Over the past few years, as maritime trade and traffic were highly expanding, problem of invasive species via ballast water have been raised. In 1988, Canada and Australia had firstly experience that unexpected and hazardous species were observed on their own sea, they have issued the problem to MEPC under the IMO. At the end of many years of discussion, on the diplomatic conference in 13 Feb. 2004, "International Convention for the Control and Management of Ballast Water and Sediments of the Ship" was adopted. Requirements for entering into force of this Convention is that 30 countries ratify and world merchant marine fleet is more than 35% and BWM Convention will be effected after 12months from date satisfying conditions. With Finland ratifying the BWM Convention on 8 Sep. 2016, the fleet amounted to 35.1441% and ratification country became 52 countries. Therefore, after 12month, BWM Convention will be formally effected on 8 Sep. 2017. Ballast Water Treatment System is to be fitted in new ships as well as existing ships. Thus, there are concerns of ship owners to be suitably installed a variety typed BWTS in many kinds of vessels. As approaching for resolving these problems, engineering analysis was carried out research studies and detailed design to analyze to optimal installation space for retrofitting a BWTS using 3D Scanning method, targeting representative DWT 180K Bulk carrier of dry cargo vessels charged more 40% on worldwide vessel and mainly two type BWTS as electrolysis treatment type and ultra violet treatment type. Optimal design of 3D Scanning technology was applied to analyze four step process and the overall conclusion was described in this paper.

Users of World Wide Web (Web) experience difficulties in the retrieval of pertinent information due to the increased information provided by Web sites and the complex structure of Web documents that are continuously created, deleted, restructured, and updated. Web providers' efforts to maintain their sites are tend to be less than that of site creation due to the expenses required for maintenance. If information of relationship among Web documents and their validity is provided to Web managers as well as Web developers, they can better serve users. In order to grasp the whole structure of a Web site and to verify the validity of hyperlinks, traversal and analysis of hyperlinks in a Web document are required to provide information for effective and efficient creation and maintenance of the Web. In this paper, we introduce a Web Editor specialized for Web maintenance. We emphasized on two aspects: first, the analysis of HTML Tags to extract hyperlink information and second, establishment of the relationship among hyperlinked documents, and verification of the validity of them.

Background: Lung cancer is the most lethal type of cancer in the world. Several benign lung diseases may mimic lung carcinoma in its clinical and radiological presentation, which makes the differential diagnosis for granulomatous diseases more relevant in endemic regions like Brazil. This study was designed to describe the prevalence and the diagnostic work-up of benign diseases that mimic primary lung cancer in patients hospitalized at a university hospital from south of Brazil. Methods: This was a transversal study, which evaluated the medical records of 1,056 patients hospitalized for lung cancer treatment from September 2003 to September 2013 at University Hospital of Santa Maria. Results: Eight hundred and four patients underwent invasive procedures for suspected primary lung carcinoma. Primary lung cancer was confirmed in 77.4% of the patients. Benign disease was confirmed in 8% of all patients. Tuberculosis (n=14) and paracoccidioidomycosis (n=9) were the most frequent infectious diseases. The diagnosis of benign diseases was obtained by flexible bronchoscopy in 55.6% of the cases and by thoracotomy in 33.4%. Conclusion: Infectious diseases are the most frequent benign diseases mimicking lung cancer at their initial presentation. Many of these cases could be diagnosed by minimally invasive procedures such as flexible bronchoscopy. Benign diseases should be included in the differential diagnosis during the investigation for primary lung cancer in order to avoid higher cost procedures and mortality.

Quality control of Argo(Array for Real-time Geostrophic Oceanography) data is crucial by reason that salinity measurements are liable to experience some drift and offset due to biofouling, contamination of sensor and wash-out of biocide. The automated Argo real-time quality control has a limit of sorting data quality, so that WJO program is adopted as standardized method of Argo delayed mode quality control (DMQc) in the world that is a precise quality control method. We conducted DMQC on pressure, temperature and salinity measured by Argo floats in the Pacific Ocean including expert evaluation. Particularly, salinity data were corrected using WJO program. 4 salinity profiles of Argo delayed mode were compared with nearby in situ CTD data and other Argo data in deep layer where oceanographic conditions are stable in time and space. The differences of both salinities were lower than target accuracy of Argo. As compared with the difference of salinities before DMQC, those after DMQC decreased by 60-80 percent. Quality of delayed mode salinity data seemed to be improved correcting salinity data suggested by WJO program.

In rehabilitation where ultrasonographic diagnosis is not popular, it could be subjective by medical expert's experience. Thus, it is necessary to develop an objective automative procedure in ultrasonic image analysis. A disadvantage of existing automative analytic procedure in musculoskeletal system is to designate an incorrect muscle area when the figure of fascia is vague. In this study, we propose a new procedure to extract more accurate muscle area in abdomen ultrasonic image for that purpose. After removing unnecessary noise from input image, we apply End-in Search algorithm to enhance the contrast between fascia and muscle area. Then after extracting initial muscle area by Up-Down search, we trace the fascia area with a mask based on morphological and directional information. By this tracing of mask movements, we can emphasize the fascia area to extract more accurate muscle area in result. This new procedure is proven to be more effective than existing methods in experiment using convex ultrasound images that are used in real world rehabilitation diagnosis.

The aging of the population has been in process all over the world including most of advanced countries. With the improvement of living standards and medical technology due to the growth and development of the modern industrial society, the continuous Increase of the average lifespan has led to an abrupt growth in the population ratio of the aged. The senescence is the period where both physical and mental functions get dwindled, and due to a loss of roles in a society and a weakened social bond, the elderly people feel often neglected and isolated. Consequently, the elderly people spend a lot of time in their houses. As this means that the elderly gets higher possibility to stay within housing units and housing complex environment, residents' public space needs to be developed within the housing complex for them. Therefore, constructive programs and plans are required for the elderly who experience distance constraint because of corporal aging, for them to sustain community activities within their housing environment. Contrary to them in the 20th century, the elderly living in the nowadays informational society tend to enjoy their leisure times with arts and cultures and underscore the significance of social exchange under diverse possibility and sustainableness. Thus, it is important to preserve those circumstances to provide continuously them. Thus, the purpose of this paper is to grope a growth direction of residents' public space for the elderly to include them to their community through a socially integrated way by grasping present condition of apartment residents' public space's facilities and to be used practically as a basic housing environment data to raise quality of community life.

Background and Aims: Herbal drugs and traditional medicines have lately attracted considerable attention by global pharmaceutical corporations because the conventional chemical drugs didn't work well for many chronic diseases or intractable diseases. The government of Korea is also supporting to develop the new drug which is high value added product, and the natural medicine including herbal medicine(or Traditional Korean Medicine) have a significant presence in this field. non-clinical pharmacology/toxicology study and clinical trial are the two major criteria which estimate efficacy and safety for registration of new drugs. All of the pharmaceutical companies producing herbal medicine and the academic and the academic world of Tradition Korean Medicine have the will to develop new herbal drugs, but there are obstacles that they have neither experience nor guideline about clinical trial. Therefore for developing new herbal drugs, it is necessary to research the present conditions and comprehensive systems about clinical trial in Northeast Asian countries China, Taiwan and Japan because they have the common background with Korea in traditional medicine fields. Methods : The present state of clinical trial for herbal medicine in Korea was investigated. And then, those in China, Taiwan, Japan was also investigated. Results and conclusions : There are significant differences among 4 Southeast Asian countries Korea, China, Taiwan and Japan each in present condition, purpose, involved comprehensive system including legislation, and actual operation of clinical trial for traditional medicine.

The 2015 revised mathematics curriculum encourages students to use graphs in newspapers and the Internet as materials when teaching graphs, and to experience a series of statistical problem-solving processes that collect, classify, organize, graph and interpret data. The graphs that the students learn through traditional textbooks were a single type of graphs. In particular, the graphs of the 5th and 6th grade groups were only increased in numbers, but the basic concepts were repeated in the 3rd and 4th grades. Fortunately, from the 2009 revision curriculum, it is possible to select the graph suitable for the situation while comparing the characteristics of some graphs. In most cases, the graphs used in the real world are presented in the form of a compounded infographics. The purpose of this study is to analyze and analyze the manifestations of information processing competence elements emphasized in the 2015 revised curriculum through the statistical project class using the informal graphic in the fifth grade of elementary school. And we suggested a concrete class plan.

Every Society has it's own ideology and lifestyle and these form its unique aesthetic experience or values. In the paper observing recent, especially in 1980s and 1990s. Korean street fashion that is one way of expressing their values and lifestyle, the aesthetic values related to the morality have been studied. Through the studies using the cafes of Korean street fashion style we can understand the change of morality and fashion style according to the change of socio-cultural environments more deeply. For study methods documentary study and case study were executed. Morality related clothing were defined in detail through documentary studies and for analysis of street fashion from 1980s and 1990s the cases from 'Mut' and 'Ceci' magazines as well as the articles from Chosunilbo, Dongailbo and Maeilkyungje were looked over one by one. By understanding the intrinsic meanings and formal features of resent Korean street fashion, the direction for future fashion designing could be guided, which could satisfy consumers' needs in the rapidly changing world situation. Followings are the results of the study. First, morality of clothing could be defined in detail regarding modesty and extravagance. Modesty could be directly related to exposure of body and norms for appearances and extravagance to fashion oriented, luxury goods or brand name oriented and spending. Second, the exposing body has been accepted and permitted by public even with criticism more easily but they were less generous to values about norms regarding clothing. Third, the change of morality related to modest has happened earlier than the change of morality related to extravagance, which has begun very recently in 2000s.
