Most large-sized and tall-risen general hospitals of today fairly depend on in-patient wards in designing hospital styles. The core planning for the efficient movements of various people in the words should take into account the sustainable connections between/among the floors, as well as hospital structures and mechanical functions. This study sampled for the study 19 hospital in-patient wards and investigated their flat-core styles. It was found out that hospital structures are changing from symmetrical styles of triangles, quadrangles and rectangles through bending, configuring, transforming to efficient new styles. Symmetrically quadrangled flat-styles are made of multi-cores spread with main an sub-cores. In contrast, symmetrically triangled flat-styles place the open place in the middle in order to prevent from its deepening, and widened the depth line through changing the outdoor top point. Non-symmetrical rectangles minimized the depth value to maintain the recent styles used in the wards, and tended to prefer the transformed styles of quadrangles. The double-corridors easily transshaped from mono corridors reveals the triangled, W-shaped, or Y-shaped figures. The site area ratio of the cores is 11.95% in average. The number of beds which one elevator covers is 66.51 beds in average, and the size of site area which one elevator covers 216.68m. Most cores on the base floor clustered around the average value, with more than 1000 beds shoes 12.83%, does 12.93%, does 14.64%, does 14.58%, which says that the core ratio increases according to hospital beds.

The ultimate goal of environment education plays an important role in forming knowledge, skill, attitude and a point of value along with sustainable development in the regions. Recently, however, environment education is comparatively despised due to college-entrance-exam-focused education policy. Ironically, environment education is more actively implemented at informal institutes rather than formal ones. Environment education at schools is based on the school curriculum, but at informal educational institutes enjoy much more freedom in choosing learners, places and programs. Among them, the place is one of the most important factors of environment education. Therefore, in order to maximize the goal of environment education in this study, a specified program was developed and applied to a certain place to investigate its features and effects. Also the program was checked if it reflexes the environment education goal by using environment education program analysis frame. The results are as follows; according to the analysis of the program, the program was most effective for the two goals of offering hands-on experience and presenting motivations. The second most effective result of the program lied in the goal of knowledge, functions, value and attitude. And the teachers who used this program concluded that, when the program was applied to unmanned islands, offered stronger motivation due to their natural surroundings. Furthermore, direct experience is recommended because it can give us better conditions to collect data and to enhance interpretation ability.

To promote use of nutrition labels, degrees of awareness, use, and satisfaction of nutrition labeling on eating-out menus were investigated by a self-recorded questionnaire from May to July 2010 in 629 participants who visited four bakery chains (n=409) and three ice-cream chains (n=220) located in Daejeon. Of the subjects 53.4% were female, 68.8% aged 20~29 years, and 59.3% visited bakery or ice-cream stores 1~3 times per month. Only 38.2% of participants had knowledge of nutrition-labeling mandates for eating-out menus, and 74.9% had seen labels before in bakery and ice-cream stores. Most subjects understood calorie amount and daily value of sodium very well, but they failed to understand the meaning of daily value. Only 21.2% of the subjects understood nutrition label information completely. Of the participants, 46.7% read nutrition labels in bakery or ice-cream stores when purchasing. Among the subjects who read the labels, 77.2% (36.1% of total subjects) referred to the label information when selecting a menu and 46.9% (21.9% of total subjects) had experienced altering their menu choice based on the information. Exactly 53.3% of subjects answered they did not read nutrition labels since they were not interested or had no time, or because the labels were not noticeable. Satisfaction of the place, timing, and format of nutrition labels at bakery and ice-cream stores fell below average overall. Many subjects wanted trans fat and cholesterol to be added to the labels. In conclusion, degrees of perception, use, and satisfaction of nutrition labels at bakery and ice-cream stores were still low. More effective publicity and consumer education about nutrition labeling will be necessary, and bakery or ice-cream companies should make efforts to improve nutrition labeling such as providing format and place.

As people are getting interested in themselves ever than before, the value of culture industry which can satisfy their emotions has been considered much more important. According to this, in terms of the 'space', it is better to represent 'space' not just as a functional space, but the human-centered and making human and nature together. In this society, the most human-centered design can be achieved by pursuing value which is friendlier to nature. And it is sure that the interior design that completes life quality as well as emotions of human will be common in near future. There already has been a try 'Green interior' in subway station in variety ways, and now it is needed to make indoor display in Seoul subway station different in order to satisfy human emotions. If culture space in Seoul subway station applied eco-element interacts with indoor environment, it is surely expected that people have better feeling on subway station as well as help eliminate negative elements which underground have had. In culture space, there are many advantages for displaying space into 'nature', that is, natural space represents the best comfortable and agreeable space, and future-oriented design when it gets interacted with environment. Application of 'Green interior' in Seoul subway station makes special place ness by its symbol and image, so that it derives people to have more natural and comfortable movement distance in subway station, offers more comfortable and cozy place as well. Furthermore, it makes people very moved by experiencing the most special culture space that they have ever had.

In binary digital transmission system the band-limiting is required for the better transmission efficiency. But in the case of band-limiting the intersymbol-interference (ISI) usually takes place. In this paper, in an attempt to design band-limiting filter which has minimum ISI and maximum stop-band loss, first, making use of analog filter by combining Binary Transversal Filter (BTF) and analog filter (4th Butterworhfilter), we found the value that minimizes ISI phenomenon by getting step response of rectangular pulse resulting from BTF in time domain. Second, we found filter characteristic we want to in frequency domain for band-limiting and minimized the error. And then we obtained resistor value (Tap coefficient) in order to design algorithm for optimum filter. Also we showed the example of simulation in case we established the resistors with 3,5 and 7 respectively. With 7 resistors set, we identified that the ripple of about minus 30dB was taken place.

The useful practical land shall be reserved when an artificial land covers the railway and road. However, the problem is that since the artificial land places directly on the top of noise sources likely on the railway and road there will arise the weak points, noise and vibration. On this study based on creating the artificial land on the top of a railway vehicle base and placing a tenement on that land, it was comprehended the noise influence from the railway car through the simulation. In order to secure the input value for the simulation, at first measured the noise condition of the railway station building and the railway vehicle base. The output value for the railway station building (place A) was around (53.6~57.6) dB(A), the equivalent continuous sound level for an hour, and for the railway station building (place B) it was around (63.7~68.9) dB. The maximum outdoor noise of the tenement on the artificial land was measured as 64.1 dB(A) under the fixed condition on the simulation modeling. The built purpose of placing the artificial land to prevent the noise influence from the railway met the expectation to be less influenced on the tenement. Rather, because of placing the artificial land the noise level on the lower space could be increased so there requires having a noise control.

The purpose of this study was to research buying behavior and home fashion preferences based on housing size. The target consumers were Korean women, aged 20~40s who reside in the Seoul & Kyunggido areas. We distributed questionnaires to 650 women. However, only 600 questionnaires were used for the statistical analysis. Data analyses were conducted with SPSS program on the frequency, Chi-square test, cluster analysis, t-test and ANOVA. The results of this study are as follows: 1. The considering factors for purchasing such as brand, trends coordinating existing furnishings with new products and functionality were significantly associated with housing size. The buyers who reside in bigger size homes. over 40 pyung place higher value on brand name, trends. or coordinating existing furnishing with new products than residents in smaller units. However, women who live in smaller units place higher value on functionality when purchasing home fashion products. Considering factors such as brand, trend, and materials were also significantly associated with segmented age group; 40~49 age group considered brand, trend, and materials more than 20~29 age group. The group who are highly interested in home fashion considered design/color, rand, coordination, and functionality than the group who are low interested in home fashion. 2. Residents in over 40 pyung homes buy home fashion products at department stores, while residents in less than 39 pyung homes buy them at discounted store. 3. Respondents preferred solid colors more than patterns. However, they favored character pattern for textile bedding products for their children. 4. there is also a statistical difference in preferences for types of window treatments between large ad small housing sizes. Residents living in over 40 pyung preferred tie-back/cottage curtain, while residents living in less than 29 pyung preferred Roman shade style.

In this thesis, we inquire into teaching method of decimal fraction concept in elementary mathematics education based on measurement activity. For this purpose, our research tasks are as follows: First, we design a experimental learning-teaching plan of 'decimal fraction' unit in 4th grade textbook and verify its effect. Second, after teaching experiment using experimental learning-teaching plan, we analyze the student's status of understanding about decimal fraction concept. As stated above, we have performed teaching experiment which is ruled by new lesson design and analysed the effects of teaching experiment. Through this study, we obtained the following results. First, introduction of decimal fraction based on measurement activity promotes student's understanding of measuring number and decimal notation. Second, operator concept of decimal fraction is widely used in daily life. Its usage is suitable for elementary mathematics education within the decimal notation system. Third, a teaching method of times concepts using place value expansion of decimal fraction is more meaningful and has less possibility of misunderstanding than mechanical shift of decimal point. Fourth, teaching decimal fraction through the decimal expansion helps students with understanding of digit 0 contained in decimal fraction, comparing of size and place value. Fifth, students have difficulties in understanding conversion process of decimal fraction into decimal notation system using measurement activity. It can be done easily when fraction is used. However, that is breach to curriculum. It is necessary to succeed research for this.

The research for a 3-axial accelerometer sensor has increased dramatically in the fields of cellular phone, PDA, etc. In this paper, we develop a human walking detection algorithm using 3-axial accelerometer sensor and a user interface system to show the activity expenditure in real-time. To measure a walking number more correctly in a variety of walking activities including walking, walking in place, running, slow walking, we propose a new walking number detection algorithm using adaptive threshold value. In addition, we calculate the activity expenditure base on counted walking number and display calculated activity expenditure on UI in real-time. From the experimental results, we could obtain that the detection rate of proposal algorithm is higher than that of existing algorithm using a fixed threshold value about $5{\sim}10%$. Especially, it could be found out high detection rate in walking in place.
