The present invention is directed, in part, to a system and methods for human resources management and efficient, online and mobile guidance on assisting job seekers in locating and securing job opportunities. More specifically, the present invention relates to a system and methods for performing substitute fulfillment, including identifying acceptable substitute employees/professionals, job opportunity review, real time employee availability, skill set review for employers/clients, appointment scheduling and establishing network connections amongst employers/clients and employees/professionals for both current and future job opportunities. Even more specifically, the present invention relates to building experience hours through successive work experience, establishing network connections and securing employment through historical connections among subscriber users and in optimizing staffing to accommodate for peak and non-peak business hours. Further, the present invention provides methods and a system for optimizing scheduling for available employment shifts through geolocation and internet sources.

An object of the present invention is to provide apparatuses and methods, in which solation of a mixed liquid can be allowed to progress under sufficiently controlled conditions with the mixed liquid being effectively cooled, to thereby industrially produce a homogeneous sol, and then sol-gel transition with a phase separation process can be induced, to produce a gel having a co-continuous structure of a skeleton phase and a solvent phase and to produce a silica porous body having macropores. According to one embodiment of the present invention, there is provided a sol producing apparatus (1) that produces a sol for use in production of a silica porous body having macropores, the sol producing apparatus (1) including a mixing section (11) that prepares a mixed liquid (M) containing a silica precursor, a catalyst and a macropore forming agent, a first feeding section (12) that feeds the silica precursor to the mixing section (11), a second feeding section (13A) that feeds the catalyst and the macropore forming agent in admixture with each other, to the mixing section (11), a discharging pipe (14) that discharges the mixed liquid (M) from the mixing section (11), and a cooling section (15) that cools the mixed liquid (M) flowing through the discharging pipe (14), to 35? C. or less.

Provided are a macroporous titanium compound monolith and a production method thereof, the macroporous titanium compound monolith having a framework that is composed of a titanium compound other than titanium dioxide, having controlled macropores, and having electron conductivity, the titanium compound being oxygen-deficient titanium oxide, titanium oxynitride, or titanium nitride. Provided is a method including: placing a macroporous titanium dioxide monolith and a metal having titanium-reducing ability in a container, the macroporous titanium dioxide monolith having a co-continuous structure of a macropore and a framework that is composed of titanium dioxide; creating a vacuum atmosphere or an inert gas atmosphere within the container; and heating the monolith and the metal to cause gas-phase reduction that removes oxygen atom from the titanium dioxide composing the monolith by the metal acting as an oxygen getter, thereby obtaining a macroporous oxygen-deficient titanium oxide monolith having a co-continuous structure of the macropore and a framework that is composed of oxygen-deficient titanium oxide, the macroporous oxygen-deficient titanium oxide monolith having electron conductivity derived from the oxygen-deficient titanium oxide.
