Language learners’ achievement goal orientation and self-efficacy have been one of the important factors determining their persistence and efforts in their language learning. This study analyzes a total of 1091 Korean language learners in order to examine whether their ages, cultural background, and their mastery in Korean language affect their achievement goal orientation and self-efficacy. With respect to the cultural background, the learners from Japan turn out to show a lower degree of achievement goal orientation and self-efficacy. And the learners at the introductory level show a significantly higher degree of achievement goal orientation and self-efficacy than the learners at the intermediate and the advanced level, respectively. In examining the effect of achievement goal orientation on self-efficacy, it is found that performance-approach and mastery-approach have a positive effect on self-efficacy whereas performance-avoidance and mastery-avoidance have a negative effect. Specifically, the orientation toward mastery-approach explains a significantly larger portion of the change in self-efficacy. In order for Korean language learners to enlarge their self-efficacy, therefore, it seems necessary to create the classroom environment where they can facilitate their orientation toward their mastery-approach.

Demand for Korean language instructors is increasing as the number of Korean language learners increases. While such demand is even higher outside Korea, securing a sufficient number of instructors who majored in Korean education or possess Korean instructor license is more difficult overseas than in Korea. In many occasions of overseas Korean education, learners and instructors share the same native language. In such cases, instructors from the same country and culture can enhance learners’ satisfaction than do instructors from Korea. However, from a non-Korean speaker’s point, obtaining a Korean instructor license is difficult. Reflecting this fact, it is necessary to explore ways in which we can train Korean instructors outside Korea. In this study, we suggest directions for developing specialized foreign Korean language instructor training programs and how to manage them based on actual cases.

삼세기 (Hemitripterus villosus)는 새로운 양식 어종으로 대두되고 있으나, 자원량이 감소하고 있으며, 양식 어종에서 지속적인 문제로 나타나는 골격 기형에 대해 삼세기의 정상적인 골격발달 기준을 제시하고자 한다. 이 연구에 사용된 시료는 어획된 어미로부터 채란된 수정란을 부화시킨 자치어를 포르말린액에 고정한 뒤 Kawamura and Hosoya (1991) 염색법에 따라 염색하여 골격발달을 관찰하였다. 부화 직후 평균전장 13.65±0.71mm(n=5) 일 때 부설골과 주상악골, 전상악골, 치골이 골화되기 시작하였고, 부화 후 65일째 평균전장 21.24±0.50mm(n=5) 일 때 사골과 안상골이 골화하면서 두부가 완성되었다. 견대부는 부화 7일째 평균전장 14.61±0.52 mm (n=5) 일 때 쇄골, 주새개골, 관절골이 골화하기 시작하였으며, 부화 44일째 평균전장 18.15±0.61mm(n=5) 일 때, 4개의 사출골이 골화되어 견대부가 완성되었다. 부화 10일째 평균 전장 14.80±0.65mm(n=5) 일 때 척추골의 골화가 시작되었으며, 부화 후 54일째 평균전장 18.67±0.54 mm (n=5) 일 때 척추골 추체 39개가 골화하여, 부화 60일째 평균전장 20.25±0.45mm(n=5) 일 때 척추골의 골격이 완성되었다. 이 연구는 삼세기 자치어의 골격발달에 대한 것으로 삼세기의 자치어 골격 기형의 기준과 기초자료 연구에 사용될 것이다. Hemitripterus villosus, a promising aquaculture fish species, is facing declining stocks. This study aims to provide normative standards for skeletal development to address persistent skeletal deformities in farmed fish. Specimens utilized in the study underwent artificial insemination with captured fish, and the resulting larvae and fry were preserved in a formalin solution. The skeletal ossification process commenced immediately after hatching, affecting the parasphenoid, premaxillary, maxillary, and dentary structures at an average total length of 13.65±0.71 mm (n=5). By sixty-five days post-hatching, ossification extended to the ethmoid and supraorbital, completing the head’s development at an average total length of 21.24±0.50 mm (n=5). Clavicle ossification occurred at seven days post-hatching, corresponding to an average total length of 14.61±0.52 mm (n=5). At forty-four days post-hatching, the ossification of 4 actinosts took place, completing the shoulder girdle, with an average total length of 18.15±0.61 mm (n=5). Vertebral ossification initiated at ten days post-hatching, with an average total length of 14.80±0.65 mm (n=5). By fifty-four days post-hatching, 39 vertebral columns were ossified, reaching an average total length of 18.67±0.54 mm (n=5). Vertebral development was complete at sixty days post-hatching, with an average total length of 20.25±0.45 mm (n=5). This study sheds light on the skeletal development of H. villosus, providing valuable standards and fundamental data for understanding skeletal deformities in this species.

This study examines pronunciation error types of KFL(Korean as a Foreign Language) learners and suggests an effective teaching method base on the examination First, for this study the pronunciation data of native speakers in English, Japanese, Chinese and Russian are collected, and the error types are analyzed. The types of error are various depending on the individual, but error types and causes can be categorized into five case. The first case is when the speaker does not clearly know the conditions for vowel differentiation and does not follow the rules of distinctive features of vowels. The second is when the speaker does not know the conditions for consonant differentiation and does not follow the rules of distinctive features of consonants. The third case is on the errors on the principles of syllable structure. The fourth case is on the numbers of syllables. The fifth is when the speaker does not follow the rules of phoneme conversion. There are cases of inaccuracy in individual phonemes depending on the native language of the speaker, but these cases do not affect communication. The cases of sound confusion within the Korean phoneme system affect communication. Therefore, it is important for the speakers to be aware of the distinctive features of Korean vowels and consonants and to produce the features.
바이오 가스 생산을 위한 미세조류 바이오매스로서의 Dunaliella salina

본 연구는 혐기성 소화조에서 바이오 가스 생산을 위한 바이오매스 자원으로서 Chlorella vulagaris와 Dunaliella salina의 이용능력을 확인하였다. 세포벽의 구조에 따라 전처리 후 용해성 물질의 수율이 영향을 받았는데, 이는 D. salina가 바이오 가스 생산 측면에서 C. vulgaris보다 좋은 후보라는 것을 보여준다. 혐기성 소화조에서 얻은 접종원으로부터 전처리하거나 전처리하지 않은 D. salina를 기질로서 메탄가스를 생산하는데 이용하였을 때 메탄 수율 측면에서 큰 차이가 없었다. 그러므로 D. salina는 높은 바이오매스 생산성, 단순한 전처리 필요성, 쉬운 바이오 가스전환 때문에 바이오 가스 생산을 위한 적합한 해조류 바이오매스이다. In this study, the ability of Chlorella vulgaris and Dunaliella salina to use biomass resources for anaerobic digestive biogas production was examined. The differences in cell wall structure pretreatments affecting the yield of soluble products showed that D. salina is a better candidate for biogas production than C. vulgaris. There was no significant difference between pretreated and non-pretreated D. salina in terms of methane production yield by inocula obtained from anaerobic digestion systems. Therefore, D. salina is a suitable algal biomass for biogas production due to its high biomass productivity, simple pretreatment needs, and easy con-version to biogas.
