The purpose of this study was to determine factors related to the consumption of energy drinks among male and female high school students in Daejeon. The research data, derived from the self-administered questionnaire method, was collected from 664 students in fifteen high schools during the spring of 2016. A total of 542 complete questionnaires were analyzed (response rate: 79.8%). Approximately 73% of the students self-reported having consumed energy drinks, with a greater percentage of male (as opposed to female) students self-reporting as having done so. The most common reasons given for the consumption of energy drinks were to stay awake (54.8%), the good taste of the drink (28.0%), to concentrate during studying (17.2%), and to relieve fatigue (16.9%). The adverse effects were palpitation (59.3%), insomnia (35.6%), and experiencing difficulty in waking up (30.5%). More than two in three (67.8%) students who experienced adverse effects still consumed energy drinks. The average level of health consciousness was lower than 3 out of 5 points. The results of the logistic regression analyses indicated a positive relationship between monthly allowance (OR=1.01 for male and female students) and the consumption of energy drinks by both male and female students. Among the male students, freshmen (OR=0.23) were less likely to have consumed energy drinks than juniors. Male students' sleeping hours (OR=0.65) and perceived school life satisfaction scores (OR=0.63) were negatively associated with the consumption of energy drinks. In the case of female students, study hours (OR=0.83) and energy drinks consumption were negatively related. These factors affecting energy drinks consumption could be considered in the development of dietary education programs aimed at protecting high school students from the adverse health impacts of energy drinks.

도시 기혼여성의 간편가정식 선택속성이 구매에 미치는 영향

The purpose of this study was to investigate the purchasing behavior and selection attributes for Home Meal Replacement (HMR) and to identify the selection attributes affecting purchasing frequency and purchasing costs of married women living in a city. Among 837 questionnaires distributed to HMR married women consumers, 752 complete questionnaires (89.8%) were analyzed. The younger married women group showed higher frequency of purchasing HMR than the older age group. The 20s and 30s age groups showed higher purchasing costs for HMR than the 40s and older age groups. A higher proportion of employed married women purchased HMR three or more times per week and spent an average of more than 20,000 won per purchase in comparison with unemployed married women. HMR selection attributes were classified into five factors: 'taste and sanitation', 'economic efficiency', 'health and nutrition', 'convenience', and 'reliability and awareness'; mean scores of these factors' importance levels were 4.28, 3.93, 3.59, 3.54, and 3.50 out of 5 points, respectively. The importance level of 'taste and sanitation' factor was significantly greater as married women's age decreased. However, the importance level of 'health and nutrition' factor was significantly greater as married women's age increased. The results of the logistic regression analyses indicate that the 'taste and sanitation' and 'health and nutrition' factors affected frequency of purchasing HMR. The 'reliability and awareness' factor had the most significant impact on cost per purchasing HMR. Therefore, a product differentiation strategy according to married women's age and employment status should be applied. Product qualities and brand value should be improved to enhance competition in the HMR market.

1910~1920년대 전반기 안확의 `개조론`과 조선 문화 연구

류시현 ( Ryu Si Hyun ) 역사문제연구소 2009 역사문제연구 Vol.13 No.1

An Hwak(1886~1946) served a pioneering role in the area of historical and methodical studies of Korean culture, by authoring `Joseon`s art` and `Joseon`s literature` in the latter half of the 1910s. And in the wake of all the discussions regarding the `Reconstruction` of the early 1920s, he announced 『Argument of Reconstruction』, and participated in social movements as a staff member of the Joseon Youth Association. Later he concentrated upon authoring 『History of Joseon Literature』, 『History of the Joseon Civilization』, all studies related to the Joseon culture. An Hwak`s position in 『Argument of Reconstruction』, is between his own Joseon studies he announced through 『Hakji-Gwang』 in the mid-1910s, and his studies of the Joseon culture he announced in 1922 and 1923. An Hwak`s studies in those two periods maintained consistency, in terms of maintaining the cause of securing understanding of both the Western things and Joseon things, and also in terms of being a response to the foreigners` and especially the Japanese scholars` study of the Joseon culture. Yet crossing the `Reconstruction` period, An Hwak`s Joseon studies began to put more emphasis upon the cultural activities of the `ordinary people`, and he started to add the value of `righteousness and humanity` to the existing theme of `national quality of the Joseon people`, as well. His studies of the Joseon culture also proceeded from a civilization- comparative point of view. He argued the uniqueness and superiority of the Joseon culture, and his methodology that led him to that conclusion was similar to those of other contemporary cultural historians. Yet the object of comparison in his case was not the Eastern world, but instead the Greek culture and also the Western modern civilization. With this `universal` moral values, and his own emphasis upon `righteousness and humanity`, he was able to set himself apart from other nationalist historians and their overly strong sentiment of nationalism.

인체 관절각의 Variability가 태권도 지르기 속도에 미치는 효과

류시현 ( Sihyun Ryu ) 한국체육대학교 체육과학연구소 2019 스포츠사이언스 Vol.37 No.1

본 연구의 목적은 태권도 지르기 시 인체 관절각의 Lyanpunov exponent (LyE)가 지르고 당기는 속도에 미치는 영향을 살펴보는 것이다. 연구의 대상자는 태권도 품새 선수 18명 (나이: 20.8±2.4 세, 신장: 171.7±7.1 cm, 체중: 66.2±8.3 kg)으로 선정하였다. 태권도 앞굽이 바로지르기를 반복적으로 수행하는 과정에서 인체 관절각에 대한 LyE를 계산하고 LyE와 지르기 최대속도 간의 상관계수를 산출하였다. 그 결과는 다음과 같다. 첫째, 지르는 주먹의 최대 속도는 7.54±1.19 m/s로 나타났으며, 당기는 주먹의 최대속도는 7.76±2.51 m/s로 나타났다. 둘째, 상, 하지 관절각의 LyE는 전반적으로 근위에서 원위 부위로 갈수록 증가하는 경향을 보였다. 셋째, 지르고 당기는 주먹의 최대속도와 당기는 어깨관절각의 LyE 간에는 정적 상관관계(r=.498, r=.406)가 나타났으며, 당기는 주먹의 최대속도와 앞굽이 앞다리 무릎관절각의 LyE 간에는 부적 상관관계(r=-.451)가 나타났다. 위 결과를 바탕으로 빠른 속도의 지르기를 수행하기 위해서는 안정된 서기를 바탕으로 지르기를 수행해야 하며, 빠른 속도의 지르기를 수행한다면, 상지의 일관성은 다소 감소될 수 있다. The purpose of this study was to investigate Lyanpunov exponent (LyE) of joint angle during Taekwondo Jireugi and effects of LyE on velocity of Jireugi. Eighteen Poomsae athletes (age: 20.8±2.4 years, height: 171.7±7.1 cm, Body weight: 66.2±8.3 kg) participated in this study. The maximum speed of pushing fist was 7.54±1.19 m/s and pulling fist was 7.76±2.51 m/s. This study was trended to increase the LyE from proximal joint to distal joint. This study was shown positive relation between the maximum speed of pushing and pulling, and the LyE of pulling shoulder joint (r=.498, r=.406). This study was shown negative relation between the maximum speed of pulling and the LyE of forward knee joint (r=.451). Based on the results of this study, it is considered that the stability of stance are directly related to the speed of Jireugi in Taekwondo.

김대중의 역사인식과 한국사 이해의 특징

류시현 ( Ryu Sihyun ) 호남사학회(구 전남사학회) 2020 역사학연구 Vol.80 No.-

김대중은 한국 현대사를 대표하는 정치가이자 국정 책임자인 대통령을 지냈던 인물이다. 그의 활동과 영향력과 관련해서 외교와 통일을 포함한 정치 영역에서의 연구 성과는 많이 축적되어 있다. 하지만 상대적으로 정치적 활동과 결정의 기반이 되었던 그의 사상에 관한 연구는 적었다. 따라서 김대중의 정치활동에 기반이 되었던 그의 역사 인식이 어떠했는가에 관한 연구가 요구된다. 김대중은 아놀드 토인비와 그의 『역사의 연구』에서 많은 영향을 받았다. 인류문명사의 ‘도전과 응전’, ‘창조적 소수자’의 역할 등의 개념을 한국 역사 이해에 적용하고자 했으며, 민족사의 적용과정에서 형성된 역사 진행과정에 관해 ‘낙관’적 전망을 가지게 되었다. 또한 민중 주체의 개혁을 긍정적으로 이해했다. 세계사와 한민족사의 경험에 기초한 역사 발전에 관한 믿음은 민족주의에 관한 유연한 인식이 가능하게 만들었다. 그리고 민족사에 관한 이해는 민주주의와 통일이란 과제를 해결하기 위한 방안으로 활용했다. 역사를 좋아하고, 역사의 심판을 중요시 했던 김대중은 자신의 역사관을 그의 정치활동의 정신적, 사상적 자산으로 삼았다. Kim Dae-jung a politician who represents the modern Korean history and national responsibility, a former president. Reflecting his influence, many research achievements in the political area including diplomacy and unification have been accumulated. However there was less researches on his ideas which were relatively the basis of political activities and decisions. Therefore his A Study on the historical perception as well as Kim Dae-jung's political activities is required. Arnold Toynbee and his book A Study of History affected to Kim Dae-jung. He wanted to apply the role of "challenge and retort" and "creative minority" in the history of human civilization to understanding Korean history. The "optimistic" outlook on the progress of history, which was formed during the application of national history was given. And positively understood the reform of the people's subjects. Belief in the development of history based on the experience of world history and Korean history has made it possible to have a flexible perception of nationalism. And the understanding of national history was used as a way to solve the challenges of democracy and unification. Kim Dae-jung regards history as his mental, spiritual assets of his political activities.

1910년대 최남선의 문명ㆍ문화론과 조선불교 인식

류시현(Ryu See Hyun) 한국사연구회 2011 한국사연구 Vol.155 No.-

?;?;In early 20th century Korea, the nationalist cultural movement aimed at the enrichment of cultural potential through publishing newspapers and magazines. It was also championed by Korean nationalists struggling against Japanese forces in Korea. Benedict Anderson emphasizes “print-capitalism” as formative of the nationally imagined community. Western culture was imported to Korea at the onset of the 20th century. Therefore, we need to look for the effect of Western thoughts contributing to the culture of the colonized. If this is indeed the case, we need to examine what kinds of publishing activities were conducted, how these served to establish a national identity, and the purposes and educational backgrounds of the publisher’s themselves.<br/> ?;?;Ch’oe’s career as a publisher, editor, and writer, however. is very suggestive for our study of the role of the publishing business played in early 20th-century Korea. Besides establishing Sinmunkwan (the House of New Culture), which was focused on publishing popular magazines and domestic and foreign novels. I examined Ch’oe’s publication activities of the I910s through the articles on Maeilsinbo (newspaper). Firstly, by investigating Ch’oe’s staying in Japan during the middle of 1910s. I identify why he emphasized “modernity” and culture especially the publishing culture,<br/> ?;?;Secondly, I confirm Ch’oe’s effort to identify Korean culture through the examination of the Korean Buddhism, Lastly, through the scrutiny of the Ch’oe’s focus both traditional culture and new civilization of between Western thoughts and Japanese thoughts, I clarify his reinvention of ‘new’ Korea identity by way of Korean Studies. Analyzing these three topics would like to help deepen our understanding of Korean nationalists’ cultural activities in the early 20th century.

Multiply-Translated Modernity in Korea

Ryu Si-hyun(류시현) 고려대학교 한국사연구소 2011 International Journal of Korean History Vol.16 No.2

19세기 말~20세기 초반, 서구 사상의 번역은 동아시아 근대와 민족주의 형성과 밀접하게 연관되었다. 어떠한 서양 책을 선택해서 번역하는가에 여부에는 서구 열강의 정치적 영향력과 밀접하게 연결되었다. 일본의 경우 페리에 의한 ‘개항’(1854년)을 전후해서 서구 사상의 주된 번역 대상어가 된 것은 화란어가 아닌 영어였다. 리디아 리우는 이를 ‘번역된 근대’라고 규정했다. 본고에서는 중국과 일본의 경우 ‘번역된 근대’를 경험했다면, 식민지 조선은 일본과 중국에서 번역한 서양서적을 재차 번역해서 수용한 ‘중역된 근대’를 경험했다는 가설에서 출발했다. 그리고 이를 분석하기 위한 텍스트로 사무엘 스마일즈의 Self-Help의 일본과 한국의 번역과정을 살펴보았다. 그리고 일본과 식민지 조선의 번역과정에서 시대적 상황은 물론 번역가, 독자에 관해서도 함께 고려했다. 번역은 번역자와 독자의 의도에 따라 완역, 축역, 번안 등의 방식으로 이루어졌으며, 이는 이 책의 한글 번역본인 〈자조론〉(1918년)에도 적용될 수 있다. 번역가인 최남선은 영어 원전은 물론 일본어 번역본과 달리 번역자의 의도를 강하게 투영했는데 첫째, 식민지 조선의 전통적인 요소를 부가하고 둘째, 일제의 검열을 염두에 두었으면 셋째, 계몽의 차원에서 생산자와 공장 경영자 등 ‘경제적 영웅’을 강조했다. 이를 통해 일제와 정신적인 측면뿐만 아니라 물질적이고 경제적인 측면에서도 경쟁하고자 했다. During the late 19<SUP>th</SUP> century and early 20<SUP>th</SUP> century, the translation of the Western books was closely connected to East Asia’s modernity and nationalism. Choosing which foreign texts would be translated and in what way was also dominated by a “word-power relationship.” I apply the concept of “translated modernity” in China and Japan to the idea of multiply-translated modernity in colonized Korea, because translation of texts originated from relationships between the West and the East, between both China and Japan and Korea, between the colonizer (Japan) and the colonized (Korea), and in the process of translation and re-translation. Trough Self-Help and its translations into both Japanese and Korean, I have examined translators, readers, and the contents of this book, the so-called “modern hero.” The characteristics of multiply-translated modernity in Korea are like this: First, the translation of Western thought, sometimes combining it with traditional texts, was used by translators to invoke Korean modernity. Second, the needs and desires of Korean readers in the1910s were multiple, based on their social status and political opinions. Third, translated books were utilized for competing with imperialism in the spiritual domain as well as in the material domain. The notion of the hero was useful to resist imperialism in the spiritual domain and the notion of a “modern hero” specifically was useful in the material domain.

일제강점기 현상윤의 문명론과 조선 문화 연구

류시현 ( Ryu Si-hyun ) 전남대학교 호남학연구원 2017 호남학 Vol.0 No.62

1893년 출생인 현상윤은 일본 유학생 출신이자 교육가, 사상가였다. 그는 근대 문명의 소개에 앞장선 문명개화론자이자, 『조선유학사』와 『조선사상사』를 집필한 조선 문화와 역사 연구자이기도 했다. 근현대에 걸친 그의 학문적, 사상적 영향에 관한 많은 선행 연구가 이루어졌지만, 일제강점기와 해방 후를 연결시키는 1930년대 조선 역사와 문화에 관한 연구가 깊이 이루어지지 않았다. 본고에서는 우선 1910년대 근대주의자 현상윤에게 제1차 세계대전과 ‘개조론’의 영향이 컸음을 확인했다. 3·1운동 이후 현상윤은 1930년대 조선 역사와 문화에 관한 글을 발표한다. 그는 민족주의사학자들의 ‘민족사’의 강조와 일정하게 거리두기를 시도했다. 그리고 1930년대 현상윤의 조선학운동 참여와 실학 연구에 관한 검토를 통해 해방 후 『조선유학사』의 유학 이해의 연속과 단절을 살펴보았다. 이를 통해 근대주의자이면서 조선 문화 연구자인 현상윤의 전통에 관한 이해의 균열을 살펴보고자 했다. ‘개조론’과 3·1운동이 조선 문화 연구의 계기가 되었으며, 1930년대 조선학운동 참여와 실학 연구가 해방 후 연구의 학문적 배경이 되었다고 판단된다. 향후 그의 근대와 전통에 관한 이해를 당대 유사한 학문적 경험을 지녔던 일본 유학생 출신이면서 조선학 연구자들과 비교하고자 한다. This article exams the thoughts of Hyeon Sang-yun, one of colonial modern intellects of the Japanese Colonized period, who traversed Korean culural tradition and the Western modernism. He studies modern education at Bosung school when he was a teenager, and studied abroad at Waseda University in Japan. During his twenties’ he had a negative view about all oriental culture an civilization including Confucianism which introduced in China. After the end of the First World War, there was raised the theory of Re-construction which goals are against War and keeping peace. He participated in the March 1 Independent Movement in 1919. And he also actively interested in Korean culture and history based on the belief to the Korean people. As he witnessed the crisis of modern civilization in the West during the 1930’s. he have an interest agin in Confucianism. Especially he defined Silhak(the Korean Realist School of Confucianism) as the School of Pragmatics. Nonetheless, he still maintained a critical attitude toward the Korean Neo-Confucianism during the Chosn dynasty. Therefore, Hyeon tried to find a way to overcome the present conditions through criticizing the political factions at the late of the Chosun period and introducing the Western modernism and famously evaluated Korean cultures. However, his modernized version of confucianism couldn’t get much further during the colonial period. Nonetheless, after the Korean liberation in 1945, he tried to find a new way for the high values of Korean Neo-Confucianism.
