The objective of this study was to analyze the temporal and spatial characteristics of agricultural drought by tracking the daily reservoir storage in Chungnam province. All daily records of the percent of reservoir storage from 2000 to 2015 were collected for 130 irrigation reservoirs from the RIMS (Rural Infrastructure Management System). The temporal change of province-wide average reservoir storage and the statistics showed that the annual average and minimum percent of reservoir storage in 2015 were extremely low like as those in the historical drought years of 2001 and 2012. The minimum reservoir storage on record was a 41 % at the end of September and remained far less than its historical average even until the end of the year. Furthermore, the annual average reservoir storage (68.3 %) recorded the lowest on record since 2000. In addition, about half of 130 major irrigation reservoirs in Chungnam fell into the risk of water shortage below 30 % full, and, in terms of annual minimum reservoir storage, the 79 reservoirs yielded lower storage in 2015 comparing with the measured in another drought year, 2001. On the other hand, irrigation reservoirs of comparatively worse storage condition revealed to be mostly located on the inside, such as Cheongyang-gun and Hongsung-gun. Conclusively, the low reservoir storage, still far below average even on December 2015, induced a serious concern about that more extreme drought would happen in the next spring.

Change of the energy used in a house can be separated from LNG, and electric power. The electric power consumption of a house is more increasing than LNG. The interest for electric houses is rising due to energy saving and low carbon emission. Accordingly, the amount of energies and cost are analyzed consumed in a house using cumulative energy consumption. The result of analysis, amount of electric power, is more increase. In comparison, the use volume of city gas is more decrease. In this paper, the use volume of energy resource is analyzed using historical energy consumption data in the past 25 years. In addition, expected electrical power and heating energy is analysed adopting an Electric Residence.

This study examines the characteristics of Korean journalism ethics as job ideology by analyzing the specific conditions revealed in the historical process of the construction of Korean journalism ethics, focusing on the change of social relationships which intervene in the construction of journalism ethics. By this interpretation, this study proposes the desirable directions in journalism ethics discussion and practice strategies in the journalism field. Therefore this study analyzed the historical process and the development phase of discourse in journalism ethics in which the job position of Korean journalists have changed. In result, this study found that the discourse of Korean was used for the instrumental and rhetorical means to cope with the outside pressure in the lack of occupational self-control which becomes the premise of ethics. Because of this, the Korean journalism ethics characterize the rhetorical feature of ethical code, the structured separation of practice from cognition, the conceptual confusion of responsibility from ethics.

This article describes the major themes to change in historical and philosophical perspectives of science education that lead the US and Korean science curriculum reform movements since 1957. Inquiry teaching and criticism of teaching science as inquiry in the late 1950s and the 1960s, Science-Technology-Society (STS) Curricula, and Science Literacy and the 1980s science literacy crisis are discussed. In the US, three major curricular projects as responses to the scientific literacy crisis are exemplary such as the Project 2061 sponsored by the American Association for the Advancement of Science, the Project on Scope, Sequence, and Coordination (SS&C) initiated by the National Science Teachers Association (NSTA), and the National Science Education Standards (NSES) published by the National Research Council. To identify how each set of national content standards differ, we compared specific content standards related to the theory of plate tectonics in Earth and Space science in grades 9-12 over the three national standards: Benchmarks of AAAS, NSES of the NRC, and SS&C of the NSTA. Against this historical background of the US science education reform movements, the curriculum reform movements in Korea is briefly discussed. In general, Korean science curriculum reform movements have reflected and resembled the recommendations of the US reform movements. In addition, it is important to note that throughout the history of curriculum revision in Korea, there have been continuing pendulum swings between a theoretical, discipline-centered curriculum and a liberal, humanistic, and student-centered curriculum, which pays more attention to students in terms of their interest and psychological preparedness. In conclusion, the sixth and seventh national science curriculum revisions reflect rather a student-centered movement by reducing technical and sophisticated topics, taking constructivism learning theory into consideration, and adding more STS related topics.

" Analyzing on an object in the sphere of domestic law with the method of international law" has been already on the horizon in international law. For the lawyers of international law and space law, it is quite natural that they utilize the method of international law, whatever objects they may choice. The reason is that the characteristic of international law do not depend upon object in itself, but depend upon method in itself. The object of this paper is the idea of Peaceful Use(IPU or PU) in Japanese Space Policy. The method to be applied to this analysis is the international law's interpretation theory on legal principles, i.e., the method of international law. One of the aims of this paper is to explain critically the need of review on IPU in Japanese Space Policy; in particular with respect to the positive reconstruction of IPU through historical analyzing on the transfiguration and the mere shell of the Post-War Japanese Pacifism(PJP) as the starting point of IPU The historical process of the transfiguration and the mere shell is as followed .i.e.," from the ultranationalism in the pre-war Japan to PJP in the post-war Japan, from PJP to IPU, and from IPU to IPU's regression. In particular with respect to the interpretation theory, the meaning of the teleological, aims and objects school's approach on the interpretation of legal principles(P) has been emphasized. The reason is that the promising development of IPU will be realized by cooperating with the interpretation theory on P in international law. At the end of the beginning, I'd like to quote K. Marx's thesis in order to make the positions and missions the lawyers of international law and space clear. It is as follows, i.e.," THE PHILOSOPHERS HAVE ONLY INTERPRETED THE WORLD IN VARIOUS WAYS - THE POINT, HOWEVER IS TO CHANGE IT.

Present work aims to analyse the spatio-temporal distribution of Korean bamboos. The northern limit of Korean bamboo species occurs at Baekryung Island(124°10'E, 37°55'N), Hoochang(41°22'N) and Myungchon(129°41\`E, 41°10'N). The presence of bamboo fossils in Korea dates back from Tertiary, but widespread use of bamboos can be noticed since 1454. Reconstructed ranges and temporal changes of bamboo, based upon the eight historical records from 15th to 20th centuries, indicates that both climatic and anthropogenic factors were responsible for the changes of distributional range. The spread of bamboos was balanced by its disappearance due to regional development, and the total bamboo area showing little change. Due to the tendency to spread extensively by means of underground stems, bamboos often invade adjacent forests and disturb natural vegetation. Proper management and conservation strategies, therefore, are required for the maintenance of rural landscape.

This study discusses characteristic of spatiotemporal changes of the sand barrier in the Nakdong estuarine for the last century, focusing on geomarphologic evolution and mobility of sand barriers in the view of coastal engineering. The Nakdong estuarine, the research subject, has a complexly changing natural environment by interaction between ground and marine elements such as ocean wave, tidal current, sediment, etc. Moreover, recently, unnatural geomorphologic changes (e.g., seaside reclamation, new harbor construction, etc.) has been radically increased in this area with increasing desire for coastal development. Because of this, its sand barrier has developed quite unstable condition. Therefore, to identify the development process of geomorphologic changes in this area, required is a close examination on historical characteristics of spatiotemporal changes of the sand barrier in relation to surrounding seaside reclamation and physical environmental changes. This study, based on the marine charts published in between 1927 and 1995 year, analyzes the length and area of the sand barrier for the last hundred years, and investigates the cause of the changes by looking into the change of water depth for the last two years and doing ocean-physical site observations. In conclusion, the sand barrier of the Nakdong estuarine expands toward the open sea by $7.4{\sim}26m$ in annual average, maintaining a fixed distance of $1,241{\sim}1.279m$, and its area is expected to increase about $2.8km^2$ annually. This is characterized by the wocean wave from the open sea and the discharge of Nakdong River.

The second part of this study is to typify plural sexuality articulated with fashion images in men's and women's popular fashion magazines in Korea since 2000 and ultimately to infer sexual ideology codified in modern fashion by a framework of this study, the socio-semiotic model. From this, sexuality represented in modern fashion was typified as follows: in women's fashion Traditional Femininity, Glamor Femininity, Androgynous Femininity, Babydoll Femininity and Genderless sexuality, while in men's fashion Traditional Masculinity, Macho Masculinity, Androgynous Masculinity, Adolescent Masculinity and Genderless sexuality. The conclusion of this study is as follows: First, modern fashion has been changed from a means expressing gender and class into a sign vehicle representing the new ruling system of age and sexual desire. The binary oppositional sexuality on center of man in the 19 C capitalist period has been gradually pluralized towards the post-capitalist period. Next, mainstream society in Korea is still positioned in the traditional heterosexuality, keeping the vertical power relationship between man and woman even in the post-modern period. However, the fact that both Traditional Femininity and Androgynous Femininity acquire the position of dominant femininity connotes the change of modern femininity. Finally, plural sexuality represented in modern fashion has family resemblance and it shows contextual flexibility within contemporary period as well as a historical context. As a result, sexuality floats with a specific historical and socio-cultural context, and fashion as a material culture represents a masquerade as a identity vehicle, which constructs and de-constructs sexuality at the same time.

This article explores how non-dominant medical practitioners shape their own self-images and the identity of relevant medicine and in what ways fashioning of self-images and accompanying modalities of medical practice informs the social evolution of the medicines at specific times and over specific places, by means of the historical configuration of osteopathy and chiropractic in the UK and the US. Attention is directed onto motivations and pursuits for professional recognition and actual strategies and activities of non-dominant medicines and its practitioners by turning to historical instances such as osteopathy and chiropractic in the UK and the US, not least drawing focus on professional desires with regard to circumstances it faces within and without. Some non-dominant medicines as a way with which to acquire and protect the exclusive monopoly of its knowledge and practical skills, adopted various forms of professionalism project, as dominant biomedical groups pressed up non-dominant medicines by virtue of marginalizing tactics. Meanwhile, non-dominant medicines took somewhat distinctive professionalisation strategies from each other. Strategies they took were diversified depending on medical philosophy, healing modality, the degree of occupational solidarity embodied as forms of medical organisation, and especially vocational aspiration and prospect. Change of socio-medical culture and the state's policy seems to have wielded critical influenceon the determination of the ups and downs of non-dominant medicines. From the perspective of long-term time span, dominant biomedicine eventually did not have much influence on the ups and downs of marginalized medicines in so far as in the case of osteopathy and chiropractic in Englandand the U. S.

After figuring out the function of an amino acid sequence, we can infer the function of the other amino acids that have similar sequence composition. Besides, it is possible that we alter protein whose function we know, into useful protein using genetic engineering method. In this process. an original protein amino sequence produces various protein sequences that have different sequence composition. Here, a systematic technique is needed to manage protein version sequences and reference data of those sequences. Thus, in this paper we proposed a technique of managing protein version sequences based on local sequence alignment and a technique of managing protein historical reference data using Trigger This method automatically determines the similarity between an original sequence and each version sequence while the protein version sequences are stored into database. When this technique is employed, the storage space that stores protein sequences is also reduced. After storing the historical information of protein and analyzing the change of protein sequence, we expect that a new useful protein and drug are able to be discovered based on analysis of version sequence.
