Phonological awareness is a metalinguistic awareness ability of phonology and is known to predict language skills, such as reading and vocabulary skills. The purpose of this study was to investigate the relationship between phonological awareness, phonological processing, and language skills in 4- to 6-years-old typically developing (TD) children and children with language delay (LD). A total of 32 children (TD=18, LD=15) participated in this study. They performed a phonological awareness task consisting of counting, deletion, and discrimination at syllable level. Nonword Repetition, Digit Backward, Receptive & Expressive Vocabulary Test, and Grammaticality Judgment Task were performed to analyze the correlation between phonological awareness, phonological processing, and language ability. A multiple stepwise regression analysis was performed to examine the phonological awareness subtasks that predict language ability. In the TD group, the syllable categorization task significantly predicted the receptive vocabulary and the performance of the Grammaticality Judgment Task. The LD group showed that the syllable counting task significantly predicted the receptive vocabulary, the expressive vocabulary, and the performance of the Grammaticality Judgment Task. The results showed that the phonological awareness performance was significantly different between the two groups. Further, correlation analysis and regression analysis showed different results for each group. The result of the phonological awareness performance predicted the language ability of each group significantly, suggesting the importance of the meta-linguistic awareness ability of phonology.

The present research studied the effectiveness of specific strategy training in memory awareness on children's memory performance. The subjects were 60 children, 30 six-year-olds and 30 eight-year-olds. Free recall scores and use of a rehearsal strategy (exposure durations) based on Belmont & Butterfield (1971) were used to measure children's performance in three memory tasks. All subjects were randomly assigned to one of three experimental groups: the control group with no training, the chunking and rehearsal strategy training group, and the chunking and rehearsal strategy training combined with memory awareness strategy. The data were analyzed with two-way ANOVA, three-way ANOVA with repeated measures, and Student-Newman-Keuls post hoc test. There were significant differences among the three groups both in the free recall score and in the use of the rehearsal strategy. The mnemonic strategic training with memory awareness strategy was the most effective on both free recall and use of rehearsal strategy. The effects of the mnemonic strategy training with memory awareness strategy were more effective for the 8-year-olds than the 6-year-olds.

본 연구는 휴대용 게임기에서 가상현실(Virtual Reality)을 구현한 비행기 시뮬레이션 게임을 대상으로 상황인식(Situation Awareness), 수행도(Performance), 현실감(Presence)을 측정하여 세 측정 지표의 상관관계를 분석하였다. 상황인식 측정은 SAGAT (Situation Awareness Global Assessment Technique)을 이용하였고, 수행도는 분당 격추 시킨 적기 수를 기준으로 측정하였다. 현실감은 Presence Questionnaire (Version 3.0) 기법을 통해 측정하였다. 실험 결과 상황인식 2 단계와 3 단계의 능력이 좋을수록 현실감이 증가하는 경향을 보여 상황인식 능력과 현실감에 밀접한 연관이 있다는 기존 연구와 동일한 결과가 휴대용 게임기에서도 일어남을 밝혀냈다. 또한 상황인식 2 단계와 3 단계의 능력이 증가할수록 수행도도 같이 증가하는 경향이 있어 좋은 상황인식 능력이 높은 수행도를 가질 확률을 증가시킨다는 기존의 연구 결과를 뒷받침할 수 있었다. 현실감과 수행도의 관계는 본 실험 결과에서 서로 연관이 있는지 결정하기 어려웠다.

The purpose of this study was to investigate the foodservice employees' awareness and performance in sanitation and customers' satisfaction with sanitation in large sized restaurants in Korea. Sanitation inspections were carried out in 200 large Korean, Western, Chinese, and Japanese style restaurants, and in buffet-style restaurants in Daegu and Gyeongbuk province. Foodservice employees' awareness of sanitation and customers' satisfaction with sanitation were investigated by interviewing 317 foodservice employees and 205 customers. Results of the inspection of restaurants showed low performance in food handling, employees' hygiene (hygienic) practices, and in cleaning food processing equipment. Scores of the foodservice employees' awareness in Chinese style restaurants were significantly lower than scores of workers in western restaurants. Foodservice employees had low awareness of sanitation procedures used for food storage and cleaning of equipment in Korean, Chinese, and Japanese style restaurants. Foodservice employees had low awareness of equipment cleaning, inspection and food distribution in western style restaurants and of equipment cleaning and food handling in buffet-style restaurants. Foodservice employees at all restaurants had the lowest performance in terms of HACCP. This shows that HACCP application and recording have not yet been properly carried out at restaurants in Korea. Foodservice employees had low performance scores in food handling, vegetable disinfection and disinfection after hand washing. Research on customers' satisfaction with sanitation revealed a low rating of kitchens and foodservice employees at all restaurants. Customers had low satisfaction with servers and kitchen environments in Korean style restaurants with food, tableware, utensils and servers in western style restaurants; with food and kitchen environments in Chinese style restaurants with servers, tableware, and utensils in Japanese style restaurants and with kitchen environments and servers in buffet-style restaurants. Therefore, cleanliness of kitchen facilities and equipment, and hygienic food handling procedures by workers in restaurants are urgently needed.

Objectives : The purpose of this study was to examine the job awareness of dental hygiene students about a dental hygienist, what duties they wanted to do as dental hygienists, their awareness of college courses related to the job performance of dental hygienists and whether they viewed the courses as what's most widely utilized for the clinical job performance of dental hygienists. It's ultimately meant to help provide good education for dental hygiene students to have the right understanding of dental hygienists and bolster their professionalism. Methods : The subjects in this study were 301 dental hygiene students in four different colleges located in the metropolitan area. A survey was conducted to find out their satisfaction level with the department of dental hygiene, personal characteristics, awareness of college courses and awareness of the duties of dental hygienists. Results : The group of students who deemed the life span of the dental hygienist occupation to be long put more significance on the college courses that should focus on job performance. As for the relationship between their personal characteristics and awareness of the college courses, their satisfaction or dissatisfaction with the department and their ideas on the life span of the occupation made significant differences to that. The group of students who considered the life span of the occupation to be longer thought that the college courses would be more linked to the duties of dental hygienists and their job performance and should be given more weight, and there were significant differences among them in their view of the life span of the occupation and awareness of the college courses that should be given more weight(p<.05). Their view of how much the college courses would be linked to the duties of dental hygienists had a statistically significant correlation to that of the college courses that should focus on the clinical job performance of dental hygienists. Conclusions : The above-mentioned findings suggest that as part of the regular curriculum, the kind of education that aims at boosting the professionalism and job performance of dental hygienists as experts should be provided for dental hygiene students to build the right values as professional dental hygienists.

Objectives: The purpose of the study is to investigate the relationship between noise awareness, hearing ability, and dental hygiene performance in dental hygienists. Methods: The subjects were 234 dental hygienists in Seoul, Gyeonggi-do, and Incheon. The questionnaire consisted of 3 questions of general characteristics of the subjects, 1 question of noise awareness, 3 questions of hearing ability, 5 questions of dental hygiene performance, 1 question of noise reduction necessity, and 2 questions of noise control. Noise awareness, dental hygiene performance, and noise reduction necessity were measured by Likert 5 scale. Cronbach's alpha was 0.825 in dental hygiene performance reliability. Results: There was a significant difference in noise recognition by age(p<0.01) and working career(p<0.05). Those who pumped up the higher TV volume accounted for 31.6% and 3.0% had hearing impairment in the regular health checkup. 3.4% of the respondents complained of hearing loss, ear fluid, and equilibrium problem diagnosed by the doctors. The relationship between the type of workplace environment and task performance showed a significant difference. Those who work in the dental hospitals had high score of 3.43, while those who work in dental clinics had 3.20(p<0.05). The increased level of noise recognition affected the task performance and it is necessary to reduce the noise level. More try must be focused on the noise exposure prevention. Conclusions: In order to reduce the problems due to noise and improve their quality of life, it is necessary to change the noise recognition in the work place.

This study is the analysis of actual proof about how the CEO's values system affects the organizational performance. To this end, we analyzed the content of forty different actual CEOs' values system through in-depth interviews. In addition, we verify the impact of the CEO's values system on organizational performances depending on the employee's awareness and sympathy. The organizational performance is analyzed in two different areas, social and financial performance, and significant results are obtained in both areas. In particular, we interview the CEOs directly, which is usually difficult to access, to analyze the values system and study the employee's awareness and sympathy for the values system. The Study puts emphasis on the importance of the process of achieving the employee's awareness and sympathy, rather than the values system contents itself. And it is necessary for verifying through much more company samples from further study.
