최문기(Choi, Moon-gi),손성진(Son, Sung-jin) 한국국제회계학회 2018 국제회계연구 Vol.0 No.80
본 연구는 PMS 특성(PMS 질적 특성, PMS 구성적정성, PMS 공정성)이 개인차원성과(조직태도 / 조직시민행동)와 조직차원성과(재무 / 비재무성과)에 미치는 영향을 살펴보고자 하였다. 이를 위해 PMS 문헌을 고찰하여 PMS 특성을 개념화 하였고, 개념화한 PMS 특성과 조직차원성과의 관계에서 개인차원성과는 매개역할을 하는지를 살펴보기 위해 경로분석을 수행하였다. 본 연구의 결과는 다음과 같다. 첫째, PMS 특성은 프로세스 및 학습과 성장성과, 고객성과의 개선에도 긍정적인 영향을 미쳤다. 둘째, PMS 특성은 조직태도, 조직시민행동의 개선에 긍정적인 영향을 미쳤다. 셋째, PMS 특성과 조직차원 비재무성과(프로세스 및 학습과 성장성과, 고객성과) 간의 관계에서 개인차원성과(조직태도, 조직시민행동)는 매개역할을 하였다. 다만, PMS 특성이 재무성과에 미치는 영향은 혼재되어 있었다. 본 연구는 다음과 같은 점을 시사하고 있다. 첫째, PMS는 경영관리 목적에 적합해야 한다. 둘째, PMS에서 사용하는 지표의 구성은 적정해야 한다. 셋째, PMS는 공정해야 한다. 그리고 이러한 PMS 특성이 확보된다면 조직태도와 조직시민행동을 경유하여 비재무성과가 개선될 수 있을 것이다. The purpose of this study is to examine the effects of PMS characteristics (PMS qualitative characteristics, compositional appropriateness of PMS, and PMS Justice) on performances of individual dimension (organizational attitude / organizational citizenship behavior) and performances of organizational dimension (financial / non-financial performances). To achieve the research objectives, We reviewed the PMS literature to conceptualize the PMS characteristics, and path analysis was conducted to examine whether individual dimension performances plays a role in the relationship between the conceptualized PMS characteristics and organizational dimension performances. The results of this study are as follows. Firstly, the PMS characteristics positively influenced performance of process & learning and growth, customer performance. Secondly, PMS characteristics positively influenced organizational attitude, organizational citizenship behavior. Thirdly, the performances of individual dimension (organizational attitude / organizational citizenship behavior) mediated the relationship PMS characteristics and nonfinancial performances of organizational dimension. However, the effects of the PMS characteristics on financial performance were mixed. This study suggests the following points. Firstly, PMS should be suitable for the business management purposes. Secondly, the composition of the indicators used in PMS characteristics should be appropriate. Thirdly, PMS should be fair. If such PMS characteristics are secured, non-financial performance can be expected to improve through the improvement of organizational attitude and organizational citizenship behavior.

Yongneup wetland protected area, the only high moor in Korea, is a core area to conserve biodiversity. Even though the Yongneup wetland protected area is relatively small, various plant species are distributed in the Yongneup wetland protected area because it includes various habitats showing different environmental gradients. Vascular plants distributed in the Yongneup wetland protected area were identified as a total of 376 taxa that is composed of 73 families, 217 genera, 322 species, 3 subspecies, 44 varieties and 7 forms. For endangered plants designated by the Ministry of Environment, 5 species including Trientalis europaea var. arctica, Lilium dauricum, Halenia corniculata, Lychnis wilfordii and Menyanthes trifoliata were found and 34 taxa were confirmed to be distributed only in the mountainous wetland habitats. Regarding naturalized plants, a total of 11 taxa were distributed, but most of them were distributed in the areas where artificial interference has occurred. And in areas inside the wetlands that are relatively well preserved, 2 species of Bidens frondosa and Erigeron annuus were observed. In this study, the occurrence and distribution of Pseudostellaria baekdusanensis M. Kim, which was recently found in Mt. Baekdu and reported as a new species, were identified in the Yongneup wetland protected area. A wetland is a very vulnerable area to drastic environmental changes and damages to its ecosystem could cause the extinction of rare plant species which are distributed only in the wetlands. Therefore, it is mandatory that current status of the Yongneup wetland protected area is evaluated and actions to prevent rapid environmental changes are taken. Fourteen separate investigations were conducted in 2013 and another four in 2014, to evaluate current status of the Yongneup wetland protected area. These investigations have provided us the basic information for future actions of conservation and restoration.

<P><I>Pseudomonas aeruginosa</I>, a Gram-negative bacterium of clinical significance, produces elastase as a predominant exoprotease. Here, we screened a library of chemical compounds currently used for human medication and identified diethylene triamine penta-acetic acid (DTPA, pentetic acid) as an agent that suppresses the production of elastase. Elastase activity found in the prototype <I>P. aeruginosa</I> strain PAO1 was significantly decreased when grown with a concentration as low as 20 μM DTPA. Supplementation with Zn<SUP>2+</SUP> or Mn<SUP>2+</SUP> ions restored the suppressive effect of DTPA, suggesting that the DTPA-mediated decrease in elastase activity is associated with ion-chelating activity. In DTPA-treated PAO1 cells, transcription of the elastase-encoding <I>lasB</I> gene and levels of the <I>Pseudomonas</I> quinolone signal (PQS), a molecule that mediates <I>P. aeruginosa</I> quorum sensing (QS), were significantly downregulated, reflecting the potential involvement of the PQS QS system in DTPA-mediated elastase suppression. Biofilm formation was also decreased by DTPA treatment. When A549 alveolar type II-like adenocarcinoma cells were infected with PAO1 cells in the presence of DTPA, A549 cell viability was substantially increased. Furthermore, the intranasal delivery of DTPA to PAO1-infected mice alleviated the pathogenic effects of PAO1 cells in the animals. Together, our results revealed a novel function for a known molecule that may help treat <I>P. aeruginosa</I> airway infection.</P>

<P><B>Objective</B></P><P>Electrocardiographic markers identifying malignant forms of early repolarisation (ER) from ER of normal variants are of prime clinical importance.

In particular, the characteristic morphology of ‘giant’ (wide, >80 ms) J-waves were observed during the perievent period in 5/12 patients with ERS.

<P>The composite cathode of an all-solid-state battery composed of various solid-state components requires a dense microstructure and a highly percolated solid-state interface different from that of a conventional liquid-electrolyte-based Li-ion battery. Indeed, the preparation of such a system is particularly challenging. In this study, quantitative analyses of composite cathodes by three-dimensional reconstruction analysis were performed beyond the existing qualitative analysis, and their microstructures and reaction interfaces were successfully analyzed. Interestingly, various quantitative values of structure properties (such as the volume ratio, connectivity, tortuosity, and pore formation) associated with material optimization and process development were predicted, and they were found to result in limited electrochemical charge/discharge performances. We also verified that the effective two-phase boundaries were significantly suppressed to ∼23% of the total volume because of component dispersion and packing issues.</P> [FIG OMISSION]</BR>

Moxibustion is one of the major healing techniques in Oriental medicine. It has been widely used in many diseases such as rheumatoid arthritis, Hashimoto disease, breech presentation, etc. However, till now, effects of moxibustion on natural killer (NK) cell activity and relations between sympathetic nerve system (SNS) and the immune alteration induced by moxibustion wert not well studied. This study was designed to evaluate effects of moxibustion on NK cell activity and the Intervention of SNS in the alteration of NK cell activity induced by moxibustion. Splenic NK cell cytotoxicity was measured in a standard 4-hour ^(51)Cr release assay. We measured the NK cell cytotoxicity after moxibustion stimulation for 1, 3, 5 and 7 days, and also measured the NK cell cytotoxicity after 3 and 7 days burn stimulation with similar temperature. Interleukin (IL)-2, -4 and interferon (INF)-γ in serum were measured by rat IL-2, -4 and INF-γ ELISA test kit. To evaluate the effects of sympathectomy on alteration of NK cell cytotoxicity, 6-hydroxydopamine (6-OHDA: 50 mg/kg) was used. We showed that NK cell activity of moxibustion stimulation group incrcased at the 3rd day, and declined at the 7th day in comparison with that of the control group. In thc moxibustion stimulation group, NK cell activity was significantly higher than the sham group at the 3rd day. On the contrary, in the burn stimulation group, NK cell activity was significantly higher than that of the sham groups at 3rd and 7th days. INF-γ level after 3 days in the moxibustion stimulation group was significantly higher than that of the sham group. IL-2 Ievel among groups were not different. IL-4 was not detected in serum with this method. Sympathectomy abolished the NK cell activity alteration induced by moxibustion. The results suggest that moxibustion modulates NK cell activity, along with INF-γ, and SNS is mediating these effects.
