The purpose of this study is to seek out efficient multicultural education plans by investigating Home Economics teachers' perception of multicultural families and multicultural education. Thus, a survey was carried out to collect data mainly from home economics teachers who is working for middle schools. The results of this study can be summarized as follows. Firstly, there were more teachers who had some experience of contacting with multicultural families than those who didn't have, but it was not a big difference. Also, it was found that there were not many teachers who took multicultural education-related classes for their studying at college or had multicultural education-related teachers' training for their working as a teacher. Secondly, it was found that their respect for multi-races, recognition of multi-cultures, belief in multi-cultures and acceptance attitude toward multicultural knowledge were very positive. Thirdly, it was found that most teachers had consideration -centered viewpoints most of all. On the other hand, assimilation-based viewpoints were the least among teachers. Fourthly, teachers believe that multicultural society centered contents, which is a society where people get along with each other, should be dealt in class while executing education for multicultural families. Lastly, in regard to methods of executing education for multicultural families, it was found that they showed the strongest opinion that it should be executed all over the domain of every school subject as integrated education.

The purpose of this study is to obtain basic data for constructing a modeling practice program integrated with meta-modeling knowledge by analyzing the cognition level for each meta-modeling knowledge components through modeling practice in the context of the chemistry discipline content. A chemistry teacher conducted inquiry-based modeling practice including anomalous phenomena for 16 students in the second year of a science gifted school, and in order to analyze the cognition level for each of the three meta-modeling knowledge components such as model variability, model multiplicity, and modeling process, the inquiry notes recorded by the students and observation note recorded by the researcher were used for analysis. The recognition level was classified from 0 to 3 levels. As a result of the analysis, it was found that the cognition level of the modeling process was the highest and the cognition level of the multiplicity of the model was the lowest. The cause of the low recognitive level of model variability is closely related to students' perception of conceptual models as objective facts. The cause of the low cognitive level of model multiplicity has to do with the belief that there can only be one correct model for a given phenomenon. Students elaborated conceptual models using symbolic models such as chemical symbols, but lacked recognition of the importance of data interpretation affecting the entire modeling process. It is necessary to introduce preliminary activities that can explicitly guide the nature of the model, and guide the importance of data interpretation through specific examples. Training to consider and verify the acceptability of the proposed model from a different point of view than mine should be done through a modeling practice program.

Purpose: This study aims to evaluate the recognition, purchase, and intake status of edible insects in adults, who are the main consumers of edible insects, and to provide the information necessary to expand the production and consumption of edible insects and related products in the future. Methods: A total of 453 adults (172 males and 281 females) aged 19 years and older were surveyed regarding their awareness of edible insects, purchase and consumption experience, and intention to purchase and consume, and the differences between them were analyzed according to gender and age groups. Data collection took place from December 2018 to January 2019. Results: Those who had knowledge of edible insects accounted for 87.0%, whereas those who had more than average knowledge were 75.9%, suggesting recognition was relatively high. Men had more experience than women in purchasing or consuming edible insects and related products (45.9% vs. 31.0%, p < 0.01). In terms of age, experience was 22.5% in 20-30s, 44.6% in 40-50s, and 63.1% in 60s and older, showing significant growth as age increased (p < 0.001). The satisfaction level of edible insects was highest in taste (3.4 points), and especially for shape and appearance, it decreased as age reduced (p < 0.001). The most common reason for not being willing to use edible insects was feeling repulsive (4.1 points), which was significantly more common in women than in men (4.3 vs. 3.9, p < 0.001), and lower with age (p < 0.001). The most needed information display for using edible insects was country of origin (63.8%), the main nutrient in edible insects was protein (93.6%), and the most preferred form of products was powder (39.5%). Conclusion: According to the above results, the recognition of edible insects was high, whereas experience of using edible insects and intention to use edible insects were low especially in women and younger groups. The reason for this is that consumers are dissatisfied with edible insects due to their appearance. This study is expected to be used as basic data for expanding the production and consumption of edible insects and related products in the future.

Companding algorithms have been used to enhance speech recognition in noise for cochlea implant users. The efficiency of using companding for digital hearing aid users is not yet validated. The purpose of this study is to evaluate the performance of the companding for digital hearing aid users in the various hearing loss cases. Using HeLPS, a hearing loss simulator, two different sensorinerual hearing loss conditions were simulated; mild gently sloping hearing loss(HL1) and moderate to steeply sloping hearing loss(HL2). In addition, a non-linear compression was simulated to compensate for hearing loss using national acoustic laboratories-non-linear version 1(NAL-NL1) in HeLPS. In companding, the following four different companding strategies were used changing Q values(q1, q2) of pre-filter(F filter) and post filter(G filter). Firstly, five IEEE sentences which were presented with speech-shaped noise at different SNRs(0, 5, 10, 15 dB) were processed by the companding. Secondly, the processed signals were applied to HeLPS. For comparison, signals which were not processed by companding were also applied to HeLPS. For the processed signals, log-likelihood ratio(LLR) and cepstral distance(CEP) were measured for evaluation of speech quality. Also, fourteen normal hearing listeners performed speech reception threshold(SRT) test for evaluation of speech intelligibility. As a result of this study, the processed signals with the companding and NAL-NL1 have performed better than that with only NAL-NL1 in the sensorineural hearing loss conditions. Moreover, the higher ratio of Q values showed better scores in LLR and CEP. In the SRT test, the processed signals with companding(SRT = -13.33 dB SPL) showed significantly better speech perception in noise than those processed using only NAL-NL1(SRT = -11.56 dB SPL).

In this study, I compare the ability of alternative accounting method for employee stock option to reflect firm value using the Ohlson's(1995) valuation model for 200 firms. The each methods, I compare are employee stock option expense recognition based on the K-GAAP disclosures, and asset recognition at the grant date based on the SFAS No. 123 Exposure Draft: Accounting for stock-based compensation. The model include: (1) a model that uses reported earnings, equity book value, and compensation expense based on the K-GAAP disclosures; (2) a model that uses pro-forma earnings, equity book value and adds a measure of the unrecognized asset arising form granting of employee stock options. Finding form estimating equations that the K-GAAP method for calculating compensation has no explanatory power, and the SFAS No.123 Draft Exposure method for arising asset and fair value compensation better captures than market's perception of the economic impact of stock options on firm values. However, the correlation of employee stock option compensation expense is positive. These results suggest that incentive benefits derived from employee stock option plans outweigh the cost associated with plan. In addition, I couldn't find evidence that company in KOSDAQ that have high growth potential benefit more from employee stock option plan compared to lager, more mature firm in SEC.

Conditions related to body composition and aging, such as osteopenic obesity, sarcopenia/ sarcopenic obesity, and the newly termed osteosarcopenic obesity(triad of bone, muscle and adipose tissue impairment), are beginning to gain recognition. Currently, it has begun to attract the attention of scholars from all over the world, however, for this disease, it still needs a more clear understanding and perception. Therefore, this article considered the osteoporosis, muscle depression, and obesity, these diseases as a gate to study the relationship among muscle, bone, and fat. In addition, in the aging process, the formation of IGF-cortisol, testosterone, and estrogen is sensitive. These hormones can not only absorb muscle protein metabolism, but also affect alienation. The decrease in IGF-cortisol in the elderly resulted in increased visceral fat, decreased muscle mass and bone mineral density, and then affected decreased skeletal muscle atrophy and decreased quality. The reduction of skeletal muscle quality and strength and increase body fat affected the adipose tissue to produce inflammatory cytokines, thereby reduced skeletal muscle, promoted cardiovascular disease, metabolic syndrome and insulin resistance in chronic diseases. Almost all chronic inflammatory diseases were associated with bone, muscle and fat. These mechanisms were complex and interrelated. Inflammation reduces bone formation, increases fat and reduces muscle mass. And thus not only had a significant impact on the motor system, but also made the incidence increase of fracture, osteoporosis, fragile syndrome, fall, osteomalacia and other bone disease. This article aimed to start from the interaction between the muscles and bones of the elderly, extended to obesity, muscle deficiency, osteoporosis and other diseases, finally, from a nutritional point of view, to discuss how to treat osteoporosis obesity.

The purpose of this study was to reduce safety accidents among food employees in contracted foodservice management companies, and to help provide high-quality foodservice and assistance. For this, a survey on the different opinions of workplace safety and education by employment type and employee perceptions of environment and safety at foodservice operations was carried out. The analysis showed that among the workers many women were irregular employees. For average age, between 40 and 49 was the most frequent, and for work duration, under one year was highest. Both regular employees and irregular employees deemed "enough staff" as the most major factor for good foodservice. The regular employees and irregular employees thought "high indoor temperatures and poor ventilation in the kitchen area" and "bad work cooperation between employees" as the main problems of foodservice operations, respectively. For satisfaction with the efficiency of foodservice production system, irregular employees had higher satisfaction than regular employees. Both regular employees and irregular employees thought "the number of foodservice employees" as the foremost improvement for safety-accident prevention and work-stress improvements. Regular employees, more than irregular employees, thought improvements in foodservice production systems would have a large affect on safety-accident prevention and work-stress improvements of food workers. Both regular employees and irregular employees thought "foodservice employees' safety consciousness" was an important part of safety-accident prevention. Likewise, they responded that "lectures by the person in charge of safety education" was a good methods of safety education, and "once a month" was the best period for safety education. For the difference in perceptions of environment and safety in foodservice systems, regular employees had a higher perception of safety than irregular employees.

In contemporary times, there is an increasing demand for a dedicated healthcare environment, all over the world. The main motivation for this demand is the level of awareness manifested by the users and reflected on their expectations. Therefore new research strategies and design actions are investigated in order to answer to the users' needs and to provide objective design tools for the specialist. This study continues a series of previous developments of the Healthcare Environment Color Index that should be used for public facilities in Korea and abroad. The cross-cultural approach is a new opportunity for exchanging know-how and for testing and calibrating the perception of the users on the color index. The gathering of results was made based on the online survey provided in this phase in English version for the Romanian users. The survey was intended as an objective mean of research and an efficient way of disseminating information on the subject thus contributing to increasing the level of awareness of the users. A total of 86 Romanian and 89 Koreans with valid answers took part in the survey. Comparative visualizations of the results showed significant similarities concerning the patterns of color preferences but also cultural and emotional differences. As a result both categories of users proved to be aware of the relation between healthcare environment color and its effects on health. They also showed a common understanding on the potential of the color index. As a result the most appealing colors to be applied to the healthcare environment were the series G and B, and the most effective ones were proved to be the ranges of high lightness and low saturation but also the medium high lightness and medium saturation. Both the similarities and the differences of choice between Romanians and Koreans show that cultural and emotional differences of color recognition are important and that should be taken into consideration in design, in order to generate an inclusive and efficient healthcare environment.

This study examined the weight control and food habits in 160 obese children and 191 normal-weight children in 4th, 5th and 6th graders of some elementary schools in Gumi city. Regarding the subjects' self-recognition of their body shape, 27.8% of the normal weight group and 92.5% of the obese group acknowledged themselves to be obese. 58.9% of the normal weight group and 61.0% of the obese group were not satisfied with their own body shape and the difference between two groups was very small, 23.6% of the normal weight group and 87.5% of the obese group have tried to reduce weight. The main causative factor of weight gain that children themselves recognized was a sedentary life style. All the students showed a high rate of irregular and unbalanced diet. The obese children showed a significantly higher rate of skipping meals and eating meals faster than the normal weight children. More obese children disliked exercise, and did less excercise than the normal weight children. There was a negative correlation between the obesity index and the food habit score. In other words, they frequently skip a meals, eat in a hurry and dislike vegetables and dairy products. In addition, there was a positive correlation between the student's BMI and the parents' BMI. Overall, many normal weight children showed a high level of self-consciousness of being obese or underweight. Both groups showed a low degree of satisfaction with their own body shape. Therefore education for the distorted perception of body shape is needed because, even normal weight children have tried to reduce their weight. Obese children should be encouraged to exercise, not skip a meals and eat slowly. They also need a systematic education program on weight reduction and weight maintenance. Moreover, education on a healthy diet, healthy food habits, and healthy body shape are necessary for elementary school children.
