The purpose of this research is to assess the need for wedding etiquette training for couples in order to provide basic educational materials for brides and grooms-to-be. This survey consisted of 43 questions. The questions pertaining to the need for wedding etiquette training were measured using the 5-point Likert scale. The survey was conducted between September 1st, 2011 and December 1st, 2011. The research subjects consisted of 230 brides and grooms-to-be. Questionnaires were analyzed by frequency analysis, F-test, t-test, and correlation analysis using SPSS/win17.0. Based on our findings, we would like to make the following proposals and conclusions. First, as the importance of a wedding education program could be ascertained, educational demands need to be gathered and applied to the operation of such programs. The education and training programs need to be activated by wedding preparation education centers or the Health and Family Support Center, on weekends or week nights 3 months prior to a couple's wedding ceremony. Second, wedding etiquette training content needs to be included in existing education programs that primarily focus on helping couples adapt to married life. Such training content should specifically include the etiquette of exchanging wedding presents, home life etiquette, etiquette for the formal meeting between the families of the bride and bridegroom, pyebaek etiquette and ham (a box of wedding gifts sent by a bridegroom to his bride before the wedding) etiquette. Third, when examining the particulars of the need for wedding etiquette training, we came to the conclusion that couples should be properly educated about the meaning and value of the wedding presents, pyebaek and ham that are required during traditional wedding ceremonies. Fourth, the need for wedding etiquette training was shown to be higher for women than for men. It was also higher for individuals in specialized fields than for ordinary company employees. Wedding etiquette training programs need to be structured with such considerations in mind. Fifth, when structuring the program for wedding etiquette training, the correlation of the needs for training should be considered. It is necessary to prepare training plans by dividing the program into the following categories: the formal meeting between the families of the bride and the bridegroom, ham and wedding presents, wedding ceremony etiquette, pyebaek, and home life etiquette training.

The purpose of this study is to analyze high school students' understanding levels about earth science terms written in Chinese characters according to learners' characteristics. In order to investigate how the responses vary according to their characteristics, first of all, proper scientific terms are selected, and then corre sponding questions about them are offered as subjects, which consists of a Korean characters type, a picture type, and a Korean and Chinese characters type. During paper test and interview, the questions are given to fifteen students from general high schools in Jecheon, Chungbuk Province. The results of the study are as follows; Students in formal operation level and field-independency answered very well and also the terms of Chinese characters type and picture type improve the students' understanding and memorization. Generally, Chinese characters have more positive influence on their learning than the negative. Therefore, in general, it seems that it's more effective to explain the sound and meaning of terms in detail and to give learners enough time to draw a picture about each term by themselves when scientific terms are delivered to students in Chinese characters in class.

With rapid increasing the development and use of IoT Devices, requirements for safe IoT devices and services such as reliability, security are also increasing. In Security engineering, SDLC (Secure Development Life Cycle) is applied to make the trustworthy system. Secure Development Life Cycle has 4 big steps, Security requirements, Design, Implementation and Operation and each step has own goals and activities. Deriving security requirements, the first step of SDLC, must be accurate and objective because it affect the rest of the SDLC. For accurate and objective security requirements, Threat modeling is used. And the results of the threat modeling can satisfy the completeness of scope of analysis and the traceability of threats. In many countries, academic and IT company, a lot of researches about drawing security requirements systematically are being done. But in domestic, awareness and researches about deriving security requirements systematically are lacking. So in this paper, I described about method and process to drawing security requirements systematically by using threat modeling including DFD, STRIDE, Attack Library and Attack Tree. And also security requirements are described via Common Criteria for delivering objective meaning and broad use of them.

Objectives : To investigate the current status of hospital-based health promotion programs in Korea and to elucidate the factors which affect to the process of implementation. Methods : We conducted a mail survey of all 875 hospitals in Korea from March to May 2001. In reference to 12 specific kinds of health promotion programs, hospital CEOs were asked whether their hospital have such programs, whether they are fully staffed and whether the program is paid for by the patients. Contextual factors(location, hospital type, number of beds, length of operation, public/private status, economic level of the community, the level of competition) and organizational factors (the extent of market, compatibility with vision, formalization), strategic types of the CEOs (defender/analyser/prospector) were also surveyed. The relationships between each variable and the implementation of health promotion services, activation of services, and the target groups(patient/community resident) were analyzed by univariate analysis and the independent effects of these variables were examined with multiple logistic regression. Results : 100 of 125 hospitals responding (84.8%) had mere than one health promotion program. However, they showed fluctuations in the adoption rate of each programs, meaning that comprehensive health promotion services were not provided. Many programs were not fully staffed and few hospitals had paid programs. In factors affecting health promotion service implementation, private hospitals showed a higher rate in implementation than public hospitals. In contrast, when the competition among nearby hospitals was intense, the level of implementation of service lowered. In the strategic type of the CEOs, the prospectors were shown to have instituted more health promotion programs in their hospitals and the analysers had a greater tendency to have programs for community residents than the defenders. Conclusion . Considering the above results, contextual factors may contribute greatly to the introduction of health promotion services in Korean hospital, although the CEO's personal preference and organizational factors play a larger role in the activation of services. Additionally, the CEO's personal preference may be the major influencing factor in the introduction of programs for community residents.

The sensorless control based on the flux linkage of PM synchronous motors has excellent position estimation characteristics at low speeds. However, a limitation arises because the integrator of flux estimator is saturated by the DC offset generated during the analog to digital conversion(ADC) process of the measured current. In order to overcome this limitation, HPF with a low cutoff frequency is used. However, the estimation performance is deteriorated (Ed- the verb deteriorate already includes the meaning of 'problem') at high speed due to the low cutoff frequency, and increasing the cutoff frequency of the HPF induces further problems of phase leading and initial starting failure at low speeds. In this paper, the cutoff frequency of HPF was synchronized to the operation frequency of the motor: at low speeds the cutoff frequency was set to low in order to reduce the phase leading of the estimated flux, and at high speeds it was set to high to raise the DC offset removal performance. As a result, the operating range was increased by 200%. Furthermore, a phase compensation algorithm is proposed to reduce the phase leading of the HPF to less than 1.5 degrees over the full operating range. The proposed sensorless control algorithm was verified by experiment with a PM synchronous motor for a washing machine.

The term practical means that you actually use what you learn. Unlike that meaning, however, the curriculum is operated by specific majors of some professors. And we can be seen in many colleges. Jazz is a prime example. Jazz is a genre only for some maniacs and there is not much places to play on the pop scene. But this genre is now packaged as representative studies of practical music. This affects even cram schools, preparing for college entrance exams, while high school students are also learning, playing and preparing Jazz to take the exams. Of course, Jazz is a field of music, but it is a very sad reality, considering it can never be the mainstream of popular music. It has been 20 years since the department of practical music was established at a four-year university. The number of graduates will also be very large. Now that the role of a university is related to employment, it's time to look at how the graduates are getting jobs and whether they are working in music. And it will also be important to ensure that the curriculum of the department is reasonably managed to connect with employment in reality. Practical learning will be not only respond immediately to market changes but establishment and operation of education courses should be carried out accordingly. In this study, we will discuss curriculum of vocal at universities, concrete examples of operations, and reasonable vocal courses that can be connected to employment.
