  • We developed a PC-based 8-channel electrical stimulation system for transcutaneous functional electrical stimulation (FES), and applied it to FES exercise and paraplegic walking. The PC program consists of four parts: a database, a stimulation pattern generator, a stimulus parameter converter, and an exercise program. The stimulation pattern can be arbitrarily generated and edited by using the mouse on the PC screen, and the resulting stimulus parameters arc extracted from the recruitment curves, and transmitted to the 8-channel stimulator through the serial port. The stimulator has nine microprocessors: one master and eight slaves, Each channel is controlled by the slave microprocessor, and is operated independently. Clinical application of the system to a paraplegic patient showed significant increase in the knee extensor torque, the fatigue resistance, and the leg circumference, The patient can now walk about 50 meters for more than 2 minutes.

  • Ocean climate variables ($1900{\sim}2005$), time series of catches ($1910{\sim}2005$) and body size data were used to assess the year-to-year and decadal scale fluctuations in abundance of the fish populations (Japanese sardine, anchovy, jack mackerel, chub mackerel, Pacific saury and common squid) that have spawning grounds in the East China Sea and its adjacent regions. A negative correlation between the abundance of pelagic fishes (e.g. jack mackerel) in the Tsushima Warm Current (TWC) region and the Kuroshio-Oyashio Current (KOC) region was attributed to the climatic modulation of larval transport and recruitment, which depends on the winter monsoon-induced drift, current systems, and spawning season and site. The changes in abundance and alternation of dominant fish populations in the two regions in the 1930s, 1970s, and late 1980s mirrored changes in the climate indices (ALPI, AOI and MOI). Oscillations in the decadal climate shifts between the two regions led to zonal differences in larval transport and recruitment, and hence differences in the abundance of the pelagic fish populations. During deep Aleutian Lows, as in the 1980s, larval transport from the East China Sea to the KOC region increases in association with the strong winter Asian monsoon, cool regime and increased volume transport of the Kuroshio Current systems, whereas during a weak Aleutian Low (as in the 1990s), larval transport to the TWC region increased in association with a weak winter Asian monsoon, a warm regime, and increased volume transport of the Tsushima current system. We postulate that the increased chub mackerel abundance in the TWC region and the decreased abundance in the KOC region in the 1990s are partly attributed to changes in recruitment and availability to the fishing fleets under the warm regime in the spawning and nursery grounds in the East China Sea in association with the quasi-steady state of mild winter monsoon in the 1990s. The fluctuations in chub mackerel and jack mackerel abundance are under the environment-dependant growth form, although the tropicalization was identified in the TWC region. The density-dependant growth form was found in Japanese sardine populations, but no tropicalization by fishing was identified in the long ($10{\sim}15$ year) periods of abundance despite their short ($3{\sim}4$ year) generation time, suggesting that the environment-dependant growth form drove the changes in abundance. Year-to-year and decadal scale variations in abundance and population structure of the Pacific saury responded to climate regime shifts (1976/1977, 1988/1989), suggesting that the fish is a key bio-indicators for changes in the ecosystem.

  • The Ministry of Health and Welfare proposed the "undergraduate program specializing in pharmaceutical industry" in 2013, as part of its roadmap to assist domestic pharmaceutical companies to become the top-tier pharma companies in near future and provide skilled personnel tailored for pharmaceutical industry. However, it is not clear whether this "undergraduate program" meets the needs of pharmaceutical industry, especially when the number of pharmacy students increased from 1,200 to 1,700 per year since 2009. The purpose of this paper is to identify which educational background is preferred by pharmaceutical companies, by surveying the CEOs of domestic pharmaceutical companies and referring to recruitment advertisements shown in medical newspapers, specified by the fields within the companies. Two independent reviewers referred to recruitment session in Yakup newspaper and Dailypharm from May 2012 until January 2014, focusing on recruitments from pharmaceutical companies targeting bachelors' degree holders with no prior experience. 749 recruitments were observed during the study period, more than 90% of which were provided by domestic pharmaceutical companies, and regardless of the companies being domestic or multinational, pharmaceutical companies' preference for pharmacists was remarkable (44.3% for domestic and 65.8% for multinational), and the preference was especially high in the fields such as Medical, R&D, Market Access (regulatory affair/pricing and reimbursement), Business Development, and Marketing. Survey results showed that the need of establishing the undergraduate program specializing in pharmaceutical industry is mixed, suggesting that although there is need for the educating personnel targeting pharmaceutical industry, the undergraduate program would not be an answer due to current PEET system. Our study concludes that in the example of pharmaceutical companies' recruitments shown in medical newspapers, pharmaceutical companies prefer pharmacy major in almost all fields of the pharmaceutical companies, yet the pharmaceutical companies still perceive the gap between current bachelor's degree holders(including pharmacy majors) and the ideal personnel required for advancing to the "top-class" pharmaceutical companies.

  • In most of the medical literature that discusses the common problem of movement in patients with cerebral lesions. This critical problem is ascribed to a mechanism involving uninhibited neural activity. The goals of neurological physical therapy are focus on reduce of muscle hypertonicity, facilitates muscle activities, and improve of performance in living environment. A variety of studies suggest that spasticity is a distinct problem and separate from the muscle weakness. It has become increasingly recognized that the major functional deficits following brain damage are largely due to negative features such as muscle weakness and loss of performance rather than spasticity. Adequate recruitment of prime mover, not release was able to carry out the movement tasks well. The strengthening exercise of spastic limbs on changes in muscle properties and performance skill, the repeated motor practice has been identified as crucial for motor recovery. This article support the concept that strengthening is an appropriate intervention to improve the quality of physical function in patients with central nervous system lesions. Further studies and therapeutic approaches should be efforts at improving motor neuron recruitment in agonist rather than reducing activity in antagonists while retraining muscle strengthening.

  • Since South Korea has problems existing in the respects of educational resources, environment, policies, etc., local universities of South Korea have been in an inferior position in the competition of overseas student enrollment. With increasingly deepening of cultural exchange between China and South Korea, due to geographic close relationship between the two countries, a great number of South Korean students go to China for study; also, Chinese students have increasingly become the important target of recruitment by all local universities in South Korea. In recent years, with rapid increase in the number of Chinese students in South Korea, the overseas student education system of South Korea has been progressed continuously. Compared with educational advantages of universities in European, American developed countries, and the capital region of South Korea, however there still exists a lot of problems in Chinese student recruitment by local universities. The major findings of the study can be summarized as follows. There exist not only some advantages but also some problems to be addressed urgently in Chinese student enrollment by South Korean local universities. How to build a distinctive recruitment environment suitable for Chinese students; and, how to develop a complete "one-stop" educational system suitable for study; and, how to make a strategy of development for Chinese students; and, how to perfect set up the overseas students' education management system; which are the remaining tasks to be solved for. To achieve a win-win for both overseas students and South Korean local universities, it is very important and urgent works to do for administrators of Chinese students in all local universities of South Korea.

  • Objectives: The present study was designated to evaluate the direct effects of Fructus Liquidambaris on suppression of eosinophil activity and on suppression of chemokines such as eotaxin, IL-8, ICAM-1, and VCAM-1, in vitro. Methods: A549 cells were stimulated with TNF-$\alpha$ (100 ng/ml), IL-4 (100 ng/ml) or IL-$1{\beta}$(10 ng/ml) to induce chemokines and adhesion molecules involved in eosinophil chemotaxis. Then after treatment of Fructus Liquidambaris, inhibition effect assay such as ELISA, real-time RT-PCR, and chemotaxis assay was performed. Results: Eotaxin level was suppressed in both protein secretion and mRNA expression. Eosinophil recruitment to lung epithelial cells was also reduced by Fructus Liquidambaris, implying the role of eotaxin in eosinophil recruitment. In addition, expression of IL-8 was also suppressed by Fructus Liquidambaris (p<0.05). However, expression of adhesion molecules (ICAM-1, VCAM-1) related to eosinophil was not affected. The eosinophil migration was inhibited at high concentration of Fructus Liquidambaris (p<0.05). Conclusion: These results suggest that Fructus Liquidambaris may regulate a common signaling pathway of eotaxin and IL-8. FS might be of therapeutic value in diseases such as asthma.

  • The purpose of this study is to investigate the status of admission and employment in fisheries high schools (FHS) and to consider ways to revitalize FHS through substantialization. The recruitment rate of new students in FHS decreased from 97.4% in 2016 to 83.2% in 2020. The aging training ship that FHS needs to improve most urgently is being jointly used by FHS across the country, and the construction of a joint training ship managed by the Korea Institute of Maritime and Fisheries Technology is being promoted. The average employment rate for FHS by year was 40.2-59.4%, and the fisheries-related employment rate was low at 31.0-38.9%. On the other hand, the acquisition rate of certificate of competence was 37.5-52.0%, and the rate of employment on board of those who obtained the certificate of competence was 42.9-59.8%. In order to secure new students and improve the recruitment rate, we operate experiential classrooms that reflect the characteristics of training ships and departments and conduct public relations activities using sns, publicity video ucc, YouTube, etc. It will be necessary to expand opportunities for fisheries-related vocational experience through active career exploration and elective courses in the FHS credit system. Finally, it is judged that fisheries related government agencies, industries and local governments need to improve their awareness of FHS and plan to support fisheries manpower nurturing in order to attempt the vitalization of FHS.
