The chemical structures of perfluorinated compounds(PFCs) have unique properties such as thermal and chemical stability that make them useful components in a wide variety of consumer and industrial products. Two of these PFCs, perfluorooctane sulfonate(PFOS) and perfluorooctanoic acid(PFOA), have received attention and were the most commonly detected. In this study it was analyzed the concentrations of 8 PFCs in samples were collected from drinking water treatment plants for 5 years(2012-2016). PFOS and PFOA were also high concentration and frequency. The mean concentrations of PFOA and PFOS were detected $0.0026-0.0069{\mu}g/L$ and $0.0009-0.0024{\mu}g/L$ in samples from drinking water treatment plants. These were relatively lower or similar compared to PFOS concentrations in Osaka(Japan). In general, these levels are below health-based values set by international authoritative bodies for drinking water. These results will be serve as the first monitoring data for PFCs in drinking water and be useful for characterizing the concentration distribution and management of PFCs in future studies.

본 연구는 다문화가정 자녀의 심리적 적응에 있어 주요하게 작용하는 보호요인에 대해 대해 심층적으로 이해하는 것을 목적으로 하였다. 이를 위해 다문화가정 자녀 16명을 대상으로 심층 인터뷰를 진행하였고 전사된 인터뷰 자료에 대해 분석팀을 구성하여 합의적 질적분석방법(CQR)을 사용하여 분석하고 분석결과에 대해 감수를 받았다. 연구결과, 다문화가정 자녀들의 심리적 적응을 돕는 보호요인은 4개 영역(나에 대한 믿음, 나를 돌보는 방법을 배움, 가까운 사람들의 응원을 받음, 지역사회의 도움)으로 확인되었으며 이와 관련한 13개의 하위 범주가 도출되었다. 이러한 연구 결과를 통해 다문화 가정 자녀에 대한 심리 상담 개입에 있어 함의와 이들을 돕기 위한 다문화 인식 전환과 관련한 교육에 대한 시사점을 제시하고 후속 연구에 대한 제한점을 논의하였다. The purpose of this study is to understand the protective factors for the psychological adaptation of youth from multicultural families. For this, 16 youth from multicultural families were interviewed and the data were analyzed using the consensual qualitative research (CQR) and checked by supervisor. As a result of the study, the protective factors for the psychological adaptation of youth from multicultural families are derived from 4 categories and 13 subfactors. 4 categories included belief in me, learning how to take care of me, being supported by close people, and helping the community. Condering these findings, we discuss the implications of counseling interventions for youth from multicultural families and education for multicultural awareness and present the limitations of subsequent research.

Purpose : This study aims to investigate the effect of instrument-activities daily living training through client-centered home visitation on the cognitive functions, occupational performance, and instrument-activities daily living of elderly at the cognitive support grade(Grade6). Methods : The subject of this study was a 66-year-old woman living in G Metropolitan City, who has been diagnosed with Alzheimer's and mild dementia. The study period was from March 17, 2020 through June 12, 2020, and the A-B-A' design, among the individual case experiments, was adopted as the study design. For the data analysis, descriptive statistic and visual analysis using graph were used for the change of cognitive functions, occupational performance, and instrument-activities daily living. Results : The instrument-activities daily living provided through client-centered home visitation improved the subject's cognitive functions, occupational performance(performance, satisfaction) and instrument-activities daily living. Conclusion : This study showed that daily life training through client-centered home visitation can help elderly people at the cognitive support grade select for themselves the problems of daily life caused by cognitive decline and practice specific action plans, thereby enabling them to maintain and improve the cognitive functions necessary for the performance of activities, such as comprehension, memory, and thinking skills. In addition, it is thought that the activities based on the subject's preferences, performance, and sense of importance assured the subject of feelings of motivation and the possibility of participation, and had a positive effect on the subject’s performance speed and rate. With the above in mind, Instrument-activities daily living client-centered home visitation is proposed as a potential practical intervention program for individuals. It can help elderly people at cognitive support grade to maintain and improve their functions, thereby delaying the progress of their condition to severe dementia.

본 연구에서는 에폭시 수지 갱생 옥내급수관 수돗물에 대해 비스페놀-A 실태조사를 실시하였고, 비스페놀-A가 수돗물 음용에 있어 인체에 미치는 영향을 파악하기 위해 위해성 평가를 실시하였다. 원수 중 비스페놀-A는 50~118 ng/L로 채취된 모든 시료에서 정량한계 10 ng/L 이상으로 검출되었다. 이것은 주변지역의 하수 방류수나 지천에 의한 비스페놀-A 유입에 의한 것으로 판단된다. 정수에서의 비스페놀-A는 불검출되었으며, 고도정수처리 공정에서 모두 제거된 것으로 추정되었다. 응집-침전과정과 오존 및 염소에 의해 산화되어 제거되거나 다른 산화 부산물질로 변화한 것으로 판단된다. 옥내급수관 수돗물의 경우, 에폭시 갱생공사를 실시하지 않은 수돗물 모두에서 비스페놀-A는 검출되지 않았다. 그러나 에폭시 갱생공사를 실시한 옥내급수관 수돗물에서 비스페놀-A가 불검출에서 최대 521 ng/L로 범위로 검출되었으며, 채취된 시료의 68%가 정량한계 이상으로 검출되었다. 검출된 비스페놀-A의 최대값(521 ng/L)에 대한 위해도 지수 산정 결과, 위해도 지수(HQ)는 약 0.004로 수돗물 섭취에 의한 위해판단 기준값 0.1 이하로 나타나 음용에 안전한 것을 확인하였다. In this study, the survey of bisphenol-A in indoor water service pipes rehabilitated with epoxy resin was conducted and the risk assessment was done to investigate the effect on the human health to drink tap water. Bisphenol-A in raw water was detected in a range of 50~118 ng/L in all samples, where the limit of quantification was 10 ng/L. This is caused by inflow of the sewage effluent or the tributaries of the surrounding area containing bisphenol-A. Bisphenol-A was not detected in finished water after the advanced water treatment process. It was achieved by its removal from the processes of flocculation-precipitation and oxidation of ozone and chlorine and by being changed to other by-product materials. For the indoor water service pipe, bisphenol-A was not detected in all cases which was not coated with epoxy resin. However, when epoxy resin is lined within the indoor water service pipe, bisphenol-A was identified at maximum level of 521 ng/L and was detected above the limit of quantitation at 68 percentages of all samples. The Hazard Quotient (HQ) at the maximum level (521 ng/L) of the detected bisphenol-A is 0.004, which is less than the reference value of 0.1 for the tap water intake. Therefore, it is considered that the detected levels of bisphenol-A in this study would be safe to drink tap water.

조효진(Hyojin Cho),손보영(Boyoung Son) 이화여자대학교 교육과학연구소 2021 교육과학연구 Vol.52 No.4

본 연구에서는 대학생들의 SNS 중독경향성에 따라 어떠한 잠재집단이 있는지 탐색하고 어떠한 요인들이 잠재집단을 형성하는 데 영향이 미치는지 확인하고자 하였다. 이를 위하여 서울, 수도권, 충청 지역의 대학생 235명을 대상으로 잠재집단프로파일분석(Conditioanl Latent Profile Anlaysis)을 사용한 SNS 중독경향성의 잠재집단 유형을 확인하였다. 분석결과 3개의 집단으로 분류되었으며 이를 고위험군, 잠재위험군, 저위험군으로 명명하였다. 잠재집단에 따른 다변량 분산분석을 실시하여 각 잠재집단에 따른 특성을 확인한 결과 내현적 자기애, 자기개념 명확성, 외로움, 불안의 모든 변인에서 집단 간 유의미한 차이가 있는 것으로 나타났다. 집단을 분류하는 데 영향을 미치는 요인을 확인한 결과 내현적 자기애, 자기개념 명확성, 외로움 변인이 잠재집단을 구분하는 데 있어 유의한 영향을 미치는 것으로 확인되었으며 불안은 집단구분에 있어 유의한 영향력을 보이지 않는 것으로 나타났다. 이러한 연구결과를 바탕으로 SNS 중독경향성의 예방 및 치료적 개입 및 추후 연구를 위한 제언을 하였다. The purpose of this study was to identify latent groups of college students that become addicted to social networking services (SNS) and to test effects of several variables in determining latent groups. A Latent Profile Analysis (LPA) was utilized to analyze data collected from 235 university students from Seoul and the Chungcheong area in Korea. Results showed that three subgroups within the sample were found to be qualitatively different as they were categorized into the low-risk group, potential-risk group, and high-risk group. The three groups were identified based on the levels of 4 factors of SNS addiction (e.g., control failure, preoccupation and tolerance, avoidance of negative emotions, virtual life orientation and withdrawal). A multivariate variance analysis according to latent groups was conducted to confirm the characteristics of each latent group, indicating significant differences between groups in all variables of covert narcissism, self-concept clarity, loneliness, and anxiety. After identifying the factors affecting the classification of each group, it was found that covert narcissism, self-concept clarity, and loneliness had a significant impact on distinguishing groups. On the other hand, anxiety variables that were found to be highly relevant in prior studies, did not show significant influence in group classification. Based on the results of these studies, we have increased our understanding of the prevention and therapeutic intervention of SNS addiction and made suggestions for further research.

Purpose: This study examined the effects of the fumanet exercise program on the cognitive function and fall down-related physical fitness factor in elderly people. Method: The study period was May 2-June 24, 2016. The participants included 20 elderly persons (control group 10, experimental group 10) who registered at the day-care Center in G. City. Descriptive statistics were used for the analysis of the control and experimental groups` general characteristics. The chi-square and Mann-Whitney U tests were conducted to identify the two groups` general characteristics` and dependent variables` homogeneity. The Wilcoxon signed-rank test was used to compare the pre-and post-intervention cognitive function and fall down-related physical fitness factor, and a Mann-Whitney U test was used to analyze the rate of cognitive function and fall down-related physical fitness factor changes between the groups after the intervention. Result: The participants` fall down-related physical fitness factors (balance, gait, leg strength) increased and memory in the cognitive function sub-area improved in the participants who participated in the fumanet exercise program. The amount of change in gait was significantly different between the control and experimental groups. Conclusion: The fumanet exercise program included gait training using the learn, remember and repeat phased steps. Therefore, this study proposes using the fumanet exercise program to improve the elderly`s cognitive function and physical fitness factor.

This study was to identify the current state and client satisfaction level together with service providers’ recognition and opinion of the community-based occupational therapy services in Gwangju. The survey study was conducted, from January 27th through March 14th in 2011, with 160 clients receiving occupational therapy services at public health centers and their branch offices in Gwangju. The results were as follows. Persons over 65 years old suffering from stroke wanted community based occupational therapy services more than other age groups. The service wanted most was about improving body functions. The client satisfaction was highest for permanent employees among permanent employees, temporary employees, and volunteers. The client satisfaction on facilities and equipments was relatively high except a couple of categories (transportation and new equipments). Service providers perceived that physical facilities and equipments were inadequate; human and financial resources were insufficient; education about professional knowledges and skills were inadequate; and they were in clients’s confidence.
