This paper is about vision system that exhibits automatic examination of the conditions of shaft's worm. The system is composed of three part : image acquisition, vision algorithm, and user interface. The image acquisition part is composed of motor control, illumination and optics. The vision algorithm examines the parts by labeling algorithm using shaft image. User interface is divided into two parts, user interface for feature registering with control value settings and user interface for examination operation. The automatic inspection system of this research is a tool for final examination of shaft worm. This tool can be practically used in production lines with simple adjustments.

A selected subject and a standardized scoring system were newly enforced at college entrance examination from 1999. A selected subject system means each student can select one subject in addition to common subject in the field of mathematical research II and a standardized scoring system means we standardize the score of each field as mean 50 and standard deviation 10 in order to adjust the degree of difficulty between fields. In the field of mathematical research II, there may exist not only difference of the degree of difficulty but also that of general studying ability between groups of selected subjects. So when we standardize score, we have to consider them. So far a linear equating which is a parametric method and an equi-percentile equating which is a nonparametric method have been published, but both of them supposed that the general studying ability between groups was equal. So in this paper an adjusted linear and percentile equating method which seems to be adequate to our entrance examination is suggested and is investigated by computer simulation.

The issuing bank performs an important role than any other parties concerned in letter of credit transaction. Nonperformance of obligation by the issuing bank frustrates whole letter of credit transaction and makes serious effect on both beneficiary and applicant. The purpose of this paper is to analyze the nonperformance of obligation by the issuing bank and to present some problems and countermeasures. For this purpose, the author examines five kinds of cases on nonperformance of obligation by the issuing bank ; improper honor relating to examination of documents, improper honor not relating to examination of documents, improper dishonor relating to examination of documents, improper dishonor relating to handling procedure of documents, and improper dishonor not relevant to letter of credit transaction.

In this paper, we focus on churn analysis for the first successful candidates in the entrance examination on 2006 year using Clementine, data mining tool. The goal of this study is to apply decision tree including C5.0 and CART algorithms, neural network and logistic regression techniques to predict a successful candidate churn. And we analyze the churning and nochurning successful candidates and why the successful candidates churn and which successful candidates are most likely to churn in the future using data from entrance examination data of K university on 2006 year.

In this paper, the power simulation is used for the prediction of regenerative energy and examination of install location of regenerative inverter for DC railway system. The power simulation was composed to train performance simulation(TPS) and power flow simulation. We performed the power simulation for Seoul subway line 5 and 7, calculation of regenerative energy and examination of substations where regenerative inverter is installed.

US NRC issued rulemaking of 10CFR50.55a to perform the Perservice and Inservice inspection for Reactor Vessel Head Penetration Nozzle of US Nuclaer plant. The rulemaking was required the EPRI Demonstration to verify the NDE technique performing special Ultrasonic examination. In order to meet this requirement, the UT and ECT procedures was demonstrated and the NDE personnel were qualified by EPRI. In this paper, the NDE technique and analysis method are described the Preservice inspection for the Palo Verde #1/2/3 Replacement Reactor Vessel Head Penetration Nozzle using the qualified procedures and personnel.

This paper describes the failure mechanism and Charpy impact test of Fiber glass Reinforced Plastic composites which it was actually used for side plate of vessel. There are two examinations. The examination I, the specimens which it given temperature range $-25^{\circ}C$-$50^{\circ}C$ and with different initial notch length did impact test and then it compared impact energy(Uc) and impact fracture toughness(GIC). The examination II, the specimens which it putted into fresh water and sea water for scheduled hours did impact test and it compared impact energy(Uc) and impact fracture toughness(GIC). From examination I, it showed that impact energy(Uc) and impact fracture toughness(GIC) were peak at ambient temperature and decrease as temperature reduced. Fracture toughness(GIC) showed increase as initial notch length reduced. From examination II, impact energy(Uc) and impact fracture toughness(GIC) tended to increase which specimens putted in fresh water compared with sea water and maximum tolerance rate tend to decrease as permeation hours will be long.

Coronavirus disease 2019 (COVID-19) has had a significant impact on our society as a whole. The COVID-19 pandemic is not only a health crisis, it is also an economic, social and humanitarian crisis. Considering the dramatic global economic and social impact that the crisis has engendered, the aviation system is standing on the doorstep of rapid transformation. In particular, the impact on the aviation and travel industries is enormous. Air travel to most countries has been suspended and blocked. Looking at Korea's current situation, COVID-19 has wholly changed the aviation industry. As COVID-19 spreads around the world, countries have come up with aviation safety measures. Infectious disease safety measures were established to protect passengers and crew members, and countries with collapsed medical systems extended the validity period for aviation medical examinations. In Korea, on August 11, the Ministry of Land, Infrastructure and Transport provided guidance on medical measures related to COVID-19 through an official letter of "Notification of cautions for pilots and air traffic control officers (ATCO) when COVID-19 is confirmed". Overseas countries such as the United States and the United Kingdom have announced regulations for aviation medical examination regulations in relation to COVID-19, and have set standards for returning to aviation after COVID-19 is confirmed. In this paper, we would like to investigate the regulations for aviation medical examination related to COVID-19.

Objectives : To provide foundation for research on local medical examination of the Ming period, the contents on 'He who does not know Yi(易) cannot speak of medicine' in the Yixuetongzong(醫學統宗) written by He Jian was analyzed. Methods : Proofreading of the original texts, followed by interpretation of words and phrase and translation into Korean were done. The resulting contents were then analyzed from the perspective of the theory of Medical Yi(Yi-Yi). Results : In this medical exam paper for physicians, He answers himself on topics such as the Four Symbols[四象], Eight Symbols[八象], the Sixty-four hexagrams[Liushisigua], the combinations of the Organs and Bowels[Zangfu], Nine Orifices[Jiuqiao], and Five Body Parts[Wuti], the origin of the pulse, the reasoning behind calling the pulse 'the station for blood[xuezhifu]', what the 'Tianzhen Weihezhi Qi' stands for and the meaning of the Twelve Organs[shierguan]. He also supports the perspective of the 'Medicine and Yi having the same roots[Yi-yi tongyuan]', arguing that due to this, the body's physiology could be explained through the theories of Yi[易]. This shows that He understood the Yi-yi theory as a larger category. Conclusions :He's medical exam paper reflects his uniqueness in the field of the Yi-yi theory that precedes that of Zhao Xianke.
