  • In the previous study (Jee & Park, 2013), family activities, which can be utilized to improve scientific creativity at home have been developed and used. In that study, 12 families fell into two groups, received 6 programs for scientific creativity respectively, and conducted the program for six weeks. As consequences, various positive responses from participants have been received. This survey has been conducted to test whether scientific creativity could be improved quantitatively through family activity at home, and to examine parents' recognition of the feasibility of teaching creativity as well. To answer this, a scientific creativity test consisting of three items in the pre- and post-test respectively have been developed and carried out. The test includes various elements of scientific creativity defined by Park (2011). For obtaining parents' responses, a questionnaire has been developed and applied. The results reveal that parents have changed their thought to 'everyone can conduct scientific creativity activity at home if effective programs are provided and they learn the basic skills to do it.' And, through the scientific creativity test, the experimental group has indicated an improvement in scientific creativity with statistical significance and a large effect size. Therefore, we suggest that family activity for scientific creativity can be applied to family activity in various situations such as camp, leasure or science museum.

  • A new sprout-soybean cultivar, "Hoseo" was developed at the Honam Agricultural Research Institute (HARI) in 2007. Hoseo was selected from a cross between Camp and Nattosan. The preliminary, advanced, and regional yield trials to evaluate the performance of Iksan 57 were carried out from 2003 to 2007. This cultivar has a determinate growth habit with purple flower, grayish brown pubescence, yellow seed coat, grayish brown hilum, rhomboid leaflet shape and small seed size (7.4 g/100 seeds). The maturity date of "Hoseo" is 12 days earlier than the check variety, "Pungsan". It has good seed quality for soybean-sprout and resistance to lodging. This cultivar has resistance to soybean mosaic virus (SMV) and necrotic symptom (SMV-N). The average yield of "Hoseo" was 2.51 ton per hectare in the regional yield trials (RYT) for double cropping carried out for three years from 2005 to 2007.

  • The pts operon, which encodes several factors in the phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS) of Escherichia coli, has multiple promoters which respond to different signals to facilitate quick adaptation to changes in growth conditions. The influence of an 1 kbp DNA region upstream of the pts P0 promoter on pts expression was studied in vitro by employing the DNA templates containing both P0 and P1 promoter with or without the 1 kbp upstream DNA region for in vitro transcription assay. The 1 kbp DNA region upstream of the pts P0 promoter, however, had no effect on pts transcription in vitro. The intracellular concentration of cAMP was measured when cells were grown in the presence of glucose, mannose, or mannitol. The transcription of P0 was increased maximally in the presence of glucose even though the concentration of cAMP in the condition was lowest while the transcription from the P1b was highest when cells were grown in the presence of mannose or mannitol even though the intracellular concentration of cAMP was lower than cells grown in the absence of the sugar. These results suggest the possibility of the existence of a glucose inducible repressor specific for the P0 promoter and a second repressor that is inducible by glucose, mannose and mannitol specific for the P1 promoter.

  • Major statutory nature protection areas include Nature Parks, Nature Reserves. Nature Ecological System Protected Areas. Biosphere Reserves, Nature Protected Forests, Wildlife Sanctuaries, and Protection Forests with total area of 1,124,000 ha. These protected areas cover almost 18% of the forested area. The number of visitors of NPs reached over 33 million per year with sharp increasing rate over the years. To protect the deteriorated hiking trails and camp grounds caused by overuse, two management policies have been implemented : cooking prohibition and natural rest rotation system. While prohibition of cooking is based on the fact that most of the solid wastes in nature parks are leftovers of cooking, natural rest rotation system is mainly for rehabilitation of deteriorated areas by natural processes. The system has closed 47 trails(in 27 mountains) throughout the country since January 1991, which is scheduled to continue 3 years. Due to the lack of accumulated scientific knowledge on how, when and where to close, application of the system leaves much to be desired. This paper discusses the current efforts to protect the natural resources for recreational use and suggests future directions for an effective policy implementation.

  • The aim of this study was to investigate the combined effects of aerobic training and diacylglycerol ingestion on lipid profiles and resting metabolic rate changes in obese men. The subjects were divided into 3 groups: the Diacylglycerol group (D, n=6), aerobic training group (E, n=6), and diacylglycerol ingestion and aerobic training group (DE, n=6). Diacylglycerol was ingested and aerobic exercise training performed for 12 weeks. The information from the research was calculated through a Windows SPSS/PC+ Ver. 12.0K statistics package to standardize the means and deviations for each group. Then, two-way repeated measures ANOVA was used to evaluate the research hypothesis. Percent body fat, blood lipid profiles and resting metabolic rate changes were tested to evaluate the combined effect of aerobic exercise training and diacylglycerol ingestion. The results of this study were as follows; DG ingestion was shown to have a positive effect on body weight and body fat, while having a negative effect on resting metabolic rate changes. However, aerobic training was shown to have a positive effect on all factors including body weight, body fat, and resting metabolic rate. In conclusion, DG ingestion and exercise training were not shown to have synergistic effects on resting metabolic rate changes, percent body fat and lipid profiles, while aerobic exercise training was shown to have a positive effect on resting metabolic rate changes, percent body fat, and lipid profiles. To investigate the therapeutic effect of DG ingestion and aerobic exercise for obese men, analysis of catecholamine, cAMP, HSL, or insulin sensitivity should be considered.

  • To determine ionic species in snowpit samples using ion chromatography system, we described the performance of ion chromatography(IC) system, cleaning method of bottle, and interference by filtering procedure. The limit of detection, reproducibilities, and accuracies determined with BCR$^{(R)}$-408 were 0.01-0.26 ${\mu}g$/L, 0.4-17.4%, 4.5-12.0% for cations and 0.02-0.26 ${\mu}g/L$, 0.1-27.6%, 1.3-5.6% for anions, respectively. Lab blank test for sample bottle indicated that $CH_3CO_2{^-}$, $HCO_2{^-}$, and $NH_4{^+}$ can be easily contaminated in the lab environment. The positive interferences of $NO_3{^-}$ were partly attributed to the cleaning method of bottle. The filtering of melted snow sample should be carefully applied because it can positively affect the concentration levels of some ionic species. Finally, this method was applied to measure ionic species in snowpit samples from the upward area near NEEM camp and the uncertainties of measurement data of $F^-$ were also estimated.
