운전 온도 $35^{\circ}C$, 평균 유기물부하 $3.1{\;}kgCOD/m^3/day$ 및 수리학적체류시간 10일에서 혐기성 연속회분식공정에 의한 분뇨처리를 수행하였다. 공정의 평가는 대조 소화조로 완전혼합형의 소화조와 병행하여 수행되었다. 본 실험에서 분뇨는 고농도의 암모니아성 질소와 침전성 고형물을 함유하고 있음에도 불구하고 희석 없이 소화가 가능하였다. 혐기성 연속회분식공정에서 고형물은 급속하게 증가하여 완전혼합형의 대조 소화조에 비하여 소화조내 고형물(biomass)의 농도가 2.4배로 증가하였고, 가스발생량에 있어서도 대조 소화조에 비해 현격한 증가를 보였으며 그 증가율은 205~220%에 달했다. 부가적인 침전 시설이 없이도 혐기성 연속회분식공정의 유출수질이 대조 소화조 보다 높게 나타났는데 상징액 기준으로 휘발성고형물 제거율은 혐기성 연속회분식공정이 대조 소화조 보다 12~14% 높았다. 한편, 혐기성 연속회분식공정의 운전인자로 반응/침강비(R/T ratio)를 조사한 결과 R/T비가 1인 경우가 3의 경우보다 가스발생량, 메탄함량 및 유기물 제거율이 약간 높았으나 큰 차이는 없었다. 위의 실험결과들로부터 혐기성 연속회분식공정은 고농도의 암모니아성 질소와 침전성 유기물을 함유하고 있는 분뇨의 처리에 효과적이고 안정적인 공정으로 판단된다.

This study tried to examine the relationship between superior leadership and emotional support from co-workers on task performance through performance evaluation fairness and self-efficacy in order to find factors that affect the task performance of a company in an uncertain market environment. For this purpose, 500 copies of questionnaire data were collected from corporate employees, and the research hypothesis was verified using Smart PLS 3.0. As a result of the study, superior leadership and emotional support from co-workers showed a positive (+) effect individually on the fairness of employee performance evaluation, Performance evaluation fairness showed a positive (+) effect on self-efficacy. Through this study, it was found that the fairness and self-efficacy of the performance evaluation accepted by employees affects work performance, providing a theoretical foundation for subsequent researchers. Practical implications are suggested to inspire employees to take on a challenge by managing them properly. In future research, based on the results of this study, various studies are needed on the factors that an organization must have for task performance.

This research focuses on the perceived marketplace influence(PMI: A belief that recognizes the effect that an individual's actions will have on the behavior of other consumers in the market and thus drives them to act on fair trade consumption) of consumers who may act as a more fundamental explanatory alternative to the gap in attitudes and behaviors of fair trade products. The purpose of this study is to investigate the relationship between consumer's self - determination psychological needs (autonomy, competence, relevance), influence (personal influence, market influence), and the assets of fair trade products. As a result of the empirical analysis, it was found that among the major psychological needs related to self-determination, the variables other than competence and the perceived influence relations of consumers can be directly formed, and the perceived consumer effectiveness(PCE) has a positive influence on perceived marketplace influence(PMI). It is also found that the perceived influence of consumers(PCE, PMI) has an influence on the consumers' perceived equity of Fair Trade products. The results of this study will provide an opportunity to theoretically explain the gap between consumers' attitudes and behaviors of Fair Trade products, which is a part of ethical consumption, and provide important implications for the establishment of marketing strategies.

This study examined the effects of procedural justice on two facets of OCB (OCBI and OCBO) in local public enterprises and the mediating role of intrinsic motivation in these relationships. We verified the hypothesis established by a structural equation model based on PLS. The research data were collected through a survey of 269 employees working for local public enterprises. Research has shown that procedural fairness has a positive effect on intrinsic motivation, organizational citizenship behavior directed at individuals (OCBI), and organizational citizenship behavior directed at the organization (OCBO), while intrinsic motivation has a positive effect on OCBI and OCBO. In addition, intrinsic motivation has been found to have a partial mediating effect in the procedural justice-OCBI relationship and the procedural justice-OCBO relationship respectively. Finally, we present theoretical and practical implications that organizations need to activate intrinsic motivation so that members can induce voluntary organizational civic action through improved procedural fairness.

The actual complaint handling response of the company serves as an important success factor for the company to reduce defection rate of customers who have complaints. In this regard, this study sought to divide the company's complaint handling response into substantial compensation, favorable employee behavior and organizational procedures, empirically verify the effects of the customer's justice perception on trust and satisfaction, and thus to present the importance of the company's actual response. To this end, the data obtained from a survey of 210 customers who filed complaints directly to the company was analyzed using SPSS and AMOS. The research results can be summarized as follows. The compensation for customers with complaints has a significant effect on justice, and the favorable employee behavior also has a significant effect on justice. In addition, the organization procedures about handling complaints have a significant effect on justice. Especially the justice as justice perception was found to affect the future behaviors of customers such as trust and satisfaction. Based on these findings, this study presented implications and suggested future research.

This study is to understand how why users fail to service and how users use service recovery strategics. This study use equity theory to understand how perceived justices have influence on trust and to identify how trust has influence on service quality. This study used scenario techquie to get user experience of service failure in smartphone application. Scenario is composed of 16 sub scenario and we conducted survey with each case. The results show that interpersonal justice and distributed justice have significantly influence on trust. However, procedural justice has not influence on trust. Service quality is influenced by trust. This paper conclude with statements of implications and limitations of the study results.

Scheduling management is one of the most important factors for the efficient performance of construction projects. Various computer-aided solutions for schedule management have been developed, but they are not commonly used in practice. This study conducted surveys on scheduling management methods and the related solutions to identify their status and problems in practice. Based on the results of the surveys, this study also developed a scheduling assistant program to improve the usability of scheduling management solutions. Through the developed program, the usability of scheduling management solutions will be improved in practice, thus enabling efficient scheduling management.

This study examined the structural relationship among personal belief in a just world, presence of meaning in life, self-control, and aggression in college students. For this research, self-reported data from 427 college students were analyzed by gender, using structural equation modeling. Results indicated that personal belief in a just world predicted aggression regardless of gender. The mediating effect of self-control was non-significant among both women and men groups. The mediating effect of presence of meaning in life and self-control was significant among only women. It means that personal belief in a just world predicted presence of meaning in life and self-control, which consequently contributed to aggression among women. It is noteworthy that this study examined the concrete mechanism to reduce aggression by gender. Based on these findings, intervention strategies were discussed.

현재 로켓. 추진연소관을 제작하는데 이용되고 있는 유동성형공정을 유한요소기법을 이용 해석을 수행하였으며 또한 기존 해석접근법과의 비교도 기술 되어 있다. 대부분의 기존 해석방법은 압출공정의 유사성에 근거하여 해석이 수행되어 왔던 반면 본 연구에서는 유동성형 공정을 연속적인 쐐기 압인과의 유사성으로 보아 해석을 수행하였다. 그 해석결과로는 유동성형시 발생되는 성형된 부분에서의 두께증가량이 예측되었다. 또한 공정후 비롯되는 격자 형태는 유사하나, 응력 등 다른 변수들의 분포가 압출공정에 근거한 해석결과와 상이하게 나타났다.
