본 연구의 목적은 어머니의 수면의 질이 자녀의 문제행동에 미치는 영향에서 자녀의 수면 문제와 어머니의 양육스트레스가 순차적으로 매개하는지 검증하는 것이다. 이를 위해 1.5세에서 5세 영유아 어머니를 대상으로 자기 보고식 설문을 실시하였다. 순차적 매개 효과의 유의성 검증을 위해 Preacher와 Hayes(2008)이 개발한 Process Macro를 사용하여 회귀분석과 부트스트래핑을 실시하였다. 그 결과, 어머니의 수면의 질은 유아의 수면 문제와 어머니의 양육 스트레스를 순차적으로 경유하여 유아의 문제행동에 유의한 영향을 미치는 것으로 나타났다. 본 연구는 자녀의 문제행동에 영향을 미치는 부모 변인 가운데 하나인 모의 수면의 질이 어떤 매커니즘을 통해 자녀의 문제행동에 영향을 미치는지를 규명하였으며 이 결과를 바탕으로 부모교육 현장에서 중요한 교육 자료를 제시하였다. The purpose of this study is to understand mediating effect of children’s sleep problem and parenting stress in the effects of children’s problem behavior on the mother’s sleep quality. For this, the self-report scale of mother’s sleep quality, children’s problem behavior, children’s sleep problem, and parenting stress was conducted targeting 239 children. In the result of bootstrapping using the Process Macro to verify the significance of mediating effects, mother’s sleep quality had direct effects on the children’s problem behavior. Specifically that mother’s sleep quality increases children’s sleep problems, and increased children’s sleep problems increase parenting stress increases, providing a negative parenting environment for children, thereby increasing their problem behavior. This study provided data to understand the mother’s sleep quality, one of the parent variables affecting children’s problem behavior, and provided parenting information to parents by examining the relationship between mother’s sleep quality and children’s sleep. In the counseling scene, empirical implications for counseling intervention were presented to the counselor.

Impact of abnormal climate events on the production of Italian ryegrass as a season in Korea

( Moonju Kim ),( Kyungil Sung ) 한국축산학회(구 한국동물자원과학회) 2021 한국축산학회지 Vol.63 No.1

This study aimed to assess the impact of abnormal climate events on the production of Italian ryegrass (IRG), such as autumn low-temperature, severe winter cold and spring droughts in the central inland, southern inland and southern coastal regions. Seasonal climatic variables, including temperature, precipitation, wind speed, relative humidity, and sunshine duration, were used to set the abnormal climate events using principal component analysis, and the abnormal climate events were distinguished from normal using Euclidean-distance cluster analysis. Furthermore, to estimate the impact caused by abnormal climate events, the dry matter yield (DMY) of IRG between abnormal and normal climate events was compared using a t-test with 5% significance level. As a result, the impact to the DMY of IRG by abnormal climate events in the central inland of Korea was significantly large in order of severe winter cold, spring drought, and autumn low-temperature. In the southern inland regions, severe winter cold was also the most serious abnormal event. These results indicate that the severe cold is critical to IRG in inland regions. Meanwhile, in the southern coastal regions, where severe cold weather is rare, the spring drought was the most serious abnormal climate event. In particular, since 2005, the frequency of spring droughts has tended to increase. In consideration of the trend and frequency of spring drought events, it is likely that drought becomes a NEW NORMAL during spring in Korea. This study was carried out to assess the impact of seasonal abnormal climate events on the DMY of IRG, and it can be helpful to make a guideline for its vulnerability.

Assessment of causality between climate variables and production for whole crop maize using structural equation modeling

( Moonju Kim ),( Kyungil Sung ) 한국축산학회(구 한국동물자원과학회) 2021 한국축산학회지 Vol.63 No.2

This study aimed to assess the causality of different climate variables on the production of whole crop maize (Zea mays L.; WCM) in the central inland region of the Korea. Furthermore, the effect of these climate variables was also determined by looking at direct and indirect pathways during the stages before and after silking. The WCM metadata (n = 640) were collected from the Rural Development Administration’s reports of new variety adaptability from 1985-2011 (27 years). The climate data was collected based on year and location from the Korean Meteorology Administration’s weather information system. Causality, in this study, was defined by various cause-and-effect relationships between climatic factors, such as temperature, rainfall amount, sunshine duration, wind speed and relative humidity in the seeding to silking stage and the silking to harvesting stage. All climate variables except wind speed were different before and after the silking stage, which indicates the silking occurred during the period when the Korean season changed from spring to summer. Therefore, the structure of causality was constructed by taking account of the climate variables that were divided by the silking stage. In particular, the indirect effect of rainfall through the appropriate temperature range was different before and after the silking stage. The damage caused by heat-humidity was having effect before the silking stage while the damage caused by night-heat was not affecting WCM production. There was a large variation in soil surface temperature and rainfall before and after the silking stage. Over 350 mm of rainfall affected dry matter yield (DMY) when soil surface temperatures were less than 22℃ before the silking stage. Over 900 mm of rainfall also affected DMY when soil surface temperatures were over 27℃ after the silking stage. For the longitudinal effects of soil surface temperature and rainfall amount, less than 22℃ soil surface temperature and over 300 mm of rainfall before the silking stage affected yield through over 26℃ soil surface temperature and less than 900 mm rainfall after the silking stage, respectively.

Establishment of Immortalized Primary Human Foreskin Keratinocytes and Their Application to Toxicity Assessment and Three Dimensional Skin Culture Construction

( Moonju Choi ),( Minkyung Park ),( Suhyon Lee ),( Jeong Woo Lee ),( Min Chul Cho ),( Minsoo Noh ),( Choongho Lee ) 한국응용약물학회 2017 Biomolecules & Therapeutics(구 응용약물학회지) Vol.25 No.3

In spite of frequent usage of primary human foreskin keratinocytes (HFKs) in the study of skin biology, senescence-induced blockage of in vitro proliferation has been a big hurdle for their effective utilization. In order to overcome this passage limitation, we first isolated ten HFK lines from circumcision patients and successfully immortalized four of them via a retroviral transduction of high-risk human papillomavirus (HPV) E6 and E7 oncogenes. We confirmed expression of a keratinocyte marker protein, keratin 14 and two viral oncoproteins in these immortalized HFKs. We also observed their robust responsiveness to various exogenous stimuli, which was evidenced by increased mRNA expression of epithelial differentiation markers and pro-inflammatory genes in response to three reactive chemicals. In addition, their applicability to cytotoxicity assessment turned out to be comparable to that of HaCaT cells. Finally, we confirmed their differentiation capacity by construction of well-stratified three dimensional skin cultures. These newly established immortalized HFKs will be valuable tools not only for generation of in vitro skin disease models but also for prediction of potential toxicities of various cosmetic chemicals.

Review : Immortalization of Primary Keratinocytes and Its Application to Skin Research

( Moonju Choi ),( Choongho Lee ) 한국응용약물학회 2015 Biomolecules & Therapeutics(구 응용약물학회지) Vol.23 No.5

As a major component of the epidermal tissue, a primary keratinocyte has served as an essential tool not only for the study of pathogenesis of skin-related diseases but also for the assessment of potential toxicities of various chemicals used in cosmetics. However, its short lifespan in ex vivo setting has been a great hurdle for many practical applications. Therefore, a number of immortalization attempts have been made with success to overcome this limitation. In order to understand the immortalization process of a primary keratinocyte, several key biological phenomena governing its lifespan will be reviewed first. Then, various immortalization methods for the establishment of stable keratinocyte cell lines will be explained. Finally, its application to a threedimensional skin culture system will be described.

Causality between climatic and soil factors on Italian ryegrass yield in paddy field via climate and soil big data

( Moonju Kim ),( Jing-lun Peng ),( Kyungil Sung ) 한국축산학회 2019 한국축산학회지 Vol.61 No.6

This study aimed to identify the causality between climatic and soil variables affecting the yield of Italian ryegrass (Lolium multiflorum Lam., IRG) in the paddy field by constructing the pathways via structure equation model. The IRG data (n = 133) was collected from the National Agricultural Cooperative Federation (1992-2013). The climatic variables were accumulated temperature, growing days and precipitation amount from the weather information system of Korea Meteorological Administration, and soil variables were effective soil depth, slope, gravel content and drainage class as soil physical properties from the soil information system of Rural Development Administration. In general, IRG cultivation by the rice-rotation system in paddy field is important and unique in East Asia because it contributes to the increase of income by cultivating IRG during agricultural off-season. As a result, the seasonal effects of accumulated temperature and growing days of autumn and next spring were evident, furthermore, autumnal temperature and spring precipitation indirectly influenced yield through spring temperature. The effect of autumnal temperature, spring temperature, spring precipitation and soil physics factors were 0.62, 0.36, 0.23, and 0.16 in order (p < 0.05). Even though the relationship between soil physical and precipitation was not significant, it does not mean there was no association. Because the soil physical variables were categorical, their effects were weakly reflected even with scale adjustment by jitter transformation. We expected that this study could contribute to increasing IRG yield by presenting the causality of climatic and soil factors and could be extended to various factors.
