In Korea, it raised the need of the specification of unit modular construction, because there are no standard or manual. And it is urgent that the specification of unit modular construction is needed to develop in the domestic. Therefore, this study aims to propose the manual framework of the construction method. In the future, this framework will be based on the development of the manual on the unit modular construction method.

New modular factory-built methodologies implemented in the construction and industrial plant industries may bring down costs for modular reactors. A factory-built environment brings about benefits such as; improved equipment, tools, quality, shift patterns, training, continuous improvement learning, environmental control, standardisation, parallel working, the use of commercial off shelf equipment and much of the commissioning can be completed before leaving the factory. All these benefits combine to reduce build schedules, increase certainty, reduce risk and make financing easier and cheaper.Currently, the construction and industrial chemical plant industries have implemented successful modular design and construction techniques. Therefore, the objectives of this paper are to understand and analyse the state of the art research in these industries through a systematic literature review. The research can then be assessed and applied to modular reactors.The literature review highlighted analysis methods that may prove to be useful. These include; modularisation decision tools, stakeholder analysis, schedule, supply chain, logistics, module design tools and construction site planning. Applicable research was highlighted for further work exploration for designers to assess, develop and efficiently design their modular reactors.

항공기에 탑재되는 레이다는 연속적으로 I/Q 데이터를 획득하는 동안 주어진 시간 내에 신호처리를 완료하는 실시간성을 반드시 유지해야 하며, 공대공부터 공대지, 공대해, Ground Map까지 다양한 모드와 기능을 수행해야 하는 특징을 가지고 있다. 따라서 개발이 진행될수록 레이다 신호처리 SW를 구성하는 코드의 구조가 복잡해진다. 또한 여러 모드를 순차적으로 구현하는 과정에서 기존 코드를 재활용하기도 하고 신호처리 알고리즘의 일부분만 바뀌기도 한다. 이와 같은 이유로 실시간성을 유지하며 코드의 재사용과 부분 교체가 편리한 모듈화의 장점을 이용해야 할 필요가 있다. 본 논문에서는 공대지/해를 구성하는 모드의 신호처리 과정을 통해, 실시간성을 유지하며 항공기 레이다 신호처리 SW에 적용 가능한 모듈화 Framework의 설계 방안을 제시한다.

Recent research has been ongoing for modular buildings in the country, and interest increases. However, in accordance with legal restrictions in the country with regard to Project Delivery system of Modular Building, the activation of modular buildings industry is obstructed. In Korea, in accordance with national contract law, the construction contract is apply to the project delivery system of modular buildings, and in accordance with Framework Act on the Construction Industry, The project delivery system of modular buildings has to be a separate order. The definition of separate order in contract as defined in the law is that the electric work and Communication work and digestion facility work has to be separate each contract in order to be ensured professionalism. In accordance with law, the project delivery system of modular buildings is that the contract for construction is concluded with the Owner and the Construction Contractor and the contract for goods is concluded with the construction Contractor and modular manufacturer. Due to these project delivery system, the domestic factory production rate when making a modular unit is significantly reduced compared to the rate of factory production abroad and the domestic factory production rate is estimated to 10-20%. Due to the factory production rate is also low, despite what can be done at the factory the workload in construction field increases. According to the workload in field increases, the effect of the schedule reduction can be reduced. It resolved to form a consortium with a modular manufacturer and construction companies or the contract is concluded with Owner, modular manufacturer and construction companies in each. In this paper, we propose a specific project delivery system for modular building to solve the problem of the low factory production rate and the problem of schedule reduction. Through this paper, due to the variety of project delivery system on modular buildings is expected to contribute to the activation of modular buildings.

Recently, high-rise building projects have been in the spotlight in South Korea. Curtain wall construction, as one of important operations in the high-rise building projects is composed of various, entangled and complex unit processes that require a systematic planning to prevent unexpected delays. A schedule simulation technique has been used for deriving more efficient planning and accurate performance measurement. However, the simulation technique has difficulty in collecting actual data and in applying data fluctuations during construction. Thus, this paper suggests a concept model of Modular Simulation Model(MSM) that overcomes such limitations of traditional simulation technique based on curtain wall operations.

A modular multidisciplinary analysis and optimization framework has been built with the goal of performing conceptual design of an advanced efficient supersonic air vehicle. This paper addresses the specific challenge of designing this type of aircraft for a long range, supersonic cruise mission with a payload release. The framework includes all the disciplines expected for multidisciplinary supersonic aircraft design, although it also includes disciplines specifically required by an advanced aircraft that is tailless and has embedded engines. Several disciplines have been developed at multifidelity levels. The framework can be readily adapted to the conceptual design of other supersonic aircraft. Favorable results obtained from running the analysis framework for a B-58 supersonic bomber test case are presented as a validation of the methods employed.

Weapon effect is a key issue throughout the life cycle of weapon systems. Only when weapon effect is considered properly, Effects Based Operation(EBO), Effects Based Acquisition(EBA), and Effects Based Development(EBD) could be possible. Because the transfer of weapon effect technologies is restricted in most foreign counties, independent development is necessary. In this paper, framework of weapon effects calculator for hardened targets is proposed to meet the own development needs. It is designed focusing on running time, validation and expandibility by adoption of modular architecture. Required technologies for each module are identified, and unclassified ones are summarized.

모듈러 공법은 건설 산업 경쟁력 강화를 위한 하나의 방안으로 주목받고 있다. 최근 핵가족화로 인한 소형주택의 수요 증가, 건식공법으로 변화되는 건설 산업 환경, 친환경 건설에 대한 요구 등에 따라 모듈러 공법 시장은 큰 성장세가 기대되고 있다. 하지만 아직 모듈러 업체들이 표준화되지 않은 내역체계로 공사를 수행하고 있어 공사비에 대한 리스크가 증가될 우려가 있다. 따라서 본 논문에서는 모듈러 공법의 특징과 프로세스가 반영된 내역체계를 개발하고자 하였다. 이를 위해 우선 모듈러 공법, WBS, CBS의 개념 정리 및 일반 RC공사에 쓰이는 표준 내역서를 분석하고 모듈러 공법이 적용된 사례 분석과 전문가 인터뷰를 통해 모듈러 공법 내역체계에 적합한 작성기준들을 선정하였다. 한편 모듈러 공법은 공장생산 비율이 높기 때문에 프로젝트 흐름을 반영하여 모듈러 공장제작, 모듈러 현장시공, 일반 현장시공으로 체계를 크게 구분하였으며 각 내역 항목들 중에서도 모든 현장에 공통으로 적용이 가능한지 아닌지, 규격 변경 또는 내역 삭제가 가능한지 아닌지 등을 표시하였고 마지막으로 숫자로 구성된 코딩을 넣음으로써 모듈러 공법의 특징이 반영된 내역서를 개발하였다. 이는 모듈러 공법 공사비 예측 정확도를 높여 공사비에 대한 리스크를 절감시키고, 더 나아가 모듈러 공법 활성화에 기여할거라 기대된다.

This paper introduces DICE, a Domain-Independent text Classification Engine. DICE is robust, efficient, and domain-independent in terms of software and architecture. Each module of the system is clearly modularized and encapsulated for extensibility. The clear modular architecture allows for simple and continuous verification and facilitates changes in multiple cycles, even after its major development period is complete. Those who want to make use of DICE can easily implement their ideas on this test bed and optimize it for a particular domain by simply adjusting the configuration file. Unlike other publically available tool kits or development environments targeted at general purpose classification models, DICE specializes in text classification with a number of useful functions specific to it. This paper focuses on the ways to locate the optimal states of a practical text classification framework by using various adaptation methods provided by the system such as feature selection, lemmatization, and classification models.
