본 연구의 목적은 첫째, 프로세스 기획 역량이 신제품 개발 성과에 미치는 영향을 검증하고자 한다. 특히, 프로세스 기획 역량이 개별적인 프로젝트의 성과가 아닌 제품군 전체의 성과에 미치는 영향력을 검증하였다. 둘째, 개발 역량 간 상호작용이 신제품 개발 성과에 미치는 영향을 살펴보았다. 본 연구는 국내 103개 제조기업으로부터 수집한 설문응답 분석에 기초하였다. 제품군 개발은 크게 두 가지 유형의 프로젝트 (플랫폼 및 파생제품 개발)으로 구분된다. 본 연구에서는 두 가지 프로젝트 유형 중, 제품군 성공의 중심적인 역할을 수행하는 플랫폼 제품을 중심으로 분석하였다. 본 연구결과 제품군의 기술적 성과 및 상업적 성과 향상을 위해 우수한 프로세스 기획 역량이 필요함을 보여준다. 또한 기술개발 역량은 기술적 성과에 직접적으로 유효한 영향을 미치지는 않지만, 프로세스 기획 역량과 상호작용을 통해 기술적 성과 향상에 영향을 미치는 것을 확인하였다.

The purpose of this study is to measure the impact of Korean speakers' English stop pronunciation on their general pronunciation proficiency. For these purposes, 20 Korean speakers read English sentences and their pronunciations were rated by native English speakers. The Korean speakers' VOT values of English stops in sentences were then measured and the relation between the VOT values and native speakers' pronunciation rating was compared. Here, the relation between (1) the proficiency score of each speaker and VOT values; and (2) the proficiency score of each sentence and VOT values were analyzed. The results show that there is a relation between the proficiency score of each sentence and VOT values of /t, b, d, g/; and there is a relation between VOT values of /t, b, d, g/ and proficiency scores of each speaker while these is a weak relation between VOT values of /p, k/ and proficiency scores of each speaker.

This study was purposed to discuss an educational concept of listening potential in ESL/EFL contexts as a counterpart of the reading potential concept in L1 contexts. As a preliminary condition for the concept of listening potential, this study investigated a relationship between reading and listening proficiency of ESL/EFL learners, focusing on roles of grammar knowledge in reading and listening comprehension. Reading and listening comprehension and grammar knowledge test scores of 231 Korean college students studying at a university in the U.S. were analyzed for this study. This study found that there was a positive correlation between reading proficiency and listening proficiency of Korean ESL college students. Grammar knowledge played significant roles accounting for reading and listening comprehension. Furthermore, this study found a difference between the reading proficiency and the listening proficiency across the stages of language development. However, results of this study did not empirically verify the concept of listening potential.

A purpose of this study is to investigate the acoustic characteristics of English stress produced by the two groups of South Kyungsang (henceforth, SK) Korean speakers: high-proficiency and low-proficiency with reference to English native speakers. Another purpose is to compare results from the high- and low-proficiency SK Korean subjects with those of the native speakers, and to provide an analytical account of how approximate the high-proficiency SK Korean subjects' production is to the native speakers' and how different the low-proficiency SK Korean subjects' is from the native speakers'. Results indicated that the native speakers' main strategy used in producing stressed syllables was duration while the high-proficiency SK Korean subjects' was predominantly pitch-oriented. The low-proficiency SK Korean subjects' pitch patterns showed regularity, emphasizing the penultimate syllable with pitch. In comparing duration among the three groups, both groups of the SK Korean subjects became more even in their duration values for each syllable as the structure of the word or the sentence became more complex.

Much research attention has been directed to identify how native speakers perceive non-native speakers' oral proficiency. To investigate the generalizability of previous findings, this study examined segmental, phonological, accentual, and temporal correlates of native speakers' evaluation of L2 Korean proficiency produced by learners with various levels and nationalities. Our experiment results show that proficiency ratings by native speakers significantly correlate not only with rate of speech, but also with the segmental accuracies. The influence of segmental errors has the highest correlation with the proficiency of L2 Korean speech. We further verified this finding within substitution, deletion, insertion error rates. Although phonological accuracy was expected to be highly correlated with the proficiency score, it was the least influential measure. Another new finding in this study is that the role of pitch and accent has been underemphasized so far in the non-native Korean speech perception studies. This work will serve as the groundwork for the development of automatic assessment module in Korean CAPT system.

This study aims to analyze the effect of attitudes of Korean residents in Japan towards learning the Korean language and their motivational intensity on their Korean proficiency. Data for this study came from a survey on language use of Korean residents in Japan which was conducted in 2016, and questionnaire items referred to language attitude, language use and the degree of understanding language; language use; language learning and Korean ethnic identity. The main results are as follows. First, there were significant differences in Korean language proficiency depending on age, education levels and generation. Second, the control for socio-demographic characteristics, the influence of attitudes towards Korean language on Korean proficiency was statistically significant. However, Korean proficiency was not significantly influenced by motivational intensity. Lastly, moderated effects of immigrant generation in the relation between Korean language attitudes and Korean proficiency were significant. Therefore, the effect of Korean language attitudes on Korean proficiency was more influential on second and third generation Korean-Japanese learners than first generation Korean-Japanese learners. Based on these results, this study suggests that in order to promote Korean language education for Korean residents in Japan, it is required to build positive attitudes toward Korean language, and to consider immigrant generation as a major factor.

Purpose: This study aims to develop distributable samples that can be used for proficiency testing to verify the ability of the testing laboratory to perform high temperature and low temperature tests. Method: In this study, the temperature-resistance characteristics of the NTC thermistor were used to develop samples. The homogeneity and stability of samples were examined according to the proficiency testing requirements. Results: Thirty samples with homogeneity and stability were developed and used for the proficiency testing. Thus, it was possible to distinguish between the test laboratories that showed satisfactory results and those that did not. Conclusion: It was the first time to develop samples that can be used for proficiency testing in high temperature and low temperature tests. and it was proved that the proficiency test program can be operated using the characteristics of NTC thermistor.

Acute toxicity test with Daphnia magna has a variety of factors such as incubation condition of test species, food quality and proficiency of laboratory workers. Therefore, proper proficiency testing samples were required for evaluating the competence of laboratory workers. This study aims to propose some appropriate proficiency testing samples for laboratory workers of acute toxicity test with Daphnia magna. Proposed four kinds of standard samples (Sample A, B, C, and D) for proficiency testing were selected from reference materials which were recommended from Canada and USA WET(Whole Effluent Toxicity) authorities. Proposed standard samples were tested by trial application of proficiency testing, homogeneity and stability checks using repeatability test. Sample A, C and D were estimated ad the suitable candidates for proficiency test standard samples except for Sample B. In addition, Sample A was proved to be the most suitable sample.

ICAO(International Civil Aviation Organization) established ICAO LPRs(Language Proficiency Requirements) which is an international standard of English for aviation to promote the aviation safety. The Republic of Korea government amended the aviation law on the 8th of November, 2005 and made EPTA(English Proficiency Test for Aviation) as a follow up action. Purpose of this research is analysing the problem of EPTA and improving it. This investigation takes a look at the current ICAO LPRs and compares the difference between EPTA and other global English proficiency requirements for aviation. The result indicated that there is a discordance between the standards of ICAO and EPTA. Also, the global English proficiency reqirements for aviation and EPTA had differences which required improvements. The study suggests to replace more job relevant questions in the EPTA and reform the level system of EPTA.
