This study aims to identify experiences of immigration and mental health related characteristics of non U.S.-born adolescents and to examine predictors related to mental distress within a social ecological perspective. Secondary data of 348 non U.S.-born adolescents from the CHIS 2011-2012 Adolescents Survey were used for this study. Impacts of individual, family, school, and community factors on mental distress of non U.S.-born adolescents were examined using hierarchical multiple regression. The average age of the adolescents was 14.5 years (SD = 1.7), and more than half were girls (53.4%). Of the participants, 31.6% were interviewed in a language other than English and 72.7% did not use English at home. Nearly half have been living in the U.S. for over 10 years (48.6%). Approximately 2% had a score of 13 or over indicating serious mental distress. Being interviewed in a language other than English, speaking English at home, having higher levels of school support and neighborhood cohesion, and not being threatened by peers were associated with current lower levels of mental distress in non U.S.-born adolescents. The findings of this study contribute to the literature and theory focusing on impacts of acculturation, school, and neighborhood on mental health of immigrant adolescents. Schools and communities may be the channels to help immigrant adolescents’ acculturation process and ultimately to reduce their mental distress.

Mesoporous silica-based nanoplatforms for the delivery of photodynamic therapy agents

홍석호,최용두 한국약제학회 2018 Journal of Pharmaceutical Investigation Vol.48 No.1

Photodynamic therapy (PDT) is an established method for the treatment of cancer which utilizes light, a photosensitizer (PS), and oxygen. Unfavourable characteristics of most PSs, such as low solubility and tumour specificity have led many researchers to adopt nanoscale drug delivery platforms for use in PDT. Mesoporous silica nanoparticles (MSNs) form a significant part of that effort, due to their ease and controllability of synthesis, ease of loading, availability of diverse surface functionalization, and biocompatibility. Therefore, in this review, we discuss the properties of MSNs as they pertain to their use in PDT and review the latest advances in the field, comparing the different approaches currently being used.

홍석호,어유경,장세정,권은주,김순은 한국노인복지학회 2017 노인복지연구 Vol.72 No.2

As life expectancy increases, information technology (IT) becomes more pervasive in the life of baby boomers. However, baby boomers, who have experienced a short period of rapid industrialization and informatization, may have a different perception of IT development compared to the younger generation. Considering there was no preceding research on the matter, this paper aimed to examine the various perceptions and attitudes toward IT of South Korean baby boomers, This paper used Q Methodology to identify baby boomers' perceptions. An initial questionnaire (Q sample) was composed through literature review and interviews with actual baby boomers. From the initial items, 35 statements on the impact of IT on the biological, psychological, and social aging process, expectation of utilization, and policy suggestion and direction were selected after revision. The researchers recruited 27 participants considering their sex, age, and educational level. From the perspective of successful aging, three types of communication and participation utilizing IT, demanding IT for health promotion, and self-support through information access were deduced as the result of the study. These results suggest practical and policy implications for the application of IT to improve the quality of life in future. 평균수명이 길어지면서 베이비부머들은 IT와 더욱 밀접하게 생활할 것으로 기대된다. 그러나 짧은 기간에 급속한 산업화와 정보화의 과정을 겪는 베이비부머들은 IT 발전에 대하여젊은 세대와는 다르게 인식한다. 베이비부머들의 IT에 대한 인식을 분석한 연구가 전무한 실정에서 본 연구는 한국 베이비부머들의 IT에 대한 다양한 인식과 태도를 살펴보고 유형별특징들을 도출하고자 하였다. IT에 대한 인식 유형을 살펴보기 위해 Q 방법론을 사용하였다. 먼저 다양한 문헌자료와실제 베이비부머들을 대상으로 한 인터뷰를 통해 초기 질문 문항들을 구성하였다. 그중 수정 및 검토를 거쳐 생물학적, 심리적, 그리고 사회적 노화 과정에서 IT의 영향, 활용 기대, 정책 제언과 방향에 대한 35개의 질문 문항을 최종 선정하였다. 베이비부머들을 대상으로성별, 나이, 교육수준을 감안하여 27명의 연구 참여자를 모집하였다. 연구 결과 성공적 노후의 관점에서 베이비부머들이 IT에 대하여 지닌 인식은 IT를 활용한소통과 사회참여형, 건강증진을 위한 IT 요구형, 그리고 정보접근을 통한 자립 희망형의 3가지 유형으로 도출되었다. 연구 결과를 바탕으로 노후 생활의 질을 개선하기 위한 IT 적용의실천적․정책적 함의와 시사점을 제공하였다.

홍석호,계명찬,김종월,이정복,오은정,조동제,최규완,김문규 한국발생생물학회 1999 발생과 생식 Vol.3 No.1

초기배아의 발생과정동안 배아와 모체에서 발현되는 여러 cytokine은 착상을 위한 신호물질로 중요한 역할을 한다. 그 중 interleukin-1 (IL-1)는 배아와 모체간의 상호 신호전달체로서 성공적인 착상을 위한 필수적인 요소로 작용한다고 알려져 있다. 따라서 본 연구에서는 초기배아의 발생과정에 있어서 IL-1 유전자의 역할을 규명하기 위해 생쥐 초기배아에서의 IL-l 유전자의 발현양상을 역전사중합효소연쇄반응을 통해 조사하였고, IL-l 유전자의 To investigate the role of interleukin-l (IL-1) in the embryonic development, in vivo and in vitro expression patterns of IL-1 gene in the preimplantation mouse embryos were examined by RT-PCR, and the effects of explanted mouse ovi-duct and uterine epithelial cells on the expression of IL-1 gene in the pleimplantation mouse embryos were examined by co-culture. IL-1 mRNA was detected in the embryos from 4-cell stage to blastocyst stage in vivo and from morula stage to hatching blastocyst stage in vitro. This transcript was not detected from the GV stage to late 2-cell stage in vivo, and not at the 4-cell and 8-cell stages in vitro. For the co-culture of late 2-cell embryos with the explanted mouse oviduct and uterine epithelial cells, oviducts and uterine epithelial cells were isolated at 48 hour alter the hCG injection. The explanted oviduct and uterine epithelial cells in co-culture groups facilitated the IL-1 gene expression of the mouse embryos in comparison with the control. Taken together these results suggest that the presence of IL-1 plays an important role in preimplantation embryonic development. In addition, the up-regulation of IL-1 gene expression by the explanted oviduct and uterine epithelial cells demonstrates that embryonic expression of IL-l gene may be regulated by the interaction with oviductal and uterine factor (s).

홍석호,계명찬,김종월,이정복,오은정,조동제,최규완,김문규 한국발생생물학회 1999 발생과 생식 Vol.3 No.1

초기배아의 발생과정동안 배아와 모체에서 발현되는 여러 cytokine은 착상을 위한 신호물질로 중요한 역할을 한다. 그 중 interleukin-1$\beta$ (IL-1$\beta$)는 배아와 모체간의 상호 신호전달체로서 성공적인 착상을 위한 필수적인 요소로 작용한다고 알려져 있다. 따라서 본 연구에서는 초기배아의 발생과정에 있어서 IL-1$\beta$ 유전자의 역할을 규명하기 위해 생쥐 초기배아에서의 IL-l$\beta$ 유전자의 발현양상을 역전사중합효소연쇄반응을 통해 조사하였고, IL-l$\beta$ 유전자의 발현에 미치는 수란관과 자궁내막세포의 영향을 밝혀보기 위해 공배양방법을 이용하였다. 그 결과 IL-l$\beta$ in vivo 에서는 4-세포기부터 포배기까지, in vitro에서는 상실배부터 부화중 포배기까지 발현하는 양상을 보였다. 또한 수란관과 자궁내막세포와의 공배양시 대조군과 비교하였을 때 실험군에서 IL-l$\beta$ 유전자의 발현이 촉진되었다. 이러한 결과는 IL-l$\beta$ 의 존재가 착상전 초기배아의 발생에 중요한 역할을 한다는 것을 의미한다. 또한 수란관과 자궁내막세포와의 공배양을 통해 IL-1$\beta$ 유전자의 발현이 수란관과 자궁요소에 의해 조절됨을 확인하였다. To investigate the role of interleukin-l$\beta$ (IL-1$\beta$) in the embryonic development, in vivo and in vitro expression patterns of IL-1$\beta$ gene in the preimplantation mouse embryos were examined by RT-PCR, and the effects of explanted mouse ovi-duct and uterine epithelial cells on the expression of IL-1$\beta$ gene in the pleimplantation mouse embryos were examined by co-culture. IL-1$\beta$ mRNA was detected in the embryos from 4-cell stage to blastocyst stage in vivo and from morula stage to hatching blastocyst stage in vitro.
