  • We examined the mediating effect of the consistency of the values of organizational members on the relationship between the values of IT enterprise executives and organizational performance. Hypotheses 1, 2, and 3, which were set up to achieve the purpose of this study, were verified as follows. First, Hypothesis 1 proposed that the values of management will have a positive effect on organizational performance. Second, Hypothesis 2 proposed that the values of management are likely to have a positive effect on the consistency of the values of organizational members. Third, Hypothesis 3 proposed that the consistency of the values of organizational members will have a positive (+) influence on organizational performance. We found that the consistency of the values of organizational members has a positive (+) influence on organizational performance. Hypothesis 3 was adopted. Fourth, the consistency of the values of the organizational members proved that the organizations with high consistency of values performed well by mediating the values and organizational performance of management. In other words, according to the values of the management, we can improve an organization's sustainability management system by increasing the value of organizational performance and the values of organizational members. Therefore, we must establish plans that can be shared systematically and strategically about the values of management. In addition, the consistency of the values of organizational members has a direct or indirect influence on improving organizational performance. Therefore, we need to systematically derive and improve various factors that can increase the consistency of the values of organizational members in terms of strategic human resource management, such as organizational vision, core values, talent awards, selection process, and motivation. Therefore, the greatest significance of this study is in its theoretical and practical implications for increasing the sustainability management system by using the influence of the executives' can do to further improve the organizational performance.

  • Alzheimer's disease severely compromises cognitive function. One of the mechanisms to explain the pathology of Alzheimer's disease has been the hypotheses of amyloid-pore/channel formation by complex $A{\beta}$-aggregates. Clinical studies suggested the moderate alcohol consumption can reduces probability developing neurodegenerative pathologies. A recent report explored the ability of ethanol to disrupt the generation of complex $A{\beta}$ in vitro and reduce the toxicity in two cell lines. Molecular dynamics simulations were applied to understand how ethanol blocks the aggregation of amyloid. On the other hand, the in silico modeling showed ethanol effect over the dynamics assembling for complex $A{\beta}$-aggregates mediated by break the hydrosaline bridges between Asp 23 and Lys 28, was are key element for amyloid dimerization. The amyloid pore/ channel hypothesis has been explored only in neuronal models, however recently experiments suggested the frog oocytes such an excellent model to explore the mechanism of the amyloid pore/channel hypothesis. So, the used of frog oocytes to explored the mechanism of amyloid aggregates is new, mainly for amyloid/pore hypothesis. Therefore, this experimental model is a powerful tool to explore the mechanism implicates in the Alzheimer's disease pathology and also suggests a model to prevent the Alzheimer's disease pathology.

  • To determine the age structure of a Hynobius leechii breeding population and analyze relationships between the order of entrance to breeding ponds and physical parameters and age, we studied a wild population of the species in the Research Forests of Kangwon National University in Chuncheon, Kangwon, South Korea from March 16 to April 13, 2005. The age of breeding males ranged one to nine years old and that of females ranged from three to nine years old. The asymptotic sizes of males and females were 6.36 and 6.51 cm, respectively, and the growth coefficients of males and females were 0.71 and 0.81, respectively. The snout-vent length (SVL), head length, and body mass of males were all positively correlated with their age, but female age did not show a significant relationship with any physical parameter. The tail depth, body mass, and condition factors (SVL/body mass $\times$ 100) of both males and females were negatively related with the order of entrance to the breeding pond. The head width and SVL of males were also negatively correlated with the order of entrance, but the SVL of females was positively related with the order of entrance. These results suggest that physical parameters are more important determinants of breeding migration patterns than age. We discuss which of two hypotheses, the mate opportunity hypothesis and the susceptibility hypothesis, is better able to explain the order of entrance to breeding ponds for male and female H. leechii.

  • Background: This study was to suggest the process of making strategy for effective intervention and evaluation on functional problems of the frozen shoulder patient applied International Classification of Functioning Disability and Health (ICF) Tools. Methods: The patient was 48years old woman with right shoulder adhesive capsulitis and calcific tendinitis. In first phase, therapists could list the information relating to functional problems used by the ICF Core set and then could confirm the interaction among the problems using the ICF assessment sheet. In second phase, therapist is needed to make the hypothesis and hypothesis testing and then set a primary functional goals and therapeutic goals in detail after prioritizing the problems to be managed based on the problem list. Lastly, after setting the confirmed problems as the purpose of intervention through the hypothesis testing, therapist could do some intervention after making a plan to solve these problems. Results: This report illustrates how to apply the process based on ICF concept into physical therapy practice. The decided hypothesis and goal that are to solve the problems the client faced were remarkably meaningful. Conclusions: Clinical decision making for the most effective intervention requires that therapists use the clinical reasoning process based on ICF concept.

  • As many precedent studies have shown, most children grow receiving influence from their parents. The purpose of this study was to serve as a basis for better preventive approach by finding out the relationship between the attention-deficit hyperactivity disorder(ADHD) of elementary school children and maternal behavior characteristics. Moreover, the purpose of this study was to present basic materials for developing program of children and create good relationship between child and parents for better education. For the purposes, two hypotheses were posed. Hypothesis 1: There would be a significant disparity in maternal behavior between the ADHD group and the non-ADHD group. Hypothesis 2: The environment could have an influence on maternal behavior characteristics. The subjects in this study were 71 mothers who had children with ADHD and 69 mothers who had non-ADHD, who selected from mothers of third to sixth graders in elementary school in Kyonggi, Suwon. The instruments used for the diagnosis of ADHD was DSA-IV. The data were analyzed with ANOVA(Analysis of Variance) by SPSSWIN Program. The findings of this study were as fellows: First, Hypothesis 1 was accepted. The mothers who had ADHD children had rejective behavior characteristics in while the mothers group who had non-ADHD children had controling behavior characteristics but there was no significant difference in affectionate attitude and autonomic attitude. Second, hypothesis 2 was accepted generally. The psychological and physical environment had correlation with maternal behavior characteristics. Especially, there was a significant correlational relationship between the maternal satisfaction for their life and rejection of maternal behavior. The following conclusion could be made from the above mentioned findings. First, The maternal behavior characteristics resulted in severe ADHD for children which justified the need of proper education for mothers to care children wellbeing. Second, The environment of psychology had an influence on maternal behavior. This showed that it is essential to develope educational program and counselling system for mothers

  • The recent hypothesis about the pathophysiology of schizophrenia has been centered mainly on two theories, i.e. dopamine hypothesis and serotonin hypothesis. We investigate the correlations between plasma monoamine metabolite concentrations and clinical symptoms in schizophrenic patients. The first purpose of our study was to examine whether the plasma levels of HVA(homovanillic acid) and 5-HIAA(hydroxyindoleacetic acid) are significantly different in schizophrenics, compared to normal controls. And, with the intention of clarifying the interaction between dopaminergic system and serotoninergic system, the ratio of HVA/5-HIAA also was measured. The second purpose was whether the basal(pre-treatment) levels of these metabolites show the correlation with clinical symptoms. Finally, third purpose was whether basal HVA and 5-HIAA levels can be held as a predictor of treatment response. We used Scale for the Assessment of Positive Symptoms(SAPS) and Scale for the Assessment of Negative Symptoms(SANS) as the clinical symptom rating scales. Our results were as followed, 1) only the level of basal plasma HVA was significantly differ in schizophrenics. 5-HIAA and HVA/5-HIAA were not. 2) basal HVA showed significant correlation with SAPS score, especially delusion subscale. 3) the higher was the basal HVA level, the more improvement in clinical symptoms was observed. The basal 5-HIAA level and the HVA/5-HIAA ratio did not show any significant findings. These results support the dopamine hypothesis of schizophrenia, but fail to examine on the possible involvement of serotonin in schizophrenia.

  • There is some evidence that one of major factors to produce plantar fasciitis depends on the magnitude of the foot arch strain. The orthotics that can reduce the foot arch strain during locomotion may be effective to prevent or treat plantar fasciitis. Therefore, the purpose of this study was to investigate the effect of control condition and three types of foot orthotics on 3-dimensional foot arch strain that can produce plantar fasciitis during treadmill level and uphill walking and running. Sixteen male subjects are recruited and the arch length and height strain according to three types of foot orthotics with respect to control condition were measured by using two digital video cameras. The first hypothesis which the comfort of foot orthotics would be increased from arch pad, half length orthotics to full length orthotics was mostly accepted. It suggested that the types of the foot orthotics could be properly prescribed according foot regions that is pain or abnormal. The second hypothesis which the foot arch strain can be reduced by foot orthotics during level heel-toe walking and running and the third hypothesis which the foot arch strain can be reduced by foot orthotics during uphill heel-toe walking and running were rejected. The foot arch length and height strain during walking and running showed small and subject-specific characteristics and could not be optimal biomechanical variable to prove the overall comfort. The forth hypothesis which the foot arch strain cannot be reduced by foot orthotics during uphill toe walking and running was accepted. With the foot arch length and height strain during uphill toe walking and running the windlass mechanism suggested by Hicks can be explained successfully and excessive uphill toe walking and running can be one of cause of plantar fasciitis. The dynamic investigation on the foot arch such as walking and running should be carefully observed with integrated insights considering ligaments and foot bones as well as plantar fascia, extrinsic muscles and tendons, and intrinsic muscles and tendons.
