Purpose - Consumers have memories of their past time that they have not experienced. So consumers want to experience the past time and get pleasure through historical contents such as movies or dramas. This is because the re-created the past time sets the identity of the consumers who live today, and in the process, it give consumers emotional comfort. Consumers do not remember and sympathize with all of their historical time. In general, consumers remember the time that their communities are proud of. As s result, historical content is seen as a hero, and through that, consumers can check their identity. Also consumers experience positive emotions such as self-esteem, gratitude and pride through identification with heroes. That is, through historical contents, consumers can identify themselves and replace the current negative emotions with positive ones. Therefore, this study presents narrative identity and historical nostalgia that can affect positive evaluation of historical contents and suggest the factors the can induce such effects. This study was conducted to explain what the consumption effect of historical content is from a marketing perspective and what constitutes a component of historical content as a factor driving this effect. Research design, data, and methodology - This study has developed a questionnaire with 8 Hypotheses. The Films ('Masquerade(2012)', 'Roaring Current(2014)', 'Assassination(2015)', 'The Age of Shadow(2016)') and dramas('Six Flying Dragon(2015-2016)', 'Mr. Sunshine(2018-2019)') were used as experimental contents. 268 college students participated in this empirical study, and structural equation model was used to verify hypotheses. Results - Frist, narrative identity affects positive evaluation of historical contents. Nostalgia affect positive evaluation of historical contents. and narrative identity affects positive response of historical nostalgia. Second, character act relevance, circumstance similarity, and character attractiveness have positive influence upon response of narrative identity. Lastly, empathy for story and vividness of representation have also positive influence upon response of historical nostalgia. Conclusion - This study contributes to the theoretical and managemental development of historical contents. This study shows that narrative identity and historical nostalgia are important for success of historical contents. In order for historical content to be successful, it must manage elements of character act relevance, circumstance similarity, and character attractiveness, empathy for story and vividness of representation.

In this study, the stability and economic feasibility of a MSE (Mechanically stability earth) wall with a pre-cast concrete pacing panel was investigated for a standard section of highway. Based on the design criteria, the MSE walls of the panel type were designed considering the load conditions of the highway, such as the dead load of the concrete pavement, traffic load, and impact load of the barrier. The length of the ribbed metal strip was arranged at 0.9H according to the height of the MSE walls. Because the length of the reinforcement was set to 0.9H according to the height of the MSE wall, the external stability governed by the shape of the reinforced soil was not affected by the height increase. The factor of safety (FOS) for the bearing capacity was decreased drastically due to the increase in self-weight according to the height of the MSE wall. As a result of examining the internal stability according to the cohesive gravity method, the FOS of pullout was increased and the FOS of fracture was decreased. As the height of the MSEW wall increases, the horizontal earth pressure acting as an active force and the vertical earth pressure acting as a resistance force are increased together, so that the FOS of the pullout is increased. Because the long-term allowable tensile force of the ribbed metal strip is constant, the FOS of the fracture is decreased by only an increase in the horizontal earth pressure according to the height. The panel type MSE wall was more economical than the block type at all heights. Compared to the concrete retaining wall, it has excellent economic efficiency at a height of 5.0 m or more.

The purpose of this study was to examine the mediating effects of experiential avoidance on the relationships between life stress, depression and smartphone addiction in nursing college students. This study was conducted using a descriptive survey design. Participants were 283 nursing college students attending freshmen and sophomore yearsat one university in Jeollanam-do. Data were collected from September 1 to 15, 2015 using self-report questionnaires. Data were analyzed using descriptive statistics, Pearson's correlation coefficient, hierarchical regression and Sobel test with SPSS 21.0. There were significant positive correlations between life stress, depression, smartphone addiction and experiential avoidance. Experiential avoidance partially mediated the relationship between life stress and depression of nursing students. Additionally, experiential avoidance partially mediated the relationship between their life stress and smartphone addiction. The results show that experiential avoidance plays a key role in psychopathology and grows with depression and smartphone addiction. Based on the present findings, nursing interventions should be developed to decrease experiential avoidance, with additional consideration towards the relationship between life stress and experiential avoidance, in order to prevent depression and smartphone addiction among nursing college students.

Objectives: The aim of this study was to explore whether emergency bell could shorten door to electrocardiograms (ECG) time in chest pain patients presenting to emergency department (ED) by self-transport. Methods: This was a planned 6-month before-and-after interventional study design. We set up the emergency bell in walk-in patients' waiting room. Prior to the change, patients were triaged before an ECG was obtained. In new process, as soon as patient with chest pain push the emergency bell, emergency physicians examined patient and prioritized performing ECG. We analyzed door to electrocardiograms (DTE) times for patients with chest pain and ST segment elevation myocardial infarction (STEMI) patients between two periods. Results: During the enrollment period, a total of 63 patients called emergency bell. The median DTE time was 6 min (interquartile range: 3.0 - 9.0) and 82.5% received an ECG within 10 minutes, and only three patients were STEMI. DTE time in patient with chest pain was not different between two periods (p=0.980). Before intervention period, 15 walk-in patients admitted in ED for STEMI and 53.8% of STEMI patients received an ECG within 10 minutes. After intervention period, total 19 walk-in patients admitted in ED for STEMI. Of these, 89.5% met the time requirement. Conclusion: Because a small portion of patients with chest pain activated the emergency bell, new strategy for promotion of emergency bell must be needed.

The study investigated information about the effects of message framing on colorectal cancer(CRC) screening related health beliefs and compliance with the CRC screening test within the theoretical framework of the prospect theory and the Health belief model (HBM). This study was using a non-randomized controlled quasi-experimental design. One hundred and sixty-four in the industrial workers who were currently nonadherent to guidelines for receiving screening were assigned to one of three experimental conditions: (a) gain-framed message, (b) loss-framed message, and (c) general-framed message. CRC screening-related health beliefs was self-reported after the intervention. And the immunoassay Fecal Occult Blood Test (iFOBT) kit was collected at 1 week. The research finding were analyzed by $x^2$ test and one-way ANOVA using SPSS 21.0. The loss-framed message group had higher perceived susceptibility, severity and benefit than the gain-framed message and general message. The participation rate for the immunoassay Fecal Occult Blood Test(iFOBT) was highest in the loss-framed message group. The loss framed messages more effective to enhance screening behavior. The present results provide a theoretical basis for developing educational guidelines for CRC testing and could be used for performing comprehensive approach by predicting and suggesting the practical effects according to message type in advance.

This paper deals with characteristics analysis of a permanent magnet (PM) linear generator using analytical methods for wave energy harvesting. The wave energy is carried out from the movement of a yo-yo system. A linear generator using permanent magnets to generate a magnetic force itself does not require a separate power supply and has the advantage of simple maintenance. In addition to the use of a rare earth, a permanent magnet having a high-energy density can be miniaturized and lightweight, and can obtain high energy-conversion efficiency. We derived magnetic field solutions produced by the permanent magnet and armature reaction based on 2D polar coordinates and magnetic vector potential. Induced voltage is obtained via arbitrary sinusoidal input. In addition, electrical parameters are obtained, such as back-EMF constant, resistance, and self- and mutual-winding inductances. The space harmonic method used in this paper is confirmed by comparing it with finite element method (FEM) results. These facilitate the characterization of the PM-type linear generator and provide a basis for comparative studies, design optimization, and machine dynamic modeling.

In this paper, the Zynq system-on-chip (SoC) platform is used to design an adaptive noise reduction and edge-detection system using partial reconfiguration. Filters are implemented in a partially reconfigurable (PR) region to provide high computational complexity in real-time, 1080p video processing. In addition, partial reconfiguration enables better utilization of hardware resources in the embedded system from autonomous replacement of filters in the same PR region. The proposed edge-detection system performs adaptive noise reduction if the noise density level in the incoming video sequences exceeds a given threshold value. Results of implementation show that the proposed system improves the accuracy of edge-detection results (14~20 times in Pratt's Figure of Merit) through self-reconfiguration of filter bitstreams triggered by noise density level in the video sequences. In addition, the ZyCAP controller implemented in this paper enables about 2.1 times faster reconfiguration when compared to a PCAP controller.
