Innovative Human System Interfaces (HSIs) has been a major topic of research of the international Halden Reactor Project (HRP) for many years. Different design concepts have been addressed and prototypes have been implemented and evaluated in the experimental control room facility of HRP. Many of the concepts go far beyond traditional P&ID type displays, and utilize advanced computer graphics and animations. The paper briefly describes some of the concepts, their advantages and disadvantages experienced through evaluations and feedback from users.
The New Right, the Turning Point of 1978, and the Fragility of the American Dream
Alf Tomas TΦnnessen 한국아메리카학회 2015 美國學論集 Vol.47 No.1
The sharp turn to the right in economic policy in recent decades has changed the United States from being a nation of shared prosperity during the Age of Roosevelt (19322-1978) to being a nation of rising inequality and declining social mobility in the Age of Reagan (1978 to the present). The Age of Reagan has seen deregulation of industries, declining power of labor unions, and upward redistribution of wealth. A main reason for this is the rightward tum of the Republican Party since the 1970s. The rise of the New Right in the 1970s helped make the Republican Party more conservative on issues regarding labor and taxes. 1978 was the year of the turning point in policy priorities in Congress, epitomized by the cuts in capital gains taxes. Since the late 1970s tax cuts have mainly benefited the rich, whereas wages for ordinary workers have not kept up with rising living costs. This has made the American Dream fragile for many Americans.

본 사례연구의 사례는 휴대폰의 주된 용도인 커뮤니케이션 기능 외에 체중관리, 식이요법관리를 중심으로 지압, 요가 가이드 등을 묶은 웰빙 기능을 휴대전화에 구현한 과정이다. 휴대전화는 항상 휴대하고 다니는 기기라는 점 때문에 이러한 사용자 개인의 사생활 정보를 관리하기에 적합한 장점을 가지며 특히 개인화 되는 트랜드에 따라 통신 외적인 새로운 기능들이 다양하게 개발되게 되었다. 본 사례연구에서는 실용성 있고 실계 사용자의 생활에 더욱 더 밀접하게 개발하기 위한 방법으로 라이프 스타일을 연구를 통해 20 대 후반의 직장 여성을 페르소나로 설정하여 이에 따라 만들어진 시나리오에 의해 어떠한 기능이 필요할 것인지 결정하고 필요한 콘텐츠를 만들었다. 이러한 사례를 통해 휴대전화가 향후 어떻게 개인화 된 콘텐츠를 계공하고 적절한 사용성을 가진 기능으로 이 콘텐츠를 이용할 수 있는지에 대한 사용자 중심적 디자인의 실제적 사례를 계시하고 향후 보다 개인화 된 기능을 개발 하기 위한 지침으로 계시하고자 한다. This is a case study of a wellbeing feature for mobile phone. Though it is not related communication feature which is major functionality in mobile phone, it becomes a popular feature by users who want to manage private information and life style. To make a feature for practical usage, Personas is used for development and decision, A late 20 years old lady persona is developed to provide context and background information. Based on the persona, usage scenarios and needed contents were designed. From this case study, suggest a design guideline for personalization features in perspective of user experience design.

<P>Supramolecular host–guest systems play an important role for a wide range of applications in chemistry and biology. The prediction of the stability of host–guest complexes represents a great challenge to first-principles calculations due to an interplay of a wide variety of covalent and noncovalent interactions in these systems. In particular, van der Waals (vdW) dispersion interactions frequently play a prominent role in determining the structure, stability, and function of supramolecular systems. On the basis of the widely used benchmark case of the <I>buckyball catcher</I> complex (C<SUB>60</SUB>@C<SUB>60</SUB>H<SUB>28</SUB>), we assess the feasibility of computing the binding energy of supramolecular host–guest complexes from first principles. Large-scale diffusion Monte Carlo (DMC) calculations are carried out to accurately determine the binding energy for the C<SUB>60</SUB>@C<SUB>60</SUB>H<SUB>28</SUB> complex (26 ± 2 kcal/mol). On the basis of the DMC reference, we assess the accuracy of widely used and efficient density-functional theory (DFT) methods with dispersion interactions. The inclusion of vdW dispersion interactions in DFT leads to a large stabilization of the C<SUB>60</SUB>@C<SUB>60</SUB>H<SUB>28</SUB> complex. However, DFT methods including pairwise vdW interactions overestimate the stability of this complex by 9–17 kcal/mol compared to the DMC reference and the extrapolated experimental data. A significant part of this overestimation (9 kcal/mol) stems from the lack of dynamical dielectric screening effects in the description of the molecular polarizability in pairwise dispersion energy approaches. The remaining overstabilization arises from the isotropic treatment of atomic polarizability tensors and the lack of many-body dispersion interactions. A further assessment of a different supramolecular system – glycine anhydride interacting with an amide macrocycle – demonstrates that both the dynamical screening and the many-body dispersion energy are complex contributions that are very sensitive to the underlying molecular geometry and type of bonding. We discuss the required improvements in theoretical methods for achieving “chemical accuracy” in the first-principles modeling of supramolecular systems.</P>
