극장의 매니저가 고객의 의향을 미리 예측할 수 있다면 고객에게 보다 만족스런 서비스를 제공함으로써 고객의 문화 복지를 향상시키고, 극장의 수익증진까지 기대할 수 있다. 이에 고객 행태를 분석하기 위한 서비스마케팅 관련 연구는 끊임없이 진행되고 있다. 본 연구는 공연예술서비스 마켓을 중심으로, 이 시장에서 이루어지는 고객의 재 구매 의사결정의 진행과정과 그 구조 를 ‘구조모형모델’을 이용하여 분석해 보고자 한다. 특히 재 구매결정에 있어 고객의 감정적 평가가 가지는 영향력이 보 다 강력하고 복잡하게 작용하는 공연예술시장만의 특수성과 현 시점의 시대적 상황을 고려해, 이제껏 시도해 보지 않았 던 ‘문화적인 경험’이란 새로운 개념을 독립적 변수로 추가 도입하였다. 공연예술시장에서 재 구매 의향을 이루어내는 기존 구성개념에 새로운 개념을 더해, 각 구성개념간 상호관계를 이해 하고, 재 구매 의도 파악의 구성개념에 대한 또 다른 접근법을 제시, 그 실제적 효용가치를 검증하고자 하였다. 이를 통 해 기존의 공연예술 서비스 품질관련 연구를 실증분석을 토대로 보강하고, 새로운 접근방법 구현을 실체화 하고자 한다. 이를 위해 유럽 최대 공연시장이라 할 수 있는 ‘Fringe Festival’에서 한국공연을 관람한 다국적 고객을 대상으로 직접 설문조사를 실시하였고, 총 36개국, 총 인원 568명의 다양한 정보를 수집하였으며, ‘AMOS 7.0 소프트웨어’를 이용하여 구조방정식 모형분석을 실시하였다. 연구분석 결과, 공연관객들의 ‘문화적 경험’이 고객의 재 구매 의사결정에 유의미한 영향을 미치고 있음을 확인하고, 그 영향의 통계적 결과치를 산출할 수 있게 되었다. 이로써 공연예술시장의 고객의사결정 모형에서 문화적 경험효과를 찾아내 재조명하고, 또 이러한 문화적 경험효과의 영향력을 실체화 할 수 있게 되었다. Many managers predict and assume their audiences’ behavior for developing sum of profit and boosting cultural welfare or service quality. In service marketing studies, customer satisfaction and repurchase intention has exhaustively studied and clarified the pathway of customer behavior. However when audiences make a decision, their pathway seems different with customers in normal service markets. Using the structure model, we explore how audiences make decisions to repurchase in the performing arts market. To predict on the audience’s desire to repurchase with merging new conceptual ideas, cultural experience is explored as something emotionally charged and complex in services in the performing arts. This research will seek to build a model and tests the interrelationship of the constructs in predicting repurchase intention in a performing arts market. A survey instrument has been designed based on European audiences who attending Korean performing arts in world biggest performing arts market, Edinburgh festival fringe. Over 36 different countries’ 568 respondents results have processed by utilizing a Structural equation modeling (SEM) of AMOS 7.0 software. The result shows that cultural experience significantly influences audience behavior intention and gives us the suggestion of how the impacts of cultural experience occur on the audience’s decision-making process within emotional appraising. This result approves that the cultural performing arts service is a complex service and it needs special attention for understanding their audience behavior unlike typical services.

Seonjeong Lee,Imbunm Kim,Hee-Dae Kwon,Dongwoo Sheen 한국산업응용수학회 2011 한국산업응용수학회 학술대회 논문집 Vol.6 No.1

A mathematical model which consists of a set of differential equations is widely used in many scientific fields. However, the inverse problem, the problem of parameter estimation based on the measurements of output variables, has not been well explored, although some least squares based approaches have been proposed and studied. It happens frequently that the model equations contain a number of unknown parameters. The aim of parameter estimation problem is to determine these unknown parameters. To do that, one formulates an appropriate constrained optimization problem to minimize the error between the measurements from the laboratory or the plant and the theoretical results obtained by solving the set of differential equations. In this talk, we will concerned with the problem of fitting a mathematical model involving a parameter function to given data. We focus on the case where the mathematical model is a linear differential equation and the parameter function is a piecewise constant function. We will propose the sufficient and necessary conditions for the given data set to derive the parameter function which fits the corresponding solution to the data set. Moreover, we suggest an algorithm for parameter function estimation in the case where the subintervals for piecewise constant function are yet to be determined.

Seonjeong Kim,Eunju Park,Jae-Hee Park 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

Calcium is one of the most important nutrients that determines the quality of life of the elderly. The purpose of this study was to evaluate the effect of calcium-balanced beverage (CBB) intake in healthy elderly to meet the recommended daily calcium intake. This study was performed crossover clinical trial and analyzed the antioxidant status and immune-related biomarker (age above 65 years, n = 8, 3 males and 5 females). Subjects did not take CBB for 0-3 wk and took it for 3-6 wk. CBB supplementation decreased insulin levels (Δ3-6 wk: 1.19±0.65 mg/dL → Δ0-3 wk: -0.58±0.38 mg/dL). Increasing degree of fasting blood glucose level was suppressed by intake of CBB, but this was not statistically significant. Catalase significantly increased by CBB supplementation (Δ3-6 wk: 3.50±5.30 K g/Hb) when compared with no supplementation period (Δ0-3 wk: -12.48±4.37 K g/Hb). However, superoxide dismutase and glutathione-peroxidase was not significant difference between 0-3 wk and 3-6 wk. Consequently, this study confirmed that calcium balanced beverage has beneficial effect on insulin sensitivity and some antioxidant enzymes in elderly.

The purpose of this study was to evaluate the effect of consuming a protein-balanced beverage (PBB) to meet the recommended daily protein intake in healthy elderly. This study was performed crossover clinical trial and analyzed the antioxidant status and immune-related biomarker (age above 65 years, n=9, 2 males and 7 females). Subjects did not consume PBB for 0 to 3 wk, and consumed it for 3 to 6 wk. In erythrocyte, glutathione-peroxidase activity was significantly lower in 3-6 wk than 0-3 wk (-5.60±2.18 vs 2.80±1.72 U g/Hb, p=0.008). However, superoxide dismutase and catalase was not significant difference between 0-3 wk and 3-6 wk. IL-10 increased significantly in 3-6 wk, compared with 0-3 wk (5.20±2.73 vs -17.40±9.92 pg/mL, p=0.043). PBB intake reduced the serum CRP concentration(80.21±36.91 → -88.84±46.88 pg/mL, p=0.012) and H₂O₂-induced DNA oxidative damage (-1.53±0.68 → -4.54±0.64, p=0.001). Accordingly, this study suggests that adequate protein intake in the elderly might positively improve antioxidant metabolism and immune-related biomarkers.

인수공통 호흡기바이러스인 인플루엔자바이러스 감염으로 인해 공중보건과 가축산업에 심각한 피해가 지속적으로 발생하고 있다. 인플루엔자 백신 접종을 통해 항원형이 일치하는 바이러스 감염에 대해 우수한 방어면역을 제공하고 있으나, 효과적인 바이러스 감염 제어에는 여전히 큰 공백이 존재하고 있다. 다양한 항원형을 갖는 바이러스에 동시방어가 가능한 범용인플루엔자백신 개발과 함께 바이러스 치료효과를 제공하는 항바이러스제의 개발도 중요한 접근법으로 고려되고 있다. 현재 널리 사용되고 있는 인플루엔자 항바이러스제의 불완전한 치료효과와 내성바이러스의 출현 등의 문제들로 인해 식물 유래 천연물의 항바이러스 활성에 대한 관심이 증가하고 있다. 특히, 현재 진행 중인 코로나-19 팬데믹은 범용적인 항바이러스 활성을 갖는 안전하고 효과적인 항바이러스제 개발의 필요성을 뚜렷이 보여준다. 본 리뷰는 현재까지 보고된 천연물의 항인플루엔자바이러스 활성을 요약하였다. 또한, 항바이러스 활성을 갖는 천연물의 바이러스 사멸활성과 면역증강활성을 이용하는 신규 백신개발과 면역증강제 개발 가능성에 대해서도 분석하였다. Influenza viruses are zoonotic respiratory pathogens, and influenza infections have caused a substantial burden on public health systems and the livestock industry. Although currently approved seasonal influenza vaccines have shown potent protection efficacy against antigenically well-matched strains, there are considerable unmet needs for the efficient control of viral infections. Enormous efforts have been made to develop broadly protective universal influenza vaccines to tackle the huge levels of genetic diversity and variability of influenza viruses. In addition, antiviral drugs have been considered important interventions for the treatment of viral infections. The viral neuraminidase inhibitor oseltamivir is the most widely used antiviral medication to treat influenza A and influenza B viruses. However, unsatisfactory clinical outcomes resulting from side effects and the emergence of resistant variants have led to greater attention being paid to plants as a natural resource for anti-influenza drugs. In particular, the recent COVID-19 pandemic has underpinned the need for safe and effective antiviral drugs with a broad spectrum of antiviral activity to prevent the rapid spread of viruses among humans. This review outlines the results of the antiviral activities of various natural products isolated from plants against influenza viruses. Special focus is paid to the virucidal effects and the immune-enhancing effects of antiviral natural products, since the products have broad applications as inactivating agents for the preparation of inactivated vaccines and vaccine adjuvants.

ANTHROPOMORPHISM IN LUXURY GOODS AND LUXURY SERVICE BRAND EVALAUTIONS

Seonjeong Ally Lee,Haemoon Oh 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

Even though luxury brands embraced social media (Godey et al., 2016; Kim & Ko, 2012), research on the use of social media for luxury brand marketing is limited. Given the increasing popularity of social media, it is imperative to examine social media-based communication strategies for luxury brands to achieve desirable consumer evaluations of brands and advertising. This research explored the role of brand anthropomorphism strategies in social media in enhancing consumers’ advertising and brand evaluations. Specifically, this research investigated (1) the effects of verbal-based brand anthropomorphism in the luxury goods brand context (Study 1), (2) the effects of verbalbased brand anthropomorphism in the luxury service brand context (Study 2), and (3) the effects of verbal-based brand anthropomorphism cues (Study 3) on consumers’ luxury brand and advertising evaluations. Studies 1 and 2 both collectively examined the role of self-focused anthropomorphized brand effects in two different contexts. Consumers easily connect themselves with an anthropomorphized advertising, compared to an objectified advertising for luxury brands. Study 3 identified the fit between luxury brand type and an anthropomorphized brand cue to explore the effectiveness of brand anthropomorphism. Depending on the type of luxury brands, consumers processed anthropomorphized brand cues differently. Consumers favorably perceived the fit between luxury good brands and partner cues; on the other hand, consumers favorably perceived the fit between luxury service brands and servant cues. Results of this research contribute to the social media advertising and luxury brand marketing literature by clarifying the role of brand anthropomorphism in consumer-brand relationships as well as in brand-advertising relationships. Results also provide industry suggestions for delivering personified brand messages to have desirable consumer brand and advertising evaluations.

P-32 Prognostic Factors for Lung Cancer in Idiopathic Pulmonary Fibrosis

( Seonjeong Lee ),( Jisun Lee ),( Dong Soon Kim ),( Jin Woo Song ) 대한결핵 및 호흡기학회 2016 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.121 No.-

Background: Lung cancer in idiopathic pulmonary fibrosis (IPF) shows poorer prognosis than lung cancer without. However, prognostic factors for lung cancer in IPF are not well defined. Methods: Clinical data were retrospectively analyzed in 610 patients with lung cancer (IPF=122) diagnosed from 2007 to 2015 at Asan Medical Center. Lung cancer subjects without IPF (n=488) were randomly selected as controls from registry, matched by age, sex, histologic subtype, stage and date of diagnosis. Results: Median follow-up period was 16.0 months. IPF group showed more frequent cough (68.6 vs. 49.9%), dyspnea (70.1 vs. 31.5%) and location at lower lobe (61.1 vs. 45.2%) and lower FVC (72.9 vs. 80.4% predicted), DLco (53.3 v.s 72.7% predicted) and TLC (73.3 vs. 90.3% predicted) compared to non-IPF group (all p<0.05). IPF group had poorer prognosis (median survival: 12.0 vs. 22.0 months, p<0.001) compared to non-IPF group, however, in the case of stage 4 or small cell lung cancer, prognosis was not different. IPF was an independent prognostic factor (HR 1.578) for overall lung cancer, with ever-smoker (HR, 2.747), FVC (HR 0.987), DLco (HR 0.992) and advanced stage (HR, 3.539). Body mass index (HR,0.860) and walking distance of 6 minute walk test (HR 0.996) were independent prognostic factors for IPF group with advanced stage (HR 5.596). Conclusions: IPF group had more respiratory symptoms, lower pulmonary function and poorer prognosis compared to non-IPF group. Low BMI and short distance of 6MWT may imply poor prognosis in IPF group.
