In this study, author suggests menu selection according to disease and standard cooking methods for hospital patients. Nutritional state of patients must be considered to select menu. Especially age, sex, and disease symptoms are important factors to determine the nutritional requirement. Special diet should be delivered to cure the patients with different appetite, digesting ability and symptoms. Menu must be planed including various food although nutritional restrictions should be considered, In this point of view, effective cooking methods and considerations of various Korean traditional food as hospital food are suggested. Recipe of traditional Korean beverage and cookies are also presented.

In this paper, we described the basic elements(flowability, fillingability, elapsed time, pumpability, no-vibrating effects, and etc.) required for the application and quality control of the super flowing concrete (SFC) in construction site. Also, after investigating characteristics of SFC through various experiments, SFC were placed in the reaction wall of large scale structural laboratory in Deawoo Insititute of Construction Technology. As the result of this project, the developed SFC showed high flowability and self-filingability good enough for the requirement. Furthermore, quality control and assurance of the no-vibrating concrete in actual site was verified by various testing.

Only do we have an earth! It is crucially important to improve our living environment and keep the sustained development of a city in the limited space. Some concrete examples will be analysized in the paper, elaborating upon how to make full use of roof space and various plants to create a better green-space. To create different activity space with unique characteristics for people, various plants, roof-space, water and buildings in the style of garden should be use when local conditions and design requirement should be considered.

For systematic and effective achievement of Military R&D(Research and Development) processes and activities, information system which supports the concept of Systems Engineering is necessary. WISEMAN(Weapon System Information Integration for System Engineering and Management) is an information integration system, which can provide various kinds of interrelated application functions and assist the collaboration and concurrent engineering activities for weapon system R&D processes and activities. WISEMAN can manage the design information and configuration data of the target development products. It takes charge of the processes and histories about the product data, makes to share all the design information, and provides important application functions for R&D processes such as requirement management, product structure management, parts Management, documents and CAD drawing management, design change management, TDP(Technical Data Package) management etc., and in conjunction with these functions WISEMAN controls various effectivities of system configurations based on baselines and model information. WISEMAN has been used by ADD and Rotem Co. since developed.

The construction industry consists of various and massive architectural information as an architectural process includes a variety of design stages with cooperation of many disciplines. Particularly, architectural information is generated and managed through the life cycle of a building, from conceptual design stage to the construction and maintenance. A Building Information Model (BIM) serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward. BIM technology accomplished quantitative development being utilized in various disciplines. However, it is necessary to develop environment and requirement for qualitative improvement of BIM based project. Particularly, requirement is very important for architectural design evaluations. The purpose of this study is to develop and apply of quality control check-list for improving the quality of architectural design in BIM environments. To achieve this purpose, the authors have investigated case study for open BIM data quality control (software, guideline and application case) and classified quality control targets according to physical/logical quality control and data quality. In addition, the authors have defined open BIM based quality control process and developed quality control check-list. Finally, the authors have developed automatic quality check system using requirements for efficient quality control based on open BIM.

Various linear system solvers with multi-physics analysis schemes are compared focusing on the near-field region considering thermal-hydraulic-chemical (THC) coupled multi-physics phenomena. APro, developed at KAERI for total system performance assessment (TSPA), performs a finite element analysis with COMSOL, for which the various combinations of linear system solvers and multi-physics analysis schemes should to be compared. The KBS-3 type disposal system proposed by Sweden is set as the target system and the near-field region, which accounts for most of the computational burden is considered. For comparison of numerical analysis methods, the computing time and memory requirement are the main concerns and thus the simulation time is set up to one year. With a single deposition hole problem, PARDISO and GMRES-SSOR are selected as representative direct and iterative solvers respectively. The performance of representative linear system solvers is then examined through a problem with an increasing number of deposition holes and the GMRES-SSOR solver with a segregated scheme shows the best performance with respect to the computing time and memory requirement. The results of the comparative analysis are expected to provide a good guideline to choose better numerical analysis methods for TSPA.

인공지능 기반 지능형 시스템의 개발에는 일반적으로 신뢰성 높은 대규모 지식처리, 지식의 통합과 인간 수준의 이해, 지식기반 인간-기계협업, 전문가 수준의 지능 서비스 등의 효과적 통합이 요구된다. 특히 빅데이터 이해 기반 자가학습형 지식베이스 및 추론 기술 개발을 목표로 하고 있는 과제의 일환으로 개발 중인 WiseKB 통합 플랫폼은 대용량 지식을 저장하여 추론과정을 통한 질의 및 응답이 가능한 대규모 지식 베이스 역할을 수행하며 이를 위하여 지식표현, 자원통합, 지식저장소, 지식베이스, 복합추론, 지식학습 등의 요소기술들의 효과적 통합이 필수적이다. 통합 플랫폼의 효율적 통합을 위해서는 정확한 요구사항 분석이 중요하며, 이는 시스템의 특성을 고려한 적절한 요구사항 분석 방법론의 적용이 필요하다. 대표적인 요구사항 분석 방법인 순차적 방법론과 순환-점진적 방법론은 WiseKB와 같은 시스템의 대규모 복합적 개발 특성을 고려할 때 다양한 요구사항을 체계적으로 파악하기에 한계가 있다. 본 논문에서는 이러한 한계를 개선하고자 순차적 방법과 순환-점진적 방법론을 결합해 각 단점을 보완하고 대규모 복합적 특성을 갖는 시스템의 요구사항 분석을 효율적으로 진행할 수 있는 통합 방법론을 제시하고, 실제 적용을 통해 그 효과를 보인다.
