Die Geschichte des Kostums steht in unmittelbarem odor mittelbarem Zusammenhang mit der allgemeinea historischen Entwicklung derjenigen Lander und sozialen Schichten, die das kulturclle Gesicht und damit auch die Entwicklung der Mode einer Epoche bestimmen. Im 19. Jahrhundert war das Burgertum in Europa die herrschende soziale Schicht und daher auch modisch tonangebend. Die Mode des Burgertums zeigte demokratisierende Tendon-zen: Vereinfachung der Ausstattung und der Formen, wobei sich die Proportionen der Kleidung so gut wie moglich den des Korpers anpaBten. Die Herrenmode beugte sich zunehmend den For-derungen nach ZweckmaBigkeit; dab galt zumindest fur den Tagesanzug, der immer mehr zum Arbeitsanzug wurde und sick damit der Mannerkleidung der arbeinden Schicht annahrte. Die Industrialisierung trug ebenfalls dazu bei, daB die modischen und sozialen Previlegien in der Kleidung sich verminderten : die Textil-und Konfektionsindustrie muBte sich zwangs-laufig auf die Bedurfnisse der Massen und auf deren Wunsch einstellen. In der Herrenmode setzte sich die Tendenz zu funktionaler Einfachheit und Gradlinigkeit durch, d.h. funktional uberflussige Teile wie z.B. die Vielzahl der Kragen, Knopfreihen, uberlange SchoBe verschwanden ; an die Stelle der Farbenfreude trat ein einfaches, einhei-tliches Grau, Schwarz, Blau und Braun. Diese Vereinfachung wurde zum Ausdruck der zunehmenden Demokratisierung, wurde aber zugleich auch Voraussetzung fur eine neue Differnzierung des KlassenbewuBtseins. Zum Statussymbol wurden die auffalliges Erscheinen vermeidende Eleganz und das Arrangement der einzelnen Kleidungsstucke zu einem har-monischen Ganzen; elegante Kleidung weist ihren Trager aus als Kenner des Modetrends und damit als zugehorig zum Kreis der modeavancierten Schicht. Diese Ambivalenz bestimmt auch die Mode des 20. Jahrhunderts.

The purpose of this study is comparing cognitive development of elementary $4^{th}$ graders and cognitive demand of activities in lesson 'The mirror and the shadow.' Also, the researchers tried to reveal how cognitive development of elementary $4^{th}$ graders and cognitive demand of textbook activities affects the achievement of students. To study students' cognitive development, the researchers use GALT(Group Assessment of Logical Thinking). Piaget's scientific thinking is used to evaluate cognitive demand of textbook activities. With several experts in science education the researchers discussed which scientific thinking is contained in each activities. The results were followed as : (1) The third of activities are significantly affected by students' cognitive development. (2) The another third of activities are influenced by not only students' cognitive development but also other factors experimental instrument. (3) The environmental factors had meaningful impact on the other third of activities.

The purpose of this study was to explore North Korean immigrant elementary students' cognitive and affective characteristics related to science education. A total of 68 North Korean immigrant students enrolled in 3 to 6 grades and 133 South Korean students in 4 and 6 grades in 3 South Korean elementary schools participated in the study. A short version of Group Assessment of Logical Thinking(GALT) was used to investigate the students' levels of logical thinking, and the Enjoyment of Science Lessons Scale(ESLS) of the Test of Science Related Attitudes(TOSRA) was administrated to examine their attitudes towards science lessons. The statistical analysis of data revealed that the level of logical thinking of the North Korean immigrant elementary students was very low and that this was also the case for the South Korean students. Especially, the mean score of logical thinking of the North Korean immigrant 6 graders was much lower when compared with that of the South Korean counterparts. For both the North Korean immigrant students and South Korean students, the enjoyment of science lessons decreased as they progressed through higher grades. This decreasing trend, however, turned out to be more serious in the South Korean elementary students. Based on these results, suggestions were presented to help successful science learning of North Korean immigrant elementary students.

The purpose of this study is to investigate the interrelationships on integrated science process skills and Piagetian cognitive modes for high school students according to the different cognitive reasoning levels. About 509 high school students were randomly selected for the samples of this study. They were identified as concrete, transitional and formal operational stage with the scores of GALT(Group Assessment of Logical Thinking) developed by Roadrangka, Yeaney and Padilla(1982), and TIPS II(Test of Integrated Process Skills) developed by Burns, Wise and Okey(1983). The result of this study were showed that about 11.8% of the samples were in the concrete operational stage and about 24.4% of the samples were in the transitional stage, while about 63.8% of them were in the formal operational stage. It was also found that the achivement scores of the science process skills increase in accordance with the cognitive reasoning levels. The value of the correlation coefficient between science process skills and cognitive reasoning abilities was 0.49, which was significant at the 0.05 level. This finding seems to support previous research that the student's cognitive reasoning abilities appeared to have influenced student's scores of the science process skills No differences to the logical reasoning ability between male and female students according to each cognitive level were found except formal operational stage.

The primary purpose of this study was to assess understanding of concrete and formal operational science content by concrete and formal operational students in secondary school physical science classes. To carry out this study subjects were selected from junior high schools of over 2500 students, and they were identified as concrete, transitional, or formal operational using GALT(Group Assessment of Logical Thinking) developed by Roadrangka, Yeany and Padilla(1983). Instructional objectives were extracted from the science content taught during the second term of the academic year in the 7th, 8th and 9th grade, and they were classified as concrete or formal operational. Written test involving those objectives were constructed and administered. The results of this study suggested that formal operational thought brought deeper understanding to concrete science content as well as formal science content. Differential effects by sex on understanding of both concrete and formal science content were contradictory through the grade levels. Results of multiple comparison tests suggested that students categorized as formal operational demonstrated no better understanding of concrete science content than those categorized as transitional. However, they demonstrated better understanding of formal science content.

Background: Breast cancer is the most common malignancy in women worldwide, including Thailand, and is a major cause of mortality and morbidity, despite advances in diagnosis and treatment. Novel gene expression in breast cancer is a focus in searches for prognostic biomarkers and new therapeutic targets. Materials and Methods: The mRNA expression of novel B4GALT4, SLC35B2, and WDHD1 genes in breast cancer were examined in invasive ductal breast carcinoma (IDC) patients using quantitative real-time reverse transcription polymerase chain reaction (QRT-PCR). Results: Among these genes, increased expression of SLC35B2 mRNA was significantly associated with TNM stage III + IV of IDC (p<0.001). Hence, up-regulation of SLC35B2 may serve as a prognostic biomarker for poor prognosis, and is also a potential therapeutic target in breast cancer.

It is apparent to anyone who has taught science in secondary. schools that a substantial percentage of students find the subject difficult: What is the cause of difficulty? There is season to believe that part of this difficulty is associated with students' intellectual development as deserifed by Piaget. To investigate the difficulty students face with learning science in the light of Piagetian developmental theory, the stages of the intellectual development of the secondary school student s were assessed in this study using the instrument called Group Assessment of Logical Think ing (GALT). The results of this study showed that more than 60% of 7th and 8th grade students were Classified as concrete operational level. It was also found that only 20% of the students from 9th through 11th grade were formal operational stage, while about 40% of them were still at concrete operational stage. This study showed that. there was a significant main effect on the intellectual development of the students by grade. However, it showed that at 0.5 level of significance there was no main effect by sex although mean scores of male on the assessment were higher than those of female.

To examine the effect of students' Cognitive level upon their achievement on Science. the students' cognitive levels were tested by using GALT(Group Assessment of Logical Thinking) and examined the Correlation between the cognitive level and achievement According to the results, most students were still in the conerete level. Only 60% of 9th grade students could handle the logic of displacement volume. In case of proportional logic and logic of probability, only 40% of 9th graders could handle them. Only 10% of the students could understand Correlational logic. Cognitive level and students achievement were estimated to be in a very closely related. Students who were in a high cognitive level showed better achievement scores on knowledge, comprehensive, inquiry, and application items than those who were in low cognitive level. Therefore, this study suggests that the content of the current middle school science should be revised in away to match the students' cognitive level.

The purposes of this study were to find out the degree of formation of the concept of density for the junior high students. The changing pattern of concept in acquiring the concept of density and the degree of development of INRC transformation ability related to the concept of density were also analyzed according to cognitive level and teaching method. The results of this study were as follows. 1) The experimental group were more effective than control group in the formation of the concept of density. 2) Even though students had been taught the concept of density, the various types of preconception were remained and persisted. Especially, the students at concrete level had persisted misconceptions and these misconceptions had been changed to the other misconceptions. 3) In the degree of the formation of the transformation ability of INRC group related to the concept of density in solid phase, the experimental group developed much better on both the abilities of Reciprocal transformation, Correlative transformation and the abilities to manipulate two variables such as volume and mass than control group. 4) The correlation coefficient between GALT score and achivement of the concept of density was 0.67. The correlation coefficient between achivement of the concept of density and the formation the transformation of INRC group related to the concept of density was 0.78.
