This study analyzed the influence of Qigong exercise intervention upon a change in glucose, blood lipid, and SFT(senior fitness test) of elderly women and to closely examine the efficacy of a Qigong exercise intervention to promote the health of older women. As research subjects, 24 elderly women aged over 80 were divided into Qigong group(n=12) and control group(n=12), respectively, and the program was carried out for 60 minutes per a day, five times per week for 24 weeks. Data were analyzed using SPSS WIN 20.0, repeated measures ANOVA. The Qigong group had a significantly lower glucose level than the control group. Second, the blood lipid and neutral fat(TG) was reduced significantly in the Qigong group than the control group. The total cholesterol(TC), high-density lipoprotein(HDL-C), and low-density lipoprotein(LDL-C) did not show a significant difference. Third, as for SFT, the leg strength, leg flexibility, and total body endurance were significantly higher in the Qigong group than in the control group. Therefore, Qigong has an influence on the reduction in glucose and neutral fat(TG) and upon the improvement in SFT(leg strength, leg flexibility, and total body endurance) of elderly women, and may show effectiveness as an exercise prescription program for older women.

The purposes of this study were to observe the effects of the exercise programs which have different order of walking and resistance exercises on the composition of the abdominal fat and the blood lipid profiles of the obese college women and to provide basic materials for the development of more effective and more efficient exercise program in order to reduce and prevent obesity. Classification of group, "A" group(resistance exercise after aerobic exercise) is a group of 12 people, "B" group(resistance exercise after aerobic exercise) is a group of 12 people. To determine the abdominal fat, intestine fat area, subcutaneous fat area, ratio of intestine fat area/subcutaneous fat area were analyzed, while for the blood lipid profiles, total cholesterol, triglyceride, high density lipid protein, and low density lipid protein were analyzed. First, there was statistically significant difference in the interaction in the abdomen subcutaneous fat. In the post analysis, the Resistance first group showed significantly more reduction to confirm that there was difference according to the order of the exercises. Second, there was statistically significant difference in the interaction effects in the factor of triglyceride. In the post analysis, the Resistance first group only showed significant reduction in the triglyceride to confirm that resistance exercise followed by aerobics would be better for the reduction of the triglyceride.

This study aims to develop a modeling-based learning program about geologic structures and to reveal the relationship between the argumentation patterns and levels of students' mental models. Participants included 126 second grade high school students in four sessions of modeling-based learning regarding continental drift, oceanic ridges, transform faults, and characteristics of faults. A modeling-based learning program was implemented in two classes of the experimental group, and teacher-centered traditional classes were carried out for the other students in the comparison group. Science achievement scores and the distribution of students' mental models in experimental and comparison groups were quantitatively compared. The video-taped transcripts of five teams' argumentation were qualitatively analyzed based on the analytic framework developed in the study. The analytic framework for coding students' argumentation in the modeling-based learning was composed of five components of TAP and the corresponding components containing alternative concepts. The results suggest that the frequencies of causal two-dimensional model and cubic model were high in the experimental group, while the frequencies of simple two-dimensional model and simple cross sectional model were high in the comparison group. The higher the frequency of claims, an argumentation pattern was proven successful, and the level of mental model was higher. After the rebuttal was suggested, students observed the model again and claimed again according to new data. Therefore, the model could be confirmed as having a positive impact on students' argumentation process.

The purpose of this study was to analyze the effect of a 12 week aerobic resistance training circuit program on the health-related fitness, blood lipids, and cortisol in obese postmenopausal women. The subjects for the study were twenty obese postmenopausal women composed of the exercise group (n=10) and "no exercise" control group (n=10). The aerobic resistance training circuit program was conducted for 70 minutes 3 times a week for 12 weeks, in which the aerobic exercise consisted of 5 items each composed of 5 sets of aerobic exercise at 50-70% HRmax intensity for 1 minute for a total of 25 minutes and the resistance exercise consisted of 8 items conducted for a total of 25 minutes at 40-60% intensity of 1RM). In the exercise group, the body weight and BMI significantly decreased and the 20m shuttle run, sit-ups and sitting trunk flexion significantly increased. In the exercise group, the TC, LDL-C, and TG significantly decreased. Also, it was noted that the HDL-C was slightly higher in the exercise group than in the control group, but the difference was not statistically significant. The cortisol levels of the exercise group and control group at baseline were similar. However, after the aerobic resistance training circuit program, the exercise group had a significantly higher cortisol level than the control group. Therefore, regular and continuous aerobic resistance training was effective in improving the body composition, blood lipids and health-related fitness.

This study aimed to identify differences in soil properties and geological characteristics between slow-moving landslide prone areas and areas without landslide (control areas) in the Republic of Korea. During this 3-year field surveys (2019-2021), 11 soil and geological parameters were measured at 300 sites, i.e., 107 slow-moving landslide prone areas and 193 control areas. T-tests were conducted to identify differences in field-observed parameters between the two areas, followed by χ²-tests and density plots considering distribution patterns of the sample groups. We identified statistically significant differences between the areas in terms of soil internal friction angle, weathered rock thickness, bedrock thickness, and number of major geological anomaly zones. In conclusion, slow-moving landslide prone areas exhibited significant differences in geological characteristics, such as stratum thickness and presence of anomaly zones, compared with the control areas. To better understand the relationship between the geological characteristics identified in this study and the occurrence of slow-moving landslides, further field data collection and systematic analyses are warranted.

The purpose of this study is to determine geochemical characteristics for stream sediments in the Gwangju area. We collect the stream sediments samples by wet sieving along the primary channels and dry these samples slowly in the laboratory and grind to under 200mesh using an alumina mortar fur chemical analysis. Major elements, trace and rare earth elements are determined by XRF, ICP-AES and NAA analysis methods. For geochemical characteristics on geological groups of stream sediments, we separate geologic groups which are derived from Precambrian granite gneiss area, Jurassic granite area and Cretaceous Hwasun andesite area. Contents range of major elements for stream sediments in the Gwangju area are $SiO_2\;51.89\~70.63\;wt.\%,\;Al_2O-3\;12.91\~21.95\;wt.\%,\;Fe_2O_3\;3.22\~9.89\;wt.\%,\;K_2O\;1.85\~4.49\;wt.\%,\;MgO\;0.68\~2.90\;wt.\%,\;Na_2O\;0.48\~2.34\;wt.\%,\;CaO\;0.42\~6.72\;wt.\%,\;TiO_2\;0.53\~l.32\;wt.\%,\;P_2O_5\;0.06\~0.51\;wt.\%\;and\;MnO\;0.05\~0.69\;wt.\%.$ According to the AMF diagram for stream sediments and rocks, the stream sediments are plotted on boundary of tholeiitic series and calk alkaline series, which shows that contents of $Fe_2O_3$ are higher in stream sediments than rocks. According to variation diagram of $SiO_2$ versus $(K_2O+Na_2O),$ stream sediments are plotted on subalkaline series. Contents range of trace and rare earth elements for stream sediments in the Gwangiu area are Ba$590\~2170$ppm, Be1\~2.4$ppm, Cu$13\~79$ppm, Nb$20\~34$ppm, Ni$10\~50$ppm, Pb$17\~30$ppm, Sr$70\~1025$ ppm, V$42\~135$ppm, Zr$45\~171$ppm, Li$19\~77$ppm, Co$4.3\~19.3$ppm, Cr$28\~131$ppm, Cs$3.1\~17.6$ppm, Hf$5\~27.6$ppm, Rb$388\~202$ppm, Sb$0.2\~l.2$ ppm, Sc$6.4\~17$ppm, Zn$47\~389$ppm, Pa$8.8\~68.8$ppm, Ce$62\~272$ppm, Eu$1\~2.7$ppm and Yb$0.9\~6$ppm.

The aim of this study was to analyze the effects of aerobic exercise on the blood lipids, leptin, ghrelin, and HOMA-IR factors in obese postmenopausal Korean women. Thirty-six healthy postmenopausal women (mean age, $54.47{\pm}2.50$ years) with >32 % body fat were assigned randomly to an aerobic exercise group (n = 18) or to a "no exercise" control group (n = 18). The subjects' body composition, blood lipid, leptin, ghrelin levels, and HOMA-IR were measured before and after a 16-week line-dancing program. The exercise group showed a significant decrease in body weight, percent body fat, body mass index, visceral fat area, leptin, insulin, glucose, HOMA-IR, total cholesterol, triglycerides, apolipoprotein B, low-density lipoprotein cholesterol, and systolic and diastolic blood pressure. In addition, this group exhibited a significant increase in the apolipoprotein A-I, ghrelin, and high-density lipoprotein cholesterol levels. The energy metabolic factors that influenced the visceral fat included ghrelin, leptin, insulin, glucose, and HOMA-IR. The t-value, which determined the statistical significance of the independent variables, was significant for ghrelin, glucose, insulin, and HOMA-IR (p < 0.05). Regular and continuous aerobic exercise (e.g., line dancing) effectively improved the body composition, visceral fat, serum blood lipids, leptin, ghrelin, and HOMA-IR factors in obese postmenopausal Korean women.
