Dong Hae Chung,Jae Yeon Seok,Yoo Seung Chung1,Eun Mee Oh1,Jung Won Ryu1,Young Don Lee1 대한갑상선-내분비외과학회 2015 The Koreran journal of Endocrine Surgery Vol.15 No.1

On ultrasonography, medullary thyroid carcinoma (MTC) shows hypoechogenicity, an irregular margin, a predominantly solid composition, and microcalcifications, similar to those observed in papillary thyroid carcinoma (PTC). MTC presenting as a cystic lesion is rare, and endoscopic thyroidectomy can be performed for benign thyroid masses and early stage PTC, however it is inappropriate for MTC regardless of cystic change. The authors report a case of cystic MTC found after endoscopic thyroid lobectomy and provide a review of the literature on this topic.

Jinhae would be a important city of military facilities for naval. Owing to the background of this times, Jinhae focused on military facilities has remained a lot of modern buildings such as government and public offices, stores, house buildings and it has merited the pursuit of learning about the formation of city in modern and the features of modern buildings. Consequently, this paper will be acquired to a first-data about modern buildings under the current situation of loss and transformation and studied to the speciality of the naval city by inquiring the process of formation in Jinhae, executing the literature analysis and the example investigation.

慶北 漆谷郡 東明 貯水地에서 採集한 淡水魚에서의 吸蟲類 被囊幼蟲 奇生狀의 變動

李元碩,鄭東一,崔東翊 慶北大學校 醫科大學 1991 慶北醫大誌 Vol.32 No.3

1989年 4月부터 同年 9月까지 慶北 漆谷郡 東明貯水池에서 採集되는 各種 淡水魚에서 吸蟲類 被囊幼蟲의 寄生狀을 調査하여 1983年 同貯水池에서 調査한 成績과 比較하였다. 東明貯水池에서 採集된 魚種은 붕어(Carassius carassius), 납지리(Paracheilognathus rhombea), 참붕어(Pseudorasbora parva), 피래미(Zacco platypus)의 4種으로 1983年 少數 採集되었으던 몰개(Gnathopogon atromaculatus)는 採集되지 않았다. 1983年에는 5種의 淡水魚중 2種 즉 몰개와 참붕어에서 2種의 吸蟲類 被囊幼蟲, 肝吸蟲과 Exorchis oviformis 被囊幼蟲을 檢出할 수 있었다. 물개와 참붕어에서의 肝吸蟲 被囊幼蟲의 寄生率은 各各 7.4%와 15.6%였고 魚肉 1g當 被囊幼蟲數로 나타낸 그 寄生程度는 各各 0.1個와 0.2個였고 E.oviformis 被囊幼蟲의 寄生率은 各各 18.5%와 26.7%, 그 寄生程度는 各各 0.2個와 0.4個였다. 그러나 이번 調査에서는 全魚種에서 吸蟲類 被囊幼蟲을 전혀 찾아볼 수 없었다. In order to compare the infestation status with larval trematodes with that in 1983, fresh-water fish were collected in the Tongmyung pond from April to September, 1989, and examined for the presence of the encysted larvae of digenetic trematodes. Four species of fresh-water fish, the crusian carp, Carassius carassius, the flat bitterling. Paracheilognathus rhombea, the southern top-mouthed minnow, Pseudorasbora parva and the pale chub, Zacco platypus, were collected in the pond. Gnathopogon atromaculatus which had been collected in 1983 was not collected in 1989. In 1983, two species of the metacercariae, Clonorchis sinensis and Exorchis oviformis, were demonstrated from G. atromaculatus and P. parva. The incidences of C. sinensis cyst in G. atromaculatus and P. parva were found to be 7.4% and 15.6%. The intensity of infestation, the numbers of metacercariae per gram of flesh, were 0.1 and 0.2, respectively. The incidences of E. oviformis cyst in G. atromaculatus and P. parva were 18.5% and 26.7% with the intensity, 0.2 and 0.4, respectively. However, no larval trematodes was demonstrated from fresh-water fish collected in 1989.

This paper deals with a systematic approach to GA-PI Controller design for static VAR compensator(SVC) using genetic algorithm(GA) to improve system stability. Genetic algorithms(GAs) are search algorithms based on the mechanics of natural selection and natural genetics. To verify the robustness of the proposed method, considered dynamic response of terminal speed deviation and terminal voltage by applying a power fluctuation. Thus, we proved usefulness of GA-PI controller design th improve the stability of single machine-bus with SVC system.

유년기 Ⅲ급 부정교합자에서 이모장치의 치료 효과에 관한 연구

남동석,서정훈,양원식,장영일 대한치과교정학회 1998 대한치과교정학회지 Vol.28 No.4

본 연구는 유년기의 하악 전돌성 III급 부정교합자에게 이모장치를 착용하여 치료하였을 때 나타나는 변화를, 보다 적절한 대조군을 이용하여 알아보고자 시행하였다. 이모장치를 이용하여 치료한 하악전돌의 골격성 III급 부정교합자중에서 치료 시작 시기가 약 7세경인 29명(남자 14명, 여자 15명)을 실험군으로 하였고, 비슷한 연령으로 골격적 상태가 유사하며 어떤 형태의 교정치료도 받지 않은 III급 부정교합자 21명(남자10명, 여자11명)을 대조군으로 하였다. 2년의 관찰 기간을 거쳐, 초기 및 2년 후의 두부방사선사진을 계측 분석하여 그 변화량을 비교한 결과 (t-test, p<0.05) 다음과 같은 결론을 얻었다. 1. 이모장치를 착용하지 않은 대조군에서는 악골의 부조화가 개선되지 않고, 심화되는 방향으로 성장하였다. 즉, 치료하지 않은 하악 전돌성 III급 부정교합자는 성장에 의해 개선이 일어나지 않음을 나타내었다. 이모장치를 착용한 실험군에서는 전후방 골격 부조화가 감소하였으며, 하악 전돌감이 개선되었다. 2. 두개저와 상악골의 성장은 이모장치에 의해 유의한 변화를 보이지 않았다. 3. 이모장치의 하악골 성장억제 효과를 인정할 수 없었으나, 하악골의 성장 방향의 변화 및 성장 형태의 변화가 관찰되었다. 4. 이모장치 착용시 수직적 성장 경향이 증가하였다. 5. 연구 성적을 종합적으로 검토한 결과, 이모장치의 주된 치료 기전은 하악골의 후하방 회전과 변위이며, 성장 방향과 형태의 변화가 부분적으로 기여한다고 볼 수 있었다. 위의 결과를 종합해 보면 이모장치의 치료효과는 하악 골격 성장의 억제효과라기 보다는 하악골의 후방 회전과 변위에 의한 것이며 성장기 하악 전돌성 III급 부정교합자에서 골격 부조화의 개선 및 전돌감 해소에 유용한 장치라고 생각된다. The purpose of this study was to investigate the changes in the craniofacial skeleton subsequent to chincap therapy in the juvenile skeletal Class III malocclusion with more appropriate control samples. The experimental group consisted of 29 Korean children(14 males, 15 females) who had skeletal Class III malocclusion with prognathic mandible and were undergone chincap therapy from the beginning of treatment. The control group was composed of 21 Korean children(10 males,11 females) who had no orthodontic treatment, but with similar skeletal discrepancies to experimental group. Lateral cephalometric radiographs at the age of 7, and 2 years later were analyized and compared with student`s t-test(p<0.05). The results of this study were as follows; 1. The control group without chincap therapy had not shown any improvement of the skeletal discrepancies, but had grown to be much severe. This means that the untreated Class III patient with prognathic mandible would not be corrected by growth. For the experimental group with chincap therapy, the anterior-posterior skeletal discrepanices and mandibular prognathism were both improved. 2. Neither significant restraint nor acceleration of growth was found in the cranial base and maxilla by chincap treatment. 3. The inhibition of mandibular growth could not be accepted, but the changes of the direction of growth and morphological changes were found. 4. Vertical growth tendency was increased with chincap therapy. 5. When putting together the results of the analyses, it seems to be the rotation and displacement of the mandible that the major treatment effects of chincap are. The changes of the direction of growth and the morphological changes also seems to contibute to the treatment effect partly. In summary, the chincap doesn`t restrain the mandibular growth. But, it is considered as a useful treatment modality for correction of skeletal discrepancies and reduction of mandibular prognathism in growing Class III patients with madibular prognathism.

교정 치료 환자에 있어 항균 varnish 처치 전후의 타액 내 Streptococcus mutans 균주의 변화에 관한 연구

남동석,양원식,장영일,서정훈,정종평,김태우 대한치과교정학회 1994 대한치과교정학회지 Vol.24 No.3

Dental caries is one of the most prevalent dental diseases in Korea and its prevention is very important in orthodontic therapy. For the cleansing action of saliva itself and/or tooth-brushing is lowered in patient with fixed orthodontic appliance, oral hygiene of the patient becomes worse, which provides more favorable environment for micro-organisms. Chlorexidine, one of the series of bisguanide, has been reported to be strong antimicrobial agent and very effective on Streptococcus mutans. The purpose of this study is to evaluate the possibility of chlorhexidine as a anticariogenic agent in fixed orthodontic therapy. We used the varnish containing chlorhexidine as a main ingredient for the chemical control of salivary S.mutans in patients with fixed appliance therapy. We applied the varnish containing chlorhexidine on the labial and interproximal surface of the teeth before bonding and banding teeth of our patients(N=20) and compared to control group patients(N=20). Before the application of chlorhexidine varnish and four times periodically after the completion of fixed appliance set-up, we sampled saliva of both group patients and incuvate S.mutans for 24 hours. In the culture study of sampled saliva, counting the number of S.mutans colonies, we founded as follows : 1. In patients with fixed appliance therapy, the risk of dental caries increase when it compared to that of preorthodontic treatment ; The number of salivary S.mutans increase in patient's oral cavity. 2. The experimental agent that contain chlorhexidine is effective to reduce the number of salivary S.mutans. 3. For the effect of this agent is not ever-lasting, periodical application is needed, and additional study for economical interval and number of application is needed.
