In this study, the transient second or third layer on the topside of the Martian ionosphere were investigated with the most recently released Mars advanced radar for subsurface and ionospheric sounding/Mars Express data obtained from January 2010 to September 2011 to study the correlation between these topside additional layers and surface magnetic fields, solar zenith angle and solar activities. When examining the zones where the topside layer appeared, the occurrence rate of the topside layer was low at the areas with a strong Martian crustal magnetic field as observed by the Mars global surveyor. The occurrence rate of additional layers on the Martian topside ionosphere decreases as the solar zenith angle increases. However, these layers appeared significantly near the terminator of which solar zenith angle is $90^{\circ}$. In comparison between F10.7 which is the index of solar activities and the occurrence rate of the topside layer by date, its occurrence rate was higher in 2011 than in 2010 with less solar activities. The result of this study will contribute to better understanding of the environments in the topside of the ionosphere through the correlation between the various conditions regarding the Martian ionosphere and the transient layer.

As an apartment house as well as improving quality of life is becoming one of the brands, it is increasing the importance of the outer space with the facilities in the housing complex. In particular, the outdoor playground such as the community facilities that children and adults share as the activity areas for residents has received attention. However, actually children have not used many of Korean apartment housing playgrounds that were installed formally in the scrap area according to the housing plan by residential construction standards. it is considered necessary to improve the quality of the playground in housing complex and reform it in order to make the eco-friendly play space in which children can play safely and h healthily. As an alternative, we analyzed the eco-friendly properties of the playgrounds installed in the eco-friendly housing complex in Germany and derived the main planning elements of eco-friendly playground. In the observational survey of the 10 playgrounds in 9 housing complexes in 5 regions in Germany, we evaluated the environment-friendliness of these playgrounds in the 8 fields(location and placement, ecological environment, play space, play equipment and facilities, additional facilities, materials and resources, energy saving, environmental load reduction) according to the levels(suitable, partial reflection, unsuitable, non-reflection) of reflection of eco-friendly planning factors. The following is the summary of the results about the reflection of eco-friendly planning factors. In terms of "suitable": location and placement(88.8%), play equipment and facilities(73.5%), additional facilities(60.6%), environmental load reduction(54%), and ecological environment(50%) were higher than others. In terms of "unsuitable": there was nothing. In terms of "non-reflection": energy saving(95%), additional facilities(32.2%), and materials and resources(30.9%) were in order. Therefore, on the basis of these results, this study proposed the planning indicators to be considered first and the planning factors that should be complemented and improved in the construction of apartment housing playground in future.

Kitchen has been an essential space and plays an important role in the house regardless of culture and regional differences. However, due to social and economical changes, kitchen is no longer used only for preparing food and dining which seem to be a traditional function. The purpose of this study is to investigate the additional functions of the kitchen and figure out the related variables. The survey method was used to collect data from 321 housewives living in the apartment sized over 99$\textrm{m}^2$(30 pyung) in Ulsan. The data were analyzed by SPSS/$PC^+$ with frequency, percent, and chi-squared test. The results of this study were: (1) Kitchen was now used for eating snacks(45.6%), keeping household account(42.5%), and chatting(41.6%). (2) Homemakers wanted to do laundry such as ironing, drying clothes, and folding clothes in the kitchen. However, there were several activities(i.e., grooming, rest and taking a nap, exercise) they do not want to do in the kitchen. (3) The variables which related to the additional functions of the kitchen were size of the apartment, age, and level of education. The findings of this study imply that there must be design considerations for chatting and keeping household account such as providing tables and comfortable chairs. In addition, new counter layout types should be developed based on needs of additional functions and related variables.

터널의 갱구부는 토피가 얕고 지반의 아칭효과가 발휘되기 어렵기 때문에 터널 시공 시 주의가 필요한 구간이다. 공용 중인 터널 갱구부 상부에 추가적인 성토가 이루어진다면 터널 안정성을 크게 저해할 수 있다. 따라서 본 연구에서는 터널 상부의 추가 성토에 따른 터널 안정성을 검토하고자 지반조건별로 성토 높이에 따른 수치해석을 수행하였다. 해석 결과 5등급 암반에서 성토 높이가 12 m 이상인 경우에는 숏크리트의 허용 휨압축응력, 록볼트의 허용 축력을 초과하는 것으로 나타났다. 발생되는 변위와 소성영역의 범위, 지보재의 상태를 종합적으로 고려할 때 터널 갱구부 상부에 추가 성토되는 높이가 10 m를 초과하는 경우에는 터널 안정성이 크게 저해되는 것으로 판단된다.

This study is aimed at analyzing desired spaces and demands for their improvements, and subsequently proposing the design plan for eating and drinking places for solo diners by surveying the user satisfaction based on the analysis of the space configuration, and the physical environment of eating and drinking spaces for solo diners. Theoretical discussions about eating and drinking spaces for solo diners and their physical environment were reviewed from the previous studies, and an on-site survey was conducted with a checklist, for which the items regarding configuring elements of physical environments for the satisfaction with eating and drinking spaces for solo diners have been derived. Measurable checklist items according to the configuration of eating and drinking spaces were derived for this survey, which had then been conducted with diners in the eating and drinking spaces for 2 weeks. The analysis results are as follows. First, cleanliness is required as a necessity for the user satisfaction in eating and drinking spaces for solo diners. Second, a '-' shaped bar and the spaces to utilize and combine additional facilities are required in the central service space. Third, the self service should be performed in the additional service space. Fourth, the menu composition and the location selection considering main age groups of diners are needed. Fifth, interior design elements need to be improved to allow diners to feel visual interest along with enjoying food and beverage. It is considered that the strategies of spatial design need to be analyzed and proposed from the perspective of design among the physical environments of eating and drinking spaces for solo diners in future studies.
