The data were analyzed using the Pearson correlation, independent t-test, and paired t-test. Results : Trunk control was significantly positively correlated with pulmonary function and respiratory muscle strength. Both groups showed a significant increase in trunk control and respiratory function. Conclusion : This study demonstrated that a conventional stroke rehabilitation program and trunk stability training have positive effects on respiratory function and respiratory muscle activation in stroke patients.

부모이혼에 대한 아동의 지각과 이혼가정자녀의 심리·행동적응문제와의 관계

주소희 한국가족사회복지학회 2003 한국가족복지학 Vol.- No.12

본 연구에서는 이혼가정자녀들이 부모가 이혼하는 과정에서 경험하게 되는 부모이혼에 대한 생각이 부모이혼 후 아동의 심리행동적응에 어떠한 영향을 미치는지 밝혀보고자 한다. 부모가 이혼한 가정의 아동 260명을 대상으로 부모이혼당시 아동의 연령에 따라 부모이혼에 대한 생각에 차이가 있는지 살펴보고 부모이혼에 대한 생각이 부모이혼 후 아동의 심리행동 적응에 영향을 주는지 살펴보았다. 즉 이혼당시 아동의 연령이 이혼에 영향을 준다면 그것은 이혼을 받아들이는 아동의 인지발달의 문제인지 혹은 연령과 상관없이 부모이혼에 대한 아동의 부정적인지가 부모이혼 후 심리행동적응을 더 잘 설명하는 요인인지 밝혀보고자 한다. 또한 부모가 이혼에 대해서 미리 아동에게 설명해 준 경우와 그렇지 않은 경우에 부모 이혼 후 아동의 심리행동적응에 영향을 주는지 살펴보았다. 연구결과, 학령기에 있는 아동이 학령전기나 유아기에 부모가 이혼한 아동보다 유기불안과 자기비난과 같은 부정적인 생각이 더 높게 나타났다. 이러한 부모이혼에 대한 아동의 생각은 부모이혼 후 아동의 심리행동적응문제에 영향을 주는 요인으로 나타났다. 한편 부모로부터 부모이혼에 대해서 설명을 들은 아동의 경우 부모이혼 후 심리행동적응문제가 더 낮은 것으로 나타나, 부모가 이혼하기 전에 아동에게 부모이혼을 미리 준비시켜주는 것이 아동의 심리행동적응에 정적인 영향을 준다는 사실이 입증되었다. 아동의 이혼당시연령과 부모이혼에 대한 생각 그리고 이혼에 대한 설명여부를 각각 통제한 후에 부모이혼 후 아동의 심리행동적응에 가장 큰 영향을 주는 요인을 조사한 결과 부모이혼에 대한 생각이 아동의 심리행동적응에 가장 큰 영향을 주는 요인으로 나타났다. 따라서 부모이혼으로 아동들이 경험하는 다양한 부정적인 생각들을 다루어 줄 필요성과 함께 아동이 부모이혼 후 발생하게 될 다양한 변화를 준비하도록 도움을 줄 필요성을 시사하였다. This study is concerned about how the children's beliefs on their parental divorce process might influence their adjustment in their parents' post-divorce stage. 260 children of divorced family are selected to analyze whether the children's beliefs of their parental divorce is related to children's age when their parents are divorced. Based of this information, the fact that children's beliefs on their parental divorce influence their adjustment problem on their new circumstances is also analyzed. More precisely, this study analyzed the followings. If children's age when their parents are divorced has impact on their parental divorce, it should be considered whether this influence is caused by children's cognitive developmental stage or by more robust factors such as children's negative thought on their parental divorce. Also, this study analyzes that children's adjustment on new circumstances caused by their parental divorce is influenced by the pre-advice that their parents are supposed to divorce. As a result of this study, it is found that school-age children have more negative thought on their parental divorce compared to those of preschool children or toddlers. The negative thought is manifested by children's abandonment-anxiety from their parents or self-hatred. As such, this study proves that the children's beliefs on parental divorce is influencing their adjustment problem on new circumstances. In the meantime, it is found that the children who were pre-noticed by the information of their parental divorce were more adaptive on new circumstances. It means that it is necessary to inform in advance their children on parental divorce for them to get some times to meet the scheduled parent's divorce. It is also found that the most important factor after considering the above-mentioned factors such as children's age, children's beliefs on parental divorce, and pre-notice about scheduled parent's divorce, is children's beliefs on parental divorce. Therefore, this study has implication on the necessity to deal with children's negative thought when they face parental divorce and the necessity to help children to meet with change that their parental divorce might cause.

Background: Cerebrovascular disease has a high death rate and serious aftereffects, and after one year, over 50% of stroke patients die or live in dependency. Recently in Korea, many studies about risk factors of cerebrovacular disease are reported, but according to changes of dietary (food) style, society and economy, there are some epidemiologic changes. This study was performed to correlate incidence of cerebrovascular disease with hypertension and diabetes mellitus, and also to investigate the incidence rate of ischemic stroke and hemorrhagic stroke and incidence time, season. Methods: During January 1,2001 to December 31,2001, 375 patients were diagnosed to cerebrovascular disease by CT and MRI. 304 patients were selected to have further studies performed who had a sufficient registry (chart, records). We investigated a retrospective study on ischemic stroke and hemorrhagic stroke respectively, about the age of incidence, sex, territory, season and the correlation between stroke and hypertension, diabetes mellitus. Results: Of the 304 patients, 102 patients were of ischemic stroke, and the average age of males were 62.7 years old, and that of females were 61.7 years old. Male to female ratio was 1: 1.125. Male patients were 47.1% (48 patients). and female patients were 52.9% (54 patients). In the distribution of the disease site, the middle cerebral arterial territory was the highest, with 50% (61 patients), and the risk factors of stroke were hypertension, 60.7% (67 patients) and diabetes mellitus, 24.5% (25 patients), respectively. 202 patients were of hemorrhagic stroke, and the average age of males were 52.4 years old and females were 68.1 years old. Male to female ratio was 1.126:1 (Male patients were 52.9% (107 patients), and female patients were 48.1%(95 patients). The distribution of disease site, subarachnoid hemorrhage were the highest, with 32.6% (66 patients), and the risk factors of stroke were hypertension, 57. 9% (117 patients), diabetes mellitus, 12.5% (25 patients), respectively. Conclusion: In the current status of cerebrovascular disease in Korea. it is reported that the incidence of hemorrhagic stroke has decreased, but in our study, hemorrhagic stroke has doubled, from what it had done before. Because it is considered that hospitals which can treat cerebral hemorrhagic patients are of a small number, relatively in Gwangju and the Chonnam area comparing to other areas. The age of incidence were early sixties, but it showed that the trends of getting older were greater, than those reported up until now in Korea.

This study used P.acnes, which causes acnes, and P.aerugmosa, Pseudomonase aeruginosa, as the antigen, and then blue egg-laying chickens, arakana mixed, to be immune to this antigen. After that, we measured the productivity of special antibody (IgY), characteristics of special antibody, antigenicity & molecular weight and antibiosis. The results were are Followed. We had three times of immune injection of each antigen (P.acnes, P.aeruginosa, P.acnes+P.aeruginosa). The second injection was after 2 weeks of the first shots, and the second injection was after 5 weeks of the second shots. The special antibody (IgY) was produced after I week of vaccine shot in lymph and after 2 weeks in yolk. The value steadily increased and reached its highest degree in 4 weeks. Especially, the mixed injection of two antigens showed much higher increase in antibodies than single antigen injection group. The fraction of special antibody that passed the DEAE-Sephacel column showed that the antibodies of P.acnes was located in 210∼325㎖, P.aeruginosa was in 230∼370㎖ and P.acnes+P.aeruginosa was located in 240∼360㎖. We measured the refine lgY with SDS-PAGE, and we observed similarities in three antibodies. They showed heavy chain in 66kDa and light chain m 29kDa. We analyzed the antigenicity for individual germ by western blotting. P.acnes showed one near 40kDa band. P.aeruginosa showed 2 near 55kDa, 2 in 45kDa, 1 in 36kD, 1 in 29kDa and 1 in 20kDa. As for P.acnes+P.aeruginos, it showed 1 in 45kDa, 1 in 38kDa, 29kDa and 2 antigenicity in 20kDa band. We measured the heat stability in each special antibody.

권현주,남수완,김광현,곽영규,김병우 동의대학교 기초과학연구소 1997 基礎科學硏究論文集 Vol.7 No.1

A bacterium producing Cyclodextrin Glucanotransferase (CGTase) and Cyclodextrinase (CDase) was isolated from soil, and named as Bacillus stearothermophilus KJ16 . The growth of the isolated strain occurred in two steps, and syntheses of CGTase and CDase were dependent on the growth cycle of the cell. CGTase was constitutively synthesized during the 1st growing phase. while CDase was synthesized inducibly during the 2nd growing phase. When the medium pH was controlled at 7.0, the maximun enzyme activities of CGTase and CDase were increased by 12-fold (1300 mU/ml) and 2-fold (225 mU/ml), respectively, compared with the pH-uncontrolled batch culture. The CGTase of the isolate converted soluble starch to CDs with the ratio of α-CD:β-CD:γ-CD=42:46:12 at 55℃. The optimal pH and temperature of CGTase were 6.0 and 60℃,respectively and the optimal pH and temperature of CDase were 6.0 and 55℃. The molecular weights of the purified CGTase and CDase were estimated to be 65,000 and 68,000 dalton, respectively, Among serveral substrates, γ-CD was most rapidly hydrolyzed by the purified CDase.
