Maximal oxygen consumption measurements were performed on 15 middle school boys (age: mean 14.0, range: $13{\sim}16$ years) and 14 high school boys (age: mean 17.4, range: $16{\sim}19$ years). General body build was greater in the high school boys and absolute values of body height, body weight, skinfold thicknesses, maximal oxygen uptake, and maximal pulmonary ventilation followed the same trend. Considered on the basis of body build, however, the values of high school boys were not always greater than those of middle school boys. The following results were obtained. 1. Maximal oxygen consumption in middle school boys was 2.11 l/min., 53.7ml/kg b. weight, 13.9 ml/cm body height, and 63.7 ml/kg LBM. In high school boys the values were: 2.86 l/min., 52.7 ml/kg b.wt., 17.5 ml/cm b. height, and 57.9 ml/kg LBM. Thus, middle school boys were superior to high school boys on body weight and lean body mass basis. They were also superior to the European boys of the same age. 2. The ratio of maximal oxygen uptake to resting value was 9.7 in middle school boys, and 10.8 in high school boys. 3. Maximal pulmonary ventilation in middle school boys was 58.0 l/min., and 84.0 l/min. in high school boys. The ratio of maximal ventilation to resting value was the same as oxygen uptake, namely, 9.7 in middle school boys and 10.7 in high school boys. 4. Ventilation equivalent in middle school boys was 27.5 and 29.3 in high school boys. These values represent values of untrained male subjects. 5. Maximal heart rate in high school boys reached to 193 beat/min. and is 2.9 times that of resting heart rate. 6. Maximal oxygen pulse in high school boys was 16.6 ml/beat and was same as that of untrained subject. 7. Correlation between body weight and maximal oxygen consumption in middle school boys was r=0.570, and r=0.162 in high school boys. Correlation between lean body mass in middle school boys was r=0.499, and r=0.158 in high school boys. Interrelation between body weight and maximal pulmonary ventilation was poor. 8. The differences between trained and untrained subjects were discussed.

We must encourage the use of the spirometer as part of routine examination of nearly all adult patients. Despite the theoretical problems of the water spirometer and its Poor frequency response, the water spirometer is adequate for the physiological function tests even in healthy people. The aim of this study was to report the pulmonary function studies of athletic swimmers. Subjects were 85 athletic swimmers from 9 to 25 years of age. They were elementary school boys and girls, middle school boys and girls, high school boys and girls, and college students. The results are as follows: 1) Frequency of breath: (cycle/min, $M{\pm}SD$) Elementary school boys show $19{\pm}4.7$, elementary school girls $22{\pm}7.9$, middle school boys $17{\pm}2.4$, middle school girls $18{\pm}8.2$, high school boys $15{\pm}3.4$, high school girls $15{\pm}9.7$, and college male students $12{\pm}3.2$. 2) Vital capacity: (1, $M{\pm}SD$) Elementary school boys show $2.60{\pm}0.480$, elementary school girls $2.22{\pm}0.412$, middle school boys $3.63{\pm}0.598$, middle school girls $2.80{\pm}0.303$, high school boys $4.70{\pm}0.487$, high school girls $3.23{\pm}0.509$, and college male students $4.30{\pm}0.608$. 3) Tidal volume: (ml, $M{\pm}SD$) Elementary school boys show $462{\pm}59$, elementary school girls $395{\pm}110$, middle school boys $524{\pm}78$, middle school girls $421{\pm}59$, high school boys $612{\pm}101$, high school girls $494{\pm}123$, and college male students $603{\pm}121$. 4) Breath holding time: (sec, $M{\pm}SD$) Elementary school boys show $58{\pm}21.2$, elementary school girls $36{\pm}11.1$, middle school boys $61{\pm}16.7$. middle school girls $53{\pm}21.0$, high school boys $64{\pm}9.1$, high school girls $49{\pm}15.3$, and college male students $81{\pm}23.0$.

The objective of this study is to compare and analyze middle and high school boys' and girls' uniform wearing conditions. The survey was conducted online and data were obtained from 907 middle and high school boys and girls. The results of this study are as follows. First, most boys and girls did not know their body sizes other than their height and weight. Second, when purchasing the school uniforms, over 70% of the boys and girls chose to try on the uniforms before their purchase and over 60% of the boys and girls had trouble selecting their sizes just by reading the labels. Third, both boys and girls considered the fit as the most important factor. When purchasing jackets, both middle and high school boys considered the shoulder width as most important. Middle school girls considered the jacket and sleeve length as most important, whereas high school girls considered the shoulder width, waist, and bust as most important. When purchasing skirts or slacks, waist girth was considered as most important. Fourth, boys repurchased more school uniforms than girls. Boys have outgrown their uniforms usually in the length categories, whereas girls have outgrown in the girth categories. Fifth, more girls(72.7%) modified their uniforms than the boys(56.8%). Boys usually bought bigger uniforms, modified them to fit and when they grow out of their uniforms they planned to modify their uniforms again whereas girls modified their uniforms to follow the trend. Sixth, the online shopping mall survey has revealed that both boys and girls liked the idea of 3D model that reflect their own body shapes, but they had low preference to purchase school uniforms online. Online purchase has been more attractive to the boys than to the girls, while the way of fashioning uniforms has been more attractive to the girls than to the boys.

The purpose of this study was to investigate the relationships among snacking behaviors and depression in middle school students. A survey was conducted on 777 middle school students (491 boys and 286 girls). Using a self-reporting method, the participants took 20 minutes to complete the questionnaires. Our data revealed that the height and weight of boys were 172.66 cm and 63.48 kg, respectively, whereas those of girls were 159.86 cm and 51.62 kg, respectively. Sleep durations of boys and girls were 6.44 and 6.41 hours, respectively. Boys ate more rice cake than girls, whereas girls ate more biscuits than boys. The average B.D.I (Beck Depression inventory) scores for boys and girls were 9.73 and 11.49, respectively. Degree of depression was significantly higher in girls compared to boys. We also observed significant correlations between depression and snacking (rice cake, biscuits, chocolate, and fried potato). This study may provide basic information on snacking behaviors and depression in middle school students, and the findings suggest that proper control of emotions is required to maintain desirable eating behaviors in middle school students.

Objectives: The aim of this study was to compare the knowledge and attitudes about AIDS between an activity-oriented and a lecture-oriented AIDS prevention education in middle school boys. Methods: Each of 60 middle school boys in M city, Gyeongsangnam-do, was assigned to the experimental or control group. The activity-oriented AIDS prevention education in experimental group and the lecture-oriented education in control group were provided for a 45 minutes class per week for 4 weeks, respectively. Date were collected with questionnaires and analyzed through $x^2$-test, t-test, and repeated measures ANOVA. Results: The experimental group and control group were homogeneous in knowledge and attitudes about AIDS prevention before the study. In AIDS prevention knowledge, there was no significant interaction of times by groups (F=0.033, p=.930); but the main effect of times was significant (F=63.950, p<.001). In attitudes toward AIDS, there was a significant interaction of times by groups (F=8.892, p<.001). Conclusion: The activity-oriented AIDS prevention education was an effective teaching strategy to foster positive attitudes toward AIDS prevention in middle school boys. Therefore, systematic and sustained development of AIDS prevention education reflecting learners' characteristics is required.

본 연구에서는 남, 여 중학생의 체형인식에 딱른 외모관리 행동의 실태를 파악하고 비교 분석하여 청소년의 긍정적인 신체이미지 형성의 바람직한 방향을 제시하고자 하였다 조사 대상자는 광주소재 남 여 공학 중학교 7곳의 2. 3학년에 재학중인 435명의 남, 여중학생이었다. 결과분석은 SPSS Package 12.0(Kr)을 활용하였다. 그 결과를 요약하면 다음과 같았다. 먼저, 남, 여중학생들은 실제체형보다 비만하게 인식하는 것뿐만 아니라 실제체형보다 수척하게 인식하는 경향도 컸다. 자신의 체형을 제대로 인식할 수 있는 교육이 필요하다고 본다. 둘째, 신체인식 요인과 외모관리행동의 상관관계를 살펴보면 남, 여 중학생 모두 비만인식에 대해 운동보다는 다이어트로 외모관리를 하는 경향을 보이는데 이것에 대한 적절한 지도가 필요하다고 생각된다. 셋째, 자신의 실제체형보다 수척하게 인식하는 수척왜곡 인식집단과 정상집단의 외모관리행동을 살펴보면 남중학생은 운동관리만 하고 여중학생은 운동관리만 하지 알았다. 서로 차별화된 교육이 필요하다고 생각된다. 넷째 비만왜곡인식집단은 남 여중학생 모두 다이어트관리를 하는 반면 신체보정관리나 운동관리를 하지 않는 경향을 보였다. 실제적으로 운동관리가 가장 필요하다고 인식해야할 집단이 다이어트에만 의존하는 경향은 시정이 꼭 필요하다고 생각된다. 이상과 같이 우리나라 남 여 중학생의 왜곡된 신체인식과 외모관리행동을 바로 잡기 위해서 정규 교과목인 가정과목을 통해 표준체형에 대한 교육이 이루어져야 할 것이며 자신의 실제체형을 올바르게 인식할 수 있도록 하는 지도가 병행되어야 할 것으로 생각된다.
