The purpose of this study was to investigate determinants of stop smoking. The data on which the analysis was based come from a survey of 355 middle-aged men in Seoul. The data was analyzed using proportion, x²-test, Pearson's Correlation Coefficient and Stepwise Multiple Regression. The following were the results; 1. Success rate of stop smoking is 19.9% of 229 persons who attempted to quit smoking. 2. As for the number of quit attempts, 33.3% of ex-smokers tried once; 25.4% of current smokers tried twice. 3. As for methods of quit attempts ex-smokers showed higher tendency in using will power and books/guides than current smokers who in using will power alone. 4. For the attitudes on smoking of family, the majority of ex-smokers and current smokers were opposed absolutely. 5. The main opposite to smoking were wives in cases of both ex-smokers and current smokers, but More ex-smokers answered that the main opposite to smoking were others than current smokers. 6. As for the measures of smoking in the office, more ex-smokers answered inviting than current smokers and more current smokers assigned a smoking spot than ex-smokers. 7. Majority of ex-smokers approve of restriction at public spot strongly. 8. As for the attitude about caution on a cigarette case, more ex-smokers insisted than current smokers. 9. There was a relation between the degree of exposure about knowledge and the degree of knowledge. 10. Stepwise Multiple Regression portray that following factors influence stop smoking in order named. (1) attitude on the smoking restriction at public spot, (2) methods of quit attempt, (3) attitude about caution on cigarette case. Even so, it turned out that these factors alone can explain only 20% of self-examination. Therefore study for the other factors ought to be continued. I submit following suggestions ending this study. 1. Continuous study of the other factors affecting stop smoking must be carried on. 2. Since there was a relation the degree of exposure about knowledge and the degree of knowledge, efficient health education is required using campaign and mass media.

To improve the effectiveness and efficiency of public health personnel training, we evaluated not only how appropriate the students felt the objectives, contents, methods and multimedia used in the train ing courses, but also how much the students accomplished the objectives and applied skill and knowledge to their own works. We selected 5 courses for the study : Tuberculosis control, Radiological technique, Public health information, Immunization, Mental health management courses used by Kirkpatrick's evaluation model. Reaction evaluation was carried out in final day by questionnaire. The results showed that all of them were very satisfied with educational input and curricula, learn Ing environment. Secondly, we measured the degree of learning achievement on pre and post training by questionaire of specific behavioral objectives. The degree of learning achievement was statistically higher just after training than pre training (paired t-test, p<0.01). Thirdly, evaluation of behavioral change to job was conducted to find out how much students applied skill and knowledge to their own job in 3 months after training by questionnaire. The results of behavioral change evaluation showed that 43.5% of the students who were performing job related with the training courses in 3 months after training applied the learned skill and knowledge to their own job quite well and 37.8% of them applied relatively well, therefore total 81.4% of them applied to their own job. And effectiveness of training for the above mentioned students showed that 41.9 % of them had improved or enforced their jobs after training, 35.5% of them had had no remarkable changes, and 15.7% had newly applied the learned skill and knowledge to their jobs. For evaluating the degree of usefulness of material predistribution in two weeks before training, we compared experimental groups with control groups. The results showed that general reactions are helpful but the degree of learning achievement is no discrepancy.

Similarity searching is a basic issue in information processing because of the large size of formal contexts and their complicated derivation operators. Recently, some researchers have focused on knowledge reduction methods by using granular computing. In this process, suitable information granules are vital to characterizing the quantities of attributes and objects. To address this problem, a novel approach to obtain an entropy-weighted concept lattice with inclusion degree and similarity distance (ECLisd) has been proposed. The approach aims to compute the combined weights by merging the inclusion degree and entropy degree between two concepts. In addition, another method is utilized to measure the hierarchical distance by considering the different degrees of importance of each attribute. Finally, the rationality of the ECLisd is validated via a comparative analysis.

In organizations, evaluating the competency of individuals through the position or status has many limitations. To overcome these limitations, this study analyzes the organization's informal network using social network analysis. We measured out-degree centrality and in-degree centrality by making use of social network analysis technique. Out-degree centrality is interpreted as 'madangbal' in that actors actively help other people, while in-degree centrality is interpreted as 'prestige' in that other people want to have a relationship with. This research examines the effects of individual's 'prestige' and 'madangbal' in the instrumental network and communication network on IT competency. We carried out empirical analysis using social network data that were collected from undergraduate students. The result reveals that relationship between IT competency and centrality in the instrumental network is statistically significant, while relationship between IT competency and centrality in the communication network does not show significant results.

A knowledge-based system with fuzzy production rules is a representation of static knowledge of an expert. On the other hand, a real system such as the stock market is dynamic in nature. Therefore we need a strategy to reflect the dynamic nature of real system when we make inferences with a knowledge-based system. This paper proposes a strategy of dynamic inferencing for a knowledge-based system with fuzzy production rules. The strategy suggested in this paper applies weights of attributes of conditions of a rule in the knowledge-base. A degree of match(DM) between actual input information and a condition of a rule is represented by a value [0,1]. Weights of relative importance of attributes in a rule are obtained by AHP(Analytic Hierarcy Process) method. Then these weights are applied as exponents for the DM, and the DMs in a rule are combined, with MIN operator, into a single DM for the rule. In this way, overall DM for a rule changes depending on the importance of attributes of the rule. As a result, the dynamic nature of a real system can be incorporated in an inference with fuzzy production rules.

This research aimed to survey foodservice hygiene management practices performed by principals and teachers as well as examine foodservice employees' hygiene knowledge in kindergartens. Surveys were administered to principals, teachers, and foodservice employees at 392 kindergartens. The total average score of six categories was 4.28 out of 5.0. Average score of the production process management category was the lowest at 3.90 while safety management was the highest at 4.69. Other average scores were as follows: facilities and equipment 4.20, personal hygiene 4.14, food ingredient control 4.35, and environmental sanitation 4.39. Teachers' foodservice hygiene management practices scored 3.8 points out of 5 on average. Hygiene knowledge of foodservice employees was also tested. The mean score of foodservice hygiene knowledge was 76.29%. The lowest scoring category was personal hygiene, suggesting that foodservice employees require more knowledge on proper personal hygiene practices. Possession rates of dish sterilizer, ultraviolet sterilizer, and hand washing facilities in the kitchen were low. These equipment installation rates should be raised accordingly. To enhance control of foodservice hygiene, kindergarten management should pay more attention to education and training related to foodservice sanitation.

The purpose of this study was to identify the effect of structured information provided on knowledge and self-care behavior. The subjects of this study were both hospitalized patients and outpatients in K university hospital. The instrument use for this study were the knowledge assessment tool and self-care behavior assessment tool by Eom Soon-Ja(1998) and they were modified for liver cirrhosis patients. The data were analyzed by t-test, Chi-square test, Pearson correlation coefficients using SAS program. The results of this study were as follows. The experimental group which had received structured information provided showed greater increased knowledge of liver cirrhosis(P=.001). The experimental group which had received the structured information provided indicated increased self-care performance rate, especially after information about diet(P=.001), activity and bed rest(P=.001), drug therapy and visiting the hospital(P=.001), prevention of a complication and observation(P=.001). In conclusion, structured information provided showed increased in the degree of knowledge and self-care behavior, so information showing is an effective nursing intervention. It is much needed to employ information showing for chronic patients.
