The study aims to investigate differences between men and women in influence of various socio-demographic factors on choice of mode of transport. For this purpose, a binary logit model of choice probabilities is implemented on survey data of a developing country city. Results indicate women's choice of travel mode to be more environment-friendly than that of men. Well-educated, working and middle-aged individuals appear to be the most likely to choosing more-polluting modes of transport for frequent travelling purposes. Individuals in the sample who are the least socioeconomically well off are found the most likely to be promising for the environment. The findings of this study suggest the future transportation policies toward development of existing infrastructure of greener modes of transportation in the city such as, public transportation services and pedestrian lanes, so as to manage the rising issues of degrading environmental quality. The study highlights how the consideration and inclusion of socio-demographic factors is crucial for policy recommendation regarding curtailing the environmental damages contributed by transportation sector. Because mobility crucially affects all other indicators of empowerment, and women are the ones using green modes extensively, the city's transportation system should be so developed which gives their safety and security due importance.

A review on the technical development and agricultural policy direction for sustainable agriculture has been made to clarify the present conditions of agricultural environment for food production and natural resource conservation and to study prospects and solutions successfully to achieve food safety and environment conservation as the 21st agricultural paradigm. Although great improvement of environmentally sound and resource-conserving techniques, sustainability of Korean agriculture has been damaged by quantitative reduction and quality deterioration of agricultural land resources, insufficient implementation of low-input and organic matter recycling techniques and also improper cropping system. It is concluded that goal of sustainable agriculture can be successfully achieved by further improvement of environmentally friendly techniques, and stronger escalation of national implementation programmes with more financial supports including direct payments for sustainability of agriculture under systematical support and cooperation of AKS (agricultural knowledge system).

We intend to offer theoretical bases of earth construction technology through the analysis of cases of brickworks and plastering works in the city of Gumi, Kyeongsangbukdo. We search for those instances of earth buildings to confirm the trend that earth construction is recognized as environment-friendly, sustainable and newly spotlighted field to alternatives of building construction. We made a frame of analysis through theoretical consideration about earth construction and prior study. Then, we analyzed the selected buildings which is selected by priority in the city of Gumi as authorized preservation value, cultural assets and recently built modern constructions. We found out some problems in structural strength, durability and fire proofing and the invisible development of technologies of earth construction method in this case analysis.

In a turn a century, the skepticism, mysticism and eroticism used to prevail, the people becoming anxious, expectative and doubtful about an oncoming age. The costumes tend to become more exciting and erotic in the fashion. This thesis is on understanding “What would 21 century's clothes be\ulcorner” after analyzing the specific points in an end of the century. The characteristics found from 16th century to 20th century are going to the extremes in the shapes, consistent appearance of bustle style costumes and excessive ornaments which are closely interrelated with one another. I expect the fashion in 21st century would be changed in two ways. Firstly, going to the extremes and stressing on the buttock would be going down in the end of 1999. Secondly, the comfortable clothes highest in function and technology, and also friendly to the environment, might be the main stream, rather then outwardly good looking clothes, because spirit and environment is much more emphasized than the mode by the social impact or pressure in the next era.

Recently, the construction industry has focused on eco-friendly materials instead of traditional materials due to their harmful effects on the environment. To this end, biopolymers are among proper choices to improve the geotechnical behavior of problematic soils. In the current study, serish biopolymer is introduced as a new binder for the purpose of sand improvement. Serish is a natural polysaccharide extracted from the roots of Eremurus plant, which mainly contains inulins. The effect of serish biopolymer on sand treatment has been investigated through performing unconfined compressive strength (UCS), California bearing ratio (CBR), as well as wind erosion tests. The results demonstrated that serish increased the compressive strength of dune sand in both terms of UCS and CBR. Also, wind erosion resistance of the sand was considerably improved as a result of treatment with serish biopolymer. A microstructural study was also conducted via SEM images; it can be seen that serish coated the sand particles and formed a strong network.

To assess the effects of a proton beam on oyster mushrooms (Pleurotus ostreatus), the genetic diversity and phylogenetic relationships among strains induced by a proton beam were investigated based on a clustering analysis. According to an AFLP DNA polymorphism analysis, the induced strains were divided into four groups that coincided with the dose. When applying proton-beam radiation, the dissimilarity among the induced strains increased when increasing the dose. When using more than 400 Gy, the genetic dissimilarity of the irradiated strains was 46-58%. Thus, evaluating the induced strains using the AFLP technique was effective in revealing the mutation effect of the proton beam.
