  • The purpose of this study was to explore the effects of adolescent consumers' attitudes toward money and conspicuous consumption on unethical consumption behavior in commercial transactions. The main survey was conducted targeting 290 middle and high school students. As a result of this research, first in the case of adolescent's attitudes toward money, the symbol for happiness and success was 3.11 and the means of control was 1.77 respectively. The level of conspicuous consumption behavior was 2.75 and the level of unethical consumption behavior scored as passive unethical consumption behavior was 1.38 while the active unethical consumption behavior was 2.10. Second, in the case of the attitude toward money as a means of control, it differentiated according to the level of living and the amount of allowance. Conspicuous consumption behavior differentiated according to the amount of allowance and the father's education. Active unethical consumption behavior showed a difference according to the amount of allowance and the father's education. Multiple linear regression analysis conducted to identify relative effects of the variables that affect unethical consumption behavior, in case of passive unethical consumption behavior, showed that conspicuous consumption(${\beta}$=.23, p<.01) and attitudes toward money as a means of control(${\beta}$=.29, p<.001) with an explanatory power of 18%. In the case of active unethical consumption behavior, showed that sex(${\beta}$=.16, p<.05), father's education(${\beta}$=-.15, p<.05), attitudes toward money as means of control(${\beta}$=.18, p<.5) and conspicuous consumption(${\beta}$=.36, p<.001) with an explanatory power of 26%.

  • In this paper, an experimental study was conducted to investigate the performance of the spherical ice particle production system which uses the technology of water spray in a vacuum chamber for increasing the heat transfer area. As a result, following conclusions were obtained. The diffusion-controlled evaporation model agreed relatively well with experiments. The spray flow rate influences the performance of the system rather than any other factors, for example, the spray nozzle position, the nozzle number. As the spray rate increases, the system efficiency increases. It is due to the entrainment of small droplets among the spray with the exhausted vapor. Thus the system should be designed and operated to prevent the entrainment. Assuming the compressor efficiency to be 70%, the COP of the system reaches highly up to 6 at a maximum spray rate. Under the conditions, however, the rigid ice layer is obtained because ice particles bond together with increase of the spray rate. Therefore, the spray rate should be controlled properly to make the spherical ice particles.

  • An experiment was conducted to determine the effect of supplementation of chlortetracycline (CTC,110ppm), copper sulfate(Cu, 125ppm) and two levels of probiotics(Prob I, 0.04%, Prob II, 0.1%), Bacillus licheniformis and Bacillus subtilis) on growth performance, nutrient digestibility and manure characteristics in growing pigs. A total of 50 pigs that averaged 20.78$\pm$0.35kg BW and 50$\pm$2.3d age were allocated in a randomized block design with two pigs per pen and 5 pens per treatment. Pigs and feeders were weighed 10-days interval for the 40-d trials to determine ADG, ADFI and feed:gain ratio(F:G). Average daily gain, feed intake, feed/gain and nutrient digestibility were not improved(P>0.10) by the supplementation of CTC, Cu and two levels of probiotics. There were significant(P<0.05) Cu effects on digestibility of crude protein, and probiotics effects on digestibilities on organic matter, crude protein and energy between first 20 days and subsequent 20 days. Fecal concentrations of copper were highly increased(P<0.001) by the copper supplementation. Total bacteria and coliform counts were not altered by the supplementation of CTC, Cu and two levels of probiotics. Ammonia emission from slurry, measured during first 3 weeks, was reduced (P<0.001) in pigs fed diet with 125 ppm copper from copper sulfate. Results indicate that CTC, Cu and Probiotics supplementation had a little or not positive effect on grower pig performance under sound environmental conditions. Further studies may be warranted to investigate the effects of dietary copper-either reduced or in combination with dietary ammonia control agents-on the ammonia emission characteristics of swine manure.

  • The purpose of this study was to investigate the causal relationship among perceived value, satisfaction and revisit intention for visitors of the Korea National Arboretum. Three hundred respondents were selected by quota sampling, and well-known measurement scales utilized in marketing field were adopted in order to measure three variables with some modification to apply for arboretum visitors. Results of structural equation model showed that perceived value affected visitors' satisfaction, which in turn influenced revisit intention. Specifically, "emotional value" had the most significant influence on satisfaction, followed by "value for money" and "novelty value"; however, "social value" was not an influential construct. Based on calibration results, several strategies were suggested for the effective management. Authors advised that (a)improvement of measurement scale of value, (b)inclusion of self-congruity as antecedent variable to satisfaction, (c)changing revisit intention to word-of-mouth communication as a post-purchase behavioral intention, and (d)implementation of market segmentation should be considered for future research.

  • Using the materials collected from nine farms in a three-way cross system to produce commercial pigs produced from F1 sows (Landrace $\times$ Large White) $\times$ Duroc, the power of individual discrimination and parentage of the 13 microsatellite (MS) marker set that has been suggested for individual/brand identification (traceability) was empirically tested. Initially, genotypes of the parental population ($F_1$ sows and Duroc), and commercial pigs were determined and the genotype frequency and polymorphic index were estimated using the Cervus 2.0 program. The probability of identity among genotypes of random individuals, that random half sibs and that of full sib individuals, based on the genotypes from 91 $F_1$ sows and Duroc were expected to be $4.94{\times}10^{-34}$, $8.16{\times}10^{-23}$ and $2.01{\times}10^{-08}$, respectively, using the API-CALC version 1.0 program. When commercial pigs were included, the estimates increased to $3.74{\times}10^{-35}$, $5.48{\times}10^{-25}$ and $2.96{\times}10^{-11}$, respectively. For the empirical verification of the estimated powers of individual discrimination and parentage, the parentage test was performed for 452 commercial pigs using PAPA version 2.0, and individuals with the same genotype were investigated using the Cervus version 2.0 program. Parents for all commercial pigs were successfully estimated and no identical individual was identified in the pedigree. Although the individual discriminating power was not fully verified because of the lack of individuals corresponding with the theoretical power, the 100% efficiency of parentage test was clearly confirmed. Therefore, we believe that the 13 MS marker set in conjunction with management record/information for the pig production kept in a farm/brand should be useful in the pork traceability in a brand unit.

  • The effects of microbial phutase on laying performance and phosphorus utilization were examined at different levels of dietary nonphosphorus(NPP) in 320 23-week-old Hy-line brown hens for 12weeks. Diets were formulated 0.275%(T1), 0.220%(T2), 0.165%(T3) of NPP levels, and supplemental microbial phytase was 300DPU/kg diet constantly. Conventional diet(C) was formulated 0.275% NPP level without microbial phytase. Egg production and egg mass were higher in T2 than the others (p<0.05), and average egg weight was higher in T1 than the other (p<0.05). Egg productivity was tended to increase with supplemental phytase compared to conventional diet. Daily feed intake a hen also increased in T2 (p<0.05). Feed conversion ratio was improved slightly without significant difference. Eggshell breaking strength and thickness were not different significantly among the treatments. Haugh unit and yolk color were also not different. Calcium and phosphorus retention in body increased in T2 (p<0.05), but dry matter and nitrogen retention were not different significantly. Differences in nitrogen and calcium excretions were not found among the treatments. But phosphorus excretion decreased in order of dietary phosphorus levels with supplement phytase compared to C (p<0.05). Tibial ash, calcium and phosphorus were similar among the treatments. In conclusion, supplemental microbial phytase in laying diet may help to utilize phytase phosphorus, and could decrease NPP intake.

  • Effects of levels of Bomboo Vinegar Liquids(BVL) on growth performance, serum profile and meat quality in employing 90 pigs were investigated. Ninety pigs were allocated into 3 groups and fed by dietary levels of BVL 0(control), 2.0 and 4.0% were included in experimental diets of each of the groups. Concentrated diet was supplemented with 2.0 and 4.0% BVL. The results showed that the daily weight gains and the feed conversion increased significantly(p<0.05) in 2.0% BVL and the feed intake increased slightly. The glucose and the cholesterol contents at the serum decreased significantly(p<0.05) in 2.0 and 4.0% BVL. On the other hand the total protein concentration and the blood urea nitrogen(BUN) increased significantly(p<0.05) in 4.0% BVL. The carcass weight increased significantly(p<0.05) in 4.0% BVL, and back fat thickness had decreased significantly(p<0.05) in 2.0 and 4.0% BVL. The carcass grade tended to increase in 2.0 and 4.0% BVL. The total fat content of loin tended to increase in 2.0 and 4.0% BVL while the cholesterol content decreased significantly(p<0.05). The pH had lower slightly in 2.0 and 4.0% BVL, the lightness and the yellowness of the meat color had higher significantly(p<0.05) while the redness decreased. Shear force values had lower significantly(p<0.05) in 2.0 and 4.0% BVL. For the fatty acid composition, the saturated fatty acids decreased significantly(p<0.05) in 2.0 and 4.0% BVL while unsaturated fatty acids(oleic acid and linoleic acid) increased significantly(p<0.05). For the sensory evaluation, 2.0 and 4.0% BVL had a significant(p<0.05) effect of diminishing the odor and improving the appearance. The taste was also significantly(p<0.05) improved. In conclusion the 2.0% BVL had a positive effect on the feeding performance, the carcass grade and the meat quality characteristics therefore 2.0% BVL is the appropriate supplemental levels of BVL for finishing pigs.

  • To quantitatively assess the effects of turbidity on egg development and larval fish survival, a laboratory fish rearing experiment was applied to different life stages (newly hatched larval stage, juvenile stage and pre-adult stage) of the Zacco platypus, one of the most universal and tolerant species in Korea. According to the stress index of turbidity in water with exposure time, three different treatments, including a reference condition (1~7 NTU) as well as intermediate (20~150 NTU) and high turbidity conditions (400~1,000 NTU) were applied, and egg hatching and larval fish mortality rates were observed. The mortality rates of newly hatched larval fish were significantly different among treatments (ANOVA, $F_{2,3}$=17.79, p<0.05). Average rates of survival to hatching were 20.9% (${\pm}0.1%$) for reference condition, 11% (${\pm}6.9%$) for intermediate level and 3.2% (${\pm}3.7%$) for high level conditions, respectively. A sudden change of mortality at the high level was observed within 5 days of the experiment. About 84% of juvenile fish survived until 20 experimental periods under conditions of reference turbidity, while survival under conditions of intermediate turbidity was over 80% of larval fish until day 13 of the experiment, but dropped to less than 10% after day 14 and 15 of two experiments. Fish mortality appeared from day 6 of the high turbidity experiment, and 50% mortality was achieved at day 9 to 10 of experiment. Full mortality occurred at day 14 of the experiment (RM-ANOVA, $F_{2,38}$, p<0.005). In the pre-adult stage experiment, no mortality was observed during the experiment at reference level treatment (20 days), while only slight mortality rates were observed for both intermediate and high levels until day 5 of the experiment, however, no further fish died in either experiment. It was significantly different compared to reference condition (RM-ANOVA, $F_{2,20}$=8.28, p<0.01), but no difference was observed between intermediate and high level conditions. Consequently, this tolerant species has been determined to be well adapted to high levels of turbidity in its adult stage, but more vulnerable throughout earlier life stages.

  • This study was conducted to estimate genetic parameters for reproductive traits using multivariate animal models in Yorkshire breed. For the study, 4,989 records for litter traits collected between the year 2001 and 2005 from Yorkshire pigs in K GGP were used. The effects of environmental factors such as farrowing year, parity, weaning to estrus interval (WEI), and suckling period were statistically significant (p<0.05), but farrowing season was not significant, for reproductive traits. The estimates genetic correlations and phenotypic correlations in total number of born and number of suckling, was shown to highly correlated. The genetic correlations were higher than phenotypic correlation. The estimates of heritabilities for reproductive traits, considering permanent environment effects (PE) were much lower than those obtained when permanent environment effects were not considered (NPE) in the model. The estimates of heritabilities were 0.240 and 0.076 for total number of born and 0.187 and 0.096 for number of suckling in NPE, and PE, respectively. These results itivcate that PE should be considered in the statistical mode to estimate more acco ate breeding values.
