The Solar Daylighting Technology is considered with the plan that will be able to embody the energy technology which is possible to continue. Daylighting has an considerable advantage of the high effectiveness and the various use because daylighting can use the infrared ray, the visible ray and the ultraviolet rays without energy transformation. In this study, the experiment is tried of making the shape and an arrangement of the reflector different After establishing the reflector in the height(10m) which is fixed. It's also researched on the shape of the efficient reflector using the program(Trace Pro) at the time of the autumnal equinox and the winter solstice at fixed hours.

Process mining aims at mining valuable information from process execution results (called "event logs"). Even though process mining techniques have proven to be a valuable tool, the mining results from real process logs are usually too complex to interpret. The main cause that leads to complex models is the diversity of process logs. To address this issue, this paper proposes a trace clustering approach that splits a process log into homogeneous subsets and applies existing process mining techniques to each subset. Based on log profiles from a process log, the approach uses existing clustering techniques to derive clusters. Our approach are implemented in ProM framework. To illustrate this, a real-life case study is also presented.

Objective: A trial was conducted to investigate the effects of supplemental levels of Mn provided by organic and inorganic trace mineral supplements on growth, tissue mineralization, mineral balance, and antioxidant status of growing broiler chicks. Methods: A total of 500 male chicks (8-d-old) were used in 10-day feeding trial, with 10 treatments and 10 replicates of 5 chicks per treatment. A 2×5 factorial design was used where supplemental Mn levels (0, 25, 50, 75, and 100 mg Mn/kg diet) were provided as MnSO₄·H₂O or MnPro. When Mn was supplied as MnPro, supplements of zinc, copper, iron, and selenium were supplied as organic minerals, whereas in MnSO₄·H₂O supplemented diets, inorganic salts were used as sources of other trace minerals. Performance data were fitted to a linearbroken line regression model to estimate the optimal supplemental Mn levels. Results: Manganese supplementation improved body weight, average daily gain (ADG) and feed conversion ratio (FCR) compared with chicks fed diets not supplemented with Mn. Manganese in liver, breast muscle, and tibia were greatest at 50, 75, and 100 mg supplemental Mn/kg diet, respectively. Higher activities of glutathione peroxidase and superoxide dismutase (total-SOD) were found in both liver and breast muscle of chicks fed diets supplemented with inorganic minerals. In chicks fed MnSO₄·H₂O, ADG, FCR, Mn balance, and concentration in liver were optimized at 59.8, 74.3, 20.6, and 43.1 mg supplemental Mn/kg diet, respectively. In MnPro fed chicks, ADG, FCR, Mn balance, and concentration in liver and breast were optimized at 20.6, 38.0, 16.6, 33.5, and 62.3 mg supplemental Mn/kg, respectively. Conclusion: Lower levels of organic Mn were required by growing chicks for performance optimization compared to inorganic Mn. Based on the FCR, the ideal supplemental levels of organic and inorganic Mn in chick feeds were 38.0 and 74.3 mg Mn/kg diet, respectively.

불연속면의 기하학적 특성 조사는 일반적으로 조사자가 암반 노출면에서 직접 측정 작업을 수행하여 자료를 획득한다. 이러한 방법은 조사 범위에 대한 제약이 있을 수 있고, 자료의 획득과 처리에 많은 비용과 시간을 소요하게 되는 단점이 있다. 이를 극복하기 위하여 디지털 영상 분석은 현장 측정에 대한 대안적인 방법으로 제시될 수 있으며, 자동화된 측정과 분석을 제공한다는 장점이 있다. 본 연구는 디지털 사진기에 의해 촬영된 암반 노출면 영상으로부터 절리의 궤적을 인식하기 위한 목적으로 수행되었으며. 결과적으로 부존하는 절리맵을 자동화된 방법으로 작성하고자 하였다. 이를 위하여 개발된 해석 과정은 Media cybernetic사의 ImagePro Plus ver 4.1의 매크로 명령을 사용하여 프로그램으로 작성하였다. 본 연구에서 수행된 영상처리 과정은 영상처리, 절리 인식, 절리 궤적 추적 단계로 구분된다. 영상 처리 단계는 암반 사면 영상에 나타나는 노이즈를 제거하거나 완화시키기 위한 단계로서 영상 필터들을 조합하여 적용하였다. 절리 인식단계는 암반과 절리의 명도차에 의한 국부적인 절리 궤적을 인식하는 과정이다, 인식된 절리는 절리 궤적 추적 단계에서 수치적 의사 결정이 가능한 구조로 재구성된 후 서로 연결되어 절리맵으로 완성된다. 암반 사면의 원 영상과 이러한 영상 처리 알고리즘에 의한 일련의 과정을 거쳐 작성된 절리맵을 비교한 결과, 75～80% 정도의 불연속면들이 인식된 것으로 나타났다. 본 연구와 관련하여 앞으로는 절리 궤적 추적에 더욱 적합한 영상을 획득하기 위한 영상 필터의 조합부분과 절리 궤적의 연결과정에서 seed pixel을 자동적으로 선택할 수 있는 부분을 보다 집중적으로 연구할 필요가 있을 것으로 생각한다.

The previous studies on the intake of trace elements performed in Korea were only concerned about major elements like Fe, Zn or Cu. There is little data about the intake of minor elements like Mn, Se, Mo or Cr. And most of the data were obtained by calculation using Food Composition Tables or by analysis using atomic absorption spectrophotometers (AAS). The purpose of this study, therefore, was to evaluate the dietary intake of seven trace elements, Fe, Zn, Cu, Mn, Se, Mo, and Cr of Korean adult wonmen and to compare the data between analyzed using ICP-MS (or ICP-AES) and calculated by the CAN-Pro (or Food Composition Table). A total of nineteen adult women participated voluntarily in this study and collected one-tenth of the foods that they consumed for three consecutive days. Analyzed intake of Fe of the subjects was $6.94{\pm}2.18$ (calculated, $18.87{\pm}4.50$) mg/day, that of Ze was $9.35{\pm}4.95$ (calculated, $8.35{\pm}2.87mg/day$), that of Cu was $1.18{\pm}0.26\;(1.11{\pm}0.32mg/day)$, that of Mn was $3.69{\pm}0.69\;(2.83{\pm}1.68mg/day)$, that of Se was $41.93{\pm}9.28$ (calculated, $27.58{\pm}6.97{\mu}g/day$), that of Mo was $134.0{\pm}49.1{\mu}g/day$, and that of Cr was $136.5{\pm}147.9{\mu}g/day$. The analyzed Fe intake of the subjects did not meet Estimated Average Requirement (EAR) nor Recommended Intakes (RI) for Korean women aged 20-29 years old. However, the analyzed intakes of the other six elements, Zn, Cu, Mn, Se, Mo, and Cr, seemed to meet each of the respective RIs. The analyzed Fe intake was significantly lower than the calculated one, in fact by 2.72 times, however, the analyzed intakes of the other elements, Mn and Se, were significantly higher and those of Zn and Cu were similar than each of the calculated ones. The difference of the data between analyzed and calculated intakes indicates that it is necessary to set up database on trace element contents of foods of the Food Composition Table and the CAN-Pro so as to have accuracy.

Pattern recognition receptors are known to participate in the activation of Prophenoloxidase system. In this study, a 1,3-${\beta}$-D-glucan recognition protein was detected for the first time in Antheraea pernyi larvae (Ap-${\beta}GRP$). Ap-${\beta}GRP$ was purified to 99.9% homogeneity from the hemolymph using traditional chromatographic methods. Ap-${\beta}GRP$ specifically bind 1,3-${\beta}$-D-glucan and yeast, but not E. coli or M. luteus. The 1,3-${\beta}$-D-glucan dependent phenoloxidase (PO) activity of the hemolymph inhibited by anti-Ap-${\beta}GRP$ antibody could be recovered by addition of purified Ap-${\beta}GRP$. These results demonstrate that Ap-${\beta}GRP$ acts as a biosensor of 1,3-${\beta}$-Dglucan to trigger the Prophenoloxidase system. A trace mount of 1,3-${\beta}$-D-glucan or Ap-${\beta}GRP$ alone was unable to trigger the proPO system, but they both did. Ap-${\beta}GRP$ was specifically degraded following the activation of proPO with 1,3-${\beta}$-Dglucan. These results indicate the variation in the amount of Ap-${\beta}GRP$ after specific immune challenge in A. pernyi hemolymph is an important regulation mechanism to immune response.

This study looks at optimizinge light redistribution to improve the overall illuminance uniformity of commercial IRED modules. To obtain uniform illumination over a prescribed rectangular area, a freeform surface lens was evaluated using TracePro. The LED light overall illuminance uniformity regulated in KSC 7658 was verified using Relux software. Experimental test results showed 0.81 overall illuminance uniformity for rectangular light distribution of LED lights having a radiation angle of $80^{\circ}$. After fabricating prototype IRED lights based on these simulation results, illuminance performance was observed when used as actual IRED lighting with a nighttime CCTV system. Image observation photographs of the prototype $80^{\circ}$ rectangular IRED lights confirmed that object images can be seen clearly owing to high overall illuminance uniformity, and that dark regions of the CCTV screen were not shown.

최근 네트워크 및 통신 기술의 발달로 4세대 무선이동통신은 사용자가 급격하게 늘어나고 있다. 하지만 이와 동시에 통신 데이터 및 프라이버시에 대한 외부 공격 또한 증가하고 있는 실정이다. 따라서 안전한 통신에 대한 고려는 성공적인 4세대 이동통신을 위해서 매우 중요한 사항이라고 할 수 있다. 본 논문에서는 4세대 LTE 이동통신 환경에서 통신 기기의 위치 정보를 탐지함으로써 사용자의 위치 프라이버시를 침해하는 공격모델을 제시한다. 그리고 이를 해결하기 위한 개선된 LTE 프로토콜을 제시한다. 제안하는 기법은 연산량이 적은 대칭키 암호화 알고리즘을 이용함으로써 위치정보에 대한 구별가능성을 제거함으로써 프로토콜의 효율성과 안전성을 보장할 수 있다. 또한 위치 프라이버시 보호 측면에서 제안기법의 안전성은 ProVerif 툴을 이용하여 검증하였다.
