Unstructured Data Analysis and Visualization “Korean Journal of Industrial and Organizational Psychology(2010~2017)”

빅데이터가 보급되면서 비정형자료 분석기술에 관한 관심이 증가하고 있으며, 방대한 양의 학술 데이터에서 가치 있는 정보를 도출해 내는 연구들이 수행되고 있다. 대부분 대용량 텍스트를 인간이 수동적으로 분석하는 것은 시간과 노력이 많이 들고 어려우므로 이를 보완하기 위해 자동으로 분류해줄 수 있는 기술이 필요하다. 이에 본 연구는 2010년부터 2017년까지 발간한 ‘한국심리학회지: 산업 및 조직’ 논문의 주요어, 논문제목, 초록과 같은 비정형자료를 이용하여 분석하고 시각화하였다. 연구결과는 다음과 같다. 첫째, 주요어를 워드클라우드로 시각화한 결과 ‘조직몰입’이 빈번히 사용되었으며, 직무만족, 직무열의, 이직의도, 정서노동 순으로 나타났다. 둘째, 논문제목과 초록을 LDA 확률에 근거하여 자동으로 10개의 주제로 분류하였으며, 주제 8(조직/몰입/지각)이 가장 높았고, 주제 5(행동/관리/상사)는 가장 낮았다. 셋째, 주저자와 교신저자와의 관계는 6개의 큰 집단과 다수의 작은 집단으로 나타났으며, 집단 내의 유력자를 알 수 있었다. 본 연구에서는 방대한 양의 학술 데이터에서 보다 빠르고 쉽게 정보를 도출하여 제공함으로써 관련 연구자들이 또 다른 연구에 접근할 수 있도록 도움을 줄 수 있다는데 의의를 둔다.

“Sport herstory”: The research trends and tasksin Korean women’s sport history, 2007~2016

[Purpose] This study aims to examine the research trends in Korean women’s sport history and provide suggestions for future research by reviewing journal articles conducted in the last ten years (2007-2016). [Methods] The articles were selected from the Korean Journal of History for Physical Education, Sport, and Dance, which is the only, representative sport history journal in South Korea. 66 articles identified as studies of women’s (or women-related) sport history were analyzed in five categories, including a) period, b) theme/topic, c) purpose, d) method, and e) country. [Results] Specifically, the analysis by period showed that 90% of the research focused on modern and contemporary history, while only 7% of the research was set in pre-modern history. According to the analysis by theme/topic, genre has been studied most often with 36%, followed by figure (20%) and facility/institution/organization (15%). By the criteria of purpose, it was found that the majority of the research (48%) focused on historical evolution and transition, while the research on comparison/relation was of little scholarly interest. Regarding the category of method, textual analysis was used most often, with 70% followed by oral life history (27%). By the criteria of country, the largest ratio of papers studied Korea (75%) while only 3% of studies examined other East Asian countries, such as China or Japan. Comparative, diasporic, or transnational studies were the second most popular subcategory (11%). [Conclusion] According to the results, it was acknowledged that there has been a significant lack of interest in women’s sport history by Korean scholars and “sport herstory” is largely underresearched. In addition, the excessive concentration on a specific period or a particular theme was also exposed. To rectify the biased research practice and promote scholarly growth and enhancement in both academia of Korean women’s sport history and Korean sport history, it is necessary to consider the expansion of historical materials, application of new methodology, cross-disciplinary conversation, and theorization in studying women’s sporting experiences.

This review summarizes the history of freshwater zooplankton research in Korean Society of Limnology and necessary future topics that are remain poorly investigated in South Korea based on main research topics of published articles focusing on lakes, reservoirs, rivers and wetland ecosystems. In Korea, a total 450 freshwater zooplankton species have been reported (85 species of cladocera, ca. 230 species of rotifera since 1939, and 138 species of copepoda), and they cover 10% of total zooplankton species list. In the present paper, we provide recent species list of zooplankton found in Korea and their taxonomic keys. Over periods of 45 years, there are 25 published papers for zooplankton biota in lentic ecosystems in Korean Journal of Ecology and Environment (KJEE). The ecology of zooplankton communities in rivers has focused on the mechanisms involved in regulating their abundance, diversity and spatio-temporal patterns of genus Bosmina and rotifers (genus Brachionus and Keratella) that are most frequently found from Korea. On the other hand, the studies on zooplankton in wetland has focused on Alona, Chydorus and Ceriodaphnia with special emphasis on their relationships with aquatic macrophytes. Even though studies on the freshwater ecosystem in Korea have a long history, a few of studies on zooplankton biota were conducted at rice paddy, Dumbeong and wetlands. During the last two decades, experimental advances in freshwater zooplankton ecology and understanding of structure and function of this biota were made from a series of articles mainly in journal of KJEE. For future studies, quantitative, experimental and interdisciplinary approaches would be key words to understand zooplankton ecology and their roles in aquatic ecosystems under changing environments, and we have suggested necessary zooplankton research fields and future directions.

Age of Data in Contemporary Research Articles Published in Representative General Radiology Journals.

ObjectiveTo analyze and compare the age of data in contemporary research articles published in representative general radiology journals.Materials and MethodsWe searched for articles reporting original research studies analyzing patient data that were published in the print issues of the Korean Journal of Radiology (KJR), European Radiology (ER), and Radiology in 2017. Eligible articles were reviewed to extract data collection period (time from first patient recruitment to last patient follow-up) and age of data (time between data collection end and publication). The journals were compared in terms of the proportion of articles reporting the data collection period to the level of calendar month and regarding the age of data.ResultsThere were 50, 492, and 254 eligible articles in KJR, ER, and Radiology, respectively. Of these, 44 (88%; 95% confidence interval [CI]: 75.8–94.8%), 359 (73%; 95% CI: 68.9–76.7%), and 211 (83.1%; 95% CI: 78–87.2%) articles, respectively, provided enough details of data collection period, revealing a significant difference between ER and Radiology (p = 0.002). The age of data was significantly greater in KJR (median age: 826 days; range: 299–2843 days) than in ER (median age: 570 days; range: 56–4742 days; p < 0.001) and Radiology (median age: 618; range: 75–4271 days; p < 0.001).ConclusionKorean Journal of Radiology did not fall behind ER or Radiology in reporting of data collection period, but showed a significantly greater age of data than ER and Radiology, suggesting that KJR should take measures to improve the timeliness of its data.

Trend Analysis of Research Articles Published in the Korean Journal of Women Health Nursing from 2013 to 2017.

To analyze articles published in the Korean Journal of Women Health Nursing from 2013 to 2017 to determine the latest research trends and understand how 2013 Korea Women's Health Statistics were reflected in journal articles. A total of 130 studies were analyzed. Research design, types of research, research framework, research subjects, characteristics of quantitative research, characteristics of qualitative research, and keywords were analyzed using a structured analysis format. Quantitative and qualitative research accounted for 83.8% and 13% of these 130 studies analyzed, respectively. Non-experimental and experimental research accounted for 70.7% and 13.1% of these studies, respectively. The most frequent study subjects were childbearing women (62.8%), including college students, mothers, and adults. A total of 69.1% of non-experimental research and 88.2% of experimental research used convenience sampling. Questionnaires were most frequently used for data collection. The most frequent keyword domain involved health-related concepts (41%) among nine domains and the most frequently used keyword was "women." This study suggest that further experimental research should be conducted in the future. Also, adolescent and the elderly women should be focused on as subjects in future studies based on results of 2013 Korean Women's Health Statistics.

Research Trend of Women's Health in Korean Nursing Journals (2010~2015).

To explore trends of women's health in nursing research by analyzing articles on women aged 13 years or older that were published in Korean Journal for Women Health Nursing from 2010 to 2015. Seven focus areas were identified and modified to reflect integrative conceptual models of women's health: maternity care, menstrual concerns, health problems in women, gender influences on health risks, social influences on women's health, women and health care policy, and sexual health and violence against women. A total of 383 studies were analyzed according to these seven focus areas. Health problems in women, maternity care, and societal influences on women's health were the most widely studied topics in Korean women's health. There was increased attention to societal influences on women's health and gender influences on health risk. However, these areas are still limited in nursing research. Only 1% of these studies were in area of women's health policy. More studies in area of sexual health and violence against women are needed. Studies in area of women and health care policy are also needed to improve women's health in Korea.

Laparoscopic vs open complete mesocolic excision with central vascular ligation for colon cancer: A systematic review and meta-analysis.

AIMTo compare the effectiveness of laparoscopic complete mesocolic excision (CME) with central vascular ligation (L-CME) with its open (O-CME) counterpart.METHODSWe conducted an electronic search of the PubMed/MEDLINE, Excerpta Medica Database, Web of Science Core Collection, Cochrane Center Register of Controlled Trails, Cochrane Database of Systematic Reviews, SciELO, and Korean Journal databases from their inception until May 2017. We considered randomized controlled trials (RCTs) and controlled clinical trials (CCTs) that included patients with colonic cancer comparing L-CME and O-CME. Primary outcomes included the quality of the resected specimen (lymph nodes retrieved, complete mesocolic plane excision, tumor to arterial high tie, resected mesocolon surface). Secondary outcomes included the three-year and five-year overall and disease-free survival rates, recurrence of the disease, surgical data, and postoperative morbidity and mortality. Two authors of the review screened the methodological quality of the eligible trials and independently extracted data from individual studies.RESULTSA total of one RCT and eleven CCTs (four from Europe and seven from Asia) met the inclusion criteria for the current meta-analysis. These studies involved 1619 patients in L-CME and 1477 patients in O-CME. The L-CME was associated with the same quality of the resected specimen, with no differences regarding the retrieved lymphnodes (MD = -1.06, 95%CI: -3.65 to 1.53, P = 0.42), and tumor to high tie distance (MD = 14.26 cm, 95%CI: -4.30 to 32.82, P = 0.13); the surface of the resected mesocolon was higher in the L-CME group (MD = 11.75 cm2, 95%CI: 9.50 to 13.99, P < 0.001). The L-CME was associated with a lower rate of blood transfusions (OR = 0.45, 95%CI: 0.27 to 0.75, P = 0.002), faster recovery of gastrointestinal function, and less postoperative overall complication rate. The L-CME approach was associated with a statistical significant better three-year overall (OR = 2.02, 95%CI: 1.31 to 3.12, P = 0.001, I2 = 28%) and disease-free (OR = 1.45, 95% CI: 1.00 to 2.10, P = 0.05, I2 = 0%) survival.CONCLUSIONThe laparoscopic approach offers the same quality of the resected specimen as the open approach in complete mesocolic excision with central vascular ligation for colon cancer. The laparoscopic complete mesocolic excision with central vascular ligation is superior in all perioperative results and at least non-inferior in long-term oncological outcomes.

Hawthorne effect reporting in orthodontic randomized controlled trials: truth or myth? Blessing or curse?

To investigate in 10 orthodontic journals how many randomized controlled trials (RCTs) considered the Hawthorne effect, and if considered, to determine whether it was related to the patients or the therapists involved in the trial and, finally, to discuss the Hawthorne effect in an educational way. A search was performed on the Medline database, via PubMed, for publication type 'randomized controlled trial' published for each journal between 1 August 2007 and 31 July 2017. The American Journal of Orthodontics and Dentofacial Orthopedics, Angle Orthodontist, Australian Orthodontic Journal, Dental Press Journal of Orthodontics, European Journal of Orthodontics, Journal of Orthodontics, Journal of Orofacial Orthopedics, Korean Journal of Orthodontics, Orthodontics and Craniofacial Research and Progress in Orthodontics were assessed. Two independent reviewers extracted the data and identified whether the Hawthorne effect was considered or discussed in the articles and whether the Hawthorne effect was related to the behaviour of the patients, the therapists, or both. The initial search generated 502 possible trials. After applying the inclusion and exclusion criteria, 290 RCTs were included and assessed. The Hawthorne effect was considered or discussed in 10 of 290 RCTs (3.4%), and all were related to the patients' and none to the therapists' behaviour. The Hawthorne effect reported in orthodontic RCTs was suboptimal. The researchers' lack of knowledge about this phenomenon is evident, despite evidence that the Hawthorne effect may cause over-optimistic results or false-positive bias.
