(Se, S) 계 비정질 박막의 광특성 및 Grating형성에 관한 연구

김종빈,정홍배,김하석 조선대학교 동력자원연구소 1989 動力資源硏究所誌 Vol.11 No.2

This paper was investigated on the optical properties, including the transmittance, the absorption coefficient, the optical energy gap and the photodarkening effect in amorphous As-Se-S-Ge system thin films. Utilizing the characteristics, the diffraction grating of the amorphous film was obtained. The interference pattern was recorded with an Ar^+ laser(488nm), while an He-Ne laser (632.8nm) was used to read the recorded grating simultaneously. Parameters such as the film thickness, the composition rate, the exposure time and the exposure power influencing the diffraction efficiency were also studied. The maximum diffraction efficiency, 4.6%, was obtained in a 0.76um thick of As_40Se_15S_35Ge_10 thin film.

김종빈,김종수,박지은 大韓小兒齒科學會 2007 大韓小兒齒科學會誌 Vol.34 No.4

2003년 4월부터 2006년 4월까지 안양 지역에 위치한 개인 소아치과 병원에 내원한 환아 7038명을 대상으로 임상적,방사선학적 검사를 통해 성별,상악 정중과잉치의 수,치관의 형태와 위치,치관 방향을 조사하여 다음과 같은 결론을 얻었다. 1. 과잉치를 가진 환아는 239명으로 3.40%(총 241명. 3.42%)에 해당하였고 총 289개의 과잉치가 있었다. 2. 과잉치는 1개 있는 경우가 191명으로 가장 많았고, 2개 있는 경우도 48명 있었으며 3개 이상 있는 경우는 없었다. 3. 상악 정중과잉치는 3.2:1로 여아보다 남아에서 호발하였다. 4. 과잉치는 왼쪽에 있는 경우가 55.4%로 약간 더 많았고,모양은 원추형,방향은 역위형이 가장 많았다. 5. 하악 정중과잉치는 2명에서 관찰되었다. The purpose of this study was to evaluate the prevalence of mesiodens at pediatric dental clinic in Anyang, Kyeong Gi-Do. From retrospective reviews of all patients who visited Kizwell pediatric dental clinic from 2003.4-2006.4, 241 patients (289 mesiodens) who were shown to have mesiodentes were examed by a periapical radiograph and a panoramic radiograph. The incidence of mesiodens was 3.42% and the ratio of male/female (184/57) was 3.2:1. The number of supernumerary teeth was one in 193 cases (80%), two in 48 cases (20%). The mesiodens was placed at left side more frequently and the most common shape was conical type (208, 78%). Of 289 mesiodens, the direction of the crown of the mesiodens was inverted in 156 (54%), in a normal direction in 104 (36%), in a horizontal direction with regard to the tooth axis in 29 (10%). Early diagnosis of the mesiodens allow the most appropriate treatment, often reducing the extent of surgery, orthodontic treatment and possible complications.

One-Bottle 상아질 결합제의 유치 상아질에 대한 전단 결합 강도에 관한 연구

김종빈,김종수 대한소아치과학회 2000 大韓小兒齒科學會誌 Vol.27 No.3

치아 교환시기에 발거된 치관이 건전한 유구치 상아질 표면을 One-Bottle 상아질 결합체인 Primer & Bond NT(De Trey/Dentsply, Konstanz, Germany)와 Single Bond(3M Co. U.S.A.) 그리고 대조군으로 Scotchbond Multipurpose System(3M Co. U.S.A.)를 이용하여 각 제조자의 지침에 따라 처리하여 레진을 충전하고 광중합하였다. 1.전단 결합 강도의 측정결과 Primer & Bond NT군인 1군, Single Bond군인 2군, 그리고 대조군으로 사용된 Scotchbond Multipurpose System군인 3군의 순서로 1군에서 다소 높은 전단 결합 강도를 보였으나, 모든 군들간에는 통계적 유의차가 없었다(p〉.05). 2.주사 전자 현미경 소견에서 1군 2군에서 서로 유사한 양상의 잘 형성된 혼화층이 관찰되었으며, 레진 테그와 측방 가지 또한 다수 관찰되었다. 반면 3군에서는 혼화층이나 측방 가지의 형성이 1,2군에 비해 다소 미약한 양상을 보였다. 주요단어 : One-Bottle 상아질 결합체, 유구치 상아질, 전단 결합 강도, 주사 전자 현미경 To test the shear bond strength of a new "one-bottle adhesive" system to primary dentin two commercially available one-bottle adhesives(Prime & Bond NT, Single bond) and conventional three step system(Scotchbond Multi-Purpose Plus) were included for comparison. And We observe the interfacial morphology by scanning electron microscope. 90 primary molar teeth were embedded in acrylic and buccal and lingual surface were polished to 320 grit to create standardized dentin surface for testing. After bonding of composite resin to sample surfaces according to the manufacturer's direction and 1000 times thermocycling in dwell time 30 second, Shear bond strengths of adhesives to dentin were determined using universal testing machine and analyzed by ANOVA test. Another groups of specimens were treated by hydrochloric acid to secure the resin only and those tags were evaluated under SEM fur their length and forms and the morphology of the bonding sites were also observed The result are as follows 1 Group I(Prime & Bond NT) showed higher shear bond strength than groupⅡ(Single Bond) and Ⅲ(Scotchbond Multi Purpose Plus) but no statistically significant difference was founded between groups(p〉0.05). 2. Relating long resin tags of 70-120㎛ were observed in samples of all groups under SEM. We could observed hybrid layer, resin tag and many lateral branches in every group. But, we observed in groupⅢ rare lateral branched than other two group and discontinuous hybrid layer.

치과전문소생술(Dental Advanced Life Support, DALS)은 무엇인가요?

김종빈,Kim, Jongbin 대한치과의사협회 2020 대한치과의사협회지 Vol.58 No.10

The aim of this article is to provide major announcements within the last decade or so about possible medical emergencies in dentistry. This would be helpful to improve the knowledge on first aid suitable for dental environment. Syncope was the most common medical emergencies in dentistry. Medical emergency situations can be divided into urgency and true emergency. Urgency situations can be solved well if proper treatment is taken. However, even in an urgency, if the correct treatment is not performed, it may soon turn into an emergency. With the joint efforts of the Korean Dental Anesthesiology Society and the Korean Cardiopulmonary Resuscitation Association, dental advanced life support (DALS) has been prepared since 2015. Through 17 training experiences until January 2020, scenarios and textbooks were developed. Dentists and dental care teams need to be prepared to strengthen their competence as professionals and to increase their team-level response capabilities..

달리기 속도와 경사가 하지관절의 생체역학에 미치는 영향

김종빈 중소기업융합학회 2020 융합정보논문지 Vol.10 No.4

본 연구는 달리기 시 속도와 경사변화가 하지관절의 생체역학적 요인에 미치는 영향을 보고자 한다. 이를 위해 20대 성인남성 15명이 트레드밀에서 2.7, 3.3 m/s와 -9°, -6°, 0°, 6°, 9°로 달리기를 실시하였고, 속도와 경사 변화에 따른 주행특성(보장, 보빈도), 생체역학적 변인(발목, 무릎, 엉덩관절의 가동범위, 모멘트, 관절파워), 지면반력(수직지면반력, 부하율, 제동력, 추진력)을 측정하였다. 연구결과, 주행특성은 오르막 달리기(UR)가 내리막 달리기(DR)에 비해 크게 나타났다(p<.05). 하지관절의 가동범위와 수직지면반력은 UR에서 크게 나타났고(p<.05), 하지관절의 모멘트와 제동력, 추진력, 부하율은 DR에서 크게 나타났다(p<.05). 관절파워는 발목관절은 DR에서 크 고, 엉덩관절에서는 UR이 크게 나타났다(p<.05). 이러한 결과로부터 3.3m/s의 속도로 DR을 달리는 경우에서 발 목관절 부상의 영향이 클 것으로 예상된다. This study analyzes the effects of changes in running velocity and slope on the biomechanical factors of the lower limb joints. For this purpose, 15 adult males in their 20s ran according to changes in running speed (2.7, 3.3 m/s) and slope ( -9°, -6°, 0°, 6°, 9°) on the treadmill, and their running characteristics (stride length, stride frequency). The range of motion of the lower limb joint and the vertical ground reaction force were greater in UR (p <.05), and the moment of the lower limb joint, braking force, thrust and load factor was large in DR (p <.05). In joint power, the ankle joint was greater in DR, and hip joint was greater in the UR (p <.05). These results show that the injuries of the ankle joint will be greater than other cases when running DR at a speed of 3.3 m/s.

전력제어 통신 시스템의 에러 감소를 위한 ICCP 적용 방안

김종빈,정래성 대한전자공학회 2003 電子工學會論文誌-TC (Telecommunications) Vol.40 No.9

Because of capacity of the electric power equipment grew larger and the electric power system was complicated, it was required a protocol to process data without the errors in order to supply the high quality and stable electric power. However, HDLC and TCP/IP communication protocol using between Seoul EMS and Kwangju RCC (or between RCC and SCC) is decreasing reliability by the delay of speed and the occurrence of errors. In this paper, we applied ICCP(Inter-Control Center Communication Protocol) communication protocol in order to improve them and implemented an electric power communication system for remote control of the electric power equipment. Also, we modified program for error correction and implemented the system using the most suitable BLT. The errors were more decreased in case of ICCP protocol than HDLC protocol and TCP/IP protocol applied to the electric power communication system. 전력설비의 용량이 커지고 전력계통이 복잡해짐으로서 고품질과 안정적인 전력공급을 하기 위해 각 계층간에 연계되는 데이터를 에러 없이 처리하는 프로토콜을 요구하게 되었다. 그러나 서울(EMS)과 광주(RCC) 또는 RCC와 SCC에 사용하고 있는 HDLC나 TCP/IP 통신 프로토콜은 속도의 지연, 에러 발생 등으로 신뢰성을 감소시키고 있다. 이론 개선하기 위해, 본 논문에서는 ICCP 통신 프로토콜을 적용하여 전력 설비의 원거리 제어를 위한 전력 통신시스템을 구현하였다. 오류보정을 위해서 프로그램을 수정하였으며, BLT 최적 조건을 적용하여 구현하였다. 전력통신 시스템에 ICCP 프로토콜을 적용하였을 경우 HDLC와 TCP/IP 프로토콜을 적용한 경우보다 에러가 감소하였다.
