본 연구는 중국내 모바일 전자상거래를 이용하여 구매하는 e-고객이 소비자 측면에서 전자상거래 업체의고객니즈관리에 대한 질적 향상을 위한 e-고객니즈관리 측정 모형을 탐색하고자 하였다. 모바일 전자상거래의고객니즈관리에 관한 문헌고찰을 통하여 설문지를 개발하였으며 온라인 설문조사를 실시하여 새로운 변수개발에 적합한 PLS 분석법을 적용하여 수집된 데이터를 제안된 예측연구모델에 적합한가의 여부를 검증하였다. 모바일 전자상거래만을 사용하여 구매활동을 하는 99명의 유효한 중국인 대상 표본을 추출하였으며, 고객니즈관리 측정모형 분석을 위한 분석 도구로 20문항으로 구성된 설문지를 제작하여 사용하였으며, 수집된자료는 SmartPLS 3.0을 이용하여 분석하였다. 분석결과 e-고객니즈관리를 구성하는 고객니즈이해, 고객니즈파악, 고객응대, 고객소통의 1차순 구성개념들은 반영지표(mode A)로 구성이 되었으며 구성개념들 모두 e-고객니즈관리를 예측하는 조형지표(mode B)로 구성이 되는 반영-조형 모형Ⅱ로 구성이 됨을 CTA-PLS 접근법을통하여 검증하였다. 중국 전자상거래의 구매행위에 영향을 미치는 e-고객마케팅 관점에서 데이터 기반의실증자료를 제시함으로써 e-고객니즈관리에 영향관계를 파악할 수 있는 구조모델구축에 기초적인 참고자료를 제시하고자 하였다. This study aims to explore measurement model of e-customers management for improving the quality of e-commerce company's customer needs management in the perspectives of e-consumers. The questionnaire was developed through literature review on customer needs management of mobile e-commerce, and online survey was conducted to verify whether the collected data is suitable for the proposed predictive model by applying the PLS analysis method which is suitable for new variable development. The valid samples of 99 Chinese people who are engaged in purchasing activities using only mobile e-commerce were extracted, and a questionnaire consisting of 20 items was produced as an analysis tool for analyzing the e-customer needs management measurement model. The collected data were analyzed using SmartPLS 3.0. As a result, the first-order constructs of understanding customer needs, identifying customer needs, customer response, and customer communication that constitute e-customer needs management are represented as reflection indicators (mode A). The CTA-PLS approach verified a reflection-formative type Ⅱ model that consists of formative indicators (mode B) that predict perceived e-customer needs management. By presenting data-based empirical data from the perspective of e-customer marketing that affects the purchasing behavior of Chinese e-commerce, this study contribute to provide basic reference data for constructing a structural model that can identify the relationship of e-customer needs management

하구퇴적토 환경에서 E.coli의 부착에 영향을 주는 물리화학적 요인

이건형 한국미생물학회 1988 미생물학회지 Vol.26 No.3

The higher bacterial numbers on clay than on sand were caused by different environmental factors. Such factors affecting the adsorption of E. coli ATCC 11775 in the sediment as follows; optimal pH range for the adsorption of E. coli ATCC 11775 was pH 7.5-pH 9.5. E. coli ATCC 11775 were shown maxima in the salinity of 18.$75%_{o}$ on sand type sediment and $12.5%_{o}$ on clay type sediment. Bacteria attached better to clay typed sediment than to sand typed sediment when organic substance was eliminated. Beef extract of 0.5%-1% concentration was found to promote the attachment of E. coli ATCC 11775 effectively. Peptone of 0.5% was enganced the attachment on the clay, and peptone of 1.3%-5%, on the sand. E. coli ATCC 11775 was found to adsorb onto benthonite with the highest efficiency and on celite with the lowest efficiency. Efficiency of adsorption by inorganic ions was shown due to higher values of ion. Adsorption was achieved in the order of $Al^{3+}, Ca^{2+}, Na^{+}$.

金烏山城과 天生山城의 硏究

李建衡 대구교육대학교 1976 論文集 Vol.12 No.-

An old fortress of Goryeo, Geumo and Cheonseng Hill Fortress were repaired the begining of Choseon Dynasity(early in 1th century), used a strategic point of national defence again. They were ruined before end of 15th century for contempt of national defence strategy due to peace of long period. When occured suddenly the Hideyoshi's invasion(1592~1596) they emphasized of the importance of both the fortresses and repaired again Geumo 1595, Cheonseng 1596, and performed their impotant misson for the defence of Yeongnam province, when happened the Hideyoshi's twice invasion(1597~1598). Hereafter Cheonseng built the outer fort by Gwag Jae-U(Challisa) in 1604 and Geumo built the outer fort by Lee Myeong-Ung (Governer of Gyeongsang privince) in 1963 after occured of the Jurchin's invasion (1636~1637). At the beginning of 18th century according to reinforce of the national defence strategy, Geumo fortress promoted 'Dogjin'(an important military strategic place) and dispositioned about 3,500 soldiers and brought into full play of his military functions to the end of Choseon Dynasty by Continuous interest and protect of it. But Cheonseng fortress decrease of his value. I suppose, it was the reason that the Gasan Hill Fortress in Chilgog county was built at the middle of the 17th century more larger scale and had better conditions than Cheonseng fortress. Cheonseng Hill Fortress was not ruined but displayed of his function of speare hill fortress of emergency. Both the hill fortresses were located along side of the Nagdong river, on the main street to Seoul from Yeongnam and gain control of it. Also we knew they were natural fortress because have steep terrain, wide field and villages under the castle wall. But Cheonseng Hill Fortress which has narrow width and lack water more valuneless than Geumo. Geumo and Cheonseng Hill Fortress are very meaningful historical relics to contriuted defence of mother land against for enemy from Goryeo to the end of Choseon when we think historical origin and military point of view.

Fast and sensitive fluorescent detection of organic mercury species using fluorescent probe based on arylboronic acids

이건형 한국공업화학회 2020 한국공업화학회 연구논문 초록집 Vol.2020 No.-

Aryl boronic acids that were used as important building blocks in organic synthesis have been widely employed in carbohydrate detection, H2O2 sensing, protease enzyme inhibitors, anticancer agents, and drug delivery systems. We present a new fluorescent probe (1) based on the fast displacement reaction of arylboronic acid with inorganic and organic mercury species in purely aqueous solution and live cells. 1 recognized Hg2+ and methylmercury by turn-on responses through the irreversible chemical reaction of the arylboronic acid moiety with the mercury species. 1 showed promising sensing properties for mercury ions such as low detec-tion limit (1.82 nM, 0.36 ppb), high selectivity and sensitivity, fast reaction (< 2 mins), and operation in purely aqueous solutions and live cell.

大邱의 變遷 : 三國時代에서 高麗까지 From the Three Kingdoms Period to the Koryo dynasty

李建衡 대구교육대학교 1968 論文集 Vol.4 No.-

Situated in a place with such favorable conditions for the appearance of a village as river, fertile plain and basin which facilitate transportation, production and defence of enemies, Taegu had seen a primitive village formed in it from the prehistoric age. The distribution of prehistoric relics and Dolmens which were found in the vicinity of Taegu City tells that this village had been considerably developed during the Neolithic and Aeneolithic ages. With the onset of the Three Kingdoms period, a large tribal state was appeared. Located at a key point of transportation covering Keum-ho river valley through River Naktong, Taegu had been the heart of transportation and the military base for Silla's advance into Kaya or Paekche-that is. an apple of their eyes which caused many conflicts between themselves. But as the two came under the control of Silla, much development was made and this is proved by the ancient tombs in the surrounding areas of Taegu City. Though not materialized, an attempt was made to transfer the capital city to Taegu at the period of the United Silla. Around the end, Taegu was the scene of competitions for the throne among aristocrats and wars between the Late paekche an6 Koryo. These events are considered resulting from the importance of Taegu in the light of transportation and armed forces. With the dawn of the Koryo dynasty, along with the transfer of capital, attention was given to the northern parts-Kihtan and Jurchen. This lessened concern toward the south and retarded the development of Taegu. But at the early stage, noticeable advance is seen in the records of storing the Buddist Tripitaka in the Buin temple or being promoted to Hyen-Ryong (an administrative unit equal to Gun). After the middle stage, the city and inhabitants were suffered by the foreign invaders such as Mongol and Japanese pirates. With all the weakened concern and the loss of transportation initiative, Taegu went through gradual expansion and was promoted to Gun at the early period of Yi dynasty. This development may be indebted to the natural conditions Taegu has had.

자연생태계에서의 유전물질의 전이

이건형 한국미생물학회 1990 微生物과 産業 Vol.16 No.3

Avery, MacLeod, McCarty가 1944년에 세균에서 유전적 재조합이 이루어진다는 사실을 발견한 후 세균은 진화 학자들과 미생물 학자들로 부터 주목을 받기 시작했다. 왜냐하면 세균은 자연생태계에서 또다른 형태의 유전적 적응성을 지니고 그러한 돌영변이 중 일부는 모세포(parent cell)보다도 주변환경에 더 잘 적응되었기 때문이다. 이제까지 GEM들이 생태계에서 유전자들 전이시키는 빈도가 대부분 낮았고, 토양이나 다른 자연생태계애서 유전자의 전이가 지속적으로 일어난다는 실험적 증거는 없었지만 이들을 생태계에 방출한 결과 유전자 전이가 몇몇 실험에서 확인된 적이 있어 토양에서의 유전적 전이의 가능성을 강하게 암시하고 있다. 하지만 어떻게 전이되고 토양의 물리, 화학및 전이에 필요한 최소한의 donor와 recipient의 수와 정확한 감지 방법등이 아직까지 밝혀져 있지 않은 상태이다. 더우기 토양환경에서 미생물의 활성과 생태, 군집 동태에 영향을 줄 수 있는 기능을 나타내려면 얼마만큼의 재조합 세균이 단위면적당 필요한지도 밝혀지지 않은 상태이다. 따라서 이러한 여러가지 문제점을 밝히는 것은 학문적인면 뿐만 아니라 진화론적인 이론에도 도움이 되며 GEM들이 토양이나 다른 생태계에 유출되었을 때의 환경영향평가나 규제를 하는데에도 도움이 될 수 있다고 본다.
