A non-toxic boron-containing material, carborane (C<SUB>2</SUB>B<SUB>10</SUB>H<SUB>12</SUB>) has been utilized to deposit amorphous hydrogenated carbon/boron (a-C/B:H) thin films in helium DC glow discharge. Helium plasma was produced by a filament discharge system connected with the carborane evaporation source at a target pressure of ~5 mTorr. The plasma discharge was performed by a pulsed mode at a duty cycle of 0.375 (3 s on/5 s off) or 0.23 (3 s on/10 s off). Deposited a-C/B:H thin films are characterized by variable angle spectroscopic ellipsometry, scanning electron microscope, Auger electron spectroscopy, and X-ray photoelectron spectroscopy. The a-C/B:H thin films show soft polymer-like characteristics with optical constants of n=1.65 and k=10<SUP>-3</SUP> at 632 nm and the B/C ratio inside the bulk is ~2 with ~60 % of boron contents. Evaporation characteristics of carborane powder under vacuum is also investigated.

Based on Theory of Planned Behavior (TPB), this research identified how the different factors of information security strategy orientations influence information security compliance intention of users. With a review of existing literature addressing information security problem this research introduces a new model, Information Security Policy Orientation Model ,with new concepts called Prevention Oriented Policy and Deterrent Oriented Policy.. The results of hypotheses test show that six out of eight hypotheses are supported. Specifically, POPM(the recognition toward Prevention Oriented Policy Means) has positive effect on PB(positive belief of information security to comply). The more POPM the employees recognized, the more PB(positive belief of information security to comply) they had. On the other hand, POPM negatively affect NB(negative belief of information security to comply). DOPM(the recognition of Deterrence oriented policy means) affects PB positively and NB negatively. Both POPM and DOPM have interaction effect on NB. Interestingly, POPM has stronger relationship with PB as well as NB than DOPM. Lastly, PB has positve efffect on IC(intention to comply information security policy) whereas NB has no significant effect on IC. In conclusion, this study suggests high investment on both POPM and DOPM to improve IC by increasing PB and decreasing NB. Accordingly, this study suggests to allocate resources more in POPM rather than in DOPM in case of resource shortage. This study will contribute to the extension of knowledge base with an interdisciplinary approach encompassing crime deterrence theory, situational crime prevention theory and psychology. The findings of this study suggest several practical implications. First, since this study identified the relationships among the cognition, beliefs, and intention to comply information security policy, it would provide information managers with the guideline to develop and implement the information security strategy and policies in organizations. Second, the practitioners could prioritize the investment on information security policy based on the findings of this study. Third, it is recommended to strengthen the strategic link between the business strategy and information security strategy to overcome the contradictions between productivity and information security policy. 본 논문은 비밀정보를 취급하는 특수한 조직의 사용자들을 대상으로 계획된 행동이론( Theory of Planned Behavior, TPB)에 근거하여 정보보안정책 지향성이 사용자들의 정보보안준수의도에 영향을 미치는지 밝히는 데 초점이 있다. 기존 문헌에 대한 조사를 토대로 본 연구는 전략적 정보보안준수모델이라는 새로운 이론적 모델을 제시하여 구조방정식분석방법을 이용하여 실증적 분석을 실시하였다. 이 연구의 목적은 1) 정보보안정책을 예방지향성과 억제지향성의 두 가지 개념으로 구분하였고, 2) 기존의 정보보안연구분야에 범죄학과 심리학의 이론을 접목하여 학제적 개념들을 융합하여 이 분야의 지식기반을 넓히는데 있다. 실증적 분석 결과, 정보보안 준수혜택에 대한 신념은 준수의도에 영향을 미치는 것으로 나타났지만 준수비용에 대한 신념은 준수의도에 그 영향이 통계적으로 유의하지 않은 것으로 나타났다. 준수 결과에 대한 신념에 미치는 영향을 보면, 예방지향적 정책에 대한 인지가 억제지향적 정책에 대한 인지보다 그 영향이 좀 높은 것으로 나타났으며 두 유형 모두 통계적으로 유의한 것으로 나타났다. 다만 준수비용에 대한 신념이 준수의도에 미치는 영향이 유의하지 않은 것으로 나타났다. 하지만 기술통계적인 관점에서 준수비용에 대한 신념이 준수의도와 부의 관계를 가지고 있으므로 준수비용에 대한 신념의 수준이 낮아지면 준수의도가 높아진다는 것을 보여주고 있다. 그리고 두 유형의 정책수단의 효과가 준수비용에 대한 신념과 모두 부의 관계를 보여주고 있으므로 결국 두 정책수단의 효과를 높이면 준수비용에 대한 신념의 약화를 거쳐 준수의도가 높아진다는 것을 보여주고 있다. 두 정책지향성의 인지가 신념에 상호작용하는 것으로 나타났으며, 예방지향성과 억제지향성에 대한 인지 수준을 동시에 높게 유지하는 것이 낮게 유지하는 것보다 준수비용의 신념을 더 저하시켜 준수의도를 높이는 것으로 나타났다.

The grouping analysis is a method guided by the Korea Radioactive Waste Agency for efficient analysis of radioactive waste for disposal. In this study, experiments to verify the adequacy of grouping analysis were conducted with radioactive soil, concrete, and dry active waste in similar environments. First, analysis results of the major radionuclide concentrations in individual waste samples were reviewed to evaluate whether wastes from similar environments correspond to a single waste stream. As a result, the soil and concrete waste were identified as a single waste stream because the distribution range of radionuclide concentrations was “within a factor of 10”, the range that meet the criterion of the U.S. Nuclear Regulatory Commission for a single waste stream. On the other hand, the dry active waste was judged to correspond to distinct waste streams. Second, after analyzing the composite samples prepared by grouping the individual samples, the population means of the values of “composite sample analysis results/individual sample analysis results” were estimated at a 95% confidence level. The results showed that all evaluation values for soil and concrete waste were within the set reference values (0.1e10) when five-package and ten-package grouping analyses were conducted, verifying the adequacy of the grouping analysis

An electric probe is a conductor inserted into the plasma, by which plasma density and electron temperature can be deduced from the collected current (Ⅰ) versus applied voltage (Ⅴ) to the probe. In RF plasma the Ⅰ-Ⅴ characteristics of electric probe is distorted due to the RF fluctuation of plasma potential, so that it is hard to measure the real plasma parameters, especially the electron temperature. To eliminate the RF fluctuation, several compensation methods are developed such as RF compensation probe, peak-to-peak method, asymmetric double probe. By comparing proposed methods, a suitable method is to be introduced in determining electron temperatures in RF plasma.
