  • This study was conducted to compare the composition table of Korean food with that of foreign food. Analysis was made for Korean food composition table($5^{th}$ revision), Korean food composition table in Appendix of Recommended Dietary Allowances for Korean(6$^{th}$ th/ edition), Standard tables of food composition in Japan($5^{th}$ revised edition) and USDA Composition of Foods - Raw, Processed, Prepared. The method of content analysis was applied for this study and such differences were pointed out as the classification of food items, food items enlisted, the content unit of food and food components presented etc. To improve Korean food composition table, new food items and components should be added and old food items be eliminated based on the change of people's food consumption pattern. Also analysis for the domestic foods consumed by local people should be accomplished rather than borrowing foreign country's data.

  • The transaction tables of the existing association algorithms have two column attributes : It is composed of transaction identifier (Transaction_id) and an item identifier (item). In this kind of structure, as the volume of data becomes larger, the performance for the SQL query statements came applicable decreases. Therefore, we propose advanced association rules algorithm of n-items which can transact multiple items (Transaction_id, Item 1, Item 2…, Item n). In this structure, performance hours can be contracted more than the single item structures, because count can be computed by query of the input transaction tables. Our experimental results indicate that performance of the n items structure is up to 2 times better than the single item. As a result of this paper, the proposed algorithm can be applied to internet shopping, searching engine and etc.

  • A cross docking operation involves multiple inbound trucks that deliver items from suppliers to a distribution center and multiple outbound trucks that ship items from the distribution center to customers. Based on customer demands, an inbound truck may have its items transferred to multiple outbound trucks. Similarly, an outbound truck can receive its consignments from multiple inbound trucks. The objective of this study is to find the best truck spotting sequence for both inbound and outbound trucks in order to minimize total operation time of the cross docking system under the condition that multiple visits to the dock by a truck to unload or load its consignments is allowed. The allocations of the items from inbound trucks to outbound trucks are determined simultaneously with the spotting sequences of both the inbound and outbound trucks.

  • In our previous research, we proposed a tag emotion-based item recommendation scheme. The ternary associations among users, items, and tags are described as a three-order tensor in order to capture the emotions in tags. The candidates for recommendation are created based on the latent semantics derived by a high-order singular value decomposition technique (HOSVD). However, the tensor is very sparse because the number of tagged items is smaller than the amount of all items. The previous research do not consider the previous behaviors of users and items. To mitigate the problems, in this paper, the item-based collaborative filtering scheme is used to build an extended data. We also apply the probabilistic ranking algorithm considering the user and item profiles to improve the recommendation performance. The proposed method is evaluated based on Movielens dataset, and the results show that our approach improves the performance compared to other methods.

  • The purpose of this study was to analyse the qualitative and quantitative characteristics of paper-pencil tests for exploring its appropriateness as a selection tool of the gifted in science. For this purpose, we developed two (internal and external) item analysis frameworks, and applied these frameworks to analyse qualitative characteristics. Also, we analysed the relationship between two characteristics. The results of analysing qualitative characteristics revealed that the portion of items with acceleration context exceeding middle school curriculum level was relatively large, which caused low content validity. Furthermore, there was considerable deviation in content and context by subject matter and year, which caused test unstability. Items measuring knowledge domain was the most prevalent, and too much weight on data interpretation & analysis domain in inquiry process skills. In case of creativity test, the portion of items measuring convergent thinking was much larger than that of divergent or associative thinking. Most of these items were represented by using pictures and tables rather than using graphs. Item types of multiple-choice and short answers were superior to essay types. Discrimination index, on the whole, was appropriate (above 0.3), but item difficulty showed a vast deviation ($0.01{\sim}0.90$). Correlation coefficients among subject matters and test tools were very low, and test reliabilities were also low. Low item difficulty & high discrimination index item types were distinguishable. Items with acceleration context were more discriminating than enrichment context. Implications of developing quality paper-pencil test items in the selection of gifted students are discussed.

  • We re-classified traditional medicinal prescriptions in Dong-Eui-Bo-Gam for the modern application using Tradimed database. They could be devided into 6 categories by the definitions of the related laws. Herbal ethical drugs are the majority, 3926 items, account for 60.21% of total items. Herbal Health Functional Foods stands second, 1480 items, 22.70%, Herbal over the counter drugs are 893 items, 13.69%. These three categories are about 83% of total items. Herbal medical supplies are 158 items, 2.42%, Herbal medical tools are 44 items, 0.67%, Herbal cosmetics are 20 items, occupied 0.31 %. Therefore we have known that traditional medicinal prescriptions can be used not only as drugs, but also as funtional foods, cosmetics, and tools. So they should be developed as modern products to make best use of them. And we suggested that we need official criteria of herbs of careful use and higher standards for herbs which can be used as foods.

  • This study was conducted to develop a sexual satisfaction tool for married women in Korea. The data was collected from July 19 to Aug 18, 1997 by means of questionnaires developed by researchers. The subject were 417 married women living in Seoul and Pusan. The process of this study was as follows : 1) The concept of sexual satisfaction was defined. 2) A conceptual framework was identified based on the extensive review of relevant literature and interviews with married women. 3) The preliminary question items containing the attributes and elements of the concept of sexual satisfaction were listed. 4) The preliminary items were revised after a pilot study. 5) The Index of Content Validity(CVI) was calculated from the content specialists' rating. 6) The reliability and validity of the sexual satisfaction measurement tool were tested. As a result of the item and factor analysis, 17 out of 30 items were found to be valid, consequently could be used to measure sexual satisfaction for married women. These final 17 items were divided into two factors. These factors were labeled as "situation factor" (10 items) and "response factor"(7 items) according to the attributes of the clustered items. The reliability of the final 17 items was .9118. Further research is needed to confirm the reliability and validity of the tool by applying it to a group of healthy married women and to a group of married women having health-related problem.
