The previous HL7 interface should be developed as a separate package or conversion module for each version to process HL7 messages from different versions. This study designed and developed an HL7 parser compatible among different versions based on the requirements of compatibility defined in HL7 V2.5. According to the structure of the parser, the inheritance concept in object-oriented programming was adopted so that the class object of the HL7 message from the lower version could be inherited to the class object of the upper version. Therefore, every version's HL7 messages could be processed using only the upper class' object regardless of the version. To evaluate the compatibility of the developed parser, 700 data sets about inpatients with rheumatoid arthritis were used. The 700 cases underwent the compatibility test successfully. In the near future, further research on the Inter-compatibility HL7 parser is planned.

As compared with other cutting types, the ball end milling process causes a complexity in cutting system and a falling-off of machinability. In order to increase the productivity and efficiency in th NC machining of sculptured surfaces, this study carried out the qualitative linearized evaluation about the ball end milling system and applied their practical expressions to the technological processor at the cutter path planning stage. The evaluated expressions were proved to be adequate for practical use from an accuracy point of view and the estimation models were applied to sculptured surface machining processes for finding variable machining conditions. Consequently, it was recognized that variable machining conditions bring about the dispersion of force system and the reduction of machining time by more than 50%.

There have been 20 cases of trade disputes related to zeroing in WTO. In these day, it was judged that the use of zeroing in the calculation of dumping margin is against ADA. Recently, WTO decided in favor of Korea in regards to Korea's stainless steel products on January, 2011. There finally was a high possibility of zeroing being changed. In December 2010, the American government announced it would revise zeroing system through an federal register. Many researchers, such as Linsey and Ikenson(2000), William W. Nye(2009) already clarified through empirical analysis that no use of zeroing leads to a large decline in the margin of dumping. If zeroing is abolished in the future, the margin of dumping imposed on Korea's stainless steel will drop sharply. According to this empirical study, the margin of dumping in 6 stainless steel among 12 products commodities subject to Anti Dumping regulation from US reduced below de-minimis or 3%. These stainless steel is likely to be excluded from the Anti Dumping regulation through review investigation and Korea's export of steel to America is expected to be increased steeply in the future.

The prevalence and serotype of food-borne pathogens was investigated from 888 samples of chilled meat, 222 samples of packed frozen meat and 117 samples of imported frozen meat during the period from March 1996 to October 1998. Isolation rates of pathogens associated with food poisoning were revealed in order of Staphyloccus aureus, Campylobacter jejuni /coli, Listeria monocytogenes and Salmonella spp, but Escherichia coli O157:H7 was not isolated in all of the meat samples. Amusingly, Campylobacter jejuni /coli were isolated highly in refrigerated meat, but was not isolated in packed frozen meat. L. monocytogenes was encounted higher isolation frequency in packed frozen chicken meat than in refrigerated chicken meat. In the distribution of serotypes of isolates, most isolates of Sta. aureus classified as enterotoxin type C and D. All of the Salmonella spp. isolated from pork were diagnosed group A and most of isolates from chicken meat were grouped B and D. Most of L. monocytogenes isolated from chicken meat were grouped type 1 and a few number of isolates classified as type 4.

As a first step in developing a more effective and robust approach to faculty research performance assessment, this study analyzed the existing faculty research assessment methods by comparing Korean universities' research evaluation standards, National Research Foundation of Korea's (KRF) standard for assessing research proposals, and various bibliometric measures. The study data included research evaluation standards of KRF along with 27 Korean universities with Library and Information Science (LIS) department, and the publication data of 183 LIS faculties in Korean universities from 2001 to 2015, which consisted of 3,863 papers 16,978 citations. After the comparative analysis of research evaluation standards, the study examined the rankings of institutions and faculty produced by applying the collected standards and bibliometric metrics to the publication data. The study showed that Korean university standards for research evaluation, which aim to consider both productivity and impact of faculty research, differ from similar bibliometric measures such as h-index, and the difference could significantly impact the assessment of faculty research performance.

With the rapid growth of the Internet, millions of indiscriminate advertising SMS are sent every day because of the convenience of sending and receiving data. Although we still use methods to block spam words manually, we have been actively researching how to filter spam in a various ways as machine learning emerged. However, spam words and patterns are constantly changing to avoid being filtered, so existing machine learning mechanisms cannot detect or adapt to new words and patterns. Recently, the concept of Lifelong Learning emerged to overcome these limitations, using existing knowledge to keep learning new knowledge continuously. In this paper, we propose a method of spam filtering system using ensemble techniques of naive bayesian which is most commonly used in document classification and LLML(Lifelong Machine Learning). We validate the performance of lifelong learning by applying the model ELLA and the Naive Bayes most commonly used in existing spam filters.

In recent years, online brand communities, whereby firms and customers interact freely, are emerging trend, because customers' opinions collected in these communities can help firms to achieve their innovation effectively. In this study, we examined whether customer opinions containing negative emotions have influence on their adoption for organizational innovation. To that end, we firstly classified negative emotions into five categories of detailed negative emotions such as Fear, Anger, Shame, Sadness, and Frustration. Then, we developed a lexicon for each category of negative emotions, using WordNet and SentiWordNet. From 81,543 customer opinions collected from MyStarbucksIdea.com which is Starbucks' brand community, we extracted terms that belong to each lexicon. We conducted an experiment to examine whether the existence, frequency and strength of terms with negative emotions in each category affect the adoption of customer opinions for organizational innovation. In the experiment, we statistically verified that there is a positive relationship between customer ideas containing negative emotions and their adoption for innovation. Especially, Frustration and Sadness out of the five emotions are significantly influential to organizational innovation.

Plant regeneration via organogenesis from leaf and stipule explants of micropropagated shoots of strawberry (Fragaria $\times$ ananassa cv. Suhong) was achieved. Leaf and stipule explants were detached from shoot-tip cultured shoots and cultured on MS medium with various combinations of BA and NAA under light or dark condition. Shoot regeneration from leaf explant was observed after 3 weeks in culture and was good at the high ratio of BA and NAA among various combination treatments. The highest shoot regeneration frequency from leaf explants was obtained with 1.0 mg/L BA and 0.1 mg/L NAA, in which 31.1% shoot regeneration frequency(1.7 shoots per leaf explant) was yielded. In case of stipule explants, shoot regeneration was largely affected by plant growth regulators during incubation under dark condition for initial 4 weeks but not under continuous light condition. The combination treatment with 2.0 mg/L BA and 0.1 mg/L NAA showed the most excellent shoot regeneration from stipule explants, where 44.4% regeneration frequency(4.0 shoots per explants) obtained. Regenerated shoots were rooted on MS medium with 0.1 mg/L NAA after shoot elongation, and the plantlets regenerated were transferred to soil mixtures with vermiculite and perlite for acclimation.
