The suggested method of previous Son's study dichotomized subjective response data to modeling noise exposure-response. The method used maximum liklihood estimation instead of least square estimation and the noise exposure-response curve of the study was logistic regression analysis result. The method was originated to modeling community response rate such as %HA or %A. It can be useful when the subjective response was investigated based on predicted noise level. It is difficult to measure the single source emitting noise such as railway because various traffic noise sources combined in our life. The suggested method was adopted to model in this study and railway noise-exposure response curves were modeled because the noise level of this area was predicted data. The data of this study was used by previous Ko's paper but he dealt the area as combined noise area and divided the data by dominant noise source. But this study used all data of this area because the annoyance response to railway noise was higher than other noise according to the result of correlation analysis. The trend of the %HA and %A prediction model to train noise of this study is almost same as the model based on measured noise of previous Lim's study although the investigated areas and methods were different.

This study aimed to provide fundamental insights into the digital customer experience by identifying its components and analyzing their importance and satisfaction levels among youths. To achieve this objective, the components of digital customer experience were identified through a review of prior research and consultation with experts. Subsequently, a survey was conducted with 200 youths in Seoul and Gyeonggi-do. The main findings of the study are as follows: First, The components of the digital customer experience consisted of 12 items grouped into three categories. Second, an analysis of the disparity between the importance and satisfaction levels of digital customer experience revealed statistically significant differences across all items. Third, By utilizing IPA (Importance-Performance Analysis), the digital customer experience was categorized into four quadrant, each with its own characteristics and recommendations for management: The first quadrant, the "current level maintenance area," encompassed items related to "entertainment" and "recommended service." This area is currently functioning well but necessitates continuous attention and management. The second quadrant, the "area to be supported first," included items such as "personalization," "security," "inducing participation," "privacy," and "individuality expression." Intensive management and improvements are imperative in this quadrant. The third quadrant, the "long-term improvement area," consisted of items like 'consistency,' 'information quality,' and 'convenience.' These items require focus on long-term enhancement efforts. The fourth quadrant, the "areas where efforts have already been invested," encompassed items like 'accessibility' and 'deliberation.' It appears that excessive investment has been made in these areas relative to their importance, calling for selective investments while considering the specific issues associated with each factor. These research findings serve as essential data for managing the digital customer experiences of youths.

형태(from), 층(layer), 격자(grid) 등의 요소들이 고려되는 스페이스프레임 구조는 내부기둥 없이 대공간 연출이 가능하고, 대다수의 부재들이 210MPa에서 450MPa의 항복강도를 가진 강재들이 사용된다. 최근 국내에서 용접성과 내진성 및 경제성이 확보하고 제작 효율이 높은 항복강도 690MPa이상의 고강도 강재가 개발되고 있다. 본 연구는 스페이스 프레임 구조시스템에 위와 같은 장점을 가진 고강도 강재를 적용하여 구조물의 동적응답을 알아보기 위한 내용이며, 재료 및 기하학적 비선형성에 의한 스페이스 프레임의 구조적 성능을 해석적으로 규명하고자 한다. 이를 위해 각 형태에 따른 스페이스 프레임 구조물의 모드해석 및 비선형 과도해석 등의 유한요소 해석을 수행하였다. Space frame structures considering the components such as forms, layers, grids, etc. are possible to form a large space without interior columns. Here, steels having the yield strengths of 210 MPa to 450 MPa are generally used. The high strength steel (i.e., yield strength of 690 MPa) having suitable weldability, aseismicity and economics have been recently developed. In this paper, the high strength steel is applied to the space frame structures in order to analytically find out their transient responses considering the material and geometric nonlinearities. For various circular dome types of space frame structures, the modal analysis and nonlinear transient analysis are carried out using nonlinear three dimensional finite element analysis.

본 연구는 김포공항 주변 거주민을 대상으로 항공기 소음에 대한 성가심 반응에 영향을 미치는 변수에 대해 알아보았다. 성가심 반응에 영향을 미칠 것으로 예상되는 독립변수는 소음변수와 비소음 변수로 구분된다. 소음 변수로는 항공기 소음원의 소음도와 도로소음 및 생활소음, 그리고 비소음 변수로는 인구통계변수와 태도변수가 성가심 반응에 미치는 영향을 분석하였다. 분석결과 소음 변수 중 다른 소음원의 경우는 성가심 반응에 큰 영향을 미치지 않았으며, 비소음 변수 중 인구통계 변수도 성가심 반응에 영향을 미치지 않았다. 그러나 비소음 변수 중 태도변수로 구분된 민원의 경우 성가심 반응에 큰 영향을 미쳤다. For the purpose of finding how the annoyance response to aircraft noise is affected by non-noise variables, the questionnaire survey is conducted around the Gimpo International Airport in Seoul, Korea. The non-noise variables used in this research are divided into two categories; demographic and attitudinal variables. The result of the survey suggests that aircraft noise annoyance is not affected to an important extent by other noise sources(e.g., road traffic noise and community noise etc.) and the demographic variables(sex, age, education, occupation, dwelling type and length of residence). It has been found that it is affected to an important extent by the attitudinal variables such as complaints.

This study was reviewed the noise reduction effects with installation of ‘point to point speed camera’ for controlling the speed of the car. The multiple regression analysis was performed to know how the relationship between the noise level and these parameters, such as measured traffic volume and rate of heavy vehicle and weighted average speed was changed with and without the ‘point to point speed camera’. In the analysis results shows that the less traffic volume, the more noise reduction effect has been increased and the more traffic volume, the more noise reduction effect has been reduced. And noise reduction effects by the ‘point to point speed camera’ was different from each measured point. The cause of the difference was determined that inadequate ‘point to point speed camera’ position to see the effect of noise reduction. It is determined to require a more study to improve the noise reduction effects of the ‘point to point speed camera’ such as the camera position adjustment.
