  • Four external and 27 cranial characters of Korean field mice (Apodemus peninsuluek from nine localities in eastern Asia, representing ave subspecies, were analyzed by multivariate statistical methods. Three forms were recognized: a large-size form from Korea (subspecies peninsulael, southern Manchuria (praeto4, and northern Manchuria (majofi a middle-size form from urestern Siberia (tschergal and southuvestern China (sowerbyi); a small-size form from northeastern China (sowerbyi). It is also revealed that variations among the three forms are clinal rind circular. It is confirmed that Apodemus peninsuloe could be classified into two subspecies (peninsulae and sowerbyl) within the distribution range in the continent of Asia, as noted tv Corbel (1978). However, it is found that subspecies peninsulae includes praetor and moior and that subspecies sowerbyi includes tscherga, indicating that subspecies tscherga is not the synonym of subspecies peninsulae, but that of subspecies sowerbyi.

  • Pre-existing pattern recognition techniques, in the case of character recognition, have limited on the application field. But CAI character learning system and writer's recognition system are very important parts. The application field of pre-existing system can be expanded in the content that the learning of characters and the recognition of writers in the proposed paper. In order to achieve these goals, the development contents are the following: Firstly, pre-processing method by understanding the image structure is proposed, secondly, recognition of characters are accomplished b the histogram distribution characteristics. Finally, similarity measure functions are defined from standard character pattern for matching of the input character pattern. Also the effectiveness of this system is demonstrated by experimenting the standard primitive image.

  • The subgenus Idioglochina Alexander, 1921 belongs to the genus Dicranomyia Stephen, 1829 and has a special habitat unlike other congeners. The larval stage inhabits marine algae near the intertidal zones. The most distinctive characters are found in the antennae with inner face of flagellar segments extended to produce a serrate form. A total of 30 species of the subgenus Idioglochina are recorded with the distribution is restricted to the Pacific and Indian Ocean regions. In this study, the subgenus and its species D. (I.) tokara (Nobuchi, 1955) are newly added to the Korean fauna. This species was previously recorded in Japan as an endemic species, but it was collected from Jeju Island. A redescription, period of activity, habitat information, and photographs of diagnostic characters of the species are provided. The female ovipositor is photographed for the first time.

  • A set of rice recombinant inbred lines was developed from a cross between a Tongil type variety, Nonganbyeo, and an indica variety, BG276, by the single seed descent method. The number of the lines in the population was 272. All the agronomic characters studied except ADV (alkali-digestion value) showed continuous variation among the RILs, implying that their inheritance mode should be quantitative. The patterns of the variation in the RILs were either normal or skewed distribution. ADVs of RILs were segregated into two groups with 1:1 ratio, indicating that ADVs in this KIL population might be controlled by one major gene. Transgressive variations were also observed in all characters. Heritability values of the characters varied from 0.488 in brown/rough rice ratio to 0.895 in alkali-digestion value. In the analysis of genotypic and phenotypic correlations, the character of yield was positively correlated with 8 different agronomic characters. The number of panicles per hill was negatively correlated with culm length, panicle length, and number of spikelets per panicle. Grain length was positively correlated with grain width, grain thickness, grain length/width ratio, white belly, ADV, and amylose. However, grain length/width ratio was negatively correlated with grain width. White core was also negatively correlated with white belly and ADV.

  • This study aims to conduct research into the property of costumeplay that has been established with our unique characteristics despite the critics from the existing generation, and the cospre style preferred by costumeplayers. The research methods include literature study, existing research, and a survey targeting costumeplayers who make costumes upon order or borrow costumes on websites. The findings are as follows. 1. From the results of the survey, 77% of the participants in the costumeplay were secondary school students, 16% were college students, and 5% were primary school students. 2. The distribution of the residences of the costumeplayers was found to be mostly centered in two areas including Seoul/Gyeonggi and Gyeongsang/Busan, which were 39% and 37% each. This is probably because Seoul Comic and Busan Comic were regularly taking place, and these are relatively economically affluent areas and locations where the rapid exchange of Japanese culture occurs. 3. For the cospre style preferred by costumeplayers, 57% of respondents preferred costumes for reviving characters, 18% of them for fan-cospre and 14% of them for reviving a character and creating new characters. Costumeplayers preferred cospre costumes for reviving characters rather than for creating new characters. 4. Most respondents preferred a character-oriented design, posting 31.9%. Next, 17.5% of them selected the Lolita look This is probably because the Lolita look which is much favored in the latest fashion trends affects them, and the rest of the respondents preferred a fantasy/SF group, visual, uniform, and maid look, in order. 5. For costs required for costumeplay for 1 time, 39% of respondents spent about KRW $100,000{\sim}150,000$, and 24% of them about KRW $150,000{\sim}200,000$. However, for buying accessories or small items, over 50% of them spent KRW $30,000{\sim}40,000$.

  • 현재 농공단지의 지역적 공간분포 특성파악이 미흡한 실정으로 전국 농공단지의 규모측면에서 매출액, 종사자를 지표로 규모성장률 측면에서는 매출액성장률, 종사자성장률을 지표로 공간적 특성을 파악하였다. 분석을 위해 포트폴리오 분석과 ArcView 3.2를 활용한 IDW 내삽 방법을 이용하였다. 분석결과 전국 농공단지의 대부분은 규모와 규모성장률이 낮은 값을 보였다. 지역별로 포트폴리오 분석결과 경남지역이 규모와 규모성장률 값이 높게 나타난 반면 IDW 내삽에서는 전북지역이 높게 나타났다. 이는 개별적인 농공단지의 값과 주변 농공단지와 연계되었을 때의 값의 차이를 보이는 것요로 농공단지의 개별적인 활성화뿐만 아니라 주변 농공단지와 연계된 지원과 관리방안이 휠요하다.

  • After establishing the rules for the phonetic transcription in French, quantitative analysis on the given text, Waiting for Godot, is performed. Analyzing the text by investigating the influence of phoneme distribution is very interesting in the phonostylistic point of view. Since the phonetic transcription rules are useful for its automation, the rules are carefully established in this paper. From the results of the phonetic transcription, we can investigate the distribution of individual phonemes and the different phoneme groups between dialogues and scenery indications for various characters.
