The purpose of this study is to analyze the sensibility of the compound fashion image of contemporary fashion. The specific objectives were to analyze 1)the structure of meaning about fashion sensibility on 2)the difference of fashion sensibility by categories on 3)the difference of fashion sensibility by demographical aspects on 4)the consumer sensibility on the compound fashion image. For collecting data 55 stimulus and questionnaire which consisted of bi-polar 21 pairs adjective scale were contributed 675. The results were summarized as following : 1. Factors of fashion sensibility consist of estheticism, activeness, personality and feminity. And the meaning of fashion sensibility is young and personalty. 2. The man/woman and the past/present are highly estimated personality, the main/subcultural is activeness and the local/global is feminity of fashion sensibilities. 3. gender and age have high difference of the compound fashion image so they are important variance for fashion sensibilities. 4. Preference, purchase and quality are highly influenced by estheticism, pleasure is influenced by personality. The results of this study will be utilized in the clothing design for accepting customers' specific fashion sensibility about compound fashion image.

Response surface methodology (RSM) is used to investigate the complex coupling effects of different operating parameters on silicon growth rate in planetary CVD reactor. Based on the computational fluid dynamics (CFD) model, an accurate RSM model is obtained to predict the growth rate with different parameters, including temperature, pressure, rotation speed of the wafer, and the mole fraction of dichlorosilane (DCS). Analysis of variance is used to estimate the contributions of process parameters and their interactions. Among the four operating parameters that have been studied, the influences of susceptor temperature and the operating pressure were the most significant factors that affect silicon growth rate, followed by the mole fraction of DCS. The influence of wafer rotation is the least. The validation tests show that the results of silicon deposition rate obtained from the regression model are in good agreement with those from CFD model and the maximum deviations is 2.15%.

Purpose: The objective of this study was to analyze the effects of medical staffing level as bed-to-medical staff ratio on patient outcomes as length of stay (LOS) among hospitals in Korea. Methods: Two hundred and fifty one hospitals participated in the study between January and March 2008. Data for the study was requested by an electronic data interchange from the Health Insurance Review Agency in 2008. In data analysis, SPSS WIN 15.0 program was utilized for descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression. Results: The mean score for length of stay was 13.6 days. The mean of operating bed-to-nurse ratio was 7.93:1. The predicting factors for LOS were bed-to-nurse's aide ratio, bed-to doctor's ratio, severely ill patient rate, and hospital type. These factors explained 28.9% of the variance in patient outcomes. Conclusion: This study results indicate that the relationship between medical staffing level and patient outcomes is important in the improvement of the quality of patient care. Thus, improvements in the quality of the nurse practice environment could improve patient outcomes for hospitalized patients.

Color is an important factor in dental esthetics. Application of natural tooth color will not fail to produce pleasing results. But a standardized method of shade matching has not been adopted. If we are to overcome the color matching problem in dentistry, an understanding of the nature of color and light is essential. The purpose of this study was to compare the effects of different light sources and different background colors on the ability of observers to correctly match shades of artifical teeth. And observation was made to determine if the time spent in making a shade match was a factor in the correctness of the response. A test method was devised and 50 individuals made observations which were recorded and analyzed. $X^2$-test gave results indicating that the time factor had no effect on the response made. An analysis of variance showed the following effects significant at the five percent level; (1) light source (2) background color (3) subject. The following conclusions can be drawn from this study; (1) The time spent in making shade selection is not a factor in the correctness of the selections. (2) The light source used is an important factor in matching tooth shade; and there is no significant difference between the light sources in shade matching. (3) Under the conditions of this study, the greatest accuracy in shade matching was obtained on the brown background.

The goal of this study was to determine if there was a difference in leak pressure between esophageal-esophageal anastomosis and esophageal-jejunal anastomosis when using cadaveric porcine tissue. Leak pressures were recorded for esophageal-esophageal anastomosis (Group 1 [control group], n = 7), cranial esophageal-jejunal anastomosis (Group 2, n = 7), and jejunal-caudal esophageal anastomosis (Group 3, n = 6). Each anastomosis was performed using polydioxanone sutures in a simple interrupted pattern. Results were analyzed using one-way analysis of variance. Mean ± SD of the leak pressures for groups 1, 2, and 3 were 46.1 ± 15.9, 36.5 ± 13.6, and 50.9 ± 11.1 mmHg, respectively (p = 0.18). When the results from groups 2 and 3 were combined and compared to that for Group 1, the mean ± SD leak pressures were 46.1± 15.9 and 43.1± 14.2 mmHg, respectively (p = 0.67). These results provide preliminary evidence that the jejunum may be a suitable option for use in esophageal replacement surgery; however, future studies of in vivo factors influencing the integrity of esophageal-jejunal anastomoses, including histologic evaluation of esophageal-jejunal anastomosis healing, are needed.

This paper investigates the performance of interference-limited two-way transmission protocols in the Rayleigh fading channels. New lower bound of outage probability and approximate expression of bit error rate (BER) for three-phase two-way relaying (3P-TWR) protocol are derived in closed-form. These expressions are valid for arbitrary signal-to-noise ratio values, numbers of co-channel interferers and amajority of modulation formats employed in the practical system. Then a comparative study is developed for the performance of three two-way transmission protocols, i.e., direct transmission (DT) protocol, two-phase two-way relaying (2P-TWR) protocol and 3P-TWR protocol based on the asymptotic expressions of outage probability and BER. On the basis of the theoretical results, the thresholds on the strength (variance) of direct channel and target rate for the relative performance of different protocols are obtained and the effect of interferences at the terminal and relay on the relative performance is analyzed. The results present key insights on how to choose proper two-way transmission protocol with the knowledge of fading channels, required date rate and modulation format to optimize the system performance in the practical interference-limited scenarios. Simulation results are presented to validate the theoretical analysis.

This study proposes an optimal operational policy for a green supply chain (GSC) where a retailer pays an incentive for collection of used products from customers and determines the optimal order quantity of a single product under uncertainty in product demand. A manufacturer produces the optimal order quantity of product using recyclable parts with acceptable quality levels and covers a part of the retailer's incentive from the recycled parts. Here, two scenarios for the product demand are assumed as: the distribution of product demand is known, and only both mean and variance are known. This paper develops mathematical models to find how order quantity, collection incentive of used products and lower limit of quality level for recycling affect the expected profits of each member and the whole supply chain under both a decentralized GSC (DGSC) and an integrated GSC (IGSC). The analysis numerically compares the results under DGSC with those under IGSC for each scenario of product demand. Also, the effect of the quality of the recyclable parts on the optimal decisions is shown. Moreover, supply chain coordination to shift the optimal decisions of IGSC is discussed based on: I) profit ratio, II) Nash bargaining solution, and III) Combination of (I) and (II).

We compared the composition of phospholipid fatty acids (PLFA) to assess the microbial community structure in the soil and rhizosphere community of non-transgenic watermelons and transgenic watermelons in Miryang farmlands in Korea during the spring and summer of 2005. The PLFA data were seasonally examined for the number of PLFA to determine whether there is any difference in the microbial community in soils from two types of watermelons, non-transgenic and transgenic. We identified 78 PLFAs from the rhizosphere samples of the two types of watermelons. We found eight different PLFAs for the type of plants and sixteen PLFAs for the interaction of plant type and season. The PLFA data were analyzed by analysis of variance separated by plant type (P<0.0085), season (P<0.0154), and the plant type${\times}$season interaction (P<0.1595). Non-parametric multidimensional scaling (NMS showed a small apparent difference but multi-response permutation procedures (MRPP) confirmed that there was no difference in microbial community structure for soils of both plant types. Conclusively, there was no significant adverse effect of transgenic watermelon on bacterial and fungal relative abundance as measured by PLFA. We could reject our hypothesis that there might be an adverse effect from transgenic watermelon with our statistical results. Therefore, we can suggest the use of this PLFA methodology to examine the adverse effects of transgenic plants on the soil microbial community.

This study investigates the effects of the interplay of device types and the need for touch (NFT) on product attitudes and determines how the mental simulation of touch mediates such relationships. Specifically, we test the roles of instrumental and autotelic NFT in the moderated mediation effect of mental simulation of touch. We instructed the potential participants to shop for a leather jacket on a webpage. With a total of 152 data points from the responses of participants who used a laptop and a touch device that uses a direct-touch interface (e.g., tablets), we conducted descriptive statistics, analysis of variance, and PROCESS procedures using SPSS 20.0. The results show a greater mental simulation for touch when using a touch device than a laptop. When individuals' instrumental NFT is low, using a touch device while shopping online heightens mental simulation of touch, which impacts product attitudes. In particular, such a moderated mediation effect strengthens as the value of individuals' autotelic NFT increases. However, when individuals' instrumental NFT is high, a touch device cannot drive mental simulation for touch, increasing favorable attitudes toward the product.

Purpose : It is widely accepted that addressing multiple symptoms together is the preferred approach in assessment and intervention and results in reduced negative patient outcomes. Yet, there are few studies examining symptom clusters and their impacts on quality of life longitudinally in patients after heart valve surgery. Methods: A total of 101 patients were recruited from a tertiary hospital and were administered questionnaires (at 3, 6, and 10 weeks after the surgery) assessing participants' characteristics, cardiac symptoms, and quality of life. Factor analysis was used to identify symptom clusters. Hierarchical multiple linear regression was used to predict quality of life. Results: Participants were predominantly 70-years old or more with a mean age of 64.34. The two symptom clusters at 3 weeks after the surgery with education, gender, and occupation accounted for 76.3% of variance in quality of life. Conclusion: Symptom clusters containing various physical and psychological symptoms in patients after the surgery affected quality of life, and the relationship was significant at 3 weeks after the surgery. Because symptom clusters were identified in all three recovery periods, nurses need to acknowledge these clusters, rather than each symptom separately, and to utilize these in providing care and education and in promoting quality of life in these patients.
