보증 클레임 시계열 데이터를 위한 퍼지 PID 제어

이상현,이상준,문경일,조성의 한국IT서비스학회 2009 한국IT서비스학회지 Vol.8 No.4

Objectifying claims filed during the warranty period, analyzing the current circumstances and improving on the problem in question is an activity worth doing that could reduce the likelihood of claims to occur, cut down on the costs, and enhance the corporate image of the manufacturer. Existing analyses of claims are confronted with two problems. First, you can’t precisely assess the risks of claims involved by means of the value of claims per 100 products alone. Second, even in a normal state, the existing approach fails to capture the probabilistic conflicts that escape the upper control limit of claims, thus leading to wrong control activities. 1 이상현·이상준·문경일·조성의 To solve the first problem, this paper proposed that a time series detection concept where the claim rate is monitored based on the date when problems are processed and a hazard function for expression of the claim rate be utilized. For the second problem, this paper designed a model whereby to define a normal state by making use of PID (Proportion, Integral, Differential) and infer by way of a fuzzy concept. This paper confirmed the validity and applicability of the proposed approach by applying methods suggested in the actual past data of warranty claims of a large-scaled automotive firm, unlike hypothetical simulation data, in order to apply them directly in industrial job sites, as well as making theoretical suggestions for analysis of claims.

Traditionally, History and Philosophy has been in the center of Human science. It has offered the leaders the principle for the national or social guidance. And it has been the spring of information and intelligent for the well educated men. At the last, it provided the fundamental of ideologies; nationalism, socialism(communism) etc. But Since having finished the first and second world war, according to the development of industrial society, the diversification of the subject of study, and the American pragmatism becoming powerful, history has to meet the fate to withdrawal in the struggle for jobs. Nevertheless, we cannot throw up the history. Because if all of the historical records were disappeared on the earth, all of process of human lives also would be drowned into the world of the lapse of memory. Here, we have to research the way to go on studying the new history according to new consciousness of realistic problem. In the future, what and how will the historian do? At the first of all, most of historians have to do a self-reflection and a self-reformation. They must break from the convention; to make an attachment to special field of study and to be satisfied with a study according to his own preference. And They have to try to get close to mass of people. In behalf of this, first of all students of history have to make a foundation of knowledge about general history including various information of multifarious fields. Upon this basement, we must research the problems in the interest on present life and investigate the way of resolve the problems. Second, Historians have to study the way how to use the history in the real life. For example, historians have to announce the role of historic knowledge for making a good democratic society and educating a democratic civil. Third, historians have to search the way how to make a relationship with the history and another school subject. I guess that we, historians are able to connect with the history to diverse school department of subject. Politics, economics, sociology, religion, management etc.

RapidEye 위성영상의 시계열 NDVI 및 객체기반 분류를 이용한 북한 재령군의 논벼 재배지역 추출 기법 연구

이상현,오윤경,박나영,이성학,최진용,Lee, Sang-Hyun,Oh, Yun-Gyeong,Park, Na-Young,Lee, Sung Hack,Choi, Jin-Yong 한국농공학회 2014 한국농공학회논문집 Vol.56 No.3

While utilizing high resolution satellite image for land use classification has been popularized, object-oriented classification has been adapted as an affordable classification method rather than conventional statistical classification. The aim of this study is to extract the paddy field area using object-oriented classification with time series NDVI from high-resolution satellite images, and the RapidEye satellite images of Jaeryung-gun in North Korea were used. For the implementation of object-oriented classification, creating objects by setting of scale and color factors was conducted, then 3 different land use categories including paddy field, forest and water bodies were extracted from the objects applying the variation of time-series NDVI. The unclassified objects which were not involved into the previous extraction classified into 6 categories using unsupervised classification by clustering analysis. Finally, the unsuitable paddy field area were assorted from the topographic factors such as elevation and slope. As the results, about 33.6 % of the total area (32313.1 ha) were classified to the paddy field (10847.9 ha) and 851.0 ha was classified to the unsuitable paddy field based on the topographic factors. The user accuracy of paddy field classification was calculated to 83.3 %, and among those, about 60.0 % of total paddy fields were classified from the time-series NDVI before the unsupervised classification. Other land covers were classified as to upland(5255.2 ha), forest (10961.0 ha), residential area and bare land (3309.6 ha), and lake and river (1784.4 ha) from this object-oriented classification.

영웅소설 번역본의 계보와 문학사적 함의

이상현 부산대학교 인문학연구소 2023 코기토 Vol.- No.99

The purpose of this paper is to examine the genealogy and its meaning of the translation of hero novels published from the late 19th century to the early 20th century. At the end of the 19th century, Korean classical novels moved out of the limited space and time of Korea. For foreigners, Korean classical novels were a Korean language textbook and an important research material to look at to know Korea. Looking at the list of Korean classical novels collected by foreigners, the status of hero novels is very high. On the other hand, there are only four cases in which hero novels have been translated: Im jang gun-jeon(「임장군전」), Jo Woong-jeon(「조웅전」), Baek hak seon-jeon(「백학선전」), and Hong Gil-Dong-jeon(「홍길동전」). Examining the genealogy of the translation of hero novels, it is possible to derive the logic and pattern of selection/exclusion of hero novels in the early modern era. It is not a book enjoyed by Koreans in the past, but a story and a literary work to examine Korean nationality and Korean nationality. 본고의 목적은 19세기 말~20세기 초에 출판된 영웅소설 번역본의 계보와 그 의미를 고찰하는 것이다. 19세기 말 한국의 고소설은 한국과 한국인이라는 제한된 시공간적 경개를 벗어나게 되었다. 외국인들에게 고소설은 한국어학 교재이자 한국을 알기 위해 살펴보아야 할 중요한 연구자료였다. 외국인들이 수집한 경판본 고소설 목록을 보면, 영웅소설 유형의 작품이 차지하는 위상은 매우 높았다. 반면 영웅소설 유형군의 작품이 번역된 사례는 「임장군전」, 「조웅전」, 「백학선전」, 「홍길동전」 4종에 불과하다. 영웅소설 번역본의 계보를 고찰해보면, 근대 초기 영웅소설 작품에 대한 선택/배제의 논리와 그 양상을 도출할 수 있다. 그것은 고소설이 과거 한국인이 향유하던 독서물이 아니라, 한국의 민족지와 한국의 민족성을 살피기 위한 설화이자 문학작품으로 변용/재편되는 모습이다.

Clinical Findings According to Feeding Diets in Very Low Birth Weight Infants: Human Breast Milk versus Bovine Milk-Based Formula

이상현,박재현,김천수,이상락 대한신생아학회 2016 Neonatal medicine Vol.23 No.1

Purpose: We aimed to compare the clinical findings, including morbidity, duration of parenteral nutrition, and length of hospital stay between very low birth weight infants (VLBWIs) fed bovine milk-based formula (BOV) and VLBWIs fed human breast milk (HBM) in a neonatal intensive care unit (NICU). Methods: VLBWIs admitted to the NICU of Dongsan Medical Center, Keimyung University, were enrolled. Infants born from March to August 2014 (n=28) were fed BOV (the BOV group), and those born from September to December 2014 (n=18) were fed HBM (the HBM group). Pasteurized (heating at 62.5˚C for 30 minutes) donor human milk was used if the mother’s own milk was not available because of insuffi- cient breast milk production. Results: The gestational age (28.0±1.7 weeks vs. 27.8±1.4 weeks) and birth weight (1,055±265 g vs. 1,175±187 g), of the infants in the BOV and HBM, groups were similar. In addition, perinatal characteristics were similar between the groups. The duration of parenteral nutrition (36.4 days vs. 24.1 days, P=0.038), length of hospital stay (74.3 days vs.61.1 days, P=0.037), and incidence of nosocomial sepsis (53.6% vs. 22.2%, P= 0.035), significantly differed between the BOV and HBM groups. Furthermore, the frequency of feeding intolerance was higher in the BOV group than in the HBM group, but this difference was not significant. Perinatal cytomegalovirus infection was not detected in any of the infants fed pasteurized donor human milk. Conclusion: Human-breast-milk-based diet for VLBWIs significantly reduces the in- cidence of nosocomial sepsis, duration of parenteral nutrition, and length of hospital stay.

Decision of Abnormal Quality Unit Lists from Claim Database

이상현,이상준,문경일,김병기 한국정보처리학회 2008 Journal of information processing systems Vol.4 No.3

Most enterprises have controlled claim data related to marketing, production, trade and delivery. They can extract the engineering information needed to the reliability of unit from the claim data, and also detect critical and latent reliability problems. Existing method which could detect abnormal quality unit lists in early stage from claim database has three problems: the exclusion of fallacy probability in claim, the false occurrence of claim fallacy alarm caused by not reflecting inventory information and too many excessive considerations of claim change factors. In this paper, we propose a process and methods extracting abnormal quality unit lists to solve three problems of existing method. Proposed one includes data extraction process for reliability measurement, the calculation method of claim fallacy alarm probability, the method for reflecting inventory time in calculating claim reliability and the method for identification of abnormal quality unit lists. This paper also shows that proposed mechanism could be effectively used after analyzing improved effects taken from automotive company's claim data adaptation for two years.
