This thesis is a study on the change and the process of the development of the hygiene administration during the period of modernization of our nation which promoted by the open door policy of our country chiefly under the pressure of the foreign countries. During that period Korea had reorganized the old political system radically and introduced the western medical system. Through the close study of literature concerning the system of the hygiene administration, the laws of health and hygiene, the environmental sanitation organizations and their practical activities the author obtained the conclusions as following 1. The government passed around 40 laws of health and hygiene from the time when the bureau of hygiene was founded in 1894 to the annex of Korea to Japan. Most of the laws were believed to be established by the enforecement of Japanese government. When the epidemics were prevailing, a decree for the prevention of the epidemics was proclaimed by the Japanese president of the headquarters of national police. It is shown well that the sovereignty of Korea had been deprived. 2. After the armex of Korea to Japan, the hygiene police and the general police belonging to the bureau of national police shared the tasks of health and hygiene. This was a temporary system which had existed just during the colonial period. As for the water-supply which is the most important facility among the various environmental hygiene facilities, the rate of supply was remarkably high in Japanese rather than in Korean. 3. During the period of American military administration, it is notable that the division of hygiene in the bureau of national police was replaced by the bureau of hygiene. This period is regarded as the turning point when hygiene administration was operated by means of education along with the introuction of American system of public health. 4. Ever since the foundation of the republic government, the laws of health and hygiene which had been established during the colonial period have been put into operation without rriuch change except several regulations concerning food.

The purpose of this study is to find the light intensity which induced maximum gathering rate and to observe the variation of the gathering rate both in daytime and tat night by using Striped puffer, Fugu xanthopterus (Temminck et Schlegel). An experimental tank(360L$\times$50W$\times$55H cm) was set up in a dark room. An illumination system was attached to the end of one side of the tank to control horizontal light intensity. Eight artificial light sources were prepared by combination of three light bulbs (10W, 60W, 100W) and eight filters. During the experiment water depth was maintained 50 cm level in the tank. The tank was marked into six longitudinal sections each being 60cm long to observe the distribution of fish. The fish were acclimatized in dark condition for 50 minutes prior to the main experiment. Upon turning on the light, the number of fish in each section was counted 60 times every 30 seconds, and the gathering rate was obtained from the average number of fish in each section. The light intensity inducing maximum gathering rate was 298.56 lux (188.44-444.96 lux) at daytime and 298.56 lux (188.44-444.96 lux) at night. The variation of the gathering rate of fish in illumination time was increasing trend fluctuately and did not show any distinctive difference between day and night.

This study analyzes the animal symbolism shown in the novella by Hyoseok Lee and seeks to shed light on the consciousness of the author expressed through such symbolism. Lee used animal symbolism since 1933 which was a literary turning point for him. Animal symbolism in his novels are more than an analogical theme but is used as a core meaning and image. This has a clear intention of the author underneath. Novella which is seen as the starting point of pure literature for Lee, uses the animal pig as a key symbol. The pig serves as a symbol of the capital for poor farmers, while also serving as an amplifier for the desires of the protagonist. The death of the pig that appears at the closing of the novella stands for the tragic reality of the farmers of the time who could not seek growth in their capital or realization of their desires. As such, has characteristics of pure literature but also represents the consciousness of the author who brings attention to the tragic reality of farmers. That is, is a work that realized the unique writing style of Lee and his animal symbolism to bring to life a middle way appraoch to realism and romanticism.

The purpose of this study is to find the light intensity which induces maximum gathering rate and to observe the variation of the gathering rate both in daytime and at night by using marbled sole, Limanda yokohamae (Gunther). An experimental tank ($360L{\times}50W{\times}55H\;cm$) was set up in a dark room. An illumination system was attached to the end of one side of the tank to control horizontal light intensity. Six artificial light sources were prepared by combination of two light bulbs (5W, 150W) and seven filters. During the experiment water depth was maintained 50 cm level in the tank. The tank was marked into six longitudinal sections each being 60 cm long to observe the distribution of fish. The fish were acclimatized in dark condition for 50 minutes prior to the main experiment. Upon turning on the light, the number of fish in each section was counted 40 times every 30 seconds, and the gathering rate was obtained from the average number of fish in each section. The light intensity inducing maximum gathering rate was 1.9 lux ($1.2{\sim}2.9\;lux$) in the daytime and 0.7 lux ($0.5{\sim}1.1\;lux$) at night. The variation of the gathering rate of fish in illumination time was small and comparatively fluctuated with stability.

In Korea, the evolution of welfare for people with disabilities can be divided largely four stages. The first phase is before 1981, the second is from 1981 to 1988, the third is from 1989 to 2006 and the fourth phase is from 2007 to now. In the first phase people with disabilities were considered as ones of charity. In the second period the welfare ideal for people with disabilities was appeared. In the third, the framework of welfare system for people with disabilities was formed and welfare services began to be expanded. The fourth phase has been the time to secure human right and social services for people with disabilities. In Korea, for people with disabilities, 2007 was the year of historical turning point. "The Act of Prohibition on Disability Discrimination and Remedy for Right"was built that year and became effective the next year. Also "The Special Education Act for People with disabilities" was enacted newly. "The Disabled Welfare Act" was amended for the change of welfare paradigm. The change is introduction of Independent Living. After 2007 Korean legal systems for people with disabilities have been improved largely.

The tilting train is able to tilt its body towards the center of the turning radius, preventing roll-over of the train as it runs on a curved rail at high-speed. This train, widely accepted for commercial purpose internationally, is very beneficial in that the operating time is shortened without much capital investment to the infrastructure where there are many curved rails. Over several years, the Korea Railroad Research Institute (KRRI) has developed such a train. In this paper, the safety of the Korean tilting train express (TTX) is investigated using a dynamic simulation model. Since proper safety standards have not been established for the TTX, those for the Korean train express (KTX) is employed to analyze the safety and ride comfort of the TTX. This study is useful in predicting the behavior of the TTX and ride comfort, and conforms that designed TTX is stable enough to satisfy the safety standards. It would be useful to recommend proper normal operating speed and determine the maximum safety speed, according to the result. Furthermore, it would be possible to provide basic reference data when analyzing the dynamic effect of the catenary system and the fatigue of the bogie.

Hangang Artpark construction is an enterprise founded in 2018 that involved installing public artworks created by 37 different people (teams) in Hangang Park located in Yeouido and Ichon Park. An iconic public space in Seoul, Hangang Park is turning into an even better public space due to the efforts to change the park into an eco-friendly, cultural-artistic space in tandem with the change in times. The objective of the Hangang Artpark construction business is to augment the environmental and scenic value of Hangang not only to provide a space for leisurely activities but also to revive it as a cultural-artistic area. This is a study of the concept and the design and installation processes of "Thinking of each other", a project by the Hangang Artpark construction business. This art piece has been installed in the wetlands and it trails along Ichon Hangang Park, which was created during the environmental recovery project. The piece consists of sculptures molded into animal shapes that are unique to the location and ecology of the area, displayed in harmony with the park's street furniture. By showing the coexistence of animals that existed in Hangang in the past along with the current inhabitants and the natural enemies of these inhabitants, the piece displays an ecofriendly scene. Moreover, by incorporating this piece into the street facilities of the park, such as gazebos, streetlights, surveillance cameras, and perches, the piece exhibits a different kind of street view compared to the installation style of other conventional environmental artworks. The various sculptures are installed along with the street facilities throughout the trail, rather than in a specific location intended for artworks, thereby achieving harmony with the park scene. In so doing, the piece elicits in the beholder an environment-friendly way of thinking, and at the same time, gives them a sense of calm and pleasure. Further, the paper researches the methods of safely installing art pieces in public spaces and of maintaining these installations.

The purpose of this study is to provide a fundamental data and establish policies for the utilization of closed schools in Korea. The closed schools have been increased in Korea because not only the birth rate, and the number of students have been decreased, but also a greate number of people have moved to big cities or the elderly population is increasing. In this context, this research explores the current circumstance of Japan where experienced the similar phenomenon before Korea had. The results of this study are summarized as follows: The reason for the closed schools in Japan is a decrease in population due to the urbanization and reducing students themselves by aging. The recycling proportion of the closed schools is only approximately 62% in Japan. It means that fewer facilities have been recycled due to the transfer of the managemental departments and the lack of budgets for purchasing the closed schools. As the number of children decreases, but elderly people increases as the same time, it is necessary to positively examine the transition of the closed schools to new facilities for the elderly people. Even though the number of children had been declined, and it is recently turning back to an increasing of the residential children in 23 districts of Tokyo, there are still existing many closed schools. This phenomenon is caused by the decrease of the children and residential areas due to the aging and urbanization. For these reasons, there are many diverse demands for the practical and valuable recycling of the closed schools. However, it seems that there are few cases of successful disposal or transfer of management to other suitable ministry. Therefore, it is necessary for the closed schools to be remodeled the facilities required by current residents.

Ground displacements caused by the construction of overlapping twin shield tunnels with small turning radius are complex, especially under special geological conditions of construction. To investigate the ground displacements caused due to shield machines in the unique calcareous sand layers in Israel for the first time and determine the main factors affecting the ground displacements, field monitoring, laboratory geological analysis, theoretical calculations, and parameter studies were adopted. By using rod extensometers, inclinometers, total stations, and automatic segment-displacement monitors, subsurface tunneling-induced displacement, surface settlement, and displacement of the down-track tunnel segments caused by the construction of an up-track tunnel were analyzed. The up-track tunnel and the down-track tunnel pass through different stratum, resulting in different construction parameters and ground displacements. The laws of variation of thrust and torque, soil pressure in the chamber, excavated soil quantity, synchronous grouting pressure, and grout volume of the two tunnels from parallel to fully overlapping orientations were compared. The thrust and torque of the shield in the fine sand are larger than those in the Kurkar layer, and the grouting amount in fine sand is unstable. According to fuzzy statistics and Gaussian curve fitting of the shield tunneling speed, the tunneling speed in the Kurkar stratum is twice that in the fine-sand stratum.

This study is about the periodic characteristics of Wonsam in the Joseon Dynasty. Wonsam include the Danryeong-shaped Wonsam in the beginning, the compound Wonsam in a period of transition and the stereotyped Wonsam in the late Joseon Dynasty. The formative characteristics of Wonsam are divided into four stages. The first stage of the Wonsam is from the 15th to 16th century. The shape of Wonsam began to form and it was similar to one of Danryeong during this time. The formative characteristics of the first Wonsam included collars that looked like one of Danryeong, side pleats(called Moo) with multiple inner folds, straight cylinder-shaped sleeves, and a belt tied with the Wonsam. There were various fabrics that were used for the Wonsam from this stage. Second stage of the Wonsam is from the early 17th to mid 17th century. This period marked the beginning of the transition of the Wonsam and it served as a stepping-stone to the development stage in the Joseon Dynasty. The characteristics of the transitional Wonsam were a complex combination of the Danryeong and Wonsam. During this period, the Wonsam went through many changes and forms in a short period of time. Third stage of the Wonsam is from the mid 17th to early 19th century. The Wonsam was developed at this stage. The developed Wonsam went through a period of transition equipped with a stable form. The formative characteristics of Wonsam during this period included collars that faced each other, big and wide sleeves with multicolored stripes, Hansam, curve-edged side seam and the side pleats(Moo) with multiple inner folds had disappeared. It was a turning point from the single-layered clothes to double layered clothes and from dark blue to green color appeared at this time. The fabric patterns of this stage tended to consist of more simplified silk pattern. The fourth stage of the Wonsam is from the late 19th to 20th century. The Wonsam was expanded at this stage. The formative characteristics and fabrics were typically used for the standard Wonsam and were divided into two types; as a ceremonial robe used in courts and a wedding ceremonial robe for the common people. Phenomena such as sewing of double-layered clothes as one and straight-edged side seam during the late Joseon period developed into simpler and more practical fashion culture.
