저위교합이란 능동적 맹출기 동안이나 이후 해당치아의 교합면 방향으로의 성장이 멈추어 다른 치아들보다 하방에 존재하는 것을 말한다 저위교합치의 결과로 침하치의 만기잔존, 부정교합, 증가된 치아우식 감수성과 치주질환의 가능성, 계승치의 이동 등이 나타날 수 있다. 따라서 조기진단 및 적절한 처치가 필요하다. 저위교합치의 치료는 저위교합 정도나 후속 영구치의 발육정도에 따라 보존에서 발치까지 다양하다. 영구 계승치가 없거나 부분적인 침하치가 치주적으로 건전한 경우, 공간문제를 발생하지 않는 경우 보존적인 접근이 추천되기도 한다. 그러나 계승치가 존재하고 맹출이 지연되는 경우, 국소적인 염증반응과 관련되는 경우 교정적인 치료가 필요한 경우에는 발거가 필요할 수도 있다. 특히 저위교합된 유구치의 상방으로 인접치가 경사되어 악궁장경에 문제를 초래할 위험이 있는 경우 외과적인 발치가 필요할 수도 있으며 경사가 심한 경우 발치를 위한 외과적 접근이 힘들 수 있다. 심하게 경사된 인접치로 인하여 저위교합치의 외과적 발거가 힘들 환아에서 가철성 교정장치를 이용하여 공간확보를 진행 하였으며 보다 용이하게 치아를 발거할 수 있었다. Infraclusion may be defined as teeth that stop their relative occlusal movement in the dental arches during or after the period of active eruption and then remain under the occlusal plane. Delayed exfoliation, malocclusion, increased susceptibility to dental caries and periodontal disease of both the neighboring teeth and retained molar, and dislocation of' the successor are the consequencces of infraclusion of primary molars. Therefore, early diagnosis and appropriate treatments are necessary. The therapeutic approach of' the infracluded teeth varied from preservation to extraction. The teeth with simple infraclusion without any signs of interference with occlusal and jaw development may be examined periodically with fellow-up check and radiographically. However, if the infracluded tooth interferes with normal eruption of successor or shows any sign of delayed resorption, or the tipping of adjacent teeth or supraeruption of op-posing teeth is expected, the teeth inflicted should be extracted and appropriate measures should be provided in order to maintain the normal development of occlusion and dentition. The adjacent teeth which have been collapsed over a infracluded deciduous teeth can disturb the arch length perimeter. In such cases, surgical approach might be necessary, although it would be difficult when teeth are severly leaned. However, an easier surgical access have been obtained by space regaining procedures, in young patients whose arch length has been shortened due to the infracluded teeth.

A model gas turbine engine was designed and developed. The design point was set up through the cycle analysis to design the combustor which is the kernel of an engine. The length, diameter of the combustor and diameter and number etc. of an air inlet hole was designed based on the way suggested by Kunio Suzuki. The designed result is checked by a combustion intensity and a mean residence time if it was designed suitably or not. The design point of the model of the 3kW gas turbine engine was set up in conditions of outlet temperature of the combustor 900K, the rotational speed of the compressor 110,000rpm, the ratio of pressure 1.57, the air flow rate 0.07 kg/s which is supplied into the combustor. The designed specifications of the combustor are as follows : the whole length of the combustor liner 147mm, the diameter 52mm, the diameter of casing 67mm, the hole diameter - the primary zone 5.25mm, the secondary zone 4.64 mm, the dilution zone 7.32mm.

This study was conducted to evaluate the hospital foodservice management practices in Seoul and to suggest the guideline for the effective foodservice management. Questionnaire survey method were used in this study. Questionnaire were administered to dietitians in twenty hospitals. Data were analyzed for frequency, percentage, χ^(2)-test, and one-way ANOVA using SAS PC Package program. The results were summerized as follows : The number of dietition were less than the required number for efficient foodservice. Centralized foodservice method was adopted in most hospitals and conventional foodservice system was taken in all the hospitals. The space of a kitchen and a dining room were confined and sanitary facilities and working condition revealed problems. Equipped facilities in surveyed foodservice operations were assessed as the insufficient condition, especially, efficient facilities such as a cutting machine were scarecely make up.

Purpose: The purpose of this study was to compare the efficacy of heparin flushing and normal saline flushing in maintaining patency of central venous catheters(CVCs), and to investigate relative risk factors of CVCs' occlusion. Method: A total of 159 patients who had been inserted with CVCs were included in the department of hemato-oncology of S hospital. The heparin group consisted of 74 patients with 10u/ml diluted heparin flushing from 23 November 2004 to 15 January 2005, and the normal saline group consisted of 85 patients with 0.9% normal saline flushing from 19 January to 31 March of 2005. Result: The heparin group was significantly different from the normal saline group in CVCs' occlusion. The normal saline group offered a much longer survival duration of CVCs' patency than the heparin group. Potential bleeding signs (PT, aPTT) had no significant differences. In multivariate analysis, 0.9% normal saline (hazard ratio 0.50), chemo port (hazard ratio 3.38), and no administration of TPN (hazard ratio 0.25) were the significant factors for occlusion of CVCs. Conclusion: For maintaining the patency of CVCs, 0.9% normal saline flushing are expected to be effective in reducing drug incompatibilities, lessening the bleeding tendency and improving cost effectiveness .

Background: To evaluate the articles published by Korean endoscopists in the MEDLINE between 1971 and 2014. Methods: A systematic literature review was conducted using the MEDLINE database(through PubMed). The searching keyword was `endoscopic submucosal dissection`. Analyzed parameters included the total number of articles, journal, institution, country, published year, and number of citation. The number of citation was measured by the Institute for Scientifi c Information Web of Knowledge-Web of Science (SCIE) database on July 2014. Results: A total of 1791 papers were searched in 244 journals (941 articles in SCI journal, 525 articles in SCIE journal, and 325 non-SCI, SCIE articles). Among the total articles, Korea`s contribution was 15.6% (n=304) and ranked 2nd in the world.The journals in the order of number of articles were as follows; Endoscopy (n=206), Gastrointest Endosc (n=187), Dig Endosc (n=137), Surg Endosc (n=134), and World J Gastroenterol (n=82). Among the literatures written by Korean authors, the journals in the order of number of articles were as follows; Surg Endosc (n=38), Clin Endosc (n=35), Gastrointest Endosc (n=31), and Endoscopy (n=24). The mean citation number was 12.1 ± 25 in the total literatures. However, the number was decreased in the articles written by Korean authors; 7 ± 14.2. The most cited article written by Korean authors was `Therapeutic outcomes in 1000 cases of endoscopic submucosal dissection for early gastric neoplasms: Korean ESD Study Group multicenter study` published in 2009, which was cited 153 times until now. Conclusions: Korea`s contribution to endoscopic submucosal dissection has been increasing.
