任昌元 群山大學校 1982 論文集 Vol.4 No.-

Personnel administration in education is a very important area which determines educational successes or failures, recognizing that personnel administration in education involves many problems in itself. This study identified such problems. With this purpose, this study considered the personnel administration as composed of four subcategories: teacher recruitment, working conditions, pre-and in-service training and rating systems of teacher efficiency. As a result of the research, the following conclusions were made. (1) When teachers are newly employed, advantages of the teachers graduated from the national teachers' colleges over those from the private sections, should be removed. (2) The ranks and functions in the teacher's organization should be specialized in order to activate the organization and to ensure the professionality of teaching job. (3) The teachers rating scores of in-service training should be leveled up equal to the career rating scores or the rating scores of teacher efficiency, in order to increase teachers' compentence and to expand the opportunities of promotion for the competent teachers. (4) Standards of employment should be established such that those personnels of general administrative postions should be barred from taking a teaching job, and that competent teachers can take such positions as superintendents or educational specialists. (5) The teacher exchange program should be improved to make the personnel management reasonable with regards of teachers' satisfaction with their job. (6) The raising intervals of the teachers' salary should be shortend, and the same levels of salary should be maintained as compared with other kinds of occupations. (7) An improvement measure which can set the teachers free from their heavy duties should be prepared in order to provide with such conditions that teachers can be absorbed only in teaching. (8) In order to increase teacher's compentence and ensure their professionality efficient in-service education should be provided. (9) Rational and comprehensive devices for rating teachers efficiency are required, which should be reliable and objective as well. (10) In order to attract competent teachers, comprehensive improvement measures should be prepared in different areas of personnel administration in education.

任昌元 圓光大學校大學院 1981 學位論叢 Vol.6-1 No.-

The purpose of this study was to fine an improving measure for in-service education in secondary school teachers. The method employed in the study was: 1) to analyse reference books and to review theoretical background concerning the pre and in-service education in secondary school teacher. 2) to compare the systems of pre and in-service education in secondary school teachers of our country with those of other countries. 3) to analyse the present status of in-service education in seconary school teachers and to clarify problems through interview. In lines with the above research process, conclusions and results were identified as follows: 1) In-service education in secondary school teachers should be enriched to the equal level with pre-service education. 2) The various facilities for in-service education should be completely equipped and attached professor for in-service education institute should be employed. 3) In-service education program have to consider to meet such variables as individuality, each characteristics of community and teacher's need. 4) Opportunities for in-service education should be more frequently provided. 5) For the purpose of efficient in-service education, various instruction-learning materials should be developed and the process of in-service educational curriculum should be specified. 6) The curriculum of in-service education should be organized suitably in relation with individual differences of teachers. 7) In-service education program should be organized so as to cultivate higher teaching profession. 8) For the improvement of in-service education, such various teaching methods as lecture, questions, conversation, discussion, problem solving and project methods should be utilized. 9) The opportunity for in-service education should be prepared in any time and any place. 10) Evaluation of teacher's achievement must have deep validity and high reliability. 11) Teachers who completed the course of an in-service education and who take an excellent achievement should be given such incentives as higher pay, the benifits of personal management and aquisition of higher status in schools. In connection with above conclusions and results of the study, some suggestions may be summarized as follows: 1) Political interests concerning life-long education should be requested. 2) Graduate schools of educatio should be managed much more efficiently for an in-service education institute as wall as pre-service education. 3) Teacher's center attached to Korean Teachers Association should be established and managed. 4) In-service education in secondary school teachers should be devied separatedly up middle school teachers and high school ones each other.

Interval-valued data regression using nonparametric additive models

임창원 한국통계학회 2016 Journal of the Korean Statistical Society Vol.45 No.3

Interval-valued data are observed as ranges instead of single values and frequently appear with advanced technologies in current data collection processes. Regression analysis of interval-valued data has been studied in the literature, but mostly focused on parametric linear regression models. In this paper, we study interval-valued data regression based on nonparametric additive models. By employing one of the current methods based on linear regression, we propose a nonparametric additive approach to properly analyze intervalvalued data with a possibly nonlinear pattern. We demonstrate the proposed approach using a simulation study and a real data example, and also compare its performance with those of existing methods.

임창원,박세창,허강준,Im, Chang-Won,Park, Se-Chang,Heo, Gang-Joon 대한수의학회 2006 大韓獸醫學會誌 Vol.46 No.3

To determine the effects of exposure to formalin on the secondary stress indices, changes in haematology and blood chemistry were monitored in healthy crucian carps (Carassius auratus). Fishes were separately exposed in a concentration range of 125 to 500 ppm formalin for 60 min. After exposure, red blood cell (RBC) count and packed cell volume (PCV) were elevated in the 500 ppm formalin exposed group. However, mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) were decreased significantly in the 500 ppm formalin exposed group. Total protein, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, total bilirubin, inorganic phosphorus (IP) and magnesium were significantly increased at a concentration of 500 ppm. Alkaline phosphatase (ALP) and glucose were increased at a concentration of 500 ppm, but this was not significant. Lactate dehydrogenase (LDH) and calcium were significantly decreased at concentrations of 250 and 500 ppm. AST, ALT, glucose and magnesium were significantly increased in the 250 ppm formalin exposed group. These results suggests that formalin exposure might cause some damage in the liver and kidney of crucian carp.

The abnormal meat could caused by abscess, fibrosis and granuloma in the region of the neck by adverse effect of vaccination or antibiotic injection under swine practice. In this study, the incidence of abnormal meat due to antibiotics injection was investigated using marbofloxacin from different manufacturers. To evaluate the incidence of abnormal meat via antibiotic treatment, a total of 440 pigs with the age of 140~150 days old were selected. Two hundred of pigs were assigned as a control group and 2 mL of saline was inoculated daily for three days. Two hundred forty of pigs were used as treatment group and further divided into 6 groups, consisting of 16% of original marbofloxacin treated, 10% of original marbofloxacin treated and 4 different kinds of generic marbofloxacin treated groups respectively. When test animals were slaughtered, incidence, type and size of induced abnormal meat were recorded. In the result of this study, statistical analysis found significantly lower incidence of abnormal meat formation was in 16% original marbofloxacin treated groups compared to the other tested groups (P<0.05). In the summary, antibiotic treatment could produce abnormal meat formation but the 16% of original marbofloxacin had the most minimal abnormal meat formation effect.

서로 다른 연소속도를 가지는 추진제를 적용하여 연료유량을 조절하는 고정노즐형 덕티드램제트 추진기관의 사거리 증대를 위한 사전 연구를 수행하였다. 현 설계영역에서는 빠르게 가속할 수 있는 높은 연료유량을 적용하여 높은 발사고각으로 발사할 수록 사거리가 증가하며, 흡입 공기유량이 적은 고고도에서는 연소효율을 높이기 위해 저속연소 추진제로 전환하는 것이 유리한 것으로 나타났다. 그러나 연료유량과 발사고각은 안정적인 흡입구 동작에 의해 제한되므로 적절한 마진을 확보하는 것이 필요하다.

크기가 1인 표본들로 구성된 집단에 기반한 모평균의 차이를 검정하기 위한 최소 조합 t-검정 방법

허미영,임창원,Heo, Miyoung,Lim, Changwon 한국통계학회 2017 응용통계연구 Vol.30 No.2

일반적으로 각 N개의 모집단에서 2개 이상의 표본이 추출되었을 때, $H_0:{\mu}_1={\cdots}={\mu}_N$의 가설에 대하여 검정할 수 있지만 각 모집단으로부터 표본이 한 개씩 추출된다면 ${\bar{X}}$가 존재하지 않으므로 모평균의 차이 검정은 불가능하다. 하지만 하나씩 추출된 표본으로 구성된 집단을 두 집단으로 나누어 임의의 평균을 생성함으로써 평균의 차이를 비교한다면 표본들 사이에 존재할 수 있는 이질성을 파악할 수 있다. 따라서 우리는 두 집단으로 나눌 수 있는 조합의 수만큼 평균 차이를 검정할 수 있는 최소 조합 t-검정 방법을 제안하고자 한다. 최종적으로 본 논문에서는 한 개씩 추출된 표본들 사이의 이질성을 확인하기 위하여 평균 차이를 검정할 수 있는 방법을 제안하였고 모의실험 연구를 통해 성능을 확인하였고 실제 자료 분석을 통해 결과를 도출하였다. It is often possible to test for differences in population means when two or more samples are extracted from each N population. However, it is not possible to test for the mean difference if one sample is extracted from each population since a sample mean does not exist. But, by dividing a group of samples extracted one by one into two groups and generating a sample mean, we can identify a heterogeneity that may exist within the group by comparing the differences of the groups' mean. Therefore, we propose a minimum combination t-test method that can test the mean difference by the number of combinations that can be divided into two groups. In this paper, we proposed a method to test differences between means to check heterogeneity in a group of extracted samples. We verified the performance of the method by simulation study and obtained the results through real data analysis.
