To get more natural synthetic speech generated by a Korean TTS (Text-To-Speech) system, we have to know all the possible prosodic rules in Korean spoken language. We should find out these rules from linguistic, phonetic information or from real speech. In general, all of these rules should be integrated into a prosody-generation algorithm in a TTS system. But this algorithm cannot cover up all the possible prosodic rules in a language and it is not perfect, so the naturalness of synthesized speech cannot be as good as we expect. ANNs (Artificial Neural Networks) can be trained to learn the prosodic rules in Korean spoken language. To train and test ANNs, we need to prepare the prosodic patterns of all the phonemic segments in a prosodic corpus. A prosodic corpus will include meaningful sentences to represent all the possible prosodic rules. Sentences in the corpus were made by picking up a series of words from the list of PB (phonetically Balanced) isolated words. These sentences in the corpus were read by speakers, recorded, and collected as a speech database. By analyzing recorded real speech, we can extract prosodic pattern about each phoneme, and assign them as target and test patterns for ANNs. ANNs can learn the prosody from natural speech and generate prosodic patterns of the central phonemic segment in phoneme strings as output response of ANNs when phoneme strings of a sentence are given to ANNs as input stimuli.

Studies about nutritional status, dietary behaviors and food preferrence as well as health status were performed to 110 homo-living elderly in rural area, Asan. The results obtained by questionnaires and interviews for 24-hr dietary recall were as follows. They were 68.6 years of average age. The weights were 53.8kg and 51.4kg of male and female, respectively and BMI 22.0 and 23.5. Their prevalence of obesity and high blood pressure were 65.5% and 60.5%, respectively, which seemed to be less than ones in large cities. More than 50% of the elderly thought their health as good or so-so. Physical health conditions by check list were indicated as 2.26 points, which meant the listed physical symptoms observed seldom(3pts) to sometimes(2pts). Evaluations on food frequency and seasoning tendency resulted in superior quality of female elderly's meals to that of male ones. Average daily intake of energy, protein, vitamin A, riboflavin and ascorbic acid of the elderly in rural area were lower than Korean RDA for the aged $60{\sim}69$ and riboflavin was found to be the least sufficient nutrient. Their monthly expenditure, meal-accompany and skipped meals were significantly related to daily nutrient intake.

Purpose : This study was performed to develop a scale of outdoor school safety behavior in Korean elementary students. Methods : A list of 40 items were selected by priori experiences of school health teachers and a literature review. For evaluation of the appropriateness of the 32 items, questionnaires were reviewed by an expert group which was consisted of 10 professionals. Validity of the 31 items was screened in this process with 4 point Likert scale. Using the preliminary tool. data were collected from 684 subjects for item analysis and factor analysis. A total of 26 items were remained, and items with the lower than 0.2 item-total correlation coefficient were removed. Factor analysis was done with these 26 items, and 26 items with factor loadings higher or equal to 0.4 were remained. Relsult : 1. Cronbach's alpha for the 26 items was 0.70 2. Five factors were identified with eigen value 1.0 These contributed $51.617\%$ of the variance in the total score. 3. Each factor was labled 'vonobserbance of safety rule', 'good habit for safety', 'careless action', 'lack of safety knowledge', 'injurious action to friend' It is suggested that this scale could be used to measure outdoor school safety behaviors among elementary students in Korea.

The major purpose of this thesis is to construct the evaluating framework of a science textbook with a high confidence and universal validity, referring to a preceeding study and materials involved in research work, and in consideration of the educational conditions of the secondary school. The framework developed in this study are composed of 7 categories: content, organization, representation, laboratory, illustrations, external form or editing system, and supplementary materials. Each category consists of detailed items. Eech item in the check-list is to be given between one and five points, and the total number of possible points in this evaluating framework is 290. As a result, these evaluating items enable quantitative analyses, afford an opportunity which we can look into many-sidedly the respects we should consider when a science textbook is adopted, and they can be estimated partly or synthetically as occasional demands. This study is exepected to contribute to choose a good science textbook as fundamental data in the future, and to help the lasting study or estimation of the textbook.

Purpose: The purpose of this study is to propose useful suggestions by analyzing difference of financial performance between "Excellent Quality Competitiveness Enterprise(EQCE)" awarding companies and all the manufacturing companies during the period 2003-2014 and by testing the moderating effects of performance year. Methods: This paper perform the longitudinal study during the period 2003-2014. The collected data through list of National Quality Award and financial report of CRETOP were analyzed using independent-sample t-test, paired-sample t-test, one way ANOVA and empirical analysis. Results: The results of this study are as follows; EQCE showed higher growth rate than all the companies until 2008, but profitability, stability, and activity are not significantly different between the both. Therefore EQCE have partial influences on growth rate among several financial performance measures until 2008. Since 2009 there are no differences. The effects of EQCE on financial performance are different by the year. Conclusion: EQCE award system was a meaningful promotion method to enhance good financial performance through encouraging quality management for the manufacturing companies until 2008, But since 2009 it is expected to lose its role as a promoting tool for quality management and performance excellence. Therefore new way of thinking for EQCE, as a national quality award system, is necessary; changing awarding system, award criteria, or etc.

In the case of uploading privacy information of an information owner in the Internet, the information owner may want to deliver the privacy information itself or remove such information from the search list in order to prevent third parties from accessing the privacy information of the information owner. Such a right to be forgotten may collide with the freedom of expression of a third party. The right to be forgotten, which originates from the self-determination right on privacy information based on Article 10 and 17 of the Constitution and the freedom of expression, which is based on Article 21 thereof are all relative basic rights and are both limited by Item 2 under Article 37 of the same law, which is the general limitation provision for the basic rights. Therefore, when the right to be forgotten and the freedom of expression collides, it is not possible to give priority to one of the those unilaterally. It depends on the nature of the case at hand to find a natural balance for the harmonious solution for both parties. The criteria can be the sensitivity to the privacy of the information owner caused by the disclose of the privacy information, the public benefits such information may serve, the social common good that could be expected by the disclosure of the privacy information and the damages suffered in terms of the personal interest caused by the disclosure of the information, in a comprehensive manner.

A number of studies in recent years of have begun to look at the connection between country affinity (an interest in and admiration of a particular country) and a desire to buy the products and services of that country. Country affinity has been shown to be particularly important when consumers lack other sources of information about a good or service. However, except for direct questioning, methods to identify the affinity consumers might have for another country are lacking. This study examines the degree to which attending a movie set in a particular country will be related to an affinity for that country and possibly by extension the goods and services of that country. It is not the goal of this study to suggest that movies create the affinity, but rather that that the affinity will exist for viewers of the films. Two films set in Ireland and featuring Irish actors where shown to audiences composed of Korean students and a small number of Korean adults. As a point of comparison, students in two introductory consumer classes were also asked to complete a similar questionnaire. Four affinity factors were identified from a list of 17 items. Those who attended the historical drama showed a greater affinity for Ireland than those who attended the romantic musical. Affinity for Ireland among Koreans was also meaningful in predicting interest in purchasing Irish products.
