The purpose of this study is to reveal the Korean learners' usage pattern of '의', the genitive particle, according to semantic classification, so that it can be referred to in determining the contents and methods of related education. The method of this study adopts a quantitative analysis using learners corpus established by National Institute of Korean Language. As a result of the analysis, as proficiency increases, the overall frequency of '의' increases and the number of meaning senses used increases. However, the frequency of errors also increases with it. As for the usage pattern of each sense, the meaning of 'ownership, belonging' is the most frequent, and followed by 'acting entity', 'kinship, social relations', and 'relationship(area)'. In conclusion, the meanings of 'acting subjects' and 'relationships(area) need to be supplemented with explicit education. Other meanings need to be discussed, and decisions should be made in consideration of learning purpose and proficiency.

Construction processes are highly repetitive. A resource entity continuously cycles through work tasks that processes or uses resources. Web-CYCLONE (Halpin 1992) has been accepted as a useful tool for modeling and analyzing a specific operation. However the system has a lack of practicality as follows: (1) it does not efficiently record and keep track of operation models in a database; (2) it does not provide the functions which facilitate to retrieve corresponding model and to update local variables of the model using observed data; (3) it does not automate the complex process that executes simulation experiment, analyzes simulation outputs and generates a report on behalf of the practitioners. Therefore, practitioners have a difficulty in reusing, modifying and analyzing the existing operation models. This study introduces a Client/Server based CYCLONE that improves above-mentioned limitations in the existing Web-CYCLONE. The system was illustrated by revising CSPU in practice.

The amount of data a related to a person is so substantial that it appears that a digital version of them can be built thereon. They are usually handled as personal information, and the attempts made to understand personal information have led to bundling and unbundling of various data, yielding numerous fragmented categories of personal information. Therefore, we attempt to construct a generalizable lens for a deeper understanding of person-related data. We develop a theoretical framework that provides a fundamental method to understand these data as an entity of a digitally represented person based on literature review as well as the concepts of inforg and infosphere. The proposed framework suggests person-related data consist of three informational inforg dimensions that can preserve the archetype of a person, form, content, and interaction. Subsequently, the framework is examined and tested through several analyses in two different contexts: social media and online shopping mall. This framework demonstrates the suggested dimensions are interrelated with certain patterns, the prominent dimension can determine the data characteristics, and the dimensional composition of data types can imply the characteristics of the digitally represented person in certain contexts.

Since the recently established obligation to implement safety and health measures for specialized workers as outlined in the Occupational Safety and Health Act (OSHA) for nine occupations in January 2020 and five occupations in November 2021, there is a need to verify and inspect the on-site operation of related systems. After a comprehensive fact-finding survey and risk factor analysis, it is necessary to examine the responsibility for on-site safety and preventive measures, along with the roles and responsibilities of specialized workers. Stakeholder analysis is essential to identify the fundamental problems related to the responsibility stipulated in the purpose of OSHA and to explore the entity responsible for implementing safety measures. Therefore, in this paper, we discuss the topic of implementation based on legal standards for on-site safety and preventive measures. Additionally, we develop a role model for appropriate safety measures, outlining the dynamic relationship between those who provide labor and those who provide labor in the context of specialized workers.

Primary tuberculous osteomyelitis involving the mandible represents less than 2% of skeletal locations. In this paper, we report a case of mandibular tuberculosis (TB) detected after histopathological analysis of the surgically resected specimen during surgical management of a suspected case of ameloblastoma. A 14-year-old male patient presented to us with history of right-sided chin swelling. The clinical examination revealed a swelling, involving right body and parasymphysis of mandible, measuring approximately 6 cm in length and 2 cm in width, extending from right lateral incisor till the first molar. Radiological scans revealed a large multiloculated osteolytic expansive lesion measuring 52 × 20 × 18 mm. Excision of the lesion was performed and reconstruction was done with iliac bone grafting. The histopathological findings revealed a granulomatous lesion, suggestive of tuberculous osteomyelitis. The patient was successfully treated with standard multidrug therapy. One year after completion of therapy, there were no signs of recurrence. Primary mandibular TB is an extremely rare entity. Its clinical presentation is not specific. Radiologically, TB has no characteristic appearance. The positive diagnosis is based on histology. Primary mandibular TB is rare and should be kept among differential diagnoses in susceptible population and in endemic areas.

Investment Agreement is to be a part of FTA, as negotiating together both trade and investment. For example, it has a separate chapter about investment in KORUS FTA contract and is more detailed and inclusive than BIT contents which are traditional investment provisions. It is called to the investment norm of FT A. The investment agreement lures a foreign investment by providing the environment which is stable to the foreign investors. Hence, it plans in goal for the economic development of the home country. In international investment, the arbitration award cases are coming out to be divided into two parts applying MFN provisions in investor protective principles and dispute resolution process; the tendency of broad interpretation and the tendency of limited interpretation. In the case of RosInvest Co UK Ltd v. the Russian Federation awarded in 2007, the arbitration tribunal interprets that the application scope of MFN provisions contain the more lucrative dispute provision than other BITs without limitations in entity right of the investor. This judgment is the same view as arbitration tribunal position of Maffezini case. The arbitration tribunal of Plama case has kept out an assertion magnifying the arbitration tribunal's jurisdiction. That is, for applying more inclusive investor-nation resolution method from different treaty, tribunal mentioned that MFN provision had to see clearly a point of applying the investor-nation dispute resolution method. Dispute resolution process providing inclusive MFN provision has both the tendency of broad interpretation and the tendency of limited interpretation. It needs ceaselessly to do the monitoring about cases of arbitration award. In conclusion, the point where MFN provisions are applied conclusively is recognized, but it is still controversial whether or not to magnify the jurisdiction of arbitration tribunal applying MFN provisions. Therefore, it does not exist clear principle in the theory or in the award eases about the application scope for entity protection provision of MFN. Hence, The Korean government of Korea and local autonomous entities needs to keep their eyes on the trend of the international arbitration award cases in relation to the investment dispute for the future. Also, Korean government or local self-governing group must consider MFN provisions when they make a contract of international investment treaty such as writing concretely the application of MFN provisions from KORUS FTA.

The role of a GIS as a tool for a national information infrastructure can best be fulfilled once GIS standards are implemented. In this paper, we have identified what the contents of GIS standards in other countries are, and what should be the future direction for implementing a nation's GIS standards. Based on a detailed review on GIS standards in the USA, Australia, Japan and the United Kingdom, we derived the following: (1) A nations's GIS standards should include both geographic information content standards and geographic information service standards: (2) A nation's GIS standards should be a profile of ISO GIS standards: (3) Each GIS standards should be developed on the bassis of the Entity-Relationship Model using Unified Modeling Language: and (4) Experts in GIS should pay much more attention on studies on GIS service standardization. As for building the national GIS Standards for Korea, we recommend both GIS Content Standards and GIS Service Standards be simultaneously developed. GIS Content Standards include geographic feature content standard, feature classification standard, portrayal standard, rules for application standards, spatial reference model and terminology. GIS Service Standards include standards for data sharing such as metadata standard and transfer standard, quality standard, quality principle and portrayal standards.
