  • Community Health Planning has been used in public health centers for over 10 years, but little is known about its effect and how it is utilized by public health centers. This paper examines the effect of Community Health Planning on public health centers'organizational performance through the use of the Structural Equation Modeling(SEM) technique. We conducted e-mail surveys of chiefs, people in charge of planning and other staff members in all the public health centers in the country. The instrument measured self-evaluated levels of Community Health Planning, implementation and the effect on the public health centers. The model of the SEM technique has five latent constructs: requirements of planning, plan formulation, implementation, organizational capacity and performance. The SEM technique validated the instrument used in the study and exhibited a relatively good fit. Results of this study were as follows. First, the requirements of planning have positive effects on plan formulation. Second, plan formulation has positive effects on organizational capacity but plan implementation doesn't. Third, there was no statistically significant path between plan formulation, implementation and performance. Fourth, organizational capacity has positive effects on performance. Consequently, this study revealed that Community Health Planning has a positive influence on organizational performance through organizational capacity.

  • SAR(Synthetic Aperture Radar) 영상의 화질을 개선하기 위한 autofocus 기법 중에 대표적 인 것이 PGA(Phase Gradient Autofocus) 이다. PGA는 고차항 위상 오차를 추정할 수 있으며 잡음이 많은 환경에 강인성을 가지는 장점이 있지만, spotlight 모드에 최적화 되어있는 기법으로 stripmap 모드에서 사용하기에는 부적합하다는 단점이 있다. 본 논문에서는 PGA를 stripmap 모드에서 적용한 기법을 소개하고, PGA 성능에 많은 영향을 미치는 ROI(Region of Interest) 선정 방식을 제시하였다. 또한 제안된 기법은 먼저 점표적 시뮬레이션을 통해 검증되었고, 최종적으로 이를 실제 비행 시험을 통해 획득한 SAR 원시데이터에 적용하여 SAR 영상 화질을 개선시킨 결과를 보였다.

  • 자바에서는 가상기계와 프로파일러의 통신을 목적으로 JVM TI 같은 프로파일러 인터페이스를 제공한다. 그러나 자바 가상기계 구현명세는 프로파일러 인터페이스 구현을 요구하지 않는다. 따라서 프로파일러 인터페이스를 제공하지 않는 자바 가상기계에서는 JVM TI를 사용하는 프로파일러는 이용할 수 없다. 이러한 문제를 해결하기 위해서 코드 삽입 기법을 이용해서 프로파일러 인터페이스를 사용하지 않고 힙 사용정보를 분석하는 기법을 제안한다. 제안한 방법을 검증하기 위해서 코드 삽입기를 구현하였다. 실험은 공개되고 자주 사용되는 자바 응용 프로그램을 대상으로 하였고, 실험결과는 대상 프로그램에서 생성된 객체의 수와 최대 할당된 객체의 수 그리고 객체의 사용형태를 보여준다.

  • Fixslicing AES는 Bitsliced AES의 선형 계층에서 많은 Cycle이 발생하는 것을 최소화하기 위해 Shiftrows 단계를 생략한 기법으로 Bitsliced 기법 대비 30% 성능 향상을 보여준다. 하지만 생략된 Shiftrows를 보완하기 위해 코드량이 증가되기 때문에 Shiftrows를 절반만 생략한 Semi-Fixsliced와 완전히 생략한 Fully-Fixsliced로 나뉜다. 본 논문에서는 사전 연산 테이블 기법을 활용한 RISC-V 상에서의 Fixslicing AES의 CTR 모드 구현을 제안한다. CTR 모드의 특징을 활용하여 2-라운드 SubBytes 연산까지의 사전 연산을 통해 암호화 과정에서 2-라운드 SubBytes까지 생략한 빠른 암호화가 가능하다. 해당 기법을 활용하여 32-bit RISC-V 상에서 Semi-Fixsliced는 하나의 블록을 암호화하는 비용은 1,345 Cycle이며 기존 대비 7%의 성능 향상, Fully-Fixsliced는 1,283 Cycle 이며 기존 대비 9%의 성능 향상을 확인하였다.

  • In this paper, we propose a developing approach of 600 W super high frequency(SHF) traveling wave tube amplifier (TWTA) for communications. Also, we make a TWTA called the experimental-TWTA(ETWTA), which uses a cathode ripple reduction technique to improve RF performance. After implementation, we discuss, and compare it with some other TWTAs. Its RF performance is better than that of other TWTAs. Therefore, this methodology can be used to develop the high power SHF TWTA for communications.

  • This paper investigates the performance of the hyperbolic position location(PL) technique in CDMA system. Hyperbolic PL systems are such technology that can provide accurate PL information using the existing cellualr/PCS infrastructure and without requiring additional hardware/software implementation within the mobile unit. The channel simulation is obtained by applying AWGN and multipath fading. The effect of the mobile position within the cell and the number of base stations on the accuracy of the hyperbolic PL technique is investigated.

  • The purpose of this study was to identify hair salon's implementation strategies and current service condition for mass customization. The questionnaire was composed of 82 questions. 115 hair salon's directors were subjects of this study. The results were as follows: Hair salon's mass customization strategies were categorized into 6 factors such as staff's technique, communication service, electronic products, monetary support, man-to-man service, and dissatisfaction removal service. Hair salons were categorized into 2 groups of a high implementation group and a low implementation group. A high implementation group had a higher monthly sales and more regular customers and staff. The hair salons were franchises and were more spacious in the high group. They were located at fashion street, department store, or outlet mall, and offered fashionable hair styles. However, a low implementation group had a lower monthly sales and less regular customers and staffs. The size of hair salon was small in the low group. They were located in residential areas and offered basic hair styles.

  • The need for appropriate technology in global health has expanded dramatically as the gap between industrialized and developing countries continues to expand. However, there is no collective knowledge of appropriate technology in global health. Thus, this study intends to provide light on the latest developments in the field of appropriate technology in global health and to speculate on future directions. A rapid review, or simplified technique, was used to systematically identify and summarize emerging papers. The search technique used the keywords "global health" and "appropriate technology." The total number of papers collected from PubMed and Scopus was 427, and 19 articles were thoroughly reviewed for the result section following the research. The study's conclusions included the following: 1) an assessment of appropriate technology adopted in developing countries; and 2) strategies for implementing appropriate technologies in global health. Additionally, we drew lessons and identified problems to serve as a useful guide for future research and development in appropriate technology. This review uncovered a small but valuable level of information about acceptable technology in global health.
