Medical information system based on ad hoc network designed for general information systems and information networks have different security requirements. Malicious code infiltration and security features are performed on same medical information network architecture along the route. Security domain of medical information systems is the ground of penetration and defense performed over the network architecture and it is also the traffic handling areas separated by a concept of differentiated group. Ad hoc-based medical information systems in the network security domain, set some standards about what should be the methodology of this study. In this paper, medical information system network configuration, the determining factor based on the security domain, the structure selection criteria and blocking positionings are presented according to the traffic route configuration. If you apply this methodology designed to increase security, efficiency can be possible. Health information systems in accordance with the security domain areas requires differentiated protection needs of the security mechanism that is proposed by this study.

The importance of modeling in large-scale software development has already been confirmed. In most of the projects, modeling is done using UML. However, UML is a class-based modeling tool, which is complicated and lacks in modeling common modules, components, processes, and data. To supplement this point, this paper will help the actual industrial field by suggesting the integration of various modeling techniques, including structural methodology and information engineering methodology developed in the computer field. Through this paper, I would like to show that it is useful to use various methodologies instead of using UML to develop software that satisfies customers.

우리나라 주거양식의 근대화는 단순히 전통한옥에서 현대의 주택, 아파트로의 교체가 아니라 일련의 연속적인 변화과정 속에서 시대를 살아온 사람들의 생활양식과 문화를 담고 있다고 볼 수 있다. '주택이란 삶을 담는 그릇'이라는 표현에서 볼 수 있듯이 주택이란 거주자의 가치관을 포함한 주생활양식과의 대응 속에서 주거환경의 질적 향상이 이루어질 수 있다. 따라서 주거양식의 변화에 관한 연구 또한 이러한 삶과 문화에 대응하는 방향으로 이루어져야 바람직할 것이다. 이상의 배경 하에 과거 전통주택에서부터 근대화 이후의 여러 주택유형에 이르기까지 다양한 유형을 포함한 우리 나라 주택이 가지는 공간구조의 변천을 시대적으로 조망하고자 하였다. 이를 위하여, 전통사회의 양반주택, 도시형한옥, 표준주택, 일반단독주택, 작가주택, 아파트에 이르는 다양한 주택유형을 포함하여 총 104개의 주택평면을 대상으로 공간구조의 변화에 대한 분석을 실시하였다. 또한 다양한 주택유형들이 보여주는 공간구조와 그 통시적 변화를 객관적이고 계량적인 방법론을 이용하여 관찰하고자 공간구문론의 분석방법을 이용하여 주택형식에 따른 기능적 형상학을 뛰어넘는 사회학적 형태학의 관점에서 우리나라 주거의 변천과정을 고찰하고자 한다. 상기한 바와 같이 개개의 주택형식에 대한 고려보다는 시대적 상황과 배경을 설명해주는데 용이한 대상을 중심으로 전반적인 변화의 양상과 그러한 변화에 내재한 사회적 동인과 배경을 파악하고 이해하고자 하였다.

LLRP (Low-Level Reader Protocol) specifies an interface between RFID readers and RFID applications, also called LLRP servers and clients respectively. An LLRP server should concurrently execute various functions. This paper designs an LLRP server of a multi-threaded architecture. For that, (i) the operational procedure between LLRP servers and clients is investigated, (ii) the functional requirements of LLRP servers are presented, (iii) the operation of an LLRP server is decomposed into several threads to satisfy those functional requirements, and (iv) the operational procedure is further examined in thread-level. To validate the designed architecture, it is modeled and simulated by using the DEVS formalism which specifies discrete event systems in a hierarchical, modular manner. From the simulation result, we can conclude that the proposed architecture conforms the LLRP standard and satisfies all the given functional requirements.

In this paper, we propose a new code acquisition architecture having the features of low complexity and high speed for the MC-CDMA system. The newly designed searching finger has function of the searcher as well as the finger. The searching finger tests the PN code Phase as the searcher during the initial acquisition, and as the finger after the initial acquisition. The proposed system has reduced the average acquisition time of the PN codes to $T_{acq}$/19 in the 20MHz MC-CDMA system with 75% reduction of H/W complexity.y.

Specifying the semantic structure for functional interfaces and lambda expressions, which are the latest features of Java, can be referenced when designing similar functions in the future, and is also required in the process of standardizing or implementing an optimized translator. In this study, action equation 3.0 is newly proposed to express the static and dynamic semantic structure of functional interfaces and lambda expressions by modifying and upgrading the existing expressions to express the semantic structures of java functional interfaces and lambda expressions. Measure the execution time of java programs by implementing the semantic structure specified in action equation 3.0 in java, and prove that action equation 3.0 is a real semantic structure that can be implemented through simulation. The superiority of this action equation 3.0 is to be confirmed by comparing the action equation 3.0 specified in the four areas of readability, modularity, extensibility and flexibility with the existing representative semantic expression methods.

In this study, a tsunami fragility methodology was determined for a probabilistic safety assessment(PSA) induced tsunami event in Nuclear Power Plant(NPP) site. For this purpose, a fragility evaluation method was presented using previous external PSA method. Failure mode and failure criteria about major safety related equipments and structures were determined. Finally, a tsunami fragility assessment was performed for offsite transformer in NPP site. For the fragility evaluation, structural failure like overturning and sliding and functional failure induced by inundation. Through this study, it can be concluded that a functional failure according to inundation height was governed total probability of failure of offsite transformer in NPP.

A new mechanical heart valve prosthesis has been designed appling systematic design methodology. The function of the heart valve was defined, and search for design variation has been carried out according to the functional structure, Optimal model among the various variations was determined in view of the design specificationn. Proto type valve was fabricated and test has been carried out using a mock circulation system. It has been observed that the pressure profile, cardiac output and behavior characteristics are generally satisfactory.
