Online customer review data can be easily collected on the Internet and also they describe sentimental evaluation of a product in different aspects. Previous sentiment analysis studies evaluate the degree of sentiment with review data, which may have multiple sentences describing different product aspects. Since different aspects of a product can be described in a sentence, the proposed method suggested analyzing a sentence to build a pair of a product aspect terms and sentimental terms. Bidirectional LSTM and CRF algorithms were used in this paper. A pair of aspect terms and sentimental terms are evaluated by pre-defined evaluation rules. The paper suggested using the result of evaulation as inputs of QFD, so that the quantified customer voices effect on the requirements of a new product. Online reviews for a hair dryer were used as an example showing that the proposed approach can derive reasonable sentiment analysis results.

소프트웨어 아키텍처 (Architecture)를 설계하는데 있어서 소프트웨어의 품질속성(비기능)을 반영하는 것은 중요한 일이다. 하지만 품질속성은 정성적으로 분석되기 때문에 아키텍처 설계에 명확히 반영하고 구조화하는 것은 어려운 일이다. 따라서, 본 논문에서는 QAW(Quality Attribute workshop) 방법론을 통하여 도출된 품질속성들을 기반으로, 아키텍처를 설계하는 ADD(Attribute Driven Design) 방법론을 임베디드 소프트웨어 환경에 맞게 재구성하였다. 임베디드 소프트웨어 환경에 적합하게 수정된 프로세스(Process)와 적용된 실제 사례를 소개하였다. 또한 적용 결과를 바탕으로 향후 개선 방향을 도출하였다.

The purpose of this study is to suggest the measures to measure the shopping satisfaction and to increase the shopping satisfaction. We conducted surveys and conducted empirical analysis on Chinese tourists visiting duty free shops in Busan using direct survey method. The results of this study are as follows. First, factor analysis for subdividing the duty - free choice attribute was analyzed as store attribute, product attribute, and service attribute. Second, based on this analysis, the effect of each attribute on shopping satisfaction showed statistically significant positive results. Third, the analysis of the relative size of the effects of analytic attributes on satisfaction showed that store attributes were the highest. That is, the quality of duty-free shops, services, and products increases overall shopping satisfaction. Therefore, it can be said that the strategy implementation that improves the quality of the attributes affecting the satisfaction is expected to contribute to the improvement of the management performance, and suggests the management implications for the activation of the operation of the duty - free shop. Future studies will be more meaningful if more variety of shopping places are studied.

In this paper, we study the relationships between organization characteristics and desired software quality attributes of enterprise systems. We collected data from three client organizations in three different domains (auto manufacturer, insurance services firm, and government agency) that adopted enterprise software of the same software vendor. Our analysis discovers that capability is a more important attribute to the manufacturing and insurance firms than the government agency. Usability is ranked the highest among other attributes for the government agency and reliability for the manufacturing firm. The relationships identified in this study will help enterprise systems vendors predict their customer needs and, ultimately, increase effectiveness and efficiency in their software development processes. Such findings will be specially useful when software vendors develop enterprise software for a venture firm by enabling them to meet the customer needs customized by the organization haracteristics while staying within the incubating firm's limited budget.

Recently, construction industry shows active expansion in overseas construction market. But the active work limited in construction work, on the other hand, design-drawing work is evaluated shortage of competitive power. So this study aim to improve the competitive of 'domestic design-drawing work'thorough objective evaluation. Objective evaluation is consist of 'design attribution'. Design attribution is based on the execution drawing and complement by existing reasearch, expert interview. And then, list up the 'design attribution' evaluation list to carry out a survey targeting hands-on worker. Survey is consist of 'Likert 5-point scale, FMEA method'. As a result, construction company and design company show different opinions in both relative position evaluation and importance evaluation.

The purpose of this study is to examine the effect of the quality of performance on audience satisfaction, and to verify the mediating effect of service value and traditional image in this process. The subjects of this study included 211 male and female adults who experienced the Korean opera performance in Seoul, Korea in October. Collected data was used as a model of path coefficients obtained through analysis of covariance structure and hypothesis test. As a result of verification, program quality, physical environment quality, and quality of the stage performance perceived by the audience showed a statistically significant positive correlation with performance experience attributes. The path coefficient between performance attribute and service value, performance experience attribute and traditional image were also positively and statistically significant. Further, the path coefficient between performance experience and audience satisfaction showed a positive relationship. The service value and traditional image, service value and audience satisfaction, and the path coefficient between traditional image and audience satisfaction were statistically and positively significant. Finally, all hypotheses were adopted and study results confirmed the effect of service quality and experience attributes on audience satisfaction for the popularization, modernization and marketing strategy of the Korean opera. In this process, it is meaningful to verify the role and function of service value and traditional image.

Semiconductor deposition equipment is an important example of Complex Products and Systems (CoPS) and requires in-depth understanding of user requirements. For this reason, we analyzed and compared users' and producers' perspectives on the quality attributes of semiconductor deposition equipment using the Kano model. The results show that the patterns of users' perspectives were different from those of producers. Out of 22 level-2 quality attributes, producers evaluated all 22 attributes as attractive qualities, but users evaluated only 6 as "attractive," 10 as "indifferent," 2 as "must have," and 4 as "other." Although all quality attributes were attractive for producers, only those related to reliability were attractive or must-have qualities, and all others were "indifferent." This result implies that the perspectives on quality attributes may be different between users and producers, and producers should revise their perspectives and strategies. In addition, the results support the characteristics of CoPS suggested by literature implying that performance is more important than economies of scale and cost reduction. It is suggested that producers of semiconductor deposition equipment strategize their approaches to users by considering the characteristics of CoPS.
