The Immersion Grating Infrared Spectrometer (IGRINS) is an unprecedentedly minimized infrared cross-dispersed echelle spectrograph with a high-resolution and high-sensitivity optical performance. A silicon immersion grating features the instrument for the first time in this field. IGRINS will cover the entire portion of the wavelength range between 1.45 and $2.45{\mu}m$ accessible from the ground in a single exposure with spectral resolution of 40,000. Individual volume phase holographic (VPH) gratings serve as cross-dispersing elements for separate spectrograph arms covering the H and K bands. On the 2.7m Harlan J. Smith telescope at the McDonald Observatory, the slit size is $1^{\prime\prime}{\times}15^{\prime\prime}$. IGRINS has a $0.27^{\prime\prime}$ pixel-1 plate scale on a $2048{\times}2048$ pixel Teledyne Scientific & Imaging HAWAII-2RG detector with SIDECAR ASIC cryogenic controller. The instrument includes four subsystems; a calibration unit, an input relay optics module, a slit-viewing camera, and nearly identical H and K spectrograph modules. The use of a silicon immersion grating and a compact white pupil design allows the spectrograph collimated beam size to be 25mm, which permits the entire cryogenic system to be contained in a moderately sized rectangular vacuum chamber. The fabrication and assembly of the optical and mechanical hardware components were completed in 2013. In this presentation, we describe the major design characteristics of the instrument and the early performance estimated from the first light commissioning at the McDonald Observatory.

This study was done to analyze the trends of research on coping in Korea, to suggest future direction, for research on coping, and ultimately to contribute to an increase in explanation of adaptation. This article reviewed 79 nursing research papers on coping done since 1978 by examining them according to the period of publication or presentation, research design, type of subjects, measurement instruments, research for a degree or not, range of reliability, and association of coping and related variables. The results are as follows : The number of studies on coping increased rapidly from the mid-1980's and decreased slowly from the mid-1990's. The maority of the studies were surveys, comparative studies, or correlational studies. The subects of the 46 studies were healthy people, while those in the remaining studies were patients with a variety of illnesses. Thirth-eight studies on coping were done for master's thesis, three for dissertion, and 38 were not degrees. The Bell and Jalowiec coping scales have not been used since the early 1990's. In contrast, Lazarus and Folkman's W.C.C.L. has been used increasingly since that time. The reliabilities of the coping scale were reported in 37 cases and the Cronbach's alpha coefficients were .71 to .86. All subjects reported using more problem-oriented coping than emotion-oriented coping in short-term or emotion-oriented coping and healthy groups did more long-term coping. It was difficult to describe consistently the relationship between stress and coping according to the type of coping scale or research subjects, but generally moderate relationships were found. This was due to instrumental problems and no consideration of situational context. The subject group who used more short-term coping and less long-term coping reported poorer mental status, and higher scores in burnout and state anxiey than others. That is, the relationship between stress and adaptation increased the power of explanation with intervening the mediating effect of coping. The association of locus of control, mastery, social support, and self-concept with coping showed positive relationships : those of uncertainty and severity in illness with coping showed negativerelationships ; those of state anxiety and depression with short-term coping were positive, and those of self-esteem with long-term coping or problem-oriented coping were negative. There were significant differences in the scores of types of coping according to religion, level of education, and socio-economic status. That is, Presbyterians and Catholics, those with higher education levels and higher socio-economic status used more long-term or problem-oriented coping. On the basis of the above findings the following recommendations are made : 1. There is a need to test the mediating effect of coping variable in order to clarify the concept. 2. Longitudinal studies are needed to determine the patterns of change in coping strategies when stressful events are encountered. 3. It's necessary to develop a reliable and variable measurement tool for coping. 4. There is a need to identify subscales of coping to increase explanation of variance 5. It's necessary to consider personal, situational, and antecedent variables : the characteristics of subject populations, the natures of illness and treatment situations. 6. The power of explanation of studies designed to identify the stress-adaptation process should be increased using the combination model of process-oriented coping and cognitive-structural model.

Social support was found to have buffering effects on the stress response of stroke patients. Especially, the aspects of social support found to be most influential were support from a close, personal source, and overall satisfaction with support. The purpose of this study was to identify the current social network and its characteristics according to gender difference in post-hospitalized stroke patients in Korea. The sample consisted of a convenience sample of 254 patients was recruited 129 men and 125 women who were receiving follow-up care at outpatients clinics. Four aspects of social support-source, quantity, qualify & type- were measured using the modified Social Support Inventory for Stroke Survivors(SSISS) which was developed by McColl & Friedland(1989). Regarding sources of social support, 61.4% reported for 'spouse' as primary caregiver and 31.9%, 'children'. But the distribution of sources of personal support were related to gender; 82.2% of male patients had support from their spouses, while only 40% of female patients reported from 'spouse' but 51.4% from 'children'. Among the children, daughters and sons were more significant support persons than daughters-in-law. The percentages for sources of these significant other support persons were 55.5% for 'children', 8.7% for 'spouse', and 8.3% for 'brothers'. The physician at the outpatient department was the main source of professional support. For the quantify and qualify of social support, the primary caregiver's support was more significant than support by significant other persons. Male patients reported that primary the caregiver' support was greater than that of significant other persons, while female patients perceived significant other persons as giving greater support. Regarding the type of perceived social support, the stroke patients were highly satisfied with the primary caregiver's support in aspects of instrumental, emotional, and informational support. They also reported high satisfaction with support from significant others' support in the aspect of emotional support, while emotional and informational support from professionals was reported as satisfactory. In conclusion, gender difference in the social support network was found in that male patients perceived more support from their spouses, while female patients perceived more support from their children as compared to their spouses.

본 연구는 개인의 주관적 건강상태 판정의 국가간 차이에 주목한다. 주관적 건강상태는 기본적으로 객관적 건강상태에 영향을 받지만, 이를 해석하는 태도나 주관적 신념의 영향을 받아 최종적으로 형성되는 판단이라고 본다. 그러므로 주관적 건강상태의 국가별 차이는 (1) 객관적 건강상태의 차이와 (2) 개인의 태도나 신념체계에 영향을 미치는 사회 문화적 특성의 차이의 결합으로 이해되어야 한다. 2006년에 새로 구축된 '고령화연구패널조사' 자료와 유럽 3개국의 고령자조사 자료를 비교한 결과, 우리나라 고령자가 유럽의 고령자에 비하여 자신의 건강상태를 부정적으로 판정하는 경향이 강하다는 사실을 확인하였다. 본 연구에서는 이러한 사실을 두 가지 방식으로 설명하였다. 첫째, 만성질환 여부나 일상생활 수행능력의 영향을 통제하고 보더라도, 우리나라 고령자의 주관적 건강상태 판정은 독일과 스웨덴, 이태리에 비하여 현저히 부정적이다. 둘째, 만성질환 여부나 일상생활 수행능력 정도와 같은 객관적인 건강상태의 수준은 주관적인 건강상태에 영향을 미치는 것이 분명하지만, 그 정도는 국가마다 다르다. 우리나라에서는 만성질환이 있는 경우, 이로 인하여 주관적 건강상태를 부정적으로 평가하게 되는 정도가 다른 나라보다 심한 것으로 보인다. 그 원인이 무엇인지는 후속연구의 주제로 남긴다.

국내 토양에서 분리한 식물성 병원균인 Alternaria brassicicola SW-3리 항암활성 물질 생산능을 조사하고, 활성물질을 분리 정제하여 구조를 확인하였다. A. brassicicola SW-3는potato dextrose broth를 이용하여 15$^{\circ}C$에서 2주간 진탕 배양한 다음, MTT assay를 실시하여 항암활성을 확인하였으며, 배양여액 중의 항암물질은 ethyl acetate로 추출하고, silica gel column chromatography로 정제하여 무색의 oily product를 얻었다(수율 22mg/m1). 분리된 물질은 물이나 hexane에는 녹지 않고, chloroform, ethyl acetate, ethanol 등에는 잘 녹는 특징을 보였으며, , $IR^{1}$H-NMR, $^{13}$C-NMR 등을 통해 구조를 분석한 결과, 최근에 일본에서 분리되어 항암효과가 있는 것으로 알려진 depudecin과 동일한 물질로 추정되었다. 본 실험에서 분리된 depudecin은 인체간암세포와 mouse 피부암세포에 대한 세포독성을 나타내었으며, 각각의$ IC_50$ 는 $57\mu$g/ml, $69\mu$g/ml로 나타났다. Alternaria brassicicola SW-3에 의해 생산된 물질이 기지의 물질이지만, depudecin은 아직 작용 기작이나 적용범위 등이 밝혀지지 않은 초기 연구 단계에 있는 물질로서, 새로운 항암제로서의 가능성이 매우 높아 이의 유도체를 합성하거나, 다른 항암제와의 혼용에 의해 부작용이 적은 강력한 항암제를 개발하기 위한 선도물질로 활용될 수 있을 것이다.

본 연구의 목적은 각 집단별 노년기 장애발생과 변화에 관련이 있는 영향요인들을 분석하는 것으로 노동연구원의 "한국고령화연구패널(Korea Longitudinal Study of Aging: KLOSA)" 1차(2006년)와 2차(2008년) 기본조사자료를 사용하였다. 연구대상은 65세 이상 남성노인 1,454명(41.7%), 여성노인 2,032명(58.3%)으로 총 3,486명이다. 노년기 장애는 ADL장애와 IADL장애를 측정하였으며 전체노인을 정상노인, 만성질환노인, 치매의심노인, IADL장애노인, ADL장애노인으로 나누어 장애발생과 변화를 분석하였다. 연구결과를 살펴보면 2006년에 장애가 없는 노인들이 2008년에 장애가 발생하는데 영향을 미치는 요인들로는 부상, 시력제한, 인지능력저하, 우울, 건강행태, 사회경제적 특성, 연령 등을 들 수 있다. 부상과 시력으로 인한 일상생활제한 등의 경험은 2006년에 정상노인들이 2년 후 치매의심증상 발생이나 장애발생에 유의미한 영향을 미치고 있으며, 2006년에 인지능력저하를 경험한 노인들은 2년 후 치매의심증상이 나타날 확률이 정상노인의 2배 이상으로 나타났다. 2006년의 만성질환자가 우울증을 갖고 있는 경우는 그렇지 않은 경우에 비해 2년 이후 장애가 발생할 확률이 1.8배 높게 나타났다. 그 외에 흡연과 규칙적 운동의 경험뿐만 아니라 사회경제적 특징들도 비장애노인의 장애발생에 유의미한 영향을 미치고 있음을 알 수 있다. 2006년에 장애를 이미 갖고 있는 장애노인들의 2년 후 장애수준변화에서는 ADL장애노인의 경우는 유의미한 변수가 나타나지 않았으나 IADL장애노인의 경우는 도구적 지지를 적게 받을수록, 연령이 증가할수록 장애수준이 악화되는 가능성이 높게 나타났다. 본 연구결과를 바탕으로 노년기장애발생을 예방하고, 장애악화를 지연시키기 위해서 다양한 수준의 개입이 필요함을 제시하고 있다.

본 연구에서는 국내 폐광산에 이용될 채움재의 위해성 평가작업을 위한 전략과 방법론을 개념적 측면에서 제시하였다. 채움재는 석탄발전소 비산재와 고형재로 구성되어 있으며 탄산염 등 위해도가 적은 물질이 대부분을 차지하지만 일부 중금속 성분이 포함되어 있어서 이에 대한 위해성 평가가 요구된다. 위해성 평가는 주로 인체내 발암 및 비발암성 유발 가능성을 정량화하는 것이 목적이며, 본 연구의 경우 국내/외 토양 및 광해 위해성평가 기법을 참조 할 수 있을 것으로 판단된다. 이 때 독성이나 분배계수 등 항목별 주요 은 인자 값은 국내 토양위해성평가 가이드라인에서 제시하는 수치를 주로 이용할 수 있다. 오염도에 대한 정확한 위해 성평가는 현장답사와 실측 등을 통한 노력과 시간이 요구된다. 또한 채움재내 중금속 성분 및 농도가 매우 다양하고 반응이 복잡하여 이를 전부 상세하게 평가한다는 것은 비효율적이다. 따라서, 효과적인 위해성 평가를 위하여 일단 문헌 자료와 채움재 시료특성분석결과를 이용한 예비위해성평가를 먼저 실시하고, 그 이후 상세 위해성 평가에서 예비위해성평가에서 선정된 유의 사항을 중점적으로 다뤄야 할 것으로 생각된다. 이를 위해서는 신뢰성 있는 시료분석기법과 노출경로 및 관련 메커니즘에 대한 충분한 이해가 선행되어야 한다.

Objectives: The objective of this study is to understand the factors having effects on the view of marriage of female university students, and also to present the reference data for establishing the measures for having the positive view of marriage of female university students. Methods: An online survey was conducted targeting total 254 female university students of two universities in Gyeonggi region, from October 1 st to November 13th 2020. The results of this study are as follows. Results: First, to the question related to the intent to marry, total 70% of them responded that they had intent to marry. In the time of marriage, they said they would marry when getting financially stable. The 30% of subjects said that they would choose non-marriage because they wanted to continuously enjoy free life and they did not want to bear burden related to childbirth and child-rearing. Second, in the results of analyzing differences in the view of marriage according to the general characteristics, the students with intent to marry showed the higher romantic view of marriage, instrumental view of marriage, and exclusive view of marriage than the students without intent to marry, which showed significant differences. Third, the view of marriage were the factors having the greatest effects on the intent to marry of female university students. Conclusion: Based on such results of this study, it would be necessary to focus on the policies that could positively change the view of marriage of female university students. It would be needed to establish the social·institutional support measures for work-life balance by reducing women's burden of childbirth and child-rearing. To the question about the time of marriage, the most subjects responded that they would do so when the economic ability and stable job were equipped. Thus, there should be the systematic youth employment support system that could help the students to quickly and stably enter society and to become financially independent after graduation. Also, for the formation of positive family relation, it would be necessary to develop·operate the educational programs for forming positive family relation and desirable communication methods for each subject(spouse, parents, children, siblings, and etc.).
