본 연구에서는 NATM으로 시공되는 산악터널의 시공과정에서 실측된 여굴, 숏크리트의 리바운드 및 투입율에 대한 분석을 실시하였다. 터널굴착 직후 굴착단면에 대한 여굴 크기를 조사한 결과 평균 여굴의 크기는 약 28.5cm 이며, 허용 여굴의 약 260%의 값을 보였다. 숏크리트의 리바운드는 평균 약 7.2% 정도로 측정되었는데 이는 일반적인 설계규정인 15% 보다 작은 값이다. 여굴 및 숏크리트 타설 중에 발생한 리바운드로 인하여 터널공사에 실제로 투입된 숏크리트 물량은 설계대비 약 116.5%의 값을 보였다. 자료분석에 의하면 숏크리트의 설계대비 실제투입율은 RMR(Rock Mass Rating)이나 터널 표준지보패턴과는 어느 정도 상관관계가 있는 것으로 나타났으나, 이에 비해 여굴은 RMR 값이나 표준지보패턴과는 상관성이 낮은 것으로 분석되었다. 따라서 표준지보패턴만에 의해 허용 여굴의 크기를 규정하는 현행 터널설계기준에 대한 재검토가 필요할 것으로 판단된다. 본 연구 결과를 통하여 분석된 여굴 및 숏크리트 투입량에 대한 고찰결과를 보고하고자 한다.

This study proposes an innovative design guideline to assist the evaluation and improvement of the dynamic comfort of vehicle seating. The existing evaluation method for the comfort of vehicle seating was investigated to broach problems in evaluation. It was found that the currently existing evaluation method employs the resonance frequency of the vibration system composed of the seat and the human body and the maximum vibration transmissibility. This study proposes a design guideline aimed at the enhancement of vibration transmission characteristics above the resonance range, particularly within the range of 10-18 Hz. In order to meet this guideline, a seat was constructed out of foam having a low damping coefficient. It was then installed in a vehicle for a driving test. The driving test confirmed the improvement of the dynamic comfort of the seat. The result of evaluation of the improved seat using the SEAT index, an industry standard widely used to evaluate the dynamic comfort of a seat considering the perceptivity characteristics of the human body, showed that the perceptive vibration transmission had reduced by more than $11\%$. The effect of the modification of seat foam was also verified through a subjective assessment of dynamic comfort of the seats.

As the structure of a mobile phone becomes thin to catch up with a slim product trend, the reliability of a LCD module is on the rise as a big issue for a product design. A drop test is the most basic and important verification method for a mechanical quality control but it requires much time and cost during a product development process. Thus many manufacturers have considered design guide lines using CAE and simulation for more effective usage of limited resources on the market. In this paper, the Maximum Principle Stress of a LCD glass panel is calculated on the basis of explicit FE Analyses method and input conditions are determined according to the general test standard. The design guideline for reliability improvements are suggested on the basis of the results of FE Analysis.

When designing a gear drive, designers should specify tolerances reasonably considering accuracy, cost, and manufacturing capability. In field design, however, designers mostly assign adequate tolerance without correlations between parts and assembly, resulting in iterative design dependent on experts know-how. In order to resolve this, the tolerance design system for a cylindrical gear drive is developed both to support tolerance design automation and to synthesize design processes of part and assembly tolerances. In this research, part tolerances are designed with the databases constructed by ISO, Ks, JIS and bearing catalogue, Assemble tolerance, that is, backlash tolerance is designed by synthesizing part design tolerances stochastically using the formulated assembly relations. This system can include part tolerance and fitting accuracy of shaft adn bearing in practical design. In addition, this system provides field-designers with a synthetic guideline for tolerance design of a gear drive.

The purpose of this study is to set the direction of development of the design guideline of the New-Hanok-Style public building in apartment complex and to use it as basic data for future architecture plans. The existing Hanok architecture standards and guidelines were analyzed and the characteristics of New-Hanok-Style Public Building in apartment complex were applied. The planning direction of the design guideline was derived. First, although the criteria and guidelines related to the Hanok produced and distributed were classified differently according to the purpose of production, the details and contents were similar. Second, the general planning criteria items were divided into layout, external space plan, building plan, and performance plan. Third, the elements of 'creative inheritance of traditional architecture' and 'modern building technology', which are the characteristics of New-Hanok-Style Public Building, were applied. In addition, we analyzed elementary welfare facility guidelines and applied elements such as layout type and zoning setting. Fourth, a special planning standard for applying the building system required for the New-Hanok-Style Public Building in apartment complex was added. In the future, it is expected to revitalize New-Hanok-Style Public Building containing the unique identity(genetic factor; DNA) of the nation by developing and disseminating relevant building standards, design guidelines, and maintenance manuals.

This paper reviews KSG2010(Korean Industrial Standard for Student's Desk and Chair) compared to student's body size and suggests its new design guideline. It is found that the chairs are too high to sit straight up, and it is not easy to sit at student's ease because of backbone rest bar not existed in a right place. It is also found that the desks are too high to sit at desk to accept student legs under a drawer. So student's visibility range becomes decreased and it produces a harmful posture for eye protection. This paper also found that step number of student's desks and chairs needs to expand to 12 different steps inserted 5 steps between the existing 7 steps. A reason is that there is gap between the sizes of desk and chair and human height and width. Another reasons is that it is difficult to arrange desks and chairs appropriated to student body sizes in a class room.

This research aimed to suggest a standard design that reflects Hanok design tendency, and present a selective design that can fulfill a building owner's intention beyond the simple function of building permit or report. In addition, this research attempted to become a standard by establishing a criterion in calculating the measurements of section design or primary framework members, in order to be a guideline for designing Hanok in different sizes and forms. The results are as follows. The building area of Hanok standard design was set to be below $85m^2$, with a straight type of $83.16m^2$ and an L-shape of $84.24m^2$. By dividing the plane into a straight type and L-shape, two straight types were suggested: 'general type' and 'large living room type.' The upper floor space, along with the main room and small room, was proposed as an option to be changed into a room where an underfloor heating is installed depending on the building owner's intention. In addition, a criterion for side design and calculation of framework measurements was suggested and applied, while a five-girder design without high pillars was suggested for material-assembling structure. Two types of pillars-circumference and square cylinder-were proposed for the building owner to choose from, and a pointed beam house and ikgong(orthogonally-projected bracket) house were suggested for pojak bracket structure so either of them could be chosen according to the building owner's taste and economic condition. Finally, the sectional size of main materials were divided according to the form of pojak bracket structure to be proposed.
