For the past 70 years, an intense rivalry has persisted on the Korean Peninsula, and North Korea's nuclear and missile threats are becoming increasingly imminent. Facing a shortage of military resources, South Korea has pursued a national defense reform, significantly reducing the number of units and troops while focusing on ground forces. However, North Korea's strategic objective of unifying South Korea through surprise attacks, prompt responses, and combined nuclear and missile assaults remains unchanged. The central issue in this context revolves around determining the appropriate size of the Korean military's standing forces. This study employs the concept of net assessment as a novel method to ascertain the optimal size of the Korean military. Threats, strategic objectives, doctrine, and unit rotations are simultaneously considered from the enemy's perspective. In anticipation of security risks on the Korean Peninsula, an acceptable troop size will be proposed using the net assessment approach to calculate the appropriate standing force size.

In the business market, prices are typically subject to negotiation between exchange partners and buyers’ perceptions of the relationships with suppliers have a central role for supplier success and for establishing profitable prices (Hinterhuber & Liozu, 2015). Suppliers that seek to achieve price levels above the average market prices of offerings need to convince buyers of a favorable price/quality ratio (Töytäri, Rajala, & Alejandro, 2015). To date, however, research on absolute prices paid by buyers to suppliers, relative prices paid as compared to the average price level in a product category, or exchange partners’ perceptions of prices charged in business relationships remains limited. Extant work on buyer-supplier relationships has most commonly focused on costs rather than prices as economic outcomes of interest (e.g., Cannon & Homburg, 2001; Kalwani & Narayandas, 1995). The purpose of this research is to deepen the understanding of buyers’ price assessments in business relationships. Specifically, this research seeks to further illuminate how relationship inputs provided by suppliers influence buyers’ assessments of the price level charged and their satisfaction with the price/quality ratio provided by the suppliers. The relationship inputs examined include buyers’ perceptions of supplier relationship-specific investments, long-term orientation, and relationship planning. In addition, this research considers two relationship parameters, that is, buyers’ commitment to the supplier and dependence from the supplier. Based on a sample of executives of different buyer firms, this research examines net effects and combinatory effects of the relationship factors on buyers’ evaluations of economic outlay. While the study of net effects offers insights into the effects of single antecedents on the outcomes across a sample of cases, the analysis of combinatory effects delineates (configurations of) antecedents sufficient for bringing about the outcomes of interest (e.g., Leischnig, Henneberg, & Thornton, 2016). Knowledge of these effects helps assess what relationship inputs and what combinations thereof may act as potential remedies for buyers’ price-related resentment in business The findings of this research show alternative configurations of relationship inputs and relationship characteristics sufficient for the two outcomes of interest. In addition, this research shows that individual relationship inputs and characteristics can have opposite effects on the outcomes, depending on how they combine with other antecedent conditions. Moreover, the results of this research reveal that specific antecedent factors differ in terms of causal coreness for the two outcomes of interest. In summary, these findings add to the net effect analysis and provide a more detailed and nuanced understanding of how relationship attributes impact buyers’ price assessments in business relationships.

The Optical Wide-field patroL-Network (OWL-Net) is a global optical network for Space Situational Awareness in Korea. The primary operational goal of the OWL-Net is to track Low Earth Orbit (LEO) satellites operated by Korea and to monitor the Geostationary Earth Orbit (GEO) region near the Korean peninsula. To obtain dense measurements on LEO tracking, the chopper system was adopted in the OWL-Net’s back-end system. Dozens of angle-only measurements can be obtained for a single shot with the observation mode for LEO tracking. In previous work, the reduction process of the LEO tracking data was presented, along with the mechanical specification of the back-end system of the OWL-Net. In this research, we describe an integrity assessment method of time-position matching and verification of results from real observations of LEO satellites. The change rate of the angle of each streak in the shot was checked to assess the results of the matching process. The time error due to the chopper rotation motion was corrected after re-matching of time and position. The corrected measurements were compared with the simulated observation data, which were taken from the Consolidated Prediction File from the International Laser Ranging Service. The comparison results are presented in the In-track and Cross-track frame.
