단기 마음챙김기반 집단상담이 마음챙김과 스트레스에 미치는 영향

This study aimed to examine the effects of short-term mindfulness-based group counseling on mindfulness and stress. To achieve this, a short-term mindfulness-based group counseling program was conducted for the general public, and its effects on mindfulness and stress were investigated. Participants were recruited from the Busan area, and a total of 17 individuals participated in the experiment. Among them, 8 were assigned to the experimental group, while 9 were assigned to the control group. The participants in the experimental group underwent short-term mindfulness-based group counseling for five weeks, with one session per week, each lasting two hours. For data collection, a pre-test was conducted before the group counseling for both the experimental and control groups, followed by a post-test after the counseling, and a follow-up test five weeks after the completion of the group counseling. To measure changes in mindfulness, Park Seong-hyun's mindfulness scale was used, and to measure changes in stress, the psychosocial stress scale was employed. The collected data were analyzed using the generalized estimating equations, a non-parametric statistical method. The results showed that while the changes in mindfulness due to the short-term mindfulness-based group counseling were not significant, there was a significant improvement in stress levels. Finally, implications of the findings were presented.

Feasibility of Establishing a Stroke Care System through the Acute Stroke Hotline in Busan Metropolitan Area

Background: The importance of establishing a regional stroke safety net for the treatment of acute stroke is increasingly emphasized. In this study, we analyzed effectiveness of transferring the suspected acute ischemic stroke (AIS) patients through the 1899-0215 hotline system from 119 ambulances and nearby hospitals.Methods: From July 2015 to July 2022, we analyzed data from 632 suspected acute stroke patients through the hotline. Furthermore, we investigated the proportion of patients in the target population who were eligible for reperfusion therapy and compared cases transferred by 119 emergency services (EMS) with those transferred from nearby hospitals.Results: Six hundred thirty-two suspected acute stroke patients were transferred to our stroke center through the 1899-0215 hotline system. The accuracy of diagnosing acute stroke among transferred patients is 81.0% for 119 EMS and 80.5% for cases transferred from nearby hospitals. Of the 200 patients transferred from hospitals, they were transferred from 47 nearby hospitals with an average transfer distance of 38.2 km and an average transfer time of 65 minutes. Among 291 patients diagnosed with AIS, The onset-to-door time was significantly shorter (<i>p</i><0.01) for patients transferred by 119 EMS. The proportion of patients who received reperfusion therapy was significantly higher (<i>p</i><0.01) for those transferred by 119 EMS.Conclusions: The hotline service will become a useful tool for establishing a regional stroke network in the Busan area, and its effectiveness will be particularly useful for 119 EMS. Measures are needed in the Busan metropolitan region to ensure the speediness of transferring acute stroke patients between hospitals.

Changes in Sensitization Rate to Inhalation Allergy in Busan Area Over Past 40 Years

Background and Objectives This study analyzed skin prick tests conducted on respiratory allergy patients in the Busan area for a 40-year period and estimated future changes in inhaled allergens.Subjects and Method This study conducted a retrospective analysis of patients who underwent skin prick tests for respiratory allergies at two hospitals. We analyzed 5942 test results out of the total tests of 6174 recorded from 1982 to 2021.Results For over 40 years, the main inhalant allergens in the Busan area, including house dust mites (HDM), pollen, have been found to be similar to those in other regions. The sensitization rate of HDM was very high, around 50%-60%, in the early 1990s and the early 2010s, and it showed a gradual increase over time. The sensitization rate of pollen were high at 10- year cycles. The sensitization rate of tree pollens showed a decreasing trend after reaching its peak in the late 1980s, but has been steadily increasing since the 2010s, with a sharp rise (over 25%) observed in 2019-2020. The sensitivity to weed and grass pollens was relatively high in the late 1990s and late 2000s, and exhibited a declining trend since. Among the animal allergens, the sensitization rate of cat allergen was the highest (45%).Conclusion We identified high rates of sensitization to house dust mites and tree pollens, and age-related changes over time. With the increasing prevalence of pet ownership, further research is necessary to monitor sensitization changes. Additionally, due to climate change, continuous monitoring of allergen sensitization rates to pollens and molds is called for.

Seasonal variations of dissolved rare earth elements and anthropogenic gadolinium in the highly urbanized river basin, Busan, Korea

Anthropogenic gadolinium (Gdanth) has been reported in rivers as a result of magnetic resonance imaging. We collected seasonal water samples from the Suyeong River Basin, to investigate seasonal variations in dissolved rare earth elements (REEs) and Gdanth in highly urbanized areas. The post-Archean Australian shale-normalized REE patterns indicate a significant influence of terrestrial source inputs during the summer. Although higher concentrations of dissolved REEs were measured in summer than in winter, the Gdanth concentrations exhibited similar levels. During winter, the concentrations of Gdanth showed conservative mixing trends downstream of the wastewater treatment plant (WWTP), whereas no clear trend was observed in summer. Moreover, the estimated daily discharge of Gdanth accounts for approximately 11–22% of the number of MRI tests performed, when the WWTP treats only 6% of Busan area size. Our results suggests that the elevated Gdanth level in the highly urbanized river basin is a major concern.

Design of Vessel Data Lakehouse with Big Data and AI Analysis Technology for Vessel Monitoring System

The amount of data in the maritime domain is rapidly increasing due to the increase in devices that can collect marine information, such as sensors, buoys, ships, and satellites. Maritime data is growing at an unprecedented rate, with terabytes of marine data being collected every month and petabytes of data already being made public. Heterogeneous marine data collected through various devices can be used in various fields such as environmental protection, defect prediction, transportation route optimization, and energy efficiency. However, it is difficult to manage vessel related data due to high heterogeneity of such marine big data. Additionally, due to the high heterogeneity of these data sources and some of the challenges associated with big data, such applications are still underdeveloped and fragmented. In this paper, we propose the Vessel Data Lakehouse architecture consisting of the Vessel Data Lake layer that can handle marine big data, the Vessel Data Warehouse layer that supports marine big data processing and AI, and the Vessel Application Services layer that supports marine application services. Our proposed a Vessel Data Lakehouse that can efficiently manage heterogeneous vessel related data. It can be integrated and managed at low cost by structuring various types of heterogeneous data using an open source-based big data framework. In addition, various types of vessel big data stored in the Data Lakehouse can be directly utilized in various types of vessel analysis services. In this paper, we present an actual use case of a vessel analysis service in a Vessel Data Lakehouse by using AIS data in Busan area.
