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.

This study addresses the changes in the 20th architectural education of the United States, focusing on investigating the changes in the inter-relationship between the educational needs and the educational contents. The research results reveal that there have been a lot of changes in the educational needs and the contents; the changes can be categorized into three distinctive periods such as the period of using educational resource-oriented standards, performance-based standards, and integration-based standards. By doing this research, it will be possible to recognize a mechanism which effectively improve the educational system in such a way of meeting the needs from the architectural practice. Thus, although this research deals with the education of the United States, it would be employed for launching and improving the architectural accrediting system in Korea.

Factor XI deficiency is a very rare congenital coagulation disorder. Bleeding complications should be consideredwhen treating a patient with unstable angina and congenital coagulation disorder during and after percutaneouscoronary intervention (PCI). Thrombotic complications can develop after fresh frozen plasma (FFP) transfusionand drug-eluting stent (DES) implantation. We report here on the successful management of a patient havingunstable angina with factor XI deficiency, and this patient was treated with PCI under intravascular guidance andwith the aid of FFP and hemostatic devices.

Development of an E. coli Expression Cassette for the Efficient Production of a Harmful Protein

이상현,하종명,이재화,하배진,Hwan Jong Kwak,Ok Soo Kim 한국생물공학회 2004 Biotechnology and Bioprocess Engineering Vol.9 No.5

In order to produce a harmful protein more efficiently, this expression cassette, dubbed pCol-MICT, is directed by the colicin promoter, and was constructed by the insertion of a rrnBT1T2 fragment of pEXP7, and a MxeInteinCBD fragment of pTXB3, into pSH375. To test whether harmful proteins, including proteolytic enzymes, could be effectively produced by this cassette, the carboxypeptidase (CPase) Taq gene was inserted into the pCol-MICT cassette to yield pCol-CPaseTaq-MICT. E. coli W3110 cells harboring pCol-CPaseTaq-MICT produced a large quantity of this enzyme, as much as 47.2 mg of purified from per liter of culture, when cultured in the presence of mitomycin C (0.4 g/mL). This indicates that the colicin promoter-controlled E. coli expression cassette was able to produce almost 8 times of protein than the conventional tac promoter-based system, and that this cassette may be useful in the synthesis of other harmful proteins.

초등학교 통합학급 교사의 직무스트레스와 소진에 관한 연구

이상현,박찬희 한국청각언어장애교육학회 2016 한국청각·언어장애교육연구 Vol.7 No.1

This study examined the job stress of teachers in integrated education and the characteristics of the burnout according to the variables, including, gender, career of teaching, the level of students' handicap, the number of students with handicap, and spouses' occupations. With this, the study aimed to find the basis for successful integrated education. The subjects were 140 teachers of integrated classes in elementary schools. The method of this study was a survey, using questionaries made by Kang, Hak-Gu. His questionary is modified Wilson(1981)'s ‘Stress Profile for Teacher (STP)’ and Maslach & Jackson(1981)'s ‘MBI (Maslach Burnout Inventory)’ to fit in for Korean situation. The results were tested with t-test, F-test, and Pearson's simple correlation in SPSS/WIN(version 10.0). The followings are the findings. First, teachers have high stresses in teaching and administrative works and then in the relationship with students and working conditions. Let's look at how each individual variable affects on the job stress. In gender, female teachers have a little higher mark than males teachers on the job stress, but statistically, there is no significance. So gender does not affect on stress level among teachers. The more career of teaching the less job stress. The stress level is ranked high in teachers with less than 10 years of career of teaching. Then, respectively, teachers with more than 10 years and less than 20 years of career of teaching and teachers with more than 20 years of teaching, have less stress level. The level of students' handicap are also found to be related to the job stress. Compared to students with mild handicap, when students have severe handicap, teachers experience the high stress level. The more severe level of handicap the higher job stress in teachers. The number of students with handicap dealt with teachers are also caused the high level of stress. Teachers with one student with handicap experience lower level of stress than teacher with more than one student with handicap do. The spouses' occupation also affects on the job stress of teachers of integrated classes. Teachers with spouses whose occupations are office workers have slightly higher level of stress than ones with spouses who are teachers but relatively higher level than ones with spouses whose occupations are self-employers and others. Next is about teachers burnout. Teacher experience burnout when they feel emotional exhaustion. Based on the variables, teachers have different level of burnout. Female teachers feel slighter burnout than male teachers but there is no statistically significance. The more career of teaching the less experiencing burnout. Feeling of burnout is ranked high in teachers with less than 10 years of career of teaching. Then, respectively, teachers with more than 10 years and less than 20 years of career of teaching and teachers with more than 20 years of teaching experience less burnout. Teacher feel more burnout with students with severe handicap than those with slight handicap. The more number of students with handicap the more feeling burnout. Teachers with one student with disability experience less burnout than ones with more than one student with disability. Teachers are vulnerable to feeling burnout when they have more than one students and students with severe handicap. Spouses' occupations also affects on teachers feeling burnout. Teachers with spouses whose occupations are office workers and teachers have higher level of burn out than those with spouses whose occupations are self-employers and others. Third, there is a high correlation between the job stress and the burnout of integrated class teachers. The minor effects of burnout and job stress has relatively higher correlation; for example, emotional exhaustion and job stress(r=0.79), and feeling loss of personal accomplishment and job stress(r=0.64). In the relationship between the minor effects of job stress and burn out, there are high c... 이 연구는 초등학교 통합학급 교사의 직무스트레스와 소진에 대하여 알아보기 위한 것으로, 초등학교 교사 140명을 대상으로 설문지를 사용하여 조사하였다. 연구결과는 다음과 같다. 첫째, 통합학급 교사의 전반적인 스트레스 경향은 사회적 지원과 수업지도 및 잡무에서 유의미한 차이를 보였다. 둘째, 통합학급 교사가 지각한 소진경험의 전반적인 경향을 살펴보면, 교사의 개인적 성취감 상실이 가장 높은 소진경험으로 연결되는 것으로 나타났다. 셋째, 통합학급 교사의 직무스트레스와 소진과의 관계는 높은 상관성을 나타내었다. 따라서 이 연구는 다양한 교육 환경에 직면해 있는 통합학급 교사들의 직무스트레스와 관련된 교육현장 여건개선의 기초자룔 제공하는데 그 의의가 있다
