Since the cases of time extension have continuously transpired in the public construction project, the potential of economical loss and claims is increasing because the concerned parties such as an owner or a contractor have not properly performed their own responsibility for time extension. One of the main reasons is that the present planning and scheduling do not support the method to apportion the proper responsibility to the right party. This problem has repeatedly led to time extension and made it difficult for the concerned parties to perform the responsibility for time extension. In order to overcome this problem, a framework of delay administration is required as the method to apportion the proper responsibility to the right party. To solve this problem, this paper aimed to develop the conceptual model and prototype system as the practical method to administrate delay causation. Furthermore, the verification result for the reliability and applicability throughout the case studies on real construction projects shows that the conceptual model and prototype system developed would help efficiently to administrate the delay causation.

In this paper, we identify the code vulnerabilities that can be automatically detected through Visual Studio (VS) compiler and code analyzer based on a secure coding rule set which is optimized for development of battlefield information system. Then we describe a weak point item that can be dealt with at the implementation stage without depending on the understanding or ability of the individual programmer's secure coding through the implementation of the secure coding library. Using VS compiler and the code analyzer, the developers can detect only about 38% of security weaknesses. But with the help of the proposed secure coding library, about 48% of security weaknesses can be detected and prevented in the proactive diagnosis in the development stage.

Recently, jawbone osteonecrosis has been largely reported as a potential adverse effect of bisphosphonate (BP)administration. Currently available published incidence data for BRONJ are based on retrospective studies and estimates of cumulative incidence range from 0.8 to 12%. The mandible is more commonly affected than the maxilla (2:1 ratio), and 60-70% of cases are preceded by a dental surgical procedure. The signs and symptoms that may occur before the appearance of clinical evident osteonecrosis include changes in the health of periodontal tissues, non-healing mucosal ulcers, loose teeth and unexplained soft-tissue infection. Tooth extraction as a precipitating event is a common observation. The significant benefits that bisphosphonates offer to patients clearly surpass the risk of potential side effects; however, any patient for whom prolonged bisphosphonate therapy is indicated, should be provided with preventive dental care in order to minimize the risk of developing this severe condition.

Generally an operator would take notice at putting a patient under anesthesia. If the operation is executed in mistake, the patient is exposed to danger. The object of this Paper is that a system is developed for an accuracy of system and a convenience of user interface to prevent an operation of several elements of risk by mistake. The part of electrical system particularly is made for convenience of a manipulation using electrical switch and encoder. A real-time monitoring system is developed for an airway pressure and a gas concentration of carbon dioxide of patient using graphic LCD(liquid crystal display). Moreover, this flow control system could be developed control with accuracy by feedback control method. This is implemented using flow control valve and flow sensor. The implemented system gives convenience and precision of a manipulation of variable value using developed technique. This system shows guaranteed stabilization and confidence of anesthesia ventilator by notifying us that patient's state and information in case of being out of alarm range of variable value.

Damages from typhoon events have contributed more than 60 percent of total economic and social loss and the size of loss have been increased up to 800 million dollars per year in Korea, It is therefore necessary to make an effort to mitigate the loss of natural disasters. To facilitate the evaluation of damages in advance and to support the decision making to recover the damages, scientific methods have been adopted. With the effort, GIS data can provide various tools. Three components of hazard mapping are estimation of hazard, inventory for vulnerable features, and fragility of each feature. Vulnerability of natural disaster can be obtained by relation between loss and meteorological data such as precipitation and wind speed. Features can be categorized from other GIS data of public facilities and private properties, and then social and economic loss can be estimated. At this point, GIS data conversions for each model are required. In this study, we build a method to estimate typhoon risk based on GIS data such as DEM, land cover and land use map, facilities.

Dens evaginatus is an anomalous tooth development arising during morphodifferentiation. It is most often reported in premolar, and familial occurrence has been reported. The primary dental complication of dens evaginatus is fracture or wear of the tubercle which leads to pulp exposure, pulpal necrosis and periapical infection. Pathosis of the pulp can occur before complete root formation with cessation of root development. A rational and conservative approach to the management of dens evaginatus in vital teeth includes early diagnosis and treatment to prevent fracture or attrition of the tubercle. This treatment would include careful sequential grinding, pulp capping, preventive resin restoration. When presented with a case of dens evaginatus in a nonvital tooth with incomplete root development, the treatment of choice has been extraction, apexification. We report two cases of dens evaginatus that appear in two sisters. In the elder, a periapical lesion on radiographs is shown, and it is treated by calcium hydroxide apexification. The other sister is early recognized of dens evaginatus, it is treated using glass ionomer cement reinforcing with sequential grinding.

본 연구는 초기재혼부부의 결혼생활유지에 자기분화, 부부갈등대처방식에 미치는 효과의 프로그램을 개발하기 위한 사전 연구로서 재혼부부를 대상으로 자기분화, 부부갈등대처방식이 어떤 영향을 미치는지를 연구하고자 한다. 요구도 조사를 위한 포커스 인터뷰 대상은 서울과 경기도 수도권에 사는 부부이고 나이는 30세 이상에서 62세 미만을 선정하였으며, 재혼생활 기간이 1년 이상 6년 미만의 실질적 경험이 있는 부부를 선정하였으며, 부부 한쪽이라도 배우자가 전혼관계를 통해 자녀가 있는 복합가정을 선정하였다. 본 연구는 재혼부부를 대상으로 2017년 4월 4일부터 5월 25일까지 포커스 인터뷰를 실시하였다. 1회기에 100분씩 총 2회기로 개별적 인터뷰를 실시하였다. 포커스 인터뷰를 실시한 결과, 재혼부부들은 원가족에서 형성된 미분화로 역기능적인 습관들이 삼각관계를 형성하고 불안을 더욱 증폭시켰다. 부부가 문제해결을 하는 상황에서 낮은 자아분화 수준으로 표현하며 갈등을 더욱 고조시켰다. 낮은 자기분화수준은 갈등관계에서 자신을 이성과 감정을 분리하지 못하고 감정적으로 반응하기도 하며, 환경에 흡수되는 부정적 갈등 대처방식에도 영향을 미쳤다. 재혼부부에게 가장 취약한 면이 부부간 친밀감이며 유대관계이다. 전혼에서 상처와 부정적 정서로 인해 부부 신뢰감이 취약하였다. 비교적 짧은 재혼기간의 영향과 여러 갈등 요소 인 경제적 갈등, 계부모-친부모의 갈등, 계부모-계자녀의 갈등, 전 배우자와의 갈등, 부부간 잠재적 갈등 등으로 인해 친근한 부부유대관계를 맺지 못하는 어려움을 호소하기도 하였다. 특히 전혼관계의 배우자에 대한 부정적 경험이 남아 있을 경우 현재 배우자를 신뢰하지 못하는 갈등이 영향을 주고 있었다. 그로 인한 부부갈등의 악순환을 초래하는 것으로 나타났다. 본 연구는 재혼부부의 결혼생활유지를 돕는 자기분화, 갈등대처방식에 미치는 통합적 프로그램을 구성하려고 하는 필요성을 시사하는 것이다. 점진적으로 재이혼은 증가하여 부부 및 가족 구성원인 또 다시 부정적 영향을 미치고, 사회문제로 확산될 수 있음을 시사한다. 예방적 차원에서 재혼부부의 결혼생활유지 프로그램에 대한 필요성을 시사한다.

"Euibangyoochui" is a great medical encyclopedia composed of 91 symptoms and signs of diseases which classified 150 kinds of reference books. It consisted mainly of fifty thousands of herbal prescriptions and therapeutics but it deals with other treatments like diet therapy, precautions, acupuncture and moxibustion, physical and breathing exercises as well. Unlike other medical references, this book made up these treatments as independent chapters. We tried to catch the meanings and characteristics of each chapters.

The purpose of this paper is forcasting of flooding area using LiDAR surveying data, and flood map for damage prevention is established for this purpose. Teahwa river at Ulsan city was chosen as test area and the flood simulation was produced in this area. For the flood simulation, each DEM using LiDAR data and digital map was established and then HEC model program and MIKE program was used to decide the amount of flood flowing and flood height. To improve the rainfall-overflow simulation confidence using inspection comparison of LiDAR data this paper analyzed and compared the LiDAR DEM accuracy and 1/5000 digital map DEM. The height accuracy is important factor to make flood map, however, LiDAR survey execution of all river area is not economic so, LiDAR survey execution of only important area is possible to be make high accuracy and economic flood map. The expectation effect of flood simulation is flood damage prevention and economic savings of recovery cost by forcasting of rainfall-overflow area and establishment of counter-measure.
