The purpose of this study is to analyze the effect of the elderly"s preparation for old age on successful aging, and to investigate the mediating effect of self-efficacy and social participation. To verify this, the fit of the model and the significance of the mediating effect were verified by using the SPSS 23 and AMOS 23.0 statistical package programs for the analysis data answered by 447 elderly people over the age of 60. The results of the study were first, that the measurement variables of preparation for old age, self-efficacy, social participation, and successful aging were statistically positively correlated. Second, old-age preparation was statistically significant on self-efficacy and social participation activities, economic preparation for old-age preparation had a significant effect on the social aspect of successful aging, and social support of old-age preparation had a significant effect on the emotional aspect of successful aging. Third, the self-efficacy of the elderly was found to have a significant effect on social participation, and the self-efficacy and social participation of the elderly had a significant effect on all factors of successful aging. Fourth, it was found that self-efficacy and social participation had a mediating effect in the relationship between preparation for old age and successful aging. Based on these results, this study presented directions for various social participation activities such as economic activities that promote successful old-age life and suggestions for follow-up studies.

골격성 Ⅲ급 부정교합 환자에서 술전 교정전 예측치와 교정후 실측치의 차이에 관한 연구

황충주,권희정 대한치과교정학회 2003 대한치과교정학회지 Vol.33 No.1

본 연구에서는, 술전 교정전 예측전와 교정후 실측치 사이에 나타나는 오차의 크기와 정확성 및 어떠한 요소가 그러한 결과에 영향을 미치는가에 대해 평가하고자 하였다. 연세대학교 치과병원 교정과에서 골격성 Ⅲ급 부정교합ㅇ로 진단되어 술전 교정치료 및 양악수술을 받은 환자 가운데 조건에 부합되는 45명(남자 17명, 여자 28명)을 선별하여, 초진 상태를 T1, 교정 치료전 예측치를 T2, 술전 교정후를 T3로 정의하고 각각의 계측치를 수평과 수직좌표로 나누어 측정하였다. 또한 환자의 어떠한 진단적 요소가 술전교정의 예측치와 실측치 사이의 차이에 영향을 미치는지 알아보기 위해 연구대상을 arch length discrepancy (ALD), 상·하악 전치의 치축(U1 to SN, IMPA), curve of Epee(COS), 발치 여부, 발치한 치아의 종류 등에 의해 여러 군으로 분류하여 유의성을 평가하였으며 다음과 강은 결과를 얻었다. 1. U6mbc, L1x의 수평 좌표와 Uli, Ulx, U6me, U6mbc, L6mbc의 수직 좌표에서 예측한 위치와 수술직전의 실제 위치의 차이가 유의성(p<0.05) 있게 나타났다. 2. 예측의 정확성은 수평적인 차이의 예측에 있어서 수직적인 차이의 예측에 비해 상대적으로 높게 나타났다. 3. 하악에서보다 상악의 많은 계측점에서 예측치와 실측치 사이의 유의한 차이(p<0.05)가 관찰되었다. 4. 상악의 경우 발치 여부 및 발치한 치아의 종류, ALD의 양에 따라 상악 전치와 제1대구 위치의 예측에 유의한 차이(p<0.05)를 보였으며, 하악의 경우에는 ALD의 양과 IMPA에 따라 하악 전치와 제1대구의 위치의 예측에 유의한 차이(p<0.05)를 나타냈다. 이번 연구에서 얻은 결과를 통하여 술전 교정전 예측치와 실측치 사이의 오차의 정도와 그것에 영향을 미치는 요소들을 분석하고 희귀 계수를 구함으로써, 악교정 수술을 동반한 교정 환자의 치료 계획 시 예측의 정확성을 높일 수 있을 것으로 생각된다. 또한 수직적인 예측에 있어서는 앞으로 더 많은 연구가 이루어져야 할 것으로 생각된다. The Purpose of this study was to find out and evaluate discrepancies between preoorthodontic prediction values and actual postorthodontic values and factors contributing to it 45 patients(17 male, 28 female) who were diagnosed as skeletal Class Ⅲ malocclusion and received presurgical orthodontic treatment and orthognathic surgery at Yonsei university dental hospital. Lateral cephalograms were analyzed at oretreatment(T1), orthodontic prediction(T2), immediately before surgery(T3) and designated the landmark as coordinates of X and Y axes. The samples were divided according to ALD, upper and lower incisor inclination(U1 to SN, IMPA), COS, extraction, the position of extracted teeth and the statistical significance was tested to find out the factors contributing to the prediction. The results were as follows : 1. Differences between preorthodontic prediction values and actual postorthodontic values(T2-T3) were statistically significant(p<0.05) in the x coordinates of U6mbc, L1x and in y coordinates of U1i, Ulx, U6me, U6mbc, L6mbc 2. The accuracy of prediction is relatively higher in horizontal changes compared to vertical changes. 3. The statistical significance(p<0.05) between prediction and actual values is observed more in the landmarks of the maxilla than the mandible. 4. differences between prediction and actual values of incisor and first molar were statistically significant(p<0.05) according to extraction vs non-extraction, extraction type, ALD in the maxilla and according to ALD< IMPA in the mandible. Discrepancies between preorthodontic prediction values and actual postorthodontic values and factors contributing to the prediction must be considered in treatment planning of Cl Ⅲ surgical patients to increase the accuracy of prediction. Furthermore future investigations are needed on the prediction of vertical changes.

農民所得增大를 위한 고구마의 栽培와 利用에 관한 硏究

黃鍾奎,梁熙天,崔定植,權涌周 全北大學校 1977 論文集 Vol.19 No.-

New varieties of sweet potato Sinmi and Hwangmi were cultivated in the reclaimed hilly area of four kinds of soil series in Jeonbug province and their growth conditions such as cutting time, row spacing, application of fertilizers and plant growth regulators and covering effect were investigated. Besides these studies on cultivation of sweet potatoes, experiments on the change of chemical components of sweet potato tubers, adaptibility for storage and drying of sliced sweet potato tubers were carried out. The results are summarized as follows : 1. The early cutting of May 20, alley of 90 X 20cm, application of potassium(28kg/10a)and covering produced the high yield of sweet potatoes. The apllication of OED green did not increase the yield of sweet potatoes, 2. The yield of Hwangmi was higher than that of Sinmi. These two varieties of sweet potatoes grew well in all the test soil series except Bansan. By early cutting of May 20, the highest yield of Hwangmi was obtained in Songjung series soil and the highest yield of Sinmi was in Yesan. 3. Starch content was higher in Sinmi than in Hwangmi while yield of starch per unit area was high in Hwangmi because of its high yield of sweet potato tubers. Both Hwangmi and Sinmi showed very high water content of more than 70 per cent. The highest yield of total solid matter from Sinmi was on September 15 and that from Hwangmi on September 30. Sinmi and Hwangmi harvested on September 30 showed the highest starch content. 4. Variation in water content, starch, soluble sugar, protein and fat content during storage was minimum in the sweet potatoes stored in the temperature controlled storage chamber and was maximum in those stored in the cave under ground. As a result, percent of grade A sweet potatoes remaining was highest in the temperature controlled storage chamber and lowest in the cave under ground. 5. Hwangmi was more susceptible to Rhizopus nigricans than Sinmmi, especially under the humid condition. 6. Shape and thickness of slice did not affect the yield of dried sweet potatoes but affected the time needed for drying. Depending on the thickness and the shape of slice, variations of 36 hours and 12 hours in drying time were observed respectively. Drying table was most effective in drying of sweet potatoes and drying rack was also effective and required 2 days less time than mat. Dipping in water did not show any effect on drying time but improved the color of dried sweet potatoes.

섬모상 담체에 부착/ 생장하는 질산화 미생물의 Fluorescence in situ Hybridization에 의한 동정

황선진,장주희,장현섭 대한상하수도학회 2003 상하수도학회지 Vol.17 No.6

FISH (Fluorescence in situ Hybridization) technique was applied to the several nitrifiers in the bulk solution and on the Cilium media to promote nitrification process. It was confirmed by the results of Nso190 and NEU image analysis that ammonia oxidizer forms 'cluster' when they appears in both bulk and media. Another significant fact was that lots of microbial flocs were observed on the surface of the Cilium media substratum instead of biofilm. And from the results of NEU, it was known that Nitrosomonas europaea, Nitrosomonas eutopha and Nitrococcus mobilis or one or two of these three were the dominant ammonia oxidizers. The fact that no Nitrobacter sp. was detected with NIT3 probe means naturally that nitrite oxidizer in the nitrification reactor was not composed of Nitrobacter sp. but with other nitrite oxidizers like Nitrospira sp. etc. In order to detect these nitrite oxidizers, suitable probes must be tested.

정선주,정희연,황정민 대한소아청소년정신의학회 2001 소아청소년정신의학 Vol.12 No.1

연구목적 : 본 연구는 일과성 틱 장애(Transient tic disorder : TTD), 만성 틱 장애(chronic tic disoder : CTD), 뚜렛 장애(Tourette's disorder TD) 아동의 임상 양상을 비교하고, 틱 장애의 질환 심각도와 연관된 변인을 알아보기 위해 시행되었다. 방법 : DSM-IV 진단분류에 따라 틱 장애로 진단된 69명의 아동과 대조군 43명을 대상으로 인구학적 변인 및 틱과 관련된 임상적 변인을 조사하였다. 틱 증상의 심각도를 알아보기 위해 예일 틱 증상 평가 척도(Yale Global Tic Serverity Scale)을 시행하였으며 연구 대상 모두에게 동반된 정서/행동 문제를 평가하기 인해 아동 행동조사표(Child Behavior Checklist)를 시행하였다. 결과 : TTD군은 CTD및 TD군과 비교할 때 틱 증상의 지속 기간이 짧을 뿐 아니라 틱 증상의 심각도와 장해 정도도 미약하였다. TTD군의 동반된 정서/행동 문제 역시 CTD, TD군에 비해 유의하게 적었으며 공격성 소척도 점수를 제외하고는 정상대조군과 차이가 없었다. CTD군과 TD군간에는 틱 증상의 종류, 개수와 CBCL의 사회성 문제 소척도 점수외에는 통계적으로 유의한 차이를 나타내는 변인이 없었다. 틱 증상으로 인한 장해 정도를 가장 잘 예측해 주는 변인은 운동틱의 강도와 방해도, 틱 증상의 지속기간이었으며, CBCL 총 문제행동 점수와 가장 높은 연관성이 있는 변인은 주의력결핍/과잉운동장애(Attention deficit hyperactivity disorder : ADHD) 의 존재여부였다. 결론 : 본 연구의 곁과는 틱 증상의 심각도 외에 증상의 지속 기간이 틱 장애 아동들의 틱으로 인한 장해도에 큰 영향을 미치며, 동반된 ADHD의 존재가 이득의 임상상을 결정하는 데 있어 중요한 역할을 한다는 점을 시사한다. 또한 위와 같은 임상 변인들이 틱 장애의 진단적 분류보다도 틱 장애 아동의 질환 심각도를 판단하고 치료방침을 결정하는데 있어 더욱 중요함을 시사한다. 중심 단어 : 틱 장애 · 하위 진단 · 질환 심각도 · 장해. Objective : The purpose of this study was to compare the clinical features of children with three sub-diagnoses of tic disorder (transient tic disorder (TTD) , chronic tic disorder (CTD) and Tourette's disorder (TD)) and to exam the factors related with illness severity of them. Method : Subjects were 69 children who met DSM-Ⅳ criteria for tic disorder and 43 control chil-dren. All subjects were investigated demographic and clinical factors related to tic. The severity of tic was assessed with the Yale Global Tic Severity Scale (YGTSS) in tic disorder children. The Child Behavior Checklist (CBCL) was accomplished by parents of all subjects. Results : Children with TTD had not only shorter duration of tic symtoms but also milder tic severity and impairment than those with CTD and TD. They also had significantly lower scores on most CBCL subscales than children with CTD and TD, while they were similar with controls in all the CBCL subcale scores except aggressive behavior. Children with CTD and those with TD were similar to each other in clinical variables except number of tic symptom and scores on CBCL social problem subscale. The interference and intensity of motor tic symptoms and duration of tic symptoms were significant predictors of global impairment score on YGTSS, while the presence of comorbid ADHD was a pre-ictor of the total behavior problem score of CBCL. Conclusion : These findings indicate that duration of tic symptoms and the presence of comorbid ADHD as well as the severity of tic symptoms strongly associated with the illness severity of children with tic disorder. These results also suggest that those clinical factors may be more important for assessing the severity of illness and determining the treatment strategy than the sub-diagnosis itself in children with tic disorder. KEY WORDS : Tic disorder ㆍ Sub-diagnosis ㆍ Illness severity ㆍ Impairment.

Fractal coding is a promising method for image compression, but it has not lived up to its promise as low bit-rate image compression scheme. The existing algorithms for finding self-mapping contractive transforms are computationally expensive and offer a poor rate-quality tradeoff. In this paper, we propose a segment based fractal coding. We classify the range blocks into shade, midrange or edge blocks, and segment edge block along the edge. And we apply midrange coding scheme for each segment. Our experiments show that our method gives better rate-qualty trade of than current fractal block coding methods.
