본 연구는 미국 텍사스 주의 소도시에 있는 스캇 앤 화이트 클리닉의 외부공간을 대상으로 하여 외래환자와 방문객들이 직면하는 길찾기의 문제점을 분석한다. 연구의 공간적 범위는 클리닉의 외부공간으로 한정하여 진입도로에서 진입하여 주차한 후 출입구에 도달하는 경로에서 관찰되는 행태적 특성을 분석한다. 분석의 초점은 진입도로에서 이루어지는 경로선택의 결정과 그것이 클리닉에 진입하기 위한 출입구 결정에 미치는 영향관계에 둔다. 분석은 외부공간에서의 길찾기에 관한 기존 연구문헌을 참고하여 작성한 연구모형에 의해 이루어진다. 구체적으로 보면, 이용자들이 보이는 날씨, 성별, 그리고 나이에 따른 길찾기 행태의 차이를 클리닉의 남동측 출입구와 남서측 출입구에서 발생하는 이용자들의 하차 빈도를 측정하였다. 또한 하차의 위치를 행태 지도에 기록하여 연구모델에 나타나는 상관성을 분석하였다. 길찾기 행태분석 결과를 통해 파악된 외부주차장에 주차한 후 클리닉에 접근하는 이용자들의 경로선택의 문제점과 클리닉의 입구 공간에서 하차한 이용자들의 입구선택에서 나타나는 문제점을 토대로 하여 외부공간에서 발생하는 길찾기 행위의 효율성을 증진시키기 위한 디자인 추천 사항을 다음과 같이 제시한다: (1) 시각적 단서를 제공하기 위해 남서쪽 출입구의 형태와 색채 차별화; (2) 도로에서 클리닉 진입공간에 위치한 안내판의 글자 크기 확대; (3) 학습된 길찾기 행태를 보조하기 위해 동쪽에 랜드마크 시설물 설치 및 목적 지점의 최종경관 개선; (4) 과도한 클리닉의 정보에 의해 감소되는 가독성을 고려하여 안내판의 정보 간략화; (5) 색채의 대조를 고려(출입구 벽에 설치된 클리닉의 이름이 갈색에 푸른색으로 설치되어 있어 색채의 대비가 낮아 가독성 떨어짐); (6) 클리닉 중앙 출입구의 하차 공간 상부에 설치된 캐노피 기둥의 과도한 크기에 의해 발생하는 가시공간의 감소에 의해 발생하는 하차 공간 사용의 혼잡 문제를 제거하기 위해 기둥규모 축소; (7) 하차점 6까지 캐노피를 확장하여 우천시에 발생하는 공간 사용의 문제점 제거; 그리고 (8) 올바른 하차공간 사용을 위해 진입 접근도로에 차선 설치.

Recently, the expansion of smart phones, wi-fi. and unlimited service changed our life style from personal computer based to mobile device based. With this trend, a lot of companies and government facilities use QR code as an advertising material, and now the QR code is very popular service in our ordinary life. In the meantime, libraries in abroad and university libraries started using QR code in library service about 2 or 3 years ago, and domestic libraries started using it in service due to the increase of establishment of mobile Library websites. In this research, starting with looking into the literature, I analyzed the examples of the use of QR code in libraries. On the base of it, I drew a QR code library service model, and what needs to be considered for the use of it.

In level 3 automated vehicles, drivers are expected to encounter transition of control when the system reaches its limit. Drivers need to refocus their attention on the road ahead and gain situational awareness. Appropriate information should be conveyed during this period in order to prevent human errors. In this paper, we defined the takeover process as 'in-the-middle-of-the-loop' and conducted Task Analysis and Work Domain Analysis to find out information requirements. As a result, we specified required information types and interface considerations. Moreover, we conducted an experimental study to find how the information types affect drivers on situation awareness, cognitive load and reaction time. Consequently, we found different information on system transparency should be conveyed depending on the urgency of takeover situation and driver guidance could help drivers with better situation awareness after the takeover.

The purpose s of this study is to verify the status of barrier-free certification in an elementary school. To achieve this, the architectural characteristics of an elementary school and proposed opinions about the process of barrier-free certification were analyzed. The results of this study are as follows: (1) barrier-free certification in an elementary school is valid for inclusive education and accessibility for students with disabilities. (2) Regarding the school district and safe accessibility for the school, it is necessary to minimize the differences in land levels around the school. (3) Considering the opinions on intermediate facilities from the road to the main entrance, it is necessary to set the finish level of the first floor and to minimize the establishment of ramp or steps to prevent the backflow of rainfall.

The increased competition in service development in various industrial sectors highlights the importance of producing high-quality services that provide a positive user experience. Although usability evaluation is recognized as an important method of verification of high quality service and utility, the general usability evaluation method has limitations of not taking the characteristics of various participants due to its uniform composition to account. As the following flaws can reduce evaluation efficiency, developing a new guideline seems to be the next step. Thus, this study focused on criteria on how to evaluate the usability for children and proposed non-face-to-face remote usability evaluation configurations and progress guidelines to increase the effectiveness. The following usability evaluation experiment was conducted based on the proposed guidelines and in this process, the effectiveness of the guidelines was verified and the items that needed to be supplemented were derived. It is expected that the non-face-to-face remote usability evaluation guidelines proposed through the study will be used as the basis for designing usability evaluations of services developed for children.

The sensor network technology for core technology of ubiquitous computing is in the spotlight recently, the research on sensor network is proceeding actively which is composed many different sensor node. One of the important condition for design of sensor node is to extend for network life which is to minimize power-consumption under the limited resources of sensor network. This study suggest routing protocol that was used second level cluster structure to reduce power-consumption of sensor node. the first level use the previous routing protocol under the LEACH, second level decide to transmit or not by comparision of data value for Effective Usage, reduce the unnecessary power-consumption.

When we design a sensor nodes, a energy-consumption of sensor nodes centers on design concerns to prolong lifetime of sensor network. In recent year, many researches have attempted to study this issue. One of that is TTDD(Two-Tier Data Dissemination approach) proposed to support a sensor network which includes several mobile sensor nodes. But it gives rise to a problem which increasing control packet for the formation and maintenance a grid structure. Therefore, we proposed a Energy-Efficient Routing Protocol used a permanent grid structure for reducing control packets in a sensor network.

This study is intended to propose the environment friendly lighting which can be excluded the element of obtrusive light(glare, spill light) and to make the sight environment of the external and internal road more comfortable as newly approaching the lower positioned lighting from the current high pole lighting. Taking account of the current situation of putting the stress on the road sight scene. It is proposed the study focused on the aesthetic design for playing a role of scenery. For this, it is searched used situation of the low light at interior of the country and abroad and tried to find the improvement. Also it is tried find out how to raise the effectiveness. And throughout the site inspection and the data searching about the road facility of a road to be installed the low height lighting, it is suggested the standard of the lighting installation and the direction for the future on the light design and development of the low height lighting which is suitable for the domestic situation.

In order to meet the needs of integrated design process in architect industry, BIM(Building Information Modeling) education in university is urgently needed. However, the investigation of the current status of BIM education at 60 universities shows that most universities do not offer BIM education at all, or opened only one regular course for BIM education. The survey on BIM education for students shows that non-curricular activities brought bigger educational achievements than regular courses. Considering these findings and the practical restrictions of the universities, and through evaluation and feedback from professors as educational providers and working architects as professional users, the desirable strategy for BIM education in architect design was able to be suggested, which is consisted of regular curriculum of two courses and 40 hours non-curricular activities.
