Purpose: Tuberculosis(TB) care unit in public health center should be carefully considered to be re-designed as an infection safety environment for both patient and healthcare workers. So, for the enhancement, this study analyses the facility requirements for co-using the screening clinic as a TB and other respiratory disease care unit. Methods: Not only screening clinic facility guidelines from "A Study for Standard Triage Design and Construction Document" but also the guidelines of TB care and related medical facility are reviewed; KDCA, CDC, ECDC and WHO as a TB care, and FGI and NHS for facility. The facility requirements are summarized space, approach, and mechanical requirement in order. By comparing the summary and screening clinic facility guidelines, supplementations are proposed for TB care unit setting. Results: The result of this study shows that both the space program and mechanical requirement of the screening clinic and that of TB care unit are almost identical and could be share, which include direct airflow or negative air pressure in an exam room. To increase functional and economical efficiency, however, it is necessary to consider a multi-functional negative pressured room, So care process may be re-designed based on a room type; face-to-face room or glass wall inbetween. Implications: The facility guidelines for TB care unit of a public health center should be developed to build a safe environment for infection control by reflecting its medical plan and budget.

Acquired defects involving exposed bone on the forehead is challenging to reconstruct. Skin expansion provides an ideal thin flap for forehead aesthetic unit, but it takes long time and high cost, and many patients are dissatisfied at their figures. Free flap can provide enough tissue immediately, but it takes long time and has the risk of mismatches of color and texture. This report details our experiences with two patients who had soft tissue defect on their forehead that was covered with remnant forehead flap unit. This method uses one-unit-forehead island flap based on supratrochlear and supraorbital vessel. We obtained satisfactory results in terms of aesthetic and functional consideration.

상거래와 통신을 위한 주된 매개체로써 등장한 인터넷 뿐 아니라 새로이 대두되는 다양한 유무선 네트워크 환경, 그리고 정보 저장에 있어서 암호화 알고리즘은 보안의 중요한 요소로 자리잡고 있다. 본 논문에서는 대칭 및 비대칭 암호화 알고리즘을 가속시키기 위한 암호화 프로세서의 명령어와 해당 Functional Unit 을 제안하였다. 현재 암호화 알고리즘을 가속시키기 위한 방법으로 사용되는 주문형 반도체(ASIC)는 알고리즘 가속 속도는 빠르지만, 새로운 암호화 알고리즘을 지원할 수가 없고, 지원하는 알고리즘을 사용하지 않는 경우 비효율성을 야기한다. 또한 범용프로세서는 다양하고 새로운 암호화 알고리즘을 지원할 수 있지만 암/복호화 가속속도가 느리다. 이는 암호화 알고리즘이 범용 프로세서에서는 지원하지 연산을 주로 사용하기 때문이다. 따라서 이 논문에서는 대칭 및 비대칭 암호화 알고리즘의 주된 연산을 분석하고, 각각의 연산을 가속시키기 위한 명령어 집합, 그리고 해당하는 Functional Unit을 제안하여 Programmable 한 암호화 프로세서를 설계하기 위한 토대를 마련한다.

A functional suspension model is proposed as a kinematic describing function of the suspension, that represents the relative wheel displacement in polynomial form in terms of the vertical displacement of the wheel center and steering rack displacement. The relative velocity and acceleration of the wheel is represented in terms of first and second derivatives of the kinematic describing function. The system equations of motion for the full vehicle dynamic model are systematically derived by using velocity transformation method of multi-body dynamics. The comparison of test and simulation results demonstrates the validity of the proposed functional suspension modeling method. The model is computationally very efficient to achieve real-time simulation on TMS 320C6711 150 MHz DSP board of HILS (hardware-in-the-loop simulation) system for ECU (electronic control unit) evaluation of semi-active suspension.

Functional protein of MB78 bacteriophage having apparent molecular weight of 22 kDa is expressed from 1.7 kb HindIII G fragment. The nucleotide sequence of this fragment showed two open reading frames of 222 and 196 codons in tail-to-tail orientation separated by a 62-nucleotide intercistronic region. The ORF of 22 kDa protein is present in opposite orientation, i.e. in the complementary strand, preceded by a strong ribosomal binding site and a promoter sequence. Another ORF started from the beginning of the fragment whose promoter region and translational start site lies in the 0.45 kb HincII U fragment which is located next to the HindIII G fragment, that has the sequence for DNA bending. 3' end of the fragment has high sequence homology to the EaA and EaI proteins of bacteriophage P22, a close relative of MB78 phage.

One of the activities to improve software quality in ISO 26262 is to apply the design principles for software unit design and implementation mentioned in ISO 26262-6, including the evaluation activity. Before evaluation activity, the tool is compared and selected for evaluation. Because the results of the tool a company selected might have an effect on product quality. In this paper, we suggest the method to compare industrial static analysis tools with some of "MISRA C : 2004 Exemplar Suite" and all lessons learned from comparing tools are described. The result on comparison shows that we just couldn't rely on a result of Static Analysis Tool and need to have another appropriate processes and guidelines to evaluate a software.

High-level synthesis generates a structural design that implements the given behavior and satisfies design constraints for area, performance, power consumption, packaging, testing and other criteria. Thus, high-level synthesis generates that register-transfer(RT) level structure from algorithm level description. High-level synthesis consist of compiling, partitioning, scheduling. In this paper, we proposed the efficient scheduling algorithm that find the number of the functional unit and scheduling into the minimum control step with silicon area resource constrained.

This study aimed at analyzing the trend of carbon dioxide emission for direct and indirect areas by using inter industry relations table between 2000, 2003 and 2005 in the key building materials and components. Results of this study are as follows; First, the material and components for this study was selected in 20 industries of products such as sand, gravel, cement, concrete articles, rebar, and steel bar. Second, among the 20 selected key building materials, the group with the highest carbon-dioxide emission was shown in ready-mixed concrete, concrete articles, and primary aluminum goods. Third, as a result of analyzing the changes to the units of carbon dioxide emission according to passage of time, the number of items which is changed in such as sustained increase or decrease over time was insignificant in carbon-emission change trend.

This study aimed to analyze the prioritized area for the functional change of agricultural reservoir according to the rapid urbanization and social changes through the mapping method. Changwon-si, Gimhae-si, and Jinju-si in Gyeongnam province were selected as the study area, considering the results of land-use and cluster analysis. As the planning unit of management area, watershed was used and land coverage map from 1975 to 2015 were analyzed for changes of land use. The reduction ratio (%) of farmland was calculated for identifying the changes in 2013 compared to 1975. As a result, the reduction ratio was 11.9% for Changwon-si, 12.2% for Gimhae-si and 9.3% for Jinju-si, and the number of watershed having functionally reduced potential-area was relatively high in the proportion to the city size.

Functional Modeling methodology, IDEF0 is widely used for modeling, analysis and description of enterprise system. The limitation of modeling components restricts applicability and give rise to confusion about model. In this paper, we propose new method to extend IDEF0. The first is adding modeling components which are semantic representations. In addition to ICOMs, we add the time and cost component which is required to execute the function. The second is tracing mechanism. When we need some information, we drive the functions related with the information by reverse tracing of the function which produces the information as a output and input. Through the tracing, we find out the bottleneck process or high cost process. Finally, we suggest the final decomposition level. We call the final decomposed function into unit function which has only one output data. We can combine and reconstruct some of functions because an unit function is similar to ‘lego block’. To reach the integrated system, the main problem to be solved is the integration of information produced by different functional subsystem. This can be resolved when the creation of data must be dependent on only one function. Through view integration of function output, we can guarantee the integrity of data.
