The purpose of this study is to measure and analyze indoor air flow in order to determine the possibility of HVAC operations causing airborne infections in outpatient departments of general hospitals in South Korea. Among 10 general hospitals, the emergency department in the children’s ward in the K University General Hospital using a typical central HVAC system was selected as the measurement space for this study. The indoor air flow direction was confirmed by measuring the interzonal air flow rate, differential pressure and tracer gas concentration for the central HVAC system of the study space, and three different changes in the outdoor air intake rate were applied to determine the interzonal air flow diffusion state. The study space had a high possibility of receiving patients that could cause airborne infections and there were risks of secondary infections from the airflow diffusing into adjacent spaces such as the otorhinolaryngology department or the waiting room corridor. The measurement results showed that using an HVAC system with 100% outdoor air reduced the concentration of gas rapidly, thereby lowering the probability of infection, and that the airflow did not diffuse into adjacent spaces when the study space had negative pressure.

In statutes on the promotion of distribution of new and renewable energy, which were revised in 2014, daylight system and fuel cell were added in addition to existing new and renewable energy sources. This study, therefore, aimed at setting up targets for the introduction of daylight system and analyzing the installation rate of new and renewable energy which can be provided by daylight system for the aggressive use of daylight system, thereby deducting the optimal combination ratio with other new and renewable energy sources. The results of the study are as follows. First, when a prism-shaped daylight system was installed to a round indoor gymnasium among domestic indoor gymnasiums, out of a supply obligations allotment rate of 15% of new and renewable energy, the rate of daylight system was basically set at 2.5%. Second, therefore, with daylight system coming first, the lacked supply obligations rate was taken up by solar photovoltaic, solar heat and geothermal heat. In addition, using the KRESS Program, economic, technical, environmental and complexity evaluations for the upper 5% was made, deducting the optimal ratio of the system. The results produced the following optimal combination ratios: solar photovoltaic (83.3%) in economic evaluation, solar heat (8.3%) and geothermal heat (75%) in technical evaluation, solar photovoltaic (83.3%) in environmental evaluation, and solar photovoltaic (83.3%, the same as in economic evaluation) in complexity evaluation.

본 연구는 아헹가 요가 프로그램이 중년여성의 하체불균형에 미치는 영향을 분석하는데 그 목적이 있다. 연구의 대상자는 35-60세 사이의 중년여성으로서 요가 수련의 경험이 없으며 다른 운동 훈련에 참가 하지 않고, X-RAY검사와 간스테드 테크닉(Gonsted Technique) 분석을 통하여 골반불균형이면서 하지 길이의 차이가 있는 중년여성 24명을 선정하여 12주 동안, 주3회, 1일 90분 동안 수련하였다. 통계방법은 대응 t-검정을 실시하여 수련 전과 후를 비교하였고, 유의 수준은 0.05로 설정하였다. 이 연구의 결과는 첫째, 아헹가 요가는 골반 불균형을 교정하는데 통계적으로 유의한 결과를 나타냈다. 즉 골반불균형 개선에서 좌·우 엉덩뼈 높이(p < 0.001), 좌·우 엉덩뼈 넓이 (p < 0.001), 좌·우 엉덩뼈 길이 ((p < 0.001), 좌·우 엉치뼈넓이 (p < 0.001)에서 수련 전보다 수련 후 그 차이가 감소하는 유의한 변화를 보여주었다. 둘째, 하지 길이의 변화에서는 아헹가 요가 수련 전 보다 수련 후에 좌·우 하지 길이 차이 (p < 0.001)가 현저하게 감소하였으며 통계적으로 유의한 효과를 나타내었다. 이상의 연구 결과에서 아헹가 요가 수련이 중년여성의 신체불균형을 교정하는데 매우 효과가 크다는 것을 알 수 있었다. The purpose of this study was to investigate the effects of Iyengar yoga practice on the lower body imbalance in middle-aged women. The subjects (n=24), who had not performed yoga training prior to this study (and) were not attending any other training programs, participated after undergoing an X-RAY examination with the Gonstead Technique and then their lower body imbalance (was reevaluated). The subjects completed the yoga program for 12 weeks (3 times per week, 90 minutes per session). The data were analyzed with the paired t-test and alpha was set at 0.05. It was found that 1) the height differences between the right and left iliac crests (p < 0.001), width (p < 0.001) and length (p < 0.001) differences between the right and left iliac fossa, and width differences between the right and left sacrum (p < 0.001) were significantly reduced after the training program. In addition, 2) the lower limb length discrepancy was significantly reduced (p < 0.001). Our data suggest that Iyengar yoga training for 12 weeks reduces the pelvic imbalance and length differences between the right and left lower limbs in middle-aged females.

Choristoma is a growth of normal tissue that occurs at an abnormal region. In the oral cavity, osseous choristoma that has a normal bone feature mainly has been appeared. It is mainly occurred on the tongue. So, It can be found in dental practice or in discomfort in the mouth. Osseous choristoma in the oral cavity is extremely rare. But It can be treated excisional biopsy under local anesthesia. The prognosis is very good. This case is a report of osseous choristoma on the dorsal surface of the tongue. A 17-year-old female patient presented with a foreign body sensation of the tongue. A diameter of the mass is 0.7cm, and there is no pain. Panoramic radiographs showed a radiopaque image in the form of a double image. An excisional biopsy was performed and diagnosed as an osseous choristoma. 12 months after the resection, there were no signs of recurrence. Intraoral osseous choristoma is very rare, but it is clinically very simple and can be found in dental radiographs. We present this case because of Dentists who examine the oral cavity of the patient can easily diagnose the lesion and treat it by simple resection

최근 인간의 유희욕구를 자극하여 흥미를 유발시키고 몰입을 유도하는 게이미피케이션(Gamification) 기법이 대두됨에 따라 헬스케어(Health-care), 에너지 절약, 교육 등 다양한 분야에서 그 가치와 중요성을 인식하고 있다. 그러나 현재 게이미피케이션 요소의 도출 및 전략에 관한 연구가 부족한 실정이므로 사용자의 행동유발 증진을 위한 전략적 연구의 수행이 필요하다. 따라서 본 연구는 운동 분야를 중점으로 여러 연구자들이 제시한 게이미피케이션 요소를 수집한 후 어피니티 다이어그램(Affinity Diagram) 방법을 사용하여 일곱 가지 전략 (보상, 도전, 성취, 경쟁, 관계, 접근, 자기표현)으로 분류하였고, 각 전략의 효과들을 정리하여 제시함으로써 게이미피케이션 전략의 무분별한 제공을 경계해야 한다는 목적을 담고 있다. 연구결과 보상전략은 운동수행향상과 내적동기에 긍정적인 영향을 미치며, 도전전략은 자기효능감과 신체기능을 향상시키고, 성취전략은 운동속도와 거리의 증가 및 만족감 개선에 도움을 준다. 경쟁전략은 목표성취율을 높여주고, 관계전략은 운동 습관을 형성시키며, 접근전략은 흥미를 유발하여 행동증진에 효과적인 것으로 나타났다. 마지막으로 자기표현전략은 행동변화에 긍정적인 영향을 미치는 것으로 나타났다. 본 연구에서 제시하는 전략들을 건강 행동증진과 관련된 분야에 적용하여 사용자의 능동적 참여와 몰입을 유도하는 긍정적 결과를 이끌어 내기를 기대한다. 차후 연구에서는 개인의 성향에 따른 게이미피케이션 전략의 행동의도, 행동몰입, 선호도에 관하여 양적으로 연구할 예정이다. Along with the recent appearance of the method, gamification, which raises interest and causes immersion by stimulating the human desire for amusement, its value and importance are recognized in various fields such as healthcare, saving energy, and education. As for now, however, there are not enough studies on deducing the factors of gamification and strategies, there need to be strategic studies on how to trigger users’ actions. So this study collected factors of gamification that several researchers suggested focusing on exercise, classified them into seven strategies(e.g., reward, challenge, achievement, competition, relationship, approach, and self-expression) using affinity diagram, and this paper aims to organize and present effects of each strategy and imply that we should be wary of indiscriminate supply of gamification strategy. The result of this studyr shows that reward strategy has a positive effect on improving exercise performance and inner motive, challenge strategy improves self-efficacy and physical functions, and achievement strategy helps improving exercise speed, distance, and satisfaction. Competition strategy increases the rate of achieving goals, relationship strategy forms exercise habit, and approach strategy raises interest and is effective in improving behavior. Lastly, self-expressing strategy was found to have a positive effect in changing behavior. It is expected that the strategies that this study suggests are applied to the areas related to improving health behavior and derive positive results that induce users’ active participation and immersion. In the following study, behavior intention, behavior immersion, preference of gamification strategy according to individual tendency will be quantitatively studied.
