In order to predict the performance of biological wastewater treatment plant, the kinetic parameters and stoichiometric coefficient must be known. The theories and experimental procedures for determining the biological kinetic parameters were discussed in this study. Respirometric analysis in the batch reactor was carried out for the experimental assessment of kinetic parameters. A simple procedure to estimate kinetic parameters of heterotrophs and autotrophs under aerobic condition was presented. The difficulties in the interpretation of COD and VSS measurements encouraged the conversion of respirometric data to growth data. Maximum specific growth rate, yield coefficient, half saturation constant and decay rate of heterotrophic biomass were obtained from OUR(Oxygen Uptake Rate) data. Maximum specific growth rate of autotrophic biomass was obtained from the increase of nitrate concentration. The aim of this paper is to estimate the kinetic parameters of heterotrophic and autotrophic biomass by means of the respirometric analysis of activated sludge behavior in the batch reactors. These procedures may be used for the activated sludge modeling with complex kinetic parameters.

In recent years, the world's free trade system has been severely damaged by a series of protectionist measures in the United States and anti-globalization practices such as Brexit. Against this background, RCEP, the world's largest trade agreement, was officially signed on November 15, 2021. The RCEP provided a good working basis for the establishment of a Korea, China, and Japan free trade zone. First, this paper describes the current status of Korea-China-Japan trade cooperation and the current status of the trilateral telecommunication industry. Second, this paper simulates the changes in the overall economy of China, Japan, and Korea when tariffs are reduced to 0%, 5%, and 10%, respectively, after the establishment of a free trade zone using the 8th edition GTAP database. Then, using the simulated data changes and using the 2019 data as a benchmark, we calculated the changes in the RCA index for the three countries' telecommunications industries for the three tax rates. In the end, it is concluded that the economies of the three countries will grow to different levels in many ways when the Korea, China, and Japan free trade zone is established. Japan's telecommunications industry will not be significantly affected, Korea will grow significantly with higher tax rates and China will grow significantly with lower tax rates.

After Protestant missionaries delivered the gospel to Korea in the 1880s, Korean Protestantism has pursued qualitative growth following quantitative growth. Pastors and scholars are continuing their efforts for qualitative growth in various fields such as theology, ministry, social participation, ethics, education, counseling, history, and spirituality. Prayer has been a significant spiritual resource and method in the history and for the faith of Korean Protestant churches. Historical and theoretical research on Korean Protestant prayer traditions has been continuously performed, and it is time to re-establish and renew the prayer traditions for the new generation and context of the Protestant churches. In this historical time, it is necessary to summarize the Korean Protestant prayer traditions and describe their significance for the change of Korean Protestantism and its prayer education. This study analyzes the characteristic elements of the Korean Protestant prayer tradition and discusses its significance in the church and Christian education. In addition, it analyzes the cause and background of the establishment of a specific prayer element in Korean Protestantism and describes the relationship with the topics currently being emerged. Through the research on the prayer traditions, this study reflects on the meaning of the Korean Protestant prayer tradition to Christian education and discusses the content, method, and purpose of future education in relation to Korean Protestant prayer. This study argues that prayer education should be conducted from the perspective of Christian history and tradition as a whole with understanding the characteristics of Korean Protestant prayer traditions and the educational and non-educational elements of prayer.

Since This study is about game novel. I'm going to discuss the flow and features of game novels. Game novels developed in Korea, the game industry developed and made it possible. Fantasy novels, Muhyeop novels, and the generation of games met, so game novels could develop. By looking at the trends of game novels, I want to lay the foundation for the study of popular literature genre. The reason behind the emergence of game novels is the meeting of the game generation and the novel. The types of game novels can be distinguished according to the 'location of the main characters' and 'the narrative style'. It is not the best, but it is the minimum work to identify the genre. The biggest characteristic of game novels is their connection to games. It also uses the system of the real game. Another characteristic is that a variety of variations are possible with other genres. Game novels were influenced by fantasy novels and Muhyeop novels. Game novels now hold a solid place in the realm of popular literature. But the limits are also clear. It is the repeated use of game novel progression. Here are the limitations that game have to overcome. In addition, active research should be carried out. This study is intended to promote research on these game novel genres.

To find the influence of water temperature, tank color and illumination in feeding, growth and blind-side hypermelanosis of starry flounder, Platichthys stellatus, in the present study, we performed a series of temperature, background color and illumination intensity test for 180 days (From June to December). The test was done in duplicate at 100 fish/tank (430% of initial covering area [PCA]) with the selected ordinary juvenile flounder (TL $17.3{\pm}0.5cm$, BW $82.5{\pm}0.2g$). The rearing was performed in darkgreen FRP aquarium tanks ($H100cm{\times}L100cm{\times}W100cm$; bottom area $1m^2$) lighten with average 1,000 lux and 230 lux, and in white FRP aquarium tank ($H100cm{\times}L100cm{\times}W100cm$; bottom area $1m^2$) lighten with average 230 lux of light intensity. We investigated correlation of daily food intake (DFI) with water temperature and salinity, and compared the influences of background colors and light intensity in DFI, food efficiency (FE), growth, survival rate, and ratio of malpigmented blind-side area and ambicolored fish ratio. In DFI, although it was not related with salinity, the amount was significantly decreased under 0.5 g/fish/day in summer and winter season, but was significantly increased over 1.5 g/fish/day in autumn season showing from $10^{\circ}C$ to $20^{\circ}C$ in water temperature. In background and illumination test, DFI, FE and survival rate showed no difference among three groups. The ratios of malpigmented blind-side area and ambicolored fish were also not significantly different among three groups, indicating that the blind-side hypermelanosis of starry may be governed not by background color (or light intensity) but by a genetics external trait inherited from parents.

The government budget for promoting startup have been skyrocketed as catching up with increasing demands for high-tech startup by disruptive innovation resulted from rapid technology change. However, major trend of startup have still fallen on self-employed type of startup due to the lack of expertise and fund in spite of desperate government policy efforts. In reality, the access to high-tech startup has been very limited and too high huddle to would-be entrepreneur. This paper implement empirical analysis on the effects of entrepreneur competency and satisfaction level to government support, considering these as the KSF for the growth and success of high-tech startup, to the performance of the company. In particular, it focus on defining unique characteristics of high-tech startup through differential proving by the backgrounds of entrepreneur such as major, R&D experience, patent possession, CTO possession. This research carry out survey to 217 entrepreneurs in high-tech company in Daejon and Daegue at R&D Special Innopolis Zone. Research results are as follow. First, entrepreneurial achievement competencies, conceptualization competencies, network competencies and market recognition competencies positively affect the financial and non-financial performance and organizational and technical competencies, while organizational and technological competencies only positively impact on non-financial performance. Second, the satisfaction level of government support showed a positive moderating effect on entrepreneurial achievement competencies and financial performance, while no significant effect in other competencies. Third, positive differential effect by the technological background of entrepreneur such as Major, R&D experience, patent possession, CTO possession) have been confirmed. This paper deliver several significant implications and contributions, First, it propose classified and systematized entrepreneur competency through the domestic and foreign literature reviews. Second, it proves the need for the wider spread of team based startup culture rather then sole startup. Third, it also proves the important role of technological background of entrepreneur among the characteristics of high-tech startup.

As a pioneering study on wife rape, this study focuses on identifying the prevalence, the correlates of the individual social class and domestic violence background, and the perception of wife rape. This study uses the data based on the survey 224 married men and women who reside in Daegu, Korea. The result of this study shows that about 42.4% married men have experienced any type of wife rape. The most prevalent wife rape is force only wife rape(36.4%). Battering rape(12.1%) and sadistic rape(10.4%) are also found as significant coercive sexual issue among Korean couples. Monthly income and child abuse experience are found as significant predictors for the wife rape of married men. In addition, wife's religious enthusiasm is also negatively correlated with wife rape propensity, although the effect is not strong. The living standards is found as a strong correlate of women's propensity of being raped from their husbands. Thus, our practical attention should be given to those who have financial difficulties in low economic status, and to those who have significant child abuse experience, in order to prevent wife rape. Overall, married men and married women show pretty negative perceptions of wife rape, however, some of them are still positive of it. It is interesting that married men show a very defensive attitude against the proposal of establishing legal punishment for the people who commit wife rape. According to the gender, there is a considerable difference between men and women in terms of both the degree of acceptance of, and the demand for legal punishment of wife rape. It is problematic that the married women with a greater experience of being raped by husbands show far greater tolerance of wife rape than those with a less experience of it. These findings give us significant practical implications for social work intervention.

The continued development of smart devices representing smart phones and tablet PC has made significant changes to the ICT ecosystem. Along the development of smart devices, consumers' needs are also becoming increasingly diversified in addition to their rising expectations. Thus, in order to fulfill the changing customer needs, corporations in the ICT ecosystem have recently focused on appcessory products that are interlinked and utilized in existing smart devices. This study particularly analyzes the two corporations, Samsung Electronics and SK Telecom, which recently plunged into appcessory business. By the case study of these two companies based on the theories of ecosystem and platforms, this study analyzes the current status of the appcessory market, the potentials and significances of the business, business background of the two corporations, and the status of leadership competition in the appcessory market. In the case of Samsung Electronics and SK Telecom, the study shows that both corporations acquired new growth powers in the appcessory market with their entry into existing or other relating markets. Also, since the appcessory business is highly related to their existing businesses, each company was able to take advantages based on the capability that they already possessed and this relationship had positive effects on their overall businesses. In addition, the two corporations had common strategies in increasing their competitiveness by identifying internal weaknesses and building external cooperations. On the other hand, since the two companies have different business areas, their business background, business strategies, and the effects of expectations varied to each other. Thus, this study identifies commonalities and differences between recent smart platforms and corporations' engagement in the fierce leadership competition in the appcessory market.

The Purpose of this study is to point out some attributes of intrinsic and social background and status attainment process and a life-style of public library directors in KOREA. The data obtained from 188 respondents in 1999 were used for analysis. Some of the main findings are as follows： $\circled1$ The majority of the directors has a career as a teacher or local public administrators rather than a librarian. $\circled2$ The birth places of the directors are scattered all over the country. and those who were born in rural area account for about of all respondents. In rural area. it might be difficult for them to access information on newly developing profession like librarianship. $\circled3$ Although the educational level of directors themselves is higher than general public. $\circled4$ Library schools which give students high grade knowledge and training of library and information science are not so many, and hence directors are primarily local public administrators rather than qualified librarians. $\circled5$ Many directors did not aspire to become librarians. rather they got the post after they had been working as a teachers or lawyer, local public administrators. $\circled6$ If the library services of better quality are provided all over the country, urban or rural, and library schools in higher education are developed and have much more satisfactory substance, and abler library directors. And then we can expect that the qualified librarians's director system in public libraries will become an accomplished fact.
