  • This study aims to analyze the level of members' awareness of records management in the Republic of Korea Army within the institutional context extensively. Accordingly, in-depth interviews were conducted after comparing and analyzing the institutional systems that restricted the members' record management activities. As a result, it was identified that the members were confused by the inconsistency among the systems that defined the work procedures, and that the value of responsibility and efficiency in the records management system does not match the organization's goals. Therefore, the legal justification of the system should be improved in harmony with the responsibilities and efficiency and to match them with the organization's objectives. Moreover, the improved system should be internalized by the members through instructions that are relevant to the content of the system. This study intends to increase awareness in the records management system and improve the system as well.

  • This paper introduces Youngju Ryu's Writers of the Winter Republic: Literature and Resistance in Park Chung Hee's Korea, and examines its significance and limitations. The book examines the relationship between literature and politics during the Park Chung-hee Yushin era, focusing on Yang Sŏng-u, Kim Chi-ha, Yi Mun-gu, Cho Se-hŭi, and Hwang Sok-yong. The books starts by describing the relationship between the U.S. hegemony and the Park Chung-hee regime during the Cold War. The book shows how poets like Yang and Kim fought against the Park Chung-hee regime based on poems, trial records and memoirs, while it describes novelists such as Yi's resistance by how novels envisioned a community against the Park administration based on the keyword "neighborhood." This is significant in that it describes how literature from the Park Chung-hee era was able to stand on the front lines against the regime. However, it is regrettable that because the book adopts a heroic tale to describe their lives and literature, these are illuminated in a somewhat flat way. Also it is noteworthy that the lives and works of novelists after the 2000s were illuminated, but Yang and Kim's life and literature were not described. Furthermore, it is regrettable that women writers were not mentioned and its concept of "politics" is rather shallow. Overall, this book is very significant in that it introduces the relationship between Korean literature and politics in the Korea of the 1970s with rich data and a beautiful style, as well as allowing Korean studies researchers to reflect on the future of Korean studies.

  • We conducted five times surveys, in June, September and October in 2012; June and September 2013, to catalog the mushroom flora in Ulleung-gun, Republic of Korea. More than 400 specimens were collected, and 317 of the specimens were successfully sequenced using the ribosomal DNA internal transcribed spacer barcode marker. We also surveyed the morphological characteristics of the sequenced specimens. The specimens were classified into 2 phyla, 7 classes, 21 orders, 59 families, 122 genera, and 221 species, and were deposited in the herbarium of Korea National Arboretum. Among the collected species, 72% were saprophytic, 25% were symbiotic, and 3% were parasitic. The most common order was Agaricales (189 specimens, 132 species), followed by Polyporales (47 specimens, 27 species), Russulales (31 specimens, 22 species), Boletales (10 specimens, 7 species), and so on. Herein, we also reported the first Bovista species in Korea, which was collected from Dokdo, the far-eastern island of Korea.

  • The technology that recognizes a soldier's motion and movement status has recently attracted large attention as a combination of wearable technology and artificial intelligence, which is expected to upend the paradigm of troop management. The accuracy of state determination should be maintained at a high-end level to make sure of the expected vital functions both in a training situation; an evaluation and solution provision for each individual's motion, and in a combat situation; overall enhancement in managing troops. However, when input data is given as a timer series or sequence, existing feedforward networks would show overt limitations in maximizing classification performance. Since human behavior data (3-axis accelerations and 3-axis angular velocities) handled for military motion recognition requires the process of analyzing its time-dependent characteristics, this study proposes a high-performance data-driven classifier which utilizes the long-short term memory to identify the order dependence of acquired data, learning to classify eight representative military operations (Sitting, Standing, Walking, Running, Ascending, Descending, Low Crawl, and High Crawl). Since the accuracy is highly dependent on a network's learning conditions and variables, manual adjustment may neither be cost-effective nor guarantee optimal results during learning. Therefore, in this study, we optimized hyperparameters using Bayesian optimization for maximized generalization performance. As a result, the final architecture could reduce the error rate by 62.56% compared to the existing network with a similar number of learnable parameters, with the final accuracy of 98.39% for various military operations.

  • The purpose of this study is to review whether the self-esteem of Republic of Korea army officers and noncommissioned officers affect cultural acceptability and at the same time to determine whether these relationships are mediated by adjustment to military life and job satisfaction. For this purpose, we conducted a survey by random sampling of 580 officers and noncommissioned officers serving in the army units located in Gyeonggi Province and Gangwon Province. The collected data was analyzed by a structural equation model, including statistical and correlation analysis. As a result of analysis, self-esteem of the military officers and noncommissioned officers appeared to be mediated only by military life adjustment, or to affect the cultural acceptability mediated by the military life and job satisfaction in turn. Therefore, in order to increase the cultural acceptability of military officers and noncommissioned officers, ROK Army should enhance the self-esteem, job satisfaction and adaptability of them.

  • Among the various fields in the communications, navigation, and surveillance/air traffic management (CNS/ATM) scheme, the surveillance field, which includes an automatic dependent surveillance - broadcast (ADS-B) system and a multilateration (MLAT) system, is implemented using satellite and digital communications technology. These systems provide better performance than radar, but still incur position error. To reduce the error, we propose an efficient information fusion method called the reweighted convex combination method for ADS-B and MLAT systems. The reweighted convex combination method improves aircraft tracking performance compared to the original convex combination method by readjusting the weights given to these systems. In this paper, we prove that the reweighted convex combination method always provides better performance than the original convex combination method. Performance from the fusion of ADS-B and MLAT improves an average of 51.51% when compared to the original data.

  • The objective of this study was to determine the best performing switchgrass (Panicumvirgatum L.) cultivar with three different seeding dates as a bioenergy source in Republic of Korea. Split-plot in time with three replications was performed and three switchgrass cultivars, Carthage (CT), Cave-in-Rock (CIR), and Forestburg (FB) were used in this experiment from 2009 to 2012. Plots were seeded on April 23, May 4, and May 13, 2009 and were harvested once in November each year. No fertilizer was applied to the field for the first year; however, in second and third years (June 2010 and May 2011, respectively), N, $P_2O_5$ and K2O fertilizers were applied in 67,45 and 90 kg $ha^{-1}$, respectively. Soil pH (5.9) and climate condition including temperature ($10.4{\sim}17.5^{\circ}C$) and precipitation (89.4~109.8 mm $month^{-1}$) were suitable for switchgrass cultivation. Total dry matter yields were higher in CT and CIR compared to FB and were 16.9, 15.9, and 4.5 ton $ha^{-1}$, for CT, CIR, and FB, respectively (p<0.0001). The samples were analyzed for dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude fiber (CF), ether extract (EE), and ash. No significant differences in energy content (p = 0.96) and chemical composition among cultivars (p>0.05) were found. Seeding dates did not affect DM yield (ton $ha^{-1}$), chemical composition and energy content significantly (p>0.05). Significant difference was observed for heights among CT, CIR, and FB (177.59, 169.98, and 94.89 cm, respectively, p = 0.0002). In conclusion, based on soil characteristics and climate condition in Korea compared to other countries, switchgrass can be cultivated successfully. Considering dry matter yield and energy content of these three cultivars of switchgrass CT and CIR adapted better to climate in Middle Eastern of Republic of Korea than Forestburg for bioenergy purpose.
