Life Skills Education

Taman Sari Sub-District, Bogor Regency has the potential for fertile soil. But these lands have not been tilled properly. Narrow housing conditions, especially for poor people, do not allow residents to plant crops. Causing the lack of consumption of vegetables; which causes residents become easily sick. In addition, there is also a lot of plastic waste, especially bottled drinking water and other things that come from tourists and fishermen who have not been processed. This condition gave rise to the idea to provide life skills training in making vertical gardens, hydroponic plants and waste management. Besides the need for makeup and haircutting skills also needed especially for orphans fostered by Yasayan Usawatun Hasanah. Community Service Activities (PkM) aims to foster community awareness of the cleanliness of the environment and empower citizens to be more creative and entrepreneurial. Therefore, in addition to the types of activities requested by the residents, UPBJJ-UT Bogor will also teach about identifying the economic value of the work done in the form of determining the cost of goods sold / production. This activity was attended by 50 orphans and it ran smoothly and successfully. Now orphans already have life skills that hope can lift their economy.

Productivity Assessment

Measuring the productivity of employees has been one of the concerns of IT organisations globally. It is indispensable to calculate the cost of the project vis-a-vis the time estimate. While calculating the lines of coding (Loc) has generally been the common criteria for programmers, it is not always considered an effective measure of the actual work done. The time spent on activities like attending training programmes, participating in meetings, co-coordinating with colleagues, or conceptualising, is presumably unaccounted. Questions lurking unanswered relate to the effective criteria and international benchmarks. Amusingly most companies have their own home-grown productivity calculators to track the progress of their projects. Productivity measurement is equally important for an organisation as well as an IT worker. Awareness of productivity paves way-for mutual progress-self and the organization. This paper, through illustrative-case examples, provides a holistic perspective of personnel productivity assessment methods used in Indian IT industry.

Steam turbine owners are often searching for opportunities to increase power output. Increases in steam turbine flow capacity yield a proportional increase in power output, but there is more to increasing capacity than just opening up nozzle areas. This paper describes how Mechanical Dynamics and Analysis personnel increased the flow capacity and power output using original blading on a large, supercritical, reheat unit while maintaining a high level of efficiency. Much attention was given to the as-left stage properties in order to minimize the change in efficiency from the design levels. The work is documented using a timeline which centers on the outage. Much of the engineering work done prior to the outage minimized the time necessary during the outage to complete the modifications. Before and after test results demonstrate the cost-benefit of the capacity increase.

Abstract An account is given of work done by the Navy Bureau of Ships with cathodic protection of active and reserve ships. Because it is difficult to dissociate costs for maintenance and corrosion protection it is impossible to say whether or not the cost of cathodic protection of active ships is merited. Because corrosion damage to hulls seldom is considered except when perforations occur, or in destroyers and sub-marines where plates are thinner and original dimensions more critical, there is some belief that cathodic protection for all ships cannot be justified on a cost basis. With inactive ships, however, the reverse is true. Indefinite extension of drydocking times, the interval contingent on the exhaustion of anti-fouling paints, is anticipated. Initial cost of cathodic protection of active destroyers, submarines, and five types of reserve ships is tabulated. Details of cathodic protection systems for reserve ships are given. Criteria of protection differ somewhat from the accepted standards. In polluted waters inactive ships may require a potential in excess of 1 volt, while in other high resistivity waters 0.85 to 0.95 volts are sufficient. Some data are given on the cathodic protection of active ships. Merits of sacrificial anodes versus impressed current are listed. Extensive further activity in cathodically protecting active ships is contingent on the outcome of trials now under way.

This laboratory exercise demonstrates fundamental principles of mammalian locomotion. It provides opportunities to interrogate aspects of locomotion from biomechanics to energetics to body size scaling. It has the added benefit of having results with robust signal to noise so that students will have success even if not “meticulous” in attention to detail. First, using respirometry, students measure the energetic cost of hopping at a “preferred” hop frequency. This is followed by hopping at an imposed frequency half of the preferred. By measuring the O2 uptake and work done with each hop, students calculate mechanical efficiency. Lessons learned from this laboratory include 1) that the metabolic cost per hop at half of the preferred frequency is nearly double the cost at the preferred frequency; 2) that when a person is forced to hop at half of their preferred frequency, the mechanical efficiency is nearly that predicted for muscle but is much higher at the preferred frequency; 3) that the preferred hop frequency is strongly body size dependent; and 4) that the hop frequency of a human is nearly identical to the galloping frequency predicted for a quadruped of our size. Together, these exercises demonstrate that humans store and recover elastic recoil potential energy when hopping but that energetic savings are highly frequency dependent. This stride frequency is dependent on body size such that frequency is likely chosen to maximize this function. Finally, by requiring students to make quantitative solutions using appropriate units and dimensions of the physical variables, these exercises sharpen analytic and quantitative skills.

INTRODUCTION ‘Payment by results’ was introduced with the aim of providing each trust with a transparent and fair remuneration for the work done. Hospitals are paid a tariff for each Healthcare Resource Group (HRG). The tariff is calculated at a national level, by means of a complex manipulation of historic financial data. However, the financial viability of a hospital relies on these payments and so accuracy is vital. PATIENTS AND METHODS We conducted a cost analysis of shoulder arthroscopic procedures carried out at an elective orthopaedic unit. This unit is self contained and well audited, providing an unique opportunity to make a more accurate cost analysis. We calculated the cost of the facility, consumables/implants, anaesthetics and staff pay. This was then compared with the amount paid to the trust. RESULTS All arthroscopic operations performed at our institution attract a tariff of £1780. Our cost of a subacromial decompression was £1307, a profit of £473. A rotator cuff repair was £2672, a loss of £892. CONCLUSIONS The tariff is inaccurate. The arthroscopic HRG is too general and fails to address the extra time and expense of equipment some procedures utilise. We found cost was very sensitive to length of operation. Delays and even teaching can make a ‘profitable operation’ lose money for the trust.

Education is the biggest asset of a nation with the aim of contributing in the form of skills to children not to awkward facing the future. While the funcion of education is to form characteristic and the child morality of nation in order to have integrity with high morals and love the nation. So that, the education is the most veluable treasure belonging to nation. To improve the quality of education is not easy as flipping a hand. There are a few things that need to be made a foothold. One of them is education incurred the competen as well as meet the learning facilities. That is one of the things that needs to be taken by the managers of education.To complete it needs the cost of expensive, so it is usually a problem for managers of eduacion. Because, if they rely solely on education budget from the government and the students, then it will be difficult to improve the quality of education. While the things that should be financed by the institution’s of education is not only the supplies of education, but also pay the employees and maintenance of the school. Moreover, the institution of education that a public school  to meet the needs is not easy. So, to improve the quaity of education as well as spend the treasures of institution including the treasure of edutator.There are several stages that should be applied in developing enterpreurship in the world of education, so that it walk well, those are; identify the aim that will be achieved, ready to accept the risks that will be accepteble to both the power of money as well as time, prepare the ability to make the plan of organizing, coordinating and implementing programs, committed to work hard all the time and believe to be successful on all work done, develop good relationship with costumer, educational personnel, parent, community, social institutions, the government and the corporate world that impact educational activities, receiving the  benefit and responsibility for the successes dan failures.

Construction activities in Nigeria are dominated by foreigners’ managed construction enterprises. These companies constitute less than 5 percent of the number of construction enterprises in Nigeria; however, they are involved in over 95 percent of high net-worth construction activities. Nigeria Indigenous Construction Enterprises (NICE) are faced with numerous challenges that have limited their performances. This makes construction clients to patronize foreigners’ managed construction firms because of the flaws in the performances of NICE. There have been measures on how to make NICE relevant, but most attempts have achieved little or no success. This study was aimed at examining the challenges of NICE in the face of the present scenario and to proffer ways of possible improvement. Primary data were collected by administering a structured questionnaire to both clients and contractors who are involved in the day-to-day construction activities. Data collected were analyzed using descriptive statistics, mean score and Kruskal-Wallis test. The study identified 25 challenges of NICE and 18 ways of improving NICE performance through careful literature reviews. The analysis of the total ranking among stakeholders revealed that limited technical expertise, insufficient profit on projects and delay in the payment of contractors for work done were the highest-ranked challenges. Application of project management techniques in construction activities, quality control of materials and improving production capabilities were the most important means of improving NICE performance as identified. The findings of this study will help to improve the competitiveness of indigenous contractors if well implemented as it will help to reduce the cost of construction as the competition nest for performing contractors will be widened.

Poor Class

The current paper talks about the unavoidable class system that we all are entrapped in. The basic issue lies in the fact that the society we live in and grow operates on the system of class consciousness. The rich/bourgeoisie class uses and abuses the low or poor class to get their work done, whereas the poor or the proletariat has no choice except to be manipulated by the rich class for the cost of labor, for they know that their survival lies in the manipulation. It has become an accepted phenomenon that the rich class/bourgeoisie exploits the poor class for their needs and desires. The rich class has become totally dependent on the proletariat and they know they cannot move without them. As the society is designed and planned on unequal footings so, on the one hand, the rich class has found a medium to exploit the labor class but at the same time the proletariat are not allowed to interact with them and furthermore there is a bleak chance of their unification as the lower/labor class itself is a stigma in the eyes of the bourgeoisie.
