To improve stability of the water resources that were seriously affected by climate change and various environmental effects and to supply the clean water always, continuous efforts are essential. Provision of measures with respect of hardware is basically essential to improve the water resources stability due to the topographic characteristic in Korea. However, building a new dam becomes gradually very difficult because of a hardship in selecting right places, opposition forces such as environment and local residents, negative publicity for large civil engineering projects, and so on. The present study, therefore, proposes the Blue dam as an alternative for securing the water resources of a new concept considering domestic conditions. To evaluate the effect of the Blue dam, the Hec-ResSim model is used and the probabilistic discharge flow rate is applied. As a result, when Dam Yeongcheon is applied as a study area, securing water resources of 14 million tons are predicted be secured and the flood control of 15.4 million tons is expected, in comparison with operation of the existing dam only. Consequently, Blue dams are supposed to carry out the function of securing water resources, controling flood, maintaining eco-environmental instream flow, generating hydroelectric power, and providing spaces for recreational activities.

적도 서태평양에 존재하는 심해저 탄산염 퇴적물(시주공번호: DSDP 288과 289)에 대한 물리적 성질(밀도와 공극율), 음향학적 성질(속도와 속도성분 차이의 비), 그리고 전기적 성질(전기저항도와 전기저항 성분차이의 비)에 대한 실험실적 연구를 퇴적물의 속성작용의 관점에서 행하였다. 전기저항도의 깊이에 따른 변화는 속도의 변화양상과 거의 일치하며 전기저항도가 속성작용을 결정할 수 있는 변수의 하나가 될 수 있음을 보여주었다. 처트나 규산질 석회암 지대에서의 음향학적, 전기 적 성질의 급격한 변화는 호층을 이루는 규산염광물 때문에 공극의 모양이 크게 변 함에 기인함을 시사한다. 규산염광물 때문에 만들어진 여분의 탄산칼슘이 주변의 공극사적 상질이 크게 변하는 중요한 이유의 하나라고 생각된다. 이러한 자료는 규 산염광물의 속성작용이 탄산염퇴적물의 속성작용을 가속화시킨 결과로 해석된다.

기존의 산업단지 개발은 대규모 단일 공간 집적형태로 신규 부지를 활용하여 개발하는 방식이나 4차 산업혁명 시대는 스마트한 기술적용과 융복합화를 지원할 수 있는 새로운 입지모델 개발이 필요하다. 따라서 본 연구에서는 새로운 산업단지 공급유형으로 단일공간에 대규모로 집적하는 형태가 아닌 다수의 공간에 분산 배치하여 연계하는 방식으로서 '네트워크형 산업단지'를 제시하였다. 새로운 입지모델 개발을 위해 기업체 설문조사를 실시한 결과, 약 89%의 기업이 네트워크형 산업단지의 필요성을 인식하였으며, 동 산단의 활성화를 위한 조건으로서 '상호 보완기능형성', '결절지간 교통편리성'을 선택하였다. 네트워크형 산업단지는 도시공간과의 개방 연계 지향 및 기반인프라 공유 등을 통해 저비용 고효율화 산단으로 기능할 것으로 전망된다.

사회 각 부문의 이분법적인 분화가 근대성의 특징이었다면, 탈근대성 혹은 포스트모더니즘에서는 경계가 소멸되고 다양화되는 탈분화가 진행된다. 최근의 박물관들은 단순히 유물을 보관하는 근대적 공간에서 벗어나 여러 가지 사회문화적 요구를 수용하는 기능적 공간으로 탈근대화 되고 있다. 근대적 공간으로 탄생한 한국의 박물관이 문화 경관으로서 탈근대화 되는 양상을 알기 위해서는 역사적 형성 과정을 살펴보는 것이 필요하다. 이에 본 연구는 한국 박물관의 역사적 변천에서 나타나는 근대성과 탈근대성을 분화와 탈분화의 관점에서 살펴보았다. 이를 위해서 설립 주체의 유형별 변화를 토대로 한국 박물관의 역사적 변천과정을 근대적 박물관의 설립기(1945$\sim$1974), 탈근대적 박물관의 설립기(1975$\sim$1989), 탈근대적 박물관의 확산기(1990$\sim$2003)의 세 시기로 구분하여 분화와 탈분화의 양상을 살펴보았다.

Light-shelf is one of the most efficient natural lighting systems due to the improved function of the inflow level of the outdoor natural light. However, the existing research on the light shelf limits to the rectangular parallelepiped space, so do not provide sufficient data for various shapes of spaces. Thus, this study aims at deriving proper plan and relationship of the light shelf through its performance assessment depending on the indoor space shapes and utilizing them as basic data of light shelf design. The conclusions are as follows : 1) for 6m space depth, standard intensity of illumination satisfaction depth has shown 8.3%~26.3% improvement through the adjustment of the angle and width when installing light shelf compared to no light shelf installation; 2) $-30^{\circ}$, $-20^{\circ}$ and $-10^{\circ}$ light shelves set by this study play only as a blind regardless of the shape of ceiling on the summer solstice, and it is unsuitable; and 3) this study has derived proper plan of light shelf upon space shapes based on energy reduction and indoor evenness. The study results provide expanded data of the performance assessment of the light shelves according to the different space shapes and light shelf factors, which serves as a basis of the light shelves designing.

The mapping of dark matter clustering from real to redshift spaces introduces the anisotropic property to the measured density power spectrum in redshift space, known as the Redshift Space Distortion (hereafter RSD) effect. The mapping formula is intrinsically non-linear, which is complicated by the higher order polynomials due to the indefinite cross correlations between the density and velocity fields, and the Finger-of-God (hereafter FoG) effect due to the randomness of the peculiar velocity field. Furthermore, the rigorous test of this mapping formula is contaminated by the unknown non-linearity of the density and velocity fields, including their auto- and cross-correlations, for calculating which our theoretical calculation breaks down beyond some scales. Whilst the full higher order polynomials remains unknown, the other systematics can be controlled consistently within the same order truncation in the expansion of the mapping formula, as shown in this paper. The systematic due to the unknown non-linear density and velocity fields is removed by separately measuring all terms in the expansion using simulations. The uncertainty caused by the velocity randomness is controlled by splitting the FoG term into two pieces, 1) the non-local FoG term being independent of the separation vector between two different points, and 2) the local FoG term appearing as an indefinite polynomials which is expanded in the same order as all other perturbative polynomials. Using 100 realizations of simulations, we find that the best fitted non-local FoG function is Gaussian, with only one scale-independent free parameter, and that our new mapping formulation accurately reproduces the observed power spectrum in redshift space at the smallest scales by far, up to k ~ 0.3 h/Mpc, considering the resolution of future experiments.

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.

The purpose of this study is to analyze the expression method according to the planning of townhouse and the healing method that affects residents for communicating with natural environment, in order to propose resident-focused communication with nature for healing. The results are as follows. First, the expression of nature elements can be divided into 'direct' and 'indirect' and healing effects through nature can be divided into 'body' and 'psychology'. The healing method of residents through nature was classified into physical and psychological healing through openness, familiarity, comfort, and stability. Second, as an expression method according to townhouse planning, the arrangement plan induced active communication with nature through the arrangement according to topography and a common garden. In terms of construction plan, a bigger window or door than that of other residential spaces was installed on a wall, ceiling or opening to directly bring the nature of outside visually for more communication. Third, with regard to healing methods of townhouse, 'openness' which reduces depression and increases self-esteem, expands the view of residents. 'Familiarity', the healing method that can relieve the fatigue of eyes and bring psychological warmth and comfort, makes us feel familiar through the pattern and texture of woods and stones that are natural materials. 'Comfort' which heals residents by creating an outside space and bringing the nature elements through a huge window can provide psychological healing such as eased tension in daily life as well as physical healing such as vitamin D synthesis and the recovery of physiological function. Also, 'Stability' gives a comfortable feeling by applying the colors of finishing materials inside or seeing the colors of surrounding nature as it is through big windows. Finally, in order to support the results of this study more objectively, a follow-up study conducting a survey on the residents of townhouse is needed.

This study is about user satisfaction of the Junior College Library based on its characteristics of space composition. For this, we studied characteristics of space composition targeting the libraries in colleges in Seoul and Gyeonggi-do. First, in case of study of characteristics of space composition for books and library data, student satisfaction for traditional and normal library areas was high. It means that the service based on library areas should start from normal library areas as well as there is a change about space as the type of data in libraries change to electric data and multimedia. Second, If we look at the space for a reader and a user, satisfaction for a normal reading room was high. we can also see that satisfaction for a computer room and a multimedia reading room was not higher but still high. Also, the reason why satisfaction for a multimedia reading room that provides various activities was high was that the complex of a library space is needed to provide users with various activities. Third, in case of space for programme function and meeting, satisfaction for the room of video information and the group study room was high. we can see that user satisfaction for the space got high basically when a user is satisfied with the proper information technology based on interaction Fourth, as a result of variance analysis of 3 spaces of Junior College Library and the services, the size of the space of service does not influence user satisfaction directly. Even the space is small, if it decorates variously like with a lighting for a user, a window seat to meet the nature of users and has specific factors such as space reservation using internet, user satisfaction is high. If we summarise the result of this study, to make user satisfaction for speace in a Junior College Library higher, not just we need to try to make it extend as a educational, a cultural place but we also need to accept the student's requirement that the space also needs to be extend as a complex cultural space.
