The process of getting off through the drop-off tag action using a transportation card when getting off the bus increases the incidence of sudden stop accidents. In this paper, we propose a face recognition model to prevent in-bus safety accidents that can match passengers' transportation card ride information to classify passengers' ID, ride time, and passengers' face image, and communicate face recognition and boarding/leaving information in real time in a bus environment by combining hardware. Facial image data is applied to a convolutional neural network (CNN) model through preprocessing to extract and classify facial features. In addition, a server that extracts characteristic information of an image according to the in-bus environment and an MCU(Micro Controller Unit) board that transmits images of passengers on the bus are used, and RFID is used to extract card information of passengers. Using the Raspberry PI, a web streaming server is built, and a face recognition model for preventing safety accidents on buses is implemented using Socket communication for communication with a server that extracts feature information. Through this, it is believed that it will contribute to the prevention of accidents by recognizing passengers' drop-off information only with facial information without drop-off tag action, and will serve as a cornerstone for the use and application of various safety accidents on the bus, such as safety warnings through the model.

The transition to renewable energy, especially the expansion of photovoltaic (PV) generation, has become a global megatrend that can no longer be reserved. However, since the site for PV is limited, it is necessary to use the land efficiently. As an alternative, the concept of utility scale agricultural PV(UAPV) is a technology that continues farming in the lower part and installs PV in the upper part of farmland to efficiently use the land. Therefore, for UAPV, the growth of crops in the lower part and the optimal operation of PV in the upper part are important. In this, we analyze the characteristics of the upper PV generation system in the UAPV based on the empirical results under various conditions, and propose future research directions of the UAPV.

高麗時代 驛의 運營에 관한 硏究 : 地方組織과 驛의 관계 및 驛의 運營要員을 中心으로 Focusing on the relations between local administrations and relay stations and the managerial personnel ...

劉善浩 서울産業大學校 1990 논문집 Vol.31 No.1

The Koryo Dynasty divided the country into Goon Hyun or Boo Gok. Accordingly, relay stations were organised as special administrative divisions. In Koryo, it is thought, local administrations, Goon Hyun and Boo Gok, were transformed each into other, but relay stations were not changed into another local organisation on account of the unique function in transportation and communication. A relay station had its station masters, station officials, and station employees as its personnel. Both in the declining years of the Sila Dynasty and in the beginning of the Koryo Dynasty, local squires were gradually deprived of their power in the course of strengthening of the central government and weakening of the local administrations. These aquires became station masters responsible for operating relay stations. Minor or disloyal squires in local districts, who were declined in power, became station officials. They were responsible for supplying horses, conscribing laborers, and collecting taxes. Station employees were in charge of transmitting official letters, keeping station horses, and entertaining imperial envoys.

The purpose of the general education lies in cultivating intellectuals who can form right judgement by developing a creative mind-set and a critical attitude toward solving problems. But between the teaching staff and the students, there exist differences in their points of view concerning the importance of the general education, the unit arrangement, and the educational quality and management. When the importance of the general education is understood by both the staff and the students, the conflicts can be solved, and the general education can be rightly developed, with a consensus reacted.

三國時代의 郵驛과 交通路

劉善浩 서울産業大學校 1987 논문집 Vol.26 No.1

The system of mail-travels during the Three States was established and managed, while the Three Villages were growing and developing into the Ancient States, so the royal authorities were strengthened and the territories were enlarged, in order to facilitate the transmission of decrees and make sure the government of the local provinces. The mail-travels system in Korea was first established in 487, during the reign of King Soji, Shinla Dynasty, And it was divided and enlarged into the department of shipping and the department of horse transport in the latter half of the 6th century during the reign of King Jinpyong, as the system of society were becoming more and more diversified. In the middle of the 8th century, during the reign of King Kyongdok, Kyongdo Department was established, which was wholly responsible for mailing and traveling. In the meantime, for the purpose of the military advancement and the efficient government of newly occupied areas, each State secured the travel roads, which connected its capital and local bases. Thus, above thesis ts about the establishment, management and administration of the system of mail-travels during the Three States, and also about the study of travel roads in relation to the outward expansion of the Three States.

와이어 하네스는 가전제품, 전기자동차, 자율주행 자동차에서 혈류의 역할을 하는 임의의 전기적회로의 상호 연결을 제공하는 와이어의 그룹으로 정의되며 품질이 가장 중요한 척도이다. 와이어 하네스 품질 불량은 제품 고장, 화재, 인명사고와 직결되기 때문이다. 본 논문은 와이어 하네스 압착공정 결과물인 크림프 하네스의 불량을 판정하기 위해, 다중 시멘틱 세그멘테이션 기법을 활용하는 방법을 제안하였다. 크림프 하네스의 불량 판정 문제는 전처리된 하네스 데이터로부터 연속된 5개 세그먼트들의 높이 및 폭의 길이를 정확히 측정하면 가능한 것으로 판단되었다. 이에 착안하여 대표적인 시멘틱 세그멘테이션 모델인 U-Net을 기반으로 다중 세그먼트 식별에 적합한 AI 모델의 개발을 목표로 하였다. 다중 세그먼트 식별을 위해 U-Net의 인코더 부분을 ResNet 34, EfficientNet B1 및 Mix Transformer B0로 변형한 모델을 제안하였다. 인공지능 모델 개발을 위해, 데이터셋 구축에는 와이어 하네스 제조공장에서 수집된 크림프 하네스 이미지들을 사용하였다. 개발된 다중 시멘틱 세그멘테이션 AI 모델은 테스트 데이터셋에 대해 95.14%의 판별 정확도를 나타내었다. 제안된 방법은 종래의 방법(수작업, 압착센서 측정값 및 규칙 기반의 영상처리)의 단점을 개선한, 균일한 고품질 유지와 인건비 절감이 가능하다. Wire harness is defined as groups of wires providing interconnections for arbitrary electrical circuits that serve as the bloodstream in consumer electronics, electric vehicles, and autonomous cars. Poor wire harness quality is directly related to produce product failures, fires, and human casualties. This paper proposes a method that utilizes multi-class semantic segmentation techniques to determine the defects of the crimp harness, which is the result of a product of the wire harness crimp process. The problem of defect detection of crimp harness can be solved by accurately measuring the height and width of five consecutive segments from the preprocessed harness data. With this insight, we aimed to develop an AI model suitable for multi-segment identification based on U-Net, a representative semantic segmentation model. To identify multiple segments, we proposed a model that modifies the encoder part of U-Net using Resnet 34, EfficientNet B1, and Mix Transformer B0. For AI model development, images of crimp harnesses collected from a wire harness manufacturing plant were used to build the dataset. The developed multi-class semantic segmentation AI model showed a discernment accuracy of 95.14% on the test dataset. Through the method proposed in this paper, it is possible to maintain uniform high quality and reduce labor costs, which improves the shortcomings of the existing crimp harness quality inspection(manual, crimp sensor measurements, and rule-based image processing).

高麗時代 郵驛의 管理에 관한 硏究

劉善浩 서울産業大學校 1988 논문집 Vol.28 No.1

In the first term of Koryo Dynasty, the mail-travel system consisted of 149 stations which were classified into six ranks was kept on. After the mid term, the mail-travel system consisted of 525 stations which were spotted along the 22 travel-roads was managed. The management and installation of the mail-travel roads was in charge of the central military department. Gong-Yeog-Sa (供驛署) was responsible for the transmission of the official correspondences and the pre-parationuse of horses which were available to the officials in charge of them. Po-Ma-Cha-Ja-Saek, (鋪馬飾予色) after the invasion of Mongolia, issued certificates which sanctioned the use of stations and horses. For the management of stations or travel-roads which were spotted over the country, at the beginning of Koryo Dynasty, Je-Do-Sun-Gwans (諸道巡官) were dispatched. During the period of King Hyon Jong, Gwan-Yeog-Sas (畿驛使) were sent for the maintenance of the local systems and they were given the responsibilities of the management and the facilities of the stations. Also, temporara Jeong-Yeog-Byeol-Gams (程驛別監) were dispatched for the restoration of the ruined travel-roads, and after the invasion of Mongolia, Tal-Tal-Hwa-Sons (說脫希孫) were established at the important points to prevent the desolation of the roads.

Visualization of the mixing pattern in a non-element mixer was carried out using laser induced fluorescence(LIF) to eval- uate characteristics of mixer consisting of the main flow pipe and branch flow pipes. The branch flows were injected peri- odically with the period Tin normal to the main flow, and rhodamine B was mixed into the most upstream branch flow to visualize mixing pattern in the main flow pipe by LIF. The length of boundary line L of the LIF image was measured. In this study, a numerical analysis was performed to identify the mixing process of the non-element mixer, and the results were compared with experimental results. Each result was almost the same. When the number of branch flows is increased, the mixing pattern became complicated and was supposed to become chaotic. The length of boundary line L increased exponen- tially with an increase in the number of branch flows.
