Aging aircraft structures are inevitably exposed to environment for a long time facing many potential problems, including corrosion and wide spread fatigue damage, which in turn cause the degradation of flight safety. In this study, the environmental surface damages on aging aircraft structures induced during service were quantitatively analyzed. Additionally, S-N fatigue tests were performed with center hole specimens extracted from aging aircraft structures. From the results of quantitative analyses of the surface damages and fatigue tests, it is concluded that corrosion pits initiated during service reduce the fatigue life significantly. Finally, using the fracture mechanics and the EIFS (equivalent initial flaw size) concepts, the remaining fatigue life was predicted based on actual fatigue test results.

말뭉치 자료에 근거한 ‘是…的’ 분열구문의 유형과 동사의 상황유형 고찰

Based on the corpus data, this paper analyzed various focus constructions of the cleft sentence ‘Shi…De’. The cleft sentences extracted from corpus data are classified into three major types as ‘O+Shi+XP+VP’, ‘S+Shi+XP+VP’, and ‘Shi+XP+VP’. According to the results of this analysis, the verbs with stronger feature of telicity and weaker feature of duration, can appear more freely in the cleft construction. In other words, the factors affecting the interpretation of the sentence with ‘Shi…De’ as a cleft construction are the two features, telicity and duration of the verbs. When a verb contains the feature of [+telic], it means that the internal structure of the verb necessarily includes a natural endpoint. The actions that these verbs mean are likely to be recognized as individual events. Therefore, when a telic verb appears in the form of ‘Shi…De’, it is always easily recognized as a single event that occurred in the past. On the other hand, when a verb contains the feature of [-telic], it does not include a natural endpoint, and except for non-durative active verbs that have no feature of duration, all include a certain duration section. The action that these verbs mean is not a single event, but is more likely to be recognized as a repetitive and habitual event. Therefore, the more durative feature a verb have, the more restricted the sentences is in its interpretation as a cleft construction.

This paper compared and analyzed the types of verbs and objects appearing in the construction ‘V+De(的)+Shi(是)+O’ and the construction ‘V+De(的)+O’. As a result of the analysis, the following differences were found in the situation types of verbs and the referentiality and thematic roles of objects appearing in the two constructions. First, all types of verbs can appear in the construction ‘V+De(的)+Shi (是)+O’, but in the case of the construction ‘V+De(的)+O’, verbs with telic property and verbs with less durative property generally appear. In other words, state situation types and the activity situation types with strong durative property are generally cannot appear in the the construction ‘V+De+O’. Second, both definite and nonreferential noun phrases can appear in the construction ‘V+De(的)+Shi(是)+O’ and the construction ‘V+De(的)+O’. However, in the case of an indefinite noun phrase, it can appear in the construction ‘V+De(的)+Shi(是)+O’, but it cannot appear in the construction ‘V+De(的)+O’. Third, if the object represents a patient, result, goal, location, it can appear in both constructions, and the object representing a instrument cannot generally appear in both constructions. In addition, in the case of the percept, agent and source argument, they can appear in the construction ‘V+De(的)+O’, but cannot appear in the construction ‘V+De(的)+O’. Therefore, it can be seen that the more transitive the typical object, the easier it is to be used as an object in the construction ‘V+De(的)+O’. Based on the analysis results above, it is judged that the construction ‘V+De(的)+Shi(是)+O’ and the construction ‘V+De(的)+O’ are different each other.

현대중국어 ‘S是V的O’와 ‘S是VO的’ 구문의 대조 분석
이은경 ( Lee Eungyeong ),공범련 ( Kong Fanlian ) 한국중국언어학회 2023 중국언어연구 Vol.- No.106
This paper analyzed the construction ‘S+Shi(是)+V+De(的)+O’ and the construction ‘S+Shi(是)+V+O+De(的)’. The analysis results are as follows. First, the state situation type verbs cannot appear in the construction ‘S+Shi (是)+V+De(的)+O’, but can appear in the construction ‘S+Shi(是)+V+O+De (的)’. When the state verb appears in the construction ‘S+Shi(是)+V+O+De (的)’, it functions as a verum-focus structure. Second, activity situation type verbs with strong durative property cannot appear in the construction ‘S+Shi (是)+V+De(的)+O’, but can appear in the construction ‘S+Shi(是)+V+O+De (的)’. When a strong durative verb appears in the construction ‘S+Shi (是)+V+O+De(的)’, it is interpreted as a nominalized sentence and functions as a predicate-focus structure. Next, when a less durative verb appears in the construction ‘S+Shi(是)+V+De(的)+O’, the tense of the sentence is interpreted as the past and functions as an argument-focus structure. And, a less durative verb generally cannot appear in the construction ‘S+Shi(是)+V+O+De(的)’, but can appear when S is a generic noun phrase, and in this case, the tense of the sentence is interpreted as the present and functions as a predicate-focus structure. In the case of semelfactive situation type verbs, they can appear in the construction ‘S+Shi(是)+V+De(的)+O’, but cannot appear in the construction ‘S+Shi(是)+V+O+De(的)’. In addition, when the semelfactive verbs appear in the construction ‘S+Shi(是)+V+De(的)+O’, the tense of the sentence is interpreted as the past and functions as an argument-focus structure. Third, acomplishment and achievment situation type verbs can appear in construction ‘S+Shi(是)+V+De(的)+O’, but cannot appear in the construction ‘S+Shi(是)+V+O+De(的)’. And, when two types of verbs appear in the construction ‘S+Shi(是)+V+De(的)+O’, the tense of the sentence is always interpreted as the past and functions as an argument-focus structure.

Perilla is an oilseed crop cultivated in Korea since ancient times. Due to the high α-linolenic acid content in perilla, perilla seed oil can easily become rancid. α-Linolenic acid is synthesized by two enzymes, endoplasmic reticulum-localized Δ15 desaturase (FAD3) and chloroplast-localized Δ15 desaturase (FAD7) in vivo. In order to lower the α-linolenic acid content of the seed oil without disturbing plant growth, we tried to suppress the expression of only the FAD3 gene using RNA interference, whilst maintaining the expression of the FAD7 gene. Seventeen transgenic plants with herbicide (Basta TM ) resistance were obtained by Agrobacterium-mediated transformation using hypocotyls of perilla plants. The transgenic plants were firstly confirmed by treatment with 0.3% (v/v) Basta TM herbicide, and the expression of FAD3 was measured by Northern blot analysis. The α-linolenic acid content was 10-20%, 30-40%, and 60% in two, seven, and three of the twelve T1 transgenic perilla plants which had enough seeds to be analyzed for fatty acid composition, respectively. Analysis of the fatty acid composition of T2 progeny seeds from T1 plants with the lowest α-linolenic acid content showed that the homozygous lines had 6-10% α-linolenic acid content and the heterozygous lines had 20-26% α-linolenic acid content. It is expected that the reduction in α-linolenic acid content in perilla seed oil will prevent rancidity and can be utilized for the production of high-value functional ingredients such as high γ-linolenic acid.

In the Standard Chinese, there are many sentences that contain multiple meanings while in the same form, such as the ‘O+Shi(是)+S+V+De(的)’. The noun phrase preceding the ‘Shi(是)’ is the object of the verb and the noun phrase between the ‘Shi(是)’ and the verb is the subject from the meaning perspective. Some scholars have interpreted the ‘O+Shi(是)+S+V+De(的)’ as ‘Shi(是)…De(的)’ construction, while others interpret it as a type of nominalized sentence. Still others have expounded that the form of ‘O+Shi(是)+S+V+De (的)’ is a double structure, which can be either the ‘Shi(是)…De(的)’ construction or nominalized sentence based on the context. Furthermore, the ‘O+Shi(是)+S+V+De(的)’ can either past tense or non-past tense, depending on the context. This study aims to identify under what context the ‘O+Shi(是)+S+V+De (的)’ can be recognize as either past tense or non-past tense, or recognized in both past and non-past tense. According to the analysis, the first factor of the effect on the tense of ‘O+Shi(是)+S+V+De(的)’ is the telicity. In case of the telic verbs of achievement and accomplishment situation type, the tense of the sentence is past. The second factor of the effect on the tense of ‘O+Shi (是)+S+V+De(的)’ is the durative property. Among the atelic verbs, the state situation type and the activity situation type with strong durative property, cannot appear in ‘O+Shi(是)+S+V+De(的)’. The activity situation type with less durative property can appear in ‘O+Shi(是)+S+V+De(的)’ sentences, and the tense can either be past or non-past depending on the context. The semelfactive situation type, which has no durative property, will only be past tense, should they appear in ‘O+Shi(是)+S+V+De(的)’.
