The rapidly changing 21st-century knowledge and information society is emphasizing converged education that crosses various academic fields. In particular, the society expected the cultivation of the talent who balance scientific creativity and artistic sensitivity by adding arts to the existing converged education revolving around science and technology. However, at present, most STEAM education has been actively conducted with a focus on science and technology, whereas the subject of arts has been regarded or utilized as a supplementary means. Its problem is that the educational characteristics and values of art education have not been effectively utilized in educational terms and this could lead to superficial integrated education. In this respect, this study had the knowledge of various fields, such as science, technology, and mathematics, utilized usefully during the process of experiencing and creating arts. Accordingly, this study designed an education programs as with the case of Nam-Jun Baek who expanded the dominion of arts by creatively utilizing his own time's scientific technologies. In this educational process, the target program was developed in a manner that enables EPL to be utilized essentially as the study's knowledge-based tool and medium. The results of applying this educational program in 5th-grade elementary school students showed that the program has positive effects on the creative attributes of the students.

This paper presents a capacitor loaded tunable bandpass chip filter using multiple split ring resonators (MSRRs) with two transmission zeros. To obtain high selectivity and minimize the chip size, asymmetric feed lines are adopted to make a pair of transmission zeros located on each side of passband. Compared with conventional filters using cross-coupling or source-load coupling techniques, the proposed filter uses only two resonators to achieve high selectivity through a pair of transmission zeros. In order to optimize selectivity and sensitivity (insertion loss) of the filter, the effect of the position of asymmetric feed line on transmission zeros and insertion loss is analyzed. The SOI-CMOS switched capacitor composed of metal-insulator-metal (MIM) capacitor and stacked-FETs is loaded at outer rings of MSRRs to tune passband frequency and handle high power signal up to +30 dBm. By turning on or off the gate of the transistors, the passband frequency can be shifted from 4GH to 5GHz. The proposed on-chip filter is implemented in 0.18-${\mu}m$ SOI CMOS technology that makes it possible to integrate high-Q passive devices and stacked-FETs. The designed filter shows miniaturized size of only $4mm{\times}2mm$ (i.e., $0.177{\lambda}g{\times}0.088{\lambda}g$), where ${\lambda}g$ denotes the guided wave length of the $50{\Omega}$ microstrip line at center frequency. The measured insertion loss (S21)is about 5.1dB and 6.9dB at 5.4GHz and 4.5GHz, respectively. The designed filter shows out-of-band rejection greater than 20dB at 500MHz offset from center frequency.

In this study, we conducted a comprehensive study to analyze the environmental behavior of airborne Ni for the proper establishment of basic control tactics based on the metal concentration data sets collected from the major cities in Korea for the 14 year period(1991 through 2004). The mean concentration of Ni determined from all cities during the entire study period varied from as little as 7.38+6.70 ng $m^3$(Won Ju) to the maximum of 41.4+26.2 ng $m^3$ in a highly industrialized city of An San. However, the mean concentrations of Ni from most cities generally fell in the range of 10 to 20 ng $m^3$. When the Ni concentration data in all cities are compared between the former half(1991 to 1997) and the latter half period(1998 to 2004), a reduction in its concentration levels was seen dominantly between the two study period. Comparison of seasonal patterns generally indicated the enhanced concentrations of Ni during spring/winter relative to summer/fall term. The overall results of this study suggest that the source processes of Ni are diverse enough to exhibit moderately diverse patterns between different cities. Considering that relative enhancement in Ni levels is observed from most of industrial and/or large scale cities, a development of adequate control tactics for Ni is highly desirable.

세계가 일일 생활권화 됨과 더불어 국제교류가 활발해지므로써 횡문화 간호 연구는 전문직 간호(Professional Nursing)에 있어서 매우 중요한 부분을 차지하고 있음을 많은 문헌을 통해서 알 수 있다(Brink, 1976 : Leininger, 1977 : Roberston & Boyle, 1987). 횡문화 간호연구는 서로 다른 문화적 배경을 가진 사람들을 잘 이해하고 그들의 건강을 돌봄에 있어서 더욱 효과적이고, 안전한 간호를 할 수 있을 뿐만 아니라 간호이론 개발, 간호모형(Model) 개발에 있어서도 매우 중요한 역할을 한다고 믿는다. 본 연구는 1984년에서 1987년 사이에 전문적 간호연구지에 실린 10편의 횡문화 간호연구와 관련된 논문들을 발췌하여 간호지식체의 본질적인 과정인 비판적 문헌고찰을 통해 각 논문들을 비교 분석 한 것으로써, 미래의 간호연구를 위한 간호실무, 간호교육, 간호연구 방법 및 간호 행정면에서 그 적용성을 높여줄 것이다. 비판적 문헌고찰을 위한 기준은 Burns와 Grove(1987)의 방법을 참고하여 아래와 같이 선정하였다. 1. 분석대상 : 목적, 가설 진술, 문헌고찰, 표본조사, 방법론적 논점, 결과 해석 2. 이론적 틀의 유도 흑은 통합 3. 발전적인 간호수행을 위한 중요성, 적용성 및 제언 이상의 내용으로 비교 분석을 해본 결과 1984년에서 1987년 사이에 발표된 횡문화 간호에 관한 논문들의 주제는 주로 여성을 대상으로 한 건강돌봄, 자가간호, 건강신념, 수유, 임신 그리고 간호사와 소수민족 노인과의 의사소통 양상 등으로 나누어 볼 수 있었다. 이론적 틀은 주로 사회학, 정신심리학, 인류학 이론으로부터 도출되었고, 오직 두 편만이 간호 이른에 틀을 둔 것으로 나타났다. 1. 10개의 논문의 가설과 목적의 분석에 있어서 4편의 논문은 목적과 가설이 구체적으로 진술되어 있었고, 나머지 6편은 목적이 전반적으로 진술되어 있었으며 가설도 구체적이지 않았다. 이러한 제한점은 각 논문의 연구자가 문헌고찰을 충분히 하지 못하고 단지 수편의 논문만을 제시 한 데서 비롯되었다고 분석 해 볼 수 있겠다. 2. 문헌고찰 부분에서는 각각의 연구주제를 지지해줄 수 있는 문헌들이 충분히 고찰되지 못하였고, 이론적배경 또한 횡문화 이론과의 관련성이 적었다. 또한 횡 문화 연구에 기초가 되는 연구대상자의 사회 인구학적 특성과 역사적 배경은 잘 나타났으나, 이론적 연구와 경험적 연구 간에 괴리가 있었다. 3. 표본추출방법은 문화에 기반을 둔 대상자를 선정한다는 점에서 한계성 이 있었다. 4. 방법론적 이유로는 대상자와의 면담시간이 구체적으로 기술되지 않았으며, 고유한 언어를 통역하는 과정에서 의미론적 문제에 대한 고려가 부족하였다. 면접과 기록과정에서 보면 자료의 기록과정과 분류 및 분석과정이 명시되어 있지 않았다. 참여관찰과 면접방법을 사용시 이에 대한 자세한 기술이 되어 있지 않았다. 5. 연구결과의 적용 및 이에 대한 논의는 상당히 제한되어 있었는데, 수편의 연구만이 방법론 문제점과 앞으로의 연구분야에 대한 전망을 제시하였으며, 특이한 것은 어 떤 연구자도 이른 개발을 위한 적용 및 임상실무적 차원에서 간호에 대한 제언을 하지 않았다.

Conventional methods of measuring ground resistance and ground resistance field measurement are used to measure voltage drop according to the resistance value of the site by applying current by installing a constant interval of measurement electrode. If the stratified structure of the site site is unique, errors in boundary conditions will occur in the event of back acid and the analysis of the critical ground resistance in the ground design will show much difference from simulation. This study utilizes the Arduino module and smart ground measurement technology in the convergent information and communication environment to develop a reliable smart land resistance measuring device even if the top layer of land is unique, to analyze the land resistance and accumulate data to predict the change in the age of the land. Considering the topographical characteristics of the site, we propose a ground resistance measuring device and its method of measuring ground resistance so that the auxiliary electrode can be installed by correctly positioning the angle and distance in measuring ground resistance. Not only is ground resistance value obtained through electrodes installed to allow accurate ground resistance values to be selected, but it can also be used as a useful material for installing electrical facilities in similar areas. Moreover, by utilizing reliable data and analyzing the large sections of the site, a precise analysis of the site, which is important in ground design as well as construction cost, is expected to be used much in ground facility design such as potential rise.

The general programming channels, newly introduced around the beginning of the 2010s, have grown into powerful journalistic agencies, the far-reaching social influences of which are not confined by the economic effects within the South Korean media industry. They are now rendered to become part of major socio-political institutions that try to secure their privileges based on broadcast journalism, and to widen their business opportunities through those special kind of social practices. This research has taken a path of theoretical endeavour to devise a conceptual framework that will effectively lead to a series of academic investigation into the socio-political characteristics of general programming channels. To this end, specific attention is paid to such theoretical and conceptual resources as the instrumentalization of media by the politics, the political sociology of media power, media-political parallelism, and the structural coupling between the political and the media systems. This paper suggests that general programming channels have emerged as a new interface that accommodates and actualizes the structural coupling between the two societal subsystems, and in the course of that, they undercut the vulnerable basis of media public sphere, effectively replacing it with entertaining media-political sphere constructed and managed by themselves. This sphere is where the media system's logic and the poltical system's logic are intertwined, simutaneously accelerating not only the mediatization of the politics but also the politicization of the media.

Nowadays, newspaper industry faces a crisis in terms of two aspects: First, in this multi-channel era, it has competed with the online journalism appearing in many digital media. Second, with the decrease of numbers of readers and political participation, the roles of newspaper has to be changed accordingly. The concept of civic journalism emerged as a solution in this context. The purpose of the study is to explore the factors in how journalists perceive the civic journalism. The Q-methodology was adapted to identify the factors composing of the belief, values, attitudes, ideas, and opinions toward the civic journalism. Total of 24 Q-sample (statements) were sorted by 27 P-sample (journalists) who were selected by their gender, years of service, and the like. The Quanl program finally produced 3 factors that were interpreted and named as follows: Factor I, the Complimentary Journalism, the civic journalism would fulfill the functions that traditional journalism has neglected. Factor II, the Alternative Journalism inducing the citizen's participation in the public areas. Factor III, the Functional Journalism, emphasizing dysfunction of the civic journalism.

In this study, the indoor fine dust concentration in an office of the Korea Knowledge Industry Center was measured for about 80 hours when the concentration of atmospheric PM_2.5 was very high. The effect of the operation of the air cleaner and the forced ventilation system on the indoor PM_2.5 was investigated, and the particle size distribution of the indoor and outdoor particles was analyzed. When forced ventilator and air purifiers were partially used, the indoor PM_2.5 concentrations were maintained between 27.7 ㎍/㎥ and 32.9 ㎍/㎥ when the atmospheric PM_2.5 was 127.7 ㎍/㎥ to 141.6 ㎍/㎥ during working hours. It is more effective to operate the air purifier without operating the forced ventilation system when the concentration of the PM_2.5 is high since the PM_2.5 penetrating the installed filter is continuously introduced indoor from the outside.
