This study was conducted to provide information which will be useful for establishing and implementing effective management policy for Baekdudaegan Trail and user satisfaction by investigating the characteristics of trail use and users' perceptions of the environmental impacts on the trail. For this purpose, a questionnaire survey was employed in Baekdudaegan trail by three topological types. With this classification, the characteristics of the way the trails used and users' perceptions of the impacts were analysed in terms of ecological, physical and social environments. The result showed that the Baekdudaegan trail was used mainly for mountaineering rather vacation or travel, and found no differences in the characteristics of the trail use by the types. Ecological environment showed no significant relation with user satisfaction, however changes in physical environmental factors such as a trail width functioned as a negative component to decrease use experience. In addition, the satisfaction of the users had little to do with social environment, when the level of using the trail was relatively low. To present, the levels of impacts on ecological, physical and social environments and the users' satisfaction level regarding the Baekdudaegan trail appear to be positive. However, the increase of use level is expected in the future, and therefore systematic managerial measures need to be implemented to monitor the changes of the trails and interactions of the environmental impacts.

Myeong(明) Dynasty Period put together clinically various medical theory in Song(宋) Dynasty and Geum-Won(金元) age, organized medical system. They have been developed in theory, which thought of Byeonjeungronchi(辨證論治) more important, and clinical part which included diagnosis, therapy, prevention. In that age reactional medical thought was in fashion because of affect of Ihak(理學), therefore pediatrics have been affected from them. Especially, looking at the symptom of Byeonjeungronchi doctors, Manjeon(萬全), Nobaeksa(魯伯嗣), Wangdaeryun(王大綸), Wanggeungdang(王肯堂), Nuyeong(樓英) had succeed to Jeoneul(錢乙)' the five viscera Byeonjeung(辨證) system. Manjeon advocated Samyuyeosabujokron(三有餘四不足論) about Jangbu(臟腑) and organized the curative principle about Ojangheosil(五臟虛實). Gupyeong(寇平), commented on diagnosis of five viscera and classification of disease of five viscera. Wangdaeryun in the close of Myeong Dynasty Age explained main pulse, pulse of illness in detail according to weakness or strength of five viscera, pathological or physiological features of five viscera and Saenggeuk(生克) relation of Ohaeng(五行) in the book of "Yeongdongryuchwe(嬰童類萃)". Wanggeungdang and Nuyeong had organized system of argument which classified disease as a result of symptom of five viscera. "Yugwajeungchijunseung(幼科證治準繩)" and "Uihakgangmok(醫學綱目) Soabu(小兒部)" had been written by this principle. Nobaeksa had arranged the principle of cure about five viscera and explained method of common use about each organ's disease. Besides, Seolgi(薛己), Janggyeong-ak(張景岳), insisted about Myeongmun(命門) because he thought of Bisin(脾腎) of children and vigor by nature importance. Seolgi had applied and used very well Bojung-ikgitang(補中益氣湯) based on Idongwon(李東垣)'s Biwiseol(脾胃說) and controled and helped spleen and stomach. At the same time, he took a serious view about supplementing children's Sin-gi(腎氣) according to so many spleen and stomach disease was fallen because they couldn't make warm the spirit of Jungju(中州), result of weakening Hwa(火) of Myeongmun. Also Janggyeong-ak took a serious view strengthen of Bisin, so he assorted and used Insam(人蔘) and Buja(附子) to supplement children's weaken energy in kidney Jeonggi(精氣).

Objectives : This study aimed to clarify the difference in blood homocysteine levels of acute cerebral infarction patients categorized by Sasang constitutional medicine. Methods : The subjects were recruited from patients admitted to the Oriental Internal Medical Department at Kyunghee Medical Center between October 2005 and May 2007, who were classified as small vessel occlusion (SVO) patients according to the Trial of ORG 10172 in Acute Stroke Treatment (TOAST). The general characteristics along with total homocysteine levels were recorded and analyzed according to Sasang constitutional medicine. Results : A total of 151 patients were included in the trial. The prevalence of constitution was, in order, Soyangin, Taeumin, and Soeumin. No statistical significance was noted for any characteristic except body weight. There was no significant difference in blood homocysteine levels between constitutions. Conclusion : This study investigated the difference in blood homocysteine levels of acute cerebral infarction patients categorized according to Sasang constitutional medicine. Due to many limitations, the correlation between homocysteine levels and Sasang constitution was not clarified. Nevertheless, this study is significant in that it examined the largest study group to date in Oriental Medicine research history on the relation between stroke patients' homocysteine and Sasang constitution, and can be utilized in future as a basic material. Further research on the subject is needed.

As for the public, it is hard to understand semiotics because of the scope of an enormous semiotics education. This study is making semiotics of Charles Sanders Peirce the subject. I thought that utilization can hold his semiotics study in a visual design field. First of all, this study considered design related papers related to the existing semiotics again and study found an error of the existing semiotics study and understanding did category concept with re-definition about semiotics of Peirce. Explained a symbol mark through understanding of semiotics of Peirce. This study was able to get the following conclusion through these results. 1) A symbol mark means one product, sonics, company oneself with a custom. Therefore, it is a rule symbol in the Representation side. 2) A symbol mark symbolizes an object with one symbol, so a symbol mark is a symbol in an object. 3) Because a symbol mark exists through a social rule, in semiotics definition of Peirce, this must become understanding with a Argument symbol. 4) A symbol mark is what a company or an organization field used from the past, and the public are recognizing this how. Therefore, it works as fact a company attaches a symbol mark to own product, and to show the public a symbol mark. A symbol mark is Dicent Sign in Interpretant. A rule and understanding about a lot of types which have various mutual relation, Peirce classification and understanding of a symbol mark tells to demand is holding that understanding a type of semiotics with the concept that is not an image to us.

Recently, Korea's defense industry has advanced highly, and defense R&D budget is gradually increasing in defense budget. However, without objective analysis of defense industry technology, effective defense R&D activities are limited and defense budgets can be used inefficiently. Therefore, in addition to analyzing the defense industry technology quantitatively reflecting the opinions of the experts, this paper aims to analyze the defense industry technology objectively by quantitative methods, and to make efficient use of the defense budget. In addition, we propose a patent analysis method to grasp the characteristics of the defense industry technology and the vacant technology objectively and systematically by applying the big data analysis method, which is one of the keywords of the 4th industrial revolution, to the defense industry technology. The proposed method is applied to the technology of the firepower industry among several defense industrial technologies and the case analysis is conducted. In the process, the patents of 10 domestic companies related to firepower were collected through the Kipris in the defense industry companies' classification of the Korea Defense Industry Association(KDIA), and the data matrix was preprocessed to utilize IPC codes among them. And then, we Implemented association rule mining which can grasp the relation between each item in data mining technique using R program. The results of this study are suggested through interpretation of support, confidence lift index which were resulted from suggested approach. Therefore, this paper suggests that it can help the efficient use of massive national defense budget and enhance the competitiveness of defense industry technology.

In the construction of high-rise residential buildings in which the finishing works are done repetitively in each housing unit, the construction period and cost can be reduced, while maintaining the quality, if the work process is properly managed in order for the resources to be input continuously. Time management methods such as the Bar Chart, CPM and LOB are not appropriate, due to the difficulties involved in the diagraming of repetitive works and applying them to the project. The Tact method also has difficulties in maintaining a constant work flow and needs significant effort and cooperation from the subcontractors to allocate the resources consistently. Partitioning, base works for finishing, floor mortar plastering and the final finishing work are done sequentially in residential buildings projects, and there are many repetitive activities which differ in terms of the work method, work area and productivity. If these repetitive activities are synchronized or converged toward the last work area, the goal of process management can be achieved effectively. Therefore, a process planning method for the finishing works of residential building projects is proposed, which takes into consideration elements, such as the sequential relation between the activities in each housing unit and classification of repetitive works in terms of their management method, work area and production rate, for the continuous input of resources into the housing units.

The purpose of this study is to analyze the various processes and patterns to build or synthesize class numbers in the 800 class of the Dewey Decimal Classification, Edition 20(1989). The results of the analysis are as follows: 1. The 800(Literature and rhetoric) class in the DDC system is the main class added analytico-synthetic principle positively to an enumerative scheme. 2. The facets to be a n.0, pplied in literature are language literary form literary period ; kind, scope, or medium ; notation 08(collection) or 09(criticism) literary feature, subject, author, etc. 3. In the 800 class, there are the five tables of precedence for literary forms aspects ; specific kinds of persons ; literary, period in relation to the aspects for works treating more than one literary form subforms, aspects and literary periods in the works treating a specific literary form. 4. The basic number synthesis of literary works proceeds through the various facets in the following sequence, as far as necessary for the item : base no. + literary form + literary time or period + kind, scope, or medium + notation 08 or 09 + subform + additional notation from T3C and other tables. 5. In view of the multiplicity of facets, their synthesis formulas take the following order : (1) Works about the literature : base no.(schedule) + language(T6) or form(T3B) (2) Works by or about individual author : base no.(schedule) + form (T3A) + period(schedule) + subform(T3A) (3) Works by or about more than one author, not restricted by language facet : base no.(schedule) + period(T1) ; base no.(schedule) + kind, scope, medium(T3B), or feature(T3C), or person(T5). (4) Works by or about more than one author, restricted by language facet : base no.(schedule) + form (T3B) + period(schedule) + subform(T3B) + notation 08 or 09(T3B) ; base no.(schedule) + notation 08 or 09(T3B) + 9(T3C) + area notation(T2) : base no.(schedule) + form (T3B) + notation 008 or 009(T3B) : base no.(schedule) + form (T3B) + kind, scope, medium(T3B) + notation 08 or 09(T3B) + period(schedule). (5) Affiliated literatures for which period numbers are not us base no.(schedule) + form (T3A or T3B), or notation 08 or 09(T3B) : base no.(schedule) + kind, scope, medium(T3B), feature(T3C), or person(T5) 6. The problems in the number building of the 800 class are the complexity and difficulty of number synthesis, the intrinsic weakness of from distinction and the inconvenience of retrieval inherent in the form class. In order to solve these problems, therefore, the citation orders and methods of DDC should be improved and synthesis patterns simplified from the point of view of its applicability and its usefulness in the "literature class".

To evaluate the infra structure supporting hospital nutrition services, we conducted a survey on the unit of organization, unit of dietitians work system, number of personnel engaged on nutrition services, productivity of food service, management of dietitians works, computerization of nutrition services etc. Total ninety-six hospitals were participated in the survey, and they were varied in terms of hospital classification, location, number of beds and type of food service management. All of the large hospitals with more than 400 beds conducted nutrition services under the department of nutrition, but some of the middle and small hospitals with less than 400 beds conducted nutrition services under the other department such as administration. In most of the tertiary hospitals, the work of dietitians were separated in which food services and medical nutrition services were conducted independently by different dietitians, whereas, in most of general hospitals and all the hospital, food services and medical nutrition services were conducted by the same dietitians in all time. The numbers of dietitians and cooks per 100 beds were fewer in the large hospitals with more than 400 beds than the hospitals with less than 400 beds, and the number of cooking and meal serving assistants were the just opposit. The average productivity of food service was 44.5 meals per hour for each dietitian, 84.8 meals per hour for a cook and 7.0 meals per hour for a cooking and meal serving assistant. The productivities for dietitians and cooks tend to be higher in large hospitals than middle and small hospitals, whereas the productivities for cooking and meal serving assistants were just opposite. The large hospitals seemed to solve the problem on the lack of working personnels by hiring part-time workers and by utilization of computer system for their works. The pattern of daily work management in food service area was not much different between dietitians duties, but the pattern of daily work management in medical nutrition service area was different in a way which the analysis of patients nutrient intakes was almost not conducted by dietitians handling both food services and medical nutrition services. Therefore, this study demonstrates that there are significant differences in the infra structures conducting nutrition services among hospitals, suggesting that the strategies to improve this improve this structure in relation to the improvement of service qualities need to be investigated in the future.

The purpose of this study is to classify the Korean precipitation regions on the basis of the characteristics of extratropical cyclonic precipitation. From now on, extratropical cyclone is called cyclone in short. By using factor analysis and Ward method in cluster analysis, precipitation regions on the basis of the characteristics of cyclonic precipitation are classified The principal data used in this study are daily precipitation records obtained from 60 weather stations of the Korea Meteorological Service during the ten years($1981{\sim}1990$), and weather charts published by the Japan Meteorological Agency. The results obtained in this study are summarized as follows: (1) In the factor analysis using 43 variables which have relation to the extratropical cyclonic precipitations, They are seven factors whose eigenvalues are above 1.0. This explains 86 percent of total amount. The first factor explains the characteristics of precipitation in the middle-west area and its contribution degree has the highest 10.9 percent. (2) According to the cluster analysis method of Ward, extratropical cyclonic precipitation regions are classified seven macro regions(such as Kyungki and North Youngseo, Youngdong and Ullungdo, Hoseo and South Youngseo, Honam and Northwest Chejudo, Southeast Chejudo, North Youngnam, and South Youngnam), 22 meso regions. (3) The characteristics of precipitation regions have relations to the path of cyclone, the direction of air inflow and the strike of mountain ranges. As the conclusion, the Central China Low brings much precipitation in the southern coast and southern area of Korea as moving to the northeastward. The North China Low moves eastward and brings much precipitation in the western area of the Taeback mountain ranges. The probability of extratropical cyclonic precipitation is the lowest in the inland of Yeongnam and the eastern coastal areas which belong to the rain shadow region. Namely, The seasonal and spatial characteristics of precipitation are closely associated with the path of cyclone and the direction of air inflow according to its passage, and the strike of mountain ranges.

The pyramid graph is well known in parallel processing as a interconnection network topology based on regular square mesh and tree architectures. The enhanced pyramid graph is an alternative architecture by exchanging mesh into the corresponding torus on the base for upgrading performance than the pyramid. In this paper, we adopt a strategy of classification into two disjoint groups of edges in regular square torus as a basic sub-graph constituting of each layer in the enhanced pyramid graph. Edge set in the torus graph is considered as two disjoint sub-sets called NPC(represents candidate edge for neighbor-parent) and SPC(represents candidate edge for shared-parent) whether the parents vertices adjacent to two end vertices of the corresponding edge have a relation of neighbor or sharing in the upper layer of the enhanced pyramid graph. In addition, we also introduce a notion of shrink graph to focus only on the NPC-edges by hiding SPC-edges within the shrunk super-vertex on the resulting shrink graph. In this paper, we analyze that the lower and upper bounds on the number of NPC-edges in a Hamiltonian cycle constructed on $2^n{\times}2^n$ torus is $2^{2n-2}$ and $3{\cdot}2^{2n-2}$ respectively. By expanding this result into the enhanced pyramid graph, we also prove that the maximum number of NPC-edges containable in a Hamiltonian cycle is $4^{n-1}$-2n+1 in the n-dimensional enhanced pyramid.
