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.

We report new polymer stabilized ferroelectric liquid crystal (PSFLC) cells with mechanical stability which is achievable by introducing photospacers in the cells. It was found that the mechanical st ability of the PSFLC cell was effected by introduction of photo spacers. We analyzed the dependence of mechanical stability and memory property on the density of photospacers in the PSFLC cell. The stability and memory properties of PSFLC Cells depending on photospacer density are discussed. 1. Introduction Recently, flexible displays have attracted much attention because they have remarkable advantages: thinner, lighter, non-breakable and conformable features. Flexible displays have various potential applications such as e-book and e-paper displays utilizing the distinct features. E-book and E-paper displays demand very low power consumption, so that bistable memory liquid crystal modes are required in case of flexible plastic LCDs for those application. Three kinds of memory LC modes have been developed; bistable nematic, bistable cholesteric and bistable FLC. Among them SSFLC as one of bistable FLC has big advantages such as low driving voltage, wide view angle and fast response time, SSFLC cells are, however, very weak against mechanical shock. Polymer stabilized FLC (PSFLC) has been developed to overcome the poor mechanical stability of SSFLC. PSFLC was known to have network structure that FLCs are oriented with smectic layer ordering in polymer network. The polymer network stabilizes the FLC orientation, which leads to improvement of mechanical stability of PSFLCD. A lot of studies have been done for the application of PSFLC to flexible $LCDs.^{[1{\sim}12]}$ However, it should be noted that PSFLC does not have sufficient mechanical stability for the particular applications such as smart card LCD, where LCD is highly bendable.Bead spacer was mainly used to maintain cell gap of conventional PSFLCDs. But the spacer density of it is not locally uniform in the cell, so that it is generally difficult that the PSFLCDs with bead spacers show sufficient mechanical stability. In order to more improve the mechanical stability of PSFLCDs, we introduced photospacers into PSFLCDs. In this paper, we describe the improvement of mechanical stability by introducing photospacers into PSFLCDs.

In order to develop and propagate the low sodium kimchi for preventing high sodium related diseases, the salinity, pH and acidity of cabbage(Bachu) kimchi sampled from home located in 6 big cities(Pusan, Daegoo, Kyungjoo, Daegoo, Jeonjoo, Daejeon, and Seoul) and commercial 6 manufacturers(A~F) distributed in markets were monitored and analyzed in the current study. Salinity was significantly (p<0.05) higher in homemade($3.03%{\pm}0.60$: 1.79~4.40) kimchi than in commercial($2.38%{\pm}0.60$:1.04~2.87) kimchi. Also, salinity was significantly(p<0.05) higher in Pusan($3.45{\pm}0.60%$) kimchi than in Kyungjoo($3.11{\pm}0.39$), Daegoo($3.19{\pm}0.42$), Jeonjoo($2.98{\pm}0.32$), Daejeon($3.00{\pm}0.38$) and Seoul ($2.52{\pm}0.46%$) kimchi. However, there was no significant difference(p<0.05) of salinity in 6 kinds of commercial kimchi. Related to this result, pH of kimchi from homemade and commercial was $4.40{\pm}0.29$(3.72~6.03) and $5.45{\pm}0.76$ (4.23~6.35), acidity of kimchi from homemade and commercial were $0.99{\pm}0.30%$(0.28~2.17) and $0.45{\pm}023$(0.17~0.93), respectively. Thus, the current study provides evidence that we may need to manufacture the low sodium kimchi because all homemade kimchi, especially Pusan and Daegoo kimchi and commercial brand kimchi contained over 2% salinity.

Three kinds of model melanoidins adjusted to have the same brown color intensity were made from glucose-glycine, glucose-lysine, xylose-arginine and their antioxidative properties were determined. The antioxidative activities of these model melanoidins in linoleic acid emulsion system were determined by ferric thiocyanate method, conjugated diene contents, peroxide value and electron donating ability by DPPH. Xylose-arginine melanoidin showed the strongest antioxidative activity and electron donating ability. The antioxidative effect of melanoidin could be reliably predicted by determining peroxide value and DPPH method. Each melanoidin was separated on Sephadex G-50 column, and brown color intensity, reducing power, ninhydrin positive reaction and antioxidative activity of each fraction were determined. The antioxidative activities of melanoidin fractions showed strong correlation with their brown color intensity and especially to their reducing power. In spite of same brown color intensity, there is no big differences between these model melanoidins, thus xylose-arginine showing strongest antioxidative activity followed by glucose-lysine and glucose-glycine melanoidin. Xylose-arginine melanoidin also showed the strongest electron donating activity and broad range of reducing power when fractionated on Sephadex G-50, which was different tendency from the other model melanoidin.

The national land use plan that targets the whole national land and all kinds of urban plans that targets a city or a part of city must be performed continuously now and after that. Therefore, the importance of land use plan, that is included in those plans, is very big and crucial. This study scrutinizes the detail zoning land suitability analysis which bases on urban basis plan and the GSIS application plan about allocation, applied various basic theory which is arranged in that course to study area, and try to develop the land use suitability analysis system, a application system The programing language used in system development is the AML of ARC/INFO. On this study, the results divide into four parts. First, we develop the land use suitability analysis system and can simplify and automatize a complicated analysis course and this system will be more useful to the land use suitability analysis. Second, the analysis range is expanded, considering the circumstance environmental factor of planning area outside. So we can implement more comprehensive analysis. Third, we apply a precedency conception and a legal restrictive element that base on urban characteristics and urban space structure theory to this study, develop a computerized method about distributive method, and can allocate the detail zone in the various ways. Finally, the next studies that can clear the detail zone suitability criteria and the correlation of the relationship of materials are essential to improve the accuracy and confidence in this analysis.

This thesis is a study on the oldest feng-shui book "Janggyeong(葬經)". Specially, it is a focus on the feng-shui orientation method so called Sasepalryongbub(四勢八龍法) in that book. This method is to identify fortune and misfortune with the directions to be measured by a feng-shui compass. Sa(四) of Sase(四勢) is the four pieces of direction of dividing 12 parts for 360 degree circle. To divide for 12 parts is related with 12-Jiji(地支). Sa mean In(寅), Sin(申), Sa(巳), and Hae(亥). Se of Sase means a large stem of mountain. Generally, Sase are the big mountain stems of the four directions as In, Sin, Sa, and Hae. Pal(八) of Palryong(八龍) mean the 8 parts of equal division for 360 degree. It is related with Palgoe(八卦) that divide for 8 parts equally. Palgoe are Jin(震), Li(離), Gam(坎), Tae(兌), Geon(乾), Gon(坤), Gan(艮), and Son(巽). Ryong(龍) of Palryong(八龍) is a stem of mountain that is measured with 8 parts of equal division feng-shui compass. Sasepalryongbub make a connection between Sase and Palryong. When they are connected, it is a good fortune like as In(寅) and Li(離), Sin(申) and Gam(坎) or Gon(坤) or Gan(艮), Sa(巳) and Tae(兌) or Geon(乾), Hae(亥) and Jin(辰) or Son(巽). It is based on two theories. The one is 12-Unseongron(運星論), the other is one of Ohaengron(五行論) as Samhap-Ohaeng(三合五行). 12-Unseongron begins from dividing all human life affairs with 12 steps. Saeng(生), Wang(旺), Myo(墓) are the very important things among 12 steps. Saeng means starting, Wang means flourishing, Myo means keeping. Samhap-Ohaeng is made with Jiji of Saeng, Wang and Myo steps about 12-Unseongron. Saeng is the most important thing among of Saeng, Wang and Myo in Sasepalryongbub which means birth. Saeng of Jiji direction can help Palgoe direction as a counterpart. Like this, the good relation of Sase and Palryong is that Jiji direction can help Palgoe direction. For example, there are In(寅) of Jiji and Li(離) of Palgoe, can be explained as these kinds of the good relations. In view of Samhap-Ohaeng, In of Jiji is regared as Saeng of fire(火). This fire- Saeng-In as Jiji can help fire- Li as Palgoe. It can be said as a good condition that Sase and Palryong be connected like this case. This is the main content of Sasepalryongbub as being treated in this study.

Association rule of data mining techniques is the method to quantify the relevance between a set of items in a big database, andhas been applied in various fields like manufacturing industry, shopping mall, healthcare, insurance, and education. Philosophers of science have proposed interestingness measures for various kinds of patterns, analyzed their theoretical properties, evaluated them empirically, and suggested strategies to select appropriate measures for particular domains and requirements. Such interestingness measures are divided into objective, subjective, and semantic measures. Objective measures are based on data used in the discovery process and are typically motivated by statistical considerations. Subjective measures take into account not only the data but also the knowledge and interests of users who examine the pattern, while semantic measures additionally take into account utility and actionability. In a very different context, researchers have devoted a lot of attention to measures of confirmation or evidential support. The focus in this paper was on asymmetric confirmation measures, and we compared confirmation measures with basic association thresholds using some simulation data. As the result, we could distinguish the direction of association rule by confirmation measures, and interpret degree of association operationally by them. Futhermore, the result showed that the measure by Rips and that by Kemeny and Oppenheim were better than other confirmation measures.

This study aims to classify the biotope types and evaluate its functions for acquiring the basic information which can support the landscape ecological management of the urban forest in the case of the three parks in Daegu metropolitan city and then to analyze vegetation landscape patterns. The biotope classification was mostly divided into 5 to 6 biotope type groups in the high units and 15 to 20 biotope types belong to them and then could know that the more big the park size, the more diverse and large the biotope types and its average area. The biotope grade over the three parks was dominating low rank grade (1 to 3 grade) 72.7% that forest organism is inadequate as live, and high grade (7 to 9 grade) did not appear entirely. Most in Biotope function estimation were appeared less than the middle rank grade and biotope area is bigger, those grade rises and temperature could know that is fallen. Vegetation landscape patterns was very simple because only two kinds of Robinia pseudo-acacia and Quercus acutissima is appeared as the dominated landscape elements in all of the three parks. And also because average area of those elements is generally 1ha or so, there was much problems in consecutiveness of functional role as forest ecosystem component. Conclusively, Ecological landscape management need to improve Biotope diversity and functionality, and it secures ecological minimal area and space linkage.

We conducted a consensual, expansive, and successive study to compare cultural differences and similarities between Korean, Chinese and Japanese's Seasonal Festivals and Foods documentarily. It showed interesting results that the three countries had celebrated with similar meanings, and shared similar events and special foods. Seasonal Festivals happen throughout the year sequentially: the New Year Day, January $15^{th}$(first full moon festival), March $3^{rd}$(double three day), May $5^{th}$(double five day), July $7^{th}$(double seven day) and finally the Year Farewell Festival. While, the festival of a royal birthday of Buddha happens on April $8^{th}$ in both countries: Korea and Japan. There is also one of the big festivals called the harvest moon festival on August $15^{th}$, and this event celebrates with special foods both in Korea and China. On December $23^{th}$, it is a special day for both Chinese and Japanese, but they celebrate the day with different meanings to it. Three countries have a special seasonal event celebrated each other. Koreans have a special event called Sambok to overcome summer with special food during a middle of June to the beginning of July. Chinese have a special event for overcoming winter with soup on December $8^{th}$. Japanese have a special event with rice cake to safety on January $11^{th}$. On these seasonal festivals, it is different to note that two different kinds of calendars are used. The lunar calendar is used by Koreans and Chinese whereas the solar calendar is used by Japanese. Because of the similarity in Buddhism, and agricultural industry, and especially sharing Chinese Characters in words, these three countries have in common in many ways to celebrate Seasonal Festival, and it is very unique custom in the world. Nowadays; however, these traditional events and special foods are changing in more simplified version and almost disappearing in all three countries. Therefore, we suggest that the Seasonal Festivals and Foods should be more emphasized in flourishing and exchanging between Korea, China and Japan.

The followings are concluded from the treatment of headache in Hyungsang medicine, focussed on 11 kinds of headaches in Donguibogam. Headache is classified into overall headache and migraine according to the affected region. The causes are divided into exogenous affection and internal injury; The former brings on headache due to Wind-Cold and headache due to Damp-Heat. The latter, reversal headache, headache due to adverse rising of phlegm, headache due to regurgitation of Gi, headache due to excessive Heat, headache due to excessive Damp, true headache, and alcoholic headache. Headache due to internal injury generally tends to show deficiency syndrome with external affection. Headache due to exogenous affections is common to those who have big head or white skin and to Bangkwang type, and woman. The primary causes are Wind-Cold and Wind-Heat. When the body is observed in the perspective of eight phases, Damp-Heat is to be produced in the front, and Dry-Damp, in the back. Headache due to Damp-Heat is susceptible to Yangmyeong meridian type whose body develops more in the front and to woman. In the perspective of the upper and the lower, Yangdu(that is, head) is related to Eumdu(that is, glans of penis). Headache is also caused by the problems of Eumdu ,such as deficiency of Essence in man, pathologic change of uterus in women, and San syndrome in lower abdomen. In the case of man, headache is frequently severe and difficult to treat because head is a root for man. Disharmony of Gi and blood between the right and the left brings out migraine and headache due to regurgitation of Gi. Migraine is usually accompanied by symptoms of exogenous affection and often afflicts Gi-type, Shin-type, Soyang meridian type, deer type, and Dam-type. Headache due to regurgitation of Gi is brought by Gi deficiency or blood deficiency so that symptoms of exogenous affection do not show. It is mainly common with old people and those who have sunken eyes induced by deficiency of stomach Gi. In the perspective of the upper, the middle, and the lower, the pathologic change of head, chest and abdomen also bring about headache. The pathologic cause of head is Wind-Heat ,which triggers overall headache, migraine, headache due to Wind-Cold, headache due to excessive Heat, The pathogen of chest is phlegm-Fire and brings out headache due to Damp-Heat and headache due to adverse rising of phlegm. The pathologic factor in abdomen is Cold-Damp and produces headache due to adverse rising of phlegm and headache due to excessive Damp. In case of women, headache is generally caused by phlegm-Fire and retention of undigested food.
