There is no progress in interpreting the correlation between the high school record and the scholastic aptitude test. This study gives the degree of the linearity between the high school record and the scholastic aptitude test by using the method of the individual scholastic evaluation which was proposed by Chung(1999). The limits of the individual scholastic evaluation are pointed out additionally in inferring the promising individuals having the high scores in the scholastic aptitude test so that the individual scholastic evaluation be used as reference materials when the colleges applying the comparative school record in the entrance exams.

This study aims at solving the problem in the application method of the comparative school record which is currently being discussed in depth among colleges. The application method of Kay O. Lee and Yeon Soo Cung(1997) which was appied in the 1999 Korean air force Academy Admission Process was found to be problematic in the following respects. First the setting of the standard which divides all the high schools in kora into five groups relative to their scholastic level is somewhat vague and subjective secondly the difference among those levels which resulted from the five grouping could greatly influence on the admission of the applicants and thirdly there is no standard in choosing those few promising individuals with high scholastic aptitude test results from the low level groups such as level four and five,. Therefore this study suggests and introduces a nationwide individual scholastic evaluation that would complement the limits and problems in the application method of the comparative school record.

This study in order to seek for a more effective teaching method, I am to propose a measure that the career education material for female middle school students a program produced already could be applicable on the class and to understand the efficiency by examining practically it to the student. The research method was to make up a questionnaire and gaze two kinds of educational effect. The procedure was that, after surveying the general features in order to help them known their consciousness on the career education Researcher practiced common theorectical teaching on comparative class and moduling teaching on comparative class through making a guiding data. Then Researcher analysed the changing o consciousness on career, knowledge on kinds and numbers of jobs, and the results and rate of interest in the teaching with persentage and t-test. The results are as followed; First, on the consciousness on career, both group showed little change on their wishful job between before and after teaching. On the purpose to get a job, consciousness on work and job, and fixed idea of job on gender, there were some changes, but both groups had few defferences in the changing rate. Second on the consciousness on work and job experimental group recognized the variety of job more than comparative group and wrote more hind of job. Third on the evaluating result, the record of experimental group was higher. Fourth, on the rate of interesting in learning the rate of experimental group was higher. As observed the class applied by the module of female career education is effective, since experimental group showed more consciousness on work and job, evaluation of record after teaching and the rat of interesting in learning, through there was no difference in the consciousness of the career.

Purpose: The aim of this study was to identify the contraceptive knowledge, self-efficacy according to the career tract of high school female students. Methods: This study used a cross-sectional, correlational design using an exploratory survey methodology through self-reported questionnaires. The questionnaires were administered to 369 high school female students using a convenience sampling. Results: In the experience of sexual behaviors(grasping hand, hugging, petting, deep petting, sexual intercourse), technical female high school students showed more experiences than female high school students. In the contraceptive knowledge, the score of high school students' contraceptive knowledge was higher than technical female high school students. In the contraceptive self-efficacy, there was not a significant difference between the technical female high school students and female high school students. In the female high school students, there were significant differences in the contraceptive knowledge according to grade, academic record, sex education experience and there were significant differences in the contraceptive self-efficacy according to grade, academic record, parents' attitude about acquaintance of the opposite sex. In the technical female high school students, there was not significant difference in the contraceptive knowledge according to demographic, sexual behavior, and contraceptive related characteristics but there were significant differences in the contraceptive self-efficacy according to grade, parents' attitude about acquaintance of the opposite sex, contraceptive education experience at school. There was positive relationship between contraceptive knowledge and contraceptive self-efficacy. Conclusion: Further research is needed to identify the prevalence rate of contraceptive attitude using more reliable variables. A sex education program should be developed for promoting use of contraceptive measure and formation of positive contraceptive attitude among high school female students.

Oncholaimid nematode, Oncholaimus secundicollis Shimada, Kajihara and Mawatari, 2009, is firstly reported based on a comparative morphological study. The present specimens of O. secundicollis are collected from rocky intertidal seagrass on the eastern coast of Korea. Oncholaimus secundicollis is distinguished from all of its congeners by the following combination of morphological characteristics: buccal cavity large with thick cuticular wall and three teeth, left subventral tooth larger than right subventral or dorsal teeth, and the presence of two remarkable precloacal papillae with nine pairs of cloacal setae and single ventral tail papilla with two pairs of short setae. In this study, we provide taxonomic description and illustration of unrecorded species of the genus Oncholaimus.

The genus Peloribates is comparatively species rich and distributed worldwide. More than 90 species have been assigned to this genus, but three species were reported in Korea. We recovered a new species, Peloribates barbatus Aoki, 1977 to Korean inventory in the family Haplozetidae (Acari: Oribatida) from the straw mat covering the cherry trees. This species was originally reported as inhabiting in lichens growing on tombstones in Japan. In this paper, we present a comparative account of morphological description of the species with other three congeneric species in Korea.

The purpose of this thesis is that the students understand the sentence stated math problems closely related to the real life and adapted the right solving strategies try to find the solution to a problem. The following research problem were proposed. 1. How repeated thinking lessons develop the understanding of problems and influence the usage of correct problem solving strategies and extensions of problem solving. 2. There are how much differences of achievement for each type of sentence stated problems by using comparative analysis of upper class, intermediate class, and lower class for each level between the experimental and comparative classes. In order to conduct this research the classes were divided into three different level - upper class, intermediate class and lower class. Each level include an experimental class and a comparative class. The two classes (experimental class and comparative class) of the same level were tested on the basis of class division record with the experimental class repeated learning papers for two weeks were used to guide the fixed thinking algorism for each sentence stated math problems. Eight common problems were chosen from a variety of textbooks : number calculation problems, velocity-distance-time problems, the density of a mixture, benefit problems, distribution problems, problems about working, ratio problems, the length of a figure problems. After conducting this research experiment The differences in achievement level between the experimental class and comparative class, were compared and analyzed through achievement tests made from the achievement test papers with seven problems, which were worth seventy points (total score). The conclusions of this thesis are as follows: Firstly, leaning activities through the usage of repeated learning papers for each level class produce an even development of achievement level especially in the case of the upper class learners, they have particular differences (between experimental class and comparative class) compared to the intermediate level and lower classes. Secondly, according to the analysis about achievement development each problems, learners easily accept the strategies of solution through the formula setting up to the problem of velocity -distance-time, and to the density of the mixture they adapted the picture drawing strategies interestingly, However each situation requires a variety of appropriate solution strategies. Teachers will have to employ other interesting solution strategies which relate to real life.

The purpose of this study was to provide high school male shot putters training methods of gliding and delivery motion through comparative analysis of kinematic characteristics. To accomplish this purpose, three dimensional motion analysis was performed for the subjects(PKC, KKH, YDL) who participated in high school male shot putter competition on 92nd (2011), 93rd (2013) National Sports Festival. The subjects were filmed by four Sony HXR-MC2000 video cameras with 60 fields/s. The three-dimensional kinematic data of the glide, conversion and delivery phase were obtained by Kwon3d 3.1 version. The data of the shoulder rotational angles and projection angles were calculated with Matlab R2009a. The following conclusions had been made. With the analysis of the gliding and stance length ratio, the gliding length was shorter at the TG than the SG with short-long technique but the gliding and stance length ratio was 46.8:53.2% respectively. The deviation of the shots trajectory from APSS(Athlete-plus-shot-system) revealed that the PKC showed similar to "n-a-b-c-I" of skilled S-shape type, KKH and YDL showed "n-a-d-f-I'" of unskilled type. Furthermore, they showed smaller radial distance from the central axis of the APSS and the shots were away from the linear trajectory. From this characteristics, The PKC who performed more TG than SG had shorter glide with S-shape of APSS(skilled type) showed the better record than others with technical skill. But KKH and YDL had bigger glide ratio with "n-a-d-f-I'" of unskilled type and improved their records with technical factor. The projection factor had an effect on the record directly. Because PKC maintained more lower glide and transition posture with momentum transfer through COG's rapid horizontal velocity respectively the subject possessed the characteristics of high horizontal and vertical velocity with large turning radius from shot putter to APSS.

The population status of Hydrangea luteovenosa Koidz. in Korea was investigated, with an emphasis on its genetic diversity. From field surveys, we obtained the only locality record for a wild population in Jeju Island, which contained 285 individuals in total. Genotyping was performed using five microsatellite markers for the all extant plants in Korea. Three Japanese populations were also genotyped for the comparative analyses. The genotyping result showed that the Jeju population consisted of only two multilocus genotypes, including identical heterozygous genotypes at two loci; it had been maintained mostly by vegetative reproduction; and although the Jeju population is geographically far from Japanese populations, all alleles observed in the Korean population were shared with Japanese populations, suggesting the possibility that H. luteovenosa in the Jeju Island had been recently migrated or introduced from Japan. Future ecological and genetic studies associated with negative effects of low genetic variation will be essential for determining the conservation direction of the threatened Korean population of this species.
