We have investigated a Korean literary magazine called Literature & Thought from the year 1972 to 2016 to study the introduction of the literature in Spanish in Korea. We`ve counted 148 articles in this magazine for 44 years. The results of this study are the followings: (1) We`ve the most articles published in 1975. (2) Countries with the most articles are Spain and Colombia. (3) Literature & Thought has introduced about 54 authors from the Spanish speaking world, where the writers of Spain were introduced more frequently and Gabriel Garcia Marquez has appeared more often. (4) This magazine does not focus on the Nobel laureates but on the introduction of the literature in Spanish from the point of world literature view. (5) Most writers of articles are Koreans. They are mostly professors of Spanish but we can find also a congress man and a professor of Russian literature. In the area of translation, the number of articles based on the English or French translation of Spanish works is higher than those ones dealing with the original literary works in Spanish. (6) The person who published the most articles is Min, Yong-tae, and he who provided the most articles about literary translation into Korean is Ahn, Junghyo. In conclusion, Literature & Thought has been introducing Spanish literature from the first issue to the general readers without prejudice in accordance with the status of writers and works. However, it is regrettable that articles in Spanish have not appeared in the last years.

The influence of microorganisms on the physical properties and strength of ilmenite and magnetite ores was determined in culture studies and laboratory tests of rock parameters such as absorption, porosity, elastic wave velocity, and uniaxial compressive strength. Initial pH condition was determined in the culture experiments, and then abiotic and biotic oxidation tests were performed to determine variations in pH, physical properties, and the strengths of the two ferruginous ore rocks. For ilmenite and magnetite ores, average initial values were, respectively, 0.185% and 0.496% for porosity, 0.046% and 0.123% for absorption, 1919 m/s and 1467 m/s for elastic wave velocity, and 432 MPa and 168 MPa for uniaxial compressive strength. The pH of ilmenite ore at the end of the abiotic and biotic oxidation tests was in the range of 3.82–4.26 and 2.20–2.57, respectively, while that of magnetite ore was 4.02–5.16 and 1.50–1.90, respectively. In magnetite ore, the changes in porosity and absorption due to the biotic oxidation test were larger than those observed in the abiotic oxidation test, while the variations in ilmenite ore due to both tests (abiotic and biotic oxidation) were small. The differences in porosity and absorption between the abiotic and biotic oxidation tests were larger in magnetite ore than in ilmenite ore, while the elastic wave velocity was smaller in magnetite ore than in ilmenite ore. In addition, the variations in uniaxial compressive strength due to the abiotic oxidation test were not significantly different than initial values in both ilmenite and magnetite ores, while variations caused by the biotic oxidation test were relatively large in both ferruginous ore rocks. Our results suggest that variations in the physical properties and strength of ilmenite and magnetite ores are largely dependent on microbial activity.

Friction stir welding (FSW) of thick Cu-Ni plate was successfully completed. The fracture position after tensile testing was located at the weld nugget zone (WNZ), where surface oxidation occurred. The oxidation morphologies on the surface of the base metal were analyzed by SEM, EPMA and XRD, with the oxide layer being obtained by simple and useful way to analyze the oxide products, namely, collecting oxide powders after immersing of the oxidized specimen into HNO3 solution. The results highlighted that an oxide layer of 30 μm thickness consists of a mixture of two phases, Cu2O and NiO, on the surface of the base metal. After FSW, the thickness of the oxide layer on the surface was decreased to approximately 5 μm, and broken oxide particles, which is NiO, penetrated into the WNZ by the rotating tool. NiO was preferentially formed at the surface after FSW because it has a lower Gibbs free energy value at 950 °C, which is the peak temperature measured during FSW. Oxide layer of Cu-Ni plate was clearly only removed by mechanical method grinding with 1200-grit SiC paper. The removal of oxide layer results in improved mechanical strength.

Depending on the unmanned level, this study derives the strategic factors for developing robot cafe services which are increasing significantly because of a combination of digital transformation and the COVID-19 pandemic. As a frame that combines UTAUT and SERVQUAL, and as a result of conducting the Delphi method through industry experts, the 8 top factors have been identified as performance expectancy, social influence, facilitating conditions, trust, ease of use, pleasure, satisfaction, and environmental factors. The18 sub-factors derived are utilization performance, untact, legal regulations, finances, technology, management environment organization, safety design, role responsibility, service stability, service safety, education manual, convenience, efficiency, pleasure by robots, emotions, quality, personalization, and environmental design factors. This study will present a wealth of practical implications to the entrepreneurs and corporate managers who start robot cafes on how to survive digital Darwinism brought about by digital transformation.

Purpose: To analyze and compare the results of robotic partial nephrectomy (RPN) at a single center with the previous large-scale studies in terms of perioperative and oncological outcomes. Materials and Methods: We retrospectively evaluated 1,013 cases of RPN in our center database from December 2008 to August 2018. Total 11 cases were excluded in final analysis. We evaluated perioperative outcomes as the Trifecta achievement, which is defined as no positive surgical margin (PSM), no perioperative complications greater than Clavien-Dindo classification I and a warm ischemia time of <25 minutes. In addition, we analyzed pathological and oncological outcomes; recurrence, metastasis, all-cause deaths, cancer-specific deaths, and 5-year survival rates. Results: In 1,002 cases, the Trifecta achievement was 61.1% (n=612). The postoperative complication was 18.4% (n=184) but most were grade 2 or less (14.9%, n=145). Ninety-three cases (9.28%) had benign and 907 cases (90.5%) had malignant pathologies. A local recurrence were 14 cases (1.54%) and distant metastasis were 20 cases (2.2%) during follow-up periods. All-cause death rate was 1.2% (n=11) and cancer-specific death rate was 0.2% (n=2). The median follow-up period was 39 months. A 5-year recurrence-free survival rate, cancer-specific survival rate, and overall survival rate were 95.2%, 99.7%, and 98.4%. Conclusions: In summary, our data shows comparable perioperative outcomes to other large-scale studies of RPN in terms of the Trifecta achievement with similar baseline characteristics. In terms of oncological outcomes, there was lower rate of PSM and similar recurrence free survival rate.

다양한 기능을 가지는 모바일 기기들이 하나로 융합되어 가는 방향으로 기술이 발전함에 따라, 음성 및 오디오 모두에 대해 우수한 음질을 제공하는 부호화 기술에 대한 요구사항이 증대되고 있다. MPEG 에서는 2008 년 10 월부터 MPEG-D USAC 기술에 대해 CfP 를 시작으로 본격적으로 표준화를 진행하고 있으며, 2011 년 3 월 96 차 미팅에서 Study on DIS 까지 승인하였다. 본 논문에서는 LPD 모드의 TCX 윈도우의 변경을 통한 USAC 성능향상 방법은 제안한다. TCX 프레임의 연결에 고정된 크기의 중첩만을 이용하는 현재의 방식과는 달리, 이전 TCX 모드와 다음 TCX 모드, transient 의 존재 유무에 따라 적절하게 TCX 윈도우 중첩 크기를 조절하여 음악 특성 신호에 대해 LPD 모드의 음질을 개선할 수 있다.
