The main purpose of this paper is to suggest a spatial planning approach to effectively deal with airport noise problems in neighborhoods adjacent to civil airports. Rapid urbanization around the airports, as well as growing concerns on quality-of-life, resulted in ever-growing airport noise complaints, lawsuit, and central government's financial burden. S. Korea government adopted a restriction- and compensation-based airport noise management policy against the problems in mid 1990s. It, however, turns out to be ineffective in guiding incompatible land uses and facilities away from the airports' environs and to encourage compatible ones to locate around the airports. Base on the United State's and United Kingdom's airport noise management practices, therefore, this study suggests a new spatial planning approach that emphasizes the following: 1) diversification of current airport noise mitigation programs, 2) introduction of "sector"-based, spatial management system, and 3) central government's close cooperation with local governments and communities.

A pressure control law to regulate pressure of gas generator is suggested. To design a model based control law, the governing equation which consists of Robert and conservation equation is built and verified through the ground burning test. PID and nonlinear adaptive control laws are designed to analyze the loop response characteristics under the system which has varying eigen properties arisen from combustion volume change. It is suggested that new approach, gain scheduling design, is required to overcome the defects identified from numerical simulation results of the two control laws. The newly suggested scheme shows good control performance even under disturbances and measurement noise.

A pressure control law to regulate pressure of gas generator is suggested. To design a model based control law, the governing equation which is consisted of Robert and conservation equation is built and verified through the ground burning test. PID and nonlinear adaptive control laws are designed to evaluate the loop response characteristics under the system which has varying eigen properties as combustor volume is increased. It is suggested that new approach, gain scheduling design, is required to overcome the defects identified from numerical simulation results of the two control laws. The newly suggested scheme showed good control performance even under disturbances and measurement noise.

The management of wastes within the urban landscape has become a critical concern to both local governments and inhabitants. With landfill capacities steadily decreasing, rapid growth of economy, population and urbanization, citizen awareness of the environment and public health problems occured by existing landfill sites make difficulties in selecting the landfill site. Therefore, this study has been performed to select the optimum waste landfill site using GSIS methodology to reduce the time, cost and effort. As the result of this study, we can investigate many factors synthetically which could not be handled by the former method using hands in the site selection for waste landfill, and we can carry out economically the work of selecting suitable site throughout the vast area.

Influence of other blond components on measuring glucose concentration was analyzed B)food phantom containing five major components was made. The prediction model was developed based on the measurement of absorption spectra including the first overtone glucose band, i.e.. 1500 ∼ 1850 nm. The concentrations were Predicted using the Partial least squares regression. Factor analysis based on Design of Experiment was Performed to study the influence of other components in predicting glucose concentration. Triglyceride does not influence. Albumin and globulin haute minor effects. However, hemoglobin showed substantial response and the compensation of hemoglobin concentration appears to be required for the model of glucose measurement.

As the foodservice industry is labor intensive, the efficient management of human resources is an essential element for improving operational efficiency. This study was designed to investigate the performance level of human resource management in self-operated school foodservices and to examine the relationship between human resource management, organizational commitment, and productivity. Whether these factors rated differently by employment and job types was also examined. Data were collected through questionnaires distributed to 60 dieticians and 240 cooks in Seongnam and Yongin. Frequency analysis, factor analysis, the t-test and multiple regression analysis were tested using Minitab. Human resource management practices rated highly in the dimension of employee training (3.51), followed by working environment (3.39), and turnover management (3.37). In contrast, reward management (1.73) and working condition (1.56) received the lowest score. Organizational commitment scored 3.65 points, and showed that dedication (3.82) was the highest score; however, self-esteem (3.50) was the lowest score. For human resource management, there were significant differences between employment types as full time workers (3.85) rated management more highly than part-time worker (3.43). Overall productivity was fairly high, especially in high school foodservices. Only the performance appraisal had an influence on organizational commitment (${\beta}$=0.292, P<0.05). Productivity was positively correlated with human resource management (r=0.432, P<0.001) and organizational commitment (r=0.36, P<0.01). In conclusion, school foodservices need to establish objective performance standards, and increase employee morale by enhancing reward systems and working conditions. In particular, irregular employees require training with job performance standards and given a proper reward program, depending on their performance, to improve organizational commitment.

This study tested the effectiveness of commercialized smartphone apps in improving walking activities among college students. 66 participants were randomized into each of four groups that was used different behavior change strategies: monetary rewards app, goal setting and feedback app, gaming app, and self-monitoring control group. 45 participants who completed the experimentation was included in data analysis. Repeated measures ANOVA resulted in statistically significant time by groups interactions in recorded step counts, self-reported completed plans and self-reported walking activities scores. The Goal-setting and feedback group and the gaming group resulted in increase in both step counts and completed plans. The results were discussed in the framework of behaviorism.

본 연구는 성과관리가 조직의 지속적인 성장과 발전의 혁신도구로써 조직성과에 영향을 미친다는 측면에서 공공부문의 균형성과표(BSC) 운용의 성공요인과 고려사항을 바탕으로 연구모형을 설정한 후 이를 실증적으로 분석하였다. 이를 위하여 성과관리를 위한 BSC의 추진 관리 단계인 계획, 실행, 평가, 환류, 등 순환주기에 관련된 변수들을 독립변수로 하고, 조직성과에 관련된 변수들을 종속변수로 선정하여 독립변수가 종속변수에 미치는 영향을 분석하였다. BSC를 구축 운영하고 있는 공공기관의 BSC 성과관리시스템 담당자에게서 설문조사를 실시하여 분석한 결과, BSC 운영 단계별 하위변수들은 상호간에 영향을 미치며, 조직성과에도 유의미한 영향을 미치는 것으로 나타났다. 이러한 분석결과에 따른 정책적인 시사점은 성과관리를 조직 내에 촉진 유지하기 위한 조직적, 정책적, 전략적 환경을 조성하여야 한다는 점이다. 또한 공공부문에서 성과관리제도가 실패하는 가장 큰 이유는 객관적인 평가지표가 명확히 설정되지 않았거나 보상체계가 불충분하기 때문이다. 공공부문의 경쟁력 확보를 위해서는 구성원이 전략적 사고의식을 가져야 한다.

PFP성형기술은 사출성형시 수지를 금형내에 환전히 채운후 저압의 공기를 이용하여 기포를 발생시켜 수지의 체적수축분을 기포의 성장에 의해 보상해주는 기술이다. 이방법은 일반 사출성형에서 많이 발생하는 싱크마크나 휨과 같은 변형문제를 해결하여 줄수 있으며 높은 압력을 필요로하지 않는다는 잇점을 가지고 있으나 이러한 최신공정에 대한 체계적인 연구는 미흡한 실정이다. 최근에 제시된 PFP성형공정의 모델링은 기포의 성장이 수지의 체 적수축에 의한 것이라는 가정을 근거로 기포핵이 생성된 이후의 기포성장을 모사하였으며 모델링에 해석결과는 몇가지 가정에도 불구하고 실험결과를 잘 설명하였다. 본 연구에서는 모델링이 가지는 문제점을 분석하고 기포성장의 메카니즘을 보다 체계적으로 이해하기 위하 여 실험적인 방법을 적용하였다. 많은 인자들을 효과적으로 고려하기 위하여 실험계획법을 적용하였으며 이를통하여 기포핵의 생성과 기포의 성장에 공기압 등이 매우 중요한 역할을 한다는 사실을 확인하였다. 이러한 결과는 모델링과 함께 PFP공정에 대한 체계적인 이해 뿐만 아니라 금형설계 및 성형조건의 설정등의 실제적인 문제해결에도 도움이 될것으로 기 대된다.

건설사업정보화(CALS)는 국토교통부에서 1998년부터 추진한 정보화사업으로 건설사업정보시스템의 확충 운영과 건설정보표준의 고도화, 건설기술정보 확충 기능개발 등 3개 분야로 사업을 진행하고 있다. 건설사업정보시스템과 건설정보표준 성과물의 지자체 확대보급 계획은 있으나 지자체용 프로그램 개발이 미흡한 실정(일부 광역단체는 자체적으로 건설사업관리, 시설물관리, 용지보상 등을 개발 운영 중이나 대부분 지자체에서는 시스템을 미보유)이다. 전산자원의 활용도 제고와 시스템 정보표준의 개발 운영 예산의 효과적인 집행을 위해 종합적인 사업추진 방안을 위한 기초조사가 필요하다.
