Vehicle Scheduling Problem (VSP) is a generic name given to a whole class of problems involving the visiting of "stations" by "vehicles," where a time is associated with each activity. The studies performed to date have the common feature of a single objective while satisfying a set of restrictions and known customer supplies or demands. However, VSPs may involve relevant multiple objectives and probabilistic supplies or demands at stations, creating multicriteria stochastic VSPs. This paper proposes a heuristic algorithm based on goal programming approach to schedule the most satisfactory vehicle routes of a bicriteria VSP with probabilistic supplies at stations. The two relevant objectives are the minimization of the expected travel distance of vehicles and the minimization of the due time violation for collection service at stations by vehicles. The algorithm developed consists of three major stages. In the first stage, an artificial capacity of vehicle is determined, on the basis of decision maker's subjective estimates. The second one clusters a set of stations into subsets by applying an efficient cluster method developed. In the third one, the stations in each subset are scheduled by applying an iterative goal programming heuristic procedure to each cluster.

This study investigates Japanese-made Chinese Characters in JIS X 0212-1990(Code of the Su n.0, pplementary Japanese Graphic Character Set for Information Interchange). As a results of detailed investigation, it is found that the number of Japanese-made Chinese Characters in su n.0, pplementary set reaches to 69 characters. Among them, 29 characters are not listed even in the best known chinese character dictionary [대한화사전]. 30 characters are found in the chinese character dictionaries published in Korea, while 39 characters are not found in any of those dictionaries. The distinctive characteristic of Japanese-made Chinese characters is that those chinese characters are made in order to name the things, such as fishes, birds, trees, which do not have Chinese-made Chinese Characters.

The geodesics on the round 2-sphere $S^2$ are all simple closed curves of equal length. In 1903 Otto Zoll introduced other Riemannian surfaces with the same property. After that, his name is attached to the Riemannian manifolds whose geodesics are all simple closed curves of the same length. The question that "whether or not the set of Zoll metrics on 2-sphere $S^2$ is connected?" is still an outstanding open problem in the theory of Zoll manifolds. In the present paper, continuing the work of D. Jane for the case of the Ricci flow, we show that a naive application of some famous geometric flows does not work to answer this problem. In fact, we identify an attribute of Zoll manifolds and prove that along the geometric flows this quantity no longer reflects a Zoll metric. At the end, we will establish an alternative proof of this fact.

In this paper, I propose an efficient brand identity strategy by topic modeling the Instagram posts, one of SNS(Social Network Service) having more than 1billion world-wide and 500 million daily users. Since the 92% age groups of the Instagram is 18~50 years old (59% 18~29y and 33% 30~49), I set research analysis target three mobile commerce sites to dress and cosmetics sales sites that sale apparels cosmetics and gadgets that recently opened and have operated marketing on diverse channel including SNS. By topic modeling SNS posts for 6 months after launching the site that tagged each m-commerce site brand name or company name, I validate companies' brand identity strategy works effectively and suggest moderation of strategy for brand image. As a result, I found one of three mobile commerce site has different brand image by users and need different identity set up.

This study aims to develop a standard set for metadata to describe E-dissertation. This standard is designed for interoperability and for convenience of integrated information retrieval. This will allow one to improve existing federated searches, create united databases, and provide greater consistency for researchers searching for thesis and dissertation at different institutions. The fourteen meta elements-nine from Dublin Core and four from local need-are proposed along with newly expanded meta elements, 'thesis.degree.name', 'thesis.degree.level', 'thesis.degree.discipline' and 'thesis.degree.grantor.'

This study examines wood materials used in the inscription sword with ring pommel discovered at Geumgwanchong Tomb in Gyeongju: one set inscribed with the name "King Isaji"(K618) and another inscribed with the phrase "the Sword of King Isaji"(M336). The scabbards of both swords are made of Juglandaceae(Juglandaceae Juglans spp). Two separate wood pieces were joined together to create the hilt and the scabbard of the sword engraved with the name "King Isaji." The hilt of the sword with the inscription "the Sword of King Isaji" was also made by joining two wood pieces.

This study was conducted to propose name and role of a beauty-related specialist, a brand-new profession, recognizing that rapidly evolving culture and industries call for development of a new occupation in beauty business in the 21st century, and to suggest an approach to set up a department to produce such experts. To this end, extensive data and information were collected from relevant companies, education institutions, and all of the eighty two departments at 2-year junior colleges around the country, and were analyzed. The findings of the study are as follows: First, it was acknowledged that a new occupation distinct from existing ones is required in the beauty business. Secondly, the study has defined role of the new job; a professional beauty stylist who is competent to work across beauty, coordination and fashion with long-term perspective. Thirdly, the study suggested name of the brand-new occupation as beauty stylist. The results summarized above have meaningful implications; the study identified weaknesses of the existing beauty-related departments, and suggested practical approaches to improve them in order to provide effective education on the new profession, beauty stylist, and enhance adaptation capability.

Observation about space is looked steady in an instant, but in continuous movement, one's observation unconsciously stays at different points. In department store, customer actually observes around the store for buying, not focusing on certain point. By studying customer's movement and observation feature, buying desire and interest can be found. For analysis of the different searching-features according to the continuous-observation depending on sex, the study is set up to record movements of customers at women in Department store. The following are the findings. First, Men observed 0.2-0.4 units more in I-II section which are assumed as predominant. The result shows that men can focus on more section (around +0.4%) and longer (around +5.7%) than women do. Second, the same feature of observation depending on sex is that both men and women observe left and right section while keep focusing on middle section. Third, according to the fact that right-focused observation magnificently occurred in the image curved to right, the Space-composition has influenced on the observation of both men and women on the space. Forth, excessive number of display can cause avoidance of observation. Moreover, observation does not stay on the coverage due to wall or post, but is attracted to the brand name. As brand name causes right-focused observation in the image [(8)], brand name can be one of the reasons to attract observation in women apparel store. To sum up, this study is noticeable as it researches about continuous-observation. Furthermore, verifying the result that the composition of space and the placement of products can cause big differences in the observation feature is meaningful outcome.

Purpose: This study aims to understand effective brand naming process of an optical shop brand by a research of brand naming process of optical shop through creation of alternative. Methods: It investigated brand naming process such as character abstraction, target grasp, naming direction set, naming development and etc of an optical shop. It also looked into characteristics of alternative creation patterns such as words mix, typifier, sentence making, part words mix and etc and then, it investigated brand naming examples. Results: Creation of alternative is a phase of brand naming which has to be refined on the basis of creation of abundant alternatives and then to be developed to a brand name. This study suggested examples of brand names of optical shops which were made and adopted by creation of alternative. Conclusions: Creation of alternative in brand naming complies with concept, and it has systemic process and objective selection as an effective way in association of brand and searching words. It is necessary to have brand naming works through creation of alternative for the purpose of individual and strong brand name with desirable association and differentiation of an optical shop.
