Since the number of social enterprises have been increased more than double over the past five years, the determinant of their growth by regional comparison is examined in this paper. In terms of the sale determinant, experimental results show that the total number of workers, business history, and capital intensity in Seoul metropolitan area, the total number of workers, business history, and capital intensity in Gyeongsang area, the total number workers, business history, and the dependence on government subsidies in Chungcheong area, the total number of workers, and the capital intensity in Jeolla/Jeju area have showed positive effects. In terms of asset determinants, experimental results show that the total number of workers, business history, and capital in Seoul metropolitan area, the capital in Gangwon area, the total number of workers, business history, and capital in Gyeongsang area, the total number of workers, business history, and capital intensity in Chungcheong area, the total number of workers, capital, and capital intensity in Jeolla/Jeju area have showed positive effect.

Some studies were conducted for the purpose of minimizing total clearance time for rapid evacuation from the indoor spaces when disaster occurs. Most studies took a long time to calculate the optimal evacuation route that derived minimum evacuation time. For this reason, this study proposes an evacuation route assignment algorithm that can shorten the total clearance time in a short operational time. When lots of exits are in the building, this algorithm can shorten the total clearance time by assigning the appropriate pedestrian traffic volume to each exit and balances each exit-load. The graph theory and greedy algorithm were utilized to assign pedestrian traffic volume to each exit in this study. To verify this algorithm, study used a cellular automata-based evacuation simulator and experimented various occupants distribution in a building structure. As a result, the total clearance time is reduced by using this algorithm, compared to the case of evacuating occupants to the exit within shortest distance. And it was confirmed that the operation takes a short time In a large building structure.

The study analyzes the appropriate number of people per a household by applying an evacuation simulation to a 27-floor apartment in accordance with the NFPA 101 standard. The results of the analysis are as follows. First, if there are three people residing in each household, there would be 156 households in total, of which 85.25% were evacuated within 5 minutes. Second, 208 households with 4 residents were evacuated within 5 minutes. Third, if there are five people residing in each household, there would be a total of 260 households and 71.92% of residents were evacuated within 5 minutes. Lastly, 62.82% of the 312 households, each consisting of 6 people, were evacuated within 5 minutes. Measures to reduce evacuation time include determining the width of the stairs according to the number of people indoors, the number of floors in the building, the slope of stairs, and the users' characteristics, the design reflecting the ventilation conditions of the stairs, the installment of outdoor evacuation stairs, two-way stairs, evacuation lift, and the installation of an evacuation safety zone for people to evacuate outside of the building in the middle floors. In addition, measures, such as the mandatory installation of automatic emergency door open-close device to the rooftop, are required to facilitate rooftop evacuation.

The study aims at analyzing an underground station refuge model using EXODUS, one of the refuge simulation programs. The model for simulation is the Daegu Subway (Joongang-ro station). The details of the accident are referred to as the simulation condition the refuge time of traveling from the $3^{rd}$ basement platform to the $1^{st}$ basement is mainly calculated, with passengers numbering 1,000 including 329 at car 1079, 320 at car 1080, and 360 who are not on board. Reference data is used to set up the position of passengers. CFAST fire simulator is also used, and a fast curve among the $t^2$ growth curves, selected as fire growth scenario. The zone is divided into a total of 24 including 18 at the $3^{rd}$ basement platform and 6 at the $2^{nd}$ basement the $1^{st}$ basement is excluded in the fire simulation, however.

This research grasped the difference of between the daily medical expenses and the medical expenses reduction rate also the cause of change. In the centre, it was conducted in order to offer the necessary basic data to a recuperation pay management solution's establishment. This research surveyed across the country's urban region 50-general hospital's the infective enteritis disease for a year. Then it was conducted the average daily medical expenses and the average medical expenses reduction rate as a distinguishable survey that is a hospitalization and an outpatient the result is followed. The inpatient daily medical expenses correlated with the total number of medical institution personnel, and the outpatient daily medical expenses correlated with the number of beds.. Inpatient medical expense reduction rate was correlated with number of beds and the total number of medical institution personnel. The interaction between medical institution information and daily medical expenses was found to have a positive (+) effect on the total number of medical institution personnel, as well as the numbers of inpatients vs. outpatient. This research about the medical expense reduction rate and daily medical expense help medical institution's efficient, rational decision making and it will be an important basis of a priority recuperation pay's policy.

Existing pedestrian and evacuation models generally seek to find locally optimal solutions for the shortest or the least time paths to exits from individual locations considering pedestrian's characteristics (eg. speed, direction, sex, age, weight and size). These models are not designed to produce globally optimal solutions that reduce the total evacuation time of the entire pedestrians in a building when all of them evacuate at the same time. In this study, we suggest a globally optimal model for indoor pedestrian evacuation to minimize the total evacuation time of occupants in a building considering different distributions of them. We used the genetic algorithm, one of meta-heuristic techniques because minimizing the total evacuation time can not be easily solved by polynomial expressions. We found near-optimal evacuation path and time by expressing varying pedestrians distributions using chromosomes and repeatedly filtering solutions. In order to express and experiment our suggested algorithm, we used CA(cellular automata)-based simulator and applied to different indoor distributions and presented the results.
