The purpose of this study is to examine an influence of university students' openness to diversity on career preparation behavior, unlearning, and the mediating effect of unlearning. The survey questionnaire was distributed to 258 university students and SPSS 22.O program was used for statistical analysis of the data. The results of this study are as follows: First, openness to diversity has a positive effect on career preparation behavior and unlearning. Second, unlearning also has a positive effect on career preparation behavior. Third, unlearning has a partial mediating effect between openness to diversity and career preparation behavior. These results show that the more students enhance their openness to diversity and unlearning, the more students develop their career preparation behavior.

The current enforcement regulation of "The Act on the Promotion of Construction Waste Recycling" defines disposal method of combustible construction waste without obvious recyclging method of those. This leads most combustible construction waste to incinerate or landfill as mixed construction waste. Therefore, it needs regulations to decrease incineration or landfill and to increase recyling of combustible construction waste. This study analyzed the problems of disposal and management of domestic combustible construction waste. As well as considerated regulations relative to utilization of waste solid fuel. From these results, it suggested utilization plans of combustible construction waste as fuel.

The purpose of this study is to propose the efficient and reasonable weeding model of the scientific literature by measuring a life-span of literatures in the field of nuclear engineering through citation analysis, the average life of actually discarded literatures in the KAERI (Korea Atomic Energy Research Institute), and the life of use through the circulation data analysis from 1992 to 1994 of KAERI.

Public Libraries in Seoul have been steadily increasing their numbers from 4 libraries in 2004 to 15 libraries in 2009. On the contrary, the size of recently established public libraries have been reduced compared to the previous ones. Because of their limited space, which cannot manage increasing collection, public libraries started collection disposal. This research investigated public libraries' disposal standards and present conditions of collection items. Based on this investigation, enhance way of the collection disposal was suggested.

Chemical compositions such as total sugar, sulfate/total sugar, protein and 3,6-anhydrogalactose content of porphyran extracted from commercial laver, discolored laver and laver waste were measured. The total sugar contents of commercial laver, discolored laver and laver waste showed 54.5%, 45.7% and 56.2%, respectively. The total sugar of the commercial laver and laver waste were showed almost similar portion although that of discolored laver showed relatively lower level. The sulfate/total sugar contents showed 17.6%, 13.9% and 17.3%, and 3,6-anhydrogalactose contents showed 13.8%, 9.1% and 13.9% in commercial laver, discoloredlaver and laver waste respectively.

Background : The diagnosis of emphysema during life is based on a combination of clinical, functional, and radiographic findings, but this combination is relatively insensitive and nonspecific. The development of rapid, high-resolution third and fourth generation CT scanners has enabled us to resolve pulmonary parenchymal abnormalities with great precision. We compared the chest HRCT findings to the pulmonary function test and arterial blood gas analysis in pulmonary emphysema patients to test the ability of HRCT to quantify the degree of pulmonary emphysema. Methods : From october 1994 to october 1995, the study group consisted of 20 subjects in whom HRCT of the thorax and pulmonary function studies had been obtained at St. Mary's hospital. The analysis was from scans at preselected anatomic levels and incorporated both lungs. On each HRCT slice the lung parenchyma was assessed for two aspects of emphysema: severity and extent. The five levels were graded and scored separately for the left and right lung giving a total of 10 lung fields. A combination of severity and extent gave the degree of emphysema. We compared the HRCT quantitation of emphysema, pulmonary function tests, ABGA, CBC, and patients characteristics(age, sex, height, weight, smoking amounts etc.) in 20 patients. Results : 1) There was a significant inverse correlation between HRCT scores for emphysema and percentage predicted values of DLco(r = -0.68, p < 0.05), DLco/VA(r = -0.49, p < 0.05), FEV1(r = -0.53, p < 0.05), and FVC(r = -0.47, p < 0.05). 2) There was a significant correlation between the HRCT scores and percentage predicted values of TLC(r = 0.50, p < 0.05), RV(r = 0.64, p < 0.05). 3) There was a significant inverse correlation between the HRCT scores and PaO2(r = -0.48, p < 0.05) and significant correlation with D(A-a)O2(r = -0.48, p < 0.05) but no significant correlation between the HRCT scores and PaCO2. 4) There was no significant correlation between the HRCT scores and age, sex, height, weight, smoking amounts in patients, hemoglobin, hematocrit, and wbc counts. Conclusion : High-Resolution CT provides a useful method for early detection and quantitating emphysema in life and correlates significantly with pulmonary function tests and arterial blood gas analysis.

This study was conducted with pot experiment to find out the effect of ginkgo leaf wastes application produced from the pharmaceutical process on the growth and yield of red pepper. Four kinds of ginkgo leaf wastes, the natural dried leaves, the leaves produced from the pharmaceutical process, the dried leaves to remove methanol after the pharmaceutical process, and the leaves washed with water to removal methanol and some activated materials after pharmaceutical process, were treated with two levels of application rates. The growth responses and yield were measured throughout the experimented period. Shoot growth of red pepper was inhibited by all treatment of ginkgo leaf wastes compared to the treatment of NPK and NPK+compost. Red pepper yields were also significantly reduced by treatment of the ginkgo leaf wastes except for the treatment of the water washed ginkgo leaf wastes, 1,000 kg/10a, which showed similar yield to NPK treatment. The major reseon to reduce the growth and yield seemed to be originated from the allelopathic substances of the ginkgo leaves. The organic matter contents of the soil after experiment were slightly increased with the treatment of the ginkgo leaf wastes and compost than that of NPK treatment. Based on these results, this study for using the ginkgo leaf wastes should be done more to utilize the wastes of the pharmaceutical process as a organic fertilizer.

제품 생산자가 폐기물 수거 책임을 위해 수거비를 정부에 지불하는 경우와 자체적으로 정부 인정하에 수거 폐기하는 경우가 있는 것으로 분류되고 있다. 2001년 국내 굴지 5대 음료회사에서 정부와 합의한 것 중 하나가 자체 생산제품의 폐기처분 비율을 정부에 지불하지 않는 대신에 자체적으로 폐기하도록 합의하였다.(중략)
