정예진,박남춘 한국전시산업융합연구원 2022 한국과학예술융합학회 Vol.40 No.3

Digital Transformation, which provides new business prospects and reinforces companies’ competitiveness by utilizing recent and developing digital technology, is becoming a vital strategy for firms. Throughout the COVID-19 crisis, the retail industry's Digital Transformation has also been speeding up. Retail businesses have begun introducing with Digital Transformation through a strategy called Omni-channel that incorporates the benefits of both offline and online channels. Omni-channel provides multiple services at once with overlapped offline and online services, and it also may be used diversely depending on the user's channel selections. Therefore, offering a consistent experience from consumers’ purchasing patterns is a very difficult task. Thus, more research is needed on how to give customers a consistent experience by actualizing and standardizing tangible and intangible services. To this purpose, a tool is required to rapidly and simply visualize various consumer experiences. This study proposes a service modeling tool that verifies feasibility of introductory services in advance and covers the complete processes of usage using new technology through the Omni-channel services. Particularly, considering the tool’s practical value, a toolkit was developed to focus on easing difficulty of usage and enhancing work efficiency. Primarily, through literature review on digital transformation and omnichannel, the need for pre-confirmation of technical suitability and service visualization was recognized during the service planning. Furthermore, case studies were used to select representative cases of domestic and international Omni-channel services. These representative cases were analyzed undertaken using service modeling. Subsequently, through shareholder workshops and by analyzing the suitability of tools, the necessity for a new tool for service planning was justified in an Omni-channel context. Lastly, a toolkit that includes a Pre-Serviceblueprint Map, Service Planning Board, and Keyword Cards was created to simulate diverse Omni-channel services. Moreover, it's utility in practice has been proven through case studies and heuristic evaluations. The toolkit developed in this work solves the main issues with standard service modeling and introduces specific tools for an Omni-channel shopping environment. This toolkit was developed based on the task processes of shareholders. These tools are expected to become a more effective simulation implement for discovering service concepts which are ideal for enterprises in the planning stages for building an Omni-channel environment. 최근 변화하는 디지털 기술을 활용하여 기업의 경쟁력을 강화하고 전사적 관점에서 새로운 비즈니스기회를 창출하는 디지털 트랜스포메이션(Digital Transformation)이 기업들의 필수 전략으로 자리 잡고 있다. 코로나19 위기 상황에서 유통업계의 디지털트랜스포메이션 또한 가속화되는 추세이다. 유통업계는 오프라인 매장과 온라인 채널의 장점을 결합한 옴니채널(Omni-channel) 전략을 통해 디지털 트랜스포메이션을 도입하고 있다. 옴니채널 쇼핑환경은 오프라인의 유형 서비스와 온라인의 무형 서비스를 중첩하여 동시에 다수의 서비스를 제공하며, 사용자의 채널선택에 따라 서비스 이용 방식이 다양해진다. 따라서, 옴니채널 환경에서 사용자들의 구매 패턴을 유형화하여 일관된 경험을 제공하는 것은 매우 어렵다. 때문에, 유무형의 서비스를 실제화시키고 표준화하여 고객에게 일관된 경험을 제공할 방법에 대한 연구가 필요하며, 이를 위해 다양한 고객 경험을 쉽고 빠르게 시각화할 수 있는 도구가 필요하다. 본 연구에서는 신기술을 활용한 옴니채널 서비스 기획 시 서비스의 도입 적합성을 사전에 확인하는 도구로써, 고객 이용 프로세스 전반에 걸친 서비스 모델링도구를 제안하였다. 특히, 실무에서의 도구 활용성을고려하여, 도구의 난이도 및 업무 효율성 개선에 중점을 두어 툴킷을 개발하였다. 우선, 디지털 트랜스포메이션과 옴니채널에 대한 문헌 고찰을 통해, 옴니채널서비스 기획 시의 기술 적합성 확인 및 서비스 시각화필요성을 확인하였다. 또한, 사례연구를 통해 국내외옴니채널 서비스 대표 사례를 선정하고, 서비스 모델링 기법을 적용하여 사례 분석을 진행하였다. 이후, 이해관계자 워크숍과 도구 적합성 분석을 통해, 옴니채널 환경에서의 서비스 기획을 위한 새로운 도구 필요성을 정의하였다. 최종적으로 Pre-Serviceblueprint Map, 서비스 기획 보드, 키워드 카드로 구성된 시뮬레이션 툴킷을 개발하였으며, 실무에서의 도구 활용도를확인하기 위해 사례연구와 휴리스틱 평가를 통해 툴킷의 유용성을 검증하였다. 본 연구에서 개발된 툴킷은 전통적인 서비스 모델링 기법의 핵심 문제를 해결하고 옴니채널 쇼핑환경에 특화된 도구를 제안하였으며, 실무 이해관계자들의업무 프로세스를 반영하여 실무 활용도가 있는 도구를 개발하였다. 이를 통해, 옴니채널 서비스를 기획하는 실무 환경에서 기업에 최적화된 서비스 컨셉을 발견하기 위한, 보다 효과적인 시뮬레이션 도구로써 활용될 수 있을 것이라 기대한다.

The purpose of this study is to analyze the effect of the additional design alternatives of apartment housing units at ground and top floors which is recently supplied by developers in Korea, and to find out which design alternatives influence the residents' preference to the floor level. For this research, popular floors and unpopular floors are chosen and the reasons are analyzed based upon the residents' survey. In this research, the most popular floors are upper floors(higher than 16th floor) and the most unpopular floor is Ground floor. Residents have preference for private garden at ground floor unit and rooftop terrace at top floor unit. Besides, preference to the living height is dominated by better environmental qualities of higher floors such as view, ventilation, and natural light.

시흥 폐광산 잔류광미로 인한 잠재적 환경오염 영향

정예진,이상훈 가톨릭대학교 자연과학연구소 2000 자연과학논문집 Vol.21 No.-

The Shi-heung mine has been closed since 1973. Although, some restoration work was done in 1995, there still remain some mine tailing around the mine and the adjacent rice field. Mine tailing samples were collected from the abandoned mine. Porewaters were extracted from the mine tailings. In addition to analysing the field samples, batch leaching tests were carried out in the laboratory to find any supporting evidence found in the field analysis. The pH of the tailing ranges from 6.24 to 7.23. Calcite in the studied area seems to influence on such pH range. Total concentration of Cu. Pb, Zn. Cd in the tailings is 3088ppm, 26213ppm, 11738ppm, respectively. The average concentrations of Cu. Cd, Pb, Zn in the porewater exceed the standard value of EPA for drinking water, implying a possible groundwater contamination. Although heavy metal concentrations in the groundwater were found to be below the EPA drinking water standard, spatial concentration variation of the metals in the groundwater indicates contamination from the source. In batch leaching test , heavy metals were leached rather constantly, with number of leachings. Batch leaching test conducted at pH 4 showed much higher leaching of the metals and this implies more heavy metals than the value of porewater can be leached as the rain pH decrease.

정예진,박지해,조진경,서경화,이동성,김윤철,강희철,송명종,백남인 대한약학회 2015 Archives of Pharmacal Research Vol.38 No.2

The stems of Zea mays L., otherwise known ascornstalks, were extracted with 80 % aqueous MeOH, andthe concentrated extract was successively partitioned withethyl acetate (EtOAc), normal butanol, and water. From theEtOAc fraction, a new lignan along with three knownflavonoids, tricin (1), salcolin A (2), and salcolin B (3),were isolated. The chemical structure of the lignan wasdetermined to be tetrahydro-4,6-bis(4-hydroxy-3-methoxyphenyl)-1H,3H-furo[3,4-c]furan-1-one (4) through spectroscopicdata analyses including NMR, MS, and IR. Allcompounds were isolated for the first time from this plant. The isolated compounds were evaluated for their inhibitoryactivity against NO production in LipopolysaccharideinducedRAW 264.7 cells and their protective activity inglutamate-induced cell death in HT22 cells. The compounds1, 2 and 4 showed anti-inflammatory effects withIC50 values of 2.63, 14.65, and 18.91 lM, respectively, aswell as neuroprotective effects with EC50 values of 25.14,47.44, and[80 lM, respectively.

페광산 복구지역 잔류장미로 인한 주변 지하수${\cdot}$토양 오염가능성-시흥광산 사례

정예진,이상훈 대한자원환경지질학회 2001 자원환경지질 Vol.34 No.5

시흥광산은 1973년 폐장되었으며 1990년 초에 선광장 및 광미야적장에 있던 광미들을 제거한 후 그 자리에 소각장을 건설하는 폐광 복원사업을 실시하였다. 그러나 현재에도 광미가 완전히 제거되지 않았으며 광산 가동기간동안 많은 양의 광미가 주변 토양 및 논으로 이동, 퇴적된 것이 확인되는 바 광미와 물 반응으로 인한 침출수 형성과 주변 지하수 토양의 중금속 오염이 예상된다. 된 연구는 잔류광미와 물 반응에 따른 광산배수의 지구화학적 진화과정을 분석하고 주변 지하수 · 토양 오염 가능성을 평가하고자 하였다. 광미에서 추출한 공극수는 깊이에 따라 그 농도가 증가함을 보여 광미-불 반응을 통하여 지속적으로 중금속이 용출됨을 시사한다. 광미 중금속 용출은 공극수뿐 아니라 표면과 심부에서 각자 채취한 광미시료들간의 화학성분 차이에서도 확인된다. 광산 배수 기원지역과 하부 지역의 지하수 시료를 거리에 따라 채취, 분석한 결과 Cd, Pb 및 Zn 등은 국내 및 미국환경청 음용수 기준을 초과하며 광산배수의 영향을 받은 결과로 해석된다. 실내 회분식 시험 결과 원소들은 농도가 급격히 감소하는 것과 비교적 일정한 농도를 보이는 두 가지 양상을 보였으며 이는 일부 원소들이 평형농도에 도달하고 있기 때문으로 생각된다 회분식 시험에 사용한 증류수의 평균 pH는 6.5∼7.0의 범위로 이를 pH 4로 조정한 결과 원소들의 용출량이 급격히 증가하였다. 본 지역의 잔류광미는 지속적으로 주변의 지하수와 토양을 오염시킬 것으로 판단되며 이는 산성비등의 영향으로 인하여 급격히 증가할 것이다. The Shihung mine was restored in the early 90's after abandonment for 20 yews since 1973. Although disposed mine tailings were removed and the site was replaced by an incineration plant, still some residual mine tailings remain in the places including the old mine tailing ditposal area and the adjacent agricultural area. These residual mine tailings are prone to impose an adverse impact on the soil and groundwater and needs investigation for the potential contamination. Mine tailing samples were collected from the old tailing disposal area and the iii paddy. The porewater from the mine tailing were extracted and analysed to investigate chemical changes along the reaction path. Batch leaching tests were also carried out in the laboratory to find any supporting evidence found in the field analysis. Evidence of elemental leaching was confirmed both by the mine tailing and the porewater chemistry in them. The element concentrations of Cu, Cd, Pb, Zn in the porewater exceed the standard for drinking water of Korean government and US EPA. Leaching of heavy metals from the mine tailing seem to be responsible for the contamination. In batch leaching test. heavy metals were either continuous1y released or declined rapidly. Combining the information with porewater variation with depths and the geochemical meodeling results, most of elements are controlled by dissolution and/or precipitation processes, with some solubility controlling solid phases (Cu, Pb, Fe and Zn). Batch leaching test conducted at fixed pH 4 showed much higher releases for the heavy metals up to 400 times (Zn) and this area is becoming more vulnerable to soil and groundwater pollution as precipitation pH shifts to acidic condition.

드라마 대사의 어휘 계량을 통한 교사-학생 관계의 변화 연구: 1990년-2010년대 청소년 드라마 대사의 문체를 중심으로

정예진,고혜원 현대문법학회 2024 현대문법연구 Vol.121 No.-

. This paper aims to explore the alteration of teacher-student relationships in youth dramas aired from 1991 to 2012, through the transcription of dialogues and quantitative lexical analysis. Selecting one drama per decade from the 1990s to the 2010s, the study employs morphological analysis and the weighted log- odds ratio to extract key words, categorized into nouns, verbs, adjectives, and sentence-closing ending. By ranking the extracted keywords by their centrality and selecting those of significance, the study examines how the dynamics between teachers and students have changed, discussing these changes in the context of actual drama dialogues. This paper is significant for its quantitative approach to drama dialogues, previously limited to socio-cultural interpretations based on a limited selection of works, offering a diachronic perspective on the shifting dynamics of teacher-student relationships. Dramas, reflecting the thoughts of their times, serve as a suitable medium for studying generational shifts, yet the extensive volume of material has hindered comprehensive research. This study anticipates future holistic approaches to drama analysis, enabling meaningful exploration of cultural and educational shifts over time.

Antilisterial Bacteriocin from Lactobacillus rhamnosus CJNU 0519 Presenting a Narrow Antimicrobial Spectrum

정예진,문기성 한국축산식품학회 2015 한국축산식품학회지 Vol.35 No.1

A lactic acid bacterium presenting antimicrobial activity against a Lactobacillus acidophilus strain used for eradication of acid inhibition was isolated from a natural cheese. The 16S rRNA gene sequence of the isolate best matched with a strain of L. rhamnosus and was designated L. rhamnosus CJNU 0519. The antimicrobial activity of the partially purified bacteriocin of CJNU 0519 was abolished when treated with a protease, indicating the protein nature of the bacteriocin. The partially purified bacteriocin (rhamnocin 519) displayed a narrow antimicrobial activity against L. acidophilus, Listeria monocytogenes, and Staphylococcus aureus among several tested bacterial and yeast strains. Rhamnocin 519 in particular showed strong bactericidal action against L. monocytogenes.
