가족의 돌봄 부담을 줄이기 위해 공적돌봄제도가 도입되었지만, 공적돌봄의 확대가 가족돌봄의 감소로 이어지는지에 대해서는 단언하기가 쉽지 않다. 이론적으로 공적돌봄의 역할과 기능에 따라 가족돌봄을 대체 혹은 보완하는지에 대해 다양한 관계가 예측되고 있고(대체모형, 위계적 보상모형, 과업특정모형, 보충모형, 보완모형), 선행연구에서도 국가와 시기, 연구방법에 따라 일관되지 않은 결과들이 보고되고 있다. 이에 본 연구에서는 재가서비스를 이용하는 노인을 중심으로, 한국 사회에서 공적돌봄과 가족돌봄이 어떠한 관계를 보이는지 분석하였다. 분석자료는 고령화연구패널조사의 2-6차 자료를 이용하였고, 분석대상은 공적돌봄을 한번 이상 이용한 경험이 있는 55세 이상의 노인 262명이다. 분석방법은 돌봄이행을 기준으로 구분한 하위집단별로 돌봄내용의 종단적인 변화 정도를 비교하는 방법과, 패널자료의 특성을 이용하여 가족돌봄에 영향을 미치는 미관측 이질성의 영향을 통제하는 고정효과 회귀분석을 적용하였다. 분석결과, 공적돌봄에 의지하는 노인은 이전에 비해 가족돌봄에 덜 의지하는 것으로 나타나, 두 가지 돌봄 사이의 부적인 관계가 확인되었다. 나아가서 이 연구는 공적돌봄에 진입한 사례와 공적돌봄을 유지 또는 이탈한 사례들을 구분하여, 돌봄유형 간 관계가 어떠한 차이를 보이는지 확인하였다. 두 이행과정 모두에서 부적인 관계가 유지되었지만, 공적돌봄에 진입하는 단계에서는 부적인 관계의 정도가 비교적 미미한 수준이었던 반면, 공적돌봄을 유지하거나 이탈하는 단계에서는 상대적으로 강한 부적 관계가 나타났다. 즉, 공적돌봄을 신청하여 수급하는 시점에서는 공적돌봄이 증가하더라도 가족돌봄이 크게 감소하지 않으나, 공적돌봄을 종료하고 가족돌봄에 의지하는 시점에서는 가족돌봄이 크게 증가하였다. 결과적으로, 이는 공적돌봄에 비해 가족돌봄을 선호하는 경향이 반영된 결과로 보이며, 한국 사회에서 공적돌봄과 가족돌봄의 관계는 위계적 보상모형에 가깝다고 할 수 있겠다. 본 연구의 이러한 결과는 공적돌봄과 가족돌봄의 관계가 돌봄이행 단계에 따라 차이를 보인다는 것을 보여준다. 또한, 여러 하위집단 중에서 공적돌봄에서 가족돌봄으로 이행한 사례의 가족 구성원이 다른 집단에 비해 가장 큰 돌봄 부담을 지니고 있음을 확인하였다.

The deciduous shrubs, Lindera sericea belonging to family Lauracea are distributed in Mt. Chogye and Mudeung locally. To estimate the community structure of this shrub, the relationship between the floristic composition and environmental factors of 20 sites in Mt. Chogye were investigated. L. sericea community distributed at the hum양 zone of altitude 305-480 m in ES and NE slope of $15~30^{\circ}$. The floristic composition of this communities consisted of 17-32 species varied with sites. Sasa borealis, Sapium japonicum, and Quercus serrata were the constant species over 90%. The forest vegetation was classified as Sasa borealis-Lindera sericea community, and the Sasa borealis-Meliosma oldhamii, and Sasa borealis-Callicarpa japonica were as subunit community. Acidity, organic matter content, inorganic phophate, potassium, calcium, magnesium, cation exchange capacity and conductivity were determined as environmental factors. Diameter of stem at ground surface and stem, distribution area and growth property of this plant were investigated, and this plant was presumed to be a relic endemic species.

The demand for complementary and alternative medicine (CAM) is increasing worldwide. High-technology medicine is not always effective and is often accompanied by neglected self-care and high cost. Also, conventional medicine has become dependent on expensive technological solutions to health problems. Integrated medicine is not simply a synonym for complementary medicine. It involves the understanding of the interaction of the mind, body, and spirit and how to interpret this relationship in the dynamics of health and disease. Integrative medicine shifts the orientation of the medical practice from a disease-based approach to a healing-based approach. In South Korea, CAM education was first provided 20 years ago, and integrative medicine is becoming part of the current mainstream medicine. Increasing numbers of fellowships in integrative medicine are being offered in many academic health centers in the U.S. Also, it has emerged as a potential solution to the American healthcare crisis and chronic diseases, which are bankrupting the economy. It provides care that is patient-centered, healing-oriented, emphasizes the therapeutic relationship, and uses therapeutic approaches originating from conventional and alternative medicine.

Beginning from the recognition of FtsZ as a bacterial tubulin homolog in the early 1990s, many bacterial cytoskeletal elements have been identified, including homologs to the major eukaryotic cytoskeletal elements (tubulin, actin, and intermediate filament) and the elements unique in prokaryotes (ParA/MinD family and bactofilins). The discovery and functional characterization of the bacterial cytoskeleton have revolutionized our understanding of bacterial cells, revealing their elaborate and dynamic subcellular organization. As in eukaryotic systems, the bacterial cytoskeleton participates in cell division, cell morphogenesis, DNA segregation, and other important cellular processes. However, in accordance with the vast difference between bacterial and eukaryotic cells, many bacterial cytoskeletal proteins play distinct roles from their eukaryotic counterparts; for example, control of cell wall synthesis for cell division and morphogenesis. This review is aimed at providing an overview of the bacterial cytoskeleton, and discussing the roles and assembly dynamics of bacterial cytoskeletal proteins in more detail in relation to their most widely conserved functions, DNA segregation and coordination of cell wall synthesis.

The latest measure of the relative evolutionary age of protein structure families was applied (based on taxonomic diversity) using the protein structural interactome map (PSIMAP). It confirms that, in general, protein domains, which are hubs in this interaction network, are older than protein domains with fewer interaction partners. We apply a hypothesis of 'biological network evolution' to explain the positive correlation between interaction and age. It agrees to the previous suggestions that proteins have acquired an increasing number of interaction partners over time via the stepwise addition of new interactions. This hypothesis is shown to be consistent with the scale-free interaction network topologies proposed by other groups. Closely co-evolved structural interaction and the dynamics of network evolution are used to explain the highly conserved core of protein interaction pathways, which exist across all divisions of life.

Phospholipase D (PLD), a superfamily of signaling enzymes that most commonly generate the lipid second messenger Phosphatidic Acid (PA), is found in diverse organisms from bacteria to man and functions in multiple cellular pathways. A fascinating member of the family, MitoPLD, is anchored to the mitochondrial surface and has two reported roles. In the first role, MitoPLD-generated PA regulates mitochondrial shape through facilitating mitochondrial fusion. In the second role, MitoPLD performs a critical function in a pathway that creates a specialized form of RNAi required by developing spermatocytes to suppress transposon mobilization during meiosis. This spermatocyte-specific RNAi, known as piRNA, is generated in the nuage, an electron-dense accumulation of RNA templates and processing proteins that localize adjacent to mitochondria in a structure also called intermitochondrial cement. In this review, we summarize recent findings on these roles for MitoPLD functions, highlighting directions that need to be pursued to define the underlying mechanisms.

Structure-dependent integration methods seem promising for structural dynamics applications since they can integrate unconditional stability and explicit formulation together, which can enable the integration methods to save many computational efforts when compared to an implicit method. A newly developed structure-dependent integration method can inherit such numerical properties. However, an unusual overshooting behavior might be experienced as it is used to compute a forced vibration response. The root cause of this inaccuracy is thoroughly explored herein. In addition, a scheme is proposed to modify this family method to overcome this unusual overshooting behavior. In fact, two improved formulations are proposed by adjusting the difference equations. As a result, it is verified that the two improved formulations of the integration methods can effectively overcome the difficulty arising from the inaccurate integration of the steady-state response of a high frequency mode.

This study examines the effects of time spent with parents and peers on generational differences in children's externalizing behavior problems in immigrant families. Using the Child Development Supplement and Time Diaries from the Panel Study of Income Dynamics, we found that first and second generation children exhibited fewer externalizing behavior problems than did third generation children, despite their lower socioeconomic status. First and second generation children spent more time with either one or both parents, and less time with peers, on the weekend day than did third generation children. We found a marginal but beneficial effect of time spent with fathers on the weekday, but not on the weekend day. The implications are that time spent with fathers on weekdays differs from time spent with fathers on the weekend, and that promoting immigrant father involvement on the weekday through school or community programs could benefit immigrant children.

The characteristics of poverty can be comprehensively revealed from the two angles of income and multidimensional. This paper compares China's rural income poverty measure with multidimensional poverty index using data from China Family Panel Studies (CFPS) by focusing on the static and dynamic disparities, and analyzes the factors influencing poverty through the Logit model. The results show that there exists a substantial mismatch in who is deemed poor, 60 percent of multidimensional poverty households are not considered poor in terms of income poverty, and 70 percent of income poverty households are not considered poor in terms of multidimensional poverty; There is a high level of disparity between the dynamics of the two measures of poverty. Among those who rose in the income dimension, only about 7 percent also rose in the multidimensional measure from 2016 to 2018.
