본 연구의 목적은 2001년과 2011년에 이루어진 조사결과를 비교하여 한국 사회복지사들의 윤리적 신념과 윤리적 상황에 대한 경험이 어떻게 변화되었는지 알아보는 것이다. 클라이언트와의 “이중관계”에 대한 신념과 경험에 초점을 두고, 현재와 과거 사회복지사들의 윤리적 신념과 경험의 차이를 살펴보고, 인구사회학적 특성 및 조직의 특성에 따른 사회복지사들의 신념과 경험의 차이의 양상이 어떻게 달라졌는지 알아보았다. 이를 위하여 현직 사회복지사들을 대상으로 실시된 설문조사 256부를 분석하였고, 2001년 발표된 유사한 설계의 연구 결과와 비교하였다. 연구 결과, 현재의 사회복지사들은 10년 전보다 신념이나 경험에 있어 더 엄격한 기준을 갖고 있는 것으로 나타났으나, 이중관계의 내용에 따라 상대적으로 더 허용적인 측면도 나타났다. 인구사회학적 특성 및 소속된 기관의 특성에 따른 사회복지사들의 윤리적 신념과 경험에서도 성별이나 교육수준, 기관형태 등에 있어 차이가 있다는 사실은 동일하였으나 차이의 양상은 다소 다르게 나타났다. 이와 같은 결과를 토대로 향후 사회복지실천현장과 윤리교육에 대한 함의를 논의하였다. The purpose of this article was to study how social workers’ belief and behaviors with respect to ethical issues have changed during the past decade by comparing the results of studies carried out in 2001 and 2011, respectively. Focusing on dual relationship with clients, this article reviewed how social workers’ belief and behaviors towards ethical issues have changed over the changing socio-demographic characteristics and varying properties of the organizations for which the workers provide services. To accomplish this purpose, we surveyed 356 social workers while the results of the survey was subjected to a comparative review with another research performed 10 years ago under a similar approach. Widely acknowledged during the survey was that the social workers appeared to have more rigid ethical standards compared to 10 years ago; however, they tended to be more permissive in certain issues such as bartering relationship and private relationship. In addition, according to the survey, belief and behaviors of social workers towards ethical issues varied depending upon their gender, education level, and the properties of the organization as seen in the survey in 2001 while the modalities have changed over the decade. Based on these results, it is suggested that the curriculum of social work ethics should be revised to reflect present field situation and inspire ethical sensitivity.

본 연구의 목적은 개인, 가족, 학교 요인이 농촌 청소년의 다문화수용성에 미치는 영향을 알아보고, 이러한 영향관계에 다문화 미디어능력이 어떤 매개효과를 보이는지를 살펴보고자 하는 것이다. 이를 위해 자기효능감, 부모의 다문화 양육태도, 학교의 다문화 교육경험을 독립변수로, 다문화 미디어능력을 매개변수로 하여 구조방정식 모형 분석을 실시하였다. 농촌 소재 중·고등학교에 재학 중인 청소년 469명을 대상으로 분석한 결과, 자기효능감, 부모의 다문화 양육태도, 학교의 다문화 교육경험은 모두 다문화수용성에 유의미한 영향을 미치는 것으로 나타났으며, 다문화 미디어능력도 다문화수용성에 직접적인 영향을 미쳤다. 다문화 미디어능력의 매개효과는 통계적으로 유의미하지 않았으나, 부모의 다문화 양육태도가 다문화 미디어능력에 유의미한 영향을 미치는 것으로 확인되었다. 이러한 연구 결과를 토대로, 농촌 청소년의 다문화수용성향상을 위해서는 청소년 개인의 자기효능감 증진과 함께 부모의 양육태도에 대한 지도와 학교에서의 다문화 교육경험이 종합적으로 제공되어야 하며, 다문화 관련 미디어를 비판적으로 이해하는 능력을 배양해야 한다는 실천적 방안을 제시하였다. The purpose of this article is to study how personal, family and school factors relate to rural adolescents` multicultural acceptability and to investigate the effect of media interpreting ability as mediating factor to this relationship. To achieve this purpose, this study conducted a structural equation modeling analysis using self-efficiency, parenting attitude to multiculture and multicultural learning experiences in school as independent variables. We surveyed 480 adolescents who are in middle and high schools in rural area and used 469 answers for the analysis. The findings of this study are as follows. Self-efficiency, parenting attitude to multiculture, multicultural experiences in school have a significant effect on rural adolescents` multicultural acceptability. Media interpreting ability about multicultural contents also directly affects on multicultural acceptability while it does not have a significant mediating effect on relationship between other factors and multicultural acceptability. This result means it is necessary to provide a comprehensive service for their families and schools as well as themselves in order to increase rural adolescents` multicultural acceptability. Moreover, parents` guidance is important how their children perceive and accept multicultural contents of public media.

Oxidative modification of cellular proteins and lipids may play a role in the development of diabetic complications. Diabetic cardiomyopathy has been suggested to be caused by the intracellular $Ca^{2+}$ overload in the myocardium, which is partly due to the defect of calcium transport of the cardiac sarcoplasmic reticulum (SR). In the present study, the possible mechanism of the functional defect of cardiac SR in diabetic rats was studied. Both of the maximal $Ca^{2+}$ uptake and the affinity for $Ca^{2+}$ were decreased in the diabetic rat SR in comparison with the control. To investigate whether the functional defect of the cardiac SR in streptozotocin-induced diabetic rat is associated with the oxidative changes of cardiac SR proteins, the carbonyl group content and glycohemoglobin levels were determined. The increase in carbonyl group content of cardiac SR (2.30 nmols/mg protein, DM; 1.78, control) and in glycohemoglobin level $(13{\sim}17%,\;DM;\;3{\sim}5%,\;control)$ were observed in the diabetics. The extent of increase in calcium transport by phospholamban phosphorylation was greater in the diabetic cardiac SR membranes than that in the control. The phosphorylation levels of phospholamban, as determined by SDS-PAGE and autoradiography with $[{\gamma}^{32}P]ATP$, were increased in diabetic cardiac SR. These results suggest that the impaired cardiac SR function in diabetic rat could be a consequence of the less-phosphorylation of phospholamban in the basal state, which is partly due to the depleted norepinephrine stores in the heart. Furthermore, the oxidative damages in cardiac SR membranes might be one of the additional factors leading to the diabetic cardiomyopathy. 스트렙토조토신으로 당뇨를 유발시킨 쥐의 심근 근장그물에서 칼슘이동이 저하됨을 볼 수 있었다. 칼슘이동의 저하는 최대칼슘 uptake의 감소와 칼슘에 대한 affinity의 감소로 나타났다. 이러한 심근 근장그물의 기능저하가 나타나는 작용기전이 심근 근장그물 단백의 산화성 손상과 관계가 있는지를 살펴보았다. 당뇨쥐에서는 glycohemoglobin과 carbonyl group의 양이 현저히 증가됨을 볼 수 있었다. 한편으로 cyclic AMP 의존성 protein kinase의 catalytic subunit에 의한 phospholamban 인산화에 의해 심근 근장고물 칼슘이동의 증가를 보였고, 이 증가는 대조군에 비하여 당뇨군에서 훨씬 현저하게 나타났다. SDS-polyacrylamide를 이용한 전기영동후 autoradiogram을 통하여 확인한 phospholamban 인산화는 당뇨군에서 진한 band로 나타남이 확인되었다. 이상의 결과로 미루어 당뇨군의 심근 근장그물 기능저하는, 기초상태에서 아마도 심근내 저하된 norephinephrine 양으로 인하여 phospholamban 인산화 정도가 적으므로 근장그물 $Ca^{2+}-ATPase$ 억제가 나타남을 제시해 주며, 근장그물 단백의 산화성 손상도 당뇨성 심근질한을 일으킬 수 있는 또 다른 요인 중의 하나로 생각된다.

The impairement of glucose metabolism is frequently associated in hyperthyroidism. The present study was performed to determine the effect of the thyroid hormone excess on insulin sensitivity and on insulin secretory function in vivo. Ten newly diagnosed hyperthyroid patients and fifteen healthy control subjects were subjected to frequently sampled intravenous glucose tolerance tests(FSIGT) after an overnight fast. Insulin sensitivity, represented by the insulin sensitivity index(S_1), was assessed by minimal model analysis of FSIGT data. Insulin secretion was measured by the total area under the insulin curve after glucose load. The results were as follows. 1) The K_G values, which represent glucose tolerance, were not different between the hyperthyroid patients and the normals(2.2+-0.3 vs. 2.5+-0.3%/min, p$gt;0.05). 2) S_1 was significantly decreased in the hyperthyroid patients in comparison to the normals(7.5+-1.4 vs. 2.6+-0.3X10^-4 min^-1/uU/ml, p$lt;0.05). 3) The basal insulin concentration was higher in the hyperthyroid patients than in the normals(8.3+-2.4 vs. 4.6+-0.4 uU/ml, p=0.07). In addition, the insulin secretory response to a glucose load was increased in the hyperthyroid patients as evidenced by the peak plasma insulin level(168.2+-30.4 vs. 89.2+-13.9 uU/ml, p$lt;0.05) and by the total area under the insulin curve(2641.1+-443.2 vs. 1696.7+-204.3 min uU/ml, p$lt;0.05). These results clearly demonstrated that insulin sensitivity was impaired in these newly diagnosed hyperthyroid patients. However, glucose tolerance was maintained by the increased insulin secretion (J Kor Soc Endocrinol 9:108-114, 1994).
