This study aims to examine the correlations between undergraduates' major-interest congruence and stress coping behaviors and major adjustment. And in order to find there is any group violating Holland's congruence hypothesis, this paper divides them into four groups according to the degree of major-interest congruence and major adjustment. Also, it examines the difference of stress coping behaviors among the four groups. The followings are the chief results of this paper. First, according to the result of analyzing the effects of major-interest congruence and stress coping behaviors on major adjustment, congruence did not affect major adjustment significantly. Second, according to the result of dividing them into four groups by the degree of major-interest congruence and major adjustment, there is one group with high congruence but low major adjustment and also a group with low congruence but high major adjustment. Third, according to the result of examining the difference of stress coping behaviors among the four groups by the degree of major-interest congruence and major adjustment, there is significant difference among the four groups. Above results imply that in major adjustment, we should consider factors other than major-interest congruence, and stress coping behaviors are particularly important for it. Therefore, it is necessary to train their stress coping behaviors and also develop programs to facilitate major adjustment. Also, it implies that in the use of Holland's theory, it is crucial to use it based on the client's various information and uniqueness rather than to apply it in a conventional or unconditional way.
This study investigated the specific effects of dance themed movies on dance students in their passion for dance and affect. The related data is generated by choosing a method of Convenience Sampling and used a sample of 112 dance students in high school of arts which located in Seongnam-si, South Korea. The dance students divided into 3 group of school year and also 2 group of gender. The dance themed movies which are used in this research are First Position, Billy Elliot and Mao's Last Dancer. Also, the dance students were asked to answer the survey which are based on the Self-administration. In order to obtain several findings below, Frequency analysis, Exploratory factor analysis, Reliability analysis, t-test, ANOVA, Correlation analysis and Linear structural relation model were applied to the gathered data using statistics utility SAS 9.4. First, there was a significant difference between the school years in the passion for dance and affect of students after watching movies. Second, there was a significant difference in students' affect depended on their majors (dance major is divided into three specialized major which are ballet, korean dance and modern dance). Third, there was a significant difference in the passion for dance and students' affect which is irreverent to their dance career (such as years they have learned dance). Forth, there was a significant difference in the passion for dance and negative affect of 'dance' students after watching movies. To summarize, the findings demonstrate that there is a partial difference, specially significant effects on their negative affect in the dance passion and affect of dance students depended on their characteristics after watching dance themed movies.
The purpose of this study was to develop and validate tool for measuring the communication skills of dental hygienist. The survey was modified and revised to fit into Korean culture. Also the reliability and validity was tested in order to ensure the survey was properly evaluating communication skills of dental hygienists. A survey was conducted with outpatients in dental clinics located in Seoul, Gyeonggi, and Daejeon area. The 483 answers out of the total collected answers were used for the final analysis of the study, using PASW Statistics 18.0 and IBM SPSS AMOS 7.0 to measure the validity and reliability. The factor analysis showed that the communication skill of the dental hygienists was composed of three elements, namely 'being caring and respectful' communications, 'sharing information' communications and 'tending to comfort' communications to reduce pain and anxiety. The validity of the model examined by a confirmatory factor analysis satisfied most of the relevant requirements. All of the factors had the conceptual reliability and variant extracted index above the minimum requirements, ensuring reliability and concentrated validity. Also, the value of the square of the correlations between all latent factors which was larger than the square of the correlation between all of the factors, thus proving the discriment validity. Cronbach's ${\alpha}$ was 0.8, which shows high reliability level. In conclusion, it was proven that dental hygienist's communication skill measurement tool has high validity and reliability. Further, this study can be used to improve dental hygienists' communication skills. Therefore, this will improve oral health of clients and manage them.
Process monitoring technology is able to detect the faults and the process changes which occur in a process unpredictably, which makes it possible to find the reasons of the faults and get rid of them, resulting in a stable process operation, high-quality product. Statistical process monitoring method based on data set has a main merit to be a tool which can easily supervise a process with the statistics and can be used in the analysis of process data if a high quality of data is given. Because a real process has the inherent characteristics of nonlinearity, non-Gaussianity, multiple operation modes, sensor faults and process changes, however, the conventional multivariate statistical process monitoring method results in inefficient results, the degradation of the supervision performances, or often unreliable monitoring results. Because the conventional methods are not easy to properly supervise the process due to their disadvantages, several advanced monitoring methods are developed recently. This review introduces the theories and application results of several remarkable monitoring methods, which are a nonlinear monitoring with kernel principle component analysis (KPCA), an adaptive model for process change, a mixture model for multiple operation modes and a sensor fault detection and reconstruction, in order to tackle the weak points of the conventional methods.
With the increase of visitors to rural tourism villages, the direct selling at sites is getting vitalized. Accordingly, their display stores is getting more important. Therefore, this study has selected 30 domestic rural tourism villages as study objects for the attitude survey of 200 farming suppliers and the site examination for the designs of those display stores in order to analyze their status and classify the types of necessity. Such operation status as sale item, sale method, method of supply and demand, major customer, sales scale, manager, opening hour, and operation cost were examined, to identity and for design factors the pattern, material quality and color were investigated. For the attitude of farming suppliers, the tactics of sales, the reason for being positive or negative, the functionality and the features of display stores were examined through brainstorming. IBM SPSS Statistics 20 Program was employed for Frequency, which indicated that village chiefs and store managers with the sales scale of 1 to 20 million won are dealing with female customers in their 40's and 50's and that those stores are open at the time of experience or year round without any operation expense. Permanent type and Fixed type were found to be the design factors of the display-case type with the material and the color of wood and orange respectively. The result of investigation analysis of farming suppliers' attitude showed the followings: the need of display stores is quite high, structure type and permanent type have high fitness and from the viewpoint of display-on-table type as a standard moving type was very convenient. The analysis of significant items at the characteristics of those display stores revealed that their locations, quality conservation, sanitation, users' convenience, designs and promotion are very important. The result of status analysis revealed that though there is a correlation among the types of display stores depending on the visiting season of tourists their installing is not desirable. Three types have been analyzed: Type 1 is a structure type only in the villages with continuous visitors, Type 2 a moving-table type only in the villages with temporary visitors and Type 3 is a fixed display-case type.
Background: Today, tuberculosis continues as an important cause of death in Korea despite the effective treatment and prevention. So we have studied charicteristic distribution of death by pulmonary tuberculosis through epidemiologic survey. Subjects and Method: The mortality data were obtained from 684 pulmonary tuberculosis cases who died in a tuberculosis-centered hospital in Seoul during the period of 5 years from 1986 to 1990. In order to estimate the distribution of death by tuberculosis, t-test and $x^2$-text were performed on the data. Results: 1) 19.9% of patients died among the total 3,441 hospitalized pulmonary tuberculosis cases during 5 years. 2) In distribution of sex and age, male death occupies 81% of total death. Significantly high proportions of younger female death (under 40 years-old) were also observed. 3) In terms of medical security status, medical assistance group occupies 42.3% of medical insurance group while the non-security group also occupies 11.8% of total death. 4) Treatment interruption was observed in 78% of total death. Conclusion: Special attention should be given to the identification, management and follow up of high risk group in nationwide tuberculosis control program.
ANFIS-based methodology for improving GloSea5 ensemble weather forecast is developed and evaluated in this study. The proposed method consists of two steps: pre & post processing. For ensemble prediction of GloSea5, weights are assigned to the ensemble members based on Optimal Weighting Method (OWM) in the pre-processing. Then, the bias of the results of pre-processed is corrected based on Model Output Statistics (MOS) method in the post-processing. The watershed of the Chungju multi-purpose dam in South Korea is selected as a study area. The results of evaluation indicated that the pre-processing step (CASE1), the post-processing step (CASE2), pre & post processing step (CASE3) results were significantly improved than the original GloSea5 bias correction (BC_GS5). Correction performance is better the order of CASE3, CASE1, CASE2. Also, the accuracy of pre-processing was improved during the season with high variability of precipitation. The post-processing step reduced the error that could not be smoothed by pre-processing step. It could be concluded that this methodology improved the ability of GloSea5 ensemble weather forecast by using ANFIS, especially, for the summer season with high variability of precipitation when applied both pre- and post-processing steps.
The purposes of this study were to assess dental fear and anxiety level of patients attending a dental clinic using the dental fear survey (DFS) scale, to apply interventions chosen by patients for reducing dental fear and anxiety and measure their effects. This study surveyed 34 patients who visited a dental clinic in Seoul about their self-rated health and their experience of dental fear, and measured the level of dental fear using DFS. Trained dental hygienists applied interventions desired by the patients for reducing dental fear and anxiety and, for each intervention, examined the patients' satisfaction (very helpful [5 point]~not helpful at all [1 point]). Collected data were analyzed using IBM SPSS Statistics ver. 21.0 through independent t-test or one-way ANOVA for difference in level of fear according to related characteristics, and through Wilcoxon signed rank test for comparison between before and after the intervention. The subjects' mean level of fear (DFS score) was 44.53, which was an average level, and the level of dental fear was relatively high for stimulus-response (2.72). The level of dental fear was higher in those who had experienced pains or indirect dental fear from dental treatment in the past, and those whose subjectively perceived health state was poor (p<0.05). With regard to the applied dental fear intervention, 'Helpful (3.57)' was the most common answer. Overall satisfaction before and after the application of dental fear intervention was generally high as 4.37 and 4.35, respectively, but it decreased slightly after the intervention. In order to lower the level of dental fear, it is considered effective to survey not only the level of dental fear but also patients' need of dental fear interventions and to apply a suitable intervention. It is also required to educate dental workers and to develop related manuals.

Recently, demands with practical applications using high resolution imagery are increasing, according to addressing new sensor data. Since late 1990s, attempts for application to transportation problems of satellite imagery data have been intensively carried out in US, and these kinds of studies are being categorized into the name of RS-T(remote sensing in transportation). Further, this study is also linked with GIS-T(GIS for transportation), being in the matured stage, and then it contributes to wide uses of remotely sensed imagery. In this study, RS-T is briefly summarized. Later, in order to apply urban transportation analysis with satellite imagery as ancillary data, implementation, as prototyped extension program, for extraction of gravity-typed accessibility indices of transportation geography is performed in the ArcView-GIS environment. It is thought that applied results by two models among implemented models in this study can be utilized to characterize transportation accessibility in a region and to apply as useful statistics related to urban transportation status for regional transportation planning, if time series data are used.
The purpose of this study was to investigate job satisfaction of dental hygienist. A questionnaire survey was conducted on 224 dental hygienist. The 224 data were analyzed by descriptive statistics, ANONA, Pearson's correlation analysis, and multiple regression analysis with SPSS(Statistical Package for Social Science) Ver.19.0. The average score of the communication skill was $3.32{\pm}0.49$, interpersonal relationship ability was $3.45{\pm}0.48$, job satisfaction was $3.19{\pm}0.44$. The average score of the communication skill according to the general characteristics was the married was higher than the singles, the higher the career. The average score of the interpersonal relationship ability according to the general characteristics was the higher he education, the higher the income and the business management. The average score of the job satisfaction according to the general characteristics was the higher the business management. A multiple regression analysis was conducted to examine the effects of communication skill and interpersonal relationship ability on job satisfaction, which had the lower career(t=-2.846, p=0.005), high communication skill (t=2.099, p=0.037), high interpersonal relationship ability(t=4.142, p=0.000). In order to improve the job satisfaction of the dental hygienist, provide proper compensation and the effort to improve the communication skill and interpersonal relationship ability.
