There were a lot of attempts in the army to use various domestic thematic maps, but attribute data types of military topographic analysis maps use the FACC of DIGEST, so there is a limit in employing domestic thematic maps with different types of attribute codes. Therefore, this study analyzed the FACC as a data attribute based on the MIL-PRF-89040 of the US Army. Then, VITD was created by changing the attribute codes of domestic thematic maps produced in Korea to fit the FACC. Lastly, it was applied to the analysis of cross-country movement for maneuver defined in FM 5-33 in order to verify if it is applicable in practice. As a result, it was found that the suggested method was helpful in securing the cross-country movement for maneuver. This means that this method can be used not only in producing military topographic analysis maps using domestic thematic maps but in constructing emergency transport routes roads to transport by-products of forest in future.

Method for regulating voltage using a generator voltage regulating device (AVR) is divided in an existing analog system and a digital replacement. Typically, to adjust the voltage by using a brushless excitation system of the type to be reduced for a voltage change under all. The control method of the AVR as a PID (proportional-integral-differential) control method is widely used. However, the control scheme is to reduce the transient response of the control parameters of the controller to the control object. Therefore, if the control target should change, there is a problem, reset the parameters of the controller again. In this study, without having to reset the parameters of the controller for the parameter variations to be controlled iPID (intelligent PID) using a controller designed to obtain a generator AVR system voltage variation is small in response to full load is applied to and through simulations and experiments improved transient response.

In the field of clinical medicine and research, the analysis of such as protein and DNA at the molecular level and even at the cell level are necessary for disease diagnosis and treatment. In many cases, a real time image of samples is needed for the accurate analysis and manipulation of samples since experimental samples are degenerated with time. In this research, a three-dimensional fluorescence microscope device was developed for taking images of protein and DNA inside a single cell and the server-client based image analysis system was made for an integrated management of the real-time images taken from the microscope device. The system consists of a fluorescent measurement device, the associated software and a client program on smartphone. The developed system allows doctors or experimental managers to receive and look at the real-time experimental images taken from the samples of patients anywhere in the emergency, to analyze results and to instantly diagnose the disease and to transfer the results to the patients. As a result, the system is able to be utilized in the implementation of ubiquitous health as well.

The automation system uses PLC to monitor the manufacturing process status of the production product and processes the sensor information transmitted from the sensor. In this paper, we propose a remote surveillance system to monitor the status of control relay used in automation system. The proposed system consists of a control relay module, a one-chip processor module, a computer monitoring system, and a database system that inputs and manages the details of the control relay. The computer monitoring system is configured to monitor the operating condition and life time of the control relay. The database is configured so that the input date of the control relay can be input and corrected, and the operating state information of the control relay can be automatically printed. In the remote monitoring system, the failure status of the control relay is recognized in real time, and the time required for normal operation can be minimized by quickly replacing faulty parts.

Objectives : This study aimed to compare the characteristics of suicide attempts among Korean patients with mixed and non-mixed depression. Methods : Patients who visited the emergency room due to a suicide attempt and participated in the Korean Cohort for the Model Predicting a Suicide and Suicide-related Behavior study were included. Using the Montgomery-Asberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS), 111 patients were classified into the mixed depression (n=46) and non-mixed depression groups (n=65). The Koukopoulos Mixed Depression Rating Scale (KMDRS) score was calculated using the MADRS and YMRS scores. Suicide attempt characteristics were evaluated using the Columbia Suicidal Severity Rating Scale (C-SSRS) and Suicide Intent Scale (SIS). Results : In the mixed depression group, the reason item among the ideation intensity score of the C-SSRS was higher, and the deterrent item score was lower. Scores on the timing and suicide note items of the SIS were higher, and scores for overt communication items were lower in the mixed depression group. The KMDRS score was positively correlated with the C-SSRS ideation intensity and total SIS score. After adjusting for additional variables, the KMDRS scores had a significant effect on the C-SSRS ideation intensity and total SIS scores. Conclusions : The mixed depression group showed a difference in the intensity of suicidal ideation and suicidal intention compared to those in the non-mixed depression group. The overall suicidal ideation intensity and suicidal intention increased according to the degree of mixed depression.
