Design optimization of a transonic compressor rotor (NASA rotor 37) using response surface method and three-dimensional Navier-Stokes analysis has been carried out in this work. Baldwin-Lomax turbulence model was used in the flow analysis. Two design variables were selected to optimize the stacking line of the blade, and mass flow was used as a design variable, as well, to obtain new design point at peak efficiency. Data points for response evaluations were selected by D-optimal design, and linear programming method was used for the optimization on the response surface. As a main result of the optimization, adiabatic efficiency was successfully improved, and new design mass flow that is appropriate to an improved blade was obtained. Also, it is found that the design process provides reliable design of a turbomachinery blade with reasonable computing time.

Previously, we developed a CHO cell line (CHO-OTC1-Al9) that expresses the first two enzymes in the urea cycle and exhibits a higher ammonia-removing ability and faster growth rate than a vector-controlled CHO cell line (CHO-neo-5). The current study was undertaken to develop a cell line with an ammonia-removing ability higher than the cell line developed previously. To accomplish this, CHO cell lines expressing the first three, first four, or all five enzymes of the urea cycle were constructed using a stable transfection method. Finally, the CHO-AS-16, CHO-AL-19, and CHO-Arg-11 cell lines expressing the first three, first four, and all five enzymes of the urea cycle, respectively, were selected and found to exhibit higher ammonia-removing ability than the CHO-OTC1-Al9 cell line. Among the three selected cell lines, CHO-AL-19 showed the highest ammonia-removing ability and highest cell viability at a higher cell density, with 40% and 15% lower ammonia concentration in the, culture media than that of CHO-neo-5 and CHO-OTC1-A19 cell lines, respectively. CHO-AL-19 also showed 44% and 10% higher cell viability than the CHO-neo-5 and CHO-OTC-Al9 cell lines, at a higher cell density, respectively. The ammonia concentrations in the culture media were expressed as the ammonia concentration/cell, and the CHO-AL-19 cells revealed 45-60% and 20% lower ammonia concentration/cell than the CHO-neo-5 and CHO-OTC1-Al9 cells, respectively.

232 internet sites in Yahoo and Empas were monitored to analyze what good contents of nutrition information on line have for the internet searchers. As the sites on line were disappeared frequently, all the monitored sites were selected on April 25, 2003. 3 disciplined personnels analyzed the contents of the selected sites by using self-developed monitoring format. The results are as follows. Most of sites were administered by the marketing companies and only 8% by public institutions, associations and school. Especially, most of the contents of the sites by marketing companies were advertisement about their goods instead of nutrition information. Only 42.6% of sites indicated the sources of nutrition information. Only 10.3% of site administrators responded about on-line questions quickly within 1 day. Moreover, 46% of sites were not conformed their answering periods. On the other hand, 94.8% of sites offered more than 1 feedback methods. Monitors checked purposes offering on-line informations plurally. Leading purpose was for advertising and marketing their goods(59.5%) and 47% of them were opened for offering food and nutrition information. They offered various informations at the same time. More than half of the sites had the menus for food and nutrition information and connected sites, but the other half of them only advertised their own goods. Positive sides from monitored informations were as follows : 'communicating informations easily' (8.7%) / 'definite informations for daily living' (7.2%) / 'beneficial informations for nutritional management' (4.6%) / 'new informations' (2.1%). Negative sides of offered information were ‘not enough to give scientific basis and/or to simplify special evidences too much’(60.8%) / ‘to exaggerate the contents’ (41.4%) / ‘not to indicate the notice of side effect and/or to advertise that there are not side effect from using their goods’ (34.1%).

Patient Navigation Program (PNP) is considered as an important implementation of health care systems that can assist in patient's treatment. Due to the feasibility of PNP implementation, a systematic reuse is needed for a wide adoption of PNP computerized system. SPL is one of the promising systematic reuse approaches for creating a reusable architecture to enabled reuse in several similar applications of PNP systems which has its own variations with other applications. However, stakeholder decision making which result from the imprecise, uncertain, and subjective nature of architecture selection based on quality attributes (QA) further hinders the development of the product line architecture. Therefore, this study aims to propose a quality-driven approach using Multi-Criteria Decision Analysis (MCDA) techniques for Software Product Line Architecture (SPLA) to have an objective selection based on the QA of stakeholders in the domain of PNP. There are two steps proposed to this approach. First, a clear representation of quality is proposed by extending feature model (FM) with QA feature to determine the QA in the early phase of architecture selection. Second, MCDA techniques were applied for architecture selection based on objective preference for certain QA in the domain of PNP. The result of the proposed approach is the implementation of the PNP system with SPLA that had been selected using MCDA techniques. Evaluation for the approach is done by checking the approach's applicability in a case study and stakeholder validation. Evaluation on ease of use and usefulness of the approach with selected stakeholders have shown positive responses. The evaluation results proved that the proposed approach assisted in the implementation of PNP systems.

In this paper, we investigate the signal to noise ratio (SNR) estimation performance of Cross quadrature amplitude modulation (QAM), which is being used for asymmetric digital subscriber line (ADSL), very high bit rate digital subscriber line (VDSL), and digital video broadcasting - cable (DVB-C), and has been found to be useful in adaptive modulation and blind equalization. At first, the symbol error rate (SER) performance of Cross QAM is analyzed in Rayleigh fading channel. Then we suggest error vector magnitude (EVM) based SNR estimation utilizing the selected constellation points having different types of decision region from one another, and verify that SNR estimation performance of each points have different performance pattern through simulation. From the simulation results, it has been found that when suggested selected constellation points are used for SNR estimation in Cross QAM, estimation performance is enhanced in additive white Gaussian noise (AWGN) channel or Ricean fading channel.

As the life styles have been changed in modern society and sports gave been emphasized for spending spare time and improving health condition, sports are regarded to lave a leading role to fashion as one of the prominent factors. This study is to analyze the gender-identity and how different levels of involvement in In-line skating affects clothing interests. 291 In-line skaters ranged in age from middle twenties to middle thirties were surveyed and measured for this study. MANOVA(multivariate analysis of variance), ANOVA(univariate analysis of variance), Cronbach ${\alpha}$ reliability, t-test, and correlation analysis were performed with SPSS 10.0 program on the selected data. The results of this study are as follow. There were no obvious differences in In-line skating clothing interests by gender of In-line skaters. There were, however, differences in the reasons for In-line skating, the hours to skate per week. Those whose purpose for skating was diet had more interest in style focused on expression. In case of skating for health, they showed interest in activity-functionality style and anti-deviation style. The group of In-line skaters who skated 15 to 18 per week gave more interest in activity-functionality style out of the clothing interest-factors. Those who had strong masculinity in gender-identity of In-line skaters were more involved in In-line skating. There were some differences in clothing interests according to gender-identity of In-line skaters. In regard of In-line skating clothing interest by involvement in In-line skating, those who had higher involvement in In-line skating had higher In-line skating clothing interest.

The purpose of this study was to provide data on the normative values of some clinically important soft tissue dimensions for adult Korean females with aesthetically beautiful facial profiles. Lateral cephalograms of 18 Korean female models, who were selected for their well balanced and aesthetic facial profiles, were evaluated. All cephalograms were taken with the subjects in a natural head position with the teeth in occlusion and the lips at rest. The means and standard deviations were determined and presented. In addition, comparisons with the previous studies were performed The results of the present study were as follows: 1. The upper and lower lips were posteriorly located in relation to the Ricketts' E line (Upper lip to E line: -2.08, Lower lip to E line: -0.04). 2. Both lips were more posteriorly located than those in the results of previous studies on Korean females selected by normal occlusion, but more anteriorly located than in the results of studies selected on an aesthetic basis. 3. The nasolabial angle for this sample was 101.03 degrees with a standard deviation of 8.47 degrees.
