상갑선 설관낭종 및 설관루는 선천성 경부질환중 가장 많은 빈도를 차지하는 질환으로 설저에서 강상선에 이르기까지 갑상선설관의 경로중 어디서나 발견될 수 있으며, 다른 종양이나 낭종과 구별이 용이치 않을 경우가 많다. 단순한 낭종 또는 결절로 오인되어 근치절제가 되지 않았을 경우 흔히 재발을 잘 일으키며 또한 갑상선 조직이 포함될 수 있다. 경우에 따라서는 이것이 유일한 갑상선 조직일 수 있어 절제시에 더욱 신중을 요한다. 저자는 최근 2년동안 본병원 이비인후과에서 낭종또는 루를 가진 갑상선설관 환자 8명을 수술적 요법으로 치료하였던바 이에 대한 문헌고찰과 아울러 보고하는 바이다.

Over the period between October 2005 and February 2007, herbal medicine was administered to the patients coming to Dr. Cha Oriental Medical Clinic. As regards the prescription administered to children patients for treating their growth deficiency, Eukmigihwang-tang related to the kidney, the congenital factor, Bojungikgi-tang related to the spleen, the acquired factor. So I administered Eukmigihwang-tang plus Bojungikgi-tang(a union of both herb-remedy: Eukmigihwang-tang and Bojungikgi-tang) The results were obtained as follows. 1. The youngest is six years old, the oldest is thirteen years old. 2. A ratio of male and female children was same. 3. It was shown to be a greater increase than the average value of growth surveyed by the National Statistical Office. 4. It is considered that EukmigihwangtangHapBojungikgitang is effective on child growth.

Age structure and growth of white croaker Pennahia argentata were estimated an analysis of otoliths. Fish specimens were collected from the Southern Sea of Korea from January to December 2018. A thin section method was used for age determination because otoliths of white croaker are oval in shape and large in size. Otoliths were cut vertically into 0.4-0.5 mm thick sections with an electric saw (Micracut 125). Monthly changes in the marginal index indicated that rings (opaque zone) were formed once a year in August. The estimated von Bertalanffy growth equation estimated by a non-linear regression were L∞=34.71 (1-e0.38(t+0.80)). In the present study, the oldest female was 8 years old and the male was 7 years old.

The most prevalent and oldest type of structure is unreinforced masonry (URM) structures; URM walls are still a widely used construction material in India and many other developing countries due to their simplicity, ease of construction, economic sustainability, and ability to be built with locally available materials. URM walls are significantly weak while carrying lateral loads. The poor performance of URM walls during earthquakes has necessitated investigating an effective method for strengthening a newly built masonry building or retrofitting an old structure. Wire mesh, being cost-effective and easily available, satisfies the requirements to strengthen new and old URM buildings. The use of wire mesh to strengthen and retrofit the URM structure is simple to use, quick to construct, and inexpensive, especially in developing nations where heavy machinery and highly qualified labour are lacking. The current paper reviews the effectiveness of steel wire mesh as a reinforcing material for enhancing masonry strength. The finding gave encouraging results for the field application of wire mesh.

The Japanese fishery management system has been established on the basis of various experience accumulated over many years. The fishery management system in Japan, one of the oldest fishery management systems in the world, is aimed at ensuring comprehensive utilization of the water surface and developing fishery productivity, by giving protection of the breeding environment of aquatic animals and plants, enabling the appropriate use of fishery grounds, preventing and solving disputes over fishery grounds and making other fishery adjustments. Japanese Fishery Law has been changed largely into (1) The Feudal Era(to 1900), (2) The Oldest Fishey Law(1901~48), (3) Current Fishery Law(1949 to present). Japanese fishery legislation is designed as a single package combining coastal, offshore and distant-water fisheries. During the period of the old fishery law, numerous conflicts arose over the joint use of fishing grounds and fish stocks. Such conflicts occurred among users of the same gear as well as between users of different gears or of different sizes of fishing craft. Large scale conflict sometime occurred between neighbouring fishing communities due to a lack of fairness in principle and coordination in practice. Therefore, the new fishery law enacted in 1949. This law was designed primarily to realize the most effective and rational use of fishing grounds and fishery resources, the basic philosophy being that, through democratic organization by fishermen themselves, productivity would be stimulated and incomes and living standards eventually improved. Nowadays, Community Based Fisheries Management through democratic organization by fishermen themselves have to enforce at coastal fisheries. This Community Based Fisheries Management manage to fishery resources by fishermen themselves and harvest in collaboration with that resources. Therefore, this paper is intended to briefly to describe the entire system and the historical development of Japanese fishery legislation in order to assist in reform of our country fisheries management regime.

During the period from 1958 to July 31, 1980, there were 1764 Cardiovascular Surgical cases consisting of 1166 congenital and 598 acquired lesions in the Department of Cardiothoracic Surgery, Seoul National University Hospital. For 1764 cases 1162 open heart surgery and 602 conventional operations were performed. Among 1166, congenital lesions 266 adult cases were found. Adult cases occupy 15.1% of the total cases consisting of 24.5% of acyanotic and 19.9% of cyanotic group. Over all operative mortality of adult cases was 6.8% compared with 12.4% of total cases. Left over congenital cardiovascular anomalies in Korea can be safely operated at the present time. The oldest operated patient among adult congenital cardiovascular anomalies was 57 years old female atrial septal defect case. For 1162 cases open heart surgery bubble oxygenators were utilized except 2 membrane oxygenators. Various kinds of bubble oxygenators have been used but recently Shiley**** oxygenators are being used exclusively with satisfactory results.

We present the result of our investigation on the impact of the low Solar abundance of Asplund and collaborators (2004) on the derived ages for the oldest star clusters based on isochrone fittings. We have constructed new stellar models and corresponding isochrones using this new solar mixture with a proper Solar calibration. We have found that the use of the Asplund et al. (2004) metallicity causes the typical ages for old globular clusters in the Milky Way to be increased roughly by 10%. Although this may appear small, it has a significant impact on the interpretation for the formation epoch of Milky Way globular clusters. The Asplund et al. (2004) abundance may not necessarily threaten the current concordance cosmology but would suggest that Milky Way globular clusters formed before the reionization epoch and before the main galaxy body starts to build up. This is in contrast to the current understanding on the galaxy formation.

Gliofibroma is an extremely rare biphasic tumor with an astrocytic and benign mesenchymal component, which commonly occurs within the first two decades of life. The exact biological behavior of the tumor is not fully understood. Therefore, it is not listed as a distinct entity in the current World Health Organization classification of central nervous system tumors. Here, we describe a rare case of gliofibroma, which was located on the medial temporal lobe in a 61-year-old woman. Preoperatively, we misdiagnosed it as a meningioma because it was a well-demarcated and well-enhanced extra-axial mass with calcification and bony destruction. On the histopathological and immunohistochemical examination, the tumor consisted of a mixture of glial tissue and mesenchymal tissue and it was finally diagnosed as a gliofibroma. To our knowledge, this case of intracranial gliofibroma is in the oldest patient ever reported.

Extended porta hepatis dissection and hepatic portojejunostomy was performed on 14 biliary atresia patients during last 13 years by a single surgeon. The average age at operation was 68 days(range from 37 days to 98 days). The patients were admitted for 8 weeks postoperatively for administration of parenteral antibiotics. There was one operative mortality due to acute hepatic necrosis. Among 13 patients remaining, 12(92.5 %) became chemically jaundice-free within 36 weeks postoperatively(average 16.8 weeks). the earliest 8 weeks, and in one patients jaundice persisted. Five(38.5 %) patients developed cholangitis after operation. Among jaundice-free patients, one patient died of unrelated disease 2 years after hepatic portojejunostomy, who underwent left lateral segmentectomy because of a biloma. Eleven survivors(78.6 %) are jaundice-free. The oldest one is 13 years old, enjoying a normal life. The mean period of follow-up is 7 years and 3 months.
