  • The study examines the U.S. Small Business Innovation Research (SBIR) program, with a focus on the recent Reauthorization, and compares, in the political context, the U.S. and East Asian countries-Japan, Korea and Taiwan-that adopted the U.S. SBIR program. For the systematic analysis and cross-country comparison, the study employs Kingdon (2003)'s framework-his political theory and Garbage Can Model-to identify political participants and processes underlying the SBIR Reauthorization and to analyze the differences in problem, policy, and politics streams between the U.S. and East Asian countries. For the cross-country comparison, specifically, the study uses various data sources such as OECD, Global Entrepreneurship Monitor, Hofstede's Cultural Dimensions, and World Value Survey. Based on the analysis outcomes, implications of U.S. practices on East Asian countries are extracted as follows. East Asian countries tend to: Have higher entrepreneurial aspiration while lower entrepreneurial activity and attitude than the U.S.; bear higher long term orientation and uncertainty avoidance while lower individualism than the U.S.; and have greater expectations of technology development and higher confidence in political parties while participating less in political action than the U.S. Drawing on the differences, the following policy recommendations are suggested. East Asian countries should: Improve entrepreneurs' access to resources (in particular, financial resource) in order to link their high entrepreneurial aspiration to actual entrepreneurial activities; cultivate failure-tolerating culture and risk-taking entrepreneurs, for instance, by providing a second chance to SBIR-participating businesses that failed to materialize their innovative ideas; and leverage their high expectations of new technology in order to take bold actions regarding their SBIR programs, and update the programs by drawing out constructive dialogues between SBIR stakeholders.

  • The purpose of this is to analyze the aesthetics characteristics of our modern sports fashion, and thereby, discuss them in the light of the overall mentality or the 20th century, and thus, present the conditions or sports fashion design meeting modem people's divers aesthetics values and desired. Modern sports fashion sues can be categorized into futurist sports style, erotic sports style and American sheet sports style. And the 20th century mentality characterized by changes of lifestyle, identity and aspiration has influenced the aesthetic features of such sports fashion sues, which can be summed up as follows; first, the futurist sports style applies the functional items and details of active sportswear to design, while heralding a positive and hopeful message of technology and future by using the material of hi-tech functions and senses. This sports style was affected much by shift from social status, attraction and wealth to demonstration of state-of-the-art science, pursuit of functionality in terms of shapes and materials, convenience through See combinations of sportswear items or design elements. Second, the erotic sports style based on minimalism attempted to express the erotic body beauty indirectly by exposing some parts of body or using the material pressed against the body. This sports style was closely related with the changes of sexual identity such as neutral sexualism, bi-sexualism and homo-sexualism. Lastly, the American street sports style was born from black Americarns' sports and dances. This spors style pursues “youth” beyond TPO concept As mass media and commercial sports developed, the young generation copied sports stars' uniforms or fashions to share honor, wealth and youth with them. In sort, the American sheet sports style was affected much by the so-called “heroism”. Such a changed object of aspiration influenced the aesthetic characteristics of American shot sports style directly.

  • This is a thesis about the experiment of comparison characteristic of power and exhaust gas in the same condition between diesel engine that is equipped response power 220HP turbocharger to increase effectiveness of the engine which is recently used in a lot of industry which requires high power. Resulting of the experiment with natural aspiration diesel engine and turbocharger diesel engine, difference in low speed is not significant, but in high speed, effectiveness of turbocharger diesel engine is much higher than the other one. In other hand, in exhaust gas experiment, turbocharger model exhausts more $NO_X$ and $O_2$, but it doesn't significantly affect the result when it comes with decreasing of $CO_2$ and effectiveness of increased power characteristic. As a result, the turbocharger diesel engine is economically effective comparing with the natural aspiration diesel engine.

  • Recently as the ultrasonography became generalized, the annual change rate of the incidence of thyroid cancer extraordinarily grew to 24.5% in Korea. Therefore, the aim of this study was performed to identify the risk factors of thyroid cancer apart from conventional risk factors of dietary iodine and ionizing radiation. In this retrospective study, 411 patients underwent fine-needle aspiration biopsy were examined from January 2011 to March 2013. The subjects are divided into two groups which are 260 patients with benign nodule and 151 patients with malignancy nodule. We compared age, hematologic values, body mass index, waist circumference, menopausal status, breast nodules status, uterine myoma status, fatty liver status of targeted group of patients. According to the result, in thyroid cancer group with obesity, the number of case of breast nodules and myoma was higher, and their thyroid stimulating hormone values was higher than the benign nodule group. In order to establish factors influencing thyroid and thyroid cancer, there is a definite need for continuous study.

  • An 11-year-old male Rex rabbit (Oryctolagus cuniculus) had a rectal prolapse induced by a polypoid mass. The mass was highly vascularized with a cauliflower-like appearance. Anorectal papilloma was suspected, and fine needle aspiration cytology showed eosinophilic inflammation. After surgical removal of the polyp, postoperative care was given, such as systemic antibiotics and analgesics. In the re-examination, the rabbit was resolved, and there were no complications. Histopathological examination of the removed polyp indicated chronic eosinophilic proctitis to be the cause of the inflammatory condition of the protruding rectal polyp.

  • A 7-year-old castrated male Yorkshire Terrier presented for a palpable mass of the right neck with ophthalmic signs of conjunctival hyperemia and anisocoria with fixed mydriatic pupil of the right eye. Clinical examination findings included the absence of direct and consensual pupillary light reflexes, external and internal ophthalmoplegia, and corneal hypoesthesia with incomplete blinking of the right eye. Magnetic resonance imaging and computed tomography revealed a mass extending from the right cavernous sinus to the orbital fissure with neighboring bone lysis. Cytological examination of fine-needle aspiration samples of the mass revealed a neuroendocrine tumor. The owner declined further diagnosis and did not wish to care for the dog receiving chemotherapy. This study describes the importance of investigating neuro-ophthalmic findings, which might provide clues for the localization of lesions, including tumors, to aid in diagnosis.

  • Purpose The objective of this study was to evaluate the diagnostic value and threshold levels of cytokeratin fragment 21-1 (CYFRA 21-1) in fine-needle aspiration (FNA) washouts for detection of lymph node (LN) recurrence in postoperative breast cancer patients. Materials and Methods FNA cytological assessments and CYFRA 21-1 measurement in FNA washouts were performed for 64 axillary LNs suspicious for recurrence in 64 post-operative breast cancer patients. Final diagnosis was made on the basis of FNA cytology and follow-up data over at least 2 years. The concentration of CYFRA 21-1 was compared between recurrent LNs and benign LNs. Diagnostic performance and cut-off value were evaluated using a receiver operating characteristic curve. Results Regardless of the non-diagnostic results, the median concentration of CYFRA 21-1 in recurrent LNs was significantly higher than that in benign LNs (p < 0.001). The optimal diagnostic cut-off value was 1.6 ng/mL. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CYFRA 21-1 for LN recurrence were 90.9%, 100%, 100%, 98.1%, and 98.4%, respectively. Conclusion Measurement of CYFRA 21-1 concentration from ultrasound-guided FNA biopsy aspirates showed excellent diagnostic performance with a cut-off value of 1.6 ng/mL. These results indicate that measurement of CYFRA 21-1 concentration in FNA washouts is useful for the diagnosis of axillary LN recurrence in post-operative breast cancer patients.

  • The occurrence of a mixed tumor containing papillary thyroid carcinoma (PTC) and primary squamous-cell carcinoma (SCC) is rare because there is no squamous epithelium in the thyroid gland. Reported herein is a 30-year-old female with mixed PTC and primary sec of the thyroid presented as thyroid incidentaloma. Fine-needle aspiration biopsy of the thyroid nodule revealed the presence of malignant thyroid cells. The histopathological examination following total thyroidectomy yielded two mixed, morphologically distinct histotypes that included PTC and sec. After total thyroidectomy, the patient underwent radioactive iodine therapy. No recurrence or metastasis occurred during the 20-month follow-up period after the operation.

  • The prodrug and antedrug concepts, which were developed to overcome the physical and pharmacological shortcomings of various therapeutic classes of agents, employ diametrically different metabolic transformations. The prodrug undergoes a predictable metabolic activation prior to exhibiting its pharmacological effects in a target tissue while the antedrug undergoes metabolic deactivation in the systemic circulation upon leaving a target tissue. An increased therapeutic index is the aspiration for both approaches in designing as well as evaluation criteria. The recent research endeavors of prodrugs include the gene-directed and antibody-directed enzymatic activation of a molecule in a targeted tissue, organ specific delivery, improved bioavailabilities and cellular penetration of nucleotides. As for antedrugs, emphasis in research has been based upon the design and synthesis of systemically inactive molecule by incorporating a metabolically labile functional group into an active molecule.

  • In this study, we investigated factors for affecting pneumothorax in percutaneous needle aspiration biopsy of lung lesions. This research were conducted at University Hospital in Daejeon from August 2007 to May 2008. Total 104 patients between the ages of 25~85 who had focal lung lesions were grouped in terms of the tumor location, tumor size, depth of lesion, gender, age, biopsy time, and the number of biopsies. Then, their correlations with pneumothorax were studied. The incidence of pneumothorax according to the positions showed 27.3% in the right lower lobe, 24.3% in the right upper lobe, 15% in the left lower lobe and 12% in the left upper, respectively. In addition, the incidence by lesion size showed 24.0% in 0~2.0 cm, 18.2% in 2.1~4.0 cm, above 20.0% in 4.1 cm respectively. The probabilities of pneumothorax was 6.7% at 0 cm depth of lesion, 24.2% at 0.1~2.0 cm and greater than 26.8% at 2.1 cm. By gender differences, we found that probability of incidence of pneumothrax is 21.7% for male and 17.1% for female. According to age, pneumothorax occurred in 25% in the group of less than 40-years-old, 11.7% in 41~50 years, 14.3% in 51~60 years, 24.1% in 61~70 years old and 24.1% in over 70 years. According to the time of biopsy, the incidence of pneumothorax was 3.8% from 0 to 10.0 minutes, 18.9% from 10.1 to 20.0 minutes and 40% more than 21 minutes.
