  • 최근 기업에서는 사무생산성을 향상시키기 위하여 조직의 특성에 맞는 사무자동화 기기를 도입하여 운영하고 있다. 조직에 따라 OA추진 방식이 다양하므로 OA 추진현황을 분석하여 성공적으로 OA를 추진할 수 있는 방안을 제시할 수 있다면 의미가 있다고 하겠다. 본 연구에서는 현재 우리나라의 OA현황을 조사분석하여 기업이 OA를 추진하는데 가장 적합한 추진방향을 제시하는 것을 목적으로 한다. 따라서 개략적인 OA추진운영 현황을 파악한 후 추진특성별 운영방식과 추진운영별 도입성과를 확인하여 OA도입성과를 극대화하는 추진방향을 제시하고자 한다. 연구조사를 위해 OA 추진 업체와 OA 관련 종사자를 대상으로 우편 설문조사를 실시하여 자료를 수집하였다. 연구결과는 대기업의 경우 OA가 일정수준에까지 도달하였으며, 대부분 장단기계획을 수립한 후에 OA를 추진하고 있으나 투자비용 제한, 개발인력 부족, OA기기에 대한 저항감과 같은 문제점을 안고 있는 실정이므로 이러한 문제점을 해결할 수 있는 방안을 마련하여 OA를 활성화하는 것이 바람직하다. OA실무자는 단순반복업무를 담당하고 있어 업무처리와 관리방식 개선과 같은 근본적인 업무를 거의 하지 못하고 있다. OA도입성과를 극대화하여 성공적으로 OA를 추진운영하기 위해서는 장기계획을 수립하여 추진하고 실무자의 의견을 반영하여 중대형 컴퓨터와 연계활용해야 하는 것으로 나타났다.

  • This study aims to review the possibility of OA to international journal articles cited by researchers of the library and information science field in Korea. For this, the international journal articless cited to the articles (1,543) of the Korean Society for Information Management were collected, and the investigation was carried out regarding the OA policy of the international journals and the status of journals that can be open to the public through the OA according to the OA policy. In addition, this study analyzed the actual accessibility by utilizing the OA finders (Google Scholar, Unpaywall, OA Button). The analysis result indicated that the majority of the international journals were using the green OA policy. Also, 1,476 journal articles which is 95.4% of the total international journal articles were allowed to be accessed officially with the OA. The results of reviewing the actual accessibility rate of the journal articles open to the public through the use of the OA finders indicated that accessibility was up to 68% when using Google Scholar, and the maximum accessibility rate was 72% when mixing the OA finders. Among the OA finders, Google Scholar had the greatest OA accessibility rate, but it was desirable to mix the OA finders in order to expand the OA accessibility rate to the maximum level.

  • This study was focused on the synthesis of methoxy polyethylene glycol-oleanolic acid ester (mPEG-OA derivative) and investigation of its water solubility and anti-melanogenic effects. mPEG-OA derivative was identified by 1H and 13C NMR and FT-IR spectroscopic measurements. The water solubilities of mPEG-OA derivative and OA were found to be 13 and 0.013 mg/mL and that of mPEG-OA was found to be 1000-fold higher than that of OA. The effects of mPEG-OA derivative and OA on cell viability were measured using B16F10 melanoma cells. The viability of cells treated with mPEG-OA derivative (250 μM) increased 4-fold compared to that of cells treated with OA (62.5 μM). At mPEG-OA derivative and OA concentrations where the cell viability was unaffected, the inhibitory effect of mPEG-OA derivative and OA on the melanogenesis in B16F10 melanoma cells were 36 and 35% at 50 and 10 μM, respectively. The expression level of microphthalmia-associated transcription (MITF) was also reduced in B16F10 melanoma cells treated with mPEG-OA and OA. Overall, mPEG-OA derivative showed excellent water solubility and inhibitory effects of the melanogenesis, which could be used as a potential formulation for use in whitening functional cosmetic material.

  • OA journal publishing has steadily increased its relative share of all scholarly journal articles by about 20%-30%. The 'Gold' OA, often preferred by readers, refers to journal articles which are more widely available through the journal's web site immediately. This study analyzed funder and university's policy for paying APCs in implementing a Gold OA. In recent years there have been a number of attempts in the UK and Europe to stimulate more systematic arrangements for paying APCs, leading funders have clearly established arrangements in place. Also OA fund made by major universities in North America provides publisher with APCs. On the other hand, it is still in early stages in paying with gold OA requirements from Korean funders and universities. The funders have a 'Green' OA policy, such as upload the article accepted version to their online platform. Although it varies by field, many Korean authors are publishing in international journals. Their articles' impacts would rise when they are published as gold OA. Therefore, funders and universities need to pay attention to gold OA publishing and set up subsidies for APCs which are required by OA or hybrid journal publishers.

  • This study was carried out to confirm the chromosome constitution and homoeologous recombination of progenies derived from various cross combination using tetraploid OA interspecific hybrid originated from mitotic chromosome doubling. Based on the chromosome analysis of progenies crossed reciprocally, there were only triploid progenies when crossed with diploid Asiatics as male or female parent. While only tetraploid progenies were produced when crossed tetraploid Asiatics or tetraploid OA hybrid with tetraploid OA hybrid, respectively. However, two types of progenies, that is, diploid and triploid plants, were produced from cross combinations between diploid Oriental hybrid and tetraploid OA hybrid. From the GISH analysis of OA hybrid, it was confirmed that diploid $F_1$ OA hybrid was consisted of 24 chromosomes (12 Oriental and 12 Asiatics) showing authentic OA hybrid. On the other hand, it was notified that triploid plants (3x=36) were consisted of 24 Asiatics lily chromosomes and 12 Oriental lily chromosomes by analysis of backcross progenies derived from either $A{\times}OA$ or $OA{\times}A$ crosses. In cross between tetraploid OA and OA, all the progenies were tetraploid with equal number of chromosomes without any homoeologous recombination, i.e. each 24 chromosomes of Oriental and Asiatics. In 2x-4x ($O{\times}OA$) cross combination, some progenies had 2x=24 chromosomes originated from only Oriental hybrid, and other progenies had 3x=36 chromosomes derived from 24 chromosomes of Oriental hybrid and 12 chromosomes of Asiatic hybrid. Only tetraploid Asiatics chromosomes without any Oriental one were produced in all the progenies from 4x-4x ($AA{\times}OA$) cross combination.

  • This study was carried out to establish breeding system for interspecific hybridization of Lilium using spontaneous meiotic polyploidization of $F_1$ OA hybrid and its progenies. Pollen viability and germination of $F_1$ OA interspecific hybrid showed variation by collection time, indicating that pollen grain in June, which was natural blooming season, had better viability and germination ability than in October. 2n-gametes from spontaneous meiotic polyploidization of OA hybrid were crossed with either diploid Asiatic or Oriental hybrid, and subsequent progenies crossed with Asiatic hybrid as female and OA hybrid as male showed the highest efficiency, where 2x-2x A$\times$OA produced 0.64 plants per cross combination, while 2x-2x, O$\times$OA and 2x-2x, OA$\times$A crosses produced 0.42 and 0.4 plant per ovary, and especially no progeny was obtained in 2x-2x, OA$\times$O cross combination. For the subsequent progeny production, a cross between diploid Asiatic hybrid as female and diploid OA hybrid as male was the best ploidy combination. Ploidy level of subsequent progeny derived from backcross with 2n-gametes of OA hybrid revealed that triploids from 2x-2x OA$\times$A, tetraploids from both 4x-2x, AA$\times$OA and OO$\times$OA, diploid from 2x-2x, O$\times$OA, and diploids or triploids from 2x-2x, A$\times$OA crosses were produced respectively.

  • The antioxidative activities of capsaicin (Cap, 0.02 and 0.04%) on the lipid peroxidation of tissues in male Sprague Dawley rats fed diets with or without orotic acid (1.0%, w/w) were studied in vivo system by measuring thiobarbituric acid reactive substances (TBARS) concentrations. Body weight gain, food intakes, food efficiency ratio and the relative tissues weights of brain, kidney, spleen, heart, and testis were not significantly different among dietary groups. Relative weights of liver were higher in the OA group than that in the other groups. TBARS concentrations in liver were significantly higher in the OA or 0.04% Cap groups than in the normal group, while this raise was not observed 0.02% Cap group. A significant increase in TBARS concentrations was found in the liver of the OA +0.04% Cap group compared with the OA or the 0.04% Cap groups. Nonheme iron concentrations were significantly higher in the liver of the OA, 0.04% Cap, OA+0.02% Cap, OA+0.04% Cap groups than that in the normal group. TBARS concentrations in kidney were lower in the 0.02% or 0.04% Cap groups than that in the normal group, but this concentrations were higher in either the OA, OA+0.02% Cap or OA+0.04% Cap groups than that in the normal group. Meanwhile, TBARS concentrations of brain, spleen, heart and testis were not significantly different among groups. The present study suggested that the lipid peroxidation was increased in the rats liver fed diet with erotic acid, and the simultaneous supplementation of capsaicin further enhanced.

  • Changes in erotic acid (OA) contents of raw milk and during cultivation and storage at refrigerated temperature were determined. OA contents of raw and 10% reconstituted milk held at $121^{\circ}C$ for up to 15 min decreased by 17.6 and 22.4%, and those fermented at 40 and $37^{\circ}C$ for 72 hr with Lactobacillus helveticus 166 and Lactobacillus casei 955 decreased 37.8-43.2 and 41.8-76%, whereas when fermented at $40^{\circ}C$ for 72 hr with Streptococcus thermophilus ST-37, did not decrease significantly compared with fermentation by other lactobacilli. OA content did not change during storage at refrigeration temperature. OA reduction by Lactobacillus sp. was dramatically increased at the initiation of stationary phase during fermentation. OA reduction varied among different lactobacilli. These results show decrease in cultivation time, rapid cooling of yogurt, and proper selection of Lactobacillus sp. prevent OA content reduction.

  • This study empirically analyzed the proportion and method of Open Access (OA) in Korea, China, Japan, the United States, United Kingdom based on the Web of Science (WoS) papers. In addition, through the verification of the moderating effect, it was verified whether there is a difference in the effect of the amount of citation depending on the maturity of OA according to the countries or academic fields. As a result of the analysis, the proportion of OA was the highest in the UK at 62.7%, and the lowest in China at 38.0%. Second, the UK and US had a high proportion of indicators through self-archiving and APC-based Gold Hybrid, while only the Gold indicators were found to be prominent in China and Korea. Third, in the UK, US and Japan, the higher the proportion of OA, the greater the effect of inducing the citations. However, Korea (B=-0.00003, p<0.01) and China (B=-0.00001, p<0.01) showed the opposite direction. In addition, in most academic fields, the OA proportion had an effect of inducing citation, but a negative effect was found in the engineering field (B=-0.00002, p<0.01).
