Recently, agriculture in Korea is experiencing difficulties such as a shortage of rural manpower, an aging population, and a decrease in the proportion of production, As an alternative, smart farming methods that converge advanced technologies such as ICT and biotechnology have developed and are being reflected in rural areas. Among them, smart farming method incorporating ICT is emerging as an alternative that can directly improve efficiency in increasing the quality and production of crops. And also smart farm that can significantly reduce the need for manpower by automating the opening and closing of environmental information and cultivation facilities, and wild animal damage prevention system that generates specific patterns of light and sound by applying AI technology to harmful wildlife, etc. IoT convergence agricultural facilities are being actively developed. However, rural areas are often located in remote areas where information and communication are not well established or established, which often makes the use of high-tech IoT agricultural equipment impossible. Therefore, in this paper, we intend to present a method for efficiently designing IoT networks in rural areas by designing, reflecting, and verifying the network of agricultural IoT facilities in rural areas.

This paper is to provide the basic way of a acoustical evaluation and efficient control noise by investigating the limits of perceptual loudness of living environment and by finding out any correlation between Physical characteristics of noise and psychoacoustic parameters. The limits of perceptual loudness were selected by the subjects in a chamber for residential and working environment. And the noise sources were analyzed to find out whether there is any correlation with Zwicker parameters and ACF factors. In this study especially, to set up the domestic evaluation grade about floor impact noise. we'd like to suggest the loudness Perception research result as fundamental resource for setting up the evaluation grade through the result that is based on annoyance. In the result of this research, upper limit of heavy-weight impact noise was L-60, and lower limit of it was L-50. On the other hand, upper limit of light-weight impact noise was L-70, and lower limit of it was L-55. It seemed that the loudness of noise from vacuum cleaner noise does not affect its perceived noisiness. Noises implicated In human such as floor walking noise and talking sound, are the most irritating noise in office environment.

Speech announcements in public places are difficult in delivering messages especially for elderly persons: as hearing deteriorates with age, understanding spoken words are difficult in noisy and reverberant spaces. In this study, the acoustical characteristics of the reverberation-induced speech announcements on the subway platforms have been investigated on the basis of hearing ability of elderly persons. In three platforms, the RTs were from 0.69 to 1.54 seconds at 1 kHz and the SPLs were varied by arriving and departing of the trains. Listening tests were performed by 20s young students and over 65-year elderly persons for the recorded sounds at different acoustical environments. As a result, high frequency boosted signals were effective to improve the speech intelligibility in noisy environment for the elderly.

본 연구의 목적은 당구참여자들의 재미와 운동중독, 여가만족의 인과관계를 규명하는데 있다. 당구참여자 207명을 대상으로 연 구를 진행했으며, 재미, 운동중독, 여가만족 질문지의 타당도와 신뢰도 검증을 거친 후 자료를 수집하였다. 수집된 자료는 기술통 계 분석, 상관관계 분석, 구조방정식모델 분석을 실시하였다. 분석결과 첫째, 설정한 연구모형은 당구참여자들의 재미, 운동중독, 여가만족의 관계를 설명하는데 적합한 것으로 나타났다(TLI=.946, CFI=.959, RMSEA=.061). 둘째, 재미와 운동중독의 경로, 운동중독 과 운동만족의 경로, 재미와 여가만족의 경로에서 정적인 인과관계가 있는 것으로 나타났다(p<.05, p<.01, p<.001). 셋째, 재미와 여 가만족의 경로에서 운동중독의 간접효과를 확인할 수 있었다(β=.264, p<.05). The purpose of this study was to examine the model indicated causal relation among fun, exercise addiction and leisure satisfaction of Billiard Participants. A total of 207 Billiard Participants in this study. In addition, exploration and confirmatory factor analysis and reliability test were conducted to verify the validity and reliability of the measurement tools. The collected data were analysis using descriptive statistics, correlation analysis and Structural Equation Model were conducted. The result of analysis is give as following. First, structural model of the study which was set to explain fun, exercise addiction and leisure satisfaction of Billiard Participants was suitable(TLI=.946, CFI=.959, RMSEA=.061). Second, fun had positive effect on exercise addiction and leisure satisfaction and also exercise addiction had positive effect on leisure satisfaction(p<.05, p<.01, p<.001).??Third, According to verification result of indirect effect about exercise addiction, which shows intermediary role between fun, and leisure satisfaction(β=.264, p<.05).
