The purposes of this study were to identify customer expectation, perception and satisfaction of foodservice quality to analyze the influencing factors on foodservice quality and finally to provide basic information for the improvement of foodservice quality. A survey of 4 factory foodservices was undertaken and detailed information was collected from 675 respondents. Statistical data analysis was completed using the SPSS package program for descriptive analysis, t-test and one-way ANOVA. Male had higher scores than female in perceptions of foods and services, and the differences were statistically significant. As analysis of expectation, perception and satisfaction result of age, expectation and perception were statistically significant, and mostly expectation and perception increased according as age increased. Expectation and perception showed statistical differences by marital status. Married people had higher scores in expectation and perception of food and service than single. According to family type, respondents living alone showed lower scores in expectation and perception of food and service than those living with family or relatives. Conversely, living alone had high expectation on service. As analysis of work type, office workers showed higher scores of service expectation, food and service perception than production workers. As education level increased, food and service expectation and perception increased mostly. As analysis of work post, food and service expectation and perception increased as work post raised. Meanwhile, married people had higher scores in service quality of satisfaction than single. Result of the study can be summarized as follows the analysis of expectation, perception and satisfaction of foodservice quality, the Quadrant of food and service quality expectation and perception according to demographic variables. Expectation, perception and satisfaction scores of foodservice attributes according to work type. The distribution of attributes with satisfyingly significant difference in grid.

The purpose of this study was to explore nutrition teachers/dietitians' perception towards production management practices as well as the importance & performance of nutrient preservation during production by school foodservices. A total of 120 school nutrition teachers/dietitians in the Daegu area participated in this study. The data were analyzed by descriptive analysis, t-test, and ANOVA using SPSS/Windows (ver 17.0). A questionnaire consisted of three dimensions with 66 items concerning the general characteristics of schools and respondents, production management practices, and perceived importance and performance of nutrient preservation. Exactly 79.2% of dietitians responded that scheduling of production management is necessary, and 52.5% of respondents perceived that their knowledge for nutrient preservation is of normal/average level. Thirty-eight percent of respondents did not establish scheduling of production management; according to them, cooking stage has priority over other stages of nutrient preservation. Perceived importance score was higher than perceived performance score in all stages of production management. The difference between perceived importance and performance in the production scheduling stage was found to be statistically significant. The results indicate that nutrition control point should be established and managed to prevent nutrient loss in all production stages. Further, dietitians who do not take measures to reduce nutrient loss should be carefully educated on the importance of nutrient control and be motivated to follow guidelines on nutrient preservation.

Korean has two types of voiceless alveolar fricatives: a non-tense fricative /$S^{h}$ and a tense fricative /s'/. Twenty native speakers of Korean produced five pairs of isolated words containing word initial $S^{h}V$ and /s'V/ sequences where V was any one of five (/a, e, i, o, u/) of Korean vowels. Acoustic measures such as duration, fricative noise prominent frequency, energy change of following vowel, and fundamental frequency at vowel onset were examined. Results showed that among the parameters, aspiration noise duration of /s'/ in mid and low vowel contexts was less than 21 ms. In a perception experiment, where only the aspiration noise interval of the /$S^{h}$/ tokens was incrementally reduced, some listeners shifted perception from /$S^{h}$/ to /s'/.

한국어에서는 모음사이에서 겹자음이 나타날 수 있으나 영어에서는 이것이 불가능하므로 영어를 배우는 한국 학생들이 $su\underline{mm}er$와 같이 겹자음 철자를 포함하는 단어들을 발음할 때 철자의 겹자음을 모두 발음하는 오류를 흔히 범한다. 따라서 본 파일럿 연구에서는 한국 학생들이 영어 겹자음 철자를 어떻게 발음하고 인지하는지 살펴보기 위해서 영어 겹자음과 단자음의 (유사) 최소변별쌍으로 구성된 36개의 실제어를 20명의 대학생이 듣고 발음하는 인지와 발화 실험을 실행하였다. 실험 결과 한국 학생들은 철자의 영향으로 영어 단자음 철자 단어를 발음할 때보다 겹자음 철자 단어를 발음할 때 이중으로 길게 발음하는 오류를 더 흔히 범해서 겹자음 철자 단어의 정확율보다 단자음의 정확율이 크게 높았으며, 인지의 경우에도 마찬가지로 단자음 철자 단어의 인지 정확율이 겹자음 철자보다 확연하게 높았다. 덧붙여, 한국 학생들의 영어 유성 파열음의 발화 오류율이 낮은 이유를 한국어 음운 체계의 전이로 설명하였다. 끝으로, 한국학생들의 발화를 스펙트로그램을 통해서 분석함으로써 영어 단자음 철자보다는 겹자음 철자에서 더 많은 발화오류를 일으키는 것도 보여주었고 또한 교육적인 함축점도 제안하였다.

In the early 2020, COVID-19 changed the traditional way of teaching and learning. This paper aimed to explore the impact of college students' perception of course quality on their online learning satisfaction. A total of 4,812 valid samples were extracted, and the difference analysis and hierarchical regression analysis were used to make an empirical analysis of college students' online learning satisfaction. The research results were as follows. Firstly, there was no difference in online learning satisfaction among students by gender and grade. Secondly, learning assessment, course materials, course activities and learner interaction, and course production had a significant positive impact on online learning satisfaction. Course overview and course objectives had an insignificant correlation with online learning satisfaction. Thirdly, the total effect of online learning satisfaction was as follows. Course production had the greatest effect, followed by course activities and student-student interactions, followed by course materials. It was the learning evaluation that showed the least effect. This study can provide empirical reference for college teachers on how to continuously improve online teaching and increase students' satisfaction with online learning.

This study suggests a process design using cognitive processes. Job characteristic model for job design and recent cognitive engineering studies for process design are reviewed briefly. By using these concepts, the lean production system is re-interpreted in terms of cognitive engineering and the latent dimensions of the lean production system are revealed as the application of cognitive engineering principles. An integrated process design framework for cognitive manufacturing system using job characteristic model is suggested for the effective design of manufacturing system. Propositions for empirical analysis of this model are also analyzed through a questionnaire survey. Propositions are (1) experiential cognition and motivation potential affect the ability, role perception, and need for achievement of the operator in the manufacturing system, (2) the ability, role perception, and need for achievement of the operator affect the job performance. Both propositions are supported by correlation analysis and path analysis.

This paper discusses some current issues regarding how prosodic structure is manifested in fine-grained phonetic details, how prosodically-conditioned articulatory variation is explained in terms of speech dynamics, and how such phonetic manifestation of prosodic structure may be exploited in spoken word recognition. Prosodic structure is phonetically manifested in prosodically important landmark locations such as prosodic domain-final position, domain-initial position and stressed/accented syllables. It will be discussed how each of the prosodic landmarks engenders particular phonetic patterns, ow articulatory variation in such locations are dynamically accounted for, and how prosodically-driven fine-grained phonetic detail is exploited by listeners in speech comprehension.

The present study investigated some perceptual phonetic attributes of two Korean stop types, aspirated and lax, in medial position of an accentual phrase. The intonational pattern across syllables (Jun, 1993) is argued to depend on the type of stop (aspirated vs. lax) only in the initial position of an accentual phrase. In Kang & Dilley (2007), we showed that significant differences between aspirated and lax stops in medial position of an accentual phrase exist in closure duration, voice-onset time, and fundamental frequency (F0) values for post-stop vowels. In the present perception experiment, we investigated whether these phonetic attributes contribute to the perception of these two types of stops: The closure durations and/or F0's of post-stop vowels on accentual-phrase medial words were altered and twenty native Korean speakers then judged these words as beginning with an aspirated or lax stop. Both closure duration and F0 significantly affected judgments of stop identity. These results indicate that a wider range of acoustic cues that distinguish aspirated and lax Korean stops in production also plays a role in perception. To account for these results we suggest some phonetic and phonological models of consonant-tone interactions for Korean.
