DevOps는 개발과 운영을 배포 기간을 최소화함과 동시에 안정적인 운영을 목표로 하는 현재 가장 진보된 개발 문화이자 방법론이다. DevOps는 수많은 IT 기업에서 활용되고 있으며, 국방 분야도 마찬가지로 소프트웨어 전력 우위를 선점하기 위하여 DevOps 도입을 고려해왔다. 그러나 사이버 위협의 대응이 부족한 DevOps을 국방 소프트웨어에 적용하기가 쉽지 않다. 이에 미 국방부(Department of Defense, 이하 DoD)는 미래의 사이버 위협으로부터 국방 소프트웨어의 피해를 최소화하고자 DevOps 전 단계에 사이버 보안을 결합한 DevSecOps를 채택하여 개발 및 시범운영 중에 있다. 본 연구에서는 DevOps와 DevSecOps의 개념을 소개하고 국방 소프트웨어 분야의 적용 사례를 살펴본다. 그 중 DoD의 DevSecOps의구조, 구축 사례, 공급망 보안 방안을 분석하고 이를 바탕으로 우리 군의 DevSecOps 적용 가능성에 대해 논의하고자 한다.

The pathogenesis of cholestatic liver injury as well as the modulation of hepatic fibrogenesis is causally associated with involvement of reactive oxygen species (ROS) and free radical reactions. In this study, we investigated whether dried extracts of oriental medicine (LH) have antioxidant and antifibrotic effect under the biliary liver fibrosis (cirrhosis) c ondition. The female Sprague-Dawley rats were divided in six groups (Normal, N-LH, op-2, op-4, opLH-2, opLH-4) and were observed in 2 weeks or 4 weeks. For this purpose the rats were operated by bile duct ligation/scission (BDL/S), which induced to liver fibrosis and cirrhosis. After surgery, the prepared LH was administered p.o. 2 mι/day/rat in 2 weeks or 4 weeks for opLH groups. During the observation period, jaundices appeared in eyes, ears and tail of all BDL/S operated rats. And at the time of sacrifice, cholestasis was observed in proximal bile duct, especially the color of bile juice and urine in opLH-4 group showed more clear than op-2, op-4 and opLH-2 group. The value of clinical parameters and product of lipid peroxidation (MDA) in sera and the hydroxyproline (hyp) content in liver tissue were significantly increased in all liver fibrosis (cirrhosis) developed rats (p＜0.001~0.05). Among the clinical parameters of sera, value of BUN, ALP in opLH-4 group showed significantly lower than in op-4 group (p＜0.05, p＜0.001). The content of hyp in opLH-2, opLH-4 group (478.0 $\pm$ 134.3 $\mu\textrm{g}$/g 897.5 $\pm$ 118.2 $\mu\textrm{g}$/g) showed lower than in op-2, op-4 group (528.9 $\pm$ 220.7 $\mu\textrm{g}$/g, 1023.8 $\pm$ 277.1 $\mu\textrm{g}$/g) and then the value of MDA in opLH-4 was also significantly reduced to 59.4% of that in op-4 group (p＜0.001). The histological change (bile duct proliferation, fibrosis, collagen bundle) was similarly observed in op-2 group and in opLH-2 group, but the weak fibrosis and bile duct proliferation were observed in opLH-4 group compared with in op-4 group. Our data indicate that the 4 weeks treatment with LH extract suppressed lipid peroxidation and inhibited fibrotic (cirrhosis) process, and experimental cholestatic liver disease is associated with increased lipid peroxidation in BDL/S operated rats. Hence we concluded that the measurement of MDA and hyp can be useful monitor for the screening of antioxidant and antifibrotic effect in experimental liver fibrosis (cirrhosis), and LH has been shown to have hepatoprotective effect, antifibrotic effect and antioxidant effect.

Koreatech has adopted a long-term co-op program called IPP (Industry Professional Practice) to address problems in higher education of Korea since 2012, but it was anticipated to face many difficulties in implementing the program due to lack of relevant experiences in Korea. In this regard, a performance evaluation scheme was urgently required to judge the effectiveness of the Co-op program and improve the operational efficiency at the same time. This study aimed to develop comprehensive performance evaluation criteria for the co-op programs on the basis of Kirkpatrick's four-level performance evaluation model for training programs, and apply it to a real Co-op operation to test its feasibility. For this purpose, thorough review on the training program evaluation literature and in-depth analyses of overseas cases of co-op performance evaluation were conducted. Then, a set of Co-op performance evaluation criteria was developed and applied to the Koreatech's Co-op operation in 2013. Two Co-op student questionnaire surveys were administered before and after Co-op terms to measure students' reactions to the Co-op program (Level 1) and changes in participating students' attitudes and competencies (Level 2). In addition, employment rates of Co-op participating and non-participating students were compared (Level 4). The analysis findings showed that participating students were quite satisfied with their jobs and companies, and the Co-op program was effective to a certain degree at enhancing non-major competencies and attitudes to occupation of students. Together, the employment rate of Co-op participants, particularly in small- and medium-sized companies, grew significantly in comparison with that of non-participants. In the last part, several directions for improving the effectiveness of the Co-op programs were discussed.

Unlike pure art such as painting and sculpture, dressmaking , a field of special plastic art, is characterized by its physical and functional nature. Having an inseparable relation with form, it is a field of art expressiion the human innersense of beauty in correlation with other various fields of art. In this respect, I think it should be necessary for us to study the forms of art from the past in order to study the forms of art from the past in order to study the correlations and mutual influencies between forms of pure art and dressmaking and to understand modern dressmaking from the standpoint of art. In this context, this study is an attempt to analze how the form and characteristics of OP ART , which represents the trends of the 1960's is embodied in modern dresses. The results are as follows : Fist , the expression of OP ART in dresses have visual effects harmonizing with bodily movements and , also, expanded the range and dynamics of expression which resulted from the introduction of visual phenomena in a fresh new sense by not limiting itself to the suggestion of patterns of OP ART. Second, OP ART paintings expressed the mobility and rhythimicity of a body in a limited space in a two-dimensional plane way of expression . When a dress is worn, however, it expands such mobility and rhythmicity in a cubic , three-dimensional way, maximizing the effects of , and boldly expression, OP ART, it can also create a new silhuette and ability of formation by seeking an open expression of OP ART rather than an expression of OP ART it self , due to the infinite possibility and unpredictability by the dynamics of movements and the elements principle of designs. Third , by applying the patterns of OP ART to dresses, we can obtain special visual effects of design, cover up the body's weak points, and create a desired three -dimensional sense by highlighting the beauty of the body's curved lines. Although modern dresses and OP ART are different genres of art, both have something in common in their pusuits. Since there is a infinite possibility in OP ART, there should be continuous attempts to combine dresses and art satisfying the sense of the times, which will lead dressmaking to a higher-dimensional dressmaking plastic art.

The chronic cholestasis induce to biliary liver fibrosis (cirrhosis) and the increased products of ROS(reactive oxygen species) cause to the liver damage. In this study ; the antioxidant and antifibrotic effect of dried extracts of oriental medicine (DW) was investigated under the liver fibrotic (cirrhotic) condition. The female Sprague-Dawley rats were divided in 5 groups (Normal, Op-2, Op-4, OpDW-2, OpDW-4). Except for normal group, the rats were induced to biliary liver fibrosis (cirrhosis) by the operation of bile duct ligation/scission (BDU/S) and were observed in 2 weeks or 4 weeks. And the prepared DW was treated p.o.2 ml/day/rats in 2 weeks or 4 weeks for OpDW groups. At the time of sacrifice, the liver, kidney, spleen were weighed and the ratio of organ weight/body weight was calculated. The MDA, the hyp and biochemical parameters (GOT GTP, ALP, t-bili) were measured in sera and liver tissue of rats. The biochemical change was observed on liver tissue. In the result, the hepatomegaly and spleenomegaly appeared in all BDL/S operated rats, and significantly lower liver weight was observed in OpDW-4 group compared with in Op-4 group (p<0.05). The level of clinical parameters in sera of all liver fibrosis (cirrhosis) developed rats was higher than in normal group. Especial1y, the value of GOT in OpDW-2 group and ALP in OpDW-4 group showed significantly lower than in Op-2 group and Op-4 group (p<0.01, p<0.005). The content of hyp in all operation groups was significantly higher than in normal group (p<0.05∼<0.005), and showed significantly lower value in the OpDW-4 group than in Op-4 group (p<0.05). The product of lipid peroxidationUDA) increased significantly under the fibrotic(cirrhotic) condition (p<0.05∼ <0.005), and the MDA value in OpDW-4 group decreased significantly in Op-4 group (p<0.005). The histological change (bile duct proliferation, fibrosis, collagen bundle) was similarly observed in Op-2 group and in OpDW-2 group, but the weak fibrosis and bile duct proliferation were observed in OpDW-4 group compared with in Op-4 group. In conclusion, lipid peroxidation and severe liver damage were activated by bile duct obstruction, and the measurement of MDA and hap can be useful monitor for the screening of antioxidant and antifibrotic effect in experimental liver fibrosis (cirrhosis). The 4 weeks treatment with DW extracts suppressed lipid peroxidation and inhibited fibrotic (cirrhotic) process in BDL/S operated rats.

In this study, we have investigated photo-induced changes of optical energy gap( $E_{OP)}$ and photoluminescence (PL) in amorphous ($\alpha$-) S $e_{100-x}$G $e_{x}$ (x=5, 25 and 33) thin films prepared by conventional thermal evaporation method. In the $\alpha$-S $e_{100-x}$G $e_{x}$ thin film, the $E_{OP}$ is obtained by a linear extrapolation of the ($\alpha$hν)$^{\frac{1}{2}}$ versus hν plot to the energy axis using the optical absorption coefficient ($\alpha$) calculated from the extinction coefficient k measured in the wavelength range of 290~900nm. Although the values of $\Delta$ $E_{OP}$ are very different, all films exhibit photo-induced photo-darkening (PD) effect that is a red shift of $E_{OP}$ . In particular, $\Delta$ $E_{OP}$ in $\alpha$-S $e_{75}$ G $e_{25}$ thin film exhibits the largest value (i, e., $\Delta$ $E^{OP}$ ~40meV for $\alpha$-S $e_{95}$ G $e_{5}$ , $\Delta$ $E_{OP}$ ~200meV for $\alpha$-S $e_{75}$ G $e_{25}$ , $\Delta$ $E_{OP}$ ~130meV for $\alpha$-S $e_{67}$ G $e_{33}$ ). PL spectra in $\alpha$-SeGe by hν$_{HeCd}$ have no-Stokes shift (SS) and show a tendency dependent on both composition and illumination time. We explain the energy-induced phenomena such as the PD and thermal bleaching, the native charged-defect generation and the no-SS PL, etc..the PD and thermal bleaching, the native charged-defect generation and the no-SS PL, etc..tc..
