The safety management of a road network comprises four basic inter-related components:identification of sites(black spot) requiring safety investigation, diagnosis of safety problems, selection of feasible treatments for potential treatment candidates, and prioritization of treatments given limited budgets(Persaud, 2001). Identification process of selecting black spot is very important for efficient investigation of sites. In this study, the accident prediction model for EB method was developed by using accident data and geometric conditions of black spots selected from four-leg signalized intersections in In-cheon City for three years (2004-2006). In addition, by comparing the rank nomination technique using EB method to that by using accident counts, we managed to show the problems which the existing method have and the necessity for developing rational prediction model. As a result, in terms of total number of accidents, both the counts predicted by existing non-linear regression model and that by EB method have high good of fitness, but EB method, considering both the accident counts by sites and total number of accident, has better good of fitness than non-linear poison model. According to the result of the comparison of ranks nominated for treatment between two methods, the rank for treatment of almost sites does not change but SeoHae intersection and a few other intersections have significant changes in their rank. This shows that, with the technique proposed in the study, the RTM problem caused by using real accident counts can be overcome.

The purpose of this study is to find that people's visit to a dementia home exhibition hall is effective at improving their perception of dementia. The satisfaction of visitors to the dementia home exhibition hall and a change in their perception of dementia after the visit were analyzed. The study subjects were 52 residents in S city. This study had been conducted from April, 5 to May, 25, 2018. The dementia home exhibition hall has welfare kits installed in an entrance, a rest room, a living, and a kitchen. Virtual reality experience program and the program of wearing clothes to experience an elderly person were performed together. As a result, the visitors' satisfaction was high overall, and their visit was educationally effective at improving their perception of dementia. After their visit to the hall, the residents showed high increases in the scores of the questions about the perception of dementia causes, dynamism & system, symptoms & diagnosis, and treatment & prevention. The residents with middle years and higher of age were more satisfied than those in other age groups with the introduction of dementia, and prevention methods, introduction of safe and comfortable home environment, and appropriateness of experience program. In this study, it was positive that the differentiated experience program which was not existed actively led the participation of the target person and attracted high education satisfaction in a short time. In the future, it will be necessary to develop an extended experience program, provide an environment for direct experience of dementia, and perform a continuous program to draw more citizens' attention.

We carried out this study to reduce the gaps between medical institutes and between medical personnels and help to improve medical service quality, by classifying diagnoses and related intervention through the development of standard nursing intervention and by computerizing protocols. We considered two processes: one is the development process of home nursing standard intervention, and the other is the process of computerizing its related protocols. For the former, research covered analysis of home health care practices, development of client assessment protocol, of patients diagnosis protocols, and of patients intervention protocol. For the latter, strategies for home health care information systems should be set up and it constituted four research contents of analysis, design, management and evaluation of the systems. We also trained and educated home nurses who work at home health service center, by making them use the manual of home health care information systems at a certain city of P. In this study, therefore, we developed elements of standard home health care mediation so that they could be included in the forms of home health information note, home health progress note, and home health progress summary, home health discharge summary. Because standard home health care intervention has been developed, it became easier to exchange information between different home heath service center offices, can prevent from missing or redundant information, and contribute to standardization of hospital terminologies when EMR and HMR are developed.

This study aimed to identify appropriateness and efficiency in the DRG payment system by analysing the hospital length of stay and changes in fees before and after the application of DRG payment system. The subjects of the study were a total of 398 patients consisting of 204 for the fee for service system and 194 for the DRG payment system. They received surgery in the Obstetrics and Gynecology (OBGY) department of a general hospital in G metropolitan city between January and December 2013. The mean hospital length of stay was significantly decreased after application of the DRG payment system(p=0.013). Total fees, insurance charges, and deductions increased significantly(p<0.001), and non-payment charges and total deductions decreased significantly(p<0.001). Application of the DRG payment system reduced length of stay, non-payment charges and total patient's cost sharing and increased out-of-pocket, insurance charges, and total fees.

This study was conducted to compare the rates of hyperlipidemia, hypertension, high blood glucose, and liver dysfunction, between 64 obese children (24 boys and 11 girls who were moderately obese, and 21 boys and 8 girls who were severely obese) and 45 normal weight children (31 boys and 14 girls) from 13 elementary schools in Kangnung city. Among the boys with severe obesity, the levels of serum triglycerides and LDL-cholesterol (133.60 $\pm$ 49.99 mg/dl and 105.00 $\pm$ 41.12 mg/dl( respectively) were significantly higher compared to the normal Weight group (81.16 $\pm$ 23.59 mg/dl and 87.74 $\pm$ 32.095 mg/dl, respectively) of moderately obese group (102.30 $\pm$ 36.03 mg/dl, 89.99 $\pm$ 32.10 mg/이, respectively). In girls, only serum triglycerides were significantly higher in the severely obese group (154.30 $\pm$ 46.84 mg/dl), compared with the normal weight group (80.00 $\pm$ 25.31 mg/dl) or moderately obese group (106.40 $\pm$ 41.73 mg/dl). In boys, blood pressure in the severely obese group (systolic: 120.5 $\pm$ 9.74 mmHg; diastolic: 80.95 $\pm$ 10.44 mmHg) was significantly higher compared with the groups of normal weight or moderately obese children. The rate of hypertriglyceridemia was significantly different among normal weight, moderately obese, and severely obese boys (9.7%, 41.7%, and 76.2%, respectively). The proportion of boys who had an Atherogenic Index(AI) higher than 3 was found to be significantly higher in the severely obese group (28.6%), compared to 6.5% in the normal weight group and 4.1% in the moderately obese group. Among boys, a significantly higher rate of hypertension was found in the severely obese group, which showed high systolic blood pressure and high diastolic pressure (81.0% and 81.0%), compared with the normal weight group (16.1% and 22.6%) and moderately obese group (33.3% and 33.3%). In conclusion, the diagnosis and management of obese children needs to be tailored to gender and the degree of obesity. Furthermore, a systematic management program needs to be developed for early screening and detection of obesity in order to minimize the risk of hyperlipidemia and hypertension, especially in severely obese children.
Twin stone pagodas of the ruins of Kamunsa temple at Kyongju city, Kyungsangbukdo
were believed to be built in 682 during the Unified Shilla Kingdom. The 13.4-m-high granodiolite pagodas with the base of 6.78 m x 4.4 m are the largest three-story stone pagoda in Korea. The western pagoda which was re-organized in 1959 is observed to be on the process of severe weathering. Also, some stone contacts are represented by the shape of sharp chevron, which is probably caused by the uneven loading due to the structural unbalance. For the structure-safety diagnosis of the western pagoda, it is necessary to understand its site characteristics and surrounding subsurface environment. Combined geophysical survey such as seismic and resistivity methods was carried out around the western pagoda. The range of 55∼350 Ωm is shown around the pagoda from the electrical resistivity mapping by the Wenner method. The higher resistivities occur the southwestern area, while the lower (<100 Ωm) values indicating the weaker subsurface appear to be on the northeastern area. This result coincides with the measurement of a leaning angle of the pagoda. Along 6 seismic lines, about 3-m-thick uppermost section around the pagoda shows the P-wave velocity of 200∼700 m/s from the refraction survey. Based on the integrated geophysical survey, the foundation
of the pagoda is estimated to be in the form of 11-m-side square down to the depth of 3 m.

Objectives: This study aimed to assess the status of Scrub typhus, Leptospirosis and HFRS(hemorrhagic fever with renal syndrome) among farmers with febrile illness. Methods: We involved a total of 841 farmers who had febrile illness(508 and 333 village residents were, respectively, three and four district of Gyeongju city) selected during autumn of 2014 and 2015. Data were collected by survey questionnaires and blood sample examination. Results: Serum response rate for Scrub typhus and Leptospirosis was 1.5% each and 1.9% for HFRS. Serum response rate for Scrub typhus was significantly higher for tick-bite cases(38.5%), while Leptospirosis was significantly higher for those who were in fruit-planting work(23.1%). Similarly, serum response rate was significantly higher for HFRS who were working in venyl green house work(25.0%). Conclusions: Government authority should develop effective and efficient preventive strategies to create awareness of infectious diseases among farmers. Extending information, education and communication be reached to farmers that could change their perception and help early diagnosis and treatment and reduce the disease burden and its complication.
Purpose: In general, traffic accidents occur sporadically, so there are various limitations in terms of time and cost when conducting field investigations to prepare prevention and prevention measures. In particular, with the transition to a non-face-to-face society after the COVID-19, there is a greater need to prepare a replacement for field surveys. Therefore, in this study, Roadview provided by various websites was used as an alternative to field surveys in Sasang-gu, Busan City. The possibility was evaluated. Method: The research method was to extract vulnerable points for traffic accidents that occurred between 2016 and 22 and analyze road views based on the field survey evaluation items provided in the Traffic Safety Diagnosis Guidelines. Result: The main result was that Sasang-gu was most vulnerable to accidents involving elderly pedestrians at Sasang-ro, Daedong-ro, and Hakjang-ro. As a result of a detailed analysis of vulnerable points through Road View, Sasang-ro needed control of commercial vehicles and protection of the transportation vulnerable in the market commercial area. Daedong-ro was vulnerable to illegal on-street parking and slope merging sections, and Hakjang-ro was vulnerable to roads that were prone to speeding. When evaluating the possibility of replacing Roadview's field survey based on the results of this analysis, Roadview was able to effectively evaluate most items, such as separation of sidewalks and the location and spacing of safety facilities. However, there were limitations in items such as actual measurement performance. Conclusion: In other words, the road view can replace most field surveys, and the actual measurement evaluation items can be judged to be useful as auxiliary data, resulting in time and cost savings and high efficiency.
