This study was conducted to analyze the contents in the dietary fiber and amino acid compositions of 23 vegetables and 6 fruits and to identify the current contents. We generated data on the contents of total, insoluble and soluble dietary fiber (TDF, IDF and SDF), respectively. The TDF and IDF contents were lowest (0.56 g/100 g and 0.44 g/100 g) in wild garlic and highest (5.87 g/100 g and 5.66 g/100 g) in perilla leaves. A total of 18 kinds of amino acids were found in most samples. Essential and non-essential amino acid contents ranged from 53.16-2107.54 mg/100 g and 191.66-2892.28 mg/100 g, respectively. The highest essential and non-essential amino acid content was hot pepper leaves followed by perilla leaves and aralia. They had higher contents of both TDF and amino acids. The results of the study can serve as a fundamental source of information in DF and amino acids for diet planning.

This study was conducted to investigate the effect of CA(4% O2 and 7.5% CO2) storage on the quality characteristics and chilling injury in ``Nanko`` prunus mume fruits at 1, 5, and 9℃. CA storage reduced production of CO2 and C2H4 significantly. Hue values of fruit skin were significantly higher in fruits stored at 1℃ and 5℃ than 9℃. Weight loss was much lower in fruits stored under CA storage. Soluble solids content (SSC) titratable acids (TA), and firmness were maintained and electrolyte leakage was lower in fruits stored under CA storage. Ratios of chilling injury and decay were increased faster at 5℃ and 9℃ than 1℃. The chilling injury was suppressed in fruits of CA storage compared with control fruits during cold storage. These results indicate that CA storage at 1℃ of prunus mume fruits extended the storage life up to 30 days without quality deterioration, effectively.

머루 과피 용매추출물의 전자공여 작용, 환원력, SOD 유사활성, TBARS 및 아질산염 소거작용을 측정하여 항산화 기능을 규명하고자 하였다. 총 페놀과 플라보노이드 함량이 가장 높은 ethyl acetate 추출물의 경우 전자공여 작용도 100㎍/mL 농도에서 79.2±0.06%로 BHT(74.1±0.15%)보다 더 활성이 높았고, 추출물의 농도에 비례하여 전자공여 작용과 환원력은 유의적으로 증가하였다. SOD 유사활성은 100 ㎍/mL 농도에서 ethyl acetate와 butanol 추출물에서 각각 25.1±0.41%와 20.2±0.13%로 다른 추출물에 비해 높은 활성을 보였다. FeCl2와 CuSO4에 대한 항산화 활성도 추출물의 농도가 높아짐에 따라 그 활성이 증가하는 경향이었는데, ethyl acetate 추출물은 ascorbic acid보다 항산화 활성이 높았다. 머루 과피 용매추출물의 아질산염 소거작용은 pH 2.5에서 ethyl acetate(90.5±0.75%)>butanol(65.9±2.16%)>hexane(58.1±1.74%)>chloroform(55.4±1.02%)>water(40.9±0.35%) 추출물의 순으로 소거작용이 높았다. 이상의 결과를 종합하여 볼 때 머루 과피의 항산화 활성은 ethyl acetate 추출물에서 가장 우수하였다. This study was worked out to investigate antioxidant activity of solvent extracts from wild grape skin by measuring electron donating ability (EDA), reducing power, superoxide dismutase (SOD)-like activity, thiobarbituric acid reactive substances (TBARS) and nitrite scavenging ability. Total phenolic compound and flavonoids contents were the highest in ethyl acetate extract, 54.4±1.18 ㎎/100 g and 645.1±5.05 ㎎/100 g, respectively. The EDA and reducing power of solvent extracts from wild grape skin were proportionally increased with concentration and ethyl acetate extract (79.2±0.06%) showed the stronger than BHT (74.1±0.15%) at concentration of 100 ㎍/mL, especially. SOD-like ability of ethyl acetate (25.1±0.41%) and butanol (20.2±0.13%) extracts were stronger than other extracts at concentration of 100 ㎍/mL. TBARS of ethyl acetate extract was higher than ascorbic acid. Nitrite scavenging ability of solvent extracts from wild grape skin (pH 2.5, 1,000 ㎍/mL) were in order of ethyl acetate (90.5±0.75%)>butanol (65.9±2.16%)>hexane (58.1±1.74%)>chloroform (55.4±1.02%)>water (40.9±0.35%). Antioxidant activity of solvent extracts from wild grape skin was the highest in ethyl acetate extract from the results of our experiments.

본 연구는 최근 소비가 증가하고 있는 세척사과에 대한 농약 및 미생물 안전성에 대한 효과적인 세척방법의 기초자료를 얻고자 수행되었다. ‘후지’ 사과를 사용하여 1차 세척을 거친 후 수돗물, 염소수, 전해수, 오존수, 초산용액 등의 세척을 실시하였다. 세척수의 미생물 제어 효과는 전해수, 염소수, 오존수, 등에서 효과적이었으며 특히 전해수와 염소수의 경우 다른 처리구에 비해 가장 높은 살균 효과를 나타내었다. 잔류농약의 경우 농약 성분에 따라 효과의 차이는 있었으나 염소수, 전해수, 초산 등의 용액 세척이 수돗물 세척보다 잔류농약 감소에 효과적이었다. 전해수 세척으로 myclobutanil 성분을 0.39㎎ㆍℓ⁻¹에서 0.10㎎ㆍℓ⁻¹으로 낮추어 74.4%의 제거율을 보였다 각각의 세척수에 세척한 후 미생물과 품질 변화를 비교하였을 때 수돗물 세척과 초산용액 세척은 미생물 개체수가 오히려 증가하거나 감소 효과가 없었으나, 전해수, 염소수, 오존수 등 세척의 경우 세척 직후에 미생물 개체수를 현저히 감소시켰다. 또한, 염소수와 전해수 100㎎ㆍℓ⁻¹ 세척 사과는 0℃ 저장시 2주 동안 총균수 억제능이 우수하였다. 세척에 따른 품질특성을 조사한 결과 세척 전ㆍ후 중량감소율, 색도, 경도, 당도, 산도 등의 이화학적 특성은 세척방법에 따른 차이를 보이지 않았으며, 세척처리가 저장성에 미치는 영향 또한 없는 것으로 판단되었다. 따라서, 사과의 잔류농약 및 미생물 제어에 있어서 전해수와 염소수를 이용한 세척과정이 사과의 품질변화 없이 안전성을 위한 효과적인 전처리 방법으로 생각되었다. The study was conducted to investigate the efficiency of different washing treatments which can remove pesticides and microorganism contaminations on apples (Malus domestica). Apples were washed with tap water, chlorinated water, electrolyzed water, ozonated water, and acetic acid solution, respectively as prestorage treatment and then changes in pesticide residue and microorganism activity were estimated. Although there were differences in effect according to the type of the pesticide, washing treatments were more effective than tap water treatments in pesticide removal. Especially, residues of myclobutanil was decreased from 0.39 to 0.10 ㎎ㆍℓ⁻¹ after electrolyzed water treatment (removal rate 74.4%). Population levels of total microorganism were also reduced by chlorinated, electrolyzed and ozonated water, but increased or not affected by acetic acid solution and tap water washings. Chlorinated and electrolyzed (100 ㎎ㆍℓ⁻¹) water treatments were markedly reduced populations of total microorganism for 2 weeks at 0℃. The effect of water treatments on quality attributes during storage at 0℃ was not significantly different from other water treatments. As a result, if pesticide and microbial reduction, and maintaining quality are taken into account together, the cleaning process using chlorinated and electrolyzed water were the most effective washing treatment methods.

In order to retrofit the seismic and wind performance of the traditional wooden buildings, it is essential to evaluate the structural performance of them. However, limited researches on the evaluation of the dynamic characteristics and structural performance based on in-situ vibration measurement have been performed, and the systematic in-situ vibration measurement method is not established for traditional wooden buildings unlike the those for RC and steel buildings. In this paper, an in-situ measuring method is introduced for traditional wooden buildings based on the assumption that the rigid diaphragm action is applicable since roof and rafter restraints the rotation of columns similar to slabs in RC and steel buildings. The proposed method is applied to the dynamic characteristics identification of a small traditional wooden building and its applicability is evaluated. Finally, the method is also applied to the in-situ vibration measurement of eight traditional wooden buildings which are designated as national treasures.

This study was conducted to evaluate the quality characteristics of and chilling injury development in ‘Ooishiwase’ plum fruits after harvest, according to the ripening stage and storage temperature. The fruits were harvested at three ripening stages (60, 80, and >90% skin color) and were then stored at 1, 4, 5, 6, and 20℃ cold-storage rooms for up to 48 days. The fruit quality parameters, respiration patterns, and chilling injury development were monitored during the storage periods and the three days of subsequent ripening at 20℃. The fruits harvested at the 60%-skin-color stage maintained the flesh firmness, color, weight loss, and TA, and their respiration rates and ethylene production were decreased compared with the 80%- or >90%-skin-color fruits, at a lower storage temperature. The major symptoms of chilling injuries in the Ooishiwase plums were gel breakdown, flesh browning, and flesh translucency. These symptoms appeared at all the low-storage-temperature and ripening treatment stages. When the fruits, however, were harvested at a more immature stage and were stored at a lower storage temperature, the chilling injury development decreased. These results show that the development of chilling injury in Ooishiwase plums is related to the climacteric behavior during cold storage.

당뇨병 환자의 혈당조절 식이를 개발할 목적으로 탈지시킨 곡물류 분말(대두 40%, 밀가루 30%, 보리 20%)과 홍삼분말 5% 및 밀가루 5%로 혼합한 바이오활성(BP)분말을 전체식이의 중량비로 40% 투여가 streptozotocin으로 유발한 당뇨쥐의 혈당강하 효과와 체내지질의 농도에 미치는 영향을 조사하기 위하여 SD계 웅성 흰쥐를 정상대조군, 당뇨대조군, BP분말 식이 당뇨군, 밀가루 식이 당뇨군 및 쌀가루 식이 당뇨군으로 나누어 5주간 급여하여 식이실험을 행하였다. 식이효율은 당뇨 대조군에 비하여 모든 실험군에서 증가하였으며, BP 분말군은 당뇨대조군에 비하여 5주간 식이 섭취에 따른 체중증가(75.1 vs. 29.3 g)와 혈당강하(270.1 vs. 541.7㎎/dL) 효과가 각각 유의적으로 차이가 나타났다(p<0.05). 혈장 총콜레스테롤의 함량은 BP 분말군이 당뇨대조군에 비해 유의적으로 낮게 나타났으나(p<0.05), 다른 당뇨 식이군과는 차이가 없었다. 간에서 총콜레스테롤 및 중성지질의 함량은 BP 분말군이 정상대조군을 제외한 모든 당뇨 식이군에서 가장 낮은 수준을 나타내었다. 결론적으로 BP 분말을 흰쥐의 식이에 첨가하여 섭취시키면 혈당강하 효과와 체내 지질대사를 개선하는 효과를 나타내었다. This study was conducted to examine the effects of feeding diets containing bioorganic power (BP) flour, wheat flour and rice flour on blood glucose and lipid level in streptozotocin-induced diabetic rats. BP flour was composed with the mixture of defatted flour (16 g soybean, 12 g wheat, 8 g barley), 2 g red ginseng and 2 g whole wheat flour per 100 g diet. Experimental groups were divided into non-diabetic normal and 4 diabetic groups containing control, 40% BP, 41.6% wheat and 41.6% rice flours with basal diet. BP group was significantly increased body weight gain and decreased plasma glucose compared with the diabetic control, wheat and rice flour groups (p<0.05). Food efficiency ratio of diabetic rats were significantly lower than that of the normal rats. The concentrations of total cholesterol and triglyceride in plasma and atherogenic index were significantly decreased in BP, wheat and rice diabetic groups than diabetic control (p<0.05). The concentration of total cholesterol and triglyceride in liver was significantly lower in BP group as compared with the diabetic control, wheat and rice flour groups (p<0.05). In conclusion, the results indicated that BP flour feeding improved plasma glucose level, total cholesterol and triglyceride in diabetic rats.
