Wire harness is a component for efficient control when electronic parts are required such as construction machinery and electric vehicles. With emerging issues such as autonomous driving and automation in construction, a wire harness composed of multiple cables has become an essential part because more electronic parts are required. However, when a wire harness failure occurs, systems can be stopped, accidents can occur, and economic damage can be significant. Therefore, in this paper, we developed a digital fault screening system that could easily and quickly diagnose faults in the wire harness. The principle of the developed system was to sequentially send pulse signals to the wire harness and use returned signals to perform fault detection. As a result of diagnosing faults using the developed failure detection system, a detection accuracy of 99.9 % was confirmed through the experiments.

소셜 네트워크 데이터를 적용한 서울 사대문 안 옛길 경관의 가치 분석

김선영 서울시립대학교 서울학연구소 2022 서울학연구 Vol.- No.87

The purpose of this study is to understand the scenery of the old streets inside the the Four Main Gates of Old Seoul, preferred by SNS users, which is a new network of relationships that instantly reproduces while sharing all the information that citysumer feel while walking on. I compared, contrasted, and excavated the 「Doseongdaejido」 among the existing city maps and the cadastral map of Seoul in 2015. The historical origins and spatial characteristics of 12 scenic spots including that Okryudongcheon-gil, Samcheongdongcheon-gil, Angukdongcheon-gil, Jesaengdongcheon-gil, Bukyeongcheon-gil, Heungdeokdongcheon-gil, Jeongdong- gil, Namsandongcheon-gil, Pildongcheon-gil, Muksadongcheon-gil, Jingogae-gil, Gurigae-gil were investigated. In order to analyze data by walking area, season, month, and space, from May 1, 2020 to June 30, 2021, I used the Open API to analyze with ArcGIS Pro 2.4 program. Thorough historical verification and restoration are also important in order to secure the competitiveness of various projects related to Seoul’s Old Road. However, it is essential to the strategy of the old road inside the Four Main Gates of Old Seoul to reflect the contemporary paradigm in the city and to understand the preferences of citysumer and apply them to the road. The meaning of the road in the city is not a stuffed relic, but the flow of time, the meaning of space, and the values of the citizens living there. Therefore, it is essential to secure big data on SNS where unspecified people transmit data in real time to exchange opinions and activities. 본 연구는 서울 사대문 안의 옛길을 직접 걸으면서 느끼는 정보를 불특정 다수 와 공유하면서 재생산하는 새로운 관계망인 SNS 이용자들이 선호하는 경관을 파 악하고자 출발하였다. 현존하는 도성도 가운데 가장 크고 정확한 「도성대지도」와 2015년 서울시의 지적도를 비교, 대조, 발굴한 옛길과 옛물길을 포함한 581개의 길 가운데 서울시가 지정한 옥류동천길, 삼청동천길, 안국동천길, 제생동천 길, 북영천길, 흥덕동천길, 정동길, 남산동천길, 필동천길, 묵사동천길, 진고개길, 구 리개길 등 12경의 역사적 유래와 공간적 특성을 조사하였다. 보행영역별, 계절별, 월별, 공간별로 데이터를 분석하기 위해 2020년 5월1일 부터 2021년 6월30일까지 Open API를 활용하여 ArcGIS Pro2.4의 프로그램으로 분석하였다. 서울 옛길과 관련한 다양한 사업의 경쟁력 확보를 위해 철저한 역사 적 고증과 복원도 중요하지만, 동시대의 패러다임 반영과 시민들의 선호도 파악 이 서울 옛길 전략에 필수적이다. 이처럼 도시의 길은 박제된 유물이 아니라 시 간의 흐름과 공간의 의미, 그리고 그곳에서 살아가는 시민들의 가치관을 담기 때 문에, 불특정 다수가 실시간으로 데이터를 전송하여 의견과 활동을 교류하는 체 험의 빅 데이터 확보가 필수적이다.

This study focused on analyzing of diligent learner’s motivation and self-direction in learning according to the purpose of attending the course in online learning. For this purpose, survey was conducted with 119 diligent learners completing over 50% of online course at S university. The results were analyzed by dividing the participants into 2 groups of academic credit learners and self-study learners based on the purpose of attending the online course. As a result, there were a significant difference in 5 types of learning motivation, such as curiosity and excitement, interest on the subject, professor's recommendation, sense of challenge, and self-development, except the knowledge acquisition. In addition, area of learning environment management appeared to have a significant difference among the 4 components of self-direction in learning, such as learning value system, learning skill and strategy, learning performance management and learning environment management. The self-study leaners recognizes themselves as having less ability on the control of the learning environment compare to the academic credit leaners. Therefore, in online learning requiring high intrinsic motivation to success, the need of systematic support such as function for checking self-learning step by sharing other learners' learning history, applying of the course completion system, operating the tutor, and having a meeting, etc. is suggested for the self-study learner, even the diligent learner with highly autonomy in the university context.

LDA 기반 뉴스 빅데이터 토픽모델링을 활용한 디지털 관련 이슈 분석과 정책적 함의

김선영 한국정부학회 2023 한국행정논집 Vol.35 No.3

This study aimed to discover the implications of digital inclusion applied to our social & policy environment by reviewing the literature on the issues being discussed in relation to digital transformation society and social inclusion to explore issues, focused on policies about digital inclusion in our society. And then, issues related to digital inclusion in our society were explored with the news big data analysis. For the big data analysis, LDA topic modeling was conducted on 5,136 news data related to digital between Jan. 01, 2022, and Jan. 31, 2023. The collected data was from BigKinds. As a result of the analysis, it was described that digital inclusion in our society is related to digital issues from an economic perspective rather than any other perspective. The social issues seemed to affect the digital inclusion policies. This study implies the need for digital inclusion following; 1) applying to all members of our society from a specific group expressed as the socially disadvantaged class, 2) the need to conceptualize digital inclusion as distinct from social inclusion, and 3) to prescribe the social meaning of digital inclusion in the digital inclusion policy.

디지타이저를 이용하여 도표로 발표된 물성 데이터들을 정밀하고 신속하게 수치데이터로 환산할 수 있는 알고리듬을 제안하였다. 수치자료화한 데이터를 이용하여 필요한 내삽이나 공정해석에 응용할 수 있는 가시적인 최적화방법에 대하여 검토하였다. Pitzer의 압축인자 도표를 수치화한 후 내삽한 데이터와 이를 원래의 수치데이터 값들과 비교한 결과 도표자료 내삽의 신뢰도를 확인할 수 있었다. 또한 CO₂에 의해 식용대두유를 추출하는 초임계 용매 추출공정에 응용한 결과 용해도 및 용매의 물성도표만으로 분리수율을 증가시키면서 조업에너지 소요량을 최소화할 수 있는 열역학적 최적화 방안을 제안하였다. We presented an algorithm that can constructs digitized databases from various graphical representations such as thermodynamic property charts by utilizing a desk-top digitizer properly. It is found that any types of usual model-oriented process calculation such as interpolations and process optimization can be equivalently accomplished with these digitized property charts. As the first illustration, the compressibility factors for any reduced temperature and pressure can be evaluated quickly and accurately by digitized Pitzer's Z-chart with linear and cubic spline interpolation methods. As the second illustration, optimum operation paths which give maximum separation yield with the least of energy demand can be sought with the digitized property chart for the supercritical extraction process of soybean oil with carbon dioxide.

Objectives : The current study examined the effects of demographic and psychological positive factors on subjective satisfaction with life in patients with depression. Methods : A total of 253 patients (over score of 16 by Beck Depression Inventory-II ; BDI-II) were surveyed with Life Orientation Test-Revised (LOT-R), The Gratitude Questionnaire-Six Item Form (GQ-SIF), The State Hope Scale (SHS), Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale (FACIT-Sp-12), Purpose in Life Test Scale (PLTS), Functional Social Support Scale (FSSQ) and Satisfaction With Life Scale (SWLS). Correlation analysis, Independent t-test analysis, Mann-Whitney analysis, ANOVA, ANCOVA and multiple linear regression analysis were performed to identify the relationship between life satisfaction and variables of demographic and psychological positive factors. Results : Among the demographic factors, age, marital status, occupation, income and religion are related with life satisfaction. Among the psychological positive factors, hope, life orientation, social support, and spirituality are significantly predictors for life satisfaction. After adjusting for BDI-II, however, life orientation, hope, social support were significant predictor for life satisfaction. Conclusion : This findings suggest that positive psychological factors as well as demographic factors effect subjective life satisfaction. Life satisfaction is affected by depressed level, but the intervention improving ‘optimism’ and ‘state hope’ may be helpful for patients with depression.
