The role of the turnouts installed on the points of railway branches and intersections is to safely switch the directions of trains. In case of abnormal forces applied to the turnouts due to extreme operating conditions, it is difficult in the current system to conduct accurate diagnosis and measuring. Moreover, the existing measurement devices for turnout switching power are mostly based on foreign technologies, which provide only limited information on the switching power; this information is insufficient for effective monitoring and maintenance. In this paper, through an analysis of the characteristics of the switching and locking function, the problems in turnout power measurements of current electrical point machines in Korea are examined. And based on the results, a new sensor-based method for measuring switching power is proposed.

In order for a financial company to collect personal information, it explicitly notifies consumers of the contents stipulated by law and gets consent beforehand. As a result, as financial products became more complicated and diverse, and the contents of 'Consent form for providing personal information' became more complicated and more. In particular, in the case of internet or mobile, the letter became smaller as the screen size limit, making it more difficult to understand. This is because almost all companies that collecting personal information are in a similar situation, In the position of consumers who use services are, contradictions arise that habitually agree without understanding the consent contents. In this research, in order to present a consent policy establishment decision-making model to rationally collect and use personal information through the Internet website of financial companies, consider the domestic and foreign legal system Then, derive a problem To present improvement measures. In addition, the evaluation factors selected through the research are verified by presenting decision making models and formulas using AHP (Analytic Hierarchy Process) method.

In this study, questionnaire were made to environment-friendly producers of apples regarding farm management methods in low-input production method. utilizing organic materials, production and marketing of apples with lower agricultural chemical residues. Besides, five apples farms were visited to find out their management situation by employing the low-input production method in order to protect the environment as well as consumer's health. Those five low-input apple farms were scattered in Kyungbuk, Chungnam, and Chonnam Provinces, There were not many low-input apple farms across the nation from the beginning and, as a result, increasing the sample size was basically very difficult. Most of these farms were using 140hrs of labor per 10a, of which 30hrs in pre-season management, 25hrs in plowing and weed control, 15hrs in disease and pest control, 20hrs in harvest and marketing and 50hrs in miscellaneous activities. Relatively, pest control takes much time in that they would spray pesticides 7-10 times a season to control the apple disease, 9 times on the average. The average gross revenue of low-input apple farms was about \2,000,000/10a, and their average yield was 2,000kg/10a, which are 25% and 13% lower, respectively, than the ordinary apple production case. This means the low-input farmers are inefficient in marketing their products. On the other hand, their production costs were 20.4% higher than the ordinary apple farms on the average. Since the imported foreign fruits including apples must use various agricultural chemicals on their way to the export markets, the domestic low-input apples have competitive edge over them in therms of food safety. In order to improve the low-input apple industry, active cooperation is needed among the producers, government and researchers more than ever. Among other things, production cost reduction and quality improvement with lower chemical residues are part of the urgent matters to be done.

Wheel bearings are important automotive parts that bear the vehicle weight and translate rotation motion; in addition, their seals are components that prevent grease leakage and foreign material from entering from the outside of the bearings. Recently, as the need for electric vehicles and eco-friendly vehicles has been emerging, the reduction in fuel consumption and $CO_2$ emissions are becoming the most important issues for automobile manufacturers. In the case of wheel bearings, seals are a key part of drag torque. In this study, we investigate the prediction of the drag torque taking into consideration the hyperelastic and viscoelastic material properties of automotive wheel bearing seals. Numerical analysis based on the finite element method is conducted for the deformation analyses of the seals. To improve the reliability of the rubber seal analysis, three types of rubber material properties are considered, and analysis is conducted using the hyperelastic material properties. Viscoelastic material property tests are also conducted. Deformation analysis considering the hyperelastic and viscoelastic material properties is performed, and the effects of the viscoelastic material properties are compared with the results obtained by the consideration of the hyperelastic material properties. As a result of these analyses, the drag torque is 0.29 Nm when the hyperelastic characteristics are taken into account, and the drag torque is 0.27 Nm when both the hyperelastic and viscoelastic characteristics are taken into account. Therefore, it is determined that the analysis considering both hyperelastic and viscoelastic characteristics must be performed because of its reliability in predicting the drag torque of the rubber seals.

Objectives: This study aims to review the herbal medicines containing substances banned by World Anti-Doping Agency(WADA), and to consider criteria for the using of herbal medicines. Methods: Using foreign(Pubmed, Cochrane, Embase, Google Scholar, WANFANG, CiNii) and domestic databases (NDSL, OASIS, RISS), we analyzed the content and pharmacokinetics of the prohibited substances in herbal medicines. Results: Herbal medicines containing the prohibited substances proposed in Korea, China, and Japan are Ephedrae Herba, Cannabis Semen, Strychni Semen, Strychni Ignatii Semen, Pinelliae Tuber, Rhizoma Pinelliae, Chelidonii Herba, Papaveris Fructus Deseminatus, Liriopis Tuber, Rehmanniae Radix Recens, Cistanchis Herba, Ponciri Fructus Immaturus, Aurantii Fructus Immaturus, Moschus, Testudinis Plastrum, Otariae Testis et Penis, and Hominis Placenta. Of these, when using Ephedrae Herba, Cannabis Semen, Strychni Semen, Moschus, Strychni Ignatii Semen, and Otariae Testis et Penis, caution is needed in relation to the doping test. Other herbal medicines are considered safe for the doping test. In addition, by analyzing data related to higenamine added to the WADA's prohibited list of doping since 2017, we don't recommend using Nelumbinis Plumula. And in the case of the other herbal medicines containing higenamine, it is considered that care should be taken in doping test depending on the amount of usage. Conclusions: As a result of analyzing the herbal medicines which are in prohibited list about doping, we were able to know the criteria and precautions to use when prescribing the herbal medicines. Further research will be needed about common used herbal medicines and the amount of detection depending on extraction and boiling method.

The share of the internet has grown significantly in terms of usage and level of influence. Among the internet media, OhmyNews is considered a alternative media representing Korea's independent internet news, and a typical example displaying characteristics of the internet news. The processing step can be divided as five stage, with recorded information and applicable technical element extractable from each stage. In this thesis paper, we have analyzed domestic and overseas metadata standard examples to devise metadata design plans. Items to be focused when redesigning metadata based on domestic and foreign case studies are as follows: First, user access should be convenient; second, connection with related information should be considered; third, accumulation of production, management, usage, storage, and action history should be considered; and fourth, the design should allow higher utilization of contents. In depth researches over internet media are already being carried out in external academic disciplines including the media information studies, information and communication studies, and communications studies. We expect that it will also be necessary to consider such researches over the internet media for mass media record management research going forward.

The banking system provides a number of important functions for the economy and is also the lifeblood and financier of the economy in each country. Large amounts of idle money have not been exploited by banks; however, banks still depend on loans, including loans from foreign banks, to meet the growing demand, as such, for banks, the cost of capital is high, the stability and business efficiency are low and banks have not promoted their internal resources to grow steadily. To achieve the goal, this research analyzes the factors affecting the choice of bank for the deposit decisions of customers in Vietnam. The study used a sample data of 250 individuals and SPSS software was used to analyze the data. The results showed that customer policy has a positive effect on customers' deposit decisions in a bank, and this is new evidence regarding behavioral theory in the case of Vietnam. Results further demonstrated that other factors such as employee image, brand, interest rate, relative influencing, and transaction time positively impact the choice of bank for the deposit decisions of customers. However, the bank's promotion strategies had no impact on the choice of bank for the deposit decisions of customers. Besides, employee image is the most influential factor in the deposit decisions, followed by the bank's brand and interest rate.

This paper considers a problem to find a set of intervals containing all the points for the given n points and m intervals on a line, This is a special case of the set cover problem, well known as an NP-hard problem. As optimization criteria of the problem, there are minimizing the number of intervals to cover the points, maximizing the number of points each of which is covered by exactly one interval, and so on. In this paper, the intervals have weights and the sum of weights of intervals to cover a point is defined as a membership of the point. We will study the problem to find an interval cover minimizing the maximum of memberships of points. Using the dynamic programming method, we provide an O(m²)-time algorithm to improve the time complexity O(nm log n) given in the previous work.
