양안시차를 이용한 입체 디스플레이는 입체감과 편안함이 상충하는 특징이 있다. 본 논문에서는 이를 해결하기 위해 영상 특성에 따른 길이 조절을 통해 인지되는 입체감을 최대한 떨어뜨리지 않으면서 불편함을 최소화하는 방법을 연구하였다. 인간이 입체를 인지하는 기저는 상당히 복잡하며 영상의 여러 형태에 따라 동일한 깊이(양안시차, disparity)를 주는데도 입체감과 편안함이 다르게 인지된다. 따라서 영상 형태에 따라 다르게 인지되는 영향 인자를 선정하고 이에 대한 깊이감과 편안함의 관계를 실험을 통해 분석하여 적합한 값을 얻었다. 이를 표시되는 입체 디스플레이에 적용하여 들어오는 영상을 처리하여 영향 인자의 정도를 구하고 이에 따라 깊이가 조절(Depth Scaling)되도록 하여 편안한 입체 영상을 구현하였다.

This study explored the determinants that influence purchase intention in online shopping based on augmented reality applications. The main results are discussed focusing on hypotheses as follows. First, interactivity had a positive effect on psychological ownership. Second, interactivity had a positive effect on decision comfort. Third, psychological ownership had a positive effect on decision comfort. Fourth, psychological ownership had a positive effect on purchase intention. Fifth, decision comfort had a positive effect on purchase intention. Therefore, in online shopping based on augmented reality applications, interaction determines psychological ownership and decision comfort, and psychological ownership and decision comfort can be evaluated as key factors that promote product purchase intention in online shopping. In order to increase purchase intention in online shopping, a marketing strategy is required to increase interactivity, psychological ownership, and decision comfort through augmented reality applications.

Purpose: The purpose of this study was to identify the effects of the heated-humidified breathing circuit applied on the body temperature, shivering, and thermal comfort of general anesthesia patients. Methods: The participants were patients who received general anesthesia at University Hospital K located in City B, with 25 patients in the experimental group and 25 patients in the control group. The period of this study was from Mar 19 to Apr 26, 2019. The experimental equipment included a heated-humidified breathing circuit, which connects the intubation tube with the anesthesia machine for mechanical ventilation after airway intubation in general anesthesia patients. Results: The body temperature, shivering, and thermal comfort after surgery were significantly different between the two groups (p<.001). However, the body temperature during surgery was slightly different between the experimental group and the control group. Conclusion: A heated-humidified breathing circuit may be actively used in a warming method to prevent the hypothermia of general anesthesia patients.

Purpose: The purpose of this study was to examine the effect of pre-warming on body temperature, anxiety, pain, and thermal comfort. Methods: Forty patients who were scheduled for abdominal surgery were recruited as study participants and were assigned to the experimental or control group. For the experimental group, a forced air warmer was applied for 45-90 min (M=68.25, SD=15.50) before surgery. Body temperature and anxiety were measured before and after the experiment, but pain and thermal comfort were assessed only after the surgery. Hypotheses were tested using t-test and repeated measured ANOVA. Results: The experimental group showed higher body temperature than the control group from right before induction to two hours after surgery. Post-operative anxiety and pain in the experimental group were less than those of the control group. In addition, the score of thermal comfort was significantly higher in the experiment group. Conclusion: Pre-warming is effective in maintaining body temperature, lowering sensitivity to pain and anxiety, and promoting thermal comfort. Therefore, pre-warming can be recommended as a preoperative nursing intervention.

This study was cosmetic contact lens wear for up to 2 weeks in for the evaluation of the insertion. In 1 week during weeks 1 and 2 has been rated 'positive' or 'insert' easy insertion and removal of lenses in the mirror when I saw the 'red eye' negative 'rating in 18 patients (45 %), in 2 shown in 14 patients (35%) as a 'negative' rating over time, depending on the awareness hyperemia has been reduced could see. Future lens purchases from doctors' Week 1 at the 2nd week, came as a result of the positive> negative evaluation was positive = negative. Rating, but usually more than 1 week, 2 weeks, 26 patients (65%) showed no change. State upon insertion of sight, wearing period increased dryness and showed a more positive assessment, the Comfort showed similar ratings. Somewhat negative assessment upon removal of vision status, comfort, dryness, day-to-day life at present, but in both state vision, comfort, dryness positive assessment appears worn than when a positive evaluation appears was unknown.

본 연구에서는 실내 쾌적성을 향상시키는데 적합한 에어컨의 기류형태를 파악하고자 세 가지 유형의 기류(감성기류, 풍량변화 기류, 풍향변화 기류)애 대한 감각반응, 감성반응, 정서반응 둥을 측정, 비교하였다. 기류감을 나타내는 13개의 형용사 쌍으로 구성된 의미미분척도에 대한 실험참가자의 평정을 변량분석한 결과, 감성기류가 다른 종류의 바람보다 선호되는 것으로 나타났으며, 간접적이고 신선하며 편안한 바람으로 평가되었다. 반면 풍량변화 기류는 가장 선호되지 않았으며, 직접적이고 거칠며 자극적인 바람으로 평가되었다. 정서반응에 대한 감각반응의 예측정도를 알아보기 위해 회귀분석을 실시한 결과, 변화가 없는 규칙적인 바람으로 평가되는 바람과 간접적인 바람을 쾌적하다고 느끼고 선호하는 것으로 나타났다. 감성반응에 영향을 주는 감각반응으로는 직접감이 단연 중요한 요인으로, 바람이 간접적으로 불어 온다고 판단될수록 이완되고 편안하다고 느끼며, 자연스럽고 부드러운 바람이라고 느끼는 것으로 나타났다

Purpose: This study is a non-equilibrium control-like experimental study that attempts to develop a nursing intervention plan and to present basic data by grasping the effect of the heating therapy nursing intervention program on patients entering the recovery room after surgery. Method: The subjects of the study were 31 in an experimental group and 31 in a control group who applied one heating therapy program located in D city. The warming therapy was conducted in a recovery room in the range of 38 to 43℃ through a heater. The general characteristics of the subjects were determined by real number and percentage, and a homogeneity test between the experimental group and the control group was determined by 𝑥²-test and independent t-test. The difference in body temperature, pain, and tremor over time between the two groups was determined by repeated measure ANOVA. Results: First, the results of repeated measurements immediately after surgery showed significant differences in body temperature, pain, and tremor between the two groups. Second, temperature comfort showed a significant difference. Conclusion: The results confirmed that there was a positive effect on the patient in the intervention of warming therapy after surgery.

산업의 발전과 함께 소비3자의 욕구는 제품의 질적, 감성적 향상을 요구하고 있으며, 또한 최근 각종 공학의 눈부신 발전에 힘입어서 자동차의 성능, 안락성 등이 크게 향상되면서 운전자의 운전 중 피로감 제거에 관심이 높아지고 있다. 본 연구는 주관적인 피로감 평가 방식 중 졸림감(KSS), 피로감 용어 및 신체 불편도를 이용하여 평가를 수행하였다. 졸림감 및 피로감 용어는 차종 및 자세에 따라 약간의 차이가 있었지만, 대체적으로 시간이 지남에 따라 불편함의 정도가 심해졌다. 신체 불편도에 대한 평가결과 엉덩이, 요추, 어때, 좌우 발목 부위가 불편한 것으로 나타났다. 이러한 결과들은 차종별 또는 운전자세에 따라 통계적으로 유의한 차이를 보이기도 했다. 이러한 연구 결과를 통해서 동환경 시스템의 기초 데이터를 확보할 뿐만 아니라, 자동차를 설계하는데 있어, 보다 안락하고 편안한 운전환경을 만들 수 있는 기초자료로써 활용이 가능할 것이다.
