An introduction of landfill tax has been recently in issue in order to raise the financial resource for establishing waste resource-circulation society. The objectives of this study are to evaluate the plan of increasing energy recovery from waste at Incheon Metropolitan City, and to propose several points to be considered in terms of introducing the landfill tax. There are a lot of problems that impede energy recovery from waste at Incheon Metropolitan City, such as high-calorific waste from decrease of food waste to the municipal incineration plant, metals and batteries in the standard plastic garbage bag, etc. Alternative policies to solve these major problems have been drawn. 본 논문은 자원순환사회 구축을 목표로 필요한 재원마련을 위해 도입예정인 폐기물부담금제에 대응하기 위한 폐기물의 에너지화 제고방안을 인천시를 중심으로 평가하고 폐기물부담금제 도입을 위해 고려하여야 할 사항들을 제안하였다. 인천시의 폐기물 에너지화를 위한 주요 문제점으로 파악된 음식물류폐기물의 반입량 감소에 따른 폐기물의 고발열량화, 종량제봉투에 혼입되어 배출되는 금속류, 건전지등을 해결하기 위한 대책을 도출하였다.

Multi-level Model Examinations of the Relationship between Family Risks and Neighborhood Settings among Delinquent Adolescents

임지영 한국청소년학회 2011 청소년학연구 Vol.18 No.1

The purpose of this study was to explore the impact of neighborhood settings on family risks that delinquent adolescents experienced. Participants included 1,086 youth who came to the attention of four county juvenile courts. The Hierarchical Linear Modeling (HLM) analyses revealed that there were significant between-neighborhood variations in family risks including family support, family conflict, tip-toeing, poor parenting, economic hardship, and transitional risk, and demonstrated that the neighborhood economic disadvantage was associated with family risks. The findings of this study contribute to the extant literature on juvenile delinquency by providing empirical support for the proposed model that illustrated the significant relationship between a neighborhood setting indicator and family risks. Implications for the prevention and intervention of delinquent adolescents are discussed.

Although there are many studies comparing the individual effects of zoledronic acid and teriparatide in bone grafting in an osteoporotic environment, the combined effect is not well known. The purpose of this study was to compare the effects of systemic administration of zoledronic acid and teriparatide on bone regeneration at the bone graft site after bone grafting to the cranium defect in rats with osteoporosis induced by ovariectomy. Thirty-nine rats were randomly divided into 8 groups (sham ovariectomy group [sOVX, n=4]; Control group [CONT, n=5]; sham zoledronic acid group [sZA, n=5]; sham teriparatide group [sTPD, n=5]; sham zoledronic acid and sham teriparatide group [sZATPD, n=5]; zoledronic acid group [ZA, n=5]; teriparatide group [TPD, n=5]; zoledronic acid and sham teriparatide group [ZA-TPD, n=5]). A critical size defect with a diameter of 5 mm was formed on both craniums of osteoporosisinduced rats, and bone grafting was performed on only one side. The defect on both sides was covered with a collagen membrane. After bone grafting, zoledronic acid and teriparatide were administered, and all animals were sacrificed 6 weeks after bone grafting. Specimens were subjected to micro-computed tomography and histological analysis. As a result of micro-computed tomography analysis, bone mineral density in the tibia was the highest in the ZA-TPD group, followed by the zoledronic acid and teriparatide groups. Residual graft material at the site where bone grafting was performed was the highest in the TPD group, and new bone increased in the order of CONT, ZA, TPD, and ZATPD groups. The TPD group had the most new bone in the area where bone grafting was not performed, and the CONT group had the biggest BS/BV, but there was no statistically significant difference. As a result of histological morphological analysis, the remaining graft material in the bone graft site decreased in the order of CONT, ZA, TPD, and ZA-TPD groups, and the new bone increased in the order of ZA, ZA-TPD, CONT, and TPD groups. The amount of new bone in the areas where bone grafting was not performed increased in the order of ZA, CONT, TPD, and ZA-TPD groups, and the CONT and TPD groups showed a statistically significant difference from the ZA-TPD group. Zoledronic acid and teriparatide showed differences in bone regeneration at the parietal bone graft site, and the combination of the two drugs was more effective in bone regeneration.

임지영 한국초등교육학회 2004 초등교육연구 Vol.17 No.1

본 연구에서는 한국판 Beck(아동용 문제행동 평가척도의 신뢰도와 타당도를 검토하였다. 초등학생 155명과 문제 아동 집단 30명을 대상으로 연구한 결과, 신뢰도와 타당도가 모두 비교적 양호하게 나타났다. 내적합치도는 a 계수가 .80 이상으로 상당히 높았다. 요인 분석을 실시한 결과 두 요인으로 구성되어 있다는 결과를 얻었고, 공격성 척도 및 비행척도와 유의미한 상관을 보임으로써 공인타당도가 확인되었다. 또한 문제행동 점수가 정상 아동 집단에 비해 문제 아동 집단에서 더 높아 척도의 준거타당도가 확인되었다. 마지막으로 본 연구가 갖는 제한정과 후속 연구에 대한 시사점을 논의 하였다. This study was conducted to examine the reliability and validity of a Korean translation of Beck Disruptive Behavior Inventory for Youth. Participants were 155 students (70 boys and 85 girls) attending elementary schools in Seoul and Kyunglu. The students were predominantly in grades 4 through 6. The comparison group for the m t study consisted of the 30 children (17 boys and 13 girls) who have received psychotherapy more than 10 times for the past 6 months due to many behavior problems. The Korean version of Beck Disruptive Behavior Inventory for Youth yielded high internal consistency reliabilities with alpha coefficients greater than .80. Results of factor analysis showed that two factors were appropriate to describe the underlying dimensions of the inventory. The first factor included the items regarding antisocial behavior or violent behavior. The second factor was related to oppositional behavior. The Korean Beck Disruptive Behavior Inventory showed significant correlations with the measures to evaluate aggressive and delinquent behavior of children. The comparison group yielded higher scores on the Beck Inventory and two other measures of conduct problem than normal students. No significant differences were found between boys and girls on all three measures included. Limitations of this study and suggestions for further study were also discussed.

음폐수 초기 pH 및 기질교체량에 따른 미생물연료전지 운전 특성 평가

임지영,김진한 한국폐기물자원순환학회 2014 한국폐기물자원순환학회 학술대회 Vol.2014 No.11

2013년 폐기물 해양배출 금지로 인하여 음폐수 육상처리가 의무화되었으며, 그로 인하여 음폐수 육상처리방안에 대한 새로운 방안들이 제시되고 있다. 음폐수와 같은 고농도의 폐수는 많은 유기물을 함유하고 있기 때문에, 이러한 유기물로부터 에너지를 회수하는 방안들이 연구되고 있으며, 그중 하나가 미생물 에너지 전환기술이다. 미생물연료전지는 혐기성 조건에서 미생물을 이용하여 유기물질을 에너지발생원으로 이용하여 전기를 생산한다. 따라서, 화학에너지를 전기에너지로 변화시키므로 별도의 오염물질을 발생시키지 않아 친환경 에너지 전환기술로 주목 받고 있다. 본 연구에서는 Single Chamber인 미생물연료전지를 이용하여 음폐수 초기 pH 및 기질교체율에 따른 미생물 연료전지의 성능에 대해 알아보기 위하여 실험을 진행하였다. 대상폐수는 수도권매립지관리공사 내 음폐수처리장 혐기성소화조 처리수(pH 7.56, SCODcr 956 mg/L)를 사용하였다. 산화전극과 환원적극으로 각각 Graphite felt, Carbon cloth를 사용하였으며, 분리막은 Ceramic막을 사용하였고, 외부저항 1,000Ω, 운전온도 35℃이었다. 실험은 초기 pH를 5~9로 설정하여 batch로 진행하였으며, 그 결과 중성 조건 즉, pH 6, 7에서 전력발생량이 가장 안정적으로 발생되는 것을 확인할 수 있었다. 또한, 기질교체율을 1%, 2%, 4%, 6%, 8%, 10%의 경우로했을 경우, 10%일 때 기질교체시 충격부하에 의해 미생물연료전지의 성능이 저하되는 것을 알 수 있었다. 이를 바탕으로, 기질교체율을 충격부하의 영향을 받지 않는 1%, 2%, 4%, 6%, 8%로 설정하였고 초기 pH를 6~7로 조절하여 각 pH 별 기질교체율에 따른 미생물연료전지의 전력발생량을 비교하였다. 실험은 매일 같은 시간 기질을 교체하는 Fed-batch로 진행하였다. 음폐수 초기 pH 및 기질교체율에 따른 미생물연료전지의 성능을 비교한 결과, pH 6일 경우 기질교체율 1%, 2%, 4%, 6%, 8%에서 평균 0.552 V ~ 0.605 V의 범위를 보였으며, 최대값은 기질교체율 6%에서 나타났다. 또한 pH 7, 기질교체율 1%, 2%, 4%, 6%, 8%에서 전력발생량은 평균 0.486 V ~ 0.569 V의 범위이었으며 pH 6의 경우와 마찬가지로 기질교체율 6%에서 최대값을 나타내었다.

임지영,Yoonsil Yi,정상우,박대성 물리치료재활과학회 2018 Physical therapy rehabilitation science Vol.7 No.4

Objective: The purpose of this study was to analyze and compare vertical ground reaction forces during sit to stand (STS) and gait between female elderly and young individuals using the Wii Balance Board (WBB). Design: Cross-sectional study. Methods: Fifty-one female elderly people (age: 75.18±4.60 years), and 13 young people (age: 29.85±3.69 years) performed the five times STS test and gait respectively on the WBB. We analyzed time (s), vertical peak (%), integral summation (Int_SUM, %), and counter variables (%) in STS and 1st peak (body weight, BW%), 2nd peak (BW%), peak minimum (BW%), time (second), center of pressure (COP) path length (mm), and Int_SUM (BW%) in gait. The independent t-test was used to assess for differences in STS, gait ability, and general characteristics between the female elderly group and young adults group. With the first and last trials excluded, the mean value was obtained from the middle three of the five trials. Results: During STS, Int_SUM and time of young adults were significantly less than of the female elderly subjects. There were no significant differences in peak and counter variables. In gait, all variables (1st peak, 2nd peak, min, time, COP_path, and Int_SUM) showed significant differences between groups (p<0.05). This study demonstrated that the validity of vertical ground reaction forces occurring during STS and gait was significant in female elderly and young adults. Conclusions: Based on the measurement of vertical ground reaction forces in STS and gait using the WBB, it is possible to clinically improve the quality of geriatric physical therapy. Further studies are necessary to examine concurrent validity of elderly patients who have undergone total hip or knee replacement.

3D 가상착의 시스템에 의한 아동후기 비만여아의 슬랙스 원형 설계

임지영 복식문화학회 2015 服飾文化硏究 Vol.23 No.4

The purpose of this study was to develop slacks patterns for obese-schoolgirls aged 10~12 by using a 3D virtual garment simulation system. The criteria for subjects in this study were girls who had a BMI of over 25kg/m2. A total of 155 schoolgirls who met these criteria were enrolled. The results were as follows: First, by using 3D virtual garment simulation, a new slacks pattern considerate of obese-schoolgirls was developed. The basic numerical formulae were as follows: Front and back hip girth of H/4-0.5+1 and H/4+0.5+1.5, front waist girth of W/4+1+0.5, back waist girth of W/4+2+0.5, front crotch extension of H/16-0.5, back crotch extension of H/8-0.5, front dart amount of 1, and back dart amount of 2. Second, according to the new slacks pattern appearance evaluation, the new slacks pattern scored more highly than the existing pattern for silhouette and ease amount, confirming that the new slacks pattern is appropriate for obese-schoolgirls. Additionally, the new slacks pattern was evaluated allowing for the proper space length of the waist, abdomen and hips. This study is expected to serve as important basic data for ensuing studies that may utilize a 3D virtual garment simulation system with 2D patterns and for future 3D pattern production program development.
