For 299 patients who had undergone cataract surgeries we investigated the difference in visual acuity and refractive power before and after cataract surgery and the clinical change of the visual acuity and the refractive power according to age, gender, hospital visit time and specific medical history. We found the factors affecting preoperative and postoperative outcomes of the cataract patients in metropolitan hospitals by input, process, and outcome and analyzed medical characteristics and patient characteristics as the input variables. T-test and ANOVA have been performed for statistical analysis of functional status, and general status and the technical characteristic as the process variable and the outcome variable of diagnosis. Visual acuity improved significantly in patients who had undergone cataract surgery. However, the change in refractive power did not show a statistically significant difference but only a slight difference. The improvement of male patients was greater than that of female patients. The difference in age was more effective in patients under 50 years old and the effect of cataract surgery was relatively high in patients without the presence of specific medical history. Cataract surgery did not seem to help all of the patients, but it is more effective in improving visual acuity and refractive power. We conclude that simultaneous cataract surgery in both eyes is reasonable in order to have at least the better effect.

In the circumstances of overflowing numbers of medical journals, progress of their own medical journal is one of the primary concerns of many medical societies. Among the 46-year-history of Journal of Korean Neurosurgical Society (JKNS), it undertook a period of important transition and preparation to take off for journal with international reputation during the period from 2001 to 2006. The overall process of manuscript handling, peer review, and editorial work has undergone systematic improvement. Workshops for authors, reviewer and editors were held, which were very helpful to improve the quality of submitted manuscript, peer review and editorial processing. Articles on the history, current status of the JKNS, citations and the change of proportion of types of articles were published, which provided insight about present condition and direction for further progress. It was changed into English journal in 2005. These efforts resulted in registration of the journal Chemical Abstract Service in 2005 and Science Citation Index Expanded in 2008 and SCOPUS in 2009. Now JKNS has become international journal, with about half of the submitted manuscripts from abroad, with increasing impact factor. Along with the effort of Korean Neurosurgical Society (KNS) members and support of KNS, dedication of Professor Dong Gyu Kim for the progress of JKNS is worth remembering, who served as Editor-in-Chief of JKNS during this period.

This study examines the history of Korean aviation industry and presents the investment strategy based on the evidence and the 4th industrial revolution. Looking at the evolution of the Korean aviation industry and its technological development will be a great help to support industrial and technological innovation in the future. The modern aviation industry is divided into stages of development, focusing on maintenance of equipment introduced in advanced countries, localization through license assembly, production of products based on technology, and international joint development. The development of aeronautics technology has been progressing towards a general improvement of economic efficiency, aircraft safety efficiency through environmental-friendliness, unmanned operation, and downsizing. The Korea Aerospace Research Institute has secured key technologies through development of several aircrafts such as Experimental Aircraft Kachi, EXPO Unmanned Airship, Twin-engine Composite Aircraft, Canard Aircraft, Multi-Purpose Stratosphere unmanned-airship, Medium Aerostats, Smart UAV, Surion, EAV-2H, KC-100, and OPV. The development strategy is discussed at the level of the evidence-based investment strategy that is currently being discussed, and so the investment priorities in aircraft is high. Current drone usage and development direction are not only producing parts using 3D printer, but also autonomous flight, communication (IoT, 5G), information processing (big data, machine learning). Therefore, the aviation industry is expected to lead the fourth industrial revolution.

The article assesses the functioning of the DE system or a separate educational institution, where it can be carried out on the basis of developed criteria or on a regulatory basis. The assessment was carried out on the basis of a qualitative and quantitative nature by comparing the actual state of affairs with a certain "ideal" (educational standard), which must be defined and used as a kind of benchmark against which the assessment is made. Conducted an assessment based on a regulatory framework that represents an alternative approach. It has been emphasized that the exceptional difficulty in determining the ideal indicators (norms) of the activities of universities, it has been found that the normative approach, in which the activities of traditional and open universities are compared, taking into account the differences in social, cultural and economic conditions, is the most acceptable.

Chinese traditional patterns, which are part of our national precious heritage, have a long history. Tiger culture plays a very important role in folk art. In modern society, it is a symbol of human spirit and morality. The tiger pattern is also a unique traditional pattern in Chinese folklore. From the Spring and Autumn period to modern society, the tiger pattern has evolved in form through thousands of years of development. It is also a representative intangible cultural heritage in contemporary times. It plays a special role in the cultural exchange of different regions, resulting in the generation of the creation of folk art with great local characteristics. Therefore, traditional tiger patterns are an important part of traditional Chinese folk culture and art. In this study, by analyzing the development and evolution history of Chinese traditional tiger patterns, the application methods of Chinese traditional tiger patterns were summarized, the rich cultural connotation, artistic characteristics and application of traditional tiger pattern in modern fashion design were discussed. In contemporary design, the new and improved tiger pattern styles were explored, intangible cultural heritage was interpreted and inherited, and the cultural and artistic values contained therein were extracted. The author combined with modern fashion design, according to people's aesthetic taste and design principles, it is recreated,so that the traditional pattern has certain characteristics of The Times.But at the same time it retains its original character,and the traditional tiger pattern was inherited and the cultural connotation of clothing design was enriched.

Zhang Yu was a famous Taoist priest and poet in Yuan Dynasty, compared with the identity of Taoist and poet, his handwriting had greater influence in history. According to the relevant historical data, people at that time were mainly attracted by his Taoist identity and poetic talent. However, if we considered him as a poet,or a calligrapher to inspect,it would be often easier than facing a Taoist priest. Zhang Yu's poems and relationships can be used as some clues for our investigation of his calligraphy activities,not only would it not affect us to judge the value of his calligraphy, but also we will comprehensively and objectively analyze his calligraphy works. His early calligraphy closely followed Zhao Mengfu, in his later years, when he met Yang Weizhen, the style of writing changed greatly.During this period, what kind of changes and fundamental influence had on Zhang Yu's life and book learning thoughts experienced. Our contributions to this paper are as follows.To solve this issue,this passage will try to find clues from several representative figures and representative calligraphy works of Zhang Yu, and draw on the research results of relevant scholars to discuss the identity of Zhang Yu as a Taoist priest and the origin and style characteristics of his handwriting and probed into the status and influence of his calligraphy in history.

This study analyzes the historical events that shaped South Korean Foreign Direct Investment (FDI) and its value to businesspeople. Chapter 2 reviews South Korean FDI literature, highlighting critical studies and a research gap. Chapter 3 strategically separates findings into four major historical events. Every event-from economic liberalization to technical advances-is studied. Chapter 5 offers valuable insights and guidance on how these events affect practitioners. The following chapters aim to promote FDI dynamics understanding and enable businesses and governments to make strategic decisions in South Korea's dynamic economy. Foreign Direct Investment (FDI) history in Korea is significant for practitioners. These events have impacted the nation's economy from the 1960s economic liberalization to modern technology advances. Practitioners must understand these events' far-reaching implications to make informed decisions. The opening up of the economy, chaebols' involvement, financial crises, and high-tech industry emphasis provide excellent lessons. This understanding helps practitioners navigate the global economy, adapt, and be resilient for sustainable economic growth in the Republic of Korea. Thus, practitioners should actively advocate for FDI and economic growth policies with government agencies. Collaboration ensures that the government's strategic vision matches industry practitioners' requirements and goals. By working together, practitioners help create policies that make Korea more appealing to international investors.

This introduction is both a statement of a research problem and an account of the first research results for its solution. As more historical databases come online and overlap in coverage, we need to discuss the two main issues that prevent 'big' results from emerging so far. Firstly, historical data are seen by computer science people as unstructured, that is, historical records cannot be easily decomposed into unambiguous fields, like in population (birth and death records) and taxation data. Secondly, machine-learning tools developed for structured data cannot be applied as they are for historical research. We propose a complex network, narrative-driven approach to mining historical databases. In such a time-integrated network obtained by overlaying records from historical databases, the nodes are actors, while thelinks are actions. In the case study that we present (the world as seen from Venice, 1205-1533), the actors are governments, while the actions are limited to war, trade, and treaty to keep the case study tractable. We then identify key periods, key events, and hence key actors, key locations through a time-resolved examination of the actions. This tool allows historians to deal with historical data issues (e.g., source provenance identification, event validation, trade-conflict-diplomacy relationships, etc.). On a higher level, this automatic extraction of key narratives from a historical database allows historians to formulate hypotheses on the courses of history, and also allow them to test these hypotheses in other actions or in additional data sets. Our vision is that this narrative-driven analysis of historical data can lead to the development of multiple scale agent-based models, which can be simulated on a computer to generate ensembles of counterfactual histories that would deepen our understanding of how our actual history developed the way it did. The generation of such narratives, automatically and in a scalable way, will revolutionize the practice of history as a discipline, because historical knowledge, that is the treasure of human experiences (i.e. the heritage of the world), will become what might be inherited by machine learning algorithms and used in smart cities to highlight and explain present ties and illustrate potential future scenarios and visionarios.

The history of the Korean lighthouse have been known to be begun from which installed by the purpose of the Japanese invasion of the outside. Modern navigational aid system have configured during the Japanese ruling era since the Incheon Palmido Lighthouse was built in 1903 as the first lighthouse in Korea. But in this regard it needs to be considered more carefully. Busan, as the city of international port and of Choryang Waegwan, had been a center of foreign relations between Korea and Japan since early 15th century. Because that reason, International port facility has been developed for a long time ago in Busan for example lighthouse, breakwater, wharf, jetty and so on. Nevertheless the lack of historical data and basic research related to the marine caused the proper history could not be established until now. In recently the basic translation of Korean Maritime Customs documents started to finish, and a compilation book of old pictorial maps on Choryang Waegwan was issued. As a result, more objective history of Busan Aids to Navigation can be investigated.
