The aim of this study was to evaluate the characteristics of muffin made with tagatose which substituted sugar. Moisture contents were measured and Texture Profile Analysis was carried out during 3 day storage. 3 types of muffin, T0 (no tagatose added, sugar was the only sweet taste source), T25 (tagatose : sugar = 25:75(w/w), and T50 (tagatose : sugar = 50:50(w/w) were prepared. As the tagatose contents increased, the Maillard reaction proceeded more, so the color of the muffin crust was darker. Moisture contents of muffins decreased during storage, up to 2 days of storage, moisture contents of T25 and T50 were higher significantly, but at the 3rd day of storage, no differences were detected among samples. In the texture profile analysis, hardness, chewiness and fracturability were higher as the tagatose contents increased. Springiness and cohesiveness did not show any differences between T0 and T25 significantly. In the sensory evaluation, T0 got the lower points on the crust color value, but the crust colors were not significantly different among samples. Other characteristics like crumb color, moistness, sweetness, flavor and overall acceptance were not different significantly. As a result, when synbiotic and low-calorie tagatose was partly added to muffin up to 50 % as sugar substitute, overall qualities of those muffins were not different with only sugar added ones, even moisture contents were higher but color was a little bit darker, so tagatose can be used on making healthy muffins successfully.

This study suggests a Korean fashion design education model through a comparison of the fashion design curriculum and education systems in the USA, Europe, and Korea. For this, a case study of fashion design curriculum and education systems in the USA was performed with literature reviews about education methodology and design process to develop creativity, following the prior study, A Comparative Study on Fashion Design in Europe and Korea. For the case study, 12 superior fashion design education institutions in the USA were chosen from fashionista (N.Y.) and the goals, the emphases, the constitution of the online curriculum of each undergraduate fashion design course were examined. As a result of this study, Korean fashion design education model (1+2.5+0.5 model), was proposed by integrating the education systems of the USA and Europe, as follow: First, Korean fashion design education institutions need to be characterized and the departments/majors should be gradually specialized by the major. Second, foundation courses prior to undergraduate courses or during the 1st year should be established to result in a multi- disciplinary basic education. Third, a project based major needs to be performed that connects fashion design subjects with their related subjects for 2 and a half years as of the $2^{nd}$ year. These projects can be progressed by problem-solving design process of problem-identification and brainstorming-research, analysis-design concept-design ideation, selection-design development, implementation-critical evaluation and solutions. Fourth, collaborative projects or integrated courses with related Liberal Arts or other art and design majors should lead to muliti-discilplinary education. Fifth, the chance of increased active industry-academy collaboration and actual employment or enterprise can be facilitated by the establishment of only the courses related to domestic or international internships during the $2^{nd}$ semester of the $4^{th}$ year.

In this study, indoor thermal parameters were measured to investigate the characteristics of thermal environments and 138 occupants were questioned to evaluate Korean thermal comfort in office building in winter. Thermal sensation was estimated by using PMV(Predicted Mean Vote) and ET*(New Effective Temperature) indices. Comparing present experimental result with international standards and that of other research, Korean thermal responses were discussed. Seasonal difference between summer and winter was also discussed. It was found that TSV(Thermal Sensation Vote) is more sensitive than PMV to the variation of temperature and that the measured percentage of dissatisfied is higher than PPD(Predicted Percentage of Dissatisfied) in real office building environments. By regression analysis, the following regression equation has been obtained; TSV=0.432ET*-8.814 and neutral temperature is $20.4^{\circ}C$ in this case. Thermal comfort range based on 80% satisfaction is also $19.4{\sim}22.4^{\circ}C$.

The purposes of this study are to analyze an argumentation between an astronomers group and a counter astronomers group that have concluded different results by using the same methods and to find an implication for applying to school science. For this study, two science research papers, which have been interpreted differently, were selected and analyzed in spite of observing same area in Titan and using same data process method. Their key issues are involved in interpretation and explanation, and the credibility of observed data. From this result, scientific argumentation accompanied with the credibility evaluation about the justification process of scientific explanation and experiment results needs to be developed.

In this paper, we study the performance eualuations of the FDDI Network, by mathmeticlal analysis and simulation, in which the Integrated Voice/Data transmission system with voice traffic in synchronous mode and data traffic inasynchronous mode.For the mean waiting times of Voice/Data packet, we use two-state of Marcov models for voice traffic with talkspurt and silenci state, and the data traffic would traffic would transmit at the silence state of voice traffic. By the mean wating times, we analyze the relations between synchronous and asynchronous mode. As a result, using Sync/Async mode with voice and data, voice was not under influnece of data traffic. and in the same time,data can be tanaxmitted in a short waiting time, too.

The purpose of this study is to research the characteristics of literature related to environmentally friendly for a village-focused green index. In order to make an assessment, keywords relating to green architecture were selected: environmental friendliness, ecology, sustainable, Noksaek (Green in Korean), green, and environmentally friendly. In addition, three keywords defining the scope of space were also selected: building, village, and city. Quantitative changes and contents of articles containing the keywords were analyzed. The result is as follows. First, 'sustainable' and 'ecology' were the terms most frequently used as parts of subjects and titles, respectively. Second, the studies relating to green architecture focused on villages mostly examine the actual conditions of the villages; criteria for environmental friendliness, analyses and evaluation of the environmentally friendly features of the village; and ways to establish a green, ecological, and sustainable village. Finally, when it came to establishing a village-focused green index, the environment, resources, and energy are shown to be very important elements. In addition, the term 'ecology' in a green index is shown to be significant for the management of the natural environment.

This paper describes a development of a portable physical activity monitoring system using two accelerometers to quantify physical activity. The system hardware consists of two piezoresistive accelerometers, amplifiers with gain of 30, lowpass filters with cut-off frequency of 15Hz, offset control circuits, one-chip microcontroller and flash memory card. In order to evaluate the performance of the system we acquired 3 channel data at 32 sample/sec from body-fixed accelerometers in chest and right upper leg. And then the acquired data were processed by MatLab on personal computer. We tried to distinguish not only fundamental actions which are steady-state activities such as standing, sitting, and lying but also dynamic activities with walking, up a stairway, down a stairway, and running. Five subjects participated the evaluation process which compare the video data with the measured data. As a result, the activity classification rate of 90.6% on average was obtained. Overall results showed that the steady-state activities could be classified from the low component of 3-axis acceleration signal and dynamic activities could be distinguished from frequency analysis using wavelet transform and FFT. Finally, we could find that this system can be applied to acquire and analyze the static and dynamic physical activity data.

Purpose: The purpose of this study was to compare the applicability of the Charlson Comorbidity Index (CCI) and Acute Physiology, Age, Chronic Health Evaluation III (APACHE III) to the prediction of the healthcare outcomes of intensive care unit (ICU) patients. Methods: This research was performed with 136 adult patients (age>18 years) who were admitted to the ICU between May and June 2012. Data were measured using the CCI score with a comorbidity index of 19 and the APACHE III score on the standard of the worst result with vital signs and laboratory results. Discrimination was evaluated using receiver operating characteristic (ROC) curves and area under an ROC curve (AUC). Calibration was performed using logistic regression. Results: The overall mortality was 25.7%. The mean CCI and APACHE III scores for survivors were found to be significantly lower than those of non-survivors. The AUC was 0.835 for the APACHE III score and remained high, at 0.688, for the CCI score. The rate of concordance according to the CCI and the APACHE III score was 69.1%. Conclusion: The route of admission, days in ICU, CCI, and APACHE III score are associated with an increased mortality risk in ICU patients.
