This project aims to provide information on organizations and characteristics of Korean designer fashion industry in order to improve employment environment in fashion designer brands. This study utilizes the questionnaires and interviews with designers or human resources managers in Korean designer brands for forms, size and way of employment. The result shows that firstly, the size of employment in fashion designer brands is almost operated by small-scale human resources. Secondly, It is researched that they recruit less than 10 temporary employees per a brand on average as a problem. Thirdly, there are differences in business according to forms of employment. As researched, permanent employees usually conduct in design, products plan and production management, but, temporary employees conduct as a business assistant and salespeople. Fourthly, it is revealed that average salaries for permanents in fashion designer brands are between 1,510,000 and 2,000,000 won as the most people said. Moreover, the average salaries for temporaries are similar with permanents’ as between 1,170,000 and 1,500,000 won. In fifth, in terms of the ways for recruitment, the proportion of job seekers who find a job by nonscheduled admission and special employment is larger than other ways. Finally, as a result of a research on an employment contract, employees have written the employment contract with the brands.
서남극 사우스셰틀랜드 킹조지섬 바톤반도 육상 토양의 광물학적, 지화학적 특성

남극의 토양 환경에 대한 기초자료를 확보하기 위하여 킹조지섬 바톤반도에 위치한 세종기지 주변지역의 토양 성분과 토양을 구성하는 점토광물의 종류 및 분포, 조성을 규명하고자 X선 회절분석과 습식분석(철의 산화도와 양이온 교환능 측정), 투과전자현미경-전자에너지 손실 분광분석, 전함량 분석을 실시하였다. X선 회절 분석을 실시한 결과, 스멕타이트, 일라이트, 카올리나이트, 녹니석이 주요 점토광물로 함유되어 있으며 석영, 사장석 등의 화산활동 기원 초생광물도 함께 수반되어 나타났다. 토양 시료의 철 산화도 분포는 대부분의 지점에서 Fe(II)이 20~40%, Fe(III)이 50% 이상 토양 입자상에 존재하였고, 나노 스케일에서 스멕타이트를 분석했을 때 광물 구조 내 Fe(III)/ΣFe이 약 57%로 분석되어 전체 토양의 철 산화도와 유사한 결과를 보였다. 양이온 교환능은 전반적으로 100-300meq/kg 범위였으며, 시료 채취지점에 따른 유의미한 차이는 보이지 않았다. 전체 토양의 전함량 분석결과, 광물의 주 구성 원소(Mg, K, Na, Al, Fe)는 지점에 따른 차이를 보이고 있는 반면, 중금속 원소(Co, Ni, Cu, Zn, Mn)는 지점별로 유사하게 나타났다. 이러한 결과들은 토양을 구성하는 기반암이 기본 원소 분포에 영향을 줄 수 있음을 보여준다. 따라서 본 연구 결과는 남극 지표 토양환경과 토양 내 점토광물에 대한 기초자료 확보에 있어서 많은 도움이 될 것으로 기대된다. Surface soils on Barton Peninsula, King George Island, West Antarctica were investigated to acquire the mineralogical and geochemical data of soil in Antarctica. Multiline of techniques for example, X-ray diffraction (XRD), transmission electron microscopy (TEM)-electron energy loss spectroscopy (EELS), and wet chemistry analysis were performed to measure the composition of clay minerals, Fe-oxidation states, cation exchange capacity, and total cation concentration. Various minerals in sediments such as smectite, illite, chlorite, kaolinite, quartz and plagioclase were identified by XRD. Fe-oxidation states of bulk soils showed 20-40% of Fe(II) which would be ascribed to the reduction of Fe in clays as well as Fe-bearing minerals. Moreover, redox states of Fe in smectite structure was a ~57% of Fe(III) consistent to the values for the bulk soils. The cation exchange capacity of bulk soils ranged from 100 to 300 meq/kg and differences were not significantly measured for the sampling locations. Total cations (Mg, K, Na, Al, Fe) of bulk soils varies, contrast to the heavy metals (Co, Ni, Cu, Zn, Mn). These results suggested that composition of bed rocks influenced the distribution of elements in soil environments and soils containing clay compositions may went through the bio/geochemical alteration.
