Purpose: This study was aimed to investigate the contamination rates of blood culture in a neonatal intensive care unit (NICU) and to examine the clinical characteristics related to the contamination. Methods: Eight hundred thirty cases of blood culture performed from March 2013 to February 2014 were analyzed. We evaluated the contamination rates of blood culture by blood sampling sites and compared the clinical characteristics such as real name system and body weights of the contaminated cases and those of non-contaminated ones. The clinical characteristics were retrospectively reviewed by medical records. Results: The overall contamination rate was 3.6% (30/830). The contamination rates by blood sampling sites were as follows: peripheral vein 15.6% (10/64), peripheral artery 2.6% (20/759), and umbilical arterial catheter 0% (0/7). There was no difference in the contamination rates between cases with and without real name system (P=0.484). However, there were significant differences in the contamination rates by the physicians who performed the culture (P=0.038) and body weight (<1,000 g vs. ${\geq}1,000g$) at the time of blood culture (P<0.001). Conclusions: These results suggest that neonates with a body weight less than 1,000 g have more risks of the contamination of blood culture. Furthermore, there is a necessity to provide blood culture performers with active feedbacks and individualized education plans that can help diminish blood culture contamination rates. Prospective studies in a systematic manner that can be applied in actual clinical settings are needed in order to figure out factors that can diminish the contamination rates of blood culture in NICU.

In this study, a series of site measurement of particulate and gases pollutants at five tunnels were carried out along with case studies to review the suitability of the current road tunnel ventilation design standards. Previous studies by other researchers have shown that the ratios of the level of measurement to the standard were 27.9%, 1.6% and 3.4% for TSP, CO and NOx, respectively. Those measured in this site study shows even lower ratios; the ratios were 2.6%, 0.8% and 0.3%, for TSP, CO and NOx, respectively. The particle size analysis of TSP for the five tunnels shows that PM10 including tire wear and re-suspended road dust exceeded 20.4%. This implies that non-exhaust particulate matter must be taken into account, since the current design standards for the particulate matter (visibility) include only the engine emission. Based on the recent research results, for vehicle emission rate and slope-speed correction factors, revision of ventilation design standards for pollutants is required. WRA (PIARC) also emphasizes the necessity of the ventilation design standards for pollutants. In addition, enactment of a new road tunnel ventilation system operation standard or guideline is strongly recommended when considering the low operating rate of the ventilation system with jet-fans.

The rapid changes in telecommunications have exercised an important influence on the telecommunications law system, including the protection of the privacy. It was a decisive assignment that telecommunications law protected the confidentiality of privacy. But in new digitalized telecommunications circumstance, every steps of the conveyance of the individual informations should be protected, in particular by telecommunications carriers as a subject of the protection of information. EU Privacy Directive in 2003 and the amendment of Communications Act in U. S. A. in 1996 have reflected the necessity of the privacy from a new point of view. In Korea, "Protection of Privacy Act" has been established as general law as to the protection of privacy and "Electronic Communications Net-work Act" and "Location Data Act" have been functioned as special law in telecommunications, and these laws have developed the legal systems about the protection of privacy in telecommunications. Such a legal system could be affirmatively evaluated. But the regulations should be reformed in a way that corresponds to the detailed types of the privacy and it should be devised a method, that the consent of users could be fulfilled practically.

It is very important to use the raw material in a particular field of research or education. Research without raw materials are difficult to prove and often remain hypothesis. The use of the raw material is also important in area studies that study specific areas. However, research of area studies, especially Western history, raw material and historical archives are very important data, but it is difficult to obtain and refer to these data due to physical or spatial constraints. In order to solve this problem, there is a method of collecting and providing historical archives, but it is currently difficult to find a case of providing overseas historical archives as a web system in Korea. Accordingly, in this paper proposes the necessity of collecting historical archives, the method of collection, and the method of digital archiving of collected data structurally and systematically. In this regard, investigate the existing research cases on the archive system and database design, and it description the differentiation between the existing systems and the modeling method proposed in this study. Also, to improve the efficiency of the search, it proposes a method of adding a tag table when database modeling.

The purpose of this study is to explore the necessity and method of the development of modern digital image contents using the story of the literary work 'Guunmong'' by Kim Man-joong. Collective intelligence technique is one of the most recommended. Today, most cultural content development is achieved through the application of digital technology through collaboration of various people from the planning stage to the completion stage. Most prototypes of local cultural contents are developed based on the literary works of artists from the region or background of the region on the works. These local cultural resources can be developed into experiential tourism products and used for the development of local cultural industry. This study first examines the availability of collective intelligence method as a way to effectively develop local cultural contents, and proposes application of image-telling technique and using web-toon characters in digital image contents development. In order to prove the practical applicability of the proposed method, we present an example of cultural contents development of 'Guunmong'. Finally, we propose a new business model based on collective intelligence to develop a system of creation and distribution of the cultural contents through the continuous collaboration.

The overseas calibration sites such as Mongolia used for Korea Multi-purpose Satellite (KOMPSAT-5 or K5), have a disadvantage in that maintenance and repair costs are high and immediate response is difficult when an unexpected problem occurs. Accordingly, the necessity of establishing a domestic SAR calibration site was suggested, but the progress of related research is insignificant. In this paper, we investigated what conditions should be satisfied in terms of backscattering characteristics to construct a site for SAR satellite image quality evaluation and calibration. First of all, it was selected first by applying general indicators such as accessibility and availability among places recommended as satellite image calibration candidate sitesin Korea. Next, three places, site A (Goheung-gun, Jeollanam-do), site B (Jeonju-si, Jeollabuk-do), and site C (Daedeok Research Complex, Daejeon), were selected as the final candidates because they are relatively wide and easy to install AT or CR. Site A, located in Goheung-gun, Jeollanam-do, was best considered in terms of slope measurements, minimum site area to obtain ISLR, uniformity of DN values and backscatter coefficients, interference by strong reflectors, and backscatter clutter level.

I try to formalize the system of modal logic and interpret it in view of constructivism through this study. As to the meaning of a sentence, as we saw, Frege endorsed extensions in view of the fact that they are enough to provide for a compositional account for truth, in particular that (1) the assignment of extensions to expressions is compositional ; (2) the assignment of extensions to sentences coincides with the assignment of truth values. But nobody would be willing to admit that a truth value is what a sentence means and that consequently all true sentences are synonymous. So, if what we are after is meaning in the intuitive sense, then extensions would not do. This consideration has later become the point of departure of modal and intensional semantics. So, it is clear that the language of modal logic do not allow for an extensional interpretation. ${\square}$ is syntactically on a par with ${\vdash}$, hence within the extensional framework it would have to denote a unary truth function. This means that if modal logic is to be interpreted, we need a semantics which is not extensional. The first attempt to build a feasible intensional semantics was presented by Saul Kripke. He came to the conclusion that we must let sentences denote not truth values, but rather subsets of a given set. He called elements of the underlying set possible world. Hence each sentence is taken to denote the set of those possible world in which it is true. This lets us explicate necessity as 'truth in every possible world' and possibility as 'truth in at least one possible world'. But it is clear that the system of modal logic is not only an enlargement of propositional logic, as long as the former contains the new symbols, but that it is of an other nature. In fact, the modal logic is intensional, in that the operators do not determine the functions of truth any more. But this new element is not given a priori, but a posteriori from construction by logicist.

This paper is to make a comparative study between George Sand and Na Hye-sok through their lives and works. The research found that George Sand and Na Hye-sok had similar views about the institution and social system of their age. Both women were aware of importance and necessity of education and the arts but showed a clear distinction between their beliefs in education and the arts. George Sand found that education was an indispensable part of women's lives but found that educationforwomentotheageofSandwasuseless. For this reason she continued to assert a substantial reform concerning women's education. In addition, she argued that everyone should have been given the same opportunities regardless of gender or class. Na Hye-sok, meanwhile, looked at women's education in a more realistic perspective, that is to say to make money. The two women showed remarkable differences in the view of art. This is evident from the presence of a responsibility and a sense of purpose as an artist. George Sand was imbued with a sense of purpose and clarified her own belief at the beginning of her activities as a writer. She wanted to inform the suffering of the weak through her writing and to contribute to build a Utopia where everyone could be happy to live beyond the boundaries of gender. However, Na Hye-sok did not reveal her own clear sense of purpose to her art activities. Art is not just a job - it's a vocation. Na Hye-sok was enthusiastic but didn't have a sense of purpose. She should have had a vocation and a sense of purpose. Na Hye-sok was lacking of responsibilities and obligations as a pioneer of Western painting. If there were a distinct vocation and a sense of purpose to Na Hye-sok as an artist, she would have left a trail as valuable as that of George Sand.

This study was conducted to find out basic facts on educational resources in Korea and see how educators have managed their tasks without educational resource archives. The research had the following steps: 1) finding out how the current state of primary and secondary education resources is managed and type of educational resources via Web search and literature review, 2) conducting a survey to determine archiving priorities according to the value of resources to the users, and 3) engaging in a discussion with experts on merits of establishing an educational resource archive system. Due to sporadic management and restricted use of educational resources produced in Korea, the primary and secondary education resources are not easily available to the public even though the public and private sectors produce significant amount of resources. The survey result on preferred educational resource types for archiving showed the following top three: 1) actual case studies conducted in the field, 2) curriculum related resources, and 3) various textbooks adopted. Considering the value of educational resources and the necessity of archiving agencies, the experts recommended to set up a national archiving system of educational resources. This study hopes to raise awareness of the need to set up educational resource archives as a start.
