전기자동차의 효율을 증대하기 위하여 많은 방법이 시도되었다. 시도한 중요관심사 중 하나가 난방시스템의 효율 증대이다. 그럼에도 불구하고 많은 효과를 보여주지 못하였다. 일반적으로 기존 차량에서의 난방시스템은 크게 중요하지 않았다. 차량의 엔진에서의 발열을 이용하였기 때문이다. 본 연구에서는 일반적인 PTC 시스템을 제어 방법을 지능제어 방법을 통하여 높은 에너지 효율을 얻었다. In order to improve efficient quality of EV, lot of methods has been tried. One of the main concerns in attempting is to increase the Heating system. Nevertheless not much improvement has been achieved. Generally the heating system in vehicle is not important. Because of vehicle heating system is used to engine temp. Remarkable energy efficient of development system from conventional PTC is demonstrated both in simulation and experiment as well.

PZT(80/0) powder was prepared by a sol-gel method and PZT thick films were fabricated by the screen-printing method on the alumina substrates. The coating and drying procedure was repeated 4 times. And then the PZT(20/80) precusor solution was spin-coated on the PZT thick films. A concentration of a coating solution was 0.5 mol/L and the number of coating was varied from 0 to 6. The porosity decreased and the grain size increased with increasing the number of coatings. The thickness of the PZT-6(6: number of coatings) films was about 60 ㎛. The relative dielectric constant increased and the dielectric loss decreased with increasing the number of PZT(20/80) sol coatings. The relative dielectric constant and dielectric loss of the PZT-6 thick film were 275 and 3.5%, respectively. The remanent polarization, coercive field and breakdown strength of the PZT-6 film were 19.8 μC/㎠, 13.7 ㎸/㎝ and 130 ㎸/㎝, respectively.

Application of Soft Controls in Nuclear Safety Systems

Park Sang Man(박상만),Lee Kwang Jae(이광재) 한국엔터테인먼트산업학회 2014 한국엔터테인먼트산업학회 학술대회 논문집 Vol.2014 No.5

The use of conventional control devices such as pushbuttons, toggle switches, thumbwheels and rotary controls in a nuclear generating stations requires the allocation of a considerable amount of control panel space as well as the cost of multiple input devices and their associated wiring. Alternatively, computer-based virtual controls can be implemented via the use of a graphical user interface(GUI) on touch screen, video display units(VDUs). Virtual control panels offer significant advantages over discrete controls in these two areas. In addition, as virtual devices, they can be reconfigured to match the real time context of the control task at hand. However, due to the technologies employed and the operational and developmental requirements associated with Class 1E nuclear safety systems, there are several challenges in the development of such a system that must be addressed.

라이어널 트릴링의 『성실과 진정』 다시 읽기

박상만(Sang-Man Park) 신영어영문학회 2009 신영어영문학 Vol.42 No.-

Sincerity and Authenticity is essentially beyond summary, because its value consists largely in detailed nuance and variation. But we need to distinguish between sincerity and authenticity to a point of high focus in order to bring into the glare of the explicit some of the implication we gather from this book. Sincerity is a social virtue, a compact between me, myself, and you; authenticity is an assertion and defiance to cut away the falsities of culture. Sincerity speaks for a conduct of should; authenticity a repudiation of its bad faith. Sincerity implies a recognition of our limits, while authenticity asserts the self as absolute. Sincerity belongs to an attribute of Romanticism, authenticity to training of Modernism. The ground on which Trilling makes his judgement issues from rooted conviction. He wants people to uphold character. He has pursued the intention of sustaining the authenticity of human existence that formerly had been ratified by God. It is his purpose to keep all things and, above all our self from becoming “weightless.”

토마스 하디의 『비운의 주드』에 나타난 사회부적응 문제 고찰

박상만 ( Park Sang-man ) 대한영어영문학회 2008 영어영문학연구 Vol.34 No.2

This thesis aims to investigate the aspects of social inadaptability in Jude the Obscure. This work really develops into a battle between reality and ideal. The hero Jude is confronted with ruin by the struggle between Arabella for physical sexuality and Sue for spiritual one. Jude the Obscure, one of the best works in the Victorian Age, shows the aspects of his gloomy and deterministic viewpoint. In this work, The hero Jude seeking for social success arrives at the downfall in the end due to his burning desires that he tries to get over social problems. However, Jude’s characteristic weakness, strong sexual impetus, and habitual drinking cause the hero to destroy his life. In this work, Hardy indicates the structural contradiction regarding education, marriage, and religion problems in the Victorian age. Hardy deals with inner problems of human beings oppressed by the convention of the time. Jude attempts to live his life according to his own nature, rejecting social convention. In the work, Jude continues to struggle against his life to the end, and finally the hero Jude is destroyed by the social inadaptability. We can feel venerable as we see Jude fight against Fate to the end in spite of his character defects. Therefore, we can reach the conclusion that Hardy’s literature creates the lofty beauty of men’s spirit. (Wonkwang University)

본 연구는 돼지 출하체중 증가가 ``떡지방`` 삼겹살 발생률, 도체 등급 및 도체의 품질 특성에 미치는 영향을 구명하기 의해 수행되었다. 본 목적을 위해 85~150kg 체중 범위의(Yorkshire × Landrace) × Duroc 교잡종 거세돼지와 암퇘지 각각 250두를 도살하여 그 도체를 분석하였다. 거세돼지와 암퇘지의 등지방두께(y;mm)는 각각 다음과 같이 생체중(x;kg)에 선형으로 회귀하였다: y = 0.1827x+3.4825(r²=0.4671) 및 y = 0.2015x-0.6972(r²=0.4736). 삼겹살의 제 11~12 늑골부 5cm 폭의 등쪽 반절편의 지방조직 중량비가 55%를 초과하는 경우를 떡지방의 기준으로 설정했을 때 떡지방 삼겹살은 거세돼지에서 10건 발생하였으나 소매상에서 떡지방 삼겹살로 판정된 경우는 없었다. 과중량으로 인해 도체등급이 강등된 도체는 총 101건(20.2%)에 달하였다. 1+A 등급도체는 다른 모든 등급 도체보다 근내지방도가 높았으나, 근내지방 도와 도체 결함 특성을 제외하면 도체등급간 가시적인 품질 상의 차이는 발견되지 않았다. 결론적으로 도체 품질을 충분히 반영하지 못하고 크기만 클 뿐 정상적인 도체에 대해서는 평가절하는 현행 도체등급 판정기준은 개정되어야 좋을 것이다. 또한 돼지 출하체중을 증가시킬 때 떡지방 삼겹살 발생률은 중요한 고려 사항이 아닌 것으로 사료된다. The present study was undertaken to investigate the effects of increasing pig market weight on the incidence of the ``caky-fatty`` belly, carcass grade and carcass quality traits. To this end, 500(Yorkshire×Landrace)×Duroc market pigs consisting of equal numbers of barrows and gilts were slaughtered at body weights ranging from 85 to 150kg and their carcasses were analyzed. Backfat thickness (BFT; mm) of the barrows and gilts regressed on live weight (kg) linearly as follows: BFT (y)=0.1827x+3.4825(r²=0.4671) and y = 0.2015x-0.6972(r²=0.4736), respectively. The caky-fatty belly, which, by definition of the present study, had=55% fat by weight in the dorsal-side half of a 5 cm-wide belly strip between the 11th and 12th ribs, was found in 10 carcasses from barrows. However, no belly was condemned as ``caky-fatty`` by the retailers. Total number of carcasses which were down-graded on account of overweight was as many as 101 (20.2%). The 1+A-grade carcasses exhibited a superior intramuscular fat score to all other grades, but except for this and the defective quality traits, no visible differences were found in carcass quality among different carcass grades. In conclusion, the current carcass grading system, which is sparingly reflective of the carcass quality and also under-evaluates the larger but otherwise normal carcasses, may as well be revised. Moreover, the incidence of the caky-fatty belly appears not to be a critical factor to be considered when increasing the pig market weight.

박상만(Sang-Man Park),이광재(Kwang-Jae Lee) 한국엔터테인먼트산업학회 2010 한국엔터테인먼트산업학회논문지 Vol.4 No.3

최근 원전의 안전성과 경제성 향상을 위해 신형원자로(APR1400)가 개발되어 왔다. 신형원전은 운전원의 부담과 오류를 감소시키기 위해 첨단형 중앙제어실을 채택하였고 디지털 제어설비를 채택한 계측제어계통을 도입해 설비를 단순화하였다. 종래의 독립적인 핵증기공급계통과 기타 보조설비의 제어계통을 하나의 플랫폼과 네트워크로 통합해 캐비닛 수를 감소시키고 계통의 성능과 정비성을 향상시켰다. 신형 원전의 첨단형 제어실에는 소형 워크스테이션과 대형표시장치를 설치하고 운전원은 좌식으로 모든 발전소의 감시와 제어가 가능하고 워크스테이션이 완전히 상실된 경우에도 운전원은 안전콜솔에서 발전소의 안전정지 상태의 유지가 가능하다. 발전소 운전의 고장 극복 능력 향상을 위해 중요한 안전기능 감시, 성공경로감시 및 비상운전절차서 수행단계 감시와 같은 자동화된 안전감시기능이 제공된다. 또한 이들 첨단형 인간-기계 연계 설계는 분리 및 독립성 요건과 같은 원자력 안전성을 보장하기 위해 요구되는 모든 법규와 표준을 만족하여야한다. 본 논문에서는 신형원전의 인간-기계 설계 개면과 설계특징을 검토하고 컴퓨터기반 소형 워크스테이션 설계에서 핵심적인 현안인 공통모드고장 및 통신의 독립성에 관한 안전성 요건의 충족여부를 분석한다. 신형원전 설비는 종래의 제어실 설비보다 감시, 제어 및 진단업무를 더 양호하게 지원할 것으로 기대되어 차세대 원전에 성공적인 설치가 기대된다. For last 10 years, the standard design of Advanced Power Reactor 1400(APR1400) has been developed to enhance the safety and cost effectiveness of nuclear power plant so that nuclear power can remain more competitive than other energy sources. APR1400 adopts the advanced control room that contributes to the reduction of human errors through minimization of operator"s burden and detection/recovery of operator errors and employed the integrated digital I&C equipment which contribute to the simplification of I&C facility by adopting multi-loop controllers, multiplexing, and DCS. The NSSS/BOP control systems, which have been traditionally independent, are integrated into one DCS platform and one network to reduce the number of cabinets and improve the system performance and maintainability. The APR1400 advanced control room features compact workstations and large display panel. Operator can perform, in a seated position, all plant monitoring and control tasks at any one of the workstations. A safety console is provided in the main control room so that plant safety shutdown condition can be achieved and maintained through the safety console upon total failure of workstations. Automation of safety monitoring functions such as critical safety function monitoring, success path monitoring, and emergency operating procedure step monitoring was implemented to enhance the fault tolerance of plant operation. These advanced MMI design features must be designed while meeting all codes and standards required for ensuring the nuclear safety such as separation and independence requirements. In this paper APR1400 MMI design concept and design features are reviewed and design approaches to meet the some of key issues of a computer-based compact workstation design such as common mode failure and communication independence are analyzed to confirm the conformance to the nuclear safety rules. APR1400 control room features are expected to support monitoring, control and diagnostic tasks better than conventional control room facility will be successfully implemented in next generation nuclear facilities.
