Drawing on an open system approach to understanding schools as organizations, this study examined whether challenges experienced by teachers in immigrant neighborhoods are mitigated to the extent in which schools effectively collaborate with parents and other agents in the neighborhoods. Data were gathered from a total of 328 teachers in 32 elementary and middle schools located within areas characterized by high levels of immigrant residential concentration in Seoul and Gyeonggi. The data showed that challenges experienced by teachers were significantly lessened in schools that had organic ties with agents in the external environments. This finding sheds new light on the importance of understanding schools as open-system organizations whose successful performance largely depends on factors external to classrooms. It appears that boundary spanning and bridging strategies may be utilized by school leaders to improve teachers' task performance at schools in areas of immigrant concentration.

As issues of education, employment and so on, the medical issue is one of the hot spots of society in China today. The health system reform which was pushed ahead after China's Revolution and open to the outside world hasn't received great progress. Many actual problems haven't been solved, for example it is difficult and expensive to see a doctor. With the development of the economy and society, the citizen's legal consciousness has gradually risen. They make a claim for better medical service. At the same time, the number of the disputes of medical care arises annually. China has sped up the opening of service trade for fulfilling promises of entry the WTO since 2001. China has already opened many service trade fields, including medical field. From the domestic perspective, there are many problems in domestic medical department. From the international perspective, China's present medical level falls behind the world advanced medical level. Under this background, it is a bold act for China to open the medical service field to foreign investors. Today, a huge medical service market is developed in China. However, the government's investment to medical devices and the financing channels is limited. Therefore, it is inevitable that individuals, social organizations and foreign investors invest to the medical market. In view of the situation, Chinese government issued a series of relevant laws and rules. In recent years, many multinational companies, consortiums, charitable institutions, enterprises and individuals establish various medical institutions in China. But there are rare research in the actuality and legal subject of foreign investment to Chinese medical market. Hence, it is necessary to realize the actuality of foreign investment to Chinese medical market, to familiar with the elements and procedure of establishing foreign joint and cooperative medical institution. Meanwhile, analyzing the existing problems and posing the legal subject have important theoretic and practical value.

The purpose of this study is to discuss Joseon dynastyis first perspective on the Western-style Court Costume which was newly introduced to Joseon through the problems receiving the credential that Japan had sent in new style. For this study, the records of Joseon and Japan at that period have been analyzed. The followings are the results of this research; First, a critical argument on the Western-style Court Costume occurred just before the Port Opening because whether wearing a western costume was the key factor in Joseon dynastyis receiving the credential that Japan had send in new style. Second, Japan received western costume as its domestic courtesy system by establishing the Court Costume of Civil servants in 1872 and consequently Japan established new ceremony procedure of western-style bow in 1875. Third, Joseon dynasty officially opposed to the Western-style Court Costume when Japan sent the credential, because the western costume selected by Japan had beenregarded as that of western barbarian at that time in Joseon. Accordingly, it seems reasonable that before the introduction of western costume into Joseon dynasty, an open-door policy for the West had been a prior settlement for Joseon dynasty regardless of the details of Western-style Court Costume. And also, the pride of civilization of Joseon dynasty, which has been used to express Joseon dynastyis identity as Joseon-centrism, had to be converted before the open-door policy. Ultimately, it could be inferred that the reception of the Western-style Court Costume had been raised as the political and diplomatic problems in the circumstances when the submissive relationship in the traditional Eastern- Asia had been forced to be converted to modern sovereign international relationship.

Measuring Information Technology(IT) organizations' activities have been limited to mainly measure financial indicators for a long time. However, according to the multifarious functions of Information System, a number of researches have been done for the new trends on measurement methodologies that come with financial measurement as well as new measurement methods. Especially, the researches on IT Balanced Scorecard(BSC), concept from BSC measuring IT activities have been done as well in recent years. BSC provides more advantages than only integration of non-financial measures in a performance measurement system. The core of BSC rests on the cause-and-effect relationships between measures to allow prediction of value chain performance measures to allow prediction of value chain performance measures, communication, and realization of the corporate strategy and incentive controlled actions. More recently, BSC proponents have focused on the need to tie measures together into a causal chain of performance, and to test the validity of these hypothesized effects to guide the development of strategy. Kaplan and Norton[2001] argue that one of the primary benefits of the balanced scorecard is its use in gauging the success of strategy. Norreklit[2000] insist that the cause-and-effect chain is central to the balanced scorecard. The cause-and-effect chain is also central to the IT BSC. However, prior researches on relationship between information system and enterprise strategies as well as connection between various IT performance measurement indicators are not so much studied. Ittner et al.[2003] report that 77% of all surveyed companies with an implemented BSC place no or only little interest on soundly modeled cause-and-effect relationships despite of the importance of cause-and-effect chains as an integral part of BSC. This shortcoming can be explained with one theoretical and one practical reason[Blumenberg and Hinz, 2006]. From a theoretical point of view, causalities within the BSC method and their application are only vaguely described by Kaplan and Norton. From a practical consideration, modeling corporate causalities is a complex task due to tedious data acquisition and following reliability maintenance. However, cause-and effect relationships are an essential part of BSCs because they differentiate performance measurement systems like BSCs from simple key performance indicator(KPI) lists. KPI lists present an ad-hoc collection of measures to managers but do not allow for a comprehensive view on corporate performance. Instead, performance measurement system like BSCs tries to model the relationships of the underlying value chain in cause-and-effect relationships. Therefore, to overcome the deficiencies of causal modeling in IT BSC, sound and robust causal modeling approaches are required in theory as well as in practice for offering a solution. The propose of this study is to suggest critical success factors(CSFs) and KPIs for measuring performance for IT organizations and empirically validate the casual relationships between those CSFs. For this purpose, we define four perspectives of BSC for IT organizations according to Van Grembergen's study[2000] as follows. The Future Orientation perspective represents the human and technology resources needed by IT to deliver its services. The Operational Excellence perspective represents the IT processes employed to develop and deliver the applications. The User Orientation perspective represents the user evaluation of IT. The Business Contribution perspective captures the business value of the IT investments. Each of these perspectives has to be translated into corresponding metrics and measures that assess the current situations. This study suggests 12 CSFs for IT BSC based on the previous IT BSC's studies and COBIT 4.1. These CSFs consist of 51 KPIs. We defines the cause-and-effect relationships among BSC CSFs for IT Organizations as follows. The Future Orientation perspective will have positive effects on the Operational Excellence perspective. Then the Operational Excellence perspective will have positive effects on the User Orientation perspective. Finally, the User Orientation perspective will have positive effects on the Business Contribution perspective. This research tests the validity of these hypothesized casual effects and the sub-hypothesized causal relationships. For the purpose, we used the Partial Least Squares approach to Structural Equation Modeling(or PLS Path Modeling) for analyzing multiple IT BSC CSFs. The PLS path modeling has special abilities that make it more appropriate than other techniques, such as multiple regression and LISREL, when analyzing small sample sizes. Recently the use of PLS path modeling has been gaining interests and use among IS researchers in recent years because of its ability to model latent constructs under conditions of nonormality and with small to medium sample sizes(Chin et al., 2003). The empirical results of our study using PLS path modeling show that the casual effects in IT BSC significantly exist partially in our hypotheses.

Open Data Cube(ODC) has been emerging and developing as the open source platform in the Committee on Earth Observation Satellites(CEOS) for the Global Earth Observation System of Systems(GEOSS) deployed by the Group on Earth Observations (GEO), ODC can be applied to the deployment of scalable and large amounts of free and open satellite images in a cloud computing environment, and ODC-based country or regional application services have been provided for public users on the high performance. This study first summarizes the status of ODC, and then presents concepts and some considering points for linking this platform with Korea Multi-Purpose Satellite (KOMPSAT) images. For the reference, the main contents of ODC with the Google Earth Engine(GEE) were compared. Application procedures of KOMPSAT satellite image to implement ODC service were explained, and an intermediate process related to data ingestion using actual data was demonstrated. As well, it suggested some practical schemes to utilize KOMPSAT satellite images for the ODC application service from the perspective of open data licensing. Policy and technical products for KOMPSAT images to ODC are expected to provide important references for GEOSS in GEO to apply new satellite images of other countries and organizations in the future.

The purpose of this study is to analyze the needs of teachers as main users to make suggestions for active use of educational information sharing system. The study sets three research tasks about the problems of the current system, improvements, and desired content from the perspective of teachers. To collect specific opinions, we conducted an open questionnaire survey and made a qualitative analysis using the NVivo 10 program. The present system has such problems as functional issues, lack of data reliability, systemic problems for sharing and use. We suggest that in order to enhance Web site services, authoring tools for editing contents and new search engines with customized search function need to be provided. In addition, the open market service system has to be established, so that teachers can actively create, share, and distribute to meet the various needs of teachers. Finally, to promote free access to the system, copyright issues need to be resolved to prevent the potential digital piracy.

While there are increasing requests for open innovation, prior studies have focused mainly on the utilizing the external sources. This study suggests to broaden the way of measuring openness to include the innovation management factors and output besides of utilizing the external sources. Additionally, the new measures will compare the status of openness in small and medium enterprises between Korea and Japan. There is greater differences in openness between SMEs and big firms in Japan than ones in Korea. Although SMEs in Japan utilize the external knowledge sources more actively than ones in Korea, they show less openness from the perspective of managerial factors such as metric for open innovation, collaboration system, investment for collaboration, and performance.

Recently, Golang has been gaining attention in programming language rankings each year due to its cross-compilation capabilities and high code productivity. However, malware developers have also been increasingly using it to distribute malware such as ransomware and backdoors. Interestingly, Golang, being an open-source language, frequently changes the important values and configuration order of a crucial structure called Pclntab, which includes essential values for recovering deleted symbols whenever a new version is released. While frequent structural changes may not be an issue from a developer's perspective aiming for better code readability and productivity, it poses challenges in cybersecurity, as new versions with modified structures can be exploited in malware development. Therefore, this paper proposes GoAsap, a detection and analysis system for Golang executables targeting the new versions, and validates the performance of the proposed system by comparing and evaluating it against six existing binary analysis tools.

A factorization-based 3D reconstruction system is realized to recover 3D scene from an image sequence. The image sequence is captured from uncalibrated perspective camera from several views. Many matched feature points over all images are obtained by feature tracking method. Then, these data are supplied to the 3D reconstruction module to obtain the projective reconstruction. Projective reconstruction is converted to Euclidean reconstruction by enforcing several metric constraints. After many triangular meshes are obtained, realistic reconstruction of 3D models are finished by texture mapping. The developed system is implemented in C++, and Qt library is used to implement the system user interface. OpenGL graphics library is used to realize the texture mapping routine and the model visualization program. Experimental results using synthetic and real image data are included to demonstrate the effectiveness of the developed system.
