Background: As the government has recently been discussing the expansion of the disaster health expenses support project, we would like to confirm the characteristics of beneficiaries of the support project, particularly those of high-cost beneficiaries. Methods: Using the database of catastrophic health expenditure support project from 2019-2020, this study aims to confirm the characteristics of high-cost beneficiaries focusing on the overlap of the relieved out-of-pocket systems, known as the out-of-pocket ceiling system and the system for rare incurable diseases. Logistic regression analysis is used to examine this issue. Results: In order to analyze the factors influencing high-cost beneficiaries, five models were created and analyzed, including the status of duplicated beneficiaries for relieved out-of-pocket systems, sociodemographic and economic factors, and individual health status as sequential independent variables. All five models were statistically significant, of which economic factors had the greatest impact on the model's predictions. The main results indicated that those who benefited from multiple systems in duplicate were more likely to be high-cost beneficiaries, and there is a higher probability of incurring high health expenses among the underage. In addition, within the beneficiaries of catastrophic health expenditure support project, it was observed that higher health insurance premium percentiles are associated with a higher proportion of high-cost beneficiaries. Conclusion: This study examined the characteristics of high-cost beneficiaries by encompassing reimbursement and non-reimbursement. According to this study, it is expected to be used as basic data for setting priorities and improving the current criteria of catastrophic health expenditure support project, aiming to sequentially expand the program.

This paper attempts to provide a theoretical basis for the design of high-strength concrete columns in terms of the spacing of lateral reinforcement. In order to achieve this, important concepts had to be addressed such as the choice of a measure of ductile behaviour and a realistic high-strength concrete stress-strain model, as well as limiting factors such as longitudinal steel buckling and lateral steel fracture. A design method incorporating above factors are suggested in the paper. It is shown that both buckling of longitudinal steel and hoop fracture will not demand a reduction in spacing of lateral ties with increase in compressive strength of concrete.

The purposes of this study were to find out the catalogue and online-order apparel shoppers' impulsive purchase orientation and impulsive purchase stimuli. Self-administered questionnaires were distributed to women over than 20 years, and collected from middle to the end of November in 2000. Frequencies, percentages, and mean were calculated. One-way ANOVA, chi-square test, factor analysis, and cluster analysis were used, and Duncan's Multiple Range test was followed. 1. Factors of impulsive purchase orientation were relax from negative moods, design property, inducement from neighbors, taste congruence, price property of apparel, positive moods, and loose-control, and were segmented into the low impulsive purchaser, the reasonable purchaser, the fulfilled with positive moods, and the high impulsive purchaser. The factors of impulsive purchase stimuli were apparel property, consumer service, sales promotion on the point of sales, and low price. 2. The low impulsive Purchaser was affected little by impulsive purchase stimuli, spent a little money on apparel, and the married with high education level were the most. The reasonable purchaser was affected by sales promotion on the point of sales or low price, spent a little money on apparel, and students or house-wives were the most The fulfilled with positive moods was affected by low price, and students or career women with high education level were the most, but spent less money on apparel. The high impulsive purchaser was affected by various impulsive purchase stimuli, the young unmarried with high education level were the most, and spent more money on apparel. 3. The younger, the unmarried, students or career women, and shoppers with higher income or apparel expenditure showed a higher impulsive purchase tendency for relax from negative mood, design property, for inducement from neighbor, taste congruence, and positive moods. 4. The older, the married, house wives, and shoppers with higher apparel expenditure were stimulated by apparel property or consumer services.

Purpose: This study was conducted in order to identify factors that predict suicidal ideation and depression according to gender among Korean adults. Method: From the data base of the fifth Korean National Health and Nutritional Examination Survey(KNHANESV-1, 2010), data on 4,894 adults aged 19~64 were used. Data were analyzed by application of the Rao-Scott Chi-Square test and logistic analysis with SAS 9.2. Results: Overall, 8.5% of men and 18.1% of women had suicidal ideation during the last year; 7.5% of men and 17.0% of women had depression during the last two weeks. Risk factors for suicidal ideation include perceived high stress(OR male 3.649, female 2.941), depression(OR male 10.109, female 6.033), poor cognition of health status(OR male 8.115, female 6.664), low economic status(OR male 1.898), and low educational status(OR female 1.631). Risk factors for depression include perceived high stress(OR male 2.678, female 3.686), suicidal ideation(OR male 9.925, female 6.022), non-employed(OR female 1.525), married(OR female 2.392), and physical discomfort(OR female 1.545). Conclusions: Based on the above mentioned results, risk factors of suicidal ideation and depression differed according to gender. Development of various policies and appropriate intervention programs according to gender, that lessen the risk of suicidal ideation and depression for adults is needed.

Landslides are one of the natural disasters that cause a lot of financial and human losses every year It will be all over the world. China, especially. The Mainland China can be divided into 12 zones, including 4 high susceptibility zones, 7 medium susceptibility zones and 1 low susceptibility zone, according to landslide proneness. Climate and physiography are always at risk of landslides. The purpose of this research is to prepare a landslide hazard map using the Hierarchical Analysis Process method. In the GIS environment, it is in a part of China watershed. In order to prepare a landslide hazard map, first with Field studies, a distribution map of landslides in the area and then a map of factors affecting landslides were prepared. In the next stage, the factors are prioritized using expert opinion and hierarchical analysis process and nine factors including height, slope, slope direction, geological units, land use, distance from Waterway, distance from the road, distance from the fault and rainfall map were selected as effective factors. Then Landslide risk zoning in the region was done using the hierarchical analysis process model. The results showed that the three factors of geological units, distance from the road and slope are the most important have had an effect on the occurrence of landslides in the region, while the two factors of fault and rainfall have the least effect The landslide occurred in the region.

According to the statistical surveys and studies, insufficient maintenance in the use of existing buildings caused fire and collapse accidents. In this respect, I analyzed the data managed by the current building maintenance and inspection system to find out the actual state of safety management and proposed two significant results. First, regarding the state of the buildings, the safety management status of the small-sized ones, where 20 years or more passed after construction, is the worst and a priority improvement plan is required. Second, there are eight deeply concerning factors for the fire incidents and collapse accidents of buildings. In the order of high risk, these factors are structural strength (seismic design), exterior wall finishing material, basement floor, interior finishing materials, other evacuation facilities, corridors stairs entrances, rooftop, fire partition. We need to have more special designs and management plans regarding high-risk factors as a system to prevent accidents in the building.

High speed milling process is emerging as an important fabrication process benefits include the ability to fabricate micro and meso-scale parts out of a greater range of materials and with more varied geometry. It also enables the creation of micro and meso-scale molds for injection molding. Factors affecting surface roughness have not been studied in depth for this process. A series of experiments has been conducted in order to begin to characterize the factors affecting surface roughness and determine the range of attainable surface roughness values for the high speed milling process. It has previously been shown that run-out creates a greater problem for the dimensional accuracy of parts created by high speed milling process. And run-out also has a more significant effect on the surface quality of milled parts. The surface roughness traces reveal large peak to valley variations. This run-out is generated by spindle dynamics and tool geometry. In order to investigate the relationship between tool setting errors and surface roughness end tilted mills were used to cut aluminum samples. The results indicate that tool setting errors have significant effects on surface roughness and cutting forces.

This run-out is generated by spindle dynamics and tool geometry. In order to investigate the relationship between tool alignment errors and surface roughness the scallop generating mechanism in the ball-end milling with tool alignement errors has been studied and simulated. The results indicate that tool alignment errors have no significant effects ell the dimension of scallops in for flat planes.
