重庆邮电大学学报（自然科学版） 2007年第3期19卷 339-346页

作者： Seung-Ryun Lee Dae-Ho Bae soon ju Kang School of Electrical Engineering and Computer Science Kyungpook National University

Existing home devices in home network provides only independent services limited on a homogeneous protocol and/or do not fully support an intelligent service provided by cooperating among heterogeneous protocol devices. This paper proposes an intelligent and integrated service binding architecture which allow the users to figure out the status of devices and to cooperate among home network devices regardless of supported protocols or operational characteristics.

A Study on Simple Prediction Method of Heat Load： A Use of Linear Approximation Indicial Response in Basements

引用

Journal of Civil Engineering and Architecture 2013年第4期7卷 379-387页

作者： Kyung-soon park Hiroaki Kitano Hisaya Nagai Department of Building Systems Engineering Dong-Eui University Busan 614-714 Korea Department of Architecture Graduate School of Engineering Mie University Tsu 514-8507 Japan

This study was conducted to establish a predictable method for a heat load of an underground structure with sufficient accuracy. As the first step, our previous paper reported the measurement results of field experiments on an underground experimental basement under internal heat generation conditions. Also, it presented the results of numerical analyses on the heat and moisture behavior and the influence of internal heat generation of the experimental basement and ground. However, it is practically impossible to utilize the model of simultaneous heat and moisture transfer at the design phase because the prediction by the model of simultaneous heat and moisture transfer requires a long calculation time. In this paper, the authors present the simple load calculation technique, using a linearized approximation indicial response of the inner surface heat flux in a basement to outdoor air temperature change. In addition, the approximation indicial responses for each part of the single-walled concrete drawn using this technique are arranged. The heat load calculation example of application to the basement of the optional size by this technique is shown.

Factors Affecting Maternal Coping in Korean Mothers of Children with Cancer

引用

Open Journal of Nursing 2016年第9期6卷 751-766页

作者： Shanzida Khatun Hee soon Kim Hyun-Bong park College of Nursing Yonsei University Seoul South Korea Mo-Im Kim Nursing Research Institute Seoul South Korea

Background: The childhood cancer is increasing throughout the world. The incidence of children and adolescent (1 - 19 years old) mortality by cancer was 4.49 by 2006 (Korea Statistics, 2014). Mothers of children experienced a difficult situation in coping when their children were diagnosed with cancer. Based on Mishel’s Uncertainty in Illness Theory, maternal uncertainty and perceived social support are important factors that may have an impact on maternal coping in mothers of children with cancer. Therefore, it was worth to investigate this phenomenon in the context of Korea where no such study was conducted. Objective: To identify the factors affecting maternal coping in mothers of children with cancer. Methods: The study was conducted by using a descriptive design. This study was approved by the Institutional Review Board, Yonsei Health System, Severance Hospital, Seoul, Korea and informed consent forms were obtained from the participants. Fifty-nine mothers completed three questionnaires: 1) Parent’s Perception of Uncertainty Scale, 2) Multidimensional Scale of Perceived Social Support, and 3) Coping Health Inventory for Parents. The internal consistency of these instruments was satisfactory, all with alpha coefficients over 0.86. Results: Hierarchical multiple regression analysis revealed that perceived social support and maternal uncertainty together explained 35% of the variance in the maternal coping in mothers of children with cancer (R2 = 0.353, F = 15.255, p = 0.000). Perceived social support and maternal uncertainty had an impact on maternal coping. Conclusions: The findings provided information that could be used in a further intervention study to increase maternal coping in mothers of children with cancer.

Low-Power High-Efficiency Multi-Gigabit 60 GHz Fransceiver Systems Routing in Vehicular Environments

引用

ZTE Communications 2016年第B12期14卷 20-24页

作者： Chul Woo Byeon Chul soon park Department of Electronic Engineering Wonkwang University Iksan 54538 Korea Department of Electrical Engineering KAIST Daejeon 305-701 Korea

This paper proposes low-power high-efficiency multi-gigabit 60 GHz transceiver systems for short-range communications. 60 GHz muhi-gigabit on-off keying （OOK） receiver system-in-package （SIP） module is developed using a low temperature co-fired ceramic （LTCC） technology. Integrated with a low-power complementary metal oxide semiconductor （CMOS） OOK demodulator, the LTCC receiver module demonstrates Full-HD uncompressed video streaming at a distance of 1 m. A low-power and high-efficiency fully integrated OOK transceiver is also developed to be integrated in a handheld device. The transceiver consumes 67 mW at 10.7 Gb/ s and occupies an active footprint of 0.44 mm^2. With an on-board Yagi-Uda antenna, the transceiver achieves 10.7 Gb/s of data transmission, resulting in a high energy efficiency of 6.26 pJ/bit. The antenna-in-package module with the transceiver demon- strates mobile-to-display 1080p Full-HD video transmission over a distance of 60 cm.

Neural Regeneration Research 2010年第3期5卷 226-231页

作者： Mi-Hyun Choi Su-Jeong Lee Jae-Woong Yang Jin-Seung Choi Hyung-Sik Kim Jeong-Han Yi Gye-Rae Tack soon-Cheol Chung Byung-Chan Min Se-Jin park Jong-Rak park Jae-Hoon jun Department of Biomedical Engineering Research Institute of Biomedical Engineering College of Biomedical & Health Science Konkuk University Department of Industrial & Management Engineering Hanbat National University Division of Technology Services National Center for Standard Reference Data Korea Research Institute of Standards and Science Department of Photonic Engineering Chosun University

BACKGROUND： Previous studies have analyzed cerebral activation and lateralization of cognitive functions, as well as cerebellar function with reference to high-level cognitive processing. However, there has been very little research on systematization and diversification. In particular, there are no reports on cerebellar lateralization, although reliable results have been reported on cerebral lateralization. OBJECTIVE： This study analyzed cerebellar activation and lateralization in relation to verbal and visuospatial tasks using functional magnetic resonance imaging （fMRI）. DESIGN, TIME AND SETTING： A block design for fMRI observation was performed at the fMRI Laboratory, Brain Science Research Center, Korea Advanced Institute of Science and Technology from May 2006 to September 2008. PARTICIPANTS： Sixteen healthy, male, college students, aged （23.3 ± 0.5） years, and 16 healthy, male, college students, aged （21.5 ± 2.3） years, participated in the study, respectively. METHODS： Verbal and visuospatial tasks were presented while functional brain images were acquired using a 3T fMRI system. Verbal analogy testing required the subject to select the word with the same relationship as one of the given words. Verbal antonym testing required the subject to select the word with a different meaning among four words. Visuospatial tasks involved selecting a shape that corresponded to a given figure with four examples, as well as selecting a development figure of a diagram. MAIN OUTCOME MEASURES： Changes in cerebellar activation and lateralization between two cognition tasks. RESULTS： Bilateral hemisphere Iobules VI and IX, right hemisphere Iobule VIII, bilateral hemisphere Iobules Crus I, and vermis Iobule IV, V, and Vl were closely related to verbal tasks in comparison to visuospatial tasks. Conversely, bilateral hemisphere Iobules IV and V, as well as the right hemisphere Iobule VI, were closely related to visuospatial tasks compared to verbal tasks. There was no great differe
