Peripheral neuropathy is a disease of multiple Peripheral nerves. Tingling, pins-and needles, numbness, burning and raw sensation are symptoms of peripheral neuropathy. These symptoms are frequently complained by patients who suffered from obstructive syndrome of Ki and blood (痺證). This case was reported to evaluate the effects of oriental medicine therapy on a patient with obstructive syndrome of Ki and blood (痺證). The subject was a female patient who had obstructive syndrome of Ki and blood (痺證). She complained of calf pain, cold sense, walking discomfort, insomnia, dyspepsia, anorexia etc. We administered the medicine with dispeling the cold pathogenic factor (寒邪), adjusting the constructive and defensive energy (調營衛), tonifying the Ki and blood (補氣血) by stage. After the treatment, the symptoms improved. This case suggests that oriental medicine therapy can be applicable to improve in symptoms with Peripheral neuropathy.

Fuzzy control is proposed to regulate cutting force in turning operations under varying cutting conditions. The traditional linear controllers based on crisp mathematical model cannot effectively control cutting force becasue of the nonlinear dynamics of turning operations. The proposed fuzzy controller is based on operator experience and expert knowledge. The membership functions for the inputs and the output of the controller are designed. Cutting force is regulated by adjusting feedrate according to the variation of cutting conditions. The performance of the proposed controller is evaluated by experiments. The results of experiments show that the proposed fuzzy controller has a good cutting force regulation over a wide range of cutting conditions.

The animal naming test (ANT) is known to be influenced not only by age, gender, and education but only by ethnicity, culture, and language. Thus, population-specific norm considering these variables needs to be developed for Korean-speaking elderly. We evaluated 185 healthy elderly people with five measures. Education was the single statistically independent correlate of the total number of words ($R^2$ = .312, p = .038). After adjusting for education, there was slightly significant negative correlation (r = -.215, p = .049) between age and total number of words. Mean number of words produced was $13.71{\pm}3.09$. The production frequency was negatively correlated with the typicality rating (r = -0.41, p < .05). The concrete and exact scoring rule could be set up in the comparison of naming performance between a normal and patient with neuro-linguistic disorder and its data could be utilized in a differential diagnosis for patients with neurological disorders.

In this paper, I propose a method for detection of look-alike offenders by using hidden face information. For extraction of moving objects, PRA matching is used to extract moving components, and brightness changes can be dealt with by an adaptive threshold adjusting in the proposed method. Moving objects extracted in the territory of the face region is extracted using the complexion, facial area, eyes, nose, mouth. The extracted information detected by the presence of these characteristics were likely to help judge a person. Results of the extracted face makes the recognition rate of possible murderers 90% so the usefulness of the proposed method was confirmed.

Purpose: This study explored the adjustment experiences of spouses of elderly people with dementia in Korea. Methods: A grounded theory method was used. The data were collected by individual in-depth interviews with 11 spouses of elderly people with dementia. Results: In the analysis, 17 categories were derived. A core category emerged: Adjusting to daily life of providing love-based care. Eight major strategies for dealing with the psychosocial problems faced by spouses of elderly people with dementia: Feeling one's own responsibility in caring; halting personal activities; adopting a spouse-oriented daily lifestyle; caring with love; efforts for maintaining one's own health; efforts for maintaining spouse's health; depending on religious belief; and trying to have time for oneself. The consequences that resulted from applying these strategies were identified as "feeling worthwhile for caring," "maintaining a peaceful life," and "being grateful of the present." Conclusions: This study presents a holistic view of the adjustment experiences of spouses of elderly people with dementia. This study can also provide directions for developing interventions for enhancing the quality of life of spouses of elderly people with dementia.

Epithelial to mesenchymal transition (EMT) is an important etiologic factor for the development of peritoneal fibrosis in CAPD patients. Mesothelial cells are main source of trans-differentiated fibroblasts under stress from the bioincompatible peritoneal dialysate. In our study there was no difference in dialysate TGF-${\beta}$ and VEGF between the low and high GDP groups during an initial 12 months. However, after adjusting with D-CA125, the low GDPs group showed a significantly lower D-TGF-${\beta}$/D-CA125 and D-VEGF/CA125 during the initial 12 months. Among the adjusted peritoneal growth factors for CA125, VEGF/CA125 and TGF-b/CA125 were factors significantly associated with greater EMT in this study. Adjustment of the peritoneal growth factor for effluent CA125 (surrogate for mass of HPMCs) revealed significant association with EMT suggesting that the fibroblastoid transition from HPMCs could be affected by the amount of intraperitoneal growth factors (TGF-b, VEGF) per unit mass of HPMCs. There was significant improvement in both cell score and D-CA125 at the sixth and 12th months after switching from a high GDPs solution to a low GDPs solution. Use of icodextrin solution in patients who had average peritoneal transport showed not only better systemic effects such as decreased glucose absorption via dialysate but also preservation of the peritoneum, including less EMT and high mesothelial bulk mass. In conclusion, Therapy with low GDP solution including icodextrin may positively impact preservation of the peritoneal membrane integrity and prevention of peritoneal fibrosis with time on PD.

Inflammation can be a causative factor for carcinogenesis or can result from a consequence of cancer progression. Moreover, cancer therapeutic interventions can also induce an inflammatory response. Various inflammatory parameters are used to assess the inflammatory status during cancer treatment. It is important to select the most optimal biomarker among these parameters. Additionally, suitable biomarkers must be examined if there are no known parameters. We briefly reviewed the published literature for the use of inflammatory parameters in the treatment of patients with cancer. Most studies on inflammation evaluated the correlation between host characteristics, effect of interventions, and clinical outcomes. Additionally, the levels of C-reactive protein, albumin, lymphocytes, and platelets were the most commonly used laboratory parameters, either independently or in combination with other laboratory parameters and clinical characteristics. Furthermore, the immune parameters are classically examined using flow cytometry, immunohistochemical staining, and enzyme-linked immunosorbent assay techniques. However, gene expression profiling can aid in assessing the overall peri-interventional immune status. The checklists of guidelines, such as STAndards for Reporting of Diagnostic accuracy and REporting recommendations for tumor MARKer prognostic studies should be considered when designing studies to investigate the inflammatory parameters. Finally, the data should be interpreted after adjusting for clinically important variables, such as age and cancer stage.

The concept of virtual synchronous generators (VSGs) is a valuable means for improving the frequency stability of microgrids (MGs). However, a great virtual inertia in a VSG's controller may cause power oscillation, thereby deteriorating system stability. In this study, a small-signal model of an MG with two paralleled VSGs is established, and a control strategy for maintaining a constant inertial time with an increasing active-frequency droop coefficient (m) is proposed on the basis of a root locus analysis. The power oscillation is suppressed by adjusting virtual synchronous reactance, damping coefficient, and load frequency coefficient under the same inertial time constant. In addition, the dynamic load distribution is sensitive to the controller parameters, especially under the parallel operation of VSGs with different capacities. Therefore, an active power increment method is introduced to improve the precision of active power sharing in dynamic response. Simulation and experimental is used to verify the theoretical analysis findings.

Objectives: This study aimed to evaluate the relationship between pit and fissure sealants of the molars, and caries prevalence and experience to assess the effect of sealants on caries prevention. Methods: Data from 16,119 people were extracted from the seventh Korean national health and nutrition examination survey, which was conducted from 2016 to 2018. Demographic, socioeconomic, oral health-related behavioral, and oral examination survey data were collected as independent variables. SAS statistics for complex samples and multiple logistic regression analysis (Windows ver. 9.4) was used for the statistical analyses. Results: Caries prevalence and experience were significantly associated with age, sex, daily toothbrushing frequency, interdental cleaning, and having molar sealant. Multiple logistic regression analysis revealed a significant association between having molar sealants and the caries prevalence and experience among participants under 30 years of age after adjusting socio-economic variables and toothbrushing-related factors. Conclusions: This study confirmed the effect of molar sealants on caries prevention in Korea. Our results support that the application of molar sealants in children, adolescents, and young individuals is effective in preventing caries.

Objectives In regard to the social competition hypothesis, depression is viewed as an involuntary defeat strategy. A previous study has demonstrated that adaptation in microenvironments can result in a wide range of behavioural patterns including defense activation disorders. Using a simulation model with evolutionary ecological agents, we explore how the fitness of various defence activation traits has changed over time in different environments with high and low social mobility. Methods The Evolutionary Ecological Model of Defence Activation Disorder, which is based on the Marginal Value Theorem, was used to examine changes in relative fitness for individuals with defensive activation disorders after adjusting for social mobility. Results Our study examined the effects of social mobility on fitness by varying the d-values, a measure of depression in the model. With a decline in social mobility, the level of fitness of individuals with high levels of defense activation decreased. We gained insight into the evolutionary influence of varying levels of social mobility on individuals' degrees of depression. In the context of a highly stratified society, the results support a mismatch hypothesis which states that high levels of defence are detrimental. Conclusions Despite the fact that niche specialization in habitats composed of multiple microenvironments can result in diverse levels of defensive activation being evolutionary strategies for stability, decreased social mobility may lead to a decrease in fitness of individuals with highly activated defence modules. There may be a reason behind the epidemic of depression in modern society.
