김성빈,김성회,박영범,문홍석,Kim, Seong-Bin,Kim, Sung-Hoi,Park, Young-Bum,Moon, Hong-Suk 대한치과보철학회 2013 대한치과보철학회지 Vol.51 No.3

무치악 환자의 임플란트 보철 치료는 지지, 유지, 안정성, 발음 등의 측면에서 더 우수한 결과를 보인다. 임플란트를 이용한 무치악 환자의 치료는 다양하며, 크게 가철성과 고정성으로 나눌 수 있다. 가철성 치료에는 임플란트 유지 및 지지 피개의치가 있으며, 고정성 보철치료에는 ceramo-metal 보철물과 임플란트 하이브리드 보철물(implant hybrid prosthesis)이있다. 치료계획의 수립은 잔존 치조제, 연조직, 악간 관계, 환자의 경제적 상황 등을 종합적으로 고려하여 수립해야 한다. 임플란트를 이용한 하이브리드 보철물은 고정성 치료를 통해 환자에게 적절한 교합력을 제공하고 심리적인 안정감을 주는 동시에 적절한 연조직의 회복을 통한 심미적인 결과를 얻을 수 있다. 본 증례는 73세 여환으로 상악 Kennedy Class I 부분 무치악과 하악 무치악 상태로 내원하였다. 상악에는 우측 견치부터 좌측 제1소구치까지 7개의 잔존치를 이용한 가철성 국소의치, 하악은 양측 측절치와 제1소구치 부위에 4개의 임플란트 고정체를 이용한 하이브리드 보철물로 최종 치료 진행하였으며 치료 후 기능적, 심미적으로 만족스러운 결과를 얻었기에 이를 보고하고자 한다. Implant prosthodontics is beneficial for edentulous patients in enhancing the support, retention, stability, phonation and so on. Various types of prosthesis supported by implant, including implant retained- or supported- overdenture for the removable type and ceramo-metal and fixed prostheses with processed acrylic teeth for the fixed type, are frequently used. Treatment planning for the prosthesis with implant must be made after considering individual characteristics such as form of residual ridge, soft tissue, interocclusal relationship, economic status. Fixed prosthesis with processed acrylic teeth (also known as 'implant hybrid prosthesis' or 'bone anchored bridge') has the advantages of both removable and fixed prosthesis such as proper soft tissue profile, esthetic outcome, increased masticatory efficiency and psychological stability. The 73-years-old female patient came to the department of prosthodontics, Dental hospital of Yonsei University. She was diagnosed with Kennedy class I partial edentulism in the maxilla and complete edentulism in the mandible. This article reports a satisfactory clinical and esthetic outcome of full mouth rehabilitation using removable partial denture in the maxilla and implant hybrid prosthesis in the mandible.

Technegas 스캐닝 후 중력환기에 의한 공간선량율 측정

김성빈,원도연 한국방사선학회 2019 한국방사선학회 논문지 Vol.13 No.4

Because examination with technegas produces images through simple diffusion accumulation, the examination room can become contaminated after scan. Therefore, radiation workers and patients awaiting examination will be affected by internal exposure from technegas inhalation. Before and after gravity ventilation, I am trying to find a way to reduce the exposure dose of waiting patients according to a comparative analysis of horizontal spatial dose rates over time. Spatial dose ratio were measured for 10 minutes from various distances and angles around ventilator’s location before and after gravity ventilation. Then, mean values, standard deviation and reduction ratio were calculated. The highest reduction rate of gravity ventilation was 95.31% and the highest reduction ratio was 1 to 3 minutes. Therefore, the gravity ventilation could reduce the exposure dose of radiologic technologists, waiting patients, patient guardians and nurses. In conclusion, the reduction of the exposure dose during the technegas ventilation study through gravity ventilation will play a role in optimiging the protection and it is in accordance with the recommended reduction of the medical exposure by ICRP 103. Technegas를 사용한 검사는 단순 확산 누적을 통해 폐 영상을 이미지화하기 때문에 검사를 마친 후에 검사실이 오염될 수 있다. 따라서 방사선 작업 종사자와 검사를 기다리는 환자는 technegas 흡입으로 인한 내부 피폭의 영향을 받게 된다. 이에 중력환기 전후의 시간경과에 따른 공간선량율 분포를 비교, 분석함에 따라 방사선사, 의료진, 대기 환자의 피폭선량 저감화 방법을 모색하고자 한다. 중력환기 전후 환자의 호흡기 위치에서 거리별, 각도별로 공간선량율을 10분 동안 측정하고 평균값, 표준 편차 및 감소율을 계산하였다. 실험 결과, 중력 환기 전후 감소율은 최고 95.31%였고 가장 높은 감소율은 1 ∼ 3분 사이에서 나타났다. 중력환기를 통해서 방사선 작업종사자, 대기환자, 환자 보호자 및 간호사의 피폭선량을 감소시킬 수 있다. 결론적으로 중력환기를 통한 피폭선량 감소 결과는 방호 최적화를 이루는 역할을 할 것이며 ICRP 103에서 권고한 의료 피폭 저감화에 부합된다.

LabViewⓇ기반 6축 수직 다관절 로봇의 파라미터 스케쥴링 프로그래밍에 관한 연구

김성빈,정원지,김효곤 한국생산제조학회 2015 한국생산제조학회지 Vol.24 No.3

As industrial robots come into wider use, their control techniques are being developed along with enhancements in their performance. Specially, the dynamic performance of a 6-axis articulated industrial robot is greatly changed according to the position and orientation of the robot. This means that the PI parameter tuning of the robot and orientation of the robot. This mconsidering the dynamic characteristics of robot mechanism. In this study, LabView® programming was applied to automatically conduct parameter scheduling for various robot motions. Using forward and inverse kinematics of RS2, we can divide the working envelope of RS2 into 24 subspaces. We then conduct the gain-tuning according to each subspace. Finally, we program the actual gain scheduling, in which the optimized gain-tuning for each subspace to be passed should be changed for various robot motions using LabView®.

One of the rising problems inthefield of environmental engineeering is the eutrophic phenomenon which appears in the closed water basin. This study is the elimination of orthophosphate by adsorption, which is indispensible nutritive element for eutrophication. Ziriconium(Ⅳ) oxide hydrate-activated carbon complex, which has excellent adsorptivity for orthophosphate and can easily be reused after desorption process, has been made and used as adsorbents. The main purpose of this study is to obtain intrapariticle diffusivity which is basic data for the design of adsorption operation the experimental results were as follows. 1. Optimum condition which gave maximum adsorption of orthophosphate was pH5 2. Equilibrium adsorption showed good consistency with Freundlich type. q=10.80C1/2.08 3. Pore diffusivity and surface diffusivity obtained the kinetic experiment of batch adsorption were respectively 5.38 and 2.06 (㎠/sec)

Soil CO2 Efflux and Leaf-Litter Decomposition of Quercus variabilis and Pinus densiflora Stands in the southern region of Korean peninsular

김성빈,이계한,정남철 한국산림과학회 2009 한국산림과학회지 Vol.98 No.2

It is necessary to determine the amount of carbon dioxide (CO2) absorbed by plants, released from forest floor into atmosphere, to gain a better understanding how forests participate in the global carbon cycle. Soil CO2 efflux, litter production, and decomposition were investigated in Q. variabilis and P. densiflora stands in the vicinity of Gwangju, Chonnam province. Soil CO2 efflux was measured using Infrared Gas Analyzer (IRGA) at midday of the 10th day at every month over 12-month period, to quantify seasonal and annual budgets of soil CO2 efflux. Soil temperature and soil moisture were measured at the same time. Seasonal soil CO2 efflux in Q. variabilis and P. densiflora were the highest in summer season. In August, maximum soil CO2 efflux in Q. variabilis and P. densiflora was 7.49, 4.61 CO2 μ㏖·m-2·s-1, respectively. Annual CO2 efflux in each stand was 1.77, 1.67 CO2 kg·m-2 respectively. Soil CO2 efflux increased exponentially with soil temperature and related strongly in Q. variabilis (r2=0.96), and in P. densiflora (r2=0.91). Litter production continued throughout the year, but showed a peak on November and December. Annual litter production in the Q. variabilis and P. densiflora stands were 613.7 g dw·m-2·yr-1 and 550.5 g dw·m-2·yr-1, respectively. After 1 year, % remaining mass of Q. variabilis and P. densiflora litter was 48.2, 57.1%, respectively. The soil CO2 efflux rates in this study showed clear seasonal variations. In addition, the temporal variation in the CO2 efflux rates was closely related to the soil temperature fluctuation rather than to variations in the soil moisture content. The range of fluctuation of soil CO2 efflux and litter decomposition rate showed similar seasonal changes. The range of fluctuation of soil CO2 efflux and litter decomposition rate was higher during summer and autumn than spring and winter.
