Abstract: An LIBS module includes a cover having a first optical channel through which a laser beam passes and a second optical channel through which plasma emission light passes therein; a first optical system placed in the first optical channel; and a second optical system placed in the second optical channel. A clamp with a coupling hole through which a predetermined pipe may pass is formed in the cover, and the coupling hole is placed in a region where an extension path of the first optical channel and an extension path of the second optical channel cross. The clamp includes a first clamp branch and a second clamp branch, and while a first segment of the pipe is coupled to the coupling hole, the first clamp branch and the second clamp branch are tightened to each other to couple the pipe and the LIBS module to each other.

Abstract: Disclosed is a quantum cryptography key distribution system. A receiving device of the system includes: a first single-photon detector outputting a data signal including a time-bin encoding pulse indicating a quantum signal; and a TDC receiving a predetermined reference timing signal and the data signal. The TDC is configured to determine a state of a time-bin qubit indicated by the time-bin encoding pulse based on a time difference between a first generation time point of a reference pulse included in the reference timing signal, and a second generation time point of the time-bin encoding pulse generated after the first generation time point.

Abstract: Disclosed is an analysis device including a microfluidic chip that generates a droplet, a machine vision that captures a first point of the microfluidic chip, and a LIBS module that irradiates a second point of the microfluidic chip with laser. When a droplet is detected in an image captured by the machine vision, the LIBS module is driven to irradiate laser. The first point and the second point are points where the generated droplet can be observed.

Abstract: Disclosed is a cloud development platform system including: a project server including an issue management unit managing histories of all issues which occur in the middle of performing a development project; a project management server including a project replication unit; and an issue management server providing a first issue selected by a developer of the development project among all issues which occur in the project server in the middle of performing the development project to the project management server. The project replication unit is configured to generate a replicated server replicating all data of an OS of the project server generating the first issue and an upper layer of the OS.
