Venous malformation with phleboliths is uncommon cause of unilateral parotid swelling. The clinical and radiographic appearance of venous malformation with phleboliths may masquerade as sialolithiasis. A 49-year-old female complained about unilateral parotid swelling for 6 years. Preoperative evaluation including computed tomography and sonography showed the suspicion of venous malformation with phleboliths. Superficial parotidectomy was performed. Pathological examination confirmed that the mass was venous malformation with phleboliths combined with sialolith in the parotid gland. We present the case of unilateral parotid swelling caused by a venous malformation combined with sialolithiasis.

We investigate the effect of government and public sector R&D Investment at IT Industry on the amount of Production, export and nongovernment R&D Investment at IT Industry. We, firstly, examine the stationarity of each variable by the unit root t-test and perform the co-integration test for the pairs of variables. We use YECM(Vector Error Correction Model) according to the results of co-integration test for the examination of Granger-causality between variables. It is found that there exist an Granger-causality between public sector R&D Investment and nongovernment R&D investment and also between public sector R&D Investment and export. Secondly, we analyze the impulse response of government and public sector R&D Investment at IT Industry on the amount of production, export and nongovernment R&D investment at IT Industry based on VECM model. It is found that the response of the amount of production is highest at 3th period and is lowest at 8th period and that of export shows similar pattern.

This study was performed to analyze 48 kinds of pesticide residues using gas chromatography (GC)/nitrogen phosphorous detector, GC/micro electron capture detector, GC/mass selective detector, and high performance liquid chromatograph/diode array detector in 186 fresh ginseng samples collected in the Seoul area from 2010 to 2011. Fresh ginseng dietary intakes were estimated using the data from the 2009 Korea National Health and Nutrition examination survey. Residual pesticides were detected in 79 samples (42.5%) with eight different fungicides. Only 20 samples (10.8%) exceeded the maximum residue limits (MRLs) for pesticides registered by the Korea Food & Drug Administration. Among them, tolclofos-methyl residues (10.2%) exceeded the MRL for fresh ginseng in 18 ginseng seedlings and one of the two-year old fresh ginseng plants, and the residual level in just one ginseng seedling violated the MRL for pyrimethanil. The results showed that residual pesticides levels in marketable fresh ginseng around Seoul were relatively safe. The percent acceptable daily intake (%ADI) was calculated using pesticide residues in fresh ginseng and dietary intakes of fresh ginseng. The risk caused by pesticide residues in fresh ginseng was very low.

With the recent rise of apartment houses, the Korean government set up the Apartment House Manager System in 1989. In fact. a similar was originally introduced and fully settled down in England where the apartment house have been developed for a while. This study is primarily concerned with the comparison of apartment house manager system between Korea and England, with special respect to the background, the department in charge, the qualification of examinees, and the subjects for examination. The first part of this study deals with the difference of system between Korea and England. Among the most salient difference is that the system of Korea was established by the gorvernment itself in order to solve some problems derived from management, whereas that in England came into being for citizens to help the poor with housing problems as a Chrisitian social movement. The second part of this study suggests that it is necessary to open a department of apartment house at the two-year colleges. In addition, it would be advisable to give some advantages such as full a partial exception from examination to those who graduate from four-year universities or colleges.

방송사업자 인허가정책은 향후 추진할 방송산업의 구도와 성패를 좌우하는 중요한 정책결정으로서 방송정책에서 차지하는 비중과 의미가 매우 큰 분야이다. 뿐만 아니라 사업자 선정과정에서 빈번히 제기되는 투명성과 공정성 시비의 구조적 원인을 밝히는 차원에서도 이에 대한 체계적 연구는 시급하다. 이 논문은 1990 년 이후 선정한 방송사업자 인허가정책들을 대상으로 10여년간의 추세와 거기서 나타난 문제점들을 평가하고 대안을 제시하였다. 민영방송사업자(1990.10), 케이블 TV PP사업자(1993.8), 케이블 TV SO 사업자(1994.1), 지역민방사업자(1994.8), 위성방송사업자(2000.12), 신규홈쇼핑방송채널사용사업자(2001.3) 등 6 개 방송사업자 선정에 대해 심사기준과 심사과정을 중심으로 분석한 결과 지난 10여년간 방송사업자 인허가정책은 심사과정의 전문성과 다원성 그리고 심사기준의 세분화 등이 이루어져 인허가 심사의 투명성이 확보됨으로서 과거의 '밀실형 허가'가 '햇빛형 허가'로 발전되었다고 평가할 수 있다. 그러나 심사기준의 세분화에 따른 배점의 계랑화는 상대적으로 미흡하여 심사의 공정성 확보 측면에서는 아직도 개선되어야 할 점이 많은 것으로 나타났다.

This study aimed to introduce what Korea national oral health surveys are and examine recent oral health status in Korean children. Korea Government has implemented national oral health-related surveys during the past two decades. The surveys with oral health examination are Korean Children's National Oral Health Survey (KCNOHS) since 2000 in 5-year-old and 12-year-old children and Korea National Hhealth and Nutrition Examination Survey (KNHANES) since 2007 aged 1 year and more. KCNOHS provides the information about the distribution of prevalence of dental caries, gingival health, behavioral factors, and dental clinic demands etc. KNHANES has huge amount of health data for representative Korean population including oral health and general conditions. Based on KCNOHS, the prevalence of dental caries and its experience has decreased steadily, and the status of oral hygiene and preventive treatment called sealents has been also improved after the year of 2000. However, there is still a gap to reach to those of Western developed countries. Therefore, more effective oral health policy plans and strategies for Korean children and adolescents are needed to prevent and manage for dental caries in private and clinical field of dentistry with public sector.
