Simultaneous implant installation with bone graft was performed in 15 cases. Four cases were cleft alveolus patients. 56 implants were placed immediately with block bone grafts. 2 cases were cranial bone grafts and the others were iliac bone grafts. Three of 56 implants were lost(94.6% Survival rate). One of three was cleft alveolus case. The cleft alveolus patients with simultaneous implants installation showed functional and esthetic results without infraocclusion and positional changes. Bergland index was considered to be type I after 12 months later. Immediate implant installation with bone graft is one of choice of treatment in closing cleft alveolus hoping simultaneous implant installation could be related with function which might result in less resorption of graft. Functional and esthetic results are satisfaction ; there was no infraocclusion and positional changes.

폐수수탁처리업에 반입되는 산업폐수의 원수 성상이 매일 달라짐에 따라 전처리 공정인 응집침전공정의 효율적 운전이 어려운 실정이며, 이로 인해 후처리공정인 증발농축 및 대체 공정인 membrane 공정의 부하원인이 되고 있다. 이에 본 연구에서는 산업폐수의 효율적 처리를 위해 응집제 주입 방법별(단독주입, 동시주입, 순차주입, 역주입) 응집특성을 비교하기 위해 NaOH 주입 전 후 폐수 원수를 채수하여 실험하였다. 응집실험은 Jar-tester를 이용하여 진행하였다. 응집제주입방법별 TDS 제거효율은 순차주입(2.8 %) < 단독주입(3.9 %) < 동시주입(8.1 %) < 역주입(9.6 %) 순으로, TOC 제거효율은 단독주입(84.3 %) < 역주입(86.2 %) < 순차주입(88.6 %) < 동시주입(89.1 %) 순으로, 탁도 제거효율은 단독주입(99.7 %) < 순차주입(99.8 %) ${\fallingdotseq}$ 역주입(99.8 %) < 동시주입(99.9 %) 순으로 각각 나타내어, 이를 종합적으로 고려하여 판단한 결과 순차주입방법(무기응집제${\rightarrow}$고분자응집제)보다 무기응집제 및 고분자응집제를 동시에 주입하는 방법이 더 효율적인 것으로 나타났다.

Bisphosphonates are widely used mainly for the treatment of osteoporosis and bone metastasis of malignancy. Since the first report of MRONJ, there have been many studies associated, however the pathogenesis of MRONJ is not yet clear. Medication-related osteonecrosis of the jaws (MRONJ) is a serious complication associated with long-term medication therapy. It is characterized by exposed necrotic bonein the jaw, which has persisted for more than 8weeks despite continuous treatment by dentist. The mechanism of development of MRONJ is still unclear and there is no definitive standard treatment for MRONJ. The purpose of this study is to investigate the jaw bone destruction mechanism of accumulated bisphosphonates, so that we can develop therapeutic method to repair the defect and stop the destruction process. The authors performed simultaneous application of PRF(Platelet rich fibrin) and BMP-2(Bone morphogenetic protein-2) to stimulate not only soft tissue healing but also osseous regeneration. Our case series demonstrate that simultaneous application of platelet rich fibrin and bone morphogenetic protein-2 can be a treatment of choice for MRONJ.

When a comparison is made with respect to the unknown best treatment, Hsu (1984, 1985) proposed the so called multiple comparisons procedures with the best in the analysis of variance model. Applying Hsu's results to the analysis of covariance model, simultaneous confidence intervals for multiple comparisons with the best in a balanced one-way layout with a random covariate are developed and are applied to a real data example.

A female child with unilateral midpalatal cleft was successfully treated by Wardill V-Y pushback palatal flap and superiorly based pharyngeal flap simultaneously. The advantages of this method are to prepare the favorable background of postoperative speech correction and additional nasal lining. We can try this simultaneous operation in delayed cleft palate repair.

Air space disorders are usually considered medical diseases, although some patients with air space disorders can benefit from surgical intervention. Recently we experienced two cases of bullous emphysema. One case is large bilateral apical bullae and the other is infected large bulls of RUL with bullous emphysema. The patient with large bilateral apical bullae underwent simultaneous operation via bilateral thoracotomy and other patient underwent simultaneous bilateral operation via median sternotomy. Postoperatively, the patient with large bilateral apical bullae showed subjective as well as objective improvement and other patient is resulted subjective improvement.

Dyeability and colorfastness of the blended knits of cotton/rayon (40/60; C/R) and wool/tencel (10/90; W/T) are examined using the natural dyestuff ($Pinux^{TM}$) manufactured from Pinus radiata pine bark extract. In addition, pre-treatments (such as bleaching, mercerization and cationization) are performed to improve dyeability and colorfastness. The $Pinux^{TM}$ powder dyestuffs produced by Pinux Co., Ltd. are used as dyestuffs and their properties are examined for dyeing concentration (0.5-2% (owb)), dyeing time (30-120 minutes) and dyeing temperature (30-$90^{\circ}C$). Dyeability is evaluated with K/S value at 400nm, which is the maximum absorption wavelength for $Pinux^{TM}$. The results show the dyeability of W/T sample containing protein fiber with $Pinux^{TM}$ is superior to all cellulose fiber C/R. A concentration of dyestuff greater than 1.5% (owb), dyeing time 120 minutes and dyeing temperature of $90^{\circ}C$ are the most optimized conditions. It shows that the dyeability of C/R and W/T samples are high in the condition of an acid-dyeing bath and that dyeability highly declined in alkaline bath due to the instability of the proanthocyanidin pigment. After analyzing the effect of bleaching, mercerizing and cationizing (as pre-treatments on dyeability) it was concluded that the dyeability of the C/R sample was enhanced by mercerization but no significant effect by cationization. However, the simultaneous treatment of cationizing and dyeing resulted in far improved dyeability compared to dyeing after cationizing pre-treatment. As for the W/T sample, the effect of cationization was more prominent than the C/R sample. Colorfastness to color changes in the control W/T sample was higher than that of C/R's level 1-2, and it increased to Level 2 when bleaching pre-treatment was given and when a simultaneous cationizing treatment was adopted to the dyeing process. Colorfastness to light in W/T control sample resulted in Level 3 and further increased to an excellent Level of 4 with bleaching and simultaneous cationizing during dyeing process.

Objectives : The aim of this study was to report the cases of knee injury that are treated with both CPM and Korean medicine. Methods : We treated 3 patients who had knee joint pain and gait disturbance by knee injuries with Korean medicine and CPM treatment. We evaluated the outcomes by checking NRS, ROM, Lysholm knee score, walking state and other symptoms. Results : The NRS, ROM, Lysholm knee score, and other symptoms of 3 patients were improved before they. These results show possibilities of simultaneous treatment of Korean medicine and CPM. But there is a limit that the number of cases is not sufficient, and there was no long-term follow-up after discharge. Conclusions : Simultaneous treatment of Korean medicine and CPM has an effect on knee joint rehabilitation. Further studies are needed to prove the effectiveness of Korean medicine combined with CPM.

In this report, we describe the successful use of alternate rapid maxillary expansions and constrictions with a hybrid hyrax-mandibular miniplate combination and simultaneous orthodontic treatment for the management of severe Class III malocclusion due to maxillary hypoplasia in an 11-year-old girl. The devices were removed after 20 months of treatment, and the family was instructed about a careful control and retention program that should be followed in accordance with the patient's growth. The final result included the correction of Class III malocclusion with adequate function and excellent facial esthetics, which restored the patient's self-esteem and provided personal motivation. The outcomes showed good stability after 24 months of retention. The decrease in the duration of active treatment is the most important finding from the present case. Considering that facial esthetics in adolescence is a determining factor for the development of a personality and interpersonal relationships, we recommend the use of this protocol for growing patients, who will exhibit not only an improved physical appearance but also a better quality of life.

An overdose of antihypertensive agents, such calcium channel blockers (CCBs) and angiotensin II receptor blocker (ARBs), and the antihyperglycemic agent, metformin, leads to hypotension and lactic acidosis, respectively. A 40-year-old hypertensive and diabetic man with hyperlipidemia and a weight of 110 kg presented to the emergency room with vomiting, dizziness, and hypotension following an attempted drug overdose suicide with combined CCBs, ARBs, 3-hydroxy-3-methylglutaryl-coemzyme A reductase inhibitors, and metformins. A conventional medical treatment initially administered proved ineffective. The treatment was then changed to simultaneous extracorporeal membrane oxygenation (ECMO) and continuous renal replacement therapy (CRRT), which was effective. This shows that simultaneous ECMO and CRRT can be an effective treatment protocol in cases of ineffective conventional medical therapy for hypotension and lactic acidosis due to an overdose of antihypertensive agents and metformin, respectively.
