The exponential growth of the on-line shopping mall has been the advent of buying and selling products and services over the internet. In these circumstances, this paper presents the importance of understanding and managing the purchasing behavior of on-line shopping mall customers. The main purpose of this research is to find out the antecedents of customer trust and to conceptualize and investigate the relationship between endogenous mediating variables(such as customer trust, attitude, loyalty, relationship involvement) and purchasing and/or repurchasing intention in internet shopping mall. The empirical findings are as follows : First, the three antecedents of customer trust( EC system characteristics, psychological propensity, and trustworthiness) had the positive effects on the formation of site trust. Second, we found out that there were direct or indirect relationships between the mediating variables and on-line purchasing and/or repurchasing intention. In Particular, the direct effects of customer attitude on customer loyalty and buying intention were rejected, but the indirect effects through relationship involvement were accepted. This means that the relationship marketing is probably more important for the success of internet shopping mall Third, there were no direct relationship between the mediating variables and the repurchasing intention, but most researches in the brick and mortar, the proposition are supported. This implies that repurchasing intention was intensified by the indirect path, such as site trust $\longrightarroe$ attitude $\longrightarroe$ involvement $\longrightarroe$ loyalty $\longrightarroe$ purchasing intention $\longrightarroe$ repurchasing intention. So, the internet marketers must make an effort not only to strengthen the direct casual linkage between them but also to consolidate the indirect connections leading to boost purchasing and repurchasing intention.

In this paper, we analyze the conditions of generating the dynamic Web documents in multi-user server and propose effective method for it. PSSI technique leads to replace the complex process of modifying a CGI source program by simply correcting the HTML Web document in the external file form. This technique has the strong points of CGI, flexibility and security of programming as well as those of SSI, easiness of modifying Web documents. Due to the characteristics of PSSI that Web source documents are in the form of external file, we show that with a single CGI program an individual user can design and modify his own Web documents in his directory. This means that PSSI technique has more advantage in managing the server than the CGI method which requires CGI program to be set up whenever that service is needed.

The current user interface (UI) of NEIS school affairs business system is not efficient in conducting the business because of complicated data input forms as well as unharmonious connection between similar items and functional menu. In the paper, the term UI means a comprehensive concept including input/output, input/output related functionality, and menu configuration for users to perform their tasks. The first survey, carried out with one hundred teachers at three elementary schools of Kyeonggi-do, shows that the UI problems of the system are manual inputs, inconvenient menu configuration, disconnection between academic calendar and educational process, complexities of managing attendance report and curriculum evaluation, etc. We have improved the UI design by providing more efficient input method and more systematic menu configuration compared to the current system, and then evaluated the design through the second survey. Evaluation results show that users prefer the proposed UI design especially from the viewpoint of user-friendly input interface and user-oriented view composition.

Chosen General Government initiated the activities of collecting and managing the archives from Chosen Dynasty because of necessity to push positively for its colonial policies. Particularly, such efforts of the regime resulted eventually in boosting their understanding on the Korea cultures, as well as contributed to their reigning Korea to an extent. Some aspects that reflect it are as follows. In 1910 Chosen General Government took over, and began to arrange and classify huge volumes of archives that were held by the royal family. During this period, they collected and arranged literatures that they took over from the earlier Korean government. In 1913, Chosen General Government increased enormously the varieties and volumes of the archives that they intended to collect. They started with collecting archives limited to those literatures that had existed in the civil sector before 1894. It can be noticed that just in 1913 Chosen General Government revealed their intention to collect and classify both royal archives and civil archives. With the work of collecting, classification and annotating archives, Chosen General Government commenced the compilation of Chosensa (Korean History). These efforts aimed at cultural assimilation and educating of Korean people, and in this process, the importance of Chosen Dynasty's archives was reconfirmed. One of the representative cases was a change of terminology. With the compilation efforts into full swing since 1915, Chosen General Government repeatedly started to use the term 'Saryo' (historical records) in connection with Chosen's literatures and archives. The term 'Saryo' previously had been used in Japanese literatures, and it is deemed that it was used as a term generally referring to archives of Chosen Dynasty from that time. This signifies that Chosen General Government began to involve their historical point of view in approaching to the archives of Chosen. As they broadened their understanding on Korea through the annotation of old literatures and compilation of Chosen History, they seriously set on the work of assimilating Korean people culturally aiming at gripping its reign on Korea. Archives of Chosen likewise were very crucial basic data for understanding Korea and its people, and Chosen General Government is deemed to have utilized the archives as a means to reign and assimilate Korean people.

In genaral appraisal is process of the determining the length of the time records should be retained, and is defined as selecting records with second value. However, appraisal in boroad term includes analysis which value records have as well as selecting archival records. It means that analysis of Records value is carried and reflected in every processes of maintenance, use and disposition of records. One of characteristic in records and archives management is that records process doesn't finish as one process, but it creates and manages records repeatedly. When another records are created again after the previous process in these system, it should creates records with better value than before. It pursues positive circle system which satisfy users whenever it starts. The study reviewed how analysis of records value is reflected in Records and archival system in Korea, and analysed Public Records and Archives Act to approve it. In results the study suggests having positive circle system finally.

This study aims to conduct a depth analysis of motivation and value of local residents and tourists based on means-end chain theory. The sampling of the study was conducted on local residents living near downtown area of Gyeong-ju City, and tourists through soft laddering and hard laddering methods. A mutual correlation model in relation with Hierarchical Value Map (HVM) for each group by conducting the analysis of factor loading (attributes, consequences, value) and cognitive structure (the correlations among attributes, consequences and value) was proposed and the comparisons of HVM for each group was also conducted. The structured questionnaires using Association Pattern Technique (APT) of hard laddering were utilized to analyze the means and end of value chain structures in terms of the attributes, consequences, value of Gyeong-ju Ancient Tombs. The findings propose that local residents are visiting Ancient Tombs Gyeong-ju City Center for 'Rest and take a walk' as the means, which results in 'Relieving stress' and eventually leads to the 'Improvement of historic and cultural cultivation' as the end. On the other hand, tourists also 'Rest and take a walk' as the mean, which also leads to 'Relieving stress'. However, unlike local residents, it eventually leads to 'Self-reflection and healing' as the end. It is expected that the findings of this study not only recommend us to consider preserving and managing cultural heritages and value of ancient tombs in developing "Ancient Tomb Park in Gyoneg-ju City Center" but also provides baseline data for the establishment of reasonable plans of utilizing tombs, historical and cultural heritages.

The purpose of this research is to develop a detection model for companies designated as administrative issue in KOSDAQ market using financial data. Administration issue designates the companies with high potential for delisting, which gives them time to overcome the reasons for the delisting under certain restrictions of the Korean stock market. It acts as an alarm to inform investors and market participants of which companies are likely to be delisted and warns them to make safe investments. Despite this importance, there are relatively few studies on administration issues prediction model in comparison with the lots of studies on bankruptcy prediction model. Therefore, this study develops and verifies the detection model of the companies designated as administrative issue using financial data of KOSDAQ companies. In this study, logistic regression and decision tree are proposed as the data mining models for detecting administrative issues. According to the results of the analysis, the logistic regression model predicted the companies designated as administrative issue using three variables - ROE(Earnings before tax), Cash flows/Shareholder's equity, and Asset turnover ratio, and its overall accuracy was 86% for the validation dataset. The decision tree (Classification and Regression Trees, CART) model applied the classification rules using Cash flows/Total assets and ROA(Net income), and the overall accuracy reached 87%. Implications of the financial indictors selected in our logistic regression and decision tree models are as follows. First, ROE(Earnings before tax) in the logistic detection model shows the profit and loss of the business segment that will continue without including the revenue and expenses of the discontinued business. Therefore, the weakening of the variable means that the competitiveness of the core business is weakened. If a large part of the profits is generated from one-off profit, it is very likely that the deterioration of business management is further intensified. As the ROE of a KOSDAQ company decreases significantly, it is highly likely that the company can be delisted. Second, cash flows to shareholder's equity represents that the firm's ability to generate cash flow under the condition that the financial condition of the subsidiary company is excluded. In other words, the weakening of the management capacity of the parent company, excluding the subsidiary's competence, can be a main reason for the increase of the possibility of administrative issue designation. Third, low asset turnover ratio means that current assets and non-current assets are ineffectively used by corporation, or that asset investment by corporation is excessive. If the asset turnover ratio of a KOSDAQ-listed company decreases, it is necessary to examine in detail corporate activities from various perspectives such as weakening sales or increasing or decreasing inventories of company. Cash flow / total assets, a variable selected by the decision tree detection model, is a key indicator of the company's cash condition and its ability to generate cash from operating activities. Cash flow indicates whether a firm can perform its main activities(maintaining its operating ability, repaying debts, paying dividends and making new investments) without relying on external financial resources. Therefore, if the index of the variable is negative(-), it indicates the possibility that a company has serious problems in business activities. If the cash flow from operating activities of a specific company is smaller than the net profit, it means that the net profit has not been cashed, indicating that there is a serious problem in managing the trade receivables and inventory assets of the company. Therefore, it can be understood that as the cash flows / total assets decrease, the probability of administrative issue designation and the probability of delisting are increased. In summary, the logistic regression-based detection model in this study was found to be affected by the company's financial activities including ROE(Earnings before tax). However, decision tree-based detection model predicts the designation based on the cash flows of the company.

In present, the Seoul City is undergoing traffic congestion problems caused by rapid urbanization and population growth. Thus the City government has reorganized the mass transportation system since 2004 and the subway has become a very important means for public transit. Since the subway system is typically a closed environment, the indoor air quality issues have often raised by the public. Especially since a huge amount of PM (particulate matter) is emitted from ground tunnels passing through the subway train, it is now necessary to assess the characteristics and behaviors of fine PM inside the tunnel. In this study, the concentration patterns of $PM_1$, $PM_{2.5}$, and $PM_{10}$ in the Seoul subway line-2 were analyzed by real-time measurement during winter (Jan 13, 2015) and summer (Aug 7, 2015). The line-2 consisting of 51 stations is the most busy circular line in Seoul having the railway of 60.2 km length. The the one-day average $PM_{10}$ concentrations were $148{\mu}g/m^3$ in winter and $66.3{\mu}g/m^3$ in summer and $PM_{2.5}$ concentrations were $118{\mu}g/m^3$ and $58.5{\mu}g/m^3$, respectively. The $PM_{2.5}/PM_{10}$ ratio in the underground tunnel was lower than the outdoor ratio and also the ratio in summer is higher than in winter. Further the study examined structural types of underground subsections to explain the patterns of elevated PM concentrations in the line-2. The subsections showing high PM concentration have longer track, shorter curvature radius, and farther from the outdoor stations. We also estimated the outdoor PM concentrations near each station by a spatial statistical analysis using the $PM_{10}$ data obtained from the 40 Seoul Monitoring Sites, and further we calculated $PM_{2.5}/PM_{10}$ and $PM_1/PM_{10}$ mass ratios near the outdoor subway stations by using our observed outdoor $PM_1$, $PM_{2.5}$, and $PM_{10}$ data. Finally, we could develop pollution maps for outdoor $PM_1$ and $PM_{2.5}$ near the line-2 by using the kriging method in spatial analysis. This methodology may help to utilize existing $PM_{10}$ database when managing and control fine particle problems in Korea.
