Recently, a number of scholars and educators are having a strong concern about Gardner`s theory of Multiple Intelligences and examining the capability of that theory in using as a method for organizing the teaching materials and teaching strategies related to the contents of materials. In this respect, the purpose of this study was to examine the effects of two kinds of teaching strategies using multiple intelligences as the method for organizing a lesson and a learning group. Using elementary students and subject matters, two study group were organized and received a experimental learning material. Experimental group was organized for matching and stretching MI, and took group learning activities on the base of JIGSAW Ⅱ. But comparative group was organized for only matching MI, and learned their tasks on the basis of each students` strong intelligence. The results of this study was as follows; First, According to the result of pretest-posttest analysis of Shearer s Multiple Intelligences Development Assessment Scale(MIDAS), there was significant difference in the level of MI between experimental and comparative groups. Second, like a difference in MI, there was significant difference in the score of Torrance Test of Creative Thinking(TTCT) between experimental and comparative groups. Third, the effects of MI as a teaching method could be more greater when organizing a cooperative learning group on the basis of matching and stretching MI than a simple strong intelligence group considering only the matching MI. Finally, the applying the method of matching and stretching MI simultaneously could be a efficient approach to the development of individual latent competencies and a construction of individualized instruction.

이 연구는 중학교 남학생 배드민턴 선수 20명을 대상으로 스매시 스피드와 체격요인 및 등속성 근력을 측정하여 스매시 스피드에 어떠한 요인과 관련성이 있는지 분석하고자 하는데 그 목적이 있다. 분석된 모든 자료는 SPSS Ver.22.0 프로그램을 사용하여 단순상관분석(Pearson`s simple correlation coefficient)의 피어슨 상관계수(Pearson’s correlation coefficient)를 관찰하였다. 그 결과 스매시 스피드와 체격요인 중 하지장과 흉위, 신체구성 중 신장과 골격근량은 정적상관이 나타났으나 체지방률은 부적상관이 나타났다. 스매시 스피드와 무릎관절의 등속성 근력 중 60°/sec의 부하에서 오른쪽과 왼쪽의 굴근과 신근 최대근력, 허리관절에서는 30°/sec에서 굴근 최대근력, 어깨관절은 부하속도 60°/sec에서 굴근과 신근의 최대근력에서 정적상관이 나타났다. 또한 스매시 스피드와 팔꿈치 관절의 등속성 근력 중 180°/sec에서의 신근의 최대근력과 굴근 및 신근의 평균파워, 스매시 스피드와 손목 관절의 등속성 근력은 60°/sec부하에서 굴근과 신근의 최대근력 등에서 정적상관이 나타났다. 따라서 이와 같은 결과를 토대로 중학교 배드민턴선수에게 체계적인 훈련방법을 제시한다면 스매시 스피드 향상을 위해 도움이 될 것이라 판단되고 나아가 성인 배드민턴 선수와 여성 및 동호인들의 스매시 스피드와 관련된 등속성 근력을 관찰한 후속연구가 이루어 질 수 있을 것이라 기대한다. The study aimed to conduct simple correlation analysis through the use of SPSS ver 22.0 by measuring smash speed, physique factors and isokinetic muscular strength of 20 male badminton players in a middle school. It generated the following results. As for smash speed and physique factors, limb length and bust measurement, as for body composition, height and skeletal muscle mass showed positive correlation, but body fat ratio indicated negative correlation. As for smash speed and isokinetic muscle of knee joint, the peak torque of a right flexor and angular speed at 60°/sec(load speed) and the peak torque of a right knee joint flexor and average power of a flexor and angular speed at 180°/sec showed positive correlation. As for smash speed and isokinetic muscle of hip joint, the peak torque of a flexor at 30°/sec, the peak torque of a flexor and angular speed at 60°/sec flexor, smash speed and isokinetic muscle of an elbow joint, the peak torque of a flexor and angular speed at 60°/sec, the peak torque of angular speed at 180°/sec and average power of a flexor and angular speed showed positive correlation. In addition, as for smash speed and isokinetic muscle of a wrist joint, the peak torque of a flexor and angular speed at 60°/sec indicated positive correlation.

N/A Objectives : The present study was conducted to determine whether administration of heat extracts of blori Cortex has an inhibitory effect of neutrophil-derived oxidative injury following dermal scald bum in rats. Methods : Acute lung injury was induced by scald bum (15% of TBSA) in rats. To identify acute lung edematous lung injury, 5 hrs after skin bum, protein concentrations and the number of polymorphonuclear leukocytes in bronchoalveolar lavage (BAL) were measured. In addition, levels of lung KC (neutrophil chemoattractant cytokine) and activities of lung myeloperoxidase (MPO) were measured, and morphological changes were observed. Results : Lung weight and concentration of BAL protein, the index of lung injury, were clearly increased at 5 hrs postbum compared to them of sham. Administration of heat extracts of Mori Cortex after scald burn inhibited the prtduction of KC in lung tissue and decreased the activity of lung MPO as a result of neutrophil infiltration. In histological changes, edematous lung injury with infiltration of inflammatory cells induced by skin bum were decreased by administration of heat extracts of Mori Cortex after scald bum. Conclusions : These results suggest that Mori Cortex may be a successful medical stuff in acute lung injury induced by skin bum.

This study was carried out with the aim of collecting basic data that can be applied in the manufacture of two types of canned oyster (canned boiled oyster added spicy sauce, canned roasted oyster added spicy sauce). Boiled oyster were obtained by immersing the oyster at 105℃ for 6 minutes and then washing and dehydrating them before pre-drying (40℃, 50 min). The roasted oyster were prepared by baking boiled oyster at 140℃ for 20 minutes using a smoker machine. The preparation method of canned boiled oyster added spicy sauce and canned roasted oyster added spicy sauce are as follows. Filling 50g of each boiled oyster and roasted oyster into aluminium can (RR-90) and adding 40g of mixed seasoning sauce (Mix sauce prepared by the mixing ratios of 53.85% water, 4% thick red pepper powder, 2.8% cheongyang pepper powder, 2.5% red pepper paste, 2% soybean paste, 1% oyster juice, 0.8% refined salt, 0.85% MSG, 0.2% ground pepper, 4.5% white sugar, 4.5% brown sugar, 2% sesame, 6.5% chili oil, 6.5% soy sauce, 0.5% corn starch, 0.3% xanthan gum, 7.2% mixed garlic) and then vacuumed using a double seamer under the 20 ㎝Hg of vacuum degree after preliminarily degassing at 90℃ for 3 minutes. Microbial growth test, appearance, proximate composition, pH, VBN, TBA value, amino-N, salinity, color value (L, a, b), texture, free amino acid, total amino acid, mineral and sensory evaluation were tested for the two kinds of canned products (canned boiled oyster added spicy sauce, canned roasted oyster added spicy sauce) manufactured by the condition of Fo 12 min. From the results, canned roasted oyster added spicy saucer were shown more preferable than canned boiled oyster added spicy sauce on the sensory evaluation. These results suggest that the baking process at 140℃ for 20 minutes affect the sensory preference.

LIDOCAINE과 PRILOCAINE을 혼합한 도포 마취제, EMLA크림에 대한 실험 및 임상응용

김용배,박종섭,박병일,이영만,원기정 大韓成形外科學會 1993 Archives of Plastic Surgery Vol.20 No.5

EMLA is an oil-in-water emulsion cream, containing 50mg of active substances per ml(25mg lidocaine, 25mg prilocaine). It has been shown to be effective as a topical anesthetic for painful procedure in children and adults, such as venous cannulation, removal of contagious molluscs and split skin grafting. We have tried experimental study in 20 volunteers(male : 12, female : 8) for adequate aplication time, anesthetic depth and duration. The increase in analgesic effect after removal of the cream was studied using different times(30, 60, 90, and 120minutes) for topical EMLA cream application. The pin-prick test was performed at immediately removal of the cream and 30 minutes intervals. We found the most maximal depth is 4.0±0.08mm after immediately removal of the cream at 120 minutes application times. The decreasing analgesic effect occurred gradually but, at least, acceptable analgesic effect continues during 120minutes. In clinical appliance, the operation could be completed without further local or general anesthesia for harvesting split thickness skin and dermabrasion. The two of the 20 volunteers were shown paleness on the applied area but disappeared spontaneously within 1 hour. There were no systemic side-effect. We concluded that this EMLA is very useful anesthetics for physician, especially plastic surgeon. It is very effective for superficial skin surgery, for example, split thickness skin graft, dermabrasion and electrocautery without fear and discomfort which is shown by lidocaine injection.
