과불화 화합물(perfluorinated compounds, PFCs)은 열과 산성, 염기 등과 같은 화학적 조건에 높은 안정성을 갖고 있을 뿐만 아니라 발수성, 발유성, 방오성과 제품 친화적인 특징 때문에 다양한 산업소재로 활용되고 있으며, 근래에 이르러서는 대규모로 생산되고 있는 산업제품이다. 그러나 난분해성으로 인하여 환경 내에 잔류하여 전세계적으로 널리 분포하고 있을 뿐만 아니라 인체나 동식물에 이르는 생물체에 이르기까지 오염되어 분포하고 있다. 또한 인체를 비롯한 생물체에 장기적으로 축적될 시 암등을 유발할 가능성이 있다고 보고됨에 따라 이에 대한 관심이 증가하고 있다. 최근 스톡홀름 협약에서 과불화 화합물을 새로운 환경지속성오염물질(persistent organic pollutants, POPs)로 규정함에 따라 이에 대한 분석법의 중요성이 대두되고 있다. 본 연구에서는 다양한 환경 및 생체 시료 내에서 과불화 화합물의 분석법에 대한 연구의 중요성 및 문제점과 더불어 최근 연구 동향을 소개하였다.

CCD photometric observations of the globular cluster (GC), M53 (NGC 5024), are performed using the 1.8 m telescope at the Bohyunsan Optical Astronomy Observatory in Korea on the same nights (2002 April and 2003 May) as the observations of the GC M92 (NGC 6341) reported by Cho and Lee using the same instrumental setup. The data for M53 is reduced using the same method as used for M92 by Cho and Lee, including preprocessing, point-spread function fitting photometry, and standardization etc. Therefore, M53 and M92 are on the same photometric system defined by Landolt, and the photometry of M53 and M92 is tied together as closely as possible. After complete photometric reduction, the V versus B − V , V versus V − I, and V versus B − I color-magnitude diagrams (CMDs) of M53 are produced to derive the relative ages of M53 and M92 and derive the various characteristics of its CMDs in future analysis. From the present analysis, the relative ages of M53 and M92 are derived using the Δ(B − V ) method reported by VandenBerg et al. The relative age of M53 is found to be 1.6 ± 0.85 Gyr younger than that of M92 if the absolute age of M92 is taken to be 14 Gyr. This relative age difference between M53 and M92 causes slight differences in the horizontal-branch morphology of these two GCs.

Objectives : To investigate aggravating and mitigating factors of atopic dermatitis and to utilize the outcome in treatment planning. Methods : The research has a cross-sectional study design. Patients' SCORing Atopic Dermatitis (SCORAD) Index, demographic, physical characteristics, social history, serologic index and skin related instrumental measurements were analyzed with correlation and regression analysis method. Results : 48 patients in total were enrolled in the study. Skin Surface Hydration (SSH) and sex were found to be statistically significant aggravating and mitigating factors. As SSH increased, Total SCORAD (tSCORAD) and Objective SCORAD (oSCORAD) increased as well. As SSH decreased, tSCORAD and oSCORAD decreased as well. Female patient had a higher probability of suffering from severer subjective symptoms than that of male. Age, body mass index (BMI), alcohol consumption and smoking, transepidermal water loss (TEWL), IgE, IL-4, IL-5, IL-6, IFN-γ were found not to be statistically significant. There was no correlation between Subjective SCORAD (sSCORAD) and oSCORAD neither with Eczema Area and Severity Index (EASI). Conclusions : Increasing cutaneous moisture should be included in the treatment plan of atopic dermatitis. More emphasis should be put on alleviating subjective discomforts of female patients than that of male. Establishing separate strategies of managing objective eczema status and subjective discomforts respectively should be considered.

A descriptive study was conducted to describe the content of nursing interventions and incoming telephone calls from the parents whose child was discharged to home or who has planned immunization during the period from March 15, 1995 to November 30, 1995. Detailed notes on 145 telephone calls and 243 nursing interventions were recorded by head nurses on pediatiric nursing units were entered to data collection and content analysis. The results of the study are as follows : 1. Six analysis categories for the records on incoming telephone calls were identified judgement-dependence, dependent -coping, self-initiated coping, support, adjustment and intermediation need. 2. Five analytic categories for the records on telephone interventions were identified : guidance, mediation, facilitating self -care abilities, support, instrumental use. 3. Problems related to physical signs and symptoms, medication, immunization, and vital signs were most often cited as concerns by parents and caregivers. 4. Instruction, suggestion, provision knowledge and information, reassurance related to physical problems, medication, immunization and clinic visits were most often used as an nursing interventions by head nurses on pediatric nursing units. In spite of the fact that the telephone calls were initiated by the parents, dependency of parents during the telephone calls was remarkable. The dependency of parents on judgement and decision making of the pediatric nurses should be understood in terms of the psychosocial content as well as cultural characteristics. Therefore, it is suppested that telephone interventions focus on facilitating the self-care ability of the parents whose children have chronic conditions. The results of this study will be useful as an essential reference in providing effective for children and their families after discharged from the hospital. The results can also be used as reliable data for extended pediatric nursing service in the health care delivery system as well as for the development of telephone intervention service program in responding to the current health care environment.

The present study was initially designed to figure out the general condition of care giving system for the elderly women who need long term care and the level of their depression according to the conditions of care. And This research is intented to present appropriate policy that could help the establishment of supporting system for the fragile elderly women.1 used the data from <2001 National Study on the Needs for the Long-Term Care Elderly> by Korea Health and Population Institute. The results are as follows: First, Two third of all the respondents had serious problems (2-9 activities limits) in Instrumental Daily Living Ability(DAL). Most respondents reported “low” in satisfaction level related to receiving care, meaning the elderly had negative perception for the care from the family. The elderly expected their children to be as the primary care giver and mostly wanted to live with them in the future. Second, The majority of the long term care elderly women haven't used community service facilities very often and said they are not likely going to use the facilities in the future. Third, The respondents reported high in depression level as to lower satisfaction with their children's support, poorer health condition, more reluctant to use service facilities due to the cost, and fewer friends and neighbors resources around them. Therefore I could say that negative factors for the elderly women's psychological health were having unsatisfactory relationship with intimate people, developing physical illness, being in economic difficulties. That is, receiving less help from close family members, shrinking social network, and experiencing economic hardship would have negative effects on elderly women's psychological health. In the basis of these results, I suggest that in the mean time we shouldn't overlook the importance of the private support when we develop the public elderly support system.

기존 설비를 이용하여 최소한의 공정 비용으로 PACS의 특성에 버금가는 개선된 폴리염화알루미늄(IPAC)을 합성하는 기술을 확립하였다. IPAC을 합성하기 전 규산염을 활성화하는 조건을 연구하였고, 수산화알루미늄과 진한 염산을 원료로 하여 활성화된 규산염과 알긴산염을 첨가하여 IPAC을 제조하였다. 제품의 규격, 구조 및 응집특성을 규격시험법, 기기분석법 및 Jar test 장치로 각각 시험연구 하였다. 본 연구에서 합성한 IPAC은 산화 알루미늄 함량이 17%이상 되었으나 원액 보관 시 전혀 침전 생성이 없었으며, 동일 조건에서 PAC 보다 더 큰 floc을 생성하였고 침강속도도 빨랐다. 현재 이 제조기술을 현장에 적용시킨다면 제조설비의 재투자 없이 기존 설비를 이용하되, 추가 반응시약 비용은 기존 공정 상 첨가하는 망초를 넣지 않아도 되기 때문에 거의 원가상승 요인 없이 고효율 무기 고분자응집제를 합성할 수 있었다.
