Purpose: This study was designed to examine increase in hamstring muscle extensibility with ballistic stretching, static stretching, hold- relax, and hold-relax-agonist techniques. Materials and methods: Subjects were designed randomly to passive stretching, static stretching, hold- relax, and hold-relax-agonist techniques. A total of 40 subjects, with limited hamstring flexibility (defined as 30° loss of knee extension measured with the tight held at 90° of hip flexion) were recruited for this study. Hamstring muscle extensibility was measured using the passive 90/90 test before and after the 3-weeks program. the range of knee extension was measured by Goniometer(made in USA). Data analysis were compared the flexibility within treatment period on each group after program by repeated measure 2- way ANOVA using SPSS for window Results: Difference were signification for test and for the test by-group interaction. 1. All stretch technique programs produced a greater decrease in knee extension range within treatment period on each group (p<0.05). 2. The hold-relax-agonist technique produced a greater decrease in knee extension range than did passive stretch, static stretch, and hald-relax (p<0.05). 3. passive stretching technique produced a lesser decrease in knee extension range than did other stretch technique programs (p<0.05)

Objective: The purpose of study was to verify the most effective abdominal muscles exercise by comparing the activity of upper and lower rectus abdominus according to four types of exercise (dynamic and static double leg raise, dynamic and static curl-ups exercise). Design and Setting: A one-way analysis of variance (ANOVA) was performed to determine significant differences of activity between each muscles during each of the four different exercises Tukey HSD was then applied (p<.05). All testing was performed in a college laboratory Subjects: Ten healthy students were recruited and each subjects performed four types of exercises. Measurements: Surface EMG activity was recorded from the both upper and lower rectus abdominus while the 4 exercisesdynamic and static double leg raise, dynamic and static curl-ups exercises were performed in different positions (dynamic and static supports). The static position was supine in the crook-lying position, the dynamic position was supine in the crook-lying position, and pelvic supported on a balance pad. peak activity was normalized to a maximum voluntary isometric contraction for upper and lower rectus abdominus. Results: For the rectus abdominus, there was an interaction between position and activity. The EMG amplitude of upper rectus abdominus was high in static curl-ups exercise. EMG amplitude of lower rectus abdominus was high in static curl-ups exercise. The type of dynamic double leg raise did affect the activity of lower rectus abdominus. Conclusion: The type of static curl-ups was more effective than dynamic curl-ups exercise. The type of double leg raise usually was thought to strengthen of lower abdominus.

We investigated seasonally the distribution of phytoplankton and physico-chemical factors at four stations of downstream water in Han-river from April to October 2004. The phytoplankton collected in this study was totally 135 taxa that belongs to 4 phylums 4 classes 13 orders 5 suborders 19 families 2 subfamilies 52 genera 120 species 1 subspecies 14 varieties. Chrysophytes revealed to the dominant division that they occupied 72 taxa as 53.3% among totally occurring taxa. The indicator of clean water was Surirella splendida, and the indicator of pollition water was 20 taxa including Oscillatoria formosa in this study. In the seasonal analysis of water quality and phytoplanktons, it was appeared that the downstream waters of Han-river was polluted deeply at summer and autumn.

For upward cocurrent gas-liquid flow in a fixed bed reactor, the flow and axial dispersion of liquid were investigated in an air-water-Zeolite particle system. Based on experimental residence time distributions, parameters of mixing models were evaluated with two proposed liquid mixing models: axial dispersion model with stagnant zone(DSM) and plug flow model with stagnant zone(PFM). Accordingly, the applicability and parameters of each mixing model were analyzed for various operating conditions. We found that the flow and axial mixing characteristics of liquid could be analyzed well by DSM and parameters were well estimated by curve fitting using trial and error method. Also, the fraction of stagnant zone was decreased with increasing liquid velocity, while the dimensionless mass transfer coefficient between dynamic and stagnant zones was increased, and these parameters estimated by DSM were lower than those by PFM. In dynamic zone, calculated Peclet number were increased with increasing liquid velocity and axial mixing characteristics of liquid tended to access to plug flow for the high liquid Reynolds number(about Re1>50). For the porous catalyst particle system the flow and axial mixing characteristics of liquid had nearly same tendency that for the nonporous particle(glass bead) system, while dimensionless mass transfer coefficient was lower value than that for it. In these conditions, correlations of these parameters were obtained for various operating conditions.

The purpose of the study is to show the direction toward consumer education in the home, schools and throughout society. This study also makes reference to internal and external literary sources and is supported by the result of a survey of more than 350 housewives in Seoul. The focuses of the study are on the following aspects; (1) to identify the content of consumer education, the attendment of consumer education, consumer behavior, consumer consciousness, purchase behavior which can be applied to the housewives in home. (2) to analyze the correlation coefficient between the content of consumer education, the attendment of consumer education, consumer behavior, consumer consciousness, purchase behavior of the survey. (3) To find out which factors of independent variables (i. e., housewives edcationa level, residential area, income of a month, number of children, length of marriage) have significant effect on housewives' consumer education practice. PROCEDURE Research was conducted from Sep. 20th to Sep. 29th, 1982 on 350 housewives. The sample were selected randomly from 7 middle schools in Seoul. The questionnaire especially developed by the researcher is consisted of 45 questions (9 questions for background information, 36 Likert-type questions for housewives' consumer education practice). The questions were used after such tests like face-validity test by professors in consumer education, pre-test on the sample of 10. The statistical method used are Percentile, Analysis of Variance. (X￣ and F values), and Pearson product moment correlation coefficient. FINDING & CONCLUSIONS As a result of the survey, it has been determined that all of the factors(housewives' educational level, residential area, income of a month, number of children, length of marriage) influence on consumer education practice. Concerning residential areas, apartment living seems to have a greater influence in increasing higher consumption in contrast to living in private houses. Most consumers have a positive attitude toward consumer education but tend not to take any action to develop such courses. The effect of consumer education was greater in the part that well-educated on housewives. Consequently, consumer education should be conducted with consideration of the following points: (1) Consumer education must be conducted with the stage of development of children to have the right consumer consciousness and must be made curriculum toward social change. (2) Consumer education must be related with science to practical exercises. (3) Consumer education on housewives should be reinforced to educate children in homes. (4) Government of an educational department for consumers should help to practice the consumer education methods and professions.
