The purpose of this study is to analysis the effect of positive psychological capital on turnover intention of care worker in Long-term Care Program. Main results are as follows. First, the results identified the characteristics of the sub-factors of positive psychological capital, The efficacy, hope and resilience of care workers mostly are higher as the more married man, the longer working hours, the longer the career, the more good health condition, the more religion and more the salary. Second, total positive psychological capital is higher as the longer working hours, the more good health condition and the more the salary like sub-factors' characteristics of positive psychological capital in care workers. Third, the turnover of care worker also is higher as the longer working hours and the shorter professional career and the more unmarried. Finally, the positive psychological capital was having a negatively significant impact on turnover intention. In other words, turnover intention of the care worker is lower as the higher positive psychological capital.

Objectives : A clinical analysis was performed to provide management strategy and to improve management outcome of elderly patients with intracranial aneurysm. Patients and Methods : We reviewed medical records of 746 consecutive patients with intracranial aneurysm who were admitted from July 1991 to December 1996. They were divided into two age groups : elderly(120 patients aged 65 years or older) and non-elderly(626 patients aged 64 years or younger). We investigated the differences between the two groups in clinical characteristics, management outcome and surgical results. Results : Female(80.0%), internal carotid artery aneurysm(48.9%), poor clinical grade(Hunt and Hess Grade IV, V : 39.8%), postoperative subdural fluid collection(38.2%), and postoperative hydrocephalus(39.7%) were more frequent in the elderly patients. There were no significant differences in the incidence of hypertension, multiple aneurysm, unruptured aneurysm, rebleeding, delayed ischemic neurological deficits, postoperative hemorrhage, and low density on the postoperative brain CT scan. In some cases, surgical clipping of ruptured aneurysm could not be performed due to moribund state or refusal of surgery by the elderly patient's family. Both management outcome and surgical results in elderly aneurysm patients at 3 months after rupture were worse than those of the non-elderly group. The most common reason of unfavorable outcome was poor clinical grade in both groups, while serious medical illness causing unfavorable outcome was more common in the elderly group. Conclusion : Surgical treatment of a ruptured aneurysm should not be avoided in elderly patient solely on the basis of advanced age. If the patients are in good clinical grade, early aneurysm surgery followed by early ambulation should be recommended. Further improvements in outcome may be achieved by thorough knowledge of poor resilience of brain, CSF flow dynamics, and diminished cardiopulmonary reserve in elderly patients with intracranial aneurysm.
This paper is to analyse the necessity and development direction of the ROK's maritime security strategy white paper. To this end the paper is composed of 5 chapters titled introduction; the necessity of the ROK's maritime security strategy white paper; the ROK's actual situation in relation to maritime security strategy and cases of major advanced oceanic countries; the vision, goals, strategic tasks, and implementation system of the ROK's 'national maritime security strategy'; and conclusion. The achievement of the national marine strategic vision, such as the 'Ocean G5,' is of course possible when Korea can maintain and strengthen the maritime safety and maritime security of the people. The Sewol Ferry incident reminds us that we need a 'national maritime security strategy white paper' like the advanced marine countries. In order for the national maritime security strategy to be carried our efficiently, as in advanced oceanic countries, mere should be a dedicated department with sufficient authority and status to mobilize the cooperation of related organizations including naval-coastal cooperation. It would be good to set up a tentatively named Maritime Security Council, an organization of minister-level officials involved under the National Security Council, and an executive body composed of working-level officials from related ministries. In order to successfully carry out the national maritime security strategy for the maritime safety and maritime security of the people like the United States and the United Kingdom, we need to further strengthen our domestic cooperation and cooperation system, international cooperation, and maritime security. We have to promote the establishment and promotion of maritime security strategies by the Navy; strengthening the operational link between the Navy and the Coast Guard; strengthening the maritime surveillance capability at the national level, and promoting sharing with the private sector, etc.
As an exploratory research on China's animation, this study aims to enhance an understanding of the trends and characteristics of China's animation through examining its history and to forecast its future development trajectory. From its founding to recent period, China tried to maintain Communist political system through imbuing national identity to its people through management and supervision of media products under direct government's leadership in combination with ideological education. Such policy was also implemented in animation, major audience of which is children. With regard to the introduction of the policy and its influence, five historical phases could be identified as follows. During the first phase, from the founding of the Republic until the Cultural Revolution, national culture was introduced to China's animation. The second phase, which corresponds with the Cultural Revolution period, marks the decline of national culture. National culture was reemphasized during the third phase that follows the Cultural Revolution, which led to the nomination of the 'China school,' followed by the fourth phase, during which China's animation suffered the second decline due to the spread of TVs and foreign animation imports. Reintroduction of national culture on China's animation in the context of rapid industrialization process before and after 2000 characterizes the recent phase. It can be expected that although there could be some change in methods and forms, China's animation, which introduced national culture from its inception and maintained remarkable resilience following the period of decline, will continuously stress the its own national cultural identity.

Spectrum spreading, in its general form, can be conceived as an artificial expansion of the signal bandwidth with respect to the minimum Nyquist band required to transmit the desired information. Spreading can be functional to several objectives, including resilience to interference and jammers and reduction of power spectral density levels. In the paper, signal spreading is manly used for increasing the received energy, thus satisfying link budget constraints, for terminals with low aperture antennas, without increasing the transmitted EIRP. As a matter of fact, in many mobile scenarios, even when MODCOD configurations with very low spectral efficiency (i.e. QPSK-1/4) in DVB-S2 standard, are used, the link budget cannot be closed. Spectrum spreading has been recently proposed as a technique to improve system performance without introducing additional MODCOD configurations under the constraint of fixed power spectrum density level at the transmitter side. To this aim, the design of spectrum spreading techniques shall keep into consideration requirements such as spectrum mask, physical layer performance, link budget, hardware reuse, robustness, complexity, and backward compliance with existing commercial equipments. The proposed implementation allows to fully reuse the standard DVB-S2 circuitry and is inserted as an 'inner layer' in the standard DVB-S2 chain.

The purpose of this study was to analyze research trends on trauma in maritime police officers and police officers in Korea and suggest future research directions. We collected 57 studies related to trauma in maritime police and police from Korean Citation Index listed journals and analyzed basic information, subjects, research methods, measurements and related variables. The results showed that studies have been conducted sporadically from 2010 and only six out of the 57 studies were conducted for maritime police officers. Police administration (59.6 %) was the most common area of researchers' major, followed by psychology (19.3 %), medicine and nursing (10.5 %), social welfare (8.8 %) and education(1.8 %). Five out of the six maritime police studies were conducted in the police administration field. Most of the studies adopted the quantitative research method (78.9 %). Only three studies adopted the qualitative method, all of which targeted police officers. The IES-R-K was the most used PTSD scale, followed by the PDS and the PCL-5. Trauma-related variables were commonly conducted in the order of traumatic event experience, resilience, stress-coping methods and social support. Finally, the implications of the findings of our study and the suggestions for further research were discussed.
The tropical wet evergreen, tropical semi evergreen and moist deciduous forest types are projected to be impacted by climate change. In the Western Ghats region, a biodiversity hotspot, evergreen forests including semi evergreen account for 30% of the forest area and according to climate change impact model projections, nearly a third of these forest types are likely to undergo vegetation type change. Similarly, tropical moist deciduous forests which account for about 28% of the forest area are likely to experience change in about 20% of the area. Thus climate change could adversely impact forest biodiversity and product flow to the forest dependent households and communities in Uttara Kannada district of the Western Ghats. This study analyses the distribution of non-timber forest product yielding tree species through a network of twelve 1-ha permanent plots established in the district. Further, the extent of dependence of communities on forests is ascertained through questionnaire surveys. On an average 21% and 28% of the tree species in evergreen and deciduous forest types, respectively are, non-timber forest product yielding tree species, indicating potential high levels of supply of products to communities. Community dependence on non-timber forest products is significant, and it contributes to Rs. 1199 and Rs. 3561/household in the evergreen and deciduous zones, respectively. Given that the bulk of the forest grids in Uttara Kannada district are projected to undergo change, bulk of the species which provide multiple forest products are projected to experience die back and even mortality. Incorporation of climate change projections and impacts in forest planning and management is necessary to enable forest ecosystems to enhance resilience.

This study was carried out to elucidate the relation between water quality and structure of the aquatic ecosystem in the agriculture reservoir Otae-ji from January to December in 2009. The proportion of forest was 46.98%, which means that non-point sources are major contributor of water pollution in this area. The annual mean COD(Chemical Oxygen Demand) in Otae-ji was $3.6mgL^{-1}$, indicating, level II of environmental standards and the trophic state was mesotrophic. Although total phosporus concentration in the reservoir was high in August due to large inflow of nutrients from outside the reservoir during monsoon season, there was no break out of significant algal bloom in the summer. The seasonal succession of phytoplankton showed that the dinophyta dominated in the the spring, chlorophyta in the summer, chrysophyta and chlorophyta in the autumn and chrysophyta in the winter. In case of zooplankton, rotifers dominated in the most seasons, but cladoceran(Bosmina longirostris) dominated in June and copepod(Nauplii) in August. The macrophyte plants showed diverse species compositon consisted of 3 varieties, 24 species, 23 genera, 15 families and 14 orders. The macroinvertebrates also showed various FFG(Functional Feeding Groups) such as GC(Gathering-Collector), P(Predator), SH(Shedder), FC(Filter-Collector) and PP(Plant-Piercer). Ecosystem stability analysis using aquatic insects was classified as Group I, which has high resilience and resistance indices. A total of 14 species of fish was collected but exotic species such as Lepomis macrochirus and Micropterus salmoides were not found in Otae-ji. In conclusion, the preservation of healthy food wed in the reservoir ecosystem is closely related to water quality management as well as effective prevention of algal bloom by helping good material circulation in aquatic ecosystems.

The purpose of this study was to evaluate the physicochemical and sensory characteristics of white bread and added 2%, 4%, 6%, or 8% Hallabong powder. Dough pH of the control group was 5.65, and it decreased as increasing amounts of Hallabong powder were added. Also, total titratable acidity of dough significantly increased with increases in Hallabong powder. The fermentation power and dough expansion significantly increased with increasing incubation time; the control was highest at 98.67%. White bread pH, specific volume, and baking loss decreased significantly as with increased Hallabong powder content. The bread moisture content was not significantly different between samples, differing only from 40.61~41.83%. Water activity was 0.960 Aw in the 6% Hallabong powder mixture, which was the highest in samples. In color, lightness of crust significantly decreased with increased Hallabong powder content, whereas redness showed the reverse effect. Lightness of crumbs significantly decreased, with increased Hallabong powder content, whereas redness and yellowness showed the reverse effect. In texture, hardness and fracturability significantly increased, while resilience showed the reverse effect. In the sensory evaluation, citrus flavor, bitterness, astringency, and off-flavor significantly increased with increased Hallabong powder content, and the control sample showed the highest score in color, flavor, softness and overall acceptability. The 2% and 4% samples showed more than average scores. Based on these results, Hallabong powder could be considered a functional material. The optimum amount of Hallabong powder to add for baking bread would be 2~4%.

This study investigated the quality of noodles added with different amounts of freeze-dried fish scale collagen mixture powder (FDCMP). Freeze-dried fish scale collagen mixture was prepared by mixing ingredients (fish scale collagen : herb extracts : dextrin : distilled water=1:0.75:0.25:2), which were freeze-dried. Noodles were prepared by adding 0.5, 1.0, 1.5, and 2.0% (w/w) FDCMP based on flour weight. Cooked noodle weight and volume decreased with increasing amount of FDCMP, whereas turbidity of soups significantly increased. The water-binding capacity of FDCMP was higher than that of flour. Uncooked and cooked noodles showed reduced L values as well as increased a and b values increasing amount of FDCMP in the flour composite. Hardness and chewiness of cooked noodles significantly decreased with increased FDCMP content. Adhesiveness, cohesiveness, and gumminess increased with increased FDCMP content. Springiness and resilience were not significantly different between the control and FDCMP group. Finally, sensory evaluation results indicated that texture, mouthfeel, and overall preference of noodles containing 0.5% FDCMP were higher compared to those of the other samples. Based on cooking properties and sensory evaluation, freeze-dried fish scale collagen mixture powder up to 0.5% could be substituted for wheat flour to improve noodle quality.
