Skin is the largest organ of the human body and a physiological structure that is directly exposed to the environment. From a theoretical perspective, numerous physiological and psychological signals use the skin as a medium for input and output with the outside world. Therefore, the skin is considered an optimal signal interception point when developing noninvasive, direct, and rapid signal exploration devices. To date, skin signal interceptions are predominantly performed by measuring skin impedance. However, this method is prone to interference such as sweat secretion, salt accumulation on the skin, and muscle contractions, which may result in a substantial amount of interference and erroneous results. The present study proposes novel and effective methods for skin signal interception, such as using a nested probe as a sensor to measure capacitance to be further processed as physiological and psychological signals. The experimental results indicate that the capacitance curve for the transition between wakefulness and dozing exhibits significant changes. This change in the curve can be analyzed by computer programs to clearly and rapidly determine whether the subject has entered the initial phases of sleep.

<p><span lang="EN-US">Writing this article backed by mult</span><span>i</span><span lang="EN-US"> interpretation problems raised by a text, especially literary texts. Mult</span><span>i</span><span lang="EN-US"> interpretation is inseparable from the consciousness and unconscious of the subject of the author, as well as the process of reconstruction by the reader. Based on this article this article aims to describe the results of deconstructing binary opposition readings on the story of <em>Kritikus Adinan</em> by Budi Darma. The data source used is the story of <em>Kritikus Adinan.</em> The research method used is descriptive analysis with the theoretical perspective of deconstruction of Jaques Derrida. Based on the findings and data analysis, the results show the following. <em>First</em>, the deconstruction readings of the <em>Kritikus Adinan</em> can not be separated from the word-scoring process as Jaques Derrida puts it in deconstruction theory. <em>Secondly</em>, the reconstruction of Kritkus Adinan’s story leads to unfamiliarity but leads the reader to discover the marginalized texts.<em> Third</em>, based on the results of deconstruction reading in the story of <em>Kritikus Adinan</em>, there is a binary opposition that has been denied and broken by the author by presenting a reversal of fact.  Suggestions that can be recommended are many other literary works that are worthy and important to be reviewed by other researchers to uncover the phenomenon of reversing the facts by the author.</span></p>

Globally, housing policies have been used as an attempt to try and address housing problems, particularly in respect to the low-income earners, with the view of helping them access better housing. The evolution of housing policy in developing countries has been studied and identified in different ways, however, this paper present a robust theoretical background of the developments in housing policy framework. The data used in this paper were derived from secondary sources only; through a detailed review of related literature on the subject to meet the research objectives. The study is an in-depth literature exploration of the theoretical perspective of the housing studies framework. The literature reviewed found that the theory of housing had its origin in the Paleolithic period when homo-sapiens began to use natural materials like stone, wood, leaves, animal skin and other similar items to create shelter from elements of weather. It was also found that there are various theoretical perspective frameworks that have been used in the study of housing, such as political, social, developmental, institutional, and radical perspectives amongst others. This study provides a robust theoretical framework used in housing study.

One of the salient features of the Korean language is honorifics. Two kinds of honorifics have been discussed in the literature, subject honorific and addressee honorific. The subject honorific is characterized by honorific markers on the subject and predicate. The addressee honorific is usually marked by formal and/or polite speech style particles at the end of a sentence. The subject honorific is characterized by its optionality which has raised many questions about its nature, whether it is a type of formal feature agreement or not. The addressee honorific, however, has not received much attention from a theoretical perspective in the literature though much descriptive work is available. In this paper, we attempt to discuss the optionality of subject honorific in the context of the nature of honorifics in general, including the addressee honorific. More specifically, we examine how honorific is encoded in the grammar by focusing on embedding of honorifics. Some empirical data show that embedding of honorifics (or politeness) is restricted in certain constructions. Based on examining these constructions, we claim that there is a generalization that prohibits the occurrence of honorific/politeness marker in the embedded CP domain. We further claim that this restriction interacts with subject honorific in such a way that it forces the agreement of honorific to take place obligatorily in certain constructions, thereby making the optionality of the subject honorific to hold only conditionally and circumstantially.

Water is one of the most essential needs for life. About 0.3% of the water resources in the world are usable. Water shortages already exist in many regions, with more than one billion people without adequate drinking water. This situation is one of the most important indicators of why we should be very sensitive and conscious towards our water resources.As the world population increases need water also increases.However, as a result of different effects and especially human activities, water resources are decreasing, polluted and still used unconsciously.Water use has doubled increased between the years 1940-1980 and is faced with the danger of water shortages in many countries such as Turkey.Therefore, it is necessary to take and implement measures as soon as possible and we have to use water resources carefully. The aim of this study is to review the literature on the subject, to better understand the importance of water and to evaluate the issues such as preventing water pollution and waste from a theoretical perspective.

Recent research has been used to identify efficiency improvements that may be obtained by utilizing on-off hydraulic valves in the place of traditional hydraulic valves. These efficiency improvements reduce throttling losses in the valve by using wide-open valve positions that are intermittently turned on and off. While this efficiency idea has emerged with great interest among some, there are still those who remain doubtful about the efficiency improvements that have been claimed and anecdotal concerns continue to be voiced at conferences and in hallway discussions within industry. This paper is being written to address the subject from a theoretical perspective. In the analysis of this paper, the efficiency equations for an on-off valve will be derived and compared to the efficiencies of valves that are employed in pressure relief systems, pressure compensating systems, and load sensing systems. In conclusion, it is shown that valves operating in load sensing systems are always the most efficient valves, while digital valves are often the next most efficient design except during low flow conditions when the valve in a pressure compensating system may occasionally be more efficient than the digital valve. It is shown in this research that valves used in pressure relief systems are always the most inefficient design.

It is possible to obtain a continuous record of the sweating rate of an active subject by monitoring changes in total body weight. However, elaborate equipment is required that is capable of accommodating the treadmill (or other exercising device) as well as the subject. The balance must be rugged enough to withstand the movements of the subject, yet sensitive enough to respond to small changes in weight. It would be a great convenience to be able, instead, to monitor small representative areas of the skin surface with confidence that they faithfully reflect whole body reactions.In this research, moisture loss from a representative area of the skin of the dorsum under a capsule covering 14 sq. cm was measured by an apparatus which automatically altered the flow of dry air to keep the humidity of the effluent constant. In four subjects exercising on a treadmill at 3.5 m.p.h. the correlation coefficient between the area under the curves so obtained and the total body weight loss was very high (more than 0.93), and there was also good correlation after sweating was partially suppressed by atropine. Short-period fluctuations were simultaneous and highly correlated between bilaterally symmetrical areas of skin. It is concluded that moisture loss from a single area of skin can be used to represent changes in the rate and pattern of sweating of the whole body.

Ensuring that students reach the determined goals of the courses at the desired level is one of the primary goals of teaching. In order to achieve this purpose, educators use a variety of teaching strategies and methods, and teaching materials appropriate to the content and the subject of the courses in the teaching process. As a matter of fact, it is known that the methods and materials that appeal to different sense organs of the students influence the learning process positively. In addition, the use of various teaching methods, techniques and materials in the teaching process both attract students’ attention and save the lesson from boredom, which affects the learning positively. In the process of teaching students sometimes have problems using their theoretical knowledge in real life situations. In this context, various teaching methods are also used for the practicalization of theoretical knowledge in the teaching processes. The case study method is one of the effective methods to achieve this purpose, because the case study method is a teaching method that enables students to acquire the knowledge and skills to deal with the problem they are working on and to produce information-based solutions in real life situations similar to the situations they are working with. In this study, the literature related to the case study method was examined and the application of the method, its history, application types, points to be considered in the application process, advantages of using the method in the teaching process and its limitations and teaching techniques to be used with the method are explained.

The occurrence of a general cutaneous eruption consequent upon vaccination, that is to say the inoculation of vaccine virus upon an abraded skin surface, is a possibility generally recognised. But the meagre literature of the subject, and the scanty and brief references in present-day text-books of medicine indicate that the condition is only occasionally encountered.

One of the few exceptions to the principle of the immediate execution of a penalty, expressed in Article 9 § 1 of the Executive Penal Code, is the institution of its deferral. The conditions of its application are specifi ed in the provisions of Article 150 and Article 151 of the Executive Penal Code. Postponement of a custodial sentence is not absolute, because the occurrence of certain factual or legal conditions during its duration may result in its termination. The subject of the article is to analyse the grounds for ending the postponement of a custodial sentence, with particular emphasis on the institution of appealing the postponement, and modifi cation of the decision pursuant to Article 24 of the Executive Penal Code. The study uses the method of dogmatic analysis, emphasizing, albeit with diff erent intensity, elements such as: description and systematization of legal norms, their interpretation as well as establishing and defi ning concepts. In the opinion of the author, the issue of the grounds for ending a postponement of a custodial sentence is, on the one hand, an attractive area of scientifi c research from a theoretical perspective. On the other hand, it is an important problem faced in the practice of judicial authorities. It is also a subject to which science seems to devote too little attention. Such a state of aff airs undoubtedly determines the need for scientific of the subject under consideration. Its results allow for the conclusion that the current legal regulation requires correction, the direction of which, by indicating the proposed changes to the applicable regulations, is presented by the author in this study.
