We have studied statistically about quality difference of Blast furnace slag Type Ⅲ that affects carbonation of concrete. According to KS F 2563 blast furnace slag was classified 3 types. Type Ⅲ blast furnace slag(specific surface area is $4000cm^2/g$) from different providers with Type A, the B and the C. The statistical technique was applied to exclude error of engineering judgement. T test and F test were used among 3 groups to investigate statistical meaning. The effect which on the quality of blast furnace slag type Ⅲ that affects carbonation of concrete is significant.

It takes quite amount of time to study a board game because there are many game characters and many state spaces are exist for board games. Therefore, game must do learning long. But, there is weakness with reinforcement learning. On Learning early, the learning speed becomes slow. If there were equal result that both are considered to be best ones during the course of learning stage, Heuristic which utilizes learning of problem area of Jul-Gonu was used to improve the speed of learning. To compare a normal character to an improved one, a board game was created, and then they fought against each other. As a result, improved character's ability was improved on learning speed.

The objective of this study was to evaluate the effect of different ratios of horse meat and pork (horse meat: pork=0:100, 50:50, 100:0) on the quality and sensory characteristics of press hams. Press ham containing 100% horse meat had a higher moisture content (%) and lower fat content (%) than the other hams (p<0.05). The redness (hunter a value) and yellowness (hunter b value) were significantly higher in press ham containing 100% horse meat, whereas the lightness (hunter L value) was significantly lower than other hams (p<0.05). With regard to textural properties, press ham containing 100% horse meat had significantly higher springiness, but there were no significant differences among the ham products in regard to hardness, cohesiveness, gumminess and chewiness (p>0.05). The results of sensory tests showed that press ham containing 100% horse meat had significantly lower color and acceptability scores compared to other hams (p<0.05). With regard to mineral contents, Na, Fe, Mn, and Zn were significantly higher in press ham containing 100% horse meat (p<0.05).

This study examines the effects of in-company English programs on Korean employees' English learning. During the twelve weeks, 68 employees in Korea engaged in an English learning program in the workplace. Before and after the program, pre- and post-tests were conducted to see if their English proficiency improved. Pre- and post-surveys and interviews were also administered to understand how they perceived the program. Results show that the employees improved their English oral proficiency and their attitudes toward English learning positively changed, as a result of participating in the program. Also, the program appeared to be successful, meeting their needs. Given that little research has investigated the effects of in-company English learning, this study provides insights on the effectiveness of English programs in the workplace in Korea.

The welfare of horses depends on satisfying both the physiological and psychological needs of the animal. The object of this study was to evaluate fence safety at the horse farm. A Thoroughbred colt with cribbing was found dead in a paddock. The fence of paddock is a four-pipe fencing. He cribbed the 2nd pipe from the top. But he couldn't pull his face because his incisors acted as hooks and two ramuses of the mandible was entrapped in a top pipe. So he was embarrassed and went down while he terribly struggled to get out his face. Finally, he was strangulated to death. Safe fencing is essential on a horse farm. The function of these fences are to protect the horses but it was more of a hazard. In order to safe management of horses, facial length of the horse and the pipe interval of the fence should be considered. Further research is needed to put a muzzle on the horses while they are at a paddock. This study provides important benchmarks for the equine industry to consider fence type and evaluate fence safety.

Deonum preexisted prior to it being named. Of course, the object designated as deonum at that time is not the same as the object designated as deonum at this time. There have been historical transitions in the definitions of the term deonum. This paper traced the term deonum to its origin from another angle. On closer inspection about the possible use as the everyday language and the technical language in the field of arts except for pansori, the term deonum was essentially a word for a tune. Deonum was in the same category as deureum, a great word in the Korean traditional music. But the definition of deonum as a tune used in the early part of the former period of eight master singers or before that gradually disappeared for a long time. When the term deonum as an everyday language first entered the field of pansori, it meaned characteristic tune singed by master singers. As pansori develop artistically, the term deonum changed into the word refers to the sori part, and this example become common in the former period of eight master singers. Most sori part acknowledged as a deonum in the former period of eight master singers was a deonum as a creative repertories, the master singer's creative work, but a deonum as a popular repertories, the master singer's specialty, began to be acknowledged as a deonum after the latter period of eight master singers. The differentiation between the definitions of deonum as a sori part occured. And most sori part acknowledged as a deonum after the modern era of five master singers have belonged to a deonum as a specialty. In this context, it was confirmed that Cheong Nosik wrote Joseonchanggeuksa, with carefully considering the historical change of definitions of deonum. This book includes three definitions of deonum, a deonum as a tune, a deonum as a creative work, and deonum as a specialty.

This paper dealt with how realization of pauses in utterance is affected by speech style, gender, and generation. For this purpose, we analyzed the frequency and duration of pauses. Pauses were categorized into four types: pause with breath, pause with no breath, utterance medial pause, and utterance final pause. Forty-eight subjects living in Seoul were chosen from the Korean Standard Speech Database. All subjects engaged in reading and spontaneous speech, through which we could also compare the realization between the two speech styles. The results showed that utterance final pauses had longer durations than utterance medial pauses. It means that utterance final pause has a function that signals the end of an utterance to the audience. For difference between tasks, spontaneous speech had longer and more frequent pauses because of cognitive reasons. With regard to gender variables, women produced shorter and less frequent pauses. For male speakers, the duration of pauses with breath was significantly longer. Finally, for generation variable, older speakers produced more frequent pauses. In addition, the results showed several interaction effects. Male speakers produced longer pauses, but this gender effect was more prominent at the utterance final position.

Named Entity Recognition is a system that extracts entity names such as Persons(PS), Locations(LC), and Organizations(OG) that can have a unique meaning from a document and determines the categories of extracted entity names. Recently, Bi-LSTM-CRF, which is a combination of CRF using the transition probability between output data from LSTM-based Bi-LSTM model considering forward and backward directions of input data, showed excellent performance in the study of object name recognition using deep-learning, and it has a good performance on the efficient embedding vector creation by character and word unit and the model using CNN and LSTM. In this research, we describe the Bi-LSTM-CNN-CRF model that enhances the features of the Korean named entity recognition system and propose a method for constructing the traditional culture corpus. We also present the results of learning the constructed corpus with the feature augmentation model for the recognition of Korean object names.
