  • The reactionary responses to control human standing dynamics were estimated under the assumption that postural complexity mainly occurs in the mid-sagittal plane. During the experiment, the subject was exposed to continuous horizontal perturbation. The ankle and hip joint rotations of the subject mainly contributed to maintaining standing postural control. The designed mobile platform generated anterior/posterior (AP) motion. Non-predictive random translation was used as input for the system. The mean acceleration generated by the platform was measured as $0.44m/s^2$. The measured data were analyzed in the frequency domain by the coherence function and the frequency response function to estimate its dynamic responses. The significant correlation found between the input and output of the postural control system. The frequency response function revealed prominent resonant peaks within its frequency spectrum and magnitude. Subjects behaved as a non-rigid two link inverted pendulum. The analyzed data are consistent with the outcome hypothesized for this study.

  • Internalizing and externalizing behavior problems may be more common in children with disability families but rarely known is the magnitude of the problem and the risk factors compared to those in children with non-disability families. This study was undertaken to examine if socio-economic factors, parental health, and family functioning affect children's internalizing and externalizing behaviors differently between two comparison groups. The research literature on childhood behaviors was briefly reviewed. The data was derived from the Mental Health of Children and Young People in Great Britain, 2004. Regression analyses provide evidence that the family type, economic status, and income level are uniquely associated with an increased risks of internalizing or externalizing behavior problems in children with disability families, whereas sex, age, family size, parental health, and family functioning factors have similar impacts on the child's internalizing or externalizing variances between two groups. Intervention is desirable to address the concerns influencing internalizing and externalizing performances among children with disability or non-disability families.

  • Ferroptosis is a newly recognized type of cell death that results from iron-dependent lipid peroxidation and is different from other types of cell death, such as apoptosis, necrosis, and autophagic cell death. This type of cell death is characterized by mitochondrial shrinkage with an increased mitochondrial membrane density and outer mitochondrial membrane rupture. Ferroptosis can be induced by a loss of activity of system $X_c{^-}$ and the inhibition of glutathione peroxidase 4, followed by the accumulation of lipid reactive oxygen species (ROS). In addition, inactivation of the mevalonate and transsulfuration pathways is involved in the induction of ferroptosis. Moreover, nicotinamide adenine dinucleotide phosphate oxidase and p53 promote ferroptosis by increasing ROS production, while heat shock protein beta-1 and nuclear factor erythroid 2-related factor 2 inhibit ferroptosis by reducing iron uptake. This article outlines the molecular mechanisms and signaling pathways of ferroptosis regulation, and explains the roles of ferroptosis in human disease.

  • The genus Vibrio contains some of the most important intestinal pathogens of humans, including Vibrio cholerae, the cause of epidemic Asiatic cholera. A group of organisms which have been reffered to as the non-agglutinating vibrio (NAG) do not agglutinate in the Vibrio cholerae 0 group 1 antisera, but are indistinguishable from the 0-1 group both chemically and genetically. Non-O-l Vibrio cholerae can cause isolated as well as focal outbreaks of diarrhea, but the volume of fluid loss does not approach that of classic cholera, and the disease is usually self-limiting. These free-living organisms are found world-widely distributed in the environment including sewage, contaminated water, estuaries, seafood and animals. These strains involved in several cases were isolated from the environment and some patients of diarrhea, and a few epidemiologic reports indicated the wide distribution of the strains throughout the country, giving an attention to the role the organisms may play in an outbreak of diarrhea in Korea. More research on the epidemiology, serologic typing and virulence of the group of organisms, should be, therefore, done to obtain a complete understanding of their role in human disease.

  • The purpose of this study was to find out the necessary conditions and factors what effect as a society member through the students with disabilities to have a positive and mutual peer relationship with their classmates in the school and by them analyzed formation process and elucidate signification. The research method focused on the data summarized and enumerated through the investigation methods such as two in-depth interviews and two observation activities part, and the data which are commonly stated or observed in the data. The results of this study start that the factors of peer relationship formation between children with disabilities and their with non-disabled children are caused by lack of prejudice or lack of awareness. However, continuous cognizance improvement program, teacher's education guidance, the age have presence sense and subject about friend equating idea was mainly shown of school education or local community.

  • The objective of present study is to obtain information on the stenosis effects in the branch tubes for industrial piping system and atherogenesis processing in human arteries. Numerical solutions for flows of Newtonian and non-Newtonian fluids in the branch tubes are obtained by the finite volume method. Centerline velocity and pressure along the bifurcated tubes for water, blood and aqueous Separan AP-273 solution are computed and the numerical results of blood and the Separan solution are compared with those of water. Flow phenomena in the stenosed branch tubes are discussed extensively and predicted effectively. The effects of stenosis on the pressure loss coefficients are determined.

  • Group level discriminations are observed in employment relations and other transactions in the form of residential occupational and production segregation and differential treatments. Recent developments in the rational theories of discrimination both on the market level and the non-market level are reviewed in terms of their relative strengths, weaknesses and complementarities. Taste discrimination could remain much suppressed in the market but could effect much chain reaction through various ways of statistical discrimination, price discrimination, human capital investment and segregation. Taste discrimination could also take the more structured form of co-workers' requiring compensation for reduced productivity due to increasing interactions with members of different language and culture in a non-segregative system. If could also be viewed in the framework of brand learning models. Non-market models of discrimination are seen to be an essential part to explain extended modes of discrimination.

  • The effect of learning orientation on company innovation and innovation capability are explored based on survey data collected from 154 small and medium-sized manufacturing firms. The theoretical links between learning orientation and company innovation as well as innovation capability are investigated in four research models that compare textile and non-textile manufacturing firms. Learning orientation has a significant effect on company innovation and innovation capability in the model test. However, some of the three segmented factors (commitment to learning, shared vision, and open-mindedness) of learning orientation had no significant effect on company innovation and innovation capability. Company innovation and innovation capability of textile manufacturing firms are predicted by the commitment to learning and shared vision, whereas those of non-textile firms were determined by shared vision and open-mindedness. Differences show that firms may need to put weight on some distinctive aspects of learning orientation according to the business categories in order to enhance company innovation.

  • The study used 24 clothing salespersons who had turnover experiences. It used a qualitative research method, through which the following turnover motives were found. The turnover motives can be classified into two: voluntary and non-voluntary. The voluntary turnover motives include marriage, career change, wages, human relationship, family moving, study abroad, health problems, and so forth. This study finds that some salespersons made a turnover because they did not like the products and brand or they preferred another products and brand. This kind of turnover is unique in the field of clothing sales and seldom found in the motives of salesperson turnover in other fields. The non-voluntary turnover motives are caused by non-personal, circumstantial factors which include the bankruptcy of companies due to economic depression, withdrawal of salesroom from department stores due to low sales, etc. This means that the creation, rise, and fall of fashion brands are closely related to frequent turnover of clothing sale associates. As there are various motives for the salesperson turnover, so it is necessary for the clothing industry to examine and investigate the trends of its salespersons and establish an appropriate policy to cope with the matter.
