  • Fermented anchovy was used to investigate its effects on the formation of lipid peroxide and the activities of epoxide or free radical generating enzyme in vitro in bromobenzene-treated rats. All solvent fractions from fermented anchovy not only showed the strong antioxidative activities on linoleic acid autooxidation, but also reduced bromobenzene-induced hepatic lipid peroxidation. The activities of aniline hydroxylase and aminopyrine N-demethylase elevated by bromobenzene were recovered to the level of normal rats by adding the solvent fractions of fermented anchovy. But, xanthine oxidase and aldehyde oxidase activities were not affected by fermented anchovy. These results suggest that reduction of the bromobenzene-induced hepatic lipid peroxidation is caused by inhibition on the epoxide formation, not on free radical generation.

  • This study analyzes the revision bills of the National Assembly Law in the 19th National Assembly in which the National Assembly Advancement Act was enacted, with the question "who are involved in the revision of the procedural rules, and what motivates them?" The cosponsor network analysis focusing on primary sponsors of the revision bills shows that the network was constructed by party affiliations. A small number of members with high degree centrality attempted to cooperate with each other at the cosponsoring stage, but the legislation did not pass through the related committee. In addition, this study tests the four competitive hypotheses (the committee hypothesis, the distributive politics hypothesis, the ideological distance hypothesis, and the partisan affiliation hypothesis) about the motivation to propose amendments by using the regression models which include newly measured variables. Only the committee hypothesis and the partisan affiliation hypothesis are empirically supported. This implies that partisan consideration is still significant in amending the National Assembly Law even after the National Assembly Advancement Act, and thus party leaders' willingness to seek bipartisan compromises is at the heart of problem-solving.

  • Hwang Hee (1363~1452), a well-known politician in the beginning of Joseon Dynasty, tremendously contributed to opening the glorious civilization during the reign of King Sejong. He was a public servant canonized in the Jongmyo Shrine and a good example of clean government officials in the Joseon era. There were two requests from scholars of 8 provinces across the country to ask his tablet to be enshrined in the Confucian shrine. As a matter of fact, historical evaluation as well as his status is somewhat extraordinary, but his appraisal during his living times was not consistent according to the annals of Joseon like "Sejong Chronicles". Many of his corruptions and unjust behaviors were shown in the annals. It is hard to accept all of them as truth. There are some questions raised about his character, but also some as intentionally bad judgments. However they should be respected now since the authors were trying to write objectively based on their consciousness. Hwang Hee was highly evaluated and popular among bureaucrats because of his generosity. On the contrary, his generosity was so big that he had problems dealing with his family matters according to an official writing historic chronicles. I think this judgment explains well the reason why then some raised questions about his reputation. This goes well with Confucian's saying, "Each fault by humans has a pattern. Seeing one's fault will let you know the one's personality."

  • We aimed to produce a potent β-glucuronidase inhibitor from wild yeast that could inactivate toxic substances in the colon. Culture supernatants and cell-free extracts of non-pathogenic wild yeasts were prepared and their β-glucuronidase inhibitory activities were measured. Cell-free extract from Candida oleophila WP5-19-1 showed the highest β-glucuronidase inhibitory activity (49.0%). The β-glucuronidase inhibitor was maximally produced (IC50 value; 8.4 mg) when C. oleophila WP5-19-1 was cultured in potato dextrose medium containing 5% dextrose (initial pH; 6.0) at 30℃ for 24 hours. β-glucuronidase inhibitor of C. oleophila WP5-19-1 was partially purified by trypsin hydrolysis, ultrafiltration (3 kDa), and Sephadex G-50 filtration. The partially purified β-glucuronidase inhibitor was stable from 30℃ to 60℃ and at pH 6.0 9.0, and showed residual inhibitory activity of about 80%.

  • Object : The purpose of this study was to evaluate the relationship between pattern identification (PI) and stroke risk factors, such as hypertension, diabetes mellitus, dyslipidemia, stroke history, obesity, abdominal obesity and metabolic syndrome. Methods : 46 patients with acute ischemic stroke were recruited from May 2012 to November, 2012. We analyzed the data of 32 patients, and pattern identification was identified by resident and specialist of Korean medicine. We analized patient's PI and risk factor by Fisher's exact test. Results : We found that Dampness-phlegm group was more related with patient's metabolic syndrome than non Dampness-Phlegm group. And Yin deficiency group had less relationship with patient's metabolic syndrome, obesity, abdominal obesity and dyslipidemia than non Yin deficiency group. Conclusions : According to the analysis, these results provide evidence for relationship between the Dampness-phlegm group, Yin deficiency and metabolic syndrome.

  • Seafood is a major source of protein in many countries and its consumption is increasing. In Korea, consumption of seafood is increasing, but self-sufficiency rate is decreasing, and the importance of safety management is increasing as the amount of imported seafood increases. There are hundreds of species of aquatic products imported into Korea from over 110 countries, and there is a limit to relying only on the experience of inspectors for safety management of imported aquatic products. Based on the data, a model that can predict the customs inspection results of imported aquatic products is developed, and a machine learning classification model that determines the non-conformity of aquatic products when an import declaration is submitted is created. As a result of customs inspection of imported marine products, the nonconformity rate is less than 1%, which is very low imbalanced data. Therefore, a sampling method that can complement these characteristics was comparatively studied, and a preprocessing method that can interpret the classification result was applied. Among various machine learning-based classification models, Random Forest and XGBoost showed good performance. The model that predicts both compliance and non-conformance well as a result of the clearance inspection is the basic random forest model to which ADASYN and one-hot encoding are applied, and has an accuracy of 99.88%, precision of 99.87%, recall of 99.89%, and AUC of 99.88%. XGBoost is the most stable model with all indicators exceeding 90% regardless of oversampling and encoding type.

  • The purpose of this study was designed to develop an questionnaire for healthy aging. The subjects of this study were total 335 people who participated in regular exercise and went to welfare centers in Seoul. The validity and reliability were tested for verifying the developed questionnaire for healthy aging. The data were collected between June 12, 2006 and October 27, 2006. The mean, standard deviation, kurtosis, skewness, reliability, exploratory factor analysis and confirmatory factor were analyzed for statistical purpose using by SPSS-Win 12.0 program. The results were as follows; First, to obtain content validity, the results of previous research and the value system responses were submitted to a judgement group. Second, the results of the factor analysis of the 20 items making up the questionnaire were classified into the following 3 factors; physiological health(6 items), cognitive-mental health(6 items), social-support health(8 items). Third, the reliability of the questionnaire for healthy aging was 0.891(Cronbach's alpha). In the factor analysis Cronbach's alpha correlations for the 4 factors ranged from 0.642 to 0.885. Fourth, the results of confirmatory factor analysis, all the index values(NFI, RFI, CFI, Delta 2 IFI) were close to 1. Thus, this questionnaire demonstrated good reliability and validity and therefore it was an appropriate measurement of healthy aging.
