  • We introduce the forecasting method for a next day electric peak load that uses the optimal combination of two types of neural networks. First network uses learning data that are past 10days of the target day. We name the neural network Short Term Neural Network (STNN). Second network uses those of last year. We name the neural network Long Term Neural Network (LTNN). Then we get the forecasting results that are the linear combination of the forecasting results by STNN and the forecasting results by LTNN. We name the method Combination Forecasting Method (CFM). Then we discuss the optimal combination of STNN and LTNN. Using CFM of the optimal combination of STNN and LTNN, we can reduce the forecasting error.

  • Name separation (splitting full names into surnames and given names) is not a tedious task in a multiethnic country because the procedure for splitting surnames and given names is ethnicity-specific. Malaysia has multiple main ethnic groups; therefore, separating Malaysian full names into surnames and given names proves a challenge. In this study, we develop a two-phase framework for Malaysian name separation using deep learning. In the initial phase, we predict the ethnicity of full names. We propose a recurrent neural network with long short-term memory network-based model with character embeddings for prediction. Based on the predicted ethnicity, we use a rule-based algorithm for splitting full names into surnames and given names in the second phase. We evaluate the performance of the proposed model against various machine learning models and demonstrate that it outperforms them by an average of 9%. Moreover, transfer learning and fine-tuning of the proposed model with an additional dataset results in an improvement of up to 7% on average.

  • A choice of a term represent the contents of the documents should be preceded in recognition of the name of an individual. The recognition of the name of an individual which has high reliability can raise the building of information extract system into higher level. Up to now active research on the recognition of the name of an individual human name and the general recognition of the name of an individual have been studied, detailed research on the recognition of the name of a place hasn't be done, however. This thesis suggests detailed methods of recognition of Korean place names system with applying a rule made manully.

  • Generally, the Internet Address Resources Act is intended to protect the public from acts of Internet "cybersquatting", a term used to describe the bad faith, abusive registration of Internet domain names. In determining whether a person has a bad faith intent, a court may consider factors such as, (1) the trademark or other intellectual property rights of the person, if any, in the domain name, (2) the extent to which the domain name consists of the legal name of the person or a name that is otherwise commonly used to identify that person, (3) the person's prior use, if any, of the domain name in connection with the bona fide offering of any goods or services, (4) the person's bona fide noncommercial or fair use of the mark in a site accessible under the domain name, (5) the person's intent to divert consumers from the mark owner's online location to a site accessible under the domain name that could harm the goodwill represented by the mark, either for commercial gain or with the intent to tarnish or disparage the mark, by creating a likelihood of confusion as to the source, sponsorship, affiliation, or endorsement of the site, (6) the person's offer to transfer, sell, or otherwise assign the domain name to the mark owner or any third party for financial gain without having used, or having an intent to use, the domain name in the bona fide offering of any goods or services, or the person's prior conduct indicating a pattern of such conduct.

  • Objective : The purpose of this study is to analyze the naming of 'A diagnostic system based on Shanghanlun six meridian patterns and provisions' and to suggest an alternative naming. Methods : 1. The meaning of 'Six meridian(六經)' was reviewed on existing theories and Shanghanlun provisions. 2. Comparing the name of diangostic system with the term in 'Korean Standard Classification of Diseases-6(KCD-6)' and term in 'WHO international standard terminologies on traditional medicine in the western pacific region' was done. Results : 'Six meridian' is customary used in the Shagnhanlun study but its meaning is not match with original Shanghanlun system and could possibly make misunderstanding. So 'Disease pattern identification' is suitable than 'Six meridian' for this diagnostic system. Conclusions : This study suggests that using 'A disease pattern identification diagnostic system based on Shanghanlun provisions.'is more appropriate instead of using the name of the six meridian diagnostic system.

  • In the royal publishing process of the Joseon Dynasty, the main species of wood used for woodblock printing was recorded as Jajak-mok. Although the name Jajak-mok may suggest Jajak-namu(white birch), it is presumed to refer to a different type of wood than Jajak-namu based on its recorded habitat and usage in historical documents. The aim of this paper is to clarify that during the Joseon Dynasty, the term Jajak-mok referred to Geojesu-namu (Korean birch), while Jajak-namu was called Hwa-mok(樺木). Additionally, this paper explores how the term Jajakmok eventually became the name of white birch, Jajak-namu, used today. In the mid-18th century, Japan used the character 樺(hwa) to refer to Beot-namu(Sargent cherry). As Japanese encyclopedias entered Joseon, the term Hwa-mok began to refer to both Beot-namu and Jajak-namu, which is also called Bot-namu. Since the pronunciation of Boet-namu and Bot-namu are similar, the two trees were eventually unified under the name Boet-namu. In the 20th century, the official names of three trees were established. According to notifications issued by the Ministry of Agriculture and Commerce of the Korean Empire in 1910 and the Governor-General of Chosen in 1912, Hwa-mok(white birch) was renamed asJajak-namu. In 1968, Beot-namu(Sargent cherry) retained its original name, and Jajak-mok(Korean birch) was remained . In modern Chinese character dictionaries, the meaning of 樺(hwa) is listed as "1. Beot-namu(Sargent cherry), 2. Jajak-namu(white birch)." From this, we can infer the historical background in which the names of these three trees were mixed up.

  • The Korean medicinal plant name written in Chinese script, Jingyo, is somewhat confusingly used in the Korean modern literature. This name was assigned to at least three species, with examples being Gentiana macrophylla, Aconitum pseudolaeve, and Justicia procumbens. To clarify the taxonomic identity of Jingyo, these names were examined based on the Chinese classics and Korean classics and compared them with the modern flora of both China and Korea. In China, Jingyo was considered as Justicia gendarussa or Gentiana macrophylla. In Korea, Jingyo was considered as A. pseudolaeve or J. procumbens. However, it was concluded that Jingyo is not distributed on the Korean Peninsula. In addition, although the Hangeul name Jinbeom was the result of the misreading of the Chinese script Jinbong, another Chinese term for Jingyo, this name is used in many modern studies related plant taxonomy. Hence, we also propose Jinbeom as the conserved Hangeul name of A. pseudolaeve.

  • This paper proposes a method of player event retrieval using combination of two functions: detection of player name in speech information and detection of sound event from audio information in golf videos. The system consists of indexing module and retrieval module. At the indexing time audio segmentation and noise reduction are applied to audio stream demultiplexed from the golf videos. The noise-reduced speech is then fed into speech recognizer, which outputs spoken descriptors. The player name and sound event are indexed by the spoken descriptors. At search time, text query is converted into phoneme sequences. The lists of each query term are retrieved through a description matcher to identify full and partial phrase hits. For the retrieval of the player name, this paper compares the results of word-based, phoneme-based, and hybrid approach.

  • As one of the trials for a systematic approach to mathematics terms which occupies an important place in teaching and learning mathematics, compositions of listed terms in 2011 elementary mathematics curriculum in Korea are discussed in this study. To this end, listed terms are classified in view of three points and looked for their characteristics, from which implications are found out for elementary mathematics teaching and learning First of all classifications into grade-group and domain-specific terms, then into newly coined terms and terms from everyday life, and then into korean terms and chinese character terms and english terms are attempted. Next, terms with a kernel and terms without a kernel are distinguished, and in this process, term-sets are presented. Finally, object terms, operation terms, relationship terms, measure terms, conditions terms, graphics terms, name terms are classified. Based on these results, the following implications for elementary mathematics teaching and learning are suggested. First, it should be considered that many of the listed terms in 2011 curriculum are newly coined and chinese character terms. Second, the interconnections between terms should be considered. Third, a variety of roles and functions of the terms should be considered.

  • This paper analyzes information on Augmented Widen the Core Powder (加味普正散) (AWCP) in the Dr. Kim Young Hoon's medical record database, Cheongang Medical Records. AWCP is a prescription that is not found in the existing medical texts, yet is referred to in Dr. Kim Young Hoon's medical record database. By examining these records, this study shows that the original prescription for AWCP was Decoction for Rectifying the Qi with Cyperus and Kudzu (香葛正氣飮) and that this prescription was deeply related to Rectify the Qi Powder Worth More Than Gold (不換金正氣散) as well as Cyperus and Kudzu Decoction (香葛飮). In addition, AWCP had several names over a long period of time, and its name changed from the Powder of Relieving Lives and Rectifying the Qi (普救正氣散) to AWCP. In particular, this study shows that the term 'gami' (加味 augmented) indicates a change in prescription name, not a change in the composition of the prescription.
