The purpose of this study was to develop a housing choice behavior program to cultivate housing value orientation among middle-school students. The importance of cultivating housing value orientation in middle school was examined by investigating the relationship between housing value orientation and housing choice behavior, following which a program was developed to cultivate housing value orientation based on various housing values. Housing choice behavior was defined as selecting the ownership type, housing type, housing size, and neighborhood environment of housing, and the program was developed in 12 sessions to understand housing values and cultivate housing value orientation through learning housing choice behavior. The features of this program were as follows. First, although housing choice behavior is not covered in middle-school home economics, the 2015 revised national curriculum and current middle-school textbooks were analyzed and developed in consideration of the level available in schools. Second, it was possible to develop a housing value orientation that encompasses various housing values, including activities used to consider such values as the basis for housing choice behavior by each sessions. Third, the program was meaningful in that it developed practical problem-solving and living independence skills through learning activities, including available sites, experience cases, and housing welfare that cannot be experienced directly or indirectly.

Today, false news is increasing in volume, and fashion news often circulates uncritically. Therefore, an evaluation framework is needed to determine whether fashion news is accurate or good. In journalism, the judgment of good news is made through the criterion of news value factors. These factors are the criteria for assessing the likelihood of an event being reported in the news. Through the study of news value by various journalistic scholars, this study selected nine news value factors applicable to the value measurement of fashion news as the framework of analysis. Based on this, after analyzing the actual news on online fashion media, new characteristics and content were reconstructed for fashion news. As a result of the study, it was finally selected that the crucial factors were: expertise, social importance, timelessness, conflict, and negativity for measuring the value of fashion news. To assess the news value of fashion accurately, this study found that reconceptualized news values are needed, which are different from the news values of general journalism. The study is meaningful in that it explores elements and content for the development of a theoretical framework for the qualitative evaluation of fashion news.

The recent patent wars in the information technology (IT) industry demonstrate the strategic importance of IT patents in the industry. In this paper, we adopt the lens of real options to study the value of IT patents for IT firms. Specifically, we examine the relationship between IT patents and firms' market performance. We also consider the moderating effect of the innovation orientation of firms' patent portfolios (exploitative vs. explorative). Based on a large panel dataset consisting of 697 firms in US IT industries, our results suggest that the impact of IT patents on firm value (as measured by Tobin's q) is positive and significant. Further, we find that this impact varies, depending on the innovation orientation of firms' patent portfolios. IT patent portfolios with higher levels of an exploitative orientation are associated with higher firm value, compared to those with a lower exploitative orientation. This study highlights the value of employing real options theory as the underlying mechanism in understanding the impact of patents on firm valuation. Future researchers can adopt the real options lens to identify and empirically examine the role of other factors that may affect the value of patents and other investments exhibiting real option characteristics. While our paper answers some questions about the value of patents in the IT industry, it also raises a number of additional new questions. As such, we hope that it will generate more research on this important topic.

The purpose of this study is to evaluate the attributes of consumers global luxury fashion brands and to find the impact of consumer value, meaning the social and pleasure values derived from brands on product purchase involvement. The method in this study was analysis of a total of 298 responses to a questionnaire. The results indicate, first of all, that among the attribute evaluations of global luxury brands, traditionality and splurge affect purchasing involvement. However, prestige and originality were found to have no influence on purchasing involvement. Second, the responses to the questionnaire indicate that social and pleasure values had a statistically significant effect on purchase of luxury brands. Third, the value of cross-group attributes evaluation and consumption value to differences in purchase involvement has had statistically significant results. In conclusion, the traditional and Splurge natures of the luxury global fashion industry's brand, social consumption value and pleasure consumption value affect the level of purchase involvement. This underscores the importance of attribute Evaluation(traditional and splurge) and consumption value(social and pleasure) when planning consumer marketing strategies for global luxury fashion brands in the future.

The previous researches have addressed the importance of service quality, customer perceived value, and customer satisfaction, but the precise nature of the interrelationship that exist between these constructs still remains a key issue. This study extend the previous researches by developing a conceptual framework linking all of these constructs, additionally including service costs and customer expected value, in a business-to-business setting. The hypothesized model indicates that delivering high quality and lower costs service can create superior customer value and results in higher customer satisfaction. The authors test the hypothesized model on data obtained from power plant operators using structural equation modeling. The results suggest that service quality displays a stronger potential for creating customer value than costs consideration. In addition, the results reveal that managing the customer expected value is important for obtaining higher customer satisfaction.

The importance of intangible assets have increased unprecedentedly with the advent of the knowledge-based society. Investment in R&D has contributed to the rise of productivity and firm-value in the capital markets. but it is very difficult to determine the economic benefits of R&D investment, due to elusive link between time requirements and the realization of firm value from R&D investment. This study examines the differential effects of R&D expenditure and patents on firm-value by industry. Patents are intangible, proprietary rights that develops new products, plays a crucial role in market competition and results in research and development activities. If firms get patents, their R&D expenditure is assumed to be successful. The study analyzes whether successful R&D expenditure has a significant effect on the firm-value. The study considers two industries : high-tech industries and low-tech industries. These industries are expected to have different effect on R&D expenditure and firm-vale. The results of the study indicate that the successful R&D expenditure increased the firm-value. Successful R&D expenditure in high-tech industries more increased the firm-value more than that in low-tech industries.

This research has classified waiting times into the three different ones according to service offering process and investigated the antecedents and consequences of types of waiting times. A service provider's concern and customer involvement were modeled as antecedent variables and negative emotion and service value as dependent variables. The empirical results of the study are as follows. A service provider's concern had significant influences on all the three types of waiting times whereas customer involvement was found to affect preprocess-waiting and postprocess-waiting times. Preprocess-waiting time had a significant impact on both negative emotion and service value and inprocess-waiting time only affects negative emotion. However, postprocess-waiting time had influenced none of the variables. The findings illustrate an important role of concern and involvement regarding to a customer's perceived waiting time and relative importance of waiting types on negative emotion and service value. A summary of the results are reported and managerial implications are discussed.

Since randomness and uncertainties of design parameters are inherent, the robust design has gained an ever increasing importance in mechanical engineering. The robustness is assessed by the measure of performance variability around mean value, which is called as standard deviation. Hence, constraints in robust optimization problem can be approached as probability constraints in reliability based optimization. Then, the FOSM (first order second moment) method or the AFOSM (advanced first order second moment) method can be used to calculate the mean values and the standard deviations of functions describing constraints and object. Among two methods, AFOSM method has some advantage over FOSM method in evaluation of probability. Nevertheless, it is difficult to obtain the mean value and the standard deviation of objective function using AFOSM method, because it requires that the mean value of function is always positive. This paper presented a special technique to overcome this weakness of AFOSM method. The mean value and the standard deviation of objective function by the proposed method are reliable as shown in examples compared with results by FOSM method.

Background: The aim of this study was to research the importance of the neutrophil to lymphocyte ratio (NLR) in prediction of PSA recurrence after radical prostatectomy, which has not been reported so far. Materials and Methods: The data of 175 patients who were diagnosed with localised prostate cancer and underwent retropubic radical prostatectomy was retrospectively examined. Patient pre-operative hemogram parameters of neutrophil count, lymphocyte count and NLR were assessed. The patients whose PSAs were too low to measure after radical prostatectomy in their follow-ups, and then had PSAs of 0,2 ng/mL were considered as patients with PSA recurrence. Patients with recurrence made up Group A and patients without recurrence made up Group B. Results: In terms of the power of NLR value in distinguishing recurrence, the area under OCC was statistically significant (p<0.001) .The value of 2.494 for NLR was found to be a cut-off value which can be used in order to distinguish recurrence according to Youden index. According to this, patients with a higher NLR value than 2.494 had higher rates of PSA recurrence with 89.7% sensitivity and 92.6% specificity. Conclusions: There are certain parameters used in order to predict recurrence with today's literature data.We think that because NLR is easy to use in clinics and inexpensive, and also has high sensitivity and specificity values, it has the potential to be one of the parameters used in order to predict biochemical recurrence in future.

The purpose of this study was to analyze forest vegetation structure in Marugeum (the ridge line) area between Dakmokryeong and Daetjae in Baekdudaegan through vegetation classification, importance value, species diversity, and CCA using the data that were collected from 245 quadrates through Braun-Blanquet vegetation survey method from May to September in 2017. The results of the forest vegetation classification identified 8 vegetation units with Quercus mongolica community group at the highest level. Q. mongolica community group was classified into the Cornus controversa community, Buxus koreana community, Sasa borealis community, Abies nephrolepis community, and Q. mongolica typical community. C. controversa community was further classified into Quercus dentata group, Filipendula glaberrima group, Larix kaempferi group, and C. controversa typical group. The result of the important value analysis showed that Q. dentata had the highest importance value at 19.1% in vegetation unit 1 while Q. mongolica had the highest importance value at 22.7%, 38.3%, 25.6%, 41.3%, 27.9%, and 41.6% in vegetation unit 2, 4, 5, 6, 7, and 8, respectively, and L. kaempferi had the highest importance value at 27.6% in vegetation unit 3. As such, Q. mongolica species generally represented the communities of Marugeum (the ridge line) area of Dakmokryeong to Daetjae in Baekdudaegan. The results of species diversity showed that vegetation unit 1 and 2 were 3.305 and 3.236, respectively, which were relatively higher than other vegetation units. It was considered that this result was due to the influence of high emergence of present species. The results of the CCA analysis of the correlations between biotic environmental factors and vegetation types showed that vegetation unit 1 was mainly correlated with the megaphanerophyte ratio and vine plant ratio. In the correlations between abiotic environmental factors and vegetation types, vegetation unit 7 was significantly correlated with altitude. From the perspective of ecological management, vegetation unit 5 represented by B. koreana community was inhabited by a variety of plants due to the species composition and location environment due to the geological characteristics that are typical of limestone area. Vegetation unit 7 represented by A. nephrolepis community was typified as subalpine vegetation widely distributed by relict species and endemic species. We concluded that it is necessary to manage these vegetation units with an ecologically differentiated approach.
