This study applied the DEA model to 29 cultural tourism festivals selected from 2015 to 2017, which are important tourism resources of local governments, to identify efficient festivals and ineffective festivals. In order to identify causes of inefficient festivals and to present improvement plans, we conducted a Returns to Scale Analysis, comparing the actual rating of cultural tourism festivals selected by the Ministry of Culture and Tourism, and analyzed the difference of input factors between two groups of efficient festivals and inefficient festivals. Finally, the purpose of this study was to present the appropriate amount of output factors for the conversion of reference count and cultural tourism festivals evaluated inefficiently into efficient cultural tourism festivals through the lambda (λ) value which is an influence of inefficient cultural tourism festivals. As a result of the technical efficiency analysis using the CCR model, 6 festivals in 2015, 5 festivals in 2017, and 6 festivals in 2017 were analyzed as efficient cultural tourism festivals. In the BCC model, which complemented the shortcomings of the CCR model, 10 festivals in 2015, 11 festivals in 2016, and 10 festivals in 2017 were analyzed, indicating that some festivals were due to scale inefficiency. Among the results of the analysis using CCR and BCC models, only the Damyang Bamboo Festival and the Memorial Chungjang Festival were analyzed as efficient festivals from 2015 to 2017 continuously. As a result of the Return to scale analysis for the inefficient festival, there are 7 festivals in 2015, 4 in 2016, and 4 in 2017 that correspond to IRS. Also there are 16 festivals in 2015, 20 in 2016, and 19 in 2017 that correspond to DRS, indicating that there are more DRS types. Therefore, it is analyzed that many festivals should consider the improvement of the operation method of festivals such as diversification of festival program rather than expansion of input scale. The comparison between the actual rating of cultural tourism festivals selected by the Ministry of Culture and Tourism and the efficiency results of this study shows a significant difference. It is analyzed that this is because of the difference of quantitative analysis by input‧output factors and the criterion for selection of cultural tourism festival which is focused on qualitative criteria. There was no difference in budget, which is an input factor between efficient festivals and inefficient festivals. As a result of the analysis of relative efficiency through the value of lambda(λ), which is the influence of efficient festival on inefficient festival, the most efficient festivals most referenced in inefficient festivals are Jindo Miracle Sea Road Festival, in 2015, 2016, and Jarasum Jazz Festival in 2017. Appropriate calculated values to be converted into efficient festivals using the lambda(λ) value of the reference group are presented in [Appendix 4]. The tier analysis was conducted in order to derive the effective target and practical improvement goals step by step and selectively. In this way, realistic reference target festival that inefficient festival can benchmark was proposed.

한글 입력 방식의 구현을 위한 범용적인 복합 낱자 분석 시스템

김용묵(Yongmook Kim),김국(Kuk Kim) 한국인지과학회 2017 인지과학 Vol.28 No.4

한글 입력 방식은 어떤 형태이건 기본 낱자들에 대한 글쇠배열과 결합 규칙이라는 두 요소를 반드시 가진다. 그런데 그 규칙을 토대로 입력 방식을 실제로 구현해 보면, 기본 낱자가 여럿 모인 복합 낱자를 입력할 때 모호성이 존재하거나 다음 글자의 연속 입력이 되지 않는 식의 문제가 발생할 수 있다. 한글은 모아쓰기라는 특성으로 인해 낱자 경계와 글자 경계라는 보이지 않는 정보가 입력 과정에서 추가로 고려되어야 하기 때문이다. 초성과 종성을 문맥에 따라 구분해야 하는 두벌식, 글쇠가 매우 적은 모바일 환경, 수십 종류의 낱자들을 조합해야 하는 옛한글이라는 조건이 더해지면 입력 방식을 기술하고 분석하는 난이도가 더욱 높아진다. 본 논문에서는 한글 입력 방식에서 쓰이는 낱자의 결합 규칙을 대결합과 소결합으로 구분해서 기술하는 체계를 제안하며, 이를 토대로 어떤 입력 방식이 주어졌을 때 복합 낱자를 입력하는 세부 규칙을 생성하고 예상되는 문제점을 자동으로 분석해 주는 도구 프로그램을 소개하였다. 그리고 모바일용 삼성 천지인과 KT나랏글 한글 입력 방식을 실제로 분석한 결과를 제시하였다. A Hangul input method consists of two core components: key layout for primitive units (Natja), and binding rules to form more complex, composite units from primitive ones. However, careless design and implementation of an input method may result in ambiguity and inability of contiguous typing, when it comes to handle composite Hangul units. This is due to the collective nature of Hangul, namely, existence of implicit boundaries between units and syllables. This issue gets more challenging for the context-dependent 2-beolsik method, mobile environment having significantly fewer keys, and yet addition of the support for Old Hangul. For the sake of the management of complexity, we devised a system in which the binding rule is divided into two layers rather than one. Based on this concept, we implemented a tool program that, given the primitive units and their binding rules, generates input details of every composite unit and detects any potential ambiguity and conflicts. We presented the actual analysis result for Samsung Cheonji-in and KT Naratgeul, two of the most popular mobile Hangul input methods used in Korea.

목 적 : Kikuchi 병은 고열을 동반한 양성 림프절 비대를 특징으로 하는 아급성 괴사성 림프절염이다. 주로 젊은 여성에게 발생하며 소아에 있어 드물게 보고되고 있다. 병인으로는 바이러스와 연관성, 자가 면역기전 등이 제시되고 있으나 정확히 밝혀지지 않은 상태이다. 최근 저자들은 소아에서 발생한 괴사성 림프절염 5례를 경험하였기에 소아에 있어 Kikuchi 병의 임상적 고찰을 하였다. 방 법 : 2001년 1월부터 2006년 6월까지 경희대학교 소아과에 Kikuchi 병으로 진단 받은 환아 5명을 의무기록을 통해 발생 연령, 성별비, 계절별 발생빈도, 임상증상, 과거력, 검사 소견, 림프절의 발생 부위 및 크기, 방사선학적 소견 등을 조사하였다. 결 과 : 남아가 2명, 여아가 3명이었으며, 평균 연령은 9년 9개월(8년 2개월-12년 6개월)이었다. 주된 증상은 지속되는 발열과 림프선 비대로 병원을 방문하였다. 모든 환자는 항생제 치료를 받았으며, 2명의 환자에게서 발진이 발생하였다. 1례에서 초음파 검사상 Kikuchi 병이 의심되는 괴사성 변화가 관찰되었다. 3례에서 추가적으로 컴퓨터 단층촬영을 실시하였다. 입원 후 절제 생검할 때까지 소요된 시간은 10.2일(7-15일)이었다. 5례 모두 림프절 절제 생검 후 조직 검사상 괴사성 림프절염으로 확진하였다. 결 론 : Kikuchi 병은 진단 전에 불필요한 검사와 항생제 치료를 하며 이로 인해 입원 기간도 길어진다. 이에 저자들은 소아에 있어 Kikuchi 병의 임상 양상을 고찰하였다. Purpose : Kikuchi disease is a subacute necrotizing lymphadenitis characterized by fever, cervical lymphadenopathy and benign self-limiting course in young women especially, but rare in children. Their etiopathology is still unknown, but involved viruses and autoimmune mechanism were proposed. We investigated the clinical and laboratory characteristics of Kikuchi disease in children. Methods : Five patients were diagnosed of Kikuchi disease from January 2001 to June 2006 in Kyunghee University Hospital. We reviewed their medical records retrospectively and analyzed clinical and laboratory findings. Results : The mean age of 5 patients (male to female ratio; 2:3) was 9 yr 9 mon(range: 8 yr 2 mon-12 yr 6 mon). The chief complaints were sustained fever and cervical lymph node that was unilateral, tender and swollen. All patients were treated with antibiotics before diagnosis was made, and rash developed in 2 patients. One patient showed necrotic change in ultrasound with which we suspected Kikuchi disease. Three patients were examined by CT scan additionally. The interval between admission and cervical lymph node excisional biopsy ranged from 6 days to 15 days, and mean period was 9.6 days. All pathological findings were compatible to necrotizing lymphandenitis. Conclusion : Unnecessary laboratory and imaging studies, and treatment with antibiotics tend to be done before making diagnosis, and that caused prolonged hospitalization. Therefore we studied the clinical and laboratory characteristics of Kikuchi disease in children.
