Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

In this paper we present a consistent semantic model between a natural language and a relational database. The objective of the model is to transform Korean inquires into semantically equivalence SQL expression. We describe the conceptual graph translator, which translates a conceptual graph - the result of semantic analysis to the korean inquires -into a database-suitable conceptual graph. We use a conceptual graph to represent our semantic model of the database. The translator generates a conceptual graph by using a synonym dictionary for queries of various patterns. Beginners are able to retrieve data without knowledge in a specific field. As a result, more practical system with unrestricted inquires can be expected.

In recently, much pesticides were used for control of agricultural and medical insects. The result of using pesticides were social problem because of environmental pollutions with pesticides in urban and farm village. The environmental pollutions were very serious. This experiment was conducted to eluciated of reduce to environmental pollution bring about using pesticides (organophosphates, carbamates, pyrethroids, and insect growth regulators) for control of medical insects(house fly, Musca domestica L and mosquito, culex pipiens pallens copuillett) and carried out the method of pest control. And the result are summarized as follows. The Kyongbuk house fly strain treated with pyriproxyfen on third instar larvae were very high mortality and low emergence. When use it, at the same time, we can reduce degree of environ-mental pollution and house fly populations. Using of imidan was effective in Seoul and Chungnam house fly strains. In mosquito larvae, the efficacy of icon to chungbuk strain, propoxur to Chungnam and Chungbuk strain, imidan to Kyongbuk strain, fenthion to Chungnam strain were excellent. In result of spraying imidan and icon on adult mosquitoes, the efficacy of icon was excellent than imidan. In esterase electrophoresis, third instar larvae of Chungnam house fly strain fed on artificial diet mixed with pyriproxyfen LC50 were very high activity of -Est-αl in early stage(second day after third instar larvae fed on diet), and the activity of Est-αl was very strong in late stage(se-vents day after third instar larvae fed on diet). In Kyongbuk strain, -Est-αl and Est-αl were detected in early and late stage, and activities of and -Est-αl and Est-αl were detected almost equally in late stage. It was very characteristic in this experiment. Third instar larvae fed on diet mixed with pyriproxyfen LC95 were detected -Est-αl and Est-αl almost equally. It was believed moulting control in insects. In electrophoresis with head, thorax, abdomen of house fly adult, -Est-α2 -Est-αl, Est-αl, Est-α2, Est-α3 were detected in abdomen in susceptible strain and only -Est-αl, was net detected in thorax -Est-αl, was detected in head, thorax and abdomen of Chungbuk strain and -Est-αl was detected in head, -Est-α2 in thorax of same strain. Activities of chitinase in late instar larvae of house flies fed on artificial diet mixed with pyrip-roxyfen LC50 and LC95, in pyriproxyfen LC95, analysised low and high again with the lapse of time in Kyongbuk strain. This was believed that the activity of chitinase was became high just before emergence. The result of filter paper test with mosquitoes were very high index(265) of esterase activity in Chungnam strain among all mosquito strains. In this reason, we can suppose that used pyrip-roxyfen (IGR) in Chungnam area for control pest. In this reason, it was more reasonable made use of pyriproxyfen than other pesticide in Chungnam area.

In this paper, we present an index structure and search method modified bash for the efficient and fast searching of shape information in large image databases. The proposed index structure is made up of 4 dimensional values by analyzing a range of feature vectors extracted by invariant moment set. We also propose a search method based on the proposed index structure that increases search speed by reducing search space. Experimental results show the effectiveness of the proposed index structure and search method.

Subacute combined degeneration is a metabolic disorder of the spinal cord caused by vitamin B12 deficiency. A 72-year old man was admitted with weakness and tingling sensation of the bosh upper extremities. 9 years ago, he was diagnosed as having stomach cancer. So total gastrectomy with splenectomy was done at that time. The complete blood cell counts and morphology revealed megaloblastic anemia. Nerve conduction velocity study(NCV), electoromyography(EMG) and somatosensory evoked potentials(SEP) showed diffuse sensorimotor peripheral neuropathy. Magnetic resonance imaging(MRI) showed an increased T2-weighted signal, mild decreased T1-weighted signal, and slight contrast enhancement of the posterior columns of the cord in the cervical and upper thoracic spinal region. He was treated with vitamin B12 supplements and improved gradually. If abnormal sensation and muscle weakness was developed after gastrointestinal surgery, subacute combined degeneration should be considered in the differential diagnosis. We describe MRI findings of a typical case of subacute combined degeneration, which was induced by total gastrectomy.

석청에 포함된 grayanotoxin에 의해 독성 작용이 나올 수 있으며, 이러한 독성 작용은 일반적으로 24시간 이내 저절로 회복된다. 최근에 본 저자들은 석청 복용 후 발생한 심실빈맥을 경험하였기에 보고하는 바이다. 49세 남자가 호흡곤란으로 내원하였으며, 내원당시 분당 40회 정도의 동성 서맥이 관찰되었고, 수액을 투여하던 중 심실 빈맥이 발생하였다. 항부정맥제를 투여 후 정상 동율동으로 전환되었으며, 특별한 이상 없이 4일 후 퇴원하였다. Mad-honey intoxication caused by the consumption of honey producted from the nectar of rhododendrons. The grayanotoxins cause the intoxication. The toxic effects of mad-honey poisoning are rarely fatal and generally last for no more than 24 hours. We experienced one case, a 49 years-old man who presented with dyspnea after ingestion of mad-honey. He showed marked sinus bradycardia with < 40 beats per minute on admission. The cardiac rhythm was changed to ventricular tachycardia immediately. These features resolved completely in 24 hours with continuous infusion of amiodarone(600 mg per day) and fluids. We report the case of intoxication of mad-honey as a presentation of fatal cardiac arrhythmia.

저자들은 호흡곤란, 흉부불쾌감, 심계항진 등을 주소로 내원한 환자에서 경흉부 및 경식도 심초음파 검사상 주폐동맥에서 이완기에 전행하는 지속적인 혈류의 흐름을 관찰하고, 관상동맥 조영술을 통해 좌전하행지 중간부위와 우관상동맥 근위부에서 각각 기시하여 공통경로를 이루면서 주폐동맥으로 유입되는 양측성 관상동정맥루를 보이는 드문 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. A coronary arteriovenous fistula is infrequently encountered vascular communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common congenital anomaly that can affect coronary perfusion. Bilateral involvement of coronary fistula constitutes an uncommon subgroup of coronary arteriovenous fistulas. A 69 year-old female patient presented with chest discomfort, palpitation, and dyspnea. In the echocardiography, doppler color flow imaging visualized abnormal flow signals with mosaic appearance in the main pulmonary artery during diastolic phase. Coronary angiography revealed arteriovenous fistula arising from the left anterior descending artery and the right coronary artery. Both coronary arteriovenous fistulas drained into the main pulmonary artery. We report a case of bilateral coronary arteriovenous fistula that was confirmed by echocariography and coronary angiography.
