본성-양육 논쟁으로 본『태교신기』-전통 태교론 및 현대 유전학과의 비교-

이경하 ( Kyung Ha Lee ) 서울대학교 인문학연구원 2014 人文論叢 Vol.71 No.1

본고의 목적은 전통 태교론 및 현대 유전학과의 비교를 통해 『태교신기』의 가치를 적극적으로 재평가하는 데 있다. 서구에서 태교 및 태아기에 대한 관심이 시작된 것은 20세기 후반에 유전학이 발달하면서 부터이다. 그런데 유교의 전통 태교 관념이 전제하는 ‘태아기’의 중요성은 서구의 본성-양육 논쟁이 전제한 ‘선천적’ 대 ‘후천적’이란 대립항의 설정 자체에 균열을 가한다. 그런 점에서 태교 관념을 체계적으로 이론화한 『태교신기』에 다시 주목할 필요가 있다고 보았다. 먼저 2장에서는 『태교신기』에서 ‘태’의 가변성에 대한 주장이 서구의 본성-양육 논쟁이 도달한 결론이나 현대 유전학이 이룬 성과와 맞 닿아 있다는 점을 논증하였다. 『태교신기』는 태아기 교육이 중요한 이유를 ‘태’가 가변적인 존재라는 것, 태는 어머니와 단단히 연결되어 그 영향을 받는다는 것, 태아기의 경험이 생리적으로뿐만 아니라 심성 면에서도 출생 이후에 막대한 영향을 미친다는 점에서 찾았다. 태아기의 무궁한 변화 가능성에 주목하는 한편, 출생 이후 교육에 의한 변화 가능성이 매우 미미하다고 본 것은 『태교신기』의 성과이자 한계라고 할 수 있다. 3장과 4장에서는 『태교신기』가 ‘태’의 생물학적·유전학적 측면에도 주목함으로써, 주로 도덕적 문제에 치중했던 유교 인성론이나 기존의 태교론과는 차별화된다는 점을 논의하였다. 『태교신기』에 보이는 남방인과 북방인의 비교, 쌍둥이에 대한 언급 등은 선행연구에서 그다지 주목하지 않았던 부분인데, 이런 대목들에서 발견되는 개체 및 개체군의 유사성과 차이에 대한 관심에 새롭게 주목하였다. 이로써 태에 대한 교육적 측면에 대한 통찰뿐 아니라 태 자체에 대한 생물학적 혹은 유전학적 문제의식을 배태하고 있다는 점에서도 『태교신기』의 학술적 가치를 읽어내고자 하였다. 『태교신기』는 ‘유전적 자질’과 ‘환경에 의한 변화 가능성’을 함께 갖고 있는 물질로서의 ‘태’ 자체에 주목함으로써, 주로 도덕적 문제에 치중했던 유교 인성론이나 전통 태교론과 차별화된다. Taegyoshingi, a hanja text written by the female author Sajugang Lee (1738~1821), is a theoretical treatise and manual that deals with ‘taegyo’, a set of traditional beliefs and regulations regarding prenatal development. The title can be read as ‘a new record (shingi) on taegyo’. Previous studies have approached this text from a medical perspective or have tended to focus on its underlying Confucian beliefs. However, the aim of this paper is to examine the ideas pertaining to biology and genetics that can be found in Taegyoshingi. Through such an approach, it is demonstrated that forming the core of taegyo theory is the notion that the ‘tae’ (fetus) is a physical entity which has its own nature, and that the surrounding environment and the act of nurturing can bring about its transformation. Sajugang Lee`s discussion on the importance of nurturing the fetus (in other words, the surrounding environment) was based on the assumption that ‘the fetus is subject to change’. The nature-nurture debate which has taken place during the past century has now evolved to the stage that the central discussion is no longer on whether it is the environment or genetic factors that determine an individual`s characteristics; now the discussion tends to focus on the issue of how the two factors are interrelated, as well as the flexibility/unmalleability of human nature. In other words, it involves a renegotiation of the relationship between nature and nurture, a new perspective that can also be observed in Taegyoshingi.

본 연구의 목적은 강원도 양양지역에 분포하는 소나무림을 대상으로 지상부 바이오매스와 수관층 연료특성에 대하여 분석하고자 하였다. 연구대상지는 강원도 양양군 현남면 하월천리 일대 소나무림으로 선정하였으며, 총 13본의 표본목을 벌채하여 분석하였다. 본 연구 결과에 의하면, 양양지역 소나무림의 줄기밀도(g·cm-3)는 0.347~0.409, 지상부 바이오매스 확장계수는 1.251~1.419의 범위로 나타났다. 지상부 연료량은 총 161.6 Mg·ha-1로 나타났으며, 줄기 126.4 Mg·ha-1, 가지 29.3 Mg·ha-1, 잎 5.9 Mg·ha-1로 나타났다. 수관층 연료특성 인자에 관한 연구에서는 수관화 확산 시 연소될 수 있는 연소가능 연료(잎~1 cm이하 가지)의 비율은 45.2%로 나타났고, 연료량을 수관체적으로 나눈 연소가능 연료밀도(kg·m-3)는 평균 0.178로 나타났다. 본 연구의 결과는 소나무림의 바이오매스 및 탄소 흡수량 추정과 수관화 위험성을 연료적 관점에서 평가하는데 있어 유용한 기초자료가 될 것으로 사료된다. The objective of this study was to analyze the above-ground biomass and crown fuel characteristics of Pinus densiflora stands in Yangyang, Gangwon province. A total of thirteen representative trees were destructively sampled in Yangyang region. The results showed that the stem density (g·cm-3) was 0.347~0.409, whereas the above-ground biomass expansion factors ranged from 1.251~1.419. In terms of crown fuel biomass, the above-ground biomass was 161.6 Mg·ha-1 while the stem biomass, branch biomass and needle biomass were 126.4 Mg·ha-1, 29.3 Mg·ha-1 and 5.9 Mg·ha-1, respectively. Needles and twigs with less than 1 cm diameter accounted 45.2% of the total crown fuel load. The available crown bulk density, which was calculated by dividing the crown fuel load to the crown volume, was 0.178 kg·m-3. The results of this study on the biomass and carbon stocks estimation of the Pinus densiflora together with the crown fire hazard assessment based on crown fuel loads are very significant information for the forest managers.

Rice is the single most important crop in Lao PDR. In the 2000 rice production year, total rice production in the Laos reached 2.2 million tons. This is regarded as sufficient to provide national self-sufficiency. The rice harvested area in 2000 was approximately 719,500ha and represented 80% of cropped land area. Approximately 82% of production was from wet season cropped and 18% was from the irrigated dry season. Grain yield per unit area vary from 1.68 to 4.39 ton/ha in the wet season environment. However, the highest grain yield (4.39 ton/ha) obtained from the dry season irrigated crop. Higher yields and reduced year variation in production can be expected with the further intensification of production systems in the low land environments. However, further imporvements in production will be dependent on higher levels of inputs and further alleviation of some the production constraints.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Berchemia berchemiaefolia is a rare and endangered species and important as a honey resource. The purposes of this study were to investigate physical environmental factors and the population and community structure of Berchemia berchemiaefolia stands at Mt.Gunja in Sogrisan National Park in Chungcheongbuk-do. The B berchemiaefolia stands belonged to deciduous forests in mid-temperate zone and were 5~25˚ in slope 30~90% in rock ratio and 6.37 in soil pH. They had 656 trees within the area of 36 ha and their average density was 18.2 trees per ha. The trees within the stands were 11.8m in tree height 22.6 cm in DBH and 56 years old. The number of branched stems was the maximum 8 and 32.9% of the trees were branched. B. berchemiaefolia trees over 12cm diameter occupied 89.9% but young B. berchemiaefolia did only 11%. The structure of B. berchemiaefolia stands were classified into three groups as Acer pseudo-sieboldianum & A. mono community group A. pseudo-sieboldianum & Quercus aliena community group and B. berchemiaefolia & Quercus serata community group. The mean importance value of B. berchemiaefolia was 10.9% while species diversity of the community ranged 0.77~1.31 and interspecific competition ranged 0.78~0.94. The dominance of the community ranged of 0.07~0.29 and the evenness ranged 0.71~0.93. Although B. berchemiaefolia was dominant in the habitat but the species was already in natural successional stage to cornus controversa or Ulmus davidiana var. japonica.

The aim of this study was to evaluate the microleakage of teeth according to root canal preparation with & without apical enlargement in various size of apical foramen. 60 extracted one canal roots were cross-cutted at 5 mm from root apex and divided into two groups according to their apical foramen size of large (L) and small (S). Each group was subdivided into two groups accordance with their cross-sectional configuration at 5 mm from apex, round (R) and ovoid (O); SR Group, SO Group LR Group, LO Group. Each group was shaped in .02 taper by Quantec series Nickel-Titanium (NiTi) rotary file, obturated by lateral condensation method. Leakage was measured using a fluid transport model under 40cmH₂O pressure. After the leakage test, blocks which had showed the leakage retreated with .04 taper and ,06 taper and evaluated the degree of fluid filtration in each group. The data was analysed statistically using chi-square test and fisher's exact test. The results obtained were as follows : 1. Significant difference in leakage was found in groups which had different apical foramen size in .02 taper instrumentation (p < 0.05), but not in .04 taper instrumentation (p > 0.05) 2. The difference in microleakage according to the shape of canal was not evident at 5 mm from apex (p > 0.05). 3. There was correlation between .02 taper instrumentation and .04 taper instrumentation in LR group, LO group (p < 0.05). 이 연구의 목적은 근단공의 크기가 다양한 치아에서 근단공 확대의 유무에 따른 근관성형시 치아의 미세누출을 평가하기 위함이다. 1근관 치아 60개를 치근첨 상방 5mm에서 절단후 각 치아의 근단공 크기에 따라 큰 근단공 (L) 작은 근단공 (S)으로 나누었다 이 두 군을 치근첨 상방 5mm의 횡단면상 근관의 형태로 원형 (R)과 난형 (O)으로 나누었다(SR, SO, LR, LO). 각 군은 Quantec series Nickel-Titanium (Ni-Ti) rotary file을 이용하여 .02 taper로 성형 후 측방가압법으로 충전하였다. 누출은 40cmH₂O 압력하에 fluid transport method로 측정하였다. 측정 후 누출이 있는 시편은 .04 taper와 .06 taper로 재근관치료 하여 다세 미세누출을 평가하였다. 통계학적으로 chi-square test와 fisher's exact test를 이용하였다. 결과는 다음과 같다. 1. .02 taper로 성형한 군에서는 근단공의 크기에 따른 미세누출은 통계적으로 유의성이 있었고 (p < 0.05) .04 taper로 성형한 군에서는 통계적으로 유의한 차이를 보이지 않았다 (p > 0.05). 2.근첨 상방 5 mm에서 근관단면의 형태에 따른 미세누출은 통계적으로 유의하지 않았다 (p > 0.05). 3. LR group과 LO group에서는 .02 taper로 성형한 군과 .04 taper로 성형한 군사이에 유의한 차이를 보였다 (p < 0.05).

본 연구는 직업관련 극 놀이 활동이 유아의 진로인식 및 자아개념 향상에 효과적인지를 확인하는데 목적을 두었다. 이에 따라 서울 소재 B, Y 국공립 어린이집 2개 반에서 만 5세유아 40명을 무선 선정하여 실험집단과 통제집단에 각각 20명씩 배정하였다. 실험집단 유아들을 대상으로 직업관련 극 놀이 활동을 12회 실시하였고, 통제집단 유아들에게는 누리과정활동을 하였다. 본 연구에서 사용한 검사 도구는 유아의 진로인식 검사(임연정, 2011)와 유아용 자아개념검사(이경화, 고진영, 2014)를 사용하였다. 수집된 자료는 SPSS WIN 22.0 프로그램을 사용하여 사전, 사후간 독립표본 t-test를 실시하였다. 연구결과, 직업관련 극 놀이 활동을 실시한 실험집단이 일반누리과정을 실시한 통제집단보다 진로인식과 자아개념에 있어서 더 향상이 나타나 실험이 효과적이었음이 확인되었다. 이러한 연구결과를 통해 유아교육현장에서 유아의 진로인식과 자아개념향상을 돕기 위한 교수학습방법으로 직업관련 극 놀이활동이 활용될 수 있음을 시사한다. The purpose of this research was to identify how job-related dramatic play affect career-awareness and self-concept of young children. For this research 20 children in each experimental group and control group, total 40 children were selected. They were 5-year-old children going to 2 classes of B and Y public kindergarten located in Seoul. 12 times of dramatic play activity were played for children in experimental group and for control group they had Nuri curriculum which has no special treatment. In terms of research tool used in this study, career-awareness test of children (Yim Yun-jeong, 2011) and self-concept test for children (Lee Kyung-hwa & Goh Jin-young, 2014, unpublished) were used. The collected data was analyzed by using SPSS WIN 22.0 program and t-test for pre and post independent samples was implemented. As a result of this research children in experimental group who had gone through job-related dramatic play activity had positive influence on improvement of their career-awareness and self-concept compared to ones in control group who had gone through general Nuri curriculum. This conclusion implies that job-related dramatic play activity can be a meaningful teaching tool for developing children’s career-awareness and self-concept.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

The pH changes in 4 small cavities prepared at the facial inner dentin and lingual outer dentin of the cervical and apical portion of root filled with calcium hydroxide pastes were investigated. Forty extracted permanent teeth with single canal were instrumented with step-back method, and then 4 small cavities were prepared. Two inner dentin cavities were cut a distance of about 1.0㎜from the canal wall and two outer dentin cavities were cut to a depth of about 0.5㎜ from the root surface. Root canals and prepared cavities were flushed with 17% EDTA, and then irrigated with 5% NaOCI to remove smear layer. Teeth were randomly divided into four groups. Control group was not filled and the remaining other groups were filled with mixture of calcium hydroxide and distilled water, Vitapex(r) paste and Pulpdent(r) paste respectively. The pH change of the dentin in each cavity was measured at 0, 1, 3, 7, 14, 21, 28, 60, 90 days with pH microelectrode(WPI Co., USA). The results were as follows : 1. The groups obturated with Pulpdent(r) paste and Aqueous calcium hydroxide produced the increased pH level at 1 day and maintained plateau over next 3weeks and decreased after 3weeks. 2. The group obturated with Vitapex(r) paste observed no significant pH change until 2weeks and slight increased pH at 3weeks and sequential increasing after 3 weeks. But, the pH in the group obturated with Vitapex(r) paste remained significantly below the pH measured in the other two experimental groups(P<0.05). 3. All experimental groups showed pH level similar to control group after 28 days. 4. The pH of outer dentin is slightly higher than that of inner dentin. There is no significant difference in pH level between apical and cervical dentin throughout the duration of the experiment, though apical dentin showed slightly higher pH than cervical dentin at 1 day(P<0.05).
