오늘날 전자수첩에서부터 셀룰라 폰(휴대폰), PDA, 그리고 HFC 등에 이르기까지 휴대형 정보기기의 사용이 급증하고 있다. 이러한 장비는 한글을 입력하기 위한 한글자판을 제공하는 경우가 대부분인데, 전자 수첩과 같이 물리적 자판이 제공되는 경우와 터치 스크린 사에 소프트웨어적으로 제공되는 경우가 있으며, 두 경우 모두 자판의 크기 때문에 한 두 손가락만을 이용하여 글자를 입력하게 된다. 이 논문에서는 이러한 경우, 보다 빠르게 한글을 입력할수 있는 한글 자판 배열을 유전자 알고리즘을 이용하여 찾는 것에 대하여 연구한다. 실험 결과 유전자 알고리즘을 이용하여 생성한 자판이 기존의 자판에 비하여 평균적으로 약33%~49% 정도 빠르게 글자를 입력할 수 있다.

The dorsal lingual papillae of Myotis macrodactylus were investigated morphologically using scanning electron microscopy. Three types of lingual papillae from Myotis macrodactylus were recognized. The filiform(Fi) papillae were distributed over the entire dorsal surface of the tongue, and they could be classified into 5 types of papillae by the shape, size and number of the protrusion. Type I was distributed on dorsal surface of the apex in the anterior region of the tongue, has a crow-like shape with ten to fifteen formed projections. Type II was located in the medial portion of the anterior region of the tongue, has an eight to ten spin-like protrusion. Type III was distributed on the medial portion of the tongue, has a scale-like papille with five to seven protrusion. Type IV was distributed on the both lateral portion of the posterior region of the tongue, has a small conical papillae, does not have needle projection. Type V have not needle projection, a large of conical papillae, on the both lateral portion of the posterior region of the tongue. Most Fu(Fungiform) papillae were distributed the both lateral region or medial portion of the posterior region of the tongue, has a round or oval shape with $40{\sim}45$ papillae. The small $(65{\mu}m)$, meddle $(75{\mu}m)$ and large $(120{\mu}m)$ fungiform papillae were distributed on dorsal surface of the apex in the anterior, the both lateral portions and medial portion of the posterior region of the tongue, respectively. Two large oval vallate (V) papillae are located in the medial portion of the posterior region of the tongue. In conclusion, the morphology of lingual papillae is useful to determine species relationship among Myotis species. It suggests that the difference of types and number of lingual papillae caused by the difference of food habit.

In this study, the potash glass beads of 281 samples in 30 sites analyzed until now were classified according to the chemical composition. And the color, size, manufacturing technique and distribution period were compared. Korea potash glass beads are divided into 3 types depending on the stabilizer content. I, II type is the CaO and $Al_2O_3$ content of less than 5%. Relatively, I type has a high CaO and II type has a high $Al_2O_3$. In contrast, III type comprises more than CaO 5%. I, II type is the saltpetre, III type is estimated using plant ash as row material of flux. A review of the properties by type, I type is cobalt blue, copper blue and purple beads. The outer diameter is sized to the range 1.4~7.4mm. Also it was produced by the drawing technique. It was used continuously from BC 1C until around AD 6C. On the other hand, II type is outer diameter of 1.9~3.6mm and a copper blue beads. manufacturing technique is the same as the I type. This seems to have been in use since around AD 1C to 4C. Finally, III type is brown, colorless, amber beads and an outer diameter of about 10mm. It was formed by winding technique and appeared in the tombs of Goryeo and Joseon Dynasty. As a result, 3 types of potash glass beads distributed in Korea is likely to flowing through the various trade routes from different provenances.

Rat liver sinusoids were observed by scanning electron microscopy. The sinusoids were provided with fenestrations which were divided into three types; small, medium-sized and large. The small fenestrations were usually gathered into clusters. The medium-sized fenestrations were either individually organized or in the cluster of small fenestrations. The large fenestrations were usually accompanied by small or medium-sized fenestrations. The lobule was divided into three zones; peripheral, intermediate and central, according to the distribution pattern of the fenestrations. The sinusoid providing with small fenestrations (type I) were predominant in the peripheral zone. The sinusoid showing medium-sized fenestrations (type II) were frequently observed in the central zone. The sinusoid having large fenestrations (type III) were abundant in the intermediate zone. This evidence indicate that the sinusoidal fenestrations become larger toward the intermediate zone from the peripheral zone of the lobule and progressively smaller toward the central zone. However, the fenestrations observed in the central zone seem to be larger than those seen in the peripheral zone of the lobule.

This study aims to classify lower trunk body types of Chinese men in their middle age (30s and 40s) and suggest the standard for them to design slacks pattern. Mollison's relation deviations were used to analyze the direct measurement items in this research compared to those of Size Korea 2004. Though Korean middle-aged men were higher in most items than Chinese counterparts, all items except mid-thigh circumference and side hip length were merely within the range of ${\pm}1\sigma$. According to the results of size classification by absolute values, factor analysis extracted to 2 factors(horizontal size of lower body and vertical size of lower body), and cluster analysis brought about 3 types(type1: tall and thin trunk (36.9%), type 2 : normal height and thick trunk(45.5%), and type 3 : short and normal trunk(17.6%) with some significant differences among them. Also, the results of shape classification by index values, they were extracted 4 factors (waist-hip flatness, waist-hip cross section, vertical waist-groin and hip-surface length) by factor analysis and revealed 3 types(type 1: different waist-hip width, thick, long waist, long upper hip, and short hip-surface length(27.8%), type 2 : different waist-hip width, flat, short upper hip, high hip and groin, and average hip-surface length(29.4%), and type 3: small waist-hip width, thick, average upper hip, and short hip-surface length (42.8%)) with significant differences among them by cluster analysis. The results of standard body types by shape-size combination, 19subjects(10.16%) under these values are regarded as standard body types. Significance was not seen in all items in the t-test results between the total group and the standard group. The latter had lower variation coefficients and smaller individual differences than the former. However, in-depth research is required for generalization since this research is limited to a small number of subjects in Ningbo of Zhejiang.

For the purpose of evaluating the restoration effect of vegetation, in this study, the areas where vegetation was restored had been monitored for 6 years, from 2008 to 2013. The areas were restored through some techniques by utilizing forest resources and nearby forest resources: biotope restoration method, forest topsoil paving method and small diameter trees planting method. Biotope restoration method is indicated the most similar properties to the existing natural forest just after they were restored because the forest likely to be deteriorated was transplanted. Forest topsoil paving method is expected that long-time will be taken for plants to grow to form the tree layer. However, the method is expected to acquire high restore the places of empty lands such as cutting areas. Community planting method is coverage can be increased for short time, relying on the sizes of planted trees, and the tree layer can be formed. Consequently, this method is expected to create high effect if the sizes of trees are considered after the right judgement of candidate site for restoration. This study is meaningful in that each type of restoration is monitored to observe the change of triggered by the succession process to forest. The study results can play as the reference data which can be utilized and applied to the area requiring vegetation restoration or to the area facing the damage of forest resources.

Taxonomic studies on morphological, principal component analysis (PCA), palynological, RAPD and PCR-RELP analysis were conducted to intraspecific relationships of Rubus oldhami. Three types of Rubus oldhami based on the flower characters such as petal length and number were used in this study. Among the 14 morphological characters, perianth length, calyx lobe length, apical leaflet shape and leaflet length were used to distinguish for each type. The pollen characters such as shape, aperture number, surface sculpture were showed very similar among three types. Eight primers out of 20 arbitrary primers were screened for three types, and were revealed 33 ($60\%$) polymorphic bands. The phonogram by RAPD data showed incongruent with morphological analysis. Even though ten restriction endonucleases produced 20 restriction sites, polymorphic bands were not observed. Based on the results, three types of Rubus oldhami divided well by morphological characters, but pollen and DNA data were not supported. Therefore, type 1 and 2 which different from type 3 by flower characters considered as a temporary hybrid or ecotype because of their similar habitats.
