Street-level bureaucrats (SLBs) have a great opportunity in taking discretion in public services. This is because in the provision of services is often confronted with the scarcity of resources that are owned, so that requires them to make policies (discretion) to get around the scarcity of these resources. Discretionary authority possessed by SLBs can be a "disaster" if not used professionally and carefully, especially if it is done in the field of health services that can have a negative impact on the community served. This study aims to reveal various forms of discretion taken by SLBs in health services in Public Health Center (PHC) in Makassar City, what is the background of taking discretionary actions, as well as the impact of the discretion taken. This study uses a qualitative approach with in-depth interview data collection techniques. The number of informants interviewed was 24 people consisting of the head of the PHC, doctors, nurses, midwives, pharmacists, as well as window clerks. Data processing and analysis using the NVivo 12 Plus application. The results showed that the level of discretionary use was different for each SLBs. Courage to take discretion is strongly influenced by the experience and independence of SLBs, as well as considering the impact on patients. In general, the discretion taken solely aims to facilitate service and is based on the desire to save the lives of patients served

This paper reviews the processes of blast wave propagation in joint junctions of capital and preparatory mine workings, the blast wave is formed in blast of air-coal mixture in the seams of horizontal and inclined occurrence. Methods of mine aerogasdynamics applicable to various geometrical combinations of joints, were used for simulation and calculations. At the initial stag of doing the research work, simplified variants of rectangular types of joints were selected for studying aerogasdynamic and thermophysical processes emerging in blast of aerosols of coal dust. The source data for building a model in ANSYS FLUENT software were adopted based on the experimental studies conducted by the authors on identifying the damaging factors of blast in the laboratory device for conducting blasts of air-coal mixture in confined space. The maximal pressure of the blast and the speed of pressure build-up in blast was identified in a 20-litre spherical blast chamber. It was identified that the maximal blast pressure emerges in the laboratory device in forced blast in the volume of coal dust of 63-94 micrometers. As a result of constructing the model, according to the obtained experimental data, the probability of emergence of reflected waves is established. Emergence of reflected waves, according to the model built by means of ANSYS FLUENT, causes formation of local zones of increased pressure. It was established that the highest pressure develops in the front of blast waves in their mutualencounter incident wave+ reflected wave and reflected +reflected blast waves. In this respect, the biggest hazard in blast pressure build-up in the blast wave front is formed in mine workings of rectangular T-shaped intersection. As a result of calculation and modelling, the fact of the consistency of the obtained experimental results with the actual process of blast wave propagation in elastic media, was identified. In addition, the obtained experimental results in computer simulation, with use of ANSYS FLUENT software, mine aerogasdynamic processes of blast wave propagation, enable to calculate promptly and efficiently fairly complex joint junctures of mine workings. Work in this area will be continued.

Conventional methods such as cropping or resampling can introduce more losses in information or distortion in resolution. In this paper we propose an improved seam carving algorithm which incorporates multi scale retinex techniques. We propose a MSR improvement for image enhancement. MSR is used on images under non uniform illumination in terms of either color or lightness and has satisfactory results to achieve color constancy and dynamic range compression. MSR is extremely sensitive to noise speckles that cameras produce in low light areas, and it has unsatisfactory effect on areas with normal or intensive illumination. Moreover, MSR uses a gain-offset method for prior-to-display treatment and can lead to apparent data loss on images. This study replaces the logarithm function in MSR with a customized sigmoid function to minimize data loss, and adapts MSR to images by merging results from sigmoid-MSR with seam carving on original images. Experiments show our framework, when applied to images, can preserve areas with normal or intensive lighting and suppress noise speckles in extreme low light areas, we have demonstrated superior performance upon the current seam carving –multi scale retinex methods

The addition of pozzolan material, such as silica fume in order to improve mortar or concrete quality has been reported in many papers. However, the previous experimental design was only limited to factors that had a significant influence on the response. In addition, the results of the research analysis are only able to determine differences between the levels of factors and show the maximum or minimum response values, limited to the level of factors planned only. Response Surface Method used in the experiment of this study can analyze the problems of several independent variables that affect the response variable. The basic idea of this method is to use experimental design involving statistics to find the optimal value of the effect of adding silica fume as a partial substitute material for mortar to the compressive strength resulted. The design of the experimental proportion in this study was carried out by replacing 20% silica fume in cement as the middle boundary. Furthermore, the proportion of silica fume, cement and sand is reduced in number to the lower limit and added to the upper limit of the experimental design. Conclusions achieved; 1) Analysis using the Response Surface Method shows the optimal composition of mortar mixture obtained by adding 23.6% silica fume to cement, so that the optimal compressive strength test is at 55.8 MPa. 2) The optimal composition can also reduce the absorption of mortar to water, which only absorbs 5.34% water compared to mortar without silica fume which absorbs water up to 8.84%. 3) Addition of silica fume to mortar can increase 1.33% pH of mortar. The pH of the mortar with the addition of silica fume remained in alkaline conditions 9.75

In addition, the results specified that Change in the road side slope has a significant impact on storm drainage efficiency than road longitudinal slope.

The challenge which is faced in the slums development is not only in the executive works but in interaction between the various development elements to create a community (population) that is distinguished in a suitable level of living. The objectives of development come through planning, implementation, and management. If these preliminaries dont achieve the standard living results, then the development is unable to attain its aims, therefore; the spending on this development are wasted the resources. One of the most popular expressions of urban poverty in developing countries is the increase of slums and informal settlements. These settlements have the most deplorable living and environmental conditions within the city. They are characterized by inadequate water supply, squalid conditions of environmental sanitation, overcrowded and dilapidated habitation, hazardous location, insecure tenure and vulnerability to serious health risks among many others. So the objectives of this research are the ensuring of a durable improvement of housing conditions and housing environment of poor people living through standard of living indicators. The standard of living includes six domains, education, health, infrastructure, and house, housing environmental and household economic status. Therefore, each domain contains a group (pack) of indicators. The total number is (37) indicators. The research aims to analyze and understand the level of Living Index, also to notice and observe the range of the improvement in slums towards achieving theres goals and reach the suitable level of living. It focuses on the indicators and their roles in development. The research also emphasizes on the effective role in evaluation of building (construction), developing; i.e. the community converts from consumer beneficiary community to a producer and effective community that makes decision in all stages of developing. Such as: economy, building (construction), society, and environment
