Purpose: This study was done to identify the cultural capacity of college nursing students and the relationship of intercultural communication. Methods: The participants were 200 students in colleges of nursing from 6 universities in C city, who understood the purpose of the study and agreed to participate. Collected data were analyzed with t-test, ANOVA, correlation analysis, and stepwise regression analysis using SPSS/WIN 22.0. Results: Cultural sensitivities in this study (r=.372, p<.001), cultural knowledge (r=.399, p=.001), cultural awareness (r=.547, p<.001), and cultural technology (r=.550, p<.001) each showed a statistically significant correlation with intercultural communication skills. Conclusion: The results of this study show that reinforcement of the cultural and intercultural communication ability of college nursing students, in-depth exploration of the cultural area and religious inspection, cultural and professional backgrounds, assessment and consideration of cultural characteristics, nursing diagnosis, and health appropriate to the cultural background. It is suggested that education such as service provision should be conducted systematically.

In this study, We investigated the effects of substrate temperature on the electrical and optical properties of Ga-, B-codoped ZnO(GZOB) thin films. GZOB thin films were deposited on glass substrate with various substrate temperature in the range from R.T. to $500\;^{\circ}C$ by DC magnetron sputtering. In the reslt, GZOB films at $400\;^{\circ}C$ exhibited a low resistivity value of $8.67\;{\times}\;10^{-4}\;{\Omega}-cm$, and a visible transmission of 80% with a thickness of 300 nm. This result indicated that the addition of Ga and B in ZnO films leads to the improvement of conductivity and transparent. From the result, we can confirm the possibility of the application as transparent conductive electrodes.

The primary goal of any communication spacecraft is to provide communication in variety of frequency bands based on mission requirements within the Indian mainland. Some of the spacecrafts operating in S-band utilizes a 6m or larger aperture Unfurlable Antenna (UFA for S-band links and provides coverage through five or more S-band spot beams over Indian mainland area. The Unfurlable antenna is larger than the satellite and so the antenna is stowed during launch. Upon reaching the orbit, the antenna is deployed using motors. The deployment status of any deployment mechanism will be monitored and verified by the telemetered values of micro-switch position before the start of deployment, during the deployment and after the completion of the total mechanism. In addition to these micro switches, a camera onboard will be used for capturing still images during primary and secondary deployments of UFA. The proposed checkout system is realized for validating the performance of the onboard camera as part of Integrated Spacecraft Testing (IST) conducted during payload checkout operations. It is designed for acquiring the payload data of onboard camera in real-time, followed by archiving, processing and generation of images in near real-time. This paper presents the architecture, design and implementation features of the acquisition, processing and Image generation system for Camera onboard spacecraft. Subsequently this system can be deployed in missions wherever similar requirement is envisaged.

The elliptic curve crypto-algorithm is widely used in authentication for IoT environment, since it has small key size and low communication overhead compare to the RSA public key algorithm. If the scalar multiplication, a core operation of the elliptic curve crypto-algorithm, is not implemented securely, attackers can find the secret key to use simple power analysis or differential power analysis. In this paper, an elliptic curve scalar multiplication algorithm using a randomized scalar and an elliptic curve point blinding is suggested. It is resistant to power analysis but does not significantly reduce efficiency. Given a random r and an elliptic curve random point R, the elliptic scalar multiplication kP = u(P+R)-vR is calculated by using the regular variant Shamir's double ladder algorithm, where l+20-bit u≡rn+k(modn) and v≡rn-k(modn) using 2^lP=∓cP for the case of the order n=2^l±c.

This study evaluated the improvement of autistic symptoms during the 4-7 year follow-up in autistic children. Fifty subjects(44 males and 6 females whose age ranged between one to 13 years) diagnosed with DSM-III-R autistic disorder were included in this study. Their autistic symptoms were assessed with DSM-III-R diagnostic criteria of autistic disorder(grouped as A, B and C which include 5, 6 and 5 items respectively). The mean of follow-up duration was 6.4${\pm}$1.1 years. Symptoms between baseline and follow-up were examined according to treatment types, age, sex, IQ and physical problems of them were identified. There were statistically significant decreases of symptom items at follow-up as a whole and A, B and C, respectively. The most symptom decrease occurred in communication and followed social interaction, and activities and interests at follow-up assessment. Symptom items that decreased more than 50% at follow-up evaluation include A1, A2, A3 and B1, B2, B3, B4, B5, and C1, C3. Groups with special education only and combined treatment of special education and seizure pharmacotherapy showed better improvement of symptoms than the group with psychiatric pharmacotherapy with special education. Age was a significant factors in the improvement of symptoms. The author concluded that some autistic children improved with aging, therefore they should be treated actively with special education, pharmacothrapy and other scientific methods.

To reduce the cost of solar electricity, the crystalline-silicon (c-Si) photovoltaic industry is moving toward the use of thinner wafers (100 μm to 200 μm) to achieve a high efficiency. In this field, it is imperative to achieve an effective passivation method to reduce the electronic losses at the c-Si interface. In this article, we review the most promising surface passivation schemes that are available for high-efficiency solar cells.

In this paper, we implemened the simplified Chua's circuit which is replace L to C by real hardware implementation. Because L element has a difficult problem to make a real hardware, L has a saturation characteristic and we also compare with previous Chua's circuit as the result of chaostic attractors creation.

Wide area augmentation system is a system that generates and transmits correction and Integrity information for use in wide area. Typical system is SBAS. In the United States, it operates under the name WAAS, EGNOS in Europe, MSAS in Japan, SDCM in Russia, GAGAN in India. it is developing Korean SBAS which named KASS by 2022 in Korea. SBAS is a standard System that is operated as civil aviation service base and set as international standards by ICAO. So the correction data can only is used for civil SPS receiver. In this paper, we discuss C1P1 DCB estimation which need to use SPS correction service for PPS receiver. Then we analyze C1P1 DCB correction effect under standalone Satellite Navigation and method to use PPS receiver under SPS DGPS. Finally we organize wide area augmentation system for PPS receiver and analysis performance.

We discuss the design and fabrication of CCD or C-MOS imaging lenses with hybrid diffractive / refractive optics. The hybrid lenses are made of optical grade plastic materials. We have been able to significantly reduce the number of elements while maintaining very high optical quality. This paper describes the conception, design, fabrication and evaluation of hybrid lenses in comparison with conventional refractive lenses. The new lens has excellent optical quality, very light weight, compact size and low manufacturing cost.
