김유리,우남칠,이상덕,홍태경,김준,Kim, Yu-Lee,Woo, Nam-C.,Lee, Sang-Duck,Hong, Tae-Kyung,Kim, Joon 한국지하수토양환경학회 2008 지하수토양환경 Vol.13 No.1

광릉 수문연구부지 내 원두부 소유역에서 천부 관측정 G1, G4를 대상으로 2006년 2월부터 10월까지 5분 간격으로 관측한 지하수위 변동자료에 대한 주기적 변동원인과 그 영향을 분석하였다. 지하수위는 일주기의 반복성을 보이며, 겨울에서 여름으로 갈수록 변동폭이 증가하였다. 지하수위 관측 자료의 파워스펙트럼 분석 결과, 24.38시간의 일주기 성분과 12.19시간의 반일주기 성분이 나타나며, 이는 각각 지구 조석 성분 중 $P_1$ 분조와 $L_2$ 분조에 근접하다. 일주기 성분은 겨울에 비해 여름에 더 큰 power를 나타내어 지하수위가 조석 뿐 아니라 증발산에 의한 영향까지 함께 받고 있음을 보여준다. 또한 강우 직후의 지하수위 자료에서는 일주기 성분이 감소하는 현상 역시 일주기 성분에 증발산이 큰 영향을 미치고 있음을 지시한다. 조석과 증발산에 의한 지하수위 변동은 일주기 성분이 $0.4{\sim}4.2$ cm, 반일주기 성분은 $0.2{\sim}0.7$ cm 정도의 영향을 미친다. Periodic fluctuation of water levels were analyzed for their causes and effects on groundwater movement. Groundwater levels were monitored from two shallow monitoring wells, G1 and G4, located at a headwater catchment in the Gwangneung Ecohydrological Research Site using pressure transducers with automatic data-loggers by five-minute interval from February to October, 2006. The water table fluctuates on a daily basis with a clear diurnal variation, and the fluctuation amplitude increases with time from the winter to the summer. Results from spectral analysis of water-level data show periodic variations in 24.38 hour and in 12.19 hour, indicating $P_1$ diurnal and $L_2$ semidiurnal tidal components, respectively. The diurnal component of the water level in summer has greater power than that in winter, implying that the water table is affected not only by earth tides, but also by evapotranspiration. Right after rain stops, the power of diurnal component of the water level decreases, indicating that evapotranspiration influences significantly diurnal periodicity. The effects of diurnal and semidiurnal components of the water level range from 0.4 to 4.2 cm and from 0.2 to 0.7 cm, respectively.

Statement of problem: Currently, there are some 20 different geometric variations in implant/abutment interface available. The geometry is important because it is one of the primary determinants of joint strength, joint stability, locational and rotational stability. Purpose: As the effects of the various implant-abutment connections and the prosthesis height variation on stress distribution are not yet examined this study is to focus on the different types of implant-abutment connection and the prosthesis height using three dimensional finite element analysis. Material and method. The models were constructed with ITI, 3i TG, Bicon, Frialit-2 fixtures and solid abutment, TG post, Bicon post, EstheticBase abutment respectively. And the super structures were constructed as mandibular second premolar shapes with 8.5 mm, 11 mm, 13.5 mm of crown height. In each model, 244 N of vertical load and 244 N of $30^{\circ}$ oblique load were placed on the central pit of an occlusal surface. von Mises stresses were recorded and compared in the crowns, abutments, fixtures. Results: 1. Under the oblique loading, von Mises stresses were larger in the crown, abutment, fixture compared to the vertical loading condition. 2. The stresses were increased proportionally to the crown height under oblique loading but showed little differences with three different crown heights under vertical loading. 3. In the crown, the highest stress areas were loading points under vertical loading, and the finish lines under oblique loading. 4. Under the oblique loading, the higher stresses were located in the fixture/abutment interface of the Bicon and Frialit-2 systems compared to the ITI and TG systems. Conclusions: The stress distribution patterns of each implant-abutment system had difference among them and adequate crown height/implant ratio was important to reduce the stresses around the implants.

Transitional implants were developed to support provisional restorations and to allow for load-free osseointegration of conventional implants while a patient was provided with immediate esthetics and function and are usually placed simultaneously at the time of definitive implant placement. Transitional implants are placed in a non-submerged fashion in a single-stage surgery and are designed to be immediately loaded. They generally are made of commercially pure titanium or titanium alloy and are designed as 1-piece implants composed of root and crown replacement segments. Transitional implants can be used in a wide range of indications, such as basic use as temporary implant, to support and protect the primary implants during the healing phase, single crown in the edentulous anterior region of mandibular, anchorage for orthodontic treatment, support a surgical and radiographic template, and primary implant to extremely atrophied alveolar crests of the mandible and maxilla. This article describes the clinical use of transitional implants to support the provisional complete denture and single crown in the restricted edenturous central incisor region of mandible.

연구목적: 본 연구는 자폐성장애 아동의 식행동 중재에 관한 선행연구를 분석하고, 이를 토대로 자폐성장애 아동의 건강한 식생활을 위한 중재 개발 및 향후 과제에 주는 시사점을 살펴보는 것을 목적으로 하였다. 연구방법: 본 연구의 분석을 위해 2011년부터 2020년 8월까지 출판된 총 34편(국내 4편, 국외 30편)의 논문을 선정하였으며, 선정된 논문의 전반적 연구 동향과 식행동중재 프로그램의 특성을 고찰하였다. 연구결과: 국외연구에 비해 국내연구는 편수가 상대적으로 적었고, 일부 식행동 문제에 중점을 둔 중재 연구가 이루어지고 있었다. 대부분의 연구는 중재효과를 평가하기 위해 단일대상연구를 주로 사용하였으며, 관찰을 통해 목표행동의 변화를 측정하였다. 식행동 중재 요소로는 강화와 촉진이 가장 빈번하게 사용되었으나, 대부분의 연구에서 다양한 중재 요소가 복합적으로 사용되었다. 중재는 주로 치료사 및 행동분석전문가에 의해 이루어졌으며 가정과 치료실에서 실시되었다. 결론: 본 연구의 분석결과를 바탕으로 ASD 아동의 식행동 중재 관련 교육적 실제와 후속 연구에 주는 시사점이 논의되었다. Purpose: This study reviewed the literatures on interventions of eating behaviors of children with autism spectrum disorders, and to provide implications for future research. Method: 34 studies published between 2011 and 2020 were included for the review, of which 4 were Korean studies and 30 international studies. The studies were analyzed in terms of research trend and intervention characteristics. Results: The number of Korean studies was relatively small and the studies put an emphasis on interventions for the limited type of atypical eating behaviors compared to the international studies. The majority of studies used single-case research designs and collected observation data to evaluate intervention outcomes. Although the most frequently used intervention components were reinforcement and prompting, a number of studies employed different intervention components together. Overall, intervention was implemented by therapists and behavior analysts in the home and clinic settings. Conclusion: Based on the findings, practical implications and directions for future research were discussed.

N/A To investigate the etiopathogenic factors in the development of posttransplant diabetes, we reiviewed 163 kidney transplant patients among whom 16 patients developed diabetes after transplantation. The results were of follows: 1) Patients who developed posttransplant diabetes were 16 cases (9.8%). 2) Patients whose fasting blood sugar levels were more than 121mg% and less than 140mg% before transplantation were 35 cases (21.4%) and the prevalence of posttransplant diabetes (22.8%) in this group was higher than that (6.2%) in patients whose fasting blood sugar levels were less than 121mg% before transplantation. 3) Posttransplant diabetic patients, usually under-weight and in a nutritionally deprived state, developed diabetes in a relatively short period after transplantation with high blood sugar levels while some patients devleoped diabetes more than 1 year after transplantation with marked weight gain. 4) The mean age of patients at transplantation and the phenotype frequency of HLA-B15 antigen were higher in patients who developed posttransplant diabetes than in patients who did not, but there was no difference in the number of rejection episodes and kinds of immunsuppressants. It might be suggested that the preperative state of glucose tolerance associated with the nutritional state of patients receiving kidney transplantation could have a permissive role when various factors interact in the development of posttransplant diabetes.
