The purpose of this study is to suggest planning strategy of tenant mix for UEC based on the final result of tenant mix analysis of five different research cases. The following is the comprehensive explanation about the result of tenant mix planning strategy for UEC currently in operation and when planning a new facility. First, overall research cases in this study show the tendency of following an old tradition, which stresses direct sales focusing on retail and dining adaptation. In order to compensate the defect, it is suggested to adopt new type of tenants with the functional mix of retail and dining with entertainment rather than decreasing the proportion of retail and dining tenant and increasing it of entertainment tenant. Second, the floorplan of UEC should adopt racetrack or circuit form that can stimulate shoppers' circular movement so to expose them to as much tenants as possible. Service consumption mode related tenants are required to place on the side or the edge of UEC, while retail consumption mode related tenants should be planned in the center. Among dining consumption mode related tenants, impulse dining tenants like a coffee shop should be placed at the turning point or at the end of the pathway, destination tenants like a restaurant and a food court, on the other hand, is needed to be placed in the center of the space. In case of Entertainment related tenants, destination tenants like bookstore or multiplex should also be placed at the end of the pathway, and on the way to those tenants, it is required to place general tenants that can share target customers with them. On the contrary, game center or record shop like tenants that can stimulate impulse sales should be placed on the visitor's main move or near the other destination tenants. Third, anchor tenants play an important role in gathering people to the UEC, and then induce them to visit the other tenants that are located near the anchors. Thus it is suggested to plan to place general tenants on the same floor as anchor tenants are placed so they can share the characteristics of target customers which create synergy effect.

As individual family has fewer children, market sectors targeting children's goods upgrade their products quality and price. Children's wear used to be for casual activity or going to school. Recently, occasions in which children are dressed up are getting increase, such as wedding, concert or family gathering. Therefore, the industry sector of formal wears for school boys are growing. The purpose of this study is to research and grading of formal wears for school boys to improve their fit and comfort. The selected items as formal wear were tailored jacket, tuxedo, tail coat and pants. Based on the grading increments of the industry, grading was done far 7 years and 11 years old school boy for each item. Like the pattern alteration, grading increments were tested and altered through wearing tests. The final increments were suggested as the 'researched grading increments'. The results and conclusions are: 1. Appropriate size allowance, ease amount and lengths for boys are different from those far adults. The difference should be applied for boy's wear. 2. Grading increments for an age group are different from other age group. For example increments of 7 from 9 are different from that of 11 from 9. It is because a certain part grows faster during a certain age whereas other part grows faster during different period. Therefore grading for children should reflect their growth rather than same size increments which is common in adult size chart.

The purpose of this study was to comparatively analyze the kinematic variables between the squash backhand and racquetball backhand strokes through three-dimensional cinematography. Three expert racquetball players and three expert squash players were involved in the data gathering process. The horizontal, vertical and lateral displacement of racket and trunk segment, intersegmental angular velocity of the wrist, elbow and shoulder joints, and the linear velocity of the racket were descriptively analyzed, and the followings were concluded. The racket of the squash backhand stroke showed an 'U' shaped movement where the racket moved rapidly downward and moved forward to make an impact and followed through to a front-top finish, while the racket of racquetball backhand stroke showed an 'O' shaped movement where the racket showed circular movement through the rear and bottom positions for the impact, and showed rotation through the lower-front and upper front to a upper-rear-ward finish during the follow-through. The peak velocity of racket was found before the impact point in the squash backhand stroke and at the impact point in the racquetball backhand stroke. For the final conclusion, for the squash backhand stoke, instructors might be better to make the racket move downward to make highest velocity before the impact and finished short follow-through, while for the racquetball backhand stroke, to make the racket move forward to make highest velocity at the impact and finished rather long follow-through.

In the port of Ulsan with the area of harbor limit of $83km^2$, 25,432 vessels have been entering annually and only 35 vessels can anchor simultaneously at the anchorage. The area of harbor limit of Ulsan constitutes just 65 percent compared to $127.5km^2$ which is an average of main ports in Korea. In this regard, the port of Ulsan needs to expand the area of anchorages inevitably for enhancing the efficiency of port operation. To select the best anchorage area in Mipo harbor with the introduction of a concept of emergency anchorage, this study analyzed the safety of navigation and anchorage, and safety management, etc. in the prospected anchorage on the basis of the marine traffic survey observing traffic density. Furthermore, after drawing preliminary and final schemes through gathering the opinions from maritime users, safety management organizations and academic experts group, the best arrangement of emergency anchorage has been selected through the conference of interested parties. Then, the final scheme was also verified through figuring out the marine traffic system and carrying out the ship handling simulation.

Objectives : The oral health education for interaction between snack and oral health is made more in detail, it seems to contribute to improvement of oral health by reducing occurrence of dental caries. Methods : This study performed the survey for 530 high school and college students living in Y City, Chungbuk for 10 days from June 14, 2011 to understand the difference by the level of snack recognition. 530 copies of questionnaire were collected, the final 502 copies were analyzed and the results are as followings. Results : 1. As for the snack intake frequency, 'sometimes' and '2~3 times a day' was found to be largest with 32.0% respectively in female and 'sometimes' was largest with 34.9% in male. As for the '2~3 times a day' was most in high school students with 31.5% and 'sometimes' was most in college students with 39.0%. 2. As for snack characteristics, 'crispy' was most preferred in female and male with 43.7% and 39.4% respectively and, by school year, high school students and college students preferred 'crispy' most with 39.1% and 46.0% respectively. 3. As for the item of meal, 'sometimes skip' was most in female with 46.1% and 'all three meals a day' was most im male with 51.4%. 'All three meals a day' was proved to be most with 48.3%in high school students and 'sometime skip' was most in college students with 48.0%. 4. As for the difference of oral health management by school year, college students ($3.37{\pm}0.70$) proved to be higher in the oral health management (p<.01) than high school students ($2.98{\pm}0.81$) and the Negative snack recognition group ($3.24{\pm}0.73$) was found to be higher in the oral health management (p<.01) than the Positive snack recognition group ($3.06{\pm}0.82$). Although the interaction between school year and snack recognition level was not different in case of college students, the Negative snack recognition($3.17{\pm}0.77$) proved to manage higher oral health (p<.05) than the high snack recognition gathering ($2.81{\pm}0.80$) in case of high school students. 5. As for the difference of the oral health most im male wex and). Although the innteractifemale ($3.39{\pm}0.72$) proved to most the oral health (2.(p<.01) than male ($2.81{\pm}0.75$) and the group with Negative snack recognition terac ($3.24{\pm}0.73$) most d the oral health (2.(p<.01) than the group with Positive snack recognition level ($3.06{\pm}0.82$). As for effects of interaction between sex and snack recognition level, while there was not much difference in the oral health management by the snack recognition level in case of female, the cluster of low snack recognition level ($3.03{\pm}0.69$) proved to manage the oral health more (p<.01) than the gathering of high snack recognition level ($2.59{\pm}0.75$). Conclusions : To see the results as above, it can be seen the oral health management is higher as the snack recognition level is higher by sex and school year.

In this essay, following final conclusions have been drawn by analyzing medical ideology and research system of Yi cheon in Yi hak yip mun("醫學入門"). Firstly, even though the existing medical history researchers are not noting the system of Yi-cheon's medical ideology, this essay has proved the man as a doctor who succeeded the (main system) based on the content of Yi-hak-yip-mun("醫學入門") by Ju-Dan-Gae(朱丹溪). The outline of this proof is as follows. 1. Those doctors who had actively researched in Myung era(明代), were basically taking over the medical studies and result of Gum-Won era(金元代). However, depending on whose theory is to be followed, the followers are largely divided into two groups of Ju-Dan-Gae Academics(丹溪學派) and On-Boe Academics(溫補學派). In addition, both Ju-Dan-Gae Academics(丹溪學派) and On-Boe Academics(溫補學派) hold contradictory ideologies to that of the main medical system. In Yi-hak-yip-mun("醫學入門"), Yi-cheon(李?) ties The Text of Whang-Jae-Nae-Kyung("黃帝內經"), Jang-Jung-Kyung(張仲景), Yu-Ha-Gun(劉河間), Yi-Dong-Won(李東垣), Ju-Dan-Gae(朱丹溪) into one pedigree. With regard to the main system, he especially marks Ju-Dan-Gae(朱丹溪) for his efforts in gathering various medical theories into a large compilement. 2. When Yi-Cheon(李?) was writing Yi-Hak-Yip-Mun("醫學入門"), he made references to various medical publishings, among those book which he had utilized, books by Ju-Dan-Gae Academics(丹溪學派) had affected him more than anything else in terms of both quality and quantity. 3. Yi-Cheon(李?)'s "Congested Phlegm Theory(痰鬱論)" had succeeded "Congested Phlegm Theory(痰鬱論) of Ju-Dan-Gae Academics(丹溪學派). His Yi-Hak-Yip-Mun("醫學入門"), carries a more complete form of "Congested Phlegm Theroy(痰鬱論) which was made into a more systemic and widely applicable method which was by Ju-Dan-Gae Academics(丹溪學派). Secondly, Yi-Hak-Yip-Mun("醫學入門"), is a medical book which was written in the process of systemic reorganization of medical theories of various academic parties in Myung 명 era. Since this process was hearing its completion in the period of Yi-Cheon(李?), he chose specific ways of reshuffling, whilst seeking ways to efficiently utilizing existing medical information . He provided a standard to specific ways. He rearranged the existing medical theories based upon these standards. He also contributed to clinical medicine by providing description of symptoms focused upon the symptoms differentiated In Conclusion, Yi-Hak-Yip-Mun("醫學入門") holds systematic medical information which was developed by Ju-Dan-Gae Academics(丹溪學派). Also, Yi-Cheon(李?) uniformly classified the clinical experiences of existing Ju-Dan-Gae Academics(丹溪學派). He had contributed in the clinical use of Ju-Dan-Gae Academic(丹溪學派)'s clinical experience by providing main points from differentiation of symptoms.

Innovative new products and services are being launched through the convergence between heterogeneous industries, and social interest and investment in convergence industries such as AI, big data-based future cars, and robots are continuously increasing. However, in the process of commercialization of convergence new products and services, there are many cases where they do not conform to the existing regulatory and legal system, which causes many difficulties in companies launching their products and services into the market. In response to these industrial changes, the current government is promoting the improvement of existing regulatory mechanisms applied to the relevant industry along with the expansion of investment in new industries. This study, in these convergence industry trends, aimed to analysis the existing regulatory system that is an obstacle to market entry of innovative new products and services in order to preemptively predict regulatory issues that will arise in emerging industries. In addition, it was intended to establish a regulatory impact analysis system to evaluate adequacy and prepare improvement measures. The flow of this study is divided into three parts. In the first part, previous studies on regulatory impact analysis and evaluation systems are investigated. This was used as basic data for the development direction of the regulatory impact framework, indicators and items. In the second regulatory impact analysis framework development part, indicators and items are developed based on the previously investigated data, and these are applied to each stage of the framework. In the last part, a case study was presented to solve the regulatory issues faced by actual companies by applying the developed regulatory impact analysis framework. The case study included the autonomous/electric vehicle industry and the Internet of Things (IoT) industry, because it is one of the emerging industries that the Korean government is most interested in recently, and is judged to be most relevant to the realization of an intelligent information society. Specifically, the regulatory impact analysis framework proposed in this study consists of a total of five steps. The first step is to identify the industrial size of the target products and services, related policies, and regulatory issues. In the second stage, regulatory issues are discovered through review of regulatory improvement items for each stage of commercialization (planning, production, commercialization). In the next step, factors related to regulatory compliance costs are derived and costs incurred for existing regulatory compliance are calculated. In the fourth stage, an alternative is prepared by gathering opinions of the relevant industry and experts in the field, and the necessity, validity, and adequacy of the alternative are reviewed. Finally, in the final stage, the adopted alternatives are formulated so that they can be applied to the legislation, and the alternatives are reviewed by legal experts. The implications of this study are summarized as follows. From a theoretical point of view, it is meaningful in that it clearly presents a series of procedures for regulatory impact analysis as a framework. Although previous studies mainly discussed the importance and necessity of regulatory impact analysis, this study presented a systematic framework in consideration of the various factors required for regulatory impact analysis suggested by prior studies. From a practical point of view, this study has significance in that it was applied to actual regulatory issues based on the regulatory impact analysis framework proposed above. The results of this study show that proposals related to regulatory issues were submitted to government departments and finally the current law was revised, suggesting that the framework proposed in this study can be an effective way to resolve regulatory issues. It is expected that the regulatory impact analysis framework proposed in this study will be a meaningful guideline for technology policy researchers and policy makers in the future.

Since the functional importance of marine phytoplankton was firstly advocated from early 1880s massive data on the species composition and abundance were produced by classical microscopic observation and the advanced auto-imaging technologies. Recently, pigment composition resulted from direct chemical analysis of phytoplankton samples or indirect remote sensing could be used for the group-specific quantification, which leads us to more diversified data production methods and for more improved spatiotemporal accessibilities to the target data-gathering points. In quite a few cases of many long-term marine ecosystem monitoring programs the phytoplankton species composition and abundance was included as a basic monitoring item. The phytoplankton data could be utilized as a crucial evidence for the long-term change in phytoplankton community structure and ecological functioning at the monitoring stations. Usability of the phytoplankton data sometimes is restricted by the differences in data producers throughout the whole monitoring period. Methods for sample treatments, analyses, and species identification of the phytoplankton species could be inconsistent among the different data producers and the monitoring years. In-depth study to determine the precise quantitative values of the phytoplankton species composition and abundance might be begun by Victor Hensen in late 1880s. International discussion on the quality assurance of the marine phytoplankton data began in 1969 by the SCOR Working Group 33 of ICSU. Final report of the Working group in 1974 (UNESCO Technical Papers in Marine Science 18) was later revised and published as the UNESCO Monographs on oceanographic methodology 6. The BEQUALM project, the former body of IPI (International Phytoplankton Intercomparison) for marine phytoplankton data QA/QC under ISO standard, was initiated in late 1990. The IPI is promoting international collaboration for all the participating countries to apply the QA/QC standard established from the 20 years long experience and practices. In Korea, however, such a QA/QC standard for marine phytoplankton species composition and abundance data is not well established by law, whereas that for marine chemical data from measurements and analysis has been already set up and managed. The first priority might be to establish a QA/QC standard system for species composition and abundance data of marine phytoplankton, then to be extended to other functional groups at the higher consumer level of marine food webs.

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.
