Science field trip on historical heritages in Korea has developed since 1998. There are a few discussion of effectiveness of science field trip on historical heritages. In this research, the aim of science field trip on historical heritages was discussed in view of developing scientific perspectives on historical heritages with cases of science field trip of Hwasong fortress. Material for science field trip of Hwasong fortress was developed and instructional strategy was designed. The material contained convergent and divergent scientific inquiry activities. The goal of the activity was to help students to build scientific perspectives on the historical heritage, so they can evaluate the scientific excellency of historical heritage. The subjects were ten ninth grade students of middle school science club in Seoul. A questionnaire, "evaluation of scientific excellency of historical heritage" was administered before and after the field trip. From the analysis of a change in perspective by field trip, it was investigated how the scientific perspective on historical heritages was developed. The first draft of material for science field trip of Hwasong fortress was developed based on science education experts' discussion. The material has three parts; activities before the trip, activities during the trip and activities after trip. Instructor's guide has the same structure. Before the field trip, students watched the videotape and learned the short history lesson about Hwasong fortress to develop familiarity. During the trip, there were exploring stage and intensive inquiring stage. These activities were designed to develop scientific perspective on historical heritage. After the field trip, evaluation activity about scientific value of Hwasong was done based on the activities done during the trip. After the science field trip of Hwasong fortress, most of students showed positive changes. Some of them reflected on their previous thoughts. Some recognized the necessity of the proper criteria for scientific excellency of historical heritage. All changed in their perspective on evaluating scientific aspects on historical heritage, such as considering the social environment, scientific principles and the influence of science and technology of that age on the society, when the fortress was built. These results show that the science field trip focused on the criteria for evaluating the scientific excellency of historical heritage was significant in helping students to develop the scientific perspective on historical heritage.

This study analyzes the effect of demographic changes on economic growth. We use the supply-side output identity to forecast the growth potential of the Korean economy. According to the results, even based on optimistic assumptions and prospects, the economic growth rate is likely to fall drastically starting in 2020. Of course, to maintain growth potential, efforts to increase productivity are necessary. However, given the historical experience of developed countries, it is not clear whether the huge trend of demographic change can be offset by efforts to increase productivity. In the so-called '30-50 club' countries, both labor productivity and growth rate tend to fall after reaching the per capita income of $30,000. The degree of decline in the growth rate is closely related to changes in the working age population and the prime-age workforce. The results are similar when tracking the path of changes in total factor productivities of the economy. When a certain level of income is reached, the increase in total factor productivity also tends to slow down. The ripple effects of rapid changes in demographics will indeed be extensive. The negative impact is likely to be concentrated at a time when the working age population, the prime-age workforce, and the total population shrink simultaneously. Above all, it is necessary to use the government's fiscal space to block the possibility of a rapid fall in the growth rate. In addition, it is important to continuously implement various reform tasks that should be promoted, such as improving the education system and strengthening the social safety net.

Second, reused resources and remodeling of existing building. Third, Sustaiabl design component and management process. Historic resource are not only a cultural and spatial aspects but also it have potential importance in environmental aspects. Sustainable urbanism and architectural environment are cultural resource and it can be enhanced by long term established spatial orders.

This paper explores the upper and lower contexts of the literature, and examines the meaning that the context intends to say and the era indicated by '古'. This not only helps to objectively and concretely recognize and interpret the "old" era, it can also be used to dig deeper into the meaning of the literature. In particular, such research is expected to play an even greater role in the literature that needs to clarify historical facts. '古' can be specified differently depending on the literature. In this paper, in particular, focusing on this point, in order to examine more closely how the periodic interpretation of '古' was done, the interpretation and usage examples of '古' were intensively examined. Notable items in the meaning of '古' are the meanings of beginning, ancestor, always, forever, and so on. In particular, in historical literature, the first beginning of civilization was viewed as 'old'. It is emphasized that the age of pay wages is viewed as the "old" at the base point.

We collected age determination cases which were done at Yonsei university dental hospital, department of oral medicine from 1976 to 1999 to analyze it's tendency among Koreans. We analyzed 435 clients cases which were stored by age estimation program from January 1993 to December 1999. The results are as follows: 1. There were no significant difference in the sexual distribution (male : 52.0%, female : 48.0%) and more than half percent (51%) were 20's and 30's. 2. Among the age determination clients, those who wanted to decrease their age (50.3%) and those who wanted to increase their age (49.7%) shows similar in number. And the former case were predominant in the female clients, but the latter case in the male clients. Also the clients below six years of age were predominant in the former case, but the clients more than sixty were predominant in the latter case. 3. The purposes of age correction showed different distribution for ages: job or employment for 20's and 30's, marriage for 20's, registration for school for below six, welfare and other social services for 50 and older. 4. Age was estimated by Nolla's growth stage for 12 and under, calcification of the second and third molar for 12~20, and for 20 and over, Takei's tooth abrasion model was used. 5. The alleged age was in accordance with the documents and other information given by clients, but in the 20.6% of the estimation cases, the alleged age was discarded. In the results of the analysis of age determination cases in Koreans, many of the cases resulted from our historical turbulence and social distinctiveness, causing an increase in the necessity for age correction in each age group. For more accurate determination for each age group, further studies with Koreans must be done continuously.

The white color is the main characteristics of the traditional color of clothes. From the historical point of view, the Korean's pattern of wearing Baik-Eui can be found its origin from many people of North-East Asia in ancient time. The beginning of wearing Baik-Eui in Korea was at the age of tribes, and it was delivered to middle age, later on, to modern age near the end of Yi Dynasty. The other charactics of the traditional colors. are summarized as follows: 1. Prefered light color to dark color and light blue was noble and worthy. 2. The kinds of color were not various. 3. Color was native and pure not including grey or other colors. From the economical point of vie, the first thing is that Baik Eui was primitive in ti's color Though some say that wearing Baik-Eui is considered as a kind of worship of the Sun, yet we can also find that the every reason of it is that we had little dyes at that time. Especially the reddish dyeing materials were in short supply, so that had been imported mainly from Japan.
