  • A Comparative study was performed among five Korean wheat(Greu, Eunpa, Tapdong, Allgreu, Woori) and three imported wheat(Dark Northern Spring, Austrian Standard Wheat, Western White) to investigate the characteristics of minerals and phytate from Korean wheat varieties. Ash contents of kernel was higher in Korean wheat than in imported wheat and related to ash contents and darkness of flour. More contents of Fe, P, and Mg from Korean wheat grains and Fe from Korean wheat flours were observed in comparison to imported wheat varieties. Fe concentration in Korean flour show high, indicating Fe was distributed at endosperm layer of kernels and not eliminated with milling. In addition, phytate affecting availability of minerals was determined from kernels and flours. Even though Korean wheat kernels had more phytate than that of imported wheat kernels, it is believed that most of phytate was removed with milling and there was no major difference between Korean and imported wheat flours. We also observed that the content of phosphate closely parallels the content of phytate from both the flours and kernels.

  • Oysters, especially are excellent source of several mineral including iron, zinc and selenium, which are often low in the mordern diet. They are also an excellent source of glycogen, vitamin B12 and considered the healthiest when eaten raw on the half shell in good tasted season from November to March. This study was investigated for the purpose of obtaining basic data which can be applied to processing of two kinds of canned boiled oyster (canned boiled oyster, canned boiled oyster in bamboo salt). Shucked oyster meat was cooked in steam (15min) after washing with water, filled 90g into can (301-3), added with salt solution and then precooked for 10 min. at $100^{\circ}C$. Canned boiled oyster was added 1.5% salt solution 60mL. Canned boiled oyster in bamboo salt was added 0.5% salt solution 30mL and 0.7% bamboo salt solution 30mL. The cans were seamed using a vacuum seamer, and then sterilized for various Fo values (Fo 8~12 min.) in a steam system retort at $116^{\circ}C$, $118^{\circ}C$. Viable bacterial count, proximate composition, pH, salinity, yield, VBN, amino-N, TBA, mineral, color value, free amino acid, hardness and sensory evaluation of two kinds of canned boiled oyster produced at various sterilization condition (Fo 8~12 min.) were measured after divide to meat and juice. The results showed that canned boiled oyster in bamboo salt sterilized at Fo 8 min. was the most desirable because this condition is the most economical and tasty.

  • Interest in the origin of the universe and man has historically been one of the central themes of human inquiry. The question of origin is not just a matter of intellectual curiosity, but a matter of human identity and an important matter of human destiny. The traditional model presented in relation to the origin of man is largely the Christian creationism that all things originated from the Creator, the evolutionary theory that everything happened by chance and evolved from lower to higher animals, and the agnosticism that we cannot know anything about the origin. This study deals with the theory of theistic evolution, a combination of creationism and evolutionism. It is argued that the theory of the evolutionary origin was not an immediate creation, although all things originated from God, but through creation through a long evolutionary process. The theory of theistic evolution was proposed by combining two conflicting theories of origin in a Christian way, which has several essential problems, but this study pointed out two. First, the God of the Bible is reduced to the image of being confined to the laws of nature, not the Almighty Creator. Second, by interpreting the events of the Bible symbolically, it results in rejection of historicity. Therefore, it is more rational to choose either evolutionism or creationism rather than the theory of theistic evolution.

Critical Study on Mattheo Ricci's Accommodation and Naturalization Focusing on Changes in the Concepts of Di(Emperor Above) and Tian(Heaven) (마테오 리치의 적응주의적 보유론에 관한 비평적 고찰: 제(帝), 천(天)개념의 변천사를 중심으로)

  • The Accommodational missionary method adopted by the Jesuit missionaries who came to China in the late Ming and early Qing dynasty is called the Accommodation and Naturalization and is based on the Poetry. The terms they borrowed were 'Di(Emperor Above)' and 'Tian(The heaven)', the key terms of Confucianism. Although 'Di' was a new transcendent concept, its status was downgraded in the political upheaval, and 'Tian' was rather elevated. However, both of these concepts gradually transformed into philosophical concepts that directly affect real life. The two terms borrowed to express the priesthood could not contain the uniqueness of Christianity, and Christianity was interpreted as an extension line of Confucianism thinking, reduced to an adjunct of Confucianism, and was not indigenous to the depth of ideology. A rational philosophical inquiry could not have played a full role in guiding the Chinese into the true Christian 'faith' unless it is paired with the great teachings of revelation. It is necessary to analyze these results soberly to find problems and to try various studies to explore ways to open up new horizon for Christian missionary work.

  • This study was conducted to investigate the physicochemical quality properties and provide basic data for the activation of traditional Kamju of juice type product prepared by mixing malt and extruded rice collet powder. Malt extracts were prepared by extracting the mixture of malt and water at a weight ratio of 25:75 after soaking for 2 h at $45^{\circ}C$. Rice collet powder was prepared by adjusting the barrel temperature to $95^{\circ}C$, screw speed to $3.07{\times}g$, discharge port diameter to 7 mm and a raw material input to 50 kg/h, the powder was then ground to a particle size of 80 mesh. The physicochemical characteristics (pH, color, viscosity, reducing sugars, number of viable cells, free amino acids) and sensory evaluations were conducted at various time points during the saccharification and at different mixing ratios of the extruded rice collet powder to malt extract (5:95, 15:85, 25:75, 35:65, each at $55^{\circ}C$ for 9 h). As a result, with an increase in the proportion of the extruded rice collet powder and saccharification time, the physicochemical properties of traditional Kamju significantly improved (p<0.05). A mixing ratio of 35:65 rice collet powder to malt extract and a saccharification time of 9 h were found to be the most desirable conditions. However, based on the sensory evaluation, a mixing ratio of rice collet powder and malt extract of 25:75 and a saccharification time of 5 h resulted in the most preferable palatability of traditional Kamju (p<0.05). Therefore, the mixing ratio and saccharification time should be determined to provide a better choice with respect to the taste and economic aspects of traditional Kamju.

  • Fermented anchovy of the favorite sea food in Korea made from anchovy (Engraulis japonica) and salt. The study was undertaken to investigate the effects of different retorting conditions on the quality of canned salt-fermented anchovy fillet. The salt fermented anchovy fillet was prepared by fermenting anchovy(Engraulis japonica) with salt(15%) at $5^{\circ}C$ for 15 days and then cold air drying the fermented fillet for 1 hour. The dried fermented anchovy fillet(85g) was filled with olive oil(60g) into can(301-1) and seamed using a vacuum seamer, and then sterilized at Fo 9 and 11 mins in a steam system retort at 12 $1^{\circ}C$, respectively. After sterilization with different heating conditions, the pH, VBN, amino-N, color value (L, a, b), texture profile, TBA value, sensory evaluation and viable bacterial count of the canned salt-fermented anchovy fillet were measured. In both sterilized cans, the viable bacterial counts were not detected. There was no remarkable difference in physicochemical and sensory quality between sterilization conditions. The results showed that sterilization of Fo 9 min was more desirable than that of Fo 11 min to prepare canned salt-fermented anchovy fillet.

  • The protective effect of Pteridium aquilinum on high glucose-induced cytotoxicity was examined in vitro to investigate the relationship between diabetic condition and neuronal dysfunction. The ethyl acetate fraction of P. aquilinum (EFPA), with total phenolic content of 265.08 mg gallic acid equivalent/g, showed higher 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)/2,2-diphenyl-1-picrylhydrazyl radical scavenging activities and lipid peroxidation inhibitory effect than any other fraction. In addition, EFPA showed a significant reduction in the inhibitory effect on ${\alpha}$-glucosidase activity ($IC_{50}$ value=$205.26{\mu}g/mL$) compared to the acarbose positive control. The anti-oxidative effect in PC12 cells, protective effects on high glucose-induced oxidative stress in neuronal cells, and neurotoxicity were measured using 2',7'-dichlorofluorescin diacetate, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazoliumbromide, and lactate dehydrogenase assays, respectively. EFPA showed conspicuous inhibitory effect on cellular reactive oxygen species production and neuronal cell apoptosis. Finally, kaempferol-3-glucoside was identified as the main phenolic compound of EFPA using high performance liquid chromatography.
