In residential spaces, sanitary zones are where the most basic needs of human beings are met and are used by all members of the family. A high level of privacy is therefore required in their use. This research studies the current state of sanitary zones in collective houses and in detached houses from a comparative perspective first, and then analyses the satisfaction and dissatisfaction requirement levels of dwellers of each house in comparison so as to provide data to formulate a new design for sanitary zones that is suitable for each dwelling house. The results of this research are as follows. (1) The questionnaire respondents were mostly in their 30s and 40s (99.1% in total), and lived in a nuclear family system (87.7%). (2) The number of sanitary zones was found to be more than 2 in 62% of collective houses and in 60.7% of detached houses, which leads us to conclude that non-dwelling spaces are increasing in both types of houses. (3) Of the housing facilities,13% of collective houses and 9% of detached houses were equipped with a bidet. Both percentages are very low but it needs to be noted that the percentage is relatively high in collective houses. In safety facilities, the ratio of houses furnished with safety handlers for the aged was very low in both types of houses. (4) The residents of collective houses showed high levels of dissatisfaction with regard to the problems of storage space and steam production, while residents of detached houses expressed high levels of dissatisfaction with regard to the heating system, colors of finishing materials, size, dampness, steam production, and storage space.

The purpose of this study is to clarify the spatial changes that have taken place in the main rooms (Anbang) and kitchens of traditional Utbangkkeokeum houses in Cheongju city, located on the central inland of Korea. These houses consist of a main house (Momchae) and a single-wing house (Nalgaechae), creating an ㄱ-shaped plan. The kitchen is in the front of the Nalgaechae, and the Anbang is at the rear. For the Momchae, the main hall (Daechung) is next to the Anbang, which is at the end of the Nalgaechae, and the room (Gunnunbang) is situated across from the Daechung. This study is based on the assumption that these houses have been conserved and altered from their original forms. As a result of alterations, many changes have occurred to the main room and kitchen spaces. The traditional main room is connected with two rooms (Utbang and Araebang), new standup kitchens are introduced, and floor heating systems are installed. The Anbang has maintained its sedentary lifestyle and the space for major daily activities such as sleeping and TV viewing. Also, TV viewing is a distinctive feature for residential purposes and the bedding is located in such a position that it is easy to observe any exterior movement for the elderly living alone. The layout of the standup kitchen has been altered to maintain the previous circulation, position and function of the entrance. Also, the kitchen and dining room were used together, and the size of these rooms has been partially increased from the original module in different ways for each case. The above findings suggest that Utbangkkeokeum houses of Cheongju city have been spatially changed while maintaining the previous lifestyle.

Although these days application of heat recovery ventilation and improved kitchen ventilation system came into wide use in mixed-use residential buildings and exclusive residences, there are not enough ventilation systems except the local ventilation of kitchens and rest rooms. It is very important part to regulate and distribute correct air flow rate for controlling air change rate. The purpose of this study is to investigate the application of distributor at house ventilation system by comparing a duct system with out distributor and with distributor. The results of this study are as follows. (1) When using distributor though the size of duct diameter is reduced rapidly, the pressure loss doesn't rise largely. The pressure loss without distributor is 4.08 mmAq, the pressure loss with distributor 4.10 mmAq. (2) To use distributor can reduce materials of duct and secure enough ceiling space by reducing duct diameter. (3) Diameters and air flow paths of distributor on the design stage are important part for accurate air flow rate.

Before occupation of an apartment housing, the builders are required to inform the test result of IAQ to the public. However, there is no simplified method to predict IAQ before measurement of pollutant concentration. In this study, a simplified way of predicting IAQ based on the distribution of indoor pollutant concentration is proposed. 7 different cases of air change rate have been simulated through CFD analysis to get the distribution ratio of each pollutant material and then simplified functions were used with CRIAQ1 values derived from CFD simulation to evaluate by comparing the influence of each material in the indoor pollutant concentration. Again, a lot of efforts which can improve the indoor air quality have been performed. Materials used in indoor space are labeled with their pollutant emission level. Installation of ventilation system in residential buildings will be regulated by a building codes sooner or later. But it is important to understand the fact that layout of walls, location or size of openings will influence the indoor air flow and pollutant concentration. And location of emitting material influences to indoor air pollutants distribution. But until now there is few recognition and consideration of these factors. Therefore, in this paper the effects of these factors is proved and some kind of guideline is made for designers after a comparison of typical apartment floor plan and a new type plan with their average pollutant concentration and its distribution of each room. CFD(Computational Fluid Dynamics) program was used to show the indoor air flow and pollutant concentration distribution. For this purpose, a typical $100m^2$ apartment floor plan was chosen as a case study model and several alternatives were reviewed to improve the IAQ performance. The simulation took place in the condition of natural ventilation through windows.

The purpose of this research was analysis of biotope structure focused on the evaluation for the nature experience and recreation in the case of Suseoung District in Daegu metropolitan area. The results of this study were as follows; 1) The result of biotope type classification was divided into 17 biotope type groups and 90 biotope types belonging to them. 2) In the result of the first evaluation for the nature experience and recreation, biotope types such as MA, NA, OE, PH, QB etc. possess great value. Particulary these biotope types come from forest areas and transition zone. The have not appeared in the inner of cities. 3) The biotope types such as JC, ME, OA, OE, PB, QD, QF etc. are proved to possess high value in the result of the utility evaluation. 4) There emerges 3a biotope type that has the highest value in the result of the second evaluation - such as ME, NB, NC, PD, QB etc. Most of them range widely except in the urbanized areas. Most of them were presented into the large area of site size and in the outer forest areas. But most of them were distributed in the forest areas intensively. So, it is certain that the space of nature experience connected with residential district of the urban people s scarce. Finally, the detailed plan must be made out specially continuously. It is about biotope spaces that are important for the nature experience and the recreation from the result of this research. Also, the study on the detailed index settlement of the sight green plan based on the biotope map must be continued.

The recent concept of kitchen is likely defined as "Kitchen Culture" including the function of living room where all families make a conversation as well as a dinner, and it is becoming another type of the residential environment, deviating from the stereotype as only cooking area. Particularly the comfortableness of living room is closely associated with a receipt function of kitchen, and the sort & dimension & size of furniture and diversity of shapes playa more meaningful role for improving our life standard & comfortableness compared with the past, nevertheless this receipt study is carelessly handled in the first phase of construction. This Study is focusing on understanding the modern concept of kitchen where the open space concept is being introduced as more reasonable space concept, and on suggesting a solution for receipt-function of the modern kitchen concept connected with "L-D-K (Living room - Dining room- Kitchen)" space idea. In the Chapter 2 the concept of receipt and function of kitchen, the wide variety of kitchen utensils was checked up, and in the Chapter 3 the change of trends of kitchen area & receipt space was considered, and finally in the Chapter 4 the modern concept of kitchen was presented, by instancing overseas examples with receipt planning. As a consequence, the alternative of the receipt in the modern kitchen is to install an Ireland table or another type of receipt-available table (lower furniture) in the dead space between kitchen & living room for motivating smooth communication and convenient receipt, and that is the trend nowadays. Kitchen desires a rapid change. Through this kind of study it should be more researched that kitchen is not an independent space any more and lies in the mutual connection of L-D-K.

The purpose of this study is to find out to meaning and practical use of 'Anbang' of which unique roles and function has not been changed till now since Chosun dynasty. The Study has been carried out by selecting 27 novels in which the word 'Anbang' mentioned frequently and analyzing the sentences with 'Anbang' . The major finding were summarized as follows: 1. Since Chosun dynasty till now, 'Anbang' in most important space for Korean in residential area its meaning and practical use had not been changed. 2. The meaning of Anbang could be categorized into two parts; One was general symbolic meaning which was perceived mentally in general and the other was specific symbolic meaning which was varied by uses. In case of general symbolic meaning 'Anbang' implied a space with light turned on late at night, a very special space from the point of interior decoration and size, a space to keep very important stuffs and a space to deal with very important business. In case of specific symbolic meaning during Chosun dynasty, 'Anbang' was used as a pronoun to imply a mistress as major occupant was a mistress. Since then, gradually, 'Anbang' was used as a pronoun to imply married couple as married couple becomes major occupant. 3. The practical use of 'Anbang' cold be categorized into two; One was routine usage and the other was exceptional usage. The typical routine use were sleeping, dining family gathering, visitor greeting, clothes changing and sewing. The exceptional use were a Sebae(new year's bow), Pyebaek(make a deep bow and offer her gifts to her parents-in-law) and patient curing.

The purpose of this research were to find ways to detect ecotone between the Mt. Pukhansan National Park and adjacent urban residential areas, to measure the width and size of ecotone around the park, and to investigate temporal change of ecotone around the Park. Normalized Difference Vegetation Index(NDVI) derived from TM data (May of 1985, 1987, and 1993) and the analytical capabilities of GIS were used to investigate the impacts of human activities inside of and outside of the boundary of the park. Major findings of the study can be summarized as follows: First, ecotone around the boundary of the national park could be identified from NDVI-distance curves derived by a series of buffering operations with a GIS. Second, average width of ecotone around the park was nealy doubled during 1985-1993 period. Third, NDVI vaules of the park were about 14 percent higher than those of surrounding areas. Finally, it seems that the expansion of the ecotone of the park is related to heavy trampling of visitors and various types of environmental pollution of the adjacent urban areas.

According to the recent "Status of Industrial Accidents at the End of December 2020" released by the Ministry of Employment and Labor, each industry is subject to industrial accidents. The number of accident deaths by construction industry, accident deaths by accident type fell, and accident deaths by workplace size were 5 to 49, indicating that most accident deaths occurred due to falling accidents at small construction sites. Therefore, urban living houses are small construction sites, and the probability of falling accidents is very high. Fall simulation training for disaster occurrence is conducted mainly by large construction ordering organizations in the public sector, and it is the first case in Korea that a housing construction company has conducted at a small construction site. This study analyzed and presented the definition, construction characteristics, and safety management status of urban living houses, and developed and spread an emergency relief procedure manual in the event of a fall accident to minimize deaths.
