  • Recently a concrete slab tracks are being constructed on roadbed in the Gyoeng-bu 2nd phase high speed railways. In respdnding to this trend, new design standards and track materials maintenance systems, based on the slab track material safety and usage perspective, are needed. This research provides a roadbed design criteria and the maintenance system. The proposed roadbed design criteria and the maintenance system are based on the developed analysis meathod of train/slab-track interaction. where the roadbed settlement and train speed are utilized as mediating variables. In the analysis, the dynamic response of train/slab-track interaction apply to various speeds and settlements. the roadbed settlement is shown in a sinusoidal shape of wave, the scope of the settlement occurrence presented in its wavelengths, include 6meters, 10meters, 15merwes, 20meters, 30meters. The train speeds involved are 50, 100, 150, 200, 250, 300, 350, 400kilometers per hour.

  • The purpose of this study was to evaluate current usages and situations of kitchen with regard to universal design concept in order to provide useful data to plan universally designed kitchen space for all family members. Previous studies for universal design and kitchen planning were reviewed and a checklist was developed to evaluate kitchen space based on universal design concept by researchers of this study. Also, all items in the checklist were reclassified by 5 universal design criteria(Supportiveness, Adaptability, Communicability, Pleasantness, and Accessibility) and analyzed sample kichens by the criteria. The 7 households with different characteristics*age, sex, degree of disability or aging, and number of family) were selected for case studies. The results of this study suggested several critical design points to establish directions or provide guidelines for further kitchen planning.

  • This research aimed to identify the characteristics of outdoor apparel market for new seniors. To achieve this goal, influence of new seniors' lifestyle and apparel purchase criteria of design preferences of outdoor apparel products were investigated. An online-survey was conducted targeting fifties who have bought outdoor apparel within one year. The collected data were carried out for factor analysis, independent sample T-test, and regression analysis by using SPSS 22.0. Results showed that new seniors' lifestyles were composed of appearance-orientation, well-being diet, well-being exercise, self-development, and challenge-orientation. Purchase criteria of outdoor apparels were factored out as practical, aesthetic, and social. Appearance -orientation and self-development affect aesthetic and social factors. Well-being diet influences all factors of purchase criteria. Challenge -orientation has effect only on social factor. Women favored round-and V-neckline more than men did as well as preferred half and 3/4 long for sleeve. Customers who value practical purchase criteria preferred half-sleeve, zipper, and button-closure designs. In contrast, customers who have aesthetic purchase criteria like round/V-neckline and cap sleeve. Social factor affected high neckline and vivid-tone color preference significantly. As outdoor design for new senior it is critical to introduce differentiation of outdoor brand with various designs combining functionalities of outdoor activities and style looking young and dandy, which is highlighted as trendy and casual, over current outdoor apparels' unified design.

  • 실험영역을 벗어나는 점에 해당하는 반응값 예측을 위한 최적실험을 고려할 때 실험에 필요한 받힘점을 위한 실험기준을 선택하는 경우 매우 신중하여야 한다. 왜냐하면 가정한 모형과 오차구도가 실험영역을 벗어나도 타당하다는 가정을 하여야 되기 때문이다. 따라서 기존문헌의 외삽최적의 실험기준을 이러한 상황에 맞게 설계될 수 있도록 수정하였다. 본 연구에서는 maximin방법을 적용하여 새로운 실험기준의 특징 및 강건성을 단순회귀모형과 이차회귀모형을 기준으로 검정하였다.

  • This study focuses on design tendencies in office buildings of public institutions after tightening up Korea's building energy performance criteria. Important office design criteria and recommendations pay attention to the issues such as building orientation, greening buildings, building form, space and envelop by intensifying building energy performance related laws, government guidelines and evaluation systems. The design tendencies explored in this research are as follows. Office buildings mainly face south and have various types of indoor and roof green spaces not for ecological reasons but for the rest. Building depth becomes thinner and atria are inserted into office buildings to improve daylighting and natural ventilation. Building cores are located on north or west and east sides acting as buffer spaces to reduce heat loss and to block solar radiation. Office building envelop design includes various creative ideas to control or utilize solar energy as like three dimensional or double structured skin and window size variation to cope with the intensity of solar radiation. Further, solar energy generation systems are integrated with building component such as roofs, sun screens and windows. This study demonstrates that government's reinforcement of the building energy performance criteria drives the change in design methods and approach.

  • As robotic technologies have become more actively utilized to automate many construction tasks, they have been able to improve the construction productivity, quality, and worker's safety on site. A new advanced system, Robot-based Construction Automation (RCA) system, is currently being developed. To accomplish RCA system effectively, Design for automation (DFA) should be performed in automation system developing phase. The performance criteria of this system are a major cause of design changes. It is required exhaustive review for development new system. This research analyzed the design changes of Climbing Hydraulic Robot system and Construction Factory (CF), being currently developed in the field of applied RCA systems. And the design change matters according to performance criteria in each system's design-by-step were analyzed. The purpose of this research is developing the performance criteria in the developing phase of RCA system, and then will be served as basis for system design in similar projects.

  • 국내는 유럽에서 널리 사용하고 있는 헬리컬 파일을 많이 사용하기 시작하였지만, 헬리컬 파일의 설계기준을 만들려고 하는 노력이 부족하여, 여전히 헬리컬 파일의 표준설계기준을 가지고 있지 못하다. 따라서, 본 연구는 현장에서 헬리컬 파일을 시공하고 재하시험을 실시한 후, 이전 데이터를 포함하여 신뢰도 분석을 실시하였다. 그 결과 매입 말뚝에 대한 도로교설계기준 식이 수정 Davisson 분석법과 연계하여 좋은 신뢰도와 일관성을 보여주었는데, 이 설계식의 저항편향계수가 '1.0'에 가까웠고 변동성도 '낮음' 수준을 보여 주었기 때문이다.
