We studied two papers that are written by each-team and compared to integrate into single study to improve the educational effectiveness. In the course of studying individual result together, we found that one of them is on the active motion, and the other is on the static motion. This idea led us to a study on a implementation of home entrance control system using infrared sensors and load cells. This research approach will broaden the study and present a diversification on the study.

Pancreatic arteriovenous malformations (AVMs) are rare, and most cases occur as congenital anomalies. Many patients with AVM are asymptomatic, but occasionally present with abdominal pain or gastrointestinal bleeding. The increased portal vein flow that forms these malformations can lead to portal hypertension and gastrointestinal bleeding in the absence of primary liver pathology. Early diagnosis can lead to successful surgical resection or percutaneous transarterial embolization. We report a case of a patient with pancreatic AVM in the tail of the pancreas, in which endoscopic ultrasonography was helpful. This patient presented with abdominal pain and was subsequently treated with distal pancreatectomy. (Korean J Med 2013; 84:708-712)

Objective: To evaluate the potential effect of uterine weight on short-term outcome and incidence of complications after total laparoscopic hysterectomy (TLH) for a benign gynecologic disease. Methods: A retrospective medical record review of 771 cases where TLH was performed. Patients included in this study underwent TLH for either myoma or adenomyosis at Gil Hospital, Gachon University of Medicine and Science, from March 2006 through December 2010. Participating patients were stratified into three groups: group 1 with uterine weight less than 250 g (n=435), group 2 with uterine weight 250 to 500 g (n=272), and group 3 with uterine weight more than 500 g (n=64). The groups were compared based on total operation time, estimated blood loss, length of postoperative hospital stay, observations of postoperative complications, and rate of conversion from to TLH to laparotomy. Results: We discovered no statistical difference between the three groups in terms of overall postoperative complications or short-term surgical outcomes. Major complications such as ureter injury and necessity for reoperation occurred in each group. Operation time and estimated blood loss increased slightly as uterine weight increased, but, there was no statistical significance. Conclusion: TLH can be successfully performed, even in cases of enlarged uterus. Patients with an enlarged uterus are suitable candidates for TLH.

This study was performed to determine if women with day 3 serum inhibin-B concentrations <45pg/ml (conversion factor to SI unit, 1.00) demonstrate a poor response to ovulation induction and assisted reproductive technology outcome to women with inhibin-B${\ge}45pg$/ml, independant of day 3 FSH, E2 and patient age. From Jan 1996 to Dec 1996, 16 volunteers patients who underwent 25 IVF cycles with luteal phase GnRH agonist suppression and HMG stimulation were allocated to the study group. We evaluated day 3 serum inhibin-B, FSH, E2, peak E2, cancellation rate per initiated cycle (%) and clinical pregnancy rate per initiated cycle (%) according to the above two groups and independent of patient age, day 3 FSH, day 3 E2 and all of above combined. Women with day 3 serum inhibin-B${\ge}45pg$/ml demonstrated higher average day 3 inhibin-B level, clinical pregnancy rate per initiated cycle ($20.3{\pm}2.5$ pg/ml vs $80.9{\pm}5.0$ pg/ml, p<0.05; 24.8% vs 8.5%, p<0.05) and lower day 3 FSH level, cancellation rate per initiated cycle ($6.9{\pm}0.3$ mIU/ml vs $8.5{\pm}0.5$ mIU/ml, p<0.05; 1.5% vs 9.0%, p<0.05). Women with day 3 serum inhibin${\ge}45pg$/ml and age<40 year demonstrated higher pregnancy rate per initiated cycle (28.2% vs 7.4%, p<0.05) and lows. day 3 FSH level, cancellation rate per initiated cycle ($6.9{\pm}0.5$ mIU/ml vs $8.2{\pm}0.7$ mIU/ml, p<0.05; 1.0% vs 9.0%, p<0.05). Women with day 3 serum inhibin${\ge}45pg$/ml and day 3 FSH<15mIU/ml demonstrated higher pregnancy rate per initiated cycle (33.5% vs 9.5%, p<0.05) and lower day 3 FSH level, cancellation rate per initiated cycle ($7.7{\pm}0.2$ mIU/ml vs $8.5{\pm}0.5$ mIU/ml, p<0.05; 1.5% vs 10.0%, p<0.05). Women with day 3 serum inhibin${\ge}45pg$/ml and day 3 E2<50pg/ml demonstrated higher pregnancy rate per initiated cycle (30.0% vs 9.5%, p<0.05) and lower cancellation rate per initiated cycle (1.5% vs 9.5%, p<0.05). Women with day 3 serum inhibin${\ge}45pg$/ml, age<40 year, day 3 FSH<15mIU/ml and day 3 E2<50pg/ml demonstrated higher pregnancy rate per initiated cycle (30.0% vs 10.8%, p<0.05) and lower day 3 FSH level, cancellation rate per initiated cycle ($6.8{\pm}0.6$ mIU/ml vs $8.4{\pm}0.9$ mIU/ml, p<0.05; 1.5% vs 7.8%, p<0.05). Therefore women with low day 3 serum inhibin-B concentrations demonstrate a poorer response to ovulation induction and are less likely to conceive a clinical pregnancy though ART relative to women with high day 3 inhibin-B and day 3 serum inhibin-B, in addition to a day 3 FSH, E2 and patient age, appears helpful in prediction in IVF-ET outcome.

Impetigo herpetiformis is a rare disease, which traditionally has been classified among the unique dermatoses of pregnancy. It is associated· with severe maternal and fetal complications in case of misdiagnosis and delayed treatment. Diagnosis is based on the overall clinical, laboratory, and histological features. Promt and aggressive treatment is needed, and termination was effective in severe case. This pregnant woman was 32-years-old multigravida with transverse lie of fetus. At 24 weeks gestation, she developed erythematous scaly annular patchs with papules and pustules on inner thigh. The skin lesion was aggravated at 31 gestational weeks. The skin of the affected area was biopsied and the result was consisitent with impetigo herpetiformis. Treatment commenced with intravenous fluids, intravenous dexamethasone under the careful fetal well being monitoring. Cesarean section was done due to transverse lie of fetus, and a normal healthy baby was delivered, following which the patient condition improved rapidly. At one month after the delivery, the skin lesions of the patient was fully recovered.

The mechanism of apoptosis was first discovered at the end of the 19th century, but it was only recently that its importance was recognized. Not only in a pathologic environment but also in a normal environment, apoptosis has an important role in homeostasis. The number of cells is restricted by apoptosis which is controlled by several SlgBS lll VlVO. In pregnancy, the placenta regulates the maternal-fetal exchange of molecules and functions as a barrier for the protection of the fetus. As the pregnancy proceeds, changes occur in the number and components of placental cells. Observing the placental tissues, apoptosis was found in the syncytiotrophoblasts of early and late pregnancy. In particular, the fact that apoptosis observed in the placenta of late pregnancy supports the hypothesis that pmgrammed cell death is a normal sequence. Pregnancy-induced hypertension is usually accompanied by abnormal placenta and intrauterine growth restriction. In this study, using the TdT-FragEL DNA fragmentation detection kit, the changes in the nucleus by apoptosis in the placental tissues of 23 to 40 gestational weeks in preeclampsia and eclampsia were compared with normal placenta. Apoptosis was observed in the normal term placenta and in pregnancy-induced hypertension patients, regardless of whether vasculopathy was observed in Doppler ultrasound or confirmed by pathology, more apoptoses were observed aside from the number of gestational weeks.

SINE-R retroposons, derived from the human endogenous retrovirus HERV-K family, have been found to be hominoid-specific. Both SINE-R retroposons and HERV-K family have potential relevance to recent genome change and various human diseases. In this report, we identified seven SINE-R retroposons from the human brain cDNA library and compared them with sequences that we have previously reported in humans and hominoid primates. The SINE-R retroposons derived from human brain cDNA library showed 91∼95% sequence similarities with human-specific retroposon SINE-R.C2. They also showed 88∼92 % sequence similarities with that of the Schizo-cDNA clone that derived from postmortem tissue from the frontal cortex of & individual suffering from schizophrenia who committed suicide at the age of thirty-four. Phylogenetic analysis using the neighbor-joining method revealed that three SINE-R retroposons (HB-4, HB-5, HB-7) from the human brain cDNA library were closely related to the human-specific retroposon SINE-R.C2. The data indicate that such retroposons transcribed in the human brain represent a source of genetic variation related to neuropsychiatric diseases.

Purpose: The purpose of this study is to understand a variety of intervention studies to prevent smoking by adolescents in U.S. and find out implications for Korea Methods: This study reviewed articles found in the internet and analysed the data of US DHHS and CDC. Results: The School Health Policies and Programs Study (SHPPS) is a national survey periodically conducted to assess school health policies and programs of U.S. The main components of SHPPS are health education and physical education health services, mental health and social services school policies and school environments The CDC guidelines for school health programs to prevent tobacco use and addiction are composed of policy instruction curriculum, training family involvement tobacco-use cessation efforts and evaluation School-based interventions to prevent smoking can be classified into the categories of information-giving curricula, social competence curricula social influence approaches combined methods draw on social competence and social influence approaches and multi-modal programmes and Youth Empowerment study The key programs for adolescent smoking prevention an; ALERT Project, HSPP, TNT Project MPP NC YES. Conclusions: As smoking is often the first step of unhealthy behaviour such as alcohol drinking illegal drugs and violence, smoking prevention programmes for adolescents in U.S. have been comprehensive school-based health programs. In smoking prevention programs for adolescents CDC plays a critical role by supporting survey, research policy and funds. The effectiveness of the programs was high when it was based on school and involved parents community and mass media As the effect of each programme is not expected to last for a long time consistent repetition of these interventions is essential Current smoking prevention programs for adolescents are exploring the empowerment approach focused on the active involvement of participants rather than traditional approaches using order and discipline.

Molecular Cloning of HERV-W LTR Family from Human Brain

Kim, Heui-Soo,Yi, Joo-Mi,Kim, Tae-Hyeong,Lee, Ji-Won,Kim, Myung-Sook 한국유전학회 2002 Genes & Genomics Vol.24 No.2

Long terminal repeat (LTR) elements of the human endogenous retrovirus (HERV) have been found to be coexpressed with sequences of genes closely located. It has been suggested that the LTR elements have contributed to the structural change or genetic variation of human genome connected to various diseases and evolution. The HERV-W family has been identified in the cerebrospinal fluids and brains of individuals with schizophrenia. Using cDNA library derived from human brain tissue, we performed PCR amplification and identified five new HERV-W LTR elements. Those LTR elements showed a high degree of sequence similarity (96∼99%) with the HERV-W LTR (AF072500). A phylogenetic tree obtained by the neighbor joining method revealed that new HERV-W LTR elements (HB-1 and HB-3) were closely related to the HERV-W LTR family, AX000960, AF072504, and AF072506, from GenBank database including the HERV-W LTR. Compared to the HERV-W LTR elements, clones HB-11, HB-12, and HR-15 had additional sequences (CTGTTTGCCA CCACCA) specifically. The data indicate that several copy numbers of the HERV-W LTR elements are transcribed in human brain and may contribute to an understanding of brain function in relation to neuropsychiatric diseases.
