The objective of this paper is to verify the association among IOS utilization, relationship quality, and firm performance. Based on the literature review, we configure a research model and verify the research hypothesis by utilizing structural equation modeling with data collected from 340 domestic manufacturers. The results of SEM are as follows. First, IOS utilization has a positive effect on satisfaction and firm performance. Second, satisfaction has a positive influence on trust and commitment, and trust positive affect commitment. Third, satisfaction and commitment has a positive effect on firm performance, but trust has not significantly affect firm performance. Finally, commitment plays a role of mediator in the association between trust and firm performance. The implication of this paper is to verify that ISO utilization is an important factor to improve the performance in B2B transaction. However, it is necessary to derive a more precise implication by considering diverse environment faced by each company in future research.

This study endeavors to propose factors that should be intensively managed by using an IPA model to analyze the strengths of military logistics. Based on the improvement measures, we constructed a questionnaire with 5 points of Likert scale and analyzed the importance and satisfaction through SPSS 23. Examination of several evaluation factors revealed 'expansion of and modernization storage facilities' as the most important factor, 'merger and abolition of regional logistics work' (3.56) had the highest satisfaction level. Factors involving the expansion and modernization of the storage facilities showed the largest difference between importance level and satisfaction level, at 2.01. This indicates the necessity for an overall review of the expansion and modernization of storage facilities related to military logistics. This study aims to identify the areas that should be improved firstly in military logistics and concentrate on management to create more effective results. Thus it suggests that this study has a concentration on management for the streamlining of military logistics.

Early age at menarche, which is indicator of early biological maturity, has been shown to be associated with increased adult body mass index. Early menarche has also been associated with many cardiovascular disease risk factors and metabolic syndrome. To evaluate the impact of menarche to cardiovascular risk factor, we assessed by age at menarche, brachial-ankle pulse wave velocity (baPWV), which represents arterial stiffness, in women with or without metabolic syndrome. The subjects recruited for this study were three hundred one women. Relatively early menarche and relatively late menarche were classified according to less than $50^{th}$ percentile for relatively early menarche, and great than the $50^{th}$ percentile for relatively late menarche. Subject were divided four group, 1) women who had not adulthood metabolic syndrome and relatively early menarche, 2) women who had not adulthood metabolic syndrome and relatively late menarche, 3) women who had adulthood metabolic syndrome and relatively early menarche, 4) women who had adulthood metabolic syndrome and relatively late menarche. Women who had a relatively early menarche with adulthood metabolic syndrome had significantly high levels of blood pressure, triglyceride, fasting insulin and homeostatic model assessment of insulin resistance (HOMA-IR) levels than women with late menarche with adulthood metabolic syndrome, and had significantly lower HDL-cholesterol levels. And also, women who underwent a relatively early menarche with metabolic syndrome had highest level of baPWV in adult. In this study we found effect of age at menarche on adulthood metabolic risk factors for cardiovascular disease (e.g., baPWV, insulin resistance, hyperlipidemia) in Korean women.

The aim of this research is to propose the final shirt design modified for new senior women that fulfills their emotional and physical needs. The modifications were based on the results of in-depth interviews and literature search, and the study was conducted in order to understand the desires and preferences of senior women, as consumption of outdoor-wear by the group continues to increase. To develop the design of outdoor-wear that satisfies the physical and emotional qualities and preference of the new senior women, six different designs with lines, combined materials, as well as materials that were layered, pleated and draped were proposed using virtual-dressing simulation software. Then, the modified designs were derived from the six original designs by reflecting the opinions collected in the in-depth interviews with eleven women in their 50s. The responses in the interviewed showed a preference for lines, pleats and layers, as these features made the clothes look trendy, gave it a slender-look, and improved the body shape of the women. As the color is the critical factor for outdoor-wear, there was an overwhelming preference for primary colors by the women, which was in contrast to their color preference in general clothes. A sleeve design modification was proposed to convert the half-sleeves to 3/4-long sleeves in order to account for changes in body temperature at menopause, and to satisfy the aesthetic needs for covering wrinkles. Research of new senior outdoor-wear designs will help segment and differentiate strategies for the increasingly fierce competing outdoor market, as well as l provide directions in the design creation process using the simulation of 3D virtual model.

This study was conducted to investigate how consumer global-mindedness affects global fashion out-of-home (OOH) advertising which global consumer culture positioning applies, and to examine the relations among global fashion brand OOH advertising, perceived fashion brand globalness, perceived quality and brand reputation. Data were collected from 238 general people in 20~30s in seoul and were analyzed by using statistic methods such as frequency analysis, reliability analysis, confirmatory factor analysis and structural d modelling by running both SPSS 18.0 and AMOS 7.0 program. The results of this study were as follows. First of all, it indicated that the fit indexes were satisfied and the overall model of this study showed a favorable goodness of it from the results of confirmatory analysis. Secondly, consumer global-mindedness had a positive impact on preference towards global fashion OOH advertising. Finally, preference towards global fashion brand OOH advertising positively affected perceived fashion brand globalness, perceived quality and fashion brand reputation. The results implies that it is necessary that fashion brands fully understand consumers' tendency and the benefits of marketing can be maximized through global positioning OOH advertising on subways which makes consumers recognize fashion brands as global ones.

The purpose of this study was to explain consumption experience of vitamin/mineral, aloe, calcium, red ginseng and glucosamine. It also explains influencing factors such as health related factors(importance of healthy eating, perceived role of food for health, health motivation), consumer attitude of healthy functional foods(reward from using healthy functional foods, confidence in functional foods) and individual characteristics(age, sex, education, income) on them. To do this, LIMDEP program was applied to estimate the logit model. The results of this study were as follows: 1) The levels of health motivation, reward and confidence from using healthy functional foods were found to be relatively low, while the levels of importance of healthy eating and the perceived role of food for health were found to be relatively high. It might imply that consumers would have some interest for health and food consumption. Also consumers expressed to have some experience for vitamin/mineral(50%), aloe(16%), calcium(23%), red ginseng(40%) and glucosamine(17%). 2) For influencing factors, age was found to be significantly influential to all of the products. If consumers were getting older, they were more likely to consume the products. In addition, reward from using healthy functional foods was found to significantly influence consumption experience of vitamin/mineral and calcium. If consumers perceived more reward from using vitamin/mineral and calcium, they were more likely to consume the products. For aloe, confidence in healthy functional foods was found to significantly influence consumption. Furthermore, sex was found to be a significant factor for consumption of vitamin/mineral.

Electric stimulators are used for various treatments, such as for pain relief and to improve rehabilitation in and out of the hospital. However, if the stimulation pulse affects the patient's heart, it can cause critical cardiac disorders such as arrhythmia or ventricular fibrillation. As a result, it must be ensured that the transmission length of the stimulation pulse does not exceed the proper range in the design of an electric stimulator. Furthermore, every anticipated risk factor must be monitored in in-vitro and in-vivo experiments. A new stimulator was designed to supply continuous 0.001 J stimulation pulses at a rate of 60 pulses per second. To evaluate the safety of the new electric stimulator and to measure its energy transfer and pulse transmission length, we built a conduction model that was filled with saline and measured the electric field at various positions in response to real stimulations. In an animal experiment with two pigs, heart disorders were induced by applying electric stimulation to tissues near the heart. These heart disorders were different from the result obtained with 9 V DC stimulation.

Several fields of science have demanded large-scale workflow support, which requires thousands of CPU cores or more. In order to support such large-scale scientific workflows, high capacity parallel systems such as supercomputers are widely used. In order to increase the utilization of these systems, most schedulers use backfilling policy: Small jobs are moved ahead to fill in holes in the schedule when large jobs do not delay. Since an estimate of the runtime is necessary for backfilling, most parallel systems use user's estimated runtime. However, it is found to be extremely inaccurate because users overestimate their jobs. Therefore, in this paper, we propose a novel system for the runtime prediction based on workload-aware clustering with the goal of improving prediction performance. The proposed method for runtime prediction of parallel applications consists of three main phases. First, a feature selection based on factor analysis is performed to identify important input features. Then, it performs a clustering analysis of history data based on self-organizing map which is followed by hierarchical clustering for finding the clustering boundaries from the weight vectors. Finally, prediction models are constructed using support vector regression with the clustered workload data. Multiple prediction models for each clustered data pattern can reduce the error rate compared with a single model for the whole data pattern. In the experiments, we use workload logs on parallel systems (i.e., iPSC, LANL-CM5, SDSC-Par95, SDSC-Par96, and CTC-SP2) to evaluate the effectiveness of our approach. Comparing with other techniques, experimental results show that the proposed method improves the accuracy up to 69.08%.

The kinetic analysis of a heavily aluminized cyclotrimethylene-trinitramine(RDX) is conducted using differential scanning calorimetry(DSC), and the Friedman isoconversional method is applied to the DSC experimental data. The pre-exponential factor and activation energy are extracted as a function of the product mass fraction. The extracted kinetic scheme does not assume multiple chemical steps to describe the complex response of energetic materials; instead, a set of multiple Arrhenius factors is constructed based on the local progress of the exothermic reaction. The resulting reaction kinetic scheme is applied to two thermal decomposition tests for validating the reactive flow response of a heavily aluminized RDX. The results support applicability of the present model to practical thermal explosion systems.
