[ $\circ$ ] Enterprise architecture is essential for ROI of e-Enterprise. $\circ$ An architecture is described from business, application, data and technical views and these must be complete and consistent. $\circ$ UML-based CBD is currently the best approach to obtaining architecture-centric, flexible and interoperable systems. $\circt$ Reuse of architecture, components, shared services and app frameworks is key to achieving both quality and productivity. $\circ$ Web service, the NBT, cannot be tapped without the architecting capability. $\circ$ Architects with world-class domain as well as software engineering knowledge are key to success of Korean software industry.

본 논문에서는 TV 브라운관 유리용해로의 온도 제어를 위한 고전 고급 제어 (Conventional Advanced Control) 알고리듬을 제시한다. 용해로의 특성에 맞도록 중요한 입출력 변수를 선정한 후, 공정 실험을 통하여 얻어진 데이터를 바탕으로 입출력 변수들간의 초보적인 FOPDT (First Order Plus Dead Time) 모델들의 조합으로 용해로를 모델링하였다. 수립된 모델을 바탕으로 주요 입출력을 PI (Proportional - Integral) 형태의 cascade 및 단일 궤환 루프(Single feedback loop)들의 조합으로 제어기를 구성하였다. 제시된 알고리듬은 기존 용해로에 설치되어 있는 DCS를 이용하여 구현되었고, 일 150톤 생산 규모의 용해로에 성공적으로 실적용되었다.

This study presents the core contents and superiority of localized Point-Machine which Alstom transferred its technology to Samsung SDS for High Speed Rail, developed based on existing MJ8l Point-Machine that is used in France and other countries. The scope of study includes introducing performance improvement of Localized MJ8l and conducting comparative analysis between Localized MJ8l and french products as well as NS type Point-Machine that has been deployed in the existing rail link. Moreover, the general architecture, features and test run results of Localized MJ8l are described.

본 논문에서는 용해공정을 위한 실시간 퍼지 전문가 시스템을 소개한다. 유리 용해 공정은 운전자의 경험지식에 의해 내부의 상황을 판단하게되고, 이는 용해로 수명과 제품의 품질에 중요한 영향을 준다. 기존 운전자의 지식을 분석하여 룰을 형성하고, 시스템에 맞도록 구현한 방법을 제시한다. 제시된 퍼지 전문가 시스템은 실제 용해로의 생산공정에 효율적으로 적용되었다.

We give secure parameter suggestions to use sparse secret vectors in LWE based encryption schemes. This should replace existing security parameters, because homomorphic encryption (HE) schemes use quite different variables from the existing parameters. In particular, HE schemes using sparse secrets should be supported by experimental analysis, here we summarize existing attacks to be considered and security levels for each attacks. Based on the analysis and experiments, we compute optimal scaling factors for CKKS.

국내 가전업체 경쟁 심화에 따라 물류 품질 등 비가격 경쟁력이 점차 중요해지고 있다. 특히 고객의 수/배송 및 배달설치 만족도 관련 요구 증가와 물류 운임 상승 등은 고도화된 물류 대응 역량을 기업에게 요구하고 있다. 따라서 기업들도 기본적인 업무처리 중심의 물류 운영에서 기능이 고도화된 물류 체계 및 시스템의 도입을 위한 혁신을 진행하고 있다. 본 논문에서는 이러한 물류업무 혁신의 일환으로 진행된 물류 거점 간 최적운송 체계 도입과 고객을 대상으로 제품 구매 시점에 배달/설치 가능한 정확한 납기약속을 제시할 수 있는 납기약속 체계를 도입한 사례를 소개하고자 한다. 특히 물류 현장에 새로운 개념을 도입/적용하는 과정에서 발생할 수 있는 이슈에 중점을 두어 살펴 봄으로써 유사한 프로세스 흑은 시스템을 도입할 때 시행착오를 최소화하여 조기 안정화에 도움을 주고자 한다.

Asian populations contain a variety of ethnic groups that have ethnically specific genetic differences. Ethnic variants may be highly relevant in disease and human differentiation studies. Here, we identified ethnically specific variants and then investigated their distribution across Asian ethnic groups. We obtained 58,960 Pan-Asian single nucleotide polymorphisms of 1,953 individuals from 72 ethnic groups of 11 Asian countries. We selected 9,306 ethnic variant single nucleotide polymorphisms (ESNPs) and 5,167 ethnic variant copy number polymorphisms (ECNPs) using the nearest shrunken centroid method. We analyzed ESNPs and ECNPs in 3 hierarchical levels: superpopulation, subpopulation, and ethnic population. We also identified ESNP- and ECNP-related genes and their features. This study represents the first attempt to identify Asian ESNP and ECNP markers, which can be used to identify genetic differences and predict disease susceptibility and drug effectiveness in Asian ethnic populations.

There are many studies on the project planning, project management and quality management. The cost of the new project takes only 20% of system's lifetime resource and the costs of the maintenance and infrastructure take more than 80%, so the study on the maintenance is much more important than the study on the new project. There has been many studies on the economic life cycle of the system using it's maintenance cost, but no studies on it's infrastructure cost. This paper provides how we can adapt infrastructure cost, which takes more than 40% of system's life cycle cost, to the economic life cycle of the system and its effects on the system's economic life cycle.

In recent years, domestic electronics, banking, electricity, services, manufacturing, pharmaceutical, corporate type and malicious hackers is corporate security through the accident occurred and the resulting loss of corporate information and the damage each year is steadily increasing. Many companies have responded to domestic business activities and to protect critical information related to laptops, smart phones, tablets, and introduced a variety of Endpoint security solutions within. However, being introduced to senselessly Endpoint security solution across the over-budget, with the same features and performance, such as conflicts and problems arise, resulting in additional maintenance costs, in an effort to resolve the conflict in the operational security of the IT department's new difficulty in becoming. Here is the introduction and operation of these Endpoint security solutions in order to solve the problem on employees's PC into the center of the information security governance based on Endpoint security solution to provide the process for determining the solutions presented.

Recent deep learning-based research shows excellent performance in most natural language processing (NLP) fields with pre-trained language models. In particular, the auto-encoder-based language model proves its excellent performance and usefulness in various fields of Korean language understanding. However, the decoder-based Korean generative model even suffers from generating simple sentences. Also, there is few detailed research and data for the field of conversation where generative models are most commonly utilized. Therefore, this paper constructs multi-turn dialogue data for a Korean generative model. In addition, we compare and analyze the performance by improving the dialogue ability of the generative model through transfer learning. In addition, we propose a method of supplementing the insufficient dialogue generation ability of the model by extracting recommended response candidates from external knowledge information through a retrival model.
