Background: Adenosine interacts with A1 receptors present on the extracellular surface of cardiac cells, activating K+channels in a fashion. It produces coronary vasodilatation and AV nodal block. The half-time is one to six second and has ultra-short action. In ischemic heart disease, fractional flow reserve(FFR) can be achieved safely with intravenous adenosine infusions at a rate of 150㎍/kg/min which cause maximal coronary hyperemia. Purpose: We investigated the patients who have had ischemic heart disease(n=8). After adenosine intravenous administration(150㎍/kg/min), the effect cause maximal hyperemia of coronary artery. During peak maximal hyperemia, we reported clinical findings, coronary hemodynamics and electrocardiogram findings. Methods: After diagnostic coronary angiography and left ventriculography, catheter was advanced into the ostium of coronary artery. We investigated coronary hemodynamics such as systolic coronary artery pressure, diastolic coronary artery pressure, mean coronary artery pressure and heart rate. To assess the use of adenosine for determination of fractional flow reserve, hemodynamics and electrocardiogram were measured at basal state and during peak maximal hyperemia. Results: Symptoms developed 1.5-2 minute after adenosine intravenous administration and each symptom disappeared 2-2.5 minute after adenosine administration. Two patients represented asymptomatic appearance and six patients complained of flushing, chest pain, palpitation and headache. In eight patients with ischemic heart disease, 1.5 minute after venous administration of 150㎍/kg/min of adenosine, coronary artery pressure decreased and heart rate increased significantly. Conduction abnormalities after administration of 150㎍/kg/min of adenosine were transient 2nd degree AV block 2 cases(25%). Conclusions: Adenosine is a potent ultra short-acting vasodilator. Although coronary artery pressure decreased and heart rate increased and mild cardiovascular symptoms occurred after continuous infusion of 150㎍/kg/min of adenosine, it is useful as an agent for determination of fractional flow reserve.

This study was to investigate if cervical vertebrae maturation stages are as useful as hand-wrist maturation stages in evaluating the mandibular growth. The subject consisted of 292 girls aged from 8 to 16 years with normal occlusion. They were classified according to diagnosis by using studycast. lateral cephalogram, and handwrist X-ray film. The results were as follow: 1. Cervical vertebrae and hand-wrist maturation stages increased with age. 2. All mandibular measurements (Ar-Go, Go-Me, N-Go, S-Gn, N-Me) increased linearly with cervical vertebrae maturation stages. 3. Ar-Go, Go-Me, N-Go, S-Gn increased linearly with hand-wrist maturation stages. 4. Ar-Go, Go-Me, N-Go, S-Gn increased relatively rapidly between cervical vertebrae maturation stages 3 and 4. Go-Me and S-Gn increased relatively rapidly between hand-wrist maturation stages 6 and 7. 5. Ar-Go, Go-Me, N-Go, S-Gn, N-Me had high correlations with cervical vertebrae maturation stages as well as hand-wrist maturation stages. These results suggest that cervical vertebrae maturation stages are reliable on evaluating the mandibular growth. 하악골 성장을 평가하는 데 경추골 성숙도가 수완부골 성숙도만큼 유용한가 규명하고자 본 연구를 시행하였다. 정상교합을 가진 만 8세∼만 16세 여성 292명을 연구대상으로 하여 진단석고모형,측모두부규격방사선사진,그리고 수완부방사선사진을 이용하여 경추 및 수완부의 골성숙도를 비교하여 다음과 같은 결과를 얻었다. 1. 연령 증가에 따라 경추 및 수완부의 골성숙도가 일정하게 증가하였다. 2. 경추골 성숙도가 증가할수록 Ar-Go,Go-Me,N-Go,S-Gn,N-Me이 일정하게 증가하였다. 3. 수완부골 성숙도가 증가할수록 Ar-Go,Go-Me,N-Go,S-Gn이 일정하게 증가 하였다. 4. 경추골 성숙도 3단계와 4단계 사이에서 Ar-Go,Go-Me,N-Go,S-Gn이 크게 증가하였고,수완부골 성숙도 6단계와 7단계 사이에서 Go-Me,S-Gn이 크게 증가 하였다. 5. Ar-Go,Go-Me,N→Go,S一Gn,N-Me은 경추 및 수완부 골성숙도와 각각 유의 한 상관성을 보였다. 이상의 결과는 하악골 성장을 평가하는 데에 경추골 성숙도가 수완부골 성숙도처럼 유용하게 사용될 수 있음을 시사한다.

We studied the homogeneous plating on the dented part of door frame by decreasing or increasing the current density, installing air blower, adjusting the length between anode and cathode, using auxiliary anode, developing the new plating bath and etc. When we performed the zinc cynade plating, there was no way to achieve the homogeneous plating layer without using auxiliary anode. However, it wasn't a suitable and efficient method for appling to the real process. After we developed the plating bath that had the uniform current density, we were able to get the homogeneous plating layer of zinc on the dented door frame.

목 적 : 하청노동을 이용한 노동 유연화 전략은 근로자들의 고용을 불안정시키고, 근로자들의 삶에 부정적 영향을 미치고 있다. 따라서 이 연구는 하청업체 근로자들의 고용현황을 조사하고, 기존의 업체중심의 건강평가의 문제점을 지적하고자 하였다. 또한 하청업체 근로자들의 건강평가의 현재적 의미와 사회적 배제의 특성을 알아보고자 하였다. 방 법 : 모기업과 하청업체 근로자들의 건강수준을 비교하기 위하여, 정기건강진단(일반, 특수)과 채용건강진단 자료를 이용하고자 하였다. 건강진단에서 누락된 비정규직을 포괄하기 위하여 SF-36을 이용하여 건강설문조사를 시행하였다.결 과 : 조선업 하청업체 근로자들의 고용기간은 짧고, 빈번한 노동이동 현상을 보였다. 3년간 건강진단 수검 현황을 통해 살펴볼 때, 1998년 수검자중 2000년까지 연속해서 검진 받은 수검자는 40.3%였다. 건강진단 결과 유소견자 규모를 통해 모기업과 하청업체간의 건강수준을 비교해 보았다. 모기업은 일반질병 요관찰자와 질병자를 포함한 유소견자가 1,011명으로 약 10 %의 유소견율을 보이고 있고, 질병자의 경우 596명으로 유병률이 5 %를 상회하고 있다. 반면 하청업체의 경우 1,967명의 수검자중 유소견자가 115명으로 6 %의 유소견율을 보이고있고, 질병자는 82명으로 4 %의 유병률을 보이고있다 채용건강진단을 받은 수검자는 6,260명 이었으며, 이 중 유소견자 수는 2,373명으로 전체 수검자의 37.9 %를 차지하였다. 건강설문지의 경우는 전체 건강수준의 총합은 하청보다 원청 근로자가 높았고 통계적으로 유의하였다. 결 론' 정기건강검진 결과는 하청근로자들이 고용형태에 따라 검진을 받지 못한 경우가 많아, 건강 근로자 효과로 표현될 가능성이 있다. 따라서 채용건강진단 결과는 다른 측면에서 하청업체 근로자들의 건강수준의 현실적 반영이라고 할 수 있다. 향후 하청업체 근로자들의 건강문제를 감시하고 개선하려면 기존의 업체 중심의 접근으로는 하청 근로자의 건강문제를 제대로 다룰 수 없고, 업종과 지역을 동시에 고려하여 접근할 필요가 있다. 또한 단기 고용 근로자 및 비정규직 근로자를 사회보장의 확충과 모기업의 연대책임 강화 및 기업복지 차원에서 포괄하는 방안이 모색되어야 하겠다. Objectives : The strategy for the labor flexibility through subcontracted labor have brought a negative effect on the lives of the workers, such as the increase of the unstable employment. This study was conducted to analyze the relationship between the employment of subcontracted firms and the health status of them, and to find out some problems which have been caused in the process of health evaluation and the characteristics of social exclusion. Methods : We reviewed the periodical health examination and preemployment health examination in order to compare health status of the subcontracted workers with those of the parent firm workers. The SF-36 questionnaire was administered to assess the self-perceived health status. Results : The result shows that compared to the working duration of the parent firm workers, those of the subcontracted workers were shorter, and the job transfer rate was higher. In the periodical health examination, the prevalence of occupational and general disease was higher in the parent firm(10%) than in the subcontracted firms(6%). Preemployment health examination plays an important role in worker's health manage- ment. Among 6,260 workers who received preemployment health examination, the prevalence of disease was 37.9%. Mean scores of health status measured by SF-36 were lower in the subcontracted firm than in the parent firm. Conclusions : Due to social exclusion of the subcontracted workers from the periodical health examination, there is a possibility that the periodical health examination have the healthy worker effect. These results suggests that the preemployment health examination could be a more appropriate indicator which is able to assess the health status of the subcontracted workers than the periodical health examination.
