창업역량은 기업가정신 연구의 핵심 개념이지만, 이에 대한 정의와 구성개념에 대한 학술적 합의는 부족한 실정이다. 우리 연구는 창업역량의 개념적ž조작적 정의를 체계적 으로 도출하고, 이 개념을 구성하는 하위요소 간 상대적 중요도를 조사하고자 한다. 이를 위해, 가추법적(abductive) 추론 과정으로 전문가 심층인터뷰, 델파이 조사(Delphi method), 계층구조 분석(Analytic Hierarchy Process)을 수행했다. 연구 결과, 6개의 창업역량 구성개념(재무관리, 디지털마케팅, 학습, 직원관리, 기회지향성, 고객지향성)과 36개의 측정 문항이 도출되었다. 또한, 창업역량 중 재무관리와 디지털마케팅 역량이 상대적으로 중요하고 기회지향성과 고객 지향성은 비교적 낮은 가중치를 갖는 것으로 나타났다. 이러한 연구 결과는 창업역량-경영성과 관계성 연구, 신생의 불리함 연구 등에 이론적 시사점을 제시하고, 예비창업자에게 창업역량 진단도구의 형태로 실용적 기여를 할 수 있다.
Stroke is one of the most common disabilities experienced by the elderly in the community. However, stroke progresses to a chronic level, patients are discharged from medical institutions and eventually no longer receive therapeutic interventions at home. In this systematic review, we compared home-based rehabilitation (HBR) with comparison for patients with stroke. Literature published in Cumulative Index for Nursing and Allied Health Literature (CINAHL), Embase, Physiotherapy Evidence Database (PEDro), PubMed, and Google Scholar were reviewed. A total of 1,158 studies were initially retrieved. After reading the full texts, 11 articles were included in the systematic review. Quality assessment of the included studies was conducted using Risk of Bias (RoB) 2.0, and Egger’s regression test was used to evaluate publication bias. Data analysis was performed using the R studio software (R Studio). According to the quality assessment using RoB 2.0, three studies were evaluated as low risk, two as of some concern, and three as high risk. The overall effect size was moderate (0.309). The value of the balance function was a small effect size (0.201), while the value of the gait function was a moderate effect size (0.353). The values were small and moderate effect (0.154, 0.411) for the chronic and subacute conditions, respectively. According to the Egger’s regression test, no publication bias was observed. The findings of this study indicate that HBR resulted in the greatest improvement in gait function in patients with subacute stroke compared to those with chronic stroke. Therefore, the application of this intervention to patients with stroke in the community is recommended.
Obesity is the cause of many diseases, and its severity continues to increase. Promoting non-shivering thermogenesis is attracting attention as a new treatment strategy for obesity. This study summarized the studies that evaluated the effect of Panax ginseng on promoting non-shivering thermogenesis in animal models. A total of 7 studies were included according to the selection criteria, of which five were judged to have a high risk of bias. Indicators of UCP1 mRNA, UCP1 protein, and PGC- 1a were used in the meta-analysis, and the certainty of evidence progressed for each indicator, with UCP1 protein showing the highest certainty of evidence. Meta-analysis was conducted on 5 works of literature with standard indicators. As a result of meta-analysis, UCP1 protein level and PGC-1a mRNA level were significantly increased statistically. In addition, the protein levels of PRDM16 and TFAM increased in several studies (not a meta-analysis). These findings suggest that Panax ginseng could be a potential therapeutic agent for obesity. However, further research is needed to understand its mechanisms and possible side effects fully. Thus, it is concluded that Panax ginseng in animal models can promote non-shivering thermogenesis and improve mitochondria function in animal models, opening up new avenues for research and potential clinical applications.
This study presents a systematic causal analysis of the fuel consumption rate reduction phenomenon observed in mortar-carrier tracked vehicles during driving tests. The investigation focused on identifying the root causes and developing effective improvement measures. Through comprehensive inspections and tests of the chassis and power pack components, along with data analysis, the study identified the damage of the engine flywheel housing gasket and the clogging of the transmission exhaust pump strainer as the main causes of the reduced fuel consumption rate. The causal relationship between the two phenomena was empirically proven using material composition analysis and statistical techniques, enhancing the reliability and validity of the diagnosis. Based on the root cause analysis results, improvements were implemented, including the replacement of the engine gasket and the cleaning of the transmission exhaust pump strainer. The effectiveness of the improvements was quantitatively verified, confirming a significant enhancement in fuel consumption rate and cruising range. By employing a systematic and scientific analysis methodology, this study provides a foundation for improving the reliability and maintenance efficiency of similar weapon systems and power transmission systems in general.
Background: Mobilization with movement (MWM) is an effective intervention for increasing range of motion (ROM) and function without pain. Objectives: The purpose of this study is to comprehensively characterize the functional effects of MWM applied to the ankle joint in patients with stroke. Design: Systematic Review and Meta-analysis. Methods: International electronic databases, CINAHL, Embase, MEDLINE, PubMed, and Google scholar were included and identified after review by two investigators in July 2023 according to PRISMA guidelines. Data were synthesized using software provided by Cochran and analyzed using a random effects model with reweighting to account for heterogeneity between participants. Results: After excluding duplicate studies, 14 of the 19 articles screened through the abstracts were excluded, resulting in a total of five studies involving 109 participants with stroke. MWM showed significant differences in ankle ROM [overall effect (Z=3.27, P=0.00)], gait speed [overall effect (Z=3.33, P=0.00)], and cadence [overall effect (Z=2.49, P=0.01)]. Conclusion: The results of the meta-analysis confirmed that MWM is effective in improving ankle ROM and gait parameters in patients with stroke.

Background: Kinesio taping (KT) is an intervention method used to improve early function after surgery; however, the effect of KT varies depending on the intervention method. Objectives: To investigated systematically review and quantitatively analyze the effect of KT randomized controlled trials (RCTs) applied to Total knee arthroplasty (TKA) to determine the value of the treatment method for TKA patients. Design: A systemic review and meta-analysis. Methods: Studies were identified by searching multiple electronic databases from January 2023 to February 2023. We selected RCTs comparing KT or no treatment, standard physical therapy, multimodal therapeutic approaches. When possible, we pooled data using random-effects meta-analysis. The Cochrane Bias Method Group's seven-item risk of bias (RoB) assessment tool was used for RCTs. The main outcomes were pain, swelling, and ROM. Results: Three trials (290 patients) provided sufficient data and were similar enough to be pooled for meta-analysis. The standardized mean difference for a reduction of pain was SMD = -1.02, 95 % CI -1.93 to -0.12; p= 0.03; I2= 92 %. The standardized mean difference for a reduction of swelling was SMD= - 0.23, 95 % CI -0.50 to -0.05; p= 0.10; I2= 58 %. The standardized mean difference for ROM was SMD= 1.06, 95 % CI -0.08 to 2.20; p= 0.07; I2= 95 %. Conclusion: KT has a large effect on pain reduction in TKA patients and could be used as an additional treatment option, but a small effect was observed in swelling and ROM.

Background: Research has been conducted on pain neuroscience education (PNE) for the relief of pain and symptoms associated with chronic neck pain (CNP). Focusing on the neurophysiology and neurobiology of chronic pain, pain processing, and particularly the function of the central nervous system for chronic pain, PNE helps patients to understand the causes of pain.
Objectives: To investigate and systematically review interventional studies on the effectiveness of PNE for patients with CNP and to analyze the effect size by performing a meta-analysis.
Design: A systematic review and meta-analysis protocol.
Methods: The following databases and electronic collections will be searched for primary studies without time limits: PubMed, MEDLINE, OVID Embase, and CENTRAL in the Cochrane Library. Reference lists from identified studies will be manually hand-searched for additional relevant works. Patients 18 years of age and older with nonspecific neck pain lasting 3 months or longer will be included in the study, with exclusion criteria as follows: cancer pain, fractures of the spine or surgical intervention, cognitive impairment that does not allow the patient to follow the PNE program, pregnancy, chronic fatigue syndrome, fibromyalgia, and other related pathologies that may prevent full participation in the PNE program. There are no geographic restrictions; however, non- English studies will be excluded.
Discussion: This study aims to evaluate the effects of PNE on pain and disability in chronic neck pain. Its results will help clarify whether the use of PNE alone can improve chronic pain. The advantages of systematic reviews include clear definitions and inclusion and exclusion criteria, standardized search formats, and objective independent reviews.
Failure to comply with the performance test requirements for the centrifugal pumps at power plants often results in performance dissatisfaction as a result of field tests. This study proposed a method of reducing the uncertainty of the field test results by evaluating the systematic error in the measurement system caused by failure to follow the test requirements using the computational fluid dynamics(CFD) technique. As a result of the evaluation of the systematic error and reflecting it in the performance test data, it was confirmed that the error occurred at a constant rate with respect to the flowrate and that the pump, which showed a difference in performance actually had the same performance.

This systematic review and meta-analysis aimed to determine whether food intake is effective in preventing diseases related to cognitive impairment. We searched English databases namely MEDLINE, PubMed and ScienceDirect from 2000 to May 2020, and Korean databases namely RISS, KISS, and DBPIA from 1990 to May 2020. We divided the data into 15 groups using the food group classification of the Korean Nutrition Society (KNS). The effect size (Cohen’s d) was estimated using a random-effect model, and a 95% confidence interval was calculated for each study. We included 17 cross-sectional studies and 7 cohort studies which involved 45,115 participants. As a result of analyzing the subgroups in the Asian population of both sexes, it was observed that grain intake has a protective effect against cognitive impairment. For females, pulses and fish also have a protective role against cognitive impairment. In the case of seaweed, a negative relationship was found with a moderate protective effect against cognitive impairment (Cohen’s d:-0.533, 95% CI: -0.939, -0.126; p=0.010) in Korean studies. Dairy products are associated with an increased risk of cognitive impairment in the American and European population but drinking alcohol is associated with a lower impairment risk. These results provide a basis for formulating the dietary guidelines for preventing dementia for each country.
The purpose of this study was to select 30 representative Korean dishes by a systematic review of preferences and recognition of Korean foods. The papers for the review were located using the keywords ‘hansik’, ‘hanguk eumsik’ from DBpia, KISS, NDSL and RISS, and 18 relevant papers were finally short-listed. To analyze the preferences of Koreans and foreigners for Korean dishes, respondents were chosen from various regions such as Asia, Europe, South Pacific, Africa, and North/South America. A total of 4,053 respondents participated in the selected papers and Korean dishes were classified according to the content analysis based on books published by the Rural Development Administration (RDA). Among the main dishes, two kinds of cooked rice were selected, bibimbap and kimbap. Also, noodles, dumplings, and sliced rice cake soup varieties mul-naengmyeon, guksujangguk, mandu, and tteokguk were selected as main dishes. The side dishes selected included 6 kinds of soup, miyeokguk, yukgaejang, samgyetang, gomtang, seolleongtang, and galbi-tang. Other side dishes selected were six types of stews namely doenjang-jjigae, kimchi-jjigae, sundubu-jjigae, haemultang, maeuntang, and dakbokkeum- tang. Three kinds of grilled side dishes selected were bulgogi, galbi-gui, and samgyeopsal-gui. Galbi-jjim was selected in the category of braised or steamed foods. Tteokbokki and japchae were the stir-fried food selected. Pan-fried foods and fried foods selected included a kind of haemul-pajeon and dak-gangjeong respectively. Seasoned vegetables selected were samsaek-namul including gosari-namul, sigeumchi-namul and doraji-namul. Two kinds of baechukimchi and kkakdugi were selected as kimchies, and sikhye was selected in the category of beverages and teas. These results could be used as selection criteria in developing recipes for representative Korean menus.
