대부분의 사용자 인터페이스 관리 시스템은 사용자 인터페이스의 대화 모델을 채 택하고 있다. 사용자 인터페이스 관리 시스템의 구현은 채택된 사용자 인터페이스의 대화 모델에 의해 강한 영향을 받는다. 모델-뷰-콘트롤러(Model-View-Controller : MVC) 프레임웨이 Smalltalk 환경에서 사용자 인터페이스 개발의 여러 측면에서 기여한 동안 사용자 인터페이스는 강하게 결합된 모델, 뷰, 콘트롤러 클래스를 가진 MVC를 이 용하여 생성되었다. 이러한 결합은 소프트웨어 부품의 재사용을 방해하였다. 따라서 본 논문에서는 MVC모델이 갖는 강한 결합력으로 인한 소프트웨어 재사용의 저하를 해 결하기 위해, 상호 작용의 구문적 관리를 하는 다이알로그 객체를 추가하여 사용자로 부터 생성된 메세지가 콘트롤러에 의해 바로 값이 변경되지 않고 다이알로그에 전달 되도록 MVCD모델을 제안하였다. 메세지를 전달받은 다이알로그 객체는 모델 객체의 값 을 변경하기 위해 모델 객체를 호출한다. 모델 객체는 active 값들을 가지고 있기 때 문에 값의 변경은 연결된 콘크롤러 객체에게 전달된다. 최종적으로 콘트롤러 객체는 새로운 값을 변경하고 뷰 객체를 수정한다. 이러한 사용자 대화 모델에 기반을 둔 사 용자 인터페이스 구축기를 X-윈도우상에서 OSF/Motif을 이용하여 개발하였다. Most UIMS(User Interface Management System) adopt dialogue model of user interface Implementation of UIMS influenced by adopted dialogue model of user interface strongly. While the Model-View-Controller framework has contributed to many aspects of user interface development in Smalltalk environment- user interfaces generated with MVC have highly coupled model, view, and controller classes. Such coupling impedes the reuse of software component. So In this paper, we suggest MVCD model to resolve a decline of reuse with MVC have highly coupled. User messages are not changed by Controller immediately, but sent to Dialogue object which maintains the syntatic structure of the interaction. Dialogue object invokes Model object to updates is value. Since Model objects have active values, the value change propagates to the linked Controllers. Finally, Controller object convert the new value and update the View object. User interface builder is implemented on X-window with OSF/Motif that is base on this user dialogue model.

금융권 공동 오픈 플랫폼 구축·서비스에 따라 스타트업 생태계에 안전한 보안 기술이 요구되고 있다. 금융권 표준 오픈 API는 상호인증 과정의 핵심 API 인증키 보호를 위해, 결제 관련 핀테크 기업이 추가 보안 기술을 개발/적용하는 것을 권고하고 있다. 본 연구는 다중 채널을 사용하는 강화된 API 보안 프로토콜을 제안한다. 기존 오픈 API 관련 연구의 문제점과 취약점을 추가 분석하고, 이기종 플랫폼의 호환성을 고려하여 설계되었다. 기존 보안 프로토콜의 단일 채널에 추가 보안 채널을 분리하여 은닉하는 방법을 적용했다. 성능 분석 결과 다중 채널의 통신 세션 양방향 안전성과 강화된 인증키의 중간자 공격 안전성을 확인하였으며, 다중 세션에서 지연시간의 연산 성능(1초 이하)을 확인하였다. Safe security technology is required for the startup ecosystem according to the construction and service of a joint open platform in the financial sector. Financial industry standard open API recommends that payment-related fintech companies develop/apply additional security technologies to protect core API authentication keys in the mutual authentication process. This study proposes an enhanced API security protocol using multiple channels. It was designed in consideration of the compatibility of heterogeneous platforms by further analyzing the problems and weaknesses of existing open API related research. I applied the method of concealment to remove the additional security channels into a single channel of the existing security protocols. As a result of the performance analysis, the two-way safety of the communication session of the multi-channel and the security of the man-in-the-middle attack of the enhanced authentication key were confirmed, and the computational performance of the delay time (less than 1 second) in the multi-session was confirmed.

A study presents the problem from performing the experiment of both survey and analysis on the color distribution of Jeju at first, including L*a*b color diferences and color harmony. It has been found that the color distributions of buildings at four districts in Jeju are summarized as follows. (1) The hues of warm colors, R, YR, Y, and GY, distribute mainly on the building exterior performed in the survey of 4 districts, and low chroma in 1.0-20 are prevailed. (2) The color distributions of the districts are included in the terms of disharmony from the results of adaption to the principle of modifying color harmony. (3) By the results of analysis on color image using L*a*b* color diferences, it is noticed that most buildings stand at random without the consideration of color harmony between next attached buildings. From the survey, it is recommanded to rehabitalize the color image of building exterior in the city, and in consequence, more obstinate code formats of new building exterior standing in lines on the main street, Jung-Ang, must be considered to satisfy color accordance.

This study is based on the fact that there are no studies suggest concrete decision factors regardless of many changes in investment decision factors that investors think after the amendment of the Lending Law. With the three purposes, the study is to analyze the significance of investment factors that investors must consider when deciding on NPLs. With the three purposes, the study is to analyze the significance of investment factors that investors must consider when deciding on NPLs. The methodology of this study can be divided into two. First, in order to analyze the effect of actual NPL auction on the winning bid price, the value of the unsecured bond was designated as a dependent variable and area, use area, and the number of miscarriage as the independent variable, so the multiple regression analysis was conducted to determine the winning bid price. Second, a survey was conducted to determine the impact of the decision on investment in NPLs. The effect of NPLs on the investment recommendation was analyzed and, as a result of verification of the hypothesis that investment environment, property, investment corporation, NPL property, and investment method will affect investment recommendation, the result showed that NPL property, and investment method influenced the investment recommendation. In the analysis of the impact of the investment recommendation on the investment intention, the investment intention affects the investment recommendation of others positively, that the research hypothesis can be adopted.

As a new interpretation of the space in modem times which was caused by the Brancusi`s discovery of the primitive sculpture in early 20 century was started, the abstract movement of the sculpture and the variation of the location in sculpture were started. Seperated from closed space, and going through combining with natural space, and combining with architecture in urban space. Sculpture, together architecture, occupied a great part of the artificial surroundings to modern times, and became an important essential element which purified the man`s mental world, as in all art divisions. The reason that sculpture became an essential constituent unit of the urban surroundings like this, dues not only to the beauty that sculpture itself emanates, but all so the summary of a certain place characteristics, and to the rearrangement of the discursive circumference. The formative surroundings which this thesis aims at not set limites to sculptor only, but includes allround art meaning. Therefore, restricting of the breadth much more with the messes by means of close interchange relations with various art fields, such as architecture, City plan, music, and literature, is the great task. Surroundings are not dependent on by whom it was composed, and by what intention it was composed. By whomever it was made, by what intention it was started, it is recognized as surrounding, I say, by real relationships with present men. Modern sculpture must leave the closed space of the museum or art gallery, and be with the masses in public square, and discharge its duties as a new nature in city space where the nature die a way. It must take not only the constant the nature die a way. It must take not only the constant effort of the artist himself and the inevitable of all arts, but also the rigorous cooperation which material, administrative situations support actively.
