This study examined the illustrations in the elementary school textbooks which was followed by identifying the parts that displayed gender-discriminating elements or traditional gender roles. The research results are as follows: 1) The ratio of man and woman in the figures appearing in those illustrations was 1.33:1, which means there were more men than women in the illustrations and that there was no balance in the gender distribution among the figures. 2) Male figures were presented as the protagonists in 39.7% of the illustrations, female figures in 25.5%, and both male and female figures in 34.8%. The results indicate that there were much more illustrations in which men were the protagonists than those in which women were. 3) The occupations of the adults in the illustrations were analyzed. As a result, the ratio of man and woman with a job was about 2:1, which implies that there were twice as many male professionals than female ones. Men had over 60 kinds of occupations and women had only 45 kinds of occupations with 59.5% of them concentrated in four jobs including teaching, farming and fishing, doing artistic works, and selling things. 4) The case analysis results of the illustrations in the textbooks demonstrate that the traditional gender roles of a father and mother were followed and that there were gender stereotypes in describing the characteristics of man and woman. Gender dichotomy was observed in the vocations. Men were the leading players in economic, political, and cultural activities, and most of the historical figures were men. Meanwhile, women were depicted as the subjects of economic activities and completely isolated and alienated from political, historical, and cultural activities. It turned out that the figures of the illustrations in the current elementary school textbooks had gender discriminating elements and profoundly reflected the stereotypes for gender roles.

Wild ginseng production is increasing due to forest recovery for last 30 years. Total number of Symmani (traditional mountain ginseng digger) was 558 in 2001. Provincial distribution of Symmani in 2001 was highest in Kangwon $(32\%),$ next in Choongbook $(21\%)$ and least in Jeonnam $(0.7\%)$ and Kyoungnam $(0.9\%).$ Age distribution of Symmani was $33\%\;for\;fourties,\;32\%$ for fifties and $20\%$ for sixties. There were 8 persons in eighties. Symmanies are still keeping traditional ritual for mountain god serving clothes of colored ribbons and foods. Increased production induced open market system from underground dealing of mountain ginseng. Korea Mountain Ginseng Association established mountain ginseng assessment committee with professional Symmanies in 2001. From September to November in 2001, 987 roots were requested for quality assessment to the committee and 476 roots $(48\%)$ were passed and graded and others were rejected. Highest frequency of rejection was foreign origin. Pass rate was highest $(74\%)$ in Choongnam suggesting best place for quality. Number of collected roots in each province was positively correlated (p=0.05) with number of Symmanies. There are 3 quality groups of mountain ginseng, Heaven (pure natural), Earth (from seeding of wild ginseng) and Man (from seeding or seedling of wild ginseng with slight environmental modification). The relationship between price and age was polynomial in high quality root, Heaven, Earth and seed long head of Man group, and linear in low quality group, seedling long head of Man. The best one in 2001 was 26 g, 124 years old and sold with 109 million won. Quality criteria are age, shape, weight, color and healthy outlook. Fine roots are criteria for health status of roots and taproot is criteria for efficacy and called as medicine barrel. The implication is that ginsenosides have rarely been experienced for efficacy. The quality criteria of cultivated ginseng were originated from those of mountain ginseng. It is unique for mountain ginseng that only fresh one can be on market. Since quality criteria of mountain ginseng must be based on the efficacy experience it is well expected that present criteria might almost be established at the age of Shinnong Materia Medica.

One of the characteristics of the last four decades after 'World War II', was the 'discovery of famine' in the underdeveloped country, like Korea. A flurry of activities followed this sad discovery. Countless organizations and programs were set up to fight poverty and to combat famine in rural sector. In these days, the dominant development theory was 'modernization theory' which have gratuitously assumed that third world countries are like western countries are, and respond to the same stimuli as western countries do, although third world countries have completely different cultures, traditions, and mentality from western countries. Among the many problems caused by 'modernization theory', this research focused on the noel environmental problems. In the West the discovery of nature and its progressive control by means of science and technology are phenomena. Modem progress born in the West and carried to the rest of the world is not integrally positive and therefore can't be identified with the internal development of man and nature. As a result, the so-called modernization of Korea and other countries is contributing to the degradation of the nature and environment. It is important to give up the illusion that the fight against famine is a simple matter that could be solved through the imitation of western countries. It is also necessary to abandon the belief that the earth as a reservoir of unlimited resources, there to be exploited ad hoc for mankind's survival. Man-environment relationship must, essentially, be one of mutualism and not a case of survival of the fittest: In other words, man's survival is directly related to the survival of the earth and its resources.

Of the classical theories on lateral earth pressure, the Coulomb's and the Rankine's theories, which have been usually used in practice for design of retaining walls, assumed that the lateral earth pressure was a triangular distribution. However, the experimental results obtained by Terzaghi(1934), Tsagreli(1967), Fang & Ishibashi(1986), etc showed that lateral pressure were not triangular distribution. ' In this study, for rigid walls with inclined backfaces and inclined surfaces backfilled by $C-\phi$ soils, an analytical method of earth pressure distribution has been newly suggested by using the concept of the flat arch. The results calculated by the newly suggested equations were compared with ones by the existed theories. And'the influence factors of the earth pressures by the suggested equations were investigated. As a result, the thrusts obtained by this method agree well with those by the existing theories, except the Rankine's solution. It was showed that the height to the centre of pressure(h) depends mainly upon the inclinations of the backface and the backfilled surface, the angle of internal friction, and the adhesion between the wall and the backfilled soil, instead of 0.33H, where H is the wall height.

The progress of environmental science and technology in the developed countries has been rapid in recent years. Particularly remarkable has been the advancement of various pollutant control measures, which have brought the pollution of inorganic factors such as air and water under control. In contrast, diversity of the ecosphere, of which man is a part, is being steadily impoverished and the biological community is getting unvaryingly uniform. These phenomena were brought about by the expansion of artificial environment such as new industrial complexes, transportation facilities and urban development. Man has constructed uniform and artificial environment, believing in the premise of confrontation with nature, to such a scale that the natural environment and biological community have lost their balance. This will increasingly endanger the soundness of the biotic environment of nature, which constitutes the potential foundation both for the survival environment of man as biological entity and for the development of human civilization. In order to guarantee the soundness of man's body, intelligence and sensitivity as wholesome gene pool on the earth and for the future of man, primarily important environmental education is the understanding of how man can everlasting exist in and with the survival environment. In view of this reality, it is vitally important to create ecologically diverse and well-balanced environment with living materials, i.e., vegetation in order to secure lasting survival environment for man. This task is urgently required in highly artificial environment where non-biological materials have forced the impoverishment of the biological community. Therefore, environmental education for the future should not be totally oriented to technology as that in the past nor it is limited to the medical aspect where well-being of human is the sole object of concern. That is to say, environmental education for the future should be one that provides knowledge that human can understand his place based on the ecological concept and thereby make him to have ethical consciousness that he can control his behavior within the reasonable level for ecological niche who he is located.

The performance of innovative prestressed support (IPS) earth retention system applied in soft clay was investigated and presented. The IPS wale system provides a high flexural stiffness to resist the bending by lateral earth pressure, and transfers lateral earth pressure to strut supports. The IPS wale system provides a larger spacing of support than conventional braced and anchored systems. The IPS earth retention system was selected for temporary earth support in a building construction in North Busan area. The excavation was made 28.8 m wide, 52.0 m long, and 16.1 m deep through loose fill to soft clay. The IPS system consists of 650 mm thick slurry walls, and five levels of IPS wales and struts. Field monitoring data were collected including wall deflections at six locations, ground water levels at four locations, IPS wale deflections at thirty locations, and axial loads on struts at twenty locations, during construction. The IPS earth retention system applied in soft clay performed successfully within a designed criterion. Field measurements were compared with design assumptions of the IPS earth retention system. The applicability and stability of the IPS earth retention system in soft clay were investigated and evaluated.

Even though a systematic sampling approach is very crucial in both the general and detailed investigation phases to produce the best conceptual site model for contaminated sites, the concept is not yet established in South Korea. The U.S. Environmental Protection Agency (EPA) issued the 'Strategic Sampling Approaches Technical guide' in 2018 to help environmental professionals choose which sampling approaches may be needed and most effective for given site conditions. The EPA guide broadly defines strategic sampling as the application of focused data collection across targeted areas of the conceptual site model (CSM) to provide the appropriate amount and type of information needed for decision-making. These strategic sampling approaches can prevent the essential data from missing, minimize the uncertainty of projects and secure the data which are necessary for the important site-decisions. Furthermore, these provide collaborative data sets through the life cycle phases of projects, which can generate more positive proofs on the site-decisions. The strategic sampling approaches can be divided by site conditions. This technical guide categorized it into eight conditions; High-resolution site characterization in unconsolidated environments, High-resolution site characterization in fractured sedimentary rock environments, Incremental sampling, Contaminant source definition, Passive groundwater sampling, Passive sampling for surface water and sediment, Groundwater to surface water interaction, and Vapor intrusion. This commentary paper introduces specific sampling methods based on site conditions when the strategic sampling approaches are applied.

To research the cause of the low and the poor visibility phenomena of Kimhae international airpot statistically, we analyzed the field routine data for the last five years from 1985 to 1989. The poor visibilities below 1km, 3km, and 5km usually occurred at about 6 o'clock in the morning under the condition of calm or light wind from south to southwest direction, and lasted for from 1 to 3 hours. they were caused by the radiative cooling and the inflow of moisture from the South Sea. The frequency of th low visibility(below 9km) recorded 48.1% a year. And the low visibility below 8km with relative humidity below 70% often occurred in the case of southeast, southwest, and northwest wind. And it reveals a peak at 11:00 a.m.. It is supposed to be caused by the pollutants flowing from the neighbouring industrila complex, Sasang, Jangnim and by the photochemical reaction. And, when the industrial direction from Kimhae international airport, the visibility and the air pollution may become worse and worse by the increased pollutants.

The environment and the ecologic balance of the earth had been destructed by both man and ecological catastrophes and are no longer sustainable. We have no future unless we conserve our natural resourses and make efforts to change our basic patterns of consuming, production and recycling. Our earth had been contaminated without our recognition. We became indifferent to environmental problems and even more we hve lost our interest completely. To overcome this period of crisis, the concept of 'green imperative'has emerged. Since design powerfully influences our lives and the environment for good or ill, those at the forefront of design to consumers and the end-users can contribute to the well-being of the people and planet through new awareness of environmental and ecological based design. The spiritual awareness of green design will enrich the work of design through lasting performance of continuty and will make the future work.
