This study analyzes the problems in reading program of public libraries and provides some suggestions for the program development and management. For this analysis, I sampled and examined 350 news articles to reading programs done in the public libraries between 2013 and 2015. The result shows that 41.4% of the collected articles were the news about the reading programs in Seoul Metropolitan areas. While the articles about simple reading programs occupied 69.9%, the mixed activity programs reached a significant amount in total. In addition, 51.3% of program participants was under the elementary children and their parents, but only 9.0% program participants came from low socioeconomic status classes. 86 reading programs (28.4%) were designed for one-day events without a long-term policy. Based on such analyses, this study provides three suggestions: utilizing public relation teams and communicating mass media to advertize reading programs to local residents, developing systematic reading programs in users' needs, managing the reading programs for all kinds of local residents.

The institutional repository and linked data share a purpose, co-creation and joint usage of information resources. Therefore, a new approach linking these two concepts can be utilized for co-production and utilization of resources. This study hoped to configure the Korean dCollection repository as linked data. For this purpose, first, we analyzed the current data structure of dColleciton. Second, we investigated the resource types which dCollection is targeting. Third, we focused and analyzed a case study of resource types targeted by dCollection constructed as linked data. Fourth, this study examined in detail how to build the linked dCollection data and how to connect this linked data to the linked cloud. Finally, we discussed the problems that might oc cur in the process of building the linked data.

Based on the analysis of historical backgrounds and terms of Taekwondo, this study was conducted to analyze the characteristics of cataloging records related to Taekwondo in 53 national libraries of each country. The results are as follows. To begin with, while most of the Taekwondo-related records are concentrated in some specific national libraries such as the United States, Germany, Republic of China, United Kingdom, and Spain, there are four libraries that do not have one. Second, the title keyword of Taekwondo-related records was 93.5% for the term that directly meant Taekwondo and 6.5% for Korean martial art, Korean art of self-defense, and Korean karate etc. The frequency of materials by language is 38.7% for English and 8~9% for German, Spanish, Chinese, and Korean, respectively. The Roman translation for Taekwondo is 50.3% for 'Taekwondo', and 18.5% for 'Tae kwon do'. Third, the subject heading of Taekwondo-related records was 86.9% for 'Tae kwon do' or 'Taekwondo' etc. 7.6% for 'karate', 5.7% for general subject heading, and 12.0% for blank. This means that some national libraries misunderstand Taekwondo as karate.

In this paper, the characteristics of the inductor and capacitor, which are the basic components of the circuit, are constructed in a form that can be used in the LTCC multilayer. The inductors and capacitors used for the analysis were designed with rectangular spiral structures and MIM structures inside dielectrics with a dielectric constant of 7, respectively. The measured results were extracted from each element of the equivalent circuit proposed by the curve fitting method and verified the validity of the proposed equivalent circuit based on the extracted results. The analyzed inductor and capacitor were implemented in the form of library and proved its usefulness by applying to Elliptical type 5th LPF design. The LPF was measured through practical production, and as a result, the insertion loss in the passband DC ~ 3.7 GHz was up to 1.0 dB, the return loss was 19.2 dB, and the attenuation in the rejection band was 23.9 dB, which was close to the design goal.

This study is a primary research aimed at the information service of public libraries for aged persons who are increasing in our society. In the year 2000, the total population of the world is expected to be up to sixty one hundred millions and the aged population over the age of 65 is also expected to be about 14.3 percent. The population of Korea will be twenty third(23) in its number throughout the world and the population of aged persons is expected to increase to 7 percent according to the United Nation. The service of public libraries should enhance the quality of each individual life and contribute to communities in the conviction of service. The social welfare of aged person is, in a way, to transfer the responsibilities of taking care of aged persons from the family to society. When we plan, consider and offer the equal rights and o n.0, pportunities for them to access to public libraries, then the service of public libraries will be a momentum for the reformation of our society. The public libraries should develop a section for the aged persons as a non-profit organization and further should provide some communication skills, specific a n.0, pparatus for poor eye sight, and some financial su n.0, pport for them.

A novel esterase gene, est01, was successfully unearthed from a biogas digester microbiota metagenomic library. The 1,194 bp est01 gene encodes a protein of 44,804 Da (designated Est01). The amino acid sequence of Est01 shows only moderate (33%) identity to a lipase/esterase. Phylogenetic analysis and biochemical characterization confirmed that Est01 is a new member of family VIII esterases. The purified Est01 from recombinant Escherichia coli BL21 (DE3) showed high hydrolytic activity against short-chain fatty acid esters, suggesting that it is a typical carboxylesterase rather than a lipase. Furthermore, the Est01 was even active at $10^{\circ}C$ (43% activity remained), with the optimal temperature at $20^{\circ}C$, and had a broad pH range from 5.0 to 10.0, with the optimal pH of 8.0. These properties suggest that Est01 is a cold-adaptive esterase and could have good potential for low-temperature hydrolysis application.

The purpose of this research is to expand much more the facilities and collections of public libraries in Korea for performance of its function, for the life-long education institution. In order to accomplish the purpose of this study, I looked in to the present conditions of the facilities, collections, service facilities in public libraries and suggested a tentative plan on the basis of every kinds of statistics. The result of this thesis can be summarized as follows : 1. Now, 227, 110 populations of the effective service per library are so many that 181 public libraries in Korea have largely deficient state. To solve, a n.0, pplied for Armstrong's standards (5, 000 populations of the effective service per library, and the number of an elementary school 5, 412 elementary schools in Korea). In the former case should be establish 8, 221 public libraries, in the latter case should be established at least 5, 412 public libraries. 2. The public library in Korea is possessed of building areas of 82, 267 pyong (468 pyong per library). They are very poor state comparing with population. Therefore, the building area should be expand according to population by region. Also, the reading facilities of 88, 455 seats, 465 population of the effective service per seat, are largely insufficient of situation. And consequently they should be secured at least 205, 535 seats with standards of five seats per 1, 000 population. 3. The public libraries in Korea keep collection of 4, 517, 280 volumes. As there are 11 volumes per 100 persons, they are very deficient state in figures. Therefore, in this study, suggested Schenk's standard (1 volume per a person) and IFLA standard (2 volumes per a person). Under the circumstances of our country, however, they should be secure at least 41, 106, 993 volumes with a Schenk's standard of one volume per a person. To meet this kind of necessary conditions, there must not only be a national policy but also be a facility for every residents to utilize for educational place, and to every librarians of public libraries, they have to do their best to open their library to every citizens, when needed, with their self-conceit. Cooperating with policy-makers, users, and librarians, making every endeavors to develope Korean libraries, we can promise the hope that our public library will be progressed towards future.

The morphological characteristics of the bloom-forming dinoflagellate Akashiwo sanguinea isolated from Jangmok Harbour, Geoje in Korea was examined using light and scanning electron microscope (SEM), and its large subunit (LSU) rDNA was sequenced. Additionally, investigation was done on the effects of temperature and salinity on the growth of A. sanguinea. The cells were dorso-ventrally compressed up to 54.7-70.3 ㎛ long and 31.5-48.5 ㎛ wide. The epicone was conical while the hypocone was separated into two lobes. The nucleus was positioned at the center of the cell. The yellow-brown chloroplasts radiated close to the cell center. SEM observation indicated that A. sanguinea has an e-shaped apical groove. Molecular phylogeny based on LSU rDNA gene sequences revealed that the A. sanguinea strains isolated from Jangmok Harbor were classified in the clade of ribotype A. The maximum growth rate (0.50 day^-1) was observed at 20℃ and 20 psu, while the maximum cell density (1,372 cells mL^-1) was observed at 25℃ and 30 psu. This indicates that the blooms of A. sanguinea ribotype A in Korean coastal area are affected by water temperature, rather than the salinity.
