Background: In this study, we evaluated the anti-cancer activity and potential molecular mechanism of 70% ethanol extracts of the root of Aralia cordata var. continentalis (Kitagawa) Y. C. Chu (RAc-E70) against human colorectal cancer cells. Methods and Results: RAc-E70 suppressed the proliferation of the human colorectal cancer cell lines, HCT116 and SW480. Although RAc-E70 reduction cyclin D1 expression at the protein and mRNA levels, RAc-E70-induced reduction in cyclin D1 protein level occurred more dramatically than that of cyclin D1 mRNA. The RAc-E70-induced downregulation of cyclin D1 expression was attenuated in the presence of MG132. Additionally, RAc-E70 reduced HA-cyclin D1 levels in HCT116 cells transfected with HA-tagged wild type-cyclin D1 expression vector. RAc-E70-mediated cyclin D1 degradation was blocked in the presence of LiCl, a $GSK3{\beta}$ inhibitorbut, but not PD98059, an ERK1/2 inhibitor and SB203580, a p38 inhibitor. Furthermore, RAc-E70 phosphorylated cyclin D1 at threonine-286 (T286), and LiCl-induced $GSK3{\beta}$ inhibition reduced the RAc-E70-mediated phosphorylation of cyclin D1 at T286. Conclusions: Our results suggested that RAc-E70 may downregulate cyclin D1 expression as a potential anti-cancer target through $GSK3{\beta}$-dependent cyclin D1 degradation. Based on these findings, RAc-E70 maybe a potential candidate for the development of chemopreventive or therapeutic agents for human colorectal cancer.

Objectives: Heart failure is a chronic disease with increasing prevalence rates despite advancements in medical technology. Korean medicine utilizes herbal prescriptions to treat heart failure, but little is known about the specific herbal medicines comprising the network of herbal prescriptions for heart failure. This study proposes a novel methodology that can efficiently develop prescriptions and facilitate experimental research on heart failure by utilizing existing databases. Methods: Herbal medicine prescriptions for heart failure were identified through a PubMed search and compiled into a Google Sheet database. NetMiner 4 was used for network analysis, and the individual networks were classified according to the herbal medicine classification system to identify trends. K-HERB NETWORK was utilized to derive related prescriptions. Results: Network analysis of heart failure prescriptions and herbal medicines using NetMiner 4 produced 16 individual networks. Uhwangcheongsim-won (牛黃淸心元), Gamiondam-tang (加味溫膽湯), Bangpungtongseong-san (防風通聖散), and Bunsimgi-eum (分心氣飮) were identified as prescriptions with high similarity in the entire network. A total of 16 individual networks utilized K-HERB NETWORK to present prescriptions that were most similar to existing prescriptions. The results provide 1) an indication of existing prescriptions with potential for use to treat heart failure and 2) a basis for developing new prescriptions for heart failure treatment. Conclusion: The proposed methodology presents an efficient approach to developing new heart failure prescriptions and facilitating experimental research. This study highlights the potential of network pharmacology methodology and its possible applications in other diseases. Further studies on network pharmacology methodology are recommended.

Objectives: The objective of this study is to examine the association between the children's psychopathology and age, intellectual quotient, and parental psychopathology in children with post-traumatic stress disorder (PTSD). Methods: The emotional and behavioral problems of 35 children with PTSD (23 boys, 12 girls, mean age, $10.26{\pm}2.47$ years) were investigated by retrospective chart review. Their parents' anxiety and depression symptoms were also investigated. We examined the correlations between children's psychopathology and their parents' anxiety and depression symptoms, as well as their age and IQ. Results: There were positive correlations between maternal trait anxiety and depression, and children's emotional problems. State and trait anxiety of children with PTSD were positively correlated with age, and attention-deficit hyperactivity disorder symptoms were negatively correlated with age. Conclusion: Our results suggest that psychiatric manifestation of children who experienced trauma could differ according to the development stage, and the treatment of children with PTSD should involve parental education about the effect of maternal emotional states on children.

Numerical analysis was conducted to characterize particle deposition onto a heated horizontal semiconductor wafer in vacuum environment. In order to calculate the properties of gas surrounding the wafer, the gas was assumed to obey the ideal gas law. Particle transport mechanisms considered in the present study were convection, Brownian diffusion, gravitational settling and thermophoresis. Averaged particle deposition velocities on the upper surface of the wafer were calculated with respect to particle size, based on the numerical results from the particle concentration equation in the Eulerian frame of reference. The deposition velocities were obtained for system pressures of 1000 Pa~1 atm, wafer heating of 0~5 K and particle sizes of $2{\sim}10^4nm$. The present numerical results showed good agreement with the available experimental ones.

In this study, the effect of pre-curing process on the enhancement of mechanical properties of IGCC-slag-based-geopolymer was studied. Pre-curing is a process in which the green geopolymer is left at room temperature for a certain period of time prior to the high-temperature curing, and it is known as increasing the strength of a specimen. Therefore, in this experiment, the compressive strength of the geopolymers was measured according to various pre-curing conditions, and microstructure and crystal phase changes were observed by SEM and XRD, respectively. The W/S ratio was determined to be 0.26, which can offer the maximum geopolymer strength with easy molding ability, and the concentration of the alkali solution was 15 M. Pre-curing was performed at room temperature for 0 to 27 days. Compressive strength of the geopolymer made with pre-curing process increased by 36~87 % compared with the specimens made with no pre-curing process. Those improved compressive strength for the pre-cured geopolymer was confirmed owing to promotion effect of pre-curing process on generation of C-S-H gel and zeolite phases, which were analyzed using by XRD and SEM measurement. 본 연구에서는 IGCC(Integrated Gasification Combined Cycle; 석탄 가스화 복합 발전)에서 배출된 용융 슬래그(이하 용융 슬래그)를 이용한 지오폴리머의 제조 시 pre-curing 공정이 지오폴리머의 물성에 미치는 영향에 대해 연구하였다. Pre-curing이란 고온양생으로 지오폴리머를 제조하기 전에, 성형체를 상온에서 일정 시간 방치하는 공정으로서, 시편의 강도를 높이는 효과가 있다고 알려져 있다. 따라서 본 실험에서는 pre-curing 조건에 따른 지오폴리머의 압축강도 특성을 측정하였으며, SEM과 XRD로 미세구조 및 결정상 변화를 관찰하였다. W/S 비율(water/solid ratio)은 사전 실험을 통해, 성형이 가능하면서 최대 지오폴리머 강도를 확보할 수 있는 0.26으로 결정하였으며, 자극제인 알칼리 용액의 농도는 15 M로 고정하였다. 상온에서 pre-curing을 0~27일 범위 내에서 실시한 결과, pre-curing 공정을 적용한 지오폴리머의 경우, 그렇지 않은 시편에 비해 압축강도가 36~87 % 증가하는 것을 확인하였다. Pre-curing 시킨 시편에서 XRD 측정 결과, C-S-H 겔(calcium silicate hydroxide gel) 상 발현이 촉진되었고 SEM을 이용한 미세구조 관찰 결과, 부정형의 zeolite 상이 더 많이 성장된 것이 관찰되었으며 이러한 상들의 생성이 강도 증진에 영향을 미친 것으로 분석되었다.

본 연구에서는, IGCC(Integrated Gasification Combined Cycle: 석탄가스화 복합발전)에서 배출되는 용융 슬래그로 부터 지오폴리머를 제조하여 알칼리 활성화제의 몰농도, W/S 비(water/ solid ratio), 재령일에 따른 비중과 압축강도 등 물리적 특성을 분석함과 동시에 발포제인 Si 슬러지를 첨가하여 경량화 소재로서의 가능성을 고찰하였다. 특히 경량 지오폴리머의 강도 특성향상을 위하여 복합 활성화제 및 pre-curing 공정을 적용하였다. 단일 활성화제를 사용한 경량 지오폴리머의 압축 강도는 9.5 MPa이었으나, 복합 활성화제로 제조할 경우 2~5배 정도의 압축강도 증진 효과를 나타내었다. 더군다나, pre-curing을 실시한 경량 지오폴리머의 경우, pre-curing하지 않은 시편들에 비해 18~48 % 가량 높은 압축강도 값을 보였다. 본 연구에서 복합 활성화제와 pre-curing 공정의 도입으로 얻어진 경량 지오폴리머의 최고 압축강도는 40 MPa(3일 재령하여 밀도가 $1.83g/cm^3$인 시편)로서 시멘트 콘크리트에 필적하였다. XRD 결정상 분석과 SEM을 이용한 미세구조 분석을 통하여 지오폴리머 표면에서 C-S-H 겔(sodium silicate hydrate gel)의 모상에 꽃봉오리 모양의 zeolite 결정상이 균일하게 분포된 것을 확인할 수 있었다. In this study, a lightweight geopolymer was prepared using by slag discharged from IGCC (Integrated Gasification Combined Cycle) power plant and its physical properties, the density and compressive strength, were analyzed as a function of the concentration of alkali activators, W/S ratio and aging times. Also the possibility of applying it to lightweight materials by adding Si sludge as a foaming agent to the geopolymerg was investigated. In particular, a complex composition of alkali activator and a pre-curing process were applied to improve the strength properties of lightweight geopolymers. While the compressive strength of the lightweight geopolymer using a single activator was 9.5 MPa, the specimen made with a complex composition of alkali activator had compressive strength of 2~5 times higher. In addition, the lightweight geopolymer with pre-curing process showed a compressive strength value of 18~48 % higher than that of specimen made with no precuring process. In this study, by using a complex activator and a pre-curing process. the maximum compressive strength of lightweight geopolymer was obtained as 40 MPa (The specimen was aged for 3 days and had density of $1.83g/cm^3$), which is comparable to cement concrete. By analyzing the crystal phase and microstructure of geopolymers obtained in this study using by XRD and SEM, respectively, it was confirmed that the flower-bud-like zeolite crystal was homogeneously distributed on the surface of the C-S-H gel (sodium silicate hydrate gel) in the geopolymer.

Objective : The objective of this study was to examine the mental health status and its correlates of the marriage-migrant women in Seoul, Korea. Methods : One hundred and seventy marriage-migrant women and one hundred and sixteen married Korean women were recruited from community to complete Symptom Check List-90-Revision (SCL-90-R). Marriage-migrant women were also asked for their socio-demographic factors, acculturative stress, family-relationship stress, and social support. The scores on the SCL-90-R were compared between marriage-migrant women and married Korean women, and the correlates of marriage-migrant women's mental health were investigated. Results : Compared to married Korean women, marriage-migrant women showed lower levels of mental health problems including somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, paranoid ideation, and psychoticism. Longer length of residence in Korea, lower family income, social support, higher acculturation stress, and family relationship stress were all associated with mental health problems of marriage-migrant women Results : Our results suggest that mental health of marriage-migrant women is not necessarily bad, and several factors may affect their mental health. However, further studies are required in a larger representative sample to confirm the study findings.

Objective : The objective of this study was to examine the association between childhood adversity and parenting attitude and neuroticism in adulthood. Methods : Forty nine women were recruited from community and completed Early Trauma Inventory-Short Form (ETI-SF). We compared scores on the Maternal Behavior Research Instrument (MBRI), Neuroticism of NEO Personality Inventory (NEO-PI), and Beck Depression Inventory (BDI) between women with and without childhood adversity. Results : Compared to women without childhood adversity, women with childhood adversity showed more rejecting parenting attitude and higher Depression and Self-Consciousness scores on Neuroticism domain of NEO-PI. Total ETI-SF scores and emotional abuse scores were positively correlated with rejecting attitude scores on the MBRI and BDI scores. Physical abuse scores were positively correlated with rejecting attitude scores. There were positive correlations between rejecting attitude scores on the MBRI, Neuroticism scores on the NEO-PI, and BDI scores. Conclusion : Our results suggest that childhood adversity may have a negative impact on parenting attitude and emotional state in adulthood. For girls who experienced traumatic event, early intervention is needed to prevent the development of neurotic temperament and rejecting parenting in adulthood.
