As an ode well-known throughout the history, ode to lotus is very familiar to everyone, old and young, man and woman. However, such issues as to what degree the people of each generation in the past and at present accepted it, what characterizes their acceptance of it, and whether Zhou Dunyi is the author, have been neglected. This thesis makes an attempt to have a brief exploration and sorting of these issues, which seem minimal and are therefore ignored, and it also has some textual criticism and analysis on it based on the related materials.

This paper aims to research in So Pyo written by Lee Kyu-bo about the Mongolian a99ression into Koryo. Through Soˇ Pyo, his best work, he showed his affection for the people, for the society, and for the nation. Although a lot of works were written by him, Soˇ Pyo was the best one in which his thought and his intention on the real society at that time leas described very well. I believe that he was bright on the history, so he showed a strong history consciousness in the relationship of literature and history through his senses of literature. The outline of this paper is as follows. 1. introduction 2. summary of Korean history and its geographical environment 3. research on the historical background at that time when he lived 4. research on the literary background at that time when he wrote literary works 5. showing real examples of his historical consciousness appeared in Soˇ Pyo, which was a book about the Mongolian invasion into Koryo, and which was written on the basis of strong historical consciousness 6. investigation of what the author's thought to write Soˇ Pyo was and what his historical intention to write it was 7. conclusion I maintain that Lee Kyu-bo was so patriotic to his country and so affectionate for the people that he deserve to be praised as one of the best historians and lest literary men in the Koryo dynasty. Especially he made a great effort to inspire the morale of the people depressed by the Mongolian raid.
Somatic mutation patterns and compound response in cancers
( Ning Ning He ),( Na Young Kim ),( Suk Joon Yoon ) 생화학분자생물학회(구 한국생화학분자생물학회) 2013 BMB Reports Vol.46 No.2
The use of various cancer cell lines can recapitulate known tumor-associated mutations and genetically define cancer subsets. This approach also enables comparative surveys of associations between cancer mutations and drug responses. Here, we analyzed the effects of ∼40,000 compounds on cancer cell lines that showed diverse mutation-dependent sensitivity profiles. Over 1,000 compounds exhibited unique sensitivity on cell lines with specific mutational genotypes, and these compounds were clustered into six different classes of mutation-oriented sensitivity. The present analysis provides new insights into the relationship between somatic mutations and selectivity response of chemicals, and these results should have applications related to predicting and optimizing therapeutic windows for anti-cancer agents.

A new androstane derivative, 4β-methyl-15-oxa-14β-androstane-7-ene-4α-carboxylic acid (1) and a known one 4β-methyl-15-oxa-14β-androstane-7-ene-4α-hydroxyl (2) were isolated from the EtOAc extract of the cultures of the fungus Marasmiellus ramealis (Bull.) Singer. Their structures were elucidated on the basis of 1D and 2D NMR as well as MS spectroscopic data analysis. The inhibitory activity of two isolates against acetylcholinesterase (AChE) revealed that compound 1 exhibited definitely inhibitory activity.
Carbon-Ion-Implanted Nd, MgO-Codoped Near-Stoichiometric Lithium-Niobate Optical Waveguides

Nd, MgO codoped near stoichiometric lithium niobate (Nd:MgO:SLN) is a promising laser gain crystal for infrared laser generations. We report on, to our knowledge for the first time, the planar waveguide formation in Nd:MgO:SLN crystal by MeV carbon ion implantation at dose of 1014 ions/cm2. The guiding properties are investigated by using the well-known m-line technique and end-face arrangement. The refractive index profiles of the waveguides show a typical “well + barrier” distribution, which could confine the light propagation in a non-leaky way. In addition, a numerical simulation of the light propagation shows that the waveguide modal distributions are in good agreement with the experimental data, which means potential applications for the formation of designable devices in Nd:MgO:SLN by using carbon ion implantation.

Objective: Although endoscopic drill has the advantages in manipulation and hemostasis, whose low efficiency and blurred vision reduce the efficacy of lumbar endoscopic unilateral laminotomy with bilateral decompression (LE-ULBD). The present study was designed to evaluate the safety and efficacy of full-visualized trephine/osteotome in the LE-ULBD surgery for severe lumbar stenosis. Methods: Fifty-seven severe lumbar stenosis patients who underwent LE-ULBD between January 2020 to January 2023 were enrolled, who were divided into drill and visualized trephine groups. The medical records including demographics, operative duration, intraoperative electrophysiological findings, postoperative hospital stay or hospital stay, postoperative outcomes and complications were retrospectively reviewed and analyzed. Results: A total of 57 patients included 15 in drill and 42 in trephine group were enrolled in the study. There was significant difference in the pre- and postoperative visual analogue scale and Oswestry Disability Index scores in both groups (p < 0.05). The mean operative duration in the trephine group (101.05 ± 12.18 minutes) was shorter than that in the drill group (134.67 ± 9.68 minutes) (p < 0.05). There was no statistical difference between the 2 groups in electrophysiological monitoring, posthospital stays, postoperative outcomes and complications. Abnormal free-electromyography (EMG) were recorded in 2 (13.3%) and 5 patients (11.9%) in the drill and trephine group. Intraoperative somatosensory evoked potential changes occurred in 3 (20%) and 3 patients (7.1%) in the drill and trephine group and all patients recovered immediately when surgery ended. No serious complications and recurrence occurred in all the patients. Conclusion: Full-visualized trephine/osteotome has been approved to be convenient, safe and efficient in our study, which combined with translaminar inside-out technique and EMG monitoring especially free-EMG may offer a new choice in LE-ULBD surgery for lumbar stenosis patients.

Ning-ning Wang,Yun-xiang Lan,Jie He,Rui Dong,Jin-song Hu 대한화학회 2013 Bulletin of the Korean Chemical Society Vol.34 No.9
The layered KTiNbO5 was successfully synthesized with titanium(IV) isopropoxide and niobium oxalate by a novel polymerized complex (PC) method. The morphology and structure of the as-prepared sample was characterized by means of High-Resolution Transmission Electron Microscope, powder X-ray diffraction, and Laser Raman Spectroscopy. The spectral response characteristic was recorded by using UV-vis Diffuse Reflectance Spectroscopy. Results show that KTiNbO5 as-prepared by PC method presents an uniform morphology of nano-particles, the mean particle sizes is ca. 28 nm corresponding to the (002), and the crystal structure can be well indexed to the orthorhombic phase. The sample as-prepared by PC method has higher band gap energy than that of the sample prepared by a solid-state reaction method due to the quantum size effect.

The purpose of the present study was to investigate the effects of resveratrol supplementation on oxidative damage and lipid peroxidation induced by strenuous exercise in rats. The rats were randomly divided into five groups: a sedentary control group, an exercise control group, and three treatment exercise groups administered increasing doses of resveratrol (25, 50, and 100 mg/kg body weight). Resveratrol was administered by oral gavage once daily for four weeks. At the end of the four-week period, the rats performed a strenuous exercise on the treadmill, and the levels of lactate dehydrogenase (LDH), creatine kinase (CK), malondialdehyde (MDA), 4-hydroxy-2-nonenal (4-HNE), and 8-hydroxy-2``-deoxyguanosine (8-OHdG) were measured. The results showed that resveratrol supplementation had protective effects against strenuous exercise-induced oxidative damage and lipid peroxidation by lowering the levels of LDH, CK, MDA, 4-HNE, and 8-OHdG in the serum or muscle of rats. These beneficial effects are probably owing to the inherent antioxidant activities of resveratrol.
