The purpose of RAM analysis in weapon systems is to reduce life cycle costs, along with improving combat readiness by meeting RAM target value. We analyzed the sensitivity of the RAM analysis parameters to the use of the operating system by using the Markov Process based model (MPS, Markov Process Simulation) developed for RAM analysis. A Markov process-based RAM analysis model was developed to analyze the sensitivity of parameters (MTBF, MTTR and ALDT) to the utility of the 81mm mortar. The time required for the application to reach the steady state is about 15,000H, which is about 2 years, and the sensitivity of the parameter is highest for ALDT. In order to improve combat readiness, there is a need for continuous improvement in ALDT.

This paper deals with the feasibility analysis and alternatives for infrared detector development. The purpose of this paper analyze development requirement and feasibility study in both technology and cost. We get raw input data for system engineering process from development and technical expert, and then analyze cost and technology for development feasibility, and alternative study. Infrared Detector is core component of Thermal Imaging System and developed by ADD from 2006 to 2008 year. Technical level is analyzed by TRL(Technical Readiness Level) and AOA(Analysis of Alternative) is done by development and production cost estimate. We use SEER-H tool for cost estimate, that is parametric cost estimate tool based on Knowledge Base. Also this paper presents risk analysis for project management because it is necessary to risk driver management during the infrared detector development. The result of IR Detector feasibility and alternative study will be used in technical and cost analysis. This study can help those who are related to the cost analysis and development feasibility of other weapons

Mission effectiveness may be defined as a probability that a system can successfully meet an intended mission demand within a given time when operated under specified conditions. This study deals with the Mission effectiveness of a replenishment ships that is performing several types of missions. The essential attributes and their related factors affecting the replenishment missions are established, and then, a mathematical mission effectiveness model is constructed with a replenishment mission characteristics for a basis. Mission effectiveness for a mission is determined by finding the joint probability measure of the following three attributes : operational readiness of the replenishment ships at the start of a mission ; mission reliability of the replenishment ships ; capability of successfully accomplishing intended objectives given an environmental condition. The model is solved analytically. Operational readiness of the replenishment ships in found by the assumed data. Mission reliability and capability are calculated based on the assumed probability distributions. The model would be a useful tool to evaluate mission effectiveness as it is very a replenishment ships.

This descriptive study was conducted to examine the factors affecting core competency, learner motivation, and learner satisfaction of nursing students and to develop effective teaching methods. The subjects of this study were 134 nursing students. The core competencies of nursing students were higher in 3rd grade than in 2nd grade, and the core competency, motivation, and learner satisfaction of the nursing students were higher than those of below average students. The explanatory power of a core competency model constructed using the self-directed learning readiness, teacher-student interaction, and academic achievement was 45.1%. Additionally, the explanatory power of a learner motivation model based on self-directed learning readiness, teacher-student interaction, academic achievement, and learner motivation was 47.5%, while that of a learner satisfaction model constructed using the teacher-student interaction and learner motivation was 43.4%. In conclusion, it is necessary to improve teacher-student interaction and self-directed learning readiness to increase core competency and learner motivation. To increase learner satisfaction, it is necessary to intervene to encourage learner motivation and to make the teaching-student interaction efficient.

The purpose of this study is to examine the mediating effect of interest in the elderly job project and resilience in the relationship between social support and retirement readiness of the MZ·X generation. This survey conducted reliability and frequency analysis, t/f-verification, descriptive statistical analysis, and analysis of reliability and frequency using SPSS 27.0 and AMOS 27.0 programs on the collected data of 359 MZ and X generations of G, Y, and A cities in D and G provinces. Analysis was performed using correlation analysis and structural relationship statistics. As a result of the study, first, it was found that there was a significant correlation between the level of interest in the employment project for the elderly, social support, resilience and readiness for old age. Second, in the relationship between social support and retirement readiness, the degree of interest and resilience of the elderly job project were partially mediated. Therefore, in order to increase the MZ and X generations' interest in and resilience in the job projects for the elderly, the provision of emotional, evaluative, informational, and material support systems as a social support system and the elderly in government agencies such as the Ministry of Health and Welfare, the Ministry of Employment and Labor, and the Ministry of Gender Equality and Family A realistic policy of job business policy is needed.

Awe is recognized as an emotion linked to enhancing openness to new experiences and broadening one's cognitive perspective through the acquisition of new knowledge. This research aimed to investigate awe's impact on consumer behavior in advertising, using a 2 (emotion: awe/control) × 2 (product type: innovative/non-innovative) experimental design with 118 undergraduate students in Seoul, Korea. Findings revealed that awe-inducing advertising significantly increases product preference and positive technology readiness, particularly for innovative products compared to non-innovative ones or when awe is not elicited. The analysis of moderated mediation showed that positive technology readiness plays a mediating role in the relationship between awe induction and product preference. Notably, in the case of innovative products, awe-inducing advertising heightens positive technology readiness, subsequently increasing consumer preference for these products. These results reinforce existing literature on awe's positive effects, demonstrating its role in augmenting consumers' favorable attitudes toward innovative products. The study offers valuable insights for marketing strategies of companies promoting innovative products or services, highlighting the effectiveness of awe-inducing emotional appeals in shaping consumer attitudes towards innovation.

The usage level of SMEs' win-win payment system is still lower than originally expected. In order to find the answer, we studied SMEs' usage performance of win-win payment system and analyzed the influencing factors of SMEs' usage level of win-win payment system. This study found that the more SMEs utilize win-win payment system, the higher they achieve the desired performance in finance, customer, process, learning and growth perspective. And this study found that usage level of win-win payment system is high in order of large corporations' pressure, government policy, and SMEs' readiness. This study is expected to improve win-win growth by increasing usage level of win-win payment system between large corporations and SMEs, while establishing desirable ecosystems.

The interest in on-line services has increased during the last couple of years and there are now several models developed to better understand how customers evaluate e-service quality. In this empirical study we combine the use of the theories of attractive quality and technology readiness so as to explain customer experiences of e-services. A survey was conducted with 188 students at three universities in Sweden, asking how they assess an e-service that enables one to reserve and buy cinema tickets on-line. The main contribution of the study is its provision of evidence on how to interpret and improve customer satisfaction when designing e-services. Our belief is that an organization can gain a clearer grasp of how customer satisfaction is created with an e-service by taking into account customers' experiences with new technology.
