자판기가 꾸는 최고의 꿈은 무엇일까, 그것은 아마도 완전 무인화를 통해 유통의 모든 것을 대신하는 오토피아의 세계일 것이다. 자판기를 미래지향적 유통기기라 하는 것도, 또 산업계가 현재의 가능성보다는 내일을 더욱 중시하며 인고의 길을 마다하지 않는 이유도 분명 그 세계를 향한 꿈에 있을 게다. 이런 점에서 볼 때 최근 시장전개라 모색되는 오토 샵 시스템은 자판기의 미래지향적 꿈에 가장 근접한 기종이라 할 수 있다. 구성에 따라서는 수백가지 아이템을 인력 없이 판매할 수 있는 이 무인 시스템은 오토피아 세계를 향한 가능성의 시험대로서도 기대가 크다. 무인화에 있어서는 결코 한번 간 길은 되돌아가지 않는다. 일단 무인화가 되기가 힘들어서 그렇지 일정 단계에 도달하면 다시 유인으로 되돌아가기에는 너무 익숙하고 편해져 있게 마련이다. 오토 샵 시스템 역시 이 같은 흐름을 제대로 탈 수 있다면 오토피아의 대표주자로서 빠른 파급력을 기대해 볼 수 있다. 하지만 결코 쉽지 않은 길. 누구도 가지 않았기에 험난하고 힘들 수밖에 없는 그 길 위에서 오토피아 꿈들을 아직은 가능성 하나만을 믿고 매달려야 하는 시점이다. 금호 현장진단에서는 키오스텍에서 전개하는 '솔드아웃'을 통해 오토샵 시장의 가능성을 진단해 보는 시간을 마련했다.

본 연구에서는 우리나라 교육의 근본적인 문제를 학교교육의 저효율과 시험 위주의 교육왜곡이라는 두 가지 문제로 파악하는 한편, 과열된 과외, 치열한 입시경쟁, 미흡한 교육투자 등을 핵심문제로 보는 기존의 시각을 비판하였다. 또한 우리는 학교교육의 저효율과 시험 위주의 교육왜곡이 '교육실패'라고 부를 수 있을 정도로 매우 심각한 수준에 도달하였다는 것을 실증적 근거를 통하여 보여주고자 하였다. 본고에서는 우리의 교육실패에 대한 원인으로서 중앙정부의 교육부와 지방교육자치단체인 교육청이 우리 교육의 거의 모든 과정을 일일이 규제하고 통제함으로써 교육주체들의 유인(incentive)을 빼앗아가고 있는 점에 주목하였다. 우리의 교육실패는 교육부문에서의 정부실패라는 점을 강조하였다. 이러한 시각에서, 1980년의 교육개혁은 정부규제를 오히려 강화하여 문제를 해결하고자 하였다는 측면에서 실패한 개혁이며, 1995년의 개혁은 방향 설정은 제대로 되었으나 실행과정에서 많은 문제가 있었음을 지적하였다. 또한 향후 교육개혁의 방향으로 보다 과감한 규제완화(deregulation)와 분권화(decentralization)를 제시하였다. 구체적인 정책 대안으로는, 대학의 학생선발의 완전한 자유화, 시 도 교육청의 시 도청 관할로의 통폐합, 자립형 사립중고등학교 및 탈규제학교제도의 도입, 교원인사제도의 개혁, 과외에 대한 정부규제의 철폐 등을 건의하였다.

The bacterial motility in sand was studied with Alcaligenes xylosoxidans Y234 which is known as a strong decomposer of aromatic chemicals, especially toluene. Apparent motility coefficient (${\mu}$c,app) and apparent chemotaxis coefficient (${\mu}$c,app) for toluene were measured in the sands which have four different porosities. Adsorption ratio of Alcaligenes xylosoxidans Y234 on the sands was measured as 17%. The ramdom motility coefficients were 0.85∼1.68${\times}$10-3$\textrm{cm}^2$/sec, and decreased as the porosity of sands decreased. Apparent chemotaxis coefficients were measured as 1.1∼6.8${\times}$10-5$\textrm{cm}^2$/sec, and decreased as the porosity decreased and with time. The tendency of alcaligenes xylosoxidans Y234 movement towards toluene seemed very weak and showed little chemotaxis.

The apple leafminer, Phyllonorycrer ringoniella (Lepidoptera: Gracillariidae), is the most important pest on apple leaves and is not easy to be controlled with insecticides because of leafmining habit of its larvae. This study was undertaken to develop an artificial diet for mass rearing of the moth, and to look at their reproductive behavior. For developing an artificial diet the problem of diet contamination with microorganisms and how to supply artificial diet to first instar larvae have to be solved first. Artificial oviposition trial was successful with shadowy bottomside of various papers sprayed with apple leaf extracts. The highest activity of both calling and mating was observed within 30 min. after the onset of photophase and 3- to 4-day -old adults showed the highest mating rate. A ring-shaped sex pheromone gland was found at the intersegmental membrane between the 8th and 9th abdominal segments of the female. (E, 2)-4,lOtetradecadienyl acetate was identified as the major component from the femall gland extracts by the gas chromatography (GC) and GC-mass spectrometry. Additionally it was thought that (a-10-tetradecenyl acetate could be the second component of their sex pheromone.

While various factors in passenger and freight demand analysis affect on destination choice, a key factor, in general. is an attractiveness measure by size variable (e.g., population. employment etc) in destination zone. In order to measure the attractiveness, some empirical studies suggested that disaggregate gravity model are more suitable than aggregate gravity model. This study proposes that truck travelers trip diary data among Korean commodity flow data could be used to estimate the behaviors of incorporating trip departure time, activity duration and attractiveness in destination. As a result, the main findings of size and distance variables coincide with the conventional gravity model having a positive effect of population variable and a negative effect of distance variable. Due to disaggregate gravity modeling, the unique findings of this study reports that small trucks are more likely to choose short distance and early morning, morning peak and afternoon peak departure time choice. On the other hand, large trucks are more likely to choose long distance and night time departure time choice.

It is usually proposed that job security of old age workers is hampered by the structure of wage increasing with age. This paper sets forth a model to comprehend the characteristic of the old age workers' labor market and policy implications derived from it. In order to stimulate demand for old age workers, policy initiatives should be taken as follows : the wage criteria should be simplified which apply differently from one institution to other; incentives relatively favorable for employing old age workers' in manufacturing sector should be also given to service sectors; employment subsidy or other tax incentives should be given for labor contract after the retirement age; licensing and evaluation system for job ability should be introduced based on occupation & job analysis. To lower the reservation wage of workers, mortgage loan for house and long-term low interest loan for tuition fees should be developed together with stabilization of housing cost. Wedding culture which requires high expense should be amended. Above all, it is necessary to install reasonable social security system. Policy orientation should also pay attention to reduce labor supply of the old aged via aiding old age workers' firm opening and voluntary civil service together with developing various honor programs for members of civil corps.

This paper intends to analyze economic impacts of commitment period and initial allocation in emissions trading using computable general equilibrium (CGE) modeling. The fully dynamic CGE model with perfect foresight assumption is employed to illustrate (i) how a model displays economic impact of $CO_2$ regulation upon different commitment periods: one-year budget clearing vs. 5-year commitment period, (ii) how major 8 energy-intensive industries respond to different ways to allocate initial allowances. According to the results of the analysis, it IS found that market players are motivated to bank the permits and tend to sell permits in earlier stage and to buy permits in later stage of commitment period. This implies that banking allows permit trading within a commitment period, which supports the conclusions of Kling and Rubin (1997). Other findings are related to efficiency. That is, emissions trading surpasses command and control, in terms of economic efficiency and longer terms of commitment period converge on lower permit price, In long term, initial allocation based on value-added performs the lowest GDP loss among different initial allocations.

Recently, risk of space accident possibility increased in according to commercial space activity and space debris. It failed launch satellite second times in South Korea. Therefore was discussed on liability and insurance issue. Generally, discuss of space insurance be divided two type. Firstly, space insurance relevant to launching satellite and in-orbit. Satellite Launch Insurance and In-Orbit Insurance by the Satellite Operator Secondly, space insurance relevant to Third Party Liability. The former is to protect owner of satellite and operator. The latter is to liable and indemnify owner of satellite and operator's liability. US, UK, France, Russia, South Korea forced to buy space insurance following to domestic law. This is a brief overview of risk allocation and insurance practices in the commercial space transportation industry today. We begin with traditional space transportation, i.e., commercial satellite launches. This is a mature industry with known players. Industry practices have developed and legislation has been adopted in the U.S. and other countries over the past decades to address liability and insurance issues. The primary focus here is on U.S. law, but the discussion of industry practice applies more generally. We then move on to a more exotic form of space transportation: Commercial human space flight. Several private companies are now signing up space tourists for commercial suborbital human space flight, advertised to become available in the near future. The United States amended its launch legislation in 2004 to promote commercial human space flight. But questions remain as to how this new industry will respond to the risk allocation regime established by the U.S. legislation, which leaves both the space flight operator and space tourist exposed to risk and potential liability. As a general proposition, state statutes and contractual waivers alone cannot be relied upon to provide adequate liability protection, and insurance will be required. Federally mandated contractual waivers by space flight participants or liability caps would be helpful to complement insurance solutions. Eventually, as the industry matures, such practices could be extended to an international legal regime. For all the issues mentioned above, I have studied the existing international treaties and several country's domestic law to the space by referring U.S's Commercial Space Launch Amendment Act of 2004 and concluded that uniform legal regime to govern these insurance issues should be established domestically and internationally in the future.
