강성구 강원대학교 대학원 2008 국내석사

배경과 목적 암은 조기에 발견하고 치료를 하면 완치를 기대할 수 있으나 진단이 늦어져 전이병변이 생길 때는 생존율이 현저히 감소한다. 따라서 암의 조기발견을 위해 임상에서는 많은 검사들이 이루어지고 있으며, 많은 연구들이 진행되고 있다. 다양한 암들 중에서 위암은 우리나라에서 유병률 1위, 사망률 2위를 보이는 가장 흔한 암이다. 위암의 진단을 위해 기본적인 검사가 이루어지고 있으며 최근에는 이러한 노력으로 조기에 진단되는 비율이 높아지고 있다. 최근의 연구결과들 중에는, 위암환자에서 함께 발견되는 질환 중에 대장신생물의 발생이 정상인에 비해 증가되어 있다는 보고가 있다. 본 연구에서는 위암으로 진단되고 수술 한 환자들을 대상으로 하여 대장내시경 검사가 시행된 환자들에게서 대장병변의 발생빈도와 특성에 대해 살펴보고자 하였다. 대상 및 방법 2000년 9월부터 2007년 10월까지 본원에서 위암으로 진단을 받고 수술을 시행 받은 230명의 환자들 중에서, 위암 수술 전이나 후에 대장내시경 검사를 받은 병력이 있는 64명의 환자들을 대상으로 하여 대장신생물의 발생양상과 병리조직학적 특징을 병록기록지를 참조하여 후향적으로 조사하였다. 결과 대상 환자들의 평균 연령은 63세(range:34-87세)였으며 남자와 여자의 성비는 2.6:1이었다. 전체 64명의 환자 중에 32명(50%)에서 병변을 관찰할 수 있었다. 용종이 22명(34.4%), 괴양성 대장염 2명(3.1%), 크론씨병 1명(1.5%), 대장암 7명(10.9%) 이었다. 22명의 용종환자의 병리조직학적 형태분류로는 증식성 용종 1명(4.5%), 증식성-선종성 용종 3명(13.6%), 관상 선종 14명(63.6%), 관상-융모성 선종 4명(18.2%) 이었으며, 선암으로는 그 위치에 따라 구분하여 보면 직장암이 3명, 구불결장암이 1명, 하행결장암 1명, 상행결장암 2명 이었다. 환자의 연령은 60세를 기준으로 그 이상인 경우는 44명이었으며 60세 미만은 20명이었다. 대장신생물은 60세 이상에서 24명(52.3%), 60세 미만에서 8명(40%)였으며, 선암은 각각 4명(9.1%)과 3명(15%)였다. 결론 본 연구에서는 위암환자들에게서 대장신생물의 발견율이 높다는 것을 확인할 수 있었다. 따라서 위암환자로 진단된 경우 수술하기 전에 대장내시경 검사나 최근 그 유용성이 증가되고 있는 컴퓨터단층촬영 대장조영술을 시행하는 것이 좋겠고, 수술 후에도 직장대장에 대한 적극적인 검사를 통해 대장병변을 조기에 발견하고자 하여야 할 것으로 보인다. Background and Objectives If a cancer is detected and treated early, we can expect complete recovery, but if diagnosis is delayed and there happen metastatic lesions, the survival rate decreases considerably. Accordingly, many researches are being made and reported on various tests used clinically for the early detection of cancers. Among many types of carcinoma, stomach cancer is most common, showing the highest prevalence in Korea. Several tests are performed before operation in order to measure the progress and to decide the operation method, and postoperative follow?up tests are also conducted to see the recurrence or metastasis of the disease. Some of recent researches reported that, among multiple cancers in stomach cancer patients, colon neoplasia showed an increasing frequency compared to normal people. The present study purposed to examine the frequency and characteristics of colon neoplasia in patients who had been diagnosed with stomach cancer, received surgical treatment, and had colonoscopic examination. Subjects and Methods The subjects were 64 patients who had colonoscopic examination before or after the operation selected from 230 patients who had been diagnosed with stomach cancer and received operation in the present hospital during the period from September 2000 to October 2007. For the subjects, we investigated retrospectively the pattern of the occurrence of colon neoplasia and the histopathological characteristics. Results The mean age of the subjects was 63 (34~87), and the ratio of males to females was 2.6:1. Of the 64 patients, lesions were observed in 32 (50%), of which 22 (34.4%) were polyp, 2 (3.1%) were ulcerative colitis, 1 (.15%) was Crohn’s disease, and 7 (10.9%) were colon cancer. The 22 polyp patients were classified histopathologically into hyperplastic polyp (1, 4.5%), mixed hyperplastic and adenomatous polyp (3, 13.6%), tubular adenoma (14, 63.6%) and tubulovillous adenoma (4, 18.2%), and the cases of adenocarcinoma were classified by position into rectal cancer (3), S?shaped colon cancer (1), descending colon cancer (1) and ascending colon cancer (2). As to age, 44 of the subjects were 60 or older, and 20 were younger than 60. Colon neoplasia was observed in 24 (52.3%) among those aged over 60 and 8 (40%) among those younger than 60, and adenocarcinoma was observed in 4 (9.1%) and 3 (15%) respectively. Conclusions Because of the possibility of multiple cancers, doctors who treat cancer patients conduct systemic examination for a patient who visited the hospital for the first time in order to find other lesions in addition to tests for determining the causes that led the patient to the hospital. The present study confirmed that the incidence of colon neoplasia is high in stomach cancer patients. Accordingly, in case a patient is diagnosed with stomach cancer, it is safe to do colonoscopic examination or CT colonography, which is increasingly useful recently, before operation, and after the operation as well the large intestine should be examined actively for early detection of colon cancer.

1. Preface A study on Suh-po was begun in earnest from the notes on the Ku-woon-mong by Dr. Lee Ga-won April, 1955. Publishing notes on the Ku-woon-mong by Prof. Lee Myung-ku, July in 1955 and a study on Suh-po by me in 1959, a study on Suh-pa has been hastened from Korean Independence from Japan. The following are essays on Suh-po. Written in the order of the times; (1) Notes on Nam-jung-ki(南征記論攷) in 1963. (國語國文學 通卷 26號 丁奎福) (2) A study on Sa-shi-nam-jung-ki in 1966. (韓國 古典文學의 理論, 正音社, 全圭泰) (3) A study on the Ku-woon-mong's thought in 1967. (亞細亞硏究 No.4, 丁奎福) (4) A study on the Ku-woon-mong in 1968. (國文學硏究 第6輯, 金炳國) (5) A study on the Background of the Ku-woon-mong's Thought in 1970. (東亞出版社, 朴晟義) (6) Comparative Literary Study on the Ku-woon-mong in 1970. (高大論文 集16輯, 丁奎福) (7) Notes on the Ku-woon-mong in 1969. (韓國 小說硏究中에서 宣明文化社, 李在秀) The above mentioned essays have their own opinion But they are wanting in studying Suh Po extensively. Throughoughout a criticism on the author Suh Po, his background, thought, and works, some scholars treat throughly a sphere. Though Sa-shi-nam-jung-ki and the wu-moon-mong are written by same author, they say the latter is superior to the former in value and criticism. Prof. Chung's study on Sa-shi-nam-jung-ki, comparative study on the Ku-woon-mong, a study on a root of narration, a study on different copies of Suh Po's works give the learned circles much attention. And the mental analytical study on the Ku-woon-mong by Kim-byung-kook is a fine idea More over his attempt of new methodology is also excellent merits. A study on the thought's background in the Ku-Woon-Mong by Prof. Park-sung-eu is not only a merit of him in seeking a sphere, but his Third Dogmatics of unity makes clear of his opinion. The analysis on the Ku-woon-mong by Dr. Lee-jae-su and Prof. Chun Kyu Jae is very elaborate and systematical. 2. Suh-Po's Life and Character I'm going to cast a look at dignity and family line of Suh Po Kim Man Jung, unforgettable being in the history of Korean literature. Kim Man Jung named. Jung Sook as his other name had the pen name of Suh-Po and Moon Hyo given by King Sook-jong while he had lived a checkered career for fifty six years since he was born in 1637, He who was born as a descendant of the Kwang-san-Kims had grand-grand father, Kim Chang-saeng named the pen-name of Sa Gye, and father named Ik Gyum. His eldest brother, Sub-suk Man-kee, was father of queen In Gyung, and the governer Han Yu Ryang was his father-in-law. The premier Yoon Du Soo, the late premier Bang whose pen-name given by king was Moon-ik, at that time, was grand father of his mother. Sin Ghee, king's son-in-law was father of his mother, and the princess Chung Hye who was daughter of King Suok-jong was mother of his mother. His maternal grandfather named Chee was home minister at that time, but his father Ik Gyum died for king while he was staying in Kang Hwa Island, where is his home. At that time Suh Po, Kim-man-jung, was in the period of maternity, and his elder brother, Man Kee, five years old. His mother always kept house for Mrs. Hong, who was her grand-mother, and she helped her father, who had no son, as if she had been son of her grand-parents' home. Her grand-father failed to think of his son owing to his daughter's duty to him, and he often told not only was always glad whenever he told with his grand-daughter, but he was a great-teacher of his home if she had been a son. As her grand-father was always proud of her, Man-jung had a great mother, but he was always father in his mind while following his mother's stern teachings with his elder brother Man-kee. And of his eldest brother's five sons Chin Ku and Chin Kyu were high and distinguished officials at that ttime, and they received the most stipend, but Chin Ku was banished to Che Ju island, Chin Kyu to Keu Jae island, when Suh Po was exiled to Nam-Hae island owing to Kee Sa year's political change. In that state rather than he ate humble pie, Suh-pa made stubbornly other attempt with redoubled effarts while exiling in Nam Hae Island. Sub-pa sent a secret letter to Choon-tack, Chin Ku's Son in Seoul, to restore the Suh In Party's rights. After then Choon Tack was also banished to Che Ju Island on the suspicion of slaying King Kyung-jong. At any rate even though he was endowed a great descent, Suh-Po couldn't over come his flexible home state alone. Though he led an obscure life as a politican, he lived firmly, as a writer, than any other writer in oriental history. 3. Sa shi-nam-jung-ki & the Ku-woon-mong Suh Po wrote the two great works, Sa-shi-nan-jung-ki & the Ku Won Mong. But they have the different continents, in spite of the novels by same author. Putting in prison, Suh Po wrote Sa-shi-nam-jung-ki with eager attempt for the restoration of the Suh In Party To appreciate the theme of Sa-shi-nam-jung-ki properly, we should not place it under the category of general home fiction's theme. The theme of Home troubles in Nam-jung-ki can be found in many novels during Lee dynasty. It is often called exposing, satirical novel with moral purpose, for it was written to make King Sook-jong repent Sub Po's exiling. Therefore it is not the conflict of the previous wife, but a novel with deep purpose for nation, peoples, administrative power and family power. The Ku-woon-mong is not only the last accumulation of Suh-po's sweat and blood, but the theme of it is the mental task which keeps understanding and comment of him. Being sceptic in life, he was indulged in Confucious & Fairy thoughts. Those novels are perhaps a kind of reduced copy which examines Suh-po's vision. What on earth is the mental principle of Suh-po? It is real combination of his view of life & religion which led the second dimension world into the first dimension world. Suh-Po expected to be well up in both literary and military arts and to live happily, and then not only he denied woman's independence but he accepted the class-conciousness of conventional feudal-society and polygamy. Joy and sorrow of life being an empty dream, Suh Po's Ku-woon-mong is the only nihilistic thought which his view of life & religion is united into the first dimension world from the second dimension world 4. Conclusion Suh Po was born poor, learned confucious, and finally he failed in participating in the politic. As a writer he wrote 「Nam-jung-ki」 and 「the Ku-woon-mong」 Being sceptic in life, he was indulged in Confucious and Fairy thoughts. Those novels is a kind of reduced copy which examines Suh-po's thought. Throughout them we can find Suh-po's life, thought, and religion. Moreover it tells his fate. Though there are many novelists, there are few writers who wrote the different works by same author. One is 「Nan-Jung-Ki」, and the other 「the Ku-woon-mong」. The former is written to carry out his purpose, the latter is written to express nihilistic thoughts. Therefore Suh-po have always the differant essences in his works. Suh-po has. that is, always both-sided valuation throughout his life. And then all of his works and thoughts always keep both bright and seamy sides on life. At last he finished his life in the both sides. That is just the Suh-po's fate, art, and the end of his life.

Multimodal 광역권 교통수요 모델 구축에 관한 연구

강성구 공주대학교 대학원 2022 국내박사

The basic data used in the transportation SOC construction project through the establishment, implementation, and evaluation of domestic transportation plans are distributed by KTDB. Based on network, public transportation, and O/D, it is constructed and utilized by metropolitan area according to the analysis target area. However, for realistic transport demand analysis, the existing network, public transport, and aggregation models for each metropolitan area are insufficient. Therefore, it is necessary to establish a metropolitan transport demand model according to the transport system for each metropolitan area and the purpose of analysis. Based on the metropolitan area, which is the spatial scope of this study, a network model establishment methodology was presented by setting the necessary areas and combining networks using the nationwide, metropolitan area, and GIS data networks. In order to reflect the selection of mode choice between public transportation and private transportation and the realistic transportation system, segmentation of transfer stops, classification of bus and rail routes, reflection of actual operation schedule, and integrated fare system were applied. Accordingly, a methodology that supplemented the reality such as the approach of the stop and the transfer system of the transfer stop was presented. The existing methodology applies the mode choice reflecting the aggregate model to the new SOC construction project. It is in the process of performing transport demand analysis through the settlement of the mode choice model. Such a traffic demand analysis process is insufficient to reflect the individual behavioral aspects of passers-by. In this study, a person group, trip purpose, and trip-chain were constructed and reflected in the model based on household travel status survey data. In addition, among the errors in calculating the amount of traffic generated in the traffic zone, the building information and land characteristic information by use provided by NSDI, which is the data of socioeconomic index items, were used. Therefore, a method that minimizes exogenous errors was used and presented. As a case study according to the establishment of a multimodal metropolitan area transport demand model, GTX-B, which is the most important issue in the current railway SOC, was analyzed. Demand for use between stations in the future and demand for getting on and off (by direction, time of day, transfer, and congestion rate analysis) were analyzed. Based on this, the required organization and operation plan for the future GTX-B route operation were presented. Therefore, it can be expected to improve the accuracy and reliability of forecasting traffic demand analysis through segmentation of information to reflect the transportation system of private and public transportation and building a multimodal transportation demand model that considers individual behavioral characteristics.

투과전자현미경을 이용한 MgB2 초전도 선재의 미세구조 분석

강성구 경상대학교 대학원 2009 국내석사

Enormous research efforts such as materials performance properties, improvement of conducting property, and demonstrations of magnetic origin have been going on in the MgB2 field since its discovery in 2001. For conductors, the powder-in-tube (PIT) method is very common, in which a metallic sheath is packed with powders and then is drown. The MgB2 fabricated by the PIT method is polycrystalline, and it is well known that there are no weak-link effect at the grain boundaries. To enhance critical current density (Jc), upper critical field (Hc2) and irreversibility field (Hirr), several techniques might be considered. In general, carbon-based chemical doping of MgB2, including SiC, B4C, CNTs have shown significant improvement of the Jc. Recently, the chemical doping for MgB2 was successfully extended to organic compound and has been paid much attention to further improve the superconducting properties. Especially, addition of hydrocarbon which has no oxygen content is very effective for increasing Jc under high magnetic fields. However, the mechanism of the significant Jc enhancement by the hydrocarbon doping is not fully understood because of the deficiency of detail microstructure analysis. In this study, therefore, TEM analysis was used to obtain the microstructures of MgB2+10 wt% C4H6O5 wires and MgB2+10 wt% C16H10 wires with different heat treatment conditions. Superconducting properties of carbon doped MgB2 wires and their correlation with the microstructures have been investigated in details. TEM and EDS analysis were conducted on the specimens prepared by tripod polishing and ion milling method. The microstructure of MgB2 wires has been investigated by transmission electron microscopy (TEM) equipped with energy- dispersive X-ray spectroscopy (EDS). MgB2 wires were fabricated through powder-in-tube (PIT) process using pure Fe as sheath material and sintered at various temperature conditions range from 600 ℃ to 1000 ℃ for 30min to 4hr. The structural features such as grain size distribution, connectivity, and lattice disorder were investigated by electron microscopy. It was found that microstructure had a strong effect on the Jc in magnetic fields. We also observed the microstructural variations with sintering temperature through the cross-sectional TEM analysis of MgB2 wires. carbon doping was effective in creating nano-sized carbon-containing inclusion in the MgB2 wire. In case of malic acid (C4H6O5) added samples, the size of carbon-containing inclusions increased with the sintering temperature together with the grain size of MgB2. The Jc value increased with sintering temperature up to 800 ℃ ~ 900 ℃ and decreased at higher sintering temperature due to the formation of 10-20 nm amorphous MgO layer covering MgB2 grains. In case of pyrene (C16H10) added samples, two kinds of sample which we considered showed evident difference of microstructure. In SEM results, structural granularity seems an important factor which can affect Jc property. According to TEM analysis, decrease of the MgB2 grain size, increase of the grain boundary area, and the carbon substitution, which were caused by the doping of pyrene, are responsible for the significant enhancement of Jc of MgB2 wires.

도시철도의 Ramp-up을 고려한 초기 교통수요 안정화 분석

강성구 공주대학교 대학원 2018 국내석사

Ramp-up은 신규 교통시설 및 시설의 개량 이후 초기 교통수요가 등락을 반복하며 큰 폭으로 상승하다 점차 안정화되는 현상으로 현재 교통수요분석에서는 Ramp-up이 사실상 고려되지 못하였으며, 그 결과 초기 교통수요의 특성이 제대로 규명되지 못하여 교통수요분석의 신뢰도가 저해되므로 Ramp-up 효과의 체계적인 반영이 필요한 실정이다. 이에 본 연구에서는 개발된 방법론을 적용하며, 기존의 대형 국책 SOC사업 및 도로환경 변화에 따른 개통초기 교통수요만을 반영한 방법이 아닌 Ramp-up효과를 적용하고 추가적으로 도시철도역에 접근 가능한 행정구역별 인구의 변동에 따른 표준화수요를 산정하여 Ramp-up 효과의 적용되는 지표를 제시함으로써 초기 교통수요의 과다/소 추정되는 오류의 보완 및 Ramp-up 효과 적용 방안을 마련하여 개통 초기교통수요분석의 신뢰성 향상을 기여하고자 한다. Ramp-up 방법론은 기존 연구의 임의적 판단을 최소화하며, 통계적으로 유의한 Ramp-up 파라미터를 산정하기 위해 F-검정을 통해 Ram-up을 찾는 분석방법론을 적용하였다. F-검정 시 수요는 월별 실적자료를 활용하며, 월별 실적자료 이용 시 기본적인 월변동이 발생되므로 월변동계수를 적용하여 누적수송 실적에 반영하도록 한다. 철도 노선의 월별 누적수송 실적에 대한 자료 확인 결과, 노선 신설 시 직접적인 영향력이 있는 주변영향권 노선의 수요 변동이 미세하며, 광역버스 노선의 신설 및 여러 가지 외생변수 등을 반영하기에 데이터 수집에 한계가 있으므로, 본 연구에서는 도시철도역에 접근 가능한 행정구역에 대한 인구수 산정을 위해 행정안전부에서 제공되는 연간 및 월간 주민등록 인구자료를 활용하여 연평균 및 월평균 증감률을 산정하여, 본 연구의 F-검정 시 지표가 되는 표준화수요를 산정하였다. 서울시, 서울시↔경기도 유·출입 통행, 경기도 3개의 권역을 구분하여 각 권역별로 최근 10년 이내 개통되어 기 운행 중인 노선(서울9호선, 경의선, 신분당선, 분당선, 중앙선)에 대하여 Ramp-up 효과를 분석하였다. 개통 후부터 Ramp-up 단계의 표본을 분자, 안정화 단계의 표본을 분모로 설정하여 F비를 산정한 후 F비가 F-기각치 보다 작을 경우 가설을 채택하여 안정화단계로 F비가 F-기각치 보다 클 경우 Ramp-up이 계속 진행된다는 가정을 설정하였다. 권역별 Ramp-up 기간 및 Ramp-up 지수를 분석하였으며, 장래 신설될 노선 및 개통 직후 노선에 적용될 수 있도록 권역별 Ramp-up 기간 및 지수를 평균화하여 지표를 산출하였다. 권역별 Ramp-up 분석결과를 바탕으로 Ramp-up 기간 및 비율 추정결과, 서울시 23개월(67.6%), 서울시↔경기도 23개월(68.3%), 경기도 22개월(74.4%)로 평균지표를 산정하였다. 본 연구에서는 기존 대형 국책 SOC 사업 및 도로환경 변화에 따른 개통초기 교통수요의 신뢰성을 향상하여 초기교통수요의 과대/과소 추정으로 발생되는 국비를 확보하여 SOC 사업의 확대 및 균형발전에 기여할 것으로 기대된다. Ramp-up is the fluctuation of the initial traffic demand after an improvement in traffic facility or service occurs. These traffic demand will gradually stabilize when travelers become familiarized with the new travel opportunity. As a result, ramp-up is not being considered in the actual traffic demand analysis. Hence, the reliability of traffic demand analysis is hindered because it is essential to consider the key parameters of Ramp-up. This study applied the existing developed methodology in the calculation of traffic demand for the existing large-scale national SOC project and also reflected the Ramp-up effect based on the initial traffic demand for each road environment. In addition, so as to improve the reliability of the initial traffic demand analysis, a Ramp-up effect index was designed by supplementing the over-/under-estimated error of the initial traffic demand. The index parameters are designed according to population and the accessibility to urban railway stations. The Ramp-up methodology minimizes arbitrary judgments from existing studies and applies an analytical methodology through F-test to calculate statistically significant ramp-up parameters. The F-test utilizes monthly performance data, and the monthly variation coefficient is applied to the cumulative transport performance, since the monthly data use generates basic monthly variation. As a result of data verification on the cumulative transport performance of railroads and routes, the change in demand of nearby subway routes with direct influence during the establishment of new routes is small, reflecting the construction of local area bus routes and other external parameters. Consequently, in order to estimate the population of administrative districts which are accessible to urban railway stations, this study uses the annual and monthly resident population growth rate provided by the Ministry of Public Administration and Security. The standardization demand was estimated based on the indicators of the F-test. The Ramp-up effect of urban railway lines in Seoul and Gyeonggi Province (e.g. Seoul Line 9, Gyeonggi Line, Shinbundang Line, Bundang Line, and Chungang Line) which have been in operation within the last 10 years was analyzed in this study. For the computation of the F ratio, the sample data from the initial operation of the line up to the ramp-up phase was set as the numerator, whereas the data on the stabilization phase as the denominator. If F ratio is less than the F-rejection value, the hypothesis is accepted therefore the stabilization phase had occurred. However, if the F ratio is larger than the F-rejection value, it is assumed that the ramp-up phase continues. The Ramp-up period and index parameters for each region were analyzed. The indicators were calculated by averaging the Ramp-up period and index for each region in order to be applied in the design of a new urban railway lines. Based on results of the Ramp-up analysis by region, the average index was calculated as 23 months(67.6%) in Seoul, 23 months(68.3%) in Seoul and Gyeonggi province, 22 months(74.4%) in Gyeonggi.
