Semantic fields in Surat Al-Waqi’ah

From the research it was found that the meaning of the words mentioned in Surat Al-Waqi’ah is not scattered words; Rather, it is based on classification based on fixed indicative fields. The research showed that the meanings of these words are becoming clearer in their semantic field assigned to them, and the words are organized into fields that combine common features; Because the meanings of these terms in the dictionary are separate and far between, and in their semantic fields they are classified and arranged. The research proved that the meanings of the words have relations and connections within the same semantic field, whether it is a relationship of similarity, a relationship of difference, or a relationship of contrast. The research showed that semantic fields theory is suitable to be an approach that contributes to analyzing the significance at the same linguistic level in an accurate and accurate way, as it makes the process of revealing the relationships between words easy and easy. The research revealed the profound connection between the words mentioned in Surat Al-Waqi’ah and their meanings, as the words do not live in isolation from each other, thus dropping the saying in the arbitrary theory in the language that some of the modernists called for. The research proved that semantic fields theory constituted a generous time in revealing the relationships between the meanings of words in the single semantic field.The research proved that semantic fields theory existed with the ancients, which was abundant with previous heritage and linguistic books, and it is an ancient Arab practice, even if it lacks the term and title such as (the book) and the book (Jurisprudence of Language and the Secret of Arabic) as well as many other books that are concerned with the classification of words according to Their meanings, arrangement and type of relationship. The research showed that the semantic relationships between the words mentioned in Surat Al-Waqi’ah are classified within the fields of strength, vibration, concussion, lowering and elevation, and this is clear from the name of the surah, which is the event, i.e. the Day of Resurrection after people are resurrected again.

Special Issue on Wearable Robotics and Mechatronics Technology

Many wearable devices have been developed and are being currently used, owing to the miniaturization of computers and electronic devices and advancements in calculation processing algorithms. They have various uses and forms, for example, a power assist robot for reducing the burden of work, a wearable sensor for measuring the level of activity and health condition of people and animals, and so on. In Japan, wearable devices have attracted attention as an important technology in a human-centered society (Society 5.0) and can help realize economic development and address social problems. A society that can benefit from a wide range of wearable devices is being realized. This special issue covers robotics and mechatronics technologies for next generation wearable devices to realize such a society, including wearable systems and their elemental technology, AI, IoT, and other relative technologies. We sincerely thank the authors for their fine contributions and the reviewers for their generous time and effort. We would also like to thank the Editorial Board of the Journal of Robotics and Mechatronics for their help with this special issue.

Special Issue on Gear Components and Actuators

Components such as gears, bearings, and shafts are essential to effective automation, ensuring reliable, cost-effective design. Actuators such as DC, AC, and stepping motors are equally important to automation. Studies in mechatronics make equal use of both gears and actuators in the practical construction of automated equipment. This special issue on gears and actuators looks at studies on load bearing capacity in mechanical system design, including micropitting generation and high-speed finishing of hard gear teeth for garnering insights into mechanisms behind successful automation. It also monitors the study of trajectory planning and motion control of robots using ball screws, worm gears, stepping motors, and AC motors. Our deep appreciation goes to the authors for their informative and interesting papers and to the editors for their generous time and effort in making this special issue possible.

The Primacy of Politics

In presenting my valedictory to this distinguished Association which has honored me by selecting me as its President, I should like to point out by way of introduction what has happened to this office, and therefore to me, during the past year. I have heard of one of my distinguished predecessors some twenty-five years ago who had little else to do as President of this Association than work all year on his presidential address. This was important work and I have no word of criticism of it. But the Association has changed, and today it leaves to the harried wearer of its presidential toga little time to reflect about the status of political science and his own impact, if any, upon it. An active Association life, now happily centered in our new Washington office, is enough to occupy the full time of your President, and universities as well as this Association might well take note. Therefore, in presenting my own reflections to you this evening in accordance with the custom of our Association, I do so without the benefit of the generous time and scholarly leisure which were the privileges of some of my distinguished predecessors.Nevertheless I do base my presidential address today upon my own active participation in the problems of government, as well as upon my scholarly experience. I have extracted it in part from the dynamics of pulsating political life. It has whatever authority I may possess after having been exposed these twenty-five years to the cross-fire of politics, domestic and foreign, as well as to the benign and corrective influences of eager students and charitable colleagues.
