This study was conducted to investigate the effects of Ge(germanium) treatment on rice quality. Rice samples were divided into the following treatment groups: control(CON: cultivated without Ge), Ge-1(cultivated with 200 kg of rough stone powder containing 1.6 mg/kg germanium per 10 ha), and Ge-2(cultivated with 500 kg of rough stone powder containing 1.6 mg/kg germanium per 10 ha). The mean total Ge level in the Ge-2 sample was 20.47 ppb. The levels of Ca and Na in the Ge-2 rice increased by 65.12 and 110.28%, respectively, when compared to the control, whereas the Zn, Mn, Fe, Mg and K content decreased by 11.44~30.50%. No significant difference in the percentage weight of C and O was observed among samples. The order of the percentage weight of P, S, and Cl was Ge-2>Ge-1>CON. The free amino acids were higher in samples from the Ge-1 and Ge-2 groups than in samples from the control. The GABA($\gamma$-aminobutyric acid) amount in the Ge-2 products was significantly high compared to other groups. The micro structure of Ge-2 showed a firmer network than the control and had a macroporous structure. Conversely, the Ge-2 products had higher scores for stickiness, hardness and overall taste when compared to the other groups. These results suggest that rice treated with rough stone powder containing germanium can be used in the production of commercially-desired functional rice.

Functional food for prevention of chronic diseases is one of this century's key global challenges. Cancer is not only the first or second leading cause of death in China and other countries across the world, but also has diet as one of the most important modifiable risk factors. Major dietary factors now known to promote cancer development are polished grain foods and low intake of fresh vegetables, with general importance for an unhealthy lifestyle and obesity. The strategies of cancer prevention in human being are increased consumption of functional foods like whole grains (brown rice, barley, and buckwheat) and by-products, as well some vegetables (bitter melon, garlic, onions, broccoli, and cabbage) and mushrooms (boletes and Tricholoma matsutake). In addition some beverages (green tea and coffee) may be protective. Southwest China (especially Yunnan Province) is a geographical area where functional crop production is closely related to the origins of human evolution with implications for anticancer influence.

The substantial use of fungal enzymes to degrade lignocellulosic plant biomass has widely been attributed to the extensive requirement of powerful enzyme-producing fungal strains. In this study, a two-step screening procedure for finding cellulolytic fungi, involving a miniaturized culture method with shake-flask fermentation, was proposed and demonstrated. We isolated 297 fungal strains from several cellulose-containing samples found in two different locations in Thailand. By using this screening strategy, we then selected 9 fungal strains based on their potential for cellulase production. Through sequence-based identification of these fungal isolates, 4 species in 4 genera were identified: Aspergillus terreus (3 strains: AG466, AG438 and AG499), Penicillium oxalicum (4 strains: AG452, AG496, AG498 and AG559), Talaromyces siamensis (1 strain: AG548) and Trichoderma afroharzianum (1 strain: AG500). After examining their lignocellulose degradation capacity, our data showed that P. oxalicum AG452 exhibited the highest glucose yield after saccharification of pretreated sugarcane trash, cassava pulp and coffee silverskin. In addition, Ta. siamensis AG548 produced the highest glucose yield after hydrolysis of pretreated sugarcane bagasse. Our study demonstrated that the proposed two-step screening strategy can be further applied for discovering potential cellulolytic fungi isolated from various environmental samples. Meanwhile, the fungal strains isolated in this study will prove useful in the bioconversion of agricultural lignocellulosic residues into valuable biotechnological products.

This study was undertaken to investigate the acute effect of caffeine consumption on the change of mineral concentration in serum and urinary mineral excretion in healthy young females. On two separate mornings at one week intervals, each subject drank a coffee which contained no caffeine and 3mg/kg body weight caffeine. To obviate dietary effects on mineral concentration in serum and urine, each subject fasted at least ten hours before consuming the test beverage. At one, two, three and four hours, serum and urine production collected seperately for measurement of sodium, potassium, calcium, phosphorus and magnesium concentration. The results were as following : 1) Mean age of subjects was 20.6$\pm$0.32, Mean body mass index of subjects was 21.64$\pm$0.89, which was within $\pm$10% of ideal body weight. 2) Total urine volume of caffein groups for 4 hour after caffeine consumption was higher than that of decaffeine one, but urine pH was unchanged after caffeine consumption. Total urinary four hour excretion of creatinine was not affected by caffeine consumption and creatinine clearance also was not different from the control value. 3) In serum, mean three hour content of sodium(p<0.01) and phosphorus was higher in the subject given the caffeine. Mean serum magnesium and calcium contents were lower in caffeine group than that of decaffeine one. Mean serum magnesium content for three hour after caffeine ingestion was affected by caffeine consumption(p<0.001). Mean serum content of potassium was unaffected by caffeine consumption. 4) Total urinary four hour excretion of sodium, increased significantly after caffeine consumption(p<0.05), while total urinary four hour excretion of potassium, calcium, phosphorus and magnesium was unchanged after caffeine intake. Urinary excretion of Na, Ca, P and Mg was greatest at one hour after caffeine consumption, especially urinary sodium and potassium excretion was significantly high(p<0.05, p<0.01). The above results show that only 3mg caffeine per kg body weight increase the urinary macro mineral excretion in healthy young females.

Objective: A study was conducted to develop non-dairy creamer analogs/mimics using egg white, egg yolk, soy protein and their combinations, and their nutrient content, shelf-life and flavor acceptability were compared. Methods: Spray dried egg white, egg yolk, and soy protein isolate were purchased from manufacturers and used for the formulae. Results: The protein contents of the non-dairy creamer analogs/mimics were about 8.5% as calculated. The amounts of oleic and linoleic acid content increased as the amount of yolk increased in the formula, but the increases of polyunsaturated fatty acids were <0.5% of total fat. Addition of egg yolk to the formula increased choline and lutein content in the products, but the amounts were <0.4 mg/g for choline and $4{\mu}g/g$ for lutein. The lutein in the products continued to decrease over the storage time, and only about 15% to 20% of the 0-month amounts were left after 3 months of storage. Although the thiobarbituric acid reactive substances values of the spray-dried non-dairy creamer analogs/mimics increased as storage time increased, the values were still low. Yellowness, darkness, and egg flavor/odor of the non-dairy creamer analogs/mimics increased as the amount of egg yolk in the formula increased. The overall acceptability of the non-dairy creamer analogs/mimics was closely related to the intensity of egg flavor/odor, but storage improved their overall acceptance because most of the off-odor volatiles disappeared during the storage. Water temperature was the most important parameter in dissolving spray-dried non-dairy creamer analogs/mimics, and $55^{\circ}C$ to $75^{\circ}C$ was the optimal water temperature conditions to dissolve them. Conclusion: Higher amounts of yolk and soy protein combinations in place of egg white reduced the cost of the products significantly and those products contained better and balanced nutrients than the commercial coffee creamers. However, off-flavor and solubility were two important issues in the products.

The purpose of this research is to strengthen rural community empowerment by creating a tourism farm as a plan to reduce relative poverty and to improve the quality of life by creating jobs and increasing the income of local residents in underdeveloped countries. To do so, literature review, stakeholder interviews, on-site investigations, focus-group interviews, a project meeting for residents and a questionnaire survey were performed and analyzed and the results were as follows. First, Uganda has the potential to increase agricultural production based on its warm climate, fertile land and abundant natural resources. The quality of life of local residents is expected to be improved by realizing high-added values through the convergence of the conventional existing agricultural industry and other industries if the agricultural technology is properly transferred based on abundant labor force and low labor expenses. Opportunities for the success of the project can be spread to other rural villages across the country. Second, since local residents are now cultivating sugar cane, cassava, matoke, banana, coffee and so on as a farm owner, tourism agriculture with high-added values can be promoted by vitalizing communities based on farming technology to be transferred and a cooperative farm. It is also necessary to implement a rural community empowerment project to do so. Third, the university that is the cooperative partner of the project is positively considering to train experts by establishing a community development department, and, if necessary, a technical training center to educate the general public, which is expected to create synergic effects through the convergence of education, agriculture and tourism.

본 연구는 청계천 공간의 역사적 변화 시기마다 미디어 담론이 청계천 공간 생산과 어떻게 관련을 맺게 되는지에 대해 관심을 갖고 담론분석을 시도하였다. 특히, 청계천 공간의 생산과 미디어 담론의 관계 속에서 사람들의 경험과 인식을 특정 방향으로 유도하는 담론의 규칙성을 찾는 작업에 주력하였으며, 그 결과 청계천 복원을 자본주의 확장 과정에서의 공간 생산과정으로 해석하게 되었다. 1960년대 미디어 담론의 하나로서 전근대적 육체와 시설이 시간의 효율성으로 쪼개진 공간을 실천하면서 근대적이고 도시적인 '일상'으로 전환되는 부분이 관찰되었다. 이후 1980년대의 담론 중에서 청계천은 '도심 부적격 시설'이 밀집된 공간으로 재현되는 경우들이 있었는데, 이 시기에는 세계적 경기 침체의 영향을 받으며 자본축적의 기능을 원활하게 수행하지 못하게 된 청계천 공간에서 이질적인 정체성이 형성되어 있음을 알 수 있었다. 이질적인 정체성이란 다시 말해, 청계천 공구상가의 구조적 양식을 잉태한 청계천 공간의 '장소성'으로서, 담론화 과정을 통해 자본 축적의 효율성을 담당하지 못하고 있었던 청계천 공간에 대한 '평가절하' 및 '가치파괴'로 재현되었고, 2000-이후 환경 및 역사를 복원하고자 하는 사람들의 '상상'으로 이어져 청계천 복원을 이끌어 내게 되었다. 2005-복원된 청계천 공간은 청계천에 흐르는 물과 녹색 풍경, 역사적 구조물, 문화시설 등의 기표들을 통해 하나의 신화를 만들어내는데, 이러한 신화 속에서 사람들은 자연스럽게 동질화된 소비 패턴을 실천하게 된다는 점에 주목하게 된다. 이는 생산의 시대에서 소비의 시대로 전환하는 자본주의적 생산양식을 의도적으로 혹은 비의도적으로 담론화 하는 과정의 일부라고 볼 수 있다.
