When it has been rained, forecasting flow at basin is difficult methods, for it is strongly nonlinear elements since old time hydrologists have tried to analyze flow. As a results, a number of methods have been developed existing models base on topographical map, drawing map, or observation data are solved by hand and simple calculation. However, these methods require many time and effort, and the results are in accurate. This study on it is simulates rainfall-inflow to use hydrologic models at Yongdam Dam basin area and evaluate HEC-1 Model in WMS(Watershed Modeling System). When synthetic unit hydrograph compared real date using HEC-1 in WMS, Clark & SCS methods are good accuracy, where as Snyder method is bad accuracy.

고상추출카트리지를 이용한 잔류농약 다중분석과정에서 정제용매에 따른 회수율 비교

두옥주,정보경,김경식,정의근,김진곤,김명희 한국환경농학회 2002 한국환경농학회지 Vol.21 No.2

채소류 중 비교적 matrix효과가 적고, 수분 함량이 적절하여 회수율이 양호한 오이를 대상으로 하여 총 16종의 농약 성분을 A, B 두 group으로 나누어, 농약의 동시 다성분 분석의 전처리 과정 중 정제에 사용하는 용출용매로서 5%~20%의 acetone/hexane과 5%~20%의 ethyl acetate/hexane을 사용하여 각각의 회수율을 분석하여 얻은 결과는 다음과 같다. Acetone/hexane을 사용한 경우 5% acetone에서 총 16종의 농약 성분 중 ethalfluralin, trifluralin, chlorothalonil 등 11종의 농약은 높은 회수율을 보였으나, alachlor와 iprodione, endosulfan sulfate, bifenthrin, fenarimol은 매우 낮은 회수율을 나타내었고, 10% 이상의 acetone/hexane에서는 bifenthrin과 fenarimol 제외한 14종의 농약에서 높은 회수율을 얻을수 있었다. 그러나 bifenthrin은 20%의 acetone/hexane을 사용한 경우는 용출되지 않았고, fenarimol은 10% 이하의 acetone/hexane을 사용하였을 때는 낮은 회수율을 나타냈었다. Ethyl acetone/hexane을 사용하여 총 16 종의 농약 성분의 회수율 분석을 한 결과, 5% ethyl acetone에서 ethalfluralin, α-endosulfan, β-endosulfan (A group), vinclozolin, tetradifon, cyprethrin, fenvalerate (B group)에서만 70% 이상의 회수율을 얻었다. 10%의ethyl acetone/hexane을 사용하여 분석한 경우는 trifuralin, chlorothalonil, α-endosulfan, β-endosulfan, endosulfan sulfate(A group), vinclozolin, procymidone, tetradifon, cypermethrin, 그리고 fenvalerate(B group) 에서는 70% 이상의 회수율을 얻었고, 20%의 cthyl acetone/hexane 을 사용하여 분석한 경우는 5%나 10%의 ethyl acetone/hexan 을 사용하여 분석했을 때보다 좋은 결과를 나타내어 전체 16종의 농약 중 14종에서 75% 이상의 회수율을 얻었으나, alachlor와 bifenthrin은 매우 낮은 회수율을 보여서 ethyl acetate 와 hexane의 혼합용매가 이들 두 농약성분의 분석에는 적합하지 않은 용출 용매임을 알 수 있었다. A study was carried out to optimize the cleanup step using a solid-phase extraction (SPE) cartridge, SupelClean^(TM) Florisil, for multiresidue analysis of 16 pesticides in cucumber matrix. Eluting efficiencies of two solvent systems including acetone/n-hexane and ethyl acetate/n-hexane mixtures were critically evaluated by recoveries of target anaytes from the SPE Florisil column. Based on the recovery as a measure of eluting efficiency, an acetone/n-hexane (20/80,v/v) mixture provided more than 80% recovery for 15 pesticides except bifenthrin. In case of ethyl acetate/n-hexane, 14 pesticides showed recoveries higher than 75%, while those for alachior and bifenthrin were less than 30%.

점필재 김종직의 政敎와 講學의 서정 -함양군수 시기를 중심으로-

( Gyung Ju Jung ) 경상대학교 남명학연구소 2013 남명학연구 Vol.39 No.-

점필재 김종직은 조선초기 사림의 종사이다. 그가 조선조 도학의 선구자로 일컬어지는 것은 그 자신이 문학과 학문에 있어서 탁월한 성취를 보여주었을 뿐만 아니라, 지방 행정을 통하여 인륜 도덕을 숭상하는 사회 기풍을 일으키는 모범적인 사례를 보여주었고, 그 문하에 도학의 이념을 실천하는데 앞장선 훌륭한 후학들을 양성해내었기 때문이다. 점필재의 도학 이념에 입각한 정치 교화와 교육의 실천 모범은 그가 지방관으로 근무하였던 10년 동안에 가장 잘 나타난다. 이런 관점에서 이 글에서는 점필재가 함양군수로 봉직하였던 5년 동안의 시문 가운데 정사를 임하는 태도와, 풍교의 대책과 강학 및 유상의 정서를 추적하여, 점필재의 평소 학문 사상과 정치 교육의 성과가 조선전기 도학의 선구임을 밝히고자 하였다. 점필재는 함양군수로 부임하면서부터 수시로 관내를 순시하면서 지역의 역사와 물산, 홍수의 재해, 조세와 부역 등, 民生에 대한 깊은 관심과 애정을 보여주었고, 함양읍성 나각을 보수하고 다원을 경영하는 등 조선초기 지방관원으로서 그 유례를 찾아보기 어려울 만큼 고을 주민의 편익을 위한 적극적인 대책을 강구하여 시행하였다. 그는 또한 향교를 보수하고 향교를 중심으로 향음 향사 양로의 의식을 거행하여 인륜 도덕으로 풍속을 순화한다는 風敎의 실현 가능성을 보여주었으며, 한편으로 많은 문생들을 받아들이고, 그 문생들과 고을 주변의 산천을 다니면서 수시로 학문의 중요성을 일깨우고 도학과 심학의 단서를 열어주었다. 점필재는 함양군에서 시행한 시정과 풍교 강학의 규범은 이 시대 학자들에게 도학 정치 실현의 한 가능성을 보여주었고, 그의 문하에서 배출된 인재들은 조정의 관료나 재야의 문인 학자로서 그의 모범과 신념을 널리 확산함으로써 한 시대의 새로운 조류를 형성하였다. 그런 점에서 함양은 점필재 김종직의 학문 사상과 경륜이 구체적인 모습으로 드러나 조선조 도학의 본류를 형성하는 전환처였다고 할 수 있을 것이다. Jeompiljae(占畢齋) Kim-Jongjik(金宗直) was the best pioneering practical confucian scholar, and he was famous for outstanding literature and excellent poet in early Joseon Dynasty. About his academic and literary achievements, a lot of papers had been submitted. In this article, from a slightly different perspective, I summarized the achievement of Jeompiljae in three viewpoint, such as one of the provincial administrators, and as one of the excellent educators, and one of the active cultural planners. Kim-Jongjik was appointed as the Governor of the Hamyang when he was 41 years old. As governor of Hamyang[咸陽郡守], He first closely observed the living conditions of the inhabitants, and he tried to grasp the reality of local agricultural production, and he poured his energy to establish measures to prevent droughts and floods. He was trying to fulfill his responsibilities as a bailiff, to eliminate poverty and hunger of the inhabitants. Among these some corrective policy, people like to say Kim-Jongjik``s most successful achievement by two viewpoint. He constructed the long-tiled roofs[羅閣] that protect the castle built with soil. This plan had reduce the burden of heavy corvee of residents for many years. He planted tea trees and made tea-production farms, and that local authorities were responsible of that management for it. It contributed to reducing the burden on local residents of tribute paid. As a provincial administrators, and as a Confucian scholar he had practiced his political beliefs, and faithfully performed his responsibilities. One of the important achievement of Jeompiljae was to educate people through edification. He had a deep interest in to foster people of the high grade in moral character. So he had been put a lot of effort in to educate the students and to construct schools. As the result of these efforts, in according to his teachings some students had been passed the test for selection of the management. They were selected as the ruler of the dynasty, and more students gathered to ask him to find the correct way for true Confucian. Due to these efforts, some great moralist teachers such as Kim-Koengpil(金宏弼) Jeong-Yeochang(鄭汝昌) who was the good example to the Confucian students of the Joseon, had been appeared here. Because of these several reasons, we can say that was the most vigorous rewarding time of the Kim-Jongjik’s life.

Simulation and Design of Forging Process for a Gear with Inner Cam Profile using FEM

Gyung-Ju Kang(강경주),Jeong Kim(김정),Beom-Soo Kang(강범수) 대한기계학회 2005 대한기계학회 춘추학술대회 Vol.2005 No.5

The gear-shaped mechanical elements have been generally machined with gear hob or grinding tool to improve its dimensional accuracy and surface quality due to the complicated shape. This paper deals with the gear-shaped mechanical element with complicated configuration, which is consisted of outer involute gear and inner cam profile, and the optimal dimension of the initial slug to manufacture the component. In order to find out concrete information of the cold forging process, the elastic deformations of the die and workpiece were also evaluated by using the elastic and elasto-plastic finite element method to improve the dimensional accuracy of the gear-shaped element. Finally, these results were verified with the experiment of the gearshaped mechanical element.

Theoretical Examination of the Pay-for-Performance Practice: Case of a Shipbuilding Company

Gyung-Ju Jun 한국항해항만학회 2013 한국항해항만학회지 Vol.37 No.5

Pay-for-performance plans are some of widely used human resource practices in many firms, including shipbuilding, for productivity and motivational improvement purposes. Such plans play an important role in industries that are highly labor-intensive, and where effective management of human resources is critical to business operations, such as the shipbuilding industry. Those practices can have large impact on employee performance and ultimately company competitiveness. Research studies that show how such incentive plans improve productivity and reported pattern of adoption by firms have spurred the use and adoption in many firms. However, there are also researchers who point out that there are negative consequences to using incentive plans. Therefore it is important for companies to carefully consider the practices they use. In this paper, I discuss research findings that support the practices and critical viewpoints related to pay-for-performance plans. Research findings from Korean literature are, then, discussed. The shipbuilding industry is chosen because proper human resource management is critical in reducing turnover and increasing employee satisfaction. Through a shipbuilding company case, problems related to using pay-for-performance incentive plans and how they affect work-related issues of employee morale, cooperation, and teamwork will be discussed. While positive aspects have been emphasized to drive greater adoption among firms, the resulting consequences of the pay plans need to be seriously considered and improvements upon the plans made by firms. Improvement suggestions are discussed in the conclusions and implications.

Social Influence on Ethical Behaviors in Organizations

Gyung Ju Jun(전경주) 한국산업경제학회 2019 산업경제연구 Vol.32 No.6

사회적인 영향은 직장에서 피할 수 없는 부분이므로, 비윤리적인 행동에 관하여 직장에서 직원이 상사와 동료들로부터 받는 영향을 본 연구에서 살펴보았다. 조직은 윤리적인 문제에 대해여 더 이해를 하여야 하며 윤리적인 문제가 발생할 수 있는 부분을 잘 관리할 의무가 있다. 과거 연구에서는 상사와 동료들이 업무 환경에서 직원에게 주는 영향이 있다고 하지만, 집단적인 사회에서는 그 영향력이 더 강하게 작용할 수 있다. 직장 업무 환경에서 직원에게 주는 영향을 differential association 이론을 통하여 비윤리적인 행동을 더 이해하는데 기여하고자 한다. 부산, 경남지역 직장인들을 상대로 설문조사를 하였으며 regression 분석을 통한 연구 결과는 다음과 같다. 상사는 정(+)의 영향을 미치는 것으로 나타났지만, 동료들은 부(-)의 영향을 미치는 것으로 나타났다. 윤리적인 부분에 있어서 동료의 영향보다는 상사가 더 영향을 줌으로 상사의 행동이 더 중요하고 어떤 경우에는 절대적인 영향을 준다고 볼 수 있다. 그러므로 상사의 윤리, 도덕적 행동을 통제하기 위해서는 조직차원에서 직원들의 행동교육과 훈련에 관심을 가져야 한다. Social influence is inevitable in work situations. In situations dealing with ethical matters, it is of particular importance for organizations to understand and take action to manage potential occurrences of ethical problems. This paper examines the influence of those in the immediate job context of employees and how the manager"s and coworkers" ethical behaviors influence an employee"s decision to get involved in ethical or unethical conduct. Though research has shown the effect of the social influence of those around an employee, the strength of the social influence is far greater and stronger in a collectivist culture society. Theory of differential association is used to theoretically explain the relationships. In this study, using the data collected from employees in large companies in Busan and Kyungnam province, conducted regression analyses to test the hypotheses. The results showed that the supervisor had a positive effect on the employees but the coworkers did not have the same effect on the employees. From this we can conjecture that with regards to ethical matters, the supervisors have larger influence than one"s coworkers, and, therefore, supervisor"s ethical behaviors are more important. Empirical examination of the relationship of some of the factors influencing employee"s decision to behave ethically or unethically provides understanding for companies in managing potential ethical risk areas. In conclusion, companies can use the results of this study to establish a clear ethics guideline for employees to follow and ethics training programs.
