The main purpose of the present study is to survey the major iudexing bulletins of national nature in Korea, to define such problem areas as lacunae, duplicates and limitation in coverage in the indexing services currently available in Korea, and to make some suggestions for action for improving the existing indexing services in the light of general principles and the tradition and constraints unique to Korea. The major findings and conclusions reached at this study are summarised as follows: (A) A new indexing bulletin of general nature covering the entire field needs to be created in each of the following fields without an established indexing service available for the outcome of research and development activities in Korea. (1) Philosophy (2) Religion (3) Pure sciences (4) Art (5) Language (6) Literature (7) History (B) A new specialised indexing bulletin needs to be created in each of the following fields where indexing services are heavily utilised but no, or only partial, indexing service is available. (1) Social sciences (a) Statistics (b) Sociology (c) Folklore (d) Military science (2) Pure sciences (a) Mathematics (b) Physics (c) Chemistry (d) Astronomy (e) Geology (f) Mineralogy (g) Life sciences (h) Botany (i) Zoology (3) Applied sciences (a) Medicine (b) Agriculture (c) Civil engineering (d) Architectural engineering (e) Mechanical engineering (f) Electrical engineering (g) Chemical engineering (h) Domestic science (C) Publication of the indexing bulletins suggested in A and B above may be ideally carried on by a qualified and dependable learned society established in the respective fields and designated by the Minister of Education, and should be financially supported from the public fund under the provisions of Art. 27 of the Scientific Research Promotion Act of 1979. (D) The coverage and contents of the four indexing bulletins in the field of banking and financing published by the Library of the Bank of Korea are similar and considerably duplicated. It is, therefore, suggested that the four indexing bulletins are combined in one to form a more comprehensive and efficient bibliographical tool in the field and it is further developed into a general guide to the literature produced in the entire field of economics in Korea by gradually expanding its subject coverage. (E) For the similar reasons stated in D, the Index to the Articles on North Korea and the Catalogue of Theses on North Korea, both publisheds by the Ministry of Unification Library, are suggested to make into one. The Index to the Articles of the Selected North Korean Journals and the Index to the Articles of the North Korean Journals in Microfilm Housed in the Ministry of Unification Library, both published by the same Library, are also suggested to be combined in one. (F) The contents of the Catalogue of the Reports Submitted by Government Officials Who Have Travelled Abroad, published by the National Archives are included in the Index to the Information Materials Related to Government Administration, published by the National Archives. The publication of the former is hardly justified. (G) The contents of the Index to Legal Literature published by the Seoul National University Libraries and those of the Law Section of the Index to Scholastic Works published by the National Central Library are nearly identical. One of the two indexes should cease to be published. (H) Though five indexes are being published in the field of political science and four in the field of public administration, their subject coverage is limited. Naturally, these indexes are little usable to many other researchers in the two fields. A comprehensive index covering all the specialised areas in each field needs to be developed on one or all the existing indexes. (I) It is suggested that the Catalogue of the Scholastic Works on Curricula published by the National Central Library expands its subject coverage to become a more usable and effective index to all the researchers in the field of education. (J) The bimonthly Index to Periodical Articles and the specialised index by subject series published by the National Assembly Library, and the Index to Scholastic Works published by the National Central Library are expected to increase their coverage and frequency of publication to be used more effectively and more efficiently by all users in all fields till the indexing bulletins suggested in this study will fully be available in Korea.

비정형 데이터인 한국농수산대학 신입생 자기소개서에서 의미 있는 정보를 추출하기 위하여 핵심적인 역할을 하는 단어의 중요도를 평가하는 TF-IDF 가중치를 기초로 한 언어네트워크분석을 하였다. TF-IDF 가중치에 의한 핵심단어는 문항 1에서는 '농업', '수학', '공부', '문제', '친구', 문항 2에서는 '동아리', '식물', '친구', '농업', '작물', 문항 3에서는 '친구', '동아리', '의견', '갈등', '관리', 문항 4에서는 '버섯', '곤충', '아버지', '농업', '농장' 등으로 나타났다. 또한 빈도수는 낮은 단어이지만 핵심단어로 나타난 단어를 보면 문항 1에서는 '수학', '자격증', '성적', '영어', '과학', 문항 2에서는 '식물', '작물', '공부', '쓰레기', '발표', '실험', 문항 3에서는 '동아리', '청소', '봉사', '갈등', '봉사활동', 문항 4에서는 '버섯', '곤충', '양식', '한우', '조경' 등으로 나타났다. 단어들 간의 관계를 시각적으로 분석이 가능한 언어네트워크분석 결과 매개중심성이 높은 단어는 문항 1에서는 '이유', '고등학교', '재학', 문항 2에서는 '쓰레기', '고등학교', '학교', 문항 3에서는 '중요', '오해', '완성', 문항 4에서는 '가공', '사료', '농가'로 나타났다. 연결정도중심성은 문항 1에서는 '고등학교', '탐구', '성적', 문항 2에서는 '쓰레기', '정리', '수업시간', 문항 3에서는 '의견', '회의', '봉사활동', 문항 4에서는 '가공', '공간', '실습'으로 나타났다. 매개중심성 값이 클수록 네트워크의 중앙에 위치하고, 두 범주 사이의 관계가 강할수록 서로 근거리에 위치한다. 연결정도중심성이 클수록 노드의 크기가 크게 나타나며, 노드 연결선은 단어들의 동시 출현 빈도가 높을수록 edge가 굵게 나타났다. 동시 출현 빈도가 높은 즉 상관관계가 높은 단어 조합은 '자격증 - 취득', '문제 - 해결', '과학 - 생명', '오해 - 양보' 등으로 나타났다. 단어 기반의 계층적 클러스터링 기법에 의하여 단어 간 인접, 상호 관계를 계층적으로 나타낸 클러스터 덴드로그램으로 군집의 개수를 결정하였다. 단어들의 군집 간 비유사도의 차이가 큰 군집을 구한 결과 문항 1은 2개, 문항 2와 문항 4는 4개, 문항 3은 5개의 군집으로 분류할 경우 군집내 응집력이 높고, 군집 간 이질성이 큰 적절한 군집을 구할 수 있었다.

In order to understand basic data for improving the fishing system and fishing vessel structure in coastal improved stow net fishery, a questionnaire survey and on-site hearing were conducted from May 10 to June 11, 2019 to analyze opinions on the improvement of operation status and fishing vessel structure. The questionnaire survey consisted of ten questions on the operation status of coastal improved stow net fishery and six questions on the improvement of fishing vessel structure, and the results of each question were analyzed by the region, the captain's age, the captain's career and the age of fishing vessel. As a result of analyzing opinions on the operation status of the coastal improved stow net fishery, it was found that the average time required for casting net was 32.8 to 33.0 minutes and that the average time required for hauling net was 41.0 to 42.2 minutes which took 10 to 12 minutes more than for casting net. The most important work requiring improvement during fishing operation (the first priority) were 'hauling net operation,' 'readjustment and storage of fishing gear,' and 'fish handling' and the hardest factor in fishing management were in the order of 'reduction of catch,' 'labor shortage' and 'rising labor costs.' The most institutional improvement that is most needed in coastal improved stow net fishery was an 'using fine mesh nets.' Most of the respondent to the questions on the experience in hiring foreign crews was 'either hiring or willing to hire foreign crews,' and the average number of foreign crews employed was found to be 2.3 to 2.4 persons. The most important reason for hiring (or considering employment) foreign crews was 'high labor costs.' The degree of communication with foreign crews during fishing operation were 'moderate' or 'difficult to direct work.' The most important problem in hiring foreign crews (the first priority) was an 'illegal departure.' As the survey results on the opinion of structural improvement of coastal improved stow net fishing vessel, the degree of satisfaction with fishing vessel structure related to fishing operation was found to be somewhat unsatisfactory, with an average of 3.3 points on a five-point scale. The inconvenient structure of fishing vessel in possession (the first priority), the space needed most for the construction of new fishing vessel (the first priority) and the space considered important for the construction of new fishing vessel (the first prioprity) was a 'fish warehouse.' The most preferred equipment for the construction of new fishing vessel were 'engine operation monitoring' and 'navigation safety devices.' The average size (tonnage class), the average horse power and the average total length of fishing vessel for proper profit and safety fishing operation was between 13.8 and 14.0 tonnes, 808.3 to 819.5 H.P. and 23.4 to 23.5 meters, respectively. The results of the operation status of coastal improved stow net fishery and the requirement for improving the fishing vessel structure are expected to be provided as basic data for reference when we build or improve the fishing vessel.
