정지형(Jung, Ji-Hyung)(鄭智馨),김형근(Kim, Hyung-Geun)(金亨根) 대한중국학회 2020 중국학 Vol.73 No.-

제주의 대중 수출은 2018년 기준 2,283만 달러로 연평균 38% 씩 증가하고 있는 실정이나. 수출액은 타 지자체에 비해 미미한 수준이다. 본 연구에서는 대중 수출을 위한 제주 상품의 경쟁력 분석을 위해 제주산 주요 수출 품목군 선정과 함께 우선 순위를 도출하고자 하였다. 이는 향후 제주의 대중 수출에 대해 행정적인 측면에서도 선택과 집중을 통해 수출을 활성화하기 위함이다. 본 연구에서는 무역특화지수와 시장비교우위지수를 활용하여 제주의 대중 수출 경쟁력을 분석하였으며, 제주의 수출 성장에 대한 주요 품목별 대중 수출 기여도를 산출하였다. 또한 상기 분석된 무역특화지수와 시장비교우위지수, 수출 기여도를 통해 Z-SCORE 가중치를 적용하여 제주지역의 대중 수출 우선순위 품목을 선정하였다. 연구결과 기초화장품(330499) 제1위, 소주 등 증류주(220890) 제2위, 기타혼합주스(200990) 제3위, 감귤류과실(200830)제4위, 기타녹차(미발효)(090220) 제5위, 기타조제식품류(210690) 제6위, 기타어종-갈치(030389) 제7위, 기타당류제품(170490) 제8위로 나타났다. In 2018, the amount of Jeju‘s export to China added up to 22,830,000 dollars, and it has been increasing at an average of 38% every year. However, it is at a far lower level when compared to that of other local government in Korea. This study aims at selecting and prioritizing the major export items produced in Jeju, so that the competitiveness analysis of the products exported to China could be carried out. The results of analysis will be used to activate the exports to China even in administrative aspect through selecting and concentrating on promising items. In this study, the export competitiveness has been analyzed by using of the Trade Specialization Index and Market Comparative Advantage Index, and the rate of contribution of each major item to the Jeju’s export growth has been calculated, as well. In addition, the Jeju region s priority items exported to China have been selected by assigning the weighted Z-score on the basis of the Trade Specialization Index and Market Comparative Advantage Index mentioned above. The results of this study show that basic cosmetics take the first place(330499), followed by hard liquors such as ‘Soju’(220890), mixed juice(200990), orangescitrus fruits (200830), other green tea (non-fermented)(090220), other delicatessen food(210690), other fishes-cutlassfish(030389), and other sugar-based foods(170490), in order of priority.

High-Resolution NMR Spectroscopy for the Classification of Beer

정지호,조성진,김용애 대한화학회 2017 Bulletin of the Korean Chemical Society Vol.38 No.4

High-resolution Nuclear Magnetic Resonance (NMR) spectroscopy has many applications in the analysis of food and beverage products, especially in combination with multivariate analysis. Most studies have focused on the composition, raw materials, geographical origin, and quality control of these products. Since the1H NMR spectrum of beer contains huge water and ethanol resonances with higher signal intensities of them than those of the compounds of interest, it becomes problematic to assign a spectrum. So, these obstacles must be overcome in order to define chemical components in beer and to analyze or obtain meaningful data. In this paper, we will analyze the 1H NMR spectra of different lagers and ales with principal component analysis (PCA) and partial least squares (PLS) methods. The results of multivariate analysis of 1H NMR spectra of lyophilized and raw samples obtained using a standard solvent suppression pulse program are compared and discussed for more exact technique as an informative quality control tool.

학습자의 흥미가 교사의 교수의도와 다를 때: 유아의 학습의도와 학습결과에 대한 예측

정지인(Jeein Jeong) 한국아동학회 2020 아동학회지 Vol.41 No.5

Objectives: The current study aimed to investigate how young children predict a learners learning intention and outcome when given information about the presence of the learners interest in knowledge and a teachers teaching intention. Methods: Participants included 59 children aged between 3 to 5-years old. After hearing stories designed to share information about a learners interest in knowledge and a teachers teaching intention, the children were asked to predict whether the learner would try to learn and whether he could learn successfully. The children’s theory of mind was also measured. Results: Children predicted that the learner would try to learn when he was interested in knowledge but not when he did not have an interest in it. Also, in comparison to 3- and 4-year-olds, 5-year-olds more frequently predicted the learner could not learn successfully if he was not interested in knowledge even if the teacher taught. Conclusion: Young children tend to weigh a learners interest in knowledge more than a teachers teaching intention to predict the learners motivation to learn. Also, as they age, they consider the learners interest in knowledge more seriously to predict the success of learning.

First Korean Record of Porcellanopagurus japonicus (Decapoda: Paguroidea), a Hermit Crab Living in Bivalve Shells

정지범,이상희 한국동물분류학회 2020 Animal Systematics, Evolution and Diversity Vol.36 No.4

This study reports the pagurid hermit crab Porcellanopagurus japonicus in Korean waters for the first time. This species has a right cheliped larger than the left one, reduced and globular abdomen, and symmetrical uropods. Porcellanopagurus japonicus is similar to P. nihonkaiensis, a previously reported congeneric species in Korea, but also has distinguished morphological and ecological characters. There are currently issues with the Korean scientific name for P. japonicus, we suggest a reasonable Korean scientific name of this organism with its etymology. In addition, this species inhabits bivalve shells, which is not a typical habitat for hermit crabs, and the unique habitats of this and several other Korean hermit crabs are reviewed.

Technology Readiness and Self Checkout Service Adoption in Korea

정지복 충남대학교 경영경제연구소 2022 경영경제연구 Vol.44 No.1

As more consumers prefer zero contact services, self-service technologies using advanced technologies are being actively introduced in the retail industry. Among various self-service technologies, self checkout service is being introduced at large supermarkets and convenience stores where consumers can calculate themselves. In this paper, we apply the TRAM constructs to the use and adoption of self checkout application in the retail industry. Studies have shown that optimism and innovativeness have a significant effect on perceived ease of use, and perceived ease of use has mediated effect between optimism, innovativeness and intention to use. However, discomfort and insecurity were found not to have significant effect on perceived ease of use. Consumers seeking optimistic and innovative thinking recognize that self checkout service is not difficult, easy to learn, and can be used without the help of employees. In addition, discomfort and insecurity in advanced technology do not significantly affect the convenience of the self checkout process. Future studies will require ongoing research on whether the results of this study differ in unattended checkout user characteristics or situational variables

정지열,김낙형,임소정,홍경화,박자실,김재훈 한국임상수의학회 2021 한국임상수의학회지 Vol.38 No.2

Two 11-year-old cats, female Korean shorthair cat and male Siamese cat, with abdominal distention were presented to the local animal hospitals. Radiographic and ultrasonographic examinations revealed moderate to severe splenomegaly in both cats. In Korean shorthair cat, multiple masses were also existed on the anal and facial skin. Surgically excised whole spleens of two cats were requested for histopathologic examination. Histopathologically, numerous neoplastic round cells with cytoplasmic fine granules were widely infiltrated in the splenic parenchyma. The cytoplasmic granules were metachromatic on toluidine blue staining. These splenic masses were diagnosed as splenic mast cell tumors. Among them, Korean shorthair cat was remained healthy for at least 1 year after splenectomy. Because of no visiting of owner, we were only able to know the information for Siamese cat until 10 months after the splenectomy. To our best knowledge, this is the first detail case reports for splenic mast cell tumors in cats in Korea.

정지양,왕어원,왕윤동 한국콘텐츠학회 2020 한국콘텐츠학회논문지 Vol.20 No.11

Political connection are widespread in many countries and are a hot topic in economic research right now. In China, companies are actively forming political connections in several ways. Based on the research model and theoretical analysis, this thesis puts forward the research hypothesis and constructs the research model of political connections and corporate performance using the financial data and corporate governance data of China A-share listed real estate companies in 2010-2014. The thesis mainly analyzes the political association of CEO. For the analysis result, this research uses the univariate regression analysis and multivariate analysis to carry out the robustness test. The empirical study analysis includes three parts: firstly, in Chinese listed real estate enterprises, CEO political connection has a significantly negative correlation with corporate performance. It means real estate enterprises whose CEO has political connections gain a lower performance than other enterprises; Secondly, from the personal characteristics of the CEO, age, sex and education level have positive relationship with the performance of the enterprise, the additional post situation negatively related to the firm's performance; Finally, the firm's scale liquidity ratio and capital asset rario have a negative relationship with corporate performance, and the number of top managers is positively related to corporate performance. This research made a study on the political connection in Chinese real estate industry, which could also provide beneficial references for the development of enterprises in this industry.

정지인(Jiin Jeong),배수영(Suyeong Bae),유은영(Eun-Young Yoo),홍익표(Ickpyo Hong) 대한신경계작업치료학회 2023 재활치료과학 Vol.12 No.1

목적 : 본 연구에서는 빅데이터를 통해 정신과 질환을 가진 노인의 생활 습관 행태와 의료비 지출 크기간의 연관성을 분석하여 생활 습관의 긍정적 영향 및 중요성을 제시하고 이에 관련한 중재의 근거를제언하고자 하였다. 연구방법 : 건강보험공단에서 제공하는 노인 코호트 데이터베이스(Database; DB)의 2014, 2015년 자료를활용하여 이차데이터 분석을 시행하였다. 연구 목적에 따라 전체 변수 중 생활 습관 행태와 연간 의료비지출 크기를 추출하였다. 각각의 생활 습관 행태와 연간 의료비 지출 크기 사이의 연관성은 일반선형모형(Generalized linear model)을 사용하여 분석하였다. 결과 : 선정기준에 따라 추출된 총 32,853명의 데이터가 분석에 사용되었다. 12,617명(38.40%)의 남성과20,236명(61.60%)의 여성으로 구성되어 있었다. 생활 습관과 의료비의 연관성을 분석한 결과, 비흡연자의 경우 흡연자보다 의료비 지출이 유의하게 낮았으며(estimate = -218,255원, p = .037), 일주일 중30분 이상 걷는 일수가 증가할수록 의료비 지출이 유의하게 감소하였다(estimate = -58,843원, p < .0001). 반면, 일주일 중 술을 마시는 일수가 감소할수록 의료비 지출이 증가하는 양상이 나타나는결과가 도출되었다(estimate = 692,289원, p < .0001). 결론 : 본 연구는 정신과 질환을 가지고 있는 노인에게 있어 생활 습관의 행태에 따른 의료비의 변화를분석하였다. 흡연과 운동은 의료비 지출과 음의 연관성을 나타냈으며 걷기 운동을 많이 할수록, 흡연을하지 않을수록 의료비 지출이 감소함을 알 수 있었다. 이러한 결과는 정신과 질환을 가지고 있는 노인에게 있어 건강한 생활 습관의 중요성을 시사한다. 본 연구가 정신과 질환을 가진 노인의 신체적, 정신적건강 증진을 위한 생활 습관 관리 프로그램의 임상적 근거로써 활용될 수 있기를 기대한다. Objective : This study aimed to analyze the association between lifestyle and medical expenses of older adults with mental illness using claims data. Methods : We conducted secondary data analysis using the older adult cohort database provided by the Korea National Health Insurance Service. The lifestyle and medical expense variables were extracted from the cohort database. We used a generalized linear model to examine the association between lifestyle and medical expenses. Results : In total, 32,853 records were extracted. The results showed that smokers had medical expenses (estimate = -218,255, p = .037). As the number of days of walking increased, medical expenses significantly decreased (estimate = -58,843, p < .0001). Furthermore, as the number of days of drinking decreased, medical expenses increased (estimate = 692,289, p < .0001). Conclusion : This study analyzed the estimates of medical expenses according to lifestyle among older adults with mental illness. Smoking and exercise were negatively associated with medical expenses. These results suggest the importance of a healthy lifestyle for older adults with mental illness. In addition, this study can be used as clinical evidence for lifestyle management programs to improve physical and mental health.
