Although various values should be expressed in an exhibition space, it is subject to realistic limits of a general space. To express those values easier and more diversely, this research would like to suggest an exhibition based on augmented reality technologies. In addition, among many studies related to augmented reality, only few of them include user evaluation. Therefore, this research would like to explore the notion of augmented reality, major technologies that realize exhibitions, and effective measures to create an exhibition which maximize the immersion of the audience. With the analysis on preceded research, this research drew out user evaluation factors and discovered the measures to realize exhibitions in permanent exhibition spaces based on augmented reality. The measures of realizing augmented reality exhibitions include marker and pattern, display, and 3D model and the user evaluation factors include exhibition satisfaction, presence (existence, immersion), and interaction. Based on them, by analyzing existing augmented reality exhibitions and surveys based on user evaluation factors, this research is meaningful in suggesting permanent exhibition spaces based on Augmented reality with high immersion where interaction with the audience is important. I hope this research would become a material for exhibition planning which can be used in planning permanent exhibition based on augmented reality in the future.

Collagen has been used as a functional material for foods and medicines, and has a function of enhancing the moisture retention of the skin. Now it is widely used in a variety of fields such as base materials for cosmetics. Therefore, it is expected that the demand for collagen and its application will be greatly expanded. This study was performed to investigate the physicochemical characteristics of glycoprotein extracted from cucumber. we manufactured glycoprotein using natural vegetable raw materials cucumber, and then analyzed physicochemical properties, analysis of the amino acid composition of cucumber collagen and compare with squid’s collagen. The content of aspartic acid was about 3 times as much as that of cucumber 18.57 wt% and squid 5.32 wt%. It was possible to check the fact that not only aspartic acid but also glutamic acid contains much more vegetable collagen than animal collagen. For example, cucumber contains 19.03 wt% glutamic acid. Otherwise, squid contains 7.5 wt% respectively. Moreover, the pH change was measured at a weekly rate of 25 °C and 37 °C for 8 weeks. At 25 °C, the cucumber collagen peptide remained very stable because of no pH change. After 8-week observation at a temperature of 37 °C, pH level is reduced by 0.5, suggesting that it have been demobilized by the amino acid component of the collagen. After analyzing the mass analysis, collagen had a molecular weight distribution below 281 Da. Considering that the molecular weight that can be absorbed into the skin is from 2000 Da, it is found that the vegetable collagen is a good biomaterial of absorbent material in the skin.

목적 : 자궁외 임신은 우리가 흔히 접하게 되지만 모성 사망을 일으킬 수 있는 질환이다. 때문에 저자들은 본원에서 치료받은 자궁외 임신 80예를 임상적으로 분석하여 자궁외 임신의 조기진단과 적절한 치료에 기여하고자 한다. 연구 방법 : 1991년 1월 1일부터 2000년 12월 31일까지 국립경찰병원에 입원하여 치료받은 80명의 자궁외 임신 환자를 대상으로 후향적 고찰을 시행하였다. 결과 : 조사 기간 동안의 자궁외 임신의 발생빈도는 1:68이었고, 25-34세에 63.7%가 발생하였으며, 제왕절제술을 포함해 개복수술의 이전 기왕력이 있는 경우가 52.6%이었다. 난관결찰술 후 자궁외 임신이 나타난 기간은 평균 6.5년이었다. 임상증상과 발현시기는 하복부 동통이 91.3%로 가장 흔했고, 평균 증상 발현기간은 7.6주였다. 대부분의 경우가 난관임신이었으며 환측 난관절제술이 56.3%에서 이루어졌다. 결론 : 본 연구는 자궁외 임신 환자의 진단에서 가임기 여성이 환자의 대부분을 이룬다는 사실과 증상발현과 내원 간의 시간이 중요 예후인자라는 것, 그리고, 치료 시 항상 자궁과 난소의 보전 노력을 해야 한다는 기본적인 사실들에 대해 우리의 주의를 다시금 상기시키는 데 모자람이 없다고 생각한다. Objective : Ectopic pregnancy can still cause maternal death, though we have undergone it frequently. So, we survey 80 cases ectopic pregnancies treated our hospital for early detection and proper management. Methods : In this study, the authors studied retrospectively 80 cases which had been admitted and treated at the department of Obstetrics and Gynecology, National Police Hospital from Jan. 1, 1991 to Dec. 31, 2000. Results : Incidence of ectopic pregnancy was one in 68 normal deliveries for 10 years, 63.7% of cases occurred in 25∼34 years-old age group, and 52.6% of patients had previous abdominal surgery including cesarean section. Average interval of tubal ligation was 6.5 years between the onset of ectopic pregnancy and tubal ligation. Lower abdominal pain was the most common clinical symptom developed in 91.3% of the patients. Average interval between the onset of symptom and LMP was 7.6 weeks. Most ectopic pregnancies were tubal pregnancies and salpingectomy was done in 56.3% of the patients. Conclusion : According to our study, ectopic pregnancy occurred most frequently in women in their reproductive age and one of most important prognostic factors is time between onset of symptom and arrival of patient at hospital. We must make our efforts to preserve utero-ovarian function in treatment of patients with ectopic pregnancy.
