This study aims to illustrate the value of teaching English drama in the course of teaching primary English and suggests a model for primary English drama in an English camp for Children. Drama is the world of assumption where language is used just like in real life. It has a positive effect on foreign language learning by encouraging the operation of certain psychological factors which facilitate oral communication. Dramatic techniques such as storytelling, role play, chant, song and games can be used in the EFL classroom to help bring about such results. Meanwhile, making a primary English drama in an English camp for Children would be practical mode to attain the essential purpose of EFL teaching particularly to get over the drawbacks of Korean students' communicative competence under the school's inflexible EFL education curriculum. In this paper, I will present the effectiveness of English drama and the skills for using it with ESL students and suggest some notes that can be used to reinforce the goals set out from the position of the teacher, student and teaching material. It is confirmed that the trained leader, students' affirmative attitude and systematic teaching materials are needed to maximize the effects of drama activities. In addition to that, there will be showed a model of instruction targeted to the primary students learning English in an English camp for Children.

The vertical roller mill, which performs the grinding and partly blending of raw material, is the one of the important machine to produce ordinary portland cement. It has been reported that an unexpected fatigue failure occurred in a table liner in the course of grinding portland cement. The life of table liner is estimated to $4{\times}10^7$ cycles in the design stage, but at the field, when its operating time reaches to $2{\times}10^6{\sim}8{\times}10^6$ cycles, the fracture of table liner begins to be found. The fracture of table liner is initiated from the outside edge of grinding path contacting with the grinding roller. Its maintenance normally take 30 % of the total maintenance costs of the roller mill. Therefore, this study shows the clarification of the reasons occurring the fatal destruction of the table liner by fatigue fracture analysis utilizing fracture mechanics and by the finite element method. And, the results from Goodman diagram illustrate relationship of including information on the transition between tensile and bending fatigue strength in the fatigue characterization of table liner.

Internet application for education has drawn interests in recent time. Usually the method of communication was unidirectional, which means teachers posted educational material on a server and students received them. Even the usage of WWW can't overcome the restriction of unidirectional communication problem. In order to solve this problem, researchers and commercial vendors began to provide packages for bidirectional solution. Those packages are course test generation and evaluation packages using Internet. They provide functionalities of problem generation and score management. In this paper some of those packages are reviewed, and the functionalities of JPGEM (Java Problem Generation and Evaluation Module), which is developed by the author of this paper, are discussed in detail.

This is to report a case of bronchgenic cyst. While most of the bronchogenic cysts reported in the literature so far were located either in the lung parechym or in the mediastinum near the tracheal bifurcation or main bronchi. the cyst presenting in this study was originated in the wall of the esophagus and was reported to be very rare. The cystic tumor was found accidentally by X-ray fluoroscopic examination of the esophagus and stomach in the patient with gastric hemorrhage. X-ray study revealed that the cystic tumor was oval in shape and located in the left posterolateral wall of the esophagus in the thoracic lower third. Two surgical operations, gastrectomy for gastric hemorrhage and the resection of the cystic tumor, were carried out separately. Gastrectomy including the removal of prepyloric ulcer by the Billroth II type procedure was performed in regular fashion, and the cystic tumor was resected radically without any injury of the mucous membrane of the esophagus. The cyst removed appeared to be filled with mucinous material, and histological examination identified the tumor as a bronchogenic cyst with ciliated epithelial internal lining. Postperative course of the patient was uneventful.

Objective : The incidence of head injury has been increasing in the rural area. The author investigated the clinical features and difficulties in care of the acute head-injured patients in this area. Method and Material : The authors performed a retrospective review of radiological data and clinical records in patients with mild to moderate head injury. Cause, type of craniocerebral injury, delayed intracranial lesions, complications, its relation to alcohol abuse, and outcome were analyzed. Results : In total of 68 cases, 20(29.4%) victims were associated with acute alcohol intoxication. Motor vehicle accident was the leading cause of head injury and the most common craniocerebral lesion was basilar skull fracture. Eight(11.8%) patients showed delayed radiological and clinical deterioration and 40(58.8%) were followed-up regularly after discharge. The subdural hygroma was commonly noted in the elderly and alcoholics. Causes of thirty events that resulted in an atypical and difficult neurosurgical practice were as follows : delayed admission, premature discharge against doctor's request, refusal of radiological studies and admission, misunderstanding of disease entity, and unreasonable desire of transfer to tertiary hospitals. Inaccurate initial diagnoses were made by emergency doctors in twenty patients. During the course of treatment, there were a few complications such as alcohol withdrawal, acute otitis media, cerebrospinal fistula, facial weakness, and posttraumatic seizure. Outcome was good in 60(88.2%) patients. Conclusion : Most of minor head trauma patients in this series have shown good results, but we have to consider some possible complications and delayed intracranial lesions in these patients that should be managed with special cautions with various kinds of treatment difficulties.

In case of repeated wheel-loads are acted on subbase course material, field test is generally executed to get the design standard, but the study shows dynamic properties of soils especially under repeated loads, which have not been well known to us. We try not only to obtain yield stress and elastic modulus of soil in terms of rheological model interpretation but also to investigate the influence of the repeated loads. Yield stress of soil induces hardening until approaching critical value along with the increase in number of cycle, whereas the change in modulus of elasticity with respect to the number of cycle greatly depends on the strength of repeated stress, if weak in strength of repeated stress, the modulus of elasticity increases along with the number of cycle, while if strong, it tends to decrease.
