3~5μm 파장대의 중적외선 영상은 화산 활동이나 산불과 같이 고온 현상을 관측하는데 효과적이다. 그러나 중적외선 영역은 지표의 복사율과 대기의 영향으로 인한 변화가 매우 심하고, 특히 낮 영상의 경우 태양 복사량에 의한 영향도 고려해야 하는 어려움이 있다. 따라서 단일밴드인 중적외선 영상을 이용하여 표면온도를 얻기 위해서는 영상이 취득된 시간과 장소에서 관측된 태양 복사량 및 여러 가지 대기 변수가 필요하다. 이 연구는 기존의 다중밴드 기반의 중적외선 영상 활용방법과 달리 단일 밴드 중적외선 영상을 이용하여 표면온도 측정을 위한 기초연구에 그 목적이 있다. 이를 위하여 MODIS 영상을 대상으로 MODTRAN을 사용하여 중적외선 영역의 대기보정 기법을 적용 한 뒤 복사전달 모델을 이용하여 지표의 온도를 측정하였다. 획득된 온도 영상의 정밀도를 측정하기 위해 기존의 온도 알고리즘인 MODIS Sea Surface Temperature 알고리즘에 의해 얻어진 해수온도와 비교를 통하여 오차 원인에 대해 분석을 실시하였다. 두 결과의 온도 차는 낮 영상의 경우 0.89±0.54℃ 밤 영상의 경우 1.25±0.41℃로 비교적 긍정적인 결과를 보였다. 그러나 낮 영상의 육지의 경우 대기에 의한 영향보다 태양빛의 반사가 주된 오차의 원인이 되며 이는 지표 복사율에 의한 영향이 매우 크게 작용하고 있음을 추정할 수 있다. 이 연구는 현재까지 해수에 대한 적용에 국한된 것으로 육상의 경우 복사율 변화가 매우 크기 때문에 중적외선 단일밴드에 의한 온도추정이 매우 어려울 것으로 예상된다. Middle-infrared (MIR) spectral region between 3.0 and 5.0 μm in wavelength is useful for observing high temperature events such as volcanic activities and forest fire. However, atmospheric effects and sun irradiance in day time has not been well studied for this MIR spectral band. The objectives of this basic study is to evaluate atmospheric effects and eventually to estimate surface temperature from a single channel MIR image, although a typical approach utilize split-window method using more than two channels. Several parameters are involved for the correction including various atmospheric data and sun-irradiance at the area of interest. To evaluate the effect of sun irradiance, MODIS MIR images acquired in day and night times were used for comparison. Atmospheric parameters were modeled by MODTRAN, and applied to a radiative transfer model for estimating the sea surface temperature. MODIS Sea Surface Temperature algorithm based upon multi-channel observation was performed in comparison with results from the radiative transfer model from a single channel. Temperature difference of the two methods was 0.89±0.54℃ and 1.25±0.41℃ from the day-time and night-time images, respectively. It is also shown that the emissivity effect has by more largely influenced on the estimated temperature than atmospheric effects. Although the test results encourage using a single channel MIR observation, it must be noted that the results were obtained from water body not from land surface. Because emissivity greatly varies on land, it is very difficult to retrieval land surface temperature from a single channel MIR data.

Basal cell carcinoma (BCC) is the most common human malignant neoplasm, accounting for 75% of all non-melanoma skin cancer. The incidence of BCC is strongly correlated with sun exposure as well as older age. Therefore, the vast majority of BCCs is observed in elderly patients on the sun-exposed skin of the head and neck with a frequency of more than 80%. BCC is very rare on sun-protected skin such as the perianal and genital regions and other etiologic factors must be considered in these cases. Although the pathogenesis of vulvar BCC is unclear, early diagnosis is very important. Because BCC in these areas sometimes seems innocuous, it is recommended that a biopsy of all suspect lesions be performed. We report a woman with BCC of the vulva treated with wide local resection and reviews the literatures on this subject.

The purpose of this study is to investigate the implications of self-regulated learning. This study investigated metacognitive, motivational, and behavioral factors of self-regulated learning through current research. In general, students can be described as self-regulated to the degree that they are meta-cognitively, motivationally, and behaviorally active participants in their own learning process. Such students personally initiate and direct their own efforts to acquire knowledge and skill rather than relying on teachers, parents, or other agents of instruction. In terms of metacognitive factors, we reviewed the importance of cognitive and metacognitive learning strategies of adolescents for better self-regulated learning. For motivational factors, recent research of self-regulated learning has tended to focus on self-efficacy and goal orientation. The current research examining behavioral factors of self-regulated learning has tended to focus on time management and academic procrastination. Research findings in the motivational aspect suggest that we need to develop the program to improve learners’ self-efficacy and recognize new re-conceptualization of the goal theory. Research findings in the behavioral aspect recommend practical tips and strategies to improve time management skills and to overcome academic procrastination. Finally, future directions for research are discussed.

The purpose of this study is to identify the nature of self-regulation on the basis of self-determination theory perspective and to investigate the methods of fostering students’ autonomously motivated behavior. According to self-determination theory, individuals have to meet three psychological needs-autonomy, competence, relatedness-to exert their competence and function well. Self-determination theory argues that motivational orientations that guide behavior have important consequences for healthy behavioral regulation and psychological well-being. Self-determination theory distinguishes between various types of motivation based on the reasons or goals that give impetus to behavior. If so, what should we do to make students learn self-determinedly based on the needs and motivations described above? First, in order to meet learners’ need for autonomy, it is important to provide them a learning environment in which autonomously motivated behavior is supported. Second, in order to enhance the learners’ competence, it is necessary to continuously provide them opportunities for learners to experience success. Finally, in order to fulfill learners’ need for relatedness, it is required to help them form more close social relationship.

The structures of catholic churches have multipurpose functions in a single one ; not alone for ritual but for congregations, educations and habitations. As a result rationally interdependent arrangement will be the keystone of styles of architecture and forms for church buildings under the control. Especially the entrance of modern catholic church buildings are for the alpha and omega of various events, -religious ceremonies, educational works, congregations and habitations, and fill the role of rooms for intermediate- space. These entrance of catholic churches reflect the architectural design of building engineers. This study in on the various purposes of the entrance in modern architecture of catholic churches, and this also shows the relation between the entrance and the rooms for special activities of each part. The derived for this study are as follows. 1. Catholic church edifices have fast increased in number since the 1980's in accordance with the expansion of religious influence, but the rate of increase has started slowing down from 1990. 2. Catholic church edifices have tendency to be constructed in a multi purpose singular structure-more than 3000㎡ high-storied massive building in a limited space thanks to having difficulty securing the sites for churches. 3. The way of using the space for religious ceremonies as the inside and outside stairway has increased since 1980. 4. The means of access to the inside by using the outside stairway show overwhelming preponderance among separate church buildings. 5. Partly-interlinking structures of churches adopt the proper methods of admission passage in conformity to their terrain and the conditions of location. Hence forward such styles of church structures can be presupposed to be the main stream in building construction.

In this intensely comteting environment that the 21c catapults us into, consumers are pivotal players in the marketing study and an indispensable consideration in communication activities. As consumption patterns are being converted from felling-oriented consumption to Pro(feeling + reasoning)-Oriented one stemming from experience of two impacts, IMF and Internet, brands should be front runner in purchase decision makings of consumers as an increasingly significant tool for consumer-related communication This research will serve as an opportunity to probe into and to research effects of brands and package designs in consumer purchase behaviour, and to try to put brand operation management and strategies development in place. rand assets are composed of brand preference, perceived quality, association, and awareness. Among these elements, association is a function to enable consumers to identify features of product and to form brand image. Association can break into perceived value, brand personality, and benefits of product. Sentence-type brands as part of a brand management strategy to maximize association effects help find out the method for consolidating the relationship between brands and consumers without excessive efforts of marketing activities required. Because the sentence-type brands that are naturally armed with more close and specific expressions on packages can act as a vehicle for prompting the understanding of the consumer about products and for more effective communicating at point of purchase. for successful operation of sentence-type brands, clear understanding of brand concepts should go first. Requirements of using sentence-type brands are, first, to identify advantages and disagvantages of the concerned brand, to differentiate amid competitors brands, to extract essential values from lifestyles of consumers, and, finally, to define them. Of course there has been an undisputed argument that package design cannot be too emphasized as an inevitable means for product differentiation and brand image formation. Thus the potential link of package design strategy to brand operation strategy that adjusts itself to dovetail individual characteristics of specific industries should be considered. In order to measure the purchase-attraction degrees of sentence-type brands, we need to identify elements of sentence-type brands and to build up research and analysis on consumer behavior responding to individual or general clues about functions and roles of the related elements represented by sentence-type brands. Unfortunately, we don't show any level of attainment with satisfactory follow-ups. We estimate this scarcity of research has been caused by the absence of reasonable and reliable measuring tools to gauge he effects in the market of sentence-type brands. This reaserch tries to provide theoretical background on how to measure effect defree of sales motivated by sentence-type brand products and to discuss about related marketing strategies and tactics. For that purpose, we examine domestic food and beverage products that have tather aggressively adopted sentence-type brands in market applicatopns. Besides, we try to illustrate a contrasting picture in Japan where we could witness more distinct applications of sentence-type brands in the market and their sales effects augmented by aggressive introduction of them on packages. Results show that domestic sentence-type brand products reveal a slut of problems to be addressed, compared with Japan's. It is concluded that domestic brand operators are short of full recognition of purchase attraction effects of sentence-type brands and have no wielding power over package design strategies that make enhanced communication effects possible. Thus we suggest that it is very important to in depth review package design problems of domestic sentence-type brand operations. Package designs whose surfaces are expressed with sentence-type brands that can arouse favorable associations leading to purchase behavior of consumers should be seriously considered. In conclusion, marketing operators should keep in mind as a brand operation strategy the potential utilization of sentence-type brands in the arena of low-involved products such as foods and beverages so that companies obtain two benefits: reduced marketing cost and promotion effect. For this sentence-type brand strategy to be successful, both brand name department which primarily consider linguistic communication and design department should go band in hand, consistently planning, spelling out, and realizing core values in the market.

The purpose of this study is to critically inquire into alternative approach in intelligence research and to suggest new perspective to the nature and development of intelligence. Virtually every history of human intelligence research places the formal beginning at the turn of the 20th century, with the work of Spearman and Binet. Their psychometric approach to identify individual differences in intelligence was clearly the first successful and the most influential one. But, in the 1960s and 1970s, many investigators became disillusioned with the psychometric approach, because psychometric model of intelligence has not been particularly successful in generating successful intervention programs for training intelligent functioning. Beginning in the mid-1960s, researchers explored a long series of topics whose organizing feature was a concern with the actual, on-line cognitive activity of the individual. This information-processing framework provided the impetus for the development of sophistigated experimental tasks and techniques to investigate various aspects of human cognition. The theoretical complementarity of psychometric and cognitive approach to human cognitive activity, in particular as represented by information processing and measurement of intelligence, was soon noted and employed. This evolutionary view was predicted a successful integration of correlationally based structural theories and experimentally bated processing theories in the future. But it is persuasive enough to argue such an integration is unlikely if not possible, because those approaches have fundamental misconceptions about the nature and development of human intelligence. Most of the misconceptions due to the missing contextual constructs such as development, meaningfulness, goals, motivation, social change, social structure, and culture. In recent, the systems theories attempt indifferent wags to integrate cognition and context. But they are unclear, because they have taken the notion of intelligence too far, and have included within their scope abilities or attributes that go beyond intelligence. Conclusionally, recognizing and refuting not only the critically unexamined core of conventional thinking about human intelligence but also the obstacles to that critical examination that stem from social structure of social science research, are major step toward improved theory and practice.
