In metropolitan area, intersections having turn Prohibitions are often found and it is important to consider them in path planning. This Paper presents a new path planning method road networks having turn prohibitions. A new road network model is proposed in which an alter-native route for each turn-Prohibition is constructed in off-line using U-turn or P-turn and then Put into road network database. The proposed network model is efficient since it requires no virtual nodes that are usually used in the conventional road networks to represent turns at intersections. In order to find a shortest path with the proposed network, a new shortest path algorithm is proposed. A knot for the turn-Prohibited node is newly defined and is used in comparing the cost of the alternative route with that of the other path.

The study was designed to examine the present state of the provider-role consciousness of married working women in Korea and to identify five variable-clusters which were drawn from the theoretical perspectives. The subjects of this study were 573 married working women whose husbands also had their work. The statistical methods adopted for data analyses were frequencies. oneway ANOVA. Scheffe-test t-test, and multiple regression analysis. The major findings of this study can be summarized as follows; 1) The level of the provider-role consciousness of married working women was slightly high. 2) As for the aspects of the individual attribute variables. educational level job income age native area motive of work. and sex-role identity significantly influenced the provider-role consciousness of married working women. 3) Concerning the family background variables marriage duration number of children mother's experience of employment father's educational level and husbands's income were significantly related to the provider-role consciousness of married working women, 4) As for the social relationship variables. degree of participation in social associations significant others' attitudes toward housewife's work degree of domestic role sharing with husband and wife/husband income ration significantly affected the provider-role conscious-ness of married working women. Based on these findings it came to be revealed that multidirectional perspecitves were useful to identify variables which could predict the provider-role consciousness of married working women, Also it was revealed that the significant others' approvals for women's work were necessary to the establishment of the provider-role consciousness of married working women.

This study is to establish the Incheon Metropolitan City Arboretum Development Plan (IMADP) as a capacity building both for plant diversity conservation and nature friendly leisure activity areas of Incheon Metropolitan City, Korea. The arboretum planning area is located within territory of the Incheon Grand Park Based on the IMADP, the arboretum was divided into three display spaces; the Urban Greening Garden, the Rare and Endangered Plant Species Garden and the Theme Garden. Detailed planting guidelines were suggested according to the three garden areas. The Urban Greening Garden was designed to display the following three; the relevance techniques, the model, and the practical uses of plants that are regarded to an urban greening. The Rare and Endangered Plant Species Garden (REPSG) was planned for the collection and display of the rare and endangered native plants in the territories of Incheon and the island seashore. Also, the REPSG includes the education purposes of comparing and displaying taxonomically related plant species. The Theme Garden was projected for the collection and display of plant species that have long been familiar to Korean culture and which are also used in our daily life.

The primary purpose of this study was to identify the diversity and embellishment of American Indian clothing and relationship between culture and clothing in American Indian Culture Areas. After the introduction of European material culture, change in American Indian clothing was conducted. The result of the Study as follows: 1. The most influential factors affecting the diversity of American Indian clothing were environmental factors. Climates and geographical features, Raw material were reflected in clothing style and clothing material in each culture Area. 2. Economic situation and life style were shown to be influential to clothing development. The best known instance of this was greatly elaborated clothing and personal adornment of the Plains who had higher stand of life and nomadic life style. 3. Religious concepts were important factors influencing American Indian clothing. Indian tribes had different ritual performance they used particular motifs in clothing. Clothing, such as "ghost shirt", Apache medicine shirt and Pueblo ceremonial clothing, served hidden pur- poses. 4. Techenology was another factor identified in this study as influencing American Indian clothing. Especially, weaving skills of Southwest played a great role in textile development. Pueblo "manta" and Navaho "bil" were famous for Indian costume. 5. European material culture allowed great change of traditional native Indian clothing. American Indian had new material, new styles, new concept of clothing. 6. American Indian, although Indian applicated European trade goods, was actually quite conservative in retaining traditional designs and modes of decoration. Asthetics and traction of American Indian were reflected in American Indian clothing.d in American Indian clothing.

Much research has been done on the rues differentiating the three Korean stops in word initial position. This paper focuses on a more neglected area: the acoustic cues differentiating the medial tense and lax unaspirated stops. Eight adult Korean native speakers, four males and four females, pronounced sixteen minimal pairs containing the two series of medial stops with different preceding vowel qualities. The average duration of vowels before lax stops is 31 msec longer than before their tense counterparts (70 msec for lax vs 39 msec for tense). In addition, the average duration of the stop closure of tense stops is 135 msec longer than that of lax stops (69 msec for lax vs 204msec for tense). THESE DURATIONAL DIFFERENCES ARE 50 LARGE THAT THEY MAY BE PHONOLOGICALLY DETERMINED, NOT PHONETICALLY. Moreover, vowel duration varies with the speaker's sex. Female speakers have 5 msec shorter vowel duration before both stops. The quality of voicing, tense or lax, is also a cue to these two stop types, as it is in initial position, but the relative duration of the stops appears to be much more important cues. The duration of stops changes the stop perception while that of preceding vowel does not. The consequences of these results for the phonological description of Korean as well as the synthesis and automatic recognition of Korean will be discussed.

Fish community structure in the Pyeongchanggang River was investigated from April to November 2009. About 900 individuals representing 24 species from eight families at six sites in the Pyeongchanggang River were collected. It was similar to the 2001's survey and it was less than 2006's survey. The Korean endemic species, Zacco koreanus was the most abundant, whereas subdominant species were native species, such as Pungtungia herzi, Zacco platypus, Rhynchocypris kumgangensis and Rhynchocypris oxycephalus. Three endangered species were collected at the sampling area, Acheilognathus signifier (relative abundance [RA] 0.9%), Pseudopungtungia tenuicorpa (RA 1.4%), and Cottus koreanus (RA 3.6%). One natural monument species, Hemibarbus mylodon, was included. According to the analysis of ecological indicator characteristics, the relative proportion of tolerant species was 6.3% (57 individuals), whereas the proportion of sensitive species was 65.9% (593 individuals). Species evenness, richness and diversity indices decreased gradually through the month from April to November during the study. Community indices in Pyeongchanggang River showed a high evenness index (J'>0.6), a low level of species richness (R<3.5) and a medium level of diversity (1.5

A three-dimensional(3D) Monte Carlo simulator for boron ion implantation into <100>single-crystal silicon considering the mask structure has been developed to predict the mask-dependent impurity doping profiles of the implanted boron at low energies into the reduced area according to the trend of a reduction in the size of semiconductor devices. All relevant important parameters during ion implantation have been taken into account in this simulator. These are incident energy, tilt and rotation of wafer, orientation of silicon wafer, presence of native silicon dioxide layer, dose, wafer temperature, ion beam divergence, masking thickness, and size and structure of open window in the mask. The one-dimensional(1D) results obtained by using the 3D simulator have been compared with the SIMS experiments to demonstrate its capabilities and confirem its reliability, and we obtained relatively accurate 1D doping profiles. Through these 3D simulations considering the hole structure and its size, we found the mask effects during boron ion implantation process.

This report deals with the effect of levels of concentrate supplementary feeding (Nil, 0.25% BW and 0.75% BW) on the productivity of different genotypes (Thai native (TN), 25% Anglo-Nubian (AN), 50% AN and 75% AN) of female goats grazing newly established pasture in a tropical area. The major species of grass was Brachiaria mutica (33%) and of legumes was Centrosema pubescens (34%). There was no significant (p>0.05) difference between nil and 0.25% BW supplementary feeding for growth rate ($g/kg^{0.75}/d$). However, goats fed 0.75% BW supplementary feeding had significantly (p<0.01) higher growth rates than did other treatments. There was no significant (p>0.05) difference among genotypes and between age for growth rate. There was no interaction between feeding and genotype for growth rate.

This study is on dancing dresses of the costumes of Gum-Mu(劍舞, sword dance) in southern, central, and northern region of Korea, focusing on the origin, characteristics and the way of dance. The reason why the Gum-Mu is full of local color is that royal Korean Gisaeng(妓生) and local Gisaeng returned to their hometown and propagated this dance to each regional Kyobang. They combined court sword with each local dance and music and formed the present style of regional Gum-Mu. Dance and music native to area, which has formed today's regional Gum-Mu. The composition of current dancing costume of the sword dance is Jeogori, Chima, Jeondae(戰帶), Jeonrib(戰笠), Kwaeja(快子) Also, The complement colors harmonizing with color of Yin-Yang & Five Elements. which are yellow, blue, white, red, and black, are usually used. And the masculinity in dance were expressed withmore use of blue, and red in the opposite but if a sword dance takes on masculine character, blue color is more used, if feminie character, reddish colors, such as pink and red, are used. Thus, JinJu, Honam, Haeju, Pyeongyang dancing Suit of Gum-Mu feature blue color, Tongyeong, Kyeonggi, Court(seoul)dancing Suit of Gum-Mu feature reddish color.

In the middle areas of South Korea, we collected 308 wild herbaceous species for studying the possibility of landscaping and, growing them at West in Yongin country of Kyunggi province. We observed their vegetative and flowering characteristic. And the result is as follow: 1. 76 species(24.7%) such as Hosta capitata, etc. of them are thought useful for flower-bedding or landscaping for park and ground-covering, while 94 species(30.6%) are regarded useful for ground-covering, potting and indoor-planting. They are Nepatica maxima and Thaliticum minus var. hypoleucum, etc. 46 species(15%) seems to be useful for flower-bedding, ground-covering and potting. 2. 264(85.7%) of all the observed species are for the enjoyment of their flowers, while 36 species(11.4%) for the enjoyment of their leaves, and 9 species(2.9%) for their fruit. They are Viburnum dilatatum, etc. 3. As for the relation of their habits to light conditions, 148 species(48%) grow int he full sun of more than 50,000Lux, 138 species(44.8%) usually in in the half shade of 20,000 to 30,000Lux, 15 species(4.9%) in the shade of some 10,000Lux, and 7 speciese grow either in the full sun or in the shde. 4. some species such as Wasabia koreansa, Allium succuliferum, Asterglehni, Ligulariafisheri, Ligularia stenocephala Epimedium koreanum are considered available as edible plants as well as ornamentals plants, and Houttuynia cordata. Saururus chinensis, Epimedium koreanum need to be further developed not only as ornamental plants but also medicinal plants.
