Among ochardgrass varieties showing more than 50% callus formation ratios, the descending order of callus formation ratio after bedding the seed explants for 4 weeks was 93>Sparta>Pizza>Condor>Lidaglo>Glorus>Hapsung2>Frode. 2. The callus sizes after bedding for 4 weeks were in the range of φ 0.43cm~4.2cm in which there was 10 times size difference between the largest one and the smallest one but most of them were between φ2.5cm~4cm. 3. The regeneration ratio from callus among varieties were in the range of 0~36% and descending order of the upper 6 varieties was Plano>Akimidori>Justus>Lidacta>Currie>Hall mark. 4. The regeneration efficiency which is calculated by the ratios of regeneration from seed explant numbers was between 0 to 17.4% among which Justus showed the highest value in the 4-week treatment. 5. The correlation between callus formation ratios and the callus sizes, callus formation ratios and regeneration efficiency, and callus sizes and regeneration efficiency were r=0.5765, r=0.6365 and r=0.6246, respectively in 4-week callus and all the correlations were significant on the 1% level. 6. In 6-week callus, the descending order callus formation ratios from seed sxplants for the best 6 varieties was Condor>Sparta>93M>Justus>Potomac>Lidaglo>Frode. 7. The callus sizes formed were between φ1.5~5.7cm in which Sparta, the largest one of φ5.7cm was five times larger than the smallest one. The callus size of the control variety. Hapsung 2 was φ3.8cm, which belonged to larger size. 8. Regeneration ratio showed a great deviation among varieties from 6-week old calli by showing from 0% to 100% in which all the calli were regenerated in Plano while no callus was regenerated in Juno, 9. The range of regeneration effciency was between 0~28% among varieties in which the values from 6-week callus treatment were larger than those from 4-week callus treatment. Especially, the value of Potomac in 6-week was 3 times larger than that in 4-week. 10. The correlation between callus formation ratios and the callus sizes, callus formation ratios and regeneration efficiency, and callus sizes and regeneration effciency were r=0.8369, r=0.6683 and r=0.5937, respectively in 6-week callus, and all the correlations were significant on the 1% level.

Cooperative learning-applying group dynamics to instructional theory as a substitute for the limit of conventional teaching-learning theory-can be easily converted with other instructional model. In addition, Cooperative learning is highly recognized in combinations with music instruction by magnifying and enriching the possibility of cooperating in music class performance. This research has an object in searching cooperative-creative learning model applying cooperative learning structure to music and creative learning, and presenting concrete cooperative-creative learning technique which can assess to the level of fifth·sixth grade of elementary school. The cooperative-creative learning has following strategy and educational meanings. Firstly, making students activate and involve the practical music creative process resulting in being experience oriented learning. Secondly, deriving the creative class which fulfills the essence of music by students themselves hearing experience making, listening, sensing and telling among their mutual dependence apart from teacher's instruction. Thirdly, reflecting the idea of discovery learning finding and insighting the musical principle and concept themselves by exchanging the musical idea and information in the mutual cooperative group activity with the creating thesis. Fourthly, enlarging students' opportunity of involvement and self-expression making them experience performing and creating at the same time by directly connecting into the form of group creating. Finally, spurning and activating students' musical potential and creativity applying various cooperative-creative learning models and strategies to music class. This connects with 24 cooperative creative learning-a various and novelty. And so this research is looked forward to giving help and good effect to the scene of music class which can't activate the creative learning resulting from the lack of teacher's experience and difficulty itself through acknowledging the importance of creative learning. However the teaching strategy represented in this research connot be the standardized instruction of creating learning but can merely present one possibility in terms of teaching technique. As possibly accessing to the various methods teacher need creative effort and study by applying and reconstruct the creating activity considering many factors such as teaching ability, education conditions, student's ability, interest, and response, etc. It is important that you familiarize yourself with the creating by furnishing the opportunity of experience of creating often not just denying the creating, considering it as teachers and students' prejudice-difficult and boring class. This research-based on the principle of cooperative learning-presents the new direction to the creative learning by converting difficulty of individual oriented creative learning into cooperative learning into cooperative learning which accepts individual parts.

Objectives : To figure out the factors related to the failure of primary pulmonary tuberculosis(Tb) treatment and to enhance the efficiency of the treatment. Methods and Materials : The subjects were 137 Tb patients composed of the two groups; 44 failure cases and 93 success cases who admitted in National Masan Tuberculosis Hospital during 2001. The failure means no improvement with the standard short term regimen of INH and RFP. Patients' informations were gathered through medical records and face-to-face interview survey, and, the data were analyzed with SPSS(ver 10.0). Results : Mean age of the subjects were 47.6 years. Most cases were diagnosed at clinics or hospitals at first, due to the symptoms. No difference in smoking and alcohol habits between the two groups. The cases who got the informations about the whole process of treatment, and following regular regimens were more in the success group. The proportion of multi-drug resistance to the regular primary Tb regimen was higher in the failure group 8 cases out of 25 detectable failure cases. 0 case among 46 successful cases. And the four regular regimen(INH, RFP, EMB, PZA) was popular type of the resistance. In chest X-ray, multiply involved lesion(≥ two lobes), atelectasis and pleurisy were more frequent in the failure group. Conclusion : The major factors that enhance the efficiency of Tb treatment were the informations and compliance. Enough explanation about the whole process would be essential during Tb treatment, and, in case of MDR-Tb, susceptible regimen and surgical therapy should be considered.

Purpose: The purpose of this study was to investigate the relationships between the degree of smart phone addiction among adolescents and their depression and anxiety levels. Method: In this study, 379 high school students were selected using the convenient sampling method. The instruments used for this study were smart phone addiction measure, the CES-D (Center for Epidemiological Studies-Depression Scale), and the STAI (State-Trait Anxiety Inventory). Data were analyzed using the SPSS 20.0 program with descriptive statistics, t-test, ANOVA with Scheffe test, and Pearson’s correlation coefficient. Result: The mean score for smart phone addiction was 40.45±17.27, depression was 36.56±9.58, state anxiety was 44.00±9.61, and trait anxiety was 45.70±9.75. There were significant differences between the degree of smart phone addiction and the following variables: gender (t=-4.953, p<.001), hours of smart phone use per day (F=12.259, p<.001), types of frequently used features (F=3.485, p=.008), and satisfaction level for smart phone (F=5.18, p<.001). There were statistically significant relationships (p<.001) among degree of smart phone addiction, depression level, and state and trait anxiety levels. Conclusion: The results of this study suggested that there was a significant relationship between smart phone addiction and mental health, specifically, depression and anxiety among adolescents. Further research is needed to develop nursing strategies to provide care for adolescents who frequently utilize smart phones.

Alzheimer's disease(AD) is primarily characterized by neurofibrillary tangles, senile plaques, and neurodegeneration. The major component of senile plaques is the beta-amyloid peptide(A B), Which is considered to have a causal role in AD. However, the biological activities of AB in AD has not been clearly defined. In this study we have investigated the effects of AB 25-35 fragment to neurons using organotypic hippocampal slice culture system which maintained intact hippocampal synaptic circuit and anatomy. Hippocampal slice culture is prepared from rat pos-tnatal 10-old days and after 14 days culture, slices were treated with 10uM AB 25-35 fragment. Neuronal death was measured with propidium iodide(PI) uptake and NeuN, neuronal marker, staining. After treatment of AB 25-35 fragment for 3days or 7days on hippocampal slice culture, we observed the increased PI uptake and the decreased number of NeuN-stained neuron in CA1 region of hippocampal pyramidal layer or dentate gyrus. These results suggested that AB 25-35 fragment exerts the neurotoxicity in hippocampal slice culture.
