This research started from bringing up a problem about special situation of the library and information science, which is not easy to investigate its academic characteristics, although it has settled down as a powerful science studying related phenomena as well as education required for the whole process from production of information to consumption of it. Therefore, the purpose of this research is to questingly investigate whether the personal specialty and the experience of taking courses affect recognition of the term 'library and information', and if so, through which channel it influences. In this background, data were collected from 328 students of Chonnam National University for this research, and the following are the analysis results: first, as for the personal characteristics, differences were not generated according to gender and age, but according to scholastic year the results were different; second, as for the experience of taking courses, there were not differences according to whether or not of the experience, but the results varied according to the number and type of the experience; and third, most of the respondents surveyed understood the meaning of a term 'library and information' as the conception of covering the information contained in literature and information of it, regardless of the personal characteristics and the experience of taking courses. Through these results, it can be identified that the term 'library and information' meant in the library and information science is generally understood as expansion of range, rather than chemical combination of literature and information, it is a terminology with various meanings sometimes understood differently according to the special personal experiences, and it also needs scientific investigation of it.

At military bases, environmental restoration activities resulting from oil contamination are growing concerns of preventing adverse effects on human health and environments. Its technologies are still under developing stage through some countries such as United States and Germany. This study is focused on developing model for a decision-maker to assist the restoration priority under the situation of limited resources such as budget and time. The Model, named the Base Restoration Priority Decision model(BRP model), is composed of the three factors : oil contaminants receptors, and the potential migration pathways. Each risk rating of factor is combined in the 27 matrix blocks and set immediate, moderate, and delayed action category designated restoration priority. This is categorized to group sites into three degree using the simplest of assessment system. As a result, the model will be able to apply to the effective allocation of resources for the restoration by any decision-maker because the model is easy to understand. Also, the continuous study will have established risk assessment system for the restoration of contaminated military with this study as the starting point.

Naturalized plants were identified and recorded in Busan city based on field surveys and related literature. These plants consisted of 156 taxa in total, belonging to 31 families, 95 genera, 147 species, and 9 varieties. The Compositae had the highest diversity among 31 families, with 44 taxa, followed by Gramineae, with 24 taxa, and Leguminosae, with 10 taxa Among the plants, 68.6% (107 taxa) were annuals and biennials, and 30.1% (47 taxa) were perennials. There was one shrub (Amorpha fruticosa) and one tree (Robinia pseudoacacia). Naturalized degree 5 plants, as common and abundant plant, founded 26 taxa (96.3%) were most highly ratio from Korean naturalized plants. According to the results of the analysis based on place of origin, 50 (32.1%) taxa were from Europe, and 48 (30.8%) taxa were from North America. Epecophyten was the most common of the naturalized plants, with 123 taxa Sixty-six (42.3%) taxa were introduced during period 1, and 15 (9.6%) were introduced during period 4. Ergasiophygophyten (50.6%) and Kenophyten (32.1%) were the dominant plants in these introduction periods. In conclusion, Busan city acts as a conduit for the introduction of naturalized plants. A sustainable management and monitoring strategy may be needed to prevent the introduction and naturalization of plants.

The multicultural family support project provides support services to female marriage immigrants to promote their settlement in Korea and their adaptation to marital life. This study thus investigated whether utilization of such support services is indeed related to positive changes perceived among these female marriage immigrants, and these changes, in turn, contribute to less marital conflict, marital well-being, and hope. Data were drawn from a self-administered questionnaire study in which 558 female marriage immigrants participated through the 36 centers across the nation that provided multicultural family support services based on cultural relativism and a strengths perspective. Results of structural equation modeling analyses revealed that utilization of support services, as predicted, contributed to positive changes, and such changes, in turn, were directly related to less marital conflict, higher marital well-being, and hope. As expected, marital conflict was negatively associated with marital well-being, which, in turn, promoted hope. Thus, through these paths positive changes also contributed positively to both marital well-being and hope. However, when the effects of length of residence in Korea and an ability to command Korean language were controlled for, a positive significant relationship between service utilization and marital conflict was revealed. Therefore this paper discussed the ways in which positive functions of such service utilization can be strengthened while at the same time actively addressing the dysfunctional components of such support services.

This study analyzed how North Korean defectors recognized and overcame conflict in the South Korean job culture during the course of entering and settling into South Korea, and the association between their old career and adaptation within their new careers. The study selected 13 employed participants who entered South Korea more than five years ago and experienced working. Interviews were conducted over the course of five years. The topics were analyzed after performing interviews 60 to 120 minutes long by recording and transcribing the recordings and using semi-structured questionnaires for the 13 people. The results reflected the job environment in North Korea, their career background, factors for a successful new life, their constant efforts for employment, the difficult adaption to South Korean life, pursuing job stability, accepting South Korean culture, and career compromises. The results of this study are as follows. First, they undergo difficulty in the course of selecting jobs due to the converted environment from passivity to autonomy. Second, they cannot use their previous job history and they complained about prejudice and the lack of job information. Third, major problems included their lack of adaptability, stress, and loss of economic power. The study suggests that these North Korean defectors undergo an integrated course of cultural learning. Fourth, they were hardly able to adapt. Fifth, they tried to overcome conflicts of job culture according to their personal characteristics.

The global navigation satellite system (GNSS) is using a direct sequence/spread spectrum (DS/SS) modulation. In order to recover the information data, the DS/SS system first performs a two-step synchronization process: acquisition and tracking. The acquisition process adjusts the phase difference between the received and locally generated acquisition sequences within ${\pm}T_c/2$ or less, where $T_c$ is the chip period. The tracking process performs fine synchronization. In this paper, we focus on the tracking issue. The single delta delay locked loop($\Delta$-DLL) is the optimal tracking scheme for a GNSS in the absence of multipath signals, where $\Delta$ means the spacing between the early and late correlation time offset. In the multipath environments, however, the $\Delta$-DLL suffers from huge estimation bias(denoted by $\beta$) caused by distorted correlation values. Although some modified schemes such as a $\Delta$-DLL with a narrow $\Delta$ and a double delta DLL (${\Delta}^{(2)}$-DLL) were proposed to reduce the estimation bias, they cannot remove the estimation bias completely and need more accurate acquisition process. This paper proposes a novel tracking scheme that can dramatically reduce the estimation bias, using the maximum slope change among the correlation outputs.

For successful BIM settlement, it is a key technic for engineer to design structures in the 3-dimensional digital space and to work out related design documents directly. Lately many BIM tool has been released and each supports their 3-dimensional object libraries. But it is not easy to apply those libraries to design transportation infra structures that were placed along the route(3-dimensional line). Moreover, in case of design changes, it is so difficult to reflect those changes with the integrated model that was assembled by them. Because of they were developed without consideration for redundancy of parameters between objects that were placed nearby or were related each other. In this paper, a method to develop module for modeling and placing 3-dimensional object for transportation infra structures is presented. The modules are employed by a parametric method and can deal with design changes. Also, for a railroad bridge, through developing user interface of the integrated 3-dimensional model that was assembled by those modules the applicability of them was reviewed.

Until now, the strategies for increasing community participation has been focusing on the administrative legal institutionalization, but these have not brought substantive effects. So, the need of strategies utilizing the community culture which was formed by the residents and community has been issued on recently. The purpose of this study is to explore the strategies utilizing the community culture. So, it was identified the socio-demographic variables affected the community cohesion (community social networks, community solidarity, place-attachment), that is called community spirit and culture. And through path analysis, it was analyzed the relationship among residents' socio-demographic background, community cohesion, and community participation. The findings are as follows. : the community cohesion's three elements altogether affected positively to the community participation. When regarding the residents characteristics, the strategies for increasing the participation relating to community solidarity was most relevant. the socio-demographics affecting to community solidarity are gender, age, the beneficiary, religion, job type, household income, the length of residence. the women was low at level of participation. The most important variables affecting the community cohesion are the age, the residence duration. Based on these results, the relevant strategies or approaches for increasing community participation are as follows. : using and sharing of the aged's community knowledge, making the long term living and final settlement of community residents, increasing and creating the income for the low-income residents, increasing of religious organization and its members' responsibility to community, and the purposeful extension and relevancy of women's participation. Ultimately, this study is to contribute to fomulate the residents- cultural asset driven's community welfare planning.

In this study, the factors influencing the satisfaction of the online platform musical viewing method were investigated, and the effect of the satisfaction factors on the recommendation intention and rewatching intention of the online platform viewing method for musicals was investigated. In addition, the effect of the survey subjects' degree of involvement to musicals between the satisfaction of the online platform-based musical viewing method and recommendation intention, and rewatching intention was investigated. Satisfaction factors of online platform musicals, which are independent variables, were classified into image quality, convenience, economy, and interactivity, and dependent variables were classified into recommendation intention and rewatching intention of online platform musicals, and moderator variable was set to degree of involvement to musicals, and a total of 20 hypotheses were established. An online survey was conducted on 1,454 audiences who had experience watching musicals through the online platform from August 28 to September 7, 2021, and a total of 1,418 answers were used as valid samples. As a result of the analysis, the factors that make up the satisfaction of online platform musicals appeared in the order of convenience, video quality, economics, and interactivity. It was found that the satisfaction level of watching online platform musicals had a positive effect on the intention to recommend and rewatching online platform musicals in the path of all satisfaction factors. It was found that the moderating effect of the audience's involvement in musicals between online platform musical viewing satisfaction and recommendation intention and rewatching intention had a significant effect only between image quality and recommendation intention. It shows that audiences with high involvement in musicals have intention to recommend only when they are satisfied with the video quality of online platform musicals. Particularly important point is that the convenience factor was found to have the greatest influence on the satisfaction of online platform musical viewing method, but the image quality factor was found to have the greatest influence on the recommendation intention and rewatching intention of online platform musicals.
