This study was designed to exam the aged's needs for spiritual nursing care. The purpose was to serve as a basis for the development of spiritual nursing practice. The major findings are as follows : 1. The degree of needs for spiritual nursing care as area was that needs of love and relationship mean 22.0, needs of meaning and object mean 28.2, needs of forgiving mean 13.5. Total needs for spiritual nursing care mean 63.7, which was on the upper middle level. The needs of meaning and object was rated highest. 2. Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

In this study, we prepared ACFs with a high specific surface area from various precursors (rayon, pitch, and oxidized polyacrylonitrile-based fibers) by a steam-activation technique and investigated the effects of the micropore and mesopore fraction on 2-CEES adsorption behaviors. The activation time was precisely controlled so that the activation yield was in the range of 35–40% to ensure the mechanical properties of the ACFs. The N2 adsorption isotherm characteristics at 77K were confirmed by Brunauer–Emmett–Teller, Barrett–Joyner–Halenda and non-local density functional theory equations. The adsorption capacities of the ACF were measured by breakthrough experiments in the gas phase (750 μg/mL of 2-CEES in N2 flow). The removal efficiency of the ACFs was evaluated and compared with that of AC. From the results, specific surface areas and total pore volume of the ACF were determined to be 1380–1670 m2/g and 0.61–0.82 cm3/g, respectively. It was also observed that various pore characteristics of ACF were found to be dependent on crystallite structure of each precursor. The break through time (C/C0 = 0.10) was in the order of Oxi-Pan-H-9-2 < Saratoga AC < Rayon-H-9-3 < Pitch-H-9-4. This indicates that 2-CEES adsorption capacity could be a function not only of specific surface area or total pore volume, but also of sub-mesopore volume fraction in the range of 1.5–2.5 nm of adsorbents.

As a result of extensive research efforts on the oriental medicinal herbs, some of their interesting biological activities have been elucidated. In the present study, antifatigue effects of two natural food supplements consisting of oriental herbs, Vital and Vigilor, were investigated using the ICR mice. The mice were fed with antibiotic-free normal mouse feed containing Vital or Vigilor for 14,28, or 31 days and then subjected to forced swim tests. In a test carried out in melting-ice water, Vital and Vigilor significantly increased the exhaustion times of the 28 day-fed mice by 26.9 % (p < 0.01) and 16.2% (p < 0.05), respectively. However, in the other test performed at 15±0.5℃ using 31 day-fed mice, Vigilor failed to increase the exhaustion time significantly (at p< 0.05), while Vital showed antifatigue effect by increasing the swimming time by 29.9% (p<0.01). Neither of Vital nor Vigilor exerted antifatigue effects in a swim test carried out on day 14 after the initiation of feeding. These results suggest that Vital and Vigilor exhert antifatigue effets when administered for a sufficient period of time by enhancing the health of the host animals.

김경혜(Kim, Kyung-Hye),최경수(Choi, Kyong-Soo) 한국경영교육학회 2020 경영교육연구 Vol.35 No.1

[연구목적] 본 연구의 목적은 사외이사의 실질적인 영향력이 기업의 투자효율성에 미치는 영향을 분석하는 것이다. [연구방법] 연구목적을 수행하기 위해, 2003년부터 2015년까지 유가증권시장과 코스닥 시장 상장기업들을 대상으로 실증분석을 실시하였다. [연구결과] 유가증권시장의 경우, 사외이사의 실질적 영향력은 투자효율성과 유의한 관계를 나타내지 않는 것으로 나타났다. 반면, 코스닥시장의 경우에는, 둘 간에 체계적인 양(+)의 관계가 있는 것을 발견하였다. [연구의 시사점] 사외이사의 역할에 대한 기존연구들은 대부분 형식적인 사외이사의 영향력에 초점을 맞추고 있으며, 경영자에 대한 사외이사의 실질적인 역할 및 영향력을 고려하고 있는 연구들은 미미한 실정이다. 이러한 상황에서, 본 연구는 사외이사의 실질적인 영향력을 나타내는 차별화된 지표를 중심으로 연구를 수행했다는 점에서 공헌점이 존재한다. 또한, 본 연구는 유가증권시장과 코스닥시장 별로 사외이사의 실질적인 영향력 또는 역할이 다를 수 있다는 점을 제공함으로써, 기업의 다양한 이해관계자 및 연구자들에게 실무적으로 의미 있는 시사점을 제공할 것으로 기대된다. [Purpose] In this paper, we investigate the effect of outside director’s material influence on investment efficiency. [Methodology] To perform the research objective, we choose to focus on KOSPI and KOSDAQ firms and collect data for fiscal years 2003-2015. [Findings] For KOSPI sample, we find no significant association between outside director’s effective power and investment efficiency. On the other hand, for KOSDAQ sample, we find significant positive association between outside director’s effective power and investment efficiency. [Implications] Most of the prior researches focus on the nominal influence of outside director and there are few studies which considers the material influence of outside director. In this circumstance, this paper is different since we focus on the material influence of outside director. In addition, by demonstrating that the material influence of outside director might be different between markets, we provide a new insight about the practical role of outside director.

박성언,박수진,엄용빈,김종배,송혜원,박상욱,김양수,김근희 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 1999 Journal of biomedical laboratory sciences Vol.5 No.1

일반적으로 임상검사실에서 vancomycin resistant enterococci(VRE)를 검출하는 일은 어렵고, 시간이 많이 들며, 검체처리 비용도 많이 든다. 따라서 본 실험은 임상검체에서 분리된 세균으로부터 VRE를 신속하게 확인하고, 진단하기 위한 방법으로서 다중 중합효소 연쇄반응을 확립하였다. 본 실험에 사용된 primer는 장구균에 특이한 유전자인 vanA, vanB, vanC-1, vanC-2/3각각의 염기서열을 기초로 primer를 제작하고, 다중 중합효소 연쇄반응을 실시하여 임상검체로부터 분리된 VRE 유전자의 type 및 분포율을 조사하고자 하였다. 국내에서 분리된 75주의 장구균을 대상으로 다중 중합효소 연쇄반응을 실시한 결과 36주의 분리균주에서 vancomycin에 대해 높은 저항성을 보이는 vanA 유전자를 가진 것으로 나타났다. 그리고 18주에서는 vancomycin에 낮은 저항성을 내성을 보이는 vanC-1또는 vanC-2/3유전자를 보유한 것으로 나타났다. 따라서 본 실험에서 확립한 다중 중합효소 연쇄반응 기법은 신속한 VRE 진단 방법으로 이용할 수 있을 것이다. It is generally difficult, time-consuming, and expensive for the clinical laboratory to detect vancomycin resistant enterococci (VRE). The aim of this study was to develop and evaluate the multiplex polymerase chain reaction (PCR) assay system as a diagnostic tool for the rapid detection of VRE from clinical samples and/or for the identification of VRE from the bacterial strains isolated from clinical specimens. Specific primers, designed from the nucleotide sequences respectively encoding the vanA, vanB, vanC-1, vanC-2/3 genes in enterococci, were coupled in a multiplex PCR assay system. With this multiplex PCR assay system, we investigated the incidence rates and types of VRE isolated from clinical samples. A total of 75 strains of enterococci were isolated in 3 general hospitals in Korea. Of these isolates, 36 strains showed a pattern of highlevel vancomycin resistance which associated with vanA gene, whereas 18 strains showed lowlevel vancomycin resistance associated with vanC-1 or vanC-2/3 gene. Thus, multiplex PCR assay method established in this study could be applied for the rapid detection of VRE.

Lee, Dahae,Lee, Dong-Soo,Jung, Kiwon,Hwang, Gwi Seo,Lee, Hye Lim,Yamabe, Noriko,Lee, Hae-Jeong,Eom, Dae-Woon,Kim, Ki Hyun,Kang, Ki Sung The Korean Society of Ginseng 2018 Journal of Ginseng Research Vol.42 No.1

Background: The aim of the present study was to evaluate the potential protective effects of six ginsenosides (Rb1, Rb2, Rc, Rd, Rg1, and Rg3) isolated from Panax ginseng against tacrolimus (FK506)-induced apoptosis in renal proximal tubular LLC-PK1 cells. Methods: LLC-PK1 cells were treated with FK506 and ginsenosides, and cell viability was measured. Protein expressions of mitogen-activated protein kinases, caspase-3, and kidney injury molecule-1 (KIM-1) were evaluated by Western blotting analyses. The number of apoptotic cells was measured using an image-based cytometric assay. Results: Reduction in cell viability by $60{\mu}M$ FK506 was ameliorated significantly by cotreatment with ginsenosides Rg1 and Rb1. The phosphorylation of p38, extracellular signal-regulated kinases, and KIM-1, and cleavage of caspase-3, increased markedly in LLC-PK1 cells treated with FK506 and significantly decreased after cotreatment with ginsenoside Rb1. The number of apoptotic cells decreased by 6.0% after cotreatment with ginsenoside Rb1 ($10{\mu}M$ and $50{\mu}M$). Conclusion: The antiapoptotic effects of ginsenoside Rb1 on FK506-induced apoptosis were mediated by the inhibition of mitogen-activated protein kinases and caspase activation.

혈액암환자에서 조혈모세포 이식 후 따르는 헤르페스 바이러스 감영 양상

이호섭,탁희상,신성훈,김양수,남성진,김혜수,박진희,정수현,김성빈,김예나 고신대학교 의과대학 2010 고신대학교 의과대학 학술지 Vol.25 No.1

배경 : 헤르페스바이러스과에는 단순포진 바이러스(HERPES SIMPLEX VIRUS, HSV), 수두대상포진 바이러스 (VARICELLA-ZOSTER VIRUS, VZV), 엡스타인-바 바이러스 (EPSTEIN-BARR VIRUS, EBV), 그리고 거대세포 바이러스 (CYTOMEGALOVIRUS, CMV) 등이 있다. 헤르페스바이러스 감염은 혈액암환자에서 조혈모세포 이식 환자에서 전파 (dissemination), 이차감염, 세균 중복 감염의 심각한 합병증을 일으킬 수 있다. 하지만 항암약물치료를 받는 림파종 환자에서 항 바이러스 약제의 사용 용량과 기간에 대한 concensus는 없다. 헤르페스바이러스 감염에 대한 발생율과 위험인자를 후향성으로 분석하였다. 방법 : 고신대학교 복음 병원에서 1995년 6월부터 2009 년 2월 사이에 새롭게 진단되어 조혈모세포 이식을 받은 전체 58명의 환자들이 후향적으로 현 연구에 등록했다. 헤르페스 바이러스 감염은 임상적 진단, 혈청학적 검사 또는 병리학적 진단에 기초하여 확진한다. 환자들의 특성은 다음과 같다: 평균 연령은 44세 (범위 19-62세)였고 남녀비는 30:28이었다. 등록된 질환은 백혈병 (n=9, 15.5%), 림프종 (n=30, 51.7%), 다발성 골수종 (n=12, 20.7%), 재생불량성 빈혈 (n=6, 10.3%) 그리고 골수이형성증후군 (n=1, 1.7%)이 포함되었다. 결과는 chi-squre test나 independent samples T test를 사용하여 분석되었다. Multivariate analysises에 대해 logistic regression test를 사용하였다. 결과 : 15명의 환자들 (25.9%)에서 조혈모세포 이식후 헤르페스 바이러스 감염이 발생하였다. 조혈모세포 이식 5년간 누적 발생율은 53.9%였다. Univariate analyses에서 헤르페스 바이러스 감염에 대한 유의한 위험 인자는 없었다. 하지만 조혈모세포 이식후 생존 기간(40.18 ± 30.14 months vs 20.06 ± 26.67 months, p=0.018)은 헤르페스 바이러스 감염의 낮은 발병율과 유의한 관련성이 있었다. 이식 편대 숙주질환 (GVHD)의 존재 (37.5% in developed GVHD vs 0% in no GVHD, p=0.200), 동종조혈 모세포 이식에서 면역억제요법의 기간 (15.98 ± 14.02 months vs 6.78 ± 3.67 months, p = 0.374)은 헤르페스 바이러스 감염에 대한 위험인자가 아니었다. 결론 : 조혈모세포 이식 후 생존 기간은 어사이클로비어 예방을 받은 혈액암 환자에서 헤르페스 바이러스 감염의 낮은 발병율과 연관성이 있는 것으로 보인다. 저용량의 어사이클로비어 예방은 헤르페스 바이러스 감염의 고위험군인 조혈모세포 이식을 받은 혈액암 환자에 필요하리라 생각된다. Background : Herpesviridae family includes herpes simplex virus, varicella zoster virus, Epstein-Barr virus, and cytomegalovirus, etc. Herpesviridae viral infection (HVI) can lead to serious complications including dissemination, secondary infection, bacterial superinfection in patients with hematologic malignancy following hematopoietic stem cell transplantation (HSCT). But there was no consensus on the dose and duration of antiviral agents prophylaxis in patients undergoing chemotherapy. We retrospectively analyzed the incidence and the risk factors for HVI. Method : A total of 58 patients who newly diagnosed and received HSCT with prophylaxis of acyclovir at the Kosin University Gospel Hospital, Busan, Korea between June 1995 and February 2009 were enrolled retrospectively in the current study. HVI was confirmed based on clinical diagnosis, serologic test or pathologic diagnosis. The characteristics of the patients were as follows: the median age was 44 years (range 19-62 years) with a female-to-male ratio of 30:28. The enrolled diseases included leukemia (n=9, 15.5%), lymphoma (n=30, 51.7%), multiple myeloma (n=12, 20.7%), aplastic anemia (n=6, 10.3%) and myelodysplastic syndrome (n=1, 1.7%). The results were analyzed using a chi-square test and independent samples T test. For the multivariate analysis, we used logistic regression test. Results : Fifteen patients (25.9%) developed HVI after HSCT. The cumulative incidence of HVI was 53.8% at 5 years after HSCT. In univariate analysis, there was no significant risk factor for HVI. The presence of graft-versus-host disease (GVHD) (37.5% in developed GVHD vs. 0% in no GVHD, p=0.200), duration of immunosuppressive therapy (IST) in allo-SCT (15.98 ± 14.02 months vs. 6.78 ± 3.67 months, p = 0.374) were not risk factors for HVI. Conclusion : The incidence of HVI was similar to that in historical other studies. There was no risk factor associated with development of HVI. Most of the HVI occurred within the first 24 months after transplantation. So long term use of antiviral prophylaxis may be needed to prevention of HVI after HSCT.
