Currently, the permanent road traffic volume surveys under Road Act are conducted using a intrusive Automatic Vehicle Classification (AVC) equipments to classify 12 categories of vehicles. However, intrusive AVC equipment inevitably have friction with vehicles, and physical damage to sensors due to cracks in roads, plastic deformation, and road construction decreases the operation rate. As a result, accuracy and reliability in actual operation are deteriorated, and maintenance costs are also increasing. With the recent development of ITS technology, research to replace the intrusive AVC equipment is being conducted. However multiple equipments or self-built DB operations were required to classify 12 categories of vehicles. Therefore, this study attempted to prepare a method for classifying 12 categories of vehicles using vehicle specification information of the Vehicle Management Information System(VMIS), which is collected and managed in accordance with Motor Vehicle Management Act. In the future, it is expected to be used to upgrade and diversify road traffic statistics using vehicle specifications such as the introduction of a road traffic survey system using Automatic Number Plate Recognition(ANPR) and classification of eco-friendly vehicles.

This study aimed to determine foodservice and hygiene management statuses at welfare facilities catering to disabled persons by facility type to provide basic data for foodservice management guidelines. An online survey was distributed to workers at 1,984 welfare facilities for disabled persons in Korea, and 531 facilities responded, which represented a response rate of 26.8%. The survey requested general information about the facilities, facility users, meals, hygiene, and management. Statistical analyses were performed, and frequency analysis and the chi-square test were used to investigate responses by facility type. The survey results revealed that daycare centers were most common and accounted for 27.4% of responses. Residential facilities for the severely disabled and sheltered workshops accounted for 16.9% and 16.4%, respectively, and residential facilities by disability type accounted for 13.0%. The presence of dietitians at welfare facilities varied by facility type. Welfare centers for the disabled (94.7%) had the highest percentage of dietitians, followed by residential facilities for the severely disabled (87.8%). On the other hand, sheltered workshops and daycare centers for disabled persons had the lowest percentages of dietitians (10.3% and 4.1%, respectively). This study highlights the variations that exist in foodservice management across different welfare facilities for disabled persons and emphasizes the challenges faced by those responsible for managing foodservices and maintaining hygiene, particularly in large facilities with no dietitians. Therefore, we recommend tailored meal management guidelines be developed for each type of welfare facility for disabled persons.

This study analyzed the differences in the general characteristics, mental and health-related factors, eating habits, and nutrient intake of Korean male youths before and after the outbreak of the coronavirus disease 2019 (COVID-19). The data of a total of 1,231 subjects, from among the participants in the 2018 and 2020 Korea National Health and Nutrition Examination Survey (KNHANES), were analyzed. The 2020 group had fewer married members than the 2018 group. The subjects in the 2020 group weighed more (P<0.05), had a higher waist circumference (P<0.01), and showed greater weight gain (P<0.05) than the 2018 group subjects. The aerobic physical activity of the 2020 group was lower (P<0.01) compared to the 2018 group. The members of the 2020 group had higher depression scores (P<0.01), suicidal tendencies (P<0.01), and need for counseling for mental problems (P<0.05) than those of the 2018 group. The prevalence of high fasting blood sugar levels and diabetes was higher in the 2020 group compared to the 2018 group. The frequency of breakfast (P<0.01) and dining out (P<0.001) and the proportion of breakfast (P<0.01) and dinner (P<0.05) taken with the family or non-family members was lower in the 2020 group than in the 2018 group. The rate of dietary supplement intake of the 2020 group was higher than that of the 2018 group (P<0.01). There were significant differences in the protein (P<0.05), riboflavin (P<0.01), and carbohydrate (P<0.01) intakes between the two groups. These results suggest that male youths had a higher waist circumference and high levels of depression, and showed a decrease in frequency of breakfast intake and dining out after the out break COVID-19 pandemic. Therefore, nutrition and health promotion programs are urgently needed to improve mental health, other health-related factors and nutritional status of male adults that are associated with the COVID-19 pandemic.

eCall system assists traffic accident victims by connecting emergency rescue institutions with accurate accident information, helping them to identify the on-site situation in the event of a traffic accident. The purpose of this paper is to develop a Korean eCall system that reflects the requirements of domestic emergency rescue institutions and to analyze the expected effects through an integrated demonstration. The results of an integrated demonstration indicated that the communication success rate between the eCall IVS and the call center was 99.25%, and the average location information error was 1.2 m. In particular, it has been confirmed that the average location information error is less than 21.6 meters, as assessed by the Korea Communications Commission when evaluating the accuracy of domestic emergency rescue location information. When the eCall system was introduced, it was confirmed that the time from traffic accidents to hospital arrival could be shortened by 3 m 38 s for highways and 1 m 22 s for general roads. By it to traffic deaths from 2005 to 2022, it was analyzed that the number of fatalities decreased by 82,662, resulting in a reduction of approximately social costs.

The security law and security industry of Japan have a great impact on Korea. In a modern sense, there are little large disparities between the two nations in the history and development of private security. However, the way they look at private security is not the same in large part. In Japan, private security companies are highly regarded by Japanese people as organizations that guarantee their safety, owing to the efforts of private security companies themselves, the National Security Association and civic groups. Private security has especially been approved and supported since it was decided in the anticrime cabinet council in December, 2003, in line with the action plan for the realization of anticrime society to boost private security as an industry to ensure people's safety in daily routine life by curbing crimes that might pose a threat to peaceful life. Afterwards, there has been a dynamic collaboration between the Japanese police and private security in terms of education, crime prevention, disaster prevention/restoration and everyday life safety. As for Korea, the necessity of cooperation between private security and the police is increasingly stressed, and it's required to strengthen their partnership to ensure successful crime prevention in consideration of Japanese partnership cases. In Japan, the police, civic groups, the security association and security companies make every effort to satisfy Japanese people's safety needs in diverse ways and take disaster-prevention measures as well.

World Health Organization reported that heart-related diseases such as coronary artery stenoses show the highest occurrence rate which may cause heart attack. Using Computed Tomography angiography images will allow radiologists to detect and have intervention by creating 3D roadmapping of the vessels. However, it is often complex and difficult do reconstruct 3D vessel which causes very large amount of time and previous researches were studied to segment vessels more accurate automatically. Therefore, in this paper, Region Competition, Geodesic Active Contour (GAC), Multi-atlas based segmentation and Active Shape Model algorithms were applied to segment aortic root from CTA images and the results were analyzed by using mean Hausdorff distance, volume to volume measure, computational time, user-interaction and coronary ostium detection rate. As a result, Extracted 3D aortic model using GAC showed the highest accuracy but also showed highest user-interaction results. Therefore, it is important to improve automatic segmentation algorithm in future

The purpose of this study was to elucidate the effects of spiritual nursing intervention on pain and anxiety of the hospice patients. This study was devised with a quasi-experimental design using non-equivalent contrast group non-synchronized design. The data were collected during the period from July 10 to September 25 in 2000 at the general hospital in CheonJu city. The subjects were sixty-seven patients who referred the hospice service. They were assigned to two groups, 36 members of the experimental group and 30 members of the contrast group. They also did not any complication, were alert enough tobe interviewed and agree willingly to participate in this study. The tools used were Yoon's Korean Version of Brief Pain Inventory and Spielberger's State Anxiety Scale. The spiritual care intervention was carried out through Hymn, Scripture, Prayer, the therapeutic use of self over a period of three weeks. Data were analyzed by mean, standard deviation, $x^2$-test, t-test, paired t-test and Pearson's Correlation Coefficients. The results of this study were as follows: 1.The examination of the same quality showed that there were not significant differences in the general characters, disease and therapeutic characters, religional characters between the experimental group and the contrast group. 2.After the spiritual nursing intervention pain scores of the experimental group were remarkably lower than those of the contrast group(right now pain: t=-2.634, p=0.012). 3.Decreasing rate in the pain scores of the experimental group were remarkably lower than those of the contrast group(right now pain: t=5.017, p=0.000). 4. After the spiritual nursing intervention state anxiety of the experimental group were remarkably lower than those of the contrast group(t=-5.987, p=0.000). 5. A positive correlation was found between reported pain and depression following the spiritual nursing intervention. In conclusion, the hospice patients who were offered spiritual care became lower than those who were not offered spiritual care and confirmed to decrease pain. According to these results, spiritual nursing intervention can be regarded as an effective nursing intervention that relieved pain and anxiety of the hospice patients.
