We report the case of a 14-year-old girl who visited the emergency room because of suprapubic discomfort and sudden acute urinary retention. She did not have any significant medical and surgical history, and her neurological examinations were all normal. Urinary catheterization led to the passage of 500 mL urine. Abdominal ultrasonography showed a hematocolpos that was compressing the urinary bladder. Gynecologic history taking revealed that the patient has not had menarche yet. Therefore, a cruciate incision was performed and her urination became normal. As the surgical outcome after adequate hymenotomy for imperforate hymen is usually good, the diagnosis of imperforate hymen is important. However, this condition is easily missed in the clinic because the first physician visited by the patient rarely takes a detailed gynecologic history or performs appropriate physical examinations. Although rare, imperforate hymen should be considered as a cause of acute urinary retention in the adolescence period. If an adolescent girl presents with abdominal pain and voiding dysfunction, a detailed gynecologic history and appropriate physical examinations of the genital introitus should be performed.

A practical and convenient method of rearing Eucyclops serrulatus in a microculture environment is described. A complete life cycle of E. serrulatus was maintained in a narrow space on a microscope slide glass on which a cover glass of $22{\times}40mm$ in size was mounted at a height of 0.8mm. The culture medium was constituted by bottled mineral water boiled with grains of Glycine max (soybean). Chilomonas paramecium, a free-living protozoan organism, was provided as live food. Growth of nauplii hatched from eggs to the first stage of copepodite took an average of 7.7 days, and the growth of copepodite 1 to the egg-bearing adult female took an average of 20.1 days in the microculture cell with an average life time of 44.7 days. Continuous passage of cope pods was successfully maintained as long as sufficient medium and food were provided. The microculture method enables an in situ microscopic observation on the growth and developmental process of helminth larvae experimentally infected to copepods as well as of copepod itself. Furthermore, it does not require anesthetization and, therefore, minimize the amount of stress exposed to cope pods during the handling process.

Carboplatin intra-arterial chemotherapy(IAC) has an advantage of increased uptake during the first passage of the drugs through tumor capillaries. Although not common, this type of therapy is known to cause neurological complications, myelosuppression, and ototoxicity. However, the incidence of ocular toxicity is reported to be rare. Eleven of our patients with glioma(Grade II Astrocytoma : 3, Grade III Astrocytoma : 1, Grade IV Astrocytoma : 5, Gliofibroma : 1, Oligodendroglioma : 1) underwent IAC regimen with carboplatin($300mg/m^2$) which were administrated after blood-brain barrier disruption. Of there, 3 patients had ocular complications after supra-ophthalmic IAC injection of carboplatin but fully recovered following steroid therapy. Although our results from IAC seem to be favorable for these patients, we suggest that its complications, such as ocular toxicity, need to be carefully considered prior to treatment.

Meconium ileus (MI) is the earliest clinical manifestation of cystic fibrosis (CF) in infants. It arises from the intraluminal accumulation of highly viscid, protein-rich meconium, typically present in the terminal ileum as a neonatal intestinal obstruction. Therefore, the clinical symptoms include abdominal distension, bilious vomiting and delayed passage of meconium. CF is caused by mutations in the transmembrane conductance regulator gene (CFTR) located in the long arm of chromosome 7. CF is common in Caucacians, but is a rare disorder in Asian countries, including Korea. We experienced a case of CF combined with MI. Compared with the previous reports of CF in Korea which presented respiratory problems, this is the first case genetically diagnosed as CF with MI during the newborn period.

This paper presents the numerical simulation results of heat transfer and friction loss for a rotating two-pass duct with the airfoil-guide vanes in the turning region. The Kriging model is used as an optimization technique with Reynolds-averaged Navier-Stokes analysis of flow field and heat transfer with shear stress transport turbulent model. To improve the heat transfer performance, angle and location of the airfoil-guide vanes have been selected as design variables. The optimization problem has been defined as a minimization of the objective function, which is defined as a linear combination of heat transfer related term and friction loss related term with a weight factor. The airfoil-guide vanes in the turning region keep the high level of heat transfer while the friction loss has a low value. By comparing the presence or absence of airfoil-guide vanes, it is shown that the airfoil-guide vanes exhibited the best heat transfer performance to improve the blade cooling except the first passage.

본 연구는 osteoblastic cells에서 estogen 의 생합성을 유도하는 aromatase의 activity에 대한 봉독(蜂毒)작용을 측정하여, 봉독치료시 Arthritis의 진행 억제 및 estogen의 의한 bone formation의 효과여부를 검증하기 위해 실행하였다. 사용된 세포주로는 Osteoblastic phenotype으로 분화가 유도되는 Human leukaemic cell line FLG 29.1 및 the primary first-passage osteoblastic cells (hOB cells)이며, 이들을 각각 배양하고 각각의 RNA를 isolation한 뒤 PCR 증폭을 하였다. Aromatase에 대한 활성인자인 TPA와 TGF-${\beta}1$ 및 봉독을 이용하여 aromatase의 expression 및 activity에 대해 미치는 영향을 측정한 바, aromatase expression은 FLG 29.1 cell와 hoB cells에서, 50nM TPA 24시간 처리, 봉독 2 ~ 4시간 처리와 TGF-${\beta}1$ 3시간 처리로 유도한 결과 TPA와 TGF-${\beta}1$의 경우는 서로 유사하였고, 봉독에서 상대적으로 높게 나타났다. Aromatase activity는 FLG 29.1 cell, hoB cells에서 24시간 incubation한 결과, 모든 실험에서 일정하게 선상증가를 보였다. $5{\mu}{\ell}/m{\ell}$ BV에서 TPA와 TGF-${\beta}1$보다 뚜렷하게 증가하였으며, 0.5mM Bt2-cAMP, 50nM dexametasone처리에서는 유의성이 없었다. Estrogen 생합성을 촉매하는 aromatase activity BV가 처리에서 현저하게 증가하였기에, Rheumatis arthritis의 bone destruction에 대해 BV가 효과적인 역할을 할 것으로 보여진다.

In connection with a non-cash payment through the banking system, "finality of payment" has acquired diverse meanings. In according to Section 4A-209(2), the acceptance by the beneficiary's bank by means of receiving payment "pursuant to section 4A-403(a)(1) or 4A-403(a)(2)," constitutes final settlement through a Federal Reserve Bank or through a funds-transfer system" or credit to the account of the beneficiary's bank. Above of all, Acceptance by beneficiary's bank is the most important. According to 4A-209(b), the beneficiary's bank can accept a payment order in one of four ways : First, by paying the beneficiary; obligating itself to pay the beneficiary or, Second, by notifying the beneficiary of receipt of the order or notifying the beneficiary that its account was credited or, Thirdly, by receiving full payment from the sender's order or Lastly, by passage of time, i.e., the opening of the next funds transfer business day of the bank following the payment date of the order. A beneficiary's bank is considered to have accepted a payment order when the earliest of the four means of acceptance occurs.

The experimental study investigates two aspects of counterflow sensible heat regenerator operation. First, it examines the regenerator performance in periodic steady state operation with spatially nonuniform inlet temperature in one of the fluid stream. Second, the study examines the transient response of a regenerator to a step change in the inlet temperature of one of the fluid streams. The effect of transient inlet temperatures is analyzed in terms of the response of the outlet fluid temperatures to a step change in temperature of one of the inlet fluid streams. The effect of temperature nonuniformities is analyzed in terms of the change of temperature nonuniformities is analyzed in terms of the change in steady state effectiveness due to a circumferential temperature distribution in one of the inlet fluid streams. an experimental analysis has been conducted using a counterflow, parallel passage, and rotary regenerator made from polyethylene film. Efficiencies follow similar trends with increasing matrix to fluid capacity rate ratio for the balanced and symmetric regenerator with nonuniform inlet temperature.
