This study investigates whether women's wear brands' sizing systems reflect the body size and shape of their target age customers. This study classified 17 women's wear brands into three target age groups (20-30s, 30-40s, and 40-50s) and surveyed their body sizing systems for jacket items. The distribution of bust circumference and hip circumference of brands' sizing systems were compared with the size distribution of women in the 7th SizeKorea data. The brands targeting 20-30s fully produced five sizes which are the highest coverage rate, but the brands targeting 30-40s produced three sizes, and the brands targeting 40-50s produced one size. Regarding the body types, 60.0% of 20-30s target brands and 42.9% of 30-40s target brands reflected N type which is the average body type of each age group. However, the rest of the brands, including all 40-50s target brands, reflected A type which covered small portions of women. For each age group, 6 sizes with 24.0-29.0% coverage rates were proposed. With regard to the 88-94 size, three age groups overlapped: the 82-91 size was overlapped between the 20-30s and the 30-40s groups along with the 85-91 and 88-91 sizes that overlapped between the 30-40s and 40-50s groups.

This study examined the fashion culture of 20-30s working women through clothing norm relationships in the workplace. A literature research was conducted along with qualitative research, in-depth interviews in order to understand the domestic working environment and fashion culture such as lifestyle and consumer culture characteristics of 20-30s working women. The results were: First, it showed that the increased number of members having various inclinations caused subcultures through an increase of women's economic activities and transition to a knowledge-information society in domestic work places that changed into a business casual that recognized employees' autonomy and diversity. Second, in the working place, clothing norms coexist as stipulated by statutes, company rules, and official documents as well as others implied by experiences of sanction against members. Workplace closing norms are classified into norms of exposure that draw attention to clothes and casual clothes. Third, it showed that factors pressuring clothing norms are classified as external pressures and by spontaneous self-censorship that cause conflict and confusion with working women's fashion according to the degree of pressure. Two kinds of pressure by others (or types of departments and members) were observed.

The aim of this study is to investigate the effect of five different combinations including: sand 70%, bentonite 30% (S₇₀B₃₀)- sand 80%, bentonite 20% (S₈₀B₂₀)- sand 80%, organophilic 20% (S₈₀M₂₀)- sand 60%, bentonite 20%, organophilic 20% (S₆₀B₃₀M₂₀) and sand 75% - bentonite 15% - organophilic 10% (S₇₅B₁₅M₁₀) on landfill linear structure in order to decrease phenol leaching. Hydraulic conductivity and adsorption behavior of the samples were investigated. The results demonstrated that the lowest hydraulic conductivity coefficient ($1.16{\times}10^{-11}{\frac{m}{s}}$) was obtained for S₇₀B₃₀. Furthermore, adding more than 20% of bentonite had no significant effect on reducing permeability. Moreover, Freundlich isotherm was introduced as the best model explaining adsorption behaviour due to its highest determination coefficient (0.945). The best samples for adsorption capacity of phenol and for both permeability and adsorption are S₈₀M₂₀ and S₆₀B₃₀M₂₀, respectively. Although the presence of bentonite was effective in reducing hydraulic conductivity, organic clay had no considerable impact on reducing permeability. Though, it's an exceptional role in adsorbing organic contaminants including phenol cannot be ignored. To meet all regulatory constraints, the optimal compound is made up of 10.2% of bentonite and 2.8% of organophilic clays with a minimized cost of 13.64 ($/ton).

This study has examined the 20's and the 30's Korean who have a desire, 'to be getting younger' and how to relate what appearance management-behavior they follow. The methodology of this study used both theoretical and quantitative research for an empirical study. First, a theoretical study researched a big stream of the 20's and the 30's Koreans' to be getting younger' on articles based on the social and cultural background of the past 30 years that defined various concepts of age through previous research. Data was also collected via SMS for five months (August to December 2014) and 96 Korean participants in their 20's and the 30's who have lived in and around Seoul. The results of the survey analysis showed that the desire of 'to be getting younger' irrelevant to the age among Korean young people. In addition, this tendency to be the ideal age as being younger is realized by appearance management sort of skin care or clothing styling among 20's and the 30's Korean. This study suggested a phenomenon, 'to be getting younger' in Korean society would lead to an alternative sort of age that targets individual taste rather than the chronological age in the apparel market.

과채류는 육묘의 중요성이 큰 것으로 알려져 있는데, 딸기는 육묘가 80%라고 할 정도로 육묘의 비중이 큰 것으로 인식하고 있다. 그러나 아직 딸기의 수경재배 육묘에 대한 연구는 국내외 모두 많지 않다. 딸기는 품종에 따라 생육 특성의 차이가 확연하게 다르므로 품종마다 적합한 비료 조성, 비료 농도와 pH 관리, 고형배지 종류별 적절한 급액량 구명 등이 필요한데, 딸기 수경재배 육묘에서 우선적으로 구명할 사항은 배양액의 농도관리 기술이라고 할 수 있다. '대왕(大王)' 딸기 모주를 2012년 3월 28일에 코코피트를 충진한 수경재배 육묘 벤치에 정식하였다. 육묘기간 동안의 배양액 처리구는 각각 EC $0.6dS{\cdot}m^{-1}$의 배양액을 30일간 공급한 후 20일간 물만 공급한 구[0.6(30) + 20], EC $1.2dS{\cdot}m^{-1}$의 배양액을 30일간 공급한 후 20일간 물만 공급한 구[1.2(30) + 20], 그리고 EC $1.2dS{\cdot}m^{-1}$의 배양액을 50일간 공급한[1.2(50)] 3가지 처리구로 하였다. 9월 20일에 코코피트를 충진한 수경재배 벤치에 정식하고, 야마자키 조성 딸기배양액을 이용 하여 EC $0.6-0.8dS{\cdot}m^{-1}$로 관리하였다. 정식 후 지상부 생육, 개화율 그리고 정화방의 과실 품질을 조사하였다. 엽병장, 엽장, 엽폭 그리고 크라운 직경 모두 [1.2(50)], [1.2(30) + 20], [0.6(30) + 20] 처리구 순으로 육묘기의 배양액 농도가 높을수록 생육이 양호하였다. 그러나 생육이 진전됨에 따라 처리구 간의 생육차이는 점차 사라졌고 특히, 크라운의 직경은 처리구 간에 거의 차이가 없을 정도가 되었다. 개화는 [0.6(30) + 20], [1.2(30) + 20], [1.2(50)] 처리구 순으로 빨랐는데, 특히 [0.6(30) + 20] 처리구는 다른 처리구보다 월등하게 빠른 개화율을 나타내어 육묘기의 저농도의 배양액 관리가 '대왕' 딸기의 개화에는 유리한 것으로 생각되었다. 과장, 과경 및 과실의 경도는 처리구간에 통계적으로 유의한 차이를 나타내지 않았다. 과중은 [1.2(50)] 처리구가 다른 처리구보다 유의하게 높았다. 그러나 과실의 고형물 함량은 [1.2(50)] 처리구에서 가장 낮았고 다른 두 처리구에서 높은 수치를 나타내었다. 본 실험의 결과에서, 딸기의 수경재배 육묘기 동안 적정한 배양액의 농도 관리는 EC $0.6dS{\cdot}m^{-1}$로 30일간 공급한 후에 20일간 수분만 공급하는 것이 좋을 것으로 생각되었다.

Objectives: This study was intended to investigate adults' health behaviors and eating habits according to their levels of social media use. Methods: From May 27 to July 11, 2022, an online survey was conducted of 452 male and female social media users in their 20s and 30s, and their eating habits and health behaviors were compared and analyzed according to their degree of social media use. For each of the three levels of food content use, the frequency of social media content use, and the total score range of average social media viewing time per day were divided into three parts, and a group with a score of less than 2 points was classified as low-use; a group with a score of 2 or more and less than 3 points was classified as middle-use; and a group with a score of 3 points or more was classified as high-use. Results: The use of food content was higher in women than in men (P < 0.001), and higher in those in their 20s than in those in their 30s (P < 0.001). The group with a high level of food content use showed a higher rate of post-use hunger than the group with a low level (P < 0.01). The experience of eating after using food content was also higher in the group with a high level of use than in the group with a low level of use (P < 0.001). The group with a normal or high level of food content use had more negative eating habits than the group with a low level. Conclusions: The study highlighted the need to provide desirable food content to people in their 20s and 30s with negative eating habits and to promote them so that they can use the right healthy nutrition-related content.
