진보정당의 정책대안으로서의 지대조세제 : 2002년 서울시장 선거시 사회당의 공약을 중심으로 Focused on the Election Pledge of the Socialist Party in the 2002 Mayoral Election of Seoul Metropolitan City

김홍순 昌原大學校社會科學硏究所 2003 사회과학연구 Vol.10 No.-

이 글은 2002년 서울시장 선거에서 사회당이 내건 지대조세제 공약을 통해 우리나라 진보정당의 정책대안을 논리적 정합성, 실현가능성, 이념적 지향 그리고 대안의 모색 등 네 가지 차원에서 검토하였다. 결론적으로, 지대조세제는 논리적, 현실적 측면에서 일정한 한계가 있지만 이에 대한 보완이 이루어질 경우, 현실정책으로서 채용이 가능한 정책제안으로 분석되었다. 그러나, 이념적 지향차원에서는 지대조세제 공약이 사회당이 내걸고 있는 정강과 일정한 괴리가 있음을 알 수 있었다. 따라서, 지대조세제가 사회당의 정강을 실현하기 위한 정책수단으로서 활용되는 것은 무방하지만, 사회당을 대표하는 전략적 슬로건으로 활용되는 것은 부적절하다고 평가되었다.

프랑스 사회주의와 미국의 초월주의

박홍순 한국프랑스어문교육학회 2001 프랑스어문교육 Vol.12 No.-

Pierre Leroux, grand savant a` l'e´poque de la contestation politique et sociale, nous offre plusieurs revues importantes et une nouvelle vision du monde. Il occupe une place conside´rable parmi les socialistes de la premie`re moitie´ du 19e`me sie`cle et exerce une tre`s grande influence sur ses contemporains. Son influence ne se localise pas d'un seul co^te´. Les pense´es de P.Leroux conside´rait la question sous toutes ses forces, philosophiquement, socialement et litte´rairement. D'ailleurs, ses ide´es posaient les fondements du socialisme non seulement en France, mais dans la plupart des pays europe´ens. Cependant, l'influence de P.Leroux de´passait le cadre les intellectuels europe´ens. Elle s'vtait e´tendue outre-Atlantique aux Etats-Unis jusqu'en Ame´rique Latine. Gra^ce a` Elizabeth Peabody, libraire a` Boston, les Ame´ricains sons entre´s en contact avec les ouvrages de P.Leroux dans son magasin. Ralph W. Emerson, transcendantaliste, a aussi diffuse´ en Ame´rique des ide´es de P.Leroux. L'e´closion des doctrines de P. Leroux et des romans de George Sand correspond a` une des pe´triodes les plus ardentes de la re´forme sociale que n'ont jamais connue les Etats-Unis. Comme les historiens disent, cet 'a^ge de re´forme', se situant entre 1830 et 1860, a vu la floraison du parti socialiste, des communaute´s libertaires et des associations prole´tariennes. Dans ce travail, nous avons donc pu voir comment des ide´es de Pierre Leroux, ide´es telles que l'humanite´, la solidarite´ et la perfectibilite´ morale du genre humain ont influence´ les mouvements sociaux ame´ricains du 19e`me sie`cle. Puis, nous avons pu affirmer que P.Leroux e´tait content de constater l'existence d'un nombre d'asscociations puissantes ainsi que des salaires et des conditions de travail pour la plupart justes et raisonnables. Pour Leroux et ses amis comme Desmoulins, le gendre de Leroux et Joseph De´jacque, les termes 'association'et 're´publique' sont deux termes identiques. A leur avis, c'est la France qui doit offrir au monde l'exemple de la re´publique ve´ritable, et qui doit donc fournir l'exemple de l'association. C'est pourquoi, Leroux partage avec les transcendantalistes ame´ricains quelques ide´es philosophiques.

UR에 대응한 지역농업의 발전방안 : 시설원예농업을 중심으로 With an Emphasis on the Greenhouse Horticulture Farming

배흥규,김진수,이영기,정순재,정해진,이상학 東亞大學校 1995 東亞論叢 Vol.32 No.-

The production of greenhouse horticultural products in the east region of Kyungnam province is now increasing, though the productions of other argicultural sectors have been rapidly decreasing. However, as the agricultural market lies under the big pressure of the WTO system having a goal of free trade of all commodities, greenhouse horticultural farming in the region also meets with many new problems. To identify problems and prepare development strategies of the greenhouse horticultural farming for the easten Kyungnam region, 10 villages in Kimhae, Yangsan and Miryang areas were selected as sample areas and 204 greenhouse vegetable or floriculture farms were surveyed using prepared questionaires during March-April 1995. From the analysis of the regional survey results, the following proposals are suggested for the development of regional horticultural farming : 1) There were still old-fashioned greenhouse facilities such as tunnel-type vynil house, no heating system and man-power watering. Greenhouse facilities should be modernized and automated in order to overcome the severe labour shortage problem constraining the increase of the greenhouse farming size and the enhance the degree of the commodity value by uniform quality control and year-round production. The money for the modernization and automation of greehouse facilities ned to be supported by the central government, because farmers lack the ability to fund the investment. 2) Not many farmers visited agricultural extension officers to obtain cultivation techniques of greehouse horticulture farming, because extension officers lack the manpower to help solving the greehouse farming problems. Agricultural system should be adjusted to the changing agricultural production structure. Extension manpower specialized in greehouse horticultural farming need be increased and located in the regional extension offices. 3) The major reason of farmer's pessimistic prospect for the future of greegouse horticulture was the possibility of overproduction of some horticultural products. To avoid the overproduction, new entrants to the greenhouse horticultural farming of products already culticated extensively should be limited and the government support must be given to the existing greenhouse farms and major production areas. 4) Local goverment, associated agencies, and farmers should work hard cooperatively to increase the export of horticultural products especially to Japan, the largest importer of agricultural products in the world. Local governments and associated agencies can provide informations related to the export market and provide the fund for the facilities of standardization of export products. Farmers must observe the export contracts, even though the domestic price exceeds the export price. 5) Collective marketing activities of greenhouse products were found to be mainly limited to transportation and handling of sales revenue. Central and local government should support the formation and collective activities of cooperatives of specilaized producers to enhance the bargaining power of farmers. 6) The role of local government should be increased. They should actively participate in the orientation of regional greenhouse farming and play an important role in the marketing of regional greenhouse products.

펄스형 Nd-YAG 레이저 조사에 의한 법랑질 내산성 증가 기전에 관한 연구

이영순,손흥규 大韓小兒齒科學會 1996 大韓小兒齒科學會誌 Vol.23 No.3

The purpose of this study was to examine the mechanism of improving acid resistance of Nd-YAG laser irradiated tooth enamel and determine the most effective energy density for improving acid resistance. The bovine tooth enamel were lased with a pulsed Nd-YAG laser. The energy densities of exposed laser beam were varied from 10 to 70 J/㎠. To investigate the degree of improving acid resistance by irradiation, all the samples were submerged to demineralize in 0.5 N HCIO₄ solution for 1 minute. After 1 minute, 0.05% LaCl₃ was added to the solution for interrupting the demineralization reaction. The amounts of dissolved calcium and phosphate in the solution were measured by using an atomic absorption spectrophotometer and the UV/VIS spectrophotometer, respectively. To examine the mechanism of improving acid resistance, X-ray diffraction analysis, infrared spectroscopy, and scanning electron microscopy were taken. The X-ray diffraction pattern of the samples were obtained in the 10。∼80。2θrange with Cu-Kαradiation using M18HF(Mac Science Co.) with X-ray diffractometer operating at 40 KV and 300㎃. The infra-red spectra of the ground samples in 300 ㎎ KBr pellets 10 mm diameter were obtained in the 4000 cm to 400 cm range using JASCO 300E spectrophotometer. The scanning electron microscopy was carried out using JSM6400(JEOL Co.) with 500∼2000 times magnification. The results were as follow 1. The concentration of calcium dissolved from laser irradiated enamel with 50J/㎠ was significantly lesser than that of unlased control group (p<0.05) 2. From the result of the X-ray diffraction analysis, β-TCP, which increases acid solubility, was identified in lased enamel but the diffraction peaks of (002) and (004) became sharp with increasing energy density of laser irradiation. This means that the crystals in lased samples were grown through the c-axis and subsequently, the acid solubility of enamel decresed. 3. The a-axis parameter was slightly increased by laser irradiation, whereas the c-axis parameter was almost constant except for a little decrease at 50J/㎠. 4. In the infra-red spectra of lased enamels, phosphate bands (600∼500 cm), B-carbonate bands (870, 1415∼1455 cm), and A-carbonate band (1545 cm) were observed. The amounts of phosphate bands and the B-carbonate bands were reduced, on the other band, the amount of the A-carbonate band was increased by increase the energy density. 5. The SEM experiments reveal that the surface melting and recrystallization were appeared at 30 J/㎠ and the cracks were observed at 70 J/㎠. From above results, It may be suggested that the most effective energy density for improving acid resistance of tooth enamel with the irradiation of Nd-YAG laser was 50J/㎠. The mechanism of improving acid resistance were reduction of permeability due to surface melting and recrystallization of lased enamel and reduction of acid solubility of enamel due to decrease of carbonate content and growth of crystal.

The 1.06㎛ Neodymium-YAG Laser(800 micron hemisherical) is revealed a useful tool for percutaneous laser disc decompression(PLDD). Especially PLDD would be applied to the management of lumbar disc herniation with minimal intervention. Total irradiated energy to one level of disc space was bout 1000 to 2000 joules. We performed this method at 10 levels, in 7 cases of patients, consisting of 4 males and 3 females with an average age of 37.7 years. Five cases showed excellent and good results, were observed. In two cases, open surgery was required because of unsatisfactory results. The best results were obtained in the protrusion type of disc herniation. We have summarized some advantages of PLDD: a) safe and simple procedure in an outpatient setting, b) avoiding general anesthesia, late spinal instability, c) possibility of repetitive use.

Eledctrophysiological phenomena of pyramidal cells in the CAI area of the dorsal hippocampus were recorded from and filled with neurobiotin in anesthetized rats. The electropharmacological properties of membrane as well as the cellular-synaptic generation of rhythmic slow activity (theta)were examined. The intracellular response characteristics of these pyramidal cells were distinctly different from responses of inteneurons. Pyramidal cells had a high resting membrane potential, a low input resistance, and a large amplitude action potential. A afterhyperpolarization was followed a single action potential. Most of pyramidal cells did not display a spontaneous firing. Pyramidal cells displayed weak inward rectification and anodal break excitation. The slope of the frequency-current relation was 53.4 Hz/nA for the first interspike interval and 15.9 Hz/nA for the last intervals, suggesting the presence of spike frequency adaptation. Neurobiotin-filled neurons showed pyramidal morphology. Cells were generally bipolar dendritc processes ramifying in stratum lacunosum-moleculare, radiatum, and oriens. Commissural stimulation discharged pyramidal cells, followed by excitatory and inhibitory postsynaptic potentials (EPSPs and IPSPs). The frequency of theat-related membrane potential oscillation was voltage-independent in pyramidal neurons. At strong depolarization levels (less than 30 mV) pyramidal cells emitted sodium spike oscillation, phase-locked to theta. The observations provide direct evidence that theta-related rhythmic hyperpolarization of principal cells is brought by the rhythmically discharging interneurons. Furthermore, the findings in which interneurons were also paced by rhythmic inhibitory postsynaptic potentials during theta suggest that they were periodically hyperpolarized by their GABAergic septal afferents.
