재래식 간장의 맛을 개선하기 위하여 대두 자숙액, 당 및 젖산균과 효모를 접종하고 자연조건에서 발효시키면서 젖산발효와 알코올발효 효과를 조사하였다. 젖산균과 효모 접종구에서 젖산의 생성량이 2.91%로 가장 높았고, 그 다음이 간장 덧에 당만을 첨가한 구에서 2.38%, 대두 자숙액 만을 첨가한 대조구에서 2.05%로 나타나 모든구의 간장에서 젖산발효의 효과가 있었으나, 알코올은 모든 처리구에서 소량 검출되어 젖산균에 의해 생성된 초산 때문에 효모의 생육이 저해되어서 알코올발효 효과는 없는 것으로 나타났다. 기호도에서도 젖산균과 효모 접종구와 당 첨가구가 우수하였다.

This study investigated the growth and chlorophyll fluorescence reactions of three Ardisia genus grown under various indoor light intensity conditions with the aim of evaluating their suitability as indoor plants. Young seedlings of A. crispa (Thunb.) A.DC., A. pusilla DC., and A. japonica (Thunb.) Blume were used in the experiment. The plants were cultivated indoors for 10 weeks under different light intensities: 10, 50, 100, and 200 PPFD (μmol·m^-2·s^-1), and their growth was compared with that of plants cultivated in a greenhouse during the same period (mean value 236.8±20.4 PPFD at noon). Also, chlorophyll fluorescence analysis was investigated with a portable PAM fluorometer. The indoor plants were maintained at 12/12 h photoperiod, temperature at 25±1℃, and humidity at 55±3%. Irrigation frequency (once every three days) was the same for the indoors and the greenhouse. The results of growth in three Ardisia plants showed that almost all parameters except leaf number and chlorophyll content had similar levels regardless of light intensity. A. crispa and A. pusilla plants grown in 200 PPFD were investigated to have low chlorophyll contents. Meanwhile, chlorophyll fluorescence parameters differed based on light levels. In A. crispa, the Fv/Fm (0.77), DIo/RC (0.47) and Fm/Fo (4.77) parameters tended to be poor at 200 PPFD compared to those at other light intensities. Similarly, the DIo/RC, Fm/Fo, and Pi_Abs parameters of A. pusilla plant (200 PPFD) are 0.45, 4.48 and 2.42, respectively, which can be considered stress. The analysis of fluorescence in A. japonica showed that all parameters except ETo/RC had similar levels regardless of light intensity. The ETo/RC parameter was 0.49 and 0.72 in the control plants and plants 200 PPFD, respectively, which was lower than those in plants at other light intensities. Therefore, it seems that the relatively high light intensity acted as a stressor for Ardisia plants.

Though there is an on-going need for the diversity of ornamental plants for in-door environment, their growth and stress adaptability in comparatively low light intensity condition require further studies for implementation. Here investigates the growth and chlorophyll fluorescence parameters of Farfugium japonicum (L.) Kitam, Liriope muscari (Decne.) L.H.Bailey and Acorus gramineus Aiton under several light intensities which were based on common in-door environment. The growth measurement of the plants included the quantity, length, width and SPAD value of the leaves. Calculated values of Fm/Fo, Fv/Fm, Pi_Abs, ETo/RC and DIo/RC were used as the parameters of the chlorophyll fluorescence under 10, 50, 100 and 200 PPFD (μmol·m^-2·s^-1) light intensities. In-door plants group was put in a closed room allowing no other light sources for 10 weeks and the control group was put in glass-greenhouse for the same period. The overall in-door growth of L. muscari was not significantly different in all light intensities compared to the control group and even showed the higher SPAD values. Also, an increasing tendency of Pi_Abs value under 10 to 100 PPFD was observed implying that L.muscari could adapt well to in-door environment. Measurement of A. gramineus growth mostly showed the highest values in the control group especially in the number of the leaves. Nevertheless, chlorophyll fluorescence parameters showed no significant value difference between in-door and the control groups and thus, A. gramineus might have possibility of successful adaptation to in-door environment. F. japonicum showed deficient growth in plant height and leaf length compared to the control but, it seemed to be able to sustain ornamental value under in-door light intensities. Furthermore, Pi_Abs and DIo/RC values were increased under in-door light conditions suggesting potential adaptability of F. japonicum.

White rose petal extract (WRE) contains large amounts of phenolic compounds and is considered edible. In this study, red and white wines were prepared by the addition of WRE (0.10% or 0.25% (w/v)), followed by fermentation at $25^{\circ}C$ for 15 days. The fermentation profiles, colors, sensory test results, and antioxidant activities of the wines were compared. As reported herein, the fermentation profiles of the pH, $CO_2$ production rate, and final ethanol concentration were not affected by the addition of WRE, but a slow consumption rate of sugar was observed in 0.25% WRE-added wine. In contrast, the total polyphenol concentrations in WRE-added wines increased significantly (p < 0.05) in a dose-dependent manner, resulting in appreciable enhancement of the antioxidant activities of the wines. Chromaticity tests showed slight changes in the redness and yellowness, but sensory tests showed that the overall flavor qualities of the WRE-added wines were acceptable to the panels. This study demonstrates that addition of WRE to wine confers beneficial health effects and this treatment results in better outcome in white wine.

한국의 곤충 산업은 2010 년부터 "곤충 산업 육성 및 지원에 관한 법률"에 의해 지원을 받았다. 이 법에 의거해 곤충을 사육하는 사람도 '농업인'으로 자격이 있다. 그러나 곤충 산업은 '농업' 및 '농업인', '농산물'과 같은 모든 개념을 정의하는 "농업 농촌 및 식품산업 기본법"에 포함되지 않는다. 법적으로 엄격하게 말하면, 곤충 산업이 농업에 포함되지 않는다는 논쟁이 제기 될 때마다 곤충 산업을 지지할 방법이 없기 때문에 곤충을 사육하는 사람들은 모든 농업 지원과 정부의 보조금을 받을 법적 근거가 부족하다. 따라서 관련 법규를 개정하여 곤충 산업의 법적 지위를 명확히 할 필요가 있다.

Food sovereignty is the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems. An increase in the price of food that occurs as a result of increased demand from human consumption and use as an alternative energy resource. Furthermore, agflation, a combination of the words "agriculture" and "inflation", will also affect non-vegetative foods as the price increases for grain will make livestock feed more expensive as well. Food sovereignty implies new social relations free of oppression and inequality between men and women, peoples, racial groups, social classes and generations.

In an ongoing survey of Korean indigenous fungi, two fungal strains (KNU16-74 and KNU16-99) belonging to the genus Chrysosporium were isolated from field soil in Gyeongnam, Korea. Morphological characterization and phylogenetic analysis using sequence of the internal transcribed spacer regions were carried out to confirm its precise identification. These strains were identified as Chrysosporium indicum (KNU16-74) and Chrysosporium fluviale (KNU16-99). To examine the keratin degradation efficiency of these two fungal species, human hair strands were incubated with fungus culture. Results revealed that these two fungal species have the ability to degrade keratin substrate. This is the first report of these two species in Korea.

Objectives : Samhwangsasim-tang (SST), Hwangryeonhaedok-tang (HHT), Ukgan-san (UGS), Onjunghwadam-hwan (OHH) and Samul-tang (SMT) have been used for the treatment of various diseases. This study was performed to compare the anti-obesity effects of 5 herbal formulas in high fat diet-(HFD) induced obese mice. Methods : The mice were randomly divided into seven groups that were fed a normal diet (ND), a HFD, a HFD plus SST (HFD + SST), a HFD plus HHT (HFD + HHT), a HFD plus UGS (HFD + UGS), a HFD plus OHH (HFD + OHH), or HFD plus SMT (HFD + SMT) at 300 mg/kg/day for 7 weeks. All groups were assayed for body weights, food efficiency ratio (FER), final liver and fat weight and blood biochemical parameters. Results : The increased body weights, food efficiency ratio (FER), and serum total triglyceride were decreased in HFD + OHH group relative to the same measurements in HFD group. Furthermore, the HFD + SST group significantly reduced FER, liver and abdominal subcutaneous fat weight gains, and serum total triglyceride, whereas HDL-cholesterol level was increased compared to HFD group. Conclusions : These results suggested that HFD + OHH and HFD + SST exert anti-obesity effects in HFD-induced obese mice.

This study was conducted to investigate the effects of $Megazone^{(R)}$ (a mineral mix) supplementation on growth performance, nutrients digestibility, blood characteristics, meat quality and carcass traits in weaning-to-finishing pigs. A total of 48 crossbred $(Landrace{\times}Yorkshire{\times}Duroc)$ pigs with initial body weight (BW) of $4.46{\pm}0.18kg$ were used in a 21 wks trial. Pigs were blocked by weight and allotted to two dietary treatments in a completly randomized design. There were 6 pens per treatment. Dietary treatments included: 1) Control (CON: basal diet) and 2) MT (basal diet+0.8% $Megazone^{(R)}$). Through the entire experimental period, there were no effects of dietary $Megazone^{(R)}$ supplementation on growth performance nutrients digestibility, blood characteristics and meat quality traits (p>0.05). Market weight and backfat thickness also had no differences between the two treatments (p>0.05). However, carcass weight and carcass ratio in MT treatment were improved significantly compared with CON treatment (p<0.05). In conclusion, supplmentation of $Megazone^{(R)}$ can increase carcass weight and carcass ratio in weaning-to-finishing pigs, however, it has no effects on growth performance, nutrients digestibility, blood characteristics and meat quality traits.
