The purpose of study was to determine the organoleptic characteristics of homemade basil-pasta made in various compounding ratio according to central composite design. The optimum mixing condition for basil-pasta was optimized by response surface methodology. The texture, including color, flavor, elasticity and overall quality, was measured as sensory evaluation. The optimum mixing rates of durum wheat semolina, basil and egg were 73.97g, 5.95g and 36.17g for color, 53.14g, 4.52g and 35.85g for flavor, 48.75g, 2.95g and 36.85g for elasticity. The organoleptic overall quality of basil-pasta showed the maximum score in the mixing condition of 55.52 g durum wheat semolina, 4.55g basil paste and 35.51g egg.

Entering into the 21st century, digital culture and the innovation of media technology have drastically changed our understanding of the concept of space. Increased availability of information made possible by technological advancement has, directly or indirectly, contributed to the development of space design, which, in turn, offers a possibility for a new paradigm in space design. Given these fundamental changes, this study seeks to explore how to understand the expansion of the concept of space. In order to answer this question, this study investigates de-materialization tendency in modern architectural design such as transparency, anti-gravity, complexity and simultaneity of space. It examines the interaction-oriented nature of space among human, information and time. Finally, based on concepts such as new hyper-surface, which transcend the limitations of space and time, it explores new emerging trends in space design.

To determine the optimum mixing conditions of nopal jelly, samples were prepared with various compounding ratios of gelatin(16, 18, 20, 22 and 24g), sucrose(100, 120, 140, 160 and 180g), Citric acid(2, 3, 4, 5 and 6) using a central composite design. Physical and sensory evaluations were performed and considered using a response surface methodology. The optimum mixing rates which meet sensory items is gelatin 20.19g, sucrose 141.52g and citric acid 4.04g.

The commercialization of the fifth generation (5G) mobile systems has quested enabling technologies, such as intelligent reflecting surface (IRS) transmissions, towards the sixth generation (6G) networks. In this paper, we present a bit-error rate (BER) performance analysis on IRS transmissions in 5G non-orthogonal multiple access (NOMA) networks. First, we derive a closed-form expression for the BER of IRS-NOMA transmissions under Rician fading channels. Then, by Monte Carlo simulations, we validate the proposed approximate BER expression, and show numerically that the derived BER expression is in good agreement with Monte Carlo simulations. Furthermore, we also analyze the BER performance of IRS-NOMA networks under Rician fading channels with different numbers of reflecting elements, and demonstrate that the performances improve monotonically as the number of reflecting devices increases.

The efficiencies of rates and energy in the fifth generation (5G) wireless channels can be improved via intelligent reflecting surface (IRS) transmissions, towards the sixth generation (6G) mobile communications. While previous works have considered mainly optimizations of IRS transmissions, we propose a performance analysis on the total power in terms of the number of reflecting devices for IRS transmissions in non-orthogonal multiple access (NOMA) networks. First, we derive an analytical expression of the total power gain factor in terms of the number of reflecting devices for the cell-edge user in IRS-NOMA systems. Then we evaluate how many reflecting devices we need to obtain a total power gain in dB. Moreover, we also demonstrate numerically the signal-to-noise ratio (SNR) gain of the IRS-NOMA system over the conventional NOMA system based on the achievable data rate.

The purpose of this study was to determine the optimum amount of four ingredients (spirulina, sugar, lemon and orange) for the preparation of spirulina madeleine using response surface methodology. Spirulina was added at a level of 3.5-6.0 g, sugar powder, at 40-60 g, while lemon and orange peel were included at a level of 0-8 g. The optimum mixing rates of spirulina powder, sugar powder, lemon and orange were 3.5, 40, 0, and 8 g for overall quality and 3.52, 54.42, 0, and 8 g for maximum score of overall organoleptic quality, respectively.

This study was to provide the fundamental data for the ease necessary to design clothes by investigating the variation of the upper body surface with the method of surgical tape. The subject were 8 young women in the standard somatotype. In the form of body surface according to arm movements, the shape of armscye circumference became gentle from the sunken form for the standing posture; scye depth became lower; lateral shoulder moved and rose toward the front center as the angle of arm movement became larger; scye depth is greatest in the standing. The items of horizontal ware largest in the standing posture except for front neck base circumference and front interscye breadth for side $90^{\circ}$ movement. In the items of vertical, while most of the front items increased but back ones generally decreased for all movement compared to the standing. After comparing differences in actual values between the form of body surface in the standing posture and the direct measurement, the following ease were suggested considering minimum measures to accommodate daily movements. Bust circumference/2 = 3cm; waist circumference/2 = 1.5cm; front interscye breadth/2 = 0.6cm; back interscye breadth/2 = 0.6cm; and underarm depth = 1.5cm

The purpose of this study is to seek the change of body surface according to cycling motions and to give suggestions to the pattern and spare space between body and wear in each bodily parts to be heavily considered for making the bicycle wear. The cycling motions were analyzed by taking the sequential pictures of cycling covering motion by a digital camera. The experiments with gypsum were toward a woman in her twenties. We draw the line standard of the body's surface, separated their gypsum-replicated fragments of body's surface following the analyses of the change in their lengths. As the motions were made, we decided the degree of the changed length as spare space when compared the erected posture with the cycling posture, presenting the pattern of the cycling wear with the preparation of wears for testing. After that, the essential experiments were conducted toward three cycle players wore our experimental wears. Regards their evaluated appearance, evaluations over three points were obtained from all parameters except the width of front armhole. Accordingly, our experimental wears were remarkably understood as a relatively proper wear as bicycle wear.

The purpose of this study was to develop the beautiful basic bodice pattern that satisfied both functionality and aesthetics on the basis of the change in the figure and length of surface body for each movement through a three-dimensional development figure of surface body for young women (aged between 18 and 24) who were very sensitive to fitness of clothes. Existing three basic bodice patterns (Yim wonja-, ESMOD-, and FIT-types) were selected and then compared and analyzed in terms of drawing methods and the wearing test was carried out by a sensory test in order to design an experimental prototype. The design of study prototype was improved by three wearing test that was correlated with low satisfactory item. And the ease was established by difference of previous direct measurement and body surface measurement.

In the apparel industry, the technology has been advanced rapidly. The use of 3D scanning systems fur the capture and measurement of human body is becoming common place. Three dimensional digital image can be used for design, inspection, reproduction of physical objects. The purpose of this study is to develop a method that drafts men's basic bodice pattern from scanned 3D body surface shape data. In order to pursue this purpose the researchers developed pattern drafting algorithm. The 3D scanner used in this study was Cyberware Whole Body Scanner WB-4. The bodice pattern drafting algorithm from 3D body surface shape data developed in this study is as follows. First, convert geometric 3D body surface data to 3D polygonal mesh data. Second, develop algorithm to lay out 3D polygonal patches onto a plane using Auto Lisp program. The polygon meshes are coplanar, and the individual mesh is continuously in contact with next one The bodice front surface shape data in polygonal patches form was lined up in bust and waist levels. The back bodice was drafted by lining up the polygonal mesh in scapula, chest, and waist levels. in the drafts, gaps between polygons were formed into the darts.
