The use of fermented soy curd as a functional substance has been actively studied due to the anti-inflammatory and antiallergic activity of soybean protein hydrolyzate by enzymes of lactic acid bacteria. The present study investigated the potential of soy curd as a treatment for atopic dermatitis (AD). Pediococcus inopinatus Y2 (P. inopinatus Y2) lactic acid bacteria were inoculated into soy milk and fermented ($30^{\circ}C$, 24 hr). Changes in body weights, ear thicknesses, IgE concentrations, and weights of immune organs in ICR female mice were quantified. Moderate weight gain occurred in most of the groups. The ear thickness was lowest in the untreated group (no group), and it was allergic and thickened in the phthalic anhydride (PA) treatment group. Based on visual observations, as compared with the skin condition of the PA-induced AD group, the skin condition of the animals in the fermented soy curd (FSC) group was improved. Therefore, FSC by lactic acid bacteria seemed to improve AD. Based on the comparison of the weights of the spleen, thymus, and lymph nodes, as well as the results of the IgE analysis, soy milk, in addition to FSC, had a therapeutic effect. However, the antiallergy effects of FSC in terms of AD were far superior to those of soy milk. These results indicated that FSC can be used as a treatment for AD.

The purpose of this study was to explore the progression levels of science metamodeling knowledge through using questionnaires for 97 students of the gifted in G science academy. As a result of the Rasch model analysis, it was confirmed that the progression levels of the scientific metamodeling knowledge is suitable for the person reliability of 0.71 and the item reliability of 0.96. The progression levels of students' science metamodeling knowledge were classified into 4 stages. First and second levels were considered model to be objective and the third and fourth stages were perceived as subjective. The first level is to view the model as a visual representation of a phenomenon as it is, and the second level is to think that the model corresponds to objective knowledge or theory and is a tool for explanation. The Third level looks at the model as a scientist's exploration tool and fourth level is to think that the model is provisional one and multiple models can coexist in one phenomenon. The progression levels of science metamodeling knowledge of science high school students derived from this study is expected to be used as a reference when constructing a curriculum for science modeling and modeling for gifted students.

Objective : The aim of the study was to investigate the application of nonpharmacological cognitive interventions in patients with dementia. Methods : We searched published studies in KISS, PubMed, and Sciencedirect databases from January 2013 to December 2017. The main keywords used were "Dementia" AND "Cognitive stimulation OR Cognitive rehabilitation OR Cognitive training" and a total of ten studies were selected for analysis from 753 searched articles. Results : Seven of the ten selected studies showed significant improvements in cognitive function after intervention, whereas three studies showed no improvement in cognitive function; however, activation of brain waves, improvement in the relationship between care givers and patients, improvement in the quality of life of care givers, and improvements in visual motor skills were shown. Mini-Mental State Examination(MMSE) was used as the assessment tool for identifying the effects of the cognitive function improvement, and in four studies the quality of life of dementia patients was measured as an intervention effect. The main subject of the cognitive intervention is patients with mild to moderate dementia. Conclusion : The results of this study can be used as a basis for the selection of intervention methods, as well as their duration and assessment, according to the characteristics of dementia patients.

In this study, we present a decision function of optimal smoothing parameter for baseline correction using Asymmetrically reweighted penalized least squares (arPLS). Baseline correction is very important due to influence on performance of spectral analysis in application of spectroscopy. Baseline is often estimated by parameter selection using visual inspection on analyte spectrum. It is a highly subjective procedure and can be tedious work especially with a large number of data. For these reasons, an objective procedure is necessary to determine optimal parameter value for baseline correction. The proposed function is defined by modeling the median value of possible parameter range as the length and order of the background signal. The median value increases as the length of the signal increases and decreases as the degree of the signal increases. The simulated data produced a total of 112 signals combined for the 7 lengths of the signal, adding analytic signals and linear and quadratic, cubic and 4th order curve baseline respectively. According to the experimental results using simulated data with linear, quadratic, cubic and 4th order curved baseline, and real Raman spectra, we confirmed that the proposed function can be effectively applied to optimal parameter selection for baseline correction using arPLS.

Study Design: Level III retrospective cross-sectional study. Purpose: To define and characterize the presentation, symptom duration, and patient/surgical risk factors associated with 'post-decompressive neuropathy (PDN).' Overview of Literature: PDN is characterized by lower extremity radicular pain that is 'different' from pre-surgical radiculopathy or claudication pain. Although it is a common constellation of postoperative symptoms, PDN is incompletely characterized and poorly understood. We hypothesize that PDN is caused by an intraoperative neuropraxic event and may develop early (within 30 days following the procedure) or late (after 30 days following the procedure) within the postoperative period. Methods: Patients who consented to undergo lumbar laminectomy with or without an instrumented fusion for degenerative lumbar spine disease were followed up prospectively from July 2013 to December 2014. Relevant data were extracted from the charts of the eligible patients. Patient demographics and surgical factors were identified. Patients completed postoperative questionnaires 3 weeks, 3 months, 6 months, and 1 year postoperatively. Questions were designed to characterize the postoperative pain that differed from preoperative pain. A diagnosis of PDN was established if the patient exhibited the following characteristics: pain different from preoperative pain, leg pain worse than back pain, a non-dermatomal pain pattern, and nocturnal pain that often disrupted sleep. A Visual Analog Scale was used to monitor the pain, and patients documented the effectiveness of the prescribed pain management modalities. Patients for whom more than one follow-up survey was missed were excluded from analysis. Results: Of the 164 eligible patients, 118 (72.0%) completed at least one follow-up survey at each time interval. Of these eligible patients, 91 (77.1%) described symptoms consistent with PDN. Additionally, 75 patients (82.4%) described early-onset symptoms, whereas 16 reported symptoms consistent with late-onset PDN. Significantly more female patients reported PDN symptoms (87% vs. 69%, p=0.03). Patients with both early and late development of PDN described their leg pain as an intermittent, constant, burning, sharp/stabbing, or dull ache. Early PDN was categorized more commonly as a dull ache than late-onset PDN (60% vs. 31%, p=0.052); however, the difference did not reach statistical significance. Opioids were significantly more effective for patients with early-onset PDN than for those with late-onset PDN (85% vs. 44%, p=0.001). Gabapentin was most commonly prescribed to patients who cited no resolution of symptoms (70% vs. 31%, p=0.003). Time to symptom resolution ranged from within 1 month to 1 year. Patients' symptoms were considered unresolved if symptoms persisted for more than 1 year postoperatively. In total, 81% of the patients with early-onset PDN reported complete symptom resolution 1 year postoperatively compared with 63% of patients with late-onset PDN (p=0.11). Conclusions: PDN is a discrete postoperative pain phenomenon that occurred in 77% of the patients who underwent lumbar laminectomy with or without instrumented fusion. Attention must be paid to the constellation and natural history of symptoms unique to PDN to effectively manage a self-limiting postoperative issue.

Quantitative classification of insect fauna in transgenic rice in 2 LMO(Living genetically Modified Organism) isolated paddy fields (Gyeongsang National University, Gyeongbuk National University) and rice in 4 paddy fields(Duryang 1, Duryang 2, Hwagye 1, Hwagye 2), were evaluated for consecutive 5 years (2013 to 2017) in Sacheon, Gyeongnam province, and for 2 consecutive years (2015 to 2016) in Gunwi Gyeongbuk province. Sampling insect fauna were evaluated by black light trapping, sticky trapping, visual surveying, and sweeping methods in each target paddy field, respectively. A total of 37,941 individuals, of 464 species from 15 orders, were collected in Sacheon for 5 years. A total of 10,030 individuals, of 366 species from 13 orders, were collected in Gunwi for 2 years. Based on results of comparison between transgenic and non-transgenic paddy fields for 5 consecutive years, the similarity index between LMO paddy field and common paddy field is not different. Thus, this difference is not due to the environment, not the LMO.

This paper attempts to analyze the inner and outer structure of royal tombs that were built during the Joseon Period. This analysis is based on the relevant historical records and they were restored through visual composition in order to compare the features of Joseon royal tombs with those of Goryeo royal tombs and common tombs of the Joseon Period. Royal tombs of the Joseon Dynasty are structurally solid and contain a variety of artistic ornaments that symbolize guardian deities both inside and outside to protect the owners of the tombs for a long time. According to historical records such as Sejong sillok oryeui (Five Rites of State from the Annals of King Sejong) and Gukjo oryeui (Five Rites of State), it is presumed that the inner structure of royal tombs dating back to the early Joseon Period consisted of a stone chamber and that the byeongpungseok and nanganseok were built outside of the tomb. However, ever since King Sejo left it in his will not to make a stone chamber in his tomb, the royal tombs began to follow a new pattern, a burial pit outside the coffin filled with lime powder. Gukjo sangnye bopyeon (Supplement Book of the State Funeral Rites), which was compiled during the reign of King Yeongjo, is a book that shows how the royal tombs were formed in the late Joseon Period. The book explains in detail how lime powder was used to fill the burial pit of royal tombs. The byeongpungseok used during the late Joseon Period were engraved with peony flowers, while those previously made were engraved with twelve spirit warriors. Peony designs were frequently used to decorate the items of royal families, and the use of peony designs in tombs reflects the idea of regarding the royal tombs as an everyday living space for the deceased.

Background: Visual and somatosensory integration processing is needed to reduce pusher behavior (PB) and improve postural control in hemiplegic patients with acute stroke. Objects: This study aimed to investigate the effects of game-based postural vertical training (GPVT) on PB, postural control, and activity daily living (ADL) in acute stroke patients. Methods: Fourteen participants with acute stroke (<2 months post-stroke) who had PB according to the Burke lateropulsion scale (BLS) (score>2) were randomly divided into the GPVT group ($n_1=7$) and conventional postural vertical training (CPVT) group ($n_2=7$). The GPVT group performed game-based postural vertical training using a whole-body tilt apparatus. while the CPVT group performed conventional postural vertical training to reduce PB (30 minutes/session, 2 times/day, 5 days/week for 3 consecutive weeks). The BLS was evaluated to assess the severity of PB. And each subject's postural control ability and ADL level were assessed using the postural assessment scale for stroke (PASS), balance posture ratio (BPR), and Korean-modified Barthel index (K-MBI). Outcomes were measured pre- and post-intervention. Results: Comparison of the pre- and post-intervention assessment results showed that both interventions led to the following significant changes: decreased severity of PB scores and increased PASS, BPR, and K-MBI scores (p<.05). In particular, statistical analysis between the two groups, the BLS score was significantly decreased in the GPVT group (p<.05). And PASS, BPR, and K-MBI scores were significantly improved in the GPVT group than in the CPVT group (p<.01, respectively). Conclusion: This study demonstrated that GPVT lessened PB severity and improved postural control ability and ADL levels in acute stroke patients.
