Recently, utility network is getting more and more complicated and huge. In addition to, demands of power conversion devices which have non-linear switching devices are getting more and more increased. Consequently, according to the non-linear power semiconductor devices, current harmonics are unavoidable. Those current harmonics flow back to utility network and become one of the reasons which make the voltage distortion. On the other hands, voltage sag from sudden increasing loads is also one of the terrible problems inside of utility network. In order to compensate the current harmonics and voltage sag problem, AF(Active Filter) systems could be a good solution method and SMES(Superconducting Magnetic Energy Storage) system is a very good promising source due to the high response time of charge and discharge. Therefore, the combined system of AF and SMES is a wonderful device to compensate both harmonics current and voltage sag. However, unfortunately SMES needs a superconducting magnetic coil. Because of the introduction of superconducting magnetic coil, quench problem caused by unexpected reasons is always existed. In case of discharge operation, quench is a significantly harmful factor according as it decreases the energy capacity of SMES. Therefore, this paper presents a decision method of the specification of the AF-SMES system considering internal fault condition. Especially, authors analyzed the change of the original energy capacity of SMES regarding to the size of resistance caused by quench of superconducting magnetic coil. Finally, based on this simulation, authors manufactured actual Active Filter System using DSP.

Malignant rhabdoid tumor (MRT) was first described as a “rhabdomyosarcomatoid” variant of Wilms tumor, but was later identified as a distinct entity. MRTs are extremely rare and highly aggressive neoplasm with poor outcome, occurring mostly in kidneys and central nervous system, less frequently in extrarenal sites. MRTs are referred to as “congenital” when it is diagnosed at or immediately after birth. There are few reports about congenital disseminated MRT at birth. We report a case of congenital malignant rhabdoid tumor presenting as a soft tissue mass in the right arm at birth although the autopsy revealed the systemic disseminated tumors through the whole body with typical microscopic findings.

노부모의 의존성이 성인자녀와 노부모간 갈등에 미치는 영향

박인아(Park In-A),엄기욱(Um Ki-Wook) 한국노년학회 2007 한국노년학 Vol.27 No.1

본 연구는 노부모의 성인자녀에 대한 의존성이 성인자녀의 노부모와의 갈등에 미치는 영향에 있어서 성인자녀가 회상하는 아동기 피학대경험과 성인자녀의 부모부양의식이 지니는 상호작용효과를 검증하는데 목적이 있다. 또한 이 요인 간 관계를 부모-자녀 간 관계유형, 즉 부모관계, 부자관계, 모자관계, 모녀관계에 따라 차이가 있는지 분석하고자 한다. 분석결과, 노부모와의 갈등에 부모자녀 관계유형과 자녀의 성, 노부모의 의존성, 정서적 피학대 경험, 부양의식 등이 통계적으로 유의미한 영향력을 지니는 것으로 나타났다. 또한 정서적 피학대경험과 도구적 부양의식에 따라 노부모의 의존성이 노부모와의 갈등에 미치는 영향력에 차이가 있는 것으로 나타났다. 또한 노부모의 갈등에 미치는 영향요인과 이들 영향 요인 간 상호작용 효과가 부모자녀 관계유형에 따라 차이가 있는 것으로 나타났다. 따라서 성인자녀와 노부모의 관계를 증진시키기 위해서는 성인자녀에 대한 노부모의 신체적, 경제적, 사회적 의존성을 감소시키기 위한 정책적 개입이 필요할 뿐만 아니라 아동기부터의 적절한 부모-자녀관계를 형성하고, 여전히 한국인의 가치체계에 깊숙이 뿌리내리고 있는 부모부양의식을 유지, 발전시키기 위한 실천적 개입전략과 사회지원체계가 마련되어야 할 것이다. The present study purposed to verify the interaction effect between how old parents' dependency on their adult children affect conflict between the parents and the children, and the adult children's memory of being abused in their childhood and their filial obligation. In addition, we analyzed whether the relation is different according to the type of parent-child relationship, namely, father-son, father-daughter, mother-son and mother-daughter relationships. According to the results of analysis, conflict with old parents was statistically significantly affected by the type of parent-child relationship, children's gender, old parents' dependency, experience of emotional abuse, filial obligation, etc. In addition, there were differences in the effect of old parents' dependency on conflict with old parents according to experience of emotional abuse and instrumental filial obligation. What is more, differences were observed according to the type of parent-child relationship in factors influencing conflict with old parents and interaction effect among the factors. Accordingly, in order to improve the relationship between adult children and their old parents, we need to make political interventions for reducing old parents' physical, economic and social dependency on their adult children, and develop practical intervention strategies and social support systems for promoting desirable parent-child relationship from childhood and for maintaining and enhancing filial obligation deeply rooted in Korean people's value system.

장기요양요원 처우수준분석 및 정부의 책임성 강화 방안

박인아(Park In-a) 한국노인복지학회 2018 노인복지연구 Vol.73 No.3

본 연구의 목적은 노인요양시설 장기요양요원의 처우개선을 위한 정책현황을 분석하고, 향후 정부의 책임성 강화를 위한 정책방향을 제시하는데 있다. 이를 위하여 장기요양서비스의 공공성, 좋은 일자리에 대한 선행연구들 그리고 장기요양요원 처우개선 관련 각종 법률 및 조례내용들을 검토하고, 제1차 및 제2차 장기요양기본계획과 지방자치단체별 장기요양요원 처우개선 사업들을 분석하여 국가 및 지방자치단체의 장기요양요원 처우개선을 위한 정책들을 평가하였다. 그 결과 각종 법률 및 조례 제 · 개정을 통해 노인요양시설 장기요양요원의 급여수준은 향상되었으나, 여전히 보건복지부가 제시한 사회복지시설 종사자 인건비 기준의 1호봉에도 못 미치는 열악한 근로여건에서 일하는 것으로 나타났다. 그리고 지방자치 단체별로 노인요양시설 장기요양요원들의 처우개선을 위한 사업을 수행하고 있으나, 사업대상이 매우 제한적이고 직종, 연령, 근속기간에 따라 차별적으로 적용되는 것으로 나타났다. 결론적으로 장기요양기관 종사자 처우개선을 위한 향후 정책방향으로 첫째, 중앙정부의 사회복지시설 종류별 형평성 확보를 위한 제도 개선 둘째, 공공성 강화를 통한 괜찮은 일자리창출 셋째, 지방자치단체의 장기요양요원 처우개선에 대한 능동적인 역할수행 넷째, 지방자치단체의 장기요양요원 처우개선에 대한 책임성 강화 등을 제시하였다. The purpose of this study is to analyze the current state of policy for the improvement of the treatment of long-term care facilities for the elderly and to present policy direction. To this end, we reviewed previous studies on the publicness and decent work of long-term care services, various laws and ordinances related to the improvement of treatment of long-term care workers, the first and second long-term care basic plans and the long-term care treatment improvement projects by central and local governments. As a result, the level of salaries of long-term care workers in elderly care facilities has been improved through various laws and regulations revision. However, it is still lower than the salaries of workers in social welfare facilities proposed by the Ministry of Health and Welfare. Each local government is carrying out a project to improve the treatment of elderly nursing home long-term care workers, but the scope of the project is very limited. It is differentiated according to the occupation, age, and tenure of the employees. In conclusion, as a policy direction for improving the treatment of long-term care workers, firstly, the government should reorganize the system to secure equity for each type of social welfare facility. Second, create a decent job by strengthening publicity. Third, Actively play a role in improving the treatment of long-term care workers in local governments, and fourth, strengthened accountability for the improvement of treatment of long-term care workers in local governments.

박인아(Park, In A),윤정수(Yoon Jung Soo),박지선(Park, Ji Sun),김정숙(Kim, Jung Suk),나카지마 카즈오(Nakajima, Kazuo) 강원대학교 사회과학연구원 2012 사회과학연구 Vol.51 No.2

본 연구의 목적은 스트레스-평가-대처 이론을 기초로 외국인 여성과 결혼한 한국인 남편의 일상생활에 대한 스트레스가 아내와의 연령차, 아내의 한국어 습득수준, 남편의 월수입 그리고 결혼지속정도와 한국인 남편의 정신건강과의 관계를 매개하는지 검증하는 것이다. 본 연구를 위하여 2009년 C도 여성정책개발원이 다문화가족 한국인 남편을 대상으로 실시한 ‘다문화가족의 일상생활문제에 관한 설문조사’ 자료를 활용하였다. 연구모형의 주요 변수에 모두 응답한 총 242명의 자료를 최종 분석에 사용하였다. 남편의 일상생활 스트레스(아내에 대한 부정적 감정, 가족 및 이웃에 대한 부정적 감정, 경제적 압박감) 인지를 매개변수로 하고 GHQ-12로 측정한 정신건강을 종속변수, 아내와의 연령차, 부인의 한국어 습득상황, 남편의 월수입, 결혼지속기간을 독립변수로 하는 인과관계모형의 데이터에 대한 적합성을 구조방정식모형으로 분석하였다. 분석결과, 남편의 일상생활 스트레스 인지가 남편의 소득수준 및 아내의 한국어 습득수준과 남편의 정신건강과의 관계를 매개하는 것으로 나타났다. 그리고 남편의 일상생활 스트레스 인지의 세 가지 하위요인별 매개효과를 검증한 결과 경제적 압박감 요인만이 소득수준과 정신건강의 관계를 매개하는 것으로 나타났다. 이러한 결과를 통해 다문화가족 한국인 남편의 정신건강에 영향을 미치는 중요한 요인은 국제결혼으로 인한 지역사회 또는 가족이나 아내와의 갈등보다 경제적 어려움임을 확인하였다. The purpose of this study was to verify if the stress perception of Korean husbands who married foreign wives mediate the relationship between age gap with wives, Korean language level of wives, monthly income of husbands, continuance of marriage and mental health of the husbands. For the purpose of this study, ‘Survey on everyday life of multicultural families’ by C District of Korean Women’s Policy Development Institute in 2009 was used. The data from the total 242 people who answered all major variables of research model were used for the final analysis. Stress perception of the husbands in their everyday lives (negative feeling toward their wives, negative feeling toward family and neighbors and financial pressure) was set as media variables, mental health measured by GHQ?12 was set as dependent variable, and the age gap between husband and wife, Korean proficiency of wives, monthly income of husband and period of marriage were set as independent variables. The appropriateness of data of cause and effect relationship model was analyzed with structural equation model. From the analysis, it was found that stress perception of husbands mediated the relationship between husband’s monthly income, wife’s Korean language proficiency and husband’s mental health. When the mediation effect of three sub?factors in stress perception of husbands was reviewed, only financial pressure was proved to mediate the relationship between income level and mental health. Through these results, this study proposed that policy supports should be made to improve their financial power in order to maintain or promote mental health of Korean husbands in multicultural families.

기혼자녀의 노부모와의 관계 불만족이 노부모와의 관계 부적응 행동과 그 영향요인들 간의 관계에서 지니는 매개효과 연구

박인아 ( In A Park ) 한국가족사회복지학회 2012 한국가족복지학 Vol.36 No.-

본 연구는 기혼자녀와 노부모 간 관계 연구로써 상호 성숙하고 친밀한 관계형성을 도모하기 위한 실천방안을 제시하는 데 그 목적이 있다 이를 위하여 스트레스-평가-대처이론을 기반으로 노부모의 성인 기혼자녀에 대한 비지지적 행동과 의존성을 스트레스원으로, 성인 기혼자녀의 건강과 경제수준, 성장기 부모로부터 받은 지지경험과 부모부양의식을 스트레스원에 대한 대처자원으로 설정하였다. 설정된 스트레스원과 대처자원은 노부모와의 관계 불만족을 매개로 노부모와의 관계 부적응 행동에 영향을 미치는 것으로 가정하였다. 연구모형의 데이터 적합성을 검증하기 위해 일개 지역 대학교와 고등학교 학부모를 대상으로 설문조사를 실시하였으며, 280명의 응답 자료를 기초로 Amos 6.0을 이용하여 경로분석을 실시하였다. 분석결과 노부모의 의존성과 비지지적 행동은 노부모와의 관계 불만족에 정적인 영향을 미치며, 성장기 지지경험과 부모부양의식은 관계 불만족에 부적인 영향을 미치는 것으로 확인되었다. 또한 이들 요인들은 노부모와의 관계 불만족을 매개로 노부모와의 관계 부적응 행동에 영향을 미치는 것으로 확인되었다. 본 연구결과를 기초로 노년기 부모-자녀 관계를 향상시키기 위해서는 노부모의 기혼자녀에 대한 비지지적 행동 감소를 위한 노인교육, 성장과정에서부터의 적절한 부모-자녀관계형성을 위한 양육지원프로그램 그리고 의무가 아닌 성숙을 통한 긍정적인 부모부양행동 증진을 위한 자아성장프로그램 등이 필요함을 제시하였다. The purpose of this study is to suggest the necessity of various social welfare programs for establishing a more mature and intimate parent-child relationship. In order to attain the objective, I formulated a research model based on the stress-appraisal-coping theory. Old parents`non supportive behavior and dependency were adopted as the sources of stress, and children`s health and economic level, emotional support from parents early in life, and the consciousness of parent support were adopted as the resources of coping. It was assumed that the adopted sources of stress and resources of coping have a direct effect on children`s dissatisfaction with the old parent. For the statistical verification of the research model, I conducted a questionnaire survey of the parents of university and high school students in one area. In the survey, I collected data from 280 parents. Using the data, path analysis was performed with Amos 6.0 in order to test the statistical validity of the research model. According to the results of the analysis, old parents`s non supportive behavior and their economic and housework dependency were found to increase children`s dissatisfaction with the old parents, and emotional support from parents early in life and their consciousness of parent support were found to decrease their dissatisfaction with the relation. Children`s dissatisfaction with the relation had the effect of mediating between the sources of stress and the resources of coping and the children`s behavior of maladjustment. In conclusion, this study showed that, in order to improve the old parent-child relationship, we need to develop elderly education for reducing old parents` non supportive behavior to their children, programs for establishing a desirable parent-child relationship from the growth process, and programs for self growth that promote positive parent support behavior through children`s maturity.

Purpose: Parenteral nutrition (PN) is a standard supportive care for pediatric patients undergoing hematopoietic stem cell transplantation (HSCT) in Samsung Medical Center. The objective of this study was to identify the factors associated with the length of hospital stay (LOS) in pediatric HSCT patients administrating PN routinely. Methods: This was a retrospective study for 128 pediatric HSCT patients from Aug. 2008 to Dec. 2009. Demographics, nutrition status on the first report in the nutrition support team, calories and nutrients supplied, PN duration, LOS, PN-induced complications, and laboratory data were collected from electronic medical records. Multivariate analyses were conducted to identify factors associated with LOS. Results: The median age of registered patients was 70 months (range 6∼239 months). Twenty-three patients (18.0%) were malnourished moderately to severely when PN was started. Number of autologous HSCT was larger than allogeneic HSCT (87 vs 41). In children undergoing HSCT, LOS was significantly correlated with PN duration (P<0.001) and graft type (P<0.001). Especially, in autologous peripheral blood stem cell transplantation (PBSCT), malnourished patients at the beginning of PN were shown the tendency to increase LOS (P=0.024) and PN duration (P=0.043). Conclusion: In pediatric HSCT patients administrating PN routinely, LOS was associated with a graft type of HSCT and PN duration. Especially for autologous PBSCT patients, the nutrition status at the beginning of PN had the influence on LOS and PN duration. During the peri-HSCT period, careful nutrition monitoring can prevent malnutrition, decrease PN duration, and shorten LOS. (JKSPEN 2011;4(1):1-6)

찰스 우오리넨(Charles Wuorinen)의 작곡기법 연구: “Grand Union”(1973)의 분석33)

박인아 ( In A Park ) 이화여자대학교 음악연구소 2014 이화음악논집 Vol.18 No.2

Charles Wuorinen is one of the most significant American serial composers of the second half of the twentieth-century. In addition to his more than 260 compositions, Wuorinen has also written a practical manual of twelve-tone composition, Simple Composition, which describes and illustrates many of the methods found in his music. His music not only inherits the twelve-tone techniques first exploited by Arnold Schoenberg, Igor Stravinsky, and Milton Babbitt but also develops twelve-tone methods further with his own added concepts. His most significant extension of twelve-tone principles, namely, his time-point nesting method, transfers the intervallic design of an ordered series to the surface rhythms and phrases, and even to the large formal sections. In addition, he employs an aspect of tonality, pitch centricity, yielding hierarchical relationships among pitches. The purpose of this analysis of Wuorinen`s ‘Grand Union’ (1973) is to examine the way the concepts and methods outlined in Simple Composition play out and to explore some of the distinctive features and musical languages achieved exclusively in this work. This paper will display how ‘Grand Union’ embraces contradictory concepts or ideas, such as pitch centricity and serial techniques, by extending tonal and twelve-tone frameworks, creating a balanced layout.

사회복지사의 기관유형, 급여수준, 직업만족이 이직의도에 미치는 영향에 관한 연구

엄기욱(Ki Wook Um),박인아(In A Park) 연세대학교 사회복지연구소 2007 한국사회복지조사연구 Vol.16 No.-

본 연구는 ‘2000년도 한국 사회복지사 실태조사’와 ‘2005년도 전북 사회복지사 실태조사’ 자료를 활용하여 일선 사회복지사의 급여수준과 직업만족을 통제한 상태에서 기관유형에 따라 이직의도에 차이가 있는지 분석하였다. 이를 위해 연도별로 교차분석, F검증, 상관관계분석, 회귀분석을 실시하였다. 분석결과 사회복지사의 성, 연령, 학력 등이 기관유형에 따라 차이가 있는 것으로 나타났다. 구체적으로 2000년도 자료에서는 성과 연령 분포에서, 2005년도 자료에서는 이와 함께 학력분포에서도 차이를 보였다. 둘째, 사회복지사의 급여수준, 이직의도, 직업만족 수준이 기관유형에 따라 차이가 있는 것으로 나타났다. 구체적으로 2000년도에는 급여수준에서, 2005년도에는 급여수준과 이직의도에서 통계적으로 유의미한 차이를 보였다. 마지막으로 사회복지사의 급여수준과 직업만족을 통제한 상태에서 사회복지사가 종사하고 있는 기관유형에 따라 이직의도에 차이가 있는지 분석하기 위하여 회귀분석을 실시하였다. 그 결과 2000년도 자료에서는 성과 직업 만족만이 이직의도에 통계적으로 유의미한 부적인 영향력이 있는 것으로 나타났으나, 2005년도 자료에서는 직업만족과 종사하고 있는 기관유형이 이직의도에 통계적으로 유의미한 영향력이 있는 것으로 나타났다. 결론적으로 현재 일선 사회복지사의 이직의도를 설명함에 있어 사회복지사의 개인특성이나 직무만족 등과 함께 사회복지기관의 특성과 기관유형 간 근무환경의 차이가 주요한 변수로 고려되어야 함을 제시하였다. The present study analyzed social workers’ turnover intention according to institution type with their wage level and job satisfaction controlled, using data from ‘A Survey of Korean Social Workers in 2000’ and ‘A Survey of Jollabuk-do Social Workers in 2005.’ For this analysis, we conducted cross analysis, F test, correlation analysis and regression analysis by year. According to the results of the analysis, first, social workers’ gender, age, academic qualification, etc. were different according to institution type. Specifically, difference was observed in the distribution of gender and age in the data of the year 2000, and in the distribution of gender, age and academic qualification in the data of the year 2005. Second, social workers’ wage level, turnover intention and job satisfaction were different according to institution type. Specifically, statistically significant difference was observed in wage level in 2000, and in wage level and turnover intention in 2005. Lastly, this study conducted regression analysis in order to see if turnover intention was different according to social workers’ institution type with their with their wage level and job satisfaction controlled. According to the results, only gender and job satisfaction had a significant negative effect on turnover intention in the data of the year 2000, and job satisfaction and institution type had a statistically significant effect on turnover intention in the data of the year 2005. In conclusion, the results of this study suggest that, in explaining social workers’ turnover intention, the characteristics of social welfare institution and the difference of working environment among different types of institutions should be taken into account as important variables along with their personal characteristics and job satisfaction.

In order to clarify the effects of acid rain on soil microorganisms, the inpact of acid to soil microorganisms was survyed for 14 weeks using soil microcosms from industrial site A and B, Gaejok mountain, and Daechong lake in Taejeon area. The acid tolerant-microorganisms in natural soil, using culturing method were counted to be 5.8 - $8.0{\times}10^6$CFU/g soil. The number of microorganisms using ATP-biomass analysis for natural soil samples were also analyzed and 2.2 - $2.6{\times}10^9$ cell/g soil in industrial site A and B, Gaejok mountain, and Daechong lake were determined. In soil samples, which were treated with artificial acid rain, the number of acid tolerant microorganisms were counted 2.9 - $5.8{\times}10^5$ and 2.8 - $7.5{\times}10^8$, respectively. Therefore, we conformed that the numver of soil microorganisms were influenced by acid rain. Also, long term acid tolerant microorganisms were identified as Rhodotorula sp. and Pseudomonas sp.
