With the rapid development of information technology, the ways of usage have changed drastically. The ways and efficiency of traditional service application to data processing already could not satisfy the requirements of modern users. Nowadays, users have already understood the importance of data. Therefore, the processing and saving of big data have become the main research of the Internet service company. In China, with the rise and explosion of 115 Cloud leads to other technology companies have began to join the battle of cloud services market. Although currently Chinese cloud services are still mainly dominated by cloud storage service, the series of service contents based on cloud storage service have been affirmed by users, and users willing to try these new ways of services. Thus, how to let users to keep using cloud services has become a topic that worth for exploring and researching. The academia often uses the TAM model with statistical analysis to analyze and check the attitude of users in using the system. However, the basic TAM model obviously already could not satisfy the increasing scale of system. Therefore, the appropriate expansion and adjustment to the TAM model (i. e. TAM2 or TAM3) are very necessary. This study has used the status of Chinese internet users and the related researches in other areas in order to expand and improve the TAM model by adding the brand influence, hardware environment and external environments to fulfill the purpose of this study. Based on the research model, the questionnaires were developed and online survey was conducted targeting the cloud services users of four Chinese main cities. Data were obtained from 210 respondents were used for analysis to validate the research model. The analysis results show that the external factors which are service contents, and brand influence have a positive influence to perceived usefulness and perceived ease of use. However, the external factor hardware environment only has a positive influence to the factor of perceived ease of use. Furthermore, the perceived security factor that is influenced by brand influence has a positive influence persistent intention to use. Persistent intention to use also was influenced by the perceived usefulness and persistent intention to use was influenced by the perceived ease of use. Finally, this research analyzed external variables' attributes using other perspective and tried to explain the attributes. It presents Chinese cloud service users are more interested in fundamental cloud services than extended services. In private cloud services, both of increased user size and cooperation among companies are important in the study. This study presents useful opinions for the purpose of strengthening attitude for private cloud service users can use this service persistently. Overall, it can be summarized by considering the all three external factors could make Chinese users keep using the personal could services. In addition, the results of this study can provide strong references to technology companies including cloud service provider, internet service provider, and smart phone service provider which are main clients are Chinese users.

This study is conducted to prove a hypothesis that Dokdo Island has "National Landscape Image," being a region with special meaning for Korean people. University students(51 Koreans and 44 foreigners) were surveyed on landscape images of Dokdo Island, and the statistical analysis of the survey responses was performed subsequently. The findings showed no substantial difference between the opinions of Korean men and women: Especially the photo of whole Dokdo was highly rated by Korean respondents as "considerably or very valuable and impressive, but also mysterious and symbolic at the same time." These are unique images of Dokdo Island, which are not found in responses to natural landscape of other national parks. Meanwhile, there were significant contrasts between the responses of Koreans and foreigners in every variables. Some landscape adjectives used as semantic differential scale demonstrate remarkable differences between Korean and foreign respondents, particularly on the photo of whole Dokdo: impressive(1.41), mysterious(1.25), symbolic (1.00), valuable(0.98), intimate(0.95), beautiful(0.93), interesting(0.85). There were substantial differences in responses between Korean and foreigners on two rock islands, which have names related with some national image: The Korean Peninsula Rock(0.57) and Independence Gate Rock(0.51). Finally, three primary factors drawn from the factor analysis were (1) national landscape image, (2) natural characteristics of Dokdo Island, and (3) spatiality of Dokdo Island.

Public concern about potential environmental risks of agricultural business for the livestock production and processing is increasing. However, due to differences in general industry structural characteristics, such as farm production and waste management practices, the effect of environmental policies may differ from species to species as well as across size categories. I hypothesize that additionally the Hog subsector may be more responsive to (or a greater driver of) a changing environmental policy environment than the beef cattle subsector. As a result, I expect to see more evidence of sensitivity in the environmental policy milieu from hog-operation stocking and location decisions than with the beef cattle industry. The written stringency may not effective, instead state's willingness to enforce has directed and regulated. However, in presence of rapid structural change, just like hog, industry location is affected by state regulation. The environmental compliance cost may be a small portion of industry total cost and fixed cost of beef industry makes for them to take into account environmental compliance for their decision location making. The special movements of flog industry have chance to minimize the cost of the operation and they willing to locate less stringent place.

Since the 1990s rising intangible asset has become one of the main driving forces of investment stagnation and jobless growth in advanced income countries. We investigate how does the impact of firms' profitability on employment growth depends on the intangibility and whether the relationship between profitability and tangibility has complementarity. With data on Korean firms over the period 1988~2017 we investigate the effects of intangibility and profitability on employment growth based on the econometric approach of system GMM. The empirical results are as follows. (1) the profit rate has gradually led to lower employment growth, while it had positive effect on employment before the period of financial crisis. The estimated values and signs of profit rate coefficients varies from traditional industries to high/medium tech. industries. (2) the effect of increasing asset intangibility ratio on employment growth is negative and statistically significant. (3) the coefficients of interaction term of (profit rate ${\times}$ intangibility ratio) have significant negative values. It means employment effect of profit rate are becoming higher(lower) as intangibility ratio is at the lower(higher) level; profits rate and intangibility are not complement with each other. The results imply that to boost employment industrial policy which has the capacity to coordinate business intangibility is preferred to expansionary demand policy.

Platform is considered as an alternative strategy to the traditional linear pipeline based business. Moreover, in the 4th industrial revolution period, efficiency driven pipeline business model needs to be changed to platform business. We have such success stories about platform as Apple, Google, Amazon, Uber, and so on. However, for those smaller corporations, it is not easy to find out the transformation strategy. The essence of platform business is to leverage network effect in management. Thus platform based management can be rephrased as network management across the business functions. Research on platform business is popular and related to diverse facets. But few scholars cover what the research trend of the domain is. The main purpose of this paper is to identify the research trend on platform business in Korea. To do that we first propose the analytical model for platform architecture whose components are consumers, suppliers, artifacts, and IT platform system. We conjecture that mapping of the research work on platform to the components of the model will make us understand the hidden domain of platform research. We propose three hypotheses regarding the characteristics of research and one proposition for the transitional path from pipeline to platform business model. The mapping is based on the research articles filtered from the Korea Citation Index, using keyword search. Research papers are searched through the keywords provided by authors using the word of "platform". The filtered articles are summarized in terms of the attributes such as major component of platform considered, platform type, main purpose of the research, and research method. Using the filtered data, we test the hypotheses in exploratory ways. The contribution of our research is as follows: First, based on the findings, scholars can find the areas of research on the domain: areas where research has been matured and territory where future research is actively sought. Second, the proposition provided can give business practitioners the guideline for changing their strategy from pipeline to platform oriented. This research needs to be considered as exploratory not inferential since subjective judgments are involved in data collection, classification, and interpretation of research articles.

When assessing environmental or other regulatory programs, economists and other policy analysts have traditionally used the approach that consists of comparing the benefits from regulation with the costs that must be borne to capture these benefits. The vast majority of economic analysis of regulation was based upon the assumption that regulations increase production costs. Porter had disputed this seemingly straightforward claim. In his view, economists had failed to incorporate the capacity of stringent regulations to induce innovation into their analysis. However, at the same time, the hypothesis had been criticized by economists. This study analyzed the determinants of innovation performances as well as activities of small and medium manufacturers, based on a recently held survey among mainly manufacturing SMEs in Korea. In particular, this study took the level of innovation activities, the strength of environmental regulations, and moreover the impediment that the company went through as factors. In addition, the characteristics of innovative SMEs were compared with the other counterparts. The empirical analysis revealed that the level of environmental awareness, existence of innovative activities, characteristics of firms, and moreover the innovation types are the most important determinants of SMEs’ innovation performance both in technology as well as in economic perspective.

The purpose of this study is to examine the mobile phone service usage patterns of Korean teenagers and their motivation to use it, and to explore the relationships between the teenagers' social-psychological characteristics and their trails of mobile phone usage. After reviewing prior theoretical studios, three hypotheses regarding the research questions shown above were generated. Questionnaire study was conducted with 400 high school students in Busan and Ulsan metropolitan areas. They were to answer three categories of questions, such as frequencies of voice calls and text messaging services and the other mobile services, questions asking their social-psychological characteristics, and their motivations for using mobile phone services. Findings show that the teenagers more likely to tend to use voice calls when communicating family members. They tend to avoid those services with high rate of use as multimedia, game, and broadcasting services via mobile phones. The teenagers use mobile phone services for the similar purposes to conventional telephone uses. Therefore, the classical theories showing the alternative purposes or motivations to use conventional telephone usage, which divided the main purposes for phone uses in to two; work/instrumental and socializing/entertaining, proved to be reasonable. The cheap messaging services with texts are popular among the teenagers and are used for socializing/entertaining purposes rather than instrumental/functional purposes. In addition, the teenagers' social-psychological characteristicss are significantly associated with the amount of mobile phone uses. A characteristic of "individual-centeredness" is positively related with non-voice service uses, while "group-centeredness" explains heavy amount of using voice calls and text messaging services. Such characteristics as "immediacy," "directness," "innovativeness," and "other-direction" are positively associated with the frequencies and amounts of mobile phone uses, while "inner-direction" and "tradition-direction" are negatively correlated.

Lime-soil consolidations are very important as structural material, bonding material, waterproofing material, and finishing material in korea traditional buildings. In this study, we investigated site application trouble in korea traditional buildings being repaired or restored, and propose following solutions. 1) To diminish quality variation occurred by slaking quick-lime in site, it is desirable to use slaked-lime for lime-soil consolidation. 2) For uniform construction of lime-soil consolidation, we would recommend builders to use mixer to be uniform mixture, premixed type materials and compacting machine in field, 3) and to use rigid suitable temporary construction as scaffold for preventing traditional buildings from additional damage occurred in demolition and construction of a layer of lime-soil consolidation of a roofing. 4) For suitable repair of traditional buildings, it is necessary to specify definitely materials and construction methods suggested by the standard specifications for repair of the cultural property.

Into the telecommunications industry, which had been monopolistic, a few advanced countries introduced competition through 70's and 80's. And this trend is going on worldwide. The introduction of competition into the industry is made mainly in the long distance, international and enhanced market. This liberalisation results from the fundamental change of the cost function. Suggesting that the cost comprises of that of the facility sector and that of the operation sector there exists the economies of scale in the facility sector in general. The major ground for the monopolistic industrial structure in the past was the natural monopoly depending on the economies of scale. But the rapid advance of the technology by a large margin. This decrease has resulted in the change of the cost function. That is while there exists the economies of scale in the smaller production scale, the average cost increases beyond a certain scale. This means that the natural monopoly collapsed, and that the competitive structure is more efficient than the monopolistic structure. But, because there exists economies of scale in the smaller scale, the desirable number of players, which could result in efficient industry structure depends on the market size. Such correlation between technological level market size and the degree of regulation is found in the case of U.S.A., Japan and U.K., where deregulation policy of the telecommunications market has already been carried out. In U.S.A., which has the largest market and the highest technological level the degree of regulation is lowest. Also in the order of Japan and U.K. the regulation is severer. Japan and U.K. are likely to liberalize still more, as the technology advances and the market grows. This article is just the beginning of the research, and this hypothesis requires more detailed research.

Family, Self or State as a Desired Source of Support for the Elderly As Korean society has undergone rapid socioeconomic transformation and reached the final stage of its demographic transition, the central emphasis of population policies in Korea has shifted from fertility and population control to aging issues. Recently, it has been advocated that the Korean government should provide more intensive public services to supplement self-care and family caregiving, heightening the need to know more about the norms and expectations of old-age support and how they will change. Using the Survey of the Living Status of the Korean Elderly in 1994, this study investigates the extent to which the Korean elderly themselves view family, self, or the state as desired sources of support. The multinomial log it model analysis reveals that the elderly without a son are less likely to emphasize the traditional view of family, while economically and physically better off elderly are more likely to favor the view of self-support. However, the idea that the emphasis on the 'state responsibility' may be found among those elderly who are in need of financial help and in poor health is not supported. The implications and suggestions for further research are discussed.
