조성연 한국방송통신대학교 미래원격교육연구원 2008 평생학습사회 Vol.4 No.1
본 연구의 목적은 성인학습자의 자기조절학습전략 프로그램을 개발하고 그 효과를 검증하는 데 있다. 방송대 학생 요구조사, 전문가 자문, 학습전략 선행연구 조사 등을 통해 성인학습자 학습전략요인으로 집중력 및 기억전략, 학습동기, 학업불안, 시간관리, 인적・물적 자원활용의 5가지 하위요인을 설정하였으며 이는 인지적, 정서적, 행동통제요 인들을 포괄하는 내용으로 구성되었다. 이러한 내용으로 구성된 프로그램을 방송대에 재학 중인 성인학습자를 대상으로 워크샵의 형태로 실시한 후, 조성연과 박미진(2006) 이 개발한 학습문제진단심리검사를 사용하여 프로그램이 학습전략을 증진시키는데 효과가 있는지를 검증하였다. 학습문제진단심리검사의 사전검사 점수를 공변인으로 하여 사후검사 점수를 변량분석한 결과, 프로그램에 참가한 실험집단의 성인학습자들은 참가하지 않은 통제집단의 성인학습자들보다 집중력 및 기억전략, 시간관리, 자원활용의 하위 요인별 점수의 평균이 유의미하게 높게 나타났으며 학업불안 점수에서는 유의미하게 낮게 나타났다. 그러나 학습동기는 유의미한 차이를 보이지 않았다. 이 같은 결과를 통해 본 연구에서 개발된 학습전략 프로그램이 학습동기를 제외한 인지적, 행동조절능력 증진에 효과가 있음을 알 수 있으며, 추후 성인학습자의 학습동기 증진을 위한 심도있는 상담적 접근이 필요함을 시사한다고 볼 수 있다. The purpose of this study is to evaluate the effectiveness of a study strategy workshop on the study strategy problems diagnosis(Cho & Park, 2006) of adult learners. The workshop strategically incorporated concentration & memory, time management, test anxiety and study aids, study motivation to parallel of cognition, emotional, behavioral management, respectively. Adult learners participated in a study strategies workshop. Results suggested that participants in the workshop had a significant positive effect on the concentration & memory, time management, test anxiety and study aids, but no effect on the study motivation. Results indicate that study strategies of adult learners is amendable to change through developed program interventions except study motivation. This study has implication for improvement of study motivation to include effective counseling approach for adult learners.

영국의 초등학교 조기 취학을 통해 본 우리나라의 유아교육학제 개편 방향
조성연,김선영,Donn, Gari 한국유아교육학회 2006 유아교육연구 Vol.26 No.4
This article addresses problems related to the reorganization of the current Korean school ladder system. Presently, children enter a school at six years of age but considerable debate has been raised about the age-appropriateness of school entry for young children. This study examines the UK’s school ladder system whereby school is entered at 4 or 5 years of age. Since 1870s, children in the UK (England and Wales and -separately- Scotland) have entered school at four or five years of age. Other developed countries have adopted the age of six for school entry. Findings indicate that there are many problems associated with school entrance age in the UK, including the rationale, itself, for the age of entry; the age influence on children’s later academic achievement; the utility or a ‘reception class’; the continuity and progression of the curriculum from early years into primary school and beyond; and the effect upon young children’s development between the age of 3 years and 6 years. Based on these findings, this article concludes that, firstly, the school entrance age in Korea should be six and, secondly, that the new school ladder system should include early childhood education(between 3-6 years) as an integral component of the transfer to primary school. 최근 논의되고 있는 5세 초등학교 취학으로의 학제 개편 방향은 그 적절성에 관해 학계와 전문가들로부터 많은 논란과 우려가 제기되고 있다. 그에 따라 본 연구는 이러한 중요한 쟁점을 조명하기 위하여 오래 전부터 조기 취학제도를 채택하고 있는 영국의 유아교육관련 학제를 고찰하고자 하였다. 그 결과 영국 내에서도 조기 취학에 대한 많은 논쟁이 이어지고 있었으며 그와 관련하여 입학월령, reception class 및 취학 전 교육과 초등교육과의 연계성 등 다양한 문제점들이 파생되고 있었다. 이러한 영국의 사례를 통해 우리나라의 유아교육학제의 개편 방향은 우선적으로 아동의 발달을 고려하는 것이 전제되어야 하며, 6세 적령기의 초등학교 취학이 가장 바람직하다는 결론을 도출하였다. 이를 위해 3~5세의 취학 전 유아교육이 공교육화됨으로써 초등교육과 효과적으로 연계될 수 있는 유아교육학제로의 개편이 바람직하다.

조성연,이용교,방은령 한국청소년복지학회 2000 청소년복지연구 Vol.2 No.2
The purpose of this study was to investigate the female adolescent's meeting with adults for sex. The main contents of this study are focused to explore the definition, process and environment of the female adolescent's meeting with adults for sex and to propose the policy and prevention for it. Major findings of this study can be summarized as follows. a) The female adolescent's meeting with adult for sex is another type of prostitution. b) Female adolescents have met with male adult for money, play, and sex. c) Meeting was arranged by telephone club, internet chatting, street hunting, and of friends. The female adolescent's meeting with adults for sex should be decreased by active control and various protections.

Novel in situ chondroitin sulfate (CS) hydrogel was synthesized via phosphine-mediated Michael type addition reaction by mixing precursor solutions of both CS-acrylate and CS-tri(2-carboxyethyl)phosphine (TCEP)as an electrophile and a nucleophile, respectively. CS-acrylate and CS-TCEP were synthesized in advance by chemical grafting of acrylic acid and TCEP to adipic dihydrazide (ADH)-grafted CS. After verification of chemical grafting of TCEP to CS-ADH by phosphorous peaks in the proton nuclear magnetic resonance spectra (1H NMR) and Fourier transform infrared spectroscopy (FTIR), gel formation was evaluated with a tilting method under different pHs, temperatures and concentrations of the precursor solutions. Precursor solutions spontaneously turned into a gel within a minute to several hours depending on the solution conditions, where a basic pH and higher concentrations and reaction temperatures of the precursor solutions induced quicker gel formation. The fabricated CS hydrogel was thermally stable at low temperatures as observed by both differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA), and also swelled to equilibrium state, leading to 1 to 2 times increase in mass, where a basic medium induced more gel swelling than an acid one. The morphologies of the equilibrated swollen gel showed expansion of its polymer network having pores with a diameter of 13 to 16 μm in dehydrated state. The hydrogel released rhodamine B, a model drug, over approximately 10 h and had 1.08 MPa of compressive modulus for the 10% hydrogel. On the other hand, degradation of the CS hydrogel was controlled by the addition of chondroitinase ABC, along with the reduction of compression strength. The hydrogel had excellent in vitro biocompatibility both inside and on the surface of the CS hydrogel when tested with the live and dead assay of fibroblasts. From these experimental results, we concluded that when TCEP acted as a nucleophilic cross-linking agent of Michael type addition reaction in the synthesis of CS hydrogel, the CS hydrogel demonstrated adequate physicochemical and biological properties.
