  • 창의력 검사와 지능 검사와의 상관이 높게 나타남에 따라 창의력 검사가 지능 검사와 차별화된 능력을 측정하고 있는 지에 의문이 생겨났다. 본 연구에서는 유동성 지능과 결정성 지능을 측정하고, 이들과 창의력 검사와의 상관 관계를 조사함으로써 두 검사 사이에서 나타나는 상관관계의 원인을 탐색하고자 하였다. 이를 위해 창의력 검사로 널리 이용되는 Torrance Tests of Creative Thinking (TTCT)의 도형과 언어검사, 유동성지능을 측정하는데 대표적으로 이용되는 Raven's Advanced Progressive Matrices (RAPM), 유동성지능과 결정성지능 모두를 측정하는 Wechsler Adult Intelligence Scale (WAIS)을 과학고와 일반고 50명의 학생들을 대상으로 실시하였다. 실험결과 TTCT 도형과 언어 검사 모두 RAPM과의 상관은 유의미하지 않았으나 WAIS와의 상관은 유의미했다. WAIS 지능점수에 따라 학생들을 두 개의 그룹으로 구분했을 때 지능이 높은 그룹에서는 TTCT와 RAPM, WAIS의 상관결과가 모두 유의미하지 않았다. 지능이 낮은 그룹에서는 TTCT와 RAPM과의 상관은 유의미하지 않았으나 TTCT 도형 검사와 WAIS와의 상관은 유의미했다. TTCT와 WAIS 11개 소검사간의 상관 상관을 알아보았다. 분석결과 유동성지능을 잘 대표하는 소검사인 토막짜기, 모양맞추기, 숫자외우기는 TTCT 도형과 언어 검사 모두에서 유의미한 상관을 보이지 않았으며, 결정성지능을 잘 대표하는 소검사인 기본지식문제는 TTCT 도형과 언어 검사 모두에서 유의미한 상관을 보였다. WAIS 11개 소검사를 독립변인으로 하고 TTCT 전체 점수를 종속변인으로 하여 회귀분석을 한 결과 TTCT 도형과 언어 검사 모두 WAIS 소검사중의 기본지식문제가 TTCT 전체점수에 가장 높은 영향력을 미쳤다. 지능이 높은 그룹과 낮은 그룹에 대해 WAIS 11개 소검사와 TTCT 전체점수와의 상관을 구한 결과, 지능이 높은 그룹에서는 유의미한 상관을 의미는 소검사가 거의 없었던 것과는 달리, 지능이 낮은 그룹에서는 결정성지능을 대표하는 소 검사와 TTCT 도형검사 점수간의 상관이 유의미하게 나타났다. 이상의 결과를 통해 TTCT는 도형과 언어 검사 모두 유동성지능 보다는 결정성지능과 상관이 있음을 알 수 있는데, 이는 창의력 검사가 문제 해결 상황에 기존의 지식을 이용하는 능력을 측정하고 있기 때문으로 추정된다. 또한 지능이 낮은 그룹에서 높은 그룹에 비해 창의력 검사와 지능 검사 사이의 상관의 정도가 높았는데, 이는 일정 수준까지는 창의적 능력이 결정성 지능에 의해 제한을 받으나 일정 수준 이상의 결정성 지능을 갖게 되면 더 이상 결정성 지능이 창의적 능력을 제한하지 않기 때문인 것으로 해석된다.

  • The purpose of this study is to demonstrate the effects of authentic leadership on creativity, psychological safety, and the mediating effects of cooperative behavior in order to enhance the creativity of personnel as a means of innovation in enterprises. The hypothesis was established based on the theory and prior study of authentic leadership, creativity, psychological safety, cooperation behavior. The data collected from 353 employees of domestic enterprises were verified for reliability and validity through CFA, SPSS 25, and AMOS 25. Macro Process 3.0 was used for hypothesis testing. Verification of the hypothesis of the study model showed that authentic leadership had a significant positive effect on psychological safety, cooperation behavior and creativity, and that the mediating effect of psychological safety and cooperation behavior was also significant. The significance of this study can be found in the fact that the impact of authentic leadership has been verified based on motivation among the CMC (Componential Model of Creativity) and that it has suggested that creativity of an organization's personnel may be enhanced by changing organizational culture through leadership.

  • In semiconductor memory device manufacturing, the capability for high aspect ratio contact (HARC) etching determines the density of memory device. Given that there is no standardized definition of "high" in high aspect ratio, it is crucial to continuously monitor recent technology trends to address technological gaps. Not only semiconductor memory manufacturing companies such as Samsung Electronics, SK Hynix, and Micron but also semiconductor manufacturing equipment companies such as Lam Research, Applied Materials, Tokyo Electron, and SEMES release annual reports on HARC etching technology. Although there is a gap in technological focus between semiconductor mass production environments and various research institutes, the results from these institutes significantly contribute by demonstrating fundamental mechanisms with empirical evidence, often in collaboration with industry researchers. This paper reviews recent studies on HARC etching and the study of dielectric etching in various technologies.

  • In good laboratory practice (GLP), analytical method validation prior to toxicity testing is important in terms of concentration setting and sample preparation. The testing agency performed validation of the two requested test substances using high-performance liquid chromatography (HPLC), and as a result, the analysis satisfied the criteria for specificity, system suitability, linearity, intra-day reproducibility, homogeneity, stability, concentration analysis, and quality control. The method was established and validated. However, the content of standard substances in the test report of the requesting institution was found to be 1.34 and 1.17 times higher than the results of the testing institution, confirming that deriving results through validation of analysis methods suitable for GLP is important in terms of securing reliability and stability.

  • Regulation of $\beta$-galactosidase biosynthesis was studied with alkalophilic, thermophilic Bacillus sp. TA-11. Biosynthesis of the enzyme was effectively induced by lactose and some low level by isoprophyl-$\beta$-D-thiogalactopyranoside(IPTG). When 30mM glucose was added at the different intervals to the culture that had been in contact with lactose, the different levels of the enzyme synthesis were observed. So, this suggests that glucose interfered with the entry of the lactose into the cells.The glucose inhibitory effect was not relieved by adding cAMP to the culture.

  • Fluorescent anionic oligo surfactants were synthesized by the condensing products of long chain alkylvinylether-maleic anhydride cooligomers and resorcinol including dye structures. Their various surface activities and dispersing action were studied on the aqueous solution. These oligo surfactants exhibited a remarkable surface tension lowering property, lower foaming and a large dispersing action for the particles of ${\alpha}-copper$ phthalocyanine blue. Further it was ascertained that the binding of oligo surfactant onto the pigment surface caused the deviation towards lower wavelengths at the maximum fluorescent intensity as compared with aqueous oligo surfactant solutions, These surface active properties of the oligo surfactants may be attributed to rigid and hydrophobic structure of dye groups, besides surface-active groups of alkylether groups and carboxylic group of the anionic oligo surfactants.

  • Digital library technology is facing issues such as interoperability, content extension, and the need for a more efficient management environment. A system that is based on standardization and interoperability is required to resolve these issues. Open Digital Library is the system for the next generation that resolves the above problems. We have conducted some research on issues such as OAI and OAI-PMH, which are the basic knowledge behind the Open Digital Library technology and also investigated the Open Digital Library framework, cases of study and implementation of this technology. Finally, we have made some suggestions on the extendability of Open Digital Library technology using the standardized technologies.

  • As the surfactants that were used in micellar reaction, emulsion polymerization and phase-transfer reaction etc. have the problems, the cleavable surfactant that was converted to inactive compound after such as the reaction was synthesized to above 90% yield. And this surfactant and intermediates were separated through thin layer chromatography and column chromatatography and their molecular structures were confirmed from IR. $^{1}H$-NMR and elementary analysis spectra. And its surface-active properties and acid hydrolysis will be serialized in II.
