A new technique for land cover classification which applies digital image pre-classified by unsupervised classification technique, clustering, to Canonical Correlation Analysis(CCA) was proposed in this paper. Compared with maximum likelihood classification, the proposed technique had a good flexibility in selecting training areas. This implies that any selected position of training areas has few effects on classification results. Land cover of each cluster designated by CCA after clustering is able to be used as prior information for maximum likelihood classification. In case that the same training areas are used, accuracy of classification using Canonical Correlation Analysis after cluster analysis is better than that of maximum likelihood classification. Therefore, a new technique proposed in this study will be able to be put to practical use. Moreover this will play an important role in the construction of GIS database

The purpose of this study was to analyze the correlation between psychosocial factors and therapeutic flow in stroke patients and identify the factors influencing therapeutic flow. Total 168 stroke patients from 15 hospitals were measure for depression, stress, self-efficacy, rehabilitation motivation and therapeutic flow. Factors that affect the therapeutic flow correlation as s result of negatively correlated with depression(r=-.349, p<.001), stress(r=-.290, p<.001), self-efficacy(r=.528, p<.001), rehabilitation motivation(r=.186, p<.05) was found in the positively correlated. Finally the effect on therapeutic flow in stroke patients variables affecting self-efficacy(${\beta}=.443$, p<.001) and depression(${\beta}=-.155$, p<.05) were the order of analysis. These result demonstrate that the therapeutic flow of storke patients was a significant correlation on psychosocial factors, future study will continue to be needed.

The purpose of this study was empirically to reveal the structure relationship between ethical management of ski resort employee, organizational identification and customer orientation. For the research, survey of 200 people working in domestic ski resorts was conducted. The survey was composed of three variables(ethical management, organizational identification and customer orientation). The following results were obtained by confirmatory analysis, reliability analysis, correlation analysis and structural equation model analysis. First, ski resort employee's ethical management had a positive correlation with organizational identification. Second, ski resort employee's ethical management had a positive correlation with customer orientation. Third, ski resort employee's organizational identification had a positive correlation with customer orientation. This study suggested that the ethical management of ski resorts had positive effects on the attitudes and behaviors of the employees who regarded the organization as a common fate and provided high quality service considering the customer's position.

The purpose of this study was to investigate the factors affecting quality of sleep among middle-aged male workers. The participants of this study were 127 middle-aged male workers working in Jeonnam region, and the data were collected through self-reported structured questionnaire. Descriptive statics, t-test, one-way ANOVA, Pearson correlation coefficient and step wise multiple regression with SPSS/WIN 18.0 were used to analyze the data. According to the results, among the variables related to sleep quality, job stress showed a positive correlation, and job satisfaction showed a negative correlation. In addition, the factors such as job demands, occupational climate, job itself explained the quality of sleep at 24.5%. Based on the findings from the study, in order to improve the quality of sleep program for middle-aged male workers should be combined both strategies to increase job satisfaction and to decrease job stress. It is believed that the effort to reduce the amount of work needed to improve the quality of sleep will be necessary and the efforts among members of the organization will be necessary to establish a healthy workplace.

The purpose of this study was to investigate Stress Coping Type, Professor-student Interaction, Major Satisfaction on Life Stress of Nursing Students. The data were collected using questionnaire from 146 nursing students, May 27 to May 30, 2018 at a college in the J city. The analysis of the data was done through SPSS 20.0/window statistical analysis by descriptive statistics, t-test, ANOVA, Pearson's correlation, and multiple regression. Upon examining the correlation between Life Stress and Professor-student Interaction, Major Satisfaction the correlation was significant. The result of the multiple regression indicates the Professor-student Interaction(β=-.34, p<.001) predict 29.5%(F=9.70, p<.001). Based on the results of the study, it is expected to be used as basic data for various programs to improve professor - student interaction of nursing students.

In this paper, we propose simple combining schemes for sensing ATSC digital television signals with spectral correlation density (SCD). The detection algorithms exploiting the cyclostationarity exhibited by the pilot of ATSC digital television signals usually use the SCD value at a given particular frequency. However, we found that non-zero SCDs are found to be distributed over a certain range of frequencies in multipath fading environment. To utilize a set of non-zero SCD values computed in the vicinity of the pilot location, we formulate a class of combining methods in analogy with the maximal ratio combining, the square law combining and the equal gain combining. We show that the proposed simple combining schemes improve the detection performance by 0.5~1.0dB under multipath fading environments.

This thesis analyzed the intermediation and correlation of positive humor style and negative humor style through an entertainment program broadcasted on SBS. For the theoretical background, the Humor Style Questionnaire(HSQ) developed by Martin et al., was selected. As the research methods, first, after classifying the types of humor style of members of , this study analyzed how the positive humor style and negative humor style would intermediate the formation of humor, and also the correlation of humor style of members. The types of positive humor style and negative humor style shown in were balanced in 4:4, which was classified in accordance with age, career experience, and power. The mediation of humor formation occurred at the point where humors confronted. The humor style had the correlation with twist.

Objectives: This study aims to research correlation of the malondialdehyde level in urinalysis with cold hypersensitivity. Methods: We studied 128 patients visiting ${\bigcirc}{\bigcirc}$ Korean Hospital from March, 2013 to May, 2013. The subjects were categorized into two groups: cold hypersensitivity group (n=46) and control group (n=79). Patients in cold hypersensitivity group had been stressed because of severe cold hypersensitivity. First, We investigated the difference of the level of malondialdehyde between two groups. In addition, temperature of the two points, ST32 and LR3, was measured by using Digital Infrared Thermal Imaging (DITI) to find out whether the extent of cold hypersensitivity is related to the level of malondialdehyde. Results: There is no different characteristics between two groups. The average of malondialdehyde in cold hypersensitivity group ($1613.15{\pm}1260.71$) is significantly higher than in control group ($1170.01{\pm}1015.66$)(p=0.04). But there is no correlation between level of malondialdehyde and the extent of cold hypersensitivity (r=-0.22, p=0.13). Conclusions: Although the level of malondialdehyde in cold hypersensitivity group is higher than in control group, there is no significant correlation between level of malondialdehyde and the extent of cold hypersensitivity.

The purpose of this study was to identify to identify the relationship between knowledge of the SBAR(Situation-Background-Assessment-Recommendation) Attitudes towards SBAR and critical thinking disposition of nursing students. Subjects were 101 associate nursing students associate nursing students(3rd). The data were collected using self -report questionnaire from August 31 to October 26, 2018. Data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation using SPSS Win 23. The score for knowledge of the SBAR was 3.26, Attitudes towards SBAR scoring 3.31, Critical thinking disposition scoring 3.50. Knowledge of the SBAR(r=.46, p<.001) and Attitudes towards SBAR(r=.23, p=.023) were significantly positive correlation with critical thinking disposition in nursing students. Therefore, to increase the critical thinking disposition of nursing students, It is necessary to develop the program for increase knowledge of the SBAR and attitudes towards SBAR of nursing students.
