This research investigates whether product types moderate the relationship between e-tailer characteristics and shopping attitudes in the context of online category killer stores. To identify the antecedents of consumer attitudes for category killer stores, the product types are characterized by the two dimensions of hedonic and utilitarian. A total of 268 responses were collected from consumers who experienced online category killer stores. The results show that the quality of information contained in a website, customer review, relational benefits, and the expertise of the e-tailer are important determinants for shopping attitudes of consumers. Regarding the moderating effects of product types, hedonic value significantly moderates the relationships between shopping attitudes and relational benefits/e-tailer expertise. However, utilitarian value does not significantly moderate the relationships between shopping attitudes and any of the e-tailer characteristics. Theoretical contributions of this study are the findings of moderating effects of hedonic value on the relationships between e-tailer characteristics and shopping attitudes. In addition, this study practically implies how companies can utilize these characteristics strategically for marketing and the selection of products.

The welding pressure in porthole die extrusion is affected by the shape of welding chamber. It is very important to increase the welding pressure when the tube is used particulary as the materials of hydroforming processing. The high circumferential stress of the tube would make the welding pressure increase during the porthole die extrusion. In order to increase the circumferential stress, it is necessary to make the billets pass through the narrow gap between the conical die and the conical mandrel. This paper describes the welding pressure by the experiments with the two types of the chamber. One of them is the chamber between the flat die and straight mandrel, and the other one is the chamber between the conical die and conical mandrel. The result of the experiments show that the conical chamber makes the welding pressure increase by the effect of the reducing the diameteres of tube.

IPsec is a standardization way for protection of IP packets in network layer and it is composed of three protocols that is AH(Authentication Header), ESP(Encapsulation Security Protocol) and IKE(Internet Key Exchange). Before doing encryption and decryption using AH or ESP protocols, both of communicating entities have to share same key safely. IKE protocol works automatically. But it has less interoperability because IKE protocol is not simple. A work which standardize IKEv2 has been done up to now. In this article, we will examine the Cryptographic Algorithms of IKEv2, and describe the AES usage with IPsec, based on the IETF Draft document.

The qualities of Deodeok Doenjang including physicochemical characteristics and sensory properties were investigated over the following range of Deodeok levels: 5, 10, 15 and 20% (all w/w). The strains used in the manufacturing of Doenjang were Bacillus sp. B-3 and Aspergillus sp. M-9 with the highest enzyme activities like amylase and protease. In case of Deodeok Doenjangs prepared with Bacillus sp. B-3, the amino-type nitrogen of Doenjang containing 10% (w/w) Deodeok was produced more than others during fermentation for 40 days. Amino-type nitrogen produced in Deodeok Doenjang prepared with Aspergillus sp. M-9 was more than one of Deodeok Doenjangs with Bacillus sp. B-3 and a commercial Doenjang. When Deodeok content exceeded 15% (w/w), higher content resulted in lesser amino-type nitrogen production. The results showed that Deodeok had influenced growth of Bacillus sp. and Aspergillus sp. Sensory evaluation showed that Deodeok Doenjangs containing 10% (w/w) Deodeok and 1% (w/w) Bacillus sp. B-3 and containing 20% (w/w) Deodeok and 1% (w/w) Aspergillus sp. M-9 were superior to the other Doenjangs tested.

Purpose - This study aims to examine the effect of audience attitude toward product placement, or PPL, on product attitude and purchase intention. PPL has increasingly been prevailing in TV dramas since the revision of the Broadcasting Act in January 2010, and it is quite widespread in today's society. Therefore, this study intends to investigate how the audience would take a particular attitude toward PPL in TV dramas and how their attitude would affect their product attitude and purchase intention. Research design, data, and methodology - The sample for the current study was drawn from college students in Seoul in December 2013, as the main targets of the products and brands that were advertised by PPL are young people. The questionnaire for this study comprised nine parts, such as the knowledge of PPL, experience of PPL, TV drama watching time, impulsive buying propensity, celebrity imitating buying propensity, attitude toward PPL, attitude toward product, purchase intention, and demographic characteristics. The questionnaire items were measured by 5-point Likert scales. Whether the demographic characteristics and propensity to consume would affect PPL attitude was analyzed and how the PPL attitude would affect purchase intention through product attitude was analyzed as well. To analyze the relationship between variables, structural equation modeling analysis was performed with Amos 18.0. Results - The major findings of the study were as follows. First, whether the demographic characteristics and propensity to consume would affect PPL attitude was analyzed, and it is found that out of the demographic characteristics, only gender and knowledge of PPL exerted an influence on PPL attitude. In addition, celebrity-imitating buying propensity had an impact on PPL attitude. Second, whether PPL attitude would affect purchase intention through product attitude was analyzed by structural equation modeling. Consequently, it is found that PPL attitude impacted purchase intention through product attitude. Conclusions - The findings of the study had the following implications. First, in theoretical aspects, previous studies have proven only that attitude toward PPL influenced attitude toward product and purchase intention separately; however, the current study has investigated the mediated role of attitudes toward PPL. Second, regarding the practical aspects, as PPL attitude exercised an effect on purchase intention as well as product attitude, PPL should be utilized in a manner to stimulate the audience to take a positive attitude to it. Finally, gender, PPL knowledge, and celebrity-imitating buying orientation were identified as influential factors for PPL attitude. Specifically, female consumers showed a lower attitude toward PPL than males, and the consumers who have no knowledge showed a lower attitude toward PPL. The consumers who have celebrity imitating buying propensity expressed a higher attitude toward PPL. These factors should consequently be taken into account when PPL is planned and conducted. The current study has limitations such as the sample object, non- experimental method, and media biases. Therefore, future research should be conducted to address these limitations.

Proposing a method for the estimation of the social cost for global warming impact (external cost) is the aim of this paper. Both the endpoint approach and conjoint analysis were applied to estimating the social cost for global warming. The endpoint approach was used to assess the damage on the safeguard subjects by global warming due to the emission of greenhouse gases into the atmosphere. The conjoint analysis was used to estimate the economic values for safeguard subjects which measure the social preferences and willingness to pay (WTP) on safeguard subjects. The economic values of human health and social asset were estimated at 62,261,700 Won / DALY (yr) and 10,000 Won / 10,000 Won, respectively. Moreover, cost factors of GHGs were calculated by multiplying the damage factor which is quantified the unit damage on safeguard subject and the economic value. In the case of CO$_2$, the cost factor was calculated at 13.52 Won / kg (13,520 Won / ton). External cost of products or services can be calculated by multiplying the GHG inventory result of products or services by the cost factor of each GHG. inventory.
