  • The effectiveness of rehabilitation programs for coal mining spoils in Samcheok, Jeongsun, and Mungyung were evaluated based on the physicochemical properties of soil in the rehabilitated areas. These spoils were reclaimed by introducing plants such as black locust (Robinia pseudoacacia), pitch pine (Pinus rigida), birch (Betula platyphylla var. japonica), alder (Alnus hirsuta), bush clover (Lespedeza cyrtobotrya), and grass (Lolium perenne) in planting beds covered with forest soil. In the surface soil, the pH, organic matter, total N, available P, and exchangeable Ca showed significant changes over the years after reclamation. The pH and exchangeable Ca content decreased exponentially over time, whereas organic matter increased linearly and total N and available P increased exponentially. Changes in the physicochemical properties of subsurface soils displayed a different pattern. There were significant changes over time in the organic matter, available P, and exchangeable Ca and Mg contents of the soil. Organic matter increased logarithmically with years since rehabilitation and available P increased exponentially. Meanwhile, exchangeable Ca decreased exponentially, and Mg decreased logarithmically. The changes in the subsurface soil were not as dramatic as those in the surface soil. This result suggests that the ameliorating effects of the establishment and growth of plants more pronounced on the surface soil layer. Stand ordination data showed different relationships with time since rehabilitation in the early and later stages of the rehabilitation process. In the early stages of rehabilitation, stands tended to be arranged in the order of reclamation age. However, in the later stages, there was not a clear relationship between reclamation age and vegetation characteristics. This result suggests that soil amelioration is required for the early stages, after which an autogenic effect becomes more prominent as the vegetation becomes better established.

  • The purpose of this study was to investigate the relationship between working environment and quality of life of fashion vendor company workers by using working environment variables such as job stress, job burnout, job satisfaction, and turnover intention. Preliminary test was conducted by interviewing fashion vendor company workers in order to find out factors that were more suitable for their working environment. Main survey was conducted to 200 fashion vendor company workers and 194 responses were analyzed. The results of correlation analysis showed that job stress, job burnout, job satisfaction, turnover intention, and factors of quality of life had significant relationships. Boss stress, role stress, achivement decrease, and personal condition satisfaction showed a significant relationship with turnover intention. The results of path analysis showed that job stress had a positive relationship with job burnout and job burnout had a negative relationship with job satisfaction. Both job stress and job burnout had a positive relationship with turnover intention, whereas job satisfaction had a negative relationship with turnover intention. Also, the results showed that job burnout and turnover intention had a negative relationship with quality of life of fashion vendor company workers, whereas job satisfaction had a positive relationship with quality of life of fashion vendor company workers.

  • 1) Table salt (=NaCl=common salt=salt) is scientifically characterized, and the significant role in dietary and daily life has generally been discussed from the standpoint of human ecology. 2) In dietary life, salt fundamentally gives a deliciousness to dishes and nutro-physiologically functions to keep homeostasis in the body. Meanwhile, the excessive intake of salt often causes the high blood pressure and induces several fatal diseases. 3) In daily life, salt derivatives(Na-, Cl-compound) are quite useful widely over food, clothing and housing. Meanwhile, some of them especially organochlorine compounds often pollute the environment and damage the humans and or ecology as so-called environmental hormone resulting in dioxins. 4) For the ambivalence of salt in health and environment, humans, but not salt, are wholly responsible. The fact would go not only to salt but also generally to resources on the earth. 5) Humans should adequately be moderate in utilizations and consumptions of salt and or resources. Everything must be kept with in bounds. This conception would surely bring the stable maintenance and the sound development to the system of human ecology as well as global ecology.

  • The object that we have researched the design for a long life of product is to search for the method to cope with the various environment problems where our mankind is confronting in the field of Production Design. The environment problem on earth is affecting seriously the enterprise which produces the product, the user who consumes it and even the field of product design. Now we live our daily life with a lot of artifacts while the citification and modernization have been progressing around us. Especially, 20 century was the times of the highly advanced scientific civilization and industrialization. Therefore it affected decisively our life environment base nowadays. The result was that our human life became rich because of the advanced development of industry, productivity and distribution structure. On the other side, the industrial system in the period of these massive production and massive consuming is bearing various problems proportionally. Those are the depletion of resources and energy, earth environmental pollution and various kinds of waste. In addition, the material which cannot recycle is appearing at the large quantity. This is the actuality of now. Our subject is how product design will cope with it as counter measures and the subject is very important to our mankind and earth environment.

  • Since the Rio Convention of 1992, the international community has displayed a heightened consciousness concerning the Earth environment and domestic attention on the said subject has also rapidly increased. An Ecological life style signifies the conscious efforts to preserve the environment interpreted into quotidien action. For the realization of conservation in action, an understanding of the specific details of environmental preservation must precede. The environmental conservation action in the homes was systematically approached in this study as an input-process-output and feedback cycle. The input phage is the consumer oriented buying stage, the while the process is the actual use of the products and the output stage consists of categorizing and producing wales, the feodbach being recycling of resources. At each stage the attitude which is devoted to environmental consciousness plays a big ride in the actual preservation of the Earth environment. in order to effectively conserve the environment, efforts displayed by the business sector is as important as implementation of environmentally conscious action at home. During the process of producing and distributing products, and attitude and action in preservation efforts are crncial and the responsibility ageat. For the business sector to effectively initiate environmental preservation into action, institutional support from the government and cooperation from the homes is of essence. Consolidated efforts to atter the superfrony life style into ecological life styles and ralues is essential to solve the most important socio-economic issue of the 90's of preserving the earth.

  • Pleurotus eryngii is one of the most commercially important mushrooms cultivated in Korea. However, the shelf-life of the fruiting body is short, limiting its export. A new hybrid strain H17 of P. eryngii was developed to extend the shelf-life by mono-mono crossing between monokaryotic strains derived from DanBi and KNR2774. Although the cultivation period of H17 was slightly longer than that of the reference cultivar Kenneutari No.2, the quality did not change and remained normal after a period of 65.0 days at $4^{\circ}C$. This result was significantly different from that of the reference cultivar Kenneutari No.2. Analysis of the genetic characteristics of the new hybrid strain H17 revealed a different profile from that of the parental and reference cultivars when random amplification of polymorphic DNA (RAPD) primers was used. These results demonstrate that H17 is a new cultivar with improved storability after harvesting.
