This study proposes a device for the organizational frameworks and essential (content) elements of world realms in world regional geography subject. Here, the term 'organizational framework' means the method of realms division, reasonable number and naming of realms, and approaches to reams inclusively. And the term 'essential elements' designate the core elements as big ideas that every student must study through world reams. To approach these thesis, the author suggests that there is a growing trend of a combined regional concept to apply for reams division, that it is necessary to rationalize the number of realms and to prepare rather a synthetic approach to realms than a single one. And then, the author presents five essential elements as big ideas of world reams that composed of four by thematic approach and one by global-issue approach. But, this study emphasizes that in organizing the essential elements for a realm it is a better strategy to bring elements selectively with a realm because certain element fulfils function specially to certain realm.

Noju Oh Hui-sang was a Confucian who was active during the reign of King Sunjo in late Joseon Dynasty and he also was a master of the Sallim faction. Though he is known as an eclectic Neo-Confucian, he had profound knowledge in the study of Confucian classics as well through succeeding the family study handed down by his father Oh Jae-sun and his oldest brother Oh Yun-sang. This thesis hereby examines Noju's Confucianism doctrine and its characteristics. Noju's Confucianism doctrine is characterized significantly with the following aspects. First, its analyses are detailed overall and it annotates chapters and verses mostly related to Neo-Confucian theories on interpretation of the Confucian classics. Second, it conducts in-depth study not only on Chu Hsi's annotation but also on the small commentaries (小注) in Compendium of the Commentaries on Four Chinese Classics (四書集註大全). In terms of Chu Hsi's theory, however, Noju interprets Confucian classics while supplementing shortcomings on Chu Hsi's theory rather than opposing it. For opinions of all philosophers and scholars on small commentaries, it expresses rather critical theories than supporting ones. Third, it quotes many theories not only of Chinese Confucians but also of Korean ones. It mainly introduces theories of Namdang Han Won-jin, including those of Yi Yulgok. Among them, it particularly has frequent quotations from Han Won-jin's Kyoungyigimunrok (經義記聞錄). Fourth, Noju actively acknowledges senior Confucians' theories many times in quoting them but he also daringly points out their errors when a theory is thought not to be appropriate. He indicates errors one by one in theories not only of Uam and Yulgok but even of Mencius. Fifth, it especially discusses Book of Changes (周易) in depth. It tends to criticize Chengzi's I-Chuan (易傳) but accept Chu Hsi's Benyi (本義). It roughly explains Book of Changes in general but seldom directly accounts for trigrams of it other than Qian trigram and it has detailed explanation especially on Xicizhuan (繫辭傳).

Credit transactions are used as a means of price discrimination from competitors in order for suppliers to increase customer demand. In particular, in the case of a two-stage supply chain consisting of a supplier, a retailer, and a customer, the deferral of payment for goods allowed by the supplier is a means of reducing the inventory investment cost of the retailer. Retailers have the opportunity to discount the selling price while anticipating an increase in end-customer demand through the reduction of the inventory investment cost. In view of the fact that such trade credit is provided for the purpose of increasing demand as a means of discrimination from competitors, it may be more general that the credit transaction period is allowed flexibly according to the transaction volume. In particular, in the case of deteriorating products, the credit transaction period given according to the order volume is a factor that increases the order volume of the retailer, but product deterioration can be a limiting factor in the increase in the order volume. The deterioration rate actually plays an important role in determining the inventory policy of the retailer. Therefore, in this paper, the effect of such deterioration rate on the inventory policy of retailer is analyzed.

This study aimed to investigate the impact of scores on the Test of Proficiency in Korean (TOPIK) among foreign exchange students on academic adaptation. Recruited students, approved by the Institutional Review Board (IRB), totaled seven, and their interview contents were analyzed using a comprehensive analysis procedure based on pragmatic eclecticism (Lee, Kim, 2014), utilizing six stages. As a result, factors influencing academic adaptation of Korean language learners for academic purposes were categorized into three dimensions: academic, daily life, and psychological-emotional aspects. On the academic front, interviewees pointed out difficulties in adapting to specialized terminology and studying in their majors, as well as experiencing significant challenges with Chinese characters and Sino-Korean words. Next, from a daily life perspective, even participants holding advanced TOPIK scores faced difficulties in adapting to university life, emphasizing the necessity of practical expressions and extensive vocabulary for proper adjustment to Korean life. Lastly, within the psychological-emotional dimension, despite being advanced TOPIK holders, they were found to experience considerable stress in conversations or presentations with Koreans. Their lack of knowledge in social-cultural and everyday life culture also led to linguistic errors and contributed to psychological-emotional difficulties, despite proficiency in Korean. Based on these narratives, the conclusion was reached that in order to promote the academic adaptation of Korean language learners, it is essential to provide opportunities for Korean language learning. With this goal in mind, efforts should be directed towards enhancing learners' academic proficiency in their majors, improving Korean language fluency, and fostering interpersonal relationships within the academic community. Furthermore, the researchers suggested as a solution to implement various extracurricular activities tailored for foreign learners.

News contents has been collected, selected, edited and sometimes distorted by the news recommendation mechanisms of online portals in nowadays. Prior studies had not confirmed the consensus of newsworthiness, and they had not tried to empirically validate the impacts of newsworthiness on audience reactions. This study challenged to summarize the concepts of newsworthiness and validate the impact of representativeness of both editor's and audience's perspective on audience reactions as perceived news quality, trust on news portal, perceived usefulness, service satisfaction, loyalty, continuous usage intention, and word-of-mouth intention by adopting the representativeness heuristics method and information adoption model. 357 valid data had been collected using a scenario survey method. Subjects in each groups are exposed by 3 news recommendation mechanisms: 1) the time-priority news exposure mechanism (control group), 2) the reference-score-based news recommendation mechanism (a single treatment group), and 3) the major-news-priority exposure mechanism sorting by the reference scores made by peer audiences (the mixed treatment group). Data had been analyzed by the MANOVA and PLS method. MANOVA results indicate that only mixed method of both editor and audience recommendation mechanisms impacts on perceived news quality and trust. PLS results indicate that perceived news quality and trust could significantly affect on the perceived usefulness, service satisfaction, loyalty, continuance usage, and word-of-mouth intention. This study would contributions to empathize the role of information technology in media industry, to conceptualize the news value in the balanced views of both editors and audiences, and to empirically validate the benefits of news recommendation mechanisms in academy. For practice, the results of this study suggest that online news portals would be better to make mixed news recommendation mechanisms to attract audiences.

RFID is a technology that uses radio frequency to read information in tags attached to objects or people. Because it reads the information without contact when tracking the location using tags in a RFID system, there can be errors between the actual position and measured position. In this paper, three methods (the method of radiation pattern, the method of the median value, and the method using both the radiation pattern and median value) are proposed to identify the location of objects or people using the RFID technique. The location identification system based on RFID was constructed and tags were arranged in a square pattern. The real location and experimentally predicted location of an object containing a reader were compared to confirm the error. Instead of the existing papers that obtained the approximately location of a reader by calculating the center of gravity of all tags read by that reader, in this study, the predicted location was obtained by the median value and the radiation pattern. This study validated which method was the most efficient among the three methods proposed in this paper through the data of the read tags. As a result, the method of the median value had the smallest error among those assessed.

In many cases of orthodontic treatment the upper anterior teeth are retracted. Periodontal problems may arise during incisor retraction, if the amount of tooth movement and the amount of remodeling in the anterior cortical bone are not the same. Therefore in this study, to find out the relationship between the amount of tooth movement and the amount of bone remodeling during retraction of the upper anterior teeth, lateral cephalograms of 56 female patients over 18-year-old were taken before and after treatment. Among the 56 patients, two groups were divided according to the type of root movement during retraction. 26 patients mainly moved by tipping and 30 by bodily movement. The cephalograms taken before and after treatment were superimposed upon the true horizontal plane. In the Tip-Group, the horizontal bone remodeling/tooth movement ratio was 1:1.63, and in the Torque-Group it was 1:1.66. Because the amount of tooth movement and the amount of bone remodeling were not the same in both groups, in the Tip-Group the root apex moved away from the palatal cortical plate and closer to the labial cortical plate, whereas in the Torque-Group the root moved away from the labial cortical plate and closet to the palatal cortical plate. Therefore, there are limitations in the amount of incisor retraction in patients with a very thin anterior cortical plate in the maxilla, and in patients with severe skeletal discrepancies orthognathic surgery should be considered and when orthodontic camouflage treatment is the only possible method, the orthodontist must be aware of the limitations of treatment.

This paper mainly deals with the appropriation of ship voyage allocation, using a heuristic regression model, in order to reduce total costs incurred in port, yard and at sea under the specific port condition. Because of different behavior of costs incurred in port, yard and at sea, an effort to minimize these costs by adjusting the number of voyages for three ship classes(50,000, 100,000, and 150,000-ton) should be made. For instance, if the port managers attempt to reduce the sea transport cost by increasing the annual allocated number of ship voyages classed 150,000-ton for economies of scale, they have no choice but to suffer a significant increase in queueing cost due to port congestion. To put it differently, there are trade-off relationships among the costs incurred in port, yard, and at sea. We utilized a computer simulation result to perform a couple of regression analyses in order to figure out the appropriate range of allocated number of voyages of each ship class using a heuristic approach. The detailed analytical results will be shown at the main paper. We also suggested a net present value(NPV) model to make a proper investment decision for an additional berth of 200,000-ton class that alleviates port congestion and reduces transport cost incurred both in port and at sea.

The purpose of this study is to investigate the fashion reflecting the aesthetic consciousness of a generation and age spirit and to study Mods-Look aesthetically by analyzing how Mods-Look expressed on the fashion magazines(Collezioni Donna) from 2001 to 2006 developed into a new form. 1960's Mods-Look appeared in the well known collections such as New York, Paris, Milan in the form of crossover or with a changed style. Especially after 2000's, in addition to the British fashion, even a new word Mods Story was created to prominently express the free style of the Mods spirit. The expressive characteristics represent 1) minimal style, 2) sports casual style, 3) vintage style, 4) dandy & androgynous style. In conclusion, Mods-Look in 21st fashion used to be street fashion started from minority subculture after world war II, but now suit of that time, geometrical pattern and sensibility are becoming design sources for the various fashion market from high fashion to sports look. Therefore, as young people are becoming the center of society in new millenium, sensibility of that time will be reinterpreted to design and Mods-Look will not be limited to subculture but reflected in design development fulfilling people's taste and new future fashion sense by compromising the past and new trend.

This study is explored the relationship of cultural history between the culture of mental stroll about nature and the traditional landscape architecture spaces, which showed various aspects of developments, based on the records as to landscape architecture spaces. The philosophical view on nature was turned into the esthetic view with the mellow ripeness of multifarious cultures in Choseon period, since the life of literati had to be a comprise between the Confucius' life and the Taoist life. Around the seventeenth century, as the culture of enjoying a secluded life in city had been descended, the aspiration to appreciate nature in daily life with the changed view on nature. Those desires made the Wa-yu culture, which has a meaning of mental stroll about nature, and drew the attention and various kinds of the Wa-yu culture had bloomed. In the field of Korean literature, the record of strolling in nature had flourished, while the realistic landscape painting had emerged in the field of art. In the field of landscape architecture, the building of places where the vivid experience of nature was realized in the aspect of impressions was performed to express their utopia. Indeed, the space of traditional landscape architecture in the reality meant more than the actual nature.
