This study is to investigate the effect of the pet insect therapy. The pet insect program was provided with 7session from May 2014 to July 2014. The measures used in this study includes self-esteem scale, social competence scale and stress scale. For analyses, t-tests with pre-test and post-test scores of experimental group and control group by SPSS 18.0. Regarding the results insect group who participated in the pet insect program showed higher mean scores in Self-Esteem scale, Social Competence Scale and stress Scale than those of control group. Mean score differences were statistically significant in at least p<0.01 level. The study results means that the pet insect program had effects on the improvement of Self-Esteem, Social Competence and reduce stress for elementary school children.
To examine the expression profile of oxidative stress responsive genes in Spodoptera litura, we constructed a cDNA library from S. litura injected with hydrogen peroxide (H2O2). Using a microarray chip composed of 2,964 cDNAs, we screened gene expression at 1, 3, 5, 7, and 9 h post H2O2 injection. Data were clustered into 15 groups of genes that behave similarly across each time course. Seventy-three genes were identified as being at least 2-fold up- or downregulated after treatment with H2O2 in S. litura. We constructed expressed sequence tags (ESTs) for genes that changed at least 2-fold after treatment with H2O2. The functional classification of these ESTs based on Gene Ontology showed that the ESTs are rich in genes involved in oxidoreductase activity (5.7%), defense (14.3%), cellular process (22.9%), and development (17.1%).
For studying of coagulation and sedimentation in estuarine clay, we obtained several flow curves with various concentrations of sea water by using Coutte type rotational rheometer. The initial shear stress on high concentration of sea water was observed big, but after this, its value is decreasing with increasing shear rate. The maximum pick of shear stress is decreasing with the decreasing of concentration of sea water. The trend is same totally above for viscosity. The sedimentation times with the concentration of sea water vary in ∞ ∼ 5 minutes.
The zeta potential is changed dramatically between 1/4 and 1/8 concentration of sea water. That is consistent with the sedimentation graph. From these results, the phenomena of coagulation and sedimentation can be explained with viscoelastic terms on structual formation among particles by the changes of surface potential affected from contacting sea water to dispersed particles.
