This study was conducted to assess the attitude of pregnant women toward delivery method, understanding of the reason for determining her own delivery method, participation in decision-making process and satisfaction with delivery method after labor. Study subjects were 693 pregnant women who had visited obstetric clinic for prenatal care in the last month of pregnancy in one general hospital and one obstetrics-gynecology specialty hospital in Taegu city from February 1 to March 31 in 1998. A questionnaire was administered before and after labor and a telephone interview was done one month after labor. Proportion of women who had health education and/or counselling about delivery method during prenatal care was 24.0% and this proportion was higher for women who had previous c-section(35.5%) than others. Women thought vaginal delivery is better than c-section for both maternal and baby's health regardless of previous delivery method. About 90% of primipara and multiparous women who had previous vaginal delivery wanted vaginal delivery for the index birth, while 85.6% of multiparous women who had previous c-section wanted repeat c-section. Reasons for choosing c-section in pregnant women who preferred vaginal delivery before labor were recommendation of doctors(81.9%), recommendation of husband (0.8%), agreement between doctor and pregnant woman(4.7%), and mother's demand (12.6%). Reasons for choosing vaginal delivery were mother's demand(30.6%) and no indication for c-section(67.2%). Reasons for choosing c-section in pregnant women who preferred c-section before labor were recommendation of doctors(76.2%), mother's demand(20.0%), recommendation of husband(1.3%), and agreement between doctor and pregnant woman(2.5%). Of the pregnant women who had c-section, by doctor's recommendation, the proportion of women who had heard detailed explanation about reason for c-section by doctor was 55.1%. Mother's statement about the reason for c-section was consistent with the medical record in 75.9% . However, over 5% points disparities were shown between mother's statement and medical record in cases of the repeat c-section and mother's demand. In primipara and multiparous women who had previous vaginal delivery, the delivery method for index birth had statistically significant association with the preference of delivery method before labor(p<0.05). All of the women who had previous c-section had delivered the index baby by c-section. Among mothers who had delivered the index baby vaginally, 84.9% of them were satisfied with their delivery method immediately after labor and 85.1% at 1 month after labor. However, mothers who had c-section stated that they are satisfied with c-section in 44.6% immediately after labor and 42.0% at 1 month after labor. Preferred delivery method for the next birth had statistically significant association with delivery method for the index birth both immediately after labor and in 1 month after labor. The proportion of mothers who prefer vaginal delivery for the next birth increased with the degree of satisfaction with the vaginal delivery for the index birth but the proportion of mothers who prefer c-section for the next birth was high and they did not change significantly with the degree of satisfaction with the c-section for the index birth. These results suggest that the current high technology-based, physician-centered prenatal and partritional cares need to be reoriented to the basic preventive and promotive technology-based, and mother-fetus-centered care. It is also suggested that active involvement of pregnant woman in decision-making process for the delivery method will increase the rate of vaginal birth after c-section and decrease c-section rate and improve the degree of maternal satisfaction after delivery. 본 연구는 임산부들의 분만전 분만방법에 대한 태도, 자신의 분만방법에 대한 이해 및 개입 정도, 분만후 분만방법에 대한 만족도 등을 평가하기 위하여 대구시내 1개 대학병원과 1개 산부인과 전문병원에서 산전진찰을 목적으로 내원한 임신 36주 이상의 임부 693명을 대상으로 분만전, 분만직후, 분만 1개월 후 3차례에 걸쳐 설문조사를 시행하였다. 임신기간 중 분만방법에 대한 교육이나 상담을 받은 임부는 24.0%였으며, 교육이나 상담을 받은 임부의 비율은 이전에 제왕절개분만을 한 임부에서 유의하게 높았다(p<0.05). 초산부, 자연분만을 했던 경산부, 제왕절개분만을 했던 경산부 모두 자연분만이 엄마나 아기의 건강에 더 좋다고 대답하였으나, 제왕절개분만을 했던 임부들 중 9.2%는 제왕절개분만이 아기의 건강에 더 좋다고 생각하였다. 분만전 선호하는 분만방법은 초산부와 자연분만을 했던 경산부는 90% 이상이 자연분만을 원했으나, 제왕절개분만을 했던 경산부는 85.6%가 제왕절개분만을 선호하였다. 분만전 자연분만을 선호하였던 임부들이 제왕절개 분만을 결정하게 된 이유는 의사의 권유가 81.9%, 남편의 권유가 0.8%, 충분히 상담후 결정한 경우가 4.7%, 산모가 원하여 12.6%였으며, 자연분만을 결정하게 된 이유는 대부분이 제왕절개분만을 할 특별한 사유가 없었거나(67.2%) 산모가 원한 것(30.6%)으로 나타났다. 제왕절개분만을 원했던 임부들의 제왕절개분만을 결정하게 된 이유는 의사의 권유가 76.2%, 산모가 원한 경우 20.0%, 남편의 권유가 1.3%, 의사와 충분히 상담후 결정한 경우는 2.5%였다. 의사의 권유로 제왕절개분만한 산모가 수술 이유에 대해 충분히 설명을 들은 경우는 55.1%였다. 제왕절개분만을 한 산모들의 수술 이유에 대한 의무기록과 산모 대답간의 일치율은 75.9%였으며, 반복 제왕절개분만일 경우와 산모가 원한 경우에 5% point 이상 응답을 차이가 났다. 초산부와 자연분만을 했던 경산부의 산전에 선호한 분만방법은 실제 분만방법과 유의한 관련성을 보였고(p<0.05), 제왕절개분만을 했던 경산부들은 선호도에 관계없이 100% 제왕절개분만을 하였다. 분만후 분만 방법별 자신의 분만방법에 만족하는 비율은 자연분만한 산모는 분만직후 84.9%, 분만 1개월 후 85.1%였으나 제왕절개분만을 한 산모는 분만직후 44.7%, 분만 1개월 후 42.0%로 나타냈다(p<0.05). 분만후 분만방법에 대한 선호도는 분만직후, 분만 1개월 후 모두 분만방법과 유의한 관계를 보였고, 각 시기별 분만방법에 대한 만족도와는 자연분만을 한 산모들은 자신의 분만방법에 만족할수록 자연분만을 선호하였지만, 제왕절개분만을 한 산모들은 만족 정도와 관계없이 제왕절개분만에 대한 선호도가 높았다. 이러한 결과는 그동안의 의사 중심의 전문적인 기술위주의 산전관리와 분만관리에서 기본적인 예방 및 건강증진 위주의 임부와 태아 중심 관리로의 방향 전환이 필요하며, 임부의 임신과 분만에 관한 적극적인 교육 및 상담이 필요하며, 분만방법 결정과정에 임부가 적극적으로 참여함으로써 제왕절개 분만율을 낮추고 제왕절개술후의 자연분만을 유도할 수 있을 뿐만 아니라 분만후 분만방법에 대한 만족도도 향상시킬 수 있음을 시사한다.

The purpose of this research is to identify the ideal environment in which to maintain the effects of play therapy and to use this as a framework to seek the best pastoral counseling practice. This study is conducted based on one investigator’s experience in this area. Through unbiased and in depth counseling, the client’s experiences are studied using a phenomenological psychological approach and by comparing the various forms and effects of parent counseling. Twelve people consisting of parents and their children took part in this study. Based on various works in the field, the participants were divided into three different groups dependent on the situation of the participant and investigator. Group 1 consisted only of play thrapy without parent counseling (exclusive play therapy). Group 2consisted of traditional play therapy followed by fifteen minute parent counseling with follow ups with the parents for instructions and training purposes once every month or two months (play therapy with every 1, 2months parental counseling). Group 3 consisted of regular separate parent counseling sessions in addition to play therapy (play therapy with regular parental counseling). The effectiveness of counseling was not maintained in children from group 1. Although the effect of counseling was maintained in approximately 50 percent of children from group 2, they were lacking in self confidence and appeared anxious. Interestingly, the effect of treatment in children from group 3 not only lasted at least three years but the children are also showing continuous improvement over time. The reasons for the success of group 3 are the hypothesized to be the following: a) with the improvements in understanding of their children and in nurturing techniques, the parents gained confidence b) the parents gained better insight of themselves and accordingly resolved their own psychological issues c) with the improvements of their own personal relationships, of their peace of mind, and the newly found hope in life, the parents were able to provide positive nurturing environments for their children d) parents themselves became the therapist and problem–solvers for their family after the counseling. Strikingly, the importance of parent counseling are observed in all 3 groups. In conclusion, this study suggests that because the parent provides the most influential environment to the child, positive changes in the parent will allow the maintenance and improvement of the effect of play therapy. For discussion purposes, I have used the updated ‘critical correlational method’ by Don Browning. Based on these results, the researcher suggested that the pastoral counseling model of parent counseling to be named ‘New Wineskin Model.’ One must empty all aspects of idol worship, guilt, fear and wound and be filled with new knowledge, understanding, love, acceptance, forgiveness, positivity,thankfulness, self–love and self–realization. Extending the concept of neighbors will allow one to develop further interest and love of the community. Self–centeredness will extend to self-transcendence. Finally, we will be able to witness the voluntary practice of “love your neighbor as yourself.” In this manner, parent counseling has not only resulted in solving their own personal problems but it has allowed fundamental changes in their self–being.

1934년 한의학 부흥 논쟁: 한의학 정체성의 ‘근대적’ 재구성

전혜리 한국과학사학회 2011 한국과학사학회지 Vol.33 No.1

In 1934, there was a severe controversy between advocates of traditional medicine in Korea and a biomedicine-trained doctor. Through the debate, the advocates of Korean medicine attempted to “modernize” their field and to secure an independent status that would guarantee the institutionalization of Korean medicine. Pursuing their independent standing, however, required the advocates to find a rationale that Korean medicine should be separated from Western medicine. They emphasized that there existed fundamental differences in both theory and practice between the two kinds of medicine. Cho Hunyoung (趙憲泳, 1900-1988), for example, successfully showed that Korean medicine was not only distinct from Western medicine but also complementary to it. In so doing, he made a parallel comparison between the two so that Korean medicine could be seen as a part of the “modern” medicine rather than of the “traditional” one. After the debate, practitioners of Korean medicine broadly accepted the newly established identity of Korean medicine as a counterpart of Western medicine. The advocates founded a journal, Oriental medicine (東洋醫藥), and promoted it as an independent space for the research of Korean Medicine. However, there was a limitation in the project for the self-reliance of Korean Medicine, since the “modernization” of Korean Medicine was achieved by making it as “the other” of Western medicine. Korean medicine couldn’t be entirely independent from the standards of Western medicine.

Corrosion protection by epoxy coating containing multi-walled carbon nanotubes

전혜리,손민영,박진환 한국공업화학회 2013 Journal of Industrial and Engineering Chemistry Vol.19 No.3

Epoxy coatings that contained multiwalled carbon nanotubes (MWCNTs) were prepared. Further, the effect of the MWCNTs on the hydrophobicity and water transport behavior, and hence, on corrosion resistance provided by the epoxy coating were examined using hygrothermal cyclic tests and electrochemical impedance spectroscopy (EIS). The water transport behavior of epoxy coatings with higher MWCNT content decreased to a larger extent for coatings with higher surface hydrophobicity. The corrosion protection of carbon steel coated with epoxy coating that contained MWCNTs correlated well with water transport behavior and hydrophobicity.

전혜리,최수현,임지영,박희진,홍은주,손부순,Jeon, Hye-Li,Choi, Su-Hyeon,Im, Ji-Young,Park, Hee-Jin,Hong, Eun-Ju,Son, Bu-Soon 한국환경보건학회 2012 한국환경보건학회지 Vol.38 No.3

Objectives: The changes in atmospheric $PM_{2.5}$ concentrations were extensively studied in one metropolitan city (Incheon), two small and medium sized cities (Gunsan, Cheonan), and a rural area (Gosan in Jeju). The concentrations of heavy metals (Cr, Mn, Fe, Ni, Cu, Zn, Al, Pb) and the component features of $PM_{2.5}$ were determined for these areas. Methods: This study sampled $PM_{2.5}$ at the designated locations in the metropolitan (Incheon), small and medium sized cities (Gunsan in Jeonbuk and Cheonan in Chungnam), and rural area (Gosan in Jeju) to investigate concentrations with a sampling device (Sequential sampler, APM Eng., Korea). Sampling was undertaken over months, from June 26 to November 26, 2009. Sampling was conducted a total of 44 times, with routine sampling at intervals of six days (24 total times) and intensive sampling (20 total times) during the summer and fall. Mass concentration of $PM_{2.5}$ was evaluated and the concentrations of heavy metals (Cr, Mn, Fe, Ni, Cu, Zn, Al, Pb) were analyzed. Results: The geometric average of concentrations of $PM_{2.5}$ per district was $35.289{\mu}g/m^3$ for Cheonan, $29.955{\mu}g/m^3$ for Incheon, $24.119{\mu}g/m^3$ for Gunsan, and $18.773{\mu}g/m^3$ for Jeju, respectively. The average concentration of $PM_{2.5}$ in Cheonan was the highest. The seasonal concentration distributions per district showed Cheonan $33.387{\mu}g/m^3$, Incheon at $31.550{\mu}g/m^3$, Gunsan $22.900{\mu}g/m^3$, and Jeju $18.900{\mu}g/m^3$ in the summer. For the autumn, the concentrations were $36.873{\mu}g/m^3$ in Cheonan, $28.625{\mu}g/m^3$ in Incheon, $25.227{\mu}g/m^3$ in Gunsan, and $18.667{\mu}g/m^3$ in Jeju. According to the collected data, the concentration showed a tendency to rise during the autumn in all of these regions with the exception of Incheon. For heavy metal distribution per district, Fe showed an elevated concentration during the summer while high concentrations of Pb and Zn occurred during the autumn. Conclusion: These results demonstrated that atmospheric factors affected the concentrations of heavy metals. The results of this study could be used as foundational data for setting environmental air standards focusing on a $PM_{2.5}$ receptor.

대기 중 PM2.5의 이온성분 특성

전혜리,최수현,조태진,홍성철,이종대,손부순 대한보건협회 2011 대한보건협회 보건종합학술대회 Vol.2011 No.-

[연구배경] 현재 미세먼지가 PM10보다 PM2.5에서 건강에 크게 영향을 줄 수 있음에도 불구하고 우리나라의 경우 지속적인 연구를 통한 자료 축적이 극히 적어, 향후 미세먼지 저감 및 대책을 수립하기 위해서는 대기 중 일부오염 물질의 측정만으로 정확한 현황 파악 및 저감대책을 수립하기 어려운 실정이다. [연구목적] 본 연구의 목적은 천안지역의 PM2.5 내 이온성분에 대한 자료를 분석하여, 농도수준 및 성분 특성을 파악하고 PM2.5에 대한 지역별 기준 설정 및 관리대책을 수립하는데 필요한 기초자료를 제공하고자 한다. [연구방법] 본 연구는 2009년 6월부터 11월까지 천안지역을 대상으로 연속시료채취장비인 PMS - 103을 사용하여 채취된 테프론 필터를 Ion Chromatography(IC)을 이용하여 대기 중 PM2.5 내 이온성분(NH4+, Na+, K+, Ca2+, Mg2+, SO42-, NO3-, Cl-, non - sea salt - Ca2+, non -sea salt - SO42-)을 분석하였다. [연구결과] 천안지역 이온성분들의 평균 농도는 non - SO42-(7.240ug/m3) >NH4+(3.221ug/m3) >NO3-(2.808ug/m3) >K+(0.444ug/m3) >Cl-(0.241ug/m3) >Na+(0.228 ug/m3) > nss - Ca2+(0.101ug/m3) >Mg2+(0.032ug/m3)의 순으로 높게 나타났다. 이온성분 중 가장 많은 부분을 차지하고 있는 SO42-는 여름철과 가을철에 각각 8.791ug/m3, 6.051ug/m3로 나타나 여름철에 높은 농도를 나타내었으며, 해염기원의 성분인 Na+, Cl-의 경우 여름철(각각 0.156ug/m3, 0.146ug/m3)보다는 가을철(0.287ug/m3, 0.320ug/m3)에 높은 농도를 나타내었다. NO3-의 계절별 평균 농도는 여름철과 가을철에 각각 1.372ug/m3, 4.006ug/m3로 SO42-와는 반대로 가을철에 놓은 농도를 나타내었다.
