Uterus didelphys with unilateral obstructed hemivagina and ipsilateral renal agenesis usually presents after menarch with progressive abdominal pain during menses secondary to hematocolpos, and indeed a very rare congenital anomaly due to Mullerian duct malformation. An accurate and prompt diagnosis is of importance to permit treatment and to assure the future fertility of the patient. Pelvic ultrasound, physical examination and pelvic MRI established a diagnosis of hematometracolpos secondary to uterus didelphys with unilateral imperforate hemivagina. An incision in the vaginal septum allowed drainage of the hematocolpos, providing relief of the patients symptoms. We report two case of uterus didelphys with obstructed hemivagina with brief review of the literature.

After a period of tourism stagnation due to the corona virus epidemic, Korea is preparing to lift self-isolation and PCR results. Accordingly, we designed a platform application that can connect consumers and suppliers of travel guides that can respond to the influx of domestic and foreign tourists. DB design and client design were made using NoSQL-based Firebase server, Android Studio, and Java language. The suggestion app provides location-based tourist recommendation and tourist information output using GPS, and tour guide matching service using user information.

자본시장의 균형과 최적이윤세에 관하여

윤형모 韓獨經商學會 1993 經商論叢 Vol.11 No.-

Die Analyse des Kapitalmarktes zeigt, daβ eine optimale Sparquote[(S/Y)M] existiert, und daβ diese Sparquote die maximale Investitionsquote erzeugt, Deshalbist die Sparquote [(S/Y)M]] ein Ziel der Wachstumspolitik. [(S/f)M] hat den Wert [r (1-R)/l+r]] in der Gleichung (4). Diese Relation besagt, daβ die maximale Invfstitionsquote steigt, wenn der Wert von "r" (Beeinflussung des Konsums auf dir Investitionen groβer wird. Aber das obige Ergebnis muβ modifiziert warden, wunn das wirtschaftspolitische Instrument fur die Korrektur der Sparquote die Einkommensverteilung beeinfluβt. Durch die Senkung der Sparquote kann die Regierung die zweifinanzpolitischen Ziele, Wirtschaftswachstum und Umverteilung zugunsten der Bezieher niedriger Einkommen, gleichzeitig erreichen, wenn die Sparquote groβor als [(S/Y)M] ist Aus dissem Grund muβ die optimale Sparquote[(S/Y)Q], die die finanzpolitischen Ziele von Wirtschaftswachstum und Umverteilung bezuglirh der Wohlfahrt optimal kombiniert, kleiner als [(S/Y)M] sein. Die Gewinnsteuer loβt sich als Instrument fur die Korrektur der Sparquote einsetzen. Mit der Zunahme des Gewinnsteuersatzes sinkt der Nettogewinn und damit die Sparquote, Bei der Ausgabe der Gewinnsteuer steigt die Sparquote nur im kleinen Ausmaβ, wenn die Regierung die Gewinnsteuer fur die Umverteilung zugunsten der Bezieher niedriger Eiukommen benutzt, Denn die Sparquote der Bezieher niedriger Einkommen ist sehr klein. In diesem Fall besteht eine negative Korrelation zwischen den Gewinnsteuersatz und der Sparquote. D. h. die Gewinnsteuer ist als Instrument fur die Herstellung der optimalen Sparquotef[(S/Y)Q] einzusetzen. die Moglichkeit dafur hangt von der Groβe des Existenz-Bereichs fur die Sparquote[(S/Y)Ql ab. Weil 0< [(S/Y)Q]<[(S/Y)M] ist, sinkt der Existenz-Bereich mil der Abnahme des Wertes von [(S/Y)M], der gleich [r(1-R)/(1+r)] in der Gleichung (4) ist. also, wenn der Wert von "r" (Beeinflussung des Konsumsauf die Investitionen) kleiner wird, sinkt der Wert [(S/Y)M] und damit steigt die Moglichkeit, daβ die optimale Gewinnsteuer eingesetzt wird, die Sparquote[(S/Y)Q] herstellt.

The author made a clinical study of 112 inpatients with organic brain syndromes who had been admitted at the neuropsychiatric department of In Je Medical College, Paik Hospital during the past 4 years from Jan. 1975 to Dec. 1978. The results were as follows: 1. The proportion of organic brain syndrome was 12.4% of all hospitalized patients. The sex distribution was 63.4% (N=71) of male and 36.6%(N=41) of female. 2. The most common age was in the twenties. The highest frequency was seen in 40's in male, occupying 17% of all, and 20's in female, 12.5%. 3. The most frequent disease entity was idiopathic epilepsy (30.5%), and followed by brain trauma (15.2%), alcoholic psychosis (14.2%), senile and presenile dementia (8.0%), CO-intoxication (8.0%) and cerebrovascular disorder (7.1%). 4. The acute onset of symptoms (few minutes to several hours) occupied 58.0% of all cases, subactue form (within several days) 9.8%, and chronic form (more than several weeks) 32.1%. 5. Regarding to the clinical course, 55.4% of all cases showed clinical improvement and the rest were sustained, aggravated or resulted in death. 6. According to the diagnostic criteria of DSM-Ⅱ, 42.9% of all cases were found to be psychotic. 7. Among the neurololgical symptoms, the most frequent was convulsion, occupying 37.5% of all, and headache and dizziness (15.2%), incontinence (9.8%) were followed in successive order. On the other hand, acute delirious state was identified in 37.5% of all cases, behavior disorder was seen in 36.6%, and disorientation 26.0%. 8. The cases who were thought to be involved more than two etiological factors in their past history were 10.7%, and 14.3% of all was superimposed with functional mental disorders in the present clinical pictures. 9. Lesser than half (44.6%) of all cases were released from the hospital with the mutual consent between staff and patient. In this clinical study, it was intended to asertain the clinical findings in these patients by comparing with others' reports and to make them available to others for more advanced clinical subgrouping which is essential for specific diagnosis and adequate treatment.

The effect of annealing temperature and holding time on the mechanical properties of pure titanium castings was investigated by means of microhardness test, compression test, microscopic observation, and EDS. Casting process was carried out under argon gas and the heat treatment was carried out under air. The results were as follows : 1. The mechanical properties of the specimens heat-treated at 500, 750℃ were slightly increased, but those of specimen heat-treated at 1,000℃ were remarkably increased by prolonged holding time. 2. The microstructures of specimens heat-treated at 500, 750℃ were bluntly serrated α structure, but that of specimen heat-treated at 1000℃ showed the mixture of acicular α and platelike α structures with a great number of fine precipitates. 4. The surface reaction layer was gradually thinned away by prolonged holding time at 1,000℃, Al and Si elements of the surface reaction layer were homogeneously diffused to the inside of the specimen.

윤형식 외 한국버섯학회 2010 한국버섯학회지 Vol.8 No.3

팽이버섯 병재배에서 재배사 내의 탄산가스 농도를 조절하여 소비자 요구에 맞는 버섯을 안정적으로 생산하고, 생육과 수확에 관련하여 적정기준 설정을 위해 실험을 수행한 결과이다. 공시균주 특성 값을 종합해보면 탄산가스 농도가 높아지면 초발이소요일수, 생육일수, 수확일수는 증가하는 경향이고, 백색계열보다 갈색계열이 탄산가스 농도에 상관없이 초발이소요일수, 생육일수, 수확일수가 전체적으로 짧으며, ASI 4103 균주와 같이 균주의 유전적 형질이 재배적 특성에 많은 영향을 주는 것으로 판단된다. 병당 수량성은 균주에 따라 처리농도에 따른 증감의 차이는 있으나, 전반적으로 탄산가스 농도가 높아지면 수확량은 감소하였다. 개체중은 균주에 따라 약간씩 차이는 있으나 대체적으로 탄산가스 농도가 증가하면서 약간씩 감소하는 경향이다. 병당 개체수에서는 균주간의 차이가 커서 탄산가스 농도 증가에 따른 일정한 경향을 확인 할 수 없었다. 자실체의 수분함량은 균주에 따라 약간의 차이는 있으나 탄산가스 농도의 증가에 따라 수분함량이 감소되었다. This study was performed to determine the optimal concentration of carbon dioxide, which effects mushroom growth and yield. It was shown that the periods for fruiting initiation, growth and harvest of Flammulina velutipes were increased when the CO₂ concentration was raised. In general, those characteristics were less affected in brown strains than in white ones. Especially brown strain ASI4103 was susceptible to changes in CO₂ concentration. Yields per bottle and individual mushroom weight also decreased in most strains when CO₂ levels increased. We were unable to designate any tendency in the number of fruiting bodies due to the large variation within each respective strain. Finally, water contents in the fruiting bodies were found to decline under high CO₂ concentrations.

이형복,정윤중,김진규 明知大學校 産業技術硏究所 1988 産業技術硏究所論文集 Vol.7 No.-

The crystal phase of 1000℃ calcined powder, which was coprecipitated from the mixed solution of ZrOCl₂-8H₂O and CaCl₂- 2H₂O was detected by the DTA, XRD and SEM. At that time the mixed solution was varied with ZrO₂/CaO mole ratio, i.e. ZrO₂/CaO=0.7/0.3, ZrO₂/CaO=1/1 and ZrO₂/CaO=0.3/0.7. And also the pH value was controlled with NH₄OH solution as 2,4,6,8,10 and 12, respectively. Each system had the behavior of the formation of monoclinic ZrO₂ with tile lower pH value. The former two system showed the formation orthorhombic CaZrO₃ when the pH was 10 and 12. But at the system ZrO₂/CaO=0.3/0.7, the little amount of cubic ZrO₂ crystal phase was detected to coexist with the orthorhombic CaZrO₃ at pH 12.

Purpose: Because studies about the control of penile erection at the entral nervous system was dependent on the animal experiments, establishment of measuring penile erection is important to evaluate the effects changes at the central nervous system on the penile erection. Intracavernous pressure measurement in rats has been introduced as a suitable index for the evaluation of penile erection but this method is invasive and technically difficult. So, we established the intracavernous pressure measurement in rats as the experimental index for penile erection. Materials and Methods: 42 male adult Sprague-Dawley rats (250-300gm) were divided to saline or papaverine treated group. Rats were placed on a heating table to maintain their body temparature and anesthetized with 50mg/kg of pentobarbital sodium by intraperitoneal injection. A cannula was inserted to the left carotid artery to measure systemic blood pressure. Saline (0.05, 0.1ml), papaverine(0.05, 0.1, 0.25, 0.5, 1.0, 2.0mg) were injected intracavernously via 26 guage needle filled with saline or papaverine which connected to pressure transducer and polygraph was inserted into the corpus cavernosum on one side to inject the drug and to measure intracavernous presure. Results: Properly executed insertion and intracavernous administration produced a instantaneous but transient rise in intracavernous pressure that substantially stabilized and maintained at 5.4±0.4mmHg. Intracavernous pressure and duration of penile blood flow following intracavernous injection of papaverine are increased comared to those of saline. Conclusions: Monitoring intracavernous pressure in rats represents a suitable index for the evaluation of penile erection in small laboratory animals.

Clinically, proximal bone resorption in the femur is frequently seen postoperatively on the follow up X-rays after total hip replacement (THR). The stress shielding on the medial proximal region of femoral bone is known as a main cause of the resorption phenomina. In order to understand the mechanism of stress shielding and bone resorption, stress analysis is performed by finite element method. We developed two and three dimensional finite element model of cementless THR. The two dimensional model is proposed with side plate element, whereby the three dimensional structural integrity of the bone can be accounted for. Thereby, the complex geometry of femoral bone and artificial stem can be simplified. The three dimensional analysis is also performed for more universal validity. The subject of this article is the development and application of this two an three dimensional finite element models to study the stress shielding phenomina on femur after THR. The results of this study indicates that stress distributions from finite element analysis of two and three dimensional models well explain the stress shielding phenomina.
