The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

This study was focused on improvement of milk production in Mongolia dairy industry by artificial insemination (AI) technology, of which was supported from ODA project of KOICA in Republic of Korea. The study was started from January 2009 to present and 3rd years in this year. So, all data, especially synchronization and pregnancy of dairy cows (Holstein) will be summarized in final result in this year. For synchronization, total 81 dairy cows selected from 4 private farms that were 38, 30, 8 and 5 in Undarmal milk, Onjin (Enkhbayer), Jargalant, and BRM School, respectively. All the dairy cows were injected intramuscular (IM) of 5 ml PGF2α in the vulva and detected estrus 2 to 3 days after PGF2α injection. Total 78 out of 81 dairy cows (96.3%) were detected estrus by only 1 time injection of PGF2α. The dairy cows that were induced estrus, inseminated with 0.5 ml dairy frozen semen by conventional AI techniques. The pregnancy diagnosis of the AI dairy cows was detected by uterus palpation after 60 days of insemination. Total 75 from 78 inseminated dairy cows (90.1%) were diagnosis pregnant. The estrus induction and pregnant rate were very effective using PGF2α injection and conventional AI techniques in Mongolia dairy cow. The results indicated that AI after estrus induction in Mongolia dairy cows could be applied to dairy breeding technology to improve the breeding efficiency and milk production.

미국 헤게모니하 한국문화 재편의 젠더 정치학 : 1940~1950년대 정비석 대중소설을 중심으로

정종현 동국대학교 한국문학연구소 2008 한국문학연구 Vol.0 No.35

이 글에서는 식민지 말기부터 1950년대 중반까지의 정비석 소설을 각 시대적 맥락 위에서 읽음으로써 파편적, 일면적으로 고찰되어온 정비석 문학의 문제성을 전면화하고자 했다. 특히 한국전쟁 이후 미국 헤게모니하 한국문화 재편의 과정에서 창작된 『자유부인』, 『민주어족』 등의 대중문학이 『사상계』 지식인 담론에 소설적 육체를 부여함으로써, 지배계급과 지식인 엘리트 집단 사이의 정치적 분열을 구조화하고 있다는 사실을 분석했다. 또한 왜곡된 근대화를 ‘자유부인’이라는 여성젠더를 통해 표상하면서, 올바른 근대화의 중심으로 소환하는 ‘부덕’, ‘인종’ 등의 전통 윤리가 식민지 말기 파시즘 윤리를 구성했던 세목들을 재구조화한 것임을 규명하였다. 결론적으로 정비석 문학을 사례로 식민지 말기, 해방기, 1950년대의 한국문학을 연속/비연속의 ‘겹눈’의 관점을 통해 접근하는 새로운 방법론의 필요성을 제시했다. The purpose of this study is to newly examine and reveal the problematic facets of Jung Bee-suk's works that have been analysed too fragmentary or one-sidedly. For this I will read his novels in the connection with each period's contexts from the late colonial period to the middle of 1950s. Especially his popular literature including Jayu-buin and Minju-ohjok, which were written during the process that Korean culture was being reorganized under American hegemony, injected bodies' discourses into the intellectual discourses of the journal Sa-sang-gye. As a result, it can exemplify the fact that his novels played a role to structuralize the political rupture between the ruling classes and the elite groups. In addition, I'd like to point out that by representing the distorted modernization through a female gender, ‘Jayu-buin’, the traditional morals such as ‘buduk (womanly virtues)’ and 'injong(self-surrender)' were the restructuralized ones from the items of fascist ethics of the late colonial period. Finally, I present the argument that there should be new approaches on the Korean literature of the late colonial period, the liberation period and 1950s through this case study of Jung Bee-suk's works. And the new approaches should be based on the points of view of both continuous and discontinuous ‘compound eye’.

원위 대퇴골의 고립성 골연골종에서 발생한 속발성 연골 육종 1례 보고

정필현,황장수,강석,김용민,오형호,채동주,김종필 동국대학교 경주대학 1996 東國論集 Vol.15 No.-

연골육종은 비교적 서서히 자라며 늦게 전이하는 악성 연골 종양으로 알려져 있다. 골 연골종에서 발생한 속발성 연골육종은 발생빈도는 드물며 타부위로의 전이가 적고 악성도가 낮은 경우가 많아 적합한 수술적 치료로서 좋은 예후를 보이는 것으로 보고되고 있다. 본 동국대학교 정형외과학 교실에서는 우측 대퇴골 원위부 골간단부에 생긴 고립성 골 연골종에서 이차적으로 발생한 연골육종을 치험한 바 문헌고찰과 함께 보고하는 바이다. A case of Secondary Chondrosarcoma Arising from Solitary Osteochondroma of the Distal Femur Department of Orthopaedic Surgery, College of Medicine, DongGuk University Phil Hyun Chung M.D., Jung Su Hwang M.D., Suk Kang M.D., Yang Mln Kim M.D., Hyung Ho Oh M.D., Dong Ju Chae M.D., Jong Pil Kim M.D. Chondrpsarcoma is a malignant cartilage-forming tumor that grows slowly and metastasis of this tumor occurs in late stage. Secondary chondrosarcomas arising from a solitary osteocartilaginous exostosis are rare and those have a better prognosis than other chondrosarcomas, and they rarely metastasize. We present our experience with a case of secondary chondrpsarcoma arising in solitary osteochondroma of distal metaphysis of right femur with clinical details.

3,1운동 표상의 문화정치학: 해방기~대한민국 건국기의 3,1운동 표상을 중심으로

정종현 ( Jong Hyun Jung ) 한민족문화학회 2007 한민족문화연구 Vol.23 No.-

근대 한국민족의 탄생에 결정적인 영향을 준 사건인 3·1운동은 해방기 새로운 민족국가(nation) 형성에 대한 각 정파의 구상에 따라 다르게 담론화되었고, 그 표상 또한 상이하였다. 우파는 3·1운동을 민족저항사의 정점으로 하는 우파적 민족주의 내러티브를 주조하였다. 박종화의 민족 , 청춘승리 등은 그 좋은 사례인데, 이 소설들을 통해서 동학, 독립협회, 3·1운동, 광주학생운동으로 이어지는 민족저항사가 서사화된다. 이 과정에서 이승만을 중심으로 하는 단독정부 수립이라는 우파 민족주의 이데올로기가 정당화되고 있다. 한편 좌파는 안회남의 「농민의 비애」, 「폭풍의 역사」등의 소설을 통해서 확인할 수 있듯이, 3·1운동 의 주도세력을 농민, 노동자 등의 계급적 주체로 규정하며 `민족`이라는 동일자를 계급적 범주에 기반하여 재편하고 있다. 이는 이후 북한의 3·1운동 표상으로 이어진다. 1948년 대한민국이 건국되면서 단독정부 수립파가 만들었던 3·1운동 표상이 확대 재생산되면서 통일적인 표상체계를 갖추어 나가게 된다. 3·1정신은 계급과 성별을 떠난 민족 전체의 총의를 모았던 탈이념적 민족공동체의 정신으로 소환된다. 또한, 이전의 이데올로기적 균열을 봉합하는 기호로서 `유관순`이라는 `聖`처녀가 이 표상체계의 중심으로 대두한다. The March 1st Movement has been regarded as the largest national resistance movement during Japanese Imperialism which made a profound impact on the birth of modern Korean nationalism. In the era of liberation, a range of political factions made this movement into different discourses in which the representations also varied accordingly. That is, the two kinds of representations and narratives that came from the right wing groups and the left wing groups differed and further more competed against each other in the process of conceiving and constructing `we(nation-state)`. Rightists coined the narratives of rightist nationalism in which the March 1st Movement was represented as a peak point in the history of national resistance. Such narratives include novels like Park Jong-Hwa`s Min-Jok and Chung-Chun-Seung-Ri where a stream of Donghak, Dongniphyeophwoi, the March 1st movement and Gwangju haksang undong became a consistent narrative containing a whole history of national resistance movement. Especially it is notable that the rightist nationalism ideology was being justified in these narratives, by supporting the establishment of a separate government in South Korea by Lee Seung-Man. In contrast, the leftists tried to reorganize the term, `nation` based on the class category by identifying the leading forces of the March 1st Movement as the class subjects including farmers and working class. Their view points led to the representations of the movement in North Korea. Novels like Ahn Hee-Nam`s Sorrow of Farmers and History of Storms embodied such perspective. From 1948 when Daehanminguk was established, the representations that rightists, especially the group supporting a separate government, had composed, gradually developed into a steady and whole representational system. The spirit of the March 1st Movement in the first Constitution was summoned as the essence of a national community which was beyond any ideologies and stood for the whole nation regardless of classes and genders. In addition, Yu Gwan Soon, a saint virgin, emerged as a sign seaming former ideological fissures. In this regards, it is thought that the representations of the March 1st Movement can be key codes which make us decode the complicated contexts in which both Koreas constructed their separate societies depending on their own historical backgrounds.

사각블록을 갖는 채널내의 유체운동에 관한 수치해석적 연구

정경진,김광추,이종원,김종현 慶熙大學校 레이저 工學硏究所 1994 레이저공학 Vol.5 No.-

A numerical study of fluid flow in the channel with rectangular blocks is performed by using finite volume method. SIMPLER algorithm and Power-law scheme are used for numerical scheme. Numerical computation is divided into the precomputation and the main computation. In the precomputation, driven square cavity and backward-facing step are studied, and the results are shown to agree with other numerical and experimental data. In the main computation, convergence become more slow as the Reynolds number is increased. For flow fields near blocks, the severe pressure gradient is formed near the upper-left corner, and recircular zones are formed in the front and rear of blocks and in the space of blocks. In addition, the size of the recircular zone become larger as the Reynolds number increases.

생체용 Ti₁-x-Zrx합금의 기계적 성질과 내부식성

정종현,백승남,노학,고영무 대한치과기재학회 1998 대한치과재료학회지 Vol.25 No.1

While titanium and its alloys has been well studied for a long time, new interest in these materials and their properties has arisen in recent years with respect to their application as biomedical metallic materials. For practical purposes, the following performances are essential for biomaterials. (1) low specific gravity (2) high corrosion resistance (3) good biostability and biocompatibility (4) sufficient mechanical properties (5) non-toxicity To develop biomedical implant materials having all the properties mentioned above, new titanium-zirconium alloys were prepared in this study. Mechanical properties and corrosion resistance were then investigated for as-cast and as-homogeneized Ti₁_x-Zrx alloys in order to reveal their possible use for biomaterials. From the experiments, the following results are obtained: 1. No martensite structure are observed in the specimens made of pure Ti and Zr. In contrast them, Ti-Zr alloys containing 18wt%Zr, 24wt%Zr and 48wt%Zr show a kind of martensite structure regardless heat treatment. 2. Fineness of structures for as-cast-alloys seems to vary with alloy composition. Ti-Zr alloy containing 48wt%Zr shows the finest microstructure. 3. Hardness of Ti-Zr alloys shows continuous change through the system and the alloys containing 48 to 60wt%Zr indicate higher hardness compared with those of pure Ti and other alloys. It is well known that hardness is usually changed with substitutional atoms, and effect of solute atom on hardness is greatest with an equi-atomic composition. The greatest hardness which was obtained in Ti-Zr alloys containing 48 to 60wt%Zr is therefore reasonable. Also, enhanced hardness can be explained on elastic interaction between dislocation and substitutional solute atoms in crystal structure and on fineness of structure. 4. Pure Ti and Zr alloys containing 6wt%Zr, 12wt%Zr, 18wt%Zr, 36wt%Zr show better corrosion resistance compared with those of pure Zr, stainless steel(SUS 316L) and the Ti-Zr alloy containing 48wt%Zr. 5. Comparing hardness, microstructure and corrosion of Ti₁_x-Zrx alloys, no large differences between as-cast and as-homogenized alloys are seen.

The results of this study indicate that the finishing operation should be carried out in a logical, all scratches are removed, after which a polishing material is applied to give a high luster to the finished work.

유관순 표상의 창출과 전승 : 해방 이후 제작된 유관순 영화의 내러티브를 중심으로

정종현 동국대학교 한국문학연구소 2009 한국문학연구 Vol.0 No.36

Gwan-sun Yu was a woman titled Korean national hero as icon of the Samil Independence Movement(on Mar. 1, 1919) and as representative of sufferings and resistances in colonial era. Historically, the emblem of Gwan-sun Yu which symbolizes national sacrifice and resistance was formed primarily by Korean nationalist group, independent government faction and Ewha School alumni after the 1945 Liberation of Korea. A heroic life story on Gwan-sun Yu (authored by Yeong-taek Jeon, 1948; against a background of Gwan-sun Yu Memorial Foundation and Korea Bibliography Publishing Committee) and a film titled ‘Gwan-sun Yu’(directed by Bong-chun Yun, 1948) based on her life story become original texts for framework and popularization of Gwan-sun Yu's emblem that has been handed down to this generation of Korean society. In the Year 1948 texts of Jeon and Yun, the sacrifice of a bold Korean girl student from a mission school called Ewha School became construed in a sense of nationalist and Christian martyrdom, and took a position of ethical authority for national legitimacy. This way, her political symbolism complied with cultural state planning where ruling elites who dominated the establishment of independent regime for South Korea aimed to give Korean national essence to southern state. Yun's 2nd film release titled ‘Gwan-sun Yu’(released in 1959) formed a narrative on Gwan-sun Yu in association with historical memory on areas below the 38th Parallel(including Gyeongju). Here, a political mechanism of location works to identify ‘South Korean’ nation as homogeneous persons. Gwan-sun Yu's emblem after the April Revolution(Apr. 19, 1960) becomes a critical case that demonstrates conflicts and rivalry between state (government) and civil society. Yun's 3rd film release titled ‘Gwan-sun Yu’(1966) suggests an evolution of previous Gwan-sun Yu's emblem, which is a combination of civil self-images(pursuing universal values like freedom and philanthropy after the April Revolution) and enhanced nationalism(after the Korea-Japan Ministerial Meeting). Even in this period, Korean government was still committed to spotlighting Gwan-sun Yu as heroic figure to make propaganda for Korean nationalism and government-led racialism under the influence of the Cold War. In particular, Director Gi-deok Kim's ‘Gwan-sun Yu’(1974), a film produced under the rule of Revitalizing Reforms (Yusin) system and Emergency Measures, forms an emblem of Gwan-sun Yu which projects Yusin ideology in a combination of nationalism and patriarchal authority. In this film, Gwan-sun Yu is presented as a role model that internalizes the rules of ‘the Hwarang School’ established to educate contemporary teenagers in the ideology of Yusin, rather than as a heroine who resisted national injustice. 유관순은 1919년 3.1의 아이콘이자 식민지의 수난과 저항을 대표하는 여성 영웅이다. 민족의 희생과 저항의 상징인 유관순 표상은 해방 이후 민족주의 계열, 단독정부 수립파, 이화학원 동문들의 주도로 구성된 것이다. 유관순 기념사업회와 전기간행위원회를 배경으로 하는 1948년의 전영택의 전기, 이를 바탕으로 제작된 윤봉춘의 영화 「유관순」(1948)은 이후 한국 사회에서 전승되는 유관순 표상의 골격을 결정하고 대중화한 기원의 텍스트들이다. 전영택과 윤봉춘의 1948년 텍스트를 통해 기독교 미션 이화학당 출신 소녀의 희생은 민족주의적, 기독교적 순교로 의미화되었으며, 민족적 정통성의 도덕적 권위로 자리잡았다. 이러한 유관순의 정치적 상징성은 남한 단독정권 수립을 주도한 통치엘리트들이 남한 국가에 민족적 정수를 부여하고자 한 문화적 국가 기획에 부합하는 것이었다. 1959년 개봉된 윤봉춘의 두 번째 「유관순」 영화에서는 경주 등 38선 이남의 역사적 장소와 결부된 유관순 내러티브를 구성함으로써 ‘남한’ 민족을 균질화된 동일자로 구성하는 장소의 정치학이 작동하고 있다. 4ㆍ19 이후의 유관순 표상은 국가(정부)와 시민사회가 갈등하고 길항하는 양상을 보여주는 중요한 사례이다. 1966년 윤봉춘의 세 번째 「유관순」의 시나리오에는 4ㆍ19 이후 자유, 박애 등의 보편적 가치를 추구하는 시민적 자아상과 한일회담 이후 고양된 내셔널리즘의 열망이 결합된 유관순 표상이 제시되고 있다. 이 시기에도 국가(정부)는 여전히 유관순을 국가주의와 냉전 하의 관주도 민족주의를 선전하는 영웅상으로 제시하였다. 특히 유신헌법과 긴급조치 하에서 제작된 1974년 김기덕 감독 제작의 「유관순」에는 국가주의와 가부장의 권위가 결합된 유신 이데올로기가 투사된 유관순 표상이 구성되고 있다. 이 영화의 유관순은 불의에 저항한 영웅이라기 보다는 당대 청소년에게 유신 이념을 교육시키기 위해 설립했던 ‘화랑교육대’의 규율을 내면화한 역할 모델로 제시되고 있다.
