애성이란 음성의 질적 변화를 의미하는 것으로 이는 후두의 가장 대표적인 주 증상이다. 애성의 원인으로는 현재까지 알려져 있는것만 해도 약50 여종이 있다고 하며 그중 virus에 의한 상기도 감염증이 가장 많은 비율을 차지하고 있는 것으로 알려져 있고, 후두결절 및 풀립, 후두마비, 후두암, 후두유두종, 후두결핵등의 순으로 발생하는 것으로 알려져 있다. 최근 저자들은 본원에 입원중인 환자로서 애성 때문에 본 이비인후과로 진찰의뢰된 환자중 비교적 보기드문 질환과 동반된 애성환자 4예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 증예1. 29세 남자로서 교통사고로 후두부에 외상을 입은후 1 달만에 애성이 발생. 후두경 소견상 좌측성대의 paramedian paralysis 및 arytenoid cartilage의 전위가 인정되었음. 증예2. 53세 남자로서 clonorchis sinensis로 일반외과에서 전신 삽관마취하에 choledochostomy를 시행한 6 일후에 애성이 발생. 후두경 소견상 좌측성대의 median paralysis가 인정되었음. 증예3. 56세 남자로서 Aortic Aneurysm으로 내과에 입원한 환자로 입원전 3개월부터 애성이 발생. 후두경 소견상 좌측성대의 intermediate position paralysis 및 arytenoid cartilage의 전위가 인정되었음. 증예4. 74세 남자로서 Bronchogenic Ca.로 내과에 입원중인 환자로 입원 3년전부터 애성이 발생. 후두경 소견상 우측성대의 paramedian paralysis가 인정되었음

This study was carried out to understand the macroscopic aspects of the digestive system symptoms occurring after taking oriental herb complex decoction as observing morphological changes in esophagus, stomach and duodenal bulb by endoscopy of upper gastrointestinal tract when these symptoms developed. The subjects of this study were 46 patients (male 22, female 24, mean age : $54.72{\pm}14.26$ years) who were chosen among ones who took oriental herb complex decoction for medical care and developed symptoms related to the gastrointestinal tract while taking an oriental herb decoction, which were assumed that the digestive symptoms were newly developed because of administration. The subjects were given morphological examination by endoscopy of the upper gastrointestinal tract. As a result of the endoscopy operated due to the digestive symptoms developed during the administration of oriental herb decoction, there were 2 cases of esophagitis, 5 cases of acute gastritis, 1 case of chronic gastritis A type, 15 cases of chronic gastritis B type, 1 case of duodenitis, 1 case of gastric ulcer, 1 case of gastric polyp, 2 cases of intestinal metaplasia, 1 case of gastric ptosis and 17 cases of normal findings which didn't have any abnormality macroscopically with endoscopy. With regards to the patients who complained of the digestive symptoms after taking oriental herb decoction, it has been found that the symptoms occurred as the oriental herbal medicine taken by the patients who had the digestive symptoms at ordinary times influenced on the gastrointestinal tract. Especially, many of them were had chronic gastritis and functional dyspepsia in the past. The disease accompanying macroscopic lesions at endoscopy which occurred due to the oriental herb decoction as direct cause, was acute gastritis, and it was the prescription to cure the pains and inflammations of skeletomuscular disease.

Background and objectives : Social phobia is a nervous anxiety characterized by one or more constant fear in social activity or specific situation which causes serious damage to individual's social functions leading to chronic functional impairment when it is untreated. The objective of this study is to report a new finding of a possible subtype of social phobia according to a case survey and study of sufferers found via online support group. Methods : A single case review using survey and interview on patient was employed. Following a no-treatment baseline period for examination and interview, biweekly acupuncture treatment with interview for in-depth examination was delivered for 6months. Also, for in-depth investigation of peripheral vision phobia, survey questionnaire was done by the members of a Korean support group on on-line social group forum. Result : A new type of social phobia which has not yet been reported nor mentioned in any journals, namely called 'peripheral vision phobia' has been identified. Biweekly acupuncture treatment reached a comfort state of mental status on one case of patient with social phobia. Limitation : Due to the shift of environment on patient's part, the termination of the school session at where the phobia occur the most, the reoccurrence of the phobia is yet to be examined. Also, the generalization of the new type of phobia as a subtype only by reviewing one case alone with survey interview of on-line social group has limitation. Conclusion : The result of the case review suggests that 'peripheral vision phobia' is strictly concentrated on malfunctioning of peripheral vision without functional or organic hindrance of pupils or of any parts of eyes including eye muscles due to peripheral vision phobia. PVP is similar to social phobia and it may be a subtype of social phobia, however, since etiology, diagnosis, medical treatment methods are under researched, investigation is yet to be done.

현재, Covid-19의 밀접접촉자를 찾아내어 진단검사를 통해 Covid-19 확산을 차단하고 있다. 하지만 확진자의 잠복 기간이 2주가 되고, 확진자의 동선을 추적하여 접촉자를 찾기에 많은 인력과 시간, 비용이 소요된다. 특히, 확진자의 수가 증가할수록 접촉자를 찾아 사전에 차단하는 비용이 기하급수적으로 증가하여 한계점을 가진다. 접촉자를 찾기 위해 전 국민이 상점이나 식당 등 편의시설을 방문할 때마다 전자출입명부를 기록해야 하는데 이는 개인의 위치 정보에 대한 프라이버시 침해 가능성이 높다. 본 연구에서는 자신의 위치와 시간을 실시간으로 저장하고, KDCA에서 수집된 감염자의 동선 정보를 다운받아 겹치는 지점이 있을 경우에 사용자에게 통지하여 사전에 진단검사를 유도하는 시스템을 설계하고자 한다. 제안 기법은 상점을 방문할 때 전자출입명부를 기록해야 하는 번거로움을 해결하면서 개인정보를 사전에 KDCA에 제공하지 않아 프라이버시 침해를 차단할 수 있다.

A case of Vanishing lung of right entire lung field in a man of 36 years of age was encountered at Dept. of Chest Surgery of Chonnam University Hospital. His chief complaints were cough, severe dyspnea and chest pain for about 14 years. Right pneumonectomy was done and gross finding was multiple chambered cysts of the right lung with thin epithelium. The review of the literatures was also done.

A rare case of a fused teeth on the side of upper left third molar was observed from a 28 years old Korean male. The characteristics were as follows: 1)The upper third molar fusrd with the suppernumerary tooth .2)The crown part of the fused teeth were separated and the root were fused. 3)On the x-ray finding. the pulp chamber was two , but it had only one pulp canal.

This paper presents an algebraic approach for finding a dynamic state feedback controller when the linear multi-input system with delays in both state and input is controllable. In the time-delay case, controllability of the system does not always imply that system is cyclizable. Therefore, reduced order augmentation systems which is cyclizable as the time-varying case are considered. It is possible to construct feedback contorl systems by using single-input methods.

Myoepithelioma of the trachea is an extremely rare disease. The neoplasm shows histologic features identical to those described in myoepithelioma of salivary glands. The myoepithelioma cells demonstrate the numerous myofilament, desmosomal cellular attachment, cytoplasmic glycogen and pinocytotic vesicles. In immunohistochemical study, myoepithelioma cells show the positive antibody reactions to actin, keratin, vimentin and S-100 protein. A case of myoepithelioma arising from trachea in the seventy-two-year old male diagnosed by microscopic finding and immunohistochemistry is presented.

Optimal screening procedures for improving outgoing product quality based on correlated normal variables are presented. The performance variable and the screening variables are assumed to be jointly normally distributed. These procedures do not require specialized tables, and closed-form solutions are obtained for the case of one-sided specification. Methods for finding optimal solutions for the case of two-sided specifications are also considered.

Given a prime number p and a natural number m not divisible by p, we propose the problem of finding the smallest number r₀ such that for r ≥ r₀, every group G of order p^rm has a non-trivial normal p-subgroup. We prove that we can explicitly calculate the number r₀ in the case where every group of order p^rm is solvable for all r, and we obtain the value of r₀ for a case where m is a product of two primes.
