Blooms of macroalgae have grown over the planet in recent decades as a possible result of eutrophication of coastal waters. Visually, a bloom forming can be identified by dominant presence of an organism at the expense of others. In mid-January 2014, a forming bloom of red algae was detected on the beach of Garopaba, Santa Catarina State, Brazil. This aroused the interest of tourists and locals as well as the scientific community. Thus, the objective of this study was to characterize and quantify the photosynthetic floating organisms contributing to this phenomenon. In addition, we qualitatively compared algal composition of the bloom to those deposited in the post-beach area and the adjacent rocky shore community. Five sampling points in random patches of floating material were defined. At each point, five replicates were taken with a cube of 32,768 cm³, resulting in a total of 25 samples. Samples were collected in the inner area enclosed by a PVC quadrate of about 900 cm² from the shore and the specimens found in post-beach zone (wrack). Twenty-four taxa of macroalgae were found in the bloom, with Aglaothamnion uruguayense as the dominance one. Ten taxa were found on shore. Only four taxa were found in the post-beach area. The biomass estimated for A. uruguayense in the floating material was 8.35 tons with an estimated area of 52,770 m² . It is possible that this huge biomass value of the bloom is related to the local nutrient intake, and our results reinforce the necessity of coastal integrative management initiatives.

Public health system and public health practice have changed over the past decades as the result of social and epidemiologic changes. New public health concept emphasizes leadership, strategical thinking, systematic planning and effective performance to identify and solve complex health problem In Korea, the role of Health Center has been expanded rapidly. However there is strong suspicion that Health Center can achieve their mission. This paper aims at understanding what is the needed functions of Health Center and which of its aspects needs improvement. The main results of this study are summarizes as follows. District Health Law does not address the core functions of Health Center. The staffs of Health Center have difficulties in prioritizing their services. The recent attempt to restructure Health Center and change delivery pattern of public health services ended with only limited success. To effectively confront threats to the public's health, the three major function of Health Center must be ${\circled}1$ modifying individual behavior and lifestyle, ${\circled}2$ improving social and economic conditions, and ${\circled}3$ reforming health policies. Better results do not come from setting new functions only; they come from understanding and improving the processes that will then leads to better outcome. We recommend that policy-makers focus economic evaluation of public health programs, building and spreading of the scientific evidence of programs, linkage of public health research and public health program. The criteria of delegation of public health service to private sector is urgently needed. Making community health information data available on a routine basis to providers, managers and researchers of public health services helps promote the efficiency of the overall operation of public health system.

This study aims to establish basic data for efficient management of rural water by analyzing regional irrigation facilities and benefitted areas in the statistical yearbook of land and water development for agriculture at the watershed level. For 511 domestic rural water use areas, water storage facilities (reservoirs, pumping & drainage stations, intake weirs, infiltration galleries, and tube wells) are spatially distributed, and the benefitted areas provided at the city/county level are divided by water use area to provide agricultural water supply facilities. The characteristics of rural water district areas such as benefitted area, were analyzed by basin. The average area of Korea's 511 rural water districts is 19,638 ha. The average benefitted area by rural water district is 1,270 ha, with the Geum River basin at 2,220 ha and the Yeongsan River basin at 1,868 ha, which is larger than the overall average. The Han River basin at 807 ha, the Nakdong River basin at 1,121 ha, and the Seomjing River basin at 938 ha are smaller than the overall average. The results of this basic analysis are expected to be used to set the direction of various supply and demand management projects that take into account the rational and scientific use and distribution of rural water and the characteristics of water use areas by presenting a quantitative definition of Korea's agricultural water districts.

The nature of science has been recognized in a great deal in the field of science education. However, only few innovative programs are offered for science-gifted students to improve their recognition of the nature of science. The current study describes and analyzes science-gifted students' understandings of the nature of science (NOS). In addition, the study looks into contradictory views among the aspects of NOS, which are fundamental data in constructing target programs on NOS for science gifted students. Data used in this study were collected from 73 middle school science-gifted students using an open-ended questionnaire, VNOS. The results of this study showed that the participants' understanding of NOS was significantly distributed on naive or transition view except for 'tentative NOS', and the results revealed inconsistent view among the aspects of NOS. This study proposes two suggestions to enhance the recognition of science-gifted on NOS of science to informed state and to have consistent perspectives with other areas. First, the role of experiment has to be changed-it should be the process in constructing scientific knowledge rather than an instrument to check scientific knowledge to transform perspective on experimental data and scientific knowledge. Second, various opportunities must be provided to science-gifted students, so they can experience the culture and community of scientists and science to gain a wider insight of science.

The average increase in life expectancy obtained as a gift of modern science cannot hold itself responsible for extended life's happiness. It admits of no argument that the necessity of social preparation for minimizing bad health and longevity of unhappiness to aged people who are in the state of these continuous growth. Recently, because of an aging trend, targeting on elderly housing expected continuous increased demand in housing market, this study is to comprehend it's characteristic and offer implications. For the characteristic of elderly housing, firstly it needs scientific analysis of related theory and analysis of statistical data. Also this study aims to look through and suggest an alternative included the special matters of Korean society with advanced foreign country's analysis of an alternative. And judging from economic characteristics of elderly housing to be presented as an important factor, choices of housing according to economic level are anticipated to show different forms. In future, to supply elderly housing, therefore, the introduction of the concept of housing providing various opportunity of choice is necessary. If studies proceed through expanded alternative, it is judged to be able to draw more varied results in elderly housing. Also, if going along with political dimension study, it is expected to offer more specific and effective solutions of the problem of elderly housing.

Various experiments using zebrafish have been highlighted recently in the scientific community. Because it is possible to conduct practical experiment from various neurological research to area of genetic study or toxicity experiment. However, gender difference effects are nearly not considered. If the gender differences of zebrafish are considered it is possible to obtain more accurate data. In this study, zebrafish which have different genders were compared each other with NMR-based metabolomics. The extracts of male and female zebrafish were measured by 600 MHz NMR spectrometer. Statistical analysis and target profiling were conducted. As a result, muscle related metabolites were observed in male zebrafish and nerve related metabolites were observed in female zebrafish.

The purpose of this study was to examine the ecological characteristics of herbaceous communities by systematic and scientific analysis of their structure and diversity in the Midongsan Arboretum and to offer raw data for a long-tenn monitoring study. The importance value and diversity index of species appearing in twenty plots from July to September, 2004 were analyzed and a management plan for these communities is presented. Vascular plants were represented by 60 taxa of 23 families, 51 genera, 50 species and 10 varieties. Based on the results of importance value analysis, the most dominant species was Artemisia princeps var. orientalis, followed by Setaria viridis and Erigeron canadensis. The diversity index analysis showed that plot no. 5 had the highest H' and H'_{max}$(2.0135 and 2.6391). It's species composition was comparatively more diverse and it's structure more stable than other plots. Artemisia montana and Dactylis glomerata showed the highest correlation between species. Because herbaceous communities are important biological habitats and provide important function in environmental conservation, it is important to properly preserve these communities. At the same time, in order to preserve genetic resources and improve spatial function, it may be necessary to consider removing herbaceous communities in certain areas. In the future, the relations between physicochemical soil properties and herbaceous communities should be examined and community movement should be studied.

The public library and micro-library as institutions of social education have been greatly developed under the influence of the library law enacted 011 Octob~r 28,1963 and the micro-library movement begun in 1961. However, they have still yet many problems to solve in order to accomplish their purpose effectively. As compared with the staff and library materials, buildings are 1norc. than a match for the others. Although many facilities are not complete enough to serve the public, people do not make the best of the facilities in both the public libraries and micro-libraries. The cause of such a result ~vould be taken from a reason that the founders of the libraries could not concentrate their intcrest on the staff and materials, for they were bent on the establishment of external facilities of the libraries. The poorer materials and facilities are, the more effort a2d better quality of the staff are required for their best utilization. As it is the information center of the community, the management of a library should be scientific and reasmable. In addition, librarians have to do their best to serve the public with the spirit of Christianity under the more active suppxt of the government. Finally, institutions of social education in this comn~unityin cluding public libraries and micro-libraries might establish a mutual cooperative organization for more effective library service.
