  • An autonomous driving system based on a precise digital map is developed. The system is implemented to the Hyundai's Tucsan fuel cell car, which has a camera, smart cruise control (SCC) and Blind spot detection (BSD) radars, 4-Layer LiDARs, and a standard GPS module. The precise digital map has various information such as lanes, speed bumps, crosswalks and land marks, etc. They can be distinguished as lane-level. The system fuses sensed data around the vehicle for localization and estimates the vehicle's location in the precise map. Objects around the vehicle are detected by the sensor fusion system. Collision threat assessment is performed by detecting dangerous vehicles on the precise map. When an obstacle is on the driving path, the system estimates time to collision and slow down the speed. The vehicle has driven autonomously in the Hyundai-Kia Namyang Research Center.

  • The purpose of this study is to grasp foreign worker's industrial safety and health state, which find out the improvement to secure the basic safety net for foreign workers. We have investigated 2,050 workers through direct interviews during the period from April 12, 2010 to May 31, 2010. And the result of analysis, foreign worker's daily average working time is 10.6 hours(40.8% workers in total work 10~12 hours), the extent of exposure to harmful and dangerous working environment is 'the position which cause pain in neck, waist, hands, shoulders, legs'(69.3%), 'repetitive hands and arms movement'(66.1%). It showed 'experience of accident damage or disease related work'(27.3%), 'never apply for industrial accident compensation' is revealed high at 73%. As a result of completing a safety health education for a year, it showed 'never educated'(40.2%), 'the institute that foreign workers have used for help and advice is the foreign worker's support center'(61.9%) Thus, hiring foreign workers in the company are small in site, the environment is too harmful and dangerous. In addition, no safety and health managers, legally blind spot located in the health and safety, because it is an urgent meet for these measures to improve.

  • Recently, it has been argued that it is necessary to attract foreign patients outside domestic insurers and to allow foreign doctors to treat in domestic hospitals in order to develop the insurance industry and revitalize the medical industry. Currently, large medical institutions in Korea are attracting foreign patients in connection with foreign insurance companies. It is desirable to increase the number of overseas patients who want excellent medical services in Korea, and to provide opportunities for domestic insurance companies to attract overseas patients by expanding job creation through a revitalization of the medical industry. Therefore, this study suggests the development direction for insurers who aim to attract foreign patients through the side effects of attracting foreign patients in accordance with the Financial Services Commission's plan to strengthen the competitiveness of the financial industry. In addition, this study intends to contribute to the strengthening of the competitiveness of attracting foreign patients, through domestic insurance business, to the insurance direct payment market for overseas patients using domestic medical institutions that are concentrated in foreign insurance companies and in the blind spot of domestic law application.

  • Purpose: This study was done to explore the lived experiences in older Korean women with early stage of Parkinson's disease. The research question was "What is the meaning and nature of the older women's experiences who were diagnosed with Parkinson's disease?" Methods: In this study, we adopted van Manen's hermeneutic phenomenological approach to find the lived experiences of older women diagnosed with Parkinson's disease. Six older women diagnosed with Parkinson's disease within five years participated, and data were collected through in-depth interviews. Results: Five fundamental lifeworld themes and seven subthemes emerged from the data. The first theme of corporeality had three subthemes: 'being shocked by an unexpected diagnosis', 'fewer things can be done due to the illness' and 'lost my prettiness'. The second theme representing relationality was 'hiding the illness because of others' whispering'. The temporality theme was 'fear of symptom aggravation'. The spatiality theme was 'being placed in a blind spot of information'. The last existential theme of material had 'obsession with drugs'. Conclusion: The results of this study provide an in-depth understanding of older womens experiences of living with Parkinson's disease. The findings can help develop interventions specific to these group of women to provide sufficient emotional support and accurate information.

  • Objectives: This study aimed to assess the relationship between dental care needs and dental service use in Korean elderly. Methods: Using the sixth Korea National Health and Nutrition Examination Survey, from 22,948 individuals, 1,572 (male 701, female 871) elderly individuals aged above 65 years were included in the study. All analyses were stratified by sex. Results: In males, the group with subjective needs was 3.74 (95% confidence interval [CI]: 2.58-5.41) times more likely to use dental services than the group without subjective needs. For females, the group with subjective needs was 2.17 (95% CI: 1.57-2.98 ) times more likely to use dental services than the group without subjective needs. Conclusions: To conclude, the elderly with symptoms, used the dental services for pain relief and functional recovery. Fundamental efforts to improve oral health are needed, such as providing treatment, prevention and educational services, besides efforts to provide treatment-oriented dental services. Further research is needed for the middle and elderly individuals who are in the blind spot of the existing policy.

  • Weak over-the-horizon perception and blind spot are the main problems in intelligent connected vehicles (ICVs). In this paper, a V2V image transmission-based road condition warning method is proposed to solve them. The encoded road emergency images which are collected by the ICV are transmitted to the on-board unit (OBU) through Ethernet. The OBU broadcasts the fragmented image information including location and clock of the vehicle to other OBUs. To satisfy the channel quality of the V2X communication in different times, the optimal fragment length is selected by the OBU to process the image information. Then, according to the position and clock information of the remote vehicles, OBU of the receiver selects valid messages to decode the image information which will help the receiver to extend the perceptual field. The experimental results show that our method has an average packet loss rate of 0.5%. The transmission delay is about 51.59 ms in low-speed driving scenarios, which can provide drivers with timely and reliable warnings of the road conditions.

  • Analyzed in the NFDS, The average number of fires in vinyl temporary buildings is more than 1,000 in annually. And the number of deaths and injuries was around 30 people in every year. According to the National Fire Agency, There are 142,386 vinyl temporary buildings for Agriculture and Fishery, of which 4,720 are residential vinyl temporary buildings in illegally. Model house is subject to regulation in fire-related law. But, even though it's the same temporary building, Vinyl temporary building is not subject to regulation. For this reason, Vinyl temporary buildings are left in the blind spot of fire safety. Therefore, In this study, We propose that amend of Act on installation and management of firefighting systems, make of temporary fire safety controller, develop and apply of alarm system that is connected to a single-alarm smoke dretector, organize and operate volunteer fire brigade of the crop group to prevent and extinguish the fire.

  • Purpose: Compared to cities, rural areas are in a medical blind spot and face difficulties in accessing medical services due to inconvenient transportation facilities, lack of medical facilities, and the heavy burden of medical expenses. This study was carried out to identify the problems relating to the musculoskeletal system of the elderly in rural and fishing villages, which are medically vulnerable areas, and sought to present a regionally differentiated healthcare model. Methods: The study was conducted in 80 elderly people in two rural villages and two fishing villages after seeking inputs regarding medically vulnerable groups in the Gyeongnam Province. Postural balance and muscle flexibility were assessed and postural evaluation was conducted to identify musculoskeletal problems and gait stability. Strength and range of motion for each body segment were assessed for evaluating functional motion. Results: The elderly in both rural areas showed forward head posture characteristics. The strength level of the elderly in both rural areas was higher than the average, but their flexibility and balance ability were lower than the average. Conclusion: The musculoskeletal problems of the elderly in rural and fishing villages in this study did not show regional characteristics according to the area of residence. However, overall flexibility and balance ability appeared to be reduced. Therefore, a new management model connecting the region and the university is necessary in preparation for the coming era of community care.

  • Purpose: The number of patients suffering from depression is rapidly increasing worldwide, and by 2030, it is expected to pose a severe social and economic burden. Reports suggest that approximately 30% of subjects with symptoms of depression do not attempt treatment. Therefore, predicting the characteristics of subjects with depressive symptoms who have not even attempted counseling treatment is essential to increase the participation rate for such treatment. This study intends to predict the participation rates for psychological counseling treatment for depression among subjects with depressive symptoms. Methods: This study used data from the 2021 Korea Community Health Survey (KCHS). Data analysis was carried out using a decision tree to design a model that predicted participation in psychological counseling for depression. Results: The results showed that subjects aged 65 to 74 had difficulty understanding the explanations of medical staff even though they did not have cognitive impairment. Only 11.1% of this group received psychological counseling, which was the lowest rate among the various age groups. Among the subjects, 62.4% of those aged 19-44 or 45-64, who had suicidal thoughts and attempted suicide, received psychological counseling and this was the highest rate among the age groups surveyed. Conclusion: The identification of people showing depressive symptoms is crucial for encouraging them to undertake treatment. Also, proper depression-oriented medical services should be developed and implemented for people with depressive symptoms who exhibit a blind spot towards attempting treatment.
