In this study, a method for estimating the amount of urination for men, was suggested and its performance was evaluated. This study is a preliminary one for the development of a health monitoring system that needs un-constraining, non-intrusive and long-term measurements in daily life. To estimate the amount of urination, a wide weighing plate with load cell was built and the difference in a man's weights between before and after urination was measured while he was standing on the plate. The results showed that the amount of urination can be estimated with the measured weight difference under the condition of mild movements. The largest measurement error of the suggested method was 40g, which means that this method can be applied to health monitoring in daily life. It is expected that the results of this study will be the basis for developing practical un-constraining and non-intrusive health monitoring system for daily use at home.

This study examined the effects of scenario-based education for patients with difficulty urination on nelaton knowledge, nelaton confidence, and nelaton catheterization skill ability of nursing college students. The data for this study were collected from May to June 2019, and were conducted for the third grade nursing students located in J city. A non-equivalent control group pretest-posttest design was used in 75 junior nursing college students subjects who were assigned to the experimental group 37 and the control group 38. The collected data was analyzed through the ��2-test, independent t-test and paired-test. There were significant differences in nelaton confidence(t=4.60, p<.001), nelaton catheterization skill ability(t=3.46, p=.001). But scenario-based education was found to be insignificant in the nelaton knowledge of nursing students. Difficulty urination scenario-based education can be used as an effective educational intervention to improve nelaton confidence and nelaton catheterization skill ability. However, in nelaton knowledge, it is necessary to verify the effectiveness of education through additional research.

Current clinical methods for diagnosing urination disorder are invasive, expensive, and very inconvenient to perform continuous monitoring. EIT is a non-invasive technique that injects electrical current through an external electrodes and measures the induced voltage to visualize the internal electrical (impedance) characteristics, which makes it possible to monitor bladder conditions with low cost. The signal characteristics of the measured voltage data changes according to the current pattern injected through the electrode and affects reconstruction performance. In this paper, image reconstruction performance is compared and analyzed according to the injected current patterns to maximize the sensitivity to the variation of bladder size.

The imprecise real-time system provides flexibility in scheduling time-critical tasks. Most scheduling problems of satisfying both 0/1 constraint and timing constraints, while the total error is minimized, are NP-complete when the optional tasks have arbitrary processing times. Liu suggested a reasonable strategy of scheduling tasks with the 0/1 constraint on uniprocessors for minimizing the total error. Song et at suggested a reasonable strategy of scheduling tasks with the 0/1 constraint on multiprocessors for minimizing the total error. But, these algorithms are all off-line algorithms. In the online scheduling, the NORA algorithm can find a schedule with the minimum total error for the imprecise online task system. In NORA algorithm, EDF strategy is adopted in the optional scheduling. On the other hand, for the task system with 0/1 constraint, EDF_Scheduling may not be optimal in the sense that the total error is minimized. Furthermore, when the optional tasks are scheduled in the ascending order of their required processing times, NORA algorithm which EDF strategy is adopted may not produce minimum total error. Therefore, in this paper, an online algorithm is proposed to minimize total error for the imprecise task system with 0/1 constraint. Then, to compare the performance between the proposed algorithm and NORA algorithm, a series of experiments are performed. As a conseqence of the performance comparison between two algorithms, it has been concluded that the proposed algorithm can produce similar total error to NORA algorithm when the optional tasks are scheduled in the random order of their required processing times but, the proposed algorithm can produce less total error than NORA algorithm especially when the optional tasks are scheduled in the ascending order of their required processing times.

Coastal disasters have become one of the most important issues in every coastal country. In Korea, coastal disasters such as storm surge, sea level rise and extreme weather have placed many coastal regions in danger of being exposed or damaged during subsequent storms and gradual shoreline retreat. A storm surge is an onshore gush of water associated with a tow pressure weather system, typically in typhoon season. However, it is very difficult to predict storm surge height and inundation due to the irregularity of the course and intensity of a typhoon. To provide a new scheme of typhoon damage prediction model, the scenario which changes the central pressure, the maximum wind radius, the track and the proceeding speed by corresponding previous typhoon database, was composed. The virtual typhoon scenario database was constructed with individual scenario simulation and evaluation, in which it extracted the result from the scenario database of information of the hereafter typhoon and information due to climate change. This virtual typhoon scenario database will apply damage prediction information about a typhoon. This study performed construction and analysis of the simulation system with the storm surge/coastal inundation model at Masan coastal areas, and applied method for predicting using the scenario of the storm surge.

Purpose: This study was conducted to investigate patients' characteristics and actual conditions of home-based services offered by a free-standing hospice center. Methods: A retrospective review was performed with the medical records of 75 patients who received home-based hospice care from a free-standing hospice center from January 2014 through December 2014. Results: Most patients (54.7%) were enrolled via self-directed referral. The reason for the service termination was death at home 25.3%, admission to a hospice ward 50.7%, hospitalization 22.6% and patients' refusal 2.7%. Seventy three patients had cancer, and two patients had ALS. Among all, 58.7% were in a dying phase, and 34.7% were almost completely bedfast at the time of their enrollment in this study. When they enrolled, the patients' physical symptoms were characterized as pain (89.4%), sleep disturbance (71.2%), urinary difficulties (35.8%) and defecation difficulties (47.8%). Among all, 77.4% terminated the home visit service within one month. The mean frequency of the home visits was 3.25 (${\pm}3.98$), and less than five in 82.7% of patients. The mean frequency of the phone service was 3.40 (${\pm}3.12$). The frequency of doctor's home visits was $1.21{\pm}0.79$ on average, and the figure increased when patients' conditions turned unstable. Conclusion: It is necessary to develop a home-based hospice care model with consideration of patients' characteristics and the actual service conditions delivered by free-standing hospice facilities.
