Recently, many local airports in Japan are considering to extend their runways, so accommodating passenger traffic. But most airports are obliged to extend their runways into the sea on account of the shortage of land and complaints from their neighbors about jet-plane noise. Tokushima Airport is one of such local airports, which is situated on the coast along the Kie-Suido Channel as shown Figure 1. The length of the runway of Tokushima Airport is 1500 m at percent, so a plan to extend the runway by 600 m into the sea has been proposed by the local government. However, Matsushige beach, where the airport is located, is now so seriously eroded that offshore breakwaters are being constructed in the south and the northern part is used for sea-bathing. Therefore, it is necessary to estimate the change of beach profiles, especially of the shoreline, caused by the extension of the runway, and to find countermeasures against unfavorable change. A movable bed model was constructed to estimate such changes, because no numerical simulation using a computer has been developed to estimate changes of a complicated beach topography. Of course, the universal dynamic similarity does not hold for model studies on sand transport problems. Therefore, the characteristics of sand transport at the site are first clarified through analysis of the field observation data, and then the model scale, bed material, and test waves are determined in such a manner that the topographic variation in the model sea bed will become similar to that in the prototype. But, in general, it is difficult to make all of the variations of the sea bed in the model similar to that in the prototype. In this model experiment, the long term changes of the shoreline has been taken as the most important phenomena to be reproduced in the model.

In deep water, pipelines are generally laid directly on the sea bed and a pipeline’s as-laid embedment is a major source of uncertainty influencing the assessment of pipe-soil resistances, pipeline lateral buckling formation as well as lateral buckling response, end expansion and walking behavior. In order to have good control of the uncertainties in pipeline as-laid embedment, pipe laying effects, including static and dynamic pipe-soil vertical contact loads and the likely degree of soil softening due to pipeline oscillation at touch down zone should be reliably predicted. In this paper a new procedure is introduced that uses OrcaFlex [1] to determine pipe laying effects and a cycle-by-cycle approach to predict pipeline as-laid embedment. Validation of the procedure is also presented in this paper by comparing pipeline as-laid embedment results calculated from the procedure with upper and lower bound values developed from field observation data. Very good agreement is obtained. In the study, it is found that pipe-soil vertical contact load amplitude, pipe horizontal oscillation, and duration of the oscillation at touchdown zone are important to soil softening as well as pipeline as-laid embedment. In addition, results calculated from the procedure were also compared with those evaluated from the SAFEBUCK guideline [2]. It was found that results from the SAFEBUCK guideline, in general, underestimates the pipeline as-laid embedment.

Introduction: The doctor-patient relationship is based on good quality of communication and interaction with thepatient, so that it not only can help speed up the healing process, but also make the patient feel comfortable sincethe first visit to the health service. When dealing with pediatric patients, the ability to build a relationship of mutualtrust is done with a more open, honest attitude and understanding what they are feeling. Aim of study: This studyaims to see a real picture of the relationships, interactions and interpersonal communication between doctors andpatients in health care. Method: This study uses a qualitative descriptive study where data is obtained throughinterview transcripts, field observation data notes and photo documentation. A total of 7 participants were obtainedthrough a purposive sampling technique on pediatricians who are accustomed to engaging in effective relationships,interactions and communication with pediatric patients, families and introductors. Data were then analyzed usingthe Miles and Huberman method. Results and Discussions: The results of this study indicate 66.67% of parents orfamily members have smoking habits around children and 66.67% smoke when gathering with family. Most parentsor family members have the habit of opening windows as much as 75.76% of people. The results of bivariateanalysis showed that there was no relationship between nutritional status and the incidence of unde r-fivepneumonia (p = 0.732) and there was a relationship between smoking behavior and under-five pneumonia events (p= 0.021). Besides, smoking behavior at home can increase the incidence of pneumonia in toddlers. Conclusions:Therefore it is necessary to increase family awareness so as not to smoke near children.

The article aims to analyze the interface of reflexivity, knowledge and ecologic awareness in the context of hospital work, based on data collected in a qualitative case study carried out at a public hospital. Field observation data and interviews are discussed in the light of sociologic and philosophic references. Workers expressed the interface between knowledge and action, in which there is a cycle of lack of knowledge, automatism in the actions and lack of environmental awareness, posing limits to individual awareness and to responsibility towards environmental preservation. Increased debate and education, including the environmental issue, are needed in the context of hospital work. Although hospital work is reflexively affected by the environmental problem, that does not guarantee the reorientation of practices and responsible action towards the environment.

The reliability of the computer numerical control (CNC) system affects its processing performance and is a major concern in the manufacturing industry today. However, existing reliability models to assess the reliability of the CNC system often exhibit relatively large errors due to inadequate treatment of small samples. In order to get around the constraint of limited lifetime failure data and take full advantage of existing reliability parameters in traditional reliability models, a multisource information fusion-based reliability model grounded on Bayesian inference is proposed to deal with the small sample size. The prior distributions are derived by using the probability encoding method and conjugate distribution based on the idea of multisource information fusion. Then, using the Jensen–Shannon divergence (JSD) to measure the similarity between prior information and field observation data, a constrained optimization problem is established to determine the respective weight of prior information and field observation data. Finally, by conducting the reliability analysis of repairable CNC systems, the validity of the proposed model and its prior distribution derivation method are verified.

<p>Designing a methodology for mapping and studying soils in a quick and inexpensive way is critical especially in developing countries like Zambia, which lack detailed soil surveys. Therefore, this study was conducted to determine the potential of Landsat 7 ETM+ data (Enhanced Thematic Mapper plus) in mapping soils in Chongwe, a semi-arid region in Zambia. In addition, the study attempted to establish how accurate spectral soil maps produced by digital analysis of Landsat data can be and how such maps compared with field observation data. Also, in situations where there was poor agreement between Landsat data and field observation data, possible causes of such discrepancies where determined.</p><p>A soil inventory of the Chongwe region of Zambia was prepared using computer-aided digital analysis of two Landsat 7 ETM+ satellite images acquired in the dry and rainy seasons to investigate the hypothesis that there is a relationship between Landsat spectral reflectance and certain soil types and that this relationship can be used to map soils with reasonable accuracy.</p><p>The study revealed that digital analysis of Landsat 7 ETM images has the capacity to map and delineate soil patterns with reasonable accuracy, especially when acquired during the dry season when there are long periods of cloud free skies, low soil moisture and minimal vegetation cover. The overall agreement between the Landsat classification and reference data was 72%, indicating a definite relationship between Landsat imagery and soil types.</p><p>In terms of soilscape boundary delineation, the Landsat derived map was had a higher level of agreement with field observations than the conventional soil map. In addition, the study showed that overall, upland areas have a better agreement with Landsat spectral data compared to lowland areas, probably due to the diverse origin of sediments and low spatial extent of most landforms in lowland areas.</p>

&lt;p&gt;Lake eutrophication is a key point in water environmental problems in the world. Spatiotemporal variations of nutrients and chlorophyll-a and eutrophication index in Poyang Lake, the largest freshwater lake in China, are analyzed in this paper basing on field observation data at 17 sampling points from 2011 to 2016. The results show that nutrient concentrations have obvious seasonality characteristics and present bigger values in the low water period than the high water period. The peak value of chlorophyll-a concentration appears in July and October respectively. As a whole, the eutrophication index in the low water period is higher than the high water period, and the maximum value is found in October which mainly due to the high chlorophyll-a concentration. Poyang Lake is at light eutrophication level from 2011 to 2012, and mesotrophic from 2013 to 2016. From the perspective of space, nutrient concentrations in the southern part of the lake is higher than the northern part in general, and chlorophyll-a and eutrophication index show the similar law. This paper makes a quantitative analysis for spatial and temporal variations of eutrophication which benefit the water management especially water pollution control in Poyang Lake&lt;/p&gt;

Movable Bed

Hydraulic model studies were conducted to aid in ascertaining the technical feasibility and optimum design factors of the perched beach concept. Among these were two-dimensional, movable-bed studies to determine an estimate of the amount of sand which would be lost seaward over the submerged toe structure by normal and storm wave action, the optimum elevation of the submerged toe structure, and the length of a stone blanket required to reduce seaward migration of sand to a minimum. The model beach was subjected to test waves until equilibrium was reached for a wide range of wave conditions for both the existing beach and the perched beach. Test results indicate that (a) little or no beachfill material will be lost seaward of the toe structure for normal wave conditions but the larger storm waves may cause erosion of the perched beach, (b) the installation of a stone blanket shoreward of the toe structure will reduce the amount of beach erosion, (c) if the beach fill is extended a sufficient distance seaward, the toe structure serves no useful purpose, and (d) a three-dimensional movable-bed model study is feasible and is necessary to determine the final design features of a perched beach.
