        The Aassociation Between the Basic Old-Age Pension and Depression of the Older Adults in Korea

        김재원,이태진,김정석 대한예방의학회 2020 Journal of Preventive Medicine and Public Health Vol.53 No.5

        Objectives: The purpose of this study was to investigate the association between the Basic Old-Age Pension (BOP), which is a non-contributory pension, and depression in BOP beneficiaries in Korea. Methods: We used the second and third waves (2007-2008) of the Korea Welfare Panel Study to identify the effect of the BOP on mental health in the year of its introduction. The Center for Epidemiological Studies-Depression Scale, applied in a Korean context, was used to evaluate mental health. To analyze the effect of the BOP, a difference-in-difference approach was used in analyses of all subjects and subgroups. Results: For this study population of 760 adults, the BOP did not have a statistically significant relationship with depression in its beneficiaries. After controlling for type of household, the BOP was still not associated with lower reporting of depression, either in single-beneficiary or double-beneficiary households, in the year of the benefit. Conclusions: The BOP policy had no significant relationship with the level of depression among recipients. However, this should not be interpreted as implying that income subsidy programs for older adults, such as the BOP, do not affect mental health, considering the importance of economic hardship in this population and the program’s socioeconomic effects.

        축류팬의 성능 평가 및 주변 유동 특성

        김재원,정윤영 대한설비공학회 2000 설비공학 논문집 Vol.12 No.11

        Comprehensive work is done for flows by an axial fan by experimental research. The present model fan is used for air handling device for out-door unit of an air conditioner in home appliance. PIV(Particle Image Velocimetry) system and wind tunnel are adopted for measurements of flows and performance evaluation, respectively. Major experimental conditions are the installation depth of a fan into a bellmouth of it. Optimal position of a fan in an inlet guide tube is observed by examination of fan-performance and flows in both upstream and downstream of the fan. Consequently, in the case of the fan inserted in half depth into the inlet tube, the efficiency of fan shows its maximum value and flow patterns is also streamlined.

        Dynamic analysis of an axially moving robot manipulator supported by bearings

        김재원,정진태 대한기계학회 2017 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.31 No.7

        In this study, a robot manipulator is modelled as a cantilever beam, which moves in an axial direction, has a lumped mass at the end, and is supported by intermediate springs. Considering the tip mass and intermediate springs in the modeling, we derive the equations of motion in which the rigid-body motion is coupled with the flexible motions, and then analyze the transverse vibrations of the beam. Furthermore, we study the tip mass effects on the natural frequencies and the corresponding mode shapes. The natural frequency loci veering is analyzed for variations in the tip mass and the spring position/stiffness. In addition, we investigate the exchange and localization of modes around these veering regions as well as the parameter effects on the mode shapes. Using a Short-time Fourier transform (STFT), the relationship between the dynamic characteristics and dynamic responses are described. It is found that the dynamic characteristics of the beam are dependent on the veering distance. It is also shown via dynamic responses that the mode exchanges occur when a veering distance is close.

        Pre-anesthetic sedative effect of dexmedetomidine in laparoscopic cholecystectomy performed under general anesthesia

        김재원,이혜림,박주승,김지훈,유건희 대한마취통증의학회 2018 Anesthesia and pain medicine Vol.13 No.1

        Background: This study evaluated the effects of pre-anesthetic administration of dexmedetomidine on sedative, cardiovascular, and recovery parameters. Methods: This was a prospective, randomized, double-blind, placebo-controlled study. We selected 60 patients who were scheduled to undergo laparoscopic cholecystectomy. They were randomly divided into two groups and received 0.5 mg/kg of dexmedetomidine (group D) or normal saline (group S) over 10 minutes before induction of anesthesia. The Ramsay sedation scale (RSS) score and bispectral index (BIS) were recorded after completion of the dexmedetomidine infusion. Mean arterial pressure (MAP), heart rate (HR), peripheral pulse oximetry, cardiac output (CO), and systemic vascular resistance (SVR) were recorded. The modified Aldrete recovery score (MARS) was recorded in the recovery room. Results: After completion of the dexmedetomidine infusion, BIS reduction was less than 20% (97.1 ± 2.4, 83.8 ± 4.8; P < 0.001), but RSS-rated sedation was appropriate (P < 0.001). HR was lowest at the end of the dexmedetomidine infusion and there was a significant difference between groups (P < 0.001); however, MAP was not significantly different between groups (P = 0.139). CO was lowest and SVR was highest at the end of the dexmedetomidine infusion. There was no significant difference in MARS values between groups (P = 0.190). Conclusions: A pre-anesthetic dexmedetomidine (0.5 mg/kg) provided appropriate sedation without serious changes in cardiovascular parameters or a prolonged recovery time.

        영한번역에서의 몇 가지 검토사항들

        김재원 중앙대학교 외국학연구소 2018 외국학연구 Vol.- No.43

        This paper aims to give English-Korean translation learners substantial help in improving the quality of their translations. In this study, the translation editing process is divided into two processes. At the first filtering process, mistranslation and translationese in the translated texts must be removed on the basis of ‘accuracy’, ‘appropriacy’ and ‘naturalness’. At the second filtering process, which is the core part of this study, it is necessary that the translated texts conform to the linguistic features and structures of the target language. The data that serves as a basis for this explanation is taken from the students’ translation assignments and other sources. The author hopes the research will contribute to triggering further discussion on the study of how to enhance the quality of the English-Korean translation.

        김재원,손동철 한국정보통신학회 2005 한국정보통신학회논문지 Vol.9 No.7

        For the efficient and safe navigation management of ships cruising across oceans, international maritime law environments have been reinforced and the demand of information sharing between ships and shore has also been increasing. According to these environments and demand, researches about digital ships, ship integration, and ship integration networks have been active recently in US and Europe. In this paper, we first investigate about the proper ship integration platform, and then design and implement a ship integration network based upon the ship integration platform. We construct networks connecting various devices and systems into a layered architecture, and design an integration protocols. Based upon this architecture and protocols, we implement an ship integration system which manages all data and information of ship in a standardized platform and support ship-shore information sharing through which the more efficient and safer ship navigation management are supported with help from shore. We test our ship integration system by applying it to real operating ships and we find our system reliability and verify the efficiency of ship-shore information sharing and management. 대양을 운항하는 선박들의 효율적이고 안전한 운항 관리를 위해 국제 해상법적 환경이 강화되고 있으며, 선박과 육상간의 정보 공유에 대한 요구가 증대하고 있다. 이에 따라 디지털 선박, 선박 통합화 플랫폼, 선박 통합화 네트워크에 대한 연구가 미국과 유럽 등에서 활발히 진행되고 있다. 본 논문에서는 선박 통합화 플랫폼을 연구하고, 선박 통합화 시스템 구축의 핵심이 되는 선박 통합화 네트워크의 설계 및 구현을 수행하였다. 선박 내 각종 시스템 및 기기들을 계층별 네트워크를 구성하고 통합화 프로토콜을 설계하였으며, 선박 통합 정보들을 표준화된 플랫폼으로 관리하고 필요한 정보를 선박-육상 네트워크를 통해 육상으로 전송하여 육상에서 관리 및 지원이 가능한 시스템을 구현하였다. 또한 설계구현된 선박 통합화 시스템을 실제 운용중인 선박에 적용하여 시스템의 신뢰성 및 선박-육상간의 지원체계의 효용성을 확인하였다.

        경제적 불안정과 중년 남성의 정신건강

        김재원,이태진 한국보건경제정책학회 2018 보건경제와 정책연구 Vol.24 No.1

        경제적 불안정과 이에 따라 발생하는 경제적 필요와 경제적 자원의 불일치는 개인의 정신건강에 부정적 영향을 줄 가능성이 매우 높다. 한국 사회에서 중년 남성들은 일반적으로 생계부양의 책임을 지고 있으나 상당한 경제적 불안정에 노출되어 있다. 본 연구에서는 경제적 불안정을 세 단계로 구분하여 정의하였고, 한국복지패널조사(Korea WElfare Panel Study) 3차-10차 자료를 이용한 다수준패널분석을 통해 한국 중년 남성들에 대한 경제적 불안정의 영향을 확인하였다. 분석 결과, 분산으로 측정된 소득 변동성 지표를 제외한 모든 변수가 우울에 통계적으로 유의미한 영향을 주었다. 자살생각에 대한 분석에서는 소득만족도만이 유의미한 영향을 나타내었다. 경제적 불안정의 다양한 지표들의 영향력이 확인되었으므로, 소득 외에 경제적 불안정과 관련된 다른 요인들도 정신건강에 위험요인으로 작용할 수 있음을 알 수 있다. 본 연구는 경제적 불안정의 건강 영향을 추정하였는데, 소득 수준이 아닌 변동성이나 소득에 대한 주관적 인식 등이 특히 정신건강에 부정적인 영향을 줄 수 있음을 밝힌 초기 연구로서 중요한 의의를 지닌다. Economic insecurity and resultant inconsistency in economic needs and economic resources are likely to have a negative effect on one's mental health. Middle-aged men in Korean society are generally responsible for supporting a living but are exposed to considerable economic instability. The study defined economic insecurity in three stages and analyzed the impact of those indicators for mental health of Korea's middle-aged men using the data from KoWEPS 3rd - 10th wave. The analysis shows that all variables other than income volatility B(income dispersion for whole period) have a statistically significant effect on the depression. In the analysis on suicidal thoughts, only income satisfaction had significant effects. Having identified the impact of the various indicators of economic instability, it can be recognized that other factors related to economic insecurity besides income may pose a risk to mental health. The results of this study estimated the health effects of economic insecurity, suggesting that the variability of income, not the income level, or subjective perception·emotional responses about one’s economic status may have a negative impact on mental health.

        폴리아크릴아미드 겔을 이용한 유방확대술의 초음파 및 유방촬영술 소견: 증례 보고

        김재원,최선형,정수영,양익,윤세라 대한초음파의학회 2009 ULTRASONOGRAPHY Vol.28 No.3

        Polyacrylamide gel has been widely used for soft tissue contouring for more than 30 years and has been used for breast mammoplasty augmentation in China since 1997. As Korea is close to China, Korean clinicians often encounter the patients who have undergone polyacrylamide gel augmentation mammoplasty. Therefore, radiologists should know the ultrasonographic and mammographic findings and the complications of polyacrylamide gel augmented mammoplasty; this can be helpful in the diagnosis and management of those patients. We report the characteristic radiological findings of a patient who had undergone mammoplasty augmentation with polyacrylamide gel. 폴리아크릴아미드 겔은 30년 이상 연조직 성형에 광범 위하게 사용되어 왔으며, 1997년 이후로 중국에서 유방 확대성형에 이용되어 왔다. 우리나라는 중국과 인접해 있 어 유방영상 검사 시 폴리아크릴아미드겔로 유방확대술을 시행받은 환자를 접하는 일이 잦다. 따라서 영상의학과 의 사는 폴리아크릴아미드겔을 사용한 유방확대술의 초음파 및 유방촬영술 소견과 합병증에 대해서 알아야 하며 이는 이런 환자들의 진단과 치료에 도움을 줄 수 있다. 우리는 폴리아크릴아미드겔을 이용한 유방확대술을 시행받은 환 자의 특징적인 영상 소견을 보고하고자 한다.

        유동 저항에 따른 원심홴의 선정

        김재원,장동희,안은영,Kim Jae-Won,Jang Dong-Hee,Ahn Eun-Young 한국유체기계학회 2006 한국유체기계학회 논문집 Vol.9 No.3

        Comprehensive experimental works are carried out for the optimal design of a centrifugal blower adopted in an indoor unit of an air-conditioner. The models for consideration are typical multi-blade turbo blower and limit loaded one, respectively. The main interest lies on the fluid dynamics performance when the blower Is installed in the practical system. The methodologies are an experimental estimations with a wind tunnel for blower performance and PIV measurement for the detail flow information. A centrifugal blower with limit loaded fan shows pronounced performances in terms of the flow rate and static pressure rise and the reason is explained by the precise measurement of the flows between blades using PIV. Consequently, it is found that the blower is proper for the flows with a resistance in down stream such as a heat exchanger.
