  • u-City는 우리나라에서 최초로 개념이 수립되어 현재 32개 도시에서 건설중이거나 계획되어 있다. u-City는 도시건설에 있어 첨단 IT기술을 적용함으로서 도시내의 사물과 정보가 연결됨으로서 완성될 수 있다. 이러한 환경을 구축하기 위해서는 제도가 만들어져야 하고, 기술의 표준이 이루어져야 하며, 무엇보다도 첨단 IT 기술이 도시라는 변화를 예측할 수 없는 환경에서 안정적으로 작동될 수 있어야 한다. 따라서 도시공간에서 각 사물간의 정보를 연결할 수 있으면서도 안정적인 센서와 센서네트워크를 개발을 위해서는 기술개발 단계에서 실증실험이 필요하며, 본 연구에서는 도시 지상시설물 및 지하시설물의 센서 및 센서네트워크 기술을 검증할 수 있는 Test Lab의 조건과 역할에 대하여 제시하였다.

  • Purpose: The purpose of this study was to identify the effect of hand acupuncture on reduction of headache. Method: This study used a quasi-experimental pre-test and post-test design. 45 middle school girls who complained of headache were selected as subjects. The study lasted from November 2002 to June 2003. There were 22 girls in the experimental group while 23 girls were control group; convenience assignment was used. The two groups were homogeneous on characteristics. The experimental group received hand acupuncture. The treatment was to puncture corresponding points (A33, B27, M1, I2) on both the palm and the back of a hand with disposable acupuncture needles, and then remove them after a 20-30 minutes recess during which the subjects reclined on a bed. The data were analyzed using the SPSS PC with Fisher's Exact -test, and Mann Whitney U-test. Result: The results of this study were as follows: 1) In the experimental group, objective pain decreased after hand acupuncture (U= -2.51, p= .01). As for the objective pain degree, a significant reduction in voice change was observed in the experimental groups (U= -2.35, p= .02). Facial expressional changes were observed (U= -1.87, p= .06) and perspiration degree (U= -.99, p= .32) has reduced. However, these differences were not statistically significant between the experimental and control group. 2) Subjective pain degree decreased after hand acupuncture in the experimental as compared to the control group. 3) No statistical significant difference in comfort (U= -.29, p= .78) or distress (U= -1.51, p= .13) between experimental and control group were found. Conclusion: These findings indicate that hand acupuncture is an effective method for reducing headache. Therefore, hand acupuncture can be considered as an independent nursing intervention for headache reduction.

  • Mutagenicity of recombinant human erythropoietin (rhEPO) was examined in the reverse mutation test on bacteria, in the chromosomal aberration test on cultured mammalian cells and in the micronucleus test on mice. The reverse mutation test was performed by a plate incorporation method with or wothout a metabolic activation system (59 Mix) using Salmonella typhimurium strain TA100, TA1535, TA98 and TA 1537. The rhEPO did not significantly increase revertant colonies in any of the test strains under any conditions at dose levels ranging from 1000 H/ml to 62.5 lu/plate, compared with the vehicle control. In the chromosomal aberration test using cultured Chinese Hamster Lung (CHL) cells, the number of aberrant cells was not increased in the presence or absence of 59 Mix at concentrations of 1000 lU/ml to 250 lU/ml, compared with the vehicle control. In the micronucleus test, male ICR mice were given rhEPO intraperitoneally at a dose level of 25000, 12500 and 6250 lU/kg. The incidence of bone marrow micronucleated polychromatic erythrocytes was not different from that of the vehicle control. From these results, rhEPO is considered to be non-mutagenic under the present test conditions.

  • The PMT test results are compared with other in situ test such as Standard Penetration Test (SPT), Cone Penetration Test (CPT), Field Vane Test (FVT) and the laboratory test in order to investigate the correlationships for the strength parameters obtained from Busan and Incheon areas. Many proposed correlation formulas also make a comparative study and new correlation formulas for domestic soils are introduced. Limit pressure ( $P_1$) could be determined by P-log($\Delta$V/V) and Relative volume Method. PMT for the granular soils showed relatively high correlation with SPT, while CPT has good correlation with PMT for cohesive soil. The predicted undrained shear test ( $S_{u}$) by the PMT test results for Incheon and Busan samples showed low correlativity with proposed equations, therefore, new correlation formulas are proposed for domestic soils.s.

  • An experimental study has been carried out to reduce bending load, surface roughness and springback in bending process of stainless steel sheets. A U-bending test has been performed to investigate appropriate process parameters for getting better surfaces and accurate dimensions of stainless steel products. In the test, selected process parameters are die material, lubricant, and die clearance. Die materials used in the test are STD11(HRC60), STD11(TiCN), and AMPCO. From the test results, we can suggest that AMPCO dies are most suitable for reducing bending load and surface roughness of stainless steel sheets. And STD11 dies are favorable for avoiding spring-back in the stainless steel sheet-bending.

  • Purpose: This study was designed to evaluate the effect of home care nursing intervention with parenteral hydration and IV anti-emetic therapy on distress, nutritional status, anxiety, depression and QOL in gynecologic cancer patients who were undergoing combination chemotherapy. Methods: Quasi-experimental design was used to test the intervention. Changes of result variables were measured to evaluate effects of the intervention. variables consisted of serum lab results(auto analytic equipment for lab), symptom distress Scale(McCorkle & Young, 1978; Song et al., 2000), nutritional status(body weight, circumference of upper arm, serum protein, serum albumin, oral intake per day), anxiety(Spielberger, 1972; Kim & Shin, 1978), depression(Zung, 1965; Kim, 1995) and QOL(Padilla et al., 1983; Lee & Jo, 1996). Subjects were selected among gynecologic cancer patients(EG 15 patients and CG 15 patients) by convenient sampling. Data collection was done from June to Nov. in 2000. Data were analyzed by Chi-test and Mann-whitney U test using SPSS Win 10.0. Result: Hypothesis 1, the EG receiving this intervention equals to lab test(Hb & ANC, GOT & GPT, BUN & Cr) the CG, was supported(u=69.50 p=.074; u=94.50, p= .455; u= 89.50, p= .339; u=106.50, p= .803; u=75.00, p= .119; u=97.50, p= .523). Hypothesis 2, the EG has less symptom distress than the CG, was also supported(u=43.50, p= .004). Hypothesis 3, the EG has higher nutritional status than the CG, was partially supported on daily oral intake (u=59.00, p= .025). Hypothesis 4, the EG has less anxiety than the CG, was rejected(u=86.50, p= .280). Hypothesis 5, the EG has less depression than the CG, was rejected(u=203.50, p= .228). and the last hypothesis 6, the EG has higher QOL than the CG was supported (u=51.50, p= .011). Conclusion: Home care nursing intervention undergone in this study was found to be effective to reduce patients' symptom distress and to improve their oral intake and QOL.

  • To see both $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$(dissipate phlegm and promote vital energy circulation) and $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$(blood circulation and disperse blood stasis) influencing on thrombosis, contusion-hyperemia, and hyperlipidemia, at first we measured the density of FDP, the quantity of fibrinogen, prothrombin time, and the number of platelet of rat taken thrombosis by endotoxin. Secondly we measured the increase-rate of "paw swelling", the number of platelet, the quantity of fibrinogen, and prothrombin time of rat taken contusion-hyperemia. And then we measured the quantity of total cholesterol in serum and of H.D.L-cholesterol and of triglyceride and of phospholipid and of ${\beta}-lipoprotein$, its weight, and the variation of the quantity of electrolyte of rat taken hyperlipidemia by the oral-injection of choleserol. As a result, we can conclude as follows : 1. Out of the test of thrombosis, we can recognize not only the noticeable increae of the number of platelet and the quantity of fibrinogen, but also the noticeable decrease of prothrombin time and the density of FDP in case of $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$-injected rat and $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$-injected rat. 2. Out of the test of contusion-hyperemia, we can recognize not only the noticeable increase of the number of platelet and the quantity of fibrinogen, but also the noticeable decrease of prothrombin time and "increase-rate of paw swelling" in case of $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$-injected rat and $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$-injected rat. 3. Out of the test of hyperlipidemia, at first we can recognize that test rat's weight increased as close as that of normal rat. And we can recognize the noticeable decrease of the triglyceride and phospholipid and ${\beta}-lipoprotein$." Also, in case of the variation of electrolyte we can recognize the decrease of calcium and potassium in $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$-injected rat, and of sodium and magnesium in $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$-injected rat. Thus, as the above-mentioned, in covering thrombosis, contusion-hypermia, and hyperlipidemia, the effect of $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$ and $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$ can be recognized. Granting that $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$ reveals its effectiveness in thrombosis and contusion-hyperemia, and $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$ in hyperlipidemia, it can be inferred that contusion-hyperemia is like "model of blood stasis form" as thrombosis and hyperlipidemia "phlegm-retention diseases form", and both phlegm-retention and blood stasis have correlation each other.

  • The construction project of the Kijang research reactor (KJRR), which is the second research reactor in Korea, has been launched. The KJRR was designed to use, for the first time, U-Mo fuel. Plate-type U-7 wt.% Mo/Al-5 wt.% Si, referred to as U-7Mo/Ale5Si, dispersion fuel with a uranium loading of $8.0gU/cm^3$, was selected to achieve higher fuel efficiency and performance than are possible when using $U_3Si_2/Al$ dispersion fuel. To qualify the U-Mo fuel in terms of plate geometry, the first miniplates [HANARO Miniplate (HAMP-1)], containing U-7Mo/Al-5Si dispersion fuel ($8gU/cm^3$), were fabricated at the Korea Atomic Energy Research Institute and recently irradiated at HANARO. The PIE (Post-irradiation Examination) results of the HAMP-1 irradiation test were analyzed in depth in order to verify the safe in-pile performance of the U-7Mo/Al-5Si dispersion fuel under the KJRR irradiation conditions. Nondestructive analyses included visual inspection, gamma spectrometric mapping, and two-dimensional measurements of the plate thickness and oxide thickness. Destructive PIE work was also carried out, focusing on characterization of the microstructural behavior using optical microscopy and scanning electron microscopy. Electron probe microanalysis was also used to measure the elemental concentrations in the interaction layer formed between the U-Mo kernels and the matrix. A blistering threshold test and a bending test were performed on the irradiated HAMP-1 miniplates that were saved from the destructive tests. Swelling evaluation of the U-Mo fuel was also conducted using two methods: plate thickness measurement and meat thickness measurement.

  • It is generally known that the bonding strength of RC(Reinforced Concrete) flexural members strengthened by fiber sheet composites are sufficient and the bonding failure does not occur until the sheet failed. However, many researchers have been reported that, before the failure of the sheet, the bonding failure happens even though the bonding length is sufficient. This study was carried out to evaluate the effectiveness of shear key and U strip on flexural behavior of reinforced concrete beam structures. The ply number of CFS(Carbon Fiber Sheet), location of shear key, and existence or not of U strip were selected as the main test variables. Test results show that the behavior of a beam of which shear key is located in the nearby. of support and U strip is not existent, and having CFS of 1 ply is mostly improved.
