PET-CT 검사 환자의 피폭선량 감소를 위한 기초자료 제공의 일환으로 PET-CT 검사 환자의 방사선량률의 변화를 분석하고자 하였다. PET-CT 검사 환자의 방사선량률을 측정한 결과 이론과 같이 방사성의약품이 투여된 환자로부터 거리가 멀수록, 시간이 지날수록 방사선량률은 감소되는 것을 볼 수 있었다. 특히 신체부위에 따라서는 방사성의약품 정맥 주사 즉시인 약 4.17분에서는 흉부, PET-CT 검사 전 배뇨 후인 약 77.47분 이후부터는 두부가 가장 높게 나타났다. 일반화되어 있는 정보와 같이 PET-CT 검사 환자로부터 받는 방사선 피폭량을 감소시키기 위해서는 보호자나 방사선작업종사자가 환자로부터 거리를 멀리하거나 방사능이 감소된 이후의 시간부터 접촉하는 것이 바람직하다. 불가피한 접촉이 필요하다면 가능한 거리는 200 cm이상을 확보하는 것이 바람직하다. 또한 초기에는 흉부, 방사성의약품 투여 후 약 77분 이후부터는 두부에 방사선량률이 높기 때문에 환자 신체적 특징을 고려한 접촉도 함께 이루어진다면 최적화 달성에 도움이 될 것이라고 보여 진다. 본 연구에서 도출된 PET-CT 검사 환자의 거리, 시간, 신체부위에 따른 방사선량률 변화를 알 수 있다는 점에서 연구에 의의가 있다고 본다. 향후 연구에서는 본 연구에서 도출된 결과를 바탕으로 환자 개인특성에 따른 방사선량률의 변화 차이를 분석하여 환자, 보호자, 종사자의 피폭선량 감소에 활용할 수 있도록 지속적인 연구가 수행되는 것이 필요하다고 본다.

본 연구는 환자의료정보 보호에 대한 의료기관 종사자들의 인식도 및 실천도의 관계를 규명하여 의료 기관의 의료정보 보호의 정책 수립에 기초자료를 제시하고자 실시하였다. 연구 결과, 연구기간 및 대상은 2019년 6월 17일부터 8월 16일까지 전라남·북도에 소재하고 있는 의료 기관 종사자 200명을 대상으로 하였다. 설문지조사는 연구자가 직접 조사 대상에게 연구 목적을 설명하고, 설문지를 배포한 후 회수하였다. 환자의료정보 직접 접촉영역 측정도구는 총 5문항, 환자의료정보 관리영역은 총 14문항, 의사소통영역은 총 8문항이었다. 연구결과, 의료기관 종사자의 영역별 환자 의료정보 보호에 대한 인식도와 실천도는 의사소통 영역이 가장 높았고, 다음으로 환자 의료정보 관리영역 의료 정보 직접접촉 영역 순이었다. 환자의료정보 보호에 대한 인식도과 실천에 관련이 있었던 변수는 의료기관 유형, 직무만족도, 종교, 근무부서와 유의한 관련이 있었다. 환자의료정보관리 영역에 영향을 미치는 요인을 알아보기 위해 환자의료정보 직접 접촉영역과 의사소통영역을 독립변인으로 환자의료정보관리 영역을 종속변인으로 하여 다중 회귀분석을 실시한 결과 환자의료정보 직접 접촉 영역과 의사소통영역이 높을수록 환자의료정보관리 영역이 높아짐을 알 수 있었다. 본 연구의 결과를 통해 의료기관 종사자들의 의료 정보 보안 및 보호 행위에 대한 인식수준을 높일 수 있도록 직종별, 직무별 교육프로그램을 개발하여 내부감사 형태의 주기적인 모니터링과 함께 지속적인 교육을 실행하여 환자 의료정보 침해 환경으로부터 환자를 보호하고 피해를 최소화 할 수 있도록 노력해야 할 것이다.

This study was performed to investigate the factor that might affect mandibualr body rotation. For the study, 115 patients with temporomandibular disorders and 35 dental students without angy signs and symptoms of temporomandibular disorders were randomly selected as the patient group and the contreol group, respectively. Preferred chewing side, Angle' classification, lateral guidance pattern, and affected side were clinically recorded, and the amount of Mandibular body rotational torque movement was measured in wide opening and closure, in right and left excursion with vertical and lateral distance in frontal plane, right and left rotational angel in horizontal and in frontal plane. Masticatory muscle activity of anteriorocclusal contact pattern on maximal hard biting were also observed synchronously with BioEMG and T-Scan , respectively. The observed items were muscle activity of anterior temporalis and superficial masseter, and tooth contact status related to contact number, force, duration, and occlusal unbalance between right and left arch. The data collected were analyzed by SAS statistical program. The results of this study were as follows : 1. Mean value of vertical distance in frontal plane in wide opening and closure was more in control subjects than in patients, but there was no difference for rotational angle. In right excursion, rotational angles were greater in patient group than in control group. 2. Comparison among the subjects by preferred chewing side did not reveal any significant difference, but comparison among patients by affected side showed more rotational amount in bilaterally affected patients than in unilaterally affected patients. 3. Comparison among the subjects by Angle's classification or lateral guidance pattern revealed no difference. There was also no difference between preferred chewing side and contralateral side, and between affected side and contralateral side. 4. Positive correlation in madibular rotational torque movements were observed among vertical distance, total horizontal rotation angle, electromyographic activity of anterior temporalis, tooth contact number, and tooth contact force but total frontal rotation angle almost did not show any correlation with other variables except vertical distance.

목적: 대학병원에 근무하던 중 활동성 폐결핵으로 진단된 전공의에게 노출된 의료종사자들에 대하여 실시한 접촉자 조사의 결과를 보고한다. 방법: 활동성 폐결핵 환자와 밀접한 접촉을 한 사람(접촉자) 101명 중 89명이 접촉자 조사에 응하여 조사를 받았다. 1차 접촉자 조사는 지표환자의 증상 개시 후 30일경에, 2차 조사는 1차 조사 10주 후에 기침, 발열, 인후통, 체중 감소와 같은 임상증상 확인 및 단순흉부촬영과 함께 결핵반응검사(Tuberculin skin test, TST)/QuantiFERON-TB Gold (QFT-G) 2단계 검사법을 시행하였다. 결과: 1차 TST 양성자는 34명(38.2%)이었고, TST 양성자 중 35세 이하 접촉자에서 시행한 QFT-G 양성률은 37.5% (6/16)이었다. 1차 TST 음성 대상자 41명에게서 시행한 2차 TST에서 17명(41.5%)이 양전을 보였고 그들 중 시행한 QFT-G 검사에서 3명(17.6%)이 양성이었다. 활동성 결핵으로 진단된 접촉자는 없었으며 지표환자에 노출되어 발생한 결핵 전파율은 2단계 검사법으로는 7.3% (3/41)였고, TST 진단법으로는 41.5% (17/41)였다. 결론: 국내에서 처음 보고되는 병원 내 결핵 접촉자 조사 연구로서 LTBI 발생률이 그 진단 기법에 따라 달랐으며 따라서 앞으로 발생할 수 있는 의료종사자들에 대한 병원 내 결핵 접촉자 조사를 위해 조직적이고 실용적인 가이드라인이 필요할 것이다.

The purpose of this preliminary report was to describe the operating procedure of T-scan system and to identify the location, timing and force of occlusal contact in patient with normal occlusion using computerized T-scan system. From the preliminary observation , the author obtained the following results. 1. T-scan system displayed 2 dimensional and 3 dimensional description of occlusion: contact locations, timing (sequence) and forces of occlusal contacts. 2. The T-scan sensor was the most important part of the T-scan system. 3. The data of T-scan system cannot be stored in computer diskett. 4. The T-scan system is thought to be the most effective system to detect occlusal contacts and can be applied to the followings : occlusal diagnosis, occlusal equilibration, crown and bridge restorative procedures, denture adjustment, implant procedures, splint adjustment, laboratory procedures, periodontal treatment, orthodontics, TMJ treatment and patient education etc.

The bacteria infection on film cassette contact surface was examined at the diagnostic radiology department of the S. hospital. The objective of this study was to assess the contamination level on film cassette contact surface as a predictor of patient prevention from nosocomial infection and for improvement of the hospital environment. The laboratory result was identified non-pathologic bacterial in the five different cassette size of the contact surface. Film cassettes were exposed to ultraviolet light for 1, 2 and 3 minutes. Ultraviolet light disinfection is proven suitable for bacteria. The study concludes that presence of a bacterial infection will prevent a using antiseptic technique on film cassette contact surface. In addition education of nosocomial infection for radiographers will be required. In conclusion, ultraviolet is considered effective to irradate bacteria. Additionally, two minutes are required to sterilize film cassettes.

Many types of occlusal splints are used for treatment of craniomandibular disorders. Most widely used splint among them is flat-type centric relation splint. Insertion of splint into the mouth may cause increasing of vertical dimension, masticatory muscle realignment and rearrangement of maxillo-mandibular relationship, so as a result of splint treatment, occlusal relation may vary whether you like it or not. From this point of view, occlusal state of patient shold be frequently monitored to prevent undesired or harmful effect during occlusal splint therapy. The purpose of this study was to investigate the effect of occlusal splint, especially centric relation splint, on the occlusal contact state after 3 months treatment. 32 patients with craniomandibular disorders who had unilateral symptoms participated in this study. To observe and record occlusal contact state, the author used T-Scan system (Tekscan Co. U.S.A.) at both pretreatment and posttreatment. The recorded date were analyzed with regard to contact number, contact force and contact time, change of anterior tooth contact and coincidence of first contact point with affected side were observed, too. Aan last, the subjects were divided into 2 groups and compared, according to average value of VAS index, with respect to joint pain, sound and limitation of movement, respectively. The collected date were statistically processed with SPSS and the result as follows : 1. Total occlusal contact number and force were not changed by occlusal splint therapy but total occlusal contact time decreased slightly. 2. There was a tendency of increasing number of subjects with anterior tooth contact after treatment and change of first contact point side were observed in as many as 40.6% of subjects. 3. There were no difference between higher and lower group of VAS index, and between pretreatment and posttreatment in each group, either.
