This study was designed to provide basic information for an effective wetland design by analyzing the correlation between wetland size and water quality improvement effect in regard to an artificial wetland inside the Biopark Basin by means of applying the modelling technique. It is expected that this study will contribute to a rational design, operation and management of the artificial wetland in the basin. The following conclusions are obtained through the results and discussion of this study. The results of respective design scenarios that expanded the size of the artificial wetlands in the range of 0-100 % showed that when the wetland is 'expanded 75 % compared with the existing size', water quality improved best compared with the design criteria of 'the current operation of the existing size'. The improved data are: 66.7 % in BOD5, 69.9 % in TSS, 64.7 % in T-N, 85.5 % in T-P and 51.8 % in Chl-a. In particular, with the exception of Chl-a, water quality improvement stood out in the quality items in summer among the four seasons. And that there in no direct relationship between facility scale and water quality improvement.

Purpose: This study was done to describe the research trend of Complementary and Alternative Medicine(CAM) in Korea and internationally. Method: A Systematic review of CAM related literature published from 2000 to 2005 was done. A comprehensive search by using 34 CAM modalities as search terms to identify all articles dealing with CAM was undertaken from 4 databases: PubMed, RICHIS, KoreaMed, and Riss4U. A Total of 588 abstracts and 223 original articles were reviewed by two independent reviewers using systematic analysis guidelines. Data regarding the types of study design, characteristics of subjects and researchers, and classification of CAM modalities was recorded. The outcome measures of CAM were identified. Results: CAM research has been rapidly increasing worldwide in the last decade. In Korea, nursing(53.5%) followed by medicine(42.7%) occupied the majority of CAM research in comparison to medicine(42.9%) and disciplines in CAM(25.0%), like homeopathy, internationally. Prevailing research designs in Korea were experimental and quasi-experimental, however, randomized clinical trials were found. Internationally, survey research was dominant, with the exception of randomized clinical trials that were mostly an experimental design. Conclusion: The findings suggest that a robust research design in CAM research is needed to accumulate strong scientific evidence and to adopt nursing interventions from CAM modalities.

In this thesis, We studied on hand-written character recognition, that characters entered into a digital input device and remove noise and separating character elements using preprocessing. And processed character images has done thinning and 3-level wavelet transform for making normalized image and reducing image data. The structural method among the numerical Hangul recognition methods are suitable for recognition of printed or hand-written characters because it is usefull method deal with distortion. so that method are applied to separating elements and analysing texture. The results show that recognition by analysing texture is easily distinguished with respect to consonants. But hand-written characters are tend to decreasing successful recognition rate for the difficulty of extraction process of the starting point, of interconnection of each elements, of mis-recognition from vanishing at the thinning process, and complexity of character combinations. Some characters associated with the separation process is more complicated and sometime impossible to separating elements. However, analysis texture of the proposed character recognition with the exception of the complex handwritten is aware of the character.

In any developing nation major investment goes for infrastructure and it is not exception in India. Good numbers of buildings, bridges, shopping malls, car parks etc. are coming up with steel for sustainable development. Thus protecting the structures from corrosion are the challenges faced by professionals for all types of steel structures. About 3% of GDP is accounted for loss due to corrosion. To combat this up to date corrosion map is called for as the country has wide variation of climatic zones with vastcoastline. Logically organic paint system can be prescribed based on the corrosion rate on bare steel with respect to environment. Present paper will emphasis on the study conducted on two types of structural steel coated with organic paint located in twomarine environment having been exposed for three years, Test coupons made from steels both bare and coated are deployed at two field stations having marine (Digha) and industrial marine (Channai) environments. Various tests like AC impedance DC corrosion, polarisation, salt spray test, $SO_2$ chamber and Raman spectroscopy were carried out both in laboratory on fresh as well as coupons collected from exposure sites. Rust formed on the bare and scribed coated coupons are investigated. It is found that normal marine environment at Digha exhibits higher corrosion rate than polluted marine environment in Channai. Rust analysis indicates formation of ${\propto}$-FeoOH protects or reduces corrosion rate at Channai and formation of non-protective ${\gamma}$-FeoOH increases corrosion rate at Digha. The slower corrosion rate in Channai than at Digha is attributed due to availability of $SO_2$, in the environment, which converts non‐protective rust ${\gamma}$-FeoOH to protective rust ${\propto}$-FeoOH. While comparing the damage on the coated panels it is found that low alloy structural steel provides less damage than plain carbon steel. From the experimentations a suitable paint system specification is drawn for identical environments for low medium and high durability.

Purple rice (Oryza sativa L. var. indica) cv. Kum Doisaket is cultivated in northern Thailand. This study evaluated the mutagenic and antimutagenic properties of hydrophilic and lipophilic components of purple rice using the Ames test. The seed and hull of purple rice were extracted with hexane, methanol, ethanol, and water. The methanol extracts had the highest amounts of phenolic acids and flavonoids, while the hexane extracts contained large amount of tocols and ${\gamma}$-oryzanol. None of the extracts were mutagenic in Salmonella typhimurium strains TA98 and TA100. The hexane extract of rice hull and the methanol extract of rice seed were strongly effective against aflatoxin B1- and 2-amino-3, 4 dimethylimidazo (4, 5-f) quinoline-induced mutagenesis, while aqueous extracts showed weakly antimutagenic properties. All extracts with the exception of aqueous extracts enhanced the number of revertant colonies from benzo (a) pyrene induced-mutagenesis. None of the extracts inhibited mutagenesis induced by the direct mutagens 2-(2-furyl)-3-(5-nitro-2-furyl)-acrylamide and sodium azide. The hull extracts showed more potent antimutagenicity than the seed extracts. Based on a chemical analysis, ${\gamma}$-oryzanol and ${\gamma}$-tocotrienol in the hull and cyanidin-3-glucoside and peonidin-3-glucoside in the seed are candidate antimutagens in purple rice. The antimutagenic mechanisms of purple rice might be related to either modulation of mutagen metabolizing enzymes or direct attack on electrophiles. These findings supported the use of Thai purple rice as a cancer chemopreventive agent.

This study examines the welfare dynamics in Korea under the scheme of National Basic Livelihood Protection Program(NBLP). Data are drawn from Korean Welfare Panel study 2005~2007. Main findings are summarized as follows. First, the exit probabilities show a declining tendency with time on welfare increases. If the exit probabilities indeed decline over time, the earlier years on welfare deserve more interest in the policy perspective. Moreover, the vast majority of recipients are long-termers. Further efforts are needed to increase self-sufficiency through providing genuine opportunity and necessary support for recipients. Second, out-of-poverty exit and out-of-system exit are quite different in their properties. The results from the multivariate analysis confirm that the dropouts through out-of-system exit are virtually the same with those who remain on welfare. These results imply that the government should not resort to the negative policy proposals such as time limit and strengthening sanctions. Third, several explanatory variables have anticipated effect on welfare exit probabilities. Age, education, health, marital status, the presence of children, employment status have a certain level of impact on exit, with the only exception of gender. Since the identification of the determinants can facilitate sensible targeting on the potential leavers, these results have some implications on policy proposals.

Alkali treatment following acidic hydrolysis (ATAH) of defatted soybean is currently used to reduce the level of 3-chloropropane-1,2-diol (3-MCPD), a known carcinogen, in commercial Korean soy sauce. 3-MCPD concentrations in commercial soy sauces made by ATAH were compared with those made only by acidic hydrolysis, and products that combine soy sauce made by acid hydrolysis (followed by alkalinization) and enzymatic methods. The four soy sauces made by ATAH had lower 3-MCPD concentrations (below 0.078 ppm) than 4 commercial products (0.147∼0.481 ppm) made only by acidic hydrolysis. On the other hand, 3-MCPD concentrations in 4 commercial products made by combining soy sauces made enzymatically with that made from acid (with alkali treatment)-hydrolyzed soybean protein in varying ratios were in a range of 0.016∼0.053 ppm. The 3-MCPD concentrations in commercial Korean soy sauces, with the exception of 2 of the soy sauces made only by acidic hydrolysis, were lower than allowable limit of 0.3 ppm in Korea. These results demonstrated that currently produced commercial soy sauces on the Korean market hate toxicologically save 3-MCPD concentrations. It is also provides evidence that ATAH is an effective process for reducing 3-MCPD concentrations in commercial soy sauce.

The purpose of this study is to propose an effective leadership in the hospital management by analyzing the relationship of the effect of the specialty hospital CEO's leadership on the employees' organizational effectiveness as well as the customer orientation, and the mediation effects of the organizational effectiveness on the relation between hospital CEO's leadership and the customer orientation. The questionnaires of the survey targeting the 99 specialty hospitals were collected that 786 copies of them were utilized in analysis. The major outcomes of the research can be summarized as follows. Firstly, transformational leadership of specialty hospital CEO generally has the greater impact on the employees' job satisfaction, organizational commitment and turnover intention than his transactional leadership. Secondly, the most important sub-variable of specialty hospital CEO leadership affecting the organizational effectiveness of the employees are charisma of transformational leadership and contingent reward of transactional leadership. Thirdly, the sub-variable of specialty hospital CEO leadership which has the greatest impact on customer orientation of employees is the active management-by-exception of transactional leadership. Fourthly, the sub-variables in the organizational effectiveness such as job satisfaction, organizational commitment and the turnover intention of hospital employees play mostly the partial mediation role between the customer orientation of employees and the leadership of a specialty hospital CEO. This means that the more the organizational effectiveness of specialty hospital employees improves, the more the customer orientation does. Thus, specialty hospital CEOs need to pay attention to the sub-variables in organizational effectiveness so as to improve the customer orientation of the employees. To explore further the nature of the effect of hospital leadership in the future, apart form the variables of the organization effectiveness used in this study to improve the customer orientation of employees through the leadership of the specialty hospital CEO, the research to identify other factors which have greater influence and explanatory power will be needed.

Organizations pursue a CRM strategy for the purpose of increasing business performance and value. However, firms face a multitude of organizational challenges associated with this endeavor. To reduce their risk of failure, it is suggested that firms undertake a deep analysis of organizational readiness prior to committing to a CRM initiative. Insurance sector is no exception to this fact. There is an increased need to concentrate on the various challenges thrown open by the public insurance firms in implementing CRM. Many insurance firms have invested into customer driven CRM but research indicates varying outcomes (Schmith 2004). While it is clear that there are significant issues involved in the CRM implementation and success and environment faced by the public sector. It is clear that business should have an easier time in applying CRM systems is the strategic value for public sector. With customers demanding more service and accessibility from administrators, public sector CRM software technologies have to offer best solutions for achieving process and cost objectives (Souder 2001). With results which go far beyond improved service delivery and include sustained cost reductions, increased customer knowledge and better employee morale, CRM software implementation and post product environments offer great upside value. Although there are material differences in public sector use of CRM strategy, they share at least one glaring similarity - they have much to gain from proven CRM software technology. As business methods cross over in the public sector, many government bodies are investigating how they can adopt and adapt various CRM models (Bleyer 2003). There is a need to understand the similarities and differences in public sector CRM to foster shared knowledge, business processes and planning functions to integrate disparate technologies and software platforms and then, of course, the organizational culture to support knowledge sharing (Peters 1997). For the public sector, there are clearly identified CRM processes which have resulted in increased profits and improved efficiency. These have focused on sales, marketing and customer service activities, which often operate along fundamentally different lines in various public sector insurance companies. Thus the present research paper makes an attempt to explore how public sector CRM methods can be adopted and subsequently adapted.

Objective: The present study suggested practical measures for successful patent registration based on a review of success and failure cases of patent application filed based on inventions obtained from physical ergonomics research. Background: The protection of intellectual property (IP) contributes to economic growth and competitiveness and facilitates innovation and creativity. IP rights are pursued on research findings for effective technology transfer and commercialization; however, a patent application can be rejected if patentability requirements such as patent eligible subject matter, utility for industrial application, novelty, or non-obviousness are not satisfied. Method: Three successful and three failed cases of patent applications based on physical ergonomics research were reviewed, critical reasons for their successes and failures were examined, and measures were proposed to avoid failures in patent registration. Results: The following measures were identified based on the patent application case review. First, abstract ideas including logical procedures and/or mathematical formulas need to include use of tangible apparatus and methods in idea realization. Second, the provision of grace period inventor disclosure exception needs to be properly followed in case an invention is disclosed before filing of patent application. Lastly, a comprehensive analysis of prior art published or publicly known anywhere in the world and a claim preparation of distinguished, non-trivial features compared to prior art solutions are needed to avoid possible violation of novelty and non-obviousness. Application: The proposed measures can help to prepare a patent application with patent eligibility.
