  • Objective: The aim of this study is to develop management guidelines and a procedure for an anthropometric suitability assessment of the main control room (MCR) in nuclear power plants (NPPs). Background: The condition of the MCR should be suitable for the work crews in NPPs. The suitability of the MCR depends closely on the anthropometric dimensions and ergonomic factors of the users. In particular, the MCR workspace design in NPPs is important due to the close relationship with operating crews and their work failures. Many documents and criteria have recommended that anthropometry dimensions and their studies are one of the foremost processes of the MCR design in NPPs. If these factors are not properly considered, users can feel burdened about their work and the human errors that might occur. Method: The procedure for the anthropometric suitability assessment consists of 5 phases: 1) selection of the anthropometric suitability evaluation dimensions, 2) establishment of a measurement method according to the evaluation dimensions, 3) establishment of criteria for suitability evaluation dimensions, 4) establishment of rating scale and improvement methods according to the evaluation dimensions, and 5) assessment of the final grade for evaluation dimensions. The management guidelines for an anthropometric suitability assessment were completed using 10 factors: 1) director, 2) subject, 3) evaluation period, 4) measurement method and criteria, 5) selection of equipment, 6) measurement and evaluation, 7) suitability evaluation, 8) data sharing, 9) data storage, and 10) management according to the suitability grade. Results: We propose a set of 17 anthropometric dimensions for the size, cognition/perception action/behavior, and their relationships with human errors regarding the MCR design variables through a case study. The 17 selected dimensions are height, sitting height, eye height from floor, eye height above seat, arm length, functional reach, extended functional reach, radius reach, visual field, peripheral perception, hyperopia/myopia/astigmatism, color blindness, auditory acuity, finger dexterity, hand function, body angle, and manual muscle test. We proposed criteria on these 17 anthropometric dimensions for a suitability evaluation and suggested an improvement method according to the evaluation dimensions. Conclusion: The results of this study can improve the human performance of the crew in an MCR. These management guidelines and a procedure for an anthropometric suitability assessment will be able to prevent human errors due to inadequate anthropometric dimensions. Application: The proposed set of anthropometric dimensions can be integrated into a managerial index for the anthropometric suitability of the operating crews for more careful countermeasures to human errors in NPPs.

  • The elderly is a target group for health functional foods (HFFs). We surveyed 825 Korean elderly (71.4- years-of-age) for HFF use and significant variables for HFF use including demographic characteristics, health related variables, and nutritional beliefs. The prevalence of HFF use was 48.7%, and among all types of HFF, red ginseng products were eaten most frequently, followed by ginseng products, nutritional supplements, and mushroom products. The mean age of users of HFFs was lower than nonusers (p<.01). HFFs were eaten more frequently by subjects from families living with a spouse or unmarried children (p<.01) and those with higher levels of monthly pocket money (p<.001). HFFs were also eaten more frequently by subjects or their spouses with a higher education level (p<.001). The social activity participation ratio (p<.01) of subjects and the HFF usage ratio by the spouse (p<.001) were higher in users of HFF than in nonusers. Dietary assessment scores were not different between the two groups, and users had a more positive view concerning the potential health benefits of HFFs than did nonusers (p<.001). Most users of HFF ate HFFs "when they were healthy" (52.2%) and experienced some effect through HFF use (45.8%). Most users of HFFs received information on HFFs through their families or relatives (38.1%) and most purchased HFFs at the pharmacy or oriental medicine clinic (44.8%). HFF users preferred multivitamin- and Ca-supplements most among the vitamin and mineral supplements belonged to HFFs. The above results show that HFF use is widely spread among subjects, and that use of HFF is influenced by various factors. Thus, practical guidelines for HFF use should be provided for the elderly through elderly focused-nutrition education based upon significant variables and consumption behaviors for their HFF use of present study.

  • Various types of health functional foods (HFF) are popularly used among middle-aged. We surveyed 946 middle-aged in Korea for HFF use and significant variables for their HFF use including demographic characteristics, health related variables and nutritional beliefs. The use prevalence of HFF was 58.9%, and among all types of HFF, red ginseng products were taken most frequently, followed by nutritional supplements, ginseng products > mushroom products. HFF was taken more frequently in subjects from high monthly family income (p < .001), and in those from families with a high socioeconomic status (p < .001) in comparison to each corresponding group. Mean age of users was higher than nonusers (p < .001). Self concern about health (p < .001) and usage ratio of HFF by family (p < .001) were higher in users than in nonusers of HFF. Total dietary assessment score was not different in two groups, and users had a more positive view concerning the potential health benefit of HFF than nonusers (p < .001). Most users of HFF took HFF when they were healthy (52.8%) and experienced a little effect through the HFF use (51.2%). Most users of HFF obtained the information on HFF through family and relatives (30.5%) and most of them purchased HFF at pharmacy or oriental medicine clinics (44.5%). HFF users preferred multivitamin and Ca-supplements most among the vitamin mineral supplements belonged to HFF. Given the widespread use of HFF and inappropriate usage of HFF among subjects, the proper use of these products for the contribution to their optimal nutrition and overall health is a subject that should be formed through practical nutrition education considering the various variables affecting their HFF use.

  • A kindergarten requires an approach to meet the nature and sense of children who is main users. This study selected 33 private kindergartens which were located within a housing site development zone in Gwangju since the 1990's, had single use, and was constructed in the last five years. Also the image assessment according to types of color scheme was made. Then the factors which affected preference by type were analyzed and the basic of color scheme in a kindergarten classroom was provided. The following results were obtained. First, types of color scheme in a classroom included identity 12.1%, similarity 51.5%, and novelty 36.4% in harmony, but no contrast and achromatic color, Secondly, the assessment of preference according to each type was mostly positive. The highest preference was found in similarity harmony of warm color(e.g. YR, Y) and bright, clear, nice, and strong images were high in assessment. The lowest preference was found in identity harmony of cold color(e.g. GY). This color system had no clear image assessment, except manly or strong. In particular, warm color showed higher preference than cold color in similarity, novelty, and identity harmony. Thirdly, the factors affecting the preference of color scheme in a classroom most were ‘stable - unstable’, ‘clean - dirty’, ‘bright - dark’, ‘nice - not nice’, and ‘vital - dull’.

  • 직업재활은 장애인이 직업을 통하여 비장애인과 동일한 삶을 영위하게 돕는 과정으로 정확한 직업평가를 통해 수행된다. 이러한 직업평가의 전통적인 방법은 평가도구를 사용하거나 상담 등을 이용한다. 하지만 전통적인 방법에서 사용되는 평가도구들은 일반 사용자들이 사용하기에는 고가이며, 이러한 평가도구를 사용하기 위해서는 보유하고 있는 장애인시설로 이동해야하는 불편함이 있다. 따라서 최근 꾸준히 보급되어 2012년 이용자수가 3천만명을 돌파할 것으로 예상되는 스마트폰을 사용하여 장애인이 직접 직업평가를 수행하는 경우에 시 공간에 제약을 받지 않아 매우 효율적이다. 본 논문에서는 스마트폰용 운영체제의 일종인 안드로이드환경에서 장애인들을 대상으로 직업평가를 수행할 수 있는 모바일 적성검사 시스템을 설계하고 구현한다. 직업평가 도구로서는 전 세계적으로 진로지도와 상담에서 가장 많이 사용되고 있는 홀랜드 검사를 바탕으로 구현한다.

  • A successful deployment of multimedia applications over wireless environments entails improving the quality of service (QoS), not only from a technical point of view, but also considering the quality of experience (QoE) from the final user's perception. Although objective QoE measure models avoid the difficulties of subjective surveys, subjective QoE assessments are essential to understand the way users evaluate the QoS. In this work, we study the effect of a wide range of parameters on the QoE of VVoIP applications in a real wireless scenario. Through a complete statistical analysis of users' ratings, we identify the following facts. Although the use of VVoIP in wireless networks does not yet represent an advantage for users, there are great expectations for all applications under study, and with greater popularity comes higher expectations. It is easier for respondents to identify good behavior than poor behavior. Whereas the respondents' frequency of Internet use does not impact on the scores, respondents' gender does. Finally, the most determining parameters of quality from a user's perspective were instability, video quality, voice distortion, usefulness, and graphical interface.
