Objectives : This study tried to examine whether there is any difference between the middle-aged men and women in terms of the effect of health-related and oral health-related characteristics on their depressive symptoms (PHQ-9). Methods : We used the 2nd year data of the 6th session of the National Health and Nutrition Survey of 2,008 adults(aged40~64 years) for fulfilling the research objectives. Results : The analysis showed that among middle-aged male and female respondents, household income, subjective health conditions, and stress perception among health-related characteristics had common elements affecting their depressive symptoms. The self-reported oral health conditions affected depressive symptoms for male respondents. On the other hand, chewing problems and contraction of periodontal disease affected depressive symptoms of female respondents. Conclusions : Thus, it is necessary to consider the effect of sex in the relationship between health-related and oral health-related characteristics, and to make efforts to develop differential programs to manage and prevent depressive symptoms among men and women.

Purpose: This study sought to investigate the perceptions and service needs of tele-physical therapy among people in their 50s and older in Korea. Methods: Subjects were inducted during a 14-day survey of 104 people over the age of 50 in Korea and were administered a questionnaire consisting of 14 questions about their general characteristics and another 14 questions about tele-physical therapy. Results: The general characteristics of the participants (participants' gender, whether they were single or married, number of cohabiting families, final education, major, job, physical therapy experience, tele-physical therapy experience, presence of a physical therapy worker among relatives, subjective health awareness, chronic disease conditions if any, frequency of drinking, and smoking) were investigated. Among the perceptions of the subjects about tele-physical therapy, the score of 'awareness' was the lowest, and that of 'resolving restrictions on hospital visits' was the highest. In an analysis of the correlation between perceptions and needs, there was a significant correlation with factors other than 'awareness' and 'information protection' factors. The regression analysis of necessity and factors revealed that the awareness of necessity increased as the intention to use, health improvement, and time efficiency improved. Conclusion: These findings presented the perception and necessity of tele-physical therapy for adults in their 50s or older in Korea. These results will help confirm the demand for tele-physical therapy in this age group in Korea and the need to improve the available physical therapy services.

Purpose: Patients with brain damage suffer from limitations in performing the activities of daily living (ADL) because of their motor function and visual perception impairment. The aim of this study was to help improve the motor function and visual perception ability of patients with brain damage by providing them with virtual reality-based contents. The usability results of the patients and specialists group were also evaluated. Methods: The ADL contents consisted of living room, kitchen, veranda, and convenience store, similar to a real home environment, and these were organized by a rehabilitation specialist (e.g., neurologist, physiotherapist, and occupational therapist). The contents consisted of tasks, such as turning on the living room lights, organizing the drawers, organizing the kitchen, watering the plants on the veranda, and buying products at convenience stores. To evaluate the usability of the virtual reality-based visual cognitive rehabilitation service, general elderly subjects (n=11), stroke patients (n=7), stroke patients with visual impairment (n=4), and rehabilitation specialists (n=11) were selected. The questionnaires were distributed to the subjects who were using the service, and the subjective satisfaction of individual users was obtained as data. The data were analyzed using SPSS 21.0 software. The general characteristics of the users and the evaluation scores of the experts were analyzed using descriptive statistics. Results: The usability test result of this study showed that the mean value of the questionnaire related to content understanding and difficulty was high, between 4-5 points. Conclusion: The virtual reality rehabilitation service of this study is an efficient service that can improve the function, interest, and motivation of stroke patients.

음성 신호의 효과적인 양자화를 위해서 인간의 청각 인지 특성을 이용하는 방법이 널리 사용되고 있다. 그러나 아직까지는 음성 스펙트럼의 크기 정보에 대한 인지 특성만을 이용하고 있을 뿐, 음성의 위상 정보는 그 중요성에 비해 간과되어 온 것이 사실이다. 본 논문에서는, 음향 신호로부터 청각 인지 측면에서 관련 없는 위상 성분을 추정하는 PIPE(Perceptually Irrelevant Phase Elimination) 방법을 제안하였다. 제안된 방법은 청각 특성이 critical band 대역 내의 상대적인 위상 관계에 민감하다는 관측 결과에 근거하여, 일반적인 stationary 푸리에(Fourier) 신호와 고조파(harmonic) 신호에 대해 각각 인지 측면에서 관련 없는 위상을 판별하는 방법을 제공한다. 제안된 방법을 음성 분석-합성(analysis / synthesis) 시스템에 적용함으로써 일부 위상 정보만을 이용해 음성을 복원하였으며, 청취 실험 결과 제안된 방법의 효율성을 알 수 있었다.

본 논문에서는 인간의 시각 인지 특성을 고려한 새로운 객관적 화질평가 방법을 제안하였다. 인간에 의한 화질 평가는 최종적으로 시각 피질내에 있는 세포의 수용계 반응으로부터 얻어진다는 점과 인간의 시각은 한번에 영상 전체의 왜곡에 대한 반응을 일으킬 수 없음을 고려하여 입력 영상을 부 블록으로 분할하고, 시각 피질 내의 수용계와 가장 잘 부합되는 Gabor 함수를 이용하여 필터 뱅크를 구성하여 부 블록에서 지역적 왜곡 정도를 측정하고, 이를 이용하여 전역적 왜곡 정도가 계산 되어 진다. 제안된 방법은 VQEG에서 제공하는 화질 평가용 영상을 이용하여 평가 되었으며, 주관적 화질 평가와 높은 상관관계를 갖는 객관적 화질 평가 모델임을 실험 결과에서 보여준다.

Purpose: The specific aims of this study was to find out the barrier to smoking cessation intervention in clinical practice among clinical nurses and compare them in high barrier group with those in the low barrier group. Method: The sample of this study consisted of 738 nurses practicing in general hospitals with over 400 beds throughout the country. The questionnaire was adopted from the 'Oncology Nurse's Tobacco Control Survey' used in the United Stated by Sarna et al.(2001). Result: Age, marital status, hospital experience, position were the variables related to the mean score of subjective resource insufficiency. The perception that the patient was not motivated to quit smoking was the most commonly identified barrier in low barrier group and the second most common barrier in high barrier group. Conclusion: Younger, with less clinical experience, single, staff nurses were the characteristics of nurses in the high barrier group. The smoking cessation educational program should be targeted to these populations. Further research is needed to develope strategies to reduce the perception associated with barriers in delivery of tobacco cessation interventions.

A study was done to identify the differences of women's perception of fatigue according to the period of pregnancy. Questionnaires were collected from 510 normal pregnant women in 3 University Hospitals in Korea from April to November of 1999. The questionnaires used to measure pregnant women's fatigue were the "Subjective Symptoms of Fatigue Test" designed by the Research Committee of Industrial Fatigue in Hygienic Association of Japanese Industry. The collected data was analyzed by SPSS-Win. The results revealed that there was a significant difference according to the periods of pregnancy: The degree of fatigue was the highest in the first trimester and then third and second trimester in decreasing order (F=89.53, p=0.000). The degree of fatigue was also compared with the respect to the general characteristics of women: There were statistically significant differences according to number of pregnancy (t=6.41, p=0.000), expectation of pregnancy (t=-291, p=0.004) and weight change (F=8.07, p=0.000). Therefore, variable nursing intervention should be provided to alleviate the fatigue according to the each trimester of pregnant period. Especially the nursing intervention program to alleviate the physical fatigue in the first trimester is necessary.

Image saliency detection is the basis of perceptual image processing, which is significant to subsequent image processing methods. Most saliency detection methods can detect only a single object with a high-contrast background, but they have no effect on the extraction of a salient object from images with complex low-contrast backgrounds. With the prior knowledge, this paper proposes a method for detecting salient objects by combining the boundary contrast map and the geodesics-like maps. This method can highlight the foreground uniformly and extract the salient objects efficiently in images with low-contrast backgrounds. The classical receiver operating characteristics (ROC) curve, which compares the salient map with the ground truth map, does not reflect the human perception. An ROC curve with distance (distance receiver operating characteristic, DROC) is proposed in this paper, which takes the ROC curve closer to the human subjective perception. Experiments on three benchmark datasets and three low-contrast image datasets, with four evaluation methods including DROC, show that on comparing the eight state-of-the-art approaches, the proposed approach performs well.
