As the number of SNS(Weibo) users in China is growing rapidly, Chinese fashion brands are heavily dependent on SNSs as a fashion marketing communication tool. For this reason, the characteristics of SNS accounts and their influences on SNS users’ responses need to be studied. Thus, the present study aimed to investigate the influences of the characteristics of Chinese fashion brands’ SNS accounts(Weibo) on the perceived usefulness of and satisfaction with the SNS acount, and brand loyalty. Data were collected via a questionnaire survey of men and women living in Beijing or Shanghai aged from 18 to 49 with experience of SNSs(Weibo). After a pilot survey of 70 subjects, the preliminary questionnaire was revised and then translated into Chinese. The questionnaire translated into Chinese was back-translated into Korean to ensure the translation was correct. The final questionnaire was administered to 600 subjects. Exploratory and confirmatory factor analyses, reliability analysis, and structural equation model analysis were conducted for data analysis. The results of this study were as follows: Five factors were extracted for Weibo characteristics: interaction, information provision, information recency, information reliability, and information playfulness. The information reliability, information playfulness, and interaction of SNS accounts(Weibo) had significant influences on perceived usefulness. The information playfulness, information reliability, and information recency showed significant influences on satisfaction. The perceived usefulness exerted significant influences on satisfaction and brand loyalty. The satisfaction also had statistically significant influences on brand loyalty.

Microglia have multiple functions in regulating homeostasis of the central nervous system. Microglia cells have been implicated as active contributors to neuron damage in neurodegenerative disorders. In this study, medicinal plant extracts (MPEs) were used to evaluate the cell-death induction effect in microglia BV-2 cells. Among 35 MPEs tested in this study, 4 MPEs showed less than a 30% cell survival after 24 hours of incubation. These were Foeniculi Fructus, Forsythiae Fructus, Zingiberis Rhizoma and Hedera Rhombea. The concentration showed that 50% cell death (IC50) occurred with 33, 83, 67 Ed highlight: Please confirm wording, and 81 μ /ml, respectively. For further study, we chose Zingiberis Rhizoma (ZR) which showed a reasonably low IC50 value and an induction of cell death in a relatively narrow range. Western blot analysis showed that ZR-treated cells showed activation of caspase-3 and cleavage of PARP Ed highlight: When an acronym is first presented it needs to be spelled out in both dose- and time-dependent manners. However, the level of Bcl-2 and Bax were not changed by ZR-treatment in BV-2 cells. These results suggest that ZR-induced apoptosis in BV-2 cells occured through caspase-3 activation. The results also suggested that ZR may be useful in developing treatments for neurodegenerative diseases.

The purpose of the present study is to provide exercises, together with music, that are helpful for elderly people’s balancing ability, and to determine their effects in order to provide data for the promotion of elderly persons’health. Thirty elderly persons were randomly assigned to a balance training group(BTG) of 15 subjects, or a music and balance training group (music therapy + balance training [MTBTG]) of 15 subjects; intervention was implemented three times per week for six weeks. To measure the changes in their balancing ability before and after the experiment, the limit of stability, the“Timed Up and Go”(TUG) test, and the Berg Balance Scale (BBS) were measured. Changes in the limit of stability before and after the experiment were shown to be significant in both the BTG and the MTBTG. Changes in the limit of stability of the right side before and after the experiment showed statistically significant differences between the BTG and the MTBTG. Changes in the TUG test and the BBS before and after the experiment were shown to be statistically significant in both the BTG and the MTBTG. The application of music during balance training thus is considered to have a positive effect on elderly persons’balancing ability.

This study aims to compared effect of balance between general walking exercise and power walking exercise. Twenty subjects were classified into two groups, general walking exercise(n=10) and power walking exercise(n=10). As a result, two group showed difference within the group and there is significant difference between two groups. 1) In compared static balance of sway area at pre-post test to exercise group, general walking exercise group did not change significantly. however, power walking exercise group did change significantly. and At sway distance, two group showed significant changes. 2) In compared Static balance between the groups sway area and sway path at pre-post test, two group showed significant changes. 3) In compared dynamic balance of center distance at pre-post test to exercise group, general walking exercise group was no significant difference in all directions. power walking exercise group was significant difference in all directions. 4) In compared dynamic balance between the groups sway area and sway path at pre-post test, there was no significant difference in leftward, rightward, forward directions and was significant difference in backward, overall direction. Therefore, power walking exercise can be recommended promote balance.

This study aims to examine the effect of patellar taping common to patients with patellofemoral pain syndrome on the change of knee joint location. The total number of participants is 12 patients with no pain in their knee. There are three different experiments: no-taping, placebo taping, and patellar taping. After application, they squat on their hams. As a result, both the muscle activity of vastus medialis and that of vastus lateralis increased in placebo taping compared to no-taping, which wasn't statistically significant. However, the muscle activity of vastus medialis and that of vastus lateralis decreased in patellar taping compared to no-taping, which was statistically significant. This suggests that patellar taping causing the lateral attraction of knee joint is more influential to the dynamics of knee joint than skin afferent input in placebo taping. Therefore, patellar taping is effective to change the location of knee joint, affect the muscle activity of quadriceps muscle of thigh, and thus correct the misalignments of the knee joint.

The purpose of this study was to investigate the influence of handicraft activities on hand promptness and grasp in the elderly. Subjects were comprised of 14 senior citizens between the ages of 70-85, with 7 subjects in the experiment group and 7 in the control group. Subjects in the experiment group practiced various handicrafts twice a day, while those in the control group did not participate in any special activity. The Jebsen Taylor Hand Function Test was used to evaluate the results, while a dynamometer and pinch gauge were used to measure hand promptness and grasp. The 7 senior citizens in the experiment group were able to increase their hand promptness and grasping skills. Conclusively, handicrafts can help improve hand promptness and grasp in the elderly. Furthermore, the development and improvement of such skills can have a positive influence on the daily lives of senior citizens. Such skills are expected to improve the overall neuro-function in the elderly population.

The seven-spotted lady beetle, Coccinella septempunctata (Coleoptera: Coccinellidae), known also as the seven-spot ladybird, is natural enemy for aphids and has a broad ecological range, living almost anywhere there are aphids for it to eat. In order to understand the genetic diversity and geographic variation of the species we sequenced a portion of mitochondrial COI gene (658 bp) and complete nuclear internal transcribed spacer 2 (ITS2) collected from nine Korean localities. A total of 21 haplotypes (CSCOI01 ~ CSCOI21), with the maximum sequence divergence of 4.56% (30 bp) were obtained from COI gene sequence (from 78 individuals), whereas 65 sequence types (CSITS201 ~ CSITS265), with the maximum sequence divergence of 2.06% (11 positions) were obtained from ITS2 (from 79 individuals), indicating substantially larger sequence divergence in mitochondrial gene sequence. Both COI gene and ITS2 shows the distribution pattern that only a few haplotypes or sequence types are widely distributed, whereas majority of them are highly restricted in one geographic location, even represented as a single individual. Unlikely the ITS2 sequence types the mitochondrial COI haplotypes evidenced the presence of two main phylogenetic groups, reciprocally monophyletic to each other. Geographically, these two groups are spread in all localities surveyed. Considering both COI gene and ITS2 sequence together, current our data may suggest the presence of ancestral polymorphism, rather than on-going speciation, but more scrutinized analysis will be performed soon. Due partially by the presence of both COI groups in all surveyed localities, the genetic diversity estimates of all localities are similar from the perspective of COI gene, but ITS data showed extremely lower genetic diversity of one islet locality, Anmyeon-do (locality 2; 0.002530 vs. 0.008054 ~ 0.012060). Analysis of gene flew estimates between localities indicates that most populations are highly interconnected to each other. However, one islet locality, Anmyeon-do (locality) has shown statistically significant distance from the remaining localities on the basis of only ITS2 data (FST = 0.19 ~ 0.34), requiring scrutinized phylogeographic inference on this population with expanded sampling. As more scrutinized analysis is performed, further fruitful inference on the geographic contour of the species might be available.
