Objective: The aims of this study is to investigate the internal and external environment surrounding fathers and to promote play-participation with children and father-Infants Intimacy by identifying the influence of a father's belief concerning gender-equal parental role and the mother's roles as a gatekeeper. Methods: The participants of this study were 291 fathers who had infants ranging from 1-36 months of age and were living in Seoul and South Chungcheong Province. The data were collected through the questionnaires and analyzed using the SPSS 24.0. Results: The main results are as follows.

액화 천연 가스는 도시가스로 공급되기 위해 기화의 과정을 거치는데 이 때 약 800 kJ/kg의 냉열이 발생한다. 현재 이 에너지는 모두 바다로 버려지고 있어 에너지 재순환 관점에서 보면 아주 심각한 에너지 낭비를 초래하고 있다. 본 연구에서는 이 점에 착안하여 버려지는 액화 천연 가스의 냉열을 활용할 수 있는 해수담수공정을 제안하고 이 공정을 최적화하여 고유 전력 소비와 경제성에 대해 분석하였다. 그 결과 제안된 공정의 에너지 소모량은 -5.2 kWh/m³, 담수생산 단가는 0.148 USD/m³으로 계산되어 현재까지 개발된 어떤 공정보다도 우수함을 확인하였다.

Japan's modern fashion, which already became distinguished in the world fashion market, creates originality by identifying its own color as well as shape and details from its tradition. The purpose of this study was to draw the results of examining the perceived meanings of color revealed in the culture, arts and clothing color of Heian period in Japan and searching them in contemporary Japanese fashion. The scope of study was the perceived meaning of color in Heian period and Japanese contemporary fashion. In the methodologies, the literature and the empirical study focused on Heian's culture, including art history, ethnology, and the history of clothing and the contemporary fashion collection. Japan's original middle colors and intermediate colors began to be created in Heian period. The color aesthetic characteristics of Heian period appeared the beauty of compound color, layered color, overlapped color in Japanese contemporary fashion.

This study classifies short front long back skirts from the Joseon Dynasty by style type, identifies their formative characteristics based on their external morphological properties and internal composition, and examines their correlation with Korean thought. A literature review and empirical research were conducted for this study. The style of short front long back skirts is classified as inverted "b"-shaped, lower lip, wavy, trapezoid with a raised center hem, or half-circle. As such, this skirt possesses the formative properties of imbalance, variability of shape, intentional three-dimensionality, and confluence. In other words, with an imbalance resulting from the difference in length between the front and back, these skirts are characterized by variability in shape created by intentional three-dimensionality expressed as intentional three-dimensional beauty, the confluence of planes and dimensions, as well as of materials and colors. These properties are correlated with Korean ways of viewing the world. This study contributes to the development of Korean designs.

Objective: This study aims to provide empirical data on epidemic management measures and childcare teacher education in centers. It examines the relationship between infectious disease knowledge, health control knowledge, and self-efficacy in relation to the practice of preventive behaviors among infant and toddler teachers during the COVID-19 pandemic. Methods: The study involved 300 teachers from Seoul and Gyeonggi Province. Data were collected through questionnaires and analyzed using SPSS 23.0. Results: The study found that there is a positive relationship between childcare teachers' knowledge of infectious diseases and their engagement in preventive behavior. Additionally, internal control among the health care factors of childcare teachers also showed a positive relationship. Furthermore, the study revealed that the self-efficacy of childcare teachers is positively associated with their practice of preventive behavior. Overall, infectious disease knowledge, internal control measures, and self-efficacy were all found to have positive relationships with preventive behavior. Conclusion/Implications: This study proposes a new direction for future teacher education by highlighting the effectiveness of psychological factors, specifically health control materials and self-efficacy, in addition to focusing on improving infectious disease knowledge.

To produce buckwheat sprouts, buckwheats were germinated at $23{\pm}2^{\circ}C$ up to 8 days in total darkness. In proximate analysis, moisture content increased from 13.87% of buckwheat groats to 93.75% of buckwheat sprouts on the 8th day of germination. On dry weight basis, lipid and ash contents increased like as protein content increased from 13.45% to 21.82% while carbohydrate content decreased due to enzyme hydrolysis. Amino acids were rich in glutamic acid, aspartic acids, and lysine, and also the ratio of the essential amino acids to total amino acids increased from 26.84% to 36.84%. Vitamin C did not exist in buckwheat groats but its content has continued to increase as far as 99.56 mg/100 g buckwheat sprouts. Rutin continued to increase by HPLC analysis from 4.71 mg/100 g buckwheat groats to 1,524 mg/100 g buckwheat sprouts. In analysis of organic acids, oxalic, maleic, and citric acids were commonly found in buckwheat sprouts. Fagopyrin was found almost none in buckwheat sprouts. In conclusion, the conversion of buckwheat seeds into sprouts through germination in darkness results in physically different final product with nutritional changes such as higher content of rutin, generation of vitamin C, abundance of the essential amino acids, and the existence of fagopyrin on very little.

This study was conducted to evaluate the influence of Lactobacillus bulgaricus and/or Sterptococcus thermophilus on the fermentation of yoghurt containing 5% (w/v) buckwheat sprouts. The results revealed that after 12 hours of fermentation the appropriate pH, titratable acidity and number of viable cells were attained. At that time, the rutin content of the buckwheat sprout-added yoghurt prepared by the mixed culture method was not changed, but the quercetin content increased greatly. Conversely, the rutin content of yoghurt that only contained Streptococcus thermophilus was decreased while the quercetin content was increased. The total phenol contents as well as the DPPH radical scavenging activities of both the mixed culture and Streptococcus thermophilus yoghurt did not differ significantly. Taken together, the results revealed that the use of a mixed culture of Lactobacillus bulgaricus and Streptococcus thermophilus during the preparation of buchwheat sprout-added yoghurt was desirable due to the decrease in pH and increase in titratable acidity and viable cells that occurred after 12 hr of fermentation. Moreover, phytochemicals in buckwheat sprouts such as rutin, quercetin and phenol compounds were comparatively increased during fermentation and influenced the antioxidant activity in buckwheat sprout-added yoghurt.
