  • As consumption of high-quality fruits increases and sales and packaging units become smaller, the demand for automatic fruit grading systems is increasing. Compared to other crops, the quality of fruit is determined by visual characteristics such as shape, color, and scratches, rather than just physical size and weight. Accordingly, this study presents a CNN model that can effectively extract and classify the visual features of fruits and a perceptron that classifies fruits using physical features, and proposes a stacking ensemble model that can effectively combine the classification results of these two neural networks. The experiments with AI Hub public data show that the stacking ensemble model is effective for grading fruits. However, the ensemble model does not always improve the performance of classifying all the fruit grading. So, it is necessary to adapt the model according to the kind of fruit.

  • This study analyzes the place of modem architecture based on the place theory of C. N, Schultz. For applying Schultz's theory to the modern architecture, It is required to examine the modern cityscape, features of inner space of architecture and features of program. By analyzing the avant-garde architecture of Rem Koolhaas on such basis, the potentiality of placeness of modern architecture could be verified and the alternatives would be searched. It is inferred that the placeness features of Rem Koolhaas' public architecture is under the influence of the interpretation of program based on the humane background rather than the physical aspects of surroundings. The inner space shows the non-linear features, the metaphor of city. The obscurity of physical boundary illustrates the flexible features with ambiguous boundary. Consequently, the inner space expresses the surreal atmosphere that doesn't match the purposes of usage of architecture, the traditional concept. The outer shape is recognized as the by-product from the interpretation of internal program rather than it considered the surrounding context. The outer shape has the relatively simple formative shape and contrasts against the complicated inner space by using the non-physical materials. It is found that Koolhaas' architecture doesn't pursue the features of placeness of traditional concept. However, It is inferred that his architecture has the possibility of placeness by attaching the meaning through the social roles of each architecture. It gives the substantial suggestion to the modern architecture that can't easily acquire the placeness of traditional concept due to the environment of modern city.

  • Just as it is possible to distinguish people by using physical features, such as fingerprints, irises, veins, and faces, and behavioral features, such as voice, gait, keyboard input pattern, and signatures, the an IoT device includes various features that cannot be replicated. For example, there are differences in the physical structure of the chip, differences in computation time of the devices or circuits, differences in residual data when the SDRAM is turned on and off, and minute differences in sensor sensing results. Because of these differences, Sensor data can be collected and analyzed, based on these differences, to identify features that can classify the sensors and define them as sensor-based device DNA technology. As Similar to the biometrics, such as human fingerprints and irises, can be authenticatedused for authentication, sensor-based device DNA can be used to authenticate sensors and generate cryptographic keys that can be used for security.

  • Eurasian eagle owl (Bubo bubo kiautschensis) is a natural monument (No. 324) and is also classified as an endangered wildlife grade II the Ministry of Environment of Korea. Eurasian eagle owl is threatened by the human being. But the efficient rescue and treatment for Eurasian eagle owl are still problematic, due to lack of basic data. In this study, to obtain basic resources for establishing more efficient rescue system, we held a physical examination and measured size physical part. In addition, we analyzed blood sample and feces samples and autopsy. We conduct the physical examination with measuring tapes and scales for 16 live features and 11 dead features. After inhalation anesthesia take the blood samples from wing vein. Blood samples are analyzed in hematologic and chemistric methods. We collected the feces through individual floor of cages from 12 live features and conducted the feces analysis. Autopsy was conducted for 11 dead samples. In physical examination, the mean body weight and total length of live features was 2.26${\pm}$0.35kg, 61${\pm}$2.38cm, the mean body weight and total length of dead features was 1.57${\pm}$0.51kg, 59.31${\pm}$3.51cm. Mean PCV was 46.57${\pm}$4.97%, while mean TPP was 3.49${\pm}$0.57g/dL. In feces sample analysis, 9 of 12 owls(75%) were infested by gastrointestinal helminths. The infection rates were: Trematoda (41.7%), Capilaria sp.(66.7%), acanthocephalans (25%). In autopsy, we confirmed 11 features were infested by duplicated infection of more than 2 helminths. Result of this study will be used for establishing reference range for physical features, blood analysis in Eurasian eagle owl. Therefore, to obtain basic resources for establishing more efficient rescue system, we have to make long-term conservation plans for Eurasian eagle owl.

  • From the findings of an exploratory study describing the living environments of segregated Alzheimer/Dementia Units (ADUs), the results relative to environmental cueing reatures, reality orientation aids, and communication/noise control methods are highlighted. Data were collected from a nonrandom, purposive sample of 99 ADUs and their parent long term care facilities in 34 states. Specific recommendations are made about physical features that may assist confused and disoriented residents and contribute to way-finding and orientation in specialized dementia units.

  • Bertolotti's syndrome (BS) is a disease that should be differentiated from low back pain (LBP) in young patients. BS shows an anatomical abnormality in which elongated transverse processes of the last lumbar vertebra articulate or fuse with varying degrees to the sacrum or ilium according to radiologic findings, which is associated with the clinical feature of LBP or radiating pain. In this case report, we describe various clinical features such as a waddling gait with severe foot and triceps surae muscle pain, in addition to the typical symptom of BS such as LBP. We report the various clinical symptoms and treatment progress in this case and review the literature.

  • In order to study the development of partial discharge (PD) under typical protrusion defects in gas-insulated switchgear, we applied step voltages on the defect and obtained the ${\varphi}-u$ and ${\varphi}-n$ spectrograms of ultra-high frequency (UHF) PD signals in various PD stages. Furthermore, we extracted seven kinds of features to characterize the degree of deterioration of insulation and analyzed their values, variation trends, and change rates. These characteristics were inconsistent with the development of PD. Hence, the differences of these features could describe the severity of PD. In addition, these characteristics could provide integrated characteristics regarding PD development and improve the reliability of PD severity assessment because these characteristics were extracted from different angles. To explain the variation laws of these seven kinds of parameters, we analyzed the relevant physical mechanism by considering the microphysical process of PD formation and development as well as the distortion effect generated by the space charges on the initial field. The relevant physical mechanism effectively allocated PD severity among these features for assessment, and the effectiveness and reliability of using these features to assess PD severity were proved by testing a large number of PD samples.
