장상민,김경일 중소기업융합학회 2018 융합정보논문지 Vol.8 No.4

본 연구는 국내 중소기업이 ICT도입을 통하여 글로벌화된 마케팅역량과 경영성과를 향상시키기 위한 실천적 방안 을 제공하고자 함에 그 목적이 있다. 독립변인으로 ICT도입을 종속변인으로는 마케팅역량과 기업성과를 설정하여 상관분석 을 실시한 결과 기술적인 요소로서 접근성, 추진가능성, 가시성이 ICT 도입에 중요한 영향을 미치는 것으로 나타났으며, 기술의 상대적 우위와 호환성은 ICT 도입에 영향을 덜 미치는 것으로 나타난 반면, 조직적 요소인 최고경영진의 지식 및 혁신성은 중소기업의 ICT 도입에 아주 중요한 영향을 미치는 것으로 나타났다. 경쟁적 압박 및 정부지원 같은 환경적인 요소는 ICT 도입에 상당히 기여한다. 데이터 분석 결과 ICT 도입은 중소기업의 마케팅 역량에 긍정적인 영향을 주는 것으 로 드러난다. 결과적으로 마케팅 역량은 기업의 경영성과에 상당히 중요하게 작용하고 잠재적으로 중소기업의 이익 창출에 크게 기여하는 것을 확인하였다. The purpose of this paper is to analyze the influence of marketing capabilities on business performance among SMEs. The results suggest that complexity, trialability, and observability are among the technological factors that have a significant influence on ICT adoption. Research advantage and compatibility do not influence ICT adoption. Meanwhile, organizational factors such as owner/manager knowledge and innovativeness significantly influence ICT adoption among SMEs. Environmental factors such as competitive pressure, institutional intervention contribute significantly to the adoption. Moreover, data analysis reveals that ICT adoption has a positive influence toward SMEs’ marketing capabilities. Finally marketing capabilities significantly influence a firm’s business performance.

p19ras Accelerates p73β-mediated Apoptosis through a Caspase-3 Dependent Pathway

장상민,김정웅,Kyung-Hee Choi 한국통합생물학회 2009 Animal cells and systems Vol.13 No.4

p19ras is an alternative splicing variant of the proto-oncogene c-H-ras pre-mRNA of p21ras. In contrast to p21ras, p19ras does not have a C-terminal CAAX motif that targets the plasma membrane and is localized to both the cytoplasm and nucleus. We found that p19ras activated the transcriptional activity of p73β through protein-protein interactions in the nucleus. p73 is known to play an important role in cellular damage responses such as apoptosis. Although p73 is a structural and functional homologue of p53, p73-mediated apoptosis has not yet been clearly elucidated. In this study, we demonstrate that the interaction between p19ras and p73β accelerated p73β-induced apoptosis through a caspase-3 dependent pathway. Treatment with DEVD-CHO, a caspase inhibitor, also strengthened p73β- mediated apoptosis through a caspase-3 dependent pathway. Furthermore, the enhanced transcriptional activity of endogenous p73β by treatment with Taxol was amplified by p19ras overexpression, which markedly increased caspase- 3 dependent apoptosis in the p53-null SAOS2 cancer cell line. Our findings indicate a functional linkage between p19ras and p73 in caspase-3 mediated apoptosis of cancer cells.

Purpose: The predisposition infection response organ failure (PIRO) score has been developed to be used in the emergency department (ED) to risk stratify sepsis case but has not been well studied domestically. The aim of this study was to compare the usefulness between the PIRO score and the mortality in emergency department sepsis (MEDS) score in predicting the mortality of septic patients admitted to the intensive care unit (ICU). Methods: We conducted a retrospective study of patients who were suspected to have sepsis and were admitted to the ICU via the ED during a period between January 2013 and June 2015. PIRO and MEDS scores were calculated from the ED data. A comparative analysis was performed the evaluate the areas under the receiver operator characteristic (ROC) curves for 28-day mortality. Results: During the 30-month period, a total of 199 patients diagnosed with sepsis were enrolled. Fifty-seven patients (28.6%) died within 28 days of presentation. The PIRO score showed increasing mortality with higher scores. The area under the ROC curve (AUC) for mortality was 0.890 (95% confidence interval [CI]=0.830 to 0.950) for PIRO and 0.705 (95% CI=0.609 to 0.801) for MEDS score. Conclusion: The MEDS score in the ED did not predict mortality better than PIRO score. The PIRO score was a good predictor of the outcome for patients with suspected sepsis. We believe that the PIRO score may be the most useful and appropriate clinical prediction tool for patients with suspected sepsis in the ED.

This study analyzed the applications of near real-time drought monitoring using satellite rainfall for the Korean Peninsula and un-gaged basins. We used AWS data of Yongdam-Dam, Hoengseong-Dam in Korea area, the meteorological station of Nakhon Rachasima, Pak chong for test-bed to evaluate the validation and the opportunity for un-gaged basins. In addition, we calculated EDI (Effective doought index) using the stations and co-located PERSIANN-CDR, TRMM (Tropical Rainfall Measurement Mission) TMPA (The TRMM Multisatellite Precipitation Analysis), GPM IMERG (the integrated Multi-satellitE Retrievals for GPM) rainfall data and compared the EDI-based station data with satellite data for applications of drought monitoring. The results showed that the correlation coefficient and the determination coefficient were 0.830 and 0.914 in Yongdam-dam, and 0.689 and 0.835 in Hoengseng-Dam respectively. Also, the correlation coefficient were 0.830, 0.914 from TRMM TMPA datasets and compasion with 0.660, 0.660 based on PERSIANN-CDR and TRMM data in nakhon and pakchong station. Our results were confirmed possibility of near real-time drought monitoring using EDI with daily satellite rainfall for un-gaged basins.

SPI를 활용한 GPM IMERG 자료의 적용성 평가

In this study, the GPM (Global Precipitation Mission) IMERG (Integrated Multi-satellitE retrievals for GPM) rainfall data was verified and evaluated using ground AWS (Automated Weather Station) and radar in order to investigate the availability of GPM IMERG rainfall data. The SPI (Standardized Precipitation Index) was calculated based on the GPM IMERG data and also compared with the results obtained from the ground observation data for the Hoengseong Dam and Yongdam Dam areas. For the radar data, 1.5 km CAPPI rainfall data with a resolution of 10 km and 30 minutes was generated by applying the Z-R relationship ($Z=200R^{1.6}$) and used for accuracy verification. In order to calculate the SPI, PERSIANN_CDR and TRMM 3B42 were used for the period prior to the GPM IMERG data availability range. As a result of latency verification, it was confirmed that the performance is relatively higher than that of the early run mode in the late run mode. The GPM IMERG rainfall data has a high accuracy for 20 mm/h or more rainfall as a result of the comparison with the ground rainfall data. The analysis of the time scale of the SPI based on GPM IMERG and changes in normal annual precipitation adequately showed the effect of short term rainfall cases on local drought relief. In addition, the correlation coefficient and the determination coefficient were 0.83, 0.914, 0.689 and 0.835, respectively, between the SPI based GPM IMERG and the ground observation data. Therefore, it can be used as a predictive factor through the time series prediction model. We confirmed the hydrological utilization and the possibility of real time drought monitoring using SPI based on GPM IMERG rainfall, even though results presented in this study were limited to some rainfall cases.

To elucidate the mechanism associated with the development of heavy precipitation system, a field experiment was carried out in Jejudo (or Jeju Island) and Marado, Korea from 22 June to 12 July 2006. The synoptic atmospheric conditions were analyzed using the National Centers for Environmental Prediction-National Center for Atmospheric Research’s (NCEP/NCAR) reanalyzed data, weather maps, and sounding data. The kinematic characteristics of each precipitation system were investigated by dual Doppler radar analysis. During the field experiment, data of four precipitation events with more than 20 mm rainfall were collected. In F case (frontal precipitation), a typical Changma front was dominant and the observation field was fully saturated. However there was no convective instability near the surface. LF case (low pressure accompanied with Changma front) showed strong convective instability near the surface, while a strong convergence corresponded to the low pressure from China accompanied with Changma front. In FT case (Changma front indirectly influenced by typhoon), the presence of a convective instability indicated the transport of near surface, strong additional moisture from the typhoon ‘EWINIAR’. The convergence wind field was ground to be located at a low level. The convective instability was not significant in T case (precipitation of the typhoon ‘EWINIAR’), since the typhoon passed through Jejudo and the Changma front was disappeared toward the northeastern region of the Korean peninsula. The kinematic (convergence and divergence) characteristics of wind fields, convective instability, and additional moisture inflow played important roles in the formation and development of heavy precipitation.
