So far we oriental medical doctors have referred to Shin(腎) as endocrine system, especially suprarenal gland, sexual gland and autonomic nervous system, thyroid etc. as well as kidney. But the sight on thyroid is weak and the relationship with Shin(腎) hasn't been suggested clearly. The purpose of this study is to find out the relationship between Shin(腎) with thyroid. The following are the results. 1. Ki Gi(氣機) of Shin(腎) is similar to the fuction of thyroid in that they are the base of human metabolism, influencing all the metabolism of human tissue. 2. Shin Yang(腎陽) and thyroid hormone are almost identical in that they are the base of Yang Gi(陽氣), the former as source of heat energy, the latter as energy hormone. 3. Shin(腎) and thyroid hormone are almost the same in that they activate growth of human body. 4. Ki Gi(氣機) of Shin(腎) such as Ju Gol(主骨), Saeng Su(生髓), Tong uh Noi(通於腦) is similar to the effects of thyroid hormone on bones, central nervous system and hair 5. The symptoms of deficiency of Shin Eum(腎陰虛) are almost identical with those of hyperthyroidism, so the process of Yang Hwa Gi(陽化氣) caused by exuberance of Yang due to deficiency of Shin Eum(腎陰虛陽亢) is similar to excessive metabolism caused by hyperthyroidism. 6. The process of Eum Seong Hyung(陰成形) caused by preponderance of Eum due to deficiency of Shin Yang(腎陽虛陰盛) is similar to the lowering of metabolism caused by hypothyroidism. 7. Deficiency of Shin Eum(腎陰虛) is similar to hyperthyroidism, deficiency of Shin Yang(腎陽虛) to hypothyroidism. But there are major difference in edema and the fuction of intestine. To conclude, Ki Gi(氣機) of Shin is similar to the function of throid in many respects. I hope that there will be further studies on the relationship beteen thyroid malfuction with deficiency of Shin Yang(腎陽虛) or of Shin Eum(腎陰虛) in the future.

Objectives : The aim of this study was to investigate immunohistochemical expression of CK7, CK19, CK20, SMA and Ki-67 in Adenoid cystic carcinoma(ACC) of the Head and Neck. Material and Methods : Sixteen patients who were treated in Chungbuk National University Hospital from 1992 to 2004, were included in this study. Ten ACCs, 3 MECs, 1 Salivary duct carcinoma, 1 Adenocarcinoma(NOS), and 1 cacinoma ex pleomorphic adenoma were analyzed immunohistochemically for CK7, CK19, CK20, SMA, and Ki-67. Results : CK7 was expressed in 100% of the adenoid cystic carcinoma and 75% of the other tumors. CK19 was expressed in 75% of the adenoid cystic carcinoma and 100% of the other tumors. CK20 was not expressed in all tumors. SMA was expressed in 88.9% of the adenoid cystic carcinoma and not expressed in the other tumors. Ki-67 was expressed in low level in the adenoid cystic carcinoma. Conclusion : The Ki-67 index could explain the natural course of tumor. Immunohistochemistry of CK7, CK19, CK20, SMA and Ki-67 expression in Adenoid cystic carcinoma may provide useful information to diagnosis.

The effect of aqueous extract of processed Xanthii fructus (PXF) on cell viability and histamine release from mast cell has been investigated. PXF showed higher cell viability than unprocessed Xanthii fructus (XF) at the concentrations of 5 and 10 mg/ml. Aqueous extract of PXF and unprocessed XF inhibited compound 48/80-induced systemic anaphylaxis in mouse. Both PXF and unprocessed XF dose-dependently inhibited histamine release from rat peritoneal mast cells by compound 48/80 to the similar extent at 0.01, 0.1 and 1 mg/ml. Our studies provide evidence that processing of XF may be beneficial to reduce cytotoxicity in high concentration (at 5 and 10 mg/ml) but does not affect on anti-allergic activity.

Compressed natural gas has good potential for alternative vehicle fuel due to its economical and clean characteristics. However, the composition of natural gas based on production location is known to affect performance and emissions of CNG engine. Thus, the objective of this paper is to clarify the effect of fuel composition on combustion and emissions of CNG engine. This paper presents combustion characteristics obtained from running a 2.5L, 4-cylinder CNG engine retrofitted IDI diesel engine with engine dynamometer. BSFC, emissions, fuel consumption and combustion pressure were measured under steady state operating conditions especially at partial load for CNG engine. Based on the experimental results, we found that CNG composition affects engine performance, fuel conversion efficiency and burning rate.

Wind turbine noise become main environmental problem as wind energy have been installed all around. Noise from large wind turbine give annoyance to listener, moreover it increase loading to whole system by restricting blade tip speed. However accurate noise mechanism of wind turbine is not yet examined. This paper reviewed noise source and analysis theory. Broadband noise if main component of wind turbine noise and airfoil self noise is main noise source. These make acoustic analogy hard to apply for analysis. For this reason, experimental equation is method for wind turbine noise prediction up to now. Spectrum analysis shows that vortex shedding noise exists around $1k{\sim}2k$ Hz. This region is most sensitive frequency range to human. Thus it is necessary to reduce this noise source.

In-plane ESPI(Electronic Speckle Patten Interferometry)was devised to measure in~plane defamation and rotation of a specimen with laser in this study. The conventional measuring methods of surface deformations such as the strain gauge have many demerits because they are contact and point-to-point measuring ones. But that ESPI is noncontact, nondestructive and whole field measuring method can overcome previous disadvantages. We used ESPI which is sensitive to in-plane displacement for measuring in-plane deformations of a disk. First of all, the system calibration was done due to an in-plane rotation before getting deformations of a disk. Finally we showed good agreement between theexperiment results and those of the FEA(Finit Element Analysis).

Experimental research was conducted to investigate the characteristic of various CFRP strengthening methods. A total of 4 specimens of 3.3m length were tested in four point bending after strengthening them with externally bonded CFRP plates. The CFRP plates were bonded without prestress or with prestress levels of CFRP plate strain $0.5\%$. The non-prestressed specimen without anchor plate failed by separation of the plate from the beam due to premature debonding while the non-prestressed specimen with anchor plate failed by CFRP fracture and showed the significant increase of ductility capacity. In addition, the prestressed specimens failed by concrete compression failure. The maximum load and ductility capacity were most significantly increased.

본 논문에서는 다공질 실리콘에 대한 에탄올과 메탄을 가스 감지 특성을 측정하고 전기 전도도의 변화를 고찰하였다. 우선 HF와 에탄올의 혼합 용액내에서 n-type의 웨이퍼에 일정 전압을 인가하여 다공질 실리콘을 형성한다. 다공질 실리콘은 수직한 방향으로 $55{\sim}60{\mu}m$ 두께로 균일하게 형성되었다. 다공질 실리콘을 이용하여 소자를 제작하고 에탄올과 메탄올 가스를 주입하여 전류-전압 특성을 측정하였다. 기존의 다공질 실리콘 에탄올 센서와는 달리 turn-on 시 센서에 흐르는 전류가 빠른 시간내에 일정한 값으로 도달하였고 turn-off시에도 같은 결과를 보였다. 다공질 실리콘 표면에 흡착된 에탄올과 메탄올 가스는 전류의 흐름을 방해하는 surface charge를 스크린하여 전기 전도도를 증가시킨다. 또한 흡착된 가스가 dangling bonds를 passivation하여 전류를 증가시키는 것으로 생각된다.
