본 연구는 그동안 수행되었던 아동학대에 영향을 미치는 가족요인 연구를 종합한다는 의미에서 1987년부터 2011년까지 국내 학술지에 게재된 41편의 연구를 대상으로 보호요인과 위험요인에 관한 메타분석을 실시하였다. 분석결과, 41편의 연구에서 보호요인 40개, 위험요인 452개로 총 492개의 요인을 추출하였다. 가족영역의 보호요인과 위험요인은 아동학대와 관련이 있으며, 보호요인 보다 위험요인이 더 밀접한 관련성을 갖는 것으로 확인되었다. 가족응집력은 아동학대를 예방할 수 있는 보호요인으로 확인되었으며, 부모성별(부)은 아동학대를 유발할 수 있는 가장 평균 효과크기가 큰 위험요인으로 확인되었다. 아동학대에 영향을 미치는 가족영역의 위험요인 중 경제수준, 결손가정, 부모음주는 기존연구와 달리 아주 낮은 평균 효과크기를 보였다. 학대유형별 우선순위를 분석한 결과, 학대유형별로 보호요인과 위험요인의 우선순위에 차이가 있을 것으로 예상했으나 성학대를 제외하고는 큰 차이를 보이지 않았다. 마지막으로 아동학대에 영향을 미치는 가족영역의 보호요인과 위험요인, 학대유형별 우선순위에 따른 사회복 지실천적 함의를 논의하였다. Child abuse remains a serious social problem worldwide. The majority of the perpetrators of child abuse were parents in the family. The objective of this meta-analysis was to summarize the evidence related to the association of child abuse with protective and risk factors in the family domain. This study attempted meta-analysis by using 41 research articles on child abuse that were conducted from 1987 to 2011. The result of analysis showed that protective and risk factors in the family domain were related to child abuse; and risk factors had much more relations with child abuse than protective factors. Family cohesion was the most important protective factor that can prevent child abuse and parent`s gender(father) was identified as the most important risk factor that can lead to child abuse. We expected a huge difference in priorities depending upon types of child abuse but except sexual abuse, there were quite a little differences in priorities of protective and risk factors. In addition, the economic status, broken family, and parental drinking among risk factors showed very small effect sizes, that were different with previous studies. Finally, the implications for preventing child abuse and suggestions for the future study were discussed.

재배기간에 따른 고구마 전분의 특성을 구명하여 고구마의 새로운 식품산업 소재로서 활용방안을 모색하기 위한 기초자료로 이용하고자 실험한 결과는 다음과 같다. 재배기간이 길어질수록 전분 함량은 증가하였으나 아밀로스 함량은 감소하는 경향이었고, 일반고구마와 유색고구마의 전분함량 변화 양상에는 차이가 있었다. 재배기간이 길어질수록 전분의 수분함량 변화 양상은 일정한 경향을 보이지 않았으나 단백질과 회분 함량은 증가하는 경향이었다. 신속점도측정기로 측정한 점도는 재배기간이 길어질수록 전분의 호화개시온도와 최고점도, breakdown, setback은 증가하였고 최소 및 최종점도는 감소하였다. 주사시차열량계를 이용한 호화특성은 재배기간이 길어질수록 To, Tp는 증가하였으나 Tc, ΔT, ΔH는 일정한 변화 양상을 보이지 않았다. X-선 굴절률은 일반고구마의 회절각도는 15.08-15.32°, 16.92-17.72°, 22.90-23.62°, ‘신자미’ 15.26-15.34°, 17.08-17.32°, 22.74-23.40°, ‘주황미’ 14.98-15.32°, 17.00-17.38°, 22.82-23.40°에서 강한 피크를 보여 전분의 결정화도 형태 중 C형에 속하였으며 재배기간에 상관없이 고구마 전분의 결정화도는 일정하였다. 고구마 전분의 입자 형태는 재배기간에 상관없이 대부분 둥글고 타원형 모양을 하고 있었으며 일부 다각형의 입자 형태를 포함하고 있었다. 평균입도는 주황색고구마의 평균입도가 식용 및 자색고구마보다 컸으며 재배기간이 길어질수록 고구마 전분의 평균입도는 증가하였다. This study was performed to understand the effect of cultivation periods on the physicochemical characteristics of the starch of five sweetpotato cultivars, cultivated in Muan, Korea. Starch, protein, and ash contents increased with increased cultivation period, whereas amylose content decreased. Rapid viscosity analysis showed that the pasting temperature, peak viscosity, breakdown, setback and final viscosity increased with increased cultivation period. However, trough and final viscosity decreased. Although the onset temperature and peak temperature values increased, the conclusion temperature did not show any consistent patterns by differential scanning calorimetry. X-ray diffraction showed that the starch samples had C-type crystallinity irrespective of the cultivation period and cultivar. The starch granules were dominantly round and oval, or polygonal irrespective the cultivation period. The bigger the particle size was, the longer the cultivation period was.
