Total suspended particles(T.S.P.), coarse and find particles, were collected on the quartz fiber filter using Andersen Hi-volume air sampler from March 1985 to February 1986 at Chung Ang University. Six heavy metals(Fe, Zn, Pb, Cu, Mn, Cd) in the particle were analyzed by atomic absorption spectrophotometry. The mean value of T.S.P. was 113.21 ㎍ / ㎥. The mean values of 6 heavy metals (Fe, Zn, Pb, Cu, Mn, Cd) were 2439.58, 1306.85, 571.02, 125.46, 66.41, 3.30 ng / ㎥, respectively. The concentration of T.S.P. and heavy metals shows higher value in Winter-Spring time (Dec.∼May) than in Summer-Autumn time (Jun.∼Nov.) Statistical analysis showed that there was a correlation between T.S.P. and Cu, Mn, Fe in cosare particles, and between T.S.P. and Cd, Pb, Cu, Mn in fine particles.

개인 투자자의 회계정보에 대한 지불의사금액 추정: 조건부가치측정법(CVM) 적용

권상호,유상열 한국회계정보학회 2013 회계정보연구 Vol.31 No.1

Accounting information has characteristics of public goods, so we tried to assess individual investors' willingness to pay (WTP) for accounting information by a contingent valuation method (CVM) that is generally used for estimating the value of public goods. Additionally, we tried to estimate the incremental WTP of Korean International Financial Reporting Standards (K-IFRS) which had been adopted in Korean listed companies since 2011. In order to achieve the purposes of this study, the survey of adults more than 20 years old was conducted. Respondents were divided into two groups; the investment-experienced group and investment-inexperienced group, and we estimated per capita WTP of each group. The WTP of the investment-experienced group can be thought as a use value, whereas the WTP of the other group can be regarded as a non-use value. A double-bounded dichotomous choice was used as a method inducing per capita WTP of each group, and logit model was used for a statistical analysis. Per capita WTP of each group was estimated with median. As a result of this study, the annual per capita WTP of the investment-experienced group was about 6,539 Korean won, and that of the other group was about 5,816 Korean won. In addition, we analyzed how much the WTP was affected by K-IFRS. The incremental WTP of the investment-experienced group was almost zero, and that of the other group was 176 Korean won. One of the reasons that the incremental WTP of K-IFRS was very small was thought that many respondents lacked practical understanding and experience because K-IFRS has been applied since 2011. The main contribution of this study is that we estimated WTPs for accounting information using CVM, not relying on capital markets. The WTP in this paper can be used as a basis of evaluating social benefits of accounting information and analyzing economic feasibility of producing the information. 본 연구는 회계정보가 공공재적인 성격을 갖는다는 점에 착안하여 공공재의 가치 평가방법인 조건부가치측정법(CVM)을 이용하여 개인투자자의 회계정보에 대한 지불의사금액을 평가하였다. 2011년부터 국내 상장법인에 적용되고 있는 한국채택 국제회계기준(K-IFRS)에 의한 회계정보의 증분 지불의사금액도 추정하였다. 이를 위해 서울에서 거주하는 20세 이상의 성인을 대상으로 설문조사를 실시하였으며, 응답자를 투자경험자와 투자미경험자로 구분하여 각각의 1인당 지불의사금액(WTP)을 추정하였다. 공공재의 가치는 사용가치와 비사용가치로 구분되는데, 투자경험자의 WTP는 사용가치를, 투자미경험자의 WTP는 비사용가치를 나타낸다. 분석방법은 로짓모형(logit model)을 이용하였고, WTP는 지불의사금액의 중앙값(median)으로 추정하였다. 연구결과 투자경험자의 1인당 WTP는 연간 6,539원이고, 투자미경험자의 1인당 WTP는 연간 5,816원으로 평가되었다. K-IFRS 도입에 따른 회계정보의 증분가치를 추정한 결과, 투자경험자의 1인당 WTP 증분가치는 거의 없었으나, 투자미경험자의 1인당 WTP 증분가치는 연간 176원으로 평가되었다. 이는 2011년부터 국내 상장기업에 K-IFRS가 적용된 점을 감안할 때 K-IFRS에 대한 이해와 경험이 아직은 부족했기 때문으로 보인다. 본 연구의 공헌점은 회계정보의 유용성을 평가하는 데 공공재의 가치 평가방법인 CVM이 적용될 수 있음을 보이고, 개인투자자들로부터 구체적인 WTP 금액을 추정하였다는 것이다. 이러한 연구결과는 회계정보의 사회적 편익을 산출하고 정보생산의 경제성을 판단하는 데 유용한 지침이 될 수 있다. 또한 회계학 분야에서 CVM을 적용하는 다양한 후속연구를 촉발할 수 있을 것으로 기대한다.

선행순서결정문제를 위한 Out-of-Kilter 해법의 적용과부분순환로의 제거

권상호 한국경영과학회 2007 韓國經營科學會誌 Vol.32 No.3

This paper presents two elimination methods of subtours, which is obtained by applying the Out-of-Kilter algorithm to the sequential ordering problem (SOP) to produce a feasible solution for the SOP. Since the SOP is a kind of asymmetric traveling salesman problem (ATSP) with precedence constraints, we can apply the Out-of-Kilter algorithm to the SOP by relaxing the precedence constraints. Instead of patching subtours, both of two elimination methods construct a feasible solution of the SOP by using arcs constructing the subtours, and they improve solution by running 3-opt and 4-opt at each iteration. We also use a perturbation method, cost relaxation to explore a global solution. Six cases from two elimination methods are presented and their experimental results are compared to each other. The proposed algorithm found 32 best known solutions out of the 34 instances from the TSPLIB in a reasonable time

권상호,조경열,김소연,김미정 대구효성가톨릭대학교 식품과학연구소 1993 식품과학지 Vol.5 No.-

식생활에서 대추의 이용성확대 방안을 살펴볼 목적으로 대추와 관련한 그간의 문헌들을 정리해 보았다. 그 결과 대추는 한방에서도 사용빈도가 가장높은 약재이면서 식품으로서도 가치성이 매우 커서 일상의 식생활에서 주식과 함께 이용함으로서 한방식생활의 보편화를 기하는데 가장 편리한 식품으로 평가되었다. 그러므로 대추를 식생활에 쉽게 이용할 수 있는 다양한 가공품의 개발과 응용방법의 확대방안 모색이 요망되었다. The review was summarized to investigate extensive possibilities of jujube fruit for the application of dietary life. Seventy seven referances were organized and discussed in this paper. Jujuba fruits have been used as the famous herb medicine and food materials in Korea, China, and Japan because they contain many kinds of nutrients and components which have a tonic action, urination action, and strength of physical recovery etc. In addition, it was estimated as the most desirable food materials for the dietary life together with the staple foods. Therefore, many studies for processing and application of jujuba fruits on the dietary life were required.

권상호,유상열,황준성 한국상업교육학회 2014 상업교육연구 Vol.28 No.3

본 연구는 개인투자자들의 회계교육수준이 주식시장에서 회계정보의 이용도에 미치는 영향을 조 사하기 위해 수행되었다. 실증분석을 위한 자료는 서울 및 수도권 거주 성인을 대상으로 실시한 설 문조사를 통해 수집하였다. 주요 연구결과를 요약하면 다음과 같다. 회계교육수준과 회계정보이용도의 관계를 검정하기 위해 회귀분석을 실시한 결과, 회계교육수준 은 회계정보이용도에 유의한 양(+)의 영향을 미치는 것으로 나타났다. 추가적으로, 회계교육수준을 구성하는 개별 설문항목들이 회계정보 이용도에 미치는 영향을 분석하였다. 회계교육수준의 측정변 수 중 회계정보에 대한 이해능력과 국제회계기준(K-IFRS)과 기존 회계기준의 차이에 대한 이해도 가 정보이용도에 유의한 양(+)의 영향을 미치는 것으로 추정되었다. 본 연구는 개인투자자들의 회계 교육수준이 회계정보 이용도에 미치는 영향을 분석함으로써 회계정보의 유용성을 실증적으로 검정 하고, 회계교육 개선을 위한 시사점을 제공하였다는 데 공헌점이 있다. The purpose of this study is to examine the effect of individual investors' accounting education (AE) on the utilization of accounting information (UA). Data were collected by questionnaire survey on the individual investors over 20 years old in Seoul area. The AE is measured by 4 factors: the number of accounting subjects they have taken, the ability of understanding accounting information, whether they know about the adoption of Korean international financial reporting standards (K-IFRS) or not, and the understanding of differences between K-IFRS and the past accounting standards. The results are as follows: First, the AE was positively correlated with the UA. Especially, the ability of understand accounting information had the highest correlation with the UA. This implies that we need to improve the understandability to enhance the UA. Third, the AE had significant effect on the UA controlling the perceived reliability of accounting information, individuals' investment amounts and demographic characteristics such as sex, educational backgrounds and income level. Additionally, we conducted an analysis to explore the effect on the UA using more detailed variables. As a result, the ability of understand accounting information and the knowledge of differences between K-IFRS and the past accounting standards had significant impact on the UA. The results gleaned from this study may contribute to investigate the relationship between AE and UA, and therefore to propose desirable ways of improving the usefulness of accounting information.

비대칭 외판원문제에서 Out-of-Kilter 호를 이용한 Perturbation

권상호 한국경영과학회 2005 韓國經營科學會誌 Vol.30 No.2

This paper presents a new perturbation technique for developing efficient iterated local search procedures for the asymmetric traveling salesman problem(ATSP). This perturbation technique uses global information on ATSP instances to speed-up computation and to improve the quality of the tours found by heuristic method. The main idea is to escape from a local optima by introducing perturbations on the out-of-kilter arcs in the problem instance. For a local search heuristic, we use the Kwon which finds optimum or near-optimum solutions by applying the out-of-kilter algorithm to the ATSP. The performance of our algorithm has been tested and compared with known method perturbing on randomly chosen arcs. A number of experiments has been executed both on the well-known TSPLIB instances for which the optimal tour length is known, and on randomly generated instances. For 27 TSPLIB instances, the presented algorithm has found optimal tours on all instances. And it has effectively found tours near AP lower bound on randomly generated instances.

권상호,조경열 대구효성가톨릭대학교 식품과학연구소 1993 식품과학지 Vol.5 No.-

대추의 품질평가를 위한 하나의 방법으로 수확시기와 건조방법별에 따른 c-AMP이 함량을 조사하였다. 또 중국산 대추와 함량을 비교하였다. 그 결과 한국산 대추는 중국산 대추에 비하여 함량이 12-59%범위로 높았으며 반착색단계(HF: half riped stage)에서와 완전착색단계(CS: completely riped stage)에 함량이 높았고 연화가 시작됨과 함께 함량이 감소되었다. 또 건조방법별 c-AMP의 함량은 동결건조>blanching 후 자연건조>열풍건조>자연건조 순으로 blanching을 하지 않고 자연건조시킨 대추에서 함량이 가장 낮았다. Cyclic AMP(c-AMP) content was analyzed by HPLC for the purpose of quality evaluation of the dried Zizyphus jujuba fruit on the different maturity and various drying methods. And also, c-AMP content of the dried fruit from Korea was compared with that from China. c-AMP content of the fruit from Korea was higher within the limits of 12-59% than that from China. The c-AMP content was high in the half riped stage and completely riped stage and then, it decreased in the softening stage. The content of c-AMP in the dried fruit was high in order of freeze drying, natural drying after treatment of blenching, hot air drying, natural drying.
