Several goodness-of-fit test statistics have been proposed for a multinomial logit regression model; however, the properties of the proposed tests were not adequately studied. This paper evaluates three different goodness-of-fit tests using grouping strategies, proposed by Fagerland et al. (2008), Bull (1994), and Pigeon and Heyse (1999). In addition, Pearson (1900)'s method is also examined as a reference. Simulation studies were conducted to evaluate the four methods in terms of null distribution and power. A real data example is presented to illustrate the methods.

In order to newly expand and define the concept of "strategic servitization" based on Industry 4.0, this study tried to evaluate the existing status of domestic and foreign servitized manufacturing and investigated the servitization cases of some leading overseas companies. In addition, we chose 250 samples of manufacturing firms listed on KOSDAQ and collected a vast amount of data regarding servitized manufacturing, such as the current status about new businesses, profit model, and financial fluctuations of each company. Based on these data, we classified the main types of manufacturing-service convergence into a $2{\times}2$ framework and derived a new strategic servitization model for each type of signature. Furthermore, we divided the sample corporations into three groups, which are pure manufacturer, servitized firm, and strategic servitized firm, and through the mutual comparison of the real sales amounts and the estimated sales amounts by time-series extrapolation analysis, we statistically proved that the service sales of strategic servitized firms give positive impacts on ROA when compared with those of the other two groups. Finally, we selected 12 leading domestic strategic-servitized firms, interviewed them in depth, and not only organized the issues during this process and their solutions by categories but also suggested the policy demands for strategic servitization.

GUI 환경에서 작업에 필요한 여러 윈도우를 작은 화면에 동시에 나타내기 위하여 많은 윈도우 시스템이 오버래핑 윈도우 관리 전략을 채택하고 있다. 하지만 개별 윈도우를 독립적으로 다룸으로써 작업전환시 개별 윈도우 단위의 정렬을 하여야 하는 등의 불필요한 작업을 수행하게 된다. 특히 본 연구의 목표 기종인 PCS 정보단말기는 320*240 크기의 소형 디스플레이 장치를 가지고 있기 때문에, 가시적인 작업 단위의 윈도우 그룹에 대한 빈번한 변경을 다루는데 부적합하다. 따라서 본 논문에서는 작업 단위로 윈도우를 그룹화하는 방식으로 윈도우를 관리함으로써 보다 효율적으로 작업 전환을 수행하는 방법을 제안하고, 성능 평가를 통하여 제시된 방법의 효율성을 보여준다.

The contemporary incidents, in which hatred toward the socially disadvantaged is the cause, are constantly evoking archivists' social role and responsibility. This study notes the documentation strategy as a way to document contemporary incidents involving the socially disadvantaged as the main actors. The purpose of this study is to propose the documentation strategy for documenting contemporary incidents around the L Comics issue. As a theoretical study, it examines the concept and significance of contemporary incidents documenting and documentation strategies. Through an analysis of the issue's overview, features, key events, and focus groups, the context of the issue was identified, and relevant online records were investigated. In addition, through interviews with stakeholders and experts, opinions on the documentation strategy of the L Comics issue were collected. In conclusion, the study discusses the objectives, direction, principle, category, subject and considerations for documenting the issue, and proposes the documentation strategy for it.

이 논문에서는 데이터마이닝의 클러스터링을 이용한 경보 데이터 축약기법을 제안한다. 제안된 클러스터링 기반 경보데이터 축약기법은 데이터간의 유사성을 이용한 경보 데이터의 그룹화를 통해 생성된 모델을 이용하여 새로운 경보 데이터에 대한 분류를 자동화할 수 있다. 이것은 과거에 탐지된 공격의 형태뿐만 아니라 새로운 혹은 변형된 경보의 분류나 분석에도 이용할 수 있다. 또한 생성된 클러스터의 생성 원인의 분석을 이용한 클러스터 간의 시퀀스의 추출을 통해 사용자가 공격의 순차적인 구조나 그 이면에 감추어진 전략을 이해하는데 도움을 주며, 현재의 경보 이후에 발생 가능한 경보들을 예측할 수 있다.

3차원 공간에서 항행기법을 이용한 사용자 인터페이스는 정보의 시각화를 통한 편리성과 연속적인 제어를 통한 자연스런 대화가 가능하다는 장점이 있다. 또한, 응용범위와 표현력의 증가, 사용자의 이해를 증진시킬수 있는 점등 잇점이 많다. 하지만 개념의 미확립. 구현상의 복잡성 등의 문제점으로 인해 아직까지는 개발이 부진한 상태에 있다. 본 논문에서는 이런 3차원 항행기법을 그룹웨어 응용프로그램이 요구하는 사용자관리, 도메인 관리 및 세션관리에 적용해 봄으로써 공간상에 시각정보를 나타내는 방법에 관한 구체적인 면을 설명한다.
