The purpose of this study is to present the use of traditional culture and the direction of various fashion designs by developing and producing contemporary fashion designs on the Muslim costumes of the Chinese Hui minority. Based on research methods, the cultural background was investigated and the design characteristics were summarized. Based on the results of this survey, 4 sets of women's fashion were designed. The design intent was to feature Muslim traditional costumes and to adopt a functional contemporary design. The conclusions of this study are as follows. First, simple and indecisive clothing shows the innocent and good side of the congregation. In this study, traditional dresses were used to make use of the simple silhouette and color, and to create a contemporary atmosphere, various materials, such as wool, glossy industrial complex, lace, and fur were used to create a modern sense design by adding diversity to the simple silhouette. Second, the biggest feature of the regimented Muslim costume focuses on a head cover and suggests a contemporary sense of hood improvement, and a design that can be used with two sides. These hooded head covers can provide fashion and diversity and can be proposed as functional. Third, contemporary Muslim fashion is gaining global attention and it is possible to develop various fashion designs based on traditional motifs. This study was able to increase the feminine image by changing the solemnity of the communal dress without discarding the foundation of the traditional religious culture based on the daily dress of the people.

The steel outfitting structures installed in engine room are vibrated by an excitation of the engine and the propeller. Vibration problems such as cracks and fitting breakages are mainly induced at the near range of the resonance. The excitation frequency estimation is possible by engines and propeller specifications, but the natural frequency of a steel outfitting structure is not easily estimated due to the complication and variety of the designed shape. This paper represents natural frequency data of simple steel outfitting structures. As a vibration analysis tool, MSC/NASTRAN was used to calculate natural frequencies. Natural frequencies were compared in case of the shape and boundary condition changes of simple models, and anti-vibration models of the steel outfitting structures were presented on the basis of results.

Background: The present study introduces the design and fabrication of a simple surgical guide with which to perform genioplasty. Methods: A three-dimensional reconstruction of the patient's cranio-maxilla region was built, with a dentofacial skeletal model, then derived from CT DICOM data. A surgical simulation was performed on the maxilla and mandible, using three-dimensional cephalometry. We then simulated a full genioplasty, in silico, using the three-dimensional (3D) model of the mandible, according to the final surgical treatment plan. The simulation allowed us to design a surgical guide for genioplasty, which was then computer-rendered and 3D-printed. The manufactured surgical device was ultimately used in an actual genioplasty to guide the osteotomy and to move the cut bone segment to the intended location. Results: We successfully performed the osteotomy, as planned during a genioplasty, using the computer-aided design and computer-aided manufacturing (CAD/CAM) surgical guide that we initially designed and tested using simulated surgery. Conclusions: The surgical guide that we developed proved to be a simple and practical tool with which to assist the surgeon in accurately cutting and removing bone segments, during a genioplasty surgery, as preoperatively planned during 3D surgical simulations.

The purpose of this study was to investigate the sensation seeking tendency and knitwear purchase behaviors of high school girls. The data were obtained from 475 high school girls at 6 high schools located in Daejeon. The method of study is a survey consisted of sensation seeking tendency items, knitwear purchase behavior items and demographic attribution. Data were analyzed by frequency, variance, crosstabs, and correlation analysis using SPSS WIN 17.0 program. The results of study are as follows. First, high school girls generally liked knitwears by reason of comfort and activity. Most girls purchased the knitwears to wear ordinary casual wear(81.5%). They usually thought sweater and cardigan to be representative of knitwears. Also, they mostly purchased the knitwears of simple and active design, achromatic color, 100% cotton, and solid or simple stripe pattern. The design and price were considered as important evaluation criteria in knitwear purchase. The information sources used by them were store display, friends, and internet. Second, the knitwear purchase behaviors of high school girls showed the difference between groups with high- and low-sensation seeking tendency. The most important factor of knitwear purchase was an unique and characteristic design in high group and a simple and active design in low group. In conclusion, high school girls liked knitwears and had different knitwear purchase behaviors according to the sensation seeking tendency.

One of the methods to simplify the design process for a fuzzy logic controller (FLC) is to reduce the number of variables representing the rule antecedent. This in turn decreases the number of control rules, membership functions, and scaling factors. For this purpose, we designed a single-input FLC that uses a sole fuzzy input variable. However, it is still deficient in the capability of adapting some varying operating conditions although it provides a simple method for the design of FLC's. We here design two simple-structured adaptive fuzzy logic controllers (SAFLC's) using the concept of the single-input FLC. Linguistic fuzzy control rules are directly incorporated into the controller by a fuzzy basis function. Thus some parameters of the membership functions characterizing the linguistic terms of the fuzzy control rules can be adjusted by an adaptive law. In our controllers, center values of fuzzy sets are directly adjusted by an adaptive law. Two SAFLC's are designed. One of them uses a Hurwitz error dynamics and the other a switching function of the sliding mode control (SMC). We also prove that 1） their closed-loop systems are globally stable in the sense that all signals involved are bounded and 2） their tracking errors converge to zero asymptotically. We perform computer simulations using a nonlinear plant.

As regards of designing, I chose a simple wall design of repeating pattern of vertical windows, rather than making the building as a glamourous obzet. This kind of approach was intended to pursue strong image of construction company, interchanging and communicating with its confused surrounding. Therefore, I boldly removed parts that I considered needless from the facade, and used simple and easy words clearly implying the organization. Lobby is the face of the building, but since the space is deep and narrow and the reality of lease should be considered, there was limit to give original image to the lobby. Instead, high ceiling is the biggest feature of this space. Doorae Engineering-Construction Corp. is young and energetic company. I wanted to highlight the young and energetic image of the company by crossing tore oblique piece of boards. This doesn't just has a simple function as ceiling, but also work as a major subject in the space. In addition of this powerful space of oblique lines, indirect lighting is used to emphasize the character of territory, continuity and deepness of the space. Character of territory that divides main and supplementary function and main and supplementary moving line is expressed by flow of dimension, and continuity and deepness of space is emphasized by indirect lighting flowing linearly through the crack between the ceiling and the wall.

A hybrid electromagnetic actuator with an air spring is designed so as to achieve the desired isolation reduce the vibration efficiency on the floor vibration. The performance specification of the hybrid electromagnetic actuator is determined based on the vibration criterion for vibration-sensitive equipment. In basic design stage of the electromagnetic actuator, the simple reluctance method is adapted to analyze magnetic circuits. The result is verified by finite element analysis using ANSYS Emag. Finally, some design parameters are optimized under several constraint conditions. Through this study, the design procedure for a specific electromagnetic actuator is set up using a simple reluctance method.

Almost all buildings/infrastructures made of composite materials are fabricated without proper design. Unlike airplane or automobile parts, prototype test is impossible. One cannot destroy 10 story buildings or 100-meter long bridges. People try to build 100-story buildings or several thousand meter long bridges. In order to realize "composites in construction", the following subjects must be studied in detail, for his design: Concept optimization, Simple method of analysis, Folded plate theory, Size effects in failure, and Critical frequency. Unlike the design procedure with conventional materials, his design should include material design, selection of manufacturing methods, and quality control methods, in addition to the fabrication method.on method.

This paper describes the optimum design for journal bearing by using simulated annealing method. Simulated annealing algorithm is an optimum design method to calculate global and local optimum solution. Dynamic characteristics of a journal bearing are calculated by using finite difference method (FDM), and these values are used for the procedure of journal bearing optimization. The objective is to minimize the resonance response (Q factor) of the simple rotor system. Bearing clearance and length to diameter ratio are used as the design variables.

In order to set up the design rule of micro optical bench, optical coupling efficiencies of two sets of test benches are calculated. Simple linear connections of incoming and outgoing optical fibers with and without ball lenses are designed. Positional errors that are possible in actual fabrication processes are considered in the calculations and their tolerances are determined from 3dB conditions. For a simple fiber-to-fiber connection, the working distance is limited to $2.7\mu\textrm{m}$ and tilt error $5.8^{\circ}$. When ball lenses are located in front of each fiber, the working distance can be extended over $60\mu\textrm{m}$ , but the positional errors have the strong interaction among position parameters and thus should be considered simultaneously for tolerance design.
