This study was an exploratory research to classify the types of green fashion marketing of the fashion companies in South Korea and analyse the present cases of each type. To analyse the current cases of green fashion marketing strategies, we researched all sorts of newspapers, magazines, publications of fashion companies, and web sites from 2008 to 2009. As a result, we categorized 5 types of green fashion marketing as follows ; eco-friendly fabrics (natural fabrics, recycled fabrics, biodegradable fabrics), re-use or re-form(reuse after cleaning and/or repairing and reformation through transformation and combination of raw materials), green certifications(ISO 14001, GOTS, OES, etc.), eco-friendly management and operation, and green marketing promotions. Based on the results, we proposed the green marketing strategies for fashion companies to progress toward the proper direction of green marketing. First of all, companies should escape from the narrow view point limited to the product itself. Then they have to focus on developing and execution of sustainable merchandising, manufacturing, logistics, and waste strategies.

In this paper we analyse performance of value strategy and moving average method among the non-financial listed companies whose fiscal year ends at December in the Korean Stock Exchange between 1996 and 2005. And we analyse combination investment performance of value investment and moving average method. After the analysis objective enterprises divide with the value stock and the growth stock, in accordance with moving average method we divide ascending stock and descending stock. And we compose 6 portfolios with combination of value stock, growth stock, ascending stock and descending stock. Using the difference of investment performance of these portfolios, when fundamental analysis and technical analysis method all considering we measure investment performance. The major findings of this research are as follows: First, the value strategy of buying value stocks and selling growth stocks were effective in the long-term investment. Second, using the moving average method, technical analysis were effective in the case of the short-term investment. Third, the portfolios combined fundamental analysis and technical analysis were more effective than investment performance of technical analysis.

These days, geographic information system has released in everyday life and industries. However, the shipyard only uses it to manage the layout of the yard. In this study, we apply the Geographic Information System to shipbuilding block logistics simulation to analyse the behavior of bogies and forklifts carrying blocks and materials in the shipyard. The shipyard manages daily block logistics plans at the execution planning stage. However, since it is a daily plan, it is difficult to respond to an unexpected situation immediately, and application to judge a certain value or higher value is insufficient. Therefore, a simulation model was created using the shape and attribute information inherent in the geographic information system to verify and improve the block logistics of the mid-and long-term yards. Through this simulation model, we will analyse loads on the workplace, stockyard, and road, and contribute to overall logistics improvement from the point of view of resource planning. In addition, the results of the simulation are reflected in the planning, to help support various decisions.

The paper describes four practical cases of railway structure concerning a three-dimensional numerical approach to analyse dynamic soil-structure interaction(SSI)of railway tracks on layered soil under transient load in the time domain. The SSI-Model has been implemented in TDAPIII accounting for nonlinear properties of the track and soil. The approach can be also be used to calculate vibration propagation in the soil and its effect on nearby buildings and structure. The Method is applied to analyse the dynamic response of railway tracks due to a moving wheel set. Finally some sample are given in order to reduce the vibration at the point of emission, at the transmission path and the structure itself.

Verbal communication is the most commonly used mean of communication. A spoken word carries a lot of informations about speakers and their emotional states. In this paper we designed a model to recognize emotional states in a speech, a first phase of two phases in developing a toy machine that recognizes emotional states in a speech. We conducted an experiment to extract and analyse the emotional state of a speaker in relation with speech. To analyse the signal output we referred to three characteristics of sound as vector inputs and they are the followings: frequency, intensity, and period of tones. Also we made use of eight basic emotional parameters: surprise, anger, sadness, expectancy, acceptance, joy, hate, and fear which were portrayed by five selected students. In order to facilitate the differentiation of each spectrum features, we used the wavelet transform analysis. We applied ANFIS (Adaptive Neuro Fuzzy Inference System) in designing an emotion recognition model from a speech. In our findings, inference error was about 10%. The result of our experiment reveals that about 85% of the model applied is effective and reliable.

Korea has constructed a high speed Internet service which is widely used for cyber education by Korean. In composition and operating systems, cyber education is different from off-line education. Colleges have to analyse factors related to active education and make the factors have optimal effect for cyber education. In this paper, we meet the needs of the present trends, arrange and classify activation factors of cyber education. In addition, to improve effective operating systems of cyber education, we survey, and analyse participants' satisfaction ratings. The result of the survey is used in our proposal for promoting cyber education.

Among different geometrical representations of a mathematical concept, learners are likely to form their geometrical concept image of the given concept based on a specific one. A learner's image is not always in accord with the definition of a concept. This can induce his or her errors in mathematical problem solving. We need to analyse types of such errors and the cause of the errors. In this study, we analyse learners' geometrical concept images for geometrical concepts and errors related to such images. Furthermore we propose a theoretical framework for error analysis related to a learner's concept image for a general mathematical concept in mathematical problem solving.

The purpose of this study is to analyse the job-satisfaction of police officer. The subjects of this study are selected by convenience sampling of random sampling method. The population is male and female incumbent police officers in Seoul and Gyeonggi province. The 347 cases are used to analyse the job-satisfaction among 400 police officers who answer the question. The Jod-Satisfaction Survey(Choi, 2001) are used for collecting data. In consequence of and 4 sub-factors(job-satisfaction) are found. Cronbach's alpha coefficient revealed $.058{\sim}.804,\;.846{\sim}.871$, respectively. For the statistical analysis, SPSS version 12.0 are utilized. The verification of research hypothesis are conducted by T-test, ANOVA, correlation, and multiple-regression. The significance level of all tests are set at .05. The findings of this study can be summarized as follows: Based on the demographic factors, the differences in life-style among police officers are identified. There is significant differences in gender and ages on individualism and accomplishment, in marital status on individualism and fashion-pursuing, and in income level on fashion-pursuing and accomplishment. There is also significant differences in education, religion, position and service period on accomplishment, individualism and fashion-pursuing.

The purpose of this study is to analyse the risk and uncertainty involved in the capital budgeting which is executed in long periods and requires massive capital expenditure. Under risk and uncertainty conditions, the estimates in the capital budgeting are random variables rather than known constants. Two approaches have emerged in performing economic analysis that explicitly incorporate risk and uncertainty conditions in the analysis. One approach is to develop a descriptive model which describes the economic performance of an individual investment alternative. But no recomendation would be forthcoming from the model. Rather, the decision-maker would be furnished descriptive information concerning each alternative; the final choice among the alternatives would required a separate action. The second approach is to develop a normative model which includes an objective function to be maximized or minimized. The output from the model prescribes the course of action to be taken. Owing to the fact that the normative approach considers the fitness of criteria for decision-making its reasonableness looks better. But it is almost imposible that we correctly and easily derive the individuals' utility function. So within we recognize the limits of the descriptive methods, it is more practicle to analyse the investment alternatives by sensitivity analysis.
