Objectives: The aim of this study was to examine the debate on the use of medical devices between Western Medicine and Korean Medicine, as this is one of the greatest conflicts in Korea's medical profession. Judicial precedents and interpretations of authority serve as regulations because medical affairs law states that Korean Medicine practices are ambiguous. Method: We conducted a search in the Korean RISS, OASIS, and DBPIA databases using several keywords associated with medical devices, Korean Medicine, and Korean Medicine Doctors. The search period was until November 5 2021. The retrieved papers were classified according to the selection and exclusion criteria by checking the title, abstract, and text. For precedents, searches were done regarding comprehensive legal information, etc., and in the case of non-disclosure precedents, we requested access to the precedents by web-court requests. Results: A total of 80 documents were found as a result of the search, and 13 publications were included in the study. The selected publications were classified and analyzed by this research team into Korean medicine, Western medicine, and legal or state agency research. In the existing literature and judgments, the arguments that played a major role changed depending on the time the judgment was made. "Social conventions", "curriculum", "academic principles", and "health and hygiene dangers" were the key arguments. Conclusions: Further studies will be needed that can comprehensively arrange the existing literature and clinical results, and continuous study will be needed to verify that the use of medical devices by Korean medicine doctors is helpful for prognosis and accurate treatment of their patients.

Ability to find some information is the basic ability in information making activity. Even though students have been instructed how to search information, however, they don't reach a certain level. For improving ability to make information, it needs to be connected to Korean and Social education. Therefore, this paper analyzes the contents of related-subjects to internal and external curriculum of computer education, and develops the program to improve ability to make information, selecting learning point for improving ability to make information.

There are invisible defects by naked eyes in ceramic material images such as internal stomata, cracks and foreign substances. In this paper we propose a method to detect and extract such defects from ceramic pipe weld zone by applying ART2 learning. In pre-processing, we apply Ends-in Search Stretching to enhance the intensity and then perform fuzzy binarization with triangle type membership function followed by enhanced ART2 that interacts with random input patterns to extract such invisible defects. The experiment verifies that this proposed method is sufficiently effective.

The purpose of this paper is to investigate the domain authority, number of webpages, links, and calculate the web impact factor of six public libraries of India which are fully funded by Ministry of Culture with the supervision of administration. The data for the study were collected from websites of concerned libraries with the help of a suitable search engine, Open Site Explorer. The study found that the highest domain and page authority was recorded by Khuda Baksh Oriental Public Library and National Library, respectively. It also further revealed that excepting the two libraries, i.e., Khuda Baksh Oriental Public Library and Delhi Public Library, the internal equity-passing links and total internal links of rest of the libraries is zero. National Library leads with maximum total links and total equity-passing links, also with the highest followed linking root domains, total linking root domains, and linking C blocks, and concludes with the web impact factor of Central Secretariat Library recording the maximum, followed by National Library and Khuda Baksh Oriental Public Library.

In this paper, we propose the index structure based on a vector approximation for efficiently supporting the similarity search of multi-dimensional data. The proposed index structure splits a region with the space partition method and allocates to the split region dynamic bits according to the distribution of data. Therefore, the index structure splits a region to the unoverlapped regions and can reduce the depth of the tree by storing the much region information of child nodes in a internal node. Our index structure represents the child node more exactly and provide the efficient search by representing the region information of the child node relatively using the region information of the parent node. We show that our proposed index structure is better than the existing index structure in various experiments. Experimental results show that our proposed index structure achieves about $40\%$ performance improvements on search performance over the existing method.

Demand for better services in the Internet has been increasing due to the rapid growth of the Internet, and hence next generation routers are required to perform intelligent packet classification. For a given classifier defining packet attributes or contents, packet classification is the process of identifying the highest priority rule to which a packet conforms. A notable characteristic of real classifiers is that a packet matches only a small number of distinct source-destination prefix pairs. Therefore, a lot of schemes have been proposed to filter rules based on source and destination prefix pairs. However, most of the schemes are based on sequential one-dimensional searches using trio which requires huge memory. In this paper, we proposea memory-efficient two-dimensional search scheme using source and destination prefix pairs. By constructing binary prefix tree, source prefix search and destination prefix search are simultaneously performed in a binary tree. Moreover, the proposed two-dimensional binary prefix tree does not include any empty internal nodes, and hence memory waste of previous trio-based structures is completely eliminated.

This study analyzed academic information seeking behavior, focusing on university students, the main users of the university library, to derive considerations for the development and improvement of the subject guide of the university library. As a result of the analysis, university students highly evaluated their subjective information seeking ability, but it was found that it was difficult to set specific search terms. The purpose of using academic information is specific, and it has been shown that there is a tendency to perform all information search activities in one database. In addition, when selecting information resources, reliability, suitability, and recency are primarily taken into consideration. Awareness of university libraries and subject guides was generally low, but their reliability was found to be high. Based on this, it is necessary to consider the classification of information sources according to specific information seeking purposes, the composition of information resources, explanatory element technology related to information resource selection criteria, comprehensive database, topic keyword recommendation, library marketing, and close cooperation with internal institutions.

The purpose of this research is to study the efficiency of the Internet market, not provided to consumers by the existing traditional market. This research examines whether consumers properly understand the efficiency of the Internet market. The result from consumers perception on the efficiencies in the two market are as follows. First, consumers perceived the traditional market as having more product alternatives compared to the Internet market. Second, consumers perceived that the Internet market was more efficient in price dispersion and price change Third, the Internet market was considered more efficient in searching and travel time, and in the search cost. Finally, the traditional market was considered as a better provider of the information about product function, feature, reality, usage and service compared to the Internet market. On the contrary, the Internet market turned out to be more effective in providing product information, price information and trading information compared to the traditional market. Therefore consumers perceived the traditional market of having more information.

In order to solve the difficulties of parameter settings in SA algorithm, an improved practical SA algorithm is proposed by employing the threading techniques, appropriate software structures, and dynamic adjustments of temperature parameters. Threads provide a mechanism to realize a parallel processing under a disperse environment by controlling the flux of internal information of an application. Thread services divide a process by multiple processes leading to parallel processing of information to access common data. Therefore, efficient search is achieved by multiple search processes, different initial conditions, and automatic temperature adjustments. The proposed are methods are evaluated, for three types of Traveling Salesman Problem (TSP) (random-tour, fractal-tour, and TSPLIB test data)are used for the performance evaluation. The experimental results show that the computational time is 5％ decreased comparing to conventional SA algorithm, furthermore there is no need for manual parameter settings. These results also demonstrate that the proposed method is applicable to real-world vehicle routing problems.

To test all internal faults in the case that the number of Primary Input is N, we need patterns that are composed of PI's of maximum 2N. In this paper, we proposed the method to reduce a search space by dividing the multiple output circuit into subcircuit that is related with output. And this method, called PBM(Partition-Based Method), can generate a set of test pattern. The method can effectively generate a test pattern for evaluating all fault of circuit, because the length of input pattern is smaller than that of full circuit and PBM doesn't search any signal line that is not concerned with detecting fault.
