  • It is difficult to make an accurate estimate of the economic value and effects on societal economy of Nano-technologies. This research measures an economic value of Nano-technologies quantitatively and analyzes its influences on societal economy. This paper chooses some major industries as analysis targets and adapts the DEFRA comparative methodology model which has been developed in the UK and recommended by OECD. For this reason, some industries which are in range of economic value assessment were investigated and related data were collected. Also, the economic value and societal influences of Nano-technologies were calculated, through the procedure of the model. In addition, this study conducts a questionnaire to experts for the validity of measurement results and procedures. This paper suggests a guideline for economic value and effects on societal economy of Nano-technologies assessments through quantitative Defra comparative methodologies.

  • This study was undertaken to explore the antecedent factors and process of the treatment-seeking behaviors of medical and alternative treatments in patients with arthritis using methodological triangulation. The data were collected from 995 arthritic patients who were registered either in a center of rheumatology for medical treatment or residents of community having no treatment to classify different treatment patterns. Sixteen patients with various types of treatment only, alternative treatment only, and no treatment were selected among the total samples to identify the antecedent factors through in-depth interview. The quantitative data were analyzed by percentile, t-test, chi-square test and discrimant analysis using SAS PC program, while the qualitative data were analyzed by means of grounded theory methodology. Treatment-seeking behaviors of patients change from the early stage to the sick-role stage. At the early stage, initial characteristics of pain and acculturation of medical professionalism affect the choice of treatment patterns. The acculturation of medical professionalism is affected by health care accessibility, level of education, duration of sickness and lay referral system. At the sick-role stage, lay referral system and acculturation of medical professionalism affect the choice of treatment patterns. The acculturation of medical professionalism is affected by characteristics of symtoms, perceived treatment effects, perceived causes of diseases and socio-economic status as well as health care accessibility, level of education and lay referral system. In conclusion, different factors as well as common factors are influencing the treatment-seeking behaviors depending on the disease and treatment stages. More detailed further studies are required to explore the value system or medical acculturation of patients which is one of the most important factors in decision-making about treatment modalities.

  • In the software development process, various development product are made in each phase of lifecycle. Formless software is visualized by products, and quality management is implemented by management for products. But, because standardization for products which is made in the development process is not established practically, developers use different development methodologies or documentation specifications. Therefore the reality is that quality evaluation is not implemented along standardized methodology or systematic process. In this paper, we constructed quality management system and designed and implemented analysis phase quality evaluation toolkit. We constructed quality external and internal character to evaluate software quality for quality management and constructed relational metrics and system of qualitative quantitative evaluation element items and, under these systems, we constructed quality evaluation toolkit and Implemented functions and evaluated products.

  • The elementary idea of 'function-words' in Classical Chinese originates from Han dynasty. But because of the pictographic nature the methodology for 'content words' had been applied to the study on 'function words', ane the conditions had not changed until modern times. In grammar functions of the function-word syntactical, morphological in unit sentence were studied in this using the method of quantitative analysis for all the function-words appeared in ${\ll}$Hwang je nae gyung-Somun${\gg}$. In the previous studies about function word, many data were collected and analyzed diachronically. But those studies failed to examine function-words closed in connection with synchronic study. Besides, in the explain about relevant function-words also, the case which was made centering around exegetic explain was most. And in the case to explain the function-words have in unit sentence also, the explain only about some function-words is made, but the analysis about concrete function to have in syntactical system is being handled negligently. This study stands not only on the background df the traditional studies but also on the basis of the western grammar and linguistics, especially the descriptive grammar and linguistics, especially the descriptive grammar. ${\ll}$Hwang je nae gyung-Somun${\gg}$ is collect and recorded the mythology and special contents related to Daoism in the side of contents as what was written on the basis of the historical consciousness of individual in contents regardless of compilation system. The purpose of this study is to clarify how the role and function of fuction-words are being made in the composition of unit sentence which appeard in ${\ll}$Hwang je nae gyung-Somun${\gg}$ through synchronic grammar system.

  • It is essential suity management and standardized asset analysis for telecommunication networks, however existing risk analysis methods and tools are not enough to give shape of the method to evaluate value and asset. they only support asset classification schemes. Moreover, since the existing asset classification schemes are to evaluate comprehensive general risk, they are not appropriate for being applied telecommunication networks and they can´t offer any solutions to an evaluator´s subjectivity problem. In this paper, to solve these problems, we introduce the standardized definition of asset evaluation model new asset classification scheme, two-dimensional asset process classification scheme to consider business process and asset, various evaluation standards for quantitative value and qualitative evaluation. To settle an valuator´s subjectivity problem, we proposed $\beta$-distribution Delphi method.

  • Background: Workers may be exposed to various types of occupational hazards at the same time, potentially increasing the risk of adverse health outcomes. The aim of this review was to analyze the effects of multiple occupational exposures and coexposures to chemical, biomechanical, and physical hazards on adverse health outcomes among agricultural workers. Methods: Articles published in English between 1990 and 2015 were identified using five popular databases and two complementary sources. The quality of the included publications was assessed using the methodology developed by the Effective Public Health Practice Project assessment tool for quantitative studies. Results: Fifteen articles were included in the review. Multiple chemical exposures were significantly associated with an increased risk of respiratory diseases, cancer, and DNA and cytogenetic damage. Multiple physical exposures seemed to increase the risk of hearing loss, whereas coexposures to physical and biomechanical hazards were associated with an increased risk of musculoskeletal disorders among agricultural workers. Conclusion: Few studies have explored the impact of multiple occupational exposures on the health of agricultural workers. A very limited number of studies have investigated the effect of coexposures among biomechanical, physical, and chemical hazards on occupational health, which indicates a need for further research in this area.

  • Recently, interest in HCI has increased domestically among the workers in the Internet business as Internet has entered into its maturing stage in which the focus has been moved from quantitative expansion of web sites to qualitative improvement. However, answering questions like "how HCI can optimize user experience, generally accepted as the ultimate goal of Internet service" seem still difficult to achieve, because the theories and research methodology of HCI has not been well informed to the Internet-related workers. For HCI to set ground in the actual business sector, its value should be translated into financial terms and the top management should be persuaded to support it. This paper deals with what benefits HCI can give to the Internet companies, how HCI can help user interface design with its research findings, what kind of research method can be applied in the business sector with actual examples.

  • Ortho-photos provide valuable spatial and spectral information for various Geographic Information System (GIS) and mapping applications. The absence of relief displacement and the uniform scale in ortho-photos enable interested users to measure distances, compute areas, derive geographic locations, and quantify changes. Differential rectification has traditionally been used for ortho-photo generation. However, differential rectification produces serious problems (in the form of ghost images) when dealing with large scale imagery over urban areas. To avoid these artifacts, true ortho-photo generation techniques have been devised to remove ghost images through visibility analysis and occlusion detection. So far, the Z-buffer method has been one of the most popular methods for true ortho-photo generation. However, it is quite sensitive to the relationship between the cell size of the Digital Surface Model (DSM) and the Ground Sampling Distance (GSD) of the imaging sensor. Another critical issue of true ortho-photo generation using high resolution satellite imagery is the scan line search. In other words, the perspective center corresponding to each ground point should be identified since we are dealing with a line camera. This paper introduces alternative methodology for true ortho-photo generation that circumvents the drawbacks of the Z-buffer technique and the existing scan line search methods. The experiments using real data are carried out while comparing the performance of the proposed and the existing methods through qualitative and quantitative evaluations and computational efficiency. The experimental analysis proved that the proposed method provided the best success ratio of the occlusion detection and had reasonable processing time compared to all other true ortho-photo generation methods tested in this paper.
