1975년(年) 3월(月), 4년반(年半) 동안의 Chemical Abstracts 색인(索引)과 온-라인이 가능(可能)한 CA Condensates를 비교(比較)하였다. 두가지 데이터 베이스를 함께 이용(利用)하여 검색(檢索)하는 방법(方法)이 가장 효율적(效率的)이지만 실예(實例)에서 보는 바와 같이 CA Condensates를 검색(檢索)하는 것이 보다 실용적(實用的)이다. System Development Corp 사(社) (SDC)에 설치(設置)되어 있는 온-라인 형태(形態)인 CHEMCON과 CHEM7071을 Chemical Abstracts 색인(索引)과 비교(比較)하였다. 대부분(大部分)의 Chemical Abstracts 이용자(理容者)들은 Chemical Abstracts 책자나 우가색인(累加索引)에는 친숙(親熟)하지만 CA Condensates는 아마도 그리 친숙(親熟)하지 못할 것이다. CA Condensates는 서지적 사항을 기계(機械)로 읽을 수 있는 형태(形態)로 되어 있고 Chemical Abstracts에 따라서 색인(索引)되므로 매주 발행되는 Chemical Abstracts 책자의 뒷 부분이 있는 색인(索引)과 같이 우리에게 가장 친숙(親熟)한 형태(形態)로 되어 있다. Chemical Abstracts가 현재(現在) 사용(使用)하고 있는 데이터 데이스이지만 본고(本稿)에서는 Index와 Condensates를 둘 다 데이터 베이스로 정의(定義)한다. Condensates가 미국(美國)의 Chemical Abstracts Service 기관으로부터 상업적(商業的)으로 이용(利用)할 수 있게 되자 여러 정보(情報)센터에서는 이용자(利用者)들의 프로 파일을 뱃취방식(方式)으로 처리(處理)하여 매주 나오는 자기(磁氣)테이프에서 최신정보(最新情報)를 검색(檢索)하여 제공(提供)하는 서어비스 (SDI)를 시작하였다. 어떤 정보(情報)센터들은 지나간 자기(磁氣)테이프들을 모아서 역시 뱃취방식(方式)으로 소급(遡及) 문헌검색(文獻檢索) 서어비스를 한다. 자기(磁氣)테이프를 직접 취급(取扱)하는 사람들을 제외(除外)하고는 대부분(大部分) Condensates를 아직 잘 모르고 있다. 소급(遡及) 문헌검색(文獻檢索)은 비용이 다소 비싸고 두서없이 이것 저것 문헌(文獻)을 검색(檢索)하는 방법(方法)은 실용적(實用的)이 못된다. 매주 나오는 색인(索引)에 대해서 두 개나 그 이상의 개념(槪念)이나 물질(物質)을 조합(組合)하여 검색(檢索)하는 방법(方法)은 어렵고 실용적(實用的)이 못된다. 오히려 주어진 용어(用語) 아래에 있는 모든 인용어(引用語)들을 보고 초록(抄錄)과의 관련성(關連性)을 결정(決定)하는 것이 때때로 더 쉽다. 상호(相互) 작용(作用)하는 온-라인 검색(檢索)을 위한 Condensates의 유용성(有用性)은 많은 변화를 가져 왔다. 필요(必要)한 문헌(文獻)만을 검색(檢索)해 보는 것이 이제 가능(可能)하고 어떤 항목(項目)에 대해서도 완전(完全)히 색인(索引)할 수 있게 되었다. 뱃취 시스팀으로는 검색(檢索)을 시작해서 그 결과(結果)를 받아 볼 때 까지 수시간(數時間)에서 며칠까지 걸리는 번거로운 시간차(時間差)를 이제는 보통 단 몇 분으로 줄일 수 있다. 그리고 뱃취 시스팀과는 달리 부정확하거나 불충분한 검색방법(檢索方法)은 즉시 고칠 수가 있다. 연속적인 뱃취 형태의 검색방법(檢索方法)에 비해서 순서(順序)없이 온-라인으로 검색(檢索)하는 방법(方法)이 분명(分明)하고 정확(正確)한 장점(長點)이 있다. CA Condensates를 자주 이용(移用)하게 되자 그의 진정한 가치(價値)에, 대해 논의(論義)가 있었다. CA Condensates의 색인방법(索引方法)은 CA Abstract 책자나 우가색인(累加索引)의 방법(方法)보다 확실히 덜 체계적(體系的)이고 철저(徹底)하지 못하다. 더우기 두 데이터 베이스는 중복(重複)것이 많으므로, 중복(重複)해서 검색(檢索)할 가치(價値)가 없는지를 결정(決定)해야 한다. 다른 몇 개의 데이터 베이스와 CA Condensates를 비교(比較)한 논문(論文)들이 여러 번 발표(發表)되어 왔는데 일반적(一般的)으로 CA Condensates는 하위(下位)의 데이터 베이스로 나타났다. Buckley는 Chemical Abstracts의 색인(索引)이 CA Condensates 보다 더 좋은 문헌 (데라마이신의 제법에 관해서)을 제공(提供)한 실례(實例)를 인용(引用)하였다. 죠오지대학(大學)의 Search Center는 CA Condensates가 CA Integrated Subject File 보다 기능(機能)이 못하다는 것을 알았다. CA Condensates의 다른 여러 가지 형태(形態)들을 또한 비교(比較)하였다. Michaels은 CA Condensates를 온-라인으로 검색(檢索)한 것과 매주 나오는 Chemical Abstracts 책자의 색인(索引)은 수작업(手作業)으로 검색(檢索)한 것을 비교(比較)한 논문(論文)을 발표(發表)하였다. 그리고 Prewitt는 온-라인으로 축적(蓄積)한 두 개의 상업용(商業用) CA Condensates를 비교(比較)하였다. Amoco Research Center에서도 CA Condensates와 Chemical Abstracts 색인(索引)의 검색결과(檢索結果)를 비교(比較)하고 CA Condensates의 장점(長點)과 색인(索引)의 장점(長點), 그리고 사실상(事實上) 서로 동등(同等)하다는 실례(實例)를 발견(發見)하였다. 1975년(年) 3월(月), 적어도 4년분(年分)의 CA Condensates와 색인(索引)(Vols 72-79, 1970-1973)을 비교(比較)하였다. 저자(著者)와 일반(一般) 주제(主題) 대한 검색(檢索)은 Vol 80 (Jan-June, 1974)을 사용(使用)하여 비교(比較)하였다. CA Condensates는 보통 세분화(細分化)된 복합물(複合物)을 검색(檢索)하는 데 불편(不便)하다. Buckly가 제시(提示)한 실례(實例)가 그 대표적(代表的)인 예(例)이다. 그러나, 다른 형태(形態)의 검색실예(檢索實例)(단체저자(團?著者), 특허수탁저(特許受託著), 개인저자(個人著者), 일반적(一般的)인/세분화(細分化)된 화합물(化合物) 그리고 반응종류(反應種類)로 실제적(實際的)인 검색(檢索)을 위한 CA Condensates의 이점(利點)을 예시(例示)하였다. 다음 실례(實例)에서 CHEMCON과 CHEM7071은 CA Condensates를 온-라인으로 입력(入力)시킨 것이다.

Objectives: This study aims to identify health status and health risks among female marriage immigrants to Korea and to provide a basis for public health strategies to address their health issues. Methods: The participants of the study were 3,069 immigrant wives. The health examination was conducted by the Korea Association of Health Promotion (KAHP) in 2008. The participants also completed self-administered questionnaires on demographic characteristics, health-related behaviors and mental health. Results: Patterns of immigrant women's health problems differed by age and country of origin. Behavior patterns also differed by their heritage, age, and years of residence in Korea. Generally Vietnamese women fell in lower ranges of disease prevalence and health risk factors in the participant group and Japanese women presented most healthy eating habits. Filipina women showed relatively high disease prevalence than any other group. Conclusion: Immigration to Korea by marriage is relatively a new phenomenon, thus continuing surveillance and research are needed to identify health risks, behavior patterns, and their relationships. Interventions and policies for the health of migrant wives, their children and families are required.

Recently, the number of social media users has increased rapidly because of the prevalence of smart devices. As a result, the amount of real-time data has been increasing exponentially, which, in turn, is generating more interest in using such data to create added value. For instance, several attempts are being made to analyze the relevant search keywords that are frequently used on new portal sites and the words that are regularly mentioned on various social media in order to identify social issues. The technique of "topic analysis" is employed in order to identify topics and themes from a large amount of text documents. As one of the most prevalent applications of topic analysis, the technique of issue tracking investigates changes in the social issues that are identified through topic analysis. Currently, traditional issue tracking is conducted by identifying the main topics of documents that cover an entire period at the same time and analyzing the occurrence of each topic by the period of occurrence. However, this traditional issue tracking approach has two limitations. First, when a new period is included, topic analysis must be repeated for all the documents of the entire period, rather than being conducted only on the new documents of the added period. This creates practical limitations in the form of significant time and cost burdens. Therefore, this traditional approach is difficult to apply in most applications that need to perform an analysis on the additional period. Second, the issue is not only generated and terminated constantly, but also one issue can sometimes be distributed into several issues or multiple issues can be integrated into one single issue. In other words, each issue is characterized by a life cycle that consists of the stages of creation, transition (merging and segmentation), and termination. The existing issue tracking methods do not address the connection and effect relationship between these issues. The purpose of this study is to overcome the two limitations of the existing issue tracking method, one being the limitation regarding the analysis method and the other being the limitation involving the lack of consideration of the changeability of the issues. Let us assume that we perform multiple topic analysis for each multiple period. Then it is essential to map issues of different periods in order to trace trend of issues. However, it is not easy to discover connection between issues of different periods because the issues derived for each period mutually contain heterogeneity. In this study, to overcome these limitations without having to analyze the entire period's documents simultaneously, the analysis can be performed independently for each period. In addition, we performed issue mapping to link the identified issues of each period. An integrated approach on each details period was presented, and the issue flow of the entire integrated period was depicted in this study. Thus, as the entire process of the issue life cycle, including the stages of creation, transition (merging and segmentation), and extinction, is identified and examined systematically, the changeability of the issues was analyzed in this study. The proposed methodology is highly efficient in terms of time and cost, as it sufficiently considered the changeability of the issues. Further, the results of this study can be used to adapt the methodology to a practical situation. By applying the proposed methodology to actual Internet news, the potential practical applications of the proposed methodology are analyzed. Consequently, the proposed methodology was able to extend the period of the analysis and it could follow the course of progress of each issue's life cycle. Further, this methodology can facilitate a clearer understanding of complex social phenomena using topic analysis.

우리나라의 천문 관측의 기록의 역사는 삼국시대 이전 선사시대까지 거슬러 올라간다. 선사시대에는 천문 현상을 바위나 건축 유물에 기록을 남기고 역사를 기록하기 시작한 이후에는 일반 역사 기록 속에 항상 함께 기록하고 있다. 특히 동양은 역사기록 자체가 인간이 남긴 자취뿐만 아니라 하늘과 땅에 일어나는 다양한 자연 현상도 함께 동시에 남겼다. 고대로부터 인간은 하늘과 땅과 항상 유기적인 관계를 갖는다고 믿었기 때문이다. 우리나라는 정사로서 가장 오래된 역사 기록인 삼국사기와 삼국유사에 일식, 혜성 출현, 별똥과 유성우, 달과 행성 운행, 초신성 관측 등 250회 이상의 천문 기록이 나타나며 대부분 실제로 일어났던 사실을 그대로 기록하고 있다. 그 후 고려사와 조선왕조실록에는 이루 헤아릴 수 없을 정도로 많은 천문 기록을 남기고 있다. 이러한 천문 기록뿐만 아니라 일찍부터 중국으로부터 역법을 도입하여 천체 운행을 이용하여 우리 생활에 필요한 시각법을 사용하고 달력을 제작하였다. 특히 달과 태양의 운행 원리를 파악하여 일식과 월식을 직접 추산하였다. 역법의 운용은 천체 운행의 원리를 이해하고 수학을 발전시키는데 큰 역할을 하였다. 이러한 천문 관측과 정확한 시각 체계를 유지하고 정밀한 역법을 사용하기 위해서는 끊임없이 천체를 정밀하게 관측할 필요성이 있다. 이를 위해 다양한 천문 관측기기를 개발하고 제작하였다. 천문 의기는 천체의 위치를 측정하고 천체의 운행을 이용하여 시각 체계를 유지 관리를 위해 필수불가결한 기기이다. 우리나라 천문학 발달의 네 가지 축인 천문(天文), 역법(曆法), 의상(儀象), 구루(晷漏)등은 조선 초기 세종시대 완성을 보게 되었다. 이는 단일 왕조가 이룬 업적으로 다른 문화권에서 볼 수 없을 정도의 우수한 과학 기술의 유산이다. 특히 칠정산내편과 외편의 완성은 중국의 역법에서 벗어나 독자적인 역법을 완성하려는 시도였다. 이 모든 것은 당시 이를 주도하던 세종대왕의 지도력과 천문학과 수학에 뛰어난 천문학자가 이룩한 업적이다. 그 후 조선 중기로 접어들면서 쇠퇴하다가 임진왜란과 병자호란을 겪으면서 거의 모든 과학기술의 유산이 파괴되거나 유실되었다. 조선 현종 이후에 세종시대의 유산을 복원하려는 노력 중에 중국을 통하여 서양의 천문학을 도입하게 되었다. 중국에 들어와 있던 서양 선교사들이 주도하여 중국의 역법 체계를 바꾸었다. 즉, 일식과 월식의 예측력이 뛰어난 시헌력을 만들어 사용하기 시작했다. 시헌력에는 서양의 대수학과 기하학을 이용한 다양한 수학적 기법이 사용되었다. 조선 후기에 이 시헌력을 익히기 위한 노력을 하는 과정에서 서양의 수학과 기하학을 접하게 되고 새로운 우주 체계를 도입하게 되었다. 특히 서양의 천문도와 지도 제작에 기하학의 투사법이 사용되어 복잡한 대수학적 계산을 단순화시켜 활용하였다. 조선 후기에 전문 수학자뿐만 아니라 많은 유학자들도 서양의 수학과 기하학에 깊은 관심을 갖고 연구하였다. 고천문학 전체를 조망해 볼 때 핵심은 현대의 천체물리학이 아니라 위치천문학이다. 따라서 고천문학을 연구하는데 필수적인 요소가 지구의 자전과 공전 운동에 의해서 일어나는 현상과 세차운동에 의한 효과를 정확하게 이해하고 있어야 한다. 그중에서도 구면천문학과 천체역학에 대한 원리를 알고 있는 상태에서 접근해야 한다. 고천문학의 중심인 천문(天文), 역법(曆法), 의상(儀象), 구루(晷漏) 등의 내용은 이러한 위치천문학이 그 기본 골격을 이루고 있다. 예를 들어 고려사의 천문 현상을 모아 놓은 천문지(天文志)와 일식과 월식 계산 원리가 들어있는 역지(曆志)를 연구하기 위해서는 위치천문학의 기본 개념 없이는 연구하는데 한계가 있다. 인문학을 전공하는 학자가 고천문을 연구하는데 가장 큰 걸림돌이 되는 점이 위치 천문학의 기본 개념 없이 접근하는 것이다. 심지어 조선시대 유학자들조차 저술한 많은 천문 관련 기록을 보면 상당부분 천체 운행 원리를 모르고 혼란스럽게 기록된 내용이 적지 않다. 우리나라 수학사를 연구할 경우 방정식 해법, 보간법, 삼각법, 일반 기하 원리에 대한 것을 연구하는데 큰 문제가 없다. 그러나 천문 현상이나 천문 의기 제작에 사용되는 수학은 천문 현상에 대한 원리를 모르면 접근하기 어렵게 된다. 수학사를 하더라고 기본적인 위치 천문학의 기본개념을 이해하고 있어야 폭 넓은 수학사 연구에 성과를 거둘 수 있다. 의외로 천문 현상 추산을 위해 사용되는 수학이나 기하학 원리가 수학사 연구에 중요한 요소가 된다. 더구나 한문으로 기록된 천문 내용을 한문 해독이 능숙한 학자라 하더라도 내용을 모르고 번역하면 도무지 무슨 내용인지 알아볼 수 없는 경우가 많다. 그래서 한문으로 된 천문 현상 기록이나 역법 관련 기록의 번역 내용 중에 많은 오역을 발견하게 된다. 문제는 한번 오역을 해 놓으면 몇 십 년이고 그대로 그 내용을 무비판적으로 인용하게 되고 사실로서 인정하는 오류를 범하게 된다. 이 때문에 우리 선조들이 남긴 고천문 관련 기록에 관한 이해는 우리 현대 천문학자의 역할이 대단히 크다.

Purpose: The purpose of our study is to provide useful information for the prevalence of obesity by the standard weight for height and the relationship of the body image to dieting methods for weight control in children. Methods: The survey was performed by an anthropometry and a special questionnaire on children in grades 5 to 6 at elementary schools from May to June 1997 in Kwangju city. Results: 1) Selected individuals were categorized into obese, normal, thin by the standard weight for height and body image. The prevalence of obesity by the standard weight for height was 19.5%, normal was 70.5%, thin was 10.1% in males and respectively 10.5%, 66.3%, 23.1% in females. The prevalence of obesity in regards to body image was 18.4%, normal was 58.4%, thin was 23.2% in males and respectively 24.5%, 58.6%, 16.9% in females. 2) The obese body image was 6.8% in normal and thin groups in males and 19.4% in females. The body image of obese children who do not perceive themselves as obese was 32.6% in males and 28.7% in females. 3) The standard body image was 88.8% as realized by themselves, 77.9% when they compared themselves to friends, 62.7% as told by parents, 56.8% as told by friends, and 29.9% when they compared themselves to celebrities. 4) The source of information for dieting treatment was 44% from radio and television, 30% from books, newspapers, magazines, 17% from family and 9% from friends and seniors. 5) The prevalence of dieting according to the standard weight for height was 18.0% in thin, 18.7% in normal and 36.7% in obese group in males and respectively 17.8%, 22.4%, 46.3% in females. There was a statistically significant correlation between males and females (p<0.0005). 6) The prevalence of dieting up to 2 weeks in the thin and normal groups as recognized by weight centile was 17.3% according to body image. The prevalence of dieting up to 2 weeks in the obese groups was 37.2% according to body image (p<0.001). Conclusion: We suggest that many students perceived their body size incorrectly and tried weight control. The incorrect perception of body size seems to cause the problem of failure to thrive, malnutrition etc. It is necessary for further study to find and prevent side effects by unnecessary weight control and to provide proper health education and management about obesity.

The joints in the jointed concrete pavement provide a control against transverse or longitudinal cracking at slab, which may be caused by temperature or moisture variation during or after hydration. Without control of cracking, random cracks cause more serious distresses and result in structural or functional failure of pavement system. However, joints nay cause distresses due to its inherent weakness in structural integrity. Thus, the evaluation at joint is very important. and the joint-related distresses should be evaluated reasonably for economic rehabilitation. The purpose of this paper was to develop an evaluation system at joints of jointed concrete pavement using finite element analysis program, ILLI-SLAB, and nondestructive testing device. FWD. To develop an evaluation system for JCP, a sensitivity analysis was performed using ILLI-SLAB program with a selected variables which might affect fairly to on the performance of transverse joints. The most significant variables were selected from precise analysis. An evaluation charts were made for jointed concrete pavement by adopting the field FWD data. It was concluded that the variables which most significantly affect to pavement deflections are the modulus of subgrade reaction(K) and the modulus of dowel/concrete interaction(G), and limiting criteria on the performance of joints at JCP are 300pci. 500,000 lb/in. respectively. Using these variables and FWD test, a charts of load transfer ratio versus surface deflection at joints were made in order to evaluate the performance of JCP. Practically, Chungbu highway was evaluated by these evaluation charts and FWD field data for jointed concrete pavement. For Chungbu highway, only one joint showed smaller value than limiting criterion of the modulus of dowel/concrete interaction(G). The rest joints showed larger values than limiting criteria of the modulus of subgrade reaction(K) and the modulus of dowel/concrete interaction(G).

The engraved line expression in metal crafts is a detailed technique of carving or decorating metal surfaces. This technique engraves a line using a tool on the surface of a metal craft. This technique was used extensively in articles made of various metal materials during the Goryeo Dynasty, and the range of patterns that could be expressed and the width of users was wide. In this paper, based on relics and literature, the concept of line representation of this engraving technique used in the metal crafts of the Goryeo Dynasty and the perceptions and terms of the Goryeo Dynasty were examined. In addition, the users engaged in this craft and the specific patterns and patterns of decoration were reviewed. Through these means, it was possible to confirm various aspects of a technique that was thought previously to involve just simple expression of lines using tools. In addition, through the literature, Geumseokmun Gate, and relics currently being transmitted, it was possible to confirm the utilization patterns of techniques used in various types of objects. Various uses have led to the combination with other metal craft techniques that were popular at the time, and while utilizing unique characteristics of the techniques, this maximized the molding of various patterns. In the meantime, it is true that the intaglio technique in metal crafts has not received much attention compared to the decoration techniques of other metal crafts, such as inlay, embossing, and openwork techniques in which decorative effects are maximized due to the recognition that the technique was used so widely in relics. However, the universality of the technique is premised on its wide use across all eras. As such, it was used in metal craft relics that reflect the various cultural characteristics of Korea and various cultural aspects that are currently passed down. On the one hand, technology has been passed down as a form of intangible heritage that embodies a longstanding craft culture which continues to the present in the fields of sculpture and intangible cultural properties. As such, the universality of Seongak contains many cultural meanings. In addition, the uniqueness of the technique is distinct, and it is deeply related to Goryeo, who was in charge of the use of technology and craftsmanship of the Joseon Dynasty and the metal craft technology that is currently handed down. I think research on future techniques should be continued in depth.

Purpose: The purpose of this study was to evaluate the quality and problems of Web sites for management of childhood and adolescent obesity. Methods: We evaluated 203 Web sites identified from the search engine, Korean Yahoo, using the word of 'childhood and adolescent obesity'. 203 Web sites were classified according to medical institutions, health information Web sites, beauty shops. etc. We surveyed whether childhood and adolescent obesity distinguished with adult obesity was considered, or not. and researched the unique managements of childhood and adolescent obesity including the cardinal treatment. Results: Of the 203 Web sites, 157(77.3%) provided detailed information about treatment of obesity, 46(22.7%) provided only simple information about one. The sites providing detailed information were composed of 52.2% of oriental medicine clinics, 35.0% of clinic & hospitals including pediatric hospitals. Distribution of the sites about management of childhood and adolescent obesity distinguished with adult's one was only 23% of oriental medicine clinics, but 93% of childrens hospitals. Conclusion: Without considering the speciality of childhood obesity, inaccurate information are distributing on internet web sites. It is necessary for concern and development of advertizing system on the internet distributing accurate information about treatment of childhood obesity.

Background: Vocabularies originating from Chinese characters constitute an important common factor in the medical terminologies used 3 eastern Asian countries; Korea, China and Japan. This study was performed to comparatively analyze the medical terminologies of these 3 countries in the field of cardiopulmonary bypass (CPB) and; thereby, facilitate further understanding among the 3 medical societies. Material and Method: A total of 129 English terms (core 85 and related 44) in the field of CPB were selected and translated into each country's official terminology, with help from Seoul National University Hospital (Korea), Tokyo Michi Memorial Hospital(Japan), and Yanbian Welfare Hospital and Harbin Children Hospital (China). Dictionaries and CPB textbooks were also cited. In addition to the official terminology used in each country, the frequency of use of English terms in a clinical setting was also analyzed. Result and Conclusion: Among the 129 terms, 28 (21.7%) were identical between the 3 countries, as based on the Chinese characters. 86 terms were identical between only two countries, mostly between Korea and Japan. As a result, the identity rate in CPB terminology between Korea and Japan was 86.8%; whereas, between Korea and China and between Japan and China the rates were both 24.8%. The frequency of use of English terms in clinical practices was much higher in Korea and Japan than in China. Despite some inherent limitations involved in the analysis, this study can be a meaningful foundation in facilitating mutual understanding between the medical societies of these 3 eastern Asian countries.
