Recently SMEs(small and medium enterprises) in Korea have experienced severe labor shortages. In particular, college graduates avoiding SMEs are widely spotted. According to previous studies, the main causes of the evasion by college graduates are the inferior working environment and low wages. Some studies also state that SME workers experience discrimination. However, most studies have focused only on unemployment issues of the young graduates. In this research, the results of follow-up surveys on the employment status and job conditions of recent college graduates was linked as a panel data, and the performance of the graduates was analyzed. Based on the analysis, we found college graduates who are employed SMEs are likely to have their initial career fixed to the SMEs. Second, the job separation records of the young SME workers does not show positive labor market performances such as upward movements or wage increases, and the process itself turned out to be entailed frequent separation. Third, the inferior wage level at SMEs and the fact that this effect is cumulatively amplified has been a key factor for evading SMEs. Thus, it is difficult to say that the early-stage careers in SMEs are constructive in future career development. On the contrary, the early careers at SMEs result in lower labor market outcomes, and frequent job separation.

The discovery and understanding of antigenic proteins are essential for development of a vaccine against malaria. In Plasmodium falciparum, Pf92 have been characterized as a merozoite surface protein, and this protein is expressed at the late schizont stage, but no study of Pv92, the orthologue of Pf92 in P. vivax, has been reported. Thus, the protein structure of Pv92 was analyzed, and the gene sequence was aligned with that of other Plasmodium spp. using bioinformatics tools. The recombinant Pv92 protein was expressed and purified using bacterial expression system and used for immunization of mice to gain the polyclonal antibody and for evaluation of antigenicity by protein array. Also, the antibody against Pv92 was used for subcellular analysis by immunofluorescence assay. The Pv92 protein has a signal peptide and a sexual stage s48/45 domain, and the cysteine residues at the N-terminal of Pv92 were completely conserved. The N-terminal of Pv92 was successfully expressed as soluble form using a bacterial expression system. The antibody raised against Pv92 recognized the parasites and completely merged with PvMSP1-19, indicating that Pv92 was localized on the merozoite surface. Evaluation of the human humoral immune response to Pv92 indicated moderate antigenicity, with 65% sensitivity and 95% specificity by protein array. Taken together, the merozoite surface localization and antigenicity of Pv92 implicate that it might be involved in attachment and invasion of a merozoite to a new host cell or immune evasion during invasion process.

To perform the engagement level simulation between the underwater vehicle model and the surface model those are constituted with various systems/ sub-systems, we implemented four different federates as a federation according to the IEEE 1516 HLA (High Level Architecture) protocol that is the international standard in the distributed simulation. Those are CFCS (Command and Fire Control System) federate, motion federate, external entities (torpedos, countermeasure and surfaceship) federate, and visualization federate that interacts with OSG (Open Scene Graph)-based visualization rendering module. In this paper, we present the detailed method about the model constitution for discrete event simulation in the distributed environment. For the sake of this purpose, we introduce the DEVS (Discrete Event System Specification)-HLA-based modeling method of the CFCS federate that reflects not only the interations between models, but also commands from user and tactics manager that is separated from the model. The CFCS federate makes decisions in various missions such as the normal diving, the barrier misision, the target motion analysis, the torpedo launch, and the torpedo evasion. In the perspective of DEVS modeling, the CFCS federate is the coupled model that has the tactical data process model, command model and fire control model as an atomic model. The message passing and time synchronization with other three federates are settled by the $m\ddot{a}k$ RTI (Runtime Infrastructure) that supports IEEE 1516. In this paper, we provides the detailed modeling method of the complicated model that has hierarchical relationship such as the CFCS system in the submarine and that satisfies both of DEVS modeling method for the discrete event simulation and HLA modeling method for the distributed simulation.

The economic cooperation between the South and North Koreas is a very important issue for the unification and economic development of both Koreas. In order to reach a successful economic cooperation, there is a need to coordinate the differences of the two countries before unification. The economic cooperation and the cooperation in other sectors will be followed by the entire unification. It is necessary to prepare a mechanism that could peacefully solve the conflicts and disputes that could arise during the actual process of cooperation, which will secure stable investments and trades. The study on the possibility of introducing the arbitration system as a conflict solving mechanism between the two Koreas is a very important subject, and the basis of this study is on the examination of the arbitration laws of North Korea. Therefore, the study on the efficiency of the North Korean arbitration laws on foreign economy is studying the possibility of a systematical solution to economic conflicts between the South and North Koreas. The problems and possible solutions of the North Korean foreign economy arbitration laws are summarized as follows. First, juridical cooperation system for both South and North courts of justice needs to be set up to smoothly carry out the main procedures. Mutual correspondence and telecommunication needs to be guaranteed, also remittance and the movement of goods shall precede. Second, the free liquidation of businesses by unit and the individual and independent management of wealth of the North Korean economic bodies, organizations and businesses shall precede to independently liquidate wealth and thus make arbitration possible. Third, amendments in the North Korea's foreign economy arbitration law shall be made to some parts of regulations on arbitration agreements and specific contents of written arbitration agreements to avoid conflicts regarding arbitration agreement. Fourth, the members of the North Korean arbitration committee shall impartially manage the committee only without taking the role of arbitrator, and the clause that allows the North Korean committee to nominate the arbitrator shall be erased. In case an agreement regarding the number of arbitrators is not reached, the three arbitrators general rule shall be applied. In case of requests from any of the parties, a third country arbitrator nomination shall be guaranteed. Also, the requested arbitrator by the party shall be nominated with the cooperation of the court. Fifth, the trial in case of non-appearance or written trial shall be added to the North Korean law in to prevent intended negligence or evasion. Sixth, regulations regarding the court's investigation of evidence shall be added to the North Korean law to make fair arbitration possible in case that government power is needed in order to investigate evidence. Seventh, provisions regarding majority decision shall be added in the North Korean law in the impossibility of unanimous decisions, and the certified system in the arbitration committee official text shall be erased to prevent arrogation and assure the power of the decision made by the arbitration government. Eighth, as "the wrong decision approved" reason for cancellation of arbitration in the North Korean law includes the content of the decision made by the arbitrator could lead to uselessness of arbitration, amendment will be necessary to limit it to legitimacy of the arbitration agreement and wrong procedures. It is hoped that this thesis will be of important use in understanding the issues on the workability and the solutions to the South and North Koreas' arbitration that could be presented during the negotiations for the countries' economic cooperation.
