  • In this paper, a new active phase shifter is proposed using a vector sum method, and a unique digital phase control method of the circuit is suggested. The proposed scheme was designed and implemented using a Wilkinson power combiner/divider, a branch line 3 dB quadrature hybrid coupler and variable gain amplifiers (VGAs) using gate FETs(DGFETs). Furthermore, it was also shown that the proposed scheme is more efficient and works properly with the digital phase control method.

  • This study was conducted to assess the equity in the regional insurance scheme through analysis of the computerized data from one regional insurance society and National Federation of Medical Insurance. We analysed the insurance contribution and benefit by the classes based on total and income-related contribution per household. The major findings of this study are as follows : 1. The average proportion of income-related contribution among the total was 39.2% and the upper classes show higher proportion of the income-related contribution. 2. The upper classes show higher health care utilization rate than the lower classes. It suggests that the lower classes have relatively large unmet medical needs. 3. The analysis through the Lorenz curve reveals that there exists transference of contributions from the upper to lower classes. But the cumulative percentage of insurance benefit is smaller than that of the number of the insured. It implies that regional medical insurance scheme in Korea has still some inequity in the context of social security principles.

  • Hemophilia is a congenital hemorrhagic disease in which blood clotting is impaired and hemostatic abnormalities occur when even one of the 13 factors required for blood clotting are deficient. Among the 13 factors, hemophilia A (factor 8), hemophilia B (factor 9), and hemophilia C (factor 10), depending on the deficient coagulation factor. A male patient in his 40s diagnosed with hemophilia A visited the dentist at Eulji University Hospital for problems with alveolar bone absorption and periodontal abscess caused by overall chronic tooth inflammation, and showed overall bone absorption and inflammation at the time of initial diagnosis. No complications or bleeding tendency were observed in the rest of the area except for #35 and #36 due to regular visits for 10 years, overall good oral conditions, and no side effects or complications were observed.

  • An orthotopic cardiac transplantation was successfully performed in a 40 year-old Jehovah's witness without use of any blood product. Preoperatively, the patient had been on coumadin to prevent left atrial thrombi and the INR(Internation Normalized Ratio)of prothrombin titre was 2.4. During the operation, cell saver was used for shed blood and aprotinin was admini tered intravenously for platelet function. Total postoperative drainage was 860cc and the lowest hemoglobin was 12.2 gmldl. Postoperative course was complicated by central nervous system infection by wisteria monocytogenes and two episodes of rejection, both of which were effectively treated. The patient is on his 5th postoperative month and doing well.

  • 대사증후군은 비만, 이상지혈증, 고혈압, 당뇨병이나 내당능 장애가 동반되어 나타나는 증후군이다. 근래 들어 우리나라도 점차 비만 인구가 증가함에 따라 대사증후군의 유병률이 빠르게 증가하는 추세를 보여. 대사증후군에 대한 간단한 개념 정리를 하였다. 먼저 대사증후군의 정의와 진단기준을 살펴보았다. 1998년 대사증후군을 명명하고 진안기준을 제시한 WHO 진단기준, NCEP-ATP III 진단기준, 인슐린 저항성 증후군의 진단기준을 살펴보고, 기타 인종에 따른 허리 둘레 기준 및 IDF 정의를 살펴 보았다. 또한 대사증후군과 관련된 여러 인자들도 다시 확인해보고, AHA/NHLBI 진단 기준도 살펴 보았다. 우리나라는 대부분 연구에서 NCEP-ATP III 기준을 적용하고 있는데, 그 내용은 복부 비만 허리둘레 남자 102cm 이상, 여자 88cm 이상, 중성 지방 150mg/dl 이상, HDL-콜레스테롤 남자 40mg/dl 미만, 여자 50mg/dl 미만, 혈압 130/85 mmHg 이상, 공복 혈당 110mg/dl 이상이다. 복부 비만의 경우는 2000년 제정된 WHO 서태평양 지역 기준인 남자 90cm, 여자 80cm 이상으로 적용하고 있다. 다음 치료의 기본 개념을 간단히 언급 하였는데, 가장 중요한 치료는 우선적으로 생활 습관의 개선을 꼽을 수 있으며, 기타 약물요법 및 인슐린 저항성 개선제 등이 있다. 우리나라 에서도 심혈관계 질환과 당뇨병이 점차 사망 원인의 우위를 차지 하고 있으므로 대사증후군을 초기에 진단하고 관리하는 노력이 매우 필요할 것으로 생각되며, 생명보험사도 대사증후군을 하나의 증후군으로 인식하여 대사증후군의 전반적인 이해가 필요할 것으로 생각된다.

  • The Ministry of Health and Welfare in Korea has enforced the oral health promotion program for elderly in Korea. There are the denture delivery program and the fluoride application-scaling program for elderly. Donggu Public Health Center in Daejeon has delivered the fluoride application-scaling program for elderly since the demonstration project in 2009. The official dental hygienists had a prior consultation with Dong-gu branch of Korean Senior Citizens Association in Daejeon. We expanded the program through government office, welfare centers, and nursing homes. The participants were satisfied with the public relations (95.2%), scaling (99.7%), fluoride application (91.5%), toothbrushing education (98.6%), and denture cleaning education (96.6%). After a medial accident with persistent bleeding, the pre-inspection survey about systemic disease and medication was reinforced. The official dental hygienists have agonized over the low participation of the low-income group and the overlap benefit with health insurance benefit of scaling. We suggested it be needed the assessment of the public oral health program to overlap with health insurance benefit.

  • 저온 대기압 플라즈마는 21세기에 들어 생의학 분야에 이용될 수 있는 새로운 도구로서 많은 관심을 받고 있다. 대기압 플라즈마는 고가의 진공 장비를 필요로 하지 않고 저전력 구동이 가능하기 때문에 저비용 구동이 가능하고 방전 장치와 전력공급 장치의 소형화에 매우 유리하다. 특히 저온 대기압 플라즈마는 고온의 전자와 저온의 이온 입자가 공존하는 열적 불평형(thermal non-equilibrium) 상태에 있기 때문에 플라즈마의 저온 특성은 유지하면서도 (${\sim}30^{\circ}C$) 물리/화학적 반응성은 매우 높아 그 응용 분야가 매우 넓다. 플라즈마의 다양한 생의학 분야 응용 가운데 세포의 사멸 유발 또는 생장 촉진, 살균/멸균, 지혈, 상처 치유 등에 저온 대기압 플라즈마가 매우 뛰어난 효능을 보인다는 것이 국내외의 다양한 연구를 통해 밝혀지고 있다 [1]. 20 kHz 정현파로 구동되는 플라즈마 장치를 이용한 암 세포 제거 실험에서 플라즈마 처리 효과를 증대시키기 위해 항체-금나노입자 중합체를 암 세포에 주입시켰다 (그림 1(a)). 그 결과 세포의 사멸율은 74%로서 플라즈마 또는 플라즈마-금나노입자만을 처리한 경우에 비하여 사멸율이 매우 높게 나타났다 (그림 1(b)). 이를 통해 암세포 선택성을 가진 항체-금나노입자 중합체와 플라즈마 처리 기술을 융합한 암 세포의 선택적 사멸 유발 기술의 개발 가능성이 열렸다. 또한 플라즈마 처리를 통해 일어나는 세포의 자멸사 기작이 Cytochrome C의 방출 이후 이어지는 Caspase-3의 활성화 경로와 관계가 있음이 밝혀졌다 (그림 1(c)). 치아 미백은 최근 부상하고 있는 저온 대기압 플라즈마의 새로운 응용 분야이다 [5-6]. 대기압에서 동작하는 헬륨 플라즈마 제트를 미백제(과산화수소)와 함께 발치된 치아에 적용하였을 때 (그림 2(a)) 미백제만을 사용하였을 경우에 비해 치아의 색상 변화가 2배 이상 크게 나타나는 것을 확인하였다 (그림 2(b)). 이처럼 최근 그 범위가 크게 넓어지고 있는 저온 대기압 플라즈마의 생의학 응용 기술의 최적화를 위해서는, 다양한 생의학 응용 분야에 따라 요구되는 플라즈마의 특성 및 응용별 기저 기 작에 대한 이해와 연구가 필요하다.

  • This study was conducted to compare the delivery management including laboratory tests, medication and surgical procedures for the delivery in various medical facilities. Two university hospitals, two general hospitals, three hospitals, two private obstetric clinics, and two midwifery clinics in a large city were selected as they permitted the investigators to abstract the required data from the medical and accounting records. The total number of deliveries occurred at these 11 facilities between 15 January and 15 February, 1989 was 789 among which 606(76.8%) were vaginal deliveries and 183 (23.3%) were C-sections. For the normal vaginal deliveries, CBC, Hb/Hct level, blood typing, VDRL, hepatitis B antigen and antibody, and urinalysis were routinely done except the private clinics and midwifery clinics which did not test for hepatitis B and Hb/Hct level at all. In one university hospital ultrasonography was performed in 71.4% of the mothers and in one general hospital liver function test was done in 76.7% of the mothers. For the C-section, chest X-ray, bleeding/clotting time and liver function test were routinely done in addition to the routine tests for the normal vaginal deliveries. Episiotomy was performed in 97.2% of the vaginal deliveries. The type and duration of fluid infused and antibiotics administered showed a wide variation among the medical facilities. In one university hospital antibiotics was not administered after C-section at all while in the general hospitals and hospitals one or two antibiotics were administered for one week on the average. In one private clinic one pint of whole blood was transfused routinely. A wide variation was observed among the medical facilities in the use of vitamin, hemostatics, oxytocics, antipyreptics, analgesics, anti-inflammatory agents. sedatives. digestives. stool softeners. antihistamines. and diuretics. Mean hospital day for the normal vaginal deliveries of primipara was 2.6 days with little variation except one hospital with 3.5 days. Mean hospital day for the C-section of primipara was 7.5 days and that of multipara was 7.6 days and it ranged between 6.5 days and 9.4 days. Average hospital fee for a normal vaginal delivery without the medical insurance coverage was 182,100 Won for the primipara and 167,300 Won for the multipara. In case of the primipara covered by the medical insurance a mother paid 82,400 Won and a multiparous mother paid 75,600 Won. Average hospital fee for a C-section without the medical insurance was 946,500 Won for the primipara and 753,800 Won for the multipara. In case of the primipara covered by the medical insurance a mother paid 256,200 Won and a multiparous mother paid 253,700 Won. Average hospital fee for a normal vaginal delivery in the university hospitals showed a remarkable difference, 268,000 Won vs 350,000 Won, as well as for the C-section. A wide variation in the laboratory tests performed for a normal vaginal delivery and a C-section as well as in the medication and hospital days brought about a big difference in the hospital fee and some hospitals were practicing the case payment system. Thus, standardization of the medical care to a certain level is warranted for the provision of adequate medical care for delivery.
