For a quick and easy way of writing Hangul in hand-held devices, we analyzed the combination rules of Hangul alphabets that we constructed a small set of Hangul alphabets that combines a whole set of Hangul alphabets. Hangul consonants are generated from base set of consonants with function keys and vowels are constructed from eight base set of vowels by combination rules and stroke-adding rules. Especially, we adopted an easy error-correction method to resolve the inconvenience of using a delete key for vowel harmony errors. Futhermore, we diversified the input method of diphthongs for user-friendliness by minimizing the efforts of teaming vowel combination rules. We compared our method with previous methods of 'Chon-Ji-In' and 'Na-Rat-Keul' that the proposed method is better than the previous methods in input speed and error correction functionality.

본 연구의 목적은 우리나라에서 발행가격 결정을 발행회사와 주간사회사에게 완전 자율화 하였음에도 불구하고 우리나라의 최초공모주(最初公募株)는 왜 이처럼 과도하게 저가발행(低價發行)되고 있는가에 대하여 원인을 규명하고 그에 따른 해결책을 제시하고자 함에 있다. 발행가격결정 자율화 기간동안의 자료를 이용하여 실증적 분석을 한 결과, 우리나라의 저평가는 미국보다 통계적으로 유의하게 큰 것으로 확인되었다. 이러한 이유를 규명하기 위하여 이론적 모형을 제시하고, 우리나라와 미국을 중심으로한 다른 국가들의 발행가격 결정과정에 대한 제도적인 차이점을 검토하였다. 이론적 모형에서는 발행기업과 주간사회사가 수요의 크기를 예측하여 수요의 불확실성 정도가 낮으면 저평가의 크기가 적어진다는 것을 보였다. 제도적인 차이점들을 검토해 본 결과, 우리나라의 발행가격결정이 일반투자자들의 수요를 전혀 고려하지 않는 공급자의 사전가격결정방식을 택하고 있음에 반해, 미국에서는 발행가격대를 표기한 예비사업설명서와 로드쇼우(Road Show) 둥을 통해 투자자들의 수요예측을 하고 있으며 일본이나 프랑스는 발행주식의 일부를 경쟁 입찰에 부침으로써 투자자들이 발행가격결정에 참여하여 발행가격결정의 합리성을 유지하고 있다. 따라서, 우리나라의 저평가의 크기가 다른 국가들에 비하여 큰 이유는 우리나라의 공모주 발행가격 결정과정에서 투자자의 수요를 전혀 고려하지 않기 때문일 수 있으며, 이러한 저평가의 크기를 줄이기 위해서는 어떠한 형태로든지 발행가격 결정과정에 실수요자인 일반투자자가 참여하는 방식이 채택되어야 한다.

Short Abstract: This study investigates the effects of price and other variables on consumers' purchasing decision for eco-friendly foods. This study pays particular attention to the effect of price that may influences consumers' decision to buy eco-friendly foods. The empirical findings are summarized as follows. First, the descriptive results of the survey show that "detailed explanation for the products," "distribution channel," "reliability of the labeling for eco-friendly foods" are more important than price and other factors. Second, the ordered logit analysis vindicates that such situational factors as number of children and existence of patient in the family are the most important variables to explain the degree of satisfaction level when considering the price level of eco-friendly foods. Finally, the results of the conjoint analysis indicate that consumers regard distribution channel as the most important factor, and reliability of labeling system and level of price position second and third, respectively. The present study concludes with suggesting some policy implications and directing future studies.

Takenoshin Nakai (1882-1952), Japanese taxonomist and professor of the University of Tokyo, who was one of Korean flora specialists, conducted his plant exploration from 1909 to 1942 after he completed two volumes of Flora Koreana. His collections, which are currently deposited at the University of Tokyo herbarium (TI), are important research resources. Since all collection sites were simply described in his collection sites in Romanized characters based on Japanese pronunciation, it is difficult for Korean as well as Japanese botanists to pinpoint those sites using the current or the old Korean maps. No single literature has been available regarding his collection routes and sites, although this information is essential to current plant systematic research in Korea. From this current study, all locality names were reviewed based on his own collections as well as his written literatures, and those were listed as the order of his collection dates with seven maps here.

In this paper, we implement an automatic speech segmentation and labeling system which marks phone boundaries automatically for constructing the Korean speech database. We specify and implement the system based on conventional speech segmentation and labeling techniques, and also develop the graphic user interface(GUI) on Hangul $Motif^{TM}$ environment for the users to examine the automatic alignment boundaries and to refine them easily. The developed system is applied to 16kHz sampled speech, and the labeling unit is composed of 46 phoneme-like units(PLUs) and silence. The system uses both of the phonetic and orthographic transcription as input methods of linguistic information. For pattern-matching method, hidden Markov models(HMM) is employed. Each phoneme model is trained using the manually segmented 445 phonetically balanced word (PBW) database. In order to evaluate the performance of the system, we test it using another database consisting of sentence-type speech. According to our experiment, 74.7% of phoneme boundaries are within 20ms of the true boundary and 92.8% are within 40ms.

The purpose of this study is to examine how the titles and corporate names of Japanese scholarly journals are treated, and how well the authority control is implemented to assist the access with various names and forms of names to the OPACS. Without the help of either references or internal links among those names and forms of names in the DBs, users are likely to fail in getting the right results. In this study, the cataloging records for serials from the National Assembly Library, KISTI, Yonsei University and the KERIS were examined, and the comparison was made with the records from the NACIS-WebCat of the National Institute of Informatics in Japan. Major findings include (1) the lack of consistency in applying cataloging rules, (2) the lack of proper authority control in treating corporate names, and (3) the lack of references or links among names and variant forms of names. The overall improvement of cataloging practices and application of authority control is strongly recommended for enabling users to access better to those DBs of interest.

In this study, we investigated how multiplication by 2-digit numbers had been taught in elementary mathematics textbooks of Korea, Japan, Singapore, and USA. As a result of analysis, we found as follows. Korean textbooks do not teach the multiplication by 10 and the multiplication by power of 10, but Japanese, Singapore, and US textbooks explicitly teach related content. In the '×tens' teaching, Japanese and American textbooks teach formally the law of association of multiplication applied in the process of calculating the partial product of multiplication. The standard multiplication algorithm generally followed a standard method of recording partial product result according to the law of distribution, but the differences were confirmed in the multiplication model, the teaching method of the law of distribution, and the notation of the last digit '0'. Based upon these results, we suggested some proposals for improving the multiplication teaching.

This paper examines research ethics in using the generative AI ChatGPT for research purposes. After reviewing traditional themes of research ethics and relevant principles, it will be argued to be inappropriate to discuss ChatGPT-related issues only from the perspective of permission, detection, and punishment. We need to consider the fundamental problem that the current rules pose concerning the way ChatGPT works. This leads to the proposal that the usage of ChatGPT should be clearly noted when it is used for research purposes and that some unresolved issues should be recognized. Although the advantages of ChatGPT cannot be denied, consensus on the appropriate scope of use is needed from perspectives of the research community and researcher's social responsibility. As generative artificial intelligence technologies are still in the early stages of development, researchers should pay attention to relevant research ethical issues, while not making hasty conclusions. In the conclusion, it will be also proposed to discuss and make a consensus regarding the definition of research that is premised on existing research ethics, but challenged with the advent of ChatGPT and AI technology.

스트립 방식으로 촬영된 위성영상의 기하학적 모델링시에는 일반적으로 단위모델별로 위성영상에서 식별이 용이한 지점을 지상기준점으로 선정하여 영상에서의 좌표를 해석도화기나 컴퓨터 화면상에서 획득하고, 그에 대응하는 지상좌표는 현지측량이나 기본지도로부터 얻는다. 현지측량방법의 경우에는 정확하고 신뢰성있는 좌표를 제공해 줄 수 있는 반면에 현지로의 접근이 용이해야 하고 비용과 시간이 많이 소요되며, 소축척의 기본지도상에서 직접 독취하는 경우에는 지도자체에 내재된 오차의 정도가 불명확하고 지상기준점으로 선정한 지점이 명확히 표기되어 있지 않은 경우가 있으므로 영상좌표 측정시에 오차의 유발 가능성이 크다. 특히 영상 해상도 $5{\sim}10m$의 연속된 화상을 3차원 기하학적 모델링을 수행하기 위하여 현지측량에 의해 지상기준점을 획득하는 방법은 경제성 및 효율성 측면에서 불리하다. 따라서 본 연구에서는 삼각점 조서를 이용하여 연속촬영된 SPOT 위성영상을 스트립 단위로 모델링하여 영상해상도 수준의 위치정확도를 얻을 수 있는 연속화상 모델링기법을 제시하였다.
