인터넷 전화는 VoIP를 이용하는 전화 방식으로서 VoIP 단말이 인터넷에 연결되어 있다면 저렴한 요금과 다양한 부가서비스가 가능한 방식이다. 하지만 인터넷 전화를 관리하기 위한 시스템들은 대규모의 VoIP 서비스 사업자들이나 대기업에서의 사용을 목적으로 하여 개발되어 오면서 설치 및 관리의 편의성 부분이 결여되어 있으며, 이러한 문제점들은 VoIP 단말 설치를 어렵게 하여 인터넷 전화 보급에 장애가 되어 왔다. 본 논문에서는 이러한 문제를 해결하고자 VoIP 단말들의 설정 관리를 목적으로 하는 자동 프로비저닝 시스템을 설계하고 구현한다. 이 시스템은 SOHO 환경과 같이 소규모 VoIP 환경에서 VoIP 단말들을 쉽게 설치하고 관리할 수 있도록 지원한다.

Human papillomavirus (HPV) infection is the leading cause of cancer mortality among women worldwide. The molecular understanding of HPV proteins has significant connotation for understanding their intrusion in the host and designing novel protein vaccines and anti-viral agents, etc. Genomic, proteomic, structural, and disease-related information on HPV is available on the web; yet, with trivial annotations and more so, it is not well customized for data analysis, host-pathogen interaction, strain-disease association, drug designing, and sequence analysis, etc. We attempted to design an online reserve with comprehensive information on HPV for the end users desiring the same. The Human Papillomavirus Proteome Database (hpvPDB) domiciles proteomic and genomic information on 150 HPV strains sequenced to date. Simultaneous easy expandability and retrieval of the strain-specific data, with a provision for sequence analysis and exploration potential of predicted structures, and easy access for curation and annotation through a range of search options at one platform are a few of its important features. Affluent information in this reserve could be of help for researchers involved in structural virology, cancer research, drug discovery, and vaccine design.

This paper presents a computer program for easy and rapid disease diagnosis of olive flounder diseases. To design the program, standard diagnosis process of the 14 olive flounder diseases was first setup, then implemented four-steps diagnosis program. To run program, first input fundamental information such as water temperature, size of the diseased fish. Then sequentially, three categories of key factors for disease diagnosis which include external clinical signs, internal clinical signs and microscopic observations are selected. When a user selects the observed signs of olive flounder from the listed options, the program provides maximum 5 presumed disease candidates in order. The disease information, treatment and prevention methods are provided by connected web server through internet. The program would support fish doctors and farmers by providing easy and rapid diagnosis of diseased olive flounder.

The purpose of the study is to survey the needs of the elderly for ICT-based Elderly Home Remodeling by Applying Kinetic Principle. This is conducted for elderly people over 60 years old living in Seoul and Gangreung district. The study is performed by the following approaches: First, This study is based on 'the Elements of Planning for ICT-based elderly Home Remodeling by applying Kinetic Principle'(Lee 2018). Second, the needs survey for house remodeling was conducted for elderly. Finally, To analyze the required characteristics of the elderly for remodeling by using SPSS statistics 25 analysis program. The conclusion of this study is as follows. Priority elements for house remodeling should be provided to ensure the safety of the elderly through emergency call buttons, glucometer, pressure-measuring gauge, weighing instruments, and warning devices. Kinetic principles should be applied to make minimal structural changes, as easy as possible remodeling, and devices should be designed to be easy to operate.

In this research, we developed a design system for a compressor of an air conditioner using solid CAD system. The developed design system has some characteristics. First, the design system used a configuration design method, so a designer can design a compressor very quickly by using the constructed master libraries. Next, the system was developed to be used not only by engineers but also by salesmen. It is very easy for a user to use it, so a salesman can get a result very easily with the design system. And it has some design modules which give a considerable convenience to designers. Actually, designers are accustomed to the module based design. Then, it has calculation and analysis functions. Volume and mass of a part, and interference between parts are calculated by using the geometric calculation function of a solid CAD system. Also a packaging calculation was implemented to get the smallest space to package compressors for transportation and storing. An interface with a program to analyze the vibration of a compressor was developed in this design system. The design system is similar to CBD (Case-Based Design) system in the view of the whole design process.

In the modern design technology, a component should be designed to fit into the overall system performance. A design methodology is developed to expedite the mechan- ical design of complex mechanical systems, The relation between the system design and component design is defined by a top-down approach and the results from the system design are utilized in the component design process. As a design example, an automobile exhaust system is selected for the system design and a bellows is chosen for a component design. Design methodology based on the top-down approach consists of five steps; (1) Analysis of service load, (2) Development of a lumped parameter, (3) Completion of the system design, (4) Selection of the component topology, (5) Completion of the component design, A method using a equivalent matrix is developed in order to determine unknown external forces in linear structural analyses. The bellows is also analyzed by the finite element method using a conical frustum shell element. Various experiments are performed to verify the developed theories. The top-down desi- gn approach is demonstrated by a design case using structural and shape optimization technology. Since the method is relatively simple and easy compared to other methods, it can be applied to the general design where system and component designs are involves simultaneously.

본 논문은 TV 출력 기능이 필요한 기기를 위한 비디오 인코더의 설계에 관한 것이다. 설계된 비디오 인코더는 International Telecommunication Union-Radiocommunication (ITU-R) BT.470 표준을 모두 지원한다. ITU-R BT.470에는 NTSC, PAL, SECAM의 3가지로 구분되는데, NTSC와 PAL은 색차 신호를 전송하기 위해서 진폭변조(AM)를 사용하고, SECAM은 주파수변조(FM)를 사용한다. SECAM에서는 anti-cloche 필터가 필요한데, 표준(ITU-R BT.470)에서 권장하는 필터의 특성이 아주 예리해서 이전까지는 아날로그 필터를 사용하여 설계하였다. 본 논문에서는 anti-cloche 필터를 디지털 필터로 설계하고 필터의 특성을 설계하기 쉽도록 바꾸었다. 그리고 표준에서 요구하는 결과와 동일하도록 수정된 변조 방법을 제안한다. 또한 핸드폰 등의 모바일 기기에 적용 할 수 있도록 동작 모드에 따른 소비전력을 가변 하였다. 제안된 비디오 인코더는 Altera사의 FPGA APEX20K1000-EBC652-3과 삼성 LCD-TV를 이용하여 실시간 검증을 수행하였다.

The purpose of this study was to investigate the shopping condition of Dongdaemoon Shoppingmall. A depth interview was administered to eight consumers aged 10s through 30s who had shopping experiences at Dongdaemoon Shoppingmall. The contents of interview were about the reasons of preference for Dongdaemoon Shoppingmall, the merchandise categories purchased, assortment, price, shopping environment, and service offered by Dongdaemoon Shoppingmall. The results of this study were as follows: The reasons of consumers' Dongdaemoon Shoppingmall preference were reasonable price, variety of merchandise assortment, easy catch of fashion trend, entertainment place, and opening hour at nighttime. The mainly purchased items were casual and fashionable clothes. Children's wear was mainly bought item by housewives too. The unique design, similar merchandises sold at department stores and new style in early adoption of fashion cycle were perceived as positive aspects, but copied merchandises and large quantity of same merchandise as negative aspects. The fixed price system was not trusted by consumers. Consumers' complaints about shopping condition were crowded pathways and shopping booths, the lacks of facilities such as fitting room, toilet, lounge area, sales persons' service, and difficulty of using credit cards. From these results, some implications for marketing strategies and practices might be suggested. In order to improve the design variety of merchandises, marketers and apparel manufacturers should make efforts by managing merchandise planning, production, selling, and promotion cooperatively. Fixed price system, acceptance of credit cards, and merchandise return/exchange service should be improved. The training the salespersons was the most important and basic step and easy way to get to successful business.
