  • The recognition of a relatively big and rarely movable object. such as refrigerator and air conditioner, etc. is necessary because these objects can be crucial global stable features of Simultaneous Localization and Map building(SLAM) in the indoor environment. In this paper. we propose a novel method to recognize these big objects using a sequence of 3D scenes. The particles representing an object to be recognized are scattered to the environment and then the probability of each particles is calculated by the matching test with 3D lines of the environment. Based on the probability and degree of convergence of particles, we can recognize the object in the environment and the pose of object is also estimated. The experimental results show the feasibility of incremental object recognition based on particle filtering and the application to SLAM

  • Facial feminization surgery (FFS) incorporates aesthetic and craniofacial surgical principles and techniques to feminize masculine facial features and facilitate gender transitioning. A detailed understanding of the defining male and female facial characteristics is essential for success. In this first part of a two-part series, we discuss key aspects of the general preoperative consultation that should be considered when evaluating the prospective facial feminization patient. Assessment of the forehead, orbits, hairline, eyebrows, eyes, and nose and the associated procedures, including scalp advancement, supraorbital rim reduction, setback of the anterior table of the frontal sinus, rhinoplasty, and soft tissue modifications of the upper and midface are discussed. In the second part of this series, bony manipulation of the midface, mandible, and chin, as well as soft tissue modification of the nasolabial complex and chondrolaryngoplasty are discussed. Finally, a review of the literature on patient-reported outcomes in this population following FFS is provided.

  • The purpose of this study was to analyze the housing tenure choice decisions of older households, with focus on the activity constraints of the householders. For analysis, the probit model based on the data of the householders over 55 years of age from the 2015 KLIPS data was implemented. The research findings indicate that the ownership choice probability decreases when the head of the household has activity or social activity constraints. If there is an activity restriction, it is considered that the possibility of self-residence will be low due to the increase in medical expenses, the possibility of participation in economic activities will be low, the possibility of early retirement will be high, and the income will decrease. Therefore, if the head of the household has a personal or social activity constraint, such case is more likely to be categorized as falling under the poor residential group. This result suggests that the activity constraint can be utilized as a useful index for the housing welfare policy considering physical vulnerability.

  • This study aimed at exploring the primary motivations in the behavior of MNCs' setting up R&D Labs in China, four main subjective motivations were founded. R&D Labs consisted of the following four types: local market support Labs, local technology support Labs, global technology center, and internationally interdependent Labs.he choices of the R&D Lab type features are different because of the various R&D investment motivations. Provided that MNCs' investment motivations in China are in order to obtain Chinese markets and customers, local market support Labs are supposed to be chosen so as to support Chinese markets; provided that investment motivations are in order to gain talents and science and technology resources, global technology centers are supposed to be used to achieve the highest synergy result; provided that investment motivations win an absolute competitive advantage in China, local market support Labs are extremely necessary in preoccupying markets; last but not the least, provided that investment motivations are environmental owing to their instability, local technology support Labs are a good choice for their relatively low R&D expenses.

  • Accurate forecasting of volatility is of considerable interest in financial volatility research, particularly in regard to portfolio allocation, option pricing and risk management because volatility is equal to market risk. So, we attempted to delineate a model with good ability to forecast and identified stylized features of volatility, with a focus on volatility persistence or long memory in the Australian futures market. In this context, we assessed the long-memory property in the volatility of index futures contracts using three conditional volatility models, namely the GARCH, IGARCH and FIGARCH models. We found that the FIGARCH model better captures the long-memory property than do the GARCH and IGARCH models. Additionally, we found that the FIGARCH model provides superior performance in one-day-ahead volatility forecasts. As discussed in this paper, the FIGARCH model should prove a useful technique in forecasting the long-memory volatility in the Australian index futures market.

  • Purpose: Thrombosis of the portal vein, known as pylephlebitis, is a rare and fatal complication caused by intraperitoneal infections. The disease progression of superior mesenteric venous thrombosis (SMVT) is not severe. This study aimed to determine the clinical features, etiology, and prognosis of SMVT. Materials and Methods: We retrospectively reviewed the medical records of 41 patients with SMVT from March 2000 to February 2017. We obtained a list of 305 patients through the International Classification of Disease-9 code system and selected 41 patients with SMVT with computed tomography. Data from the medical records included patient demographics, comorbidities, review of system, laboratory results, clinical courses, and treatment modalities. Results: The causes of SMVT were found to be intraperitoneal inflammation in 27 patients (65.9%), malignancy in 7 patients (17.1%), and unknown in 7 patients (17.1%). Among the patients with intraperitoneal inflammation, 14 presented with appendicitis (51.9%), 7 with diverticulitis (25.9%), and 2 with ileus (7.4%). When comparing patients with and without small bowel resection, the differences in symptom duration, bowel enhancement and blood culture were significant (P=0.010, P=0.039, and P=0.028, respectively). Conclusion: SMVT, caused by intraperitoneal inflammation, unlike portal vein thrombosis including pylephlebitis, shows mild prognosis. In addition, rapid symptom progression and positive blood culture can be the prognostic factors related to extensive bowel resection. Use of appropriate antibiotics and understanding of disease progression can help improve the outcomes of patients with SMVT.

  • This study aims to examine the transformation of the heroic narrative in the successful Korean Wave drama. In this study, TV drama "Descendants of the Sun" which gained tremendous popularity at home and abroad was considered to be an example of the heroic narrative model proposed by Vogler. Further, two analysis points were identified as the critical factor of success: modern transformation and global transformation. Modern transformation is about distinct characteristics of Korea, found in three primary factors of the work: the setting up of a character, the development of events and the background set-up. Global transformation features universal value to attract foreign viewers by lowering cultural discount. In "Descendants of the Sun", humanism is considered to broaden the horizon of the work by affecting above three factors. In conclusion, It is the proper combination of these dual transformations that globalize Korean drama. In this regard, this study will be a meaningful attempt to shed light on the storytelling strategy of Korean dramas in terms of the heroic narrative.

  • Thought-action fusion (TAF) is a tendency to blindly assume causal relations between their thoughts and external reality. On the other hand, cognitive fusion (CF) is a tendency to take internal experiences, such as thoughts and feeling, literally rather than view them as random events. However, these two terms are often confusedly used and, in fact, have conceptual overlaps. Therefore, this study aimed to identify their distinctive features through a comprehensive review of the definition, origin, measurements and clinical implications especially on the understanding of obsessive-compulsive symptoms. The cognitive-behavioral concept of TAF is confined to erroneous and maladaptive beliefs about the connection between thoughts and behaviors. The CF is a broader construct that entails taking thoughts and feelings as facts and engaging or struggling with them such that the quality of life is lowered. They also have different theoretical backgrounds, developing processes and therapeutic approaches. From the perspective of the obsessive-compulsive disorder, both concepts have been studied as mid-structures for this illness. Recently, the effectiveness of psychological therapies related to these concepts such as defusion therapy has been tested. However, it is yet still in its infancy. In the future, complementary advances between the two concepts with studies on biological substrates is needed.

  • This paper reports the project of arranging archives of Administrative Headquarters of the Jogye Order. It illustrates the whole process of preliminary survey, arrangement, appraisal and description of the archives. One of the distinctive features of the project lies in its focus on practical considerations. In other words, it has avoided blindly following theoretical recommendations made by previous efforts. First step of the project has been to review the current state of the archives through preliminary survey as well as analysis of related regulations. Second step has followed to establish actual process of classifying, appraising, describing, filing and designing storage facility management as well as a computerized archival management system. In this process, every concern has been given to prevent records and archives from physical damage and to ensure their intellectual order kept so that archival information could be re-constructed and usability and efficiency of the records could be secured. Major contributions made by the project can be found in that it has reviewed the volume of administrative archives created and held by Jogye Order and improved the overall efficiency of as well as information sharing among personnel at the Headquarter. The most notable accomplishment could be, however, found in that the project has helped the personnel to rediscover their own history from their records, rather than from their memory. From the theoretical perspective of archival science, the meaning of the project can also be found in that it has provided with the starting point toward establishing organizing methodology for organizational archives including religious archives. Arranging archives of an organization requires archivists to respect theories and principles, but at the same time, adequate attention should be paid to reflect idiosyncratic characteristics of the organization. General methods applicable to a wider range of archives could be derived from the very endeavor. Though impossible in a short period of time, it could be accomplished by accumulating theoretical and practical knowledge and experience.

  • This study analyses land related problems and its features which stems from a concession established by the imperialist countries from the late Joseon Dynasty to the Japanese colonial period. In order to achieve the purpose of this study, literature review related to the installation of the treaty ports and a concession was conducted and a chronological analysis was applied. As a result of the study, the East China Sea and the Japan were opened by the Western powers in prior to the East Asia region, Korea was an open harbor port led by Japan, which had experience installing an open harbor. In this circumstance there was a system that allowed foreigners to freely reside and exercise exertion rights (exercise one's extraterritoriality), which was a disadvantage to Joseon. In addition, the Japanese-style land area unit "Pyeong" was used in Japan's highly influential prefecture, and later became the basis of the unit of land used in the 1910 land survey project.
