Open data has a lot of economic value. Not only Korea, but many other countries are doing their best to make various policies and efforts to expand and utilize open data. However, although Korea has a large amount of data, the data is not utilized effectively. Thus, attempts to utilize those data should be made in various industries. In particular, in the fashion industry, exchange and refund problems are the most common due to unpredictable consumers. Better feedback is necessary for service providers to solve this problem. We want to solve it by showing improved images of dissatisfactions along with user reviews including consumer needs. In this paper, user reviews are analyzed on online shopping mall websites to identify consumer needs, and product attributes are defined by utilizing the attributes of K-fashion data. The users' request is defined as a dissatisfaction attribute, and labeling data with the corresponding attribute is searched. The users' request is provided to the service provider in forms of text data or attributes, as well as an image to help improve the product.

Objectives : The purpose of this review study is to identify clinical indications of Hwangryunhaedok-tang(HHT) external application and to suggest directions for future research and treatment by analyzing domestic cases applying HHT external treatment except for pharmacopuncture research. Methods : We searched 235 studies published in Korean since 2000 from four domestic databases: Oriental Medicine Advanced Searching Integrated System(OASIS), Research Information Sharing Service(RISS), Korean Traditional Knowledge Portal(KTKP), and Korean studies Information Service Systems(KISS) using keywords such as 'HTT and external use', 'HHT and external agent' 'HHT and wet dressing', or 'HHT and case'. We excluded duplicate papers, papers related to acupuncture including pharmacopuncture, or papers not related to the topic. Results : We selected and analyzed seven case reports. HHT external agent was used alone in one case, as main treatment in two cases, and as adjuvant treatment in four cases. HHT external application was applied to various skin diseases accompanied by inflammation mainly in the form of wet dressings. Conclusion : HHT external agent may be effective on various skin diseases accompanied by inflammation when applied alone or in combination with other agents according to the treatment stage. Based on this results, further studies will be needed to establish the primary clinical indication of HHT external agent.

Objectives This study aimed to analyze the medical utilization of low back pain (LBP) patients after back surgery and estimate the medical costs of Korean and Western medicine collaborative treatment, odds ratio, and hazard ratio between the two groups using the 2019 Health Insurance Review and Assessment Service-National Patient Sample (HIRA-NPS-2019). Methods Data management and descriptive analysis, logistic regression, and survival analysis were conducted for defining and estimating the LBP patients after back surgery in the NPS 2019 dataset. Results A total of 216,424 patients out of 991,189 were identified as having LBP. Among the patients with LBP, 1,734 were treated with surgery while 214,690 were not. Among those who had surgery, 937 were treated with conventional treatments only and 797 underwent Korean medicine treatments. The odds ratio of the logistic regression analysis was 0.7129, suggesting that Korean medical treatment experience group had a 28.7% lower risk of reoperation than the Western medical treatments only group. The hazard ratio of the survival analysis was 0.9145; thus, the risk probability of reoperation was estimated to be approximately 8.55% lower. The 50% risk of reoperation was 69 days (0.5044) for the conventional group, and 97 days (0.5008) for the Korean medical group in the survival analysis using the Kaplan-Meier graph. Conclusions These results could be utilized in future studies in conducting economic evaluation for estimating cost-effectiveness of Western medicine and Korean medicine treatment compared to Western medicine alone in LBP patients after back surgery in a South Korean perspective. mended and should be applied while taking the necessary precautions.

Antibiotics are used for the prevention and treatment of infections. This study aimed to investigate the patterns of dental antibiotic prescription in children and adolescents. The Health Insurance Review and Assessment Service provided data on patients who visited medical institutions. It was categorized according to year, sex, age, insurance type, dental institution, and region. Chi-square tests, Fisher's exact tests, and one-way analyses of variance were performed. Statistical analyses were performed using SAS software (ver. 9.2; SAS Institute, Cary, NC, USA). Amoxicillin and cephalosporins, the most commonly used antibiotics, accounted for approximately 96% of the prescriptions. The younger the child, the more antibiotics were prescribed for trauma, pulpitis, and dental abscesses. However, closer to adolescence, the antibiotics were primarily prescribed to manage impacted teeth and periodontal problems. Antibiotics were prescribed for 3.13 days on average. There were significant differences in the prescription rates according to age, sex, type of insurance, type of medical institution, and region (p < 0.05). This study suggested that antibiotic prescriptions should be closely monitored to ensure appropriate usage of antibiotics.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic has led to a global shortage of medical resources; therefore, we investigated whether COVID-19 impacted the quality of non-COVID-19 hospital care in Korea by comparing hospital standardized mortality rates (HSMRs) before and during the pandemic. Methods: This retrospective cohort study analyzed Korean National Health Insurance discharge claim data obtained from January to June in 2017, 2018, 2019, and 2020. Patients' in-hospital deaths were classified according to the most responsible diagnosis categories. The HSMR is calculated as the ratio of expected deaths to actual deaths. The time trend in the overall HSMR was analyzed by region and hospital type. Results: The final analysis included 2 252 824 patients. In 2020, the HSMR increased nationwide (HSMR, 99.3; 95% confidence interval [CI], 97.7 to 101.0) in comparison to 2019 (HSMR, 97.3; 95% CI, 95.8 to 98.8). In the COVID-19 pandemic zone, the HSMR increased significantly in 2020 (HSMR, 112.7; 95% CI, 107.0 to 118.7) compared to 2019 (HSMR, 101.7; 95% CI, 96.9 to 106.6). The HSMR in all general hospitals increased significantly in 2020 (HSMR, 106.4; 95% CI, 104.3 to 108.5) compared to 2019 (HSMR, 100.3; 95% CI, 98.4 to 102.2). Hospitals participating in the COVID-19 response had a lower HSMR (HSMR, 95.6; 95% CI, 93.9 to 97.4) than hospitals not participating in the COVID-19 response (HSMR, 124.3; 95% CI, 119.3 to 129.4). Conclusions: This study suggests that the COVID-19 pandemic may have negatively impacted the quality of care in hospitals, especially general hospitals with relatively few beds. In light of the COVID-19 pandemic, it is necessary to prevent excessive workloads in hospitals and to properly employ and coordinate the workforce.

To protect people and the environment from environmental radiation, the Act on Protective Action Guidelines against Radiation in the Natural Environment was formulated in Korea in 2011. This law regulates matters related to radiation safety that can be encountered in life. In accordance with this law, radiation monitoring equipment is operated at major airports and ports across the country, ensuring radiation monitoring of imported cargo. Currently, six ministries conduct radiation monitoring of imported cargo: the Nuclear Safety and Security Commission; the Korea Customs Service; the Ministry of Food and Drug Safety; the Ministry of Environment; the Ministry of Agriculture, Food and Rural Affairs; and the Korea Forest Service. Each ministry designates the relevant cargo items for radiation monitoring. The objective of this study was to comprehensively review the Korean radiation monitoring system for imported cargo and identify the areas and scopes of improvement. This paper also proposes a new law and an integrated supervision plan, which involves establishing a dedicated department to enhance the efficiency and professionalism of the national radiation monitoring system for imported cargo. The review will contribute to the development of a more sophisticated national radiation monitoring system for imported cargo.

This study evaluates the potential by Chines region for entry of Korean logistics companies and retailers. The variables affecting e-commerce business and retail sales concerning the Chinese omni-channel market were extracted from a thorough literature review. Empirical analyses for variables based on 31 regions in China were performed. Results show that e-commerce is affected by disposable income and internet traffic and that retail sales are affected by urban and rural population, GRDP and urbanization. In addition, we performed variance decomposition analysis in order to estimate responses of logistics GDP(transport, storage and communication) and the number of Chinese mobile users. Exogenous shocks to logistics GDP and the number of mobile phone users play a strong role in explaining the forecast error of express service variance over time. Based on our results, we suggest 7 potential regions(Guangdong, Jiangsu, Zhejiang, Beijing, Shanghai, Liaoning and Shandong) as well as managerial implications for entry into China for logistics companies and retailers.

As face-to-face communication has become difficult due to the COVID-19 pandemic, studies have been conducted to understand the impact of non-face-to-face communication, but there is a lack of research that examines this through messenger application reviews. This study aims to identify the impact of the pandemic through Latent Dirichlet Allocation (LDA) topic modeling by collecting review data of 메신저 applications in the Google Play Store and suggest service strategies accordingly. The study categorized the data based on when the pandemic started and the ratings given by users. The analysis showed that messenger is mainly used by middle-aged and older people, and that family communication increased after the pandemic. Users expressed frustration with the application's updates and found it difficult to adapt to the changes. This calls for a development approach that adjusts the frequency of updates and actively listens to user feedback. Also, providing an intuitive and simple user interface (UI) is expected to improve user satisfaction.

This paper attempts to review of recent development of ASEAN financial integration and to evaluate it and predict its future aspect. For this purpose, we first examine the historic aspect of ASEAN financial integration such as ASEAN financial service open agreement or ASEAN capital market forum report and currently agreed integration plan. In addition, we study the development stages of ASEAM member countries in terms of its economic size or income level. Finally, we look at the financial market and institutional aspect of ASEAN member countries and the recent development of global financial market. From these analyses, we find several important facts. First, it is true that ASEAN, in general, will enjoy the effect of expanding regional investment and improving the quality of financial service through the financial integration. We think that its long term benefit is too large for ASEAN member states to avoid. Second, as a result, it is certain that ASEAN will corporate further to make its financial market to be integrated in the future. Third, however, despite these benefits and continuing efforts, we expect that it will be very difficult for ASEAN to reach a stage of financial integration as suggested in the Blueprint of ASEAN Economic Community by the year of 2015. The large difference among member states in term of economic and financial development will not allow for them to reach a single goal within a short time. Instead, we expect the following scenario for the integration process will hold. First, ASEAN will reach an agreement on the institutional framework by 2015 and afterwards, slowly the markets will begin to integrate. Second, at the earlier stage, not all but some countries will start the integration process. We expect that the financial market of ASEAN 5 will first be integrated and other 5 will join to it later.
