This Paper introduced a proper time evaluation for railway emergency response staffs using the Therblig Analysis. We defines what Activities the emergency response staffs should take when the fire occurs on the railway. This has been possible through the development of the scenario that is focused on the fire accident and it also has been driven to minimize the spread and damage of the accident. Gilbreth's Therblig Analysis has been used here to derive the reasonable time that would take for the emergency response staffs to respond to the fire accident on the railway system. We developed Emergency Response Scenario against Accidents and defined the Activity of the main Action for Emergency Response staffs.

Reinforced concrete column is an effective structural element to take advantage of high strength concrete. This paper presents an experimental and analytical strength of high strength concrete rectangular tied column sections under eccentric loading. The test variables are concrete strength, steel ratios, slenderness and eccentricity. The analytical results of the ACI's rectangular stress block, Zia's modified rectangular stress block, and a trapezoid block are compared with experimentally obtained data. It may be concluded that the trapezoid stress block provided the most reasonable column section capacities for high strength concrete columns.

The purpose of this paper is to setup reasonable criterion for underwriters to reimburse the expenses of suing and labouring incurred by assured, using game theory. As for the upper limit for the reimbursement, MIA and ICC do not mention at all but stipulate that proper and reasonable expenses shall be reimbursed, while ITC-Hulls set the amount insured as the upper limit to compensate the sum of expenses and damage loss. And as for failed measures of averting and minimizing loss, MIA and ICC do not mention either, while ITC-Hulls stipulates underwriters shall compensate the expenses and damage loss within the amount insured. The main results of this paper are as follows: First, it is for the benefit of underwriters to reimburse the expenses incurred to take such reasonable measures to avert or minimizing a loss which would be recoverable under the insurance. Second, the expenses of single measure should not be above the amount insured. Third, even if the measures failed, the expense should be reimbursed if it is less than the expected value of the subject-matter insured that could be recovered by the measures. Last, if the measures are taken several times individually, even if the sum of expenses might be above the amount insured, it should be reimbursed.

Objectives : This study aims to systematically examine the determinants of the intention to take herbal medicine among individuals with experience in Korean medicine. Methods : This study utilized the 3,245 respondents from the 2020 Korean Medicine Utilization and Herbal Medicine Consumption Survey who reported having used Korean medical services; the responses were selected through a complex sample analysis, and analytics techniques including frequency analysis, Rao-scott chisquare test, and logistic regression were used to analyze the responses. Results : The results of data analysis reveal that the intention to take herbal medicine in the future among these individuals was significantly influenced by factors such as enrollment in private health insurance, the facility environment of Korean medical institutions, and treatment outcomes. Conclusions : Therefore, it is imperative for Korean medical institutions to continuously try reasonable action strategies, including improving medical facilities/environments and building institutional mechanisms among medical staff and members to enhance the quality of Korean medical services. Additionally, the Ministry of Health and Welfare needs to make policy efforts to reduce patients' medical expenses, such as reducing the co-insurance rate in the pilot project of applying health insurance to herbal medicine.

This study was conducted to investigate the nutrient supplement use and its related influencing factors by high school students in Chonbuk area. Self administered questionnaires were collected from 489 (urban: 268, rural: 221). Statistical data analysis was completed using a SPSS v. 10.0 program. The results are summarized as follows. According to the general characteristic of subjects, the job and education level of parents and family monthly income respectively affected the nutrient supplement use of subjects (p<0.001). According to the living area, taking a nutrient supplement of parents and nutritional information respectively affected the nutrient supplement use of subjects (p<0.001). About 42.2% of subjects, who taking a nutrient supplement, responded to take a traditional medicine type, and 24.4% of them a multivitamin. Their mothers were important recommended person. The main reason for taking was 'to recommended from parent' (38.5%) and 'recovery from tiredness' (29.6%). The main reason for not-taking was that they were health, therefore nutrient supplements were not necessary. In the future about 43.7% of urban and 33.9% of rural area responded to take a nutrient supplements (p<0.05). These findings show that the behaviors of nutritional supplement usage by subjects are not reasonable, and their supplement usage tends to be affected by general characteristics. Therefore, nutritional understanding and education that are intended to from reasonable behaviors toward nutritional supplement usage of adolescents should be provided with considering the relationship between general characteristic of subjects and supplement usage.

입지는 모든 산업에 있어서 성공의 핵심적인 결정요소이기 때문에 잘못 선정된 입지는 아무리 유능한 운영자라 할지라도 많은 어려움을 겪기 마련이다. 이에 본 연구는 보다 합리적이고 간편한 소매점의 입지 선정 모델을 만들고자 서울시 소재 대형마트를 대상으로 허프의 확률이론을 적용하여 점포별 점유인구를 산출하였다. 점유인구를 바탕으로 모든 단위 구역을 상점간 경쟁 상대를 나타내는 4개의 시장유형, 즉 독점시장, 과점시장, 경쟁시장 비경쟁시장으로 구분하였다. 신규점포가 입지에 가장 합리적인 장소는 점유인구를 가장 많이 확보할 수 있는 지점으로, 비경쟁시장을 최대한 확보할 수 있으면서, 경쟁시장에서 멀리 떨어진 곳이다.

As a construction project is recently becoming large-scaled and complex, construction process plan and management for successful performance of a construction project has become more important. Especially a reasonable estimation plan of activity duration is required because the activity duration is directly related to the determination of the entire project duration and budget. However, the activity duration is used to estimate by the experience of a construction manager and past construction records. Furthermore, the prediction of activity duration is more difficult because there is some uncertainty caused by various influencing factors in a construction project. This study suggests an estimation model of construction activity duration using neural network theory for a more systematic and objective estimation of each activity duration. Because suggested model estimates the activity duration by a reasonable schedule plan, it is expected to reduce the error between planning duration and actual duration in a construction project. And it can be a more systematic estimation method of activity duration comparing to the estimation method by experience of project manager.

The current methods, such as Binomial Probability Distribution or T-test, to calculate the number of samples of Precise Guided Missiles(PGMs) for test and evaluation are statistically problematic to make reasonable decisions thus use the budget efficiently. Also, the method to verify an accuracy rate of the PGMs using these old methods seems to be lack of objectiveness. This paper presents an effective, efficient solution adapted from the clinical medicine testing method of healthcare industry research, which may overcome our problems. This method considers and addresses both manufacturers' and consumers' risk simultaneously. By taking into account the weapon system project characteristics which take a relatively longer time and require higher-level budget, this approach also suggests a reasonable and feasible method to determine the amount of samples of the PGMs and making a criterion to verify an accuracy rate of the missiles that are required to test. Thus, this method is expected to contribute to acquisition and operations of high-reliability PGMs by MND and its field-users.

Building information modeling (BIM) technology based on 3D modeling has been applied to the entire domestic construction industry since 2010. It can calculate quantity take-off considering construction productivity at design phase. Based on this, it is possible to improve the reliability of construction cost prediction of design phase in the process of cost estimation. However, Building Information Level (BIL) defined by Ministry of Land, Infrastructure and Transport and Public Procurement Service does not seem to offer doable environment due to the lack of detailed application items. By calculating construction cost that meets Construction Cost Estimate Accuracy by American Association of Cost Engineers (AACE) through quantity take-off and cost estimation based on 3D modeling of BIM technology, a BIL improvement proposal at design phase for Mechanical Contracts and Construction is provided here. Results showed that properties including outline and minimum specification of the main equipment, internal main piping, and internal main duct should be defined from the intermediate design phase to have reliable cost estimation.
