Purpose - The purpose of this study is to identify the relations among perceived organizational support, career planning, and subjective career success (career satisfaction and job satisfaction). In particular, this study focuses on the mediating effect on the career planning between perceived organization and subjective career success. The target cases are employees of a Korean branch of a global company (A), which operates formal career program to support a career development for employees. Research design, data, and methodology - The data were collected from December, 2014 to March, 2015. 211 out of 300 questionnaires were returned (response rate 70.3%). After the data cleaning, 209 questionnaires were used for the data analysis. These data were analyzed through descriptive statistics, correlation analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and structural equation modeling (SEM). The whole process of the data analysis was accomplished using the SPSS 21.0 for windows and the AMOS 21 program. Results - The findings of the study are as follows: First, the better the organizational support is perceived, the higher career satisfaction and job satisfaction is. That is, the employees' career and job satisfaction is higher, when they feel themselves received more supporting. Second, perceived organizational support has a positive impact on employees' career planning. This result means that it is important to support employees in their career development. Third, career planning has a positive impact on career satisfaction, but not on job satisfaction. Lastly, it is verified that career planning has a mediating effect between the perceived organizational support and career satisfaction. Not only has the perception of an organizational support a direct impact on career satisfaction, but also an indirect impact through career planning. However, there is not an indirect relationship through career planning, just an direct relationship between the perception of an organizational support and job satisfaction Conclusions - Based on the findings of this study, the major conclusion of the study was as follows: The study provides theoretical values and practical implications for the fact that the differences of the subjective perception about organizational support exist among employees, and the differences have an impact on their career planning as well as subjective career success. Furthermore, some recommendations for workplace were suggested: The companies should support the career development for employees in organization level. Even though employment instability makes individual workers themselves to be responsible for their own career development, it is an important issue in organizational level that employees' career success could have positive effects on organizational development and success, as well. However, there is a limit in the study that analyzing results cannot be generalized due to the data from a single company. Some recommendations for future research are suggested: First, a comparative study should be conducted with other various companies. Second, a hierarchical analyzing model needs to be applied to substantiate how organizational context influences on subjective career success of employees.

In the present knowledge and information society, every citizen can enjoy benefits of various advanced technologies such as information and communication technology(ICT) and smart technology. Nowadays everybody has to have some level of information literacy and application ability in order to enjoy benefits from various advanced technologies. In additions, knowledge and practice will about information and communication ethics are also required for all. Currently we need some kind of standards to evaluate and model everybody's information literacy and application capability. In this sense, information culture index has been developed to check information literacy and application capability of every citizen for various aspects of daily life. Information culture index consists of three standards, that is, application, awareness, and norm, respectively. Application standard indicates how information contents and skills are generalized for all. In other words, it is concerned with how every citizen can understand information literacy and use information skills in his or her daily life. Awareness standard is concerned with how well everyone can respect and trust others in the current information culture community. Norm standard is concerned with how everyone can use information communication services according to his or her desirable sense of information and communication ethics. The purpose of this paper is to analyze correlation between academic background and three standards of information culture index, that is, application, awareness, and norm. For this purpose, we use 2-year national survey works for information culture. After thorough statistical analysis, we can conclude that, awareness and norm standards do not show a meaningful correlation with academic background while application standard shows a meaningful correlation with academic background, It means that, the higher academic background one has, the higher application standard one can achieve. We expect that our correlation analysis results can be helpful to spread of information education and information culture in the future.

AVO and complex trace analyses mainly used to characterize natural gas reservoir were tested in this paper for a possible application to detection of major geological discontinuities such as fracture zones. The test data used in this study were calculated by utilizing a viscoelastic numerical program which was based on the generalized Maxwell body for a horizontal fracture model. In AVO analysis of a horizontal fracture zone, p-wave reflection appears to be variant depending upon the acoustic-impedence contrast and the offset distance. The fracture zone is also effectively clarified both in gradient stack and range-limited stack in which fracture zone reflection is attenuated with the increasing offset distance. In complex attribute plots (instantaneous amplitude, frequency, and phase), the top and bottom of the fracture Tone are characterized by a zone of strong amplitudes and an event of the same phase. Low frequency characteristics appear at the fracture zone and the underneath. Amplitude attenuation and waveform dispersion are dependent on Q-contrast between the fracture zone and the surrounding media. They were properly compensated by optimum inverse Q-filtering.

A series of three-dimensional numerical simulations using a generalized multidimensional hydrodynamic dispersion numerical model is performed to simulate effectively and to evaluate quantitatively impacts of fault existence on densitydependent groundwater flow and salt transport in coastal aquifer systems. A series of steady-state numerical simulations with calibration is performed first for an actual coastal aquifer system which contains a major fault. A series of steadystate numerical simulations is then performed for a corresponding coastal aquifer system which does not have such a major fault. Finally, the results of both numerical simulations are compared with each other and analyzed. The results of the numerical simulations show that the major fault produces hydrogeologically significant heterogeneity and true anisotropy in the actual coastal aquifer system, and density-dependent groundwater flow, salt transport, and seawater intrusion patterns in the coastal aquifer systems are intensively and extensively dependent upon the existence or absence of such a major fault. Especially, the major fault may act as a pathway for groundwater flow and salt transport along the direction parallel to its plane, while it may also behave as a barrier against groundwater flow and salt transport along the direction perpendicular to its plane.

Recently renewable energy such as offshore wind energy takes a higher interest due to the depletion of fossil fuel and the environmental pollution. This paper deals with multi-body dynamics (MBD) analysis technique for offshore wind turbine system considering aerodynamic loads and Thevenin equation used for determination of electric generator torque. Dynamic responses of 5MW offshore wind turbine system are evaluated via the MBD analysis, and the system is the horizontal axis wind turbine (HAWT) which generates electricity from the three blades horizontally installed at upwind direction. The aerodynamic loads acting on the blades are computed by AeroDyn code, which is capable of accommodating a generalized dynamic wake using blade element momentum (BEM) theory. In order that the characteristics of dynamic loads and torques on the main joint parts of offshore wind turbine system are simulated similarly such an actual system, flexible body modeling including the actual structural properties are applied for both blade and tower in the multi-body dynamics model.

International Maritime Organization made International Convention for the Safety of Life at Sea to require all ships to carry official charts, both paper and electronic, and is especially encouraging the use of Electronic chart display and information system (ECDIS). Recently, the argument that all Electronic Charts(ENC) displayed in ECDIS should be distributed through Regional ENC Coordinating Center is being raised within the IHO. The use of ECDIS was generalized, but the existing two RENCs in Europe are thought to be not enough. Especially, East Asian region, due to its rapid growth in economy and marine traffic, RENC is found necessary. This research establishes the legitimacy and strategy of East Asian RENC by defining the roles of RENC based on the IMO ECDIS Mandatory Carriage Requirement and RENC operation status through suggesting a "Phase-In" RENC model, which was built upon the strategy of East Asian Hydrographic Commission(EAHC).

Purpose - Satisfaction with service is evaluated according to customers' subjective judgment. The expected value of customer service and its evaluations depend on the customers' position. The customer recognizes two different forms of service levels. One is satisfaction and the other is dissatisfaction. Customers who are satisfied want to receive the service in future. However, those dissatisfied try to change the service. The service provider tries to improve the service. There are two different service cycles. One is the successful cycle and the other is the failure cycle. This study aimed to empirically determine the effects of the justice and authenticity of service recovery on customer behavioral intention through an integrated approach to cognitive justice and psychological authenticity. Research design, data, and methodology - Based on a literature review, justice of service recovery was categorized into three types: distributive, procedural, and interactive. Then, authenticity was added to obtain four independent variables, along with recovery satisfaction as a parameter. Behavioral intention, as an outcome variable, was divided into the repurchase intention and positive word-of-mouth. The model and hypotheses were created and measurement items were developed. A questionnaire survey of items concerning the service recovery experience at family restaurants was conducted on college students and residents in Gwangju from September 30 to October 31, 2013. A total of 400 copies of the questionnaire were sent out and 385 were returned. Respondents answered questions about the importance of, and satisfaction with service recovery on a 5-point Likert scale. Excluding 174 copies without service failure experiences and 7 inappropriate copies, 204 copies were analyzed using SPSS 21.0 for Windows and AMOS 20.0 to determine the reliability and validity of measurements. The hypotheses were tested through a goodness-of-fit analysis. Results - First, distributive justice positively affected recovery satisfaction. Second, procedural and interactive justice had no impact. Third, authenticity positively affected recovery satisfaction. Fourth, distributive justice had relatively stronger effects on recovery satisfaction than authenticity. Fifth, recovery satisfaction significantly affected repurchase intention and positive word-of-mouth and it proved effective in mediation. Finally, additional analysis was performed for descriptive statistics of the principal variables by various demographic characteristics and significant differences were found in gender, occupation, and so on. Conclusions - This study has academic significance as the fairness and authenticity of service recovery were investigated to reveal the effects on behavior. The findings could be applied to a wide range of service recovery strategies. However, there are some limitations. First, data was collected only from the residents of Gwangju and most respondents were aged 20-30. Future studies should target a wide range of areas and age groups. Second, because the questionnaire used in this study targets only convenience family restaurants, the results of this study cannot be generalized to all services companies. Future research should be done on a wide range of industries such as hotels, airlines, and hospitals, and perform a comparison between sectors.

Alteration in the syntesis or enhanced inactivation of nitric oxide(NO) can induce impairment of endothelial cell function. Insulin dependent diabetes mellitus(IDDM) is characterized by impaired endothelial function and vascular disease. NO is produced through L-arginine pathway To elucidate the hypothesis that the decreased production on NO in IDDM reflects vascular damage and the NO production can be manipulated by either dietary fat(7% of kg diet) or the oral supplementation with L-arginine(2g/kg bw), plasma markers for vascular endothelial damage and plasma lipid profiles were measured in streptozotocin(STZ)-induced diabetic rats. Diabetic or normal Sprague-Dawley rats were fed 6 different experimental diets for 4 weeks(SO : soybean oil, SOA: soybean oil + L-arginine supplementation, BT : beef tallow, BTA_ beef tallow + L-arginine supplementation, OV olive oil, OVA : olive oil + L-arginine supplementation). Plasma glucose, total cholesterel, HDL-cholesterol, LDL-cholesterol and triglyceride were measured. Endothelial markers, plasma von Willebrand factor(vWf), thromboxane B$_2$, and 6-keto PGF1$\alpha$ of aorta were measured by ELISA. Plasma NO production was evaluated through the measurement of nitrite by EIA. Feeding saturated fatty acid(SFA, BT) increased relative liver size(RLS) in diabetic rats compared to either polyunsatunted fatty acid(PUFA, SO) or monounsaturated fatty acid(MUFA, OV) The supplementation of L-arginine inhibited the liver and kidney enlargement in olive oil find diabetic rats. Plasma glucose was lower in diabetic animal find the olive oil compared to fed beef tallow and the supplementation L-arginine decreased it in diabetic rats find beef tallow significantly(p < 0.05). Plasma TXB$_2$ levels were increased due to diabetes and the value of beef tallow group showed highest value. Plasma vWf concentration of beef tallow group was higher value in normal rats and was elevated more in diabetes. In diabetic groups, the vWf concentration of olive oil group was lower than beef tallow or soybean oil group. The supplementation of L-arginine in diabetic rats decreased plasma TXB$_2$ and vWf levels significantly(p < 0.05). NO production was higher in normal olive oil fed rats and was tend to be decreased in diabetic rats and the supplementation of L-arginine recovered to normal value(p < 0.05), Olive oil supplemented with L-arginine tended to lower plasma total cholesterol and LDL-cholesterol after 4 week treatment. These results suggest that generalized vascular endothelial changes based on plasma TXB$_2$and vWf occurs in diabetic rats. and olive oil with L-arginine supplementation contributes to a better control of the hyperglycemia, endothelial changes and hypercholesterolemia accompanying diabetes as compared with beef tallow or soy bean oil in this rat model.

Background: The predictive value of the xeroderma pigmentosum group D (XPD) Lys751Gln polymorphism regarding clinical outcomes of patients with colorectal cancer (CRC) receiving oxaliplatin-based chemotherapy has been evaluated in numerous published studies, but the results remain inconclusive. Therefore, we performed a meta-analysis to determine the precise role of the XPD Lys751Gln polymorphism in this clinical situation and optimize individual chemotherapy. Materials and Methods: A multiple search strategy was used to identify eligible studies. Pooled odds ratios (ORs), generalized odds ratio (ORG) and their 95% confidence intervals (CIs) were used to estimate the objective response, while hazard ratios (HRs) with 95%CIs were used for progression-free survival (PFS) and overall survival (OS). Results: A total of 17 studies including 2,286 patients met the inclusion criteria. Overall, the XPD 751Gln allele was associated with a non-significant reduced objective response to oxaliplatin-based chemotherapy in all patients or in the Asian and Caucasian subgroups. However, poor PFS and OS of CRC patients treated with oxaliplatin-based regimens were significantly related to the XPD 751Gln allele in the dominant model (PFS: HR=2.10, 95%CI: 1.65-2.67; OS: HR=3.18, 95%CI: 1.57-6.47). On stratified analysis by ethnicity, these relationships were more pronounced in Asians (PFS: HR=2.49, 95%CI: 1.79-3.47; OS: HR=5.25, 95%CI: 3.46-7.94) than in Caucasians (PFS: HR=1.73, 95%CI: 1.22-2.46; OS: HR=1.78, 95%CI: 1.06-2.99). Conclusions: The XPD Lys751Gln polymorphism may have prognostic value in patients with CRC undergoing oxaliplatin-based chemotherapy.

The main purpose of this paper is to propose a general dialogue flow in 'the a appointment scheduling dialogues' in German using the concept of dialogue acts. A basic a assumption of this research is that dialogue acts contribute to the improvement of a translation system. They might be very useful to solve the problems that syntactic and semantic module could not resolve using contextual knowledge. The classification of the dialogue acts was conducted as a work of VERBMOBIL project and was based on real dialogues transcribed by experts. The real dialogues were analyzed in terms of the dialogue acts. We empirically analyzed the sequences of the dialogue acts not only in a series of dialogue turns but also in one dialogue turn. We attempted to analyZe the sequences in one dialogue turn additionally because the dialogue data used in this research showed some difference from the ones in other existing researches. By examining the sequences in dialogue acts. we proposed the dialogue flowchart in 'the a appointment scheduling dialogues' 'Based on the statistical analysis of the sequences of the most frequent dialogue acts. the dialogue flowcharts seem to represent' the a appointment scheduling dialogues' in general. A further research is required on c classification of dialogue acts which was a base for the analysis of dialogues. In order to e extract the most generalized model. we did not subcategorize each dialogue acts and used a limited number of items of dialogue acts. However. generally defined dialogue acts need to be defined more concretely and new dialogue acts for specific situations should be a added.
