To promote libraries as "Libraries for All," it is essential to assess the current state of regional library infrastructures and explore policy support strategies for their improvement. This study develops the 'Library Vitality Index' as a metric to evaluate libraries' capabilities as sustainable infrastructures. The index assesses various aspects, including libraries' environmental responsiveness, accessible design, level of digital transformation, and capacity to provide universal cultural services. The research involved a comprehensive review of domestic and international cases, Delphi surveys, and expert group interviews to derive the final set of indicators. These indicators were weighted based on their importance using AHP analysis. The final index consists of three components: regional library activation (300 points), individual library capacity (470 points), and feedback systems (30 points), with a total of 800 points. The index includes 108 items, divided into 14 for regional library activation, 88 for individual library capacity, and 6 for feedback systems.

The purpose of study was to introduce menus consisting of traditional local foods consumed in Busan, Korea. Five different types of formal meal menus with three side dishes and five different types of informal meal menus of which the main dish was not cooked rice were developed. Scores for the menu evaluations of formal and informal meals were higher than 7.9 (mean score of 6 category) on a 9.0 scale, suggesting that the menus were well constituted in terms of 'repeated use of ingredients and cooking methods', 'balance between main and side dishes', 'frequency of usage of local products', 'nutritional balance', 'variety of dishes', and 'popularization'. Nutritional values of menus were compared with those of the KDRI for men aged 30~49 years old. All ten menus reflected a low calorie, high protein, and high fiber diet. Mineral contents (Ca, Fe, Zn, K, and Na) of the above 10 menus were higher than those of the KDRI. On the other hand, vitamin contents slightly differed according to meal type due to limited fresh vegetable usage in the winter season. Vitamin A, B ($B_1$, $B_2$, niacin, $B_6$), C, folic acid, and E contents in the five informal menus were found to be proper or greater than those of the KDRI. However, for the formal meal menus, all vitamin contents except that of vitamin A in menu type I was lower than that of the KDRI. Content of vitamin C in menu type V was approximately 50% of that of the KDRI. The most preferred formal menu was consisted of Ogokbap, Boreumjijimi, Dongchimi, Namul (nine varieties), Gaksaeksanjeok (Shark/Daegu/Gunso), and Gimgui. And that for informal menu was consisted of Honghapjuk, Baechu kimchi, Dongchimi, Miyeokseolchi, Kodari jorim, and Neulgeun hobakjeon. Suggestions for providing more fresh vegetables or fruits for certain types of meals (formal meal type V) were offered. Additionally, pre-preparation of sea products were required to reduce Na contents.

Geochemical characteristics, water quality, $NO_3{^-}$ contamination and the origin of $NO_3{^-}$ were analyzed for the groundwater located at Ogcheon, Korea. The water qualities were weakly acidic to weakly alkalic and redox potentials indicated reduction condition. Compared to granitic rocks, metamorphic sedimentary rocks with intercalations of limestones and dolomites tended to be more effectively dissolved, resulting in higher pH and higher concentrations of dissolved ingredients. Contamination of heavy metals was not revealed. Geochemical reactions of carbonate rocks and influxes of artificial contamination ingredients seemed to simultaneously determine the geochemical characteristics and water qualities in the study area. From the results of ${\delta}^{15}N$ isotope analysis, the origin of $NO_3{^-}$ was estimated to be influenced dominantly by agricultural activities and human feces and urine.

This is a study on village names in a plain region of Changnyeong-Gun, a mountain region of Bonghwa-Gun and an island region of Namhae-Gun. The three regions differ in geographical features. The data are based on 455 village names in Changnyeong-Gun, 552 village names in Bonghwa-Gun and 275 village names in Namhae-Gun found in the 1 : 50,000 topographic map. The method of this study is to analyze the word structures of village names in the five basic concepts in geography : Man-Land(Natural Environment and Human Activities). Spatial Relation, Distribution, Region and Transition. The main results of this study are as follows: 1. Naming of villages are related to Natural Environment(41%), Human Activities(23%), Region(17%), Spatial Relation(13%), Distribution(5%), and Transition(3%). Of these six factors, Changnyeong-Gun is relatively dominant in village names related to Spatial Relations, Region and Transition ; Bonghwa-Gun Natural Environment and Namhae-Gun Human Activities and Spatial Relations. But the three Guns are absolutely dominant in village names related to Natural Environment and Human Activities. 2. A village name is divided into the specific name part(given name) and the generic name part(classified name). Names related to Human Activities, Spatial Relations, Distribution and Transition are more frequently found in the specific name part. Therefore, they are used as the given name of a village name. Whereas names related to Natural Environment and Region are more frequently found in generic name part, which means that they are used as the classified name of a village. 3. The word structure of a village name usually has two parts a frontal part(given name) and a rear part(classified name). The two parts have a particular pattern in the geographic concept when they are combined. 1) In the village names related to in their frontal part of the word structure, is more frequently combined as their rear part in Bonghwa-Gun, in Namhae-Gun and in Changnyeong-Gun. 2) In the village names related to in their frontal part of the word structure, is more frequently combined as their rear part in Changnyeong-Gun, in Namhae-Gun and in Bonghwa-Gun. Accordingly, Man(Human Activities) - Land (Natural Environment) can be considered the most important concept in the naming of villages, because the concept is most frequently used in the word structures of village names.

Pastry overlay network is one of structured P2Ps using DHT(Distributed Hash Table). To reduce the number of messages among nodes, Rosary and LAR have been proposed by exploiting spatial locality and caching, respectively, in the Pastry. Rosary consists of Inter-Pastry and Intra-Pastry. A root node is assigned as a representative in each Intra-Pastry and it has the responsibility of Inter-Pastry and Intra-Pastry routing. Therefore, Rosary has several disadvantages; 1) low fault tolerance in case of root node failure 2) routing hop count increases because of the use of root nodes compared to the existing structured P2Ps, and 3) the communication load is concentrated in some specific areas. LAR has inefficient problems in that caching is not distributed among nodes in Intra-Pastry and caching is used by only nodes in the Intra-Pastry. In this paper, we propose an improved Pastry called Doughnut to overcome the above problems of Rosary and LAR. By dividing nodes with the local characteristics, the Doughnut consists of Inter-Pastry and Intra-Pastry, and all nodes have the responsibility of Inter-Pastry and Intra-Pastry routing. This results in that all nodes perform the role of the existing root node. This solves the problems of the reducing of fault-tolerance, the increasing of routing hop count, and the not-distributed communication load. Also Doughnut can use cache effectively because it guarantees the even cache distribution in local(Intra-Pastry) and the cache contents in local can be used in the other local. The proposed algorithm is implemented using simulator and the experimental results show the effectiveness of the proposed method compared to the existing method.

This study reviews recent changes in parenting support policy in Japan, and examines the roles and functions of day-nursery as the base for parenting support in the local community. The purpose of this study is to provide implications for the direction of the parenting support policy and child-care facilities for the local communities in South Korea. The analysis concentrates on the official national reports such as the Declining Birthrate White Paper and Japan's National Guidelines for Care and Education at Day Nursery by the Japanese Cabinet Office. The study finds that the Japanese government has introduced comprehensive medium and long-term policies for all the members of the community with recognizing the changes in the domestic and foreign child-rearing environments and social needs. These policies have also helped to improve the social awareness of parenting. The role of the day-care center has been raised as a significant part of the support for child-rearing in the local community due to the revision of the Child Welfare Act for nursery school teachers in 2001 and the official announcement of Japan's National Guidelines for Care and Education at Day Nursery in 2008. The study also concludes that the social responsibility of the nursery center has been strengthened by being utilized as a public resource for the community. From the findings, we can elicit the conclusions and implications that the roles and functions of child care centers as a significant base for parenting support in the local communities need to be considered. We also listen to the voices of stakeholders such as parents and staff of child care centers. Last but not least, we would understand the social role and importance of bringing up children by cooperation of the community members, and promote the role of child care centers as a central place providing and communicating information on child-rearing in the local communities.

Rural tourism is considered one of the main components of travel today. This may explain the emerging interest in tourist behavior at rural sites. Nevertheless, it can be argued that research on tourists' motivation as well as segmentation for visiting rural sites is still in its infancy. The purpose of this study has three main objectives: (1)to adjust the motivations of rural tourism to the general motivations for all travelers and find the core factors for rural tourists. (2)to show the segmentation of korean rural tourists, and (3)to suggest the characteristics of rural tourists' typology. This paper was conducted through two studies: a literature review and a survey for empirical exploration of the ideas. The empirical data are extracted through convenience, and the valid questionnaires totaled to 828. The Frequency, Descriptive, Factor, Cluster, Discriminant, Cross-tabulation analysis were used for the data analysis. The results of analysis indicate that the rural tourists' motivation is consisted of 14 factors. the key elements play a major role in rural tourism. and the rural tourists' market was divided into 5 different groups. The results of this study will not only contributes to a better understanding of rural tourism due to clarification of tourist motivations but also have implication for the development and management of rural sites.
