This study was designed to contribute to the right development of children's physical strength and growth by making a comparative analysis of 6 graders' physical strength with the help of the 6 events of physical strength tests according to sex and trying to work out some relationship between obese children and normal ones. With this in mind, the subjects were 400 elementary students, obese and normal, who reside in Seoul. The results were made by means of the average records and standard deviation test of 6-event physical strength tests per sex and group. The conclusions were as follows; 1. The normal children's average score was better than those of their counterparts, showing a significant difference in the 6-event of physical strength tests. 2. There was a little difference per sex. And there was a significant static interrelations in 4 events except a 100 m race and a standing broad jump when the subjects do well in the two afore-mentioned events. All the other groups minus female normal one show a low interrelations in such events as a 100 m race, a chin-up, and hanging down from the horizontal bar. 3. The obese group was inferior to the normal one regardless of sex. In terms of the physical interrelations, there was no difference among the three groups minus the female normal one.

An antimicrobial compound has been isolated from the leaves of Glochidion superbum. The compound was determined as methyl 3, 4, 5-trihydroxybenzoate (methyl gallate), based on ultraviolet (UV), infrared (IR), nuclear magnetic resonance (NMR) and mass spectroscopy (MS) analysis. The isolated compound exhibited potent antimicrobial activity against three clinical isolates of methicillin resistant Staphylococcus aureus (MRSA) by qualitative agar disc diffusion method and quantitative broth dilution method. Agar disc diffusion was done in a dose-dependent manner for each bacterial isolate at disc potencies of 25, 50, 100, and $150{\mu}g/disc$. The zones of inhibition were on average equal to 12.27, 14.20, 15.43, and 24.17 mm respectively. The inhibition zones were compared with that of vancomycin disc at $30{\mu}g$ as a reference standard. The MIC and MBC values were $50{\mu}g/ml$ and $100{\mu}g/ml$ respectively. The results of anti MRSA activity were analyzed using one-way ANOVA with Turkey's HSD and Duncan test. In conclusion, methyl gallate which was isolated from G. superbum showed the inhibition activity against methicillin resistant S. aureus.

This paper describes the measurement of the underwater noises produced by the engine vibration around the engine room of stern trawler MIS Sae-Ba-Da(2275GT, 3,600 PS) and pole kner M/S Kwan-Ak-San (243 GT, 1000 PS) while the ship is stopping. The underwater noise pressure level was measured with the underwater level meter of which measuring range is 100 to 200 dB(re bLPa). A and B denotes the maximum pressure level measured at right beneath the bottom of the engine room, while the main engine of the Sae-Ba-Da revoluted at 750 and 500 rpm, respectively. C denotes that of the main engine of the Kwan-Ak-San revoluted at 350 rpm, and D that of the generator of the Sae-Ba-Da revoluted at 720 rpm. Thus A, B, C and D were set for the standard sound source for the experiment. The results obtained are as follows: 1. The noise Pressure level at A, B, C and D were 170.5,165,153 and 158dB, respectively. 2. When the check points distanted vertically 1, 10, 20, 30, 40, 50m from the sound source, the underwater noise presure levels were 170.5, 155, 148, 144 and 138 dB and the directional angle was 116\ulcorner in case of A. 3. The sound level attenuated at the rate of 20dB per 10" meters of the horizontal distance from the sound sources. 4. The frequency distribution of the noise was 100Hz to 10KHz and predominant frequency was 700 to 800Hzminant frequency was 700 to 800Hz

Purpose: Scintillation Proximity Assay (SPA) does not require the physical separation of receptor bound form from free form. SPA was applied to the study of interaction of human chorionic gonadotropin (hCG) and $anti-{\alpha}$ hCG in serum. Materials and methods: $Anti-{\alpha}$ hCG was biotinylated for the binding to streptavidin. The assay was based on the simple competitive binding method between $[^{125}I]hCG$ and the hCG in sample serum, with $anti-{\alpha}$ hCG-coated beads. Aliquots of biotinylated $anti-{\alpha}$ hCG were dispensed into scintillation vials containing $100{\mu}{\ell}\;[^125}I]hCG\;and\;200{\mu}{\ell}$ of either a standard concentration of hCG for preparation of standard curve or unknown sample, and incubated for 20 min. at room temperature. Then $20{\mu}{\ell}$ streptavidin-coated beads were added to vials, and finally incubated for 10 min at room temperature. Values for unknown samples were then calculated from the standard curve. Results: Optimal background counts were certificated using varied radioactivity of radionuclides. Appropriate standard curve was obtained from SPA method successively, and the concentration of hCG from unknown serum was determined by standard curve. The result from SPA assay was similar to that of RIA. Conclusion: This observation confirms that SPA method could be useful for clinical diagnosis.

The purpose of this study was to develop men's formal jacket pattern for the Korean males of age 25 to 34 age with an average physique. Through the survey on seven industries of the ready-made men's wear, we investigated size systems and jacket patters presently practiced. From the fitting test of four patterns (three for ready-made jacket patterns, one for educational pattern) the moat favorable and comfortable pattern was selected. New experimented jacket pattern was based on it. The findings were as followed. 1) Survey of the domestic ready-made garment industries showed that each company classified its own manufactured goods according to its own size systems. 2) Anthropometric measurments of forty males for the subjects of lilting test were agreed to the survey of National Anthropometric of Korean(1997). These were also compatible to the standard size (100-88-175) of investigated industries. 3) Experimental jacket pattern was completed through the three times rectification and it gained higher ratings.

During a period from October 1st to November 15th in 1971, We made a survey on hygienic status of kitchen utensils used at 270 college student's home in 9 districts of Seoul city. The results obtained could be summarized as follows. In bacteriological study on the kitchen utensils 20.7% of them revealed contaminations with general bacterial counts of over 100/m1 and 20.0% of them with coliform bacteria. It was probable that degrees of bacterial contamination of the kitchen utensils were chiefly attributable to levels of education of housewives and living standard of individual household. Factors that were presumed to be directly responsible for the contamination were sources and storage of water and methods of washing the utensils. One of the major sources of contamination was derived from the use of a piece of cloth (Hangjoo) to wipe up the utensils after soashing. Hygienic treatment of Hangjoo in urgently needed. Otherwise, it is desirable not to used the Hangjoo and leave the utensils dry after washing them with boiling water.
