Population aging and longevity have compelled major worldwide consumer markets to focus on senior citizens who exhibit a desire to nurture their appearance and obtain related products such as cosmetics. This trend signals an increasing need for in-depth research on elderly consumers in the color cosmetics market. This study identified the characteristics of seniors in the pre-elderly stage ("new seniors") based on their lifestyle and market segments. It employed online surveys with participants consisting of pre-elderly Korean women born between 1955 and 1963 who reside in the greater Seoul and Gyeonggi area. The study used SPSS 23.0 for factor analysis, reliability verification, cluster analysis, ANOVA, Duncan's test, and cross-analysis. The results show that new seniors could be classified into four groups based on lifestyle: Prime Seniors, Potential Seniors, Rational Seniors, and Slump Seniors. Each group has distinct characteristics. The findings suggest that the senior market requires further segmentation and is no longer a single uniform market. This study also confirms that the lifestyles of the elderly is an instrumental variable for their segmentation.

The purpose of this study is to investigate the level of role stress perceived by employed housewives working in sales departments, and further, to devise coping strategies that can help reduce stress resulting from their multiple roles The sample of this study consisted of married women who were working in sales departments, who have at least one child, and who live in the greater Seoul metropolitan area. A total of 343 out of 450 originally distributed questionnaires were used for the analysis in this study. The findings of the study are: 1 The housewives in sales departments felt stress most severely in their role as a mother. Next were the roles as a wife, housewife, daughter, daughter-in-law, and working woman, in that order. 2. It appeared that age and the motive for employment affected the overall level of role stress among housewives. The two variables (age and the motive for employment) explained about 23% of the variance. The younger they were the higher was the level of role stress. Also, if they were working for an economic reason (to support the family), they tended to be more stressed out. The results of this study could be utilized as baseline data for policy-making, consultation, and development of educational programs for housewives working in sales departments, an area that has hardly been explored.

The contamination of chlorinated ethenes at an industrial complex, Wonju, Korea, was examined based on sixteen rounds of groundwater quality data collected from 2009 to 2013. Remediation technologies such as soil vapor extraction, soil flushing, biostimulation, and pumping-and-treatment have been applied to eliminate the contaminant sources of trichloroethylene (TCE) and to prevent the migration of TCE plume from remediation target zones. At each remediation target zone, temporal monitoring data before and after the application of remediation techniques showed that the aqueous concentrations of TCE plume present at and around the main source areas decreased significantly as a result of remediation technologies. However, the TCE concentration of the plumes at the downstream area remained unchanged in response to the remediation action, but it showed a great fluctuation according to seasonal recharge variation during the monitoring period. Therefore, variations in the contaminant flux across three transects were analyzed. Prior to the remediation action, the concentration and mass discharges of TCE at the transects were affected by seasonal recharge variation and residual DNAPLs sources. After the remediation, the effect of remediation took place clearly at the transects. By tracing a time-series of plume evolution, a greater variation in the TCE concentrations was detected at the plumes near the source zones compared to the relatively stable plumes in the downstream. The difference in the temporal profiles of TCE concentrations between the plumes in the source zone and those in the downstream could have resulted from remedial actions taken at the source zones. This study demonstrates that long term monitoring data are useful in assessing the effectiveness of remediation practices.

This study investigated the effects of three factors-mothers' parenting beliefs; child care-home involvement; and the home learning environment - on the school readiness of 3- to 5-year-olds. The subjects were 366 children who were enrolled in child care centers located in Seoul and the Kyoungki area, and their mothers. The Structural Equation Modeling (SEM) technique was employed to test the pathways to children's school readiness as indicated by the child's abilities in vocabulary, math and reading. The results showed that mothers' stronger beliefs in their responsibilities in their children's academic and behavioral development predicted greater involvement in child care and better quality in the home learning environment. Likewise, the quality of the learning environment predicted the extent of the child's readiness for school. No direct relation was found between child care involvement and the child's school readiness. The results imply that multiple factors - parental, child-care-related, and home environmental- explain the extent to which the child is prepared to adjust to scholastic life.

Gravity study was carried out to investigate the structure and total mass of the Bupyeong silver deposits closely related to formation of the Bupyeong caldera. Survey region covers $3.3{\times}6.6km^2$ over silver deposits and is comprised of 334 gravity measurement stations. An apparent regional gravity trend parallel to the west coast line is mainly attributed to isostasy. A least square isostasy model was used for the regional correction. A Fortan subroutine was coded to calculate 3-dimensional subsurface model. The calculated gravity values from the 3-dimensional model of the caldera with silver deposits agree with observed anomalies relatively well. Gravity anomaly due to Bupyeong silver deposits reaches to +3.5 mgal from the background value and anomaly due to the caldera reaches to -4 mgal. But the maximum negative anomaly of the caldera would be much greater at its center. The total mass of silver deposits calculated from the subsurface model is $4.19{\times}10^9$ tons. Although the economic part of silver deposits depends on the grade of orebody, we expect that there are still large amount of silver reserves in Bupyeong area.

The objectives of this study were to investigate the effect of the physical properties of wick on the water absorption of substrate. Physical properties of wick in this study were cotton composition, width and length. The water Infiltration rate through the wick was 0.24 ㎝/s at 90 -95% cotton content, which was faster than at 80-85% (0.13 cm/s) and 70-75% (0.08 cm/s). As the cotton content increased, the water absorption of substrate became greater : the amount of absorbed water was about 5-7g higher at 90-95% than at 80-85% and 70-75% at a wick width of 1 ㎝, the velocity of water absorption through the wick was fastest with 0.25 ㎝ㆍs/sup -1/. The amount of absorbed water was higher at 3 ㎝ than at 1 and 2 ㎝. However, the water absorption rate through the cross - sectional area of wick (g H₂O /㎠/hr) was higher at a wick width of 2 ㎝ than at those of 1 and 3 ㎝. The amount of absorbed water in the substrate was higher at 2 : 1 than at 1 : 1 (length in substrate : length out of substrate). Absorbed water amount was larger at 30-40% initial moisture content than any other treatment.

The purpose of this study is to examine the influence of family mealtime on the childrens' school adaptation. This study uses data from the 2012 Survey on Child Education and School Involvement of Parents by the Center for Family-School Partnership Policy Research at Seoul National University. Survey data was collected from 1500 parents with school-aged children. For the data analysis, Chi sqaure test and hierarchical linear regression analyses were conducted. The results of these analyses showed that the numbers of family meals shared averaged 4.26 times per week for breakfast and 4.33 times per week for dinner. There were significant differences in the number of family meals shared together according to school level, residence area, and parent employment status, and household income. In addition, childrens' school adaptation was significantly different depending on school level, parent gender, parent education, and parent employment status. Finally, according to the hierarchical regression analyses, the number of family meals shared significantly predicted childrens' school adaptation. The greater number of family meals shared, the stronger the childrens' school adaptation. These results indicate that family mealtime has a positive effect on childrens' school adaptation. This study suggests that family mealtime is an indicator of family strength and it needs to guarantee family shared time at least to have a dinner together. This study could provide grounds for making family policy and education policy in order to guarantee family shared time.

To investigate the possible applications of plants to remediate heavy-metal-contaminated soil, a pilot experiment was performed for four years in a reclaimed dredging area using two Alnus species, i.e., Alnus firma and Alnus hirsuta. In a comparison of phytomass of the two species at two different planting densities, the phytomass of Alnus planted at low density was twice as high as that of Alnus planted at high density after four years. The Alnus species showed active acclimation to the heavy-metal-contaminated soil in a reclaimed dredging area. A. hirsuta showed greater accumulation of phytomass than A. firma, indicating that it is the better candidate for the phytoremediation of heavy-metal-contaminated soils. In the pilot system, Alnus plants took metals up from the soil in the following order; Pb > Zn > Cu > Cr > As > Cd. Uptake rates of heavy metals per individual phytomass was higher for Alnus spp. planted at low density than those planted at high density in the pilot system. Low plant density resulted in higher heavy metal uptake per plant, but the total heavy metal concentration was not different for plants planted at low and high density, suggesting that the plant density effect might not be important with regard to total uptake by plants. The quantity of leached heavy metals below ground was far in excess of that taken up by plants, indicating that an alternative measurement is required for the removal of heavy metals that have leached into ground water and deeper soil. We conclude that Alnus species are potential candidates for phytoremediation of heavy-metal- contaminated surface soil in a reclaimed dredging area.

도시기후와 같은 소기후를 연구하기 위하여는 도시는 물론 그 주변의 농촌지역에 이르기까지 조밀한 기상관측망이 필요하다. 그러나 한국에서 뿐만 아니라 선진제국에서도 기상관측망의 밀도가 도시기후를 파악하기에 충분할 만큼 조밀하지 못한 실정에 있다. 이러한 상항하에서 도시기후에 관하여 연구하려면 기초자료부터 측정하여야하는 어려움이 있으며, 따라서 그 연구의 필요성은 절감하면서도 실제적인 연구는 극히 부진하여 그 범위도 대단히 한정되어 있다. 1960년에 TIROS 1호가 미국에서 발사된 이래 다수의 기상위성이 궤도상에서 선회하며 많은 기상정보를 지상으로 보내주고 있다. 그리하여 현장관측이 어려운 각종 기상현상에 관한 정보를 짧은 시간안에, 그리고 경우에 따라서는 적은 비용으로 입수할 수 있게 됨으로써 기상연구에 박차가 가하여지게 되었다. 특히 최근에는 컴퓨터 프로그램의 발달과 더불어 해상력이 1km인 AVHRR의 영상을 대축척으로 확대하여 사용할 수 있게 되는 한편 여러가지 오류도 수정할 수 있게 되었다. 그리고 이들 위성으로부터 관측된 열적외선 영상은 도시열섬을 나타내는데 있어서 중용한 자료로 사용할 수 있게 되었다. 본 연구에서는 원격탐사 기법에 의한 도시열섬 연구의 가능성을 타진하여 보고자 NOAA AVHRR 영상을 이용하여 남한지역의 도시열섬의 존재와 수도권지역 열섬의 강도 및 형태를 알아보고 나아가 도시열섬과 여러 도시현상간의 관계를 밝혀 보고자 한다.
