  • 본 논문에서는 무안경식 다시점 입체 모니터에서 다시점 3차원 영상을 시청할 때 발생하는 시점 엘리어싱 (view aliasing) 및 시점간 엘리어싱(inter-perspective aliasing)을 제거하기 위해 변위 정보에 적응적인 필터를 제안한다. 일반적으로 다시점 영상의 해상도가 다시점 모니터의 해상도보다 크면 입력되는 다시점 영상의 부표본화(subsampling)로 인하여 시점 엘리어싱이 발생하게 된다. 또한 무안경식 다시점 모니터에서 관찰자가 영상을 시청할 때 시점 이동 시 불연속적인 구간으로 인해 발생하는 시점간 엘리어싱 때문에 눈의 피로를 느끼게 된다. 이러한 엘리어싱 현상은 입체 영상을 시청할 때에 변위 정보가 클수록 더욱 강하게 나타난다. 따라서 본 논문에서는 중간영상 생성 개수와 변위 정보의 강도에 따라 필터의 강도를 조절하는 저역통과 필터링 기법을 제안하였고, 제안한 필터링에 의해 엘리어싱의 영향이 줄어드는 효과를 DSCQS (double stimulus continuous quality scale method) 방식을 이용하여 실험을 통해 검증하였다.

  • The purpose of this study is to provide the basic data to improve the QOL in patients suffering from female cancers. Subjects of this study were consisted 255 persons who admitted or visited three university hospitals. The instruments used for this study included "the Quality Of Life Scale(QOL)" developed by National Conference on Cancer Nursing and successively amended by Kwon(1990), "Anger in" developed by Spielberger(1988) and successively amended by Chon(1997). The collected data were analyzed using a SPSS 11.0 for PC. To find out significant factors of Anger in & QOL in patients with Female Cancer patients, Frequency, Percentage, t-test, ANOVA, Scheffe-test, Pearson's correlation coefficients were conducted. The main findings : Anger in score was a little low & QOL score was middle. Several characteristics of the subjects were identified to differenti ate the "Anger in" and "QOL". Age status(F=2.64, p=0.05), education status(F=2.73, p=0.04), Health insurance(t=2.27, p=0.00) and cancer insurance status(t=2.97, p=0.00) was significant factors of the "Anger in". Education status(F=2.64 p=0.05), Occupation status (t=2.90, p=0.00), Monthly income (F=3.23 p=0.01), Stage of disease(F=9.23 p=0.00), Perceived health status(F=73.61 p=0.00), Perceived fatigue status(F=11.26 p=0.00) was significant factors of the "QOL". In conclusion, Anger in score was a little low & QOL sore was moderate. The degree of Anger in and quality of life were significantly negative correlated. Therefore, It is needed strategies for intervention of 'Anger in' to improve the QOL in female cancer patients. The significant characteristics of related to "anger in" & QOL should consider in sociopsychogical nursing intervention.

  • This report describes 173 formulas related to which are mainly used Paeoniae Radix in Dongeuibogam. The following conclusions were induced through investigations on the formulas that are used Paeoniae Radix as a main component. 1. We found the formulas in Dongeuibogam that Paeoniae Radix is used as a main ingredient in each prescriptions. 22 times(12.4%) of them are recorded in women's disease chapter, 20 times(11.3%) are in feces chapter, 14 times(7.9%) are in uterus, 12 times(6.8%) are in wind chapter, 10 times(5.6%) are in fatigue chapter, 9 times(5.1%) are in blood chapter, which are arranged in order of frequency. 2. Formulas that utilize Paeoniae Radix as the main ingredient are used in the treatment of women's disease, diarrhea, paralysis, yin and yang-deficiency syndrome. They are also used for treating 117 different types of diseases. 3. The dosage of Paeoniae Radix in formulas is from 1 don(nearly 3.75g) to 1 nyang 5 don (nearly 56.25g), however 1 don has been taken the most for clinical application. 4. Paeoniae Radix can make various effects with other ingredient, like fulfilling yin and blood, relaxing muscles and allaying pain. And this can be found in the formulas such as Samultang(四物湯), Jakyackgamchotang(芍藥甘草湯), Sambaektang(三白湯).

  • Jet lag can be defined as the cumulative physiological and psychological effects of rapid air travel across multiple time zone. The consequences of jet lag include fatigue, general malaise, sleep disturbances, and reductions of cognitive and psychomotor performance, all of which have been documented in experimental biological and air crew personnel studies. Thus authors tried to study the jet lag of natural travellers by modified self reporting sleep log. Total 61 healthy travellers was studied for 3 days before and 7 days after jet-flights across seven to ten time zone. The eastbound travelling group was 38 persons, aged 19 -70 and westbound travelling group was 23 persons, aged 13 - 69. Sleep onset time, wake-up time, sleep latency, awakening frequency on night sleep, awakening duration on night sleep, sleepiness at wake-up and nap length were evaluated. Our results suggested that the 7 to 10 time zone shift gave significant influence to traveller's sleep-wake cycles. The date which subjective physical condition was recovered on was $5.16{\pm}1.50$ day after arrivals for eastbound, while for westbound, $4.91{\pm}1.62$ day. In eastbound travelling, sleep onset time became later than baselines and could not recover until 7th day. But in westbound, it became earlier than baseline and could recover until 6th day. The mean score of 24-hour sleepiness was greater in eastboumd than westbound. Therefore the eastbound travelling caused more sleep-wake cycle disturbance and daytime dysfunction than westbound travelling. In other parameters, there was no definite difference between east and westbound. From our results, it was suggested that the symptom severity of jet lag was dependent on the travelling direction. To demonstrate more definite evidence, large sized data collections and comparision by age difference were needed.

  • Exercise is an important strategy for health promotion in patients having osteoarthritis. But, lots of patients with osteoarthritis were underexercised. Exercise pattern and influencing factors of exercise barrier are not well-known. To address this issue, we studied the exercise pattern and influencing factors of exercise barrier in patients with osteoarthritis. The subjects of the study were 463 adult osteoarthritis (Mean age = 61.63 years) who had diagnosed osteoarthritis by rheumatologist. Data were gathered from May 1999 to February 2000 using a questionnaire and exercise barrier(Sallis et al, 1989), exercise pattern(Lee et al., 2000), physical status by WOMAC(Bellamy, 1989), socail support(Sallis et al., 1989), fatigue and pain using graphic rating scale, depression by CES-D(Radloff,1977). Data were analyzed with the SPSS win 6.0 using frequency, ANOVA, Stepwise multiple regression. The results of this study were as follows; 1) 56.4% of sample was 'do not exercise at all', 'longer rest than exercise', was 15.9%, 'longer exercise than rest' was 7.2%, 'exercise regularly' was 20.5%. 2) Social support (F=10.349, p=0.000) and exercise barrier(F=4.455, p=0.004) were showed significantly difference by exercise pattern. 3) Influencing factors of exercise barrier were depression and social support. Thoses explained 13.3% of exercise barrier. In conclusion, half of osteoarthritis patient did not do exercise and it was shown that depression and social support were major influencing factors to exercise barrier. The results of this study can be applied to develop the health promoting educational program for patients with osteoarthritis.

  • This study was carried out to investigate consumption patterns of health functional foods (HFF) and analyze their related factors in male workers in order to provide basic data for appropriate understanding and optimal use of HFF. The subjects were 325 shipbuilding workers aged 20~50 in the Geoje area. About 84% of subjects reported that they were currently consuming or had experience of consuming HFF. The most commonly used type of HFF was vitamins (53.5%), followed by red ginseng (28.9%) and vegetable extract (15.4%). The major reasons for consuming and not-consuming HFF were 'to recovery from fatigue' (49.5%) and 'can not trust the effects' (39.4%), respectively. The intake period was 'less than 3 months' (35.5%), average monthly expense was 'less than 50,000 won' (49.1%), and purchase place was 'store of health functional foods' (32.2%) as the most common answers. The effects after consuming HFF were 'moderate' (51.3%) as the most common answer, and 16.1% of subjects experienced side effects, such as diarrhea, indigestion and nausea. Contributing factors for selecting and desire for future use of HFF were 'effectiveness' (52.2%) and 'when necessary' (67.8%) as the most common answers. Experience of using HFF was positively correlated with age (p<0.05), marital status (p<0.05), unbalanced diet (p<0.01), concern about health (p<0.05), and fear for disease (p<0.05). Purchase of HFF was positively correlated with fear of disease (p<0.01), whereas it was negatively correlated with frequency of exercise (p<0.05). The desire for future use of HFF was positively correlated with concern about health (p<0.05), fear of disease (p<0.01) and drinking (p<0.05). In conclusion, factors affecting consumption patterns of health functional foods (HFF) were age, marital status, unbalanced diet, concern about health, fear of disease and drinking.
