Purpose - Previous studies on the influence of appeal types of advertising messages on pro-social behavior have shown inconsistent results. The purpose of this study is to examine whether the appeal type of advertising affects consumer's prosocial behavior. In particular, the authors investigated whether the social exclusion moderates the relationship between the appeal type of advertising and prosocial behavior. Research design, data and Methodology - To verify the hypothesis, two experimental study were conducted. The experimental study was 2(appeal type : self-benefit vs. other-benefit) by 2(social exclusion : being ignored vs. being rejected) between-subject design. Participants were randomly assigned to one of four conditions. The experiment was conducted using a computer. First, the participants was exposed to the advertising image used in the social campaign, and then responded to questions about social behavior. The participants completed the experiment after further responding to the item for manipulation check and demographic measure. The experiment took about 10 minutes in total. Results - In Study 1, a global warming campaign with participation intention variable, other-benefit ads rather than self-benefit ads drive consumers who feel socially rejected to be more willing and likely to participate, but consumers who feel socially ignored are more likely to participate the campaign in self-benefit ad than other-benefit ad. Study 2 replicates the findings, a child poverty relief campaign with an amount-to-donate variable: consumers who feel explicitly rejected allocate more dollars to the charity in response to other-benefit rather than self-benefit ads, but consumers who being ignored are willing to donate more money. Conclusion - This study has theoretical contribution in that it expands existing theories by explaining the existing inconsistent results of the message appeal influence on pro-social behavior through new control variables. In addition, the results have important managerial implications, suggesting marketers should tailor their marketing message to match the consumer situation.

Coffee is one of the most popular drinks in the world. Roasting process of coffee bean is one of major steps to make coffee, however, there are few studies which analyzed chemical compounds in intermediate state of roasting coffee beans due to technical limitations to get coffee beans with the same roasting condition. We utilized Stronghold S7 pro roasting machine which guarantees the saming roasting conditions repletively with the aid of precise computer to control heat sources to get 20 steps (every 30 seconds) of roasted coffee beans during roasting process (10 min in total). Along with roasting process, phenolic compounds were decreased, which can be explained that roasting process cause phenolic compounds degradation. Caffeine is almost constant during roasting, reflecting that caffeine is not affected in roasting process. These samples presents that organic acids significantly increase along with the roasting process by HPLC analysis. With additional analysis of coffee beans, such as moisture contents, pH, as well as coffee tastes, our analysis will show detailed process of chemical compounds of coffee beans during roasting process.

This study examines whether cyberspace produced by computer mediated communication(CMC) would perform the public sphere through the agenda-setting process. By doing this, this study focused on how the cyberspace agenda is set and on how the characteristics of cyberspace and the mass media influence the cyberspace agenda-setting process. Through this study, the possibility of cyberspace as the public sphere is found although the characteristics of cyberspace decide this possibility. In particular, in order for cyberspace to contribute to enhancing democracy as a form of alternative media, the interaction among cyberspace, mass media and the off-line arena is a necessary condition. The interaction between cyberspace and mass media regarding the Sungsoo Women's Middle School violence case provides two very important points. First, cyberspace helps the individual agenda to be adopted by mass media as the media agenda. Second, mass media confirmed the credibility of cyberspace agenda through reporting. In addition, this study reveals that cyberspace would perform as the public sphere only when the interaction between on-line and off-line is provided.

This paper proposes to increase an efficiency of somebody searching information by a visualization of an unseen query words with well-selected user's intent structures. If a search engine identifies user's intent to pursue information, it would be an effective search engine. To do so, it is needed that relationships between query-words are to be visible after recovering words lost during formulated, and that an intention structure/elements is to be established. This paper will review previous studies, after then, define a simple structure of the search intent, and show a process to expand and to generate the query words appropriate to the intent structure with a method for the visualization of the query words. In this process, some examples and tests are necessary that one of the multiple intent structured layers is to assign to a range of query-words. Increasing/Decreasing an efficiency are analyzed to find. Future research is needed how to automate a process to extend structural nodules of user's intent.

It is necessary to measure cracks on concrete slab surface accurately in concrete structure maintenance for the stability of the structure. However, in real world, the process is done by time consuming and ineffective manual inspection. Although there have been some studies to provide computerized inspection methods, they are vulnerable to rugged surface or noise due to the influence of the light or environmental reasons. In this paper, we propose a new method that extracts not only undistorted cracks but minute cracks that were often regarded as noise. We extract candidate crack areas by applying fuzzy method with R, G, and B channel values of concrete slab structure. Then further refinement processes are performed with SOM algorithm and density based cutoff to remove noise. Experiment verifies that the proposed method is sufficiently useful in various crack images.

Spectra for the $v_3$+ Amide II combination band of thioacetamide(TA) were obtained in carbon tetrachloride solutions and in very dilute solutions of TA-N,N-dimethlylacetamide (DMA) in carbon tetrachloride in the range of 5~55$^{\circ}$C. The combination band in the three component system can be resolved into components due to monomeric TA, 1 : 1 TA-DMA complex and 1 : 2 TA-DMA complex. In the dilute solutions the experimental spectrum was resolved by using the computer into its two Lorentzian-Gaussian product components which have been identified with the monomeric TA and the 1 : 1 complex. The equilibrium constants and thermodynamic parameters of 1 : 1 complex were determined by analysis of concentration and temperature dependent spectra. The ${\Delta}H^{\circ}$ and ${\Delta}S^{\circ}$ for the 1 : 1 complex were -14.4 KJ mol$^{-1}$ and -15.6 J mol$^{-1}deg^{-1}$, respectively.

Near-ir spectra have been obtained for the $ν_3$+ Amide II combination thioacetamide(TA) band in CC$l_4$ and TA-DMP in CC$l_4$ in the range of 5 to 55${\circ}C$. Absorbance of the weak bands of the DMP and solvent has been compensated. The spectra are analyzed by the computer resolution into two Lorentzian-Gaussian product bands which have been identified with monomeric TA and 1 : 1 TA-DMP complex. Equilibrium constants and thermodynamic parameters for the hydrogen bonding between TA and DMP have been evaluated by the analysis of the concentration and temperature dependent spectra for the very dilute CC$l_4$ solutions. The $ΔH{\circ} and ΔS{\circ}$ of TA and DMT have been found to be -14.6 kJmo$l^{-1}$ and -16.2 Jmo$l^{-1}$ de$g^{-1}$.

More people travel oversea as the economic size of Korea is getting larger and more new jobs are requested to be created by the society. To respond to these trend and request, Incheon International Airport Corporation (IIAC) is about to expand its processing capability with a new terminal; 54 million passengers to 72 million. IIAC is also introducing new strategies such as open innovation (OI) and creating shared value (CSV). With these changes, IIAC faces new challenges of restructuring its business and organization with new ideas. Most organizations including IIAC are becoming more dependent on external resources to keep their competitive advantages under the turbulence of global business environmental changes. Therefore, they focus on the OI paradigm which is reported as a convincing strategy to improve competitiveness in terms of budget and time-to-market. OI is to quickly react to the rapidly changing business environment and is adopted to support startup incubation. In the previous research with IIAC, three major tasks were defined; utilizing the IIAC brand power for external vendors, building a technology road-map, and introducing a collaboration support system. This paper deals with the collaboration system as proposed in the previous research. We focused on the collaboration process for startup incubation. Cases were studied; the K-startup model by the government, a university model to explore youth startups, and a R&D institute model to study professional startups. Based on the case studies, we defined an IIAC model and proposed issues to take care of. The model is distinguished from the other studied models since IIAC is a prospective customer of new technology.

On a huge space of information called the Internet, users can use a smart mobile web to get information on various intellectual fields and can access to various Medias such as personal blogs and social networking sites (SNS). This is why a vast amount of information on the web has been effectively managed and researched nowadays through a technology named Semantic Web. However, it still needs for an improvement for studies on searching for intellectual information, though it is enhanced to integrate variously spread information and search for intellectual information user-oriented. Thus, this study aims to research on searching information and knowledge spread around a knowledge-filled information space, which can improve credibility according to user-oriented logic.
