AI 솔루션 기업 관점의 AI 바우처 지원사업 개선방안 연구
조지연,송인국 한국인터넷방송통신학회 2022 한국인터넷방송통신학회 논문지 Vol.22 No.4
최근의 팬데믹 상황에서 인공지능의 중요성은 더욱 부각되고 있으며, 주요국은 AI 기술주도권 확보를 위하여노력 중이다. 한국 정부도 AI경쟁력 확보를 위한 사업을 추진하며 정부투자를 지속적으로 확대하고 있다. 산업 육성을위한 정부사업의 효율적인 운영이 중요함에도 불구하고 이와 관련한 연구는 미미한 실정이다. 이에 본 연구는 AI 분야의대표적인 정부 사업인 AI 바우처 지원사업의 개선방안을 분석하고 제안한다. 지원사업 참여기업을 대상으로 인터뷰를수행하였으며, 내용 분석을 통하여 사업 추진과정의 이슈를 파악하고, 개선방안을 사업 준비, 진행, 종료 및 사후관리의단계별로 제시하였다. 본 연구는 AI의 중요성이 증가하는 시점에 성공적인 AI산업 육성을 위한 정부 지원사업의 개선방안을 제시하는데 의의를 둔다.

Purpose: In this study, we attempted to ascertain the proton magnetic resonance spectroscopy (${1}^H$ MRS) peak characteristics of human gastric tissue layers and finally to use the metabolic peaks of MRS to distinguish between normal and abnormal gastric specimens. Materials and Methods: Ex-vivo ${1}^H$ MRS examinations of thirty-five gastric specimens were performed to distinguish abnormal gastric tissues invaded by carcinoma cells from normal stomach-wall tissues. High-resolution 400-MHz (9.4-T) ${1}^H$ nuclear magnetic resonance (NMR) spectra of two gastric layers, a proper muscle layer, and a composite mucosasubmucosa layer were compared with those of clinical 64- MHz (1.5-T) MR spectra. Three-dimensional spoiled gradient recalled (SPGR) images were used to determine the size and the position of a voxel for MRS data collection. Results: For normal gastric tissue layers, the metabolite peaks of 400-MHz ${1}^H$ MRS were primarily found to be as follows: lipids at 0.9 ppm and 1.3 ppm; alanine at 1.58 ppm; N-acetyl neuraminic acid (sialic acid) at 2.03 ppm; and glutathione at 2.25 ppm in common. The broad and featureless featureless spectral peaks of the 64-MHz MRS were bunched near 0.9, 1.3, and 2.0, and 2.2 ppm in human specimens without respect to layers. In a specimen (Borrmmann type III) with a tubular adenocarcinoma, the resonance peaks were measured at 1.26, 1.36 and 3.22 ppm. All the peak intensities of the spectrum of the normal gastric tissue were reduced, but for gastric tumor tissue layers, the lactate peak split into 1.26 and 1.39 ppm, and the peak intensity of choline at 3.21 ppm was increased. Conclusion: We found that decreasing lipids, an increasing lactate peak that split into two peaks, 1.26 ppm and 1.36 ppm, and an increasing choline peak at 3.22 ppm were markers of tumor invasion into the gastric tissue layers. This study implies that MR spectroscopy can be a useful diagnostic tool for gastric cancer.
Spinal cord stimulation with sympathetically independent pain and sympathetically maintained pain
조지연,이승재,김양현 대한마취통증의학회 2013 Anesthesia and pain medicine Vol.8 No.2
Background: Complex regional pain syndrome (CRPS) is categorized into sympathetically maintained pain (SMP) and sympathetically independent pain (SIP). Spinal cord stimulation (SCS) is a promising approach in the treatment of severely disabling CRPS. Patients with good responses to sympathetic block before SCS are more likely to have positive responses to SCS than those with negative responses. This study compared the effects of SCS in patients with CRPS, of SMP and SIP categories. Methods: This was a retrospective study of 16 patients (SMP 8,SIP 8) with CRPS who had undergone trials of SCS. Eleven of the patients had permanent SCS device implants, and the pain relief levels at 1 and 6 months were recorded. Results: Sixteen patients with severe, incapacitating, and therapyresistant CRPS underwent SCS trials. Five patients (SMP 3, SIP 2) had poor pain relief during the trial despite adequate coverage. The remaining 11 patients (SMP 5, SIP 6) had permanent electrode implantation performed under local anesthesia and experienced good pain relief. The difference in VAS reduction was not significant between the two groups at the 1-month follow-up (P = 0.325) and the 6-month follow-up (P = 0.779). Conclusions: There were no statistically significant differences in VAS pain scores between the two groups. The favorable outcome in all 11 patients with only minor remaining symptoms or without remaining symptoms or severe recurrences suggests that SCS is an efficient treatment in SMP and SIP.
'고려대 한국어대사전'의 용언 활용형 표제어의 처리에 관하여
조지연,노석은,유희정,도원영 한국사전학회 2018 한국사전학 Vol.- No.32
In this paper, we aimed to reveal the reason and necessity of accepting the conjugated form of verbs as headword in the <Korea University Korean Dictionary> and introduce the result. The conjugated form of verbs has been regarded as a additional information of dictionary and has not given independent status as a headword. If the conjugated form of verbs are provided as independent information in the Korean dictionary, it is useful for people using dictionaries. In fact, even for a native speaker, it is difficult to know what the basic form of that conjugated verb is. In order to increase the convenience of dictionary users, we register 7,688 conjugated forms of verbs in the <Korea University Korean Dictionary>. The form selected as a headword is from verbs with high frequency or irregular changed form with difficulty of expecting. We introduced the processing method of microstructure of the dictionary such as pronunciation, part of speech, usage, related words.
