  • The optimization in the machining process has been a long-standing goal of the manufacturing community. The optimization is composed of two main subjects;one is to select an optimum cutting condition, and the other is to detect the emergency situation and take necessary actions in real-time base. This paper proposes a reliable and practical guide system whose purpose is the optimization of cutting conditions, and the detection of tool failure in the machining process. The optimal cutting conditions are determined through the estimation of tool wear rate and the establishment of access- ible field from the measured cutting temperature and force. Tool breakage is detected by the normal force component acting on minor flank face extracted from on-line sensed feed force and radial force. In experiments, the proposed guide system has proved availability for the decision of reliable cutting conditions for the given tool-work system and the detection of tool breakage in ordinary cutting environments.

  • Purpose - Following globalization, Kazakh companies are considered to be among the main economic agents of the country. The influence of Limited Liability Partnerships (LLPs) on Kazakhstan's economic development is becoming increasingly pronounced. Therefore, limitations and backwardness of legislation regarding regulation of corporate governance must be overcome at the earliest. Research design, data, and methodology - We considered the basis for legislation of corporate governance in Kazakhstan, and the corporate governance models that better describe the situation of being in the organization. Results - Earlier studies have identified several problems, including "transparency" of issuers and markets, and the consequent lack of (undeveloped) external control of managers of the former state-owned enterprises; lack of traditional corporate ethics and culture; and corruption, and other criminal aspects of the problem. This article describes several proposals to improve corporate governance in Kazakhstan to solve these problems. Conclusions - Domestic reformers acting without consideration of local features is a common occurrence today. They often ignore that these features are recommended for reputable international organizations, and therefore should be used carefully.

  • Influence of form errors of a chamber filled with a liquid on the movement and stability of a ball, rotating in the chamber, is studied. Two cases of the influence of the chamber form errors on the forces, acting on the ball, are defined. The first case describes the situation when limitations on the rotor shift are not imposed and disturbances of the chamber form are set by spherical harmonics not above the first order. In the second case disturbance of a chamber form is arbitrary and the rotor is supposed small. A rising here diflective moment tends to direct the angular speed vector along the small semiaxis of the ellipsoid, i.e., a stable position of the rotor appears.

  • The torsional or axial critical vibration of the order coinciding with the number of propeller blades is simultaneously excited by the harmonic tangential or radial forces acting on the crank shaft and by the harmonic of the same order from the propeller. The exciting torque of propeller is relatively small comparing with that of crank side, but the exciting force of propeller rather larger than that of crank shaft. With this situation, the exciting force of propeller cannot neglect if the axial vibration of propulsion shafting is calculated. With the propeller in its optimal angular position, i.e. its excitation effect opposed to that of the engine, the stresses at the critical revolution will largely cancel themselves out. In this paper, a method of optimizing the angular propeller position with regard to torsional and axial vibration is studied. The optimal relative angle is determined theoretically by calculation results of coupled torsional-axial vibration.

  • As the technology of industrial automation using robot system grows the rapid advance, productivity improvement and decrease in number of maintenance, management occur in many fields. Therefore, more various and intelligent robot motions are needed without human being help. Considering this situation, the need of robot with various, fast and safe acting sensors are demanded. In these sensings, the slippage sensing gives us specific information between ripper and object while grasps the object. In this paper, we proposed new slippage sensing algorithm for various and intelligent robot motion. So, optimal grasping force control and compensation of position error is possible for an adaptive task execution using adaptive control.

  • Since 1903, the International Dairy Federation (IDF) has been providing information on policies, standards, and regulations of the dairy industries to reach a global consensus on how to help feed the world with safe and sustainable dairy products. The 2021 IDF Global Dairy Conference was held in Copenhagen, Denmark with the theme of 'A Changing Climate for Dairy' for three days from the 13th to the 15th of October. Over 350 worldwide participants came together were expected to come together with several hundred additional online participants. An interesting topic among those presented at the conference was artificial milk at the Processing & Technology session on October 14th. Dr. Eisner presented "Milk by Fermentation", in which he presented the technique of culturing and manufacturing artificial milk, based on artificially producing the caseins and enzymes through precision fermentation, which is suitable for making artificial cheeses. During the conference, the IDF launched the latest edition of the publication on global dairy markets, titled the World Dairy Situation Report 2021. According to report, South Korea is ranked 3rd in the world for cheese imports.

  • This paper presents a simulation for passenger ship evacuation considering the inclination of a ship. In order to describe a passenger's behavior in an evacuation situation, a passenger is modeled as a rigid body which translates in the horizontal plane and rotates along the vertical axis. The position and rotation angle of a passenger are calculated by solving the dynamic equations of motions at each time step. To calculate inclined angle of damaged ship, static equilibrium equations of damaged ship are derived using "added weight method". Using these equations, physical external forces due to the inclination of a ship act on the body of each passenger. The crowd behavior of the passenger is considered as the flock behavior, a form of collective behavior of a large number of interacting passengers with a common group objective. Passengers can also avoid an obstacle due to penalty forces acting on their body. With the passenger model and forces acting on its body, the test problems in International Maritime Organization, Maritime Safety Committee/Circulation 1238(IMO MSC/Circ.1238) are implemented and the effects of ship's inclination on the evacuation time are confirmed.

  • The poor welfare level of social workers is a big social problem in direct proportion to the ongoing need for social welfare service. In particular, the emotional work of social workers is a serious situation. This Study examines the effect of emotional labor(EL) on customer orientation(CO) of social workers with case management. Also this paper investigates the moderating effect of emotional intelligence(EI) and leader-member exchange(LMX). The major results from the study are as follow: First, we found that surface acting(SA) of EL had a negative impact on CO and deep acting(DA) of EL had a positive impact on CO. Second, EI showed a moderating effect on the correlation between SA of EL and CO. Also, EI had the moderating effect that weakening the negative impact of SA on CO. Third, LMX showed a moderating effect on the correlation between DA of EL and CO. Also, LMX had the moderating effect that strengthening the positive impact of DA on CO. In particular, this study presented with implications for future research, limitations of this study.

  • Geugyesuryeonguhoe founded the Silheommudae and chose Nikolai Vasilevich Gogol's Revizor as the founding performance. This Revizor theater performance was a performance equivalent to the founding performance of the Geugyesuryeonguhoe, so it had to be based on the discussion and consensus of the members. Nevertheless, the reasons for selecting this work, the actual performance situation, and whether or not it was successful were not properly addressed in the research data so far. As a result, Revizor performance of Silheommudae did not escape the powerful influence of Revizor theater performance performed at Tsukiji(築地) theater in Japan. In addition, the original design of stage, acting and acting concept of Silheommudae was not confirmed. After this performance, the change of the performance method of Geugyesuryeonguhoe was inevitable. And Geugyesuryeonguhoe was forced to carry out its own reflection on the problems in the stage process.

  • This article examines how Brecht's Gestus is borrowed and transformed into the film. I examined the critical debates on the film's use of Brecht and the style of Brecht's acting adopted in radical experimental films and Hollywood films. In addition, through the case of Korean film actor/ress, I sought to apply the Brechtian theory. First, despite the criticism that the film's acceptance of Brecht is overly formal and mechanical, film theory and practice reflect Brecht's ideas. In particular, regardless of the socio-political situation of Brecht's day, his Gestus is suitable and useful for film acting. Brecht's thought was realized by technological innovations such as montage and computer special effects, and above all, the social attitude of the actor was popularized through the education of the audience. Second, his strategy on performance is no longer unfamiliar, and goes beyond the boundaries of contradictory daily life and art, and becomes the pleasure of popular film. Although the intentions of naturalism and anti-naturalism in acting arts are different, the process and effects look at the same point. Third, through the case of Korean film actor/ress as an attempt of popular understanding about Brecht strategy, I could confirm the possibility of searching identity of Korean film actor/ress.
