COVID-19 pandemic has made the economy in Indonesia sluggish, especially Small and Medium Enterprises (SMEs). Simultaneously, the SMEs existence in Indonesia is fundamental and considered important by the government since it is able to assist numerous laborers and become an income source for the lower and middle classes of the community. The productivity of SME in a region will undeniably influence the availability of job and, of course, reduce the number of unemployed. Therefore, in this study, the researchers looked at how to improve SMEs performance to continue to exist amid the COVID-19 pandemic, by identifying the relationships between product characteristics, market competitive strategies, and the performance of SMEs. The research was done on SMEs in West Java, Indonesia. The example employed was Batik SMEs in Cirebon with at least 10 years in existence, and the total number of these SMEs was 165. As the basis of a quantitative approach, this study employed survey instruments by distributing a questionnaire. In analyzing the data, it utilized the structural equation modeling (SEM). The result showed a significant relationship between Product Characteristics, Market Competitive Strategy, and Price and Product Success Rate on SMEs Performance. This study's findings contribute to the SMEs performance literature.

For constructing the steel structures of ship and automobiles etc, thin plate welding has been extensively used in recent years. However. the welding of plate produces welding deformation and residual stress which sometimes extremely harm to the safty of structure in the course of construction and operation. Therefore, in order to accurately prediet the welding deformation and residual stress, it is important to exactly analyze the distribution of temperature during welding in thin plate and take into account the moving effect of the heat source. In this paper, two dimensional unstationary heat conduction problemes of thin plate are formulated using an isoparametric finite element. After the development of the computer program, this method is applied to some specimens, and the analyzed results are compared with the experimental ones to confirm the usefulness of this method.

Background: Recently the use of sedation by pediatric dentists in Korea is increased. This study describes training programs about sedation practices in Korean pediatric dentistry residency program. Methods: A questionnaire was filled in by participants of Korean Academy of Pediatric Dentistry on 17th-18th August, 2008. Also the data about sedation practices of the training institution is collected by phone call. Results: Seventy two percent of respondents used sedation. Most of them used sedation with agents under 25% of their patients. Distribution of ages in patients sedated with agents was 3 years, 4-5 years, under 2 years, 6-10 years, and more than 10 years. Determinative factors of using sedation were behavior management, number of visiting, amount of treatment and general condition, and oral route was the most favorable route. Sixty six percent of them have failed on sedation, and thity percent of them have rarely failed on sedation. Only fifty percent of dentists using sedation completed the cardiopulmonary resuscitation course. Conclusions: For safety, dentists using sedation need to be educated about emergency equipment and management. Especially medication dose, use frequency and the detail related to treatment procedure should be discussed carefully. Also putting a patient under general anesthesia and taking emergency measures should be discussed with Korean Dental Society of Anesthesiology.

The cross-linked polyethylene(herein after XLPE) insulated power cable emit the methane($CH_4$)gas in the course of chemical cross-linking process. The general stranded conductor easily discharge this methane gas through the gap of each stranded wires. But the special stranded conductor that filled with semi-conducting rubber compound to prevent water penetration which is applied to water proof type of cable(22.9kV CN/CV-W), disturb the methane gas emission. The pre-mold type cable joint shall be expanded gradually by emit of gas left in XLPE insulation. For example, sometimes the corona problem outbreak on a new power distribution line, resulted from the gap between the sleeve and semi-conductive layer of cable joint. If above mentioned problem especially happened on the way of operating. We have to shut down the line and try to discharge the methane gas in cable joint. In this point, we would like to explain the mechanism of methane gas & cable joint and our test result briefly. At last, we are pleased to introduce the solution for preventing reoccurrence of this problem.

Transforming growth factor-$\beta$ (TGF-$\beta$) is the prototypical multifunctional cytokine, participating in the regulation of vital cellular activities such as proliferation and differentiations as well as a number of basic physiological functions. The effects of TGF-$\beta$ are critically dependent on the expression and distribution of a family of TGF-$\beta$ receptors, the TGF-$\beta$ types I, II, and III. It is now known that a wide variety of human pathology can be caused by aberrant expression and function of these receptors. the coding sequence of the type II receptor (RII) appears to render it uniquely susceptible to DNA replication errors in the course of normal cell division. By virtue of its key role in the regulation of cell proliferation, TGF-$\beta$ RII should be considered as a tumor suppressor gene. High levels of mutation in the TGF-$\beta$ RII gene have been observed in a wide range of primarily epithelial malignancies, including colon and gastric cancer. It appears likely that mutation of the TGF-$\beta$ RII gene may be a very critical step in the pathway of carcinogenesis.

A theoretical investigation of the solid-phase mechanochemical synthesis of nano-sized target product on the basis of dilution of the initial powdered reagent mixture by another product of an exchange reaction is presented. On the basis of the proposed 3-mode particle size distribution in mechanically activated mixture, optimal molar ratios of the components in mixture are calculated, providing the occurrence of impact-friction contacts of reagent particles and excluding aggregation of the nanosized particles of the target reaction product. Derivation of kinetic equations for mechanochemical synthesis of nanoscale particles by the final product dilution method in the systems of exchange reactions is submitted. On the basis of obtained equations the necessary times of mechanical activation for complete course of mechanochemical reactions are designed. Kinetics of solid phase mechanosynthesis of nano-TlCl by dilution of initial (2NaCl + $Tl_2SO_4$) mixture with the exchange reaction product (diluent, $zNa_2SO_4$, $z=z^*=11.25$) was studied experimentally. Some peculiar features of the reaction mechanism were found. Parameters of the kinetic curve of nano-TlCl obtained experimentally were compared with those for the model reaction KBr + TlCl + zKCl = (z + 1) KCl + TlBr ($z=z_l^*=13.5$), and for the first time the value of mass transfer coefficient in a mechanochemical reactor with mobile milling balls was evaluated. Dynamics of the size change was followed for nanoparticle reaction product as a function of mechanical activation time.

Recurrent Bell's palsy is a very rare case and have been reported that shows the incidence to be approximately 10 per cent in the Bell's palsy patents. It is generally accepted that facial paralysis caused by compression of the facial nerve by tumor develops slowly and has an unremitting course, however, reported cases have described the rare association of recurrent facial paralysis and intracranial tumor, and the same recovery rate. Usual symptoms of Bell's palsy include subacute facial palsy, hyperacusis on the affected side, postauricular pain on the affected side, altered sensation of taste, and partial trigeminal distribution hypesthesias. Complete resolution of symptoms is usually seen in 2-3months in $75-85\%$ of cases, with $25-35\%$ showing varying degrees of residual effects. We report a case of 4th ipsilateral recurrent Bell's palsy in a 14-year-old women, which was occurred in every winters. We treated her with acupuncture, moxibustion, herbal medication, carbon and silver spike point, and used House-Brackmnn grading system(HBGS) and the Fisch Detailed Evaluation of Facial Symmetry(DEFS) to assess the degree of paralysis in each part of face.
