The purpose of this study was to investigate dietitians or nutrition teachers' perception of sugar reduction and usage of sugars in school meal service. A survey was conducted for dietitians or nutrition teachers at elementary, middle, and high schools in Gyeonggi and Incheon. Survey data were analyzed according to the experience period and school types of dietitians or nutrition teachers. The numbers of subjects according to work experience period were 134 (44.2%) for <5 years, 68 (22.4%) for ${\geq}5$ and <10 years, and 101 (33.3%) for ${\geq}10years$. Among the subjects, 168 (55.4%) were nutrition teachers at kindergarten/elementary schools, and 135 (44.6%) were at middle/high/special schools. Perceptions of sugar reduction programs were higher in kindergarten/elementary schools than in middle/high/special schools. The perception of added sugar use increased with more work experience, and interest in sugar reduction was higher in kindergarten/elementary schools than in middle/high/special schools. Practice for added sugar reduction increased with more work experience, and the most common method for reducing sugar was use of natural sugars. The main reason for not reducing added sugars in school meals was due to preference. Nutritional education for students increased with more work experience and was higher in kindergarten/elementary schools than in middle/high/special schools. The major nutritional education methods were using school homepage (37.4%), sending family letters (37.4%), and using principle's discretion time (18.4%). Organic sugar and rice taffy were used more at kindergarten/elementary schools, and white sugar, brown sugar, and white syrup were used more at middle/high/special schools. The most common menu using added sugars was stir-fried dishes (stir-fried pork, chicken, and vegetables).

The purpose of this study was to identify the preferable motivation types in science-learning and to find out the relationship between these types and scientific achievement of students in the secondary school. The subjects of the study were the second grade 581 students sampled by random cluster sampling method in three middle schools and three high schools. Three motivation types in science learning were analyzed, and they were named to task-orientation, ego-orientation and work-avoidance. From our results, secondary school students preferred task-orientation and work-avoidance to ego-orientation. In the case of task-orientation, high school students, especially in male group, had much preferable tendency than that of middle school students (p<0.001). It is interpreted that, as the level of scientific content of texts or the cognitive level of students were higher, a preference for the motivation type was focused to the task-orientation, especially in male group. In the case of ego-orientation, the female group showed much preferable tendency than that of male group in middle school (p<0.05). However, the female group in high school students was not different from the other groups in this motivation type. In the case of work-avoidance, there were not only a significant difference between males and females in the middle school (p<0.001), but also difference between middle and high school students in female group (p<0.05). It showed that female group had much preferable tendency than that of male group, and this tendency was decreased to the higher grade students in secondary school. From the analysis of correlation between motivation types and scientific achievement, task-orientation and work-avoidance were correlated to the scientific achievement. Its results were interpreted that the scientific achievement could be accomplished by the external motivation stimulus as well as the scientific content of texts. The task-orientation were comparatively correlated to the intelligence quality. It means that the students having high intelligence quality showed much preferable for the task-orientation.

While artificial intelligence is rapidly replacing human jobs, the art field where human creativity is important is considered an exception. There are currently several AI mastering services in the field of mastering music, a profession at the border between art and technology. In general, the quality of AI mastering is considered to be inferior to the work of a human professional mastering engineer. In this paper, acoustic analysis, listening experiments, and expert interviews were conducted to compare AI and human experts. In the acoustic analysis, In the analysis of audio, there was no significant difference between the results of professional mastering engineers and the results of artificial intelligence. In the listening experiment, the non-musicians could not distinguish between the sound quality of the professional mastering engineer's work and the artificial intelligence work. The group of musicians showed a preference for a specific sound source, but the preference for a specific mastering did not appear significantly. In an expert interview, In expert interviews, respondents answered that there was no significant difference in quality between the two mastering services, and the biggest difference was the communication method between the mastering service provider and the user. In addition, as data increases, it is expected that artificial intelligence mastering will achieve rapid quality improvement and further improvement in communication.

This research deals with cognitive characteristics of point symbols on the current tourist maps in terms of the communication theory in considering levels of symbolization and those of preference. The levels of symbolization are examined on the basis of the meaning of point symbols between map-makers and map-users. Preferences of point symbols are investigated by the tourist objects. As a result, when point symbols are expressed in conciseness, the meaning and interpretation about those symbols are highly accorded. And the point symbols that have familiarity by visual experience are preferred. Also, the higher symbolical levels symbols have, the more likely they are preferred. Through that fact, familiarity from the visual experience, conciseness in expression, concreteness of figures expressed in maps, and representativeness of visualized properties were deduced as factors that affect preferences. Those factors work to affect preference complicatedly, but familiarity is prior to simplicity in preferences. Likewise, ways that visualize information, contents that are expressed as images and familiarity in terms of cognitive characteristics make a relative difference in preferences and the levels of symbolization. On the basis of those cognitive characteristics, visual complexity and ambiguity should be removed and the higher symbolical level of point symbols for efficiency of map-reading should be developed.

This study was carried out to assess the characteristics of gabion on road cut-slopes, and analyze the scenic view preference for the gabion in Korea. 97 gabion sites from road cut-slopes were selected and were classified into 10 application types of gabion. The classification types of gabion were mostly related to the erosion and collapse prevention across road cut-slope. Gabion work sites in this study were classified into 30 sites (31%) for below 10% gradient, followed by 31 sites (32%) for 11~30% gradient, 20 sites (21%) for 31~50% gradient, and 16 sites (16%) for 51~80% gradient. Gabion works were constructed mostly in low gradient than in high gradient. 34 gabion sites (35%) among 97 sites were not covered by vegetation and 52 gabion sites (54%) showed vegetation cover rates of 1~30%. On the scenic preference analysis, public groups understood that the scenic view of gabion in cutting slope can be improved by vegetation cover, whereas expert groups prefer to scenic view of gabion only. However, expert groups encouraged subsequently vegetation covering to improve scenic view during gabion works in cutting slope.

The purpose of this study is intended to identify the mediated moderating effect including the mediating effect of job satisfaction and moderating effect of job expectations in the relation between work value, job satisfaction, In this study, the mediating effect of job satisfaction and job preference on the relationship between job value and quality of life were investigated. In this study, questions to measure job value, job satisfaction, and job preference were examined using GOMS data, and data analysis was performed using SPSS 23.0 and SPSS Macro. Since the mediated moderation model is an integrated model that includes mediating and moderating effects, the mediating effect, the moderating effect, and the mediated moderation effect were sequentially verified. As a result of the study, first, it was confirmed that the mediating effect model through job satisfaction was statistically significant. Next, it was confirmed that job value had a statistically significant effect on life satisfaction through the direct path and the indirect path through job satisfaction as a mediating variable. Third, it was confirmed that the moderated mediating effect model of job preference through job satisfaction was statistically significant. In detail, job value as an independent variables and job satisfaction as a mediating variable were found to have a statistically significant positive (+) effect on the dependent variable, quality of life.

The aim of this study is to deduce color temperature and illuminance by conducting the preference & affective evaluation consequent on illuminance change of ambient light in case of the lighting method of ambient light mixed with task light in time of reading which is visual work action among the action in learning space. As a result of the prior survey on preferred lighting method in time of the act of reading targeting 20 experts before doing evaluation, the method of lighting mixed with ambient light and task light was found to be the highest. Such a result is analyzed to be attributable to the fact that the less the difference in illuminance of nearby space and work surface because of the mixed method of lighting, the less the glare, which makes a reader feels easy and concentrate on reading. On the basis of descriptive statistics of evaluation results and impact analysis by category, this study recommends the application of combinations of ambient light illuminance ranging from 40lx to 100lx with color temperature of 5500~6000K in case of the method of lighting mixed with general light and task light.

The purpose of this study was to explore the meaning of work between Asian Americans and white Americans living with mental illness. Employment is important for recovery of Asian Americans with mental illness. However, little is known about reasons of low participation and completion rates on recovery and employment services for Asian Americans with mental illness. Although few studies have suggested that exploring cultural difference is a key to understand these issues, no study have explored how their culture influences a viewpoint on work. Therefore, a study to explore the meaning of work and influences of culture on work is required. This study used both quantitative and qualitative methods. An Internet version of world of work survey was developed based on results of study by Millner(2015) and cognitive interview. The survey was conducted from May to August 2015 and 91 people living with mental illness completed the survey. T-test was used for analyzing qualitative data and researchers analyzed qualitative data. Asian Americans showed higher preference for employment and have more difficulty at workplace and in receiving recovery and vocational services. The findings from this study can inform the development of recovery-oriented employment for people living with mental illness from diverse ethnic groups.
