Objectives: This study aimed to assess the clinical evidence supporting the use of acupuncture (AC) for premenstrual syndrome (PMS). Methods: We searched randomized controlled trials (RCTs) that used AC for PMS in 9 databases (PubMed, EMBASE, Cochrane Library, CINAHL, CNKI, CiNii, SCIENCE ON, KoreaMed, OASIS) from their inception to July 2022. Results: We identified 1,168 studies, of which 15 RCTs met the inclusion criteria. The risk of bias in the included studies was relatively unclear or high. Meta-analysis of 3 RCTs showed that the AC group had a significantly higher effective rate than the Medroxyprogesterone group (RR 1.48, 95% CI (1.23, 1.78), p<0.0001). Meta-analysis of 2 RCTs showed that there was no statistically significant difference between the AC group and the Sham AC group in the effective rate (RR 4.72, 95% CI (0.88, 25.36), p=0.07). In a review of individual studies, the AC group was more effective than the control group in terms of the effective rate, symptom scale, quality of life, adverse events, and recurrence rate. Conclusions: The AC group was more effective than general treatments groups such as sham AC, western medicine, and dietary supplements, and there were no serious adverse events. However, the evidence on the effectiveness and safety of acupuncture for PMS was inconclusive due to the small number of included studies and low quality. Therefore, systematic reviews based on more rigorously designed randomized clinical trials are needed in the future to properly evaluate the effect of AC on PMS.

Purpose: The aim of this study was to evaluate the effect of auriculotherapy on musculoskeletal pain in adults. Methods: A total of 885 studies were retrieved from nine databases (PubMed, Scopus, CINAHL, Web of Science, Ovid Medline, Cochrane Library, RISS, KMbase, and KISS). Sixteen studies were selected for meta-analysis, which satisfied the inclusion criteria and the evaluation of risk of bias. Demographic data, auriculotherapy types, intervention characteristics, auricular points, and outcomes related to pain (subjective pain scale, and amount of analgesic) were extracted from all included studies. The effect size of auriculotherapy was analyzed through comprehensive meta analysis 3.0, and the presence of publication bias was analyzed through a funnel plot and Egger's regression. Results: The results of the meta-analysis (n = 16) revealed that the auriculotherapy was significantly superior to the control group on present pain in adults (Hedges' g = - 0.35, 95% Confidence Interval [CI] = - 0.55~- 0.15). According to the results of subgroup analysis, the effect size of auricular acupuncture therapy (Hedges' g = 0.45, 95% CI = - 0.75~- 0.15) was higher than the auricular acupuncture (Hedges' g = 0.27, 95% CI = - 0.53~0.00): the longer the intervention period, the greater the effect size. Conclusion: In this study, auriculotherapy demonstrates a significant reduction in musculoskeletal pain in adults. Therefore, it is necessary to refine the curriculum to include auriculotherapy as a nursing intervention to relieve musculoskeletal pain in adults and encourage its use in clinical settings.

본 논문에서는 ADHD 진단을 해주는 전문가시스템을 설계 및 구현한다. DSM-IV-TR을 이용하여 ADHD 진단기준을 연령대에 따라 단어를 바꾸어 구체화한다. 이 진단지를 가지고 오브젝트와 해당 값을 설정하고 규칙을 생성한다. 그리고 'ADHD 진단 시스템 엔진'과 '사용자 질의응답 프로그램'으로 구성된 진단시스템을 설계한다. 'ADHD 진단 시스템 엔진'은 규칙 기반 추론 엔진으로 Prolog 언어로 구현하여, INPUT을 '사용자 질의응답 프로그램'으로부터 받는다. INPUT에 의해 규칙은 ADHD 진단기준을 기반으로 점화되며 진단결과를 추론해서 OUTPUT을 다시 '사용자 질의응답 프로그램'으로 보낸다. '사용자 질의응답 프로그램'은 Python 언어로 구현하여 사용자와의 대화를 처리하는 인터페이스 역할을 한다. 'ADHD 진단 시스템 엔진'과 '사용자 질의응답 프로그램'의 중간다리 역할을 Pyswip 라이브러리를 통해서 수행한다. 결과적으로 ADHD 진단 전문가시스템을 통해 진단비용 절감과 간편한 이용으로 치료계획에 도움을 주고자한다.

Issues relating to business inheritance are a primary focus for business owners. Business inheritance is critical to ensuring that the business can be managed by the next generation and family members can benefit from the earnings and revenues. Therefore, preliminary planning must be done while the business owner is still alive by selecting the appropriate business inheritance mechanism for Muslims in Malaysia. The mechanisms of business inheritance, notably faraid, hibah, amanah, and hibah amanah will be examined in this paper from both a civil and Islamic perspective. By reviewing written journals and previous research, this research utilizes the library method. According to this study, business succession can be carried out by naming a beneficiary as a partner in the company or by completing the ownership transfer process while the owner is still living. In the other situation, it can be done by anyone among the heirs agreeing to re-register the business as usual. Meanwhile, there are four main instruments in Islamic law that can be used: faraid, hibah, amanah, and commercial hibah. According to this study, each instrument has a different impact on business succession. Entrepreneurs should use these instruments in their firm succession planning.

Objectives: The aim of the present systematic review was to investigate the cryopreservation process of dental pulp mesenchymal stromal cells and whether cryopreservation is effective in promoting cell viability and recovery. Materials and Methods: This systematic review was developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and the research question was determined using the population, exposure, comparison, and outcomes strategy. Electronic searches were conducted in the PubMed, Cochrane Library, Science Direct, LILACS, and SciELO databases and in the gray literature (dissertations and thesis databases and Google Scholar) for relevant articles published up to March 2019. Clinical trial studies performed with dental pulp of human permanent or primary teeth, containing concrete information regarding the cryopreservation stages, and with cryopreservation performed for a period of at least 1 week were included in this study. Results: The search strategy resulted in the retrieval of 185 publications. After the application of the eligibility criteria, 21 articles were selected for a qualitative analysis. Conclusions: The cryopreservation process must be carried out in 6 stages: tooth disinfection, pulp extraction, cell isolation, cell proliferation, cryopreservation, and thawing. In addition, it can be inferred that the use of dimethyl sulfoxide, programmable freezing, and storage in liquid nitrogen are associated with a high rate of cell viability after thawing and a high rate of cell proliferation in both primary and permanent teeth.

Purpose : Sleep disturbances in patients in the intensive care unit (ICU) are related to health problems after discharge. Therefore, active prevention and management are required. Hence, identification of the factors that affect sleep in patients who are critically ill is necessary. Methods : The PubMed, Cochrane Library, CINAHL, EMBASE, and Web of Science databases were searched. Selection criteria were observational and experimental studies that assessed sleep as an outcome, included adult patients admitted to the ICU, and published between November 2015 and April 2022. Results : A total of 21,136 articles were identified through search engines and manual searches, and 42 articles were selected. From these, 22 influencing factors and 11 interventions were identified. Individual factors included disease severity, age, pain, delirium, comorbidities, alcohol consumption, sex, sleep disturbance before hospitalization, chronic obstructive pulmonary disease (COPD), cardiovascular disease, and high diastolic blood pressure (DBP), low hemoglobin (Hb), and low respiratory rate (RR). Environmental factors included light level, noise level, and temperature. Furthermore, treatment-related factors included use of sedatives, melatonin administration, sleep management guidelines, ventilator application, nursing treatment, and length of ICU stay. Regarding sleep interventions, massage, eye mask and earplugs, quiet time and multicomponent protocols, aromatherapy, acupressure, sounds of the sea, adaptive intervention, circulation lighting, and single occupation in a room were identified. Conclusion : Based on these results, we propose the development and application of various interventions to improve sleep quality in patients who are critically ill.

This review aimed to characterize the effect of direct restorative material types and adhesive protocols on marginal adaptation and the bond strength of the interface between the material and the proximal dentin/cementum. An electronic search of 3 databases (the National Library of Medicine [MEDLINE/PubMed], Scopus, and ScienceDirect) was conducted. Studies were included if they evaluated marginal adaptation or bond strength tests for proximal restorations under the cementoenamel junction. Only 16 studies met the inclusion criteria and were included in this review. These studies presented a high degree of heterogeneity in terms of the materials used and the methodologies and evaluation criteria of each test; therefore, only a descriptive analysis could be conducted. The included studies were individually evaluated for the risk of bias following predetermined criteria. To summarize the results of the included studies, the type of restorative material affected the test results, whereas the use of different adhesive protocols had an insignificant effect on the results. It could be concluded that various categories of resin-based composites could be a suitable choice for clinicians to elevate proximal dentin/cementum margins, rather than the open sandwich technique with resin-modified glass ionomers. Despite challenges in bonding to proximal dentin/cementum margins, different adhesive protocols provided comparable outcomes.
