The work focuses on the chemical analysis of organic residues in archaeological soils. Particularly, the detection of manuring in archaeological soils can provide important information concerning early human behavior, diet, parasites, ecological adeptation. In this study, archaeological soils excavated at bunto-ri, Haenam and kumjang-ri, Kyungju were used to assess the possibility as indicators of ancient human activity in archaeological areas. The sampled soils were analyzed soil color, pH for their physical and chemical properties and GC/MSD to detect and quantify specific compound. The results showed that the sampled soils were normal pH(6.8~7.2) and soil color of light brown to yellowish brown. Also, the result from the GC/MS analysis indicated that their compounds were hexadecanoic acid, octadecanoic acid, nonadecane, docosanoic acid, methyl ester, teracosanoic acidand methyl este from bunto-ri site and 1-heptadecene, cyclotetracosane, tetracosane, cyclotetracosane,1-docosene, n-nonadecane, tetracosanoic acid methyl ester, cyclooctacosane, 1-nonadecene, eicosane, cyclotriacontane from kumjang-ri site. These compounds are not only normal soil materials but also animal lipid compounds. And the more scientific analysis of the soils will solve a curiosity for artificially incoming.

Few studies have dealt with the question of when Mt. Baekdusan became known as a volcano. Attention has been focused rather on the issue of establishing the boundary between the Joseon Dynasty and the Qing Dynasty than the scientific nature of Baekdusan as a volcano. It is only in the late Joseon Dynasty that Park Jong (1764), who was the scholar of the Gwanbuk region, authored the first travel journal on Mt. Baekdu and described poseok. Due to the scientific curiosity of Westerners on the existence of mysterious snow peak on the border, it was first introduced to the Royal Geographical Society by a British man, H.E.M. James in 1887, who revealed for the first time that Mt. Baekdu is a dead volcano, and that the white color on the top is due to wide-spread pumice. Russian expedition teams including Strel'bitskii (Стрельбицкий, 1894, and Garin (Гарин-Михайловский, 1898), also explored this mountain seeking natural resources and territory of East Asia and the Manchurian region in pursuit of Russian Imperial interests explored and described Baekdusan as a volcano.

In this study, we investigated scientists' perception of imagination and explored characteristics of scientific imagination. For this, we found out conceptions and characteristics based on literatures which related to imagination. We recruited eight distinguished Korean scientists who have rich research experiences by using Snowball sampling for in-depth interviews (60-90 minutes). All interviews were audio-recorded and transcribed. From the analysis of interview data, we identified their perceptions of imagination and the nature of scientific imagination which scientists reflect on during their research work. Semi-structured interview protocol was focused on: 1) how scientists perceive 'imagination' and 2) how scientists perceive the role of imagination in their scientific research. As results, we found out that scientists agreed that imagination plays an important role in scientific research process and they perceived imagination as an intrinsic part of human life. The study also indicated that participants have modern viewpoint about imagination. Moreover, we uncovered three characteristics of imagination in the research process. 1) Curiosity and interest have been a driving force for scientists' imagination. 2) When scientists use the imagination, they can be more creative during their research. 3) Imagination contemplated realistic possibilities based on the scientific knowledge, and produced the new ones. Educational implications for utilization of scientific imagination were also suggested.

This study aims to explore the characteristics of translated picture books in South Korea and their cultural meanings over a five-decade period. This time can broadly be divided into three periods, being the Settlement Period (pre-1990), the Flourishing Years (1991-2000) and Globalization (post-2001). During the Settlement Period, picture books in South Korea were derived mainly from Japan and America and tended to be informational in nature or based on folk tales. These were translated into Korean to meet the public's curiosity for foreign cultures or for scientific information. The Flourishing Years were characterised by the availability of picture books on a wide variety on themes and forms from all over the world. In this period, the translation of books into Korean focused on a literal rendition of the meanings and sounds of names from the original text. There was also a proliferation of audiotapes, videos and TV programs based on famous picture books. In the current period of Globalization, Korean publishers, who have built confidence through studying foreign picture books over time, have increased efforts to produce their own picture books and export them abroad.

The purpose of this study was to examine the effects of science-related and scientific attitudes in Small-Scale Science (SSS) experimental learning on 3rd grade middle school students. Two classes were chosen from a middle school in Pohang and classified into two groups: the first group, the experimental group, composed of twenty-six students, undergoing SSS and the other group, comparison group, composed of twenty-five students who were taught experimental learning by the traditional teaching method. The major observations of this study are as follows: The SSS experimental learning significantly influenced the students' science-related and scientific attitudes within the experimental group. Also, there was a meaningful difference in the subcategory of science-related attitudes and scientific attitudes before and after the SSS experimental learning. Otherwise, there was no significant difference in comparison group. In conclusion, the class using the SSS was positively influenced in forming students' science-related and scientific attitudes. In particular, the effect on subcategories of science-related attitudes such as attitude towards science are more remarkable. The SSS experimental learning helps students to enhance the subcategorial factors of scientific attitude such as their curiosity, critical thinking, cooperation, self-participation, persistence and ingenuity. The SSS experimental learning, therefore, can improve learning attitudes.
