In this paper, we present an efficient way of implementing OpenGL ES 1.1 standard for the environments with hardware-supported OpenGL API, such as desktop PCs. Although OpenGL ES was started from the existing OpenGL features, it becomes a new three-dimensional graphics library customized for embedded systems through introducing fixed-point arithmetic operations, buffer management with fixed-point data type supports, completely new texture mapping functionalities and others. Currently, it is the official three dimensional graphics library for Google Android, Apple iPhone, PlayStation3, etc. In this paper, we achieved improvements on the arithmetic operations for the fixed-point number representation, which is the most characteristic data type for OpenGL ES. For the conversion of fixed-point data types to the floating-point number representations for the underlying OpenGL, we show the way of efficient conversion processes even with satisfying OpenGL ES standard requirements. We also introduced a simple memory management scheme to mange the converted data for the buffer containing fixed-point numbers. In the case of texture processing, the requirements in both standards are quite different and thus we used completely new software-implementations. Our final implementation result of OpenGL ES library provides all of over than 200 functions in OpenGL ES 1.1 standard and completely passed its conformance test, to show its compliance with the standard. From the efficiency viewpoint, we measured its execution times for several OpenGL ES-specific application programs and achieved at most 33.147 times improvements, to become the fastest one among the OpenGL ES implementations in the same category.

The purpose of this study is to analyze the characteristics of teacher librarians' efficacy and to propose some ways to enhance their efficacy. To do this, questionnaires on 30 teacher librarians who participated in the level 1 certification program of K university in 2018 were conducted. The results showed that their average efficacy was 3.38, the efficacy of teaching method was 3.60, the collective efficacy was 3.38, and the personal efficacy was 3.18. They had high personal efficacy on classroom management, the willingness to lead poor students and the possibility of problem student guidance, and collective efficacy on conflict management with fellow teachers and parents. On the other hand, personal efficacy in problem analysis and guidance for problem students, difficult contents and course instruction were low. Also, the collective efficacy of the conflict between the manager and the education office was low. They have a strong willingness to improve teaching methods for students and showed high efficacy about student synchronization and preparation for teaching. However, they were aware of the lack of learning skills and the lack of various teaching methods. The variables influencing their efficacy were graduation, education level, school size, and degree. Especially, the higher the education level, the more confident and enthusiastic about teaching problemmatic students and disadvantaged students. In addition, teacher librarians with high academic standards showed high confidence in conflict resolution with peers and parents and teaching methods. The improvement direction to enhance their efficacy in this study are increasing the ratio of teacher education in the field of education, reforming teacher librarians training before appointment, establishing supervision organizations for school libraries and improving their professionalism by going to graduate school.

While the government policy to fully adopt BIM in the construction sector is being implemented, the construction and utilization of landscape BIM models are facing challenges due to problems such as limitations in BIM authoring tools, difficulties in modeling natural materials, and a shortage in BIM content including libraries. In particular, plants, fundamental design elements in the field of landscape architecture, must be included in BIM models, yet they are often omitted during the modeling process, or necessary information is not included, which further compromises the quality of the BIM data. This study aimed to contribute to the construction and utilization of landscape BIM models by developing a plant library that complies with BIM standards and is applicable to the landscape industry. The plant library of trees and shrubs was developed in Revit by modeling 3D shapes and collecting attribute items. The geometric information is simplified to express the unique characteristics of each plant species at LOD200, LOD300, and LOD350 levels. The attribute information includes properties on plant species identification, such as species name, specifications, and quantity estimation, as well as ecological attributes and environmental performance information, totaling 24 items. The names of the files were given so that the hierarchy of an object in the landscape field could be revealed and the object name could classify the plant itself. Its usability was examined by building a landscape BIM model of an apartment complex. The result showed that the plant library facilitated the construction process of the landscape BIM model. It was also confirmed that the library was properly operated in the basic utilization of the BIM model, such as 2D documentation, quantity takeoff, and design review. However, the library lacked ground cover, and had limitations in those variables such as the environmental performance of plants because various databases for some materials have not yet been established. Further efforts are needed to develop BIM modeling tools, techniques, and various databases for natural materials. Moreover, entities and systems responsible for creating, managing, distributing, and disseminating BIM libraries must be established.

This paper describes an efficient implementation of ARIA crypto algorithm which is a KS (Korea Standards) block cipher algorithm. The ARIA crypto-processor supports three master key lengths of 128/192/256-bit specified in the standard. To reduce hardware complexity, a hardware sharing is employed, which shares round function in encryption/decryption module with key initialization module. It reduces about 20% of gate counts when compared with straightforward implementation. The ARIA crypto-processor is verified by FPGA implementation, and synthesized with a 0.13-${\mu}m$ CMOS cell library. It has 33,218 gates and the estimated throughput is about 640 Mbps at 100 MHz.

The volatile components in 'Fuji' apple were effectively determined by a headspace solid-phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS). A total of 48 volatile components were identified and tentatively characterized based on National Institute of Standards and Technology (NIST) MS spectra library and the Kovats GC retention index I (RI). The harvested Fuji apples were divided into two groups: 1-methylcyclopropene (1-MCP) treated and non-treated (control) samples for finding important indicators between two groups. The major volatile components of both apples were 2-methylbutyl acetate, hexyl acetate, butyl 2-methylbutanoate, hexyl butanoate, hexyl 2-methylbutanoate, hexyl hexanoate and farnesene. No significant differences of these major compounds between 1-MCP treated and non-treated apples were observed during 1 month storage. Interestingly, the amount of off-flavors, including 1-butanol and butyl butanoate, in 1-MCP treated apples decreased over 5 months, and then increased after 7 months. However, non-treated apples did not show significant changes for off-flavors during 7 month storage (p<0.05). The non-treated apples also contained the higher levels of two off-flavors than 1-MCP treated apples. These two compounds, 1-butanol and butyl butanoate, can be used as quality indicators for the quality evaluation of Fuji apple.
