본 논문은 몸체 3D 스캔과 모션 캡처 장비를 활용한 3D 애니메이션 형태의 바디 프로필을 제안한다. 사용자는 미리 정해진 몇 개의 포즈에 대하여 3D 스캔을 수행함으로써 애니메이션 형태를 가진 자신만의 바디 프로필을 제작할 수 있다. 이를 위하여 일련의 포즈를 수행하는 템플릿 애니메이션을 모션 캡처를 통하여 획득하였고, 사용자로부터 획득된 3D 스캔 데이터를 애니메이션의 각 정점 포즈에 포즈 공간 디포머(Pose-space deformer)를 통하여 매핑시켰다. 이를 통하여 만들어진 3D 애니메이션 형태의 바디 프로필은 기존의 정적인 2D 이미지나 3D 스캔데이터보다 사용자에게 더 큰 만족도를 줄 수 있음을 확인할 수 있다.

Objective: The experiments were carried out to measure the effect of multivitamin, acidifier and Azolla on growth performance, profitability and lipid profiles of blood of broiler chickens to produce safe and cost effective broilers. Methods: In experiment 1, 240 day-old Cobb-500 broiler chicks were fed diets; $D_1$ (control), $D_2$ ($D_1$ with 1 mL multivitamin/liter water), $D_3$ ($D_1$ with 1 mL acidifier/liter water), $D_4$ ($D_1$ with 1 mL multivitamin and 2 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication. In experiment 2, 150 day-old Cobb-500 broiler chicks were fed diets; $T_1$ (control), $T_2$ (5% Azolla in the diet), $T_3$ (7% Azolla in the diet) and $T_4$ ($T_1$ with 1 mL multivitamin and 1 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication in control, and 10 chicks/replication in the remaining dietary treatment groups for 35 days. Results: In experiment 1, the highest live weight was observed in $D_4$ (p<0.05), however, feed intake was statistically similar between diets (p>0.05). The lowest feed conversion ratio (FCR) (p<0.001) and mortality (p<0.05) were observed in $D_2$ followed by $D_4$, $D_1$, and $D_3$, respectively. There were no significant differences between diets for feed cost and net profit (p>0.05). However, evidently but not significantly, the highest net profit was obtained in $D_2$ followed by $D_4$, $D_1$, and $D_3$, respectively. In experiment 2, the highest live weight (p<0.05) and feed intake (p<0.001) were observed in $T_4$. Mortality (p<0.01), FCR (p<0.01), feed cost (p<0.05) and net profit (p<0.05) were significantly different among diets. Considering net profit, $T_2$ was the best performing dietary group followed by $T_3$, $T_1$, and $T_4$, respectively. The lowest lipid profiles were observed in $D_3$ followed by $D_1$, $D_4$, and $D_2$, respectively (p<0.05). In experiment 2, the lowest total cholesterol, TG, and the highest amount of high density lipoprotein were observed in $T_2$, followed by $T_3$, $T_1$, and $T_4$, respectively (p<0.05). Evidently but not significantly, low density lipoprotein was the highest in $T_2$ followed by $T_3$, $T_4$, and $T_1$, respectively (p>0.05). Conclusion: In conclusion, Azolla and acidifier reduced lipid profiles of broiler chickens. Considering net profit and lipid profiles, 5% Azolla may be the suitable dietary group for producing safe and profitable broilers. However, more studies are needed to confirm this study prior to suggesting using Azolla in the poultry industry.

A method for generating 3D solid models and drawings for a rotor in the steam turbine is proposed. One of the most important design steps is generating the drawing for manufacturing it. This step is a very routine and time-consuming job because each drawing is composed of several kinds of views and many dimensions. To achieve automation for this activity, rotor profiles are composed of 2D entity groups with attributes. Based on this, the improved design process is developed as follows. First, the rotor profiles can be selected by searching for 2D entity groups using the related attributes. Second, the profiles are connected sequentially so that an entire rotor profile is determined. The completed profile is used to generate 2D drawings automatically, especially views, dimensions, and 3D models. The proposed method is implemented using a commercial CAD/CAM system, Unigraphics, and API functions written in C-language and applied to the rotor of steam turbines. Some illustrative examples are provided to show the effectiveness of the proposed method.

In our paper is reported a new 3D(dimensional) trajectory split approach with greatly improved efficiency for the Monte Carlo simulation of the 3D profiles of implanted ionand point defect concentrations in single-crystal silicon. This approach has been successfully implemented in our TRICSI Monte Carlo code. Combined with the previously developed model for damage accumalation in our TRICSI code, this model allows phasically based dynamic simulation of 3D profiles over an subsequent process simulation such as diffusion modeling and simulation. A typical time saving of over 10 timeshas been achieved for 3D simulation. Our method ensures much better region aground the implanted area. For 1-D simulation, the optimized condition for trajectory split has set to 3,000 pseudoparticles with 2 split branches.

Detailed comparison of low-voltage scanning electron microscopy and electron holography techniques for two-dimensional (2D) dopant profiling was carried out with using the same multilayered p-n junction specimen. The dopant profiles obtained from two methods are in good agreement with each other. It demonstrates that reliability of dopant profile measurement can be increased through precise comparison of 2D profiles obtained from various microscopic techniques.

Electrophoretic resolution of superoxide dismutase (SOD) from the highly UV-resistant bacteria, Deinococcus species revealed multiple forms of superoxide dismutases (SODs) in D. radiodurans, D. grandis, and D. proteolyticus, as judged from electrophoretic properties and metal cofactors. A single SOD occurred in both D. radiophilus and D. radiopugnans. Deinococcal SODs were either MnSOD, FeSOD or cambialistic Mn/FeSOD. The unique SOD profile of each mesophilic Deinococcus species, multiplicity and metal cofactors would be valuable in identifying Deinococcus species.

This stud demonstrates the profiles of heavy ions (As, Sb) in silicon by high energy (1~10 MeV) implantation. Implanted profiles were measured by SIMS (Cameca 4f) and compared with simulation results (TRIM) program and analytical description method using Pearson function). The experimental results have a little bit deviation with simulation data in the case of As high energy implatation. But in the case of Sb, the experimental results are in good agreement with TRIM data. SIMS profiles are perfectly fitted with a analytical description method only using one pearson function in Sb implantation. but in the case of As, fitted profilesshow with a little bit deviations by channeling effects of SIMS profiles. Thermal annealing for electrical activation of implanted ions was carried out by furnace annealing and RTA(Rapid Thermal Annealing). Concentration-depth profile after heat treatement were measured by SR(Spreading Resistance) method.

In order to investigate the impact behaviors of 3-D braided glass/epoxy composites, the energy profiles and damage area were compared to the laminates of similar volume fraction and composition. The energy profiles showed different characteristics from each other which indicates they have distict energy absorption mechanisms. The image analysis on the damage projections visualized the crack propagation paths along the fiber direction.

This study was conducted to examine the correlation among meals variety, obesity index, blood pressure, and lipid profiles of Korean adults. A total of 308 adults(men 124, women 184) measured the anthropometric characteristics, blood pressure, dietary intake using 24-hour recall method, and serum lipid profile. The average ages of the study subjects were 50.9 yrs in men and 51.4 yrs in women. The average height, weight and BMI were 166.3 cm, 68.4 kg, $24.7\;kg/cm^2$ in men and 154.3 cm, 59.8 kg, $25.0\;kg/cm^2$ in women, respectively. The numbers of food items in meal of men and women were 14.1, 15.9 for breakfast, 15.7, 15.9 for lunch, 14.7, 14.1 for dinner, respectively. The numbers of dish items in meal of men and women were 4.0, 4.3 for breakfast, 4.3, 4.3 for lunch, 4.2, 3.9 for dinner, respectively. The average blood pressure, total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol and atherogenic index were 126.6/76.0 mmHg, 181.0 mg/dL, 157.7 mg/dL, 40.9 mg/dL, 108.6 mg/dL, 3.5 in men and 123.2/73.6 mmHg, 185.0 mg/dL, 137.3 mg/dL, 44.8 mg/dL, 112.7 mg/dL, 3.2 in women, respectively. The total cholesterol was negatively correlated to the number of food item for lunch(p<0.05). Therefore, more systematic studies to investigate the meal variety roles of blood lipids in meals of adults were required.

웹상에 가상테마파크와 같은 가상공간을 구축하기 위한 도구들로는 2차원 파노라마 영상을 이용한 QuickTime VR이나 3차원 모델링에 기반 한 VRML 등이 이용되어 왔다. QuickTime VR은 영상의 왜곡현상과 오브젝트의 실감 있는 조작 및 네비게이션이 어렵다는 단점을 가지고 있으며 VRML의 경우는 다양한 3차원 요소들을 사용자에게 제공이 가능하나 뷰어 제공이 어려워 사용자 접근이 용이하지 않았다. 따라서 본 연구에서는 웹상에서 가상테마파크와 같은 콘텐츠에 X3D의 컴포넌트와 프로파일 개념을 도입하여 사용자 접근을 용이하게 하고 시장성을 확보하는 3차원 가상공간을 구축하고자 한다.
