  • 운영 연속성관리 문제는 지원센터(back-up center)나 대안 사이트(alternate site) 등에 의해서 해결될 수 있는 단순한 이슈가 아니기 때문에, 운영 연속성 관리 측면에서 법률, 기준 등을 포함하는 전략적 이슈는 새로운 접근 방법을 요구하고 있다. 이와 아울러 기업 거버넌스의 한 부분으로서 OCM(Operational Continuity Management) 거버넌스를 포함하는 새로운 프레임 워크를 개발할 필요가 있다. 기업 거버넌스 전문가들은 OCM이 기업 운영 제어에 포함될 수 있으며 조직의 OCM을 위한 전력 수립에 있어서 중요한 역할을 담당할 것으로 주장하고 있다. 본 연구에서는 이러한 OCM 거버넌스가 기업 거버넌스 측면에서 효율적으로 기업의 위험을 조절하는 방법에 대해서 크게 두가지 사항을 제안하고자 한다. 첫째, 최상위 기업관리에 있어 기업 거버넌스 측면에서 운영 연속성을 위한 전략을 개발하고자 한다. 둘째, 기업에 있어서 운영 연속성 전략을 어떻게 수립하고 관리해나가는 지에 대해서 제안하고자 한다.

  • According to the MARPOL 73/78 of Convention, all ships should have oil filtering equipment and 15 ppm bilge which satisfy Requirements of MARPOL 73/78. This study is concerned with designing and manufacturing a prototype Oil content Meter(OCM) used in machinery area of ship. The prototype OCM is composed of two parts which are oil content sensing module and data processing unit. The oil content sensing module consists of infra-red light source, photo-diode light receivers, and a glass tube for bilge water sample. The data processing unit has a micro-processor as hard core and peripheral devices. The experimental results of prototype OCM and analysis of collected data reveal linear property between transmitted light and scattered light as long as the bilge water has low level content of oil. And this linear property leads to a oil content detecting method which is programmed and loaded into the data processing unit. The performance of the prototype OCM is compared with that of the commercial OCM in the market.

  • The purpose of this study was to identify the relative influence of OCM and BSM's family functioning dimensions and develop a new family system model related to adolescent adjustment. The 443 subjects were selected randomly from the second grade of middle and high schools in the city of Taegu. The survey instruments were FACESⅢ, SFI-Ⅱ, State-Trait Anxiety Inventory, Depression Scale, Self-Esteem Scale, and Delinquency Scale, Factor Analysis, Cronbach's α, Multiple Regression, MANOVA, Scheffe test were conducted for the data analysis. The major findings of this study were as follows: First, OCM's and BSM's family functioning dimensions respectively had different relative influence that affected adolescent adjustment level. In anxiety and depression. BSM's family health/competence dimension had superior influence to any other family functioning dimensions and in self-esteem and delinquency, OCM's cohesion dimension was superior to any other family functions. Second, family system classification method by a new family system model using family cohesion(OCM's relationship dimension) and family health/competence(BSM's change dimension) was more useful than OCM in evaluating adolescent adjustment.

  • The human eye, constantly exposed to solar radiation, can be damaged by UV radiation. In particular, ultraviolet B (UVB)-induced damage plays an important role in retinal degeneration and cell aging. In this study, we investigated the protective effects of the methanol extract of Oxya chinensis sinuosa (OCM), an edible insect known for its high protein content (64.2%), and various pharmacological effects, on human retinal pigment epithelial cells. ARPE-19 cells were treated with OCM and subsequently UVB irradiated. Our results showed that OCM effectively attenuates UVB-induced cell damage by reducing MAPK phosphorylation (JNK and p38 MAPK). Additionally, OCM increased the phosphorylation of Akt, and cell cycle regulators, including p21 and p27, in a dose-dependent manner. Moreover, OCM treatment increased ARPE-19 cell proliferation by activating the S6K1/S6 pathway. This study suggests that OCM prevents UVB-induced retinal cell damage by increasing cell proliferation via ROS reduction, suggesting its potential as a functional therapeutic superfood against retinal cell damage.

  • Ocean Color Monitor (OCM) onboard the Indian Remote Sensing Satellite IRS-P4 has been used to retrieve chlorophyll concentration in the Bay of Bengal and the Arabian Sea using a bio-optical algorithm. Cloud masking and atmospheric corrections have been performed before applying mapping function to derive chlorophyll concentration from IRS-P4 OCM data. We have retrieved chlorophyll concentration from OCM, and MODIS during the summer and winter season along the eastern and western coast of India at every 1 degree latitude at increasing distance (25, 50, 100, 150 and 200km) away from the coast as well as near river mouths for the period 2000-2003. We have also studied spatial and temporal dynamics of monthly MODIS Aqua (for period July 2002-April 2004). The seasonal dynamics of chlorophyll concentration over the Bay of Bengal and the Arabian Sea have been discussed using OCM and MODIS for both the coastal region and the open sea.

  • This study was performed to investigate the influence of extracts from mixed culture with Tricholoma matsutake mycelium and Cordyceps militaris mycelium on hypoglycemia in streptozotocin-induced diabetic rats. Experimental animals were divided into 7 groups : normal control group(NC), diabetes control group (DC), positive control group(PC), non-fermented OCM(oriental medicine & cereal medium) extracts group (UM), crude polysaccharide of non-fermented OCM extracts group (UME), fermented OCM extracts group (UF), crude polysaccharide of fermented OCM extracts group (UFE). NC, DC groups were orally administered saline, PC group was orally administered acarbose. UM, UME, UF, UFE groups were orally administered each extract once a day for 14days. Blood glucose level was lower in the all administering OCM extract groups (UM, UME, UF, UFE) than in the diabetes group(p<0.05), and specially UF, UFE groups were similar to tendency of PC group. ALT, ALP activity in OCM groups were not significantly lowered than PC group(p<0.05). AST activity was not different with PC group. The results of this study show that extracts from mixed culture with Tricholoma matsutake mycelium and Cordyceps militaris mycelium may have a beneficial effect on the hypoglycemia.

  • The objective of this study is to analyze the present situation of compaction equipment used in the earth fill dam construction, and the compaction effects of varions types of equipment on core and pervious zones of the fill dam. The results obtained are summarized as follows; 1. Banking materials mostly used for the core zone were soils classified as CL, SC and ML, while those classified as SM, ML and SC were predominant for the pervious zone. 2. Equipments used practically in the real fields were considerably different from those specified in the designs. 3. It was found that the relationship between optimum water content and maximum dry density for both core and pervious materials showed to be linear, ranging from 10% to 25% water content. That is, ${\gamma}$dmax (core) = 2.2555-0.0284 Wopt ${\gamma}$dmax(pervious) =2.239-0.028 Wopt 4. The generalized compaction guides for all kinds of equipment and soil types consi- dered in this study may be recommended as N=8-10 T=2Ocm, N=10-12 T=3Ocm for core zone(98%) and N=6-8 T=2Ocm, N=8-10 T=3Ocm for pervious zone (95%). 5. The coefficient of permeability in the field tests showed abont 10 times as high as the laboratory test value. This large deviation, however, was due to the horizontal permeation and considered not to be significant in the light of the satisfactory compaction ratio in the field compac- tion.

  • We present a simple algorithm for detection of red patches by remote sensing in coastal waters of Korea. The red tide patches can by identified by the relative intensity of red band signal with respect to the blue-green background signal, provided the radiometric signals only in the sea area are properly stretched. We tested our algorithm by Ocean COlor Monitor(OCM) data of Indian Satellite IRS-P4, which has been received from 2001 by National Fisheries Research and Development Institute of Korea. A comparison of our results with observation shows that the locations of red tides derived from remote sending imagery by our algorithm are in accordance with observations.
