‘Bristol Fairy’ 유래의 결실되는 아조변이체인 ‘Gyp99’의 실생계통으로 밝은 백색 겹꽃에 소화가 큰 ‘Gyp06-11’로부터 2008년 특성이 우수한 ‘Gyp08-2’ 계통을 선발하여 2009-2010년 2년 동안 특성평가 및 특성검정을 통해 ‘Dream Song’을 육성하였다. ‘Dream Song’의 초형은 직립형이고, 잎 모양은 피침형, 소화는 꽃잎수가 많고 암술이 2개인 백색겹꽃으로 꽃잎은 도란형, 꽃잎 끝 모양은 약간 둥근형, 꽃받침 모양은 컵형인 ‘Dream Song’ 고유의 특성을 가진다. 또한 소화의 일시개화성이 우수하고 절화수명이 매우 길며, 분지각이 작고 흰가루병에 강하고 총체벌레와 잎굴파리 등 충해에도 강해 재배적 가치가 높은 특성을 가진다. 준고냉지 여름절화 작형에서 ‘Dream Song’ 개화는 ‘Bristol Fairy’보다 17일 늦고 절간장과 화경장이 길었으며, 측지 분화가 많고 줄기가 굵었다. 또한 소화가 크고 야간 기온 22℃, 7일 이상의 고온조건에서도 기형화 발생이 없었다. ‘Dream Song’ is a cultivar of Gypsophila paniculata developed by the Jeollabuk-do Agricultural Research & Extension Services in 2010 for cut-flower production. This hybrid was bred from 121 seedlings collected from an open-pollinated population of ‘Gyp06-11’. It has novel morphological characteristics of upright plant type, lanceolate leaves, double florets with a few bright white-colored petals of obovate shape, truncate petal tips, and cup-shaped calyces. Furthermore ‘Dream Song’ has desirable cultivation characteristics including narrow branching angle, and moderate resistance to powdery mildew, thrips and leaf miners. Moreover it produces more primary branches, and longer internodes and flower stalks than reference cultivar ‘Bristol Fairy’ during summer cultivation in a subalpine area (500 m over the sea level). Flowering in ‘Dream Song’ is delayed by about 17 days as compared to ‘Bristol Fairy’. ‘Dream Song’ produces normal flowers with 2 pistils and an average of 10.4 stamens, with fewer malformed flowers than ‘Bristol Fairy’.

강금만(Kang, Kum-man),김민재(Kim, Min-jae),송영수(Song, Youngsoo) 한국경영교육학회 2020 경영교육연구 Vol.35 No.6

[연구목적] 학습민첩성은 Lombardo and Eichinger(2000)가 그 개념을 최초로 주창한 이래 다양한 관점에서 개념정의와 구성요인 연구가 이루어졌으나 국내기업에의 적용을 위한 목적에서의 연구는 상대적으로 미흡하였다. 이에 실천적 관점에서 국내기업에의 적용을 위한 학습민첩성의 개념정의와 구성요인을 탐색해보고 시사점을 제공하고자 하였다. [연구방법] 본 연구는 선행연구에 대한 문헌고찰, 국내 인적자원개발 관련 산학연 전문가를 활용한 델파이 기법, 초점집단면접을 연구방법으로 채택함으로써 삼각검증을 실시하였다. 먼저 문헌고찰을 통해 사전적 구성요인을 도출하였고, 산학연 전문가 23명으로부터 3차에 걸친 델파이조사를 통하여 개념정의와 구성요인을 확인하였고, 2차와 3차 델파이조사 뒤에 초점집단면접을 실시하여 최종적인 개념정의와 구성요인을 확정하였다. 이 과정에서 내용타당도비율(CVR)을 파악하여 델파이조사의 타당도를 검토하였다. [연구결과] 국내기업에의 실질적 적용을 위한 학습민첩성의 개념적 정의에 있어서 포괄적 접근 관점에서의 개념정의가 이루어졌다. 구성요인은 크게 성장지향, 자아성찰, 관계지향, 변화지향, 유연한 사고, 도전적 실험의 6개가 도출되었다. [연구의 시사점] 학습민첩성 구성요인을 확인함으로써 실천적 관점에서의 교육과정 개발과 상관관계 분석을 위한 토대를 제공할 수 있다. [Purpose] Since Lombardo and Eichinger(2000) advocated the concept of learning agility, a lot of studies had been conducted worldwide. But the research for the purpose of applying to Korean companies is relatively insufficient. The purpose of this study is to explore the conceptual definition and constructs of learning agility from a practical point of view. [Methodology] For this purpose, we conducted triangulation by adopting literature review, 3-round Delphi method, and 2-round focus group interview. 23 experts from universities, research institutes and industries participated in the Delphi survey. CVR(Content Validity Ratio) was used as a criteria for the selection of constructs. [Findings] The characteristic of learning agility concept derived from Delphi method and FGI is that it takes the comprehensive approach. 6 major constructs of growth-oriented, self-reflective, relationship-oriented, change-oriented, flexible thinking, and challenging experiments are derived. [Implications] Identified constructs provide a foundation for curriculum development and correlation analysis from a practical perspective. As a result, it can help reinforce learning agility in Korean companies.

Case Report : Hepatoid Carcinoma of the Pancreas Combined with Neuroendocrine Carcinoma

( Ji Ye Jung ),( Yoon Jae Kim ),( Hee Man Kim ),( Hong Jeoung Kim ),( Seung Woo Park ),( Si Young Song ),( Jae Bock Chung ),( Chang Moo Kang ),( Joo Yeon Pyo ),( Woo Ick Yang ),( Seung Min Bang ) The Editorial Office of Gut and Liver 2010 Gut and Liver Vol.4 No.1

Hepatoid carcinoma is a primary extrahepatic carcinoma whose morphology, immunohistochemistry, and behavior are similar to those of hepatocellular carcinoma. The most common sites of extrahepatic carcinoma are the stomach and ovary, but nine cases of hepatocellular differentiation of the pancreas have been reported in the literature. We report another case of hepatoid carcinoma of the pancreas that was associated with the development of a pancreatic endocrine carcinoma in a 46-year-old man. Serum alpha-fetoprotein (AFP) was elevated to 262.49 IU/mL and radiological examinations revealed a mass measuring 7.5 cm in diameter in the head of the pancreas. He underwent a conventional Whipple operation, and light microscopy showed adenocarcinoma that was immunopositive for AFP, hepatocyte antigen, cytokeratin, chromogranin, synaptophysin, and alpha-1 antichymotrypsin. Although hepatoid differentiation was not shown unequivocally histologically, other immunohistochemistry findings supported the diagnosis of hepatoid carcinoma combined with neuroendocrine carcinoma. The patient was healthy and had no evidence of recurrence at 4 months after the surgery. This report describes why hepatoid carcinoma should be considered as a differential diagnosis of a pancreatic mass, especially when serum AFP is elevated. (Gut Liver 2010;4:98-102)

Bile duct web is very rare disease and it`s etiology is controversial. Some webs are occurred in the presence of chronic inflammation, frequently associated with bile duct stone, but others are thought to be congenital. Many patients with bile duct web are asymptomatic, but they sometimes present symptom of biliary obstruction and cholangitis. It can be diagnosed by endoscopic retrograde cholangiopancreatogram, typically appearing as thin and shelf like radiolucent ring. We report a case of the common bile duct web with bile duct stones diagnosed by Endoscopic retrograde cholangiopancreatography (ERCP) in a 65-year-old man. The patient was treated by balloon dilatation successfully.

Expression of stromal cell-derived factor-1α is an independent risk factor for lymph node metastasis in early gastric cancer

SONG, IK-CHAN,LIANG, ZHE-LONG,LEE, JUNG-CHAN,HUANG, SONG-MEI,KIM, HA-YON,OH, YOON-SUK,YUN, HWAN-JUNG,SUL, JI-YOUNG,JO, DEOG-YEON,KIM, SAMYONG,KIM, JIN-MAN,LEE, HYO-JIN Spandidos Publications 2011 Oncology letters Vol.2 No.6

<P>Lymph node metastasis is considered to be a significant prognostic factor for early gastric cancer (EGC). However, no real consensus exists on which patient and/or tumor characteristics are associated with lymph node metastasis. We investigated whether stromal cell-derived factor (SDF)-1α expression correlates with lymph node metastasis in patients with EGC by immunohistochemically examining the expression of SDF-1α in 138 archival tissue specimens of EGC. Of these specimens, 59 (42.8%) and 79 (57.2%) were grouped into SDF-1α-positive and SDF-1α-negative groups, respectively. No significant differences existed with respect to age, gender, tumor location, proportion of tumors >20 mm in size, macroscopic type, depth of invasion or histology between the SDF-1α-positive and -negative groups. However, the SDF-1α-positive group was significantly correlated with lymphovascular invasion and lymph node metastasis. Results of the univariate analyses indicated that lymphovascular invasion, undifferentiated histology and SDF-1α positivity were statistically significant risk factors affecting lymph node metastasis in patients with EGC. Multivariate analyses showed that lymphovascular invasion [hazard ratio (HR), 8.595; 95% confidence interval (CI), 1.694-43.595; P=0.009], undifferentiated histology (HR, 2.965; 95% CI, 1.037-8.471; P=0.043) and SDF-1α positivity (HR, 2.108; 95% CI, 1.316-10.135; P=0.013) were independent risk factors predicting lymph node metastasis in EGC. In conclusion, these results suggest that SDF-1α expression in tumor cells is a predictive marker of lymph node metastasis in EGC.</P>

Background: The Korea Interstitial Lung Disease Study Group has made a new nationwide idiopathic pulmonary fibrosis (IPF) registry because the routine clinical practice has changed due to new guidelines and newly developed antifibrotic agents in the recent decade. The aim of this study was to describe recent clinical characteristics of Korean IPF patients.Methods: Both newly diagnosed and following IPF patients diagnosed after the previous registry in 2008 were enrolled. Survival analysis was only conducted for patients diagnosed with IPF after 2016 because antifibrotic agents started to be covered by medical insurance of Korea in October 2015.Results: A total of 2,139 patients were analyzed. Their mean age at diagnosis was 67.4±9.3 years. Of these patients, 76.1% were males, 71.0% were ever-smokers, 14.4% were asymptomatic at the time of diagnosis, and 56.9% were at gender-agephysiology stage I. Occupational toxic material exposure was reported in 534 patients. The mean forced vital capacity was 74.6% and the diffusing capacity for carbon monoxide was 63.6%. Treatment with pirfenidone was increased over time: 62.4% of IPF patients were treated with pirfenidone initially. And 79.2% of patients were treated with antifiboritics for more than three months during the course of the disease since 2016. Old age, acute exacerbation, treatment without antifibrotics, and exposure to wood and stone dust were associated with higher mortality.Conclusion: In the recent Korean IPF registry, the percentage of IPF patients treated with antifibrotics was increased compared to that in the previous IPF registry. Old age, acute exacerbation, treatment without antifibrotics, and exposure to wood and stone dust were associated with higher mortality.

A Study on Brand Extension and Cannibalization of Color Cosmetics

Man Seok Song,Yun-Jae Cho,Mi Ju Yim 한국피부과학연구원 2020 아시안뷰티화장품학술지 Vol.18 No.4

목적: 최근 국내 색조화장품 시장 규모와 수요의 평균 성장률이 점차 증가하고 있으며, 색조화장품 브랜드간의 경쟁 또한 심화되고 있다. 이러한 가운데 브랜드 포트폴리오 확장전략으로 하향확장된 대기업 계열 화장품 기업들은 새로운 색조화장품을 개발하여 시 장에 출시하고 있으나 그 성과에 대한 실효성이 의문시되고 있다. 잘못된 브랜드 확장은 기존 브랜드에 대한 전반적인 이미지의 실 패와 함께 패밀리 브랜드간의 자기시장잠식 현상 발생하여 기업 전반에 걸친 매출액 감소와 함께 시장효율이 저하되는 치명적인 손 실을 갖는 최악의 상황을 맞게 된다. 방법: 본 연구에서는 색조화장품 시장에서 모기업을 중심으로 확장된 패밀리 화장품 기업에서 출시한 색조화장품의 자기시장잠식 현상을 파악하기 위해 Bass 확산모형과 지각도 분석 그리고 교차분석을 도입하여 자기시장잠 식 분석을 실시하고자 한다. 색조화장품을 사용하고 있는 여대생을 대상으로 286부의 설문지를 수집하여 SPSS사의 통계 패키지 프 로그램으로 빈도분석을 실시하여 인구통계적 분석과 biplot 분석을 실시하여 지각도 분석을 실시하였으며, 그리고 교차분석을 실시 하여 평가대안 색조화장품 브랜드에 대한 충성도, 전환의도, 이탈율, 미래시장 점유율 분석과 함께 자기시장잠식 현상을 파악하였 다. 그리고 연구 대상 평가대안 기업의 시계열 자료를 이용하여 Bass 확산모형 분석을 실시하여 자기시장잠식을 분석하였다. 결과: 자기시장잠식 분석을 위한 Bass 확산모형의 분석결과 두 개의 패밀리 그룹에서 모두 발생되어지는 것으로 나타났으며, 이들 모두 의 모방계수의 값이 혁신계수의 값보다 높게 나타나 진입비용이 증가하게 되며 신상품 전파에 있어서 구전의 영향력이 높아진다고 할 수 있다. 그리고 지각도 분석에서는 에이블씨엔씨 화장품의 미샤와 어퓨의 색조화장품 브랜드에서만 자기시장잠식 현상이 발생 하는 것으로 나타났다. 그러므로 이들 평가대안으로부터 근접하게 붙어 있는 평가요소의 차별화를 통하여 자기시장잠식 현상을 최 소화하여야 할 것이다. 교차분석에서도 평가대안 모두에게서 자기시장잠식 현상이 발생하는 것으로 나타났으며, 어퓨의 경우 가장 낮은 충성도를 보이고 있었으며 신규고객유입률은 높은 것으로 나타났다. 이니스프리의 경우 현재시장점유율뿐만 아니라 단기미래 시장점유율도 가장 높은 것으로 나타났으며 충성고객률 또한 가장 높은 것으로 나타났다. 결론: 색조화장품 시장에서 자기시장잠 식 분석을 위해 실행한 본 연구에서 평가대안으로 선정한 두 개의 패밀리 그룹에서 자기시장잠식이 발생하는 것으로 분석되어져 나 타났다. 자기시장잠식 분석을 위해 잘 알려져 있는 Bass 확산모형의 도입과 함께 보완적 분석방법으로 도입한 대응일치 분석을 이 용한 지각도 분석과 교차분석을 이용한 자기시장잠식 분석은 본 연구에서만 아니라 다른 연구 분야에서도 유용하게 적용할 수 있을 것으로 기대할 수 있다. 이러한 색조화장품 시장에서의 자기시장잠식 분석을 위한 연구 분석 결과는 격심한 경쟁구조에서 확장된 브랜드 포트폴리오의 성과 측정, 신제품 출시뿐만 아니라 브랜드의 신규시장 진출, 경쟁브랜드와의 시장경쟁구조분석 그리고 자기 시장잠식 방어전략의 제시 등 다양한 분야에 적용 가능한 시사점을 제시할 수 있다. Purpose: TIncorrect brand expansion could cause image failure of existing brands and create cannibalization among family brands. It could reduce sales and decrease market efficiency, bringing about a worst-case fatal loss scenario. Methods: This study used the Bass diffusion model, positioning map analysis, and cannibalization analysis by introducing a cross analysis to understand the cannibalization phenomenon within the field of color cosmetics. Specifically, we focused on subsidiaries of a big cosmetics company. We administered questionnaires to 286 female college students who used color cosmetics. We then performed a frequency analysis using the Statistical Package for the Social Sciences to carry out a demographic statistical analysis and biplot analysis. We also performed positioning map analysis and cross analysis to understand color cosmetics brand loyalty, transfer intention, breakaway rate, future market share rate, and the cannibalization phenomenon. Results: The Bass Diffusion Model for cannibalization analysis showed that cannibalization was present throughout all family groups. The cannibalization phenomenon happened only at MISSHA and A'fieu color cosmetics of Able C&C cosmetics brand, according to positioning map analysis. All of the cross-analysis estimation alternatives exhibited a cannibalization phenomenon. Conclusion: These results hold implications for expanded brand portfolio performance measures in an intensely competitive market, launching new products, launching new brands in the new market, analyzing the market competition structure with competitive brands, and developing strategies to defend cannibalization.
