This study was conducted to develop a topping formula for pizza containing Chungkukjang and onion as the main ingredients. The maximum amount of onion was limited to 10.5%, since the pizza crust and toppings would separate if too much water dispelled from the onion tissue during baking. The Chungkukjang was substituted for Bulgoggi, a meat topping. The sensory acceptability scores for the pizza topping decreased as the amount of Chungkukjang increased from 3.6% to 7.3%, due to its unpleasant odor, but scores increased when 1.6% Kimchi powder was added to the Chungkukjang without a significant difference from the control. Thus favorable sensory quality was obtained with a topping formula containing 8.7% Chungkukjang, 10.5% onion, and 1.6% Kimchi powder. The nutrient values of the final pizza products were assessed as follows. By adding the Chungkukjang and onion, crude protein, crude lipid, crude ash, and total dietary fiber contents increased. Moreover, the calorie level of the Chungkukjang-onion pizza was 3.8% higher than that of the control pizza. The amounts of compound amino acids including lysine increased. The free amino acids also increased from 143.3 to 188.6 mg/100 g. The ratio of saturated fatty acids to unsaturated fatty acids changed from 1:0.71 to 1:0.81. For the consumer test, the age groups of the participants were classified as 15-29 years old, 30-39 years old, and 40-62 years old. A positive result on acceptability of the developed pizza was obtained from most of the panelists in all age groups. Over 93% of the 119 responding subjects had purchasing intentions. An, especially, strong purchaging intention was shown in the younger age group of 15-29 year-olds, even though they had a lower preference for the Chungkukjang. Finally, an attribute of satisfaction was induced based on 'health' (79.5%) and 'flavor' (15.7%).

Auto-playing programs are often used in behalf of human players in MMORPG(Massively Multi-player Online Role Playing Game). By playing automatically and continuously, it helps to speed up the game character's level-up process. However, the auto-playing programs, either software or hardware, do harm to games servers in various ways including abuse of resources. In this paper, we propose a way of detecting the auto programs by analyzing the window event sequences produced by the game players. In our proposed method, the event sequences are transformed into a set of attributes, and the Decision Tree learning is applied to classify the data represented by the set of attribute values into human or auto player. The results from experiments with several MMORPG show that the Decision Tree learning with proposed method can identify the auto-playing programs with high accuracy.

According to the development of medical technology, new medical treatments have been dramatically increased as an inevitable consequence, however, it is not easy for medical workers to learn the knowledge that is necessary for new medical treatments and their additions in the medical services. Therefore, it could not be helped increasing the guidelines for applying new medical treatments, and then, the problem would come out whether to attribute the medical negligence to the doctors who did not follow the guidelines when the patient became worse because of his non-compliance. Nevertheless, there is no document to review the problem mentioned above and also no definite precedents. Thus, the civil lawful character and obligation of guidelines on the lawsuit against the medical default have been examined in this studies. The medical negligence is defined as usual doctors violate the care obligation which is demanded for them to follow when they treat patients under the proper medical standard in those days. It is resonable to assume that the matter of guidelines is to decide the level of the care obligation, that means the care which is required of the rational doctors under same circumstances, and in general, the experts' testimonies should be needed in this case. In addition, the issue comes out whether the guidelines can be the standard of the judgement of the medical negligence. Finally, I suppose, the evaluation of the issue depends on who makes the guidelines, what materials are based on, and also depends on whether there is another guidelines in the same disease, what the purpose of guidelines is to save the medical costs or to realize the appropriate medical services, in addition, it depends on how often renew the guidelines, and how wide is the usage of guidelines.

Database Integration problems has been recognized as a critical issue for effective logistics service in logistics environment. However, researches related to effective methodology for this have been studied theoretically in the DB schema integration, are insufficient in the side of the system realization. The aim of this paper is to present a schema integration technique to integrate DB using XML( eXtensible Markup Language) in the part of practical DB integration, a quantitative methodology for the identification of conflict that is a representative problem on database integration. To achieve this aim, we extracted the entity name and attribute name from DB schema and suggested a quantitative methodology to easily fine name conflict that frequently give raise to a trouble when schema integration, based on the level of semantic similarity between attributes and entities.

In this paper, we propose FAS model for establishing trust based on digital certificates in Grid security framework. The existing RBAC(Role Based Access Control) model is extended to provide permissions depending on the users‘ roles. The FAS model is designed for a system independent integrated Grid security by detailing and extending the fundamental architecture of user, role, and permission. FAS decides each user’s role, allocates access right, and publishes attribute certificate. FAS is composed of three modules: RDM, PCM, and CCM. The RDM decides roles of the user during trust negotiation process and improves the existing low level Grid security in which every single user maps a single shared local name. Both PCM and CCM confirm the capability of the user based on various policies that can restrict priority of the different user groups and roles. We have analyzed the FAS strategy with the complexity of the policy graph-based strategy. In particular, we focused on the algorithm for constructing the policy graph. As a result, the total running time was significantly reduced.

PURPOSES : This study was initiated to estimate the utilities of usage attributes of BRT and Bimodal Trams using a conjoint analysis method in order to identify the important features pertaining to the use of BRT and Bimodal Trams. METHODS : For this purpose, important attributes and those level in the use of BRT and Bimodal Trams in the city of Sejong were identified. Next, a profile questionnaire pertaining to BRT and Bimodal Trams was designed for the conjoint analysis, and a survey was conducted in the city of Sejong. Using SPSS software, conjoint analysis was performed to identify the important attributes vis-$\acute{a}$-vis the use of BRT and Bimodal Trams in the city of Sejong. Finally, the utilities for individual attributes were calculated based on the models estimated by the conjoint analysis. RESULTS : The results of the conjoint analysis were used to identify the important attributes. With regard to the usage of BRT, users indicated that fare was the most important attribute with the highest utility. In the case of Bimodal Trams, the users indicated that the number of seats and internal environment were the most important attributes with the highest utilities. CONCLUSIONS : Based on the results of the conjoint analysis, the important attributes pertaining to the use of BRT and Bimodal Trams in the city of Sejong were identified. Our study indicates that BRT in the city of Sejong needs to be upgraded to improve the utilities of the important attributes.

Position encoding is a method of applying weights according to position of words that appear in a sentence. Pointer networks is a deep learning model that outputs corresponding index with an input sequence. This model can be applied to coreference resolution using attribute. However, the pointer networks has a problem in that its performance is degraded when the length of input sequence is long. To solve this problem, we proposed two contributions to resolve the coreference. First, we applied position encoding and dynamic position encoding to pointer networks. Second, we stack deeply layers of encoder to make high-level abstraction. As results, the position encoding based stacked pointer networks model proposed in this paper had a CoNLL F1 performance of 71.78%, which was improved by 6.01% compared to vanilla pointer networks.

The study aimed to explore media use by digital natives in Korea. To date, Korea is a country that has both the highest level of digital natives and fastest Internet access in the world. The study also intended to deeply understand the simultaneous activity use of different media and determined the characteristics of Korean digital natives. Based on Korea Media Panel Data for 2015, analyses of the digital natives' traits of time-space, media use, and simultaneous use of media were made through a statistic multi-correspondent method. The results showed that spatial attribute and media use of digital natives are homogeneous in pattern and the degree of simultaneous use of media seems to be limited in type. Moreover, the study suggested the new concept of digital natives' media use and the need for various studies showing the relationship between media use and the Internet generation.
