Blacken spoilage is one of the common problems during the cold storage of dried persimmon in Korea. We collected the spoiled dried persimmon in the refrigerator and classified them to 4 types depending on their appearances. Furthermore we isolated blacken spoilage inducing bacteria from type D of dried persimmons. Among the isolates we identified the seven blacken spoilage inducing bacteria. They are Aeromonas hydrophila DP1, Cedecea davisae DP2, Ewingella americana DP3, Flavimonas oryzihabitans DP4, Providencia rettgeri DP5, Providencia rustigianii DP6 and Serratia plymuthica DP7. Strains were identified based on their morphological, cultural and physiological properties. We also found that Ewingella americana DP3, Flavimonas oryzihabitans DP4 were the major blacken spoilage inducing bacteria during dried persimmon storage.

Most of fruit quality classification has been done by time consuming, inaccurate and intensive manual labor. This study proposed an automated fruit grading system based on appearances and internal flavors. In this study, image processing technique and a weight checker were used to measure the value of appearance features and the near infrared spectroscopy analysis method was used to estimate the value of internal flavors. Additionally, I suggested 8x8x5x5 ANN based fruit quality classifier model to grade fruits quality. The proposed automated fruit quality classification system is expected to be very beneficial for many farms where heavy manual labor is usually needed for fruit quality classification.

Object detection and tracking is an exciting and interesting research area in the field of computer vision, and its technologies have been widely used in various application systems such as surveillance, military, and augmented reality. This paper proposes and implements a novel and more robust object recognition and tracking system to localize and track multiple objects from input images, which estimates target state using the likelihoods obtained from multiple CNNs. As the experimental result, the proposed algorithm is effective to handle multi-modal target appearances and other exceptions.

Pedestrian tracking is a particular object tracking problem and an important component in various vision-based applications, such as autonomous cars and surveillance systems. Following several years of development, pedestrian tracking in videos remains challenging, owing to the diversity of object appearances and surrounding environments. In this research, we proposed a tracking-by-detection system for pedestrian tracking, which incorporates a convolutional neural network (CNN) and color information. Pedestrians in video frames are localized using a CNN-based algorithm, and then detected pedestrians are assigned to their corresponding tracklets based on similarities between color distributions. The experimental results show that our system is able to overcome various difficulties to produce highly accurate tracking results.

We report a rare case of arachnoid granulations mimicking multiple osteolytic bone lesions. A 66-year-old woman was admitted to a local clinic for a regular checkup. Upon admission, brain CT showed multiple osteolytic lesions in the occipital bone. These needed to be differentiated from multiple osteolytic bone tumor. Subsequent brain MRI revealed that the osteolytic lesions were isointense to cerebrospinal fluid, hyperintense on T2-weighted image, hypointense on T1-weighted image, and with subtle capsules around the osteolytic lesions that were visible after gadolinium injection. A bone scan revealed no radiotracer uptake. The lesions were in both the transverse sinuses and the torcular herophili. With typical radiological appearances of the lesions, the osteolytic lesions were diagnosed as multiple arachnoid granulations. No further treatment was planned. A 1-year follow-up brain CT scan revealed no change. We should consider the possibility of arachnoid granulations when multiple osteolytic lesions are observed in the occipital bone.

Detecting partially occluded objects is difficult due to the appearances and shapes of occluders are highly variable. These variabilities lead to challenges of localizing accurate bounding box or classifying objects with visible object parts. To address these problems, we propose a two-stage part-based attention approach for robust object detection under partial occlusion. First, our part attention network(PAN) captures the important object parts and then it is used to generate weighted object features. Based on the weighted features, the re-weighted object features are produced by our reinforced PAN(RPAN). Experiments are performed on our collected military vehicle dataset and synthetic occlusion dataset. Our method outperforms the baselines and demonstrates the robustness of detecting objects under partial occlusion.

Today's Eastern philosophers try to use the formal logic organized by Aristotle, saying that there was no logic in the East. This researcher found that Confucius and other Asians used Che-Yong logic. The Che-Yong logic is based on the Che-Yong law, which is a natural law. The Che-Yong law consists of the Che-Yong principle and the Hyeon-Mi principle. The Hyeon-Mi principle is that if there is an appearance on the outside, there is a corresponding cause in it. The Che-Yong principle is that the highest common cause of various appearances is Che, and the Che grows and changes on its own to become a Yong. Identifying Che and predicting Yong is Che-Yong logic. Here, I'd like to introduce Che-Yong logic and suggest a new research methodology to apply it.

In pediatric thoracic CT, respiratory motion is generally treated as a motion artifact degrading the image quality. Conversely, respiratory motion in the thorax can be used to answer important clinical questions, that cannot be assessed adequately via conventional static thoracic CT, by utilizing four-dimensional (4D) CT. However, clinical experiences of 4D thoracic CT are quite limited. In order to use 4D thoracic CT properly, imagers should understand imaging techniques, radiation dose optimization methods, and normal as well as typical abnormal imaging appearances. In this article, the imaging techniques of pediatric thoracic 4D CT are reviewed with an emphasis on radiation dose. In addition, several clinical applications of pediatric 4D thoracic CT are addressed in various thoracic functional abnormalities, including upper airway obstruction, tracheobronchomalacia, pulmonary air trapping, abnormal diaphragmatic motion, and tumor invasion. One may further explore the clinical usefulness of 4D thoracic CT in free-breathing children, which can enrich one's clinical practice.

본 연구는 학생과 학부모의 의복태도를 중심으로 여교사의 외모관리가 역할수행(학습지도, 생활지도, 인간관계형성, 학급경영)능력에 미치는 효과를 파악하고자 하였다. 이를 위해 광주광역시에 소재한 중 고등학생 및 학부모 398명으로부터 자료를 수집하여, 요인분석, 군집분석, ANOVA와 Duncan-test, t-test, 기술통계를 이용하여 분석한 결과를 통해 다음과 같은 결론을 얻을 수 있었다. 첫째, 여교사의 역할수행능력 평가는 4요인으로 설명할 수 있었으며 학습지도능력, 생활지도능력, 인간관계능력, 학급경영능력으로 명명하였다. 그리고 학생과 학부모의 의복태도는 개성추구, 유행관심, 의복 중요성, 정숙성 요인으로 명명하였고 이 요인들에 의해 의복태도 유형은, 의복중시 지향집단, 유행 개성 지향집단, 정숙성지향 집단으로 분류하였다. 둘째, 학생의 경우 유행 개성 지향 집단이 여교사의 학습지도능력, 인간관계능력에서 여교사의 외모가 유의한 영향을 미친다고 평가하는 것으로 나타났다. 따라서 여교사는 학생의 의복태도를 잘 파악하고 역할수행에 맞는 옷차림 및 외모관리로 효율적인 역할수행을 할 필요가 있을 것이다. 또한 학부모의 경우 의복태도에 따른 여교사가 역할수행능력 평가에 있어 관련성이 적거나 관련이 있더라도 학습 지도 역할을 할 때 보통 정도의 영향을 미친다고 생각하므로 여교사는 학습지도를 할 때 외모관리에 더욱 관심을 기울여야 할 것으로 사료된다. 셋째, 학생과 학부모의 여교사 옷차림에 대한 관심도는 여교사의 외모에 따른 역할수행능력평가에 영향을 미치므로 여교사 옷차림에 대한 관심도가 높은 학생집단의 지도시에 여교사는 학습지도활동 및 인간관계형성, 학급경영활동을 하는데 있어 여교사 본인의 외모에 신경을 쓸 필요가 있을 것이다. 이상과 같이 학생과 학부모는 자신의 의복태도에 따라 여교사의 외모가 역할수행능력에 영향을 미치고 있다고 평가하고 있음이 확인되었다.다. 학생들의 가치관이 다양화되고 있는 만큼 의생활에 흥미와 관심과 의욕을 가질 수 있도록 충실한 의생활교육이 요구되는 시대에 맞게, 내용은 물론 수업체제를 발전시키는 것이 큰 과제라고 할 수 있다. 이렇게 변화하는 사회, 생활에 학교교육이 발맞춰 나가기 위해서는 교육과정의 틀을 바꾸는 것은 쉬운 일이 아니므로, 교과서의 내용을 교육과정 개정주기보다 자주 정기적으로 개편하여 내용을 수정, 보완할 수 있도록 그 방법을 모색해야 할 것이다.1{\pm}10.8%$, 여자 $54.6{\pm}9.9%$로 조사되었다. 칼슘의 섭취량은 평균필요량에 비해 전체 $74.9{\pm}31.9%$로 나타났다. 에너지 섭취량에 있어서 남자 노인들은 모두가 필요추정량의 75% 미만을 섭취하고 있었고 여자 노인의 경우에도 97%가 필요추정량의 75% 미만을 섭취하여 에너지 섭취량이 매우 낮았다 반면에 단백질 섭취량에 있어서는 남자 노인의 경우 100%가 평균필요량의 125%를 초과하였고, 여자 노인의 경우에는 91%가 평균필요량의 125%를 초과하여 대조적이었다. 비타민 A와 E는 각각 평균필요량과 충분섭취량의 125%를 초과하는 비율이 높게 나타난 반면에 비타민 $B_2$는 특히 남자 노인에서 평균필요량의 75%미만을 섭취한 비율이 높게 나타났다. 엽산 섭취량에 있어서는 평균필요량의 75% 미만을 섭취한 비율이 전체 96%로 나타나 심각한 부족상태로 조사되었다 반면에 철의 섭취량은 남녀 모두 100%가 평균필요량의 125%를 초과하여 섭취한 것으로 나타났다. 아연의 섭취량은 남자 17%,여자 15%가 평균필요량의 75% 미만을 섭취한 것으로 조사되었다. 에너지와 엽산은 모든 노인들에서 평균필요량에 미달되게 섭취한 것으로 나타났다. 반면에 단백질과 철분은 남녀 노인 모두에서 평균필요량 보다 적게 섭취한 대상자가 없는 것으로
