The droplet behavior of 83.9 wt.% HAN water solution was investigated experimentally with various ambient temperature and nitrogen environment. At the initial stage of evaporation under thermal decomposition temperature of HAN, gradual decreasing of droplet diameter was observed. After that, the droplet started to expand due to the internal pressure build up by water nucleation inside the droplet. The micro explosion was observed at higher temperature than the decomposition temperature of HAN and the remaining droplet showed similar behavior of single composition droplet. The decreasing rate was augmented as the ambient temperature increasing.

Background : This study was performed to determine the cut-off value and the predictability of symptomatic human cytomegalovirus (HCMV) infection according to the peak value of HCMV antigenemia assay in kidney transplant recipients. Materials and Methods : We reviewed the results of HCMV antigenemia assay (Chemicon, CA, USA) in patients who received kidney transplantation at our institution from May 2003 through May 2008, and investigated the existence and the type of HCMV infection by the medical record review. Patients who underwent the test only once during the episode or those who received ganciclovir for more than 48hrs before the test were excluded. The receiver-operator characteristic curve was drawn and the point showing maximum likelihood ratio (LR) was chosen as the cut-off value of symptomatic HCMV infection. Results : A total of 689 episodes were screened and 134 episodes were enrolled. Thirty-three (24.6%) episodes were symptomatic HCMV infection, 23 (17.2%) episodes were associated with HCMV syndrome, and 10 (7.5%) episodes were tissue-invasive diseases. The maximum LR was 7.5 (95% confidence interval, 4.014.2) and the cut-off value was 29.5 cells/200,000 WBC. The sensitivity, specificity, Positive predictive value, and negative predictive value were 66.7%, 91.1%, 71.0%, and 89.3%, respectively. Conclusions : The cut-off value of symptomatic HCMV infection by the peak value of HCMV antigenemia assay in our study was similar with previous results, although the sensitivity was relatively low.

김포시와 고양시 일대의 한강하구 지역은 우리나라에서 재두루미의 가장 중요한 월동지 및 중간기착지로 알려져 있지만, 이 지역의 조류 서식환경은 심각한 개발압력과 인간의 간섭으로 인해 지속적으로 나빠지고 있다. 따라서 본 연구에서는 2007-2008년과 2011-2012년의 월동시기에 본 지역에 도래하는 재두루미를 대상으로 월동 개체군 크기 변화와 월동지역 내에서 과거와 현재의 취식지역 이용 현황 등을 조사하여 개발행위가 이들의 서식에 미치는 영향을 확인하였다. 본 지역에서 월동하는 재두루미 개체군은 평균 124.9개체(2007-2008년)에서 59.0개체(2011-2012년)로 감소하였으며, 주요 취식지역에서 확인된 개체수는 평균 77.7개체에서 24.1개체로 감소하여 월동개체군의 감소폭에 비해 주요 취식지역의 이용 개체수의 감소폭이 더 크게 나타났다. 유형별 분석에서는 가족군에 비해 무리군의 개체수가 많이 감소한 것으로 나타났으나, 홍도평 지역의 가족군 이용 개체수는 변화가 나타나지 않았다(Mann-Whitney test. Z=-0.26, p=0.979). 그리고 과거 다수의 재두루미가 주요 취식지역으로 이용하였던 송포동과 평동지역은 2012-2013년 조사에서는 거의 이용하지 않는 것으로 나타났다. 이는 위 지역의 개발행위(예: 제 2자유로 건설 등)와 깊은 연관성이 있는 것으로 생각된다. Han-river estuary in Gimpo and Goyang city is well known as one of the most important wintering and stopover sites for migrating White-naped Crane (Grus vipio) in Korea. Nowadays, habitat quality of this area is getting worse due to serious development pressure and high human disturbances. So, we wanted to know whether development actions affected total wintering population change in Han-river estuary and feeding group pattern of White-naped Crane in main feeding habitats between the 2007-2008 and 2011-2012 wintering period. Average wintering population was decreased 124.9 to 59.0 and population of main feeding site also decreased 77.7 to 24.1. But decrease rate of main feeding site population was higher than total wintering population. Non-family feeding population was more decrease than family feeding population in the flock type analysis. But family feeding population of Hongdopyong was maintained from past and present (Mann-Whitney test. Z=-0.26, p=0.979). However, almost all White-naped Crane din not use both feeding sites, Pyong-dong and Songpo-dong, where were deteriorated habitat quality by human act.

목적: 본 연구의 목적은 발달장애 아동에게 그룹 감각통합치료를 적용하여 아동의 운동기능 및 사회성 증진에 어떠한 영향을 미치는지 알아보고자 한다. 연구방법: 대전 S아동연구소 감각통합치료실을 이용하는 아동 중, 발달장애 및 정신지체로 진단받은 아동 10명을 대상으로 하였다. 실험군은 그룹 감각통합치료에 참여하는 아동 5명, 대조군은 개별 감각통합치료에 참여하는 아동 5명으로 주 1회 90분, 20주 동안 적용하였다. 아동의 운동기능 및 사회성 증진 정도를 측정하기 위한 사전·사후 검사로 운동적합성 검사(Bruini nks-Oseretsky test of Motor Proficiency 2), 한국판 적응행동검사(Korean-Scales of Independent BehaviorRevised) 그리고 사회성숙도 검사(Social Maturity Scale)를 사용하였다 . 결과: 그룹 감각통합치료 적용 전·후 실험군 대부분의 아동이 손/상지협응(Manual coordination)과 신체협응(Body coordination), 사회성 전반적 영역에서 기능향상을 보였지만, 통계적으로 유의미하지 않았다. 그러나 그룹 감각통합치료 프로그램 전후 운동기능 및 사회성 향상의 차이는 실험군 아동이 대조군 아동보다 더 크게 나타났으며 특히 손/상지협응(Manual coordination), 손기민성(Manual dexterity) 하위항목, 사회성숙도 검사의 사회연령, 사회지수에서 통계적으로 유의미하게 나타났다. 결론: 본 연구결과를 통하여 그룹 감각통합치료 프로그램이 발달장애 아동의 운동기능 및 사회성 기능증진에 효과가 있음을 알 수 있었다. 추후 보다 다양한 장애 유형의 아동을 대상으로 그룹 감각통합치료 프로그램을 적용하여 그 효과를 증명하는 연구가 진행되어야 할 것이다. Objective : The purpose of this study is to understand whether group Sensory Integration(SI) therapy has the effect on improvement of motor skill and social function for children with developmental disorder. Method : The subjects were recruited among children received sensory integration therapy at a Children’s Development Institute in Dae-Jeon, experimental group is total 5 participating in group sensory integration therapy and control group is also 5 participating in individual sensory integration therapy. The program was constructed for 90 minutes and all children either in the experimental or in the control group went through intervention for 20 weeks. Bruininks-Oseretsky test of Motor Proficiency II, Korean-Scales of Independent Behavior-Revised and Social Maturity Scale were used in order to evaluate the degree of improvement in motor skill and social function. Results : Most children in the experimental group showed improvement in overall aspects of motor skill and the social function comparing pre-intervention with post-intervention, but they did not show any statistically significant differences. However, comparing experimental group with control group, children in the experimental group showed improvement in motor skill and social function. Futhermore, there is statistically significant improvement especially in manual coordination, manual dexterity, and social age and social quotient in Behavior-Revised and Social Maturity Scale. Conclusions : It is found that a group Sensory Integration therapy program has effect on motor skill and social function for children with developmental disorder in this study. In the future study, group SI therapy should be applied for children with diverse diagnosis in order to generalize the effectiveness of therapy.

The kinetics of the complex formation have been studied for the diethylenetriamine (dien) complexes of [PtCl₄]^(2-) in aqueous solution. [PtCl₄]^(2-) reacts with diethylenetriamine at a measurable rate with the conventional method and the rate equation for the reaction is expressed d [Pt(dien)Cl+] /dt= {k₁, [H+]+ k₂ [H+]^(-1)] [dien] [PtCl^(2-)_(4)}. A mechanism involving preliminary association of diethylenetriamine with [PtCl₄]^(2-) is proposed.

As industrialization and dramatic economic advancement have been progressed in Korea, the number of vehicles and corresponding number of traffic accidents have been increased in Korea. Traffic accidents may lead to serious problems to the family and society as well as to the victims. Literature review revealed that there has been little research on this topic in Korea. Thus, the present study was designed to explore the relations between stress and adaptation among patients with traffic accidents. In order to accomplish this purpose, two independent studies were conducted. More specifically, Study 1 utilized open questionnaire with 102 traffic accidents patients residing in Taegu and Kyongsangbuk-do area, focusing on their life stresses and coping styles. Thus, future study needs to explore the relations among stress, coping, and adaptation in the same study.
