Predicting the right prosodic elements is a key factor in improving the quality of synthesized speech. Prosodic elements include break, pitch, duration and loudness. Pitch, which is realized by Fundamental Frequency (F0), is the most important element relating to the quality of the synthesized speech. However, the previous method for predicting the F0 appears to reveal some problems. If voiced and unvoiced sounds are not correctly classified, it results in wrong prediction of pitch, wrong unit of triphone in synthesizing the voiced and unvoiced sounds, and the sound of click or vibration. This kind of feature is usual in the case of the transformation from the voiced sound to the unvoiced sound or from the unvoiced sound to the voiced sound. Such problem is not resolved by the method of grammar, and it much influences the synthesized sound. Therefore, to steadily acquire the correct value of pitch, in this paper we propose a new model for predicting and classifying the voiced and unvoiced sounds using the CART tool.

This paper presents a new reflectarray antenna capable with 1-bit switchable capability for W-band beamforming network. The proposed antenna has been optimized using two unit-cells with sizes of 1.0 mm and 1.3 mm to form a total number of 193 radiating elements on a square aperture surface of length 30 mm. These radiating elements are spaced 0.5 wavelengths apart and fed by a 15 dBi pyramidal horn antenna as the feed antenna placed 53 mm away from the aperture center. The proposed reflectarray achieves a realized peak gain of 22.52 dBi, a half-power beamwidth of 5.1° in both E- and H-planes at the test frequency of 80 GHz and operates over a wide bandwidth from 74 GHz to 90 GHz.

The incorporation of ³H-proline by epithelial and connective tissue elements of rat palatal mucosae was studied in order to investigate the relative levels of protein synthesis by the epithelium and underlying connective tissue cells. Following a sixty minutes incorporation of the radioactive tracer in vitro, it was found that the suprabasal cells had most grains per unit area. Furthermore, the grains were more concentrated over the cytoplasm than the nucleus. This was in contrast with the labeling of basal cells which had twice as many grains over the nucleoplasm than that over the cytoplasm. In intermediate cells; i.e., the spinous layer, the number of silver grains per unit area was decreased from that of the suprabasal cells. In areas where desmosomes were more prominent, many grains were in touch with such desmosomes. However, the labeling appeared to be reduced as soon as the cells became flattened. Moreover, the epidermal keratohyalin granules were relatively free of grains. Except for certain intercellular surfaces the keratinized cells were generally free of grains. On the connective tissue side, silver grains were primarily localized over the fibroblasts with occasional grains being found over palatal muscle cells, neural elements and so on. Most grains over collagenous fibers were found in relation to mature collagen fibrils. Thus, protein synthesis in isolated mucosae of the rat palate appeared to take place both in epithelial and connective elements. There were no apparent tissue alterations caused by the in vitro incorporation procedure utilized under conditions of this study.

The results of the research were as follows: The entire space of the village was based on natural formation in its initial formation stage. The traditional location conditions and environment were equipped with the possibility and conditions for the development of the village. Spatial boundaries were mostly divided by natural topography. The quantify of lots diminished in spatial structural factors, while the division of roads by hierarchy in terms of size became explicit. Alleys, as the minimum hierarchial nit, were degraded. The residence unit was focused on economic efficiency. Communal use facilities showed an external relations trend as central facilities. The land, unit residence and communal facilities approached the high hierarchial roads. The communal facilities showed relatively higher independence compared to the residence units. The spatial structural changes followed traditional life style in the initial stage of village formation; however, social elements mainly impacted on the changes. Since reform opening, economic elements were major causes of changes, while construction conditions, life style, and awareness of structures impacted upon the changes. Thus, the economic element is the major change element in the Korean Villages, even though other elements will also become diverse.

This study investigated the National Competency Standards (NCS) of fashion planning to compare the fashion planning curriculum of domestic universities and colleges with NCS as well as suggest ways to activate the application of NCS to fashion planning education. Qualitative research was employed based on references from the old and new homepages of NCS as well as fashion planning related subjects of domestic universities and colleges. The results are as follow. First, fashion planning NCS was composed of 10 competency units. Competency units were composed of competency unit elements and performance criteria. The levels of the competency units and the competency unit elements were suggested based on 8 stages. There were significant differences in the content of competency units and the level of competency units between the old version and the revised version of fashion planning NCS. Second, considerable fashion planning related subjects seemed at a higher level than the function level of recent college graduates. There were also omitted subjects which were required for recent college graduates. Third, the requirements for the reorganization of curriculums and education systems as well as the cooperation among industry, colleges, universities, and development part of NCS were suggested for the activation of NCS based education and the validation of NCS.

The Korean government required the mandatory ratio of public housing including the housing unit for elderly in February 2012 and the number of them is expected to increase accordingly. To prepare for an aged society, these enabling ubiquitous technology will be able to support efficient health care services, which was mentioned in various studies. Therefore, the aim of this study is to draw the design elements for an apartment for providing health care services according to the degree of independence of elderly people and to grasp the current situation and work out tactics by the evaluation of four actual cases. In housing unit in the elderly housing project, design elements supporting amenity improvement was rated to the highest importance, however, in reality, was reflected at lower rate while the risk management plan for public space was applied at the highest rate. Design elements required by new technology such as health monitoring and community management with outside world are still not reflected, however, in order to realize the concept of 'aging in place', health care services in various aspects should be considered in housing planning.

The purpose of this study was to develop Graphic Organizer as Advance Organizer. The 'Menu Planning and Food Selection' unit of second grade middle school Technology & Home Economics(revised curriculum of 2007) was selected as the study subject. The course of abstracting an essential education element got done $3^{rd}$ times. It abstracted the first essential education elements to analyze the presented sentence or a concept with the educational contents factor which is on the achievement standard of the area of dietary life from 5grade to 10grade in curriculum revised in 2007. The first 4 essential education elements selected were superiority and cultural value of Korean traditional meal, preparing a balanced diet for the family, food purchasing, and food selection based on the various information'. It abstracted second essential education elements that it concretized the first content factor on a unit of this study and solved overlapping when it was happened at the first contents factor and made connecting with between grade. The $3^{rd}$ essential education elements abstracted to classify the contents which abstracted essential education elements in second. And, it developed Graphic Organizer on a unit of 'Menu Planning and Food Selection' in eight-grade Technology & Home Economics based on the abstracted essential education elements. Graphic Organizer was developed in according to order of the way for making on a Concept Map of Heo In Sook(2000). Developed Graphic Organizer is all of 10 which are 'nutrition value on food of the season', 'harmony and combination of food', 'natural dressing and a garnish', 'the recipe', 'fermented food', 'a traditional instrument and a vessel', 'actor of food harm', 'present food', 'food quality certification' and 'selecting food with food information'.

The purpose of this study is to understand various styles of Korean house living, up to the present, to identify apartment living as the main house living, and plan and propose the interior unit spaces for apartment house based on the analysis on living space. A survey study was conducted to deduce the traditional major life style and its changes along with favorable housing spaces. In conclusion, this study proposed the unit space planning requirements that satisfies the conceptual and interior elements for habitant's characteristics and preference according to major life style as follow; 1) As the Ahn-bang(master bed room) has been changed from traditional space concept, it is mainly used as private space for husband and wife, and its utilized period is mostly at night time, the back-arrangement of the Ahn-bang should be considered. 2) As the living room is central space in the apartment housing and has complex functions which is utilized as space for family gathering and guest reception similar to the Ahn-bang of the traditional house, it should secure more space and it is desirable to arrange the space as open type by combining the pathway area. 3) As for the kitchen/dining room, the kitchen should be isolated from external attraction and the space for storing and preparing traditional foods should also considered, and the dining room should be arranged as open type. This study also suggests that since the apartment housing must be an integrated environment for habitants which satisfy behavioral, physical and mental elements simultaneously, the unit housing space should be constantly analyzed in various ways to produce a housing space which meet both their changing major life style and the temporal environment.
