본 논문은 QFD(Quality Function Development)기법을 활용하여 소비자의 요구사항을 반영한 음식물 처리기의 핵심 품질 요소를 도출하는데 목적을 두었다. 일반 소비자와 관련업계 종사자를 대상으로 설문조사와 FGI를 실시하여 VOC(voice of customer)를 도출하였고, 전문가 그룹을 통해 EC를 도출하여 VOC와 EC(Engineering Characteristic)간의 상관관계를 도표화 하여 HOQ(House Of Quality)를 작성하였다. HOQ 차트를 통해 분쇄건조식 음식물 처리기에 있어 우선시 되는 것은 음식물 분쇄기능, 건조기능 외에 냄새 배출기능, 외관 색상 등의 요소가 중요한 품질요인이라는 결과을 도출하였다. 부품별 요인으로는 분쇄 탈수와 관련 된 모터와 냄새 제거와 관련한 팬모터가 가장 핵심 부품으로 고려되어야 한다는 결과를 도출하였다.

가스센서는 인간의 오감 중에 후각 기능을 대신하는 것으로 사회 여러 분야에 응용범위가 확대되고 있다. 유기화합물(VOC; volatile organic compounds) 가스는 대기환경을 오염시켜 스모그를 발생하며 인체에 발암을 유발하는 물질이기 때문에 많은 문제와 규제가 예상되고 있다. 따라서 VOC를 감지하고 정확히 분석할 수 있는 환경 측정용 센서에 대한 요구가 절실해지고 있다. 최근에는 고온에서 동작하는 산화물 반도체 센서와는 달리 상온에서 유해성 가스를 감지할 수 있는 전도성 고분자의 특성이 알려지면서 센서 물질로 각광을 받고 있으며, 특히 유해성 가스인 VOC 가스를 검지 할 수 있는 센서로서 주목을 받고 있다. 전도성 고분자인 Polypyrrole를 pyrrole monomer, APS, DBSA를 사용하여 $0^{\circ}C$, 1기압에서 화학중합을 하였다. 만들어진 powder를 chloroform과 DBSA를 사용하여 용액을 만들어 전극에 dipping하고 7$0^{\circ}C$, 질소 분위기에서 1시간동안 건조를 하고 methanol에서 1시간동안 soaking 처리를 한 뒤 7$0^{\circ}C$, 질소 분위기에서 4시간동안 열처리 과정을 통해 센서를 제조하였다.

The purpose of this study is to explore the applicability of QFD to product development of clothes by empirically applying it to development of a specific clothes, middle and elderly women’s formal knitwear. The voices of customers(VOCs) for formal knitwear was collected through in-depth interviews with 25 customers, shop masters, and designers. Also, questionnaires of which respondents were 230 customers were used to rank the importance of the items of VOC. A QFD team of 10 knitwear experts implemented the task of translating VOCs into design attributes and measuring the values of the relationships between VOCs and design attributes. Importance ranking of the items of design attributes was obtained based on Lyman's method. The results of this study were as follows. First, the customer requirements for formal knitwear were classified into five dimensions, that is, symbolism, aesthetic, fitness, usefulness, and maintenance. Second, the descending order of the necessity of improving the quality was maintenance, aesthetic, fitness, usefulness, and symbolism. Third, three-staged design attributes were obtained as a result of translating of VOCs into design attributes. Lastly, the descending order of the importance of design attributes was "sorts of yarn", "sorts of color jacquard", "color", "tone", "ease", etc.

We developed an integrative annotation program that can perform data labeling process for deep learning models in object recognition. The program utilizes the basic GUI library of Python and configures crawler functions that allow data collection in real time. Retinanet was used to implement an automatic annotation function. In addition, different data labeling formats for Pascal-VOC, YOLO and Retinanet were generated. Through the experiment of the proposed method, a domestic vehicle image dataset was built, and it is applied to Retinanet and YOLO as the training and test set. The proposed system classified the vehicle model with the accuracy of about 94%.

This paper proposes an effective method on the DFILS(Design for Integrated Logistics Support) in ammunition development applying QFD(Quality Function Deployment) method. The goal of this research is to define the Design for ILS approach at the start of the ammunition development and to yield a set of reusable requirements. Based on 000mm High-Explosive(Warship ammunition) development work, a QFD software tool, CUPID, was used to analyze and define the field force's requirements. Additionally, a set of reusable requirements are identified and defined for use during the Design for ILS development phase in the next-generation ammunition development process. These set of requirements that consider both the priority and importance of the VOC(Voice of Customer) will contribute to the early phase of the ammunition development to implement the Design for ILS specialty engineering effort.

The thesaurus can control the headings in a classification scheme and can serve as an index of the classification scheme itself. In records management, the thesaurus controls functional terms and expands the access point of search to complement the functional classification scheme. In recent years, ISO 25964, the international standard for thesaurus construction, has been revised because of changes in the information environment and the development of thesaurus construction and utilization systems. Part 1 of ISO 15489, the international standard for overall records management, was also amended in 2016. In addition, the Integrated Public Sector Vocabulary (IPSV) in the UK, EuroVoc in Europe, and Functions of New Zealand (FONZ) in New Zealand have been effectively building and linking thesauri to reflect recent trends. In this study, we propose a thesaurus construction guideline for systematic record management in terms of related standards and cases, and suggest an improvement plan for the thesaurus construction guideline in Korea.

Wire bonding process in making semiconductor needs the most precise control and Critical To Quality(CTQ). Thus, it is regarded to be the most essential step in packaging process. In this process, pure gold wire is used to connect the chip and PCB(substrate or lead frame). However, the price of gold has been skyrocketing continuously for a long period of time and is expected to further increase in the near future. This phenomenon situates us in an unfavorable condition amidst the competitive environment. To avoid this situation, many semiconductor material making companies developed new types of wires: Au.Ag wire is one material followed by many others. This study is aimed to optimize the parameter in wire bonding with the use of 6sigma and QFD(Quality Function Deployment). 6sigma process is a good means to not only solve the problem, but to increase productivity. In order to find the key factor, we focused on VOB(Voice of Business) and VOC(Voice of Customer). The main factors from VOB, VOC are called CTQ. However, there were times when these main factors were far from offering us the correct answer, thus making the situation more difficult to handle. This study shows that QFD aids in deciding which of the accurate factors to undertake. Normally QFD is used in designing and developing products. 6sigma process is held more effective when it used with QFD.

Plant can detoxify the effect of the volatile organic compounds (VOC) such as formaldehyde and toluene, however, mechanisms of VOC detoxification are largely unknown in plant system. This study was performed to investigate phenotypic changes of Arabidopsis seedlings upon treatment of either formalin or toluene. Formalin treatment up to twenty four hours didn't cause any significant phenotypic damages on the leaf surface of 27 DAG Arabidopsis seedlings. However, the protein profile of formalin-treated seedlings was significantly different from that of mock control. Using automated electrophoresis system, the molecular weight of each formaldehyde-responsive protein (FRP) was predicted and its formaldehyde-dependent expression was confirmed at transcription level by quantitative real-time RT-PCR analysis. Four FRPs isolated in this study are the novel proteins with unknown functions but highly homologous to the stress-related proteins.
