이 연구는 케냐 해양대학 항해학과 교과과정의 개발을 위해 다음과 같은 다양한 연구들이 수행되었다. 먼저 2장에서 케냐의 교육 및 환경 여건을 살펴보기 위해 케냐의 전반적인 상황과 JKUAT 및 동 대학 기관공학과의 교과과정을 살펴보았다. 이어 3장에서는 항해학과 교과과정의 표준으로 삼아야 할 IMO STCW 협약 해기교육요건과 IMO 모델 코스를 살펴보았다. 이어 4장에서는 항해학과 교과과정의 개발에 참고하기 위해 모범적인 해기교육을 실시하고 있는 미국의 USMMA와 CMA, 필리핀의 PMMA와 MAAP, 한국의 한국해양대학교, 중국의 대련해사대학교, 그리고 베트남의 VIMARU와 HCMUT의 교과과정을 각각 살펴보았다. 마지막으로 5장에서는 이상의 검토 결과를 토대로 케냐 해양대학의 항해학과 교과과정을 제시하였다.

Poor project performance has been noted as the bane in the construction industry globally. This paper sought to investigate, by way of literature, the performance patterns of construction projects in Kenya since independence (1963-2018). This was informed by reports of undesirable project performance in the industry. This descriptive study used available studies previously done in this subject area. In sum, literature is replete with evidence on a myriad of challenges facing the execution of projects. The study established that generally, the project performance is poor and has assumed a chronic trajectory spanning over five decades. On average, the findings reveal that 35-60% of projects initiated in Kenya face cost overruns while time overrun is most severe with 35-73% projects overrunning their schedule. In addition, the findings problematize the issue of plurality of performance measurement regimes in the construction industry. Here, it was observed that no singular construct exists to objectively measure the various facets that constitute the 'health' of a project. This paper has contributed to the body of knowledge by examining the performance patterns in Kenya for over fifty years while at the same time identifying the bottlenecks inherent in projects execution. Importantly, the conceptual performance efficiency framework derived in the current study presents a paradigm shift in the monitoring and evaluation of projects. To this end, an in-depth analysis is recommended on the interaction of efficiency enablers in the buildup of performance efficiency index (PEI). Similarly, a further inquiry is recommended on the integration and impact of the proposed framework in the management of projects.

In view of the mounting cost of rehabilitating deteriorating infrastructure, further compounded by intensified environmental concerns, it is now obvious that the evolvement and application of advanced composite structural materials to complement conventional construction materials is a necessity for sustainable construction. This study seeks alternative fill materials (polymer-based) to the much-limited cement concrete used in concrete-filled steel tubular structures. Polymers have been successfully used in other industries and are known to be much lighter, possess high tensile strength, durable and resistant to aggressive environments. Findings of this study relating to elasto-plastic characteristics of polymer concrete filled steel composite beams subjected to uniform bending highlight the enormous increase in stiffness, strength and ductility of the composite beams, over the empty steel tube. Moreover, polymer based materials were noted to present a wide array of properties that could be tailored to meet specific design requirements e.g., ductility based design or strength based design. Analytical formulations for design are also considered.
