  • A method for detecting foreign substances in mould based on scatter grams was presented to protect moulds automatically during moulding production. This paper proposes a wavelet transform foreign detection method based on Monte Carlo analysis mechanism to identify foreign objects in the tube. We use the Monte Carlo method to evaluate the image, and obtain the width of the confidence interval by the deviation statistical gray histogram to divide the image type. In order to stabilize the performance of the algorithm, the high-frequency image and the low-frequency image are respectively drawn. By analyzing the position distribution of the pixel gray in the two images, the suspected foreign object region is obtained. The experiments demonstrate the effectiveness of our approach by evaluating the labeled data.

  • This paper presents a unified account of three kinds of constructions in which more than one NP can show up with the same case in simple sentences in Japanese and Korean: double subject, double nominative object and double accusative constructions. Noting that the second NPs in these constructions are functional or relational, this paper proposes to assign them the category and type different from the first NPs. We show the derivations of these three constructions in a parallel manner, and explain the asymmetries in extractability between possessor and possessed NPs in relativization.

  • The purpose of this paper is to review the importance of situated cognition and the features of MOO(Multi-user Object Oriented)environments for effective foreign language learning. Learning foreign languages is beyond simply recalling for the vocabularies or expression usages of targeted languages. As much the same as children naturally acquire their mother languages among active and social interactions with other surrounding people, foreign languages should be told in the circumstances and contexts for authentic applications of foreign languages. The MOO, one of the virtual realities with spatial metaphors on the text basis, has been gaining high attentions from educational fields, thanks to the strong functions of social contexts and learner interactions. This paper approaches the features of MOO as foreign language learning environments, in terms of activity, context and interaction.

  • In Korea, cases of direct insertion of foreign bodies into the rectum are rare in the literature. Most cases of rectal insertion of foreign bodies are associated with sexual acts and psychiatric disorder such as schizophrenia. Objects inserted into the anus are usually blunt and shaped like the male genitalia. The removal method can be varied depending on the size and shape of the foreign object, its anatomical location, and the accompanying complications. In cases wherein attempts to remove the object fail or there are rectal perforation and peritonitis complications, immediate laparotomy may be required in order to prevent serious complications such as sepsis. Here, we report on a case of rectal perforation and peritonitis due to insertion of a foreign body in a middle-aged patient, with a literature review. He inserted a sharp pig backbone in his rectum and he only had depression. The patient underwent a Hartmann's operation as well as psychiatric counseling and treatment. Thus, after removal of foreign bodies, psychiatric counseling and treatment should be carried out in order to prevent similar accidents and to minimize the need for trauma medicine.

  • Penetrating neck injuries constitute 5-10% of all trauma cases. These injuries may cause life-threatening suppurative or vascular complications, but the severity and extent of damage depends upon the inflicting object and the involved structures. If significant complications are not expected, then it is best to leave the foreign body embedded and avoid surgical risks. We present a rare case of a foreign body embedded in the neck causing tinnitus and foreign body sensation.

  • We report the case of a seven-year-old boy with an ingested foreign body, which was retained within the appendix for a known duration of ten months, ultimately requiring appendectomy. The ingested foreign body was incidentally discovered by abdominal x-ray at an emergency room visit for constipation. Despite four bowel cleanouts, subsequent x-rays showed persistence of the foreign body in the right lower quadrant. While the patient did not have signs or symptoms of acute appendicitis, laparoscopic appendectomy was performed due to the risk of this foreign body causing appendicitis in the future. A small metallic object was found within the appendix upon removal. This case highlights the unique challenge presented by foreign body ingestions in non-verbal or developmentally challenged children and the importance of further diagnostic workup when concerns arise for potential retained foreign bodies.

  • A foreign body in the airway can be a potentially life-threatening event. The diagnosis and treatment of foreign bodies in the airway are a challenge for otolaryngologists. Despite the improvements in medical care and public awareness, approximately 3,000 deaths occur each year from foreign body aspiration. A high degree of vigilance is required to ensure prompt treatment and avoid the complications of foreign body aspiration. The author encountered a case of a 77-year-old female patient who had aspirated an unknown foreign body that was fixed in her main bronchus. An initial attempt was made to remove it with a flexible bronchoscope but failed due to the patient's hypoxemic state during the procedure. Under general anesthesia, a rigid bronchoscopic examination was performed, but it was difficult to approach the object due to the bronchus curvature. Instead, a cryotherapy instrument of bronchoscopy was applied. The foreign body was frozen and removed to the carina, where a laryngoscope and laryngeal forceps were used to remove it.

  • Rapid change of the era has caused change to consumption. New concept of consumer means not consumer who is simply provided a product, but a consumer who lays emphasis on value. That is to say, it indicates a consumer who values both on service and information as well as a product itself when they purchase. Therefore, the purpose of this research is to analyze the changes of POPs and objets at domestic and foreign fashion lingerie shops in different periods, and to encourage the effective introduction of POPs and objets for display at fashion lingerie shops in the future. I have used 100 pictures of 6 domestic brands and 80 of 6 foreign brands to analyze, and the periods were divided into 2000-2003, 2004-2007, and after 2008. The result of analyzing is as follows. First, give much information and great satisfaction to customers through the various types of POP, which convey the image and the concept of the products. If current POP was used only for sales, there ! should be various kinds and types of POPs to present not only basic information of products but also the value beyond it. Second, advance the products value by the presentation of diverse object. Furniture, fixtures, Lighting, Gift Box, Poster and mannequins should be used not to show simple props and presentation of product in the past, but to show brand images and Design concept of products.

  • In this paper, the effects of temperature change on the impact of CFRP laminates was experimentally studied. Composite laminates used for this experiment are CFRP orthotropic laminated plates, which have two-interfaces$[0_6^{\circ}/90_7^{\circ}]_s$ and four-interfaces$[0_3^{\circ}/90_6^{\circ}/0_3^{\circ}]_s$. The interrelations between the impact energy vs. delamination area, the impact energy vs. residual bending strength, and the interlayer delamination area vs. the decrease of the residual flexural strength of carbon fiber epoxy composite laminates subjected to FOD(Foreign Object Damage) under high temperatures were experimentally observed.

  • In this paper, we propose an efficient image segmentation technique for large-sized monochrome images using a hybrid approach which combines threshold and region-based techniques. First, an image is partitioned into fixed-size blocks and for each block the representative intensity is determined by averaging pixel intensities within the block. Next, the neighborhood blocks that have similar characteristics with respect to a specific threshold are merged in order to form candidate regions. Finally, those candidate regions are refined to get final target object regions by merging regions considering the spatial locality and certain criteria. We have performed experiments on images selected from various domains and showed that our technique was able to extract target object regions appropriately from most images.
