This study investigates the prosodic characteristics of Korean through the analysis of a large database. One female and one male speakers each read 650 sentences and they were segmentally and prosodically labeled. Statistical analyses were done on these utterances regarding the tonal pattern and the size of prosodic units, correlation between the size of higher level prosodic units and the number of lower level prosodic units. and the slope and F0 of the falling and rising contours of an accentual phrase. The results showed that the duration and the number of words and syllables of a prosodic unit were significantly different not only between speakers but also between its positions within a higher level prosodic nit. The munber of a prosodic unit showed a high correlation with the duration and the number of syllables of its higher level units. The slope of the falling contour within an accentual phrase was inversely Proportional to the number of its syllables. The slope was different depending on the first tone type of an accentual phrase, which could be explained with the F0 rising and the different amount of rising between tones when an accentual phrase starts with an H tone. The slope of the falling contour across an accentual phrase boundary showed a constant and larger value compared to one within an accentual phrase. The rising contours in the beginning and end of an accentual Phrase were similar in their slopes but they differ in the amount of F0 change : the former showed a larger amount of change. The slope of the rising contour which forms an accentual Phrase on its own was inversely Proportional to the number of its syllables.

This study is to suggest a system to increase workers' job satisfaction by analyzing the impact of conflicts in their families and work places to the satisfaction of work and the effects of personality types affecting job satisfaction. For this study, a questionnaire targeting 450 workers was conducted. As a result of this study, firstly, it was revealed that both conflicts of the family-work place and the work place-family have statistically negative interrelationships and impacts with/on job satisfaction. In terms of sub-fact categories, it is revealed that work itself has more impacts than personal persuasion based on people's value. Secondly, the results of this study concerning the conflicts in a family and the workplace shows the same result with the previous studies. They are formed by mutual interactions of cause and effect. Thirdly, it turned out that differences in Enneagram Personality Types have statistically significant impacts on job satisfaction. The result also shows that thinking-centered personalities and behavior-centered personalities have more impacts on job satisfaction than emotion-centered personalities. Study result indicates that more wide use of a psychology consultation program for workers and their families, EPA(Employee Assistant Program). It also shows that introductions of personality trainning programs and personality coaching programs are required.

To analyze the effectiveness of horticultural therapy reported in research papers, a meta-analysis was carried out with 108 of 377 Korean and overseas research papers on horticultural therapy from 1985 to February 2009 (196 Korean dissertations, 113 Korean journal articles, 5 overseas dissertations, and 63 overseas journal articles). The results revealed a large effect size of 0.71. The effectiveness according to the type, age and number of participants were also analyzed. The therapy was most effective in children, and it was more beneficial for children with special needs and elderly people affected by dementia than for the typical population. The greatest effect was found with group sizes of five people or less, and when carried out by researchers from departments related to horticultural therapy than by researchers from unrelated fields of study. The most effective horticultural therapy programs involved floral decorations; and participants who took part in 21 to 30 sessions or at least 31 sessions benefited the most. Among the main effects of short-term horticultural therapy are cognitive, social, physical and emotional; the greatest effect was observed in the physical domain.

An analysis is presented of key phenomena and scenario which imply some general trends for beyond design-basis-accident in Kori-1 PWR dry containment. The study covers a wide range of severe accident sequences initiated by small break LOCA. The MARCH computer code, with KAERI modifications was used in this analysis. The major emphasis of the paper are two folds, 1) the phenomenologic understanding of severe accident and 2) a study of H2 combustion and debris/ water interactions in a specific small break LOCA for Kori-1 plant. The sensitivity studies for the specific plant data and thermal interaction modelings used in the SASA were performed. The results show that if hydrogen burning does occur at low concentration, the resulting peak pressure does not exceed the design value, while the lower concentration assumption results in repeated burning due to the continuing H$_2$ generation. For debris/water interaction, the particle size has no effect on the magnitude of peak pressure for the amount of water assumed to be in the reactor cavity. But, the occurrence of peak pressure is considerably delayed in case of using the dryout correlation. The peak containment pressure predicted from the hydrogen combustion and steam pressure spite during full core meltdown scenario does not present a severe threat to the containment integrity.

The purpose of this study is to derive a curriculum environment for operating various student-centered teaching and learning methods, and the following results were derived: First, most of the lectures, discussions and consultations, data search, report preparation, presentation, work exhibition, and others were commonly derived, regardless of the types of long-term and short-term project classes for each subject. In particular, the necessity of operating various classes at the same time was suggested, indicating the need for an integrated teaching and learning operation environment in the unit subject class. Second, considering that practical classes are linked concurrently to lectures and discussion classes to conduct one subject class, it is necessary to switch to a specialized curriculum system that allows various classes such as lectures to be carried out at the same time. Third, as a result of grasping the appropriateness of the space size of the subject class for realizing different class types in the future, it can be seen that the space size of the practice room, including the space for practice and the area for exhibition, should be expanded. Based on the research results, the spatial environment for the operation of future teaching and learning classes is based on the public curriculum classroom system, and whether professional curriculum classes, such as lecture rooms and discussion and presentation rooms, are secured according to the number of students.

The purpose of this study is to analyze the correlation and the causal relation between the service quality, customer satisfaction and revisit intent of an urban railway. A structural equation model(SEM) was developed and analyzed using SPSS 21.0 and AMOS 21.0. The results showed that it satisfies the fitness of the model mostly: the reliability, convenience, safety of the service quality have a significant positive impact on the customer satisfaction (p<.05) and the tangibles(-.187) and responsiveness(-.103) have no impact on the customer satisfaction (p>.05.). The customer satisfaction has a significant positive impact on revisit intention (p<.001). The factors affecting the service quality and customers' satisfaction were found to be ranked as the order of reliability, convenience, safety, responsiveness, tangibility based on the high priority. The findings of this study will contribute to provide a practical tool to establish a mid-long term management plan and management strategies for boosting the customer satisfaction and creating revenue through the customized service of urban railway operating industry suffering chronic deficit.

The national highway traffic counts system consists of short duration counts and continuous counts. Unlike continuous counts, short duration counts are performed by collection of a few days period and thus, the magnitude of deviation of collected data from AADT varies depending upon when data collection takes place. Therefore, this study was done to find out the best months and days of data collection of each highway classification in order to enhance the accuracy of AADT estimation. Continuous counts, another type of the national traffic counts system, are performed by collection of 365-day period using a permanent traffic counter. Therefore, it is necessary to keep the number of days for which the counter malfunctions to a minimum in order to enhance the accuracy of data. However, from time to time the permanent traffic counter malfunctions due to various causes and thus, cannot collect data. Therefore, this study was done to find out whether the age of counter, the ratio of heavy vehicle volume to total traffic volume, etc. could be the direct causes of counter's malfunction based on the number of maintenance for a certain time period.

The dorsal lingual papillae of Sorex caecutiens were studied morphologically using scanning electron microscopy. Three types of lingual papillae were found: filiform papillae, fungiform papillae and circumvallate papillae. Filiform papillae were observed in most part of the tongue except on the lateral surface. There were basically three types of filiform papillae distinguished mainly by their morphological shape and structure. Numerous fungiform papillae were spread throughout the whole tongue, especially concentrated in lateral sides. The size varied according to the position of fungiform papillae, becoming larger as it reached to the rear. Strict pair-wise distribution was not observable, but fungiform papillae were mostly located in orderly manner. There were two large circumvallate papillae at the posterior region of the tongue. There were two thick pads around the center part where several bodies were gathered together. Overall research provided similar results with other close species such as common shrew (S. araneus). The circumvallate papillae of S. caecutiens were different from other Sorex species. They were circular, as in bats and other Sorex species, and had two distinguishable pads while others had only one.

The research of the variability gains more gravity in component-based software development, because it helps to extend the reusability of the component. A domain-specific component supports the more variability, the wider scope that the component can be applied to. However, the more variability included in a component, It makes the size of a component bigger, and the cost to construct the component is rises. As a result, this disturbs making an optimized system. In this paper, we classify the variability into 3 types, according to their features. And we propose some implementation techniques for each type based COM. Moreover, we also propose a process to analysis and design the variability with their artifacts, which includes some tasks from variability extraction to implementation of it. This proposed process can be applied as a part of the component developing process.
