Purpose - The purpose of this study is to analyze the past research trends of mountain climbing in order to establish the status as a representative professional Journal of Tourism & Industry Research in Jeju National University. It is expected that it will be able to lay the foundation for the utilization of the subsequent research by examining the applicability of the new research methodology. Research design, data, and methodology - The data to be used in the analysis of this study are the results of a total of 322 journals. In this study, content analysis and meta analysis for semantic network analysis is performed in parallel. NVivo 11 pro is used to clearly identify which of the final classical research articles were extracted and incorporated into existing studies. In addition, KH Coder 3, an open source program, was applied to the study to conduct a meta-analysis on the research subjects. Results - In the research methodology, the proportion of quantitative research is 53.7% (173), which is higher than the qualitative research (143, 45.3%). First, despite the multidisciplinary approach and diversity of research topics, there was a lack of originality and symbolism in the actual research content. Secondly, it has been studied variously in the research subject mainly tourism industry such as tourism, service, industry, marketing, strategy, system, development, performance, relationship, satisfaction. Third, the classification of research is divided into service performance and quality, customer satisfaction , strategy , marketing , and tourism development industry Conclusions - In this study, two future directions are presented as follows. First, we need to establish a foundation for multidisciplinary academic journals through mixing and expanding research themes. It is necessary to establish a foundation to actively reflect the demand for new disciplines by broadly expanding within a wide range of directions without limiting the specific areas of each discipline. Secondly, technological aspects that coexist on the socio-cultural background should not be overlooked either. It is suggested that a special strategy should be prepared to present an insight into the problems of the complex intertwined community and to become a fused - journals centered on tourism.

링정방 공정중의 사절수를 추정하기 위하여 간단한 수학적 모델를 만들었다. 사절현상에 가장 중요한 방사장력, 및 단사강력 만을 고려하여 사절수에 가장 기여도가 큰 요인을 찾아내고 사절율을 이론에 의해 유도하였다. A Study on the end breakages in ring spinning by simple mathematical model has been carried out. The most important factors such as yarn strength, yarn strength variation, spinning tension and spinning tension variation were considered among the factors known as affecting the breakage phenomena. The relative importance of such factors was investigated and the number of end breakages based on the mathematical model was calculated. From the theoretical results, it could be concluded that the value of end breakage rate is obtained and the most important factor contributed to breakages is yarn irregularity.

본 연구는 예비특수교사를 대상으로 AI⋅디지털 역량에 대한 인식을 조사하고 AI⋅디지털 하위역량별 중요도와 실행도를 분석함으로써 우선순위를 도출하는 것을 목적으로 하였다. 연구의 목적을 달성하기 위해 AIEDAP 프로젝트를 통해 개발된 예비⋅현직 교원의 AI⋅디지털 역량체계를 활용하여 95명의 예비특수교사들에게 설문조사를 실시하였다. 자료 분석을 위해 IPA 분석과 Borich 요구도를 산출하였으며, LF 모델 분석을 실시하였다. 연구결과, 첫째, 예비특수교사의 AI⋅디지털 역량에 대한 인식은 초급에서 중급 수준으로 나타났으며, 수업실행 하위영역의 역량에 대한 인식 수준이 다소 낮게 나타났다. 둘째, LF 모델 분석 결과, HH영역에 위치하고 높은 Borich 요구도를 보인 우선 순위군에 해당하는 요구역량은 총 8가지로 나타났다. 셋째, 우선순위가 높은 역량들은 주로 교육실천 영역에 해당했고, 특히 교육맥락분석, 수업 실행역량 영역에서 많이 나타났다. 연구결과의 시사점을 예비특수교사의 AI⋅디지털 역량 수준에 대한 진단, AI⋅디지털 역량 제고를 위한 프로그램의 필요성 및 프로그램 구성 시 고려사항을 중심으로 제시하였다. 연구의 제한점과 함께 추후 연구를 위한 제언이 논의되었다. The purpose of this study was to derive priorities by investigating the awareness of AI⋅digital competencies for pre-service special education teachers and analyzing the importance and performance of each AI⋅digital sub-competence. To achieve the purpose of the study, a survey was conducted on 95 pre-service special education teachers using the AI⋅digital competence system of pre-service and in-service teachers developed through the AIEDAP project. IPA analysis was performed for data analysis, Borich needs analysis was calculated, and LF model analysis was performed. Results were as follows; First, the AI⋅digital competencies of pre-service special education teachers were shown to be at the beginner or intermediate level, and the competencies in the areas of teaching performance were somewhat low. Second, as a result of the LF model analysis, there were 8 required competencies in the highest priority group that were located in the HH quadrant and showed high Borich needs. Third, high-priority competencies mainly corresponded to education practice areas, especially, the areas of education-context analysis and teaching performance. The implications of the research results were discussed focusing on the diagnosis of the AI⋅digital competencies of pre-service special education teachers, the necessity of programs to enhance AI⋅digital competencies, and considerations when constructing programs. The limitations of the study and suggestions for future research were discussed.

Growth and physiological disorders caused by abnormally low temperatures were evaluated in pepper, an important field crop in Korea. In addition, the effects of chemical treatment using glutamine was verified on minimizing the damages by low temperature. The growth of pepper plants in stem length and diameter was suppressed as the temperature decreased from 25℃, and the suppression level was the highest for plants grown for 90 days at 20℃. However, root growth was not affected by the different temperatures. The number of leaf and leaf area decreased at the temperatures below 25C, an optimum temperature for growth. Fresh weight and dry weight decreased for plants grown at 20℃. Pepper fruit yield also decreased by 11% at 20℃ in comparison to 25℃. Falling blossom rate was different depending on the growth temperature, and the rate was 27.2% at 25℃, 35.2% at 22.5℃, and 41.0% at 20℃, indicating that falling blossom rate increased as temperature decreased. Different growth temperatures did not affected on the level of symptom of calcium deficiency and Phytopathora blight. Falling blossom was severe at abnormally low temperature of 20℃, but the treatment of glutamine reduced falling blossom rate and increased the yield by 7.0% as compared to control. The optimum concentration of glutamine treatment was 10 mg/L for yields.

In order to investigate the possibility of improvement of the open end spinning machine which has higher productivity and is more economical than the existing ones, 5 kinds of new open end spinning equipments were designed and operated to produce cotton yarns. The two of those five, enclosed rotor with grooved twister and open rotor with grooved twister, were operated only to produce yarns of Ne 8.5, Ne 4.0 respectively. The quality of both yarns were inferior. The other three types of five, the closed rotor, the closed rotor with radial twister and closed rotor with pinned twister, were operated to produce cotton yarns of Ne 11.0, Ne 11.9 and Ne 10.5 respectively. The quality of produced yarns with these three equipments was fairly good and acceptable.

This study was conducted to examine the effect of LED light quality and supplemental LED light on growth and flowering for potted flowering plant of Kalanchoe. 1. Plant height of Kalanchoe was enhanced under Red, regardless of treatment time. 2. Root length and stem diameter of Kalanchoe were enhanced by Red+Blue. 3. The number of internodes was not influenced by LED light quality. Length of flower stalk of Kalanchoe increased under Red+Blue, but treatment time did not result in statistically significant differences. 4. Leaf area was not influenced by LED light quality in Kalanchoe. 5. The number of flower buds and open flowers was decreased by LED light treatment, but days to flowering was reduced by Red+Blue for 4 hr after sunset in Kalanchoe. 6. Chlorophyll and anthocyanin content was not significantly affected by LED light treatment, but anthocyanin content tended to increase by Blue 4 hr after sunset. 7. Fresh and dry weight did not increased by LED light treatment in Kalanchoe.
