Objectives: To provide information on the safety of GST (Gami-Sasangja-tang), we carried out a single oral dose-increasing toxicity test of GST in beagle dogs.Materials and Methods: Six beagle dogs (three males and three females) were randomly assigned to two groups (experimental group: n=4, control group: n=2). The experimental group (two males, two females) was given oral doses of GST in increasing order (1,250, 2,500, and 5,000 mg/kg) at three-day intervals. After administration, the participants’ mortality, clinical signs, and body weight changes were monitored for two weeks. After two weeks, all dogs were sacrificed for autopsy.Results: Temporary vomiting was observed according to increasing dosage (n=1, 250 mg/kg; n=4, 2,500 and 5,000 mg/kg). Transient diarrhea was observed on the second and third dosing day (n=1, 2,500 mg/kg; n=2, 5,000 mg/kg). Temporary salivation was noted on the third dosing day (n=3, 5,000 mg/kg). Compound-colored stool was observed in all dogs fed the GST on all dosing days and also on the following days. We found no mortality and no abnormalities in the clinical signs, body weight, and gross findings in any of the dogs tested.Conclusions: The maximum tolerated dose was over 5,000 mg/kg for both male and female dogs.

Kill Chain is getting attention due to North Korea's recent nuclear test and missile launches and has emerged the need for an early build up. In order to build a materialized kill chain, you should review the unique kill chain to support operations effectively using various sensors and striking weapon system. Especially, you need a suitable network to reduce a reaction time against the enemy attack under joint operations environment etc. Currently there are many communication ways(e.g. data link, voice, video and text message) used in operations through satellite, wired and wireless and so on. Now, this paper contains analysis on various means for target information exchange which are used in the kill chain. And appropriate network of the kill chain for target information transmission is addressed to confirm feasibility of its alternatives, which is developed using AHP(Analytic Hierarchy Process). Finally, this paper is suggesting network and means of its building up for target information transmission of kill chain which can be implemented under the situation of joint battle field. 킬체인(Kill Chain)이 최근에 북한의 핵실험, 미사일 발사 등으로 인해 주목을 받고 있으며, 조기 구축의 필요성이 대두되고 있다. 킬체인 구축을 구체화하기 위하여 센서와 타격무기가 효과적으로 작전을 지원할 수 있도록 한국형 킬체인 네트워크에 대하여 검토해야 한다. 특히, 산악지역 및 해양을 포함한 짧은 종심의 합동전장 환경에서 적 위협으로부터 공격 대응시간을 단축할 수 있는 적합한 표적정보 전달 네트워크가 필요하다. 현재 작전에서는 다양한 유·무선 통신체계를 이용하여 음성, 데이터, 이미지, 문자 등을 작전에 활용하고 있다. 그러므로 본 논문은 킬체인에서 적용될 수 있는 표적정보 전달 네트워크에 대하여 분석하는 것이다. 그리고 네트워크의 정책적 대안에 대한 확증을 위해 AHP(Analytic Hierarchy Process) 기법을 적용하여 킬체인에 적합한 표적정보 전달 네트워크를 식별하였다. 이를 통해 합동 전장 환경하에서 적용 가능한 킬체인 표적정보 전달 네트워크 및 구축방안을 제시하였다.

Navy establishes the Naval Task Forces (TF) for many kinds of maritime operations. Then the TF in the maritime environment performs simultaneous component operations such as ASUW (Anti-Surface Warfare), ASW (Anti-Submarine Warfare), AAW (Anti-Aircraft Warfare),and assault operations. The TF consists of many tactical systems for the completion of missions -C4I, VOIP (Voice Over Internet Protocol), DMHS (Digital Massage Handling System), and TDLs (Tactical Data Links) such as LINK-11, 16, ISDL (Inter Site Data Link). When the TF executes naval operations to complete a mission, we are interested in the kill chain for the maritime operations in the TF. The kill chain is a standard procedure for the naval operations to crush enemy defenses. Although each ship has a procedure about a manual for ‘how to fight’, it leave something to be desired for the TF detailed kill chain currently. Therefore, in this paper, we propose the naval TF's kill chain to perform the naval operations. Then, the operational effectiveness of the TF in the kill chain environment is determined through operation scenarios of TDL system implementation. It is to see the operational information sharing effect to a data link model based on MND-AF OV 6c (statement of tracking operational status) in the maritime operations applied to TDL and is to identify improvements in information dissemination process. We made the kill chain of maritime TF for the effective naval operations. 해군은 다양한 해상작전을 수행하기 위해 해상기동부대(TF)를 구성한다. 해양 환경하에서 해상기동부대(TF)는 대함전(ASUW), 대잠전(ASW), 대공전(AAW), 그리고 상륙돌격 작전 등과 같은 동시·병행적으로 성분작전을 수행한다. TF는 임무완수를 위하여 C4I, 인터넷 음성전화(VOIP) 및 디지털 전보처리체계(DMHS)와 LINK-11, 16, ISDL 등과 같은 전술데이터링크를 갖춘 많은 전술체계들을 구성하고 있다. TF가 수명한 임무를 완수하기 위해 해상작전을 수행할 때, TF의 작전절차에 관심을 갖게 되었다. 작전절차는 적을 격파하기 위한 해상작전 수행을 위한 표준절차이다. 각 함정은 ‘어떻게 싸울 것인가’에 대한 매뉴얼에 교전절차는 갖고 있지만, 현재 TF의 상세한 작전절차는 미흡하다. 따라서, 본 논문에서 우리는 효과적인 해상작전 수행에 필요한 작전절차를 제안한다. 그런 작전절차 환경에서 TF의 작전 효과성은 전술데이터링크 운영의 작전 시나리오를 통해 결정하고자 한다. 전술데이터링크를 적용한 해상작전에서 데이터 링크 기반으로 국방 아키텍처프레임워크(MND-AF) OV-6c(운용상태 추적 기술서)에서 작전정보 공유효과를 살펴보고, 정보 전파과정 개선을 식별하는 것이다. 본논문에서는 효과적인 해군작전의 해상 TF를 위한 작전절차 모델을 제안하였다.

The main objective of this study was to investigate the effects of physical self-efficacy of adolescents who joined a school sports club on school violence bullying behaviors. For this purpose, the subjects in this study were 276 students in junior high schools and 154 students in high schools located in Cheonan-si and Gongju-si, Chungcheongnam-do in 2013. Questionnaires on physical self-efficacy factors used in studies by Moon Jin (2008), Seo Cha-Won (2012) and Park Yoon-Kee (2013) and on school violence bullying behavior factors by Do Gie-Bong (2007), Park Jae-Suk (2008), Kim Min-Jeong (2010) and Lee Se-Mi (2013) were used as a research tool with the addition of modification and supplement after verifying the suitability of the component content and items according to expert advice for the purposes of this study. The collected data were computerized using SPSS Statistics were analyzed by applying a descriptive statistical analysis, one-way ANOVA and multiple regression analysis for analytical purposes. The following results were obtained: First, this study examined differences in the physical self-efficacy according to the demographic characteristics. In gender, female students showed a significantly higher physical self-presentation confidence, a sub-factor of the physical self-efficacy, than male students. However, there was no significant difference in perceived physical ability, another sub-factor. In school level, the junior high schools showed higher perceived physical ability and physical self-presentation confidence than the high schools, but they were not statistically significant. Both in perceived physical ability and physical self-presentation confidence, the physical self-efficacy according to the type of sports club was high in individual, interpersonal and group exercises, in descending order, but they were not statistically significant. Both in perceived physical ability and physical self-presentation confidence, the physical self-efficacy according to the physical education grade was high in lower, middle and upper classes, in descending order, but they were not statistically significant. Second, this study examined differences in the school violence bullying behaviors according to the demographic characteristics. In gender, male students showed a higher harassment, verbal-psychological abuse, and bullying, sub-factors of the school violence bullying behaviors. In particular, there were significant differences in the verbal-psychological abuse. In school level, the high schools showed higher harassment and verbal-psychological abuse than the junior high schools as a difference in other school violence bullying behaviors, but they were not statistically significant. The junior high schools showed higher harassment than the high schools, but this was also not statistically significant. Both in the harassment and verbal-psychological abuse, the differences in the school violence bullying behaviors according to the type of sports club were high in individual, interpersonal and group exercises, in descending order, but all of them were not statistically significant. In the harassment, the differences in the school violence bullying behaviors were high in upper, lower and middle classes, in descending order. In the verbal-psychological abuse, the differences in the school violence bullying behaviors were high in middle class and showed the same value in upper and lower classes, but all of them were not statistically significant. Third, this study examined the effects of the adolescent physical self-efficacy on the school violence bullying behaviors. The results showed that the physical self-representation confidence a sub-factor of the physical self-efficacy had a statistically significant effect on the harassment verbal-psychological abuse and bullying. Although the perceived physical ability as another factor had a significant effect on the harassment verbal-psychological abuse and bullying, it was not statistically significant. Based on the above conclusions, the gender showed significant differences in the adolescent physical self-efficacy and school violence bullying behaviors, and the school violence bullying behaviors also increased in the proportion of the physical self-presentation confidence, a sub-factor of the physical self-efficacy. It is considered that this has caused an unexpected negative result the school violence bullying behaviors due to the absence of the system that students can positively release their passionate energy in the current school system. Therefore, it is considered that schools and related organizations should make efforts from various perspectives so that adolescent passion strength and energy from the physical self-efficacy can be released not in the school violence bullying behaviors but in healthy and desirable physical activities and sports participation as a method to reduce the school violence bullying behaviors of adolescent students with high physical self-efficacy.
