  • 빅데이터 시대에 정형데이터 뿐만 아니라 비정형데이터를 분석하는 것이 중요한 과제로 대두되고 있다. 정부기관이 생산하는 공문서도 텍스트 기반의 대형 비정형데이터로 빅데이터 분석의 대상이 된다. 기관 내부의 업무효율, 지식관리, 기록관리 등의 관점에서 공문서 빅데이터를 분석하여 유용한 시사점을 도출해 나가야 할 것이다. 그러나, 현재 공공기관이 보유 중인 공문서의 상당수가 개방포맷이 아니어서 빅데이터 분석을 하려면 비트스트림에서 텍스트를 추출하는 전처리 과정이 요구된다. 또한, 문서파일 내에 맥락 메타데이터가 충분히 저장되어 있지 못하여 품질 높은 분석을 하려면 별도의 메타데이터 확보 노력이 필요하다. 결론적으로 현재의 공문서는 기계가독(machine readable) 수준이 낮아 빅데이터 분석에 비용이 많이 들게 된다. 이 연구에서는 향후 공문서가 기계가독 수준을 높이기 위해서는 공문서의 개방포맷화, 기안문 서식의 표준태그화, 자기 기술(self-descriptive) 메타데이터 확보, 문서 텍스트 태깅 등이 선행될 필요가 있다는 점을 제안한다. 첫째, 문서가 스스로를 설명하기 위해 추가되어야 하는 메타데이터 항목들을 제시하고 이 메타데이터들이 기계가독형이 되도록 문서파일에 저장하는 방법을 제안한다. 둘째, 문서 내용 분석 시 자연어 처리에만 의존하지 않고 행정 맥락에 따라 중요한 키워드를 미리 국제표준 태그로 마킹하여 기계가독형이 되도록 하는 방안을 제안한다.

  • Purpose: This study aimed to develop and validate a structural model for the quality of life (QoL) among high-risk pregnant women, based on Roy's adaptation model. Methods: This cross-sectional study collected data from 333 first-time mothers diagnosed with a high-risk pregnancy in two obstetrics and gynecology clinics in Cheonan, Korea, or participating in an online community, between October 20, 2021 and February 20, 2022. Structured questionnaires measured QoL, contextual stimuli (uncertainty), coping (adaptive or maladaptive), and adaptation mode (fatigue, state anxiety, antenatal depression, maternal identity, and marital adjustment). Results: The mean age of the respondents was 35.29±3.72 years, ranging from 26 to 45 years. The most common high-risk pregnancy diagnosis was gestational diabetes (26.1%). followed by preterm labor (21.6%). QoL was higher than average (18.63±3.80). Above-moderate mean scores were obtained for all domains (psychological/baby, 19.03; socioeconomic, 19.00; relational/spouse-partner, 20.99; relational/family-friends, 19.18; and health and functioning, 16.18). The final model explained 51% of variance in QoL in high-risk pregnant women, with acceptable overall model fit. Adaptation mode (β=-.81, p=.034) and maladaptive coping (β=.46 p=.043) directly affected QoL, and uncertainty (β=-. 21, p=.004), adaptive coping (β=.36 p=.026), and maladaptive coping (β=-.56 p=.023) indirectly affected QoL. Conclusion: It is essential to develop nursing interventions aimed at enhancing appropriate coping strategies to improve QoL in high-risk pregnant women. By reinforcing adaptive coping strategies and mitigating maladaptive coping, these interventions can contribute to better maternal and fetal outcomes and improve the overall well-being of high-risk pregnant women.

  • Purpose: The purpose of this study was to identify correlates influencing cognitive impairment in breast cancer patients receiving chemotherapy. Methods: Study subjects consisted of 102 breast cancer patients who received chemotherapy. Subjects were the members of a breast cancer self-help group. Data were collected using structured self-reporting questionnaires including scales of cognitive impairment, physical status, fatigue, quality of life, emotional status, sleeping, family support, and menopausal symptoms. Statistical Package for Social Sciences was used for statistical analyses. Results: Breast cancer patients receiving chemotherapy appeared to show a high level of cognitive impairment. Among demographic characteristics, the effects of economic status and family type on cognitive impairment were found to be statistically significant. Among disease related characteristics, the effect of duration of chemotherapy on cognitive impairment was statistically significant. Menopausal symptoms were positively associated with cognitive impairment. The model including postmenopausal symptoms and caregiver type explained about 66% of variability in cognitive impairment. Conclusion: These findings highlight the importance of contextual factors in understanding cognitive impairment in breast cancer patients receiving chemotherapy and can be used to develop appropriate, effective nursing interventions.

  • The Trust and Authority in Scholarly Communications in the Light of the Digital Transition research project1) was a study which investigated the behaviours and attitudes of academic researchers as producers and consumers of scholarly information resources in respect to how they determine authority and trustworthiness. The research questions for the study arose out of CIBER's studies of the virtual scholar. This paper focuses on elements of this study, mainly an analysis of a scholarly publisher's usage logs, which was undertaken at the start of the project in order to build an evidence base, which would help calibrate the main methodological tools used by the project: interviews and questionnaire. The specific purpose of the log study was to identify and assess the digital usage behaviours that potentially raise trustworthiness and authority questions. Results from the self-report part of the study were additionally used to explain the logs. The main findings were that: 1) logs provide a good indicator of use and information seeking behaviour, albeit in respect to just a part of the information seeking journey; 2) the 'lite' form of information seeking behaviour observed in the logs is a sign of users trying to make their mind up in the face of a tsunami of information as to what is relevant and to be trusted; 3) Google and Google Scholar are the discovery platforms of choice for academic researchers, which partly points to the fact that they are influenced in what they use and read by ease of access; 4) usage is not a suitable proxy for quality. The paper also provides contextual data from CIBER's previous studies.

  • 본 논문에서는 Sentence-BERT 모델을 활용한 법률 문서 검색 방법을 제안한다. 법률 검색 서비스를 이용하고자 하는 일반인들은 법률 용어 및 구조에 대한 이해가 부족함에 따라 관련 판례 검색 등에 있어 어려움을 겪고 있다. 기존의 키워드 및 텍스트마이닝 기반 법률 검색 방법은 판결문의 문맥에 대한 정보가 없으며, 동음이의어 및 다의어에 대해 구분하기 어려워 성능을 높이는 데 한계가 있었다. 그로 인해 법률 문서 검색 결과에 대한 정확도가 낮아 신뢰하기가 어려웠다. 이를 위해, 대법원 판례 및 법률구조공단 상담사례 데이터에서 일반인의 법률 검색 문장에 대한 성능을 개선하고자 한다. Sentence-BERT 모델은 판례 및 상담 데이터에 대한 문맥 정보가 임베딩 되므로, 문장의 의미 손실이 적어 TF-IDF 및 Doc2Vec 검색 방법과 비교했을 때보다 검색 정확도가 개선된 것을 확인할 수 있었다.

  • 본 연구는 전거레코드 구축 및 공유를 위한 목적으로 진행된 'Social Networks and Archival Context' 프로젝트 사례를 통해 문화유산기관 간에 분산 소장된 역사적 정보원에 대한 통합적 접근과 기록에 대한 보다 풍부한 검색과 이해를 촉진하는 국가적 전거데이터베이스 구축의 필요성과 국내 적용 방안을 제시하였다. SNAC 프로젝트는 NARA 주도의 국제적 협력체 조직으로 전환되면서 지속가능한 운영체계를 확보하고 협력적 전거통제를 실현할 수 있었다. 또한 SNAC 전거레코드는 도서관에 비해 풍부한 생애와 역사에 관한 맥락 정보와 사회적·지적 네트워크 정보를 제공한다는 특징을 가진다. 사례분석을 통해 첫째, SNAC 처럼, 국가기록원이 주도하고 국립중앙도서관이 공동 오너쉽을 갖는 협력체가 개발을 주도하고 참여기관의 범위를 넓혀나가야 한다. 둘째, 협력의 방식에서 특장점을 가진 분야별로 분담하는 구조를 취하되, 두 기관이 참여하는 운영 주체가 주요한 의사결정을 하도록 한다. 셋째, 전거데이터 구축 시 다양한 포맷의 기술정보를 수집할 수 있는 확장가능한 오픈소스소프트웨어 개발, 기록관리 전거레코드의 구조와 요소로 설계, 전거레코드의 품질을 통제할 수 있는 기능 설계, 이용자 친화적 인터페이스 구축 및 콘텐츠적 요소가 반영된 플랫폼 설계가 필요함을 제시하였다.

  • Firms have reexamined and restructured their supply chain based on a long-term and partnership perspective as a firm's competitive advantage increasingly relies on its supply chain capability. A number of scholar works has provided evidence to support the positive effects of supply chain collaboration; however, the relationship between collaboration and performance is still inconclusive. This study refuses to have blinded faith on supply chain collaboration, but rather this paper suggests that the contribution of collaboration to supply chain performance improvement can be limited and vary along the contextual characteristics of a buyer-supplier relationship. Moreover, we argue that the relationship between supply chain collaboration and performance can be curvilinear. This paper provides and test hypotheses regarding the relationship between supply chain collaboration and performance. By using data of the Manufacturing Panel Survey (MPS), this study empirically validates the hypotheses. Overall, the results of the study support our hypotheses about a limited contribution of supply chain collaboration to manufacturing performance, which is opposite to a conventional expectation. Particularly, the effects of supply chain collaboration differ depending on the dimensions of performance such as customer satisfaction, quality, cost, delivery, and flexibility as well as the dependency in the buyer-supplier relationship. Moreover, the results of the study indicate that supply chain collaboration and performance may have curvilinear relationships in a certain context. Through a comprehensive model and empirical evidence, this study presents a better understanding of supply chain collaboration and provokes an open discussion about the effects of collaboration. This study also provides insightful implications for managers of buyers as well as suppliers who wish to foster stronger supply chain performance via a deep buyer-supplier relationship and collaboration.

  • Purpose: The purpose of this study was to systematically review and conduct meta-analysis on factors affecting career preparation behavior of Korean nursing students. Methods: Related articles published in Korean and English were collected based on search terms and converted into a numerical database. Data extraction, quality assessment and analysis including a systematic review and meta-analysis were completed. Results: The review included 27 studies. There were 25 factors influencing career preparation behavior of Korean nursing students. Factors were categorized into four sub-factors: personal, contextual, cognitive-emotional, and goal-related. In the meta-analysis of 27 articles the total effect size (ESr) was .34. The effect sizes of the four sub-factors were .37 for individual factors, .25 for situation factors, .34 for cognitive and emotional factors, and .41 for target factors. The main factors were .53 for career-related efficacy, .43 for self-leadership, and .43 for career decision level. Conclusion: Nursing students with high career-related efficacy and self-leadership are more likely to demonstrate career preparation behavior. Based on these results, educational institutions for nursing students must improve students' self-leadership and career effectiveness through education so that they can set career goals.

  • This review aimed to identify risk factors for occupational accidents and illnesses among young workers in the Nordic countries and to attain knowledge on specific vulnerable groups within the young working force that may need special attention. We conducted a systematic review from 1994 to 2014 using five online databases. Of the 12,528 retrieved articles, 54 met the review criteria and were quality assessed, in which data were extracted focusing on identifying occupational safety, health risk factors, and vulnerable groups among the young workers. The review shows that mechanical factors such as heavy lifting, psychosocial factors such as low control over work pace, and organizational factors such as safety climate are all associated with increased injury risk for young Nordic workers. Results show that exposures to chemical substances were associated with skin reactions, e.g., hand eczema. Heavy lifting and awkward postures were risk factors for low back pain, and high job demands were risk factors for mental health outcomes. The review identified young unskilled workers including school drop-out workers as particularly vulnerable groups when it comes to occupational accidents. In addition, apprentices and young skilled workers were found to be vulnerable to work-related illnesses. It is essential to avoid stereotyping young Nordic workers into one group using only age as a factor, as young workers are a heterogeneous group and their vulnerabilities to occupational safety and health risks are contextual. Politicians, researchers, and practitioners should account for this complexity in the education, training and organization of work, and workplace health and safety culture.
