This study is purposed to specifically present and suggest two of the five aspects of the existing framework using data recorded by science class teachers. Mortimer and Scott (2003) viewed teaching purposes, content, communicative approach, patterns of discourse, and teacher intervention as five aspects of classroom discourse analysis, analyzed for secondary science classes. In this study, four episodes were extracted from elementary science classes, the entire analysis was conducted, and the analysis frame developed in this study was applied. The results of the study showed that elementary science classes were analyzed differently according to class flow and the score of the Reformed Teaching Observation Protocol (RTOP). In addition, the analysis framework presented in this study and the score of the RTOP were slightly consistent.

이 연구는 전남 신안군 상태도에 위치한 상서고분군 축조에 사용된 석재들에 대한 암석학적 특성과 채석 등 유통과정에 대해 고찰하고자 하였다. 고분 축조에 사용된 석재들에 대한 암석학적 특성 연구는 외관적 관찰에 의한 암석기재적 연구와 편광현미경 하에서 암석의 광물조성과 조직특성에 대한 연구 및 암석의 주성분 함량조성을 통한 지구화학적 연구를 수행하였다. 이 연구들과 함께 주변지질들과 관련하여 고분석재들의 채석과 이송 등에 대한 연구도 병행하였다. 고대로부터 신안군 일대는 한국-중국-일본을 연결하는 고대 해상교통로에 중요한 위치를 점하는 것으로 알려져 고분 축조에 사용되었던 석재 연구는 고대 해양사 측면에서 의미를 지닌다고 할 수 있다. 기재적 관찰에서 석재들은 중성암맥 기원인 안산반암을 제외하고는 대부분이 응회암류에 해당한다. 이들은 라필리응회암과 세립질 응회암으로 구분되는데 대부분 세립질 응회암에 속한다. 응회암 구성입자들은 각상에서 초각상이고 분급도는 불량하다. 세립질 응회암들은 매우 치밀한 조직을 보유하고 특히 라필리응회암의 불규칙한 이탈흔들은 타포니(tafoni)와 관련될 가능성이 있다. 응회암의 입자들은 사장석편과 암편 등이 주를 이루며 크기 범위가 광범위하다. 사장석들은 알바이트 쌍정이 잘 나타나고 격자쌍정을 이루는 미사장석들도 출현한다. 응회암의 치밀한 조직은 부분적으로 속성작용과 관련되는 것으로 여겨지며 다양한 풍화정도를 보인다. 또한, 미세한 석영맥들이 응회암들을 종횡으로 관통하고 있다. 상기한 상서고분군 석재들에 대한 주성분 원소 함량에 대한 지구화학적 연구에 의하면, 이들 응회암은 화산암류 관점에서 산성암계열에 근접한 중성암 계열 및 산성암계열에 해당시킬 수 있다. 이러한 함량분포 특성 상, 이 응회암들은 두 가지 군으로 나눌 수 있다. 그리고 TAS(total alakali vs silica) 분류에서 이 응회암들은 저알칼리암 계열에 도시된다. 고분축조에 사용된 응회암들은 주변의 암석과 매우 유사하며 석재들 자체도 광물조상과 조직특성에서 서로 유사정도가 높다. 일반적으로 응회암들은 판상특성, 가공의 용이성 및 상대적인 견고성으로 고분과 건축 등에 많이 이용되어 왔다. 이러한 결과들을 기반으로 고분축조에 사용된 응회암들은 산성암계열에 근접한 중성암계열 및 산성암계열 기원을 가지며 주변 암석에서 채석·이송된 것으로 추정된다. This study considers on petrological characteristics and distribution to building stones of Sangseo tumuli in Santae Island, Shin-an, Jeonnam. The petrological study on the stones includes visually petrographical descriptions, textural study by polarized microscope and geochemical analysis. Along with the study, distribution routes of the stones were traced based on the regional geology of the island. Since ancient times, the study area is important as a base on international maritime traffic route. Therefore, studies on the tumuli are meaningful for ancient maritime history. In visual observation, above building stones are of tuffs except for an andesitic porphyry considered as intermediate dyke. The tuffs are assigned to lapilli and fine ones. Their grains are poorly sorted and angular to very angular in roundness. In particular, the fine tuffs show very dense textures and take up the most part of the building stones. In addition, the stones have irregularly removed depressions inferred as the linkage to tafoni, in lapilli tuffs particularly. The tuffs are mainly of plagioclases laths, rock fragments and matrices and ranges widely in grain size. The plagioclases show mostly unambiguous albite twin. And, microcline crystals are observed in the tuffs too. Matrices in the tuffs are considerably dense and weathered. Dense texture in the rocks are related to diagenesis in part. In addition, thin quartz veins irregularly intruded the rocks vertically and horizontally. According to the geochemical analysis of building stones of above tumuli, the stones might be intermediate rock series near acidic rock ones and acidic rock ones in the correspondence of volcanics. Therefore, the tuffs probably grouped as two types and are assigned to subalkaline rock series by TAS diagram. Most the building stones mutually resemble in visual and textural characteristics. Tuffs are generally platy, easy in use and relatively hard. In addition, rocks very similar to the building stones are widely distributed in surrounding area. Synthesizing above results, it is considered that tuffs used in tumuli building are corresponded to intermediate rock series near acidic rock ones and acidic rock, and got from surrounding rocks.

The purposes of the research were to analyse the activists' appraisals and demands about undertakings of nongovernmental organizations especially in Gwangju and to propose the developmental alternatives. The levels of citizens' recognition about NGO are low, but their contribution appraisals are relatively high. Activists want more concerns and participations of citizens. Also they need systematic training and educations for competency enrichment. The organizations' mechanisms must be changed to more effective systems and support community sufficiently for welfare empowerment. Also community members, organizations and activists endeavor collaborately for welfare development.

The purposes of this article are to find out general trends of couples' role expectancies and role conflicts according to wives' employment, to estimate the differences of role expectancies and role conflicts according to sociodemographic and family-related variables and to analyze the effects of significant variables and role expectancies influencing on role conflicts. The samples were selected from the employed wives and their husband, living in Kwang-ju. 169 couples' data were used in final analysis. The data were analyzed by frequency, percentage, mean, paired t-test, one-way ANOVA, Duncan-test, Chronbach's α, and multiple regression. The results are as follows: 1) Employed wives and their husbands' role expectancies were higher than their role conflicts. Husbands' role expectancies were higher than wives' but wives were higher than husbands in role conflicts. Especially, child rearing and housework demensions were relatively higher than others in role expectancies and conflicts. 2) In the case of husbands, role expectancies were significantly different according to the perception of family/employment importance and role conflicts were significantly different according to sex role attitude, support to wives' employment. In the case of Wives, role expectancies were significantly different according to education, husband's income, her own income, job, unfairness perception, support of husband and parents in-law, job satisfaction. Role conflicts were significantly different according to marriage year, communication time and satisfaction with spouse, husband's housework aid, unfairness perception, husband's support to spouse's employment, and job satisfaction. 3) From the regression analysis, it was found that husbands' role conflicts were influenced by communication satisfaction with spouse, sex role attitude, perception of family/employment importance, and role expectancies. Wives' role conflicts were influenced by communication satisfaction with spouse, husband housework aid, unfairness perception, sex role attitude, husband's support to wife's employment, and role expectancies. In conclusion, It is very important to reduce dual-career couples' role conflicts with high communication satisfaction with spouse, advanced sex role attitude, husband's support, housework aid, and low role expectancies.

This study was carried out to know the growth rate of height and weight in Korean children which was conducted on semi-longitudinal research method. For this study, health records of the sample group that carry information for the period from their first grade of elementary school to the third grade of high school were used, 120 males and 120 females who became third grade of high school in 1994 were selected at random from each of the four cities; Seoul, Chonan, Kumi and Eumsung. Among 917 candidates, 460 males and 457 females born between March 1976 and December 1976 were finally selected as a sample for the purpose of this research. The results are as follows; 1. Measurement of the physique Both male and female samples showed constant growth in height and weight. Male grew from the range of 115.8±4.8㎝ at the age of 6 to 171.5±5.6㎝ at 17 while females grew from the range of 114.6±4.7㎝ to 158.9±5.1㎝. The Weight of males rose from the range of 19.9±2.5Kg at the age of 6 to 62.5 ±8.1Kg at 17 while that of females increased from the range of 19.3±2.4Kg to 54.1±6.9Kg. 2. Growth and Nutritional Indices The study revealed that relative weight of the sample group increased as they grew older. The Kaup index also showed an increase in line with the advancement in their ages, and exceeded 2.0 at the age of 15 for males and at the age of 14 for females. The Rohrer index, on the other hand, showed a declining trend for the first several years but began to increase at the age of 13 for males and at the age of 11 for females. 3. Comparative analysis with similar regardless that were performed using sample groups born in 1965 and 1970 revealed the followings; ① Height - The average height of male samples(born in 1976) under this survey was bigger than that of male samples born in 1965 in their respective age from 6 to 17. - The average height of male samples born in 1970 was bigger than that of male samples born in 1970 from 6 to 14 but showed no difference after 15. - Female samples born in 1976 showed height that was bigger than the other sample groups born in 1965 and 1970 in their respective age from 6 to 17. ② Weight Both male and female samples under this survey weighed more than their counterpart sample groups born in 1965 and 1970 in their respective age. 4. The Maximum Growth Age was 12.3 for males and 10.4 for females. Males grew 5.92±2.77㎝ a year on an average when they were 12 and 13 years old while females grew 5.93±2.69㎝ when they were 11 and 12 years old. In conclusion, the study revealed that like in other countries males and females experienced the second growth spurt during their adolescence and relatively slow growth thereafter. Unlike height which showed constant growth, weight varied; there were incidences where females even experienced weight loss after years of diminishing growth rate in the wake of the adolescence.
