The main purpose of the thesis is to pursue the Dadaistic features of Lee-sang`s Poetry. Lee-sang`s Poetry, as a whole, is discoursed in the Dadaism and the Surrealism. Both of these are not technical but social and historic. Especially, among these two terms Dadaism, first of all, regards to the social and history, they have negative sprit. In this respcet, I studied Lee-sang`s Poetry. As the result of this point of view, he was a poet who wrote poem fiercely as like the fighter, in the colonical era. His negative thought should be realive through the modern poets. In order that his dadaistic spirit accepted the aethetic dialectic, he said, desperate give birth to technic(language) and technic(language) give birth to desperate. That`s the reason why we think over and over.

Purpose: The prognosis of papillary thyroid carcinoma is determined by such risk factors as old age, male gender, a large tumor size and extrathyroid extension. The aim of this study was to investigate the value of extrathyroid extension for the recurrence of papillary microcarcinoma and its association with the risk factors for papillary thyroid carcinoma. Methods: We retrospectively studied 167 patients with papillary microcarcinoma and who underwent thyroidectomy from Feb. 2003 to Dec. 2008. Papillary microcarcinoma (PTMC) was defined as a tumor smaller than 1 cm and an extrathyroid extension was identified by the pathological findings. Age, gender, extrathyroid extensions, the operative methods, lymph node metastasis and the MACIS score were analyzed by the appropriate statistical methods. Results: Patients with PTMC showed a lower MACIS score, fewer lymph node metastasis and less extrathyroid extension, as compared to the patients with papillary thyroid carcinoma. Total thyroidectomy and selective lymph node dissection were less frequently done in the patients suffering with PTMC. Analysis of the risk factors showed that PTMC had a close relationship with lymph node metastasis, the extent of surgery and multifocal cancer. The disease free survival rate of the patients with PTMC was statistically related with lymph node metastasis, but not with an extrathyroid extension (P=0.001). Conclusion: The patients with PTMC showed less lymph node metastasis and extrathyroid extension as compared to the patients with PTC. Lymph node metastasis of PTMC is an independent factor for disease free survival, but minimal extrathyroid extension is not related with recurrence. PTMC with lymph node metastasis should be regarded as an aggressive large tumor and lymph node dissection should be done. (Korean J Endocrine Surg 2008;8:243-249)

ZnO-$Fe_2O_3$ 복합금속 산화물 흡착제가 황화수소 제거능이나 황화된 흡착제의 산화적 재생반응에 미치는 영향을 고찰하였다. Zinc ferrite 흡착제가 가장 높은 황화수소 제거능을 나타내었고 혼합한 $Fe_2O_3$ 흡착제는 황화반응 도중 H$_2$S의 생성을 촉진시킴을 알 수 있었다. 또한 황화반응의 결과로 생성되는 금속황화물들이 H$_2$S 열분해의 촉매로 작용하였으며 H$_2$는 $Fe_2O_3$의 함량이 증가할수록 더 많이 발생하였다. 산화적 재생반응의 결과로부터 ZnS를 제외하고 $Fe_2O_3$를 혼합한 흡착제는 모두 잘 재생됨을 알 수 있었다. 또한 산화적 재생반응 도중 생성될 수 있다고 보고된 zinc sulfate는 생성되지 않았다. 그리고 SO$_2$ 발생 곡선의 형태나 완전재생에 소요되는 시간을 기준으로 판단해 볼 때 $Fe_2O_3$의 혼합량의 변화는 산화적 재생반응에 별다른 영향을 미치지 않음을 알 수 있었다. Introduction : Recently, water and environmental pollution becomes serious social problem and high technology makes this pollution accelerate. Hydrogen sulfide, the main subject of our research, is one of the most dangerous air pollutant like SO$_x$ and NO$_x$. The major contaminant in coal gasification is H$_2$S, which is very toxic, hazardous and extremely corrosive. Therefore, control of hydrogen sulfide to a safe level is essential. Although commercial desulfurization process called liquid scrubbing is effective for removal of H$_2$S, it has drawbacks, the loss of sensible heat of the gas and costly wastewater treatment. Many investigations are carried out about high-temperature removal ol H$_2$S in hot coal-derived gas using metal oxide or mixed metal qxide sorbents. It was reported that ZnO was very effective sorbent for H2S removal, but it has big flaw to vaporize elemental zinc above 600\ulcorner \ulcorner As alternative, metal oxides such as CaO, $Fe_2O_3$, TiO$_2$ and CuO were added to ZnO. Especially, different results are reported for $Fe_2O_3$ additive. Tamhankar et al. reported SiO$_2$ with 45 wt% $Fe_2O_3$ sorbent is favorable for removal of H$_2$S and regeneration.

Among the various types of diesel after-treatment device, the corona discharge reactor may be considered as a powerful process for trapping submicron particles. But after precipitation on the electrodes occurs, the reentrainment of particles is severe and often causes low or negative precipitation efficiency. Experiments were performed to investigate the effect of an applied voltage on the reentrainment of soot particles from the electrodes. A co-annular laminar diffusion flame burner was used as the soot generator. When a highly negative voltage was applied, exfoliation of the deposited soot particles and an increase in concentration of particles smaller than approximately 150 nm were observed. Turbulence induced from the negative tuft corona and sputtering caused particle reentrainment from the corona wire and from plates as well. Under soot laden combustion gas, a streamer corona often occurred in the wire-cylinder reactor. Because of its transient nature, streamer corona violently increased the concentration of reentrained particles and CO gas.

Electrospraying comprises the generation of liquid droplets by applying a high voltage to the surface of a liquid. By monitoring the current and the flow rate it was possible to obtain a stable cone jet mode in a given condition. In this work the liquid contained NaCl particles resolved in distilled water. The NaCl particles increased concentration of the ionized solution and thus increased electrical conductivity of the liquid, which was inversely proportional to the flow rate in the cone jet mode. A number of sprayed droplets were sampled and dried enough, and then the size of NaCl particles were measured. The measured droplet diameter was a little larger than two theoretical diameters, Rayleigh diameter and mobility diameter.

양성 갑상선 결절의 내과적 치료

Thyroid nodules are frequently diagnosed today, mainly due to the wide use of neck ultrasonography (US). The majority of these lesions are benign; suspicion for malignancy is an indication for surgery, while benign thyroid nodules may be managed conservatively. There is evidence that a large percentage of patients with thyroid nodules are over-treated. Careful and accurate identification of patients with thyroid nodules that are highly suspicious for an underlying malignancy would allow for a more reasonable therapeutic approach and would result in a reduction of the number of unnecessary thyroidectomies. Fine needle aspiration cytology is currently the most accurate and cost effective diagnostic approach for the evaluation of patients with nodular thyroid disease. Completely asymptomatic nodules require follow-up without treatment. Cosmetic problems or compression related symptoms may be indications for surgery. When surgery is contraindicated or refused, several non-surgical approaches are available. These include levothyroxine therapy, radioiodine treatment, injection of percutaneous ethanol and laser photocoagulation. Levothyroxine therapy is the most widely used approach, but its clinical efficacy and safety are controversial. Treatment with radioiodine is the therapy of choice for toxic nodules or for symptomatic nodular goiters when surgery is not possible. Percutaneous ethanol injection should be used as the first-line therapy for recurrent symptomatic cystic nodules. Laser therapy should be reserved only for selected patients treated in experienced centers. With these options, clinicians can personalize the management of nodular thyroid disease according to a careful cost benefit analysis. (Korean J Endocrine Surg 2007;7:1-8)
