This study was undertaken to identify ways that enable a successful comeback to everyday life and improvement in the quality of life, by understanding the experiences of cancer survivors in returning to everyday life. Totally, 19 people diagnosed with complete cure after 5 years of cancer treatment, were recruited for the study. Data was collected through in-depth interviews from January 18 to February 25, 2017. One-time interviews took 90 to 120 minutes, and data analysis was achieved by applying the grounded theory. The central phenomenon of 'reality that cannot be escaped' and 'uncertain reality that cannot know tomorrow' was attributed to the causal conditions 'hard reality', 'physical exhaustion', 'psychological exhaustion' and 'economic exhaustion'. Depending on context conditions such as 'lack of family support', 'shift to a vulnerable working class', 'insufficient support system', 'hope for the societal support system', 'daunted gender', 'prejudice against cancer/cancer patients', 'information on life after rare full healing'. The strategy for a successful return was influenced by intervention conditions such as 'robust family fence' and 'effective cancer insurance', which resulted in 'building a new life' or 'enduring'. We conclude that for a successful return to daily lives, cancer survivors require comprehensive information, health and social-welfare interventions.

Coarse aggregate is produced in various ways depending on the location and production method. Currently, the construction industry is in need of a stable supply of coarse aggregate and a way to secure standard quality. The purpose of this study is to examine whether the use of coarse aggregate in 3D printing can help solve this problem. ABS filament was selected for use in 3D printing. CATIA was used for the design of the coarse aggregate, and CUBICON Single Plus was used for the production. Six specimens were produced and cured in water for 28 days. Three of them were made with AE agent, and three were made without it. A compressive strength test confirmed that when the AE agent was used, the compressive strength was greater than the lightweight concrete design criterion specified in the concrete standard specification. This suggests that coarse aggregate produced by a 3D printer may be used for lightweight concrete. A mass production system using this method could help to solve the problems facing the construction industry, such as stable supply and demand for coarse aggregate and securing standard quality.

The concern on new regional geography in Korea has emerged in the 1990s under the influence of paradigm shift of Western geography, that is, the withering of positivist geography and the introduction of grand social theories into geography. New regional geography in Korea also seems to have developed in the rapidly changing process of glocalization of capitalism which has accompanied with the transformation toward post-Fordism with high-tech innovation, development of transportation and communication technology with time-space compression, and increasing social and cultural mobility with change of identity. But it can be pointed out that discussion on methodology for regional geography in Korea has been shrunken since the mid 2000s, and there has been relatively little empirical research with synthetic approach to region. But more concern on methodology in terms of place, territory, network, scale, etc. rather than the concept of region itself has increased, and empirical researches on regions in specific fields of human geography have been promoted. It is argued that the traditional distinction between synthetic and analytic approaches seems no longer significant. But geographers need to extend the concept of region in relation to other diverse spatial concepts, and to purse simultaneously structural analysis on glocalization process and practical strategies responding positively to the process.

This study was conducted to identify the factors affecting the quality of life of cancer patients based on demographic characteristics, health status, and mental health using the results of the 6th National Health and Nutrition Survey. The research tool used the demographic characteristics, health status, mental health, and quality of life of the KNHANES VI-2. Data analysis was conducted using SAS 9.3 version. There were significant differences in the quality of life in the study results by age, gender, economic activity, individual income quartile, subjective health status, mental health status, activity limitation, stress perception, and experience of depression symptoms. Factors influencing the quality of life of cancer patients included age, sex, income quintiles(individual), subjective health status, activity limitation, and experience of depression symptoms, which together explained 39.1% of the quality of life. To improve the quality of life of cancer patients, comprehensive management is required from diagnosis to treatment to return to society. It is also necessary to develop and apply long-term programs including multidimensional approaches and improvement of quality of life, early screening of cancer and cancer prevention education, management of depression symptoms, and social support.

자연적으로 발생되는 파도, 비, 우박 등과 철도, 차량 및 엘리베이터 등과 같은 인위적인 설치, 이동에 의해 발생되는 진동에너지는 우리 일상생활에서 가장 흔하게 발생할 수 있는 에너지원인데, 이러한 진동에너지는 압전 소재를 이용하여 재생 가능하여 최근에는 이에 대한 연구가 활발히 진행되어 왔다. 예를 들면, 미국의 MIT에서는 인간이 걸을 때 신발에 가해지는 압력을 이용하여 전력을 발생시키는 연구를 진행하여 2.9 mW의 전력을 얻었다. 특히 이러한 기술은 인간의 걷기 운동 등과 같은 일상적인 동작으로 필요한 전력을 얻을 수 있고, 세라믹 소자를 이용하기 때문에 전자노이즈가 발생되지 않을 뿐 아니라 반영구적으로 사용할 수가 있어서, 소형 전자기기 등에 서 기존 이차전지를 대체 또는 보완 할 수 있는 기술로 검토되고 있다. PZT계 세라믹스는 높은 유전상수와 우수한 압전특성으로 이러한 압전발전 분야에서 가장 널리 사용되어지고 있다. 하지만 에너지 효율을 높이기 위하여 적층 구조의 제작 시 구조적 특성상 내부전극이 도포된 상태에서 동시 소결이 필요한데, $1000^{\circ}C$ 이상의 높은 소결온도 때문에 소재 원가가 낮은 Ag전극 대신 값비싼 Pd나 pt가 다량 함유된 Ag/Pd, Ag/Pt 전극이 사용되고 있어 경제성이 떨어지는 단점을 갖게 된다. 순수 Ag 전극을 사용하거나 Ag의 비율이 높은 내부전극을 사용하기 위해서는 $900^{\circ}C$ 이하에서 소결되고 우수한 전기적 특성을 보이는 압전 세라믹스 소재를 개발 하는 것이 필요하다. 따라서 본 연구에서는 압전특성이 우수한 $(Pb_{1-x}Cd_x)(Ni_{1/3}Nb_{2/3})_{0.25}(Zr_{0.35}/Ti_{0.4})O_3$ 계의 조성을 설계하고, 소결온도를 낮추기 위해서 2 단계 하소법을 이용하였다. 또한 $MnCO_3$, $SiO_2$, $Pb_3O_4$ 등을 소랑 첨가하여 액상 소걸 특성을 부여하여 소결 온도를 감소시키려는 시도도 하였다. 소결체의 전체적인 제조 공정은 일반적인 벌크 세라믹의 소걸 공정을 따랐다. 최종 소결된 시편을 XRD분석을 통하여 상을 확인하였고 SEM을 이용하여 미세조직을 관찰 하였다. 전기적 특성을 평가하기 위하여 두께를 1mm로 연마한 시편에 Ag 전극을 도포하여 $650^{\circ}C$ 에서 열처리한 후, 분극처리 하였다. Impedance analyzer를 이용하여 압전 특성 (전기기계결합계수 및 기계적품질계수)을 측정 하였고, 압전전하상수는 $d_{33}$-meter로 측정하였다. 본 연구에서는 압전체에 가해지는 하중의 크기, 시편의 크기, 하중을 가하는 방법, 에너지 저장회로의 최적화 등을 다양하게 시도하면서 에너지 변환 및 저장 효율을 평가하였다.

It works as intermediation of communication of publics these days. Since 20 century, We, Koreans, have established new chaotic multi culture with traditional Korean culture and other different culture from everywhere. Meanwhile, we occupied the most powerful semi-conduct and IT indusry. Within those circumstance, people feel very confused in political, cultural and social aspect. The society armed with economy and popularization promotes material satisfaction with this potential possibility of anonymous masses. However, it results to cause loneliness, isolation, alienation, anonymity, non individuality and commodity of culture. In my work, such phenomenon reveals through human character in a city. People are exposed culture of consumption and surrounded and tempted by all those artificial and superficial atmosphere. Human are possessed and exposed to attractive products and visual images. Finally they make themselves stuck in their case of this world. People lose their own identify and shape of bodies. That is our portrait, who are living this moment. Also, this is a symbol that destroys this modern society. As a result, 1 consider such aspects through those elements above to think how to keep and rethink our identity and what to do for this world.

Social changes due to ICT like Big Data, IoT, Cloud and Mobile is progressing rapidly. Now, we get out of the old-fashioned frame was measured at the level of the information society through the introduction of PC, Internet speed and Internet subscribers etc and there is a need for a new type of diagnostic information society framework. This study is the study for the framework established to diagnose and measure post-information society. The framework and indicators were chosen in accordance with the technological society coevolution theory and information society-related indicators presented from authoritative international organizations. Empirical results utilizing the indicators and framework developed in this study were as follows: First, the three sectors, six clusters (items), 25 nodes (indicators) that make up the information society showed that all strongly connected. Second, it was diagnosed as information society development (50.34%), technology-based expansion (25.03%) and ICT effect (24.63%) through a network analysis (ANP) for the measurement of importance of the information society. Third, the result of calculating the relative importance of the cluster and nodes showed us (1)social development potential (26.04%), (2)competitiveness (15.9%), (3)ICT literacy (15.5%) (4) (social)capital (24.3 %), (5)ICT acceptance(9.54%), (6)quality of life(8.7%). Consequently, We should take into account the effect of the economy and quality of life beyond ICT infrastructure-centric when we measure the post-information society. By applying the weighting we should performs a comparison between countries and we should diagnose the level of Korea and provide policy implications for the preparation of post-information society.

This study presents improvement measures at the local government level by analyzing the step-by-step projects of Suwon City's Suwon Village Development Project, which is being carried out with public development assistance in the Kingdom of Cambodia. For this study, realistic research was conducted by visiting the site and interviewing the person in charge. The following conclusions are drawn. First, public development assistance projects for local governments in Korea should be carried out, with detailed programs to implement them under the central government's ODA policy. Second, provided a project is competitively carried out, and is not simply pork barreling or enhancing the external image of local governments, the project should be continued, and supplementary measures taken based on an evaluation system and the results of the project's performance. Third, ODAs in the economic and social development sectors-not sporadic aid among central government ministries and local governments-should be centered on the central government and KOICA while local governments are small. If development cooperation is achieved by focusing on the software sector, criticism that it wastes taxpayers' money is likely to decrease. This study suggests that local governments need to establish ODA plans and cooperate with the central government.

This study attempts to verify the applicability of ceramic membrane as a separator by comparing the power generation characteristics in single-chamber MFCs using ceramic membranes to those in the MFCs using nafion membrane. The generated power in MFCs by using acetate as a substrate was more stable than that by using formate, propionate and butyrate, respectively. It was shown that the generated power by using formate substrate in MFCs was unstable and a little higher than that by using acetate, and the power generated by using propionate and butyrate were lower than that by using acetate. In order to find out the Pt catalyst effect, it was compared the power generated in MFCs using Pt-coated carbon cloth as electrode to that power using normal carbon cloth. The power generated in MFCs using Pt-coated carbon cloth as electrode was 1.2 times higher than that using normal carbon cloth. The Pt-coated carbon cloth was about 5 times more expensive than normal carbon cloth. It is suggested that both power generation efficiency and cost together should be considered in selecting electrodes of MFCs. It was found that the ceramic membrane was superior to nafion membrane by comparing to the power generation characteristics obtained. It was shown that average voltage values were $523.67mV{\pm}49.41mV$ by using synthetic wastewater, in MFCs of ceramic membrane as a separator. While average voltage values were $424.09mV{\pm}79.95mV$ by using synthetic wastewater, in MFCs of nafion membrane as a separator. The organic removal efficiency, 41.7% by using ceramic membrane was a little bit higher than 40.8% by using nafion membrane. This research implies ceramic membrane can be a valid alternative to nafion membrane as a separator when considering the power generation and the efficiency of organics removal.

The purpose of this study is to compare the perceptions of hairdressers, hairdressers-to-be, and ordinary people on hairdressers. For this, 286 hairdressers, hairdressers-to-be, and ordinary people residing in Daegu and Gyeongbuk were surveyed and analyzed. The study results are as follows: First, the job preferred by hairdressers is running their own salon. Most of those involved in the beauty industry considered that anyone who has an aesthetic sense can become a hairdresser, the average education level is college, and 5-10 years of experience would be adequate. On the other hand, the majority of the ordinary people thought different. Second, most of the hairdressers thought that professional theoretical knowledge and skills are required for hairdressers and that they have the role of leading beauty. On the other hand, the majority of the hairdressers-to-be and ordinary people considered that what it takes to become hairdressers are design sense and creativity and that they should take the responsibility of cleanliness and service. Meanwhile, all the research subjects shared common ideas that the competence required for hairdressers is skills and female hairdressers are preferred. Third, the most common cause for hairdressers to move from a workplace to another was wage-related issues, and the most answered entry-level salary was between KRW 1 million and 1.5 million and average working hours a day 9-10 hours. Fourth, the research subject groups showed significant differences in their perception of the occupation of hairdresser. The results suggest that although the social perception of hairdressers is improving, ordinary people still need to change their perception.
