Economic crisis, efforts to overcome the digital contents industry development at home and abroad have been racing in the country's future lies in the digital contents industry. Therefore, the digital contents industry through vision, model identification knowledge-based global digital contents market-based deployment is required. For research purposes the digital contents industry to derive an alternative to national industrial development that will lay the groundwork. The deployment order for the first digital contents industry, SWOT analysis performed to derive the Korean-specific model. As a result, measures based on the advancement of digital content industry as a long-term vision and specific goals are presented as staged. The age of convergence of the u-media content markets in government, corporations, consumers, and these form the structure of a virtuous cycle distribution systems for energy by being active, synergistic effects are obtained. First of all internal and external content, industry-based to ensure that growth is key. Vision of the digital contents, the growth momentum of the national social development policies as a role model by changing the sequence of events need to go. Key Words :Digital Contents, Creative Industry, Digital Contents Policy, Vision Model

Background: Coughing is a side effect of opioids that is rarely studied. Here, we evaluated the incidence of remifentanil induced coughing during anesthesia induction in an attempt to identify its risk factors and to examine the preventive effects of lidocaine and salbutamol. Methods: A total of 237 patients scheduled to undergo general anesthesia were allocated randomly into three groups. Group C received no medication, while Group L received 2% lidocaine at 0.5 mg/kg intravenously 1 minute prior to remifentanil infusion and Group S inhaled one metered aerosol puff of salbutamol 15 minutes prior to entering the operating room. Remifentanil was infused at 5 ng/ml by target controlled infusion and coughing was measured for five minutes and graded as none, mild, moderate, or severe based on the number of coughs. Results: The incidences of coughing were 30.4%, 25.3%, and 35.4% in Groups C, L, and S, respectively. The incidences, onset times, and severity of coughing did not differ significantly among groups. In addition, multivariate analysis showed that non-smoking and a lower body weight were risk factors of remifentanil-induced coughing (odds ratio, 8.13; P = 0.024, 1.11, and 0.004, respectively). Conclusions: The incidence of remifentanil-induced coughing was 30%. A total of 0.5 mg/kg lidocaine and 1 metered aerosol puff of salbutamol did not prevent coughing. Non-smoking and low body weight were found to be risk factors of remifentanil-induced coughing. (Korean J Anesthesiol 2010; 59: 319-322)

Sympathetic Block for Treating Primary Erythromelalgia
Bang, Yoo-Jin,Yeo, Jin-Seok,Kim, Si-Oh,Park, Young-Hoon The Korean Pain Society 2010 The Korean Journal of Pain Vol.23 No.1
Primary erythromelalgia is a rare condition that’s characterized by erythema, an increased skin temperature and burning pain in the extremities. The pain is often very severe, and treating erythromelalgia is frustrating and difficult. We report here on the case of a 12-year old girl with primary erythromelalgia in both lower extremities. The pain was refractory to medical treatment, but a bilateral sympathetic block with lidocaine and triamcinolone resulted in relief from the pain. Our experience with this disease demonstrates that sympathetic blocks are effective in improving the symptoms and they may be attempted on erythromelalgia patients who do not respond to other treatments, including medication and epidural blocks.
Effects of Chitooligosaccharide Lactate Salt on Activity of Acetaldehyde Dehydrogenase

Chitooligosaccharides (COS), a kind of oligosaccharide made from chitin or chitosan, have been used a popular remedy for hangovers. In this study we investigated the in vitro effect of COS lactate salt on ethanol-induced cytotoxicity and the in vivo effect of short-term COS lactate salt feeding on ethanol-induced hangover. Pretreatment of HepG2 cells with COS lactate salt significantly reduced ethanol-induced cytotoxicity and suppressed generation of reactive oxygen species. In addition, COS lactate salt dose-dependently increased acetaldehyde dehydrogenase (ALDH) activity in vitro and reversed the ALDH inhibition induced by daidzin. Furthermore, oral administration of COS lactate salt (200mg/kg) for 5 days significantly decreased the blood levels of alcohol and acetaldehyde in ethanol-treated mice. It was also demonstrated that hepatic mitochondrial ALDH activity was significantly increased in COS lactate salt-treated mice. Taken together, these findings indicate that COS lactate salt may have efficacy for the management of alcoholic hangovers.
圓筒形 tank의 T형 fillet용접부의 强度에 關한 硏究
方時桓 崇田大學校 1982 論文集 Vol.12 No.1
This paper reports the results of the experiment and numerical analysis about the behavior of the cylindrical tank loaded near the fillet weld toe by applying the moment to the in-plane of the T-section, Presupposing an abnormal loading. 1. The strain and stress are locally concentrated near the weld toe, and the stress is 61.91㎏/㎟ more than the yield stress 55㎏/㎟ when loading point displacement δ is 0.47㎜, and the strain is about 4.8 times as much as the yield strain when is 1.2㎜. 2. The stress and strain concentration factor of the elasto-plastic condition satisfies approximately the formula of Neuber's ?? in the range of the small displacement. 3. The plastic region of the annular plate is produced near the weld toe and, as the load increases, grows toward the center from the upper and lower surface and forms the plastic hinge at a plane a little distant from the weld toe.
Metastatic breast cancer from a hepatocellular carcinoma: a case report
Bang Hyewon,Kim Nam-Hee,Choi Seung Hye,Bae Si Hyun,Jung Eun Sun,Min Ki Ouk,Eom Yong Hwa 대한종양외과학회 2022 Korean Journal of Clinical Oncology Vol.18 No.2
Breast metastases from extramammary malignancies are rare. Here, we report a case of breast metastasis from hepatocellular carcinoma (HCC) after breast mass excision in a 63-year-old woman. A new breast nodule was noticed after transarterial chemoembolization, transarterial radioembolization, and stereotactic body radiation therapy for HCC. Breast ultrasound and core needle biopsy were performed to differentiate between the breast tumors. The biopsy result was invasive breast carcinoma, and wide excision of the breast was performed. The final pathological diagnosis was HCC breast metastasis based on histological findings and immunohistochemical staining results. After 9 months of follow-up, HCC and breast metastasis recurred. Despite palliative treatment, the patient died due to complications and general health deterioration. Although breast metastasis due to HCC is very rare, HCC breast metastasis should be considered when a new breast mass is discovered in a patient with a history of HCC for effective treatment and management.
