목적: 본 연구의 목적은 운동심상 훈련이 심폐 기능에 미치는 효과를 확인하는 것이다. 방법: 본 연구는 20대 성인 남성 26명을 대상으로 실시하였다. 참가자는 각각 13명의 참가자를 고려하여 운동심상 훈련 군과 대조군으로 무작위로 할당되었다. 측정 방법으로는 트레드밀에서 심장부하 검사를 실시하였고, 최대산소섭취량, 운동 시간 및 회복 심박수를 측정하였다. 운동심상 훈련군은 일주일에 5번 운동심상 훈련을 적용하였다. 본 연구에서는 군 내 결과를 확인 하기 위하여 대응 t 검증을 하였고, 군간 비교를 위하여 독립 t검증을 실시하였다. 결과: 최대 산소 섭취량은 각 군의 전후 비교와 각 군 간의 비교에서 유의한 차이를 보였다. 운동심상 훈련군은 대조군에 비해 운동시간에 유의한 변화가 있었다. 회복 심박수에는 유의한 차이가 없었다. 결론: 본 연구에서는 운동심상 훈련군에서 최대산소섭취량 및 운동 시간을 개선하지만 회복 심박수에는 영향을 미치지 않는 것으로 나타났다. 따라서 운동심상 훈련은 심폐 기능 강화를 위한 프로그램으로 고려할 가치가 있다

In this study, the BMI characteristics and food preference were examined according to the Sasang constitution typology. The constitution type of the subjects was judged by SCAT2 (SC) and Sasang specialists (SP), and the data were compared with the group (SS) in which the two results coincided. The results of SC and SP were consistent with 55 (38.2%) out of 144 subjects. Among the 55 subjects, there were 36 (65.5%), 15 (27.2%), and 4 (7.3%) Soeumin, Taeeumin, and Soyangin, respectively. The BMI of Taeeumin was significantly higher than that of Soeumin (p< .001) in all analytical methods. On the other hand, there was a difference in determining the body shape of Soyangin between the SCAT2 and specialists. The Taeeum-Soeum Food Preference Index was applied to compare the food preference to 41 types of food. In SS analysis, 13 kinds of foods preferred by Taeeumin or Soeumin were found, of which 8 (19.5%) were consistent with the existing food data. Taeeumin preferred 6 kinds of food, such as cold soybean-soup noodles, wild sesame seaweed soup, pan-fried tofu, Yeongun-jorim, Doraji-namul, and soy milk. In contrast, the favorite foods of Soeumin were black rice and Dak-galbi.

This study was conducted to investigate the antibacterial activities and sensory properties of a sauce containing tea extract and garlic vineger against raw fish. The sauce was evaluated antibacterial activity against Vibrio parahaemolyticus and Vibrio vulnificus which is considered as one of the major food borne pathogens. As a result, the sauce inhibited the growth of V. parahaemolyticus and V. vulnificus distinctly. In addition, the sauce with soy sauce and Kochujang showed the restricted growth of Vibrio parahaemolyticus and Vibrio vulnificus in sliced raw flatfish. Sensory evaluations were measured by 7-point hedonic scale using sliced raw flatfish with the sauce mixed with Kochujang and soy sauce. The score of texture in the sauce with Kochujang was significantly higher than that of regular Chokochujang (p<0.05). Moreover, total preference including appearance, texture, aroma and taste were significantly higher in the sauce with soy sauce than those of regular soy sauce (p<0.05). Consequently, the soy sauce with tea extract and garlic vinegar may enhance the satisfaction of consumer and antimicrobial activity that against V. parahaemolyticus and V. vulnificus, resulting in potential reduction the outbreaks of food borne pathogens.

This study was carried out to investigate the food value of K. pictus sprouts. The total ginsenoside content was 67.4 mg/kg. Including Ginsenoside Rg1, a total of five different types were detected by the experiment. The total phenol content was 33.77 mg/100 g. Including seven different type of essential amino acids, the total amino acid content of K. pictus sprouts was 33,744 mg/100 g. The results of the analysis of the free amino acid content showed that the total bitterness was much higher than the total sweetness. From the above results, the food characteristics of K. pictus sprouts could be determined. To improve their consumption, their bitterness must be reduced.

The food functional properties of Pleurotus eryngii cultivated with different wavelengths of light-emitting diode (LED) light were analyzed in this study. The levels of total soluble solids of Pleurotus eryngii increased with all the LED lights, except mixed LED light (B*R, B*G and R*G). Thirty one kinds of components were detected by analyzing the free amino acids. The total free amino acid contents had a slightly higher tendency in the control group, but the ratios of eight essential amino acids among the total amino acids of Pleurotus eryngii cultivated under all the LED lights, including the blue light (blue, B*R, B*G and B*R*G*U) and the green light, were higher than that in the control group. K was the highest-content of mineral, and Mn was the lowest-content. The Ca content increased through cultivation under all the LED lights, except the blue light, but the Fe content (under the green and B*R lights), K content (under the red and UV-A lights) and Mg content (under the R*G, UV-A and red lights) increased under the exclusive LED light. The total phenolic compounds increased by cultivation under all the LED lights, except the UV-A and mixed lights (R*G and B*R*G*U). The DPPH radical scavenging activity was also improved by all the LED lights, except the mixed light (R*G).

The effect of the wavelength of the light emitted by the light-emitting diode (LED) on the growth characteristics and physicochemical and sensory qualities of Pleurotus eryngii were investigated. Pleurotus eryngii were grown under different light sources: blue light (450 nm), red light (650 nm), green light (525 nm), UV-A (365 nm), and mixed light (B*R, B*G, R*G, B*R*G*UV-A). The quantity of LED light was set up at 50% (LED: 64.9-108.0 p㏖m-2·s-1;fluorescentlight:11.7lux). Fluorescent light was used as control. There were no significant differences in the flesh firmness. In the case of the Pleurotuseryngii cultivated under red, green, and mixed light (R*G), the color of the pileus and the length of the stipe were similar to those of the control group. The sensory scores were not significantly different between the LED lights (red, green, and R*G) and the control. Among the three LED light conditions, the sample cultivated under red light recorded the highest score. The samples under UV-A, blue, and mixed light (B*R, B*G, B*R*G*U) had a dark pileus color and had a short stipe. These results showed that the wavelength of LED light affected the growth and quality characteristics of Pleurotus eryngii, and that using red LED light is preferable for the cultivation of Pleurotus eryngii with better quality.

HACCP methodology was applied in the post-harvest processing and storage of domestic medicinal produces. Particularly in terms of mold and mycotoxin contamination, candidate critical control points (CCP) in the conventional practice in Korean farms were selected and monitored by comparing with on the standard guided processing and storage. When each processing of Angelicae Gigantis Radix were assessed for their safety, the drying steps such as the sun drying or the thermal drying depending on each farm made differences in mold contamination. Moreover, the storage conditions before or after the processing were another critical determinant in the fungal contamination. In other words, storage under 4˚C rather than at room temperature was favorable for reducing mold growth in the harvested crops. Occurrence rate of Aflatoxin B1 (AFB1) in Angelicae Gigantis Radix were 12.8%, but amount of AFB1 in all the collected samples were below 10 ppb regulatory limit allowed in Korea. However, for a few samples of Angelicae Gigantis Radix, still relatively high levels of total amount of the major aflatoxins (aflatoxin B1 + B2 + G1 + G2) were observed around 0.18~49.94 ppb, which is not regulated presently in Korea. It thus can be suggested that post-harvest processing and storage of Korean medicinal crops need further investigation and monitoring to establish the Good Agricultural Practice (GAP), particularly to minimize microbial risk including mold and mycotoxin contamination under the changing climate. Additionally, it is also warranted for new enacting of regulatory limits for total aflatoxins in the medicinal crops.

대량 원소의 종류 및 적정 농도의 규명은 식물의 생장뿐 아니라 유용한 2차 대사산물의 생합성량 증가를 위해 필수적이다. 참돌꽃 배양조직에서 salidroside의 생산성을 높이기 위해 기본 배지의 대량 원소의 농도를 달리하였을 때 KNO3는 98.92 mM, (NH4)2SO4는 1.01 mM, NaH2PO4·2H2O는 2.18 mM, CaCl2·2H2O는 2.04 mM, 그리고 MgSO4·7H2O는 1.01 mM 일 때, salidroside의 생산량이 가장 높았다. 또한 이와 같은 무기이온의 농도를 조합한 S4B5배지에서 기본배지인 2XB5배지에 비해 2.5배 salidroside 함량 증가를 확인할 수 있었다.
