Purpose: The purpose of this study is to evaluate the effectiveness of oral positioning stent, the BinkieRT<sup>TM</sup> in radiation treatment for head and neck cancer patients in terms of tongue positions reproducibility, tongue doses and material properties. Materials and Methods: 24 cases using BinkieRT<sup>TM</sup> during radiation treatments were enrolled. The tongue was contoured on planning CT and CBCT images taken every 3 days during treatment, and then the DSC and center of tongue shift values were analyzed to evaluate the reproducibility of the tongue. The tongue dose was compared in terms of dose distribution when using BinkieRT<sup>TM</sup> and different type of oral stents (mouthpiece, paraffin wax). Randomly selected respective 10 patients were measured tongue doses of initial treatment plan for nasal cavity and unilateral parotid cancer. Finally, In terms of material evaluation, HU and relative electron density were identified in RTPS. Results: As a result of DSC analysis, it was 0.8 ± 0.07, skewness -0.8, kurtosis 0.61, and 95% CI was 0.79~0.82. To analyze the deviation of the central tongue shift during the treatment period, a 95% confidence interval for shift in the LR, SI, and AP directions were indicated, and a one-sample t-test for 0, which is an ideal value in the deviation(n=144). As a result of the t-test, the mean and SD in the LR and SI directions were 0.01 ± 0.14 cm (p→.05), 0.03 ± 0.25 cm (p→.05), and -0.08 ± 0.25 cm (p ←.05) in the AP direction. In the case of unilateral parotid cancer patients, the Dmean to the tongue of patients using BinkieRT<sup>TM</sup> was 16.92% ± 3.58% compared to the prescribed dose, and 23.99% ± 10.86% of patients with Paraffin Wax, indicating that the tongue dose was relatively lower when using BinkieRT<sup>TM</sup> (p←.05). On the other hand, among nasal cavity cancer patients, the Dmean of tongue dose for patients who used BinkieRT<sup>TM</sup> was 4.4% ± 5.6%, and for those who used mouthpiece, 5.9% ± 6.8%, but it was not statistically significant (p→.05). The relative electron density of Paraffin Wax, BinkieRT<sup>TM</sup> and Putty is 0.94, 0.99, 1.26 and the mass density is 0.95, 0.99 and 1.32 (g/cc), Transmission Factor is 0.99, 0.98, 0.96 respectively. Conclusion: The result of the tongue DSC analysis over the treatment period was about 0.8 and Deviation of the center of tongue shifts were within 0.2 cm, the reproducibility was more likely excellent. In the case of unilateral head and neck cancer patients, it was found that the use of BinkieRT<sup>TM</sup> rather than Paraffin Wax or Putty can reduce the unnecessary dose irradiated to the tongue. This study might be useful to understand of BinkieRT<sup>TM</sup>'s properties and advantages. And also it could be another considered option as oral stent to keep the reproducibility of tongue and reducing dose during head and neck radiation treatments.

Mobile Ad-hoc Networks(MANETs)에서 정책기반 네트워크 관리를 위해서는 기존의 유선망 관리 방법으로는 신뢰성과 효율성을 보장 할 수 없다. 그러므로 MANETs 관리는 노드들을 효과적으로 클러스터하고 이동 관리를 하는 것이 필수적이다. 본 논문에서는 분산 되어 있는 PDP(Policy Decision Point)를 발견하는 Active PDP Discovery Protocol과 PEP(Policy Enforcement Point)노드 이동 감지를 위해 COPS-PR을 확장하고 PDP에 MNL(Management Node List)를 추가하여 PEP노드를 관리하는 방법을 제안한다. 그리고 시뮬레이션을 통해 얻은 결과를 분석하고 결론으로 끝맺는다. Policy-based Network Management(PBNM) in the Mobile Ad-hoc network(MANETs) requires additional, reliable and efficient mechanism over PBNM in wired network. Thus, it is important that the management system in MANETs should cluster the moving nodes and manage their movements in an effective manner. In this thesis, I propose a mechanism for the policy-based management in ad hoc networks in which I consider several methods to discover the Policy Decision Point(PDP), set the management area, and manage the movements of Policy Enforcement Point(PEP) nodes in the PBNM system. Moreover, COPS-PR is extended for the mechanism. Finally, I analyze and validate the results through simulations.

Objective: To evaluate incidence of microbial growth from the tip of the embryo transfer catheter after embryo transfer in relation to clinical pregnancy rate following in-vitro fertilization and embryo transfer. Method: This study was performed prospectively at the time of transcervical embryo transfer following conventional in-vitro fertilization and intracytoplasmic sperm injection procedures. Sixty three patients were enrolled in this study. Microbiological cultures were performed on endocervical swabs and embryo transfer catheter tips. Results: Positive microbial growths were observed from endocervical swabs in 45 (71.4%) women and from catheter tips in 30 (47.6%) women. There was no statistically significant difference seen in the mean number of oocytes fertilized or number and grade of embryos transferred between the group of patients without growth and the group of patients with positive microbial growth from catheter tips. The clinical pregnancy rate were 30.3% in the group of patients without growth and 13.3% in the group with positive microbial growth from catheter tips. This difference in clinical pregnancy rates was statistically significant. Conclusion: Our finding is that microbial contamination at embryo transfer may influence implantation rates. The major questions arising from our finding are whether eradication of endocervical micro-organisms is possible and whether their eradication will improve implantation rates.

최근 수질환경보전법의 개정법률(안)에 의거하여 폐 · 하수종말처리장에 수온, pH, 생물학적산소요구량(BOD), 화학적산소요구량(COD), 총질소(TN), 총인(TP) 및 부유물질(SS)의 자동으로 측정할 수 있는 수질 자동측정기의 부착이 의무화될 예정에 있다. 그러나, 현재 전국적으로 화학적산소요구량 측정장비와 같이 일부 항목에 대한 자동측정장치는 설치 · 운영 중인 곳이 많이 있으나, 수질 TMS 설치 규정에 나와 있는 전 항목을 측정할 수 있는 장비가 설치되어 운영하는 곳은 극히 일부에 불과한 실정이다. 따라서, 수온, ph, 화학적 산소요구량(COD), 총질소(TN), 총인(TP), 부유물질(SS) 자동측정 장치를 설치하고, 무선통신(CDMA)방식을 이용하여 ‘방류수 수질 원격감시체계(TMS) 시범 운영'을 통하여, 측정 장비들에 대한 자료의 정확성, 신뢰성을 파악하여 설치된 장비들에 대한 성능을 사전에 평가하고, 수질 TMS 시스템에 대한 현장 적응 능력 및 안정성을 파악하여 실질적으로 운영되는 시점에 좀 더 정확하고 실용적인 시스템의 적용하고자 한다.

We report 1 patient with Primary aldosteronism caused by malfunction of adrenal gland. which occupies 1-2% of the whole Hypertensive disease. The patient was 35 year-old female with the history of hypertension. She was hospitalized at Department of Circulatory Internal Medicine. College of Oriental Medicine, Kyung Hee University, Seoul, because of low limb weakness, chest discomport, palpitation and dry mouth. The value of serum potassium level was o.6 and at last adenoma was diagnosed on the basis of abdomen CT scan. The Primary aldosteronism manifests myasthenia, headache, dry mouth, palpitation. In laboratory findings, it especially shows specific U -wave in EKG due to low serum potassium level resulted from excessive flow-out through urine. It could be regarded as ‘Flaccid paralysis of Limbs(?症)‘, the Oriental medical term which indicates a condition of general weakness. We report on this case with a review of literature.
