Xue Jun DENG,박현재 한국무역상무학회 2022 貿易商務硏究 Vol.93 No.-

The main objective of this study is to identify the antecedents of the purchase intention of Korean millennial consumers on high involvement products made in China, focusing on the personal characteristics of the millennial consumers in Korea. 203 samples were finally used for this analysis using SPSS program. The results of the study are as follows ; First, Openness and extroversion in personal traits have positive (+) effect on customer satisfaction. Second, perceived social risk has been found to play a mediating role in the relationship between extroversion and customer satisfaction. Third, The customer satisfaction has positive (+) effect on purchase intention. As a result, companies which want to sell high-involvement products made in China are found to be effective in focusing on Korean millennial consumers with open personality characteristics and high levels of extroversion, when establishing marketing strategies in Korea. Furthermore, firms which want to sell high-involvement products made in China should also consider managing perceived social risk which plays a mediating role. 한국 소비자들은 보조배터리와 같은 저관여 중국산제품은 잘 구매하지만 노트북, 자동차와 같은 고관여 중국산 제품은 구매하기를 주저한다. 따라서 본 연구는 기존 선행연구의 한계점을 보완하고자 미래 소비의 중심으로 떠오를 한국 밀레니얼의 개인적 특성을 중심으로 고관여제품의 구매의도에 영향을 미치는 선행요인을 파악해보고자 하였다. 연구모형의 검증결과, 밀레니얼 소비자의 개방성과 외향성은 고객만족도에 유의한 영향을 미친다는 것을 알 수 있었다. 또한, 외향성과 고객만족도 사이에 지각된 사회적위험이 매개효과를 보이는 것으로 나타났다. 이상의 연구결과를 바탕으로 이론적, 실무적으로 유용한 시사점을 제시하고자 하였다.

Objective: To compare the positions of the mandibular premolars in Angle Class I subjects according to vertical facial type. The results will provide a theoretical basis for predicting effective tooth movement in orthodontic treatment. Methods: Cephalometric parameters were determined using cone-beam computed tomography in 120 Angle Class I subjects. Subjects were categorized as short, normal, and long face types according to the Frankfort mandibular angle. Parameters indicating the position of the mandibular right premolars and the mandible were also measured. Results: The angle between the mandibular first premolar axis and buccal cortex, the distance between the root apex and buccal cortex, angle of vestibularization, arc of vestibularization, and root apex maximum movable distance were significantly greater in the short face type than in the long and norm face types. The angle between the mandibular second premolar axis and buccal cortex, the distance from root apex to buccal cortex, and the arc of vestibularization were significantly greater in the short face type than in the normal face type. Conclusions: There are significant differences in the mandibular premolar positions in Class I subjects according to vertical facial type.

Objective: Patients with a history of ischemic stroke are at risk for a second ischemic stroke. This study aimed to investigate the relationship between carotid plaque enhancement on perfluorobutane microbubble contrast-enhanced ultrasonography (CEUS) and future recurrent stroke, and to determine whether plaque enhancement can contribute to risk assessment for recurrent stroke compared with the Essen Stroke Risk Score (ESRS). Materials and Methods: This prospective study screened 151 patients with recent ischemic stroke and carotid atherosclerotic plaques at our hospital between August 2020 and December 2020. A total of 149 eligible patients underwent carotid CEUS, and 130 patients who were followed up for 15-27 months or until stroke recurrence were analyzed. Plaque enhancement on CEUS was investigated as a possible risk factor for stroke recurrence and as a possible adjunct to ESRS. Results: During follow-up, 25 patients (19.2%) experienced recurrent stroke. Patients with plaque enhancement on CEUS had an increased risk of stroke recurrence events (22/73, 30.1%) compared to those without plaque enhancement (3/57, 5.3%), with an adjusted hazard ratio (HR) of 38.264 (95% confidence interval [CI]:14.975-97.767; P < 0.001) according to a multivariable Cox proportional hazards model analysis, indicating that the presence of carotid plaque enhancement was a significant independent predictor of recurrent stroke. When plaque enhancement was added to the ESRS, the HR for stroke recurrence in the high-risk group compared to that in the low-risk group (2.188; 95% CI, 0.025-3.388) was greater than that of the ESRS alone (1.706; 95% CI, 0.810-9.014). A net of 32.0% of the recurrence group was reclassified upward appropriately by the addition of plaque enhancement to the ESRS. Conclusion: Carotid plaque enhancement was a significant and independent predictor of stroke recurrence in patients with ischemic stroke. Furthermore, the addition of plaque enhancement improved the risk stratification capability of the ESRS.

Trichoderma spp. are widely applied, eco-friendly mycofungicides and plant growth promoters. Native Trichoderma strainsare likely to have more productive, stable biocontrol and biofertilizer activities since they are well adapted to the local environment. In this study, we isolated a native Trichoderma strain ‘Th62’ from the rhizosphere soil of wild Chelidonium majusplants in Harbin, China (126.6341°E, 45.7242°N). The isolated Trichoderma strain was identifi ed as a T. harzianum strainvia morphological observation and molecular methods based on the rDNA internal transcribed spacer region and elongationfactor-1α gene sequences. Signifi cant antagonistic activities of Th62 against fi ve soil-borne fungal phytopathogens,Fusarium oxysporum , Sclerotinia sclerotiorum , Alternaria alternata , Cytospora chrysosperma, and Rhizoctonia solani ,were confi rmed by dual-culture assays. Furthermore, the crude fermentation products of Th62 also displayed antifungalactivities against these fi ve pathogens. To evaluate the function of Th62 as a biofertilizer, we subsequently applied Th62on cockscomb ( Celosia cristata L), a plant species with both ornamental and medicinal values, by inoculation with Th62conidia at diff erent concentrations, 1 × 10 10 cfu mL −1 , 1 × 10 11 cfu mL −1 , and 1 × 10 12 cfu mL −1 . The benefi cial eff ects ofTh62 were evaluated by measuring the growth and photosynthetic traits of the inoculated cockscomb plants, and the resultsdemonstrated that Th62 signifi cantly improved the photosynthetic effi ciency, photosynthetic capacity, and the adaptabilityto intense light of the inoculated cockscomb plants compared to the controls. Consistently, Th62 inoculation signifi cantlyimproved the growth and fl ower yield of cockscomb. We presented a positive case of isolating and applying native microbialresources on local plantation practices.

Introduction: Reported prognostic roles of hypoxic inducible factor (HIF) expression in non-small cell lung cancer (NSCLC) have varied. This meta-analysis aimed to examine the relationship between HIF expression and clinical outcome in NSCLC patients. Methods: PubMed were used to identify relevant literature with the last report up to December $20^{th}$, 2012. After careful review, survival data were collected from eligible studies. We completed the meta-analysis using Stata statistical software (Version 11) and combined hazard ratio (HR) for overall survival (OS). Subgroup specificity, heterogeneity and publication bias were also assessed. All of the results were verified by two persons to ensure accuracy. Results: Eight studies were finally stepped into this meta-analysis in which seven had available data for HIF-$1{\alpha}$ and three for HIF-$2{\alpha}$. Combined HRs suggested that higher expression of $HIF1{\alpha}$ had a negative impact on NSCLC patient survival (HR=1.50; 95%CI=1.07-2.10; p=0.019). The expression of HIF-$2{\alpha}$ was also relative to a poorer survival (HR=2.02; 95%CI=1.47-2.77; p=0.000). No bias existed in either of the two groups. Conclusion: This study suggests that elevations of HIF-$1{\alpha}$ and HIF-$2{\alpha}$ expression are both associated with poor outcome for patients with NSCLC. The data support further and high quality investigation of HIF expression for predicting poor outcome in patients with NSCLC.
