This research focuses on rural interpreter's behaviors and needs in rural tourism village around country. Although it happens that many farm tourism guides are accomplished in rural tourism village, but significant interest on this topic has not been identified yet. Therefore the primary objective of this study lies in identifying rural interpreter's behaviors and needs who is active play in rural tourism village. The study was conducted in a small rural community where tourism is still at its emerging stage. It was found that rural interpreter played active role by studying about rural culture and farm interpret for himself. But they was pointed out multifarious activities with various rural experience guide, and they used reality in the process of the interpret, but not village history. farm tourism guides demanded their expertise or special ability.

Recently our society confronts with the concern over the college students' apparent lack of understanding and interesting of mathematics. In late 1980s the calculus reform movement in US was triggered to increase both passing rates and a general interest in the subject. The purpose of this paper is to investigate teaching of college calculus and its curriculum in order to promote students' interesting and understanding. We deal with 4 questions. Firstly, we research the history and motivation of the calculus reform movement in US. Secondly, we do case study about the debate between reformed and traditional calculus. Then we evaluate the effectiveness of reformed calculus in comparison to traditional calculus. Finally we investigate possible ways to apply reformed calculus in our university mathematics education and suggest some points to improve teaching calculus.

At present Internet, a huge network connecting many computers in the world, has become a major boom to business. It seems to change not only telecommunications, but also changes the business world. It was utilized by a maximum of about 1,000,000 at the end of the 1980's. This figure has increased dramatically to approximately 40,000,000 at present. This enormous increase has been from two reasons. One is that an open door for businesses begun in 1990. This fact called to account a new interest of many enterprises looking to expand their business through Internet. Prior to that Internet was confined to academic utilization and not used for business purposes. The other reson is that a method was developed where desired information could be easily searched. This article describes the fundamentals of Internet so that one should know the history of Internet and the connection method to use it in practice in Korea. The splendor of Internet cannot be understood until it is tested In practice. The readers are strongly urged to participate in the Internet.

Graphene is a two-dimensional sp2 layer material. Despite the short history in the empirical synthesis of the graphene layers, the academic/industrial unique features have brought highly significant interest in research and development related to graphene-related materials. In particular, the electrical and optical performances have been targeted towards pre-existing microelectronicand emerging nanoelectronic applications. The graphene synthesis relies on a variety of processing factors, such as temperature, pressure, and gas ratios involving H2, CH4, and Ar, in addition to the inherent selection of copper substrates. The current work places its emphasis on the role of experimental factors in growing graphene thin films. The thermally-grown graphene layers are characterized using physical/chemical analyses, i.e., four point resistance measurements, Raman spectroscopy, and UV-Visible spectrophotometry. Ultimately, an optimization strategy is proposed in growing high-quality graphene layers well-controlled through empirical factors.

The study on Electrostatics represents the first scientific interest of human being on electrical phenomena, and it led to enormous progress of electrical and electronic science and engineering up to the current levels. Electrostatics, however, has been long forgotten in the stream of this history as a tribial minor field. Interesting enough, this minor sector has regained recently its new life, in particular in the area of high-technologies, and Electrostatics is going to become one of the most important field in the future of electrical and electronics engineerings. It is impossible to cover the entire trend of this emerging field in a limited space, so that spot lights shall be focused on several important topics in this paper.

In 2021, Tokyo held the delayed 2020 Olympics in the ongoing COVID-19 pandemic. As with any Olympics, the final medal count was of particular interest. Since 2004, South Korea has consistently ranked in the top ten most successful countries for four straight Summer Olympics. However, in 2021, it fell short of a top ten finish for the first time since 2004. There may be many factors that affect the final medal count in any Olympics, and this study compares and looks for correlations between some of these factors including final medal count, GDP, population, size of Olympic contingent, and Freedom Index. The study pays particular attention to South Korea and other countries which have seen a dramatic change in Freedom Index score since 1972, when the index was first published.

Bronchoscopy has evolved over the past few decades and has been used by respiratory physicians to diagnose various airway and lung diseases. With the popularization of medical check-ups and growing interest in health, early diagnosis of lung diseases is essential. With the development of endobronchial ultrasound, ultrathin bronchoscopy, and electromagnetic navigational bronchoscopy, bronchoscopy has been able to widen its scope in diagnosing pulmonary diseases. In this review, we have described the brief history, role, and complications of bronchoscopy used in diagnosing pulmonary lesions, from simple flexible bronchoscopy to bronchoscopy combined with several up-to-date technologies.

The purpose of this study was to review the studies related to the problem of context in science education. Firstly, studies on context and context effects in science education (and also those related in cognitive psychology) were summarized according to the topics concerning science learning, such as deductive reasoning and probabilistic judgement, controlling variables, scientific inquiry skills, memory and consistency of misconceptions, selecting cognitive strategies and problem solving, achievement and momentum effect, and interest, religion and culture. Secondly, the common problems appeared from the analysis of the studies were discussed, such as (1) how to define contexts?, (2) how to classify contexts?, (3) how to characterize the effects of contexts? and (4) how to explain the context effects? Finally, the implications of the analysis of the studies on the problem of context were discussed in terms of recent development of science education, such as misconception studies, STS science education and the application of the history of science to science teaching.

In Korea, there still exist a number of modern architectural structures which were built from 1876 - when Korea first opened its port to foreign trade - to the early 1960s. Modern architectures have been rather neglected from the study of Korean architecture history partly because of its short period and negative attitude toward them that they are remains of the Japanese colonial period. However, interest in modern structures is recently increasing, and researches and studies are actively going on. This dissertation is a study on brick laying techniques and design characteristics of Modern brick structure churches in Jeonbuk-province. The results demonstrate that modern brick structure churches in Jeonbuk-province have become small and simple with time and that their structures and designs are closely related.

In political science there is broad interest in whether a newly established democracy succeeds in overcoming the perils of democratisation and matures into a consolidated democracy or regresses to authoritarianism. Taiwan was under martial law for almost four decades. Democratic consolidation, therefore, is primarily a question of how to overcome the legacies of the former authoritarian regime. Nationalism and dysfunctional political institutions are some of the legacies that limit Taiwan's democratic development. The study of these destructive elements is important in the attempt to interpret Taiwan's most recent political history and to formulate effective democracy-building policies. In the following, I would like to address the aforementioned legacies and their implications for Taiwan's current and future democratic development.
