In this study, we suggest a policy for setting the direction of Jeju Music Education with implications from the process of arranging philosophical theories related to music education and analyzing advanced cases. The philosophical theories of music education were examined by Schiller, Steiner, Dewey, Bourdieu, Reimer, and Elliotts. In addition, this study checked the lessons in music education programs in Germany, Venezuela, and Finland, and we make policy suggestions in four contexts to set the direction of music education in the Jeju community based on interviews with 10 experts. Suggestions for improving social awareness of music education, suggestions for music education in the elementary and secondary public school sectors, in the proposals for music education in the lifelong education sector, and the suggestions for institutional policy all included music education professionals recruited from among the culture and art sectors within the Jeju Special Self-Governing Province's Cultural Policy Division. Music advisors were also recruited from the music and sector music councils within the Jeju Special Self-Governing Province Council.

The effects of green manure crops, hairy vetch and sesban, supplemented with HS (humic substance) on biological soil health indicators was studied in a pot containing two kinds of reclaimed soil previously contaminated with petroleum hydrocarbons; a soil remediated by land-farming (DDC) and another soil by low-temperature thermal desorption (YJ). Treatments include no plant (C), plants only (H), and plants+2% HS (PH), which were evaluated in a pot containing respective soil. Biological indicators include microbial community analysis as well as soil enzyme activities of dehydrogenase, 𝛽-glucosidase, N-acetyl-𝛽-D-glucosaminidase (NAG), acid/alkaline phosphatase, arylsulfatase, and urease. Results showed an increase of enzyme activities in pot soils with plants and even greater in soils with plants+HS. The enzyme activities of DDC soil with plants (DDC_P) and with plants+HS (DDC_PH) increased 1.6 and 3.9 times on average, respectively than those in the control. The enzyme activities YJ soil with plants (YJ_P) and with plant+HS (YJ_PH) increased 1.8 and 3.8 times on average, respectively than those in the control. According to microbial community analysis, the relative abundance of nitrogen-fixing bacteria in DDC and YJ soil was increased from 1.5% to 7% and from 0 to 5%, respectively, after planting hairy vetch and sesban. This study showed that mixed planting of green manure crops with a supplement of humic substance is highly effective for the restoration of biological health indicators of reclaimed soils.

Optimum Ship Routing can be defined as “The selection of an optimum track for a transoceanic crossing by the application of long-range predictions of wind, waves and currents to the knowledge of how the routed vessel reacts to these variables”. This paper treats the methodology how to serve optimum ship routing problem by network modeling and reveals the validity of the network model by some numerical experiments.

In this paper a practical limit load estimating procedure is proposed for general pipe-elbow structures subjected to complex loading (in-plane and out-of-plane bending, internal pressure and axial force). The explicit calculating formulae are presented on the basis of theoretical analysis combined with numerical simulation. Von Mises' yield criterion is adopted in both analytical and numerical calculation. The finite element examination shows that the method provides a simple but satisfactory prediction of pipe structures in engineering plastic analysis.

In this paper, we provide a mathematical formulation to describe the random mobility of users in cellular radio systems. With this, we can also study tile cell sojourn time (CST) distribution as well as the channel holding time (CHT) distribution. The study on user mobility enables to improve the resource management in cellular radio systems. We provide a versatile analysis tool that improves the limit of simplified analyses.

The least squares method is usually applied when estimating the parameters in the regression models. However the least square estimator is not very efficient when the distribution of the error is skewed. In this paper, we propose the asymmetric least square estimator for a particular nonlinear time series regression model, and give the simple and practical sufficient conditions for the strong consistency of the estimators.

Consider the several methods of constructing interval for relative ration from two independent binomial samples. The special interests are gives in the cases of low rates and small samples. bias-corrected and accelerated bootstrap method is proposed to overcome are the non-efficiency of current methods based on asymptotic resuts. Simulation studies are presented to demonstrate the performance of the proposed method.

I wish to acknowledge the people who inspired me to believe that a machine can have intelligence. They are the ones who envisioned the future of mankind. I specially appreciate to my advisor Dr. Srivasan raghunathan, who was always supportive and encouraged to finish this research. I also sincerely thank for my parents who are always concerned of my well-being. Without them, what I achived here cannot be possible.

This study is a critical assessment of research productivity through publication among scientists and engineers. Through the analysis of the 223 mail questionnaires collected from professors of mechanical engineering, electrical engineering, chemistry and physics, this study obtains the particular determinants of publication productivity at the science and engineering schools in Korea. The data are analyzed using correlation, ANOVA, multiple regression analysis and path analysis. The result shows that early research productivity and the number of doctoral students are very important to publish good research articles. Also the qualities of professors' Ph.D. institution and the quality of employing university are critical influencing factors to publication productivity.

Bayesian methods are considered for the multiple caputure-recapture data. Reference priors are developed for such model and sampling-based approach through Gibbs sampler is used for inference from posterior distributions. Furthermore approximate Bayes factors are obtained for model selection between trap and nontrap response models. Finally one methodology is implemented for a capture-recapture model in generated data and real data.
