본 논문에서는 안경식 스테레오스코픽 3DTV에 대한 효율적인 주관적 화질평가 방법에 대한 논의를 한다. 3DTV의 주관적 화질평가는 시각피로나 신체적 불편감을 유발하는 요인들을 규명하고 평가하여 사용자가3D 영상물을 관람할 때 이들을 최소화하면서 컨텐츠 제공자가 의도한 입체 깊이를 시청자가 지각 할 수 있도록 도와 줄 수 있도록 가이드라인을 제공하기 위해 이루어진다. 주관적 화질평가를 위해 적절한 깊이감을 갖는 카메라기반의 실영상과 컴퓨터 그래픽 기반의 3D컨텐츠를 사용하였다. 설문은 디스플레이 자체와 3D컨텐츠에 대한 화질평가 구분을 하고, 전문가와 일반인들을 대상으로 이루어졌다. 주관적 평가에 앞서 평가결과에 대한 객관성을 유지하기 위해 Random-dot Stereogram을 이용하여 개인별 입체시 평가를 하였다. 일반인들의 경우 전문가들에 비해 상대적으로 응답편차가 많이 발생하였으나 전문가 집단과 일반인 집단의 설문응답 경향은 대체적으로 일치하였다. 전문가 그룹의 주관적 평가 결과를 적절히 반영하고 일반인들의 응답편차를 줄임으로써 3DTV에 대한 주관적 평가에 대한 시간과 비용을 효율적으로 줄일 수 있을 것으로 기대된다.

This study investigates gender differences in cold perceptions and wearing behaviors for cold adaptation. A questionnaire composed of items on cold perceptions, intentions toward wearing additional clothing, and clothing for outdoor environments, among others, was used. Each item in the survey targeted 260 male (MS) and female (FS) college students evaluated using a five-point Likert-type scale. Data were statistically analyzed using the independent sample t-test and correlations. Main results can be summarized as follows: MS subjects showed lower dependence on the thermal insulation of clothing because they felt less cold and had the better ability to cope with cold. MS subjects had higher dependence on underwear during cold seasons, and FS subjects tended to wear heavier clothing to compensate for their cold feet with insufficient insulation. In addition, it was preferable to estimate thermal effects of actual wear by taking into account gender differences in the physique. The study is limited in that the room temperature and the actual amount of clothing were not measured, which offers an avenue for future research.

Purpose: The purpose of this study was to identify effects of a self-management program on symptom and functional status, health perception, and quality of life(QOL) of patients with CHF. Methods: Patients with CHF as defined through clinical judgment using the Framingham criteria and EF<50% were enrolled in the study (experimental: 21, control: 20). The symptom focused self-management program consisted of coping behaviors for symptoms including dyspnea, chest discomfort/pain, dizziness, ankle edema, and basic self-management including medications, diets, activity, lifestyle changes. Experimental group received an educational booklet after survey, and periodic telephone follow-up by a trained nurse. Data were collected the 3rd day after admission and at 1 month, 3 months, and 6 months after discharge using questionnaires. Results: Significant differences were found in the presence of symptoms, health perception, and QOL between groups during follow-up. Although no significant difference was found in functional status, the experimental group reported better functional status than the control group. Conclusion: By facilitating self-management of CHF using tailored interventions including education programs and telephone monitoring, it is expected that patients will be able to monitor their symptoms routinely, adhere to therapeutic regimen, and have a better QOL.

Background: The purpose of this study was to find out the effect of trunk stabilization training on the self posture control efficacy, physical self-description and perception stress in high school students. Methods: 92 voluntary students (73 females, 19 males) participated in this study. They received trunk stabilization training for 40 minutes per day and a time per week during 6 weeks period. Trunk stabilization training was an approach of education in proper posture and coordination of movement. In the evaluation, the self posture control efficacy scale (SPCES) was used to measure the posture control efficacy, the physical self-description questionnaire (PSDQ) was used to measure the physical self description and the perception stress scale (PSS) was used to measure the stress. All measurement of each subject were measured before and after stabilization training. Results: The SPCES were significantly different before and after (p<.05). The PSDQ and PSS were no significantly different before and after (p>.05) but the means were increased slightly. Conclusion: Conclusionally these results suggest that the trunk stabilization training increased the self posture control efficacy and would give help to control Students themselves.

This study investigates the effect of verbal and nonverbal communication on customer emotions and service quality perceptions. The subjects used in this study were customers of a fashion shop in Sunchon South Korea. The questionnaires were conveniently sampled from July 2010 to August, 2010. Questionnaire data from 335 customers of a national brand were analyzed through a reliability analysis, factor analysis, and multiple regression analysis. The results of this study are as follows. First, it was found that the verbal communication of service providers have a significant impact on customer emotion. Second postures/proxemics and physical appearance/paralanguage (out of 3 factors of nonverbal communication) have significant (+) influences on the positive emotion of customers and kinesics have significant (-) effects on the negative emotion of customers. Third, the verbal communication of service providers has a considerable impact on customer service quality perceptions. Forth, given the relationship between non-verbal communication and service quality, it was represented that all factors (postures/proxemics, physical appearance/paralanguage, and kinesics) of nonverbal communication, have significant positive influences upon customer service quality perceptions. Fifth, it was found that customer emotions have a significant impact on customer service quality perceptions.

Ceaseless studies and efforts to verify today's Korean nature that has advanced into digital era of 21C are continued. At this point of time, it is required to look back our heritage in diverse points of view free from theoretical and formal studies on our traditional spaces. Phenomenology, which is rising as the important theme in recent modem Western philosophy, suggests interesting analyses from this standpoint. This study is intended to analyze Korea's traditional residents 'Dok Rak Dang' based on Marleau-Ponty's phenomenology, and explore phenomenological spatial principle and new point of view implied in it. Particularly, Marleau-Ponty's phenomenology is the philosophy that shows intersubjective and involved relations between space and human, and intended to accept coincidental incidents occurred by human's action truthfully as they are. With three spatial concepts of direction, depth, and movement in Ponty's phenomenology, and placement nature of the earth that intercombine with human's body who is subject of these three concepts as analyze tool, Korea's traditional residents, 'Dok Rak Dang' has been analyzed. More segmentalized analyses have been deduced, and principle of phenomenology, that perceptions such as direction, depth, movement, etc are working synthetically to be accepted as essence of experiences could also be found in Dok Rak Dang.
