The study was conducted to evaluate the feasibility of Mozzarella cheese analogue generation by using a mixture of soy milk and raw milk and to compare the quality of the resultant cheese with that of Mozzarella cheese manufactured using the traditional method. The mixtures showed increase in protein and decrease in lactose and SNF in a dose-dependent manner with the addition of soy milk. The Mozzarella cheese analogue had lower total solids content than the control cheese product, while the fat content was similar between both. The analogue cheese had lower ash content than the traditionally prepared cheese; the content was proportional to the amount of soy milk in the mixture. Higher soy milk quantities within mixtures also resulted in proportionally higher levels of fat content within analogue cheese. Water-soluble nitrogen content was lower in the analogue cheese than in the control cheese. While the WSN level increased in the control cheese, it was almost constant in the analogue cheese. The control cheese had much higher actual and predicted yield than the analogue cheese, while the analogue cheese had a higher stability level. The control cheese had a higher transfer rate than the analogue cheese, with the exception of lactose. Electrophoresis analysis showed bands for Mozzarella cheese analogues that were present in addition to the normal ${\alpha}$-casein and ${\beta}$-casein bands. Physical characteristic analysis showed that hardness was affected by the addition of soy milk to cheese, while cohesiveness and brittleness were affected by the addition of raw milk, and elasticity was barely affected by milk composition. The meltability of the control cheese was higher than that of the analogue cheese and increased during 30 days of storage at $4^{\circ}C$. Browning, oiling-off, and stretching characteristics were almost identical between the 2 types of cheeses. Sensory evaluation findings showed that the control cheese had much better body texture, appearance, and flavor than the analogue cheese.

The purpose of this study is to analogize the appearance of Korean Ancient Architecture in view of the Stone Remains from 3 Kingdom Period to Unificated Shilla Period. But in these period, there is no building remains but some stupas and fine arts. Especially, there are many architectural appearance and revealing signature in these Historical Stone remains. Architectural elements which are analogized by stone remains what has value as historical materials by preservation of original form from 3 Kingdom Preiod to Unificated Shilla Period are as follows : 1) Platform, the representative characteristic of Korean traditional architecture, was frame structure and accumulate structure. And circular or square footing stood a same shape column on it is put on the platform. 2) In the case of column, there used entasis column and inclined column and circular chamfer technique was applied on the top side of it. Upper side of column, capital and head pentrating tie that small bearing block was put on the center of it was joined. And longitu야nal rest(長舌) supported a cross beam. Capital and small bearing block had no bottom heel, and heel side was curved and straight. Centered bracket structure was often used, and multi bracket structure is not used yet. Inward incline technique was used. 3) Inward opening pair door which had lintel, threshold, doorjamb was usually used, Fixing stone was used for structural safety, and circular handle and lock was used for decoration. Handrail was used on the edge of wooden floor for decorative effect and safety. 4) Square rafter and circular rafter were used in the same period and so did flying rafter. Double eaves and single eave were used in the same period but, single eave was usually used. In this period, square rafter was usually used. This would be studied more by comparing with Japanese wooden architecture. 5) Hipped roof was used and half-hipped roof was not used yet. In front of th hip, there are small sculpture called Jap-Sang(雜像), and windbell was hang on the end of the hip rafter. Concave roof tile, convex roof tile, round eaver tile, decorative tile at end of roof ridge were used. Lotus style was well used on the face of roof tile for decoration. From the results of this study, wooden architecture of Unificated Shilla period was simple compare to Koryo dynasty and Chosun dynasty but, it had some brilliant character. It was hard work that analogized the form of non-existent wood architecture of Ancient Korean period by restricted stone remains. But, in addition to the results of this study and research of old documentations, more study should be go on.

As we know, broadcasting implies a unilateral transmission by one sender to several recipients of information generally produced by third parties. Contrary to that, telecommunications implies an exchange between participants. Participants exchange information they produce during an interaction. However, in the age of convergence between telecommunication and broadcasting, it becomes difficult to determine exactly the boundary between services classified under telecommunications and those classified under broadcasting services. This means that new regulatory regime should be introduced to meet the convergence between telecommunication and broadcasting. In this article, we try to overcome the existing framework for understanding and regulating convergent services. In order to develop more powerful and useful framework for dealing with new convergent services, we focus on the original characteristic of "cast services," which could give us very significant basis for further discussion. "Cast services," such as traditional broadcasting services, have the characteristics of both public goods (non-exclusivity and non-rivalry in consumption) and non-interactivity. Depending on the existence of these three characteristics, we are able to apply different regulatory regime to those convergent services.

This study is on the costumes for Korean traditional play, Nong-ak(farm music), and intends to analyze their aesthetic features, laying emphasis on Pilbong Nong-ak, Im sil, Chollanam-do. About its origin there are many kinds of theories; for example, the theory of hoping stability, the theory of it being related with Buddhism, the theory of martial music, etc. Shamanic, Buddhist, and martical fators that support these theories are expressed through flags, bells, drums, Deograe (half-coats), Cheonrips (sang-mo, felf hats), go-kkals(peaked hats), colored lines called 'ga-sa', which are used in Nong-ak. The characteristic of the costumes used in Pilbong Nong-ak is that it keeps its conservativeness and the costumes of its members are various and splendid. For example, leader groups' black half coats, Changbu's and Hwa-dong's red and bule over coats are remarkable. Particpants wear gok-kal or cheonrip, trousers and half coats which are the basic costumes of Korean Hanbok, and wear blak half coats or blue vests and put blue, red, and yellow lines around them. The colors and knotting methods of those lines in this region are the same with those of chollawoo-do and Kyongi province, but different form those of Kongwon and Kyong-sang province using green, red, and yellow colors. This comparison of colors shows each region's preference of peculiar colors and those colors coincide with colors used in flags. The research on the aesthetic characteristics of Nong-ak clothes through each region's clothes tells us that these can be linear clothes which have expressiveness as stage clothes used in Madangori, the play which is performed in the field, and modern spatial formativeness. Those characteristics are as follows; 1. The expressions of a rhythmical and daring round line by turning a long line of sang-mo. 2. Various rhythms according to the attaching methods. 3. The expressions of thick, simple, and daring color lines. 4. Natural beauty of materials. 5. The popular simplicity and non-technicality 6. The beauty of five-direction colors, Oriental ideal colors Consequently in this study our national consciousness of beauty are examined through clothes. It is suggested that the aesthetic characteristics of Nong-ak clothes and ornaments should be effectively expressed, for this purpose. interests in participants' clothes should be increased in order to prevent the confusion of each region's features. Also it is necessary to improve color lines, their length, width, and knotting methods, and beautify instrument. Finally this study intends to bring the reappraisal about the art of Nong-ak clothes and its re-establishment in view of modern aesthetic consciousness.

Lespedeza cuneata G. Don is an edible perennial herb used in traditional Korean medicine. We investigated the anti-proliferative properties and mechanism of L. cuneata extract. The ethanolic extract of L. cuneata dose-and time-dependently inhibited human colorectal cancer cell proliferation. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay was used to test the effect of the extract on proliferation of HT-29 colorectal cancer cells. The extract inhibited HT-29 cell proliferation with an $IC_{50}$ value of $554.26{\pm}8.81{\mu}g/mL$. L. cuneata extract suppressed production of pro-inflammatory cytokines interleukin-6 and tumor necrosis $factor-{\alpha}$. Apoptosis was evaluated by analysis of DNA fragmentation, poly(ADP-ribose) polymerase cleavage, caspase-3 activity, and protein expression of pro-apoptotic (Bax) and anti-apoptotic (Bcl-2). Our results demonstrated that the extract induced DNA fragmentation and characteristic morphological changes associated with apoptosis in HT-29 colorectal cancer cells. The extract also time- and dose-dependently up-regulated expression of the Bax and down-regulated expression of the Bcl-2. Furthermore, the extract dose- and time-dependently enhanced caspase-3 activity. Our findings provide evidence that L. cuneata extract may mediate its anti-proliferative effect via modulation of apoptosis.

The present paper suggests the original form of the bell pavilion for the King Song-Dok bell which is one of the precious national treasure of Korea. In order to this, many literatures were reviewed including both historical and acoustical references. As the results, the model of the bell pavilion for the King Song-Dok bell is suggested as follows considering acoustical characteristics of the King Song-Dok bell and the traditional Korean bells ; 1) The bell pavilion has the rumbling puddle beneath the bell on the ground floor for resonance of sound 2) Many lumbers are used for columns and beams rather than boards since natural frequencies of the bell are 64 Hz and 168 Hz so that the sound absorption of the low frequency sound may not be occurred. 3) Only some boards may be used for the area between upper and middle molding of lintel in order to prevent of direct sunlight and sea breeze since this type of structure were used for bell pavilion of the same age. 4) Square form with the odd number of 3 or 5 Kans is adopted for bell pavilion considering the weight and the size of the bell which had been used traditionally 5) Finally, half-hipped structure is used for the roof of the bell pavilion which was the predominant form of the age.

Urban runoff models have been continuously developing with concerns for urban flood. Recently, models that be able to quantitatively analyze surface inundation caused by overflowed water from storm sewer were also developed by coupling 1-dimensional sewer model and 2-dimensional surface flow model. However, only overflowed water from storm sewer can be analyzed by the models have been developed until now. They are limited to be not able to analyze surface inundation caused by surface runoff that could not flow into the storm sewer. In order to overcome the limitation, basin-overlap method was devised adding a dummy 1-dimensional sewer layer to the model, so it can consider the efficiency of inflow to the storm sewer system. XP-SWMM 2011 is applied for urban runoff model and the flood event occurred on July 27, 2011 in basin-shaped Sadangcheon watershed is chosen for study inundation event. According to simulation results basin-overlap method reappear the observed inundation event more precisely than traditional method. This results suggest that drainage system has to be improved for reducing inundation caused by surface runoff and would be used as considerations for planning an urban basin design magnitude.

The result of studying papers about management of lower back pain published in domestic and foreign nursing and medical magazines in these 10 years is as follows ; 1. General characteristic of lower back pain ; 1) In sex distribution, there were more men than women in 5 papers and more women than men in 4 papers among 9 papers surveryed. 2) In age distribution, thirties to forties of patients had more lower back pain as surveyed by general hospitals and fifties to sixties of patients had more lower back pain as surveyed by oriental medical hospitals. 3) In cause factor, there were 50 to 65% of sprain, 32 to 44% of herniated intervertebral disc and 13 to 29% of degenerative changes. 4) In symtom distribution, there were 26 to 57% of lower back pain, 42 to 65% of lower back pain with radiating pain and 34 to 99% of paravertevral muscle spasm. 5) In period of pain management distribution, 18 to 40% of patients experienced pain for less than 6 months and 59 to 82% of them experienced pain for more than 6 months in 3 papers among 4 papers. 6) In surveying the treatment, 66 to 88% of patients had conservative treatment and there were treatments of general hospital, oriental medicine, self remedy and traditional practice in conservative treatment. 7) In job distribution, 12 to 50% of them were housekeepers, 23 to 31% office workers, 4.6 to 36% blue color workers and 11 to 15% students. 2. As psychological character lower back pain paients had anxiety, depression, anger-hostility, phobic anxiety, neurasthenia, hypochondriasis, and interpersonal sensitivity. 3. To distinguish the cause of lower back pain, plain lumbar roentgenogram, straight leg rasing test, eletromyelogic findings, somatosensory evoked potentials CT and MRI were performed. 4. To relieve lower back pain. epidural adhesiolysis, epidulal injection of local anesthetic in mixture with steroid, lumbar spinal root block, low level laser therapy, acupuncture like transcutaneous nerve stimulation(AL TENS), topical capsaicin and lumbar orthotics were used in medical field, and relaxation technique was used in nursing field. 5. Mckenzie's extension exercise and William's flexsion exercise for lower back pain were used in medical field and Yoga exercise was applied in nursing field. 6. The more school education and self efficacy were high, the better they had active coping lower back pain positively and the less self efficacy was the more they had serious pain. As a result of studying the paper there have been very little research for lower back pain in nursing fields of Korea and foreign countries. Because 60 to 80% of population expeience lower back pain at least more than once, it is necessary to develop the study and clinical practice for management of lower back pain.

Differences in competitive characteristics for mineral nutrition were compared with rice and weeds according to rice planting types like the traditional hand transplanting, machine transplanting of young(10days old) and mature(30days old) seedling, flood direct seeding of germinated seeds and dry direct seeding of dry seeds. There was a slight competition for such nutrients as N, P, K, Ca, and Mg by E. crus-galli and E. kuroguwai in transplanting cultivations. However, nutrient uptake by rice in direct-seedings was severely inhibited throughout the whole growth period by the two weeds including annual weeds such as S. Juncoides and C. difformis. The competition for nutrients at different cultivation types was mainly governed by the dominant weeds.

Lentils (Lens culinaris) are a nutritious and popular food throughout the world. This review provides an overview of the nutritional and functional properties of lentils. Lentils have high nutritional value: high protein, high fiber, low fat, and a variety of minerals. The addition of lentils to other foods could enhance their health benefits. Additionally, there is no decrease in the amino acid content in lentils when cooked; rather, the amino acids increased and the phytic acids decreased. Lentils are generally known to have biomedical functions including antioxidative, anti-cancer, anti-inflammatory, antihypertensive, and thrombolytic properties. The data presented here show that fermentation would increase the amount of bioactive substances in the beans. Therefore, fermentation techniques could be a new approach to produce lentil-based foods. They are also eco-friendly, cost-effective, and feasible processes. This review has suggested a future development of new lentil-related foods using traditional fermentation technology.
