Objectives: The objective of this study is to evaluate the correlates of depression and perception gap of adolescents' Health-Related Quality of Life (HRQOL) between Parents and Children. Methods: Research targets are all students and their parents who are enrolled in from 1st~3rd grade of middle school to $1^{st}$ grade of high school which was selected intentionally. The survey was conducted from May $16^{th}$ to June $9^{th}$ in 2014 by research staffs equipped with structured questionnaire. $PedsQL^{TM}4.0$ Generic Core Scales and Korean form of the Kovacs' Children's Depression Inventory were the main tool for measuring the HRQOL and depression. Data of 985 respondents, both of parents and children, was used for analysis of this study. Results: In terms of gender difference of depression, 5.8% of adolescents, 3.2% of male and 8.5% of female (p<0.001), are shown depression symptom. Depression rate of the low level students of academic achievement was 11.0% which is the lowest rate to compare to 4.3% of middle level and 2.6% of high level students (p<0.001). The case that parents overestimated their children's overall HRQOL is 3.699 times more likely to have depression symptom than the case which is in concurrence between parents and children. Especially the overestimation in social, emotional, and academic area of HRQOL promote depression 3.918 times, 3.371 times, and 2.258 times more than the agreement occurred of each areas. In contrast underestimation in physical area of HRQOL reduce depression 0.266 times less than the agreement occurred of the area. Conclusion: The perception gap of adolescents' HRQOL between parents and children is the most influential factor to adolescents' depression among all variables which was evaluated in this study.

Purpose: The purpose of this study was to examine the effect of a discharge education program on maternal role confidence and parenting stress of mothers who delivered premature infants. The program provided them with information on childrearing and supportive educational nursing care. Method: This study was based on pretest-posttest nonequivalent nonsynchronized quasi-experimental design. The participants in this study were 30 mothers who delivered premature infants at a general hospital in G city. The instruments used in this study were Maternity Confidence Inventory, Parenting Stress Index(PSI). Results: The first hypothesis that the mothers in the experimental group would undergo changes in maternal role confidence after the intervention was accepted, as there was a statistically significant gap between the two groups(F=9.386, P=.000). The second hypothesis that mothers in the experimental group would undergo change in parenting stress after the intervention was accepted, as there was a statistically significant gap between the two groups(F=4.425, P=.380). Conclusion: The findings suggest that the Discharge Education Program was an efficient intervention method to boost the maternal confidence of mothers with premature infants and to decrease their parenting stress.

Purpose: This study compared the importance and performance of rehabilitation nursing needs perceived by stroke patients and nurses. Methods: A total of 275 subjects were divided into two groups. One group was 136 stroke patients and the other was 139 nurses. Data were collected with the Rehabilitation Nursing Service Inventory. The data were analyzed by t-test and ANOVA using the SPSS/WIN 21.0 program. Results: The degree of importance and performance in rehabilitation nursing needs perceived by the stroke patients were $3.69{\pm}0.47$ and $3.48{\pm}0.50$, respectively, showing a significant difference (t=21.04, p<.001). The degree of importance and performance perceived by nurses were $3.84{\pm}0.42$ and $3.60{\pm}0.45$, respectively, showing a significant difference (t=26.53, p<.001). A significant difference in the degree of importance and performance in rehabilitation nursing needs was also observed between stroke patients and nurses (t=-2.78, p=.006; t=-2.12, p=.035). Conclusion: These findings showed that there was a perception gap between stroke patients and nurses. Therefore, it will necessary to identify methods for reducing this perception gap and developing rehabilitation nursing intervention considering the rehabilitation nursing needs of stroke patients.

This paper investigates and selects the areas that need to be improved in R&D and production management of small and medium size companies. The study on the capability of R&D and production management shows that the areas for evaluating of the R&D and production management levels are composed of 8 elements : R&D resource, R&D support and experience, long-term operations strategy, intermediate range planning, short-term planning, subcontractor management, logistics and inventory management, and quality management. The investigation of the gap between the importance of the areas and the capability of SMEs shows that the most important things are to consolidate supply chain, to improve product and process competitiveness using quality improvement, and to enhance production management through sophisticated short-term planning. The detailed analysis also shows that the areas that need to be improved depend on the size and sales of the company.

Supermarket Franchising, as a relatively new mode of retail business, is often regarded as one of the two hallmarks of the "Modern Logistics Revolution". After more than ten years of development, franchise supermarkets have been a rising force in retail business in China. As a product of a highly-developed commercial economy, franchise supermarkets mainly deals in foodstuffs and other daily necessities, featuring low cost, high turnover rate, low prices and diversified inventory. Propelled by the conveniences that come with open shelves and self-service shopping, franchise supermarkets have been growing very rapidly and the rise of many franchise supermarket brands bears testimony to its growth potential and profitability. Meanwhile, in the backdrop of this boom, some franchise supermarkets are going bankrupt. This paper analyzes the current status of franchise supermarkets and some factors bearing on their core competencies, so as to close the competitiveness gap with international retail giants.

To identify the effect of engineered barriers on the leach rate of cesium from spent PWR fuel under a synthetic granitic groundwater, the related leach tests with and without bentonite or metals have been performed up to about 6 years. The leach rates were decreased as a function of leaching time and then became a constant after a certain period. The period in a bare spent fuel was much longer than that with bentonite or metal sheets. The cumulative fraction of cesium released from the spent fuel with bentonite or with copper and stainless steel sheets was steadily increased, but the fraction from bare fuel was rapidly and then sluggishly increased. However, the values deducted its gap inventory from the cumulative fraction of cesium released from the bare fuel was almost very close to the others. These suggest that the initial release of cesium from bare fuel might be dependant on its gap inventory and the effect of engineered barriers on the long-term leach rate of cesium would be insignificant but the rate with engineered barriers could be reduced in the initial transient period due to their retardation effect. And the long-term leach rate of cesium from spent fuel in a repository would be approached to a constant rate of $2\times10^{-2}g/m^2-day$.

This study, by adopting case study methodology, is focused on examining the present state and analyzing the cause of the digital divide, and suggesting policies for bridging the divide, specifically in view of SMEs. We have taken cases of manufacturing companies, visiting and interviewing 18 SMEs in 10 APEC member economies which show sharp difference in usage of ICT. In order to analyze the digital gap among SMEs, we used 5 variables that are composed of computer hardware, computer software, Internet, readiness of ICT, and performance of ICT adoption, while categorizing the cases into low and high tier based on the national ICT index. From a computer hardware perspective, the high tier (0.66) has almost double the number of PC’s per employee, compared with the low tiers (0.34). This gap can be explained by financial availability of low income and high tariff in the developing economies. In the computer software perspective, the SMEs in the low tier had some restrictive use of computer applications such as financial and accounting management and document management, while those in the high tier enjoyed more diversity in the use of applications such as inventory management, sales management, financial and accounting management, procurement management, CRM, and ERP. In view of the readiness of ICT, the difference in ICT infrastructure and financial status between the low and high tier was far wider than any other variables. As a result of ICT adoption, SMEs benefited in view of learning and growth, internal business processes, customer service, and financial affairs. To effectively bridge the digital divide between the low and high tier, actions such as setting up a secondary market of used computers among cooperating developed and developing countries, developing and diffusing good business applications, and building speedy, low-cost telecommunication infrastructures should be taken.

Since national GHG reduction target by 2020 has been presented in Korea, the role of railroad has been reinforced within transport system due to the allocation of reduction target into sector. So, it is necessary to manage activity data systematically for the calculation of GHG emission in railroad. Now, the activity data of diesel consumption for NIR(National Inventory Report) are provided from oil supply and demand statistics. On the other hands, the activity data collected directly from railroad operating companies are used for GHG & Energy Target Management Act. This study aimed to assess the GHG emissions using two kinds of activity data related to the diesel consumption of railroad in 2009 and 2010. As a result, GHG emissions based on oil supply and demand statistics was 636 thousands ton $CO_{2e}$, but the activity data collected from railroad operating companies showed 649 thousands ton $CO_{2e}$ in 2009. Also, the gap of $CO_{2e}$ emission was increased in 2010. These trends were caused because oil supply and demand statistics included total diesel sales volume during 1 year and the activity data collected from railroad operating companies were the amount of diesel consumption only at railcar operation and maintenance step. In conclusion, it is important to develop the management and verification system of activity data with high reliability to substitute oil supply and demand statistics in railroad sector.

Purpose - Today's world is rapidly changing due to swift changes in organization's infrastructures and supply chain is becoming an important factor which affects the organization's global competitiveness. Research design / data / methodology - Researchers indicated that environment uncertainty is considered an external driving force to establish a unique supply chain. Market competition, reducing the gap of performance and quality between the products are compelling the practitioners and researcher to change the paradigm of managing the business processes effectively and efficiently. Results - In old times, supply chain of any organization was measured on the basis of inventory turns, defect rats, lead times, stock buffering and service level. But, Lee H.L. in 2004, published an article in Harvard Business Review who proposed three A (Adaptable, Agile and Aligned) termed as "Triple-A" of successful supply chain. Conclusions - He claimed that organizations can compete through the creation of Triple-A supply chain. Hence, the basic aim of this review paper is to develop basic insights regarding what is Triple-A of supply chain, its importance and functioning in today's competitive world.

In this paper, probabilistic seismic performance assessment of a typical non-seismic RC frame building representative of a large inventory of existing buildings in developing countries is conducted. Nonlinear time-history analyses of the sample building are performed with 20 large-magnitude medium distance ground motions scaled to different levels of intensity represented by peak ground acceleration and 5% damped elastic spectral acceleration at the first mode period of the building. The hysteretic model used in the analyses accommodates stiffness degradation, ductility-based strength decay, hysteretic energy-based strength decay and pinching due to gap opening and closing. The maximum inter story drift ratios obtained from the time-history analyses are plotted against the ground motion intensities. A method is defined for obtaining the yielding and collapse capacity of the analyzed structure using these curves. The fragility curves for yielding and collapse damage levels are developed by statistically interpreting the results of the time-history analyses. Hazard-survival curves are generated by changing the horizontal axis of the fragility curves from ground motion intensities to their annual probability of exceedance using the log-log linear ground motion hazard model. The results express at a glance the probabilities of yielding and collapse against various levels of ground motion intensities.
