The purpose of this study was to verify the effectiveness of the computerized cognitive rehabilitation program in which areas and to suggest effective ways to utilize the program in the future, being conducted for 20 college students. We lasted this study from May 3 to 23, 2021. As a result of analyzing the groups using the Computer-based Cognitive Rehabilitation Program (CoTras), in terms of the difference in accuracy for the case of visual perception group B was statistically significantly improved than group C(p<0.05). In the case of attention, memory, and orientation, there was no significant difference between groups(p>0.05). In the case of reaction time difference, there was no significant difference between groups in visual perception, concentration, memory, and orientation(p>0.05). And in order to improve attention and visual perception, it is recommended to conduct the program three times with a duration of 20 minutes, and in order to improve orientation and memory, it can be said that it is helpful to conduct one experiment for at least 30 minutes rather than conducting short and frequent experiments. Through this study, we found that it is effective to apply different times according to each area to improve cognitive function. In other words, depending on the purpose of which cognitive function is to be improved, the duration of the program should be applied differently.

This study was conducted to investigate the difference of perception about nutritional problems and food intakes and nutrition knowledge score and realities of nutrition education between parents and preschool teachers. This research can be summarized as follows: there was the statistical difference of perception (${\chi}^2$= 52.451, p = 0.000) about nutritional problem of preschoolers between parents and preschool teachers. Parents (56.4%) and teachers (58.5%) identified eating only what they want as the most common nutritional problem of children, but they had different perception about the other problems. To parents, "No nutritional problem" (16.3%) is the second and "Overindulgence of processed food" (11.1%) is the third problem of preschoolers. To teachers, "Overindulgence of processed food" (23.8%) is the second and "Obesity" (14.3%) is the third problem. The perception on food intakes of preschoolers was statistically different in meats (${\chi}^2$= 8.892, p = 0.030), fish (${\chi}^2$= 32.241, p = 0.000), beans (${\chi}^2$= 14.770, p = 0.005), vegetables (${\chi}^2$= 12.706, p = 0.013), fruits (${\chi}^2$= 14.438, p = 0.006) and milk & dairy products (${\chi}^2$= 28.591, p = 0.000) between parents and preschool teachers. However, nutritional knowledge was not different between parents and preschool teachers. While 96.6% of preschool teachers felt that it was necessary to educate preschoolers, only 41.5% of them said that they fulfilled nutrition education, showing that nutrition education was not adequately carried out on the spot. Therefore providing basic materials through which nutritional management guidance and proper nutrition education for preschoolers can be carried out by investigating and analyzing knowledge on their nutrition and meal guidance activities for preschooler teachers and parents.

Objectives: The purpose of this study is to obtain basic data on the development of a risk communication model through an investigation of risk perception for radon and identify effective risk communication channels. Methods: A questionnaire was used to evaluate differences in perception level according to respective communication channels. A chi-squared test was used to analyze the difference in pre- and post-risk communication by communication channel. One-way ANOVA was used to analyze the difference in the radon risk perception rate for each communication channel. Results: All of the communication channels resulted in increased radon risk perception, but there was no statistical difference between them in terms of perception (p>0.05). However, based on previous findings that it is effective to use a multi-channel approach, it is considered that communication channels based on duplicate avenues is most appropriate. Conclusions: It is expected that this study will be used as basic data to better understand the formation of public opinion about radon risk and to understand the social reaction to each risk factor.

In Korean, wh-question and indefinite yes-no questions have the same morphemic and syntactic structure. In speech, however, these two types of questions are distinguished by a prosodic difference. In this study, we examined if Chinese Korean leaners can distinguish between these two types of questions in production and if they can correctly perceive the different meaning of a question based on the prosodic information. For this purpose, we analysed two types of interrogative sentences produced by 5 native speakers and 15 Chinese Korean language leaners. The results show that the 5 Korean native speakers produce two types of questions by a salient prosodic difference, i.e., difference of prosodic structure, different pitch range of wh-phrase and indefinite phrase, and different boundary tone. However, for the 15 Chinese speakers, the two types of questions were not distinguished by the same prosodic features but in the perception analysis they were able to distinguish between the two types of questions easily.

Exports play an important role in Korea's economy and industry. Korea's share in world trade is also increasing. Governments and trade organizations are making great efforts to promote exports. However, since SMEs lack resources of enterprises, SMEs have a lot of difficulties in increasing exports compared to large enterprises. For this reason, in this study, we analyzed the difference of perception of export difficulties according to characteristics of small and medium export companies. As a result, four factors such as overseas market information, price and cost, competitiveness and regulation of importing country were derived. In addition, we investigated the differences in recognition of export difficulties by the stage of growth of company, period of export, products exported, export department, size of company. There was a significant difference in recognition. Especially, The companies which are the early stages of growth, short export period, finished product, the smaller the size of exports companies are more difficult in export difficulties.

전체 공사 기간의 약 25%를 차지하고 있는 거푸집 공사는 최근 5년간 사망자 수가 크게 줄어들지 않고 계속 발생하고 있으며 그중 붕괴사고가 가장 많은 비율을 차지하고 있다. 따라서 본 연구에서는 거푸집 붕괴사고에 관하여 위험도 및 안전관리 수준에 대한 설문조사를 통해 관리자와 작업자 간에 인식 차이를 비교 분석하고자 한다. 안전관리자, 현장작업자, 현장관리자 3개의 집단으로 구분하여 설문조사를 시행하였으며, 설문결과는 SPSS 프로그램을 활용한 독립표본 T-검정(Independent-Sample T-Test)을 시행하였다. 그 결과 관리자 간에는 인식의 차이가 거의 없는 반면, 관리자와 작업자 간에는 유의미한 인식 차이가 발생하였다. 더불어 관리도 측면에서 관리자와 작업자의 많은 인식 차이가 발생했으며 이 부분은 위험한 재해요인을 관리 및 감독하는 관리자와 직접 현장에서 작업을 진행하는 작업자 간의 입장차이를 극명하게 보여준다. 이러한 인식 차이가 재해를 줄이지 못하고 있는 요인이 될 수 있다고 사료된다. 따라서 이 연구를 바탕으로 좀 더 발전된 연구를 통하여 관리자와 근로자 간 인식의 차이를 줄여 재해에 관한 연구 시 기초자료로 활용될 수 있을 것으로 판단된다.

The purpose of this study was to examine interactive effect of wedding makeup, head dress, and perceiver's culture on bride's image perception. Image analysis was carried out by 10 photos which was designed for brides in their twenties with different makeup and head dress. Subjects were female university students in Seoul, Korea and 100 black female university students in Delaware, U.S. The result of study was as follows. Image perception by bride's makeup and head dress was classified as five dimensions: 'distinctive', 'tidy', 'elegant', 'soft', and 'beautiful'. There was a significant difference in image perception from culture and head dress. The result of interactive effect due to culture and makeup showed that Korean students perceived pink makeup as close to more elegant image, and American students felt orange makeup. We can know through above contents that there was significant difference in image perception by makeup and head dress between Korean and American students. Also, American students in general evaluated the photos (stimulus) presented positively compared to Korean students. This can be interpreted as a meaning that the degree to perceive each photos of American students was lower than Korean students.
