Green Tea consists of 15-30% catechins (a type of polyphenol), which act as super antioxidants, inhibitory action against aging process. Antioxidants fight radical-free oxygen, an agent which can begin the process of cancer by damaging essential body chemicals and harming DNA. This study was peformed to develop the elderly diet using Green Tea as an inhibitory action against aging process. Nokchaborijook (Baley gruel added rice powder and Green Tea) was manufactured by various levels of Green Tea(1, 4, 7%) and the grinding period(15, 30, 45 sec). The optimum levels of added Green Tea and grinding periods on Nokchaborijook were determined with the results of sensory evaluation by response surface methodology and analysis of composition. The Anti-oxidant Vitamin A, C, E and Flavonoid were increased with increased levels of Green Tea and grinding periods be decreased. As the levels of Green Tea and grinding periods were increased, the green color and penetrated force became stronger. Among the sensory attributes, Bitterness, Green Tea Flavor and Hashness were greater depending on increasing Green Tea. Jujube flavor was greater relying on decreasing Green Tea. Greenness and spreadability of particles were increased as both the amounts of Green Tea and the grinding period were increased. This result was used to determine the optimum conditions of adding levels of Green Tea and grinding periods. The optimum conditions of Nokchaborijook was established as adding of 5.8% Green Tea grinded for 15 seconds.

반도체 산업의 wafer 가공공정에서 발생하는 폐수를 재활용하고자 한외여과 공정을 이용한 막분리 공정의 도입 가능성을 검토하였다. Pilot 규모의 장치에 분획분자량이 각각 10,000, 20.000, 30,000인 한외여과막 모듈을 이용하여 투과유속 및 제거율 등을 측정하였다. 투과수의 성상은 SDI15, 탁도, 전기전도도, 실리콘 농도분석을 통해 공정수로 재이용이 가능함을 확인할 수 있었다. 투과유속 저하를 막기 위한 역세척 방법으로는 압축공기와 물은 sweeping 하는 방법이 가장 효과적이었고, 이때 투과유속의 회복율이 높게 나타났다. 분획분자량 30,000인 한외여과막에서 가장 높은 투과유속을 나타내었다. 또한 폐수의 평균 실리콘 입자 평균 함량은 3.8-5.6mg/ℓ이고, 투과수의 실리콘 입자 함량은 0.2μg/ℓ이하로 나타나 제거율은약 96%이상으로 나타났다.

본 연구에서는 sol-gel법으로 제조된 PbTiO3 (PT) 단층박막내의 실시간 응력과 두께 수축거동, 그리고 다층박막의 미세경도를 온도의 함수로 측정하여 열처리에 따른 PT박막내의 물리화학적 변화를 설명하였다. 단층박막은 상온에서 220˚C까지 급격한 수축을 보였으며 총수축량의 83%가 이 온도구간에서 일어났다. as-spun된 박막 내에는 이미 75MPa의 인장응력이 존재하였으며 130˚C부터 뚜렷이 증가하여 250˚C에서 147MPa의 최대 인장응력을 나타냈다. 인장응력의 급격한 감소가 일어나는 370˚C부터는 본격적으로 치밀화된 PT박막과 Si 기판과의 열팽창계수 차이가 주로 박막내의 응력을 결정하며, 이것은 다층박막의 미세경도가 300˚C 이후에서 급격히 증가하는 사실로도 뒷받침된다. 한편 다층박막에서 단층박막과 달리 550˚C까지 열처리후 Perovskite 상이 많이 생성되었으며 이는 박막 두께의 증가에 따른 homogenous 핵생성 site의 증가 때문이라고 생각된다

The powder forging process is an attractive manufacturing route for bevel gears. It offers beneficial material utilization and the minimization of finishing operations over that of conventional hot forging. The paper describes the process conditions for the powder forging of bevel gear, for example, powder alloy design, preform design, deformation of sintered preform, forging processes. The characteristics of prototype gear are investigated with microstructure, the density distribution, surface roughness of tooth, bending strength test of tooth, etc. The results of the bending strength test may prove the mechanical properties of powder forged gear.

This study is on the early historical background and the process of development of modern architecture in Thai, during the period from 1782(King Rama 1) to 1934(King Rama 7). Thai started tn form a connection with western nations from the late 18C, founded the Bangkok Dynasty. Since then, Thai was increasingly influenced by western civilization and this trend included an increasing influence of western architecture. In this paper, the centeral objective is to observe the architectural change during the period from King Rama 1(1782-1809) to King Rama 7(1925-1934). This can be divided into three period. During the first period, from King Rama 1 to King Rama 3(1824-1851), Thai architecture showed a tendency to follow the preceding traditional example and to imitate Chinese architecture. The second period is from King Rama 4(1851-1868) to King Rama 5(1868-1910). During this period, Thai architectural design was increasingly influenced by western concepts, specially European Neo-classicism Style. During the third period, from King Rama 6(1910-1925) to King Rama 7(1925-1934), Thu had been enjoying extensive commerce with western nations. The great developments in the field of architecture during this reign were apparent in the construction of public utilities and facilities. These buildings were designed by western architects. At this time, modern architectural concept of western was introduced.

This study was conducted to develop a new RBC process available for the effective removal of organic matters and nitrogen in sewage. The RBC process for the oxidation organic compounds and nitrification was designed to occur at the 1st-stage and next-stage RBC respectively. Then nitrified water was recycled to the denitrifying RBC located at the lower part of the 1st-stage RBC. Some results were summarized as follows. 1. The loading limitation was represented as $60g{\cdot}COD/gm^2/day$ in experiment of simultaneous removal of organic matter and nitrogen. The maxmum COD % removal was 85% at the load $35g{\cdot}COD/m^2/day$. 2. The $NO_3-N$ % removal was approximately 80% at the load $60g{\cdot}COD/m^2/day$ and the maximum $NO_3-N$ remaval rate was $3.9g{\cdot}COD/m^2/day$ and the overall C/N ratio of 11.0 as required to achive 80% of $NO_3-N$% removal. 3.$NO_3-N$ removal rate was rapidly decreased above the load $7g{\cdot}NH_4{^+}-N/m^2/day$ and the maximum $NO_3-N$ removal rate was $3.7g{\cdot}NO_3-N/m^2/day$. 4. Irrespective of the recycle ratio, the COD % removal at the system of 2-stage RBC unit was nearly constant as 89% while the maximum one in the 1st-stage unit was 77% in the case of 50% recycle. 5. The maximum COD % removal in the 3-stage RBC system was 93% while 1st-stage one being 80%, under the $NH_4{^+}-N$ load of $7.4g/m^2{\cdot}d$. Also maximum percentage of nitrification and denitrification was 69% and 41% respectively, under the same $NH_4{^+}-N$ load.

The purpose of this study was to develop a recycling system for ozone off-gas. Although the ozone transmission rate of the injector method differs slightly depending on the ozone injection rate, it reaches approximately 99%, which is very high. During the increase in water inflow to the ozone recycling system from 2 L/min to 10 L/min, the average ozone recycling rate was 99.4% at a 1 ppm ozone injection rate, 98.6% at a 2 ppm ozone injection rate, 98.1% at a 3 ppm ozone injection rate. Ozone treatment facility operating costs can be divided into the costs of pure oxygen production, ozone production, and maintenance. The annual operating costs of ozone treatment facilities in Korea are estimated to be approximately 38.9 billion won. The annual savings are estimated to be approximately 5.8 billion won when the ozone transfer rate of the diffuser method, which is mostly employed in domestic water treatment plants, is 85% and 15% of the ozone is recycled.

Purpose: The purpose of this study is to investigate how sports fans' loyalty is built via CSR activities of professional sports teams. Furthermore, the study sought to suggest the model presenting the process of developing loyalty of sport fans by teams' CSR performance. Research design, data, and methodology: For this purpose, a survey was conducted on 450 professional sports fans through the convenience sampling method. A total of 357 of the data were used for the final analysis. Based on the collected data, frequency analysis, reliability analysis, confirmatory factor analysis, and structural equation model analysis were conducted. Results: The results showed that CSR activities contribute to building a positive image of team. Regarding fan identification, team image has also a positive effect on enhancing identification. The finding has supported the notion that attitudinal loyalty is enhanced by fan identification and further attitudinal loyalty significantly influences behavioural loyalty of fans. Conclusions: The results of this study explored the function of CSR of the teams on attitudinal and behavioural outcomes, loyalty. Moreover, the study suggested the constructual model presenting its role on enhancing fans' attitudes and behaviour affecting participation and consumption. Academic and practical implications were discussed for sport marketers and practitioners.
