Objectives : This study is to investigate the current National Health Insurance Database cohort studies related to complications of Parkinson's Disease (PD) and suggest the design of Korean medical epidemiological studies of PD. Methods : Nationwide longitudinal studies of PD patients in South Korea were collected through Pubmed and the Korea Citation Index (KCI). We selected cohort studies that used the National Health Insurance Database in Korea and targeted Parkinson's disease patients. Studies published before February 2024 were categorized according to study designs. We examined variables and covariates, enroll dates and matching methods. Results : Of a total of 536 studies, 18 studies met the inclusion criteria. All studies used the National Health Insurance (NHI) Research Database and among them, 5 used sample data and one senior database. Studies can be classified into two types. 11 cohort studies were comparing PD patients and non-PD patients. Another type was 4 PD patients cohort studies. Most studies used two diagnostic codes (G20 and V124) for inclusion criteria. Enroll periods were from 2002 to 2017, and follow-up periods were from 7 to 14 years. 16 studies considered age and sex as covariates. 15 studies used the propensity score matching method to increase the level of causality. There was only one study related to the Korean medical treatment. Conclusion : In future cohort studies on Korean medical treatment, more attempts should be made to reveal the effect of the treatments on PD patients by defining inclusion criteria for patient groups, covariates, exposure variables, and assessment indicators more operatively.

The number of environment-related technologies has increased remarkably over the past two decades, as has the public's interest in effective resource use and ways to reduce the effects of global warming. Industries that are based on environment-related technologies are thus growing rapidly. Previous studies revealed that externalities derived from the population concentration in urban areas positively affect agglomerations of high-tech industries. Such externalities have been named the "knowledge spillover effect". The purposes of the present paper are to (1) give a thumbnail sketch of the locations of environment-related industries around the world, using the Organisation for Economic Co-operation and Development environment-related patent statistics, and (2) explicate the effects of the Marshall-Arrow-Romer (MAR) and Jacobs externalities, which result from population concentrations in urban areas, on the agglomeration of environment-related industries in Sweden. The analysis revealed that environment-related industries are located chiefly in urban areas across the globe, and that only the MAR externalities influenced positively on the agglomeration of these industries in Sweden.

This study investigates how the truth-related words in Korean, which were originally noun or adverb with 'truth' related meaning, can be used as discourse markers with the functions such as 'emphatic marker', 'attention getter', or 'hesitation marker', and it argues that such functions of the discourse markers are the result of grammaticalization process. That is to say that the truth-related words have acquired new functions as discourse markers from their corresponding lexical items as a noun or an adverb through grammaticalization process. In this study, we demonstrate that the truth-related words tend to appear sentence-initially or sentence-medially when they are used as discourse markers. We also show that they are most likely to be used as emphatic marker because of the lexical meaning of the truth-related words. Finally, we state that truth-related words differ from one another in where they appear and what function they are used with.

The purpose of this study was to review the current studies on community attachment and its related variables to suggest directions for community attachment studies in Korea. Specific objectives of the study were to search the current studies on community attachment, to search for the significant variables related to community attachment, and to draw implications for community development in Korea. The major findings of the study were as follows; 1) Current studies on community attachment used individual characteristic variables such as length of residence in the community, age, size of population and density as major independent variables. 2) Studies on community attachment used community participation, social and cultural environment as major dependent variables, however, both independent variables and dependent variables were used interchangeably in many cases. 3) Recent studied on community attachment employed community economic and cultural variables, however, studies on community attachment in Korea was relatively limited in terms of quantity as well as quality. 4) Further research on community attachment should be conducted by utilizing various independent and dependent variables in various communities to increase the community attachment in rural and urban communities to further strengthen community development in Korea.

Purpose: The purpose of this study was to analyze intervention studies related to Snoezelen (multisensory environment). Methods: Studies related to Snoezelen (multisensory environment) published between 1995 and 2010 in both Korean and International journals were systematically reviewed, and analyzed following guidelines. Based on inclusion criteria, 23 studies including 5 Korean and 18 International articles were selected. Results: Most studies were conducted in various area of research such as medicine, nursing, and occupational therapy. There was no publication related to Snoezelen (multisensory environment) in Korean nursing journals. In terms of target population, more than 65 % of the study subjects were patients with dementia, mental retardation, and learning disability. Intervention was implemented mostly in less than 30 minutes, once a week for 2 to 4 weeks. The effects on behavior, physical, and psychological contexts were assessed as outcome indicators. There was more 'positive' than 'no effect' in self-stimulatory behaviors, problem behaviors, heart rate, pain, mood state, and anxiety, whereas more 'no effect' than 'positive' in blood pressure, respiration, enjoyment, and relaxation. Conclusion: Future studies are needed to develop the protocol and outcome indicators for effective use of this new intervention in Korea.

In this study, we collected and analyzed domestic and international studies related to watersheds in the forest sector. Keyword co-occurrence analysis was conducted using the VOSviewer program to identify the research areas of domestic and international studies and the network structure to compare research trends. As a result, the number of research articles in international watershed-related studies showed an overall increasing trend, and the research areas were diverse and located close to each other, indicating that many convergence studies were conducted. On the other hand, the number of papers in domestic watershed-related studies seems to have stagnated overall from the past to the present, and the research areas are mainly focused on forest disasters and hydrology, with limited interdisciplinary convergence studies. In addition, in both domestic and international studies, watersheds are currently mentioned as research sites rather than management or analysis units in the forest sector. It is important to actively promote interdisciplinary research in Korea to provide a scientific and balanced basis for watershed-level forest management planning.

Purpose: This study investigated how interprofessional education (IPE) related to medication for undergraduate healthcare students, including nursing students, has been designed and conducted. Furthermore, the outcomes of these IPE programs were evaluated. Methods: A scoping review was performed to understand the content and methods of IPE on medication for undergraduate healthcare students, including nursing students. A literature search was done using PubMed, Cumulative Index to Nursing and Allied Health Literature, Embase, Research Information Sharing Service, and Korean Nursing Database in English between January 2000 and December 2022. In total, 14 papers were selected and reviewed. Results: Eleven research studies were conducted on the implementation of one-time IPE on medication safety or errors. Among them, six studies focused on providing IPE to nursing students alongside medical and pharmacy students, while three studies targeted nursing and medical students, and two studies focused on nursing and pharmacy students. The most commonly employed educational method was simulation, which was utilized in 12 studies. All studies consistently reported a positive impact on attitudes toward IPE and effective communication. Additionally, five studies evaluating medication knowledge reported improvements in participants' understanding of drugs. Conclusion: The effects of IPE related to medication for undergraduate nursing students have been confirmed. It is necessary to introduce IPE in the field of pharmacology.

The goal of this study is to investigate domestic research trend on research data study. To achieve this goal, articles related research data topic were collected from RISS. After data cleansing, 134 author keywords were extracted from a total of 58 articles and keyword network analysis was performed. As a result, first, the number of studies related to research data in Korea is still only 58, so it was found that many related studies need to be conducted in the future. Second, most research fields related to research data were focused on library and information science among complex studies. Third, as a result of frequency analysis of author keywords related to research data, 'research data management', 'research data sharing', 'data repository', and 'open science' were analyzed as major frequent keywords, so research data-related research focuses on the above keywords. The keyword network analysis results also showed that high-frequency keywords occupy a central position in degree centrality and betweenness centrality and are located as core keywords in related studies. Through the results of this study, we were able to identify trends related to recent research data and identify areas that require intensive research in the future.

Objectives: Eight constitution medicine (ECM), which was first introduced in 1965, has been further developed and refined over the decades, and has consolidated its foundation through many studies on theories, diagnosis and clinical application. However, there have been few reviews on dissertations of ECM. In this study, we reviewed previously published studies related to ECM. Methods: We reviewed a total of 55 ECM-related studies published from 1965 to 2010 found on PubMed and various domestic Oriental medicine journals. Each thesis was classified as a theoretical, diagnostic, or remedy-related study. Results: 1. In the review of theoretical studies, shortly after ECM's introduction in 1965 by Kwon, the authors found studies on constitutional diseases, diets and food table which helped establish the background of ECM. ECM has further developed by comparing its theories with Sasang constitutional medicine, Huang-di-nei-jing, Saam, and Taegeuk acupuncture theories. 2. Research on diagnosis has been focused on its objectivity and accuracy. Constitution could be diagnosed by pulse-taking. To compensate for the lack of accuracy innate in pulse-taking, the Eight Constitution Questionnaire has been invented. 3. Remedies can be largely divided into acupuncture and diet. There were case studies comparing treatment effect of ECM acupuncture to other treatments. Diet related studies were carried out in the fields of immunology and nutrition. Conclusions: The authors reviewed studies that contributed to improved understanding of theories and clinical implications of ECM. Although there were various approaches to its theoretical and clinical grounds, more clinical research is needed. There is also a need to evaluate the accuracy of the experts' diagnoses of the constitution. The relationship between the diet and constitution also needs further research.

Objectives: Despite its advantages, it is not yet common practice in Korea for researchers to investigate disease associations using spatio-temporal analyses. In this study, we aimed to review health-related epidemiological research using spatio-temporal analyses and to observe methodological trends. Methods: Health-related studies that applied spatial or spatio-temporal methods were identified using 2 international databases (PubMed and Embase) and 4 Korean academic databases (KoreaMed, NDSL, DBpia, and RISS). Two reviewers extracted data to review the included studies. A search for relevant keywords yielded 5919 studies. Results: Of the studies that were initially found, 150 were ultimately included based on the eligibility criteria. In terms of the research topic, 5 categories with 11 subcategories were identified: chronic diseases (n=31, 20.7%), infectious diseases (n=27, 18.0%), health-related topics (including service utilization, equity, and behavior) (n=47, 31.3%), mental health (n=15, 10.0%), and cancer (n=7, 4.7%). Compared to the period between 2000 and 2010, more studies published between 2011 and 2020 were found to use 2 or more spatial analysis techniques (35.6% of included studies), and the number of studies on mapping increased 6-fold. Conclusions: Further spatio-temporal analysis-related studies with point data are needed to provide insights and evidence to support policy decision-making for the prevention and control of infectious and chronic diseases using advances in spatial techniques.
