knowledge, attitudes, and educational needs for sexuality of the elderly. Method: This was a descriptive study, in which data were collected from February to April 2002 from 354 elderly who were residing in Chung-Chung province. Result: 1. The level of knowledge regarding sexuality was below average. 2. The level of the attitudes toward sexuality of the elderly was neither positive nor negative. 3. The educational needs of the elderly were above average. 4. Higher level of knowledge on sexuality was significantly correlated with more positive attitudes and education needs for sexuality, and more positive attitudes toward sexuality was significantly correlated with more educational needs for sexuality. Conclusion: Particularly men, with good health, and those who were in intimate relationships with their spouses and still engaged with active sexual life showed somewhat higher level of knowledge and positive attitudes as well as higher educational needs. Therefore, further development and applying of sexuality promotion programs for healthy elder couples should be considered in the future to enhance the quality of life of elder population. In addition, it is also suggested to develop an alternative intervention program on sexuality for elderly who are women, those with meager health, and the bereaved.

한라산 혼파목초지에 있어서 억새 (Miscanthus sinensis)의 계절적 연차적 생육변화

조남기,김한림,고영희 제주대학교 1984 논문집 Vol.17 No.-

This study was conducted to examine the yearlv and seasonal changes of Miscanthus sinensis on the improved pasture of the mountain districts around Mt. Halla in Cheju Island. For this study, the researcher had investigated for six years from 1977 to 1982 the improved pasture which had been used for grazing from 1977 to 1982. The pasture was reclaimed from native grassland. The mixed seeds of 17 kgs' Dacrylis glomerata, 7 kgs' Festuca arundinacea, 2 kgs' Lolium multiflorum and 2 kgs' Trfolium repens were sowed per 1 ha. The results of this study are the following; 1. The seasonal changes of Miscanthus sinensis: its length, weight, density and coverage are heighest in Autumn, and are lowest in Spring every year. 2. The yearly change in the length of Miscanthus sinensis: its length is gradually increased from 46.19cm in the first year after the reclaimation to 58.81 cm in the 6th year. This change can be represented by the regression equation, y=1.10x^(2)+l.96x +44.02. 3. The yearly change in its density: its density is rapidly increased from 0.06% in the first year to 0.72% in the sixth year. The results of this change can be obtained with the regreuion equation, y=0.04x^(2)-0.11x + 0.07. 4. The yearly change in the coverage: its coverage is increased year by year from 0.34% in the first year to 5.67% in the sixth year. This change can be calculated with regression equation, y=0.18x^(2) + 0.12x-0.42. 5. The yearly change in its weight: the weight is also increased year after year from 7.98 kg in the first year after reclaimation to 130.04kg in the sixth year. This change can be calculated with the regression equation of y=5.88x^(2)-15.27x + 15.24.

本 硏究는 濟州道에서 燐酸施肥量差異가 靑刈豌豆의 主要 形質과 收量에 미치는 影響을 究明하기 위하여 濟州在來豌豆와 Sparkle을 供試하여 1998年 3月부터 5月까지 修行하였으며 試驗한 結果를 要約하면 다음과 같다. 1. 開花日數는 燐酸施肥量이 많아짐에 따라 늦어지는 傾向이었다. 品種問의 開花日數는 濟州在來豌豆가 빨랐고, Sparkle은 늦은 편이었다. 2. 草長은 燐酸施肥量이 많을수록 길었으며, 品種間에는 各 處理區에서 濟州在來豌豆가 길었고, Sparkle은 짧았다. 3. 莖直經, 主莖節數는 濟州在來豌豆 Sparkle 두 品種 供히 燐酸施肥量이 增加할수록 增加하였다. 4. 10a當 靑刈收量은 두 品種 모두 燐酸施肥量이 많아짐에 따라 漸次的으로 增加되는 傾向이었다. 5. 濟州求來談臺의 草長과 靑刈收量과는 高度로 有意한 正의 相關을, Sparkle은 正의 相關關係가 있어서 두 品種 모두가 草長이 길수록 靑刈收量이 많았다. Two pea cultivars, 'Cheju local pea' and 'Sparkle', were planted on 3 March at Cheju at 5 phosphate rates(0, 5, 10, 15, 20kg/10a) to determine the optimum phosphate fertilization rate. Days to flowering increased as phosphate rate was increased. Days to flowering of Cheju local pea was earlier than that of Sparkle. The more phosphate rate, the higher plant height Plant height of cultivar Cheju local pea was taller than of Sparkle. As phosphate rate was increased, stem diameter and number of nodes per plant of two cultivars increased. Fresh forage yield of two cultivars linearly increased as phosphate rate was increased from 0 to 20kg/10a. Plant height for each cultivar was positively correlated with fresh forage yield.

ABSTRACT Two pea cultivars, 'Cheju local pea' and 'Sparkle', were planted on 3 March at Cheju at 5 plant densities(10x 10, 15x15, 20x20, 25x25, 30x30cm) to determine the optimum plant population. Days to flowering decreased as planting density was increased. Days to flowering of Cheju local pea was greater than Sparkle that of. The broader planting density, the higher plant height. Cheju local pea was taller than Sparkle. As planting density increased, stem diameter and number of nodes per plant of two cultivars increased. Fresh forage yields of Cheju local pea (3,585kg/10a) and Sparkle(3.787kg/10a) were greatest at 10X 10cm planting. Plant height for each cultivar was positively correlated with fresh forage yield.

버섯의 갈변병 유발세균 P. tolaasii의 길항세균인 P. fluorescens의 분리 및 배지최적화

조남철,박범식,전억한 경희대학교 유전공학연구소 1991 遺傳工學論文集 Vol.3 No.-

버섯 갈변병 유발세균인 P. tolaasii에 길항성을 가진 P. fluorescens의 대량배양을 위하여 배지조성 및 배양의 최적조건을 확립하였다. 세포성장에 있어서 carbon 및 energy source인 glucose의 경우 30g/l일 때 세포농도가 가장 높았으며, yeast extract의 최적농도는 10g/l였다. 또한 균체의 구조합성에 있어 중요한 nitrogen source인 NH_(4)Cl과 (NH_(4))_(2)SO_(4)는 각각 1.0g/l와 0.1g/l일 때 세포성장이 가장 좋은 것으로 나타났고, sulfur source인 MgSO_(4)·7H_(2)O의 최적농도는 1.0g/l였다. 그리고 KH_(2)PO_(2)와 CaCl는 각각 1.0g/l와 0.1g/l일때 세포농도가 가장 좋았고, 온도 30℃, pH 6.0 그리고 초기 D.O가 68일 때 세포성장이 가장 높았으며, 균체 비증식속도(μ)와 생산성(P)도 높았다. P. fluorescens was studied in both batch and continuous culture in order to find out optimum conditions for cultivation. p. fluorescens is an aerobic bacteria and antagonistic to p. tolaasii which causes blotch disease on the mushroom cap. Cells of P. fluorescens were grown well on medium containing 30 g/ℓof glucose, whereas the growth was inhibited with the glucose concentration at higher than 30g/ℓ. The highest values of specific growth rate and productivities were obtained when using 10 g/ℓ of yease extract. Optimum concentrations of NH_(4)Cl and (NH_(4))_(2)SO_(4) for culture were found to be l.0g/ℓ and 0.1 g/ℓrespectively. The culture of MgS0_(4)·7H_(2)O was mostly about l.0g/ℓ as a sulfur source. It was also found that the cell concentrations were at the maximum level when grown on the medium containing l.0g/ℓ of KH_(2)PO_(4) and 0.lg/ℓ of CaCl_(2). Also, the optimum culture conditions were 30℃ and pH 6.0. Cultivation of P. fluorescens at high initial D.O value led to a decrease of bacterial productivity in batch culture. Maximum productivity was achieved at 68 for the initial D.O. value.

NTSC 비디오 신호에서 comb 필터링은 라인과 프레임 사이의 위상차를 이용하여 Y와 C를 분리하는 기술이다. comb 필터링의 가장 중요한 부분은 기준 라인을 가지고 가장 높은 상관관계를 가지는 라인을 찾는 것이다. 본 논문에서는 프레임 안에 라인 사이의 유사성을 계산하기 위해 움직임 추정과 웨이블릿 변환을 적용한 새로운3D Y/C 분리 방법을 제안한다 제안한 알고리즘을 comb 필터링에 적용하였을 때, 화질은 기존의 시간 영역의 3D comb 필터링보다 약 1~2dB 향상되었다. 차후 연구 과제로 NTSC 비디오 신호의 유사성 검출에 효율적인 웨이블릿을 찾는 것과 잡음에 대한 내성을 강화해야 하며 최종적으로 하드웨어로 구현하는 것이다.

한혜자,김남초 노인간호학회 2007 노인간호학회지 Vol.9 No.1

Purpose: The purpose of this study was to provide basic information for developing programs to maintain and improve the physical health of the elders living in rural areas. Methods: For this study, 200 male and female elders were selected through convenient sampling. The researchers visited the home of each elder and collected data by using the mini-nutritional assessment tool developed by Guigoz, Vellas & Garry (1996). Real numbers and percentages, means and standard deviations, t-test, ANOVA and Scheffe' test were used to analyze the data. SAS was the computer program used in this study. Results: For nutritional status, 57% of the subjects were well-nourished, 41%, at risk for malnutrition and 2%, under nutrition. However, the average score for nutritional status was satisfactory at 24.03 points. The nutritional status of the elders was different according to their gender and age. Nutritional status was better in men than in women and better for those their 60s compared to those their 70s or 80s. Conclusion: The nutritional status of elders in rural areas was assessed to be satisfactory; however, the nutritional status deteriorated as they got older. This result suggests the necessity of more thorough nutrition management for older elders by health care providers in rural areas.
