The subway with the initial constructive expense which is enormous together is the public transportation means where the many expense is expended in the operation and maintenance civil official. Seoul Metro until initial opening to traffic after present time cannot escape every year deficit to be, the cause is a possibility of seeking from the fare system which is short in transportation prime cost. Currently Seoul Metro is operating with the distance proportional fare system the passenger ticket system which is simple (usual volume, group volume and fixed amount volume, affection renunciation, charge free volume). When the biased characteristic of the user it plans considering from the goods development side for the variety for and a deficit solution, against the fare system systematic it researches and solution plan politically. Financial of the subway operation agency young the investigation against the present condition of the hazard subway fare system which is solved the bud with problem point a fare system from the research which it sees consequently and improvement program under analyzing the man with underdeveloped genital organ. Base on the reporter to analyze the introduction plan which with the character which will reach it follows with the necessity of introduction of the 1st passenger ticket (24 hour volume).

Metastatic tumors occur more frequently in the liver than in any other organ. Guided percutaneous fine-needle aspiration (FNA) of the liver is often recommended for confirmative diagnosis of the metastatic lesion, because of its simplicity, high yield, and reasonable safety. The authors studied retrospectively cytologic findings of 110 cases of metastatic tumors to the liver. The frequent primary sites were the stomach (23 cases), pancreas(19 cases), gallbladder(12 cases), and periampullary lesions(6 cases). Most of the metastases were carcinoma (106 cases). There were only 4 cases of sarcoma. The characteristic cytologic findings of FNA of meatastatic tumors were dirty background, abrupt change between hepatocytes and malignant cells, and desmoplasia. Some tumors displayed rather distinctive cytologic appearance that suggests primary sites. For example, the colonic adenocarcinoma showed tall columnar cells with a palisading arrangement, adenocarcinoma of gallbaldder showed focal squamous differentiation in some cases, and metastatic renal cell carcinoma and neuroblastoma showed also distinctive cytologic findings. Because the cytologic features of metastatic tumor are very similar to those of primary tumor, correct cytologic typing may be helpful in pursuit of an occult primary site of metastatic liver lesions, reducing extensive diagnostic investigation in poor prognostic patients.

This paper is mainly on the medical comments in ${\ulcorner}$Sanbeon-bang(刪繁方)${\lrcorner}$. Among the medical comments in ${\ulcorner}Sanbeon-bang{\lrcorner}$, the Ojang-noron(五臟勞論) which deals with the Hanyeolheosil(寒熱虛實) of Ojang(五臟) and Yukgeuknon(六極論) which deals with the Hanyeolheosil of 'Geun-Maek-Yuk-Gi-Gol-Jeong(筋脈肉氣骨精)', remain perfectly. By way of these theories, it argues on various types of pathogenic states and syndromes. Related to the Ojang-noron, ${\ulcorner}Sanbeon-bang{\lrcorner}$ suggests a characteristic tonifying method which is 'Exhaustion syndromes should tonify the son organ(勞則補子法)'. It is the supplement of traditional 'Reinforcing the mother organ when treating cases of deficiency(虛則補其母)'. With the Ojang-noron, the comments about 'Samcho(三焦)' remain relatively intact in ${\ulcorner}Sanbeon-bang{\lrcorner}$. The contents are based on ${\ulcorner}$Yeongchu Yeongwisaenghoe(靈樞 營衛生會)${\lrcorner}$, combined the contents of ${\ulcorner}$Nangyeong 31st difficulty(難經 三十一難)${\lrcorner}$ and the meridian line in ${\ulcorner}$Yeongchu Gyeongmaek(靈樞 經脈)${\lrcorner}$. They were quoted untouched in ${\lrcorner}Cheongeumyo-bang{\lrcorner}$ by Son Sa-mak, and became the fundamental structure of Samcho-theory of after ages. Among the medical comments in ${\ulcorner}Sanbeon-bang{\lrcorner}$, there has been much dispute over the problem about 'Chu-Tae-eum(秋太陰), Dong-So-eum(冬少陰)'. This study will pay attention to the connection between Wang Bing's views of ${\ulcorner}Sanbeon-bang{\lrcorner}$ for compilation of ${\ulcorner}Chaju-Hwangje-Naegyeong-Somun{\lrcorner}$ and the original ${\ulcorner}Sanbeon-bang{\lrcorner}$. Judging from this study, Wang Bing may have referred to ${\ulcorner}Sanbeon-bang{\lrcorner}$, ${\ulcorner}Oedaebiyo-bang{\lrcorner}$ or another medical book of similar stock, and from this he may have reconstructed the attribute of Eum-Yang(陰陽) which is related to Pye and Sin. Wang Bing's disciples may have referred to ${\ulcorner}Sanbeon-bang{\lrcorner}$, or with Wang Do, the writer of ${\ulcorner}Oedaebiyo-bang{\lrcorner}$, building up the main medical current in those days.

Background: Prolonged usage of extracorporeal membrane oxygenation (ECMO) may induce multi-organ failure. This study is aimed to evaluate prognostic factors in the patients with ECMO. Also, the prognosis of ECMO with Kidney Injury Network Scoring system is studied. Materials and Methods: From May 2005 to July 2011, 172 cases of ECMO were performed. The cases of perioperative use of ECMO were excluded. Renal failure patient and younger than 15 years old one were also excluded. As a result, 26 cases were enrolled in this study. Male patients were 15 (57.7%), and mean age was $56.57{\pm}17.03$ years old. Demographic data, ECMO parameters, weaning from ECMO, and application of continuous renal replacement therapy are collected and Acute Kidney Injury Network (AKIN) scores were evaluated just before ECMO and day 1, day 2 during application of ECMO. Results: Venoarterial ECMO was applied in 22 cases (84.6%). The reasons for applications of ECMO were cardiac origin in 21 (80.8%), acute respiratory distress syndrome in 4, and septic shock in 1 case. Successful weaning from ECMO was achieved in 15 cases (57.7%), and survival discharge rate was 9 cases (34.6%). Mean duration of application of ECMO was $111.39{\pm}54.06$ hours. In univariate analysis, myocarditis was independent risk factors on weaning failure. Using the receiver operating characteristic curve, level of hemoglobin on 24 hours after ECMO, and base excess on 48 hours after ECMO were showed more than 0.7. AKIN score was not matched the prognosis of the patients with ECMO. Conclusion: In our study, the prognosis of the patients with myocarditis was poor. Hemoglobin level at first 24 hours, and degree of acidosis at 48 hours were useful methods in relating with prognosis of ECMO. AKIN scoring system was not related with the prognosis of the patients. Further study for prognosis and organ injury during application ECMO may be needed.

This is the study about the New Formation Developement, the Changeable Table Design with Units that made of Wasted Wood to use restricted material rationally and to improve the space efficiency in the Table Design. We made some changeable table design with units that made of laminated wood wasted. And we found out the following formative characteristic and physical merits through this study. First, the space efficiency can be improve technically through the unit combination and organic transfomation of the specific form and a new method by laminated wood make the personal originality and the structral stability be built up. Second, there are some merits, moveable convenience and variable layout by the combination or transformation or personal fondness so that economical efficiency and variable of design can be improved. Third, we can remove original faults inside wood like a knot or not-uniform of wood organ when we laminate wood so that we use proper units that have original beauty of wood and can represent mild mood of furniture wholly. Fourth, much more strengthen tensile strength by the reciprocal action among the units that be made of laminated wood reduces wood's metamorphosis like bending or twisting so that the uniformity of wood can be gain and furniture's metamorphosis can be reduced. According to changes of nature environment, the difficulty of supply and demand for wood may be happen. According to changes of life style these days, supply and demand for environment friendly material, processing technique and developement of design to improve the efficiency of using space must be very important factor in morden furniture design. So we propose changeable furniture design by using new environment friendly meterial and processing method from this study.

We determined the effect of caponization on the carcass and giblet characteristics, and skin and muscle color in Taiwan country chicken cockerels. Caponized birds were surgically altered at 10 weeks old and were fed growing and finishing diets ad libitum during an eighteen-week experimental period. The results showed that the percentage of dressing, heart, feet, thigh, head and neck were significantly (p<0.05) higher in the intact birds, while the capons had a higher (p<0.05) percentage of abdominal fat, intestine, back, wing and breast. Eviscerated weight, breast width, gizzard, liver and spleen ratios were not affected by the treatments. The breast skin color values for lightness (L*) and yellowness (b*) values in the capons were significantly (p<0.05) higher than in the intact birds, but the thigh and back skin were not significantly（p>0.05）different. Compared with the intact birds, the capons had a significantly (p<0.05) less redness (a*) values in the back skin, but were not significantly (p>0.05) different in the breast and thigh skin. The L* value of the thigh muscle was significantly (p<0.05) greater in the capons than in the intact birds, but were not significantly (p>0.05) different in breast and back muscles. The b* values in the breast, back and thigh muscles of the capons were significantly (p<0.05) greater whereas the intact birds had a higher (p<0.05) a* values in the breast, back, and thigh muscles. Moreover, our findings also indicate that the castration resulted in a significant alteration in dressing percentage, carcass region and organ percentage.

Morphological characteristics of Mesocestoides lineatus tetrathyridia collected from Chinese snakes and their adults recovered from experimental animals were studied. The tetrathyridia were detected mainly in the mesentery of 2 snake species, Agkistrodon saxatilis (25%) and Elaphe schrenckii (20%). They were 1.73 by 1.02 mm in average size and had an invaginated scolex with 4 suckers. Adult tapeworms were recovered from 2 hamsters and 1 dog, which were orally infected with 5-10 larvae each. Adults from hamsters were about 32 cm long and those from a dog were about 58 cm long. The scolex was 0.56 mm in average width with 4 suckers of 0.17 by 0.15 mm in average size. Mature proglottids measured 0.29 by 0.91 mm (av.). Ovaries and vitellaria bilobed and located in the posterior portion of proglottids. The cirrus sac was oval-shaped and located median. Testes were follicular, distributed in both lateral fields of proglottids, and 41-52 in number per proglottid. Gravid proglottids were 1.84 by 1.39 mm (av.) with a characteristic paruterine organ. Eggs were 35 by $27{\mu}m$ in average size with a hexacanth embryo. These morphological characteristics of adult worms were identical with those of M. lineatus reported previously. Therefore, it has been confirmed that the tetrathyridia detected in 2 species of Chinese snakes are the metacestodes of M. lineatus, and 2 snake species, A. saxatilis and E. schrenckii, play the role of intermediate hosts.

Amyloidosis comprises a diverse group of systemic and local diseases characterized by organ involvement by the extracellular deposition of fibrils composed of subunits of a variety of normal serum proteins. Secondary amyloidosis is caused by the deposition of amyloid A(AA) protein in chronic inflammatory disease. Juvenile rheumatoid arthritis(JRA) has been known to be the most common cause of secondary amyloidosis. We experienced one case of secondary renal amyloidosis in a 12-year-old girl who had suffered from JRA for several years who had visited our renal clinic to evaluate the proteinuria with microscopic hematuria which was detected by chance at school urine screening examination. Apple green birefringence was observed under polarized light with Congo red stain at)d characteristic electron microscopic findings was also noted in renal tissues which was obtained by percutaneous renal biopsy. In our knowledge, this is the first case report of secondary renal amyloidosis developed in pediatric age in Korea.

A new sudden death in rabbits appeared in China and Korea in 1984 and 1985, respectively, and was recognized to be an acute infectious disease caused by a virus. The disease was reported as a "new viral disease," and thereafter, a tentative name of "viral hemorrhagic disease", "hemorrhagic pneumonia" or "viral hemorrhagic pneumonia" has been described in the case reports. But authors had called the viral disease "rabbit viral hepatitis" due to picornavirus infection, because the principal lesion of the disease was an acute hepatitis. The purpose of this report is to describe the electron microscopic findings on the livers in experimentally infected rabbits. All the livers of the affected rabbits were shown to have degenerative changes of a type that is characteristic of acute hepatitis. In the liver cells, there were dilation of rER and mitochondria, vacuole formation of various sizes, and appearances of many virus-like particles in the vicinity of rER, granular bodies and crystalline arrays of viral particles in the cytoplasm with necrotic changes of the nucleus. Clusters of virus-like particles and viral crystals appeared in the cytoplasm of sinusoid endothelial cells and Kupffer's cells with morphological changes of organelles. Also viral crystals were demonstrated in the cytoplasm of macrophages among the liver cells. On the whole, the liver cells had many virus-like particles and a few crystalline arrays of viral particles. Therefore, this implies that the liver cells are the main site of the viral replication in inducing the viremia. It was concluded that the liver was the primary target organ of this viral disease, and the pathological and the ultrastructural evidence suggest that the virus may be belong to genus enterovirus.

Churg-Strauss syndrome (CSS) is a disorder that is characterized by asthma, hypereosinophilia and systemic vasculitis affecting a number of organs. The manifestations of acute cholecystitis and diffuse alveolar hemorrhage are rarely reported in CSS. A 22-year-old woman with bronchial asthma visited our hospital complaining of right upper quadrant pain with a sudden onset. The abdominal computed tomography (CT) scan revealed gall bladder edema consistent with acute cholecystitis. On the initial evaluation, marked hypereosinophilia was observed in the peripheral blood smear. The nerve conduction velocity measurements and a skin biopsy performed to confirm the organ involvement of disease indicated typical mononeuritis multiplex and necrotizing vasculitis, respectively, which was complicated with CSS. On the 12th hospital day, ground glass opacity and consolidations were newly developed on both lung fields. The bronchoalveolar lavage (BAL) fluid showed increasing bloody return in sequential aliquots that were characteristic of a diffuse alveolar hemorrhage. We report a case of CSS with acute cholecystitis and diffuse alveolar hemorrhage.
