Recently, the amount of the construction and demolition wastes has rapidly increased due to increasing construction projects. In the past, most of the construction and demolition wastes were buried in the ground of thrown away. Illegally, without any treatment, so various harmful environmental pollution problems were occurred. In this study, the domestic data on the amount of the construction and demolition wastes and the disposal methods were collection and analysed. Specially, the recycling and management systems of the construction and asphalt concrete wastes were studied. A new technology and necessary policy for recycling were suggested. In general, the industrial wastes were produced in the particular place, and the amount and the characteristics of the wastes able to be estimated by the studies on the treatment technology. And the investment of the facilities for the industrial wastes have been made continuously. But little attention has been relatively given to the treatment technology. And system for the construction and demolition wastes for the political support and facilitation on the proper treatment and the recycling, the necessary of information exchange system and the manifest system for treatment of waste on commission were recommended, and also devised methods to develope and support the recycling industry. In the future, the subject of study is going to carry out analysis of economic and market in making products.

Recently, several investigations revealed that after unilateral brain damage, movement abnormalities were exposed on the ipsilateral side as well as the upper extremity contralateral to the damaged hemisphere. Even the motor abilities had significantly recovered from ipsilateral motor deficits on not only simple sensoriomotor function, also clinical assessments since subacute stage, although could not completely returned. Such motor deficits were detected in a diversity of motor tasks depending on the interhemispheric specialization, further in clinical evaluation and a daily of activities. In the clinical features, muscular weakness, sensory loss and impaired manual dexterity were observed. In a laboratory experiment, there were increasing evidences that the kinematic processing deficits was founded in various-specific motor tasks, which ranged from simple basic element to complex tasks, such as tapping task, step-tracking, goal directional aiming task, and iso(and non-)directional interlimb coordination. In the point of view, the manifest understanding in related to ipsilateral deficits provide the clinicians with an important information for scientific management about brain injured patient's prognosis and therapeutic guidelines.

The purpose of this study was to provide the basic information of making Skate pipyun made of skate skin. Test for quality characteristics of skate pipyuns seasoned with garlic, ginger, rosemary and basil were carried out. Hardness of GAR(4% of garlic and rosemary) was the highest, while that of GIB(4% of ginger and basil) was the lowest. As for the adhesiveness, springiness and cohesiveness, each specimen did not manifest significant difference. Water contents (82.43~85.56%) were no significant differences. The pipyuns added with spices and herbs were appeared weakly alkali with a range of pH 8.46~8.58. In the sensory evaluation, GIB was the most preferred in overall preference with significantly higher evaluation of flavor, savory taste, and lower fishy odor. The stability of gels decreased during storage at $10^{\circ}C$ for 8 hours, and at $20^{\circ}C$ for 60 min, and the greater was in GIB. Therefore, heating a mixture of 40% skate skin with 60% water for 10 min is recommended as optimum conditions for producing Skate pipyun.

Purpose: Even though the breast is not removed, women with a breast conservative operation(BCO) are suffering from the psychosocial distress comparable with mastectomies. The purpose of this study was to identify how clinical nurses view essential nursing problems and nursing approaches to post operative breast cancer experiences. Method: To identify the clinical nurses's interpretation, they were asked to respond to a case involving a woman struggling with breast cancer. The nurses' responses were analyzed using a manifest content analysis strategy to determine themes in problem identification and nursing care strategies. Result: The clinical nurses recognized that most of the patient's experiences originated from a psycho-social problem. Fifteen nurses(83%) interpreted the breast cancer woman's experience derived from her psychosocial problem. They identified the most effective nursing approaches for breast cancer women following surgery as counseling and providing information. Conclusion: In conclusion, the results revealed that a psychosocial skill including an empathic communication skill is essential for excellent nursing in post operative patient care.

Voltage instability has been studied for some decade now. But, There is not generally accepted definition of voltage instability because of the complex phenomenon and the variety of ways in which it can manifest itself. Both IEEE and CIGRE have the respective definitions. The areas of voltage instability research are the analysis, simulation and countermeasure of voltage instability. It needs to model the components of the power system to simulate the voltage instability and voltage collapse. At the beginning, the static simulation was used. This method provides the voltage stability indices and it requires less CPU resource and gives much insight into the voltage and power problem. However, it is less accurate than the dynamic simulation peformed in the time domain simulation. So, when it appears difficult to secure the voltage stability margin in a static stability, it is necessary to perform the dynamic simulation. To perform time-domain simulation, we have to model the dynamic component of the power system like a generator and a load. The dynamic simulation provides the accurate result of the voltage instability. But, it is not able to provide the sensitivity information or the degree of stability and it is time consuming and it needs much CPU resource. In this Paper, we perform a dynamic simulation of voltage instability and voltage collapse using EMTP MODELS. The exponential load model is designed with MODEIS and this load model is connected with test power system. The result shows the process of voltage change in time domain when the voltage instability or voltage collapse occurs.

Microstructure, magnetic and transport properties of as-deposited electron-doped $La_{1-x}Ce_xMnO_3$ and hole-doped $La_{1-x}Ce_xMnO_3$ films prepared by pulse laser deposition, with x = 0.1 and 0.3, have been investigated. The microstructural analysis reveals that the $La_{1-x}Ce_xMnO_3$ films have a column-like microstructure and a strip-domain phase with a periodic spacing of about 3c, which were not found for the $La_{1-x}Ce_xMnO_3$ ones. At the same time, the experimental results manifest that there is no fundamental difference in the magnetic and the transport properties between electron- and hole-doped manganite films, except the appearance of ferromagnetic response in the low-doped $La_{0.9}Ce_{0.1}MnO_3$ film at temperatures above the Curie point. The observed magnetic behavior, typical for the Griffiths-like phase, for this film is explained by the percolation mechanism of the ferromagnetic transition and by the presence of strip-domain phase which stimulates the magnetic phase separation.

Many neurologic disorders manifest as psychiatric symptoms. Anti-N-Methyl-D-Aspartate (NMDA) receptor encephalitis is an autoimmune disease of the brain characterized by numerous neurological and psychiatric features. Despite being rare, its prevalence is rapidly increasing and early management is critical in ensuring successful and sustainable recovery. Therefore, the illness should be considered as a differential diagnosis when clinically assessing patients. This report presents a case of a female child who was hospitalized for acute psychiatric manifestations, which was later confirmed as anti-NMDA receptor encephalitis. She recovered relatively successfully after combined neurological and psychiatric treatment. This report provides information on the clinical course of early onset anti-NMDA receptor encephalitis, including treatment strategy and prognosis.

It has long been speculated that the visual system should use a coding strategy that takes advantage of statistical redundancies in images. But how such a coding strategy should manifest in neural responses has been less clear. Low-level image structure related to the power spectrum of natural images appears to be captured by a hard-wired efficient code in the retina of the fly and precortical structures like the LGN of cats that maximizes information content through the limited capacity channel of the optic nerve. But visual images are typically filled with higher-order structure beyond that captured by the power spectrum and visual cortex is not constrained by the same capacity limits as the optic nerve. Whether and how visual cortex can flexibly code for higher order redundancies is unknown. Here we show using psychophysical techniques that the neural response in early human visual cortex may be modulated by orientation redundancies in images such that a visual feature that is contained within a predictive pattern results in slower reaction times than a feature that deviates from a pattern, suggesting lower neural responses to predictable stimuli in the visual cortex. Our results point to a neural response in early visual cortex that is sensitive to global patterns and redundancies in visual images and is in marked contrast to standard models of cortical visual processing.

In the present study, a hybrid model of artificial neural network (ANN) and internet of things (IoT) is proposed to overcome the difficulties in deriving governing equations and numerical solutions of the dynamical behavior of the nano-systems. Nano-structures manifest size-dependent behavior in response to static and dynamic loadings. Nonlocal and length-scale parameters alongside with other geometrical, loading and material parameters are taken as input parameters of an ANN to observe the natural frequency and damping behavior of micro sensors made from nanocomposite material with piezoelectric layers. The behavior of a micro-beam is simulated using famous numerical methods in literature under base vibrations. The ANN was further trained to correlate the output vibrations to the base vibration. Afterwards, using IoT, the electrical potential conducted in the sensors are collected and converted to numerical data in an embedded mini-computer and transferred to a server for further calculations and decision by ANN. The ANN calculates the base vibration behavior with is crucial in mechanical systems. The speed and accuracy of the ANN in determining base excitation behavior are the strengths of this network which could be further employed by engineers and scientists.

The goal of the study was to see how quality management (QMA), strategy (STR), and innovative capability (INC) influence the competitive advantage of a Thai information communication technology (ICT) firm (COA). The researchers collected 431 surveys from Thailand's owners and managers employed in ICT enterprises from the beginning of June 2021 to the end of September 2021using diverse sample strategies. A questionnaire with an index of item-objective congruence (IOC) value of 0.60-1.00 and a reliability value of 0.92-0.96 was used as the research tool. Participants in the survey were requested to fill out a seven-level opinion survey posted on Google Forms. A latent variable structural equation model (SEM) path analysis using LISREL 9.1 was used for the four latent variables, 31 manifest variables, and the five hypotheses testing. The analysis showed that all three causal variables positively affected COA, which had a total effect (TE) R² value = 80% when combined with the other latent variables. Moreover, the values for the latent variables when ranked by total effect (TE) were STR, QMA, and INC with TE values of 0.95, 0.89, and 0.25, respectively. Finally, there were very strong influences from COA to STR (0.95), INC to QMA (0.86), and STR to QMA (0.71).
