정보 기술이 적용된 장비 및 운영 시스템의 발달로 실시간 운영 데이터를 수집할 수 있게 되었으며, 현재 많은 터미널이 생산성 분석을 위해 상세한 작업이력을 추적하고 있다. 터미널 운영자는 수집된 작업이력 데이터를 통해 운영 중 발생하는 문제점들을 해결할 수 있는 방안을 도출하기 원하지만, 방대한 양의 자료를 수작업으로 분석하기는 쉽지 않다. 본 연구에서는 터미널 운영 중 획득된 작업이력을 바탕으로 터미널 운영자가 원하는 컨테이너 터미널의 성능지표를 손쉽게 도출하기 위한 방안을 제시한다. 이를 위해 다양한 컨테이너 터미널의 환경과 운영 방식, 운영 장비 등을 지원하기 위해 범용적으로 사용될 수 있는 형식 프레임워크(formal framework)를 고안하였다. 본 연구에서 제안하는 프레임워크는 컨테이너 처리 객체라는 개념을 기반으로 터미널 형태, 로그 데이터, 장비의 워크플로우, 통계 처리 및 보고서를 각각 정의하는 사용자 명세 부분으로 구성된다. 그리고 제안된 프레임워크를 기반으로 터미널 성능 분석 시스템을 개발하여 그 유효성을 검증하였다.

형식개념분석기법(FCA: Formal Concept Analysis)은 대상 도메인의 데이터를 사용자의 관점과 해석을 바탕으로 개념화함으로서 필요한 정보의 추출과 접근을 제공하기 위한 기법으로서 다양한 분야에서 널리 사용되고 있다. 그러나, 기존의 형식개념분석기법 지원 도구들은 대부분 객체와 속성간의 관계를 나타낸 One-valued context에 대한 분석만을 중점적으로 지원하고 있고, 다종다양한 값을 갖는 데이터들로 구성된 Many-valued context에 대한 분석을 충분히 지원하지 못하고 있다. 따라서, 본 논문에서는 다양한 값을 갖는 입력 데이터를 사용자의 목적에 맞도록 해석하여 간결화하기 위한 스케일링(Scaling) 알고리즘과 입력 데이터들로부터 개념을 추출하여 계층구조화하기 위한 알고리즘을 제안한다. 이와 같은 연구결과를 토대로 개념분석과 계층구조화를 위한 자동화 도구(FCA Wizard)를 개발하여, 실제 의료 분야에서의 적용사례를 소개한다.

Purpose - This study aims to investigate whether the buyer's participation in CSR activities can affect the informal cooperation and relationship beyond formal cooperation and relationship. Research design, data, and methodology - We defined the research model and selected variables(monitoring and contracts by the buyer, formal cooperation & relationship, and informal cooperation & relationship). After completing the questionnaire, we analyzed 319 manufacturing companies. Prior to the hypothesis testing, Exploratory factor analysis(EFA) and confirmatory factor analysis(CFA) were conducted to check for discriminant validity and convergent validity. Results - The stronger the buyer monitoring on the company's CSR activities, the more positive it affects the formal business cooperation. On the other hand, strong buyer monitoring did not affect formal business relationships. Therefore, even if buyers' monitoring of CSR activities is strong, it does not mean that the formal business relationship is improved, but it means that it is possible to improve the formal business cooperation. Conclusions - This study shows that the stronger the buyer monitoring on the supplier's CSR activities, the more positive it affects formal cooperation. It also demonstrates that formal business cooperation between the supplier and the buyer, that is, sharing goals and works for CSR activities, has a positive effect on relationships based on emotional exchange and commitment.

전통적인 방식의 예측모형 구축에서 사용되는 데이터는 주로 데이터베이스에 잘 보관되어 있는 정형데이터를 사용하였다. 하지만 지금의 상황은 스마트 시대의 도래로 인한 통신수단의 획기적인 발달로 비정형 데이터가 전체데이터의 80%를 상회하는 현실이다. 이러한 현실에서 기존의 방법대로 정형데이터 만을 이용하여 예측모형을 개발하면 예측모형의 신뢰성에 문제가 있을 것이다. 즉 전체데이터의 80%에 해당하는 비정형(SNS, 페이스북, 트위트, 이미지, 동영상 등)과 반정형(로그데이터)데이터를 반드시 포함하여 모형을 구축해야 만이 신뢰성을 현실화 시킬 수 있을 것이다. 본 논문에서는 예측모형 개발시 빅데이타 방법론을 적용하여 예측 모형의 신뢰성을 높이고, 데이터를 이용하여 제안된 방법과 전통적인 방법의 예측모형의 신뢰도를 비교 분석 하였다.

The purpose of this study was to propose a computer-based grading method for men's formal wear according to the sizing systems based on the size and dimension whereby manufactured men's formal wear can be classified. The following procedures were as follows : 1) We surveyed the sizing systems and the computer-grading methods that have been used and presently practiced by the domestic garment industry of the ready-made men's wear. 2) Using the survey data of the domestic men's ready-made clothing industry and that of the National Anthropometric Survey of Korea in 1997, we proposed the new sizing and grading systems of men's formal wear within the framework of the Korean Garment Industry's directions and the data of the domestic men's ready-made clothing industry. 3) The suitability of the new grading systems to the domestic garment industry were put to a wearing teat. The findings were as follows : 1) Survey of the domestic ready-made garment industry showed that each company classified its own manufactured goods according to its own sizing and grading systems. 2) The superiority of the grading system was been demonstrated by a high approval rate of the subjects who participated in the testing.

The condition of financial services in Indonesia is unique, based on various characteristics, behaviors, and preferences. Therefore, the study of finance and banking is interesting to study as a recommendation for government policies. This paper aims to analyze the barriers to accessing formal financial services in Indonesia and why informal financial services are preferred. This paper presents a case study of financial inclusion in selected provinces in Indonesia using the SOFIA dataset from the Ministry of National Development Planning. Overall, this data consists of 20,000 individuals from 4 provinces and 93 regions representing the population in eastern Indonesia. The analysis was carried out by processing individual-level cross-sectional data surveyed in 2017 using the probit binary logistic method. The results identify the individual barriers in accessing formal financial services, including account ownership, saving, and credit activities in the formal financial institutions, and amplify the image by analyzing what determinants affect people to choose informal institutions. We found that some individual characteristics such as age, gender, education, income, employment status, residence, and access to technology significantly affect the barrier to formal financial services in East Indonesia.

Purpose: This study identified the planning trends for formal and informal learning spaces in the college of medicine through literature reviews. And then, by the analysis of the actual condition of existing domestic facilities, It was organized the architectural planning baseline data and future directions for the formal and informal learning spaces in the college of medicine. Methods: This study was conducted using literature reviews on the existing medical education method and learning space planning. Subsequently on-site surveys and questionnaires were conducted at existing facilities. Results: In the past, learning space of the college of medicine was considered only a formal learning space such lecture rooms, labs. But lately it has been turned into a total learning concept that embraces shared learning spaces such as libraries, student spaces, amenities and common spaces such as lobbies and hallways. ① Formal learning spaces are composed of teaching and practice areas. Since It is the basic functions that comprise the college of medicine, this paper conducted a functional analysis based on the current operating system of the College of Medicine and provided baseline data on architectural planning such as function, layout, zoning, and detailed planning. ② The informal learning sharing space was divided into a library area and a student well-being and convenience area to analyze the real conditions of domestic medical college. In addition, by comparing the trends and differences in foreign medical colleges identified by literature analysis, this paper summarizes the need to revitalize informal learning spaces and their integration into formal learning spaces, architectural planning considerations, etc. Implications: the evolution of the learning method and the flexibility of the learning space bring about changes in the learning space.

Digital contents services are one of the topics that have been intensively studied in the media industry, where various semantic and ontology techniques are applied. However, query execution for ontology data is still inefficient, lack of sufficient extensible definitions for node relationships, and there is no specific semantic method fit for media data representation. In order to make the machine understand digital contents (DCs) data well, we analyze DCs data, including static data and dynamic data, and use ontology to specify and classify objects and the events of the particular objects. Then the formal representation method is proposed which not only redefines DCs data based on the technology of OWL/RDF, but is also combined with media segmentation methods. At the same time, to speed up the access mechanism of DCs data stored under the persistent database, an ontology-based DCs query solution is proposed, which uses the specified distance vector associated to a surveillance of semantic label (annotation) to detect and track a moving or static object.
