At present, the Colombian government shares information on threats or vulnerabilities in the area of cybersecurity and cyberdefense, from other government agencies or departments, on an ad-hoc basis but not in real time, with the surveillance entities of the Government of the Republic of Colombia such as the Joint Command of Cybernetic Operations (CCOCI) and the Cybernetic Emergencies Response Team of Colombia (ColCERT). This research presents the MS-CSIRT (Management System Computer Security Incident Response Teams) methodology, that is used to unify the guidelines of a CSIRT towards a joint communication command in cybersecurity for the surveillance of Information Technology (IT), Technological Operations (TO), Internet Connection Sharing (ICS) or Internet of Things (IoT) infrastructures. This methodology evaluates the level of maturity, by means of a roadmap, to establish a CSIRT as a reference framework for government entities and as a guide for the areas of information security, IT and TO to strengthen the growth of the industry 4.0. This allows the organizations to draw a line of cybersecurity policy with scope, objectives, controls, metrics, procedures and use cases for the correct coordination between ColCERT and CCOCI, as support entities in cybersecurity, and the different companies (ICS, IoT, gas and energy, mining, maritime, agro-industrial, among others) or government agencies that use this methodology.

Caregiving for the children seems to be one of the most challenging tasks for the parents who should devote themselves totally despite endangering them. From the evolutionary perspective, this human behavior must have been the advantage in the survival of the species and rooted in ethological origin. John Bowlby, a child psychiatrist, psychoanalyst, and great developmental researcher, had formulated the attachment theory linking psychoanalysis and ethology through evolutionary biology. His and later following researchers' outcomes have provided enormous influence on viewing parental caregiving and the insight of human relationships and interventions. This article overviews the attachment theory in terms of the goal oriented cybernetic system to gain the survival advantage of the offspring and investigates the evolutionary origin of the caregiving and attachment from the retiles of the Mesozoic era to the mammalian revolution and finally to the human being. Deeper understanding of the nurturance and adult relationships from the standpoint of evolution can provide clinical utility of awareness of clients' lives.

The paper describes system design of next-generation Ship Simulator using Virtual Reality (VRSS), well known as human-computer interaction. VRSS system is required to have special condition that comprises multiple user participants such as captain, officer, pilot, and quartermaster. To cope with that condition, core technologies were explored and proposed multi-networking system with broker server. The evaluation of the proposed system was done with PC-based immersion-type VR device, constituted with HMD (Head Mounted Display), Head Tracking Sensor, Puck, Headphone, and Microphone. Using the VR device, assessment test was carried out in a virtual bridge with 3D objects, which are created by VRML (Virtual Reality Model Language) program. As results of tests, it is shown that the cybernetic 3D objects were act as if real things in a real ship's bridge. Therefore, interesting interaction with participants can be obtained in the system, Thus, we found that the proposed system architecture can be applicable to VRSS system construction.

In this paper, an intelligent control scheme with multi-stage fuzzy inference is developed for a myoelectric prosthesis to achieve natural control with tactile feedback based on fuzzy control strategies. Strain gauges and a potentiometer are added to the prosthesis for tactile feedback with a PWM motor driver developed to save the battery power. According to the multi-stage fuzzy inference, the prosthesis can determine the stiffness of the object and hold an object without injuring it, meanwhile, the hysteresis phenomenon is an 80196KC single-chip microcontroller to replace the original controller.

In this paper, we present an exoskeletal haptic device named SKK Hand Master. This device is directly driven linkages actuated with small ultrasonic motors. By adopting ultrasonic motors that have advantageous features useful for cybernetic actuators, a compact haptic device containing whole driving packages can be established without additional power transmissions such as tendons. Methods for measuring joint postures and joint torques are developed and a new control strategy called PWM/PS is proposed to overcome intrinsic disadvantages such as hysteresis. Issues regarding design and construction of the device are addressed and several results of experiments for the evaluations of performance are included.

The improvement of high-tech is closely linked with the improvement of the man himself, technogenesis affects anthropogenesis, and human development signifies transhumanism. Informatization and virtualization, digitalization and computerization cover more and more areas of human activity one can record and state the actualization and accentuation of what is happening online and it kind of sacralization, alibization and deification. The anthropological potential of IT also increases and expands accordingly. With the help of technology, scientists hope to establish communication with animals, study their language and intelligence, use elements of AI, to promote the protection of the rights of robots and cybernetic organisms.

불연속면의 기하학적 특성 조사는 일반적으로 조사자가 암반 노출면에서 직접 측정 작업을 수행하여 자료를 획득한다. 이러한 방법은 조사 범위에 대한 제약이 있을 수 있고, 자료의 획득과 처리에 많은 비용과 시간을 소요하게 되는 단점이 있다. 이를 극복하기 위하여 디지털 영상 분석은 현장 측정에 대한 대안적인 방법으로 제시될 수 있으며, 자동화된 측정과 분석을 제공한다는 장점이 있다. 본 연구는 디지털 사진기에 의해 촬영된 암반 노출면 영상으로부터 절리의 궤적을 인식하기 위한 목적으로 수행되었으며. 결과적으로 부존하는 절리맵을 자동화된 방법으로 작성하고자 하였다. 이를 위하여 개발된 해석 과정은 Media cybernetic사의 ImagePro Plus ver 4.1의 매크로 명령을 사용하여 프로그램으로 작성하였다. 본 연구에서 수행된 영상처리 과정은 영상처리, 절리 인식, 절리 궤적 추적 단계로 구분된다. 영상 처리 단계는 암반 사면 영상에 나타나는 노이즈를 제거하거나 완화시키기 위한 단계로서 영상 필터들을 조합하여 적용하였다. 절리 인식단계는 암반과 절리의 명도차에 의한 국부적인 절리 궤적을 인식하는 과정이다, 인식된 절리는 절리 궤적 추적 단계에서 수치적 의사 결정이 가능한 구조로 재구성된 후 서로 연결되어 절리맵으로 완성된다. 암반 사면의 원 영상과 이러한 영상 처리 알고리즘에 의한 일련의 과정을 거쳐 작성된 절리맵을 비교한 결과, 75～80% 정도의 불연속면들이 인식된 것으로 나타났다. 본 연구와 관련하여 앞으로는 절리 궤적 추적에 더욱 적합한 영상을 획득하기 위한 영상 필터의 조합부분과 절리 궤적의 연결과정에서 seed pixel을 자동적으로 선택할 수 있는 부분을 보다 집중적으로 연구할 필요가 있을 것으로 생각한다.

The 1960s in Britain was the period of rapid economic and social change. Under this circumstance, the visionary architect Cedric Price designed the Fun Palace, of which idea came from the theatre producer, Joan Littlewood. They hoped this place to be an improvisational learning space, so Price proposed the building as 'kit of parts' which can respond to programmatic indeterminacy. Cybernetics was introduced to control this flexibility dramatically changed the character of the project from 'theatre of people' to 'interactive machine'. That resulted in the change of the status of user from subjective human beings to abstract data in the cybernetic algorithm as well, and led the project to a completely opposite direction from that Price intended. After Fun Palace, cybernetics technology could still be found in his other projects, and it can be assumed that this was because the algorithmic system of cybernetics were on the same line of thought of Price's idea - anti-building or 'kit of parts'. The effects of cybernetics varied in projects; Similar negative effect in Fun Palace can be found in Generator project, but on the other hand, in Potteries Thinkbelt project, cybernetics showed a positive aspect by contribution to the development of project on the formal analogy of algorithmic network.

The objective of this study was to develop a model for simulating gastric digestion in the pig. The model was constructed to include the chemical and physical changes associated with gastric digestion such as enzyme release, digestion product removal and gastric emptying. Digesta was collected from the stomach cannula of pigs to establish system parameters and to document the ability of the model to simulate gastric digestion. The results showed that the average pH of gastric digesta increased significantly from 2.47 to 4.97 after feed consumption and then decreased 140 min postprandial. The model described the decrease in pH within the pigs' stomach as $pH_t=5.182e^{-0.0014t}$, where t represents the postprandial time in minutes. The cumulative distribution function of liquid digesta was $V_t=64.509e^{0.0109t}$. The average pepsin activity in the liquid digesta was 317Anson units/mL. There was significant gastric emptying 220 min after feed consumption. The cybernetic dynamic system of gastric digestion was set according to the above data in order to compare with in vivo changes. The time course of crude protein digestion predicted by the model was highly correlated with observed in vivo digestion (r = 0.97; p = 0.0001), Model prediction for protein digestion was higher than that observed for a traditional static in vitro method (r = 0.89; p = 0.0001).
