  • Objective: The aim of this study is to suggest some improvement ideas based on the validity and the reliability analyses of the current safety culture measurement method applied to the Korean nuclear power industry. Background: Wrong safety culture is known as one of the major causes of the disasters such as the space shuttle Columbia disaster or the Fukushima Nuclear Power Plant accident. Assessment of safety culture of an organization is important to build a safer organizational environment as well as to identify the risks hidden in the organization. Method: A face validity of the current safety culture measurement method was analyzed by comparison of the key factors of safety culture in the Korean nuclear power industry with those factors reviewed in the previous studies. The current interview method was analyzed to identify the problems which degrade the consistency of evaluation. Results: Most safety culture factors reviewed in the literatures are covered in the list of the Korean nuclear power industry safety culture factors. However the unstructured questions used in the interview may result in inconsistency of safety culture evaluation among interviewers. Conclusion: This study suggests some examples which might improve the consistency of interviewers' evaluation on safety culture such as a post interview evaluation form. Application: An extended post interview evaluation form might help to increase the accuracy of the interviewing method for Korean nuclear industry safety culture evaluation.

  • Traditional medicine in Asian countries show similarity according to geography, building up their own medical tradition upon indigenous cultural background. Mongolian medicine, in particular, displays district fusion of several medical systems accepted from neighboring countries adding to their traditional system. Those are Mongol Dhom medicine, acupuncture and moxibustion medicine, medicine of "Four Medical Tantras (四部醫典)", and combined system of Mongolian and biomedicine. Compared to East asian medicine, this is a different kind of diversity or hybridity resulting from idiosyncrasy of nomadic culture. Each current of Mongolian medical tradition has its own origin of historical backdrop. Mongol Dhom originated from ancient nomadic life, and medicine of "Four Medical Tantras (四部醫典)" was formed along with transmission of Tibetan Buddhism. Acupuncture and moxibustion is directly related to Chinese medical tradition, however, moxibustion is also referred to be regional origination. Lastly, biomedicine was transplanted during the modernization era, encouraging scientific approach toward Mongolian traditional medicine and producing combined medical practice. It is effective to derive each particular aspects of Mongolian medicine and analyze its specificity, in order to properly understand current Mongolian medical system. This paper aims at discovering socio-cultural meanings of each current and their nomadic feature beneath the diversity.

  • In this study, the high current behaviors and double snapback mechanism of gate grounded_extended drain n-type MOSFET(GG_EDNMOS) device were analyzed in order to realize the robust electrostatic discharge(ESD) protection performances of high voltage operating display driver IC(DDIC) chips. Both the transmission line pulse(TLP) data and the thermal incorporated 2-dimensional simulation analysis as a function of ion implant conditions demonstrate a characteristic double snapback phenomenon after triggering of bipolar junction transistor(BJT) operation. Also, the background carrier density is proven to be a critical factor to affect the high current behavior of the GG_EDNMOS devices.

  • In the measurement of atmospheric static electric field, it is important to know characteristics of corona discharges caused at the tip of test electrode. This paper presents the fundamental data of DC corona discharges that occurred at the tip of a needle-shaped electrode placed in the homogeneous background electric field which simulates the atmospheric static field under thundercloud. The major characteristics of interest for this purpose are the polarity effect of corona discharges and the magnitudes and time intervals of corona current pulses. The experimental set-up consists of the plate-to-plate configuration with a needle-shaped protrusion, DC power supply, and voltage and current measuring devices. As a result of experiments, the polarity dependence of corona pulses is significantly pronounced. The time intervals between successive corona pulses in the negative polarity is much longer than those in the positive polarity. The time intervals for both polarities is drastically decreased as the applied electric field is increased. Also the magnitudes of the positive corona pulses are slightly changed with an increase in applied electric field, but those of the negative corona pulses are linearly increased with increasing the applied electric fields.

  • This study conducted a survey on 163 parents in Korea to investigate their interest in plants, experience in growing plants, and perception on horticultural activity programs (HAP) for their children. Most children (80.4%) of the respondents had experience participating in HAPs, and most of their experience occurred during school hours in preschool educational institutions more than once a month (60.3%). The more interest in plants and experience in growing plants the parents had, the more experience the preschoolers had in participating in HAPs, which implies that the experience of the parents with plants affected their children's participation in HAPs. Parents' most preferred location of HAPs was preschool educational institutions, and most preferred time was school hours with a frequency of more than once a week (57.1%), which is more frequent than the current status of HAPs in preschool educational institutions. Parents also responded that the most preferred instructors of HAP has are those with a professional background in horticulture. Among the activities in HAP for preschoolers, parents most preferred cooking (M = 4.05) activity, and they did not dislike any of the activities. They responded that the facilities for HAP needed to be improved to make HAP more active in preschool educational institutions. Overall, based on the current results, developing suitable HAPs and facilities for preschoolers, fostering professional HAP instructors, and educating parents about horticulture would enhance HAPs in preschool educational institutions, thus providing preschoolers with many benefits of HAPs.
