문헌을 통해 본 우리나라 커피의 역사 -개화기와 일제시대를 중심으로-

이 논문은 커피가 우리의 역사 속으로 어떻게 들어오게 되었고, 우리문화 속에 어떻게 자리매김하게 되었으며, 어떠한 방식으로 전개되었는지 그 연원을 추적해보고자 하는데 목적을 두었다. 우리나라 개화기 커피의 유입과정은 청나라를 통해 유입되었을 가능성이 매우 크다. 그러나 외교사절단이나 선교사 혹은 일본을 통해서 우리나라 고위관료들이 커피문화를 이미 접하고 유입했을 가능성에 대해서도 열어두어야 할 것이다. 청일전쟁 이후 커피문화의 정착과 전개과정에서 있어서는 일본의 영향이 컸으며, 대한제국기 이전에 궁중에서는 커피를 비롯한 서양문화가 이미 자리 잡고 있었다. 일제시대는 커피문화의 발전기라고 할 수 있으나 여전히 커피를 접할 수 있는 대상은 특권층으로 제한적일 수밖에 없었다. 1920년대에는 커피를 전문적으로 파는 다방이나 카페가 등장하였고, 커피문화는 1930년대 모던걸모던보이의 상징이 되었으며 문화교류의 장으로 활용되었다. 그러나 브라질의 커피 수출 통제와 1940년대 태평양전쟁으로 커피 수입의 경로가 막히면서 다방과 카페는 폐업을 하거나 전업을 할 수 밖에 없었다. This study intends to track down the way coffee was first introduced and established in Korea. Coffee was most likely introduced by the Qing Dynasty. However, there is still a possibility that the inflow of the coffee culture was encouraged by diplomatic missions or missionaries through Japan. After the Sino-Japanese War, Japanese influence was extensive and the settlement and development of coffee culture and western culture, including coffee, became rooted at the royal court. The Japanese colonial period can be considered as a time of rapid growth in coffee culture, but coffee was still restricted to the privileged class. In the 1920s, tea rooms and cafes where people could drink coffee emerged as a center of social intercourse and the coffee culture became a symbol of modernization. However, most tea rooms and cafes had to close down due to regulations on Brazilian coffee exports and the Pacific War in the 1940s.

The proper harvester(Camp champion C 3000) equip condition to get under 5mm Kenaf(Hibiscus cannabinus L.) harvesting particle size were set the number of blade more than 4 and rotate over 100 rpm. The small size of harvesting particle could promote the fermentation of lactobacillus and it improved the exterior and chemical evaluation of kenaf silage. The fittest fermentation periods to sustain basic levels of kenaf silage quality was more than 40 days. To secure the most suitable stage for harvest, we analyzed yields, crude protein and total digestible nutrients contents along culture periods. At 120 days after seeding, kenaf yields approach 9,600 kg/10a and crude protein contents was 8.2% which belonged most preferable grade. also the total digestible nutrients reached 52.2%. In the process of kenaf fermentation, add molasses 0.5∼2.0% could strengthen the degradation of cellulose and elevate the preference of flavor. To select the best microbe for making kenaf silage, we applied the 4 kinds of lactobacillus which originated from Kimch and make an patent application by Jeonbuk ARES. As a result L. mesenteroides M-17 was sellected for enhancing the preference of flavor and sustaining the good grade silage quality. Adding L. mesenteroides M-17 in the process of fermentation could elevated the crude protein contents and get good grade of relative feed value.

본 연구의 목적은 확장계획행동이론을 이용한 커피전문점 이용고객에 대한 태도, 주관적 규범, 지각된 행동통제, 사전지식이 행동의도에 미치는 영향과 지각된 행동통제, 사전지식, 행동의도가 행동에 어떠한 영향을 미치는지 살펴보았다. 연구의 목적을 달성하기 위하여 커피전문점에서 커피를 구매하는 고객을 대상으로 설문조사를 실시하였고 회수된 350부의 설문지 중 불성실한 응답 11부를 제외한 339부를 분석에 사용하였다. 분석 결과, 커피전문점 이용고객의 태도, 주관적 규범, 지각된 행동통제, 사전지식이 행동의도에 유의한 영향을 미쳤다. 또한 지각된 행동통제와 행동의도가 행동에 유의한 영향을 미쳤으나, 사전지식의 경우 행동에 미치는 직접적 영향이 미약하였다. 이용고객이 커피전문점 관련 사전지식을 많이 보유하고 있더라도 환경적 요인과 상황적 요소에 따라 바로 행동을 취할 수 없기 때문인 것으로 판단되다. 본 연구의 시사점을 요약하면, 커피전문점은 이용고객을 유지하고 잠재고객을 유치하기 위해 이용고객들이 호의적인 태도를 가지도록 노력해야 한다. 또한 행동의도에 직접적인 영향을 미치는 지각된 행동통제 - 이용 용이성 및 가능성 등 - 커피전문점의 위치, 교통 등 시설 측면도 고려해야 한다. 사전지식은 행동에 대한 직접 효과가 미약하나 행동의도를 통한 간접 효과가 있는 주요 변인으로 이용고객의 사전지식을 확대 시킬 수 있는 노력이 필요하다. 최근 감성브랜드 및 스토어 어미지 등에 따라 구매하는 경향이 증가하므로 감성만족 요소들을 파악한 차별화된 마케팅 전략이 필요할 것이다. The purpose of this research lies in analyzing the effects of attitude, subjective regulations, perceived behavioral control, and prior knowledge on behavioral intentions for coffee shop customers, utilizing the Extended Theory of Planned Behavior. A survey was conducted of customers at coffee shops. A total of 350 questionnaires were collected. Excluding 11 undependable questionnaires, 339 questionnaires were used for analysis. The results show that respondents`` attitude, subjective regulations, perceived behavior control and preliminary knowledge had significant effects on behavior intentions. While respondents`` perceived behavioral control and behavioral intention had significant effects on behavior, prior knowledge did not significantly influence behavior. This implies that although customers have much knowledge about coffee shops, the environmental and situational elements more strongly influence their behavior. The results of this study propose implications that coffee shops should have friendly attitude towards customers in order to keep present customers and to attract potential customers. In addition, coffee shops should consider perceived behavioral control that has direct effects on behavioral intentions, such as convenience and possibility, as well as location and transportation. Although prior knowledge does not have significant effects on behavior, this factor is still important since it has indirect effect on behavior through behavioral intentions. Recently, it is suggested that purchase is affected by emotional brands and store images; therefore, a differentiated marketing strategy that considers such emotional satisfaction factors should be utilized.

저온저항성 유전자를 이용한 국화 형질전환

한수곤,최인영,강찬호,고복래,최정식,이왕휴,Han, Soo-Gon,Choi, In-Young,Kang, Chan-Ho,Ko, Bok-Rai,Choi, Joung-Sik,Lee, Wang-Hyu 한국식물생명공학회 2006 식물생명공학회지 Vol.33 No.1

저온저항성 BN115 gene과 표지유전자로서 kanamycin에 저항성 있는 nptII gene을 가지고 있는 식물발현용 binary vector pBin19/BNl15가 도입된 A. tumefacience MP90을 국화잎과 공동배양 하였다. 또한 particle bombardment를 이용하여 목적으로 하는 유전자가 식물체에 안정적으로 도입되어 발현됨을 PCR 및 Real-Time PCR 검정으로 확인하였다. 국화잎과 공동배양에 사용된 Agrobacterium은 $5.0{\times}1.0{\mu}m$로 non-sporing, motile, rod 형이며, Callus는 pin이나 cork-borer에 의해 상처 난 잎 가장자리로부터 형성되어 식물체가 재분화 되었다. 유전자 도입조건은 Agrobacterium을$O.D._{600}{\approx}0.5$에서 20분간 공동배양 할 때, Particle bombardment는 helium 압력을 1,100 psi, target 거리를 9 cm로 유지했을 때, 가장 효율이 높았다. 5mg/L kanamycin이 들어 있는 배지에서 선발된 형질전환체는 PCR 분석으로 형질전환여부를 판별할 수 있었으며, 선발 10개체 중 9개체에서 purified pBN115와 같은 크기의 밴드가 형성되었다. Taq-Man probe를 이용한 Real-Time PCR 결과 $45{\sim}0.00045ng/{\mu}{\ell}$ 범위에서 pBN115 gene을 10배씩 serial dilution한 amplification plot는 일정한 간격으로 standard curve를 보였으며, slope는 -3.313975, R2는 0.998319이었다. Amplification plots의 형질전환체 $C_T$값은 $20.75{\sim}33.81$범위였으며, 유전자 copy수는 정량분석을 기초로 산출하였다. pBN115의 plasmid DNA를 serial dilution했을 때, standard는 $5.6{\times}10^{10}/45ng{\sim} 5.6{\times}10^5/0.00045ng\;copies/{\mu}{\ell}$이 었으며, 형질전환체는 $3.86{\times}10^8{\sim}12565.71 copies/{\mu}{\ell}$이었다. 따라서 PCR, Real-Time PCR 분석 결과 저온저항성 유전자가 국화의 genome에 안정적으로 도입되었음이 확인되었다. With the use of Agrobacterium and gene-gun, cold regulated gene (BN115) has been injected in Chrysanthemum leaf disc and transgenic plants have been produced successfully on the selection media containing phytohormone. To determine the presence of the transferred cold regulated gene (BN115) in the transgenic Chrysanthemum, PCR-amplification indicated the presence of that gene. Real-Time PCR for confirmation of the putative transgenic plants was established. The copy number of cold regulated gene (BN115) is extrapolated on the basis of a standard curve. Serial dilutions of known number of gene copies were in triplicates. In this diagram, PCR cycles are plotted against the fluorescence intensity. The cycle at which the fluorescence reaches a threshold cycle is inversely proportional to the starting amount of target DNA.

In this paper, active forward converter with snubber circuit - composed of a tapped inductor, a snubber capacitor, two diodes - is proposed. By adding the snubber circuit, ZVS operation became possible even in a smaller magnetizing current conditions than the conventional converter. The operational principles and the equivalent mode analysis of the proposed converter is described and compared to conventional converter. We constructed the prototype active clamped forward converter with 300W output capacity and verified that efficiency of the proposed converter is higher than the conventional converter.
