Experts are concerned about the lack of troops and security vacuum due to the low birth rate in the Republic of Korea. They consider policies to expand the proportion and role of female soldiers to address these issues. In this regard, We would like to introduce the successful use of female personnel in the Ukrainian military and draw implications for the Korean military. This will provide a clue to offset the shortage of troops in the Republic of Korea.

A multi-channel access problem based on hypergraph model in ultra-dense small cell networks is studied in this paper. Due to the hyper-dense deployment of samll cells and the low-powered equipment, cumulative interference becomes an important problem besides the direct interference. The traditional binary interference model cannot capture the complicated interference relationship. In order to overcome this shortcoming, we use the hypergraph model to describe the cumulative interference relation among small cells. We formulate the multi-channel access problem based on hypergraph as two local altruistic games. The first game aims at minimizing the protocol MAC layer interference, which requires less information exchange and can converge faster. The second game aims at minimizing the physical layer interference. It needs more information interaction and converges slower, obtaining better performance. The two modeled games are both proved to be exact potential games, which admit at least one pure Nash Equilibrium (NE). To provide information exchange and reduce convergecne time, a cloud-based centralized-distributed algorithm is designed. Simulation results show that the proposed hypergraph models are both superior to the existing binary models and show the pros and cons of the two methods in different aspects.

The aim of this article was to showcase the endodontic management of a maxillary first molar with an unusual crown and root anatomy. Clinical diagnosis of the roots and root canal configuration was confirmed by a cone-beam computed tomography (CBCT) and the detection of the canals was made using a dental operating microscope. CBCT images revealed the presence of 5 roots with Vertucci type I canal configuration in all, except, in the middle root which had 2 canals with type IV configuration. The 6 canal orifices were clinically visualized under the dental operating microscope. Clinicians should familiarize themselves with the latest technologies to get additional information in endodontic practice in order to enhance the outcomes of endodontic therapy.

International conditions surrounding the Korean Peninsula have been recently undergoing a sudden change. The South-North relations have been defined by severe tensions for many years; however, since the PyeongChang Winter Olympics, relations between the two nations began to thaw, and expectations of unification have been rising. Nevertheless, some still warn that the Democratic People's Republic of Korea is utilizing a "carrot and stick" tactic. With this, recent research revealed that there is a low sense of national security among college students and teenagers in Korea, which magnified the importance of establishing a strong sense of national security and having a national viewpoint. A way to achieve this is for the army, a core institution of national security, to release army records as online contents. This paper takes an in-depth look into the US Army's online contents service, a leading national records management system, and seeks to provide development plans for the Republic of Korea Army's online contents service.

An example of functional army's training wear was developed with careful considerations given to the actual user. Three steps of a functional clothing design process were followed in the design procedure. First, information on the adequacy of the current army's training wear was collected by interviews with 192 persons. Second, the current design and construction of the training wear was altered to meet the user's need from the result of the interview. Third, the performance of the newly designed army's training wear was evaluated for their effectiveness in several aspects such as conditions of the microclimate within clothing, metabolic rate, garment pressure during arm movements and appearance during body motions.

Non-commissioned officers reach 80% of the 6,500 recruitment target, and 88% of the workforce is operated, about 9,500 less than the quota. To solve this problem, RNTC was tested and operated for about four years since 2015. And it was run directly by the Army in 2020. However, the Army has not solved the problem of RNTCs in college. While maintaining RNTC in universities, measures were needed to cope with the decrease in school-age populations, but the army did not address them. The universities tried to achieve two goals: securing students and increasing employment rates, which failed to meet the expectation. This was mainly because students only from particular departments were selected. And this was not what the army aimed to achieve through RNTC. After analyzing the cause of this phenomenon. the problem turned out to be the erroneous perception of RNTC to the general public. In order to eradicate this problem, there needs to be more effective promotion by the Army, and some improvements are also needed in terms of RNTC's selection process. In this paper, we find and describe the problems of the system itself. If this problem is solved, we will be able to not only satisfy the needs of both the Army and the universities, but also produce good non-commissioned officers through the RNTC system.

Visual place recognition (VPR) is a fundamental yet challenging task of mobile robot navigation and localization. The existing VPR methods are usually based on some pairwise similarity of image descriptors, so they are sensitive to visual appearance change and also computationally expensive. This paper proposes a simple yet effective four-step method that achieves adaptive convolutional neural network (CNN) landmark matching for VPR. First, based on the features extracted from existing CNN models, the regions with higher significance scores are selected as landmarks. Then, according to the coordinate positions of potential landmarks, landmark matching is improved by removing mismatched landmark pairs. Finally, considering the significance scores obtained in the first step, robust image retrieval is performed based on adaptive landmark matching, and it gives more weight to the landmark matching pairs with higher significance scores. To verify the efficiency and robustness of the proposed method, evaluations are conducted on standard benchmark datasets. The experimental results indicate that the proposed method reduces the feature representation space of place images by more than 75% with negligible loss in recognition precision. Also, it achieves a fast matching speed in similarity calculation, satisfying the real-time requirement.

A follow-up stool examination was done to know the status of intestinal parasitic infections in Army soldiers who were stationing in Whachon-gun, Kangwon-do, Korea in 1993. Of 233 examined soldiers, Infections with Clonorchis sinensis (0.4%), Metagonimus spp. (0.9%), Echinostomc honene (0.4%), Neoniplostomum seodenis (0.4) and Ginrdin lomblic (3/233) were found. S. honene and N. seouLensis infections were each 75th, and 27th cases in Korea. Regular control program of intestinal parasitic Infections might be able to contribute to diminish the prevalence rate in young Army soldiers in Korea.

The South Korean military has undergone four changes in operating methods since its inception with 31 nursing officers in August 1948. While it initially began as a special unit for nursing and other specialized services, it later expanded to include various fields including technology, administration, and special forces. However, analysis shows that there have been few significant changes in how it operates and remains largely centered around technology, administration, and special forces. With the development of advanced science and technology and a decrease in military resources, there is a need for the South Korean military to proactively expand its use of female personnel, as has been done by the US military, Canadian military, Israeli military with female conscription, and Norwegian military. In order to achieve this, there needs to be a cultural shift towards co-ed military units, improvements in facilities and equipment, adequate pay and benefits, and resolution of childcare issues through institutional reforms.
