Welding structures are designed to endure its expected life. The most important factors are life. Especially on welded structure, fatigue strength is critical. So this study performed a research on Box and T shape weldment specimen to examine the influence of welding type. In this experiment, the results indicate Box shape was available in more than T shape. Fatigue tests were performed to evaluate the fatigue strength of the both as-welded and statically pre-loaded specimens by 3 point bending load. Fatigue life can be improved by using Ultrasonic Impact Treatment(UIT) effect. Ultrasonic Impact Treatment(UIT) is excellent for eliminating the tensile residual stresses and generating compressive residual stresses which elevate fatigue strength of welded structures. Also, this shows that welding part has better fatigue life and welding was performed well. In this study, to evaluate the Ultrasonic Impact Treatment(UIT) effect, for welding structure, the experiment was conducted at various levels of stress range between 100MPa and 500MPa. From the test results, it was indicated that fatigue performance was improving by Ultrasonic Impact Treatment(UIT)

This study was conducted to evaluate the effects of dietary wild-ginseng adventitious root meal on growth performance, blood characteristics and meat quality characteristics in growing-finishing pigs. Ninety six pigs[(Landrace×Yorkshire)×Duroc] with average initial body weight of 68.29±0.31kg were used in 70d growth trial. Dietary treatments included 1) CON(Basal diet), 2) WGR1(Basal diet+0.5% wild- ginseng adventitious root meal), 3) WGR2(Basal diet+1.0% wild-ginseng adventitious root meal) and 4) WGR3(Basal diet+1.5% wild-ginseng adventitious root meal). The pigs were allotted into four dietary treatments with six replicate pens and four pigs per pen in a completely randomized design. For the whole period, final body weight and ADG were increased in CON treatment compared to WGR3 treatment(Linear effect, P=0.005). In blood characteristics, red blood cell(RBC) was significantly increased in CON and WGR2 treatments compared to WGR1 treatment (Quadratic effect, P=0.019). WGR2 treatment resulted in higher white blood cell(WBC) than CON and WGR1 treatments(Linear effect, P=0.041). WBC difference was significantly improved in WGR2 treatment compared to other treatments (Linear effect, P=0.042). Total protein was increased in WGR2 treatment compared to CON treatment (Quadratic effect, P=0.011). In cholesterol concentration of blood, total cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride were not significantly different among treatments. In meet quality, pH in WGR1 treatment was higher than WGR3 treatment(Quadratic effect=0.022). Water holding capacity(WHC) was significantly increased in WGR2 treatment compared to WGR3 treatment(Quadratic effect, P=0.050).

The present study, to evaluate the effect of vitamin E on the oxidative stress in STZ-treated rat and BB rat, was investigated the biochemical enzyme activity in the serum, and malondialdehyde and carbonyl group in the RBC membrane, liver and microsomal fraction after vitamin E and/ or insulin treatment. Results obtained through the experiments were summarized as follows; 1. Effect of vitamin E and/or insulin treatment in STZ-treated rat 1) Lipid peroxidation level in RBC membrane, liver and microsomal fraction was significantly decreased in vi. tamin E and/or insulin treatment group, and especially more significantly decreased in vitamin E with insulin treated group. 2) Protein oxidation level in RBC membrane, liver and microsomal fraction was significantly decreased in vitamin E and/or insulin treatment group. And it was especially more significantly decreased in RBC membrane and liver of vitamin E with insulin treated group. 3) In the enzyme activity in the serum, the activity of AST and ALT was not altered in all experimental group. The increased ALP activity in STZ-treated group was significantly decreased in insulin treated group and vitamin E with insulin treated group. 4) Decreased level of albumin and creatinine after STZ treatment was significantly increased in vitamin E and/or insulin treated group. 5) Level of glucose, cholesterol and triacylglycerol in serum: Glucose level was not significantly different in vitamin E treated group compared to STZ control group. But it was significantly different in the insulin treated group and vitamin E with insulin treated group compared to STZ control group. The cholesterol content in the serum was significantly increased in STZ control group compared to normal control group. And except low dose vitamin E treatment group, it was significantly decreased in vitamin E and/or insulin treated group compared to STZ control group. The triacylglycerol content in the serum was significantly decreased in STZ control group and increased in high dose vitamin E treated group and vitamin E with insulin treated group. But it was not significantly different in low dose vitamin E treated group and insulin treated group compared to STZ control group. 2. Effect of vitamin E and/or insulin treatment in BB rat 1) Lipid peroxidation level in liver was decreased by vitamin E with insulin treatment compared to insulin treatment. But it was not different in microsomal fractions. 2) Protein oxidation level in liver and microsomal fraction was decreased by vitamin E with insulin treatment compared to insulin treatment only in microsomal fractions. These results suggest that the combination treatment of vitamin E and insulin could prevent the oxidative change of lipid and protein of the RBC membrane, liver and microsomal fraction in STZ-treated rats and BB rats.

This study was composed of four treatments [no treatment, phosphate + limestone layer treatment, phosphate + sodium bicarbonate + cement layer treatment, and phosphate + sodium bicarbonate + limestone layer treatment] for figuring out vegetation effects on the acid drainage slope. Treated acid neutralizing techniques were effective for neutralizing acidity and vegetative growth in order of [first: phosphate + sodium bicarbonate + limestone layer treatment, second: phosphate + sodium bicarbonate+cement layer treatment, third: phosphate + limestone layer treatment and fourth: no treatment] on the acid drainage slope. We found out that sodium bicarbonate treatment was additory effect on neutralizing acidity and increasing vegetaive growth besides phosphate and neutralizing layer treatments. In neutralizing layer treatments, Limestone layer was more effective for vegetation and acidity compared to cement layer treatment. Cement layer showed negative initial vegetative growth probably due to high soil hardness and toxicity in spite of acid neutralizing effect. Concerning plants growth characteristics, The surface coverage rates of herbaceous plants, namely as Lotus corniculatus var. japonicus and Coreopsis drummondii L were high in the phosphate + sodium bicarbonate + limestone layer treatment while Festuca arundinacea was high in the phosphate + sodium bicarbonate + cement layer treatment. We also figured out that soil acidity affected more on root than top vegetative growth.

Radiation is one of the major therapy for the removal of cancer cells. The results of the radiation therapy depend on the radio-resistance of cancer cells. For the effective treatment in these radio-resistant cancers, the use of chemicals that act on cancer cells is known to enhance the cytotoxic effects of radiation therapy. In this study, I investigated the effect of potassium cyanate (KCN) on the irradiated-colorectal cancer cell line, HCT 116 cells. KCN induces the carbamylation of proteins and can change the biological activity of various human cells. To understand the effect of KCN on the radiosensitivity of HCT 116 cells, I examined alteration of the cell cycle, generation of reactive oxygen species (ROS), cell viability, apoptosis and intracellular signaling proteins in the irradiated cells with/without KCN treatment. Combination treatment caused significant increase in sub $G_0/G_1$ and ROS generation in HCT 116 cells. KCN inhibited the proliferation and cell viability in irradiated HCT 116 cells. KCN-induced apoptosis of irradiated cells was processed via the activation of caspase 3 and caspase 9. Apoptosis-associated signal proteins, including Bax and Bcl-2 were regulated by irradiation with KCN treatment. Taken together, these results may indicate that KCN enhances the radiosensitivity of radio-resistant cell and then has a synergistic effect on radiation therapy in colorectal cancer.

Seed priming leading to improved emergences, germination speed and uniformity under unfavorable conditions without loss of longevity are the best level of techniques. We studied the possibility to obtain primed seed with reduced mean germination time (MGT) and uniformity but with simple, fast and effective methods. The experiments were carried out at $15^{\circ}C$ for 16 hours with priming treatment. To compare the effects of each treatment, we used 200mM $CaCl_2$ priming or hydro priming or no imbibition after ultrasonication or red light treatment. The light treatment was performed by irradiating 2000 lux of red light for 15, 30, 60, and 120 minutes. Addition, in order to investigate the effect of the priming solution, treated at 200mM $CaCl_2$ for 8 hours. Ultrasonication treatment was performed for 5, 10, and 20 minutes at exposures of 13.0, 17.3, and 21.6 kHz during priming. For liquid smoke (LS) treatment, seed soaked in 0%, 0.5%, 1.0%, 5.0% and 10.0% of diluted water and 200mM $CaCl_2$ solution. After each treatment, the seeds were dried to moisture content ranged 5-8% at $25^{\circ}C$ for 24 hours. The effect of seed treatment was evaluated with germination percentage (GP), MGT, germination index(GI), germination rate(GR), Germination Uniformity(GU) and heath seed percentage(HS). For several factors tested, we found that the desired germination improvement could be obtained by treating the seed with ultrasonication at 17.3 kHz for 5 minutes in water or red light exposure at 2000 lux for 120 min in water that resulted very similar to those used to 200mM $CaCl_2$ priming for 16 hrs. However, LS treatment showed no improvement in all diluted solution. Therefore, the methods applied ultrasonication and red light treatment showed high potential for fast and easy treatment avoiding pollution of salt solution waste.
