The vibration of microtubule in human cells is the source of electrical field around it and inside cell structure. The induction of electrical field is a direct result of the existence of dipoles on the surface of the microtubules. Measuring the electrical fields could be performed using nano-scale sensors and the data could be transformed to other computers using internet of things (IoT) technology. Processing these data is feasible by artificial intelligence-based methods. However, the first step in analyzing the vibrational behavior is to study the mechanics of microtubules. In this regard, the vibrational behavior of the microtubules is investigated in the present study. A shell model is utilized to represent the microtubules' structure. The displacement field is assumed to obey first order shear deformation theory and classical theory of elasticity for anisotropic homogenous materials is utilized. The governing equations obtained by Hamilton's principle are further solved using analytical method engaging Navier's solution procedure. The results of the analytical solution are used to train, validate and test of the deep neural network. The results of the present study are validated by comparing to other results in the literature. The results indicate that several geometrical and material factors affect the vibrational behavior of microtubules.

조선시대 왕실문화는 유교문화의 정수였고, 왕실교육은 유교교육의 최고봉이었다. 수기치인(修己治人)을 실현하는 선비이자 내성외왕(內聖外王)을 구현하는 치자로서, 유교의 이상적인 모델이자, 백성들의 모범이 되어야만 했던 것이 바로 조선의 왕이다. 때문에 왕위계승자들의 교육은 일반 사대부들보다 더욱 엄격하고 치열한 교육과정을 이수해야만 했고, 왕실구성원이었던 왕실자손들의 교육 또한 소홀히 할 수 없었다. 태교는 태아의 건강과 좋은 기질의 형성을 위해 산모가 갖추어야 할 마음가짐과 몸가짐이다. 이는 애초 산모가 보고 느낀 것을 태아도 태내에서 감응한다는 한의학적 학설에 바탕을 둔 것인데, 유교적 수양론과 결부되면서 교육의 시작이요, 성품형성의 근원으로 여겨 교육적으로 매우 중요한 위치를 점하게 되었다. 원자와 원손의 교육과정은 왕위계승교육의 일환으로 국가적인 차원에서 아주 체계적으로 구축되었다. 대개 3세 이전에는 보양청(輔養廳)을 설치하여 보육을 담당하게 하였고, 이들이 글을 읽기 시작할 무렵이 되면 강학청(講學廳)을 설치하여 조기교육을 담당하게 하였다. 이들을 제외한 다른 왕실자손들의 경우, 보양청은 설치되지 않지만 통상 6세가 되면, 종친부 주관으로 대군과 왕자군의 경우에는 강학청(講學廳)을, 왕손의 경우에는 교학청(敎學廳)을 설치하여 조기교육을 담당하게 하였다. 조선왕실 유아교육은 왕위계승자와 왕실자손들 모두 "효경(孝經)" "소학(小學)"과 같은 초학단계를 마치면, "대학(大學)" "논어(論語)" "맹자(孟子)" "중용(中庸)"의 단계적 학습과정을 거치게 되므로 교육과정 자체는 대동소이하다. 그러나 원자의 사부는 정 2품, 원손의 사부는 종 2품이며, 대군과 왕자군의 사부는 종 9품, 왕손의 교부 또한 종 9품으로 규정함으로써 그 위상에 있어서는 현격히 차등을 두어 시행되었음을 확인할 수 있다.

This present paper concerned with the analytic modelling for vibration of the functionally graded (FG) plates resting on non-variable and variable two parameter elastic foundation, based on two-dimensional elasticity using higher shear deformation theory. Our present theory has four unknown, which mean that have less than other higher order and lower theory, and we denote do not require the factor of correction like the first shear deformation theory. The indeterminate integral are introduced in the fields of displacement, it is allowed to reduce the number from five unknown to only four variables. The elastic foundations are assumed a classical model of Winkler-Pasternak with uniform distribution stiffness of the Winkler coefficient (kw), or it is with variables distribution coefficient (kw). The variable's stiffness of elastic foundation is supposed linear, parabolic and trigonometry along the length of functionally plate. The properties of the FG plates vary according to the thickness, following a simple distribution of the power law in terms of volume fractions of the constituents of the material. The equations of motions for natural frequency of the functionally graded plates resting on variables elastic foundation are derived using Hamilton principal. The government equations are resolved, with respect boundary condition for simply supported FG plate, employing Navier series solution. The extensive validation with other works found in the literature and our results are present in this work to demonstrate the efficient and accuracy of this analytic model to predict free vibration of FG plates, with and without the effect of variables elastic foundations.

"Theory on the Sufficiency of Yang and the Deficiency of Yin(陽有餘陰不足論)" mainly instituted as follows: The 'Yang Qi(陽氣)' of the heaven(天) has changed to 'Qi(氣)', and the 'Yin Qi(陰氣)' of the earth(地) has changed to 'Xue(血)', 'Qi(氣)' is always sufficient and 'Xue(血)' is always deficient. 'The Always Sufficient Qi(氣常有餘)' means 'the fire always exists(常有火)', and 'the fire(火)' is 'the premier fire(相火)'. 'The premier fire(相火)' is always in men's body and causes 'activities(動)' which is the core characteristic in men's life, and in other side it always has opportunities to be made symptoms by 'the abnormal activities of the premier fire(相火妄動)'. In 'the always deficient Xue(血常不足)' , 'Xue(血)' is the 'Yin Qi(陰氣)' of liver and kidneys[肝腎] which is attached by 'the premier fire(相火)', as it means 'Xue(血)' and 'Jing(精)'. He suggested that 'the premier fire(相火)' is the power of human life, but if 'the premier fire(相火)' is not based on 'Yin Qi(陰氣)', it can not fulfill its function. So he thought that the maintenance and fulfillment of 'Yin Qi(陰氣)' is very important. In conclusion, "Theory on the Sufficiency of Yang and the Deficiency of Yin(陽有餘陰不足論)" explains the basic character of men's life which 'Dong Duo Jing Shao(動多靜少)', so 'the premier fire(相火)' which control 'the activities(動)' is always being and 'Jing Xue(精血)' which control 'Jing(靜)' is always scare.

In this paper, an efficient shear deformation theory is developed for wave propagation analysis in a functionally graded beam. More particularly, porosities that may occur in Functionally Graded Materials (FGMs) during their manufacture are considered. The proposed shear deformation theory is efficient method because it permits us to show the effect of both bending and shear components and this is carried out by dividing the transverse displacement into the bending and shear parts. Material properties are assumed graded in the thickness direction according to a simple power law distribution in terms of the volume fractions of the constituents; but the rule of mixture is modified to describe and approximate material properties of the functionally graded beams with porosity phases. The governing equations of the wave propagation in the functionally graded beam are derived by employing the Hamilton's principle. The analytical dispersion relation of the functionally graded beam is obtained by solving an eigenvalue problem. The effects of the volume fraction distributions, the depth of beam, the number of wave and the porosity on wave propagation in functionally graded beam are discussed in details. It can be concluded that the present theory is not only accurate but also simple in predicting the wave propagation characteristics in the functionally graded beam.

Unit distributions are frequently used in probability theory and statistics to depict meaningful variables having values between zero and one. Using convenient transformation, the unit inverse exponentiated weibull (UIEW) distribution, which is equally useful for modelling data on the unit interval, is proposed in this study. Quantile function, moments, incomplete moments, uncertainty measures, stochastic ordering, and stress-strength reliability are among the statistical properties provided for this distribution. To estimate the parameters associated to the recommended distribution, well-known estimation techniques including maximum likelihood, maximum product of spacings, least squares, weighted least squares, Cramer von Mises, Anderson-Darling, and Bayesian are utilised. Using simulated data, we compare how well the various estimators perform. According to the simulated outputs, the maximum product of spacing estimates has lower values of accuracy measures than alternative estimates in majority of situations. For two real datasets, the proposed model outperforms the beta, Kumaraswamy, unit Gompartz, unit Lomax and complementary unit weibull distributions based on various comparative indicators.

The free vibration of temperature-dependent functionally graded plates (FGPs) resting on a viscoelastic foundation is investigated in this paper using a newly developed simple first-order shear deformation theory (FSDT). Unlike other first order shear deformation (FSDT) theories, the proposed model contains only four variables' unknowns in which the transverse shear stress and strain follow a parabolic distribution along the plates' thickness, and they vanish at the top and bottom surfaces of the plate by considering a new shape function. For this reason, the present theory requires no shear correction factor. Linear steady-state thermal loads and power-law material properties are supposed to be graded across the plate's thickness. Uniform, linear, non-linear, and sinusoidal thermal rises are applied at the two surfaces for simply supported FGP. Hamilton's principle and Navier's approach are utilized to develop motion equations and analytical solutions. The developed theory shows progress in predicting the frequencies of temperature-dependent FGP. Numerical research is conducted to explain the effect of the power law index, temperature fields, and damping coefficient on the dynamic behavior of temperature-dependent FGPs. It can be concluded that the equation and transformation of the proposed model are as simple as the FSDT.

This survey paper examines general characteristics of "yellow" color, the oldest color in the history of art. Also the research aims to find meanings of the color and historical development embedded in clothing and textile both in orient and in occident where different philosophy and history developed. It is found here that the yellow symbolized both positive and negative meaning in the history of costume throughout the world. The color, however, was used to symbolize mostly positive meaning in the orient whereas not in the occident. "Yellow" color in orient used to symbolize the supremacy of the emperor, excellence and authority. The meaning of "yellow" color in the occident is two fold: from the positive viewpoint it represent god, king, wisdom, wealth and holy light, and from the negative viewpoint it represent image of betrayal and distrust, image of immorality, image of death and disease and image of jealousy and hatred. The concept of "yellow" was generalized in orient by the "Eum-Yang-O-Haeng Theory", while in occident by the Christianism. And the concepts came to hold concrete meanings and thereafter the symbol of yellow appeared.ings and thereafter the symbol of yellow appeared.

This paper investigates the effect of the involvement of the board chairman in the audit committee (AC) on earnings management (EM). It examines Bursa Malaysia-listed companies with the lowest positive earnings for the years 2013 to 2015. The Modified Jones Model by Kasznik (1999) was used to determine discretionary accruals. An AC that includes its board chairman as an ordinary member is associated with greater discretionary accruals. However, a board chairman who is also the chairman of the AC does not seem to influence discretionary accruals. This paper supports the agency theory and policy-makers' efforts to prevent board chairmen from sitting on ACs. It is the first study that uses the agency theory to describe the association between the board chairman's involvement in the both AC and EM. This study alerts policy-makers, stakeholders and researchers to the influence of a board chairman serving on the AC in curbing EM. Furthermore, it provides empirical evidence that the majority of Malaysian companies whose board chairmen are involved in the AC appoint the chairman as an ordinary member of the AC. This indicates that executive directors may affect such actions. Hence, more policies are needed to improve AC independence.
