The Purpose of this paper is to analysis on consumer's purchasing behavior and intention of local food. To analysis consumer's purchasing behavior, a series of homemaker surveys were conducted. The sample size of the survey is 416 respectively. As a survey result, consumer's purchasing behavior shows that purchasing ratio of local food and buying place is various type. By decision tree model analysis showed that consumer's purchasing intention is enough to establishing local food system in region. Therefore, strategies for regional consumption are needed expression of the place city and county of origin, diversification of purchasing item and buying area, and sustainable improvement for safety and trust on local food.

This paper proposes a curtailed-sequential probability ratio test (SPRT) control chart. For using the conventional SPRT control chart, the number of items inspected in a sampling point should have no restriction since items in a sampling point are inspected one by one until an SPRT Is terminated. The number of observations taken in a sampling point, however, has an upper bound since sampling and testing of an item is time-consuming or expensive. When the sample size reaches the upper bound without evidence of an in-control or out-of-control state of a process, the proposed chart makes a decision using the sample mean of all observations taken in a sampling point. The properties of the Proposed chart are obtained by a Markov chain approach and the performance of the chart is compared with fixed sample size (FSS) and variable sample size (VSS) control charts. A comparative study shows that the proposed chart performs better than VSS control charts as well as conventional FSS control charts.

The purpose of this paper is to show that lexical equivalency in translation can be achieved when it is based on semantic prosodies of lexical items. This paper examines the semantic prosodies of two seemingly synonymous English adjectives ‘empty’ and ‘blank’ on the basis of the corpus given in Cobuild English Collocations on CD-ROM and proposes that they are different in terms of spatial dimensions. Thus when a Korean equivalent pin derived from the verb pita is translated into English, syntagmatic phraseological environments of the Korean adjective must be taken into account to attain the equivalency of the source and target languages. Relevant Korean corpus was taken from the 21st Century Sejong Plan (2002). Out of 12 examples of pin konggan, five appear to be equivalent to ‘blank’ and seven to ‘empty.’ The five to seven ratio in different usage indicates that the equivalency problem concerning the lexical item pin is not a trivial matter in translation.

Objectives : Based on the analysis of Yin-Yang[음양] characteristics and symptoms, each person is classified into Yin-Yang. Also the validity of the result is statistically analized. Methods : From Feb. to May. 2003, the data were collected through a questionnaire given to 690 patients. The questionnaire was composed of 34 items which were about personality, habit, sweat, response to coldness, thirst, bowel, urine, physical shape, and menstruation for women only. SD(Semantic Differential Technique) used for each item, each item is measured as a contrast of two opposite symptoms. Reliability analysis was used to select items and categories. Based on means of items in each category the Yin-Yang index was developed. The validity of Yin-Yang index was investigated using classification and clustering analysis. In statistical analysis, SPSS V10.0.7 PC was used. Results : The obtained results are summarized as follows: 1) We constructed Yin-Yang index based on the middle point of the sum of categorical means. Then we classified each person into Yin or Yang. 2) To investigate the validity of the distribution of personal Yin-Yang degree, the crosstabulation of results from clustering and classification was used. The hit ratio for classification was much higher than Maximum Chance Criterion($C_{max}$), and concurrence in crosstabulation was successful. Therefore we can infer that the distribution of Yin-Yang was valid. Conclusions : Based on Yin-Yang characteristics and symptoms, we was analyzed personal degree of Yin-Yang, and confirmed the validity of its distribution. Therefore this index can be used further for Bian-Zheng [변증] and classification of the constitution.

The purpose of this study was to develop and validate a competency tool for new nurses and to pilot-test it with new nurses. A Delphi survey was conducted to develop a competency tool, and a self-evaluation was conducted among new nurses who pilot-tested the finally derived competencies. The Delphi survey panel consisted of 18 people, including adjunct professors at the College of Nursing, nursing managers, and nurses with master's degrees. The Delphi survey asked about the validity of the competencies constructed in two rounds. After analyzing the Delphi results with mean, standard deviation, content validity ratio, degrees of convergence, and degrees of consensus, 12 core competencies and 36 enabling competencies were finally derived. The competencies consisted of clinical judgment and management (nine items), task competence (four items), patient orientation (five items), moral value orientation (three items), cooperation (two items), supply management (two items), professional development (three items), confidence (one item), self-control (two items), flexibility (two items), influence (one item), and nurturing others (two items). The finally derived competencies were pilot-tested with 229 new nurses who had worked for 2-12 months. The self-evaluation scores of new nurses were distributed differently according to their working period. In this study, the competencies required for new nurses were identified and the corresponding enabling competencies were identified. In the future, it is expected that a competency-based education program will be prepared based on these findings, and furthermore, it will be possible to provide high-quality medical and nursing services that meet patients' needs by improving the competency of new nurses and lowering the turnover rate.

This study is about the description method & scope of maintenability in window components which have been applied to the remodelling work in Apartment Housing. Already we did established the maintenability performance index through the preceding research in recent. It is defined as changeability, prefabrication, coordination. and capacity of performance preservation. As the results of analysys on the performance information that is reported by catalog & internet media, the ratio of adaptation as a maintenabilty performance was revealed to percentage of 11(11%). And as the respects of represented content, majority of the performance information only have dealt with advertising-effect, rather than physical performance make easy to change and separat.

In this paper, the unit processes in the typical water treatment plant, which need to be expanded because the water demand is over the existing water treatment capacity in the near future, were carefully examined to upgrade the water treatment plant. The models were installed in the fields as a distorted model based upon the hydraulic similitudes. The models having the constant discharge ratio in the unit processes between the model and the prototype were installed as two units to compare the treatment efficiencies. The capacity of the individual unit, which is a model of the prototype of $250,000m^3/day$ capacity, was $24m^3/day$. In the mixing and flocculation experiments, the mixing intensity of flocculators G was selected as the main experimental item. The optimal mixing intensities G, which are 65/sec for experimental discharge of $1m^3/hr$ and 85/sec for experimental discharge of $1.3m^3/hr$, are identified based upon the comparison the relative turbidity removal efficiencies. Also, the outlet weir loading was selected as the main experimental item in the sedimentation process. Through the continuous experiments with the main experimental items of the mixing intensity of flocculators G and the outlet loading of the weir in the sedimentation basin, about 20% upgrading compared to the existing water treatment capacity was obtained.

This study was conducted to investigate practice rate of dental hygiene assessment and to understand the performance ratio according to hospital type. A questionnaire survey was conducted on 195 dental hygienists, and the dental hygiene assessment items examined were 6 types of dental history, medical history, vital signs measurement, extraoral examination, intraoral soft tissue examination, andtissue examination. As a result of the study, the item with the highest percentage of performers was 92.8% of dental history, and the lowest item was extraoral examination 57.9%. And, dental clinics were higher than dental hospitals and university hospitals in all dental hygiene assessment categories, and in particular, performance rates of extraoral examination and intraoral soft tissue examination were higher in dental clinics. Considering the overall high rate of dental hygiene assessment through this study, it is necessary to discuss the legal work of dental hygienists and to reflect the insurance fee.

Index adjusted ration method has been widely utilized in public construction secter for contract sum adjustment by price fluctuation. In this method. the Production Price Index are used for calculating the base ratio. but the PPI can't reflect the property of construction project in respect of the selected item and weight structure. In this research we prove the problem of using the index adjusted ration method in contract sum adjustment by price fluctuation. and improve it by using the construction cost index. which has the property of construction project. And the result. we figure out the difference between the PPI and CCI by $6.7\%$ in maximum value.

We propose a hybrid broadcast scheduling based on a combination of periodic and on-demand data scheduling methods for mobile data broadcasting in convergence networks from communication and broadcasting. We consider an environment in which the forward channel is for data broadcasting and the reverse channel is for sending data requests via cellular phones, WLAN, WiBro, etc. Collecting statistics of requests from clients, the server partitions the data items into hot-item and cold-item sets. Hot items are sent based on a push-based scheduling. An on-demand scheduling method is applied to cold items. Performance evaluation from simulations shows that our proposed scheduling algorithm yields small response time with high successful response ratio.
