Picture archiving and communication system (PACS) is an image information technology system for the transmission and storage of medical images. In Korea the first full PACS was installed at Samsung Medical Center in 1994, but, the rate of distribution was very slow. The government's approval for the medical insurance reimbursement for full PACS examinations in November 1999 became the turning point. Thereafter the number of hospitals with full PACS has steeply increased. In September of this year, PACS was installed at 906 medical institutes, including most of university hospitals and general hospitals. The first full dental PACS was installed at Wonkwang University Dental Hospital in 2002. Now ten out of eleven university dental hospitals implemented full dental PACS. The current status and technological factors of dental PACS in Korean university dental hospitals and the future perspectives of dental PACS are described.

In this paper, we examine the shortening of the theatrical window whereby films play at theaters for 90 days as one of the most portentous issues that could reshape the Hollywood film industry. We first examine the windows system that protected the status of movie theaters and the studios' attempt to shorten the theatrical release to create a premium VOD window in response to the declining revenue of DVDs after 2007 and the rise of streaming services. We then look at some of the major disruptions in distribution COVID-19 brought about. We also explore the shortening of the theatrical release in the wake of the pandemic and shows the changes in the theatrical release, along with the expansion of streaming services, raise questions over the long-held primacy of the theatrical release and the definition of film with the theatrical release as its part. From this, we highlight Hollywood at the crossroads of major changes with its future less certain than ever before.

2012년 1월부터 공간정보 오픈플랫폼의 서비스가 시작된 이래로, 서비스가 늘어남에 따라 서비스 이용자 수와 시스템의 규모가 크게 증가하게 되었다. 그러나 이러한 오픈플랫폼 시스템이 가지고 있는 하드웨어 자원들이 어느 수준의 서비스를 처리할 수 있는지에 대한 자세한 분석 결과는 전혀 알 수 없었다. 이러한 이유로 특정 이슈와 더불어 서비스 이용자가 급증할 때마다 서비스를 처리하기 위하여 단순히 하드웨어 증설을 통해 일시적으로 서비스 지연 문제를 해결하여 왔다. 이에 본 연구에서는 현재 오픈플랫폼이 보유하고 있는 시스템 성능을 정확히 파악하여 향후 동일한 문제가 발생하지 않도록 근본적인 해결책을 제시하고자 한다. 구체적으로 본 연구에서는 NMON을 이용한 하드웨어 성능 분석과 nGrinder를 이용한 웹서비스 부하 테스트를 통해 오픈플랫폼이 현재 가지고 있는 정확한 시스템 성능을 파악하고, 이후 보다 나은 서비스를 제공할 수 있는 시스템으로 개선하기 위한 자원 재조정 방안을 제시하고자 한다.

본 연구는 프랜차이즈 시스템에 참여하는 본부와 가맹점 관계를 브랜드 중심으로 관계해지 및 구조적인 관련성에 대해서 설명하고자 하였다. 즉, 프랜차이즈 시스템에 있어서 브랜드 자산, 내부브랜드 활동, 갈등과 관계해지 간에 어떠한 관련성이 있는 지를 브랜드를 중심으로 연구하였다. 연구방법은 브랜드를 외생적 요인과 내생적 요인으로 구분하여 탐색적 연구를 진행하였다. 실증대상은 국내 프랜차이즈 시스템에 참여하고 있는 가맹점이다. 연구결과, 브랜드의 외생적 요인인 거래특유 투자와 브랜드 자산, 브랜드 커뮤니케이션은 브랜드의 내생적 요인인 브랜드 내재화와 갈등에 영향을 미쳤으며, 관계해지에도 영향을 주는 것으로 나타났다. 또한 브랜드의 내생적 요인은 관계해지에 영향을 주는 것으로 나타났다. 이를 통해 본 연구는 프랜차이즈 시스템의 지속적인 관계유지를 위해 브랜드의 역할에 대한 이론적, 관리적 시사점을 도출하였다.

이 논문은 한국 독립영화의 대중성 모색에 있어서 효율적 소통에 의한 한국 독립영화의 나아갈 길을 고찰함으로써 현재 한국 독립영화 문제점을 짚어보고 모색하는데 있다. 이를 위해서 독립영화란 무엇이며, 독립영화의 모호한 경계를 살펴본 후, 한국 독립영화의 현실과 문제점 그리고 제작, 배급에 있어서 효율적 소통을 위한 과제는 무엇인지 논의하였다. 독립영화 범위는 해석, 인식의 차이에 따라 독립영화의 범위가 결정되며, 관객과 쌍방향 소통의 중요성이 제기되므로 효율적 소통에 있어서 독립영화의 흥행작품들을 통해 분석해본다. 효율성 중심에 의해 해석되어지는 제작효율성은 적은 제작비와 지원 금액으로 완성하는 것이며, 배급효율성이란 많은 상영기회를 잡고, 많은 수익을 남기는 것과 영화제 상영 및 가치평가가 높다고 볼 수 있다. 독립영화인의 노력, 독립영화인과 관객의 쌍방향소통 정도 그리고 정책부문 정도에 의해 효율적 제작, 배급이 이루어 질 것으로 본다. 이런 가능성에 의해 한국 독립영화의 미래는 밝을 것이다.

Purpose: North Korea is a very close country geographically and culturally, but the nation has been one of the most secretive countries in the world. However, in recent years, North Korean society has been known to rapidly change its economic environment as well as its diplomatic and political environment. Since the gaining power of Jong-un, Kim in 2012, the North Korean government has implemented a new set of economic policies. North Korea has embraced limited market systems and mechanisms that have become a part of the formal planned economy. This study is concerned with the recent changes in the market and marketing activities of the communist country. It also seeks to gain an understanding of the changing market behavior of North Korean consumers. The purpose of this study is to enhance understanding of the market environments of North Korea and to provide appropriate implications for practitioners and researchers. Research design, data and methodology: Academic access to information that can understand North Korea's reality is minimal. Therefore, this study was conducted based on a qualitative analysis of secondary data. The existing literature on North Korea, related news and reports were the basis of the analysis. Analysis of secondary data related to North Korea was the main methodology of the study. Results: The official ideology of North Korea rejected most aspects of marketing, and yet there were marketing activities in North Korea. This article focuses on the development of market and marketing activities in North Korea during the recent years. This study indirectly confirmed that the market function is being activated in North Korea, and the basic functions of marketing such as advertisement, price, and distribution are being formed. In this process, the activation of the 'Jangmadang(market)' played a significant role. Conclusions: Research shows that North Korea is rapidly developing its own market function. In addition, marketing activities such as advertising and pricing strategies seem to be unprecedentedly active. However, due to changes in the political environment, the future development of North Korea's marketing is still in flux. Efforts to improve mutual understanding through continuous research are required.

Water is a limited source that needs to be properly managed and distributed to the ever-growing population of the world. Rapid urbanization and development have increased the overall water demand of the world drastically. However, there is loss of billions of liters of water every year due to leakages in water distribution systems. Such water loss means significant financial loss for the utilities as well. World bank estimates a loss of $14 billion annually from wasted water. To address these issues and for the development of efficient and reliable leakage management techniques, high efforts have been made by the researchers and engineers. Over the past decade, various techniques and technologies have been developed for leakage management and leak detection. These include ideas such as pressure management in water distribution networks, use of Advanced Metering Infrastructure, use of machine learning algorithms, etc. For leakage detection, techniques such as acoustic technique, and in recent yeats transient test-based techniques have become popular. Smart Water Grid uses two-way real time network monitoring by utilizing sensors and devices in the water distribution system. Hence, valuable real time data of the water distribution network can be collected. Best results and outcomes may be produced by proper utilization of the collected data in unison with advanced detection and management techniques. Long term reduction in Non Revenue Water can be achieved by detecting, localizing and repairing leakages as quickly and as efficiently as possible. However, there are still numerous challenges to be met and future research works to be conducted in this field.

This study was a methodological research to develop computerized patient classification system. The subjects of this investigation were 435 inpatients except redundant data and outliers in P University Hospital from January 18, 2000 to January 24, 2000. The data was analyzed by discrimination analysis and adopted discriminant variables were 1) sum of frequency for the nursing activities, 2) the number of nursing activities that do not need to consider intensity of the activities, and 3) total hours of nursing activities that need to consider their intensities. Discriminant function developed by this study classified the patients into 4 groups; class I, 251 ; class II, 125 ; class III, 39 ; class IV, 20. The Hit ratio was 89.23. Based on this study, following suggestions can be made for the future research 1. Inclusive patient classification system, which includes more expanded direct nursing care factors, need to be developed and examined. 2. This developed classification system can be utilized to evaluate patient distribution and to estimate adequate numbers of nursing staffs in each nursing unit.
