The aim of this study was to evaluate the effect of incorporating wet sorghum distiller's grains (WSDG) as part of their diet on the lactating performance of dairy cows. Twenty-seven Holstein milking cows were selected, all in the early lactating stage, with an average weight of 550 kg, and producing an average of 30 kg of milk daily. The cows were divided into three groups according to milk yield and lactation and were fed different total mixed rations. The diets were formulated according to NRC (1989) recommendations in three rations to (1) control diet, (2) 15% WSDG diet and (3) 30% WSDG diet. The three different diets were all formulated as iso-nitrogen and iso-energetic diets. After one week adaptation period, the experimental feeding was conducted for 8 weeks. Three ruminal cannulated cows were also examined in order to investigate ruminal fermentation of the three total mixed rations. The results showed that the milk yield, as corrected to the 4.0% fat standard, had no significant difference among the control, 15% WSDG and 30% WSDG treatment groups (p>0.05). The daily dry matter intake of the control group was higher than the other groups (p<0.05). with respect to milk composition, milk fat, milk protein and total solids, there was no significant difference among the treatment groups (p>0.05). The energy efficiency of the 30% WSDG group were significantly higher than the other treatment groups (p<0.05). Ruminal pH value showed no difference among the treatment groups (p<0.05). Ammonia-nitrogen concentration in the control group was higher than the other treatment groups (p<0.05). The concentration of total ruminal volatile fatty acid was similar in all three dietary groups.

This study investigated anthropometric and biochemical characteristics, food and nutrient intakes, and changes in body mass index (BMI) of Korean middle age men (40~49 yrs). Data on BMI, anthropometric (height, weight, waist circumference, body mass index, blood pressure), and biochemical (total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, hemoglobin, GOT, GPT) characteristics, food and nutrients intakes, nutrient density, and index of nutrient quality were obtained from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES, 2001, 2005, 2011). Subjects were divided into three groups by year. Weight, BMI, and hemoglobin increased significantly by year. All anthropometric factors except height showed a positive relation with BMI by year. Consumption of barley, chinese noodle, confections, soybean milk, egg, ice cream, pizza, fried foods, banana, coffee, and raw rice wine increased significantly by year. Intake ratios of nutrients except water and fiber were over 100% of KDRI generally. INQ according to intakes of protein, calcium, phosphorus, iron, vitamin A, thiamine, riboflavin, and niacin per 1,000 kcal increased significantly by year. Distribution of BMI status of subjects showed a significant difference by exercise. The findings of the present study show that BMI of subjects increased by year, and intakes of all nutrients except calcium and riboflavin showed aspects of overnutrition by year. Intakes of fruits decreased while intakes of raw rice wine and coffee increased by year. Therefore, practical and systematic nutrition programs are required to maintain optimum BMI and appropriate intakes of nutrients to maintain a desirable lifestyle and improve dietary life.

본 연구에서는 사삼주를 자연 치즈에 접목시킴으로써 사삼주의 약리효과와 고유의 향미가 부여된 한국형 기능성 치즈개발을 위해 사삼주 첨가 아펜젤러 치즈(Appenzeller cheese)를 제조하여 사삼주 첨가가 치즈의 전반적인 품질 변화와 관능성에 미치는 영향을 검토하였다. 사삼주의 첨가가 숙성 중 유산균의 증식과 산 생성에 큰 영향을 미치지는 않았으나, 사삼주 6.0% 첨가구가 다소 높게 나타났고. 숙성 기간에 따라 $\alpha_{s1}$-casein의 분해가 일어나고 사삼주의 첨가량이 증가할수록 분해도가 높았으며, 숙성 촉진의 효과를 기대해 볼 수 있었다. 치즈의 총 질소 화합물(NPN, NCN, WSN)의 변화에서는 숙성 기간이 경과함에 따라 대체적으로 대조구와 첨가구 모두 증가하였다. 사삼주 첨가에 따른 분해도는 숙성 초에는 차이가 거의 없었으나, 숙성 15주에는 사삼주 첨가량이 많을수록 단백질의 분해도가 더 높은 것으로 나타났다. 사삼주 치즈의 조사포닌 함량을 측정한 결과, 4.0% 첨가구에서 비교적 높은 사포닌 회수율을 보였고, TBA 값은 숙성 초기보다 숙성 이후가 대조구보다 첨가구에서 다소 낮은 값을 보이는 것을 알 수 있었다. 소비자 기호도에서는 치즈의 향미와 맛을 제외한 외관과 조직감에서 첨가구가 다소 높은 값을 보였다. 이상의 결과를 종합하면 사삼주의 첨가가 치즈 제조상의 특성에는 큰 영향을 미치지 않았으나 첨가 수준에 따른 단백질 분해도와 일반성분의 차이를 볼 수 있었으며, 사삼주를 첨가함으로써 사포닌이 치즈 내 잔존함을 확인할 수 있었기에 이를 이용한 한국형 기능성 자연 치즈 개발이 가능할 것으로 기대되었다.

Rice alcoholic beverages, cheongju and beopju, which are recorded in "Koryodokyung", "Koryosageolyo", and "Koryosa", were used in national and royal ceremonies, and yakju was used in the Palgwanhoi ritual. In the late $11^{th}$century, King Munjong imported hwaju and haenginjabeopju from the royal family of the Song Dynasty. Alcoholic beverages in the early $12^{th}$century included the medical use for kings, such as gyehyangeoju, which the Emperor of the Song Dynasty sent to King Yejong, baekjainju, which was sent to King Myeongjong for his health, and yangju, which is goat milk fermented alcohol from the nomads in the northern regions. In the early$13^{th}$ century there was also dongrak, which is a horse-milk fermented alcohol, grape wine sent from Yuan to King Chungryeol in the late $13^{th}$ century, and sangjonju, a type of special cheongju sent from Yuan in the early $14^{th}$ century. Baekju from Yuan was recorded in oral traditions, which suggests that soju, which is distilled cheongju, was consumed in the late $14^{th}$ century. Gold and silver wares for alcoholic beverages had important political, social, and economic meanings as national gifts to other countries and internally as the king's royal gift to his subjects. In the late $14^{th}$ century, soju was prohibited, and the use of gold and silver wares for alcoholic beverages was banned at the same time. This study examined the historical characteristics of the use of traditional rice alcoholic beverages, the emotional preference for foreign alcoholic beverages, and the gold and silver wares used for alcoholic beverages Koryo Dynasty.

This review discusses the characteristics of major lignans and related studies and provides a basis for future studies. Lignans are present in various food products consumed daily, such as flaxseed and other seeds, vegetables, fruits, and beverages including coffee, tea, and wine. Lignans are natural phytoestrogens with a structure similar to that of secoisolariciresinol (Seco), mataireinol (Mat), pinoresinol (Pin), medioresinol (Med), lariciresinol (Lari), and syringaresinol, which is then converted to enterodiol (END) and enterolactone (ENL), which are mammalian lignans and the primary biologically active enterolignans, by the intestinal microflora. The associations between lignans and a decreased risk of cardiovascular disease are promising; however, they are not yet well-established, probably owing to low lignan intake in habitual Western diets. Nonetheless, these associations were more prominent at the higher doses in interventional studies. Many studies on humans and animals have reported the benefits of lignan consumption in protecting against CVD and metabolic syndrome by reducing lipid and glucose concentrations. END and ENL reportedly exert protective effects including phytoestrogenic, antioxidant, anti-inflammatory, and anticancer effects through various mechanisms. Moreover, lignans reportedly exert beneficial effects in breast, colon, and prostate cancer and osteoporosis have reported that. However, future studies are required to confirm the association between lignan and disease.

증편 반죽에서 일어나는 일련의 이화학적 성질의 변화간의 연관성과 발효시 증편 반죽의 이화학직 성질의 차이가 증편 제조 후 저장 중의 품질 변화에 미치는 영향을 연구한 결과는 요약하면 다음과 같다. 증편 반죽의 pH는 발효가 진행되면서 PH 5.96∼4:36 사이에서 계속 감소하였다. 설탕첨가군의 경우 그렇지 않은 군보다 pH 변화가 완만했으나 유의적인 차이는 없었다. 증편 반죽의 부피는 발효시간에 따라 증가했으며 발효가 반복될수록 최대 부피에 도달하는 시간이 짧아졌으며 최대 부피는 커졌다. 평균 부피는 콩물을 첨가한 군이 대조군에 비해 유의적으로 컷다(p<.05). 반죽의 점도는 발효초기에 감소하였다가 콩물 첨가군의 경우 발효 2시간 이후 급격히 증가하였으며 대조군의 경우 1차 발효 후부터 급격히 증가하였다. 반죽내의 환원당량은 설탕 총 첨가량의 1/2만 처음부터 넣은 군의 경우, 완만한 증가를 보이다가 감소하였고, 2차 발효후 다시 증가하였다. 대조군의 경우, 1차 발효시까지는 증가하였고 1차 발효 후 다시 감소하였다. 환원당량의 변화양상은 설탕 총 첨가량의 1/2만 처음부터 넣은 군과 대조군 사이에서 유의한 차이를 보였다(p < .05). 관능검사를 통한 증편의 저장시 품질의 변화를 연구한 결과 저장기간에 따라 모든 군의 경도는 증가하였고 부드러운 정도, 탄력성, 촉촉한 정도, 전체적인 수응도 등은 감소하였다. 그러나 콩물을 첨가한 군은 그렇지 않은 군보다, 또한 설탕 총 첨가량의 1/2만 처음에 첨가한 군은 그렇지 않은 군보다 이러한 변화가 서서히 일어났다. QTS로 texture를 측정한 결과 저장기간에 따라 경도, 검성, 씹힘성은 증가했으며 부착성은 감소하였다. 이러한 변화는 콩물을 첨가한 군에서그렇지 않은 군보다 서서히 일어났다.

The Nara Dynasty of Japan lasted from 710 to 784 A.D, which corresponds to the period of the Unified Shilla Kingdom of Korea. The Nara Dynasty enacted the 'Daiho Law and Ordinance' by referring to those of Tang Dynasty of China. Under these legal systems, the Ministries were defined, and foods were used for paying taxes or as currency. The characteristics of the dietary culture in Nara Dynasty were as follows. 1) They obtained food from rice and other grain farming, hunting and fishery. Rice was their main staple and was also used for preparing porridge and brewing wine. 2) Under the influence of Buddhism, meat was prohibited, and milks or dairy products were supplemented for improving malnutritional status. 3) They also used seasonings, spices and sweeteners to enhance the taste and produced medicines by extracting plants, animals and minerals. 4) While chopsticks were made of bamboo, willow, silver, shell, tree or bronze, such utensils as pan earthenware steamer, or charcoal pots were used for preparing meals. 5) Highly qualified utensils, made of porcelains painted with lacguetr, metal, glass, horn and stone, were produced as handcraft art wad developed. 6) Chinese style cousines and cooking methods were popular and various types of preserving techniques like drying or salting were used. Processed cookies were also developed. 7) Although flour was used mainly among noble class people, ordinary people also used it. The royal families ate milk products a lot and even fried foods. 8) One can say that Buddism exerted an influence on Vegetarianism from this era.

The present study attempted to determine the effect of olfactory stimulation on word retrieval deficit in Korean aphasics. Eleven nonfluent and 9 fluent aphasic patients served as subjects. The 20 subjects' age ranged from 14 to 65 with the mean of 43.0 (SD: 17.6). A neurologist examined them and diagnosed that they had no visual, auditory, and olfactory impairment. The study consisted of 2 experiments: Experiment I included visual stimulation while experiment II included visual and olfactory stimulation. The subjects were presented with 19 pictures for them to name in the experiment I, whereas they were exposed to the 19 pictures along with the corresponding olfactory stimulus in the experiment II. The 19 items included soy sauce, chilly pepper, Kimchi, chewing gum, cigarette (smoked), soybean paste, lemon, banana, alcohol (wine), apple, fish, vinegar, cuttlefish (dried), milk, rose, sesame oil, melon, coffee, and perfume. The results were as follows: First, olfactory stimulation tended to improve aphasics' word retrieval deficit although the improvement was not statistically significant. Second, the nonfluent aphasics seemed to take more advantage from olfactory stimulation compared to the fluent aphasics. Third, olfactory stimulation (olfactory + visual) did not produce a different naming performance compared to visual stimulation in the pre- and post-test when the pre- and post-test was composed of naming tasks through auditory + visual stimulation. Fourth, the fluent aphasics performed better with unpleasant olfactory stimulus while the nonfluent aphasics performed better with pleasant olfactory stimulus.
