In this paper, we propose a face hallucination method based on example-learning. The traditional approach based on example-learning requires alignment of face images. In the proposed method, facial images are segmented into patches and the weights are computed to represent input low resolution facial images into weighted sum of low resolution example images. High resolution facial images are hallucinated by combining the weight vectors with the corresponding high resolution patches in the training set. Experimental results show that the proposed method produces more reliable results of face hallucination than the ones by the traditional approach based on example-learning.

Recently, the rising demand for intelligent video surveillance system leads to high-performance face recognition systems. The solution for low-resolution images acquired by a long-distance camera is required to overcome the distance limits of the existing face recognition systems. For that reason, this paper proposes a hardware design of an image resolution enhancement algorithm for real-time intelligent video surveillance systems. The algorithm is synthesizing a high-resolution face image from an input low-resolution image, with the help of a large collection of other high-resolution face images, called training set. When we checked the performance of the algorithm at 32bit RISC micro-processor, the entire operation took about 25 sec, which is inappropriate for real-time target applications. Based on the result, we implemented the hardware module and verified it using Xilinx Virtex-4 and ARM9-based embedded processor(S3C2440A). The designed hardware can complete the whole operation within 33 msec, so it can deal with 30 frames per second. We expect that the proposed hardware could be one of the solutions not only for real-time processing at the embedded environment, but also for an easy integration with existing face recognition system.

Jeon-Kwang(癲狂) is a term of oriental medicine, corresponding to schizophrenia. In detail, Jeon-Kwang is divided into Jeon(癲) and Kwang(狂). The symptoms of Jeon have silence, cry and giggle alternately, muttering, and so on. And those of Kwang have quick-tempered, absurd remarks, slander, and so on. We expierenced a patient who was suffered from headache, auditory hallucination, insomnia, anxiety, delirium, memory impairment and, cognitive disorder. In this case, we gave a diagnosis of Jeon-Kwang(狂) and, treated the patient with acupuncture therapy and sa-ha(瀉下) therapy (Dangguiseunggi-tang, Hwangryunsasim-tang). Sa-ha therapy is an oriental medicine therapy about wha(火) syndrom such as constipation, hydrodipsomania, red face. After three weeks of oriental medicine treatment, the chief complaints were considerablely reduced. This suggested that sa-ha herbal treatment have an effect on psychopathy.

This study is a qualitative study to explore the experiences of nursing students' psychological nursing practice in-school. The subjects of this study were 62 students who were the 3rd grade nursing students at a University in Gangwon-do. The data were collected from August 3rd to August 20th, 2020. For data analysis, Colaizzi's qualitative analysis method was applied. Six categories were derived from data analysis: 1) Lingering affection for clinical practice in field. 2) Achievement through learning 3) Fear of nurse's role in future 4) Burden for many tasks 5) Feeling free of stress from clinical practice in field 6) Importance of cooperation with other departments. The positive aspects of in-school practice education, which from nursing students' evaluation, were immediate feedback, detailed explanations, and indirect experiences. Based on this study result, it is recommended to develop in-school nursing practice education program for gap-reducing with clinical practice. It would be consisted of various contents: simulation, online/non-face-to-face practice, face-to-face practice for indirect experience. In addition, these multi-aspect effort is needed more in psychological nursing practice education to reduce the gap with clinical practice such as therapeutic communication and hallucination interventions.

The Korean government ranked 3rd among 193 UN member countries in the UN's 2022 e-Government Development Index. Korea, which has consistently been evaluated as a top country, can clearly be said to be a leading country in the world of e-government. The lubricant of e-government is data. Data itself is neither information nor a record, but it is a source of information and records and a resource of knowledge. Since administrative actions through electronic systems have become widespread, the production and technology of data-based records have naturally expanded and evolved. Technology may seem value-neutral, but in fact, technology itself reflects a specific worldview. The digital order of new technologies, armed with hyper-connectivity and super-intelligence, not only has a profound influence on traditional power structures, but also has an a similar influence on existing information and knowledge transmission media. Moreover, new technologies and media, including data-based generative artificial intelligence, are by far the hot topic. It can be seen that the all-round growth and spread of digital technology has led to the augmentation of human capabilities and the outsourcing of thinking. This also involves a variety of problems, ranging from deep fakes and other fake images, auto profiling, AI lies hallucination that creates them as if they were real, and copyright infringement of machine learning data. Moreover, radical connectivity capabilities enable the instantaneous sharing of vast amounts of data and rely on the technological unconscious to generate actions without awareness. Another irony of the digital world and online network, which is based on immaterial distribution and logical existence, is that access and contact can only be made through physical tools. Digital information is a logical object, but digital resources cannot be read or utilized without some type of device to relay it. In that respect, machines in today's technological society have gone beyond the level of simple assistance, and there are points at which it is difficult to say that the entry of machines into human society is a natural change pattern due to advanced technological development. This is because perspectives on machines will change over time. Important is the social and cultural implications of changes in the way records are produced as a result of communication and actions through machines. Even in the archive field, what problems will a data-based archive society face due to technological changes toward a hyper-intelligence and hyper-connected society, and who will prove the continuous activity of records and data and what will be the main drivers of media change? It is time to research whether this will happen. This study began with the need to recognize that archives are not only records that are the result of actions, but also data as strategic assets. Through this, author considered how to expand traditional boundaries and achieves reterritorialization in a data-driven society.
