Perkembangan Iptek Dalam Pengelolaan Lingkungan; Strategi Dalam Rangka Transfer Teknologi Lingkungan

Eko-teknologi merupakan strategi baru yang inovatif dalam menunjangpembangunan yang berkelanjutan. Hal ini merupakan prespektif pendekatan yang menjelaskan interdependensi sistem teknologi pengelolaan lingkungan dengan sistem biogeofisik. Pendekatan ini difokuskan pada peran teknologi lingkungan dalam meminimisasikan limbah dan memaksimalkan daur ulang bahan dan enerji. Sejauh mungkin sistem produksi mendekati sistem pencegahan kehilangan bahan yang bermanfaat maupun energi. Bersifat sistemaik, berorientasi ke masa depan, serta efisiensi sik1us melalui pemanfaatan sumber daya alam, energi dan limbahyang dibuang menjadi basis model pengintegrasian sistem biogeofisik kedalam sistem eko-teknologi atau sebaliknya Tuntutan akan kepedulian kerjasama warga masyarakat dan pengambil keputusan menegaskan bahwa eko- eknologi bukan sekedar suatu pendekatannn berpikir atau suatu alat analisis, namun harus ditumbuhkan sebagai etika bagi masyarakat industri, masyarakat luas dan pelaku dalam pengambilan keputusan untuk kelangsungan kehidupan masa depan. Perubahan pradigma dimana lingkungan alam sebagai penyedia sumber bahanbaku serta tempat pembuangan yang tidak terbatas menjadi keterpaduan antara sistem teknologi dan sistem ekologi dalam keberlajutan masa depan

Intoxication with Ornithogalum arabicum is a potential cause of visual impairment and irreversible blindness in dogs

We describe two dogs with persistent visual impairment after initially mild intoxication signs following ingestion of Ornithogalum arabicum plant material. Additionally, a 12-year analysis of the Dutch Poisons Information Centre database additionally reveals that ingestion of Ornithogalum plant material can be potentially life-threatening to companion animals. Further studies are necessary to confirm the involvement of cardiac glycoside-like toxins present in Ornithogalum arabicum and the toxicity of these substances to the retina

Affordances, constraints and information flows as ‘leverage points’ in design for sustainable behaviour

Copyright @ 2012 Social Science Electronic PublishingTwo of Donella Meadows' 'leverage points' for intervening in systems (1999) seem particularly pertinent to design for sustainable behaviour, in the sense that designers may have the scope to implement them in (re-)designing everyday products and services. The 'rules of the system' -- interpreted here to refer to affordances and constraints -- and the structure of information flows both offer a range of opportunities for design interventions to in fluence behaviour change, and in this paper, some of the implications and possibilities are discussed with reference to parallel concepts from within design, HCI and relevant areas of psychology

Clinicopathologic predictors of finding additional inguinal lymph node metastases in penile cancer patients following positive dynamic sentinel node biopsy:a European multicentre evaluation

OBJECTIVES: Following tumour positive sentinel lymph node biopsy (+DSNB), completion inguinal lymph node dissection (ILND) is negative in 84-89% of basins. Thus, ILND after +DSNB may be considered overtreatment resulting in substantial morbidity. This study aimed to develop a predictive model for additional inguinal lymph node metastases (LNM) at ILND following +DSNB using DSNB characteristics to identify a patient group in which ILND might be omitted. PATIENTS AND METHODS: A retrospective study of 407 inguinal basins with a +DSNB of penile cancer patients who underwent subsequent ILND from seven European centres. From the histopathology reports, the number of positive and negative lymph nodes, extranodal extension and size of the metastasis were recorded. Using bootstrapped logistic regression, variables were selected for the clinical prediction model based on the optimisation of Akaike's information criterion. The area under the curve (AUC) of the receiver operating characteristic (ROC) curve was calculated for the resulting model. Decision curve analysis (DCA) was used to evaluate the clinical utility of the model. RESULTS: 64 (16%) of +DSNB harboured additional LNM at ILND. The number of positive nodes at +DSNB (odds ratio (OR) 2.19; 95% confidence interval (CI) 1.17-4.00; p=0.01) and the largest metastasis size in mm (OR 1.06; 95%CI 1.03-1.10; p=0.001) were selected for the clinical prediction model. The AUC was 0.67 (95%CI 0.60-0.74). The DCA showed no clinical benefit of using the clinical prediction model. CONCLUSION: A small but clinically important group of basins harbour additional LNM at completion ILND following +DSNB. While DSNB characteristics were associated with additional LNM, they did not improve the selection of basins in which ILND could be omitted. Thus, completion ILND remains necessary in all basins with a +DSNB

Exploring expression of form, action and interaction

The central theme in Ambient Intelligence is that powerful computation, communication and storage facilities are available, but are invisible. We believe that objects will play an important role as mediators. In order to make models of mediation and to study the mediation of behaviour, traditional modelling techniques, such as foam models, rendering etc. fall short. Although it is easy to make two-dimensional models of screens and front-panels and connect actions to the corresponding buttons, this approach is inadequate for new types of interfaces and behaviours which are not screen-based. Therefore we have experimented with an approach which we call 4D Sketching. The term 4D refers to the fact that it includes sketching in 3D space with the active behaviour adding a fourth, temporal dimension. We use foam, cardboard, a glue-gun, and other easy-to-use materials for the spatial sketching. We use a microprocessor, servo-motors and sensors to sketch active behaviour. The article describes the underlying philosophy, the technical aspects and a number of experiences gathered so-far, including student work from a project called Semotion
