  • It has long been shown that Korean EFL students have not practiced extensive reading in school curriculum. Their vocabulary knowledge is limited and a tool for measuring text readability for them has hardly been developed and used. The study aimed to check the current situations on the above issues and develop a reading framework appropriate for extensive reading within the national English curriculum, including the Readability Formula in Korean EFL contexts (KRF). The study consists of four steps. The study does a survey to check the current Korean EFL situations on the issues, suggests a new vocabulary learning size, develops a readability formula as a tool for measuring text difficulty based on the newly suggested vocabulary size, and finally validates the formula with various kinds of English books, including the primary and secondary school English textbooks. It is expected that this study will provide a model for the vocabulary size and the readability index for extensive reading in EFL contexts.

  • In this paper, mechanical property of electric epoxy with water aging was discussed. We studied mechanical property of elastic resin after absorption in water from 0 to 484 hour. As a result, diffusion factor of elastic epoxy showed $20-21{\times}10^{-4}mm^2/s$ and general epoxy showed $9.5{\times}10^{-4}mm^2/s$. Elastic property increased linearly according to amount of addictives and decreased elastic property according to amount of water absorption. Tensile strength was reduced to add to addictives. It was effected by water absorption of micro-void of elastic epoxy. Hardness inclined to decrease after increasing according to absorbed time.

  • The brachial plexus is a network of nerves that provides movement and feeling to the shoulder, arm and hand. The majority of acute brachial plexus injuries occur when the plexus is stretched violently or torn. This happens as result of the shoulder being pressed down forcefully while the head is pushed up and away from that shoulder. Such injuries frequently result from automobile or motor-cycle accidents or from falls and usually affect one side. Nerve injuries vary in severity from a mild stretching of the nerve to a tearing of the nerve root away from the spinal cord. We experienced a 50-year-old woman with weakness in both upper extremities after an attempted hanging. A consecutive workup revealed bilateral brachial plexus injuries. Six months after the incident, she had fully recovered. This is a very rare case of bilateral brachial plexus injuries after an attempted hanging.

  • In this paper distributed models for simulating spatially and temporally varied moving storm in a watershed were developed. The complete simulation in a watershed is achieved through two sequential flow simulations which are overland flow simulation and channel network flow simulation. Two dimensional continuity equation and momentum equation of kinematic approximation were used in the overland flow simulation. On the other hand, in the channel network simulation two types of governing equations which are one dimensional continuity and momentum equations between two adjacent sections in a channel, and continuity and energy equations at a channel junction were applied. The finite difference formulations were used in the channel network model. Macks Creek Experimental Watershed in Idaho, USA was selected as a target watershed and the moving storm on August 23, 1965, which continued from 3:30 P.M. to 5:30 P.M., was utilized. The rainfall intensity fo the moving storm in the watershed was temporally varied and the storm was continuously moved from one place to the other place in a watershed. Furthermore, runoff parameters, which are soil types, vegetation coverages, overland plane slopes, channel bed slopes and so on, are spatially varied. The good agreement between the hydrograph simulated using distributed models and the hydrograph observed by ARS are Shown. Also, the conservations of mass between upstreams and downstreams at channel junctions are well indicated and the wpatial and temporal vaiability in a watershed is well simulated using suggested distributed models.

  • This study was designed to evaluate antihyperglycemic and antihyperlipidemic effects of ethanol extracts of Taraxacum mongolicum(T.m.) on streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley rats were randomly assigned to five groups: normal (NC), STZ-control (DC), and three experimental groups. Diabetes was induced in Sprague-Dawley rats with a single intravenous injection [45 mg/kg body weight (b.w.)] of STZ. An ethanol extract of T.m. was orally given to diabetic rats for 14 days. Three experimental groups were additionally treated with T.m. extract at doses of 1 g/kg b.w./day for T.m.-1, 2 g/kg b.w./day for T.m.-2, and 3 g/kg b.w./day for T.m.-3. Oral administration of T.m.-2 significantly increased their body weights. T.m.-1 and T.m.-2 significantly decreased aspartate aminotransferase (AST) levels than DC. T.m.-1 and T.m.-2 group significantly decreased blood glucose levels. Total cholesterol, triglycerides, and free fatty acids were significantly decreased whereas high-density lipoprotein cholesterol was significantly increased in groups treated with T.m. extract than those in the DC group. These results support the fact that administration of T.m. extract can reduce hyperglycemia and hyperlipidemia risk in diabetic rats.

  • Purpose: The aim of study was to investigate relationship between compliance and recovery of patients with osteoarthritis of the knee patients after knee arthroplasty. Methods: 193 patients living in Seoul were participated in this study. Data were collected using the Knee Society Clinical Rating System and Medical Outcomes Study Short Form 36(SF-36) and analyzed by ANCOVA, t-test, and repeated measure ANOVA. Results: There was a significant difference of physiological recovery based on the number of co-morbidity patients have. Physical recovery level was different according to age, religion, and the number of co-morbidity. Age and education level of patients were different in emotional recovery. The level of physiological and physical recovery were significantly different consistent with compliance. Compared to preoperative scores, physiological and physical scores showed significant improvement at six weeks, three months, and six months after surgery while emotional scores did not showed significant improvement. Conclusion: The results of this study suggest that nursing interventions to increase compliance are needed for better recovery of patients after knee arthroplasty.

  • An ecological study of food and nutrition was conducted among 198 children, 6 to 12 years old, of the Songmyun elementary school and Samsong elementary school, located in remote villages of Chungchun-myun, Goisan-gun, Chung Buk Province between July 11 and 16, 1988. The results were summarized as follows. In regard to frequency of skipping breakfast, 3.3% of subjects skipped every morning; 15% often skipped; and the others never skipped. The most common reason for skipping a meal was lack of appetite. 6.6% of subjects often skipped an evening meal because of delayed meal preparation by a mother who returned home late. The survey found that 5.1% of subjects skipped a lunch at school. The reasons for skipping lunch were the mother’s being too busy to prepare a boxed lunch; a school bag too heavy to carry for a long distance to school; no adequate side-dishes for the boxed lunch. Growth patterns of those children having poor food habits, were reflected in lower figures in arm circumference and weight for height. The percentage of children having meals with their family on weekdays was 84.7% for breakfast; 85.6% for evening meal. About 7% of subjects had many dislikes and 74.1% had some dislikes in what they ate; 18.9% had good food preferences. There was a strong correlation between appetite or food preferences and anthropometric measurements or nutrient intake. Boiled rice was the predominant dietary staple, and principal sources of protein taken by subjects at home were soy beans and soy products. Regarding the boxed lunch prepared at home, most popular was one with only one kind of side-dish, including kimchee. 43.4% of the side-dishes were prepared with vegetables only. As for between meal snacks, milk and milk products, fruits and breads were popular among the subjects. The survey found that the children liked fruits, yogurt, corn, Chajang noodle; in contrast, lowest preference was for soup made with bones, curried meat with rice, and aromatic vegetables. The survey discovered a local dietary characteristics; 46.2% of the children customarily ate frog meat, an unconventional food.

  • In this study, in order to evaluate the 4th local government heads and to grope for ways for development of the government, the researcher surveyed public officials in Daejeon, Chungnam and Chungbuk regions. The main contents of the survey were such as the leadership type and characteristics of the local government heads, their administrative characteristics, and evaluation of their pubic pledges. And for the surveyed questionnaires, the researcher did cross-tabulation and analysis of variance using the SPSS 12.0 statistics program. As the result of the analysis, on the basis of most indexes, the provincial governor of Chungcheongnam-do was found to have received more affirmative support than those of Chungcheongbuk-do and Daejeon Metropolitan City. Therefore, it seems that provincial governor of Chungbuk and mayor of Daejeon Metropolitan City need to benchmark the leadership of the provincial governor of Chungnam.
