본 연구는 가열하여 섭취하는 냉동식품 중 빵류 20건 및 서류가공품 30건과 식품접객업소의 조리식품 중 감자튀김 20건을 대상으로 가열조리에 따른 아크릴아마이드 함량을 분석하였다. 에어프라이어를 이용한 냉동식품의 조리 전·후 아크릴아마이드 함량과 식품접객업소 조리식품의 아크릴아마이드 함량을 LC-MS/MS를 이용하여 분석하고 비교하였다. 아크릴아마이드 함량은 에어프라이어 조리 후 빵류 4건에서 0.167-0.401 mg/kg, 서류가공품 24건에서 0.071-0.694 mg/kg으로 나타났으며, 식품접객업소 조리식품은 모든 제품에서 0.118-0.977 mg/kg으로 나타났다. 이 중 국내 아크릴아마이드 권장규격인 1 mg/kg을 초과한 제품은 없었다. 하지만 유럽연합의 benchmark level (0.5 mg/kg)을 초과한 냉동 제품 3건을 튀김기 조리법으로 가열 조리하였을 때, 서류가공품 1건이 국내 권장규격을 초과하여 1.83 mg/kg으로 검출되었다. 아크릴아마이드에 대한 국내 노출량이 증가하는 추세이므로 아크릴아마이드 저감화를 위해 지속적인 평가와 관리가 필요한 것으로 판단된다. This study aimed to investigate the acrylamide content in frozen food products after cooking. Twenty samples of bread (Group 1) and 30 samples of processed tuberous and corn vegetable products (Group 2) were selected. Acrylamide levels were quantified using liquid chromatography tandem-mass spectrometry (LC-MS/MS). The frozen food samples were heated using the air fryer cooking method according to the product packaging and were compared to ready-to-eat French fries (Group 3). The results showed that the acrylamide content was the highest in group 3, followed by that in group 2 and group 1. The acrylamide content of all the samples was found to be within the domestic recommended standard of 1 mg/kg. However, when the samples that exceeded EU benchmark level (0.5 mg/kg) were selected and cooked using the deep-fat frying method according to the product packaging, one of them showed the acrylamide content of 1.83 mg/kg, which exceeded the domestic recommended standard. The present study highlights the need for continued evaluation and management to reduce acrylamide contents in frozen foods, as increasing domestic exposure to acrylamide is concerning.

이유진,Lee, You-Jin 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.8

연구 목적은 20대 금융 애플리케이션 사용자의 비대면 글말 용언으로부터 사용자 경험 디자인(UX)의 확장 의미를 추출하는 데 있다. 연구 범위는 20대 남녀 20명의 비대면 글말 일상 언어이며, 연구 방법은 사용자의 용언을 중심으로 사용 속성을 범주화(Categories)하여 20대 사용자 중심의 의미를 도출하는 것이다. 연구 결과 20대 금융 플랫폼 애플리케이션 사용자의 사용 의미는 통합의 의미, 신뢰의 의미, 지속의 의미, 정보 인지와 정보 접근의 의미로 요약되었다. 또한, 사용자의 사용 속성은 보안성, 친숙성, 접근성, 작동 편이성, 시인성으로 집약되었다. 각각의 속성은 보안, 정보, 브랜드, 디자인과 융합된 의미 범주에서 나타났다. 종합하면, 용언 중심의 사용자 의미 분석은 기존의 객관적 의미 분별 측정에서 파악할 수 없었던 사용성 평가 문제를 보완하는데 효과적임을 알 수 있었다. The purpose of the study was to induce meaning of the UX design from users' interview. The study covers interviews from 20 untact finance application users in their twenties in written form. It aims to examine previous studies on UX design and to overcome their shortcomings by categorizing usability qualities focusing on verbs used in the interview. The followings are the result: Usability of UX design can be summarized into Unity, Trust, Persistency, Recognition and Approachability of the information to the 20 users in their twenties. As for the data earned from interviews focusing on verbs, usability included Security, Familiarity, Accessibility, Convenience of Operation and Visibility. Each of the qualities fell into related categories such as Security, Information, Brand and Design. In conclusion, analysis based on verb choices led to better understanding of the user-based experience compared to using objective means in previous studies and can be a suggestion to make up for errors in the former evaluation process.

대전통과 소전통의 이중 변주

李有鎭(Lee, You-jin) 중국어문학연구회 2016 중국어문학논집 Vol.0 No.96

This paper examines a topography of Chinese academic discourse on ‘great tradition and little tradition’(1980’s-1990’s), which is a part of the research of “Crucial Aspects of Chinese Academic Discourse on ‘Great Tradition and Little Tradition’ and Its Meaning”. The goals of this research are to clarify national identity-building in today’s China. Robert Redfield presented the concept of ‘little tradition and great tradition’. The twin concept stands for ‘high and low culture’ or ‘classic and folk culture’ or ‘learned and popular culture’. The core of this paper is to describe and analyze different concepts of ‘little tradition and great tradition’ in China. For this purpose, this paper investigates the opinions of some scholars on the concept of ‘little tradition and great tradition’. Yu Yingshi, Li Yiyuan, Chen Lai, Ge Zhaoguang, and Fei Xiaotong, these scholars focus on either ‘great tradition’ or ‘little tradition’. In my view, it is all a question of ‘tradition’ handed down within in their community. Tradition is a flexible concept. And of course, the same is true for ‘little tradition and great tradition’. The social circumstances at the time are the key drivers of the change related to these concepts. This is why I contextualize Chinese academic discourse on ‘great tradition and little tradition’(1980’s-1990’s) within a sociocultural framework. The two traditions are interdependent. Dual variation of great tradition and little tradition circulates on a Möbius strip named ‘Tradition’.

중국의 내셔널리즘 형성과 량치차오의 역사인식

李有鎭(Lee You-jin) 중국어문학연구회 2010 중국어문학논집 Vol.0 No.62

This essay aims to examine the historical awareness of Liang Qichao, with focus on the formation of Chinese nationalism from the late 19th century the early 20th century. After the failure of the Hundred Days’ Reform, Liang devoted himself to the nation-building project through writing the periodical essays, and had become the most influential political journalist. Consequently, Liang played a significant role in the formation of Chinese nationalism at the turn of the 20th century. Embarking on the project of nation-building, Liang Qichao paid special attention to the force of history. So, during his exile in Japan, Liang wrote New History, launching attacks on traditional historiography and enthusiastically calling for a ‘new history’. In New History from the very beginning, he emphasized that history is the origin of patriotism. He proposed to write a new history, namely national history, to replace the traditional dynastic history. The historical awareness of Liang Qichao shows us the intimate relationship between the nationalism and the evolutionary history. In Liang’s belief, the China needed to come up with the social Darwinism of the survival of the fittest to be rich and strong again. To that end, he purposed to make a nation as the subject of the linear history, and to promote the idea of ‘new citizen’. Most of the contemporary Chinese intellectuals, as Duara points out, “sought to narrate their history in the linear, teleological mode and thus performatively propel Chinese history into the progress of universal History.” It is lamentable that history is still medium for the production of the nation in nation-states supporting the concept of a competitive Darwinian world.
