In the new product development process, concept testing which screens ideas with the highest probability of market success is very effective in predicting the success of a new product. However, designers do not have accurate guidelines in new product development because the structure of cause and effect of consumers' preference - the most important part of concept testing - has not been provided as quantitative data. Therefore, the aim of this study is to present guidelines for new product concept development through applying means-end chain theory and product form theory which explains what kinds of benefits cause consumers to purchase a product and what kinds of design attributes meet the benefits. In this study, after reviewing means-end chain theory and product form theory, and developing a research model, guidelines for a concept product development (TV are provided through an empirical study.

Purpose - This study attempted to identify the value promotion clues that may operate as a consumer's motive, by shedding new light on consumer value and by reconstructing each variable analyzed through the means-end chain (MEC) theory. Research design, data, and methodology - In this study, 202 copies of effective questionnaires using the data of Yang and Ju (2012) were subjected to correlation, regression, and SEM. Results - All store selection attributes were verified as having a positive influence on the relationship quality. Although the store selection attributes were verified as exerting a positive influence on the relationship quality, according to the verification result of the mediating effect, consumer value was verified to be influenced only by the relationship quality instead of by the store selection attributes. Conclusion - As a result of path analysis on the proposed model after modification, it was verified that only product factor had a statistically significant positive influence and that social value was completely mediating between relationship quality and emotional value. It may be highlighted that the MEC theory concept would be applicable to the cause-and-effect relationship model.

Purpose - In the joint development of new products, buyers and suppliers exchange information to solve various problems. Uncertainty and ambiguity are typical examples. Uncertainty refers to the lack of information to solve the problem, and equivocality refers to the case where the information is interpreted in multiple processes in the process of providing the information. These uncertainty and equivocality cause new products to be delayed in their development and adversely affect quality. However, unfortunately, there is a lack of researches on how the uncertainty and equivocality of such concepts control the results of new product joint development. But, smooth communication and effective exchange of information is not emphasized only in the general organization. The importance of the new product joint development projects to achieve the two organizations' common goals becomes even greater. The purposes of this study are to analyse the effect of supplier's strategy on the NPD performance and moderating effect of uncertainty and equivocality. Research design, data, and methodology - In order to make a contribution to the lack of academic researches in Korea, this study collects data through questionnaires based on organizational information processing theory and previous studies, and conducts empirical analysis. Results - As a result, the product modularization strategy and the strategic supply chain relationship positively influenced the new product development performance - return on investment and ease of manufacturing. And the interaction effect of uncertainty and equivocality with supplier's strategy - product modularity strategy and strategic supply chain management relationship - reduces or negates the influence of product modularization strategy on new product development performance. Conclusions - This implies that it is important to control uncertainty and equivocality in order for the supplier strategy to have a positive effect on new product development performance. It also emphasizes the necessity of sharing information appropriately for companies that do not want to share the information as possible due to their fear of loss of competitive advantage in the joint development of new products. Because this kind of negative policy might let uncertainty and equivocality be happen in new product joint development process.

Increasing evidence regarding free radical generating agents and inflammatory processes suggests that accumulation of reactive oxygen species can cause hepatotoxicity. A short-chain analog of lipid hydroperoxide, t-butyl hydroperoxide (t-BHP), can be metabolized to free radical intermediates by cytochrome P-450 in hepatocytes. which in turn can initiate lipid peroxidation, affect cell integrity and result in cell injury.

The purpose of this paper is to investigate index numbers by conducting various comparisons among the widely used index formulas. The comparison is considered in three ways; 1) divergences in the magnitudes of index numbers due to the use of different formulas (Laspeyres, Paasche, Fisher, and Tornqvist); 2) the effect of selection of base year (fixed-year base vs. chain-type); 3) the degree of approximation of indirect to direct quantity index. The empirical application is to sawmills and planing mills industry of U.S. using a national time series data covering years of 1948-2000. The results show that the differences between Laspeyres and Paasche index can be substantial in some cases while the difference between Fisher and Tornqvist index is minimal. We also confirm that the selection of base year can cause significant divergences, especially when the variables undergo rapid price or quantity changes over time. We find that indirect quantity index approximates direct quantity index reasonably well in U.S. sawmill industry.

Objective: Thoracoscopic sympathicotomy is effective in treating not only palmar hyperhidrosis, but also axillary hyperhidrosis. But studies for axillary hyperhidrosis accompanying osmidrosis are few. We report the outcome of six axillary hyperhidrosis with osmidrosis with literatures review. Methods: Using a minimally invasive technique, thoracoscopic T3-4 sympathicotomy was performed. The results of sympathicotomy of third and fourth sympathetic chains of six patients from January 1999 to August 2003 for axillary hyperhidrosis with osmidrosis were reviewed. Results: All patients had a successful outcomes, their profuse sweating ceased. Two patients suffered from compensatory hyperhidrosis. Three patients disappeared or diminished foul odor but three patients complained remained osmidrosis. Conclusion: In the treatment of axillary hyperhidrosis, the sympathicotomy of T3 and T4 chain is an effective method but osmidrosis must be treated according to its cause.

The food cold chain refers to a technology and distribution supply chain applied to maintain a constant temperature suitable for the product from production (harvest) to delivery to consumers. In particular, in Korea, the insulation material used in the food cold chain is mostly EPS (Expanded Polystyrene), which is used as a transport container for various food cold chains. However, according to the government's eco-friendly policy, companies charge environmental contributions to the use of EPS, but due to its low price and convenience of handling, it is still used as a container for delivering food. In this study, in order to measure the domestic delivery environment of general refrigerated foods, changes in impact, temperature, and humidity during transport of the EPS packaging system containing foods and ice pack refrigerants were measured. As a result, there were 2?3 sections in which a high impact force of 40 G or more was generated during transport. This can cause damage to the product and EPS container. The difference in temperature and humidity changes by parcel transport routes is more than 30%, so it is necessary to present accurate standards for the domestic cold chain distribution environment. As a result of microbial experiments. the transportation period had a dominant effect on the increase in total viable count and E. coli count.

Recently, To define an enterprise's survival strategy is a difficult task, because the competition of a business is a complexity. The reason is the original research uses a statistical survey method. On a conceptual point of SCM, - as an order of development, physical distribution, logistics management, basic supply chain management and advanced supply chain management etc - a supervisor is magnifying gradually as well as confusing with information and analysis techniques which seems possible. On executing this, however, it has many problems since it is hard and wide; therefore, The Manager don't aware a total executable solution even though the enterprise knows necessity of SCM. On this paper focus on a proposal of alternatives with reasonableness of manufacturing and making a profit of sales department like most of enterprises are willing to overcome such as carelessness and unready strategy of investment additionally, the thesis should effort to find an element through an analysis of cases, a statistical method of effective SCM, and actual survey to propose an alternative; moreover, this paper proved the facts that it could be a guiding company, which has an ability of cooperation with entities through the founding of supply chain. As a conclusion, this essay showed the variation that influences the capacity entities and alternative to define an element which basically influence for a cause and effect.

In statistical process control applications, variable sample size (VSS) $\bar{X}$ chart is often used to detect the assignable cause quickly. However, it is usually assumed that only one assignable cause results in the out-of-control in the process. In this paper, we propose the algorithm to minimize the function of cost per unit time and compare the economic design and the statistical design by use of the value of cost per unit time. We consider double assignable causes to occur with compound in the process and adopt the Markov chain approach to investigate the statistical properties of VSS $\bar{X}$ chart. A procedure that can calculate the control chart's parameters is proposed by the economic design.
