  • The influences of Gallium doping on the magnetic microstructures and corrosion behaviors of Nd-Fe-B-Ti-C alloys are investigated. The cooling rate for obtaining fully amorphous structure is raised, and the glassforming ability is improved by the Ga addition. The High Resolution Transmission Electron Microscopy image shows that the ${\alpha}$-Fe and $Fe_3B$ soft magnetic phases become granular surrounded by the $Nd_2Fe_{14}B$ hard magnetic phase. The rms and $({\Delta}{\varphi})_{rms}$ value of Nd-Fe-B-Ti-C nanocomposite alloy thick ribbons in the typical topographic and magnetic force images detected by Magnetic Force Microscopy(MFM) decreases with 0.5 at% Ga addition. The corrosion resistances of $Nd_9Fe_{73}B_{12.6}C_{1.4}Ti_{4-x}Ga_x$ (x = 0, 0.5, 1) alloys are enhanced by the Ga addition. It can be attributed to the formation of more amorphous phases in the Ga doped samples.

  • The purpose of this study is to present a caddie education program that can improve the performance of golf caddies in China by comparing and analyzing the golf caddie education programs in South Korea and China. Caddie education programs were collected from 4 golf clubs, 3 professional caddie education institutions and 8 public institutions in South Korea and 6 golf clubs and 2 professional caddie education institutions in China. The following results were obtained. Although the caddie training in China is conducted over more time and term than in South Korea, it is necessary to have an education program considering golf expertise and quality of customer service. Therefore, the caddie education program in China is composed of golf related education(golf etiquette, golf practice skill), caddie duty training(safety management, customer service and image making), and training for caddie(fitness management, injury prevention, skin care, and cost-saving etc.). In the future, the Chinese golf club industry will has a potential to develop. In order to provide a consistent and systematic education, manual training on caddie education and training on caddie master to manage caddies should be conducted.

  • Fundus images can reflect ocular diseases and systemic diseases such as glaucoma, diabetes mellitus, and hypertension. Thus, research on fundus-detection equipment is of great importance. The fundus camera has been widely used as a kind of noninvasive detection equipment. Most existing devices can only obtain two-dimensional (2D) retinal-image information, yet the fundus of the human eye also has spectral characteristics. The fundus has many pigments, and their different distributions in the eye lead to dissimilar tissue penetration for light waves, which can reflect the corresponding fundus structure. To obtain more abundant information and improve the detection level of equipment, a snapshot nonmydriatic fundus imaging spectral system, including fundus-imaging spectrometer and illumination system, is studied in this paper. The system uses a microlens array to realize snapshot technology; information can be obtained from only a single exposure. The system does not need to dilate the pupil. Hence, the operation is simple, which reduces its influence on the detected object. The system works in the visible and near-infrared bands (550-800 nm), with a volume less than 400 mm × 120 mm × 75 mm and a spectral resolution better than 6 nm.

  • This paper selects 100 IT companies listed on the Shenzhen Stock Exchange from 2016 to 2020, and the public announcement in Hwajung collects ESG integrated ratings and grades for each sector and empirically verifies the relationship between ESG ratings and stock returns. Huazheng ESG level data and QIANZHAN database Using corporate financial data, a total of 500 samples were selected through correlation analysis and linear regression analysis with SPSS23 to analyze the effect of ESG on Return. As a result of the analysis, first, the impact on stock returns was found to be a significant positive (+) value for ESG integrated ratings and ratings by E (environment), S (social), and G (governance) sectors, confirming that ESG ratings have a positive mold of corporate stock returns. Currently, the world's major economies have proposed sustainable development strategies and "carbon neutral" goals. Development strategies are very consistent with ESG concepts, and companies that agree and execute ESG concepts may have higher ratings than other companies in the same industry, resulting in certain evaluation premiums. In addition, capital market performance in recent years shows that companies with ESG concepts or "carbon neutrality" concepts are generally considered to have higher growth potential and stronger anti-risk capabilities in the market. For listed companies, they should focus on ESG investment, improve ESG performance, and actively disclose related information to investors. Improving ESG performance should deliver positive information to society, enhance corporate image, increase market confidence in the future development of listed companies, and positively improve corporate value to actively increase financial, financial, trading, and other aspects of negotiation.

  • New year pictures prevailed from 1660s to 1860. Especially, the reign period of Emperor Qianlong(r. 1736-1795) was the period of prosperity. The period of 1660s when new year pictures were started to be popular was the reign period of Emperor Kangxi(r. 1662-1722) was just started and corresponded to Emperor Kangxi's promulgation of "Sacred Edict." Chinese operas such as Peking opera were very popular among common people in the period from 1660s to 1860 when new year pictures prevailed. Qing emperors as foreign ruler chose the way of ruling their people by means of cultural influence in stead of military power. However their culture effort was not efficient toward the majority of illiterate people. New year pictures offered every information about the world through visual icons to the illiterate people at that time who perceived the world by means of seeing. They met the world through visual information offered by new year pictures. New year pictures were the stronger visual medium to spread and educate "Sacred Edict" to illiterate subjects than any other guide books published by elite officers.

  • A fetoscope is an optical endoscope, which is often applied in fetoscopic laser photocoagulation to treat twin-to-twin transfusion syndrome. In an operation, the clinician needs to observe the abnormal placental vessels through the endoscope, so as to guide the operation. However, low-quality imaging and narrow field of view of the fetoscope increase the difficulty of the operation. Introducing an accurate placental vessel segmentation of fetoscopic images can assist the fetoscopic laser photocoagulation and help identify the abnormal vessels. This study proposes a method to solve the above problems. A novel encoder-decoder network with a dual-path structure is proposed to segment the placental vessels in fetoscopic images. In particular, we introduce a channel attention mechanism and a continuous convolution structure to obtain multi-scale features with their weights. Moreover, a switching connection is inserted between the corresponding blocks of the two paths to strengthen their relationship. According to the results of a set of blood vessel segmentation experiments conducted on a public fetoscopic image dataset, our method has achieved higher scores than the current mainstream segmentation methods, raising the dice similarity coefficient, intersection over union, and pixel accuracy by 5.80%, 8.39% and 0.62%, respectively.

  • 이 논문의 목적은 『단경』에 나타난 반야바라밀사상의 연원을 밝히는 데 있다. 남종선의 실천행인 ① 무념(無念)·무상(無相)·무주(無住) ② 일행삼매(一行三昧) ③ 좌선(坐禪) ④ 정혜일치(定慧一致)의 네 가지 모두 반야바라밀의 실천행으로 종합되기 때문이다. 무념(無念)·무상(無相)·무주(無住)의 행(行)은 말로 나타낼 수 없는 절대의 경지를 표현한 말로서, 이들이 바로 반야삼매이고 반야바라밀행이다. 일행삼매는 일상적인 모든 행위에서 항상 직심(直心)을 행하여 견성하는 것으로서, 견성의 내용을 반야바라밀의 실천으로 새롭게 전개한 것이다. 좌선(坐禪)은 반야바라밀의 실천에 의한 돈오견성을 주장한 것으로서, 불성사상과 반야사상을 새롭게 종합한 것이다. 정혜일체(定慧一體)는 자성의 본성 그 자체로서 체용(體用)의 이치를 두루 갖춘 견성(見性)의 뜻으로 통일되어 있다. 그런데 이러한 단경의 반야바라밀사상은 『반야경』·『유마경』·『열반경』 및 『대품반야경』에서 유래한 것이다. 그러므로 『단경』의 반야바라밀사상은 반야사상과 불성사상에 그 연원을 두고 있으며, 이들 사상은 『단경』에서 종합되어 선불교의 출발점이 되었고, 동시에 선불교의 사상으로 체계화되어 중국의 선종사상을 완성하게 되었다.

  • 오늘날의 소비자들은 가격, 제품의 품질 등 실용적 가치 보다 쇼핑의 즐거움, 라이프스타일의 구현, 매력적인 점포쇼핑환경, 브랜드 애착심 등의 정서적 가치를 더 중요하게 생각하고 있다. 이처럼 소비자들은 단순히 상품만을 구매하기보다는 다양한 가치를 얻기 위해 쇼핑을 한다는 사실은 여러 연구에서 제안되었다(안광호와 이하늘 2011; Mathwick 등 2001). 이렇듯 소매점포 선택과 관련한 소비자행동차원의 쇼핑경험가치와 브랜드자산에 대한 중요성과 관심이 높아지고 있지만 관련 연구는 미미한 실정이며 이와 관련한 비교문화적 연구는 매우 미비한 실정이다(황순호 2010). 본 연구는 한국과 중국의 소비자들의 소매점포 선택과 관련한 소비자행동연구의 필요에 의해 시작되었다. 또한 소비자행동분야에서 소비자 경험이 중시되면서 소매점내 쇼핑경험가치에 초점을 맞추었다. 본 연구는 정치, 경제, 사회, 문화적으로 서로 다른 한국과 중국의 소비자들을 대상으로 대형할인점 소매점포에서 고객들이 지각하는 쇼핑 경험가치와 브랜드자산과의 관계를 밝혀내고 이를 통해 점포 충성도와의 관계를 찾아내어 소매점의 쇼핑 경험가치와 관련된 시사점을 찾아내기 위한 국가 간 비교 연구를 시도하였다. 본 연구는 이론적 배경으로 쇼핑가치와 유통브랜드 자산, 그리고 점포 충성도에 대한 이론적 배경을 소개하였으며, 가설 검증을 위한 자료 수집을 위하여 한국과 중국의 대형할인점 고객들을 대상으로 한국과 중국의 대도시 (서울 과 북경) 소비자들을 표본프레임으로 설정하고, 대면 설문조사를 실시하였다. 연구의 결과 한중간 소비성향 차이 비교에 대한 결과를 요약하면 다음과 같다. 첫째, 한국소비자와 중국 소비자 간의 소비성향차이를 검정한 결과 중국 소비자들은 심미적 소비성향과 상징적 소비성향의 평균값이 한국 소비자들에 비해 높게 나타났으며 한국 소비자들은 쾌락적 소비성향이 중국소비자들에 비해 상대적으로 높은 것으로 나타났다. 둘째, 대형할인점에 대한 한국과 중국의 브랜드 자산 지각에 대한 연구결과 중국에 비해 한국 소비자들이 브랜드 인지와 브랜드 이미지를 모두 높게 지각하는 것으로 나타났다. 셋째, 한국과 중국에서 편의점과 할인점 이용 고객들이 지각하는 소매점에서의 쇼핑경험에 대한 탐색적 요인분석결과 각각의 국가에 따라 각기 다른 쇼핑경험가치가 나타났다. 한국의 할인점에서는 소비자이익 가치, 심미성가치, 유희성 가치가 중요한 쇼핑가치로 도출되었다. 또한 중국의 할인점에서는 유희성 가치, 심미성 가치, 소비자이익 가치, 서비스우수 가치가 중요한 쇼핑경험가치로 도출되었다. 이러한 연구의 목적에 대한 실증적 분석을 바탕으로 한국과 중국의 대형할인점 소비자들의 쇼핑경험가치과 브랜드자산을 바탕으로 한국의 대형할인점에 있어서 경험가치의 이론적 중요성에 관한 새로운 통찰력을 제공하여 주며 충성도 제고에 있어서 브랜드관리의 중요성에 대한 이론적 시사점을 제공하여 준다. 이와 더불어 유통의 국제화 시대에 있어서 대형할인점의 국제화에 요구되는 한국과 중국 간의 고객 가치의 차이점에 대한 비교문화적 관점에서 중요한 실무적 시사점을 제시한다. 즉, 해외유통전략을 실행하는데 있어서 쇼핑가치에 기반한 현지화 전략의 중요성에 대한 시사점을 제시하여 주며 국가차원에서의 차별적 유통전략의 개발 필요성을 제안하여 준다.
