The following conclusion has been derived from the foregoing results of analysis and observation. First, we found, in this proposed system, reliability, objecivity, and individuality. Second, this type of system must be able to measure numerable testees. Third, testees are regulated that they are brought to the same condition in which their willful adventage are not allowed, Fourth, when considering the foundamental physical strength and skills can be evaluated in general throughout all skills areas of physical education, the following items of skills are recognized to have the advantages and disadvantages which relatively lack or relieve one another. However, under various conditions of the prevailing system of the entrance physical test, the following measurable items of physical skills selected are concluded as having highest validity primarily for the physical entrance examination. 1. Side Step B Style 2. Zigzag Run 3. Wall Pass 4. Standing Long Jump

Body fat generally has been considered to be liable to physical fitness and motor ability. However, very few studies have been done on the relationships between body fat and physical fitness and motor ability. The purpose of this study was to clarify the relationships between percent body fat(%fat) and selected motor ability elements. The subjects were seventy-nine boys and ninety-eight girls aged 10-11 years. Selected motor ability variables were grip strength, back strength, 50-meter dash, running long jump, vertical jump, belly grind, side step, trunk flexion, trunk extension, modified chinning, zigzag dribble, softball throw, and step test. Skinfold thickness was measured at three sites(triceps, subscapular, abdomen)using an Eiken-type caliper. Percent body fat was measured using a tetrapolar bioelectircal impedance plethysmograph(Selco 891). Negatively affected variables by %fat were those which involved muscular power and coordination, while muscular strength was positively related with %fat. Flexibility variables were found not affected by %fat. The subjects were grouped according to %fat in order to further examine the effects of %fat on motor ability. The groups were less than 10%fat(lean), 10∼20%fat(standard)and greater than 20%fat(obese) in boys, and less than 15%fat(lean), 15∼25%fat(standard)and greater than 25%fat(obese) in girls. The results of comparision among groups clearly indicated that the obese groups were poorer in muscular power and coordination but greater in musular strength. The body fat may be one important factor that affects on many motor ability elements. The relationships between motor ability and degree of fatness seem to be rather complicated, and a great deal of data should be accumulated for analysis of influence of body fatness.

Background: Bone marrow transplantation was first introduced to Korean children in 1983. Since then the number of children receiving transplants has increased steadily. Methods: We analyzed two hundred pediatric cases of allogeneic hematopoietic stem cell transplantation between Nov. 1983 and Sep. 2000 in Catholic Hematopoietic Stem Cell Transplantation Center of Korea. Results: HLA-matched sibling transplantations were performed in 146 cases (78 males, 68 females, median age; 10 years) with median follow-up of 47 months. The 3-year estimated event-free survival (EFS) of ALL and AML was 76% and 72% respectively. The 5-year estimated EFS of severe aplastic anemia and CML/MDS was 96% and 73% respectively. The 2-year estimated EFS of nonmalignant rare disease was 86%. Twenty-six children underwent unrelated bone marrow transplantation (UBMT), 15 cord blood stem cell transplanta-tion (CBSCT) and 13 familial haploidentical transplantation (FHT). There were 35 males and 19 females with a median age of 6.5 years and median follow-up of 18.5 months. The estimated 2-year EFS of UBMT, CBSCT and FHT were 56%, 58% and 34% respectively. Conclusion: HLA-matched sibling allogeneic BMT showed better survival in children with hematopoietic stem cell disorder compared to UBMT and CBSCT. Recently, transplants using alternative stem cell source are increasing due to lack of suitable matched sibling donor and continuous efforts for reducing transplant-related complications are warranted for improving survival.

靑少年의 體脂肪率 推定과 肥滿判定 基準作成

金基學 慶北大學校 體育科學硏究所 1992 체육과학연구지 Vol.8 No.-

This study was conducted to estimate the percentage of body fat and to draw up evaluating norms by analizing the tendency of obesity in adolescents. The subjects employed were 2,442 male and female students aged between 12 and 17 years of middle and high schools which are located in medium and small city and big city. Their height, body weight, electrical impedance, and skinfold thickness were measured to calculate body density, and then the percentage of body fat, body fat, lean body mass(LBM), and total body water(TBW) were yield from body density. Validity examination in estimation of % body fat by means of skinfold thickness method was performed through stature indexes such as KI, BMI, RI, and PI which were calculated from height and body weight. The regression equation by independent variables such as body weight, skinfold thickness, height, electrical impedance, and BMI was drawn up to predict body density. Also evaluating norms for obesity by body weight, skinfold thickness, and BMI were drawn up respectively 4 groups;male and female in both middle and high school students. The results obtained are summarized as follows : 1. Percentage of body fat 1) The percentage of body fat by skinfold thickness method was revealed 16.57±3.85% in middle school boys, 20.40±4.97% in middle school girls, 16.41±6.77% in high school boys, and 21.86±4.46% in high school girls. Body density was revealed 1.0610g/㎖, 1.0517g/㎖, 1.0615g/㎖, and 1,0481g/㎖ respectively. In comparision of interregion, percentage of body fat in medium and samll city students was much higher than big city, but showed no difference in middle school and significant difference in high school(p<.001). 2) The percentage of body fat by BI method was 18.58±4.14% in middle school boys, 24.18±5.26% in middle school girls, 16.71±2.97% in high school boys, and 27.41±4.38% in high school girls. And in any case, it revealed higher values than the percentage of body fat obtained by skinfold thickness method. 2. Validity of skinfold thickness method 1) In boys, the correlation between body density and skinfold thickness revealed a significant correlation(p<.001) over all age. In girls, it showed a significant correlation as boys but it was more or less a low value. 2) In correlation among body density by BI method, physique, and stature indices, height and KI index showed no or low correlation, and BMI, RI, and RI index showed high correlation(p<.001) over all age. 3) In correlation between body composition by BI method and that by skinfold thickness method, it revealed high correlation among Db1, %Fat1, Fat1, LBM1, Db2, %Fat2, LBM2, and Fat2 over both male and female in middle and high school students. Therefore, we can interpret that the estimation of %body fat by skinfold caliper method has a sufficient validity. 3. Estimation equation of %body fat Multiple correlation coefficient of estimation equation of %body fat for each subject was about 0.99. The estimation equation was composed by means of skinfold thickness, electrical impedance, and BMI in boy's middle and high school students, and was drawn up from value of electrical impedance and BMI in girl's middle and high school students. Therefore, we can assume a body fat more validly by using above two variables including electrical impedance than by using only skinfold thickness. 4. Evaluation norms for obesity 1) The norms by skinfold thickness method were 33.5㎜ or more in boy's middle school students, 38.0㎜ or more in girl's middle school students, 40.3㎜ or more in boy's high school students, and 40.9㎜ or more in girl's high school students respectively. The ranges of obesity tendency were 26.4-below 33.5㎜, 32.0-below 38.0㎜, 33.7-below 40.3㎜, and 35.0-below 40.9㎜ respectively. 2) The norms by body weight were 68.5㎏ or more in boy's middle school students, 65.4㎏ or more in girl's middle school students, 76.7㎏ or more in boy's high school students, and 67.3㎏ or more in girl's high school students respectively. 3) The norms by BMI were 25.9 or more in boy's middle school students, 26.3 or more in girl's middle school students, 26.1 or more in boy's high school students, and 27.1 or more in girl's high school students respectively. The ranges of obesity tendency were 22.9-below 25.9, 23.3-below 26.3, 23.5-below 26.1, and 24.2-below 27.1 respectively.

男子 大學生의 體力 Test Battery에 關한 硏究

金基學 慶北大學校 1990 論文集 Vol.49 No.-

The purpose of this study was to develope a test battery and evaluation scales for measuring the physical fitness of male college students. 125 male college students, aged 18 to 20, participated as subjects and were administered 20 test items. After the test, estimation equation of factors and evaluation scales for both factor and ability were devised by extraction and interpretation of the factors through factor analysis. The conclusions obtained from this study were as follows: 1. Physical fitness of male college students were composed of 8 factors including explosive strength, speed of changing direction, speed of movement completion, static strength, static balance, static flexibility, muscular endurance, and cardiorespiratory endurance. 2. To measure the interpreted factor, an estimation equation of factors made of standard score was determind, and, by inserting the statistics(mean and standard deviation) of each variable, it was translated into an equation which calculate factor score by using of raw score. 3. A test battery was developed in considering factor loading, reliability, validity, and practicability for each factor. Test items included in the test battery were vertical jump, boomerang run, completion time(back), grip strength, squat thrust, stork stand, trunk extension, and 1500m fast walk. 4. Evaluation scales with 5 grades for both factor and ability were developed to evaluate the test battrry. 5. To develope an estimation scale for ability, mean and standard deviation for each 8 item was divided into 11 grades(from 0 to 10) by C-scale. A perfect score for the test was 80 points. The total score was obtained by applying the raw scores of individuals to this score table. On the basis of the statistics of the obtained total score, the evaluation scale with 5 grades(A,B,C,D, and E) was devised to interpret test scores. ◁표 삽입▷(원문을 참조하세요)

The purpose of this paper is to investigate and analyze the nation's consciousness about the social physical education by regional groups(big cityes, middle cityes, farm village, fishing villge). And the researchers are to find a way to populize this movement. These subjects for this investigation were chosen at random among the citizens in four region. 4,450 sheets of questionnaire were given to the citizen. And 3,587(81%) sheets of them were received from male(2,582) and female(975) citizens. The results of this investigation are as follows: 1. The nation's consciousness has not been still modernized and the nation tend to depend on their doctors rather than on the new active leisure sports, which is a passive and conventional way, to keep their health. 2. Most people have spent their leisures on nonactive hobby such as reading, listening to music, and watching TV rather than sports. 3. Most residents pointed out lack of facilities, and needed professional directors and various programs they could participate. 4. The opening of citizen athletic field and the gymnasiums to citizens was needed to recruit the lack of facility, and the participation to commercial sport ws differed by economical status and leisure time, however, they usually participated such activities as table-tennis, swimning and tennis. 5. To activate social physical education, first of all, an expansion of the facilities such as athletic fields and gymnasium is needed under the active support of government. 6. The facilities for young men and the handicapped is insufficient, and to prevent juvenile delinquency and guide them into the right way, we should lead them out to participate sports activity. And the facility for the handicapped is needed too.
