이 글은 기존의 하이틴 관련 연구들이 누락하고 있는 물음인 '하이틴이란 대체 무엇인가'를 고찰한다. 하이틴은 전후 범 동아시아 팝 문화 씬 권역 중 일본과 한국에서만 통용된 일본발 외래신어이다. 전후 미국에서 형성된 '틴에이저' 문화와 맥을 같이 하는 하이틴은 단순히 대중문화의 하위 카테고리가 아니라 전후 일본 정치의 중요한 이데올로기적 알레고리로 이해돼야 한다. 이를 알아보기 위해 우선, 개념으로서 하이틴이 의미화된 초기의 사례를 고고학적으로 추적한다. 그리고 이를 바탕으로 일본의 전후 정치·이데올로기와 맞물리며 형성된 하이틴의 표상-이미지로서 우에다 히라오의 초기 하이틴물의 정치적 의미를 살펴본다. 그간의 하이틴 연구가 한국이라는 지엽적이고 단편적인 영역에 한정되었던 데 반해, 이 글은 전후 동아시아사라는 보다 보편적인 지평에서 '하이틴'을 논의하는 단초가 될 것이다.

본 논문은, 개인 간 거래 C2C에 기반으로 해외직구 불법 거래에 관한 모니터링 시스템을 제안한다. 관세법에서는 해외직구 물품이 일정 금액 (미화 150불, 단 미국은 미화 200불)이하 또는 자가 사용 물품으로 인정되는 경우에만 제세를 면제토록 규정하고 있다. 과세를 면제받아 구매한 해외직구 물품을 온라인 등에서 되파는 행위는 무신고 밀수입죄에 해당한다. 그런데도 온라인 중고 사이트에는 이에 대한 되팔이가 증가하여 지속적인 관세법 위반이라는 사회적 이슈로 논란이 되고 있다. 따라서 본 연구에서는 해외직구 관련 불특정 거래 내용을 수집하고, 정보를 빅데이터 방식으로 데이터를 정제하여, 자연어 처리 등을 통해 모니터링 시스템으로 설계하여 판매자와 유사한 형태를 보이는 키워드 분석, 거래방식 분석, 동일성 판별 등을 분석하였다. 해외직구 물품의 불법 거래 단속에 활용이 가능할 것이다.

In most self-center braces, decreasing residual deformation is possible only by increasing pretension force, which results in lower energy dissipation capacity. On the other hand, increasing energy dissipation capacity means higher values of residual deformation. The goal of this research was to find the best design for a self-centering buckling restrained brace (SC-BRB) system by balancing self-centering capability and energy dissipation. Three, six, and nine-story structures were investigated using OpenSees software and the TCL programming language to achieve this goal. For each height, 62 different SC-BRBs were considered using different values for the pretension force of cables, the area of the buckling restrained brace (BRB) core plate, and the yield stress of the core plate. The residual deformation and dissipated energy of all the models were calculated using nonlinear analyses after cyclic loading was applied. The optimum design for each height was determined among all the models and was compared to the structure equipped with the usual BRB. The residual deformation of the framed buildings was significantly reduced, according to the findings. Also the reduction of the energy dissipation was acceptable. The optimum design of SC-BRB in 6-story building has the most reduction percent in residual deformation, it can reduce residual deformation of building 83% while causing only a 57% of reduction in dissipated energy. The greatest reduction in residual deformation versus dissipated energy reduction was for the optimum SC-BRB design of 9-story building, results indicated that it can reduce residual deformation of building 69% while causing only a 42% of reduction in dissipated energy.

Igbo, a new Benue Congo language has a vowel harmony system which, like that of Akan, is based on the pharynx size or tongue root position. In this study we examine Igbo vowel harmony with particular reference to assimilatory patterns of vowels in different harmony sets. This is to gain some insight into the factors involved in Igbo vowel assimilation, and to establish to what extent reports on Akan vowel assimilation are validated in Igbo. Tokens of the eight phonemic vowels of Standard Igbo are recorded from three native speakers of Igbo. The vowels are acoustically investigated (using the LPC analysis of CSL) in individual lexical items and within carefully designed carrier phrases. The F1 and F2 values of the vowels are obtained as these formant values are generally useful in establishing the salient characteristics of vowels. Vowels from the harmony sets are juxtaposed in the carrier phrases to ascertain the extent of assimilation. Results of the investigation show that the F1 values, to a large extend, are enough to characterize these vowels. The (-Expanded) vowels have higher F1 values than their (+Expanded) counterpart. Where there is an overlap in F1 values for some vowels the F1 bandwidth values serve to distinguish between the vowels. The overlap often reported in Akan for /I/ and /e/ on the one hand and /${\mho}$/ and /o/ on the other is not validated in Igbo. While the F1 values for these pairs of vowels are quite similar for one of our speakers, there is an appreciable difference between the F1 values of these vowels for the other two speakers. There is however an overlap for /e/ and /o/ for one of the speakers. Assimilations are generally regressive across word boundaries. It is, however, necessary to point out that the general perceptual impression that one of the vowels completely assimilates to the other, is not borne out by our investigation. Most of our F1 and F2 values for the vowels in individual lexical items are altered in assimilations. This then suggests that assimilation involving these vowels is partial rather than complete. The emerging 'allophones' are acoustically similar to the (+Expanded) vowel involved in the assimilation, that is when vowels from different harmony sets are involved. We conclude that while assimilation of Igbo vowels involves some phonological considerations, phonetic factors appear to be permanent in deciding the final form of the vowels.

In this study, we explored the potential of integrating interactive AI callbot technology into the medical consultation domain as part of a broader service development initiative. Aimed at enhancing patient satisfaction, the AI callbot was designed to efficiently address queries from hospitals' primary users, especially the elderly and those using phone services. By incorporating an AI-driven callbot into the hospital's customer service center, routine tasks such as appointment modifications and cancellations were efficiently managed by the AI Callbot Agent. On the other hand, tasks requiring more detailed attention or specialization were addressed by Human Agents, ensuring a balanced and collaborative approach. The deep learning model for voice recognition for this study was based on the Transformer model and fine-tuned to fit the medical field using a pre-trained model. Existing recording files were converted into learning data to perform SSL(self-supervised learning) Model was implemented. The ANN (Artificial neural network) neural network model was used to analyze voice signals and interpret them as text, and after actual application, the intent was enriched through reinforcement learning to continuously improve accuracy. In the case of TTS(Text To Speech), the Transformer model was applied to Text Analysis, Acoustic model, and Vocoder, and Google's Natural Language API was applied to recognize intent. As the research progresses, there are challenges to solve, such as interconnection issues between various EMR providers, problems with doctor's time slots, problems with two or more hospital appointments, and problems with patient use. However, there are specialized problems that are easy to make reservations. Implementation of the callbot service in hospitals appears to be applicable immediately.

In this era of information and communication technology (ICT), tremendous improvements have been witnessed in our daily lives. The impact of these technologies is subjective and negative or positive. For instance, ICT has brought a lot of ease and versatility in our lifestyles, on the other hand, its excessive use brings around issues related to physical and mental health etc. In this study, we are bridging these both aspects by proposing the idea of AI based mental healthcare (AIMS). In this regard, we aim to provide a platform where the patient can register to the system and take consultancy by providing their assessment by means of a chatbot. The chatbot will send the gathered information to the machine learning block. The machine learning model is already trained and predicts whether the patient needs a treatment by classifying him/her based on the assessment. This information is provided to the mental health practitioner (doctor, psychologist, psychiatrist, or therapist) as clinical decision support. Eventually, the practitioner will provide his/her suggestions to the patient via the proposed system. Additionally, the proposed system prioritizes care, support, privacy, and patient autonomy, all while using a friendly chatbot interface. By using technology like natural language processing and machine learning, the system can predict a patient's condition and recommend the right professional for further help, including in-person appointments if necessary. This not only raises awareness about mental health but also makes it easier for patients to start therapy.

Purpose: This research delves into the various factors that influence the performance of restaurant businesses on social commerce platforms in Bangkok, Thailand. The study considers both internal and external factors, including but not limited to business characteristics and location. Moreover, this research also analyzes the effects of employing multiple social commerce platforms on business efficiency and explores the underlying reasons for such effects. Research design, data, and methodology: Restaurants can be classified into different price ranges: low, medium, and high. To further investigate, we employed natural language processing AI to analyze online reviews and evaluate algorithm performance using machine learning techniques. We aimed to develop a model to gauge customer satisfaction with restaurants across different price categories effectively. Results: According to the research findings, several factors significantly impact restaurant groups in the low and mid-price ranges. Among these factors are population density and the number of seats at the restaurant. On the other hand, in the mid-and high-price ranges, the price levels of the food and drinks offered by the restaurant play a crucial role in determining customer satisfaction. Furthermore, the correlation between different social commerce platforms can significantly affect the business performance of high-price range restaurant groups. Finally, the level of online review sentiment has been found to influence customer decision-making across all restaurant types significantly. Conclusions: The study emphasizes that restaurants' characteristics based on their price level differ significantly, and social commerce platforms have the potential to affect one another. It is worth noting that the sentiment expressed in online reviews has a more significant impact on customer decision-making than any other factor, regardless of the type of restaurant in question.

A nation's culture isn't consisted by the characteristics of the nation only, but it is greatly affected by the geographical features and natural conditions, and it could be also dominated by the continual effect through mutual contact on economic exchange or social problem and political interests with neighboring countries. It is a well known fact that the contact of culture between Korea and Mongolia established under the special political situation that Corea was invaded by Won. But more basically, the Nomad including Mongolia had influenced upon neighboring countries, therefore, our country was also greatly influenced on consisting of our own culture by them. Moreover. the fact that our language belongs to their language's category(mostly Tweigru and Mongolian language) proves that the origin of our culture was deeply related with Mongolia. Accordingly, we could not limit the cultural relation between Korea and Mongolia within a special era. But especially, since unification of China by Mongolia, Won which appeared as a new great nation had dominated Corea for one hundred years, and the Corea's costume culture had a point of conversion to the mongolian. Therefore, this study expects to comment upon the relations of costume between Corea and Mongolia from a view point of Corea's tribute and royal gifts gifts by Mongolia written on the reference literatures. 1) From the ancient times, between our country and Mongolia there has been a direct or indirect exchange caused by the people's movement or invasion due to very closed neighboring. The relations between Corea and Mongolia have started from the mongolia's requests of tribute for the reason why they helped Corea against the Keoran's invasion, and these relation had continued by King Kongmin's age. 2) Mongolia had plundered a tribute such as dress, cereals, horses, military supplies, soldiers, maiden and little girls etc. from Corea, and therefore, a great confusion occurred on political, economic and social fields. And since King Chungyoul of Corea got married with a Princess of Won, the Corea's position was placed as the Buma nation(nation of son in law) and then high class people of Corea preferred to follow the mongolian costume such as Byunbal (pigtail), Ho dress (mongolian dress), Rouges, Chockturi (a kind of formal cap) and Doturak pigtail ribbon, and some have been applied up to date. On the other hand, the custom of Corea had transmitted to the Mongolian nobility, they called it "Corea Yang(style)". 3) The costume of Corea could be divided into three different periods, the first is the period influenced by Tang and Song's regime, the second is affected by the Won's costume and the third is applying the Myung's regime in the end of Corea. The Mongolian dress was based on the Ho dress form and it has been developed through compounding artistic traditional fields and foreign customs in long history. And Mongolia is composed of various tribes, therefore, they have their own dress for each tribe. Our country and Mongolia had a similar dress form based on Ho dress and both used the Chacksukunggo (jacket with small sleeves and slacks) and Seon(line). And the ornaments of costume such as Chockturi, Doturak pigtail ribbon and Rouges had transmitted and fixed down as a traditional wedding garment, but the Rouges has been used by noble women from the ancient times in our country. Since a member of the Society of Korean Costume has visited Mongolia in August 1990 for the first time, I really recognized the neccesity of more detailed study on the costume relation between Korea and Mongolia, and I will proceed with the study on various fields of costume under cooperation of Institute of Oriental Academy of Mongolia.
