Purpose : The purpose of this study was to identify the self-efficacy, major satisfaction, and degree of adjustment to college life of nursing students and the relationships among the foregoing. Methods : This study was conducted with 319 nursing students in B city from May to June 2019. The collected data were analyzed with frequency, percentage, mean and standard deviation, t-test, ANOVA, Scheffe's test, and Pearson Correlation Coefficient using the SPSS /WIN 22.0 program. Results : The self-efficacy score of nursing college students was shown to be 2.95±0.32 points, major satisfaction score was shown to be 3.83±0.55 points, and college adjustment score was shown to be 3.52±0.55 points. The degrees of adjustment to college life were significantly different according to general characteristics of nursing students as follows; grade (F=6.614, p=.000), health condition (F=13.384, p=.000), club activities (t=4.557, p=.000), happiness index (F=32.094, p=.000), part-time job (t=2.781, p=.006), and motive of major selection (F=7.300, p=.000). The adjustment to college life of nursing students showed a weak negative correlation with self-efficacy (r=-.196, p<.001) and a strong positive correlation with major satisfaction (r=.782, p<.001). Major satisfaction and self-efficacy showed a weak negative correlation (r=-.185, p<.001). Conclusion : Through the results of this study, it can be seen that repetitive studies are necessary in relation to the self-efficacy, major satisfaction, and college adjustment of nursing students, and that interest in effort for the development of programs that can improve nursing students' major satisfaction and college adjustment are necessary.

Purpose : The purpose of this study was to identify the degree of occupational therapist's sleep quality and examine the correlation between sleep quality and job stress. We also investigated the effects of the occupational therapist's sleep quality on job stress. Therefore, we aimed to investigate the importance of sleep quality and find a way to reduce job stress in occupational therapists. Methods : We conducted a study from November 7 to from December 23, 2022. To assess sleep quality and job stress, sleep quality of scale and Korean occupational stress scale-SF (KOSS-SF) were used. The general characteristics, sleep quality, job stress were examined using a frequency analysis and presented with descriptive statistics. The pearson correlation coefficient was used to determine, whether there was a correlation between sleep quality and job stress. To find what factors have and effect on job stress, we conducted a multiple regression analysis. A significance level of α=.05 was used to verify statistical significance. Results : First, average sleep quality score was 2.10±.19. Second, a significant correlation was found between sleep quality and job stress (p<.01). And As a result of the relationship between sleep quality sub-factors and job stress, day time dysfunction (r=.23, p<.01), restoration (r=.18, p<.05), difficulty of falling asleep (r=.38, p<.01). difficulty of awakening (r=.36, p<.01), satisfaction (r=.33, p<.01) and difficulty of maintaining sleep (r=.24, p<.05) showed a statistically significant relationship with job stress. Third, the sub-factors of sleep quality influencing job stress were difficulty of falling asleep (β =.26, p<.01), difficulty of awakening (β=.23, p<.01) and satisfaction (β=.21, p<.01). Conclusion : The results of this study, demonstrated the importance of sleep quality in affecting job stress.

The purpose of this study was to investigate the impact of depression, discomfort, spirituality, physical care, and opioid use on pain with terminally ill cancer patients residing in hospice units. The convenient sample of this study consisted of 41 terminally ill cancer patients at three hospice units in university affiliated hospitals. Patients were interviewed with structured questionnaires three times at predetermined intervals: admission to the hospice unit (Time 1), one week later (Time 2), and two weeks later (Time 3). The data was collected from January 1998 to January 1999 and was analyzed using ANOVA, Pearson correlation coefficient, and multivariate multiple regression. 1. The mean age of the participants was approximately 55 years old. In terms of diagnosis, lung cancer showed the highest frequency (19.5%), followed by stomach cancer and rectal cancer (17.1%). The motive of seeking hospice unit admission was control (72. 2%), followed by spiritual care (50%), and symptom relief (38.9%). 2. Regarding the type of pain felt, the highest pain frequency the participants experienced was deep pain (55%), followed by multiple pain (25%), intestinal pain (10%), then superficial (5%) and neurogenic pain (5%). For the level of pain measured by VAS, there was no significant difference among the three time points; Time 1 (5.04$\pm$2.21), Time 2 (4.82$\pm$2.58) and Time 3(4.73$\pm$2.51). 3. There was significant change seen in spirituality and physical care in each time interval. Namely, the longer the length of admission at the hospice unit, the higher the importance of spirituality (p=0.0001) and the more the physical care the participants received (p=0.01). The opioid use at the three time points showed the following frequencies : Time 1 (75.6%), Time 2 (85.4%) and Time 3 (75.6%). 4. Regarding factors influencing pain, the pain level was significantly affected by the depression level (p〈0.01) and the opioid use (p〈0.1). These results were the most significant at the two time points (Time 1 and Time 2). At Time 3 (two weeks later), the pain level was significantly affected by the depression level (p〈0.05) and the amount of physical care the participants received (p〈0.1). In conclusion, the terminally ill cancer patients had moderate pain, were generally depressed, and were treated with opioid analgesics. As approaching death, the patients received more physical care due to increased physical symptoms experienced and they had a higher perception of the importance of spirituality. Thus, health care professionals need to provide continuous care for each of them to die comfortably physically, psycho- logically, and spiritually.

A proto-type seismic measurement system with a reference was developed to improve S/N (signal-to-noise ratio) of seismic data, especially in noisy urban areas. Two pairs of correlation measurements (the one for microphone and geophone, and another for electromagnetic (EM) loop and geophone) were carried out near Kimpo Airport and at Kimje. The spectrum analyses were also performed to investigate the correlation of two pairs of time series; one for microphone and geophone, and another for EM loop and geophone. The sound waves measured with the microphone and the geophone are highly correlated. However, differences in the reponses are readily identifiable across 200 Hz; in the vicinity of 100 Hz, the spectral energy for geophone is 20 dB higher than that for microphone, and at near 500 Hz, the spectral energy for microphone is 30 dB higher than that for geophone. Overall, the spectral energy appears concentrated on the frequency window below 600 Hz for geophone. It contrasts with the observation of dominant frequency at the range of above 200 Hz for microphone. The wave forms of EM noise (due to an ACDC inverter) measured with EM loop and geophone are consistently and highly correlated each other. The power spectrum of the EM noise for EM loop shows that the spectral energies at odd harmonic frequencies of 60 Hz are higher than those at even harmonic frequencies of 60 Hz. It is compared to the power spectrum for geophone; the spectral energies at odd harmonics are nearly same as those at even harmonic frequencies.

OFDM(orthogonal frequency division multiplexing) communications system is very attractive for the high data rate transmission in the frequency selective lading channel. Since OFDM has high PAPR(peak-to-average power ratio), OFDM signal may be distorted by the nonlinear HPA(high power amplifier). In this paper, we propose the DSI(dummy sequence insertion) method for OFDM communication system. Some sub-carriers are inserted for PAPR reduction. They carry the specified dummy data sequence which are used for only PAPR reduction and do not work as side information like the conventional PTS(partial transmit sequence) or SLM(selected mapping) method. We use the complementary sequence and the combination of the correlation sequence as the dummy sequence. Flipping technique is used for the DSI method to get the effective PAPR reduction. It is important that BER of the proposed method is independent of the damage of the dummy data sequence. And DSI method has better spectral efficiency than the conventional block coding. On the other hand, threshold PAPR method is applied to cut down the processing time. However, this DSI method is not better than the conventional PTS method in the respect of the PAPR reduction performance. The DSI method includes the threshold PAPR lower than the PAPR of the OFDM signal, reduces the processing time and improves the BER performance.

In order to investigate correlation between mother's dental ca re for her children and their dental caries, this study was conducted wi th the dental examination record of 365 children who showed the same number of questionnaires with those examined for dental conditions and questionnaires written by mothers among children between three and six years of age and their mothers in Yeoncheon, Gyeonggi province in June 2004 to estimate frequency and percentage of general properties of subjects and mother's oral health care behaviors for her children by research items, to carry out cross-tabulation analysis and correlation analysis following Chi-square distribution for the presence of dental caries in deciduous teeth and oral health care behaviors, and to use decision tree analysis among data mining techniques for those factors associated with the presence of dental caries in deciduous teeth, and drew the following conclusions. 1. For mother's oral health care behaviors and attitudes for her children, 225 mothers(61.6%) confirmed their children's teeth-brushing; 278(76.2%) used no fluorine; and 286(78.6%) observed their children's teeth, 322 mothers(88.2%) instructed their children in teeth-brushing while 268 (73.4%) provided dental care, 232 mothers(63.7%) treated their children's cavity; 290(79.4%) believed that their children had good dental conditions; and 294(80.5%) answered that they began to provide their children with dental care in deciduous teeth. 2. As for the presence of dental caries in deciduous teeth and dental health care behaviors, there were statistically significant differences in employment, confirmation after teeth-brushing, teeth observation, instruction in time for teeth-brushing, use of fluorine, cavity treatment, time for dental care, and perception of dental conditions(p<0.05). 3. As for correlation between dental caries in deciduous teeth and oral health care behaviors, mothers who worked, who believed that their children didn't have good dental condition, and who thought that it was necessary to begin to provide dental care in permanent teeth were found to get their children to suffer from dental caries in deciduous teeth. Besides, those who failed to confirm teeth-brushing, who used no fluorine, and who failed to observe teeth and gave no instruction in time for teeth-brushing were shown to get their children to suffer from dental caries in deciduous teeth. 4. Variables to determine the presence of dental caries in deciduous teeth were classified by cavity treatment, mother's employment, time for dental care, and observation of children's teeth. The first node to determine the presence of dental caries in deciduous teeth was found to be cavity treatment; the next criteria for classification after cavity treatment were shown to be mother's employment and time for dental care. In case of children with no cavity, they were found to be mother's employment and teeth observation.

This paper proposed a evaluation method for individual's subjective preferred location using EEG and emotional assessment. Visual stimulus were sequentially presented a total six points(the top and the bottom of the left, the top and the bottom of the center and the top and the bottom of the right on the screen). EEG were measured from twenty subjects according to each six points. At the same time, we were executed evaluation of subjects preferred location from emotional assessment. Alpha and beta wave were measured in Fp1, Fp2, F7 and F8 location, followed by ten to twenty electrode system. Correlations and variations of alpha and beta wave from each channel were calculated and analyzed. Because of the number of subjects population under 30, we used Speareman test for a correlation analysis between alpha and beta wave. Also, emotional assessments which compose of visual sense harmony, visual sense stability, stability of position and the visibility were performed and were analyzed by average and frequency. After visual stimulus, emotional assessments were performed. From the variance analysis of EEG, beta wave from F7 was appeared statistically significant as significance probability of 0.006. Also, between alpha wave and beta wave appeared a negative correlation(r=-0.190). From the post-hoc test of F7 beta wave, location 1, 5 and 6 appeared to difference statistically significant. Emotional assessment result according to six positions showed 0.00 significance probability. Thus, location and emotional assessment appeared to influence on each other. From the average and frequency analysis of emotional assessment, location 2 showed obtained of best emotional assessment score and appeared lower beta wave than other locations. Finally, most subjects showed a preference for location 2. Through obtained results in this paper, will be helpful to about human emotional assessment and EEG research.
