Examination of the various impact factors on adoption sustainable IT can influence on the potential for creating sustainable businesses in today's society. However, the societal factor out of environmental factors, which stimulates customer intention to use sustainable IT, has seldom been investigated. In this paper, we examine the adoption of sustainable web technology from the pro-social behavior perspective. The concept of sustainable IT is theoretically examined based on social exchange theory. An empirical investigation is conducted into customer intention to use new sustainable IT. The results indicate that customers care about the social responsibility and usefulness of the sustainable IT-based services they choose. In this study, the social features of web technology and their influences on adoption are verified empirically for the first time. In addition, pro-sociality is identified as necessary to a perception of the socially responsible features of information technology. Furthermore, pro-social adoption behavior in the beginning stages of sustainable IT use is elucidated.

This study empirically examined the relationships among ethical leadership, supervisor identification(SI), affective commitment(AC), and unethical pro-supervisor behavior(UPSB) based on social learning theory and social exchange theory. The data were collected by conducting a survey of 339 workers and analyzed using SPSS25 and SPSS Process Macro (v3.5). The results were as follows. First, ethical leadership directly negatively influences UPSB. Ethical leadership indirectly positively influences UPSB mediated by SI. Second, ethical leadership, completely mediated by AC, indirectly positively influences UPSB. Third, ethical leadership has an indirect positive effect on AC mediated by SI. This study showed how ethical leadership works in organizations through social learning theory and social exchange theory. Also, it suggested implications on how to use ethical leadership in field.

Based on the previous analysis by Wanghongjun(2008), this paper applies Optimality Theory (OT) to the field of partial reduplication in Korea to increase its scientific validity. Toward this end, I propose an alternative analysis of Korean partial reduplication, applied as a single process of prefixation. Reduplicated words by prefixation are divided into two types: with a heavy syllable of the stem, and another with the stem. The two types of partial reduplication are closely related by the sound features. In addition, I discussed Chinese partial reduplication from a prefixation perspective within the framework of OT and performed contrastive analysis of Korean and Standard Chinese processes of reduplication by focusing on constrained rankings. As a result, the alternative analysis showed a systematic relationship among the reduplicated words in Korean and Standard Chinese. Lastly, I explained that the coronal /t/ and liquid /l/ have a special functional hierarchy in both languages. This study can be re-explained based on the framework of OT according to a few major constraints, involving MAX-BR, MAX-IO. Their rankings show the adequacy of analysis.

Purpose: The consolidation settlement of soft ground is dependent on the distribution of pore water pressure which is also affected by hydraulic conductivities (boundary condition) of layers, thickness of clayey soil layer and surcharge. Results: However, the current consolidation analyses are mostly based on Terzaghi's consolidation theory that assumes the initial pore water pressure ratio with depth to be constant. In this study, numerical analysis are carried out to investigate the variation of pore water pressure dissipation with depth and thickness of clayey soil layer, time, surcharge as well as drainage conditions. Conclusion: Comparative study with Terzaghi's consolidation theory is also conducted. The result shows that Terzaghi's consolidation theory should be used with caution unless it is ideally corresponded to the isochrone.

NFT art is a new art formed based on NFT technology. This is attracting great attention in the existing art world and art market. Therefore, it is required to analyze whether NFT art can establish itself as a new area of art. Therefore, the formation and development process of NFT art is analyzed from the perspective of Actor-Network Theory of Science and Technology and Studies, and the case of NFT artist 'beeple' is a representative example. It also discusses the artistic value of NFT art and its relationship with traditional art networks based on the aesthetics of science and technology researcher Graham Harman. In particular, it analyzes the future and genre sustainability of NFT art through the case of NFT project "Cryptopunks" and "PUNKISM" advocating a new art genre. By analyzing NFT art with ANT, I would like to raise a technical, aesthetic, and philosophical questions and propose a positive prospect as a new art genre.

In this study, the consolidation behavior of clayey ground improved by vertical drain method was analyzed by the finite difference method based on the three-dimensional elasto-viscous consolidation theory, which can express the behavior of the secondary consolidation without considering the distinction of the normally consolidated and overconsolidated states. And the applicability of the elasto-viscous consolidation theory was discussed by comparing with the test results obtained from the model test of ground improved by vertical drain system. From these results, it is found that the amount of the settlement when the excess pore water pressure almost dissipated in the clay ground with vertical drains became smaller than that of the one-dimensional condition, and then the amount and rate of the residual settlement at secondary consolidation process became larger than those of the one-dimensional condition. finally, the effect of soil parameter on behavior of consolidation process was investigated by the results of a series of numerical analysis for the normalized and overconsoldiated states.

In order to estimate undrained shear strength and evaluate cone factors, various in-situ and laboratory test results at new harbor construction area near Pusan were analyzed. To evaluate Nk values and equation applicable in Korea, measured and theoretical cone factors were compared based on the test results. For comparison, various analytical solutions were adopted and used. Adopted methods include cavity expansion solutions of Baligh (1975) and Yu (1993) and steady state solutions of Teh and Houlsby (1991) and Yu et al. (2000). According to the result of comparison, cavity expansion solutions were found to be reasonable for the CPTu-based undrained shear strength evaluation.

This study seeks to understand the effects of information search activities and brand image on the hotel patronage intention based on the theory of reasoned action. First, it investigates the influence of attitude formed about hotel on the patronage intention. Second, it seeks to develope an alternative to TRA by looking into the effects of hotel image variable on hotel-specific attitude and patronage intention and attempts to substantiate the role of brand image as a substitute to subjective norm to increase the TRA's explanatory power. The main finding of this study are as follow; First, out of the three components of cognitive evaluation of hotel (human service, physical service and information service), human and physicial services were found to have significant influence on patronage intention. Brand image was found to exert notable influence on attitude toward hotel as well as patronage intention. Remarkably, the finding that brand image positively enhanced the TRA model sheds new strategic insight as to the usefulness of brand image as an alternative to overcome the TRA's limitation stemming from subjective norm. Third, it was learned that study subjects gave more weight to external information sources such as TV, radio, newspaper, magazine, and internet than to internal sources such as individual knowledge, experience or self image.

Korean peninsula has a long history and a geopolitical location as a buffer tone, which has provided the conditions for cultural dynamism and diversity across space and time. The changing processes of place names in Korea is considered to be better suited to the study on cultural politics that is interested in the culture wars over the meaning of culture among different social subjects. In order to ensure the legitimacy of cultural politics for the study of place names in Korea, this study attempts to make a theoretical construction based on the concepts of place identity, territorial contestation, and the politics of scale. Cultural and linguistic theories to be best applied to the study of place names in Korea are the theories on Angehm's and Castells' identity, $P{\hat{e}}cheux's$ identification, Hall's decoding, and Voloshinov's ideological sign. Power relations involved in the inclusion and exclusion are necessarily concerned with the process of constructing a place identity or territorial identity by means of a place name, which represents identity and ideology of a social subject. In the examination of this process, it is necessary to take the elements of identity, ideology and power relations into consideration. In this study, therefore, the politics of scale is experimented for its applicability in the study of place name in Korea, which is expected to accommodate concepts of boundary, territory, territoriality and territorialization. In the end, it is suggested in this study that a series of basic and interdisciplinary studies on the cultural politics of place names in a range of area should be undertaken along with the enough theoretical knowledge of cultural politics.

In general, conventional road pavements are designed under the assumption that the shear strength of geomaterials are under saturated state. In reality, however, most of the pavement geomaterials exists under the unsaturated state. To deal with this gap between saturated and unsaturated conditions, in this paper, unsaturated shear strength was estimated using the results from the triaxial compression test and soil-water characteristics curves. Then, yield loads were assessed using 2-Dimensional finite element method with the selected nonlinear elastic model and the Mohr-Coulomb yield criteria. In addition, various unsaturated condition and surface layer effects on the yield load of granular materials were identified. Therefore, the results demonstrated would provide a possibility to estimate bearing capacity of paved or unpaved roads using unsaturated soil mechanics.
