Various geotechnical information is required to evaluate the stability of the ground and a foundation once liquefaction occurs due to earthquakes, such as the soil strength and groundwater level. The results of the Standard Penetration Test (SPT) conducted in Korea are registered in the National Geotechnical Information Portal System. If geotechnical information for a non-drilled area is needed, geostatistics can be applied. This paper is about the feasibility of obtaining ground information by the Empirical Bayesian Kriging (EBK) method and the Inverse Distance Weighting Method (IDWM). Esri's ArcGIS Pro program was used to estimate these techniques. The soil strength parameter of the drilling area and the level of groundwater obtained from the standard penetration test were cross-validated with the results of the analysis technique. In addition, Multichannel Analysis of Surface Waves (MASW) was conducted to verify the techniques used in the analysis. The Buk-gu area of Pohang was divided into 1.0 km×1.0 km and 110 zones. The cross-validation for the SPT N value and groundwater level through EBK and IDWM showed that both techniques were suitable. MASW presented an approximate section area, making it difficult to clearly grasp the distribution pattern and groundwater level of the SPT N value.

The purpose of this presentation is to review the situation of the Cheju broiler industry peculiarized with the integrated production and marketing system to some degree, which is not prevailed in the whole broiler industry in Korea, so as to study the case of the Cheju industry from the viewpoint of an economic integration. The economic integration in the broiler industry is grouped into three patterns： non-integration, quasi-integration and complete integration, which generally exist under the different type of market competition. The quasi-integration tends to be formed at all phases where the complete integration is not fully implemented, but the non-integration has begun to change its nature into partially integrated structure. The Cheju broiler industry is characterized by the geographical location of isolated market so that factor supplies and broiler products are marketed in the different conditions from those of mainland Korea, somewhat in an oligopolistic pattern. It was since early 1980's that the industry successfully had three dressing plants merged into one by virtue of entire growers ownership, which opened an era of an integrated industry centered on the function of dressing birds. The case of Cheju broiler industry today is to be referred to as a typical quasi-integration which is coordinated the function between growing and dressing birds directly and extended the functional cooperation to distribution of products indirectly, while factor supplies are traded independently. As a result of a quasi-integration, the growers are able to receive a fixed price set by the dressing plant of growers that has the power to adjust the supply of and demand for broilers produced and consumed in the Island. There are some problems, however, in the integration of the Cheju broiler industry, stemming mainly from the process of the structure change, ： 1) the difficulty of controlling the production of broilers, 2) continuing pressure on the integration by non-integrated sectors, 3) the challenge on the stabilized broiler market from the mainland, 4) limited effectiveness of consumer education activities, and 5) lack of leadership for the industry development through integration. It is projected that the partially integrated Cheju broiler industry will be continually developed toward the direction of a complete integration in due course, as the currently independent supply sectors are to be backward integrated. The case of the Cheju broiler integration, therefore, could be used as a reference for making the whole broiler industry in Korea develop toward the integrated structure in the future.

This study was carried out to illiminate the diversity of vascular plants by making list of rheophyte and hydorphyte plants at Yugu stream. This study was conducted from Aug., 2009 to Sept. 2010 at 7 points. Based on the voucher specimens, vascular plants from investigated areas were 88 families 229 genera 290 species 3 subspecies 30 varieties 5 forms, totally 328 taxa. Korean endemic plants were 3 species such as Forsythia koreana (Rehder) Nakai (planted) and Paulownia coreana Uyeki (planted), and Weigela subsessilis (Nakai) L.H. Bailey. The rare and endangered plants were designated by Korea Forest Service were 4 taxa, such as Penthorum chinense Pursh, Acorus calamus L., Lilium callosum Siebold & Zucc. and Iris ensata var. spontanea (Makino) Nakai. Floristic special plants were totally 26 taxa, which were grade V of 2 taxa, grade IV of 2 taxa and grade III of 9 taxa. Naturalized plants were 27 taxa, that was 8.3% of whole discovered vascular plants in this area. Even naturalized plants has not influence on the vegetation of Yugu stream. Since village was composed along the stream and the roads and banks were linked, naturalized plants were flowed continuously into this region. So, strategy of the conservation for this region should be designed. Based on flora, 3 types of group were discriminated such as main stream type (4 points), branch stream type (2 points) and reservior type (1 point). Each group has difference in composition of plants.

This study was carried out in the Chungnam National University grassland experimental field from October, 2007 to December, 2009 in order to find out the growth characteristics of the wildflowers, the seasonal anthesis distribution of the wildflowers and the botanical composition of the wildflowers which were altogether composed of 50% sheep fescue and 50% wildflowers. The experimental species contained 34 species in total consist of sheep fescue (fundamental turfgrass), 4 native wildflowers, and 29 introduced wildflowers belonged. At the time of the anthesis of the wildflowers, the average length was 30.0 cm one year later and 35.6 cm two years later. They bloomed out into ten colors, but into simplified colors during August, September, and October. The peak of the blooming was May and June and blooming pattern leant from August to October. Especially, at the age of two (2009) the color, seasonal distribution, and consistency emerged as problems owing to the reduction of annual wildflowers after winterization. The annual botanical composition of wildflowers, sheep fescue, and weed came to 28%, 55%, and 17% each one year later (2008) and 24%, 60%, and 17% each two years later (2009). Based on this result, cultivating wildflower grassland (sheep fescue 50% + wildflowers 50%) is the proper method for making up such flatlands as parks and riversides in a short period (one year) for the purpose of commanding a fine view.

In this study, we was measured the radiance reflectance by using multi-spectral image of low resolution camera(LRC) which will be loaded in the multi-purpose satellite(KOMPSAT) to use the data in analyzing water pollution. Also we investigated the possibility of extraction of water quality factors in rivers and water body by using high resolution remote sensing data such as Airborne MSS. Especially, we tried to extract the environmental factors related with eutrophication, and also tried to develop the process technique and the radiance feature of reflectance related with eutrophication. The results were summarized as follows: First, the spectrum of sun's rays which reaches the surface of the earth was consistent with visible rays bands of 0.4${\mu}{\textrm}{m}$~0.7${\mu}{\textrm}{m}$ and about 50% of total quantity of radiation were there. And at around 0.5${\mu}{\textrm}{m}$ of green spectral band in visible rays bands, the spectrum was highest. Second, as a result of the radiance reflectance Chlorophyll-a represented high spectral reflectance mainly around 0.52${\mu}{\textrm}{m}$ of green spectral band, and suspended sediments and turbidity represented high spectral reflectance at 0.8${\mu}{\textrm}{m}$ and at 0.57${\mu}{\textrm}{m}$ each. Third, as a result of the water quality analysis by using Airborne MSS, Chlorophyll-a could have a distribution chart when carried out ratio of B3 and BS to B7. And Band 7 was useful for making the distribution chart of suspended sediments. And when we carried out PCA, suspended sediments and turbidity had distributions at PC 1 , PC 4 each similarly to ground truth data. Above results can be changed according to the change of season and time. Therefore, in order to analyze more exactly the environmental factors of water quality by using LRC data, we need to investigate constantly the ground truth data and the radiance feature of reflectance of water body. Afterward in this study, we will constantly analyze the radiance feature of the surface of water in water body by measuring the on-the-spot radiance reflectance and using low resolution satellite image(SeaWiFs). Besides, we will gather the data of water quality analysis in water body and analyze the pattern of water pollution.

This research deals with the multi-modal continuous network design problem to resolve the transportation policy problems for constructing and operating transportation facilities with considering the mutual decision-making process between transportation operator and user in the multi-modal network. Particularly, in the consideration of changes in travel pattern between transport modes due to the changes in transportation policy, road network for passenger car and transit network for public transportation are considered together. In the development of network design model, more rational Stackelberg equilibrium(cooperative game) rather than more general Nash equilibrium(non-cooperative game) approach is used and sensitivity analysis considering transport mode is used. A multi-modal continuous network design model in this study is developed for the arbitrary continuous network design parameters(${\epsilon},\hat{\epsilon},p$) of transportation policy decisions. As examples of application and evaluation for these design parameters, the developed model is applied to calculate 1)the optimal capacity of road link in the road transport policy, 2)the optimal frequency of transit line in public transport policy and 3)the optimal modal split in transport modal share policy.

Knit products which had been limited only to underwear, recently became popularized, fashionized and highly classified covering even outer garments such as sportswear like golfwear, woman's dress, and man' s suit. As fashion cycle is getting shorter and the more a nation advanced prefers knit to woven fabrics knit industry has a very bright prospect, particularly woman's knit which is sensitive to fashion can be said as a fashion product with high value added. This study is to grasp the physical properties of stitch which are fundamental to the development of knit products. For this purpose, 2/20s of 100% wool were woven by the author of this study to basic plain stitch, rib stitch, varied transfer stitch, and float stitch on a SEMASEIKI cross knitter 7G to test the physical properties, and the result was as follows; 1. As for the relation between knit stitch and rate of extension recovery, rate of extension recovery was higher in the course direction than in the wale direction of three stitches except transfer stitch; rib stitch showed the highest rate of extension recovery in the course direction while float stitch showed the highest rate of extension recovery in the wale direction. 2. As for the relation between knit stitch and bursting strength elastic rib stitch showed higher bursting strength to indicate elasticity is an important factor of bursting strength and float stitch showed higher bursting strength too to indicate that the floating yarn on the surface plays a role of support. 3. As for the relation between knit stitch and air permeability perforated transfer stitch showed the lowest air permeability to prove that the size of perforation affects on the air permeability a great deal. 4. As for the relation between knit stitch and warmth retaining rib stitch through two lined needle bar showed the highest degree. The reason the warmth of perforated transfer stitch didn't decrease much was because the perforation wasn't big enough and content of air increased from the unevenness of the perforated parts through stitch variation. Based upon this result, each stitch can be characteristically summarized as follows; plain stitch showed a stable condition of knit cloth in four kinds of physical property test. And rib stitch is proper to tighten the edge of sleeve or clothe making use of its excellent extension recovery and to make socks for the highest bursting strength and warmth retaining. In the case of transfer stitch, seasonable designs can be taken by controlling the size of loop. Considering the pleasantness, underwear should be made of stitches with good air permeability float stitch was revealed to have color and pattern effects and a great bursting strength. This study has limitations in the aspect that it dealed with a small part of various knit stitches and the items of physical property test were not enough. The author of this study hopes that further studies would make deeper understandings about knit stitch based on more varied stitches and physical property tests ultimately to contribute to the development of fashionable designs proper to maximize the usage, function and originality.

This study reviewed the planning characteristics of dormitories for secondary schools in the Japanese Colonial Era by analyzing the architectural drawings collected by the National Archives of Korea. The dormitory was one of the essential facilities in secondary schools but there have been few studies in this area. The analysis items were the site plan and the planning characteristics of student bedrooms, dining hall, and supervisor's area, which were the main elements of the dormitory. The results of this study were summarized as follows. 1) Generally, the dormitory area was placed in the rear of buildings for teaching with a close connection. 2) The student bedroom wings were laid out in parallel to the south as a rule making the typical site plan pattern for a dormitory, whereas the other parts of dormitory, such as the dining hall and supervisor's area were placed in the site conditions. 3) Generally, the unit plans of bedrooms for Korean schools were the ondol type and were small in size, whereas those for Japanese were the tatami type and large in size with separate study and sleeping areas. 4) The dining hall annex was made up of a dining hall and kitchen-bathroom area in general. For Japanese schools, the school store area was added to these areas. The typical shapes of dining hall plans were narrow and long with an adjacent corridor, so the overall plan of the dining hall annex was like that of a single-corridor type block plan. 5) The supervisor's area was a smaller part of the dormitory but it was considered to be a symbolic part of the whole dormitory in site planning and design.

We conducted a study to investigate milk and dairy products consumption among elementary school students to identify ways to increase their intake of milk and dairy products. We asked 518 students in Seoul to fill out questionnaire. Only 55.6% of the subjects consumed milk daily, and 43.7% of them drank at least 1 cup per day. The frequency and quantity of milk consumption were higher in male students than female students. The majority of the subjects consumed whole milk, and most students(59.5%) preferred flavored milk to whole milk. The reasons given for drinking milk included 'wanting to be tall'(66.1%) and 'for good health'(47.1%), while the main reason given for not drinking milk was stomach pain (68.4%). Records of having an unpleasant experience and upset stomach after drinking milk occurred at a higher rate for those who did not drink milk(84.2%) than for those who did(53.3%). Of the students questioned, 36.9% consumed dairy products other than milk 3~4 times per week, and liquid-type yoghurt(43.8%) and ice cream(35.4%) were the preferred dairy products among students. The reasons given for consuming dairy products were 'good taste'(56.6%), 'good to eat'(46.6%), 'wanting to be tall'(32.4%), and 'for good health' (25.4%). Among those students who did not consumed dairy products, the major reason given was 'family does not eat at home'(33.3%). After consuming the dairy products, 71.4% of participants thought that dairy products did not result in physical improvement. Most students had experienced purchasing milk and dairy products by themselves. When they bought milk or dairy products, the reasons given for making a particular selection were 'shelf-life'(61.6%) for milk, and 'favorite dairy products'(54.1%) for dairy products. According to participants, the factors that need to be considered for milk and dairy product consumption among elementary school students are 'higher nutrition' (60.8%), 'better sanitation'(57.3%), and 'better quality and taste'(55.2%).
