  • When the mandible performs opening movement, the condyle-disk complex conducts sliding movement along the articular eminence. Thus, anatomic configuration of articular eminence is very important to normal movement of TMJ. The purpose of this study was to measure the posterior slope of the articular eminence and evaluate the effect of a pathologic bone change in the condylar head on the stiffness of articular eminence, and compare the differences of the articular eminence slope by gender and age using dental cone-beam CT. As using i-CAT Cone-Beam Computed Tomography, the CT images of 204 TMJs of 102 patients(43 men and 59 women, mean age: 37.7 years) who were diagnosed at Wonkwang University Sanbon Dental Hospital were evaluated. All images were converted into a TMJ analysis mode to observe the continuous sagittal section images and coronal section images of the joints. To observe and assess bone changes in the condyle, three dentists measured the stiffness of the articular eminence on the same images, and when two of the three dentists agreed on their reading, these results were adopted and recorded. The articular eminence slope, considering the condylar anatomic configuration, was measured in three regions, namely, lateral part, central part, and medial part of the condyle. In the cases of a normal condyle(NCBC) and a condyle(CBC) with bone change, the articular eminence slopes were $57.0^{\circ}$(NCBC) and $51.8^{\circ}$(CBC) at the medial part, $57.9^{\circ}$(NCBC) and $52.4^{\circ}$(CBC) at the central part, and $55.1^{\circ}$(NCBC) and $49.5^{\circ}$(CBC) at the lateral part of the condyle. And the articular eminence slope of the condyle with bone change demonstrated less steepness than that of normal condyle (p<0.05). The articular eminence slope showed mediolaterally that it was the steepest at the central, followed by at the medial, and at the lateral (p<0.05). There were no significant differences by the gender and the age (p.0.05).

  • This study addressed an ill-understood issue of a price response model and a monopolistic price interval of fashion goods. The concept of monopolistic price interval introduced by Gutenberg has been rarely applied to the fashion goods, which is known as price sensitive goods. Thus, this study examined the price insensitive zone of the blue jean. The data of 268 respondents were analyzed using Choice-based Conjoint (CBC) analysis and t-test. Considering brand consideration set as a price determinant, we found the presence of monopolistic price interval of the jean. The results obtained from the CBC analysis showed that the bigger the size of brand consideration set, the shorter the monopolistic interval. This implied that the consumer who had a small brand consideration set was more likely to have a longer monopolistic price interval than the one who had a large brand consideration set, since the consumer with a small consideration set tended to value brand itself more than price. Although significant monopolistic price intervals were shown only for the three jean brands out of the seven, to reduce the size of brand consideration set and to increase brand loyalty were found important in maximizing firms'financial profits.

  • Epilepsy is a disorder that causes recurring seizures, and the most objective and useful test for detecting epilepsy is the electroencephalogram (EEG). The subjects of this study are 244 patients who received an EEG after being diagnosed with epilepsy at Seoul National University Hospital in 2014, and who have agreed to the purpose of the study. Based on the EEG results, subjects were divided into normal and abnormal groups with 122 subjects in each group, regardless of their gender and age, to investigate the correlation of EEG and complete blood cell count (CBC) test results. The four significant categories that displayed significant correlation between EEG results and CBC hematological measurements in this study were the white blood cell (WBC), red blood cell (RBC), neutrophil, and lymphocyte tests. The WBC (p<0.05) and neutrophil (p<0.01) showed a positive correlation with EEG results, while RBC (p<0.05) and lymphocyte (p<0.01) showed a negative correlation. One of the limitations of this study is that it is lacking the blood test result analysis according to the types of anti-epilepsy medicine. However, the analysis of EEG results by the same disease has significant meaning. Therefore, further studies are needed to statistically analyze more data in the future.

  • In this paper a simple and effective call admission control (CAC) scheme is proposed for the emerging interleave-division multiple-access (IDMA) systems, supporting a variety of traffic types and offering different quality of service (QoS) requirements and priority levels. The proposed scheme is signal-to-interference-plus-noise ratio (SINR) evolution based CAC (SE-CAC). The key idea behind the scheme is to take advantage of the SINR evolution technique in the process of making admission decisions, which is developed from the effective chip-by-chip (CBC) multi-user detection (MUD) process in IDMA systems. By virtue of this semi-analytical technique, the MUD efficiency can be estimated accurately. Additionally, the computational complexity can be considerably reduced. These features make the scheme highly suitable for IDMA systems, which can combat intra-cell interference efficiently with simple CBC MUD. Analysis and simulation results show that compared to the traditional CAC scheme considering MUD efficiency as a constant, the proposed SE-CAC scheme can guarantee high power efficiency and throughput for multimedia traffic even in heavy load conditions, illustrating the high efficiency of CBC MUD. Furthermore, based on the SINR evolution, the SE-CAC can make accurate estimation of available resource considering the effect of MUD, leading to low outage probability as well as low blocking and dropping probability.

  • A six year-old male Maltese dog was presented to the Konkuk University Veterinary Teaching Hospital (KUVTH) with mass in right scapula region. Physical examination, radiography, magnetic resonance imaging (MRI), complete blood count (CBC), serum biochemistry, cytological analysis of fine needle aspiration and histopathological examination were performed. There was no remarkable finding in CBC. Alkaline phosphatase (ALP) was found to be increased in serum chemistry profile. Osteolysis was seen on radiographs of the scapula. MRI revealed mixed signal intensity in scapula. Cytological examination of fine-needle aspirate (FNA) was suggestive of sarcoma. We confirmed that the neoplastic cells were fibrosarcoma by immunohistochemical and Masson's trichrome staining.

  • A 11-year-old neutered male Maltese dog was vaccinated with a rabies vaccine (Rabisin®, Boehringer Ingelheim International GmbH, Germany) subcutaneously at a local animal hospital. One hour after vaccination, purpura with edema was observed at the injection site and severe thrombocytopenia (0 K/μL) was noted on a complete blood count (CBC). No specific findings were found in serum chemistry, electrolyte, blood gas analysis, and coagulation tests. The patient was hospitalized and administered antihemorrhagic agents (vitamin K, desmopressin), antihistamines (chlorpheniramine) and corticosteroids (methylprednisolone sodium succinate). On a repeat CBC, mild anemia had developed, thrombocytopenia was still noted, and autoagglutination was observed on a saline agglutination test (SAT). A polymerase chain reaction panel for infectious agents (e.g., Babesia spp.) was negative. The diagnosis was secondary immune-mediated thrombocytopenia (IMT) with immune-mediated hemolytic anemia (IMHA) associated with vaccination. Therefore, the immunosuppressants (prednisolone, and mycophenolate mofetil) were administered. Six days after drug administration, new lesion was not observed, and the previous lesions were significantly improved. It gradually improved and 4 weeks after hematocrit and platelet recovered to normal levels. It was maintained for 6 months without recurrence of related symptoms. Based on patient's history and test results, the patient was diagnosed with Evans' syndrome associated with rabies vaccine.

  • The purpose of this study was to establish the role of master gardener coordinators and develop an education program to enhance their job competencies. To analyze and develop the new job of master gardener coordinator, we used the CBC method for curriculum development. The research findings can be summarized as follows. The analysis result of need and importance of education based on the performance level and demand level revealed 20 core competencies, which were classified into organizational education, learning by experience, individual learning, low-priority competencies for program development, with focus on the importance and need for education. The 17 courses are comprised of Eastern and Western Garden History, Understanding of Community Garden, Garden Aesthetics and Environmental Design, Master Gardener's Mission & Management, Garden Plants, and Garden Design and Practice etc. and the curriculum is 33 hours in total. The master gardener coordinator education program was conducted on 73 rural extension workers and the curriculum was evaluated by those who completed the program. The overall satisfaction was 4.29 and 97.1% of the trainees decided that the program would help them perform their duties. The analysis result discovered that all 20 core competencies increased after the program. As a result of conducting contingent valuation to determine the value of the program, willingness to pay (WTP) per hour was KRW 33,223 and the total WTP was KRW 1.096 million, which, when multiplied by 73 participants, is approximately KRW 80.008 million. This is relatively higher than the budget used (KRW 22.943 million), indicating that the program is worth it.
