<P>FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> ( x=0.1, 0.3, and 0.5) samples were prepared by solid state reaction method. The crystallographic structure and magnetic properties of the fabricated compounds were investigated by X-ray diffraction (XRD), superconducting quantum interference device (SQUID) magnetometer, and Mo¿ssbauer spectroscopy. The crystal structure is determined to be a cubic spinel with the space group of Fd-3m and the lattice constants <I>a</I> <SUB>0</SUB>= 9.998, 10.004, and 10.010 A¿ , respectively. The temperature dependence of magnetization, measured from 5 to 300 K, suggests that FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> (x=0.1, 0.3, and 0.5) samples show ferrimagnetic behavior. The decrease of Ne¿el temperature compared with FeCr<SUB>2</SUB>S<SUB>4</SUB> could be interpreted by weakening of the exchange interaction by substitution of nonmagnetic Al ions. Mo¿ssbauer spectra of FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> ( x= 0.1, 0.3, and 0.5) were obtained at various temperatures ranging from 4.2 to 300 K. Isomer shift values of the samples at various temperatures for FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> (x=0.1 , 0.3, and 0.5) were 0.50 ¿ ¿ ¿ 0.73 mm/s, relative to the Fe metal, which are consistent with the Fe<SUP>2+</SUP> valence state.</P>

To investigate psychopathoIogy and executive functions of attention deficit hyperactivity disorder (ADHD) children according to intelligence level, this study included 197 ADHD children who visited the outpatient department of neuropsychiatry of YeungNam University Medical Center, from July 2000 to June 2002. The children were divided into groups based on their intelligence levels. They were compared by the Personality Inventory for Children (PIC), Conncers' Continuous Performence Test (CPT), and Wisconsin Card Sorting Test (WCST). There were significant differences in PIC, on the subscales of verbal development, socialization and autism. In the CPT, there was no significant difference. In the WCST, there were significant differences in the total number of errors, the number of perseverative errors, the number of completed categories and the number of trials needed to complete the first category. Considering these results, the intelligence level of ADHD children is related to their disabilities and behavioral symptoms.Executive functions such as abstract thinking, categorization, working memory and flexibility had significant relationship to the intelligence levels of ADHD children. Therefore, the intelligence level of children with ADHD influences the higher executive functions of regulating attention and information processing rather than attentional functions and capacity alone.

<▼1><B>Abstract</B><P/></▼1><▼2><P>To overcome the limited feasibility of various refractory high-entropy alloys (HEAs) due to the presence of (i) very dense elements (W and Ta), (ii) costly elements (Hf and Ta), and (iii) oxidation prone elements (V) in them, Al<I>x</I>Cr<I>y</I>Mo<I>z</I>NbTiZr HEAs were prepared via arc-melting. Considering the critical nature of oxidation resistance in high-temperature applications, HEAs were characterized to form a combinatorial library of microstructural and oxidation behavior. Al<I>x</I>Cr<I>y</I>Mo<I>z</I>NbTiZr HEAs revealed multiphase microstructures consisting of intermetallic phases along with BCC matrices. Mass loss and porous microstructures were obtained in Mo-rich HEAs after oxidation at 1000 °C for 1 h. The presence of Al enhanced the oxidation resistance and developed a protective oxide layer on the HEAs. Al30Cr10-NTZ exhibited promising potential for use in high temperature applications, as it showed an oxidation time exponent of ∼0.5 and a dense and continuous oxide layer.</P></▼2>
