Tracheobronchopathia osteochondroplastica (TPO) is a rare benign disease of unknown etiology characterized by multiple cartilaginous or bony submucosal nodules, which project into the tracheobronchial lumen. Although some disorders were reported combined with TPO, these seemed to be considered casual. We report a case of TPO that combined with adenocarcinoma of lung. She was 50-year-old non smoking woman presented with chronic cough with right chest pain. Lung mass on right lower lobe was found on chest x-ray, so lung cancer was suspected. Multiple scattered whitish small elevations from trachea to bronchial trees were found on bronchoscopic exam. We mistook these lesions for metastases from lung cancer and biopsies of these lesions were done. Transbronchial biopsy for right lower lobe mass lesion was also done. But biopsies from trachea and bronchus revealed TPO rather than lung cancer. Transbronchial lung biopsy of right lower lobe mass was diagnosed adenocarcinoma of lung. So TPO combined with adenocarcinoma of lung was diagnosed.

This study was performed to investigate the effect of Chungkuk Jang added-diets on reducing cadmium toxiclt in rats (Sprague-Dalvley, ♂, 125 58±4.04g) used as experimental groups. There are six experimental groups, a normal group(Tn), a cadmium treatment group(control group Tc), four cadmium and Chungkuk Jang (0.25%, 0 50%, 1 00%, and 1 50%; T_1 T_2, T_3, and T_4) treatment groups which received different dietary feeding for 8 weeks each The results are as follows. 1 The amount of food intake at Chungkuk Jang mixed group(T_1, -T_2) was 3 5% greater than at the Tc group For the group fed Chungkuk Jang the average of weight gain was 4.42g/day, which showed higher value(2.79%) than the Tc(4 30g/day) group. The food efficency rate of intake Chungkuk Jang group (5.02) was a little higher without significance than that of the Tn(4 91) and Tc(4 99) groups. 2. The amount of water intake was the highest in the Tn(32.44?/day) group and 30.14% greater than that of the Tc(21.66?/day) group. For the water intake (T_3) among Chungkuk Jang added-diet groups showed the highest value(22.78?/day) relatively Cadmium intake of each group was in the range of 1.94 to 2.27 ppm and the T_3 group showed the highest cadmium intake. For the growth rate the Tc group was 7.62% lower than Tn group but the Chungkuk jang fed group resulted in a reduced fashion-about 3% in the growth process against the Tn group 3 There was no significant weight gain or loss of the organ and bone of rats among the experimental groups but in the case of liver and kidney the T_3 (8.59%. 12 36%) was higher than the Tc group 4 Cadmium accumulation was high to low in order of liver > kidney > spleen > heart > lung > testicle > brain > femoral muscle > femur >(T_1, T_2, T_3, and T_4). tibia > blood. The 70% accumulation rate was showed in liver (33 2%), kidney (31.25) and spleen (6 1%). The contents of cadmium in tissue and body-hair in the Chungkuk Jang intake groups(T_1, T_2, T_3, and T_4) were lower than in the Tc group. The chungkuk Jang added-diet groups (T_3, and T_4) showed low levels of cadmium accumulation

웹과 DB상의 효율적인 정보검색을 위한 데이터 통합 시스템 설계

주경희,김홍식,서재현 인제대학교 기초과학연구소 2000 자연과학 Vol.4 No.-

현재 인터넷상의 많은 정보자원들은 시스템 및 데이터 모델, 질의어, 스키마 등 여러 단계에 있어 이질성을 가지고 있으며, 데이터베이스분야에 있어서도 이질적인 데이터베이스의 통합은 중요한 문제가 되어왔다. 또한 사용자들은 현재 데이터베이스에 저장된 정보뿐만 아니라 웹 상에 산재한 정보들에 대해 하나하나 직접 접근해야 하는데, 사용자들은 단일화된 뷰를 통해 웹과 데이터베이스 정보들을 손쉽게 검색하길 원하며, 이질적인 데이터들의 통합을 필요로 하는 애플리케이션도 증가하고 있다. 이러한 애플리케이션을 만드는데 드는 많은 비용과 노력을 줄이기 위해, 웹과 DB상의 데이터를 단일화된 뷰를 통해 제공하는 데이터통합시스템이 요구되는데, 본 논문에서는 mediator-wrapper구조를 이용해, Web상의 자원들과 이종의 데이터베이스자원들을 통합된 뷰를 통해 제공하는 데이터통합시스템구조를 제안하고자 한다. Currently, lots of internet information sources have heterogeneity in the various level, such as in system, data model, query language and schema etc., and heterogeneous database integration has been the important issue in database area. And besides, users have to access directly to the data in database as well as to the data on the Web, but they want to easily retrieve the information of the Web and DB through a integrated view. And applications to require the integration of heterogeneous data increase continuously. To save much expense and effort in making these application, a data integration system to expose data on the web and in database through a integrated view is required. So, in this paper, 1 suggest data integration system structure to expose data on the web and in database through a integrated view using mediator-wrapper structure.

Wrapper 자동생성 에이전트를 이용한 XML 기반 데이터 통합 시스템 연구

주경희,김흥식,서재현 인제대학교 2001 仁濟論叢 Vol.16 No.1

인터넷 사용이 급격히 증가하면서, 인터넷상에 분산된 이질 정보자원들에 대해 사용자가 쉽게 접근하도록 하기 위해 몇몇 통합시스템들이 제안되고 있는데, 이들 통합시스템은 대개 mediator-wrapper 구조를 가지고 있으며, 이는 분산 이질 정보자원들 각각에 대해 wrapper를 필요로 한다. 하지만 개발자들이 일일이 wrapper를 직접 작성하는 것은 많은 시간과 비용을 요구하며 지금도 증가하고 있는 정보자원들을 고려해 보면 매우 비실용적이다. 그러므로 본 논문에서는 wrapper 작성시 소스에 한정되는 상세한 부분은 wrapper 개발자와 상호작용을 통해 작성되게 하고, 공통적으로 해당하는 부분은 명세를 통해 자동으로 생성되게 하는 wrapper 생성 에이전트를 이용한 XML 기반 데이터 통합 시스템을 제안한다. As internet usage rapidly increases, several integration systems have been proposed to make users' access easy and these usually have mediator-wrapper structure which needs a wrapper for each distributed heterogeneous information source. However, developers' hand-writing for each source requires much time and expense and, considering the increasing number of web information sources, it is rather impractical. Therefore, in this paper, I suggest an XML-based data integration system that makes source-specific details written through interaction with wrapper developers and common parts automatically written through specification using a wrapper generation agent.

The desire for the healthy life is increasing as a result of rapidly changing social and economic environment in Korea. Because of the need, information on health, food and nutrition are being introduced through the mass media. The object of this study is to investigate and analyze the quantity and quality of information about health, food and nutrition in women's magazines. Six representative domestic monthly magazines(Lady Kyunghyang, Women Donga, Women Chosun, Women JoongAng, Women sense, Jubu Senghwal) were selected for this study. The results of monitoring from June 2002 to September 2002 for the women's magazines were summarized as follows; 1. The percentage of the articles on health, food and nutrition by total area of the women's magazines was 23.1%. There were total 595 articles on health, food and nutrition. Among these, 400 articles(67.2%) were about food and nutrition. 2. The percentage of the advertisements on health, food and nutrition was 35.3% by total area of the woman's magazines. There were 2,353 advertisements on health, food and nutrition. Among these, 1,574(66.9%) advertisements were about food and nutrition. The most frequently advertised advertisements on food and nutrition were about processed foods (527 cases, 33.5%). The second most frequently advertised advertisements were about diet (374 cases, 23.8%). The third one was healthy foods (345 cases, 21.9%). 3. The contents of 215(53.8%) articles (the total number of articles was 400) was suitable. The contents of 89 advertisements(22.3%) did not have accurate information on health, food and nutrition. For the advertisements in women's magazines (the number of total articles was 2,203), the percentage of the advertisements which was not able to capture the feature of the advertisements was 27.9%, insufficiency of reliable sources was to 21.9%, and exaggeration of the contents in the advertisements was 16.0%. Articles and advertisements should be backed by scientific research or reliable sources and also the opinions of people with expertise in order to report accurate information to the general public. In order to achieve these results, there should be continuing monitoring activity for the women's magazines.

The author present a modified multi-loop algorithm including feedforward for controlling a 55kW step down chopper in the power supply of Maglev. The control law for the duty cycle consists of three terms. The first is the feedforward term which compensates for variations in the input voltage. The second term consists of the difference between the slowly moving inductor current and output current. The third term consists of proportional and integral terms involving the perturbation in the output voltage. This perturvation is derived by subtracting the desired output voltage from the actual output voltage. The proportional and integral action stabilizes the system and minimizes output voltage error. In order to verify the validity of the proposed multi-loop controller, simulation study was tried using Matlab simulink.

본 연구는 비인두와 adenoid의 성장발육 양상을 조사하여 부정교합자의 진단에 있어 비호흡 기능 평가시 유용한 기준을 얻기 위하여 시행되었다. 남자 19명, 여자 14명, 총 33명의 정상 교합자를 대상으로 8.5세부터 18.5세까지 촬영된 10년간의 누년적 측모 두부 X선 규격사진을 연구 자료로 비인두와 adenoid 부위의 거리와 면적 및 상대적 기도 비율을 계측 분석하여 다음과 같은 결론을 얻었다. 1. 각 연령(8.5세-18.5세)에서 남녀별 각 계측항목의 평균과 표준 편차를 얻었다. 2. 비인두의 height와 depth는 남자에서 14.5세까지, 여자에서 12.5세까지 성장하였다(p<0.05). 3. 비기도의 상대적 면적은 8.5세에 최소치를 나타내었고 남자는 10.5세부터 12.5세 사이에, 여자는 12.5세부터 14.5세 사이에 유의한 증가를 나타내었다(p<0.05). 4. 비기도의 상대적 면적과 비기도 관련 계측항목 간의 상관분석에서 Ad2-PNS, Ad2-PNS/Ho'-PNS 및 Upper pharynx가 남녀 모두 전 연령구간에서 비기도의 상대적 면적과 상관성이 있었다(p<0.01). The purpose of this study was to evaluate the growth pattern of nasopharyx and adenoid and to obtain useful measurements for evaluating the fuction of the nasal breathing. The biennial serial cephalometric radiographs of 33 samples(19 male, 14 female) with normal occlusion from 8.5 years to 18.5 years of age were used in this study. The distances, areas and ratios on nasopharynx and adenoid were measured and analyzed in each age and sex. The results of this study might be summarized as follows; 1. The mean value and standard deviation of each measurement was obtained in each age and sex. 2. The nasopharyngeal height and the nasopharyngeal depth increased significantly by 14.5 years of age in male and 12.5 years of age in female(p<0.05). 3. The relative nasal airway area showed the minimal value at 8.5 years of age and showed significant increase from 10.5 years to 12.5 years of age in male and from 12.5 years to 14.5 years of age in female(p<0.05). 4. In the correlation analysis between the measurements on the nasal airway and the measurement of relative nasal airway area, the measurements of Ad2-PNS, Ad2-PNS/Ho'-PNS and Upper pharynx appeared significant correlation with the measurement of relative nasal airway area(p<0.01).
