        The Associations between income, informal social networks, and health among older adults in South Korea: A multi‐group analysis based on the level of age‐friendly environments

        Sue‐Lynn Kim,Ju‐Hyun Kim,Kyong‐Hee Ju 한국사회복지학회 2019 Asian Social Work and Policy Review Vol.13 No.3

        The aim of the present study was to empirically investigate the role of age-friendly environments (AFE) on the associations between income, informal social networks, and health among South Korean older adults. We used data from the “2017 Age Integration Survey” collected nationally and ultimately analyzed 615 older adults over 50 years of age. Structural equation modeling and multi-group analysis were used to test the hypothesis. Specifically, two groups of perceived levels of AFE (top 25%, bottom 25%) were compared in order to examine the moderating effects. The results indicated that poor income and scarce informal social networks each had a significantly adverse impact on health. However, the effect of income on health was no longer significant for older adults living in environments that were more age-friendly. In both groups, the presence of fewer informal social networks adversely impacted health, although the sizes of the effects decreased when the level of AFE perceived by older adults was improved. Finally, several implications of the study findings were discussed.

      • Problem Domain and Structural Abstractions in Reverse Engineering

        박수희 同德女子大學校 1997 同大論叢 Vol.27 No.1

        본 연구는 소프트웨어 역공학에서의 추상화를 위한 문제를 다루었다. 두 종류의 추상화 방법-문제 영역적과 구조적 방법-이 논의되어진다. 문제 영역 추상화는 프로그램이 쓰여지는 적용 분야에서의 개념과 일치하며 대개의 경우 프로그램 내에 직접 나타나지 않는다. 구조적 추상화는 불필오한 함수적 기술요소 제거하고 루프문의 역할에 대한 요약을 생성해냄으로써 원시코드의 기능에 대한 추상화 된 기술을 위해 사용된다. 문제 영역 추상화는 형식 코멘트언어를 사용하여 이 연구에 도입된다. 이 정보는 코드 내에 삽입되어 구조적 추상화를 사용함에 더욱 간략화 된 기능명세서의 생성을 가능하게 한다. 이 접근 방법은 여러 종류의 COBOL 프로그램에 적용되어 여러 차례의 실험 연구를 통해 원시코드로부터 유용한 추상화 명세서를 생성함이 확인되었다. 또한 이렇게 생성된 명세서가 복잡한 프로그램의 논리를 이해하는데 유지 보수의 관점에서도 도움이 됨을 확인하였다. 본 연구는 계속 추진 중에 있으며 계속 진화와 발전을 거듭할 것이다. 개발 중인 분석도구인 ASPECT(Abstract SPecifications ExtraCtion Tool)는 본 연구에서 제시한 접근 방법을 검증하고 그 복잡성과 전산학적 요구 사항을 식별하는데 도움을 줄 것이다.

      • Thyristor Inverter에 依한 誘導電動機의 運轉特性에 關한 小考

        金秀植 군산대학교 1980 群山水産專門大學 硏究報告 Vol.14 No.3

        It has been considered the steady-state and transient characteristics of an induction motor driven by Thyristor inverter. On the other hand, Thyristor inverter has many advantages in every respect, simplified in circuit, it could be abbreviated other element and widely used normal Thyristor instead of special Thryistor for consist of device. But in respect of practical use and increased electric capacity, it must be need of high voltage Thyri stor When induction motor driven open-loop system, this equipment has some troubles occurred with easily that instability by in proportion as variation of frequency Thyristor inverter. Therefore in this paper described on the operation and characteristics of turn-off action of the Thyristor inverter. I tried to search for the effects of impulse response by overshooting and various parameter that the stability of induction motor driven by Thyristor inverter. I have used method of Root-locus and impulse response for slip or frequency parameter in order to distinguished on stability. Consequently we could be preventing against trouble some of instability. Merely there is something yet to loam that learn proper value of turn-off condenser capacity for reduced terminal voltage swing upward rapidly.

        전세계적으로 지역사회획득 메티실린 내성 황색포도알균에 의한 감염 질환이 증가하고 있으나 아직까지 국내외에서 이로 인한 요로감염의 보고는 없었다. 저자들은 지역사회획득 메티실린 내성 황색포도알균에 의한 신우신염을 진단하고 ciprofloxacin 투여로 성공적으로 치료한 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. In the past decade, methicillin-resistant staphylococcus aureus (MRSA) have emerged in the community, causing serious infection in young and healthy persons without established risk factors for MRSA acquisition. This community acquired methicillin- resistant S. aureus (CA-MRSA) has been usually reported to cause the skin and soft tissue infection and necrotizing pneumonia. We have experienced a case of acute pyelonephritis caused by CA-MRSA without health care-associated risk factors. The staphylococcal cassette chromosome mec (SCCmec) typing and multilocus sequence typing (MLST) revealed the ST5- MRSA-IV clone, which showed SCCmec type IV and MLST allelic profile of ST5 (1-4-1-4-12-1-10).

      • DC-DC CONVERTER의 運轉特性 改善에 關한 硏究

        金秀植 군산대학교 1986 群山水産專門大學 硏究報告 Vol.20 No.3

        In this paper we have described on the characteristics of DC-DC converter using feed-back loop system. And we tried to research for the improvement method of unstable phenomenon and stable condition against feedback constant value, load resistance and input voltage value. And also we intended to get stability for DC-DC converter driving in good condition against troubles. Experimental results are as follows : 1. According as the duty ratio are closely akin to approximate value (=1), the output resistance has increased and the output voltage had the restricted peak value. On the other hand, this value has decreased in proportion to load variation. 2. Load characteristics are limited by stable condition and are subject to restriction in according with various feedback constant value. 3. The less the ratio of inductance value versus filter condenser capacity (L/C) grows, the more the stable region is extended. If we have selected proper value of parameter for DC-DC converter circuit, we could be improved to the characteristics of converter driving because unstable phenomenon depends on the values of inductance and condenser.

        Recently it has been used stator voltage control for Induction motor drive using Thyristor. In order to obtain the force of braking a large that bring it rapidly to standstill, acceration and reducing speed for motor drive repeatly and high degree of efficiency in good condition. Although it has many advantages in every respect, we must be considered about variation of operating point, the Delay-time of Thyristor and differential torque between DC and rectification current. In this paper we should compare with the characteristics of stator voltage control that it contained component of foundmental wave and DC current, tried to research for improvement of Dynamic braking. We have obtained experimental following results. 1.We have obtained a large braking torque in region of lower speed by variation of various Firing angle and inclined toward positive-phase torque in region of high speed, it couldn't generated torque of braking at point of S≤O. 35 in spite of variation of Firing angle. 2.By means of increasing secondary resistor only, we couldn't obtain satisfactable result and couldn't improve characteristics of braking for motor driving. But it could be raised in efficiency by combination of Shunt Thyristor with secondary resistor in parallel we must be take care of the value of secondary resistor, because it has dissipated power in region of high speed. 3.It has been improved to Dynamic braking for motor driving in high degree of efficiency by means of proper value of Firing angle and Extinction angle.
