This study is intended to look into the effects of small business startup environments on failure burden and startup failure. To achieve this, a survey was carried out to 300 small business CEOs in Seoul. The results were as follows. First, the effect of startup environments on failure burden showed that management environment, business environment, internal organizational environment and external organizational environment had a negative effect on failure burden. Second, the effect of startup environments on financial and non-financial losses showed that startup management environment, startup business environment and internal organizational environment had a negative effect on financial and non-financial losses. Third, the effect of failure burden on startup failure showed that failure burden had a positive effect on financial and non-financial losses. Consequently, this study indicates that internal organizational commitment and communication are important attributes affecting failure burden, financial and non-financial losses, compared with management quality, entrepreneurship and business environment.

The purpose of this study is, first, to empirically verify the relationship between the influences of the start-up performance and the inherent fear factor of failure on the start-up performance through the preparation of the start-up. Second, this study aims to prove the influence of the moderating effect of social support on the relationship between start-up preparation and the burden of start-up failure. The research subjects were sampled and analyzed by 298 start-ups who are currently starting their own businesses. This study founds that preparation of start-up items, which is a subordinate theory of start-up preparation, had a significant effect on start-up performance, and that anxiety about failure had a significant effect on start-up performance. Using the SPSS statistical program, the hierarchical regression analysis proved the moderating effect of social support in the relationship between star-tup preparation, start-up failure burden and startup performance. Furthermore, the moderating effect of social support among start-up preparation, start-up failure burden and start-up achievement was analyzed, but no significant results were found for start-up failure burden. Besides, the effect of the opposite concept of independent variables on the dependent variables at the same time is to be analysed.

Frailty is highly prevalent among patients with heart failure (HF) and independently predicts adverse outcomes. However, optimal frailty definitions, assessments, and management in HF remain unclear. Frailty is common in HF, affecting up to 80% of patients depending on population characteristics. Even pre-frailty doubles mortality risk versus robust patients. Frailty worsens HF prognosis through systemic inflammation, neurohormonal changes, sarcopenia, and micronutrient deficiency. Simple screening tools like gait speed and grip strength predict outcomes but lack HF-specificity. Comprehensive geriatric assessment is ideal but not always feasible. Exercise, nutrition, poly-pharmacy management, and multidisciplinary care models can help stablize frailty components and improve patient-centred outcomes. Frailty frequently coexists with and exacerbates HF. Routine frailty screening should guide supportive interventions to optimize physical, cognitive, and psychosocial health. Further research on HF-specific frailty assessment tools and interventions is warranted to reduce this dual burden.

A probabilistic based systems approach is addressed in this study for the reliability prediction of solid rocket motors (SRM). To achieve this goal, quantitative Failure Modes, Effects and Criticality Analysis (FMECA) approach is employed to determine the reliability of components, which are integrated into the Fault Tree Analysis (FTA) to obtain the system reliability. The quantitative FMECA is implemented by burden and capability approach when they are available. Otherwise, the semi-quantitative FMECA is taken using the failure rate handbook. Among the many failure modes in the SRM, four most important problems are chosen to illustrate the burden and capability approach, which are the rupture, fracture of the case, and leak due to the jointed bolt and O-ring seal failure. Four algorithms are employed to determine the failure probability of these problems, and compared with those by the Monte Carlo Simulation as well as the commercial code NESSUS for verification. Overall, the study offers a comprehensive treatment of the reliability practice for the SRM development, and may be useful across the wide range of propulsion systems in the aerospace community.

With the development of RAIM techniques for single failure, there has been increasing interest in the multiple failure problem. There have been many approaches to tackle the problem from various points of view. This paper approaches to two failure problem with total least squares (TLS) technique, which has rarely been addressed because TLS requires a great number of computations. In this paper, the special form of the observation matrix H, that is, one column is exactly known, is exploited so as to develop an algorithm in a sequential form, which reduces computational burden. The algorithm makes us enjoy the advantages of TLS without much computational burden. The proposed algorithm is verified through a numerical simulation.

In wavelength-division-multiplexing(WDM) networks a link failure may cause the failure of several high-bit-rate optical channels, thereby leading to large data loss. Recently, various protection and restoration mechanisms have been proposed to efficiently deal with this problem in mesh networks. Among them, dedicated path protection(DPP) is a promising candidate because of its ultra-fast restoration time and robustness. In this work we investigate the issue of planning and optimization of WDM networks with DPP. Integer linear programming(ILP), in particular, is one of the most common exact method to solve the design optimization problem for protected WDM networks. Traditional ILP formalizations to solve this problem rely on the classical flow or route formulation approaches, but both these approaches suffer from a excessively high computational burden. In this paper, we present a variable-aggregation method that has the ability of significantly reducing the complexity of the traditional flow formulation. We compare also the computational burden of flow formulation with variable aggregation both with the classical flow and route formulations. The comparison is carried out by applying the three alternative methods to the optimization of two case-study networks.

The purpose of study was to examine the entrepreneurial supporting policy and the entrepreneurship which can affect the entrepreneurial intention, and to prove the moderating effect of the business failure burden and the self-efficacy on the relationship of the entrepreneurial supporting policy, entrepreneurship and the entrepreneurial intention through the empirical study in the fusion of industries. We used data from 321 survey participants by using structured questionnaires, excluding dishonest respondents, and statistical analysis was conducted using SPSS 18.0 statistic package. We used hierarchical regression technique to prove our hypothesis. The results showed that education and marketing support which are part of the entrepreneurial supporting policy in the fusion of industries will have positive influence on innovativeness, pro-activeness and risk acceptability which are part of entrepreneurship. It has been reported that only funding support has positive influence on entrepreneurship pro-activeness. The results also indicated that the entrepreneurial supporting policy will have positive influence on the entrepreneurial intention, but business failure burden and self-efficacy will have no moderating effect in the relation between the entrepreneurial supporting policy and the entrepreneurship. The theoretical and practical implications of the findings were discussed and the directions for future research were presented.

Heart failure (HF) is a significant global health concern, particularly in Asia, where over half of the world's population resides. Despite advances in treatment, the burden of HF is expected to rise in the region due to the aging population and an increase in non-communicable diseases associated with HF risk. This narrative review examines the current state of HF in Asia, highlighting differences in treatment utilization, underrepresentation of Asian individuals in clinical trials, emerging therapies, and implementation strategies, including the potential use of polypills and the need for expanded HF training opportunities for healthcare providers.

While the large-scale retirement of the second baby boomers is predicted, new beginnings such as re-employment and start-up of prospective retirees who attempt to switch careers before and after retirement based on the skills and expertise accumulated in the industrial field are very important in terms of society. Therefore, this study established a research model based on Shapero's start-up event model, a representative theory explaining start-up intention and behavior. In the direct variable affecting the start-up motivation of prospective retirees, factors affecting positive (+) and negative (-) factors In order to comprehensively grasp it, family support and the burden of failure were set as parameters to verify the effect of these factors on the intention to start a business. As a result, a positive (+) influence relationship was found on the effect of the retiree's start-up motivation on the burden of failure, the start-up motivation on the family support, the start-up motivation on the start-up intention, and the family support on the start-up intention. It was found that the start-up motivation had a positive (+) effect on the start-up intention through family support. In other words, for prospective retirees, who are mainly middle-aged, the threshold for start-up has been very low due to technological advances, but nevertheless, family support was found to be a very important factor in the conditions of investing retirement funds and capital, which are important in family relationships. However, it was confirmed that the burden of failure had a negative (-) effect on the start-up intention, and the loss of investment and fear of repayment of the loan appeared as a large burden. Accordingly, it is proposed that prospective retirees who are considering starting a business be able to thoroughly prepare for a start-up through the support of their families, and to operate a specialized outplacement start-up education program that can learn about raising funds and efficient management of funds. It is expected to systematically support retirees' preparation for start-ups, reduce the burden of failure, and ultimately increase the likelihood of a successful start-up.

Heart failure (HF) stands as a prevalent chronic ailment, imposing a substantial burden on global healthcare systems due to recurrent hospitalizations, intricate management, persistent symptoms, and polypharmacy challenges. The augmentation of patient safety and treatment efficacy across various care stages, facilitated by a multidisciplinary HF team inclusive of a clinical pharmacist, emerges as paramount. Evidence underscores that the collaborative engagement of a physician and a clinical pharmacist engenders proficient and secure management, forestalling avoidable adversities stemming from drug reactions and prescription inaccuracies. This synergistic approach tailors treatments optimally to individual patients. Post-discharge, the vulnerability of HF patients to re-hospitalization looms large, historically holding sway as the foremost cause of 30-day readmissions. Diverse strategies have been instituted to fortify patient well-being, leading to the formulation of specialized transitional care programs that shepherd patients effectively from hospital to outpatient settings. These initiatives have demonstrably curtailed readmission rates. This review outlines a spectrum of roles assumed by clinical pharmacists within the healthcare cohort, spanning inpatient care, transitional phases, and outpatient services. Moreover, it traverses a compendium of studies spotlighting the affirmative impact instigated by integrating clinical pharmacists into these fields.
