유구치의 깊은 우식으로 치수병소가 유발되어 주위 조직에 농양이 형성되는 경우를 자주 보게 된다. 특히 유구치에서 치근분지부 방사선투과성 병소를 흔히 접하게 되는데 이러한 병리적 과정에서 유구치 치근분지부 부근관은 임상적으로 매우 중요한 의미를 지닌다. 영구치의 치근분지부 부근관의 존재에 대한 연구보고는 많고 그 방법 또한 다양하였으나 유구치의 치근분지부 부근관에 대한 연구는 부족하였다. 이에 본 연구는 유구치 치근분지부 부근관의 형태적 특징과 빈도, 개통성을 이해하고자 52개의 치아를 주사형 전자현미경과 진공 흡입하에 염료를 침투시켜 다음과 같은 결과를 얻었다. 1. 주사전자현미경 연구에서 유구치 치근분지부 외면과 내면에서의 부근관의 빈도는 각각 60%, 35%였고, 부근관의 직경은 각각 $11{\sim}107{\mu}m$, $13{\sim}62{\mu}m$였다. 2. 진공 흡입 방법과 염료 침투법을 시행하여 치근분지부에 개통된 부근관을 가지는 유구치의 빈도는 20개의 시료중 50%이었다.

Aims: To describe our institutional experience with high dose rate (HDR) interstitial brachytherapy (IBT) compared with previously reported results on the low dose rate (LDR) practice for head and neck cancer. Materials and Methods: Eighty-four patients with oral cavity (n=70) or oropharyngeal cancer (n=14) were treated with 192Ir HDR-IBT. Seventy-eight patients had stage I or II tumour. The patients treated with IBT alone (n=42) received 39-42 Gy/10-14 fractions (median=40 Gy/10 fractions). With respect to the combination therapy group (n=42), prescription dose comprised of 12-18 Gy/3-6 fractions (median=15 Gy/5 fractions) for IBT and 40-50 Gy/20-25 fractions (median=50 Gy/25 fractions) for external radiotherapy. Brachytherapy was given as 2 fractions per day 6 hours apart with 4 Gy per fraction for monotherapy and 3 Gy per fraction for combination therapy. Results: Four patients were not evaluable in the analysis of outcome. The primary site relapse rates were 23.8% (10/42) and 68.4% (26/38) in patients treated with IBT alone and combination therapy, respectively (p<0.001). Salvage surgery was performed in 19 patients. The 5-year local control rate was estimated at 62% and the disease-free survival (DFS) rate at 52% for all patients. Local control with respect to T1 and T2 tumours was 84% and 42%, respectively. Conclusions: Our present series on HDR-IBT and the previous report on LDR-IBT for head and neck cancer demonstrated similar DFS rates at 5 years (52%). The rate of regional failure in node-negative patients was <20% in both of our series. HDR-IBT offers similar results to LDR-IBT for head and neck cancer.

For years, physicians and anatomists have been interested in the heart that has one functioning ventricle. Various terms have been suggested for this entity including single ventricle, common ventricle, double-inlet left ventricle, cor biatriatum triloculare, and primitive ventricle. In this report, the term "single ventricle" is utilized as suggested by Van Praagh, and is defined as that congenital cardiac anomaly in which a common or separate atrioventricular valves open into a ventricular chamber from which both great arterial trunks emerge. An outlet chamber, or infundibulum, may or may not be present and give rise to the origin of either of the great arteries. This definition excludes the entity of mitral and tricuspid atresia. An 11 year old cyanotic boy was admitted chief complaints of exertional dyspnea and frequent upper respiratory infection since 2 weeks after birth. He was diagnosed as inoperable cyanotic congenital heart disease, and remained without any corrective treatment up to his age of 11 year when he suffered from aggravation of symptoms and signs of congestive heart failure for 2 months before this admission. On 22nd of May 1979, he was admitted for total corrective operation under the impression of tricuspid atresia suggested by a pediatrician. Physical check revealed deep cyanosis with finger and toe clubbing, and grade V systolic ejection murmur with single second heart sound was audible at the left 3rd intercostal space. Development was moderate in height [135 cm] and weight[28Kg]. Routine lab findings were normal except increased hemoglobin [21.1gm%], hematocrit [64 %], and left axis deviation with left ventricular hypertrophy on EKG. Cardiac catheterization and angiography revealed 1-transposition of aorta, pulmonic valvular stenosis, double inlet of a single ventricle with d-loop, and normal atriovisceral relationship [Type III C solitus according to the classification of Van Praagh]. At operation, longitudinal incision at the outflow tract of right ventricle in between the right coronary artery and its branch [LAD from RCA] revealed high far anterior aortic valve which had fibrous continuity with mitral annulus, and pulmonic valve was stenotic up to 4 mm in diameter positioned posterolaterally to the aorta. Ventricular septum was totally defective, and one markedly hypertrophied moderator band originated from crista supraventricularis was connected down to the imaginary septum of the ventricular cavity as a pseudoseptum of the ventricle. Size of the defect was 3X3 cm2 in total. Patch closure of the defect with a Teflon felt of 3.5 x 4 cm2 was done with interrupted multiple sutures after cut off of the moderator band, which was resutured to the artificial septum after reconstruction of the ventricular septum. Pulmonic valvotomy was done from 4 mm to 11 mm in diameter thru another pulmonary arteriotomy incision, and right ventriculotomy wound was closed reconstructing the right ventricular outflow tract with pericardial autograft of 3 x 4 cm2. Atrial septal defect of 2 cm in diameter was closed with 3-0 Erdeck suture, and atrial wall was sutured also when rectal temperature reached from 24`C to 35.5`C. Complete A-V block was managed with temporary external pacemaker with a pacing rate of 110/min. thru myocardial wire, and arterial blood pressure of 80/50 mmHg was maintained with Isuprel or Dopamine dripping under the CVP of 25-cm saline. Consciousness was recovered one hour after the operation when his blood pressure reached 100 /70 mmHg, but vital signs were not stable, and bleeding from the pericardial drainage and complete anuria were persisted until his heart could not capture the pacemaker impulse, and patient died of low output syndrome 320 min after the operation.

This paper is mainly on the rsearch of the prescriptions of "Sanbeon-bang(刪 繁方)". For the research of prescription, investigated "Sanbeon-bang" from the side of symptoms of a disease, number of drugstuffs, table of contents, drugstuffs and acupuncture and moxibustion. With these investigation, made out a few tables, and with these tables made an attempt to understand the whole prescriptions of "Sanbeon-bang". "Sanbeon-bang" is of rich contents in internal medicine. Among internal medicine, related to Oro-Yukgeuk-Chilsang(五勞-六極-七傷) was most abundant. So we can guess "Sanbeon-bang" was a medical book specialized in exhaustion syndromes. It also deals with the Samcho-syndromes, as investigate from medical comments, has the perfect system of prescription in relative. From the investigation of the combination of drugstuffs, ascertained that, the number of simple prescription composed of one drugstuff was 38, combinational prescription composed of two drugstuffs was 9, minor prescription composed of three to five drugstuffs was 47, midum prescription composed of six to ten drugstuffs was 95, major prescription composed of eleven to twenty drugstuffs was 45, and mixed prescription composed over twenty drugstuffs was 1. Mentionable unique prescriptions in internal use were the forms of keeping in mouth. In external use they were fumigants, suppositories, powdered medicines, spraying the granular medication into the nasal cavity and eyedrops. And were abundant in soft extract(ointment) and plaster. In addition, there were the recordings of 18 types of cellulitis, types of incurable cellulitis and curing an illness by a charm. By the way, when comparing "Sanbeon-bang" with "Cheongeum-bang", all of which was quoted a lot in "Oedaebiyo-bang", "Cheongeum-bang" rather took medical comments of "Sanbeon-bang" than prescription. Although there were some prescriptons in "Sanbeon-bang" at the same category, "Cheongeum-bang" took another prescriptions which are more complexed than those of "Sanbeon-bang". In the same way, when comparing "Cheongeum-bang" with "Sonjinin-Cheongeum-bang(孫眞人千金方)", which didn't go through the correction of GyojeongUiseoguk of Bug-Song goverment, "Cheongeum-bang" often didn't take the prescriptions of "Sonjinin-Cheongeum-bang". Hence we can guess, "Cheongeumyo-bang" may have added a lot of prescriptions when undergoing the correction of of GyojeongUiseoguk. The total number of species of drugstuffs in "Sanbeon-bang" from the investigation was 284. The plant drugs were 208 species, the animal were 31 species, the minerals were 19 species and the other were 26 species. The prescriptions related to acupuncture and moxibustion in "Sanbeon-bang" were only moxibustional prescriptions. Which appeared one time per exhaustion and steaming of bone syndrome, Oro-Yukgeuk-Chilsang and Samcho syndrome. Appeared six times in muscle syndromes. But I cannot imagine the original form of acupuncture and moxibustion in "Sanbeon-bang" for deficiency of data.

A clinical study was performed on 75 cases of the esophageal cancer and benign esophageal diseases experienced at Department of thoracic & cardiovascular surgery, School of Medicine, Keimyung University during 3 year period from 1978 to 1982. Of 75 cases of the surgical esophageal diseases, there were 35 patients of the esophageal cancer. 17 patients of benign esophageal stenosis, 10 patients of esophageal perforation, 4 patients of diverticulum. 3 patients of achalasia, 2 patients of congenital T-E fistula, one of upper esophageal web, one of esophageal foreign body, one of leiomyoma and patient of hemangioma. First, esophageal carcinoma was more frequent in men than in women by a ratio of five to one, and the peak incidence occurred in the 5th to 6th decade. Dysphagia was the most common symptom in 88.6 percent of our cases. The tumor was located mostly in the middle & the lower one third [91.4%]. The histological diagnosis was made in 35 cases. The squamous cell carcinoma was the most common [82.9%] and the rest was the adenocarcinoma in the lower one third [17.1%]. Thirty-five cases were operated and resection was feasible in the twenty-five patients [71.4%] with 2 cases of hospital mortality [5.7%]. All but two of the esophageal stenosis were caused by corrosive esophagitis and ages ranged from 7 to 70 years with average age of 32 years. Corrective operations were performed on 17 patients of esophageal stenosis of whom 12 patients had esophagocologastrostomy, 3 patients esophagogastrostomy and in non-corrosive esophageal stenosis one case and esophagoplasty and another case had release of external compression. There was one complication of stenosis of the esophageal perforation were traumatic in five cases, empyema in three cases, caustics in one case and postemetic in one case. 10 patients of the esophageal perforation underwent operation: primary closure in 5 cases, two staged colon interposition in 2, esophagogastrostomy in 1 and closed thoracotomy in 2 cases There were 2 complications of leakage of anastomosis sites in postoperative period. 4 patients of traction type of diverticulum underwent diverticulectomy & 3 patients of achalasia underwent modified Heller`s operation. 2 patients of congenital esophageal atresia had distal tracheoesophageal fistula & underwent one staged operation with the results of one death caused by pneumonia. Upper esophageal web had divulsion through the esophagoscope and foreign body in upper esophagus was removed through cervical esophagotomy. One case of leiomyoma in esophagus had esophagectomy and reconstruction with right colon. And one case of hemangioma in esophagus had esophagectomy & esophagogastrostomy.

The Recommended Dietary Allowances(RDAs, Nutrient standards), dietary guidelines, and food guides, each define aspects for a healthy diet in different ways. The RDA and food guide for Koreans were first established in 1962 by the Food and Nutrition Committee of the Korea FAO Association. The committee released the RDA and suggested ways to intake the recommended nutrients. Every five years, the committee has added more data and released revisions. The latest edition of the RDA is the 6th revision. In the beginning, the concept of basic food groups was emphasized as basic data for planning means based on RDA. In the 5th revision, the basic food groups and dietary guideline for public health from the Ministry of Health and Welfairs(December, 1990) suggests that, 1) Eat a variety of foods with a recommended fat intake equaling or less than 20% of total calories ; 2) Maintain ideal body weight and prevent obesity ; 3) Eat foods low in salt. Salt intake should not exceed 10g ; 4) Do not drink too much ; 5) Eat regularly and enjoy meals. After these guidelines were established, the first nutritonal education efforts guidelines were developed in 1984. Despite broad possibilities for application, they had limited use, mainly as a nutritional assessment and food balance sheet preparation. They were not well utilized in public nutritional education and nutritonal policy through the media because of the weakness of the government's food and nutriton policy. Also a lack of administrative support and dietitians in the health department and administrative organizations was partly to blame. In regard to public health and nutrition status, life expectancy has increased 10 years since the 70's and the elderly population increased threefold in 1995 compared to 1960. The common causes of death in 1996 by 19 Chapters classification, were first disease of the circulatory system ; the second, neoplasms ; the third, external causes fo mortality ; the forth, diseases of the digestive system ; and the fifth, respiratory system diseases, In food intake, grain and complex starch intake has decreased while fruit and animal foods have considerably increased. Therefore, energy from carbohydrates has decreased while energy from protein and fat has increased. Energy intakes from protein, fat and carbohydrates were respectively 12.5, 7.2 and 80.3% in 1969 but 16.1, 19.1 and 64.8% in 1995. 62.9% of the householes had the fat energy less than 20%, while 37.1% had the fat energy above 20%. The only intakes of vitamin A and calcium were below RDA levles. Therefore, nationwide attention should be focused on public nutriton education and public activities with supplementation of the RDAs, according to the food guide and the dietary guideline.

CdS 양자점 입자는 특정 파장의 빛을 방출하는 반도체 나노 결정으로 이러한 광학적 특성 때문에 질병 진단 시약, 광학기술, 미디어 산업 및 태양전지와 같은 다양한 분야에서 응용되는 물질이다. 방출하는 빛의 색은 입자의 크기에 의존하기 때문에 CdS 양자점 입자의 크기 및 크기분포를 정확하게 분석하는 것이 필요하다. 본 연구에서는 CdS 양자점 입자를 감마-선 조사법(${\gamma}$-ray irradiation method)을 이용하여 합성하고, 크기 및 크기 분포도를 결정하기 위하여 침강 장-흐름 분획법 (SdFFF)를 이용하였다. 침강 장-흐름 분획법을 이용한 CdS 양자점 입자의 정확한 분석을 위하여 분석조건의 최적화(유속, 외부장 세기, field-programming)에 대하여 조사되었다. 투과 전자 현미경(transmission electron microscopy, TEM)으로 확인된 단일 입자의 크기는 ~4 nm 였으며, 단일 입자의 응집으로 생성된 2차 입자 크기의 평균은 159 nm로 확인되었다. 첨가된 입자 안정제의 농도가 증가할수록 CdS 양자점 입자의 크기가 감소하는 경향성을 확인하였다. 침강 장-흐름 분획법, 투과 전자 현미경, 그리고 동적 광 산란법(dynamic light scattering, DLS)으로 결정된 CdS 양자점 크기는 각각 126, 159, 그리고 152 nm 였다. 본 연구의 결과로 침강 장-흐름 분획법은 비교적 넓은 크기분포를 갖는 다양한 종류의 무기입자의 크기 및 크기 분포도를 결정하는데 유용한 방법임을 확인하였다.
