This study aims to identify effects of outplacement support program for discharged soldier to settle and adapt successfully in Ministry of Patriots and Veterans Affairs. The subject of this study are 323 discharged soldiers who completed the outplacement support program. A survey questionnaire is conducted to measure variables of this study. All data analysis is accomplished using the AMOS 7.0 version. The results of this study are as follows. First, learning motivation has direct effect on learning flow and program satisfaction positively. Second, organizational support has direct effect on program satisfaction, psychological stability positively and on learning flow negatively. Third, outplacement support program has direct effect on learning flow, program satisfaction, job-seeking efficacy and psychological stability positively. Fourth, learning flow has direct effect on program satisfaction positively but don't have direct effect on job-seeking efficacy and psychological stability significantly. Fifth, learning motivation, outplacement support program has direct effect on job-seeking efficacy and psychological stability with partial mediation effect of program satisfaction while without mediation effect of learning flow. Based on the results of the study, the following recommendations have been made. First, it is necessary to design the outplacement support program with contents in relation to discharged soldiers' successful settlement because discharged soldiers who completed the outplacement support program showed higher job-seeking efficacy and psychological stability. Second, it is needed to conduct a longitudinal study considering other variables such as employment, establishment success etc.

This study purposed to analyze how teacher experience of instructional change (EIC), teacher morale (TM), and school climate (SC) mediate or moderate the relationship between teacher efforts on instructional improvement (EII) and teacher efficacy (TE). For the purpose, the 6th year data of Gyeonggi Education Panel Study (GEPS) which was administered in 2017 for the 9th grade students and their teachers from 197 middle schools in Gyeonggi Province was used. As results, the mediation effects of EIC on the link between EII and TE was found only under the innovative climate. The moderation effects of TM on the connection between EIC and TE were appeared in both of the permissive and the innovative climate. Finally, the moderated mediation effects of the TM in the innovative climate were bigger rather than in the permissive climate.

The purpose of this study was to identify the latent profiles according to the core competencies of middle school students and to examine whether the parent-child relationship predicts the latent profiles based on the core competencies for students defined by the Korean Ministry of Education. To achieve the purpose of the study, a total of 6,065 second-year middle school students were analyzed from the fourth year of the Korean Educational Longitudinal Study (KELS 2013), which was conducted by the Korean Educational Development Institute in 2016. The results of latent profile analysis and multinomial logistic regression are as follows. First, three latent profiles (higher competency group (19.54%), middle competency group (49.03%), and lower competency group (31.43%)) were derived according to the core competencies. For all groups, the highest competency was communication ability, and the lowest was creative ability. Second, the variables of the parent-child relationship (i.e., parental academic support, emotional support, and attachment level) were significant in predicting differences among the core competency latent profiles. In particular, the emotional support of parents was found to have the greatest influence on the core competencies of middle school students. This study identified the influence of the parent-child relationship on the development of core competencies. Further, it showed that a good family relationship is important for the holistic development of adolescents.

Purpose: This study was conducted in order to develop morning bread using powdered citrus peels and to examine the effect of its several biological activities for 12 weeks in overweight adults ($$BMI{\geq_-}23$$) living in dormitories of Chonbuk National University. Methods: Control bread was prepared using the same formula except for replacing the wheat flour with 3% citrus peel powder. Subjects were classified according to two groups: Intake group of 3% citrus peel powder fortified morning bread (n = 30) and general morning bread (n = 30). Results: The results of our study showed no significant effects of citrus peel powdered morning bread on anthropometric indices and biochemical characteristics among overweight adults. Despite the slight reduction in total-cholesterol, LDL-cholesterol, GOT, and GPT (p < 0.05), no significant differences in changes of these values were observed between the two groups. Conclusion: The short duration of our intervention might have resulted in the lack of any significant effect. Therefore, conduct of further studies with longer duration is warranted in order that the results from this study can be utilized as a basis for the development of food products with citrus peel powder.

The purpose of this study is to convergence approach analyse the depression tendency by family situation and leisure history in the elderly who live in town house in Gyeonggi-do. This study analysed factors such as family situation, leisure history related to the depression tendency. This study selected 20 elderly people over 65 as research subjects and all data analysis was to conduct analyze by multi-variables independent t-test and one-way ANOVA. The results of GDS showed 11 people(55%) presented with mild depression tendency(M=13.0) and 1 person(5%) showed severe depression tendency. 11 out of 30 questions in GDS had a significant difference among the depression degree. Individual disease type had a significant difference in depression tendency statistically(F(3, 16)=4.534, p<.05). Past leisure satisfaction among total leisure history factors had a significant difference in depression tendency(F(2,17)=3.989, p<.05). The participants whose leisure activity was absent in the past and present showed a regressive depression tendency. Participants with no social companions also presented with the same. The study concluded to grasp the real condition of depression, and make practical alternatives for that, multilateral depression tendency analysis using diverse methods are necessary in the near future for improving reliability of tools.

As the number of multimedia applications increases, various protocols and architectures have been proposed to provide QoS(Quality of Service) guarantees in the Internet. Most of these techniques, though, bear inherent contradiction between the scalability and the capability of providing QoS guarantees. In this paper, we propose a protocol, named DQSP(Dynamic QoS Support Protocol), which provides the dynamic resource allocation and admission control for QoS guarantees in a scalable way. In DQSP, the core routers only maintain the per source-edge router resource allocation state information. Each of the source-edge routers maintains the usage information for the resources allocated to itself on each of the network links. Based on this information, the source edge routers perform admission control for the incoming flows. For the resource reservation and admission control, DQSP does not incur per flow signaling at the core network, and the amount of state information at the core routers depends on the scale of the topology instead of the number of user flows. Simulation results show that DQSP achieves efficient resource utilization without incurring the number of user flow related scalability problems as with IntServ, which is one of the representative architectures providing end-to-end QoS guarantees.

The aim of this study was to examine growth trajectories of delinquent behaviors during adolescence. In addition, the effects of protective and risk factors that might account for individual difference in the level of delinquent behaviors and in the rate of change were examined. Four waves of data in the Korea Youth Panel Survey(KYPS) were used to analyze the linear growth modeling. The sample consisted of 3346 adolescents who were assessed at 4 measurement waves with approximately 1-year intervals. The results showed significant individual differences in both final level of delinquent behaviors and in the rate of change across 3 measurement occasions. Adolescent gender, family's socioeconomic background predicted the final level and the rate of change of delinquent behaviors. The protective effects of positive parenting and self-control were significantly associated with problem behaviors and the risk effects of the association with deviant peers and negative stigma were significant on the final level of delinquency. Self-control and deviant peer affiliation had differential influences over time significantly. Practice and policy implications as well as further research topic were discussed in the light of searching for important factors in preventing adolescent problem behaviors.

Previous researches on automatic spacing of Korean sentences has been researched to correct spacing errors by using n-gram based statistical techniques or morpheme analyzer to insert blanks in the word boundary. In this paper, we propose an end-to-end automatic word spacing by using deep neural network. Automatic word spacing problem could be defined as a tag classification problem in unit of syllable other than word. For contextual representation between syllables, Bi-LSTM encodes the dependency relationship between syllables into a fixed-length vector of continuous vector space using forward and backward LSTM cell. In order to conduct automatic word spacing of Korean sentences, after a fixed-length contextual vector by Bi-LSTM is classified into auto-spacing tag(B or I), the blank is inserted in the front of B tag. For tag classification method, we compose three types of classification neural networks. One is feedforward neural network, another is neural network language model and the other is linear-chain CRF. To compare our models, we measure the performance of automatic word spacing depending on the three of classification networks. linear-chain CRF of them used as classification neural network shows better performance than other models. We used KCC150 corpus as a training and testing data.
