Due to the increasing demand and importance of non-face-to-face education, open online learning platforms are getting interests both domestically and internationally. These platforms exhibit different characteristics from online courses by universities and other educational institutions. In particular, students engaged in these platforms can receive more learner autonomy, and the development of tools to assist learning is required. From the past, researchers have attempted to utilize process mining to understand realistic study behaviors and derive learning patterns. However, it has a deficiency to employ it to the open online learning platforms. Moreover, existing research has primarily focused on the process model perspective, including process model discovery, but lacks a method for the process pattern and instance perspectives. In this study, we propose a method to identify learning patterns within an open online learning platform using process mining techniques. To achieve this, we suggest three different viewpoints, e.g., model-level, variant-level, and instance-level, to comprehend the learning patterns, and various techniques are employed, such as process discovery, conformance checking, autoencoder-based clustering, and predictive approaches. To validate this method, we collected a learning log of machine learning-related courses on a domestic open education platform. The results unveiled a spaghetti-like process model that can be differentiated into a standard learning pattern and three abnormal patterns. Furthermore, as a result of deriving a pattern classification model, our model achieved a high accuracy of 0.86 when predicting the pattern of instances based on the initial 30% of the entire flow. This study contributes to systematically analyze learners' patterns using process mining.

Recently, there has been growing social interest in the use of care farms as part of therapy for neurological or mental patients and regional innovation for rural areas. Care farm, which combines the health treatment and rural innovation perspectives, is important to establish a proper governance system for mutual collaboration with various stakeholders. However, there is still a lack of research on this. Therefore, this study designed the care farm governance framework and comparatively analyzed the governance between Netherlands paradise care farm and Belgium blue farm, which are major successful care farm cases. The results showed different governance system between Netherlands and Belgium care farm in terms of institutional and financial support, regional characteristics, structure, operation, and strategy. In Netherlands, as the central government-initiated therapy-centric, care farm governance is concentrated in treatment of patient mainly supported by Ministry of Health, Welfare and Sports under the law on social support. Whereas, in Belgium, as local government-initiated agriculture-centric, care farm governance is mainly focused to lead voluntary participation of agricultural cooperatives and medical institutions in regional area. This study provides a theoretical foundation of governance type and system for the care farm research and suggests guidelines of care farm governance for the governments like South Korea consider activating care farm.

The purpose of this study is to investigate patient satisfaction for the spacial environment of the rehabilitative facilities, and by this to examine areas of patients' needs to develop patient-friendly improvement in spacial environment. 308 patients were surveyed at physical therapy centers of 6 hospitals or rehabilitative institutions in Daejeon with patient satisfaction questionnaire. The spatial environment satisfaction was categorized into 7 constructs and the data were statistically analyzed and compared by t-test and ANOVA according to the patient characteristics. As a result, inter-floor transfer was found to be the area with the least satisfaction, especially in the in-patient group. Locating floor level was the second lowest satisfied construct. Comfort was relatively highly satisfied construct overall, but patients with neurological disease had less satisfaction than with musculoskeletal disease. Patients in 20's were less satisfied in wayfinding than 60's. Satisfaction for interior design was lower in subject in 50's than 70's. These findings can be used as evidences to improve spacial environment design for rehabilitative facilities to the better patient satisfaction.

The Korean government is actively pursuing an ambitious IT strategy to establish Korea as one of the leaders in the world IT market. To implement the strategy, successful technology transfer from research institutions to market should be achieved. Comprehensive literature identifies sixteen variables affecting the process and results of technology transfer. The research results in four key factors in technology transfer: Communication, Distance, Equivocality, and Motivation. Communication refers to the degree to which a medium is able to efficiently and accurately conveys task-relevant information and media while distance involves both physical and cultural proximity. Equivocality refers to the degree of concreteness of technology to be transferred while motivation involves incentives for and the recognition of the importance of technology transfer activities. Further analysis shows that there are four distinctive clusters and they show very contrasting characteristics in terms of four key factors. The careful mapping of the four clusters on the four key factors show very informative technology transfer patterns, the Technology Transfer Grid.

This paper introduces Database security to prevent the rapidly increasing issue of private information leakage. The Database security examined in the paper separates into DB access control area and DB encryption area which further leads the paper to analyze the factors of the two areas and suggest necessary elements for creating stable Database security. In addition, the paper examines previous DB security programs by areas and analyzes pros and cons from the tested result. The experiment indicated that while DB access control presents less degradation and reduced the need to modify the existing DBMS since the access control operates at the end point of the network, DB encryption presented strength in protecting the data from unauthorized access. On the other hand, DB access control is less useful in preventing the attack in advance which leaves the log to enable tracking afterward while DB encryption can only be operated by limited types of Database and causes degradation due to system load and shows higher percentage of failure when creating the system. This paper examines characteristics of Database security areas in order to be used as a reference for institutions or companies seeking stable Database security.

The purpose of the study was to analyze the apologies made in Korea for the past 10 years, and to diagnose how Koreans used crisis communication strategies. For the analysis, typology of crisis communication strategy was adopted from previous study as well as the new typology distinctively found in Korea. Also preferred crisis communication strategies were analyzed by crisis subject, by crisis type and by stage of crisis. Results showed that among the crisis communication strategies, apology and corrective action were the most used strategies, followed by bolstering and appealing to sympathy. Preferred crisis communication also differed by crisis subject, by crisis type and by stage of crisis. When the crisis subject were government or public institutions, when the locus of crisis responsibility was internal, and when the crisis was a controllable human/social crisis, the justification strategy was preferred. The results seemed to be related to the unique cultural characteristics of Koreans, especially to sense of Cheong and Chemyon. Indirect corrective action and transcendence were Chemyon-saving strategies while bolstering and appealing to sympathy were strategies appealing to Cheong. Future study should address the new typology of crisis communication strategy reflecting the cultural characteristic.
