As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

홍용신,박은진,김선종,김명래,허성주,박지만 대한치과보철학회 2012 대한치과보철학회지 Vol.50 No.1

최근 디지털 인상채득 시스템이 개발되면서 이를 기존의 CAD/CAM 시스템과 접목한 인레이, 온레이, 크라운이나 간단한 계속가공의치 등의 고정성 보철물의 제작이 활발히 소개되고 있다. 그러나 임플란트 보철에서는 주로 기존의 아날로그식 인상채득 후 이를 스캔하여 제작하는 방법이 사용되어 왔으나, 구강 내 디지털 스캔한 데이터를 이용하여 나사형 보철물을 제작하는 술식은 아직 활발히 이루어지지 않았다. 이에 본 증례보고에서는 6명의 환자를 대상으로 구강 내 스캐너인 iTero를 사용하여 디지털 스캔을 시행한 후 그중 다섯명은 맞춤형 지대주와 시멘트 합착 후 나사형 임플란트 보철물(screw-retained implant prosthesis after cementation, or SCRP)을 제작하였고, 임상적으로 기능과 심미적인 측면으로 만족할 만한 결과를 얻었기에 이를 보고하고자 한다. Fixed dental prostheses such as inlay, onlay, crown, and bridge fabricated by CAD/CAM technique combined with digital impressions is getting popular due to the recent rapid progress of digital impression taking system. For the scope of implant prosthesis, however, digital intra-oral scan hasn’t been actively utilized for the fabrication of superstructures. In this case report, 6 cases of titanium-milled custom abutment based on the iTero intra-oral scan data were introduced, five of them were restored with screw-type prosthesis after cementation (SCRP) and the clinical results were satisfactory on restoring the function and esthetics.

구강 스캐너와 CAD/CAM 기술로 인해 컴퓨터로 제작하는 방식이 활발히 보급된 고정식 보철 증례와는 달리, 의치를 디지털 방식으로 제작하는 데에는 아직 한계가 많다. 촉각을 느낄 수 있는 입력 장비와 전자 서베잉의 개념, 그리고 쾌속 조형법의 적용으로 인해 국소의치를 디지털로 제작할 수 있는 솔루션이 최근 소개되고 있다. 본 증례보고에서는 이러한 국소의치의 디지털 솔루션을 이용하여 총 다섯 명의 환자에서 서베이드 금관 및 국소의치를 제작하였다. 인상 과정상의 문제로 모형과 실제 치아 사이의 형태적 차이가 있었던 경우를 제외하고는 국소의치의 적합도는 우수했으며, 장착 후 안정성과 착탈 시의 유지력 또한 임상에서 적용하는 데에 문제가 없었다. There are still many limitations on fabricating dentures using digital method while computerized production of fixed prostheses utilizing intraoral scanner and CAD/CAM technology has propagated rapidly. Recently the digital solution of fabricating removable partial denture by applying haptic input device, electronic surveying, and rapid prototyping was introduced. In this case presentation, five patients were treated with surveyed crown and removable partial dentures by this digital solution. Fit of dentures was excellent except for one case which showed morphological difference between the actual teeth and that of master cast by the erroneous impression process. There also was not any problem of stability and retention after adaptation in the clinical setting.

林業稅制에 關한 考察 : 韓國, 日本, 美國의 制度에 대하여

金知洪,辛在萬,尹鐘和 江原大學校 森林科學硏究所 1985 Journal of Forest Science Vol.5 No.-

Introduced with a review of general taxation principles in Korea, the article provides details of the main type of tax related to forest resource management. The forest taxation of Japan and the United states is also examined to compare with the Korean legislation. The basic analysis is made upon provisions and interpretation of each tax, its history, and its influence on forest management. For Korean forest taxation, some points to be considered are as follows. 1) Since 500,000 won of special income tax deduction from total forest revenue is not likely to be remaining with its absolute value, it should be variable by socio-economic situation. 2) Income tax exemption from newly reforested land for 40 years may shorten rotation and induce heavy harvest cutting for long-term commercial timber species. 3) With a few exceptions, general forest managers are not offered favors in death tax and property tax for their forest land. Taxes have frequently been called the primary impediment factor for timber production because the effectiveness of incentives of programs has not been provided. Considered to the specific characteristics of forestry and resource conservation, Korean forest taxation should be revised and complemented to encourage forest management or maintenance.

The purpose of the present study was to evaluate the bioequivalence of two nizatidine capsules, Axid (Lilly Korea Pharm. Co., Ltd.) and Nex (Bi-nex Pharm. Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). The nizatidine release from the two nizatidine capsules in vitro was tested using KP Apparatus method with various dissolution media (pH 1.2, 4.0, 6.8 buffer solutions and water). The dissolution profiles of two nizatidine capsules were very similar at all dissolution media. Twenty four normal male volunters were divided into two groups with a randomized 22 cross-over study. After two capsules (300 ㎎ nizatidine) were orally administrated, blood as taken and the concentrations of nizatidine in serum were determined using HPLC with UV detector. The pharmacokinetic parameters such as AUC_(t), C_(max) T_(max) were determined. The result showed that the differences in AUC_(t), C_(max) and T_(max) between two nizatidine capsules absed on the Axid were-6.16%, -8.26% and -1.82%, respectively. There were no sequence effects between two capsules in these parameter. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log(0.8) to log(1.25)(e.g., log(0.91) ∼log(0.97) and log(0.85)∼log(0.99) for AUC_(t) and C_(max), respectively), indicating that Nex capsule is bioequivalent to Axid capsule.

To develop an intravenous delivery system of all-trans retinoic acid (ATRA) for the cancer therapy, poly(L-lactic acid) nanoparticles were prepared and characterized. Emulsification-solvent evaporation method was chosen to prepare submicron sized nanoparticles. Spherical nanoparticles less than 200 nm in diameter with narrow size distribution were pre-pared, and the entrapment efficiency of drug was more than 95%. The endothermic peak at 183°C and X-ray crystallographic peak of ATRA appeared in the nanoparticle system, suggesting the inhibition of crystallization of ATRA by polymer adsorption during the precipitation process. ATRA was released at 37℃ for 60 days and the release rate was dependent on the concentration of drug incorporated in the nanoparticles. While ATRA was unstable in the light, it was very stable at 4℃. These results suggest the usefulness of PLA nanoparticles as a sustained and prolonged release carrier for ATRA.

The purpose of this research is to estimate a safe environmental level of human exposure to thresholding acting toxicants in drinking water and recommend the acceptable levels and management plans for maintaining good quality of drinking water and protecting health hazard. This research has been funded as a national project for three years from 1992 to 1995. This study(the second year, 1993-1994) was conducted to monitor 39 species of non-carcinogenic chemicals such as volatile organic compounds(VOCs), polynuclear aromatic hydrocarbons(PAHs), pesticides and heavy metals of drinking water at some area in six cities of Korea, and evaluate health risk due to these chemicals through four main steps (hazard identification, exposure assessment, dose-response assessment and risk characterization) of risk assessment in drinking water. In hazard identification, 39 species of non-carcinogenic chemicals were identified by the US EPA classification system. In the step of exposure assessment, sampling of tap water from the public water supply system had been conducted from 1993 to 1994, and 39 chemicals were analyzed. Indose-response assessment for non-carcinogens, reference doses(RfD) and lifetime health advisories (HAs) of lifetime acceptable levels were calculated. In risk characterization of detected chemicals, the hazard quotients of noncarcinogens were less than one except those of manganese and iron in D city.

In dorsal laminectomy for the surgical treatment of thoracolumbar disc disease in dog, the bur could slip into the vertebral canal. For the decrease of this probability of danger, osteotome was used with instruments such as bur and rongeur in dorsal laminectomy. At thoracic vertebrae (T10-T11) and lumbar vertebrae (L5-L6) area, dorsal laminectomys were performed in a dog. In observation for 3 months after surgery, the dog revealed healthy physical condition. For the confirmation of healing condition at 3 months after dorsal laminectomy, two surgical sites were exposed by incision. Excellent healing response was observed with no adhesion and fibrosis in the vertebral canal.

This study was performed to identify risk factors for depression among the elderly in a rural area. A survey was done for the elderly living in Gosam-myenn, Ansung-kun during the period of July 28, 1997 and July 30, 1997. Demographic and sodoeconornic characteristics, and functional and health Status were assessed using a structured questionnaire, and the level of depression was measured by GDS score. The data obtained were analyzed by frequencies, percentage, t-test, ANOVA, and multiple regression, and the results were as follows: 1. The total sample consisted of 133 elderly. Of them, 47 elderly (35.4%) showed significant depressive Symptoms. 2. The GDS score was the highest for the group over 85 years of age (p < 0.05). Those living alone or widowed showed lower GDS score than those living with someone or married (p < 0.05). 3. The GDS score was the highest in the absolutely dependent group, followed by the partially dependent group, and the independent group (p < 0.01). The elderly who perceived their health Status as excellent showed the lowest GDS score. In contrast, those who had more than five chronic diseases showed the highest GDS score. 4. The elderly receiving financial and emotional support from their family or friends showed lower GDS score compared to those without any support. 5. The economically dependent group showed higher GDS score than that of independent group. 6. The elderly who involved in leisure activities showed lower GDS score than those without any involvement. 7. In terms of risk factors for depression, we found that perceived health Status, subjective economic Status, leisure activities, living arrangement and financial support were inversely associated with GDS score, whereas labor support was positively associated with GDS score. Based upon the above findings, this study suggests that these risk factors for depression in the elderly should be taken into consideration for a comprehensive mental health program for the elderly living in the rural area.
