This study evaluated the relative efficiency of mobile emission reduction countermeasures through a Data Envelopment Analysis (DEA) approach and determined the priority of countermeasures based on the efficiency. Ten countermeasures currently applied for reducing greenhouse gases and air pollution materials were selected to make a scenario for evaluation. The reduction volumes of four air pollution materials(CO, HC, NOX, PM) and three greenhouse gases($CO_2$, $CH_4$, $N_2O$) for the year 2027, which is the last target year, were calculated by utilizing both a travel demand forecasting model and variable composite emission factors with respect to future travel patterns. To estimate the relative effectiveness of reduction countermeasures, this study performed a super-efficiency analysis among the Data Envelopment Analysis models. It was found that expanding the participation in self car-free day program was the most superior reduction measurement with 1.879 efficiency points, followed by expansion of exclusive bus lanes and promotion of CNG hybrid bus diffusion. The results of this study do not represent the absolute data for prioritizing reduction countermeasures for mobile greenhouse gases and air pollution materials. However, in terms of presenting the direction for establishing reduction countermeasures, this study may contribute to policy selection for mobile emission reduction measures and the establishment of systematic mid- and long-term reduction measures.

This study was conducted from 2003 to 2005 at crop field of National Institute of Subtropical Agriculture, RDA, in Jeju. The treatment consisted of chemical fertilizer 100%(CF 100%, T1), cattle manure 100%(CM 100%, T2), CF 50%+CM 50%(T3), CF 25%+CM 75%(T4), CM 100%(1st yr.)+CF 100%(2nd yr,)+CM(3rd yr)(T5), CM 100%(1st yr.)+CF 100%(2nd yr.)+CF(3rd yr.)(T6). The highest substitution effect of chemical fertilizer for cattle manure indicated that the highest yield(Avg. 11,169 kg/ha) obtained from CM 100%(1 yr.)+CF 100%(2 yr.) treatment. The forage yield of CM 100%(1 yr.)+CF 100%(2 yr.) was 4% more than CM 100% application whereas was 3% less than CF 100% application. Changes of physical and chemical properties of soils for applications of CF 100% and CM 100% was clearly in cattle manure application. Especially, cattle manure application in pasture were superior to chemical fertilizer application with respect to organic matter(OM, %), total nitrogen(T-N, %), and avaliable phosphorous($P_2O_5$, %) contents of soils. In this present study, cattle manure application recorded slightly lower forage yields than CF 100% application but the combined use of cattle manure and chemical fertilizer was attribute to reduction of chemical fertilizer application rate as well as maintaining soil health on long-term basis.

This research pertains to the interpretation of the many characteristics of the growing process of Library and Information Science in Korea with respect to its connection with discussion of the system of discipline. The result of the research are as follows. The Library and Information Science in Korea has gone through three distinct stages. The first stage spans the period from the late 50s to the 1960s during which three was an attempt to establish a relatively independent system of scholarship of Library and Information Science, although it was still heavily reliant on scholarship from Japan and the United States. The main characteristics of this first period is, firstly, that there a n.0, ppeared, for the first time, an awareness of a need to escape the attitude of foreign-orientation and to develop our own scholarship. Secondly, an effort was made to constitute the scholarship as a science (social science). Thirdly, there began a faint effort to import and a n.0, pply Information Science. The second stage covers the period between the 70s and the 80s, and saw the induction of Information Science begin in earnest and become the subject of education and research. The period was also marked by exploration of an alternative term to "Library Science", which was at the time being used. In addition, the period was a time of confusion for the examination of scholarship due to the induction of the new field of Information Science to what had already been a fragile structure of scholarship. This phenomenon served to intensify the doubts which had surfaced about existing term of Library Science, and ultimately played a large role in the a n.0, ppearance of the new term of Library and Information Science. Of course, there were a number of reasons which had made the change of term difficult, but it and be seen that the term change began in earnest after the change was adopted in the names of the university departments associated with the field in the late 80s. The third stage covers the period after the begining of the 90s. This stage saw the prominence of criticism and self-examination of the existing distorted foundational structure of Library and Information Sciences in Korea at the time, and, at the same time, a new methodology or research paradigms were advocated. It was a presenation of a new way of achieving a "Korean Library and Information Science" in order to understand and overcome not only the problems within the Korean libraries, but also within Library and Information Science in Korea. This caused repercussions to be felt not only among academics, but also among those actually working within the library systems. It moved academics toward a more practical scholarship, it inspired the prominence of a new scholarly methodology called a reform in academic writing, and even influenced specific research activities.research activities.

This study aims firstly to examine whether adolescents' life satisfaction influences their fandom activities, then to analyze whether the influences of ego resiliency and peer relations on fandom activities vary by adolescents' life satisfaction and how, if they do, and finally, using multi-group analysis, to identify whether there are gender differences in their fandom activities. The results are as follows: Firstly, as adolescents' life satisfaction is lower, their involvement into fandom activities are increased. Secondly, peer relations and ego resiliency has different relations to fandom activities, that is the former have indirect impact on fandom activities. Ego resiliency has both direct and indirect influence on fandom activities, that is adolescents who have higher ego resiliency participate more actively into fandom activities and this influence is mediated by life satisfaction. Finally, the degree of participation into fandom activities depends of adolescents' gender, that is girls involve in fandom activities more actively. One consistent finding of this study is that fandom activities are negatively related to life satisfaction. The results of this study show that more various programs to enhance life satisfaction, self respect and peer relations of adolescents are necessary to facilitate healthier culture of adolescents.

The current society characterized by knowledge-based information technology and multiculturalism put more emphasis on problem-solving skills, creative thinking, and communication skills than any other periods did. In response to the demand of the current times, multidisciplinary, or convergence courses and majors are being created and conducted in college education, yet, with the lack of specific teaching and learning model for the convergence courses. In this context, this study aimed to examine PBL as an instructional model for the convergent approaches in classroom, since PBL has been regarded as a model for fostering the 21st century learning capabilities for student coupled with the learning principles of authentic tasks, learner-centeredness, collaborative learning. This study, after conducted a PBL course for the general art education during the summer semester of 2014, analyzed the result using data collected from students' reflective journals, in-depth interviews, and SNS posts among the students. The result presented students' enhanced self-respect, increased interest in their learning and communication skills, and their recognition of the value on diversity and empathetic attitudes toward each others. In conclusion, PBL showed its potential as an alternative instructional model for the multidisciplinary and convergent learning in college education.

The purpose of this study was to analyze the need for child hospice care in families of children with cancer for outpatient. The participants were 83 parents of children with cancer. This survey was conducted from January 2011 to March 2011 at four hospitals in Daegu. Data were collected through self-report questionnaires and analyzed by descriptive statistics, t-test and ANOVA using the SPSS/WIN Program. Needs for hospice care for the participants were high. The need for "emotional care of children" showed the highest, "control of secondary physical problems", "acceptance of the family's difficulty", "management for terminal physical symptoms", "spiritual care for preparing for death". With respect on the demographic characteristics of the participants, there were statistically significant differences in hospice care needs, among to the religion, sibling, relatives, whether of the cancer. The above findings indicate that needs for hospice care for the participants were high about emotional care, especially as it is related to children's anxiety. Therefore hospice care, based on emotional part, should be provided systematic hospice care with specialized multidisciplinary child hospice care team, child hospice center.

Nowadays, the third-party logistics is getting special attention as one of the most useful ways to perform the logistics management effectively. In this current trend, however, there are many firms which carry out the logistics activities by themselves and strengthen the competitiveness. In respect of contingency theory, the firms' logistics management types should depend on their logistics environment and characteristics, and then the logistics performances vary with this suitability. In this context, this study analyzed empirically the difference of the logistics performances due to the fitness between their logistics characteristics and the management types. According to the finding, the study showed that the third-party logistics is more suitable when the importance and weight of logistics operation and the weight of their export are greater respectively, and the self-logistics is more suitable when the logistics cost is higher. Futhermore, the study indicated that the firms whose relationship between the characteristics and the management types is fit in their logistics are better than the others in the outcome of logistics cost reduction and the effectiveness of logistics operation.

This study examined the effects of elderly people's frail prevention program performed in a senior center located in J-si. The most interesting were the effects on the subjective health status, depression, physical fitness, and quality of life for the senior center participation of the elderly. The nonequivalent control group pre-post-test design was employed. A total of 43 people living in J-si were assigned to either the experimental group (n=22) or control group (n=21). The experimental group was provided with the 8-weeks frail elderly prevention program from September 1 to October 16 in 2015. The data were analyzed with SPSS/WIN 21.0 using descriptive statistics, $x^2-test$, Fisher's exact test, and t-test. The results indicated a significant difference between the experimental group and control group with respect to the scores of the subjective health status (t=-0.35, p=.024), depression (t=2.76, p=.035), physical fitness, including right grip strength (t=-3.10, p=.004) and flexibility of the waist (t=-2.13, p=.039), and the quality of life (t=4.36, p<.001). In conclusion, an elderly people's frail prevention program has a significant effect on the change in subjective health status, depression physical fitness, quality of life, and self-care behavior for senior center participation.
