In recent years, the Internet was a lot of information on the use of Tesla coils bifilar [1] in conjunction with induction cooker, for "free" electricity during power resistive load, including different incandescent lamps. With the development of scientific and technological progress, the demand for electricity in each year is increasing, and at the same time, the need to increase the capacity of electricity production, which entails large investments and, consequently, increase of prices for consumers. As before today, the search for free electric energy is an up-to-date and still open topic. The purpose of research - simplification of information on the possibility of using bifilar coils as an electric current source in conjunction with induction cooker. Consequently, it can be concluded from the above that the use of Tesla coils in combination with induction cooker has very low k.k.d. and it is not possible to obtain excessive electric energy using the Tesla coil under the connection schemes considered.

Most of rural bridges have passed 30 years of age since they were built, which have to support unexpected overload caused by changed design load and excessive amount of transportation. For these rural bridges, repairs and replacements are needed. Even though there have been attempt to estimate the safety of existing bridges deteriorated with major defects, those approaches must rely on the observable damage and subsequent decisions are made subjectively. To avoid the high cost of rehabilitation, the bridge rating must correctly represent the present load-carrying capacity. Rating engineers use a methods such as Allowable Stress Design (ASD), Load Factor Design (LFD), and Load Resistance Factor Design (LRFD) to evaluate the bridge load carrying capacity. In this paper, the load rating methods are introduced, and it is illustrated how to use the load test data from literature survey. Load test is conducted to the bridge that was built 30 years ago in rural area. From load test results, new maintenance method is suggested instead of the bridge replacement.

The use of high amylose maize varieties significantly affected the alkaline-cooking process and characteristics of alkaline-processed food products, such as masa and tortilla chips. High amylose maize varieties had softer endosperm textures with move tightly attached pericarps than normal maize. Masa prepared from high amylose mutant maize was less cohesive than that of normal maize due to insufficient dispersion of amylopectin and excessive retrogradation of starches. Tortilla chips prepared from amylose-extender dull (ae du), amylomaize V, and Ⅶ had slightly increased oil absorption, while tortilla chips from dull (du) and amylose-extender sugary-2 (ae su-2) had oil contents similar to that of control chips. Increased oil absorption of the tortilla chips was due to their increased surface area. Tortilla chips produced from high amylose mutant maize had darker color than control chips, presumably due to the pigmented pericarp tissues, higher levels of reducing sugars, and phenolic compounds present in the kernel.

This paper presents an efficient algorithm for loss reduction of distribution system by automatic sectionalizing switch operation in large scale distribution systems of radial type. Simulated Annealing algorithm among optimization techniques can avoid escape from local minima by accepting improvements in cost, but the use of this algorithm is also responsible for an excessive computation time requirement. To overcome this major limitation of Simulated Annealing algorithm, we may use advanced Simulated Annealing algorithm. All constaints are divided into two constraint group by using perturbation mechanism and penalty factor, so all trail solutions are feasible. The polynomial-time cooling schedule is used which is based on the statistics calculation during the search. This approaches results in saving CPU time. Numerical examples demonstrate the validity and effectiveness of the proposed methodology.

과도한 SNS활동과 스마트폰 사용은 중독과 함께 수면장애로 이어지고 있다. 특히 침대 이동 후 잠들기 전까지의 스마트폰 사용시간이 길어지면 길어질수록 수면 부족, 장애 현상이 나타났으며, 이는 청소년 언어, 행동 폭력성에 영향을 미치는 것으로 나타났다.

Tall buildings are subjected to wind loading that can cause excessive wind-induced vibration. This vibration can affect the activities of the inhabitants of a building and in some cases fear for safety. Many codes and standards propose the use of curves of perception of acceleration that can be used to verify the serviceability limit state; however, these curves of perception do not take into account the uncertainty in wind-climate, structural properties, perception of motion and maximum response. The main objective of this study is to develop an empirical expression that includes these uncertainties in order to be incorporated into a simple procedure to evaluate the wind-induced acceleration in tall buildings. The use of the proposed procedure is described with a numerical example of a tall building located in Mexico.

The goal of the study was to see how polymer banknotes affected users' purchasing intention. Variables affecting the properties of polymer banknotes were considered, including security, ease of use, convenience, and durability. To achieve the study's main goal, quantitative methods were used, and a questionnaire was created and posted online through Google Forms to collect primary data. The questionnaire was completed by 403 people, and the data was screened and analyzed using SPSS.The study found that using Polymer money influenced people's behavior, particularly in terms of purchase patterns, decisions, and impulsive behavior toward purchases. This was attributed to the security and simplicity of using Polymer money, which appealed to many people. Furthermore, the study found that people lost their feeling of spending, meaning that using polymer money didn't feel like spending to them, effectively eliminating the moral guilt associated with excessive spending and encouraging more impulsive buying decisions.Based on the findings, the study recommends that a study be conducted to compare the use of Polymer money with tiny and large banknotes to see what kind of difference there is.

In digital marketing, the strategic use of emojis in social media advertising, particularly on the Xiaohongshu app, significantly influences consumer acceptance and purchase behavior. This study examines the impact of emoji-laden advertisements and the role of brand metaphorical warmth on consumer perceptions. Employing a tailored questionnaire, the research explores how emojis affect brand advertisement reception, filling a gap in empirical research on emoji advertising effectiveness. Findings indicate that emojis, when used judiciously, enhance consumer acceptance and contribute to a positive brand perception. However, excessive use may undermine trust. Brand metaphorical warmth emerges as a crucial factor, suggesting that emojis can effectively convey warmth, fostering a deeper emotional connection with consumers. These insights offer practical implications for refining social media marketing strategies, advocating for a balanced approach to emoji usage in advertisements to optimize engagement and influence consumer behavior.

치관높이 공간이 과도할 경우 임플란트 몸체 혹은 구성물의 실패와 같은 고정성 보철물의 생역학적 합병증이 증가하며 치관 높이 공간이 12 mm 이상으로 과도한 경우는 고정성 보철물 선택에 유의하여야 한다. 고정성 보철물을 제작 시 치아들이 길어지므로 심미적 부위에서는 치은 색조를 띠는 재료를 사용해야 할 필요가 있다. 이러한 경우, 유지와 위생 관리가 적절하지 못하게 형성된 고정성 보철물은 음식물, 치태, 치석을 정체시키고 염증과 감염이 발생될 수 있으며 만성 염증과 감염으로 인해 외과적인 개선이 필요할 수 있다. 본 증례에서, 과도한 치관높이 공간을 가진 환자에게 발음 및 심미성을 고려하여 보철물 제작 후 보철물 주위의 치은 염증 및 부종이 발생하였으며, 그 원인이 구강위생을 어렵게 하는 보철물의 디자인으로 판단되어 치간공극을 충분히 형성한 임시 보철물을 장착 후 2개월 동안의 관찰 기간을 거치며 특이할 만한 이상 소견이 없음을 확인하였고 자가 위생 관리가 용이한 디자인으로 지르코니아 하부구조에 도재를 축성한 고정성 보철물로 구강회복을 시행하였으며, 일련의 치료과정을 통하여 부적절한 연조직 반응이 관찰 되지 않고 기능적인 면에서 만족스러운 결과를 얻을 수 있었다.
