The purpose of this study is to examine consumers' recognition, purchase intention, price acceptability of carving decoration, which can be said to be one part of food-space presentation, food styling, and table decoration. For this, a survey was carried out to target adults in over 20 years old who use a bus and a subway during morning and evening time in Daegu area from May 18, 2009 to May 22, 2009, and 296 copies were used for the final analysis. As a result of the research, over 50% of the consumers know about carving, saying they have come to mow it mostly through TV. Carving was mentioned to be probably used the most in buffet restaurants and other types of restaurants, and to be likely to be used the most in buffet restaurants and Japanese-style food Also, they responded that flower-butterfly carving & Japanese-style food, animal-form carving & Chinese-style food, and watermelon carving & buffet are harmonized the most. In addition, consumers with high recognition of carving decoration were indicated to be high in purchase intention and price acceptability. Also, Consumers with low recognition of carving decoration perceive very low price acceptability even if being high in purchase intention. However, when purchase intention of consumers with high recognition of carving decoration was high, price acceptability was indicted very highly.

We analyzed 57 types of herbal medicines for Soeumin, clinically applied in Dongyisoosebowon. In order co discover the standard of herbal classification for the Sasang Constitutions, four concepts of Sasang Medicine were applied. These included 'Sadangron (theory of four groups)', 'Seungganggaehap(ascending-descending and gathering-dispersing)', 'Pyorihanyoul(exterior-interior and hot-cold)', and 'Hyungchiaekmi(fragrance, smell, bodily fluid and taste)'. According to these analyzing methods of herbal properties, we have reached the following conclusions: 1. Lee Je-ma first established the physiology of the internal organs of the Sasang Constitutions through the understanding of constitutional pathology. Dr. Lee then classified herbal medicines into four constitutional groups by observing the herbal effects according to such perspective of organ physiology and pathology. 2. Among the Sasang concepts applied in the analysis of herbal properties based on the physiology and pathology of Sasang constitutions, 'Seungganggaehap (ascending-descending and gathering-dispersing)' was found to be the most useful. Meanwhile, 'Sadangron, (the theory of four groups - Spirit, Qi, Blood and Essence),' along with 'Pyorihanyoul (exterior-interior and hot-cold)' and 'Hyungchiaekmi (fragrance, smell, bodily fluid and taste)' were partially useful. 3. Herbal medicines for Soeumin are characterized by ascending energetics that protect the Yang Qi. The 'Exterior heat disease' is treated with herbal medicines that raise the "Exterior Yang" in three different way: by tonifying Qi. by tonifying Blood and by releasing exterior. The 'Interior cold disease' is treated with herbal medicines that descend "Interior Yin" in two ways. One by warming the stomach, and the other by regulating Qi. 4. Cases where a whole category of herbs with the same effect have been applied co one constitution, are most frequent among Shaoyin herbs. There was an intimate connection between the treatment methods and the traditional effects of herbs for 'Soewnin'. These discoveries allowed us to see that the development of the pharmacology of the Sasang Constitutional pathology more progressed in 'Soeumin'. *analysing simple herbs of "DongEuiBoGam JangBu" we compare JangBu of traditional oriental medicine with JangBu of Sasang Constitutional Medicine. So we can comprehend the JangBu's difference of traditional-oriental with sasang-constitional medicine.

The Russo-Japanese War(1904-1905) in the early 20th century greatly influenced the international politics in Northeast Asia and the destiny of both countries. There are many studies on the cause of the outbreak and its effect on the Korean peninsula. The victory and defeat of the battle of Tsushima also the subject of research by renowned scholars and navy officers. Many previous studies have analyzed the process of engagement. However, There was a lack of research that analyzed at the tactical level of naval commanders. Therefore, this study tries to review the battle of Tsushima in terms of tactical level, that is formation, maneuvering, damage control. Naval operations at sea with many variables are not always done as planned. The intuitive judgement and readiness have had a decisive impact on victory and defeat. The analysis of the naval warfare on the basis of formation, maneuvering, and damage control makes the cause of the win more clearly. The conclusion of the this study can be summarized in five ways. First, victory would be achieved through the suppression of the beginning. The destiny of the Tsushima battle was determined by an 1 hour after first firing. The Japanese fleet caught fire by paralyzing the command and control capabilities of the Russian fleet. Second, the Japanese fleet's power was superior to the Russian fleet. In general, Japan and Russia had similar powers, and Admiral Togo's "T crossing tactics" decisively contributed the victory. However, when compared to the weapon system level, formation and maneuvering, Japan was much more dominant. Third, people realized that one side to be annihilated in the battle between similar powers after the Tsushima battle. The common perception before the Battle of Tsushima was that the battle ship would not sunken, and that the result of wiping out was difficult. However, there is s time for one sided victory and defeat depending on the early suppression nad the destruction of the command and control ability. Fourth, it is the importance of damage control ability. The main cause of the Russian fleet's loss of command and control ability was thick smoke from fire, and maneuverability was greatly deteriorated due to coal overload. In this way, importance is still valid after more than 100 tears. Fifth, the area of uncertainty. In the navy battles, one or two shots of clear firing in the beginning and small misconception and minor mistakes decide win or loss. Ultimately, this area of fortune can be linked to mindset of the commander. I hope this research will be help to naval researchers and naval commanders at the sea.

This study investigated the effects of vitamin C supplementation on the nutritional iron status of 31 adolescent girls, aged 12-15 years, with low hemoglobin levels. They were randomly divided into four groups, and for two groups daily150mg or 900mg of L-ascorbic acid(AsA) was given in three equal doses at three meals during 9 weeks. To another group daily 60mg iron as ferrous sulfate was given in the same way as AsA. The control group was given sugar placebo. Body iron status was monitored through the determination of Hb, Hct, MCHC, and serum ferritin concentrations. Dietary AsA and iron intakes were measured from food consumption surveys performed by 3-day 24-hour recalls. The amount of absorbed iron was estimated from the model of Monsen et al. The average amounts of food iron for four groups were 12.3- 15.0mg and 11.1 - 18.9mg at initial and at final period of the supplementation trial, respectively. The tentatively estimated amount of absorbed iron was significantly increased in the 900mg AsA and iron supplementing groups, but not in the 150mg AsA and placebo groups. Both Hb and MCHC were improved to above normal levels in all groups except the placebo group. Hct was elevated only in the AsA 900mg group whose Hct was relatively lower than the other groups. Serum ferritin concentrations of the four groups, which were as low as 8.50 - 14.39ng/mL on average at the intial periods, augmented significantly to 20.18ng/mL and 26.63ng/mL in the 900mg AsA and iron groups, respectively. Serum ferritin was not elevated in either the AsA 300mg group or the placebo group. The above data indicated that the daily supplementaion of 150mg AsA to the meals containing 12-15mg iron per day promoted Hb levels of adolescent girls with low Hb, and the 900mg AsA supplementing improved not only Hb level but also body iron store. A supplementation of 60mg iron per day appeared to be slightly more effective in improving the iron status in comparison to the 900mg AsA supplement.

Radio-based train control system has driving headway shortening effect by real-time train interval control using two-way radio communication between onboard and wayside systems, and reduces facility investment because it does not require any track-circuit. Automatic train protection(ATP), the most significant part of the radio-based train control system, makes sure a safe distance between preceding and following trains, based on real-time train location tracing. In this paper, we propose the overall ATP train interval control algorithm to control the safe interval between trains, and preprocessing-based speed profile calculation algorithm to improve the processing speed of the ATP. The proposed speed profile calculation algorithm calculates the permanent speed limit for track and train in advance and uses as the most restrictive speed profile. If the temporary speed limit is generated for a particular track section, it reflects the temporary speed limit to pre-calculated speed profile and improves calculation performance by updating the speed profile for the corresponding track section. To evaluate the performance of the proposed speed profile calculation algorithm, we analyze the proposed algorithm with O-notation and we can find that it is possible to improve the time complexity than the existing one. To verify the proposed ATP train interval control algorithm, we build the train interval control simulator. The experimental results show the safe train interval control is carried out in a variety of operating conditions.

Insomuch as it is important to manage water quality, from the perspective of water management, it is essential to understand the effect of the weirs on water quality and phytoplankton dynamics in various regions. The purpose of this study is to investigate the characteristics of nitro-nutrients, as well as occurrences and succession patterns of phytoplankton, in the river sections of the two weirs in the Yeongsan River for the five years (from 2012 to 2016) after the weir construction. In respect to this data, the average water temperature measured at the representative point in the section of the Seungchon Weir ($17.1^{\circ}C$) was higher than that of the Juksan Weir ($16.6^{\circ}C$) by comparison. By way of an analysis of this data, it was found that the water quality variables such as, organic matter, nitrogen nutrients and phosphorus nutrients were improved gradually during the period, but the degree of the improvement differs as noted and measured between the weirs. Under the circumstances, it is especially noted that the $NH_3-N$ concentration was higher for the point of the Seungchon Weir (2.204 mg/L) than that of the Juksan Weir (1.157 mg/L). This indicates that effluent as seen from sewage treatment plants and hydrological feature near the densely population area, could be the main cause for the incidence of water pollution in the upstream section of the Seungchon Weir. Additionally, the phytoplankton analysis showed that a relative abundance of diatoms and green algae were 56.9 % and 25.8 % respectively. However, it is noted that the cyanobacteria was measured lower as 10.7 %. Also, in the study sites cell density and occurrence frequency of cyanobacteria were relatively lower than compared to the same measurements noted in other rivers.

The purpose of this study was to evaluate color change and enamel surface changes using the plasma arc light source during tooth bleaching treatments. Twenty-four extracted bovine incisors were selected and embedded in the resin blocks. All the specimens were highly polished and discolored with commercial $COCK^{(R)}$. High concentration carbamide peroxide with and without plasma arc were used for bleaching. Specimens were bleached for 1 hour per week during 3 weeks. Color and enamel surface changes were determined with colorimeter (TC-8600A), microhardness tester(MXT-a7), scanning electron microscope(S-4200). All the collected data analyzed with paired t-test, t-test and one-way ANOVA. After the bleaching, both groups showed the color changes(${\Delta}E^*$). Microhardness of two group decreased after tooth bleaching. The SEM evaluation of enamel surface of both group showed a similar morphology of decalcification after tooth bleaching. Office bleaching using the plasma arc application with 35% carbamide peroxide can increase the color change. Office bleaching using the high concentration of carbamide peroxide and plasma arc also detract the outer surface of enamel. It is recommended that careful procedures are needed during office bleaching with high concentration of carbamide peroxide and light source.

The Reformation seems to have nothing to do with modern philosophy, but in reality closely related to it. From a philosophical point of view, the Reformation had a profound effect on the formation of modern philosophy in two respects. Voluntarism, asserting the predominance of divine will over divine reason, which is the basic principle of the Reformation, allowed an arbitrary interpretation of the Bible by ignoring the tradition of the Church and emphasizing 'Sola Fide'. As a result, the severe religious disputes arose and the modern intellectuals sought a deism and natural religion as an universal religion which is expected to put an end to religious conflicts. Moreover, voluntarism changed the way of inquiring nature from the speculative to the experimental based on observation and experiment, and provided the clues of the birth of experimental philosophy (empiricism) which is the experimental inquiry of human nature. In short, the Reformation brings about the search for universal religion on the one hand, but on the other the advent of experimental philosophy. Universal religion is not a mystic religion on which the religious behaviors and practices are based but just a world view that is the basis for scientific inquiry, and it was nothing but a philosophy for science. And also the experimental philosophy was a philosophy by science in that it is a science of human nature through experiment and observation, After all, the Reformation expelled religion from the main living room of philosophy and placed science on the spot instead.

The studies related to the price of artworks have focused on how factors that are determined on production level, such as artists and the artwork materials of the studies, affect the artwork prices. As 'Dansekhwa' is in the spotlight within local Korean art auction matket, this study would like to analyze the trend of the price changes of 'Dansekhwa' with its growing popularity among the public. We have estimated the price changes based on 4,199 auction data of 20 artists with top 20 auction prices selected by the Korean Art Price Appraisal Association, between 2005 and 2016. Also, in order to compare and analyze the price changes of the 'Dansekhwa' products, we have classified the 20 artists into groups of Dansekhwa and non-Dansekhwa. Starting from 2013, when Dansekhwa has first appeared, we applied the Difference in the Difference model(DiD) to estimate the result. As a result, the difference between two groups showed 71% of price difference due to the increase in popularity of Dansekhwa. This result proves that recognition level has an important role for increase in price of an artwork. Moreover, the fact that the formalized style of Dansekhwa has linked to the appreciation of the price means that production of information could play an essential role in growth of art market. As recognition level of Korean artists and their artworks is considerably low within the local art market, putting in the effort to increase the popularity of artworks among the public might be a helpful way to magnify the potential demand.

Objectives : Atopic dermatitis(AD) is a chronic recurrent skin disease which usually developed in infancy or childhood. AD often repeat improvement and relapse. The cause of AD is so indefinite that many methods of therapies(moisturizer, steroid ointment, antihistamine, immunomodulator, immunosuppressant, herbal medicine, alternative medicine, etc.) are tried. Recently, a lot of studies were made. But there is no report about the effect of Samulsopungeum(SM) and Prednisolone(PN) on AD. So, author aimed to investigate the effects of SM and PN on AD of NC/Nga mice. Methods : Thirty two mice(8 Balb/c mice and 24 NC.Nga mice) were divided into four groups; Balb/c mice was normal group. NC/Nga mice were divide into three group : control, PN, SM group. AD was induced in the control, PN, SM group by spreading DNCB. Then normal saline, PN and SM were orally administered three times in a week for 8 weeks to the control, PN, SM group, respectively. We observed changes of clinical skin severity score, serum IgE, IgG1, IFN-$\gamma$, IL-2, IL-4, IL-5, IL-10, IL-13, and so on. We used one-way ANOVA test statistically(p<0.01). Results : The clinical skin severity scores of PN group and SM group in 8th week were decreased compared to the control group. Serum IgE, IgGl levels of PN group and SM group were significantly decreased compared to the control group. Serum IFN-$\gamma$ in SM group was significantly increased compared to the control group. But, Serum IFN-$\gamma$ in PN group was significantly decreased compared to the control group. Serum IL-10 levels of PN group and SM group were significantly decreased compared to the control group. Serum IL-2, IL-4, IL-5, IL-13 levels of PN group and SM group were significantly decreased compared to the control group. mRNA expression levels of IL-2, IL-4, IL-5, IL-13 in the dorsal skin tissues of PN group and SM group were significantly decreased compared to the control group. According to biopsy reports of the ear and skin tissues showed that the tissue damage of PN group and SM group were highly reduced compared to the control group. Creatinine, BUN, ALT, AST levels of PN group and SM group were normal. Conclusion : According to the above results, it is considered that SM is effective treatment for the AD.
