The purpose of this paper is to investigate search efficiency of controlled vocabulary versus uncontrolled vocabulary subject access in online catalog systems. The question of the effectiveness of controlled versus uncontrolled vocabulary in information retrieval has been raised in many literatures. A debate continues in the Library and Information Science Professions over the relative merit, appropriateness, and efficiency of uncontrolled vocabulary subject access in online catalog systems. Actually users used to combine uncontrolled vocabulary subject searching with controlled vocabulary subject searching. But the success of user's subject search depends on his choice of search terms. Also the technical developments that facilitate cooperation among information services in general make it increasingly possible for such cooperation to take place on an international level. In this study, several common types of vocabularies on online catalog systems are described and compared, especially usages of vocabularies in multilingual environment are analyzed.

A system for the recognition of machine printed Arabic script is proposed. The Arabic script is shared by three languages i.e., Arabic, Urdu and Farsi. The three languages have a descent amount of vocabulary in common, thus compounding the problems for identification. Therefore, in an ideal scenario not only the script has to be differentiated from other scripts but also the language of the script has to be recognized. The recognition process involves the segregation of Arabic scripted documents from Latin, Han and other scripted documents using horizontal and vertical projection profiles, and the identification of the language. Identification mainly involves extracting connected components, which are subjected to Principle Component Analysis (PCA) transformation for extracting uncorrelated features. Later the traditional K-Nearest Neighbours (KNN) algorithm is used for recognition. Experiments were carried out by varying the number of principal components and connected components to be extracted per document to find a combination of both that would give the optimal accuracy. An accuracy of 100% is achieved for connected components >=18 and Principal components equals to 15. This proposed system would play a vital role in automatic archiving of multilingual documents and the selection of the appropriate Arabic script in multi lingual Optical Character Recognition (OCR) systems.

This study examines the use of the modals and quasi-modals of obligation and necessity, which involves the layering of must, should, have (got) to, got to, and need to in a corpus of cross-cultural communication between EFL learners. The study compares the EFL learners' corpus with a sub-corpus of ICE-GB in terms of token counts and semantic/functional distributions because International Corpus of Standard varieties of English serves as common reference points for international comparison of varieties of English. The results showed that must, should, and have to were the main players in both the corpus of EFL learners and that of native speakers. However, some discrepancy exists between EFL learners' corpus and the native speakers' corpus in the use of the modals and quasi-modals of obligation and necessity. Compared to the corpus of native speakers, the corpus of EFL learners was distinctively different in the relative unpopularity of have to and in the comparative popularity of must particularly for root meaning. Suggestions were made for using computer corpora in understanding EFL learners' language use. And pedagogical implications were made for teaching English modality considering the current usage of the modals and quasi-modals in Standard varieties of English and helping the students develop pragmatic competence.

The purpose of this paper is to investigate how the English classes in secondary schools in Korea are in terms of communicative nature. After literature study, COLT parts A and B were used to analyze three kinds of English classes: a common class type taught by a school teacher who had won 1st prize at TEE contest, a team teaching class taught by NNS and NS, and a model class taught by a pre-service English teacher. Their communicative English classes were videotaped and transcribed for analysis by COLT. The results of the study revealed that students participated in the classes mostly as a unit and, therefore, did not get many meaningful chances to speak English. Second, creative language-use opportunities were barely found during classes. Third, the group work seemed to be prepared before the class, not to be done during the class. Therefore it is likely to be learned from memorization rather than meaningful communication. These results suggest English classes in schools be more communicatively oriented for successful English learning. Further study should be conducted in order to make English classes more communicative to help students communicate their genuine messages in English and to help teachers teach English efficiently.

Background: Velopharyngeal insufficiency that accompanies speech resonance and articulation disorders can be managed through several intervention methods such as speech-language therapy, prosthetic aids, and surgery. However, for patients with severe hypernasality, surgical interventions are highly recommended. Among available surgical techniques, the posterior pharyngeal flap is most common. Case presentation: Two adult males with high nasalance scores underwent superiorly based posterior pharyngeal flap surgery, followed by speech testing by an expert speech-language therapist. Nasalance scores and articulation accuracy were assessed up until 1 year after the surgery. Nasalance scores were measured five times using a nasometer, after which the average value was calculated. Conclusions: Consistent declines in hypernasality over time are not easy to explain since the pedicled pharyngeal flap narrowed over time, secondary to cicatrization. However, scar tethering of the soft palate in a posterior direction could reduce the velopharyngeal port size over time. Therefore, long-term follow-up with intensive speech therapy is suggested for patients with severe hypernasality.

Purpose : This study was to develop Nursing Process Model of abdominal surgery patient using nursing diagnoses of NANDA, Nursing Interventions Classification(NIC), and Nursing Outcomes Classification(NOC). Method : The data in database were collected from nursing records in sixty patients with abdominal surgery admitted in a university hospital and open questionnaires of thirteen nurses. Systematic nursing process resulting from each nursing diagnoses, most common, was developed by the statistical analysis through database query from clinical database of abdominal surgery patients. Result : 51 nursing diagnoses were identified in abdominal surgery patients. The most commonly occurred nursing diagnoses were Pain, Risk for Infection, Sleep Pattern Disturbance, Hyperthermia, Altered Nutrition: Less Than Body Requirements in order. The linkage lists of NANDA to NIC and NANDA to NOC, and the nursing activities according to nursing diagnoses of abdominal surgery patients were identified in unit. Conclusion : Nursing Process of abdominal surgery patients was comprised of core nursing diagnoses, core nursing interventions, core nursing outcomes which provides the most reliable data in unit and could make nurses facilitate nursing process easily without full consideration of knowledge about nursing language classification system. Therefore, it could support nurses' decision making and recording of nursing process especially in the computerized patient record system if unit nursing process model using standardized nursing language system which contains of their own core nursing process data was developed.

Korean traditional fermented milk, Tarak, came down from the Koryo dynasty according to Korean ancient cookbook SoowoonJaabaang, which was written by Taakjunggong, Yoo Kim around AD 1500. Tarak is generally refers to milk or dairy products. Three theories on 'Tarak' revealed in this study are as follows: 1) it has been derived from Dolgwol language, tarak, 2) it has originated in Mongolian language, Topar(tarague), meaning horse's milk and 3) it originated in Tarak mountain located in Hanyang, which was capital of Chosun. In Mongolia, fermented milk has been called as Tarak and it has been called as tar by Yakuts tribe who are nomads in Sakha. The common part, tar, of these words is said to be the term representing the origin of the fermented milk coming from the central Asia. Therefore, Korean Tarak seems to be part of the central Asian culture that flowed into the Korean peninsula. The manufacturing method of Mogolian Topar(tarague) is similar to those of Tarak found in the SoowoonJaabaang. This research revealed that Korean traditional fermented milk, Tarak, is thought to be affected by the central Asia, especially Mongolia.

The development of distributed application in the standardized CORBA(Common Object Request Broker Architecture) environments reduces the developing time and maintaining cost of the systems. Because of these advantages, the development of application is being progressed in the several fields using the CORBA environments. The programmers in the CORBA environments usually develop the application programs using the CORBA IDL(Interface Definition Language). The IDL files are compiled by IDL compiler and translated into the stubs and skeleton codes which are mapped onto particular target language. The stubs produced by IDL compilers processes the marshaling a data into message buffer. Before a stub can marshal a data into its message buffer, the stub must ensure that the buffer has at least enough free space to contain the encoded representation of the data. But, the stubs produced by typical IDL compilers check the amount of free buffer space before every atomic data is marshaled, and if necessary, expand the message buffer. These repeated tests are wasteful and incidence of overheads, especially if the marshal buffer space must be continually expanded. Thus, the performance of the application program may be poor. In this paper, we suggest the way that the stub code is maintain the enough free space before marshaling the data into message buffer. This methods were analyzes the overall storage requirements of every message that will be exchanged between client and server. For these analysis, in the Front End of compiler has maintain the information that the storage requirements and alignment constraints for data types. Thus, stub code is optimized and the performance of application program is increased.

The purpose of this study is to investigate the aspect of production and perception of Korean vowels /${\Lambda}$/ and /o/ and to discuss the correlation between production and perception of the two vowels. For this purpose, two separate experiments were conducted. 19 Chinese learners and 20 Korean native speakers produced Korean vowels /${\Lambda}$/ and /o/. Production experiments indicated that Koreans and Chinese female groups revealed common features in production, showing that they all pronounced /${\Lambda}$/ and /o/ in a distinguishable manner in the acoustic space. On the other hand, the Chinese male group failed to show that they could pronounce two vowels distinctively. The Chinese male group seemed to be confused in vowel height between the two vowels. A perception experiment was carried out on a continuum consisting of 11 synthesized stimuli. The perceptual judgment from referred Chinese and Korean subjects showed that Koreans and Chinese female groups had the same phonological boundaries (stimulus '04') for the two vowels on the continuum. However, the Chinese male group made perceptual criterion on stimulus '03'. These results confirmed that there was strong correlation between the aspect of production and perception.
