본 연구의 목적은 라디오 광고에서 정보원이 사용하는 언어 힘이 설득에 효과가 있는지를 관찰하고, 그 효과를 정보원의 성 그 자체의 효과와 비교해 봤을 때 과연 어떤 것이 설득을 결정하는 더 큰 요소인지를 알아보는 데 있다. 이 문제와 관련하여 선행 연구들은 일관성 없는 결괄르 보여주었다. 어떤 연구는 오디오 커뮤니케이션에서 언어 힘의 설득 효과는 학자의 성에 달려있다고 주장했고(Carli, 1990), 또 어ㅏ떤 연구는 오디오 커뮤니케이션에서 언어 힘의 설득 효과는 학자의 성에 관계없이 나타나는 굳건한 효과임을 주장했다(Holtgraves & Lasky, 1999; Erickson, Lind, Johnson, & O'Barr, 1978). 이에 본 연구는 라디오 광고에서 언어 힘과 정보원 성의 상호작용을 관찰함으로써 언어 힘의 설득 효과에 정보원의 성이 어떤 영향을 미치는지에 대한 실험적 증거를 제시하고자 했다. 실험 결과, 라디오 광고에서 정보원이 사용하는 언어 힘은 설득에 강한 효과가 있으며, 그 효과는 정보원 성의 영향을 받지 않는다는 것이 밝혀졌다. 이는 언어 힘의 지위 효과가 성의 지위 효과보다 더 강력하다는 것을 함축한다.

본 연구의 목적은 말더듬 성인을 대상으로 말더듬의 외현적 특성과 내면적 특성 간의 관련성을 조사하는 것이었다. 연구대상자는 말더듬 성인 10명이었으며, 각 대상자는 말더듬 중증도 검사-4(SSI-4), 전반적 말더듬 경험 평가-성인용(OASES-A), Erickson 의사소통태도검사-수정본(S-24)을 사용한 평가를 받았다. 말더듬의 외현적 특성은 SSI-4의 말더듬 빈도, 말더듬 지속시간, 신체적 부수행동 점수와 총 점수를 사용하였으며, 말더듬의 내면적 특성은 OASES-A의 네 개 하위 섹션(일반적인 정보, 말더듬에 대한 반응, 일상생활에서의 의사소통, 삶의 질) 점수와 총 점수, 그리고 S-24 점수를 사용하였다. 상관분석 결과, 말더듬의 외현적 특성 점수와 내면적 특성 점수 간 유의한 상관이 없는 것으로 나타났다. 반면, 말더듬의 내면적 특성을 반영하는 OASES-A 점수와 S-24 점수 사이에는 유의한 정적 상관이 나타났다. 본 연구 결과는 말더듬의 외현적 특성이 내면적 특성을 예측하기 어려우며 그 반대의 경우도 마찬가지라는 관점을 지지한다. 따라서 말더듬의 평가 및 치료 시 두 특성을 별도로 고려하는 것이 필요할 것이다.

Recently, increasing demand for teacher professional development and significant advances in information and communication technologies has led to a proliferation of online professional development. In spite of online professional development's popularity and advantages, research indicates that there is a concern of considerably high dropout rates of online learners. Therefore, to reduce the dropout rates of the learners, this paper is designed to help teachers identify professional development opportunities that are tailored to their needs as well as successfully complete these learning experiences. To achieve the purpose of the study, the paper explores the considerations for evaluating the characteristics of online learners and online professional development. Using these evaluations, this paper provides practical strategies for helping elementary and secondary education teachers successfully complete online professional development without dropping out an online course.

This keynote presentation covers the subject of intelligent systems development for monitoring and control in various NASA space applications. Similar intelligent systems technology also has applications in terrestrial commercial applications. Discussion will be given of the general approach of intelligent systems and description given of intelligent systems under prototype development for possible use in Space Shuttle Upgrade, in the Experimental Crew Return. Vehicle, and in free-flying space robotic cameras to provide autonomy to these spacecraft with flexible human intervention, if desired or needed. Development of intelligent system monitoring and control for regenerative life support subsystems such as NASA's human rated Bio-PLEX test facility is also described. A video showing two recent world's firsts in real-time vision-guided robotic arm and hand grasping of tumbling and translating complex shaped objects in micro-gravity will also be shown.

Long-lived Small Modular Reactors are being promoted as an innovative way of catering to emerging markets and isolated regions. They can be operated continuously for decades without requiring additional fuel. A novel configuration of long-lived reactor core employs a mixed neutron spectrum, providing an improvement in nonproliferation metrics and in safety characteristics. Starting with a base sodium reactor design, moderating material is inserted in outer core assemblies to modify the fast spectrum. The assemblies are shuffled once during core lifetime to ensure that every fuel rod is exposed to the thermalized spectrum. The Mixed Spectrum Reactor is able to maintain a core lifetime over two decades while ensuring the plutonium it breeds is below the weapon-grade limit at the fuel discharge. The main drawbacks of the design are higher front-end fuel cycle costs and a 58% increase in core volume, although it is alleviated to some extent by a 48% higher power output.

The work in this paper was motivated by [3], where Eschenbach and Li listed four 4 by 4 sign patterns, conjectured to be nilpotent sign patterns of nilpotence index at least 3. These sign patterns with no zero entries, called full sign patterns, are shown to be potentially nilpotent of nilpotence index 3. We also generalize these sign patterns of order 4 so that we provide classes of n by n sign patterns of nilpotence indices at least 3, if they are potentially nilpotent. Furthermore it is shown that if a full sign pattern A of order n has nilpotence index k with $2{\leq}k{\leq}n-1$, then sign pattern A has nilpotent realizations of nilpotence indices k, k + 1, $\ldots$, n. Hence, the four 4 by 4 sign patterns in [3, page 91] also allow nilpotent realizations of nilpotence index 4.

The Redshift Search Receiver (RSR) is a sensitive, ultra-wideband spectrometer that is being built at the University of Massachusetts as one of the facility instruments for the 50-m Large Millimeter Telescope (LMT). It consists of four receivers each covering the entire 3 mm window from 74 to 111 GHz instantaneously. The primary goal of the receiver is to detect multiple molecular lines in galaxies at any distance and uniquely determine the redshift, in particular dust-obscured star forming systems at high-z which are not easily accessible. I will present some results from commissioning of the RSR on the Five College Radio Astronomy Observatory 14-m telescope, and discuss the future of the receiver.

Data were collected from 110 preschoolers, 59 boys, 51 girls (ages 4-5) and their mothers. Peer competence was assessed by the Child Behavior Scale (Birsh & Ladd, 1998) and the Peer Rating Scale (Asher et al., 1979). Children's internal representations were measured by the MacArthur Story-Stem Battery (2004) and coded by the MacArthur Narrative Coding Manual (2004). Maternal parenting behaviors were observed during mother-child interaction at home and analyzed with the Teaching Strategies Rating Scale (Erickson, Sroufe, & Egeland, 1985). Data were analyzed by structural equation modeling analysis. Results confirmed the pathway from maternal parenting behaviors via children's internal representations to peer competence showing a significantly good model fit.

This paper will begin by describing osmosis and how reverse osmosis works. It will show how osmotic pressure affects reverse osmosis operations. It uill explain salt rejection, membrane flux, and recovery rates and the affect that salt built up has on membrane performance. It wil 1 explain the limitations of RO performance and why pretreatment is important. It will describe the two basic types of membrane, asymmetric and thin-film composite and explain the difference between these types plus compare cellulose acetate types to aromatic polyamide type membranes. It will discuss operating efficiences as it compares to feedwater pressure, concentration, temperature and pH. Finally, it will discuss the differences between tubular, plate and frame, hollow fiber and spiral wound element design. It will be a paper that talks about the basics of RO systems and should give a person who is unfamiliar with RO a basic introduction to this type of separation technology.

The substituted lithium ferrites combine useful ferromagnetic properties with high Curie temperature ranging from 55$0^{\circ}C$ to 85$0^{\circ}C$, [1] high saturation magnetization, [2] and low microwave dielectric loss.[3] Saturation magnetization of (Z $n_{1-x}$ F $e_{x}$)A[L $i_{0.5x}$F $e_{ 2-0.5x}$]$_{B}$ $O_4$ increased with zinc concentration, followed by a decrease at x = 0.7.[4] This is attributed to a dilution of the A-site with zinc which initially causes an increase in saturation magnetization due to the dominance of the B-site.
