Domestic water supply and sewage facilities are rapidly aging and maintenance difficulties such as aging of operation and management personnel are overlapping, so Digital Twin technology is attracting attention as an intelligent means of process management. Digital twin projects for domestic water treatment processes include the smart sewage treatment project promoted by the Ministry of Environment, projects independently promoted by some local governments, and digital twin purification plant projects promoted by K-water. However, the content of digital twin promotion is different for each institution. Therefore, in the water treatment process, technological standardization and step-by-step implementation methods for digital twins must be preceded to reduce trial and error in future business promotion. This study aims to provide an efficient promotion plan by prescribing the digital twin element technology and composition method in the water treatment process and reviewing the contents currently being promoted by the Ministry of Environment, local governments, and K-Water individually.

Objective : Stent-assisted coiling on intracranial aneurysm has been considered as an effective technique and has made the complex aneurysms amenable to coiling. To achieve reconstruction of intracranial vessels with preservation of parent artery the use of stents has the greatest potential for assisted coiling. We report the results of our experiences in ruptured wide-necked intracranial aneurysms using Y-stent coiling. Methods : From October 2003 to October 2011, 12 patients (3 men, 9 women; mean age, 62.6) harboring 12 complex ruptured aneurysms (3 middle cerebral artery, 9 basilar tip) were treated by Y-stent coiling by using self-expandable intracranial stents. Procedural complications, clinical outcome, and initial and midterm angiographic results were evaluated. The definition of broad-necked aneurysm is neck diameter over than 4 mm or an aneurysm with a neck diameter smaller than 4 mm in which the dome/neck ratio was less than 2. Results : In all patients, the aneurysm was successfully occluded with no apparent procedure-related complication. There was no evidence of thromboembolic complication, arterial dissection and spasm during procedure. Follow-up studies showed stable and complete occlusion of the aneurysm in all patients with no neurologic deficits. Conclusion : The present study did show that the Y-stent coiling seemed to facilitate endovascular treatment of ruptured wide-necked intracranial aneurysms. More clinical data with longer follow-up are needed to establish the role of Y-stent coiling in ruptured aneurysms.

Objective : Microvascular decompression (MVD) for hemifacial spasm (HFS) is a safe and effective treatment with favorable outcomes. The purpose of this study was to evaluate the incidence of delayed cranirve (VI, VII, and VIII) palsy following MVD and its clinical courses. Methods : Between January 1998 and December 2009, 1354 patients underwent MVD for HFS at our institution. Of them, 100 patients (7.4%) experienced delayed facial palsy (DFP), one developed sixth nerve palsy, and one patient had delayed hearing loss. Results : DFP occurred between postoperative day number 2 and 23 (average 11 days). Ninety-two patients (92%) completely recovered; however, House-Brackmann grade II facial weakness remained in eight other patients (8%). The time to recovery averaged 64 days (range, 16 days to 9 months). Delayed isolated sixth nerve palsy recovered spontaneously without any medical or surgical treatment after 8 weeks, while delayed hearing loss did not improve. Conclusion : Delayed cranial nerve (VI, VII, and VIII) palsies can occur following uncomplicated MVD for HFS. DFP is not an unusual complication after MVD, and prognosis is fairly good. Delayed sixth nerve palsy and delayed hearing loss are extremely rare complications after MVD for HFS. We should consider the possibility of development of these complications during the follow up for MVD.

In highly developed society, information and communication technologies are widely used for better medical services. These information and communication technologies should be more and more acceptable in all hospitals for exchange medical records. EMR becomes more convenient than the previously used paper charts. It will be able to record medical institutions every time and dual treatment. Each is different specifications for each medical institution to use the program or document to exchange it. The personal clinic records still does not exchange well. To solve this gap between medical alienation, this paper describes the concepts of HL7-CDA and proposes types of telemedicine system. To resolve time and space constraints, new form of treatment methods presents in future directions after described about related systems. CDA enables electronic medical records to the each medical center and gradually expanded by exchanging the patient's medical records. This paper is using XML-based CDA documents as a hierarchical for medical information exchange standards compliant HL7-CDA documents. It could be possible currently used structural variety of multimedia data. Thus It is able to send and receive HL7-CDA-based medical information and clinical information to identify the medical institutions of medical information with interchange system design and building standards, and through mutual exchange of clinical information.

Objectives This is one of the manuals of East-West integrative medicine which was created by the committee on integrative medicine of Chung-Yeon Korean Medicine Hospital. The purpose of this manual is to support clinical decision-making and communication between Korean and western medical staff in a Korean medicine hospital during the rehabilitation of patients after knee surgery. Methods The draft was made by two rehabilitation specialists in Korean medicine. After a rehabilitation specialist in western medicine reviewed the draft and exchanged their ideas, a revised version that reflects the goal of consultation was made. Then the committee agreed to adopt the manuals through the process of review and feedback in addition to face-to-face discussions. Results This manual describes clinical decision-making for rehabilitation after arthroscopic partial meniscus resection, meniscus refixation, reconstruction of anterior and posterior cruciate ligaments. Therefore, it contains the schedule of rehabilitation treatment by the surgical technique, general goal of the rehabilitation by phase, guide for patients and postoperative infection management. Conclusions Despite some limitations, this manual has significance as the first example of a decision-making protocol suggestion for East-West integrative rehabilitation treatment after a knee surgery in one medical institution.

Background: Recently the use of sedation by pediatric dentists in Korea is increased. This study describes training programs about sedation practices in Korean pediatric dentistry residency program. Methods: A questionnaire was filled in by participants of Korean Academy of Pediatric Dentistry on 17th-18th August, 2008. Also the data about sedation practices of the training institution is collected by phone call. Results: Seventy two percent of respondents used sedation. Most of them used sedation with agents under 25% of their patients. Distribution of ages in patients sedated with agents was 3 years, 4-5 years, under 2 years, 6-10 years, and more than 10 years. Determinative factors of using sedation were behavior management, number of visiting, amount of treatment and general condition, and oral route was the most favorable route. Sixty six percent of them have failed on sedation, and thity percent of them have rarely failed on sedation. Only fifty percent of dentists using sedation completed the cardiopulmonary resuscitation course. Conclusions: For safety, dentists using sedation need to be educated about emergency equipment and management. Especially medication dose, use frequency and the detail related to treatment procedure should be discussed carefully. Also putting a patient under general anesthesia and taking emergency measures should be discussed with Korean Dental Society of Anesthesiology.

The aim of this study was to evaluate the in vitro effects of exposure to acidic beverages on microhardness of enamel and dentin. Thirty enamel specimens and thirty dentin specimens were obtained from extracted bovine maxillay incisiors. Enamel and dentin specimens were divided into three groups and treated with acidic beverages as follows; Group 1 : cola(pH 2.52), Group 2 : plain soda water(pH 2.93) and Group 3 : orange juice(pH 3.75). Erosive treatment was performed by storing each specimens for 5 min in 50ml solution of cola, soda water and orange juice. Average microhardness values(VHN) were determined before and after erosive treatment. All beverages produced significant loss of microhardness of enamel and dentin. Microhardness of enamel was reduced in the following order: Group 1 : $42.71{\pm}4.36(%)$, Group 2 : $37.09{\pm}6.25(%)$, Group 3 : $35.46{\pm}4.98(%)$. Microhardness of dentin was reduced in the following order: Group 1 : $17.14{\pm}3.42(%)$, Group 2 : $13.89{\pm}3.18(%)$, Group 3 : $13.82{\pm}3.50(%)$. The differences between group 1 and group 2, 3 were statistically significant(p< 0.05).

Background: Verrucous carcinoma (VC) accounts for 1-10% of cases of squamous cell carcinoma (SCC) in the oral cavity, and 75% of VC occur in the oral cavity. Only 3% of primary intraosseous squamous cell carcinomas (PIOSCC), which means SCC occurring primarily in the bone, are VC. Verrucous carcinoma arising from odontogenic cysts (OC) is very rare, with only seven cases reported to date. Case presentation: This study reported a case of a patient who underwent partial maxillectomy and neck dissection for VC that occurred in the right anterior maxilla. The patient was admitted to the emergency department at our institution 8 years ago and showed cystic lesions in the anterior maxilla on facial computed tomography (CT) images. Treatment through other departments including assessment of laceration in the mental region and only suture was performed. This report highlights a very rare case of VC in the right anterior maxilla arising from a previous cystic lesion. Conclusions: Since PIOSCC can arise from OC, appropriate treatment of intraosseous cysts and regular radiologic evaluation are necesssary. Surgical exicision of the primary lesion without neck dissection can lead to good prognosis for patients with primary intraosseous verrucous carcinoma.

Purpose: We evaluated the clinical outcomes of the non-operative management of post-gastrectomy duodenal stump leakage in patients with gastric cancer. Materials and Methods: A total of 1,230 patients underwent gastrectomy at our institution between 2010 and 2014. Duodenal stump leakage was diagnosed in 19 patients (1.5%), and these patients were included in this study. The management options varied with patient condition; patients were managed conservatively, with a pigtail catheter drain, or by tube duodenostomy via a Foley catheter. The patients' clinical outcomes were analyzed. Results: Duodenal stump leakage was diagnosed in all 19 patients within a median of 10 days (range, 1~20 days). The conservative group comprised of 5 patients (26.3%), the pigtail catheter group of 11 patients (57.9%), and the Foley catheter group of 3 patients (15.8%). All 3 management modalities were successful; none of the patients needed further operative intervention. The median hospital stay was 18, 33, and 42 days, respectively. Conclusions: Non-operative management of duodenal stump leakage for selected groups of patients with gastric cancer was effective for control of intra-abdominal sepsis. This management modality can help obviate the need for surgical intervention.
