  • In recent years, the proportion of arable land in the nation has grown from 36.2 percent in 1990 to 43.7 percent in 2013. The study first performed the vulnerability assessment of agricultural production, transportation, processing facilities, agricultural machinery leasing facilities, and water supply facilities. It was developed for the evaluation of the vulnerability of each gun of garlic and onions based on the distance from the three groups of arable bodies to the facility and the processing capacity of facilities. In view of these regional imbalances, the store, distribution and processing facilities in the main stream were found in Haenam, South Jeolla-do, and the relatively low regions of the gun were located in Goheung-gun and Hampyeong-gun. Among other regions, agricultural machinery rental facilities were high in Changnyeong-gun, Haenam, and two regions, while the water supply facilities were high in the southern area of Haenam and South Jeolla-do. The Gyeongsang-do showed relatively high levels of comparison vulnerability index compared to Jeolla-do regions. In particular, through the management plan to improve the facilities needed to improve agricultural production infrastructure, it is necessary to increase the competitiveness of agricultural productuivity through the planning of the need for additional support through the rural readjustment project.

  • In this study, vinegar disinfection was evaluated as a novel method for the preparation of raw food ingredients used in foodservice operations. The test materials were washed and disinfected using three different methods, and were then stored at temperatures of $3^{\circ}C\;and\;10^{\circ}$ for 7 days; Following storage, physicochemical and sensory characteristic comparisons were performed. Temperature for all test materials ranged between 15.2-20. $9^{\circ}C$, water activity was maintained near 0.96, and the pH levels of the samples were 6.44, 6.29, and 6.35, respectively. Residual chlorine levels were generally low, ranging between 0.01 and 0.02. The physicochemical qualities of the samples were evaluated according to the storage method and temperature. Brightness(L value), redness(a value), and yellowness(b value) tended to increase with increasing storage time. The evaluated sensory characteristics included appearance, color, smell, taste, texture, and overall acceptance. With regard to storage temperature the vinegar-treated samples were evaluated as superior, receiving a score of 7.00, and the ingredients stored at $3^{\circ}C$ were evaluated as significantly (p< 0.001) superior to those stored at $10^{\circ}C$. Overall, vinegar is an effective disinfectant to apply in the preparation of raw vegetables that are typically served without heating, and which can cause serious food safety issues when contaminated.

  • Objectives : The purpose of this study is to review the effectiveness of fire needling treatment for knee osteoarthritis in comparison with manual acupuncture treatment. Methods : Through four foreign online databases (PubMed, Cochrane library, EMBASE, and CNKI) and five domestic online databases (NDSL, RISS, KISS, OASIS, and KTKP), we searched for clinical studies that performed fire needling treatment for knee osteoarthritis until May 10, 2019. Only randomized controlled trials were selected and we assessed the risk of bias according to the Cochrane RoB criteria. This review examined the selected studies into first author, publication year, sample size, outcome measurements, results, acupoints, treatment time & period and so on. Results : A total of 7 RCTs were selected in this review and all were conducted in China. Treatment period of more than 4 weeks and treatment visits of 10 to 20 times were the most common. EX-LE4 and ST35 (=EX-LE5) acupoints were most frequently selected in treatment. Among the evaluation indexes, a total efficacy rate was used the most. Most of fire needling groups showed more significant results compared with the manual acupuncture groups statistically. Conclusions : All studies showed that fire needling treatments for knee osteoarthritis were more effective than manual acupuncture treatments statistically. Therefore, the results of this study could be utilized as a preliminary data for another clinical research on fire needling treatment for knee osteoarthritis. However, further well-designed randomized controlled trials will be needed to develop sufficient evidence about the effectiveness and safety of fire needling treatment for knee osteoarthritis in the future.

  • This study is about the research of living environment in residential areas created by the land readjustment projects in the modern era, and recently lifted from Residential Environment Improvement district at the same time. The five criteria for evaluating the residential area are safety, health, convenience, comfort, and sustainability. The level of resident satisfaction in general is as follows. [completely dissatisfy as 5.30%, dissatisfy as 16.29%, neutral as 49.62%, satisfy as 16.29% and completely satisfy as 6.82%]. The results of the five survey items on the residential areas show that residents are aware of the area not as an old residential area to be demolished, but as a comparatively excellent residential area, namely very different results from the designation criteria of the redevelopment area designated by the Urban and Residential Environment Improvement Act. If the road conditions and the deterioration of the buildings are judged to be designated as the redevelopment area and to be removed these settlements, the residential areas with social sustainability could demolished. Based on this study, it is necessary to conduct the research to find out the reason for deriving the results of each evaluation item in the succeeding study. These studies are needed to rediscover, to develop and manage the value of many old residential areas scattered in the city centers of local areas.

  • Objectives The purpose of this study was to analyze the trend of recent randomized controlled trials (RCTs) that used herbal medicine for the treatment of tic disorders in China and to evaluate the efficacy and safety of the treatment. Methods RCTs published from January 2017 to December 2021 were searched for using the China National Knowledge Infrastructure (CNKI). These were then analyzed using herbal medicine treatment methods and their results. Results A total of 35 randomized controlled trials were selected and analyzed. In most studies, evaluation indicators such as the Yale tic symptom scale and total effective rate were significantly improved in the herbal medicine treatment group compared to the control group. The most commonly used herb for tic disorder was Uncaria Rhynchophylla (釣鉤藤), followed by Glycyrrhizae Radix (甘草), Gastrodiae Rhizoma (天麻), Paeoniae Radix Alba (白芍藥), Batryticatus (白殭蠶), Poria (茯笭), and Bupleuri Radix (柴胡). In all studies that reported adverse events, herbal medicine was identified as a relatively safe treatment with fewer adverse reactions or no significant difference compared with the control group. Conclusions Based on the results of RCTs, herbal medicine has been shown to be safe and effective for the treatment of intellectual disability. However, additional well-designed large-scale clinical trials are needed to confirm these findings.

  • Cardiotoxicity assessment of all drugs has been performed according to the ICH guidelines since 2005. Non-clinical evaluation S7B has focused on the hERG assay, which has a low specificity problem. The comprehensive in vitro proarrhythmia assay (CiPA) project was initiated to correct this problem, which presented a model for classifying the Torsade de pointes (TdP)-induced risk of drugs as biomarkers calculated through an in silico ventricular model. In this study, we propose a TdP-induced risk group classifier of artificial neural network (ANN)-based. The model was trained with 12 drugs and tested with 16 drugs. The ANN model was performed according to nine features, seven features, five features as an individual ANN model input, and the model with the highest performance was selected and compared with the classification performance of the qNet input logistic regression model. When the five features model was used, the results were AUC 0.93 in the high-risk group, AUC 0.73 in the intermediate-risk group, and 0.92 in the low-risk group. The model's performance using qNet was lower than the ANN model in the high-risk group by 17.6% and in the low-risk group by 29.5%. This study was able to express performance in the three risk groups, and it is a model that solved the problem of low specificity, which is the problem of hERG assay.

  • Purpose: The small-scale environmental impact assessment conducted during the development project stage has focused on the preservation of the natural environment centered on non-urban areas, due to the nature of urbanization, health problems for citizens of high-density urban areas have a limitation in that they are relatively neglected. In the case of strategic environmental impact assessment and environmental impact assessment in urban areas, there is no basis for evaluation in urban areas because there are exceptions to be excluded from the target projects or there are no target project regulations for buildings. Therefore, in this research, we examined the problems with the target project such as the current environmental impact assessment, and tried to establish a system improvement plan that can solve them. Research design, data and methodology: After reviewing the current environmental impact assessment-related laws (including enforcement ordinances) and national land planning laws (including enforcement ordinances), exceptions such as environmental impact assessment in urban areas were identified and problems were identified. Based on this, an amendment to the Enforcement Decree was proposed to provide institutional support for the expansion of target projects such as environmental impact assessment in urban areas. Results and Conclusions: Through this research, it is expected that the projects subject to environmental impact assessment on development projects in urban areas directly related to the health of the people will be expanded, and the net function of the environmental impact assessment system will be maximized.

  • A lithium-ion battery exhibits high energy density but has many limitations due to safety issues. Currently, as a solution for this, research on solid state batteries is attracting attention and is actively being conducted. Among the solid electrolytes, sulfide-based solid electrolytes are receiving much attention with high ion conductivity, but there is a limit to commercialization due to the relatively high price of lithium sulfide, which is a precursor material. This study focused on the possibility of relatively inexpensive and light lithium hydride and conducted an experiment on it. In order to analyze the characteristics of LiAlH4, ion conductivity and thermal stability were measured, and a composites mixed with PVDF, a representative polymer electrolyte, was synthesized to confirm a change in characteristics. And metallurgical changes in the material were performed through XRD, SEM, and BET analysis, and ion conductivity and thermal stability were measured by EIS and LFA methods. As a result, Li3AlH6 having ion conductivity higher than LiAlH4 is formed by the synthesis of composite materials, and thus ion conductivity is slightly improved, but thermal stability is rapidly degraded due to structural irregularity.

  • This study aimed to evaluate the clinical efficacy and safety of acupuncture and electroacupuncture for temporomandibular joint disorder (TMD). We searched 11 databases to find randomized-controlled trials (RCTs) published between January 2018 and January 2023 that used acupuncture and electroacupuncture to treat patients with TMD. We performed a meta-analysis of 18 RCTs involving 1,109 patients. Nine studies reported that the treatment and control groups showed improvement in the evaluation index post-treatment. The results of the meta-analysis showed that the treatment groups receiving acupuncture combined with manual therapy had significantly improved visual analog scale score and dysfunction index than the control groups receiving manual therapy. Moreover, the treatment groups receiving acupuncture combined with Western medicine had statistically improved maximum mouth opening than the control groups using Western medicine. In conclusion, acupuncture and electroacupuncture have clinical effects on TMD patients. Given that 11 studies were obtained from the Chinese database, a regional bias would be considered. Furthermore, the included studies had high a risk of bias in terms of randomization, concealment, and blinding. Further studies are required to correct these limitations.
