Nowadays, new product development (NPD) is one of the most crucial factors for business success. The manufacturing firms cannot afford the resources in the long development cycle and the costly redesigns. Good product planning is crucial to ensure the success of NPD, while the Quality Function deployment (QFD) is an effective tool to help the decision makers to determine appropriate product specifications in the product planning stage. Traditionally, in the QFD, the product specifications are determined by a rather subjective evaluation, which is based on the knowledge and experience of the decision makers. In this paper, the traditional QFD methodology is firstly reviewed. An improved Hybrid Quality Function Deployment (HQFD) [MSOfficel] then presented to tackle the shortcomings of traditional QFD methodologies in determining the engineering characteristics. A structured questionnaire to collect and analyze the customer requirements, a methodology to establish a QFD record base and effective case retrieval, and a model to more objectively determine the target values of engineering characteristics are also described.

This study attempted to classify the types of perceptions of the new Hanbok, focusing on female college students in their 20s, and to analyze the characteristics of each type. This study was conducted with the Q methodology and analyzed with the QUANL pc program. The perceptions of the new Hanbok among female college students in their 20s were classified into four types: Type 1: modern/practical, Type 2: convenient/practical, Type 3: temporary/accessible, and Type 4: convenient/traditional. Type 1 emphasized the selection of Western clothing fabric, matching zipper/buttons, and achromatic colors. Type 2 highlighted a design that can be worn as daily clothing by combining materials that are convenient for laundering. Type 3 stressed the operation of new Hanbok rental stores so that it is easy to access and accept new Hanboks in old palaces and Hanok villages. Type 4 required the development of a design that reflects the elements of the traditional Hanbok and is convenient for activity and laundering.

This study used the Q-methodology to identify and categorize the types of subjective perceptions of Korean hanbok among foreigners currently living in Korea, and to explore the characteristics of each type. We used the QUANL PC program to analyze the data. We categorized foreigners' perceptions of hanbok into three types. The first type comprised the "hanbok experience novice tradition affirming" individuals who thought hanbok was beautiful, affirming Korean culture and traditional clothing. They encountered hanbok for the first time upon arriving in Korea. The second type was the "design preference positive change". These individuals thought hanbok's design was beautiful and belived Korea's image improved because of hanbok. The third type was the "change-seeking tradition negative". This group believed that hanbok was not traditional Korean clothing and required modernizing. The first category comprised mostly individuals from Nepal, the second category was Myanmar, and the third category was China. Thus, different nationalities have different perceptions of hanbok. Future research should explore how foreigners from diverse nationalities perceive hanbok and coduct a comparative analysis based on nationality.

Field programmable gate array (FPGA)-based systems are thought to be a practical option to replace certain obsolete instrumentation and control systems in nuclear power plants. An FPGA is a type of integrated circuit, which is programmed after being manufactured. FPGAs have some advantages over other electronic technologies, such as analog circuits, microprocessors, and Programmable Logic Controllers (PLCs), for nuclear instrumentation and control, and safety system applications. However, safety-related issues for FPGA-based systems remain to be verified. Owing to this, modeling FPGA-based systems for safety assessment has now become an important point of research. One potential methodology is the dynamic flowgraph methodology (DFM). It has been used for modeling software/hardware interactions in modern control systems. In this paper, FPGA logic was analyzed using DFM. Four aspects of FPGAs are investigated: the "IEEE 1164 standard," registers (D flip-flops), configurable logic blocks, and an FPGA-based signal compensator. The ModelSim simulations confirmed that DFM was able to accurately model those four FPGA properties, proving that DFM has the potential to be used in the modeling of FPGA-based systems. Furthermore, advantages of DFM over traditional reliability analysis methods and FPGA simulators are presented, along with a discussion of potential issues with using DFM for FPGA-based system modeling.

본 논문에서는 프로그램의 성능을 향상시키기 위하여 프로그래머들이 다른 성능조율 대안들을 평가하는 것을 돕는 새로운 평가 방법론을 소개한다. 이 방법론은 조율 대안이 채택된 경우의 성능을 평가할 수 있게 한다. 구체적으로 말하자면, 성능 병목 지점의 확인을 위하여 프로그램 구성 요소들에서 소요되는 시간을 수량화하는 전통적인 성능 평가 방법론과는 대조적으로 분산 또는 병렬 프로그램이 처리하는 일의 이동 이후의 성능을 예측한다. 따라서, 이 방법론은 일의 처리 장소를 변경함으로써 성능을 향상시키는 것에 대한 가이드라인을 제공한다. 이 방법론을 사용하면 기반 네트워크 변경에 따른 성능에 대한 파급효과도 예측할 수 있다. 이 방법론은 조율할 프로그램이 실행되는 동안 점진적으로 그리고 온라인으로 성능을 평가할 수 있다. 본 논문에서는 이 방법론을 구현한 후 사용했을 때 여섯 프로그램들의 검사 집합에 대하여 다른 조율 대안들의 성능을 정확히 예측할 수 있다는 실험 검증 결과를 보인다.

The KAMYOUNG is the supreme local government office in CHOSEON dynasty. This study aims to propose the new methodology on research of local government office's prototype in CHOSEON dynasty. Especially this study is the zoning plan of the KAMYOUNG in the late CHOSEON dynasty, It is meant to present the first trial that pursue to total frame of local government in CHOSEON dynasty through the new methodology. The 18th century is the transitional era when the system of norm was deconstructed. The institution and organization of the supreme lacal government office(KAMYOUNG) was united nationwidely and at the same time its deconstruction was carried out in the 18th century. The domain of the governer has fixed in the 18th century, though the scale of 街e KAMYOUNG was enlarged. These domain expressed a strong symbolization according to hierarchy in exterior appearance of the traditional architecture. With the entire execution of a local government coming soon, the concerns about the localization have been increased rapidly. Under this time situation, as the discussion centered on the creation or change of the local self-governing community, so the concerns regarding the traditional aspects of a local government office have been increasing. Hower, without the recognition of this history, as the research of these existing historical materials has been progressed, so the misunderstanding is still left. Especially, because the government office of CHOSEON is a Confucian nation thinking much of a hierarchy based on Yae - Jae, the hierarchy of this architecture has a deep correlation with the organization of an office. The method of this study is like following: Firstly, prescribed characteristic of KAMYOUNG tough syudys of hierarchy in a local government system, human and material composition. secondly, as the changing progress of KAMYOUNG is compared and analyzed with organization of an office in the center. So characteristics of KAMYOUNG are abstracted. And finally, from this, the interpretation methodology of KAMYOUNG is revealed, with a deep correlation between specific characters of organization and architectural structurals. And also, with these methodologies, the interpretation method of the local government office and normative frame in CHOSEON dynasty are suggested.
