This research was carried out to investigate the corrosion prevention effect in the water distribution system by galvanized zinc-brass pipe which is using potential between brass and zinc. As a result of this study, pH and conductivity of influent were constant in spite of its installation, and it was difficult to estimate the effect of the installation with temporary increased and reduced concentration of Zn and Fe ions, respectively. However, since the corrosion rate of the steel coupon with galvanized zinc-brass pipe was relatively low, it has an effect of inhibiting corrosion.

This paper reports on a realtime OS based master-slave configuration robot control system for laparoscopic surgery robot which enables telesurgery and overcomes shortcomings with conventional laparoscopic surgery. Surgery robot system requires control system that can process large volume information such as medical image data and video signal from endoscope in real-time manner, as well as precisely control the robot with high reliability. To meet the complex requirements, the use of high-level real-time OS (Operating System) in surgery robot controller is a must, which is as common as in many of modem robot controllers that adopt real-time OS as a base system software on which specific functional modules are implemened for more reliable and stable system. The control system consists of joint controllers, host controllers, and user interface units. The robot features a compact slave robot with 5 DOF (Degree-Of-Freedom) expanding the workspace of each tool and increasing the number of tools operating simultaneously. Each master, slave and Gill (Graphical User Interface) host runs a dedicated RTOS (Real-time OS), RTLinux-Pro (FSMLabs Inc., U.S.A.) on which functional modules such as motion control, communication, video signal integration and etc, are implemented, and all the hosts are in a gigabit Ethernet network for inter-host communication. Each master and slave controller set has a dedicated CAN (Controller Area Network) channel for control and monitoring signal communication with the joint controllers. Total 4 pairs of the master/slave manipulators as current are controlled by one host controller. The system showed satisfactory performance in both position control precision and master-slave motion synchronization in both bench test and animal experiment, and is now under further development for better safety and control fidelity for clinically applicable prototype.

한반도의 특수성을 고려한 한국의 군사전략 발전방안

송승준 ( Seung Joon Song ) 미래군사학회 2013 한국군사학논총 Vol.2 No.1

Considering the changes of Security environment such as the change of re cent war trend, modern warfare and ROK-Military Reform etc, these days a re debating for the developing of ROK-Milirarys strategy. The core of Requ irements according to following like these ; Firstly, Korea must establishes on the military strategy with playing a leading role, considering the changes of recent war tendency and ROK-Military Reform(reducing the scale of milit ary, reforming a technique forces), and the wartime OPCON Transition. Secondly, The new strategy must be made considering that a deceive war has purposes and objectives, How long the executing period is. where a dec eive war takes place, What is the way(means and ways=Art of war), What are the available assets for the deceive war. And according to the Art of war on the base of these military strategy must be developed and ROK Military m ust be trained. But Investigating the our statues, there are a lot of problems on linking with Military strategic concepts - Doctrines - Construction of Mil itary power - Education & Training. The ways of New ROK-Military Strategy insisting on this study have to i nclude the components( those are Purposes and Objectives, Means and Ways (Art of war), operating Military assets) of planning Military Strategy reflecting the Korean peninsula special environment and the changes of recent war tre nd. and I described as ; Firstly, Establishing new strategic purpose and obje ctive are similar the former one. the different focus is that this study is addi ng Defence of the border with other nations on the former concepts, such as the Occupation on north Korean area & Reunification and removing the nort h korean government. Campaign on the concepts of this study will be separa ted with several one, not one campaign. and Each campaign must define each purpose & objectives. Secondly, On the level of Art of war, When we consider the tendency of recent war, modern warfare, Available military assets, Reform of ROK-Milit ary, Environment of time and space, etc, this study insists that the campaign of Korean peninsula have to change several campaigns, improving that now Korean peninsula be defined as one campaign and separated with Main opera tions in the one. there are some reasons that After turning over the wartime OPCON, Korean military must carry out some decisive operations as a statu s of main operator with the wartime OPCON on the war, so have to fight wit h substantial available military assets. and the Art of war must be made con sidering those. For that reason, this study suggested that It is desirable that the campaign for Defense when north korea attack to the south korea have to be divided over 2 campaigns, and the campaign for seizing north-korea ar ea and reunification when we counter attack to the north-korea. have to be divided over 3 campaigns. On the focus of Military assets, The way of head for building new Military strategy have to meet next two demands ; First, Military assets have to be constructed on the bases of the Art of War of each campaigns. Because Art of war is quite different with Time and Space, and at this time Military asset s to be operated are different. Thus, The military assets operated at Now co ntacting area with enemy(the area of DMZ and FEBA), Deep area of north k orea, and The border with other nations have to be fixed and constructed ac cording to each Art of war concepts. Second, Our neighboring countries are Strong nations that can be heading for world hegemony. Our nation which is small nation can not build all of the military power requested for winning aga inst Our neighboring countries. Thus, we have to fix the appropriate constru ctive goal of the military power. and Those are linked with nation policy, nat ion strategy, military strategy. For overcoming the shortage of military asset s, those have to be reflected on the building plans of military power conside ring those possibility, and those can be arranged at the level of national stra tegy. At this time, we have to develop the plan that the shortage of military power make up with ally-nation``s military powers.

M. Lipsky일선관료제이론에 근거한 전문교과교사의 NCS학습모듈 대응기제 분석

송승준(Song Seung-jun) 학습자중심교과교육학회 2021 학습자중심교과교육연구 Vol.21 No.10

목적 본 연구는 단위학교 일선교사들이 NCS(National Competency Standards; 국가직무능력표준)학습모듈로 교육과정을 운영하면서 겪게 되는 반응과 이에 따른 대응기제를 Lipsky의 일선관료제이론으로 분석한 것이다.방법 NCS학습모듈 대응 설문 조사(단위학교 전문교과 교사의 NCS 학습모듈 편성운영 및 현황실태와 대응 조사), NCS학습모듈 대응 심층 면담과 코딩하기(Lipsky의 일선관료이론으로 NCS학습모듈 편성운영과 대응 취합 및 분석), NCS학습모듈 대응기제 분석(NCS학습모듈 정책집행방향 제안) 등의 순서로 진행 되었다.결과 첫째, 정책결정과 정책집행은 그 성질 면에서 본질적인 차이가 없다는 것을 알 수 있었다. 정책결정기관과 정책집행기관인 단위학교나 일선교사 상호간에는 지금보다 개방적이고 순환성을 가질 수 있는 NCS학습모듈을 운영해야 한다. 둘째, Lipsky의 일선관료제이론이 본 연구에서 재정의되는 부분은 다음과 같다. Lipsky는 역할재정의(changing role expectations)에서 일선교사(관료)들은 정작 요구되는 일은 회피하고 자신들이 원하는 역할만 수행하는 결과를 가져올 수 있다고 우려했다. 그러나 본 연구조사에서 일선교사들은 NCS학습모듈 교육과정 편성운영에 있어 회피나 역할기피로 반응하고 대응하는 것이 아니었다. Lipsky의 역할재정의와는 다르게 NCS학습모듈 적응 메커니즘을 형성하고 있었다. 셋째, 일선교사들은 교육과정의 재량권으로 정책집행의 순응을 지향하고 있었다. 그 순응의 방법은 재량권에 의한 단순화와 정형화라고 분석 된다. Lipsky가 일선관료제이론에서 일선교사(관료)의 직무수행에 있어 상당한 재량권이 중요하다는 사실이 본 연구를 통해서도 확인할 수 있었다. 일선교사들은 재량권을 통하여 NCS학습모듈의 부족한 부분에 신속하게 대응하고 있었다.결론 본 연구는 NCS학습모듈을 운영하고 있는 단위학교 일선교사를 연구대상으로 Lipsky의 일선집행관료제이론을 통한 반응과 대응기제를 분석했다. 연구과정에서 Lipsky의 일선관료제이론과 일선교사들의 정책집행에서 분석된 반응이 재정의된 경우도 있었다. 왜 이러한 대응기제가 나타나는지는 후속연구를 통하여 분석해 볼 필요가 있다고 본다. 본 연구가 일선교사(관료)의 NCS학습모듈 정책집행과정을 연구하는데 조금이나마 도움이 될 수 있기를 바란다. Objectives This study analyzed the reactions experienced by school teachers in unit school while operating the curriculum with the learning module of National Competency Standards (NCS), and the incidental response mechanism with Lipsky s Street-level Bureaucracy. Methods This study was conducted in the order of 1) the NCS learning module response survey (organization and operation, current status, and response survey of unit school vocational subject teacher s NCS learning module), 2) in-depth interview and coding for NCS learning module (organization, operation, and response collection and analysis of NCS learning module with Lipsky s Street-level Bureaucracy), and 3) analysis of NCS learning module response mechanism (NCS learning module policy implementation direction proposal). Results First, it was found that there was no fundamental difference between policy making and policy implementation in terms of their nature. The NCS learning module should be operated that can be more open and circulatory than now between the policy-making body and the policy-implementation (each unit school) or between school teachers.Second, Lipsky s Street-level Bureaucracy is redefined in this study as follows. Lipsky was concerned that in changing role expectations, school teachers (bureaucrats) were avoiding what was really required and that it could result in only performing the roles they wanted. However, in this study, school teachers did not react and respond with avoidance or role avoidance in organizing and operating the NCS learning module curriculum. Unlike Lipsky s role redefinition, the NCS learning module adaptation mechanism was formed. Third, school teachers were aiming for conformity with policy implementation with the discretion of the curriculum. The method of conformity is analyzed as simplification and formalization by discretion. As in Lipsky s Street-level Bureaucracy, this study also confirmed that considerable discretion is needed in the performance of school teachers (bureaucrats). School teachers were responding quickly to the shortcomings of the NCS learning module through their discretion. Conclusions This study analyzed the responses and the response mechanisms through Lipsky s Street-level Bureaucracy, targeting the school teachers of the unit schools operating the NCS learning module. In the course of research, there were cases in which Lipsky s Street-level Bureaucracy and the reactions analyzed in school teachers policy implementation were redefined. It is thought that it is necessary to analyze why such a response mechanism appears through follow-up studies. It is hoped that this study will be of any help to study the policy implementation process of the NCS learning module by school teachers (bureaucrats).

The fuzzy self-tuning PID controller is a PID controller with a fuzzy logic mechanism for tuning its gains on-line. In this structure, the proportional, integral and derivative gains are tuned on-line with respect to the change of the output of system under control. This paper deals with two types of fuzzy self-tuning PID controllers, rule-based fuzzy PID controller and learning fuzzy PID controller. As a medical application of fuzzy PID controller, the proposed controllers were implemented and evaluated in a laparoscopic surgery robot system. The proposed fuzzy PID structures maintain similar performance as conventional PID controller, and enhance the position tracking performance over wide range of varying input. For precise approximation, the fuzzy PID controller was realized using the linear reasoning method, a type of product-sum-gravity method. The proposed controllers were compared with conventional PID controller without fuzzy gain tuning and was proved to have better performance in the experiment.

국방 동원예비군 원격교육체계 발전방향

송승준(Seungjun Song) 육군사관학교 화랑대연구소 2011 한국군사학논집 Vol.67 No.2

The purpose of this study is to create a concept of how to construct mobilization reserve’s distributed learning system and to provide ways of its development. Thus, I analyzed DMIS(Defense Mobilization Information System) that is currently operating and presented ways of the education for upcoming future. The key points of this paper are as follows; DMIS can't use the learning system in order to meet capabilities needed for Korean RMA. To conduct it through the multimedia, including Intranet, Internet, IPTV and KFN, MND will have to construct four types of LMS; Instructor-LMS, Student-LMS, Management-LMS, Planner-LMS. It also will have to radically enhance DMIS’s capabilities, and carefully consider what an integrated exclusive or ganization is established and its efficiency and effectiveness in terms of the distributed learning, determining each location of LMSs according to grouping members by regions. In addition, the contents must be based on the Data(Contents)-Standardization Project, which is leaded by MND, to re-use them. It has to develop a Data-Exchange-System and its security system in order to protect and utilize various media and is compatible with each media. To build these systems, We need to comprehend the bases of the systems, create concepts, organize the distributed learning services-group, develop contents, and improve operating methods. Finally, All projects should proceed based on ROC process, which is the way of HI-LOW.

북핵문제해결을위한 중국의 역할변화에 관한 연구 -한반도에 대한 중국의 정책변화 유도를 중심으로-

송승준 ( Seung Jun Song ) 미래군사학회 2012 한국군사학논총 Vol.1 No.1

This study is focused on the way of changing Chinese foreign and diplomatic policies toward Korean peninsula. Particularly, it specifies on the China``s role regarded to the No -rth Korea``s nuclear issue. China has took three ways of nuclear policies to North Korea: e.g., ‘support,’ ‘mediation,’ and ‘sanctions.’ But China has tended to have policies of supp -ort and mediation rather than sanctions against North Korea``s military behaviors Thus, international efforts of sanctioning North Korea have been failed. It is because sustaining the North Korean regime generates benefits for the China``s national interests. By reinforcing China-North Korea economic relations, China can increase its influence to North Korea and in Northeast Asian politics as well Therefore, South Korea has to establish better strategies for inducing China``s foreign and diplomatic policy changes toward the Korean peninsula, especially positive to South Korea. The possibility of changing policies is dependent upon China``s national interests. This paper suggests ways of changing China``s role from the perspective of geo-strategic strategies to geo-economic ones.
