Ten rice varieties were planted at two locations (lowland and highland), during the wet and dry seasons of different years. In vivo digestibility and voluntary intake of the straw, were determined in groups of fat-tail sheep, supplemented with $18g{\cdot}kg^{-0.75}$ concentrate DM, containing ~20% crude protein. Voluntary intake of digestible straw organic matter (DOMI) consistently varied from 15.2 to $20.9g{\cdot}kg^{-0.75}$ between straw varieties, averaged over locations, years and seasons, despite considerable variation between individual batches. This variation in the nutritive value of the straw was independent of straw and grain yield, so it would seem that there is scope for selection of rice varieties with straw of higher nutritive value. The variation in DOMI of straw among location of growth, year and season, was of a magnitude similar to the improvement brought about by urea-ammoniation. The in sacco degradation characteristics and digestibility of rice straw residues were superior to those of the offered straw. This can be attributed to a preference for rice straw leaves relative to stems. Averaged over location of growth, year and season, characteristics of in sacco degradation, i.e. the rate of fermentative degradation and the truly undegradable fraction, emerged as accurate predictors of the nutritive value of rice straw.

Today, the number of elderly drivers who use navigation is increasing with the growing number of elderly drivers. The purpose of this study is to provide guidelines on the interface of car navigation for elderly users. To extract significant factors which were distinguished between young and elderly users, both young and elderly users executed the driving test by installing two car navigation alternatives. The analysis was conducted through t-test. The results show that significantly different factors were the number and the meaning of the menu items in the initial screen, the location and the meaning of the menu icons in the map screen, the ease of search of the menu and the text size in the menu screen. Improvements for the factors of the initial screen and map screen were made with reference to ergonomic guidelines, and suggested through experiments comparing design alternatives for the menu screen. Design alternatives were made through a combination of investigative variables, and the analysis was conducted through ANOVA. The results show that Alternative 7 (the location of the tab was placed at the bottom, menu representation was done with the text font size of 18pt and the location of menu navigation icons was shown at the upper left) was preferred in terms of user's preference and the execution time. So if the suggested menu for elderly users are added to the existing design, both users will satisfy their desires. The guidelines suggested in this study will help the designer of car navigation take elderly users into consideration.

The purpose of this study is to find out that it can be provided as a basic data to increase the satisfaction with users in the placement and creation of the Green Buffer Zone. In this study, the research was started on the Green Buffer Zone in Gwanggyo new town, which was rebuilt as the zone to use according to the change of legal installation standard of the zone. The subject of this study is the Green Buffer Zone in Gwanggyo new town, which is expected to be completed in step 4 of 2016. As a result of analysing the location and use characteristics of the Green Buffer Zone, the following conclusions were made. First of all, it is categorized into two categories by Buffering / disaster prevention type and land to use adjustment type. Second, the buffer space of commercial space and housing is satisfying, but in commercial space, there is a need for a cushioning function and housing spaces require improvements in the functioning of the landscape. Third, the function of the Green Buffer Zone resets to cushioning function, disaster prevention function, landscape function, utilization function. and The installation criteria are proposed to environmental pollution, noise abatement, and planting trees, etc. Lastly, the future utilization plan considering the location and use characteristics of the Green Buffer Zone is as follows. In the planning stage, preference is given to the characteristics of use of arranging green facility. It is necessary to manage the planned facilities as much as possible by changing them if necessary. Construction stage, it restrictively reflects landscaping facilities within the Green Buffer Zone function. After stage, This study will prioritize the target areas and select necessary areas and need to make efforts to prevent indiscriminate greenery encroachment.

In this study, we classified word problems related to real life presented in elementary mathematics textbooks into five types of context problems(location, story, project, scrap, theme) suggested by Freudenthal(1991), and applied context problems to mathematics class to analyze the influence on students' mathematical belief and attitude. Also, we examined the types of context problems preferred according to academic performance and the reasons of preference within a group experiencing context problems. The results of the study are as follows. First, almost lessons in the mathematics textbook presents word problems related to real life, but the presenting method is inclined to a story type. Also, the problems with a story type are presented fragmentarily. Therefore, although these word problems are familiar to the students, they don't include contextual meanings and cannot induce enough mathematical motives and interests. Second, a lesson using context problems give a positive influence on their mathematics belief and attitude. It is also expected to give a positive influence on students' mathematics learning in the long run. Third, the preferred types of context problems and the reasons of preference are different according to the level of academic performance within the experimental group.

This study has been designed to explore the preferences of interior space for those living in apartment housing. It also examines the relationships between preferences of interior space, such as storage space, organization type of LDK(the living room, the dining room, and kitchen), space facing south, an interior garden, the concept of each room and the characteristics of the consumers, such as age, educational background employment status of homemakers, occupation of the primary income provider, family-life cycle, total household income, the size of floor space, and homeownership. In conclusion, this study suggests that at the time of designing apartment housing units, serious consideration should be given to the built-in closets or storage space in the anbang and to the location of a child's room facing to the south of the dwelling, especially for the families with a child attending primary school or younger and higher education level of homemaker. This study also recommends that the organization of the living room, the dining room, and the kitchen should be varied according to the housing size and the age of homemaker.

The number of household living alone including young single adults has gradually increased. The purpose of this study is to examine the demand on housing options, additional space, shared space, community facilities, housing service for young adults living alone including college students. A total of 180 questionnaire were collected and analyzed. For housing location, commuting distance is the most important feature and amenities are the second important feature. For additional space, there is a significant difference between male and female single residents. Female residents want to install dress room most while male adults want to have a study room. For the shared house option, single adults concerns housing fee and living cost most. However, female adults concern safety and security issues much more than male ones do. The degree of preference to community facilities varies between male and female single residents. The findings suggest more differentiated approaches are needed for alternative housing options for male and female residents.

This dissertation is about a study on the space planning of take-out coffee shops grouped by type. The classification is based primarily on stand-alone shop, which runs independently, and shop in shop, located inside of another shop with different industry. And its subdivision is characterize by 3 types: Combination type has not only space to enjoy coffee as we can usually see in conventional coffee shops, but also a counter where take-out coffee is served. Separation type has space for drinking coffee and an external booth for easy buy. Booth type is a booth itself or driving (cruising) booth. In conclusion, some take-out coffee shop are exampled and space analysis is made with analytic tools, such as people of preference, location evaluation, functional space division, dimension per person, and planning of traffic line.

Data mining technology is frequently used in identifying the intention of users over a variety of information contexts. Since relevant terms are mainly hidden in text data, it is necessary to extract them. Quantification is required in order to interpret user preference in association with other structured data. This paper proposes rating and comments mining to identify user priority and obtain improved ratings. Structured data (location and rating) and unstructured data (comments) are collected and priority is derived by analyzing statistics and employing TF-IDF. In addition, the improved ratings are generated by applying priority categories based on materialized ratings through Sentiment-Oriented Point-wise Mutual Information (SO-PMI)-based emotion analysis. In this paper, an experiment was carried out by collecting ratings and comments on "place" and by applying them. We confirmed that the proposed mining method is 1.2 times better than the conventional methods that do not reflect priorities and that the performance is improved to almost 2 times when the number to be predicted is small.
