Purpose: The purpose of this study was to evaluate the clinical and radiological outcomes of the S.E.R.I. (simple, effective, rapid, inexpensive) operation for the bunionette deformity. Materials and Methods: Between March 2005 and February 2009, 22 patients (26 feet) who had been treated for the bunionette deformity with minimally invasive osteotomy were reviewed retrospectively. Clinically, Visual Analogue Scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, shoes selectivity, disappearance of callus and patient's satisfaction level by Coughlin scoring system were evaluated. Radiologically, the bunionette was classified as four types according to the Fallat classification. The 4-5$^{th}$ intermetatarsal angle (4-5$^{th}$ IMA), the 5$^{th}$ metatarsophalangeal angle (5$^{th}$ MPA) and the length of 5th metatarsal bone (5$^{th}$ MTL) were analyzed at preoperatively and at final follow up visit. Results: VAS improved from $6.8{\pm}1.8$ points to $2.2{\pm}1.8$ points (p<0.05). AOFAS score improved from $54.0{\pm}14.2$ points to $90.0{\pm}4.8$ points (p<0.05). There was no change in shoes selectivity. 9 feet (34.6%) were satisfied with excellent results, 16 feet (61.5%) with good results and 1 foot (3.9%) with fair results. The average 4-5$^{th}$ IMA was corrected from $10.1{\pm}2.3^{\circ}$ to $4.4{\pm}1.7^{\circ}$ (p<0.05). The average 5$^{th}$ MPA was corrected from $11.5{\pm}8.6^{\circ}$ to $-0.1{\pm}4.1^{\circ}$ (p<0.05). The average 5$^{th}$ MTL was changed from $66.1{\pm}4.3$ millimeters to $64.1{\pm}4.4$ millimeters (p=0.069). There was no malunion, nonunion or delayed union and other perioperative complications. Conclusion: S.E.R.I. operation is less invasive and easy technique. This procedure is recommendable for the treatment of the bunionette deformity.

The purpose of this study is to derive differentiation strategy through strategy competition analysis on public libraries in order to enhance the competitiveness and efficiency of libraries. To that end, this study conducted a status analysis, management resources analysis, external and internal environment analysis on four public libraries located in Jung-gu, Incheon to identify the situation of strategy competition, and conducted a competitor analysis, customer segment analysis, and customer value analysis of four public libraries through various library related statistical data, national library operation evaluation data, library user satisfaction surveys, and interview with chief librarian and senior librarians. As the result, this study suggests three differentiation strategies by library. First of all, the four public libraries need to provide customized services targeting different target users within the region. Secondly, public libraries need to develop active library services that directly visit passive users, who are information have-nots, considering geographical accessibility and the composition of the population in the region. Last, public libraries should form a cultural community that cooperate with the local community and develop various programs that reflect the identity of the region.

In 1922, Hongneung forest was established to support the study of Korean forestry. Nowadays the forest also plays a role as urban forest which provides a green space for local people. This paper proposes the better management plan of Hongneung forest based on visitor monitoring. On-site surveys with a structured questionnaire were carried out from August to November in 2014 and total 750 data were analyzed. The survey results are as follows: 1) Visitors were inclusive of all age groups and most of them lived nearby Hongneung forest, 2) Visitors used the forest mainly for recreational purposes and recognized the forest as 'Green space' rather than 'experimental forest', 3) Visitors had great satisfaction from the forest visit and raised the necessity of more environment education and promotion of the program. Based on the results, the following solutions have been suggested: 1) Environment education will help visitors to raise awareness on the importance of Hongneung forest which plays a role as both experimental and urban forest, 2) Systematic visitor monitoring can contribute to efficient visitor management and administration of the areas. In conclusion, it is necessary to establish a visitor management system that enable to achieve a harmonization between nature conservation and recreational demands as well as to improve management of natural resource and service.

Dental caries in children has declined over the past few decades. However, Certain populations of children experience high levels of dental disease. To perform the highest quality dental care for the pediatric patient, the practitioner may need to use pharmacological means to obtain a quiescent, cooperative patient. Furthermore, complex treatment can impose high demands on the very young, making use of general anesthesia the preferred approach for some patients. General anesthesia is widely used to provide comprehensive dental treatment for children in USA and Europe and Scandinavia etc. Parental and patient satisfaction following completion of dental care under general anesthesia is reportedly high. Dental general anesthesia has disadvantage that it is expansive and carries a small but significant risk of mortality. However, It has the advantage of permitting treatment at a single visit, allowing immediate relief of pain and requiring little or no cooperation from the child. Rampant caries was the major indication for use of general anesthesia in the youngest age group or medically compromised patients. This study describe the characteristics of patient receiving comprehensive dental treatment under general anesthesia at the pediatric dentistry of Chonbuk National University Hospital in Jeonju, Korea in the 4year period between December 2001 and April 2005.

Impacted molars are not usual with the prevalence rate of less than 1%, however problems such as infraocclusion, extrusion of the opposite tooth and lack of space are caused. If molars are impacted, radiographic check-up and observations are needed as they play an important role in skeletal development and mastication. Causes of impaction are underdevelopment of roots, supernumerary teeth, cysts, odontomas, ankylosis and etc. In our first case, we present impacted molar which was surgically exposed and orthodontically traded. As the developmental state of the root was less than half at first visit, we observed until the root was 2/3 in its length and traction was carried out. The second case is orthodontic traded molar with compleate enucleation of the existing cysts. When trading impacted molars, direct bonding of attachments to the tooth and light continuous forces are recommended so as to ankylosis, external absorption and periodontal attachment loss avoid. Fixed appliances tract the teeth on arch and obtain eruption spaces without patient's cooperation. We report surgically exposed and orthodontically traded molars which resulted in good occlusion and patients satisfaction.

With the development and proliferation of three-dimensional(3D) printers, consumers in modern society can now print products of what they want three-dimensionally at home. However, consumers themselves would have to produce digital design maps that are compatible with 3D printers and to set up the optimum printing quality and temperature, as well as to pay for maintenance and repair of 3D printers and to respond to any possible lawsuits related to intellectual property right about designs in order to make possible consumer-tailored manufacturing through 3D printing. However, in reality, since it is very difficult for consumers to respond to these issues, it is necessary to develop services that perform 3D printing on behalf of consumers in the desired direction. Motivated by this objective, this study investigated user experiences on Shapeways(www.shapeways.com), which is a global online 3D printing product and sales companies, from many viewpoints in order to obtain insight into 3D printing services and modes which were preferred by consumers. The study result showed that quantitative evaluations on usability, search process, price adequacy, re-visit intention, diversity of design, and satisfaction of design was scored low overall. Furthermore, this study acquired insight about consumer-tailored 3D printing services through constructive suggestions on multi-language support, openness of manufacturing process, simultaneous operation of online and offline sites, design-oriented consumer-tailored manufacturing service, services that ensure delivery safety and product durability, and surface finishing services. This study is expected to provide a wide range of opinions not only on 3D printing service platform development but also on related industry and research.

This study is designed to examine the effects of information source effects of the word mouth have on the formed expectations for the private institution and to explore the formed expectations' effects on the actual sales of the educational service. Moreover, its purpose is in analyzing what medication effects the pre-conceived expectation has on selecting the educational service. After testing hypothesis, the results showed that the source effects of the information from word of mouth had a significant effect on the expectation factors, in terms of expertise, similarity, likability and familiarity expectation factors. However, it was found that effect was not significant for the truthfulness. The significant result was found on the expectation factors before visiting the private institution on selecting educational service, indicating a positive effect. As for the influence of source of the word of mouth information on selecting educational service, the results from the mediation effects of the expectation factors on selecting the educational service showed that for expectation factors, expertise had the partial mediation effect, truthfulness, perfect mediating effect, similarity, partial mediation effect, likability, perfect mediating effect, and familiarity, perfect mediating effect. A test of the mediating role of attribute expectations in the influence of WOM message source attributes on educational services choices showed the following: 1) It was proven that attribute expectations played a partial mediating role in the influence of expertise and similarity, respectively, on educational services choices. 2) On the influence of trustworthiness, likability, and familiarity on educational services choices, respectively, attribute expectations had a full mediation effect. This research differs from the previous ones, which focused only on consumer satisfaction with educational services offered by private educational institutions in that it covers not only the influences of both WOM source attributes and key component factors of educational services on both educational services choices and satisfaction with such services but also the influence of WOM source attributes on attribute expectations prior to the first visit to a particular private educational institutions, and in turn the influence of such attribute expectations on educational services choices. Most particularly, the significance of this study lies in the fact that in an effort to more clearly explain the causal relationship between WOM source effects and educational services choices a test of the mediating role of attribute expectations was conducted. Although the research seems simple, some theoretical implications can be drawn as follows: WOM message source effects on educational services choices were positive and moreover these positive impacts are likely to be reinforced by means of the mediating variable of attribute expectations.
