예비 청년 창업농을 대상으로 개인적 특성을 파악하고 개인적특성, 사회적인식, 네트워크, 창농정책, 자기효능감, 주관적규범을 조사하여 창업의도에 영향을 주는 요인들을 파악하고자 하였다. 개인적 특성의 하위 변수로 성취욕구, 위험감수성, 혁신성을 설정하여 자기효능감, 주관적규범, 창업의도와의 관련성을 연구 하였다. 본 연구의 자료 수집을 위한 설문조사는 2018년 10월 2일부터 2018년 10월 27일까지 농업관련 창업교육 프로그램을 수강하였거나 농업분야에 관심이 있는 청년 농업 예비 창업자들에게 본 연구의 목적과 취지를 설명하고 연구의 동의를 얻어 설문지 300부를 배부하였다. 배부된 설문지 중 263부가 회수되었으며, 설문지 중 미응답이 한 문항이라도 있거나 불성실하게 응답한 설문지 15부를 제외한 248부를 최종분석 자료로 활용하였다. 본 연구의 결과는 다음과 같다. 청년 농업 예비창업자의 창업의도에 영향을 주는 요인으로 개인적 특성 중 위험감수성과 혁신성이 파악되었다. 또한 상관관계에서도 혁신성과 위험감수성은 상관관계가 높은 것으로 분석되었다. 그리고 환경적 요인인 사회적 인식, 네트워크와 창농정책은 모두 창업 의지에 영향을 주는 것으로 검증되었다.

In this paper, we studied on AR model order decision for extraction of EMG median frequency by t-test and ANOVA and comparison of median frequency. And we extracted well-known parameters such as zero crossing rate(ZCR), low band energy(Band) and median frequency(MDF) from surface electromyogram (EMG). And we compared to evaluate themselves as measures for fatigue.

In this paper, we address the problem of center lane detection algorithm for autonomous driving. Color information for center lane is gathered by analyzing a row line color distribution of road in front of a vehicle. The candidate pixels for center lane are extracted from the histogram of road colors. Morphological filtering and clustering process are applied to the candidate pixels to extract the exact center lane. We predict a expected area of center lane and search only the regions in subsequent frames, that reduces the time required for center lane detection.

This study aims to identify topics in newspaper articles related to fine particle matter and to investigate the characteristics and time series trend of each topic. Related national newspaper articles during 1990 and 2021 were collected from Bigkinds. A total of 18 topics have been discovered using LDA, and 11 clusters deduced from clustering. Hot topics include related products/residence, overseas cause(China), power plant as a domestic cause, nationwide emergency reduction measures, international cooperation, political issues, current situation & countermeasure in other countries, and consumption patterns. Cold topics include the concentration standard and indoor air quality improvement. These findings would be useful in inferring the political direction and strategies. In particular, the consumer protection policy should be expanded as the related market is growing. It will also be necessary to pursue policies that will promote public safety and health, and that will enhance public consensus and international cooperation.

This paper suggests a way to improve Korean diaspora-related subject headings based on the analysis of terminology about Koreans in Korean diaspora-related manuscripts and investigation of related terms in the National Library of Korea subject headings. After selecting three KCI journals with high ratios of diaspora-related papers, the study extracted Korean-related terminology from the journal papers and examined their term frequencies. Additional Korean-related terms were investigated by manually reviewing the articles in which extracted terms appear. Based on these analyses, the study proposes several supplemental enhancements to Korean-related topic names in the National Library of Korea's subject headings, such as changing the English notation, adding non-preferred words, and changing the hierarchical relationship of the existing topic names.

Background: The need for regulatory science development to evaluate advanced regulatory products is gradually increasing without hindering the technological development. Creating a research environment and fostering experts through the establishment of regulatory agency-led policies are essential for the development of regulatory science. Method: This is a comparative study of the United States, Japan, Singapore, and Korea. The literature and websites of each regulatory agency were reviewed, and the focus was on advantages and comparing advantages based on definition, development trends, and expert training projects. Results: The United States is striving to develop regulatory science in response to changes in the new pharmaceutical industry through the regulatory science report, and to foster expert both inside and outside the Food and Drug Administration (FDA). Japan is promoting regulatory science centered on regulatory science centers, and is focusing on researching work-related regulatory science within the Pharmaceuticals and Medical Devices Agency (PMDA) and improving employees' ability to make regulatory decisions. Singapore was aiming to improve Southeast Asia's regulatory capabilities under the leadership of Centre of Regulatory Excellence (CoRE) within Duke-NUS University. In 2021, Korea is in its early stages, starting to run a university's degree program related to regulatory science this year. Conclusion: Regulatory science should be developed with the aim of improving the regulatory ability of the Ministry of Food and Drug Safety with Korea's independent concept of regulatory science.

In this paper, the centralized dynamic load-balancing was processed effectively by using the network based parallel genetic algorithm. Unlike the existing method using genetic algorithm, the performance of central scheduler was improved by distributing the process for the searching of the optimal task assignment to clients. A roulette wheel selection and an elite preservation strategy were used as selection operation to improve the convergence speed of optimal solution. A chromosome was encoded by using sliding window method. And a cyclic crossover was used as crossover operation. By the result of simulation for the performance estimation of central scheduler according to the change of flexibility of load-balancing method, it was verified that the performance is improved in the proposed method.

In similarity join processing, a general technique employs a generation-verification framework, which includes two phases: the first phase generates a set of candidate pairs from a collection of records; and the second phase verifies each candidate pair by computing real similarity. In order to reduce the number of candidate pairs in the verification phase, the median of one record of each candidate pair is used as a filter in this paper to test whether the other record can has the proper number of overlapped tokens. We propose a similarity join algorithm with the median filter, and show that the proposed algorithm has better performance in execution time than recent algorithms without the filter through extensive experiments on real-world datasets.

We are developing a minimized integrated public address system that has facilities such as external input, Mic., CD, MP3 and Radio. In this paper, developing an integrated public address system with operational MICOM will make it possible to control the facilities of digital devices centrally. The operational MICOM is composed of 3 layers which are a control layer, a processing layer and a user interface layer. The control layer controls digital devices in the integrated public address and the processing layer is for processing voice data editing, controlling signals of devices and providing status information of the device. The user interface layer displays the status of control devices and the data processing of a user. A remote control is used for the central control.

The incidence of heterotopic ossification (HO) was reported to be higher in combat-injured patients than in civilian trauma patients. HO is often considered a possible cause of residual limbs pain in amputee. Here, we report the case of a 21-year-old male, who underwent a traumatic right transfemoral and left transtibial amputation with two segments of painful HO around his left amputation site. We report the effect of extracorporeal shock wave therapy (ESWT) on size and pain associated with HO. After ESWT, the visual analog scale score decreased from 5~6 to 0~1 and the size of two masses decreased from 13.1 × 6.7 mm and 12.5 mm to 11.9 × 4.7 mm and 12.2 mm, respectively. To the best of our knowledge, this is the first case that has reported on the treatment of HO using ESWT for a traumatic transtibial amputation patient. The case suggests that ESWT could serve as a complementary treatment for HO in traumatic amputation patient.
