과거에는 단순한 생리처리 및 위생공간이었던 욕실에 대한 기능이 현대에 들어서는 생활의 활력을 충전하고, 자신만의 욕구와 실현의 공간으로써 활용되는 다기능 공간화 되어 가고 있다. 이러한 의식주에 대한 소비자들의 새로운 욕구와 변화가 나타나면서 현재 '욕실' 공간에서의 행위와 요구사항을 파악할 필요성이 높아져 가고 있다. 많은 수의 한국인들은 욕실사용에 있어서 서양의 입식(立式) 샤워 방식 외에도 욕조 밖이나 대야 등에 물을 받아 사용하는 등의 욕실사용 행태를 나타내고 있다. 따라서 이와 같은 한국인의 독특한 욕실사용행태를 설계에 반영함으로써 한국인의 욕실문화가 고려된 욕실구조 도출이 가능할 것이다. 본 연구는 욕실공간에 대한 사용 만족도를 높이기 위해 한국인의 욕실사용 정황과 사용 중에 느끼는 불편함과 종합적 감정 등을 조사하여 욕실 사용자의 요구사항을 도출하며, 욕실 공간계획에 있어서 건강, 위생문제를 해결하는 공간이자, 현대인의 신체특징과 라이프스타일이 반영 가능한 기본적인 설계지침 도출을 연구목표로 하고 있다.

최근 4대강사업을 통해 국가 주요하천 인근에 약 357개소의 친수공원을 조성하여 국민의 휴식 및 레저공간으로 활용하고, 하천 환경 및 생태적 건강성을 높이고자 하였으나 실제 활용도가 저조하여 친수지구의 수를 297개소로 축소하고, 친수지구 계획 및 관리를 위한 노력을 많이 하고 있다. 특히 이용객 수 조사 및 예측을 좀 더 과학적이고 체계적으로 하기 위해 통신 빅데이터를 활용하는 시도가 이루어지고 있다. 하지만 기존 사람이 현장 조사를 하는 방식과 비교하여 통신 빅데이터를 활용할 경우 공간적인 이용객 이동 패턴을 간편하게 파악할 수 있지만 실제 이용객 수와는 차이가 있기 때문에 이를 해결하기 위한 다양한 검증이 필요하다. 이에 본 연구에서는 낙동강 하구에 위치한 삼락생태공원을 대상으로 통신 빅데이터를 활용한 이용객 이동 패턴과 무인기를 활용한 이용객 수를 비교하여 통신 빅데이터를 활용한 이용객 수 추정의 정확도를 평가하였다. 그 결과 하천 친수지구의 경우 pCELL의 정밀도가 낮아 시설물별 이용 패턴을 정밀하게 추정하기 어려웠으며, 도로 및 주차장 등에 멈춰 있는 신호들 때문에 공원 내 이용 패턴이 왜곡될 수 있음을 확인하였다. 따라서 향후 통신 빅데이터 처리에 있어서 친수지구 내 pCELL 수를 확충하고 도로 및 주차장 등의 시설물을 제외한 이용객 수 추정할 수 있도록 개선이 필요한 것으로 나타났다.

Rapid industrialization and urbanization caused by the high economic growth of the country requires optimization of land usage as well as the expansion of underground space. Therefore the construction of large and deep basements is inevitable in built up areas where the braced excavation for earth retaining structures may create many problems such as settlement and damages of nearby buildings and underground utilities. In this work, some of major influential factors concerning the stability of braced excavation are investigated and the results are compared with the field observation results. The ground water table, applied strut forces, horezontal wall displacement, infilling materials in the rock joints were found to be the most critical factors influencing the stability of braced walls constructed in the layered ground. Magnituide and type of the wall deformation was closely related to the pattern of the surface settlement. The stability of braced walls are described in terms of strut forces.

With development of information technology and necessity for high security, using different identification methods has become very important. Each biometric feature has its own advantages and disadvantages and choosing each of them depends on our usage. Retinal scanning is a bio scale method for identification. The retina is composed of vessels and optical disk. The vessels distribution pattern is one the remarkable retinal identification methods. In this paper, a new approach is presented for identification via retinal images using LBP and hog methods. In the proposed method, it will be tried to separate the retinal vessels accurately via machine vision techniques which will have good sustainability in rotation and size change. HOG-based or LBP-based methods or their combination can be used for separation and also HSV color space can be used too. Having extracted the features, the similarity criteria can be used for identification. The implementation of proposed method and its comparison with one of the newly-presented methods in this area shows better performance of the proposed method.

The purpose of this study is to identify the problems that a current day care center has by analyzing the space arrangement, and to come up with the suggestion that would improve the arrangement along with the interior design of the day care center by studying the usage of materials, colors, lightings and furniture. The result of this study to follow problems were identified. 1. Classrooms also served as sleeping areas, therefore those two areas needed to be separated. 2. The kitchen was too small for the number of children. So they need separated kitchen and dining room. 3. The day care center remodeled from the ordinary house was wrose than other facilities in material, color pattern and design for child-care. 4. A lot of fluorescent light and bulb were used without enough windows to let natural sunlight in. 5. The restroom was so small that it caused uncomfortability to children. Based on the problems above, we could reach to a following conclusion. Use of primary colors could brighten the image of a room, and feature or creative arrangement of furniture may make it intriguing. With the increase in the expectation and attention to the young kids, the facilities should change according to them and be designed for the children. It is needed to study about whether the space and the elements of the emotional image were applied properly.

Most residential buildings in Korea are preferred to have maximum interior spaces, rather than consider its original design, overall building performance, and any other aspects since early 1990's. Especially in high-rise apartment buildings, balcony has been merged to living room to get more interior spaces and this renovation trends have been producing deep and narrow shapes of living rooms that was not initially intended by architects. On the other hand, the same gross area of each unit does not necessarily mean same width and depth ratio of each residential unit. Generally, we can categorize it to the deep or wide unit based on its width and depth ratio. Under these circumstances, this study analyzes the room usage pattern changes based on the space width and depth ratio and the effect of expansion of room space to the balcony. This study also includes about 180 apartments plan case studies to find out the relationships among w/d ratio changes, furniture arrangement types, and room configurations. In this research, general apartment room w/d ratios are 0.97 ∼ 1.23; 0.7(south facing sitting room), 1.23(south facing bed room), and 0.95(north facing bedroom). But, after expanding room space to balcony w/d ratio increased as follows; sitting room become 1.31, general south facing bedroom become 1.23, and north facing bedroom become 1.45. In addition to user preference of w/d ratio, many people prefer rectangular room shape a little(w/d ratio is 0.9 or 1.2) than square style (w/d ratio is 1.0) or very deep room style (w/d ratio Is more over 1.5). Accordingly, expanding the room space to balcony may make unsatisfactory room w/d ratio. Expanding room space to balcony should be considered by existing room w/d ratio.

패턴 분류에 많이 사용되는 기법 중의 하나인 메모리 기반 추론 알고리즘은 단순히 메모리에 저장하고 분류 시에 저장된 패턴과 테스트 패턴간의 거리를 계산하여 가장 가까운 학습패턴의 클래스로 분류하는 기법이기 때문에 패턴의 개수가 늘어나면 메모리가 증가하고 또한 추가로 패턴이 발생할 경우 처음부터 다시 수행해야하는 문제점을 가지고 있다. 이러한 문제점을 해결하기 위하여 이미 학습한 대표패턴을 기억하고 새로 들어오는 패턴에 대해서만 학습하는 점진적 학습 방법을 제안한다. 즉 추가로 학습패턴이 발생할 경우 매번 전체 학습 패턴을 다시 학습하는 것이 아니라, 새로 추가된 데이터만을 학습하여 대표패턴을 추출하여 메모리사용을 줄이는 iMPA(incremental Multi Partition Averaging)기법을 제안하였다. 본 논문에서 제안한 기법은 대표적인 메모리기반 추론 기법인 k-NN 기법과 비교하여 현저하게 줄어든 대표패턴으로 유사한 분류 성능을 보여주며, 점진적 특성을 지닌 NGE 이론을 구현한 EACH 시스템과 점진적인 실험에서도 탁월한 분류 성능을 보여준다.

In the era of globalization and unlimited competition, Korean universities need a breakthrough in their education system according to the changing education landscape, such as lower graduation requirements to cultivate more multi-talented convergence leaders. While each student has different learning capabilities, which results in different performance and achievements in the same class, the uniform education that most universities are currently offering fails to accommodate such differences. Blended learning, synergically combining offline and online classes, enlarges learning space and enriches learning experiences through diversified tools and materials, including multimedia. Recently, universities are increasingly adopting video contents and on-offline convergence learning strategy. Thus, this study suggests a teaching method based on blended learning to more effectively teach existing pattern CAD and virtual CAD in the Apparel Pattern CAD class. To this end, this researcher developed a teaching-learning method and curriculum according to the blended learning phase and video-based contents. The curriculum consisted of 2D CAD (SuperAlpha: Plus) and 3D CAD (CLO) software learning for 15 weeks. Then, it was loaded to the Learning Management System (LMS) and operated for 15 weeks both online and offline. The performance analysis of LMS usage found that class materials, among online postings, were viewed the most. The discussion menu most accurately depicted students' participation, and students who did not participate in discussions were estimated to check postings less than participating students. A survey on the blended learning found that students prefer digital or more digitized classes, while preferring face to face for Q&As.
