This study was a descriptive survey study to confirm the correlation between self-differentiation, Nursing Professionalism, and care efficacy in nursing college students, and to confirm the mediating effect of Nursing Professionalism in the relationship between self-differentiation and care efficacy. The data collection period is from October 30 to November 30, 2022. Data analysis was performed using t-test, Pearson's correlation, and regression methods. Studies have shown that the general characteristics that show significant differences in care efficacy were grade level and major satisfaction. The three variables were statically correlated. In the relationship between self-differentiation and care efficacy, Nursing Professionalism appeared to be a partial mediator (Z=2.196, p<0.05). The partial mediated effect explanatory power was 40%. This study was significant in that it examines the partial mediating effect of Nursing Professionalism in the relationship between self-differentiation and care efficacy for nursing college students, and has prepared the basic data for improving the care efficacy of nursing college students in the future. In the follow-up study, it would be created a program to improve the efficacy of care based on the results of this study and propose an analysis study of its effectiveness. It also proposes a study to expand the number of subjects to identify factors that can affect the efficacy of care.

The aim of this study was to clarify the impacts of acquisition parameters on artifacts in four-dimensional computed tomography (4D CT) images, such as the partial volume effect (PVE), partial projection effect (PPE), and mis-matching of initial motion phases between adjacent beds (MMimph) in cine mode scanning. A thoracic phantom and two cylindrical phantoms (2 cm diameter and heights of 0.5 cm for No.1 and 10 cm for No.2) were scanned using 4D CT. For the thoracic phantom, acquisition was started automatically in the first scan with 5 sec and 8 sec of gantry rotation, thereby allowing a different phase at the initial projection of each bed. In the second scan, the initial projection at each bed was manually synchronized with the inhalation phase to minimize the MMimph. The third scan was intentionally un-synchronized with the inhalation phase. In the cylindrical phantom scan, one bed (2 cm) and three beds (6 cm) were used for 2 and 6 sec motion periods. Measured target volume to true volume ratios (MsTrueV) were computed. The relationships among MMimph, MsTrueV, and velocity were investigated. In the thoracic phantom, shorter gantry rotation provided more precise volume and was highly correlated with velocity when MMimph was minimal. MMimph reduced the correlation. For moving cylinder No. 1, MsTrueV was correlated with velocity, but the larger MMimph for 2 sec of motion removed the correlation. The volume of No. 2 was similar to the static volume due to the small PVE, PPE, and MMimph. Smaller target velocity and faster gantry rotation resulted in a more accurate volume description. The MMimph was the main parameter weakening the correlation between MsTrueV and velocity. Without reducing the MMimph, controlling target velocity and gantry rotation will not guarantee accurate image presentation given current 4D CT technology.

The error rate equation of FH/MFSK signal of repeated diversity received over m-distribution fading channel with partial-band interference has been derived and the error rate has been evaluated to show in figures as a function of signal to noise ratio, signal to interference ratio, fading figure, repeated number, partial-band interference fraction and power correlation coefficient between signal and interference. In this paper, we assumed that repeated diversity technique is used in transmitter against fading occurred in mobile radio channel. By comparing the error rate performance in diversity against fading and the obtainable degree of improvement of error performance with diversity technique has been found out. From the result, it is known that error rate performance deteriorates more as $\rho$ becomes small i.e., the partial-band interference gives more effect on error performance than full-band interference. Also when the values of $E_b/N_1$ and $\rho$ are small. as depth of fading diversity technique.

The importance of input wariables of real-time accident consequence assessment model has been analyzed. Partial correlation coefficients of input variables related to the plume and the ingestion exposure have been estimated using latino hypercube sampling technique. It is known that wind speed and growth dilution rate are the most important variable in plume and ingestion exposure, respectively.

The determination of total paraffin, naphthene, and aromatic (PNA) contents in naphtha samples, which were directly obtained from actual refining process, has been studied using near-infrared (NIR) spectroscopy. Each of the total PNA concentrations in naphtha has been successfully analyzed using NIR spectroscopy. Partial least squares (PLS) regression method has been utilized to quantify the total PNA contents in naphtha from the NIR spectral bands. The NIR calibration results showed an excellent correlation with those of conventional gas chromatography (GC). Due to its rapidity and accuracy, NIR spectroscopy is appeared as a new analytical technique which can be substituted for the conventional GC method for the quantitative analysis of petrochemical products including naphtha.

Three different chemical compositions of total paraffin, total naphthene, total aromatic content in naphtha have been successfully analyzed using FT-Raman spectroscopy. Partial least squares (PLS) regression has been utilized to develop calibration models for each composition from Raman spectral bands. The PLS calibration results showed Blood correlation with those of gas chromatography (GC). Using PLS regression, the spectral information related to each composition has been successfully extracted from highly overlapped Raman spectra of naphtha.

Tests of intrinsic-extrinsic motivation, self-efficacy, and creativity were administered to 75 college students. Results were analyzed by Pearson's correlation, partial correlation and Barron and Kenny's(1986) model. The main results were that (1) creativity was positively correlated with intrinsic motivation and negatively correlated with extrinsic motivation. (2) Self-efficacy played an important mediating role in the relationship between extrinsic motivation and creativity, but not in the relationship between intrinsic motivation and creativity, suggesting that extrinsic motivation negatively affects creativity because it lowers self-efficacy, which is intimately related with creativity. (3) The negative effect of extrinsic motivation on creativity was explained by such sub-factors of self-efficacy as self-confidence and preference for difficult tasks, but not by self-regulatory efficacy.
