This paper tries to explore the local uniqueness and evolutionary characteristics of the spatial structure of the rural dwelling houses of China's Korean Ethnic. For this purpose, the paper selected 51 typical samples in each district, analyzing their ancestral home, building age, size, construction method, family composition etc. Moreover, the paper classified the pattern of the samples and analyzed the characteristic and evolutionary process of each pattern. Conclusions based on the analysis of the ancestral homes are as follows: 1.The house pattern of these China's Korean ethnics who are originally from the Hamkyung province is mainly jeongji- access type (A-type). A-type is mainly distributed along the Tumen River and Yalu River, in the Sino-Russian borders and the inland areas of Heilongjiang province. With the migration of the China's Korean ethnics, in Sino-Russian borders and the inland areas of Heilongjiang province, A-type with the 'badang' space, vestibule-access type (C-type) and living-centered type (D-type) appeared. 2. House patterns of Korean ethnics who are originally from the Pyongan province include three types: A-type, kitchen type (B-type) and C-type. A-type is mainly distributed along the Yalu River while B-type and C-type are mainly in the inland areas of these three Northeast provinces. With the decrease of population, the merger of rooms happened in A-type; while in the B-type and C-type, bathroom and storage came to exist in the north of the room. 3. The house pattern of Korean ethnics who are originally from the Gyeongsang province is mainly B-type, which is distributed in the inland areas of Heilongjiang and Jilin provinces. Besides, C-type and D-type also exist. They are in Jilin and Liaoning provinces. In the process of evolution, storage was set in the north part of the room or the window was cancelled in order to defend the coldness in Heilongjiang area, while in Jilin and Liaoning provinces, living room came into existence, which is gradually developing to D-type.

In this paper, a NeuroFuzzy controller (NFC) with enhanced packet reservation multiple access (PRMA) protocol for QoS-guaranteed multimedia communication systems is proposed. The enhanced PRMA protocol adopts mini-slot technique for reducing contention cost, and these minislot are futher partitioned into multiple MAC regions for access requests coming from users with their respective QoS (quality-of-service) requirements. And NFC is designed to properly determine the MAC regions and access probability for enhancing the PRMA efficiency under QoS constraint. It mainly contains voice traffic estimator including the slot information estimator with recurrent neural networks (RNNs) using real-time recurrent learning (RTRL), and fuzzy logic controller with Mandani- and Sugeno-type of fuzzy rules. Simulation results show that the enhanced PRMA protocol with NFC can guarantee QoS requirements for all traffic loads and further achieves higher system utilization and less non real-time packet delay, compared to previously studied PRMA, IPRMA, SIR, HAR, and F2RAC.

Objectives: This study reviewed the status of adverse event (AE) reporting in VigiAccess using anti-obesity agents as examples and explored the possibility of its use and future challenges. Methods: AE reports related to some representative drugs among herbal medicines (HMs), complex HM prescriptions, ingredients of supplements, and over-the-counter and prescription medicines were investigated using VigiAccess on February 1, 2024. Results: AE reports on prescription drugs were overwhelmingly higher than those on HMs or supplements. Although most reports were submitted from North America, reports on Ephedra sinica and green tea extract (GTE) were more from Asia and Europe, respectively. The female population reported more, and the difference in the sex ratio was the smallest for Ephedra spp. The age group was concentrated on young adults, but many older patients reported GLP-1 receptor agonist-related AEs. Symptoms related to the gastrointestinal and nervous systems were most commonly reported, but mental and cardiac disorders were common in Ephedra-type HMs. Hepatobiliary disorders are also commonly found in GTE-related reports. Conclusions: VigiAccess was useful for easily checking the global status of AE reporting for prescription drugs. However, several limitations were observed in using VigiAccess for HMs because of the few reports. Thus, it is necessary to increase the number of reports by education and to promote AE reporting among HM prescribers and users. The full range of HMs should be included in the pharmacovigilance system, and the coding and classification of HMs should be revised.

As the elderly population are rapidly growing, the elderly who needs special care and nursing homes for them are also growing. However, many nursing homes were planned without considering the hierarchial space organization such as division of housing unit and nursing unit based on the cognitive and behavioral characteristics of the elderly or accessibility and supportiveness of the staff. This study was to examine the hierarchial characteristics in space organization of nursing homes by using Space Syntax. The subjects were 8 nursing homes in Busan. First, spaces in nursing homes were divided into five areas based on the literature review. Then the hierarchy of space organization for the access layer and layers of living floors was grasped by using G-graph. The access layer has a tree-type hierarchical structure and high visuality. Also, average depth of the space was 5. Then the full integration was analyzed. Mobile area, such as elevator, hallways, or living rooms has a high accessibility and the middle corridor type has commonly been characterized. The nursing stations were analyzed through the control degree and it was low in three nursing homes such as B, C, and G. The low clarity was showed in B, D, and F. The low clarity means that it is relatively difficult to recognize the whole space organization of nursing home. Even though the hierarchy of their living floors was tree-type structure with a high visuality, they has a type of grouping spaces around hallways and spreading, or a ring type.
