This study analyzed operating condition and the problems of damage compensation insunace (property insurance) for qualified architect and derived some suggsetions for improvement. The Certified Architects Act requires all building design and construction supervision to buy property insurance. This study proposes following suggestions to solve problems of current architect property insurance. Firstly, we need to increase the insurance purchasing rate of damage compensation insurance for qualified architect. It is necessary to clearly specify the matters concerning the submission of insurance policies by the architects, which is currently carried out by the Minister's official letter, in the form of official announcement. Secondly, proper insured amount should be adjusted. In order to insured substantial compensation capacity, total amount of insurance should be enlarged. Thirdly, the insurance period should be extended to one year after completion of building to allow compensation for accidents due to design negligence. Generally, the design defect can mostly be identified within one year after completion. Fourthly, insurance coverage should be extended. In the long run, it is essential to enlarge the scope of the security not only to property damage but also to human losses. Finally, an accident record sharing system should be established among insurance companies, so that proper insurance premiums or discounts can be made based on the system.

According to the recent judgment of Supreme Court, in case when the National Health Insurance Service pays the insurance to a victim of torts, and then subrogate the victim's claim for damages, the scope of institution's subrogation should be limited to the amount of the assailant's responsibility rate of the institution charge, and the amount of compensation claimed by the victim to the assailant should be calculated in the method of contributory negligence after deduction. The court has judged that the institution could subrogate the whole amount of institution charge in the limit of assailant's damages, and the method of deduction after contributory negligence should be applied when calculating the assailant's damages to the victim. Supreme Court decision is greatly significant in the aspect of harmonizing the nature of health insurance as property right and social insurance as the beneficiaries could get additional supplement, and also seeking the balance between insurer and beneficiary. With the changed legal principles of Supreme Court in the scope of institution subrogation like this, the necessities to complement the litigation relation, legislation, and institution were suggested.

There were also many medical-related rulings in 2021, among which the rulings reviewed in this paper are as follows. The first relates to a case in which the medical record, which is the primary judgment data regarding the presence or absence of medical negligence, has been modified. The court judged whether there was negligence on the basis of the first written medical record without considering the contents of the medical record that was later modified. Next, the ruling on the case of asking for liability for damages for prescription of anti-obesity drugs recognized negligence related to prescription, but denied liability for property damage by denying a causal relationship, and recognized only alimony for violation of the duty of explanation. The a full-bench ruling on the scope of subrogation of the National Health Insurance Corporation, which subrogates the claims for compensation for medical expenses against the perpetrator of the patient, changed the existing precedent that had taken the 'deduction method after offsetting negligence' and judged it as 'the method of offsetting negligence after deduction'. In addition, in the ruling on whether or not there was negligence, the court was not bound by the medical record appraisal result. Lastly, in relation to the National Health Insurance Service's disposition of reimbursement for medical care benefit costs, we reviewed the ruling that discretion should be exercised even when a non-medical person makes a refund to a medical institution opened by a non-medical person. And we also reviewed the ruling that the scope of reimbursement for medical institutions jointly using facilities and manpower specifically should be determined.

The purpose of this paper is to provide an ideal agreement proposal for the satisfactory settlement of FTA origin criteria negotiations, which will be the most severe issue in both inter-governmental FTA negotiations to begin in the near future. Towards this end, we, the authors, based on our nine FTA related agreements already concluded with other countries, researched the concrete origin criteria in the previous origin agreements, analyzed the characteristics of these agreements, and derived the ideal origin rule. As a result, we came to the conclusion that in consideration of Korea and China's FTA's substantial transformation test, it's better to choose any one criterion from the following. Criterion 1: CTH (Change of Heading) and Criterion 2: Value Added Criteria by 40% within region. In addition, we also did that in calculating the ratio of value added, the calculation method and price criteria should be more simple and standardized. It led to the conclusion that the objective deduction method should be used mainly and that CIF or FOB should be used as the price criterion.

Purpose : The aim of this study was to assess the validity of standard deviation of gray scale histogram in digital subtraction radiography as a test parameter for superimposition error. Materials and Methods : Twenty periapical radiographs were used as baseline images and they were copied to exclude the influence of exposure geomety and contrast differences. These subsequent images were linearly displaced by 0.1-0.5 mm in the x-. y- and xy-directions, rotated by 0.5-3° and distorted by angular contraction of 1-5° in x- and y-axis before subtraction. The standard deviations of gray levels in the subtraction images were obtained and paired t-tests were performed. Pearson correlation coefficients(r) were calculated between the standard deviations and the superimposition errors. Results : Linear displacement showed high correlation coefficients of 0.997, 0.997 and 0.995 in x-. y- and xy-axis respectively. Statistically significant different standard deviation existed among all linearly displaced groups(p<0.05). Distortion showed relatively low correlation coefficients of 0.982 and 0.959 in x- and y-axis. The standard deviations between the two distortion groups were statistically significant different(p<0.05). Conclusion : Standard deviation of gray level distribution in digital subtraction images is satisfactory but not perfect similarity measure to assess the superimposition errors.

Purpose : To determine whether subtraction images utilizing contrast media can improve the diagnostic performance of proximal caries diagnosis compared to conventional periapical radiographic images. Materials and Methods: Thirty-six teeth with 57 proximal surfaces were radiographied using a size #2 RVG-ui sensor (Trophy Radiology, Marne-la-Vallee, France). The teeth immersed in water-soluble contrast media and subtraction images were taken. Each tooth was then sectioned for histologic examination. The digital radiographic images and subtraction images were examined and interpreted by three dentists for proximal caries. The results of the proximal caries diagnosis were then verified with the results of the histologic examination. Results: The proximal caries sensitivity using digital subtraction radiography was significantly higher than simply examining a single digital radiograph. The sensitivity of the proximal dentinal carious lesion when analyzed with the subtraction radiograph and the radiograph together was higher than with the subtraction radiograph or the radiograph alone. Conclusion: The use of subtraction radiography with contrast media may be useful for detecting proximal dentinal carious lesions.

The purposes of this study were to develop the computer program for the contrast and geometric correction in digital subtration radiography with the IDL (Interactive Data Language) and compare the results with this program for the correction of the non-standardized radiographs to those of standardized radiographs and those with "Emago" software, the commercial program for the correction. The procedures were written for the contrast correction and subtraction with the geometric correction, using IDL. 32 pairs of periapical radiographs of premolar and molar portion of two dry human mandibles were taken at two different occasions with XCP film holder(nonstandardized films) and another 32 pairs with customized XCP film holder(standardized films). Subtraction of standardized film pairs was performed. Subtraction after the contrast and geometric correction of non-standardized films was performed using the newly developed program and Emago software. Standard deviations of grey levels of the subtracted images by the newly developed program were compared with those of the standardized group and Emago-corrected group. Standard deviations of grey levels of new program-corrected group were much smaller than those of the Emago-corrected group (p<0.001) and slightly larger than those of standardized group (p<0.05). However, the difference was very minute. This study indicates that the newly developed program written with IDL may substitute the mechanical standardization for digital subtraction radiography.

The purpose of this research is to investigate the dynamic roll-damping characteristics of a spin-stabilized projectile in wind-tunnel testing. In the present work, the high-speed wind-tunnel tests for the roll-damping measurements were conducted on a finned spin-stabilized projectile model in the Agency for Defense Development's Trisonic Wind Tunnel at spin rates about 8,000 rpm. The test Mach numbers ranged from 0.6 to 0.9, and the angles of attack ranged from 0 to +15 deg. The evaluation of the bearing friction parameter was also conducted to eliminate the tare damping moment from the aerodynamic damping moment.
