ABSTRACT Sexual issues are common among the general population; therefore it is likely that clients suffer with them whether or not they are presenting issues. Because unresolved sexual issues may contribute to harm, counselors have an ethical obligation to ensure these issues are addressed during therapy. Yet, many fail to do so for a variety of reasons. Because clinical supervisors are in a unique position to nurture and mentor novice counselors, their influence is salient to this issue. Although some research has been done to address this issue, results are inconclusive and somewhat contradictory. This study attempts to fill in the missing data and to address some of the discrepancies by exploring how counselors perceive addressing sexual issues, identifying some of the influencing factors that allow this issue to persist, and exploring how clinical supervisors can be supportive. Sixty-three mental health professionals from the state of Florida participated in a survey where they were asked about both their experiences as clinicians and as interns under supervision. Both quantitative and qualitative data were collected, and descriptive statistics, as well as chi-square test of independence were calculated. The degree to which counselors reported being very comfortable with addressing clients' sexual issues did not align with the reported frequency of initiation of the topic nor the reported levels of discomfort on specific sexual topics. Comfort levels related to discussing sexual issues were found to be positively associated with frequency of initiation, and in couples cases, female counselors raised the topic significantly more often than male counselors. Other findings are analyzed and discussed, conclusions are drawn, and recommendations for future study and implications for the field are included.

Smart grid technologies are starting to be the future of electric power systems. These systems are giving the utilities detailed information about their systems in real time. One of the most challenging things of implementing smart grid applications is employing the communications into the systems. Understanding the available communications can help ease the transition to these smart grid applications. Many of the utility personnel are spending too much time trying to figure out which communication is better for their application or applications. So this thesis presents the different communication types available with discussing the different attributes in which these communication types are going to offer to the utility. Then these communication types are looked such that utilities can quickly understand how to approach the difficult task of obtaining the information from the different smart grid applications by the use of different communication options.

Classroom observation - particularly the post observation conference - is one of the most important aspects of staff development. The headmaster should create the climate in which the teacher has scope for self-development. During and especially after the class observation, it is imperative that the headmaster provides a restful, relaxed atmosphere, particularly for the post observation conference. This conference is of the utmost importance, as it provides feedback to the teacher on how another knowledgeable person experiences his presentation of a lesson. This research initially focused on staff development, what it entails and how it can be utilized by headmasters in schools. A closer look was taken at the post observation conference after a classroom observation, a questionnaire was distributed among the headmasters of various schools and the paper closes with recommendations and definite guidelines to headmasters. It is important for the school to be a pleasant working environment, where mutual respect and trust should exist. In such a climate, it is possible for the headmaster, during the post observation conference, to make recommendations and give advice without causing any hurt-feelings, enabling the teacher to develop professionally. A staff development plan with clear goals and target dates should ultimately be compiled. / Skripsie (MEd (Onderwysbestuur))--PU vir CHO, 1996

This thesis investigates the relationships between performance, workload, and situation awareness at varying levels of automation. The relationships observed in this study are compared to a description put forth to formalize the conventional interpretation of the trade-off between the benefits of automation during routine operation and the costs under conditions of automation failure. The original work stipulated that this “routine-failure trade-off” is likely a simplification affected by contextual factors. This work therefore aimed to i) provide empirical evidence to support or refute the trade-off and ii) to identify possible extenuating factors. The results generally supported the routine-failure trade-off, and considered in light of the functional structure of the task suggested that the relationships between goals and individual functions specific to a given task seem to affect the overall costs and benefits of automation through the mechanism of selective reliance. Further work is required to validate the findings of this study.

Despite increased awareness of threats against Critical Infrastructure (CI), securing of Supervisory Control and Data Acquisition (SCADA) systems remains incomplete. The majority of research focuses on preventative measures such as improving communication protocols and implementing security policies. New attempts are being made to use commercial Intrusion Detection System (IDS) software to protect SCADA systems. These have limited effectiveness because the ability to detect specific threats requires the context of the SCADA system. SCADA context is defined as any information that can be used to characterise the current status and function of the SCADA system. In this thesis the standard IDS model will be used with the varying SCADA data sources to provide SCADA context to a signature and anomaly detection engine. A novel addition to enhance the IDS model will be to use the SCADA data sources to simulate the remote SCADA site. The data resulting from the simulation is used by the IDS to make behavioural comparison between the real and simulated SCADA site. To evaluate the enhanced IDS model the specific context of a water and wastewater system is used to develop a prototype. Using this context it was found that the inflow between sites has similar diurnal characteristic to network traffic. This introduced the idea of using inflow data to detect abnormal behaviour for a remote wastewater site. Several experiments are proposed to validate the prototype using data from a real SCADA site. Initial results show good promise for detecting abnormal behaviour and specific threats against water and wastewater SCADA systems.

Ο στόχος της παρούσας διπλωματικής εργασίας είναι ο έλεγχος και αποκατάσταση της θερμοκρασίας και της υγρασίας από απόσταση σε ένα χώρο ο οποίος απαιτεί συγκεκριμένες τιμές των δύο παραπάνω μεγεθών. Ένας τέτοιος χώρος μπορεί να είναι μια αίθουσα χειρουργείου ή μια μονάδα εντατικής θεραπείας. Ανάλογα με τις επιθυμητές θερμοκρασίες που έχουν τεθεί, ενεργοποιούνται οι βάνες του θερμαντικού ή του ψυκτικού στοιχείου. Όταν η υγρασία του χώρου είναι κατώτερη της επιθυμητής, ενεργοποιείται η τρίοδος βάνα ατμού. Όταν η υγρασία του χώρου είναι υψηλότερη της επιθυμητής ενεργοποιείται η τρίοδος βάνα του ψυκτικού στοιχείου για επιπλέον ψύξη (αφύγρανση) και παράλληλα, αν χρειαστεί ενεργοποιεί και την τρίοδο βάνα του θερμαντικού στοιχείου για να διατηρήσει τη θερμοκρασία του χώρου στα επιθυμητά επίπεδα. Όλα αυτά υλοποιούνται με τη βοήθεια του PLC S7 300 όσο αφορά το λειτουργικό μέρος, της μονάδας CP 343-1 Lean για την επικοινωνία της εγκατάστασης από απόσταση μέσω ethernet, το LabVIEW 9.0 για την υλοποίηση του SCADA(Supervisory Control and Data Acquisition) και τέλος ο OPC SERVER της National instrument για την επικοινωνία του PLC S7 300 με το LabVIEW 9.0. / The scope of this thesis is the control and restoration of temperature and humidity from distance in environments which demand precise values of these two measurements. Such an environment can be an Operating Room or an Intensive Care Unit. The valves of the heating or the cooling element are activated according to the desired temperature. When room humidity is below the desired one, the dew three-port valve is activated. On the other hand when humidity is above the desired level the three-port valve of the cooling element is activated for further cooling (dehydration) and at the same time, if needed, it activates the three-port valve of the heating element to maintain the room temperature at the desired level. This is possible with the use of PLC S7 300, when it comes to the functional part, the CP 343-1 Lean unit for the distant communication of the installation through the use of Ethernet, the LabVIEW 9.0 for the implementation of the SCADA(Supervisory Control and Data Acquisition) and the OPC SERVER of the National Instrument for the communication of the PLC S7 300 with LabVIEW 9.0.

Violence in the work environment is growing; being nursing is one of the professions in health more likely to suffer it. Throughout this research, it was chosen to investigate violence in the work of nursing in hemodialysis service. The objectives of this study consisted in identifying the determinants of violence at work recognized by the nursing staff of hemodialysis service and know the strategies adopted concerning the issue. It is a qualitative research which had as study environment a service of hemodialysis. Inclusion criteria were: being a nurse, technician or auxiliary nurse, to be a current employee and be working at the period of data collection. The focus group technique was chosen to obtain the data, which occurred in June 2010, according to the ethical guidelines for research involving humans. The data were treated according to theme analysis, being organized and discussed through three theme lines: the understanding given to violence in work environment, workplace violence in the space of chronic kidney disease when the patient is the assailant and, finally, the strategies used by nursing staff to face violence at work in the service of hemodialysis. Eight nursing staff participated in the study. It was highlighted that the concept of workplace violence is complex, depending on individual conceptions of each worker. Violence was described as quotidian in the context of chronic illnesses, being the verbal form the main one in these environments. The patient on hemodialysis was highlighted as the main agent of violence in this context, being influenced by chronic disease status of relations with the nursing staff, due to personal characteristics of the patient and, finally, as a matter of everyday life. Participants stated that violence causes pain and illness in the team, adopting the following strategies: tolerance for violence by the health condition of the patient; giving in not to be attacked, take a strong position and get away from the offender patient. It can be said that violence in nursing work is present in hemodialysis services studied and, with this study, awoke to taking actions that seek ways to face this reality. In this sense, it is understood that these results should not be taken as absolute and direct to the paths that can be investigated, recommending the expansion of the discussions about violence at work in other hemodialysis services. / A violência no trabalho vem crescendo, sendo a enfermagem uma das profissões da área da saúde mais propensas a sofrê-la. Neste estudo, optou-se por investigar a violência no trabalho de enfermagem em um serviço de hemodiálise. Os objetivos do estudo consistiram em identificar os fatores determinantes da violência no trabalho reconhecidas pelos trabalhadores de enfermagem de um serviço de hemodiálise e conhecer as estratégias adotadas frente à questão. Trata-se de uma pesquisa qualitativa que teve como ambiente de estudo um serviço de hemodiálise. Os critérios de inclusão foram: ser enfermeiro, técnico ou auxiliar de enfermagem, estar efetivado e trabalhando no serviço no período de coleta dos dados. O grupo focal foi a técnica escolhida para a obtenção dos dados, que ocorreu em junho de 2010, conforme os preceitos éticos para pesquisas com seres humanos. Os dados receberam tratamento conforme a análise temática, sendo organizados e discutidos em torno de três eixos temáticos: o entendimento dado a violência no trabalho; violência no trabalho no espaço da doença renal crônica quando o paciente é o agressor; e, por último, as estratégias utilizadas pelos trabalhadores de enfermagem frente à violência no trabalho no serviço de hemodiálise. Participaram do estudo oito trabalhadores de enfermagem. Evidenciou-se que o conceito de violência no trabalho é complexo, dependendo de concepções individuais de cada trabalhador. A violência foi descrita como cotidiana no contexto de adoecimento crônico, sendo a verbal a principal forma nestes ambientes. O paciente em hemodiálise foi destacado como principal agente de violência neste contexto, sofrendo influência da situação de doença crônica pelas relações com os trabalhadores de enfermagem, por características pessoais do paciente e, por último, por questões do dia a dia. Os participantes afirmaram que a violência causa sofrimento e adoecimento na equipe e adotam como estratégias: tolerância à violência pela condição de saúde do paciente; contornar e ceder para não ser agredido; adotar um posicionamento firme e se afastar do paciente agressor. Pode-se afirmar que a violência no trabalho da enfermagem está presente no serviço de hemodiálise estudado e, com a realização deste estudo, despertou-se para a tomada de ações que busquem formas para o enfrentamento desta realidade. Neste sentido, entende-se que estes resultados não devem ser tomados como absolutos e direcionam-se aos caminhos que podem ser investigados, recomendando-se a ampliação das discussões acerca da violência no trabalho em outros serviços de hemodiálise.

However, the pipelines suffer deterioration in their walls caused by several factors which may cause loss of fluids to the environment, justifying the investment in techniques and methods of leak detection to minimize fluid loss and environmental damage. This work presents the development of a supervisory module in order to inform to the operator the leakage in the pipeline monitored in the shortest time possible, in order that the operator log procedure that entails the end of the leak. This module is a component of a system designed to detect leaks in oil pipelines using sonic technology, wavelets and neural networks. The plant used in the development and testing of the module presented here was the system of tanks of LAMP, and its LAN, as monitoring network. The proposal consists of, basically, two stages. Initially, assess the performance of the communication infrastructure of the supervisory module. Later, simulate leaks so that the DSP sends information to the supervisory performs the calculation of the location of leaks and indicate to which sensor the leak is closer, and using the system of tanks of LAMP, capture the pressure in the pipeline monitored by piezoresistive sensors, this information being processed by the DSP and sent to the supervisory to be presented to the user in real time / O transporte de fluidos atrav?s de tubula??es ? utilizado na ind?stria petrol?fera, sendo os dutos um elo importante na log?stica de escoamento de fluidos.
