  • This study concluded the results of a research on the features of cement based permeation grout, based on some important grout parameters, such as the rheological properties (yield stress and viscosity), coefficient of permeability to grout ($k_G$) and the inject ability of cement grout (N and $N_c$ assessment), which govern the performance of cement based permeation grouting in porous media. Due to the limited knowledge of these important grout parameters and other influencing factors (filtration pressure, rate and time of injection and the grout volume) used in the field work, the application of cement based permeation grouting is still largely a trial and error process in the current practice, especially in the local construction industry. It is seen possible to use simple formulas in order to select the injection parameters and to evaluate their inter-relationship, as well as to optimize injection spacing and times with respect to injection source dimensions and in-situ permeability. The validity of spherical and cylindrical flow model was not verified by any past research works covered in the literature review. Therefore, a theoretical investigation including grout flow models and significant grout parameters for the design of permeation grouting was conducted in this study. This two grout flow models were applied for three grout mixes prepared for w/c=0.75, w/c=1.00 and w/c=1.25 in this study. The relations between injection times, radius, pump pressure and flow rate for both flow models were investigated and the results were presented. Furthermore, in order to investigate these two flow model, some rheological properties of the grout mixes, particle size distribution of the cement used in this study and some geotechnical properties of the sand used in this work were defined and presented.

  • 본 연구는 로봇시스템화를 통한 병동 간호업무를 위한 방향에 대해 전망해 보고자 시도되었다. 지금까지 개발된 병동간호업무에 사용가능한 로봇시스템들은 작동의 어려움이나, 공간적 제약, 높은 가격으로 보편화되지 못했다. 병동 간호업무의 로봇시스템화는 가급적 환자와 접촉하는 시간 이외의 업무를 줄여주는데 단순하고 반복적인 업무의 로봇시스템화에 집중해야 할 것이다. 2인 인터뷰를 통해 활력징후측정에 대한 로봇시스템화와, 침상교환을 돕는 로봇시스템화에 대한 아이디어는 공학분야와 함께 논의해볼만 하다. 이에 병동내 간호업무의 로봇시스템화를 설계시 제한점들이 충분히 고려되어야 할 것이다. 그리고 성공적인 간호와 타학제간 융합을 위해 간호업무에 대한 세심한 직무분석이 필요하고, 융합의 시행착오 극복을 위해 간호학과 타학제간 융합학회를 설립할 필요가 있다. 성공적인 병동 간호업무의 로봇시스템화는 병원의 수익 창출 뿐 아니라 간호사의 위상을 높이고, 간호업무의 혁신을 일으키는 발단이 될 것이다.

  • The article examines the stage of verification of a crime report from the standpoint of the need for its legislative regulation. Moreover, it investigates the international experience in this field. The existing procedural models are described in detail on the example of the neighboring and faraway countries. An analysis of the provisions of the current criminal procedure law of Russia and foreign experience allowed the authors to identify existing problems in the implementation of departmental control and prosecutorial supervision at the stage of verifying a crime report. The aim of the study is to develop theoretical provisions and recommendations regarding the implementation of departmental procedural control and prosecutorial supervision over the activities of the investigator during the verification of reports of crimes, based on the study of experience, both in Russia and in a number of countries of the near and far abroad, which could find their reflection in law enforcement practice, as well as aimed at improving the current criminal procedure legislation. The authors substantiated the theory that a detailed examination of the foreign procedural foundations of checking a crime report will allow us to form the most suitable model for checking a crime report for our state, taking into account all possible features and successfully implement it into the current criminal procedural law of the Russian Federation.

  • We evaluated a worm-based extruded pellet diet with black soldier fly Hermetia illucens larvae (BSF) meal and BSF oil for olive flounder Paralichthys olivaceus through field feeding experiments at a commercial aquafarm. We prepared two experimental diets by replacing fish meal and fish oil with BSF meal and BSF oil (BEP-1, BSF meal 7%, BSF oil 1%) and (BEP-2, BSF oil 2%), respectively. We prepared raw-fish based moist pellets (MP) for comparison between the two experimental diets. We distributed the olive flounder (220±6.29 g) in square (10 m×10 m×1 m) concrete, 100 ton tanks at a density of 1,600 fish per tank (n=3) in triplicate for each dietary treatment. We fed the diets to the fish to apparent satiation for 7 months. At the end of the feeding trial, we found no substantial differences between the groups in terms of growth performance, survival, or feed utilization. None of the diet groups showed any changes in either hematological or non-specific immune responses. The histological observation of the intestine showed that the goblet cell number and cholecystokinin-producing cell activity increased in the fish fed the BEP diet compared with the those of the fish fed the MP diet. These results indicated that dietary BSF meal and oil can be used for olive flounder without compromising growth or, hematological and histological parameters.

  • The Randomized Control Trial (RCT) is the most well-established and widely used statistical methodology in clinical research; however, applying thorough RCT to cancer patients presents challenges such as ethical concerns, high costs, short clinical periods, and limitations in collecting various side effects. To address this issue, the propensity score matching method, which takes advantage of the benefits of observational research while compensating for the drawbacks of randomized control trials, is used in a variety of fields. In recent years, 28 studies on the effectiveness of Korean medicine on tumors have been conducted abroad using the Propensity Score Matching Method, but none have been conducted in Korea. The majority of studies have focused on liver cancer, colon cancer, lung cancer, and stomach cancer, with endpoints such as survival time, incidence rate, quality of life, and treatment outcomes revealing statistical differences in how Korean medicine intervention affects treatment outcomes. As a result, well-established studies using the propensity matching score methodology should be useful in evaluating the impact of Korean medicine in oncology treatments.

  • Pepper mild mottle virus (PMMoV), one of the most prevalent viruses in chili pepper (Capsicum annuum L.) is a non-enveloped, rod-shaped, single-stranded positive-sense RNA virus classified in the genus Tobamovirus. The supernatants of five bacterial cultures (Pseudomonas putida [PP], Bacillus licheniformis [BLI], P. fluorescens [PF], Serratia marcescens [SER], and B. amyloliquifaciens [BA]) were analyzed to find novel antiviral agents to PMMoV in chili pepper. Foliar spraying with supernatants (1:1, v/v) obtained from Luria-Bertani broth cultures of PP, BLI, PF, SER, and BA inhibited PMMoV infection of chili pepper if applied before the PMMoV inoculation. Double-antibody sandwich enzyme-linked immunosorbent assay showed that treatments of five supernatants resulted in 51-66% reductions in PMMoV accumulation in the treated chili pepper. To identify key compounds in supernatants of PP, BLI, PF, SER, and BA, the supernatants were subjected to gas chromatography-mass spectrometry. The 24 different types of compounds were identified from the supernatants of PP, BLI, PF, SER, and BA. The compounds vary from supernatants of one bacterial culture to another which includes simple compounds-alkanes, ketones, alcohols, and an aromatic ring containing compounds. The compounds triggered the inhibitory effect on PMMoV propagation in chili pepper plants. In conclusion, the cultures could be used to further conduct tissue culture and field trial experiments as potential bio-control agents.

  • Objectives: The aim of this study is to review and analyze the trends in prospective clinical research (PCR), project, clinical study protocol of Korean medicine (KM) for dementia. Methods: We searched PCRs of KM on dementia in six electronical databases, up to January 28, 2021. Moreover, the clinical research protocol and projects of KM for dementia were searched. Results: Total eight PCRs, nine projects, and three clinical study protocols were included. In the PCRs, there were one randomized controlled trial, five before and after study, and two comparative group before-after studies. Four of them used herbal medicine, two used acupuncture, one study used both herbal medicine and acupuncture, and the other one used moxibustion. Jowiseungchung-tang was the most frequently used herbal medicine. BL62, KI6 were used in electro-acupuncture, auricular-Shenmen in auricular acupuncture, and GV20 in moxibustion. The most frequent outcome was Korean-Dementia Rating Scale (K-DRS). One reported significant increase in K-DRS score, one reported 60% improvement, and the other studies mostly reported no significant difference. In the projects including 20 clinical studies of dementia, herbal medicine, integrative medicine and acupuncture were mainly used. In the protocols, herbal medicine, complex KM intervention, and integrative medicine were used. Conclusions: Currently, the number of PCRs of KM for dementia is very scarce. Therefore, the researcher's interest in this field and national research support should be made more, and the quality of clinical research in the future can be further improved by supplementing the limitations of previously published clinical research.
