Hugo $H\"{a}ring$(1882-1952) belonged to that special generation of architects born in the 1880s which became responsible for the establishment of Modern Movement in the 1920s as W. Gropius, Mies van der Rohe and Le Corbusier, etc. Although he have been overlooked by many historian, He was a key figure of the Modern architecture and as the main theorist for Organic stream in German architecture. He is well-known for his theory of 'Neues Bauen(New Building)', the organic functionalism that is epitomized as the design process from the inside outwards, starting with the life-processes of dwelling. So he argued that the builder must become aware of the life process his building is to serve, and he should not impose a form but try to find the form. These concepts are expressed well in his key-words, the 'Organwerk(organ-work)' and 'Leistungsform(form as achievement)'s. $H\"{a}ring's$ theory can be found in the short early essay, 'Wege zur Form(approaches to form)' of 1925. But His concept of 'function' is based on the speciality and individual identity that concerned him from the start, not purely pragmatic aspects. After 1940s his theory moved increasingly in this direction. He defined this as the transition from 'Organwerk' to 'Gesetaltwerk', from mere anatomy to essence, being, personality, life. It suggest that Hugo Haring's idea of Gestalt is a dimension of mystical or symbolic meaning. This paper Is about the way in which this theoretical transition can be parallel with contemporary philosophers as E. Cassirer's philosophy of symbolic forms and M. Heldegger's phenomenology. And the key example of this viewpoint is (1921-1926) near Lubuk in Germany, with its 'cowshed' of pear shaped plan devised around the requirements and rituals of farm. This study presents the symbolic conception of Hugo $H\"{a}ring's$ theory can propose the ability of a symbolic intuition as a view that re-integrate technical thinking with knowledge of other kinds beyond the immediate material.

A year has passed since the nuclear power plant accident in Fukushima on March 11, 2011, and a survey for public perception on radiation by Korean people has been made. The methodological design was based on a quantitative survey and a frequency analysis was done. The analysis objects were survey papers (n=2,754pcs) answered by random ordinary citizens chosen from all over the country. The questionnaires, and study tool, were directly distributed and collected. A total of 40 questionnaires using a coefficient of Cronbach's ${\alpha}$ per each area was 'self perception of radiation' (0.620), 'radiation risk' (0.830), 'benefit from radiation' (0.781), 'radiation controlled' (0.685), 'informative source of radiation' (0.831), 'influence degree from Fukushima accident' (0.763), showing rather high score from all areas. As the result of the questionnaires, the knowledge of radiation concept was 69.50 out of 100 points, which shows a rather significant difference from the result of 'know well about radiation' (53.7%) and 'just know about radiation' (37.40%). According to the survey, one of the main reasons why radiation seems risky was that once exposed to radiation, it may not have negative impacts presently but, the next generation could see negative impacts (66.1%). About 41% of our respondents showed a negative position against the government's report on radiation while 39.5% of respondents said that we should stop running nuclear power in light of Fukushima nuclear power plant accident. This study was done for the first time by Korean people's public perception on radiation after the Fukushima nuclear power plant accident. We expect this might have significant contributions to the establishment of the government's policy on radiation.

With the increase of using pesticides, pesticide poisonings become more frequent. In the previous epidemiological study on pesticide poisoning and the reports of the authorities concerned, it is carefully affirmed that pesticide poisonings are caused by farmers' ignorance and negligence in using the pesticides. But the pesticide poisoning should be taken into account in terms of the person who sprays the pesticides, its spraying process, farming style and farmers' socio-economic conditions. And based on the understanding mentioned above, preventive measures for pesticide poisoning should be established. In this socio-medical point of view, this study examined the public health problems caused by using pesticides and the treatment of pesticide poisoning, based on the interviews with farmers in a area of Kyunggi-Do about the spraying process of pesticides, poisoning experiences and its treatments. The results are as follows ; 1) The style of spraying pesticides in the target area is mostly an individual one, not cooperative one. And the subjects of spraying are householders, whose educational backgrounds are beneath notice. More than 2~5 of the subjects are women or old men of 60 years old or so. These are seen to derive from the socio-economic status of Korean agricultural families; their younger generation's moving to greater cities and their petty farming styles. 2) As for the safety measures for the spraying of pesticides, those which have nothing to do with the economic, problems such as efficient spraying and productivity, are well obeyed. On the other hand, some safety measures as the use of safety devices, and spraying time, the degree of dilution of pesticides and the spraying method In windy days, are not obeyed very well, for to keep those makes spraying difficult to do and productivity worse. These facts indicate that the safety measures for using pesticides must be directly concerned with the spraying process, farming style and farmers' socio economic status, rather than the subject's knowledge or carefulness. 3) Even In cases of poisoning they do rarely consult the doctors. This is caused by the problem of their locality and transportation since one should pass away a day even in the busiest season to consult doctors, and by their low socio-economic status. 4) The epidemiological studies on pesticide poisonings should be necessarily led to a socio-medical one which are concerned together with the spraying process of pesticides, farming style, farmer's socio-economic status and discrepancies in public health policies between agricultural communities and urban ones.

There are many difficulties to develop a mobile contents due to many constraints on mobile environments. It is difficult to make a good mobile contents with only visual reduction of existing contents on wire Internet. Therefore, it is essential to devise the data representation and to develop the authoring tool to meet the needs of the mobile contents market. We suggest the compact mobile contents to learn Chinese characters and developed its authoring tool. The animation which our system produces is realistic as if someone writes letters with pen or brush. Moreover, our authoring tool makes a user generate a Chinese character animation easily and rapidly although she or he has not many knowledge in computer graphics, mobile programming or Chinese characters. The method to generate the stroke animation is following: We take basic character shape information represented with several contours from TTF(TrueType Font) and get the information for the stroke segmentation and stroke ordering from simple user input. And then, we decompose whole character shape into some strokes by using polygonal approximation technique. Next, the stroke animation for each stroke is automatically generated by the scan line algorithm ordered by the stroke direction. Finally, the ordered scan lines are compressed into some integers by reducing coordinate redundancy As a result, the stroke animation of our system is even smaller than GIF animation. Our method can be extended to rendering and animation of Hangul or general 2D shape based on vector graphics. We have the plan to find the method to automate the stroke segmentation and ordering without user input.

The enhancement effects of sea mustard extract (SME), starfish collagen peptide (SCP) and a mixture of the two (MIX) on skin activity were evaluated to investigate the possibility of using marine-derived extracts as cosmetic additives. The anti-inflammatory activity, whitening activity and skin elasticity activity of the extracts were analyzed to evaluate their skin-activating effects. Inhibiting the generation of nitric oxide (NO) and the tyrosinase and elastase inhibitory activities were assessed as the bio-markers for evaluating skin activity. SME, SCP and MIX did not show cytotoxicity within the concentration range of 1.0-50 ㎍/mL. In addition, SME, SCP and MIX all increased NO production and the tyrosinase and elastase inhibitory activities in a concentration-dependent manner. The activity of MIX was significantly increased compared to that with using SME or SCP alone. Taken together, when natural extracts are applied as cosmetic additives, the results demonstrate that using a mixture of SME and SCP may have a greater synergistic effect than that when using only a single extract. Therefore, this study contributes to the knowledge about the kinds and composition of several natural extracts when they are used as cosmetic additives.

Korea Ministry of Knowledge Economy has estimated that wind power (WP) will be occupied 37% in 2020 and 42% in 2030 of the new energy sources, and also green energies such as photovoltaic (PV) and WP are expected to be interconnected with the distribution system because of Renewable Portfolio Standard (RPS) starting from 2012. However, when a large scale wind power plant (over 3[MW]) is connected to the traditional distribution system, protective devices (mainly OCR and OCGR of re-closer) will be occurred mal-function problems due to changed fault currents it be caused by Wye-grounded/Delta winding of interconnection transformer and %impedance of WP's turbine. Therefore, when Double-Fed Induction Generator (DFIG) of typical WP's Generator is connected into distribution system, this paper deals with analysis three-phase short, line to line short and a single line ground faults current by using the symmetrical components of fault analysis and PSCAD/EMTDC modeling.

The purpose of this study was to develop problem-solving inquiries for the science gifted and to analyze the effects of problem-solving inquiries. The problem-solving inquiries were composed of scientific knowledge, scientific inquiry skills and creative thinking. The problem-solving inquiries were applied to the science gifted attending the institute of the gifted education. The test of science-creative problem solving (TSCPS) was used to know effects of improvement of science-creativity and the result of TSCPS showed the improvement of science creativity. The analysis of student-student dialogues during experiments showed that the type of dialogue was different on the type of problem-solving inquiry. The dialogue of convergent thinking was frequently showed up on the problem-solving inquiry needed logical thinking whereas that of divergent thinking on the problem-solving inquiry needed idea generation. The problem-solving inquiries had a positive effects on the improvement of the science-creativity.

While science museums, whose functions consist traditionally in collecting, preserving, researching, and displaying science-related objects, present scientific knowledge, figures, or tools in the historical context, science centers give more emphases on science education by exposing interactive exhibits to their visitors. However, neither objects-oriented exhibits nor hands-on technologies can provide museum visitors with the full insight into modem science in terms of its complicated relationships to politics, economy, culture, art, risk, and environment. This paper argues that for the 21st century we need to establish a new kind of science museum through the critical examination of its previous kinds - science museums and science centers. In the first part of this paper, the history of the first and second generations of science museums, including their recent trends in science centers, in the West will be elaborated. Secondly, the development of national science museums in Korea will be discussed specifically for the understanding of Korean science museums. The next part of this paper will seek for the possibilities of the third generation of science museums through three examples, which show interdisciplinary, contextual, and institutional approaches to change science museums or science centers. Fourthly, the social function of science museums as 'forum' will be discussed in relation to promoting public 'participation' of science as well as public 'understanding' of science. As a conclusion, some practical suggestions and conceptual guidelines will be proposed for the future Korean national science museum.

In this paper, we propose an asynchonous ICI (Inter-Cell Interference) mitigation techniques for 3GPP LTE MIMO-OFDMA down-link receiver. An increasing in symbol timing misalignments may occur relative to sychronous network as the result of BS (Base Station) timing differences. Such symbol synchronization errors that exceed the guard interval or the cyclic prefix duration may result in MAI (Multiple Access Interference) for other carriers. In particular, at the cell boundary, this MAI becomes a critical factor, leading to degraded channel throughput and severe asynchronous ICI. Hence, many researchers have investigated the interference mitigation method in the presence of asynchronous ICI and it appears that the knowledge of the SCM (Spatial Covariance Matrix) of the asynchronous ICI plus background noise is an important issue. Generally, it is assumed that the SCM estimated by using training symbols. However, it is difficult to measure the interference statistics for a long time and training symbol is also not appropriate for MIMO-OFDMA system such as LTE. Therefore, a noise reduction method is required to improve the estimation accuracy. Although the conventional time-domain low-pass type weighting method can be effective for noise reduction, it causes significant estimation error due to the spectral leakage in practical OFDM system. Therefore, we propose a time-domain sinc type weighing method which can not only reduce the noise effectively minimizing estimation error caused by the spectral leakage but also implement frequency-domain moving average filter easily. By using computer simulation, we show that the proposed method can provide up to 3dB SIR gain compared with the conventional method.

In the period of great change in human society, a change in educational services is also necessary. Thus, the current research investigates a new model of educational services to prepare people to be successful in an era of service and the fourth industrial revolution. We analyzed all the educational service models from the first educational institution, The Academy, founded by Plato to one of the most innovative institutions, Minerva schools. Then, we designed both an educational institution model and an educational service model that will cultivate and educate prospective students to be multidimensional to fit to the new upcoming eras. Since the era of service in the 21st century is also the era of job creation, we designed models focused on developing the broad knowledge and practical skills need to solve the most complex issues of our time. A new model was designed based on the results of the survey of existing major programs, analysis of the demands of the new generation, competency requirements, and etc. The newly designed conceptual model was improved from study focusing on tools to study that focuses on intrinsic discipline and competence, nurturing dream and imagination. In order to realize the new educational service, we developed technical conditions and a methodology for improving educational service performance. In the future, it is necessary to deepen the study and carry out research on implementing new educational service. In addition, an empirical study of the performance of the new model will also be needed.
