The aim of this study is to demonstrate interaction as a describable field and tries to understand interaction from the perspective of attributes, thus building a theoretical to help interactive designer understand this field by common rule, rather than waste huge time and labor cost on iteration. Since the concept of interaction language has been brought out in 2000, there are varies of related academical studies, but all with defect such as proposed theoretical models are built on a non-uniform scale, or the analyzing perspective are mainly based on researcher's personal experience and being too unobjective. The value of this study is the clustered resource of research which mainly based on academical review. It collected 21 papers researched on interaction paradigm or interaction attributes published since 2000, extracting 19 interaction attribute models which contains 174 interaction attributes. Furthermore, these 174 attributes were re-clustered based on a more unified standard scale, and the two theoretical models summarized from it are respectively focuses on interaction control and interaction experience, both of which covered 6 independent attributes. The propose of this theoretical models and the analyzation of the cluster static will contribute on further revealing of the importance of interaction attribute, or the attention interaction attribute has been paid on. Also, in this regard, the interactive designer could reasonably allocate their energy during design process, and the future potential on various direction of interaction design could be discussed.

Measuring the compressive strength of concrete is a very important factor in the safety review of concrete structures. Concrete compressive strength measurement methods include destructive and non-destructive methods. The destructive method includes the uniaxial compression failure method, and the non-destructive method includes the rebound hardness method and the elastic wave measurement method. In this study, the type of measurement method and the effect of reinforcing bars inside the concrete were tested to examine the relationship between them. Regardless of the type of specimen, the average compressive strength by the elastic wave measurement method among the three experimental methods was greater than the average compressive strength by the other methods. When the specimen type is the same, the standard deviation of the measured values of the elastic wave measurement method is smaller than that of the other measurement methods, so it can be seen that the elastic wave measurement method does not show large variance in the measured values compared to the other two measurement methods. When the average compressive strength according to the test method for each specimen was compared with the average compressive strength of the compressive failure test method, the average compressive strength was measured to be high in the order of the elastic wave measurement method, the compression failure test, and the rebound hardness method. Since the measured values of the compressive strength of concrete are different depending on the method of measuring the compressive strength of concrete and the presence or absence of reinforcing bars inside the concrete, further research is required considering the effect of various concrete covers.

This review is about current Streptococcosis of cultured olive flounder, Paralichthys olivaceus, in South Korea. The main bacterial species are Streptococcus iniae, S. parauberis and Lactococcus garvieae. The occurrence trend has been arranged with published data and seed bank (NIFS) data that was examined with deposited strains and the number from 2002 to 2017. S. iniae and L. garvieae were collected until 2012 and 2002, respectively, but not collected any more after that year. In recent years, the dominant strain of Streptococcosis of cultured olive flounder is S. parauberis. The phenotypic and genetic characteristics of standard strains and isolated strains were examined with published paper. Notably, we describe about distinguishing gross signs and histological signs of 3 types of Streptococcosis in this report. White turbidity of eye, hemorrhage, enteritis and ascites are main signs of S. iniae infection. Darkness of body surface, hemorrhage in somatic muscle and pericarditis are predominant in occasion S. parauberis infection. In occasion of L. garvieae infection, common signs of Streptococcosis are revealed, but these are weak tendency compared with the previous two cases.

Along with an increase in marine activities every year, the frequency of marine accidents is on the rise. Accordingly, various research activities and policies for marine safety are being implemented. Despite these efforts, the number of accidents are increasing every year, bringing their effectiveness into question. Preliminary studies relying on annual statistical reports provide precautionary measures for items that stand out significantly, through the comparison of statistical provision items. Since the 2000s, large-scale marine accidents have repeatedly occurred, and case studies have examined the "accident response." Likewise, annual statistics or accident cases are used as core data in policy formulation for domestic maritime safety. However, they are just a summary of post-accident results. In this study, limitations of current marine research and policy are evaluated through a literature review of case studies and analyses of marine accidents. In addition, the ontology of the marine accident information classification system will be revised to improve the current limited usage of the information through an attribute analysis of boating accident status reports and text mining. These aspects consist of the reporter, the report method, the rescue organization, corrective measures, vulnerability of response, payloads, cause of oil spill, damage pattern, and the result of an accident response. These can be used consistently in the future as classified standard terms to collect and utilize information more efficiently. Moreover, the research proposes a data collection and quality assurance method for the practical use of ontology. A clear understanding of the problems presently faced in marine safety will allow "suf icient quality information" to be leveraged for the purpose of conducting various researches and realizing effective policies.

In this paper, we review the applicability of fog screen to implement 'Spatial Augmented Reality' which displays the image on the whole space of real space or in real space by separating display equipment and user, in contrast to the traditional Augmented Reality. Through three exhibitions and one performance, we confirmed t hat the fog screen, which can be passed through, is a suitable material for implementing the Spatial Augment ed Reality. We found that the hologram production was easier than before because of fog screen. Through the questionnaire survey conducted on performers along with the exhibition, we found that only about half of people know what a fog screen is, and about 10% of the total respondents saw the fog screen. In order to investigate the effect of fog screen on the surrounding space, we conducted an experiment to observe the change of humidity according to the time and distance in the Children's Culture Center of the Asian Culture Center. We found that the humidity within a radius of 5m around the fog screen could increase by 2~3%($6,400m^3$ standard). Thus we provided some safety requirement with fog screen when works made of materials vulnerable to moisture such as paint, paper, and wood are exhibited at the same time with fog screen in the exhibition hall.

Purpose: Premature adrenarche (PA) often leads to polycystic ovary syndrome (PCOS). Higher anti-mullerian hormone (AMH) levels are reported in PCOS. We studied the androgen profile and AMH profiles in Hispanic girls with PA (aged 5-8 years) and age and body mass index (BMI) matched controls. Methods: Retrospective review of electronic medical records of girls who met the inclusion criteria for premature adrenarche were done. Results: PA girls (n=76) were matched to control girls (n=12) for age (mean${\pm}$standard deviation) ($6.7{\pm}1years$ vs. $6.2{\pm}1.3years$) and BMI ($20{\pm}10kg/m^2$ vs. $17.8{\pm}2.7kg/m^2$). Dehydroepiandrostenedione sulfate ($63.3{\pm}51.3{\mu}g/dL$ vs. $29.8{\pm}17.3{\mu}g/dL$, P<0.001) and testosterone levels ($11.4{\pm}4.8ng/dL$ vs. $8.2{\pm}2.9ng/dL$, P=0.001) were significantly higher in the PA group than controls. AMH values (<14 years: reference range, 0.49-3.15 ng/mL) were $3.2{\pm}2.2ng/mL$ vs. $4.6{\pm}3.2ng/mL$ respectively in the PA and control groups and were not different (P=0.4). AMH did not show a correlation with bone age (P=0.1), and testosterone (P=0.9) in the PA group. 17-hydroxyprogesterone levels (17-OHP ng/dL) were $39.5{\pm}30.5ng/dL$ vs. $36.8{\pm}19.8ng/dL$ in PA versus control girls. The concentration of 17-OHP was not statistically different between the control and PA groups. Conclusion: Higher AMH was not observed in PA girls and no correlation with BA and androgen levels was observed.

This study reviews the basics of earthquake preparedness from several archives and international cases of earthquake damage and restoration to establish an earthquake preparedness plan in Korean archives. The results of the study are as follows: first, to establish the direction of an earthquake preparedness plan, the study summarizes the basic characteristics of an earthquake and its damages, as well as applies the key elements of disaster preparedness planning after reviewing its basic principles. Second, the study analyzes four international cases that may have significant implications for the earthquake preparedness plan in Korea. Given this, four international cases present lessons and limitations such as the book dropping of a library in Japan, the collapse of archives in Germany, damaged archives because of a massive earthquake in New Zealand, and earthquake preparedness and recovery plans in cultural heritage sectors. Third, to apply the information from overseas cases to domestic, the study examines the lessons, the key elements of earthquake preparedness planning, and the public record standard for Korean archives through the mutual linking process, as well as issues that should be considered. The issues reviewed in this study could help Korean archives establish a realizable earthquake preparedness plan in the future.

This study deals with the rent-seeking behavior that exist in cultural voucher from the viewpoint of culture and arts management. Art organizations open to consumers, producers and governments of the arts are dependent on the internal and external influence of an open system. Researcher has found rent-seeking in the course of introducing policies and legalization of the cultural voucher business which has been promoted in the direction of democratization of culture or cultural democracy. Cultural voucher business is a legal term. Although the government has increased the budget or tried to change the policies of the cultural voucher business, the implementation of the cultural voucher business has been opposed to the diversity of consumption and equity as the consumption of genre and the concentration of the capital region have increased. These results were structurally related to the process of legalization and rent-seeking behavior in bureaucracy. This study reaffirms that the efficient operation standard of the cultural voucher business is a balance between the choice of the beneficiary, the competition of the supplier, and access to the cultural voucher. And the theory of rent-seeking was applied as a criterion to analyze this balance. Thus, it is suggested that the criteria of evaluation and improvement to check the conservativeness of bureaucrats are needed to establish a legal system applied to the purpose of 'cultural democracy' and 'democratization of culture' ideology and to guarantee individual creativity and autonomy.

This study has its aim to judge both applicability and suitability of recycling of waste soil for the use of farmland amelioration and low-lying farmland reclamation through growth and development experiment and component analysis. As results of physical characteristic evaluation on recycling of waste soil, the classification based on unified soil classification system has investigated as SW and SP affiliation and soil classification has appeared to be a loamy sand. As results of chemical component analysis, pH has appeared to be 7.0~8.4 which is relatively higher than general soil, however, heavy metal has investigated within the 1 region's standard value of soil pollution standards. As results of germination experiment, when using it by mixing recycling soil less than 75%, there is no significant influence on germination, and in the growth and development experiment, when using horticultural bed soil which is mixed with less than 40% of recycling of waste soil, it has confirmed that there is no significance difference with general soil. In case of farmland, the growth disorder of recycling of waste soil rate no more than 40% has shown that it has relatively small influences, and in case of using it by mixing with agricultural soil, it has evaluated to require concrete review of factors which may restrict growth condition including nutrition and pH.

This essay focused on the critical review of Korean National Archives System(KNAS) since 1999. We think that KNAS could establish the backbone with basic records law on 1999. It's right. But it is not enough for explaining the full historical growth. there are some factors below the growth. This essay tried to the basic three factors below. That means the the demonstration discourse, archival system practices, and archiving technologies in the contexts of the unique standard by the basic records law. These three factors have been the powerful engine for the take-off of KNAS since 1999. However, the powerful history has shadows of growth. This essay narrated the shadows by the frame of 'counter-destiny'. The most dangerous shadow is the loss of archival cultures because the KNAS has been composed of efficiency mentality. That means that KNAS has no unique archival culture for citizenship. So, this essay tried to talk about 'Post1999' to Archives Community.
