The Application of Logic Based Computerized Evaluation in Determining Procedure Flow in APR1400 CPS

No Kyu Seong,Yeong Cheol Shin 대한인간공학회 2012 대한인간공학회 학술대회논문집 Vol.2012 No.5

Objective: This paper introduces the logic based computerized evaluation in determining procedure flow in Advance Power Reactor 1400 (APR1400) computerized procedure system (CPS) and suggests guidelines to increase operator performance from Human Factors Engineering (HFE) point of view. Background: Plant procedures are instructions to guide operators in monitoring, decision making, and controlling nuclear power plants (NPPs). While plant procedures historically have been paper-based, computer-based procedures are being developed to overcome the drawbacks of paper based procedures. The CPS is used to integrate the operational instructions, plan process information and computerized operator support functions in advanced main control room (MCR) of APR1400. The logic based computerized evaluation of CPS functions can help MCR operators to determine procedure flow with higher speed and accuracy. The guidelines for this logic based computerized evaluation are important for procedure writers to select the right type of operator interaction depending upon the operational situation such as urgency of the operator actions. Method: The logic based computerized evaluation types in CPS are Auto evaluation type and ManualAuto evaluation type. Auto evaluation type displays the evaluation value for the instruction and ManualAuto evaluation type displays evaluation value for the instruction after the operator inputs evaluation value. This logic based computerized evaluation types are applied to computerized procedures in NPPs. Conclusion: This paper describes Auto/ManualAuto evaluation types in CPS and suggests guidelines to increase operator performance from HFE point of view and plant operation procedures. The developed Shin-Kori NPPs 3&4 units computerized procedures for considering suggested guidelines will be verified & validated at the Shin-Kori 3&4 final (HFE) V&V.

이 연구는 전남 신안군 상태도에 위치한 상서고분군 축조에 사용된 석재들에 대한 암석학적 특성과 채석 등 유통과정에 대해 고찰하고자 하였다. 고분 축조에 사용된 석재들에 대한 암석학적 특성 연구는 외관적 관찰에 의한 암석기재적 연구와 편광현미경 하에서 암석의 광물조성과 조직특성에 대한 연구 및 암석의 주성분 함량조성을 통한 지구화학적 연구를 수행하였다. 이 연구들과 함께 주변지질들과 관련하여 고분석재들의 채석과 이송 등에 대한 연구도 병행하였다. 고대로부터 신안군 일대는 한국-중국-일본을 연결하는 고대 해상교통로에 중요한 위치를 점하는 것으로 알려져 고분 축조에 사용되었던 석재 연구는 고대 해양사 측면에서 의미를 지닌다고 할 수 있다. 기재적 관찰에서 석재들은 중성암맥 기원인 안산반암을 제외하고는 대부분이 응회암류에 해당한다. 이들은 라필리응회암과 세립질 응회암으로 구분되는데 대부분 세립질 응회암에 속한다. 응회암 구성입자들은 각상에서 초각상이고 분급도는 불량하다. 세립질 응회암들은 매우 치밀한 조직을 보유하고 특히 라필리응회암의 불규칙한 이탈흔들은 타포니(tafoni)와 관련될 가능성이 있다. 응회암의 입자들은 사장석편과 암편 등이 주를 이루며 크기 범위가 광범위하다. 사장석들은 알바이트 쌍정이 잘 나타나고 격자쌍정을 이루는 미사장석들도 출현한다. 응회암의 치밀한 조직은 부분적으로 속성작용과 관련되는 것으로 여겨지며 다양한 풍화정도를 보인다. 또한, 미세한 석영맥들이 응회암들을 종횡으로 관통하고 있다. 상기한 상서고분군 석재들에 대한 주성분 원소 함량에 대한 지구화학적 연구에 의하면, 이들 응회암은 화산암류 관점에서 산성암계열에 근접한 중성암 계열 및 산성암계열에 해당시킬 수 있다. 이러한 함량분포 특성 상, 이 응회암들은 두 가지 군으로 나눌 수 있다. 그리고 TAS(total alakali vs silica) 분류에서 이 응회암들은 저알칼리암 계열에 도시된다. 고분축조에 사용된 응회암들은 주변의 암석과 매우 유사하며 석재들 자체도 광물조상과 조직특성에서 서로 유사정도가 높다. 일반적으로 응회암들은 판상특성, 가공의 용이성 및 상대적인 견고성으로 고분과 건축 등에 많이 이용되어 왔다. 이러한 결과들을 기반으로 고분축조에 사용된 응회암들은 산성암계열에 근접한 중성암계열 및 산성암계열 기원을 가지며 주변 암석에서 채석·이송된 것으로 추정된다. This study considers on petrological characteristics and distribution to building stones of Sangseo tumuli in Santae Island, Shin-an, Jeonnam. The petrological study on the stones includes visually petrographical descriptions, textural study by polarized microscope and geochemical analysis. Along with the study, distribution routes of the stones were traced based on the regional geology of the island. Since ancient times, the study area is important as a base on international maritime traffic route. Therefore, studies on the tumuli are meaningful for ancient maritime history. In visual observation, above building stones are of tuffs except for an andesitic porphyry considered as intermediate dyke. The tuffs are assigned to lapilli and fine ones. Their grains are poorly sorted and angular to very angular in roundness. In particular, the fine tuffs show very dense textures and take up the most part of the building stones. In addition, the stones have irregularly removed depressions inferred as the linkage to tafoni, in lapilli tuffs particularly. The tuffs are mainly of plagioclases laths, rock fragments and matrices and ranges widely in grain size. The plagioclases show mostly unambiguous albite twin. And, microcline crystals are observed in the tuffs too. Matrices in the tuffs are considerably dense and weathered. Dense texture in the rocks are related to diagenesis in part. In addition, thin quartz veins irregularly intruded the rocks vertically and horizontally. According to the geochemical analysis of building stones of above tumuli, the stones might be intermediate rock series near acidic rock ones and acidic rock ones in the correspondence of volcanics. Therefore, the tuffs probably grouped as two types and are assigned to subalkaline rock series by TAS diagram. Most the building stones mutually resemble in visual and textural characteristics. Tuffs are generally platy, easy in use and relatively hard. In addition, rocks very similar to the building stones are widely distributed in surrounding area. Synthesizing above results, it is considered that tuffs used in tumuli building are corresponded to intermediate rock series near acidic rock ones and acidic rock, and got from surrounding rocks.

Objectives: This study aims to examine if a garbage dumping site has real and negative influence on the quality of life (QOL) for the nearby residents. The net effects of the residential distance from the garbage dumping site and from the garbage truck route were investigated for five domains of the QOL. Methods: Two hundred fifty seven Shin-dong Myeon residents, Chun-cheon Si, participated in a self-administrated survey. The Shin-dong Myeon garbage dumping site began operating in 1996. ANCOV A with generalized linear models and multiple regression analysis were performed. Results: Descriptive analyses show that a residence nearby a garbage dumping site is negatively associated with the physical and environmental domains of the QOL. The residential distance from the garbage truck route does not exert any significant effect on various domains of QOL, except for the environmental domain. On the multivariate analysis, the residents living near the garbage dumping site tended to have a significantly negative QOL in the physical and environmental domains. However, the distance from the garbage truck route did not show a significant nor substantial effect on the QOL. The demographic and socioeconomic control variables are associated with a number of the QOL domains, and their patterns are consistent with the general expectations. Conclusions: The results indicated that a garbage dumping site is considered to be an environmental hazard among the nearby residents according to the lower scores on the physical and environmental domains of the QOL. The findings from this study provide comprehensive understanding on the residents' QOL, and they may help politicians and policy makers make decisions for appropriate interventions.

선물거래등의 회계처리방법에 관한 연구

신영식 大邱大學校 社會科學硏究所 1997 社會科學硏究 Vol.4 No.1

오늘날과 같은 경제체제하에서 각 기업은 국제간의 거래에 따르는 제반 위험 즉 상품의 가격, 주식 및 채권 등의 가격, 이자율이나 환율 등의 변동에 따르는 위험에 직면하게 된다. 이러한 위험관리 수단으로 제기되는 여러가지 기법중 선물거레등이 출현함에 따라 미국을 비룻한 선진제국은 물론 우리나라에서도 선물거래등의 회계처리방법에 관한 연구가 활발히 이루어지고 있다. 미국에서는1975년에 발표한 FASB. No.8에 이어서 1981년에 FASB. No.52를 발표하고1984년에는FASB. NO.80을 발표하기에 이르렀다. 우리나라는 1990년 기업회계기준이 개정되기 이전에는 기업회계기준에 선물거래등의 회계처리 방법에 관한 아무런 규정이 없이 단지 1988년에 제정한 "기업회계기준에 관한 예규"에 의하여 회계처리를 하여 왔다. 그러나 1990년 기업회계기준을 개정하면서 기업회계기준에 "선물환거래등의 처리' 라는 규정을 신설하고 이어서 1992년에 새로운 예규를 발표하면서 종전의 예규를 폐기 하였다. 1996년 다시 기업회계기준을 개정하면서 "선물거래등의 처리"라는 규정을 두면서 파생상품등에 대한 회계처리방법의 근거를 마련하였고 이어서 기업회계기준에 관한 예규의 개정안을 마련하기에 이르렀다 그러나 현행 규정에는 다양한 파생상품에 관한 상세한 회계처리규정을 마련하지 못하는 등 다음과 같은 문제점을 가지고 있다. 첫째: 선도거래와 선물거래를 구분하는 명백한 기준이 없다. 둘째: 파생상품(delivative instruments)등에 관한 회계처리 규정이 미비되어 있다. 셋째: 위험회피목적과 투기목적의 구분이 명백하지 않다. 현행 우리나라 선물거래등의 회계처리방법에는 이상과 같은 문제점을 안고 있기 때문에 이 분야에 관한 연구가 보다 활발히 이루어져 이러한 문제점을 해결하여야 할 것으로 생각된다.
