더욱 사람같은 대화 모델을 실현하기 위해, 페르소나 메모리를 활용하여 응답을 생성하는 연구들이 활발히 진행되고 있다. 다수의 기존 연구들에서는 메모리로부터 관련된 페르소나를 찾기 위해 별도의 검색 모델을 이용한다. 그러나 이는 전체 시스템에 속도 저하를 일으키고 시스템을 무겁게 만드는 문제가 있다. 또한, 기존 연구들은 페르소나를 잘 반영해 응답하는 능력에만 초점을 두는데, 그 전에 페르소나 참조의 필요성 여부를 판별하는 능력이 선행되어야 한다. 따라서, 우리의 제안 모델은 검색 모델을 활용하지 않고 생성 모델의 내부적인 연산을 통해 페르소나 메모리의 참조가 필요한지를 판별한다. 참조가 필요하다고 판단한 경우에는 관련된 페르소나를 반영하여 응답하며, 그렇지 않은 경우에는 대화 컨텍스트에 집중하여 응답을 생성한다. 실험 결과를 통해 제안 모델이 장기적인 대화에서 효과적으로 동작함을 확인하였다.

Blenderbot 2.0 is a dialogue model representing open domain chatbots by reflecting real-time information and remembering user information for a long time through an internet search module and multi-session. Nevertheless, the model still has many improvements. Therefore, this paper analyzes the limitations and errors of BlenderBot 2.0 from three perspectives: model, data, and dialogue. From the data point of view, we point out errors that the guidelines provided to workers during the crowdsourcing process were not clear, and the process of refining hate speech in the collected data and verifying the accuracy of internet-based information was lacking. Finally, from the viewpoint of dialogue, nine types of problems found during conversation and their causes are thoroughly analyzed. Furthermore, practical improvement methods are proposed for each point of view, and we discuss several potential future research directions.

Personal service robots, a type of social robot that has emerged with the aging population and technological advancements, are undergoing a transformation centered around technologies that can extend independent living for older adults in their homes. For older adults to accept and use social robot innovations in their daily lives on a long-term basis, it is crucial to have a deeper understanding of user perspectives, contexts, and emotions. This research aims to comprehensively understand older adults by utilizing a mixed-method approach that integrates quantitative and qualitative data. Specifically, we employ the Van Kaam phenomenological methodology to group conversations into nine categories based on emotional cues and conversation participants as key variables, using voice conversation records between older adults and social robots. We then personalize the conversations based on frequency and weight, allowing for user segmentation. Additionally, we conduct profiling analysis using demographic data and health indicators obtained from pre-survey questionnaires. Furthermore, based on the analysis of conversations, we perform K-means cluster analysis to classify older adults into three groups and examine their respective characteristics. The proposed model in this study is expected to contribute to the growth of businesses related to understanding users and deriving insights by providing a methodology for segmenting older adult s, which is essential for the future provision of social robots with caregiving functions in everyday life.

오늘날 사회는 지식이 부가가치를 산출하는 지식기반사회로, 이러한 지식은 전통적인 교과적 지식과는 달리 신속성, 다양성, 복잡성을 가진 특성을 가지고 있으며, 생산, 저장, 공유 및 재생산의 과정을 거쳐가면서 가치를 더해 가는 것이다. 사회현장의 이러한 변화에 따라 인력을 양성하는 대학에서도 대학경영으로 변화할 것을 요구하고 있다. 즉, 대학은 기존 체제와 운영방식을 유지하는 것보다도, 팀 중심으로 기존의 지식을 공유하고 대화와 토론을 중시하는 학습조직화를 통하여 새로운 대학체제를 창조하는 지식경영적 접근이 요구된다. 이를 위해서 대학은 지역과 구성원의 특성을 살리면서도 미래의 변화에 부응하는 장기적인 통찰과 정책이 필요하다.

Recently, the number of elderly people residing in nursing homes has increased rapidly due to the increase in the elderly population and the introduction of long-term care insurance. These long-term care patients suffer from chronic illnesses and dementia, and thus suffer from inconveniences or lack of cognitive ability. Thus, psychological and emotional support is urgent because they are depressed away from their families. Therefore, in this paper, we aim to provide a virtual experience of overseas trips by using VR and Photon networks for elderly patients with mobility difficulties. Existing VR-based travel experience service is doing alone, but the proposed contents can enjoy the scenery together with the view of the family member as well as the conversation during the travel experience. It is expected that the elderly patients with long - term care will be able to restore their psychological stability and improve their willingness to heal and improve their quality of life from the proposed application.

People with mental illness are generally either unaware of their illness or unwilling to voluntarily seek treatment, which makes treatment difficult and the pain mainly passed on to their families. Accordingly, non-face-to-face treatment, in which the patient is diagnosed by interviews with the family and unannounced medication, in which medication is secretly administered through the family, can be performed, and this has been considered a necessary evil. Even considering realistic aspects such as the special nature of mental health care and families' suffer, not-informed treatment without consent violates not only medical laws, but also human rights of mentally ill patients. Above all, if the patient finds out about this late, the trust between the patient, family, and doctor is completely broken, and a treatment is absolutely refused. Japan's Chiba decision, which presents exceptional conditions for allowance might be a solution. However, it would not be a right solution, considering that it could lead to long-term unannounced medication and completely cut off treatment through therapeutic dialogue. Ultimately, it need to approach this problem and seek alternatives through restoration of therapeutic dialogue.

이 글은 1959년 도미 이후 현재까지 10여년간 미국에 체재하면서 미국 도서관계에서 많은 활약을 하고 계신 우리나라의 유일한 도서관학 박사이신 김중한 박사께서 지난 5월 국제회의에 참석차 잠시 귀국하여 고국의 관계를 보고 돌아 가신 후 고국의 도서관계가 보다 더 바람직한 내일이 건설되기를 염원하는 뜻으로 집필해 주신 글이다. 다만 현실적으로 아직 실현 시키기에 어려운 것도 없지 않다. 그러나 근대화의 걸음을 재촉하여 총력적인 작업을 추진하고 있는 우리 나라가 급진적으로 사회현상이 발전해 가고 전문화되어 감에 따라 사회가 도서관에 대한 인식이 성열되고 보다 더 적극적인 요구가 부원간 도래할 것이라고 하는 신념을 갖고 있는 우리들에게 새로운 진로가 될 수 있는 좋은 제언이라고 생각한다. 따라서 이 글이 팔자인 김박사께서도 서두에서 밝힌 바와 같이 한국의 도서관 발전 장기계획을 수립하는 데 있어서 대화의 테마와 한 아이디어로 제시하고 있는 만큼 충분하고 객관적인 분석 비판 검토와 연구가 있어야 할 것으로 믿으며, 항상 고국의 관계 발전과 성장을 위해 염려와 격려를 아끼지 않으시는 필자에게 애심으로 감사를 드리는 바이다.

A real time interactive controller (spectrometer) for magnetic resonance imaging (MRI) system has been developed using high speed digital signal processors (DSP). The controller generates radio frequency (rf) waveforms and audio frequency gradient waveforms and controls multiple receivers for data acquisition. By employing DSPs having high computational power (e.g., TMS320C670l) real time generation of complicated gradient waveforms and interactive control of selection planes are possible, which are important features in real-time imaging of moving organs, e.g., cardiac imaging. The spectrometer was successfully implemented at a 1.5 Tesla whole body MRI system for clinical application. Performance of the spectrometer is verified by various experiments including high- speed imaging such as fast spin echo (FSE) and echo planar imaging (EPI). These high-speed imaging techniques reduce measurement time, however, usually intensify artifact if there is any systematic phase error or jitter in the synchronization between the transmitter, receiver, and gradients.

The purpose of this study is to analyze the roles and functions of NGO 's International Solidarity in the establishment of' DMZ World Peace Park ', the mechanism of operation, and the policy formation of NGO' s international solidarity. The establishment of the DMZ World Peace Park is a matter that can be achieved as a result of dialogue efforts between the two parties based on the agreement between the DPRK and the ROK government, but should take a more relaxed approach to the process issues in order to achieve such results And should be done in a long-term, step-by-step plan. In the process of realizing this, South Korea's own efforts alone are difficult, and it is necessary to seek various channels of dialogue with the international community so that North Korea can have dialogue negotiations. This will be the role of NGO, It should be noted. As a result, in order to establish 'DMZ World Peace Park', it is necessary to establish concrete road map of DMZ World Peace Park. In the first stage, it is necessary to organize and operate 'DMZ World Peace Park Promotion Committee' under the directorship of the President or Prime Minister, It is necessary to select candidates, to appeal to North Korea and to support the international community, and to participate voluntarily by the private sector. Phase 2 requires final settlement. Phase 3 will require a step-by-step road map, such as rapid construction of the Peace Park, expansion of peaceful use of the DMZ, and expansion of ecology, history and cultural tourism in the DMZ border area.
