  • The morphological properties of various structure materials of domestic and foreign reconstituted tobacco products(RTP) were investigated by using the Bauer-McNett classifier and the image analyzer. The results of the fiber classification showed the fraction of the bigger size structure materials was larger in a domestic RTP than that in two foreign RTPs. In case of fine fraction, the domestic RTP had bigger fine fraction than two foreign RTPs. Images of each structure materials showed the scrap in the foreign RTPs kept the original shape which were rare in the domestic RTP fractions. Those results deduced that the raw materials in a foreign RTP process might be treated separately depending on the mechanical and morphological properties, which could reduce the amount of fine generation and increase the efficiency in raw material treatment.

  • The lodgement of foreign material in the larynx is potentially life thereatening as complete obstruction of this region does not leave the individual with a viable airway. In the literature review, laryngeal foreign bodies accounted for about $3\%$ of the whole foreign bodies in the air passage. This report describes a rare case of laryngeal obstruction by subglottic foreign body(tooth) occurred during tooth extraction, in which repeated Heimlich maneuver failed to expel the foreign body and aggravated airway obstruction.

  • Residual foreign objects at the secondary side (top of the tubesheet and tube support plates) of a steam generator are likely to cause a leak by causing wear in the tube. The extent of wear is significantly affected by the material, shape, and size of the foreign object, and the corrosion properties of the tube. The presence of foreign objects at the top of the tubesheet and tube support plates has been identified using remote visual inspection methods such as the foreign object search and retrieval and eddy current test (ECT). The detection of the residual foreign object at the secondary side of a steam generator has limitations that depend on the material properties and the condition of contact with the tube. In this study, which is vertical and horizontal from the upper tubesheet, the corresponding bobbin ECT signals were collected and analyzed to measure its ability to detect foreign objects.

  • Ileovesical fistula is a rare condition in children. A case of 13 year-old female with ileovesical fistula caused by an ingested foreign material is presented. She had dysuria and lower abdominal pain for one month. There was no history of medico-surgical illness such as Crohn's disease or diverticulitis. Preoperative imaging study showed a movable calcified object in the pelvic cavity and air bubbles in the bladder. At laparotomy a bezoar-like mass was found at the antimesenteric border of the terminal ileum adherent to the dome of bladder. Segmental resection of the ileum and partial cystectomy were performed.

  • The Korea food service industry, in its external shape, is growing explosively, along with the foreign brand's great influx. The domestic food service industry is loosing the competition against the foreign due to its poor development in human resources, marketing techniques and the menu. To actively compete with the foreign brands that runs with the developed management skills and enough fund, the domestic should classify the customers first and develop the menu. Also classified customers need diverse atmospheres to be satisfied. In addition to improve and specialize the quality of the service, there must be enough education for sure. Introducing foreign brands toward the domestic market doesn't help. In here, it is too crowded. We must try the international market with revised traditional and even foreign foods. The government needs to develop more effective and material polices, at the same time they abolish legal and systematic regulation.

  • Retained wooden foreign bodies following penetrating trauma are a difficult diagnostic problem. However, penetrating wooden foreign bodies of head and neck have the potential for misinterpretation or failure to detect such foreign bodies on CT. Given the likelihood that such a miss will result in an abscess or neurovascular injury, we present the method with higher window settings, they had a higher attenuation with a unique striated internal architecture and different Hounsfield numbers readily differentiate air and non-air hypodense material such as fat, or possibly wood. Being aware of the potential appearance of wood, we may also find CT useful in excluding small retained fragments in postoperative patients with persistent symptoms. This article presents two cases in which wooden foreign bodies of head and neck were present with CT evaluation.

  • The PTP (Press-Through-Pack) has been widely used as a packing material for tablets and capsules. But esophageal foreign bodies attributed to the PTP may cause injury to esophageal mucous membrane, potentially inducing severe complications such as hemorrhage, perforation, etc. We report three cases of PTP foreign bodies in esophagus with reference to recent literature.

  • The neoclassical economic supporters have suggested that foreign direct investment and raw material (e.g., coal, electricity, gas, and oil) are critical economic growth inputs. Few previous studies have analyzed the relationship between foreign direct investment and energy consumption on economic growth. However, existing studies usually have applied the frequentist inference. The limitation of the frequentist inference is that, if the coefficient of the independent variable is not yet significant, then conclusions might be unreliable. By applying the Bayesian approach, the main aim of this study is to revisit the impact of foreign direct investment, electricity consumption, and urbanization on economic growth in six ASEAN countries from 1980 to 2016. The obtained outcome shows that the impact of electricity consumption is evident and positive on economic growth in both frequentist and Bayesian inferences. However, the influence of foreign direct investment is not identified by frequentist inference, while Bayesian inference provides evidence that foreign direct investment is a moderately positive impact on economic growth. The empirical result from Bayesian inference contributes to the literature on foreign direct investment modeling and could be of significant importance for a more efficient foreign direct investment attracting and achieve sustainability in the long-term.

  • OBJECTIVE : To study the management (diagnostic and therapeutic) of esophageal foreign bodies with rigid esophagoscopy. MATERIAL AND METHODS : All 100 patients admitted to the Dankook University Hospital for ingestion of foreign bodies between May 1994 and July 1999. The outcome for each patient was determined by examining hospital records of demographic information, identification of the foreign body and the removal procedure used. RESULTS : Rigid esophagoscopy was performed for suspected foreign bodies in 100 cases an impacted. The most frequent location was the upper third of the esophagus (68%). The most common type of foreign body was fish bones in adult(61%) and coins in children(70%). In 12 patients. flexible endoscopy had failed previously to remove the foreign body and 4 cases were migrated esophageal metal stent in esophageal stenosis. CONCLUSIONS : The rigid esophagoscopy is appropriate techniques for managing esophageal foreign bodies.

  • When materials such as metal are into the secondary side of steam generator, they, so called foreign objects, may have influences on the integrity of the steam generator tubes. They cause the tube wear due to the relative motion between the tubes and foreign objects and the tube impact due to flow. The best way to avoid the effects is to remove all the foreign objects. However, it is not easy to remove the foreign materials thoroughly due to their condition such as the location. Considering the wear and impact by the foreign materials, KEPRI(Korea Electric Power Research Institute) developed the methodology to evaluate the foreign materials analytically. This methodology was described with a computer program in order to obtain the fast results. The program informs whether the tubes have the structural integrity when the foreign material strikes the tubes. Moreover, this gives us the remaining life of the steam generator tubes. In this paper, the program, which evaluates the effects of the foreign objects in the secondary side of steam generator, is introduced.
