The purposes of this research are twofold; 1) to verify spatial differences of tectonic movement using the spatial distribution of earthquakes, and 2) to infer mechanisms that generate spatial accumulation patterns of earthquakes in the Korean Peninsula. The first part of this sequential paper (Park, 2007) argues that the Korean Peninsula consists of four geostructural regions in which tectonic deformation and consequent geomorphological development patterns are different from each other Since this conclusion has been made by terrain analyses alone, it is necessary to verify this suggestion using other independent geophysical data. Because earthquakes are results of movement and deformation of land masses moving in different directions, the distribution of earthquake epicenters may be used to identify the direction and rates of land mass movement. This paper first analysed the spatial distribution of earthquakes using spatial statistics, and then results were compared with the spatial arrangement of geostructural regions. The spatial distribution of earthquakes in the Korean Peninsula can be summarized as the followings; firstly, the intensity of earthquakes shows only weak spatial dependency, and shows large difference even at adjacent regions. Secondly, the epicenter distribution has a clear spatial accumulation pattern, even though the intensity of earthquake shows a random pattern. Thirdly, the high density area of earthquakes shows a clear 'L' shape, passing through Pyeongannam-do, centered at Pyeongyang, and Hwanghae-do, Seosan and Pohang. The correlation coefficient between the density of earthquakes and distance from geostructral region boundaries is much higher than those between the density of fault lines and distance from tectonic division boundaries. Since fault lines and tectonic divisions in the Korean Peninsula are the results of long-term geological development, there is an apparent scale discrepancy to find significant correlations with earthquakes. This result verifies the research hypothesis that the Korean Peninsula is divided into four geostructral regions in which each has its own moving direction and spatial deformation characteristics. The existence of geostructural regions is also supported by the movement parrerns of land masses estimated from the GPS measurements. This conclusion is expected to provide a new perspective to understand the geomorphological developments and the earthquake occurrences in the Korean Peninsula.

Most Korean Buddhist paintings from the late Joseon period were produced through collaborative projects (bulsa) between clans of Buddhist monks and monk artists (hwaseung), in which the monk clans would select themes and iconography for works that would then be produced by the artists and their school. Thus, any attempt to understand the Buddhist paintings of this period must consider not only the stylistic characteristics of the monk artists, but also the conditions at the respective temple at the time of production. Applying this methodology, this paper examines the collaboration between the Buhyu monk clan and the monk artist Uigyeom and his fellow artists (hereinafter, the "Uigyeom School") that took place in Honam (湖南) and surrounding areas in the eighteenth century. In particular, the paper reveals the strong influence that the Buhyu clan exerted on paintings that the Uigyeom School produced in 1724 and 1725 at Songgwangsa Temple, the clan's main temple. Following the paintings for Songgwangsa Temple, the Uigyeom School actively participated in similar projects at regional temples under the auspices of the Buhyu clan in Honam, Hoseo (湖西), and Yeongnam (嶺南). Consequently, the Buhyu clan granted Uigyeom several honorable titles-including "Hoseon" (毫仙), "Jonsuk" (尊宿), and "Daejeonggyeong" (大正經)-that were rarely conferred to a monk artist. Such acclaim helped Uigyeom's style of Buddhist painting to become widespread throughout the three southern provinces of Korea. The paintings for Songgwangsa Temple exemplify how the Buhyu clan and Uigyeom School collaborated to visualize the thoughts and philosophies of the Buhyu clan. For the Uigyeom School, this project served as the foundation for building the reputation and esteem of Uigyeom, who became one of the most esteemed and influential monk artists of the late Joseon period. As such, the paintings created for Songgwangsa Temple in 1724 and 1725 have great significance not only for Korean Buddhism, but also for art history in general.

The purpose of this paper is to analyse the locations and to interpret the landscapes of the local towns in Joseon Dynasty from Feng-shui's point of view. As a result of analysing the locations of towns in Gyeongsang Province, the towns which have typical Feng-shui landscapes make up to 58% of the total. Historically, the local towns that were established in the early period of the Joseon Dynasty didn't reveal Feng-shui's landscape, but those that were established in the late period of the Joseon Dynasty revealed the Feng-shui's landscape clearly. In this article, I classify the local towns of the Gyeongsang Province into 3 types: 1. Non Feng-shui type These towns are located near the seashore. The main reason that these towns were located at the seashore was defense against an enemy. 2. Semi Feng-shui type. These towns don't have natural location but have a man-made landscape, based on the principles of Feng-shui. 3. Typical Feng-shui type. These towns were typically administrational towns which were located at the center of a local region.

Concerning the differences in the tales between the Investigation of Historical Remains of Patriarch Jinmuk (hereafter, IHRPJ), as well as those which appear in Jeungsanist Thought and Daesoon Thought, previous studies view such differences as Jeungsan's intentional modification of the original intent of the narratives or as indicating differences in beliefs and values. This style of interpretation seeks to reconcile both Korean Buddhism and Jeungsanist and Daesoon Thought based on the premise that the former and the latter two exhibit differences in values. This study accepts the above view of the differences in description according to values. However, the differences between the tales of Jinmuk that appears in IHRPJ versus those in The Canonical Scripture can be approached from a new perspective, i.e., the differences that exist between literary and oral traditions; rather than only stemming from potential differences in the world views espoused by Buddhism and Daesoon Thought. These refer to the IHRPJ, which was constructed first as literary narratives in the 19th century; however, there was also folklore that had been handed down from the 18th century. As a result of examining the relationship between Jinmuk and Bonggok via this interpretive horizon, the contents of the IHRPJ are found to reflect the values and intentions of the intellectual class, such those held by Master Cho-ui and Kim Ki-jong, whereas oral traditions can be seen as a reflection of the hopes of the people of the late Joseon Dynasty. Jeungsan should also be interpreted as having utilized folklore in his teachings. Meanwhile, the circumstances and intentions behind publishing the IHRPJ are analyzed in the context of the text's historical background and the relationship between Confucianism and Buddhism during the 16th through 19th centuries. In particular, through the Compilations of Wandang and the collection of writings of Buddhist monastics, I have evaluated that Confucianism needed to purify and correct materials according to the ideology of the times in order to promote a spirit of morality and courtesy. Likewise, Buddhist Master Cho-Ui also embellished records to benefit Buddhism and deleted oral records that could harm the reputation of Buddhism. On the other hand, when viewing Records of Shrine Renovation and existing oral traditions, it can be shown that some Jinmuk tales existed in the 18 th century which were not included in the IHRPJ. Thereby, Jeungsan's description of Jinmuk tales can be reappraised as accepting the oral secular tradition that conveyed the wishes of the people. In other words, compared to the IHRPJ, which reflects only the harmonious content of Confucianism and Buddhism due to political and social factors, The Canonical Scripture reflects oral traditions that were widespread during the late Joseon Dynasty. As evidence, it can be suggested that there are many narratives about the relationship between Jinmuk and Bonggok that center on Bonggok's jealousy and the murder of Jinmuk. Jeungsan aimed to encompass people of all classes according to their minds and wills rather than their political positions or statuses. Therefore, Jeungsan did not need to rewrite the narrative content that had been passed down via oral tradition. Instead he embraced those narratives as a projection of the voices of the people.

After emergence of Internet, social media with highly interactive Web 2.0 applications has provided very user friendly means for consumers and companies to communicate with each other. Users have routinely published contents involving their opinions and interests in social media such as blogs, forums, chatting rooms, and discussion boards, and the contents are released real-time in the Internet. For that reason, many researchers and marketers regard social media contents as the source of information for business analytics to develop business insights, and many studies have reported results on mining business intelligence from Social media content. In particular, opinion mining and sentiment analysis, as a technique to extract, classify, understand, and assess the opinions implicit in text contents, are frequently applied into social media content analysis because it emphasizes determining sentiment polarity and extracting authors' opinions. A number of frameworks, methods, techniques and tools have been presented by these researchers. However, we have found some weaknesses from their methods which are often technically complicated and are not sufficiently user-friendly for helping business decisions and planning. In this study, we attempted to formulate a more comprehensive and practical approach to conduct opinion mining with visual deliverables. First, we described the entire cycle of practical opinion mining using Social media content from the initial data gathering stage to the final presentation session. Our proposed approach to opinion mining consists of four phases: collecting, qualifying, analyzing, and visualizing. In the first phase, analysts have to choose target social media. Each target media requires different ways for analysts to gain access. There are open-API, searching tools, DB2DB interface, purchasing contents, and so son. Second phase is pre-processing to generate useful materials for meaningful analysis. If we do not remove garbage data, results of social media analysis will not provide meaningful and useful business insights. To clean social media data, natural language processing techniques should be applied. The next step is the opinion mining phase where the cleansed social media content set is to be analyzed. The qualified data set includes not only user-generated contents but also content identification information such as creation date, author name, user id, content id, hit counts, review or reply, favorite, etc. Depending on the purpose of the analysis, researchers or data analysts can select a suitable mining tool. Topic extraction and buzz analysis are usually related to market trends analysis, while sentiment analysis is utilized to conduct reputation analysis. There are also various applications, such as stock prediction, product recommendation, sales forecasting, and so on. The last phase is visualization and presentation of analysis results. The major focus and purpose of this phase are to explain results of analysis and help users to comprehend its meaning. Therefore, to the extent possible, deliverables from this phase should be made simple, clear and easy to understand, rather than complex and flashy. To illustrate our approach, we conducted a case study on a leading Korean instant noodle company. We targeted the leading company, NS Food, with 66.5% of market share; the firm has kept No. 1 position in the Korean "Ramen" business for several decades. We collected a total of 11,869 pieces of contents including blogs, forum contents and news articles. After collecting social media content data, we generated instant noodle business specific language resources for data manipulation and analysis using natural language processing. In addition, we tried to classify contents in more detail categories such as marketing features, environment, reputation, etc. In those phase, we used free ware software programs such as TM, KoNLP, ggplot2 and plyr packages in R project. As the result, we presented several useful visualization outputs like domain specific lexicons, volume and sentiment graphs, topic word cloud, heat maps, valence tree map, and other visualized images to provide vivid, full-colored examples using open library software packages of the R project. Business actors can quickly detect areas by a swift glance that are weak, strong, positive, negative, quiet or loud. Heat map is able to explain movement of sentiment or volume in categories and time matrix which shows density of color on time periods. Valence tree map, one of the most comprehensive and holistic visualization models, should be very helpful for analysts and decision makers to quickly understand the "big picture" business situation with a hierarchical structure since tree-map can present buzz volume and sentiment with a visualized result in a certain period. This case study offers real-world business insights from market sensing which would demonstrate to practical-minded business users how they can use these types of results for timely decision making in response to on-going changes in the market. We believe our approach can provide practical and reliable guide to opinion mining with visualized results that are immediately useful, not just in food industry but in other industries as well.

This study is to reclassify the classifications or definitions of scientific literacy in scientific literacy researches since 1960s and grasp the classification trends of scientific literacy definitions. Sixteen articles have been selected among the articles that have been introduced in the two articles. Classification criteria are as follows: 1) "be learned," "competence," or "be able to function in society" as meanings of "literate," 2) "terms" or "description" as the ways of representing scientific literacy, 3) "singular structure," "hierarchical structure," or "parallel structure" as the inner structure of scientific literacy definitions. The results of this study are as follows: First, hierarchical structures in scientific literacy have almost always accompanied "terms" representing scientific literacy and also accepted the hierarchy between "be learned" and "competence," but not the definition of scientific literacy as functioning in society. All parallel structures in scientific literacy have accompanied the definition as functioning in society. And singular structure almost always appears in researches based on the views of scientific literacy in relatively recent times. Second, researches who have used "terms" as ways of representing scientific literacy have increased. Based on the results in this study, the meanings of scientific literacy have been emphasized in view of the ability of playing a role in a social context as well as learning and competence these days. To meet this movement in scientific literacy actively, science education community should get out of traditional teaching and learning scientific concepts and give emphasis on application in various context and social role of science learners.

From the four tuna purse seiners operating in the western equatorial Pacific waters 370 tuna schools were sampled on attribute of the school, fishing operation of purse seine sit and catch. The data were tabulated and subjected to the statistical tests of independency on the associated object and availability of the school, and catch per set of purse seine fishery as well. The resultant inferences are as follows. 1. Most frequent attributes of the tuna schools found on the surface are associated with sea birds, bait fishes and the flotsams. 2. In fishing operations of purse seine sets on the flotsam-associated schools, the settings were more frequently performed at dawn than in day-time. In fishing operations on the sea-birds-associated schools, the siftings were more frequent in day-time than at dawn. 3. From the flotsam-associated schools the successful sets were significantly more frequent. 4. In the fishing operations of purse seine sets, some of the flotsam-associated schools were subjected to the supplementary sets in success to the initial sets until the schools were consummated. 5. The fish-attracting effect of the flotsam is correlated with structure of the flotsam, but not with length of the flotsam. The flotsams, which tend to attract large tuna schools are the complicated-structure flotsams, i, e. driftwoods with roots or branches or with both of them, otherwise a bunch of uprooted bamboo shrubs, while a log without roots and branches tend to be an attractant inferior to the flotsam of complicated structure.

Learning styles are the methods of gathering, processing, interpreting, organizing the information. VARK learnig inventory is instructional preference classified according to their visual(V), aural(A), read-write(R), and/or kinesthetic(K) sensory modality preferences(SMP). Learner-centered learning is emphasized, but there are few studies on VARK learning styles in Korean medical school. The purposes of this study were to assess the student' SMPs and compare those with gender, status, and academic achievement. The subjects of study were 394 students at C Medical School and Graduate School of Medicine. For the study style test, 16 questions were used in Korean version of VARK test paper© 7.0 developed by Fleming provided on the VARK website. Academic achievement was converted into a standardized score(t score). Frequency analysis, cross analysis, and variance analysis(t-test, ANOVA) were conducted to identify learning style disposition and differences between groups. The uni-modal type was 87(22.1%) and the multimodal was 307(77.9%). Regardless of gender, quasi-modal VARK was the most preferred. There was no significant difference in learning styles by gender. The first grade in medicine was the lowest in uni-modal type(8.8%) and the highest in quasi-modal VARK type(47.8%), while the fourth grade was the highest in uni-modal type(30.7%) and the lowest in quasi-modal VARK type(19.8%) and tri-modal type(19.8%). There was no difference in academic achievement by all learning types(F=1.09, p=0.37). The knowledge about students' learning styles is helpful for instructors to apply more learner-centered teaching strategies in medical education.

Purpose: This study was conducted to explore the professional identity of elementary school health teachers. Methods: In-depth interviews with fifteen elementary school health teachers were conducted from July 2010 to August 2012. Qualitative data collected by the researcher including transcription and field notes were analyzed through an adapted methodology based on the Grounded Theory of Strauss and Corbin. Results: Fifteen categories, 35 sub-categories and 120 concepts were obtained. The key category that was consistently maintained in identity formation was 'keeping themselves being a teacher providing nursing' which has three styles, 'focusing on health education', 'combining nursing and education' and 'focusing on providing nursing care'. Conclusion: Results of this study will provide basic information for preparing manuals regarding the range of activities in school health teachers' jobs, improving promotion and merit payment systems for school health teachers, creating support programs for them, and contributing to the formation and establishment of their professional identity.
