Hazelnut plays a pivotal role in human nutrition and health due to its essential unsaturated fatty acids (FA). The composition of hazelnuts needs to be standardized in different regions for their mass production. In the present study, we compared the compositions of FA that are used as the index components in hazelnuts harvested from various provinces of Korea such as Gochang, Bonghwa, Hongcheon, and Cheorwon. This was also compared for each manufacturing process including raw material, degreasing, roasting, oil refining, and oil foil. The FA was extracted from the hazelnuts using Bligh-Dyer method, and was analyzed via gas chromatography-flame ionization detector (GC-FID). The results revealed that the hazelnuts in all regions comprised various types of unsaturated FA, such as oleic acid (C18:1), linoleic acid (C18:2), palmitic acid (C16:0), stearic acid (C18:0), eicosenic acid (C20:1), and linolenic acid (C18:3). Among these, the content of oleic acid, linoleic acid, and remaining FA was 76.8%–80.8%, 8.6%–11.5%, and 16%–18%, respectively. Thus, no differences were observed in the compositions of hazelnuts obtained from various regions. In conclusion, the unsaturated FA are an active ingredient in hazelnut that act as the major index component for developing functional healthy food.

U3Si2 판형핵연료판 우라늄 균질도 검사용 표준시편 제조를 위한 연구

송화영,박경민,김호민,김성환,정용진 대한기계학회 2024 大韓機械學會論文集A Vol.48 No.4

한국원자력연구원에서 제조하고 있는 U3Si2 판형핵연료판은 내부 우라늄 심재가 알루미늄 피복재로 덮여 있는 구조이며 다양한 비파괴검사 통해 완성한다. 그 중 X-ray 투과율을 수치적으로 표현한 gray level 값으로 판형핵연료판 내부 우라늄 영역의 균질도 검사를 진행하고 있다. 그러나 위 gray level이 X-ray의 미세한 변화와 실험실 내 환경적인 이유로 매번 조금씩 바뀌기 때문에 피검사물과 동시에 X-ray 촬영될 수 있는 별도의 표준시편이 필요하다. 따라서 본 연구에서는 감손 우라늄을 이용해 표준시편을 제작하였다. 모든 검사공정을 합격한 U3Si2 판형핵연료판 우라늄 심재영역의 평균 gray level과 가장 유사한 영역을 절단하여 제조하였다. 전자현미경(SEM) 분석을 통해 5.213 gU/cc U-loading량을 확인하였으며, 재검증을 통해 gray level 오차 수준을 기존의 5%에서 1%로 감소하는 효과를 확인하였다. The U3Si2 plate-type fuel plate manufactured by the KAERI has an internal uranium meat covered with an aluminum cladding and is completed via various non-destructive tests. The homogeneity of the uranium meat inside the U3Si2 plate-type fuel plate is inspected under the gray level expressed numerically based on the X-ray transmittance. Because the gray level changes gradually each time owing to slight X-ray changes and the environmental conditions in the laboratory, a separate standard that can be inspected simultaneously with the subject is required. In this study, a standard is produced using depleted uranium. The standard is manufactured by cutting an area whose gray level is the most similar to the average gray level of the uranium meat of a U3Si2 plate-type fuel plate that passes all inspections. Based on SEM analysis, 5.213 gU/cc of U-loading is confirmed, and the effect of reducing the gray level error from 5% to 1% is confirmed through retest.

현대중국어 동사 ‘打’의 다의성과 영상도식 변형 연구

송화영,김현철 중국어문학연구회 2023 중국어문학논집 Vol.- No.142

The purpose of this paper is to classify the polysemous verb ‘da(打)’ in Modern Chinese into its prototype meaning and extended meaning according to the prototype theory, and analyze the process of meaning extension by using the image schema of cognitive linguistics. This study shows the embodied image schema serves as the foundation for the semantic structure and the image schema transformation motivates semantic extension. This study finds that the verb ‘da(打)’ listed in the Modern Chinese dictionary has 24 meaning items, among which the prototype meaning is ‘hit’ and its 23 extended meanings form radial categories with the prototype as the reference point. They can be classified into 11 categories: hit, damage, attack, produce, change, direction, movement, acquisition, removal, bodily movement and manner. In addition, as structural elements that activate the image schema of the prototype meaning ‘force schema’, there are six main components: source of force, target of force, path of force, tool of force, intensity of force, and result of force. It is found that the transitivity decreased and non-prototypicality increased, as the transformation elements or the degree of transformation increased. It has been clarified that the image schema of the verb ‘da(打)’ and its transformations serve as motivating mechanisms for semantic extension through this study. This analysis also contributes to the understanding the polysemy of the Modern Chinese verb ‘da(打)’ and uncovering the dynamic linguistic phenomenon of infinite semantic expansion.

The decrease in the school-age population caused the closure of private universities, but the guidelines at closed private universities are ambiguous, causing confusion. Therefore, this study intends to suggest a plan to utilize the closed school university. The government aims to increase the possibility of selling closed schools by preventing alley slums through the recovery of alley commercial districts and local communities. The data were collected through a Google survey from September 30 to October 8, 2021 and an on-site interview conducted on October 2, 2021. A total of 84 nearby citizens of the closed school university were surveyed, and on-site interviews were conducted with a total of five people. The collected data suggested the direction of utilization plan for closed school building. This study will present a model for the use of closed school property in the future and contribute to the establishment of urban regeneration policies. 지방 소도시 쇠퇴에 따른 학령인구 감소는 사립대학의 폐교를 야기하며 관련 법령 및 지침이 모호하여 혼란을 겪고 있다. 이에 본 연구는 폐교대학의 활용방안을 제시하고자 한다. 대학 폐교로 경제적 어려움을 겪고 있는 골목상권과 지역공동체 회복을 통해 골목 슬럼화 방지를 통해 폐 교대학의 매각 가능성을 높이고자 한다. 자료는 2021년 9월 30일부터 10월 8일까지 구글 설문조사와 10월 2일 실시한 현장 인터뷰를 통해 수집하였다. 설문조사의 대상자는 폐교대학의 인근 시민 총 84명이었고, 현장 인터뷰는 폐교대학 출신 2명과 지역거주민 3명 총 5명과 진행하였다. 수집된 자료는 폐교 건물의 활용방안에 대한 도출방향을 제시하였다. 이 연구는 차후 폐교재산의 활용 모델을 제시하고 도시재생 정책의 수립에 기여 할 것이다.

현대중국어 ‘打+NP’ 구문의 결합가 관계와 의미 확장 연구

송화영,김현철 중국어문학연구회 2023 중국어문학논집 Vol.- No.143

The purpose of this paper is to analyze the valence relation and semantic expansion patterns of the Modern Chinese ‘da(打)+NP’ construction by using the theory of autonomy-dependence relation in cognitive grammar and the metaphoric and metonymic processes in cognitive semantics. The focus is on examining the polysemy of the verb ‘da(打)’. This study shows the meaning of the verb ‘da(打)’ is manifested within the construction and in the ‘da(打)+NP’ construction. The verb ‘da(打)’ exhibits a dependence structure, the noun object exhibits autonomy structure. The meaning of the verb ‘da(打)’ becomes elaborated and extended based on the type of noun object it combines with. Summarizing the research results: First, based on the 20 meaning items of the verb ‘da(打)’ in Modern Chinese dictionary, the prototype and extended construction of the ‘da(打)+NP’ construction are classified. As a result, they are categorized into 8 types: prototype construction [HIT]; extended construction [DAMAGE], [ATTACK], [PRODUCE], [CHANGE], [MOVE], [ACQUIRE], [REMOVE]. Second, the valence relation of prototype and construction ‘da1(打1)+NP’ are analyzed by using Langacker’s theory of autonomy-dependence relation. The results show that the verb ‘da(打)’ itself cannot activate meaning independently but gain elaboration based on the noun object it combines with. Third, based on the results of the valence relation in the prototype construction, the semantic expansion patterns of the extended construction ‘dax(打x)+NP’ are analyzed. The results show that the meaning of the prototype construction is elaborated and expanded through metaphor and metonymy. Fourth, building upon the analysis of the semantic expansion patterns of the ‘da(打)+NP’ construction, a network of semantic expansion is established, and the polysemous aspect of the ‘da(打)+NP’ construction is diagrammed. The results confirm that the polysemous aspect of the ‘da(打)+NP’ construction can be categorized into ‘horizontal polysemy’ and ‘vertical polysemy’. From a cognitive linguistic perspective, this study has elucidated the mechanism behind the polysemy of the verb ‘da(打)’ through the analysis of the ‘da(打)+NP’ construction. This analysis further enhances our understanding of polysemous verbs, which are abundant in Modern Chinese, and demonstrates the effectiveness of cognitive linguistic theories as tools for polysemy research.

Risk Factors of Cryptogenic Hepatocellular Carcinoma in Patients with Low Body Mass Index or without Metabolic Syndrome

송화영,이효근,이준성,김종연,임윤혁,송태준,배원기,김남훈,김경아 대한내과학회 2012 The Korean Journal of Internal Medicine Vol.27 No.1

Background/Aims: Many patients are diagnosed with cryptogenic hepatocellular carcinoma (HCC) without metabolic syndrome (MS). We investigated the risk factors for cryptogenic HCC in patients with a low body mass index (BMI) or without MS. Methods: Thirty-six patients were diagnosed with cryptogenic HCC over a 10-year period at a tertiary research hospital. Data including BMI score and risk factors for MS were analyzed retrospectively. Patients with fewer than two risk factors for MS (n = 16) were compared with those with two or more risk factors (n = 20). Patients with high BMI (≥ 23 kg/m2, n = 20) were also compared with those with lower BMI (n = 16). Results: Patients with fewer than two risk factors for MS were significantly more likely to smoke and be hepatitis B surface antibodies (anti-HBs)-positive vs. patients with two or more risk factors. However, only smoking was statistically significant on multivariate analysis. Peaks of BMI were observed in two regions. Lower BMI was significantly associated with the presence of anti-HBs compared with high BMI, although this association was not statistically significant on multivariate analysis. Conclusions: Smoking is a potential risk factor for cryptogenic HCC in patients without MS. Remote hepatitis B virus infection may be a risk factor for cryptogenic HCC in patients without MS or with a low BMI.

송화영,ZHUYUPENG,김지은,오정현,박한우 한국산학기술학회 2020 한국산학기술학회논문지 Vol.21 No.7

The purpose of present study is to identify the regional tourism resources using Webometric network analysis. The study focuses on Suseong area in Daegu metropolitan city. Various kinds of web-based data, for example, hit counts, online news, and public comments, were used to discover hot places and people's responses. The research question is, 'First, what is the optimum level of the search engine for suseong? Second, what is the online appearance of tourist resources in suseong? Which region is the center of tourism with high levels of emergence? Third, what are the main contents of news articles and comments related to the Suseong pond?'. The results show that the search engine optimization level in Suseong is lower than that in other areas in Daegu. In other words, tourism information and contents regarding Suseong are not highly visible on cyber space. Importantly, Suseong pond had the highest online presence. A close analysis of both online news and users' comments on Suseong pond, however, revealed the biggest concern as calling for improving public accessibility to tourism infrastructure. The findings are expected to contribute to policy development and service operation related to tourism resources in Suseong.
