This article explores a commonly ignored aspect of Japan–North Korean relations: the Japanese factor in the making of Korean socialism. Korea was indirectly influenced by the Japanese Jiyuminken Movement, in the 1910s–1920s serving as a stepping-stone for the creation of a Japanese Communist Party. Wartime mobilization policies under Japanese rule were continued and expanded beyond the colonial era. The Juche ideology built on tendencies first exhibited in the 1942 Overcoming Modernity Conference in Japan, and in the 1970s some Japanese leftists viewed Juche as a humanist Marxism. Trade between Japan and North Korea expanded from 1961 onwards, culminating in North Korea’s default in 1976, from which point on relations soured between the two countries. Yet leaders with direct experience of colonial rule governed North Korea through to the late 1990s.

Long life education have many mention that made us confused to separate between formal and non-formal education. It need to give clear explanation likely on concept, program and so on. This article simplify explore one by one and side by side anything that it was easier for anyone. Especially on concept, long life education must have a permanent understanding so that decreasing mistake interpretation. After agree on it, it may a program can be ordered based on field reality. Like a stepping stone, the program must be done on and on as long as alive. Someone may be not realized if their own was living in educational program. So the program is depend on time and selves as a subject education goal. Then by time, long life education can implies to school, social, institutions, individual, and anything matter connected with learning process.

Self-replicating robot systems (SRRSs) are a new prospective paradigm for robotic exploration. They can potentially facilitate lower mission costs and enhance mission capabilities by allowing some materials, which are needed for robotic system construction, to be collected in situ and used for robot fabrication. The use of a self-replicating robot system can potentially lower risk aversion, due to the ability to potentially replenish lost or damaged robots, and may increase the likelihood of mission success. This paper proposes and compares system configurations of an SRRS. A simulation system was designed and is used to model how an SRRS performs based on its system configuration, attributes, and operating environment. Experiments were conducted using this simulation and the results are presented.

AbstractTransportation problem (TP) is a popular branch of Linear Programming Problem in the field of Transportation engineering. Over the years, attempts have been made in finding improved approaches to solve the TPs. Recently, in Quddoos et al. (Int J Comput Sci Eng (IJCSE) 4(7): 1271–1274, 2012), an efficient approach, namely ASM, is proposed for solving crisp TPs. However, it is found that ASM fails to provide better optimal solution in some cases. Therefore, a new and efficient ASM appoach is proposed in this paper to enhance the inherent mechanism of the existing ASM method to solve both crisp TPs and Triangular Intuitionistic Fuzzy Transportation Problems (TIFTPs). A least-looping stepping-stone method has been employed as one of the key factors to improve the solution quality, which is an improved version of the existing stepping-stone method (Roy and Hossain in, Operation research Titus Publication, 2015). Unlike stepping stone method, least-looping stepping-stone method only deals with few selected non-basic cells under some prescribed conditions and hence minimizes the computational burden. Therefore, the framework of the proposed method (namely LS-ASM) is a combination of ASM (Quddoos et al. 2012) and least-looping stepping-stone approach. To validate the performance of LS-ASM, a set of six case studies and a real-world problem (those include both crisp TPs and TIFTPs) have been solved. The statistical results obtained by LS-ASM have been well compared with the existing popular modified distribution (MODI) method and the original ASM method, as well. The statistical results confirm the superiority of the LS-ASM over other compared algorithms with a less computationl effort.
