  • In this paper, for magnetic silence technology of naval vessel, is to make lab deperm system and to evaluate the deperm capacity of naval vessel regarding deperm protocol. Initial permanent magnetic field of naval vessel is magnetized before deperm, having the magnetic field of the same size, to evaluate the deperm capacity regarding a variety of deperm protocol for experimental reliability growth. Current dead time effect of deperm protocol is measured at the different initial current, which are 8A, 6A and 4A respectively. Furthermore, the experiment under the same condition except changing duty cycle into 50% is carried out. As a result, it is possible to compare the six different experiment outcomes. The result shows that the experiment with dead time improve the deperm capacity more than 48.51 percent comparing to the case without dead time.

  • Accelerated partial breast irradiation (APBI) is a new treatment delivery technique that decreases overall treatment time by using higher fractional doses than conventional fractionation. Here, a quantitative analysis study of CyberKnife-based APBI was performed on 10 patients with left-sided breast cancer who had already finished conventional treatment at the Inha University Hospital. Dosimetric parameters for four kinds of treatment plans (3D-CRT, IMRT, VMAT, and CyberKnife) were analyzed and compared with constraints in the NSABP B39/RTOG 0413 protocol and a published CyberKnife-based APBI study. For the 10 patients recruited in this study, all the dosimetric parameters, including target coverage and doses to normal structures, met the NSABP B39/RTOG 0413 protocol. Compared with other treatment plans, a more conformal dose to the target and better dose sparing of critical structures were observed in CyberKnife plans. Accelerated partial breast irradiation via CyberKnife is a suitable treatment delivery technique for partial breast irradiation and offers improvements over external beam APBI techniques.

  • Cleft lip and palate is one of the congenital anomalies which need comprehensive and multidisciplinary treatment plan because 1) oral cavity is an important organ with masticatory function as a start of digestive tract, 2) anatomic symmetry and balance is esthetically important in midfacial area, and 3) it is also important to prevent psycho-social problems by adequate restoration of normal facial appearance. There are many different protocols in the treatment of cleft lip and palate, but our department has adopted and modified the $Z{\"{u}}rich$ protocol, as published in the Journal of Korean Cleft Lip and Palate Association in 1998. The first challenge is feeding. Type of feeding aid ranges from simple obturators to active orthopedic appliances. In our department we use passive-type plate made up of soft and hard acrylic resin which permits normal maxillary growth. We use Millard's method to restore normal appearance and function of unilateral complete cleft lip. In consideration of both maxillary growth and phonetic problems, we first close soft palate at 18 months of age and delay the hard palate palatoplasty until 4 to 5 years of age. When soft palate is closed, posterior third of the hard palate is intentionally not denuded to allow normal maxillary growth. In hard palate palatoplasty the mucoperiosteum of affected site is not mobilized to permit residual growth of the maxilla. We have treated a patient with unilateral complete cleft lip and palate by Ajou protocol, which is a kind of modified $Z{\"{u}}rich$ protocol. It is as follows: Infantile orthopedics with passive-type plate such as Hotz plate, cheiloplasty with Millard's rotation-advancement flap, and two stage palatoplasty. It is followed by orthodontic treatment and secondary osteoplasty to augment cleft alveolus, orthognathic surgery, and finally rehabilitation with conventional prosthodontic treatment or implant installation. The result was good up to now, but we are later to investigate the final result with longitudinal follow-up study according to master plan by Ajou protocol.

  • The recent advances in the basic hematology and immunology have significantly enhanced the understanding of histiocytic disorders. The Histiocyte Society which was established in 1985 enabled the randomized trials for these diseases, and important knowledge regarding pathogenesis, clinical presentation, diagnosis, therapy and late consequences has been obtained. The treatment of Langerhans cell histiocytosis (LCH) has varied greatly over last decades, and is still controversial. Therapy can be reduced for low risk patients, and it is possible to discriminate early the non-responding patients with risk disease who might require more intensified treatment. Current therapy of LCH recommended by the Histiocyte Society (LCH-III protocol) is activated in 2001. Hemophaocytic histiocytosis (HLH) is fatal if diagnosis is delayed and appropriate therapy is not instituted rapidly. The diagnostic criteria for HLH is revised by the Histiocyte Society for the current treatment protocol (HLH-2004) which consists of dexamethasone, etoposide, and cyclosporin in combination with intathecal methotrexate. Hematopoietic stem cell transplantation is usually necessary for the primary HLH and recurrent secondary HLH.

  • Objective : This study was done to define the treatment protocol of Traditional Korean Medicine for persistent allergic rhinitis, which might be necessary for conducting PRCT study. Methods : Data were collected by questionnaire from Korean Medicine doctors participated in the Conference of The Korean Oriental Medical Ophthalmology & Otolaryngology & Dermatology Society in October 2012. We investigated their treatment procedures for persistent allergic rhinitis in ordinary clinical settings. Their treatment patterns including annual treatment period, frequencies and treatment times were also investigated. Finally, we combined the national insurance covered or out-of-pocket treatments as treatment packages according to the response rates of each contents, and displayed them as treatment protocols for PRCT study. Results : 50 Korean medicine doctors described the informed consent and questionnaire. Response rates of each treatment procedure were listed in Table 2 to Table 5. Treatment periods, frequencies and treatment time of each visit were listed in Table 6. Finally, treatment packages which would be defined for PRCT were listed in Table 7 as treatment package 1(response rates were over 50%), package 2(response rates were over 25%), package 3(response rates were over10%). Conclusion : These results provide the rational background and preliminary sources of defining treatment packages for developing PRCT protocols.

  • In this study, we propose a rehabilitation protocol involving Korean medicine for patients after high tibial osteotomy (HTO) and report its effectiveness. Three patients underwent HTO using the rehabilitation protocol involving Korean medicine. We estimated the outcome evaluating physical examination findings of the knee joint, numeric rating scale, pain disability index, Lysholm knee score, and walking state. After the treatment, we observed that knee movement and muscular strength were improved. In addition, the numeric rating scale, pain disability index, Lysholm knee score, and walking state of patients were improved. Therefore, a rehabilitation protocol involving Korean medicine can be effectively used for patients after HTO. The limitation of this study was the insufficient number of cases and the difficulty of follow-up because of the characteristics of this operation and the long periods of time that are needed for each phase of the protocol. Further studies are needed to design a rehabilitation protocol involving Korean medicine.

  • Computer Assisted Simulation Surgery (CASS) is a reliable method that permits oral and maxillofacial surgeons to visualize the position of the maxilla and the mandible as observed in the patient. The purpose of this report was to introduce a newly developed strategy for proximal segment management according to Balanced Orthognathic Surgery (BOS) protocol which is a type of CASS, and to establish the clinical feasibility of the BOS protocol in the treatment of complex maxillo-facial deformities. The BOS protocol consists of the following 4 phases: 1) Planning and simulation phase, 2) Modeling phase, 3) Surgical phase, and 4) Evaluation phase. The surgical interventions in 80 consecutive patients were planned and executed by the BOS protocol. The BOS protocol ensures accuracy during surgery, thereby facilitating the completion of procedures without any complications. The BOS protocol may be a complete solution that enables an orthognatic surgeon to perform accurate surgery based on a surgical plan, making real outcomes as close to pre-planned outcomes as possible.

  • Cleidocranial dysplasia (CCD), an autosomal dominant disorder with a prevalence of 1 in 1,000,000 individuals, is mainly caused by mutations in Runx2, a gene required for osteoblastic differentiation. It is generally characterized by hypoplastic clavicles, narrow thorax, and delayed or absent fontanel closure. Importantly, its orofacial manifestations, including midfacial hypoplasia, retained primary teeth, and impacted permanent and supernumerary teeth, severely impede the well-being of affected individuals. Successful treatment of the orofacial problems requires the combined efforts of dental specialists. However, only a few successfully treated cases have been reported because of the rarity of CCD and complexity of the treatment. This article presents the University of California, San Francisco (UCSF) treatment protocol for the dentofacial manifestations of CCD based on two treated and 17 diagnosed cases. The records of two patients with CCD who had been treated at the UCSF School of Dentistry and the treatment options reported in the literature were reviewed. The UCSF treatment protocol produced a successful case and a partially successful one (inadequate oral hygiene in the retention stage resulted in decay and loss of teeth). It provides general guidelines for successfully treating the orofacial manifestations of CCD.

  • Accurate delivery of doses using a high dose rate(HDR) brachytherapy, remote afterloading system(RALS) depends on knowing the strength of the radioactive source at the time of treatment, the precision and consistency of the timer, and the ability of the unit to position the source at the proper dwell location along the applicator. Periodic Quality Assurance(QA) on HDR machines is a part of the standard protocol of any user. The safety of the patient & staff, positional accuracy, temporal accuracy, and dose delivery accuracy are periodically(weekly, quarterly, monthly) estimated using HDR source(Ir-192), treatment planning devices, measurement devices, and overall treatment devices with regard to treatment delivery. The overall measurement results are estimated successfully and assessed its clinical significance. As a result, our HDR brachytherapy units has been very accurate until now. The QA program protocol permits routine clinical use and provides a high confidence level in the accurate operation of HDR units. Therefore, regular QA of HDR brachytherapy is essential for successful treatment.

  • Recently, an advanced workflow has been introduced to finish implant surgery and prosthetic treatment in one-day. However, Because of 1. Patient's physical condition, 2. Surgical technique, 3. Digital technical limitations, the complete completion of one-day implant treatment is practically difficult. Therefore, this paper proposes a "two-days implant digital workflow" that short-time implant surgery and restores prosthetics the next day. Even though it takes more than one day, this workflow is a realistic implant treatment protocol that can reduce the chair time in the clinic.
