Cloud computing is getting a lot of attention by many people and businesses due to IT environmental changes such as the proliferation of smart devices, the increase of digital data, and the cost of IT resources. More individuals use personal cloud computing services for storing and managing information and data. Therefore, this study proposed determinants that are expected to have an influence on evaluating the value of cloud computing based on the value-based adoption model, examining the relationship between the continuous use intention of cloud computing. Results of the study show that usefulness, convenience of information access, extensibility had a positive impact on perceived value while privacy concerns and costs had a negative impact on perceived value. In addition, perceived value was found to have a significant effect on the intention to continue use of cloud computing. Finally, trust was found to have a significant effect on the perceived value and the intention to continue use of cloud computing. The findings are expected to provide useful information for understanding the factors that individual users consider important in the steadily growing cloud computing market.

In this study, a model to calculate the expected total construction cost is developed that simultaneously considers the rehabilitation cost related to the sliding of the caisson, the economic damage cost due to harbor shutdown in the event of excessive caisson sliding, and the economic damage cost due to temporal operational stoppage by excessive wave overtopping. A discount rate is used to convert the damage costs occurred at different times to the present value. The optimal cross-section of a caisson is defined as the cross-section that requires a minimum expected total construction cost within the allowable limit for the expected sliding distance of the caisson during the lifetime of the breakwater. Two values are used for the allowable limit: 0.3 and 0.1 m. It was found that the economic damage cost due to harbor shutdown by excessive caisson sliding is more critical than the rehabilitation cost of the caisson or the economic damage cost by excessive wave overtopping in the decision of the optimal cross-section. In addition, the optimal cross-section of the caisson was shown to be determined by the allowable limit for the expected sliding distance rather than the minimum expected total construction cost as a larger value is used for the threshold sliding distance of the caisson for harbor shutdown.

This study attempts to explore the connectivity among brand personality, shopping value, customer satisfaction and recommendation intention by deriving brand personality image factors of online shopping malls. The analysis results are as follows. First, the brand personality of shopping malls were derived as 'vital', 'familiar', 'credible', 'competent', and 'sophisticated.' Second, shopping value was derived as hedonistic and practical shopping values. Third, it was shown that brand personality of shopping malls has significant impacts on shopping value. In addition, customers' shopping value, customer satisfaction and recommendation intention have significant impacts on each other. It is expected that this study can provide basic information for constructing differentiated marketing strategies in the domestic online shopping malls whose competition is heating up.

The purpose of this paper is to estimate the economic value of Multi-functionality Roles including landscape and so on, which traditional stone fences in Korea possess, using Dichotomous Choice Contingent Valuation Method (DC-CVM). The stone fences is life cultural heritance of regional residents. It has functions like Development of Favorable Landscapes, Maintenance of Cultural Heritage, and Recreation/Relaxation. Expectation from regional visitors shows that the existence and inheritance value of the stone wall is higher then we expected. According to the research that we had done from the people that had agreed to contribute the stone wall. moreover the public commercial value of regional tradition stone was not only 2,900 billion won but also it will increase an economic gain in every year. Therefore, preserving the stone wall that has Multi-functional Roles and values can lead to huge economic value in the future. But farmhouses in the stone wall conservation area are being supported 9 billion won in every year. This is only 0.03% of the income that farmhouse earns per year. Thus, stone wall preservation policy and plan can raise green-tour commercial value of inland area as a long-term inside measurement. Those will have to be propelled continuously.

The purpose of this paper is to estimate the economic value of Multi-functionality Roles including landscape and so on, which the stone fences in Jejudo possess, using Dichotomous Choice Contingent Valuation Method(DC-CVM). The stone wall is life cultural heritance of Cheju islanders. It has functions like Development of Favorable Landscapes, Maintenance of Cultural Heritage, and Recreation/Relaxation. Expectation from Cheju visitors shows that the existence and inheritance value of the stone wall is higher then we expected. According to the research that we had done from the people that had agreed to contribute the stone wall, the result was that the public commercial value of Cheju tradition stone will increase every yew(2006: 367 billion won, 2011: 437.1 billion won). Therefore, preserving the stone wall that has Multi-functional Roles and values can lead to huge economic value in the future. But farmhouses in the stone wall conservation area are being supported 6 million won every year. This is only 10% of the income that farmhouse ems per year. Thus, stone wall preservation policy and plan that can raise green-tour commercial value of Cheju Island of long-term inside measurement will have to be propelled continuously.

This study was performed for parentage verification of the Korean native horse (KNH). 103 random KNH samples (including 19 foals for parentage testing) were genotyped by using 16 microsatellite markers. The number of alleles per locus varied from 5 to 13 with an average value of 8.56 in the KNH. The observed heterozygosity and the expected heterozygosity ranged 0.398-0.893 (the average value was 0.683) and 0.368-0.871 (the average value was 0.727) in the KNH, respectively. The PIC value and the exclusion probability ranged 0.347-0.853 (the average value was 0.692) and 0.208-0.736, respectively, and the total exclusion probability of 16 microsatellite loci was 0.9999. Of the 16 markers, AHT4, AHT5, ASB2, ASB17, HMS2, HMS3, HTG10, LEX33, TKY321 and VHL20 loci have a relatively high PIC value (>0.7) in the KNH. Of the 19 foals, 5 foals were disqualified by an incompatibility of 4-7 markers according to a Mendelian fashion in the present DNA typing for parentage testing. These results present basic information for developing a system for parentage verification and individual identification in the KNH.

The purpose of this study was to measure the effects of restaurant service quality dimensions on service value, satisfaction, and behavior intention. A total of 273 questionnaires were completed. A structural equation model was used to measure the causal effects. The results of the study show that the confirmatory factor analysis model presented an excellent model fit. The unrestricted model yielded a significantly better fit to the data than the two restricted models. In the unrestricted model, the effect of reliability on service value was statistically significant. The effects of tangibles and empathy on satisfaction were also statistically significant. As expected, empathy had a significant effect on behavior intention. Moreover, empathy had a significant indirect effect on behavior intention through service value and satisfaction. Restaurants should devote themselves to factors such as reliability in order to improve service value. Also, attention must be given to another important factor, empathy, since this influenced not only satisfaction, but also behavior intention.

Change requests occur persistently in the construction phase of a construction project. The law requires that the contract amount be adjusted in accordance with the relevant regulations when there is a change in the construction amount due to the design change in the construction contract. SAVE international, on the other hand, defines the value methodology as a systematic and structured approach to improving projects, products and processes. Design Changes in the construction projects require organizational efforts to improve value and quality. However, the law does not include change requests in which the VE object is fixed and related data is collected and function analysis can be derived in a short time. Therefore, it is necessary to apply VE to the design change procedure, which can further improve the value of construction work. The application derived from this study need to be presented as simply as possible without compromising the basic concept of VE. If the application is extended to the field and proved to be effective, it is expected to contribute to the overall value of construction work.
