In this paper, we implemented a Korean text generation and classification model based on a deep learning algorithm that can be applied to various industries. It consists of two implemented GAN-based Korean handwriting generation models and CNN-based Korean handwriting classification models. The GAN model consists of a generator model for generating fake Korean handwriting data and a discriminator model for discriminating fake handwritten data. In the case of the CNN model, the model was trained using the 'PHD08' dataset, and the learning result was 92.45. It was confirmed that Korean handwriting was classified with % accuracy. As a result of evaluating the performance of the classification model by integrating the Korean cursive data generated through the implemented GAN model and the training dataset of the existing CNN model, it was confirmed that the classification performance was 96.86%, which was superior to the existing classification performance.

Recently, to accelerate the Ubiquitous generation, the input interface of the mobile machinery and tools are actively being researched. In addition with the existing interfaces such as the keyboard and curser (mouse), other subdivisions including the handwriting, voice, vision, and touch are under research for new interfaces. Especially in the case of small-sized mobile machinery and tools, there is a increasing need for an efficient input interface despite the small screens. This is because, additional installment of other devices are strictly limited due to its size. Previous studies on handwriting recognition have generally been based on either two-dimensional images or algorithms which identify handwritten data inserted through vectors. Futhermore, previous studies have only focused on how to enhance the accuracy of the handwriting recognition algorithms. However, a problem arisen is that when an actual handwriting is inserted, the user must select the classification of their characters (e.g Upper or lower case English, Hangul - Korean alphabet, numbers). To solve the given problem, the current study presents a system which distinguishes different languages by analyzing the form/shape of inserted handwritten characters. The proposed technique has treated the handwritten data as sets of vector units. By analyzing the correlation and directivity of each vector units, a more efficient language distinguishing system has been made possible.

본 논문에서는 은닉 마르코프 모형(HMM)을 이용하여 사람이 쓴 필기의 통계적 특징을 갖는 글씨를 생성하는 방법에 대해서 기술코자 한다. 온라인 필기처럼 같이 필기 궤적을 시계열 신호로 표현하고, 그 특징을 통계적 모형의 하나인 HMM으로 표현한다. HMM은 시계열 신호에 대응하는 모형 내부 경로와 심볼열의 확률 분포를 표현하는 함수이다. 따라서 최적 경로에서 볼 수 있는 최적 출력 심볼열은 훈련 필기 데이타의 평균적 필기 특징에 해당한다. HMM이 주어졌을 때 HMM에서 최적의 패턴을 해석적으로 구하는 방법은 알려져 있지 않다. 본 논문에서는 동적 프로그래밍 기법을 적용하여 HMM이나 HMM 네트워크 모형에서 필기를 생성하는 방법을 제시하고, 아울러 HMM의 문제점을 지적한다.

This study is to increase the utilization of the ozonated water generator to make it easier to take advantage of the ozone water in the world today, there will be to develop a system that operates in one motion. Furthermore, olive oil and ozone is reacted with the wish to apply to the manufacturing technology. In the case of many existing products ozone generator driven mostly non-ozone system. In the case of ozone, but handwriting is implied general way pressure ozone gas leakage risks of suction force to the pump, it is the case of the challenge by using the injector, and limit the generation of ozone and ozone inhalation according to whether the water inlet leakage of existing products risk due to minimized. Despite the disadvantages of the injector system was found the effectiveness of the ozonated water production unit injector system used in this study to maintain the microbiological disinfection performance.

Haenghaeng Ilgi (Diary of a Royal Trip) (koo 7152; hereafter Ilgi) in the collection of the National Museum of Korea provides an account of Crown Prince Sado's incognito royal visit to Pyeongyang in the fourth month of 1761. Ilgi was written by Ham Daeil, a low-ranking military officer in Pyeongyang. Ham was singled out for praise by Crown Prince Sado (1735-1762) and served the prince from the seventh day of the fourth month to the first day of the fifth month. Ilgi documented the deeds of Crown Prince Sado during this period and provides detailed information on his incognito visit to Pyeongyang, which was not officially recorded. Ilgi shows characteristics differentiating it from many other diaries. For example, the quality of the paper, neat handwriting, and well-organized sentences differ from those of common diaries. These distinctions indicate that Ilgi is closer to an official document than a private diary written by an individual. Since Ilgi records Crown Prince Sado's incognito visit to Pyeongyang, is only vaguely known otherwise, its contents need to be examined in terms of whether or not they are fully factual. As the first step in such verification, It is traced that Ham Daeil's family history which turned out to match what is written in Ilgi. Moreover, Ilgi mentions about Prince Crown Sado's writing a piece of calligraphy, and a matching piece of calligraphy written by Sado still survives today. It can be confirmed that the contents of Ilgi are factual in at least these regards. However, although Crown Prince Sado was known to have met people from various social classes during his visit to Pyeongyang, Ilgi focuses only on Crown Prince Sado and Ham Daeil. This suggests the possibility that the surviving version of Ilgi may be an edited condensation based on original texts containing more complete information on Crown Prince Sado's visit. Ilgi is presumed to have been produced during the generation of Ham Jeonghui, a son of Ham Daeil. The dates of birth and death of Ham Daeil fall during the reign of King Yeongjo. It is unlikely that any records regarding Crown Prince Sado would have been published while King Yeongjo, who was hostile to Sado, ruled the country. Ilgi also provides strong evidence that Ham Jeonghui presented the subsequent king, King Jeongjo, with the calligraphy by Crown Prince Sado and the diary. It is unclear if the book Ham Jeonghui presented him was the same as the extant version of Ilgi. Nonetheless, considering the situation at the time when King Jeongjo was pursuing several projects to honor his father Sado, it is highly probable that Ilgi was produced during the reign of King Jeongjo. The periods of presenting the calligraphy and the diary respectively overlapped with the production of Hyeollyungwon, the royal tomb of Crown Prince Sado, and Sado's sixtieth birthday. Therefore, is it considered reasonable that Ham Jeonghui produced Ilgi to promote his own social ambitions.
