본고에서는 안압지발굴보고서에 보고된 기와를 문양과 제작기법적인 측면을 중심으로 관찰하여 분류한다. 분류한 각 기와를 건축물 지붕재로서의 기능을 고려하여 세트관계를 파악한다. 그런 다음 문무왕 19년, 679년에 제작된 “의봉4년개토(儀鳳四年皆土)”명 암키와를 중심으로 편년을 시도한다. 2002년 국립경주박물관에서 간행한 도록 『안압지관』에 소개되어 있는 배치도를 보면, 안압지 내의 유구는 연못과 초석건물지 외에 초석건물지 하층에 시기를 달리 하는 담장 열이 있다. 이것을 기초로 안압지내 유구를 담장, 연못, 건물지로 구분하여 축조순서를 살펴본다. 안압지 내의 가장 중심이 되는 유구를 건물지 I로 명명하고, 그 창건시기를 세트관계로 파악한 기와, 즉 “의봉4년개토”명 암키와를 기초로 하여 679년으로 본다. 이와 같은 작업은 안압지가 축조되기 전과 후, 이 공간의 주체에 대하여 접근하는데 기초자료가 될 수 있을 것이다. In this thesis, I sorted with roof-tile, which were uncovered by the Anapji Archaeological Expedition, according to manufacturing technique and design. Each roof tile which classifies considers the function as roof-tile of the building and the relationship of the set. Then 19 years and Munmu-King(文武王), Basd on Uibong-4years-Gaeto(儀鳳四年皆土) female roof-tiles which was produced in 679 years I attempts a chronology. When sees the layout sketch which is introduced to the atlas Anapji which publishes from 2002 Gyeongju national museum That is a stone wall in the pond and building outside time on building lower stratum differently in the Anapji. based on the contents which explains from before I tries to observe a establishment order to be the fence, the pond, with building to divide site in Anapji. From Anapji the most building where is center gave a name with building 1, Then The establishment time is 679 years on Uibong-4years-Gaeto(儀鳳四年皆土) of female roof tile in the center. The present paper expects. After the criminal record Anapji being built, Will be the possibility becoming the fundamental data which is the possibility of knowing about the master of this space.

This study was designed to find out an alternative to artificial pollination in kiwifruit production. The parthenocarpic kiwifruits induced by (N-2-chloro-4-pyridyl)-N-phenyl urea (CPPU) treatment tended to be less attractive due to deep furrowing and excessive outgrowth of stigma in mature fruits. Especially, on flower buds after CPPU spray, severe fruit-drop was induced. It was considered enough to spray CPPU at more than 4ppm to attain sufficient fruit set but needed to spray CPPU at more than 16ppm to attain marketable fruit size. When CPPU at 16ppm was sprayed to the same flower once, twice or three time, the fruits received CPPU treatment more time was larger but less attractive. Application of CPPU mare than at 16ppm seemed to be necessary to produce fruits heavier than 80 gr. Enlargement of the fruits received CPPU treatment mainly occurred cross wisely and vertical development was not affected and thickening of outer pericarp primarily contributed to the fruit enlargement. Difference in flesh color or contents of vitamin C and sugars between control fruits and CPPU-treated fruits was not noticed. In conclusion, CPPU treatment to induce parthenocarpic kiwifruits could be commercially applicable, only the method for improving fruit appearance is worked out.

This work was accomplished to determine the effect of 2,4-dinitrophenol (DNP) on in vivo nitrate reductase activities(NRA) in the shoots of 6 day old rye(Secale cereale L.) seedlings. The NRA in the shoots of rye seedlings pretreated with 0.5mM DNP was higher than that of the control group in all the experimental conditions as below. The optimal concentration of KNO_3 for maximum NRA was 10mM in both the control and treated group. The NRA accumulated with the treatment of 10mM KNO_3 was gradually increased for 4 hours in both groups, and then maintained constantly. On the other hand, the NRA occurred per hour was highest at 1 hour in both groups, while it was declined subsequently. The optimal pH for NRA was 7.5 in both groups. The daily pattern of NRA was markedly decreased for 4 days in both groups, and decreased slowly to 7 days. The NRA was greatly inhibited in the solutions of 200mM KCI and NaCl. According to the treatment time with the solutions of 200mM KCI and NaCl, the NRA was extremely inhibited at 2 hours, thereafter recovered slowly from its inhibition effects.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

The Compression molding process is widely used in the automotive industry to produce parts that are large, thin, light-weight, strong and stiff. Compression molded parts are formed by squeezing a glass fiber reinforced polypropylene sheet, known as glass mat thermoplastic(GMT), between two heated cavity surfaces. In this study, the an isotropic viscosity of the Unidirectional Fiber-Reinforced Plastic Composites is measured using the parallel plastometer and the composites is treated as an incompressible Newtonian fluid. The effects of molding parameter and fiber contents ratio on longitudinal/transverse viscosity are also discussed.

During a compression molding process of Unidirectional Fiber Reinforced Thermoplastic Composites, control of filling patterns in mold and distribution of fiber is needed to predict the effects of molding parameters on the flow characteristics. To obtain an excellent product and decide optimum molding conditions, it is important to know the relationship between molding conditions and viscosity. In this study, the anisotropic viscosity of the Unidirectional Fiber-Reinforced Polymeric Composites is measured by using the parallel plastometer. The model for flow state has been simulated by using the viscosity. The composites is treated as an incompressible New-tonian fluid. The effects of longitudinal transverse viscosity ratio A and slip parameter α on buldging phenomenon and mold filling patterns, are also discussed.

In recent years, compression molding of lone fiber-reinforced thermoplastics has been increased in commercial aspects. In the process of compression molding of composites, the flow analysis must he developed in order to accurately predict the finished part properties as a function of the molding process parameters. In this model FRTP is assumed to be nonisothermal fluid, which has different viscosities in extensional and in shear. For verification of the model, the formation of a knit line in the L-shaped parts is compared with that of experiments results. In this paper we will discuss the effects of extensional & shears viscosity ratio ξ and slip parameter α on the other mold fill-ing parameters

If we apply a circularly polarized light to semiconductors, in the external static magnetic field, then the electrons absorb the light at the resonance frequency, resulting in the interband-transition from valence band to conduction band. The linewidth is affected by various mechanisms. Here we will compare the isolated operator method and the single operator method.
