Planning and designing training facilities has been developed from educational facilities, and increasingly diversified society has raised a need for facilities dedicated to training and education in a differentiated space separate from the one for regular works. This particular need of our times has led to the expansion of training facilities nationwide although they have something to be desired when it comes to planning and designing with sustainability associated with the locational characteristics of urban space as well as the unique types of facilities taken into account. Against this backdrop, this study will examined a variety of training facilities that have been established since 2000 through theoretical review and conduct intensive analysis on the characteristics of the planning aspects to suggest their significance and implications and to present the overall meanings and ramifications of planning approaches in consideration of new challenges modern training facilities are faced with, which have been revealed through architectural design competitions in recent years. The relevant implications are as follows. First, one of the locational advantages of training facilities, which is commanding beautiful scenery of the surrounding area, can be considered as intent to stress the aspect of a resort, one of the functions of any training facilities. As this study has demonstrated, many training facilities are located near around a beach or a lake. Second, training facilities can be classified into three different types in terms of their location: urban, suburban and resort and such locational characteristics are directly related to intended programs and differentiated links with target users. Third, the architectural styles of training institutes are differentiated in terms of harmonious arrangement between beautiful natural scenery and buildings in consideration of the layout characteristics of major facilities and the distance of ramps in and out of the facilities along with architectural features, including the transparency of building elevation and the type of slopes of roof structure. Fourth, the individual lodging buildings feature a variety of types depending on the design concept with different roles depending on the directional aspects such as the connection of ramps and the relations with the outside. Fifth, outdoor space plans are differentiated according to the intended purpose of training facilities. When it comes to gym facilities, for example, different outdoor space plans are found to be made depending on the original design concept such as outdoor playground-centered planning or golf facilities.

최근 고속도로 본선구간에서 발생한 교통사고에 대한 연구가 다수 수행되고 있으나, 램프와 같이 본선 외 구간에 대한 교통안전을 다루는 연구는 미미한 실정이다. 최근 5년(2015년~2019년)동안 램프에서 발생한 사고는 총 6,717건으로 이는 전체 고속도로 사고의 약 15%를 차지한다. 본 연구에서는 고속도로 램프구간에 대해 보다 정확한 사고 예측 모형을 제공하기 위해 포아송 감마(PG)와 포아송 역가우스(PIG)와 같은 다양한 통계 분포를 비롯하여 랜덤효과와 같은 기법을 적용하여 Simple 및 Full SPF를 구축하고 비교하였다. 교통 및 도로 기하구조 데이터는 로드뷰와 같은 다양한 시스템에서 수집되었다. 분석 결과, PIG 모형은 일반적으로 더 정확한 사고 예측을 제시하며, Simpe SPF와 Full SPF 모두에서 임의효과 모형이 더욱 우수한 성능을 나타내었다. 본 연구결과는 교통실무자들에게 정확한 사고 예측 모형을 기반으로 램프구간 교통안전을 증대시키고 이해할 수 있는 참고자료로써 활용될 수 있다.

Truss-Z (TZ) is an Extremely Modular System (EMS). Such systems allow for creation of structurally sound free-form structures, are comprised of as few types of modules as possible, and are not constrained by a regular tessellation of space. Their objective is to create spatial structures in given environments connecting given terminals without self-intersections and obstacle-intersections. TZ is a skeletal modular system for creating free-form pedestrian ramps and ramp networks. The previous research on TZ focused on global discrete geometric optimization of the spatial configuration of modules. This paper reports on the first attempts at structural optimization of the module for a single-branch TZ. The internal topology and the sizing of module beams are subject to optimization. An important challenge is that the module is to be universal: it must be designed for the worst case scenario, as defined by the module position within a TZ branch and the geometric configuration of the branch itself. There are four variations of each module, and the number of unique TZ configurations grows exponentially with the branch length. The aim is to obtain minimum-mass modules with the von Mises equivalent stress constrained under certain design load. The resulting modules are further evaluated also in terms of the typical structural criterion of compliance.

The purpose of this study was to identify the characteristics of expressionism in the space of deconstructive architecture by comparing the spaces of "The Cabinet of Dr. Caligari" video with the expressionist characteristics of film narrative structure and expressionist architecture and making an expansion based on the results. The findings were as follows: first, the "The Cabinet of Dr. Caligari" is divided into two set spaces: one has the perspective representation distorted in the viewpoint of a mad person applied to it, and the other reflects the viewpoint of a normal person from medieval paintings with no perspective. Second, the expressionist buildings did not reflect the expressionist characteristics in the interior spaces as fully as in the exterior ones. Third, the incomplete combination of Signifiant and $Signifi{\acute{e}}$, which were the theoretical basis of deconstructive architecture, showed a tendency of binary opposition like the double narrative structure of "The Cabinet of Dr. Caligari." Fourth, deconstructive architecture seems to embody the exterior form and interior space of "The Cabinet of Dr. Caligari" and its set spaces in the phenomenal aspect but exhibits its limitations with the realization of dynamics, one of the characteristics of expressionism. Finally, the Seattle Public Library presents the best embodiment of expressionist characteristics found in the set spaces of "The Cabinet of Dr. Caligari" while seeking after the combination of horizontal and vertical paths of action through the spiral ramps and inclined slabs.

The purpose of the study is to analyze the planning characteristics of outdoor space in apartment complexes in terms of child-care environment. We selected 8 apartment complexes in Cheongju, within three years from construction, of small and medium-sized apartments ($60-85m^2$) where a large number of families with young children are presumed to reside in. As a result of the study, it was found that whereas the factors that can be quantified such as the floor height differences, the angles of ramps, and the number of the rest facilities are excellent, the qualitative part which cannot be easily quantified such as the location and direction of the rest facility and play materials should be improved a lot. And the following improvements were suggested; separating the pedestrian passage from the vehicle road in the main entrance of the complex, utilizing the piloti for infant caring, making the entrance area of apartment safe for pedestrians from vehicles, reallocating resting spaces, redesigning resting spaces safer to infants, building or reallocating existing booths at the stops of kindergarten buses, redesigning the square safer from vehicles with shades, making it possible for guardians to watch infants in playing field from the resting space, allocating natural environments essential for child development.
