Engineering Metrology for Pedestrian Falls Prevention and Protection
In-Ju Kim
- Springer
- 25 Mars 2022
- 9783030957469
This book explains how to improve the validity, reliability, and repeatability of slip resistance assessments amongst a range of shoes, floors, and environments from an engineering metrology viewpoint-covering theoretical and experimental aspects of slip resistance mechanics and mechanisms.Pedestrian falls resulting from slips or falls are one of the foremost causes of fatal and non-fatal injuries that limit people's functionality. There have been prolonged efforts globally to identify and understand their main causes and reduce their frequency and severity.
This book deals with large volumes of information on tribological characteristics such as friction and wear behaviours of the shoes and floors and their interactive impacts on slip resistance performances. Readers are introduced to theoretical concepts and models and collected evidence on slip resistance properties amongst a range of shoe and floor types and materials under various ambulatory settings. These approaches can be used to develop secure design strategies against fall incidents and provide a great step forward to build safer shoes, floors, and walking/working environments for industries and communities around the world.
The book includes many case studies. -
This book examines pedestrian shoe-floor slip resistance from an engineering standpoint in order to better understand friction and wear behavior. This analysis includes an extensive investigation into the surface properties of shoes and flow, and the measurement of dynamic friction and other mechanical and physical aspects of shoe-floor tribology. Lastly, the book proposes a measurement concept for the identification and classification of operational floor surfaces under a range of different conditions.Novel techniques and methods are proposed that can improve the reliability of slip resistance assessments. The current state of knowledge is critically examined and discussed from a tribological perspective, including aspects like friction, wear, lubrication and the mechanical behavior of shoes, floors and their wider environment. Further, the book reports on extensive experimental investigations into the topographical characteristics of shoe and floor surfaces and how they affect slip resistance. Slips resulting in pedestrian falls are a major cause of injuries and deaths for all age groups. This important book provides essential insights for researchers, practicing engineers and public safety officials wishing to learn about how the risk of pedestrian slips can be assessed and understood.

L'objet ancien ; art et temps contemporain
Kim Ju-Young
- Editions l'harmattan
- 8 Avril 2020

Qu'est-ce qu'un objet ancien de nos jours ? À partir de quelle période peut-on considérer un objet comme objet ancien ? C'est un objet toujours vivant mais qui demande une autre définition que celle d'outil ou d'objet décoratif. L'objet ancien porte l'empreinte de la vie d'un autre temps. Les traces visibles et invisibles sur l'objet ancien témoignent de la présence immortelle de la vie et caractérisent l'objet. Comment reconnaître cette vie et définir l'essence de cet objet qui porte la trace du temps et de la main de l'homme ? Ces questions invitent à rechercher les objets anciens apparus dans les oeuvres d'artistes contemporains en redéfinissant leur forme et leur essence au-delà de leur matérialité. Ainsi compris, l'objet ancien définit une notion de l'art contemporain et n'est plus un simple matériau de l'art.

Representation Theory, Number Theory, and Invariant Theory
Jim Cogdell, Ju-Lee Kim, Chen-Bo Zhu
- Birkhäuser
- 19 Octobre 2017
- 9783319597287
This book contains selected papers based on talks given at the "Representation Theory, Number Theory, and Invariant Theory" conference held at Yale University from June 1 to June 5, 2015. The meeting and this resulting volume are in honor of Professor Roger Howe, on the occasion of his 70th birthday, whose work and insights have been deeply influential in the development of these fields. The speakers who contributed to this work include Roger Howe's doctoral students, Roger Howe himself, and other world renowned mathematicians. Topics covered include automorphic forms, invariant theory, representation theory of reductive groups over local fields, and related subjects.

Reforming State-Owned Enterprises in Asia
Naoyuki Yoshino, Farhad Taghizadeh-Hesary, Chul Ju Kim, Kunmin Kim
- Springer
- 23 Février 2021
- 9789811585746
This book analyzes state-owned enterprises (SOEs), which are still significant players in many Asian economies. They provide essential public services, build and operate key infrastructure, and are often reservoirs of public employment. Their characteristics and inherent competitive advantages as publicly owned enterprises allow them to play these critical roles. Their weaknesses in governance and inefficiencies in incentive structures, however, also often lead to poor performance.
SOEs must be efficient, transparent, and accountable to level the playing field for private companies, secure the growth of a vibrant private sector, and achieve sustained and inclusive economic growth. This book analyzes the reform of SOEs in Asia, the results of which are mixed.
The volume concludes that some key conditions generally need to be met for SOE reforms to be successful: national bureaucracies must have the capacity to implement the reforms, and adverse impacts on international trade and investment must be avoided. -
International Development Cooperation of Japan and South Korea
Huck-Ju Kwon, Tatsufumi Yamagata, Eunju Kim, Hisahiro Kondoh
- Palgrave macmillan
- 1 Janvier 2022
- 9789811646010
This book examines the evolution of foreign aid policy in Japan and South Korea, analyzing policy rationales, institutional developments and policy choices. The book searches for new strategies of international development cooperation in an uncertain world. The book compares two countries' policies in a unique way: pairs of Japanese and Korean scholars examine same policy themes in separate chapters, contrasting differences and similarities. This book will be of great value to scholars of international development cooperation, public policy and East Asian politics.
