본 연구는 Hernes 모형을 활용하여 출생코호트의 관점에서 최근까지 한국 사회가 경험한 혼인 및 출산 생애과정에서의 전반적인 변화 양상과 교육수준별 차이를 분석하고 있다. 분석 결과는, 첫째, 전반적으로 우리나라의 생애 혼인율이 매우 높은 수준이지만 상대적으로 가장 최근 출생코호트(1965~74) 남성의 경우 혼인율 감소폭이 다소 크게 나타나고 있음을 보여 주었다. 둘째, 출생코호트를 가로질러 관측된 생애 혼인율 감소는 추가적으로 교육수준별로 분화되는 모습을 보여 주었는데, 남성의 경우 저학력자 그리고 여성의 경우 고학력자의 생애 비혼 가능성이 높게 나타났다. 셋째, 출생코호트를 가로지른 출산 경험과 관련하여 첫째 및 둘째 출산에서는 출생코호트별 격차가 작은 반면 셋째 출산에서의 격차가 크게 나타남으로써 출생코호트를 가로질러 나타난 출산력에서의 양적 변화는 대체로 셋째 이상의 고순위 출산과 밀접히 연관됨을 시사하고 있다. 넷째, 출산에서의 교육수준별 격차와 관련하여 출산순위가 높아질수록 교육과 출산 사이에 보다 뚜렷한 역관계가 관측되었다. 마지막으로 본 연구의 분석 결과는 혼인 및 출산이 교육수준과 연계되는 방식이 다소 상이함을 보여 주었다. 남성과 여성 모두 최근의 출생코호트로 올수록 교육수준별 생애 혼인율에서의 격차가 커지는 경향을 보여 주지만 고순위 출산에서 관측되는 교육수준별 패턴은 최근 출생코호트로 올수록 교육수준별 격차가 오히려 감소하는 상반된 패턴을 보여 주었다.

Solvolyses of 3,4-dimethoxybenzenesulfonyl chloride (DSC) in water, D2O, CH3OD, and in aqueous binary mixtures of acetone, acetonitrile, 1,4-dioxane, ethanol, methanol, and 2,2,2-trifluoroethanol (TFE) have been investigated at 25.0 oC. Kinetic solvent isotope effects (KSIE) in water and in methanol and product selectivities in alcohol-water mixtures are also reported. The Grunwald-Winstein plot of first-order rate constants for the solvolyic reaction of DSC with YCl shows marked dispersions into separated lines for various aqueous mixtures. With use of the extended Grunwald-Winstein equation, the l and m values obtained are 1.12 and 0.58 respectively for the solvolyses of DSC. The relatively large magnitude of l is consistent with substantial nucleophilic solvent assistance. From Grunwald-Winstein plots the rate data are dissected approximately into contributions from two competing reaction channels. This interpretation is supported for alcohol-water mixtures by the trends of product selectivities, which show a maximum for ethanol-water mixtures. From the KSIE of 1.45 in methanol, it is proposed that the reaction channel favored in methanolwater mixtures and in all less polar media is general-base catalysed and/or is possibly (but less likely) an addition-elimination pathway. Also, the KISE value of 1.35 for DSC in water is expected for SN2-SN1 processes, with minimal general base catalysis, and this mechanism is proposed for solvolyses in the most polar media.

Teacher quality is a topic of international concern, as it impacts student learning and teacher preparation. This study compared the undergraduate secondary science teacher preparation programs from two universities in Korea with those of Oregon, USA. We examined the programs' structural curricular coherence, conceptual curricular coherence, and curricular balance. Structural curricular coherence was determined by examining the overarching goals of the institutions' programs, the organization of the programs of study in terms of meeting those goals, and outside bodies of evidence. All universities were in structural coherence for various reasons. Conceptual curricular coherence was determined by examining students' perceptions of the connection between their preparation and their clinical practice. In case of Korea, most students from both universities were not satisfied with their practical preparation. In the US, the students from both institutions felt well prepared to transition to inservice teaching. To determine curricular balance, we examined the institutions' preparation programs looking at the credit hours taken in the four main areas of the teacher knowledge base: GPK (General Pedagogical Knowledge), SMK (Subject Matter Knowledge), PCK (Pedagogical Content Knowledge), and CK (Contextual Knowledge). The total credit hours taken in each category was very similar by country but the application and field component in the USA was far greater than those of Korea where the focus was heavily on SMK and PCK. The main reason for these may be the nations' licensing and employment processes.

The knowledge based economy requires more and more people to learn new knowledge and skills in a timely and effective manner. These needs and new technology such as computer and Internet are fueling a transition in e-learning. According to specialist's opinion, imagination experience studying is generalized, and learning environment that language barrier by studying, multi-language studying Machine that experience past things that disappear through simulation, and travel area, and experience future changed state disappears is forecasting to come. This is previewing finally that it may become future education that education and IT, element of entertainment is combined. Already, became story that argument for party satellite of e-Learning existence passes one season already. e-Learning is utilized already in all educations that we touch by effectiveness by corporation's competitive power improvement and implement of lifelong education in educational institutions through present e-Learning. It is obvious that when see from our viewpoint which is defining e-Learning by one industry and rear by application to education as well as one new growth power about these, e-Learning industry becomes very important means that can solve dilemma of growth real form. Only, special quality of digital industry that e-Learning is being same with other digital industry and repeat putting out a fire rapidly, and is repeating sudden change that these evolution is not gradual growth of accumulation and improvement of technology that is appearing consider need to. In the meantime, we need to observe about evolution of Information Technology. Because there is some scholars who e-Learning's concept foresees to evolve by u-Learning.(although, a person who see that these concept is not more in marketing terminology by some scholars' opinion is). This u-Learning's concept means e-Learning that take advantage of ubiquitous technology as Ubiquitous-Learning's curtailment speech. Ubiquitous, user means Information-Communication surrounding that can connect to network freely regardless of place without feeling network or computer. There is controversy about introduction time regarding these direction, but e-Learning is judged to evolve by u-Learning necessarily. Because keep in step and age that study all contents that learner wants under environment of 3A (any time, any whrer, any device) by individual order thoroughly is foreseen to come in ubiquitous learning environment that approach more festinately.

A novel silicon-containing arylacetylene resin (MSAR) modified by dipropargyl ether of bisphenol A (DPBPA) and dipropargyl ether of perfluorobisphenol A (DPPFBPA) was prepared separately. The curing behaviors of modified resins, DPBPA/MSAR and DPPFBPA/MSAR, were characterized with differential scanning calorimeter (DSC). The kinetic parameters of modified resins were obtained by the Kissinger and Ozawa methods. The results of dynamic mechanical analysis (DMA) revealed that the glass transition temperature ($T_g$) of the cured DPBPA/MSAR reached $486^{\circ}C$. According to the thermogravimetric analysis (TGA), the decomposition temperature ($T_{d5}$) of the cured resins and char yield ($Y_c$, $800^{\circ}C$) decreased as the dipropargyl ether loadings increased, especially in air. With the same weight loading, thermal stability of DPBPA/MSAR was better than that of DPPFBPA/MSAR. The carbon fiber (T300) reinforced composites exhibited excellent flexural properties at room temperature with a high property retention at $300^{\circ}C$.

Students' alternative concepts of evolution are similar to misconcepts and disputes which scientists had in science history. The aims of this study are to analyze the elementary children's concept in evolution based on science history. Lee (2004)'s two tests were applied to 6th grade to investigate the children's evolution concepts and genetic concepts related to the historical development of the evolution concepts. The test results were analyzed in accordance with 4 stages of science history based on Lee (2004)'s method. These stages are divided to stage 1 (Before Lamarck), stage 2 (Lamarck), stage 3 (Darwin), stage 4 (After Darwin). The major results are as follows. Most of elementary school children are fixed to the stage 2. They usually do not show the consistency of evolution concepts in the three dimensional aspects such as mechanism, time, and subjects. Many children do not have concrete meaning of gene, inheritance, sexual reproduction, mutation and could not connect these concetps and process of evolution. Also, they believe the inheritance of acquired traits and spontaneous generation. Therefore it is confirmed that they still have similar misconcepts and disputes which scientists had in transition time between stage 2 and 3 and most of children already have strong Lamarckian thought acquired from daily life experience before learning about natural selection and evolution.

Objectives : A transition course of 'Introduction to Clinical Korean Medicine' was developed to meet the demands for better preparation for clinical application of Korean Medicine within the curriculum. A Korean Medical Classics curriculum reflecting such demands was newly designed. Methods : Based on the 'Introduction to Clinical Medicine(ICM)' course of the Medical School curriculum that follows the medical education guideline, the 'Introduction to Clinical Korean Medicine(ICKM)' course was designed and developed. The role of Korean Medical Classics was suggested in the process. Results : In the following course, Korean Medical diagnosis, diagnostics, patient intake methods reflecting the Korean Medical diagnostic system, clinical skills, basic skills, treatment planning, patient education, etc. are included. Faculty members of the basic sectors of the Korean Medical school will participate in this curriculum, of which a head will be appointed to overlook the curriculum. In the case of Korean Medical Classics, previous learning outcomes need to be reorganized based on clinical expression while clinical case studies need to be added to course material. A more active approach utilizing new pedagogic strategies and teaching methods should be taken. Conclusions : The Korean Medical Classics curriculum could effectively take on the introductory role to clinical Korean Medicine, successfully strengthening the connection between the basic and clinical Korean Medicine to improve learners' satisfaction.
