As a famous herbal medicine in China and Asia, ginseng (Panax ginseng C. A. Meyer) is also known as the "King of All Herbs" and has long been used in medicine and healthcare. In addition to the obvious biological activities of ginsenosides, ginseng polysaccharides (GPs) exhibit excellent antitumor, antioxidant stress, and immunomodulatory effects. In particular, GPs can exert an antitumor effect and is a potential immunomodulator. However, due to the complexity and diversity in the structures and components of GPs, their specific physicochemical properties, and underlying mechanisms remain unclear. In this article, we have summarized the factors influencing the antitumor activity of GPs and their mechanism of action, including the stimulation of the immune system, regulation of the gut microbiota, and direct action on tumor cells

The purpose of the study is to analyze the main approaches to assessing human capital and develop proposals for its most objective assessment of it at the different levels of manifestation - individual, microeconomic and macroeconomic. The article considers the basic approaches to the evaluation of human capital, used in practice: retrospective (costly) and prospective (income based). Cost based methods involve measuring the value of human capital based on the total costs associated with its formation. The proposed additional evaluation criteria, in particular, the use of the expert approach and the developed indicators of a qualitative assessment of the human capital of the enterprise will allow development that is more efficient and use of available human resources. Human capital is becoming a major factor in the formation and development of an innovative economy and knowledge economy. Accordingly, the proposed additions to the assessment of human capital at the country level are aimed at assessing it from a new angle, taking into account the current global trends in the formation of an innovative economy and digitalization. They meet qualitatively new requirements for human capital as the main productive factor in the creation of new highly efficient technologies that promote the active development of the social sphere, science, education, health, etc.

Purpose : This study aimed to present evidence by analyzing the characteristics and effectiveness of group art therapy interventions through an examination of domestic studies on group art therapy for older people with dementia. Methods : The database used DBpia, Riss, and Google Scholar, and the research period was from 2016 to November 2021. For the selected studies, the level of evidence was analyzed, bias evaluation was performed, and patient, intervention, comparison, and outcome were analyzed. For the evaluation of bias, the risk of bias assessment tool for non-randomized study (RoBANS) and Cochrane's risk of bias (RoB) were used. Results : As for the level of evidence of the included studies, level I consisted of five studies, and levels II and III each had one article. As a result of the bias evaluation of five studies through RoB, a "low risk of bias" was found for incomplete result data, selective result reporting, and others, except for four unclear evaluation areas. The "low risk of bias" ratio was 0~25 % in the evaluation of bias in two studies through RoBANS. For the evaluation tool, cognitive evaluation tool was used the most while mini-mental state examination-Korea was used the most frequently. For the intervention method, the most frequently used was group art therapy that employed recall in three studies, while collage, Korean painting, use of paper media, and procedural memory were used in each of the other studies. Each intervention was found to be significantly effective overall. Conclusion : This study provided clinical evidence by systematically reporting research on group art therapy for older people with dementia. In the future, it is necessary to check the effect of group art therapy on various areas other than cognition for older people with dementia. Moreover, the study should be conducted with the risk of bias sufficiently taken into consideration.

Needs for public healthcare have recently increased. This paper proposes education topics for competency development in public healthcare in line with the needs of the times. In Korea, various lifelong education providers have already provided public health-related education. For example, the Research Institute for Health Policy (RIHP) under the Korean Medical Association provided an "executive course for physicians' public health care competencies" in 2019 and 2020. At the end of the course, the RIHP published a comprehensive report, entitled "Curricular development and evaluation for doctors' public healthcare competencies." This article is based on a summary of that report. To develop a curriculum for public healthcare, the RIHP adopted the following methodologies for a needs analysis; reviewing already-existing education subjects, evaluating end-of-course reports, and conducting in-depth focused group interviews and questionnaire surveys with doctors at public healthcare-related institutions. The results from the needs analysis can be categorized into two domains of education topics for public healthcare. The first domain includes education subjects related to the theory and practice of public healthcare, as follows: a general overview, community or population health, organizational administration, planning and evaluation, budget and finance, responses to disasters such as infectious diseases, health policy, and the legal system. The second domain contained education topics related to general professional competencies: leadership, communication, cooperation, teamwork, and professionalism. In conclusion, the curricular content for public healthcare will be an appropriate combination of competencies specific to public healthcare and core competencies for health professionals.

검색 시스템들의 평가를 위해 국내에서도 테스트 컬렉션에 관한 여러 연구가 진행되어왔다. 그러나 그 규모나 대상 분야가 편중되어 있고 질의 및 문헌 특성의 균형 등에 대한 고려가 반영되어 있지 않아 평가 결과를 객관화하기는 사실상 어려운 실정이다. 본 논문에서는 분야별, 사용자별 균형을 고려한 대규모 테스트 컬렉션인 HANTEC에 대해 기술한다. HANTEC 테스트 컬렉션은 총 12만 건의 문헌집합으로 구성되었는데 일반, 사회과학, 과학기술 각 분야별 4만 건씩으로 특정 분야에 편중되지 않도록 하였고 질의집합도 각 분야별 10개씩 30개로 구성하였다.

과학적 연구 방법은 가설을 세우고 실험이나 관찰을 통해 얻은 자료를 이용한 경험적 사실을 바탕으로 가설을 추상화하는 과정을 거치게 된다. 이 과정에서 자료를 획득하는 방법이 추상화의 최초 과정이 되고 많은 경우 서베이 리서치라는 구조화된 문항을 통한 방법이 사용 된다. 자료가 획득된 후에는 회귀분석, 선형구조방정식 등 고급 통계 기법들을 사용하여 가설들을 추상화하는 과정을 거치게 된다. 여기서, 설문지를 통해 많은 수 의 문항들의 응답이 획득되고 추상화를 위해 차원 축소라는 과정을 거치게 된다. 하지만 차원 축소된 정보들이 때때로 실제 현상을 이해하는데 있어서 현실감을 떨어지게 하는 경우도 존재하고 추상화 보다는 설문지 자체에서 어떤 지식을 얻기가 요구되기도 한다. 본 연구에서 설문지의 문항들 중에서 과연 어떤 문항들이 연구하고자 하는 문제의 해답을 줄 수 있는 핵심적인 문항인지를 찾아내고 이들 핵심 문항들로 모델을 구축하는 방법을 제시하였다. 강의 평가 자료를 예제로 사용하여 보다 나은 강의 평가를 받기 위한 전략들을 구상하여 보았다.

In order to considerably reduce the ambiguity rate, we propose in this article a disambiguation approach that is based on the selection of the right diacritics at different analysis levels. This hybrid approach combines a linguistic approach with a multi-criteria decision one and could be considered as an alternative choice to solve the morpho-lexical ambiguity problem regardless of the diacritics rate of the processed text. As to its evaluation, we tried the disambiguation on the online Alkhalil morphological analyzer (the proposed approach can be used on any morphological analyzer of the Arabic language) and obtained encouraging results with an F-measure of more than 80%.

In this article, the multiphysics response of magneto-electro-elastic (MEE) cantilever beam subjected to thermo-mechanical loading is analysed. The equilibrium equations of the system are obtained with the aid of the principle of total potential energy. The constitutive equations of a MEE material accounting the thermal fields are used for analysis. The corresponding finite element (FE) formulation is derived and model of the beam is generated using an eight noded 3D brick element. The 3D FE formulation developed enables the representation of governing equations in all three axes, achieving accurate results. Also, geometric, constitutive and loading assumptions required to dimensionality reduction can be avoided. Numerical evaluation is performed on the basis of the derived formulation and the influence of various mechanical loading profiles and volume fractions on the direct quantities and stresses is evaluated. In addition, an attempt has been made to compare the individual effect of thermal and mechanical loading with the combined effect. It is believed that the numerical results obtained helps in accurate design and development of sensors and actuators.

Disturbances in memory are the most common problem in patients with an organic mental syndrome. Other patients with significant psychiatric disorders also often have difficulty with memory. So it is very important in the clinical practice of psychiatry to understand the biological and neurocognitive mechanisms of memory proessing, and to develop the assessment tools with which memory function can be evaluated reliably and validly. Moreover, memory researches provide an important viewpoint from which we can understand the pathophysiological mechanisms of major neuropsychiatric illnesses. This article focuses on our understanding of memory functions in clinical and neurobiological aspects. The relevant material will be presented in four parts : 1) terminologies needed in defining major stages of various types of memory processing : 2) neurochemical and neuroanatomical basis of memory processing : 3) brief bed-side screening tests and more comprehensive neuropsychological tests for the evaluation of memory function : 4) the characteristics of memory dysfunction in several major psychiatric illnesses.
