The losses of accidents in the construction industry was significantly increased during the past decades. Therefore, the study of risk management measures in the domestic construction has become very important, and the inherent risk factors need to derive and analyze them based on the quantified method. However, most studies on the construction risk are conducted finding on the qualitative way. This study analysis the accident records from actual construction sites as a quantities study. A correlation analysis and regression analysis are adopted to identify the risk factors and develop a model. The results of this study are expected to be evolve through the accumulated effect and verification of data in the future through continuous feedback.

Recently the company is getting bigger and has many employees. Therefore, sometimes, the uniform internal marketing devices for whole employees are inappropriate because they are different demographic aspects. To find efficient internal marketing factors, this paper analyzes empirically the determinants of employee's satisfaction to their firm, by group based demographic aspects(male and female : 2 groups, ages : 3 group, employment period : 3 groups), for a insurance claim adjuster company As a result, it is found that the psychological factor has the statically significant determinant in all the 8 groups, with biggest positive coefficient in the 7 groups. Other factors, such as the organizational factor, the individual factor and spatial factor are statically significant determinant depending on the groups differently.

This study identifies various risk factors associated with activities of early construction stage, then establishes the Risk Breakdown Structure(RBS) by classifying the risks into the three groups; Common risks, risks for Earth works, and risks for Foundation works. The Common risks are identified and classified by considering various aspects of the early construction stage such as financial, political, constructional aspects, etc. The risks for Earth works and Foundation works are identified in detail by surveying technical specifications, relevant claim cases and interviewing with experts. These risks are classified based on the Wok Breakdown Structure(WBS) of the early construction stage. The WBS presented in this study classifies the works of early construction stage into four categories; excavation, sheeting works, foundation works, footing works. This study suggests a risk analysis method using fuzzy theory for construction projects. Construction risks are generally evaluated as vague linguistic value by subjective decision making. Fuzzy theory is a proper method to quantify vague conditions of construction activities. Therefore, this study utilizes fuzzy theory to analyse construction risks. The weight of risks is estimated by reflecting the interrelationship among risk factors from absolute weights obtained by fuzzy measure into the relative weights by Analytical Hierarchy Process(AHP). The interrelationship is estimated by Sugeno-fuzzy measure.

Objective: To analyze osteoporosis treatment patterns and teriparatide prescription-associated factors in Korea by using a national health insurance claims database. Methods: We utilized the Health Insurance Review & Assessment Service National Patients Sample claims database to identify patients (aged ≥50 years) with at least one osteoporosis claim (International Classification of Disease 10th revision code: M80, M81, M82) and at least one prescription for osteoporosis medication (antiresorptive agents: bisphosphonates, selective estrogen receptor modulators, denosumab, and calcitonin; bone-forming agent: teriparatide) in 2018. Demographic characteristics and healthcare utilization patterns were analyzed. Factors associated with teriparatide prescriptions were assessed using a multivariate logistic regression model. Results: Records showed that 44,815 patients were prescribed osteoporosis medications in 2018; the percentage of patients prescribed each treatment was as follows: 86.6% bisphosphonates, 13.9% selective estrogen receptor modulators, 3.1% calcitonin, 2.1% denosumab, and 0.7% teriparatide. A greater proportion of patients prescribed teriparatide were ≥75 years (53.4% vs. 33.8%) and had fractures (63.9% vs. 12.8%) compared to the same for antiresorptives (p<0.001). Patients prescribed teriparatide had higher Charlson comorbidity index values (1.2±1.3 vs. 0.9±1.2) and were more frequently hospitalized (0.8±1.3 vs. 0.1±0.5) than those prescribed antiresorptives (p<0.001). Elderly patients (≥75 years old; adjusted OR=1.66; 95% CI 1.16-2.38) and those with fractures (adjusted OR=6.23; 95% CI 4.76-8.14) were more likely to be prescribed teriparatide than antiresorptives. Conclusion: Patients prescribed teriparatide were older and more likely to have severe osteoporosis than those prescribed antiresorptives.

Recently, NFT, which is growing at a rapid pace, is gradually entering our lives. NFT is an acronym for Non-Fungible Token, a technology that allows you to claim ownership of digital data. As ownership of digital data takes over, it is showing characteristics as an investment value along with the characteristics of new technology, and it is expected to develop further in the future. In this study, we tried to analyze the intentions of users who own NFTs to purchase. Factors that can influence purchase intentions were selected and a research model was established using personal characteristics, NFT characteristics, and social characteristics. As a result of conducting an empirical study, it was found that individual innovativeness, profitability and reliability of NFT, and FOMO factors significantly influence purchase intention.

The liver is the predominant metastatic site for pancreatic cancer. However, the factors that determine the liver metastasis and the specific molecular mechanisms are still unclear. In this study, we used human pancreatic cancer cell line Hs766T to establish Hs766T-L3, a subline of Hs766T with stable liver metastatic ability. We performed RNA sequencing of Hs766T-L3 and its parental cell line Hs766T, and revealed huge differences in gene expression patterns and pathway activation between these two cell lines. We correlated the difference in pathway activation with the expression of the four core transcriptional factors including STAT1, NR2F2, GATA2, and SMAD4. Using the TCGA database, we examined the relative expression of these transcription factors (TFs) in pan-cancer and their relationship with the prognosis of the pancreatic cancer. Among these TFs, we considered GATA2 is closely involved in tumor metastasis and may serve as a potential metastatic driver. Further in vitro and in vivo experiments confirmed that GATA2-mediated transcriptional activation of Notch3 promotes the liver metastasis of Hs766T-L3, and knockdown of either GATA2 or Notch3 reduces the metastatic ability of Hs766T-L3. Therefore, we claim that GATA2 may serve as a metastatic driver of pancreatic cancer and a potential therapeutic target to treat liver metastasis of pancreatic cancer.

The purpose of this study was to analyze the claim data of Health Insurance Review & Assessment Service to determine what factors affected the length of stay in patients aged 65 and older and undergoing total knee arthroplasty due to the principal diagnosis of gonarthrosis by the type of medical institutions. As a result of making an analysis, gender, age, medical security type, severity, residential area and the number of sickbeds were identified as the factors that influenced the length of stay in each type of medical institutions. At this point in time when an increase in the elderly population triggered by population aging and another subsequent increase in medical expenses put a heavy strain on household and national economy, it's necessary to consider how to shorten the length of stay and how to ensure the efficient management of sickbeds based on the findings of this study. In addition, this study is of significance in that it could be used as basic data on quality life-care for elderly patients by the introduction of a systematic management system geared toward lessening patient burden for medical expenses.

Background: Fixed-dose combinations have the advantage of improving patient compliance, but may increase the risk of duplicate prescriptions. As the use of fixed-dose combination antihypertensives increases, it is necessary to investigate the current status of class duplication prescriptions (CDP) in patients taking fixed-dose combination antihypertensives in Korea and to identify factors associated with CDP. Methods: We conducted a retrospective observational study using nationally representative claim data. Hypertensive patients aged 20 years or older taking fixed-dose combination antihypertensives were extracted. Among these patients, patients with CDP were identified. A chi-square test was applied to determine the differences between patients with CDP and non-CDP. The associated factors of CDP were identified through multiple logistic regression. Results: Of the 74,165 patients who were prescribed fixed-dose combination antihypertensives, 426 patients (0.6%) with CDP were identified. The most common antihypertensive class associated with CDP was calcium channel blockers (194 patients, 45.5%), followed by angiotensin II receptor blockers (136 patients, 31.9%). Patients aged 75 years or older (odds ratio [OR] 1.83, 95% confidence interval [CI] 1.02-3.52), chronic kidney disease (OR 4.45, 95% CI 2.15-8.25), chronic heart failure (OR 2.71, 95% CI 1.93-3.72), coronary artery disease (OR 2.22, 95% CI 1.60-3.03) and Medical Aid/Patriots and Veterans Insurance (OR 1.49, 95% CI 1.04-2.07) were significantly associated with increased CDP. Conclusions: The factors associated with CDP were the elderly, comorbidities, and low socioeconomic status. Since CDP can result in negative clinical outcomes, active intervention by the pharmacist is warranted.

Background: There is controversy surrounding the claim that current nursing workforce policies exacerbate the geographic imbalance of nurses in Korea, but very few studies have confirmed this assertion. Therefore, this study aimed to identify factors influencing the distribution of nurses at the regional level, including variables related to nursing workforce policies. Methods: This study analyzed the distribution of 225,462 practicing nurses across 250 regions in Korea as of 2020. National statistics were collected for these 250 regions, and regression analysis was conducted. Results: Factors influencing the distribution of practicing nurses included the number of annual inpatient days, integrated nursing care service beds, public healthcare institutions, tertiary hospitals, and general hospitals. Additionally, the number of nursing graduates and healthcare institutions with nurse staffing grade 1 and 2 had an impact on nurse distribution in non-capital regions. Conclusion: To prevent exacerbating the geographic imbalance of nurses, careful decisions should be made regarding the expansion of integrated nursing care service beds. Furthermore, it is necessary to increase the number of nursing students in non-capital regions and prioritize the improvement of wages and working conditions for nurses in those areas.

The purpose of this study was to examine the role of provider practice patterns in the difference in health expenditure between the two types of patients: Health Insurance and Medical Aid type 1. The study used the outpatient claim data for all Medicaid and health insurance patients of hypertension who received medical services from 8,454 primary care physicians during the first half of 2006. The data were stratified by patient's gender and age for the two groups of patients who received care from the same physician. The dependent variables were the differences in medical expenditure per case, patient days per case and medical expenditure per patient day between Medicaid patients and health insurance patients. Empirical results showed that physician characteristics, such as physicians under age 50, greater proportion of pediatric Medicaid patients, lower proportion of new Medicaid patients and the greater number of comorbidity of Medicaid patients are associated with the greater difference between the two types of patients (i.e., greater expenditure of Medicaid patients relative to health insurance patients). This study shows that factors associated with provider practice patterns need to be taken into account in Medicaid policy.
