Cutaneous Rosai-Dorfman disease (RDD) is a rare, benign condition mainly affecting the lymph nodes and sometimes involving the skin. RDD is notorious for its poor response to medication, and surgery is often the preferred treatment option for limited lesions. Herein, we present a case of cutaneous RDD in a 49-year-old woman with multiple facial nodules that showed minimal response to treatment with steroids, isotretinoin, and methotrexate. The diagnosis of cutaneous RDD was confirmed based on histopathological examination. The patient showed minimal response to medication; however, electrosurgery resulted in a relatively good cosmetic response. The present case demonstrates that electrosurgery can be an effective treatment option for cutaneous RDD, especially in case of patients with multiple lesions. The rarity of this disease and the limited reports on its management highlights the need for further research on the efficacy of different surgical modalities for cutaneous RDD.

<P>Three-dimensional (3D) printers have attracted considerable attention from both industry and academia and especially in recent years because of their ability to overcome the limitations of two-dimensional (2D) processes and to enable large-scale facile integration techniques. With 3D printing technologies, complex structures can be created using only a computer-aided design file as a reference; consequently, complex shapes can be manufactured in a single step with little dependence on manufacturer technologies. In this work, we provide a first demonstration of the facile and time-saving 3D printing of two-terminal micro-electromechanical (MEM) switches. Two widely used thermoplastic materials were used to form 3D-printed MEM switches; freely suspended and fixed electrodes were printed from conductive polylactic acid, and a water-soluble sacrificial layer for air-gap formation was printed from poly(vinyl alcohol). Our 3D-printed MEM switches exhibit excellent electromechanical properties, with abrupt switching characteristics and an excellent on/off current ratio value exceeding 10<SUP>6</SUP>. Therefore, we believe that our study makes an innovative contribution with implications for the development of a broader range of 3D printer applications (e.g., the manufacturing of various MEM devices and sensors), and the work highlights a uniquely attractive path toward the realization of 3D-printed electronics.</P> [FIG OMISSION]</BR>

This paper proposes power supply assessment model of renewable energy generators(REG). The REGs have uncertainty of resource supply. Therefore, the REGs have probabilistic power characteristics. The analytical probabilistic power assessment model of the REGS is developed in this paper. This paper is focused on Wind Turbine Generator(WTG) and Solar Cell Generator(SCG). The assessment model based on probabilistic model considering uncertainty of resources(wind speed and solar radiation) is developed. The power is assessed from expected value based the proposed model. The proposed model is applied two simple systems, which have a WTG or a SCG in this paper.
