Collaborative filtering has been most widely used in commercial sites to recommend items based on the history of user preferences for items. The basic idea behind this method is to find similar users whose ratings for items are incorporated to make recommendations for new items. Hence, similarity calculation is most critical in recommendation performance. This paper presents a new similarity measure that takes each rating of a user relatively to his own ratings. Extensive experiments revealed that the proposed measure is more reliable than the classic measures in that it significantly decreases generation of extreme similarity values and its performance improves when consulting neighbors with high similarites only. In particular, the results show that the proposed measure is superior to the classic ones for datasets with large rating scales.

Objectives : The purpose of this study was to demonstrate the effectiveness and availability of salt pharmacopuncture of Korean sun-dried salt and processing salt on the basis of bibliographical review. Methods : This study was done through a narrative review of related bibliography including medical books, journals, general bibliography, and web sites. Results : 1. Korean sun-dried salt is produced in the ground with soil, tiles, and pottery. Sun-dried, traditional, granulated, bamboo, and grilled salts are all appropriate for medical use. They are composed of a lower level of NaCl and unnecessary substances, and have a higher water and mineral content. 2. The 9~30 g of NaCl included in the physiological saline matches the ratio of a normal human body. However, if the saline is used for water supply, it should be improved because the recommended amount is much lower. 3. Medicine that includes NaCl is applied for lessening the congestion of the nasal cavity, alleviating cornea swelling, or for a lack of water. NaCl can also be used for washing contact lenses as well as cleaning the mucous membrane of the eyes and nose. 4. Salt relieves anger, detoxifies, induces vomiting, builds strong muscles and bones, gives energy, slows aging, and ultimately improves health. 5. Salt treats many diseases including: cardiovascular, hematosis, respirometer, obstetric, musculoskeletal, mineral supplement, eye, teeth and skin issues, etc.. However, salt is not used for treating asthma, cough, or other ailments mainly affecting the vascular system. 6. While NaCl in salt absorbs water and the vascular constriction results in higher blood pressure, the pressure induced from salt is actually a physiologically temporary rise. Rather, salt helps remove oil from the body and its potassium lowers blood pressure. Conclusions : It was suggested that salt pharmacopuncture of Korean sun-dried salt and processing salt should be made available for adjusting the physiological salt concentration and control of the Na side effects, therefore it would be useful in the treatment of diseases.

The normal tissue in radiation therapy, to minimize radiation, it is most important to maximize local tumor control rates in intensive research the exact dose to the tumor sites. Therefore, the initial, therapist accuracy of detecting movement of the patient fatigue therapist has been a problem that is weighted down directly. Also, by using a web camera, a difference value between the image to be updated to the reference image is calculated, if the result exceeds the reference value, using the system for determining the motion has occurred. However, this system, it is not possible to quantitatively analyze the movement of the patient, the background is changed when moving the treatment bed in the co-therapeutic device was not able to sift the patient. In this paper, using a alpah(${\alpha}$) filter index is an attempt to solve these limitations points, quantifies the movement of the patient, by separating a background image of the patient and treatment environment, and movement of the patient during treatment It senses only, it was possible to reduce the problems due to patient movement.

Currently, there are many simple searches for local culture and tourism, but systematic information retrieval using ontology technology is weak. The keyword-based search, which is an existing search method, derives a search result that is different from a user's wanted intention. On the other hand, semantic search using ontology constructs shows the information related to the search term by creating a relation between words and words. Therefore, when tourists search for cultural and tourist attractions in the area, they provide information that includes meaning relevance in the search results. If the ontology provides information on the culture, sightseeing area, transportation, Can be more easily grasped. In this paper, we propose an ontology-based retrieval system based on culture and tourist sites utilizing public institutions database by using mobile application by extending search system which relied only on existing internal database to provide accurate and reliable information to users. This efficient structure of the ontology makes it possible to provide information suitable for the user quickly and accurately.

The purpose of this study was to investigate the status of agricultural management accounting information, education status, and policy demands through a questionnaire survey of advanced agricultural managers. These people are expected to play a key role in the changing agricultural environment in Korea. Based on survey results, several policy implications were derived for the advanced agricultural managers' agricultural management accounting information record activation. Survey results of 303 respondents identified that 63.4% of them record their agricultural management accounting information. The biggest reason given for not recording this information was lack of time for record keeping. The biggest problem was a 'lack of Question and Answer system'. In addition, 37.2% of the respondents were not aware of the current agricultural accounting guidelines. In terms of education, 71.3% of the respondents have completed course work in accounting and responded that an 'On-off parallel education system', which offers both online and offline classes, was the most effective method to prevent dropout. Respondents thought that agricultural management accounting records were helpful for the management of agriculture and their participation in government policies. They also thought that customized education programs should be further implemented for enhancing the effectiveness of education programs, and 'One-stop Question and Answer system on related web sites and organizations' is required for them to keep better records. The following policy implications can be derived from the survey results. First, interoperability between agricultural management accounting information recording programs is needed. Second, accessibility should be strengthened. Third, the education system needs to be improved. Fourth, voluntary participation should be encouraged. Last, the government needs to establish a post-verification system.

Global commerce is apparently here to bind Korean firms as well as Koreans. The advertising, buying and selling of goods and services recognizes no borders. As a result, enforcing territorially based trademark rights has become ever more challenging. Remote trademark owners who peacefully coexisted in a time before the internet and increasing globalism are now bumping heads. The internet also has made it easier for unscrupulous operators to deceive consumers and divert customers from established businesses by misappropriating trademarks on web-sites and in domain names. U.S. federal courts have been willing to help American businesses halt trademark infringements that reaches outside the United States. This is particularly true for e-business, via the internet, and the trend toward enforcement seems to be in favor of the trademark owner. This article discusses this trend as well as the extraterritorial enforcement of trademark rights by U.S. courts under the Lanham Act. It also offers suggestions for protecting valuable trademark rights worldwide. This paper will contribute to global Korean firms and Koreans who carefully read arguments in this valuable literature.

This study was conducted on the visitors regarding their usage and evaluation state of the interpretive media which is utilized as a self-guide environment interpretation for the purpose of accumulating basic data for the park management. A questionnaire survey was chosen and the 275 valid samples among them were analyzed. The socioeconomic and behavioral characteristics of the visitors turned out to be similar with the results from another visitor survey in the same site. Among those who used the interpretive media, the largest proportion(77%) used the information board resources of the park; the usage rate of interpretive labels of woody plants, interpretive signs of cultural assets, and LED signs were shown to be relatively high. The usage of park brochures, park web sites, visitor center exhibits, and bulletin boards were less than 40% each. Visitors were asked to evaluate the importance and performance of the nine interpretive medias using a Likert Scale whose value ranges from one to five. The result recorded averaged above 4, which proved that the respondents were perceiving the importance of all forms of interpretive media greatly. The performance of interpretive media was also evaluated as affirmative, except the visitor center exhibits.
