The purpose of this study was to establish and apply 'term learning strategy' for learners whose basic skill, interest, and motivation for learning is lower, and to increase the learned capabilities of subjects' 'industry introduction', required for industrial technical high school students. Another purpose was to identify when the learning strategy established was applied, its affect on how well learners understood terms in a particular unit of material, and, after instruction presented in accordance with 'term learning strategy,' evaluate the ease with which subjects understood the teacher's explanation of the unit of subject, how well they understand the main concepts of the unit of subject, and to what extent the presentation interested and motivated the subjects. The researcher established 'term learning strategy' based on the principles of Garg's "Nine Steps for Events of Instruction." The study included 35 first grade participants purposely selected from 33 classes at 1155 students in K industrial technical highschool. Data was collected via tests and surveys. Results indicated that 'term learning strategy' facilitated thorough understanding of terms and concepts related to the unit of subject, as well as a better understanding of the teacher's explanation and increased interest and motivation in learning. In addition, the "term learning strategy" increased interaction among learners in the instruction setting. Finally, implications of this study and implementation recommendations for this instructional strategy were presented.

Today, apartment houses account for a very high proportion of the types of residence. This study aims to present basic data for preparing a reasonable distribution plan by identifying factors considered in calculating the amount of collection of management fees. After reviewing previous studies on common management fees and long-term repair allowances, various data on apartment houses subject to mandatory management in Busan in 2020 were collected from the Apartment Management Information System to analyze the differences in influencing factors according to type of apartment management(self-governing management, consignment management). As a result of statistical analysis, the number of households and many construction elapsed periods had a negative(-) effect on long-term repair allowances, and many construction elapsed periods had a negative(-) effect on common management fees. In addition, the degree to which many construction elapsed periods had a negative(-) effect on long-term repair allowances and common management fees had less impact on consignment management than on self-governing management. And the long-term repair allowances were imposed less by consignment management, common management fees were charged less by self-governing management. The results of this study will serve as basic data for rational distribution of long-term repair allowances and common management fees to residents and managers of apartment houses subject to mandatory management in Busan.

The majority of text categorization systems use the term-based classification method. However, because of too many terms, this method is not effective to classify the documents in areal-time environment. This paper presents a real-time concept-based text categorization system,which classifies texts using thesaurus. The system consists of a Korean morphological analyzer, athesaurus tool, and a probability-vector similarity measurer. The thesaurus tool acquires the meaningsof input terms and represents the text with not the term-vector but the concept-vector. Because theconcept-vector consists of semantic units with the small size, it makes the system enable to analyzethe text with real-time. As representing the meanings of the text, the vector supports theconcept-based classification. The probability-vector similarity measurer decides the subject of the textby calculating the vector similarity between the input text and each subject. In the experimentalresults, we show that the proposed system can effectively analyze texts with real-time and do aconcept-based classification. Moreover, the experiment informs that we must expand the thesaurustool for the better system.

Purpose: We reviewed all the articles on effect of smoking cessation intervention to find out the way of improvement of it. Method: 48 researches were published in Korean journals from 1980 to 2007. The research were analyzed according to: major of first author, subjects, application of theoretical framework, contents of intervention, a term of intervention, the time of evaluation on effect of interventions, research design, dependant variables, and effect of interventions. Results: Research on effect of smoking cessation intervention increased rapidly in the 2000's. At this time. 72.9% of research was published. Most of research subject were students. Theoretical framework were applied in 20.8% of articles. The most common intervention was education(39.4%). The effect of combined program on outcome variable was found to be stronger than only education program. Experimental design was used in 29.2% and quasi-experimental design was adapted in 43.8% of articles. 1- 6months intervention was in 35.4%. The long term intervention more than 1month was found to be effective. Health behavior related index was measured as a dependant variable in 62.3%. conclusion: Accordingly, long term program to apply to various subject is needed.

The Inverse Document Frequency (IDF) weighting method is based on the hypothesis that in the document collection the lower the frequency of a term is, the more important the term is as a subject word. This well-known hypothesis is, however, somewhat questionable because some low frequency terms turn out to be insufficient subject words. This study suggests the pivoted IDF weighting method for better retrieval effectiveness, on the assumption that medium frequency terms are more important than low frequency terms. We thoroughly evaluated this method on three test collections and it showed performance improvements especially at high ranks.

The present study has two main objectives. The first objective is to devise a new term weighting technique which can be used to weight the significance value of each word stem in a test collection of documents on the subject of "enteral hyperalimentation." The next objective is to evaluate retrieval performance of proposed term weighting technique, together with four other term weighting techniques, by conducting a set of experiments. The experimental results have shown that the performance of Sparck Jones's inverse document frequency weighting and the proposed term significance weighting techniques produced better recall and precision ratios than the other three complex weighting techniques.

The purpose of this research is to evaluate a short-term export demand forecasting model reflecting individual passenger vehicle brands and market characteristics by using Vector Autoregressive (VAR) models that are based on multivariate time-series model. The short-term export demand forecasting model was created by discerning theoretical potential factors that affect the short-term export demand of individual passenger vehicle brands. Quarterly short-term export demand forecasting model for two Korean small vehicle brands (Accent and Avante) were created by using VAR model. Predictive value at t+1 quarter calculated with the forecasting models for each passenger vehicle brand and the actual amount of sales were compared and evaluated by altering subject period by one quarter. As a result, RMSE % of Accent and Avante was 4.3% and 20.0% respectively. They amount to 3.9 days for Accent and 18.4 days for Avante when calculated per daily sales amount. This shows that the short-term export demand forecasting model of this research is highly usable in terms of prediction and consistency.

The Academic library services are based on specialized subject resources in academic fields in order to maximize the desirable direction of its services. Accordingly, there are some academic libraries introduced and applied subject specialist librarians. However, they can not objectively analyze the strengths and weaknesses as well as future directions to subject specialized service. The purpose of this study examined three library cases which the structure of organized subject specialist librarian. It tried to give a set of effective guidelines for academic libraries to introduce subject specialist librarian. Analysis showed that the initial problems of subject specialist librarians in its early stages are appeared: carrying out the role, appraisal-results in human resource decision making such as rewards and promotion. In order to successful introduction of subject specialist librarian in academic library, there are solutions that solving the problems which happen in early stage, active guidance and public relations strategy for faculty, approaching to activate integration within its library and cooperating among academic libraries should be back up for improving effectiveness in the long term.

We investigated dietary effects of green tea powder (GTP) on plasma lipids, platelet aggregation, hemolysis, plasma TBARS, and liver enzymes. Thirty one volunteer diving women living on Jeju island consumed 4 g green tea powder daily for a period of four weeks and data for the study subjects were analyzed on the basis of diagnostic criteria for blood pressure (BP)(${\geq}$ 140/90 mmHg), plasma total cholesterol (TC)(${\geq}$ 200 mg/dL), and triglyceride (TG)(${\geq}$ 150mg/dL). Subjects with high BP had significantly higher TC and TG than those with normal BP. Subjects with higher TC had higher TG, and those with higher TG had lower HDL cholesterol. Platelet aggregation in the initial slope was significantly higher in subjects with normal BP, normal TC, or normal TG than their counterparts in high BP, TC, and TG. HDL cholesterol after GTP intake increased only in subject groups with normal BP, normal TC, or normal TG, and plasma TG after GTP intake decreased only in groups with higher BP, higher TG, or higher TC. Plasma TC and TG in subjects with normal BP increased after GTP intake. GTP intake caused a decrease in the initial slope of platelet aggregation in all subject groups with little effect on maximum aggregation. Total bilirubin showed a significant increase and GOT increased in all subject groups after GTP intake. Beneficial effects of short term intake of green tea powder might differ depending on the subject conditions in terms of blood pressure, plasma lipids, and other cardiovascular conditions. However, with the hypolipidemic, antithrombotic, and antioxidant actions of its bioactive flavonoids, long term usage of GTP or brewed green tea may provide preventive effects against cardiovascular disease.
