최승윤,배상희,송유한,Choi Seung Yoon,Bae Sang Hee,Song Yoo Han 한국응용곤충학회 1970 한국식물보호학회지 Vol.9 No.1

본 시험은 유기인계 살충제인 Terracur P입제 및 Lebaycid 입제와 유기염소계 살충제인 상감마입제$(\gamma-BHC 입제)$를 수면시용 하였을때 수도요해충인 이화명충, 끝 동매미충, 애멸구 및 흰둥멸구에 대한 동시방제가능성과 방제적기를 구명하고 약제간의 방제효과를 비교코저 실시하였다. 얻어진 시험결과는 다음과 같다. 1) 약제처리후 부화직후 이화명충 접종 시험에 있어서 상감마와 Terracur P는 높은 살충율을 보였으나 Lebaycid의 살충율은 낮았다. 約 $50\%$ 살충력 잔효일수에 있어서 상감마는 8-14日이었고 Terracur P는 6일간이었다. 2) 당초 계획된 방제적기에 관한 정보는 얻을 수 없었다. 즉 주어진 일간격이 좁아 유의한 차를 얻을 수 없었다. 3) 1,2화기 이화명충에 대한 방제효과는 Terracur P=상감마>Lebaycid의 순이었다. 4) Terracur P와 Lebaycid 입제의 처리는 끝동매미충의 방제효과가 좋았으나 상감마$(\gamma-BHC 입제)$의 방제효과는 기대할 수 없었다. 끝동매미충에 대한 Terracur P와 Lebaycid입제의 잔효력은 30일 이상이었다. 5) 애멸구와 흰등별구에 대한 시험은 충의 서식밀도가 낮기 때문에 약제간 방제효과를 얻을 수 없었다. 6) 공시약제중 Terracur P와 Lebaycidd입제는 이화명충과 끌동매미충의 동시방제제로서 사용할 수 있을 것 같다. This experiment was conducted to find out the simultaneous control effect of granulated insecticides on the several major rice insect pests in Korea. The granulated insecticides used were Terracur P$5\%$ (one of the phosphoric insecticides), Lebaycid $5\%$, and Sang-gamma (gamma-BHC) $6\%$. Those insecticides were broadcasted by hand on the paddy field at the ratio of 3kg. in June and 4kg. in August per 10 a, and the date of insecticidal application was based on the maximum moth occurrence of the rice stem borer in 1969. The rice insect pests tested in this study were rice stem borer (Chilo suppressalis W.), green rice leafhopper (Nephotettix bipunctatus cincticeps U.), smiller brown planthopper (Laodelphax striatellus F.), and white back planthopper (Sogotella furcifera H.). For the study of residual effectiveness of the insecticides, the rice stem borer larvae just hatched from the eggs were installed on the sheath of rice plants collected from the paddy field after insecticidal treatment, and the mortality was made at 48 hours after installation. High mortality was observed in Terracur P and Sang-gamma treatments and low mortality in Lebaycid treatment. The duration of residual effects giving about 50% mortality was about 14 days in Sang-gamma and about 6 days in Terracur P treatments. The study on the effectiveness of the insecticides to the rice stem borer in the paddy field was made by the number of dead blades and white heads of the rice plants injured by the larvae, and the number of survival larvae in the straws after crop harvest. The order of insecticidal effectiveness to the rice stem borer was Terracur P=Sang-gamm>Lebaycid. The study on the effectiveness of the insecticides to the leafhoppers and planthoppers in the paddy field was made by the population density by sweeping (5 times) at the given day intervals after treatments. Terracur P was highly effective for the control of the green rice leafhoppers and Lebaycid was moderately effective, but Sang-gamma seemed not to be effective. The effectiveness of the insecticides tested to the planthoppers was not clear, and it seemed to related with the low insect population density. Study on the determination of proper timing of insecticidal application was not also made clear, and it seemed to be short in the range of day intervals in the insecticidal application. For the study on the control effects of the rice insect pests, rice yield per 100 hills per plot was observed. There was no statistically significant difference among the treatments in rice yields, but the order of yield (Terracur P>Sang-gamma>Lebaycid>Control) was paralleled with the tends of control effects above mentioned. In a view point of simultaneous control of the rice stem borers and green rice leafhoppers by the application of granulated insecticides, Terracur P and Lebaycid were more effective than Sang-gamma which have been used.

오판진(Oh, Pan-jin),유상언(Yoo, Sang-eon) 학습자중심교과교육학회 2022 학습자중심교과교육연구 Vol.22 No.7

Objectives The purpose of this study is to analyze how to hold a pencil in the first grade of elementary school Korean and to find ways to help students write correctly. Methods A case study method was used among the qualitative studies, and interviews with Yoo Sang-eon for a single case of how to hold a pencil, Hangul files related to his claims, YouTube materials, student handwriting materials, and testimonials were used in this study. Textbooks and teacher s guides were analyzed in a multi-layered manner, along with texts and letters. Results As a result, it was found that there was a problem with the position of the finger guiding in the current 2015 revised curriculum for the first grade textbook. In other words, if you look at the position of your fingers when writing, holding a pencil while holding your thumb and index finger in a circle is not the optimal way. Also, it is not appropriate to place your elbows on the desk when writing, so it is a guideline that needs to be corrected. On the other hand, Yoo Sang-eon s method of holding a pencil is a better way to help students write correctly. Here s how to hold a pencil correctly, as he suggests. First, put the tip of the thumb and middle finger together to make a round shape, and then place the pencil on the nail area of the middle finger and the area next to the bone where the index finger begins. Second, lift your thumb upwards, bend it at a right angle, and press the pencil gently from above. Third, bend the forefinger close to a right angle and put it lightly between the thumb and middle finger without straining. Fourth, write in such a way that the wrist or arm where you are writing extends slightly over the edge of the desk. Conclusions If you write according to the shape and position of the finger holding the pencil as suggested by Yoo Sang-eon, the force of the finger applied to the pencil is maintained evenly, so that you can write more correctly. 목적 이 연구의 목적은 초등국어 1학년의 연필 잡는 법을 분석하고, 학생들이 바른 글씨를 쓰도록 돕는 방안을 모색하는 데 있다. 방법 이 연구에서는 질적 연구 가운데 사례 연구라는 연구 방법을 사용하였고, 유상언의 연필 잡는 법이라는 단일 사례를 대상으로 그와의 인터뷰 자료와 그가 주장하는 내용과 관련한 한글 파일, 유튜브 자료, 학생들의 글씨 자료, 소감문이나 편지글 등과 함께 교과서와 교사용지도서를 다층적으로 분석하였다. 결과 그 결과 현행 2015 개정 교육과정 1학년 교과서에서 안내하고 있는 손가락의 위치에 문제가 있다는 것을 발견하였다. 즉, 글씨를 쓸 때 손가락의 위치를 보면, 엄지와 검지를 둥그렇게 모으면서 연필을 잡는 방법은 최적의 방법이 아니라는 것이다. 그리고 글씨를 쓸 때 팔꿈치를 책상 위에 올리도록 한 것도 적절하지 못해서 수정해야 할 지침이다. 이와 달리 유상언이 제안하는 연필을 바르게 잡는 방법은 학생들이 글씨를 바르게 쓰는 데 도움을 주는 더 나은 방법이다. 그가 제안하는 연필을 바르게 잡는 방법은 다음과 같다. 첫째, 엄지손가락과 가운뎃손가락 끝을 맞잡아 둥글게 만든 후 가운뎃손가락의 손톱 부위와 집게손가락이 시작되는 뼈 옆 부위에 연필을 올린다. 둘째, 엄지손가락을 위로 들어서 직각으로 꺾은 후 연필을 위에서 지그시 눌러 준다. 셋째, 집게손가락도 직각 가깝게 꺾어서 엄지와 가운뎃손가락의 사이에 힘주지 않고 살짝 붙여만 준다. 넷째, 글씨 쓰는 손목이나 팔이 책상 모서리에 약간 걸치는 정도로 해서 글씨를 쓴다. 결론 유상언이 제안하는 연필 잡는 손가락의 모양과 위치에 따라 글씨를 쓰면, 연필에 가해지는 손가락의 힘이 균등하게 유지되어 편안한 자세로 글씨를 더 바르고 쉽게 쓸 수 있다.

In this study, an effective methodology to introduce knowledge management system into the retail business is suggested by overall analysis of examples those were carried out in business area. Different from existing studies, which focus on theoretical aspect only, this study focuses its attention on theoretical & practical aspect simultaneously and tries to find a long-term & integrated knowledge management strategy. With examining the examples of knowledge management, this study deals with the fundamental conception, the procedure and the organization of knowledge management. Moreover, this study practically analyzes the knowledge management system of the company named "H", one of the retail business companies. By clarifying the problems, which is involved in the knowledge management process of the above company, this study suggests an improvement methodology to introduce and settle down knowledge management system into retail business company for the future. This study has good results in the viewpoint that it gives a definite direction of knowledge management introduction. However, there is some limitation such as the insufficiency of examples and the omission of documented analysis. Therefore, this study leaves some task to be achieved in the future.

스포츠미디어의 유통 콘텐츠 결정요인으로서 스포츠 스타: 의제설정 이론의 암묵적 전제를 중심으로

Sang-Keon YOO,김용은,서원재 한국유통과학회 2019 유통과학연구 Vol.17 No.10

Purpose - Media is a significant distributional channel in sport. In terms of determining the influencer in building sport media contents, recent sport media studies have employed agenda-setting theory, assuming media itself as the agenda provider. In a real-world situation, however, sports stars have been deemed key factor determining distribution contents in sport. The starting point of this study is the “tacit premise” of agenda-setting theory. Given the agenda-setting theory, the current study attempted to explore the function of sport stars as an agenda provider, which is a key determinant of sport distribution. Research design, data, and methodology – This study has reviewed articles of Yuna Kim, Sang-hwa Lee, and Hyun-jin Ryu from daily newspapers including as dong-a ilbo and joongang ilbo (2013 to 2017). The study collected data, portable document format (PDF), from the online archive of dong-a ilbo and joongang ilbo. We coded the length of the article, the frequency, the size of the picture, and the structural form of the article. Inter-coder reliability was compared with data previously investigated by the researcher. Inter-coder reliabilities for study 1 and 2 was .89 and .85. To examine hypotheses, descriptive analysis, correlations, and cross-tap analysis were performed. Results – The results partially supported the hypotheses proposing the significant role of sports stars as the agenda setters in distributing sport media contents. In specific, the study found that the number of articles about sports stars prevailed the number of articles about regular athletes. Besides, studies found that the use of photos was more frequent in articles of sports starts than that of regular athletes. In sports newspaper articles, featured story articles were used more than straight-articles for news relating to sports stars. Also, sports newspaper of sports stars contained more information associated within an event rather than outside of an event. Conclusions – In sports journalism, this study challenges the current theory that the media affects the composition and the content of sports coverages. As the principle of the agenda-setting of sports media, the influence of sports stars must be continuously studied along with a follow-up study.

Development as education for social justice

Sung‑Sang Yoo,Ridwanul Mosrur,Eunhye Lee,Diego Toca Andrea 서울대학교 교육연구소 2019 Asia Pacific Education Review Vol.20 No.2

The correlation between education and development, with time, went through many changes along with the changes of perspectives. Since both of these concepts encompass wide ranges of social phenomena and factors, the analysis remains always complicated. However, in the era of SDGs and at the time when post-development debates have been raised, it is important to address this conceptual correlation through the conceptual analysis. Diferent development theories, as refected in the discussion, have presented the vitality of education in development process from diferent angle, in deeper analysis it became clearer that actually two major trends exist—education ‘for’ development and education ‘in’ development—under which all can be grouped. However, the critics of those diferent development theories paint the picture with an assumption that the role of education in the process of development has been misunderstood and mis-presented to some extent. This poses the debate towards fnding how the role of education to development process can be better realized and, therefore, this paper analysed it from three key thoughts towards redefning the paradigm. Goulet argues that development needs authentic in ethical way where Sen more freedom should be given by widening individual’s capability. However, in close analysis on Freirean thoughts, the limits of this relation remain un-encompassed as the defnition of development is rather contextual and fexible for the discourses on the role of education for social justice.

신경향파시의 재인식

유성호 ( Sung Ho Yoo ) 한민족문화학회 2014 한민족문화연구 Vol.45 No.-

신경향파의 등장 맥락을 바라보는 시각은 그동안 두 갈래의 평가를 낳아왔다. 하나는 순조로운 근대시의 발전을 가로막은 ``생채기``에 불과했다는 부정적 시각이고, 다른 하나는 보다 적극적인 의미를 부여하여 프로문학의 발전도상에서 빚어진 이행기적인 의미로 한정하는 시각이다. 후자는 프로시로 나아가는 전 단계의 자연발생적인 성취를 신경향파시로 범주화한 결과이다. 우리는 이러한 두 가지 견해를 넘어서는 차원에서, 신경향파시가 한국 시의 다양성과 공적 심층성을 중요하게 발전시켰고, 나아가 프로문학의 전 단계로서의 이행기적 속성이 아니라 독자적 미학으로도 매우 중요한 속성을 견지하고 있다고 파악할 수 있다. 그 핵심적인 내적 원리는 다름아닌 민족주의와 낭만성을 ``비극성``이라는 미적 범주로 통합, 결속하였고, 민족 현실의 전체성을 사유한 것 등에서 찾을 수 있다. 신경향파시의 초기 단계는 사회적 약자에 대한 소박한 긍정과 신뢰를 담는 데 멈추었다면, 그러한 한계는 이상화, 박팔양에 의해 극복된다. 이들에 의해 약자에 대한 옹호 지향은 민족주의적 열정과 매개되기도 하고 이산離散이라는 민족적 경험과 깊이 결부되기도 한다. 이렇게 신경향파시는 한국 근대시의 계몽적 출발의 초점을 개인으로 돌리지 아니하고 민족 혹은 집단의 경험으로 돌림으로써 새로운 계몽을 추구하였다. 하지만 신경향파시는 카프로 순조롭게 인적 연속성을 이월하지 못하였다. 그것은 그들 자신의 내적 기질에서 연유하는 것이기도 하고, 외적 기율이나 경험의 차이에서 발생하는 것이기도 하다. 신경향파시가 주목했던 ``민족`` 패러다임은 매우 경험적인 것이었던 데 비해, 프로시가 받아들였던 마르크시즘은 너무도 추상적인 것이었기 때문이었을 것이다. 그리고 신경향파시가 주목했던 ``검``이나 ``신`` 같은 종교적 개념이 소멸하고 일방적으로 과학성으로 경사하게 된 것도 카프로의 이월이 신경향파시의 어떤 가능성을 지워버린 실례로 평가될 만하다. 따라서 우리는 신경향파시가 카프로 이월되어간 진화의 양상과 함께, 카프로 이월하면서 소진된 가능성과 자산을 함께 탐색해볼 수 있을 것이다. A perspective on the appearance of the Anti-Conventional School has produced two different assessments until now. A negative viewpoint is that it was merely a ``wound`` that stoped the smooth development of modern poetry. The other actively attaches meaning to it and sees it as a transitional group organized during the developing process of proletarian literature. The latter is the result of categorizing the spontaneous achievements gained prior to proletarian poetry as the Anti-Conventional School poetry. From the dimension of overcoming these two views, this paper proved that the Anti-Conventional School poetry considerably fostered the diversity and public depth of Korean poetry and further it preserved not transitional properties as a preceding phase of proletarian literature but important features as an independent aesthetics. The central inner principle could be found from none other than the fact that it integrated and united nationalism and romantic ideas into the aesthetic category of ``tragedy`` and thought about the totality of national reality. The Anti-Conventional School poetry ended of expressing naive affirmation and trust in the week of society in the early period, however, its limitations were overcame by Lee, Sang-hwa and Park, P`al-yang. With them, the tendency of supporting the week was bridged to the passion for nationalism or deeply associated with national experience of diaspora. In this way, the Anti-Conventional School poetry pursued a new enlightenment by not turning the focus of enlightening departure of modern Korean poetry to individual but to the experience of a race or group. The Anti-Conventional School poetry, however, could not successfully hand over its features to KAPF. This was coming from their cast of mind and from the difference in external discipline or experience. Also, it was because that the paradigm of ``a race`` the Anti-Conventional School poetry paid attention to was extremely empirical, but Marxism accepted by proletarian poetry was too abstract relatively. And the extinction of the religious concepts such as ``geom``(검, god) or ``shin``(신, god) that received attention of the Anti-Conventional School poetry and the inclination toward science could be considered as examples of removing the possibility of the Anti-Conventional School poetry with the transition to KAPF. Therefore, the exhausted possibility and assets of the Anti-Conventional School poetry could be searched with the aspects of evolution during the transition to KAPF.

晩唐 皮日休詩와 黃巢亂과의 相關性

유성준(Yoo Sung-joon) 우리문학회 2004 우리文學硏究 Vol.0 No.17

Pi Ri Xiu(834~883) is known for his poetry, which portrayed the social injustices of his era, for his advocacy of Mencius(孟子) and Han Yu(韓愈), and for his literary association with an insular Soochow(蘇州) coterie centered about Lu Gueimeng(陸龜蒙). Provincial life kept him in close touch with the people and much of his early verse reflects their concerns and hardships:<br/> Deep into autumn the acorns ripen,<br/> Scattering as they fall into the hillside scrub.<br/> Hunched over, a hoary-haired crone<br/> Gathers them, treading the morning frost.<br/> (From “Hsiang-wen tan” [ Lament of an Old Acorn-gatherer])<br/> Having been in the capital off and on since 864, Pi passed the chin-shih(進士) examination in 867. He seems to have never been comfortable in the capital city, which was indeed not the mecca for young graduates it had been several generations earlier. Unable to find either patron or position-the two wend hand in hand in the late Tang-he went to Soochow and attached himself to the coterie of the prefect, Ts’ui P’u. in a matter of months he and Lu Kueimeng, a scion of a prominent local clan, had become fast friends. Pi traveled back to the capital and served in the government there, attaining the rank of Erudite of the National University. His family may have stayed in the South. And as he returned there in 880 with an appointment to a post in Chang chou he encountered Huang Chao and his rebel horded returning from Canton. Apparently swept up by the possibility of replacing a corrupt regime, Pi joined the rebels and upon their arrival in Chang-an was made a Han-lin(翰林) Academician in the Ta-Ch’i dynasty. It soon became apparent that Huang Chao was not receptive to advice from his courtiers; many of them were persecuted for admonishing him. Although there are several accounts of Pi’s death(this is the other major concern of modern critics, but none of the theories has solid textual support), it seems most likely that Pi offended Huang Chao and was put to death by the rebel leader.<br/> Pi Ri Xiu’s poetic legacy represents the two major tendencies of the late Tang and perhaps illustrates by its inadequacies some of the reasons for the prominent place of the new lyrics(tz’u 詞) on the literary stage of the Five Dynasties and Sung. The inner drive which seems to have steered Pi through his capricious career-from avid reformer, to recluse-poet, to rebel-in addition to the large and varied corpus he has left, make him one of the most fascinating minor literary figures of the late Tang.

유건성(Geon Sung Yoo),변재훈(Jae Hoon Byeon) 한국체육교육학회 2009 한국체육교육학회지 Vol.14 No.1

The purpose of this study was self-identity of individuals with physical disabilities participating in physical activity. Subjects included 198(male: 143 female: 58) with individuals with physical disabilities. The questionnaire that was developed by Park Ah-Chung(1996) was used self-identity scale of Korean. It was revised by Lee Sung-Guk(1999) which consisted of 6 factors, 48 items. Construct validity of the instrument was checked by Factor analysis. Reliability of questions was confirmed by Cronbach`s α value(.783). The data analysis were Independent t-test, one-way ANOVA, and multiple regression analysis. The results were as follows; First, job and incomes had significant effects on self-identity of individuals with physical disabilities. Second, physical instructors, mass media, and friends had significant effects on self-identity of individuals with physical disabilities. Third, physical activity period, group exercise, and athletes with disabilities had significant effects on self-identity of individuals with physical disabilities. Fourth, high understanding of disability traits significant difference than low understanding of disabilities traits on self-identity of individuals with physical disabilities. These results implied that individuals with physical disabilities participation in physical activity had significant effects on their self-identity according to socio-demographic variables, significant other, type of physical activity, participation type of physical activity, and understanding of disability traits.
