This study was conducted to elucidate the impact of invasive species, Micropterus salmoides and Lepomis macrochirus in Geumgyeji, Samgaji and Naejangji reservoirs of National Parks, Korea in 2020. In the Geumgyeji, 1,221 individuals of 11 species in 7 families were collected including M. salmoides (relative abundance, 96.3%) and L. macrochirus (0.3%), M. salmoides fed mainly on Rhinogobius brunneus (IRI, 37.2%), Odonata (25.6%), Megaloptera (11.6%), and M. salmoides (7.0%). In the results of Samgaji showed that 854 individuals of 10 species in 5 families were collected including M. salmoides (60.8%), and M. salmoides fed mainly on Decapoda (shrimp, 33.6%), Odonata (34.4%), R. brunneus (21.2%), and Zacco platypus (6.1%). In the Naejangji showed that 1,075 individuals of 13 species belonging to 7 families were collected including L. macrochirus (38.1%) and M. salmoides (9.5%), and L. macrochirus fed mainly on Branchiopoda (77.5%), Diptera (9.8%), Decapoda (4.0%) and M. salmoides fed mainly on R. brunneus (73.3%), Decapoda (21.2%). M. salmoides of Geumgyeji and Samgaji were apparently introduced more than a 10 years ago. The fish population declined rapidly since the introduction of M. salmoides. L. macrochirus of Naejangji was introduced more than 20 years ago, which increased its relative abundance to 40%. M. salmoides was introduced five to six years ago, and the fish species and population declined rapidly since the introduction of M. salmoides. Finally, we discussed the inhabitat status and management of M. salmoides and L. macrochirus in the National Park.

Background : To exatnine the problems intolved in writing practice of death certificates, we cotnpated the determination of underlying cause of death for wital statistics using recorded underlying cause of death in issued death statistics. Methods : We collected 688 rnortality certificates issue in year of 2,000 from 3 university hospitals. And we also collected vital statistics from ministry of statistics. The causes of death were coded by experienced medical record wpecialists. And causes of death determined at ministry of statistics for national vita statistics were mapped to causes of death recorded at each death certificates. The rate that underlying causes of death for vital statistics were derived from underlying causes of death recorded at issued death certificaties sere analysed. Results : 64.5% of underlying cause of death for could be derived from underlying cause of death recorded at issued death certificates, 8.6% derived from intermediate cause of death, and 3.9% derived from direct cause of death. In 23% of cases, underlying cause of death could not be derived using issued death certificates. The rate that underlying cause of death for vital statistics could be derived from underlying cause of death recorded at death certificates was different between 3 university hospitals. Ane the rate was also different between death certificates and postmortem certificates. We classified the causes of death using 21 major categories. The rate was different between diseases or conditions tha caused death too. Conclusion : When we examined the correctness of death certificate writing practice using abpve methods, cortectness of writing could not be told as satisfactory. There was difference in correctness of writing between hospotals, between death certificates and postmortem certificates, and between diseases and conditions that caused death. With this results, we suggested some strategy to improve the correctness of death certificate writing practice.

1989년 1월부터 1992년 12월 사이에 대장암으로 근치적 절제술을 시행받은후 추적조사가 가능한 45명의 환자를 대상 대장암조직의 Hematoxylin-Eosin염색을 통하여 apoptotic body를 광학 현미경하에서 400배율 하에서 관찰하여 암세포 100개당 평균개수를 세었으며 TUNEL 방법을 이용하여 면화학적염색을 통하여 염색정도를 판정을하여 대장암에서 아포토시스의 정도를 판정하여 다음과 같은 결과를 얻었다. Dukes병기 A 일 때 apoptotic body가 평균 1.93개, B 일 때 2.66개, C 인 경우 2.76개 였으며 분화도에 따라서는 고분화암인 경우 2.51개, 중등도분화암인 경우는 3.01개, 저분화암인 경우는 2.15개였다. 5년내 사망한 환자에서는 3.55개 였으며 5년이상 생존한 환자에서는 2.8개였다. 형태학적으로 apoptotic body의 수를 세어 아포토시스를 측정하여 예후예측인자로 사용할 수 있으리라 사료되며 아포토시스와 p53의 발현과의 관계를 보았을 때 특별한 상관관계를 발견 할 수 없어 bcl-2의 발현과 더불어 아토토시스와의 관게에 대하여 좀더 연구가 되어야 하겠다. Objectives : Apoptosis is a specific mode of cell death recognized by a characteristic pattern of morphological, biochemical, and molecular changes, There are several methods of detection of apoptosis. Morphological changes involve a characteristic pattern of chromation and cytoplasm. The landmark of apoptosis is endonucleolysis, with nuclear DNA initially degraded at the linker sections to fragments equivalent to single and multiple nucleosomes. Detection of DNA fragments is situ using the terminal deoxyribonucleotidyl transferase(TDT)-mediated dUTP-digoxigenin nick end labeling (TUNEL) assay is increasingly applied to investigate apoptosis. We studied the detection method of apoptosis morphologically and by using TUNEL assay and examined the correlation of p53 expression and apoptosis. Methods : Forty-five cases of colorectal cancer were selected. The number of apoptotic bodies was expressed as a number per 100 cancer cells. The TUNEL assay was performed with in situ Apoptag kit®. Results : The mean number of the apoptotic bodies was 2.28 in the patients who survived over 5 years after curative resection and 3.55 in the patients who died within 5 years(p=0.001). There was a relationship between the number of apoptotic bodies which were measured by morphologic study and the results which were measured by TUNEL assay. There was no relationship between p53 expression and apoptosis. Conclusion : These results suggest that the frequency of apoptotic bodies may be a prognostic factor for colorectal cancer and apoptosis could be measured by morphological study without special study.

본 연구에서는 유아특수교육교사 8명과의 심층면담과 30개의 IEP 문서 분석을 통해, 특수교육진흥법 상의 규정과 유아특수교육 추천 실제에 따른 IEP의 질적 수준을 알아보았다. 연구결과 특수학급 교사의 경우 유치원 교육과정과의 연계가 부족한 IEP를 작성하여 운영하고 있으며, 개별화교육운영위원회는 실질적으로 소집되지 못하고 있고, IEP의과정에 보호자의 참여 정도는 미미한 것으로 나타났다. 대부분의 IEP 내용은 유아의 현 수행수준에 근거한 장 · 단기 목표의 기술을 제외하고는 상당히 형식적이고 제한적이어서 IEP 운영에 도움을 주지 못하고 있는 것으로 나타났다. 그러나 특수교육진흥법 상에 규정되어 있지는 않지만 실제 현장에서는 가족지원이 다양한 방식으로 이루어지고 있으며, 다학문적 팀의 구성과 구성원들 간의 협력은 교사에 따라, 또는 기관에 따라 큰 차이가 있는 것으로 나타났다. 일반 유치원 프로그램의 일일 계획안과 IEP와의 연계, 발달적 교육과정과 유치원 교육과정과의 연계, 목표의 수정, 개별화교육운영위원회의 협력적 참여, 객관성 있는 수행 평가 면에서 유아특수교육교사들은 어려움을 나타내 보였으며, IEP 작성과 운영에 따른 문제를 해결하기 위해서는 무엇보다도 표준화된 IEP 양식 또는 구조화된 IEP와 평가준거의 예가 제시된 IEP 모델이 필요한 것으로 교사들은 제안하고 있다. Various research has identified a number of problems with individualized education program (IEP) development and implementation among schools, including a lack of adequate teacher training, poorly developed team processes, minimal coordination with general education, and failure to develop measurable goals and objectives to evaluate child achievements. The purpose of this study was to evaluate the quality levels of IEPs implemented in early childhood special education (ECSE) settings based on recommended ECSE practices and requirements of the Korean Special Education Enhancement Act. Through an in-depth focus group interview with eight ECSE teachers from eight different programs and an analysis of 30 IEPs, the study investigated: 1) how regulations on IEP development and implementation of the Special Education Enhancement Act, specifically regulations on IEP team organization and implementation, parent participation, and IEP contents, are interpreted in ECSE programs; 2) how ECSE program professionals collaborate with families and how family supports are provided; 3) how a multidisciplinary approach is put into practice and effective levels of collaboration among IEP team members; 4) ECSE teacher suggestions for solving problems with IEP development and implementation, and for improving practices. The results indicate that special education classroom teachers of regular kindergarten programs develop and implement IEPs that are irrelevant to their curricular. IEP procedural deficits were found in the area of team process. It was found that the ECSE programs lack a multidisciplinary team approach when developing and implementing IEPs. Overall, parental participation was not ensured even though regulations require IEP teams to include parental requests in IEPs and implement their signed IEPs. Key personnel such as regular early childhood education teachers and therapists were found to be absent from IEP meetings. However, differences were found among the programs in the team process. Programs specialized only for young children with disabilities demonstrated higher levels of team approaches than those of ECSE programs in special schools and regular kindergartens. In this study, limited content of IEPs were found to be developed for young children with disabilities. IEP goals and objectives analyzed in this study were shown to be generally adequate, showing that children's levels of performance information and annual goals were congruent and that measurable goals and objectives were developed. During the in-depth interview, it was learned that ECSE teachers provide support to children and families, coordinating services in the community for children with disabilities. The results of this study also show that ECSE teachers in regular kindergarten programs have difficulties in linking IEP goals with their daily instructional plans as well as linking their general curriculum with developmental goals for young children with disabilities. Overall, teachers in this study demonstrated difficulties with modification of IEP goals, facilitating collaborative IEP team participation, and objective monitoring of IEP goals. They suggest that standards for IEP and structured IEP forms be developed. They also suggest that model IEPs be introduced by school districts. The findings of this study suggest that: 1) specific IEP procedures need to be mandated through special education laws and regulations in order to facilitate and monitor team approaches when developing and implementing IEPs in ECSE settings; 2) a coordinated service system is needed to provide comprehensive services to young children with special needs and their families; 3) there is an urgent need for comprehensive curriculum-based assessment tools that reflect various developmental aspects as well as diverse special needs and suggest assessment guidelines; 4) it is important to provide strong pre-service teacher education programs as well as in-service work shops for teachers in order to develope skills in developing meaningful IEP goals and objectives linked to curriculum and daily classroom routines; and 5) IEP model development research should be facilitated.
