With the 4th industrial revolution, condition monitoring using machine learning techniques has become popular among researchers. An overload due to complex operations causes several irregularities in MOSFETs. This study investigated the acquired voltage to analyze the overcurrent effects on MOSFETs using a failure mode effect analysis (FMEA). The results indicated that the voltage pattern changes greatly when the current is beyond the threshold value. Several features were extracted from the collected voltage signals that indicate the health state of a switched-mode power supply (SMPS). Then, the data were reduced to a smaller sample space by using a principal component analysis (PCA). A robust machine learning algorithm, the support vector machine (SVM), was used to classify different health states of an SMPS, and the classification results are presented for different parameters. An SVM approach assisted by a PCA algorithm provides a strong fault diagnosis framework for an SMPS.

The growth of the AR/VR market due to the advent of the 4th Industrial Revolution begins with the development of the display industry. The development of OLED and flexible displays is further accelerated by the development of R2R technology. Micro-processing technology using a fast tool servo (FTS), the core technology in R2R processes, is making technological progress in increasingly diverse ways. This paper proposes a method to develop an FTS for horizontal driving and presents this method through experiments and analyses. To develop a swing-type FTS based on a seesaw motion, a rotational moment hinge structure was designed for each type, and research was conducted to determine an effective design method. A cantilever-based swing-type FTS was developed in two variations: one with single-side hinges and another with dual-side hinges. The parameters in the design of the swing-type FTS are rotational moment, natural frequency, and material selection. In conclusion, an FTS with a single-side hinge demonstrates the high performance required for micro processing.

Practical science means open and objective attitude as a new scholarly tone which gets out of Confucianism tradition and its closeness. It is concerned about practical aspect and its thought prevailed from the mid-16th century to the mid-19th century in feudal system. It is, also, the attitude seeking truth based on the facts, which is removed from the falsehood in politics, economics and social life. It is regarded as a social revolution which governs tile country economically and is utilized to stabilize and enrich a human living life. The new academic tradition appeared in the process of development of modernization proclaimed it to be utilized in modern-oriented independency. Modern historians have greatly studied the knowledge of early philosophy, while Korean oriental medicine has developed, basing on the cultivation of the mind, virtue, and benevolence through Han Bak-Keun(who showed much interest in realistic, economic and social system) and Jung Yak-Youg(who compiled all available data into one book). From Ko-Ryo dynasty to the mid-Yi dynasty Korean oriental medicine scholars struggled to develop oriental medicine in an attitude searching truth based on the facts. Among them Huh Jun's achievements and the content of his writings suggest any things with a view of practical science. These are neglected by most scholars so far, but I have surveyed as follows : 1) the revolution in oriental medical science system 2) the standardization of pharmacy appliance 3) the popularization of medicine supplies 4) cooperation of industry and academy in medical science field From the above I concluded as follows : practical science in Korean medical science began from Ko-Ryo dynasty and compiled in Ku Am Huh Jun in the period of King Sun-Jo of Li dynasty. With this repect, the pioneer in practical science in Korea is Ku Am Huh Jun. To search tile pioneer in practical science rightly we should study the history of Korean medical science.
