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.

1. The change of MDA in accordance with exercise Many researchers at home and abroad told that MDA concentration tends to be low significantly if we do regular exercise in the long term. This means the adaptation of defence mechanism of antioxidants caused by moderate exercise. 2. The change of SOD, GPx, and CAT in accordance with exercise. The increase of SOD will be expected if a regular exercise in the long term is implemented regardless of a type, intensity, and time of the exercise. Meanwhile, at preceding researches, CAT showed significant change in high intensity exercise. It seems that GPx is significant when high intensity exercise is done and it is more activated by long-term and long-time exercise. 3. An intake of antioxidants and the change of SOD, GPx, and CAT in accordance with exercise It is reported that an intake and exercise of Vitamin C and E enhances resistiveness against lipid peroxide, and endurance exercise capacity significantly in many researches. Also, an intake of antioxidants and exercise do not have an effect on the activation of SOD through an intake of Vitamin, but high intensity exercise and an intake of Vitamin enhance the activation of SOD, and CAT. 4. The change of immune system in accordance with exercise and an intake of antioxidants It is reported that an intake of antioxidants and exercise have an effect on immune system. It is also reported that the medium intensity exercise enhances the increase of immune system, but high intensity exercise enhances the long-term increase of it. Meanwhile, if the period for an intake of antioxidants is short, antioxidants do not affect immune system. Also, independent treatments of antioxidant vitamins is limited about the improvement of immune function. 5. Suggestions The excessive exercise increases antioxidant enzymes like SOD, CAT, and GPx in skeletal muscles, heart, and livers. The threshold value and magnitude of exercise are different in accordance with enzymes and tissues. The validity of these findings are recognized by studying the response of free oxygen radicals in various tissues. However, mechanism that antioxidant enzymes are activated in short term during exercise is not acknowledged so it may be necessary that a research should be implemented about how the quick activation of antioxidant enzymes effectively responds to a cell damage from peroxide lipid. Also, the treatment of antioxidant vitamins enhances the activation of antioxidant enzymes and immune function, but a research about proper intake and period of antioxidant vitamins in addition to exercise in order to block the oxidative damage is necessary in the following research. Meanwhile, Methionine is the essential amino acids for growth and maintenance of cellular tissues. Jo Soo Yeal(1997) reported that an intake of Methionine improved the activation of SOD significantly. It is also reported that sulfhydryl group, one of metabolites of Methionine, acts as a direct remover of free radical, maintains Glutathione concentration constantly, and works as the disposition of glutathione peroxidase to protect cells from lipid peroxidation.(Shwa, et al., 1981) Methionine is the essential amino acids to protect cells from the reactive oxygen as a role of antioxidants. Until now, comparative studies about Methionine and existing antioxidants in relation to exercise have not been sufficient. Therefore, it may be meaningful that the effect on Methionine and existing antioxidants in relation to the relation of exercise and antioxidant enzymes in the following research.

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.

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.

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.
