Objective: To determine whether the somatostain analogue, octreotide, pretreatment before ovulation induction with human menopausal gonadotropin (hMG) affects ovarian response, and ovulation induction outcome in infertile patients with polycystic ovarian syndrome (PCOS) resistant to clomiphene citrate (CC) Methods: From November 1998 to June 1999, 30 infertile patients with PCOS unresponsive to CC were randomly allocated either octreotide pretreatment (treatment group) (n = 15) or hMG alone (control group) (n = 15) groups. In the treatment group, 100 g of octreotide were administered daily for 7 days after progesterone injection for withdrawal bleeding, and then hMG was administered for ovulation induction. Results: There were no differences in the total number of hMG ampules required and the duration of hMG administration between the two groups. The number of follicles of 10-14 mm diameter on the day of hCG injection was significantly less in the treatment group than that in the control group (4.3 ± 2.5 vs. 9.6 ± 4.4, p < 0.001). The serum estradiol (E2) level on the day of hCG injection was significantly lower in the treatment group, with 1579.2 ± 421.0 pg/ml compared with 2120.3 ± 512.7 pg/ml in the control group (p < 0.001). The hematocrit level on the day of hCG injection was also significantly lower in the treatment group than that in the control group (36.9 ± 2.1% vs. 40.8 ± 2.9%, p < 0.05). The incidence of severe ovarian hyperstimulation syndrome (OHSS) seemed to be lower in the treatment group, but the difference did not achieve significance (6.7% vs 20.0%). Conclusion: This study suggests that octreotide pretreatment before ovulation induction could improve hormonal milieu compared to hMG alone, and therefore may be effective in ovulation induction for patients with PCOS resistant to CC.

The automatic welding systems, have received much attention in recent years, because they are highly suitable not only to increase the quality and productivity, but also to decrease manufacturing time and cost for a given product. Automatic welding work in semiconductor or space industry to be carried out in pipe line and butt joint mostly and plasma arc welding(PAW) is actively applied. To get the desired quality welds in automated welding system is challenging, a mathematical model is needed that has complete control over the relevant process parameters in order to obtain the required mechanical properties. However, In various industries the welding process mathematical model is not fully formulated for the process parameter and on the welding conditions, therefore only partial variables can be predicted. Therefore, this paper investigates the interaction between the welding parameters and mechanical properties for predicting the weld bead geometry by analyzing the S/N ratio.

Tandem arc welding is a guarantor for high efficiency and cost saving since the quantity of wire which is deposited in the welding is approximated 30% greater that in conventional welding. The welding process is now being successfully applied in many industries. However, in the case of tandem arc welding, good quality and high productivity should depend on the welding parameters. Therefore, an intelligent algorithms for the automatic tandem arc welding process has been necessarily required. In this study, a predictive model based on the neural network by using the data acquired during tandem gas metal arc (GMA) welding process has been developed. To verify the reliability of the developed predictive model, a mutual comparison with the surface of the top-bead width obtained from actual experiments has been analyzed.

Vitamin A palmitate, an oily drug which has low chemical stability and is poorly absorbed in the intestine, was formulated into a novel powdered dosage form. This is designated as a redispersible dry emulsion by freeze-drying technique. Before preparing a dry emulsion, vitamin A palmitate oil in solid in water (O/S/W) emulsion with soybean oil and coconut oil using Aerosil 200 as an emulsion stabilizer and polyoxyethylene-polyoxypropylene-blockcopolymer (Pluronic F68) as a surfactant was prepared. The resultants of the stability tests indicated that vitamin A palmitate O/S/W emulsion was improved on increasing the oil content of the formulation. The resultant dry emulsion particles have a good stabilities and free flow properties and readily released the oily droplets to form stable emulsions on rehydration. The drug releasing property from the resultant dry emulsion particles was dependent on factors such as amount of oily carrier(soybean oil) and surfactant(Pluronic F68) formulated. Above 80% of vitamin A palmitate content was released from the dry emulsion for 1 hour. It was deduced that vitamin A palmitate dry emulsion was definitely suitable for oral administration, since small droplets of vitamine A palmitate from the dry emulsion may alter the drug absorption profile resulting in bioavailability enhancement.
아동이 지각한 부·모 과보호가 아동의 내현적 자기애에 미치는 영향에서 교사지지의 조절효과

본 연구에서는 아동이 지각한 부·모 과보호가 아동의 내현적 자기애에 미치는 영향에서 교사지지의 조절효과를 검증하였다. 이를 위해, 전라북도 N시에 소재한 초등학교에 재학 중인 4·5·6학년 280명을 대상으로 아동이 지각한 부·모 과보호, 아동의 내현적 자기애, 교사지지 척도를 사용하였다. 수집된 자료는 SPSS 25.0 프로그램을 이용하여 내적합치도, 독립표본 t-검정, ANOVA, Pearson의 상관분석, 위계적 중다회귀분석을 실시하였다. 연구결과는 다음과 같다. 첫째, 남아가 여아보다 부모의 과보호를 높게 지각하는 것으로 나타났다. 둘째, 부모가 과보호를 할수록 자녀의 내현적 자기애는 높아지는 것으로 나타났다. 그러나 교사가 정서적 지지와 실용적 지지를 많이 할수록 아동의 내현적 자기애의 특성이 낮아지는 것으로 나타났다. 셋째, 교사지지는 부의 과보호가 아동의 내현적 자기애에 미치는 영향에서 조절효과가 있는 것으로 나타났다. 그러나 교사지지는 모의 과보호가 아동의 내현적 자기애에 미치는 영향에서는 조절효과가 나타나지 않았는데 교사지지 보다 모의 과보호가 아동의 내현적 자기애를 더욱 강력하게 예측한다. 이는 학교에서 교사가 아동에게 미치는 영향력의 중요성을 제고하고, 발달적으로 독립해야 하는 초등학교 고학년시기이지만 여전히 어머니라는 존재는 아동에게 아버지나 교사보다 상대적으로 더 많은 영향력을 미치고 있다는 것을 의미한다. The purpose of this study was to investigate the moderating effects of teacher support between children’s perception of parental overprotection and children’s covert narcissism. The sample consist of 280 children in 4th, 5th, and 6th grades of elementary school from N city, Jeonbuk, Korea. The collected data were analyzed using descriptive statistics, Cronbach’α, t-test, ANOVA, Pearson’s correlation analysis, hierarchical multiple regression analysis using SPSS 25.0 program. The results of this study can be summarized as follows: First, it can be seen that boys are perceived as being more protective of their parents than girls. Second, the more the parents are overprotective, higher the chances that their children will reveal covert narcissism. Unlike parents, the more the emotional and practical support teachers provide, the lower the chances of covert narcissism being displayed by the children. Third, teacher support was found to have a moderating effects upon the father’s overprotection and this in turn impacted on children’s covert narcissism. However, this did not seem to affect the mother. This suggests that teacher support decreased the children’s covert narcissism, however a mother’s overprotection is more predictive of children’s covert narcissism. It can be thus inferred that whilst teachers are required to increase the importance of their influence on children and to become independent in development, the existence of a mother still has relatively more influence on children than either fathers or teachers.

This study is to produce web site with 3D animation through GUI(Graphical User Interface). In the virtual space, consumer have potential power of buying with web surfing in the internet, therefore it is necessary to consider the personal interest and taste of interface. So it can constructed the virtual space with the combining technologies of 3D animation, Fash, and VRML. Consumer can walk-through in this space with familiarity and reality. To compress file and application technology of 3D animation in web design, it will establish Mixed Mall which is a next version of shopping mall.
