$ and $8.2{\pm}2.8$, and lower level motion values were $6.5{\pm}3.3$ and $6.3{\pm}3.1$. FSU heights were $37.1{\pm}2.0$ and $36.2{\pm}1.8$. The postoperative FSU motion and height changes were significant (p<0.05). The patient's satisfaction rates for surgery were 88.2% in group A and 88.8% in group B. Conclusion : TDR and PCF have favorable outcomes in patients with unilateral soft disc herniation. However, patients have different biomechanical backgrounds, so the patient's biomechanical characteristics and economic status should be understood and treated using the optimal procedure.

Sleep apnea is a disease that causes various complications, and the polysomnography is expensive and difficult to measure. The purpose of this study is to develop an unrestricted wearable monitoring system so that patients can be examined in a familiar environment. We used a method to detect sleep apnea events and to determine sleep satisfaction by non-constrained method using SpO2 measurement sensor and 3-axis acceleration sensor. Heart rate and SpO2 were measured at the finger using max30100. After acquiring the SpO2 data of the user in real time, the apnea measurement algorithm was used to transmit the number of apnea events of the user to the mobile phone using Bluetooth (HC-06) on the wrist. Using the three-axis acceleration sensor (mpu6050) attached to the upper body, the number of times of tossing and turning during sleep was measured. Based on this data, this algorithm evaluates the patient's tossing and turning during sleep and transmits the data to the mobile phone via Bluetooth. The power source used 9 volts battery to operate Arduino UNO and sensors for portability and stability, and the data received from each sensor can be used to check the various degree between sleep apnea and sleep tossing and turning on the mobile phone. Through thisstudy, we have developed a wearable sleep apnea measurement system that can be easily used at home for the problem of low sleep efficiency of sleep apnea patients.

Korea has already entered into an aging society. In recent decades, the health problems for seniors has received considerable interest. We often see the elderly who have been struggled from discomfort or illness of the foot. Those foot related problems mainly cause from the use of improper shoes. Recently, shoe makers sell the shoes for seniors, so called comfort shoes, but the shoes are too expensive for seniors to buy easily. In this paper, we develop cheap insoles for seniors as an alternative of the comfort shoes and suggest the systematic process for the insoles development. This systematic process is as follows: 1) Survey the literature about the market of insole, 2) Investigate the standard size of body and foot for the seniors in Korea, 3) Analyze the customer needs by survey, 4) Study the walking pattern by experiments, and 5) Develop the novel insole for the seniors to relieve the inconveniences related with foot. From the newly developed insoles, the company B gains the sales increasing effect approximately 30% over through the increase in consumer satisfaction and company reputation and secures for intellectual property rights. Using the database from Korea Research Institute of Standards and Science, the reliability of developing technology of the functional insole has been obtained. The seniors are also enable to choose an alternative of comfort shoes for foot health. In the future, the insoles developed from this study have wide applications in the medical, cosmetic fields, and leisure sports fields. Accordingly, it seems to require more systematic studies utilizing Walk Analyzer and Foot Pressure Meter.

Background: The objective structured clinical examination (OSCE) is a widely used method to assess the clinical performance of students in clinical practice. Although OSCE has been used for undergraduate students of Korean medicine, this has not been widely reported. Methods: In 2020, the practical course for acupuncture and moxibustion medicine (acupuncture, electroacupuncture, pharmacopuncture, auricular acupuncture, and burning acupuncture) was taught using flipped learning, according to clinical practice guidelines, and assessed by the OSCE. The appropriateness of this model of education and its evaluation using OSCE were evaluated using a 5-point Likert scale, and the results were analyzed. Results: Of the respondents, 67% reported that the OSCE accurately reflected their competency, and 82% reported that online video lectures helped them to improve their clinical skills. The average adequacy score of the model was > 3.7/5, and the average adequacy score of the checklist used in the OSCE was > 4.1/5 for all 5 clinical application skills. The difference in the mean self-efficacy score between students who had taken the OSCE and those students who had not taken the OSCE, was highest in the burning acupuncture group (0.923). Conclusion: This study showed that students' satisfaction with the OSCE was high and flipped learning was an effective education model. In the future, models representing the human body or simulated patients should be used to evaluate students' skills and attitude.

This study evaluated the preference and wearing characteristics of existing fitness compression wear for elderly women and identified the problems and improvements of existing fitness apparel. Preference and wearing characteristics for 6 types (A-F) of upper and lower fitness compression wear were evaluated. Photos and drawings as well as the preferred designs and details were investigated after presenting the evaluation clothing. Evaluations were made on a 5 point Likert scale for the fitness, allowance, pressure, ease of movement, fabric material, and overall satisfaction after wearing. The design preference indicated that B type (26.6%) and C type (23.4%) were preferred in the top with C, E and F type preferred to the same ratio of 19.4% in the slacks. The fitness and allowance amount of the top B type were the most appropriate (${\geq}4$), the C type was in close contact (2.86), and the F type was inadequate in the neck circumference (1.77). The feeling of pressure was high in the waist, abdomen, thighs, and knees. The area where the elderly people want to improve their strength was the legs; in addition, a pattern design was needed to strengthen leg muscles when designing fitness compression wear. However, a design with excessive adhesion due to a muscle support band was shown to be not preferred. Therefore, depending on the activity, it is necessary to develop a fitness compression wear that applies an optimum stretching ratio of fabric based on body surface area changes.

This study is to analyze the concentration of visual perception of the subject through the eye-tracking experiments targeting popular characters and to investigate it is effective to highlight which part of the character in inducing consumers' interest and curiosity. As a result of the study, the subjects paid more attention to the face than the character's body, and also noted a little attention to auxiliary elements such as pants, tees, shoes, and whiskers. These results mean there is clearly different factor in which the subject's gaze on the character frequently stays and does for a long time. Therefore, the designers should recognize the differences of the concentration of visual perception by character components as a differentiating factor to feel the emotional satisfaction such as the user's interest, empathy, and immersion in the character and actively reflect it when developing the character design. In addition, there was a difference in the visual perception concentration of each of the auxiliary elements, and if careful research is done on whether the influence factors are also due to individual characteristics or another influential factors, it will be a wider study on character design.

Background Gynecomastia is a common condition that can cause severe emotional and physical distress in both young and older men. Patients in whom symptomatic recalcitrant gynecomastia persists for a long time are potential candidates for surgery. Methods From January 2014 to January 2016, 15 patients underwent correction of gynecomastia through a single 3-mm incision at our institution. Only patients with true gynecomastia underwent surgery with this new technique. Through the small incision, sharp dissection was performed in a clockwise and counterclockwise direction describing two half-circles. Health-related quality of life and aesthetic outcomes were evaluated using a modified version of the Breast Evaluation Questionnaire (BEQ). Results The patients' average age was 23.5 years (range, 18-28 years), and their average body mass index was $23.2kg/m^2$ (range, $19.2-25.3kg/m^2$). One case was unilateral and 14 cases were bilateral. The weight of glandular tissue resected from each breast ranged from 80 to 170 g. No excess skin was excised. Bleeding was minimal. The mean operating time was 25 minutes (range, 21-40 minutes). No complications were recorded. All lesions were histologically benign. The patients' average score was 3.5 (on a 5-point Likert scale) in all domains of the BEQ for themselves and their partners. Conclusions In this study, we demonstrated the safety and reliability of a new technique that allows mastectomy through an imperceptible 3-mm incision. We obtained high patient satisfaction scores using our surgical technique, and patients reported considerable improvement in their social, physical, and psychological well-being after surgery.
