The purpose of this study is provide appropriate arms control measures between South and North Koreas by comparing and analyzing the former proposals and agreements in the past and the current Moon Government's approach representing the 9.19 military agreement. For this, I established the most appropriate framework for analysis through comparing and analyzing the arms control theories. The policies of the past governments and of the current Moon Jae-in government are analyzed. The most highlighted characteristic was that the arms control policies were projected by not from the military confidence, but political confidence building measures or both concurrently. In conclusion, I suggested the strategies of projecting confidence building measures and arms control or disarmament in the process of projecting the peace settlement. Nonetheless, the most important point is that the policies of arms control and unification should be pushed ahead complementally.

This paper concerns a case study on the design concept, analysis, construction methodology of a subway tunnel excavated in the soft ground beneath an existing building where the distance between the bottom of the building and the crown of the tunnel is separated by about 3 meters only. The silot tunnels are excavated in advance, and side reinforced-concrete walls are installed. Then, main tunnels are excavated with ring cut method. The steel ribs are installed and supported by the side walls made in advance. Between the steel ribs and the side walls, the screw jack is installed to apply prestressing so that settlement can be controlled at minimum. Various in-situ seasurements are made and compared with computed values obtained by numerical methods. By choosing this underpinning method with very caraful construction control, tunnelling projects could be finished successfully without having any damage to the building located very closely to the tunnel crown.

Utilizing of the geotextile container shows several advantages such as standardized construction, factory manufactured products, the control of quality, workability, and economical point of view. Recently this technique can be applied to rehabilitate the loss of rail roadbed due to the heavy rainfall. In this study, a large-scale laboratory test were conducted with simulation of static performance on the geotextile container reinforced rail roadbed. Based on the laboratory test results, the vertical pressure distribution with respect to the depth, and settlement of rail roadbed were measured and compared test results between geotextile container reinforced case and unreinforced case. Thus, the effectiveness of reinforcement was evaluated in terms of its performance and stability.

In a case of an example in Korea, some areas of Yangsan near Busan which exist on soft ground with aquifer, showed us some difficulties of the preparing for housing site and earth structures. From these experiences, recently, the development and research of technology is getting increased, which minimize the influence to the environment from construction work, which is in an agreement with eco-friendly construction in terms of the reasonable processing of ground water. On this case study, one area of Japan that has many site on soft ground with aquifer, is introduced as the reasonable processing of ground water. The applications of the technology for ground water in Korea are discussed.

There are many reasons for occurring vibration when trains run on the railway, but the typical vibration are occurring when the trains run on the elevated Railway bridge. For the settlement of the problems form the vibration, it must be performed to analyze the effect of the vibration to human bodies and adjacent area. and to establish the countermeasures. In this paper, we analyzed the effects of the vibration to the bridge itself and to adjacent structures by measuring the vibration of Yong-Dang Elevated Railway Bridge on Jeolla Line and adjacent area.

the Effect of steel pipe reinforced multi-step grouting(SPRG) technique to inrove the ground far ahead of the excavation face was investigated by means of numerical analysis. It was found taht the nonlinear 3-D FEM program performed well to evaluate the usefulness of the SPRG technique in soft ground tunnelling, and about 20% of settlement control in this particular case possible. Therefore in urban subway tunnel construction, the New Austirial Tunnelling Method can be satisfactorily applied even in poor ground conditon with aid of the SPRG technique.

Objectives : The authors performed this study to further understand Saam acupuncture method in an aspect of formation process. Methods : We were finding Saam's idea in a preface of the book. And we analyzed Saam acupuncture patterns to understand their formation. Results & Conclusion : We assume that Saam acupuncture patterns has formed over time. We were able to split their patters into three phases. That is Primitive-phase, Basic-phase and Practical-phase. We think they are traces of Formation Process. In the first, Saam found DongHaeng-acupoints that have in common Five Element between the five viscera and acupoint. And then, he compounded other meridian's DongHeng-acupoints to control self meridian. Finally acupoints of self meridian were added.

ITS(Intelligent Transport System) as things are used for Broadcast service using TDMB/TPEG/NAVI rather than personal seamless service. It is attaching weight to Traffic information gathering, Charging, Settlement service. This research is applied to improve DCCP(Datagram Congestion Control Protocol) which has function as protecting data and preserving message boundary. The improving method is like that we solve data trust in UDP because Connection and Transmission overhead in UDP is less than in TCP. We fix the data loss which is generated from unordered delivery section of IP base wireless service by using DCCP protocol. We guarantee of connection with OBE(On-Board Equipment) and reliance about transmission of data by complement to mapping table and multi-hoping. Finally, We evaluate the performance about transmission of IP based data. We constructed a test-bed near research center for this test.

The purpose of this study was to evaluate the effect of a sex education program on the aged's sex perception and the life satisfaction. It was the non-equivalent control group pre-post test design, the number of subjects was 65 people as the experimental group and 70 people as the control group over 65 the aged. The program was conducted for 80 minutes a time for 6times of the N settlement house in P city from August 25 to September 16 in 2011. The study tool which was developed by Lee(1999) and revised by Jeong(2007), was used to measure the sex perception. The life satisfaction was measured by Naugarten(1961) and modified by Kim(2002). The date were analyzed as SPSS Win 17.0, the percentage, t-test, and the hypothesis was analyzed as t-test. The experimental group got higher scores on the sexual percetion(t=3.816, p<.001) and the life satisfaction(t=4.594, p<.001). This program is for generalized that must be performed in a repeat and comprehensive study with the many aged.
