이 논문의 목적은 외국어 학습자가 대화체와 설명체 텍스트를 읽기를 하는 동안, 텍스트 유형이 쓰기에 있어서 어휘향상에 어떻게 영향을 주는 지를 밝히는데 있다. 실험집단은 3개의 그룹으로 나뉘어졌다. 첫번째 그룹은 대화체 텍스트를 읽었고, 두번째 그룹은 설명체 텍스트를 읽었다. 한편, 세번째 그룹은 대화체와 설명체 글을 번갈아 가며 읽었다. 학습과정이 끝난 후, 어휘 테스트를 통해 집단 간의 비교를 하였고, ETS 에세이 평가에 나타난 평가 결과를 토대로 어휘에 나타난 특징을 분석하여 비교 하였다. 실험 결과는, 학습자의 모르는 어휘에 대한 이해에 있어서, 설명체 텍스트가 대화체 텍스트보다 우수하다는 것을 증명하였다. 더욱이, 대화체와 설명체를 동시에 읽은 집단이 대화체만 읽은 집단이나 설명체만 읽은 집단보다 어휘 향상에 이어서 더 우수함을 보여 주었다. 한편, ETS 에세이 쓰기에 나타난 결과는 상대적으로 설명체 글의 학습자가 틀린 오류가 가장 많았다.

The aim of this study was to investigate the alterations in meningeal blood flow by stimulation of trigeminovascular system. An open cranial window was prepared on the right parietal bone of male Sprague-Dawley rats. Trigeminovascular system was stimulated by electrical stimulation of trigeminal ganglion (ETS), somatosensory (whisker) stimulation, or topical applications of capsaicin and neuropeptides including substance P and calcitonin gene-related peptide (CGRP). Neonatal capsaicin pretreatment was performed with subcutaneous administration of capsaicin (50 mg/kg) within the first 24 hours after birth. Changes in regional blood flow of dural artery (rDBF) and pial artery (rPBF) were continuously measured through the cranial window by laser-Doppler flowmetry. Both ETS and capsaicin caused a chain of alterations in rPBF and rDBF responses, i.e., an immediate transient decrease followed by rapid and marked increase in rPBF, which were significantly attenuated not only by pretreatments with L-733,060, a $NK_1$ receptor blocker, $CGRP_{8-37}$, a $CGRP_1$ receptor blocker, and 7-nitroindazole monosodium salt (7-NINA), a neuronal nitric oxide synthase inhibitor but also by neonatal capsaicin treatment. Exogenous neuropeptides including substance P and CGRP increased the meningeal blood flow, which was significantly attenuated not only by pretreatment with L-733,060 and $CGRP_{8-37}$, respectively, but also by pretreatment with 7-NINA. The rPBF response to whisker stimulation was significantly attenuated not only by trigeminovascular system injuries including nasociliary nerve denervation and neonatal capsaicin treatment but also by pretreatments with L-733,060, $CGRP_{8-37}$ and 7-NINA. These results suggest that the stimulation of trigeminovascular system causes prominent alterations in meningeal blood flow, and that neuropeptides as well as nitric oxide in the trigeminovascular system are importantly implicated in the regulation of meningeal blood flow.

We give conditions so that a polynomial be factorable through an $L_{\gamma}({\mu})$ space. Among them, we prove that, given a Banach space X and an index m, every absolutely summing operator on X is 1-factorable if and only if every 1-dominated m-homogeneous polynomial on X is right 1-factorable, if and only if every 1-dominated m-homogeneous polynomial on X is left 1-factorable. As a consequence, if X has local unconditional structure, then every 1-dominated homogeneous polynomial on X is right and left 1-factorable.

Objectives: We surveyed the prevalence of smoking among the adolescent population and analysed the correlation of the two exposure biomarkers-concentration of blood cadmium and urinary cotinine-to the smoking status. Methods: Subjects were 193 middle and high school students in Chungnam province. Blood cadmium and urinary cotinine were compared by sex and smoking status. Smoking status were classified by either the concentration of urinary cotinine or subjective answering as a smoker in the questionnaire. Results: Smoking prevalence was 24.6%, 36.2% and 6.7% among all subjects, male and female subjects, respectively. Average smoking amount was 17.5 and 1.5 cigarettes per month among the male subjects and female subjects, respectively. Mean concentration of urinary cotinine among the male subjects was $135.57{\mu}g/{\ell}$, and that of female subjects was $116.59{\mu}g/$. Direct smokers showed higher concentration of urinary cotinine than those of indirect smokers, and subjects with higher urinary concentration showed higher prevalence of smoking, too. Mean concentration of blood cadmium was $0.0572{\mu}g/d{\ell}$ among the male subjects, and $0.0693{\mu}g/d{\ell}$ among the female subjects. Among the male subjects, both exposure biomarkers showed significant correlation to the smoking status, but among the female subjects urinary cotinine did not show significant correlation to the smoking status. Conclusion: Concentrations of these two biomarkers suggested that this population had significantly high evironmental tobacco smoking(ETS) and efficient stop-smoking programs to reduce ETS should be directed to this population.

The feasibility of the particle-in-cell (PIC) method is assessed to simulate the non-collective phenomena like non-collective Thomson scattering (TS). The non-collective TS in the laser-plasma interaction, which is related to the single-particle behavior, is simulated through a 2D relativistic PIC code (XOOPIC). For this simulation, a non-collective TS is emitted from a 50-50 DT plasma with electron density and temperature of n_e = 3.00 × 10¹³ cm^-3 and T_e = 1000 eV, typical for the edge plasma at ITER measured by ETS system, respectively. The wavelength, intensity, and FWHM of the laser applied in the ETS system are λ_i,0 = 1.064 × 10^-4 cm, I_i = 2.24 × 10¹⁷ erg=s·㎠, and 12.00 ns, respectively. The electron density and temperature predicted by the PIC simulation, obtained from the TS scattered wave, are n_e,TS = 2.91 × 10¹³ cm^-3 and T_e,TS = 1089 eV, respectively, which are in accordance with the input values of the simulated plasma. The obtained results indicate that the ambiguities rising due to the contradiction between the PIC statistical collective mechanism caused by the super-particle concept and the non-collective nature of TS are resolved. The ability and validity to use PIC method to study the non-collective regimes are verified.

문화콘텐츠 산업은 지식기반 핵심산업으로, 정보통신기술에 인간의 창의성, 상상력, 감성, 스타일을 투입하여 문화콘텐츠기반 경제사회로 전환하고 있다. 문화산업은 문화전쟁이라는 커다란 변화속에 콘텐츠파워(contents power)로 급속히 변화하고 있으며, 이러한 변화의 추세속에서 우리 문화콘텐츠는 아시아를 넘어 각국으로 진출을 시도하고 있다. 그러나 현재 제한된 현지시장정보와 지역특성을 반영한 문화전반에 대한 이해 부족으로 많은 어려움을 겪고 있다. 이에 문화콘텐츠 글로벌 네트워크 구축을 통하여 문화콘텐츠의 지속적인 수출확대와 신규시장개척의 교두보 역할을 수행할 수 있는 문화콘텐츠 지역전문가 양성이 요청된다. 본 논문에서는 진출 대상 국가의 문화산업 리딩그룹을 국내에 초청하여 우리나라 콘텐츠를 경험케 함으로써 자국 내에서 친 한류 지속화 기반 및 수출확대를 지원하는 초청연수 및 한국기업의 해당국 파견연수, 한국내 체류하는 유학생 연수에 대한 교육지원시스템, ETS-CS(Educational Training System for Contents Specialist)을 설계하고 이를 현장에서 적용한 사례를 분석하여 향후 더 나은 시스템으로 활용도를 높이고자 한다.

This study was conducted to compare two biomarkers of environmental tobacco smoke (ETS); urinary cotinine and 1-hydroxypyrene-glucuronide (1-OHPG). Urine samples were collected from 102 junior high school students. Urinary cotinine was determined by GC and urinary 1-OHPG was assayed by synchronous fluorescence spectroscopy (SFS) after immuno-affinity purification using monoclonal antibody 8E11.(omitted)

After the Kyoto Protocol has been ratitied in Feb. 16 2005, the developed countries which is involved in Annex-1 have tried to mitigate GHG to the reduction objective. To accomplish this objective, EU developed EU-ETS, CDM project, and so on. Korea has faced pressure to be a member of Annex-1, because Korea and Mexico are only non-Annex-1 countries in the OECD nations. This study is intended to examine unfolding transition on negotiations of Conference of Parties(COP), the Kyoto Mechanism referred as a cost-effective tool to meet a targeted level of greenhouse gas decrease, and trends in responses of developed countries to the Kyoto Protocol, and finally suggests legal and politic counterplans responding to the United Nations Framework Convention on Climate Change(hereafter, UNFCCC).

우리나라 일부 건강한 유아를 대상으로 Mn-SOD Val16Ala, GSTP1 Ile105Val, GSTT1 present/null, GSTM1 present/null 유전자 다형성 분포를 살펴본 결과, Mn-SOD Val/Val형, GSTP1 Ile/Ile형, GSTT1 null 형, GSTM1 null 형이 주된 (major) 유전자형인 것으로 나타났다. 이 중 Mn-SOD Val/Val형은 Val/Ala 또는 Ala/Ala형에 비해 소변 8-OHdG 수준이 유의적이지는 않으나 높은 경향을 나타내었고, GSTP1 Ile/Ile형은 Ile/Val 또는 Val/Val형에 비해 소변 8-OHdG 수준이 유의적으로 낮았다. 간접흡연에의 노출 여부와 간접흡연-유전자 다형성의 상호 작용이 산화손상지표에는 유의적인 영향을 미치지 않는 것으로 나타났다. 이상의 결과로 볼 때 건강한 유아에서 GSTP1 Val allele 보유한 경우 산화적 손상에 대해 취약할 수 있음을 제시하며, 추후 대규모 연구를 통한 검증 및 이들 유전자형을 보유한 대상자를 위한 효과적인 영양 중재방안에 대한 고려가 필요할 것으로 사료된다.
