This study aims to illustrate the essence of meaning through sexual minorities' participant experiences in a sexual minority community. This research intends to explore essential meaning structure revealed in sexual minorities' reasons for joining a sexual minority community and in their experience in community activities. The study participants were 8 sexual minorities, and data was collected by in-depth interview. Data analysis was described using Giorgi's analysis methodology in phenomenological research method. As a result, the sexual minorities' participation was consisted of 13 meaning units, 6 derived topics, and 3 essential topics, which were 'An unquenchable thirst', 'Another world called oasis', and 'Real estrangement' Moreover, based on the essential topics, the study participants' common meaning of essence was analyzed as 'spiritual diaspora'. Sexual minority communities shall contribute to developments of own organizations through mutual compensations by vitalizing exchanges with other communities based on this study. Also, the communities should the variety in sexual minorities to allow various people's participation. People's awareness on sexual minorities must be transformed so that closed communities can change. Comprehensive knowledge on sexual minorities should be distributed in the social welfare fields so that sexual minorities may search solutions on issues through various access not limited to certain communities.

The purpose of this study is to analyze the cognizance of sexual minority by applying Q methodology, as well as to provide preliminary data for improving sexual minority's image. The study process let P sample, the study participants, use Q-sorting methodology to sort Q sample, which is composed of statements from July 1 to 20, 2017. 21 participants sorted 32 statements and 3 types of sexual minority cognizance were produced as a result. Those types are 1(N=8), 2(N=5), and 3(N=8), which are type friendly human rights enthusiast, type whereas negative stereotypical, and type neutralist. Friendly human rights enthusiast types agreed to ensure sex minority groups' rights as a general protection, whereas negative stereotypical types had strong discrimination and prejudice towards sex minority groups due to lack of related knowledge. Furthermore, neutralist types showed an objection to negative stereotypes against sex minorities, but they did not entirely agree to homosexuality either.

The purpose of this study was to explore nurses' experiences toward nursing with LGBT patients. A phenomenology was used for the study. Data were collected from August 1st to October 30th, 2020 using open-ended questions by in-depth interviews of the participants in one-on-one setting. Participants were nurses who have experience of caring LGBT patients(n=6). Interview data were analyzed using Colaizzii's method of phenomenology. Nurses' experiences toward nursing with LGBT patients in this study had varied, often understanding and sometimes conflicting. As results of the interviews, the 4 categories and 9 theme clusters were identified. The 4 categories included 'Ambivalence', 'Careful and difficult nursing practice', 'Lack of training for diverse and professional care', 'Becoming a nursing professional'. Nurses in this study had expressed diversely nursing experiences about LGBT patients. Most participants showed complex understanding. This study highlights the lack of adequate didactic and clinical preparation makes nurses feel difficult to care for LGBT patients. Therefore, it should be developed effective training and education programs on LGBT health that nurses received from their educational programs.

The purpose of this study was to investigate families' responses and attitudes and the experiences of Korean LGBT individuals after revealing their sexual identity and sexual orientation and to determine how families' attitudes affected the mental health of these individuals. For this purpose, in-depth interviews were performed with 12 male and female LGBT participants, ranging from 19-30 years of age, who resided in Seoul and metropolitan areas, and reported coming out to or being outed by their families. One-to-one interviews were carried out using semi-structured questions, and the data from the interviews were analyzed using consensual qualitative research (CQR). Most of the families had very negative responses and attitudes to the participants coming out and exhibited rejection or avoidant attitudes; only a few of the families responded with receptive attitudes. As a result, the LGBT participants reacted with friction and coping behaviors, such as persuasion, participation in professional counseling, abandonment or avoidance, and running away from home. Most of the effects of the families' attitudes on the participants were negative psychological effects, such as anger, sadness, a sense of alienation, depression, anxiety, fear, trauma, helplessness, lowered self-esteem, alcohol dependence, and suicidal ideation and attempt, while receptive attitudes provided a sense of stability. For all participants, they reported that they were more likely to be hurt by their families' negative attitudes than by social attitudes. This study is significant because it provides framework for specifying families' attitudes and LGBT individuals' experiences after coming out in Korean society. It also outlines LGBT individuals' coping behaviors, psychological difficulties, and the process of coming out and provides suggestions for individuals to overcome. The results are expected to help counselors create practical strategies to better understand LGBT individuals and the psychological difficulties they may experience and provide proper interventions while counseling both the individual and the family.

Theoretical maximum methane yield of glucose at STP (1 atm, $0^{\circ}C$) is 0.35 L $CH_4/g$ COD. However, most researched actual methane yields of anaerobic digester (AD) on lab scale is lower than theoretical ones. A wide range of them have been reported according to experiments methods and types of organic matters. Recent year, a MET (Microbial electrochemical technology) is a promising technology for producing sustainable bio energies from AD via rapid degradation of high concentration organic wastes, VFAs (Volatile Fatty Acids), toxic materials and non-degradable organic matters with electrochemical reactions. In this study, methane yields of food waste leachate and sewage waste sludge were evaluated by using BMP (Biochemical Methane Potential) and continuous AD tests. As the results, methane production volume from the anaerobic digester equipped with MET (AD + MET) was higher than conventional AD in the ratio of 2 to 3 times. The actual methane yields from all experiments were lower than those of theoretical value of glucose. The methane yield, however, from the AD + MET occurred similar to the theoretical one. Moreover, biogas compositions of AD and AD + MET were similar. Consequently, methane production from anaerobic digester with MET increased from the result of higher organic removal efficiency, while, further researches should be required for investigating methane production mechanisms in the anaerobic digester with MET.

In the Integrated Two-Phase Anaerobic Digestion (ITPAD) process, acid and methane fermentation take place in one reactor, which has advantages to cope with organic load variation and reduce foot-print required, compensating disadvantages of Conventional Separated Two-Phase Anaerobic Digestion (CSTPAD). In the present work, organic matter degradation efficiency and biogas generation amount and other performance parameters of the ITPAD fed with food waste leachate were analyzed. In addition, feasibility study on the ITPAD method was performed by comparing its digestion efficiency with that of the CSTPAD. Organic matter alteration and biogas generation of the integrated method were examined for approximately 130 days based on the 5ton/day scaled pilot plant. Experiment results revealed that organic matter removal rate was 80% for mean food waste leachate input amount of $4.1m^3/day$. The biogas generation rate was $63.0m^3$ per ton of food waste leachate input, corresponding to the input VS amount of $0.724m^3/kg-VS_{added}$, and methane content of generated biogas was approximately 61.3%. The ITPAD has a comparable or higher organic matter removal efficiency compared to the conventional separated two-phase anaerobic digestion method. Consequently, the ITPAD method has a great need to commercialize a food waste leachate treatment technology against highly concentrated organic waste leachate.

The primary goal of this study is to examine the factors that affect how satisfied sexual minorities are with their lives. This study focuses on how sexual minorities perceive social stigma, the social influences involved in its perception, and the effects this perception has. Using stress-coping theory, this study looks at how social stigma, as a perceived stress, affects social support and self-esteem, how the stigma influences the degree to which individuals "come out" in an effort to cope, and the resultant effects of this coping mechanism on life satisfaction. The data used if from a sample of 478 individuals who self identify as gay, lesbian or bisexual. It was collected through an online survey. Using SEM, the quality was evaluated by analyzing the measurement model, and the relationship of the variables included in the theoretical model was verified by analyzing the structural model. The results of this study show that social stigma directly affects the life satisfaction of Korean sexual minorities. It significantly influences the social support they receive(from family and sexual minority peers), and their self-esteem. The degree to which the individual "comes out" is shown to affect life satisfaction as well. In contrast, the mediating effect of heterosexual support is shown to be insignificant. Based on the analyses, practical strategies regarding social stigma, social support, self-esteem, and "coming out" are suggested for sexual minorities. The social stigma should be reduced and society-scaled campaigns promoted in order to improve their level of life satisfaction. In addition, institutional protection should be developed and specialized educational courses on human rights provided which will empower these minorities with self-help mechanisms. Furthermore, issues such as establishing support system and providing a social welfare system for the sexual minority community are discussed.

This study analyzed domestic media articles from 1920 to 2017 using R 3.4, a big data analysis tool. In addition, it examines the sexual minority discourse reproduced through the media for about 100 years, focused on the role of the film as an art of struggling with the projective aversion to sexual minorities. sexual minorities in movies are not abominable. They are people we already know in our daily lives, and they are just different in sexual orientation. In general, sexual minorities are less likely to encounter in everyday life, so they are experienced and perceived through what the media present. It is noteworthy that the representation of sexual minorities in the media is formed as a major agenda of our society by publicizing the problems underlying society on the surface. It causes social issues to be raised by revealing and highlighting the problems that are regarded as alienated and avoided from the mainstream's gaze. The content provided by the media enables a three-dimensional experience of subjects who have not experienced it by themselves, and has a decisive influence in correctly recognizing and judging society. Media content suggests that it can be a powerful weapon of recognition struggle that can naturally fight against social hatred without using methods such as demonstrations or protests.

Anaerobic digestion (AD) is one of the most widely used process that can convert the organic fraction of waste activated sludge (WAS) into biogas. However, most researched actual methane yields of anaerobic digester (AD) on lab scale is lower than theoretical ones. Bioelectrochemical, anaerobic digester was used to increase methane yield from waste activated sludge. The influence of anaerobic digestion sludge and raw sludge mixing ratio (3:7, 5:5) on methane yield and organic matter removal efficiency were explored. As a result, when the mixing ratio of bioelectrochemical anaerobic sludge was 5:5 compared with 3:7, the highest methane yields were 294.2 mL $CH_4/L$ (0.63 times increase) and 52.5% (7.5% increase), the bioelectrochemical anaerobic digester(5:5) was more stable in the pH, t otal alkalinity and VFAs, respectively. These results showed that the increase in the mixing ratio of anaerobic digestion sludge was found to be effective for maintaining the stable performance of bioelectrochemical anaerobic digester.
