Purpose: The purpose of this study is to provide data on the basis for architectural planning of floor plan type and spatial composition by analysing standard mental health centers in Seoul. Methods: Data were collected through literature research, field surveys, and expert interviews to 22 standard mental health centers in Seoul. Results: The results of this study could be summarized as follows; Firstly, Mental Health Center is divided into five types according to the location. Location types of mental health center were 'Director type', 'Health center connection type', 'Public facilities connection type', 'Complex center connection type' and 'Commercial Facilities connection type'. Secondly, Depending on the type of management a mental health center is divided into two types. Types are 'Complex type' and 'Independent type'. Average area of 'Complex type' is $192.99m^2$ and 'Independent type' is $266.87m^2$. This difference affects the various spaces. Implications: It is necessary to give and architectural suggestion of mental health center in response to the proposal of the system.

A hardware-acceleration architecture that separates virtual network functions (VNFs) and network control (called HSN) is proposed to solve the mismatch between the simple flow steering requirements and strong packet processing abilities of software-defined networking (SDN) forwarding elements (FEs) in SDN/network function virtualization (NFV) architecture, while improving the efficiency of NFV infrastructure and the performance of network-intensive functions. HSN makes full use of FEs and accelerates VNFs through two mechanisms: (1) separation of traffic steering and packet processing in the FEs; (2) separation of SDN and NFV control in the FEs. Our HSN prototype, built on NetFPGA-10G, demonstrates that the processing performance can be greatly improved with only a small modification of the traditional SDN/NFV architecture.

In the design of industrial chimneys and towers, structural engineers must assume a level of the inherent damping in the structures. In order to better estimate the dynamic response of those structures, actual damping was measured from wind-induced vibration signals of chimneys and towers and its characteristics with respect to the response levels, the structural systems, and the wind direction were discussed. Damping ratio and natural frequency for three chimneys and two towers were calculated using random decrement technique.

In the case of designing autonomous robot architecture using deliberative and reactive control methods, we can use mixed hybrid form as well as purely reactive scheme or purely deliberative scheme respectively according to its own goal and environment within the robot operates, It needs time and endeavors to design robot control architecture in either case above. In our research, we implemented a 3-dimensional robot simulator in order to help designing reactive/deliberative autonomous robot control architecture by offering methods which is capable of selecting design parameters and confirming its performances. It can be used, of course, to design purely reactive or purely deliberative architecture. The architecture and performance of simulator is shown and a sample hybrid robot architecture designed with the simulator is introduced in this article.

Purpose: Analysis on the spatial configuration characteristics of dental department in medical center through examining outpatient department of medical center is necessary for the development of architectural planning of the dental healthcare system in Korea. This study has been performed to provide data for the planning of hospital architecture. Methods: Literature review of dental healthcare system and investigation on current status of dental department in medical center have been conducted. The plan and spatial configuration of seven medical centers in Seoul area have been analyzed. Results: The result of this study can be summarized in four points. The first one is that the clinical dental spaces are classified by dental school's dental hospital, dental department in medical center, dental hospital, private dental clinic, and public dental healthcare center in Korea. The second one is that the dental department in medical center is a result from medical law regulation and it is specified and subdivided with dental specialist system. The third one is that the types of the dental department in medical center are divided into independent type or comprehensive type according to the relationship with main outpatient department. The fourth one is that the spatial configuration of dental department in medical center is planned with 5-7 specialized departments and they are allocated in the dental department. Implications: In addition to the spatial configuration of dental department in medical center, it is necessary to analyze the other factors like circulation, relationship with other facilities in medical center to develop the dental healthcare system.

Purpose: With the rapid development of technology and individual life styles, Korea faces ever-increasing mental diseases caused by divorce, suicide, alcohol, drug addiction, and internet addiction. To reflect this, the quantitative expansion of mental health centers that make up is time. The purpose of this study is to understand the current situation of standard mental health centers by analysing Seoul's cases of mental health. First, this study presents the direction of mental health policy through specific examples about the function of public and private sectors. Second, advantages and disadvantages of the facilities will be delineated through in-depth comparisons and analyses, ultimately providing architectural quidelines for establishing future standard mental health center. Methods: Data were collected through literature research, field surveys, and expert interviews to standard mental health centers in Seoul. In the field investigation, we collected various data(architectural plan, dimension, photos) by visiting standard mental health centers. Data were analysed by content analysis. Results: The result of this study can be summarized into three points. The first one is that Mental health environment changing role of the mental health center is derived the spatial variations. The second one is that Standard Mental Health Center is divided into four sectors. Implications: It is necessary to give and architectural suggestion of mental health center in response to the proposal of the system.

For the large-sized and post-ultra definition TFT-LCD, improved drivability is prerequisite not only for the integration of driving circuit on glass but also for the chargeability of each pixel. In order to meet required drivability, currently adopted process architecture and materials are modified for the RC delay reduction, including the drastic increase of gate bus thickness and its related solution for step coverage. We present new process architecture and material selection for the next generation TFT-LCD devices.

In this paper, tunable SC(switched capacitor) 2nd order bandpass $\Sigma-\Delta$(Sigma-Delta) modulator with novel architecture that can adjust the IF band center frequency by one coefficient value is proposed for data conversion in the IF(Intermediate Frequency) band. Its architecture can optionally adjust all the 2nd order noise transfer function in comparison with the conventional architecture. In order to adjust the center frequency, the conventional architecture needs the two variable coefficient values, basic clock and eight clocks. On the other hand, the proposed architecture can adjust the center frequency by one variable coefficient value and basic clock only.

The new mobile edge network architecture has been required for an increasing amount of traffic, quality requirements, advanced driver assistance system for autonomous driving and new cloud computing demands on highway. This article proposes a hierarchical cloud computing architecture to enhance performance by using adaptive data load distribution for buses that play the role of edge computing server. A vehicular dynamic cloud is based on wireless architecture including Wireless Local Area Network and Long Term Evolution Advanced communication is used for data transmission between moving buses and cars. The main advantages of the proposed architecture include both a reduction of data loading for top layer cloud server and effective data distribution on traffic jam highway where moving vehicles require video on demand (VOD) services from server. Through the description of real environment based on NS-2 network simulation, we conducted experiments to validate the proposed new architecture. Moreover, we show the feasibility and effectiveness for the connected car media service on highway.
