In this paper, we investigated Ba-construction, anti-passive voice and passive voice. Although Yeh & Pan(2012) were meaningful in that they provided new perspectives on Ba-construction, there were problems to reconsider. Yeh & Pan regarded Ba-construction as a kind of anti-passive construction and said it was de-transitivized, but Ba-NP was not demoted, which was originally placed before verb and that construction is still a high-transitive construction. They also said that there are some cases where Ba-NP are indefinite, but in this case Ba-NP still has definite meanings with the help of other factors, such as main verb and context. In addition, in some cases of ‘BageNP’ the ‘ge’ played a role in highlighting quality or attribute rather than the function of indicating definite and indefinite The decisive reason for not seeing Ba construction as an anti-passive construction lies in the fact that the demoted object of an anti-passive construction can be deleted, while the Ba-NP must never be deleted in any case. Meanwhile, Ba-construction and Bei-construction had many things in common and have been discussed together by many scholars. However there are also many differences between two constructions, because the operating mechanism itself is different. Therefore, we thought Ba-construction is still a kind of active voice construction, some non-disposal examples are directly related to causative voice(zhishi), and anti-passive and passive voice are only indirectly related with this construction. In particular, anti-passive voice can be said that it is almost opposite from Ba-construction.

차체 경량화를 위한 Al7075-T6와 SPFC590DP 이종소재 접합 공법에 따른 접합부 성능 비교 연구

The necessity of dissimilar joining between aluminum alloy and steel is increasing in order to meet the demand for weight reduction in automobiles. However, dissimilar joining between 7000 series aluminum alloy and steel is challenging with mechanical joining methods such as self-piercing rivet(SPR) and flow drill screw(FDS) without hole processing. In this study, mechanical performances of dissimilar joints between 3 mm thick Al7075-T6 and 1 ㎜ thick SPFC590DP were evaluated for use in lightweight B-pillar assembly. Self-Piercing Rivet(SPR) and Flow Drill Screw(FDS) with one-hole processing, bolt/nut and blind rivet with two-hole processing and adhesive bonding were compared with respect to joint performance. In SPR joining, rivet did not penetrate and rivet buckling occurred in the rivet due to the thickness and high strength of the Al7075-T6. By processing pre-hole on Al7075-T6 and applying an additional Al5052-H32 sheet to induce mechanical interlock in SPR joint, it became possible to join Al7075-T6 to SPFC590DP with an SPR. The tensile shear load of the SPR joint was 9.8 kN. In FDS joining, it is also necessary to process pre-hole on Al7075-T6 since the fastener could not penetrate the Al7075-T6. The tensile shear load of the FDS joining was 8.1 kN. In bolt/nut and blind rivet joining, the tensile shear load were measured respectively 11.1 kN and 5.2 kN. In adhesive bonding with 1K glue, the tensile shear load was measured 18.5 kN when the interfacial surface was roughened with a sand paper.

본 연구에서는 가물치(Channa argus) 추출물의 신경세포 분화와 산화 스트레스에서의 효능을 분석하기 위하여 녹차와 효소를 이용한 다양한 추출 방법(상온 추출물, RE; 녹차 상온 추출물, GRE; 효소 상온 추출물, ERE; 녹차 효소상온 추출물, GERE)을 사용하여 제조 된 추출물의 아미노산 조성과 항산화 활성을 비교 분석하였고, 신경성장인자(NGF) 유도 신경세포 분화 및 과산화수소 처리에 의해 유도된 PC12 세포 독성에 대한 보호효과를 규명하고자 하였다. 총 아미노산 함량은 RE 및 GRE보다 효소 추출물인 ERE 및 GERE에서 훨씬 더 높았다. 효소 가수 분해물 (ERE 및 GERE)에서 ABTS 라디칼 소거 활성은 RE 및 GRE보다 높았다. 또한, RE와 ERE는 PC12 세포에서 neuronal growth factor (NGF) 매개 신경 돌기 성장뿐만 아니라 growth associated protein (GAP)-43 및 synapsin-1의 발현을 현저하게 향상 시켰다. 과산화수소(H₂O₂)에 의해 손상된 PC12 세포에 4가지 유형의 Channa argus 추출물을 첨가 한 후 PC12 세포의 생존율을 측정하였다. PC12 세포의 생존율은 RE, GRE, GERE에서 각각 77.5±1.9%, 84.0±0.8%, 81.1±0.9%이였다. 이러한 세포 생존율은 H₂O₂ 만을 처리 한 음성 대조군(70.0±2.0%)에 비해 더 높았다. H2O2 처리에 의해 유도 된 세포 독성도 RE, GRE 및 GERE 처리에 대한 반응으로 상당히 완화되었다. 종합하면, Channa argus 추출물은 산화 스트레스와 신경 손상을 감소시키는 기능성 물질로 유용하다는 것을 시사하며, 향후 이들 소재를 활용한 다양한 기능성 제품의 개발이 필요할 것으로 판단된다. The present study provides in vitro evaluations of snakehead (Channa argus) extracts on neuronal cell differentiation and oxidative stress. This study was conducted to analyze the constituents of the extracts prepared using different extraction methods (room temperature extract, RE; green tea room temperature extract, GRE; enzyme room temperature extract, ERE; green tea enzyme room temperature extract, GERE) and to compare their biochemical properties. The contents of total amino acids in ERE and GERE were much higher than RE and GRE from Channa argus. ABTS radical scavenging activities in enzymatic hydrolysates (ERE and GERE) were higher than those of RE and GRE. In addition, RE and ERE caused a marked enhancement of the nerve growth factor-mediated neurite outgrowth from PC12 cells and the expressions of growth-associated protein (GAP)-43 and synapsin-1. Four types of Channa argus extract were added to PC12 cells damaged by hydrogen peroxide (H₂O₂), after which the survival rate of PC12 cells was measured. The survival rates of PC12 cells were 77.5±1.9%, 84.0±0.8%, 70.4±1.5%, and 81.1±0.9% at RE, GRE, ERE, and GERE, respectively. These cell survival rates were higher than that of the negative control group (70.0±2.0%) treated only with H₂O₂. Cellular toxicities induced by treatment with H₂O₂ were also significantly alleviated in response to treatment with RE, GRE, and GERE. Taken together, these results suggest that Channa argus extracts are helpful as a functional material to decrease oxidative stress and neuronal damage.

‘호(好)+V’ 구문에 관한 소고 ― ‘호(好)+V’ 구문과 ‘기래(起来)’ 구문의 대칭과 비대칭

曺京煥 ( Cho Kyunghwan ) 중국어문연구회 2020 中國語文論叢 Vol.0 No.101

In this paper, we investigated the status of the ‘Hao+V’ construction. Firstly, we reviewed at the differences between Tough construction and Middle construction, and also looked at the differences between ‘Hao+V’ construction and ‘Rongyi/Nan’ construction. In previous studies, ‘Hao+V’ construction and ‘Rongyi/Nan’ construction were identified and treated differently from middle construction. However, in this paper ‘Hao+V’ construction is different from ‘Rongyi/Nan’ construction, the former is more Middle Construction and the latter is more Tough Construction. In addition, ‘Hao+V’ construction itself was divided into Non-Middle concstruction and Middle construction which was also seen in ‘Qilai’ construction. The formation process creates an asymmetrical relationship between ‘Hao+V’ construction and ‘Qilai’ construction. the former has been changed from Middle to Non-Middle, whereas ‘Qilai’ Construction has been changed from Non-Middle to Middle. Although ‘Qilai’ Construction is the most frequently mentioned in discussing Chinese middle construction today, from a view of historical process, it is highly likely that ‘Hao+V’ construction has influenced ‘Qilai’ Construction. In addition, we hope we will be able to better understand the characteristics of Chinese middle construction through research on the other related constructions.

Animacy is the most important factor in changing voices of the constructions. During the process of changing voices, for example, from disposal to causative and from shiyi to passive, subject was deleted and producted pragmatical effects because of the change of animacy of the construction. But in the one Causative voice, from shiyi to causative, above the phenomena was not producted.

Passive construction is the common construction across languages. The purpose of this article is how western missionaries treated these constructions several hundred years ago. In the 17th and 18th centuries Martino Martini and Francisco Varo simply mentioned Bei construction and Wei construction. In the 19th centuries, Josheph Henry Premare, Robert Morrison, William Lobscheid explained other passive constructions. But among the western missionaries Karl Friedrich Gutzlaff’s analysis on Chinese Passive Constructions is remarkable. Furthermore he noticed Gei passive Construction for the first time. Joseph Edkins analyzed Jiao construction in the same way. In brief Western missionaries relatively early notice on Chinese Passive Constructions and their analysis reflect language situation in modern times.
