The Korean government has acknowledged the importance of Dokdo Island and has consequently taken various measures for the effective management of it. There has, however, been little quantitative information about the value of Dokdo Island and this study, therefore, attempts to assess the Islands non-market value. To this end, this study estimated the non-market value by MAUT/CVM. The non-market value estimated by MAUT/CVM includes historic value, military value, ecological value, and geological value. According to the results, the values calculated by the price in market is about 10.37 trillion won and the values estimated by MAUT/CVM is about 1.72 trillion won annually.

A new association rule mining algorithm, which reflects the strategic importance of associative relationships between items, was developed and presented in this paper. This algorithm exploits the basic framework of Apriori procedures and TSAA(transitive support association Apriori) procedure developed by Hyun and Choi in evaluating non-frequent itemsets. The algorithm considers the strategic importance(weight) of feature variables in the association rule mining process. Sample feature variables of strategic importance include: profitability, marketing value, customer satisfaction, and frequency. A database with 730 transaction data set of a large scale discount store was used to compare and verify the performance of the presented algorithm against the existing Apriori and TSAA algorithms. The result clearly indicated that the new algorithm produced substantially different association itemsets according to the weights assigned to the strategic feature variables.

This study is concerned with the importance of TQM factors, and their characteristics on quality management. Key aspects of management commitment and ploicy, quality department and communication, equipment and material management, training, and employee relations etc. in TQM measurement, their theoretical background and employee perception about their importance intensively are investigated. In the importance of TQM, quality department and communication, quality and reporting, and rpoduction process management appeared to have a low rating while management commitment and quality policy, internal customer and supplier have a comparatively high value. And some perception for these factor showed difference between production and non-production department; internal customer and supplier, production process management, and employee relation.

Objectives: This study was conducted to examine the status of foodservice management, with special interest on sanitary and nutritional food service in elderly day care centers. Methods: A total of 79 employees who managed foodservice facilities in elderly day care centers were included in the survey. The contents of the questionnaire consisted of general characteristics, importance and performance of sanitary and nutrition management, the reasons for poor performance, factors necessary for improvement, and the employee's demand for support. Data analysis was conducted using the SPSS v25.0. Results: Sanitary management showed an average importance score of 4.84 ± 0.40 and a performance score of 4.70 ± 0.61 (t-value: 8.260). The item with the lowest performance score was personal sanitary management (4.58 ± 0.71). In nutrition management, the average importance score was 4.52 ± 0.68, and the performance score was 4.20 ± 1.00 (t-value: 9.609). There were significant differences between the average score of importance and performance in both areas. As a result of an Importance-Performance Analysis, items that were recognized as important but had relatively low performance was "personal hygiene", "ventilation" and "food storage". Also in the nutritional management area, "menu planning for disease management" and "checking the saltiness in the soup" etc. had very low performance with low importance recognition. The items shown in the "low priority" quadrant were those that required professional management skills. In the areas that demanded support in foodservice management, education about sanitary and safe institutional food service had the highest score (4.42 ± 0.74), and all other items showed a demand of 4 points or more. Conclusions: Foodservice managers recognize the importance of foodservice facility management but performance is relatively low. Institutional support is, therefore, needed to improve performance. For items with low importance, it seems necessary to improve awareness of the necessity of these items and to provide education in this regard. To gradually improve foodservice management, continuous provision of education and training in these areas are of great importance.

The cell loss probability recommended in the B-ISDN is in the range $10^{-8}~10^{-12}$. When a simulation technique is used to analyze the performance of the ATM node, an enormous amount of computer processing time is required. In this study, we derive an importance sampling simulation technique that can be used to evaluate the performance of the ATM node very quickly, that is, the probability that the queue size at the ATM node reaches some large value N. The simulation results show that the backlog probability obtianed by the importance saimpling simulation is very close to that obtained by the ordinary simulation and the computer time can be reduced drastically by the importance sampling simulation.

Shareholders solely depend on annual reports to make investment, credit and other decisions. Investors expect that information should be reliable, relevant, comparable, consistent and thus easy to use for decision making. But whether the importance of annual reports to all shareholders is equally significant is a question of research. Thus, this research study tries to find out the importance of reading annual reports to the investors. A questionnaire survey is conducted on investors considering thirty one general shareholders and six brokers. This research based survey finds that most of the shareholders have no knowledge about accounting or finance and they have little knowledge about capital markets due to lack of training. This study also finds that general shareholders read an annual report at least moderately except value added statement, chairman's review, director's report and rumor. This study recommends human resource should be developed through adequate training, and annual reports should provide transparent and quality information which will ultimately increase the confidence of investors.

In this study, we tried to analyze the relative importance of features for various functions provided by Discovery. We identified a total of 36 assessment items in five categories including contents, search function, serendipity, interactivity, and ease of use based on literature review. In order to objectively evaluate the relative importance of each evaluation element, an AHP technique was adopted. As a result, 'Easy of use' received the highest weighted value among the five categories, followed by 'contents', 'search function', 'interactivity', and 'serendipity'. In addition, among all the 36 assessment items, 'Quality of data for central index' had higher weighted value. These findings can be used as basic data to adopt a discovery tool for libraries.

Due to the growing importance of ESG management, various studies have been conducted to explore the relationship between ESG performance and corporate value. The purpose of this study is to investigate how a company's ESG performance impacts its corporate value. The research findings indicate that there is difficulty in explaining the relationship between ESG performance of Korean IT companies and firm value in a straightforward manner. However, the results demonstrate that companies with higher profitability, higher foreign ownership, and higher R&D expenditure tend to have a positive impact of ESG ratings on corporate value. Based on these results, we can infer that Korean IT companies can enhance their corporate value by increasing R&D investments to develop innovative products that improve profitability. Additionally, attracting higher foreign investments can also positively influence ESG performance and subsequently increase corporate value. Acknowledging these factors can help companies realize the significance of ESG performance in elevating their overall corporate value.

Radicoid structure of herbaceous communities in Mt. Kumbyung, Chunchon, Kangwon-Do was clarified emphasizing on the dominance of clonal plants in relation to vegetation development. In the total vegetation, 46% species identified were rhizomatous, 26% were species with tap roots, and 13% were stoloniferous species. Thus, all clonal species, including plants with bulb, corm and tuber, covered 62.8% of the total species. in the understory of Quercus, Pinus and Larix forests, 68.2% were clonal, which means 5% more compare to total vegetaion. Dominance of clonal plants became more conspicuous as their importance value was calculated. That is, they covered average 86% for the following three communities: 85% in Quercus, 95% in Pinus, and 76% in Larix, Especially, the rhizomatous plants were remarkable. Overall, clonal species dominated over the other radicoid types in terms of not only the number of species, but also the importance value. Dominance of these species was more peculiar in understory of forests, indicating the occupancy of clonal plants was related to the vegetation development.
