Purpose: The purpose of this study was to investigate the mediating effects of self-esteem and self-resilience while identifying the relationship between bullying victimization (being bullied) and depression based on a longitudinal study design. Methods: Participants were adolescent cohort of 1,971 middle school students participating in 2013 and 2014 Korean Children and Youth Panel Survey conducted by National Youth Policy Institute. Data were analyzed by Pearson's Correlation and regression. Results: The major findings are as follows. First, self-esteem and self-resilience were positively related to each other and negatively related to depression and bullying victimization. Second, bullying victimization effected the level of depression of adolescents and self-esteem played a mediating role between bullying victimization and depression while self-resilience did not. Conclusion: The results suggest that emotional factors continue to play an important role in promoting psychological adjustment of victims of bullying. Therefore, interventions are more likely to be successful if they focus on emotional skills development of adolescents.

Faculty advisors play a vital role in a learning and adjustment process of doctoral students at their work, department, university and discipline by sharing and exchanging relevant information and knowledge in the profession. Despite the important role of information practice in doctoral advising, few studies have investigated the informational aspects of faculty advisors and their students. Thus, this study aims to consider the distribution of information exchanged between faculty advisors and their doctoral students and relate them to doctoral students' demographic characteristics (gender, age, race and/or ethnicity, degree, and stage of doctoral work). The findings of this study show that overall information exchange is most frequent at the work level followed by the discipline, school/department, and university levels. In particular, information exchange at the work and discipline levels explains the characteristics of doctoral education, socializing students into both student and professional roles. In addition, there are statistically significant differences in information exchange along certain dimensions according to the advisee's gender, age, race and/or ethnicity, degree, and stage of doctoral study, suggesting that information needs and seeking behavior may vary according to the demographic characteristics of advisees.

Delay on State-Funded Construction Projects (SFCPs) in Dong Thap - a province in Mekong Delta of Vietnam, as many provinces of Vietnam, have caused budget overrun through many recent years. The budget-overrun situations, in turn, have deepened the delay. Identifying critical factors affecting delay SFCPs plays a key role to mitigate negative impact of delay. 134/160 questionnaires were collected from personals working for project owners, consultants, supervisors and contractors in Dong Thap Province. Convenient sampling method was used. EFA was resulted in critical 04 factors with 20 variables caused delay in SFCPs, including: "Project technic, contractor's financial capacity and adjustment role of the government", "Regulation and Policy", "Mutual benefit support and concern between the government and residents", and "Disadvantage of construction site and weather season". Reliable measures to reduce delay on SFCPs are discussed to establish legal corridors to strictly controlling the process, consider mutual benefit between the government and its residents, and evaluating construction conditions. Those measures are considered could be applied in not only Dong Thap province, but most provinces of Vietnam as well.

This study is about an observation, namely, the starting point of a role creation with playing a bridge role regarding the work of the role at the work with oneself in the actor training program of the stanislavsky school called the bible about the reenactment acting which is the most basic study of the performance, and in the circumstance of theatrical circles of Korea, which relatively have a lack of the research as mentioned earlier, it described the necessity, usefulness and types of the observation as well as methods of a stepwise observation. First of all, actors should capture observing targets suitable for a role in the play, and if the targets were captured, he needs to imitate and then learn it by using his own body In addition, it must go through the process of an extended application by an adjustment, an amplification, and the application depending on the circumstances of the role after understanding the principle of physical behavior. Also, in order to overcome the simple duplication of outward appearance, making it his own should be conducted through the process of learning it by body and identification by attempting empathy, and for become not the process of the observations which can be partially and fragmentarily finished but the whole acts handling the whole play, it requires the actors to continuously make efforts to create the role, designed to be appropriate for the role while comprehensively arranging each behavior of fragmented figures.

It is known that the role of informal support for elderly women is critical to their physical and mental health, adjustment in old age, and their overall life satisfaction. Elderly women's situation such as social losses, widowhood, living alone, and geographic relocation etc. may result in a need for more informal supports for elderly women's health than ever before. Particularly, women's same-sex friendships were rated higher for overall quality, intimacy, enjoyment, and nurturance. Unlike a generally accepted notion that later life for women is a time of isolation and loneliness, elderly women tend to maintain and reestablish their friendship regardless their marital status and living situation. Although studies on informal support for elderly women were inconclusive in many ways, elderly women's friendship tends to be stable despite of changing health status and life events. The relative importance between daughters and friends was also controversial. This study suggests that more research with reliable measurements is necessary for the practical prevention and intervention program of elderly women's health on this issue.

It is important to control the high accurate position and force to prevent unexpected accidents by a robot manipulator. Direct-drive robots are suitable to the position and force control with high accuracy, but it is difficult to design a controller because of the system's nonlinearity and link-interactions. This paper is concerned with the study of the stabilization force control of direct-drive robots. The proposed algorithm is consists of the feedback controllers and the neural networks. After the completion of learning, the outputs of feedback controllers are nearly equal to zero, and the neural networks play an important role in the control system. Therefore, the optimum adjustment of control parameters is unnecessary. In other words, the proposed algorithm does not need any knowledge of the controlled system in advance. The effectiveness of the proposed algorithm is demonstrated by the experiment on the force control of a parallelogram link-type robot.

Power amplifier linearity plays a major role in the design of RF communication systems. In this paper, predistortion type linearizer was designed an independently controllable AM/AM and AM/PM predistortion linearizers. This linearizer allows independent adjustment of the AM/AM and AM/PM curves by using two adjustable voltages to compensate the power amplifier non-linearities. The predistortion linearizer was improved the ACPR by 6dB with cdma2000 multi carrier signals. Applying this linearizer to two-tone 880MHz power amplifier, an improvement of adjacent channel leakage power up to 5dBm has been achieved.

To reduce the cost and the time of transport in Eurasian railroad networks such as TKR(Trans-Korea Railway), TCR(Trans-China Railway) and TSR(Trans-Siberia Railway) owing to the problem of different track gauges (narrow/standard/broad gauge), it is important to develop the gauge - adjustable wheelset system to adapt easily to these gauges. Moreover, this system accomplishes periodically a conversion operation from the gauge variable segment between different gauge. Gauge adjustable compression coil spring during conversion process accomplishes repetitively a central role for operation mechanism between flange and locking part. Therefore, to assure the safety of the gauge-adjustment wheelset system, it is necessary to stress analysis of the optimized spring in the system. In this study, it was performed to optimal design of the spring for stress analysis by using the genetic algorithm.

This experiment was carried out to evaluate the role of oxalic acid metabolism in the incipient decay of brown rotting, and to investigate the effects of various compositions of culture medium. Until 5days incubation, the amount of oxalic acid produced by Tyromyces palustris was increased, while pH was gradually decreased. The difference in oxalic acid production depending on carbon sources was not significant and the pH adjustment of media did not stimulate the production of oxalic acid. In this experiment, hemicellulose was hydrolyzed with 1% oxalic acid, so it is suggested that nonenzymatic acid hydrolysis of hemicelluloses might be involved in the process of incipient decay of brown-rot fungi.
