The purpose of this study was to use as a basic data to develop suitable nursing intervention program and decide an appropriate intervention time after assessing shoulder range of motion in postmastectomy from 2 weeks to 3 month. 147 patients are chosen as study subject among patients who were in recovery of 2weeks, 1month, 2months and 3 months after surgical operation which is modified radical mastectomy. Data were collected at oncology medicine local and general surgery local in Seoul National University Hospital from May, 2003 to October, 2003. The range of motion of the shoulder(flexion, extension, abduction, internal rotation, external rotation) were examined. Analysis of data that shoulder range of motion average and standard deviation, percentage of the unaffected side and affected side compare with normal shoulder range of motion. Paired t-test was adopted to analyze the difference between affected side and unaffected side. Conclusion from this study is as following, 1. The most serious problem was external rotation (0.56%) and internal rotation is the next (19.9%) in 5 kinds of shoulder range of motion in 2 weeks after surgical operation 2. There was no difference in internal rotation after post operation 3 months but there were differences and shown to recover more than 90% in flexion and abduction. Also shoulder function incresed in flextion less than 80% and more than 80% in external rotation. As this study finding was shown that shoulder range of motion did not get back perfectly except of internal rotation and extension in point of 3 months after breast cancer surgical operation. External rotation was specially shown the lowest result so it is needed to exercise for improving their physical functioning recovery in postmastectomy patients. And it is suggested to study for helping to postmastectomy patients' physical and psycosocial functions with the early rehabilitation program which is based on these results.

측량 기준점은 국민의 재산권 설정과 밀접한 연관이 있는 국가 중요시설물로 국가 또는 지자체에서 관리하고 있다. 따라서 이와 같은 측량 기준점은 측량성과는 물론 데이터베이스 및 표지의 관리에 이르기까지 중요한 국가 자료임에도 그동안 방대한 물량에 따른 인력, 시스템, 관련 제도 등 관리적 측면에서 각종 문제점들이 지속적으로 제기되어 왔다. 현재, 지자체마다 지리정보시스템이 개별적으로 구축 및 운영되고 있으나, 통합, 연계 및 활용 측면에서는 미흡한 실정이다. 따라서 본 연구에서는 지리정보시스템을 기반으로 한 측량 기준점 관련 정보 제공 및 관리를 위한 관리시스템의 기능 개선 방안과 기준점 이전 경비의 선납부제도 정착방안을 제시하였다. 이를 통해 관리자와 사용자 중심의 One-stop 기준점 관리 통합 시스템 구축의 근간을 마련하고, 기준점 망실 원인자 불명에 따른 기준점 복구비 부과 문제를 해결할 수 있을 것이다.

Fluorescence recovery after photobleaching (FRAP) is a well-established method commonly used to measure the diffusion of fluorescent solutes and biomolecules in living cells or tissues. Here a fiber-optic-based FRAP (f-FRAP) system was developed, and validated using macromolecules in water and agarose gels of different concentrations. We applied f-FRAP to measure the site-specific diffusion of fluorescein (NaFluo) in peritoneal membranes (PMs) on the liver, cecum, and kidney of a living rat during peritoneal dialysis. Diffusion of fluorescein in PM varied in a time-dependent manner according to the type of organ ($D_{PM\;on\;Liver}/D_{NaFluo}=0.199{\pm}0.085$, $D_{PM\;on\;Cecum}/D_{NaFluo}=0.292{\pm}0.151$, $D_{PM\;on\;Kidney}/D_{NaFluo}=0.218{\pm}0.110$). The proposed method allows direct quantitative measurement of the three-dimensional diffusion in local PM in vivo, which was previously inaccessible by peritoneal function test methods such as peritoneal equilibration test (PET) and standardized PM assessment (SPA). f-FRAP is promising for local and dynamic assessments of peritoneal pathophysiology and the mass transport properties of PMs, presumed to be affected by variation of tissue structures over different organs and functional changes of the PM with years of peritoneal dialysis.

The purpose of this study was to evaluate and compare the effectiveness of ilioinguinal-hypogastric nerve blocks(IHNB) and caudal block in producing post-orchiopexy and post-heniorrhaphy analgesia in children. Forty consenting healthy children, ages 3~10yr, were randomly assigned to receive caudal bupitvacaine (0.125%, 0.5ml/kg), or IHNB bupivacaine (0.25%, 0.3 ml/kg). Blocks were performed following the induction of general anesthesia, be fore the operation. Pre-anesthetic medication in form of atropine 0.01 mg/kg, droperidol 0.05 mg/kg were given intramuscularly one hour before induction to 40 children. Children were induced with thiopental sodium 5 mg/kg and succinylcholine 1 mg/kg intravenously. Anesthesia was maintained with oxygen-nitrous oxide ($FiO_2$ 0.3) and ethrane. When the patients stabilized after induction. IHNB was done in the supine position and caudal block was done in the lateral position. The local anaesthetic was injected after negative aspiration. Postoperative pain was assessed with face pain rating scale (RPRS) at rest on discharge of recovery room, and 5 hours after discharge of recovery room, and the "red and white" visual analogue scale (VAS) at rest and mobilization from supine to sitting position on discharge of recovery room, and 5 hours after discharge of recovery room. Post-operative recovery was quiet and comfortable, without side effect. Relief of ain was complete in both IHNB group and caudal group. Surgeons, parents and recovery room personnel were satisfied. There were no surgical or anesthetic complications. In our study, the postpoerative pain scores were similar in both IHNB group and caudal group. IN conclusion, we found that both IHNB and caudal blocks before the start of surgery for orchiopexy & herniorrhaphy are safe and effective in controlling the postoperative pain of children.

Over the past two decades, the options for solid waste management have been changing from land disposal to recycling, waste-to-energy, and incineration due to growing attention for resource and energy recovery. In addition, the reduction of greenhouse gas (GHG) emission has become an issue of concern in the waste sector because such gases often released into the atmosphere during the waste management processes (e.g., biodegradation in landfills and combustion by incineration) can contribute to climate change. In this study, the emission and reduction rates of GHGs by the municipal solid waste (MSW) management options in D city have been studied for the years 1996-2016. The emissions and reduction rates were calculated according to the Intergovernmental Panel on Climate Change guidelines and the EU Prognos method, respectively. A dramatic decrease in the waste landfilled was observed between 1996 and 2004, after which its amount has been relatively constant. Waste recycling and incineration have been increased over the decades, leading to a peak in the GHG emissions from landfills of approximately $63,323tCO_2\;eq/yr$ in 2005, while the lowest value of $35,962tCO_2\;eq/yr$ was observed in 2016. In 2016, the estimated emission rate of GHGs from incineration was $59,199tCO_2\;eq/yr$. The reduction rate by material recycling was the highest ($-164,487tCO_2\;eq/yr$) in 2016, followed by the rates by heat recovery with incineration ($-59,242tCO_2\;eq/yr$) and landfill gas recovery ($-23,922tCO_2\;eq/yr$). Moreover, the cumulative GHG reduction rate between 1996 and 2016 was $-3.46MtCO_2\;eq$, implying a very positive impact on future $CO_2$ reduction achieved by waste recycling as well as heat recovery of incineration and landfill gas recovery. This study clearly demonstrates that improved MSW management systems are positive for GHGs reduction and energy savings. These results could help the waste management decision-makers supporting the MSW recycling and energy recovery policies as well as the climate change mitigation efforts at local government level.

Recently, new keywords such as "Resilience" and "Repairability" have been discussed from the perspective of the sustainability of damaged structures after a severe disaster. To evaluate the repairability and recovery of structures, it is necessary to establish an analytical method that can simulate the behavior of repaired structures. Furthermore, it is desirable to establish an evaluation method for the structural performance of repaired structures. This study investigates the repairability and recovery of steel members that are damaged by local buckling or cracks. This paper suggests a simple analytical model for repaired steel members, in order to simulate the inelastic behavior and evaluate the recoverability of the structural performance. There is good agreement between the analytical results and the test results. The proposed analytical method and model can effectively evaluate the recoverability.
