The study analyzes reviews of hardware products, customer service products, and products that take the form of a convergence of hardware and cloud services in ICT using text mining. We derive keywords of each review and find the differentiation of words that are used to derive topics. A cluster analysis is performed to categorize reviews into their respective clusters. Through this study, we observed which keywords are most often used for each product type and found topics that express the characteristics of products and services using topic modeling. We derived keywords such as "professional" and "technician" which are topics that suggest the excellence of the service provider in the review of service products. Further, we identified adjectives with positive connotations such as "favorite", "fine", "fun", "nice", "smart", "unlimited", and "useful" from Amazon Eco review, an integrated product and service. Using the cluster analysis, the entire review was clustered into three groups, and three product type reviews exclusively resulted in belonging to each different cluster. The study analyzed the differences whereby consumer needs are expressed differently in reviews depending on the type of product and suggested that it is necessary to differentiate product planning and marketing promotion according to the product type in practice.

최근 각종 사물인터넷 제품이 시장에 출시되면서 관련 업체들은 시장 선점을 위해 표준화 플랫폼 분야에서 경쟁을 벌이고 있다. 또한 이동통신 3사를 중심으로 가정용 사물인터넷 서비스를 앞 다투어 출시하면서 시장을 뜨겁게 달구고 있다. 대표적 출시된 서비스는 스마트홈 관련 서비스가 있다. 이동통신 기반 사물인터넷 서비스는 초기 단계에 머물고 있으며 지속적으로 다양한 서비스가 출시될 것으로 예상된다. 이러한 시점에 이미 출시된 서비스를 중심으로 사물인터넷 서비스에 대한 선호도 분석을 기획하게 되었다. 새로운 제품이나 서비스가 출시되는 경우에 잠재적인 구매자들이 제품 및 서비스가 어떠한 속성에 영향을 받아 그 제품이나 서비스를 선택하게 되는지에 대한 연구는 연구자에게 매우 흥미로운 주제이다. 따라서 문헌분석과 시장조사를 통해 사물인터넷 서비스를 고찰하여 선호도 분석 개념모델을 완성하고자 한다. 또한 이동통신 3사에 근무하는 직원(전문가)를 중심으로 설문을 통해 선호도 분석을 하고자 한다. 분석결과를 바탕으로 연구의 한계와 이론적 실무적 시사점을 제시하고자 한다.

The purpose of this study are two the first is to identify the positioning of product design and analyze its functional relationship with product development, manufacturing, marketing and sales in the comprehensive competitiveness evaluation model ; and the second is to estimate the determinants of QCI(quality competitiveness index), analyze the impact of product design on QCI, and compare the aforementioned results for the seven industrial sectors and the five product patterns. For this empirical analysis, this study surveyed 400 Korean manufacturing firms during August-October 2003. The major empirical findings are summarized as follows : First, the hypothesis on the positive effect of product design on QCI is accepted at a highly significant level (p < 0.001) for all : the manufacturing sector, seven industrial sectors, and five product categories. Second, the correlation analysis and factor analysis lead to the result that the effect of product design on QCI is estimated to be relatively very low, in comparison to those of product functionality and basic performance on QCI. These findings imply that Korean manufacturing sector has been still in the prematured stage at which product design has not played an important role yet. This study concludes that product design in line with other functions (product development, manufacturing, marketing, and sales) should make a good contribution to the improvement of QCI in the future.

For better understanding the relationship between consumers' perception and sensory characteristics of products, diverse types of rapid sensory profiling technique have been suggested as alternatives to conventional descriptive analysis. Among these, check-all-that-apply (CATA) method has gained popularity for studying consumers' perception and intuitive responses to products due to their simplicity, speed, and ease of use. CATA method has been used to gather consumers' perception derived from sensory characteristics of products as well as consumers' emotion responses to products in recent years. Moreover, many researchers reported that CATA method can be used to provide valuable information for product optimization by applying a penalty analysis and collecting responses to ideal product. Thus, this article reviews recent research using CATA in the field of sensory and consumer science and introduces practical applications to achieve various business objectives in food industry.

This research focuses on women in their 20s and 30s who have experience in consuming beauty products in the live broadcast of beauty products in China to find out the effects of consumers' consumption propensity on beauty product selection attributes. The data analysis is performed from April 29 to May 25, 2021 by using SPSSWIN 21.0 program for frequency analysis, factor analysis, reliability appraisal, technical statistical analysis, correlation analysis and multiple regression analysis. And the results of the study are as follows: According to the survey, the general characteristics are 20~25 years old, university, and the consumer price is between 500,000 and 1 million won. In terms of consumption propensity that the intrinsic pursuit of consumption, the impulsive consumption, the external pursuit of consumption were on a high average score which was 3.76, 3.63, 3.56 respectively, and in terms of the selection attributes of beauty products that the product intrinsic attributes, and the external attributes of products were on a high average score which was 3.91, 3.69 respectively. The external/internal attributes of beauty product selection attributes are all related to consumption propensity. According to the survey, the external pursuit of consumption, internal pursuit of consumption, and impulsive consumption of the propensity to consume all have a meaningful influence on the external/internal attributes of products. This result proves that the consumption tendency of beauty live broadcast consumers has a huge impact on the selection attributes of beauty products. In this regard, according to the consumption tendencies of Chinese women, the necessity of differentiated live-streaming marketing strategies for beauty products based on the characteristics of beauty product brands, categories, and designs has been proposed.

Better quality software can be made by eliminating the software product risk in the early stages. To achieve this task, a risk analysis system that can effectively track and manage risks that have severe effects on software quality is needed. The existing risk analysis systems have some weaknesses as they are applied to organizations. The major problems of those systems are that they require organizations to collect as much risk data at a time without providing a proper explanation and even without the support of a risk management process. This paper resolves those problems by developing a risk analysis system that offers methods of managing risks. In addition, the system provides the guidelines of which risks should be gathered for each step. The system also has functions to generate a range of strategy and analysis information on risks.
