Health is an investment to support economic development and has an important role in efforts to reduce poverty and improve the quality of human resources. One of the diseases that often become serious problem in health sector that is Dengue Hemorrhagic Fever (DHF). In Indonesia, many mosquitoes cause dangerous DHF such as Aedes aegypti, Aedes albopictus, Aedes africanus, anopheles and others. In this study, we analyzed and applied SIR (Susceptible, Infection, Recovered) mathematical models and their interpolation to determine whether a contagious disease (DHF) can become endemic or not. Therefore, in this study aimed to determine the a special form of model of SIR to analyze the spread of DHF in Maluku Province and the stability analysis of this model and also interpolating the data of DHF transmission in Maluku Province. Furthermore, it can be obtained the characteristics of equilibrium point of each sub population. Based on the research conducted it can be concluded that from the entire population of Maluku Province is 1.686.469 vulnerable people infected with DHF and endemic disease with the basic reproduction value is 3,44.

R&D outsourcing becomes the often-adopted strategy for firms to innovate. However, R&D cooperation often ends up with failure because of its inherent quality of instability. One of the main reasons for cooperation failure is the opportunistic behavior. As the R&D contract between firms is inherently incomplete, opportunistic behavior always cannot be avoided in the collaborative process. R&D cooperation has been divided into horizontal and vertical types. This paper utilizes game theory to study opportunistic behavior in the vertical R&D cooperation and analyzes the equilibrium of the cooperation. Based on the equilibrium and numerical results, it is found that the vertical R&D cooperation is inherently unstable, and the downstream firm is more likely to break the agreement. The level of knowledge spillovers and the cost of R&D efforts have different effects on firms’ payoffs. When the level of knowledge spillover is low or the cost of R&D efforts is high, mechanisms such as punishment for opportunism may be more effective to guarantee the stability of cooperation.

Self-excited vibrations significantly reduce the milling productivity, deteriorate the quality of machined surface and tool life. One of the ways to avoid these vibrations is to modify the cutting parameters based on the stability analysis results. A method of numerical simulation of self-excited vibrations in the time domain can be used for this purpose. A comparison of numerical simulation results with those from experiments conducted using a milling machine is presented. The results confirm the correctness of applied modeling.

Abstract The collapse of the embankment is a problem that needs attention to find the right solution, so that the risk can be minimized. The condition of the embankment is influenced by the strength of the soil layer of the embankment, groundwater flow in the embankment, the condition of the water level of the embankment and human activities around the embankment. Changes in the quality of soil density in the embankment can form cavity zones within the embankment which cause changes in groundwater flow patterns in the embankment. The degradation of the soil layer of the embankment can cause piping, overtopping which is the cause of erosion of the embankment body and disturbs the stability of the embankment. Therefore, to determine the condition of the embankment soil layer, research on the stability of the embankment has been carried out using the geoelectric method at the location of the embankment in the Cipancuh and Penjalin reservoirs, so that an image of the embankment soil layer is obtained to determine the cavity zones in the embankment, the flow pattern in the embankment soil layer. Keywords:  cavity zones, flow patterns, geoelectric methods, the stability of the embankment.

One of the manifestations of underdevelopment is malnutrition and unhygienic living conditions. These contribute to lowering productivity levels of labour thereby affecting both industrial and agricultural output. This gives rise to other problems such as unemployment, and underemployment which leads to falls in family income and a consequent decline in living standards. The cycle is then repeated. However, till the early 1970s most LDCs did not give due weightage to the improvement of health conditions as they felt that resources would be better utilised in the directly productive sectors of the economy, for example, agriculture and industry to name two. However, the last twenty years has seen, through the basic needs approach, the role that health can play in promoting development. Expenditures in the health sector came to be seen as investments in human capital. The benefits of such investment became apparent from the improvement in the quality of human resources which was reflected by increases. in productivity of the labour force as well as by increasing the length of the expected working life of labour. Thus the provision of better health facilities has a two-fold effect: first it increases the productivity of the existing labour force and, second it increases the quantity of human resources available in the future by increasing the length of working life. Keeping this in view, the Government of Pakistan's policy with regard to the provision of health can be summarised in a five-point agenda:

For many years now, the Malaysian government's population policy has included both a growth component and a distribution component. The growth component, adopted in the Second Malaysia Plan (1971–75) and still in force, was the goal of reducing the rate of population growth from 3 per cent to 2 per cent by 1985. The distribution component, first enunciated in a coherent way in the Mid-Term Review of the Second Malaysia Plan, is a strategy for regional development with direct population redistribution consequences. The Third Malaysia Plan (1976–80) elaborated the population situation and goals in greater detail but their broad thrust remained essentially unchanged. The Fourth Plan (1981–85), while maintaining the target of lowered growth rates, emphasized the quality of human resources and was sanguine about the prospects for economic development far outstripping the rate of population growth. Indeed, earlier concern with unemployment had been replaced by worries about the emergence of labour shortages.

Lam Dong is evaluated as a potential province in socio-economic development in the Central Highlands for many years. The development speed of Lam Dong contributes significantly to the development speed of the Central Highlands and the whole country. Contributing to that growth, we must mention Lam Dong's strategy of investing in the quality of human resources. More specifically, the input of high quality human resources based on local strengths is the fast, strong and sustainable direction of Lam Dong in recent years. This paper focuses on analyzing and evaluating the quality of human resources in Lam Dong in three aspects considered to be "three specialties" of Lam Dong which are human resources in the field of high-tech agriculture and human resources. in the field of tourism services and human resources for ethnic minorities. Since then, the article proposes solutions directions in the strategy for developing human resources, especially high-quality human resources of Lam Dong in the future.

Abstract. The stabillity of baselines produced by Cheongyang (CYG) observatory from a period of 2014 to 2016 is analysed. Step height of higher than 5 nT were found in H and Z components in 2014 and 2015 due to magnetic noise in the absolute measurement hut. In addition, a periodic modulation behaviour observed in the H and Z baseline curves was related to temperature variation of about 20 °C in the fluxgate magnetometer hut. The quality of the baselines was improved by correcting the discontinuity in the H and Z baselines. Moreover, the stability of the both baselines was also improved by about 6 nT/year from 10 nT/year by performing the temperature effect correction.

ABSTRACT The functions of university libraries (UL) are to provide the bibliographic, documentary and informational infrastructure to support scientific activities, as well as to disseminate the knowledge produced by their academic entity to society. To achieve their mission, ULs need to be evaluated and, in Brazil, this evaluation is done by the National Student Performance Exam (ENADE - ExameNacional de Desempenho de Estudantes) through the Student Questionnaire (SQ). The present study evaluated the quality of the indicators used in the SQ for the evaluation of ULs. This quality was evaluated by considering the presence of the following essential properties for good indicators: stability, validity and importance of parameters. For the stability analysis, the SQ questions were repeated in the period from 2004 to 2014. Regarding the validity, a correlation analysis was performed between the results obtained in the SQ with another theoretically related indicator. For the analysis of the importance, a group of specialists was formed, composed of librarians with experience in the management of ULs and, through the Delphi method, indicators were evaluated as to their relevance. This work verified that the indicators used by ENADE are considered important, but they do not have stability and validity.

In the modern era, population problems considered as one of the important thing which should be solved seriously by government agencies through ‘human-welfare’ based policy regarding population for contributing to minimize the population problem and di-rectly for successing development. That is why in the  context of developmental policy, residents must be considered as subject, not as object of development. The population based policy must immediately formulated as guidelines for directing development implemen-tation comprehensively and synergy in producing human resources which able for global competition. Synergycity population based policy with quality of human resources, requiring quality education as a systematic method for improving Indonesian people by several quality such as life skills, personal skills including self awareness and thinking skills, and social skills, academic skills, and vocational skills.
