Multivariate EWMA control charts for monitoring the variance-covariance matrix

정정임,조교영 한국데이터정보과학회 2012 한국데이터정보과학회지 Vol.23 No.4

We know that the exponentially weighted moving average (EWMA) control charts are sensitive to detecting relatively small shifts. Multivariate EWMA control charts are considered for monitoring of variance-covariance matrix when the distribution of process variables is multivariate normal. The performances of the proposed EWMA control charts are evaluated in term of average run length (ARL). The performance is investigated in three types of shifts in the variance-covariance matrix, that is, the variances, covariances, and variances and covariances are changed respectively. Numerical results show that all multivariate EWMA control charts considered in this paper are effective in detecting several kinds of shifts in the variance-covariance matrix.

Multivariate Shewhart control charts for monitoring the variance-covariance matrix

정정임,조교영 한국데이터정보과학회 2012 한국데이터정보과학회지 Vol.23 No.3

Multivariate Shewhart control charts are considered for the simultaneous monitoring the variance-covariance matrix when the joint distribution of process variables is multivariate normal. The performances of the multivariate Shewhart control charts based on control statistic proposed by Hotelling (1947) are evaluated in term of average run length (ARL) for 2 or 4 correlated variables, 2 or 4 samples at each sampling point. The performance is investigated in three cases, that is, the variances, covariances, and variances and covariances are changed respectively.

2019년 대한영상의학회지 개편에 대한 배경: 2018년 회원 설문조사 결과

정정임 대한영상의학회 2019 대한영상의학회지 Vol.80 No.1

Launched in 1964, the Journal of the Korean Society of Radiology (JKSR) has served as the official journal of the Korean Society of Radiology (KSR). However, with establishment of the Korean Journal of Radiology (KJR), an entirely English journal, in 2000 and listing of the KJR in the SCI(E), KJR has become the representative academic journal of the KSR. Therefore, the identity of JKSR needs to be restructured, and a questionnaire survey was conducted to investigate the status and the future direction of the JKSR. The survey was conducted in September 2018 with 10 questions through on-line and mobile, and 553 members gave responses. According to the survey results, about 75% of the respondents read more than one JKSR article a year, mostly through on-line. All types of papers, including original article, case report, and review article were being read. The most common reason for contributing articles to the JKSR was submission for the radiology board examination, and the most common reason for not contributing articles to the JKSR was non-recognition of the publication in JKSR as achievement in universities because JKSR is not indexed in SCI(E). Many respondents were hoping for dealing with continuous medical education and health policies in radiology as the future role of JKSR. Based on these surveys, we plan to reorganize JKSR in 2019, which we would like to introduce in this paper. 대한영상의학회지(이하 대영지)는 1964년 창간이래 대한영상의학회의 공식대표잡지로서 역할을 해왔으나 2000년 영문잡지인 Korean Journal of Radiology (이하 KJR)가 신설되고 KJR이 국제학술지색인에 등재되면서 대표학술지의 중심이 KJR로 옮겨가게 되었다. 이에 대영지의 정체성의 재정립이 필요하게 되었고, 대영지의 독자현황과 앞으로 나아갈 바를 알기 위해 설문조사를 시행하였다. 설문조사는 2018년 9월에 10개의 문항으로 온라인(on-line)과 모바일(mobile)로 시행하였으며 553명의 회원이 응답하였다. 설문조사 결과 대영지는 응답자의 약 75%가 1년에 한 편 이상의 논문을 읽고 있으며 주로 온라인을 통해서 대영지를 접하고 있었다. 원저, 증례보고, 종설 등 모든 논문 종류를 골고루 읽고 있었다. 대영지에 논문을 투고한 이유로는 전문의 자격시험을 위한 전공의 논문 투고가 가장 많았고, 투고하지 않는 이유로는 대영지가 SCI(E)가 아니어서 대학의 업적으로 인정을 받지 못한다는 것이 가장 많았다. 앞으로 나아갈 방향으로 전문의 평생교육과 영상의학과 정책이슈를 다루는 협회지로서의 역할을 더 많은 응답자가 바라고 있었다. 이러한 설문조사를 바탕으로 2019년 대영지의 개편을 기획하였고 이를 함께 소개한다.

원불교 마음공부 기반 인성교육 연구동향과 그 과제

정정임(鄭定任) 원광대학교 원불교사상연구원 2016 원불교사상과 종교문화 Vol.69 No.-

인간성 상실로 인한 사회문제가 대두되고 있는 가운데 인성교육의 다각적 모색이 요구되고 있다. 본 연구는 인성교육의 대안으로 원불교 마음공부 기반 인성교육 연구의 기초를 마련하기 위한 동향과 과제를 파악하는 데 목적이 있다. 이에 원불교 마음공부와 인성교육과의 관계를 알아보고, 인성함양을 위한 원불교 마음공부 연구관련 선행자료 분석을 통해 연구동향을 살펴보았다. 원불교 마음공부를 기반으로 한 인성교육 연구는 1996년 김귀성의 인격교육에 대한 문제 제기를 시작으로 2000년 이후 활발해졌다. 연구방법으로는 실험연구가 8편, 조사연구가 4편, 사례연구, 문헌연구가 각 2편으로 실험연구의 비율이 가장 높다. 대상별 연구 동향은 유아, 중학생, 대안학교 학생, 대학생으로 학령기 청소년이었다. 프로그램에 활용된 원불교 교리는 일상수행의 요법 1조 · 2조 · 3조, 유무념, 일기법이었다. 프로그램 적용 효과는 개인적 측면의 효과보다 사회적 측면의 효과에 더 많은 비중을 두는 경향이 있었다. 원불교 마음공부가 보편적 인성교육의 대안이 되기 위한 향후 과제를 6가지로 정리해 보았다. 프로그램의 체계적 개발과정과 이에 대한 효과검증, 단계별 세분화된 프로그램 개발, 다양한 교리 활용, 보편화된 전달법, 대상을 성인으로 확대, 끝으로 마음공부와 인성교육의 관계를 명확히 할 필요가 있다. 본 연구의 의의는 원불교 마음공부와 인성교육의 관계에 대한 이론적 기초 마련과 연구동향 분석을 통한 관련 프로그램 개발 및 연구의 발전적 방향을 제안할 수 있다는 점이다. Recently, in the rising of the social problems caused by the loss of humanity, it is necessary to look character education in multiple ways. This Study explores a research and trend in character education based on Won-Buddhist Mind Practice. For the purpose of the study, the study discovered a link between character education and Won-Buddhist Mind Practice an alternative in recovering from a sick society, and examined the trend of a study to build an upright character through a preceding research analysis. The study of character education based on Won-Buddhist Mind Practice started by raising a question about character education by Gui sung Kim, and began in earnest 2000. Under the types of research, an experimental research accounted for the largest portion, 8 experimental researches, 4 survey studies, 2 case studies and 2 literature researches. The study trends by subjects were school-age youths such as young children, students in an alternative school and university students. The doctrines used for the program were the essential dharmas of daily practice 1 to 3, checking mindfulness, diary of Won-buddhism. In the effect of application, social aspects more showed an upward tendency than personal aspects in subareas of building an upright character. The tasks of Won-Buddhist Mind Practice to become an universal character education in the future are as follows: A systemic development process of the program and verification of the effectiveness, phasing of program development, utilizing various doctrines, generalized transfer methods, research methods expanded to the general public and clarifying relationship between mind practice and character education. The study had significance for establishing a theoretical foundation in regard to relationship between Won-Buddhist Mind Practice and character education, developing related programs through analyzing the study trends and proposing a development plan.

도급, 용역, 위탁등 관계에 적용되는 중대재해처벌법상 규정의 해석

정정임 한국노동법학회 2024 노동법학 Vol.- No.89

Previously, the role of sanctions, such as preventive administration and punishment for industrial accidents, was mainly played by the Occupational Safety and Health Act(OSHA). However, the OSHA and subordinate laws stipulate the implementation of professional and technical duty obligations, so on-site middle managers are responsible for non-compliance, and there were not many cases in which senior management was sentenced to punishment even when an actual industrial accident death occurred. In particular, in the process of establishing multi-tiered contracting relationships and engaging in profit-making activities, industrial accident prevention measures were not properly implemented for workers belonging to small-scale supply companies that contributed to the operation of the business. As a result of repeated incidents of workers dying, a social trend was formed calling for legal sanctions that could practically guarantee the prevention of industrial accidents at industrial sites that occur during the company's profit-making activities. As a result, the OSHA, which significantly strengthened the mandatory regulations for contractors, was completely revised, and the Serious Accidents Punishment Act(SAPA), which broadly stipulated the criminal liability of senior management (especially of contracting companies), was enacted and implemented. The SAPA is an uneconomical legislation as it is an overlapping regulation as the same and similar obligations are stipulated in the OSHA, etc., even two years after its implementation during the legislative process. Although it is a special criminal law, the structural requirements are not clear and it imposes heavy punishment and punitive damages. There was a lot of criticism that the regulation had too much influence on the industry. Taking these criticisms into consideration, this article examines the meaning of substantive governance, operation, and management, which are indicators of relationships such as contracts, among the provisions of the SAPA applicable to relationships such as contracts, services, and consignments, as well as the subject of obligation and the subject of protection. Review the interpretation of the regulations. The SAPA has no definitions regarding relationships such as contracting, and does not distinguish between the contents of obligations corresponding to the legal status according to contractual relationships in the definition of workers subject to protection, so in the future, the subject of obligation, the subject of protection, and the contents of obligations must be distinguished separately. Therefore, it needs to be clearly defined. In addition, under the current law, when interpreting the limitations on the scope of liability in Articles 4 and 5, there is no choice but to follow the normative interpretation of the contract relationship under the OSHA, so in fact, there is no practical benefit in separately stipulating Articles 4 and 5. It seems also believed that this should be revised in the future to increase the predictability of offenders and the effectiveness of law enforcement by defining the SAPA more clearly and systematically in relation to the OSHA.

급성 신부전 흰쥐에서 Gd-DTPA가 신장에 미치는 영향

정정임 대한영상의학회 1997 대한영상의학회지 Vol.37 No.4

Purpose : To evaluate the nephrotoxicity of Gd-DTPA in rats with normal renal function and in those with acute renal failure, using 0.1mmol/kg and 0.3mmpl/kg in each group. Materials and Methods : Sixty rats weighing 200-250gm were divided into two groups : normal (N) and glucerol induced acute renal failure (F); this was induced by intramuscular injection of 50% glycerol(10ml/kg). Each group was divided into was induced by intramuscular injection of 50% saline (0.15 M NaCl) via the tail vein, while subgroups 2 and 3 were given 0.1 mmol/kg Gd-DTPA and 0.3mmol/kg Gd-DTPA, respectively. Blood and 24-hour urine were collected before and on the first and second day after intravenous injection of either physiologic saline or Gd-DTPA.In order to obtain pathologic specimens, two additional rats in each group underwent the same experimental procedure, and on the first or second day after intravenous injection of saline or Gd-DTPA, both kidneys were removed for ligh microscopic examination.Serum creatininer(Cr), urine creatinine, and several urinary enzymes such as alkaline phosphatase (ALP), gammaglutamyl transferase(GCT), N-acetyl-$\beta$-glucosaminidase ($\beta$-NAG) and lactic dehydrogenase (LDH) of 24 hour urine were measured, and creatinine clearance (Ccr) was calculated.Results : The results were as follows.1. In the group with normal renal function, levels of serum creatinine and urinary enzymes remained unchanges after infusion of 0.1mmol/kb Gd-DTPA or 0.3mmol/kg Gd-DTPA.2. Among rats with acute renal failure, no difference in serum creatinine and urinary enzyme levels between the saline injection group and 0.1mmol/kg Gd-DTPA injection group was noted.3. Among rats with acture uremia, $\beta$-NAG, LDA and ALP were significantly higher on post-injection days 1 and 2 in the 0.3mmol/kg Gd-DTPA injection group than in the physiologic saline or 0.1mmol/kg Gd-DTPA injection group.4. Light microscopic examination of rats with normal renal function after Gd-DTPA injection revealed no significant pathologic change. Those with acute renal failure rats revealed some degree of vacuolization and/or necrosis of renal proximal tubular epithelial cells. No difference was fouds, however, brtween the saline and Gd-DTPA injection subgropus.Conclusion : In conclusion, Gd-DTPA was safe in rats with normal renal function, even when the dose was tripled(0.3mmol/kg), and was safe in those with acute renal when the standard dose (0.1mmol/kg) was given. In this latter group, however, a triple a triple dose induced some renal damage.
