With the spread of smart speakers based on voice recognition technology and deep learning technology, not only non-disabled people, but also the blind or physically handicapped can easily control home appliances such as lights and TVs through voice by linking home network services. This has greatly improved the quality of life. However, in the case of speech-impaired people, it is impossible to use the useful services of the smart speaker because they have inaccurate pronunciation due to articulation or speech disorders. In this paper, we propose a personalized voice classification technique for the speech-impaired to use for some of the functions provided by the smart speaker. The goal of this paper is to increase the recognition rate and accuracy of sentences spoken by speech-impaired people even with a small amount of data and a short learning time so that the service provided by the smart speaker can be actually used. In this paper, data augmentation and one cycle learning rate optimization technique were applied while fine-tuning ResNet18 model. Through an experiment, after recording 10 times for each 30 smart speaker commands, and learning within 3 minutes, the speech classification recognition rate was about 95.2%.

Recently n Korea, the House of Commons and terrestrial broadcasting facilities integrated with FM radio and the satellite compulsory was amended to transfer MATV(Master Antenna Television) adjusted by SMATV(Satellite Master Antenna Television). While the SMATV was accepted by default in most other countries, our county did not accept it as the default for broadcast. Because domestic cable and satellite television service providers are conflicts with their interest. bAs a result, the hybrid amplifier for SMATV technology development and volume production for the state is insufficient. Therefore, terrestrial television broadcast bands (54 ~ 806Mhz) and FM radio broadcast band (88 ~ 108Mhz) band satellite with (950 ~ 2150Mhz) to amplify the development of a broadband amplifier with subsequent resolution of problems is also presented in this study.

The impacts of electric service interruption to customers depend on customer and interruption characteristics. Customer characteristics include demographic aspects (residential type, and number of household members) and power supply types whereas interruption characteristics include frequency, duration, time, and day of interruption. Accordingly evaluation of these customer interruption costs is very complicated and subjective. For residential customers, customer survey method seems most appropriate because interruption impact to residential customers is intangible. In other. words, the value of housework or lost leisure due to interruption is individual. Accordingly, this paper selected the customer survey method to assess the interruption costs for residential customers.

The purpose of this study was to identify the general characteristics of test subjects in association with three planned housing alternatives in different focus level of work opportunities, leisure activities and services. Subjects used in the study were people in their 50's who were surveyed in 2002. A total of 464 subjects were selected from 556 samples. Statistical significance was found between the preferred housing alternatives and the subjects' background including education level of the subjects and their spouses, monthly income, assets, subjective economic capabilities, and housing size. However, there was no statistically significant differences in recognition of housing problems for later life among groups. Groups selecting different planned housing alternatives showed statistically significant differences for some features of the senior housing. From these results, it is proposed that various designs based on the levels of work opportunities, leisure activities, and services for the senior housing should be provided to satisfy the demands.

In Japan, a lot of elderly housing types have been developed in order to meet various needs of the older person and the change of social situations. Elderly housings can be divided into three categories elderly housings for healthy older persons, elderly care homes for the healthy and elderly care facilities for the unhealthy. Elderly housings include public and private rental housings. Sometimes they can be designated only for the elderly. Elderly care homes for the healthy elderly include full fee charging elderly housing, elderly homes, low fee charging elderly homes and care houses. Elderly care facilities for the unhealthy elderly consist of full fee charging elderly care homes, group homes for the dementia, elderly health facilities, nursing homes, elderly hospitals, and so on. However "elderly care facilities" have been proved not to be efficient for the delivery of elderly welfare services nor satisfactory to the frail older person. Therefore, based on the concept of the "Normalization", daily services have been provided for the elderly in order that they can live at their own home in the community for themselves. As a result, Japan aims not only to reduce elderly welfare expenses but also to increase elderly users' satisfaction. Emphasis on non-institutionalization and in-home services, regional characterization, harmony between Hard and Soft, user oriented services, substantiality, universal design and so on are sought for the sake of those goals.

최근 기후변화에 의한 강우패턴 변화로 국지성 집중호우가 증가하고 있으며, 이로 인해 서울 강남('12), 부산('13), 울산('16), 인천, 부산('17) 등 대도시 지역에서 침수피해가 증가하고 있다. 도시침수는 하천홍수 피해와는 달리 매우 짧은 시간에 피해가 발생하며, 시설물 파괴보다는 주택, 차량, 상가 침수로 인한 재산 및 인명 피해가 높은 비율을 차지하고 있다. 또한 도시침수는 다양하고 복합적인 원인에 의해 발생되므로, 상황관리에 어려움이 있다. 현재 도시침수 피해저감을 위한 대책으로 구조적인 대책과 복구사업을 중심으로 이루어지고 있다. 그러나 짧은 시간, 높은 강도의 호우에 의해 발생하는 도시침수는 이와 같은 대책으로는 한계가 있으며, 사전 대비 대응을 위해서는 예 경보 시스템 등 비구조적인 대책이 함께 이루어져야 한다. 또한 도시침수의 실시간 분석 및 모니터링 등 상황관리지원을 위한 도시침수 통합 관리 시스템의 도입이 필요하다. 따라서 국립재난안전연구원에서는 도시침수 상황관리를 위한 "도시침수 모니터링 시스템" 개발 연구를 2014~2016년에 걸쳐 수행하였다. 도시침수 모니터링 시스템은 실시간 AWS 및 RADAR 예측강우 기반의 예 경보, 침수예상도 및 침수위험지역 정보제공, 실시간 강우빈도분석, 다양한 기상정보 제공, SNS알림 서비스 등을 제공하여 담당자의 의사결정 지원이 가능하며, 2017년부터는 시범운영을 통한 고도화를 추진하고 있다. 본 연구에서는 시범운영 결과를 통해 시스템의 적용성을 검증하고, 개선사항을 도출하였으며, 향후 도시침수 모니터링 시스템의 전국화 운영을 위해 전국 읍면동단위의 위험기준 추정 방법을 제시하고자 한다.
