The climatic change convention is a matter of grave concern to the whole world. As a countermeasure against the climatic change convention, the Korean Government permits the sale of diesel passenger cars since 2005. In this paper, we analyse the effect of the sales permission of diesel passenger car as the countermeasure. The share, carbon emission, and pollutants emission of each type of passenger cars are analysed using system dynamics. The result is that the carbon emission is decreased by $5.5\%$ but the pollutants emission is increased by $5\%$. If the pollutants emission was dealt successfully with, the sales permission of diesel passenger cars would be a good countermeasure against the climatic change convention.

해체공사의 수요증가와 사고 위험성을 고려하여 정부는 20년 건축물관리법을 시행해 해체공사의 안전관리를 개선하고자 하였다. 그러나 건축물관리법 제 30조 건축물의 해체 허가에 따른 기준은 일률적이기 때문에 규모에 따른 허가대상 건축물의 구분은 불합리할 수 있다. 또한, 해체공사는 건축물의 구조 유형에 따라 공사 난이도 및 발생 재해의 형태가 달라질 수 있기 때문에 본 연구는 건축물관리법상 신고대상에 속하는 조적조 등의 소규모 건축물의 구조 유형을 고려한 해체공사 안전관리 개선 방안을 제시하고자 한다. 본 연구의 순서는 (I) 건축물관리법 기준; (II) 건축물의 구조 유형에 따른 해체공사 분석; (III) 해체공사 허가대상 세분화 순으로 진행되었다. 연구 결과 건축물관리법상 허가대상은 과거 해체공사 실적의 10% 정도, 조적조는 2.43%에 불과하였다. 허가대상 기준을 세분화한 결과 조적조의 경우 연면적 100㎡이하일 때 허가 및 신고대상의 수가 유사해짐을 확인하였다. 이를 통해 이해관계자는 1) 해외와 같이 규모에 관계없이 특수구조 건축물에 강화된 안전관리 기준을 적용하거나, 2) 건축물의 구조 유형에 따라 해체공사 허가 대상 기준을 세분화하는 방식 등을 활용한 해체공사 안전관리를 개선할 수 있다.

Information Centric Networking (ICN) has recently attracted great attention. It names the content decoupling from the location and introduces network caching, making the content to be cached anywhere within the network. The benefits of such design are obvious, however, many challenges still need to be solved. Among them, the local caching policy is widely discussed and it can be further divided into two parts, namely the cache permission policy and the cache replacement policy. The former is used to decide whether an incoming content should be cached while the latter is used to evict a cached content if required. The Internet is a user-oriented network and popular contents always have much more requests than unpopular ones. Caching such popular contents closer to the user's location can improve the network performance, and consequently, the local caching policy is required to identify popular contents. However, considering the line speed requirement of ICN routers, the local caching policy whose complexity is larger than O(1) cannot be applied. In terms of the replacement policy, Least Recently Used (LRU) is selected as the default one for ICN because of its low complexity, although its ability to identify the popular content is poor. Hence, the identification of popular contents should be completed by the cache permission policy. In this paper, a cache permission policy called Cache-Filter, whose complexity is O(1), is proposed, aiming to store popular contents closer to users. Cache-Filter takes the content popularity into account and achieves the goal through the collaboration of on-path nodes. Extensive simulations are conducted to evaluate the performance of Cache-Filter. Leave Copy Down (LCD), Move Copy Down (MCD), Betw, ProbCache, ProbCache⁺, Prob(p) and Probabilistic Caching with Secondary List (PCSL) are also implemented for comparison. The results show that Cache-Filter performs well. For example, in terms of the distance to access to contents, compared with Leave Copy Everywhere (LCE) used by Named Data Networking (NDN) as the permission policy, Cache-Filter saves over 17% number of hops.

Role-Based Access Control(RBAC) is a flexible and policy-neutral access control technology. But, for large systems, managing roles, users, permissions and their interrelationships is a formidable task that cannot be centralized in a small team of security administrators. Using RBAC to manage RBAC provides addition히 administrative convenience. In this paper we demonstrate the implementation of one of the components of ARBAC99 which deals with permission-role assignment and is called PRA99. We implement it by using EJB component and use Oracle stored procedures to implement it.

The purpose of this paper is to capture the intuition that imperatives and deontic modal sentences are alike in some way but different in other ways, I show that imperatives and deontic modal sentences are alike in that both types of sentences have the modal force of deontic modality, but that they are different in that while imperatives make a contribution that there is an obligation or a permission issued by the speaker as an essential part of their meaning, deontic modal sentences assert the existence of an obligation or a permission in the current world.

In this paper, the Packet CDMA Reservation ALOHA protocol is proposed to support the multi-traffic services such as voice and videophone services with handoff calls, high-rate data and low-rate data services efficiently on the multi-rate transmission in uplink cellular systems. The frame structure, composed of the access slot and the transmission slot, and the proposed access permission probability based on the estimated number of contending users for each service are presented to reduce MAI. The assured priority to the voice and the videophone handoff calls is given through higher access permission probability. And through the proposed code assignment scheme, the voice service can be provided without the voice packet dropping probability in the CDMA/PRMA protocols. The code reservation is allowed to the voice and the videophone services. The low-rate data service uses the available codes during the silent periods of voice calls and the remaining codes in the codes assigned to the voice service to utilize codes efficiently. The high-rate data service uses the assigned codes to the high-rate data service and the remaining codes in the codes assigned to the videophone service. Using the Markov-chain subsystem model for each service including the handoff calls in uplink cellular systems, the steady-state performances are simulated and analyzed. After a round of tests for the examples, through the proposed code assignment scheme and the access permission probability, the Packet CDMA Reservation ALOHA protocol can guarantee the priority and the constant QoS for the handoff calls even at large number of contending users. Also, the data services are integrated efficiently on the multi-rate transmission.

The aims of this study were to examine the actual conditions surrounding the purchasing of online game items and Internet cyberspace items by adolescents the propensity of adolescents to consume these items, to determine the difference in the propensity for high and low consumption of these items among adolescents, and to investigate the characteristics of the adolescents who show a high propensity for the consumption of Internet items. The data for this study were collected from 483 adolescent consumers who were middle school and high school students in the city of Bucheon in Gyeonggi Province. The statistical methods used for the data analysis included frequency, percentage, standard deviation, t-test, and one-way ANOVA. The results of the present study can be summarized as follows. The majority(79.5%) of the students surveyed had had the experience of purchasing items. Most students(67.5%) had a rare frequency of buying ($1{\sim}2$ times in a period of 6 months or less). Nearly half (47.9%) of the students spent less than 1000 won per month on the item(s) purchased. Most of the students purchased items with their parents' permission, but 26.6% of the students bought the items without their parents' permission. Most of the characteristics of the items purchased, such as the major item purchased, payment method, amount purchased per month, average amount spent per buying experience, and whether or not they had their parents' permission differed according to gender, grade level, record, and monthly allowance. The level of propensity to consume the items was not high. The propensity of imitation consumption (1.96) was lower than that of impulsive consumption (2.38) and conspicuous consumption (2.45). Most of the buying characteristics, including the major item purchased, payment method, amount purchased per month, average amount spent per buying experience, parents' permission, grade level, and monthly allowance were different between the high and low propensity for consumption groups.

The fishing ground surrounding Wangdol-cho is not only overexploited by the littering of dilapidated fishing net and equipment, but also by fishermen's overfishing, surpassing optimum fisheries resources. In addition, increasing fishing efforts (number of fishing vessel and fishing net, etc) contribute to the deterioration of fishing ground, and it is urgently required that schemes to tackle the problems should be taken. To effectively address the problems as such, this paper aims to propose sustainable utilization and management scheme of fishing ground through classification of fishing ground surrounding Wangdol-cho as one area which is less than 50m deep, measuring $13.66km^2$ and the other, permission fishing area of Gill Net fishery, measuring $347.23km^2$. The analysis shows that, for the water area less than 50m deep, implementation from a short-term perspective includes autonomous management fishery by gill net and trap fishery. For the permission fishing area of Gill Net fishery, implementation includes limit on fishing period, real name system of fishing equipment and limit on fishing equipment. Implementation from a medium and long-term perspective includes limit on scuba diving, designation of underwater sightseeing zone, sea farming, facilities of surveillance, adoption of approval system for the permission fishing area of Gill Net fishery and introduction of report system for fishing.
