Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

This study was performed by questionnaire to investigate the recognition, preference and intake of calcium and related food behaviors of high school and college students (males 200, females 200) in the Daegu area. The daily intake was determined by a 24-hr dietary recall method. The results were summarized as follows: The recognition score of calcium of the subjects was male 10.46, female 11.54, respectively. Also the preference score of calcium source foods of the subjects was male 3.40, female 3.51. The students preferred yoghurt, ice cream, sweet potatoes and milk, in the order, but they disliked beans boiled in soysauce, sesame seeds and cheese. The frequency of calcium source foods were remarkably low. Milk products were the most preferred and eated calcium source food. A day's calcium intake was 54.1~61.1% of RDA for Koreans. The meal skipping, diet and nutrition consideration ratio of the subjects were 66.5, 13.3, 20.0% respectively. There was a significant positive correlation between the recognition and preference scores of calcium.

The goal of this study was to find the way of reduction on food waste in the university cafeteria. A survey was conducted on the 500 faculty members using Yeungnam University cafeteria, and if illustrates the faculty's use and perception for the reduction of food waste. Its results can be summarized as follows 32.0% of the total users use the university cafeteria everyday, also 86.6% of the users preferred Korean style dish. Female users left more food than the male users resulting in more food wastes. The male users resulting in more food waste and the most leaving food was Kimchi than the other types of foods. The most favorite stew and side dish turned out to be Yukgaejang and Bulgogi respectively, also Kimchibokkumbab was the preferred dish. But they disliked Sunjiguk, Ginger, Jellyfish and Mackerel pike. The perception of male users on the reduction of food waste was lower than that of female users. The best way of food waste treatment recognized by the users were utilizing the waste food as fodder for animals or fertilizer.

외상에 의한 치아의 함입은 치아가 치조골 방향으로 변위되어 있는 상태이다. 함입성 탈구는 다른 유형의 탈구성 손상에 비하여 드물게 발생하고, 낙상에 의한 경우가 많으며, 소녀보다는 소년에서 호발하는 것으로 보고되었다. 치아가 함입되었을 때, 치수괴사나 유착, 치근흡수, 근관폐쇄, 변연골 상실 등과 같은 합병증이 발생할 수 있으며, 치아 경조직과 치아 지지조직 등의 손상이 동반되는 경우가 흔하므로, 예후를 예측하고 정확한 진단 및 치료계획을 수립하는데 어려움이 있다. 함입된 치아의 치료는 자발적으로 재맹출하기를 기다리거나, 교정적 견인 또는 외과적으로 재위치 시키는 방법이 있다. 이 증례는 외상으로 인하여 상악 좌측 중절치가 함입되었다는 주소로 내원한 6세 7개월 된 여아에서, 함입된 치아의 자발적인 맹출을 기대하였으나 맹출이 되지 않아서, 교정적으로 견인하여 맹출시킨 경우로 양호한 결과를 얻었기에 이를 보고하는 바이다. Traumatic intrusion is a type of injury that involves axial displacement of a tooth toward the alveolar bone. Its occurance is relatively rare compared to other types of luxation in permanent dentition. It is more common in boys than in girls, and most common etiology of intrusion is fallen down. Various complication may occur following traumatic intrusion, such as pulp necrosis, root resorption, pulp obliteration and marginal bone loss. In addition, traumatic intrusion is commonly combined with hard or soft tissue injuries. Therefore, it is difficult to establish proper treatment plan. Choice of treatment for an intruded tooth by trauma include waiting for spontaneous re-eruption, orthodontic repositioning, and surgical repositioning. In this case, we repositioned the intruded central incisor using orthodontic traction, in a six-year old girl, which failed to re-erupt spontaneously.

완전탈구된 치아의 치료법은 재식술을 들 수 있는데, 이는 치조와에서 이탈된 치아를 가능한 빠른 시간 내에 재식립하는 술식이다. 일반적으로 재식술의 성공여부는 치수와 치주인대 손상의 정도, 치아상실 시부터 치조와 내로 재식될 때까지의 경과시간, 탈구된 치아의 보관 상태, 치근의 발육 정도 등에 좌우된다. 그 중 치아상실 시부터 재식까지의 경과시간이 특히 중요한데, 일반적으로 30분 이내에 재식을 시행한 경우에는 90%이상의 성공률을 보인 반면 30분에서 90분 사이에서는 43%, 90분 이상 경과 시에는 7%의 성공률을 보인다고 알려져 있다. 본 증례는 완전탈구 후 오랜 시간이 지연되어 재식을 시행하였으나 치근유착을 통해 비교적 양호한 임상적 결과를 얻었다. 이러한 치료로 결국은 치아의 손실이 일어날지라도, 이것은 환자 및 보호자의 사고에 따른 충격을 감소시켜주고, 자체로 공간 유지장치로서의 기능을 할 수 있으며, 발치에 따른 치조골의 흡수를 늦추는 한편, 적극적인 보철치료를 위한 시간을 벌어줄 수 있을 것으로 사료된다. Replantation may be treatment choice for a completely avulsed tooth caused by traumatic injury. The outcome of replantation depends on the following factors: minimal damage to pulp and periodontal membrane the length of time the avulsed tooth was out of the mouth, how the tooth was stored the level of root formation, etc. The time from the act of avulsion of the tooth to the actual replantation is especially important. Generally, when replanted within 30 minutes, more than 90% of cases succeed but when the time is between 30 to 90minutes 43% and greater than 90 minutes 7%. This is a case of a replanted tooth with relatively good prognois by ankylosis though there was a great time lapse since the tooth was avulsed. Though such treatment lead to loss of the tooth in case of children or adolescents this treatment is meaningful because it may earn time until any definitive therapy functionally stimulate the alveolar bone to retain its hight for a better prognosis for future treatment and act as space maintainer

Effects of acetic acid, malic acid and citric acid on copper dissolution from new and used copper saucepans at different concentrations (0, 0.02, 0.04, 0,1, 0.2, 0.4, 1,0, 2,0, 4.0%), different boiling times (0, 10, 20, 30, 40, 50, 60mins.), and different temperatures (5, 20, 40, 60, 80, 100%)were investigated. As acetic acid concentration increases, copper content increases. Copper dissolution concentration from copper saucepans at boiling in malic acid increases more than in acetic acid or citric acid, At above 60℃, as the temperature increases, the concentration of copper dissolved from copper saucepans also increases. As boiling time increases, the concentration of copper dissolved from copper saucepans also increases. In addition, through repeated use, the concentration of copper increases as well. And copper concentration dissolves in large amounts from used saucepans rather than new saucepans. The dissolution of copper with distilled water by repeated use does not dissolve at all. 1% acetic acid dissolves in large quantities.

The purpose of this study is to present quantitatively the influence of variables that had the largest effect on the changes in suspended solids(SS), which would cause turbid water phenomenon, among water quality factors of the non-point pollution source, and then to develop a multiple regression equation of SS and predict the water quality of ungaged watersheds so as to provide basic data to establish efficient management plans for SS which flow in rivers and lakes. To identify the correlation of SS with the amount of rainfall and the state of land use, a simple correlation analysis and a simple regression analysis were conducted respectively, Finally, a multiple regression analysis was conducted to provide that SS were set as dependent variables while the amount of rainfall, paddy fields and dry fields were set as independent variables. As a result, the amount of rainfall had the most significant influence on changes in SS, followed by dry fields and paddy fields. In addition, the multiple regression equation was developed to predict SS in unmeasurable watersheds.

This paper describes a nonlinear adaptive noise canceller(ANC) using neural networks as the nonlinear adaptive filter to make up for drawback of the conventional noise canceler with the linear adaptive filter. Performance of the proposed noise canceller is evaluated using both periodic and nonstationary signals contaminated with broadband noise, assuming that the noise of primary and reference inputs is uncorrelated. The proposed ANC is compared with the adaptive noise canceller of the linearfilter for the relative comparison of noise rejection performance. Experimental results show that the neural network based ANC outperforms the linear ANC with respect to mean square error, and the recurrent neural network adaptive filter performs the best. It is verified that the neural network adaptive filter, having highly nonlinear dynamics by virtue of the distributed nonlinearities, can be used as an effective adaptive filter for the rejection of broadband noise.
