The new trends in main spindle design of Machining Center are focused on high-speed, high-precision and high-stiffness. As a main spindle bearing, the angular-contact ball bearing is well used. A rolling bearing is usually only a small part of a larger mechanical system, but its performance can have a great influence on the functioning of the whole machine. This work is about fatigue life tester design and monitoring of defected rolling-element bearings. The major work is done via experiments and the vibration signal is analysised by means of frequency spectrum technique. By analyzing the frequency spectrum, it is possible to view the condition of the bearings.

An analysis of nursing activities in a in-patient ward and its management was observed in order to assess necessary number of nursing hands and find out reasonable work management with them. The study was performed with two wards of St. Mary′s Hospital, Catholic Medical Center, for the period from July to December 1970. The results and conclusions were as the following 1. The role of the nurses are determined by doctor′s order in 57.7% in kind, 80.0% in amount. and by nurses decision 20.0% in amount. 2. Works related to patient care are found to be 20.6% in the internal medicine ward and 20.4% in the surgical ward while works related to treatment are 4.7% in the former and 27.2% in the letter. Medication occupies 40.0% in the internal medical ward while 26.6% in the surgery ward, and observation occupies 34.7% in the former while 25.8% in the letter. These can be said to reflect characteristic differences bet ween the two wards. 3. When nursing functions were evaluated by importance "A" level in the amount of works to be done occupied 67.6% in the surgical ward and 62.8% in the internal medical ward. In the kind of the important works, "B"level is found to be most frequent with 50% while "A"level 43%. When evaluated by difficulty, "B"level was found to be most frequent in amount in both internal medicine and surgical wards (52.6%, 38.2%). 4. Works needing professional knowledge and skills occupied 92% in the both wards while unprofessional works 2.8% and 4.2% respectively. There are indications, however, that unprofessional works have an increasing tendency. 5. When evaluated by the amount of works, the surgical ward has 11 nurses less and the internal medicine ward 3 nurses less then the necessary number of nursing staffs. There are shortage of 12 and 6 nurses respectively when evaluated by the number of patients and 18 nurses in the both wards when evaluated by the medical regulations of the Government. 6. The ratio of the nursing staff to patient was found to be 1:11.5, 1:23.0 and 1:34.5 in the morning, evening and night turn in the surgical ward. In the medical word the ratio was 1:9.4, 1:22.0 and 1:33.0. 7. The deficiency of necessary equipment and tension accompanying management of those equipment were found to lower the effective functioning of the head nurse who is a junior manager of the ward. They also consume much of the time and energy of the nurses at work who are over burdened in most of the cases. 8. The high rate of the number of nurses who leave the job impairs the functioning of team work which is considered to be most important in the effective performance of nursing activities and thus contributes to lower the efficiency of nursing functions.

The purpose of this Study is to theoretically discuss the Family Business. Family Business means a business that is owned and managed by one or more family members. Family Businesses are seen as an avenue to achieve economic security, as motivations for a productive society, and as a method for individuals to receive a monetary return for their talents and initiative. The presence of family business as a predominant business structure in the all of country's economy and their association economic contributions have been documented elsewhere. The overall objectives of this study are to introduce in the Home economics and Home Management field what the Family Business is, concretely to identify the definition of Family Business and related concepts-Home Based Business & Home Based work-, to study the interface of family and business functions within a single family. This study is to examine a clear understanding of the relationship between family functioning and business viability in families who own and operate businesses. Such understanding will be helpful in enhancing the stability and security of families who own and operate business and in developing policies and programs that foster Family Business and assist in their contributions to community and economic development. Also to understand the family and business environments and their interaction can enhance the opportunities and satisfactions for family members who are involved in business together. Results from this study will allow researchers a unique view of the Family business management and will contribute to individual and group well-being in both family and work settings.

Vehicular Ad Hoc Networks (VANETs) are self-configuring networks where the nodes are vehicles equipped with wireless communication technologies. In such networks, limitation of signal coverage and fast topology changes impose difficulties to the proper functioning of the routing protocols. Traditional Mobile Ad Hoc Networks (MANET) routing protocols lose their performance, when communicating between vehicles, compromising information exchange. Obviously, most applications critically rely on routing protocols. Thus, in this work, we propose a methodology for investigating the performance of well-established protocols for MANETs in the VANET arena and, at the same time, we introduce a routing protocol, called Genetic Network Protocol (G-NET). It is based in part on Dynamic Source Routing Protocol (DSR) and on the use of Genetic Algorithms (GAs) for maintenance and route optimization. As G-NET update routes periodically, this work investigates its performance compared to DSR and Ad Hoc on demand Distance Vector (AODV). For more realistic simulation of vehicle movement in urban environments, an analysis was performed by using the VanetMobiSim mobility generator and the Network Simulator (NS-3). Experiments were conducted with different number of vehicles and the results show that, despite the increased routing overhead with respect to DSR, G-NET is better than AODV and provides comparable data delivery rate to the other protocols in the analyzed scenarios.

The article highlights the European experience of innovative educational technologies of training management specialists. Based on existing strategies, relevant in the European educational space, the introduction of regulatory elements to maintain a balance between the traditional and innovative format of the educational process, which is typical for the Ukrainian education system is proposed. The article aims to single out educational and technological innovations into a separate cluster of managerial training at different levels in the context of the principles of the modern synergetic sociocultural paradigm. The main objectives of the work are to develop settings to ensure the effective functioning of innovative educational technologies. Among the synergetic principles of educational technologies, providing the formation of necessary competencies of future managers, are: self-organization, interdisciplinarity, nonlinearity, individuality, and technologization. The methods used in the scientific study can be attributed to the group of scientific synergetic methodology. So, the training of specialists in management, implemented in the European practice assumes the use of new educational strategies. These technologies provide both the necessary skills of different levels (hard-soft-digital skills) and the observance of value components (solidarity, ethics, inclusiveness, openness).

Objectives : The purpose of this pilot study was to investigate the potential clinical benefits a single group session of cognitive behavioral therapy in the treatment of patients with panic disorder. Methods : The study participants were 18 patients (14 males, 4 females; mean age=38.9 years), all of whom were assessed as meeting the DSM-IV-TR criteria for panic disorder. All participants attended one two-hour session of structured group cognitive behavioral therapy (CBT). Clinical symptoms was assessed before and eight weeks after the single therapy session using the Panic Disorder Severity Scale (PDSS). Results : Eight weeks after a single session of group CBT significant improvements were found in panic attack frequency, distress during panic attacks, severity of anticipatory anxiety, agoraphobic fear/avoidance, panic-related sensation fear/avoidance, impairment in work functioning, impairment in social functioning. Conclusions : One session of group CBT appears to be an effective treatment of panic disorder by reducing the severity of all symptoms assessed on the PDSS. An attempt should be made to replicate the findings of this pilot study in a larger and controlled, comparative clinical trial.

Introduction: Return-to-work (RTW) can be a problematic occupational issue with detrimental impact on the quality of life of previously-employed breast cancer survivors. This study explored barriers and facilitators encountered during the RTW process in the area of cancer survivorship. Materials and Methods: Six focus groups were conducted using a semi-structured interview guide on 40 informants (employed multiethnic survivors). Survivors were stratified into three groups for successfully RTW, and another three groups of survivors who were unable to return to work. Each of the three groups was ethnically homogeneous. Thematic analysis using a constant comparative approach was aided by in vivo software. Results: Participants shared numerous barriers and facilitators which directly or interactively affect RTW. Key barriers were physical-psychological after-effects of treatment, fear of potential environment hazards, high physical job demand, intrusive negative thoughts and overprotective family. Key facilitators were social support, employer support, and regard for financial independence. Across ethnic groups, the main facilitators were financial-independence (for Chinese), and socialisation opportunity (for Malay). A key barrier was after-effects of treatment, expressed across all ethnic groups. Conclusions: Numerous barriers were identified in the non-RTW survivors. Health professionals and especially occupational therapists should be consulted to assist the increasing survivors by providing occupational rehabilitation to enhance RTW amongst employed survivors. Future research to identify prognostic factors can guide clinical efforts to restore cancer survivors to their desired level/type of occupational functioning for productivity and wellbeing.

We have created in our university material management environment, which uses database created by using LATEX-files, and LATEX2HTML translator and PHP language. In this paper we will define how these LATEX-files are transformed into our database. In this paper, we present work which we have done for providing the material used in the teaching of calculus to students at Lappeenranta University of Technology. This procedure can be divided into three separate steps: 1) creation of the LATEX-files, 2) implementation of these LATEX-files in 3) conversion of the base LATEX-files to the HTML-files. So far, we have stored hundreds of exercises with hints and solutions on our web server in addition to some theory that we felt is necessary for the students. In this paper we will also discuss the benefits and future of our functioning Web-environment [1].
