In this paper, we measured the propagation path loss by a ground to air flight communication test at UHF band and analyzed the results. The ground receiving terminal was located at 1,100m above sea level in Cheju Island and the airborne transmit terminal flew at an altitude of 3.5km from 150 to 220km from the ground terminal. In this case, the ground terminal and the airborne terminal are on the Line of Sight. Therefore loss in this communications environment can be predicted based on Free Space Loss. However, in this test, the sea level exists between two terminals, and due to the very small angle of incidence on the reflecting surface due to the long-range communication environment, it is not possible to accurately predict the loss of free space only. Therefore, considering that there are no surrounding obstacles and that a line of sight is secured between the end of two terminals, we applied a plane earth reflection model and a spherical earth reflection model to estimate the propagation path loss and compared with the actual test results. As a result of the comparison, the predicted propagation path loss by a spherical earth reflection model were quite similar to the actual test values.

Purpose: This study was performed to explore factors that influence attitudes toward terminal care in nursing students. Methods: Data were collected using a self-reported questionnaire filled by 175 nursing students at a university in a metropolitan city B. Data were analyzed using descriptive analysis, t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression with the SPSS/WIN 22.0 program. Results: Attitudes toward terminal care in nursing students was significantly correlated with communication competence (r=0.438, P<0.001), spirituality (r=0.374, P<0.001), and gratitude (r=0.318, P<0.001). Communication competence explained 18.7% of the variance in attitudes toward terminal care. Conclusion: The study shows communication competence is an important factor for attitudes toward terminal care in nursing students. Therefore, it is necessary to develop a communication competence enhancement program to foster nursing students with appropriate attitudes toward terminal care.

Purpose: This study was performed to determine the effects of foot reflexology on pain and quality of sleep in patients with terminal cancer. Method: Quai-experimental research design was used. The subjects of this study were consisted of 19 for experimental group and 18 for control group. Visualue Scale(VAS) was used as the measurement tool of pain in this study, Verra & Snyder-Halpern Sleep Scale(VSH) and Visual Analogue Scale(VAS) were used as the measurement tool of perceived quality of sleep. Data were analyzed using statistical methods such as frequency, percent, $x^2$-test, t-test using SPSS WIN 12.0 program. Results: The hypothesis 1 that the experimental group with reflexology has less degree of pain than the control group without reflexology was supported (t=5.41, p<.001). The hypothesis 2 that the experimental group with reflexology has higher degree of VSH Scale than the control group without reflexology was supported(t=2.37, p=.02). The hypothesis 3 that the experimental group with reflexology has the difference among the mean of sleep VAS Scale during the 12 measurement periods was not supported(F=1.63, p=.08), and no significant interactions between group and time. Conclusion: It is considered that reflexology is effective for reducing cancer pain and improving quality of sleep in patients with terminal cancer.

Modern military operations rely heavily on broadband communication and data transmission. Recently, the rising use of intelligent unmanned technology necessitates more frequencies. Free-space optical(FSO) communication can offer high-data-rate communications with high security and no need for licensing. Therefore, the FSO communication holds significant interest and potential in the defense industry. In this paper, we present design of a FSO communication terminal taking Korean domestic weather conditions into account. The domestic atmospheric attenuation is analyzed using several models and two-year meteorological information for a city in Korea, and this analysis is utilized to design the FSO communication terminal. The design results were verified using an FSO communication test bed, and we achieved an Ethernet bandwidth of approximately 1.86 Gbps at a distance of 1.3 km with the optical amplifier output power of the test bed set to about 20 dBm.

There are claims that ESE(Early streamer emission) Air terminals offer a vastly increased zone of protection over that of traditional lightning rods by causing the emission of an upward streamer/leader that will propagate towards the tip of downward leader at an early stage in the attachment process than would occur for a simple rod in the same geometrical configurations. This paper shows the results of comparing test a particular type of ESE air terminals with a simple rod conducted in the KEH HV laboratory, which are lightning impulse voltage test, flashover direction test and corona emission current measurement. The results from this test show a completely random scattering of flashovers to the conventional and ESE air terminals under identical electrics] and geometrical conditions, and thus shows no advantage of one terminal over the other.

Purpose: We conducted a descriptive correlational study to determine a relationship between nurses' awareness of good death and attitudes toward terminal care, which in turn could be used as basic data for improvement of the quality of terminal care at geriatric hospitals. Methods: From April 3, 2013 through April 22, 2013, data were collected from 230 nurses working at geriatric hospitals. Results: Nurses' attitudes toward terminal care showed no significant correlation with awareness of good death, but it was positively correlated with a sense of closeness, a subfactor of awareness of good death. There was negative correlation between emotions regarding a deathbed, a subfactor of attitudes of nurses in charge of terminal patients, and awareness of good death. We found positive correlation between terminal care performance and awareness of good death. Conclusion: This study warrants the need for nursing education catered to characteristics of geriatric hospitals and development of diverse intervention strategies to help them to attain a positive attitude toward death by familiarizing themselves with the concept of good death and enhancing job satisfaction.

Purpose: To develop end-of-life care training programs for nurses who provide in a tertiary hospital, we examined the mediating effects of empathy and resilience on the relationship between their stress and job performance. Methods: This study was conducted with 218 participants at a hospital in B city in South Korea from August 15 through August 30, 2017. Data collected from the participants were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple regression using the IBM SPSS/WIN 21.0 software. Results: Terminal care stress was found to be negatively correlated with empathy competence (r=-0.345, P<0.001), resilience (r=-0.223, P=0.001) and terminal care performance (r=-0.260, P<0.001), whereas empathy (r=0.467, P<0.001) and resilience (r=0.358, P<0.001) were positively correlated with terminal care performance. Empathy had a complete mediating effect (${\beta}=0.409$, P<0.001) on the relationship between terminal care stress and performance, and resilience a partial mediating effect (${\beta}=0.294$, P<0.001). Conclusion: Based on the findings of this study, development of training programs with a focus on empathy and resilience are highly recommended to improve job performance of nurses who provide terminal care in a tertiary hospital.
