  • This study examined the utility of pine (Pinus densiflora) pollen cones as an environmentally friendly material with sound-absorbing properties. Pine pollen cone samples with widths of 0.8-1.2 cm and lengths of 3.5-4.5 cm were prepared. After filling impedance tubes to heights of 6, 8, 10, or 12 cm with the pine pollen cones, the sound absorption coefficient of the pine pollen cones was investigated. The peak sound absorption frequency of the samples with a thickness of 6 cm was reached at 1,512 Hz; however, this value shifted to 740 Hz in samples with a thickness of 12 cm. Therefore, the sound-absorbing performance of pine pollen cones at low frequencies improved as the material thickness increased. According to KS F 3503 (Korean Standards Association), the sound absorption grade of pine pollen cones ranges from 0.3 to 0.5 M, depending on the material thickness of the pine pollen cones. In conclusion, the pine pollen cones demonstrated good sound absorption properties. They, thus, may be considered an environmentally friendly sound-absorbing material.

  • Environment friendly architecture, which will reduce shortcomings of current architectural culture, can be achieved by using natural energy and environment friendly building materials together with their environmental architecture techniques. Particularly, even though the overall building system is perfect, it cannot be considered as comfortable architectural space if the materials are polluted, harmful to human bodies and producing wastes. Therefore, in order to build environment friendly architecture, the selection of the materials is very important and necessary from the planning stage with careful reviews and concern. This study tries to define what the environment friendly materials we, to investigate and to classify them, in order to provide some guidelines for selecting them at plans to build. For examples, the materials can be classified into natural materials, continuously usable materials, recycled materials from wastes, and less polluting materials mixed with natural materials. Finally, this study reviews the existing products in the market and proposes to develop new ones in the future. It will present the circulation of resources in the 21century through recycled and reused materials.

  • This study examined the effects of employees' gender role attitudes, job involvement, and family involvement on their work-family conflicts, work-family facilitation, and utilization of family-friendly corporate policies. Data was collected from 377 full-time married workers from 262 large (more than 300 employees) and 100 small (fewer than 300 employees) private sector companies. The questionnaire's measurements were based on recommendations from the literature review. The questionnaire consisted of the gender role attitude scales, job and family involvement scales, work-family conflict and facilitation scales, and questions pertaining to the employee's utilization of family-friendly corporate policies. The SPSS 12.0 statistical package was used to analyze the collected data. The study found that employees showed more or less egalitarian gender role attitudes and that they were more involved in their family than their job. The employees' responses showed a low rate of utilizing family-friendly policies, but employees from large companies reported a higher utilization of family-friendly policies than those from small companies. There were also gender differences in employees' gender role attitudes, work and family involvement, and utilization of policies. Male workers held more traditional gender role attitudes, had higher levels of job involvement, and had higher rates of utilization of policies than female employees. Meanwhile, employees with children exhibited more traditional gender role attitudes and higher rates of utilization of policies than those without children. Finally, serial hierarchical regression analyses revealed that employees' more egalitarian gender role attitudes and higher job and family involvement predict higher work-family facilitation, while their gender role attitudes and job and family involvement have no significant influence on work-family conflicts. Also, employees from large companies with high job involvement will have significantly higher utilization rates of family-friendly corporate policies.
