In this paper, we propose a more effective unique identifier allocation method for macro expansion in a single-process multicore parallel computing environment that does not require locks. Our key idea for such an allocation method is to remove sequential dependencies using the remainder operation. We confirmed that our lock-free method is suitable for improving the performance of parallel macro expansion through the following benchmark: we patched an existing library, which is based on a sequential unique identifier allocation, with our proposed method, and compared the performances of the same program but using two different versions of the library, before and after the patch.

The method of single-cell RNA sequencing has been rapidly developed, and numerous experiments have been conducted over the past decade. Their results allow us to recognize various subpopulations and rare cell states in tissues, tumors, and immune systems that are previously unidentified, and guide us to understand fundamental biological processes that determine cell identity based on single-cell gene expression profiles. However, it is still challenging to understand the principle of comprehensive gene regulation that determines the cell fate only with transcriptome, a consequential output of the gene expression program. To elucidate the mechanisms related to the origin and maintenance of comprehensive single-cell transcriptome, we require a corresponding single-cell epigenome, which is a differentiated information of each cell with an identical genome. This review deals with the current development of single-cell epigenomic library construction methods, including multi-omics tools with crucial factors and additional requirements in the future focusing on DNA methylation, chromatin accessibility, and histone post-translational modifications. The study of cellular differentiation and the disease occurrence at a single-cell level has taken the first step with single-cell transcriptome and is now taking the next step with single-cell epigenome.

Monolithic three-dimensional (M3D) logics such as M3D-NAND, M3D-NOR, M3D-buffer, M3D 2×1 multiplexer, and M3D D flip-flop, consisting of modularized M3D inverters (M3D-INVs), have been proposed. In the previous M3D logic, each M3D logic had to be designed separately for a standard cell library. The proposed M3D logic is designed by placing modularized M3D-INVs and connecting interconnects such as metal lines or monolithic inter-tier-vias between M3D-INVs. The electrical characteristics of the previous and proposed M3D logics were simulated using the technology computer-aided design and Simulation Program with Integrated Circuit Emphasis with the extracted parameters of the previously developed LETI-UTSOI MOSFET model for n- and p-type MOSFETs and the extracted external capacitances. The area, propagation delay, falling/rising times, and dynamic power consumption of the proposed M3D logic are lower than those of previous versions. Despite the larger space and lower performance of the proposed M3D logic in comparison to the previous versions, it can be easily designed with a single modularized M3D-INV and without having to design all layouts of the logic gates separately.

In an attempt to study the current status and ways to revitalize cultural programs in small libraries, this study surveyed 142 small libraries based in the Seoul. Two most important functions of both public and private small libraries were found to be the loan/return of materials and cultural programs; over 50% of small libraries are operating cultural programs. It was also found that institutions that did not operate the cultural programs were aware of the necessity. Both public and private small libraries were operating one to three cultural programs, and their types varied from cultural refinement to reading-related programs. There was a higher rate of answers stating that the person in charge of operating cultural programs for public small libraries were administrative personnels, while the chief librarian was the person in charge for private small libraries. The hardships both types of libraries encountered were found to be budget-related and on securing manpower.

This study investigates 185 public librarians' perceptions, satisfactions score and loyalty for CIP program operated by the National Library of Korea. The 172 (93.0%) librarians have perceived about the CIP, and 98(57.0%) librarians make use of the CIP at their works. They were relatively high perceptions on the service quality (3.50), satisfaction (3.71), and loyalty (3.72) for the CIP on the Likert 5-point scale. This study also tested the quality of service, satisfaction and loyalty using Structured Equation Model(SEM) models. Research findings show that CIP data quality had a statistically meaningful positive impact on user satisfaction and user satisfaction had a meaningful positive impact on loyalty.
