After its inception in 1994, the Journal of the Microelectronics and Packaging Society has continued to make significant strides in the number and quality of publications within its field. The interest in the microelectronics and packaging research has become more critical as consumer electronic products continue its increasing trend towards thinner and lighter devices that tests the boundaries of electronic devices. This study utilizes social network analysis of all published literature in the Journal for the past 22 years. Using the keywords and abstracts available within each individual article, the publications within the Journal has focused on major topics covering (1) flip chip, (2) reliability, (3) Cu, (4) IMC (intermetallic compounds), and (5) thin film. Using the social network relationship between keywords within articles, flip chip was closely associated with reliability, BGA (ball grid array), contact resistance, electromigration in many of the published research works within the Journal. From the centrality analysis, it was found that flip chip, reliability, Cu, thin film, IMC, and RF (radio frequency) to have a high degree of centrality suggesting these key areas of research have relatively high connectivity with other research topics within the Journal and is central to many of the research fields within the micro-electronics and packaging area. The cohesiveness analysis showed research clustering of five major cohesive sub-groups and was mapped to better understand the major area of research within this field. Research within the field of micro-electronics and packaging converges many disciplines of science and engineering. The continued evolution within this field requires an understanding of the rapidly changing industry environment and the consumer needs.

In addition to the quantitative growth of domestic field placement, there is a growing interest in global field placement and participation of government and universities is increasing. The global field experience of university students provides students with advanced skills and experience of overseas companies as well as opportunities to acquire foreign language ability and global culture suitable for industrial needs that require global competence. Students can cultivate global mind and major practical skills so that it has the advantage of linking to overseas employment. In order to be successful global field placement, the university has to promote to participate in the company including the curriculum related to the student's major and provide comprehensive support including student safety, but the resources of the university are only limited. In this paper, we propose a method to activate global field placement in cooperation with local partner universities based on Kumoh Institute of Technology case study.

Toroidal cores made of metallic powder requires large magnetic field strength up to few decade kA/m to obtain major hysteresis loop. To overcome thermal heat generation problem from large exciting current during measurement, we have employed a real time hysteresis loop tracer which can digitize and calculate B-H signals in personal computer as real time. For example, when we magnetize specimen at 10 Hz frequency, we could display hysteresis loops 10 times per second. Using the real time hysteresis loop tracer, we could measure major hysteresis loop of toroidal shape metallic powder core at maximum flux density or maximum magnetic field strength to be measured within 5 second not to significant increasement of specimen temperature due to the heat dissipation from coil windings. For the constructed hysteresis loop tracer, we could measure hysteresis loop at magnetic field strength higher than 50 kA/m for the toroidal shape specimen.

Major depression is a devastating disorder of which lifetime prevalence rate is as high as up to 25% in general population. Although the etiology of the disorder is still poorly understood, it is generally accepted that both genetic and environmental factors are involved in the precipitation of depression. Stressful lifetime events are potent precipitating environmental factors for major depression and early-life stress is in particular an important element that predisposes individuals to major depression later in life. How environmental factors such as stress can make our neural networks susceptible to depression and how those factors leave long-lasting influences have been among the major questions in the field of depression research. Epigenetic regulations can provide a bridging mechanism between environmental factors and genetic factors so that these two factors can additively determine individual predispositions to major depression. Here we introduce epigenetic regulations as candidate mechanisms that mediate the integration of environmental adversaries with genetic predispositions, which may lead to the development of major depression, and summarize basic molecular events that underlie epigenetic regulations as well as experimental evidences that support the active role of epigenetic regulation in major depression.

The primary objective of this study is to firstly survey and analyze the working environment and actual condition, secondly know their problems, and then provide the basic data about how to improve their working conditions. The specific study items for getting the goal above is as follows: 1. How does the industrial company connect with highschool vocational education well? 2. How does the mechanical technical highschool graduate apply with industrial field? The result of study is as follows: 1. In case of employment's information and the industrial educationed cooperation, the workers who has the working history in less than 5 years takes short to find the job. National high school graduates and those who get the job through the school and the teacher changed their job at short period compared to other. 2. There was no benefit about the same major's worker at industrial field. The workers admitted that there is the exemption fo military service and the certification's allowance, only for which is related to their job. The longer the workers stay their job, the more they had the chance to get the exemption of military service. National highschool were carried out the curriculum well as planed especially for their major subjects. Whereas, the public and private highschools weren't. The seniors of their job and the coworkers are very helpful for learning the actual knowledge. The workers said that the school's curriculum and club activity weren't effective applying with their working field. 3. The study says that the important things of their job is the knowledge of their major. Those who 80% answered that the worker must improve the knowledge of their major to be a good engineer. Learning from their senior in working field was very helpful. The question above was ranked as the first. 4. The answer says that the new changed job's pay is more than the previous job. That is, the reason of leaving the job is the pay gap. The most dissatisfaction and problems in present job was the environment of working and the working condition. 5. Regarding to asking next year's plan, the answer says that keeping the job was ranked as the first. That answer means that they conservative.
