The seismic responses of traffic light poles are investigated using a finite element analysis. Among the traffic light poles, single- and bi-directional traffic light poles are considered since such poles are frequently installed on vehicle roads. For a more detailed investigation, three different lengths of the mast arm are considered for each directional pole. For a time-history analysis, six actual and two artificial earthquakes are considered and applied to each direction of the poles (x and y) to investigate which direction input provides more significant responses due to the unsymmetrical structural shape. Herein, the x and y directions are respectively parallel and perpendicular based on the single mast pole case. From the analysis results, the average maximum displacement response is developed with the x-direction input case for both types of light poles. Also, the bi-directional traffic light poles show a 13% larger response than the single-directional traffic light poles. Even though the y-direction input case produces a smaller response, the response difference between the single- and bi-directional light poles considerably increases by about 60%. The average maximum acceleration responses are almost similar for both types of light poles.

Lyme 질환은 미국 코넷티컷주의 라임지방에서 관절염증상을 보이는 소아과환자에게서 1975년 처음 발견되었다, 사슴, 누루, 개 등에 기생하는 진드기에 의해 전염되며, 발병초기에는 감기증상을 수반한 황소의 눈과 비슷한 붉은 반점이 생긴다. 적기에 치료하지 않으면, 관절염, 심장질환, 안면신경마비 등으로 악화될 수 있다. 본 논문의 목적은 두가지로 나누어 볼 수 있다. 먼저, 진단초기의 Lyme질환과 관련된 의료 및 기타 경제적 비용을 저렴하게 계측할 수 있는 방법론을 개발하고 그 유효성을 검증하는 것이다. 둘째로 lyme질환의 비용에 대한 여러종류의 총괄적 계측치를 제공하고 발병의 위험요인을 색출하는 것이다. 본 논문에서는 차트분석이나 임상연구 등 고가의 비용이 수반되는 분석기법 대신에 Lyme질환 다발지역에 대한 설문조사를 실시하고 그 유효성을 재설문조사를 통해서 검증하는 방법을 사용하였다. 자료분석상의 난점은 조사대상자마다 응답하지 않은 항목(Missing Value)이 다르기 때문에, 총 비용을 계산할 때 모든 항목에 응답한 조사대상자만을 사용한다면 표본의 크기가 너무 작아지는 것이었다. 이에 대한 대안으로 총비용 및 부분별 비용의 합을 계산할 때 표본의 일부가 응답하지 않은 항목에 대해서는 그 항목에 응답한 나머지 조사대상자의 응답치 평균을 대체하는 방법을 사용하였다. 통계적 분석결과, 질환의 증상시작부터 설문조사시기까지 Lyme질환과 관련된 사회적 총비용은 US$ 6400으로 추정되었다. 이중에 200가량은 환자의 보호자와 관련된 비용이고 나머지는 환자와 관련되 것이다. 총의료비용의 평균은 계산방법에 따라서 US$ 3000-4200의 범위를 보였다. 응답되지 않은 항목을 해당항목에 대한 응답치평균으로 대체하였을 때 총의료비평균은 US$ 4108이었다. 시간비용을 생산성손실에 대한 사회적 가치와 실제임금 손실의 두가지 방법에 의해 계산되었다. 실제임금손실은 생산손실의 사회적 가치의 약 30%에 불과하였다. 본 논문의 결과는 의료비용 및 비용과 생산성손실에 대한 정보가 지역보건담당자에 의한 전화설문조사에 의해 경제적이고도 일관성 있게 수집될 수 있다는 근거로 해석될 수 있다.

Ulsan was selected as an industrial and industrial city, a leading city of Korean economic development in the 1960s, and it was rapidly changed social environment with the influx of many labor population. This change has had a great impact on the traditional customs of the region, and the traditional intangible culture has disappeared or disappeared, which requires urgent protection of intangible cultures compared to other regions. This study suggests the current situation to restore the agricultural music made up of the three-time customs recorded in the 1930s in Ulsan Dali area. The research method is literature research and field research. First, the literature analyzes the farming music in connection with the farming work performed in the Ulsan Dali area in 1936, and secondly, The field survey was based on the current situation of restoring farm music at the Nam-gu Cultural Center in Ulsan. The results of the research were observed in the Ulsan area, which has disappeared rapidly. In addition, it revealed the status of being handed down from 'Kim Dal-oh', a traditional farmer who worked at Ulsan Cultural Center, to 'Kim Se-ju', who is trying to restore the farm music.

The purpose of this study is to examine the implications of Deleuze and Guattari's Machinism and Pedagogy of Assemblages. A slow, empirical process offered by Deleuze and Guattari is possible only if they experience a repetition of the duration in time. The identity of this world, a combination of potential and reality, is expressed as a machine. The identity of the 'machine' is the generation. The identity of the information society that exists everywhere in the cloud and unconsciously collects big data is also the information society. The information society is at risk of leaning toward a society in which individual desires are managed prior to the manifestation of a self-reliance a machine consisting of unmarked and mechanical arrangements. Social science based on the theory of layout shares the characteristics of repetition patterns, coexistence of linguistic and materiality, attention to boundary and negation to total whole. The pedagogy of layout, in which the collective pattern is structurally deformed in time, conforms to the original problem consciousness of Deleuze and Guattari, slow and empirical education. In addition, the work of examining the materiality and expression of the education-machine will contribute to the establishment of a new learning theory, an educational theory in the era of trans-human.

Recently, a lot of data has been generated according to the diversity and utilization of information, and the importance of big data analysis to collect, store, process and predict data has increased, and the ability to collect only necessary information is required. More than half of the web space consists of text, and a lot of data is generated through the organic interaction of users. There is a crawling technique as a representative method for collecting text data, but many crawlers are being developed that do not consider web servers or administrators because they focus on methods that can obtain data. In this paper, we design and implement an improved dynamic web crawler that can efficiently fetch data by examining problems that may occur during the crawling process and precautions to be considered. The crawler, which improved the problems of the existing crawler, was designed as a multi-process, and the work time was reduced by 4 times on average.

한국농어촌공사 농어촌연구원은 하천 및 해안분야의 다양한 수리모형실험을 수행할 수 있는 대형 수리모형실험 시설을 2018년에 구축완료하였다. 국내 최대 규모의 실험장뿐만 아니라 첨단 광학용 계측장비(PIV 및 LDV 시스템)를 연계한 전용실험수로, 대형유사실험수로 등 7종의 기능별 실험수로를 갖추고 있어 다양한 수리현상 분석을 수행할 수 있다. 최근에는 산사태의 주요 원인중 하나인 토석류 실험, 방조제 주변의 침·퇴적 실험 등을 수행하였으며, 본 연구에서는 3D 지형스캐너를 활용한 방조제 주변의 지형변동 수리모형실험에 대하여 소개를 하고자 한다. 방조제는 조수가 육지쪽으로 밀려들어와 내부개발지역이나 농지 등을 해수로부터 보호하기 위해 설치되는 외곽시설이다. 이러한 방조제 전면의 빠른 유속에 의한 침식은 배후지의 안전에 상당히 큰 문제를 야기시킨다. 방조제의 침식을 방지하기 위하여 방조제 전면에 수제공을 설치하여 수제공과 수제공 사이의 느려진 유속에 의해 방조제 전면에 토사를 퇴적시키는 방법이 있다. 본 연구에서는 방조제 전면에 수제공의 길이를 달리 설치하여 수제공 주변의 침·퇴적현상을 이동상 실험을 수행하여 분석하였다. 일반적으로 토사의 침·퇴적고를 계측하는 방법으로 일정한 격자망을 구성하여 각 지점별로 실험 전·후의 토사의 표고차를 수작업으로 계측한다. 이 경우는 실험자가 직접 측정하는 계측오차가 발생하게 되고 측정할 수 있는 지점의 수가 한계가 있어 전체적인 토사의 변화양상을 분석하기엔 어려움이 있다. 이를 해결하기 위하여 본 연구에서는 농어촌연구원이 보유하고 있는 3D 지형스캐너를 활용하여 토사의 표고차를 측정하였다. 실험에 사용한 3D 지형스캐너의 최대 측정거리는 스캐너가 설치된 중심점으로부터 반경 80m에 해당하며, 해상도는 1.6mm~50mm의 범위로 수작업으로 격자망을 구성하여 측정하는 것보다 상당히 높은 수준의 결과를 취득할 수 있으며 계측시간을 단축할 수 있는 장점이 있다. 하지만, 펄스레이저에 의한 지형스캔 방식은 수면과 같이 레이저가 투과할 수 없는 경우에는 계측이 불가능하며, 어두운 계열의 색을 스캔하는 경우 결과 분석에 주의할 필요가 있다. 본 연구에서는 이동상 재료로 안트라사이트(검은색)를 포설하였고, 검은색 계열의 실험사에도 3D 지형스캐너가 우수한 결과를 제공하는 것을 확인하였다.

The purpose of this study is to critically evaluate the structural performance of an innovative new shear resistance connecting structure of precast member. Joints such as shear resistance connecting structure require special attention when designing and constructing precast segmental structures. An experimental and analytical study was conducted to quantify performance measures and examine one aspect of detailing for developed shear resistance connecting structure. A computer program, named RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology), for the analysis of reinforced concrete structures was used. A joint element is used to predict the inelastic behavior of the joints between segmental members. Future work by the authors will do a model test of precast segmental prestressed concrete bridge columns with this shear resistance connecting structure, and examined both the structural behavior and seismic performance.
