        This study was conducted to obtain basic data on domestic wild Lanopila nipponica K specimens collected in Jeollanam-do from 2015 to 2017 to investigate the characteristics of fruit bodies and analyze their nutritional components. L. nipponica K. was mainly found near hills, such as in persimmon fields around hills, on mountain trails, and in bamboo fields. L. nipponica K. occurred from July to mid-October, especially after the rainy season or a typhoon, when the air humidity was increased. Rainfall occurred for 8–15 days during the 20 days before the collection date, and the average temperature was ≥ 23oC. The size of the fruit body was 12.3–28 cm, and the weight varied depending on the size; however, the fruit body was estimated to grow overnight, reaching the size observed at its discovery. As aging progressed, the surface of the fruit body cracked, and it turned dark after 6 days. Spores were lump-shaped when the surface was cut with a knife. When the soil on the surface of the site where the fruit body was located was scratched, a white thread-shaped mycelium expanded. At the time of collection, the flesh of the fruit body was white, but it turned brown and fluffy as maturity progressed. On the sixth day after the mushroom was generated, it produced a pungent odor and became friable, resembling a black cotton ball. The surface of the fruit body was white and had a circular or elliptical shape. Crude protein content tended to be high at 59% of the dry weight. The antioxidant activity, determined using the DPPH radical scavenging analysis method, was 167 vitamin C equivalents/100 g. The spores were brown, approximately 6 μm in size, with protrusions on their surface.

        Melons, a rich source of vitamins and fibers, are commonly grown in the soil. Hydroponic cultivation could improve yield and quality of melon and selection of substrate volume and the kind of substrates is important for hydroponic cultivation of melons. This study investigated the effect on melon growth according to volume of granular rockwool and substrates of coir and rockwool slab. ‘Geumsegye’ melon (Cucumis melo L. cv. Geumsegye) was cultivated hydroponically according to volume of granular rockwool to 1.0, 1.5, 2.0, 3.0, and 4.0 L, and was also cultivated using coir and rockwool slabs. Logistic model was applied to estimate the growth characteristics of melons such as plant height, leaf length, leaf width, and the characteristics of fruit. The growth characteristics of melons were significantly increased at 4.0 L compared to those grown of 1.0 L volume of on granular rockwool, and the results were the highest in coir and rockwool slabs. Melons grown in rockwool slabs showed the largest fruit fresh weight, fruit length, and fruit width. During hydroponic cultivation, growth characteristics of melon appropriate at the 4.0 L volume of granular rockwool, and the highest at coir and rockwool slabs. This study provides a basis for understanding the effect of root zone environment to the growth characteristics and fruit quality of non-netted melon.

        This study evaluated the sensory characteristics of sauerkraut prepared by adding 0.5, 1.0, 1.5, 2.0, and 2.5% (w/w) sea salt to cabbage. The quantitative descriptive analysis (QDA) and acceptance test of sauerkraut were determined for each salt concentration, and the principal component analysis (PCA) and partial least square regression (PLSR) analysis were performed to confirm the correlation between each factor. Results of the QDA determined 14 descriptive terms; furthermore, brightness and yellowness of appearance and the sour, salty, and bitter flavors differed significantly according to the salt concentration. Results from the PCA explained 22.56% PC1 and 65.34% PC2 of the total variation obtained. Sauerkraut prepared using 0.5, 1.0, and 1.5% sea salt had high brightness, moistness, sour odor, green odor, sour flavor, carbonation, hardness, chewiness, and crispness, whereas sauerkraut prepared with 2.0 and 2.5% sea salt had high yellowness, glossiness, salty flavor, sweet flavor, and bitter flavor. Hierarchical cluster analysis classified the products into two clusters: sauerkraut of 0.5, 1.0, and 1.5%, and sauerkraut of 2.0 and 2.5%. Results of PLSR determined that sauerkraut of 1.0 and 1.5% were the closest to texture, taste, and overall acceptance. We, therefore, conclude that sauerkrauts prepared using 1.0 and 1.5% sea salt have excellent characteristics in appearance, taste, and texture.

        This study investigated the factors affecting restrained and emotional eating according to the BMI of college women in Seoul. Based on their weight, 514 college women were divided into 3 groups. General demographics, nutrient consumption, eating habits and DEBQ were subsequently evaluated. Multiple regression analysis was performed to determine the factors responsible for restrained and emotional eating in each group. Percentage of the overweight or obese group having negative emotions, such as frequency of overeating (p<0.05), habitual eating, regret, and guilt after overeating, was higher as compared to the other groups (p<0.001). Considering factors that affect restrained eating, negative emotion after overeating had a positive correlation in the underweight group (β=0.481, p<0.001). In the normalweight group, the BMI (β=0.201, p<0.001), total food intake (β=0.241, p=0.002), and negative emotion after overeating (β=0.284, p<0.001) positively affected restrained eating. In the underweight group, habitual eating (β=0.292, p=0.002) and negative emotions after overeating (β=0.233, p=0.012) were determined to affect emotional eating. Moreover, habitual eating (β=0.290, p<0.001) and negative emotions after overeating (β=0.172, p=0.004) were observed to influence emotional eating in the normal weight group. In the overweight and obese groups, habitual eating was determined to affect emotional eating (β=0.410, p<0.001). Taken together, these results provide a basis for creating a weight control program for young women having undesirable eating behaviors, such as restrained and emotional eating.

        팽이버섯 생육용 톱밥배지 내 질소함량(1.2~1.8%)과 생육단계 중 억제기 온도(2, 4, 6 ̊C)에 따른 자실체 특성과 저장기간별 저장 특성을 조사하였다. 톱밥배지의 이화학성 분석 결과 배지 내 질소함량에 따른 pH, 탄소함량 등은 차이를 보이지 않았다. 자실체 생육 특성은 배지내 질소함량이 높아질수록 수량은 증가하는 경향을 보였다. 억제기온도의 경우 질소함량에 따라 자실체 생육에 미치는 경향이 달랐는데 질소함량이 1.28%로 낮은 T1의 경우 억 제기온도에 따른 자실체생육에 차이가 없었고 질소함량 1.5% 이상 배지에서는 억제기 온도가 낮을수록 수량과 갓, 대의 길이가 증가하는 것으로 나타났다. 저장기간에 따른 중량감소율은 배지 내 질소함량에 따른 변화는 관찰되지 않았고, 억제기 온도 4 ̊C이하에서 1.50~1.93%로 6 ̊C보다 낮은 중량감소율을 보였다. 자실체 갓 색도는 저장 31일 후 배지 내 질소함량이 높은 T3에 억제기 온도 4 ̊C처리 에서 L값 84.81, ΔE값이 6.3으로 다른 처리구에 비해 갈변도가 적은 것으로 나타났고 관능평가 또한 저장 31일 후에도 5.2점을 받아 판매 가능한 수준의 품질을 유지하였다. 하지만, 전체적인 결과를 봤을 때 배지 내 질소함량과 억제기 온도에 따른 상관관계는 나타나지 않았으며, 두 조건이 복합적으로 팽이버섯의 품질과 저장성에 영향을 끼치는 것으로 보인다. 따라서, 톱밥배지 내 질소함량 및 생육단계별 온·습도 조건에 따른 팽이버섯의 생육과 저장성 특성에 관한 추가적인 연구가 필요할 것으로 판단된다.
