$Fr{\ddot{a}}nkel$ functional regulator have a complicated design and are of a big bulk. This makes not only the construction of appliance but also the adaption of a patient to the appliance very difficult. Therefore, orthodontic laboratory technicians should be well acquainted with the sequential fabrication procedures involved in the construction of Frankel functional regulators and construct a type most suitable for a specific patient of malocclusion. There are various types of Frankel appliances. Detailed construction procedures of FR II are described here below, which can also be applied for other types for FR appliances.

This paper proposed a effective priority selection algorithm named weighted round-robin algorithm and show the implementation result of DMAC priority selection module using prosed weighted round-robin algorithm. I parameterize timing constraints of each functional module, which decide the effectiveness of system. Proposed weighted round-robin algorithm decide the most effective module for data transmission using parameterize timing constraints and update timing parameter of each module for next transmission module selection. I implement DMAC priority selection module using this weighted round-robin algorithm and can improve the timing effective for data transmission from memory to functional module or one functional module to another functional module.

This research aimed for 20 latter man whose body shape of torso alters remarkably to develop nipper pattern of running type considered characteristic of body shape of 20 latter man to keep rather balanced body shape against middle age when body shape changes extremely. 1. running type nipper pattern design. Pattern of running, lining and nipper were designed by flattening surface shell. A basis line of running pattern is completed by applying reduction ratio after 3 times of modification & complement based on surface shell. Nipper pattern is designed with design line set by a plaster cast based on running pattern line. Lining pattern is designed with lining design line set by a plaster cast based on running type outside material and nipper pattern. 2. Functional evaluation of research and commercial nipper. Functional inspection through dress test was applied 5point evaluation method and the result of functional inspection on the sight of a wearer is that research nipper(running reduction ratio 15%, nipper reduction ratio 18%) averaged more 4.8point but commercial nipper averaged less 1.8point in the aspect of 20 items such as wear sensibility, motional function and external appearance aesthetic. Research running type nipper scored high in order of motional function, looks of side, back, front and whole and wear sensibility. Functional inspection in the point of view of an observer is that research nipper(running reduction ratio 15%, nipper reduction ratio 18%) averaged over 4.8point and commercial nipper averaged under 1.9point in 17 items of external appearance beauty. Research running type nipper marked high in order of looks of back, whole, front and side.

Purpose : The purpose of this research is to find clinical effects of functional resistance training using weighted vest on gross motor and balance abilities of children with dyskinetic cerebral palsy. Methods : This study selects 3 subjects for 8~12 years old who were diagnosed with children with dyskinetic cerebral palsy. The Design is ABA design of single-subject research design. Baseline(A) and TypeII Baseline(A : 12weeks) phases were received with NDT treatment, Intervention(B : 12weeks) phase provided with 40 minute functional resistance training using weighted vest in a session twice a week. In order to analyze the measure results of gross motor function and performance, balance abilities in children dyskinetic cerebral palsy during baseline, intervention and typeII baseline phase. Result : A statistically significant differences in the total GMFM including walking/running/jumping during baseline, intervention, typeII baseline, but no significant differences in the lying/rolling, sitting, crawling/kneeling and standing. A statistically significant differences in the total GMPM including dissociated movement, coordination, weight shift, stability during baseline, intervention, typeII baseline, but no significant differences in the body alignment domains. A statistically significant differences in the length and surface area ellipse of center of pressure during baseline, intervention, typeII baseline. Conclusion : The intervention method to facilitate multi-joint and closed kinematic chain movement equipped weighted vest applied functional resistance training on children with dyskinetic cerebral palsy effectively improve on gross motor function and performance, balance abilities.

This study aimed to suggest a 1300 scale of a middle school foodservice facility floor plan which was compliant to the principle of HACCP, as well as ensuring food and work safety, and the flow of personnel and food materials. which consisted of 46 nutrition teachers and 6 experts, responded with a questionnaire on the relationship of functional area and space. Using their opinions, key principles for the design of the facility were single direction movement of food materials, customers and workers; minimization of the cross-contamination through the separation of functional space; and securement of customer-focused efficiency; staff-centered convenience and efficiency; and work and food safety. After the completion of an adjacency diagram, bubble diagram and program statement, the functional areas of a 1300 scale middle school food-service facility were allocated as follows: $9.9\;m^2$ for the receiving area, $56.1\;m^2$ for the pre-preparation area, $10.5\;m^2$ for the food storage area, $6.0\;m^2$ for the supplies storage area, $97.8\;m^2$ for the cooking area, $33.6\;m^2$ for the service area, $52.5\;m^2$ for dish washing area, cafeteria $410.5\;m^2$, $4.5\;m^2$ for the front room, for a total of $725.8\;m^2$. Expert groups have pointed to limitations within this model as there are no windows in the office for the influx of fresh outside air and a need for the straight line installation of steam-jacket and frying kettles on the sides of windows. This study can be useful as the guidelines for estimating the investment cost of the facility and placing the placement of functional areas and equipment in the renovation of the facility. It can be also useful data for a methodology of foodservice facility design.

최근 시스템의 규모가 커지고 복잡해지면서, 시스템 수준에서의 기능 검증방법론이 중요해지고 있다. 기능블록의 검증을 위해서는 주로 BFM(bus functional model)이 사용되며, 기능 검증에 대한 부담이 증가할수록 올바른 검증환경 구성의 중요성은 더욱 증가한다. SystemVerilog는 Verilog HDL의 확장으로 하드웨어 설계언어의 특징과 검증언어의 특징을 동시에 갖는다. 동일한 언어로 설계기술, 기능 시뮬레이션 그리고 검증을 진행할 수 있다는 것은 시스템개발에서 큰 이점을 갖는다. 본 논문에서는 SystemVerilog를 이용하여 AMBA 버스와 기능블록으로 구성된 DUT를 설계하고, 계층적 테스트벤치를 이용한 검증환경에서 DUT의 가능을 검증한다. 기능 블록은 Adaptive FIR 필터와 Booth's 곱셈기를 사용한다. 이를 통하여 검증환경이 DUT와 연결되는 인터페이스의 부분적인 변경을 통하여 다른 하드웨어의 기능을 검증하는데 재사용되는 이점을 가지고 있음을 확인한다.

심해저 망간단괴 집광시스템(이하, 집광시스템)의 개념설계가 공리적 설계(Axiomatic Design)의 관점에서 평가되었다. 또한 이미 수행된 집광시스템의 개념설계에 대해 기능적 영역의 기능요구와 물리적 영역의 설계파라미터가 구체화되었다. 기능요구와 설계파라미터의 상호관계는 첫 번째 수준 계층에서 하위 수준 계층으로 순차적으로 분석되었다. 이러한 상호관계는 설계행렬의 형태로 표현되었고 기능요구와 설계파라미터 사이의 독립성을 판단하기 위한 지표로 사용되었다. 설계행렬의 분석결과 본 집광시스템은 설계파라미터간에 연성이 되지 않는 비연성화된 설계임이 확인되었다. 결과적으로, 본 집광시스템은 독립공리(Independence Axiom)를 만족하는 잘된 설계임이 개념적으로 입증되었다.

The need for high-strength, multi-axis, and multi-functional machine tools has recently increased because of part complexity and workpiece strength. However, most of the machine tool manufacturers rely on experience for a detailed design because of the shortcomings in the existing design technology. This study uses a topology optimization method to more effectively design a large multi-functional machine tool considering static stiffness. The ram, saddle, and column parts are important structures in a machine tool. Hence, they are selected for the finite element method analysis. Based on this analysis, the optimized internal rib structure for those parts is designed for desirable rigidity and weight. This structure could possibly provide the required design technology for machine tool manufacturers.
