Document image should be classified into detailed regions as text, picture, table and etc through the geometric layout analysis if paper documents can be converted automatically into electronic documents. However, complexity of the document layout and variety of the size and density of a picture are the reason to make it difficult to analyze the geometric layout of the document images. In this paper, we propose the method which have a better performance of the region segmentation and classifications, and the line extraction in the table region than the commercial softwares and previous methods. The proposed method can segment the document into detailed regions by using connected components method even if its layout is complex. This method also classifies texts and pictures by using separable median filter even. Though their size and density are diverse, In addition, this method extracts the lines from the table adapting one dimensional median filter to the each horizontal and vertical direction, even though lines are deformed or texts attached to them.

To recycle collected high-impact polystyrene (HIPS) wastes as liquid fuel, depolymerization characteristics of HIPS by pyrolysis was studied. The effects of temperature and time on the pyrolysis of HIPS were investigated. The depolymerization temperature and activation energy of HIPS pyrolysis increased with increasing heating rate. In general, conversion and liquid yield gradually increased with pyrolysis temperature and pyrolysis time. Each liquid product formed during pyrolysis was classified into gasoline, kerosene, light oil and heavy oil according to the distillation temperature based on the petroleum product quality standard of Korea Petroleum Quality Inspection Institute. As a result, the amount of liquid products produced during HIPS pyrolysis was in the order of gasoline》heavy oil〉kerosene〉light oil. Especially 51${\pm}$6 wt% of HIPS treated was obtained as gasoline.

In the manufacturing industry, there is a transition to multi-item production for reinforcement of competitiveness. Therefore, the hybrid manufacturing technology is increasing. Especially, many efforts in production quality improvement are made through the adoption of the manufacturing execution system and ERP, so it is necessary to operate MES for prompt and effective management. MES should improve ineffective parts in production activities while managing all stages related to production of products. If there is change in the process, the changed items should be reflected to the system. However, most manufacturing execution systems are operated passively and repetitively by system administrators. This study presents a model that system administrators can comprehensively apply reference information about production related requirements on specific line's equipment to the same equipment of other lines. The flexible response for application to production lines is possible thanks to the division of blanket application and selective application of reference information through proposed model.

The Moon administration has proposed three major directions for startup growth: the creation of a new environment, active investment, and the creation of a virtuous cycle in venture investment. The policy is progressive but not sufficient to create a startup innovation boom in the current Korean economic environment. ICT Startup support policies must pay more attention to the product release stage. For growth of startups and small businesses it is important to establish a close value chain to secure competitiveness in the global market. It is necessary to secure a bridgehead to advance into the global market, including technical cooperation with large companies and joint advancement overseas. The final goal of the startup policy should be the continuous growth of the national economy and the expansion of employment. The establishment of fair trade and the strengthening of the startup ecosystem are important to foster a startup-friendly environment. Funding programs requires a shift from general support to enhanced choice and focus.

The 4th industrial revolution is accelerating the transition to digital innovation in various aspects of our daily lives, and efforts for manufacturing innovation are continuing in the manufacturing industry, such as smart factories. The 4th industrial revolution technology in manufacturing can be used based on AI, big data, IoT, cloud, and robots. Through this, it is required to develop a technology to establish a production facility data collection and analysis system that has evolved from the existing automation and to find the cause of defects and minimize the defect rate. In this paper, we implemented a system that collects power, environment, and status data from production facility sites through IoT devices, quantifies them in real-time in a cloud computing environment, and displays them in the form of MQTT-based real-time infographics using widgets. The real-time sensor data transmitted from the IoT device is stored to the cloud server through a Rest API method. In addition, the administrator could remotely monitor the data on the dashboard and analyze it hourly and daily.

2020년 2월 중순 이루 코로나 바이러스 2019(Covid-19)로 인하여 정부의 기술창업기업 지원 방식도 전반적으로 기존의 대면 방식에서 비대면 방식으로 전환하여 현재까지 대부분 진행되어 오고 있다. 창업기업에 대한 멘토링은 특히 멘티인 창업자와 멘토가 기존에 알고 있는 관계가 아닌 대부분 처음 만나는 관계의 확률이 높음에 따라 사전에 상호간에 라포(Rapport)가 형성되지 않은 상태에서 멘토링이 이루어진다. 이로 인해 Rapport가 형성이 안된 상태에서는 서로 호감을 느끼거나, 나아가 공감대 형성, 그리고 터놓고 이야기 하여, 서로 간의 대화가 충분히 감정적으로나 이성적으로 이해하기가 어려운 경우가 대부분이다. 이러한 경우에는 충분한 멘토링이 어려울 것으로 예상할 수 있다. 따라서 본 연구는 창업 멘토링의 특수성을 감안해 볼 때 정부 기술창업지원 방식 중 기업의 성과를 높이기 위한 멘토링 과정에서 대면 또는 비대면 방식의 방법 차이가 멘토링 만족도에 영향을 주는 것을 그 목적으로 한다. 본 연구는 창업 기업의 성과를 높이기 위한 중소벤처기업부의 도약패키지 사업 중 2019년과 2020년의 제품 아카데미 사업에 참여한 283명을 대면 방식이었던 2019년 211명과 비대면 방식이었던 2020년 72명의 창업 기업 멘티들의 학습 과정에서 발생하는 배운 내용을 실천하고자 하는 학습 전이 효과 경로에 차이가 발생하는 지에 대하여 분석하였다. 자기 기입 설문 방식으로 인해 발생할 수 있는 동일방법편의를 해결하고자 구조화된 설문지 구성할 때부터 응답자의 일관성 동기를 줄이려고 하였고, 통계분석 단계에서도 다수이 방법으로 측정하는 일반 CFA 모형을 활용하였다. 실증 분석결과 비대면 방식의 창업 멘토링 방식을 학습 전이 효과 경로 결과에 있어서 조절효과가 있음을 유의한 통계적 결과고 확인하고, 사후 검증을 통해 볼 때 등분산 가정이 되지 않은 상황에서 차이가 있음을 통계적으로 유의하게 나타났다.
