Purpose: This study aims to improve on-site inspection and report of three-classes buildings. Method: For the purpose of the study, problems with field inspection and report of three-classes buildings were organized into five-point clock scale for the diagnostic inspection engineer and conducted a survey of 79 people. Results: The structure cannot be verified as it is constructed with finishing materials outside the site structure. As a result, there area many problems in objective evaluation as it is difficult to investigate whether a facility is defective during an on-site inspection. Therefore, it is desirable to re-select the finish and deploy the inspection tools considering maintenance at the time of initial design. Additional inspection tools for major structural parts and installation of inspection tools for remodeling work are required. Copying and pasting reports are considered to be similar in the preparation of a large number of reports, and are considered to be the same defect investigation details as the previous inspection results, and the inspection engineer prepares the report, which is suitable for building characteristics of the building and is not conducive to maintenance. Conclusion: It was found that improvement of consciousness education of the managing body, verification of structure by finishing materials, education of inspection engineers, improvement of the checklist of three types of facilities evaluation, inspection of the intention of the managing body of the facility, and comprehensive conclusion and survey contents and inconsistency are needed to prevent shortage of inspection time.

To remove software defects and improve performance of software, many developers perform code inspections and use static analysis tools. A code inspection is an activity that is performed manually to detect software defects in the developed source. However, there is no clear criterion which source codes are inspected. A static analysis tool can automatically detect software defects by analyzing the source codes without running the source codes. However, it has disadvantage that analyzes only the codes in the functions without analyzing the relations among source functions. The functions in the source codes are interconnected and formed a social network. Functions that occupy critical locations in a network can be important enough to affect the overall quality. Whereas, a static analysis tool merely suggests which functions were called several times. In this study, the core functions will be elicited by using social network analysis and DEA (Data Envelopment Analysis) for CUBRID open database sources. In addition, we will suggest clear criteria for selecting the target sources for code inspection and will suggest ways to find core functions to minimize defects and improve performance

허서정,손동철,김창석 한국융합학회 2017 한국융합학회논문지 Vol.8 No.1

본 논문은 플립드 러닝을 기반으로 한 컴퓨터 활용 수업의 효율적인 학습 방안을 제안한다. 기존 전통적 컴퓨터 활용 수업은 강의와 실습을 병행하여 충분한 실습 및 협력적 수업이 어려웠다. 그러나 플립드 러닝 방식의 수업 방식을 적용한 수업에서는 KOCW(Korea Open Courseware)을 디딤 영상으로 활용하여 강의실에 들어오기 전에 미리 학습하고, 강의실에서는 상호 토론을 기반으로 협력적 실습수업을 수행하였다. 수업을 진행 한 후 학습동 기 검사 도구를 이용하여 성별, 학년별, 전공별로 학습동기와 학습만족도를 측정하였다. 실험 결과 학습자의 학습 동기에서 주의 집중 인식 정도, 수업 관련성에 대한 인식 정도, 학습만족도에 대한 인식 정도가 ‘매우 만족’과 ‘만족’ 이 90% 이상으로 분석되었다. This paper suggests efficient learning improvement method of computer use instruction based on flipped learning. Traditional computer use classes were difficult to practice and collaborative with sufficient lectures. However, we used KOCW (Korea Open Courseware) as a footsteps in the class using the flipped learning method and learned in advance before entering the classroom. In the classroom, we conducted collaborative hands on class based on mutual discussion. After the instruction, we measured learning motivation and satisfaction by gender, grade, and major using the motivation test tool. The results showed that degree of attention awareness, perception of class relevance and perception of learning satisfaction were analyzed as 'very satisfied' and 'satisfied' more than 90%.

Jae-Kyung Lee,Joon-Young Park,Byung-Hak Cho,Ki-Yong Oh 대한전기학회 2012 Journal of Electrical Engineering & Technology Vol.7 No.1

The current paper deals with a new live-line insulator inspection tool system that will be used by the Korea Electric Power Corporation for its 154 kV power transmission lines in 2011. Unlike the existing contact type tools, the developed inspection tool automates parts of the insulator inspection process using a sensor and an actuator. The tool sustains its weight independently, not by a lineman. In addition, the inspection tool measures the insulation resistance of an insulator together with its distribution voltage, thus providing more information for analysis and diagnosis. Such characteristics improve the system’s operation efficiency, measurement reliability, and usability. We confirmed its effectiveness through live-line field tests with actual power transmission lines.

Shareholders` demands for access to the internal information of a corporation have increased. It is necessary to review Korea`s the legal principle of the inspection of books and records through the comparative balancing between shareholders' rights and company`s interests. Considering the form of regulations in the Korea Commercial Act, it seems that the company must prove the reason for denying inspection of the books and records by shareholders. However, Korea`s the lower court unfairly limited the shareholders` right as if the burden of proof was on the shareholders. It is impressive that the Korea Supreme Court recently declared that the burden of proof for denying the inspection is on the company. In the United States, the right to inspect of books and records is derived from common law. Based on the right, not only accounting books but also various company documents such as shareholder lists, minutes of the board of directors are also included in the range of the right. On the ground of the right, shareholders can acquire electronic information such as e-mails, text messages and electronic communication contents made by board members. It is noteworthy that a U.S. court can order certain limitations like the period and usage of the books and records which are given by the company to the shareholders. In the legal principle of the ‘fishing expedition’ under the Civil Procedure Act of Korea, the disadvantages of the submitter and the document applicant should be balanced. In Korea, there is little discussion of company confidentiality about the right. Moreover, it is very difficult to shape the contents of corporate confidentiality firmly. For this reason, it is necessary to expand the discretion of the court about the right. In the Korea civil procedure law, trial procedures about the right are under the adversary system. The trial procedures of the right should be revised as non-contentious procedures like the appointment of the inspector and the inspection of minutes of board of directors` meeting. To restrict the right, the legal system should be modified to give the court some discretion to impose sanctions on inappropriate use by shareholders. In response to these modifications, the Korea court should expand the right of inspection of books and records to shareholders.

Image-Based Inspection Technique of a Machined Metal Surface for an Unmanned Lapping Process

Dinuka Ravimal,Hanul Kim,Daegwon Koh,Jin Hyuk Hong,Sun-Kyu Lee 한국정밀공학회 2020 International Journal of Precision Engineering and Vol.7 No.3

This paper presents a new machine vision framework for the effi cient examination and classifi cation of surface textures on medium- and large-sized mold products, such as used for automobiles, TVs, and refrigerators. Existing techniques, which are based on the hands and eyes of skilled workers, are inconsistent and time-consuming. Although there are many types of precise surface inspection and measurement methods, most are diffi cult to apply at industrial sites or by fi nishing robots due to problems such as speed, setup limitations, and robustness. This paper proposes two techniques based on image processing that aims to automate surface inspection during an unmanned lapping process that is mainly employed to eliminate milling tool marks. First, both the shape of the refl ected light and the intensity of the captured near-fi eld contrast image right after the refl ected specular are used to determine the machined surface state, and the presence of tool marks as the line light source scans counter-clockwise. Second, the photometric stereo technique is used to detect surface scratches through the normal map that recovers the surface. The proposed techniques show localized machined patterns and classify them with high accuracy.
