목적: 복부압박장치를 적용한 정위적방사선치료 시 환자 호흡에 기인하는 내부종양용적의 동적변이 양상을 연구하고자 하였다. 대상 및 방법: 2012년 4월부터 2013년 4월까지 복부압박장치를 이용하여 정위적방사선치료를 받은 폐암 환자 20명(상엽 7명, 중엽 4명, 하엽 9명), 총 67건을 대상으로 하였다. 치료 자세의 변동과 호흡에 의해 움직이는 종양 위치 변동을 알아보기 위해 4차원 cone- beam CT (4D-CBCT)를 사용하여 좌표 이동 값을 얻었다. 각 부위별로 LR (좌우), SI (상하), AP (전후) 방향의 벡터의 95% 신뢰구간(95% Confidence interval, 95% CI), 최대값, 그리고 최소값을 통하여 비교하였으며 자세변동 보정 값과 호흡변동 보정 값 간의 피어슨 곱 상관계수를 통하여 일치도를 분석하였다. 결과: 호흡에 의한 종양용적의 각 부위별로 변동은 폐 상엽에서 1.8~2.9 mm, 중엽과 하엽에서 2.3~5.4 mm, 2.2~4.0 mm로 분석되었다(95%CI, P<0.001). 자세변동 보정 값과 호흡변동 보정 값 간의 일치도($R^2$)를 살펴보면 상엽은 LR방향, SI방향, AP 방향에서 각각 0.75, 0.68, 0.63으로 나타났고, 중엽은 각각 0.82, 0.51, 0.92로 나타났으며, 하엽은 각각 0.63, 0.50, 0.34로 나타났다. 결론: 폐암의 정위적방사선 치료 시 복부압박장치의 사용으로 폐에 위치하는 종양은 환자 호흡에 의해 각 부위별로 각기 다른 양상을 보였다. 따라서 치료 자세에 대한 보정뿐만 아니라 호흡에 의한 변동을 보정해야만 한다. 또한 이러한 각기 다른 동적변이로 인한 오차의 보정 시 4D-CBCT의 사용은 매우 유용한 것으로 사료된다. Purpose: Abdominal compressor is used to control breathing in stereotactic body radiotherapy for lung tumors frequently. We evaluated the dynamic variation aspect of internal tumor volume by breathing. Materials and Methods: We reviewed 20 lung cancer patients (7 upper lung patients, 4 middle lung patients, 9 lower lung patients) who received stereotactic body radiotherapy using abdominal compressor between April 2012 to April 2013. Coordinate shift values were obtained by using four-dimensional cone-beam CT (4D-CBCT) to investigate treatment set-up error and moving tumor position error. To investigate how much difference of each part, we compared 95% confidence interval, maximum values and minimum values of three-dimensional vector value and analyzed conformity degree through the Pearson square correlation coefficient. Results: 95% confidence interval of three-dimensional vector value of each part is 1.8~2.9 mm in upper lobe, 2.3~5.4 mm in middle lobe and 2.2~4.0 mm in lower lobe. Conformity degree was the result that respectively is LR direction 0.75, SI direction 0.68 and AP direction 0.63 in upper lobe, LR direction 0.82, SI direction 0.51 and AP direction 0.92 in middle lobe and LR direction 0.63, SI direction 0.50 and AP direction 0.34 in lower lobe. Conclusion: We showed difference by each site in lung tumor due to respiration by using abdominal compressor. Therefore, we must correct treatment set-up error as well as moving tumor position error by breathing. It is also considered to be useful that it is the use of 4D-CBCT when correcting the error due to various dynamic variation.

포털미디어 뉴스의 재편집에 관한 연구

박광순(Kwang Soon Park) 사이버커뮤니케이션학회 2008 사이버 커뮤니케이션 학보 Vol.25 No.1

포털사이트에서 언론사닷컴 뉴스는 본문을 제외한 모든 편집요소들이 다양한 방식으로 재편집되고 있었으며, 재편집되는 비율도 매우 높게 나타났다. 뉴스의 재편집은 언론사닷컴 뉴스에 배치된 시각적 요소를 삭제, 확대, 축소, 추가, 변경 등의 방식과 원문뉴스에 배치된 시각적 요소를 다른 공간에 재배치하는 방식으로 이루어고 있었다. 포털뉴스에 게재된 광고는 언론사닷컴 뉴스에 게재된 광고보다 많은 것으로 나타났으며, 광고의 배치공간에 고정되어 있었다. 따리서 포털뉴스에 배치되는 광고 공간에 이미 배치된 언론사닷컴들의 편집요소는 재배치될 수밖에 없다. 언론사닷컴 뉴스에서는 사진, 그래픽 이미지, 정보그래픽 등과 같은 시각적 효과가 큰 요소들을 뉴스본문 상층부에 집중 배치되고 있는 반면, 포털뉴스에서는 비교적 다양한 공간에 배치되고 있었다. 뉴스의 시각화는 언론사닷컴 뉴스에 비해 포털뉴스에서 그리고 네이버뉴스에 비해 다음뉴스에서 더 활성화 되고 있었다. In portal sites, the media companies' online news has been reedited into various forms. All of editable elements except the body of news have been also reediting in online portal news. The proportion that the media companies' online news is reedited has showed to be very high. The media companies' online news in the portal site has been reedited by means of two kinds of styles. One is the style that visual elements arranged in the media companies' online news are deleted, enlarged, reduced, supplemented and changed, and the other is the one that the visual elements in a body of news are reedited in any other space of article. In media outlets' online news, those visual elements that have great effectiveness like pictures, graphic images and informative graphics tended to be arranged intensively in the upper part of the news body. But these elements in news of the portal sites tended to be arranged in the relatively diverse spaces. The visualization has been more active in news of portal site than the media companies' online news Also, in the portal sites, it was more active in news of Daum than Naver.

허튼(Hutton)의 PR모델을 이용한 지적재조사 홍보 방법

박광순(Park, Kwang-Soon),홍성언(Hong, Sung-Eon) 한국산학기술학회 2009 한국산학기술학회논문지 Vol.10 No.3

본 연구에서는 지적재조사사업의 추진이 지연되고 있는 원인을 사업의 홍보부족에 의한 국민공감대 형성미흡에 있다고 판단하였다. 그래서 이러한 문제를 해결하고자 허튼의 PR모델을 이용하여 지적재조사사업의 홍보 방안을 제시하여 보고자 하였다. 연구의 성과로서, 3차원의 6개 PR 실무 모델을 기초로 하여 각각의 홍보 실무에 적합하도록 총 31가지의 홍보수단에 따른 방법이 제시되었다. 그런데 일부 허튼의 PR모델이 지적재조사사업의 성격과 부합되지 않는 부분이 도출되어 이를 재조사사업의 성격에 부합하도록 새로이 모델을 재정립하여 제시하였다. 본 연구의 성과는 향후 지적재조사사업의 조속한 시행을 위한 대국민 공감대 형성에 기반을 마련하는데 일조할 수 있을 것으로 기대된다. This study is aimed at looking into the PR method of cadastral re-survey, and at looking for the reason of the delay of cadastral re-survey project. We thought that the reason why the cadastral re-survey project was delayed was a lack of a national agreement on it owing to an insufficient PR. So, to solve this question, we proposed an alternative plan for the PR method of cadastral re-survey, using Hutton’s PR model. As a result of a study, a total of 31 PR methods was made which were apt for every practical PR on the basis of 6 three-dimensional models of PR practice. But, some of Hutton’s PR models proved to be unfit for the cadastral re-survey project. Therefore, we formed and proposed a new model to apt for the cadastral re-survey project. The result of this study is expected to be of help in getting a foundation to form a national agreement on the quick operation of a upcoming cadastral re-survey project.

한국어업공동체의 성립과 존립양태에 관한 조사연구 - 어촌계를 중심으로 -

1. In Korean fishing villages, a living organism has been formed. It is based upon a strong co-operative union, which might be found in co-operative production systems and joint ceremonies. This organism has been transformed to fishing village association (0-Chon Gae), which also plays an important role in the lives of fishermen at present. What is the origin of this co-operative association? Why does the association play such an important role in fishing villages? It is serving to the enhancement of fichermen`s life condition? And what is the historical relationship between fishing village community and the fishing village association of today? Korea has been proud of her abundant gift of nature in marine industry. However, our efforts devoted to the exploitation of the gift have been weak, and industrial revolution in the filed of fishery was not accomplished. Naturally, our fishing villages have suffered from overpopulation and vicious circle of low productivity and low income. Then, what is the socio-economic basis of overpopulation in the midst of poverty in Korean fishing villages? In my view, it might have been derived from the common fishery which is bases on joint ownership of fishing grounds that are the most important means of production of fishing industry. Therefore, to make a thorough-going analysis on formation, evolution, discomposition, and the present situation of fishing village community will surely serve for the modernization of Korean fishery. 2. It seems to me that water exploitation began with the settlement of Korean people in the Korean peninsula. Even though they were gathering only seaweeds in the coasts, there must have been some orders and systems in their society. The first form of fishery management is believed to take the form of joint undertaking, but it was subsidiary to that agriculture in the coastal villages, In the old age, the fishery was not specialized and not seperated from agriculture, and fiching village community was not formed as an independent organization. The development of social division of labour, the improvement of technology, and the increasing demand for marine products based on growth of population, however, made fishery an independent occupation. At the same time, coastal village which had also worked as an agricultural village changed into pure fishing village. In the course of the development of Korean people, chronological estimation of the time when the fishing village community was established, is not possible. But the community is assumed to be founded at the time when pure fishing villages of the seashore were formed. Such a fishing village is presumed to be made in the later period of Korea Dynasty which was provided with feudalistic centeralization of administration. This fishing village community has been evolved in conjunction with the development of division of labour , technical improvement, the change of socio-economic systems, and at present the community is transformed to the fishing village association (0-Chon Gae) that is legalized. 3. There few reference books on the management of common fishery. Therefore, we must take the recourse to field survey. As a result, the following three types of operation of common fishery are pointed out. a. The original form of fishing village community is found in the fishing villages of remote islands, of which the main and important products are seaweeds. Therefore common fishery is operating in the form of the harmonious teamwork of villagers, with the joint ownership of the means of production including fishing grounds under the communal restraints, which could be seen in the villages of mediaeval Europe. b. However, the improvement of fishing technique brought about a change and discompostion to the common fishery. The degree of discomposition of common fishery is closely related to the capital inputs in the fishery. In the coastal marine production, the common fishing system of that fishery has been changed

한국수산업의 구조분석 - 1946년 ~ 1965년의 추이를 중심으로 -

박광순 ( Kwang Soon Park ) 한국경제학회 1967 經濟學硏究 Vol.15 No.1

1. Fishery is one of the important industries in Korea. It earns a lot of valuable foreign money every year. The annual exports of fishery reach 20 percent of total amount of Korean exports. However, it is said that the characteristics of fishery in Korea are its low productivity and low income. These characteristics are not because of the unsuitableness of physical environment concerning fishery in Korea, but because of the insufficiency of man`s effort to develop it. This means the structual deficiency of Korean fishery. This study is purposed to analysis the structure of Korean fishery with emphasis on its transition from 1946 to 1965. It is a well-known fact that the physical environment for fishery in Korea is very suitable for it. Our country is a peninsula surrounded by seas on three sides, having a long coast line reaching 26,000 kilometers and a very wide continental shelf amounting to about 500,000 square-kilometers. The neighbouring waters of Korea have also fitting temperature, and the tides are interchaged properly on the seas. At the same time, they contain abundant marine resources, such as fishes of about 854 species, shell fish and other molluse fishes of about 1000 species, and seaweeds of about 400 species. Judging from these points, we may say that the physical environment for fishery in Korea is a gift of nature. On the contrary, man`s effort to develop those resources had been very lukewarm and stagnant till the opening of the port at the end of the 19th century. With the opening of the port Japanese fishermen advanced to the Korean seas, and they contributed somewhat to the development of fishery in Korea at the technical side. Occupying the leadership of fishing in the neighbouring waters of Korea, they made Korean fishermen fall into the external stagnation of minor scale household management. This is one of the important reasons why Korean fishery has not developed continuously, and also the reason why Korean fishery has not escaped from the stagnant situation of low productivity and law income. These characteristics are due to the structural defects of fishery mentioned as below. Here are the significance and necessity of analysis to the structure of fishery in Korea. 2. At the first, we are going to analyze the production structure of fishery, secondly, the management sructure of fishery, and lastly its circulation structure. The important characteristics of the production structure of Korea fishery are as follows; First the fishing boats which are the most important means of production of the fishery are very little quantitively. As many we see at the following Table 1, the number of the fishing boats including fish-carrier amounts to 51,052 vessels at the end of 1965. It does show that the percapita fishing boatsare only 0.04 vessels. ◁표 삽입▷(원문을 참조하세요) Source: The Bank of Korea. Bureau of Fisheries, Ministry of Agriculture and Forestry. The number of fishing boats has been increased from 48,837 vessels in 1946 to 51,052 vessels in 1965. The speed and rate of growth of fishing boat is lagging far behind the growth of fisheries population. The rate of growth of fishing boat is estimated to reach only to 4.5 percent during twenty years. On the other hand the fishery population has increased by 234.5 percent since 1946. It means that Korean fishery has been sinking year by year. ◁표 삽입▷(원문을 참조하세요) Source: Bureau of Fisheries, Ministry of Agriculture and Forestry. Second the most of fishing boats are also small in scale and non-powered wooden boats. As we see at the Table 1, the average tonnge of Korean fishing boats in 1965 is only 3.98 tons. Although powered boats form 14.8 percent of all the fishing ships, most of them are made of wood. As we may see at the Table 2, the ships less than 5 tons form 85.6 percent of all the fishing boats. On the contrary, the ships more than 50 tons form only 1.1 percent of them. These prove the fact that the productive power of Kore

이러닝(E-Learning) 이용동기와 이용만족도에 영향을 미치는 요인에 관한 연구

박광순(Kwang-soon Park) 사이버커뮤니케이션학회 2006 사이버 커뮤니케이션 학보 Vol.19 No.1

본 연구는 대학생들의 e-러닝 이용동기 구조와 e-러닝과 관련된 각 요인은 e-러닝 이용만족도에 어떤 영향을 미치는가를 규명하기 위해 수행되었다. e-러닝 이용만족도에 영향을 미치는 요인에 관한 분석에 있어서는 심리적 변인인 이용동기 요인과 구조적 변인인 기술적, 내용적, 관리적, 학습자적, 조직적 요인 등을 독립변인으로 이용하였다. 또한 이들 변인 간 상관관계에 대한 분석도 실시하였다. 분석결과 이용동기는 학습정보 교류의 용이성, 학습과정의 용이성, 도구적 편리성, 학습공간의 개인성, 학습공간의 자유성, 시간적 편리성, 학습규칙의 자유성, 평가절차의 편리성, 일과의 병행성, 비의도성 등과 같이 10개의 요인이 추출되었다. 상관관계 분석에 있어서는 각 요인 간 상관관계가 비교적 높게 나타났다. 이용만족도에 대한 분석에서는 독립변인으로 투입된 모든 요인이 e-러닝 이용만족도에 영향을 미치는 것으로 나타났다. 따라서 대학생들은 e 러닝과 관련한 다양한 요인들을 상관적으로 활용하여 이용만족도를 형성한다고 할 수 있다. This paper aims to examine two questions 「What is the college students' use motive of e-learning?」 and 「How does the use motive have an effect on the use satisfaction?」. In an analysis of the factors that influence on the use satisfaction of e-learning, the factor of the use motive which is a psychological variable and the factors of technique, management, content, learner and organization which are structural variables have been used as an independent variable. Also, an analysis on 'what correlative relationship is formed among these variables' has been carried out. As a result of analysis, 10 factors were extracted. They are the easiness of information exchange for a learning, the easiness of a learning-process, the facility of tool-using, the individuality of space for a learning, the freedom of space for a learning, the convenience of time-using, the freedom of rule for a learning, the easiness of a evaluation-process, the parallel of a daily work and an unintentionality. Also, in an analysis of the use satisfaction, it is shown that all factors used as an independent variable have an influence. In an analysis of the correlative relationship, it is shown that the correlative relationship among all factors is relatively deep. Accordingly, it can be said that college students have their use satisfaction by correlatively using the various factors related with the e-learning.

LALR(1) 분석에서의 Conflict의 효율적인 추적

박광순(Kwang Soon Park),최광무(Kwang Moo Choe),박우전(Woo Jun Park) 한국정보과학회 1989 정보과학회논문지 Vol.16 No.4

LALR(1) 분석에서 발생하는 conflict의 원인을 찾아 제거하는 일은, 적지않은 LR(0) 상태들을 일일이 따라가고, 또 프로덕션을 검사해야 하는 매우 번거로운 작업이다. DeRemer와 Pennello는 conflict의 원인을 알려주는 정보(추적)를 파서 생성 시스템이 특정한 양식으로 출력하는 방법을 제시하였다. DeRemer와 Pennello의 추적 계산 방법에서는, lookahead 집합의 계산을 위하여 구성한 방향 그래프를 이용하여 추적을 구성하는 일부 요소를 쉽게 계산하지만, 비효율적인 측면을 가지고 있다. 본 논문에서는 박철희등의 새로운 LALR 해석논리에 기초하는 효율적인 새로운 추적 계산 방법을 제시하였다. 제안된 새로운 방법은, lookahead 집합의 계산을 위하여 계산된 넌터미널들 사이의 관계를 효과적으로 이용하여, 보다 효율적으로 추적을 계산한다. 기존의 방법과 제안된 새로운 방법을 KAIST 파서 생성 시스템에 구현하고, 몇개의 문법에 대하여 실험을 하여, 새로운 방법이 기존의 방법보다 효율적임을 보였다. Tracing of conflicts manually is not so easy in LALR(1) analysis; It involves troublesome tracing of LR(0) states and/or examination of productions in the grammar. DeRemer and Penello suggested an automatic tracing method, where information called trace which shows sources of conflicts, is produced in a predefined form. In the original method of computing traces, a relation needed in computing lookahead sets is used to find out the items which make the conflict symbol be included in the lookahead set of a reducible item. In this thesis, the trace computation method is re-examined under new formalism of Park et al., and a more efficient method based on the formalism is proposed. Both the old and new method are Implemented on KAIST Parser Generating System (KPGS), and experimental results for the comparison of the two method are presented.
