Objective: We aimed to evaluate the reporting quality of research articles that applied deep learning to medical imaging. Using the Checklist for Artificial Intelligence in Medical Imaging (CLAIM) guidelines and a journal with prominence in Asia as a sample, we intended to provide an insight into reporting quality in the Asian region and establish a journal-specific audit. Materials and Methods: A total of 38 articles published in the Korean Journal of Radiology between June 2018 and January 2023 were analyzed. The analysis included calculating the percentage of studies that adhered to each CLAIM item and identifying items that were met by ≤ 50% of the studies. The article review was initially conducted independently by two reviewers, and the consensus results were used for the final analysis. We also compared adherence rates to CLAIM before and after December 2020. Results: Of the 42 items in the CLAIM guidelines, 12 items (29%) were satisfied by ≤ 50% of the included articles. None of the studies reported handling missing data (item #13). Only one study respectively presented the use of de-identification methods (#12), intended sample size (#19), robustness or sensitivity analysis (#30), and full study protocol (#41). Of the studies, 35% reported the selection of data subsets (#10), 40% reported registration information (#40), and 50% measured inter and intrarater variability (#18). No significant changes were observed in the rates of adherence to these 12 items before and after December 2020. Conclusion: The reporting quality of artificial intelligence studies according to CLAIM guidelines, in our study sample, showed room for improvement. We recommend that the authors and reviewers have a solid understanding of the relevant reporting guidelines and ensure that the essential elements are adequately reported when writing and reviewing the manuscripts for publication.

Turnkey project in construction which accounts for about $10\%$ of the total annual construction orders in the nation is expected to grow in size as an effort to strengthen international competitiveness and improve quality of construction work. However, problems of turnkey project in construction raise concern for many possible cases of possible claims. Based on the understanding that bidding guidelines which plays a critical role in turnkey project in construction actually contain some unequal clauses and causes for problems which undermine development of turnkey construction and further create possible cases of claims, the paper aims to identify and analyze the unequal clauses and problems contained in the guidelines in order to make suggestions for improvement. Among all the turnkey construction orders that has been placed since 2000 when domestic turnkey project in construction became relatively formulated, 13 constructions costing more than 50 billion won were selected for this study since their construction scale were large enough that the bidding guidelines for them were regarded as containing little difference among one another. In order to enhance construction technology and to prevent claims while trying to achieve the original purpose of Turnkey system, the parties involved in or schedule to take part in Turnkey project including ordering institution, Construction Company and Design Company should make an effort to have more reasonable bidding guidelines drawn up.

Asthma is a chronic inflammatory disease of the airway and the prevalence rate is increasing. As the burden of asthma to the society is significant due to the increasing hospital admissions and emergency visits, National Heart, Lung and Blood Institute (NHLBI, USA) and World Health Organization (WHO) have developed comprehensive guidelines to help clinicians and patients make appropriate decisions about asthma care. The aim of study was to analyze the pattern of asthma prescriptions based on the national asthma guidelines for the patients visiting primary health care providers. Prescription data for asthma were obtained from the Korean National Health Insurance claims database of January 2002. Ten percent of the primary health care providers were sampled based on their specialty areas, and 20％ of the claim cases were randomly chosen. Study results showed that prescription rate for oral beta-2 agonists was 44.3％, and that for oral theophylline was 46.9％. Oral steroids were prescribed for the 28.2％ of the claims. Utilization of inhalers was low for both bronchodilators (20.3％, beta-2 agonists inhalers), and steroids (8.4％ steroids inhalers). Bronchodilators were more preferred to the longterm anti-inflammatory controllers among the primary health care providers. Prescription rate for antibiotics was 46.0％ for asthmatic patients. Also gastrointestinal drugs were prescribed for 59.0％, antitussives 65.3％, antihistamines 25.3％ and analgesics 29.4％, respectively. This study presented that the prescribing pattern of the primary health care providers for the asthma was quite different from the national and international guidelines. More efforts need to be made to reduce the gap between the present pattern of asthma prescription and the guidelines.

This article concerns the labeling guideline for health benefits of livestock products. In recent years, livestock products with health benefits have emerged as a key market for livestock product industries. However, the current labeling regulation for functional foods severely prohibits livestock product industries from attaching most of the health benefits claims to the products. Also, manufacturers have some difficulties in labeling the health benefits of certain livestock products because of a lack of guidelines on health benefit claims for livestock products. Therefore, some livestock product industries and scientists have strongly demanded a revision of labeling regulation, Appended Chart No. 14 provided by Article 52 (2) of Enforcement Regulation of the Processing of Livestock Products Act, so they could mark the health benefits on their products. To support the 'revision of labeling regulation', the goals of this article were as follows; 1) to assess the current situation on nutrition labeling and nutrition claims on foods, 2) to determine the current situation on health claim regulatory systems used in foreign countries (CODEX, USA, Japan, EU, and Australia/New Zealand), 3) to assess the current situation on the health claim or health benefit claim regulations for functional foods, conventional foods, and livestock products in Korea, and 4) to determine the need for complement in health benefit claim for livestock products. In conclusion, guidelines for the use of health benefit claims on livestock products should be prepared as soon as possible and the guidelines should be viable and easy for manufacturers and control authorities to understand. Also, nutrient profiles should be developed to identify whether the livestock products are eligible to bear health benefit claims and to help consumers make the right choices.

Background and main issue: In the Korean insurance market, an outstanding issue is the decrease of margin of risk ratio. This affects the solvency and profitability of insurance companies. Insurance medicine, which has been developed in Western countries, is so-called medical risk selection or medical underwriting. Medical risk selection is based on clinical follow-up study and mortality analysis methodology. Unfortunately, there have been few clinical follow-up studies, and no intercompany disease analysis system is available in the Korean insurance market. In practice, we use underwriting guidelines, which were developed by some global reinsurance companies. However, these guidelines were developed under clinical follow-up studies performed abroad. So, we cannot rule out underestimation of excess mortality factors such as mortality ratio, excess death rate, and life expectancy. It is necessary to perform medical assessment in claims administration. Comparing the insured's statement by medical records with products' benefit according to this procedure, we can make sound claim decisions and participate in the role of sound underwriting. We can call this scientific procedure as the verification of medical claims review. Another area of medical claims review is medical counsel for claims staff. Result: There is another insurance medicine in addition to medical risk selection. Independent medical assessment by medical records of insured is medical claims review. Medical claims review is composed of verification and counsel.

Two categories of cosmetic products, cosmetics and quasi-drugs, have been established by the Ministry of Health, Labor and Welfare (MHLW) in Japan. Japanese pharmaceutical law has defined that products categorized as cosmetics do not exhibit any effects on human skin. In fact, cosmetic products are not permitted to claim any efficacy. On the other hand, products in the quasi-drug category can claim several efficacies such as anti-inflammatory effects, whitening/lightning effects, hair growth effects and so on. Unfortunately, the Japanese MHLW has not yet approved the efficacy of anti-aging/anti-wrinkle effects as a claim point. However, the population is aging, and the demand for anti-aging/anti-wrinkle products is increasing year by year. Japanese cosmetic companies have proposed to the MHLW that anti-aging/anti-wrinkle agents be approved as a claim concept of a quasi-drug. However, unified evaluation methods for anti-aging/anti-wrinkle effects have not been established. Currently, each company evaluates the efficacy of products/materials using their own original methods. Thus, to request approval of the MHLW, the establishment of a unified evaluation method is needed. Consequently, the Japan Cosmetic Industry Association (JCIA) has established a task force to develop guidelines for evaluating anti-wrinkle effects in 1998. In conclusion, the JCIA would like to adopt visual and image analysis scales to evaluate the anti-wrinkle effects objectively. Generally, wrinkles are roughly classified into three groups as fine wrinkles, linear deep wrinkles and crow's feet. However, academic societies of dermatology or cosmetics have not yet established a definition of wrinkles in Japan. Thus, in advance of setting up an evaluation method, the definition of wrinkles f3r evaluation must be decided. Wrinkles are defined by the task force of the JCIA as follows; furrows that people can recognize visually and that appear on the forehead, the corners of the eyes and the backs of the neck with aging. In addition, furrows are emphasized by exposure to solar light and by dry conditions. Visual evaluation is the most sensitive method and can be applied to most types of wrinkles. However, visual evaluation is hard to express digitally as results. Besides, in the case of image analysis, comparisons of data obtained from distinct examinations can not be done, because data from image analysis are relative values. Thus, to enhance the reliability of the evaluations, the adoption of an objective scale was required. The principle of the evaluation method is to analyze images taken from silicone replicas of wrinkle areas using several parameters, such as the proportion of the wrinkle $area({\%})$, the mean depth of the wrinkles (mm), the mean depth of the deepest wrinkle (m) and the deepest point on the deepest wrinkle. Lights are shown on the skin replica from an orthogonal direction of the main orientation of the wrinkle, and the resulting shadow images are quantified by the image analysis method. To increase the precision of the data or to allow comparisons of independent examinations, a scale with furrows of several depths, 200, 400, 600, 800, and $1000{\mu}m$, is adapted in the evaluation system. I will explain the guidelines established by the JCIA in the presentation.

The impacts of guideline for digestives on physicians' prescription of GI medication Clinical practice guidelines provide benefits to physicians, patients, and researchers. It also helps doctors to make decisions in medical services. In many countries, practice guidelines lead to activities of quality improvement and are developed using evidence based methods. This research was to assess the impacts of Korean Medical Association's guideline for digestives on the change of physicians' behavior. This study was progressed as one-group pre-test post-test quasi-experimental design using health insurance claims data. The unit of analysis was institution. Data was analyzed using paired t-test for change of prescription rate before and after the distribution of practice guidelines. And the multiple regression analysis was performed to examine the independent impact of the guideline on the prescribing rate of GI medication. Prescription rates of GI medication per claim by medical institution increased significantly, 1.98%point (from 50.27% to 52.25%) and multivariate regression analysis showed significant increase in the prescription rate of GI medication after the distribution of guideline (p<0.001). In conclusion, the distribution of guideline for digestive might not have the effects on the change in provider's behavior. Furthermore, to activate the use of practice guideline, it would be necessary to educate the contents to physicians as well as to develop practice guideline.

As respiratory tract infections (RTI) account for about 60% of all antibiotic prescriptions in outpatient care setting, there are significant concerns about emerging resistance that are largely due to the excessive or inappropriate use of antibacterial agents for viral respiratory infections. This study was aimed to develop retrospective drug utilization review (DUR) program of antibiotics for RTIs using Delphi methods. Retrospective DUR criteria of antibiotics for RTIs were identified based on clinical practice guidelines and opinion of experts. Expert panel members were clinical doctors and pharmacists and Delphi method was applied by survey on 16 members of panels. The claim data from Korean Health Insurance Review & Assessment (HIRA) were used to examine trends in outpatient antibiotic prescription between Janunary to December of 2008. As results, Quality index for RTI was assessed for the claim type, antibiotics use of quantity, duration, number and cost. Antibiotic prescription rate for RTIs, Defined Daily Dose (DDD), and duration of antibiotics use were more recognized as significant quality index by experts' opinion. Use of first line agents suggested by guidelines was low and duration of antibiotics use was shorter compared to the recommendations. Antibiotics were over prescribed for RITs. However, dose and duration of antibiotics were under-used.

Purpose - This paper examines the admissibility of restitution as the legal consequence where a contract is frustrated under the Law of Reform (Frustrated Contracts) Act 1943 in comparison with Korean Civil Code (KCC). In order to provide practical guidelines and advice regarding choice of and application of law for contracting parties in international trade, the paper comparatively evaluates requirements and the scope of restitution under the Act 1943 and KCC. Design/methodology - This paper executes a comparative study to analyze whether the parties may claim restitution of money paid or non-money benefit obtained before or after the time of discharge under English law and KCC. To achieve the purpose, it focuses on the identifying characteristics of each statute, thereby providing guidelines to overcome difficulties in legal application and interpretation as to restitution as the consequence of frustration. Findings - Under English law, the benefit may be restituted according to Art 1943 or the common law rule, mistake of fact or law. Under the KCC, restitution is considered based on the principle of the obligation to recover the original obtained regardless of the time when the benefit is conferred. Whilst Act 1943 does not require careful analysis of the grounds of restitution, requirements to justify restitution according to the principle of unjust enrichment, mistake of fact or law, and the KCC should be met. Meanwhile, the KCC may provide more opportunities to award restitution because it does not require the burden of proof related to the defendant's good faith, unlike the principle of unjust enrichment. Originality/value - Where the contract is frustrated by the effect of COVID-19, one legal issue is a consequence of frustration. Therefore, this paper analyzes requirements and the scope of restitution under English law as compared with the KCC in a timely manner. It provides contracting parties with practical guidelines and advice to reduce unpredictability when they choose the governing law in a contract.
