        Feral cats are widely considered to be leading the potential impacts on public health. This study aimed to provide estimates of vital data for feral cats relating Trap-Neuter-Return (TNR) to establish strategies effectively to manage feral cats in Pyeongtaek. Thus, this study focused on estimating feral cat population in Pyeongtaek and conducted a comparative analysis of the data for feral cats in Seoul (2013). The number of feral cats was estimated from 23,069 to 26,655 in Pyeongtaek, 2019. In relation to human population, when comparing the number of feral cats of Pyeongtaek and Seoul, it ranged from 4.57% to 5.28%, and from 1.97% to 2.55% respectively. This showed that Pyeongtaek was higher than Seoul. Fewer kittens were found in high-density areas, which the TNR project is believed to be generally effective in controlling the number of feral cats. In conclusion, in urban and rural complexes such as Pyeongtaek City, the number of feral cats compared to the population was higher than that of Seoul City, and the TNR program is believed to be somewhat effective in controlling the number of feral cats. When implementing TNR, it is necessary periodically to investigate the population and reflect them in policymaking.

        Japanese pine sawyer beetle, Monochamus alternatus Hope (Coleoptera: Cerambycidae) is considered as a serious pest in pine trees. To develop an eco-friendly strategy to manage this forest insect, we collected entomopathogenic fungi from Korean soil and assessed their virulence against the adults of the insect in laboratory conditions. As a result, two isolates with conidial suspension (1.0×107conidia/ml), showed 87% and 90% mortality 12 days after fungal treatment, respectively. We assessed the potential of the fungi-derived destruxin and protease as additives to the fungal isolates, and they showed insecticidal activity via feeding and spraying treatments. Finally, we produced fungal conidia in massive solid cultures and formulated wettable powders, and now studying optimal conditions of oil-based formulation with two isolates. Based on these results, we are evaluating the control efficacy of the fungal agents against M. alternatus in field conditions.

        To elucidate the effect of cellular phone electromagnetic wave (EMW) exposure on the developing cerebellar cortex of neonatal Sprague-Dawley rats, animals were exposed to cellular phone electromagnetic waves for 1 hr per day for 3 weeks. At the end of the experimental period, animals were sacrificed by cardiac perfusion, after which histological samples were prepared and observed microscopically. In the EMW exposure group, external granule cells were remained partially in the external granular layer without migrating into the internal granular layer. In addition, dark stained shrunken Purkinje cells with pyknotic nuclei increased and the outline of cells became irregular and showed degenerative signs, such as mitochondrial swelling and disrupted cristae. Moreover, the cisternae of rough endoplasmic reticula and Golgi complex were severely swollen. Bergmann glial cells adjacent to the dark stained Purkinje cells were swollen and cytoplasmic organelles were scant. Dark stained shrunken granule cells were also observed and the outline of cells was irregular. The results of the present study suggest that cellular phone EMW exposure to neonatal Sprague-Dawley rats leads to a partial delay of early migration of cerebellar cortical cells and degenerative changes in Purkinje cells, Bergmann glial cells and granule cells.

        Xenotransplantation is proposed as a solution to the problem of organ shortage. However, transplantation of xenogeneic organs induces an antigen-antibody reaction in α-1,3-gal structure that are not present in humans and primates, and thus complement is also activated and organs die within minutes or hours. In this study, we used FasL gene, which is involved in the immune response of NK cell, and US11, which suppresses MHC Class I cell membrane surface expression, to inhibit cell mediated rejection in the interspecific immunity rejection, and also hDAF(CD55) was introduced to confirm the response to C3 complement. These genes were tranfeced into Korean native pig fetal fibroblasts using pCAGGS vector. And cytotoxicity of NK cell and human complement was confirmed in each cell line. The US11 inhibited the cytotoxicity of NK cell and, in addition, the simultaneous expression of US11 and Fas ligand showed excellent suppress to T-lymphocyte cytotoxicity, hDAF showed weak resistance to cytotoxicity of natural killer cell but not in CD8+ CTLs. Cytotoxicity study with human complement showed that hDAF was effective for reducing complement reaction. In this studies have demonstrated that each gene is effective in reducing immune rejection.

        Introduction E-retailers take advantage of apparel products which are viewed as a constantly changing experiential product rich that lead to various kinds of hedonic consumption, like impulse buying (Park and Kim, 2008). Apparel purchases are often affected by irrational and emotional attraction making them one of the most frequent impulsively purchased items online (Rhee, 2007). The e-shoppers are more spontaneous due to marketing stimuli which makes it easier to purchase impulsively and reduces risk aversion (Madhavaram and Laverie, 2004). In fact, shoppers are more likely to overspend when e-shopping because it does not feel like spending money (Dittmar, Long, and Meek, 2004). Apparel retailers need to pay special attention to converting web browsers to impulse purchasers—a capability that plays an important role in the growth of e-business. Despite the vast amount of data available online, few efforts have been made to identify the relationship among services attributes, browsing, urges to buy, and e-impulse buying of apparel products. This study explores a model of e-impulse buying for strategic e-business management in apparel products by understanding critical factors of e-store service attributes over the shopping websites and its impact on browsing and urges to buy for apparel in Korea. Specifically, the objectives of this study were to (a) identify underlying factors of online service attributes related to apparel products; (b) estimate structural equation model for causative relationship among service attributes, browsing, urges to buy, and e-impulse buying; and (c) examine mediating effect of browsing and urges to buy on e-impulse buying for apparel. By focusing on apparel products, this study will shed light on complex issues surrounding online service and provide opportunities for strategic development and promotion in fashion merchandising online. Also, this study could help mangers to identify successful global applications of e-marketing for apparel products. Methods A self-administered questionnaire was developed based on previous literatures. The instrument consisted of the main variables; e-service attributes of apparel stores, browsing, urge to buy, and e-impulse buying of apparel products. Participants responded to questions on a 5-point rating scale (1=very unlikely to 5=very likely). The questionnaire was administered during a regularly scheduled class in universities. Usable data were obtained from 319 students aged between 18 and 25 residing at the metropolitan areas in Korea. More than half of the respondents (65.5%) were 18 to 21 years old. Nearly 65.5 percent of the subjects were women, and more than half of the respondents (63.8%) were below the sophomore. For data analysis, exploratory factor analysis with varimax rotation was conducted to determine dimensions of perceived service attributes of the apparel online store. Cronbach's alpha established inter-item reliability between items. The structural equation model analysis was conducted by AMOS 18.0 using a correlation matrix with maximum likelihood approach. The overall fit of the model was assessed by various statistic indexes: chi-square (χ2), goodness of fit index (GFI), adjusted goodness of fit index (AGFI), and root mean squared residual (RMR). Results An exploratory factor analysis revealed three types of e-store service attributes: Ease of Use, Accuracy, and Reliability. The structural equation model, which was estimated to examine causal relationships among variables (i.e. three types of service attributes, browsing, urges to buy, and e-impulse buying), was relatively acceptable (chi-square value = 168.23, df = 157, p = .026; GFI = .95, AGFI = .93, RMR = .05). The model demonstrated that the two factors of service attributes (i.e. ease of use, accuracy of service) were significant variables to influence the browsing, which influence the urges to buy and e-impulse buying for apparel stores. E-impulse buying of apparel products was influenced by browsing and urges to buy. In addition, the urges to buy and browsing mediated the casual relationship between service attributes and e-impulse buying for apparel products. This result suggests that browsing and urges to buy perceived by shoppers were important predicting e-impulse buying of apparel products. Especially, urges to buy apparel products was the most important mediator to trigger e-impulse buying of apparels. Conclusions & Implication This study explores a structural equation model for understanding e-impulse buying in conjunction with browsing, urges to buy and service attributes of apparel store perceived by shoppers in Korea. The findings suggest that the browsing and urges to buy perceived by shoppers play important roles as mediators of the e-impulse buying for apparel stores. Especially, service attributes of apparel e-store perceived by shoppers had indirect effects on e-impulse buying through the browsing and urges to buy, implying that the consumers perceived the ease to use of e-store was the more browsing at e-store and then the more perceiving the urges to buy apparel products. However, the more browsing at apparel e-store was the less the e-impulse buying of apparel products and the more perceiving urges to buy at e-store is the more e-impulse buying of apparel products. This study provides retail managerial implications for stimulating e-shoppers' impulse buying of apparel products. They could increase shoppers' unplanned purchases by developing the service program for convenience (e.g. easy to use the structure of contents, wide ranges of products/service packages, various menu options of website) to stimulate the browsing at e-store.

        The purpose of this study was to analysis of the effect of proprioceptor training and vestibular organ training for balance ability. The subjects was consist of two different subjects group, proprioceptor training group and vestibular organ training group. Proprioceptor training group consisted of 10 subjects and vestibular organ training group consisted of 10 subjects. Training was performed 3 times per week, 30 minutes per day, for 3 weeks. Balance ability analysis was performed using Romberg's one leg standing test and BT4 when opened eyes and closed eyes. The analysis results were as follows. There was no significant differences in balance after the training in both groups when they opened their eyes(p<.05). But there was significant differences in balance after the training in both groups when they closed their eyes(p<.05). And there was no significant difference in balance after the training between the proprioceptor training group and the vestibular organ training group when they closed their eyes(p<.05). Given the above results, proprioceptor training and vestibular organ training enhanced balance but there was no significant difference between the two methods.

        The fact that flip-flops, one of many different types of unstable shoes, are light and relatively easy to put on, accounts for their popularity among people. But because flip-flops rely heavily on the support of a single thong between your first and second toes, they impose a huge amount of pressure onto lower leg. Thus in the following experiment we tried to examine the different effects of flip-flops and running shoes in terms of their effect on muscle activity and fatigue of tibialis anterior and gastrocnemius during walking. In order to measure an electromyogram we used Free EMG system. 10 men and 10 women in running shoes ran on treadmills for 15 minutes at 4.8km/h, 2 days later the same experiment was carried out, but this time, in flip-flops. p value turned out to be greater than .05 and thus there was no considerable difference between the effects of flip-flops and running shoes on muscle activity and fatigue during walking. Therefore we conclude that despite the fact that flip-flops are considered unstable, their effects on muscle activity and fatigue of tibialis anterior and gastrocnemius are negligible.

        The purpose of this study was to investigate spirometric lung pattern, respiratory function and degree of fatigue by lung function tests and fatigue tests of 39 elderly people in a care facility aged 65 and over. The respiratory function tests were used to the Spirovit SP-1 and fatigue tests were used modified Piper fatigue scale(mPFS). Regarding the respiratory function, the FVC was 1.41±0.36ℓ, the FVC % predicted was 69.10±14.98%, the FEV1 was 1.02±0.31ℓ, the FEV1 % predicted was 63.27±16.05%, the FEV1/FVC was 72.77±13.40%, and the fatigue score was 5.83±1.09. As for the spirometric lung pattern, 19 patients had a restrictive pattern(48.7%), followed by 11 with a mixed pattern(28.2%), 5 with an obstructive pattern( 12.8%), and 4 with a normal pattern(10.3%). Regarding the respiratory function and fatigue by spirometric lung pattern, the FVC and the FVC % predicted of patients with a normal pattern or an obstructive pattern were greater than other groups at a statistically significant level. As for the FEV1, that of patients with a normal pattern was significantly higher than others, and for the FEV1 % predicted, that of patients with a normal pattern or a restrictive pattern was significantly higher(p<.001). Fatigue score by patients with a normal pattern was significantly less than patients of other patterns(p<.001). Therefore, pulmonary physical therapy is considered necessary to improve respiratory function and fatigue degradation of elderly in a facility.

        In the present study, we investigated the effect of porcine follicular fluid (PFF) concentration (10% vs. 1%) and protein-free media (PFF 0%) on maturation of porcine oocytes in vitro and analysed difference in gene expression in resulting blastocysts following parthenogenetic activation. Three groups were tested; 1) 10% PFF: Tissue culture medium (TCM) 199+10% PFF; 2) 1% PFF: TCM 199+1% PFF; and 3) 0.1% PVA: TCM 199+0.1 PVA. Cumulus-oocyte-complexes were cultured in the respective media containing gonadotrophin (1 ug/ml), epidermal growth factor (10 ng/ml), cystein (0.57 mM), sodium pyruvate (0.91 mM), insulin (5 ug/ml), 9-cis retinoic acid (5 nM) for 20~22 h and then without hormonal supplements for an additional 20-22 h. Data was analyzed using statistical analysis system(SAS) program. There was no significant difference in oocyte maturation rate. However, significantly higher (p<0.05) proportions of embryos developed to the blastocyst stage when oocytes were matured in 10% PFF group (45%) than in the 1% PFF group (31.1%). The total cell numbers were not significantly different among groups (52 ± 1.3 vs. 54.6±3.1 vs. 54.4±2.5, respectively). The relative abundance (ratio to beta-actin mRNA) of gene transcripts related to apoptosis in blastocysts was measured by real- time PCR. The expression of anti-apoptotic gene (BclxL) was up-regulated and the expression of pro-apoptotic gene (Bax) was down-regulated in 10% PFF group than in the other groups. Therefore, it can be concluded that supplementation of 10% PFF during in vitro maturation improves embryo development by reduction of apoptosis. * This study was supported by IPET (#311011-05-1-SB010), RNL Bio (#550-20120006), MKE (#10033839-2011-13), Institute for Veterinary Science, the BK21 program and TS Corporation.
