SMEs’ Digital Transformation Competencies on Platform Empowerment
Sun A MIN1,Bo Young KIM2 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.6
Small- and medium-sized enterprises (SMEs) are strengthening their digital transformation strategies with new values on creative technologies and reorganized business models and processes in the ever-changing digital economy. In line with the changes in business environments based on digital platforms’ ecosystem, they put forth efforts into strengthening corporate platforms. Accordingly, the study aims to clarify the effects of SMEs’ digital transformation competencies on platform empowerment with platform development strategy and envelopment strategy as mediating factors. Notably, among the four platform factors that enterprises require, namely, unique competency strengthening, shared value creation, cost-saving effect, and network effect, this study analyzes which factors are more significantly affected by digital transformation competencies and platform strategies. To this end, study hypotheses were tested based on the survey conducted among 361 SME executives and employees in South Korea. In conclusion, it turned out that SMEs’ digital transformation competencies positively affected both platform development strategy and envelopment strategy. However, platform envelopment strategy affected all of the factors of platform empowerment, while development strategy did not affect them. Thus, it was verified that SMEs’ digital transformation competencies could affect platform empowerment through envelopment strategy more than platform development strategy.

Vasculitis is a heterogeneous group of diseases that destroy blood vessel walls by inflammation. Approximately half of vasculitis cases are idiopathic, but sometimes associated with genetic factors, medicines, chronic infection, autoimmune diseases, and malignancies. Although the mechanism remains unclear, vasculitis secondary to malignancy, also known as paraneoplastic vasculitis, has been reported. It is generally associated with hematologic malignancies rather than solid malignancies and commonly presents as leukocytoclastic vasculitis or polyarteritis nodosa. We experienced a case of leukocytoclastic vasculitis in a patient with hepatocellular carcinoma and membranous obstruction of the inferior vena cava. Here, we report this case with a brief review of literature. (J Rheum Dis 2015;22:322-326)

Purpose: The purpose of this study is to determine the status of nodal disease, including the right paraesophageal node, in papillary thyroid carcinoma (PTC). Methods: A total of 116 patients with PTC underwent total thyroidectomy and prophylactic central node dissection, including right paraesophageal lymph nodes (RPE LNs). Metastases to RPELNs were analyzed by site and clinicopathologic variables. Recurrence rate and post-operative complications were also evaluated by comparing the right paraesophageal lymph node dissection (RPE LND) with the non-RPE LND group. Results: Central node metastases were detected in 57 (49.1%) patients; paratracheal and pre-tracheal lymph node metastases, total RPE LN metastases, and metastases only in RPE LN occurred in 50 (43.1%), 18 (15.5%), and 5 (4.3%) patients, respectively. Age, tumor size, tumor longitudinal location, extrathyroidal extension, and multicentricity were insignificant in RPE LN metastasis (P>.05). Although there was no significant statistical difference, tumors with lymphatic invasion and larger tumors (>1 cm) had more frequent RPE LN metastases. RPE LN metastases were frequent in deeply located tumors instead of superficially located tumors (P=0.015). Compared with the non-RPE LND group, the incidence of post-operative complications (transient hypocalcemia and vocal cord palsy) was not significantly different and there was no recurrence in both groups during the follow up period. Conclusion: The metastatic rate of the right paraesophageal lymph nodes was 15.5%; 83.3% of these were macrometastatic. Prophylactic RPE dissection compared with the non-RPE LND group, however, did not show a survival difference for 5 years.

Purpose: The clinical value of macrocalcifications as an indicator that predicts malignancy of thyroid nodules is controversial. The purpose of this study was to investigate additional ultrasonographic findings accompanying macrocalcifications for predicting malignancies in thyroid nodules. Methods: Between January 2005 and April 2008, 315 patients who had thyroid nodules with FNAB resulting in suspicious malignancies underwent thyroidectomy at the Wallace Memorial Baptist Hospital. Three hundred fifteen nodules, which were confirmed to be papillary thyroid carcinoma, and 192 nodules, which were confirmed to be benign, were reviewed retrospectively. We analyzed the malignancy rates according to calcification patterns and US findings of the associated solid nodules. Results: Among the 165 papillary thyroid carcinomas with microcalcifications, 161 accompanied solid nodules, and 4 were found with microcalcifications, but without solid nodules. Of the 161 papillary thyroid carcinomas with microcalcifications and solid nodules, 85.7% showed signs suggestive of malignancy. The remaining 14.3%, where only microcalcifications were present, showed indications of predicting malignancy. When solid nodules were found with macrocalcifications, there were indicators of predicting malignancy (100%). Also, for situations in which benign nodules were accompanied by solid nodules, 29% had signs of predicting malignancy. For situations in which benign nodules did not accompany solid nodules, 21% showed suspicious signs of predicting malignancy, but were all confirmed as benign. Conclusion: For nodules that accompany microcalcifications, there can be indicators that predict malignant conditions separate from other opinions that accompany microcalcifications. However, for macrocalcifications, it would be more effective to set up future treatment plans based on ultrasonographic features of solid nodules accompanying calcifications rather than the calcification itself.

The leaf beetle, Chrysolina aurichalcea (Coleoptera: Chysomelidae), is a pest damaging plants of Compositae. In order to understand the genetic diversity and geographic variation we sequenced a portion of mitochondrial COI gene (658 bp) and complete nuclear internal transcribed spacer 2 (ITS2) of the species collected from seven Korean localities. A total of 17 haplotypes (CACOI01~CACOI17), with the maximum sequence divergence of 3.04% (20 bp) were obtained from COI gene sequence, whereas 16 sequence types (ITS2CA01~ITS2CA16), with the maximum sequence divergence of 2.013% (9 bp) were obtained from ITS2, indicating substantially larger sequence divergence in COI gene sequence. Phylogenetically, the COI gene provided two haplotype groups with a high nodal support (≥87%), whereas ITS2 provided only one sequence type group with a high nodal support (≥92%). The result of COI gene sequence may suggest the presence of historical biogeographic barriers that bolstered genetic subdivision in the species. Different grouping pattern between COI gene and ITS2 sequences were interpreted in terms of recent dispersal, reflected in the ITS2 sequence. Finding of unique haplotypes and sequence types only from Beakryeng-Islet population was interpreted as an intact remnant of ancient polymorphism. As more samples are analyzed using further hyper-variable marker, further fruitful inference on the geographic contour of the species might be available.
