Purpose: The purpose of this study is to explore how customers perceive virtual mirror technology in the 4th industrial revolution environment. In particular, this study investigated how virtual mirror technology affects customer satisfaction and intention to use that are rarely examined in previous studies. Research questions include how proposed variables including sensory stimulation, enjoyment, product quality, telepresence, interactivity, and immersion affect satisfaction and intention to use and how satisfaction affects intention to use. Research design, data and methodology: This study conducted an online survey and applied factor and regression analyses to test hypotheses. Results: The results of this study found that effects of sensory stimulation, telepresence, and immersion on satisfaction were significant, while effects of enjoyment, product quality, and immersion on intention to use were significant. Therefore, variables affecting satisfaction and intention to use were different, while effects of immersion were significant both on satisfaction and intention to use. Conclusions: This study concluded that the role of virtual mirror technology helps customers determine product quality and increase satisfaction level, while it also helps customers enjoy shopping and increase intent to use the service. The results of this study provide how to foster better relationship with customers by applying advanced technologies.

In this study, with the goal of developing a deep learning-based product recommendation model for effective matching of influencers and products, a deep learning model with a collaborative filtering model combined with generalized matrix decomposition(GMF), a collaborative filtering model based on multi-layer perceptron (MLP), and neural collaborative filtering and generalized matrix Factorization (NeuMF), a hybrid model combining GMP and MLP was developed and tested. In particular, we utilize one-class problem free boosting (OCF-B) method to solve the one-class problem that occurs when training is performed only on positive cases using implicit feedback in the deep learning-based collaborative filtering recommendation model. In relation to model selection based on overall experimental results, the MLP model showed highest performance with weighted average precision, weighted average recall, and f1 score were 0.85 in the model (n=3,000, term=15). This study is meaningful in practice as it attempted to commercialize a deep learning-based recommendation system where influencer's promotion data is being accumulated, pactical personalized recommendation service is not yet commercially applied yet.

Purpose: In Part 1, the purpose of this study is to examine how a used product provider optimizes a company's profits by comparing an extended warranty to a used product only when selling a product and what it provides later. In addition, in Part 2, an empirical study can confirm the structure in which extended guarantees can work effectively by grasping consumers' purchase intention according to the time of sale of extended guarantees, which is the basic premise of the analysis model of Part 1. Methods: This study aims to conduct not only analytical studies but also empirical studies applying various statistical analysis methods using questionnaires targeting customers and potential consumers who have subscribed to extended warranty services. Results: The study showed that the profits of companies providing extended warranty services were proportional to the coefficient of the extended guarantee service value, so it is necessary to create an environment in which the effect of extended guarantee services can be well realized. In the empirical model, the higher the emotional and economic benefits are perceived, the higher the purchase intention according to the future purchase of extended guarantees. Conclusion: Through this study, various problems that may be caused by the structural diversity of the supply chain providing extended warranties in the future can be viewed and contribute to the theoretical foundation for strategic understanding.

This study aims to analyze the factors influencing exports of agricultural products(HS01~HS24) from China to Korea by estimating the gravity model with panel data from 31 provinces in China. The results of the empirical analysis from the panel Tobit model are as follows: The effects of GDP and GDP per capita on agricultural exports are reversed, but their impacts are different on exports of each product, notably HS03, HS07 and HS20. As expected, distance decreases Chinese agricultural exports, and the impact of the relative exchange rate variable is also statistically significant, although it differs from product to product. However, differences in latitude, which considers the heterogeneity of climate and agricultural production conditions between Korea and each Chinese region, does not seem to affect agricultural exports to Korea. The road length, which affects the logistical conditions of each province in China, is not statistically significant either. On the other hand, increases in the number of Chinese visitors to Korea raises the amount of Chinese agricultural exports, including exports of HS03 and HS20. The results also shows that after the Korea-China FTA agreements, agricultural exports have actually decreased, especially exports of non-processed agricultural products, such as HS07.

The purpose of this study was to investigate product evaluation on consumer's buying behavior of domestic & imported golf wear brands. The questionnaires were sent to 200 consumers who play golf. The 119 data were analyzed by mean, t-test, ANOVA and chi-square. The results of the study were as follows: There were significant differences on consumers' evaluation of apparel quality on fabric and style between groups. Consumers evaluated that the imported golf wears made of more soft, light and unique fabric than domestic, and had a unique and characteristic style. The evaluation of apparel quality according to demographic information has significant difference. Consumers(46-55 ages, business managers and professional) evaluated imported brands were made of soft and light fabric. Consumers(business managers) buying imported brand evaluated dry-cleaning was inconvenient. Consumers who engaged in service industry evaluated domestic brands were easy to coordinate with other items.

Economic crisis in 2008 has changed South Korean market including furniture related field. Owing to Subprime Mortgage Crisis, new economic order, in other words, New Normal was established. Low growth rate, low interest, high unemployment rate, high risks, regulation strengthening, and all that sort of negative things have became generalized. South Korean economy has developed drastically since the Korean War, however recent economic crisis and Internet and smart phone have leading roles in shaping new consumption market. In a way, furniture market has expanded despite economic recession. Total service for housing is suited to South Korean consumers and shortened Product Life Cycle induces consumers to buy more furniture. In addition, Internet and smart phone allow people to show off their private spaces to unspecified masses. As a result, consumer prefers inexpensive and expendable furniture. It is certain that furniture market makes quantitative growth, but qualitative sides are questionable. Even though the study is focused on the existent circumstances, It will help to find out the proper ways of future furniture market in South Korea.

For over a decade, research and development on submerged hardware in continuous galvanizing pots has been carried out at Teck's Product Technology Centre. The outcome of numerous laboratory tests and field trials has demonstrated that dissimilar materials with comparable surface hardness are most suitable for the manufacture of roll bearings. Wear debris can be easily retained in bearings made of the same material, thereby negatively affecting bearing performance and service life. Bearings made of the same materials are also vulnerable to catastrophic failures. The dissolution of iron from the coated strip creates an iron-rich zone associated with a high concentration gradient in the vicinity of the sink roll. Consequently, the sink roll becomes a preferential site for dross pick-up. In operations involving extremely high temperatures, such as in Galvalume production, the material selection for pot hardware is immaterial to the final corrosion product of the hardware and the pick-up on the hardware.

In the telecommunication industry, estimation of the cost of network facilities is very important since depreciation cost of the facilities accounts for a large portion of the product cost. Moreover, cost estimation in the industry becomes more difficult because of increasing indirect cost upon digital convergence, expanding multi-purpose facilities, complexity of service product, etc. Nevertheless, not much seem to have been done in improving estimation methodology of the cost of network facilities. As a result, the quality of cost information on network facilities has deteriorated, and now even decision-makers in the industry dismiss the information. Recently, two major telecommunication companies adopted a new network cost estimation method to deal with the issue. In this paper, we study the concept of new cost estimation method and the procedure to develop and apply it. We also suggest the method to carry out the cost allocation using Matlab which is more efficient and time-saving than other commercial cost calculation packages.
