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.

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.

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.

IFRS17에서 계리적 추정의 개선방안: 단기납 종신보험의 해지율 가정을 중심으로

임창원,이항석,김선애 한국보험학회 2024 保險學會誌 Vol.139 No.-

IFRS17 기준서에 따르면 보험계약을 평가할 때 발생할 수 있는 모든 정보를 포함하여야 하며 평가일 현재의 이용 가능한 모든 정보를 반영하도록 하고 있다. 따라서 손해율, 해지율 등의 계리적 가정과 보험계약자가 보험기간 중 선택할 수 있는 계약자 행동가정이 필요하다. 따라서 본 연구에서는 저해지형 단기납 종신보험 상품의 계약자 행동에 따른 해지율의 변화가 보험사의 수익성 지표인 CSM에 미치는 영향을 살펴보고자 한다. 7년납 종신보험을 예시로 저해지형 단기납 종신보험 상품의 현금 흐름과 현금 흐름에 따른 계약자의 행동양상을 추정하였다. 먼저 7년납 종신보험 상품은 보험료 납입이 완료되는 7년 후에 보험료 대비 환급률이 100%에 근접하고, 여기에 추가적으로 장기유지보너스가 추가 지급되어 수익률이 124%가 되는 상품으로 설계하여 7차년도와 10차년도에 해지 가능성이 높아진다. 이에 해지율 가정을 공격적, 산업평균, 계리실무 기준으로 나누어 분석한 결과 해지율을 낮게 설정할수록 CSM감소와 이에 따른 보험회사의 수익률에 영향을 미친다. According to IFRS17, the valuation of an insurance contract should include all information that is relevant and reflect all available information at the valuation date. Therefore, actuarial assumptions such as loss rates, surrender rates, and policyholder behavior assumptions that policyholders can choose during the policy period are required. Therefore, this study aims to examine the impact of changes in surrender rate due to policyholder behavior on CSM, an insurer’s profitability indicator, for a low-surrender, short-term whole life insurance product. Using 7-year whole life insurance as an example, we estimate the cash flows of low surrender rate short-term whole life insurance products and the behavior of policyholders according to the cash flows. First, the 7-year whole life insurance product is designed with a return to premium ratio close to 100% after 7 years of premium payments and an additional long-term retention bonus, resulting in a return of 124%, which increases the likelihood of surrender in the 7th and 10th years. We analyzed the lapse rate assumptions by aggressive, industry average, and actuarial practice, and found that lower lapse rates reduce CSM and impact the insurer’s profitability.

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.
