Objectives: The aim of this study was to investigate 1) the prevalence of depressive symptoms, 2) the severity of depressive symptoms, 3) the correlation of depressive symptoms with clinical variables, and 4) factors that contribute to depressive symptoms in patients with Parkinson's disease. Methods: One hundred eighteen patients with Parkinson's disease referred from the Parkinson's Disease Clinic of Dong-A University Hospital, Busan, Korea, completed a self-administered questionnaire package, which included basic demographic data, the Beck Depression Inventory, the Parkinson's disease quality of life questionnaire, the Symptom Checklist-90-Revision(SCL-90-R), and the Spielberger's State-Trait Anxiety Inventory. In addition, a structured interview and a complete neurological examination, including the Hoehn and Yahr stage, the motor part of the Unified Parkinson's Disease Rating Scale(some selected scales of UPDRS part III), the Schwab and England Activities of Daily Living scale(ADL), and the Korean version of Mini-Mental State Examination were performed. Results: 1) Based on BDI score, subjects were divided into four groups:severely(40.7%), moderately(13.6%) and mildly(12.7%) depressive and non-depressive(33.1%). 2) The severity of depressive symptom in Parkinson's disease was positively correlated with Hoehn and Yahr(H & Y) stage(r=0.34, p<0.0001), the severity of motor symptom(r=0.35, p<0.0001), and trait anxiety inventory(r=0.33, p<0.001). On the other hand, the severity of depressive symptom was negatively correlated with educational level(r=-0.34, p<0.001), ADL(r=-0.37, p<0.0001) and Parkinson's disease quality of life (PDQL)(r=-0.69, p<0.0001). Among several clinical variables, the PDQL was the most influential factor predicting whether the depressive symptom was present or not. Conclusion: This study suggests that depressive symptom is very prevalent among patients with Parkinson's disease. Data from this study indicate that medical staffs who take care of patients with Parkinson's disease should pay attention to finding and treating depressive symptom among their patients. With appropriate psychiatric intervention, patient's depressive symptom can be minimized or alleviated and thus, the quality of life in these patients is likely enhanced.

Researches on integration of design and construction information from earlier era focused on the conceptual data models. Development and prevalent use of commercial database management system led many researchers to design database schemas for enlightening of relationship between non-graphic data items. Although these researches became the foundation fur the proceeding researches. they did not utilize the graphic data providable from CAD system which is already widely used. 4D CAD concept suggests a way of integrating graphic data with schedule data. Although this integration provided a new possibility for integration, there exists a limitation in data dependency on a specific application. This research suggests a new approach on integration for design and construction information, 'Product Model Centered Integration Methodology'. This methodology achieves integration by preliminary research on existing methodology using 4D CAD concept. and by development and application of new integration methodology, 'Product Model Centered Integration Methodology'. 'Design Component' can be converted into digital format by object based CAD system. 'Unified Object-based Graphic Modeling' shows how to model graphic product model using CAD system. Possibility of reusing design information in latter stage depends on the ways of creating CAD model, so modeling guidelines and specifications are suggested. Then prototype system for integration management, and exchange are presented, using 'Product Frameworker', and 'Product Database' which also supports multiple-viewpoints. 'Product Data Model' is designed, and main data workflows are represented using 'Activity Diagram', one of UML diagrams. These can be used for writing programming codes and developing prototype in order to automatically create activity items in actual schedule management system. Through validation processes, 'Product Model Centered Integration Methodology' is suggested as the new approach for integration of design and construction information.

It is not easy to define the priority criteria of the need of conservation treatment for stone cultural heritage, although many of them have been treated and restored over the past decade. This study approached the correlation between damage grade and the need of conservation treatment based on damage diagnosis of stone cultural heritage carried out from 2001 to 2005. The number of Third-graded (from First to Fifth-grade) stone heritage in deterioration was the highest among state-designated stone cultural heritage. The Fourth-graded stone cultural heritage (143 in total) was mostly influenced by high physiochemical deterioration, whereas the Fifth-graded ones (61 in total) was dominantly affected by biological colonization. It was estimated that total 211 stone cultural heritage were treated for conservation and restoration from 2002 to 2011. They were usually cleaned (total 134, 26.1%), joined and consolidated, and maintenance works as shelter construction, drainage installation and surrounding cleaning were carried out for some of them. The number of conservation intervention increased with the high deterioration grade, and the case number of metamorphic and sedimentary rocks. By age, the stone cultural heritage in Three-kingdom Period were treated the most, and other heritage in Unified Shilla, Goryeo and Joseon showed an approximate ratio. The stone cultural heritage fallen in the fifth-grade in deterioration demonstrated the highest ratio, approximately 80% of conservation intervention. These results can be used as preliminary data to define the emergency criteria for conservation intervention policy.

This study was carried out to find contradiction factors on laws for children's activity spaces and facilities and to suggest the rational options to control and manage those spaces and facilities by environmental and landscape planning methods. The results of this study are as follows: 1. The major laws related to the environmental safety for children's activity spaces are "Environmental Health Act (ERA)" for managing the environmental safety of children's activity spaces; "Safety Supervision Law of Children's Play Facilities(SSLCPF)" for the inspection and management for safety of children's play facilities; "Quality Management and Industrial Products Safety Management Law(QMIPSML)" for managing safety certification on children's play equipments. 2. The interior space such as "living room" by the Children's Welfare Law(CWL), "Children Park" by the Act on Urban Parks and Green Spaces(AUPGS), "classroom" on private educational institutes by the Act on Establishment and Operation Private Lesson and Training(AEOPLT) and "nursing room" of child care center smaller than $430m^2$ are needed to be managed as an activity space. 3. In order to reduce industrial burden in the production, establishment, construction, and operation and to minimize unwilling extra burden in the administration effort due to legally double regulate, it is necessary to mitigate the inspections on the equipment certificate from QMIPSML and overlapped or different factors and standards must be unified. With this study, the landscape domain could he enlarged from producing, import of play equipment and establishment, construction and operation of play facilities for a comprehensive range of activity spaces, and the landscape industry such as engineering industry, academic research, management, etc.

Due to the introduction of CR and DR, it has been neglected the use of the X-ray beam collimator and field size. This study examines nationwide survey of the proper use of collimator and field size by area in a specific field of plain radiography and the current status. Authors emphasized the need for the field size criteria, and propose a standard reference field size in each specific radiologic examination. Total 333 medical institutions (included in Seoul, Gyeonggi-do, Jeolla, Chungcheong, Gangwon-do, Busan area), were investigated in relation to the status of the X-ray beam collimation field size, type specific inspection areas, medical facilities, and image analyses by type to figure out whether they use the adjustment of image field to the specific examination. To assess the awareness and the impact of radiation exposure to the collimation adjustable, 168 radiographers who was working in 10 general hospitals, 10 hospitals, and 10 clinics, were surveyed how they haver adjusted the actual field size. We examine that 61.3% of medical institutions used the "Proper collimation" and only 49.9% of them employed proper one in lumbar spine densely crowded by major organs. 69% among general hospitals, and 65% among hospitals using DR system were using proper collimation. Radiographers recognized that proper adjustment of collimation could reduce the harmful radiation dose on patients. In the survey, 97.6% of respondents were aware of this fact, but only 83.3% of respondents did the adjustment of the size of the collimation field. The using of proper collimation field was low in the nationwide survey, so the effort to reduce the radiation dose on the patients is urgently needed. A unified standard for the field accompanied by thorough education should be needed.

Purpose : To evaluate the diagnostic significance of simultaneous examination of hematuria and proteinuria in the urinary mass screening for early detection ot incipient renal diseases. Method and Object : During the period of 4 months from August to December in 1997, we did urinary mass screening on students of first grade of high school (16 years aged group) nationwide together with Korean Association of Health(KAH). In the first screening test, Comber-10 $N^{(R)}$ M dipsticks were used to detect proteinuria, hematuria, pyuria and nitrite simultaneously. Total 26,508 students (16 years aged group) from 33 high schools in every province in Korea, respectively, complied to the urinary mass screening. After then, one high school in Seoul was selected to reveal the true incidence of incipient renal diseases among students who showed hematuria in the initial screening through intensive examinations. Those who had hematuria and/or proteinuria visited the Paik hospital, and underwent blood tests and ultrasonographic examinations. The results were evaluated. Results 1) The initial screening revealed that the prevalence of proteinuria, hematuria, pyuria and positive nitrite urine, were $0.73\%,\;2.69\%,\;0.23\%\;and\;0.03\%$, respectively. 2) The first urinary screening among 875 students from one high school in Seoul selected fir the second test showed proteinuria, hematuria, pyuria and positive nitrite urine, were $0.91\%,\;4.68\%,\;0.34\%\;and\;0\%$, respectively. a) Total 8 among 875 students showed proteinuria, but one of them had orthostatic proteinuria and those remaining 7 students had transient proteinuria. b) There were 41 students who had hematuria in the initial screening. Among 33 who complied the second test, only one student showed asymptomatic isolated hematuria and those remaining students were normal. Conclusion : 1) Because of high false positive hematuria rate in the urinary mass screening, it dosen't seem to be appropriate that hematuria screening using dipsticks be included in the urinary mass screening. 2) A unified organization is needed from the fret that so various results of urinary mass screening came out. 3) Positive rates of pyuria and nitrite were so low that validity of urinary mass screening for urinary tract infection needs more studies.

The functions and roles in the various fields of modern society are changing into the unified and multiplex structure, which is simultaneous and virtual communication environments beyond physical space and time, by the digital IT technology. The urban traffic system is also being intellectualized in order to solve urban traffic problems and convenient services by using digital IT technology. The bus, which is the one of the most common public transportation, are suffering in the decrease of bus service quality and the bus passengers rate because of the development of other public transportation systems such as the subway and electric railway and by rapidly increasing private cars. By recognizing these problems, many domestic and overseas cities are promoting to introduce the Bus Information System (BIS) to improve service quality of buses through the intelligent traffic system. According to the construction of this new information system called the Bus Information System (BIS), the new bus stop configuration system and design plans are being required to solve the existing bus stop information system. Therefore, this research was conducted to suggest an effective BIS configuration system plan and synthetic design goals based on the investigation the problems of the information system and the BIS configuration system for Busan city. Also, this research are conducted the below actions as follows: First, the literature survey was conducted, such as theoretical documents on the bus stop and the Bus Information System(BIS), Also, the design trend of the BIS was examined through domestic and overseas BIS cases studies. Scondly, the problems related to the information system in Busan city bus stops were investigated to investigate the present state and problems of the Bus Information System (BIS). Finally, as a result of this research, the effective BIS configuration system plan and design approach methods of bus stops were proposed for by Busan city based on the above investigation results.

This research explored the relationship between the water quality issue of Wolji Pond (Anapji Pond) with the maintenance of the channel flow circulation system. The water supply and drainage system closely related to the circulation system of pond has been reviewed, rather than the existing water supply and drainage system that has been analyzed in previous studies. As a result of reviewing the water supply system, it has been learned that the water supply system on the southeastern shore of Wolji Pond, being the current water supply hole, has been connected to the east side garden facility (landscaping stone, curved waterway, storage facility of water) between the north and south fence and the waterway. This separate facility group seems to have been a subject of the investigation of the eastern side of Wolji Pond, with the landscaping stones having been identified in the 1920's survey drawings. The water supply facility on the southeastern shore, being the suspected water supply hole, seems to have some connection with the granite waterway remaining on the building site of Imhaejeon (臨海殿) on the southern side of Wolji Pond. It is inferred that it provides clean water, seeing that the slope towards the southwestern shore of Wolji Pond becomes lower, the landscaping stones have been placed in the filter area, and it is present in the 1920's survey drawings and the water supply hole survey drawing of 1975. The water drainage facility on the northern shore is composed of five stages. The functions of the wooden waterway and the rectangular stone water catchment facility seem not to be only for the water drainage of Wolji Pond. In light of the points that there are wood plugs in the wooden waterway and that there is a water catchment facility in the final stage, it is judged that the water of Balcheon Stream (撥川) may be charged in reverse according to this setup. Namely, the water could enter and exit in either direction in the water drainage facility on the northern shore It also seems that the supply to the wooden waterway could be opened and shut through the water catchment facility of rectangular stone group as well. The water drainage facility on the western shore is very similar to the water drainage facility on the northern shore, so it is difficult to avoid the belief that it existed during the Silla Dynasty, or it has been produced by imitating the water drainage facility on the northern shore at some future point in time. It seems to have functioned as the water drainage facility for the supply of agricultural water during the Joseon Dynasty. The water supply and drainage facilities in Wolji Pond have been understood as a systematized distribution network that has been intertwined organically with the facility of Donggung Palace, which was the center of the Silla capital. Water has been supplied to each facility group, including Wolji Pond, through this structure; it includes the drainage system connecting to the Namcheon River (南川) through the Balcheon Stream, which was an important canal of the capital center.

China is experiencing rapid economic development and the volume of air passengers and cargo transportation has increased significantly in recent years. To the contray, the regulations on liability of air carrier in china fall behind and are not sufficiently applicable in disputes. Their lack of sufficient protection for air passenger's interests became obstructive factor for further developments of Chinese air transportation industry. The legal system of air carrier's liability mainly consists of the contents as followed. The liability period, the scope of liability, amount of compensation for damage, limitation of liability, liability exemption of air carrier, jurisdiction, limitation of action, applicable law etc. Laws and rules concerning these issues are regulated in Civil Aviation Law and regulations published by Civil Aviation Administration of China. This article described the main contents of air carrier's liability and examined the legislative problems in their applications in real cases. In order to solve the legal problems on the air carrier's liability and disputes between wrongdoers and survivors etc, it is necessary and desirable for china to amend revelvant provisions. One of my proposals is to raise the amount of compensation limitation for damage. And I also would like to suggest that Civil Aviation Law should treat international and domestic transportation equally on the limitation of compensation for air carrier's liability. China has also acceded to the Montreal Convention of 1999 on July 31, 2005. This is an effort to make the law of air carriage unified worldwide through various international conventions to achieve conformity between rules of international air carriage and that of Chinese domestic aircarriage. Furthermore, there should be additional detailed implementation rules for air carrier to assume liability for the losses to passengers, baggage or cargoes caused by delays in the air transport. Significant clarifications are also needed for provisions concerning whether and how air carrier assume liability for moral damage caused by accident.

The mural portraits of the ancient Dukheungri tombs are very important for the study of our traditional costume because the tomb contains a stone. with the in-scription of the date of its erection, 408 A.D. and the name, and official status of the buried. The costumes shown in the mural paintings will be the basis on which historical research can be made concerning costumes before and after 400 A. D. The costume in the mural paintings is classified into five different categories; You (jacket), Po (overcoat), Go (trousers), Sang (skirt), and Gwan (hat). Comparing these categories with those of other mural paintings lead us to the following conclusions. 1. The length of the You (jacket) reaches below the buttocks and the sleeves are narrow. The edges of the sleeves are decorated with stripes. The You (jacket) over-laps on the right, center, and left sides, and there are many Jikryong (V-collar) and Danryong (rounded collar) styles, but it has a similar tendency to others of the Pyongyang area which exhibit many foreign influences. In a departure from tradition. the belts on the men's You (jackets) have only 3 knots in the front, with the back having more knots than the front. The belts of the women's You (jacket) seem to have had a band or button for fastening. We must re-evaluate the assumption that the You (jacket) and Go (trousers) of the northern peoples had the common characters of a belted You (jacket) and Po (over-coat) and that the Gorum originated from the Goryo or Unified Silla dynasty. The outside of the sleeves are longer and more to the side than the inner garment (underwear) so that the sleeves of the inner garment frequently overlapped the outer dress. The above mentioned facts have lead to the discovery of the "Hansam," "Tosi" and "Geodoolgi." 2. The Po (overcoat) was used only by the upperclasses and differs from those found in other mural tombs. The Po (overcoat) of the noble on the tomb mural is centered with an overlapping Jikryong (V-collar) while the other Po (overcoats) of the upperclasses are characterized by an overlap on the left, a Danryong (rounded collar) with two types of sleeves (wide and narrow). Foreign influences and traditional influences coexist in Po (overcoat). Belts have frontal knots without exceptions. The facts that the belts on the You (jackets) are on the front and the belts on the Po (overcoats) are on the back must be reexamined. 3. Go (trousers) is usually narrow, being wider in the rear and narrower below the knees. They were used by hunters on the back of horses with similar Go (trousers) from the Noinwoowha tombs being typical of the northern peoples. 4. Sang (skirts) are pleated as commonly seen in the Goguryo murals. The size of the pleat is varied, each pleat being characteristically wider and having different colors. Same types of pleat are discovered in Central Asia and China. It is uncertain whether the pleat of Goguryo was originated in Central Asia and China or only interrelated with those of the areas. 5. There are three kinds of Gwan (hats); Nagwan, Chuck, and Heukgun. Nag-wan was worn by the dead lords and their close relations. Chuck has three cone shaped horns. Heukgun was worn by military bandmen and horsemen. There are two kinds of hair styles. The up-style was used by the upperclass people closely related to lords, and other people used the Pungimoung hair style. The hair styles of the men and women are characterized by the Pungimoung style. which is a Chinese influence, but still retain their originality. The costume has a similar tendency from those from Yaksuri mural tombs, Anak No. 2 and Anak No. 3. We need to reexamine the costumes from $4{\sim}5$ century murals according to the Dukheungri murals. The costumes of Goguryo share many common factors with those of Western Asia, Central Asia and Ancient China (Han). It seems due to the cultural exchanges among the Northern peoples, the Western and Central Asians, and the Ancient Chinese. It may have resulted from the structural identity or morphological identity of the peoples, or their common social and natural environments and life styles. It will be very valuable to study the costumes of Japan, China, and Korea to find out the common factors. It is only regretful that the study is not based on direct observations but reported information made by 77 persons, because Dukheungri is an off-limits area to us.
