The purpose of this study is to explore quantitatively the success factors of YouTube's music cover channel. Along the process, constructing and testing the measurement for music cover channel's characteristics. The research constructed the measurement items based on results of qualitative studies. To perform the purposes the study suggest a research model which integrated the Post Acceptance Model with five music cover channel's characteristics based on the recent case studies. The five characteristics were contents, video, creator, interactivity, and publicity. The characteristics were integrated with Post Acceptance Model. After testing reliability and validity the research model was revised then, the research hypothesis was tested. The research results show: first, it was found that the content characteristics did not meet the expected value of users. Second, among the five factors of channel characteristics presented in creator's characteristics have the largest effect on user's value perception Third, in the factor analysis process, the content factor and the video were loaded on the same factor thus integrated as one factor. Fourth, satisfaction and intention for continual usage were also loaded on the same factor thus integrated as one factor. The research results suggest that music cover channel operators need to enhance the creator's attraction, communication with user, and publicity in various ways.

Four cONA clones expressed in late root nodules of Canavalia lineata were isolated by differential screening using total RNA from uninfected roots, Clb1 and uricase II cONAs as competitors and named Cnod1, Cne2, Cne3 and Clb2, respectively. Cnod1, hybridized to 1450 nt mRNA, was highly homologous to cysteine proteinase gene from rice and showed nodule-specific expression, especially in late nodules. Cne2, hybrdized to 900 nt mRNA, was moderately homologous to Expressed Sequence Tag of rice and expressed mainly in root nodules. Its expression was increased at 13 OAI and subsequently remained at the same level. Cne3, hybridized to 1700 nt and 1400 ot mRNAs, was highly homologous to tonoplast membrane intrinsic protein TRG31 gene from pea and was expressed strongly in roots and nodules, but weakly in leaves. Temporal expression pattern of Cne3 was coincided with the life cycle of root nodules. Clb2, hybridized to 800 nt mRNA, was expressed from 8 OAI, amplified at 13 DAI and remained steady thereafter.eafter.

Most of military supersonic aircraft use an afterburner. It plays an important role in performing unusual duties for supersonic flight, takeoff, and combat situations. Recently, repetitive fuel leakage from the inner piston packing rubber of afterburner fuel pump in an aircraft J85-GE-21 turbojet engine has happened. These failures have only happened in one manufacturer's parts of two manufacturers. Thus, the cause of these failures was investigated through the comparative analysis for both the failed and the unfailed with two different manufacturers using various analysis methods. The failure analysis was performed using analysis methods such as swelling or swelling ratio, total sulfur content, polymer identification, loading and surface area of carbon black, and hardness. Consequently, the main cause of this failure was identified to be insufficient loading of carbon black as a reinforcing agent, together with small surface area of carbon black and somewhat low sulfur content.

조류는 발생학적 특성상 수정과 초기 배발생을 제외한 거의 대부분의 개체 발생 과정이 난각 속에서 진행된다. 또한 배자가 발생하는 동안 배자의 뼈를 구성하는 석회성분의 거의 대부분은 난각에서 유래한다. 난각 석회성분은 배자유래의 융모성 뇨막(chorioallantoic membrane; CAM)의 모세혈관을 통하여 배자로 이동하다. 배자 발생후기로 가면 융모성 뇨막은 전체 난각과 거의 대부분 밀착하여 배자 발생 후기에 필요한 많은 양의 석회성분을 난각에서 배자로 공급하게 된다. 그러므로 한 개의 난각 속에서 두 개의 배자가 정상적으로 발생되기란 거의 불가능하다.

규합총서는 조선후기에 빙허각 이씨가 저술한 가정학의 총서라 할 수 있다. 이책은 저자가 집안의 딸과 며느리에게 주기 위한 것으로 부녀자들을 위한 교육서라고도 할수 있으 며 가정생활 백과 사전과 같은 성격을 띠고 있다. 규합총서를 통해본 의생활 색생활관리는 간간히 연구되어 왔으나주생활관리의 내용은 연구가 미흡하여 본 연구에서는 이 책의 주택 관리의 내용을 찾아 분석하고 논의하여 보았다 그 결과 첫째 당시의 주택관리에는 자연재를 활용한 바를 볼 수 있었고 둘째 그 내용은 저자가 직접 행해 보고 유용한 바를 수록한 상세 한 가르침이었음을 알 수 있었다 셋째는 주택관리내용이 여성들이 감당할 수 있는 정도로 제한적인 것만을 다루고 있었으며 넷째는 조선후기의 실학사상의 영향을 받은 실천적가르침 을 강조한 바를 알수 있었다.

This study aims to investigate the career development experience of youth in late adolescence who entered a different university after taking a semester off (as known as Bansu in Korean), in depth, applying a phenomenological research method. For the research, this study selected seven adolescents as research participants to reveal the essential meaning of their experience, vividly. The data were analyzed by Giorgi's method to draw components of the experience of research participants. As a result of the research, the career development experience of youth in late adolescence who entered a different university after taking a semester off was systematized into 19 sub-categories and structured into four main categories: "high school years in which academic record was more important than aptitude", "the step away from the dream, being forced to proceed to college", "the time of study to take the exam again, which was an advantage and disadvantage at the same time" and "the wish unfulfilled even with the success of entering a different university." It turned out that the main topic was "the repeated way even after passing the repeat sign." They took the College Scholastic Ability Test (CSAT) once again and came back to the narrow way to enter a prestigious university, but they still compromised the standard made by the older generation. This study has significance for late adolescents' welfare and happiness in that it explored the in-depth meanings of the career development experience of youth who entered a different university by taking the CSAT again after taking a semester off. Lastly, based upon the situation of the increase in the number of students who take the CSAT again, this study suggested better measures for career development during adolescence and the promotion of their quality of life.

The interpretation of observed waveform characteristics identified in refraction and wide-angle reflection data increases confidence in the crustal structure model obtained. When calculating traveltimes and raypaths, wavefront methods on a regular grid based on graph theory are robust even with complicated structures, but basically compute only first arrivals. In this paper, we develop new algorithms to compute traveltimes and raypaths not only for first arrivals, but also for fast and later reflection arrivals, later refraction arrivals, and converted waves between P and S, using the modified wavefront method based on slowness network nodes mapped on a multi-layer model. Using the new algorithm, we can interpret reflected arrivals, Pg-later arrivals, strong arrivals appearing behind Pn, triplicated Moho reflected arrivals (PmP) to obtain the shape of the Moho, and phases involving conversion between P and S. Using two models of an ocean-continent transition zone and an oceanic ridge or seamount, we show the usefulness of this algorithm, which is confirmed by synthetic seismograms using the 2D Finite Difference Method (2D-FDM). Characteristics of arrivals and raypaths of the two models differ from each other in that using only first-arrival traveltime data for crustal structure analysis involves risk of erroneous interpretation in the ocean-continent transition zone, or the region around a ridge or seamount.

This study was conducted to evaluate the effect of a newly developed paste fertilizer on rice growth. It was applied to two vars. of Taeback and Cheonma byeos as a basal treatment. It needs a unique applicator attached to transplant machine for rice plant and was injected about 3cm depth of paddy soils. The polished rice yields were obtained competitively with a 20 percent reduction of N applied with top dressing. Plant development treated paste fertilizer was good compared to control at the early growing stage, however, not different at the late growing stage. Nitrogen uptake in plant was high at the early growing stage in paste fertilizer treatment but there were no significant difference at the late growing stage.

An unusual disease syndrome, partial stem rot and final blight of the whole plants was observed in sesame, Sesamum indicum L., cultivar Pungnyeonkkae and Kwangsankkae grown in the field. Symptoms progressed from water-soaking continuous banding lesions on one side of stem to producing abundant Fusarium growth on the lesion at late stage of pathogenesis. Although wilting of plants was most frequently observed in sesame seedlings when infected with Fusarium oxysporum, reproduction of the partial stem discoloration and rot was possible by soil inoculation, and wound inoculation in old plants. The disease occurred from late July. Mycological characteristics of the isolate Fusarium oxysporum compared with those reported in sesame suggested that the isolate might be F. oxysporum f. sp. sesame.
