The term "Collaborative medical care" commonly used in South Korea refers to the case where doctors from different medical departments work together to treat a patient within the same medical institution. Therefore, "Collaborative medical care" represents the aspect of a medical team where various medical professionals collaborate based on their expertise to treat patients. Additionally, doctors from different specialties within the medical team engage in horizontal division of labor at an equal status, distributing legal responsibilities according to the principles of division of labor. The Supreme Court also acknowledges cases where multiple doctors collectively provide medical treatment through division of labor or collaboration and states that the doctor who initially attended to the patient must accurately inform the subsequent attending doctor about the patient's condition to enable appropriate measures. In medical institutions with multiple specialties, when doctors from different specialties collaborate to provide medical treatment, the doctor who attended to the patient initially must decide whether collaboration is necessary based on the patient's condition. Subsequently, they must inform the doctor from the relevant specialty about the patient's condition accurately to facilitate appropriate actions. The successor doctor who participates in collaborative medical care must actively communicate relevant treatment information related to the patient's condition with the predecessor doctor who requested collaboration, exchange opinions, and do so until the patient's treatment concludes. However, the determination of the necessity of collaborative medical care should be based on the patient's condition at the time, and it cannot be asserted that collaborative medical care is mandatory in all cases. Whether there is negligence in the decision about the necessity of collaboration will be assessed based on the legal principles of a doctor's duty of medical care.

In order to check the status of tire wear, a driver or auto mechanic generally checks tires with the naked eyes or with a coin. Those are easy for anyone but make it difficult to obtain precise information. But the result is a measure of mechanic wear out due to subjective judgment. Since we can not give correctly measure the stability of the tire. This may lead to an accident of the operator. Therefore, there is a need for a system checking tires precisely, accurately and easily, while making up for the aforementioned defect. This thesis has implemented a system with the aforementioned function. This system tire surface scanner data unit to determine the tread wear on the car and a storage unit for the data save, And a Web service unit allows the user to easily check the information.

Vision-based autonomous precision landing technology for UAVs requires precise position estimation and landing guidance technology. Also, for safe landing, it must be designed to determine the safety of the landing point against ground obstacles and to guide the landing only when the safety is ensured. In this paper, we proposes vision-based navigation, and algorithms for determining the safety of landing point to perform autonomous precision landings. To perform vision-based navigation, CNN technology is used to detect landing pad and the detection information is used to derive an integrated navigation solution. In addition, design and apply Kalman filters to improve position estimation performance. In order to determine the safety of the landing point, we perform the obstacle detection and position estimation in the same manner, and estimate the speed of the obstacle using LSM. The collision or not with the obstacle is determined based on the CPA calculated by using the estimated state of the obstacle. Finally, we perform flight test to verify the proposed algorithm.

원자력 발전소에서 사용되어지는 케이블은 전원 및 제어신호를 안정하게 전달하는 역할을 하며, 비상상태 발생시에는 원자로를 안전하게 shut-down시키는 통로 역할을 하므로 매우 중요하다. 케이블 상태 감시시 절연 및 피복재료는 종류 및 배합내용이 다양하기 때문에 종래의 자료로부터 전선과 케이블의 열화 또는 수명을 추정하기가 극히 어려우며 방사선에 노출이 되는 케이블의 경우 노화현상의 진행이 빠르고 방사선 열화로 수명이 단축되므로 국내 실정을 감안한 독자적인 검증방법 도출, 규제기술 기반 구축 필요 및 규제의 합리화와 효율화 필요성이 대두되고 있다. 기존에 사용해온 케이블 진단 방법에는 절연 파괴 강도 측정을 통한 노화진단, 산화 방지능력 측정을 통한 노화진단, 자켓 및 절연체의 판단, 연신율에 의한 노화진단, 케이블 Indenter에 의한 노화진단, 온도 및 방사선 등의 특정상태에 대한 평가, 유사한 환경조건에 대한 주기적 검토 등이 있다. 기존의 국내외 케이블 상태 감시방법을 조사 연구하므로서 케이블 열화에 대비한 수명관리 규제 기술 및 상태감시 (Condition Monitoring : CM) 기술의 평가 기준을 결정 하고자 한다.

Generally speaking, the internal moisture of concrete is mainly distributed in inner part and concrete surface which is exposed are dned according to influence of temperature and humidity. So, the properties which are compressive strength, modular elasticity, and volume change are different at each part even in same concrete. This is because moisture distribution is changed according to the evaporation and move ment of moisture, exist in the inner porosity of concrete. Therefore, it is necessary that we investigate the properties of concrete according to moisture distribution. The purpose of this study is investigating correlation between the moisture content and mechanical properties in concrete. Compressive and tenslle strength decrease according to increasing moisture content, but modular elas ticity increase. Those increasing or decreasing ratio at drying ratio 100% (absolute dries) is as follows in comparative of drying ratio 0 % (saturated condition).tion).

We tested the capability of the pleasure and arousal dimension-based facial expression synthesis system and proposed the most effective interface for it. First, we tried to confirm the adequateness of the dimensional model as a basic structure of the internal states for the system. Fer it, subjects compared the 17 facial expressions on the two axes. The results validated the fundamental hypothesis of the system. Second, we chose 21 representative expressions from the system to test its performance and had subjects rate their similarities. We analyzed these data using multidimensional scaling methods and these results verified the system's reliability. Third, we compared the efficiencies of two interfaces -coordinate values and slide bars- to find the most suitable interface for the system. Subjects synthesise 25 facial expressions with each interface of it. The results showed that the visualization of two dimensional values into Cartesian coordinate is more stable as an input display of facial expression synthesis system based on dimensions.
