In the period of Japanese occupation comic narratives were popular to such an extent as to be published not only newspapers and magazines but also books as 『Yojigyeong』(1910), 『Jeodobaekhwa』(1912), 『Gaegeonhuihui』(1912), 『Angcheondaeso』(1913), 『Kkalkkaluseum』(1916), 『Socheonsoji』(1918), 『Gogeumgidamjip』(1923), 『Mangogidam』(1924), 『Joseonpaldo iksal & jaedam』(1927), 『Segyesohwajip』(1934). This study is to discuss about how those narratives gain modernity with the titles scattered in 『Byeolgeongon』 as the central figure, and to reveal the nature of the comic narratives in 『Byeolgeongon』 by looking into contents. The comic narratives in the magazine are 149, especially from the titles show the editors' agony at that time. The narratives gain modernity by combining the new trend cultural terms which can't be found in our traditional culture as 'sinbu huboja jeonramhwoe.', 'sinrang huboja jeonramhoe.', 'nonsense teuksseolgwan', 'how modern shipbuilding 10 inventions sinjejo', 'sohwabangsongsil', 'sohwabangsongguk', 'freedom march', 'sinchunpoksodaehwoe' and 'humor orchestra'. The narratives give laughter to the readers by carrying the characters such as wit, enlightenment, critics of social conditions, grotesque. The narratives in the magazine 『Byeolgeongon』 represent much to survive with comic story in a time of gloom in the period of Japanese occupation.

Olon Ovoot gold mine, Mongolia, is located in the Omnogobi province which is south 500 km from Ulaanbaatar. The mine area consists of the Devonian Bot-Uul khudag formation, the Upper Devonian intrusions, and the Upper Devonian or the Early Jurassic quartz veins. The quartz veins contain from 1 to 32 g/t gold with an average of 5 g/t gold. The quartz veins vary from 0.2 m to 25 m and are concordant or discordant with foliation of the green-schist. The mineralogy of the quartz veins is simple and consists of mainly of white massive quartz with partly transparent quartz in cavity. Quartz, sericite, chlorite, pyrite and carbonates(ankerite, dolomite and siderite) were observed in the alteration zone. Carbonate minerals occur as disseminated, coarse or fine grains with quartz, sericite, chlorite and pyrite near vein margin or within wall-rock xenoliths in quartz vein. Ankerite is present as later dark grey ankerite(13.51 to 16.89 wt.% FeO) and early white grey ankerite(16.67 to 19.90 wt.% FeO). The FeO contents of early ankerite are higher than those of later ankerite. Dolomite contains from 3.89 to 10.44 wt.% FeO and from 0.10 to 0.47 wt.% MnO. Dolomite is present as dark grey dolomite(4.06 to 6.87 wt.% FeO), light white grey dolomite(6.74 to 7.58 wt.% FeO) and grey white dolomite(7.33 to 10.44 wt.% FeO). The FeO contents of white grey dolomite are higher than those of dark grey dolomite. Siderite contains from 34.25 to 48.66 wt.% FeO, from 6.79 to 14.38 wt.% MgO, from 0.06 to 0.26 wt.% MnO and from 2.08 to 8.08 wt.% CaO.

Purpose: In this study, we evaluated the physical and thermal properties of the compositions made by blending glass fiber (GF) of different contents into glass fiber polyamide-66, and investigated if the compositions applying to the glasses frame to replace the TR-90, which is polyamide-12 resin used as an injection-type spectacle frame material. Methods: To investigate the characteristics change of polyamide-66 (PA-66) compositions with the change of the content of glass fibers, we produced a composition of the content by using a twin-screw extruder. The mechanical strength of the composition production was measured and coating properties as well as cutting processability were evaluated. We evaluated the applicability of the glasses frame by comparison the results of new compositions with characterizations of traditional TR. Results: For the results of the characterization of Polyamide-66/GF composition, we found that the higher increase of content of the glass fiber, the less mold shrinkage rate, and the mechanical strength was increased. Tensile strength increased from $498kg/cm^2$ for 0 wt% of the content of the glass fibers to $849kg/cm^2$ for 30 wt% of the content of the glass fibers. As a result of a coating evaluation, the strength of coating was 4B in the GF 5wt% and 5B, which was extremely good coating characteristics, in the over than GF 5 wt%. Conclusions: In case that 30 wt% of the glass fiber was blended, the mechanical strength was greatly improved, the hardness was increased, injection temperature increased due to increase of the viscosity, and the flow mark of the product may occur. The paint coating of PA-66 blended with glass fiber was all excellent. With general evaluating physical properties and workability properties it was determined that around 10 wt% of the content of the glass fibers was possible to apply a spectacle frame.

The purpose of this study was to investigate the biological benefits of apple peel. The antioxidant and anti-inflammatory activities of a 70% ethanol extract of apple peel were examined. The total phenolic compound and flavonoid contents of apple peel were $6.8{\pm}0.5mg$ gallic acid equivalent/g of fresh weight and $3.3{\pm}0.3mg$ catechin equivalent/g of fresh weight, respectively. Antioxidant activity was evaluated by measuring 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. The DPPH radical scavenging activity of apple peel was $18.9{\pm}1.6$, $46.3{\pm}2.3$ and $58.1{\pm}3.9%$ at concentrations of 0.1, 0.5 and 1.0 mg/mL, respectively (p<0.05). The anti-inflammatory effect was investigated by measuring the inhibition of inflammatory enzymes. Apple peel significantly inhibited secretory phospholipase, cyclooxygenase-1, cyclooxygenase-2, and lipoxygenase activity by up to $53.5{\pm}2.3$, $13.4{\pm}1.8$, $64.8{\pm}5.4$ and $44.4{\pm}4.5%$, respectively (p<0.05). Taken together, these findings suggest that apple peel may act as an antioxidant by radical scavenging and may possess potential anti-inflammatory properties for suppressing the activity of inflammatory enzymes. These results also suggest that apple peel can be utilized as a health functional food ingredient possessing antioxidant and anti-inflammatory activities.

Nutritional compositions of three Tochukaso species (Paecilomyces tenuipes hosted by Larva and pupa, Cordyceps militaris, C. sinensis) were compared. Fruiting body and host fractions were separately analyzed. Fruiting body fraction of P. tenuipes (36.6%) hosted by larva was higher than that hosted by pupa (10.2%), an indication that the quality of the former is superior to the latter. Carbohydrate content of C. sinensis (39.6%) was $2.5{\sim}7$ times higher than those of others, probably due to the presence of polysaccharides. Protein and crude lipid contents of C. sinensis and C. militaris were 25.8 and 10.3%, and 75.1 and 3.9%, respectively. C. sinensis showed the lowest Ca content and $30{\sim}75$ times higher Fe content among the samples tested. Vitamin A content of C. militaris was 308.9 IU/100g, two fold higher than those of the other species. Saturated fatty acid content was the highest in P. tenuipes (pupa, 27.7%), whereas unsaturated fatty acid was the highest in P. tenuipes (larva, 83.3%). Aspartic acid, glutamic acid, and glycine were abundant in all species. Cordycepin content of C. militaris was $20{\sim}50$ times higher than those of the other species.

Quality changes in citron (Citrus junos) during storage were studied to investigate the efficiency, cooling properties and the washing and storage effects of hydrocooling method. As a result of plotting the nondimensionalized citron temperature versus cooling time, its cooling rate coefficient was shown to be $-0.012\;min^4{\sim}\;-0.017\;min^4\;(R^2=0.97{\sim}0.99)$ at center, and to be $-0.033\;min^4{\sim}\;0.075\;min^4\;(R^2=0.89{\sim}0.93)$ at surface. During storage, weight loss was more affected by storage temperature than by pretreatment condition and in reached $22{\sim}23%$ after 7 weeks at $15^{\circ}C\;and\;10{\sim}11%$ after 8 weeks at $5^{\circ}C$ in all samples. However, changes in moisture contents of hydrocooled citron were shown to be about $1{\sim}2%$ after 7 weeks while that of non-treated citron was about 3% after 1 week of storage at $5^{\circ}C$. And the change of pH, acidity and soluble solid content were not significantly different between each treatments during storage $5^{\circ}C\;and\;15^{\circ}C$. Changes in Hunter L, a, and b values of hydrocooled citron were lower than those of non-treated one as the storage time increased. The respiration rate of hydrocooled citron during storage at $15^{\circ}C$ was $103.63\;mg{\cdot}CO_2/kg{\cdot}hr$, which is about 50% of that of non-treated citron.

Horse fat was extracted from fatty horse meat at $70^{\circ}C$ under vacuum conditions. The oxidative stability of horse fat was investigated by the addition of 0, 30, 60, and 150 mg/kg of ${\alpha}$-, ${\gamma}$-, or ${\delta}$-tocopherol during storage of 14 days at $65^{\circ}C$ in the dark. Changes of tocopherol concentration and fatty acid composition, peroxide value, and 2-thiobarbituric acid (TBA) value were analyzed during storage. The levels of the added tocopherols were found to decrease during storage. Unsaturated fatty acids contents of horse fat without tocopherol decreased from 60.87% to 57.22% after 14 days. The peroxide value and TBA value increased as storage time increased. The peroxide values of horse fat after addition of 0, 30, 60, and 150 mg/kg of ${\gamma}$-tocopherol were 43.75, 25.17, 20.87, and 15.41 meq/kg, respectively, and the TBA values were 7.87, 5.64, 4.43, and 4.23 mg malonaldehyde (MA)/kg, respectively, after 14 days. At the concentration of 150 mg/kg, both ${\gamma}$- and ${\delta}$-tocopherol impeded the oxidation of horse fat during storage.

This study was conducted to investigate the effects of supplementation of dietary betaine on nutrient digestibility and physiological responses in finishing pigs. A total of twelve pigs with a body weight of $80.1{\pm}3.7kg$ were individually caged, and randomly assigned to one of the two experimental diets containing 0 (control) or 5 g/kg (treatment) of the betaine in a $2{\times}2$ Latin square design. The experimental period was 14 days-7 days adaptation and 7 days trial period-per phase. All data for the difference between control and treatment groups were statistically analyzed by student's t-test. Dry matter and crude protein digestibility in the treatment group were significantly improved by 1% and 1.3%, respectively, as compared with those in the control (p<0.05). The apparent absorption of dietary energy was increased from 82.3% to 83.7% by dietary betaine supplementation. Thus, the retention of energy was also significantly increased to above 6% in the treatment group compared with the control group (control 4,057 vs treatment 4,314 kcal; p<0.01). The physiological parameters indicating serum biochemical contents and stress-, immune-, and inflammatory- responses were not changed by the supplementation of dietary betaine. In conclusion, dietary betaine improves the nutrient digestibility without any negative effects in terms of physiology in finishing pigs. It suggests that the supplementation of dietary betaine may increase the productivity through the improvement of weight gain and feeding efficiency.

Removal of monochloropropanediol (MCPD) and improvement of quality of the soy-sauce made from acid-hydrolyzate of defatted soy protein (SAHSP) were examined by fermenting the soy-sauce with soy-sauce koji or koji plus Pediococcus soya or/and Saccharomyces rouxii. The overall fermentation process performed in this work consisted sequentially of autodigestion of soy-sauce koji $(at\;45^{\circ}C\;for\;12\;days)$, lactic acid fermentation $(at\;30^{\circ}C\;for\;14\;days\;in\;S3\;and\;S4)$, ethanol fermentation $(at\;30^{\circ}C\;for\;14\;days\;in\;S2\;and\;S4)$,and aging $(at\;25^{\circ}C\;for\;20\;days)$. At the end of the autodigestion period, the highest MCPD removal (from the initial 38.6 ppm to 1.3 ppm) was observed in the S-2. Reducing sugar contents of the S-2 and S-4 sharply decreased from the 30th day of incubation, from the initial concentration of about 5.0% to less than 0.5% at the end of the process. Total soluble nitrogen content of all the soy-sauce products slightly increased during the overall fermentating period.The level of free glutamic acid, a major amino acid that is known to determine the taste of soy-sauce was determined to be an average value of $1270{\sim}1323\;mg/100\;mL$ of soy-sauce. The results of sensory evaluation of the fermented SAHSPs show that qualities of the S-2 and S-4 samples are nearly on the same level with that of the commercially fermented soy-sauce (p<0.05). This result suggests that the fermentation process in this work, especially the process performed with S. rouxii has a good effect for removing MCPD from SAHSP and also for improving quality of the SAHSP product.

Quality changes in carrot during storage were studied to investigate the efficiency, cooling properties and the washing and storage effects of hydrocooling method. As a result of plotting the nondimensionalized carrot temperature versus cooling time, its cooling rate coefficient was shown $-0.0171min^{-1}{\sim}-0.0121min^{-1}\;(R^{2}=0.99{\sim}0.95)$, and $-0.141min^{-1}{\sim}-0.0038min^{-1}\;(R^{2}=0.98{\sim}0.92)$ in package condition7. Rate of weight loss and change in moisture content of carrot were not significantly different by treatment conditions during storage at $5^{\circ}C$. During storage at $15^{\circ}C$, however, weight loss of hydrocooled carrot was lower than that of non-treated carrot from the 30th to 40th day. Especially, PE was more effective than tray for packaging hydrocooled carrots. Carrot pretreated wish sterilizing agent, packed with PE vinyl film and with residual water removed after hydrocooling showed a lower decaying-rate than any other carrots. Changes in Hunter L and b values of hydrocooled carrot were slower than those of non-treated one. The carotenoids contents of stored carrot $(0.736{\sim}0.780mg%)$ decreased to $9{\sim}43%$ after 40 days of storage at $5^{\circ}C$ and before 20 days of storage at $15^{\circ}C$. It could be presumed that the addition of sterilizing agent reduced the initial level of overall microbial and coliform counts and their growth rate during storage.
