Effective interventions to reduce work-related exposures are available for many types of work-related diseases or injuries. However, knowledge of the impact of these interventions on injury or disease outcomes is scarce due to practical and methodological reasons. Study designs are considered for the evaluation of occupational health interventions on occupational disease or injury. Latency and frequency of occurrence of the health outcomes are two important features when designing an evaluation study with occupational disease or occupational injury as an outcome measure. Controlled evaluation studies—giving strong indications for an intervention effect—seem more suitable for more frequently occurring injuries or diseases. Uncontrolled evaluation time or case series studies are an option for evaluating less frequently occurring injuries or diseases. Interrupted time series offer alternatives to experimental randomized controlled trials to give an insight into the effectiveness of preventive actions in the work setting to decision and policy makers.
Standardization A Multisciplinary Field of Research
Henk J,de Vries 표준인증안전학회 2012 표준인증안전학회지 Vol.2 No.2
This paper shows which disciplines can contribute tostandardization research by confronting a characterization of standardization with a systematic listing of sciences. The paper argues that standardization typically requires a multidisciplinary approach in which business research might provide the interconnection between the contributions from many other disciplines.

This study contributes to our understanding of competitive dynamics in international sports by investigating national participation in athletics. Recent scholarship has suggested that national elite sport policies follow strategic rationales when dedicating scarce resources to participation in international sport. Therefore, the study builds on the structure-conduct-performance paradigm of industrial organization and assumes that countries’ participation in international sport responds to competitive opportunities. Contrary to our expectations, countries seem to be attracted to highly concentrated and densely populated disciplines in which success prospects might be rather low. Thus, participation in international sport does not follow strategic considerations about competitive opportunities as suggested by the structure-conduct-performance-paradigm. Rather, national elite sport policies seem to resemble to some extent imitative behavior. Thus, the findings indicate the need to complement the ‘outside-in’ perspective of the structure-conduct-performance paradigm of industrial organization with an ‘inside-out’ perspective in the tradition of the resource based view. What we need is a more thorough investigation of how national elite sport systems and their distinctive capabilities evolve.
Series Solution of High Order Abel, Bernoulli, Chini and Riccati Equations
Henk, Koppelaar,Peyman, Nasehpour Department of Mathematics 2022 Kyungpook mathematical journal Vol.62 No.4
To help solving intractable nonlinear evolution equations (NLEEs) of waves in the field of fluid dynamics we develop an algorithm to find new high order solutions of the class of Abel, Bernoulli, Chini and Riccati equations of the form y' = ay<sup>n</sup> + by + c, n > 1, with constant coefficients a, b, c. The role of this class of equations in NLEEs is explained in the introduction below. The basic algorithm to compute the coefficients of the power series solutions of the class, emerged long ago and is further developed in this paper. Practical application for hitherto unknown solutions is exemplified.
Understanding Urban Growth : a Conceptual Model
Jianquan Cheng, Henk Ottens, Ian Masser, Jan Turkstra 서울시립대학교 도시과학연구원 2003 International journal of urban sciences (IJUS) Vol. No.
Understanding the urban growth system is a prerequisite for modelling and forecasting future trends of urban land use/cover change and its ecological impacts. As urban growth involves various actors with different patterns of behaviour, we argue that scientific understanding must be based on elaborated complexity theory and a multidisciplinary framework. The theoretical analysis can provide a guideline for selecting modelling methods currently available in complexity modelling and in remote sensing and GIS environments. This paper first proposes a conceptual model for defining urban growth and its complexity, in which spatial, temporal and decision-making complexity are distinguished as separate domains. Second, this paper links the conceptual model with the major current methods of modern urban modelling, such as cellular automata, fractals, neural networks, multi-agent, spatial statistics etc. This confrontation enables the possibilities of various modelling methods to understand urban growth complexity to be indicated. Third, this paper evaluates the operational implementation of representative methods based on criteria such as interpretability, data need and GIS embedded ness. Finally, two case studies are used to test the conceptual model.
The German Reunification: An Analysis a Quarter Century After 1989/90
Klaus-Dietmar Henke 통일연구원 2014 International journal of korean unification studie Vol.23 No.1
The paper analyses the process of the German Unification in 1989/90 against the background of the historical burdens imposed on the so-called “German Question” since the 19th century. It unravels the complex unification process, which had been completed in less than only one year, and delivers a summary of this epochal radical change from the perspective of the year 2014. On the one hand, the analysis shows the political-institutional, economic and social turning points in the now twenty five years lasting alignment of living conditions in East and West Germany. On the other hand, it reveals the psychological-mental distortions the East German population had to bear during the extremely challenging process of unification. The paper always keeps half an eye on the lessons which can be learned from the historic experience of Germany for a possible unification of North and South Korea. In all due precaution, it concludes with a number of recommendations.
