  • Purpose - This is an exploratory study that aims to apply text mining techniques, which computationally extracts words from the large-scale text data, to legal documents to quantify trade claim contents and enables statistical analysis. Design/methodology - This is designed to verify the validity of the application of text mining techniques as a quantitative methodology for trade claim studies, that have relied mainly on a qualitative approach. The subjects are 81 cases of arbitration and court judgments from China published on the website of the UNCITRAL where the CISG was applied. Validation is performed by comparing the manually analyzed result with the automatically analyzed result. The manual analysis result is the cluster analysis wherein the researcher reads and codes the case. The automatic analysis result is an analysis applying text mining techniques to the result of the cluster analysis. Topic modeling and semantic network analysis are applied for the statistical approach. Findings - Results show that the results of cluster analysis and text mining results are consistent with each other and the internal validity is confirmed. And the degree centrality of words that play a key role in the topic is high as the between centrality of words that are useful for grasping the topic and the eigenvector centrality of the important words in the topic is high. This indicates that text mining techniques can be applied to research on content analysis of trade claims for statistical analysis. Originality/value - Firstly, the validity of the text mining technique in the study of trade claim cases is confirmed. Prior studies on trade claims have relied on traditional approach. Secondly, this study has an originality in that it is an attempt to quantitatively study the trade claim cases, whereas prior trade claim cases were mainly studied via qualitative methods. Lastly, this study shows that the use of the text mining can lower the barrier for acquiring information from a large amount of digitalized text.

  • In many non-life insurance applications past data are given in a form known as the run-off triangle. Smoothing such data using parametric crisp regression models has long served as the basis of estimating future claim amounts and the reserves set aside to protect the insurer from future losses. In this article a fuzzy counterpart of the Hoerl curve, a well-known claim reserving regression model, is proposed to analyze the past claim data and to determine the reserves. The fuzzy Hoerl curve is more flexible and general than the one considered in the previous fuzzy literature in that it includes a categorical variable with multiple explanatory variables, which requires the development of the fuzzy analysis of covariance, or fuzzy ANCOVA. Using an actual insurance run-off claim data we show that the suggested fuzzy Hoerl curve based on the fuzzy ANCOVA gives reasonable claim reserves without stringent assumptions needed for the traditional regression approach in claim reserving.

  • Although the order of Design-Build is being expanded by increasing construction scale and demanding hybrid function, the suitable regulation of the contracts is not settled. Design-Build is way by government because there are big construction of much government leading in contract relation high position occupy. So, case that prebendary's claim institution develops by litigation is very rare. But, recently Design-Build is magnified. So, these dispute factors is becoming visualization gradually. The contract system is needed to be consistent by international standard to deal with the problem. This study suggests the useful solutions in detail concerned with the main factor of change order claim by each Design-Build phases through practical sorting and analysis of the causes of Change Order-Claim.

  • In recent years, the accidents in construction projects are continuously increasing due to their complexity and variety. However, few studies have been conducted regarding the risk prediction model and the database of risk assessment in construction projects. To address of these issues, the objective of this study is to analyze the accident causes by using insured claim payouts of insurance companies. First, the descriptive analysis of accidents causes is conducted according to scheduling rate, season, and total construction costs. Second, the correlation analysis is conducted between accidents causes and total construction costs. In the future, the risk assessment model can be developed to quantify the accident causes in construction projects to estimate claim payouts of insurance companies.

  • 클레임의 발생원인과 예방에 대하여 많은 연구들이 수행되어 왔으나, 개선방안 혹은 제도개선, 대응방안 등에 대한 연구가 대부분이었다. 특히, 잠재되어 있는 클레임에 대한 구체적인 내용들을 정리하고, 예방을 위한 실무적인 연구는 미흡한 실정이다. 그러므로 향후 발생할 수 있는 클레임에 대해, 그 중 설계단계에서 잠재될 가능성이 큰 원인들을 사전에 검토 및 재확인하여 클레임을 예방할 수 있는 수단이 부족하다. 본 연구에서는, 클레임이 발생되는 시기가 대부분 시공단계이지만 클레임의 원인은 설계단계에서 발생하는 점에 착안하여, 설계단계에서 잠재된 클레임 예방을 위하여 설계단계의 설계서 등을 포함한 계약문서를 중심으로 연구를 수행하였다. 클레임의 근거서류를 준비하고, 관련법규의 적용규정을 확인하면서 클레임 발생원인을 짚어볼 수 있는 체크리스트를 개발하였다.

  • Purpose - This study is designed to provide new insights on trade claim management by typifying trade claims from a relational perspective, which defines trade as an organic combination that exchanges relationships based on a mutual goal instead of conflicts between obligations and rights of the contracting parties. Design/methodology - This is a phenomenological study that aims to typify trade claims based on a relational perspective and extract implications for trade claim management. The research procedures of this study are as follows. First, international commercial dispute cases applying the CISG are collected. Second, the cases collected are quantified through content analysis. The variables for quantification are developed based on a relationship perspective. Third, cluster analysis is conducted on coded data to typify cases. And finally, this study compares the characteristics of each type using analysis of variance and suggests implications for the strategic management of trade claims from a relational perspective. Findings - Results show that trade claims are divided into four clusters, depending on whether flexibility is accepted or not and which party violates mutuality. There is also a difference between the claimant and the cause of the claim, according to the cluster. Based on the results, this study suggests that the buyer and the seller should employ different strategies depending on the type of trade claim and presents proposals for strategic claim management. Originality/value - Firstly, this study extends the theoretical discussion on trade claims by applying relational contract theory. Prior studies on trade claims have been primarily based on traditional contract theory. The second is to analyze trade claims quantitatively. Prior case studies on trade claims have mainly relied on qualitative research. Finally, the study contributes to international commercial practice by typifying trade claims and presenting options for strategic management.

  • 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.

  • This study conducted a comparative analysis of awareness level of review standards, continuing education, and awareness about the need for speciality and educational courses in order to improve quality of Korean health insurance review work and to present directions for policies of personnel development and continuing education to smoothly perform hospital's insurance claim work and Agency's review work. The analysis unit of the study is individuals, and survey was conducted among hospital's claim officers and Agency' review officers by distributing questionnaires. The major results of the study are as follows: First, it is found that hospital's claim officers and Agency's review officers have conflicting awareness about review standards; more Agency's review officers think that current review standards are universal and reasonable, while more hospital's claim officers believe that they need to be revised. Especially, hospital's claim officers replied that it is possible that review results can differ according to government's policies. Second, there is no significant difference between the two groups in the opinion that there are individual differences in awareness level of review standard. In particular, both groups share the opinion that review results can differ according to officer's interpretation of review standards. Third, Both review officer groups feel the need for further training and continuing education. Fourth, there is no difference between the two groups in the opinion that both groups members should be educated in review related educational institutions. However, while 81.5% of Agency's review officers the education should be offered at the Agency, only 45.2% of hospital's claim officers agreed to it. Fifth, both review personnel do not show any difference in awareness of needed experience to successfully perform review work; both groups replied that three to four years experience is necessary to smoothly perform claim work and review work. This study was tried in order to search for directions to improve Korean insurance review work in quality rather than to explore characteristics themselves of individual factors. In this sense, this study presupposed an intention that the educational subjects for further training and continuing education for the two groups should be the same in order to narrow the awareness gap between hospital's claim officers and Agency's review officers. Thus, this study suggests that it is desirable to offer beginner courses at junior colleges or in undergraduate courses and advanced courses in professional graduate school for six to twelve months. In that a comparison of awareness level of hospital's claim officers and Agency's review officers who are actually in practice should precede appropriate presentation of directions for the qualitative improvement of insurance review work in Korea, the significance of this study lies in comparatively analyzing the awareness level of hospital's claim officers and Agency's review officers and in presenting the establishment of future further training and continuing education.

  • 건설 프로젝트의 특성 상, 예측하기 어려운 리스크 인자에 노출되기 쉽고, 다양한 이해관계자들이 함께 동일 프로젝트를 수행하는 과정에서 발생하는 분쟁이 주요 리스크 인자로 인식된다. 다양한 분쟁은 주로 클레임 제기, 조정, 중재, 그리고 소송으로 나타나며 막대한 비용과 시간의 손실을 초래할 수 있다. 따라서 국내 건설기업의 건설 프로젝트 수행과정에서 발생하는 클레임, 분쟁의 유형과 원인을 도출하고, 각 원인의 영향도 분석을 통해 클레임, 분쟁관리에 대한 적극적인 대비가 필요하다. 본 연구는 국내 건설프로젝트에서 발생한 클레임, 분쟁 판례를 수집하여 유형과 원인에 따른 빈도와 영향도를 정량화 하고, 중요도 분석을 통해 주요 클레임 원인을 도출하였다. 도출된 주요 클레임 원인은 공사변경, 상대방의 부당한 행위, 공사 지연에 관한 클레임으로 해당 클레임 원인이 발생할 경우 클레임 비용에 대한 예측을 회귀 모형화 하였다. 주요 클레임 원인별 영향도 예측 결과 공사변경의 경우 전체공사비의 16.1%, 상대방의 부당한 행위는 전체공사비의 5.7%, 공사 지연은 전체공사비의 2.7%로 발생하는 것으로 분석되었다. 본 연구결과를 통해 국내 건설산업의 주요 클레임 요인을 도출하고, 클레임 비용을 예측함으로써 보다 적극적인 클레임 대비에 활용 될 수 있도록 하였고, 더 나아가 국내 건설기업의 프로젝트 관리 역량 평가 및 향상에 기여하고자 하였다.

  • As various stakeholders are involved in construction projects, disputes between the parties are more likely to occur, which is a very important issue for the participants in the projects. Claims in construction projects, however, are very complex and thus difficult to manage. In particular, as the cause of a claim in the preceding stage that has not been resolved in a timely manner has an effect on the cause of a claim in the following stage, it is difficult to find a point of compromise regarding a claim caused by the relationship between the causes that occur in the preceding and following stages. In this regard, this study sought to examine the rules for the generation of change order claims, which occur most frequently among the construction claims, and thus to select the key management targets through the analysis of the relationship between the causes of claims arising in the preceding and following stages for the efficient management of claims. It is expected that the use of rules for the generation of change order claims as well as of representative and similar cases will help the construction practitioners in judging claims, considering the relationships among the causes of the claims. Meanwhile, in this study, association analysis was conducted regarding the causes of the occurrence of change order claims in a design-build delivery method, and therefore, it is necessary to verify the effectiveness of the method when applied to other delivery methods.
