경상대학교 교내에 설치되어 있는 1-2W형 온실을 대상으로 전기 방열기를 이용하여 국화 재배온실의 난방효과를 검토한 결과는 다음과 같다. 실험기간동안 최고, 평균 및 최저 외기온은 각각 -3.8~21.3℃, -5.2~16.1℃ 및 -12.5~14.4℃ 정도의 범위로 나타났으며, 온실 내외의 평균상대습도 각각 43.5~98.6% 및 35.2~100%로 나타났다. 12월 중순부터 2월 상순까지 최저 외기온은 대략 -5.0~-10.0℃ 전후로 나타나 진주기상대의 최근 자료와 비교하면 상대적으로 최저기온이 낮게 나타나는 경향이 있었다. 야간의 경우, 방열기 직하부의 엽온이 방열기 중간 지점에서 측정한 엽온 보다 크게 2~3℃정도 높게 나타나거나 또는 미미하지만 약간 높게 나타나는 경향이 있었다. 근권부의 경우, 직하부나 중간 지점에서의 온도 차이는 거의 없는 것으로 나타났고, 근권부의 최고온도와 기타 최고 온도의 발생 시점을 보면, 약 2시간정도의 지체현상이 있음을 알 수 있었다. 그리고 실험기간동안 난방에 소요된 총 소비전력량, 공급에너지 및 총 난방비는 각각 2,800kWh, 2,408,000kcal 및 112,000won 정도였다. 화석연료인 경유로 난방할 경우, 총 난방비는 224,500won 정도였다. 방열기를 이용하여 난방할 경우, 난방비를 약 50% 정도 줄일 수 있을 것으로 판단되었다. An analysis in heating effects of an electric radiator located in a 1-2W type chrysanthemum (3 cultivars) cultivation greenhouse installed in Gyeongsang National University drew the following conclusions. During the experiment period, the highest, average, and the lowest outside temperatures were in the ranges of -3.8~21.3℃, -5.2~16.1℃ and -12.5~14.4℃, respectively, and the average relative humidity inside and outside the greenhouses were in the ranges of 43.5~98.6% and 35.2~100%, respectively. From mid-December to early February, the lowest outside temperature was recorded as approximately -5.0~-10.0℃, which showed that it tended to be relatively lower than the temperatures recorded at the Jinju Meteorological Observatory. During the night, the leaf temperature measured directly under the radiator tended to be higher by 2~3℃ than that those at the middle point of the radiator, or higher by anegligible amount. In the case of root zone temperature, it was found that there was almost no difference between temperatures of the part directly under and the middle point, and the time when the highest temperature of root zone and other highest temperatures took place showed that there was about a 2-hour delay phenomenon. The total electricity consumption, energy supply and total heating cost during the experiment period were 2,800 kWh, 2,408,000 kcal and 112,000 won, respectively. When diesel, a kind of fossil fuel, was used as heating oil, the total heating cost was around 224,500 won. It was estimated that the total heating cost could be reduced by around 50% if a radiator was used.

The Purpose of this study was to identify decision-making styles of girls' high school students in buying apparels. A questionnaire, based on the exploratory studies of Sproles in the United States, was administered to 600 students at three girls' high schools in Choongju, Korea. Data were factor analyzed and Cronbach's alpha were computed for scale reliability. This study identified eight characteristics of consumer decision-making: (1) Novelty-Fashion conscious Consumer; (2) Perfectionistic, High Quality Conscious Consumer; (3) Recreational, Hedonistic Consumer; (4) Habitual, Brand-Loyal Consumer; (5) Brand Conscious, "Price Equals Quality" Consumer; (6) Well-Known Products Buying Consumer; (7) Price Conscious Consumer; (8) Confused by Over-Choice Consumer. Identified decision-making styles for Korean young consumers are similar to those for U.S. young consumers by Sproles. However, not all the results were equivalent. For example, 'Impulsive' factor which was confirmed characteristic for young U.S. consumers was not found in Korean data. Another example is that "Well-known Products Buying' factor confirmed in this study was not found in U.S. data. In conclusion, although the results for the Korean sample were not entirely equivalent to the U.S. sample of Sproles, similarities outweigh the differences.

본 연구의 목적은 카나다 불어권 지역, 즉 퀘벡의 문화에 대한 포괄적이고 기초적인 지식을 확립하는 데 있다. 퀘벡은 주변 영어문화권으로부터 받는 끊임없는 동화의 위협에도 불구하고 자신들 고유의 불어권 문화를 형성, 발전시킴으로써 세계 문화 구도 속에서 독특한 위치를 차지하고 있으며, 퀘벡의 역사는 문화적, 사회적, 정치적 변화 속에서 자신들만의 독특한 정체성을 형성하기 위한 퀘벡인들의 노력이 어떠한 것이었던가를 잘 보여준다. 따라서 본 연구는 카나다 불어권을 역사, 정치, 경제, 예술, 언어의 다섯 분야로 나누어 탐구함으로써 이 지역이 갖는 특수성을 보다 잘 이애하고자 하였다. 특히 다음의 사항이 주된 연구 대상이 되었다. 주요 연구대상은 카나다 불어의 역사, 문화 생활에 불어의 사용이 끼친 영향, 이중언어주의, 현재의 퀘벡의 경제상항, 다원문화주의, 문화의식과 정치의식과의 상관성, 카나다의 미래 등이었다. 이러한 연구들 통해 우리는 퀘벡이 다른 문화권들과의 관계 속에서 자신의 독자성을 잃지 않으려는 끊임없는 노력을 보여주는 동시에 '다양성 속의 통일성'이라는 자신의 궁극적 목표에 다가서려는 노력도 잃지 않는 독자적인 문화권임을 알 수 있었다. Le but de cette etude est d'etablir les connaissances preliminaires et globales sur la culture du Quebec, region francophone du Canada. Cette region a un statut particulier dans la culture mondiale; comme un petit ilot francophone entoure d'une mer anglophone, le Quebec a toujours eu la volonte de sauvegarder son identite specifique, a travers les aleas d'une histoire agitee, parfois perilleuse meme. Portant notre attension sur cette specificite, nous avons essaye d'examiner la francophonie canadienne en cinq domaines : celui de l'histoire, de la politique, de l'economie, de l'art et de la langue. Notre reflexion s'est penchee surtout sur les questions suivantes: - l'evolution du francaise au Canada a travers les siecles - l'impact de l'usage du francais sur la vie culturelle - la situation actuelle du bilinguisme canadien - la conscience identitaire des francophones canadiens - la situation actuelle economique du Quebec - Le pluriculturalisme et le modele canadien par rapport au modele americain - leur resonnance dans la conscience cuturelle et politique - l'impasse constitutionnelle et la conscience politique des Canadiens - le Canada, quel avenir? Ce faisant, nous avons pu constater que le Quebec est une region culturelle independante s'efforcant a maintenir son identite specifique dans les relations complexes avec les autre communautes culturelles et a atteindre son but essentiel : "la diversite dans l'unit".
