현재 사용되고 있는 생체용 금속재료로 스테인레스강(SUS 316), Co-Cr강, 순수 Ti, Ti-6Al-4V이 많이 사용되고 있으며 그 중에서도 특히 Ti이 각광을 받고 있다. 그러나 순수한 Ti은 생체적합성과 내식성은 좋은 반면 기계적 성질이 합금에 비해 뒤떨어지고, Ti-6Al-4V은 V의 세포독성이 지적되고 있어 이러한 문제를 해결하기 위해 세포독성이 없는 함금원소를 Ti에 첨가한 새로운 합금을 설계하였다. 그 중에서 Ti-20Zr-3Nb-3Ta-0.2Pd-1In과 Ti-5AI-4Zr-2.5Mo은 기계적 성질도 뛰어나고 우수한 전기화학적 부식특성을 가지고 있었다.

In this study, one of the measures for the promotion of the growth of trees planted in poor drainage areas, which functionality pipe supplying oxygen in the soil, and promotes drainage, barren soil and poor drainage areas in planting design was to provide the basic data to compare the impact on the application of functionality pipe. The Zelkova serrata testing materials were selected, planted a total of 12 by three to four individual experiments were conducted. Growth measurements of the items Plot A > Plot C > Plot D > Plot B were excellent in the order of height, number of leaves, leaf width, and chlorophyll content, Plot A > Plot C > Plot D > Plot B was in good order of the growth of the length of the root-collar diameter, Plot C > Plot A > Plot B > Plot D in order rate of variation was good. This has adverse effects on plant growth, poor drainage planting base represents, promote drainage and oxygen supply technique can be applied good to the planting from Zelkova serrata growth based drainage is poor and barren presented as part of research to be done in the future include a means for promoting the growth of plants in soil, the planting design.

Buffalo meat patties with two fat levels, F1 (15% added fat) and F2 (5% added fat and 3% tapioca starch), were cooked in a pre-heated hot air oven (HO) at $175{\pm}2^{\circ}C$ for 15 min, in a microwave oven (MO) for 70 sec and by pressure cooking (PC) at 15 psi pressure for 10 min. and compared for physico-chemical, processing, sensory and microbiological quality attributes. F2 had significantly (p<0.05) higher value for the moisture and moisture protein ratio than F1. However, MO and PC patties had significantly (p<0.05) higher moisture content than HO-cooked buffalo meat patties irrespective of fat content. Highest fat percentage was in MO patties while the minimum was in PC patties. Moisture and fat retention and cooking yield were highest in MO patties irrespective of added fat content in the formulation. Cooking yield and dimensional parameters were better maintained in F2 than F1. Sensory scores viz. appearance and color, flavour, juiciness and texture for HO patties were better than other cooking methods. Sensory panelists rated overall acceptability of HO patties very good to excellent, whereas PC and MO patties were rated as good to very good irrespective of fat content. Microbiological quality was comparable in both groups irrespective of cooking methods used.

The purpose of this study is to identify the effects of sportswear brands' country-of-origin on purchase intention (PI) in terms of brand personality as perceived by Chinese university students. Chinese students preferred to shop for sportswear at specialty stores, liked Nike and Adidas most, design was the most important factor when selecting, selected their sportswear themselves, and gathered information from TV ads. With regard to perceptions of brands country-of-origin, America was perceived as a developed country, influential to the world, but as having a bad relationship with China. Germany was perceived as a developed country and as having a well-developed civic culture, good people image, high technology, high influence on the world, and a good relationship with China. Italy was perceived as a developed country with the highest civic culture. China was perceived as a developing country, as having a good people image, and low technology and low influence on the world. Japan was perceived as a developed country with high technology. Factors of brand personality were sincerity, competence & sophistication, and excitement. Nike was perceived as having high competence & sophistication and excitement, Adidas as having high competence & sophistication and excitement, Lining as having high sincerity, and Mizuno's brand personality was very low. People image, competence & sophistication and excitement became higher, PI of Adidas increased. If people image, competence & sophistication and excitement became higher, PI of Kappa increased. If a country was developed and competence & sophistication and excitement became higher, PI of Lining increased. If civic culture, people image, technology, competence & sophistication and excitement became higher, PI of Mizuno increased.

The optimal conditions for mycelial growth of P. linteus ASI 26011 were 25-30$^{\circ}C$ and pH 6.0, respectively. The mycelial growth of P. linteus was excellent on MCM medium. In case of carbon sources, the mycelial growth of P. linteus was best on the culture media that were contained with sucrose, mannose and glucose. Potassium nitrate and sodium nitrate were good for the mycelial growth of P. linteus as a nitrogen source. For comparison of the mycelial colonization of P. linteus on logs, several techniques of inoculation were tested; the sterilized short log inoculation, drilling inoculation and log-end sandwich inoculation. The mycelial colonization of P. linteus on logs was good in the treatment of sterilized short log inoculation, but poor in the traditional methods such as drilling inoculation and log-end sandwich. The initial mycelial growth and the full mycelial colonization of P. linteus were the best on 20 cm logs under the condition of 42% of moisture content in log. Also the initial mycelial growth of P. linteus was accelerated over 12 hours of sterilization. Burying method of logs after 5-6 months of incubation was the best for formation of basidiocarp of P. linteus. The formation of fruiting body of P. linteus was quite good in the cultivation house at the 31-35$^{\circ}C$ and over 96% of relative humidity.

Substitution of natural fine aggregates with industrial by-products like precious slag balls (PS Balls) offers various advantages like technical, economic and environmental which are very important in the present era of sustainability in construction industry. PS balls are manufactured by subjecting steel slag to slag atomizing Technology (SAT) which imparts them the desirable characteristics of fine aggregates. The main objective of this research paper is to assess the feasibility of producing good quality concrete by using PS balls, to identify the potential benefits by their incorporation and to provide solution for increasing their utilization in concrete applications. The study investigates the effect of PS balls as partial replacement of fine aggregates in various percentages (20%, 40%, 60%, 80% and 100%) on mechanical properties of concrete such as compressive strength, splitting tensile strength, and flexural strength. The optimum mix was found to be at 40% replacement of PS balls with maximum strength of 62.89 MPa at 28 days curing. Permeability of concrete was performed and it resulted in a more durable concrete with replacement of PS balls at 40% and 100% as fine aggregates. These two specific values were considered as optimum replacement is 40% and also the maximum possible replacement is 100%. Scanning electron microscope (SEM) analysis was done and it was found that the PS balls in concrete were unaffected and with optimum percentage of PS balls as fine aggregates in concrete resulted in good strength and less cracks. Hence, it is possible to produce good workable concrete with low water to cement ratio and higher strength concrete by incorporating PS balls.

컴퓨터 기술이 발달하면서 악보 편집 작업을 할 수 있는 사보 프로그램도 많이 발전했다. 음표, 코드, 악보 기호 등을 편리하게 넣을 수 있을 뿐만 아니라 미리 들어볼 수 있는 재생기능도 제공하여 현재 만들고 있는 악보를 연주하면 어떤 음악이 나올지 알 수 있다. 현재 상용화 되어 있는 사보 프로그램들은 악보를 보기 좋게 만들어주고 음표 재생도 VSTi(Virtual Studio Technology instrument)를 이용하여 잘 해주지만, 코드(Chord) 반주 기능은 상대적으로 취약하여 표기한 코드가 맞는지 알아보는 것이 힘들다. 따라서 음악 코드를 적절하게 반주해줄 수 있으면 멜로디와 코드 중심으로 이루어진 밴드 음악 악보를 만드는데 좋은 참고가 될 수 있다. 본 연구에서는 기존 사보 프로그램의 코드재생 기능을 강화하기 위하여 피아노 코드 톤을 적절히 선택하는 알고리즘을 제시하고 프로그램으로 구현하였다. 이를 활용하면 코드 연주 기능이 강화되어 밴드 음악 악보를 만드는 악보 편집자들이 더 편하게 악보를 제작할 수 있다.

The good features of the analytic function expansion nodal (AFEN) method are utilized to develop a practical scheme jot the multigroup diffusion problems, in combination with the polynomial expansion nodal (PEN) method. The thermal group fluxes exhibiting strong gradients are solved by the AFEN method[1-6], while the fast group fluxes that are smoother than the thermal group fuzes are solved by the PEN method[7-9]. The scheme is applied to a MOX-fuel loaded core with good results.
