In a dynamic environment autonomous robots often encounter unexpected situations that the robots have to deal with in order to continue proceeding their mission. We propose an adaptive goal-based model that allows cyber-physical systems (CPS) to update their environmental model and helps them analyze for attainment of their goals from current state using the updated environmental model and its capabilities. Information exchange approach utilizes Human-Agent-Robot-Machine-Sensor (HARMS) model to exchange messages between CPS. Model validation method uses NuSMV, which is one of Model Checking tools, to check whether the system can continue its mission toward the goal in the given environment. We explain a practical set up of the model in a situation in which homogeneous robots that has the same capability work in the same environment.

Coarctation of the aorta, a well known congenital cardiovascular defect, can be recognized in most instances by simple findings of physical examination. This condition shortens life if untreated, but it can be corrected surgically to render the patient functionally normal. It seems relatively rare in Asian. We experienced two cases of coarctation of the aorta which were treated surgically. The first case was 17 years old male with juxtaductal type of coarctation of the aorta. The second was 7 years old female with preductal type of coarctation of the aorta and combined anomaly of PDA and she had been in congestive heart failure. In both cases, coarctated segments of the aorta were resected and end to end anastomosis were performed. In the second case, PDA was closed by division before resection of the coarctated segment. The postoperative courses were uneventful. They discharged 2 weeks postoperatively without any complications. Blood pressure was nearly normalized at the time of follow up check.

Gallbladder injuries are rare in cases of blunt abdominal trauma and are usually associated with damage to other internal organs. If the physician does not suspect gallbladder injury and check imaging studies carefully, it may be difficult to distinguish a gallbladder injury from gallbladder stone, hematoma, or bleeding. Therefore, in order not to miss the diagnosis, the clinical findings and correlation should be confirmed. In the present case, a 60-year-old male presented to a local trauma center complaining of pain in the upper right quadrant and chest wall following a motor vehicle collision. Abdominal computed tomography (CT) showed a hepatic laceration and hematoma in the parenchyma in segments 4, 5, and 6 and active bleeding in the lumen of the gallbladder. Traumatic gallbladder injuries generally require surgery, but in this case, non-operative management was possible with cautious follow-up consisting of abdominal CT and angiography with repeated physical examinations and hemodynamic monitoring in the intensive care unit.

On March 6 2021, Apophis made a close approach to the Earth with a minimum distance of 0.11 AU when the apparent magnitude reached up to V~16. This was the most favorable condition to observe this asteroid until its 2029 encounter. The observations during this apparition were extremely important to determine major physical properties, such as size, rotational state, 3D shape model, surface mineral properties. So, we organized the observation campaign during the 2021 apparition. The main goals of our campaign are to refine the spin state and 3D shape model and check the surface composition variations. The campaign involved dozens of countries and included ground-based photometry and spectroscopy, and spacecraft observations. Our timely observation campaign will provide essential data in planning the operation scenario for the space mission. In this presentation, we will report the preliminary result of the Apophis observation campaign during the 2021 apparition.

Documented quality control plays a vital role I the production of technical “Depth filter” sheets used in industries such as Beverage and pharmaceutical. Depth filter sheets which can be up to several millimeters thick are stacker in plate and frame filter systems. They are the core of stainless steel filter systems which can be up to several meters high. FT-NIR Spectroscopy has many potential applications in the whole production line of filter sheets. Raw materials such as different types of cellulose pads, white powdery fillers (e.g. Kieelgur, Perlite) or liquid chemicals such as wet-strength agents we, with the help of NIR, easy to identify. NIR can also determine physical parameters such as particle size, essential for the filtration behavior. FT-NIR can be used for the quality parameters of the final product. Moisture and permeability can be determined, and with the help of the speed of this NIR method it is possible to correct possible faults quickly in the production process. Waste production can be minimized which is good for both the product profitability and the environment. Further tests have shown that it is also possible to use NIR on-line in the production area, to check the concentrations and the homogeneity of the paper suspension consisting of cellulose fibres, fillers and additives.

Homeopathic Pulsatilla 30C was evaluated in 4 clinical cases of ophthalmic complications with concomitant separation anxiety in dogs. Separation anxiety in dogs is excessive anxiety regarding to the separation from owners and is one of the most common behavioral problems in dog. In addition, ocular diseases is sometimes related with abnormal behaviors. Holistic approach is good alternative method to treat dogs with physical problem associated behavior problem. Homeopathy is one of the complementary and alternative medicines and bases on healing of patients themselves which includes mind healing, not the disease itself. Among the material medical remedy of homeopathy, the Pulsatilla is used as homeopathic remedy for ocular problems, earache, cough, cold, and anxiety from lost attention. These case studies described the successful treatment of ocular diseases and separation anxiety by application of Pulsatilla 30C as homeopathy in 4 dogs. During the homeopathy, these dogs did not receive any other treatments, and were performed the physical exam to check the ocular problems. These dogs were completely cured of physical and behavior problem within 10 days. On following up, any clinical signs were not observed at one month after the last therapy. In addition, as from the treatment the anxiety problem of patients has been much better improved. According to these case studies, we know that an application of homeopathic remedy may be useful therapeutic choice to treat both problems of physical and behavior.

The purpose of this study was to identify the needs which were perceived by patients who were received spinal anesthesia for surgery. The subjects consisted of 50 adult patients who were admitted to 2 university hospitals and 2 general hospitals in Pusan city and 1 general hospital in Koje City for surgery under spinal anesthesia. Thirty eight percent of subjects received information about anesthesia before the operation. The instrument for this study was developed by the researcher based on literature and a pretest. Data were collected from December 10, 1999 to February 10, 2000 and were analyzed by content analysis. The results were that there were 533 meaningful statements in the needs of spinal anesthesia patients. The needs of spinal anesthesia patients had 51 items (preoperation (6), induction of anesthesia(5), intraoperation (27), postoperation(13)) and 6 categories (information, emotional welfare, physical welfare, post anesthetic management, control of physical environment, humane treatment). From the results, it can be concluded that: 1. In the pre-operation period, we have to explain anesthesia procedures, adequate position of anesthesia, duration before anesthesia wears off and sensation of paralysis. We have to supply emotional support to relieve anxiety because of anesthesia. 2. In induction of anesthesia, we have to support patient's position for anesthesia, and relieve anxiety so that patients participate in induction of anesthesia well. 3. In intra-operative period, we have to check the level of anesthesia, and keep up a comfortable position for operation and care for physical discomfort such as thirst, nausea, vomiting, dyspnea and to maintain body temperature of the patient. Since the patient is conscious, we have to communicate with the patient to relieve anxiety, maintain privacy, inform the patient of the process of the operation and encourage the surgeon to explain the outcome of the operation. The operating team needs the careful about what they say and to place the instrument well. We have to ventilate the room air and reduce noise. 4. In the post-operative period, we have to explain the purpose and duration of bed rest, complications of anesthesia and care for physical discomfort such as pain, dysuria, headache, backache. Also we have to maintain body temperature of the patient and maintain privacy.
