The purpose of this study was (a) to develop carbon nanotube-based shock absorbers for reducing potentially harmful impact forces and excessive foot pronation, and (b) to briefly determine how the effects of carbon nanotube-based shock absorbers on biomechanical variance during drop landing. A university student(age: 24.0 yrs, height: 176.2 cm, weight: 679.5 N) who has no musculoskeletal disorder was recruited as the subject. Hardness, specific gravity, tensile strength, elongation, 100% modulus, tear strength, split tear strength, compression set, resilience, vertical GRF, and loading rate were determined for each material. For each dependent variable, a descriptive statistics was used for different conditions. The property test results showed that tensile strength, tear strength, split tear strength, compression set, and resilience in carbon nanotube-based shock absorbers were greater than general Ethylene Vinyl Acetate(EVA). These indicated that resistance against variable strength in developed carbon nanotube-based shock absorbers were greater than general EVA. In vertical GRF of CNTC was less than those of EVA during drop landing and loading rate of CNTC was greater than EVA. It seems that the use of CNT can be a effective way of reducing and controlling shock from impact.

본 연구는 "한국교육고용패널" 조사를 이용하여 학자금 대출이 대졸자 직업탐색 기간에 미치는 영향에 대해 추정하였다. 특히 학자금 대출이 그 유형에 따라 대출의 보유자에게 상이한 영향을 미칠 가능성을 고려하였다. 추정 결과에 따르면, 첫째, 학자금 보증 대출의 경우 비대출자에 비해 상대적으로 더 긴 직업탐색 기간을 갖는 것으로 나타났으며, 이는 원리금 상환을 고려하여 더 높은 임금을 제안받기 위한 선택일 개연성이 있다고 사료된다. 둘째, 취업 후 상환 학자금 대출의 경우 비대출자에 비해 상대적으로 더 짧은 직업탐색 기간을 소비할 뿐만 아니라 역시 더 낮은 임금을 받는 것으로 나타났다. 이와 같은 사실은 이 대출의 보유자가 취업 시까지 납부할 이자는 유예되지만, 축적되는 이자 부담과 여타 학자금 대출 제도에 비해 상환 계획이 짧다는 점 등에 부담을 느끼는 심리적 부담에 의한 역기능이 발생한다고 해석할 수 있다.

This paper investigates the determinants of students' success in Vietnam through conducting online interviews and surveys with 2,500 Vietnamese students at eight famous universities in Vietnam. By applying both SPSS 22 and STATA software, the study is to evaluate the impact of four driver factors, which affect GPA, language efficacy, and personal achievement. These factors are psychological perspective, home environmental, student demographic, and school environmental. The research results emphasize a positive effect of psychological and home-environmental determinants, but the negative effect of school environmental factors on the students' success. Besides, the relationship between demographics and student success was tested and indicated that male students have a better language learning ability, but a low level of academic achievement than female students. The results also point out the impact of religious affiliation and ethnicity on personal achievement. Non-religious students are better achievers than those having a religion or those in minority ethnicity. Moreover, accumulated schooling years are negatively associated with students' success. The more working experience students accrued, the higher possibility they are successful. Finally, the finding provides an insight into students' success that might be useful to government authorities and other universities in designing policies for enhancing the quality of education.

Purpose: Distributed leadership (DL) is a comprehensive and analytical way to understand how leadership manifests itself among people and in the context of a complex organization. With technological advances and seemingly ever-changing pressures on the environment, it is important for education leaders to represent their practice. This study aims to discuss the significance of DL and its role in education. Research design, data and methodology: The present researcher used Qualitative Content Analysis (QCA) because it is credible, transferable, dependable, and confirmable proving its trustworthiness. To begin with, QCA entails a sufficient representation of the social realities being studied, credibility. Results: The investigation of this study indicates that the documents are in the proper functioning of schools to highlight the potential impact of collaborative practices, many of which require sharing school fees. DL can be meant as "influence relationships," discussions in groups, government, and non-leaders, about how teachers influence each other, and teamwork was easy. Conclusions: This study suggests that management can significantly impact organizational changes in management practices to distribute or skip something planned. DL is not a panacea, plan, or formula. Rather, it is a way to get under the skin of local leadership and restore the potential for change in the organization.

The purpose of this study is to explore the link between job satisfaction and organizational commitment at higher education institutions (HEIs) in emerging countries such as Vietnam and to determine extrinsic work factors that influence job satisfaction. Higher education is critical for socio-economic growth and the overall development of each country. Hence, an understanding of what motivates employees' actions and attitudes should be obtained before determining the extent of employee satisfaction. The conceptual model was developed by incorporating job satisfaction-related variables, their relationships, and the impact of job satisfaction on organizational commitment. An empirical study was conducted on a study sample of public and private universities, with 316 academics and non-academic employees surveyed. The current study employed the partial least squares structural equation modeling to test the proposed hypotheses. The results reveal a positive and significant relationship between job satisfaction and organizational commitment. The findings confirm that extrinsic work factors (job itself, supervision, working conditions, payment, and reward and recognition) have a positive and significant relationship with job satisfaction. Furthermore, the study indicates that employees at HEIs who have a high level of ability utilization and supervisor support are more likely to be satisfied with their jobs.

The extensive use of polymeric matrix composites in the athletic sector may be attributed to its high strength-to-weight ratio, production economy, and a longer lifespan than conventional materials. This study explored the impact of carbon nanotubes on the properties of different composite field sports equipment components. The test specimens were fabricated using the compression molding technique. The insertion of carbon nanotubes increases mechanical properties related to the process parameters to account for an improvement in the stick sections' overall performance. The dynamic response of functionally graded reinforced nanocomposite wire structure is examined in this paper on the bases of high-order hyperbolic beam theory lined to the size-dependent nonclassical nonlocal theory under the external mechanical load due to the physical activities. Finally, the impact of different parameters on the stability of nanocomposite structures is discussed in detail.
