The purpose of this research is to study customer-supplier relationships, particularly their partnerships, to help managers and practitioners successfully design, develop, implement and deploy tools and joint practices as a means for an effective supply chain management (SCM). To achieve this purpose, a total of 1,811 potential survey questionnaire respondents responsible for purchasing, sales/marketing, quality-, and production- or operations-related functions of U.S. private manufacturing companies in SIC 35, 36, and 37 were used to collect quantitative data. Using 172 usable survey questionnaire responses, eight hypothesized relationships were tested using two independent (joint use of specific tools and joint practices) and four dependent variables (informed partners, role integrity, conflict resolution, and mutuality). From the overall perspective (customer+supplier), organizations with higher levels of joint action have higher degrees of informed partners whereas organizations with higher levels of joint action resolve conflicts formally and do not have higher degrees of mutuality.

This study probes the necessity of establishing a logistic free zone in Port of Busan. It considers the economic effects of establishing the logistic free zone of Busan Port, and suggests policy prescriptions for introducing the free zone system and improving the logistics functions of Busan Port. Using input-output table data, the regression analysis was able to provide a quantitative prediction on effects of making the Busan Port a tariff-free zone. Influence for the regional economy due to the enforcement of the free zone system this research found that a strong positive effects should be expected on the Busan regional economy once the logistic free zone would be set up at the Port of Busan. The positive economic effects on Busan regional industries might be further strengthened if the value-added logistics function of Busan Port could be supplemented by linking to the hinterland of Busan Port.

Color selection plays a vitally important role in creating impressions of individuals or companies. This is largely because colors have sensibility aspects, which relate, in part, to images and, in part, to associations. Based on theories of color harmony and sensibility ergonomics, we have developed quantitative and systematic metrics for color images. In this paper, we suggest a color coordinate system that supports color analysis and color harmony functions using color images, which can be captured by corresponding adjectival words. We focus on a prototype system for graphical logo design to exemplify our concepts. The system can be applied to a wide variety of design domains.

Phosphorylation upon protein is well known to a key regulator that implicates in modulating many cellular processes like growth, migration, and differentiation. Up to date, grafting of multidimensional separation techniques onto advanced mass spectrometry (MS) has emerged as a promising tool for figuring out the biological functions of phosphorylation in a cell. However, advanced MS-based phosphoproteomics is still challenging, due to its intrinsic issues, i.e., low stoichiometry, less susceptibility in positive ion mode, and low abundance in biological sample. To overcome these bottlenecks, diverse techniques (e.g., SCX, HILIC, ERLIC, IMAC, TiO₂, etc.) are continuously developed for on-/off-line enrichment of phosphorylated protein (or peptide) from biological samples, thereby helping qualitative/quantitative determination of phosphorylated protein and its phosphorylated sites. In this review, we introduce to the overall views of enrichment tools that are universally used to selectively isolate targeted phosphorylated protein (or peptide) from ordinary ones before MS-based phospoproteomic analysis.

Objectives: This study aimed to provide basic information for the trend of individual-authorization on functional food materials in Korea to side of Korean medicine. Methods: Approval of materials for individual-authorized functional food in Korea was analyzed from 2004 to August 2015 using database from Ministry of Food and Drug Safety (MFDS), regarding the kinds of function, materials and their functional level by year. Results: Korean functional food market has rapidly grown to 1.56 trillion Won in 2014, with about 10% of annual growth rate. In particular, the increase of individual-authorized functional food is worth of notices, in detail 313 kinds of functional materials covering 31 body functions have been approved by August 2015. 15.7% of individual-authorized functional foods have used the herbal materials. This quantitative and qualitative expansion of functional foods, especially of individual-authorized functional foods, will affect the herbal drug industry negatively. Conclusion: This study figured out the current pattern of material approval for individual-authorized functional food in Korea, which would be essential in development of strategies by Korean medicine community in order to overcome such conditions.

The functions of stocking and releasing in logistics center consist of three major procedure such as receiving, shipping and stock managements. Each process includes various sub-processes which are complicatedly connected with each other. Furthermore, lots of operators execute various tasks in the different sub-processes, simultaneously. It makes difficult to standardize, monitor, and analyze the processes. This paper proposed the quantitative methodology using process mining approach to discover and analyze receiving and shipping processes. For this purpose, the PDA operation log data is analyzed to build a realistic process model. The deduced model has been compared with official process model. In addition, task assignment and social networks analysises are carried out by utilizing process mining tools. Also, it has been proposed how to improve the processes with the analytical simulation model based on the results of process mining.

We are faced with water pollutions on a population explosion. Considering the importance, we research European rivers based on OECD reports. Observations in the reports have defects that make evaluation of environmental situations be difficult. By using interpolations in the compensation quantitative structure-activity relation ships (CQSAR), we complement the defects in the water quality of rivers through big cities. Thus, we get complete data set for dissolved oxygen, biochemical oxygen demand, and total phosphorus. Using the data set, we examine re-naturalization of the Rhein and the Donau in Germany. We investigate the effect of dams between Slovakia and Hungary, by using reconstructions of neural networks in CQSAR. The reconstructions have functions to extract a principal relation. On the investigation, we examine assertions of conservation groups. As the result, we confirm the re-naturalization is effective, and find a negative effect of the dam construction on changes of dissolved oxygens in the Hungary Donau. We investigate the Seine and the Thames, too.

The optical performances of rounded prism films were investigated using a ray tracing technique. The angular distribution of the luminous intensity was obtained as functions of the prism pitch and the curvature of rounded apex and valley of prism arrays. The gain of the on-axis luminance decreased with decreasing curvature (increasing diameter) and pitch. The existence of the curved area on the prism film decreased the recycling efficiency of the prism film, i.e., the rays which would otherwise have been recycled through total internal reflections via the prism surfaces were refracted on the curved regions and redirected toward directions other than the on-axis direction. Quantitative correlation between the luminance gain and the curvature in addition to the prism pitch was obtained, which might serve as basic data for the optimization of prism films and the manufacturing processes.
