『사랑의 헛수고』의 대론 구조

박우수(Woo-Soo Park) 한국셰익스피어학회 2011 셰익스피어 비평 Vol.47 No.3

The Debate in Love's Labour Lost Abstract Woo-Soo Park The debate between spring and winter in Shakespeare's early ‘lyrical’ comedy, Love's Labour Lost, is a unifying theme and structure; it is not attached for the musicians at the time of rehearsal of the play, written on a separate paper. The dialogue or debate of spring and winter reflects the traditional medieval literary form representing two irreconcilable opposing values or attitudes of life, as shown in such works as The Owl and the Nightingale(c.1250) and The Debate and Stryfe Between Somer and Wynter(c.1530). The Shakespearean debate, which was originally planned as the end of the pageant play, “the Nine Worthies”, is replaced as an epilogue to the main play. Through this technical replacement in the play of the dialogue between spring and winter, Shakespeare critiques the artificiality of the traditional debate form as a kind of aristocratic and intellectual game or war of wits. As a language game, the debate form seems to Shakespeare's eyes unnatural in separating the intermingled yarns of life; rather his vision of life is comprehensive and dialectical. The vigorous and energetic sexuality of the spring time is also found in the ice-cold winter when the owl hoots to the greasy Joan to make it. As in the cuckoo's song of love is overheard the undertone of infidelity and betrayal, the two opposite seasons of spring and winter are mutable in the cyclic space of life. By his critical and ironical appropriation of the inherited debate form, Shakespeare is satirical of the humorous young aristocrats in their speech and behavior. If the anti-comic ending of the play is in itself the Shakespearean experiment on the comic genre of courtship and marriage, the debate form in the play works as his ‘living art.’ However, this re-appropriation of the literary form in Shakespeare does not mean the final triumph of Apollonian song over the Mercurian eloquence and letters. The songs are written. The Shakespearean authority in the theatre as a playwright lies somewhere between the borderland of speech as a breath and textual letters. The theatrical representation is both a voice and a letter at once.

본 연구는 유아의 사회적 능력 수준에 따른 창의성의 변화를 비교하기 위하여 T광역시 소재 유치원의 만 4세 유아 147명을 대상으로, 우수경(2002)의 유아 사회적 능력 검사와 전경원(2001)의 유아 도형 창의성 검사를 실시하였다. 연구 결과, 첫 째, 사회적 능력이 높은 유아들이 낮은 유아들보다 창의성이 높은 것으로 나타났다. 그리고 사회적 능력과 창의성 측정 시기 간에 상호작용 효과가 있는 것으로 나타나, 사회적 능력이 높은 유아들의 창의성은 측정 시기마다 점점 증가한 반면, 사회적 능 력이 낮은 유아들은 창의성이 증가했다가 다시 감소하였다. 둘째, 창의성 하위요인별 로 볼 때, 유창성, 독창성, 개방성은 사회적 능력에 따라 차이가 있으나, 민감성은 차 이가 없었다. 그리고 창의성 하위요인 중 독창성은 사회적 능력과 독창성의 측정 시 기 간에 상호작용 효과가 있는 것으로 나타나, 사회적 능력이 높은 유아들의 독창성 은 측정 시기마다 점점 증가한 반면, 사회적 능력이 낮은 유아들은 독창성이 증가했 다가 다시 감소하였다. This study investigates the relationships change process between young children``s creativity and social competence. Participants consist of 147 kindergarten children in T-city. The instruments are Woo``s(2002) Children``s Social Competence Scale and Chon``s(2001) the Korean Figural Creativity Test for Young Children. The main findings of this study are as follows. First, a child’s creativity differs according to the child’s level of social competence. Children displaying high social competence demonstrate, as time goes by, increased creativity. Second, a child’s fluency, originality, and openness differ according to the child’s level of social competence, though no difference is observed regarding sensitivity. An interaction effect is found in originality and social competence such that a high level of social competence is associated, as time goes by, with an increase in originality.

According to the system of the oriental traditional science, everything has to be harmony and interact with one another. The fundamental notions of the traditional natural philosophy are "do(doctrine)", "taegeuk(the great absolute)", "yin-yang," "five primary substance", "four events", and "eight signs for divination". Taegeuk, especially, explains the formation and the death of all things in the universe through circulation of yin-yang, and shows the balance of nature and universe. Yin-yang, relative ideas produces four events, and four events also is divided into the eight signs for divination. 'four events', 'eight signs for divination' like 'yin-yang' indicates the cycle of nature. The essential notions of the traditional science are not different from those of modern chemistry. Taegeuk which is the origin of all things in the universe means the situation of harmony and balance through ceaseless circulation and connotes dynamic equilibrium on neutralization that chemical reaction get to. A number of opponent concepts such as acid-base, oxidation-reduction, atomic nucleus-electron are given an explanation by ying-yang(the positive and negative) that reaches Taegeuk through chemical bonding or reaction over simple antagonistic relationship. 'Yin-yang', 'four-events', 'eight signs for divination' do not imply a substance or a phenomenon in itself but the properties of them. That is why it is possible to see into various chemical concepts like a relative strength of acid-base, groups of periodic table with traditional scientific philosophy. We have regretfully neglected studies in traditional science. It is time to perform the concrete work connecting theory of traditional science with that of modern science for advisable appreciating of traditional science. Moreover, It is necessary to do research and development of educational programs or teaching-learning materials using the traditional science properly. 동양 과학 철학이나 자연 철학은 태극,음양오행,사상팔괘를 이용해 우주 만물의 운동과 자연의 순환을 설명하는데 있어 그 학문적 우수성을 부인할 수 없으나 현대의 화학식이나 수식이 현상을 미시적 관점에서 구체적으로 설명할 수 있는 것과는 달리 전통 과학이론은 거시적 관점에서 그 전체적 흐름만을 나타낸다는 한계를 가지고 있다. 그럼에도 불구하고 태극,음양오행 그리고 사상팔괘론을 중심으로 한 전통 과학 이론은 현대인들에게 과학에 대한 새로운 시각을 제공함으로써 무분별하고 비윤리적인 과학 기술 활용으로 인한 전 지구적인 문제들을 해결하는데 있어 핵심적인 역할을 수행함은 물론 오늘날의 한국 과학이 한 걸음더 전진하는데 이바지 할 수 있을 것이다. 그러므로 서구 중심의 기존의 과학문명에만 머무를 것이 아니라 동양의 전통 과학 철학을 연구하여 민족의 과학 체계를 수립하고 과학의 토착화를 이루어야 한다. 이를 성공적으로 수행하기 위해서는 전통 과학과 현대 과학 사이에 다리를 놓는 구체적인 작업이 본격적으로 진행되어야 한다. 기본적인 화학 개념들을 전통 과학적 관점에서 재해석 하는 것은 물론이고 더 나아가 전통 과학의 이론을 이용하여 화학 반응 과정을 구체적으로 설명하려는 시도가 필요할 것이다.

The HBV DNA Amounts in Serum Have No relationship with ALT level and Hetergeneous Population Coexits in Chronic Hepatitis B Virus Infection. Proceedings of International Symposium on East-West Medicine, Seoul. 212-230, 1999. -Hepatitis B is caused by hepadnavirus. Hepatitis B virus replicates through 3.5kb pregenomic RNA intermediate which is regulated by core promoter. Pathogenesis of hepatitis B virus has been bilieved the result of host immune response. But recently many studies have reported that high level of viral replication caused by mutation in core promoter might result in severs hepatitis. But these studies were performed in vitro, not in vivo. So there is yet debate about which factor, viral of host factor, is more important in pathogenesis of hepatitis B virus. So we measured real viral replication level in 204 chronic hepatitis B patients by quantifying HBV DNA from sera by our novel PCR-based more sensitive method, and compared these results with ALT level measured from same sera, which indicates liver cell damage. Surprisingly there are no significant correlation between HBV DNA quantity and ALT level. Then we cloned core promoter region. In SSCP, we found that many viral mutants coexist in one patient. Base on SSCP result, we chose main viral core promoter type in each patients, which is thought to determine overall viral replication level in this patient. Main type of core promoter region of each 41 patients were directly sequenced. And with these we measured promoter activity by luciferase assay system and compared promoter activity with on another. We found tha there were some differences in promoter activity according to core promoter sequences. And we constructed replication-competent viral constructs with core promoter from 41 patients and Transfected these into HepG2 cell and measured HBV DNA by southern blot. There were also differences in HBV DNA quantity according to core promoter sequences. On these all results we investigated correlation between the effect of HBV core promoter on viral replication in vitro and HBN DNA quantity, ALT level from sera of each patients. We found there is no significant correlation among them. As a result, we concluded that in determining severity chronic hepatitis B patients, host factors of each patient is more important rather than replicative activity of virus itself.

Generally, headed reinforcement offers several advantages over straight bar or hooked bar anchorages to develop reinforcement in concrete members. The purpose of this study is to investigate the shear behaviors of reinforced concrete deep beam with headed reinforcement. Five deep beam specimens are designed to study the anchorage capacity of headed reinforcement as well as the contribution of H-bar and V-bar to the shear. Two anchorage types, standard 90-degree anchorage and headed reinforcement, are considered in design. From the tests, it is shown that In the test results, headed reinforcement is able to replace standard 90-degree anchorage as the anchorage method. The evaluation on the contribution of H-bar and V-bar in current design code for deep beam shows that the former is overestimated 75% and the latter is overestimated 17%.

당뇨병 환자에서 혈장 Thrombin-Antithrombin Ⅲ 및 Plasmin-α_2-Plasmin Inhibitor 복합체의 임상적 의의

김경욱,김은숙,정상수,윤수지,박우일,이준희,남수연,안철우,문병수,김경래,차봉수,송영득,임승길,이현철,허갑범 대한당뇨병학회 2002 Diabetes and Metabolism Journal Vol.25 No.5

연구배경:당뇨병 환자에서 혈액응고 및 섬유소용해 체계의 이상경향이 있어 그 결과로 여러 혈관합병증의 발생위험이 높다는 사실은 널리 알려져 있다. 그 기전은 아직 확실히 밝혀지지 않았으나, 고혈당으로 인한 혈장 단백질들의 비효소성 당화작용이나 산화성 스트레스로 인한 유리 라티칼 작용으로 응고항진이나 섬유소용해 활성의 저하를 유발하는 것으로 생각되고 있다. 최근 응고 및 용해인자와 그 억제자의 복합체들의 증가가 이 상태를 비교적 예민하게 반영한다고 알려져 있다. 방법:본 연구에서는 당뇨병 환자 101명과 정상 대조군 20명에서 혈장내 thrombin­antithrombin complex(TAT)와 plasmin­α₂­plasmin inhibitor complex(PIC)를 측정하여 비교하고, 당뇨병 환자에서 미세혈관 합병증과 대혈관합병증의 유무에 따른 차이와, 이미 혈관 질환의 위험인자로 알려져 있는 인자들간의 상관성을 알아보고자 하였다. 결과:1. 환자의 분포를 살펴보면 혈관합병증이 있는 군은 85명, 혈관합병증이 없는 군은 16명이었고, 평균연령은 각각 57.9±14.1세, 49.9±16.6세로 혈관 합병증이 있는 군에서 더 나이가 많았고, 체질량지수는 23.2±3.4㎏/㎡, 24.1±3.4㎏/㎡로 두 군간 유의한 차이는 없었다. 또 두 군간의 혈압 및 HbA1c, 공복혈당 및 인슐린과 C­peptide, 총 콜레스테롤, 중성지방, HDL­콜레스테롤, Lp⒜는 유의한 차이가 없었고, 미세혈관합병증이 있는 군에서 당뇨병의 유병기간이 길었다. 2. TAT 및 PIC의 농도는 정상 대조군에서는 2.8±1.2 ng/mL, 240.4±69.7 ng/mL이었고, 당뇨병 환자군에서는 9.5±22.6 ng/mL, 472.2±258.7 ng/mL이었다. TAT와 PIC 모두 당뇨병 환자군에서 정상 대조군에 비해 유의하게 증가되어 있었고(p<0.001), TAT/PIC ratio는 두 군간 차이가 없었다. 3. 당뇨병 환자의 혈관합병증에 따른 TAT 및 PIC, fibrinogen 농도는 합병증이 없는 군은 각각 4.1±2.4ng/mL, 362.2±272.0ng/mL, 322.7±102.4mg/mL으로 PIC와 fibrinogen의 증가를 보였으나, 연령을 보정한 후에는 통계학적 유의성은 없었다. 또 대혈관 합병증군에서는 각각 6.0±4.9 ng/mL, 507.4±321.6 ng/mL, 427.1±194.7 mg/dL이었으며 미세·대혈관 합병증군에서는 10.4±6.4 ng/mL, 484.8±269.7 ng/mL, 388.4±132.4 mg/dL으로 TAT의 증가를 보였으나 역시 연령을 보정한 후에는 통계학적 유의성은 없었다. 4. 미세혈관합병증군에서 HbA1c(>8%)가 높은 군의 PIC 농도가 유의하게 높았고(p=0.049), 대혈관합병증군에서 HbA1c(>8%)가 높은 군의 총 콜레스테롤 농도가 유의하게 높았다(p=0.042). 5. 총 당뇨병 환자군에서 PIC는 fibrinogen과 HbA1c와 양의 상관관계를, BMI와 음의 상관관계를 보였으며(r=0.47, 0.31,-0.25), 혈관 합병증이 없는 당뇨병 환자군에서만 TAT는 HbA1c와 양의 상관관계를 보였다(r=0.67). 결론:이상의 결과에서 혈장 TAT 및 PIC 농도는 당뇨병 환자에서 정상 대조군에 비해 의미있게 증가되어 있었고, 당뇨병 환자군에서는 연령의 증가와 유병기간이 혈액응고항진 및 용해의 장애에 큰 역할을 함을 알 수 있었으며, 총 당뇨병 환자군에 PIC와 HbA1c와 양의 상관관계를, BMI와 음의 상관관계를 보였으며 혈관 합병증이 없는 당뇨병 환자군에서만 TAT는 HbA1c와 양의 상관관계를 보였다. 따라서 당뇨병 환자에서 혈액응고 및 용해의 장애가 동반되어 있다고 볼 수 있으며, 혈장 TAT 및 PIC는 혈관합병증으로의 진행을 예측하는 지표로서 유용하리라 생각된다. 또 혈당조절정도와 상관성이 있으므로 혈당조절후에 추적검사를 시행하여 합병증의 예방이 가능한지 추후 연구가 필요하리라 생각된다. Background : Abnormality of coagulation and fibrinolystic system is known as a predisposing factor of vascular complication in diabetes. Although the pathogenesis is not well known, non-enzymatic glycation reaction and the increase in production of free radicals due to an increased oxidative stress may be linked to the hypercoagulibility and hypofibrinolytic activity. As indices of abnormality in coagulation and firinolysis in peripheral blood, plasma thrombin-antithrombin Ⅲ complex (TAT) and plasmin-α_2-plasmin inhibitor complex (PIC) were measured. The purpose of this study was to clarify whether hypercoagulability exists in diabetic patients with or without vascular complication. Methods : In our study, we measured plasma thrombin-antithrombin Ⅲ compelx (TAT) and plasmin-α_2-plasmin inhibit or complex (PIC) in 101 diabetic subjects and 20 controls. Comparing TAT and PIC levels in diabetic microvascular complication group, diabetic macrovascular complication group and controls, we examined correlation between risk factors associated with diabetic vascular complication. Results : 1. The group with diabetic vascular complication was older than group without complication. There was no significant difference in BMI, blood pressure, HbA_ic, blood sugar level, insulin, C-peptide, serum creatinine, total cholesterol, triglyceride, HDL-cholesterol, Lp (a) between two groups. The group with diabetic microvascular complication had longer duration of diabetes. 2. Concentration of TAT and PIC were 2.8±1.2 ng/ mL, 240.4±69.7 ng/ mL in controls and 9.5±22.6 ng/ mL, 472.2±258.7 ng/ mL in diabetic patients, respectively. TAT and PIC were significantly higher in diabetic patients than in control (p<0.001). But TAT/PIC ratio was no significant difference between two groups. 3. In diabetic patients, concentration of TAT and PIC and fibrinogen were respectively 4.1±2.4 ng/ mL, 362.2±272.0 ng/ mL, 322.7±102.4 mg/ dL in group without vascular complication and 5.3±4.1 ng/ mL, 529.5±258.7 ng/ mL, 374.9±106.2 mg/ dL in group with microvascular complication, which group had increase in PIC and Fibrinogen but no significance after correction of age. Concentration of TAT and PIC and Fibrinogen were 60.±4.9 ng/ mL, 507.4±321.6 ng/ mL, 427.1±194.7 mg/ dL in macrovascular complication, and 10.4±6.7 mg/ mL, 484.8±269.7 ng/ mL, 388.4±132.4 mg/ dL in combined vascular complication which group showed increase of TAT but also had no significant increase after correction of age. 4. In diabetic microvascular complication patients, group of high HbA_1c (>8%) (p=0.049) had significant high PIC concentration. In diabetic macrovascular complication patients, group of high HbA_1c (>8%) (p=0.042) had significant high total cholesterol concentration. 5. In all diabetic patients, PIC was positively correlated with fibrinogen and HbA_1c and negatively correlated BMI (r=0.47, 0.31, -0.25). Only in daibetic patients without angiopathy, TAT was positively correlated with HbA_1c (r=0.67). Conclusion : In this study, plasma TAT and PIC concentration significantly increased in diabetic patients compared with controls, and PIC was increased in group with microvascular complication, TAT were increased in group with combined micro macrovascular complication. However, there was no significance relationship existed when correctinf for age. PIC was correlated with HbA_1c. TAT was correlated with HbA_1c only in the group without angiopathy. Abnormality of coagulation and fibrinolysis were combined in diabetes, plasma TAT and PIC can be used as an index of vascular complication. Also we found the correlation with the degree of the blood glucose control. Therefore we need follow up study for the possibility of prevention of vascular complication after controlling the blood glucose to age-matched patients (J Kor Diaabetes Asso 25:354~363, 2001).

Dehydrocoupling of Bis(1-sila-3-butyl)benzene and 2-Phenyl-1,3-disilapropane to Polymers Using Zirconocene Combination Catalysts

Jun Lee, Jong-Hyun Kim, Soo-Yong Mo, Hee-Gweon Woo1, Do-Heyoung Kim, Jin Jun 조선대학교 기초과학연구원 2011 조선자연과학논문집 Vol.4 No.3

The catalytic dehydrocoupling of bis(1-sila-3-butyl)benzene 1 and 2-phenyl-1,3-disilapropane 2 by Cp2ZrCl2/Red-Al and Cp2ZrCl2/n-BuLi was reported to compare their catalytic efficiency. The dehydrocoupling of monomeric silanes 1 with the Cp2ZrC12/Red-Al and Cp2ZrCl2/n-BuLi combination catalysts produced two phases of polymers: one is a highly crosslinked insoluble solid, and the other is noncross-linked or slightly cross-linked soluble oil and could be a precursor for the solid polymer. The dehydrocoupling of 2 with the Cp2ZrCl2/n-BuLi combination catalyst similarly produced two phases of polymers. By contrast, the catalytic reaction of 2 with the Cp2ZrCl2/Red-Al combination catalyst produced a soluble polymer via redistribution/dehydrocoupling process.
