Obesity may cause metabolic syndrome and adult diseases. This study was undertaken to investigate the ameliorative or useful effects of beanleaves on inflammation and liver damage in obese rat models. Rats were divided into three groups: a control group (normal diet, n=6), a fat diet group (45%?fat diet, n=7), and a bean leaf group (45%?fat+Korean bean leaves diet, n=7). Body weights in the bean leaf group were lower than those of the fat group (P<0.05). Serum tumor necrosis factor?α (TNF?α) and prostaglandin E₂ (PGE₂) concentrations were lower in both the control and bean leaf groups than in the fat group (P<0.001). TNF?α concentrations in the bean leaf group were slightly higher than in the control group but statistically significant (P<0.05). The bean leaf group histologically exhibited lower fatty degeneration, spotty necrosis, and leukocyte infiltrations in hepatic tissues than those of the fat group. In the homogenized liver tissues, the cyclooxygenase?2 (COX?2) gene was only expressed in the fat group. The gene expression levels of hepatic TNF?α, inducible nitric?oxide synthase, peroxiome proliferator?activated receptor?α (PPAR?α), poly (ADP?ribose) polymerase (PARP), and transforming growth factor?β1 (TGF?β1) were weaker in the bean leaf group than in the fat group. These results suggest that adding bean?leaves to the diet may ameliorate obesity?induced systemic inflammation and liver damage and that bean leaves may be a useful food for preventing obesity and thereby metabolic syndrome and adult diseases

To investigate the distribution of heavy metal concentrations in Onsan bay, concentrations of cadmium, copper, zinc and lead in surface sediments and the periwinkles (Littorina brevicula) were determined in February and July, 1996. The ranges of cadmium, copper, zinc, and lead concentrations in the surface sediments were 0.08∼3.72, 3∼307, 49∼1273 and 15∼399㎍/g dry weight, respectively. The decrease of concentration in heavy metals with distance from Daejeong stream indicated that this stream is the pollutant source of heavy metals in Onsan Bay. The concentrations of cadmium, copper, zinc and lead in L. brevicula were 0.11∼11.81, 21∼212, 30∼96 and 0.26∼4.12㎍/g dry weight in February and 1.01∼24.9, 66∼325.4, 54∼225 and 0.68∼8.41㎍/g dry weight in July, respectively. These concentrations in L. brevicula were the significantly different(p<0.001) with the season of sampling. However, overall distribution of concentrations of heavy metals in L. brevicula had very similar tendency that concentrations of heavy metal decreased with the distance from the pollutant source irrespective of the two seasons. Therefore, L.brevicula is considered as a useful indicator for heavy metals pollution. According to analysis of the organs, tissues such as the digestive gland, gill and viceral mussel accumulate high concentrations of heavy metals.

의미망 활동과 수준별 학습을 통한 영어 독해력 향상 방안 : Focusing on semantic mapping and leveled group activities

임병빈,장세숙 한국영어어문교육학회 2001 영어어문교육 Vol.7 No.1

This paper is to suggest the way to improve EFL reading skill through semantic mapping by leveled group activities. Semantic mapping is a categorical structuring of information in graphic forms or diagrams. It can be used to activate and organize background knowledge on topics in classrooms. For small group activities, the class is divided into higher leveled groups and lower leveled groups of four members based on their grades. The teaching process has three stages: Pre-reading, while-reading, and post-reading. In the pre-reading stage, students discuss what they know about the topic. They map ideas with a brainstorming technique. In the while-reading stage, they read the text about the topic. While they ar reading, they could ask some questions they might have and discuss the information in the text and categorize them with semantic mapping. In the post-reading stage, they discuss what they thought of the topic and add some information about the topic with semantic mapping. For the subjects of this study, third grade, middle school students were selected: 41 students for the experimental group and 35 students for the control group. The experimental period covered almost one semester from March to August, 2000. The results were as follows: 1) The students in the experimental group had higher scores in reading comprehension than those in the control group when semantic mapping was used; 2) The use of semantic mapping in reading comprehension was found to be much more effective in the higher leveled group than in the lower leveled group; 3) The results of questionnaires showed that many students became more interested and motivated in English, and semantic mapping helped them to participate positively in reading the English text. Thus, using semantic mapping by leveled group activities can be an effective alternative to traditional teaching methods for teachers who desire to improve reading skill in middle school students' English classes.

In this dissertation a novel speed control system that implements the fuzzy logic controller(FLC) is proposed. The proposed FLC used the speed error its rate of change, and the drive current as three fuzzy variables. The real command output current is chosen by the defuzzification of fuzzy output extracted from the fuzzy control rules. The flex and the torque of the induction motor are estimated using the dynamic model with an excellent dynamic response over a wide speed range and with the rotor flux field-oriented scheme of the decoupling characteristics The performance of this control system is substantiated by computer simulations.
