본 연구에서는 선발시스템이 종업원 성과에 미치는 영향을 고찰하기 위하여 지수법과 선별법의 특성에 의한 수리적 모형을 제시하였다. 일반적으로 성과의 증진분은 선발비율이 낮거나 시험과 기준사이의 다중상관관계수가 높을수록 커진다. 또한 선발비율과 다중상관계수가 동일한 경우에는 지수법이 선별법보다 높은 성과의 증진을 결과하였다. 마지막으로 이런 수리적 모형을 선발실무에 적용할 경우에 고려하여야 할 사항을 논의하였다.
면접에 대한 지원자 지각이 면접만족도와 채용제안 수용가능성에 미치는 영향에 관한 실증적 연구
김형식(Hyung Sik Kim),황규대(Kyu Dae Hwang) 한국경영학회 2002 經營學硏究 Vol.31 No.1
Factors which affect applicant decisions concerning jobs are examined. Factor analysis of the applicants` responds yielded five factors: explanation, feedback, equity, personableness and job-relevant information. These factors are significantly related to the applicant`s satisfaction on interview. It was founded that the applicant`s reactions on interview, organizational attractiveness, and perceived alternative job opportunities affected the likelihood of job acceptance. The results suggest that organizations should take into account individual reactions when selection system is designed. Future research needs to investigate applicant`s perception on a broader selection system.

The main purpose of this research is getting more effective method of interview. Though most employers use interview as a recruiting tool, many researchers suspect its validity and reliability. So this research focuses on the influence of interview form and behavior pattern on interview outcome. Sample was taken from nursing in hospital. Experiment was done for the students in business and nursing. The result shows that if interviewer and applicant have the same disposition or not didn't effect the outcome. But when both are extrovert, score was higher. So it can be said that behavior pattern effects interview outcome. Also, structured interview form has less halo effect than unstructured interview. So structured interview can control decision making error effectively.
하수슬러지의 산과 초음파 처리에 따른 ECP(exocellular polymers)의 거동이 탈수성과 침강성에 미치는 영향

The effects on dewaterability and settlability of wastewater sludge according to acid and ultrasonic pretreatment which was expected to change ECP (exocellular polymers) compounds in the sludge and bulk solution was investigated. Though ECP which attached to the sludge could stimulate coagulation of sludge particles by bridging effect, but ECP in the bulk solution deteriorated dewaterability and settlability of the sludge on the contrary. That is as the pH of the solution was decreased to 3 gradually by acid treatment, proportionally ECP in the bulk solution was attached to the sludge flocs and resulted in improvement of dewaterability and settlability of the sludge. In case of ultrasonic pretreatment, with proportional to the intensity and duration of ultrasonic application, ECP was detached and extracted from sludge flocs and these phenomena deteriorated dewaterability and settlability. Also because of the increasement of minute sludge particles according to ultrasonic, dewaterability became so much the worse.
