Analysis about supply chain structure was achieved in product unit that is not 'business' dimension that is existent discussion target in surrounding and supply chain structure as that this study analyzes positively how supply chain structure according to business surroundings of product changes. This can do that analysis of product unit in synthetic supply chain management is essential when recognize the importance that supply chain management must consist by product special quality according to corporation's each product. Sort product environment and studied relation with supply chain structure to achieve study purpose hereupon. Structure variable of supply chain drew through existent literature study here. Executed question investigation for supply chain by product for study that is actual proof enemy, and figure method used analysis of variance (ANOVA) mainly. If summarize result of study, result that analyze relation between business environment of product and supply chain structure, according to business environment of product, showed that supply chain structure changes. Certified that relation of two group (environment group of uncertain product and environment group of stable product) of business environment of product and structure variable (that is number of participant of supply chain, lead time of supply chain, about administration's independence, response points of supply chain) of supply chain is significant relation all from all structure variables except number of participant of supply chain. Variable that express length of supply chain from structure Variable of supply chain is number of participant of supply chain and lead time of supply chain, and variable that display monitoring or trust aspect for supply chain is administration's independence degree and response points of supply chain. As analysis result, product that environment is uncertain is appearing more shortly than product that length of supply chain stabilizes, and also, monitoring or trust aspect for supply chain was proved that is consisting abuzzer than product that stabilize. Therefore, showed that put essential point in administration of 'hierarchy'putting first than 'market' when business environment designs supply chain structure in case of uncertain product, and proved that the other side business environment is focusing in administration way of 'market' putting first in case of stable product.

This study aims to examine the effects of consumption values on digital convergence products buying behavior. Especially, this study examines the nature of consumption values that differentiate incremental innovation products from radical innovation product. We first categorize the convergence products into incremental innovation products and radical innovation products based on the degree of innovation, and then study the differences of consumption values of each product group. The empirical research is conducted on the premise that the consumer's value can play an important role in the process of selecting convergence product types. Although some factors related to function value has been accounted much of, various consumer values have not been studied in the context of convergence product consumption behavior. This research assumes that consumer choice behavior is a function of multiple consumption values such as functional value, social value, emotional value, and epistemic value. The result shows that consumption values of digital convergence products are made up of 4 consumption values-emotional, epistemic, social and functional values. Also, these consumption values affect the purchase intention of consumers. Purchase intention of radical innovation convergence products is affected by emotional value, epistemic value, and functional values. Purchase intention of incremental innovation convergence products is affected only by functional value. Demographic variables such as sex, age and income don't have influence on purchase intention. Our findings suggest that choice behavior of digital convergence product is influenced by several consumption values. Managerially, our result emphasize that convergence products must satisfy the consumption values that consumers are seeking in order to be successful in the market. the theoretical and practical implications of these findings are discussed as well.

A large number of functional living products are being produced for eco-friendly or health-promoting purposes. In the manufacturing process, such products could be adulterated with raw materials with high radioactivity, such as monazite and tourmaline. Thus, it is essential to manage raw materials and products closely related to the public living. For proper management, an accurate radioactivity data of the processed products are needed. Therefore, it is essential to develop a rapid and validated analytical method. In this study, the concentration of the radioactive $^{238}U$ and $^{232}Th$ in building materials (e.g., tile, cement, paint, wall paper, and gypsum board) and living products (e.g., health products, textiles, and minerals) were determined and compared by ED-XRF and ICP-MS. By comparing the results of both methods, we confirmed the applicability of the rapid screening and precise analysis of ED-XRF and ICP-MS. In addition, $^{238}U$ and $^{232}Th$ levels were relatively lower in building materials than in living products. Particularly, $^{232}Th$ content in 6 of 47 living products exceeded (maximum $8.2Bq{\cdot}g^{-1}$) the standard limit of $^{232}Th$ content in raw material ($1.0Bq{\cdot}g^{-1}$).

The purpose of this study is to analyze the effects of risk and convenience on purchase intention in the IOT market, and I want to analyze the moderating effect of emotional consumption value. In this study, two products were selected from three product groups. There are three major methods of research. First, theoretical considerations. Second, survey analysis. Reliability analysis and factor analysis were performed using descriptive statistics using SPSS. Third, we measured changes of EEG according to in - depth interview and indirect experience. As a result of the hypothesis of this study, it was confirmed that convenience of use of IoT product influences purchase intention. Risk was predicted to have a negative effect on purchase intentions, but not significant in this study. This implies that IoT products tend to be neglected in terms of monetary loss such as cost of purchase, cost of use, and disposal cost when purchasing. In-depth interviews and EEG analysis revealed that there is a desire to purchase and try out the IoT product due to the nature of the product, the novelty of new technology, and the vague idea that it will benefit my life. The aesthetic, symbolic, and pleasure factors, which are sub - elements of emotional consumption value, were found to have a great influence. This is consistent with previous research showing that emotional consumption value has a positive effect on purchase intention. In-depth interviews and EEG analyzes also yielded the same results. This study has revealed that emotional consumption value affects the intention to purchase IoT products. It seems that companies producing IoT products need to concentrate on marketing with more emotional consumption value.

The purpose of this study is to research the effects of the same brand item sold online at different prices. To that end, the exploratory study is focused on four factors that influence price dispersion online is suggested. First, the products are divided into utilitarian products and hedonic products in line with the product concept, and laptops, washing machines are included in the utility concept products. Also the backpacks and sneakers are included in the hedonic concept products. A total of 400 effective objectives were selected and analyzed for each concept products, 200 objectives. The research analysis revealed that the price dispersion is significant relationship with an average price, the highest price, the lowest price, the year of release, the number of retailers, and the number of reviews in case of the utility concept product. On the contrary, in case of hedonic concept products, average price, highest price, lowest price, year of release, retailer, and reviews and ratings is found to be positively related to price dispersion. Based on these results, theoretical and practical implications are discussed about the influence price dispersion on marketing.

R&D projects for product development are crucial for ventures' growth and success. Current study summarizes existing studies that identify the relationship between startup ventures' R&D department, R&D investment, and R&D cooperation on product development performance, and highlights the effects of business model as well as the roles of R&D activities for product development project that have been traditionally emphasized. In order to consider the effects of business models that were not previously available, the effects of these factors on product development performance were comprehensively analyzed. The research results with 180 venture cases surveyed on venture companies in the growth stage in Korea, showed that the effect of product development project activities measured by R&D department, R&D investment and R&D cooperation on product development performance is not evident. However, the effect of business model on product development time and product development performance measured by product innovation was confirmed. In particular, it was found that the clarity and uniqueness of the business model interacted with the R&D investment to shorten the product development time and directly increase the innovativeness of the developed product. Based on these analysis results, the implications of this study, limitations of the study, and the future research directions were described.

Software product line engineering is a software reuse paradigm that helps organizations improve software productivity and quality by developing software products from reusable core assets. For the satisfaction of common and variable requirements among products in the product line, the core assets must be configurable according to the selection of variable features. Therefore, unlike software architecture model of a single product, product line architecture model must embed and express variabilities among the products. Many researches have proposed methods of embedding and expressing variabilities in the product line architecture models, but there are few comparative studies on the proposed methods. In this paper we discuss strong points and weak points of the proposed methods and compare expressiveness of the methods, which helps select a proper method.

Over 60~70% of the domestic soil contamination have occurred by petroleum products. B T E X including benzene, toluene, ethylbenzene, xylene and total petroleum hydrocarbon (TPH) have to be inspected for the contaminated soil by petroleum products. An accurate contamination analysis is necessary to estimate the are of contaminated soil and also establish an appropriate purification scheme. In this study, we analyzed a sectional TPH pattern for current domestic distributed petroleum products. Also, the TPH content was analyzed by compensating the defect of current Korea standard analytic methods for soil where the analytic range is just for $C_8{\sim}C_{40}$. The light distillate petroleum products such as gasoline and solvent 1 showed the maximum of 85% difference in the TPH content between the standard analytic and improved methods.
