The purpose of this study was to find out awareness of the environment-friendly planning elements for residential unit space among practitioners. The respondents in this questionnaire survey were 140 practitioners in architecture and interior design field. The major findings of this study were as follows; most of the respondents were aware of the impact of indoor built environment on residents' wellness. In addition, the survey respondents viewed that the factors for planning environment-friendly high-rise apartments were represented by gardening and energy-saving while their perception on the concept excluded comprehensive components affecting residents' life quality. Over 50% of respondents had an experience of applying environment-friendly planning elements in their works, and high frequency appeared on the general planning elements which had been applied special awareness as pro-environmental features. The respondents considered environment-friendly planning elements as important. Specially, space planning and system were considered more likely important in interior design field. In application of environment-friendly planning elements, cost, lack of consumers' awareness of and underdevelopment of environment-friendly materials were of concern. Therefore, the consumer's cognition needs to be improved for wide application about environment-friendly planning element, and then consumers are willing to pay additional construction cost of environment-friendly apartments. At the same time, the current practice that housing developers pass the additional cost on to residents needs to be changed. Then, the quality of life in high-rise residential settings can be improved. More importantly, the exchange and development of the reliable information on environment-friendly planning elements need to be made, and technical support and long-term policy for the development are required. This research showed current status of knowledge and practice in sustainable planning of unit apartment and proved basic information for future direction.
The post-corona era is having a major impact on university campus life, and campus cultural life has undergone drastic changes. In the process of adapting to this change. The existing face-to-face learning method is converted to non-face-to-face learning, and kiosks representing campus self-service are increasingly used. Subsequently, in order to match the characteristics of public places such as university campuses and provide better self-service, there are no related studies considering UI design elements of kiosks and characteristics of kiosks. This study conducted a survey on Chinese university students considering the characteristics and usability of university campus kiosks through user interface design elements in terms of design by considering previous studies. The purpose of this study is to examine the relationship between color, icon, typography, which are elements of kiosk interface design, and convenience, reliability, and usability, which are characteristics of a kiosk. In this study, the design elements and characteristics of the unmanned self-service system kiosk UI used by students at four universities in Korea and China were set as the scope of the study, and related documents were organized and surveyed in Korea and China. Case analysis and comparison method Through the kiosk usage characteristics of 4 universities were derived.

This study analyzes the art and questions presented in the secondary school teacher certification examination from 2018 to 2024, according to the art and evaluation area and evaluation content elements presented by the Korea Institute for Curriculum and Evaluation. In order to achieve the purpose of the study, 159 questions from the art and appointment examination over 7 years were collected and the ratio of evaluation content elements was analyzed for each of the 7 basic subjects and fields. As a result of the study, the proportion of evaluation content elements in each of the seven basic subjects and fields is also balanced at a considerable level. In other words, from 2009 to 2013, 55(50%) evaluation content elements were presented, compared to 71(64.5%) evaluation content elements from the 2018 teacher selection test to the 2024 school year. Despite this improvement, 39(35.5%) evaluation content elements were excluded, so improvement measures were discussed.
Korea is having entered the Ageing Society since 2000 and expected to be the Aged Society by 2019. Proliferation of the nuclear families, attitude shift of supporting the senior people and higher participation of married women in public life as well as the steadily increasing senior population have caused the need for development of the facilities or housings for the senior people. This study is based on the assumption that the congregate housing as one of the options for those senior people who are healthy enough do not need the nursing home. For the questionnaire survey, the preference of 500 Korean pre-senior people on spatial planning elements of units for the senior congregate housing was investigated. The collected data are analysed using SPSS 10.0 for Windows to deduce frequency, percentage, average, Chi-squared test with cross-tabulations. The results of this study were as follows; Most of respondents preferred to the size of 11-15pyung(for single), 21-25pyung(for couple). The type of spatial composition was preferred one-room type(for single), 1-2 bedroom type with kitchen (for couple). And they preferred L/DK type. Also, they preferred furnished units not to bring their own furniture when relocating to the senior congregate housing, which was somewhat different result from previous studies. There were significant differences between preferred spatial planning elements and gender, income, and level of education.

The opening of high speed railway upgraded our land transportation speed limit, causing lots of changes including living and culture and also paving the way for stepping up the railway technology. However, it is also true that we had a limit to adopt the existing railway system structured for 150km/h to the new structure requiring a higher speed of approximate 300km/h due to technological, based on the time and experience. More importantly, heading toward a step of operating such a high speed railway system, it has been practically and quickly proposed that the railway needs high speed railway engineering, maintenance technology of parts of the vehicles to have a stable maintenance foundation and localization of major parts. Therefore, this study was intended to research the actual displacement characteristics in runningg on an actual track for the purpose of developing the protective and maintenance technology of springs and dampers, which are core parts among suspension elements of a high speed railway vehicle. For this, it was researched the actual vehicle test and its interpretation centered on primary spring, which is used for the suspension system of a bogie, body-body dampers and body-bogie yaw damper. Also, to analyze the displacement characteristics of suspension system in the actual conditions of high speed railway vehicles, a vehicle‘s dynamic characteristics was analyzed and interpreted. At the same time, a tester for measuring the actual displacement of such suspension elements was designed and attached to actual vehicles, to measure the displacements that occur in running it on the Seoul-Busan line, one of major lines serviced by KTX. The displacement data gained from the test with actual vehicles was analyzed for its displacement distribution depending on the service sections and frequency, with which the valuable data necessary for any potential breakdown or maintenance in the future could be obtained.

This paper develops a finite element model for studying occupant behavior of a mid-size truck equipped with a driver side airbag. The developed model simulates an occupant behavior using PAM-CRASH/PAM-SAFE in super computer SP2. The model is developed based on a sled test. A 50% hybrid dummy III is used for measuring head and chest accelerations and femur loads, and major injury coefficients such as HIC, CA and femur load. Inferior components such as foot rest, seat, kneebolster, crash pad, etc. are roughly modeled and defined by a rigid material model. And contact type II is used for detecting a contact with dummy. Contact type II definition uses force-deflection relationship of each body Such components as steering column which directly affect on the occupant injuy are modeled in detail and defined by an elastic-plastic material model. Airbag cushion is modeled using rivet elements. Airbag cover groove is modeled using rivet elements. Airbag tether is modeled as nonlinear bar elements. Airbag model has two vent holes to ventilating the exploded gas. Airbag is folded close to the real airbag folding procedure, and folded cautiously in order not to have initial penetration. A vehicle pulse acquired from 31mph frontal barrier test is used as input signal for the simulation. The simulation conditions are tuned to the sled test ones. The measured dummy accelerations and major injury coefficients, and filmed dummy behavior and airbag inflation process using high speed camera are compared to the simulation results to verify the developed finite element model.
The Precambrian amphibolites in the central Gyeonggi massif, Yangsuri, Gyeonggido and southeastern Okcheon metamophic belt, Mungyeonggun, Gyeongsangbukdo, Korea, were studied on the geochemical characteristics of major and trace elements, and discussed petrogenetically and geotectonically. The characteristics of major elements of the amphibolites in these study areas are igeous origin such as tholeiitic-, subalkaline and alkaline basalt. Geotectonic distinction diagrams of trace elements such as Ti-Zr-Y and Zr-Nb-Y show basaltic igneous activity of island arc and mid ocean ridge environment at central Gyunggi massif, and within plate environment at southeastern Okcheon metamorphic belt. This result shows that genetic environments of study areas are different. Especially, origin of amphibolites in central Gyeonggi massif is similar with that of western Gyeonggi massif but different with the amphibolites of Chuncheon area. Genetic environment estimated of fractional crystallization of plagioclase has no particular effect on the origin of magma because value of LREE is higher than that of HREE and Eu anomaly definitely don't be exposed.
The main point of this study is to find ways to prevent accidents at complex linear sections in advance by improving geometric structure elements that can be considered from the designing stage. Complex linear roads are consisted of sections where straight sections connect with curved sections or sections where curved sections connect with curved sections with relatively high possibility of accidents and accidents can be reduced through improving designing elements in these sections. Therefore, this study aims to develop accident forecasting model in complex linear roads and to clarify major elements affecting traffic accidents. The results of analysis showed that the groups are divided into a group less than 355m based on curve radius of 355m, a group whose curve radius exceeds 355m and a group whose incline exceeds -0.79 and a group whose curve radius is below 355m and incline exceeds -0.79 for straight section + curved section, and for curved section + curved section, it is divided into a group whose first curved section is less than 410m based on curve radius of 410m and the first curve is turning right and a group exceeding 410m and the first curve is turning left. The major variables common in 2 models are front curve radius and curve types(left, right), road surfaces, weather.
The high-rise building is a dramatic phenomenon and a powerful expression of architecture in the modern civilization. The architecture of these high-rise buildings has been developed with mutual contributions of architectural aesthetic form and advanced technologies. Architecturally the significant evolution of tall buildings from ancient towers is a "change of function" from some religious symbols to a commercial concept that has aesthetically become acceptable with the changing of modern society and culture driven by a technological evolution. Generally, this commercial function in the evolution of high-rise building is office where high-rise working style is simply a necessity to meet quantitative market demands since this style in major cities around world has been changed from low-rise to high-rise during the last several decades in influenced of the modern industrial society. To achieve optimum spaces with architectural aesthetics in the high-rise building, the design has become collaborative, requiring the input of architects, engineers, economists, and other consultants. Hence, architects must deeply understand the basic planning theories of high-rise buildings and try to find optimum planning between architectural aesthetics and other issues. For the approach, we can firstly start with measurement and analysis of the planning use situation for major planning issues of high-rise buildings in practice. Therefore, this study is to analysis Design Elements and to find commonly used planning strategies, tectonic, of high-rise building in practice. It will give a chance to confirm commonly used planning and then becomes the starting point of the planning development of high-rise buildings based on practical planning issues.
