  • Paraproteinemia is caused by a proliferation of monoclonal plasma cells or B lymphocytes. Approximately 10% of idiopathic neuropathies are associated with paraproteinemia, where a certain paraprotein acts like an antibody targeted at constituents of myelin or axolemma in peripheral nerves. The relationship between paraproteinemia and peripheral neuropathy remains unclear despite this being of interest for a long time. Neurologists frequently find paraproteinemia during laboratory examinations of patients presenting with peripheral neuropathy, especially in the elderly. The possibility of a relationship with paraproteinemia should be considered in cases without an explainable cause. We review the causal association between paraproteinemia and neuropathy as well as clinical, laboratory, and electrophysiologic features, and the treatment options for paraproteinemic neuropathy.

  • The objective of the study is to verify the discriminatory power of valuation indexes in predicting IT small and medium sized manufacturing firms' going concern or firms' failure. The result of the study is expected to be useful in loan evaluation, investment decision, internal management decision making and business improvement. The results of study is as follows. First, we find that at least six valuation index elements are significant ex-ante variable which are discriminating between firms' going concern and firms' failure in IT small and medium sized manufacturing firms in various analysis' results. Second, these index elements are composed of 2 indexes-the ability of technology R&D, the efficient strategy of market penetration and six index elements explain 46% of the total variance. This explainable power of these indexed is similar to that of the existing 16 index elements. Finally, we find that the most important success factor of IT small and medium sized manufacturing firms are the ability of technology R&D and the efficient strategy of market penetration.

  • The growth of Internet usage even accelerated by the spread of high-speed Internet access network such as ADSI is affecting our socioeconomic activities and culture in a great way. Korea is recently reported to be the number one high-speed Internet network subscription per 100 people in the world. In a way to reflect this situation, we collect a moderate size of sample proportional to the population of each region across country and investigate what factors might explain the level of user's dissatisfaction with respect to Internet service they have been receiving. The results indicate that the set of gender, age, Internet usage, service kinds, incoming e-mails, and e-shopping is significantly influencing user's dissatisfaction, in that dissatisfaction is measured in 11 perspectives. In particular, user's age, gender, and e-shopping experiences are considered to be mostly explainable.

  • In this paper, we work with steel circular tubes and propose analysis model which can consider local buckling that it has an effect on failure of steel structures and induce the relation between loading and deformation. First of all, in respect to axial symmetry local buckling, which is simplest case, elasto-plastic behavior acting only axial loads is object Therefore, it suggests analysis model for axial symmetry local buckling. And that is explainable the process from increasing internal force to decreasing passing maximum internal force. Besides, we induce the relation between the axial force and axial deformation.

  • The properites of Zn-diffusion in III-V ternary alloy semiconductor $In_{1-x}Ga_{x}p$, which was grown by the temperature gradient solution (TGS) method, have been investigated. The composition, x, dependence of the Zn-diffusion coefficient at $850^{\circ}C$ and the activation energy for Zn-diffusion into $In_{1-x}Ga_{x}p$ were found to be $D850^{\circ}C$(x)= $3.935{\times}10^{-8}exp(-6.84{\cdot}x)$, and $E_{A}(x)=1,28+2,38{\cdot}x$, respectively. From this study, we confirm that the Zn-diffusion in $In_{1-x}Ga_{x}p$ was explainable with the diffusion mechanisms of the interstitial-substitutional, which was widely accepted mechanisms in the III-V binary semiconductors.

  • The purpose of this study was to investigate methodological and theoretical problems in measuring the acquisition of national identity of in-country and over-seas Korean adolescents. The subjects consisted of 574 incountry and overseas (Chinese, Russia and Japan) Korean adolescents (total 509), 15 to 25 years of age. Data were collected with the use of a questionaire, the Scale of National Identity. The results were that (1) the concept of national identity was organized on two dimensions (cognitive vs. sociocultural). The former consisted of 6 cognitive characteristics (uniqueness, sameness, continuity, acceptability, respectability and royalty). The sociocultural dimension consisted of the cognition of 7 sociocultural characteristics (history, norm, fraternity, symbol, consanguinity, Korean language and nationality). Except for consanguinity, there was a close relationship within each and between the 6 cognitive characteristics. Also there was a close relationship within each and between the 7 sociocultural characteristics of national identity. (2) Some demographic variables, such as age of respondents, place of birth and level of understanding of Korean language contributed to acquisition of national identity. (3) Among several demographic variables, nationality was the most explainable.

  • Metal-insulator type, nano-granular soft magnetic films have been reviewed from the viewpoint of high frequency magnetic materials. The formation of nano-granular structure is related to the magnitude of heat of formation of intergranule materials. Variation of the ratio of granule phase to intergranule phase in the film is found to produce various characteristics in the magnetic properties of the film. The HRTEM observation reveals that neighboring granules in the film with above 60 at.% Co, contact at considerable points and the films show soft magnetic properties which are explainable in terms of the random anisotropy model for nano-crystalline materials. Addition of Ni group elements in Co-O based films enhances their anisotropy field up to 400 Oe and they exhibit excellent frequency response of permeability. Also, large electromagnetic noise suppression effect is demonstrated as one of their potential applications.

  • Providing the reasonable construction cost at the initial stage of the rural development project, is a kety factor of the each step of project , such as propriety analysis , cost planning , design, and planning the progress of work. The explainable construction cost can be estimated at the early stage using the actual cost data by statistical analysis. In this study, the influence factors are extracted by factor analysis with the actual cost data of rural development project, object cost model is developed by multiple regression analysis, and verify the developed cost model by Monte-Carlo simulation .

  • The stability and the electronic structure of $In_0.5$.$Ga_0.5$P-based superlattices are examined through self-consistent ab initio pseudopotential calculations. A chalcopyrite-like structure is found to be the lowest energy state over (001) and (111) monolayer superlattices (MLS). Our calculations indicate that all the ordered structures in bulk form are unstable against phase segregation into binary constituents at T = 0 while for epitaxial growth, the chalcopyrite phase is stabilized. The fundamental band gaps of the ordered structures are found to be direct and smaller than that of disordered alloys. The lowering of the band gap is explainable by band folding and pushing effects. We find the reduction of the band gap to be largest for the (111) MLS.

  • In an English multiple Wh-construction with two wh-words, only a higher-located wh-word in a sentence structure is allowed to pre-pose to the Spec of CP, which has been known as a Superiority Effect(SE). Contrary to English, Korean and Japanese have been known not to respect SE, and this phenomenon has been called an Anti-Superiority Effect(ASE). Recent studies including Takita et al(2007) and Harada(2015) among others, however, have suggested exceptional cases to ASE in Japanese, and attempted to explain them through a feature checking mechanism within the Minimalist Program(MP) by Chomsky(1995, 1998). Such explanations of MP, which are based on the abstract feature checking system, have recently been considered just as a kind of technicalia and should be backed up with further empirical evidence. In this paper, I show that there are also exceptions to ASE in Korean, and the exceptional cases to ASE both in Korean and Japanese can be well explainable based on the empirical evidence of Korean/Japanese morpho-syntax.
