분석 및 설계단계의 산출물을 작성할 때는 대부분 정형화와 표준화를 따른다. 그러나 실제 시스템 개발현장에서는 단계별 산출물들의 개별적인 특성으로 인하여 모든 산출물간에는 연속적이며 자동화된 과정을 통해 산출물들이 작성될 수는 없다. 그 결과 작성된 개발 산출물간의 일관성이 유지되지 못하는 관계로 최종 산출물에서 여러 가지 문제가 야기됨을 알 수 있다. 그러므로 본 논문에서는 객체지향 방법론에 따라 개발되는 시스템에 대해 분석 및 설계단계의 산출물간 일관성을 유지하기 위한 방안을 제시하고, 이를 지원하기 위한 도구를 개발한다.

This study was designed to test the relationship between effectiveness of nursing organizations and structural and managerial variables of nursing organizations that are described in the Robbins Organizational theory model. The data were collected through self reported questionnaires from 605 nurses working in, and 782 patients hospitalized in, five tertiary hospitals in Seoul. Results showed that according to MANOVA there was a significant difference in nurses job satisfaction and patient satisfaction among the five hospitals. According to cluster analysis of the structural and managerial variables of nursing organizations, the five hospitals were divided into two clusters and there was no significant difference in nurses job satisfaction or patient satisfaction between the two clusters. According to canonical correlation analysis the formalization and centralization of structural variables were shown to be predicting variables for nurses job satisfaction, and the managing job design and managing Change of managerial variables were shown to be predicting variables for nurses job satisfaction.

Many empirical research surveys have supported that Organizational Citizenship Behavior (OCB) is influnced by or closely related with leadership styles. The first purpose of this study is to review the relationship between 2 leadership styles(employee-centered style, job-centered style) and 2 OCB factors(altruism, conscientiousness) as a criterion variable, and the second and primary purpose is to test the moderating effects of structural factors(formalization, centralization) and personal factors(growth needs, sex, age, tenure, rank, occupation, school career) between 2 leadership styles and 2 OCB factors. For the analytical purpose of this article, Fisher's Z-transformation and SGC(split groups correlations) methods were introduced. Generally 2 leadership styles are found to influence on altruism and conscientiousness respectively. Out of 36 cases, only 2 cases were significant in moderating effects. Based on empirical results, there is no moderating effects in conscientiousness. But altruism is found to more closely related with employee-centered leadership in low centralized group than on high centralized group, and more closely related with job-centered leadership in low growth-needs group than in high growth-needs group.

소프트웨어 재사용의 문제는 두 가지 측면에서 검토해 볼 수 있는 데, 하나는 이미 개발이 완료된 소프트웨어 컴포넌트를 조합하여 재사용하는 방법이고, 다른 한 가지는 소프트웨어들이 공통적으로 갖는 구조적인 패턴을 정의해서 재사용 하는 방법이다. 물론 이 두 가지가 소프트 웨어의 구조설계에 중요한 방법이긴 하지만, 이 두 방식의 차이점은 소프트웨어 컴포넌트는 프로그램 컨텐츠가 채워진 빌딩블록들을 재사용 하여 소프트웨어를 쉽게 구성하는 것인 반면, 소프트웨어 구조패턴은 빌딩블록의 내용보다는 빌딩블록의 틀, 즉 빌딩블록간의 연결을 통한 구조화에 더 관심이 있는 것이라고 하겠다. 논문은 후자의 경우와 같이 소프트웨어 응용에서 많이 발견되는 구조적인 소프트웨어 패턴을 분석하고 체계적으로 정의하여, 이 패턴들이 소프트웨어 구조 설계 시 유용하게 활용될 수 있도록 하는 데 목적을 두고 있다. 특히, 이제까지 소프트웨어의 구조적인 패턴을 설명하는 데 중요한 모델이 되어 왔던 소프트웨어 구조 스타일을 분석하고 정형화하여 다양한 응용의 소프트웨어 구조설계에 활용될 패턴형 컴포넌트를 정의하고자 한다.

The purpose of this study is to explore institutional frameworks to professionalize housing management in Korea. In particular, this research reviews the evolution of professional housing management and its institutional measures in a social constructionist perspective. The main method employed in the study is content analysis in which historical pathways in institutionalization of professional housing management are examined and a wide array of indices from secondary data are drawn out in relation to various actors. The findings show that a series of institutional measures were taken from 1970s to secure the professionalization of housing management ranging from introduction of housing management bylaws, placement of licensed housing managers, legal requirements of professionally managed housing estates, compulsory operation of long-term reserve funds, formation of residents' association, mandatory establishment of long-range maintenance planning, to standardization of multifamily housing management bylaws. Since the Multifamily Housing Management Ordinance of 1979 amended in 1980s, many institutional measures have been legally enforced and shaped contemporary practices of professional housing management such as an association for housing management companies, qualification of on-site housing management agents, national licensing examination for housing managers, an organization for licensed housing mangers, mandatory registration of housing management companies, disclosure of monthly housing management fees, and formalization of public assessment of housing management. In spite of the distinctive marks in the professionalization of housing management, more proactive and competitive approaches to the international professionalization need to be considered.

능동 데이터베이스에서의 규칙(rule)은 트리거하는 사건이 감지되면 자동으로 규칙을 트리거하여 데이터베이스의 상태변화에 대응하는 조치를 자동으로 수행한다. 이러한 능동 규칙은 자신을 포함한 서로 다른 규칙을 트리거 할 수 있으므로 종료하지 못하고 연속적으로 실행될 가능성이 있다. 이와 같은 문제는 규칙의 종료 분석을 통해 차단할 수 있으며 규칙의 종료 분석은 규칙의 컴파일 시간에 수행하는 것이 가장 효과적이다. 따라서 이 논문에서는 규칙 종료분석기를 내장한 규칙 컴파일러를 설계하고 그 수행 모델 및 알고리즘을 제안한다. 아울러 제안 모델의 핵심이라 할 수 있는 규칙 종료 분석 알고리즘의 정형화를 통해 제안 모델의 완전성을 검증한다.

Modern Joseon Architecture is North Korea's unique building style that interprets Korean traditional architecture in a modern way, and its most distinctive design feature is the Paljak roof that decorates the upper part of the buildings. This paper argues that continuous attempts at characterizing the nature of traditional Korean architecture in the late 1950s and early 1960s developed the theoretical rationale for the exclusive use of the Paljak roof in Modern Joseon Architecture. It also argues that the construction of the Pyongyang Grand Theater and the Okryu Restaurant during this period became a decisive moment for the formalization of the Paljak roof. The double roof rafters and gables and the "cheerful yet solemn" roofline were considered as main characteristic features of the Korean roof and the Paljak roof perfectly fits this description. Particularly, in North Korean society where Kim Il Sung became idolized as an impersonalized deity, an anecdote in which Kim Il Sung fixed a prominent gabled roof in the Pyongyang Grand Theater into a Paljak roof has allowed for the roof to gain an exclusive status. Hence, almost all Modern Joseon Architecture since the 1960s accepted the Paljak roof's monopoly position, rather than experimenting with other traditional roof types.

In recent times, an exponential increase in Internet traffic has been observed as a result of advancing development of the Internet of Things, mobile networks with sensors, and communication functions within various devices. Further, the COVID-19 pandemic has inevitably led to an explosion of social network traffic. Within this context, considerable attention has been drawn to research on network traffic analysis based on machine learning. In this paper, we design and develop a new machine learning framework for network traffic analysis whereby normal and abnormal traffic is distinguished from one another. To achieve this, we combine together well-known machine learning algorithms and network traffic analysis techniques. Using one of the most widely used datasets KDD CUP'99 in the Weka and Apache Spark environments, we compare and investigate results obtained from time series type analysis of various aspects including malicious codes, feature extraction, data formalization, network traffic measurement tool implementation. Experimental analysis showed that while both the logistic regression and the support vector machine algorithm were excellent for performance evaluation, among these, the logistic regression algorithm performs better. The quantitative analysis results of our proposed machine learning framework show that this approach is reliable and practical, and the performance of the proposed system and another paper is compared and analyzed. In addition, we determined that the framework developed in the Apache Spark environment exhibits a much faster processing speed in the Spark environment than in Weka as there are more datasets used to create and classify machine learning models.
