The dose-response effect of polysaccharide extracts(PS-1) from Artemisia iwayomogi was investigated under various hepatic disease models. Silymarin, DDB and UDCA were used as reference compounds. We found that the maximal effective dose of PS-1 was 100 ㎎/㎏ b.wt. in CCl_4-induced hepatotoxicity, D-galactosamine-induced hepatitis, in ANIT-induced cholestasis and 300 ㎎/㎏ b.wt. in CCl_4-induced chronic liver disease, 30 ㎎/㎏ b.wt. in chronic bile duct ligation and chronic ethanol fatty liver. These findings suggest that PS-1 fraction protects the hepatocyte against various hepatic injuries, and this fracton might be of therapeutic value.

The adsorptions of nitric oxide and carbon monoxide on Pt(111) surfaces have been studied by using LEED, AES, and TDS(Thermal Desorption spectroscopy). The adsorbed species of NO is predominantly molecular on the Pt(111) surface at room temperature. A main desorption peak of TDS is attributed to the molecular adsorption at 360K. With increasing No exposures, a shoulder peak at 480K which may be attributed to the defect site adsorption is appeared. The desorption rate order for No desorption is 1st order and the desorption energy for NO calculated by Redhead equation assuming pre-exponential factor v_1=10^13 sec^-1 is 21.7Kcal/mol. The adsorption of carbon monoxide is also molecular on Pt(111) surface at room temperature. The TDS results showed only a single broad peak at 460K, which is attributed to molecular adsorption. The desorption order for CO desorption is 1st order as well as NO and the desorption energy for CO is 28Kcal/mol.

Interactions between oxygen and carbon monoxide on Ni surface were studied by means of XPS at room temperature in UHV system attached with a. quadrupole mass spectrometer. Adsorption of CO on Ni surface precovered with oxygen are followed by three step. It was noted that CO₂ gas are formed by reaction of preadsorbed oxygen and CO molecules at initial step, and the second step is followed that precovered oxygen and CO molecules are coadsorbed, and during the high CO exposure the less pread-sorbed oxygen is, the more adsorbed CO. It could be attributed to the fact that the existence of oxygen on the Ni surface reduced the sticking coefficient of CO. Dissociative adsorption of O₂ on Ni surface were inhibited by the preadsorbed CO molecule at initial oxygen exposure. The dissociative adsorption of the preadsorbed CO increased with increasing exposures of O₂ and Ar. This was very well explained by the model of a collision-energy transfer, that a collision between the preadsorbed CO and O₂ or Ar gas cause to increase an amplitude of vibration mode contributed to dissociative adsorption so that the preadsorbed CO molecule is dissociated by the interaction of oxygen atom of adsorbed CO and Ni atoms.

A multipurpose Ultra High Vacuum chamber was designed and constructed in this laboratory. This enables us to be equipped with various analytical instruments such as Ar-ion gun LEED optics, Electron analyzer, and Quadrupole mass spectrometer etc. The 4-Grid LEED optics, a product of Omicron company in West Germany, was equipped with the UHV chamber and the LEED power supply was designed by this group. Turbo-C language figured out Auger spectra of the ad-species by means of the computer interface. The resolution of Auger electron spectrometer was measured with a constant primary electron beam energy. The results showed that the resolution was independent of the primary electron beam energy, but depends on the modulation voltage. Also, it was revealed that the resolution of 4-Grid optics was more improved than that of 3-Grid optics.

폭풍시 사구의 침식각에 따른 해안단면의 침식에 관한 연구

This EDUNE model developed by Kriebel was used for predicting storm-induced beach and dune erosion due to elevated water levels and waves. This model was based on the convolution integral involving a erosion-force function and an exponential erosion-response function. This numerical model adopted the equation of sediment continuity and a dynamic equation governing the cross-shore sediment transport due to a disequilibrium of wave energy dissipation levels. These equations are solved numerically by an implicit, double-sweep method to obtain the changes in position of elevation contours in the profile. In this study, the changes of a beach profile and dune erosion have been simulated for varying the dune erosion angle due to storm. The range of angle was 0.1~0.4 radian. It is shown that erosion rate is increasing according to the decrease of erosion angle.

Purpose: The purpose of this study was to examine the effect of hand massage through Korean hand acupuncture therapy on nausea, vomiting and anorexia induced by chemotherapy in cancer patients. Method: Subjects consisted of 40 patients with cancer who were hospitalized and had chemotherapy at D university hospital in D city, Korea. These subject were assigned randomly to a hand massage throght Korean Hand Acupuncture Therapy (experimental group: n=20, control group: n=20). The data were collected from April 1 to September 15 in 2005. All the patients were assessed for their nausea, womiting and anorexia; Nausea and vomiting were measured with Rhodes INVR(index of Nausea, Vomiting by Rhodes and McDaniel) and Anorexia was measured with VAS(Visual Analogue Scale). As an experimental treatment, the hand massage through Korean Hand Acupuncture Therapy was applied three times a day for three consecutive days. The data were collected at the time of 4 hours before the start of chemotherapy, 24hours and 48hours after hand massage respectively. The data were analyzed with SPSS/WIN 11.5 program using frequency, percentage, χ²-test, t-test, repeated Measures ANOVA. Reslt: Severity of nausea and vomiting in hand massage through Korean Hand Acupuncture Therapy group was significantly less than of control group(F=28.10, P=.000). Severity of anorexia in hand massage through Korean Hand Acupuncture Therapy group was also significantly less than that of control group(F=31.24, P=.000). Conclusion: Hand massage through Korean Hand Acupuncture Therapy is effective for relieving patients' nausea, vomiting and anorexia during chemotherapy. Therefore, it is proposed that hand massage through Korean Hand Acupuncture Therapy can be applied as a supportive as a supportive nursing arbitration method to relieve naussa, vomiting and anorexia in patients who are getting chemotherapy.

본 연구는 노동시장에서 일할 수밖에 없는 여성노인의 다중차별 경험을 파악하여 이들의 노동권을 보호하고 차별을 해소하기 위한 방안을 마련하는데 목적이 있다. 이를 위해 노인집중 고용 업종에 종사하는 60세 이상 여성노인 14명을 대상으로 심층면접조사를 진행하였다. 본 연구 결과, 일할 수밖에 없는 여성노인들은 노동시장의 입직 단계에서부터 성별, 연령, 건강의 다중차별에 의한 상시적인 고용불안과 사회안전망에서의 배제를 경험하였다. 또한 일하는 조직의 불평등 지배체제 특성으로 일상화된 고용불안, 열악한 노동조건과 복지제도의 미비, 노인친화적이지 않은 노동 강도와 근무 제공, 노인 노동 평가 절하에 따른 조직 위계 문화와 관행, 과도한 노동 제공의 요구와 성희롱의 일상화, 조직 내에서 이해를 대변하는 데 어려움을 경험하는 것으로 나타났다. 본 연구 결과를 바탕으로 일할 수밖에 없는 여성노인의 다중차별을 해소하기 위한 법과 제도의 개선, 사회안전망 강화, 여성노인 노동자 이해대변단체 조직화 지원을 제언하였다. This study aims to (i) identify the experience of multiple discrimination among older women, who have no choice but to work in the labor market; (ii) protect their labor rights; and (iii) resolve discrimination. To conduct this study, we performed an in-depth interview survey with 14 older women aged 60 or older who are engaged in the elderly intensive employment sector. Under the result of this study, older women, who have no choice but to work, have experienced constant employment insecurity and exclusion from the social safety net due to multiple discrimination in gender, age, and health from the employment stage in the labor market. In addition, because of inequality organizations, they have experienced as follows: employment insecurity that became common, poor labor conditions and inadequate welfare systems, unfriendly labor intensity and provision of work, organizational hierarchical culture and practices due to devaluation of elderly labor, demand for excessive labor provision and sexual harassment routinely, and difficulties in representing understanding within the organization. Based on the results of this study, therefore, this study provides suggestions to resolve the multiple discrimination of older women, who have no choice but to work, including but no limited to, improve laws and systems, strengthen the social safety net, and organize support for the organization of interest groups for older women workers.
