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.

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.

Purpose: The purpose of this study is to evaluate the effectiveness of oral positioning stent, the BinkieRT^TM 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^TM 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^TM 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^TM 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^TM (p←.05). On the other hand, among nasal cavity cancer patients, the Dmean of tongue dose for patients who used BinkieRT^TM 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^TM 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^TM rather than Paraffin Wax or Putty can reduce the unnecessary dose irradiated to the tongue. This study might be useful to understand of BinkieRT^TM'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.

본 연구는 L형, I형 실험체에 강판 콘크리트 구조와 철근콘크리트 구조를 적용하여 이질접합부를 만들고, 실험체에 반복하중을 파괴 시 까지 가력하여 면외 휨 내력 및 면내 전단 내력을 평가하고 구조특성을 검토하기 위해서 실험연구를 수행하였다.본 연구에서 면외 휨 성능실험은 접합부에서 정착부 수직철근이 인발되면서 파괴되었고, 면내 전단성능실험은 기초부에서의 휨 균열이 발생하여 파괴되었으며, 이론식과의 비교결과 최대 내력이 실험값/이론값의 결과가 면외 휨성능실험은 96%, 면내 전단성능실험은 82%의 값을 나타내었다. This paper describes an experimental study on the mechanical characteristic and behavior of a structure that has a joint between the reinforced concrete (RC) member and steel plate concrete (SC) member. An out-of-plane flexural test on an L-type test specimen and in-plane shear test on an I-type test specimen were carried out by means of repeated cyclic loading until their failure. Based on the results, the former showed pull-out failure mode of anchored vertical bars while the latter exhibited flexural failure mode of the basement member. These results reveal that the maximum capacity of the specimens is 96% and 82%, respectively, compared with the theoretical value.
