The OTT service in Korea is not as popular as that in the U. S. This study argues that one of the major reasons of poor performance of OTT in Korea is that the OTT service providers did not acquire attracting contents, thus failing to appeal to Korean users. The other reason is Korean users are not willing to use OTT services because of high telecommunications fees to use OTT services. That is why most OTT users are using OTT services in WiFi zones, such as house, workplace, or school. This study investigated the popular OTT contents in recent three years, and how these popular OTT contents are provided in OTT service platforms, and how these contents are used in different places. The results of this study may provide several implications for OTT service providers' strategies in the future, and propose policy implications for the development of OTT services in Korea.

본 논문은 1996년 노동법 개정을 둘러싼 노동계의 총파업에 대해 보수적 성향을 갖는 조선일보와 진보적 성향을 갖고 있던 한겨레가 어떠한 방식으로 이러한 쟁점을 재현하고 해석하는 지를 분석했다. 당시의 노동계 총파업은 내부적으로는 민주화에 따른 시민사회의 성숙과 외부적으로는 글로벌라이제이션에 따른 국가 간 경쟁의 가속화라는 두 가지 정치경제학적 요인이 교차하는 공간에서 일어났으며, 동시에 광범위한 국민적 지지를 확보한 파업으로 그 상징적 의미를 갖고 있다. 이와 같이 주요 사회적 쟁점에 대한 두 신문간의 차이를 분석하기 위해 질적 분석 방법인 서사분석(Narrative Analysis)과 양적 분석 방법인 조응분석(Correspondence Analysis)을 사용했다. 서사분석은 사건의 발생과 진행 그리고 결말 과정에서 대립되는 행위자의 상징적 담론을 분석함으로써 사회적 쟁점에 대한 신문사간의 뉴스보도의 차이점 또는 유사성을 구분할 수 있으며, 조응분석은 주요 쟁점에 대해 행위자들이 어떠한 방식으로 서로 연계되는 지를 파악함으로써 역동적으로 총파업에 대한 행위자들의 관계의 변화를 공간적으로 탐색할 수 있는 장점을 갖고 있다. 서사분석 결과, 두 신문은 각각 서로 다른 서사구조를 기반으로 주요 행위자의 담론적 기호를 정반대로 구성하고 있었다. 사건 발생 단계에서는, 두 신문이 각각 국가 경쟁력 강화와 노동전 보호를 중심적인 서사구조로 설정해 차이를 보였으며, 대통령 및 여당과 민주노총이 대립적인 행위자로 설정되었다. 사건의 발전 단계에서는, 총파업의 불법성과 적법성 문제에 대한 갈등을 기본 서사구조로 제시한 채, 노동계를 포함한 시민사회와 정부기관이 대립적인 행위자로 등장했다. 사건의 갈등 해소 단계에서는 문제 해결을 위한 방법으로 두 신문이 대통령과 야당 지도자간의 정치적 해결과 노동법 통과에 대한 위헌론 제기를 중심으로 한 노동단체들의 지속적인 연대를 중심 서사구조로 각각 제시했다. 이 시기에서 주요 행위자들의 대립관계는 종료되었다. 조응분석 결과, 사건 발생과 위기 고조 단계, 그리고 갈등 해소 단계등 모든 시기에서 두 신문의 주요 행위자 구성에 있어서 차이가 나타났다. 다시 말해, 조선일보는 기본적으로 총파업을 둘러싼 문제의 구성과 발전, 해소 과정에서 정당이나 대통령, 야당 지도자 등과 같은 정치관련 행위자를 강조하고 있었다. 반면에, 한겨레는 대체로 로든 사건진행 단계에서 노동 관련 단체들과 시민단체의 역동적인 연대와 활동에 초점을 맞추고 있는 것으로 나타났다.

Health care has become one of the paramount issues of the 21st century as governments and individuals grapples the complex problems associated with contemporary medical care such as cost, affordability, and shifting demographic trends. The purpose of this study was to develop the critical success factors of medical tourism for health-care organizations and to measure the wights of these factors. For this purpose, we gathered the data from doctors, travelling agencies and scholars. about the success factors of medical tourism. Exploratory and confirmatory factor analysis was carried out to determine the factors as the Critical Success Factors of medical tourism. We did also the research to evaluate the validity and reliability of these factors. After that the Analytical Hierarchy Process (AHP) was applied to analyze the weight and significances among these factors. Factor analysis resulted in 15 major factors (Eigenvalue > 1.0). The AHP analysis showed the list of Critical Success Factors weighted by its significance priorities. The recommendable degree of reliability and validity suggests that these factors could be the valuable refences for the policy making process of the medical tourism in Korea.

In this study, habitat suitability was analyzed for three major honey tree species, namely Kalopanax septemlobus, Tilia amurensis, and Styrax obassis, in the Baekdudaegan Mountains using MaxEnt models. The AUC values indicating the prediction accuracies of the models were 0.747, 0.790, and 0.755 for K. septemlobus, T. amurensis, and S. obassis, respectively. The most important variables for K. septemlobus and T. amurensis were elevation, mean annual temperature, and slope, whereas mean annual temperature, elevation, and mean annual precipitation were the most important predictors for S. obassis. For all three studied species, elevation and mean annual temperature were the most important topographic and climatic factors, respectively, indicating that such variables are crucial for explaining species distribution. Honey tree species are essential resources in forest beekeeping, a high value-added process for improving forest income, and this study identified sites with the potential for management of such species in the Baekdudaegan Mountains, where it may be possible to establish a honey forest. However, the accuracy of the models should be improved through comprehensive analysis with abiotic variables, such as soil properties and aridity, which affect the distribution of honey tree species, as well as biotic variables, such as interspecific competition.

This study was carried out to investigate the seasonal and regional occurrence and development of major pest flies on the oyster mushroom. The survey was performed in the oyster mushroom houses located at 16 places, selected randomly throughout South Korea from July to August and from October to November in 1997. The six species of flies were found including three pest species from Sciaridae, Cecidomyiidae and Scatopsidae flies. The pattern of occurrence was somewhat dissimilar depending on the survey periods and regions. Among these, the most serious and abundant pest, Lycoriella mali (Diptera: Sciaridae), occurred year around at the regions surveyed. In this study, Coboldia fuscipes (Diptera: Scatopsidae) was confinned as a mushroom pest. Its larvae damaged the mycelium, and occurred usually in summer from July to August. The paedogenetic Mycophila sp. (Diptera: Cecidomyiidae) was found abundantly on the oyster mushroom bed, and caused a severe damage in fall from October to November.

Finding and selecting proper reviewers is a burden on the publisher of the journal. In order to solve this problem, the online submission system started to recommend appropriate reviewers automatically. It includes a variety of new features, from recommending authors in the references of submitted papers as reviewers to finding similar papers by searching the citation index and suggesting reviewer candidates extensively. This study investigated how the online submission system provides functions such as recommendation of reviewers. As a result of examining major online submission systems, ScholarOne and Editorial Manager were recommending reviewer candidates by commercial citation index and review history platform. On the other hand, JAMS, a domestic online submission system, did not have any advanced functions such as recommendation of candidates for reviewers. Sooner or later, in Korea, it seems that more efforts should be made to improve the function of online submission system, such as recommending suitable reviewers for papers.

This study was conducted to analyze the habitat suitability of the major honey trees including Kalopanax septemlobus Koidz., Prunus spp., Tilia spp., and Styrax obassia Siebold & Zucc. indigenous to mountain Gariwang and Yumeong using the machine learning approach (i.e., MaxEnt model). The AUC values of the model predictions were mostly above 0.7, and the results of the response curves showed that the environmental drivers that had effects on the habitat suitability of the major honey trees were elevation, mean annual precipitation, and mean annual temperature. These results indicate that climatic drivers along the elevation gradient are the main environmental drivers in explaining the distribution patterns of the major honey trees. In addition, the results of the response curves of Prunus spp. and Styrax obassia Siebold & Zucc. differed slightly in terms of slope and mean annual solar radiation as the main environmental drivers. The results of this study will be valuable for the establishment of honey tree forests and management plans for the natural and artificial forests in South Korea, as well as for the mapping the distribution of honey trees. Further studies at different regional levels, reflecting biotic drivers, will be needed to expand the production of honey and pollen at different strata and to produce honey annually.

지형학연구의 주요 쟁점의 하나는 한반도 산록에 분포하는 완만한 지형면 형성과 정에 관한 논의이다 한국 지형학계의 일각에서는 안정지괴에 속한 한반도에는 선상지발달이 불리하고 친식지형이 일반적이라는 편견이 있어, 산록완사면이 페디멘트로 이해되고 선상지 차체를 부인하는 경향이 있다. 또한 선상지와 하안단구, 해안단구 대부분이 페디멘트와 같은 과정을 거쳐 형성된 것으로 해석되면서 대학의 지형학 교재나 일부 교과서에 반영되어 혼란이 야기된다. (중략)

국내 농업인구 감소 대비 식품소비량이 증가함에 따라 농가의 인력을 대체하고 다양한 작업이 가능하며 가격이 저렴한 국내 기계화 기술이 필요하다. 무동력 디스크해로우 작업기는 경운과 배토가 가능한 복합작업기로서 작업기를 구성하는 주요 구성품들은 필드작업에 의해 발생되는 하중에 구조적 강도와 신뢰성이 충분히 확보되어야 한다. 또한, 실제로 필드 작업 시 작업기에 걸리는 하중은 복합하중 형태로 전달되기 때문에 단순한 형태 하중에 비해 하중계측에 어려운 점이 있으므로 하중계측점의 선정이 매우 중요하다. 본 논문에서는 하중계측점을 선정하기 위하여 복합기의 주요 구성품인 치즐(chisel) 및 디스크해로우암(disk harrow arm)에 대하여 구조해석을 수행하였으며, 3축 방향의 단위하중 응력 계산결과로부터 load reconstruction을 위한 스트레인 게이지 위치를 선정하였다. 또한, 스트레인 게이지의 신호가 하중해석에 적절한 값이 되도록 기존의 형상을 수정하였다.
