13개월령의 수컷 몰루칸 앵무새가 경미한 식욕부진을 주 증상으로 하여 건국대학교 수의과대학 부속 동물병원에 내원하였다. 신체 검사에서,식도 이물이 소낭 부위에서 촉진 되었다. 흥부 방사선 검사에서 흥부 식도 부위에 위치한 선상의 식도 이물이 확인되었다. 이에 따라 환자는 먹이용 튜브에 의한 식도 이물로 진단되었다. 식도 이물은 내시경과 겸자를 이용하여 다른 부작용 없이 제거되었다. 이 증례 보고는 새에서 내시경을 이용한 효과적인 식도 이물 제거를 보여준다.

Anticarcinogenic activity of astaxanthin-contatining egg yolk(designate AEY) was investigated for mouse ascites carcinogenesis induced by mouse Sarcoma-180(S-180) cells. Female ICR mice(8mice/treatment, 7∼8weeks of age, 25±1g) were injected, i.p. with S-180 cells(1×107cell/ml PBS). Two days later, each mouse was given 0.1ml PBS containing AEY(10, 25 or 50ug/g body weight) or control egg yolk (CEY; 50ug/g body weight) every other day for 7 times. Control mice were only given 0.1ml S-180 cells and 0.1ml PBS. Mice treated with 25ug/g body weight of AEY showed 24.8 days of life, which was equivalent to 138% of control mice's life(180.0 dyas). Based on dose-dependant experiment of AFY, mice treated with 10ug/g body weight showed slightly longer life(19.4 days) relative to mice treated with control mice, and mice treated with 50ug/g body weight exhibited 21.9 days of life. Mice treated with any dose of AEY exhibited longer life than mice with CEY 50ug/g body weight. Body weight of mice treated with AEY was reduced relative to that of control mice CEY-treated mice. These results suggest than AEY inhibits the carcinogenesis of mouse ascites induced by S-180 cells.

This study was conducted to determine the relationship between the body fat percent (BF%) and body mass index (BMI) of Koreans and the differences with Caucasians. Complete data were collected from 3297 subjects (2441females and 856 males) between the ages of 18 and 79. Data were collected between September 2001 and November 2001 in Seoul and Pusan. For the statistical analysis, only the data on subjects between the ages of 18 and 65(3200) were used Body weight and height were measured BMI (kg/$m^2$) was computed From BMI, BF (%) was calculated using age- and sex-specific prediction formulas. BF% was assessed using an INBODY 2.0 body fat analyser. Data analysis showed that the females were significantly younger than the males, were smaller, lighter and had a lower body mass index. Body fat percent of the females was higher than that of the males. 1he differences between actual measured BF% and BF% as predicted from prediction equations from the literature, based on BMI, age and sex, were correlated with level of body fat and age. There is a significant age-related decrease in body fat in Koreans for any given BMI and sex, which is remarkably different compared to age-related increases in body fat in the European reference group. For the same age and BF%, Korean females have a slightly lower BMI than their European counterparts. Korean males have, for the same age and BF%, a higher BMI than their European counterparts. The differences between females and males were not significant. It was concluded that, assuming that the data on body fat percent was correct, that the relationship between BF% and BMI is quite different in Koreans than in European Caucasians. Thus, for younger Koreans cut-off values for obesity should be slightly lower than those for Caucasians whereas for older Koreans the cut-off points for obesity should be higher than those for Caucasians.

A two-layer incompressible time-accurate Euler solver is applied to analyze flow fields around a submerged body moving at a critical speed near a pycnocline. Discontinuities in the dependent variables across the material interface are captured without any dissipation or oscillation using the ghost fluid method on an unstructured grid. It is shown that the material interlace has significant effects on forces acting on a submerged body moving near a pycnocline regardless of the small difference in densities of two layers. Contrary to the shallow water waves, a submerged body can reach a critical speed at very low Froude number due to the small difference in the densities of the two layers.

Laryngeal foreign bodies are not common among the foreign bodies of aerodigestive tract. It is relatively easy to diagnose in acute phase of entry because of a readily\ulcorner available history of intake, and signs or symptoms referable to the foreign body in the highly sensitive air passage. However, on occasion, sudden death by respiratory failure occurs due to complete obstruction of airway. Therefore, it is common and safe to remove the laryngeal foreign bodies by suspension laryngoscope under general anesthesia after tracheostomy. Recently, the authors experienced a case of metallic foreign body in larynx penetrating neck, which was removed by suspension laryngoscope under general anesthesia without any life threatening complication.

In this study, a rigid multi-body dynamic model has been developed for mechatronic analysis to evaluate dynamic behavior of a machine tool. The development environment was the commercialized analysis tool, ADAMS, for rigid multi-body dynamic analysis. A simplified servo control logic was implemented in the tool using its functions in order to negate any external tool of control definition. The advantage of the internal implementation includes convenience of the analysis process by saving time and efforts. Application of this development to a machine tool helps to evaluate its dynamic behavior against feeding its component, to calculate the motor torque, and to optimize parameters of the control logic.

The purpose of this study is to preview artistic presentation, factors of designing and ornamentation, to provide useful information to the wedding dress industry in developing consumer-oriented design of wedding dress. Also, this study is to investigate relativity between individual characteristics, such as demographic character and body figures, and preference of consumers, in order to learn if there is any pattern of consumers decision making, and to help consumers by giving tips for their wedding dress shopping. According to this study, I can see that when modern South-Korean adult women choose their wedding dress, they consider many factors just like silhouette, detail, fabric material and so on, then they select their own best dress by grasping their body characteristics.

The excellent beam quality of high power fiber lasers are commonly used for remote welding applications in body job applications. The Welding speed and productivity is unmatched with any other welding technology including resistance spot welding or traditional laser welding. High tooling cost for clamping and bulky safety enclosures are obstacles which are limiting the use. With the newly developed Laser stitch welding gun we have an integrated clamping in the process tool and the laser welding is shielded in a way that no external enclosure is needed. Operation of this laser welding gun is comparable with resistance spot welding but 2-times faster. Laser stitch welding is faster than spot welding and slower than remote welding. It is a laser welding tool with all the laser benefits like welding of short flanges, weld ability of Ultra High Strength steel, 3 layers welding and Aluminium welding. Together with low energy consumption and minimum operation cost of IPG fiber laser it is a new and sharp tool for economic car body assembly.

On this paper, unimorph type piezoelectric vibrator made by attaching ceramic plates on rectangular elastic body, to find the basic characteristic of the actuators. In experiment, elastic body's displacement and resonance frequency were measured according to changes of ceramic's length and elastic body's length. Also, temperature changes were observed according to time. The displacement and resonance frequency were increased when the ceramic's length were increased. When elastic body's length was increased, the displacement was increased. Also, the temperature was increased according to time, but at some time it was saturated and the temperature was not increased any more.

Despite all preventive efforts, aspiration of foreign body during clinical dental procedures occurs occasionally. Careful clinical physical examination, proper assessment of radiography and prompt emergency treatment can prevent any potentially serious consequences. In this report, we will report serial cases of foreign body in different situation from mild cases to severe cases and suggest some clinical guidelines to dental health care providers.
