The public library as a public institution, funded by the public, is accountable to provide community based services. Those services can be developed through identifying community needs and implementing proper planning process to satisfy the identified needs. Under budget pressure, public libraries have changed their emphasis from the provision of the standardized services to the establishment of specialized services to reflect the differing characteristics of the community and the community members each public library serves. This paper reviews the research in this area since 1970s and suggests guidelines for the enhancement of community based public library services.

Recently, the cases that many works of the korean independent animation advance to the world by steps and some of them win the grand prix in famed global animation film festival are proving the growth potential and competitiveness. In this situation, to guarantee the continuous, and reliable as well, growth and international competitiveness of it, it is needed to ensure the government's systematic supports. Although it is a bit leaned toward the creative animation for a theater, however, or many kinds of supporting system are established and carried out, independent animation is still suffering from the financial pressure. As of now, it is must be considered of the international standing of korean independent animation and is needed to be discussed how the government's supporting systems are proceeding and what they are performing. From this point of view, this paper will study the present condition and international standing of the korean independent animation, and further, will examine and analyze the on-going supporting systems. This, consequently, intends to present the direction of government's system to promote the korean independent animation.

The purpose of this study was to observe the tissue response to the orthodontic force applied immediately after buccal horizontal subapical osteotomy of maxilla. Five mongrel cats weighing about 2.5 Kg were used for this experiment. The left upper canine and premolar of each cat served as a experimental side and the right ones as a control side. On the experimental side, a 100gm orthodontic force was applied between the upper canine and premolar immediately after the osteotomy. On the control side, the same orthodontic force was applied without the osteotomy. After 7days, the experimental animals were sacrificed. The results were as follows: 1. In the pressure zones of the experimental group, significant increase of osteoclasts and direct resolution along the alveolar bone surface was observed as compared with those of the control group. 2. In the pressure 2ones of the experimental group, a less extensive hyalinized zone was observed than those of the control group. 3. In the pressure zones of both group, no root resorption was found. 4. Tn the tension zones of the experimental group, new bone deposition increased along the alveolar bone surface as compared with those of the control group. In conclusion, the results suggest the possibility that early orthodontic treatment after orthognathic surgery may have some benefits if the stability of the repositioned segment at surgery is secured.

For Singapore, 2017 was an uneasy year. The presidential election was fraught with controversy since the revised Presidential Election Act allowed only one candidate to be eligible for the election. The bitter feud between Prime Minister Lee Hsien Loong and his siblings shocked many Singaporeans. Succession planning for the next top leadership is still veiled in obscurity. The anti-globalization trend and the increasing pressure to raise the tax have become major challenges for Singapore's economy to overcome. China's continuous diplomatic pressure has called into the question Singapore's pragmatic foreign policy. Although its relations with China were back to normal, Singapore, the ASEAN chair in 2018, is still facing intractable problems in safeguarding ASEAN centrality in the growing US-China rivalry. In the meantime, Singapore has pursued its diversity and equality, heading toward a more matured multi-racial and multi-cultural society in 2017. The first female president, Halimah Yacob, served as a symbolic epitome of Singapore's emphasis on diversity and harmony among different ethnic groups and minorities. This great milestone, however, has largely been questioned by Singaporeans, as it seemed to be a political gesture that only utilized Halimah's double minority in the level of ideologies. The election of the Malay president has led Singaporeans to think about the real equity and equality among minorities, while strongly motivated to move toward a more inclusive society. In 2018, Singaporean leaders will try to resolve many challenging problems by reaffirming leadership succession planning, which is expected to lead Singapore to pursue a more integrated society.

The purpose of this study is to derive factors that affect the acceptance of digital transformation in ports and empirically analyze the impact of these factors on the acceptance of digital transformation through a survey of port workers. Additionally, we test whether acceptance attitude plays a mediating role in the relationship between these factors and digital transformation acceptance. The variables used in this study are as follows. First, knowledge, self-efficacy, and involvement were included as variables related to individual characteristics, relative advantages, complexity, observability were included as variables related to innovation characteristics, and government regulations and competitor pressure were included as variables relate to environmental characteristics, so that a total of eight latent variables were selected. The results of this study are summarized as follows. First, two variables among individual characteristics, self-efficacy and involvement, were able to confirm a positive(+) causal relationship with the attitude of accepting digital transformation, and knowledge initially expected a positive(+) causal relationship with the attitude of accepting digital transformation, but the result was a negative(-) causal relationship, so that the hypothesis was rejected. Second, among the characteristics of innovation, complexity has a negative(-) causal relationship with the attitude of accepting digital transformation, and relative advantages and technological innovation have a positive(+) causal relationship with the attitude of accepting digital transformation. Finally, among the environmental characteristics, government regulations and competitor pressure, confirmed a positive(+) causal relationship with the attitude of accepting digital transformation. In addition, it was found that the attitude of accepting digital transformation had a positive(+) causal relationship with personal acceptance and social acceptance of digital transformation.

Background: Patients suffering with pectus carinatum complain of cosmetic problems when they stand and this in spite of wearing cloths. The standard surgical treatment of pectus carinatum is resection of the deformed cartilages, but the wide operative scar, post-operative pain and complications related with such an operation can occur. Therefore, we have peformed compressive brace therapy as a non-operative treatment for pectus carinatum and we observed the effects and the efficiency of this treatment. Material and Method: From January, 2001 to December, 2006, 109 patients wore the compressive brace for all day. The degree of satisfaction was evaluated after $6\sim9$ months of wearing the compressive brace. The degree of satisfaction was evaluated by a score of from $1\sim4$. A score of 1 was assigned when the status was worse, 2 when it was the same, 3 when there was partial improvement and 4 when remarkable improvement was observed. The degree of satisfaction was assessed subjectively by the parent if the patient was a child younger than middle school age, and the patients older than middle school age assessed the score themselves. Result: The mean score of the overall degree of satisfaction was $3.93{\pm}0.33$. Recurrence of pectus carinatum after removal of compressive brace occurred in 6 patients (5.5%) of the total 109 patients. But 4 patients of the total 6 recurred patients stopped wearing of compressive brace against our advice. The 6 recurred patients were re-corrected by re-wearing the compressive brace within 3 months after they originally removed the compressive brace. The complications were discomfort with initially wearing the compressive brace, which occurred in all patients, skin rash due to the compressive brace for 76 patients (69.7%) and skin discolorization with excessive compression for f6 patients (5.5%). The skin rash and discolorization returned to normal within a few months after removal of the compressive brace. Conclusion: This study demonstrated that non-surgical treatment with using the compressive brace for patients with pectus carinatum was effective, and especially for children and teenagers. Non-surgical treatment with using a compressive brace would be helpful for the patients suffering with pectus carinatum and who dislike surgical operations because of their fear about general anesthesia and operation-related complications. Yet long-term follow up is necessary to accurately evaluate the effectiveness of this compressive brace and the recurrences after removal of the compressive brace.
