This study was a non-equivalence-based Quasi experimental study comparing the difference in communication ability, emotional intelligence (EQ), self-esteem, and interpersonal abilities between an experimental group with communication training and a non-control group. The subjects of the study were nurses working for D university hospital located in C city and comprised an experimental group of 21 people and a control group of 21 people. From April to May 2017, the experimental group took communication training programs, which were designed to improve communication capacity, emotional intelligence, self-esteem, and interpersonal ability for a total of four sessions (for 2 hours a week), and pre-post examination was conducted for the validity of the study. For data analysis, the SPSS for Windows 23 was used for the mean and standard deviation of pre-post tests, and U-test of the independent sample Mann-Whitney and the Wilcoxon code order test of the corresponding sample were carried out. The study results indicate that, compared with the control group, the experimental group showed communication capacity (Z=-3.361, p<.05), emotional intelligence (Z=-2.209, p<.05), self-esteem (Z=-1.633, p<.05), and interpersonal relationship (Z=-2.577, p<.05). After the communication training program, scores of communication capacity, emotional intelligence (EQ), self-esteem, and interpersonal competence of the experimental group increased significantly, and all hypotheses were supported. These results suggest that nurses' use of communication training experience in performing nursing work in a clinical setting would improve communication skills, emotional intelligence (EQ), self-esteem, and interpersonal skills and provide therapeutic communication and effective nursing, thereby enhancing patients' satisfaction and contributing to the improvement of nursing quality.

HVAC transmission lines must be designed to satisfy environmental regulations. Therefore it is necessary to pre-evaluate environmental problems for transmission line designer using prediction program. In this study, environmental design software, TLCALC(Transmission Line CALCulation) for transmission lines was developed as a comprehensive window program. It has 6 modules that are audible noise, radio noise, television noise, magnetic field, electric field and conductor surface gradient. TLCALC solved a few problems in use of the existing foreign tools and took several advantages as follows; (1) It is a common tool that solves calculating limitations of foreign formulas, (2) It has wide application ranges and enhances accuracy of prediction. (3) It can be applied to almost transmission line configurations in Korea. (4) Experienced designers can get the results of calculation within about 15 minutes. Because the use of TLCALC is easy and practical, this program will be usefully applied to the environmental friendly design and construction of transmission lines. In the future, it is expected that public complaints and social environmental cost will be reduced by the use of TLCALC.

Many research demonstrations and commercial applications have been tried to develop face detection and recognition systems. Human face detection plays an important role in applications such as access control and video surveillance, human computer interface, identity authentication, etc. There are some special problems such as a face connected with background, faces connected via the skin color, and a face divided into several small parts after skin region segmentation in generally. It can be allowed many face detection techniques to solve the first and second problems. However, it is not easy to detect a face divided into several parts of regions for reason of different illumination conditions in the third problem. Therefore, we propose an efficient modified skin segmentation algorithm to solve this problem because the typical region segmentation algorithm can not be used to. Our algorithm detects skin regions over the entire image, and then generates face candidate regions using our skin segmentation algorithm For each face candidate, we implement the procedure of region merging for divided regions in order to make a region using adjacency between homogeneous regions. We utilize various different searching window sizes to detect different size faces and a face detection classifier based on a back-propagation algorithm in order to verify whether the searching window contains a face or not.

This study was conducted for the evaluation of the effect of Dementia prevention nursing program on Urinary 17-KS, 17-OHCS, and Blood Na, Cl, K, Ca, P, cholesterol. The sample for the present study was composed of 16 demented elderly in D care center for the elderly in K city. The Dementia prevention nursing program consisted of concept memory training, music therapy, and art therapy. The program was performed twice a week and about ninety minutes was consumed for one session. The program had been administered for 8 weeks. We checked Urinary 17-KS, 17-OHCS, and Blood Na, Cl, K, Ca, P, cholesterol before and after the program. Statistical analysis was performed by using descriptive statistics and Wlicoxon signed rank test of SAS system for window 6.12. The result were follows : 1. Urinary 17-KS 17-KS score increased significantly after intervention(p=0.005). 2. Urinary 17-OHCS 17-OHCS score increased significantly after intervention(p=0.001). 3. Blood Na, Cl, K, Ca, P, cholesterol Na(p=0.0002), Cl(p=0.0001), K(p=0.0001), Ca(p=0.0028), decreased significantly after intervention. The results show that Dementia prevention nursing program increases Urinary 17-KS, 17-OHCS, and decreases Blood Na, Cl, K, Ca, P, cholesterol. In conclusion, the Dementia prevention nursing program can be used for the effective measure to decrease stress of the Demented elderly.

Novel charge trap type memory devices with reoxidized oxynitride gate dielectrics made by NO annealing and reoxidation process of initial oxide on substrate have been fabricated using 0.35 $\mu \textrm{m}$ retrograde twin well CMOS process. The feasibility for application as NVSM memory device and characteristics of traps have been investigated. For the fabrication of gate dielectric, initial oxide layer was grown by wet oxidation at $800^{\circ}C$ and it was reoxidized by wet oxidation at $800^{\circ}C$ after NO annealing to form the nitride layer for charge trap region for 30 minutes at $850^{\circ}C$. The programming conditions are possible in 11 V, 500 $\mu \textrm{s}$ for program and -13 V, 1ms for erase operation. The maximum memory window is 2.28 V. The retention is over 20 years in program state and about 28 hours in erase state, and the endurance is over $3 \times 10^3$P/E cycles. The lateral distributions of interface trap density and memory trap density have been determined by the single junction charge pumping technique. The maximum interface trap density and memory trap density are $4.5 \times 10^{10} \textrm{cm}^2$ and $3.7\times 10^{18}/\textrm{cm}^3$ respectively. After $10^3$ P/E cycles, interlace trap density increases to $2.3\times 10^{12} \textrm{cm}^2$ but memory charges decreases.

The measurement-based verification for intensity modulated radiation therapy (IMRT) is a time-and labor-consuming procedure. Instead, this study aims to develop a MU fluence reconstruction method for IMRT QA. Total actual fluences from treatment planning system (TPS, Eclipse 8.6, Varian) were selected as a reference. Delivered leaf positions according to MU were extracted by the dynalog file generated after IMRT delivery. An in-house software was develop to reconstruct MU fluence from the acquired delivered leaf position data using MATLAB. We investigated five patient's plans delivered by both step-and-shoot IMRT and sliding window technologies. The total actual fluence was compared with the MU fluence reconstructed by using commercial software (Verisoft 3.1, PTW) and gamma analysis method (criteria: 3%/3 mm and 2%/1 mm). Gamma pass rates were $97.8{\pm}1.33$% and the reconstructed fluence was shown good agreement with RTP-based actual fluence. The fluence from step and shoot IMRT was shown slightly higher agreement with the actual fluence than that from sliding window IMRT. If moving from IMRT QA measurements toward independent computer calculations, the developed method can be used for IMRT QA. A point dose calculation method from reconstructed fluences is under development for the routine IMRT QA purpose.
