Adenoid cystic carcinoma(ACC) is the second most common malignant neoplasm in the salivary gland. In spite of ACC shows slowly growing nature, it is sometimes highly detrimental that it readily invades adjacent tissues and metastasize to distant organs at the early stage of disease. Hence, treatment outcome may be misfortunate due to wide regional infiltration, pathognomonic perineural spread and the tendency of hematogenous metastasis. We present a unusal case of ACC of the scalp in which the patient initially presented with bumpy mass of the scalp who had been diagnosed as the primarily developed ACC of the right hard palate that extended to infratemporal fossa, nasal cavity, and paranasal sinuses and had been treated by total excision and post-operative chemotherapy and radiation therapy for 10 years ago. Although this lesion occured at the scalp, which is a frequent site of primary dermatologic ACC, its histomorphology was the same with that of previous tumor. Complete clinical examination showed no recurrence sign at the primary site and suggested the scalp as a sole treatment failure site. Accordingly, it would be reasonable to consider the present case as either a scalp metastasis or a second primary lesion of salivary gland ACC.

Objectives The relationships between adolescent depression and obesity, life style has been reported, but usually study results were not consistent with the study before. This study was designed to evaluate clear relationship between obesity and depressive trends, life styles in middle school students. Methods The study participants were the 1th, 2th grade students from one middle school in Kang dong Gu, Seoul(479 Students). The participants were measured their height and weight, and they were also surveyed by questionnaire. We diagnosed the students as depressives when they scored 10 points or above on Children's Depression Inventory(CDI) of Kovacs and Beck. Results The mean depression score in the obese group was significantly higher than that of the normal body weight group, and the more severely obese the group was, the higher the depression scores for this group were. The depression score of the boys obese group was higher than the girls obese group. The depression score was significantly higher in the obese group of people who hate to do exercising, like computer games and like watching TV instead, than in the group of people who like to do exercising and don't play computer games. Conclusions This study showed that depressive mood during adolescent was related to obesity and obesity-related lifestyles.

The Measurements of Data Accuracy and Error Detection in DEM using GRASS and Arc/Info

조성민,Cho, Sung-Min The Korean Association of Geographic Information S 1998 한국지리정보학회지 Vol.1 No.1

GIS 데이타의 정확도 문제는 DEM과 같은 데이터의 유용성과 적용에 대한 서로 다른 견해를 불러 일으킨다. 데이터의 정확성은 좌표의 정확한 위치와 속성정보를 무작위적으로 검색하여 결정할 수 있다. DEM은 과거 보다는 손쉽게 취득할수 있고 이를 처리할수 있는 소프트웨어도 다양해 졌으나 GIS의 응용은 이미 만들어진 데이터에 따라 그 결과가 달라질수 있으므로 데이터의 정확도와 에러에 대한 주의를 기울일 필요가 있다. 본 연구의 목적은 1:24,000과 1:250,000 DEM 데이터를 이용하여 DEM의 정확도를 검색하고 데이터가 지닌 에러를 찾아내는 방법을 모색하는데 있다. GRASS와 Arc/Info를 이용하여 DEM을 레이어로 만들어내는 과정 또한 연구 되었다. 연구지역은 250 $km^2$의 면적을 지녔으며 연구 결과 1:250,000 DEM에서는 실제 등고값이 정상적으로 처리 되었으나 1:24,000 DEM에서는 실제의 등고값이 아닌 0으로 표현된 에러가 발견되었다. The issue of data accuracy brings a different perspective to the issue of GIS modeling, calls into a question the usefulness of data models such as DEM. Accuracy can be determined by randomly checking positional and attribute accuracy within a GIS data layer. With the increasing availability of DEM and the software capable of processing them, it is worthwhile to call attention for data accuracy and error analysis as GIS application depends on the priori established spatial data. The purpose of this paper was to investigate methods for data accuracy measurement and error detection methodology with two types of DEM's: 1 to 24,000 and 1 to 250,000 DEM released by U.S. Geological Survey. Another emphasis was given to the development of methodology for processing DEM's to create Arc/Info and GRASS layers. Data accuracy analysis with DEM was applied to a 250 sq.km area and an error was detected at a scale of 1:24,000 DEM. There were two possible reasons for this error: gross errors and blunders.

This paper attempted to find implications for water resource management and water quality improvement by analyzing the causal relationship among discharge, water temperature and pollution index, which were expected to have a great effect on water quality with the rise of water temperature and precipitation change as the warming effect in recent years. For this purpose, the unit root test, cointegration test, and Granger causal test were carried out for 10 multi-purpose dams in Korean major water systems using time series data on discharge, water temperature, BOD, COD and DO. It was analyzed that the fluctuation of water temperature affected the pollution index more than the fluctuation of discharge volume. Also, Hapcheon dam and Chungju dam were the best water quality management dams based on the high causal relationship between water quality and discharge. The second rank was Daecheong dam. The third-ranking group were Yongdam and Andong dam, whose causal relationships between water quality and discharge were low. The last group were the remaining five dams.

조성민,김용탁,서용곤,윤형도,임영민,윤대호,Cho, Sung-Min,Kim, Yong-Tak,Seo, Yong-Gon,Yoon, Hyung-Do,Im, Young-Min,Yoon, Dae-Ho 한국세라믹학회 2002 한국세라믹학회지 Vol.39 No.5

저온($320^{\circ}$C)에서 $SiH_4$와 $N_2O$ 가스의 혼합을 통해 플라즈마화학기상증착(PECVD)법을 이용하여 실리카 광도파로의 클래딩막으로 사용되는 $SiO_2$ 후막을 제조하였으며, 공정변수로는 $N_2O/SiH_4$ 유량비와 RF power에 변화를 주었다. 증착된 시편은 $N_2$ 분위기의 열처리로에서 $1050{\circ}$에서 2시간동안 열처리하였다. $N_2O/SiH_4$ 유량비가 증가함에 따라 증착속도는 $9.4~2.9{\mu}m /h$까지 감소하였으며, RF power가 증가함에 따라 증착속도는 $4.7~6.9{\mu}m /h$까지 증가하였다. 두께 및 굴절률은 Prism Coupler를 이용하여 분석하였다. 화학적 성질 및 구조적 성질은 X-ray Photoelectron Spectroscopy(XPS)와 Fourier Transform-Infrared Spectroscopy(FT-IR)를 이용하여 분석하였으며, Scanning Electron Microscopy(SEM)를 이용하여 시편의 단면을 관찰하였다. Silicon dioxide thick film using silica optical waveguide cladding was fabricated by Plasma Enhanced Chemical Vapor Deposition(PECVD) method, at a low temperature ($320^{\circ}$C) and from $(SiH_4+N_2O)$ gas mixtures. The effects of deposition parameters on properties of $SiO_2$ thick films were investigated by variation of $N_2O/SiH_4$ flow ratio and RF power. After the deposition process, the samples were annealed in a furnace at $1150^{\circ}$C, in N2 atmosphere, for 2h. As the $N_2O/SiH_4$ flow ratio increased, deposition rate decreased from 9.4 to 2.9 ${\mu}m/h$. As the RF power increased, deposition rate increased from 4.7 to 6.9 ${\mu}m/h$. The thickness and the refractive index measurements were measured by prism coupler. X-ray Photoelectron Spectroscopy(XPS) and Fourier Transform-infrared Spectroscopy(FT-IR) were used to determine the chemical states. The cross-section of films was observed by Scanning Electron Microscopy(SEM).

의사를 위한 재무설계 사례연구

조성민(Sung Min Cho) 한국FP학회 2011 Financial Planning Review Vol.4 No.4

우리나라에 대략 18만 명의 의사가 존재한다. 그들은 10년 정도의 학업과정을 거쳐 히포크라테스 선서를 한 후 진정한 의사로 거듭난다. 의사가 된 후 그들은 어렵고 아픈 사람들을 위해 평생을 헌신한다. 그로 인해 상당한 경제적인 급부가 그들에게 주어진다. 사회적 통념상 의사는 부자로 인식되어지고 있으며, 그들에게는 다양하고 많은 정보가 주어진다. 하지만 정확한 프로세스에 입각한 재무설계를 통한 인생의 계획을 수립하고, 그것을 바탕으로 저축 및 투자 등의 체계적인 자산관리가 이루어지고 있는 의사는 그 수가 많지 않다. 본 연구는 전문직으로서 의사들의 재무적 니즈를 정확히 분석하여 재무설계와의 접목을 통해 그들의 현실적인 문제들을 해결해 나아가는 전 과정을 다루었다. 또한, 재무설계를 통하여 고객의 가치관과 인생관의 변화를 통해 재무설계의 효용성을 보여주었다. 의사를 대상으로 한 재무설계 프로세스는 병과와 나이에 따라 상이한 부분이 있지만, 본 사례는 다양한 병과별 연령별 의사들을 상담해본 결과를 바탕으로 일반적인 표준사례라 할 수 있겠다. 이를 통해 고객인 의사의 입장에서 상품세일즈 방식의 지엽적인 재무설계의 틀을 벗어나 종합적이고 포괄적인 재무설계의 진정한 가치를 발견하게 함으로, 재무적 목표와 비재무적 목표의 효용을 창출하며, 파이낸셜플래너와의 올바른 관계정립을 통하여 같은 전문가로서 위상을 정립하고 재무설계 프로세스의 방향성을 잡는데 도움이 되는 사례라 사료된다. There are about 180,000 medical doctors in Korea. In general, medical doctors are considered to belong to the highest income group and may have access to high quality information about various topics.
