본 논문에서는 디지털 제어부를 공유하며, 회로 동작시간의 분배 방식을 통해 다중 출력을 지원하는 SMPS를 제안한다. 제안된 회로는 Pseudo Relaxation Oscillating 기법의 DPWM 발생기를 사용한다. 제안된 SMPS는 회로의 동작시간 분배 방식을 사용하여 기존의 DPWM 발생기에서 문제가 되는 큰 면적의 디지털 로직 컨트롤러를 공유하는 형태이기 때문에 칩 면적과 효율 측면에서 큰 이점을 가지지만, 각 DPWM 발생기의 실시간 제어가 어려우며 불안정한 출력 전압을 공급할 수 있다는 단점을 가진다. 이를 해결하기 위해 본 논문에서는 동작시간 분배 방식으로 인해 동작클록이 인가되지 않은 DPWM 발생기들의 출력전압을 실시간으로 피드백 받아 안정된 출력 전압을 공급할 수 있는 실시간 전류 보정 기법을 제안한다. 제안된 SMPS를 100MHz의 내부 제어 동작 주파수와 10MHz 스위칭 주파수로 동작시킬 시, 소모되는 내부 코어 회로의 최대 전류는 4.9mA이며, 출력 버퍼를 포함한 전체 시스템의 전력 소모는 30mA이다. 또한 800mA, 100KHz의 load current regulation 조건으로 시뮬레이션 시, 3.3V 출력전압에 대한 최대 리플 전압은 11mV, Over/Undershoot voltage는 각각 10mV, 19.6mV 이다. 코어 회로의 크기는 $700{\mu}m{\times}800{\mu}m$의 작은 면적으로 구현가능하다. 제안된 회로는 Dong-bu Hitek BCD $0.35{\mu}m$ 공정을 이용한 시뮬레이션을 통해 검증되었다. This paper suggests a multi-level and multi-output SMPS based on a shared digital logic controller through independently operating in each dedicated time periods. Although the shared architecture can be devised with small area and high efficiency, it has critical drawbacks that real-time control of each DPWM generators are impossible and its output voltage can be unstable. To solve these problems, a real-time current compensation scheme is proposed as a solution. A current consumption of the core block and entire block with four driver buffers was simulated about 4.9mA and 30mA at 10MHz switching frequency and 100MHz core operating frequency. Output voltage ripple was 11 mV at 3.3V output voltage. Over/undershoot voltage was 10mV/19.6mV at 3.3V output voltage. The noise performance was simulated at 800mA and 100KHz load regulation. Core circuit can be implemented small size in $700{\mu}m{\times}800{\mu}m$ area. For the verification of proposed circuit, the simulations were carried out with Dong-bu Hitek BCD $0.35{\mu}m$ technology.

Wider society is still inclined to consider technology as `applied science` In this view, technology is subsumed by science. `Technology itself` isn`t count as theme of philosophical thinking. The notion of technology as `applied science` may be summed up the historical and ontological priority of science over technology. The former is related to both the forgotten history of technology and to the specific philosophical traditions of platonism and idealism. By the way, this usual idea for technology is deep-rooted in the modern conception of technology. The modern conception of technology is composed of theses, `technology as extension of power`, `non-independence in the value and mechanism of technology`, `technology as applied science`. Thus treating technology as the object of philosophical study is dissolving the modern conception of technology and requiring alteration of philosophy itself. That is, this is grounding the philosophy of technology not in platonism and idealism, but instead, in the praxis-perceptive materialism. This dissertation dissolve the modern conception of technology by reinterpreting Heidegger`s existentialist phenomenology and Don Idhe`s philosophy of technology. Further, this dissertation, in introduction problems that Ihde`s phenomenological deconstruction retain, propose philosophical investigation direction of technology.

북의 국가담론: 봉건적 가부장에서 젠더화된 민족국가로

Discourse has a materiality in that it based on objective relationships and identification with them, physical apparatuses such as schools and churches, and produces subjects that perform specific actions. Thus, it can be said that the study on the North’s state discourse is a study on the three points. The strength of the system decreases as the degree of repression increases, and increases as the spontaneity increases. However, previous studies have been focused on compulsory or brainwashing by the state apparatus and ideological ruling function of Chuche Ideology. Thus, this paper is not a study on the ideological state apparatus such as schools, Party-People’s Committee, etc. that produce the North’s state discourse, but focuses on the social relationships on which the North’s state discourse is objectively based and the mechanism that imaginatively identifies with it. This paper examines the fact that the North’s state discourse is not a feudal patriarchal and Confucian ideology, but a discourse in which the state is gendered through the analysis of ① theory of the large socialist family and ② theory of social-political life. Also, based on this analysis, it deals with historical experiences, cultural assets, and objective life conditions as resources for imaginative identification in which ③ the gendered national discourse can operate. North’s gendered state discourse is not Confucianism, but on the soil of ‘nation’, it created a symbolic system that loyal to the leader as a political father with the trauma of colonization and division as the core, appropriating the historical assets of the anti-Japanese armed struggle, and making the states as a family. Therefore, this article assert that the study of the North’s gendered national discourse not only studies on the dissolution and cracking of these materiality but also the resolution of structural-cultural violence, the women’s-sexual liberation Including body’s liberation.

분단의 아비투스에 관한 철학적 성찰

박영균 ( Young Kyun Park ) 한국철학사상연구회 2010 시대와 철학 Vol.21 No.3

This paper is being made to clarify how is `hostile symbiosis` of South/North embodied in bodies, embedded in life-form and repeatedly reproduced in the structure. The north and south is `others` with each other. And the otherness of others hinders understanding and communication between each other. Therefore, this paper suggest the need a term, `habitus of division` in order to understand the otherness of others, and are dealing with the following four topics. First, the `habitus of division` is not only a opposition between the system of South and North but also a structure embodied in lives of South and North as a structured and structuring structure. In this regard, the paper would be defined the concept of habitus used by Bourdieu in virtue to compare Foucault with Freudian and illustrated this positive and negative aspects to clarify the mechanism that the division operate in the daily. Second, the paper tried to define a special nation-state caused by the division of peninsula as a defect nation or spilt nation of nation≠states and treat a special nation-state of North and South as a modern nation-state working to bridge this gap. Therefore, this paper was trying to deal with the national libido and it`s frustrating, the formative process of the division habitus in the competitive of legitimacy between the system of South and North by borrowing from Freudian`s notion, Third, this paper tend to get at the root of the process of internalization that the habitus of division based on the adversarial structure of division embodied in the our bodies by doing investigate the body-discipline and symbolic power, type of illusions restored after South/North division and stemmed from Japanese colonial rule. It`s the process of production to reproduce a dichotomy between purity-good and pollution-evil, make people subjects in the spilt nation. So finally, this paper proposes the following: 1. To thinking the division and reunification of peninsula through `Participatory objectification`, 2. To doing communicate and play a game by accepting the structure of misunderstand-illusions in interaction between the two sides, 3. A strategy of unification that the social body of division will eventually metamorphose into the social body of unification by changing the habitus of division based on the adversarial structure of North and South into the habitus of brotherhood based on the communication and solidarity.

분단 트라우마의 사회적 치유 모델 연구: DMZ의 치유와 공간의 생산

박영균 ( Park¸ Young-kyun ) 한국철학사상연구회 2021 시대와 철학 Vol.32 No.3

This article analyzes how a divided nation uses the DMZ to produce the DMA syndrome, which is the cultural background of division violence. Thus, this article proposes a spatial practice of healing the DMZ, which has become a space of division-Cold War due to divisional violence, and transforms it into a space of de-division while restoring it to the original peace space. However, this is only the starting point for healing DMZ, not the destination. Healing is to activate one's own vitality blocked by the traumatic disorder so that the libido flows. Thus, this article proposes a strategy of empathizing with the wounds of division and war, maintaining distance, and working through based on the restoration of the locality of the DMZ border area. In short, from the perspective of healing the DMZ, this article argue that a production of DMZ should be the agent who produces the subject of ethical-political action that creates peace and unification by sensibly-experientially creating genuine mourning on the existential equality of death as breaking away from the dichotomy of enemy and self.

네트워크 디지털 사이니지의 콘텐츠 다운로드 및 연속재생을 위한 최소 초기 지연시간 결정

박영균(Young Kyun Park),남영진(Young Jin Nam),권영직(Young Jik Kwon) 한국산업정보학회 2012 한국산업정보학회논문지 Vol.17 No.2

디지털 사이니지란 멀티미디어 기반의 정보와 광고를 소비자에게 전달하는 스마트 전자 디스플레이 시스템을 일컫는다. 대부분의 디지털 사이니지는 일련의 멀티미디어 콘텐츠를 원격 네트워크 스토리지로부터 로컬 디스크로 다운로드 한 후에 재생을 시작한다. 하지만 모든 콘텐츠를 다운로드 한 후 재생할 경우에 긴 초기 지연시간을 초래한다. 본 논문에서는 디지털 사이니지에서 이러한 초기 지연시간 문제를 정의하고, 주어진 네트워크 대역폭 및 멀티미디어 콘텐츠의 품질과 크기에 따라서 최소한으로 필요한 초기 지연시간을 계산하는 방법을 제시한다. 또한, 디지털 사이니지 상의 다양한 멀티미디어 콘텐츠들을 이용하여 본 제안 기법의 성능을 분석한다. Digital signage is referred to as a smart electronic display system that delivers multimedia-based information and advertisements to customers. Typically, the digital signage starts its playback after downloading a list of multimedia contents from network storage to its local disk. However, a way of downloading the entire contents before its playback entails a long initial delay time. In this paper, we formulate a problem of the initial delay time and provide a solution to compute a minimally demanded initial delay time according to a given network bandwidth and qualities/sizes of the multimedia contents. In addition, we analyze the performance of the proposed solution with various multimedia contents on digital signage.

민주주의 이후의 민주화론에 대한 맑스주의적 비판

박영균 ( Young Kyun Park ) 고려대학교 민족문화연구원 2012 민족문화연구 Vol.56 No.-

This paper aims to a Marxist criticism about Choi``s theory of democratization in the development of democracy. In this regard, this is dealing with the relationship between the party democracy and crisis of party politics in Korea, and secondly, the issues of a essential power to innovate political parties. Thirdly, this is dealing with the limitation of representative system in neo-liberalism and finally, the relationship between ideal and reality of democracy. Through such discussions, this paper has been criticized the theory of democratization in the development of democracy. First, it is considered the crisis of representative system and party democracy only as a peculiarity in Korea. Second, It is without looking at the limitation of representative system and party democracy in neo-liberalism. Third, it is causing the results to eliminate the self-governing principle of democracy by seized with the reality. Therefore, this paper argues that Choi``s theory of democratization in the development of democracy should be extended to more ideologically. Furthermore, this argues that it firstly, seek for a subject formation based on the activation of movement politics, secondly, will move toward the ideals of democracy as a self-governing beyond a representative system, and thirdly, should be accept the key issues of commune.
