Purpose: This study focuses on the Chinese smartphone market to estimate product attributes influencing Chinese customers' preference for developing new smartphones through conjoint analysis. Research design, data and methodology: The online questionnaire survey is processed among Chinese potential smartphone customers. Conjoint analysis including traditional conjoint analysis (TCA) and choice-based conjoint analysis (CBCA), is used to analyze the useful data of 500. Results: Results indicate that price is the most important predictor while screen size is the least for Chinese customers' preference whether the method is TCA or CBCA. However, the importance of brand, capacity, CPU, and screen design is different. Moreover, based on each smartphone attribute level's utility, the new products with the best combinations are different compared with both methods. Finally, the predicted market shares of the top 3 products are the same with maximum utility rule model between TCA and CBCA. However, when considering with the new best combined product, they are significantly different. Conclusions: Managers should recognize the differences between TCA and CBCA and select the best method to develop new smartphones for sustainable business in the Chinese competitive market based on the important attributes of price, brand, capacity, CPU, screen design, and size.

This study addresses how the main group of community ritual changed as the regional community changed during the period of Japan's colonial rule of Korea with emphasis on Gwanseongmyo in Jangchung-dong, Seoul. First, almost every regional community was changed because of city planning which was carried out by Japan in Korea for colonial exploitation and for the use of military bases. Mapo-dong and Seobinggo-dong were the appropriate examples. The city planning projects by the Japanese colonial government selected Jangchung-dong as the place of settlement of many Japanese people. The stream, Cheonggyecheon, made a border between the Korean and Japanese settlements and the traditional system of regional community in Jangchung-dong was changed and reorganized considerably. Second, the Japanese government used the rituals of regional community purposefully to combine them with the ceremony in the Japanese shrine. Those who supported Japan performed the regional rituals and tried to follow the policy of 'Rule of Culture' required by the Japanese colonial government. However, most regional rituals continued as they were before Japan's colonial rule of Korea without any change. Under this new trend the ritual of Gwanseongmyo was changed from the ritual for worshipping Guan Yu to that of the regional community. Last, the main groups that led the rituals of regional community were diversified during the period of Japan's colonial rule of Korea. In other words, the rituals of community used to be led by the families that lived in the region for generations before Japan's colonial rule of Korea. However, they were later led by various groups that emerged as a result of the colonial rule, urbanization, commercial development, regional differentiation, and so on. As an example,Yeongsinsa of Gwanseongmyo,which was the main group to lead the ritual of Gwanseongmyo, shows that the regional community rituals were extended to worshipping Guan Yu. The members of the main group to lead the ritual were pro-Japanese senior officials who were formerly military officers. This shows that the main groups leading the regional community rituals were further diversified.

The outbound containers in a container terminal are classified into a few groups by their weights and stacked separately in a yard for easy and efficient handling. In order to maintain the balance of a ship during loading, containers of heavier weight groups should be fetched out of a yard and loaded onto the ship before those of lighter weight groups. However, the weight information used to determine the weight group is usually imprecise. Therefore stacks will actually be filled with mixture of different weight groups and rehandlings are unavoidable during loading operation. This paper presents a method for estimating the number of rehandlings caused by imprecise information and a scheme for generating a simple but efficient slot assignment rule. Experiments have shown that a rule generated by the proposed method can reduce the number of rehandlings by about $20\%$ compared to the traditional slot assignment method which stacks only the containers of the same weight group in a single stack.

Association rule mining techniques enable us to acquire knowledge concerning sales patterns among individual items from voluminous transactional data. Certainly, one of the major purposes of association rule mining is utilizing the acquired knowledge to provide marketing strategies such as catalogue design, cross-selling and shop allocation. However, this requires too much time and high cost to only extract the actionable and profitable knowledge from tremendous numbers of discovered patterns. In currently available literature, a number of interest measures have been devised to accelerate and systematize the process of pattern evaluation. Unfortunately, most of such measures, including support and confidence, are prone to yielding impractical results because they are calculated only from the sales frequencies of items. For instance, traditional measures cannot differentiate between the purchases in a small basket and those in a large shopping cart. Therefore, some adjustment should be made to the size of market baskets because there is a strong possibility that mutually irrelevant items could appear together in a large shopping cart. Contrary to the previous approaches, we attempted to consider market basket's size in calculating interest measures. Because the devised measure assigns different weights to individual purchases according to their basket sizes, we expect that the measure can minimize distortion of results caused by accidental patterns. Additionally, we performed intensive computer simulations under various environments, and we performed real case analyses to analyze the correctness and consistency of the devised measure.

The Incoterms which is one of the most useful international instrument for sale of goods provides when a contract goods deliver, risk passes and how costs are allocated between seller and buyer on the contract as long as they agree to use a rule of the Incoterms rules. The Incoterms rules have come into effective to use for an international or domestic trade of goods since January 2011, which have been modified several times since these established by ICC in 1936. The origin of Incoterms rules may had been appeared from English traditional FOB terms that had been affected to American regulations for the sale of goods. The Incoterms rules which had been started from the traditional English FOB terms and American FOB terms have been expanded other trade terms, such as CIF. Although FOB is based on the COD(Cash on Delivery), it is possible replaced COD to CAD(Cash against Delivery) through the use of Bill of Lading and Letter of Credit in the international sale of goods between seller and buyer according to the development of infrastructures on the international commercial transactions. This article exercises the process of transition of the Incoterms rules, being based on the English and American traditional FOB contract form through review literatures, judical precedents and provisions. Then this article provides some feasible alternatives to attempting to resolve some regulation problems of FCA, CPT, CIP, and D-rules in the Incoterms$^{(R)}$ 2010.

Models for human cognition currently discussed in cognitive science cannot be appropriate ones. The symbolic model of the traditional artificial intelligence works for reasoning and problem-solving tasks, but doesn't fit for pattern recognition such as letter/sound cognition. Connectionism shows the contrary phenomena to those of the traditional artificial intelligence. Connectionist systems has been shown to be very strong in the tasks of pattern recognition but weak in most of logical tasks. Brooks' situated action theory denies the. notion of representation which is presupposed in both the traditional artificial intelligence and connectionism and suggests a subsumption model which is based on perceptions coming from real world. However, situated action theory hasn't also been well applied to human cognition so far. In emphasizing those characteristics of models I refer those models 'left-brain model', 'right-brain model', and 'robot model' respectively. After I examine those models in terms of substantial items of cognitions- mental state, mental procedure, basic element of cognition, rule of cognition, appropriate level of analysis, architecture of cognition, I draw three arguments of embodiment. I suggest a way of unifying those existing models by examining their theoretical compatability which is found in those arguments.

Jedoguk and Jaesiljaesanjeongriguk were the offices related to the reorganization of the royal finance during the Residency-General period and surveyed royal facilities. Jedoguk surveyed palaces, offices and royal ritual facilities in the manner of traditional survey. However, Jaesiljaesajeongriguk which is the successor office to Jedoguk surveyed royal facilities using the modern surveying techniques and figured out the value of royal facilities. In 1908, most of the royal facilities were nationalized and were managed as government property by Takjibu. These nationalized royal facilities were used new modern facilities under the rule of Japanese.

Traditional business process management systems provide verification tools of process models to deploy and automate the models. However, there are not so many studies on how to maintain systematically collaborative process models such as supply chain processes when companies are willing to change and update the collaborative process models. In this paper, we analyze change patterns of collaborative processes and declare 19 change patterns. In addition, we apply the change patterns to the process interoperability patterns in order to identify the change problems in case of independent process changes of collaborative processes. As a result, we devise an independency checking algorithm of process changes in collaborative processes.

It is now well recognized that the ultimate limit state approach is a much better basis for design and strength assessment of ships and offshore structures since it is difficult to determine the realistic margin of safety using the traditional allowable working stress approach on the basis of linear elastic method solutions together with buckling strengthchecks adjusted by a simple plasticity correction. This paper outlines ALPS theory for ultimate limit state assessment of ship structures. ALPS is a computer software which stands for nonlinear Analysis of Large Plated Structures. Application examples of ALPS program to ultimate limit state assessment of plates, stiffened panels and ship hull girders are presented. A benchmark study is made by a comparison with the ALPS solutions with other methods including class rule formulae, nonlinear finite element methods and experimental results. Future trends on ultimate limit state assessment of ship structures are addresse[1]
