  • This project was to compare the effects of consuming diets incorporating soybean oil , canola oil, ad palm oil on blood serum lipid patterns and fecal fat excretion in healthy human adults. The project was composed of three studies that were run concurrently . Each study was composed of a 4-day pre-trial period and two , 14-day experimental periods arranged according to a cross-over design. During the pre trial period, subjects were allowed to eat self-selected diets. During the experimental period , subjects were asked to eat constant, laboratory controlled diets in which sources of dietary fat varied . Thirty healthy , young adult subjects were fed a laboratory controlled diet incorporating soybean oil, canola oil, and palm oil. Test oils provided approximately 20% of the total dietary calories form all sources. Total dietary fat from all sources was approximately 30% of consumed calories. The highest serum total cholesterol , LDL cholesterol, VLDL cholesterol , and triglyceride values occurred when pam oil diets were eaten. However, feeding on palm oil diets resulted in the same HDL cholesterol content as with soybean oil or canola oil diets. Soybean oil diets produced numerically lower blood serum total cholesterol , LDL cholesterol, and triglycerides, and numerically higher HDL cholesterol and VLDL cholesterol than did those with canola oil. Fecal fat excretion was numerically lower with soybean oil diets than with canola diets. The highest fecal fat excretion occurred when palm oil diets were eaten.

  • This study investigates the merits of incorporating augmented reality in mobile games and proposes a mobile game application that combines augmented reality technology with gaming. The proposed study postulates that augmented reality technology can be employed for developing games on smartphones. The proposed application involves the implementation of a 3D virtual object in the real world by incorporating a target image. The proposed application also employs an intuitive interface with simplified manipulation based on touch, and allows players to collect and combine items for acquiring new items, thus making it elementary to pass the game stages. Furthermore, a ranking system has been introduced in the proposed application for enhancing the amusement factor of the game. The novelty of the proposed application lies in the fact that the virtual button function has been employed for combining physical and virtual objects while playing the game, without incorporating location-based services.

  • PURPOSES: The scaling of a concrete surface caused by the combined effects of frost and de-icing salts is one of the main reasons for the need to repair transportation infrastructures in cold-climate regions. This study describes the results of attempts to determine the scaling resistance of concrete incorporating mineral admixtures such as fly ash, GGBFS, and silica fume, and subjected to the actions of frost and salt. METHODS : Conventionally, to evaluate the fundamental properties of concrete, flexural and compressive strength measurements are regularly performed. Based on the ASTM C 672 standard, concrete is subjected to 2%, 4%, and 8% $CaCl_2$ salt solutions along with repeated sets of 50 freeze/thaw cycles, and the scaling resistance was evaluated based on the mass of the scale and a visual examination. RESULTS : It was observed that silica fume is very effective in enhancing the scaling resistance of concrete. Meanwhile, concrete incorporating GGBFS exhibited poor resistance to scaling, especially in the first ten freeze/thaw cycles. However, fly ash concrete generally exhibited the maximum amount of damage as a result of the frost-salt attack, regardless of the concentrations of the solutions. CONCLUSIONS: It can be concluded that the scaling resistance of concrete is highly dependent on the type of the mineral admixture used in the concrete. Therefore, to provide a durable concrete pavement for use in cold-climate regions, the selection of a suitable binder is essential.

  • In this study, as the resistance of the carbonation for high volume admixture incorporating concrete, coating effect of using refined cooking oil in the surface of high volume admixture incorporating concrete has been tested. The following results could be made as the conclusion. For the fresh concrete, the slump and air content has been identified as satisfying the target range. For the hardened concrete, comparing with specimen of Plain, specimen with coating showed better long age compressive strength. For the carbonation speed, the specimen of FA30 showed highest speed and the specimen of BS60 showed higher speed than specimen of Plain. For all the specimens coated with RCO, as the decrease of capillary pores inside the concrete, the carbonation speed has been obviously decreased and with even better effect than using PEP coating. It could be identified that specimens with coating by RCO showed good effect on refrain the speed of carbonation.

  • In this study, a mix design for self compacting concrete was based on Okamura's method and concrete incorporated just a ground granulated blast furnace slag. Replacement ratio of slag is in the range of $20-80\%$ of cement matrix by volume. For the optimal self compactability in mixture incorporating ground granulated blast furnace slag, the paste and mortar tests were first completed. Then the slump flow, elapsed time of 500mm slump flow, V funnel time and filling height by U type box were conducted in concrete. The volume of coarse aggregate in self compacting concrete was in the range of $50-60\%$ to the solid volume percentage of coarse aggregate. Finally, the compressive and splitting tensile strengths were determined in the hardened self compacting concrete incorporating ground granulated blast furnace slag. From the test results, it is desirable for self compacting concrete that the replacement of ground granulated blast furnace slag is in the range of $40-60\%$ of cement matrix by volume and the volume of coarse aggregate to the solid volume percentage of coarse aggregate with a limit of $55\%$.

  • 본 논문에서는 최소 분류 오차 기법 (Minimum Classification Error, MCE)에 기반한 감정 인식을 위한 알고리즘 멀티 모달(Multi-modal) 시스템을 기반으로 제안한다. 사람의 음성 신호로부터 추출한 특징벡터와 장착한 바디센서로부터 구한 피부의 전기반응도 (Galvanic Skin Response, GSR)를 기반으로 특징벡터를 구성하여 이를 Gaussian Mixture Model (GMM)으로 구성하고 이를 기반으로 구해지는 로그 기반의 우도 (Likelihood)를 사용한다. 특히, 변별적 가중치 학습을 사용하여 최적화된 가중치를 특징벡터에 인가하여 주요 감정을 식별하는 데 이용하여 성능향상을 도모한다. 실험결과 제안된 감정 인식이 기존의 방법보다 우수한 성능을 보인 것을 알 수 있었다.

  • This study investigates the engineering properties of concrete incorporating lime stone crushed fine aggregate(Ls), which has been abandoned about 20% of total production due to the low purity. Test results showed that increase of Ls had favorable fluidity and slightly decreased air content. Bleeding capacity of all specimens was not appeared as those were high strength mixture proportion, but the specimens using more Ls accelerated initial and final setting. For the mechanical properties, specimens incorporating higher ratio of Ls, overall, resulted in increase of compressive strength, and exhibited very small inclined tendency in a dynamic elasticity modulus test In addition, for the durability properties, specimens incorporating higher Ls dramatically decreased a drying shrinkage and showed similar tendency in a frost & thaw test, as well as showing no more change in an accelerated neutralization test from the beginning. In conclusion, as it was confirmed in the experimental test, the high strength concrete applying Ls did not showed any problems in the aspects of engineering properties and mostly exhibited even more excellent quality than the specimens using natural fine aggregate.

  • This study investigates engineering properties of concrete using recycled coarse aggregated manufactured by bar-crusher. Test showed that Bar-crusher(S) had more effective results at fresh state than cone-crusher(C) and impact-crusher(I). In case of specimens manufactured by S, increase of spindle velocity, incorporating ratio of recycled aggregate and maximum size of aggregate inclined fluidity. As for the hardened concrete, compressive strength of specimens by C or I exhibited lower value than that of S. In addition, specimens using recycled aggregate manufactured by 400rpm and 500rpm of spindle velocity showed less than 10% reduction rate of strength, which is not significant reducing value. It is found that 500rpm of the spindle velocity had the best strength performance, while 600rpm was the worst. Strength value of specimens decreased as incorporating ratio of recycled aggregate inclined, but the strength value of most specimens exhibited less than 10% of reducing rate, assuming favorable result, only at less than 25% incorporating ratio of recycled aggregate.
