Recently, numerous documents have been made available electronically. Internet search engines and digital libraries commonly return query results containing hundreds or even thousands of documents. In this situation, it is virtually impossible for users to examine complete documents to determine whether they might be useful for them. For this reason, some on-line documents are accompanied by a list of keywords specified by the authors in an effort to guide the users by facilitating the filtering process. In this way, a set of keywords is often considered a condensed version of the whole document and therefore plays an important role for document retrieval, Web page retrieval, document clustering, summarization, text mining, and so on. Since many academic journals ask the authors to provide a list of five or six keywords on the first page of an article, keywords are most familiar in the context of journal articles. However, many other types of documents could not benefit from the use of keywords, including Web pages, email messages, news reports, magazine articles, and business papers. Although the potential benefit is large, the implementation itself is the obstacle; manually assigning keywords to all documents is a daunting task, or even impractical in that it is extremely tedious and time-consuming requiring a certain level of domain knowledge. Therefore, it is highly desirable to automate the keyword generation process. There are mainly two approaches to achieving this aim: keyword assignment approach and keyword extraction approach. Both approaches use machine learning methods and require, for training purposes, a set of documents with keywords already attached. In the former approach, there is a given set of vocabulary, and the aim is to match them to the texts. In other words, the keywords assignment approach seeks to select the words from a controlled vocabulary that best describes a document. Although this approach is domain dependent and is not easy to transfer and expand, it can generate implicit keywords that do not appear in a document. On the other hand, in the latter approach, the aim is to extract keywords with respect to their relevance in the text without prior vocabulary. In this approach, automatic keyword generation is treated as a classification task, and keywords are commonly extracted based on supervised learning techniques. Thus, keyword extraction algorithms classify candidate keywords in a document into positive or negative examples. Several systems such as Extractor and Kea were developed using keyword extraction approach. Most indicative words in a document are selected as keywords for that document and as a result, keywords extraction is limited to terms that appear in the document. Therefore, keywords extraction cannot generate implicit keywords that are not included in a document. According to the experiment results of Turney, about 64% to 90% of keywords assigned by the authors can be found in the full text of an article. Inversely, it also means that 10% to 36% of the keywords assigned by the authors do not appear in the article, which cannot be generated through keyword extraction algorithms. Our preliminary experiment result also shows that 37% of keywords assigned by the authors are not included in the full text. This is the reason why we have decided to adopt the keyword assignment approach. In this paper, we propose a new approach for automatic keyword assignment namely IVSM(Inverse Vector Space Model). The model is based on a vector space model. which is a conventional information retrieval model that represents documents and queries by vectors in a multidimensional space. IVSM generates an appropriate keyword set for a specific document by measuring the distance between the document and the keyword sets. The keyword assignment process of IVSM is as follows: (1) calculating the vector length of each keyword set based on each keyword weight; (2) preprocessing and parsing a target document that does not have keywords; (3) calculating the vector length of the target document based on the term frequency; (4) measuring the cosine similarity between each keyword set and the target document; and (5) generating keywords that have high similarity scores. Two keyword generation systems were implemented applying IVSM: IVSM system for Web-based community service and stand-alone IVSM system. Firstly, the IVSM system is implemented in a community service for sharing knowledge and opinions on current trends such as fashion, movies, social problems, and health information. The stand-alone IVSM system is dedicated to generating keywords for academic papers, and, indeed, it has been tested through a number of academic papers including those published by the Korean Association of Shipping and Logistics, the Korea Research Academy of Distribution Information, the Korea Logistics Society, the Korea Logistics Research Association, and the Korea Port Economic Association. We measured the performance of IVSM by the number of matches between the IVSM-generated keywords and the author-assigned keywords. According to our experiment, the precisions of IVSM applied to Web-based community service and academic journals were 0.75 and 0.71, respectively. The performance of both systems is much better than that of baseline systems that generate keywords based on simple probability. Also, IVSM shows comparable performance to Extractor that is a representative system of keyword extraction approach developed by Turney. As electronic documents increase, we expect that IVSM proposed in this paper can be applied to many electronic documents in Web-based community and digital library.

조류인플루엔자와 구제역 같은 동물감염병은 거의 매년 발생하며 국가에 막대한 경제적 사회적 손실을 일으키고 있다. 이를 예방하기 위해서 그간 방역당국은 다양한 인적, 물적 노력을 기울였지만 감염병은 지속적으로 발생해 왔다. 최근 빅데이터와 딥러닝 기술을 활용하여 감염병의 예측모델을 개발하고자 하는 시도가 시작되고 있지만, 실제로 활용가능한 모델구축 연구와 사례보고는 활발히 진행되고 있지 않은 실정이다. KT와 과학기술정보통신부는 2014년부터 국가 R&D사업의 일환으로 축산관련 차량의 이동경로를 분석하여 예측하는 빅데이터 사업을 수행하고 있다. 동물감염병 예방을 위하여 연구진은 최초에는 차량이동 데이터를 활용한 회귀분석모델을 기반으로 한 예측모델을 개발하였다. 이후에는 기계학습을 활용하여 좀 더 정확한 예측 모델을 구성하였다. 특히, 2017년 예측모델에서는 시설물에 대한 확산 위험도를 추가하였고 모델링의 하이퍼 파라미터를 다양하게 고려하여 모델의 성능을 높였다. 정오분류표와 ROC 커브를 확인한 결과, 기계 학습 모델보다 2017년 구성된 모형이 우수함을 확인 할 수 있었다. 또한 2017에는 결과에 대한 설명을 추가하여 방역당국의 의사결정을 돕고 이해관계자를 설득할 수 있는 근거를 확보하였다. 본 연구는 빅데이터를 활용하여 동물감염병예방시스템을 구축한 사례연구로 모델주요변수값, 이에따른 실제예측성능결과, 그리고 상세하게 기술된 시스템구축 프로세스는 향후 감염병예방 영역의 지속적인 빅데이터활용 및 분석 모델 개발에 기여할 수 있을 것이다. 또한 본 연구에서 구축한 시스템을 통해 보다 사전적이고 효과적인 방역을 할 수 있을 것으로 기대한다.

This study was undertaken to meet more fully the demands for improved training of library personnel, occasioned by the rapidly changing roles and functions of libraries as they try to adapt to the vast social, economic and technological changes currently in progress in the Korean society. The specific purpose of this research is to develop a standard curriculum at the batchelor's level that will properly equip the professional personnel in Korean libraries for the changes confronting them. This study started with the premise that to establish a sound base for curriculum development, it was necessary first to determine what concepts, knowledge, and techniques are required for professional library personnel to perform it at an optimal level of efficiency. Explicitly, it was felt that for the development of useful curricula and courses at the batchelor's level, a prime source of knowledge should be functional behaviours that are necessary in the job situation. To determine specifically what these terminal performance behaviours should be so that learning experience provided could be rooted in reality, the decision was reached to use a systems approach to curriculum development, which is an attempt to break the mold of traditional concepts and to approach interaction from an open, innovative, and product-oriented perspective. This study was designed to: (1) identify what knowledge and techniques are required for professional library personnel to perform the job activities in which they are actually engaged, (2) to evaluate the educational needs of the knowledge and techniques that the professional librarian respondents indicate, and (3) to categorise the knowledge and techniques into teaching subjects to present the teaching subjects by their educational importance. The main data-gathering instrument for the study, a questionnaire containing 254 items, was sent to a randomly selected sample of library school graduates working in libraries and related institutions in Korea. Eighty-three librarians completed and returned the questionnaire. After analysing the returned questionnaire, the following conclusions have been reached: (A) To develop a rational curriculum rooted in the real situation of the Korean libraries, compulsory subjects should be properly chosen from those which were ranked highest in importance by the respondents. Characters and educational policies of, and other teaching subjects offered by, the individual educational institution to which a given library school belongs should also be taken into account in determining compulsory subjects. (B) It is traditionally assumed that education in librarianship should be more concerned with theoretical foundations on which any solution can be developed than with professional needs with particulars and techniques as they are used in existing library environments. However, the respondents gave the former a surprisingly lower rating. The traditional assumption must be reviewed. (C) It is universally accepted in developing library school curricula that compulsory subjects are concerned with the area of knowledge students generally need to learn and optional subjects are concerned with the area to be needed to only those who need it. Now that there is no such clear demarcation line provided in librarianship, it may be a realistic approach to designate subjects in the area rated high by the respondents as compulsory and to designate those in the area rated low as optional. (D) Optional subjects that were ranked considerably higher in importance by the respondents should be given more credits than others, and those ranked lower might be given less credits or offered infrequently or combined. (E) A standard list of compulsory and optional subjects with weekly teaching hours for a Korean library school is presented in the fourth chapter of this report.

본 논문은 한국중소기업학회 40년의 역사적 흐름 속에서 창업생태계 연구 동향을 조명하고, 생산적 창업생태계 조성에 필요한 생태투입·산출요인에 관한 측정지표 개발 방향을 고찰하기 위해 수행되었다. '중소기업연구'의 창업생태계 연구 동향을 살펴본 결과, 선행연구는 생산적 창업생태계 조성과 다양한 생태투입요인에 대한 관리적 중요성을 강조하고 있다. 그러나 생태투입요인과 기업가정신으로 대변되는 생태산출요인 간 인과성을 검증하려는 실증연구에 필요한 측정모형 및 변수개발을 다루는 탐색적 연구는 실무·정책적 요구를 충족하지 못하고 있었다. 경험적 사실에 근거하여 창업생태계 성공요건을 규명하는 사례연구의 불균형적 발전은 연구 결과의 일반화와 효과적 실무·정책적 대안을 제안하는 데 한계가 있다. 국가·지역 경제성장을 견인하는 혁신동력으로써 생산적 창업생태계의 조성과 효율적 운영이 중요한 오늘날, 향후 실증연구에서 활용 가능한 생태요인 측정모형의 개발이 절실하다. 이에 본 연구는 기존의 [투입→산출→결과→성과] 프로세스를 적용하여, 생태투입·산출요인을 중심으로 창업생태계 측정 모형을 개념화하였다. 우선, 선행연구를 기반으로 생태투입요인(재정적·지식·제도적·사회적 자본)을 체계화하고, 생태산출요인은 설립, 혁신 및 성과기준 기업가정신으로 개념화하여 측정 가능한 변수로 도출하였다. 또한, 향후 실증연구에서 생태투입·산출요인 측정 시 활용 가능한 데이터베이스를 제안하고, 각 데이터의 특성을 검토하였다. 본 연구가 제안한 창업생태계 측정지표는 생태요인 간 인과성을 검증하려는 후속 연구에서 활용 가치가 높을 것으로 기대된다.

최근에는 지식재산권의 국제적 이용이 보편화되면서 라이센스 계약 관련 분쟁에 있어 다국적 요소가 개입되는 경우가 많아 실제 분쟁의 해결에 있어서도 준거법의 결정이 가장 첨예한 쟁점이 되고 있다. 특히 2011년 7월 한-EU FTA가 발효됨에 따라 우리나라와 유럽 각국 사이에 경제적 사회적 교류가 활발해지면서 그로 인한 법적 분쟁 또한 증가할 것으로 예상된다. 이러한 상황을 고려할 때 국제적 지식재산권 이용 계약과 관련하여 유럽연합(EU)의 준거법 결정 원칙에 대한 연구가 필요하다. 지식재산권 라이센스 계약과 관련하여 발생하는 국제분쟁에 있어서의 준거법 결정을 위해서는 기본적으로 국제사법 원칙에 의한 유형화가 필요하며 이때 지식재산권 라이센스 계약은 그 성질상 계약의 문제로 유형화된다. 유럽연합(EU)의 경우에는 라이센스 계약상의 쟁점 판단을 위한 준거법 결정을 위하여 기본적으로 로마 I 규정(the Rome I Regulation)의 적용을 검토하여야 한다. 그런데 분쟁의 대상이 되는 계약이 체결된 시점에 따라 국제사법 일반원칙, 로마협약(1980), 로마 I 규정 등 각각의 경우에 적용되는 규범이 달라지므로 계약 체결 시점을 파악하는 것이 가장 우선되어야 하고, 이들 중 로마 I 규정은 2009년 12월 17일부터 체결된 계약에 적용된다. 계약상의 분쟁에 관한 준거법 결정에 있어서는 기본적으로 당사자의 합의에 의한 준거법의 지정이 널리 허용되지만, 당사자의 합의에 의하여 준거법을 결정할 수 없는 경우에는 국제사법 이론상 '객관적 연결 방식'에 의하여 준거법이 결정된다. 이러한 원칙을 반영하여 로마 I 규정 제4조 제1항은 계약의 유형에 따른 준거법 결정 원칙을 제시하고 있지만 지식재산권 라이센스 계약이 해당되는 규정은 없다. 결국 로마 I 규정 제4조 제2항이 검토되어야 하고 로마 I 규정 제4조 제3항에 의하여 해당 계약이 더 밀접한 관련을 가지는 국가가 있는 경우에는 이 국가의 법이 준거법으로 적용된다. 이들 규정에 의하여서도 라이센스 계약의 준거법을 결정할 수 없는 경우에는 최종적으로 로마 I 규정 제4조 제4항에 의하여 해당 계약과 가장 밀접한 관련을 가지는 국가의 법이 준거법으로 결정된다. 이러한 로마 I 규정을 중심으로 지식재산권 라이센스 계약의 준거법 결정 원칙에 대한 연구를 수행함으로써 향후 우리나라와 유럽연합 국가들이 준거법 결정의 연결점으로서 작용할 수 있는 관련 국제계약 분쟁의 해결을 위하여 보다 체계적이고 효과적인 대응책을 마련할 수 있을 것으로 생각되며, 우리나라 국제사법 규정을 적용함에 있어서도 보다 풍부한 이론적 기초를 제공할 수 있을 것으로 기대된다.

The success of the family planning program in Korea is reflected in the decrease in the growth rate from 3.0% in 1962 to 2.0% in 1971, and in the decrease in the fertility rate from 43/1,000 in 1960 to 29/1,000 in 1970. However, it would be erroneous to attribute these reductions entirely to the family planning program. Other socio-economic factors, such as the increasing age at marriage and the increasing use of induced abortions, definitely had an impact on the lowered growth and fertility rate. Despite the relative success of the program to data in meeting its goals, there is no room for complacency. Meeting the goal of a further reduction in the population growth rate to 1.3% by 1981 is a much more difficult task than any one faced in the past. Not only must fertility be lowered further, but the size of the target population itself will expand tremendously in the late seventies; due to the post-war baby boom of the 1950's reaching reproductive ages. Furthermore, it is doubtful that the age at marriage will continue to rise as in the past or that the incidence of induced abortion will continue to increase. Consequently, future reductions in fertility will be more dependent on the performance of the national family planning program, with less assistance from these non-program factors. This paper will describe various approaches to help to the solution of these current problems. 1. PRACTICE RATE IN FAMILY PLANNING In 1973, the attitude (approval) and knowledge rates were quite high; 94% and 98% respectively. But a large gap exists between that and the actual practice rate, which is only 3695. Two factors must be considered in attempting to close the KAP-gap. The first is to change social norms, which still favor a larger family, increasing the practice rate cannot be done very quickly. The second point to consider is that the family planning program has not yet reached all the eligible women. A 1973 study determineded that a large portion, 3096 in fact, of all eligible women do not want more children, but are not practicing family planning. Thus, future efforts to help close the KAP-gap must focus attention and services on this important large group of potential acceptors. 2. CONTINUATION RATES Dissatisfaction with the loop and pill has resulted in high discontinuation rates. For example, a 1973 survey revealed that within the first six months initial loop acceptance. nearly 50% were dropouts, and that within the first four months of inital pill acceptance. nearly 50% were dropouts. These discontinuation rates have risen over the past few years. The high rate of discontinuance obviously decreases the contraceptive effectiveness. and has resulted in many unwanted births which is directly related to the increase of induced abortions. In the future, the family planning program must emphasize the improved quality of initial and follow-up services. rather than more quantity, in order to insure higher continuation rates and thus more effective contraceptive protection. 3. INDUCED ABORTION As noted earlier. the use of induced abortions has been increase yearly. For example, in 1960, the average number of abortions was 0.6 abortions per women in the 15-44 age range. By 1970. that had increased to 2 abortions per women. In 1966. 13% of all women between 15-44 had experienced at least one abortion. By 1971, that figure jumped to 28%. In 1973 alone, the total number of abortions was 400,000. Besides the ever incre.sing number of induced abortions, another change has that those who use abortions have shifted since 1965 to include- not. only the middle class, but also rural and low-income women. In the future. in response to the demand for abortion services among rural and low-income w~men, the government must provide and support abortion services for these women as a part of the national family planning program. 4. TARGET SYSTIi:M Since 1962, the nationwide target system has been used to set a target for each method, and the target number of acceptors is then apportioned out to various sub-areas according to the number of eligible couples in each area. Because these targets are set without consideration for demographic factors, particular tastes, prejudices, and previous patterns of acceptance in the area, a high discontinuation rate for all methods and a high wastage rate for the oral pill and condom results. In the future. to alleviate these problems of the methodbased target system. an alternative. such as the weighted-credit system, should be adopted on a nation wide basis. In this system. each contraceptive method is. assigned a specific number of points based upon the couple-years of protection (CYP) provided by the method. and no specific targets for each method are given. 5. INCREASE OF STERILIZA.TION TARGET Two special projects. the hospital-based family planning program and the armed forces program, has greatly contributed to the increasing acceptance in female and male sterilization respectively. From January-September 1974, 28,773 sterilizations were performed. During the same time in 1975, 46,894 were performed; a 63% increase. If this trend continues, by the end of 1975. approximately 70,000 sterilizations will have been performed. Sterilization is a much better method than both the loop and pill, in terms of more effective contraceptive protection and the almost zero dropout rate. In the future, the. family planning program should continue to stress the special programs which make more sterilizations possible. In particular, it should seek to add the laparoscope techniques to facilitate female sterilization acceptance rates. 6. INCREASE NUMBER OF PRIVATE ACCEPTORS Among the current family planning users, approximately 1/3 are in the private sector and thus do not- require government subsidy. The number of private acceptors increases with increasing urbanization and economic growth. To speed this process, the government initiated the special hospital based family planning program which is utilized mostly by the private sector. However, in the future, to further hasten the increase of private acceptors, the government should encourage doctors in private practice to provide family planning services, and provide the contraceptive supplies. This way, those do utilize the private medical system will also be able to receive family planning services and pay for it. Another means of increasing the number of private acceptors, IS to greatly expand the commercial outlets for pills and condoms beyond the existing service points of drugstores, hospitals, and health centers. 7. IE&C PROGRAM The current preferred family size is nearly twice as high as needed to achieve a stable poplation. Also, a strong boy preference hinders a small family size as nearly all couples fuel they must have at least one or more sons. The IE&C program must, in the future, strive to emphasize the values of the small family and equality of the sexes. A second problem for the IE&C program to work. with in the: future is the large group of people who approves family planning, want no more children, but do not practice. The IE&C program must work to motivate these people to accept family planning And finally, for those who already practice, an IE&C program in the future must stress continuation of use. The IE&C campaign, to insure highest effectiveness, should be based on a detailed factor analysis of contraceptive discontinuance. In conclusion, Korea faces a serious unfavorable sociodemographic situation- in the future unless the population growth rate can be curtailed. And in the future, the decrease in fertility will depend solely on the family planning program, as the effect of other socio-economic factors has already been maximumally felt. A second serious factor to consider is the increasing number of eligible women due to the 1950's baby boom. Thus, to meet these challenges, the program target must be increased and the program must improve the effectiveness of its current activities and develop new programs.

재범예측은 70년대 이전부터 전문가들에 의해서 꾸준히 연구되어온 분야지만, 최근 재범에 의한 범죄가 꾸준히 증가하면서 재범예측의 중요성이 커지고 있다. 특히 미국과 캐나다에서 재판이나 가석방심사 시 재범 위험 평가 보고서를 결정적인 기준으로 채택하게 된 90년대를 기점으로 재범예측에 관한 연구가 활발해졌으며, 비슷한 시기에 국내에서도 재범요인에 관한 실증적인 연구가 시작되었다. 지금까지 대부분의 재범예측 연구는 재범요인 분석이나 재범예측의 정확성을 높이는 연구에 집중된 경향을 보이고 있다. 그러나 재범 예측에는 비대칭 오류 비용 구조가 있기 때문에 경우에 따라 예측 정확도를 최대화함과 동시에 예측 오분류 비용을 최소화하는 연구도 중요한 의미를 가진다. 일반적으로 재범을 저지르지 않을 사람을 재범을 저지를 것으로 오분류하는 비용은 재범을 저지를 사람을 재범을 저지르지 않을 것으로 오분류하는 비용보다 낮다. 전자는 추가적인 감시 비용만 증가되는 반면, 후자는 범죄 발생에 따른 막대한 사회적, 경제적 비용을 야기하기 때문이다. 이러한 비대칭비용에 따른 비용 경제성을 반영하여, 본 연구에서 비대칭 오류 비용을 고려한 XGBoost 기반 재범 예측모델을 제안한다. 모델의 첫 단계에서 최근 데이터 마이닝 분야에서 높은 성능으로 각광받고 있는 앙상블 기법, XGBoost를 적용하였고, XGBoost의 결과를 로지스틱 회귀 분석(Logistic Regression Analysis), 의사결정나무(Decision Trees), 인공신경망(Artificial Neural Networks), 서포트 벡터 머신(Support Vector Machine)과 같은 다양한 예측 기법과 비교하였다. 다음 단계에서 임계치의 최적화를 통해 FNE(False Negative Error)와 FPE(False Positive Error)의 가중 평균인 전체 오분류 비용을 최소화한다. 이후 모델의 유용성을 검증하기 위해 모델을 실제 재범예측 데이터셋에 적용하여 XGBoost 모델이 다른 비교 모델 보다 우수한 예측 정확도를 보일 뿐 아니라 오분류 비용도 가장 효과적으로 낮춘다는 점을 확인하였다.

This survey was made for a month starting from November 15 to December 15, 1977 covering 711 students taking the junior. (3rd-yea.) and the senior. (4th-year) at nine college of nursing in Seoul concerning their perception and Attitude toward the profession of nursing, motive for the necessity of learning, environment of study, attitude of study and particulars relevant with study performance, particulars of library, references and reading, assignments and particulars of the degree of confidence for the learning achievement. Through the survey of the above Particulars, the following results were obtained by classifying all subject matters and by analysing motive of the selection of their course, awarding or not awarding of scholarships. 1. General characteristics: it was revealed that 406 students (57.1%) were attending at the junior. while 305 students (42.9%) were taking the senior. Thus, the total number was 711 and their average age was 21.4 years. Their dwelling category was; 73.9 percent of them resided at their parent's home, 214 students (30.1%) were awarded with scholarships. The reason to be attracted by nursing science was the possibility of continuing social life after graduation (43.5%). 2. Their perception and attitude toward the profession of nursing: According to the perception of profession by the students of each grade, students of the 4th grade showed comparatively strong conception. Also, students of the 4th grade showed more positive attitude in the purchase and reading of magazines relative with the science of nursing, in the reading of Code for Nurses and in their interest in the activity of nursing field. For the necessity of mission of nurse, 97.7 percent of the entire number of students covered responded to necessity. For the necessity of the particular humanity and particularity in the character of nurses, 95.8 percent of those students responded to necessity. By the each grade, students of the 4th grade showed more response. 3. As to professional field desired after completing the professional course: 57 percent of those students desired for clinician nurse while 55 percents desired for community health-nurse. 4. As to the environment of study: they were mostly satisfied with their present residential environment. However, they complained of inconvenience at their lecture-halls. Students of the 3rd grade showed more complain. As to their attitude toward the adjustment of environment of study, they showed a affirmative response. As to the opinion of factors which interfere with their study, comparatively strong response was showed in their scepticism in the science of nursing, insufficient comprehension in general learning, relation with professors n4 discrepancy in the method of study. According to opinions of students at each grade, students of the 4th grade showed more scepticism. 5. Particulars relative with their attitude and performance of study : As to their knowledge of the objectives of their study of subject, the majority was to study with a partial knowledge of the objectives of their study. As to the plan of study, a low percentage indicated management of routine life under regular scheduling. Students of the 4th grade responded to rather planned life. As to time spent in independent study, response to concentrated study when necessary was stronger than that to regular daily study. Students of the 4th grade showed stronger response to regular study than that of the 3rd grade. As to the contents of their note-taking, 67.4 percents of those students responded to such regulatory procedure performing in the lecture-hall as they listen to lectures. 17.3 percents of those students showed response to adding supplementary informations from references to what was entered in choir note-taking at their lecture-halls. 6.
