Assessment Of Providing In Class, Hands On, Activities To Virginia Tech's First Year Engineering Students

Historically, engineering has been a practical outgrowth of the need to solve physical problems. Engineering education was initially based in practical laboratory and shop experiences, as well as traditional instruction in science and mathematics. Following World War II, engineering education in the United States began emphasizing theoretical sciences and mathematics. Though a justified response at the time, this approach has evolved to one of less and less practical instruction. Today, there is a strong need to supplement traditional teaching with activities that give practical meaning to the equations presented in the lecture. To partially address this problem, we presented several hands-on collaborative experiences in eight of the 36 Introduction to Engineering (EF1015) lecture classes during the 2000 fall semester. This paper will discuss the impact of these activities on student learning and perception of learning. A questionnaire to assess student perceptions of learning was given at midsemester and at the end of the semester to eight hands-on (HO) sections and ten traditional (TR) sections. We first compare HO versus TR mid-semester responses and final responses to see if there is any difference in the students’ perception of their learning. We then compare HO mid-semester perceptions versus HO end semester perceptions to see if hands-on activities were more beneficial to latter subjects. The results of these surveys and comparisons are presented as are our conclusions concerning using hands-on activities in class. Background Virginia Tech requires all first semester engineering students to take Introduction to Engineering I (EF 1015); a two-credit course designed to introduce the profession and to develop problem-solving skills. The instruction of engineering has become more theoretical and our students less hands-on over the last 50 years. It is entirely possible for an engineering student to graduate without ever having built or analyzed an engineering object. A fall 2000 survey of Tech’s incoming freshman students showed that they come to engineering having very little experience in practical, technical, matters. The survey showed that: • One half do not know the location of their home’s breaker box • One half have not changed the oil in a car P ge 618.1
Behind the Knowledge and Attitude: Female Adolescent in Looking at Physical Appearance Change during Puberty at SMPN 1 Telaga Biru Gorontalo

As a period of life, the adolescence is an important stage that a person must go through before he reaches adulthood. During adolescence, many changes occur both biologically, psychologically and socially. Generally, the process of physical change occurs faster than mental maturation. The changes in physical appearance that occur in adolescents can cause anxiety and awkwardness for adolescents because they require them to adjust to the changes that occur. This study aimed to analyze the relationship between knowledge and attitudes of young women in preparing for physical appearance changes during puberty in SMP Negeri 1 Telaga Biru, Gorontalo District, Gorontalo Province, Indonesia. This type of research is a quantitative study with a cross sectional approach. The population in this study were all of the 163 female junior high school students of SMP Negeri 1 Telaga Biru 1 in Gorontalo. The sampling technique used stratified random sampling on grade VII to IX students. The obtained samples were 54 students. Data processing was analyzed using chi square test. Based on the research results, it was found that the relationship between the knowledge of young women in dealing with physical changes at puberty was p value = 0.009 < 0.05. Second, there is a relationship between the attitudes of young women in dealing with physical changes at puberty with the results of the chi square test showing the p value = 0.007 < 0.05. The conclusion of this study is that there is a relationship between adolescent knowledge in dealing with physical changes at puberty and there is a relationship between adolescent attitudes in dealing with physical changes at puberty. Researchers expect that in dealing with changes during puberty, adolescents must equip themselves with knowledge and have a positive attitude.
Conceptual Model to Explain, Predict, and Improve User Acceptance of Driverless Podlike Vehicles

This paper presents a synthesis of existing empirical acceptance studies on automated driving and scientific literature on technology acceptance. The objective of the study was to study user acceptance of SAE Level 4 vehicles or driverless podlike vehicles without a steering wheel and pedals that operated within the constraints of dedicated infrastructure. The review indicates that previous acceptance studies on automated driving are skewed toward car users and thus create a need for targeted acceptance studies, including users of public transport. For obvious reasons, previous studies targeted respondents who had not experienced driverless vehicles. As driverless vehicles are currently being demonstrated in pilot projects, their acceptance by users inside and outside such vehicles can now be investigated. Addressing the multidimensional nature of acceptance, a conceptual model that integrates a holistic and comprehensive set of variables to explain, predict, and improve user acceptance of driverless vehicles was developed. The model linked two dominant models from the technology acceptance management literature, the unified theory of acceptance and use of technology and the pleasure–arousal–dominance framework, with a number of external variables that were divided into system-specific, user, and contextual characteristics.
Integrated risk assessment for cultural heritage sites: a holistic support tool for decision-making

The majority of the studies related to risk or the risk management of cultural heritage focus on natural hazards and armed conflict. However, cultural heritage sites face new and numerous threats that jeopardize their conservation. Currently, risk assessment focuses on specific cases of potential damage and hazards, and fails to take into account the interdependence between risk factors, causes, and management. This situation is compounded by the fact that the field of cultural heritage does not tend to operate a “culture of assessment” in which decisions are taken in an informed way. For this reason, the aim of this research is to propose an integrated management support tool for the identification and prioritization of risk factors in the conservation of cultural heritage sites. In order to achieve this objective, the research approaches the conception of risk used in the cultural heritage context, and offers a new definition. This research highlights the importance of conservation in terms of the preservation of values. This work adds to the field by explaining how these values can be merged with a “value-oriented approach” in decision-making. In managerial terms, this work also refers to the international standard for risk management and explains how to apply such concepts to the context of cultural heritage. This research constructs a holistic approach and defines the cultural heritage site as a complex system. From this perspective, this study proposes multiple-criteria methods for the realization of an integrated risk assessment for cultural heritage sites, suggesting the application of a rationale behind the Analytic Hierarchy Process (AHP) and the Analytic Network Process (ANP) as tools for the integration of elements in risk management. In this sense, the methodology allows for links of interdependence to be established among the varying potential threats. It also provides support for decision-making in terms of the conservation of cultural heritage sites. Finally, this work concludes by indicating the benefits and challenges found in the use of multiple-criteria methods for the prioritizing of actions in risk management
Evaluation of Patients' Health Literacy and Nursing Care Satisfaction Levels According to Some Descriptive Characteristics

Aim: This descriptive Study aimed to determine the relationship between the level of health literacy and the level of nursing care satisfaction in patients and to evaluate it according to some descriptive characteristics. Materials and Methods: This Study was conducted with 230 patients who were hospitalized in the internal medicine and general surgery inpatient ward of a city hospital and accepted to participate in the Study. The Newcastle Nursing Care Satisfaction Scale (NNCSS) and the Health Literacy Scale (HLS) were used to collect data. Results: The NNCSS mean scores of the men, of the employees, those who hospitalized in that hospital before, those who use computers or smart phones, and those who use social media accounts were high (p<0.05). When the patients’ Health Literacy Scale mean scores were evaluated, a statistically significant difference was found in terms of education status, employment status, income status, and those who searched for their disease on the internet(p<0.05). There was positive and moderate correlation between the NNCSS and HLS total scores (r=0.507, p<0.001). Conclusion: It was found that as the level of health literacy increased, nursing care satisfaction increased, and the level of health literacy and patient care satisfaction changed according to some descriptive characteristics. It is recommended that nurses should be aware of the relationship between care satisfaction and health literacy levels and the factors that reduce it, and plan their interventions about the factors that can change this. Exhibitor Consent: We conducted according to the ethics guidelines set out in the Declaration of Helsinki. All the patients participating in the study were informed about the study, their written/verbal consents were taken, and they were also informed that they could leave the study at any time.
Chitin Nanofibril-Nanolignin Complexes as Carriers of Functional Molecules for Skin Contact Applications

Chitin nanofibrils (CN) and nanolignin (NL) were used to embed active molecules, such as vitamin E, sodium ascorbyl phosphate, lutein, nicotinamide and glycyrrhetinic acid (derived from licorice), in the design of antimicrobial, anti-inflammatory and antioxidant nanostructured chitin nanofibrils–nanolignin (CN-NL) complexes for skin contact products, thus forming CN-NL/M complexes, where M indicates the embedded functional molecule. Nano-silver was also embedded in CN-NL complexes or on chitin nanofibrils to exploit its well-known antimicrobial activity. A powdery product suitable for application was finally obtained by spray-drying the complexes co-formulated with poly(ethylene glycol). The structure and morphology of the complexes was studied using infrared spectroscopy and field emission scanning electron microscopy, while their thermal stability was investigated via thermo-gravimetry. The latter provided criteria for evaluating the suitability of the obtained complexes for subsequent demanding industrial processing, such as, for instance, incorporation into bio-based thermoplastic polymers through conventional melt extrusion. In vitro tests were carried out at different concentrations to assess skin compatibility. The obtained results provided a physical–chemical, morphological and cytocompatibility knowledge platform for the correct selection and further development of such nanomaterials, allowing them to be applied in different products. In particular, chitin nanofibrils and the CN-NL complex containing glycyrrhetinic acid can combine excellent thermal stability and skin compatibility to provide a nanostructured system potentially suitable for industrial applications.
Prognostic Value of the Ki67 Proliferation Index, CD10 and MUM1 in Follicular Lymphoma

Background/Purpose: Follicular lymphoma (FL) is an indolent lymphoma and is associated with a long survival time. However, there are patients who had an early progression after standard therapy. Our aim was to analyze the prognostic value of Ki67, CD10 and MUM1 expression in FL. Methods: Immunohistochemical staining for Ki67, CD10 and MUM1 was performed on formalin-fixed paraffin-embedded biopsy tissues from 27 patients with FL. Patients were grouped according to the levels of the Ki67 proliferation index (PI). Survival times were analyzed and the cut-off value for Ki67 PI was determined. The patients were also divided into groups according to the presence of CD10, MUM1and MUM1 positive/CD10 negative. Results: Ki-67 PI levels were as follows: ≤ 20% in 14 patients, 21-40% in 6 patients, 41-60% in 4 patients, > 60% in 3 patients. A cut-off value of 60% revealed significantly different survival rates. OS, PFS in the Ki67 > 60% group decreased significantly for 5 years, and the difference was statistically significant (37.5% vs. 100%, p = 0.000; 0% vs. 66.7%, p = 0.016; respectively). The CD10 negative group had a less favorable outcome than the positive group in the OS rate at 5 years (72% vs. 100%, p = 0.049) and the PFS rate at 5 years (25.3% vs. 72.6%, p = 0.017). OS and PFS in the group with MUM1 positive/CD10 negative decreased significantly for 5 years than in the group without MUM1 positive/CD10 negative (4.7% vs. 100%, p = 0.002; 0% vs. 66.4%, p = 0.006; respectively). Conclusion: Ki67 > 60%, CD10 negative, MUM1 positive/ CD10 negative are poor prognostic factors in FL.
Augmenting Vehicle Localization with Visual Context

Vehicle self-localization, the ability of a vehicle to determine its own location, is vital for many aspects of Intelligent Transportation Systems (ITS) and telematics where it is often a building block in a more complex system. Navigation systems are perhaps the most obvious example, requiring knowledge of the vehicle’s location on a map to calculate a route to a desired destination. Other pervasive examples are the monitoring of vehicle fleets for tracking shipments or dispatching emergency vehicles, and in public transit systems to inform riders of time-of-arrival thereby assisting trip planning. These system often depend on Global Positioning System (GPS) technology to provide vehicle localization information; however, GPS is challenged in urban environments where satellite visibility and multipath conditions are common. Vehicle localization is made more robust to these issues through augmentation of GPS-based localization with complementary sensors, thereby improving the performance and reliability of systems that depend on localization information. This thesis investigates the augmentation of vehicle localization systems with visual context. Positioning the vehicle with respect to objects in its surrounding environment in addition to using GPS constraints the possible vehicle locations, to provide improved localization accuracy compared to a system relying solely on GPS. A modular system architecture based on Bayesian filtering is proposed in this thesis that enables existing localization systems to be augmented by visual context while maintaining their existing capabilities. It is shown in this thesis that localization errors caused by GPS signal multipath can be reduced by positioning the vehicle with respect to visually-detected intersection road markings. This error reduction is achieved when the identities of the detected road marking and the road being driven are known a priori. It is further shown how to generalize the approach to the situation when the identities of these parameters are unknown. In this situation, it is found that the addition of visual context to the vehicle localization system reduces the ambiguity of iden-
Radio-Medicine and Public Health in Rural Ghana

Radio is know-how that comes with low manufacturing costs, and low infrastructure costs and its marginal cost of distribution is very low which is close to zero. This study was conducted to examine the rate at which radios advertise medical services and products; the factors that promote the patronage of radio-medicine and evaluate the effects of radio-medicine on people who patronize it. The study took place at Agogo by interviewing 50 people belonging to 10 different professional groups as follows: Farmers, Drivers, shopkeepers, tailors/seamstresses, teachers, hairdressers, barbers, market women, students and the unemployed. Through SPSS, the data was analyzed and the result indicated that 44.0% listen to radio once a day, 14.0% listen every hour, and 42.0% listen all day. On the reasons for patronizing radio-medicine, 24% bought per testimonies shared from others, 12% said it is easy to patronize, 12.0% do that for affordability and effectiveness, 8.0% said it is good, 4.0% were highly convinced by suppliers, 4.0% patronized because there are no side effects, 12.0% were for just trials, 10.0% said there is no time to go to the hospital, 8.0% did so because they had minor conditions and 6.0% patronized for first aid and relieve of symptoms. In addition, 68.0% agreed that the medicine worked for them as expected but 32.0% agreed that the medicine did not work as expected. It was concluded that most people listen to radio all day and most of them participate, in medicines advertised on the radio, because of testimonies shared by others. Even-though majority of the respondents thought they could be affected they did not care about it. Recommendations have been made to the Ministry of Health to regulate radio-medicine and its patronage and also for further research by research institutions.
Systematic paleontology, acritarch biostratigraphy, and δ13C chemostratigraphy of the early Ediacaran Krol A Formation, Lesser Himalaya, northern India

Acritarch biostratigraphic and δ13C chemostratigraphic data from the Krol A Formation in the Solan area (Lesser Himalaya, northern India) are integrated to aid inter-basinal correlation of early–middle Ediacaran strata. We identified a prominent negative δ13C excursion (likely equivalent to EN2 in the lower Doushantuo Formation in the Yangtze Gorges area of South China), over a dozen species of acanthomorphs (including two new species—Cavaspina tiwariae Xiao n. sp., Dictyotidium grazhdankinii Xiao n. sp.), and numerous other microfossils from an interval in the Krol A Formation. Most microfossil taxa from the Krol A and the underlying Infra-Krol formations are also present in the Doushantuo Formation. Infra-Krol acanthomorphs support a correlation with the earliest Doushantuo biozone: the Appendisphaera grandis-Weissiella grandistella-Tianzhushania spinosa Assemblage Zone. Krol A microfossils indicate a correlation with the second or (more likely, when δ13C data are considered) the third biozone in the lower Doushantuo Formation (i.e., the Tanarium tuberosum-Schizofusa zangwenlongii or Tanarium conoideum-Cavaspina basiconica Assemblage Zone). The association of acanthomorphs with EN2 in the Krol Formation fills a critical gap in South China where chert nodules, and thus acanthomorphs, are rare in the EN2 interval. Like many other Ediacaran acanthomorphs assemblages, Krol A and Doushantuo acanthomorphs are distributed in low paleolatitudes, and they may represent a distinct paleobiogeographic province in east Gondwana. The Indian data affirm the stratigraphic significance of acanthomorphs and δ13C, clarify key issues of lower Ediacaran bio- and chemostratigraphic correlation, and strengthen the basis for the study of Ediacaran eukaryote evolution and paleobiogeography.

USE OF RAY TRACING MODELING IN SHALLOW WATER ACOUSTIC SOURCE LOCALIZATION COMBINED WITH MATCHED-FIELD PROCESSING TECHNIQUES

ABSTRACT. Underwater source localization based on acoustic modeling has been a subject of intensive research since a long time. In the case of shallow water scenarios (which are characterized by multilayered bottoms) normal-mode based acoustic propagation models are often combined with Matched-Field Processing techniques in order to provide accurate estimates of both source range and depth. This work discusses the use of a ray tracing model for source localization. Accurate predictions of the acoustic field are obtained by replacing the multilayered bottom with an equivalent (single-layer) bottom, to be used by the ray model, where the properties of the equivalent bottom are obtained through parameter optimization based on the comparison between rays (single-layer) andmodes (multilayer) predictions. The accuracy of this approach is tested using data from an experiment performed by the former Undersea Research Centre of the Supreme Allied Commander Atlantic (SACLANT) in the north of the Elba Island, near the Italian coast. The results indicate that the proposed approach allows a ray model to locate an stationary source with the same accuracy as the one achieved with a normal mode model. Keywords: underwater acoustic modeling, ray-based models, normal mode models. RESUMO. A localizacao de fontes submarinas por meio de modelos de propagacao acustica e um antigo problema de grande interesse cientifico. Em cenarios de aguas rasas, que se caracterizam normalmente por fundos com complexos sistemas multicamadas, os modelos de propagacao baseados na teoria de modos normais sao geralmente combinados com tecnicas de Processamento por Campo Casado para produzirem estimativas acuradas da distância e profundidade de uma fonte acustica. O trabalho aqui apresentado propoe a utilizacao de um modelo de tracado de raios no problema da localizacao. De maneira a produzir estimativas acuradas do campo acustico, o modelo de raios recorre a um modelo equivalente do fundo, baseado numa escolha otima de parâmetros, os quais sao obtidos por meio da comparacao entre as previsoes geradas por um modelo de raios (que considera um ambiente de camada unica) e as geradas por um modelo de modos (que considera um ambiente original multicamadas). A acuracia da metodologia e verificada por meio de dados adquiridos ao norte da Ilha de Elba (nas proximidades da costa italiana), oriundos de um experimento realizado pelo entao Undersea Research Centre of the Supreme Allied Commander Atlantic (SACLANT). Os resultados alcancados indicam que a metodogia aqui proposta demonstra ser possivel um modelo de raios para localizar uma fonte estatica com acuracia comparavel aquela tradicionalmente obtida por um modelo de modos normais. Palavras-chave: modelagem acustica submarina, modelos de raios, modelos de modos normais.
