The purpose of this study is to identify ways of remodeling from the traditional hanok to the modern local governmental facility in 1910s. Analysing architectural drawings in the National Archives of Korea, 58 hanok remodeling cases of 52 facilities were verified like the provincial office, county office, county court from 1907 to 1910s. Using hanok as the local governmental building, exterior walls were all changed to the scaled-wooden wall like one of western-wooden building in 1910s and the western-style entrance was set. Change of the plan caused by remodeling interior walls had an intention of the centralized closed plan. Remodeled semi-outer corridor using the space of the eave became changed to the inner corridor with expansion of space. Expansion of hanok for spatial demand was in three ways. First was the expansion towards the eave space, second was direct extension from hanok, and last was the use of external corridor to the new building. Using the eave space was simple but had limitation of space, it was planed with other expansion ways. The way of direct extension was usually used than the one with the corridor, because it was more economical way.

본 연구에서는 T자형의 복도 연결 공간에서 비상 방송음이 명료하고 고르게 전달되는지를 건축음향 시뮬레이션을 이용하여 알아보았다. 복도 공간의 흡음성능 변화, 비상 방송용 확성기의 설치 위치와 간격을 변화시켜 보았으며 변화에 따른 음압 레벨 분포, 음성 전달 지수(STI, RASTI) 분포를 비교하였다. 시뮬레이션 결과 명료한 음성 전달을 위해서는 비상 방송용 확성기를 T자형 복도 연결부의 중심에서 약 10 m를 이격시켜 설치하는 것이 좋은 것으로 나타났다. NFSC의 25 m 설치 간격을 좁히는 경우 더욱 명료하고 충분한 음량을 갖는 비상 방송음이 고르게 전달될 수 있는 것으로 나타났다.

Recently as the rapid increasing of the elderly, silver housing has grown up. Though much fire evacuation and safety law, fire accident is most dangerous problem in our society. So this study is the purpose to analyze evacuation safety in urban silver housing of floor planning by corridor types using human behavior simulation. The methodology of this study is 'Literature Review' and 'Simulation'. This study has been carried out on silver housing's definition, types, fire safety theory and relation law. To proof evacuation safety, this study measured escaping time, longest distance, and bottleneck counting using human behavior simulation. This study use game engine simulation program to analyze 6 corridor types experimental model. As the result of simulation, this study compare between ASET and simulation result. The result come down to 3 part. First, double loaded corridor type is the most dangerous on urban silver housing. Second, Safe shelter's location and number cause increasing of escaping time. Lastly escaping time is influenced by behavior of agent, bottle neck strike frequency.

In the case of medical facilities, the evacuation time is delayed due to the decrease in the number of people in the hallway and exits due to the increase in the width of evacuation by using mobile beds, wheelchairs, crutches, etc. Accordingly, it is considered to secure evacuation capacity to reduce evacuation time according to corridor width and exit width. Accordingly, we would like to compare the standards related to the evacuation capacity of medical facilities in Korea and NFPA, derive differences, and use evacuation simulations to compare evacuation times according to changes in corridor width and exit width. In Korea, it is calculated based on the floor area by use, but in the case of NFPA 101, the number of evacuation routes, stair width, corridor exit width, and two-way door width was stipulated depending on the number of people. Using evacuation simulation, efficient evacuation capacity is calculated according to the reduction of evacuation time by changing the width of the hallway, changing the width of the exit, the width of the corridor, and the width of the exit. The evacuation simulation is intended to be used to secure evacuation safety of domestic medical facilities by calculating the effective evacuation time reduction by changing the width of the hallway and exit.

Purpose: The purpose of this study is analyze linkage and spatial and structural characteristics of outpatient department and diagnosis/treatment area of geriatric hospitals based on quantitative analysis, according to function and corridor types. Methods: To examine structural characteristics and correlation of outpatient department and diagnosis/treatment area of six geriatric hospitals according to the corridor type, were systemized according to the function and corridor type and made into a j-graph, and an index was created by using space syntax to understand spatial characteristics. Results: 1) Different functional spaces are connected by a corridor, which, therefore, can be an axis of the connectivity and linkage of functional spaces and an important element in a clear hierarchy. 2) Treatment areas were disconnected from different functional spaces and, therefore, the accessibility was low. Many hospitals had an arrangement plan for treatment and diagnosis areas, and recent hospitals have segmented treatment areas within the rehabilitation space, which resulted in deeper space. 3) In terms of the level of integration, more integrated reception area meant shallower spatial depth, and deeper space for treatment and diagnosis areas. Implications: Spatial relation of outpatient department of geriatric hospitals was analyzed based on characteristics of the elderly.

Objective: To analyze the long-term changes in maxillary arch widths and buccal corridor ratios in orthodontic patients treated with and without premolar extractions. Methods: The study included 53 patients who were divided into the extraction (n = 28) and nonextraction (n = 25) groups. These patients had complete orthodontic records from the pretreatment (T1), posttreatment (T2), and postretention (T3) periods. Their mean retention and postretention times were 4 years 2 months and 17 years 8 months, respectively. Dental models and smiling photographs from all three periods were digitized to compare the changes in three dental arch width measurements and three buccal corridor ratios over time between the extraction and nonextraction groups. Data were analyzed using analysis of variance tests. Post-hoc multiple comparisons were made using Bonferroni correction. Results: Soft-tissue extension during smiling increased with age in both groups. The maximum dental width to smile width ratio (MDW/SW) also showed a favorable increase with treatment in both groups (p < 0.05), and remained virtually stable at T3 (p > 0.05). According to the MDW/SW ratio, the mean difference in the buccal corridor space of the two groups was $2.4{\pm}0.2%$ at T3. Additionally, no significant group ${\times}$ time interaction was found for any of the buccal corridor ratios studied. Conclusions: Premolar extractions did not negatively affect transverse maxillary arch widths and buccal corridor ratios. The long-term outcome of orthodontic treatment was comparable between the study groups.

Purpose: The purpose of this paper is to develop a predictive model for patient visibility in Korean ICUs (corridor or continental type). Methods: The measures of static visibility were used to quantify the patient visibility (upper third part of the patient bed) from the nurse station. The measure of space programme and area distribution (patient zone percentage, staff zone percentage and departmental gross square meter per patient bed) were calculated by using AutoCAD and MS Excel programs. Regression analysis was conducted for visibility as dependant variable with independent variables of patient area percentage, staff area percentage as well as departmental gross square meter per bed by using IBM SPSS. Results: (1) Average patient visibility and percentage of patient area in ICU shows a strong negative correlation ($r^2$=0.66), p=0.01. (2) Patient visibility in Korean ICU (corridor or continental type) can be calculated as below with the given conditions: Y= $-1.449(X)+124.3{\pm}6$, Y is the total visibility of the ICU (corridor or continental type) and X is the percentage of patient area in the unit. Conditions:1. Given that the unit has a mixed programme of open bed and closed patient rooms and 2. The unit have a minimum of 20% patient rooms. Implications: This study may contribute to the visibility analysis of existing and future ICU design (corridor or continental type) in Korea to achieve maximum patient visibility and reduced patient mortality.

In order to assess the present status of the fragmentation of ecosystem and the building of ecological corridor, 79 EISs(Environment Impact Statements) which were conducted in Kyunggido and Kangwondo have been reviewed using 36 analysing factor. The results obtained from this study were as follows: a. The most frequently appearing type of ecosystem fragmentation was 'mountain vs. mountain type in topography' and '2 vs. 2 grades in the degree of green naturality.' b. The most frequently listed fauna in EISs included squirrels and wild rabbits for mammals, grass snake and pit viper for reptiles, and tree frog and true tree frog for amphibians. c. Among the EISs for 50 projects, the construction of ecological corridor mentioned in only 4 projects and other structures such as drainage duct and closed conduit in 14 projects were suggested as ecological corridor. There were no corridors suggested in 32 projects. Thus, in case of using other structures for wildlife animals but ecological corridors, it should be accompanied by incidental facilities for including animal movement.
