송치호,황정욱,안수현,안희준 한국공업화학회 2019 한국공업화학회 연구논문 초록집 Vol.2019 No.0

Recently, the rapid development of foldable, rollable displays and electronic devices are accelerating an increasing necessity of flexible and miniaturized energy storages such as micro-supercapacitors (MSCs). However, many attempts have drawbacks such as materials, energy and time consuming and require multiple steps. In this study, we have fabricated flexible asymmetric hybrid MSCs by using a printing technique and an intense pulsed white light (IPWL) technology. By these methods, micron-sized electrode patterns can be easily fabricated on flexible substrate and reduced graphene oxide and metal oxide micro-patterns can be accomplished within milliseconds by irradiating the IPWL with high energy density on graphene oxide and metal oxide precursor patterns, which is exceptionally faster than other grapheme reduction and metal oxide formation methods. The prepared micropatterns are utilized as MSC electrodes, and their electrochemical performance and characteristics are discussed.

송치호,김치경,이시은,최현철 한국전산구조공학회 2016 한국전산구조공학회논문집 Vol.29 No.5

최근에 각광받고 있는 3D BIM기반 철근 물량 산출 현황을 살펴보면 상용 BIM 도구들이 철근 모델링 기능을 제공하지만 그 기능을 이용해서 철근을 모델링하려고 하면 방대한 양의 모델링 시간이 소요가 되어 현재 실용적으로 사용할 수 있는 BIM 소프트웨어는 없다. 본 연구에서는 BIM 기반 설계 현업에서 실용적인 철근 물량 산출 프로세스를 정리 및 제시하고, 초기설계단계의 단면 정보가 없는 상태에서 기존의 2D방식에 비하여 보다 정확하게 기동, 보, 슬래브, 벽체의 철근 단면 정 보를 자동으로 배근해주는 프로그램인 Rebar Automatic Arrangement Program(이하 RAAP)을 개발하였다. 본 연구 결과는 건설프로젝트의 초기 설계단계에서 설계 진행상 구조 부재 단면 설계가 완료되지 않은 상태의 골조 물량 산출 시 적은 노력 으로 기존의 2D기반 방식보다 신뢰성을 향상시킨 물량을 산출할 수 있는 기술로 발전시키는데 의미가 있으며, 합리적인 초 기 설계단계의 물량 산출 프로그램을 구축할 수 있는 기초 연구로서 활용될 수 있을 것으로 기대된다. In the meantime, looking at the present status of how to estimationte the quantity of rebar based on 3D BIM getting the limelight in these days, commercial BIM tools provide rebar modeling functions however it takes a vast amount of modeling time for modeling of rebar in use of that function hence there is no BIM software at present for practical use. Therefore, in this study, we organized and presented a practical rebar quantity estimationtion process in BIM-based design work-site and intended to develop a program named Rebar Automatic Arrangement Program - hereinafter called RAAP - which enables automatic rebar arrangement based on much more precise cross-sectional information of bars in column, beam, slab and wall than the one from existing 2D method under the conditions without any cross-sectional information in the initial design phase. In addition, we intended to establish rebar quantity estimationtion process in the initial design phase through interworking of modeling & quantity estimationtion functions in consideration of joint, anchoring length of BuilderHUB as a BIM software with RAAP. The results from this study are practical in developing a technology that is able to estimationte quantity with more improved reliability than the one from existing 2D-based methods with less effort when the quantity of framework is estimationted in the uncompleted state of cross-sectional design for structural members in the initial design phase of a construction project. And it is expected that it could be utilized as a basic study from which a reasonable quantity estimationtion program can be established in the initial design phase.

송치호,안희준,John A. Rogers,김종만 한국고분자학회 2015 Macromolecular Research Vol.23 No.1

Electrohydrodynamic (EHD) jet printing is a direct-writing technique which ejects ink through a fine nozzleusing an electric field, which has the advantages of high-resolution, rapid printing speed and a wide range of inkselectivity. In this article, the EHD jet printing system is utilized to print patterns of polystyrene (PS) nanofibers. Theeffect of parameters such as ink concentration, working distance, applied voltage, and stage speed on the diameterof the printed nanofibers was investigated. The EHD jet printing technology is further utilized to print various patternsof polydiacetylene (PDA)-embedded PS nanofibers. The EHD jet printing based nanofiber printing is advantageousover conventional electrospining based approaches in terms of patterned PDA images. In addition, an advancedEHD jet printing system which is adopted for aligned nanofiber printing will expand the application of nanofibersfrom bio and chemical sensors to tissue engineering and electronics.

만성질환이 있는 독거 노인의 의료비 과부담이 우울에 미치는 영향에서 기초연금 소득액의 조절효과

송치호 한국자치행정학회 2024 한국자치행정학보 Vol.38 No.1

본 연구는 만성질환이 있는 독거 노인의 의료비 과부담이 우울에 미치는 영향에서 기초연금 소득액의 조절효과 검토를 목적으로 한다. 기초연금 효과에 대한 선행연구들은 노인의 소득, 지출, 빈곤지위와 같은 경제적 측면만큼 비경제적 측면, 특히 우울과 같은 정신건강의 변화에 상대적으로 관심이 적었다. 본 연구는 한국복지패널조사 자료(10차-17차)와 고정효과 패널회귀분석을 사용하여 만성질환 있는 독거 노인 전체 그리고 연령과 성별을 조합한 4개 하위집단별 분석을 실시했다. 분석결과, 기초연금 소득액의 조절효과는 만성질환이 있는 독거 노인 중 전기남성에서만 (-)로 유의미했다. 본 연구는 이 연구결과가 기초연금제도의 개선 또는 재구조화에 주는 이론적·정책적 함의를 제시했다. The purpose of this study is to examine how basic pension income mitigates the impact of medical expense overburden on depression among chronically ill older adults living alone. Previous research on the effects of the basic pension has mainly focused on economic aspects such as changes in income, expenditure, and poverty status of the older adults, overlooking non-economic aspects, in particular changes in mental health such as depression. Using data from the Korea Welfare Panel Study (Waves 10th-17th), fixed-effects panel regression analysis was conducted for the entire sample and by four subgroups: young-old men, young-old women, old-old men, and old-old women. Results indicated no significant interaction effect between medical expense overburden and basic pension income for the entire sample; however, a significant negative interaction effect was found for young-old men. The study discusses the implications of these findings for theory and policy regarding the improvement or restructuring of the basic pension system.

행정정보데이터세트의 데이터 품질평가 연구

송치호,임진희 한국기록학회 2022 기록학연구 Vol.- No.71

In 2019, the pilot project to establish a record management system for administrative information datasets started in earnest under the leadership of the National Archives. Based on the results of the three-year project by 2021, the improved administrative information dataset management plan will be reflected in public records-related laws and guidelines. Through this, the administrative information dataset becomes the target of full-scale public record management. Although public records have been converted to electronic documents and even the datasets of administrative information systems have been included in full-scale public records management, research on the quality requirements of data itself as raw data constituting records is still lacking. If data quality is not guaranteed, all four properties of records will be threatened in the dataset, which is a structure of data and an aggregate of records. Moreover, if the reliability of the quality of the data of the administrative information system built by reflecting the various needs of the working departments of the institution without considering the standards of the standard records management system is insufficient, the reliability of the public records itself can not be secured. This study is based on the administrative information dataset management plan presented in the “Administrative Information Dataset Recorded Information Service and Utilization Model Study” conducted by the National Archives of Korea in 2021. A study was conducted. By referring to various data, especially public data-related policies and guides, which are being promoted across the government, we would like to derive quality evaluation requirements in terms of records management and present specific indicators. Through this, it is expected that it will be helpful for record management of administrative information dataset which will be in full swing in the future. 2019년부터 국가기록원의 주도로 행정정보데이터세트 기록관리체계구축 시범사업이 본격적으로 시작되었다. 2021년까지 3년에 걸친 사업의 결과를 바탕으로 개선된 행정정보데이터세트 관리방안이 공공기록물 관련 법령과 지침에 반영될 예정이다. 이를 통해 행정정보데이터세트는 본격적인 공공기록관리의 대상이 된다. 공공기록이 전자문서 중심으로 전환되었고 행정정보시스템의 데이터세트까지 본격적인 공공기록관리의 대상으로 포함되었지만, 기록을 구성하는 원 자료(raw data)로서의 데이터 자체의 품질 요건에 관한 연구는 아직 부족한 상황이다. 데이터 품질이 보장되지 않으면 데이터의 구성체이며 기록의 집합체인 데이터세트는 기록의 4대 속성 전체가 위협받게 된다. 더욱이 표준기록관리시스템의 규격을 고려하지 않고 기관 실무 부서의 다양한요구를 반영하여 구축된 행정정보시스템의 데이터는 기록관리 관점에서 그 품질에 대한 신뢰성이 부족할 경우 공공기록 자체의 신뢰성을확보할 수 없을 것이다. 본 연구는 2021년 국가기록원에서 진행한 “행정정보데이터세트 기록정보 서비스 및 활용모형 연구”에서 제시된 행정정보데이터세트 관리방안을 기반으로, 적극적으로 개념이 확장된 평가, 그중에서 데이터품질평가에 관한 연구를 수행하였다. 범정부적으로 추진되고 있는 다양한 데이터 , 특히 공공 데이터 관련 정책과 가이드를 참고하여 기록관리 차원에서의 품질평가 요건을 도출하고, 구체적인 지표를 제시해보고자 한다. 이를 통해 향후 본격화될 행정정보데이터세트 기록관리에 도움이 되기를 기대한다.
