To compete global marketplace, many firms are adopting product families to increase variety, satisfy customer requirements, shorten lead-times and reduce costs. The key to a successful product family is the platform from which it is derived. When designing product families, it is important to resolve the tradeoff between product commonality and distinctiveness. To measure the commonality within a product family, it is necessary to develop the commonality index. It utilizes different parameters such as the number of common components, their cost, their manufacturing processes and so on. This paper present a new product family assessment index using the benchmarking method and considering environmental performance called green product family index(GPFI). Through the comparison analysis between some previous developed commonality indices and GPFI, we verify the suitability and effectiveness. Eventually, the proposed a new green product family assessment index can be helpful to design and develop the environmentally conscious product families.

This paper explains cross-national variation of CPI(corruption perception index) centering on legal culture. By critically reviewing previous researches on effects of British common law system on corruption, we define legal culture as citizens' perception of their legal system. Specifically, measuring legal culture with respect to courts fairness and courts accessibility, we test two hypotheses on effects of legal culture on corruption. A cross-national comparison of 78 countries with OLS regression analyses reveals that courts fairness tends to lower the level of corruption while courts accessibility does not have a significant effect on corruption. Based on this result, we suggest policy implications for judicial reform as well as anti-corruption measure, which puts more emphasis on reforming legal practice that hinders courts fairness than increasing legal service supply. In addition, as the essence of legal culture lies in citizens' shared perception of the legal system, we argue that a broad and solid citizens' consciousness of fair and equitable legal procedures is indispensable in preventing corruption.

This study investigates the effect of seriousness and controllability of service failure on perceived fairness, reliability, satisfaction and loyalty of customers. The result of the study is as follows. First, it was expected that a control-attribute and a seriousness-attribute would have an negative(-) impact on perceived fairness-attribute; however, the result showed that both did not have an negative impact on it. Next, a fairness-attribute of a procedure had a significant effect on trust, and a fairness-attribute of interaction and a fairness-attribute of distribution had a significant effect on trust and satisfaction. Lastly, trust had a significant effect on satisfaction while satisfaction had a significant effect on loyalty. Based of the result of this study, food-service enterprises need to perform a fast process of a recovery to overcome service failure rather than confirming a control-attribute and a seriousness-attribute of service failure. Also, they should set up a process of the recovery in the order of trust, satisfaction, and loyalty and check if this process is promptly carried out.

Plasticity of clay bodies containing bottom ashes(BA) and small portion of other wastes was investigated. Plasticity indices of clay bodies using Atterberg limits were measured. It was confirmed that the plasticity indices could be applicable in actual forming process by extrusion. The forming possible compositions were found by changing the contents of water, bottom ash, stone dust, and sewage sludge. The relationship between the plasticity and physical properties of the aggregate green body was also investigated. The compositions for extrusion forming can be expected by measured the plasticity indices and these results were confirmed by real extrusion process. There is also strong relationship between the plasticity indices and the property of aggregate green body.

This study was conducted to investigate the effects of mushroom composition (0, 4, 8, and 12%) on the quality characteristics of an extruded meat analog. The meat analog blend was isolated soy protein, wheat gluten, and corn starch (50:40:10). The extrusion condition was set to 55% feed moisture, 170℃ barrel temperature, and 150 screw speed by high moisture extrusion using a twin-screw extruder equipped with a cooling die. The integrity index, hardness, cohesiveness, springiness, chewiness, and cutting strength of the meat analog increased with the increasing mushroom content, while its water holding capacity and nitrogen solubility index (NSI) decreased. The protein digestibility decreased with the increasing mushroom content, while the DPPH radical scavenging activity significantly increased. In conclusion, the incorporation of mushrooms into the investigated meat analog enhanced its texture and antioxidant level.

This study aims to derive the conversion factor of oriental medicine based on the publicly available information to overcome the problem of the small sample size and reliability of cost analysis which spend much data gathering expense in spite of small sample. This study confirms the fairness and validity of results of analysis by using the publicly available information composed of large sample. Because of the large variation of the conversion factor depending on the types of data and methodologies, it is required to use the analysis using publicly available information in company with the cost analysis. build the health data system for cost analysis. For more reasonable conversion factor, it is urgent to construct the healthcare data system including the individual oriental medicine office.

This study attempts to redefine the concept of 'fairness' of Korean public broadcasting and tries to build a new model for evaluating the fairness of Korean public broadcasting. The author insists that the fairness in public broadcasting consists of binary components of the public and rightful reporting, and views that the public reporting represents of neutralness, balance and impartiality while the rightful reporting represents of factuality, multiplicity and the protection of social minorities. The author suggests that two criteria of the public and rightful reporting results in four models of 'shepherd', 'acrobat', 'tribune', and 'trumpeter' in accord with its focus on the public and the rightful reporting. Survey toward the professionals in public broadcasting in academia was conducted and addressed the fact that Korean public broadcasting is close to the trumpeter model with some feature of acrobat.

A computeized least-cost formulation program was applied to process emulsion-type sausages. The input data in formulation were utilized with the database which had been established in the previous study. The formulation results may provide Korean meat processors with actual examples. Meat-grade system made these examples more useful. The results of manufacturing test were as follows. The actual cohesiveness from manufactured sausages didn't correspond to the predicted values, but increased as the predicted values increased. These gabs caused by the different processing conditions between the model system and the actual processing. Hardness as well as cohesiveness could be used as the desirable index of a sausage texture. Comparing the cohesiveness and hardness of commercial frankfurters with those of test sausages, bind value constraint of $0.16{\sim}0.17$ in this test formula can be utilized for an actual formulation.

The purpose of this study is to analyze the efficiency and productivity of domestic trucking transportation companies using DEA-CCR, BCC, and Malmquist indexes. Here, we analyze the top 14 domestic trucking transportation companies, based on cargo volume. The number of freight agents, trucks, and assets are used as input variables, and cargo volumes and sales are used as output variables. The efficiency of trucking transportation companies is examined using a DEA approach, and Malmquist indexes are applied to analyze productivity. According to the DEA results, the efficiency levels of the CCR, BCC, and scales for three companies (DMU 4, 5, and 10) are 1, indicating that these companies are operated efficiently. At the same time, the Malmquist indexes show that all companies have values smaller than 1, except for the period 2012-2013, indicating that their productivity decreased. Furthermore, the TECI indexes were all larger than 1, except for the period 2012-2013, indicating that the companies are efficient. Lastly, all TCI indexes are smaller than 1, except for the period 2012-2013, indicating regressing trends.
