Das System der Umweltprüfungen in Deutschland
Reinhard Hendler 경희대학교 법학연구소 2009 경희법학 Vol.44 No.3
Neben der Umweltverträglichkeitsprüfung bestehen vier weitere Prüfungen, die zumindest auch den Umweltschutz betreffen. Jede dieser Prüfungen weist eine besondere Funktion und damit eine sachliche Existenzberechtigung auf. Doch hat das umfangreiche Prüfungswesen zur Folge, dass bei der Verwirklichung großer Infrastrukturprojekte (Flughäfen, Autobahnen, Kraftwerke etc.) beachtliche zusätzliche Kosten und Zeiterfordernisse entstehen. Für die Zukunft kommt es darauf an, noch mehr als bisher alle Möglichkeiten auszuschöpfen, die verschiedenen Verfahren zu koordinieren oder gar zu verbinden und Doppelarbeit zu vermeiden. Unabhängig hiervon mag auch die Frage gestellt werden, ob zwischen Aufwand und Ertrag des ausgedehnten ökologischen Prüfungswesens noch eine angemessene Relation besteht. Eine breite kritische Diskussion hierüber wird allerdings in Deutschland zurzeit nicht geführt.

We have been exploring routes and systems alternative to the oxocuprates and the oxomanganates and searched for super-conductivity and large magnetoresistance in rare earth compounds, particularly, in the family of layered metallic rare earth halidesand rare earth carbides. Here we review the superconducting properties of YC2,La2C3, and RE2C2X2 (RE¼ Y, La; X¼ Cl, Br, I) aswell as some recent results of the large magnetoresistance eect in the ferromagnet GdI2.
A SECURITY ARCHITECTURE FOR THE INTERNET OF THINGS
( Reinhard Behrens ),( Ali Ahmed ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.12
This paper demonstrates a case for an end-to-end pure Application Security Layer for reliable and confidential communications within an Internet of Things (IoT) constrained environment. To provide a secure key exchange and to setup a secure data connection, Transport Layer Security (TLS) is used, which provides native protection against replay attacks. TLS along with digital signature can be used to achieve non-repudiation within app-to-app communications. This paper studies the use of TLS over the JavaScript Object Notation (JSON) via a The Constrained Application Protocol (CoAP) RESTful service to verify the hypothesis that in this way one can provide end-to-end communication flexibility and potentially retain identity information for repudiation. As a proof of concept, a prototype has been developed to simulate an IoT software client with the capability of hosting a CoAP RESTful service. The prototype studies data requests via a network client establishing a TLS over JSON session using a hosted CoAP RESTful service. To prove reputability and integrity of TLS JSON messages, JSON messages was intercepted and verified against simulated MITM attacks. The experimental results confirm that TLS over JSON works as hypothesised.
THE NAVIER-STOKES EQUATIONS WITH INITIAL VALUES IN BESOV SPACES OF TYPE B-1q,∞+3/q
Reinhard Farwig,Yoshikazu Giga,Pen-Yuan Hsu 대한수학회 2017 대한수학회지 Vol.54 No.5
We consider weak solutions of the instationary Navier-Stokes system in a smooth bounded domain $\Om \subset {\mathbb R}^3$ with initial value $u_0\in L^{2}_{\sigma}(\Om)$. It is known that a weak solution is a local strong solution in the sense of Serrin if $u_0$ satisfies the optimal initial value condition $u_0\in B^{-1+3/q}_{q,s_q}$ with Serrin exponents $s_q>2, q>3$ such that $\frac2{s_q} + \frac3q =1$. This result has recently been generalized by the authors to weighted Serrin conditions such that $u$ is contained in the weighted Serrin class $\int_0^T (\tau^\alpha \|u(\tau)\|_q)^s\dd\tau<\infty$ with $\frac{2}{s} + \frac{3}{q} =1-2\alpha$, $0<\alpha<\frac12$. This regularity is guaranteed if and only if $u_0$ is contained in the Besov space $B^{-1+3/q}_{q,s}$. In this article we consider the limit case of initial values in the Besov space $B^{-1+3/q}_{q,\infty}$ and in its subspace ${\stackrel{\circ}{B}}{}^{-1+3/q}_{q,\infty}$ based on the continuous interpolation functor. Special emphasis is put on questions of uniqueness within the class of weak solutions.
