Recently, concerns about the volatile hazardous compounds including acetaldehyde, methanol, and fusel oils in alcoholic beverages, which cause hangover such as headache and dizziness after consumption, have been raised. The volatile hazardous compounds might also lead to an increased incidence of liver diseases and even cancers with a high consumption of alcoholic beverages. Acetaldehyde is a volatile compound naturally found in alcoholic beverages and used as flavor in many foods. However this is also regarded as possibly being carcinogenic to humans. Furthermore, acetaldehyde with alcoholic consumption is recently classified as Group 1, carcinogenic to humans. On the other hand, methanol is generated from demethoxylation of pectin by pectinolytic enzyme during alcoholic fermentation. Higher alcohols occur naturally in alcoholic beverages as by-products of alcoholic fermentation and are generally regarded as important flavor compounds. In the current study, we reviewed on the health concern, maximum levels, analytical methods, and current levels of hazardous volatile compounds in alcoholic beverages.

연료분출을 수반하는 원통형 보염기 후류에 형성되는 확산화염에 대한 이온전류의 특성과 화염의 안정범위를 측정, 분석함으로써 연소특성을 고찰하였다. 난류강도가 큰 경우의 화염일수록 화염의 안정성은 악화되며, 화염내 중앙의 평균 이온전류값이 가장 높은 값을 갖는 영역은 블로오프 직전상태에 비해서 안정시의 경우 더욱 하류측에 존재한다. 난류의 정도가 강한 화염의 경우 국소적으로 반응이 활발한 화염 덩어리가 빠른 속도로 이동하며, 난류의 정도가 강한 화염의 경우에는 반응이 완만한 화염 덩어리가 저속으로 이동한다. 재순환영역에서 주류유동측으로 이동함에 따라 자기상관계수의 저하가 빨라지고 난류 시간스케일이 작아지며, 부염기 직후에서 하류로 이동함에 따라 자기상관계수의 저하가 늦어지고 난류시간스케일이 커진다. 주류공기에 강한 난류를 가하지 않은 경우에는 큰 난류시간스케일에 대응되는 저주파수 특성이외에도 작은 난류 시간스케일에 대응되는 고주파수 특성이 나타나며 , 주류공기에 강한 난류를 가한 경우에는 큰 난류 시간스케일에 대응되는 저주파수 특성이 나타난다.

Recently, a breakthrough has been made in the NLP area by Transformer techniques based on encoder-decoder. However, this only can be used in mainstream languages where millions of dataset are well-equipped, such as English and Chinese, and there is a limitation that it cannot be used in non-mainstream languages where dataset are not established. In addition, there is a deflection problem that focuses on the beginning of the document in mechanical summarization. Therefore, these methods are not suitable for documents with flows such as fairy tales and novels. In this paper, we propose a hybrid summarization method that does not require a dataset and improves the deflection problem using GAN with two adaptive discriminators. We evaluate our model on the CNN/Daily Mail dataset to verify an objective validity. Also, we proved that the model has valid performance in Korean, one of the non-mainstream languages.

컴퓨터가 출현한 이후, 컴퓨터를 원래의 목적이 아닌, 다른 용도로 사용하려는 시도는 꾸준히 있어왔다. 컴퓨터 게임(computer game) 분야는 그러한 시도들 중에서 상업적 성공을 거둔 것들 중의 하나이다. 이 분야는 몇몇 비주류 프로그래머들로부터 시작되었지만, 점차 상업적인 가능성을 보여 주었고, 꾸준한 발전을 거쳐, 최근에는 수백 명이 몇 년에 걸쳐 전력 투구하는, 대형 프로젝트들로 변모하고 있다. (중략)

최근 국내시장에 판매되고 있는 막걸리의 종류는 매우 다양하며, 주류시장에서도 큰 수입원으로 부각되고 있다. 또한 국내뿐 만아니라 해외수출 비중도 높아지고 있으며, 주류관련 기업에서는 고급화 전략으로 마케팅을 하고 있다. 막걸리와 더불어 상품화 비중이 높아지고 있는 기능성 주류는 미용, 건강, 갈증해소 등 다양한 효능을 가지고 있으나, 일반적인 주류의 홍보에 비해 상대적으로 미비한 상태이다. 본 연구의 일부분으로 제작되는 막걸리는 피부미용, 면역력 강화, 뇌기능 개선 등의 효과를 갖는 감태를 주성분으로 하여 제조한 기능성 주류이다. 따라서, 본 연구에서는 감태를 이용한 기능성 막걸리의 제조과정과 막걸리의 특성을 파악한 효과적인 홍보 방안을 위한 콘텐츠 설계 및 개발에 대한 제안한다.

Objectives: The objective of this study was to identify the association of food intake with bio-physiological indicators: blood pressure, body mass index (BMI), waist/hip ratio (WHR), cholesterol and urine sugar among rural people. Methods: The subjects were 890 inhabitants from 14 towns of G County in Honam province. Data were collected by interview and self-reported with structured questionnaires from April 6th to 30th 2005. Data were analyzed with the frequency, percentage, t-test, $x^2$-test, ANOVA, Scheffe test and ANCOVA using SPSS 12.0 program. Results: Pre-hypertensive and hypertensive group was 27.0%, overweight and obese 27.1%, more than 0.90 in WHR 42.0%, more than 201 mg/dl of cholesterol 23.9%, and positive urine sugar was 8.7% in general. Among eleven food groups, fruit intakes were more effective in normotensive group than in the others. Vegetables, liquors, and milk products were 0.90 WHR more effective than the others. Milk products and liquors in BMI, and grains, beans and seaweed in low cholesterol group were more effective than the others. Conclusions: Bio-physiological indicators are related significantly only with fruits, milk products, meats, cereal and liquors among eleven food categories. Further study on the relationship between food intake, physical activities, smoking, drinking and lifestyle with bio-physiological indicators are suggested.

This study explores the characteristics and roles of non-textual elements in secondary mathematics textbooks in the United States and South Korea, using a conceptual framework that I have developed: variety, contextuality, and connectivity. Analyzing five U.S. standards-based textbooks and 13 Korean textbooks, this study shows that although non-textual elements in mathematics textbooks are free of literal language, they exhibit different emphases and reflect assumptions about what is important in learning mathematics and how it can be taught and learned in a particular societal context (Mishra, 1999; Zazkis & Gadowsky, 2001). While there are similar patterns in the use of different types of non-textual elements in textbooks from both countries, different opportunities are provided for students to learn mathematics between the two countries.

To use the filter materials for selective removal of carbonyl compounds in cigarette mainstream smoke, hydrazine such as 2,4-dinitrophenylhydrazine (2,4-DNPH) and dansylhydrazine (DAH) impregnated adsorbents were prepared with perchloric acid or phosphoric acid as an accelerator in hydrazone formation reaction. Changes of molecular structure and morphology of adsorbents in various of impregnator were investigated by FTIR/ATR and SEM. Impregnation amount caused by reaction time, acid type and impregnation reagent, and the adsorption properties of carbonyl compounds in cigarette mainstream smoke were studied. Amounts of impregnation increased with increasing reaction time. The removal amount for vapor phase carbonyl compounds by 2,4-DNPH impregnated adsorbent was higher than that of dansylhydrazine impregnated adsorbent. The selectivity of 2,4-DNPH impregnated polyacrylic type adsorbent was superior to those of other adsorbents. This result indicates that the 2,4-DNPH impregnated polyacrylic adsorbent is applicable to cigarette filter material because of its fast reactivity and porosity.
