This study analyses the factors that affect the satisfaction of school meals program. To obtain the data, 54 elementary, middle and high schools in Jeonbuk area were chosen for survey. A ordered probit model analysis is conducted to identify the key explanatory variables that affect the satisfaction of school meals about elementary, middle and high school's students. Also, a ordered probit model is used to calculate marginal effects of several key variables. The study finds that key factors that affect to increase the satisfaction of school meals are rural area schools, elementary school's students, and education for school meals or food nutrition. The satisfaction of school meals in urban and rural school's students are significantly different. Also, the satisfaction of school meals about elementary, middle and high school's students are significantly different. To do this, importance of school meals is to build up the safe agricultural supply system. For safe agricultural supply system, local agricultural products provided in school meals should be supplied based on GAP, HACCP certificated companies such as US FTS(Farm to School) program.

A Single-Plot Visualization of the Relative Importances of All Factors in Optimizing the Response

임성수 한국자료분석학회 2006 Journal of the Korean Data Analysis Society Vol.8 No.5

Two typical objectives of response surface methodology(RSM) are, first, to determine the optimum combination of factor levels, and second, to gain understanding of the characteristics of the response system. This article proposes a graphical display to serve that second objective of RSM. Here, the partial effect of factor j is defined as the effect of factor j when the levels of the other factors are fixed at their optimum values. The partial effects plot is a plot that shows, for j=1,...k, how the response moves as the level of factor j changes in the design region when the levels of the other factors are optimal. This plot allows graphical comparative assessment of partial effects of the factors, and so we can graphically find out which factors are relatively more important in optimizing the response and which factors are not so. A real data set from a lettuce cultivation experiment was used for illustration.

기본 무특성 성분 및 각 성분 비율의 제한적 구간 존재 시의 혼합물 성분 비율 조합의 최적화

임성수,정형철 한국자료분석학회 2013 Journal of the Korean Data Analysis Society Vol.15 No.6

본 연구는 혼합물 실험에서 기본 무(無)특성 성분과 각 성분 비율의 제한적 구간이 존재할 때 혼합물의 특성치를 최적화하는 성분비율 조합을 찾아내기 위한 방법을 제안한다. 일반적인 혼합물 실험 설계에는 특정 성분이 100%를 차지하거나 0%인 설계점들도 들어 있으므로, 우리의 상황에서는 보통의 혼합물 실험 설계를 사용할 수 없다. 본 논문에서 제안하는 방법에서는, 혼합물이 k개의 성분으로 이루어진다고 할 때, 기본적인 성분이지만 혼합물의 특성을 결정짓지 못하는 성분을 성분 k로 놓고, 이 성분을 제외한 나머지 성분의 각 구간 내 퍼센티지 값들을 요인 수준들로 하는 일반적인 (k-1)-요인 반응표면설계를 작성한 후에 성분 k의 퍼센티지는 100에서 나머지 성분들의 퍼센티지 값의 합을 뺀 것으로 하여 실험실시용 k-성분 설계를 완성하고, 이를 이용하여 실험을 실행한 후에 반응표면분석을 통하여 성분 1부터 성분 (k-1)까지의 최적 퍼센티지들을 찾아내고, 성분 k의 최적 퍼센티지 값은 100에서 성분 1부터 성분 (k-1)까지의 최적 퍼센티지들의 합을 뺀 값으로 정한다. 5-성분 혼합물 실험의 예시적 설계 및 분석을 통해 방법을 설명한다. This article proposes how to search for the component-proportion combination that optimizes a characteristic of a mixture in the presence of the basic and featureless component and the restrictive intervals of component proportions. Ordinary mixture designs cannot be used in this situation because they contain the design points at which some component has a proportion of 1 or 0. Suppose that the mixture of interest consists of k components. The method proposed here starts with setting aside the basic and featureless component and calling it component k. Then, construct a response surface design in the coded levels of the proportions of components 1 through (k-1). In the experimental design in actual proportions, the proportion of component k is set to be 1 minus the sum of the other (k-1) proportions. Then, perform the experiment and analyze the experimental data to optimize the proportions of components 1 through (k-1). The optimum proportion of component k is set to be 1 minus the sum of the other (k-1) optimum proportions. This method is illustrated though the design and analysis of an experiment with a five-component mixture.

임술민란기 秋琴 姜瑋의현실인식과 三政改革論

임성수 조선시대사학회 2016 朝鮮時代史學報 Vol.79 No.-

임술민란은 19세기 조선사회의 각종 모순으로 인해 농민들의 불만이 일시에 폭발하면서 발생하였다. 정부는 민란을 진압하고 민심을 수습하기 위해 삼정이정청을 설치하여 민란을 유발시킨 가장 큰 원인으로 지목되었던 삼정문제에 대한 대책을 강구하였다. 이와 함께 삼정문제의 해결방안을 묻는 철종의 책문에 부응하여 많은 지식인들은 應旨三政疏를 올려 삼정이정청의 활동에 방향을 제시하였다. 강위는 민란이 발생하였던 양남지방에서 생활하면서 농민들의 생활과 삼정문제를 목도하였다. 이러한 경험을 토대로 강위 나름의 삼정에 대한 견해와 해결방안을 제시한 것이 「擬三政捄弊策」이다. 강위의 구상은 비록 국왕에까지 보고되지는 못하였지만 당시 향촌사회의 현실과 왕조정부의 운영 실태를 파악하는데 큰 도움을 준다. 강위는 당대 여러 지식인들과 마찬가지로 삼정문제를 민란이 발생한 직접적인 원인으로 판단하였다. 그러면서도 그는 인재를 제대로 등용하지 못하고 인사제도가 문란해 진 것이 삼정문제의 근본적인 원인으로 인식하였다. 특별히 그는 삼정 중에서도 軍政을 강조하였다. 군정이 무너지면서 전국에 병사와 군향이 모두 허술해져 민란이 발생했음에도 진압할 방법이 없다고 보았다. 강위는 三政 문제에 대한 개별적인 개선보다 군제를 정비하여 근본적인 국가개혁을 추구하였다. 그는 강력한 兵勢를 모아 인주의 節制를 세워야만 ‘禁暴止亂’의 힘이 생기며, 외적의 침입도 막을 수 있다고 보았다. 우선 강위는 신분을 구분하지 않고 모든 백성을 징발하여 군역을 균평하게 하는 것이 급선무라 여겼다. 구체적인 방안은 三代의 井田法을 활용하여 8결당 兵士 1명과 兵馬 1필을 내는 형태였다. 이렇게 하면 산술적으로 조선의 원장부 전결 150만결에서 18만 7,500명의 병사와 병마를 확보할 수 있었다. 군병의 통제는 軍伍를 편제하여 단계별로 지휘권을 전달하는 방식을 제시하였다. 또한 현재의 호수․보인체제는 불필요하다는 입장이었다. 강위는 軍制개혁에 필요한 재원과 환곡을 혁파하면서 발생한 재정 손실을 戶口田을 통한 租庸調로 보전하려 하였다. 그는 조용조 방식이 井田制에서 유래되었음을 강조하며, 자신의 개혁론이 결국 三代의 정치를 복원하는 것이라는 점을 상기시켰다. 戶口田을 통한 부세운영의 핵심은 모든 토지와 호구에 부세를 부과한다는 점이었다. 강위는 이를 통해 均 이념을 실현하여 민심을 되찾고 재정을 확충하고자 하였다. 井田制을 활용하여 兵馬를 조달하고, 戶口田을 통해 탄탄한 재정을 확보하면서도 均 이념을 실현하는 것이 강위가 추구한 새로운 국가상이었다. When it comes to Imsul-Year People’s Revolt (1862) in 19thcentury, it is raised because of commoner’s discontent expressed at once. The government established Samjeongiejeongchung to try to solve commoner’s discontent, especially about problem of Samjeong(三政). With this stream, many Confucian scholars suggested solution to this problem with Ungjisamjeongso(應旨三政疏). Gang-wi, one of Joseon scholar who was lived in local of Yangnam, witnessed commoner’s situation and problem of Samjeong. Gang-wi suggested his opinion and solution based on his experience and wrote ‘Uei-Samjeong-Gupyechek(擬三政捄弊策)’. Although Gang-wi’s appeal was not reached for King, however, his suggestion could be a way to investigate local situation and Royal government’s operating system at that time period. Gang wi analyzed cause of people’s revolt was problem of Samjeong, as many contemporary scholar’s opinion. And also he thought disorder of bureaucracypersonal affair was fundamental cause of Samjeong problem. He especially emphasized Gunjeong(軍政, military administration) which is one of the Samjeong. He thought there was no way to suppress people’s revolt because of military administration disorder. Gang-wi thought establishing military administration is more important than other problems. He thought first thing to do for the revolution is strengthen the army and King’s authority to defense enemies. For this, he emphasized that people have to take part in duty of military without status or position. His suggestion was that based on ancient system of Jeongjun(井田), 8 gyeol of ground prepare 1 solder and 1 hourse. With his suggestion, Joseon could secure 187,500 of solders and houses based on 1500,000 gyeol of ground. And he suggested Guno(軍伍) system to control this new military system and Hosu and Boin system, Joseon’s old military system, is no more necessary. Gang-wi proposed an alternative to new military system through Jo-Yong-Jo(租庸調) system based on Hogujeon(戶口田). He mentioned Jo-Yong-Jo system was originated from Jeong-jeon system(井田制) and his plan of revolution was a way to recover ideal ancient government system. Operating financial system based on Hogujeon was meaning that collecting tax for every ground and census. With this system, Gang-wi planned to conduct the ideology of Gyun(均) and recover people’s attention and expand a budget.

임성수 한국유기농업학회 2016 韓國有機農業學會誌 Vol.24 No.2

To internalize climate-related external costs from agricultural production and food consumption Pigou taxes and carbon credits increase private costs for food. Voluntary GHG reduction program for carbon-neutral food can be advantageous over such policy measures since they avoid higher food prices for the poor. The pilot project of low-carbon agriculture certification system is to reduce GHG emissions from agricultural production and enhance the competitiveness of domestic agricultural products. This study examines producers’, distributors’, and consumers' perceptions of the low-carbon agriculture certification system and analyzes alternatives to promote the low-carbon certificated agricultural products.

교통혼잡시 동태적 교통시간산정에 관한 연구

林聖洙,李仁遠 弘益大學校 科學技術硏究所 2000 科學技術硏究論文集 Vol.11 No.-

Travel time function which is currently used in Traffic Assignment is BPR function. Monotonous increase BPR Function is made by relationship between Traffic Volume and Travel time. As it is simplified for convenience of mathematical calculation, cant explain the real situation in traffic flow such as Capacity Drop. Also It must be developed for providing the real time travel information that new travel time function which is precisely reacted at the change of Traffic flow. The main idea of this thesis is to develop a realistic travel time function that is based on the headway, one of the main characters of microscopic traffic flow. In order to establish solid model, the study used data which are collected in "KangBuk" freeway between Hangang Railway Bridge and Hangang Bridge, Hannam Bridge and Banpo Bridge and the summary of the result is as follows. The function of travel time, set by the independent variable that is accumulation of output-input headway, must be settled in two patterns in order to correctly describe size of traffic and traffic condition such as backward bended curve of travel time, non-reversal and, multiplicity; when traffic congestion gets increased and decreased. However, although the forecasting ability of Ran's function of travel time was found to be relatively high, but they were also found that they did not reflect non-reversal, multiplicity that can be observed from the reality. This study result suggests that forecasting method of traffic time that uses headway is simple in formula and holds high accuracy in traffic characters. Also, it can explain the traffic condition in more correct way by calculating the traffic time using headway and it can provide real time traffic information. If it is possible to make an additional revision in precondition of delay time resulted from passing and changing lines, it is should be able to realistically estimate dynamics in traffic flows when it is adapted to the various kinds of traffic management method such as ramp metering in merging sections on freeway.

혼합물 (mixture) 실험은 최적 반응치를 산출시키는 혼합물의 구성성분비를 찾기 위한 실험이다. 혼합물 실험에서는 구성성분비의 합이 1이라는 제약조건 하에서 실험의 설계와 분석이 수행된다. 본고는 식품의 저장성 향상에 관한 어느 연구에서 실시된 실험을 이용하여, 혼합물 실험의 설계와 분석을 예시한다. 이 실험에서, 설계로는 augmented simplex centroid design이 사용되었고, 분석을 위하여는 Poisson log-link mixture polynomial regression과 nonlinear programming이 사용되었다. Experimentation with a mixture is to find a set of proportions of mixture components for response optimization. In mixture experiments, designs and analyses are under the restriction that the sum of the component proportions is 1.This article illustrates design and analysis of a mixture experiment using an experiment performed in a study for improvement of flood storage. In this experiment, an augmented simplex centroid design was used as an experimental design, and Poisson log-link mixture polynomial regression and nonlinear programming were used for analysis.

조선후기 戶曹의 田稅 부과와 給災 운영 변화

임성수 서울대학교 규장각한국학연구원 2017 한국문화 Vol.78 No.-

Stable taxation management was of the utmost importance because the revenue of the ministry of taxationwas absolutely dependent on the land tax. Land, however, was the most important means of production for the farmers to maintain their household and livelihood. Therefore, the government had to provide the farmer's reproduction base, but had to be taxed at an appropriate level to secure necessary revenues. When it comes to the Gupje(給災), it was the government's land management system that gave tax-free benefits to disaster-affected land.After operated the Bichong regulations, the Gupje became the most important variable in determining the size of the tax grain. The Samokje(事目災) that provided from the ministry of taxationbecame the Bichong regulation’s main source of income, and supported by the Gachungje(加請災) became a basic operating system. Although this kind of operating method was maintained at the beginning, soon the ratio of the two reversed, and operation of Gachongje that handled by Gamsa became main system.Since the 19th century, the gap between Samokje and Gachungje has increased, and finally the unit of Samokje fixed 100gyeol, 200gyeol and became formally. The overall scale of the Gupje has shown a gradual decline since the nineteenth century, but it has fallen sharply in the latter half of the 19th century and has risen again.It is easy to imagine that this decline would have led to a pre-emptive rise in farmers; however, the tax-paying land was also declining.
