Purpose: The purpose of this study was to evaluate the effectiveness of 8 weeks smoking cessation program(SCP) developed by researchers. Method: One group pretest-posttest design was used in this study. The subjects were 88 male university students who consented to participate in the 8 weeks SCP. The SCP in this study consisted of a stop-smoking class, e-mail, SMS(short message service), cellular phone, internet cafe, displayed panel, and patch or acupuncture for quitting smoking. Korean version of questionnaire for nicotine dependency by Ahn et al.(2002), the smoking self-efficacy scale translated by Choi(1999) and subjects' opinion about the SCP were measured. The data were analyzed by using frequency, Chi-Square test, paired t-test and repeated measures ANOVA with SPSS WIN 10.1 Program. Results: 1) The rate of quitting smoking was 31.8% after 8 weeks SCP. 2) There was no significant decrease in the nicotine dependency score among smoking subjects after SCP. 3) There was a significant increase in self-efficacy after SCP. The mean score of self -efficacy in the quitting smoking group increased significantly, but did not significantly change in the smoking group. 4) The stop-smoking class was the most helpful among contents of the SCP. Contents of the SCP except for internet cafe were useful for quitting smoking in this study. Conclusion: The above results indicated that the 8 weeks SCP would be a helpful intervention to quit smoking for male university students.

Sand compaction pile (SCP) is a ground improvement method which is used to secure the stability of the soft ground by using a type of replacement pile filled with coarse grained material. The behavior characteristics of the SCP, which is frequently used for improving both the onshore and offshore ground, is governed by the ground condition, the installation method, and replacement ratio. Therefore, the stability of the SCP in terms of the bearing capacity and displacement needs to be evaluated considering both the design values and in-situ conditions of construction site. In this study, numerical analysis is carried out based on the conditions of 00 revetment construction site in South Korea where unexpected displacement occurred during construction of SCP. Based on the analysis results, the displacement of the revetment structure according to the replacement ratio of the SCP was compared to the result calculated from design formulas. The results showed that the lateral displacement can be exceeded the reference value from proposed criteria regardless of increased replacement ratio of SPC. It is also confirmed that the behavior of the structure according to the replacement ratio of SPC in not reflected in the existing calculation methods. Therefore, the stability of the SCP composite ground should be examined through the site inspection after the SCP construction.

The paper processed settlement analysis using Finite Elements Method(FEM). Because Stress Distribution Ratio has to be decreased, for settlement analysis of soft clay deposit improved by sand compaction piles(SCP). Back analysis was processed comparing the measured settlements of laboratory model tests and finite element analysis where the SCP treated area was assumed as mixed ground with clay deposit rather than being a composite ground. The paper proposes a methodology which employs a compression index($C_c$) for settlement analysis of soft clay deposit improved by sand compaction piles from the back analysis. This approach is applied to a field measurement case(A revetment founded on the SCP improved clay deposit with the replacement ratio of 45%).

In this paper, we studied the deployment of AIN(Advanced Intelligent Network) that was recommended by ITU-T there are five methods of deployment. Here we divided these methods into two types. One is the direct connection with SCP(Service Control Point) and IP(Intelligent Peripheral) via No.7 and the other is the indirect connection with SCP and IP Through SSP(Service Switching Point). First, we suggested the structure of AIN SSP and defined S/W functional blocks. Second, we proposed H/W functional extension for interaction with IP. On the basis of the suggested structure, we mathematically evaluated and simulated two types of the deployment of AIN. In the result, we knew that, in comparison with the indirect method, the direct method was effective.

In order to design accurately sand compaction pile (SCP) method with low replacement area ratio, it is important to understand the mechanical interaction between sand piles and clays and its mechanism during consolidation process of the composition ground. In this paper, a series of numerical analyses on composition ground improved by SCP with low replacement area ratio were carried out, in order to investigate the mechanical interaction between sand piles and clays. The applicability of numerical analyses, in which an elasto-viscoplastic consolidation finite element method was applied, could be confirmed comparing with results of a series of model tests on consolidation behaviors of composition ground improved by SCP. And, through the results of the numerical analyses, each mechanical behavior of sand piles and clays in the composition ground during consolidation was elucidated, together with stress sharing mechanism between sand piles and clays.

통신 기술의 발달로 인하여 고정망 뿐만 아니라 이동망에서도 지능망 서비스를 제공하는 것이 중요하게 생각되고 이에 대한 많은 연구가 진행중이다. 이 논문은 이동망에서의 지능망 서비스를 효율적으로 제공하기 위한 네트워크 모델을 제안한다. 제안하는 모델에서는 MSC/SSP와 SCP/HLR 사이의 두 가지 신호 구조를 고려한다. 이러한 모델에서 지능망 서비스를 제공하는 것이 효율적임을 보이기 위하여 먼저 VLR을 사용한 지능망 서비스의 제공 방안을 제시한 후, 두 가지 모델에서의 지능망 서비스 관리에 관한 성능을 분석해 보고자 한다. 이러한 방법은 SCP에 저장된 지능망 서비스 프로파일들을 VLR로 다운로드 하여 사용자로부터의 지능망 서비스 요청시에 SCP로의 연결을 줄이는 것이다. 제시한 방법은 SCP/HLR의 부하를 감소시켜 지능망 서비스 관리면에서 IMT-2000 보다 훨씬 더 나은 성능을 보인다.Abstract As the communication technology has been developed, it is necessary to provide the IN service in the mobile network as well as the fixed network and many researches are in progress. In this paper we propose the network model to efficiently provide IN service in the mobile network. There are two signaling architectures between MSC/SSP and SCP/HLR. To show that it is efficient to provide the IN service in the proposed model, we propose IN service provision method using VLR and analyze the performance of IN service management in two architectures. These methods are to download the IN service profiles that are saved in SCP to VLR and to decrease the connection to SCP when the user requests the IN service. The proposed methods show that the load of SCP/HLR is decreased and our method is better than IMT-2000 in the aspect of IN service management.

Sand Compaction Pile (SCP) is a soft-ground improvement technique used for not only accelerating consolidation but also increasing bearing capacity of soils. In this study, laboratory tests and 3-D finite element analysis were peformed to investigate the characteristics of load transfer in SCP with an emphasis on free-strain behavior of piles with low replacement ratios in the range of 30 to $50\%$. Through these focused tests and numerical analyses, we proposed a simplified method to analyze the load transfer characteristics of SCP in soft ground. Moreover, it was shown that estimated normal stresses in SCP using the proposed method were in a reasonable agreement with actual values.

In this study, the reliable and simple analysis method was proposed to predict the settlement characteristic of composite ground in stage of design and construction of sand compaction pile (SCP). Model parameters could be obtained by the optimization process based on genetic algorithm. In order to examine the proposed method, laboratory consolidation tests on the settlement characteristic of SCP composite ground were performed for various replacement ratio of sand such as 0 (no replacement), 20, 36, and 56%. The proposed model showed very good agreements with measured data in the relation of void ratio-log scaled stress and time-compression far each replacement ratio.

Supply Chain (SC) can balance demands with supply activities as executing Supply Chain Planning (SCP). The fluctuated demands, however, will break the balance between demand and supply. It means that the present SCP is useless in responding the changed demands. Thus it is necessary for SCP to be updated with changed demands. We call this procedure as Supply Chain Replanning. However, the existing measures for SC can not deal with the balance between supply and demand so that they can not detect effectively the timing of replanning. For this reason, a new performance measure, Balancing Point, is developed using momentum, a concept of Physics. It can treat the balance between supply and demand. Also, a replanning method based on Balancing Point is proposed. The proposed method is more effective than the existing replanning method, periodic replanning method and net inventory method.
