The purpose of this study is to examine the effect of transportation accessibility on the performance of convention centers in Korea with quantitative measures. The transportation system for this study are classified by 3 different methods in terms of high-speed railway, airline, and bus. The panel data were gathered from the each convention center’s financial statement from 2005 to 2019 provided by DART or the convention center’s web site, as well as the distance and travel time data were collected from the NAVER portal service. The dependent variable used in this study is the revenue of convention center and the independent variables are the distance and travel time between each transportation facility and convention center. Control variables are total asset, current ratio, net profit margin, non-current asset turnover, tourism crisis dummy variable. This study was conducted to utilize the panel data analysis by using the random effect model through STATA program. The empirical results show that the distance and travel time between the convention center and transportation facilities had a negative effect on the revenue of the convention center. In other words, the higher accessibility from transportation, the more positive effect will occur on the revenue of the convention center. In addition, total asset, net profit margin, and non-current asset turnover have a positive effect on the revenue of convention center. Therefore, the accessibility from the transportation to convention center would be considered as an important factor to increase the performance of convention centers in Korea.

목적 : 산전 유전 및 염색체 질환을 진단할 수 있는 융모막 검사에는 경자궁경부방법과 경복식방법이 있다. 본 연구에서는 두 방법의 융모막 검사 중 보다 안전하고 효율적인 방법을 알아보고자 실시하였다. 연구방법 : 본 연구에서는 1991년 1월에서 1998년 6월까지 전북대학교병원 산부인과에서 산전진단의 적응증에 해당하는 788명의 임신여성 중 의무기록지 분석이 가능한 633명의 여성을 대상으로 하였고 이중 490명은 경자궁경부 융모막 검사를 143명은 경복식 융모막검사를 실시받았다. 임신 손실은 재태 28주까지로 정의하였고 임신 예후는 후향적으로 의무기록지를 분석하였다. 전 대상 환자는 동일 시술자가 재태 9~12주 사이에 시술하였으며 두 방법의 융모막 검사 중 보다 안전하고 효율적인 방법을 알고자 임신손실율, 일차 시술성공율, 합병증 등을 비교 하였다. 결과 : 표본 채취 기구의 1회 삽입 후 표본을 얻는데 경자궁경부 방법에서는 88%, 경복식 방법에서는 94.4%의 성공률을 보였다(P<0.05). 시술 후 염색체 검사상 정상이면서 임신 28주까지의 태아손실율은 경자궁경부방법이 경복식방법보다 높았다(4.9%, 3.5%). 시술 후 합병증으로는 융모막하혈종, 양수유출, 질출혈, 융모양막염등이 나타났고, 그 빈도는 경자궁방법이 경복식보다 높았다(3.9%, 2.8%). 결론 : 임신 제 1기에 유전 및 염색체 질환을 진단하는데 경복식 융모막 검사가 경자궁경부방법에 비해 시술이 용이하고 동등한 안전성을 갖는 검사로써 향후 널리 시술될 수 있으리라 생각된다. Objectives : Our purpose was to compare the safety and efficacy of transcervical and transabdominal chorionic villus sampling.Methods : From January 1991 through June 1998, we retrospectively compared transcervical and transabdominal chorionic villus sampling in 633 women. Both CVS procedures were performed between 9 and 12 weeks of gestation by single operator. Both groups were followed to determine the outcome of pregnancy and the rate of spontaneous fetal loss after chorionic villus sampling.Result : Sampling was successful after a single insertion of the sampling instrument in 94.4 percent of the transabdominal procedures and 88 percent of the transcervical procedures(p〈0.05). Among the women with chromosomally normal pregnancies, the rate of spontaneous fetal loss through 28 weeks of pregnancy was 4.9 percent in the transcervical-sampling group and 3.5 percent in the transabdominal-sampling group. The frequency of symptoms and complication after transcervical procedures was slightly higher than transabdominal procedures (3.9%, 2.8%).Conclusion : Transabdominal and transcervical chorionic villus sampling appear to be equally safe procedures for first-trimester diagnosis of fetal abnormalities.

The purpose of this research is to approach and understand school adjustment of adolescents multi-dimensionally and integratively. This study also investigates the structural relationship between school adjustment of adolescents and variables including poverty level, perceived parental rearing attitude, learning motivation, and psychological well-being, all of which are expected to influence school adjustment of adolescents. To achieve the objectives, the results of the study were investigated as follows. First, what is the structural relationship among poverty level, perceived parental rearing attitude, learning motivation and psychological well-being, and school adjustment? Second, do poverty level, perceived parental rearing attitude, learning motivation and psychological well-being have an impact on school adjustment? A total of 1303 students including 564 boys and girls in the second and third grades of three middle schools, and 739 boys and girls in the first and second grades of four high schools located in Daegu were studied for this research. First of all, tests of perceived parental rearing attitude, learning motivation, psychological well-being, and school adjustment were conducted. Then, based on the minimum cost of living released by the Ministry of Health and Welfare, students from poverty level and non-poverty level families were divided. The results of the study are as follows. First, it was revealed that there were passive correlations among variables after analyzing correlations among perceived parental rearing attitude, learning motivation, psychological well-being, and school adjustment. Specifically, poverty level influenced perceived parental rearing attitude and learning motivation indirectly, and it had an impact on school adjustment through perceived parental rearing attitude and learning motivation. Perceived parental rearing attitude affected school adjustment through learning motivation and psychological well-being, and learning motivation and psychological well-being had a direct effect on school adjustment. Second, this study shows that learning motivation and psychological well-being have a direct and indirect impact on school adjustment, and both poverty level and perceived parental rearing attitude influenced school adjustment indirectly. Through the results of verifying the indirect impact of perceived parental rearing attitude, learning motivation and psychological well-being on school adjustment, it is revealed that these variables have statistically meaningful meditation effects. Therefore, it is shown that poverty level, perceived parental rearing attitude, learning motivation, and psychological well-being have a significant impact on school adjustment.

Objectives : In this study, we tried to analyze the relationship between effect terms and five tastes in heat-clearing herbs. In order to analyze exactly, we also attempted to extract and refine the effect terms. And finally, we tried to infer the effects of each tastes and suppose new effects of each heat-clearing herbs based on their tastes. Methods : Firstly, we extracted the five tastes and effect terms among the heat-claearing herbs written in Herbology. After that, we divided each effect terms to single meaning term and refined them. We also grouped herbs by tastes and set the effect terms in the order of frequency. So we could analyze the relationship between the tastes and the effect terms and supposed the effect of each herbs. Results & Conclusions : We extracted 7 tastes and 87 effect terms. And they was refined to 63 effect terms. As the result of analyzing the effect terms based the tastes, all of heat-clearing herbs included the effects of heat-clearing and detoxification, regardless of tastes. The herbs which have the bitter tastes, included the effects of drying dampness, fire-purging and blood-cooling. And we supposed new effects in 10 kinds of herbs among them. The herbs which have the sweet tastes, included the effects of blood-cooling and fluid-engendering. The herbs which have the hot tastes, included the effects of inducing diuresis and swelling-dispersing. And we supposed new effects in 2 kinds of herbs, by analyzing the relationship between the tastes and effect terms.

Cryopreservation is able to store the surplus pre-embryos for freezing and furthermore thawing and transfer in a subsequent cycle. Cryopreserving cells which are maintaining their viability are the very complex process. This study has been carried out in order to find the effects of cryopreservation steps, freezing media and embryonic stages on the rates of viability and development of cryopreserved mouse embryos. Female ICR mice ($6{\sim}8$ weeks old) were induced to superovulate by sequential intraperitoneal injection of 5 IU PMSG and 5 IU hCG 48h apart. Mouse embryos were collected according to its developmental stage after the injection of hCG. Embryos were cryopreserved not only by cryoprotectant step (1 step${\sim}$4 step) but also in a variety of media (HTF, IVF medium, D-PBS) and cell stage. The results were as follows: There is no clear advantage in these freezing media of rapid method, but 4 cell and 8 cell of slow method (2, 3, 4 step) have advantage in D-PBS. The development of embryos according to cell stage become greater in 8 cell stage. In the treatment steps of cryopreservation, the development of embryo to blastocyst was similar among rapid method, but the development of 4 cell and 8 cell embryos to blastocyst according to slow method was better than rapid method.
