Abstract: This study applied multilevel modeling to examine how individual characteristics, such as gender and teaching experience, and contextual characteristics, such as principal leadership, school climate and collaborative culture influenced Korean secondary school teachers’ sense of job satisfaction. Previous research identified teachers with high job satisfaction to have positive influences on their students, making it important to understand teacher job satisfaction not only for teachers but also for students. Using data based on the secondary data and instrument from the 2013 TALIS teacher Questionnaire - [<ISCED level x> or PISA schools] (MS-TQ-(X)] to measure job satisfaction which is the dependent variable and the independent variables are school climate and collaborative culture are both measured by ordinal scare. Age is measures with Ration and lastly, gender is measured in normal scale. The descriptive statistics and inferential statistics are both used. The descriptive statistics makes use of chart and some simple graph to explain gender, age distribution and educational level. The influential statistics makes use of T-Test and multiple regression analysis inferential statistics with independent T-Test and Multiple regression analysis. It therefore concluded that Collaborative culture within an organization is very important, playing a large role in whether or not the organization is a happy and healthy place to work. Through communicating and promoting the organizational vision to subordinates, and in getting their acknowledgment of the vision, it is possible to influence their work behavior and attitudes. When there is good interaction between the leader and subordinates, there will be contributions to team communication and collaboration, and encouragement of subordinates to accomplish the mission and objectives assigned by the organization, which in turn enhances job satisfaction.

Abstract: Plant tissue analysis is the direct measurement of various types of nutrients present in plant at the time of sampling. It helps to diagnose the deficiency and toxicity of particular mineral element at particular growth stage of plants before the appearance of visual symptoms. This paper intended to review the various types of qualitative and quantitative techniques used to determine the concentration of mineral nutrients present in plant tissue. The quantitative concentration of mineral elements present in horticultural crops can be determined by atomic absorption spectrometry (AAS), inductively coupled plasma atomic emission spectrometry (ICP-AES), inductively coupled plasma mass spectrometry (ICP-MS), flame atomic absorption spectrometry (FAAS), graphite-furnace atomic absorption spectrometry (GF-AAS), spectrophotometry, ion-selective electrode method, X-ray fluorescence spectrometry, electromigration techniques, nuclear magnetic resonance technology and some electrochemical techniques. Review shows that atomic absorption spectrometry (AAS) is widely used destructive technique for the determination of several mineral elements such as nitrogen (N), phosphorous (P), potassium (K), calcium (Ca), sodium (Na), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), zinc (Zn) and boron (B). Other non destructive techniques such as DRIS and colorimetric method are also employed to determine the mineral nutrient concentration in plant tissue.

Abstract: Coronary artery disease (CAD) is the leading cause of illness and death worldwide. Prevention of the disease is undoubtedly the most important measure, and early diagnosis is another crucial aspect to make patients seek medical attention in a timely fashion so as to decrease the adverse outcomes from this deadly disease. Recently with the booming of artificial intelligence (AI) technologies, more researchers have been focusing on developing effective methodologies and tools in CAD early diagnosis and predictive models. Taking advantage of the complete records of total 4049 patients with 2678 patients having CAD and 1371 patients without CAD confirmed by the gold standard, cardiac catheterization, we utilized XGBoost to assess the risks of both CAD and myocardial infarction (MI) and achieved extremely high accuracies on CAD and MI prediction. Results shown by seven benchmarks were recorded, and they all demonstrated higher than expected scores. The assessment of the risks of both CAD and MI simultaneously by utilizing the identical set of data in a clinically orientated setting is a new approach. Outcome of this study shows that CAD diagnostics using machine learning can reach high accuracy. Large population of people may potentially benefit from the machine-learning models, by seeking early diagnosis and treatment, and consequently their morbidity and mortality from CAD and MI can be significantly decreased.

Abstract: The main energy source used in Cameroon is still biomass. For cooking and heating purposes, the majority of Cameroonians still rely on biomass, which is abundant and to certain extends renewable and affordable. Electricity and gas are still very lowly used, mostly because of non-availability and non-accessibility, especially in the rural areas. According to the Cameroon Energy Situation (SEC) in 2011, the energy consumption mix was 73% biomass, 20% oil and gas products and 7% electricity totaling around 6000ktoe (Kilo tons of oil equivalent) for the whole country and converted to about 0.3toe (tons of oil equivalent) per capita. A quick comparison with the world average per capita consumption of about 2toe shows that access to energy in Cameroon is still extremely low.This clear divide between the urban and rural areas is socially and ecologically alarming as a widening of this gap could be a very realistic future scenario.

Abstract: The present experiment was conducted at the Germplasm Centre (GPC) of the Fruit Tree Improvement Program (FTIP), Bangladesh Agricultural University, Mymensingh, during the period from April, 2012 to November, 2012to investigate the effect of germplasm and time of cleft grafting on the success, survivability and growth of grafts in Amra. The experiment consisted of two factors such as (i) three germplasm viz., DeshiAmra, BaromashiAmra and BorishaliAmra and (ii) ten different times of grafting viz., each 10 and 25 of April, May, June, July and August, 2012 following randomized complete block design (RCBD) with three replications under observation in poly tunnel condition. Results revealed that, the lowest time to bud breaking (3.15 days) and first leaf opening (8.94 days) with the highest number of leaves (32.12), graft height (26.21 cm),graftsuccess (86.59%) and survivability (83.48%) were required by the grafts of BaromashiAmra when grafted on 25 May. On the other hand, the highest time for bud breaking (10.89 days) and first leaf opening (14.27 days) with the lowest number of leaves (15.89), graft height (22.86 cm),graftsuccess (70.14%) and survivability (69.45%) were needed by the grafts of BorishaliAmra when grafted on 25 August. Therefore, the results of the present investigation suggest that 25 May grafting with BaromashiAmra performed the best; yet cleft grafting can be performed during April to August with above 70% success and survivability in different germplasm of Amra.

Abstract: An experimental study on the latent heat storage system (LHS) using paraffin wax as a phase change material (PCM) was performed to analyze thermal physiognomies. The use of phase change materials (BM) through latent heat storage (LSS) is an unusual approach to maintaining thermal energy. There is the benefit of high energy storage density and the equal temperature of the storage process. Tubes in shell type heat exchanger (HE) has been used in this project. Water circulates in tubes and around the tubes it has paraffin wax as phase change material. The focus is on charging and discharging of phase change material (paraffin wax), which is the melting and hardening of paraffin wax. The temperature distribution in paraffin wax is studied according to the different flow rates of the heat transfer fluid (HTF).The outcome revealed that the suitable inlet temperature (Th) for charging the system is 70° C. The results are obtained experimentally for different mass flow rates. This system can store thermal energy and can be used in heating applications as for heating water for winter.

Abstract: This article has been put forward to give insights into Ghana’s healthcare policies which are regarded as the best on the retrogressive billboard of health policies in the sub- Saharan Africa. Healthcare policies in Ghana have been Universalist in approach providing free universal healthcare after independence in 1957 until the early 1980s.The structural adjustment program through the collaboration of the Bretton wood institutions was introduced in the sub-Saharan region to rescue the economy because of increased strife, corruption, myriad sociopolitical obstacles which led to the widespread of poverty, malnutrition, diseases and many more. These economic measures included cost recovery and cut back spending in the health sector. Nevertheless, there has been effective intercession to battle the problems encountered in the 1980’s.Despite the effective interventions, there have been challenges encountered during policy implementation in Ghana. For the first time in academic literature, this article propounds six key developmental stages in Ghana Health Sector and further posits the prospect and challenges in Ghana’s healthcare policies and recommendations are thoroughly discussed in this paper.

Abstract: Administration and management in primary schools in Malawi is very crucial because it determines the outcome of many undertakings in the school. It is central to effectiveness in the school as an institution in the same way that its negative manifestation would equally crumble it. This paper investigates the various challenges that management and administration faces in primary schools in Malawi. It is based on challenges solicited from records kept by head-teachers of selected primary schools in different zones in the districts of Mangochi, Balaka and Blantyre as well as data from one Primary Education Advisor’s office for Ulongwe Zone in Balaka. The challenges range from financing of administrative duties through lack of collaboration with relevant stakeholders to lack of pre-service and in-service training for both head-teachers and other members of staff among others.
