This article is to investigate into the philosophical background and the applicability of the humanities programmes effectively to practice them, not to educate the religious doctrines, based on the traditional-cultural resources in the education center affiliated with the religious institution. These humanities programmes can be understood on the lifelong education associated with a person. In the light of common curriculum practising in the existing education center, contents of those programmes are reviewed with classifying the humanities programmes into 3 parts, that is, eastern classical language education, eastern classical education, and eastern traditional prognosticating arts branching off from the eastern philosophy. Eastern classical language education indicates the classical Chinese characters and literatures in the context of our historical tradition. Eastern classical education implies the education which can acquire classical literatures in a modern way, as a accumulation of knowledges having been in charge of a person's lifelong education, and as a entity responsible for making a person to bring to maturity of his character by comprehending the life of human being and the world in pre-modern, Finally, the eastern philosophy is chosen for the reason that have the very interesting contents which can report facts that recover the integral relationship between nature and human being lacking in contemporaries, and instead of rejecting to interpret human being excessively in terms of materialism, is a significant one endowed with the mission which should develop his potentials through the his lifelong. Especially, eastern traditional prognosticating arts are selected that people has considered with them so kindly, and are the knowledges forming the cores of national culture. It may be a very important that attempts to develop the humanities programmes practising in the education center affiliated with the religious institution are not only the demands of the times in our days, but also a new teaching way replacing with old fashioned teachings.

The purpose of this study was to define the 'caligraphy as a modern concept of art. For this purpose, it was necessary to exclude the elements betraying 'the caligraphy as a pure art' in reference to 'autonomy' as an indicator of modernity in order to reflect on the current topology of the caligraphy in our age. Checking the current conditions facing the caligraphy from the pre-modern, modern and post-modern perspectives will clarify the current topology of the caligraphy and further exploring 'the caligraphy as a post-modern art concept. To this end, this study defines the caligraphy 'as a pure formative art' and thereby discusses it in terms of nature and form. In terms of nature, the caligraphy should be subsumed into a spacial art, but it has a nature of a temporal art created and appreciated over time. Hence, among the spacial arts, the painting is most similar to the caligraphy, while among the temporal arts, the caligraphy is most similar to such rhythmic (of high mobility) or performing arts as music and dance. Merely, the painting does not reveal the flow of time on the canvas, while music and dance leave no residual in terms of audibility and visuality. All in all, the caligraphy is sort of 'temporal-spacial art' like dance in that the visible letters express the artist's sense of life on the plane over time like music. In terms of form, this study compares the caligraphy with engraving, wood print and character design to define the caligraphy as a pure art concept. The caligraphy as a modern art concept, namely, the autonomy of the caligraphy is associated with legibility and meaning in addition to the question whether it is an applied or a pure art. The legibility and meaning of the characters are not only the essential elements of the caligraphy but also are the factors limiting its autonomy, which must be a paradox. All in all, the legibility and meaning of the characters must be the key criteria for determining the caligraphy as a practical art or literary art or as a pure figurative art. In this context, this study discusses the caligraphy as a pure art by comparing it with the spatial art 'painting' and the temporal art 'music.' It might be impossible to define the caligraphy or a genre of art as an autonomous art of self-perfection and categorical identity. Moreover, any attempt to define the caligraphy would fail to interpret the caligraphy appropriately. Merely, we are obliged to position the caligraphy in the process of localizing 'their modernity' and thereby, discuss how to respond to their scheme.

This study aimed to verify how a multisensory storytelling-based activity-based intervention affects social interaction in children with cerebral palsy. As a quasi-experimental investigation, this study used a single-blind, two-group pre-post test design. This study comprised 24 children aged 7 to 8 y who had been diagnosed with spastic cerebral palsy and were classified as having GMFCS stages I to III. Twelve children were randomly assigned to experimental and control groups, with neither the children nor their guardians knowing which group they were placed in. The group program comprised 16 sessions of 60 min each, twice a week for eight weeks. The experimental group engaged in an activity-centered intervention centered on multisensory storytelling, whereas the control group engaged in structured physical activity. The activities were assessed using the peer relations skills scale to determine the extent to which social interaction had changed prior to and during the child's intervention. The SPSS 25.0 for Windows (IBM Corp, USA) application was used to analyze the data, and the significance level (α) for statistical verification was set to 0.05. Furthermore, the Wilcoxon Signed-Rank and Mann-Whitney U tests were used to assess the differences in social interaction between the experimental and control groups. Significant differences were observed in the total of the peer relationship skill scale and cooperation and empathy areas of the subtest in the intragroup change of the peer relationship skill scale between the experimental and control groups. However, the experimental group demonstrated a significant difference in the initiative area, whereas the control group demonstrated no significant difference. A significant difference was observed in the amount of change between the two groups in the initiative area and total of the subtest of peer relationship skills but no significant difference in the collaboration and empathy areas. We gave a multisensory storytelling-based activity-based intervention based on multisensory storytelling to children with cerebral palsy and saw a significant improvement in peer relationship skills. It may be proposed as an effective intervention strategy for children with cerebral palsy who struggle with social contact.

Purpose: This paper reports the short-term clinical and radiological results of unilateral biportal endoscopic decompression (UBE) to prove its efficacy. Materials and Methods: Twenty patients who received unilateral biportal endoscopic far-lateral decompression (UBEFLD) were analyzed statistically using the visual analogue scale (VAS), modified Macnab criteria and Oswestry Disability Index (ODI) clinically. Radiologically, their intervertebral angle (IVA), percentage slip, disc height index (DHI) and foraminal height index (FHI) were analyzed pre- and postoperatively. Results: The VAS scores were 6.20 preoperatively, which improved to 2.05, 1.75 and 1.45 at postoperative one month, three months and one year, respectively (p<0.001). The modified macnab criteria in both the good or excellent category was 70.0%, 80.0% and 85.0% at postoperative one month, three months and one year, respectively (p=0.034). The ODI improved from 59.8% preoperatively to 35.8%, 33.2%, and 17.1% at postoperative one month, three months, and one year, respectively (p<0.001). The IVA was increased 0.40±0.88 after a surgery (p=0.057). Percentage slip was increased 0.19% after surgery (p=0.134). The DHI changed from 0.49 preoperatively to 0.62 postoperatively (p=0.359), and the FHI changed from 0.71 preoperatively to 0.79 postoperatively (p<0.001). Conclusion: UBEFLD displayed satisfactory results. Such a result highlights the potential of UBEFLD as an excellent alternative to spinal fusion or microscopic surgery.

This study was conducted to compare the egg productivity, egg quality, and blood characteristics of laying hens with different laying rates, and the frequency and cumulative duration of the sitting behavior observed before laying was investigated. Twelve 45-week-old Hy-Line Brown laying hens were randomly assigned to two treatment groups with three replicates. Treatment groups were classified as layers laying over 80%(high egg performance layers; HEP) and layers laying below 50%(poor egg performance layers; PEP). The experiment lasted 4 weeks. HEP showed higher hen-house egg production ratio and egg mass and lower feed conversion ratio(FCR) (P<0.05) compared with PEP, although egg weight was higher in PEP (P<0.05). In terms of egg quality, PEP showed differences in eggshell quality (eggshell color, eggshell thickness, and eggshell weight) (P<0.05). Additionally, HEP showed high triglycerides(TG), and PEP showed high alanine transaminase(ALT) level (P<0.05) in serum collected in the morning. In the afternoon, the HEP showed higher lactate dehydrogenase(LDH) levels (P<0.05). No differences in the Ca: P ratio were observed between layers with different laying rates. One hour before egg laying, HEP exhibited sitting behavior 4 times on average, each lasting 25 minutes. In conclusion, egg production and quality differ between HEP and PEP, and HEP showed frequent sitting behavior before egg laying. However, additional research is necessary to explore approaches other than specific behavioral observation to distinguish poor layers in the flock for application in farms.

Tenebrio molitor larvae is well known as edible insect. Then, although it has been widely studied that Tenebrio molitor larvae has various bioactive functions such as antioxidant, anti-wrinkle, and anticancer. Nevertheless, antioxidant effects of Tenebrio molitor larvae water extract (TMH) has not been well described in Adult Retina Pigment Epithelial cell line (ARPE-19). In this study, we demonstrated that antioxidant effects of TMH against H₂O₂-induced oxidative stress in ARPE-19. Thus, we selected for our studies and performed a series of dose-response assay to determine the working concentration that lead to a consistent and high degree of cytotoxicity, which we defined as the level of H₂O₂ that killed 40% of the ARPE-19 cells. ARPE-19 cells were pre-treated with various concentrations of TMH (0.1 up to 2 mg/ml) before exposure to 300 µM H₂O₂. As we expected, TMH effectively prevented ARPE-19 cells from 300 µM H₂O₂-induced cell death in a dose-dependent manner. Furthermore, TMH inhibited the phosphorylation of mitogen-activated protein kinases (MAPKs) such as extracellular signal regulated kinase (ERK), c-Jun N-terminal kinase (JNK), and p38. Overall, the inhibitory effects of TMH on H₂O₂-induced apoptosis and oxidative stress were associated with the protection cleaved caspase-3, Bax, Bcl-2, and HO-1. The TMH suppressed H₂O₂-induced cell membrane leakage and oxidative stress in ARPE-19 cells. Thus, these results suggest that the TMH plays an important role in antioxidant effect in ARPE-19.

There is a lack of knowledge and information on the understanding and application of the Process Safety Management (PSM) system, recognized as a major cause of industrial accidents in small-and medium-sized workplaces. Hence, it is necessary to prepare a protocol to secure the practical and continuous levels of implementation for PSM and eliminate human errors through tracking management. However, insufficient research has been conducted on this. Therefore, this study investigated and analyzed the various violations in the administrative measures, based on the regulations announced by the Ministry of Employment and Labor, in approximately 200 small-and medium-sized PSM workplaces with fewer than 300 employees across in korea. This study intended to contribute to the prevention of major industrial accidents by developing a facility maintenance web program that removed human errors in small-and medium-sized workplaces. The major results are summarized as follows. First, It accessed the web via a QR code on a smart device to check the equipment's specification search function, cause of failure, and photos for the convenience of accessing the program, which made it possible to make requests for the it inspection and maintenance in real time. Second, it linked the identification of the targets to be changed, risk assessment, worker training, and pre-operation inspection with the program, which allowed the administrator to track all the procedures from start to finish. Third, it made it possible to predict the life of the equipment and verify its reliability based on the data accumulated through the registration of the pictures for improvements, repairs, time required, cost, etc. after the work was completed. It is suggested that these research results will be helpful in the practical and systematic operation of small-and medium-sized PSM workplaces. In addition, it can be utilized in a useful manner for the development and dissemination of a facility maintenance web program when establishing future smart factories in small-and medium-sized PSM workplaces under the direction of the government.

Sedimentation and pH neutralization has been investigated as preteatment of acid contaminate water. The settling and neutralizing process derive more effective degradation efficiency as the pre-treatment process before the removal process of adsorption, volatile, biodegradation, or oxidation. Settling velocity, uniformity coefficient, coefficient of curvature, and grain size index can define in the sedimentation process for characteristics of the soil. The stainless steel sieve has been used to separate each particle size of the dry soil by assembling in order of 4, 10, 20, 40, 80, 100, and 200 mesh sizes. The soil from Gamcheon Port in Busan drops upper side of the sieve and shakes back and forth to separate each different size of the particle. The 1L of Imhoff cone and 200 mL of the mass cylinder were used as settling tanks to calculate settling velocity. Stokes' equation was used to figure out the average density of dry soil with a value from settling velocity. In the results, the average particle density and lowest settling velocity were 1.93 g/cm³ and 0.11 cm/s, respectively. These values can detect the range of settling points of sediment to prevent chemical accidents. In pH neutralization, the initial pH of 2, 3, 4, and 5 of nitric acid and sulfuric acid are used as an acid solution; 0.1, 0.01, and 0.001 M of sodium hydroxide and calcium hydroxide are used as a base solution. The main goal of this experiment is to figure out the volume percentage of the acid solution becomes pH 7. The concentration of 0.001 M of base solution exceeds all the conditions, 0.01 M exceeds partially, and 0.1 M does not exceed 5 v/v% except pH 2. Calcium hydroxide present less volume than sodium hydroxide at pH neutralization both sulfuric and nitric acid.

Purpose: The purpose of this study was to introduce the ultrasound-guided transmeniscal injection in medial compartment knee osteoarthritis and analyze the clinical outcomes. Materials and Methods: The electronic medical records of 36 patients with medial compartment knee osteoarthritis who were treated with an ultrasound-guided transmeniscal injection from March 2019 to July 2019 were accessed for this retrospective review. Using an ultrasound guided spinal needle, the patients received an intra-articular steroid injection at the medial compartment of the knee. A physical examination was conducted at the initial visit (pre-injection), and at one week, four weeks, and eight weeks after the injection. The numeric pain rating scale (NRS), Lequesne index, and Western Ontario and McMaster Universities Osteoarthritis (WOMAC) score were measured at each visit and analyzed over time. The percentage change of the patients who revealed substantial improvement was analyzed. The NRS, Lequesne index, and percentage of patients, who revealed substantial improvement over time classified by osteoarthritis grade, were analyzed. Results: The NRS and Lequesne index decreased at one week, four weeks, and eight weeks after the injection compared to the initial baseline, and the pain-relief effect continued without change until eight weeks. The percentage of patients who showed substantial improvement at one, four, and eight weeks was 50.0%, 47.2%, and 52.8%, respectively. The WOMAC scores decreased at one, four, and eight weeks compared to the initial baseline, and the decrease was continued without any difference until eight weeks. The percentage of patients with osteoarthritis stage 1 or 2 who revealed more than substantial improvement was significantly higher at one, four, and eight weeks than those with osteoarthritis stages 3 or 4 (p<0.05). Conclusion: In patients with medial compartment knee osteoarthritis, the pain reduction and functional improvement persisted for at least eight weeks after the ultrasound-guided transmeniscal injection at the medial compartment. In particular, patients with medial compartment osteoarthritis stage 1 or 2 showed more effective pain reduction.

Two dominant thrips in hot pepper (Capsicum annuum) cultivating in greenhouses are Frankliniella occidentalis and F. intonsa in Korea. This study investigated their overwintering physiology. These two thrips were freeze-susceptible and suppressed the body freezing temperature by lowering supercooling point (SCP) down to -15~-27℃. However, these SCPs varied among species and developmental stages. SCPs of F. occidentalis were -25.7±0.5℃ for adults, -17.2±0.3℃ for pupae, and -15.0±0.4℃ for larvae. SCPs of F. intonsa were -24.0±1.0℃ for adults, -27.0±0.5℃ for pupae, -17.2±0.8℃ for larvae. Cold injuries of both species occurred at low temperature treatments above SCPs. Thrips mortality increased as the treatment temperature decreased and its exposure period increased. F. occidentalis exhibited higher cold tolerance than F. intonsa. In both species, adults were more cold-tolerant than larvae. Two thrips species exhibited a rapid cold hardening because a pre-exposure to 0℃ for 2 h significantly enhanced the cold tolerance to a lethal cold temperature treatment at -10℃ for 2 h. In addition, a sequential exposure of the thrips to decreasing temperatures made them to be acclimated to low temperatures. To investigate the overwintering sites of the two species, winter monitoring of the thrips was performed at the greenhouses. During winter season (November~February), adults of the two species were not captured in outside of the greenhouses. However, F. occidentalis adults were captured to the traps and observed in weeds within the greenhouses. F. occidentalis adults were also emerged from soil samples obtained from the greenhouses during the winter season. F. intonsa adults did not come out from the soil samples at November and December, but emerged from the soil samples obtained after January. To determine the adult emergence due to diapause development, two thrips species were reared under different photoperiods. Adult development occurred in all photoperiod treatments in F. occidentalis, but did not in F. intonsa especially under short periods. Tomato spotted wilt virus, which is transmitted by these two species, was detected in the weeds infested by the thrips during the winter season. These results suggest that F. occidentalis develops on weeds in the greenhouses while F. intonsa undergoes a diapause in the soil during winter.
