본 연구는 초기재혼부부의 결혼생활유지에 자기분화, 부부갈등대처방식에 미치는 효과의 프로그램을 개발하기 위한 사전 연구로서 재혼부부를 대상으로 자기분화, 부부갈등대처방식이 어떤 영향을 미치는지를 연구하고자 한다. 요구도 조사를 위한 포커스 인터뷰 대상은 서울과 경기도 수도권에 사는 부부이고 나이는 30세 이상에서 62세 미만을 선정하였으며, 재혼생활 기간이 1년 이상 6년 미만의 실질적 경험이 있는 부부를 선정하였으며, 부부 한쪽이라도 배우자가 전혼관계를 통해 자녀가 있는 복합가정을 선정하였다. 본 연구는 재혼부부를 대상으로 2017년 4월 4일부터 5월 25일까지 포커스 인터뷰를 실시하였다. 1회기에 100분씩 총 2회기로 개별적 인터뷰를 실시하였다. 포커스 인터뷰를 실시한 결과, 재혼부부들은 원가족에서 형성된 미분화로 역기능적인 습관들이 삼각관계를 형성하고 불안을 더욱 증폭시켰다. 부부가 문제해결을 하는 상황에서 낮은 자아분화 수준으로 표현하며 갈등을 더욱 고조시켰다. 낮은 자기분화수준은 갈등관계에서 자신을 이성과 감정을 분리하지 못하고 감정적으로 반응하기도 하며, 환경에 흡수되는 부정적 갈등 대처방식에도 영향을 미쳤다. 재혼부부에게 가장 취약한 면이 부부간 친밀감이며 유대관계이다. 전혼에서 상처와 부정적 정서로 인해 부부 신뢰감이 취약하였다. 비교적 짧은 재혼기간의 영향과 여러 갈등 요소 인 경제적 갈등, 계부모-친부모의 갈등, 계부모-계자녀의 갈등, 전 배우자와의 갈등, 부부간 잠재적 갈등 등으로 인해 친근한 부부유대관계를 맺지 못하는 어려움을 호소하기도 하였다. 특히 전혼관계의 배우자에 대한 부정적 경험이 남아 있을 경우 현재 배우자를 신뢰하지 못하는 갈등이 영향을 주고 있었다. 그로 인한 부부갈등의 악순환을 초래하는 것으로 나타났다. 본 연구는 재혼부부의 결혼생활유지를 돕는 자기분화, 갈등대처방식에 미치는 통합적 프로그램을 구성하려고 하는 필요성을 시사하는 것이다. 점진적으로 재이혼은 증가하여 부부 및 가족 구성원인 또 다시 부정적 영향을 미치고, 사회문제로 확산될 수 있음을 시사한다. 예방적 차원에서 재혼부부의 결혼생활유지 프로그램에 대한 필요성을 시사한다.

Abstract The stoichiometric and double-ordered perovskite $Sr_2FeMoO_6$ (SFMO) polycrystalline ceramics were fabricated by sintering at above $900^{\circ}C$ in $H_2$(5%)/Ar reductive ambient. SMO polycrystals showed good ferromagnetic properties andmagnetrotesistqnce ratios of about 15 % at 8K and 3 % at room temperature. Amorphous SFMO thin films were deposited on $LaA1O_3$ and $SrTiO_3$ single crystal substrates using rf sputtering method with the SFMO polycrystalline ceramic target. Double-ordered perovskite polycrystalline SFMO thin films were fabricated by solid state crystallization by annealing the deposited amorphous films at above $680^{\circ}C$ in $H_2$(5%)/Ar reductive ambient. SFMO thin films exhibited ferromagnetic behavior. Their magnetroresistance ratios, however, were only 0.3~0.5% at 8K and disappeared with increasing the measuring temperature. This was attributed to the absence of magnetic spin tunneling between grains due to the porous structure and non-stoichiometric composition of the deposited films.

Recently, the number of mature students who apply nursing departments is increasing due to the increase in lifelong learning needs and the high employment rate of nursing jobs. This study aimed to investigate the effect of self-efficacy, satisfaction in major on college adjustment among mature nursing students. Data were collected from October to December, 2021 and a total of 148 mature student participated in this study. The result showed that the self-efficacy was 3.69±0.51, satisfaction in major was 4.07±0.50 and college adjustment was 3.42±0.50. As a result of analyzing factors, grade(β=.20, p=.001), self-efficacy(β=.43, p<.001) and satisfaction in major(β=.37, p<.001) were significant predictors of college adjustment, and the explanatory power was 54%. Mature nursing students are expected to increase in the future, and based on the results of this study, it is suggested that mature nursing students improve their college adjustment by providing intervention programs that can increase self-efficacy and satisfaction in major.

We have carried out a statistical analysis on solar wind dynamic pressure pulses during geomagnetic storms. The Dst index was used to identify 111 geomagnetic storms that occurred in the time interval from 1997 through 2001. We have selected only the events having the minimum Dst value less than -50 nT. In order to identify the pressure impact precisely, we have used the horizontal component data of the magnetic field H (northward) at low latitudes as well as the solar wind pressure data themselves. Our analysis leads to the following results: (1) The enhancement of H due to a pressure pulse tends to be proportional to the magnitude of minimum Dst value; (2) The occurrence frequency of pressure pulses also increases with storm intensity. (3) For about $30\%$ of our storms, the occurrence frequency of pressure pulses is greater than $0.4\#/hr$, implying that to. those storms the pressure pulses occur more frequently than do periodic substorms with an average substorm duration of 2.5 hrs. In order to understand the origin of these pressure pulses, we have first examined responsible storm drivers. It turns out that $65\%$ of the studied storms we driven by coronal mass ejections (CMEs) while others are associated with corotating interaction regions $(6.3\%)$ or Type II bursts $(7.2\%)$. Out of the storms that are driven by CMEs, over $70\%$ show that the main phase interval overlaps with the sheath, namely, the region between CME body and the shock, and with the leading region of a CME. This suggests that the origin of the frequent pressure pulses is often due to density fluctuations in the sheath region and the leading edge of the CME body.

This paper reports a statistical study on the relationship between relativistic electron events(REE), magnetic storms, and substorms. We have used magnetic storm events that occurred between 1996 and 1998, and have classified them into two groups, (i) magnetic storms with REE and (ii) magnetic storms without REE, according to whether or not the magnetic storm is accompanied by REE. Then we have examined the characteristics of substorms that occurred during the main phase of each of the magnetic storms, and compared them between the two groups of the storms. In particular, we have made some quantitative estimations on the intensities of the energetic particle injections and magnetic dipolarizations during the substorm. We find that the injection intensity ratio and the magnetic dipolaization of the storm-time substorms are bigger for substorms with REE than for those without REE.

선천성 대사 이상은 다양한 뇌질환으로 나타낸다. 일반적으로 이 질환들은 하나 또는 둘이상의 대사경로에 대한 생화학적 이상에 원인이 있다. 정상적 생화학적 산물의 결핍이나 비정상적 산물의 축적에 의한 뇌기능 이상에 의해 임상증상이 나타내게 되는데 그 증상은 대개 경기, 경직성, 발육지연 등으로 비특이적이고 영상소견도 마찬가지로 비특이적이다. 대사 이상에 있어서의 신경병변은 일부 뇌백질을 주로 침범하는 경우를 제외하면 대부분 뇌백질을 침범하고 따라서 일반적으로 일차성 뇌백질 질환이 대사성 뇌질환을 일컫는다고 할 수가 있다. 뇌백질 질환은 뇌백질의 구성원중 가장 큰 부분을 차지하는 수초(myelin)를 침범하는 질환을 일컫는다. 중추신경계의 백질은 수초로 싸여있는 축삭(axon)과 선경교세포 (neuroglial cell) 및 혈관 등으로 구성되어 있으며, 이중 대부분을 수초가 차지하고 이 수초로 인하여 정상 뇌백질이 흰색을 나타낸다. 백질내의 신경교세포로는 성상세포 (astrocyte) 와 핍지세포 (oligodendrocyte)가 있으며 신 경교세포의 가장 중요한 기능은 핍지세포에 의한 축삭의 외피화 (ensheathment) 즉, 수초이다. 수초는 핍지세포의 세포질 돌기 (cytoplasmic process)의 일부이며 따라서 수초의 생존과 대사는 핍지세포와 운명을 같이한다. 일반적으로 세포의 생존, 대사와 가장 관련있는 기능은 세포질내에 함유되어 있는 구조물인 소기관(organelle)에 의하여 수행된다. 따라서, 비록 모든 소기관들이 백질 질환을 이르키는데 직접 연관되어 있지는 않더라도 수초의 생존과 대사에는 핍지세포의 소기관들이 매우 중요한 역할을 하게 된다. 세포질내 중요한 소기관으로는 세포 막, 미토콘드리아 (mitochondria), endoplasmic reticulum, Golgi 체, lysosome, peroxisome 그리고 세포질등이 있으며, 이들중에서 lysosomes, peroxisomes, 그리고 미토콘드리아가 특정한 유전성 백질질환에 중요한 역할을 하는 것이 밝혀졌다. 이러한 질환들은 최소한 각 소기관에 의한 질환군으로 분류될 수 있다.

Fibrous dysplasia is a skeletal developmental anomaly of the bone-forming mesenchyme that manifests as a defect in osteoblastic differentiation and maturation. It is a nonhereditary disorder of unknown cause. In fibrous dysplasia, the medullary bone is replaced by fibrous tissue, which appears various imaging findings. It is usually an incidental finding, generally not requiring further investigation. However, fibrous dysplasia may be complicated by pathologic fracture, and rarely by malignant degeneration. We present the image findings of a 44-year-old man who had a chondroblastic osteosarcoma arising from polyostotic fibrous dysplasia in the femur. Evidence of cortical destruction on plain radiography and soft tissue mass in the lesion on MR images suggested a tumor of malignant transformation.

The pseudo spin valve with a structure of Tl/CoFe(t $\AA$)/Cu(30 $\AA$)/NiFe(50 $\AA$)/Ta, showing giant magnetoresistance properties by utilizing coercivity difference between only two soft ferromagnetic layers were produced by d.c UHV magnetron sputtering system. In pseudo spin valve Ta/CoFe/Cu/NiFe/Ta, the magnetic and magnetoresistance properties with change of CoFe thickness were investigated. When the thickness of CoFe was 60 $\AA$, a typical MR curve of pseudo spin valve structure was obtained, showing MR ratio of 3.8 cio and the coercivity difference of 27.4 Oe with a sharp change of hard layer switching. When the CoFe thickness was varied from 20 to 100 $\AA$, coercivity difference between two layers was increased to 40 $\AA$. and decreased to 100 $\AA$ gradually. It is thought the change in coercivity of hard layer was due to the crystallinity and magnetostriction of thin CoFe layer. In order to improve the MR property in CoFe/Cu/NiFe trier layer structure, CoFe layer with change of 2-20 $\AA$ thick was inserted between Cu and NiFe. When the thickness of CoFe was 10 $\AA$, MR ratio was 6.7％, showing excellent MR property. This indicates 50 ％ higher than that of CoFe/Cu/NiFe pseudo spin valve.

Top synthetic spin valves with structure Ta/NiFe/CoFe/Cu/CoFe(P1)/Ru/CoFe(P2)/FeMn/Ta on Si(100) substrate with natural oxide were prepared by dc magnetron sputtering system, and investigated on the magnetoresistance properties and effective exchange bias field. As the thickness of FeMn increased above 150 $\AA$, MR ratio was decreased due to the current shunting effect. As the thickness of free layer decreased below 40$\AA$, MR ratio was reduced rapidly. In case of 40 $\AA$ thick of free layer, spin valve film with a structure Si(100)/Ta(50 $\AA$)/NiFe(27 $\AA$)/CoFe(13 $\AA$)/Cu(26 $\AA$)/CoFe(30 $\AA$)/Ru(7 $\AA$)/CoFe(15 $\AA$)/FeMn(100 $\AA$)/Ta(50 $\AA$) exhibited maximum MR ratio of 7.5 % and an effective exchange bias field of 600 Oe, respectively. Thickness difference dependence in this synthetic spin valve structure on effective exchange field was investigated and interpreted by the analytical method. It should be noted that thickness increase of CoFe(P 1) and decrease of CoFe(P2) in synthetic antiferromagnet leaded to the decrease in effective exchange bias field by experimentally and analytically.

This study was conducted to understand influential factors in determining the advance directive attitudes of elderly patients. Structured survey questionnaires were distributed using a convenience sampling method to the residents of long-term-care facilities. As a result, the attitudes toward advance directives were accounted having 2.84 points, the functions of a family with 2.73 points, and the level of self-efficacy with 3.45 points. Participants who have higher family functions were found to have negative attitudes toward self-efficacy, as the relationship between two variables were in the negative correlation (r =-.324, p<.01). However, participants who have higher self-efficacy showed positive attitudes toward advanced directives as the two variables were in the positive correlation (r =.340, p<.01). This study will contribute to the settlement of the AD in Korea.
