Papillary immature metaplasia (PIM) of the uterine cervix (Immature condyloma) is a subset of low grade squamous intraepithelial lesion (LSIL) which is frequently associated with human papilloma virus (HPV) types 6 and 11. The histologic features of PIM include filiform papillae lined by evenly spaced immature metaplastic-type cells with frequent nucleoli, mild anisokaryosis, and a low mitotic index. To characterize the cytologic changes associated with PIM, we analyzed 14 cases of PIM from our file. We reviewed biopsy slides and the cervicovaginal smears taken proximate to the time of blopsy. Histologically, nine cases had either flat condyloma (7 cases) or high grade squamous intraepithelial lesion (HSIL) (2 cases). Cytologic changes included cells in various stages of maturation with karyomegaly (14 cases), cells with irregularities in the nuclear membrane (13 cases), intermediate cells with karyomegaly(13 cases), cells with binucleatlon (13 cases), and aborted koliocytes (11 cases) Cervicovaginal smears from all cases were interpreted as atypical squamous cells of undetermined significance (ASCUS), NOS or ASCUS, rule out squamous intraepithelial lesion (SIL) or LSIL in two cases with flat condyloma or HSIL in a case with severe dysplasia. PIM is a distinct histologic entity that can present with a spectrum of cytologic findings, but cytologic findings may resemble variable reactive conditions and immature HSIL. Therefore, it is difficult to diagnose PIM by cytology alone. However, the meticulous efforts for making the cytologic diagnoses which can Induce active management of patients are recommended because PIM is a variant of LSIL and frequently has a flat condyloma or HSIL.

The purpose of this study is to describe the cellular characteristics of endometrial hyperplasia without/with atypia in cervical smears. These cellular features were compared with those of normal endometrium and endometrial carcinoma. We reviewed 265 cervical smears : 64 normal proliferative endometrium, 118 endometrial hyperplasia without atypia, 21 endometrial hyperplasia with atypia, and 62 endometrial adenocarcinoma. Of these smears, 72(27.2%) smears which had diagnostic endometrial epithelial cells were selected for this study. The cytologic abnormalities about cellularity, background, changes in cellular architecture, alterations in nuclear size, anisokaryosis, chromatin pattern, nucleoli, cytoplasmic vacuoles, and mitosis were observed. Nuclear enlargement(1.6 to 2 times of the nucleus in the intermediate squamous cell) and anisokaryosis(${\geq}$2 fold in size variation) were highly suggestive of endometrial hyperplasia without/with atypia. The nuclei from endometrial hyperplasia with atypia were more coarsely granular in chromatin patterns than hyperplasia without atypia(33.3% vs 3.4%). Micronucleoli were observed in all endometrial conditions, but the presence of macronucleoli were more suggestive of hyperplasia with atypia(22.2%) and adenocarcinoma(55%). The changes in cellular architecture(loss of polarity, uneven internuclear distance, overlapping and loose arrangement) were seen in hyperplasia with atypia and adenocarcinoma. Characteristically, bloody background was seen in endometrial hyperpiasia, and cellular detritus or granular proteinaceous material was only observed in endometrial adenocarcinoma. Mitoses were also observed in adenocarcinoma. In conclusion, although there is no single parameter useful for the cytologic differential diagnosis of endometrial lesions, combined cytologic evaluation can be used to diagnose hyperplasia cytologically.

본 연구는 공을 활용한 신체활동 프로그램이 유아의 실행기능(억제, 인지유연성, 작업기억)에 미치는 효과를 알아보는데 목적이 있다. 본 연구는 만 5세 유아 34명(실험집단 17명, 비교집단 17명)을 대상으로 실시하였으며 2017년 10월 27일부터 12월 7일까지 총 6주간에 걸쳐 사전검사, 실험처치, 사후검사 순으로 이루어졌다. 공을 활용한 신체활동 프로그램은 Pica(2013)와 Gallahue & Ozmun(2009)의 이론과 체계를 기초로 구성하였다. 사전·사후검사 결과는 공분산분석(ANCOVA)을 통해 분석하였다. 분석결과 공을 활용한 신체활동 프로그램은 유아의 실행기능에 긍정적인 영향을 미치는 것으로 나타났다. 이러한 효과는 인지억제, 행동억제, 인지유연성, 작업기억을 포함하는 모든 하위영역에서 공통적으로 나타났으며 공을 활용한 신체활동이 유아의 실행기능 향상에 효과적임을 보여준다. 이러한 결과를 기초로 가정과 교육현장에서 유아들이 다양한 신체활동에 참여할 수 있도록 적극 지원해야 함을 논의하였다. Recent research studies have documented the impact of physical activity on synaptic stimulations and systems, and function in memory and learning. The purpose of the present study was to develop a movement program and to examine the effect of the movement activities with balls on children’s executive functions. A movement program was developed based on the theoretical foundations and frameworks of Pica(2013) and Callahue & Ozmun(2009). Participants were 34 (17 experimental group; 17 control group) 5-year-old-children. After pretesting session, there were 20 movement sessions, and then a post-testing session. An Analysis of Covariance(ANCOVA) were performed after controlling for the effects of pre-test scores. The results revealed significantly greater positive gains over time in the children’s executive functions for the experimental group compared with the control group. Specifically, cognitive and behavioral inhibitory control, cognitive flexibility, working memory showed significant improvements after 20 movement sessions. Further research is needed to determine how movement activities with balls promote children’s executive functions. Teachers of early childhood education should provide children with a variety of physical activities to support children’s development.

본 연구의 목적은 상호작용 중심의 교사교육 과정에서 영유아 교사들의 탐구중심과학 활동의 이해와 실제에 대한 반성적 사고과정을 알아보는 데 있다. 본 연구에 참여한 7명의 경력 영유아 교사들은 14주 동안 생물과학, 지구과학, 물리과학 중 한 개의 영역을 선정하여 3회에 걸쳐 계열성 있게 탐구중심의 과학 활동을 계획-실행-평가 하고, 이를 동료 교사들과 토론한 뒤, 티칭 포트폴리오를 작성하였다. 연구결과, 영아 교사들은 영아를 위한 탐구중심 과학교육에 대해 새로운 이해에 도달하였다. 유아 교사들은 자신이 교사주도의 과학 활동을 하는 경향성을 발견하고 의도적으로 유아주도의 탐구중심 과학 활동을 하고자 노력하였다. 이 과정에서 교사들은 자신이 계획했던 과학 활동에서 벗어나더라도 유아에게 ‘가르칠 수 있는 순간’을 찾기 위해 노력하였으며, 영유아의 탐색과 교사의 개입 사이에 적절한 균형점을 찾아갔다. 마지막으로 영유아 교사들의 탐구중심 과학 활동에 대한 이해와 실제의 간극을 줄이고, 교사들의 반성적 사고를 촉진할 수 있도록 지원하는 방안에 대해 논의하였다. The purpose of this study is to explore early childhood teachers’ conceptualizations of inquiry-based science activities and their classroom practices during the Teaching through Interactions Professional Development process. Seven experienced teachers facilitated three sequential inquiry-based science activities in life science, earth science, and physical science. These teachers engaged with the process of video analysis, discussion, and portfolio writing during the 14-weeks. Findings suggest that early childhood teachers have reached a new understanding of inquiry-based science education for infants and toddlers. Teachers also realized that their classroom science activities tended to be teacher-led and deliberately conducted inquiry-based science activities led by children. In this process, teachers tried to find a ‘teachable moment’ for young children even if it deviated from their activity plans and also tried to find an appropriate balance between the exploration of young children and the teacher intervention. Finally, this study discussed ways to reduce the gap between early childhood teachers’ understanding and practice of inquiry-based science activities and support their reflective thinking.

On the basis of vegetation data by point quarter sampling method, the natural forest of Jirisan(Mt.) was classified into eight forest types by cluster analysis. They were Quercus mogolica forest type, Fraxinus mandshurica - Betula costata forest type, Mixed mesophytic forest type, Abies koreana forest type, Carpinus laxiflora forest type, Quercus serrata forest type, Pinus densiflora forest type, and Quercus variabilis forest type. Then, succession index was estimated for each forest type so as to evaluate succession process comparatively among forest types. The results showed that Carpinus laxiflora forest type had highest succession index of 219.7, followed by Mixed mesophytic forest type with little difference of the index of 218.3. Pinus densiflora forest type had lowest index. Succession indices were hardly correlated with species diversity indices of forest types. We presumed that the higher value of succession index a forest type had, the closer toward the climax forest. However, the estimated index was not supposed to be absolute level of successional stage, but it could play a role of comparative assessment in the position of the seral stage among forest types.

Purpose: Althoughpancreas injury is rare in abdominal trauma,it posesa challengeto the surgeon because its clinicalfeaturesare not prominentand the presence of main duct injurycannot be easily identified by imaging studies. Furthermore, severe pancreas injuries require a distal pancreatectomy or a pancreaticoduodnectomy which are associated considerable morbidity and mortality. We reviewed the clinical features of and outcomes for patients with pancreas injury. Methods: For 10 years from Jan. 2001 to Dec. 2010, thirty-four patients were diagnosedas having pancreas injury by using an explo-laparotomy. Patients successfully treated bynon-operative management were excluded. Patients were divided into early (n=18) and delayed surgery groups (n=11) based on an interval of 24hours between injury and surgery. The clinical features of and the outcomes for the patients in both groups were compared. Results: Males were more commonly injured (82.4% vs.17.6%). The mean age was 37.2 years. The injury mechanisms included vehicle accidents (62.9%, 22/34), assaults (20%, 7/34), and falls (11.4%, 3/34)). The head and neck of the pancreas was most commonly injured, followed by the body and the tail (16, 12, and 6 cases). Of the 34 patients, 26 (76.5%) patients had accompanying injuries. Grade 1 and 2 occurred in 14 (5 and 9) patients, and grade 3, 4, and 5 occurred in 20 (16, 3, and 1) patients. The early and delayed surgery groups showed no difference in surgical outcomes. Two patients with grade 3 in the early surgery group died after surgery,one due tomassive hemorrhage and the other due to septic shock. Of the five patients initially managed non-operatively,three developed peripancreatic necrosis and two developed pseudocyst. All five patients were successfully cured by surgery. Conclusion: All cases of pancreas injury in this study involved blunt injury, and accompanying injury to major vessels or the bowel was the major cause of mortality. Surgery delayed for longer than 24 hours after was not associated with adverseoutcomes.
