The purpose of this study was to explore young professionals' housing characteristics reflected in TV drama in order to illuminate gap between housing reflected in media and that in reality. Three series of TV drama broadcasted within the last five years (2008-2012) that had one or more characters who were identified to be young professionals in their 20s living apart from their parents were selected for this study. Socio-economic and housing characteristics of the characters were analyzed mainly using visual cues, dialogues, and Internet search. It was found that many dramas tried to include non-traditional housing characteristics such as a rooftop house and non-family households to reflect limited housing affordability of young professionals. Considering the size, interior and furnishing of the units, however, the real cost to achieve the same level of housing status could be over the affordable level of general young professionals in reality.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

In this dissertation, we have studied on the fabrication of Sr ferrite plastic magnet with additional Nd. First, we selected SrO5.9F₂O₃of nonstoichimatric composition as the basic composition of specimen ferrite since its magnetic property was excellent. Then, we added Nd to the specimen. In order to control the properties of the particles on fabrication of magnetic powder, 0.3wt% CaCO₃, 0.2wt% SiO₂, 0.twt% Al₂O₃and 0.5wt% Na₂SiO₃were added. For carbon coating ont he compound specimen, 5wt% polyvinylalchohol was added and then the compound specimen was calcinated under N₂environment at 1,225 ℃. After performaing grinding process for 18 hours, we obtained 1.0~1.2㎛ size of single domain magnetic powder. We added 1 wt% silane coupling and 1 wt% calcium stearate to the Sr ferrite powder with additional Nd, and then mixed them well. Next, we pelleted them after kneading them, using polyamide12 as a binder. The pelleted specimen was injection-moulded using anisotropic mould under magnetic field of 12kOe. As the results of property tests for the fabricated specimen magnet, we find that the fabricated magnet has the following excellent peroperties at Nd 12.5wt%: bHc=2.84kOe, Br=3.23kG and (BH)max=2.49MGOe.

비만은 동맥경화의 위험인자로서 혈중에 triglyceride의 농도를 종가시키고, 상대적으로 HDL-Cholesterol의 농도를 감소시킴과 동시에 수축기 혈압을 상승시킨다. 본 연구에서 홍삼제품류를 4년 또는 5년 동안 복용해 온 건강한 사람 (ginseng군)과 홍삼제품을 복용하지 않은 건강한 사람 (control군)을 대상으로 하여 신체 계측치로부터 비만지수를 구하고 이것과 혈중의 triglyceride (TG)농도, TG/HDL-Cholesterol ratio 및 수축기 혈압과의 상호관계를 연구한 바, ginseng군에서는 대조군에 비해 혈중의 TG 농도가 일정하게 유지되었고, TG/HDL-Cholesterol ratio 및 수축기 혈압도 일정하게 유지되었다. 이러한 현상은 ginseng군에서 기호품으로 alcohol을 섭취하거나, 흡연을 한 경우에도 상관없이 일정하게 유지 되었다. 이 결과는 홍삼제품류를 장기 복용하면 비만의 저하 및 고혈압 또는 동맥경화의 위험인자가 억제될 수 있고, 결론적으로 비만, 고혈압 및 동맥경화를 예방할 수 있을 것으로 추정한다. Obesity is the risk fcactor of atherosclerosis and not only increases triglyceride concentration in blood but also decreases relatively the ratio of TG to HDL-Cholesterol in blood. In case of obesity, systolic blood pressure is also increased in responding the increase of TG in blood. Index of obesity in red ginseng-taking group (ginseng group) was lower as compared with non-red ginseng-taking group (control group). The TG concentration, the ratio of triglyceride to HDL-cholesterol in blood and systolic blood pressure were decreased in the subjects of ginseng group compared with that in control group. It is inferred that long-term intake of ginseng products may help to prevent the risk of atherosclerosis and obesity.

Objectives: This study analyzed the difference in color caused by different thickness in enamel layer of composite resins when applied with single and layering placement technique, and evaluated if the results agreed with the shade guide from the manufacturers to verify reliability of the color matching process of the manufacturers. Materials and Methods: For single composite resin samples, 6 mm diameter and 4 mm thickness cylindrical samples were fabricated using Ceram-X mono (DENTSPLY DeTrey) and CIE L*a*b* values were measured with spectrophotometer. Same process was done for layering compositie resin samples, making 3 dentinal shade samples, 4 mm thickness, for each shade using Ceram-X duo (DENTSPLY DeTrey) and enamel shade resins were layered in 2 mm thickness and CIE L*a*b* values were measured. These samples were ground to 0.2 mm thickness each time, and CIE L*a*b* values were measured to 1 mm thickness of enamel shade resin. Results: Color difference (△E*) between single and layering composite resin was 1.37 minimum and 10.53 maximum when layering thicknesses were between 1 mm and 2 mm and 6 out of 10 same shade groups suggested by manufacturer showed remarkable color difference at anythickness (△E* > 3.3). Conclusion: When using Ceram-X mono and duo for composite resin restoration, following the manufacturer's instructions for chossing the shade is not appropriate, and more accurate information for Ceram-X duo is needed on the variation and expression of the shades depending on the thickness of the enamel.
