With the rapid deployment of hipass$^{(R)}$, the congestion is inevitable due to the operation of the hipass lane system. Recently, SMART Highway project have developed a multi-lane mainline tolling system, called SMART Tolling system. To analyze the effectiveness of the system in terms of capacity, this study tries to estimate the capacity and its improvement of multi-lane tolling system based on current hipass$^{(R)}$ data. The methodology uses the saturation time headway. This follows three steps; 1) estimate the saturation time headway, using hipass$^{(R)}$ data, and capacity. 2) estimate two factors (the first one is dividing the one side lane width and lateral clearance factor ($f_w$) into two side one, the second one is dividing the capacity of hipass lane operating a circuit breaker into the capacity of hipass lane not operating, the last one is increasing factor of lane width). 3) calculate the capacity of multi-lane mainline tolling system. The results of method produced 2172~2187 veh/hour as smart tolling capacities, respectively. Those are higher about 370 veh/hour than the values from existing literature reviews. Additionally, saturation time headways were identified as lower by 0.5 seconds/veh than existing headways based on hi-pass$^{(R)}$ based one, which naturally implies the improvement in capacity. Some limitations and future research agenda have also been discussed.

This paper presents the investigation results of a research on how engineers can analyze the economic effect of the ETCS(Electronic Toll Collection System) installed to minimize the vehicle delays on freeway tollgates during toll payments. This research considered this economic effect to occur in the form of vehicle passing time reductions at the ETCS, and the multi-service queuing theory was applied to estimate these values. This research found: 1) When vehicles approaching tollgates show Poisson distribution and the service time of the ETCS shows Exponential distribution, the multi-service queuing theory would be applicable for estimating vehicle passing times at toll-gates, 2) Despite the ETCS placement, exit sections of tollgates give a greater reduction of vehicle passing times than entering sections due to more delays at conventional toll payments, and 3)The ETCS would not guarantee vehicle passing time reductions all the time, because in such a case as many vehicles were queuing at the ETCS, the total delay level for a toll gate would increase greatly. In addition, in order to examine the accuracy of the estimated vehicle passing values, this research compared the values from the multi-service queuing theory with the observed values from a set of field survey values at freeway toll-gates, and found that the two values were in a good agreement with a very low error range of 1-3 seconds per vehicle. Based on this result, the multi-service queuing theory was recommended for practice.

지난달 초 전국적인 집중호우 및 장마로 많은 사람들이 피해를 입었다. 때마침 부가세 신고를 앞두고 그런 일이 발생한 터라 국세청에서는 집중호우로 인한 피해 납세자들을 대상으로 납부기한 연장, 징수유예 등의 지원책을 내놓았다. 매년 여름이나 경루이면 폭우, 폭설로 인해 크고 작은 피해가 발생하는데, 이번호에서는 재해 발생시 종종 듣게 되는 납부기한 연장, 징수유예 등의 제도에 대해서 설명하고자 한다.

한국수자원공사에서 공급되는 댐용수는 댐건설 투자비와 댐운영 관리에 소요되는 비용을 회수하기 위하여 댐용수의 수요자로부터 요금을 징수하고 있다. 댐용수의 가격은 $\mathbb{\ulcorner}$댐용수 요금산정규칙$\mathbb{\lrcorner}$에 의거하여 댐용수를 공급하는데 소요되는 총괄원가를 보상하는 수준에서 결정되며, 1987년 이후부터는 지역간 부담의 형평성을 보장하는 차원에서 전국적으로 동일한 요금을 징수하고 있다(한국수자원공사, 2002).(중략)

The purpose of this study is to survey and analyze of the visitor's cognition of admission fee collection system in National Park. To accomplish the purposes, a questionnaire survey was employed in Songnisan National Park. The contents of questionnaire consist of the socioeconomic characteristics and the types of visiting, the activity, the cognition of admission fee collection system.339 samples of total 345 respondents were used for final analysis. As a result of the analysis, the socioeconomic characteristics and the types of visiting, the visiting purpose were showed similar trends with results from other National Park visitors survey. Most of respondents didn't recognize the raise of admission fee and how to use the admission fee. And they recognized that it is too expensive. Most of respondents recognized the joint collection of admission fee but they were strong against it. About the range of cultural assets in National Park, the cognition of 'Only Buddhism's assets in temple' was almost equal with the cognition of 'It includes not only cultural assets of inside and outside temple but also thick forest in National Park'. But most of respondents were strong against the collection of admission fee of cultural assets.

본 연구는 지속적인 교통량의 증가로 인해 발생되고 있는 고속도로의 혼잡을 해결하기 위해 한국도로공사에서 도입, 시범사업을 실시하고 있는 자동요금징수시스템의 효과를 분석하고자 한다. 이를 위해 하이패스라고 하는 자동요금징수시스템의 시범운영이 실시되고 있는 서울외곽순환고속도로의 판교, 청계, 성남 톨게이트를 대상으로 정량적 측면과 정성적 측면에 대해 시범사업 시행 전.후의 상황에 대해 비교.분석하였다. 시행 전.후를 비교해 본 결과, 정량적 측면에서 각 톨게이트 별 시간대별로 다른 결과를 보이긴 하지만 이용율이 비교적 높은 오전 첨두시에는 3개 톨게이트 모두 효과가 있는 것으로 나타나, 일정수준 이상의 이용율이 있는 경우는 효과가 있는 것으로 분석되었다. 정성적 측면의 이용자 만족도 조사에서는 하이패스 이용자의 84%가 만족하는 것으로 나타났으며 비이용자 선호도 조사에서는 응답자의 91%가 하이패스 이용의사가 있는 것으로 조사되어 효과가 있는 것으로 분석되었다. 결론적으로 7,000대의 단말기 과소 보급으로 아직까지는 평균 3.9%의 저조한 이용율을 보여 시범사업의 전반적인 사업효과가 제대로 나타나지 알고 있지만, 비교적 하이패스의 이용율이 높은 오전첨두에는 효과가 있는 것으로 나타난 점을 보아 2000년 12월부터 시행되고 있는 단말기의 추가 보급이 완료되는 시점에는 그 효과가 분명하게 나타날 것으로 예상된다. 따라서. 이용자의 만족도와 비 이용자의 선호도가 매우 높은 상황에서 현재의 시범운영상에서 발생된 문제점을 개선하여 하이패스를 확대.보급한다면 고속도로의 혼잡을 해결할 수 있는 좋은 방안이 될 것으로 판단된다.

The industrial Technology Development Program enables the recipient to set up technology infrastructure and to facilitate technology diffusion. In return, government charges royalties to the program recipient. However, the current royalty system is not effective form. This study analyzes the various aspects of royalty collection methods applied to the Industrial Technology Development Program and recommends the following: a) to establish a royalty collection system with appropriate charges for both fixed royalties and running royalties, dependent upon type of technology development b) to seek a method to setup different collection periods for industrial categories in consideration of product life cycle c) to review on ownership of intangible property. In addition, in order to manage the entire royalty process effectively, prompt establishment is needed in order for a responsible evaluation institute to create task forces to evaluate technology value, to transfer technology, to support technology commercialization, to collect and manage royalty and expand and report result.

Most countries that use a Value Added Tax(VAT) have exception for special cases with small enterprises who lack the ability to adapt in tax laws. VAT has been the most important tax. The simplified taxation system under VAT was introduced for small business taxpayers to perform tax liability easily and for government and taxpayers to get administrative efficiency by using a simple procedure. The present thesis suggests the conversion of simplified taxation system into general taxation as its improvement plan. That is, to abolish simplified taxation system, to convert it into general taxation and to apply the same tax base. The principle of fair taxation is not only important to realize tax justice, but also the principle of administrative efficiency important to increase the level of convenience for small enterprise taxpayers and efficiency for tax authorities.

This article considers how the rail track charges of the advanced countries are performed and derived political implication to Korail. In case of North America and Japan, rail track charges are being decided to collect the infrastructure maintenance cost. In European countries, the separation of infrastructure and operation is realized and the railroad track charges are based on MC+ principle. On the other hand, Korail is paying construction cost of KTX as well as maintenance cost in Korea. As for this, railroad reform including rail track charging should be reconsidered.
