Recently, there has been an increase in the research and development of automated vehicles worldwide. Research focused on automated vehicles in Korea is steadily progressing as a national R&D project. Since automated driving technology comprises diverse technology fields, it is necessary to identify the current position of the research. In this study, we propose a methodology for analyzing research trends using the NTIS data. In addition, we review the effectiveness of the currently developed research trend methodology by deriving primary keywords and major topics using the proposed method. We expect that the methodology developed in this study can be applied to identify and analyze future automated vehicle research trends.

Key Performance Indicators (KPIs) are the criteria of measuring project performance in order to attain construction excellence. Previous researchers have examined the abstract concept of success for general new construction and identified its relationship with the factors of success. In fact, most buildings exist to satisfy the needs of people. With the passing of time and change in technology, buildings have to be maintained and renovated in order to continue functioning properly for the benefits of users. Therefore, criteria and factors of success have increasingly attracted the attention of both researchers and practitioners, especially in cities where buildings become ageing. However, the topic of project success for maintenance projects is less discussed in previous research, and project participants, including maintenance surveyors should be able to identify the success measurement and its associated factors for performance improvement. This study fills the research gap by investigating the criteria and factors of success for maintenance projects. It first provides a summary of the literature review on the criteria and factors of success for construction projects. An empirical study has also been carried out with ten practitioners in Hong Kong to further identify the criteria and factors critical for the success of maintenance projects in practice. While most criteria and factors of success for new construction projects are also applicable to maintenance projects, participants in maintenance projects believe that effective communication is in particular important to provide quality service to the end-users.

Objectives: To investigate and analyze the assessment indicators and tools used in clinical practice to assess Korean medicine (KM) treatment for infertility, and to establish a basis for assessment tools to diagnose and assess infertility. Methods: Relevant studies published until March 2023 were extracted from Pubmed, Research Information Sharing Service, and National Digital Science Library databases. Results: Sixty-four studies comprising 4,105 patients were included. We investigated pregnancy outcomes, and assessed pregnancy- and childbirth-related factors, overall health, reproductive health, and mental health. Pregnancy result was most common primary outcome. Ongoing pregnancy, stillbirth, miscarriage, and ectopic pregnancy rates were suggested as indicators of pregnancy and childbirth-related assessment. Overall health was most commonly assessed with Likert and Visual analogue scale (VAS). Among reproductive health variables, menstrual history was most frequently assessed. Moreover, indicators such as reproductive function, sexual intercourse, and gynecological disease were assessed. The Infertility Stress Scale and the Fertility Quality of Life tool (FertiQoL) were used to assess mental health. Conclusions: Subjective scales and objective assessment tools, such as the Likert scale and blood tests/ultrasonography, respectively, are used to assess KM infertility treatment. Inconsistent assessment tools make quantitative analyses more challenging. The development of a standardized mental and physical function assessment questionnaire with confirmed reliability and validity ensure the effectiveness of KM infertility treatment, and promote future studies on infertility treatment.

Purpose: This study aims to provide basic data for the future construction plans of the Infectious Disease Hospitals by analyzing the area composition and required room ratios in the wards and ICU of currently under-construction infectious disease hospitals. Methods: 3 Methods have been used in this paper. 1) This study conducted a literature review on major considerations and related guidelines for hospitals specializing in infectious diseases using existing data. 2) Based on the objects and activities of the hospital space, zones and areas were set for each department according to infection control. 3) Based on the established zones and areas, basic plan drawings of three hospitals specializing in infectious diseases currently under construction were collected and architectural drawing analysis was performed. Results: 1) Infectious Diseases Hospital must have a spatial organization that can accommodate patient isolation, infection control, efficiency of medical service, and changes. 2) Zones for infection control are divided into negative pressure and non-negative pressure zones based on airborne precaution isolation. It is divided into clean and contaminated zone according to class of cleanliness by Aseptic technique. Areas are classified by objects (patients, healthcare workers, supplies) and activities (access, medical treatment, support), and a system for organizing space is established based on this. 3) By analyzing the area composition of each departmental area, each required room, and each required space in the wards and intensive care units, it provides basic data for the spatial organization for architectural planning of the infectious disease hospital. Implication: It can be used as basic data when planning related facilities by analyzing the characteristics of the space plan of the required room according to the relationship between activities, movement lines, and operation plans based on user behavior.

Background & Objectives: Fixed-dose combinations (FDCs) offer advantages in adherence and cost-effectiveness compared to free combinations (FCs), but they can also complicate the prescribing process, potentially leading to therapeutic duplication (TD). This study aimed to identify the prescribing patterns of FDCs for dyslipidemia and investigate their associated risk of TD. Methods: This was a retrospective cohort study involving drugs that included statins, using Health Insurance Review & Assessment Service-National Patient Sample (HIRA-NPS) data from 2018. The unit of analysis was a prescription claim. The primary outcome was TD. The risk ratio of TD was calculated and adjusted for patient, prescriber, and the number of cardiovascular drugs prescribed using a multivariable Poisson model. Results: Our study included 252,797 FDC prescriptions and 515,666 FC prescriptions. Of the FDC group, 46.52% were male patients and 56.21% were aged 41 to 65. Ezetimibe was included in 71.61% of the FDC group, but only 0.25% of the FC group. TD occurred in 0.18% of the FDC group, and the adjusted risk ratio of TD in FDC prescriptions compared to FC was 6. 44 (95% CI 5. 30-7. 82). Conclusions: Prescribing FDCs for dyslipidemia was associated with a higher risk of TD compared to free combinations. Despite the relatively low absolute prevalence of TD, the findings underline the necessity for strategies to mitigate this risk when prescribing FDCs for dyslipidemia. Our study suggests the potential utility of Clinical Decision Support Systems and standardizing nomenclature in reducing medication errors, providing valuable insights for clinical practice and future research.

For meteorological applications, meaningful results must be derived and provided within time and resource limits. Forecasts through numerous historical data are time-consuming and still have resource limitations in the case of disaster safety-related analyses/predictions such as local typhoon forecasts. Suitable forecasts should be provided without any problems caused by limited physical environmental conditions and when results are to be drawn under time constraints, such as typhoon forecasts and forecast services for flooded areas by road. In this paper, we analyze the application of weather and climate forecasting to provide a suitable forecasting service in both temporal and resource conditions. Through the analysis of execution time according to mesh sizes, it was confirmed that a mesh adjustment can cope with the case of the temporal constraint. In addition, by analyzing the execution time through memory resource control, we confirmed the minimum resource condition that does not affect the performance and the resource usage pattern of the application through the swap and mlock analysis.

A Science DeMilitarized Zone (DMZ) is an optimized network technology tailored to research data nature. The Science DMZ guarantees end-to-end network performance by forming a closed research network without redundant networking and security devices for the authorized researchers. Data Transfer Node (DTN) is an essential component for the high performance and security of the Science DMZ, since only transfer functions of research data are allowed to the DTN without any security- and performance-threatening functions such as commercial internet service. Current Science DMZ requires per-user DTN server installation which turns out a scalability limitation of the networks in terms of management overhead, entry barrier of the user, and networks-wise CAPEX. In order to relax the aforementioned scalability issues, this paper suggests a centralized DTN design where end users in a group can share the centralized DTN. We evaluate the effectiveness of the suggested sharable DTN design by comparing CAPEX against to that of current design with respect to the diverse network load and the state-of-the-art computing machine.

Purpose: This study aimed to comprehensively analyze the recent revision of the Outcome and Assessment Information Set (OASIS)-D to version E in the United States to identify the most recent trends in home health care and provide suggestions for implementing home health care in Korea. Methods: This study is a comprehensive literature review. We compared all items in OASIS-D and OASIS-E and identified the most significant changes. Additionally, we have discussed the context in depth. Results: The addition of items related to health literacy and medication reconciliation, strengthening assessment in the cognitive and mood domains, and improving items related to pain assessment were identified. These major revisions resulted from a greater emphasis in the healthcare field on social determinants of health. Additionally, the COVID-19 outbreak highlighted the importance of monitoring and managing the symptoms of home care patients in the community. Conclusion: The key items of the OASIS amendment and their background analysis proposed in this study could serve as a cornerstone for the revision of home health care assessment tools or the development of systematic common assessment tools in Korea.

Background: Gastrointestinal (GI) drugs are often co-prescribed with other medications to prevent GI complications. This study aimed to evaluate the prescribing pattern of potentially unnecessary GI drugs in patients with acute cystitis who were prescribed oral antibiotics and investigate the influencing factors affecting this. Methods: We identified female patients ≥20 years with acute cystitis who visited the outpatient clinic and were prescribed oral antibiotics between July and December by analyzing Health Insurance Review and Assessment Service (HIRA)-National Patients Sample (NPS)-2019 data. Patients with no prior history of GI disorders within 180 days prior to acute cystitis, excluding or including the date of diagnosis of acute cystitis, were selected (Group A and B). Multiple logistic regression analysis was performed to estimate the factors affecting the prescription of potentially unnecessary GI drugs. Results: A total of 1,544 in Group A and 552 patients in Group B were included for the final analysis. Potentially unnecessary GI drugs were prescribed in 1,176 patients in Group A (76.2%) and 231 patients in Group B (41.8%). Third generation cephalosporines and sulfonamides showed the lower odds ratio for prescribing GI drugs than penicillins. Prescribers from Urology clinics showed more than twice odds ratio for the prescription of GI drugs compared to prescribers from internal medicine clinics. Conclusion: The results of this study showed that potentially unnecessary GI drug prescriptions for patients with acute cystitis were high in South Korea. The positive risk factors affecting the prescription of unnecessary GIs were not patient-related factor but healthcare facility and prescriber-related factors.
