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.

Knowledge information society in 21st century emphasizes the social responsibility for the increase of welfare and public benefit so that the corresponding role has been expanded. Thus, the government is more obliged to improve the social welfare and public interests. However, the government alone cannot afford to meet the rapidly increasing social and economic needs, and therefore, the roles of the non-profit corporations become more and more important to support the government function, while people are more concerned about the tax systems related to establishment and activities of the non-profit corporations. With such basic conceptions in mind, the purpose of this study is to suggest the improvement for the tax system of non-profit corporation in comparison with foreign systems. To accomplish this objective, this study reviewed the existing relevant studies and literatures. By the results of this study, I suggested some improvements for two aspects of the corporation income tax and the value-added tax. The findings of this study will contribute to the settlement and development of the non-profit corporation in Korea.

To investigate the effects of short-term administration of DDB(Biphenyl Dimethyl Dicarboxylate) for decreasing elevated serum aminotransferase levels in chronic liver diseases, authors applied 3 capsules of DDB per day at each meal time for 35 patients and compared with 35 patients treated with other conservative management. The following results were obtained. 1. Serum alanine aminotransferase (ALT) levels significantly decreased from 247.1± 180.0 IU/L of pretreatment level to 96.6±126.0 IU/L, 61.1±62.7 IU/L and 38.0±26.8 IU/L after 1, 3 and 6 months of treatment(p<0.05) and effective rates were observed in 60.0%, 71.4% and 88.6% of patients after 1, 3 and 6 months of treatment. 2. Serum aspartate aminotransferase (AST) levels decreased also significantly from 167.8±96.9 IU/L of pretreatment levels to 124.4±155.0 IU/L, 77.9±49.6 IU/L, 60.6± 46.9 IU/L after 1, 3 and 6 months of treatment(p<0.05), but decreasing pattern of serum AST was less significant than that of serum ALT. 3. No significant difference were observed in the serum ALT and AST changes according to the cause and duration of hepatitis. 4. No significant adverse effects were observed in whole patients treated with DDB. It is suggested that small dose administration of DDB is effective for decreasing serum aminotrans ferase levels in chronic liver disease in which other conservative management was not effective.

A humidity sensor using porous silicon layer as humidity-sensing material is developed. Its structure was designed monolithically to be compatible to the integrated circuit technology, and the porous silicon layer was formed on p-type wafers with the low resistivity of 0.01 Ωcm to be stable mechanically. Proto-type sensors were fabricated using processes such as localized formation of porous silicon, oxidation of porous silicon layer, and etching of oxidized porous silicon layer. The dependence of capacitance on relative humidity was measured at room temperature, where the capacitance increased from 0.3 nF to 1nF for the relative humidity of 55 to 90% over.

The treatment of the tone defects resulting from trauma, neoplasm, surgery, or infection is one of the major concern in dentistry. The major goal is the functional, esthetical regeneration of supporting structures already destructed by disease. Transplantation technique have been used to provide a scaffold for bone regeneration, to augment bony defects resulting from trauma or surgery, to restore bone loss caused by dental disease, to prevent the collapse the alveolar ridge in recent extraction sites, to replace bone loss by periodontal disease, to augment the alveolar ridge in implant surgery. There are autogeneous, allogenic, xenogenic and alloplastic bone-grafts in transplantation. Among the alloplastic bone-graft materials, calcium phosphates have been received the most attention. In this study, the critical size defects were surgically produced in the calvarial bone of Sprague-Dawley rats using the 8 ㎜ trephine bur. Calcium phosphate glass powders with mean diameter 400 ㎛ transplanted onto the produced detects in the experimental group, while sutured without grafting anything in the control group. Histomorphometric as well as radiodensitometric analyses were performed after sacrifice at 2, 4 and 8 weeks following operation. The prepared calcium phosphate glass powder with average size 400 ㎛ in CaO-CaF_2-P_2O_5-MgO-Al_2O_3 promoted new bone formation in the calvarial defects in the Sprague-Dawley rats. New bone was formed in the upper side of the detects as well as the defect margin and dura mater. Experimental group always exhibited higher values in the length, area and density of the newly formed bone than that of the control group. There were significant differences between the experimental and the control groups, except the density after 4 weeks (p<0.05).

This study was conducted to analyze the storage and management status of major farm machinery, and to present the basic information for the construction of multipurpose storage housing suitable to the individual farmers by identifying current problems. The results of this study are summarized as follows; 1. The average farm area of the surveyed farmers was 4.25㏊, which represents relatively higher than the average of whole country. The mechanization rate for paddy farming was 98% so, the individual storage housing should be concentrated on the farm machinery utilized in paddy farming. 2. The annual operating span of the seasonal farm machinery (such as combine and rice transplanter) showed high difference between farmers and machines. For th rice transplanter, the highest portion of annual operation span was less than 10 days as 70%, and for the combine, that was over 20 days as 36% and the second was 16~20 days as 23%. The average difference in repairing cost for combine between the farmers with and without common storage housing was 100,000won. 3. The percent of storaging farm machinery in the open field for farmers without housing were 44% for power tiller, 16% for farm tractor, 21% rice transplanter, 10% for combine. Each farmer has individual temporary simple housing with various kinds and structure. 4. Most of the farmers, 63.7%, want to use the farm machinery storage housing for multipurpose utilization, 29% only for storaging purpose. Most farmers prefer near the farm house as suitable position of housing, and prefer the area of 132~198㎡ for storage housing. The current problems on common storage housing were insufficient area(44.8%), no problem(29%), improper position, excessive construction cost, inconvenient entrance, etc.

In this study, ozone was adopted for the reduction and stabilization of waste sludge from the municipal sewage treatment plant. The waste sludge used in the experiments was primary sludge, excess sludge and a mixture of the two. The sludge cells and flocs were disrupted by ozonation resulting in the reduction of TSS and VSS concentrations. In the case of the primary sludge with a concentration of 20 gTS/L, the TSS and VSS concentrations were reduced 28%, 33% and the TCOD concentration was reduced 20% respectively. The consumption of ozone was 0.18 gO₃/gSS. In the case of the excess sludge with a concentration of 7.5 gTS/L, the TSS and VSS concentrations were reduced 37%, 41%, and the TCOD concentration was reduced 19% respectively. The consumption of ozone was 0.33 gO₃/gSS. In the case of the mixed sludge of 9.3 gTS/L, the TSS and VSS concentrations were reduced by 45%, 53%, and the TCOD was reduced 26% respectively. The desirable consumption of ozone was 0.27 gO₃/gSS. As ozonation proceeded, the level of SCOD increased due to the release of intracellular materials. However TCOD was reduced due to mineralization resulting from the transformation of organic materials to inorganic materials.
