A 3-year-old Cocker spaniel was presented for evaluation because of a mass protruding from the vulva. This mass confirmed the presence of an internal bone in clitoris on the radiography. We recommended to the owner of the surgical removal of the gonads and uterus as well as the excision of the enlarged clitoris and os clitoris. The dog had gonads in the region of where the ovaries were located and presented what appeared to be a bicornate uterus and ductus deferens. Histological analysis revealed a morphologically normal uterus and two testes with their epididymis and ductus deferens. Karyotyping revealed a normal female chromosome constitution (78, XX), and polymerase chain reaction (PCR) identified the absence of Sry. Based on these findings, the patient was diagnosed with Sry-negative XX sex reversal.

Purpose: Sternocostoclavicular hyperostosis (SCCH) is a disease of unknown etiology, which is characterized by periosteal reaction and endosteal hyperossification of the sternum, clavicles and upper ribs as well as ossification of the surrounding soft tissue. SCCH is a well recognized but uncommon condition which is important differential diagnosis to consider to avoid misdiagnosis and to differentiate the condition from malignant process. But few studies have reported long-term clinical result of SCCH. We report long-term clinical result of SCCH. Materials and Methods: From 1986 to 2000, 17 cases of SCCH were followed up over two to 14 years. We evaluated the radiologic, pathologic and clinical results. Results: Four men and thirteen women were studied. The age when first symptom appeared were raged from17 to 60(average-48.7) There are no specific bacteriological, serological or histological finding. Usually a permanent increase in the erythrocyte sedimentation rate is found. The radiological examination showed the signs of proliferate destructive arthritis in most case. The majority of patients respond to NSAIDs and antibiotics. Conclusion: Sternocostoclavicular hyperostosis is uncommon benign condition, but important condition in the differential diagnosis of inflammatory or malignant process of this joint.

The purpose of this study was to compare the values of tongue pressure (TP), lip closing pressure (LCP), right buccal pressure (RBP), and left buccal pressure (LBP) and check the intraoral muscle imbalance and observe the changed values according to the myofunctional therapy (MFT) period. The MFT with a prefabricated appliance was performed on patients with certain muscular dysfunctions due to oral habits. And the improvement of perioral muscles was evaluated using a balloon-based pressure measurement. The group consisted of 21 patients with oral habits such as chronic mouth breathing, finger sucking, lip sucking, tongue thrusting, and atypical swallowing habits. When comparing the two groups before treatment, there was a significant difference in TP and LCP values. The TP increased the most in the first month since the start of myofunctional therapy, and the LCP increased the most between 3 and 6 months after treatment began. The values of TP, LCP, RBP, and LBP in the control group measured before treatment were very similar to the results of the experimental group 6 months after the myofunctional therapy. When the MFT was steadily performed, it was possible to observe a noticeable increase in the tongue and lip closing pressure. At least 6 months of myofunctional therapy is recommended for patients with intraoral muscle imbalance due to oral habits.

The methods of selection through observations and recommendations were introduced in the process of recruiting new students for the science education institutes for the gifted attached to 25 universities recently. This paper itemized the methods of screening through observations and recommendations. This paper also analyzed the problems with the methods and attempted to create plans for their improvement. The methods of selection through observations and recommendations led to the positive results that students' usual activities and attitudes in the classroom were reflected on the evaluation and that the cost of their private lessons was also reduced. However, the methods showed a few problems that need to be corrected. We point out problems occurring with examining their documents for submission and interviews. It was not easy to grade candidates' gifts, creativity, potential and development within the contents of the documents and the limited time of conducting interviews. On the plans for the developments of the implemented methods of selection through observations and recommendations, we have several suggestions. The chances for teachers' in-service training of learning the methods of selection through observations and recommendations need to be expanded. The interview needs to be enhanced and to have the same weight as the document screening. To secure the continuity of the education for the gifted, the clear guidelines from the Ministry of Education, Science, Technology along with the cooperation of the education institutes for the gifted are essential.

하이퍼그래프(hypergraph)는 실세계의 여러 객체가 함께 형성하는 복잡한 그룹 관계를 하이퍼엣지(hyperedge)로 정보 손실 없이 모델링할 수 있는 새로운 데이터 구조이다. 하이퍼엣지 예측(hyperedge prediction task)이란 하이퍼그래프로 표현된 실세계 네트워크에서 아직 관찰되지 않은 그룹관계 혹은 미래에 발생할 가능성이 높은 관계를 예측하는 것으로, 단백질 상호작용 분석(PPI), 추천시스템, 소셜 네트워크 분석 등 다양한 응용 분야에서 활용된다. 그러나, 하이퍼엣지 예측은 심각한 데이터 희소성 문제로 정확한 예측이 어렵다는 근본적인 한계를 지닌다. 이러한 한계를 완화하기 위해 다양한 네거티브 샘플링(negative sampling) 기술이 활용될 수 있는데, 아직까지 각 샘플링 기술이 하이퍼엣지 예측 정확도에 미치는 효과에 대해 충분히 연구되지 않았다. 본 논문에서는 하이퍼엣지 예측에 활용되는 다양한 네거티브 샘플링 방법의 효과를 분석한다. 실험 결과를 통해, 네거티브 샘플링 기법과 포지티브와 네거티브 하이퍼엣지 수의 비율에 따른 정확도 변화 양상을 분석한다.

For our survey of insecticidal resistance of Palm thrips (Thrips palmi Karny), we established the discriminating time (DT) and concentration (DC) of nine insecticides, and we conducted a bioassay about seven local populations via leaf-dipping methods. The discriminating times of the recommended concentration (RC) were 24 h at emamectin benzoate EC and spinetoram SC, 48 h at chlorfenapyr EC, 72 h at spinosad SC, cyantraniliprole EC, acetamiprid WP, dinotefuran WG, imidacloprid WP and thiacloprid SC after treatment. The DC estimated the concentration which showed the difference within the mortalities of these local populations. The DCs were emamectin benzoate EC $0.013mg\;L^{-1}$ (RC, $10.8mg\;L^{-1}$), spinetoram SC $0.125mg\;L^{-1}$ (RC, $25.0mg\;L^{-1}$), chlorfenapyr EC $0.25mg\;L^{-1}$ (RC, $50.0mg\;L^{-1}$), spinosad SC $0.083mg\;L^{-1}$ (RC, $50.0mg\;L^{-1}$) and cyantraniliprole EC $5.0mg\;L^{-1}$ (RC, $50.0mg\;L^{-1}$), and DCs of neonicotinoids were their RCs, that is, acetamiprid WP (RC, $40.0mg\;L^{-1}$), dinotefuran WG (RC, $20.0mg\;L^{-1}$), imidacloprid WP(RC, $50.0mg\;L^{-1}$) and thiacloprid SC (RC, $50.0mg\;L^{-1}$). From our investigation into the resistance of the local populations with DT and DC application, the neonicotinoid insecticides have shown a high resistant level for all the local populations, and the other insecticides have demonstrated low or non-resistance. In the use of neonicotinoid insecticides to control Palm thrips, one must take caution. As a result, the establishment of DT and DC in the single dose bioassay method was helpful for surveying the insecticide response dynamics and the development of an insecticide resistance management strategy.

Purpose : This post-marketing surveillance study (NCT00750360) assessed the safety and reactogenicity of an inactivated, trivalent split-virion influenza vaccine licensed for use in the Korea since 2002. Methods : Eight hundred and eighty three subjects aged 6 months received a single dose of the ${\geq}$ vaccine; an additional dose was administered to those aged <9 years and unprimed with an influenza vaccine. Four hundred and eleven subjects used diary cards to record safety information; this report presents data from these subjects. Incidence of solicited local, general and unsolicited adverse events (4-days and 21-days post-vaccination follow-up periods, respectively) were recorded. Serious adverse events (SAEs) were recorded throughout the study period. Results : Injection site pain (subjects aged <6 years: 12.6% of subjects, ${\geq}$6 years: 34.7%), fever (<6 years: 1.3%) and myalgia (${\geq}$6 years: 13.9%) were the most frequently recorded solicited local and general adverse events. Grade 3 solicited adverse events were reported by ${\leq}$4.0% subjects. No vaccine-related SAEs were recorded (KFDA criteria). Conclusion : Considering the vaccine's well-established immunogenicity and its favourable safety and reactogenicity profile across all age groups and its high coverage rate in Korea, it may be recommended as a candidate to facilitate annual seasonal influenza vaccination for all ages as part of the Korean National Immunization Program.

In partial edentulous patients, implant-assisted removable partial denture which provide additional retention and support by placing a small number of implants in strategic positions might be suitable treatment. This case of patient with loss of maxillary posterior teeth and moderate to severe wear of residual dentition, three implants were placed in the maxillary anterior edentulous area and then surveyed bridges were made including remaining anterior natural teeth. Posterior edentulous area was restored with distal extension removable partial denture (RPD). In addition, the worn mandibular natural teeth were restored with fixed prostheses. As a result, reduced vertical dimension and collapsed occlusal plane were rehabilitated, and improved functionally and aesthetically. The purpose of this case was to report the results of three-year follow-up of full mouth rehabilitation with anterior implant surveyed bridges and distal extension RPD.
