The recent trend in tourism souvenirs has shifted from traditional products to modern, practical, and budget oriented products. As a result, tourism souvenirs that meet the changing demands of consumers need to be studied and developed. Aprons are one of the most important accessories worn for housework, and are also an important part of uniforms worn at restaurants and hotels. As a result, aprons typify the characteristics of makgeolli - practical products that meet the needs of modern consumers. Therefore, the development of tourism souvenirs targeting tourists that seek Jeonju Makgeolli is expected to bring substantial social and economic benefits. The purpose of the study is to develop designs for aprons for promotional and tourism souvenirs for the Jeonju Makgeolli Research Center. The research has been conducted with a survey on design preferences of aprons, design proposals, production of actual aprons, and selection of the final design. The study is empirical in nature and realistic in scope since it is anticipated that the trial and manufacture of aprons will be commercialized as tourism souvenirs. It is expected that aprons, which can be produced at low cost, will meet the needs of recent consumers who prefer elegant, modern, and practical goods as compared to simple and bland folk crafts or traditional products. More studies and research on the development of designs of aprons as tourism souvenirs is expected to be conducted based on this study.

This study showed that numerical simulation can be effectively used to analyze discharge capacity according to the form and arrangement of the lock gate of a tidal power plant. For the numerical simulation, FLOW-3D with Reynolds-averaged Navier-Stokes equation as a governing equation was used. This study found that improvement of apron length and approach angle of guide wall of the lock gate causes differences in discharge capacity of $10\%$ or more. In addition, there was a difference of discharge capacity caused by the connecting structures of the drainage gate and hydraulic turbine structure and the side slope at the end of apron. This study also showed that hydraulic investigation to enhance a discharge capacity is needed when the lock gate is designed and that numerical model experiments can be a useful analysis tool to design the drainage structure, as well as the hydraulic model experiment.

Purpose: This study aimed to investigate the level and related factors related to health-promoting lifestyle in operating room nurses in Korea. Method: A cross-sectional descriptive survey design was employed. The data were collected using questionnaire for three weeks in December 2018 from 110 operating room nurses working for more than six months in a general hospital located in Seoul. The Health Promoting Lifestyle Profile-II, The Korean Version of the Practice Environment Scale of Nursing Work Index, and Operating nurse's Job stress Factor Scale were used. Results: Significant relationships were observed between health promoting lifestyle and educational level(p= .025), perceived economic status (p= .001) wearing a lead apron for protection from radiation during the operation(p< .001), work satisfaction(p= .016), and fatigue related to work(p= .006). Also significant correlations were identified between nursing work environment and health promoting lifestyle. However, the health promoting lifestyle was not statistically different based on occupational stress(p= .365). In multiple linear regression analyses, the level of health promoting lifestyle found to be higher in subjects who did not wear a lead apron for protection from radiation(p= .017), and who had more positive perception of the nursing work environment(p= .034). Conclusion: In order to increase health promoting lifestyle of operating nurses, the strategies to improve the nursing work environment are essential.

The purpose of this study is to classify the factors influenced on the damages of head works suffered from the storm flood occurred on July 22 1980 in both Musim and Bochong rivers and to find out an integral counter measures against the causes influenced on the disaster of head works in the engineering aspect of planning, design, construction and maintenance. In this survey, number of samples was taken 25 head Works, and the counter measures against the causes of their disasters summarized was as follows, 1. In the aspect of planning a. As the flood water level after the establishment of head works is more increased than the level before setting of head works owing to having more gentle slope of river bed between the head works than nature slope of river bed. Number of head works should be reduced for the appropriate annexation of them b. In the place where head works is established on the curved point of levee, the destruction of levee becomes severe by the strong deflective current. Therefore the setting of head works on the curved point should be kept off as long as possible and in case of unavoidable circumstances the construction method such as reinforced concrete wall or stone wall filed with concrete and anchored bank revetments should be considered. 2. In the aspect of design a. As scoring phenomena at up stream is serious around the weir Where the concentration of strong current is present in such a place, up stream apron having impermeability should be designed to resist and prevent scoring. b. As the length of apron and protected bed is too short to prevent scoring as down stream bed, the design length should be taken somewhat more than the calculated value, but in the case the calculated length becomes too long to be profitable, a device of water cushion should be considered. c. The structure of protected river bed should be improved to make stone mesh bags fixed to apron and to have vinyl mattress laid on river bed together with the improvement for increasing the stability of stone mesh bags and preventing the sucked sand from the river bed. d. As the shortage of cut-off length, especialy in case of the cutoffs conneting both shore sides of river makes the cause of destruction of embankment and weir body, the culculation of cut-off length should be taken enough length based on seepage length. 3. In the aspect of design and constructions a. The overturing destruction of weir by piping action was based on the jet water through cracks at the construction and expansion joints. therefore the expansion joint should be designed and constructed with the insertion of water proof plate and asphalt filling, and the construction joint, with concaved shape structure and steel reinforcement. b. As the wrong design and construction of the weep holes on apron will cause water piping and weir destruction, the design and construction of filter based on the rule of filter should be kept for weep holes. c. The wrong design and construction of bank revetment caused the severe destruction of levee and weir body resulting from scoring and impulse by strong current and formation of water route behind the revetment. Therefore bank revetment should be designod and constructed with stone wall filled with concrete and anchored, or reinforced concrete wall to prevent the formation of water flow route behind the wall and to resist against the scoring and impulse of strong stream. 4. In the aspect of maintenance When the damaged parts occurred at head works the authorities and farmers concerned should find and mend them as soon as possible with mutual cooperation, and on the other hand public citizen should be guided for good use of public property.

Based on an investigation of Miao ethnic group costumes, this research focuses on redesigning and reinterpreting of the Miao costume. The results are summarized as follows. According to the constitution of the clothes, the decorative parts and the way people wear them, women's clothing can be divided into five categories: Sangseohyeong, Geomjungnamhyeong A, Geomjungnamhyeong B, Cheongeomjeonhyeong, Haenamhyeong. Miao consists of straight lines with creases for both skirts and trousers. With the excess part of the belt or apron, X-shape and H-shape are formed. There are three basic decorative patterns: geometric patterns, animal patterns and plant patterns. In addition, there are three color values: warm, cool and dark. Silver Jewelry plays such an important role in the Miao Costume that the process of the production is also very special for the Chinese national dress. According to the features of the five types of Miao, then redesign and re-interpreted of them.

Protective clothing developed for rose flower farmers has been evaluated to improve the working conditions. The requirements of rose farmers were first identified to design protective clothing for farmers working with thorny plants. A fit test was conducted to assess the thermal comfort and protective function against thorn pricking to compare and evaluate the usability of developed experimental clothing with existing working clothes. Based on the survey results of rose farmers' requirements, protective clothing was designed in the form of an apron (which was the most preferred after gloves) with a pattern designed for the production of experimental clothing. For the developed protective clothing, the strap and buckle closure method was selected to open the back of the body as much as possible; in addition, sleeves were made in the attachable form of a half-sleeve to protect the arms from the thorns. The fit test of the developed protective clothing and existing working clothes revealed the temperature and humidity inside the developed protective clothing to be significantly different in the back compared to existing work clothes. In addition to thermal sensations, the subjective humidity sensations were statistically significant different in the developed protective clothing compared to existing work clothes. The subjective protective function for thorn pricking was also found to be satisfactory.

To insure the safety of the drainage sluice, topogrophical change due to erosion as well as capability of discharging the design flow in a very important factor. In consideration of the fact that the drainage sluice is built in the sea, its construction has many topographically restricted problems and naturally requires a completeness of research and experiment. This thesis is a comparative and analytic study of discharging flow acting on the erosion at the bottom of the structure on the basis of the measured velocity on the downstream channel of the drainage sluice. (1) The measured velocity shows a little higher values than the computed velocity, because the measured velocity was observed at the surface of the stream. There fore, it is reasonable that the compated velocity should be taken in this study. (2) The field observation was conducted to have the measurement of the flow velocity without surveying the area of flow. Therefore, the coefficient of discharge could not be computed. The survey of the area of flow is planned to be conducted along with the measurement of the flow velocity. (3) The apron of the drainage sluice is free discharging type and it was designed to be about 80m in length less than it should be. (4) The apron of free flow discharging type should have a solid foundation to protect the structure by preventing erosion damage to upstream and downstream channels against weathering of rock and strong torrent. Whether free flow discharging type or energy-dissipating type is best chosen depends on the topographical condition of the forage site, therefore, there would be a comparative study before the final decision was made about the protrection for the structure. (5) It is considered to be appropriate that the design and construction of the drainage sluice should have a complete study which is based on hydraulie model test before the type of protection is decided. (6) It is much requested that a variety of experiment equipments be installed and observed to study the protection for the drainage sluice.

Scour hole is formed due to the high shear stress of the jet flow at the outlet of a hydraulic structure and vortex erosion occurs in the scour hole. It is important to determine the amount of vortex erosion occurs in the scour hole. It is important to determine the amount of vortex erosion for the design of bed protection. If the vortex erosion continues and reaches to the hydraulic structure, it causes the deformation of the structure itself. To obtain the amount of the vortex erosion, it is necessary to determine the shear velocity of the line vortex in the scour hole was derived by the theory of energy conservation and found to be related to the upstream overflow velocity. The amount of vortex erosion from the scour hole was obtained using entrainment equation for given value of shear velocity. For a design purpose, if the flow velocity at the end of an apron and the properties of bed material are given, the amount of vortex erosion was obtained.

The modern trend in costumes, influenced by postmodernism, is to use of various patterns and images borrowed from diverse cultures of many ethnic groups. The Yo tribe studied in this paper is miner ethnic group in China, whose traditional costume is very splendid and modern. In addition, its embroidery pattern has a high artistic value in that its shapes are diverse and splendid and each one has its own peculiar elegance. As for the research method, I examined the Yo tribe's history, culture, traditional costumes and design patterns through related books, research papers, internet sites, and etc. The results of the paper are as follows. The Yo tribe's costumes consist of a jacket, trousers or a skirt, an apron and a belt. Although the color of the costumes is all black, there are splendid embroidery decorations with the colors of red, orange, yellow, green and white on the chest or shoulder part of a jacket, the adjusting lines, cuffs, or a part of a trousers and aprons. The types of the patterns represented in the Yo tribe's traditional costumes are related to nature, ancestor worship, ethnic legends, history, religion, and agricultural lives. The method by which the Yo tribe expressed on their costumes is a "peach-blossom" technique, which uses cross-shaped embroidery with wrap and woof threads. Because it is not apt to express delicate and detailed patterns, the Yo tribe's patterns tend to show abstract and geometrical forms.

The purpose of this thesis was to design and develop restaurant uniforms for Yeosu and Suncheon-City using local cultural resources by investigating the present situation of restaurant uniforms. The study was conducted through literature review and practical research on uniform designs. The practical research included investigating and analyzing the recent uniform designs of 60 spots in both cities and the preference of local cultural resources, finally suggesting eight restaurant uniform designs and four original samples. It was found that most workers in both cities wore shirts and pants or aprons as uniforms and also that the restaurant uniforms had many problems, such as poor designs, functionality, and the lack of local characteristics. According to these results, a design concept called 'Colorful Night Sea' was built for Yeosu using a design motive of a Yeosu Expo symbol, a Big-O Show shape, and Dolsan Gat flowers. For Suncheon-city, a design concept called 'A Rural Landscape' was built using a design motive of Nagan Eupseong and a field of reeds in Suncheon Bay. The restaurant uniform items included a top (shirt or blouse), pants, apron, and headdress in both cities. This study is meaningful as it helped improve the local image and economic situation, by proposing distinct uniforms designed by using local cultural resources.
