The purpose of this study is to understand the mediating effect of self-leadership in the process of understanding the effects of nursing job performance and job satisfaction in the nursing work environment perceived by nurses. In this study, nurses who worked for more than one year at three general hospitals located in Province A. Total of 225 data were used for the final analysis. Date analyzed using the SPSS 22.0 program by t-test, ANOVA, Pearson's correlation coefficient and hierarchical regression analysis. Self-leadership was found to play a partial mediating role in the relationship between nursing work environment and nursing job performance(z=4.30, p<.001) and between nursing work environment and job satisfaction(z=3.70, p<.001). Therefore, in order to improve nursing job performance and job satisfaction, it will be necessary to establish a management plan that can improve the nursing work environment and improve self-leadership. 연구의 목적은 간호사가 지각하는 간호업무환경에서 간호업무성과와 직무만족이 미치는 영향을 이해하는 과정에서 셀프리더십의 매개효과를 파악하기 위함이다. 본 연구에서는 A도에 소재한 종합병원 3곳에서 1년 이상 근무한 간호사를 대상으로 하였고, 총 225개의 자료를 최종분석에 사용하였다. 자료분석은 SPSS 22.0 프로그램을 사용하여 t-검정, ANOVA, Pearson의 상관계수 및 위계적 회귀 분석을 사용하였다. 간호업무환경과 간호업무성과의 관계에서 셀프리더십은 부분 매개역할(z=4.30, p<.001)을 하고 있으며, 간호업무환경과 직무만족의 관계에서 셀프리더십은 부분 매개역할(z=3.70, p<.001)을 하는 것으로 나타났다. 따라서 간호업무성과와 직무만족을 증진시키기 위해 간호근무환경의 개선과 셀프리더십을 향상시킬수 있는 관리방안의 수립이 필요할 것이다.

데이터베이스 공유 시스템(Database Sharing System : DSS)은 고성능 트랜잭션 처리를 위해 제안된 시스템이다. DSS에서 고속의 통신망으로 연결된 노드들은 별도의 메모리와 운영체제, 그리고 DBMS를 가지며, 데이터베이스를 저장하고 있는 디스크는 모든 노드에 의해 공유된다. 빈번한 디스크 액세스를 피하기 위해 각 노드는 자신의 메모리 버퍼에 최근에 액세스한 페이지들을 캐싱한다. 그러나 동일한 페이지가 여러 노드에 의해 동시에 캐싱될 수 있으므로, 각 노드가 최신의 내용을 항상 엑세스하기 위해서는 캐싱된 데이터의 일관성이 유지되어야 한다. 본 논문에서는 로킹 오버헤드를 줄이기 위해 주사본 권한을 이용하여 데이터베이스를 논리적으로 분할한 DSS 구조에서 필요한 캐쉬 일관성 기법들을 제안한다. 제안된 기법들은 캐쉬 일관성을 위해 소요되는 메시지 전송량과 디스크 입출력 오버헤드를 줄임으로써 성능을 향상시키며, 데이터베이스 부하가 동적으로 변하는 경우에도 효율적으로 동작한다는 장점을 갖는다. Database sharing system (DSS) refers to a system for high performance transaction processing. In DSS, the processing nodes are locally coupled via a high speed network and share a common database at the disk level. Each node has a local memory, a separate copy of operating system, and a DB'\fS. To reduce the number of disk accesses, the node caches database pages in its local memory buffer. However, since multiple nodes may be simultaneously cached a page, cache consistency must be cnsured so that every node can always access the'latest version of pages. In this paper, we propose efficient cache consistency schemes in DSS, where the database is logically partitioned using primary copy authority to reduce locking overhead, The proposed schemes can improve performance by reducing the disk access overhead and the message overhead due to maintaining cache consistency, Furthermore, they can show good performance when database workloads are varied dynamically.

김신희(Shin-Hee Kim),황석연(Seock-Yeon Hwang),박오성(Oh-Sung Park),김무강(Moo-Kang Kim),정영진(Young-Jin Chung) 한국식품영양과학회 2005 한국식품영양과학회지 Vol.34 No.7

한국에서 자생하는 흑송의 솔잎을 재료로 하여 항당뇨효능에 대한 생리활성을 규명하고자 STZ로 당뇨를 유발시킨 흰쥐에 솔잎증류액을 15일간 복강투여 후 체중, 혈당, OGTT, 혈액성분에 미치는 영향 및 간과 췌장의 조직병리학적 변화를 관찰하였다. 솔잎 투여군의 체중은 솔잎투여 6일째에 잠시 체중의 상승이 나타났을 뿐 그 이후에는 DM군에서와 같이 체중의 증가를 보이지 않았다. 공복혈당은 DM군에 비해 솔잎투여군에서 용량효과적으로 낮아지는 경향을 보였으며 15일째에 HP군에서 NC군의 수준으로 근접하였다. 구강내당능 검사결과 혈당곡선은 DM군에 비해 통계적 유의성은 없었으나 솔잎투여군에서 투여용량에 따라 감소경향을 보였다. 간기능관련지수로서 혈장내 total protein, albumin, AST는 솔잎투여에 따른 변화가 없었고, ALP와 ALT는 솔잎투여군 모두에서 DM군에 비해 감소하는 경향을 나타내었다. 신장기능 관련지수에서는 creatinine, uric acid, calcium, IP는 개선 경향이 관찰되지 않았으나, BUN에서는 DM과 비교시 솔잎투여군 모두에서 용량효과적으로 개선되는 경향을 보였다. 지질대사관련지수로서 total cholesterol, TG, HDL-C, LDL-C 농도는 모든 실험군간에 유의적인 차이를 보이지 않았다. 간조직과 췌장조직 병리학적 관찰결과 간조직의 경우 DM군과 솔잎투여군의 일부에서 염증세포의 침윤이 부분적으로 관찰되었고 췌도세포에서는 DM군은 췌장실질의 괴사, 출혈성 병변, 지방세포의 괴사가 관찰되었으나 솔잎투여군 모두에서 DM군에 비해 억제되는 현상을 관찰할 수 있었다. 결론적으로 솔잎추출물 투여에 의해 공복혈당이 낮아지고 당내성이 높아지는 경향을 보였고 간기능 지표 중 ALP와 ALT, 신장기능지표 중 BUN만이 솔잎 투여에 의한 개선효과를 나타내었으며, 혈중 지질 개선효과는 나타내지 않았다. To investigate the effect of Pinus densiflora on biochemical parameters in typeⅠdiabetic rats, we evaluated the changes of body weight, fasting blood glucose level, oral glucose tolerance test (OGTT) and biochemical parameters after the intraperitoneal injection of distilled solution of Pinus densiflora in streptozotocin (STZ)-induced rats. Thirty-seven male Sprague Dawley rats (180±10 g) were divided into four groups; diabetic mellitus (DM) group received STZ (50 ㎎/㎏ BW, i.v.); low level of pine extract (LP) group received Pinus densiflora (5 ㎎/㎏ BW, i.p.), high level of pine extract (HP) group received Pinus densiflora (10 ㎎/㎏ BW, i.p.) after the single injection of STZ (50 ㎎/㎏ BW, i.v.), respectively. Normal control (NC) group received saline. The change of fasting blood glucose level and OGTT were measured using glucocard Ⅱ, and the change of biochemical parameter were measured by Automatic Chemistry Analyzer (Hitach-747, Japan). Mean body weight change of DM group was retarded greatly by STZ-exposure. While, body weights of LP and HP groups were progressively increased with some fluctuation, although the increase rates were slower than that of NC group. Fasting blood glucose levels of LP and HP groups were reduced by Pinus densiflora injection, although the fasting blood glucose levels were higher than that of NC group. The results of OGTT was significantly improved in both of LP and HP group compared to DM group. Increases of blood glucose, alanine aminotransferase(ALT), alkaline phosphatase (ALP) and blood urea nitrogen (BUN) levels by STZ-exposure were attenuated by the Pinus densiflora treatment (p<0.05). From the results, it was suggested that Pinus densiflora has a tendency to decrease STZ-induced toxicity in terms of monitoring fasting blood glucose, OGTT and some biochemical parameters of rat.

김신희(Shin Hee Kim),박미연(Mi Yeon Park),이용언(Young Eon Lee),조묘헌(Myo Heon Cho),장동석(Dong Suck Chang) 한국수산과학회 1997 한국수산과학회지 Vol.30 No.4

Vibrio cholerae non-O1 FM-3 was isolated from sea water, and it showed the same bacteriological characteristics as Vibrio cholerae non-O1 ATCC 25872. V. cholerae non-O1 FM-3 presented the highest hemolytic activity at stationary phase of its growth. The hemolytic activity was decreased in accordance with increasing of protease activity of its cultural supernatant. The characteristics of the hemolysin produced by V. cholerae non-O1 FM-3 were investigated after partial purification with a Sephadex G-100 chromatography. The hemolytic activity of purified protein was stable at 4℃ while it was completely lost by heating at 60℃ for 30min. The activity of hemolysin was increased by addition of divalent canons such as Ca^(2+), Mg^(2+), and Mn^(2+) while it was inhibited by additions of Zn^(2+). When the hemolysin was incubated with suspensions of erythrocytes at 4℃ and 37℃, respectively, hemolysis was not observed at 4℃ but at 37℃, It means that hemolysis by purified hemolysin was temperature-dependent while its binding step of hemolysin to cell membrane was temperature-independent.

In this paper, the discussion is deployed under the assumption to achieve a unified nation of South Korea and the North Korean regime and the agreement for the unification of the system have been made, and in the context of running a full-fledged South Korea and North Korea of education integration. This paper want to expand the discussion of teacher policy centered on the re-appointment and the re-education of North Korea teachers for educational reform and integration in North Korea region after unification. After unification, re-appointment of North Korean teachers should be as much as possible by re-education for mind and educational integrationas inner integration of two Koreas and social integration. And to North Korea teachers who get a chance for re-appointment continually provides opportunities for academic training in service, which help to be a expertise of subject and democracy education.

Vibrio alginolyticus 가 Shewanella sp. SR - 14 의 미세조류 증식저해 활성에 미치는 영향

김신희(Shin Hee Kim),김지회(Ji Hoe Kim),박희연(Hee Yeon Park),이태식(Tae Seek Lee),박정흠(Jeong Heum Park),장동석(Dong Suck Chang) 한국수산과학회 2001 한국수산과학회지 Vol.34 No.5

미세조류 증식 저해균 Shewanella sp. SR-14와 연안해역에서 우점종으로 분포하는 세균인 Vibrio alginolyticus가 규조, Chaetoceros calcitrans의 증식에 미치는 영향 그리고 V. alginolyticus가 Shewanella sp. SR-14의 C. calcitrans 증식저해 활성에 미치는 영향을 혼합배양으로 측정하였다. Shewanella sp. SR-14와 해수에서 분리한 V. alginolyticus는 미세조류 배양용 무기배지에서 단독 또는 혼합 배양하여도 잘 증식 하였으며, C. calcitrans와 혼합배양시 Shewanella sp. SR-14는 조류증식을 저해한 반면 V. alginolyticus는 이 조류의 증식을 촉진 하였다. 조류가 첨가된 배지에 Shewanella sp. SR-14의 최초 접종균수가 V. alginolyticus와 거의 같거나 1 log 정도 적게 접종되었을 때에는 C. calcitrans에 대한 Shewanella sp. SR-14의 증식 저해활성이 유지되었으나 V. alginolyticus의 최초균수가 Shewanella sp. SR-14보다 3 log 이상 많았을 때에는 조류증식 저해활성이 나타나지 않았다. The algicidal activity of Shewanella (formerly Alteromonas) sp. SR-14 against diatom, Chaetoceros calcitrans was reported in our previous papers. In this study, the effect of Vibrio alginolyticus on the algicidal activity of Shewanella sp. SR-14 was examined under the optimum algicidal conditions, i.e., temperature (21 1℃), light intensity (4,000 lux), and light: dark cycle (12 hour:12 hour). Shewanella sp. SR-14 grew well in the presence or the absence of V. alginolyticus in Conwy medium. Algal growth was only inhibited by Shewanella sp. SR-14. V. alginolyticus did not show the algicidal activity. Growth of C. calcitrans increased synergistically with growth of V. alginolyticus. When the initial inoculum of V. alginolyticus was only l log cycle higher than that of Shewanella sp. SR -14, the effect of V. alginolyticus on the algicidal activity of Shewanella sp. SR-14 was insignificant during incubation of mixed culture, i.e., two bacterial species and the alga. However, when V. alginolyticus dominated Shewanella sp. SR-14 by 3 log cycles of bacterial counts, it was found that the strain SR-14 could not inhibited growth of C. calcitrans up to 5 days of incubation.

김신희(Shin-Hee Kim),강주섭(Ju-Seop Kang),이상준(Sang Jun Lee),정영진(Young-Jin Chung) 한국식품영양과학회 2008 한국식품영양과학회지 Vol.37 No.6

본 실험에서는 STZ로 당뇨를 유발시킨 흰쥐에 홍삼과 팽화홍삼의 항당뇨 효능에 대한 생리활성을 규명하고자 홍삼을 7주간 경구투여 후 체중, 혈당, 혈청 인슐린 및 아밀라아제, 지질관련 지수, OGTT, DNA의 산화적 손상정도 분석 및 췌장의 조직병리학적 변화를 관찰하였다. 체중증가는 실험 7주 후에 DM군과 비교 시 RG군에서 6.67배, PG군에서 5.25배 증가하였으나 DM군과 유의적인 차이는 없었다. 공복혈당은 DM군에 비해 RG군에서 11.54%, PG군에서 20.22%의 감소를 보였다. 구강내당능 검사결과 공복혈당, 포도당 투여 2시간 후 혈당은 DM군과 통계적 유의성은 없었다. 혈청 인슐린 농도는 PG군에서 가장 높게 나타났고, 혈청 아밀라아제 농도의 경우 RG군에서 높았으나 NC군보다는 낮게 나타났다. 혈청 총 콜레스테롤은 NC군을 제외한 모든 실험군 간에 유의적인 차이를 보이지 않았으나 혈청 중성지방의 경우 PG군에서 현저한 감소를 보였다(p<0.05). HDL-C는 NC군에 비해 당뇨유발군 모두에서 높게 나타났다. DNA 손상정도를 알아보기 위한 comet 분석에서는 PG군의 TL 및 TM은 NC군에서와 유사한 수준을 보였다. 췌장조직의 병리학적 관찰결과, 당뇨유발군 중 DM군의 췌장조직의 exocrine acinal cell 및 췌도세포에서는 focal 또는 multifocal cytoplasmic vacuolation과 췌장실질의 괴사 및 출혈성 병변이 관찰되었다. 이상의 결과로서 팽화홍삼의 투여가 홍삼에 비해 항당뇨 효과가 더 큰 경향을 보였으나 보다 확실한 결과를 위해 8주 이상의 홍삼 장기투여에 의한 항당뇨 효과 확인이 필요할 것으로 사료된다. Antidiabetic effect of Korean red ginseng (RG) processed by puffing in streptozotocin (STZ)-induced diabetic (DM) rats was investigated. Five week-old SD rats were divided into four groups; normal control (NC) group, DM group, red ginseng (RG) group and puffed red ginseng (PG) group. The RG and PG groups were orally provided with RG or PG dissolved in water (500 ㎎/㎏) respectively for seven weeks after single injection of STZ (50 ㎎/㎏, i.v.) followed by identification of DM. NC group received saline vehicle instead of STZ. At the end of feeding of RG or PG, the changes of fasting blood glucose, serum insulin and amylase level and serum lipid profiles were evaluated. Also, oral glucose tolerance test (OGTT), comet assay and histopathological examination were performed. At 7th week, the fasting blood glucose levels of the RG and PG groups were reduced compared to the DM group by 11.54% and 20.22%, respectively. The result of OGTT did not show significant differences among DM and two red ginseng groups. While serum insulin and TG levels were predominantly improved in PG group (p<0.05), serum amylase level was increased in RG group. Alkaline comet assay for checking the oxidative damage of DNA showed that TL (tail length, ㎛) and TM (tail moment) in the blood lymphocyte of PG group significantly decreased in contrast with DM group. Histopathological results of pancreas showed that destruction of exocrine as well as endocrine might be cured by the administration of RG and PG. These results suggest that PG could exert more protection against STZ-induced toxicity than RG group.

Objectives: The aim of this study was to examine whether there is an association between lifestyle and skincare behaviors and skin health status of adult women. Methods: A sample of 102 adult women aged 20s to 50s years old were conveniently recruited at several skin care center and cosmetics shops in Daegu, Korea. The subjects were examined for skin health status by Aramo-SG (AramHuvis Inc., Korea). The demographic and lifestyle characteristics and skincare behaviors surveyed by self-administered questionnaire. Univariate and multivariate analyses were performed to determine the factors related with skin health status using SPSS 18.0. Results: In univariate analysis, Aged over 30s (p<0.001), married (p<0.001) and appropriate drink (p=0.040) were positively associated with skin health status among demographic and lifestyle characteristics. Among the skincare behaviors, experience of homecare only significantly associated with skin health status (p=0.007). In multivatiate analysis, age and experience of homecare were independently significantly associated with skin health status after adjusting for other variables. Conclusions: An appropriate drink and experience of homecare were positively associated with management of skin health. Therefore, it is important to have proper skincare behaviors to keep sound skin condition.
