The purpose of this study was to examine how martial-art training affected the school adjustment and sociability of teenagers in an effort to prove the effectiveness of martial-art training as part of ideal education. The subjects in this study were high school boys and girls in Gyeonggi province. After a survey was conducted, the answer sheets from 411 students were selected and analyzed by SPSS Ver. 12.0 program in a way to serve the purpose of the study. The findings of the study were as follows: First, concerning the school adjustment of the students by demographic characteristics, the boys and girls were different from each other according to their gender in relationship with teachers, learning attitude, rule abiding and school-event participation. Their gender made a significant difference to their rule abiding(P<.05), and their relationship with teacher and school-event participation varied with their gender as well. Martial-art training made a difference to their relations with peers and teachers, and they were significantly different from one another in rule abiding and school-event participation according to the type of martial art they learned(P<.01). Second, in terms of the development of sociability by demographic characteristics, their stability and autonomy differed with their gender, and their age made a difference to their stability, dominance and sociality. Their activity level, stability and dominance varied with martial-art training experience, and the type of martial art they learned made a difference to their activity level. All the differences among them were significant(P<.01). Third, as for correlation between the subvariables of martial-art training and those of school adjustment, there was a positive correlation between them. Concerning the influence of martial-art training and school adjustment, their relationship with teachers was affected by two factors that included training term and intensity. One factor, training frequency, had an impact on their peer relations, and their rule abiding was influenced by a factor, which was training term. Their school-event participation was under the influence of an element that was training term. All the impact of martial-art training was significant at the 5% level of significance. Fourth, regarding correlation between the subvariables of martial-art training and those of sociability development, a very strong positive correlation existed between them. As to the influence of martial-art training on sociability development, their activity level was affected by one factor, training frequency, and their stability was influenced by two factors that involved training intensity and frequency. A factor, training frequency, exerted an influence on their dominance, and their sociability was impacted by a factor, training intensity. A factor, training intensity, had an impact on their autonomy, and all the influence of martial-art training was significant at the 5% level of significance.

High yields of protoplasts were obtained following enzymatic digestion of the vegetative thalli of marine green alga Monostroma nitidum. The enzyme mixtures containing 4% Cellulase R-10+3% Macerozyme R-10+3% Abalone acetone powder produced 4.41×10^6 protoplasts per 300 ㎎ of fresh tissue. The highest yield of protoplasts was obtained by 270 minutes treatment of the thalli in enzyme solution. Freshly isolated protoplasts were spherical in shape and ranged between 13∼33 ㎛ in diameter. The high efficiency of differentiation were obtained by incubating freshly isolated protoplasts in 0.4 M mannitol f/2 medium for 7 days and then transferring to 0.2 M mannitol f/2 medium. Protoplasts began to form new cell walls three days after initial culture and began to germinate after 10 days, and then form a leafy thallus after further culture in f/2 medium. The addition of antibiotics in media inhibited the differentiation of protoplasts in culture.

The purpose of this study is to determine the relationship with aggressiveness and the value of sports of adolescence coming from mass media, Mixed Martial Arts Matches. The subject of the study was based on the population of Young In and Seong Nam cities and in the Gyeonggi Province, who are middle school students using Systematic Stratified Cluster Random Sampling. The participants from them in the study consisted of 336 students from questionnaires. A method of measurement was based on questionnaires, and aggressiveness was questionnaires, which was developed by Buss and Perry in 1992. Amended and supplementary questionnaires, which was developed by Evarett in 1962 were used for the value of sports. The survey used a five-points Likert scale, and then the completed questionnaires were analyzed by conducting one-way ANOVA Analysis and Multiple Regression Analysis in SPSS 12.0 program in accordance with the purpose of data analysis. The findings of the study were as follows; First, teenagers` aggressiveness from TV sports program, Mixed Martial Arts Matches was a partially considerable difference. Second, adolescence`s the value of sports is a partially considerable difference. Third, the aggressiveness have an effect on the value of sports in part.

The random amplified polymorphic DNAs (RAPD) technique was used to characterize seven isolates of the green seaweed Ulvales collected from Songjeng, Haeundae, Jumunjin, Dadaepo and Wando in Korea. Total DNA was extracted by the LiCI extraction method from thalli of green seaweed. The extracted DNA (3 ng) in 25 ㎕ reaction volume was amplified by 45 cycles of the polymerase chain reaction with arbitrary primers. Thirty-four primers resulted in 1227 PCR products ranged 240 bp to 1.5 kb of both conserved and polymorphic bands. Genetic similarities of the seven isolates calculated by Jaccard`s equation were ranged from 7% to 36%. Monostroma nitidum (Wando) was shown to be most distantly related with the others based on genetic similarity and did not produce the amplified band of 630 bp, common in Ulvales using primer OPB-01 (CATCCCCCTG).

Purpose: The preoperative assessments of the depth of invasion in the rectal wall and the presence of lymph node metastasis are very important in determining the proper treatment modality for rectal cancer. The purpose of this study is to evaluate the accuracy of transrectal ultrasonography (TRUS) for preoperatively staging rectal cancer, as compared with computerized tomography (CT). Methods: 62 patients who were diagnosed with rectal cancer were staged by using TRUS and CT, preoperatively. The ultrasnonographic tumor stage (uT), the US nodal stage (uN) and the computerized tomographic tumor stage (cT) and the CT nodal (cN) stage were investigated. The accuracy, sensitivity, specificity, PPV (Positive predictive value) and NPV (Negative predictive value) were calculated and compared with the pathologic staging. Results: The accuracies of TRUS and CT in assessing the depth of rectal wall invasion were 82.2% and 79.0%, respectively. The sensitivity, specificity, PPV and NPV of TRUS were 68.1%, 81.9%, 70.4% and 85.4% and those of CT were 53.2%, 78.9%, 73.7% and 80.7%, respectively. The sensitivity of T1 was 77.8% with using TRUS and 33.3% with using CT, respectively. The incidence of over- and under-staging was 17.8% and 9.7% with using TRUS and 25.8% and 6.5% with using CT, respectively. The accuracies of TRUS and CT in assessing the involvement of lymph nodes were 62.4% and 68.8%, respectively. The incidence of over-staging for TRUS and CT was 41.9% and 21.0%, respectively. The incidence of under-staging for TRUS and CT was 20.1% and 25.8%, respectively. There was no meaningful factor influencing the accuracy of TRUS. Conclusion: TRUS is very useful tool for the preoperative assessment of the depth of rectal cancer invasion. However, the evaluation of lymph node involvement by TRUS has limitations.
