Currently, we have seen sudden increase of demand for emergency medical services by reason for high-speed economic development increase of traffics, etc. in this society. Consequently the government enforced & operated emergency medical system in 1991 as a link of more positive countermeasure against it, but many problem; still remain in reality. In particular, the regional emergency medical center designated by the Ministry of Health and Welfare falls short of our expectations for its essential role by the reason of such as insufficiency in professional manpower and institutions concerned in small-scale hospital, matters with transportation system, preference of large hospital, etc. Therefore, this study was conducted grasp for the actual conditions of emergency medical system based upon literature research & the preceding studies and interview research the motive of coming hospital, satisfaction & understand to the subject of 150 persons of patients and their guardians who used regional emergency center of Pusan National University Hospital, thereby examining & analysing the cause of emergency room overcrowding by non-emergency cases, one of the problem; enumerated from preceding studies. The main result of this study is as follows. First the actual condition of non-emergency patients coming hospital for examining overcrowding of emergency medical center showed that, of the patients who used the emergency medical center, non-emergency patients accounted for 49.3%, which acted as the main cause of delaying medical care for emergency cases, cases of which medical person or first-aid man decided to come hospital accounted for 36.1 %, thereby suggesting essential need for re-education & wide public information to even the professional manpower besides patients & guardians for their using emergency medical system. Second, as the result of researching patient acknowledgement with reference to their using emergency medical center, the rate of their giving right answer is no more than 60%, which means that non-emergency cases' using as such is due to the shortage of their knowledge of the said emergency medical center, which suggests us that wider P.R for emergency medical system to common people who may be one of the patients of it at any time is still in need. Third, the result of researching for finding out a future remedy of emergency medical system showed that the users who know well of the way of using emergency medical center had relatively high satisfaction of it, ones who have lesser knowledge of it lower satisfaction and users who feel in need of emergency specialized manpower feel the necessity of public information of emergency medical information center(1339) at the same time. The finding of examining the subject of study, in conclusion, showed that the degree of the patients & their guardians' understanding of emergency medical system is lower and the medical persons concerned also had no distinct difference in their understanding of it from the common people's, which suggests us for extensive enforcement of systematic education and public information in aspect of the government via various media for the purpose of effective operation of emergency medical center.
The tube agglutination test has been used for bovine brucellosis diagnosis in Korea since middle 1950s. The reported high specificity was its value in eradication program. However, the reading of reaction mostly depends on personal experience, thus here we report a way to improve accuracy and uniformity of reading. The tube agglutination was conducted according to the protocol provided by Korean Ministry of Agriculture and Forestry. The intensity of reaction was measured by spectrophotometer. The relationship between turbidity and percentage clearing was generally in direct proportion and linear. The correspondent percent transmittance at 75, 50, and 25% clearing were 91, 82, and 73, respectively. Then, the degree of percentage of clearing at given international unit was measured. With about 1.5 unit of serum, the maximum percentage clearing was observed. The international unit showing 25, 50, and 75 percentage clearing were 0.61, 0.83 and 1.35, respectively. Based on the information obtained using international standard serum, the calculation of international unit of test serum was available. According to the protocol for bovine brucellosis diagnosis which provided by Korean Ministry of Agriculture and Forestry, the available range of detectable international unit was between 15 and 538. And the corresponding international units for suspicious case ranged between 42 and 127. Of the 35 sera from B abortus infected cattle, about half of them had more than 538 international units. Collectively, the reading of turbidity using spectrophotometer and application to international unit improved accuracy and uniformity of reading.
The present study was conducted to investigate the relationships of muscle fiber characteristics to dietary energy density [3.0(Low-E) vs. 3.2 (Med-E) Mcal DE/kg)] and slaughter weight [SW; 110, 125, and 138 kg] in finishing pigs (gilt vs. barrow) using a $2{\times}3{\times}2$ factorial treatment design. Forty-one longissimus dorsi muscle (LM) samples were analyzed histochemically, with growth performance and physicochemical data for the 41 animals and their LM out of 192 animals and 72 LM used in a previous study retrospectively included. The ADG was less (P<0.01) in the Low-E than in the Med-E group (0.93 vs. 0.73 kg) whereas lightness ($L^*$) and redness ($a^*$) of LM were greater in the Low-E group SW did not influence these variables. The diameter and perimeter of the type I (slow-oxidative), type IIA (fast oxido-glycolytic) and type IIB (fast glycolytic) fibers increased with increasing SW whereas densities of the fibers decreased. However, the number and area percentages of the fiber types were not influenced by SW or dietary energy density. The percentage and per-$mm^2$ density of type IIB fibers were negatively correlated with SW (r = -0.33 and -0.57, with P<0.05 and <0.01, respectively), whereas type I fiber number percentage was positively correlated with SW (r = 0.31; P<0.05). Marbling score was negatively correlated (P<0.05) with type I (r = -0.36) and type IIB (r = -0.39) fiber densities. The $a^*$ was correlated (P<0.01) with both type I and type IIB fiber number percentages in the opposite way (r = 0.42 and -0.47, respectively). However, $L^*$ (lightness), drip loss and $pH_{24h}$ were not correlated with the fiber number percentage or density of any fiber type. Collectively, results indicate that muscle fibers grow by hypertrophy during the late finishing period, but that fiber characteristics other than the size are not significantly influenced by dietary energy density or SW.
Since stress can cause a variety of diseases, the relaxation of stress is an important factor for preventing diseases. One way to relieve stress is to use auditory or visual materials. If auditory and visual ones are used together, the effect of stress relaxation will be maximized. In this context, we analyze mood distribution of genre of music and color distribution of mood from the mood data for musics and color data for mood words collected directly from volunteers. Based on these two distributions, we also perform the $X^2$-test with Minitab for checking that color distributions are different from genre to genre. The results show that a different genre has a different color distribution and that the distributions of color, brightness and saturation depend on mood (P<0.0001). The results will be used to develop an emotional lighting system which plays lighting according to music mood, which can be applied to psychotherapy but more data and analysis are needed for clinical trials.
This study deals with the visual quality in the future urban landscape and architectural environment, and as such, aims to identify a scientific and objective aesthetic and visual quality from the perspective of empirical aesthetics. The empirical aesthetics provides a framework that can be utilized in understanding human perception, consciousness, and behavior and a way to categorize the visual quality and to explain and predict its effect. The study examines various theories on environmental perception, cognition, and some new approaches to environmental aesthetics, and tries to present aesthetic properties that can be applied to environmental design. First, the aesthetic experience in visual perception can be defined as a combined effect of psychobiological properties and human activity, i.e. an interaction between the formal and symbolic signs in environment and the conceptual framework of man. The effect of visual quality differs and varies a great deal, depending on the sociocultural, personal and collective value system, so it is hard to define it in absolute terms. Second, the impact of visual quality and its aesthetic effect has to do with pleasure, preference, the aptitude for survival, and self regulation. Third, aesthetics is one of the areas that can benefit a great deal from an interdisciplinary approach. and an empirical study such as this can be used as a basis for design, planning, and evaluation.

Large portion of the domestic bridges are slab bridges reflecting the geographical characteristic of the country, where exists lots of inclines and small winding brooks. Many of the slab bridges are damaged and superannuated as they become obsolete. Deterioration is accelerated when the traffic density becomes large and heavy vehicles pass frequently. A strengthening method for deteriorated slab bridges was studied in this work. The examined net-type strengthening method uses both longitudinal and transverse prestressing for strengthening. In this way, the deflection at the center of the slab can be better controlled, and consequently, the slab is more efficiently strengthened. Three slab specimens were fabricated for the experimental test and subjected to three different loading conditions, and the load bearing capacities and deflections of slabs were examined. Flexural stiffness of slabs increased by 30.7~107.3%, and deflection of slabs decreased by 27.6~52.2% after net-type strengthening. The net-type prestressing is efficient to the strengthening for the center of a slab, and its efficiency is also valid under eccentric loadings. Since extra prestress forces can be added in the future, if necessary, the net-type strengthening system is advantagous for the maintenance and repair of slab bridges.
Social media environment has had a significant effect on 'power shift' over the world. Such change was due to the choice of smart people. Accordingly, the Smart Citizens Party PR strategies of $S^6M^2AR^3T^4$ should be formulated in accordance with times. Now, politicians or parties can gain a Specific, Simplicity, Sharing and Strong Synergy effect through Social Network Service (SNS). In addition, in order to embody Mighty, Measurable, and Achievable policies, policy-makers should formulate policies based on a Realistic basis, which can gain people's Reliability in every field Relevant to people's way of a happy life by giving them Time of equal opportunity and making them share the same vision and Target with Target segmentation for all sorts of people, Together. In this sense, twelve kinds of alternative words in The Smart Citizens Party PH strategies are suggested. The study suggests desirable direction of development and alternatives in regard to the trends of The Smart Citizens Party PR strategies. Alternatives that are given in this research paper will receive the people's choice because they are a dynamic force to execute 'mighty and powerful Korea'.
The trend of the concept for modern medicine is gradually forwarding to preventive medicine from therapeutic medical science. One of the most remarkable characteristics of oriental medicine is that it attaches greater importance to preventive medicine scientifically. The basic theory of oriental medicine principally takes roots in Huang Di Nei Jing and it is Si Qi Tian Shen Da Lun that is deep-rooted in the principle of "growing life" grounded in theory of unity of heaven and man of oriental medicine. Therefore having translated annotation of 〈Si Qi Tian Shen Da Lun·Huang Di Nei Jing Su Wen〉 which is quoted frequently and using it for appendix and comparing each views of annotators, I would like to state the results of dissertation as below. 1. Si Qi Tian Shen of title of the paper means that it keeps our health and prevent diseases in advance to control our mind and rhythm of life to the change of Yin and Yang - that is, the grower Yin, the looser Yang - following four seasons of nature environment. 2. The summary of this dissertation is that spring means things newly sprout from old ones, things become profuse, beautiful and brilliant in the summer. Autumn stands for things is harvested and allocated evenly and finally things is closed and stored. That is, in the spring and summer. If one break this principle of growth, diseases are followed after this. Therefore an excellent physician should handle diseases before they are attacked not remedy them after outbreak of diseases. It is said that a sage governs the nation before it is put into confusion. 3. These four terms standing for each season describe definitely and realistically rural life in the agricultural environment, in other words, spouting in spring, growing in summer, harvesting in autumn, storing in winter. Going with the current of the times, they have developed to theoretical concept of getting, growth, harvest, store so that implied the principle of growth for four seasons. 4. It means in a concrete way "Yang would grow in the spring and summer and Yin would grow in autumn and winter" as follow. That is, when the day is long, things act energetically and emit the warmth of life and expand the vigor of growth. On the other hand, when the night is long, things lessen their activity to protect the warmth of life and to preserve the sprit of growth. In addition, we should be concerned about the work outward and try to concretely fulfill plan of business in spring and summer. It is in autumn and winter when we should grow Yin. It does not mean that we simply grow cold yin in our body to build Yin. But according to annotators, for example, Wang Bing stated that we need to make things be cool in spring and summer, and be warm in autumn and winter for improvement. Zhang Jie Bin noted that things should not be cold in spring and summer and not be too hot to improve in autumn and winter. Those principles theorized to unify physiological status into the principle of changing of Yang and Yin in the nature and enriched the contents. In these principles, no problems are not found logically somewhat.
The Seokgatap pagoda composed of mainly alkali granite and other minor pink-feldspar granite, fine-grained granite, granodiorite, diorite, gabbro, and tuff. Despite the small loss and damage derived from joints, its peel-off and exfoliation are serious enough to cause the heavy deterioration on the stone surface. The chemical and petrological weathering has partly replaced the original rock-forming minerals with clay minerals and iron oxyhydroxides. Based on the petrogenesis, rock materials of the pagoda is very similar to rocks of Dabotap pagoda and the Namsan granite in the Gyeongju. The central fart of the pagoda has sunken highly, which caused all the corners to split and the structural transformation to become worse. The reverse V-shaped gaps between the materials have broken stones filled in a coarse way. The iron plates inserted between the upper flat stone laid on other stones and tile pagoda body in the north and east side has been exposed in the air and corroded, discoloring of the adjacent stones. The overall diagnosis of the Seokgatap pagoda is the deteriorated functions of the stone materials, which calls for a long-term monitoring and plans to reinforce the stone surfaces. But the main body including the pagoda roof stone needs washing on a regular basis, and the many different cracks should be fixed with glue by using the fillers or hardeners designed for stone cultural properties after removing the cement mortar. In case of the replacement of the stone materials with new stones, it's necessary to examine the pagoda for the center of gravity and support intensity of the materials. The structural stability of the pagoda can be attained by taking a reinforce measure in geotechnical engineering and making a drainage. The ground humidity, which has aggravated weathering and structural instability, should be resolved by setting up a humidity reduction facility. The contamination of lichens and bryophyte around the pagoda and on the surface is serious. Thus biochemical treatments should be given too in order to prevent further biological damages and remove the vegetation growing on the discontinuous planes.

Many surface protection methods have been developed to apply to constructional steels which have been used under severe corrosive environments. One of these methods, hot dip galvanizing is being widely used to the numerous constructional steels such as a guard rail of high way, various types of structural steel for manufacturing ship and for some other industrial fields etc.. Recently, the cost of zinc is getting higher and higher, thus, it is considered that improvement of hot dip galvanizing process to reduce the cost of production should be developed possibly. In this study, additives such as acid cleaning solution, $NH_4OH$, $Al(OH)_3$ and $H_2O_2$ were added to flux solution, and omission of water washing treatment after acid cleaning was investigated with some types of flux solutions added with some additives mentioned above. The decrement of pH by adding the acid cleaning solution could be controlled due to neutralization reaction with addition of $NH_4OH$. The flux solution added with both $NH_4OH$ and $Al(OH)_3$ exhibited nearly the same color and pH value as those of orignal flux solution with no added, and the sample dipped to the flux solution which was added with additives mentioned above indicated a relatively good corrosion resistance compared to other samples. However, the flux solution added with $NH_4OH$, $Al(OH)_3$ and $H_2O_2$ exhibited a different color, sediment and a bad corrosion resistance. Consequently, it is considered that omission of water washing treatment may be able to perform by adding optimum additives to the original flux solution.
