Cystic Medullary Thyroid Carcinoma: A Case of Undergoing Endoscopic Thyroid Lobectomy
Dong Hae Chung,Jae Yeon Seok,Yoo Seung Chung1,Eun Mee Oh1,Jung Won Ryu1,Young Don Lee1 대한갑상선-내분비외과학회 2015 The Koreran journal of Endocrine Surgery Vol.15 No.1
On ultrasonography, medullary thyroid carcinoma (MTC) shows hypoechogenicity, an irregular margin, a predominantly solid composition, and microcalcifications, similar to those observed in papillary thyroid carcinoma (PTC). MTC presenting as a cystic lesion is rare, and endoscopic thyroidectomy can be performed for benign thyroid masses and early stage PTC, however it is inappropriate for MTC regardless of cystic change. The authors report a case of cystic MTC found after endoscopic thyroid lobectomy and provide a review of the literature on this topic.

To study the efficacy monoclonal antibody(MAb) against bovine rotavirus(BCV) in treatment of calf diarrhea, the MAb was fed to 166 calves with diarrhea from Chung-buk area. The results were summarized as follows. 1. Among the 1,049 calves investigated, 166(16%) calves were infected with BCV. 2. The monthly rate of BCV infection were higher in October to December compared with other months of the year. 3. Among the 166 calves with diarrhea, 137(83%) calves were recovered. 4. Young calves within 7-day-old were more effective in treatment than other ages and the rate of treatment was 86%. 5. Most effective period for treatment of rotavirus was at the first stage of infection.

Gui-Sun Moon, Sun-Woong Kim, Jeong-Ah Shin, Hae-Kyung Wee, Jong Un Park, Myung-Kwan Park, and Wonil Chung. 2018. Voice Mismatch Meets Neurolinguistics. Studies in Modern Grammar 99, 85-115. This paper aims to investigate Korean advanced L2 English learners’ strategies for ellipsis resolution during sentence processing. Ellipsis resolution is known to involve several stages of information processing from the initial step of detecting an ellipsis-licensing element by the parser to the final stage of integrating the ellipsis site with the information retrieved from the antecedent of the ellipsis site. In examining these steps, we have manipulated three factors: (i) TP vs. VP-ellipsis; (ii) two types of discourse coherence relations (resemblance(-contrast) vs. cause-effect relations); (iii) voice match vs. mismatch. We found through the ERP recordings that voice mismatch in TP ellipsis elicited N400, followed by P600, irrespective of discourse coherence relations. In contrast, voice mismatch in VP-ellipsis registered N400 only in resemblance(-contrast) relation, but not in cause-effect relation. These findings lead us to conclude that Korean advanced L2 learners of English seem to undergo the full sequence of processing stages required for ellipsis resolution.
Polyurethane Foam을 이용한 방향족 유기 화합물의 흡착에 관한 연구
정순량,오해범 又石大學校 1981 論文集 Vol.3 No.-
This study discribes liquid-solid extraction for the adsorption of aromatic compounds in aqueous media by using polyurethane foam (OPP foam). As a result, the following conclusion has been obtained. 1. The adsorption behaviors of the aromatic compounds on OPP foam are likedly caused to Van der Waals attraction between the organic molecule and OPP foam matrix, as well as due to hydrogen bond and dipole-dipole interaction between the functional groups of organic molecules and hydroxy or amide group of foam matrix. 2. The Kd values are influenced by the several factors such as molecular weight. pKa. polarity. pH medium, salting out effect of electrolyte and the effect related to the addition organic solvent.

Tis study has been done to review the historical development of the classification schemes with priority given to the classification of Knowledge and Libry classification before DDC. The finding can be sumarized as follows; 1. Knowledge classificaation schemes have been made by philosophers. Philosophers made and attampt to provide a philosophical system of knowledge of its own. The approach of the philosophers was to group ideas according to their degree of mutual relationship and they also arranged these groups in a helpful sequence, as preferred by each. 2. Knowledge classification schemes used the subjective approach, where grouping was often meaningless, and followed dichotomy and trichotomy. These schemes were Vedic, Greek, Scholastic, Baconian,Kant, and Hegel's Classification. 3. A number of Knowledge Classification schemes (Serial Classification)were made an attempt to provide place for the application of each discipline after the discipline which forms its basis or foundation. These schemes were Hobbs,Comte,Ampere and Speer's Classification. 4. We are assured that the Assiran Library's clay tablets were divided into two classes-Knowledge of Earth and Knowledge of Heavens-and Callimachus were arranged chronologically by perios and, in the shorter subjects, alphabeti-cally by the names of authors. 5. Gabriel Maude were divided into twelve main classes, which is generally considered to be the foundation of the French Systems. This system worked out in great detail by Brunet, who were divided into five main classes and eleven thousand sub-divisions. Brunet's schemes influenced the classification system in the British Museum Library. 6. Harris's system was the inverted Baonian schems and his system influenced the system of Melvil Deway(Deway Decimal Classification).
密閉床에서의 NAA 浸漬處理 前에 酸과 鹽基의 處理가 여러 觀賞植物의 揷木發根에 미치는 影響
鄭海駿 培林大學校 1981 論文集 Vol.2 No.-
This experiment was conducted to see the effect of pretreatment with acid or base proir to NAA treatment on rooting of various ornamental plants in vinyl moist chamber. Bougaivillea glabra, Acer palmatum var. dissectum, Ligustrum obtusifolium var. variegata were considerably promoted the number of roots by basal dipping in pH10.5 prior to applying α-naphthalene acetic acid for rooting cuttings, more than pH 7.0 prior to the NAA. Chanomeles sinensis showed increase in the root number with pretreatment of 2N-H₂SO₄ prior to NAA treatment slightly more than NAA 200ppm treatment, and the NAA at pH7.0 without acid treatment promoted the rooting of Viburnum awabuki, Vinca minor and Osmanthus ilicifolius likewise. Rhododendron yedoens showed a promoted rooting by pH12 NaOH+NAA a bit more than NAA at pH7.0 and Rhododendron mucronulatum showed usefulness of rooting with acid or base before NAA treatment in vinyl moist chamber.

Action potential of a frog ventricular cell was studied by conventional 3M KCI glass microelectrodes to investigate the effect of freeze-dried Korean snake venom. Following results were obtained; 1. Time to repolarize 50% of its action potential increased from 756±26mS to 796±17mS. 2. The notch which would be seen after the fast depolarization disappeared and the overshoot potential significantly decreased from 24.4±0.9㎷ to 17.8±2.3㎷. 3. Positive depolarization rate (dV/dt max) decreased from 22.8±0.8V/s to 18.8±0.8V/s. 4. Resting membrane potential was -95±3.0㎷ and showed little change. Above results would be interpreted that the Korean snake venom blocked the fast sodium channel and slow calcium channel simultaneously to reduce the contractility and activation of potassium channel which could result the prolongation of action potential duration.

Thin amorphous carbon film were deposited by Q Nd:YAG 532nm laser ablation from 99.7% graphite target with beam power density of 6x10 15 Wcm-2. In order to estimate the quality of the PLD(Pulsed Laser Deposition) film one of the most important optical properties, bandgap energy, was characterized by visible transmission and an optical bandgap energy of 2.05eV was achieved. Comparing our result with the published values in the literature we have confidence that our film shows the good quality at optical properties.
