  • The mucosubstances in the gastrointestinal mucous secreting cells of Rana rugosa were detected histochmeically during pre-hibernating, hibernating, post-hibernating and active phases. The results of the observation were as follows: 1. The mucosubstances in the gastrointestinal mucous secreting cells of active frog were strongly PAS-active in stomach, PAS-active and alcianophilic at pH 2.5 in small intestine and alcianophilic at pH 2.5 in large intestine. 2. The PAS-active mucosubstances in the gastric surface epithelial cells were increased remarkably during hibernation. 3. The alcianophilic mucosubstances at both pH 2.5 and pH 1.0 were decreased remarkably in the goblet cells of small intestine during hibernation, but a little PAS-active ones were increased. 4. The alcianophilic mucosubstances at pH 2.5 were decreased remarkably and a lttle PAS-active ones also were done in the goblet cells of large intestine during hibernation. 5. The increases of the contained quantity of mucosubstances in the gastric surface epithelial cells during hibernationi may have theeffects of preventing cohesions of gastric mucosae and suppressing activities of gastric acid and enzymes. The mucosubstances neutral acidity in the intestine during hibernation may be secreted, because of acidity being done near neutrality in its lumen, due to remarkable decrease of intestinal juices and gastric acids.

  • The abilities of metabolic substrates, glucose, pyruvate, and acetate to produce a maximal increase in the force of contraction of substrate-depleted atria from fed rats were compared to those from starved rats, in order to observe the effect of starvation on substrate utilization of the myocardium. Starvation results in a marked loss of body weight in rats. In contrast to the starved rats, the body weight of fed rats increased with time. When placed in substrate-free medium, atria from fed rats showed marked decline in contractile force. In contrast to the atria from fed rats, the substrate-depleted atria from starved rats showed much less decline of the force of contraction. In the substrate-free medium, abilities of glucose, pyruvate, and acetate to produce a maximal increase in the force of contraction of atria from fed rats were much greater than those from starved rats. The data from these studies indicate that in the substrate-free medium atria from starved rats utilize much less exogenous substrates than those from fed rats. These results suggest that starvation has no deleterious effect on contractile activity of the myocardium, and the starvation increase the storage of readily metabolizable endogenous substrstes useful for the functional activity of the isolated heart.

  • This study investigated the influence of consumers' self-construal and self-monitoring on brand product preference by moderating brand visibility. Brand visibility consisted of product typicality and brand salience. The study results showed that respondents preferred products with high product typicality and low brand salience. Respondents with interdependent self-construal and high self-monitoring also showed a higher preference for high product typicality and low brand salience versus respondents with independent self-construal and low self-monitoring. Respondents preferred a product when they recognized a brand name, but brand visibility should be exposed naturally. Based on these results, this study has practical implications for the importance of maintaining brand identity and the appropriacy of brand logo size.

  • 무, 당근 및 감자를 대상으로 조리방법 (boiling, pressure cooking, microwave cooking)에 따른 dietary fiber 성분, 수분함량 및 조직감의 변화에 대하여 조사하였으며 조직감에 영향을 미치는 성분에 대해 연구해보았다. 시료내에 존재하는 pectin의 함량은 조리시 원료시료에 비해 현저하게 감소하였으며, microwave cooking>pressure cooking>boiling의 순서로 점차 감소하였다(P<0.05). ADF, NDF 및 Cellulose, Hemicellulose, Lignin은 boiling과 pressure cooking의 경우에는 원료시료에 비해 모든 성분이 증가현상을 나타내었으며, microwave cooking의 경우에는 감소하였다(P<0.01). Hemicellulose와 lignin은 조리에 의한 영향을 거의 받지 않는 것으로 나타났으며, cellulose는 조리 방법에 따라 상당한 영향을 받는 것으로 나타났다. 조리방법에 따른 수분함량의 변화는, boiling시에는 원료시료에 비해 현저한 증가를 보였으며, pressure cooking의 경우에는 조금 감소하였으나 뚜렷한 차이가 없었고, microwave cooking시에는 현저한 감소현상을 나타내었다(P<0.001). 조리 방법에 따른 조직감의 변화는 침투시험시에는 maximum force가 raw>microwave cooking>pressure cooking>boiling의 순서로 점차 감소하였으며, 절단 시험시에는 maximum force가 microwave cooking>pressure cooking>raw>boiling의 순서로 점차 감소하였다. 관능검사 결과, 견고성은 원료시료가 가장 컸으며, microwave cooking>pressure cooking>boiling한 시료의 순서로 점차 감소하였고 씹힘성은 microwave cooking방법으로 조리한 시료가 가장 컸으며, pressure cooking>raw>boiling의 순서로 점차 감소하였다. 기계적 측정 결과와 관능검사 결과를 연관시킨 결과, 높은 연관성이 있었다. 이러한 결과로부터 조리시 시료의 견고성은 pectin의 함량과 밀접한 관계가 있어서, 즉 pectin의 함량이 증가함에 따라 견고성이 증가되는 것을 알 수 있었고, 씹힘성은 수분함량과 밀접한 관련이 있어서, 즉 수분함량이 감소함에 따라 씹힘성이 증가되는 것을 알 수 있다. 이상과 같은 결과들은 무, 당근 및 감자에 있어서 모두 같은 경향을 나타내었다.

  • This study explores of press report on the death of Beongen Yoo based on network analysis and how issue diffuses via Internet and SNS in mainstream news and conservative channels of comprehensive programming. Issue salience, word's visibility and word's connectivity are the main keyword and analysis criteria of this study. Conservative channel of comprehensive programming focused on the surrounding information rather than core information compared to Mainstream media, Conservative channels of comprehensive media was interested in Yu, Beongeon, an article left, brand, rumor of a body and Mainstream media focused on the results of DNA test. Mainstream media covers this case as the discovery of the Yu, Beongeon body, Mainstream media reported as 'the discovery of the body frame, conservative channels of comprehensive programming reports as blame of investigation at the first stage. The former focuses on the cause of death and the latter focuses on the raising of strong doubts frame at the second stage. In case of the third stage the latter covered on the emphasis of the surrounding information. They frames the issue differently based on network analysis. The view point of conservative channel of comprehensive programming is diffused via SNS. This study highlights the role of journalist of mainstream media in the process of agenda-setting

  • The term underground stem is not used correctly as mesocotyle that is the first internode of barley, wheat and rye. Mesocotyle does not elongate and it remain in the seed in case of these crops. The elongated stem is second internode of these crops and not mesocotyle but rhizome or underground stem. The node on which the underground stem is attached is coleoptile node and coleptile is attached here. The objective of this study was to determine if the depth of sowing affect the coleoptile length and plant height. The deeper sowing caused the longer coleoptile length and plant height. Coleoptile length and plant height of 2cm depth of sowing showed significant difference with 6cm and 10cm depth of sowing in barley and wheat. Variation of these two characters were high in rye and corn because these crops were both heterogeneous due to out crossing. All the varieties of 4 crops showed significant correlation between coleoptile length and plant height. Chilbohomil showed highly significant correlation between two characters.

  • The purpose of this study was to determine the possible additive effects of endurance exercise training (EXER) and selenium (SELE) on the improvements of glucose and lactate transport capacities in diabetic Goto-kakizaki rats. Animals either remained sedentary control (SED) or performed EXER or received SELE [$5{\mu}mol$ kg body wt (-1) day (-1)], or underwent both EXER and SELE (COMBI), which lasted for 6 wk. Compared with sedentary control, EXER alone or the SELE alone group, or the combined treatment group had significant reduction in glucose response measured at 90 min and 120 min during an intraperitoneal glucose tolerance test (IPGTT) and body weight after 6week treatment. EXER alone, or combined group individually had significantly higher glycogen contents in liver compared with SED or SELE groups. EXER alone increased glycogen content in soleus and plantaris compared with SED, and this parameter was increased to greatest extent in the combined treatment groups compared with SED or SELE groups. EXER alone, SELE alone or COMBI, caused significant decreases in the plasma lactates, serum glucose, insulin, total cholesterol and HOMA-IR along with a significant increase in high-density lipoprotein cholesterol compared with SED. In addition, EXER or COMBI individually had significantly lower serum triacylglycerol compared with SED or SELE. With respect to protein expression related to glucose and lactate transport capacities, EXER alone, SELE alone, or COMBI increased in MCT1 and MCT4 protein level in soleus and plantaris. Furthermore, EXER alone, SELE alone or COMBI caused significant increases in mt MCT1 protein level in soleus and plantaris. The findings of the current study suggest that endurance exercise training and selenium treatment may provide therapeutic values to type II diabetic patients with peripheral insulin resistance and hyperlactatecemia by improving glucose and lactate transport capacities, leading to improvements in plasma lactate, serum glucose, insulin and lipid profiles (TC, TG, HDL).

  • This experiment was conducted to identify the superior corn hybrids for silage production and to determine the combining ability of their parental inbred lines. A 7-entry diallel cross was evaluated for grain and stover yields, and agronomic characters under 3 different seasons. Hybrids Hi34 x Tx601, Hi26 x Hi34, and Hi29 x Hi34 showed high total dry matter yields. In general, late maturing hybrids had higher grain and silage yields than early maturing hybrids. Leaf area index was correlated with grain and stover yields. Rust rating was negatively correlated with yields and all characters, indicating that rust (Puccinia sorghi) was one of the major factors affecting yields. Diallel analysis showed that inbred Hi34 which was late in maturity and resistant to rust was the best combiner for both grain and silage yields. General combining ability (GCA) and specific com-bining ability (SCA) effects for yields and other characters were significant, suggesting that both additive and non-additive gene effects are involved for those characters. Ratio of GCA/SCA mean squares showed that GCA effects were more important than SCA effects for yields and other characters. GCA x season and SCA x season interactions were significant for grain and stover yields, revealing that gene effects were not stable for those yields under dissimilar environments.
