In this paper, we investigate some conditions which are equivalent to fuzzy $r$-homeomorphisms and give some characterizing theorems for fuzzy $r$-semicontinuous, $r$-semiopen and $r$-semiclosed maps.

An optimal design method to determine the lengths of finger phalanges is proposed especially for anthropomorphic design. The quality of designs are quantified by several measures of global isotropy for design, Also, for an example, optimal design of two fingers is performed and the results are compared with the anatomical data.

Background: Ovarian cancer remains a major worldwide health care issue due to the lack of satisfactory diagnostic methods for early detection of the disease. Prior studies on the role of serum cancer antigen 125 (CA125) and human epididymis protein 4 (HE4) in detecting ovarian cancer presented conflicting results. New tools to improve the accuracy of identifying malignancy are urgently needed. We here aimed to evaluate the diagnostic utility of tissue CA125 and HE4 gene expression in comparison to serum CA125 and HE4 in discriminating benign from malignant pelvic masses. Materials and Methods: One-hundred Egyptian women were enrolled in this study, including 60 epithelial ovarian cancer (EOC) patients and 20 benign ovarian tumor patients, as well as 20 apparently healthy women. Preoperative serum levels of CA125 and HE4 were measured by immunoassays. Tissue expression levels of genes encoding CA125 and HE4 were determined by quantitative real time polymerase chain reaction (qRT-PCR). The diagnostic performance of CA125 and HE4, measured either as mRNA or protein levels, was evaluated by receiver operating characteristic (ROC) curves. Results: The serum CA125+HE4 combination and serum HE4, with area under the curve (AUC) values of 0.935 and 0.932, respectively, performed significantly better than serum CA125 (AUC=0.592; P<0.001). Tissue CA125 and HE4 (AUC=1) performed significantly better than serum CA125 (P<0.001), serum HE4 (P=0.016) and the serum CA125+HE4 combination (P=0.018). Conclusions: Measurement of tissue CA125 and HE4 gene expression not only improves discriminatory performance, but also broadens the range of differential diagnostic possibilities in distinguishing EOC from benign ovarian tumors.

Die Rechtsschutzversicherung ist als eine echte Schadenversicherung eine neue Versicherung, die $Spezialit{\ddot{a}}t$ des versichertes Risikos hat. Das bedeutet, dass der Rechtschutzversicherer nur bestimmte vertraglich vereinbarte Risiken $tr{\ddot{a}}gt$. Diese Risiken sind in den Allgemeinen Bedingungen $f{\ddot{u}}r$ die Rechtsschutzversicheurng (ARB) im Zusammenhang mit Versicherungsvertragsgesetz (VVG) ${\S}$ 125 exact beschrieben. VVG ${\S}$ 125 spricht allegemein von Leistung des Versicherers im vereinbarten versicherten Umfang. Entscheidend ist also die Vereinbarung in den ARB, welche in ${\S}$ 1 die Kostentragung $f{\ddot{u}}r$ den Versicherten als Hauptleistung des Versicherers beschrieben ist. Also in den VVG ${\S}{\S}$ 125 bis 129 gibt es keine Definition ${\ddot{u}}ber$ die Sparte der Rechtsschutzversicherung, jedoch mindestens es $w{\ddot{a}}re$ $m{\ddot{o}}glich$, diese Sparte zu definieren. Um die $k{\ddot{u}}nftige$ Produktentwicklung nicht zu hindern, $enth{\ddot{a}}lt$ die Vorschrift keine gesetzliche Definition der Rechtsschutzversicherung nach Angabe der amtlichen $Begr{\ddot{u}}ndung$. Weil in Korea die Rechtsschutzversicherung relativ neu in Versicherungsmarket ist, sind daher VVG ${\S}{\S}$ 125 ein gutes gesetzgeberisches Vorbild, um pragmatisch und auch dazu rechtswissenschaftlich zu diskutieren und diese fsetzustellen. Im Schritt von Ausdehnungen der juristischen Dienstleistung $w{\ddot{a}}re$ es $n{\ddot{o}}tig$, zu betrachten, wie Leistungsumfang des Versicherers in der Rechtsschutzversicherung erweitert werden kann. And noch dazu ist die Informationspflicht des Versicherers in Hinsicht auf Versicherungsunfall und Leistungsumfang noch weitert zu ${\ddot{u}}berlegen$, weil diese Sparte der Rechtsschutzversicherung noch professioneller als die anderen Versicherungsbereiche ist.

Among 23 cytochrome P450s, CYP125A4 was proposed as a putative monooxygenase based on the high level of amino acid sequence homology (54% identity and 75% similarity) with the well characterized C27-steroid $Mycobacterium$ $tuberculosis$ CYP125A1. Utilizing MTBCYP125A1 as a template, homology modeling of SPCYP125A4 was conducted by Accelrys Discovery Studio 3.1 software. The modeled SPCYP125A4 structure with lowest energy value was subsequently assessed for its stereochemical quality and side-chain environment. The final model was generated by showing its active site through the molecular dynamics. The docking of steroids showed broad specificity of SPCYP125A4 with different orientation of ligand within active site facing the heme. One poses of C27-steroid with C26 facing the heme with distance of 3.734 ${\AA}$ from the Fe were predominant.

The POSTECH Hand adopting coupled tendon driven technique with planar two fingers is developed. The hand is designed to emulate principal motions of the human hand which has two and three joints respectively. Its kinematic parameters are determined through a parameter optimizing technique to aim at improving the isotropy of fingertip motions with new criterion functions of design. For the control of the hand, tension and torque control algorithms are developed. Based on the virtual stiffness concept, we develop the stiffness control method of a grasped object with redundant finger mechnism and investigate experimentally.

Tendon driven method to drive one joint using two actuators is developed and implemented. While the method has advantages over conventional transmissions, it also has several drawbacks like tendon slack, elongation and endurability. In this paper, a compensation method of the intrinsic non-linearities of tendon is proposed to improve the performance of antagonistic tendon driven method. In this method, tendon tension measurement is prerequisite which is measured with strain gauge type tension sensor. The developed method is implemented on one link test bed with colocated and non-colocated position sensor.

An experimental study on the refrigerant-side pressure drop of slit fin-tube heat exchanger has been carried out. A comparison was made between the predictions of previously proposed empirical correlations and experimental data for the pressure drop on design conditions of condenser in micro-fin tube for R22 and its alternatives, R407C (R32/125/134a, 23/25/52 wt.％) and R410A (R32/125, 50/50 wt.％). Experiments were carried out under the conditions of inlet refrigerant temperature of 6$0^{\circ}C$ and mass fluxes varying from 150 to 250 kg/$m^2$s for R22, R407C and R410A. The inlet air conditions are dry bulb temperature of 35$^{\circ}C$, relative humidity of 40% and air velocity varying from 0.68 to 1.43 m/s. Experiments show that pressure drop for R410A and R407C were 17.8∼20.2％ and 5∼6.8％ lower than those of R22 respectively for the degree of subcooling of 5$^{\circ}C$. For the mass fluxes of 200∼250 kg/$m^2$s, the deviation between the experimental and predicted values for the pressure drop was less than $\pm$20％ for R22, R407C and R410A.
