This research attempts to extract the factors that generate scientific interest, and verify the effect of extracted factors on the generation of scientific interest in middle school students' observation activity on life phenomenon. In order to analyze interest-generating factors, observation programs were applied four times in the science class of 3rd grade middle school students. And an interview was conducted towards students who had strong scientific interest among students who participated in the observation activity. After classifying the interview results according to the types, and 21 interest-generating factors were extracted. Interest-generating factors were classified into 5 categories; the characteristics of the observation object, the characteristics of the observation activity, the characteristics of the observation result, the characteristics of the observer, and the characteristics of the extrinsic factor. It was verified that interest-generating factors have an effect on the generation of scientific interest in the observation activity. First of all, in order to confirm whether the extracted generation factors would have an effect on the generation of interest in observation activity, as survey of interest-generating factors was drawn up. The observation activity program of 4 times' volume was applied towards third grade middle school students, and survey paper on interest-generating factor was input. Analysis result showed that factors have effect on the generation of interest. That is, it was confirmed that extracted interest-generating factor has a significant effect on the generation of scientific interest. The cause analysis on the uninteresting observation activity was possible, and it would play an essential role in developing an interesting observation activity.

The purpose of this study is to examine the factors affecting the baby boom generation's preparation for old age, and based on that, it will provide foundational data to improve the baby boom generation's preparation for life in old age. According to the study results, with regard to their socio-demographic characteristics, their sex, age, health conditions, average monthly income, attitudes to old age, and anxiety about aging may have significant effects on their preparation for old age. In other words, the degree of preparation for old age is higher in women than men, those who are older, those having better health conditions, those with higher average monthly income, and those with better attitudes to old age, and those whose anxiety about aging is lower. Based on the above study results, the paper intends to make the following political suggestions: first, it is needed to develop preparation for old age services appropriately for each generation's needs and characteristics in consideration of their socio-demographic characteristics. Second, it is necessary to provide education for preparation for life in old age by steps and change their consciousness to enhance their attitudes to old age. Third, it is needed to develop and distribute a variety of mental health programs that can lower their anxiety about aging.

BIPV system not only produces electricity at building, but also acts as a material for building envelope. Thus, it can increase the economical efficiency of PV system by saving the cost for building materials. Bifacial solar cell can convert solar energy to electrical energy from both sides of the cell. In addition, it is designed as 3 busbar layout which is the same with ordinary mono-facial solar cells. Therefore, many of the module manufacturers can easily use the bifacial solar cells without changing their manufacturing equipments. Moreover, bifacial PV system has much potential in building application by utilizing glass-to-glass structure of PV module. However, the electrical generation of the bifacial PV module depends on the characteristics of the building surface which faces the module, as well as outdoor environment. Therefore, in order to apply the bifacial PV module to building envelope as BIPV system, its power generation characteristics are carefully evaluated. For this purpose this study focused on the electrical performance of the bifacial BIPV system through the comparative outdoor experiments. As a result, the power generation performance of the bifacial BIPV system was improved by up to 21% compared to that of the monofacial BIPV system. Therefore, it is claimed that the bifacial BIPV system can replace the conventional BIPV system to improve the PV power generation in buildings.

Objectives The purpose of this study is to examine the characteristics of the experience prescription in 『Donguisusebowon(東醫壽世保元)』. Methods We examined the examples of the experience prescription in the pathology of 『Donguisusebowon』. Afterward, we considered the characteristics about the experience prescription of Junggyeong Jang and the Next Generation Doctors in 『Donguisusebowon』. Results and Conclusion 1. The Junggyeong Jang's experience prescription isn't modified despite the fact that it doesn't fit the constitutional disease and pharmacology, and many experience prescriptions are mentioned to in the pathology of 『Donguisusebowon』. But the Next Generation Doctors's experience prescription is modified, and a considerable number of experience prescriptions are not mentioned to in the pathology of 『Donguisusebowon』. 2. Jema Lee cited all of the Junggyeong Jang's experience prescription except Daesiho-tang(大柴胡湯) as an explanation for the constitutional disease, and cited a prescription that could not be used for the constitutional disease. And the pathological symptom of the Junggyeong Jang's experience prescription was used to establish the system of the Sasang Constitutional Medicine, so the Junggyeong Jang's experience prescription wasn't modifed. 3. Jema Lee cited a prescription that could be used for the constitutional disease. And the pharmacology of the Next Generation Doctors's experience prescription was used to establish the system of the Sasang Constitutional Medicine, so the Next Generation Doctors's experience prescription was modifed. 4. Jema Lee established the Sasang Constitutional Medicine based on the Existing Medicine. It was appeared in composition and name about the table of contents of the experience prescription in 『Donguisusebowon』.

The purpose of this study is to identify gamification techniques and characteristics of digital marketing based on the main information communication, learning, and play of the current consumer group, and to present effective gamification digital marketing plans for the MZ generation. The summary of the research process is as follows. First, the characteristics and definitions of MZ generation and gamification were described and the concept was clarified. Second, domestic and foreign gamification cases were compared and analyzed. Studies show that we should be wary of gamification digital marketing, which fails to reflect the characteristics of the fun-seeking MZ generation by failing to organically connect the mechanisms and structures of gamification, focusing only on visible elements, such as Point, Badge, and Leaderboard. In addition, customers who lose the fun of obtaining rewards and leave because they feel that the rewards (points, badges, leaderboards) they provide are worthless should be prevented.

We have analyzed the short pulse generation using heterodyne techniques. The numerical model for semiconductor lasers under the heterodyne technique is based on the Lang's equation and has been extended in order to take into account the simultaneous injection of the multiple sidebands of the current-modulated laser. The unselected sidebands will affect the optical and RF-spectral characteristics even when the semiconductor laser is locked to the target sidebands.

Hydrogen generation by dissociation of water is described. The major force for the dissociation comes from the oxidation potential of the reactive metal reacting with water whereas the minor role is played by electrical discharge which helps sustain the reaction. A premixed reactive metal/water system undergoes a fast hydrogen generation upon the ignition by an electrical pulse. In another method the reactive metal can be fed into the discharge. Some characteristics of the methods are discussed.

Corona discharge and ozone generation characteristics of a slit dielectric barrier discharge type wire-plate plasma reactor with a third electrode have been investigated. When a third electrode is installed on a slit of the slit barrier, where an intense corona discharge occurs, it is found that a significantly increased ozone output could be obtained. This, however, indicates that the third electrode can activate the corona discharges both of the discharge wire and the slit of the slit barrier in the plasma reactor. As a result, a thin stainless wire, used as the third electrode has a strong effect to influence the corona discharge of the slit and corona wire, especially to the negative corona discharge. Higher amounts of the output ozone and ozone yield, about 1.27 and 1.29 times for the negative corona discharge, can be obtained with the third electrode, which reveals the effectiveness of the third electrode.

Fingerprinting is a widely used positioning technology for received signal strength (RSS) based wireless local area network (WLAN) positioning system. Though spatial RSS variation is the key factor of the positioning technology, temporal RSS variation needs to be considered for more accuracy. To deal with the spatial and temporal RSS characteristics within a unified framework, this paper proposes an extended signal propagation mode (ESPM) and a fingerprint generation method. The proposed spatiotemporal fingerprint generation method consists of two algorithms running in parallel; Kalman filtering at several measurement-sampling locations and Kriging to generate location fingerprints at dense reference locations. The two different algorithms are connected by the extended signal propagation model which describes the spatial and temporal measurement characteristics in one frame. An experiment demonstrates that the proposed method provides an improved positioning accuracy.
