이상기,김영덕,최용락 대전대학교 산업기술연구소 1998 산업기술연구소 論文集 Vol.9 No.2

Until recently, the integration of cryptographic functionality into application program has required that developers tightly couple the application to the cryptographic module. This approach forces each new combination of application and cryptography to be treated as a distinct development effort, and does not provide the modularity and maintainability. An approach that can provide flexibility and cost saving is the use of a standardized CAPI(Cryptographic Application Prigram Interface) suite. This Paper analyze the CAPI for the development of various types of security application programs in distributed environment. The analysis of CAPI are considered with the respect of 7 criteria items such as algorithm independence, application independence, cryptomodule independence, the degree of cryptographic awareness, modular design and auxiliary services, safe programming and security perimeter. In this paper, we suggested the basis of utilization to be selected for develope the cryptographic modules in distributed applications.

소나무와 리기다소나무의 수간류 및 수관통과우의 화학적 성질

이상덕,이명종,주영특 강원대학교 삼림과학연구소 2001 Journal of Forest Science Vol.17 No.-

수간류, 수관통과우의 화학적 성질변화에 미치는 수종간 차이의 영향을 비교하기 위하여 강원대학교 구내의 소나무림과 리기다소나무림을 대상으로 하여 조사, 분석하였다. 임의우의 평균 pH는 6.2였으며, 소나무의 수관통과우>소나무의 수간류>리기다소나무의 수관통과우>리기다소나무의 수간류 순의 평균 pH값을 보였다. 또한 6월을 제외한 대부분의 조사기간 동안 임의우의 pH가 수간류와 수관통과우의 pH보다 높게 나타났다. 다른 원소에 비하여 양이온은 Ca2+과 K+이, 음이온은 NO3-과 SO42-이 타원소에 비하여 높게 나타났으며, 특히 11월에 K+, Mg2+, Na+이 증가하였다. 한편, 소나무와 리기다소나무의 수간류와 수관통과우에 있어서의 용존원소 농도는 임외우 보다 높게 나타났다. This research was carried out to investigate the effects of the different tree species (Pinus densiflora and Pinus rigida) about the chemical properties of stemflow and throughfall at Chuncheon city in Kangwon province. The water quality of the rainfall, stemflow and throughfall in each forest stands were analyzed chemically. The pH average of precipitation was pH 6.2 and pH averages were throughfall of P. densiflora> throughfall of P. rigida> stemflow of P. rigida during the study period. During the all period, the pH of precipitation was higher than the pH of stemflow and throughfall except on June. The concentration of cation(Ca2+ and K+) and anion(NO3- and SO42-) were higher than others. Especially on November, the concentration of K+, Mg2+, Na+ were increased. The concentration of dissolved elements of stemflow and throughfall (Pinus densiflora and Pinus rigida) were higher than precipitation. Key words : precipitation, stemflow, throughful, Pinus densiflora, Pinus rigida,

The correlations of ocular refractive error and higher-order aberrations were exam- ined. The measurement of refractive error and higher-order aberration used KR-9000PW. the wavefront aberrometer with Hartmann-Shack method, and the 44 subjects (88 eyes) with S.E. value of 0.00D to -9.04D were considered for analysis. As the result of Pearson correlation analysis for S.E. and higher-order aberration RMS, Coma aberration showed a significant correlation (r=0.251, p<0.05) with S.E., but Trefoil aberration, Tetrafoil aberration, Spherical aberration, 2nd Astigmatism and such showed no significant correlation with S.E. Also, the 3rd aberration including Trefoil aberration and Coma aberration showed a significant correlation with S.E. (r=0.244, p<0.05), but 4ch aberration and total higher-order aberration showed no significant correlation with S.E. The cylinder refractive error had no significant correlation with all higher order aberrations. In comparison to higher-order aberration RMS value, the group with S.E. below -1.00D the high myopia group over -6.00D, only the total higher-order aberration and 3rd aberration RMS showed a significant difference (p<0.05), and all other aberrations showed no significant difference in the RVS value between the two groups. Only Coma aberration and Zernike Polynomials 3rd order aberration RMS showed a statistically significantly low correlation with S.E., and cylinder refractive error (C) showed no significant correlation with all higher-order aberrations. In comparison to the group with S.E. below -1.00D and the group over -6.00D, only the total higher-order aber-ration and 3rd aberration RMS showed a significant difference between the two groups.

Based on an approach proposed to calculate the direct reaction (DR) and fusion probabilities for heavy ion collisions, simultaneous x -analy- ses are performed of data of the elastic scattering, DR and fusion cross sections for the 6He+209B1 system at near-Coulomb-barrier energies, determining parameters of the polarization potential, consisting of DR and fusion parts. We show that the data are well reproduced by the potential that satisfies the dispersion relation. A Discussion is also given of nature of the threshold anomaly of the extracted potential.

안경사 국가시험 합격률 관련 변인에 관한 연구

In order to find out whether those variables such as grade, admission type, age, origin, and sex are related to the success in the national optician licence examina-tion, Chi-Square verification was conducted. As a result of the verification, there was no statistically significant impact of age, origin or sex on the success in National Optician Examination (p>0.05). However, grade of the achieved at college and the admission type on the success in National Optician Examination, there was a statistically significant impact (p<0.01). Concerning the age, because the older group reported better grades and the younger group reported the opposite, I expected the grade and success in the exam to have a quite significant relationship. However, there was no meaningful difference. For the admission type, the students from general admission reported the high-est success rate, 86.1%, while the students from Farming and Fishing Communities admission reported the lowest rate of 50.0%, which was far lower than the average success rate of 80.6%. The grade at college was found out to be significantly related to the success in the exam. Among the students with a grade point average of over 3.5(116 stu-dents), only four failed the exam, while almost everyone, as high as 96.6% of the total, passed the exam. However, the students with a grade point average of lower than 3.0(93 students) revealed a 52.7% success rate, meaning that only half of them could pass the exam. This was a far lower rate than the average success rate of 80.6%.

The study measured ocular higher-order aberrations in the range of pupil diameter 6mm and 4mm with Hartmann-Shack wavefront aberrometer. In RMS of ocular high-order aberrations in the range of pupil diameter 6mm, it was measured that Trefoil aberration was 0.183 m, Coma aberration 0.170um, Tetrafoil aberration 0.074jum, 2nd Astigmatism aberration 0.0654m and Spherical aberration 0.1134m. It was measured that 3rd and 4th aberration were 0.2594m, 0.164_m respectively and total HOA was 0.332 m. Total RMS of ocular higher-order aberrations in 6mm was 3.39 times as much as that of 4mm. Aberration between 4mm and 6mm occupied 70% of the total 6mm range. Especially, Spherical aberration had the largest difference as 4.35 times and the aberra-tion within that range occupied 77%. Therefore, the study can see that the aberration is influenced most as the pupil becomes bigger and bigger. In correlation analysis among each aberration in the range of 6mm, Coma aberration had a significant correlation with all aberrations such as Trefoil, Tetrafoil, 2nd Astigmatism and Spherical. In addition, Spherical and Trefoil, Spherical and 2nd Astigmatism, Trefoil and Tetrafoil, Tetrafoil and 2nd Astigmatism had significant corre- lations respectively. The study found that 3rd aberration and 4th aberration also had a significant correlation.

WAP 2.0 기반의 무선인터넷 일정관리 시스템의 구현

이효영,이덕영,이상민 강원대학교 정보통신연구소 2005 정보통신논문지 Vol.9 No.-

In recent years, telecommunication technologies have been developed rapidly. According to the change of life style, the demand on the wireless internet is increased. The Wireless Application Protocol (WAP) 2.0 is an open, global specification that empowers mobile users with wireless devices(such as mobile phones) to easily access and interact with information and services on the Internet. In this study, a wired/wireless internet schedule management system is implemented to arrange the schedule effectively. This system supports access through different technologies, notably through a web interface and through a WAP 2.0 interface. Both systems share the database in the server computer. The implemented wireless system has graphic user interface and security as a benefit of WAP 2.0.
