직장 내 성차별은 많은 나라에서 아직도 큰 사회적 이슈이고 전 세계적으로 국제기관과 각국 정 부들은 이를 줄이기 위해 많은 노력을 기울이고 있다. 기업들 또한 직장 내 성차별을 줄이는 것을 사회적 책임 활동의 하나로 여기고 점차 많은 관심을 보이고 있다. 이러한 추세를 바탕으로 본 연 구는 외국인 소유가 직장 내 여성차별에 어떠한 영향을 미치는지를 조사한다. 한국직업능력개발원 에서 구축한 인적자본 기업패널 자료를 분석하여 본 연구는 외국인이 소유권을 보유하고 있는 회사 는 한국인만이 소유권을 보유하고 있는 회사에 비해 좀 더 많은 여성 인력을 채용하고 있음을 밝혔 다. 또한 외국인이 소유권을 보유하고 있는 회사는 상장회사일 경우 비상장회사에 비해 정규직 여 성채용에 더 적극적임을 발견했다. 이러한 연구결과는 외국인 투자가 현지국의 직장 내 성차별이라 는 사회적 이슈에 미치는 영향을 보여줌으로 외국인 투자와 성차별에 관한 연구분야에 유용한 시사 점을 제공하고 있다.

This study aims to identify the effect of home physical therapy on patients who left the hospital after total knee arthroplasty, compared to the Daily living group, when it was applied to them, under the guidance of physical therapists. As research subjects, 20 patients that were scheduled to leave the hospital after unilateral total knee arthroplasty, were chosen, and they were randomly divided into a home physical therapy group(10 patients) and an Daily living group(10 patients) in order to conduct an experiment. During the 4-week research, home physical therapy was offered for 40 mins once for 5 days a week, and muscular strength, gait components were measured. For muscular strength, quadriceps muscle strength, hamstring muscle strength were measured, and as gait components, endurance, speed, step time, single-limb support were analysed. For this experiment, pre- and post-measurement were performed, and collected data were analyzed using SPSS ver. 18.0 statistical program. From the analysis of data, the following study results were obtained. Home physical therapy group and Daily living group both showed significant improvements in quadriceps muscle strength, hamstring muscle strength, and quadriceps muscle strength, hamstring muscle strength of home physical therapy group more significantly improved than Daily living group's. In relation to gait components, gait endurance, gait speed, step time significantly improved in both of home physical therapy group and Daily living group, whereas home physical therapy group only showed significant improvements in single-limp support. According to the comparison between two groups, gait speed, single-limp support and step time improved more significantly in the home physical therapy group than in the Daily living group. In conclusion, positive results were revealed in both home physical therapy group and Daily living group, with regard to muscular recovery of lower limbs of patients discharged from the hospital after total knee arthroplasty and walking, but considering the comparison results between two groups, it seems that applying home physical therapy is more effective than maintaining a daily life.

Plant biomass is a huge carbon-complex that has potential as a nutrient. Therefore we extracted and separated useful materials for plant growth from tea leaf and stem. The pre-treatment process including high temperature (200 °C) and pressure (20-40 kgf/cm2) was treated for several minutes and extracted at 120 °C for 30-60 minutes. After that the chemical compositions and ingredients were analyzed from that plantnutrient. As a result of mineral contents, calcium and magnesium concentrations are higher than other minerals. Also the result of carbohydrates analyses has shown that the sugar oligomer consists of xylose(95.3%) and glucose(4.7%), and the sugar monomer consists in the order of xylose (52.7%) > manose (22.8%) > arabinose (10.8%) > galactose (10.2%) > glucose (3.5%). Before applied to field, in vitro plant growth system and formulation were examined. To evaluate the effect of the nutrients, both strawberry green-house and persimmon fields were used in this test. The treated persimmons were heavier than controls scored at 13-22%. In addition, the storageperiod was extended in the treated strawberries. Interestingly in the treated strawberry, the contents of polyphenols were increased (38-57%). These results suggest that the plant-nutrient can afford to help for plant growth and storage, and it can be substituted for other commercial nutrients. In conclusion, this plant-nutrient may help to extend eco-friendly or organic farming in Hadong-gun area.
