This study aimed to extract the priority safety improvement factors for coastal passenger ships and analyze the perception gap between groups. To extract the improvement factors, we formed an expert group with maritime safety supervisors, passenger-ship safety inspectors (PSIs), and captains of passenger ships, and then conducted a Delphi survey. We found, using a hierarchy process, that the improvement factors were divided into three factors in Level 1 and ten factors in Level 2. For the relative importance analysis using the AHP (Analytic Hierarchy Process) model, we also formed two groups: an inspector group with maritime safety supervisors and PSIs, and an examinee group with safety managers, captains, and crews. Consequently, the factors of designation of public transportation for passenger ships and supporting the welfare of the crew were evaluated as the most important among the extracted factors. We conducted a t-test for the analysis of the perception gap between the two groups. Three perception gaps were found: increasing the inspection personnel, strengthening the qualification of the inspection personnel, and expanding the safety operation center. The result of this study will be useful for improving the safety policy of coastal passenger ships.

Purpose: With the increasing national interest in health, the number of health examination centers is growing rapidly, and it is growing as independent medical institutes separated from hospitals. With the growing functions and size of health examination institutes, considerations for testees, who are the most important users of the health examination centers, have taken the back seat. In particular, for health examination programs that take on a sequential traffic line, it is important to be aware of the space of each examination room, but the lack of a scientific evaluation method for this has resulted in great discomforts for testees using the health examination center. Method: Thus, this study proposes risk evaluation indices (RCF TCF, RC3, RR, ARR), and set a standard health examination program based on the national health examination program. This was applied to 11 different sized health examination centers to find their features, and together with identifying the trends of the indices, the following results were deduced. Result: 1) ARR showed a wide-range feature as the number of unit spaces increased, while RR were discovered regardless of the size, thus displaying local features. 2) The increase of ARR is affected more by internal factors in the health examination center than from outside factors. 3) By gender, when separating the basic health examination fields, the connective relation of the comprehensive health examination fields had a big effect on ARR. 4) By becoming larger, the fields of function become independent and the waiting space that results from it increases the number of total movement, so there is space for improvement in this.

This study aimed to analyze the characteristics of health check-up recipients in their 20s and 30s in Korea and identify factors influencing the participation rate in order to enhance the rate of health check-ups. The study population and methods utilized data from the 8th year of the Korea National Health and Nutrition Examination Survey, specifically the 2nd year (2020), and targeted 1,453 Korean residents aged between 20 and 30. The factors affecting health check-up participation were divided into sociodemographic factors, health behavior factors, mental health factors, and medical utilization factors, and both simple logistic regression analysis and multiple logistic regression analysis were conducted. The analysis results showed that educational level, marital status, type of health insurance, employment status, and subjective level of health were the factors influencing health check-up participation among Korean individuals in their 20s and 30s. These research findings can serve as foundational data for improving the health check-up participation rate among individuals in their 20s and 30s.

The purpose of this study is to find a way to increase the examination rate by presenting the current state of national health examination. To this end, demographic factors(Gender, age, income level, education level) and health factors(Smoking, alcohol, obesity, subjective health status) were selected, and whether the selected factors were different for each group, and the examinees according to the number of hospitals and income level were visualized. As a result, except for subjective health status in health factors, population factors, and number of hospitals were all related to the examination. In addition, among the age factors of the demographic factor, those in their twenties and those with a low income level and those who were underweight among the health factors of obesity had a high rate of non-testing. Therefore, it is considered necessary to promote, support, and educate those untested by these groups.

Recently, health examination centers have been changing from auxiliary medical facilities to key and independent medical facilities. However, it is not easy to improve medical facilities, including health examination centers, due to the variable characteristics of the relationship between humans and space. Therefore, this study was done to develop a pedestrian-based discrete event simulation analysis program to examine the problems and develop methods for improvement. The program was developed to analyze five evaluation indices and the density of examinees. The problems were derived by analyzing the required time, capacity, and queue size for each examination through simulations. We reduced the examination time and moving distance, increased the capacity, and distributed the queues by adjusting the medical services and relocating the examination rooms. The results were then quantitatively verified by simulations.

Kidney stones are a common disease with an annual prevalence of about 30,000 people in Korea, and are deeply related to an increase in chronic kidney disease, high blood pressure, coronary artery disease, metabolic syndrome, type 2 diabetes, hyperlipidemia, and abdominal obesity. Therefore, in this study, 135 examinees who visited a general hospital in Dalseong-gun from May 2019 to June 2020 for a medical examination were examined. The relationship between kidney stones and factors related to obesity and metabolic syndrome were found in abdominal ultrasound. I tried to find out the relevance. As a result of the study, the risk of kidney stones in the abnormal group was increased by 4.255 times compared to the normal group in total cholesterol factor, and the risk of kidney stones in the abnormal group was increased by 2.072 times compared to the normal group in the low-density lipoprotein cholesterol factor. Total cholesterol factor and low-density lipoprotein cholesterol It was found that the factor affects the prevalence of kidney stones and metabolic syndrome. Since the risk of kidney stones is related to total cholesterol and low-density lipoprotein cholesterol factors, active attention should be paid to preventive purposes through health check-ups.
