  • 본 연구에서는 방송자료에 대한 지적 접근점을 제공하기 위한 방편으로, 뉴스 및 시사보도 프로그램의 내용 기술을 위한 패싯 분석 기법의 적용을 시도하였다. 랑가나단의 PMEST 기본 패싯에 기반하여, 보도 장르에 적합한 기본 패싯-'누가', '무엇을', '어떻게', '어디서', '언제'-을 생성하였으며, 보도 장르의 형식적 구조와 내용적 요소를 반영하여 패싯의 구성요소를 추출하였다. 이를 실제 방영한 시사보도 프로그램을 대상으로 적용해 본 결과, 본 연구에서 제안한 패싯이 보도 장르의 맥락적 요소를 잘 표현해주고 있었으며, 패싯의 적용은 특정 방송내용에 대한 식별을 증진시킬 것으로 기대되었다.

  • For any category with a distinguished collection of sequences, such as n-exangulated category, category of N-complexes and category of precomplexes, we consider its Grothendieck group and similar results of Bergh-Thaule for n-angulated categories [1] are proven. A classification result of dense complete subcategories is given and we give a formal definition of K-groups for these categories following Grayson's algebraic approach of K-theory for exact categories [4].

  • Pain management of postoperative patients or patients suffering from terminal cancer became one of the most important task of nurses in recent years. This study analyzed basic knowledge of 175 student nurses in Taegu on the pain assessment and management. The questionnaires included five areas : Assessment, pharmacological actions, medication, classification of opioids, and psychological dependence of analgesics. The results indicated that nursing students, in general, lacked knowledge on pain management : Correct responses on pain assessment varied between 9.7 and 100% , classification of opioids was in ranges of 61.7 to 95.4% ; Pharmacological actions was 16.6 to 80% : and medication was 14.9 to 85.7%. Less than 12.6% of students correctly identified the frequency of psychological dependence. These results suggested that the need of reinforcement on the pain management in formal nursing education.

  • The International Association of Classification Societies(IACS) can trace its original back to the International Conference on Load Lines of 1930 and was established in 1968. Long before the formal foundation of IACS, a number of working parties existed to carry out studies of specific topics concerning technical rules of classification. The general terms of reference of the working groups of IACS are to draft unified rules and regulations between Societies, to study safety standards at the request of the International Maritime Organization(IMO) and to prepare unified interpretations of technical regulations of international conventions. As an associate member since 1975, the Korean Resister of Shipping has been actively attending the meeting of IACS working parties. In this paper, summaries of major agenda of the working parties including history of unified requirements and relevant technical tendencies are explained for the purpose of providing better understanding of the rule development.

  • A recognition algorithm for Hangul is developed by structural analysis to Hangul in this theses. Four major procedures are proposed : preprocessing, type classification, separation of consonant and vowel, recognition. In the preprocessing procedure, the thinning algorithm proposed by CHEN & HSU is applied. In the type classification procedure, thinned Hangul image is classified into one of six formal types. In the separation of consonant and vowel procedure, starting from branch-points which are existed in a vowel, character elements are separated by means of tracing branch-point pixel by pixel and comparison with proposed templates. In the same time, the vowels are recognized. In the recognition procedure, consonants are extracted from the separated Hangul character and recognized by modified Crossing method. Recognized characters are converted into KS-5601-1989 codes. The experiments show that correct recognition rate is about 80%-90% and recognition speed is about 2-3 character persecond in three types of different input data on computer with 80386 microprocessor.

  • 본 논문은 한글문자 인식을 위하여 새로운 접촉소자의 분리 및 자획연결 특징추출 알고리즘을 제안하였다. 자소 접촉특징을 분석하여 자소접촉 형태별로 분류하고 자획연결특징 추출, 접촉자소의 분리, 문자형식 분류를 시행한다. 분리된 자소로부터 설정된 표준패턴으로 정규화하고 자소별 굴곡특징의 상대위치값으로 부터의 특징을 입력패턴으로 신경망을 이용하여 인식 실험을 하였다. 여기에서의 학습은 BEP 알고리즘을 이용하였다. 접촉자소의 분리, 형식분리, 자획연결특징 추출 및 인식 실험에서 제안된 알고리즘이 좋은 결과를 나타내었다.

  • 이 연구에서는 국제적으로 관심이 집중되고 있는 FSA를 선박의 화재 안전 분야에 도입하기 위한 준비과정으로 화재안전도의 가장 중요한 지표인 사망확률의 근거가 되는 피난계산을 실습선의 모의훈련에 의해 계산하여 피난시간의 계산 및 성능기준 화재의 안전설계를 검토하였다. 그 결과 승선인원과 대피 통로의 폭과는 일정한 상관관계가 있으며 최적의 폭을 산정할 수 있음을 보였다. 그러나 선박 내부의 좁은 통로와 선박의 종류에 따른 특수한 구조를 고려할 때 일괄적인 적용은 어렵다. 또한 대피시간을 모의실험에 의해 추정하고 유출계수를 구한 결과 공용실의 유출계수와 비교하여 기관실의 인명위험성이 약 4배이상 높게 나타났다.

  • Data Warehousing and OLAP (On-Line Analytical Processing) have turned into the key technology for comprehensive data analysis. Originally developed for the needs of decision support in business, data warehouses have proven to be an adequate solution for a variety of non-business applications and domains, such as government, research, and medicine. Analytical power of the OLAP technology comes from its underlying multidimensional data model, which allows users to see data from different perspectives. However, this model displays a number of deficiencies when applied to non-conventional scenarios and analysis tasks. This paper presents an attempt to systematically summarize various extensions of the original multidimensional data model that have been proposed by researchers and practitioners in the recent years. Presented concepts are arranged into a formal classification consisting of fact types, factual and fact-dimensional relationships, and dimension types, supplied with explanatory examples from real-world usage scenarios. Both the static elements of the model, such as types of fact and dimension hierarchy schemes, and dynamic features, such as support for advanced operators and derived elements. We also propose a semantically rich graphical notation called X-DFM that extends the popular Dimensional Fact Model by refining and modifying the set of constructs as to make it coherent with the formal model. An evaluation of our framework against a set of common modeling requirements summarizes the contribution.

  • 건설프로젝트에서 발생되는 리스크는 공기지연 및 비용증가에 큰 영향을 끼치기 때문에 다양한 리스크를 파악하기 위한 노력이 이루어지고 있다. 그러나 시공단계의 리스크 분석은 공종 및 수행단계에 국한되거나, 경험 의존적 의사결정이 주로 수행되고 있다. 데이터 기반의 분석도 일부 사례에 적용되고 있을 뿐이다. 따라서 본 연구에서는 시공사 또는 발주처에 중요한 요인들이 포함되어 있을 것으로 판단되는 수발신공문을 대상으로 군집분석과 Word2Vec 알고리즘을 적용하였다. 군집분석을 통해 6개 유형으로 1차 분류를 수행하였으며, Word2Vec을 통해 157개의 공문 발생 유형을 도출하였다. 도출된 연관어의 속성별 분석을 위하여 새로운 5개의 범주를 적용하였으며, 이를 통해 공문 발생 유형이 잠재적인 건설 리스크 요인으로 발전 가능한지 검토하였다. 텍스트 마이닝을 통한 3단계의 공문 발생 유형 분석 결과는 건설현장의 공정관리를 위한 기초 자료로써 도움 될 것으로 판단된다.

  • The purpose of this study was to understand the preference of fashion materials according to the degree of consciousness and satisfaction of body. A survey was conducted using the randomly selected 439 woman students in the twenties. The consciousness variable had three levels which were lean, medium, and obese shape for each whole, upper and lower body with self-consciousness. Also, satisfaction variable had three levels which were satisfying, average, and unsatisfying group. We analyzed the data using analysis of correlation, crosstabulation analysis, and analysis of variance including Duncan multiple test. The results were as follows: 1) There was the positive correlation between height, leg, and arm length, and each variable, and the negative correlation between back, hip, thigh, waist, lower leg, ankle, and upper arm, and each variable. Also, we could observe the pattern that the larger the head or the more the weight was, the lower the satisfaction of body was. 2) There were no strong correlation between breast and hand size and each variable. From the crossed classification, we could observe the trend that the smaller the breast was, the lower the satisfaction of body was. 3) There were the strong correlation between whole and upper body in consciousness degree and between whole and lower body in satisfaction. 4) The consciousness of the whole body was shown lean shape 23.4%. medium shape 49.2%, and obese shape 27.2%. For the satisfaction degree of the whole body, satisfaction was shown 6.8%, average 41.7% and unsatisfaction 51.4%, so the satisfaction group is very small. 5) From the analysis for the consciousness degree of the whole body, the preferred fashion materials were polyester and acetate in casual wear, linen, polyester, acryl, T/W, and polyurethan in formal wear, and cotton, nylon, TIC, and T/W in sports wear. There was significant difference in casual wear, formal wear, and sports wear, but, not in underwear and accessories among he consciousness groups. 6) From the analysis for the satisfaction degree of the whole body, the preferred fashion materials were linen, silk, and acetate in casual wear, cotton in underwear, polyurethane in formal wear, and nylon in sports wear. There was the significant difference in casual wear, underwear, formal wear and sports wear, but, not in accessories among the satisfaction groups.
