This study was for suggesting the test methods in the revision process of the cataloging rules to understand the problem of draft cataloging rules and to apply the new cataloging rules correctly in libraries instead of collecting the opinions by the traditional seminar and conference in the process of revising KCR, KCR2, KCR3, KCR4. For this study, the literature review and the case study were used as the research methods. The case study was based on the US RDA Test by US RDA Test Coordinating Committee. The evaluation areas of the test were cataloging rules, record creation and system development by reflecting the new cataloging rules, user, and cost. The data for the analysis was the creation of bibliographic records and authority records by librarians, and the question investigations that were the use of institutions, librarians, and users. This study would contribute to revise the cataloging rules in future by analyzing the errors of applying new rules to bibliographic record and by investigating the difficulties of applying rules in completing the bibliographic record. Also, the libraries could be easy to decide to implement the new rules from the creation time of bibliographic record by new rules and the learning curve of new rules.

The rapid increase in the consumption of products that contain rare metals has highlighted the importance of recycling and recovering resources from these products when they enter the waste stream. Among various metal resources that can be recovered, this study analyzes the waste streams of cobalt and palladium to determine how their waste resource circulation can be improved at each stage of the waste stream. The findings of this study point to improvements and strategies that can be made at individual stages. First, at the discharge/import stage, the implementation of tariff quotas for specific recycled metal resources is suggested to allow the systemic categorization of waste metals as resources. At the collection/discarding stage, a major problem is the instability in the supply of scrap metals, which may be better managed by changing the bidding process for the scrap metals. At the pretreatment stage, possible areas for improvement are uncovered concerning technical areas, such as technological development and improving the efficiency of material recycling, as well as policy-wise, for instance, expanding the regulation for manufacturers to produce products that are designed to facilitate resource recovery, increasing incentive for closed recycling, and refining the guidelines and standards for recycling. At the resource recovery stage, as the waste metal recycling industry consists of businesses that vary in size, policies to promote cooperation and coexistence between large and smaller enterprises will benefit the industry in the long-run. Lastly, at the product production/export stage, a tariff on exporting waste resources that contain cobalt and palladium will help control the amount of waste metals that are shipped abroad.

There are ATC (Automatic Train Control), ATP (Automatic Train Protection), ATS (Automatic Train Stop) and ATO (Automatic Train Operation) etc. in train control systems. As various train control systems are installed according to sections, on-board signaling systems are installed to apply to the section. Hence, operation flexibility of trains is decreased. In other words, when trains are operated in the section where other train control systems are used, the on-board signaling systems are changed. Recently, a study on the combined on-board signaling system has been researched to solve this problem. The combined on-board signaling system consists of ATC, ATP and ATS device. Because the train control systems are vital, it needs to design the combined on-board signaling system by using k out of n system. In this paper, when k out of n system is applied in the combined on-board signaling system, the reliability and loss cost are analyzed by using failure rate in each device. Hence, the ideal number of systems is presented according to the number of outputs.

The purpose of this paper is to analyze the behavior and to study the safety evaluation of the Unmun Dam located in Cheongdo-Gun of GyeongBuk Province, Korea. For this purpose, soil analyses including boring data, geophysical surveys and monitoring the buried geotechnical gauges, such as pore-pressure gauge, earth-pressure gauge, displacement gauge, multi-layer settlement gauge, leakage flow-meter, were conducted. In addition to these data, numerical analyses of behavior of dam were performed to predict and to compare the data which were obtained from the above methods. Since many defects, such as gravel and weathered rock blocks in the dam core, and lots of amounts of leakage, by boring analyses were found, reinforcement by compaction grouting system (CGS) has been conducted in some range of dam. Some geotechnical gauge data were also used to confirm the effects of reinforcement. Analyses of monitoring the data of geotechnical gauges buried in the dam, such as pore-pressure gauge, earth-pressure gauge, displacement gauge, multi-layer settlement gauge, and leakage flow-meter shows the load transfer of dam and the possibility of hydraulic fracturing. As a conclusion, some problems in the dam found. Especially, the dam near spillway shows the high possibility of leakage. It should be pointed out that only the left side of he dam has not a leakage problem. As a whole, the dam has problems of weakness, because of unsatisfactory construction. It is strongly recommended that highly intensive monitoring is required.

The purpose of this paper is to analyze the behavior and to study the safety evaluation of the Unmun Dam located in Cheongdo-Gun of GyeongBuk Province, Korea. For this purpose, soil analyses including boring data, geophysical surveys were conducted. In this paper, especially many geophysical methods were adopted to configure out the subsurface situation of dam. Applied geophysical methods were: 1) electric resistivity survey, 2) high frequency magnetotelluric (HFMT) survey, 3) ground penetrating radar (GPR) survey, 4) seismic refraction survey, 5) seismic cross-hole tomography survey, and 6) high frequency impedance (ZHF) survey. Each of geophysical surveys were analyzed and joint analyses between geophysical surveys were also performed to deduce the more reliable subsurface information of Dam by using the features and characteristics of each geophysical survey. Since many defects, such as gravel and weathered rock blocks in the dam core, and lots of amounts of leakage, by boring analyses were found, reinforcement by compaction grouting system (CGS) has been conducted in some range of dam. Some geophysical data and data of geotechnical gauges were also used to confirm the effects of reinforcement. Electric resistivity, EM, GPR, ZHF, seismic refraction and seismic tomography surveys show that left side of dam is weak, which means the possibility of existence of gravel, rock block, water and cavities in the core of dam. This result coincides with the boring data. Especially, electric survey after reinforcement shows that even the right side of the dam has been deformed by the strong pressure during the reinforcement itself. As a conclusion, some problems in the dam found. Especially, the dam near spillway shows the high possibility of leakage. It should be pointed out that only the left side of he dam has not a leakage problem. As a whole, the dam has problems of weakness, because of unsatisfactory construction. It is strongly recommended that highly intensive monitoring is required.

Coarse resolution (9 - 50 km pixels) Sea Surface Temperature satellite data are frequently considered adequate for open ocean research. However, coastal regions, including coral reef, estuarine and mesoscale upwelling regions require high-resolution (1-km pixel) SST data. The AVHRR SST data often suffer from navigation errors of several kilometres and still require manual navigation adjustments. The second serious problem is faulty and ineffective cloud-detection algorithms used operationally; many of these are based on radiance thresholds and moving window tests. With these methods, increasing sensitivity leads to masking of valid pixels. These errors lead to significant cold pixel biases and hamper image compositing, anomaly detection, and time-series analysis. Here, after manual navigation of over 40,000 AVHRR images, we implemented a new cloud filter that differs from other published methods. The filter first compares a pixel value with a climatological value built from the historical database, and then tests it against a time-based median value derived for that pixel from all satellite passes collected within ${\pm}3$ days. If the difference is larger than a predefined threshold, the pixel is flagged as cloud. We tested the method and compared to in situ SST from several shallow water buoys in the Florida Keys. Cloud statistics from all satellite sensors (AVHRR, MODIS) shows that a climatology filter with a $4^{\circ}C$ threshold and a median filter threshold of $2^{\circ}C$ are effective and accurate to filter clouds without masking good data. RMS difference between concurrent in situ and satellite SST data for the shallow waters (< 10 m bottom depth) is < $1^{\circ}C$, with only a small bias. The filter has been applied to the entire series of high-resolution SST data since1993 (including MODIS SST data since 2003), and a climatology is constructed to serve as the baseline to detect anomaly events.

As public attention on Well-being culture increases, it is now considered to be a new trend of modern society. The purpose of this study is to publicize the necessity of design products which are advanced in quality and encourage the use of it. The researcher judged that study on design of lighting product to adopt well-being trend is in preliminary level and aims to research on the tendency of well-bing trend and lighting design which the consumer of this age is demanding. As the result of changes in modern consumption trend, design is considered to be a factor of capricious cultural phenomenon. In addition to this, as high technology such as ubiquitous develops with the degitalisation and informatization, the consumer are paying attention to dynamic products rather than static products or products which respond to external stimulus. Products which adopt well-being trend pursuing nature friendly life are particularly preferred It means that not only the basic function of products but also design which satisfy the five sense is required. Modern consumers use products in various way. However, the pro-environmental and human-centered tendency is tried only in very limited area and general study on this matter is extremely rare. This study analyzes the factors which intercepts the adoption of well-being trend to lighting products and seeks for an alternative to solve the problem. Interaction design with well-being trend was adopted to lighting design and the result presented that there is a possibility to differentiate existing lighting design by adding interaction design to the existing lighting design. Therefore, the need for further study on this matter is presented.

There are very few numbers of 115K FPP (Fixed Pitch Propulsion) Tankers for the Baltic ice class IA because the minimum power requirement of FMA (Finish- Swedish Maritime Association) needs quite large engine power and the 40 m Beam is out of calculation range of FMA minimum power requirements. The shipyard has no choice except to increase the engine power to satisfy FMA minimum power requirement Rule. And the operation cost, efficiency of hullform and its building cost are not good from the ship owners' point of view To solve this problem, the experience of ice breaking tanker development and the ice tank test results were adopted. The main idea to reduce the ice resistance is by reducing waterline angle at design load waterline. The reason behind the main idea is to reduce the ice-clearing force. Two hull forms were developed to satisfy Baltic Ice class IA. Two ice tank tests and one towing tank test was performed at MARC (Kvaener-Masa Arctic Research Center) and SSMB (Samsung Ship Model Basin) facilities, respectively. The purpose of these tests was to verify the performance in ice and open water respectively The hull form 2 shows less speed loss compared to Hull form 1 in open water operation but hull form 2 shows very good ice clearing ability. finally the Hull Form 2 satisfying Baltic ice class IA. The merit of this hull form is to use the same engine capacity and no major design changes in hull form and other related designs But the hull structure has to be changed according to the ice class grade. The difference in two hull form development methods, ice model test methods and analysis methods of ice model test will be described in this paper.

Objectives : In order to comprehend and utilize external therapy, we considered that we needed to research Wu Shi-Ji who was a medical specialist of external therapy. We looked at the special study on external therapy in his book, ${\ll}li-yao-pian-wen{\gg}$, especially ; in this part his generai approach to external therapy was well-detaiied. Methods : We translated and analyzed . Results : In , he gives a supplementary explanation about the insufficient attention paid to external therapy, 膏(gao) - (ti) 坐(zuo) (yu) 抹(mo) 纏法(chan fa), through San Jiao(三焦). And he insisted on his conception of external therapy: ointment(膏) and the moth of sneezing, sitting on herbs(坐), steaming or attaching herbs patients's navel, rubbing(抹) and binding(縛), based on ${\ll}nei-jing{\gg}$ and ${\ll}shang-han-lun{\gg}$. He put forward the general rules of external therapy using those methods. And through , he explained that the efficacy of his external therapy was basically the same as internal therapy and medicine, the only difference was in the method. In addition, this external therapy has some merits when compared with internal medicine. First, it's easier to diagnose a disease and treat patients compared to internal medicine. For instance, when a patient has a problem with his abdomen, we just have to diagnose a disease of the abdomen and treat using one method of external therapy on the abdomenal area. Second, external therapy has fewer side effects. And third, we can utilize the meridian theory when we use external therapy. Conclusions : Through , we basically understood his conception of external therapy. Although more research is needed, we suggest that we need to enlarge our usage of external therapy, not just confine ourselves to smaller areas of focus. His point of view suggests that external therapy is not merely an adjunct to internal therapy, but an interdependent course of study and action in its own right.
